Opportunistic Use of Successive Interference Cancellation in Reverse TDD HetNets

Cross-tier interference management is one of the major challenges in heterogeneous cellular networks (HetNets). Though the network throughput increases due to a better area spectral efficiency of a HetNet, there is possibility that high interference will make few link capacities close to zero when users regard interference as noise (IAN). In this letter, successive interference cancellation (SIC) is used to cancel the cross-tier interference in a reverse time division duplexing (RTDD) scheme. We demonstrate that by opportunistic use of SIC, a minimum guarantee on the sum link capacity can be ensured for an RTDD HetNet. This minimum sum link capacity is later on proved to be the maximum that can be achieved by orthogonal resource allocation schemes. Through system-level simulations for random allocation, it is shown that the proposed scheme is better than using SIC and IAN alone. To further improve the overall system capacity, an optimization problem for selecting co-channel users is formulated, and the Hungarian algorithm is employed to solve it.
Revisiting the Role of Intellectual Capital on Firms’ Performance: Indonesian Evidence

we believe those items can boost the firms’ performance. Intellectual capital is a group of knowledge assets that have a contribution to add value to stakeholders ABSTRACT: The purpose of this study is to revisit the effect of intellectual capital on firms’ performance. This study develops previous researches by measuring firm performance from various dimensions. Further analysis is performed by dividing the sample based on firm size. Using Indonesian data, the results provide evidence that intellectual capital has a positive effect on firm performance. Human capital efficiencies as an element of intellectual capital, also positively affect current and future performance. The authors also find that smaller firms receive more benefits than bigger ones in improving performance by investing more in intellectual capital. Our study contributes to the study of intellectual capital, especially in emerging markets.
Measurement Method for Monostatic Radar Cross Section of a Scaled
 Aircraft Model in Non-Anechoic Environment

Abstract This paper presents a method for measuring the radar cross section(RCS) of a scaled aircraft model with a low RCS value in environments other than electromagnetic anechoic chambers. We improve measurement accuracy by introducing coherent integration, coherent subtraction, and time-gating techniques to both eliminate the echoes of non-target objects and improve the signal-to-noise ratio. In this manner, we obtain measurement results that are consistent with the simulation results for complex structures even in environments where many error factors
Standardized ileal digestibility of amino acids and apparent metabolizable energy in corn and soybean meal for organic broiler chicken production in Ontario1

Abstract: Standardized ileal digestibility (SID) of amino acids (AA) and apparent metabolizable energy corrected for nitrogen (AMEn) in samples of organic corn and soybean meal (SBM) were determined. Conventional corn (CC) and SBM (CSBM) samples were tested for comparison. A total of 560, fourteen-day-old male broiler chickens (Cobb 500) were weighed, placed in cages (10 birds per cage), and allocated to seven (n = 8) semi-purified wheat-starch-based diets. Diets were (1) CC, (2) imported organic corn, (3) local organic corn, (4) CSBM, (5) imported organic SBM (OSBMI), (6) local organic SBM (OSBML), and (7) nitrogen-free wheat starch. Only few differences were observed on SID of AA; SID of lysine was lower (P = 0.002) in organic corn samples relative to CC, and SID of methionine was lower (P = 0.002) in OSBML sample relative to CSBM and OSBMI samples. The AMEn of CC was higher (P < 0.01) than that of organic corn samples. The AMEn of OSBML was higher (P < 0.001) than for CSBM and OSBMI; however, the value for OSBMI was higher (P < 0.001) than for CSBM. In conclusion, utilization of AA in conventional and organic feedstuffs was comparable; however, differences in energy utilization warrant considerations in organic broiler feed formulation.
Mobility, Balance, and Muscle Strength Adaptations to Short-Term Whole Body Vibration Training Plus Oral Creatine Supplementation in Elderly Women

