Comparing Downlink Coordinated Multi-Point Schemes with Imperfect Channel Knowledge

Several linear transmit precoding and receive combining strategies with and without base station cooperation are compared to each other. The impact on sum-rate performance is shown with varying number of transmit and receive antennas, with different amounts of training and with varying receive power levels of the cooperating set. This is done by simulations in a two-user two-cell scenario. The limited scenario size helps to carve out the crucial parameters and show their interrelation with imperfect channel knowledge (CSI). These CSI imperfections are emulated based on a novel model, introduced in this paper. We show that imperfect CSI drastically reduces the relative coordinated multi-point (CoMP) gains over non-coordinated systems. The non-coordinated systems can already perform quite well, when multi-antenna terminals apply interference suppression strategies. Our results motivate that CoMP systems need to be studied under critical system assumptions, taking into account non-idealities, as they have a severe impact on the observed gains.

Negative attitude and lack of social support, particularly from friends and family, are considered the barriers to adherence and self-care. Objective: To assess the initial psychological reaction, attitude and social support in patients of Diabetes Mellitus Type 2. Materials and Methods: A community based prospective follow up study was conducted in rural and urban areas of Delhi. A total of 98 patients, either known diabetics or those after testing positive with blood-test during screening for diabetes, were selected after systematic random sampling and interviewed using pretested pre-designed questionnaire after 4 months of initial screening survey for diabetes. Data was analysed using SPSS software (version 16). Chi-square and fisher's exact tests were used and accepted statistically significant if P value was less than 0.05. Results: It was found that more rural patients (56, 88.9%) felt disappointed compared to those residing in urban areas (13, 61.9%), when their families denied them from eating prohibited diet (2=13.82, P=0.001). Rural families were reported to be more supportive for food and exercise issue (2=12.51, P=0.001). A higher proportion of patients in urban area (13, 41.9%) compared to rural patients (3, 4.5%) perceived that disease would affect their married life (2=22.15, P=0.001). However, no significant difference in negative attitude and social support was found during the gender, occupation and education status assessment. Conclusion: Psycho-social management of diabetes need to be targeted and addressed. Diabetes management programs should find ways to build and improvise social support for patients.

Application of Response Surface Methodology (RSM) for the Optimization of Ultrasound-Assisted Extraction (UAE) of Moringa oleifera: Extraction Yield, Content of Bioactive Compounds, and Biological Effects In Vitro

This study optimized ultrasound-assisted extraction conditions to maximize the extraction yield, total flavonoid content (TFC), total phenolic content (TPC), and DPP IV enzyme inhibitory activity from Moringa oleifera. The four UAE factors, solvent ratio (A), solvent–solid ratio (B), extraction temperature (C), and extraction time (D), were optimized using response surface methodology (RSM). A Box–Behnken design was used for the experimental design. The optimal conditions were found to be a 50% v/v solvent ratio, a 30% v/w solvent–solid ratio, 35 °C extraction temperature, and 45 min extraction time. The experimental value of extraction yield (R1), TFC (R2), TPC (R3), and DPP IV enzyme inhibitory activity (R4) (87.99% w/w, 56.63 mg QE/g extract, 97.26 mg GAE/g extract, and 93.32% inhibition, respectively) agreed with those predicted by RSM models (88.10% w/w, 56.61 mg QE/g extract, 97.16 mg GAE/g extract, and93.38% inhibition, respectively), thus demonstrating the appropriateness of the model used and the ability of the RSM to optimize the extraction conditions. Excellent DPP IV enzyme inhibitory activity was exhibited by M. oleifera compared with the standard, sitagliptin. While the modeled equation fits the data, the t-test is not significant, suggesting that the experimental values agree with those predicted by the RSM–BBD

Evaluation of submental approach for oro-endotracheal intubation in maxillofacial trauma

