Distance, Throughput and Speed (DTS) Based Performance Analysis in Vehicular Ad Hoc Network Architecture

: The Vehicular Ad hoc Network is a collection of portable hubs framing a brief system on variable topology, working without a base station and without an incorporated organization. VANETs generally established as reliable networks in that vehicles use for communication reason on expressways or urban conditions. Due to limitation streets and rapid of vehicles directing is an issue in VANET. VANET transforms each vehicle into a remote hub, permitting vehicles about 100 to 300 meters of each other to associate and, make a system with a wide range. Be that as it may, in circumstances where hubs are mobile or when hubs frequently turn on and off, the nearby topology stays settled. Subsequently, it is important that every hub communicates its refreshed hub data to the greater part of its neighbour updates from the nodes known as beacons. Signals are communicated occasionally to maintain a precise neighbour list. In this paper performance evaluation is done based on distance, speed, throughput based beaconing schemes using network simulator.

Intracameral viscoelastic treatment for hypotony after glaucoma incisional surgery

We report on a minimally invasive treatment of symptomatic hypotony after glaucoma surgery. Hypotony after incisional glaucoma surgery can have severe visual consequences. Refractory symptomatic hypotony often requires surgical intervention to prevent further vision loss. The clinical records of four patients in this interventional case series with symptomatic hypotony and choroidal detachments after incisional glaucoma surgery between 2013 and 2014 were reviewed. Observations were made as the cases progressed. Visual obscuration secondary to refractory hypotony was treated with an intracameral injection of high-molecular-weight ocular viscoelastic devices (HMWOVD). Postinjection, mean intraocular pressure improved from a baseline of 3.6 mm Hg to 24.0, 15.5, and 9 mm Hg at 1 day, 1 month, and 6 months' post-intervention, respectively. The mean visual acuity after injection improved from 20/274 to 20/83 at 6 months. Choroidal detachments resolved within 1 week in all patients. Intracameral HMWOVD for the treatment of symptomatic hypotony post-incisional glaucoma surgery is minimally invasive, avoided reoperation, and led to quick visual recovery.

Analyzing Space Dimensions in Video Games

—The objective of this work is to analyze the role of space in video games, in order to understand how game space affects the player in achieving game goals. Game spaces have evolved from a single two-dimensional screen to huge, detailed and complex three-dimensional environments. Those changes transformed the player’s experience and have encouraged the exploration and manipulation of the space. Our studies review the functions that space plays, describe the possibilities that it offers to the player and explore its characteristics. We also analyze location-based games where the player’s position in game space is relative to his position in physical world. We saw in previous studies that there are more than one way to discuss space in games. Our understanding goes further and analyzes the game space in four aspects: gameworld, gameplay, player perspective and game view. Finally, we also propose an ontology to define the space characteristics
Relationship between family attitude, symptoms’ severity and social functioning of people suffering from schizophrenia over 20 years. A prospective study

Purpose: The aim of the study was to assess the relationship between the family attitude and clinical and social outcome measures in the group of 45 people diagnosed with schizophrenia during 20 years of illness. Methods: For the evaluation of clinical and social variables, the Anamnestic and Catamnestic Questionnaire, the BPRS scale and the scale of social functioning according to the DSM-III axis V were used. The family attitude during the first hospitalisation was measured with CFI. In subsequent measurement points, a 4-stage clinical scale based on the CFI categories (warmth and kindness, criticism, hostility, emotional overinvolvement) was used, which was then analysed as a dichotomous variable: favourable/unfa- vourable attitude. Results: A significant tendency to improve the family attitude within years of illness was observed. In women, the change in the fam- ily attitude was faster than in case of men. The unfavourable family attitude was associated with more frequent relapses and re-hospitalisations after 3 and 12 years after the first hospitalisation. The severity of symptoms and the level of social functioning were not related to the family attitude at any measurement point. Conclusions: In the community treatment program, during the 20-year course of schizophrenia, the unfavourable family attitude improved among both women and men, but beneficial changes occurred faster in women. Depending on the time of disease, there was a relationship between the unfavourable family attitude and more frequent relapses, re-hospitalisations and lack of connection with the severity of symptoms and the general level of social functioning.
Nickel Nanoparticle Arrays Prepared Using Nanosphere Lithography