Background: A decline in neuromuscular function can cause a decrease in physical fitness in elderly women. Objective: The present study aimed at investigating whether whole body vibration (WBV) training and creatine supplementation could affect muscle strength, mobility, and balance in elderly women in short- term. Methods: The participants were 22 healthy elderly women aged 60 to 80 years, who were randomly divided into the whole-body vibration and creatine (WBV + Cr) group, whole-body vibration and placebo (WBV + P) group, and control group. The whole-body vibration group performed exercises for 10 days. The participants in WBV + Cr group consumed 20 g oral creatine supplement per day from the first to the fifth day, which was followed by consuming 5 g of creatine per day for the next 5 days. To assess mobility performance, a 30-meter walking and tandem gait tests were applied. Static and dynamic balance were measured by Flamingo and Timed-Up and Go (TUG) tests. Muscle isometric and isotonic strength were assessed by dynamometer and leg extension tests. Results: No significant difference was found in static balance (P = 0.11), but WBV + Cr and WBV + P groups showed better results in dynamic balance (P = 0.001 and P = 0.009, respectively). Moreover, leg isotonic strength improved significantly in WBV + Cr and WBV + P groups (P = 0.001 and P = 0.001, respectively). However, leg isometric strength and 30-meter walking performance significantly improved only in WBV + Cr group compared to the control group. Moreover, no significant differences were observed in isometric strength of the hand (P = 0.89) and tandem gait test results among the groups (P = 0.25). Conclusions: A short-term WBV exercise improves isotonic strength of the leg muscle and dynamic balance, while creatine supplementation with and without WBV training increases isometric strength of the leg muscle and mobility in elderly women.
Biogeography and morphology of a poorly known diatom Dorofeyukea rostellata (Hustedt) Kulikovskiy & Kociolek

espanolDorofeyukea rostellata es un representante raro y poco conocido del genero Dorofeyukea. Hasta la fecha, esta especie solo ha sido registrada fuera de Europa. En dos lagos croatas, encontramos una diatomea en apariencia similar a Dorofeyukea rostellata y en las condiciones fisicas y quimicas correspondientes. Debido a la incierta posicion taxonomica de este taxon, el material tipo de Dorofeyukea rostellata y una especie estrechamente relacionada, Navicula grimmeioides, se analizaron mediante microscopia de luz y electronica de barrido. Tras una investigacion detallada, pudimos distinguir claramente la poblacion croata de N. grimmeioides. Sin embargo, la poblacion croata y el tipo de material de D. rostellata diferian solo en caracteristicas menores. La diferencia mas obvia es la forma de las areolas. Sin embargo, las diferencias pueden deberse al grado de silicificacion, que a menudo depende de las condiciones ambientales. Como casi todas las demas caracteristicas de la poblacion croata se superponian con del material tipo de D. rostellata, lo identificamos como D. rostellata. Ademas, los analisis de microscopia electronica de barrido tambien revelaron que N. grimmeioides tambien pertenece al genero Dorofeyukea, por lo que se propuso una nueva combinacion. EnglishDorofeyukea rostellata is a rare and poorly known representative of Dorofeyukea genus. To date, this taxon has only been recorded only outside of Europe. In two Croatian lakes, we found a diatom in appearance similar to Dorofeyukea rostellata and within corresponding physical and chemical conditions. Due to the uncertain taxonomical position of this taxon, type material of Dorofeyukea rostellata and a closely related species, Navicula grimmeioides, were analysed by means of light and scanning electron microscopy. Upon a detailed investigation, we could clearly distinguish the Croatian population from N. grimmeioides. However, the Croatian population and the type material of D. rostellata differed only in minor characteristics. The most obvious difference is the shape of areolae. Nevertheless, differences between the shapes of the areolae can be caused by the degree of silicification, which often depends on the environmental conditions. Since almost every other characteristic of the Croatian population overlapped with that of the type material of D. rostellata we identified it as D. rostellata. Additionally, scanning electron microscopy analyses also revealed that N. grimmeioides belongs to the genus Dorofeyukea, so its new combi-nation was proposed.
Towards Detecting Building Facades with Graffiti Artwork Based on Street View Images