Introduction: In maxillofacial injuries, a choice has often to be made between different ways of intubation when surgical access to fractured nasal bone and simultaneous establishment of occlusion are required. We report our experience with submental intubation in the airway management of complex maxillofacial trauma patients and complication associated with it. The aim is to evaluate the outcome of airway management in patients with complex maxillofacial trauma by submental intubation. Materials and Methods: Fifteen cases reporting to the Department of Oral and Maxillofacial Surgery of a tertiary care hospital, with multiple facial trauma from September 2011 to September 2013 were selected for study. Median submental intubation was performed. Follow-up during hospitalization for wound associated complication and 3 months postoperatively was done. Results: At the end of the procedure, all 15 patients were extubated without any complications. Postoperatively, only one patient presented with superficial infection of the submental wound. Conclusion: Submental endotracheal intubation is a simple technique with very low morbidity and can be used as an alternative to tracheostomy in selected cases of maxillofacial trauma.

Effect of gravitation vector orientation relative to the solidification front on the micro- and macrohomogeneity of semiconductor crystals grown under terrestrial and space conditions

The influence of gravitation vector orientation relative to the solidification front on the dopant distribution micro- and macrohomogeneity in vertical oriented crystallization of highly Ga-doped Ge crystals has been investigated using computer simulation. The deviation of the axis for crystal growth relative to the g 0 vector, when a free surface of the melt is present, has been found to provide the formation of striations with a reduced dopant concentration. The influence of the solidification rate, convective and diffusion mass flows on the dopant distribution macrohomogeneity has been investigated.

Experimental Study on Proton Irradiation Effect of Gallium Nitride High Electron Mobility Transistor

As a third-generation semiconductor material, gallium nitride (GaN) has the advantages of high breakdown electric field, high electron saturation speed, high operating temperature and strong radiation resistance, and has broad application prospects in the aerospace field. As an important member of GaN-based electronic devices, GaN high electron mobility transistor (HEMT) is widely considered to be used in the power supply and other important systems of spacecraft. Therefore, GaN HEMT is of great significance for spacecraft to complete relevant setting tasks. However, GaN HEMT will inevitably be affected by space radiation environment when spacecraft perform related missions. Previous researches have shown that protons are the majority of high-energy particles in space environment. Therefore, relevant studies should focus on the effect of proton irradiation on the performance of GaN HEMT. Using 100 MeV high-current proton cyclotron, we investigated the proton irradiation effect of GaN HEMT, and proved the effect of proton energy on static electrical parameters of GaN. The research work in this paper lays a foundation for the future application of GaN HEMT in space missions.

(De)politicising and Ecologising Bicycles

Self-service bicycle systems are today being set up in a number of cities across the world. Seen as a means to promote a sustainable city and new forms of ecology, and valued for their 'planet friendly' character, these systems have become a hallmark for cities that want to become part of the so-called green culture. Drawing from the experience of the Vélib' programme in Paris and adopting a pragmatist perspective, this paper analyses the controversies which developed as this transportation infrastructure was implemented, as well as the definitions of 'ecology' which were at the centre of the dispute. In doing so it shows the capacity of the private firm involved in the system, JCDecaux, to 'hijack' and integrate the ecological critique, its rather powerful capacity to persuade other actors, and the popularity that the project achieved through a hard-won process of justification. At the same time, this paper argues that the mobility turn played a performative role in the justification and the definition of this new transport project.

Protecting of Marble Stone Facades of Historic Buildings Using Multifunctional TiO2 Nanocoatings

