Thermotronics: Towards Nanocircuits to Manage Radiative Heat Flux

Abstract The control of electric currents in solids is at the origin of the modern electronics revolution that has driven our daily life since the second half of 20th century. Surprisingly, to date, there is no thermal analogue for a control of heat flux. Here, we summarise the very last developments carried out in this direction to control heat exchanges by radiation both in near and far-field in complex architecture networks.
Magnetic resonance coupling for 5G WPT applications

Inductive Wireless Power Transfer (IWPT) is the most popular and common technology for the resonance coupling power transfer. However, in 2007 it has experimentally demonstrated by a research group from Massachusets Institute of Technology (MIT) that WPT can be improved by using Magnetic Resonance Coupling Wireless Power Transfer (MRC WPT) in terms of the coupling distance and efficiency. Furthermore, by exploiting the unused, high-frequency mm-wave band which are ranging from 3~300 GHz frequency band, the next 5G generations of wireless networks will be able to support a higher number of devices with the increasing data rate, higher energy efficiency and also compatible with the previous technology. In this work, a square planar inductor with the dimension of 6.1 x 6.1 mm is designed, and the resonators have the same self-resonance frequency at 14 GHz. The coil resonators have been laid on Silicon and Oxide substrate to reduce the loss in the design. From the CST software simulation and the analytical model in MATLAB software, it has been shown that the MRC WPT design has improved the performance of IWPT design by 40% power transfer efficiency. MRC WPT design also has larger H-Field value which is 705.5 A/m, as compared to the IWPT design which has only 285.6 A/m when both Transmitter(Tx) and Reciever(RX) is at 0.3 mm coupling distance.
Diminishing the Threat: Reducing Intergroup Anxiety and Prejudice in Individuals Low in Openness to Experience

Author: Burrows, Dominique,. MS Institution: Purdue University Degree Received: May 2019 Title: Diminishing the Threat: Reducing Intergroup Anxiety and Prejudice in Individuals Low in Openness to Experience. Committee Chair: Leslie Ashburn-Nardo As the world continues to diversify and we begin to move towards a majority-minority America, it becomes ever critical for organizations to utilize diversity training effectively to create a more equitable work environment. This is especially true when considering the growth of Latino immigrants in the work force and how majority group members may view this as a threat to their group dominance, resulting in experiences of discrimination and prejudice towards minorities. However, research regarding the best methods to utilize to reduce prejudice against specific targeted groups has been inconclusive, and little work has been done to investigate personality characteristics as potential boundary conditions of diversity training effectiveness. Thus, the goal of this study is to investigate the effectiveness of two diversity training methods, perspective taking and imagined contact, specifically for trainees low in Openness to Experience who may be especially resistant to training. To test this over two time points (two weeks apart), we recruited White participants ( N= 471) via Amazon’s Mechanical Turk, highlighted the demographic changes occurring in the modern workforce, randomly assigned them to either the perspective taking, imagined contact, or control condition, and then measured their Openness to Experience, intergroup anxiety, prejudiced attitudes and behavioral intentions towards Latino immigrants. Results revealed no significant interactions with Openness to Experience, thus resulting in its omission from the final model. Results also did not provide evidence for the training methods having a significant direct effect on the reduction of prejudice and the increase in behavioral intentions towards Latino immigrants. However, there was support found for intergroup anxiety such that it mediated the relationship between the diversity training methods and prejudiced attitudes and behavioral intentions. Exploratory analyses also revealed imagined contact to be more effective at reducing prejudice and increasing positive behavioral intentions
The role of shape and texture information in sex classification

The sex of a face is perhaps its most salient feature. A principal components analysis (PCA) was applied separately to the three-dimensional structure and texture data from laser-scanned human heads. Individual components from both analyses captured information related to the sex of the face. Notably, single projection coe cients characterized complex structural di erences between three-dimensional male and female heads and between male and female texture maps. In a series of simulations, we compared the quality of the information available in the head versus texture data for predicting in the sex of the face. The results indicated that the three-dimensional structural data supported more accurate sex classi cation than the texture data, across a range of PCA-compressed (dimensionalityreduced) representations of the heads. This kind of dual face representation can give insight into the nature of the information available to humans for categorizing and remembering faces. The order of the rst two authors is arbitrary.