As a recognized type of art, graffiti is a cultural asset and an important aspect of a city’s aesthetics. As such, graffiti is associated with social and commercial vibrancy and is known to attract tourists. However, positional uncertainty and incompleteness are current issues of open geo-datasets containing graffiti data. In this paper, we present an approach towards detecting building facades with graffiti artwork based on the automatic interpretation of images from Google Street View (GSV). It starts with the identification of geo-tagged photos of graffiti artwork posted on the photo sharing media Flickr. GSV images are then extracted from the surroundings of these photos and interpreted by a customized, i.e., transfer learned, convolutional neural network. The compass heading of the GSV images classified as containing graffiti artwork and the possible positions of their acquisition are considered for scoring building facades according to their potential of containing the artwork observable in the GSV images. More than 36,000 GSV images and 5000 facades from buildings represented in OpenStreetMap were processed and evaluated. Precision and recall rates were computed for different facade score thresholds. False-positive errors are caused mostly by advertisements and scribblings on the building facades as well as by movable objects containing graffiti artwork and obstructing the facades. However, considering higher scores as threshold for detecting facades containing graffiti leads to the perfect precision rate. Our approach can be applied for identifying previously unmapped graffiti artwork and for assisting map contributors interested in the topic. Furthermore, researchers interested on the spatial correlations between graffiti artwork and socio-economic factors can profit from our open-access code and results.
Long-term single-cell imaging and simulations of microtubules reveal driving forces for wall pattering during proto-xylem development

Plants are the tallest organisms on Earth; a feature sustained by solute-transporting xylem vessels in the plant vasculature. The xylem vessels are supported by strong cell walls that are assembled in intricate patterns. Cortical microtubules direct wall deposition and need to rapidly re-organize during xylem cell development. We established long-term live-cell imaging of single Arabidopsis cells undergoing proto-xylem trans-differentiation, resulting in spiral wall patterns, to investigate the microtubule re-organization. The initial disperse microtubule array rapidly readjusted into well-defined microtubule bands, which required local de-stabilization of individual microtubules in band-interspersing gap regions. Using extensive microtubule simulations, we could recapitulate the process in silico and found that local recruitment of microtubule-bound nucleation is critical for pattern formation, which we confirmed in vivo. Our simulations further indicated that the initial microtubule alignment impact microtubule band patterning. We confirmed this prediction using katanin mutants, which have microtubule organization defects, and uncovered active KATANIN recruitment to the forming microtubule bands. Our combination of quantitative microscopy and modelling outlines a framework towards a comprehensive understanding of microtubule re-organization during wall pattern formation.
A Review of Orbital Angular Momentum Vortex Beams Generation: From Traditional Methods to Metasurfaces

In this paper, we review the generation of vortex beams carrying orbital angular momentum in the microwave domain. We firstly present the theory of Laguerre–Gaussian beams where it is demonstrated that they carry such type of momentum. We further provide an overview of the classical methods used to generate orbital angular momentum vortex beams, which rely on two main methods; plane wave to vortex wave conversion and direct generation using radiating antennas. Then, we present recent progress in the physics of metasurfaces devoted to the generation of vortex beams with a discussion about reflective and transmissive metasurfaces for plane wave to vortex wave conversion as well as methods to reduce the intrinsic divergence characteristics of vortex beams. Finally, we conclude on this rapidly developing research field.
Rad51 stabilizes the ends of two adjacent DSBs in yeast

