Teams often confront exogenous events that induce discontinuous change and unsettle existing routines. In the immediate aftermath of such events (the disruption stage), teams experience a dip in their performance and only over time regain their previous performance levels (in the recovery stage). We argue that prohibitive voice that allows teams to manage errors better is instrumental for preventing performance losses in the disruption stage. Whereas, promotive voice that helps teams innovate or improve team processes, can facilitate steeper and more positive performance trajectories in the recovery stage. We also propose that voice is especially functional when teams confront higher change intensity and, thereby, highlight that voice is particularly important when change events cause greater discontinuity in the task environment. We found general support for our theory in a correlational field study involving 172 production teams in which we examined over time trajectories in objective team performance, and a field experiment involving 88 teams in a different production setting, where team members were trained, incentivized, and provided opportunities to engage in voice. We discuss the implications of our findings for literature on voice, team adaptation, and resilience. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Background: Novel coronavirus pneumonia (NCP), or coronavirus disease 2019 (COVID-19), is a worldwide health threat that has affected millions of people globally. Traditional Chinese medicine (TCM) has been introduced for the treatment of COVID-19. However, efficacy differs among herbal medicines, and the ideal prescription pattern for TCM herbal formulae for COVID-19 treatment needs to be explored. Therefore, the data mining method has been used in this study to analyze the TCM prescription pattern for COVID-19. Objective: The aim of this study was to analyze the TCM prescription pattern in Regional Schemes in China for COVID-19 in order to provide a new reference for the use of TCM in COVID-19 treatment. Methods: By searching the TCM treatment protocols of COVID-19 in 23 Regional Schemes, TCM syndromes and herbal medicines were analyzed by data mining. The Ancient and Modern Medical Case Cloud Platform (V2.1 personal Edition) was used to perform frequency statistics, correlation analysis, and cluster analysis. A total of 82 TCM syndromes and 171 Chinese herbal medicines were found. The course of the disease can be divided into the early stage, middle stage, severe stage, and recovery stage. Results: In the early stage, the focus is primarily on resolving dampness, dispelling cold, and diffusing the lungs. In the middle stage, the treatment priority is clearing heat and resolving toxins, promoting lung function, and relieving asthma. In the severe stage, the focus is on tonifying Qi, restoring Yang, and relieving the depletion of Yin and Yang. In the recovery stage, the main treatment is to invigorate the spleen and regulate Qi, tonify Qi, nourish Yin, and clear residual disease. There are certain differences between the Regional Schemes and the Nation Schemes, but the core prescription pattern of the former is consistent with the latter. The effectiveness of these 171 Chinese herbs include but are not limited to inhibiting COVID-19, strengthening immune system function, preventing heart failure, acting as antioxidants, oxidative stress inhibitory effects, maintaining organ function, and improving leukocyte survival. Conclusion: This study may help to improve understanding of TCM herbal prescription pattern, practices, reveal the efficacy of combinations of Chinese herbs, and provide new ideas for TCM treatment for COVID-19.

The COVID-19 pandemic has become a worldwide health crisis. So far, most studies have focused on the epidemiology and pathogenesis of this infectious disease. Little attention has been given to the disease sequelae in patients recovering from COVID-19, and nothing is known about the mechanisms underlying these sequelae. Herein, we profiled the serum proteome of a cohort of COVID-19 patients in the disease onset and recovery stages. Based on the close integration of our proteomic analysis with clinical data, we propose that COVID-19 is associated with prolonged disorders in cholesterol metabolism and myocardium, even in the recovery stage. We identify potential biomarkers for these disorders. Moreover, severely affected patients presented more serious disturbances in these pathways. Our findings potentially support clinical decision-making to improve the prognosis and treatment of patients.

