Optimal Power Allocation for Minimizing the Energy Consumption of a NOMA Base Station with Cell DTx

In this paper, we consider a base station that jointly employs Non-Orthogonal Multiple Access (NOMA) and Cell Discontinuous Transmission (Cell DTx) in order to reduce its power consumption and we study the problem of optimal power allocation. We show first that this problem is convex and can be solved using only single variable root finding algorithms. Then, we employ numerical simulations in order to assess the performance of the proposed power allocation.
Evaluation of Clinical and Oral Findings in Patients with Epidermolysis bullosa

Introduction: Epidermolysis bullosa (EB) is a genetically inherited disease characterized by recurrent bullae and erosions on the skin with numerous signs of dental caries and poor oral hygiene. The aim of this study was to investigate the general clinical and oral findings of patients with EB. Materials and Methods: In this prospective study, the clinical and oral findings and family history of 26 cases with EB were evaluated. The type of EB, gender, age, parental consanguinity, dental caries, oral findings, distribution of lesions and presence of associated anomalies, clinical and oral findings correlated with gender were recorded. Results: All 26 patients with EB had a history of consanguinity and siblings with EB to varying degrees. In our study, malnutrition, anemia and growth retardation, gastrointestinal system complications, hair thinning, hand and nail deformity, ocular problems and renal disease (in one case) were observed with variable frequencies. When the intraoral findings of the patients were investigated, extensive dental caries in all EB types, enamel hypoplasia in junctional EB (JEB) and the presence of tooth-root to be extracted in dystrophic EB (DEB), intraoral bullae and lesions, ankyloglossia, vestibular sulcus insufficiency, microstomia and maxillary atrophy were observed. Three cases had restorative treatment and one case had prosthetic rehabilitation. Conclusions: Oral involvement can be seen with varying frequencies depending on the type of EB and the severity of the disease. It may result from delayed oral and dental rehabilitation due to physical disabilities, limitations and more pressing medical problems. Microstomy, pain from mucosal lesions, and restricted access to the mouth can be caused by poor oral hygiene. Oral complications and caloric needs of individuals with EB should be determined, and individual prophylaxis should be applied to prevent caries formation and protect teeth.
Convection and total variation flow—erratum and improvement

This paper includes an erratum to “Convection and total variation ﬂow” [3], that deals with a nonlinear hyperbolic scalar conservation law, regularised by the total variation ﬂow operator (or 1-Laplacian), and in which a mistake has been written in the convergence proof of the numerical scheme to the continuous entropy solution. For correcting the proof, it is necessary to introduce an additional vanishing viscous term in the scheme. This modiﬁcation imposes that the whole paper be cast in the framework of discrete and continuous solutions with unbounded support. This new version shows nevertheless a better result than the previous one, since the BV regularity and the compactness of the support of the initial data are no longer assumed.
Inferences in semi-parametric fixed and mixed models for longitudinal discrete data

Longitudinal data analysis for discrete such as count and binary data has been an important research topic over the last three decades. With regard to inferences for this type of data, the marginal model approach using ‘working’ correlation based GEE (generalized estimating equation), and an auto-correlation class based GQL (generalized quasi-likelihood) approach have been used, among others. This later GQL approach was suggested because of certain efficiency drawbacks of the GEE approach. Many studies were also done using the GQL approach for longitudinal mixed models. In this thesis, we study the longitudinal count and binary data in a wider semi-parametric longitudinal fixed and mixed model setup. For inferences, the SQL (semi-parametric quasi-likelihood), SGQL (semi-parametric generalized quasilikelihood) and SML (semi-parametric maximum likelihood) have been used wherever appropriate. The asymptotic properties such as consistency of the estimators produced by these approaches have been studied in detail. We also study the finite sample properties of the new approaches and compare them where applicable with existing SGEE (semi-parametric generalized estimating equation) approaches. The proposed models and the estimation methodologies are also illustrated with some real life data.
Mycosis fungoides: Review and updates

