Domain wall pinning and dislocations: Investigating magnetite deformed under conditions analogous to nature using transmission electron microscopy

In this study, we deformed samples cut from a single magnetite octahedron and used transmission electron microscopy (TEM) and magnetic measurements to experimentally verify earlier computational models of magnetic domain wall pinning by dislocations and to better understand the nature of dislocations in magnetite. Dislocations in magnetite have been of interest for many decades because they are often cited as a likely source of stable thermoremanent magnetizations in larger multidomain (MD) magnetite grains, so a better understanding of dislocation effects on coercivity in MD magnetite is crucial. TEM imaging shows, for the first time, domain walls sweeping through the magnetite sample and being pinned at dislocations. In agreement with theory, these findings demonstrate that domain walls are more strongly pinned at networks of dislocations than at single dislocations and that domain walls pinned at longer dislocations have higher microcoercivities than those pinned at shorter dislocations. This experimentally illustrates the ability of dislocations to increase the coercivity of larger multidomain magnetite grains. The observed values for microcoercivity and bulk coercivity are in reasonable agreement with theoretical calculations. Burgers vectors were determined for some dislocations to verify that they were in keeping with expected dislocation orientations. The dislocations were found to be primarily located on close‐packed {111} planes within the magnetite. Deformation caused only a minor change in bulk coercivity, but first‐order reversal curve diagrams show populations with increased coercivity not visible in hysteresis loops.
A video-tracking based serious game for motor rehabilitation of post-stroke hand impairment

This work describes the development of a serious game focused on health treatment. The Handcopter Game was designed to support the recovery of motor function in patients who have suffered a stroke recently. We propose a non-conventional low cost input device to funtion as the game controller. It detects the patient's hand movements via computer vision algorithms and map that to movements on the game character in the virtual environment. The premise is that the game play makes patients execute hand movements typically found in a physiotherapy session. We also discuss how to use this game as part of the patient's treatment. Finally, we present the results collected when real patients played the game as part of their recovery treatment.
Energy-Efﬁcient Thread Migration via Dynamic Characterization of Resource Utilization

The affinity of threads with cores in current chipmultiprocessor systems has a substantial impact on the execution time, latency, and power consumption of multi-threaded workloads. Finding an optimal mapping configuration of threads is a significant challenge as it requires detailed knowledge of each thread’s demands for shared system resources. This paper describes a software-based strategy that makes judicious thread migration decisions founded on careful inspection of dynamic resource utilization. The main novelty of the system reported in this paper is the extensive utilization of hardware performance counters to develop a set of synthesized metrics that capture resource contention among co-running threads. Experimental results with a set of contemporary parallel workloads, show that the system can achieve significant improvements in power consumption and performance over the default scheduling heuristics implemented in the Linux kernel. Keywords–energy efficiency; thread scheduling; workload characterization.
Global monthly sea surface nitrate fields estimated from remotely sensed sea surface temperature, chlorophyll, and modeled mixed layer depth

Information about oceanic nitrate is crucial for making inferences about marine biological production and the efficiency of the biological carbon pump. While there are no optical properties that allow direct estimation of inorganic nitrogen, its correlation with other biogeochemical variables may permit its inference from satellite data. Here we report a new method for estimating monthly mean surface nitrate concentrations employing local multiple linear regressions on a global 1° by 1° resolution grid, using satellite‐derived sea surface temperature, chlorophyll, and modeled mixed layer depth. Our method is able to reproduce the interannual variability of independent in situ nitrate observations at the Bermuda Atlantic Time Series, the Hawaii Ocean Time series, the California coast, and the southern New Zealand region. Our new method is shown to be more accurate than previous algorithms and thus can provide improved information on temporal and spatial nutrient variations beyond the climatological mean at regional and global scales.
Will Low-Income Populations Love Spicy Foods More? Accounting for Tastes