This work is aimed at investigating the structural deterioration and the frost heaving force evolution characteristics of flawed rocks using a self-developed frost heaving force (FHF) measurement system. Three kinds of preflawed rocks with different flaw geometry parameters were used to conduct the FHF measurement tests. The testing results reveal five distinguished stages from the frost heaving force evolution curve; they are the inoculation stage, explosive stage, decline to steady stage, recovery stage, and sudden drop stage. In addition, a secondary frost heaving phenomenon is found, and the secondary peak value is lower than the initial peak value. Moreover, the FHF decreases with increasing the F-T cycle number, and its decreasing rate becomes faster at a high F-T cycle. The frost heaving force is affected not only by flaw geometry but also by the lithology. For low-pore hard rock, damage propagates quickly after the occurrence of freeze-thaw damage. It is suggested that the mesoscopic structure of rock affects the water migration and water-ice phase transformation, and rock can be fractured by FHF in the preexisting flaws.

Background: There are about 200,000 patients in China who need to undergo valve replacement surgery each year. With the promotion and application of the Fast-Track Surgery concept and the increase in hospital bed turnover rate, the average hospital stay of patients undergoing CVR surgery has been significantly shortened, and thus the patients are still in the recovery stage rather than fully recovered when they are discharged from the hospital. Good preparation for discharge can improve patients’ post-discharge self-care ability, reduce the risk of re-admission, and save medical resources. Objective: To describe the status of readiness for hospital discharge among postoperative patients that have undergone CVR, and to explore its influencing factors. Methods: The general information questionnaire, the Readiness for Hospital Discharge Scale and the Quality of discharge Teaching Scale were utilized to investigate 130 post-CVR patients admitted to the Cardiothoracic Surgery Department of a tertiary A-Class hospital in Guangzhou from July 2019 to October 2020. Results: The Readiness for Hospital Discharge Scale was at a moderate level with a total score of 163.88 ± 39.082, while the Quality of Discharge Teaching Scale was also at a moderate level with a total score of 194.09 ± 40.643. Multiple linear regression analysis revealed that the quality of discharge guidance, gender, and occupation were the influencing factors of CVR patient’s readiness for hospital discharge. These three variables jointly explained 45.8% of the total variation. Conclusion: The level of CVR patients’ readiness for hospital discharge is at a moderate level, and the quality of discharge guidance positively affects patients’ readiness for discharge. Therefore, in clinical work, attention should be paid to patient discharge guidance. Personalized health education should be implemented to improve the quality of patient guidance.

Disaster waste clean-up after large disasters is one of the core activities at the recovery stage of disaster management, which aims to restoring the normal functioning of the disaster affected area. In this paper we considered a waste clean-up system consists of (i) demolition operation, (ii) collection of waste from customer nodes to temporary disaster waste management sites (TDWMSs), (iii) processing at TDWMSs, and (iv) transportation of the waste to final disposal sites in the recovery of disasters. A multi-objective mixed integer programming model is developed to minimise the total clean-up cost and time. Three different approaches are developed to solve the problem, which are tested with artificial instances and a real case study. Results of artificial instances indicate that the models developed can be used to obtain close to optimal solutions within an acceptable computing time. Results of the case study can facilitate the decision-makers to develop the waste clean-up with minimised total cost and clean-up time by selecting the right location of TDWMSs and setting up the proper waste clean-up schedule.

This paper mainly studies the problem of irregular flights recovery under uncertain conditions. Based on the analysis of the uncertain factors affecting the flight, taking the total delay time and the total cost of flight delay as the objective function, and considering the constraints of flight plan and passenger journey, an uncertain objective programming model is constructed. Finally, taking OVS airport temporarily closed due to bad weather as an example, the results show that better quality optimization scheme can be obtained by integrating passenger recovery with narrow sense flight recovery stage and implementing integrated recovery.