Mycosis fungoides is the most common type of cutaneous T cell lymphoma. The early diagnosis of MF is still an area of debate and challenging issue due to its resemblance to chronic inflammatory dermatoses. Therefore, MF diagnosis is usually based on clinical-pathological correlation. Different lines of treatment are available for MF according to the disease staging
Nouvelle méthode d'analyse des interférences électromagnétiques (IEM) dans les convertisseurs statiques

Il est bien connu que la commutation des semi-conducteurs et leurs interactions avec les elements parasites lies a l'environnement est la source principale des perturbations conduites dans les convertisseurs d'electronique de puissance. Le developpement d'une methode simple, precise et rapide pour reconstruire ces perturbations constitue un defi majeur pour les concepteurs. Dans cet article, on propose une nouvelle methode de modelisation basee sur des fonctions de transfert partielles configurables (FTPCs). Cette methode permet, d'une part, une reconstitution tres rapide et precise des phases transitoires de la cellule de commutation et d'autre part l'identification des sources de perturbation dans la cellule de commutation. Un convertisseur equipe par des semi-conducteurs de technologie carbure de silicium SiC (MOSFET/Diode Schottky) est utilise pour la validation experimentale.
Changes in solubility and chemical speciation of potassium, calcium, and silicon in wood ash by acid treatment

ABSTRACT This study investigated the relationship between the solubility and the chemical speciation of plant nutritional elements (K, Ca, and Si) in wood ash treated with a dilute solution of sulfuric acid or phosphoric acid. The diluted acid solutions were added to fly ash (FA) collected from a power plant, and the untreated and acid-treated FAs were analyzed for their contents of K, Ca, and Si. The crystalline phases of the untreated and acid-treated FAs were identified using X-ray diffraction (XRD), and the Si species were determined using X-ray absorption near-edge structure (XANES) spectroscopy. Sulfuric acid and phosphoric acid treatments did not affect the solubility of K in FA. Water soluble and citrate soluble K in FA were decreased by the addition of these acids. The water soluble Ca content in FA treated with phosphoric acid did not show a significant change compared to that in the untreated FA, but it increased up to 65 times in FA treated with sulfuric acid. It is suggested that CaCO3, which was the main Ca species in the untreated FA, was transformed into syngenite and gypsum by the sulfuric acid treatment. Hydrochloric acid soluble Si in the acid-treated FA decreased compared to that in the untreated FA. In contrast, the NaOH-soluble Si fraction, a method for selectively extracting silica gel, increased especially in the phosphoric acid-treated FA. The results of XANES analysis showed that the FA samples treated with 10–30% sulfuric acid or 10–30% phosphoric acid had a lower degree of Si polymerization than the untreated FA, which corresponded generally to the increased Si solubility in FAs. However, FA treated with 30% sulfuric acid had lower soluble Si despite a lower degree of polymerization than FA, which was attributed to a lower pH. These results suggest that the change in solubility of Si in the acid-treated FA was influenced by the degree of polymerization and the decrease in pH. From the viewpoint of a fertilizer use of FA, sulfuric acid-treated ash, which consists of both water soluble Ca and citrate soluble Ca, is suitable for Ca fertilizer, and phosphoric acid-treated ash, which has high NaOH-soluble Si, is suitable for Si fertilizer
Upskilling of the School Heads in the New Normal

This study aimed to upskill the leadership competencies of school heads in Magallanes, Sorsogon, Philippines for the school year 2021–2022. This study employed the mixed-methods sequential explanatory design which outlined the quantitative and qualitative methods using the descriptive-survey method and interview to the purpose of this study. The results of a survey revealed the three highest ranks in terms of upskilling needs of school heads were mentoring and coaching, curriculum development, and management of educational projects. However, the interview transcript reveals that the upskilling for school heads significantly impacted all aspects of leadership development. The leadership training conducted using the upskilling design effectively improves the leadership competencies of school heads.
On-orbit polarization sensitivity evaluation of FY-3B MERSI