An extensive review of experimental ochratoxicosis in poultry: II. Hemato-biochemical and immunological alterations along with other health issues

Abstract Ochratoxins, primarily produced by certain species of Aspergillus and Penicillium are considered to be important threats for the health of poultry chicks. These fungal species are present as storage fungi within the stored feed ingredients and when they get proper growth requirements like aerobic condition coupled with high moisture contents lead to the production of ochratoxins as their secondary metabolites. In this second review of the series “An extensive review of experimental ochratoxicosis in poultry” OTA associated alterations in hematological, serum biochemical and immunological parameters have been addressed along with certain other important health issues associated with it in poultry.
Trans-Pacific transport and evolution of aerosols: spatiotemporal characteristics and source contributions

Abstract. Aerosols in the middle and upper troposphere have a long enough lifetime for trans-Pacific transport from East Asia to North America to influence air quality on the west coast of the United States (US). Here, we conduct quasi-global simulations (180∘ W–180∘ E and 70∘ S–75∘ N) from 2010 to 2014 using an updated version of WRF-Chem (Weather Research and Forecasting model fully coupled with chemistry) to analyze the spatiotemporal characteristics and source contributions of trans-Pacific aerosol transport. We find that trans-Pacific total aerosols have a maximum mass concentration (about 15 µg m−3) in the boreal spring with a peak between 3 and 4 km above the surface around 40∘ N. Sea salt and dust dominate the total aerosol mass concentration below 1 km and above 4 km, respectively. About 80.8 Tg of total aerosols (48.7 Tg of dust) are exported annually from East Asia, of which 26.7 Tg of aerosols (13.4 Tg of dust) reach the west coast of the US. Dust contributions from four desert regions in the Northern Hemisphere are analyzed using a tracer-tagging technique. About 4.9, 3.9, and 4.5 Tg year−1 of dust aerosol emitted from north Africa, the Middle East and central Asia, and East Asia, respectively, can be transported to the west coast of the US. The trans-Pacific aerosols dominate the column-integrated aerosol mass (∼65.5 %) and number concentration (∼80 %) over western North America. Radiation budget analysis shows that the inflow aerosols could contribute about 86.4 % (−2.91 W m−2) at the surface, 85.5 % (+1.36 W m−2) in the atmosphere, and 87.1 % (−1.55 W m−2) at the top of atmosphere to total aerosol radiative effect over western North America. However, near the surface in central and eastern North America, aerosols are mainly derived from local emissions, and the radiative effect of imported aerosols decreases rapidly. This study motivates further investigations of the potential impacts of trans-Pacific aerosols from East Asia on regional air quality and the hydrological cycle in North America.

A novelreverse phase liquid chromatographic methodwas developed and validated for estimation of chronic myelogenous leukemia and acute lymphocytic leukemia drug, imatinib mesylate in its API and dosage form i.e. tablets. The reverse phase HPLC analysis was carried out on isocratic system. The column was Peerless basic C18 (50mm x 4.6mm, 3μm) with ambient temperature. The mobile phase consisted of buffer: methanol in proportion 45: 55% (v/v). The flow rate was maintained at 1ml/min. The detection was carried out at wavelength 266 nm. The method was validated as per ICH guidelines for system suitability, linearity, accuracy and precision. The linear ranges was observed as 50–150μg/mlforimatinibmesylate. The accuracy and precision were found to be well within the acceptable limit. The method was successfully applied for assay imatinib mesylate of in API and dosage form with good recoveries.
Exponential H∞ filtering of networked linear switched systems with mode-dependent average dwell time: an event-triggered scheme

ABSTRACT In this paper, the event-triggered exponential filtering problem is addressed for a class of networked linear switched systems via mode-dependent average dwell time (MDADT) technique. An event-triggered communication mechanism is designed to enhance the resource utilisation in transmission and save the communication cost of systems as well. Then, the filtering error system is reconstructed as a switched time-delay system with bounded disturbance by virtue of the input delay system approach. By applying the mode-dependent Lyapunov functional approach, some interesting results with MDADT technique are derived to ensure the exponential stability and a prescribed disturbance rejection level. Further, some sufficient conditions for switched systems with average dwell time (ADT) are also presented as byproduct. An event-triggered exponential filter is presented by solving some convex optimisation problems. The efficiency of the presented results is verified through a numerical example and a PWM-driven boost converter systems.
School Relations and Solitude in Early Adolescence: A Mediation Model Involving Rejection Sensitivity