Objectives To investigate the relationship between the dynamic changes of serum 2019-nCoV IgM/IgG and immunity alteration for patients after 6-month hospital discharge. Methods One IgM(+) and IgG(−), 32 IgM(+) and IgG(+), 38 IgM(−) and IgG(+), and 40 IgM(−) and IgG(−) patients were included. Demographic data were collected. IgM and IgG antibodies, hypersensitive C-reactive protein (hs-CRP), interleukin-6 (IL-6) and lymphocyte subsets in serum were determined at weeks 0, 2 and 4. Results The hs-CRP and IL-6 levels of all patients were within the normal ranges. The number of patients with all lymphocyte subset testing items within normal ranges was 12/110 (10.9%) at week 0, 15/110 (13.6%) at week 2 and 18/110 (16.4%) at week 4. The percentages of CD8 + cells, NK cells and B lymphocytes in the IgM(+) and IgG(+) group were quite different from those in the IgM(−) and IgG(+) group and the IgM(−) and IgG(−) group, with much higher percentages of CD8 + cells and much lower percentages of NK cells and B lymphocytes at weeks 0, 2 and 4. Twelve IgM(+) patients in the IgM(+) and IgG(+) group converted to IgM(−), and the percentages of NK cells and B lymphocytes in these patients were significantly increased at week 4. Conclusions The changes of serum IgM and IgG are closely related to immunity in patients in the recovery stage. However, immunity does not recover when the patients test negative for these antibodies.

To investigate the post-liquefaction shearing behaviour of saturated gravelly soil, laboratory tests were conducted using a static-dynamic multi-purpose triaxial apparatus. In addition, numerical simulations using the discrete element method (DEM) were performed to preliminarily understand the micro-mechanism of gravelly soil in monotonic loading after liquefaction. The influences of dry density, initial confining stress and degree of liquefaction on the post-liquefaction shearing behaviour of gravelly soil were discussed, and the evolution of the micro-parameters of the granular system was also analysed. The results show that the stress-strain responses of gravelly soil after liquefaction can be divided into three stages: (1) low strength stage, (2) super-linear strength recovery stage, and (3) sublinear strength recovery stage, which are distinctly different from those of the general saturated gravelly soil without previous cyclic loading. The initial state and prior dynamic stress history have significant influences on the post-liquefaction shearing behaviour of gravelly soil. The DEM simulation revealed that the average coordination number sharply increases, the contact normal shows an obvious orientation distribution, and the destroyed force chain backbones are reconstructed in the monotonic reloading process after liquefaction. The evolution of the micro-parameters of the granular system clearly reflects the interior interaction process and micro-mechanisms in the particles during the three different stages of the macro-mechanical behaviour of gravelly soil.

Coronavirus disease 2019 (COVID‐19) caused by severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) has become a worldwide pandemic since it emerged in December, 2019. Previous studies have reported rapid antibody response to SARS‐CoV‐2 with the first 2‐3 weeks after symptom onset. Here, we retrospectively described the dynamic changes of serum IgM and IgG specifically against SARS‐CoV‐2 in later weeks (mainly 4‐10 weeks) in 97 hospitalized patients with COVID‐19. We observed that serum IgM and IgG, especially in patients with moderate‐to‐high levels, declined significantly between week 4‐10 after illness onset. Notably, IgG levels in high percentage of patients (77.5%, 31/40) rapidly declined by half, from 212.5 (range, 163.7‐420.3) to 96.3 (range, 75.0‐133.4) AU/ml, within 1‐2 weeks in the second month and then sustained around 100 AU/ml until discharge from hospital. Significant reduction of IgM was also observed as SARS‐CoV‐2 nucleic acid converted to negative (p=0.002). In the recovery stage, serum IgG declined significantly (early vs. late recovery stage, n=16, p=0.003) with a median reduction of 50.0% (range, 3.7‐77.0%). Our results suggested the decline of IgM may be an indicator of virus clearance and recovery patients may have robust immunity against reinfection within at least 3 months after illness onset. Yet, the rapid reduction of IgG by half arises serious concerns on the robustness and sustainability of humoral immune response in the future period after discharge, which is crucial for immunity strategy and developing vaccine.

