Relation between ABO blood group and Helicobacter pylori infection among patients with peptic ulcer disease at Provincial Hospital: A cross sectional study

INTRODUCTION: To document the potential relationship between Helicobacter pylori infection (H. pylori), ABO and Rhesus (Rh) blood groups in affected individuals with peptic ulcer disorder. MATERIALS AND METHODS: This cross-sectional, research was accomplished from February 2021 to May 2021 among individuals experiencing dyspeptic conditions visiting Endoscopy Unit of Janakpur Provincial Hospital. All the patients were investigated for their blood group phenotype and Rhesus dependent through slide hemagglutination test. Also all the patients went through esophagogastroduodenoscopy (EGD) in order to identify peptic ulcer disease. Gastric biopsies were acquired and evaluated for H. pylori through urease test. RESULTS: A total of 103 patients were registered in this study, which included 49 males and 54 females with a mean age of 15-77 years. H. pylori was found positive in 75(72.8%) cases and negative in 28 (27.2%) cases, Blood group A, B, AB and O were found in 19.4%, 33.0%, 13.6%, and 34.0% of the patients respectively. Relatively higher prevalence of H. pylori was found in each blood groups O (33.3%) and B (33.3%) compared to blood group A (20.1%) and AB (13.3%). However, association of ABO blood group and prevalence of H. pylori was found to be insignificant (p=0.991). CONCLUSIONS: The study concluded that B blood group people were more prone to H. pylori infection. Our study revealed that H. pylori contamination was definitely an endemic issue, which needs to be handled by enhancing hygiene, supply of filtered water and in addition other measures for its elimination. Further meticulous studies are needed to establish relationship between blood type and H. pylori contamination in different age groups.
Chlamydomonas RABL4/IFT27 Mediates Phototaxis via Promoting BBSome-dependent Ciliary Export of Phospholipase D

Phospholipase D (PLD) interacts with the BBSome for loading onto retrograde intraflagellar transport (IFT) trains to exit cilia in Chlamydomonas reinhardtii. PLD ciliary retention and depletion of Rab-like 4 (RABL4) GTPase IFT27 cause the same non-phototactic phenotype but not impair IFT and ciliation. Here, we show that the IFT-B1 subunit IFT27 binds its partner IFT25 to form the heterodimeric IFT25/27 in an IFT27 nucleotide state-independent manner. IFT25/27, IFT-A, and IFT-B are irrelevant for maintaining the stability of one another. GTP-loading onto IFT27 enhances the IFT25/27 affinity for IFT-B1 in cytoplasm, while GDP-loaded IFT27 does not prevent IFT25/27 from entering and cycling through cilia by integrating into IFT-B1. Upon at the ciliary tip, IFT25/27 cycles on and off IFT-B1 and this process is irrelevant with the nucleotide state of IFT27. During BBSome remodeling at the ciliary tip, IFT25/27 promotes BBSome reassembly independent of IFT27 nucleotide state, making post-remodeled BBSomes available for PLD to interact with. Therefore, IFT25/27 facilitates BBSome-dependent PLD export from cilia via controlling availability of intact BBSomes at the ciliary tip, providing a regulatory mechanism for IFT27 to mediate phototaxis in C. reinhardtii.

An effective approach is developed for the solution of inverse kinematics task in analytical form for given end-effector position. A method for working space determination which uses numerical solution of forward kinematics task is presented.
A design method and computational architecture for generating and evolving building designs