The localized surface Plasmons (LSPs), supported by metal nanostructures find applications in wide range of sensors, vacuum nanoelectronic devices and for enhancing the efficiency of solar cells. The plasmonic properties solely rely on the size, shape and local environment of the metal nanostructures. For the production of nanometre scale periodic particle array (PPA), the nanosphere lithography (NSL) is demonstrated and presented in this article. Nanosphere Lithography (NSL) is simple, offers high throughput, cost-effective self-assembly nanofabrication technique capable of producing large variety of nanostructures and ordered nanoparticle arrays on any given substrates. The paper focuses on the synthesis of Nickel (Ni) nanoparticle arrays by nanosphere lithography technique. The characteristics of these nanoarrays are analysed using NSOM (ALPHA 100RAS) for AFM (atomic force microscopy) measurements. It is proposed to use this Self-Assembled Mask less Nanoparticle arrays to create nanocarbon emitter arrays by Cathodic Arc Deposition system. This nanocarbon emitter arrays are good field emitters and can be used for the development of Field emission electrical propulsion (FEEP) system for Nano satellites.
A progressive cardiac cine-MRI generation conditioned by disease diagnosis

A noticeable limitation on current methods for medical image synthesis is the presence of image artifacts that might alter the anatomical structure and generate images with misleading clinical interpretation. Additionally, existing approaches reproduce visual features and image similarities, often neglecting structure variations characterizing pathological patterns on living organs. Speciﬁcally, for cardiac cine-MRI sequences, the image artifacts might introduce severe changes in the morphological ventricles description. This work presents a progressive generative-adversarial network (PGAN) trained to produce MRI synthetic images conditioned to several heart conditions. Evaluation of the approach is carried out by using the generator model on a cardiac cine-MRI classiﬁcation task. The generator model is used to recover the embedding vectors from cine-MRI images by utilizing a backpropagation scheme. Then, the UMAP algorithm is applied to the embedding vectors to reduce the dimensionality of the representation further. The resulting visualization shows that the low-dimensional vectors could be easily grouped into diﬀerent heart conditions. Furthermore, using these low dimensional vectors to build a classiﬁcation model yields an average 0 . 8 accuracy on the heart condition classiﬁcation task of cine-MRI images.
Resilience of River Deltas in the Anthropocene

At a global scale, delta morphologies are subject to rapid change as a result of direct and indirect effects of human activity. This jeopardizes the ecosystem services of deltas, including protection against flood hazards, facilitation of navigation, and biodiversity. Direct manifestations of delta morphological instability include river bank failure, which may lead to avulsion, persistent channel incision or aggregation, and a change of the sedimentary regime to hyperturbid conditions. Notwithstanding the in‐depth knowledge developed over the past decades about those topics, existing understanding is fragmented, and the predictive capacity of morphodynamic models is limited. The advancement of potential resilience analysis tools may proceed from improved models, continuous observations, and the application of novel analysis techniques. Progress will benefit from synergy between approaches. Empirical and numerical models are built using field observations, and, in turn, model simulations can inform observationists about where to measure. Information theory offers a systematic approach to test the realism of alternative model concepts. Once the key mechanism responsible for a morphodynamic instability phenomenon is understood, concepts from dynamic system theory can be employed to develop early warning indicators. In the development of reliable tools to design resilient deltas, one of the first challenges is to close the sediment balance at multiple scales, such that morphodynamic model predictions match with fully independent measurements. Such a high ambition level is rarely adopted and is urgently needed to address the ongoing global changes causing sea level rise and reduced sediment input by reservoir building.
WAZIUP: Deploying Low-cost IoT for Developing Countries

Recent long-range radio technologies are promising to deploy Low Power WAN at a very low-cost for a large variety of IoT applications. However, even though, there are several issues that need to be addressed when considering deploying IoT solutions for low-income developing countries. In this article, we ﬁrst explain these issues and show how they can be addressed in the context of rural sub-saharan African applications. We then describe our low-cost, long-range IoT framework which takes cost of hardware and services as the main challenge to be addressed as well as ﬂexibility, quick appropriation and customization by third parties.
Comparison of Organic Farming and Conventional Farming In the Punjab, Pakistan

in our research, the comparative analysis between organic farming and conventional farming has been made to explore the agriculture economy in one of the provinces of Pakistan known as Punjab. Like other developing countries, Pakistan’s large portion of economy is also dependent upon agriculture. So it has also adopted the ways of organic farming to increase the production, reduction of poverty and raising economic wealth to make the backbone of Pakistan strong. Moreover, with the perspective of production but results are astonishing and opposite. Instead of modern cultivation, it has reduced pesticide disease and weed not to build. It is also beneficial for the soil to in the better form of utilizing the methods of organic farming, farmers still using conventional methods of farming. Reasons have been discussed in the following sections.To perform the results, two main cities of Pakistan has been taken; Lahore and Multan and self-administrated survey is conducted in the agriculture areas of both cities to collect the feedback from the farmers with respect to organic as well as conventional method of farming.A sample of 91 questionnaires of both methods is used to conduct survey and gather the opinions of farmers and people related to agriculture.Experiments show the larger use of conventional methods of farming in Pakistan as compared to organic methods. Results of this study depict the adoption of conventional farming as compared to organic farming in Punjab, Pakistan. There are several reasons behind it which are addressed in the part of discussion.
Latanoprost niosomes as a sustained release ocular delivery system for the management of glaucoma

