Development of a Fresh Approach to Use Cooperative Diversity for Efficient & Effective Communication in Modern Wireless Systems

: Cooperative communication system for wireless mobile system is the most challenging and powerful technology for implementation in the mobile and wireless communication domain. Though, various protocols have been suggested for cooperative communication, but none of them is feasible in implementation because of attenuation, noise and cost. In this paper, all the systems used are incorporated by traditional mobile system with minimum changes, so that cost can be minimized. In the proposed approach we use a multiple input multiple output technique at receiver end to improve signal strength. Random data packets have been generated which have been modulated using QPSK technique and then passed through all types of attenuations and noises. The received packets were then analyzed in terms of signal to noise ratio (SNR) and symbol error rate (SER) [1]. It has been found that more than 5dB improvement has been achieved in comparison to traditional mobile system.
Simple programmable voltage reference for low frequency noise measurements

The paper presents a circuit design of a low-noise voltage reference based on an electric double-layer capacitor, a microcontroller and a general purpose DAC. A large capacitance value (1F and more) makes it possible to create low-pass filter with a large time constant, effectively reducing low-frequency noise beyond its bandwidth. Choosing the optimum value of the resistor in the RC filter, one can achieve the best ratio between the transient time, the deviation of the output voltage from the set point and the minimum noise cut-off frequency. As experiments have shown, the spectral density of the voltage at a frequency of 1 kHz does not exceed 1.2 nV/√Hz; the maximum deviation of the output voltage from the predetermined does not exceed 1.4 % and depends on the holding time of the previous value. Subsequently, this error is reduced to a constant value and can be compensated.
Seasonal Variation of Carbon Monoxide in Northern Japan: FTIR Measurements and Source-labeled Model Calculations SEASONAL

Tropospheric carbon monoxide (CO) was measured throughout 2001 using ground-based Fourier transform IR (FTIR) spectrometers at Moshiri (44.4 ° N) and Rikubetsu (43.5 ° N) observatories in northern Japan, which are separated by 150 km. Seasonal and day-to-day variations of CO are studied using these data, and contributions from various CO sources are evaluated using three-dimensional global chemistry transport model (GEOS-CHEM) calculations. minimum FTIR-derived tropospheric CO amounts occurred in April and September, respectively. The ratio of partial column amounts between the 0-4- and 0-12-km altitude ranges is found to be slightly greater in early spring. The GEOS-CHEM model calculations generally reproduce these observed features.

Effects of different annealing temperatures on the structures and magnetic properties of Co78.3B8.7Si13 alloy

Effects of different annealing temperatures on the and properties Abstract The structural analysis and magnetic properties measurement were conducted for Co 78.3 B 8.7 Si 13 alloy after annealing. Isochronous annealing at 713.15K (440ºC), 753.15K (480ºC), and 793.15K (520ºC) that are below crystallization temperature and at 833.15K (560ºC) that is around crystallization temperature affected the structure, magnetic properties and hardness of the Co 78.3 B 8.7 Si 13 alloy. It was found that crystallization was increase after annealing at various temperature. Crystallization temperature of Co 78.3 B 8.7 Si 13 metallic glass was determined by differential scanning calorimetry (DSC). It is around 835K (562ºC) but the glass transition temperature cannot be determined. Vicker’s hardness test showed a decrease in hardness for annealed samples. The magnetic force microscopy (MFM) images showed a decrease in magnetic domain structure in annealed samples. Magnetic susceptibility of as-cast sample and annealed samples were determined. A decrease in magnetic susceptibility for annealed samples were obtained. Hysteresis loops for as-cast and annealed samples indicated that annealing below and around crystallization temperature introduced a decrease in soft magnetic properties.
Epoxy/Graphene Nanocomposites: Problems Associated with Reaggregation

DMF is one the most commonly-used solvents for preparing graphene nanocomposites. Various processing variables for DMF are being used for the preparation of epoxy/graphene nanocomposites. Whilst the emphasis of all of these reported studies are on the improvements in mechanical, and other properties, of the epoxy/graphene nanocomposites, there is no study investigating how DMF affects the processing and how it is associated with the final properties of the nanocomposites. In this work, different dosages of DMF have been used to prepare nanocomposites. Mechanical testing, X-ray diffraction (XRD), dynamic mechanical analysis (DMA), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM) have been used to analyze the effectiveness of DMF dosage on the properties of processed nanocomposites. Larger dosages of DMF are not always ideal for dispersing graphene as it promotes reaggregation of graphene during the processing.
A RESEARCH STUDY ON FRACTIONATION OF SOCIAL BRAIN CIRCUITS IN AUTISM SPECTRUM DISORDERS IN MAYO HOSPITAL LAHORE

