First Principles Calculations on Elastic, Thermodynamic and Electronic Properties of Co2Zr and Co2Ti at High Temperature and Pressure

Co2Zr and Co2Ti are both cubic crystals with a Cu2Mg-type structure. The elastic, thermodynamic and electronic properties of the intermetallic compounds Co2Zr and Co2Ti are investigated by using ab initio plane-wave pseudopotential density functional theory (PWPDFT) and generalized gradient approximation (GGA) under high temperature and pressure. The partially calculated results are consistent with the available experimental data. The elastic properties of Co2Zr and Co2Ti under high pressure were first studied by first principles calculations. The results indicate that the elastic constants, elastic modulus and Poisson’s ratio are functions of pressure, indicating that the effect of pressure on the ductility and anisotropy is significant. The thermodynamic properties are also calculated by the quasi-harmonic Debye model. In the range of 0~100 GPa pressure and 0~1500 K temperature, the Debye temperature Θ, the heat capacity CV and the thermal expansion α vary with pressure and temperature. Co2Ti has a higher Debye temperature than Co2Zr under the same pressure. Decreasing temperature and increasing pressure have the same effects on CV and α. The electron density difference and density of states of Co2Zr and Co2Ti are finally investigated. The results show that both Co2Zr and Co2Ti are typically metal crystals but Co2Zr has greater covalence than Co2Ti.
Terbium-Tetracarboxylate Framework as a Luminescent Probe for the Selective Detection of Nitrofurazone

A novel terbium-tetracarboxylate framework with the 5,5’-(diazene-1,2-iyl)diisophthalic acid (H4abtc) ligand, formulated as [Tb(Habtc)(DMSO)(H2O)2]n (ZTU-5), has been synthesized and structurally characterized. ZTU-5 features a 2D-layered structure constructed by the binuclear terbium secondary building units (SBUs) and abtc4– ligand, which can be further expanded into a 3D-supramolecular framework by the hydrogen bond interactions. In addition, the magnetic and fluorescence properties of ZTU-5 are investigated and ZTU-5 exhibits highly selective and sensitive detection of nitrofurazone (NZF).
The impact of grocery retail superstores location on the customer’s perceived quality of servicescape in Jordan

Abstract The aim of this study was to examine the impact of customers’ perceived location quality of retail stores on the perceived quality of the servicescape. Therefore, this study examined to what extent the customers shopping at more convenient, accessible, visible and attractive location; are shopping also at more convenient store environment in term of visual, olfactory, and auditory cues. Three retail superstores were surveyed in Amman the capital of Jordan. These retail superstores were: Carrefour, Safeway, and C-Town. A questionnaire was designed to collect the data from customers of these retail stores. A sample of 1055 customers was surveyed. Multiple linear regression analysis was used to analyze the relationship between the location factors and the servicescape factors. This study revealed that the impact of retail stores location dimensions on perceived servicescape quality was moderate to low in two cases, and low in one case. This indicates that locating store’s branches in high access, visible, and attractive location have low to moderate servicescape quality. In addition, retail stores that exist in good locations have better visual cues than auditory and olfactory cues. This result was the same for the three retail stores. The theoretical stance of retail stores location and servicescape quality is too fragmented. The majority of previous studies have focused on reporting the location or servicescape as a separated construct. Very limited studies have investigated this issue in service sector in general and retailing in particular.
Long-term activity-induced changes in the brain : a study of translational regulation and structural plasticity

Long-term memory can be distinguished from short-term memory by its requirement for protein synthesis. Converging evidence implicates a short period around the time of training during which new proteins are produced that are important for the consolidation of short-term memory into long-term memory. These processes have cellular correlates L-LTP is dependent on translation whereas E-LTP is not. Though traditional studies of LTP have pointed to transcription as a primary control point in these phenomena, increasing evidence suggests translation as a key regulatory step during the induction of these processes. Changes in the morphology of neurons may be the consequence of the protein synthesis required for long-term memory. These changes in morphology may also underlie the behavioral changes seen after chronic stress and in stress-related disorders like major depression, PTSD, anxiety disorders and Cushing's syndrome.
Diagnostic Value of miR-1260b in Cervical Cancer: A Pilot Study