Rejection sensitivity (RS) is a cognitive and affective disposition to defensively expect, perceive, and overreact to signs of rejection by others. The current study examined the role of RS as a mediating mechanism underlying the relation between school relations with peers and teachers and solitude in early adolescence. Italian middle school students (N = 656; females = 50.9%; X ¯ age = 12 . 24 ) reported their RS, quality of relationships with their friends and teachers, peer-related loneliness, and attitudes toward aloneness. The results showed direct associations between school relations and RS components, as well as between RS and the three dimensions of solitude. Moreover, structural equation models showed that anxious RS and RS expectations, but not angry RS, mediated the association between school relations and solitude. The present study contributes to our understanding of the key mechanisms underlying the association between school relations and solitude.
I see you in me, and me in you

Purpose Based on the theory of crossover, the purpose of this paper is to explore the limited but growing body of research on positive crossover, wherein the authors investigated the direct and indirect crossover of work passion between the dyadic setting of leader and followers. The authors hypothesized that the leader’s (follower’s) work passion influence follower’s (leader’s) work passion through direct crossover phenomena (i.e. crossover via empathy). In the study, the authors also examined the underlying indirect crossover mechanism of leader’s (follower’s) work passion via personal identification – the process by which individuals (supervisors and subordinates) realize cognitive overlap between the self and other over time in a relationship. In an attempt to fully understand the crossover of leader’s (follower’s) work passion, the authors scrutinized the pattern of leader–follower relationship quality, which has the capacity to moderate the direct and indirect crossover of work passion from leader to follower and vice versa. Design/methodology/approach The authors conducted two independent studies and collected a time-lagged data from the dyadic settings of a large trade multinational company (n=77 supervisor and 373 subordinates) and a large manufacturing multinational company (n=89 supervisor and 411 subordinates) situated in Anhui province of China to test the authors’ moderated mediation model of work passion. Findings As expected the authors found support for all the authors’ hypothesized relationships. Specifically, the results provide support for the notion of direct and indirect crossover of work passion within leader–follower dyads. Moreover, the authors’ findings also support the moderated mediation model of direct and indirect crossover of work passion. Originality/value Overall, this study provides a potential way to stimulate work passion in employees (leader and followers) from the perspective of their relationship quality with each other. Moreover, implications for theory, research and practice with prospective future research topics are discussed.
Reconsidering the management paradigm of fragmented populations

Habitat fragmentation and population declines call for informed management of many endangered species. The dominant paradigm for such management focuses on avoiding deleterious inbreeding effects in separated populations, by facilitating migration to maintain connectivity between them, an approach epitomized by the “one migrant per generation” rule. We show that this paradigm fails to take into account two important factors. First, it ignores an inherent trade-off: maintaining within-population genetic diversity is at the expense of maintaining global diversity. Migration increases local within-population genetic diversity, but also homogenizes the meta-population, which may lead to erosion of global genetic diversity. Second, this paradigm does not consider that because many fragmented species have declined in numbers only within the last century, they still carry much of the high genetic diversity characteristic of the historically large population. The conservation of a species’ global diversity, crucial for evolutionarily adaptation to ecological challenges such as epidemics, industrial pollutants, or climate change, is paramount to a species’ long-term survival. Here we discuss how consideration of these factors can inform management of fragmented populations and provide a framework to assess the impact on genetic diversity of different management strategies. We also propose two alternative management strategies to replace the “one migrant per generation” dogma.
From Sound to Meaning: Representations of Speech in Human Cortex

Author(s): de Heer, Wendy Aileen | Advisor(s): Theunissen, Frederic E. | Abstract: This dissertation investigates the cortical representation of speech perception, using a combination of functional Magnetic Resonance Imaging (fMRI) and psychoacoustical experiments.Previous research has shown that low-level acoustical structure, phonemes, and words are processed by distinct cortical areas. However, little is known about the relationship between these different representations. To address this problem we simultaneously mapped many different representations of speech. We recorded fMRI responses from subjects listening to over two hours of natural speech. We then examined three features spaces representing the speech sounds in terms of auditory, articulatory and semantic features. We used voxel-wise modeling for each feature space combined with a novel variance-partitioning method to assess how much response variance could be explained uniquely by each model or jointly between two or three models. Validating our approach, we found that a quarter of the brain was significantly responsive to the stories, and that our models could account for up to 45% of the explainable variance in cortex and over 60% of the explainable variance in auditory areas. We also found a hierarchical set of processing steps starting in primary auditory areas and moving along the posteroventral region of the temporal lobe that are involved in the sound to word meaning transformation. The second part of this dissertation is a psychoacoustical investigation of the modulation power spectrum (MPS) of speech. The MPS is obtained by taking the 2-dimensional Fourier transform of the speech spectrogram. We showed that comprehension of vowels and consonants is differently affected by removal of specific spectral or temporal modulations. Supplementary consonant analysis showed differences in MPS and psychoacoustical comprehension results between three groups of consonants, separated based on the manner in which they are pronounced (fricatives, stops, and sonorants). The MPS could serve as an excellent intermediate step between lower and higher levels of speech processing, and could in future studies add nuance to our previous three cortical models of speech perception.
Novel mouse model of encephalocele: post-neurulation origin and relationship to open neural tube defects

