Ocean colour is recognised as an Essential Climate Variable (ECV) by the Global Climate Observing System (GCOS); and spectrally-resolved water-leaving radiances (or remote-sensing reflectances) in the visible domain, and chlorophyll-a concentration are identified as required ECV products. Time series of the products at the global scale and at high spatial resolution, derived from ocean-colour data, are key to studying the dynamics of phytoplankton at seasonal and inter-annual scales; their role in marine biogeochemistry; the global carbon cycle; the modulation of how phytoplankton distribute solar-induced heat in the upper layers of the ocean; and the response of the marine ecosystem to climate variability and change. However, generating a long time series of these products from ocean-colour data is not a trivial task: algorithms that are best suited for climate studies have to be selected from a number that are available for atmospheric correction of the satellite signal and for retrieval of chlorophyll-a concentration; since satellites have a finite life span, data from multiple sensors have to be merged to create a single time series, and any uncorrected inter-sensor biases could introduce artefacts in the series, e.g., different sensors monitor radiances at different wavebands such that producing a consistent time series of reflectances is not straightforward. Another requirement is that the products have to be validated against in situ observations. Furthermore, the uncertainties in the products have to be quantified, ideally on a pixel-by-pixel basis, to facilitate applications and interpretations that are consistent with the quality of the data. This paper outlines an approach that was adopted for generating an ocean-colour time series for climate studies, using data from the MERIS (MEdium spectral Resolution Imaging Spectrometer) sensor of the European Space Agency; the SeaWiFS (Sea-viewing Wide-Field-of-view Sensor) and MODIS-Aqua (Moderate-resolution Imaging Spectroradiometer-Aqua) sensors from the National Aeronautics and Space Administration (USA); and VIIRS (Visible and Infrared Imaging Radiometer Suite) from the National Oceanic and Atmospheric Administration (USA). The time series now covers the period from late 1997 to end of 2018. To ensure that the products meet, as well as possible, the requirements of the user community, marine-ecosystem modellers, and remote-sensing scientists were consulted at the outset on their immediate and longer-term requirements as well as on their expectations of ocean-colour data for use in climate research. Taking the user requirements into account, a series of objective criteria were established, against which available algorithms for processing ocean-colour data were evaluated and ranked. The algorithms that performed best with respect to the climate user requirements were selected to process data from the satellite sensors. Remote-sensing reflectance data from MODIS-Aqua, MERIS, and VIIRS were band-shifted to match the wavebands of SeaWiFS. Overlapping data were used to correct for mean biases between sensors at every pixel. The remote-sensing reflectance data derived from the sensors were merged, and the selected in-water algorithm was applied to the merged data to generate maps of chlorophyll concentration, inherent optical properties at SeaWiFS wavelengths, and the diffuse attenuation coefficient at 490 nm. The merged products were validated against in situ observations. The uncertainties established on the basis of comparisons with in situ data were combined with an optical classification of the remote-sensing reflectance data using a fuzzy-logic approach, and were used to generate uncertainties (root mean square difference and bias) for each product at each pixel.

The use of clays for thermal treatments and cosmetic purposes continues to be a worldwide practice, whether through the preservation of native cultural traditions, pharmaceutical formulations or integrative health and well-being practices. Special clays, such as bentonites, are very common for healing applications due to their high cation exchange capacity (CEC), high specific surface area (SSA) and alkaline pH values and, therefore, are used in multiple therapeutic and dermocosmetic treatments. Numerous bentonitic deposits occur on Porto Santo Island with different chemical weathering degrees. This research evaluates which residual soils have the most suitable characteristics for pelotherapy. The texture of residual soils varies from silt loam to loamy sand and SSA between 39 and 90 m
2 /g. The pH is alkaline (8.7 to 9.6), electrical conductivity ranges from 242 to 972 µS/cm, and CEC from 50.4 to 86.8 µS/cm. The residual soils have a siliciclastic composition (41.36 to 54.02% SiO2 ), between 12.52 and 17.65% Al2 O3 and between 52 and 82% smectite content, which are montmorillonite and nontronite. Specific heat capacity (0.5–0.9 J/g°C) and cooling kinetics (14.5–19 min) show that one residual soil has the potential to be suitable for pelotherapy according to the literature. Moreover, the residual soils have As, Cd, Co, Cr, Hg, Mn, Ni, Pb, Sb and V concentrations higher than the limits of guidelines for cosmetics and pharmaceutical products.