: Mental awkwardness Go-problem are developmental problems presented through prevention within social and corresponding boundaries and disturbing behavior. The consolidation of neuroscientific evidence has recommended that the neuropathology of the mental irregularities that constitute a problem is broadly scattered, including blocked accessibility by the cerebrum. Our current research was conducted in Mayo Hospital Lahore from August 2017 to September 2018. Here we evaluate the hypothesis that the diminished system poses a problem for ultra-modern adolescents with an imbalance near consequent adolescents within spatial express circles specific to social planning. Using a novel, holistically organized personality approach in valuable, appealing resonance patterns, we found that not only is accessibility between the areas of social cerebrum diminishing, nonetheless they remain similarly specific to the relationship among limbic ally associated cerebral areas associated with the abundance of sensory parts of social planning from different parts of communal cerebrum that provision language also sensorimotor systems. This specific model was self-managed for associations through degree of seriousness of social signs by recommending a fractionation of the social cerebrum in the mental one-sidedness that occurs at level of entire circuits.
Knowledge of diabetes, its complications of diabetes among Children with Type 1 diabetes mellitus

: Background : Low knowledge about diabetes risk factors coupled with high disease prevalence is common in low-resource countries. Type 1 diabetes mellitus (T1DM) is quite prevalent in the world, with a proportion of 1 in every 300 persons and steadily rising frequency of incidence of about 3% every year. More alarmingly, the incidence of T1DM among infants is also increasing, with children as young as 6 months succumbing to it, instead of that at a rather established vulnerable age of around seven and near puberty, when the hormones antagonize the action of insulin. The Kingdom of Saudi Arabia (KSA) is the largest country in the Middle East that occupies approximately four-fifths of the Arabian Peninsula supporting a population of more than 33.3 million people, of whom 26% are under the age of 14 years. As per the Diabetes Atlas (8th edition). Aim of the study : This study aimed to measure the extent to which parent are Knowledge of diabetes, its complications and prevention diabetes among Children with Type 1 diabetes mellitus.

with Naturally Occurring Allergy Ability to Produce IL-8 (CXCL8) in Animals IgE-Binding Monocytes Have an Enhanced

IL-8 is a potent chemokine that recruits neutrophils and basophils to promote inflammation in many species. IL-8 is produced by many cell types, including monocytes. In this study, we report a novel role for IgE-binding monocytes, a rare peripheral immune cell type, to promote allergic inflammation through IL-8 production in a horse model of natural IgE-mediated allergy. We developed a mAb with confirmed specificity for both recombinant and native equine IL-8 for flow cytometric analysis. Equine IL-8 was produced by CD14 + /MHC class II + /CD16 (cid:1) monocytes, including a subpopulation of IgE-binding monocytes, following stimulation with LPS. In addition, IgE cross-linking induced IL-8 production by both peripheral blood basophils and IgE-binding monocytes. IL-8 production was compared between healthy horses and those with a naturally occurring IgE-mediated skin allergy, Culicoides hypersensitivity. Allergic horses had significantly higher percentages of IL-8 + IgE-binding monocytes after IgE cross-linking. In contrast, frequencies of IL-8 + basophils after IgE cross-linking were similar in all horses, regardless of allergic disease, highlighting IgE-binding monocytes as a novel source of IL-8 during allergy. We concluded that IgE-binding monocytes from allergic individuals have an increased capacity for IL-8 production and likely contribute to the recruitment of innate immune cells during IgE-mediated allergy and promotion of inflammation during repeated allergen contact.