Medium Resolution Spectral Imager (MERSI) onboard FY-3 was a MODIS-like sensor which was designed for application in land, ocean and atmosphere. However, the prelaunch characterization of MERSI was not sufficient. The polarization property was not measured, which would influence the accuracy of sensor radiometric measurement, especially at scan edges. To evaluate the polarization sensitivity after launch, an ocean target based method was presented to model the Stokes vector entering the sensor at the top of atmosphere, and the on-orbit polarization response coefficients were estimated by regression between the modeled and measured radiance. After testing with Aqua MODIS, the method was applied to FY-3B MERSI. It revealed that there was relatively large polarization sensitivity for FY-3B MERSI visible bands. For the most sensitive band at 412nm, the polarization factor is approximately twice of that for Aqua MODIS. The mean polarization factors are above 3% for blue bands. For 412-nm band, the TOA polarization correction range is 16% for FY-3B MERSI, while 7% for Aqua MODIS on the same day.
Nonalcoholic liver disease: Epidemiology, risk factors, natural history, and management strategies

Nonalcoholic fatty liver disease (NAFLD) is now the most common chronic liver disease worldwide and a leading indication for liver transplantation in the United States. NAFLD encompasses a heterogeneous clinicopathologic spectrum, ranging from nonalcoholic fatty liver (NAFL) to nonalcoholic steatohepatitis, and progressive fibrosis, which can lead to end‐stage liver disease including cirrhosis and hepatocellular cancer. Predictive models suggest that over 100 million adults in the United States will have NAFLD by 2030, representing over a third of the population. In this manuscript, we provide an overview of NAFLD risk factors, natural history (including hepatic and extra‐hepatic outcomes), diagnosis, and current management strategies.
Biochemical and physicochemical properties of Persea americana fruits replacement for margarine on wheat-avocado cakes production on wistar rats

This research assessed the biochemical and physicochemical effect of Persea Americana fruits cake (PAFC) which served as a close substitute for margarine in Wistar rats. The animals were grouped into six of 5 rats each. Group A= received 100% Margarine and served normal as control, Group B= 20% Margarine+ 80% Avocado, Group C= 30% Margarine+ 70% Avocado, Group D= 40% Margarine+ 60% Avocado, Group E= 50% Margarine+ 50% Avocado, Group F= 100% Avocado only and all had access to clean drinking water ad libitum. The animals received these varieties of Persea Americana cakes for twenty one days. The results of the proximate composition of wheat-avocado cake showed that avocado cake contains higher carbohydrate, protein and fats. The carbohydrate content was highest in group F followed by group D It is also high in protein composition compared to group E D, B, and C. In spite that group F contain the highest amount of fiber followed by group D, C and E. More so, the moisture contents were higher in groups B and A respectively. The ash content were higher in group E and group A while the fat contents of group F has the least amount compared to groups E, C and A respectively. There were significant differences (P<0.05) between group A compared to other groups ranging from their percentage moisture composition to their percentage carbohydrate compositions. After the analysis, it was observed that the total cholesterol levels (TC-L) increased in all the test groups with group A recording the highest concentration. It was observed that the cakes have concentration of iron and sodium followed by calcium and magnesium. F (65.0±1.9)Mg/dl respectively. In the low density lipoprotein cholesterol (LDL-C) there was a decrease in the initial values obtained before treatment of the animals with the cake. Groups A, B, C, D and F decreased with the exception of group E. The order of decreased in their LDL-C are Groups D>F>B>C>A, while A increased. The (HDL-C) was also analyzed and it was discovered that their values increased significantly. Group B increased more than group C, F, A, D and E the one-way ANOVA shows no significance difference (P>0.05) within and among groups in the TC-level. In overall, the biochemical and the physico-chemical properties of wheat avocado study shows that wheat avocado cake is strongly important in the management of hyperlipidemia and could be used or substituted essentially for margarine or butter in the production/baking of cakes though the texture and the aroma were not as pleasant as the 100% margarine cake.
Kullback-leibler and renormalized entropies: Applications to electroencephalograms of epilepsy patients. Authors' reply