Similar to other regions in Japan, the Kyushu region is also known to be prone to disasters. A strong earthquake in Kumamoto and Oita prefectures in the Kyushu region occurred in April 2016. Some tourist destinations closed and cancellations by a large number of travelers (both domestic and inbound) had a significant impact on the tourism industry. This paper explains a methodology to evaluate the impact of earthquake disasters on the Kyushu region’s inbound tourism economy. An IRIO table is estimated with 15 sectors and 245 municipalities and is used to calculate the output and spillover effects on seven prefectures, the capital cities, and several sightseeing cities in the Kyushu region. The inbound regional demand and backward linkage output are evaluated at monthly level after the earthquake. The findings show that Fukuoka prefecture has the highest spillover effect values totally, followed by Oita and Nagasaki prefectures. Furthermore, the highest spillover in the capital city was in Fukuoka, followed by Nagasaki, and Kagoshima. Regarding sightseeing cities, Beppu has higher spillover effects value, followed by Yufu, and Kitakyushu. Within a short period of time, the net effect of the monthly level indicates that the economic damage in Kumamoto and Beppu cities is widespread. However, the economic benefit in Fukuoka city implies less spillover effects. The results suggest that regional economic effects should be assessed at the recovery stage after a disaster based on short- and long-term aspects.

Penguins face a major thermal transition when returning to land in a hypothermic state after a foraging trip. Uninsulated appendages (flippers and feet) could provide flexible heat exchange during subsequent rewarming. Here, we tested the hypothesis that peripheral vasodilation could be delayed during this recovery stage. To this end, we designed an experiment to examine patterns of surface rewarming in fully hypothermic (the cloaca and peripheral regions (here; flippers, feet and the breast)

Background/Aims Both apathy and depression occur during the recovery period following stroke; however, the relationship between post-stroke apathy and depression is still unclear. The present study investigated the clinical course of apathy and its association with depression, cognitive function and daily function during the recovery period after stroke. Methods A total of 42 patients (29 male and 13 female, aged 69.1 ± 12.4 years) who had experienced stroke participated in this study. Each participant was assessed using the Apathy Scale, Self-rating Depression Scale, Mini-Mental State Examination, Clinical Assessment of Attention and Trail-Making-Test parts A and B. Quality of life was evaluated using the Stroke Specific Quality of Life Scale. Physical function and functional status were assessed using the Brunnstrom Stages of Stroke Recovery and Functional Independence Measure respectively. Results The incidence of apathy did not change from the time of admission to discharge. Apathy Scale score did not correlate with Self-rating Depression Scale score at admission, but it did correlate at the time of discharge. Patients with apathy after stroke suffered from greater cognitive disturbance and attention and executive dysfunctions than those without apathy. Total Functional Independence Measure score did not correlate with Apathy Scale or Self-rating Depression Scale score, but there was an association between Self-rating Depression Scale score and the Functional Independence Measure motor and Brunnstrom scores at discharge. Conclusions Apathy and depression had different relationships with cognitive and physical function during the recovery stage after stroke. The prevalence of apathy and depression changed, with the interrelationship between apathy and depression altering during the recovery period. Symptoms of apathy and depression should be distinguished from each other and appropriately evaluated to provide effective intervention to support physical and mental recovery after stroke.

While traditional Chinese medicine has displayed a positive and effective role in saving lives of COVID-19 patients, Tuina, which is an important component in Chinese medicine, has also shown its merits in enhancing the immune function and relieving symptoms in COVID-19 patients. This article elaborates the long history of Tuina in treating and preventing epidemic diseases and its effect in improving the immune function. It also introduces some special Tuina methods, for instance, sputum drainage by the back-patting method to enable the discharge of sputum; slant-scrubbing method applied on the hypochondriac regions to bring the effect of soothing the liver to regulate qi, which may also relieve anxiety of patients with COVID-19; and spine-pinching method to enhance human resistance to diseases, which is more suitable for the elderly and for children with mild or common types of COVID-19 and can also be used for health care and disease prevention among the general population. Tuina methods for children using the common children's specific Tuina points and manipulations to improve children's body constitution are also mentioned in the article. Self-acupoint Tuina for health care, including acupoints for prevention purposes, acupoints for early clinical stage (mild stage) and recovery stage, as well as acupoints for children health care and specific operations, is also illustrated in the article. Moreover, basic exercises for health care, such as eight-section brocade, Shaolin internal exercises, six-character formula, and change of tendons, are also presented. In the final analysis, this article is aimed at some ideas and feasible applications of Tuina therapy in the prevention and treatment of COVID-19, in the hope to provide some worthy experience and introduce methods in preventing and fighting against COVID-19 to people all over the world.