Cervical cancer is the fourth most common cancer in women, with approximately 528,000 new cases and 266,000 women dying of it per year in the world. MicroRNAs have recently been in the spotlight as potential biomarkers that regulate gene expression and are involved in tumorigenesis. In the present study, we evaluated miR-1260b as a potential biomarker for screening of cervical cancer by quantitative reverse transcription PCR. We profiled the TCGA data of miR-1260b in 307 cervical cancer tissues. Then, miR-1260b expression levels in 10 cervical cancer tissues and 10 non-cancerous tissues were investigated in a pilot study. miR-1260b was found to be significantly up-regulated in cervical cancer FFPE tissues as compared to those in cervical normal FFPE tissues ( P = 0.006). The mean expression level of miR-1260b in late-stage (IIB-IVB) was higher than in those with early-stage (IA-IIA). Furthermore, high miR-1260b was found to be associated with high hTERT and Ki-67 mRNA expression, which are representative of tumor prognosis. The results of the pilot study suggest that miR-1260b may be used as a novel biomarker for improving the diagnosis of cervical cancer.
Novel water-based nanolubricant with superior tribological performance in hot steel rolling

Novel water-based nanolubricants using TiO2 nanoparticles (NPs) were synthesised by adding sodium dodecyl benzene sulfonate (SDBS) and glycerol, which exhibited excellent dispersion stability and wettability. The tribological performance of the synthesised nanolubricants was investigated using an Rtec ball-on-disk tribometer, and their application in hot steel rolling was evaluated on a 2-high Hille 100 experimental rolling mill, in comparison to those without SDBS. The water-based nanolubricant containing 4 wt% TiO2 and 0.4 wt% SDBS demonstrated superior tribological performance by decreasing coefficient of friction and ball wear up to 70.5% and 84.3%, respectively, compared to those of pure water. In addition to the lubrication effect, the suspensions also had significant effect on polishing of the work roll surface. The resultant surface improvement thus enabled the decrease in rolling force up to 8.3% under a workpiece reduction of 30% at a rolling temperature of 850 °C. The lubrication mechanisms were primarily ascribed to the formation of lubricating film and ball-bearing effect of the TiO2 NPs.

Optimal Transmission Power Scheduling of Networked Control Systems Via Fuzzy Adaptive Dynamic Programming

This article considers the transmission power scheduling in the control of a linear plant when the plant state is transmitted from a sensor to the controller over a wireless fading channel. The power allocated to these transmissions determines the probability of successful packet reception. This article focuses on investigating how much power should be assigned to transmit the data packet at each time. A new framework of optimal power allocation is established by introducing a cost function, which weighs the control performance and energy cost. First, a necessary and sufficient condition for the existence of the solution to finding an admissible schedule is given. Then, by combining an adaptive dynamic programming technique with fuzzy approximation theory, a new state-dependent scheduling algorithm is proposed to find the optimal power allocation policy. The convergence analysis shows that the proposed power scheduling algorithm can approximate the optimal solution on a compact set with a desired precision. Simulation results are presented to illustrate the effectiveness of the proposed algorithm.
Identification of Aedes aegypti and its Respective Life Stages by Real-Time PCR

Abstract : An Aedes aegypti specific fluorogenic probe hydrolysis (TaqMan) PCR assay was developed for real-time screening using a field-deployable thermocycler. Laboratory-based testing of Ae. aegypti, Ae. aegypti (Trinidad strain); Culex pipiens; Culex pipiens quinquefasciatus; Anopheles stephensi; Ochlerotatus taeniorhynchus individual adult mosquitoes and mixed pools (n=10) demonstrated 100% concordance in both in vitro sensitivity (6/6) and specificity (10/10). A single adult Aedes aegypti was identified in a pool of 100 non-Aedes aegypti mosquitoes. The limit of detection of Aedes aegypti egg pools was 5 individual eggs. Field-testing was conducted in central Honduras. An Aedes aegypti and Culex spp. panel of individual and mixed pools (n = 30) of adult mosquitoes, pupae, and larvae demonstrated 100% concordance in sensitivity (22/22) and 97% concordance in specificity (29/30) with one false positive. Field-testing of an Aedes aegypti and Culex spp. blind panel (n = 16) consisting of individual and mixed pools of adult mosquitoes, pupae, and larvae demonstrated 90% concordance in sensitivity (9/10) and 88% concordance in specificity (14/16).