The aim of this thesis is to contribute to the development of a practical evolutionary design approach — incorporating both design methods and software systems — that would allow a design team to evolve designs that they find surprising and challenging. This thesis has developed an overall framework that supports such an evolutionary design approach. Genetic and evolutionary algorithms and software systems attempt to harness the power displayed by natural evolution. These algorithms and systems have been successfully employed during the design process in a number of different design fields. However, they have been limited to tackling a very narrow range of well-defined engineering problems. Typically, the evolutionary system is used to optimise certain parameters within a predefined parametric design. Due to a number of fundamental problems, the evolutionary approach has had limited success in evolving the overall configuration and organization of complex designs. This thesis investigates and proposes how these problems can be overcome for building design. The primary problem to be overcome is generating designs that incorporate an appropriate level of variability, which is referred to as the variability problem. This affects both the performance of the evolutionary system and predictability of the types of designs that are produced. In an ideal system, performance is high and predictability is low. However, due to the variability problem, this is difficult to achieve. If design variability is very restricted, then performance may be high but predictability will also be high. If design variability is very unrestricted, then predictability may be low but performance will also be low. In order to evolve surprising and challenging designs, a system is required that both performs well and evolves unpredictable designs. The proposed generative evolutionary design framework allows the design team to restrict design variability by specifying the character of designs to be evolved. This approach is based on the notion of a design entity that captures the essential and identifiable character of a family of designs. This design entity is called a design schema. The design team encodes the design schema as a set of rules and representations that can be used by the evolutionary system. The system can then be used to evolve designs that embody the encoded character. The framework consists of two parts: a design method and a computational architecture. The design method consists of two phases: a generalization phase to develop and encode the design schema, and a specialization phase to evolve a specific design by using the encoded schema. In the first phase, the design team develops the schema with a type of design project in mind. However, the specific project does not yet need to be known. In the second phase, the schema is applied to a specific project and designs are evolved and adapted to the context and constraints of the project. One key advantage of this design method
Calculation method of overtaking sight distance for dual-lane highway

5 factors affecting the overtaking sight distance of dual-lane highway were analyzed from the view of safe driving. The running sketch map of overtaking car, overtook car and opposite car on dual-lane highway was designed. The mathematic model of calculating overtaking sight distance for overtaking car from beginning overtaking to finishing overtaking was established. The calculating parameters were defined such as braking distance and space headway on same lane etc, and the specific calculating formula of overtaking sight distance was proposed by means of mathematic analysis method. According to different design speeds and driving speeds, the overtaking sight distances of car and truck on dual-lane highway were calculated. Analysis result indicates that the overtaking sight distance of dual-lane highway is concerned with the design speed of highway, the overtaking speed of overtaking car, the speeds of overtook car and opposite car, and space headway on same lane. When the speeds of overtook car and opposite car are less than a half of overtaking speed, the calculated value of overtaking sight distance is just close to its specified value. Specified overtaking sight distance of dual-lane highway is smaller from safety view.
Linearization of power amplifiers in wide band communication systems by digital baseband predistortion technique

Today, new applications of radio frequencies are designed and proposed to provide more services to users. Spectrum resource becomes increasingly scarce due to an explosion of applications for new services. To achieve higher spectral efficiency, different non constant-envelop modulation techniques have been adopted in modern communication systems. The resulted signals become more sensitive to the nonlinearity presented in the transmission channel, particularly that of the power amplifier (PA). Moreover, in modern communication system, the bandwidth being more and more wider, the memory effects of PAs can no longer be ignored. To achieve higher efficiency, we need to work with average input power close to the compression zone by using additional devices to linearize PAs. The purpose of linearization techniques is to obtain a linear characteristic up to the saturation zone of the PA. One of the most promising techniques is the baseband digital predistortion technique due to its simplicity, flexibility, and reconfigurability. This technique inverts digitally the nonlinearity of the PA in baseband before the PA to get an overall linearized system. The objective of this thesis is to find some efficient baseband predistortion based linearization techniques (fast and simple to implement on digital cards), for the power amplifier with nonlinear memory effects.
Characteristics of optical flow from aerial thermal imaging, “thermal flow”

This study explores the utility of optical flow calculated from thermal imaging cameras, “thermal flow,” mounted on an aircraft for localization in day and night conditions. Our sensor implementation utilizes a long wave infrared (LWIR) micro sensor to capture sequences of thermal images and an on‐board computer to compute an optical flow estimate. We compared the performance of optical flow from the LWIR camera with the output of visible spectrum optical flow sensor. Flights were conducted spanning a 24 h window to explore how thermal flow performs relative to optical flow as the ground heats and cools. Agreement between optical and thermal flow was found during daylight when both sensors were functional. Additionally, thermal flow results were reliable in the middle of the day through to late evening, gradually degrading until shortly after sunrise.
Effect of Intestinal Microbiota on Brain Activity: ANN Analysis of Functional Magnetic Resonance Imaging

