Performance analysis of bimodular simply supported beams based on the deformation decomposition method

Abstract A deformation decomposition method is proposed to study the basic deformation performance of bimodular simply supported beams, which is validated by the finite element method, the analytical solution of neutral axis height and the opening beam test. The proposed method can not only quantitatively identify tensile, compressive, bending and shear deformation of bimodular structures, but also visualize regions dominated by the above basic deformations. When the tensile-compression elastic modulus differs greatly, a composite beam phenomenon exists in bimodular simply supported shallow beams. Reducing the tensile-compression elastic modulus ratio of the material can make deep beams produce similar characteristics to shallow beams. Highlights A deformation decomposition method suitable for bimodular structures is proposed and validated by the finite element method, the analytical solution of neutral axis height and the opening beam test. The proposed method can not only quantitatively identify the tensile, compressive, bending and shear deformation, but also visualize the area dominated by the above basic deformation. When the elastic modulus of tension and compression differs greatly, a composite beam phenomenon exists in bimodular simply supported shallow beams. Properly reducing tensile-compression elastic modulus ratio of the material can make deep beams possess similar characteristics with shallow beams.
Study of Area-based Stereovision Method for Locating Tomato in Greenhouse

In this paper, stereovision was applied to locate tomatoes. After transformed to grayscale, the image was segmented with threshold and processed with morphological operation, and then the noises were removed. Tomato was recognized from background and the center of tomato was extracted for building region of interest. In terms of gray correlation of neighborhood regions, depths of the tomato surface points were calculated with area-based method. And the restriction of searching range in right image was used to reduce computation burden and improve precision. Then matching results were distinguished by twice thresholds. According to experiments, the error of depth ranged within ±10 mm when distance was below 450mm and the time of computation was less than 0.2 s.
Maternal diets affected ceramides and fatty acids in brain regions of neonatal rats with prenatal ethanol exposure

ABSTRACT Objectives: Ceramide (Cer), known as apoptotic markers, increases with prenatal ethanol (EtOH) exposure, resulting in neuroapoptosis. Whether maternal nutrition can impact Cer concentrations in brain, via altering plasma and brain fatty acid compositions have not been examined. This study compared a standard chow with a formulated semi-purified energy dense (E-dense) diet on fatty acid composition, Cer concentrations, and apoptosis in plasma and brain regions (cortex, cerebellum, and hippocampus) of pups exposed to EtOH during gestation. Methods: Pregnant Sprague–Dawley rats were randomized into four groups: chow (n = 6), chow + EtOH (20% v/v) (n = 7), E-dense (n = 6), and E-dense + EtOH (n = 8). At postnatal day 7, representing the peak brain growth spurt in rats, lipids, and apoptosis were analyzed by gas chromatography and a fluorometric caspase-3 assay kit, respectively. Results: Maternal E-dense diet increased total fatty acid concentrations (p < 0.0001), including docosahexaenoic acid (DHA) (p < 0.0001) in plasma, whereas DHA concentrations were decreased in the cerebellum (p < 0.03) of pups than those from chow-fed dams. EtOH-induced Cer elevations in the hippocampus of pups born to dams fed chow were reduced by an E-dense diet (p < 0.02). No significant effects of maternal diet quality and EtOH were observed on caspase-3 activity. No significant correlations existed between plasma/brain fatty acids and Cer concentrations. Discussions: Maternal diet quality affected fatty acid compositions and Cer concentrations of pups with prenatal EtOH exposure, differently. Maternal nutrition has the potential to prevent or alleviate some of the adverse effects of prenatal EtOH exposure.
Smart medical textiles with embedded optical fibre sensors for continuous monitoring of respiratory movements during MRI

We report on three respiration sensors based on pure optical technologies developed during the FP6 EU project OFSETH. The developed smart medical textiles can sense elongation up to 3%, while maintaining the stretching properties of the textile substrates for a good comfort of the patient. The sensors, based on silica and polymer fibre, are developed for monitoring of patients during MRI examination. The OFSETH harness allows a continuous measurement of respiration movements while all vitals organs are free for medical staff actions. The sensors were tested in MRI environment and on healthy adults.
Effects of Absolute Humidity on Flashover Voltage of Insulators

