Antenna Phase Error Compensation for Terahertz Coded-Aperture Imaging

Coded-aperture antenna plays an important role in terahertz coded-aperture imaging radar system. However, the performance of a system is inevitably affected by the phase errors introduced by the coded-aperture antenna elements. In this paper, we propose a phase error compensation method by deducing a formula to compute all element phase errors accurately. According to the formula, the phase errors can be calibrated by using a calibrator and can be used to compensate the imaging model of the system. Numerical simulations demonstrate that the proposed method can effectively improve the imaging quality when the elemental phase error exceeds 10 ∘ .
External Breaking Vibration Identification Method of Transmission Line Tower Based on Solar-Powered RFID Sensor and CNN

This paper proposes an external breaking vibration identification method of transmission line tower based on a radio frequency identification (RFID) sensor and deep learning. The RFID sensor is designed to obtain the vibration signal of the transmission line tower. In order to achieve long-time monitoring and longer working distance, the proposed RFID sensor tag employs a photovoltaic cell combined with a super capacitor as the power management module. convolution neural network (CNN) is adopted to extract the characteristics of vibration signals and relevance vector machine (RVM) is then employed to achieve vibration pattern identification. Furthermore, the Softmax classifier and gradient descent method are used to adjust the weights and thresholds of CNN, so as to obtain a high-precision identification structure. The experiment results show that the minimum sensitivity of the proposed solar-powered RFID sensor tag is −29 dBm and the discharge duration of the super capacitor is 63.35 h when the query frequencies are 5/min. The optimum batch size of CNN is 5, and the optimum number of convolution cores in the first layer and the second layer are 2 and 4, respectively. The maximum number of iterations is 10 times. The vibration identification accuracy of the proposed method is over 99% under three different conditions.
The plasma proteome and acute phase proteins of broiler chickens with gait abnormalities

The acute phase response (APR) is the early and non-specific systemic reaction of the innate immune system to homeostatic disturbances. Pro-inflammatory cytokines and chemokines released from macrophages, monocytes and infected and damaged tissues affect the synthesis and secretion of hepatocytic proteins and drastically alter the plasma protein profile. Plasma proteins that change concentrations as a result of an APR are termed acute phase proteins (APPs). The measurable changes in APP concentrations during infectious, inflammatory, stressful, traumatic or neoplastic events are often proportional to the severity of the event(s). As such APP measurements are used as disease biomarkers and for prognostication.
Role of Composite Phase Change Material on the Thermal Performance of a Latent Heat Storage System: Experimental Investigation

Paraffin wax is a perfect phase change material (PCM) that can be used in latent heat storage units (LHSUs). The utilization of such LHSU is restricted by the poor conductivity of PCM. In the present work, a metal foam made of aluminium with PCM was used to produce a composite PCM as a thermal conductivity technique in PCM-LHSU and water was used as heat transfer fluid (HTF). An experimental investigation was carried out to evaluate the heat transfer characteristics of LHSU using pure PCM and composite PCM. The study included time-dependent visualization of the PCM during the melting and solidification processes. Besides, a thermocouple network was placed inside the heat storage to record the temperature profile during each process. Results showed that better performance could be obtained using composite PCM-LHSU for both melting and solidification processes. The melting time of composite PCM-LHSU was about 83% faster than that of a simple PCM-LHSU, and the percentage decreasing in the solidification time was about 85% due to the provision of metal foam.