This qualitative study describes the psychological experience of patients hospitalized with COVID-19. These patients went through 3 psychological stages: extremely uncertainties during the initial diagnostic stage, complicated feelings of negativity during the treatment stage, and positive growth in the recovery stage. It is important for nurses to provide holistic care.

The international trade of waste has come under public spotlight in recent years with China, the world’s main waste sink for several decades, effectively banning its waste imports in 2018 and subsequently starting a waste crisis in Australia. This article compares the perspectives of orthodox economics, circular economy and political economy on waste economics and policy in Australia. Taking an approach combining both qualitative and quantitative analysis, this article finds that the political economy of Australia’s waste crisis can be understood in terms of two phases: (1) an expansionary phase in Australia’s waste industry from the 1990s onwards, driven by export-oriented growth and neoliberal policy which ultimately led to a waste crisis in 2018, and (2) an emerging recovery stage for the industry led by circular economy policy and more domestically oriented development. These findings contribute to ongoing discourse on the circular economy agenda, demonstrating that in the case of Australia’s waste crisis, circular economy is more of a pragmatic strategy to stimulate economic recovery rather than some radical change towards environmental sustainability.

We present an integrated analysis of urine and serum proteomics and clinical measurements in asymptomatic, mild/moderate, severe and convalescent cases of COVID-19. We identify the pattern of immune response during COVID-19 infection. The immune response is activated in asymptomatic infection, but is dysregulated in mild and severe COVID-19 patients. Our data suggest that the turning point depends on the function of myeloid cells and neutrophils. In addition, immune defects persist into the recovery stage, until 12 months after diagnosis. Moreover, disorders of cholesterol metabolism span the entire progression of the disease, starting from asymptomatic infection and lasting to recovery. Our data suggest that prolonged dysregulation of the immune response and cholesterol metabolism might be the pivotal causative agent of other potential sequelae. Our study provides a comprehensive understanding of COVID-19 immunopathogenesis, which is instructive for the development of early intervention strategies to ameliorate complex disease sequelae.

On 16 April 2016, an earthquake of Mw 7.8 shook the coast of Ecuador, causing the destruction of buildings and a significant number of casualties. Following a visit by the authors to the city of Portoviejo during the debris removal and recovery stage, it was noted that several reinforced concrete buildings located on corners had collapsed in the central part of the city. These buildings were characterized by the presence of masonry at the edges of the buildings but not between the two mostly open-plan facades on the corner for practical reasons. This article reviews the effect of masonry infill panels on the seismic response of reinforced concrete structures. For this, a model that contains the geometric and mechanical characteristics typical of collapsed buildings was generated and subjected to nonlinear analysis, with both static and dynamic increments. The results show the clear influence of the masonry infill panels on the structural response through the torsional behavior that is reflected in the evolution of the floor rotations. Finally, dynamic incremental analysis is used to obtain the collapse fragility curve of the building, and a new damage measure based on floor rotations is proposed.

Seedlings in regenerating layer are frequently attacked by herbivorous insects, while the combined effects of defoliation and shading are not fully understood. In the present study, two Leguminosae species (Robinia pseudoacacia and Amorpha fruticosa) were selected to study their responses to combined light and defoliation treatments. In a greenhouse experiment, light treatments (L+, 88% vs L−, 8% full sunlight) and defoliation treatments (CK, without defoliation vs DE, defoliation 50% of the upper crown) were applied at the same time. The seedlings’ physiological and growth traits were determined at 1, 10, 30, and 70 days after the combined treatment. Our results showed that the effects of defoliation on growth and carbon allocation under high light treatments in both species were mainly concentrated in the early stage (days 1–10). R. pseudoacacia can achieve growth recovery within 10 days after defoliation, while A. fruticosa needs 30 days. Seedlings increased SLA and total chlorophyll concentration to improve light capture efficiency under low light treatments in both species, at the expense of reduced leaf thickness and leaf lignin concentration. The negative effects of defoliation treatment on plant growth and non-structural carbohydrates (NSCs) concentration in low light treatment were significantly higher than that in high light treatment after recovery for 70 days in R. pseudoacacia, suggesting sufficient production of carbohydrate would be crucial for seedling growth after defoliation. Plant growth was more sensitive to defoliation and low light stress than photosynthesis, resulting in NSCs accumulating during the early period of treatment. These results illustrated that although seedlings could adjust their resource allocation strategy and carbon dynamics in response to combined defoliation and light treatments, individuals grown in low light conditions will be more suppressed by defoliation. Our results indicate that we should pay more attention to understory seedlings’ regeneration under the pressure of herbivorous insects.