Based on the Theory of Rational Addiction (TORA), this paper identifies the correlation between income and the preference for spicy foods by analysing the China Health and Nutrition Survey (CHNS) data. The results show that compare with high-income residents of same area, the low-income residents prefer to spicy foods in China. The regression results of IV and Lewbel IV all support it. According to the result, the channel of health behaviours and health awareness are possible causal channels for the negative correlation between income and the preference for spicy foods, rather than health capital stock and food selection.
Wage differentials in Mexico's urban labor market

We estimate wage differentials across different segments of the Mexican urban labor market. We use a panel sample of individuals which allows us to control for workers' observable and non-observable characteristics, by focusing on wage changes reported by individuals who move from one sector to another. The results suggest that the wage differential between the formal and informal sectors is positive and significant, and larger than the differential between industry and services. While we cannot distinguish formally between different hypotheses that could explain the existence of these differentials, our results seem to suggest that the main distortions in the Mexican labor market appear to be related more to labor regulations that affect the allocation of labor between the formal and informal sectors, than to differences in intrinsic characteristics of the production processes in industry and services.
Altruistic Utility Functions

Utility functions that embody nonpaternalistic altruism, to be called altruistic utility functions, can be regarded as being formed through social interactions among altruistic individuals. As such, they possess socially formed characteristics, on which the present paper focuses. Assuming linear altruism, the paper shows that, as the degrees of altruism increase, different individuals’ altruistic utility functions become more similar and converge to a single function in the limit if and only if everybody is altruistically connected to everybody else.
A Secure Framework for Detecting and Preventing Grayhole Attack (SFAODV)

— Mobile Ad-hoc Network (MANET) is a network where nodes cooperate each other to communicate data through multi-hop nodes. It has numerous applications in the current and future networking generations. Due to the popularity of Internet of Things (IOT), where everything can be connected, there is a vital role of MANET in communicating among the IOT devices to exchange information. However providing QOS in terms of security to this network is an important issue. In this paper we investigate grayhole attack in MANET and do analysis with ns2 experimental results and show how the performance degradation of the MANET occurs due to such attack. We then propose a scheme to detect and prevent grayhole attacks in various scenarios. We propose a secure routing framework based on elliptic curve cryptography digital signature algorithm (ECDSA) which can detect and prevent the grayhole attacks with improved performance. We take (Ad-hoc On Demand Distance Vector routing) AODV protocol for implementing our scheme and evaluating performance taking various performance metrics such as packet delivery ratio and throughput to show that our scheme resolve the grayhole attack with better performance.
G and P genotyping of bovine group A rotaviruses in faecal samples of diarrhoeic calves by DIG-labelled probes

The nucleic acid probes specific to genome segments 9 and 4 of bovine group A rotaviruses (BRVs) were developed for detection and determination of the G (G6 and G10) and P (P1, P5 and P11) types in field samples of diarrhoeic bovine calves. The type specific DNA probes were prepared by polymerase chain reaction amplification of hyper divergent regions of VP7 and VP4 genes from three genotypically distinct (G or P types) reference strains of BRV, viz. B223 (G10P11), NCDV (G6P1) and UK (G6P5), labelled with Digoxigenin (DIG). These G and P genotype specific DIG-labelled probes were evaluated for genotyping of rotaviruses of bovine origin directly in faecal samples. Of 308 calf diarrhoeic samples, 138 (44.81 %) were positive for BRV infection in nucleic acid hybridization assay, using VP7 and VP4 gene specific probes independently. Of probe positive samples (138), 112 were typeable by both G and P typing nested probes; 109 samples were typed as P11 (97.32%) and 3 as P1 (2.68%), and 97 as G10 (86.61%) and 15 as G6 (13.39 %). Surprisingly, none of the samples was typed as P5, indicating non-occurrence of P5 genotype among bovine rotaviruses in Haryana and adjoining areas of India. Furthermore, G10P11 was found to be the most prevalent combination among field rotavirus strains examined; whereas, G10P5 and G10P1 combinations were not reported in any of the samples.