Study the association between platelets count and grades of oesophageal varies in patients of cirrhosis of liver with portal hypertension

Background: cirrhosis of liver is a diffuse process of fibrosis that converts the liver architecture into structurally abnormal nodules Portal hypertension leads to dilatation of portal vein, splenomegaly, and formation of portal systemic collaterals at different sites. Screening endoscopy is recommended for early detection of esophageal varices (EVs) in cirrhotic patients with portal hypertension. However, this approach is limited by its invasiveness and cost. The aim of the study was to determine if platelet count can predict the presence of EVs, especially large (grade III, IV) EVs in need of prophylactic therapy. Methods: Statistically 100 patients previously or newly diagnosed with cirrhosis of liver with portal hypertension without history of hepatic encephalopathy, variceal bleeding, EVL, use of beta blockers, were selected for the study. Ultrasonography was performed in all cases to note the spleen size. Routine blood testing including platelet count was done and UGI-Endoscopy was done to detect presence of varices with grades. Statistical Analysis: Statistical analysis was done using Statistical Package for Social Survey (SPSS) for Windows version 17.0. The data obtained was analysed using mean, SD, Student’s t-test and chi square correlation coefficient, p value <0.05 was considered significant. Results: Among 100 patients studied ,90% patients were found to have esophageal varices. Based on endoscopic grading, incidence of grade 2 and grade 3 esophageal varices predominated, accounting to 48% and 23 % respectively. On correlation of platelet count with grades of esophageal varices it was evident that 44 patients had their platelet count less than 1 lac out of which 24 patients had grade 2 varices followed by 14 patients with grade 3 varices, p value <0.001 and was highly significant. Conclusions: The study depicts that with decrease in platelets count the chances of formation of higher grades of oesophageal varices increases and also a positive association exists.
Electron trapping in strong-field dissociative frustrated ionization of CO molecules

We experimentally investigate the laser-induced dissociative frustrated multiple ionization of CO molecules; in this process one of the released electrons does not escape to the continuum but is eventually trapped into highlying Rydberg states of the outgoing positively charged nuclear fragments at the ends of the laser pulse, leading to the formation of neutral Rydberg fragments, i.e., C∗ or O∗. By measuring the ejected neutral Rydberg and ionic nuclear fragments as well as the freed electrons in coincidence, we trace the probability of electron trapping by different nuclear fragments and find that formation of C∗ is preferred to O∗. Furthermore, the electron trapping to one of the outgoing nuclear fragments of the breaking molecule can be steered by using a phase-controlled two-color laser pulse. Our results show that Rydberg fragments are more likely to be produced for CO molecules when they are exposed to a laser field pointing from C to O. This orientation-dependent asymmetric emission of the neutral Rydberg fragments is further confirmed in the multiple ionization of CO molecules by using a single-color elliptically polarized femtosecond laser pulse.
Japanese Species of the Myrmecophilous Genus Thiasophila Kraatz, 1856 (Coleoptera, Staphylinidae, Aleocharinae)

Faunistic investigation of Japanese myrmecophiles revealed the occurrence of three new species of the genus Thiasophila Kraatz, 1856, which are described herein: T. nipponica sp. nov. (host: Lasius (Dendrolasius) sp. ; from Hokkaidô and Honshû), T. aynumosir sp. nov. (host: Formica truncorum; from Hokkaidô), T. shinanonis sp. nov. (host: F. yessensis; from Honshû). The two species of Thiasophila recorded from Japan prior to this work appear not to belong to this genus. A key to the Japanese species is provided.
Recruitment, habitat selection and larval photoresponse of Paraleucilla magna (Porifera, Calcarea) in Rio de Janeiro, Brazil

Little is known about the recruitment and behaviour of sponge larvae, especially of the class Calcarea. The calcareous sponge Paraleucilla magna is very common in Southeast Brazil, where it is considered a cryptogenic species. This study quantified recruitment rates in shaded and illuminated habitats for 2 years in Rio de Janeiro, Brazil, and analyzed larval photoresponses of this species. Four structures, each containing a shaded and an illuminated surface, were exchanged every 3 months for 2 years. The number of recruits was quantified on each plate. In the laboratory, larvae of P. magna were placed in halfshaded Petri dishes and the number of settlers in each side was counted after 24 h. Paraleucilla magna recruited continuously throughout the experiment. Recruits occurred in greater abundance on shaded surfaces than on illuminated surfaces, and the larvae were negatively phototactic in vitro. Despite the possible influence of other factors in the recruitment of sponges (such as sedimentation, competition and predation), the prevalence of P. magna in shaded habitats may also be related to larval choice.
Can One Reinforce Investments in Renewable Energy Stock Indices with the ESG Index?