Modern biotope genomics has been able to determine the characteristics of each individual. The intestinal microbiota has a direct effect on the brain and behavioral activity of the individual. Any change in it modifies the mechanisms of emotional signaling, behavioral and visceral nociceptive reflexes. The resulting signaling mechanisms of the gut microbiota and probiotics including variations in microbiota production influence brain activity. Studies on rodents with reported vagal signaling in response to intestinal and probiotic pathogens. Diet, genetic factors, environmental factors may play a role in these alterations. The result is that is proven by functional brain imaging. The resulting effect of this interaction can be recorded in specific areas in the brain using functional magnetic resonance imaging. Depending on different biotopes in different people, levels of stress or relaxation are recorded. The analysis of these variations allows having an idea of the effect carried by each alteration in biotope and drugs administered to soothe stress for example. However, these effects are far from accurate. Human physiology is much more complex to draw hasty conclusions. If the effect is much more pronounced in women is that they are more emotional, sex is a factor to consider. In this study, we propose an intelligent system for analyzing these variables. The analysis of the MRI image is very complex due to it is a question of defining the exact contours of the activated brain zones. Given the complexity of the system, an artificial neural network analysis with deep learning is proposed. The constructed system is supervised learning. Input variables are (Biotope classification, genetic factor, diet factor, sex) and an output variable that expresses the degree of effect on activation of brain areas in relation to the centers of emotions recorded in functional fMRI. The established algorithm randomly introduces values ​​to the input factors of the system to read predict the emotional effect on the individual.
Strategic Planning and Performance Management: Theoretical Frameworks Analysis

This article presents these new strategic dictates in a critical form, examining the reasons that justify the striking interest being taken by researchers and managers, but also the limits of those principles, some intrinsic others that can be overcome by an integration with tradition. As a consequence, the article presents a framework which attempts to relate the constituent elements that distinguish the two main strategic theories and shows that both must be considered for strategic planning and performance management.
Development of a fabrication technology for integrating low cost optical interconnects on a printed circuit board

We present a fabrication technology for integrating polymer waveguides and 45° micromirror couplers into standard electrical printed circuit boards (PCBs). The most critical point that is being addressed is the low-cost manufacturing and the compatibility with current PCB production. The latter refers to the processes as well as material compatibility. Multimode waveguides are patterned by KrF excimer laser ablation in acrylate polymers with 0.13 dB/cm propagation loss at 850 nm. Single mode waveguides using inorganic-organic hybrid polymers show an attenuation loss of 0.62 ± 0.08 dB/cm at 1.3 μm. A process for embedding metal coated 45° micromirrors in optical waveguiding layers is developed. Mirrors are selectively metallized using a lift-off process. Filling up the angled via without the presence of air bubbles and providing a flat surface above the mirror is only possible by enhancing the cladding deposition process with ultrasound agitation. Initial single mode coupling loss measurements at 1.3 μm show an excess mirror loss of 1.55 dB. Multimode coupling loss measurements will improve this excess loss, because of the lower surface roughness of the mirrors using the acrylate polymers for multimode waveguides.
IDENTIFICATION OF POTENTIAL INFLUENCERS IN FACEBOOK USING NETWORK GRAPH METRICS

Social Media have been widely adopted by many businesses organizations. Social media sites like Facebook, Twitter are common phenomena for these companies to offer business services to their customers. Social networks are becoming a critical media for business and marketing. The amount of interaction generated at these sites are in the form like post, comments, Tweets, likes etc. influences the attitude and behavior of others. It is important to monitoring and identifying the potential influencer at these sites for better business opportunities and growth. For example, in the context of marketing on social networks, it is necessary to identify which users should be involved in an advertisement campaign. Each user is described by a large number of attributes, which transforms the problem of identifying relevant users in a needle in a haystack problem. It is important to quickly extract a limited number of meaningful characteristics that can be used to identify relevant users or potential influencers. Potential influencers may play a key role in the content dissemination and how users may be affected by different dissemination strategies. Network Graph Metrics such as Degree, Betweenness Centrality, Eigenvector Centrality, Clustering Coefficient, Closeness Centrality are used to identify the potential users in the social media networks. This paper presents a case study performed over a Facebook user with 250+ connections to explain how potential influencers are identified using Network Graph Metrics through visual representation. It is found those potential influencers are easy target for businesses to tap and keep them engaged for growth of their businesses.
Relationship between Temperature and Salinity Variations and the Fish Catch in the Egyptian Red Sea