Mediation in causal log-linear models

The analysis of the causality is important in many fields of research. To obtain the causal effects in a causal log-linear model I propose a theory, using the odds ratio and the concepts proposed by Pearl, whenever possible. I start calculating the effects in a simple mediation model where I analyze a new interaction effect, which I call cell. After I calculate the effects in a mediation model with two parallel mediators. If they are correlated, Pearl's theory cannot be used and no alternative theory has been proposed so far. To resolve this issue I present a new concept of causality. The mediation models are essential in the marketing, then to it, for a more complex analysis, I apply my causal theory.
Halogen and Hydrogen Bonding in Multicomponent Crystals of Tetrabromo-1H-Benzotriazole

4,5,6,7-Tetrabromo-1H-benzotriazole (TBBT) is still considered a reference inhibitor of casein kinase II (CK2), a valuable target for anticancer therapy, even though the poor solubility in water of this active pharmaceutical ingredient (API) has prevented its implementation in therapy. We decided to explore the interactions preferentially formed by TBBT in crystalline solids in order to obtain information helpful for the development of new TBBT cocrystals possibly endowed with improved bioavailability. In this paper, we describe the synthesis and the structural characterization of the TBBT methanol solvate and of the TBBT salt with N,N,N’,N’-tetramethylethylenediamine. It is shown that TBBT can give rise to several competing interactions. This API is clearly a good halogen bond (XB) donor, with bromine atoms adjacent to the triazole ring possibly better donors than the two others. TBBT is also a good hydrogen bond (HB) donor, with the triazole hydrogen forming an HB with the acceptor or being transferred to it. Interestingly, one of the triazole nitrogens was proven to be able to work as a hydrogen bond acceptor.
Influence of the Type of Mixture and Concentration of Different Binders on the Mechanical Properties of “Green” Charcoal Briquettes

The application of biomass to generate energy has been highly studied as an alternative to fossil fuels. In Brazil, there is a large production of orange juice, and their solid waste (bagasse) has as its main destination the production of food for ruminants. Therefore, there is an interest among the industries to transformed this waste into a by-product with higher benefit. In this way, this work has as main objectives, the use of a new type biomass to produce “green” charcoal and the application of three different types of binders (industrial cornstarch, pectin with high degree of esterification and pectin with low degree of esterification) using three different proportions (5, 10 and 15%) and two types of mixtures in way to verify which briquette has the lowest friability index a better compression resistance. To determine the friability index, the tumbling method was applied. The compressive strength of the briquettes was also determined. The binder that brought better characteristics to the charcoal briquettes, and therefore would be chosen for a production line is the industrial cornstarch. For this binder, the briquettes showed higher mechanical strength when applied the second mixing method. In this case, the briquette with a composition of 10 % of industrial cornstarch, presented characteristics as non-friable and withstand a pressure of 4.093 MPa in the compression tests. The choice of this binder is also because it is cheaper among the three tested ones.

Modulating Biocatalytic Activity toward Sterically Bulky Substrates in CO2-Expanded Biobased Liquids by Tuning the Physicochemical Properties

The study of CO2-expanded liquids using a green component such as a biobased solvent has been recently raised as a new concept for an alternative solvent and yet been largely unexplored in the literature for neither fundamental nor application studies. On the other hand, structural bulkiness of substrates remains one of the main limitations to promote enzymes as an efficient versatile catalytic tool for organic synthesis, especially biocatalysis in nonconventional solvents. Herein, we report a detailed investigation of CO2-expanded biobased liquids as reaction media for improved biocatalysis of sterically hindered compounds. We found that CO2 acts as a crucial trigger for various lipases to catalyze transesterification of challenging bulky alcohols in CO2-expanded 2-methyltetrahydrofuran (MeTHF). Furthermore, this study determines the physicochemical and transport properties of CO2-expanded MeTHF for the first time, which were then utilized for modulating biocatalytic activity. It was found that lipase ac.
Transcritical flow over a step