The results of the study showed that all the observed variables improved significantly except for job performance.
Model systems for understanding charge transfer at semiconductor/catalyst interfaces

The International Energy Agency (IEA) estimated the world energy use to be about 18 TW per year [1]. Currently, this amount of energy is mostly provided by combusting fossil fuels. However, the world’s reserve of fossil fuels is finite, and the combustion of fossil fuels releases pollution and greenhouse gasses causing severe environmental problems. One of the most significant environmental side effects of burning fossil fuels is global warming. To avoid these detrimental effects, the use of sustainable energies is imperative. Among the different sustainable energy sources, the sun is by far the one with the largest potential. However, due to diurnal, regional, and seasonal variations of sunlight, the energy needs to be stored and utilized efficiently. Direct photoelectrochemical (PEC) water splitting is an elegant way to store sunlight by means of chemical bonds. In the process, water is reduced and oxidized to hydrogen and oxygen, respectively. The oxidation of water is generally the limiting factor in a PEC cell and is, therefore, the main focus of this dissertation. We combine an n-type semiconductor with a co-catalyst: the semiconductor is the light absorber and provides the photovoltage, while the co-catalyst aids the oxidation reaction. We investigate the energetics at the semiconductor/co-catalyst interface, which are crucial for the charge transfer processes. In order to study the energetics, we tune the valence band position of the semiconductor and the co-catalyst and investigate the charge transfer processes in a combined semiconductor/co-catalyst system. In the first part, we investigated the role of an atomic layer deposited (ALD) MnOx co-catalyst and its thickness on the photoelectrochemical performance of BiVO4 photoanodes. The modified MnOx/BiVO4 sample with a thickness of ~4 nm shows the highest photocurrent. X-ray photoelectron spectroscopy (XPS) studies reveal that addition of MnOx results in a modification of the surface band bending of BiVO4, therefore, reducing surface recombination. At the same time, increasing the thickness of MnOx beyond the optimal 4 nm introduces shunting pathways, as shown by energy dispersive x-ray scanning transmission electron microscopy (EDX-STEM) and redox electrochemistry. This cancels out the band bending effect, which explains the observed
Home care workers caring for adults with heart failure need better access to training and technology: A role for implementation science

Abstract Although highly involved in heart failure (HF) patients’ care, home care workers (HCWs) lack HF training and are poorly integrated into the healthcare team. For its potential to address these challenges, we examined the role of technology among HCWs caring for HF patients. We conducted 38 interviews with key stakeholders. Overall, four themes emerged. Participants reported that technology is critical for HF care, but existing systems are outdated and ineffective. HCWs also have limited access to electronic resources. Technology, training, and principles of implementation science can be leveraged to improve HCWs’ experience in caring for HF patients and home healthcare delivery.
Broker Organizations to Facilitate Cross‐Sector Collaboration: At the Crossroad of Strengthening and Weakening Effects

Cross-sector collaboration has emerged as an important way for public management to address complex social issues. Given the manifold challenges of governing and implementing such collaborations, scholars emphasize the benefits of using broker organizations to facilitate and strengthen cross-sector collaboration. Nevertheless, our comparative longitudinal case study of broker organizations that support global health partnerships shows a less straightforward pattern: Despite their good intentions, two of the four broker organizations we analyzed subtly weakened their collaboration by gradually replacing the partners’ cross-sectoral tasks and decision making with unilateral, broker-based ones. By juxtaposing this pattern with the other two broker organizations’ trajectory, we reveal the processes underlying brokers’ role drift and unintended collaborative weakening and those allowing them to maintain their facilitation role. On this basis, our study exposes overlooked collaboration dynamics to reveal the boundaries of using broker organizations as a mechanism to facilitate cross-sector collaboration. Evidence for Practice • Partner-created broker organizations can help convene, coordinate, and mediate between diverse collaboration partners. However, filling implementation gaps may be beyond their capacity and their unilateral actions might undermine the collaborative advantage. • Instead of buffering systematic implementation challenges, broker organizations may need to escalate them to motivate the partners to adjust their collaboration.
Classification of Epileptic IEEG Signals by CNN and Data Augmentation

Epileptic focus localization in patients with epileptic seizures is essential when surgery is needed. Recent studies show that this can be done automatically using machine learning approaches. However, well-designed feature extraction methods are often computationally demanding, requiring a large amount of data labeled by physicians, which is time consuming and impractical. In this paper, we firstly introduce a one-dimensional convolutional neural network (1D-CNN) model for epileptic seizure focus detection which avoids the manual, time-consuming feature extraction Moreover, to reduce the necessary number of training samples, we introduce an approach for data augmentation. The experimental results demonstrate the efficiency of the proposed method, with a nearly 3% improvement in performance using the data enhancement method compared to the best result obtained using the traditional feature extraction method.
Effect of Food and Temperature on The Biology of Typhlodrompis swirskii (Athias-Henriot) (Acari: Phytoseiidae)

