Chemical Composition and Physical Properties of Some Egyptian Cucurbitaceae Seeds and Oils

The current study was intended to evaluate the chemical composition, functional properties, and physical properties of some cucurbits seed. Chemical composition, functional properties of sweet melon (Cucumis melo var. reticulatus), sweet melon (Cucumis melo var. aegyptiacus) watermelon (Citrullus lanatus), citron melon (Citrullus lanatus var. Colocynthoides). Pumpkin (Cucurbita maxima), and summer squash (Cucurbita pepo), were studied as well as the characteristics of their seed oils. The seeds are rich in protein, crude fat, and crude fiber. The seeds contained high amounts of K, Mg, Na, Fe, and Mn. Water and fat absorption capacities, emulsification properties, and foam stability were fairly good in all seeds. Data obtained for the oils’ characteristics agree well with those of other edible vegetable oils. The obtained results revealed that the seeds presented an alternative source of vegetable oil. Seeds could be added to food systems such as bakery products.
Comparison of respiratory pathogen colonization and antimicrobial susceptibility in people with cystic fibrosis versus non cystic fibrosis bronchiectasis: A systematic review

Background Both cystic fibrosis (CF) and non-cystic fibrosis bronchiectasis are characterized by permanent bronchial dilation, leading to impaired mucociliary clearance and development of chronic infections. Although the core airway microbiota in both CF and non-CF bronchiectasis may be similar, particular satellite microbes are associated with specific conditions. Moreover, there are several factors, which may be responsible for the disparity in antibiotic susceptibility profile between the CF and non-CF populations. Hence comparing the microbiota and antibiotic susceptibility pattern in CF bronchiectasis with non-CF bronchiectasis would aid in improved management of both the conditions. Methods Two authors will independently search the electronic databases PubMed and EMBASE for studies reporting bacterial colonization of the respiratory tract determined by examination of any respiratory tract specimen, by conventional bacterial culture or specialized techniques; and/or antimicrobial susceptibility testing in adults and children diagnosed with bronchiectasis in either CF subjects or non-CF subjects. The authors will independently assess the risk of bias for each included study using the Newcastle Ottawa Scale (NOS). We will present the data with descriptive statistics and provide pooled estimates of outcome parameters, wherever it is feasible to perform meta-analysis using a random effects model. Heterogeneity in studies will be explored by visual inspection of forest plot as well as using the Higgins and Thompson I2 method. We will contact the corresponding authors of studies where data is/are missing and try to obtain the missing data. Discussion To date, there are no locally applicable evidence-based guidelines for antimicrobial treatment of non-CF bronchiectasis patients. In general, treatment in non-CF bronchiectasis is based on extrapolation of clinical trials done in subjects with CF bronchiectasis. An insight into the microbiota and antimicrobial susceptibility patterns against specific organisms in both the conditions would facilitate appropriate rather than empiric therapy, and hopefully reduce the burden of antimicrobial resistance created by rampant usage of antibiotics. Therefore, this systematic review is being undertaken to compare the respiratory tract colonization and antibacterial susceptibility pattern in people with cystic fibrosis versus non-cystic fibrosis bronchiectasis. Systematic review registration: The protocol was submitted for publication in PROSPERO on June 26, 2020 (PROSPERO ID: 193859).
Current practices of management of congenital Cytomegalovirus infection during pregnancy and childhood: systematic review protocol

Background: Congenital CMV infection is the first worldwide cause of congenital viral infection and a major cause of sensorineural hearing loss and mental retardation. As systematic screening of pregnant women and newborns is still debated in many countries, this systematic review aims to provide the state of the art on current practices concerning management of congenital CMV infection.Methods: We will perform electronically searches on MEDLINE, EMBASE, Cochrane Library (CENTRAL), ClinicalTrials.gov, Web of Science and hand searches in grey literature. Interventions regarding biological, imaging, and therapeutic management of infected pregnant women, fetuses and neonates/children (from birth to 6 years old) will be studied in this systematic review. Study screening will be performed in duplicate by two independent reviewers and risk of bias will be evaluated with the ROBINS-I tool. Discussion: This review will provide the state of the art of current management of congenital CMV infection in pregnant women, fetuses, neonates and children until 6 years old, in order to have an overview of current practices of congenital CMV infection.Systematic review registration: PROSPERO CRD42019124342
M-Commerce, Sales Concentration, and Inventory Management