Stone surfaces and façades of historic buildings, due to their predominately outdoor location, suffer from many deterioration factors, including air pollution, soluble salts, relative humidity (RH)/temperature, and biodeterioration, which are the main causes of decay. In particular, the façades of the buildings deteriorate with direct exposure to these factors; deformation and disfiguration of superficial decoration and formation of black crusts are often observed on the stones. The development and application of self-cleaning and protection treatments on historical and architectural stone surfaces could be a significant improvement in the conservation, protection and maintenance of Cultural Heritage. A titanium dioxide nanoparticle has become a promising photocatalytic material, owing to its ability to catalyze the complete degradation of many organic contaminants and environmental factors. In this study, TiO2 nanoparticles, dispersed in an aqueous colloidal suspension, were applied directly to historic marble stone surfaces, by spray-coating, in order to obtain a nanometric film over the stone surface. The study started with an investigation of some properties of TiO2 nanoparticles, to assess the feasibility of the use of TiO2 on historic stone and architectural surfaces. Scanning electron microscopy (SEM) was, coupled with energy dispersive X-ray (EDX) microanalysis, (SEM-EDX), in order to obtain information on coating homogeneity and surface morphology, before and after artificial aging; the activity of the coated surface was evaluated through UV-light exposure, to evaluate photo-induced effects. The changes of molecular structure occurring in treated samples were spectroscopically studied by attenuated total reflection infrared spectroscopy (ATR-FTIR); activity of the hydrophobic property of the coated surface was evaluated by Sterio microscopy, model Zeiss 2010 from Munich, Germany, equipped with photo camera S23 under 80X magnification. The efficacy of the treatments was evaluated through capillary water absorption, and colorimetric measurements, performed to evaluate the optical appearance. Results showed that TiO2 nanoparticles are good candidates for coating applications on historic stone surfaces, where self-cleaning photo-induced effects are well evident; they enhanced the durability of stone surfaces toward UV aging, improved resistance to relative humidity (RH)/temperature and abrasion affect, reduced accumulation of dirt on stone surfaces when left in open air for 6 months, and did not alter the original features.

Impact of Wife's Employment upon Husband's Housework

The allocation of time is recognized as a major economic consideration for families. Analysis of longitudinal data on time use offers a fruitful method for examining change and/or stability in roles of husbands and wives. In this panel study of 1156 intact families, time allocation to housework and employment by husbands and wives follows a traditional pattern, with wives spending most time in housework and husbands spending most time in employment. Cross-lag analysis is used to examine the relationship between wife's labor force time allocation and husband's housework time. Basic patterns of time allocation predominate over the 6 years, with wife's employment time having very little impact on husband's housework time. Implications for families and for social policy are discussed.

Macrofaunal Community Structure Following the Restocking of Northern Quahog (Mercenaria mercenaria) to Great South Bay, Long Island, NY

Overharvest of the once highly abundant northern quahog, or hard clam [Mercenaria mercenaria (Linnaeus, 1758)], has decimated local populations on Long Island, NY, and the ecosystem services they provide. Among the potential ecological consequences of the loss of hard clams, impacts on benthic community structure and function have not been well documented. This study took advantage of a large-scale hard clam restoration effort by The Nature Conservancy in Great South Bay, NY, to investigate these parameters. The benthic communities between areas planted with high densities of adult clams (i.e., spawner sanctuaries) and adjacent sites with no transplants were compared. In clam-stocked areas, there were greater trophic and taxonomic group densities, especially for some environmentally sensitive groups such as crustaceans, and increased species richness, which in turn altered community structure of the resident infauna. Differences between paired sites for macrofaunal diversity and community structure were also observed, likely reflecting larger scale differences in invertebrate communities. Minimal differences were observed in sediment porosity, carbon and nitrogen content, and total organic matter between adjacent areas with and without clams, although all of these parameters were significantly associated with community structure. Although shell density was significantly higher in clam-stocked plots, it explained little of the variation in macrofaunal composition on its own or in combination with other environmental parameters, but in combination with the living clams may have added enough environmental complexity to enhance densities of different trophic groups. Within the short period of 3 y, differences in the benthic community with the presence versus the absence of clams were already detectable. More long-term data incorporating the effect of processes at multiple scales are needed to gain insight into the complexity of rehabilitating coastal benthic environments following the removal of important species such as clams. The results of this work support the notion that M. mercenaria acts as an ecosystem engineer, modifying the environment by creating habitat and enhancing the abundance of other species.