Background: The coronavirus disease-19 (COVID-19) and its variants have increased rapidly worldwide since December 2019, with respiratory disease being a prominent complication. As such, optimizing evaluation methods and identifying factors predictive of disease progress remain critical. The purpose of the study was to assess late phase (≥3 weeks) pulmonary changes using intensity-based computed tomography (CT) scoring in COVID-19 patients and determine the clinical characteristics predicting lung abnormalities and recovery.Methods: We conducted a retrospective study on 42 patients (14 males, 28 females; age 65±10 years) with COVID-19. Only patients with at least 3 CT scans taken at least 3 weeks after initial symptom onset were included in the study. Two scoring methods were assessed: (1) area-based scoring (ABS) and (2) intensity-weighted scoring (IWS). Temporal changes in the average lung lesion were evaluated by the calculating the averaged area under the curve (AUC) of the CT score-time curve. Correlations between averaged AUCs and clinical characteristics were determined. Results: Using the ABS system, temporal changes in lung abnormalities during recovery were highly variable (P=0.934). By contrast, the IWS system detected more subtle changes in lung abnormalities during in COVID-19 patients, with consistent week-to-week relative reductions in IWS (P=0.025). Strong relationships were observed with D-dimer and C-reactive protein (CRP) levels on admission, with hazard ratios (HR)(95%CI) of 5.32 (1.25-22.6)(P=0.026) and 1.05 (1.10-1.09)(P=0.017), respectively. Conclusion: Our results suggest COVID-19-mediated pulmonary abnormalities persist well-beyond 3-weeks of symptom onset, with intensity-weighted rather than area-based scoring being more sensitive. Moreover, D-dimer and CRP levels were predictive of the recovery from the disease.

Coronavirus disease 2019 (COVID-19) is a new disease characterized by lung damage and involvement in multiple tissues and organs in the whole body. Some of the patients may have long-term impairment and dysfunctions, including pulmonary fibrosis, heart, liver, kidney, nerve, and immune system. Rehabilitation has certain beneficial effect in the acute stage, and especially in the recovery stage, including improving respiratory function, exercise endurance, self-care in daily living activities, as well as psychological support, etc., Rehabilitation is not offside or absent. A reasonable rehabilitation program needs scientific research to avoid arbitrary conclusions.

Relevance. Unsatisfactory effectiveness of treatment of chronic periimplantitis, which makes 40-60%, is associated with a persistence of a bacterial film on the implant surface, as well as with inconsistency of stages of anti-inflammatory, restorative and supportive treatment. Purpose. To discuss an improved approach to restorative treatment of chronic periimplantitis using modified reconstructive technique. Materials and methods. The technique was substantiated using axiomatic method of theoretical analysis. The modified reconstructive technique is based on application of split-thickness submucosal-periosteal flap with blood supply base, which has sufficient reparative-regenerativepotentialand stability in conditions of inflammatory macro-and microenvironment. We have carried out treatment of chronic periimplantitis in two patients using the modified reconstructive technique at the recovery stage. Results. Preliminary assessment of the obtained results of use the modified reconstructive technique showed normal postoperative course and favorable outcome: low surgical stress response under conditions of primary chronic inflammation in the area of the implanted structure; low level of biological response of the submucosal-periosteal autograft with blood supply base as opposed to free grafts and osteoplastic materials; good condition of sutures in the early and medium postoperative period. Conclusion . Application of the modified reconstructive technique can enhance the success of rehabilitation treatment inpatients in chronic periimplantitis.

