Protocol Wireless Medical Sensor Networks in IoT for the Efficiency of Healthcare

In this article, a new medical communication scheme, protocol wireless medical sensor networks for the efficiency of healthcare (PWMSN4EoCH), shorten by (PEH), which uses hasty strategy and random network coding (RNC), is proposed. The new concept improves the performance of the healthcare network. It quickly analyzes the medical network description, focusing on some basic parameters for narrowband Internet of Things (NB-IoT) systems in wireless mesh networks (WMNs). This PEH effectively meets the requirements prescribed for wireless telemedicine applications in which medical sensors (MSs) share the downlink and uplink resources to its neighborhood, including wireless health hubs (WHHs) and wireless base stations (WBSs) for controlling the health of the human body. The PEH scheme substantially accelerates the implementation devices of telemedicine for patient satisfaction. In contrast, the state-of-the-art technique (SoAT) scheme, which is currently used, misses the entirety of the proposed principle. The proposed scheme is compared with the SoAT in terms of message size (bytes), round-trip time (RTT) (ms), overall network capacity (ONC) (bytes/s, and delivery delay (DD) in ms. Our investigation has proved that the RTT, ONC, and DD of the proposed PEH are much better than the SoAT schemes, achieving 64%, 66%, and 71%, respectively. The simulation studies clearly indicate that the PEH introduces more than 64% performance enhancement over the SoAT scheme.
A model for analyzing water reuse and resource recovery potential in urban areas

Expansion and densification of urbanized areas can lead to increased pressure on an area’s water and wastewater infrastructure. This paper presents an optimization model using geographic information systems to locate potential sources and sinks of reclaimed water within an urbanized area. A mathematical solver then maximizes the water reuse using a set of constraints on mass balance, water quality, and electricity used for pumping. Three variations of the model are applied to Vancouver, British Columbia. The first scenario identifies a number of potential industrial sources and sinks for direct cascading with a total potential water savings of 133 400 m3/year. With the implementation of a satellite water reclamation facility in scenario 2, water recycling potential is increased to a maximum of 613 800 m3/year. Scenario 3 expands to include the non-industrial water users and the potential for water reuse is increased to a maximum of 969 200 m3/year.
On the calculation of specific contact resistivity on

In order to design submicrometer Si MOSFETs properly, the specific contact resistivity rho /sub c/ has to be controlled. The rho /sub c/ is known to be a function of both the barrier height and the Si surface doping concentration. An existing theory is used to generate rho /sub c/, emphasizing details in the practical regimes, with a careful choice of proper parameters such as the tunneling effective mass, which is a function of both temperature and doping concentration. >
Serving the Greater Social Good for Personal Gain: Effects of Polite Disagreements in Online Debates

Asynchronous, anonymous online debaters might be less likely than face-to-face debaters to value their public self-image (face), and thus disagree more freely. In this study, we examined whether polite disagreements (as opposed to rude ones) help online debaters win over audience members. An analysis of the most voted-on 100 political debates on Debate.org (200 debaters; 1,750 voters; 472,652 words) showed that debate initiators who used politer face-saving strategies to disagree (i.e., using expressions such as negatives with agree words rather than disagree or harsh rejection words) were more likely to receive more audience votes and win their debates. These results suggest that politeness tactics during online debates increase effectiveness, align with normative ideals, and yield pragmatic gain.
Emulating the directional sensitivity of fish hair cell sensor

This article describes the sensor development efforts that are inspired by the unique acoustic source tracking capability of aquatics such as fish. The physiological basis in the natural system has been attributed to the unique directional responses of hair cell sensor in the otolith. To emulate such directional transduction behaviors, a hair sensor based on piezoelectric microfiber is attempted. The sensor employs piezoelectric fiber both as the hair shaft and as the transduction element. A pair of electrodes was deposited on the fiber surface both for sensor signal collection and for polarizing the piezoelectric materials. Both computational modeling analysis and experimental study were conducted to validate the sensor performance. The hair sensor was found to possess directional responses that change in the pattern of a cosine function of the loading direction, resembling that observed in the hair cell sensor in the biological system. Such transduction behaviors pave the technical basis to emulate the unique acoustic tracking strategy by aquatics. PACS 07.07. Df, 07.10. Pz, 77.84. Cg, 87.19. lt
Annular Atrophic Lichen Planus: A Case Report