A transcriptome-wide blood expression dataset of Parkinson's disease (PD) patients and controls was analyzed under the hypothesis-rich mathematical framework. The analysis pointed towards differential expression in blood cells in many of the processes known or predicted to be disrupted in PD. We suggest that circulating blood cells in PD patients can be in a full-blown PD-expression state. We put forward the hypothesis that sporadic PD can originate as a case of hematopoietic stem cell/differentiation process expression program defect and suggest this research direction deserves further investigation.

The architecture of the network of protein-protein physical interactions in Saccharomyces cerevisiae is exposed through the combination of two complementary theoretical network measures, betweenness centrality and `Q-modularity'. The yeast interactome is characterized by well-defined topological modules connected via a small number of inter-module protein interactions. Should such topological inter-module connections turn out to constitute a form of functional coordination between the modules, we speculate that this coordination is occurring typically in a pair-wise fashion, rather than by way of high-degree hub proteins responsible for coordinating multiple modules. The unique non-hub-centric hierarchical organization of the interactome is not reproduced by gene duplication-and-divergence stochastic growth models that disregard global selective pressures., Comment: Final, revised version. 13 pages.

Condensed Matter - Statistical Mechanics ,Condensed Matter - Disordered Systems and Neural Networks - Abstract
A central issue in complex networks is tolerance to random failures and intentional attacks. Current literature emphasizes the dichotomy between networks with a power-law node connectivity distribution, which are robust to random failures but fragile to targeted attacks, versus networks with an exponentially decaying connectivity distribution, which are less tolerant to failures but more resilient to attacks. We prove analytically that the optimal network configuration under a classic measure of robustness is altogether different from both of the above: in all cases, failure and/or attack, there are no more than three distinct node connectivities in the optimal network.

Nonlinear Sciences - Chaotic Dynamics - Abstract
We consider two linearly coupled masses, where one mass can have inelastic impacts with a fixed, rigid stop. This leads to the study of a two degree of freedom, piecewise linear, frictionless, unforced, constrained mechanical system. The system is governed by three types of dynamics: coupled harmonic oscillation, simple harmonic motion and discrete rebounds. Energy is dissipated discontinuously in discrete amounts, through impacts with the stop. We prove the existence of a nonzero measure set of orbits that lead to infinite impacts with the stop in a finite time. We show how to modify the mathematical model so that forward existence and uniqueness of solutions for all time is guaranteed. Existence of hybrid periodic orbits is shown. A geometrical interpretation of the dynamics based on action coordinates is used to visualize numerical simulation results for the asymptotic dynamics., Comment: 23 pages, 7 figures. Feedback welcome

A 45-year-old woman presented with sudden complete vision loss in her left eye and retroorbital pain worsened by eye movements. A previous milder episode of vision loss had occurred in the same eye 1 year before, with complete recovery after high-dose intravenous methylprednisolone. She had no light perception in the left eye with a swollen optic disc, but with a normal right optic disc. There were no systemic manifestations or infections. MR scan of the brain showed extensive enlargement and enhancement of the left optic nerve and optic chiasm. After excluding infections and autoimmune markers, a left optic nerve biopsy confirmed non-caseating granulomas, leading to a diagnosis of neurosarcoidosis. [ABSTRACT FROM AUTHOR]

- Abstract
A global in-situ data set for validation of ocean-colour products from the ESA Ocean Colour Climate Change Initiative (OC-CCI) is presented. This version of the compilation, starting in 1997, now extends to 2021, which is important for the validation of the most recent satellite optical sensors such as Sentinel 3B OLCI and NOAA-20 VIIRS. The data set comprises in-situ observations of the following variables: spectral remote-sensing reflectance, concentration of chlorophyll-a, spectral inherent optical properties, spectral diffuse attenuation coefficient and total suspended matter. Data were obtained from multi-project archives acquired via open internet services, or from individual projects, acquired directly from data providers. Methodologies were implemented for homogenisation, quality control and merging of all data. Minimal changes were made on the original data, other than conversion to a standard format, elimination of some points after quality control and averaging of observations that were close in time and space. The result is a merged table available in text format. Overall, the size of the data set grew with 151,673 rows, with each row representing a unique station in space and time (cf 136,250 rows in previous version; Valente et al., 2019). Observations of remote-sensing reflectance increased to 68,641 (cf 59,781 in previous version; Valente et al., 2019). There was also a near tenfold increase in chlorophyll data since 2016. Metadata of each in situ measurement (original source, cruise or experiment, principal investigator) are included in the final table. By making the metadata available, provenance is better documented, and it is also possible to analyse each set of data separately. The compiled data are available at https://doi.pangaea.de/10.1594/PANGAEA.941318 (Valente et al., 2022).