Problem definition: The mobile commerce (m-commerce) channel is poised to be the future of online markets. It offers search features distinct from conventional personal computer (PC)-based e-commerce channels. Its easy accessibility extends the time available for customers to search, although its shopping environment constraints (e.g., small screen size, single-tab browsing) may inflate search costs. Collectively, these competing features cause ambiguity about the mobile channel’s true effect on sales concentration—a key criterion in managing retail operations. The focus of this study is to understand the net impact of the mobile channel on driving sales concentration. Academic/practical relevance: Our study extends the empirical literature focusing on online retailers’ channel strategies and their implication on operations practice. It examines differences in primary online channels—mobile and PC—on shaping sales concentration across products and the cost of ignoring such a difference on inventory management, a core decision for operations managers. Methodology: We collaborate with a large online apparel retailer to access customer-level transactional data. We identify the mobile channel’s effect on sales concentration using a difference-in-differences strategy that leverages a quasi-experiment stemming from the retailer’s decision to discontinue its PC sales channel. Results: We find that the mobile channel increases the share of popular products by 6.4% compared with the PC channel. We also identify scenarios where ignoring this significant sales concentration difference will yield suboptimal inventory stocking by 4.2%–12.9%. Managerial implications: Our paper highlights that the mobile and PC channels have different sales concentrations because of different search features. Ignoring this difference affects inventory decisions, such as safety and cycle inventory levels. Therefore, it is imperative for managers to revise their status quo strategies, such as on inventory procurement, assortment planning, and product display, when integrating m-commerce with e-commerce.
Coordinated Operational Optimization Approach for PV Inverters and BESSs to Minimize the Energy Loss of Distribution Networks

The article presents a coordinated operational optimization approach for PV inverters and battery energy storage systems (BESSs) to minimize the energy loss in distribution networks with time-varying load demand and PV generation. PV inverters are modeled to inject available PV generation into a network during PV generation hours and to provide VAr compensation during rest of the time. BESSs are modeled to store surplus PV power during high penetration of PV generation and to discharge stored energy during no/low PV generation hours. An optimization problem is formulated to determine the optimal VAr compensation setpoints for PV inverters and optimal charge/discharge schedule for the BESSs. The maximization of PV hosting capacity and the minimization of energy loss are the objective functions for the first and second stages, respectively. The limits on bus voltage magnitude, line flow, state-of-charge (SOC) of BESSs, charging and discharging of BESSs, PV inverter capacity, etc., are considered to be the operational constraints. The CONOPT solver of general algebraic modeling system software is used for solving the optimization problem. The contribution of the proposed approach is to show that significant energy loss reduction can be obtained with the optimal time-varying setpoints of PV inverters and BESSs.
Fault diagnosability of regular graphs

An interconnection network’s diagnosability is an important measure of its selfdiagnostic capability. In 2012, Peng et al. proposed a measure for fault diagnosis of the network, namely, the h-good-neighbor conditional diagnosability, which requires that every fault-free node has at least h fault-free neighbors. There are two well-known diagnostic models, PMC model and MM* model. The h-goodneighbor diagnosability under the PMC (resp. MM*) model of a graph G, denoted by tPMC h (G) (resp. t MM∗ h (G)), is the maximum value of t such that G is h-good-neighbor t-diagnosable under the PMC (resp. MM*) model. In this paper, we study the 2-good-neighbor diagnosability of some general k-regular kconnected graphs G under the PMC model and the MM* model. The main result tPMC 2 (G) = t MM∗ 2 (G) = g(k − 1)− 1 with some acceptable conditions is obtained, where g is the girth of G. Furthermore, the following new results under the two models are obtained: tPMC 2 (HSn) = t MM∗ 2 (HSn) = 4n− 5 for the hierarchical star network HSn, t PMC 2 (S 2 n) = t MM∗ 2 (S 2 n) = 6n− 13 for the split-star networks S2 n and tPMC 2 (Γn(∆)) = t MM∗ 2 (Γn(∆)) = 6n − 16 for the Cayley graph generated by the 2-tree Γn(∆).
A Modified Radon Fourier Transform for GNSS-Based Bistatic Radar Target Detection