DNA double-strand breaks (DSBs) are a major form of DNA damage, and its accurate repair is critical for maintaining genomic stability and preventing cancer. Repair of DSBs is mainly through two pathways, homology-directed DNA repair (HDR) and non-homologous end joining (NHEJ). Compared with NHEJ, HDR has higher fidelity, so the study of interrelated factors in homologous recombination pathway is of particularly important. In this paper, we constructed an I-SceI model controlled by a galactose promoter that produces a DSB or two adjacent DSBs on a single chromosome. Rad50 and Rad51 genes are further deleted in these models. Sensitivity experiments show that Rad51 stabilizes the ends of two adjacent DSBs in yeast. Deletion of Rad51 gene causes the sequence between two adjacent DSBs to drop out directly to form a large gap. If this gap is larger, the efficiency of NHEJ will be greatly reduced, resulting in the deaths of the strain. Our research shows that Rad51 stabilizes the ends of two adjacent DSBs in yeast.
Causal-comparative Study: Differences in Academic Achievement by Levels of Social-emotional Skills in Grade Five Students

Students’ social-emotional skills contribute to academic achievement and life success. This causal-comparative study examined differences in mathematics and English Language Arts (ELA) achievement test scores among grade five students by their levels of proficiency (low, moderate, or high) in particular social and emotional skills, namely, academic self-efficacy, persistence, self-control, mastery orientation, and social competence. Participants were 115 grade five students from Title I schools in a metropolitan school district in south Florida. Each social and emotional skill was assessed using the Child Trends Social and Emotional Skills Survey battery. Multivariate Analysis of Variance, Analysis of Variance, and post hoc tests were used to test null hypotheses that there were no statistically significant differences in Florida Standards Assessment mathematics and ELA achievement test scores among participants by their levels of proficiency in the social-emotional skills examined in the study. Statistically significant differences in math scores were found among participants from moderate to high levels of persistence, from moderate to high levels of academic self-efficacy, and from moderate to high levels of self-control. Statistically significant differences in ELA scores were found among participants from moderate to high levels of persistence, from moderate to high levels of social competence, from moderate to high levels of self-control, from moderate to high levels of academic self-efficacy, and from moderate to high levels of persistence combined with moderate to high levels of self-control. Recommendations for future research are presented.
Facilitators of Students’ Moderate Drinking in a Wet versus Dry Drinking Culture

ABSTRACT Compared to drinking abstinence, the encouragement of moderating drinking is a pragmatic and sensible approach to addressing excessive alcohol consumption. This study explores how students’ perceptions of facilitators of moderate drinking vary between a wet (New Zealand) and dry drinking country (Vietnam). A qualitative survey was conducted with 227 and 278 respondents from New Zealand and Vietnam, respectively. Aligning with the behavioral ecological framework, the content analysis reveals that students perceive several factors to encourage moderate drinking at the individual (e.g., controllability and coping skills), social (e.g., peer influences), and environmental level (e.g., alternatives to drinking). The response variations between the two countries provided novel insights into cultural differences in students’ perceptions, with internal factors exerting stronger influence in the dry culture and external influences being more prominent in the wet culture. The findings offer recommendations to inform nonprofit and social marketing in the areas of alcohol control.
Using Bioprinting to Tissue Engineer Microvascularized Constructs for Skeletal Muscle Repair

One challenge in tissue engineering (TE) is designing a construct which ensures adequate oxygen diffusion and removal of waste throughout the implanted tissue. In native tissue, the maximum distance between any cell and capillary is limited to the diffusion distance of oxygen, or 100–200 μm1. Mimicking this dense microvasculature in TE constructs is critical to cell viability and function, particularly in thick implants, such as those for skeletal muscle repair2. There have been many recent advancements in using TE to develop skeletal muscle constructs for the treatment of volumetric muscle loss (VML) in injuries incurred by soldiers and civilians. We have developed a tissue engineered muscle repair (TEMR) technology which consists of myoblasts seeded onto a porcine bladder acellular matrix (BAM). While TEMR has previously been reported to result in 60–70% functional recovery in rodent models within 2 months after implantation3,4, we hypothesize that incorporating endothelial cells (ECs) and pericytes in the TEMR will accelerate the rate and magnitude of functional recovery by facilitating anastomosis with the recipient microcirculation and increasing perfusion into the construct.
Cause Lawyering and Movement Tactics: Disability Rights Movements in South Korea and Japan