Argila ,Minerais argilosos ,Gabros de Beja ,Solos residuais ,Peloterapia - Abstract
Os efeitos terapêuticos e/ou cosméticos das argilas são amplamente reconhecidos e o seu uso é tão antigo como a própria humanidade. Têm sido utilizadas em vários países, em termas ou centros de talassoterapia, para tratar problemas reumatológicos, doenças de pele ou para fins cosméticos. Atualmente, o uso de geoprodutos para tratamentos é conhecido como Geoterapia. A Peloterapia é uma variante da Geoterapia e consiste no uso de argilas por via interna ou externa devido às suas propriedades: analgésica, anti inflamatória, cicatrizante, tonificadora, vitalizante e antitóxica. O presente trabalho tem como objetivo principal estudar oito amostras de solos residuais recolhidos na zona de Beja e averiguar se apresentam, ou não, características adequadas para a utilização em peloterapia. Realizaram-se diversos ensaios de caracterização granulométrica, mineralógica, físico-química e tecnológica dessas amostras de argilas. Entre os ensaios realizados para verificação da sua adequabilidade para peloterapia, selecionaram- se: granulométricos como curva granulométrica, sedigraph e superfície específica; mineralógicos por Difração de Raios X (DRX) de agregados orientados e não orientados; físico-químicos por Fluorescência de Raios X (FRX), matéria orgânica (MO), pH, condutividade, Capacidade de Troca Catiónica (CTC); e tecnológicos como tempo de arrefecimento, abrasividade, limites de consistência, expansibilidade, viscosidade, calor específico e absorção de óleo. As amostras Beja 3, Beja 21 e Beja 40 cumprem os valores mínimos aceitáveis para serem utilizadas em peloterapia, no entanto, sugere-se a elaboração de ensaios futuros com o intuito de averiguar se são prejudiciais para a saúde humana e maximizar os seus efeitos benéficos. The therapeutic and/or cosmetic effects of clays are widely recognized, and their use is as old as humanity itself. The use of clays in many countries, in spa or thalassotherapy centres, to treat rheumatological or skin problems or for cosmetic purposes is frequent. Geotherapy is the treatment with geoproducts. Pelotherapy is a variant of geotherapy and consists of the use of internal or external clays due to its properties: analgesic, anti-inflammatory, healing, toning, vitalizing and antitoxic. The main objective of this work was to study eight residual soil samples collected in the Beja region and to verify if they present or not suitable characteristics for use in pelotherapy. The author selected several laboratory tests to characterize the selected samples, such as particle size, mineralogical, physicochemical, and technological of these clay samples. Among these tests performed to verify its suitability for pelotherapy, the author selected the following: particle size such as particle size curve, sedigraph and specific surface; physicochemical by X-ray fluorescence (XRF), determination of organic matter (MO), pH, conductivity, Cation Exchange Capacity (CTC); mineralogical by X-ray Diffraction (XRD) of oriented and unoriented aggregates; and technological such as cooling time, abrasiveness, consistency limits, expandability, viscosity, specific heat and oil absorption. Beja 3, Beja 21 and Beja 40 samples meet the minimum acceptable values to use in pelotherapy, however, it is suggested that future trials be carried out to ascertain whether they are harmful to human health and maximize their beneficial effects.

Atherosclerosis is a chronic inflammatory cardiovascular disease, which results from lipid accumulation in the blood vessel wall, forming a plaque, and ultimately restricting blood flow. The immune system plays a vital role in progression to plaque rupture. While recent evidence clearly indicates the anti-inflammatory function of regular exercise, the mechanisms by which regular exercise can modulate its pathophysiology is not well understood. In this review, we discuss how regular exercise can lower systemic inflammation directly via modulation of the immune system or indirectly via altered myokine concentrations and metabolites. We describe the exercise-induced responses of various myokines (such as IL-6, adiponectin, and FGF21), and how cell function in the innate immune system can be modulated via regular exercise, with the aim to modulate plaque formation in atherosclerosis.