Effect of humidity on flashover voltage of four kinds of porcelain and one polymer insulators was studied experimentally for several years under natural humidity condition in Japan. It was found that the existing IEC humidity correction seems to be proper for most insulators regardless of the kind of applied voltage but that change may be necessary for pin type insulator under positive lightning impulse voltage application and for unit suspension disk and station post insulators under AC voltage application. Key-Words: Insulators, Flashover voltage, Absolute humidity, Humidity correction
Impact of Gender and Age on Claim Rates of Dread Disease and Cancer Insurance Policies in Taiwan

In this paper, the impact of both gender and age on the claim rates of dread disease and cancer insurance policies were examined using unique data taken from Taiwan’s private health insurance policies issued by non-life insurers during the 2012 to 2015 policy years. Those aged 30–39 served as the reference group. For the total number of dread disease policies, male insureds had a higher non-cancer claim probability than female insureds, while an age under 20 was associated with much lower claim rates for dread disease policies than for ages over 50. The claim rate for dread disease policies increased rapidly beginning at age 40 for both cancerous and non-cancerous diseases amongst male insureds. Amongst female insureds, those under 20 had much lower claim rates for dread disease policies. Only those aged 50–59 had a higher claim rate for non-cancerous diseases. For the total number of cancer insurance policies, male insureds had lower claim rates than female insureds, with an upward trend being associated with age. For male (female) insureds aged over 40 (20), the claim rates of cancer increased with age.
Minimax design of two-channel nonuniform-division FIR filter banks with -1, 0, and +1 coefficients

Utilizing an approximation scheme and a WLS algorithm, we present a method to design two-channel nonuniform-division filter (NDF) banks with continuous coefficients under the minimax criterion. It is shown that the optimal filter coefficients can be obtained by solving only linear equations. In conjunction with a proposed filter structure, a method is then presented to obtain the desired design result with filter coefficients taking on -1, 0, and +1 only. The effectiveness of the proposed technique is demonstrated by a simulation example.
PKMYT1 regulates the proliferation and epithelial-mesenchymal transition of oral squamous cell carcinoma cells by targeting CCNA2

Oral squamous cell carcinoma (OSCC) has gradually become a global public health issue in recent years. Therefore, the current study aimed to explore the mechanism of OSCC development and to identify a potential target that may be used in its treatment. The expression of protein kinase, membrane-associated tyrosine/threonine 1 (PKMYT1) and cyclin A2 (CCNA2) in SCC-9 cells was determined prior to and following transfection with short hairpin RNA targeting PKMYT1. Cell proliferation, colony-forming ability, migration and invasion were determined using Cell Counting Kit-8, colony formation, wound healing and Transwell assays, respectively. Furthermore, the expression of epithelial-mesenchymal transition (EMT)- and migration-related proteins were evaluated using western blot analysis. Additionally, co-immunoprecipitation was used to verify the binding of PKMYT1 and CCNA2. The results revealed that PKMYT1 was highly expressed in OSCC cells and that PKMYT1 knockdown could inhibit proliferation, colony formation, migration, invasion, EMT and CCNA2 expression in SCC-9 cells. In addition, PKMYT1 was demonstrated to bind to CCNA2, and knocking down PKMYT1 resulted in inhibitory effects on cell proliferation, colony formation ability, migration, invasion and EMT by downregulating CCNA2 expression. PKMYT1 was observed to regulate the proliferation, migration and EMT of OSCC cells by targeting CCNA2, which may be used in the future to improve OSCC treatment.