Legal Challenges in E-passport and Solution by BIO-PUF Function

Today many countries are utilizing electronic passports. In that authentication and confidentiality is very much essential. In the late 1990s, biometrics-based templates come as an authentication tool. Many biometric-based authentication protocols and RFID based authentication techniques have been suggested for authenticity and confidentiality. In this paper, the authentication protocol is developed with biometrics and Physical Unclonable Function (PUF). The concept of Bio-PUF is introduced, to combine the biometric concept with an unclonable response from PUF has been arrived for authentication. The protocol uses simple cryptographic operations, a strong PUF circuit, and any biometrics to create a more secure Bio-PUF based E-passport authentication protocol. This will provide more reliable security.
Optimal Selection of Multicomponent Matching Layers for Piezoelectric Transducers using Genetic Algorithm

One major problem in the design of ultrasonic transducers results from a huge impedance mismatch between piezoelectric ceramics and the loading medium (e.g. gaseous, liquid, and biological media). Solving this problem requires the use of a matching layer (or layers). Optimal selection of materials functioning as matching layers for piezoelectric transducers used in transmitting and receiving ultrasound waves strictly depends on the type of the medium receiving the ultrasound energy. Several methods allow optimal selection of materials used as matching layers. When using a single matching layer, its impedance can be calculated on the basis of the Chebyshev, DeSilets or Souquet criteria. In the general case, the typically applied methods use an analogy to a transmission line in order to calculate the transmission coeﬃcient T . This paper presents an extension of transmission coeﬃcient calculations with additional regard to the attenuation coeﬃcients of particular layers. The transmission coeﬃcient T is optimised on the basis of a genetic algorithm method. The obtained results indicate a signiﬁcant divergence between the classical calculation methods and the genetic algorithm method.
Prolongation of minimal action potential duration in sustained ﬁ brillation decreases complexity by transient destabilization Decreasing complexity of ventricular ﬁ brillation

: Aims: Sustained ventricular fibrillation (VF) is maintained by multiple stable rotors. Destabilization of sustained VF could be beneficial by affecting VF complexity (defined by the number of rotors). However, underlying mechanisms affecting VF stability are poorly understood. Therefore this study aimed to correlate changes in arrhythmia complexity with changes in specific electrophysiological parameters, allowing to search for novel factors and underlying mechanisms affecting stability of sustained VF. Methods & Results: Neonatal rat ventricular cardiomyocyte monolayers, and Langendorff-perfused adult rat hearts, were exposed to increasing dosages of the gap junctional uncoupler 2-aminoethoxydiphenyl borate (2-APB) to induce arrhythmias. Ion channel blockers/openers were added to study effects on VF stability. Electrophysiological parameters were assessed by optical-mapping and patch-clamp techniques. Minimal APD prolongation leads to transient destabilization of fibrillation, ultimately decreasing VF complexity, thereby providing novel insights into anti-fibrillatory mechanisms.
A motivated introduction to character sheaves and the orbit method for unipotent groups in positive characteristic

This article is based on lectures given by the authors in 2005 and 2006. Our first goal is to present an introduction to the orbit method with an emphasis on the character theory of finite nilpotent groups. The second goal (motivated by a recent work of G. Lusztig) is to explain several nontrivial aspects of character theory for finite groups of the form $G(F_{q^n})$, where $G$ is a unipotent algebraic group over a finite field $F_q$. In particular, we introduce the notion of a character sheaf for a unipotent group, and provide a toy model for the representation-theoretic notion of an L-packet.
Modelling and stress testing of the probability of default with the approach of robust regression

The potential impact of macroeconomic developments and crises scenarios on credit risk is not only from regulatory perspective, but also from an entrepreneurial point of view crucial for a rigorously and sales-oriented risk management. Basis of this thesis is a logistic regression model for the probability of default (PD) of a retail portfolio. The PD model on product level is evaluated and improved in terms of robustness and information criterion. The effect of different macroeconomic scenarios on the estimated PD is evaluated, using multivariate regression. The aim of the thesis is to identify and interpret macroeconomic risk drivers to recognize and manage credit risk in a timely manner.
Subjective and objective evaluation of one’s physical fitness – the role of self-esteem, motivation, and the need for social approval