The Global Navigation Satellite System (GNSS)-based passive bistatic radar (PBR) which uses the GNSS signal as the illuminators of opportunity is studied for moving target detection (MTD). GNSS-based PBR has many advantages due to the removal of the transmitting device; however, its fundamental limitation is the low power density of the GNSS signal. Therefore, the integration time should be sufficiently long to obtain a promising maximum detectable range. On the other hand, the integration time is limited by the range migration and Doppler migration of the echo caused by target motion. In this letter, a novel MTD algorithm is proposed for the GNSS-based PBR, by employing a modified radon Fourier transform (MRFT) to achieve the required long-time integration for moving targets. The MRFT integrates the echo energy via joint searching of range, Doppler, and Doppler rate of the target, which can handle not only the range migration but also the Doppler migration problems, and significantly improves the signal-to-noise ratio (SNR) of the echo signal. An experiment using the GPS L5 signal as the illumination source is conducted and a moving car is successfully detected by the proposed algorithm, although significant range migration and Doppler migration are present due to variation of its speed.
Path and function synthesis of multi-bar mechanisms using beetle antennae search algorithm

Beetle antennae search algorithm (BAS) is based on the searching behavior of longhorn beetles. This newly proposed metaheuristic algorithm is used in the path and function synthesis of multi-bar mechanism. The optimization results are compared with that of other metaheuristic algorithms like genetic algorithm (GA), particle swarm optimization (PSO) and differential evolution (DE) et al. While BAS uses only one group of initial parameters to search the best result, the convergence and efficiency are tested with eight case studies results. Newly added parameter q increases the possibility to find better results during iterations and deals with a higher number of independent parameters efficiently. Revised BAS exhibits good performance both in path synthesis of four-bar mechanism with or without prescribed timing, while optimized parameters increases from 6 to 34, and extends to path and function combined synthesis of Stephenson III six-bar double dwell mechanism with 14 parameters.
Joint-Elicitation of Elasticity of Intertemporal Substitution, Risk and Time Preferences

The elicitation of the elasticity of intertemporal substitution (EIS), discount factor and risk attitude parameters in dynamic models is of central importance to economics, finance and public policy. This paper suggests an alternative method to jointly elicit and estimate these three parameters using experimental data. We employ a new model based on dynamic quantile preferences, where individuals maximize the stream of future ‐quantile utilities, for . These preferences are simple, dynamically consistent and monotonic. In the quantile model, the risk attitude is captured by the quantile of the payoff distribution, while the EIS and the discount factor are related to the utility function describing individual's intertemporal behaviour, hence allowing for complete separability between risk, EIS and discount factor. The estimation of the parameters of interest uses a structural maximum likelihood method. Individual's risk aversion is estimated below the median. The discount factor is marginally smaller than estimates reported in the literature, and the EIS is slightly larger than one, which suggests that utility over time is concave. The estimates for the elasticity contrast with those reported by the existing studies using observational disaggregated data, which in general find an elasticity smaller than one.
Gait Kinematics Index, Global Symmetry Index and Gait Deviations Profile: Concept of a new comprehensive method of gait pathology evaluation.