Temporal declines in Wadden Sea phytoplankton cell volumes observed within and across species

Cell size is a master trait in the functional ecology of phytoplankton correlating with numerous morphological, physiological, and life‐cycle characteristics of species that constrain their nutrient use, growth, and edibility. In contrast to well‐known spatial patterns in cell size at macroecological scales or temporal changes in experimental contexts, few data sets allow testing temporal changes in cell sizes within ecosystems. To analyze the temporal changes of intraspecific and community‐wide cell size, we use the phytoplankton data derived from the Lower Saxony Wadden Sea monitoring program, which comprises sample‐ and species‐specific measurements of cell volume from 1710 samples collected over 14 yr. We find significant reductions in both the cell volume of most species and the weighted mean cell size of communities. Mainly diatoms showed this decline, whereas the size of dinoflagellates seemed to be less responsive. The magnitude of the trend indicates that cell volumes are about 30% smaller now than a decade ago. This interannual trend is overlayed by seasonal cycles with smaller cells typically observed in summer. In the subset of samples including environmental conditions, small community cell size was strongly related to high temperatures and low total phosphorus concentration. We conclude that cell size captures ongoing changes in phytoplankton communities beyond the changes in species composition. In addition, based on the changes in species biovolumes revealed by our analysis, we warn that using standard cell size values in phytoplankton assessment will not only miss temporal changes in size, but also lead to systematic errors in biomass estimates over time.
Preliminary Evaluation of a Nuclear Scenario Involving Innovative Gas Cooled Reactors

In order to guarantee a sustainable supply of future energy demand without compromising the environment, some actions for a substantial reduction of CO2 emissions are nowadays deeply analysed. One of them is the improvement of the nuclear energy use. In this framework, innovative gas-cooled reactors (both thermal and fast) seem to be very attractive from the electricity production point of view and for the potential industrial use along the high temperature processes (e.g., H2 production by steam reforming or I-S process). This work focuses on a preliminary (and conservative) evaluation of possible advantages that a symbiotic cycle (EPR-PBMR-GCFR) could entail, with special regard to the reduction of the HLW inventory and the optimization of the exploitation of the fuel resources. The comparison between the symbiotic cycle chosen and the reference one (once-through scenario, i.e., EPR-SNF directly disposed) shows a reduction of the time needed to reach a fixed reference level from ∼170000 years to ∼1550 years (comparable with typical human times and for this reason more acceptable by the public opinion). In addition, this cycle enables to have a more efficient use of resources involved: the total electric energy produced becomes equal to ∼630 TWh/year (instead of only ∼530 TWh/year using only EPR) without consuming additional raw materials.
Design Patterns for Customizing Irrigation Governance

How can experience with good solutions for institutional design be shared in ways that help customize governance for diverse situations? In their pattern language for architecture and regional planning, Christopher Alexander and colleagues identified patterns, primarily based on successful vernacular architectures, which could be selectively combined and customized to fit particular situations. Similarly, institutional design patterns could be helpful in creating and adapting governance for commons. A semantic mediawiki could offer a useful platform for sharing design patterns, and collaborating to identify and develop design patterns, as part of the semantic web. Elinor Ostrom's design principles for commons, and principles for irrigation governance identified by Trawick illustrate design patterns useful for customizing irrigation governance.

Drug Legalization, Elite Support, and Government Effectiveness in Latin America

In Latin America, the legalization of drugs—where it occurred—has been driven mainly by elites, although much attention has been placed on public opinion. Considering that efforts toward legalization have been top-down, analysis should concentrate on opinions of the governing elites. To undertake such an analysis, we draw on data from surveys conducted in 18 Latin American parliaments (2012–2018), and we examine elite perspectives on the legalization of all drugs. Results from a Bayesian hierarchical logistic analysis show that in countries where the government is less effective, and where public health problems persist, legislators are less likely to support legalization. We argue that this is due to a lack of trust by MPs in legalization as a solution to trafficking. Wherever those concerned with drug trafficking see the current government as problematic, they will be less likely to support so challenging and complex a policy as drug legalization.
PLL Based on Self-Biased Techniques

Delay-Iorked loop (DLL) and phase-Iorked loop (PLJ") designs based upon self-biased techniques are presented. The DLL and PLL designs achieve process technology inde­ pendence, fixed damping factor, fixed bandwidth to operating frequency ratio, broad frequency range, input phase offset cancel­ lation, and, most importantly, low input tracking jitter. Both the damping factor and the bandwidth to operating frequency ratio areIetermined cmpletely by a ratio of capacitances, Self-biasing aVOids the necessity for external biasing, which can require special bandgap bias circuits, by generating all of the internal bias voltages and currents from each other so that the bias levels are eomJletely determined by the operating conditions. Fabricated in a 0.5-llm )V -well CMOS gate array process, the PLL achieves an operating frequency range of 0.0025 MHz to 550 MHz and input tracking jitter of 384 ps at 250 MHz with 500 m V of low frequency square wave supply noise.
More VCSELs at Finisar