The biology of Typhlodrompis swirskii (Athias-Henriot) fed on different associated phytophagous mites, insects and pollens was studied at 25 C. These were Eutetranychus orientalis (Klien) (immatures and adults), Cenopalpus pulcher (C. & F.) females, Panonychus ulmi (Koch) (females), Tetranychus urticae Koch (immatures and eggs), Tydeus californicus (Banks) moving stages; whitefly Bemisia tabaci (Gennadius) (eggs and 1 & 2 instar nymphs), the scale insects Chrysomphalus ficus Rilly and Coccus hesperidium (Linnaeus) (eggs and nymphs), the aphid Aphis duranta Theo (adults), date palm pollens Phoenix dactylifera L. and castor bean pollens Ricinus communis L. Amount of consumption, as well as the predation capacity were estimated. Mites and date palm pollens were more suitable than insects and castor bean pollens; also immatures of E. orientalis gave the shortest female life cycle (10.8 days) and the highest female fecundity (38.0 eggs/♀). Feeding T. swirskii on E. orientalis immatures at 15, 20, 25, 28, 30, 32 and 35C, the developmental durations averaged 18.5, 14.3, 10.8, 9.0, 7.7, 6.8 and 6.1 days respectively. The intrinsic rate of natural increase (rm) and the net reproduction (Ro) represented the best values 0.269 and 26.48 respectively at 32C the mean generation time decreased with increasing temperature (10.971 days at 35 C).

Constant Envelope Massive MIMO-OFDM Precoding: an Improved Formulation and Solution

Constant Envelope (CE) precoding is an efficient technique for systems based on massive antenna arrays since the constant amplitude of the transmit signal facilitates the use of power efficient non-linear transmitter circuitry, such as power amplifiers (PAs). On the other hand, Orthogonal frequency-division multiplexing (OFDM) is a well-known multicarrier transmission scheme which is used to mitigate the effects of multipath propagation, but usually leads to high peak-to-average-power ratio (PAPR). Herein, the problem of CE MIMO-OFDM precoding for transmission over frequency selective channels is tackled. First, a novel efficient formulation is proposed, where the precoding problem is formulated as an unconstrained nonlinear least-squares problem. Next, using the new formulation the problem is solved using the Gauss-Newton algorithm. Numerical results show that the proposed solution is more efficient than the current state of the art techniques both from the aspect of computational complexity and the overall system performance.

Electrochemical Characterization of CVD-Grown Graphene for Designing Electrode/Biomolecule Interfaces

In research on enzyme-based biofuel cells, covalent or noncovalent molecular modifications of carbon-based electrode materials are generally used as a method for immobilizing enzymes and/or mediators. However, the influence of these molecular modifications on the electrochemical properties of electrode materials has not been clarified. In this study, we present the electrochemical properties of chemical vapor deposition (CVD)-grown monolayer graphene electrodes before and after molecular modification. The electrochemical properties of graphene electrodes were evaluated by cyclic voltammetry and electrochemical impedance measurements. A covalently modified graphene electrode showed an approximately 25-fold higher charge transfer resistance than before modification. In comparison, the electrochemical properties of a noncovalently modified graphene electrode were not degraded by the modification.
‘Sometimes fear gets in all your bones’: towards understanding the complexities of risk in development work

ABSTRACT In the context of increasing risk for aid workers, a growing body of scholarship is focused on risk management in contexts of humanitarian assistance and development work. Much less attention, however, has been given to how staff and volunteers experience such risks. This paper adopts a feminist geographical approach to explore how development workers make meaning of risk in specific contexts. Adopting a qualitative approach, it draws upon 14 semi-structured in-depth interviews with international (7) and local (7) staff of an international educational and sporting non-governmental organisation (NGO) in Afghanistan. After exploring differences between local and foreign staff perceptions of risk, it also offers a gendered analysis of risk for women development workers in Afghanistan. In so doing, this paper contributes to the growing body of literature in ‘Aidland’ studies by revealing the complex understandings of risk and fear by both foreign and local staff in the same geographical and organisational context. For NGOs seeking to make life-saving decisions based on the calculation of risk, this paper evidences the need to also create space for the voices of local and foreign staff whose experiences of risk will be highly relational, embodied, gendered and context specific.