ABSTRACT Encephalocele is a clinically important birth defect that can lead to severe disability in childhood and beyond. The embryonic and early fetal pathogenesis of encephalocele is poorly understood and, although usually classified as a ‘neural tube defect’, there is conflicting evidence on whether encephalocele results from defective neural tube closure or is a post-neurulation defect. It is also unclear whether encephalocele can result from the same causative factors as anencephaly and open spina bifida, or whether it is aetiologically distinct. This lack of information results largely from the scarce availability of animal models of encephalocele, particularly ones that resemble the commonest, nonsyndromic human defects. Here, we report a novel mouse model of occipito-parietal encephalocele, in which the small GTPase Rac1 is conditionally ablated in the (non-neural) surface ectoderm. Most mutant fetuses have open spina bifida, and some also exhibit exencephaly/anencephaly. However, a proportion of mutant fetuses exhibit brain herniation, affecting the occipito-parietal region and closely resembling encephalocele. The encephalocele phenotype does not result from defective neural tube closure, but rather from a later disruption of the surface ectoderm covering the already closed neural tube, allowing the brain to herniate. The neuroepithelium itself shows no downregulation of Rac1 and appears morphologically normal until late gestation. A large skull defect overlies the region of brain herniation. Our work provides a new genetic model of occipito-parietal encephalocele, particularly resembling nonsyndromic human cases. Although encephalocele has a different, later-arising pathogenesis than open neural tube defects, both can share the same genetic causation. Summary: Encephalocele is a severe congenital brain defect that arises after neural tube closure, but can share a common genetic cause with defects of cranial and spinal neural tube closure.
PROTEASES ASSOCIATED WITH Mycobacterium tuberculosis INFECTION

Tuberculosis is a contagious infectious disease caused by Mycobacterium tuberculosis, an obligate intracellular bacterium that relies on infection and host to host transmission to survive. In a co-evolution process, the pathogen developed virulence mechanisms to evade the host’s immune system and endure many factors, such as cellular stress for example. One of the strategies used by pathogens to achieve success in their infection is the production of proteases, which are enzymes that cleave peptide bonds between the amino acids in a protein. Proteases are widely distributed in the nature and have different roles that are considered important to the bacteria biological cycle. M. tuberculosis have several protease coding genes in its genome, many of which with unknown function, but several with attributed role in the infection process. This review presents the literature searched between 2014 and 2018 that addressed the roles of the proteases involved in the Mycobacterium tuberculosis infection.
Processed ground-motion records from induced earthquakes for use in engineering applications

We compile and process an electronic database of ground motions recorded on accelerometers and broadband seismographic instruments for induced earthquakes of M ≥ 4 at distances <50 km in central and eastern North America. Most of the data are from Oklahoma, with some records from Alberta. Our focus is on the subset of available records that are of most interest for engineering analyses aimed at evaluation of the potential hazards from induced events, which is a pressing issue in western Canada and other regions experiencing induced seismicity. We considered all records to 50 km for events of M ≥ 4.5. For events of M 4 to 4.5, we select records at close distance (<10 km), having good signal strength (PGA > ∼3%g), to allow high-quality time histories to be obtained. These records have strong signal-to-noise ratio, making them suitable for engineering applications, such as dynamic analysis, after proper scaling. The selected records are windowed, filtered, and instrument-corrected to compile a set of records having acceptable acceleration, velocity, and displacement time histories. The records and their response spectra are provided as an electronic supplement at http://www.seismotoolbox. ca/IS_Strong_Motions/ . We note that the record set is not suitable as a response spectra database for development of ground-motion prediction equations, because for M < 4.5 the record selection is biased to records with higher amplitudes. Rather, the intended use of the records is as seed records, which can be readily scaled in the time domain to approximately represent induced-event target scenarios for engineering applications.