Studies on the environmental, social, and governance (ESG) index have become increasingly important since the ESG index offers attractive characteristics, such as environmental friendliness. Scholars and institutional investors are evaluating if investment in the ESG index can positively change current portfolios. It is crucial that institutional investors seek related assets to diversify their investments when such investors create funds in the renewable energy sector, which is highly related to environmental issues. The ESG index has proven to be a good investment choice, but we are not aware of its performance when combined with renewable energy securities. To uncover this nature, we investigate the dependence structure of the ESG index and four renewable energy indices with constant and time-varying copula models and evaluate the potential performance of using different ratios of the ESG index in the portfolio. Criteria such as risk-adjusted return, standard deviation, and conditional value-at-risk (CVaR) show that the ESG index can provide satisfactory results in lowering the potential CVaR and maintaining a high return. A goodness-of-fit test is then used to ensure the results obtained from the copula models.
Gender-related Differences in Correlations among BMI, Salivary Testosterone and Cortisol and Depression and Alexithymia Scores in University Students

Introduction: Women have high anxiety and depression incidence compared to men. In the present study, gender-related differences in correlations among BMI, salivary testosterone and cortisol and depression and alexithymia scores in university students. Methods: A total of 88 Nigerian university students were involved in the study. Participants were 20 men and 68 women who were 17-25 years of age. Salivary assay of cortisol and testosterone were done using Enzyme-linked Immunosorbent Assay Kits. The Self-Reporting Questionnaire (SRQ) 20 adapted from WHO was used to screen for depression. Toronto Alexithymia Scale was used to assess the points associated with alexithymia. Results: In the present study, there was a significant negative correlation between testosterone and depression in only men, but not in the total sample and women. There were significant positive correlations between depression and alexithymia scores in the total sample and women, but not in men. Discussion: The gender difference in the relation of salivary testosterone with depression showed again that gender is a very important factor in behavioral studies including depression. It can be stated that testosterone can be an important hormonal factor to prevent or decrease depression or depressive thoughts in men but not in women. The positive correlations between depression and alexithymia scores suggest that high depression in female university students is related to social and environmental factors, but not low testosterone. Conclusion: These results suggest that high depression in female healthy university students is may be due to social, cultural, and ecological factors, but not hormonal (cortisol and testosterone) factors.
The significance of apomixis in the evolution of the angiosperms: a reappraisal

Apomixis, the ability to produce asexual seeds, constitutes, along with outcrossing and selfing, one of the three major breeding systems in the angiosperms. However, apomixis is by far the least common of these three, despite theoretical advantages of apomixis over outcrossing and selfing. Darlington and Stebbins argued more than 50 years ago that no completely apomictic (sub)genera exist within the angiosperms. Clones lack genetic variation and therefore the ability to adapt to changing environments. In addition it has been suggested that clones degenerate because of the accumulation of deleterious mutations. The commonly held view is therefore that apomicts are evolutionary dead ends, doomed to early extinction. Recent genetic studies provide insight in the genetic architecture of apomixis. Apomixis appears to be a genetically complex trait and may therefore be difficult to evolve. Recent progress in angiosperm phylogeny allows for the optimisation mapping of apomixis onto phylogenetic trees. Assuming that aposporous and diplosporous apomixis are non-homologous, the results indicate that gametophytic apomixis arose many times in the history of the angiosperms. Gametophyic apomixis is especially common in the Poaceae, the Asteraceae and the Rosaceae and its phylogenetic distribution is illustrated here within the former two. In both families apomixis is clustered at the (sub)tribal level, i.e. above the genus level. It is argued that some clades may be preadapted in such a way that apomixis evolves more easily, leading to parallel/convergent evolution of the trait. In addition, it now becomes clear that genes that encode for apomixis can be transmitted through pollen in hermaphrodites. In this way apomixis-genes can escape from early extinction and survive for longer periods of evolutionary time. The clustering of apomixis at the (sub)tribal level could then be due to a common ancestry or introgression of such apomixis-genes.
Analysing the role of citizens in urban regeneration: bottom-linked initiatives in Barcelona