We investigate cause lawyers&#8217; roles in movements for the domestic adoption of international human rights norms. Social movements scholarship often assumes that lawyers will divert activism toward institutional tactics, while the sociolegal studies literature emphasizes that lawyers are active in diverse ways across venues. A paired comparison of antidiscrimination movements in South Korea and Japan reveals how critical junctures in regime history shape the tactical repertoires that cause lawyers bring to their interactions with movement actors, and thus also movement tactics. This research advances scholarship on professionals in social movements, cause lawyers as norm entrepreneurs, and legal mobilization in East Asia.
Re‐Engineering Poly(Acrylic Acid) Binder toward Optimized Electrochemical Performance for Silicon Lithium‐Ion Batteries: Branching Architecture Leads to Balanced Properties of Polymeric Binders

Silicon is a promising anode material for lithium‐ion batteries with its superior capacity. However, the drastic volume changes during lithiation/delithiation cycles hinder the cycling performance, resulting in particle pulverization, conductivity loss, and an unstable electrode–electrolyte interface. Herein, a series of synthetic polymeric binders, poly(acrylic acid‐co‐tetra(ethylene glycol) diacrylate)—featuring a poly(acrylic acid) (PAA) backbone branched via tetra(ethylene glycol) diacrylate (TEGDA)—are developed that edge toward evidencing well‐balanced properties to confront capacity fading in Si‐based electrodes. The incorporation of ether chain not only leads to the branching architecture of the PAA backbone, thus affecting its mechanical properties, but also promotes the conductivity of Li ions. As a result, a synergistic performance improvement is observed in both half and full cells. The best‐performing cell using a branched PAA binder (bPAA) with a feeding molar ratio ([TEGDA]:[acrylic acid(AA)]) of 0.2 results in a 10% increase in initial capacity and a 31% increase in capacity retention over 100 cycles compared to the linear PAA cell. The cross‐sectional microscopic images of the cycled electrodes reveal that bPAA binders can drastically reduce the electrode expansion. This improvement results from the well‐balanced properties of the polymer design, which could guide further development for more advanced binder materials.
Low-Power Reconfigurable Sensing Circuitry for the Internet-of-Things Paradigm

Low-Power Reconfigurable Sensing Circuitry for the Internet-of-Things Paradigm Alexander Todd DiLello With ubiquitous wireless communication via Wi-Fi and nascent 5th Generation mobile communications, more devices – both smart and traditionally “dumb” – will be interconnected than ever before. This burgeoning trend is referred to as the Internet-of-Things. These new sensing opportunities place a larger burden on the underlying circuitry that must operate on finite battery power and/or within energy-constrained environments. New developments of low-power reconfigurable analog sensing platforms like field-programmable analog arrays (FPAAs) present an attractive sensing solution by processing data in the analog domain while staying flexible in design. This work addresses some of the contemporary challenges of lowpower wireless sensing via traditional application-specific sensing and with FPAAs. A large emphasis is placed on furthering the development of FPAAs by making them more accessible to designers without a strong integrated-circuit background – much like FPGAs have done for digital designers.
Unpredictable times: the extent, characteristics and correlates of insecure hours of work in Britain

This article presents new British evidence that suggests that cutting working hours at short notice is twice as prevalent as zero‐hours contracts and triple the number of employees are very anxious about unexpected changes to their hours of work. The pay of these employees tends to be lower, work intensity higher, line management support weaker and the threat of dismissal and job loss greater. In addition, the well‐being of these employees is lower and they are less committed to the organisations that employ them. However, the prevalence of insecure working hours is reduced by workplace level employee involvement exercised individually or through collective representation.