In a recent paper Quian Quiroga et al. [R. Quian Quiroga et al., Phys. Rev. E 62, 8380 (2000)] found renormalized entropy, formerly introduced as a complexity measure for the different regimes of a dynamical system, to beclosely related to the standard Kullback-Leibler entropy. They assure this finding by reanalyzing electroencephalographic data of epilepsy patients, previously examined by exclusive use of renormalized entropy [K. Kopitzki et al., Phys. Rev. E 58, 4859 (1998)]. We argue that the general considerations undertaken by the authors and the experimental results do not justify this conclusion.
Assessing The Impact of Medical Treatment and Fumigation on The Superinfection of Malaria: A Study of Sensitivity Analysis

Malaria is a disease caused by the parasite Plasmodium, transmitted by the bite of an infected female Anopheles. In general, five species of Plasmodium that can cause malaria. Of the five species, Plasmodium falciparum and Plasmodium vivax are two species of Plasmodium that can allow malaria superinfection in the human body. Typically, the popular intervention for malaria eradication is the use of fumigation to control the vector population and provide good medical services for malaria patients. Here in this article, we formulate a mathematical model based on a host-vector interaction. Our model considering two types of plasmodium in the infection process and the use of medical treatment and fumigation for the eradication program. Our analytical result succeeds in proving the existence of all equilibrium points and how their existence and local stability criteria depend not only on the control reproduction number but also in the invasive reproduction number. This invasive reproduction number represent how one plasmodium can dominate other plasmodium. Our sensitivity analysis shows that fumigation is the most influential parameter in determining all control reproduction numbers. Furthermore, we find that the order in which numerous intervention measures are taken will be very crucial to determine the level of success of our malaria eradication program.
The effects induced by the gamma-ray responsible for the threshold voltage shift of commercial p-channel power VDMOSFET

The variations in the threshold voltage shift in p-channel power VDMOSFET during the gamma ray irradiation was investigated in the dose range from 10 to 100 Gy. The investigations were performed without the gate bias and with 5 V gate bias. The devices with 5 V gate bias exhibit a linear dependence between the threshold voltage shift and the radiation dose. The densities of radiation-induced fixed and switching traps were determined from the sub-threshold I-V characteristics using the midgap technique. It was shown that the creation of fixed traps is dominant during the irradiation. The possible mechanisms responsible for the fixed and switching traps creation are also analyzed in this paper.

INTERRELATIONSHIP BETWEEN STOCK RETURNS AND SELECTED MACROECONOMIC VARIABLES: AN EMPIRICAL STUDY.

Arushi Gaur. The Indian Capital Market is said to be affected by various macroeconomic variables. The main purpose of this paper is to investigate the relationship between stock returns and two macroeconomic variables i.e. Exchange Rate and FII (Foreign Institutional Investment). Composite Index CNX Nifty has been considered as a proxy of Indian Capital Market. Dickey-Fuller Unit Root Test is applied to check the data for stationarity, Johansen Cointegration test has also been conducted to check whether the variables under consideration are cointegrated. Data was found to be stationary at first difference and variables were found to be cointegrated with each other. Since the variables are cointegrated, Vector Error Correction Model (VECM) has been used instead of classical Granger-Causality method and the results indicate that Exchange Rate Granger cause FII and Nifty both, and also FII Granger causes Nifty. No further causality was found between other variables. Copy Right, IJAR, 2013,. All rights reserved.
Molecular dynamics simulation on the effect of nanoparticle deposition and nondeposition on the nanofluid explosive boiling heat transfer