Backgrounds: Neural biomarkers to predict motor recovery have been used in the field of rehabilitation. Functional connectivity (FC) among the brain regions recorded by functional magnetic resonance imaging systems have been reported, but convenient method to estimate FC for clinical situation has not been established.Objectives: This observational study investigated the relationship between neural functional connectivity obtained by electroencephalography (EEG) and the upper limb function in patients during recovery stage after stroke.Methods: Twenty-four patients in the recovery stage between 4 and 8 weeks after the onset of stroke (mean age: 62 ± 12 (SD)) were enrolled. The EEG signals were obtained by five electrodes placed on the motor-related areas (C3, C4, FC3, FC4, and FCz in the International 10-20 system) for 60 sec at rest and during finger movement on the affected side, and amplitude envelope correlations as measures of FC among the areas were calculated. Fugl-Meyer Assessment (FMA) was used to assess upper limb motor function.Results: The FMA scores evaluated at 4W (33 ± 24 (SD)) were improved by 8W (42 ± 23) (p < .001). The FCs in α and β bands calculated between the electrodes in the ipsi-lesional hemisphere were correlated negatively with the FMA score at 4W after stroke. The FCs obtained at 4W could be used to predict the FMA score at 8W after stroke.Conclusions: The FCs recorded at rest, as well as during the finger motor task, by the five electrodes placed on motor-related areas could be used to predict the motor function and recovery of the upper limb affected by stroke. The results indicate the possibility of using FCs recorded by conventional EEG with electrodes as biomarkers to predict motor recovery after stroke.

C4F7N is one of the most promising candidate to replace SF6 as arc quenching medium. Some buffer gases (N2 and CO2) are usually mixed with C4F7N to reduce the operating temperature. In order to provide priori knowledge of the arc quenching performance for C4F7N mixtures, the plasma properties including equilibrium compositions, thermodynamic properties, transport coefficients, and net emission coefficients of C4F7N–N2 and C4F7N–CO2 arc plasmas are calculated and the effects of buffer gases are discussed. Taking these properties as input, a 1D arc decaying model is constructed to describe arc decaying characteristics. According to the evolution of axial temperature and arc conductance over time, the arc decaying process is divided into three stages, i.e. the thermal recovery stage, the pre-dielectric recovery stage, and the post-dielectric recovery stage. We focus on the first two stages and describe them by the thermal recovery time (or rate) and the pre-dielectric recovery time (or rate) respectively. According to the results of 1D arc decaying modelling, the descending order of the thermal recovery ability for the gases studied in this work is: SF6 > C4F7N > 75%C4F7N–25%N2 > 75%C4F7N–25%CO2 > 50%C4F7N–50%N2 > 25%C4F7N–75%N2 > 50%C4F7N–50%CO2 > CO2 > 25%C4F7N–75%CO2 > N2; and the pre-dielectric recovery ability is: N2 > SF6 > CO2 > 25%C4F7N–75%CO2 > 25%C4F7N–75%N2 > 50%C4F7N–50%CO2 > 75%C4F7N–25%CO2 > 50%C4F7N–50%N2 > 75%C4F7N–25%N2 > C4F7N.

En este artículo describimos y analizamos procesos de recuperación de empresas desarrollados en el período 2000 – 2015. Transcurridos veinte años de las primeras recuperaciones de empresas, interesa especialmente analizar y caracterizar procesos que han logrado sostenerse con relativa estabilidad durante un período que aquí consideramos que ha traspuesto el de la estricta recuperación (etapa fundacional e incipiente recuperación). Así, centrándonos en la fase de consolidación de los procesos, nos preguntamos por las características de las formas económicas y las relaciones sociales que efectivamente se han consolidado en los procesos analizados, y por la naturaleza y los alcances de las transformaciones que en ambos (formas económicas y relaciones sociales) han tenido lugar. Todo ello, nos acerca a conocer si las nuevas configuraciones laborales constituyen una experiencia de trabajo socialmente distinta. In this article we describe and analyze recovery processes of companies developed in the period 2000 - 2015. Twenty years after the first recoveries of companies, it is particularly interesting to analyze and characterize processes that have managed to maintain themselves with relative stability during a period that we consider here transposed the one of the strict recovery (foundational stage and incipient recovery). Thus, focusing on the consolidation phase of the processes, we ask ourselves about the characteristics of the economic forms and social relations that have been effectively consolidated in the analyzed processes, and about the nature and scope of the transformations that both economic and social relations) have taken place. All this brings us closer to knowing if the new work configurations constitute a socially different work experience.