Annular lichen planus (ALP) is considered one of the rarest clinical variants of lichen planus (LP). It is characterised by a few annular lesions commonly seen on penis and scrotum or in intertriginous areas, and it is usually very resistant to therapy. Annular atrophic lichen planus (AALP) is considered as a distinctive subtype of ALP with histologically extensive elastolysis caused by lymphatic cells [1-2]. Classical dermoscopic criteria for LP diagnosis are missing, diagnosis is therefore challenging, and histological evaluation is needed [1].
Phases Quantification in Duplex Stainless Steels Weldments

Duplex Stainless Steels (DSS) are very attractive steels and their application is presently of increasing interest, especially as structural materials in aggressive environments. DSS are austeno-ferritic biphasic steels, having an austenite-to-ferrite phase ratio of about one, giving the best combination of mechanical and corrosion-resistance properties. However, these steels must be handled with extreme care, especially if thermal cycles are involved, owing to the formation of dangerous secondary compounds that highly worsen their excellent properties.The production of big pipes requires manufacturing welding operations on steel plates or sheets and the final products must satisfy specific requirements in terms of material properties. DSS approximately contain equal volume fraction of the phases that, in practice, cover a slightly wider range within 40/60 and 60/40. Therefore, since DSS properties depend on phase ratio, ferrite quantification on an industrial scale represents a topic of great interest, which must be as reliable as possible and, at the same time, quickly executable.The present paper gives a comparison of different methods currently employed for ferrite determination in DSS weldments, in order to understand the limits derived from the specific employed technique.
Full-Scale Test of Composite Frame under Large Cyclic Loading

This paper presents an experimental study on a steel moment frame with reinforced concrete (RC) floor slab that was subjected to horizontal cyclic loading leading to very large deformations. The primary objective of this test was to examine the interaction (composite action) between the steel beam and the RC floor slab. The steel beam moment capacity increased about 1.5 times in positive bending with the presence of the RC floor slab. During small beam rotations of 0.002–0.003 rad , the beam strength increased 1.2–1.4 times in negative loading, but composite action did not affect the negative beam moment capacity for larger rotations. The effective width estimated from the slab compressive force approximately equals the column width. Fracture at the bottom flange was notable due to the presence of the slab in the composite beam. Complete separation of the beam-to-column connections was not achieved even at a beam rotation of 0.13 rad , under which the composite connections still possessed bending resistan.
NLFE modeling of bond between NSM CFRP strips and heat-damaged concrete

Abstract A nonlinear finite element (NLFE) model was developed to describe bond behavior between heat-damaged concrete and near-surface mounted (NSM) fiber-reinforced polymer (FRP) strips. The different components of near-end pullout specimens were represented using proper elements in ABAQUS software with the cohesive element adopted to consider bond behavior. The model is calibrated using data from two published experimental works, before its predictions were extrapolated to consider the effect of temperatures (23–550 °C), along with the effects of concrete strength (25–55 MPa), bond length (100–350 mm), spacing (50–200 mm) and fiber type of NSM CFRP strips. Elevated temperatures, in excess of 300 °C, caused a reduction in residual pullout force, yet an increase in bond ductility. The degradation in bond was more pronounced for specimens with higher-grade concrete and lower spacing between strips. Exposing concrete blocks to 450 °C and above undermined the contribution of NSM CFRP strips (100–350 mm) to bond strength. The type of composite had a minor (if any) impact upon bond behavior between heat-damaged concrete and FRP strips for temperatures higher than 300 °C. The NLFE cracking patterns indicated that bond failure mode in the pullout specimens is dictated by the spacing between strips with minimal impact of exposure temperature or bond length.
Adaptive MIMO Detector Based on Hypernetwork: Design, Simulation, and Experimental Test

Algorithm unfolding, which provides a systematic connection between conventional model-based algorithms and modern data-based deep learning, has exhibited great empirical success for efficiently balancing the performance and complexity of multiple-input and multiple-output (MIMO) detectors. However, existing unfolding-based MIMO detectors have difficulties adapting to the high discrepancy in channel and noise conditions. In this study, we present a novel unfolding-based framework for MIMO detectors, which can automatically determine internal parameters of an unfolding-based MIMO detector to adapt to the varying conditions. A key part of our approach is to develop a hypernetwork that can effectively learn to generate the internal parameters in the sophisticated expectation propagation-based MIMO detector. In particular, we design long short-term memory-based hypernetwork to ensure the flexibility of the layers of the unfolded algorithm. The proposed framework is also extended to a coded MIMO turbo receiver to adapt to the different feedback beliefs from the decoder. Numerical results demonstrate that the proposed MIMO detectors have excellent adaptation capability to different channel environments and noise levels. Compared with the existing unfolded algorithm that is an optimal reference, the proposed framework avoids frequent retraining and presents the nearly optimal performance in uncoded and coded MIMO systems. An over-the-air platform is presented as well to demonstrate the significant robustness of the proposed receivers in practical deployment.
From strong to exact Petri net computers