ABSTRACT This article analyses recent urban regeneration projects in Barcelona, focusing especially on the role of bottom-up practices and their consideration and inclusion in urban regeneration policies. In a context of social and political mobilisation against austerity, the combination of these two elements gives rise to the emergence of bottom-linked practices and new policy instruments. Our comparison of two case studies in Barcelona shows that a process of experimentation for broadening urban regeneration is underway, but also that it is far from being consolidated and that it is not without its own contradictions.
Readapting Propp's Character Archetypes to Explore the Relational Dimension of City Data: A Design-oriented Approach

This paper presents the approach and tools created to critically investigate the roles and relationships among city stakeholders regarding data-related processes, in order to inform future design solutions for open data portals. The approach to explore the relational dimension of data in local activities is based on mapping the operational roles of the organizations involved in the city data ecosystem throughout a set of archetypes readapted from the characters found in Propp's theory on the narrative structure. A probes toolkit associated with storytelling techniques helped to test the proposed approach during a workshop organized in the city of Milton Keynes. The authors present their motivations and constraints, as well as the rationale regarding the definition of the approach and the construction of the toolkit as part of a design-oriented strategy of inquiry, and discuss the insights gained in the testing experience.
Out of Sync: Nonverbal Synchrony in Social Anxiety Disorder

We examined nonverbal synchrony during opposite-sex interactions of individuals with social anxiety disorder (SAD). Participants were 156 individuals: 38 diagnosed with SAD and 118 individuals who were not socially anxious (NSA). Participants formed 78 dyads of either 2 NSA individuals (control dyads; n = 40) or 1 individual with SAD and 1 NSA individual (SAD dyads; n = 38). Dyads were randomly assigned to either a closeness-generating conversation or a small-talk conversation, and nonverbal synchrony was derived from computer analysis of videos. We found that for control dyads, closeness-generating conversations led to increased nonverbal synchrony compared with small-talk conversations but did not find the same outcome in SAD dyads. We also found a positive association between social anxiety and nonverbal synchrony in small-talk conversations but a negative association in closeness-generating conversations. Thus, we found evidence for impaired nonverbal synchrony in SAD using objective measures. Implications for psychopathology and treatment are discussed.
Mapping candidate genes in Eucalyptus

We used the single-strand conformation polymorphism (SSCP) technique to map six genes on Eucalyptus urophylla and Eucalyptus grandis linkage maps. These included four genes involved in the common phenylpropanoid pathway (Caffeic acid 3-O-methyltransferase, Caffeoyl CoA 3-O-methyltransferase, 4-Coumarate CoA ligase and phenylalanine ammonia-lyase), two genes involved in the "lignin specific" pathway (Cinnamoyl CoA reductase and Cinnamyl alcohol dehydrogenase). The placement of these genes on the Eucalyptus maps was carried out using an interspecific hybrid mapping population. This will further facilitate the identification or exclusion of "positional" candidate genes for characterizing quantitative trait loci (QTL) for traits related to wood quality. We have studied colocations between these candidate genes and QTL for longitudinal growth strain and wood density. The 4-coumarate CoA gene seems to be a good candidate for wood density as measured by pilodyn. (Texte integral)
An Optimal Slip Ratio-Based Revised Regenerative Braking Control Strategy of Range-Extended Electric Vehicle