Abstract Objective: Glaucoma is a leading cause of irreversible blindness worldwide. Whereas latanoprost is one of the most effective drugs in glaucoma treatment, its eye drops need frequent application leading to lack of patient adherence. This study aimed to develop a patient-friendly niosome-in-gel system for the sustained ocular delivery of latanoprost. Methods: Niosomes were prepared by the reverse-phase evaporation technique and optimized for different formulation parameters, such as cholesterol/surfactant and drug/surfactant ratios. Selected niosomal formulations were incorporated into different gels and their viscosity and drug release kinetics were evaluated. Optimal niosomal gel was evaluated in vivo in rabbits’ eyes for irritation potential and ability to reduce intraocular pressure. Results: FT-IR studies showed that there were nonspecific interactions between latanoprost and different niosomal components leading to drug encapsulation efficiency ≥88%. Latanoprost encapsulation efficiency increased with the drug/surfactant ratio and encapsulation efficiency ∼98% was obtained at a ratio of 50%. Pluronic® F127 had the best ability to sustain drug release from the niosomes. In rabbits’ eyes, this gel was free of toxic and irritant effects and reduced intraocular pressure over a period of three days, which was significantly longer than that of commercial latanoprost eye drops. Conclusion: Latanoprost niosomal Pluronic® F127 gel may find applications in glaucoma management.
Could bacteriophages isolated from the sewage be the solution to methicillin-resistant Staphylococcus aureus?

INTRODUCTIONS The emergence of multidrug-resistant bacteria such as Methicillin-Resistant Staphylococcus aureus (MRSA) complicates the treatment of the simplest infection. Although glycopeptides such as vancomycin still proves to be effective in treating MRSA infections, the emergence of vancomycin-resistant strains limits the long term use of this antibiotic. Bacteriophages are ubiquitous bacterial viruses which is capable of infecting and killing bacteria including its antibiotic-resistant strains. Bactericidal bacteriophages use mechanisms that is distinct from antibiotics and is not affected by the antibioticresistant phenotypes. OBJECTIVES The study was undertaken to evaluate the possibility to isolate bacteriolytic bacteriophages against S.aureus from raw sewage water and examine their efficacy as antimicrobial agents in vitro. METHODS Bacteriophages were isolated from the raw sewage using the agar overlay method. Isolated bacteriophages were plaque purified to obtain homogenous bacteriophage isolates. The host range of the bacteriophages was determined using the spot test assay against the 25 MRSA and 36 MSSA isolates obtained from the Sarawak General Hospital. Staphylococcus saprophyticus, Staphylococcus sciuri and Staphylococcus xylosus were included as non-SA controls. The identity of the bacteriophages was identified via Transmission Electron Microscopy and genomic size analysis. Their stability at different pH and temperature were elucidated. RESULTS A total of 10 lytic bacteriophages infecting S.aureus were isolated and two of them namely ΦNUSA-1 and ΦNUSA-10 from the family of Myoviridae and Siphoviridae respectively exhibited exceptionally broad host range against >80% of MRSA and MSSA tested. Both bacteriophages were specific to S.aureus and stable at both physiologic pH and temperature. CONCLUSION This study demonstrated the abundance of S.aureus specific bacteriophages in raw sewage. Their high virulence against both MSSA and MRSA is an excellent antimicrobial characteristic which can be exploited for bacteriophage therapy against MRSA.
Minimization of Call Congestion in Telecommunication Network Using OFDM Optimization Model

—The level of patronage being experienced in Global Systems for Mobile communication (GSM) in Nigeria is overwhelming. This is as a result of freedom of calling from anywhere at any time and clarity of the voice enjoyed since it is on a digital technology platform. As the number of subscribers continues to increase at a very high rate, there is a consequential increase in network congestion. Aftermath of this is the reduction in the quality of services delivered to customers. This paper, therefore, looked at the various causes of call congestions with special emphasis to Nigeria as well as possible solution approaches. The application of Orthogonal Frequency Division Multiplexing (OFDM) Optical Wireless Communications technique for GSM congestion reduction in Nigeria is proposed. OFDM was suggested for adoption because of its inherent advantages such as high spectra efficiency, cross talk elimination and simplified channel coding, etc.
LSHTM Research Online