PURPOSE The objective of the work was to define a new comprehensive method of evaluating gait pathology (Gait Kinematics Index, Global Symmetry Index and Gait Deviations Profile). METHODS The article presents in detail a mathematical algorithm of a new comprehensive method of evaluating gait pathology. Input data for the algorithm are the kinematic parameters of gait. The method is based on the determination of the following parameters: standardized angular variables (Wji), kinematic indicators of gait (KIj), gait cycle indicators (GCIi), Gait Kinematic Index (GKI), Gait Deviations Profile (GDP, GDPj), Global Symmetry Index (GSI) and Symmetry Indices (SIj) for kinematic gait values. The algorithm is based on the determination of the difference between results obtained in relation to the kinematics of movement of a given patient and the average value obtained in relation to the standard in each percentage of a gait cycle. The proposed method was tested using results obtained for 59 healthy persons and one patient with locomotor function disorder. RESULTS The GKI values for the reference group amounted to 0.89 ± 0.23. Information which can be obtained using the proposed gait assessment method was presented using an example of a patient with the disorder of locomotor functions. Areas of gait deviations, which were identified on the basis of the determined indicators, were presented in a graphic form using GDP. CONCLUSIONS The new gait assessment method makes it possible to identify gait using a single numerical value, evaluate movements in individual joints and in subsequent moments as well as to assess the symmetry of gait.
Improvement in the viability of cryopreserved cells by microencapsulation

The purpose of this study is to clarify whether microencapsulated cells have an advantage over suspended cells in cryopreservation. Rat pheochromocytoma (CP 12) cells were selected for test biological cell and microencapusulated in alginate-polylysine-alginate membranes. Microencapsulated PC 12 cells were frozen with differential scanning calorymetry (DSC) at a cooling rate of 0.5 to 10°C/min. Their latent heat were measured in freezing process over the temperature range 4 to -80°C. The post-thaw viability was evaluated with dopamine release and trypan blue exclusion assay. As a result, latent heat of encapsulated cells were lower than that of suspended cells at a cooling rate of 0.5 and 1°C/min. This is because extra-capusle was frozen and intra-capsule unfrozen, as ice crystals forms in extra-capsule space. The post-thaw vability of microencapsulated PC 12 cells was improved at 0.5 and 1°C/min compared with that of suspended cells. Therefore, in microencapsulated PC 12 cells, acievement of intra-capsules unfrozen condition during freezing leads to reducing the solution effect and improving the post-thaw viability.
Predicting Covid-19 Cases using CNN Model

: The prediction of COVD-19 confirmed cases is a complex time-series problem. In the literature, Long Short Time Memory (LSTM) has proven its efficiency to resolve issues related to the time series problems. However, Convolution neural network (CNN) did not been widely used in this aim and is considered as more suitable for imaging processing. Therefore, in this paper, we use it to predict COVID-19 cases and compared it with LSTM in the context of Morocco during the period of confinement. The obtained results which we present and discuss in this article are very promising.
Phylogenetic and evolutionary analyses of the VP4 gene of P[9] rotaviruses

Objectives: Rotavirus is one of the major causes of gastroenteritis in children under 5 years of age and is responsible for over 200,000 deaths annually. Rotavirus can evolve by reassortment, in which gene segments are exchanged between strains of different origins. Rotavirus strains with the P[9] genotype is an example of reassortment, in which the P[9] genotype is from feline species. A number of outbreaks associated with P[9] strains have been documented in several countries. However, details regarding the epidemiological relationships between the strains remains largely unknown. Therefore, in the present study, genetic characterization and evolutionary analyses were performed to gain insight into P[9] strains circulating in different parts of the world. Results: The VP4 gene of the P[9] strains could be divided into six lineages, and P[9] strains characterized in this study share a common ancestor that circulated in circa 1864. In each lineage, the strains were not only from different countries, but also from different continents. These findings suggest that none of the lineages has a specific region of distribution, and although humans have had interactions with cats for thousands of years, the common ancestor of the VP4 gene of the current P[9] strains is relatively recent.
Máxima Información, Mínima Molestia (MIMO): Reducir cuestionarios para cuidar de las personas participantes en psicología del deporte

