Role of uncertainty estimation in accelerating materials development via active learning

An active learning strategy using sampling based on uncertainties shows the promise of accelerating the development of new materials. We study the efficiencies of the active learning iteration loop with different uncertainty estimators to find the “best” material in four different experimental datasets. We use a bootstrap approach aggregating with support vector regression as the base learner to obtain uncertainties associated with model predictions. If the bootstrap replicate number B is small, the variance estimated by the empirical standard error estimator is found to be close to the true variance, whereas the jackknife based estimators give an upward or downward biased estimation of variance. As B increases, the bias of the jackknife based estimators decreases and the variance estimated finally converges to the true one. Therefore, the empirical standard error estimator needs the least number of iteration loops to find the best material in the datasets, especially when the bootstrap replicate number B is small. Our work demonstrates that an appropriate Bootstrap replicate B is conducive to minimizing calculation costs during the materials property optimization by active learning.
Factors Influencing Consumers’ Intention to Adopt Fashion Robot Advisors: Psychological Network Analysis

Drawing upon the theory of human–robot interaction (HRI), this study examined the relations among perceived characteristics of fashion robot advisors (FRAs), consumers’ negative preconceptions toward robots, and positive dispositions toward technology to identify network differences in adoption and nonadoption groups. For interviews, pretests, and main data collection, we presented video clips of FRAs as stimuli. Based on the data (n = 464) collected via an online survey, we conducted psychological network analysis to explore defining factors that differentiate adoption and nonadoption groups. The results indicate that perceived characteristics of social intelligence, humanlikeness, and knowledgeableness combined with a positive disposition of technological self-efficacy lead to adoption of FRAs. This study contributes to the literature on the theory of HRI and technology acceptance models, particularly in fashion retail sectors. Furthermore, this study provides a new graphical approach to networks that conceptualizes shoppers’ adoption of technology as a complex interplay of psychological attributes.

Numerical study of a new earth-air heat exchanger configuration designed for Sahara climates

Thermal performance for cooling and heating in the building can be achieved by the novel shape of the earth–air heat exchanger (EAHE). In a heavily populated area such as City, Due to the limited ground space. EAHE systems are rarely used, for most residential andcommercial utilization.This paper presents a numerical investigation of the thermal performance of a spiral-shaped configuration Spiral Earth to Air Heat Exchanger SEAHE intended for the summer cooling inhot and arid regions of Algeria. A parametric analysis of the SEAHE has been performed toinvestigate the effect of diameter, depth, pipe length and of airflow rate on the outlet air in theexchanger. Results show that the specific heat exchange is used to cool in an arid zone (south-east of Algeria). When the ambient temperature varies between 40°C and 45 °C, the coolingtemperature varies between 25°C and 29 °C. Temperature difference inlet and outlet airexchanger 18°C, these values are quite acceptable with for cooling the building.
Increase of free radical levels in the periodontal tissues of therapeutic dose radiation applied rats and potential protective effects of bioflavonoids and polyphenols (ENOANT®)

The aim of this study is to determine the effects of the therapeutic dose radiation application on the periodontal tissues of rats and to examine the protective effects of antioxidant application against free radicals prior to radiotherapy. 40 Wistar albino rats were divided into groups of ten animals each: radiotheraphy group; 20 days ENOANT® group; 1 day ENOANT® group, and control group. Then, 3 Gray (Gy) therapeutic dose radiation were applied to head and neck area of the rats outside the control group. After the application, Malondialdehyde (MDA) levels in serum and periodontal tissues were measured by Thiobarbituric acid (TBA) method in the radiotherapy group, long and short term ENOANT® used groups and the control group. The obtained values were statistically compared, the statistical analysis of obtained results showed that according to tissue MDA level, a significant degree of decrease was found in long term ENOANT® used group compared to the radiotherapy group (p LESS THAN 0,05). According to these the long-term use of ENOANT® is more effective than its short-term use.
Software-Defi Wireless Sensor Networks: A Systematic Review, Architecture and Challenges

Software-defined networking (SDN) paradigm leads to innovation and simplicity in network configuration and management. Wireless sensor networks (WSNs) are becoming an essential component of the Internet of Things (IoTs). The combination of these two models gives rise to a new paradigm: Software-defined wireless sensor networks (SDWSNs). This paper provides a systematic review on SDWSNs. The study also discusses open challenges of further research on SDWSNs.
The role of multiwall carbon nanotubes on physical, mechanical and rheological properties of poly(lactic acid)/natural rubber/CNT hybrid systems