Petri net paradigm of computing is concerned discussing basic types of Petri net computers and their relations. We developed a technique of parametric specification of Petri nets, built of a few connected components which are repeated depending on a parameter or a set of parameters, and composition of software to generate automatically the corresponding models in a vivid graphical form. We construct explicitly a Petri net that is a strong computer of double exponent after R.J. Lipton. Its nondeterministic computation is represented by a Petri net reachability graph to which a successful branch belongs. Then we minimise and transform the net to obtain twice smaller construct than the original one. Moreover, the obtained net possesses such a marvellous property that addingto it four priority arcs makes it an exact (deterministic) computer having a single firable sequence only. Same as the Lipton’s net, the minimized net allows the proof that the Petri net reachability problem is exponential in space. Besides, it represents an example when simple transformations allow guessing the successful branch of a nondeterministic computation. The practical significance of the approach in applications consists in a state-of-art heuristic technique of solving some NP problems in polynomial time.
TopoFun: a machine learning method to improve the functional similarity of gene co-expression modules

Abstract A comprehensive, accurate functional annotation of genes is key to systems-level approaches. As functionally related genes tend to be co-expressed, one possible approach to identify functional modules or supplement existing gene annotations is to analyse gene co-expression. We describe TopoFun, a machine learning method that combines topological and functional information to improve the functional similarity of gene co-expression modules. Using LASSO, we selected topological descriptors that discriminated modules made of functionally related genes and random modules. Using the selected topological descriptors, we performed linear discriminant analysis to construct a topological score that predicted the type of a module, random-like or functional-like. We combined the topological score with a functional similarity score in a fitness function that we used in a genetic algorithm to explore the co-expression network. To illustrate the use of TopoFun, we started from a subset of the Gene Ontology Biological Processes (GO-BPs) and showed that TopoFun efficiently retrieved genes that we omitted, and aggregated a number of novel genes to the initial GO-BP while improving module topology and functional similarity. Using an independent protein-protein interaction database, we confirmed that the novel genes gathered by TopoFun were functionally related to the original gene set.
Documenting Parental Refusal to Have Their Children Vaccinated

Despite our best efforts to educate parents about the need to vaccinate their children through discussions of vaccine-preventable diseases, the effectiveness of vaccines in preventing them, and the realistic chances of vaccine-associated adverse events, some will decline to have their children vaccinated. The incredible success of immunizations in dramatically reducing the incidence of vaccine-preventable diseases has led to an increased public focus on vaccine safety. Even though scientific data and doctors solidly support the fact that vaccines are safe and effective, research on hypotheses about harmful side effects often is taken out of context. Safety concerns, some appropriate and many inappropriate but widely discussed in the media and on unmonitored and biased Web sites, cause substantial and often unrealistic fears.
Quantum transport modeling in nano-scale devices

We present results and describe progress we have made in the development of our quantum transport modeling for nanoscale devices. Our simulation is based upon either the nonequilibrium Green's function method (NEGF) or the quantum correction (QC) associated with the density gradient method (DG) and/or the effective potential method (EP). We show the results of our modeling methods applied to several devices and discuss issues faced with regards to computational time, open boundary conditions, and their relationship to self-consistent solution of the Poisson-NEGF equations. We also discuss those for efficiently tailored QC Monte Carlo techniques.