Contestar a un gran número de ítems puede suponer una gran carga para las personas participantes, lo cual puede empeorar la calidad de los datos recogidos. Por este motivo, el propósito de nuestro estudio es presentar el método de Máxima Información, Mínima Molestia (MIMO) para el desarrollo de versiones cortas en psicología del deporte. Nuestro protocolo propone cuatro fases para preparar la versión corta de un cuestionario ya existente. Concretamente, proponemos (a) realizar una selección inicial de ítems en base a criterios teóricos, psicométricos y de comprensión (Fase I); (b) refinar la versión corta gracias a las opiniones de un panel de personas expertas (Fase II); (c) evaluar la comprensión de los ítems por parte de la población diana (Fase III); y (d) evaluar la estructura factorial, fiabilidad y validez de relación con otras variables (Fase IV). Para cada fase, aportamos justificación, explicamos su desarrollo, las personas involucradas, y ofrecemos un ejemplo real de cómo podría aplicarse. En esencia, el método MIMO permite desarrollar versiones cortas que cuiden de las personas participantes, evalúen los aspectos clave de los constructos, conserven las propiedades psicométricas e incrementen la calidad de los datos recogidos.
Development, Practice Patterns, and Early Clinical Outcomes of a Multidisciplinary Liver Cancer Clinic

Multidisciplinary care has been associated with improved survival in patients with primary liver cancers. We report the practice patterns and real world clinical outcomes for patients presenting to the Johns Hopkins Hospital (JHH) multidisciplinary liver clinic (MDLC). We analyzed hepatocellular carcinoma (HCC, n = 100) and biliary tract cancer (BTC, n = 76) patients evaluated at the JHH MDLC in 2019. We describe the conduct of the clinic, consensus decisions for patient management based on stage categories, and describe treatment approaches and outcomes based on these categories. We describe subclassification of BCLC stage C into 2 parts, and subclassification of cholangiocarcinoma into 4 stages. A treatment consensus was finalized on the day of MDLC for the majority of patients (89% in HCC, 87% in BTC), with high adherence to MDLC recommendations (91% in HCC, 100% in BTC). Among patients presenting for a second opinion regarding management, 28% of HCC and 31% of BTC patients were given new therapeutic recommendations. For HCC patients, at a median follow up of 11.7 months (0.7-19.4 months), median OS was not reached in BCLC A and B patients. In BTC patients, at a median follow up of 14.2 months (0.9-21.1 months) the median OS was not reached in patients with resectable or borderline resectable disease, and was 11.9 months in patients with unresectable or metastatic disease. Coordinated expert multidisciplinary care is feasible for primary liver cancers with high adherence to recommendations and a change in treatment for a sizeable minority of patients.
Biomechanical comparison between the custom-made mandibular condyle prosthesis and total temporomandibular joint prosthesis in finite element analysis.

PURPOSE The purpose of this study was to compare the biomechanical behavior of the custom-made mandibular condyle prosthesis and total TMJ prosthesis. METHODS Three models of one beagle dog, the condyle prosthesis (Model 1, replacing the right condyle only), the TMJ prosthesis (model 2, replacing the whole right TMJ) and the intact TMJ (model 3) were established, and the mechanical responses under muscle forces loading were analyzed using finite element method. RESULTS Models 1 and 3 had the similar stress distribution on the right disc, which suggested that the condyle prosthesis did not change the disc stress so much when the muscle forces were applied. The stress of the right TMJ prosthesis in Model 2 was larger than both Models 1 and 3, and the stress of the contralateral TMJ reduced by 12% in Model 2. The anterior border of the condyle seemed to be a stress concentration region, not only for the intact condyle, but also for the condyle prosthesis and the total TMJ prosthesis. CONCLUSIONS The total TMJ prosthesis changed the biomechanical balance of the bilateral TMJ. When the condyle prosthesis iss applied, the custom-made profile is recommended.
