Abstract

Objective： This study aimed to solve the problems of yellowing, discoloration and quality preservation of broccoli after harvesting. Methods： Broccoli was fumigated with chlorine dioxide gas at different mass concentrations (0,0.2, 0.5, 1.0, 1.5, 2.0 mg/L) at 23 ℃, and the sensory, color, yelination grade, physiological and biochemical indexes and related browning enzyme activities of broccoli were determined after 0,2,4,6,8 days of storage. Results： Compared with the control group, different mass concentrations of ClO2 could inhibit the mass loss rate, yellowing browning and spoilage of flower buds of broccoli. ClO2 at 0.5 and 1.0 mg/L had a more significant effect on the maintenance of chlorophyll content, color difference a* and b*, and the inhibition of PPO and POD enzyme activities in broccoli. Among them, 0.5 mg/L ClO2 had the best effect on maintaining the color difference value of broccoli flower buds, and the yelination grade was still grade Ⅱ on the 8th day of storage. Simultaneously, it effectively maintained the vitamin C content and delayed the yelination and Browning of flower buds. Conclusion： It is necessary to control the concentration of ClO2 gas in the fumigation treatment of broccoli to obtain the best effect of maintaining the fresh green of broccoli bulbs and extending the shelf life.

Abstract

In order to meet the motion requirements of the elbow joint of the rehabilitation robot, a double-node symmetrical spiral corrugated elastic element is applied to the series elastic actuator (SEA), and the energy storage ratio is used as the optimization standard. Under the premise of the same quality,the maximum energy storage ratio can be achieved, which can better absorb the vibration of the mechanical arm and ensure the safety of the patient. Firstly, the three-dimensional modeling of the SEA is carried out. Then the torque spring is simulated and analyzed by using the finite element software, and the safety factor of the elastic unit is 2.37. Finally, the real object is processed. The experiment shows that the energy storage ratio can reach 9.63 J/kg, the measured stiffness kr is 264.04 N∙m/rad, the error of the simulated stiffness is 6.86%, and the torsion angle and torque of the elastic unit are linear and can be used for the flexible connection of the robotic arm, which lays the foundation for the further optimization of the robot, and also provides a technical verification method for solving such problems.

Abstract

Caries is a chronic infectious disease that occurs in the hard tissues of teeth. The interaction of oral microorganisms, host, food and time leads to the occurrence and progression of caries. Free sugar is an important food factor in the occurrence of dental caries. This paper reviews the research progress on the relationship between free sugar and caries in recent years, providing a reference for further clarifying the mechanism of the occurrence and progression of caries caused by free sugar and exploring the methods of caries prevention. The cariogenic mechanism of free sugar is multifaceted. Free sugar can not only be used by oral microorganisms in dental plaque biofilms to produce acid and synthesize intracellular and extracellular polysaccharides but also cause an imbalance in oral microecology and enhance gene expression related to the cariogenic toxicity of oral microorganisms. Based on the correlation between free sugar and caries, it is important to limit the intake amount and frequency of free sugar to prevent caries. This can be achieved mainly by formulating public health policies for reducing sugar, creating a low-sugar family environment with good eating habits, using sugar substitutes and using fluoride. There are few studies on the relationship between free sugar and oral microecology. More research is needed to better understand the effect of free sugar on oral microecology and its mechanism and to validate the caries-preventing effect of various sugar reduction measures. We believe such studies would open up new avenues for the effective prevention of caries.

Abstract

In an attempt to better understand structural benefits and generalization power of deep neural networks, we firstly present a novel graph theoretical formulation of neural network models, including fully connected, residual network (ResNet) and densely connected networks (DenseNet). Secondly, we extend the error analysis of the population risk for two layer network \cite{ew2019prioriTwo} and ResNet \cite{e2019prioriRes} to DenseNet, and show further that for neural networks satisfying certain mild conditions, similar estimates can be obtained. These estimates are a priori in nature since they depend sorely on the information prior to the training process, in particular, the bounds for the estimation errors are independent of the input dimension.

Abstract

The total production of global plastics is up to 400 million tons per year. Nearly 80% of the used plastics are directly landfilled or dumped in the environment, leading to the generation and release of microplastics, which poses a great threat to both environment and human health. How to recycle plastic waste efficiently and environmentally has become a common concern worldwide. Among the plastic waste recycling methods, chemical recycling such as pyrolysis can realize the transformation from polymer to high-value products. This paper summarizes the research and industrialization progress of four different plastic waste pyrolysis technologies, namely fast pyrolysis, catalytic pyrolysis, oxidative pyrolysis and hydro-pyrolysis. The challenges faced by the pyrolysis of plastic waste is discussed and the future development direction of various pyrolysis technologies is also outlooked. It is expected that some more efficient, environmentally friendly, and economical technologies of plastic waste pyrolysis can be explored in the future, to meet the growing demand for environmental protection and sustainable development.

145. Towards an Understanding of Residual Networks Using Neural Tangent Hierarchy (NTH)

Abstract

Gradient descent yields zero training loss in polynomial time for deep neural networks despite non-convex nature of the objective function. The behavior of network in the infinite width limit trained by gradient descent can be described by the Neural Tangent Kernel (NTK) introduced in \cite{Jacot2018Neural}. In this paper, we study dynamics of the NTK for finite width Deep Residual Network (ResNet) using the neural tangent hierarchy (NTH) proposed in \cite{Huang2019Dynamics}. For a ResNet with smooth and Lipschitz activation function, we reduce the requirement on the layer width $m$ with respect to the number of training samples $n$ from quartic to cubic. Our analysis suggests strongly that the particular skip-connection structure of ResNet is the main reason for its triumph over fully-connected network., Comment: 72 pages, 1 figure

Abstract

BackgroundA relatively high proportion of Asian American, Native Hawaiian, and Pacific Islander (AANHPI) females with lung cancer have never smoked. We used an integrative data approach to assemble a large-scale cohort to study lung cancer risk among AANHPIs by smoking status with attention to representation of specific AANHPI ethnic groups.MethodsWe leveraged electronic health records (EHRs) from two healthcare systems-Sutter Health in northern California and Kaiser Permanente Hawai'i-that have high representation of AANHPI populations. We linked EHR data on lung cancer risk factors (i.e., smoking, lung diseases, infections, reproductive factors, and body size) to data on incident lung cancer diagnoses from statewide population-based cancer registries of California and Hawai'i for the period between 2000 and 2013. Geocoded address data were linked to data on neighborhood contextual factors and regional air pollutants.ResultsThe dataset comprises over 2.2 million adult females and males of any race/ethnicity. Over 250,000 are AANHPI females (19.6% of the female study population). Smoking status is available for over 95% of individuals. The dataset includes 7,274 lung cancer cases, including 613 cases among AANHPI females. Prevalence of never-smoking status varied greatly among AANHPI females with incident lung cancer, from 85.7% among Asian Indian to 14.4% among Native Hawaiian females.ConclusionWe have developed a large, multilevel dataset particularly well-suited to conduct prospective studies of lung cancer risk among AANHPI females who never smoked.ImpactThe integrative data approach is an effective way to conduct cancer research assessing multilevel factors on cancer outcomes among small populations.