CAMEL Rating System and Financial Performance of Islamic Banks in Kenya

Kenyan Islamic banks are facing a myriad of credit risk issues adversely affecting their financial performance. Importantly. CAMEL rating system has been identified as an effective approach when making credit risk management decisions. However, most of the research associating financial performance of Islamic banks has ignored issues arising in emerging market such as Kenya, a knowledge gaps this research locked. Quantitative approach was utilised while adopting correlational research design. The research had its target population as being the three (3) Islamic banks which had been operating in Kenya between the year 2012and 2020 where census was employed. The researcher compiled financial data from secondary data for between 2012 and 2020. Quantitative analysis approach was applied in the analysis to yield respective statistics; descriptive and inferential. The study concludes that; capital adequacy has a statistically significant positive, assets quality has a statistically significant negative, management efficiency has a statistically significant positive, earnings ability has a statistically significant positive, and liquidity has significant negative, effect on financial performance of Islamic banks in Kenya. Accordingly, CAMEL rating model is appropriate for assessing financial performance of Islamic bank in Kenya. The study recommends that the Kenyan Islamic bank, should employ the optimal investment strategy for capital adequacy determination, manage their assets, enhance their management efficiency capability, improve their earnings ability, and strictly adhere to recommended liquidity levels. The research recommends that Kenyan IBs should be employing CAMEL rating model on yearly basis to identify elements requiring special attention.
The fuzzy front end of product development: an exploratory study

The aim of this paper is to describe front-end activities in practice and get first hints for effects of the front end on project outcome and the meaning of contextual factors. The results of an exploratory study of fourteen product development projects are contrary to the wide-spread opinion that the quality of execution of front-end activities in practice is low. Although, due to the small sample size, our findings are limited, there seems to be an indirect impact of the fuzzy front end on project outcome: Front-end activities may reduce deviations during the following development phase. Furthermore, company size and the degree of newness of a project to a firm seem to have an influence on the fuzzy front end. Therefore, for future research, we suggest large-scale studies which examines direct and indirect effects and consider contextual factors, e.g., by evaluating structural equation models.
Property graphs and paths in GQL: Mathematical definitions

This paper provides precise mathematical definitions of a property graph as specified in the proposed GQL international standard, which is an attributed mixed multigraph with loops. It further defines a partially-oriented walk in such a property graph, which is called a path in GQL, as well as restricted classes of such walks (trails, simple/acyclic paths).
Vitexin Anew Antihypertensive Drug (Isolated from prosopis farcta [Iraq endogenus] plants)

Vitexin was isolated and identified from pods of prosopis farcta (Iraqi endogenous). In vitro and in vivo cardiovascular actions of vitexin were studied. Vitexin produced positive inotropic effect which was not related to B1 adrenergic receptor activation. Vitexin has a vasodilator activities and it could reverse thevasoconstrictor response of isolated pulmonary artery to potassium chloride and phenylphrine. Vitexin has produced a significant increase in ejection fraction in volunteers with mild heart failure. Also vitexin has produced a significant increase in urinary flow and urinary sodium and potassium excretions in healthy and mild hypertensive volunteers, it’s significantly reduced mean arterial blood pressure of the mild hypertensive volunteers. The positive inotropic effect of vitexin is most properly related to the inhibition of phosphodiesterase enzyme by vitexin. The vasodilator activities of vitexin could be mostly associated to the increase in cGMP (attributed to phosphodiesterase inhibitory effect of vitexin) and the activation of K+-channels. The diuretic effects of vitexin could be attributed to the inhibition of Na-Cl symporter system in the renal distal tubule. The most likely mechanisms of action of vitexin as a hypotensive compound are through its vasodilator and diuretic effects. So this agent could be a best new antihypertensive drug compared with present antihypertensive drugs which are in the market now. In addition to that vitexin can be used in heart failure as cardiotonic drug
Design considerations for high packaging density optical bus array

In this paper, a crosstalk model is developed to study the packing density and interconnect distance limitations of an optical interconnect system employing polymer-based single-mode bus arrays. The upper limit of channel packing density (1250 channels/cm at interconnect distance of 5 cm) is determined for the first time using the crosstalk model, in which channel cross-coupling among an infinite number of waveguides is considered. Computer simulations are provided together with the proven experimental results. It is shown that there is a threshold of channel separation due to channel cross-coupling, which results in a tradeoff between channel packing density and interconnect distance. Waveguide dimension closer to the cutoff boundary of second mode (E12X) is preferred for an optimum design.
Extended optical fiber line testing system using L/U-band crossed optical waveguide coupler for L-band WDM transmission

We proposed an extended optical fiber line testing system using ultra-low-cost crossed optical waveguide couplers with L/U-band thin dielectric film filters for L-band WDM transmission. We described the design of the return loss required for optical filters located in central offices. We also designed and confirmed the effectiveness of the configuration of a crossed optical waveguide coupler and a thin dielectric film filter with a steep optical spectrum to separate a 1650 nm test light from L-band wavelength light. We confirmed that there was no degradation in the OTDR trace caused by multi reflections at optical filters when using our crossed optical waveguide coupler.