Recently, the climate has been promptly changing, and ocean ecosystems are highly affected by this change (Hollowed et al., 2011). Marine researchers are keen to examine the relationship between climate change and fishery. Climate change and its associated phenomena, such as global warming and ocean acidification have turned to be serious issues in the ocean ecosystems. Hydrographical conditions are described as the physical parameters of seawater. This comprises seawater temperature, salinity, seawater density, depth, currents and turbidity. Those parameters are key players in the dynamics of marine ecosystems and can be altered by both anthropogenic activities and climate change, especially in coastal areas. Moreover, those conditions influence the production and the growth of plankton and fish species, and play an important role in the air-sea interaction processes, which impact the mixing process leading sometimes to a poor oxygenation of the seawater and sometimes to anoxic situations and a sudden mortality of some species.

After a brief recapitulation of the theory for WSSUS channels, methods are derived for using system and correlation functions for the examination of measured channel characteristics. The derived methods additionally lead to a simple interpretation of the relations between the functions. Finally results are given for the Time-Variant Impulse Response, the Scattering Function and the Time-Frequency Correlation Function calculated from measured data in an indoor environment
The Lithophile Element Budget of Earth's Core

The relative composition of Earth's core and mantle were set during core formation. By determining how elements partition between metal and silicate at high pressures and temperatures, measurements of the mantle composition and geophysical observations of the core can be used to understand the mechanisms by which Earth formed. Here we present the results of metal‐silicate partitioning experiments for a range of nominally lithophile elements (Al, Ca, K, Mg, O, Si, Th, and U) and S to 85 GPa and up to 5400 K. With our results and a compilation of literature data, we developed a parameterization for partitioning that accounts for compositional dependencies in both the metal and silicate phases. Using this parameterization in a range of planetary growth models, we find that, in general, lithophile element partitioning into the metallic phase is enhanced at high temperatures. The relative abundances of FeO, SiO2, and MgO in the mantle vary significantly between planetary growth models, and the mantle abundances of these elements can be used to provide important constraints on Earth's accretion. To match Earth's core mass and mantle composition, Earth's building blocks must have been enriched in Fe and depleted in Si compared with CI chondrites. Finally, too little Mg, Si, and O are partitioned into the core for precipitation of oxides to be a major source of energy for the geodynamo. In contrast, several ppb of U can be partitioned into the core at high temperatures, and this energy source must be accounted for in thermal evolution models.
A Frontal Thunderstorm With Several Multi‐Cell Lines Found to Produce Energetic Preliminary Breakdown

We combine electromagnetic measurements with meteorological and lightning detection data to explain an observation of unusually strong preliminary breakdown (PB) produced by a thunderstorm system that developed along the Mediterranean Coast of Southern France in the early hours of 19 June 2013. This multi‐cellular storm was composed of several parallel convective lines in the NW‐SE direction. Our analysis focuses on 10 sequences of energetic electromagnetic PB pulses recorded by two receivers located at different distances from this thunderstorm. The peak currents, which generated these strong PB pulses, reached −36 kA. The initial polarity of all observed energetic PB pulses confirmed the movement of the negative charge downward, as in case of PB pulses preceding negative cloud‐to‐ground discharges. The locations of PB pulses appeared in areas with none or very weak lightning activity. Most PB pulses were initiated in small, short‐living, rapidly moving convective storm cells characterized by low reflectivity values (generally <40 dBZ), weak vertical development, and low flash density. Our findings indicate that the observed thunderstorm might possess temporary strong negatively charged pockets located above a strong positive charge region at low‐level. Such charge arrangement, likely explains our observation of unusually strong PB pulses and the absence of RS pulses in electromagnetic recordings.