The main objective of the present work was to study the role of carbon nanotube (CNT) on the microstructure development and physical, mechanical, and rheological properties of poly(lactic acid) (PLA)/natural rubber (NR)/CNT hybrid nanocomposites. The PLA/NR blend samples with constant blend ratio (90/10) were prepared by melt mixing in a laboratory internal mixer at a temperature of 190°C. The behavior of the PLA/NR blend was examined depending on the CNT content (0.5–6 wt%). The droplet size and droplet size distribution of the NR phase decreases with the increase in CNTs content. This could be explained in terms of compatibilizing effect of CNT and the changing of the viscosity ratio of the blend phases. The development of the microstructure and the physical properties of the blend were also investigated according to the CNT contents by measuring the linear viscoelasticity. The elongational behavior and mechanical properties of the blends were strongly dependent on the location of the CNT. The CNT worked as an efficient compatibilizer and also it worked as a reinforcing filler making the matrix more rigid.
“NO MATTER WHAT REHABILITATION OR TREATMENT YOU GET… THERE IS ALWAYS POSSIBILITY.”: AN EXAMINATION OF THE RISKS AND DANGEROUSNESS POSED BY CHILD SEX OFFENDERS FROM THE PUBLIC’S PERSPECTIVE.

Child sexual victimisation is considered as one of the most detrimental and seemingly ‘unforgiveable’ crimes against humans, which often results in these offenders becoming socially distant and commonly dehumanised, stigmatised, shamed and socially excluded in society. These horrendous crimes provoke negative attitudes from the community that reinforce the segregation between rehabilitating offenders and the community. Yet, it is the community that is a key component to any successful reintegration or rehabilitation in the community setting. To fully understand the complexities of public perception and the implications it has for criminological research and community-based reintegration efforts; it is necessary to understand the community’s perception of risks posed by these offenders. Also, to identify the characteristics that are associated with heightened perception of risk, suggest ways of bridging the gap between offender and the community to encourage successful re-integration, while identifying different lines of inquiry to reduce child sexual victimisation in the first instance. Reflecting upon a mixed methods approach to identify the public’s perception of risk using both an online questionnaire and semi-structured interviews, this paper draws upon the public’s preference to prevention tactics rather than intervention strategies within the community-setting. This paper calls for an alternative focus to crimes against children, its offenders and criminal justice responses to these atrocities. Prevention is better than intervention. We should invest in prevention methods similar to those in Germany and the Netherlands such as, self-referrals for individuals who acknowledge a problematic behaviour before it becomes a criminal offence.
Caracterización socio-económica de la cría de bovinos en la agricultura familiar del Alto Egipto

El Egipto actual es una entidad compleja, que enfrenta una lucha contra el crecimiento de la población y la pobreza en el camino hacia un desarrollo humano equitativo. Esto es particularmente cierto en el Alto Egipto, donde más de la mitad de la población rural se considera en situación de pobreza, siendo la agricultura familiar, y en particular la cría de bovinos, una de sus principales fuentes de ingresos. Para identificar los factores socio-económicos que influyen en los sistemas tradicionales de agricultura familiar dedicados a la cría de bovinos, así como evaluar los conocimientos, aptitudes y prácticas de los productores pecuarios del Alto Egipto, se diseñó un estudio basado en entrevistas individuales y colectivas realizadas en hogares seleccionados de las gobernaciones de Minya, Assiut, Sohag, Quena y Luxor. Los resultados muestran como la cría de bovinos en esta región se ve significativamente obstaculizada por el limitado acceso a la tierra, el alto costo y escasa disponibilidad de insumos básicos, la marcada estacionalidad de la productividad animal, unos servicios de extensión pecuaria insuficiente y la dificultad para acceder a créditos y préstamos. Además, las estrategias y programas de mejora genética nacionales han descuidado las razas bovinas autóctonas (Baladi), a pesar de ser consideradas por los productores más adaptadas y resistentes a las severas condiciones locales. La comprensión de estos factores es esencial para la formulación e implementación de estrategias de intervención destinadas a mejorar la calidad de vida de estas comunidades rurales, así como preservar y gestionar los recursos zoogenéticos bovinos que explotan.
ANGUISH: Security attack in narrowband‐Internet of Things (NB‐IoT) using game theory and hardware analysis