Este tipo de malha tem como principal característica ser formada apenas por cubos tal que a razão entre as arestas de dois volumes é sempre uma potência de dois. A possibilidade de ter pequenos volumes próximos a interfaces irregulares permite uma mais detalhada discretização. Além disto, regiões onde a propriedade do meio é constante podem ser representadas por volumes maiores, economizando-se assim memória e tempo. São construídos operadores diferenciais discretos gradiente e divergente, através da montagem de matrizes que conectam os volumes a suas faces e duas novas aproximações para o operador diferencial gradiente são desenvolvidas, visando-se elevar a ordem de aproximação original e minimizar reflexões numéricas em virtude da malha ser não conforme. A técnica proposta é aplicada e discutida em fenômenos governados pelas equações do calor e da onda, incluindo a modelagem de um tratamento para o câncer por hipertermia e a propagação de ondas acústicas em ambientes geológicos complexos. In order to better handle problems with complex domain, a numerical scheme with OcTree meshes based on the Finite Volume Method is developed in the present work. The main feature of this mesh with cube form is that the ratio between the edges of two volumes retains a power of two. The possibility of having small volumes adjacent to irregular interfaces leads to a more precise capture of interfaces. Regions with constant property can be represented by larger volumes, resulting in saving both memory and CPU time. On the other hand, in the case of the study of seismic waves, the use of larger volumes in regions with higher wave propagation velocity reduces significantly data storage and processing time. Differential discrete gradient and divergent operators are constructed through the assembly of matrices that connect the volumes to their faces. In addition, two new approaches to the differential gradient operator are developed, aiming at raising the original approximation order and minimizing numerical reflections by virtue of the nonconforming mesh. The proposed technique is applied and discussed to phenomena governed by the heat and wave equations with substantially great practical interest, including a modeling of a treatment for cancer by hyperthermia and of the propagation of acoustic waves in complex geological environments.

- Abstract
A global compilation of in situ data is useful to evaluate the quality of ocean-colour satellite data records. Here we describe the data compiled for the validation of the ocean-colour products from the ESA Ocean Colour Climate Change Initiative (OC-CCI). The data were acquired from several sources (including, inter alia, MOBY, BOUSSOLE, AERONET-OC, SeaBASS, NOMAD, MERMAID, AMT, ICES, HOT and GeP&CO) and span the period from 1997 to 2018. Observations of the following variables were compiled: spectral remote-sensing reflectances, concentrations of chlorophyll a, spectral inherent optical properties, spectral diffuse attenuation coefficients and total suspended matter. The data were from multi-project archives acquired via open internet services or from individual projects, acquired directly from data providers. Methodologies were implemented for homogenization, quality control and merging of all data. No changes were made to the original data, other than averaging of observations that were close in time and space, elimination of some points after quality control and conversion to a standard format. The final result is a merged table designed for validation of satellite-derived ocean-colour products and available in text format. Metadata of each in situ measurement (original source, cruise or experiment, principal investigator) was propagated throughout the work and made available in the final table. By making the metadata available, provenance is better documented, and it is also possible to analyse each set of data separately. This paper also describes the changes that were made to the compilation in relation to the previous version (Valente et al., 2016). The compiled data are available at https://doi.org/10.1594/PANGAEA.898188 (Valente et al., 2019).

Resumo Anastomoses vasculares são procedimentos comuns realizados por grande parte dos cirurgiões e cujo treinamento ocorre principalmente em seres humanos, contrariando os princípios éticos vigentes. Esse fato se deve, sobretudo, à carência e ao alto custo relacionados aos atuais modelos de treinamento. Assim, este estudo visa avaliar a viabilidade de três vegetais para a realização de anastomoses vasculares. Foram utilizadas cinco unidades de cebolinha, vagem e feijão-verde. Em cada uma tentou-se realizar uma anastomose término-terminal. Conseguiu-se a realização da anastomose apenas na vagem e no feijão-verde. Contudo, por apresentar uma menor espessura, o feijão-verde assemelhou-se mais aos vasos humanos. Abstract Vascular anastomoses are common procedures and are performed by most surgeons. Training is primarily conducted in human beings, which violates current ethical principles. This is because current training models are expensive and in short supply. This study was designed to investigate the feasibility of three vegetable models of vascular anastomosis. Five units each of scallions, green beans, and yardlong beans were used. An end-to-end anastomosis was attempted with each specimen. Anastomoses were only successful in green beans and yardlong beans. Since they are narrower, the yardlong beans are the most similar to human vessels.