This paper analyses the effects that public credit guarantees have on SME business activity and investment. We focus the study on the main regional mutual guarantee institution in the Spanish Region of Madrid, covering two distinct stages of the economic cycle and credit environments: first, the full range of the country’s financial crisis with credit constraints (2009–2011), and later, the recovery stage with credit expansion (2012–2015). Using propensity score matching based on economic activity and company size, we show that guarantees allow for the relaxation of credit constraints, driving turnover and investment during both recession and growth. We also find that mutual guarantee schemes constituted a greater stimulus for firms during contraction; thus, they can act as countercyclical policies. Moreover, although guarantees had a substantial effect on all small companies (those with fewer than 50 employees), they had the greatest impact on microenterprises (those with fewer than 10 employees). We show the activities for which guarantees constitute a greater boost, which may inform public-policy designs for specific types of business.

In this paper, the thermoelectric power of hypo/hyper-eutectic Al-Si alloys melt induced by electromagnetic fields has been researched, as well as the resultant microstructures evolution corresponding to different stages of thermoelectric power. The results show that the thermoelectric power of Al-Si alloy melt is strongly sensitive to electromagnetic field, showing the sharp increment. Then thermoelectric power gradually gets back to the initial value after turning off the electromagnetic field. As for the resultant microstructures during the recovery stage of the thermoelectric power, TEM are used to capture the results that smaller Si particles grow up from the combination of Si particles after treatment. SEM observation and statistical processing data results about phase size/distribution show the recovery of eutectic Si phases, as well as the α-Al phases, indicating the pseudo growth of Si and Al clusters. Further, a recovery trend of primary Si phases also indicates the pseudo growth of Si clusters. Pseudo growth of clusters is verified by both the thermoelectric power and the resultant solidification microstructures. The recovery solidification microstructures correspond well to the thermoelectric power decrement after treatment.

ObjectiveThe purpose of this study was to investigate the diagnostic performance of serum CK-MB, TNF-α and hs-CRP in children with viral myocarditis (VMC).MethodsFifty-six children with confirmed diagnosis of VMC were included in this study. Of the included 56 cases, 25 subjects were in acute and other 31 were in the recovery stage. A contemporaneous control group of 22 children were included for comparison. The serum concentration of CK-MB, TNF-α and hs-CRP were examined in both VMC and control groups.ResultsThe serum concentration of CK-MB, TNF-α and hs-CRP were 31.77±9.48 (UL), 143.11±23.27 (ng/L) and 8.10±1.94(mg/L) for acute stage VMC; 12.72±4.99 (UL), 83.15±13.35 (ng/L) and 4.07±1.12 (mg/L) for recovery stage VMC; 8.11±3.20 (UL), 68.27±12.55 (ng/L) and 2.56±1.27 (mg/L) for control group respectively; The serum concentration of CK-MB, TNF-α and hs-CRP were significantly different between acute stage VMC, recovery stage VMC and control groups (pConclusionSerum concentration of CK-MB, TNF-α and hs-CRP in children with VMC were significant increased especially in acute stage, which can be used as biomarkers for VMC diagnosis.

The service performances of asphalt pavement, especially rutting, will be inevitably affected by climate change. However, existing studies have generally focused on the rutting depth and rutting life, and thus became insufficient for comprehensively evaluating the influence of climate change on rutting over the service life. A resilience assessment method for asphalt pavement rutting is developed to solve the above problem. First, the original resilience method is extended to fit the system whose performance level continues to decline. Then, the calculation formulas of rutting resilience are derived by combining the rutting prediction model and the level assessment model. Subsequently, the influence degrees of climate change in representative cities on rutting resilience are studied. The results suggest that neglecting climate change in rutting design of asphalt pavement will lead to insufficient resilience, especially in northern China. Furthermore, the predicted temperature under RCP8.5 should be employed for asphalt pavement design.