Abstract Molecular dynamics simulations were performed to investigate the effect of nanoparticle deposition and nondeposition on the explosive boiling heat transfer. Both particle state (deposition and nondeposition) and metal surface structure (smooth and rough) were considered to study the boiling behavior. Particularly for the rough surface, a special deposition case was simulated that the deposition nanoparticle was not filled with the pit. The results showed that the addition of nanoparticles enhanced the boiling behavior. The histories of argon temperature, net evaporation number, as well as heat flux demonstrated that deposition nanofluid boiling heat transfer enhancement behavior was the highest.
Service Selection Using Non-Functional Properties in MANETs

Mobile ad hoc networks are the ones which allow mobile nodes to spontaneously form a network and share theirservices. The dynamic environment of MANETs demands service selection should not only based on functional properties but also be driven by non-functional requirements. In this paper we present a modelling method of Non-Functional properties.The degree of impact of the property on QoS may vary. So, we allow the application designer to define weight for each property. The evaluation function for the properties cannot be uniform as the type of the property may be Boolean, string or numeric depending upon the nature of the property. Three different evaluation functions based on the type of the property have been defined. The sum of the weighted metrics is used to select theservices.
A fast total variation regularization algorithm for 2D piecewise constant radially symmetric functions

In this paper, we considered total variation regularization (TV regularization) for 2D radially symmetric piecewise constant (RSPC) functions. We obtained a system of equations solving the direct variational problem with the subgradient method. Using the system, we propose a Condat’s type algorithm for computation of an extremal function.
BV prox-regular sweeping process with bounded truncated variation

ABSTRACT This paper is devoted to the existence and uniqueness of solutions for perturbed sweeping process measure differential inclusions in infinite dimensional setting. The possibly unbounded moving set is prox-regular and controlled only through the truncated Hausdorff-Pompeiu distance. The normal cone involved is perturbed by a kind of Carathéodory mapping satisfying a time-dependent hypomonotonicity assumption on bounded sets. Various properties of the solution mapping are also provided.
A Stable Nonlinear Switched System for Landmark-aided Motion Planning

Abstract To guarantee navigation accuracy, the robotic applications utilize landmarks. This paper proposes a novel nonlinear switched system for the fundamental motion planning problem in autonomous mobile robot navigation: the generation of continuous collision-free paths to a goal conﬁguration via numerous landmarks (waypoints) in a cluttered environment. The proposed system leverages the Lyapunov-based control scheme (LbCS) and constructs Lyapunov-like functions for the system’s subsystems. These functions guide a planar point-mass object, representing an autonomous robotic agent, towards its goal by utilizing artiﬁcial landmarks. Extracting a set of nonlinear, time-invariant, continuous, and stabilizing switched velocity controllers from these Lyapunov-like functions, the system invokes the controllers based on a switching rule, enabling hierarchical landmark navigation in complex environments. Using the well-known stability criteria by Branicky for switched systems based on multiple Lyapunov functions, the stability of the proposed system is provided. A new method to extract action landmarks from multiple landmarks is also introduced. The con-trol laws are then used to control the motion of a nonholonomic car-like vehicle governed by its kinematic equations. Numerical examples with simulations illustrate the eﬀectiveness of the Lyapunov-based control laws. The proposed
On the Performance of the Layered-Division-Multiplexing using Maximal-Ratio Combining

This article proposes the diversity gain enhancement in layered division multiplexing (LDM) systems by applying maximal-ratio combining (MRC) technique. LDM systems is adopted as a baseline technology of the ATSC 3.0 systems which the two transmission layers are simultaneously transmitted over two different types of fading channels for fixed and mobile services. Hence, the performance analysis of each layer need to be evaluated on different type of fading channel. Starting with the moment generating function (MGF) of the MRC output signal-to-noise ratio (SNR), we propose the new method to derive closed-form expressions for average symbol-error rate (SER) of the proposed systems over Rayleigh and Nakagami- m fading channels in the presence of error propagation (EP) that is generated from the first layer detection. Analytical results show that the specific value of injection level at the transmitter need to be precisely defined to obtain the best mutual benefit for both LDM layers, and the proposed technique has significant performance advantage over conventional LDM systems. Simulation results demonstrate the tightness of the author’s analysis.