MEMBRANOUS TISSUE UNDER THE FLEXOR CARPI ULNARIS MUSCLE AS A CAUSE OF CUBITAL TUNNEL SYNDROME

Membranous tissue under the flexor carpi ulnaris (FCU), hypertrophy and fascia of the FCU were examined in 90 patients with cubital tunnel syndrome; it (submuscular membrane) was found in all patients, excluding five whose data were incomplete. Impressions on the nerve under the FCU were noted in 75 patients. In 43 patients, the submuscular membrane was judged to be the cause of neural compression. These 75 patients included 60 and 15 cases whose fascia of the FCU were judged to the thick and thin, respectively. Among the 58 with a thick submuscular membrane, 56 patients had an impression under the membrane. Fifteen patients had a flat impression on the nerve in the proximal compartment of the FCU, which was formed by ligamentous and bony floor and thick fascia of the FCU. It is believed that increased presure in the compartment is the cause of a flat impression. Slight compression of the nerve under the FCU with compressions in proximal and distal part of the nerve can cause symptoms of the nerve compression by multiple crush effect.

The influence of inter-firm relationships on Supply Chain Quality Management

Claims of the association between inter-firm relationships and the successful implementation of Supply Chain Quality Management (SCQM) practices have been long discussed in the literature. Nevertheless, these assumptions lack consistent empirical support. Using a quantitative survey approach of a sample of UK firms, this study offers a response to such void in the existing research and makes an attempt to empirically assess the impact of inter-firm relationships on SCQM practices. &#13;\nFindings show significant results for the association between the inter-firm relationships and SCQM. The findings present the practicing manager with two important recommendations: a need (i) to reconsider their supplier relationship management systems and (ii) to revisit their role in the implementation of quality systems across the entire supply chain networks. This study also offers the operations and supply chain management scholars an opportunity to re-examine the appropriateness of the theoretically-driven SCQM constructs for further empirical scrutiny.

ATTITUDES TOWARD MENTAL ILLNESS IN THE WORKING CLASS

By reviewing both the anecdotal and experimental data on attitudes toward mental illness and assessing the popularized cultural portrayal of this affliction, the authors have shown that the working class, per se, maintains a unique and characteristic response to such illness as differentiated from the middle class. Working-class people are likely to be authoritarian, less accepting of and more exclusionary toward those diagnosed as "psychologically sick," and subsequently less amenable to psychotherapeutic intervention than their more affluent counterparts. It is suggested that clinicians be sensitized to this empirical socioeconomic differential in attitude and as such monitor their service delivery approach accordingly.

Performance comparison of series and parallel DC power supply system

Since the structure of series DC power supply system, if any battery cell breaks down, the group of battery cells can't play its due role. The parallel DC power supply system has been successfully developed and applied in recent years. We want to know whether the parallel DC power system is worth vigorously popularizing and applying in the substation in the future? So we made a few special tests, and this paper will compare the series and parallel DC power supply systems with some data in some ways, such as performance, safety, reliability, maintenance quantity, convenience, economic benefits, etc.

Differentially Private Stochastic Linear Bandits: (Almost) for Free

In this paper, we propose differentially private algorithms for the problem of stochastic linear bandits in the central, local and shuffled models. In the central model, we achieve almost the same regret as the optimal non-private algorithms, which means we get privacy for free. In particular, we achieve a regret of O(T + 1) matching the known lower bound for private linear bandits, while the best previously known algorithm achieves O(1T). In the local case, we achieve a regret of O(1T) which matches the non-private regret for constant, but suffers a regret penalty when is small. In the shuffled model, we also achieve regret of O(T + 1) while the best previously known algorithm suffers a regret of O(1T3/5). Our numerical evaluation validates our theoretical results. Our results generalize for contextual linear bandits with known context distributions.

Network Error Logging: HTTP Archive Analysis

Network Error Logging helps web server operators detect operational problems in real-time to provide fast and reliable services. HTTP Archive provides detail information of historical data on HTTP requests. This paper leverages the data and provides a long term analysis of Network Error Logging deployment. The deployment raised from 0 to 11.73 % (almost 2,250,000 unique domains) since 2019. Current deployment is dominated by Cloudflare. Although we observed different policies, the default settings prevail. Third party collectors emerge raising the diversity needed to gather sound data. Even so, many service deploy self-hosted services. Moreover, we identify potentially malicious adversaries deploy collectors on randomly-generated domains and shortened URLs.