Background: Musculoskeletal impairments (MSI) are a major global contributor to disability. Evidence suggests entrenched cyclical links between disability and poverty, although few data are available on the link of poverty with MSI specifically. More data are needed on the association of MSI with functioning, socio-economic status and quality of life, particularly in resource-poor settings where MSI is common. Methods: We undertook a case-control study of the association between MSI and poverty, time use and quality of life in post-conflict Myanmar. Cases were recruited from two physical rehabilitation service-centres, prior to the receipt of any services. One age- (+/ − 5 years of case ’ s age) and sex- matched control was recruited per case, from their home community. 108 cases and 104 controls were recruited between July – December 2015. Cases and controls underwent in-depth structured interviews and functional performance tests at multiple time points over a twelve-month period. The baseline characteristics of cases and controls are reported in this manuscript, using multivariate logistic regression analysis and various tests of association. Results: 89% of cases were male, 93% were lower limb amputees, and the vast majority had acquired MSI in adulthood. 69% were not working compared with 6% of controls (Odds Ratio 27.4, 95% Confidence Interval 10.6 – 70.7). Overall income, expenditure and assets were similar between cases and controls, with three-quarters of both living below the international LMIC poverty line. However, cases ’ health expenditure was significantly higher than controls ’ and associated with catastrophic health expenditure and an income gap for one fifth and two thirds of cases respectively. Quality of life scores were lower for cases than controls overall and in each sub-category of quality of life, and cases were far less likely to have participated in productive work the previous day than controls. Conclusion: Adults with MSI in Myanmar who are not in receipt of rehabilitative services may be at increased risk of poverty and lower quality of life in relation to increased health needs and limited opportunities to participate in productive work. This study highlights the need for more comprehensive and appropriate support to persons with physical impairments in Myanmar.
Coinfección HIV-HBV en regiones genómicas reguladoras

La coinfeccion con HIV y HBV es comun en virtud de que ambos virus comparten similares vias de transmision. La coexistencia de HIV puede modificar la historia natural de la infeccion por HBV favoreciendo la progresion a cronicidad y aumentando la tasa de replicacion de este. Estos eventos encuentran sustento en la potencial capacidad de modificar el accionar de elementos que regulan la expresion genica. Desde alli surge como objetivo principal de la presente tesis estudiar el impacto de HIV sobre la variabilidad y la evolucion molecular de HBV desde las regiones genomicas S, pol, preC/C y X a partir de pacientes cronicamente monoinfectados con HBV y HIV-coinfectados, estudiados longitudinalmente. El genotipo A2 de HBV resulto el mas prevalerte ante la coinfeccion. Sin embargo, comparativamente los aislamientos de tal genotipo caracterizados en pacientes monoinfectados mostraron mayor propension a cambios en regiones regulatorias. En linea con ello, la evolucion molecular de HBV exhibio diferentes tasas de evolucion asi como menor heterogeneidad y diversidad de cuasiespecies cuando HIV esta presente. Este estudio muestra por vez primera el impacto que le imprime la concomitante infeccion por HIV sobre diferentes parametros relacionados a la evolucion molecular del HBV.
A Fully Structure-Driven Performance Analysis of Sparse Matrix-Vector Multiplication

Sparse matrix-vector multiplication (SpMV) is an important kernel in many scientific, machine-learning, and other compute-intensive applications. Performance characteristics, however, depend on a complex combination of storage format, machine capabilities, and choices in code-generation. A deep understanding of the relative impact of these properties is important in itself, and also to better understanding the performance potential of alternative execution contexts such as web-based scientific computing, where the recent introduction ofWebAssembly offers the potential for low-level, near-native performance within a web browser. In this work we characterize the performance of SpMV operations for different sparse storage formats based on the sparse matrix structure and the machine architecture. We extract structural properties from 2000 real-life sparse matrices to understand their impact on the choice of storage format and also on the performance within those storage formats for both WebAssembly and native C. We extend this with new matrix features based on a "reuse-distance" concept to identify performance bottlenecks, and evaluate the effect of interaction between the matrix structure and hardware characteristics on SpMV performance. Our study provides valuable insights to scientific programmers and library developers to apply best practices and guide future optimization for SpMV in general, and in particular for web-based contexts with abstracted hardware and storage models.