The energy recovered with regenerative braking system can greatly improve energy efficiency of range-extended electric vehicle (R-EEV). Nevertheless, maximizing braking energy recovery while maintaining braking performance remains a challenging issue, and it is also difficult to reduce the adverse effects of regenerative current on battery capacity loss rate (Q loss,% ) to extend its service life. To solve this problem, a revised regenerative braking control strategy (RRBCS) with the rate and shape of regenerative braking current considerations is proposed. Firstly, the initial regenerative braking control strategy (IRBCS) is researched in this paper. Then, the battery capacity loss model is established by using battery capacity test results. Eventually, RRBCS is obtained based on IRBCS to optimize and modify the allocation logic of braking work-point. The simulation results show that compared with IRBCS, the regenerative braking energy is slightly reduced by 16.6% and Q loss,% is reduced by 79.2%. It means that the RRBCS can reduce Q loss,% at the expense of small braking energy recovery loss. As expected, RRBCS has a positive effect on prolonging the battery service life while ensuring braking safety while maximizing recovery energy. This result can be used to develop regenerative braking control system to improve comprehensive performance levels.
Racial Profiling: Past, Present, and Future?

It has been more than two decades since the introduction of the first bill in Congress that addressed racial profiling in 1997. Between then and now, Congress never passed legislation on the topic, but more than half the states passed laws and many police departments put anti-profiling policies in place to combat it. The research and data on racial profiling has grown markedly over the last twenty-plus years. We know that the practice is real (contrary to many denials), and the data reveal racial profiling’s shortcomings and great social costs. Nevertheless, racial profiling persists. While it took root most prominently as a tactic for finding drug couriers on interstate highways and in airports, law enforcement at many levels has made use of it to combat other problems, such as terrorism and illegal immigration. This article surveys the history of racial profiling and the various efforts to take it on, and the voluminous evidence that it fails to secure public safety even as it erodes public confidence in police. It ends with ideas for sharpening efforts to bring profiling under control.
Bir Mantık Problemi Olarak Paradoks

Paradoks, ilk bakista dogru olan bir ifade veya akil yurutme etkinliginin bir celiski olusturmasi, cikmaza suruklemesi ve durumun icinden cikilamaz bir hal almasidir. Paradoksal bir ifade ya da akil yurutme kendi icindeki bu cikmazini, kendi disinda bir aciklamaya yonelmeden ya da ek oncule ihtiyac duymadan cozememektedir. Bu nedenle paradoksal onermeler, 'ya dogru ya yanlis' olarak ifade edilebilecek bir durumu degil, 'ne dogru ne de yanlis' olarak belirlenebilecek mantiksal celiskiyi, karar verilemez hali ve cozumsuz durumlari gostermektedir. Dolayisiyla boylesi bir onermenin ya da akil yurutmenin paradoksalligi, cikmazlardan birinin secimiyle de cozulememektedir. Oyle ki paradoksal ifade; dogru kabul edildigi zaman yanlis, yanlis kabul edildigi zaman da dogru olmakta ve bu nedenle paradokslarda mantiksal manada zorunlu, acik secik ve kesin bir sonuca ulasilamamaktadir. Zira farkli bakis acilarina iliskin olarak paradoksal ifadeye verilen yanit da farklilik arz etmektedir. O nedenle paradoks, cozulemez bir sorun ve catiski olarak karsimizda durmaktadir. Iste bu cozumsuzlugun fark edilmesi, esasinda dusuncenin baslangic noktasinin fark edilmesidir. Zira sorunun cozumunden cok cozum yolunu aramak, farkli bakis acilari gelistirmek, felsefi gaye olarak yolun sonunda degil yolda olmak, tam da paradoksun temel pratigidir ve bu sekliyle paradoks, zihinsel bir dinamiktir. Bu sebeple calismamizin amaci, paradoksun ne oldugu, bir felsefi dusunceye katkisi ve bir mantik problemi olarak akli nasil bir cikmaza surukledigi uzerinde durmaktir.