In recent years, the Internet of Things (IoT) plays a vital role in our daily life. IoT is dominating in many areas like industries, health care, smart home, social network, defense sector, and the education sector. In the last couple of years, users are facing different challenges like security issues related to social network and defense sector. In this article, our prime focus is to secure the social and defense network associated with narrowband‐Internet of Things. This article proposes the artificial intelligence (AI)‐based defense security attacks using unmanned aerial vehicle (UAV). In the first part of the article, we have proposed attack modeling on smart home scenario and finalize the critical parameter for performance analysis. In the next section, the performance analysis based on game theory (GT) (AI based) approach is attained, using different techniques like nash equilibrium and Prisoner's dilemma. In the last section, detailed hardware analysis has been carried out for analyzing attack in real‐time scenario and is illustrated with the help of step‐by‐step process. Our proposed model proves that UAV‐based router can spoof by the intruder with the probability of 0.4 using GT and hardware analysis.
The Influence of Magnetic Fields on Selected Physiological Parameters of Blood and Tissues in Mice

This study aimed to highlight the influence of exposure to different applied magnetic fields (MFs) on SOD, MDA and GSH levels in the liver, LDH and CPK activities in the muscle and γ-aminobutyric acid levels in the brain, as well as some haematological parameters. Adult male albino Swiss mice were divided into 5 equal groups (n = 6), the control group (untreated) and four exposure groups that were exposed to MFs of 20, 40, 60 and 80 Gauss for 5 min/day for 5 days. : Exposure to MFs induced significant decreases in total GSH levels and SOD activity but a significant increase in MDA levels in the liver. By contrast, SMF exposure significantly increased total LDH and total CPK activities in the muscle. The results revealed a significant increase in GABA levels in the brain, as well as decreases in haemoglobin, haematocrit, and red blood cell counts, in addition to platelet counts, after exposure to 20, 40, 60 and 80 Gauss MFs. After exposure to a 40 Gauss MF, the mice showed pathological changes in red blood cells, including changes to the outer membrane of the red blood cells (micronucleus and a serrated edge, with a mild incidence of echinocytes). In the group exposed to a 60 Gauss MF, examination of blood smears clearly showed changes in cell size, with the emergence of abnormal forms, including many areas with no red blood cells (rouleaux formation). With increasing intensity of exposure (80 Gauss), the red blood cells appeared completely different from their natural form and took the form of ovalocytes and bi-micronucleated erythrocytes, which appear in patients with anaemia. MF exposure caused different metabolic and haematological effects, which appeared to be related to the intensity of SMF exposure. The changes in the biochemical parameters of SMF-exposed mice probably reflect hepatic damage and anaemia caused by kidney failure. Further studies are needed to obtain a better understanding of the effects of MF on biological systems.
Nitrogen transformation stages into ammonia in broiler production: sources, deposition, transformation and emission to environment

Air quality is a major factor in intensive livestock management because air is the main vehicle for the dissemination of physical, chemical, and biological agents that affect the health and welfare of animals and humans. Ammonia is the main gaseous pollutant generated in poultry production. In this study, a literature review was conducted to highlight each nitrogen transformation stage during poultry production, while explaining the conversion mechanisms from the ingestion of crude protein to nitrogen volatilization into the atmosphere as ammonia gas. In summary, the steps for the synthesis of uric acid and the excretion of poultry, mineralization of nitrogen present in excreta, and volatilization of ammonia from litter are presented. Based on this review, the importance of understanding the sources and processes involved in ammonia generation and emission in poultry production is clear, thereby allowing the adoption of assertive measures that could minimize negative effects caused by ammonia emission.
Investigation on Tunneling-based Ternary CMOS with Ferroelectric-Gate Field Effect Transistor Using TCAD Simulation

Ternary complementary metal-oxide-semiconductor technology has been spotlighted as a promising system to replace conventional binary complementary metal-oxide-semiconductor (CMOS) with supply voltage (VDD) and power scaling limitations. Recently, wafer-level integrated tunneling-based ternary CMOS (TCMOS) has been successfully reported. However, the TCMOS requires large VDD (> 1 V), because a wide leakage region before on-current should be necessary to make the stable third voltage state. In this study, TCMOS consisting of ferroelectric-gate field effect transistors (FE-TCMOS) is proposed and its performance evaluated through 2-D technology computer-aided design (TCAD) simulations. As a result, it is revealed that the larger subthreshold swing and the steeper subthreshold swing are achievable by polarization switching in the ferroelectric layer, compared to conventional MOSFETs with high-k gate oxide, and thus the FE-TCMOS can have the more stable (larger static noise margin) ternary inverter operations at the lower VDD.
Shaping the Surface Deformation of Central and South Tibetan Plateau: Insights From Magnetotelluric Array Data