Introduction and purpose of the work: Physical fitness is an important aspect of human life that can have an impact on biological, social, and psychological functioning. The aim of the research was to compare students who were engaged and those who were not engaged in sport in terms of self-evaluation of own physical fitness and performance in the Functional Movement Screen TM . The analyses also included the role of motivation, self-esteem, and the need for social approval. Material and method: The participants of the study were students who do sports ( n = 30) and those who are not engaged in a sport activity ( n = 30) at one Polish university (aged 18-24 years, M age = 21,23; SD = 1,5). The following instruments were used in the research: Self-Esteem Scale (SES), Social Approval Test (TAS-27), Sport Motivation Scale-II (SMS-II), Functional Movement Screen TM (FMS TM ), Survey about own physical fitness and sport related information. Results: The results revealed that active and inactive students differed in the subjective scores in the FMS TM and evaluation of own physical fitness. However, in both groups similar scores in self-esteem and the need for social approval were present. Subjective evaluation (made by the subjects) of own performance in the FMS TM was rated lower than objective one (made by the researchers) in both groups. The FMS TM scores (both objective and subjective) were related to different types of motivation. The lowest mean values were noted for external motivation and amotivation. Conclusions: The research has shown differences, in evaluation of physical fitness and FMS TM score - which can inform about the risk of potential injury - between the students who were engaged and those who were not engaged in sport. Motivation, need for social approval and self-esteem were mutually related. They can play an important role in shaping the belief about one's physical fitness and the effect of one's performance, although further investigations are needed as well as different types of statistical analyses to provide conformation for this assumption.
Is the News Deceptive? Fake News Detection using Topic Authenticity

—In this paper, we propose an approach for the detection of fake news in online social media (OSM). The approach is based on the authenticity of online discussions published by fake news promoters and legitimate accounts . Authenticity is quantiﬁed using a machine learning (ML) classiﬁer that distinguishes between fake news promoters and legitimate accounts . In addition, we introduce novel link prediction features that were shown to be useful for classiﬁcation. A description of the processes used to divide the dataset into categories representing topics or online discussions and measuring the authenticity of online discussions is provided. We also discuss new data collection methods for OSM, describe the process used to retrieve accounts and their posts in order to train traditional ML classiﬁers, and present guidelines for manually labeling accounts. The proposed approach is demonstrated using a Twitter pro-ISIS fanboy dataset provided by Kaggle. Our results show that the method can determine a topic’s authenticity from fake news promoters , and legitimate accounts . Thus, the suggested approach is effective for discriminating between topics that were strongly promoted by fake news promoters and those that attracted authentic public interest.

The Technology of the Cute Body

: This article considers the appeal of the cute body and its ambiguous relationship with the lovable. While cuteness is an aesthetic that is subjectively determined and expressed, it can also embellish a body with features that are standardized by systems of commodification. The cute body possesses a diminutive and vulnerable charm, but it is also an object that is augmented to solicit the subject’s love and control. Hence, the aesthetic of cuteness may seem to disempower the object, but it is likewise, an acute seduction that bears witness to the craft or technē that captures the subject. Developing a framework for cuteness as a stylistic device or technology embedded in the subject-object relationship, the article argues that the qualities and experience of the lovable constitute a condition of the affected subject, who must bear the paradox of embracing and effacing the object’s difference.
Predictors of outpatient follow-up care after adult emergency department asthma visits and association with 30-day outcomes

Abstract Objective: Guidelines recommend outpatient follow-up after emergency department visits for asthma, but factors related to rates of follow-up among the adult population are understudied. We sought to describe patient and community-level predictors of outpatient follow-up after an index ED visit for asthma and evaluate the association between outpatient follow-up visits and subsequent ED revisits.Methods: We conducted a retrospective observational cohort study of adult patients with emergency departments visits for asthma. The primary predictor was time to outpatient follow-up visit within 30 days of the index ED visit. The primary outcome was all-cause ED revisit within 30 days of the index ED visit. Cox proportional hazards regression was utilized to test the association between time to outpatient follow-up and hazard of ED revisit within 30 days.Results: Time to outpatient follow-up visit within 30 days was not significantly associated with hazard of 30-day ED revisit for asthma (HR 1.05; 95% CI 0.69–1.61). However, male patients (HR 1.45; 95% C 1.11–1.89) and smokers (HR 1.67; 95% CI 1.22–2.29) were significantly more likely to have an ED revisit.Conclusion: Younger, Black patients with Medicaid were less likely to receive follow-up care relative to older patients insured by Medicare. While follow-up visits were not associated with 30-day revisit rates, differences by age, race, and insurance status suggest disproportionate barriers to accessing care. Future research may target these subgroups to improve transitions of care after an ED visit for asthma.