In both the ocean and the atmosphere, the interaction of a density stratified flow with topography can generate large-amplitude, horizontally propagating internal solitary waves. Often these waves appear as a wave-train, or undular bore. In this talk we focus on the situation when the flow is critical, that is, the flow speed is close to that of a linear long wave mode. In the weakly nonlinear regime, this is modeled by the forced Korteweg de Vries equation. We will review how Whitham’s modulation theory has been applied to obtain an analytical description of undular bores for flow over isolated obstacles, and then show how the same approach can be used for flow over a step.
Efficiency evaluation of urban and rural municipal water service authorities in South Africa: A data envelopment analysis approach

In recent years the local governments in South Africa have faced numerous public protests with regard to service delivery and particularly the provision of basic services such as water and sanitation. In response, South Africa has introduced benchmarking systems (Blue Drop, Green Drop) to improve the quality of potable water and sanitation services. These systems have seen some success; however, the efficiency with which these water services are provided is yet to be assessed. This study uses data envelopment analysis (DEA) to evaluate the efficiency with which several South African water service authorities (WSAs), including both metropolitan and local municipalities, provide water services to the public in both urban and rural areas.
A Review of Active Yaw Control System for Vehicle Handling and Stability Enhancement

Yaw stability control system plays a significant role in vehicle lateral dynamics in order to improve the vehicle handling and stability performances. However, not many researches have been focused on the transient performances improvement of vehicle yaw rate and sideslip tracking control. This paper reviews the vital elements for control system design of an active yaw stability control system; the vehicle dynamic models, control objectives, active chassis control, and control strategies with the focus on identifying suitable criteria for improved transient performances. Each element is discussed and compared in terms of their underlying theory, strengths, weaknesses, and applicability. Based on this, we conclude that the sliding mode control with nonlinear sliding surface based on composite nonlinear feedback is a potential control strategy for improving the transient performances of yaw rate and sideslip tracking control.
Productivity Spillovers and the Entry of Foreign-Owned Firms: The Case of Japanese Manufacturing Firms

This paper shows that in the short run an increase in foreign firms' industry share lowers the TFP growth of Japanese firms as a result of the decrease in market power. However, in the long run, the entry of foreign-owned firms has a positive effect on the productivity of local firms as a result of technology spillovers. In addition, the results suggest that foreign firms exert competitive pressure that forces Japanese firms with a high level of technological capabilities raise their productivity growth.

Application of ethyl formate as a postharvest fumigant for dry cocoa beans under a semi commercial trial

Fumigant toxicity of Ethyl Formate (EF) against four major cocoa storage pests was carried out on a semi commercial trial of two metric ton of cocoa beans under sheet without forced air circulation. The EF with concentration from 76-380 g LG1 were studied against pupae, larvae and adult of Cocyra cephalonica and Ephestia cautella (moth) and Tribolium castaneum and Lasioderma serricorne (beetles). These stored pests were inserted into a wire mesh tubes 6×1.5 centimeters (cm) and then arranged in a 25×2.5 cm polyethylene tubes and then inserted inside gunny sacks and exposed to the EF gas for 40 h with surrounding temperature and relative humidity (R.H.) recorded throughout the trial of 26±0.3-34±0.4°C and 65±0.4-91±0.2%, respectively. While, the temperature inside the tarpaulin was between 24±0.3-30±0.2°C and the R.H. as minimum of 42±0.4% and maximum of 63±0.3%. The result indicated that complete mortality for all stages of insects was detected at minimum concentration of EF (190 g LG1). Different stages and insect species gave difference response to the toxicity level of EF. However, the LC99 value for larvae and pupae of all stages of four insects tested showed no significant different among species except for adults of T. castaneum and L. serricorne. For LC50 value for larvae of L. serricorne, E. cautella and L. serricorne pupae are relatively more susceptible to EF than other two species. The estimated probit regressions were well fitted to the response as the chi-square values for larvae, pupae of four pest and two adults pests tested were not significant at 5% level of confident. The residue of EF was not found in whole beans, nibs and cocoa beans. As such the EF was successfully developed as a fumigant for treatment of pests control for dry cocoa beans.