In this paper we describe progress in moving VCSELs toward production-ready status in several applications, among others including substantially higher modulation speeds (14-25 Gbps, or even higher) than in current production. In addition we describe potential VCSEL failure mechanisms not previously published, as well as the limitations of some reliability testing techniques.
Computational Identification of Confirmatory Factor Analysis Model with Simplimax Procedures

Confirmatory factor analysis (CFA) refers to the FA procedure with some loadings constrained to be zeros. A difficulty in CFA is that the constraint must be specified by users in a subjective manner. For dealing with this difficulty, we propose a computational method, in which the best CFA solution is obtained optimally without relying on users’ judgements. The method consists of the procedures at lower (L) and higher (H) levels: at the L level, for a fixed number of zero loadings, it is determined both which loadings are to be zeros and what values are to be given to the remaining nonzero parameters; at the H level, the procedure at the L level is performed over the different numbers of zero loadings, to provide the best solution. In the L level procedure, Kiers’ (1994) simplimax rotation fulfills a key role: the CFA solution under the constraint computationally specified by that rotation is used for initializing the parameters of a new FA procedure called simplimax FA. The task at the H level can be easily performed using information criteria. The usefulness of the proposed method is demonstrated numerically.
Impact of Shyness on Self-Esteem: The Mediating Effect of Self-Presentation

Background: Although the relationship between shyness and self-esteem is well described in the psychological literature, far less is known about the potential mechanisms that underlie this association. The main goal of the current work is to verify whether self-presentation acts as a mediating variable between both constructs. Methods: The study was carried out among 198 adults. The Revised Cheek and Buss Shyness Scale, the Rosenberg Self-Esteem Scale, and the Self-Presentation Style Questionnaire were applied. Results: A large and positive correlation coefficient was observed between the following variables: (1) self-esteem/self-promotion; (2) shyness/self-deprecation. All other variables correlated negatively: (1) shyness/self-esteem; (2) shyness/self-promotion; (3) self-esteem/self-deprecation; (4) self-promotion/self-deprecation. Moreover, both self-promotion and self-deprecation acted as mediators between life satisfaction and self-esteem. Conclusion: The outcomes of the present study show a new mediating aspect for the direct relationship between shyness and self-esteem in the form of two styles of self-presentation. The results indicate that the tendency of shy people to avoid others can have a lower effect on their overall sense of self-esteem when they try to present themselves in a clearly favorable light. By contrast, shyness may have a stronger impact on their sense of self-worth when they present themselves as helpless, unsure, and incompetent.
Attitudes toward Applying Facial Recognition Technology for Red-Light Running by E-Bikers: A Case Study in Fuzhou, China

The application of facial recognition technology (FRT) can effectively reduce the red-light running behavior of e-bikers. However, the privacy issues involved in FRT have also attracted widespread attention from society. This research aims to explore the public and traffic police’s attitudes toward FRT to optimize the use and implementation of FRT. A structured questionnaire survey of 270 people and 94 traffic police in Fuzhou, China, was used. In the research, we use several methods to analyze the investigation data, including Mann–Whitney U test, Kruskal–Wallis test, and multiple correspondence analysis. The survey results indicate that the application of FRT has a significant effect on reducing red-light running behavior. The public’s educational level and driving license status are the most influential factors related to their attitudes to FRT (p < 0.001). Public members with these attributes show more supportive attitudes to FRT and more concerns about privacy invasion. There are significant differences between the public and traffic police in attitudes toward FRT (p < 0.001). Compared with the public, traffic police officers showed more supportive attitudes to FRT. This research contributes to promoting the application of FRT legitimately and alleviating people’s concerns about the technology.