The ongoing India‐Asia collision since the Paleogene created the Tibetan Plateau, the most prominent elevated plateau on our planet. This convergence also contributed to the formation of two distinct types of active surface deformation of the plateau, namely, north–south trending normal fault systems and “conjugate” strike‐slip fault systems. The tectonics and geodynamic mechanism(s) behind this curious combination are still unclear, despite numerous theories proposed over past decades. Here we present a new three‐dimensional, lithospheric‐scale, electrical conductivity model with unprecedented resolution of the central part of Tibetan Plateau derived from the SINOPROBE magnetotelluric array data set and discuss its inferences related to this question. Our model reveals contrasting conductivity structures corresponding to the surface deformation patterns, namely, highly conductive lower crustal anomalies beneath the graben systems in the Lhasa and Qiangtang terranes and moderately resistive crustal features in the strike‐slip region near Bangong‐Nujiang Suture Zone. With the help of experimentally calibrated constraints between conductivity and melt fraction, the conductivity model and the inferred lateral viscosity distribution together suggest a weak lower crust beneath the graben regions, compared to a stronger crustal rheology associated with the strike‐slip zone. Here we expand the previously proposed “extensional extrusion” tectonic model in central Tibet to interpret our conductivity model and other geophysical/geodesic observations. The weak rheology under a N‐S directed primary stress may have caused the east–west extension of the graben regions, which further aides the eastward extrusion of the conjugate strike‐slip zone and eventually shapes the surface deformation of central Tibetan Plateau into its current, complex pattern.
Ongoing emergence: borderland high school DLBE students’ self-identifications as lingual people

ABSTRACT Conceptualizations of language as translanguaging (Otheguy, García, and Reid 2015) help us to render wholeness out of languages and groups of speakers socially constructed as distinct. Yet in practice teachers are still compelled to identify students by dichotomous institutional labels for discrete proficiencies in named languages: identity labels that are inevitably hierarchical and connected to inequity. This paper examines how youth in a two-way DLBE program on the US-Mexico border conceptualized themselves and their peers quite differently – as non-dichotomous – and their bilingualism as more continuously emergent. Based on interviews in a multiyear ethnography, we argue that youths’ conceptualizations of themselves as lingual (Flores 2013) people, rather than bilingual or monolingual, English learner or English proficient, are particularly important for serving our goals of equity in DLBE at the high school level.
A New Method to Lightweight Magnesium Using Syntactic Composite Core

Light weighting of magnesium-based materials is crucial for its extensive use in transportation applications. Hybrid processing of these materials in a shell-core pattern can substantially improve the specific properties of magnesium. In the present study, the Mg/Mg-20GMB (glass microballoon) hybrid composite was prepared using a disintegrated melt deposition technique. Microstructural characterization and mechanical properties of the developed as-cast Mg/Mg-20GMB hybrid composite were investigated. Results revealed that a unified metallurgical interface was formed between the Mg-20GMB core material and the pure Mg shell. Energy dispersive X-ray spectroscopy (EDX) results confirmed the existence of Mg2Si as the secondary phase in the Mg-20GMB core material. The hybrid Mg/Mg-20GMB composite exhibited much superior compressive yield strength (↑71.6%), lower ultimate compressive strength (↓23.25%), and enhanced ductility (↑186.48%) when compared to as-cast pure magnesium.
Calcium and phosphorus and their nanoparticle forms in poultry nutrition

SUMMARY The modern broiler chicken industry is connected with various disorders of the skeletal system. The fast-growing birds by increased weight gain often have leg problem which leads to economic losses. The correct bone development of broilers is highly correlated with calcium and phosphorus ratio (about 2:1) so providing these macroelements with diet seemed to be fundamental. The most common inorganic sources such as limestone, mono- and di-calcium phosphates are commonly used nowadays. The doses in feed generally are in the range of 6–6.5 g/kg for Ca and 2–3.5 g/kg for P, depending on the supplementation of phytase. However, the bioavailability of inorganic sources is poorer than organic sources. This fact is important in reference to their impact on the environment. Because of the continuous search for alternative sources of calcium or phosphorus, with better bioavailability due to, for example, their size, the scientific area of nanotechnology arouses increasing interest. It is well-known nanoparticles have a great potential even at very low doses. Some research focused on calcium-phosphorus compounds already demonstrated no negative effect on birds’ health, improvement in production results and bone quality, opportunity to use lower dosages of nano sources and decreasing content of Ca and P in excreta (by ca. 50%). Thus, this aspect may be the new trend during the next years. However, the further studies should be performed.
