Authors: Sh Alshareef T 
Published: August 2020

Abstract
Waveform flow of non-Newtonian fluid through a porous medium of the non-symmetric sloping canal under the effect of rotation and magnetic force, which has applied by the inclined way, have studied analytically and computed numerically. Slip boundary conditions on velocity distribution and stream function are used. We have taken the influence of heat and mass transfer in the consideration in our study. We carried out the mathematical model by using the presumption of low Reynolds number and small wave number. The resulting equations of motion, which are representing by the velocity profile and stream function distribution, solved by using the method of a domain decomposition analysis and we obtained the exact solutions of velocity, temperature, and concentration. The expressions of velocity, temperature, and concentration of the particles of the fluid have obtained and examined graphically by utilizing the soft wave of the Mathematica program. The efforts of various variables on mathematical modeling of motion and energy are discussed in detail. We found that.

Authors: Youssef I. K. , Ali Adel Rashed A. 
Published: August 2020

AbstractThe Caputo definition of fractional derivatives introduces solution to the difficulties appears in the numerical treatment of differential equations due its consistency in differentiating constant functions. In the same time the memory and hereditary behaviors of the time fractional order derivatives (TFODE) still common in all definitions of fractional derivatives. The use of properties of companion matrices appears in reformulating multilevel schemes as generalized two level schemes is employed with the Gerschgorin disc theorems to prove stability condition. Caputo fractional derivatives with finite difference representations is considered. Moreover the effect of using the inverse operator which transmit the memory and hereditary effects to other terms is examined. The theoretical results is applied to a numerical example. The calculated solution has a good agreement with the exact solution.

Published: August 2020

Abstract
The two-dimensional integro-differential partial equations is one of the so difficult problems to be solved analytically and/or approximately, and therefore, a method that is efficient for solving such type of problems seems to be necessary. Therefore, in this paper, the iteration methods, which is so called the variational iteration method have been used to provide a solution to such type of problems approximately, in which the obtained results are very accurate in comparison with the exact solution for certain well selected examples which are constructed so that the exact solution exist. Main results of this work is to derive first the variational iteration formula and then analyzing analytically the error term and prove its convergence to zero as the number of iteration increases.

Negative impacts of plant diversity loss on carbon sequestration exacerbate over time in grasslands
Authors: Wang Chao , Tang Yujia , Li Xiaona , Zhang Weiwei , Zhao Chunqiao , Li Cui 
Published: August 2020

Abstract
Positive relationships between plant species diversity and carbon attributes have been observed in grasslands, but synthesis studies of how plant diversity affects the carbon balance of grasslands and how the response ratio changes over time both remain limited. By conducting a global meta-analysis with 811 paired observations of plant mixtures and monocultures from 83 studies in natural and manipulated grasslands, we investigated the impacts of plant diversity on six carbon attributes, its interaction with experimental duration, and the changes in carbon balance under different plant diversity loss scenarios in the future. We found that the aboveground biomass (AGB), belowground biomass (BGB), total biomass (TB), soil organic carbon (SOC), soil respiration (Rs), and heterotrophic respiration (Rh) significantly increased in the plant mixtures, and the response ratio for all carbon attributes increased logarithmically with species richness. We also found that the response ratio for all carbon attributes except Rs increased linearly with experimental duration. The increase in response ratio of AGB, BGB, TB, and SOC with species richness was more pronounced with the long-term experimental duration. Importantly, our results showed that the declines in carbon sequestration will be exacerbated by different plant diversity loss scenarios in the future. Our meta-analysis revealed that plant diversity loss has ubiquitous negative impacts on multiple carbon attributes in grasslands, underlined the interactive effects of plant diversity loss and experimental duration on carbon attributes, and suggested that the reduction of carbon storage in grasslands following biodiversity loss will be greater in the future.
Stochastic fluctuations as a driving force to dissipative non-equilibrium states
Authors: Chanu Athokpam Langlen , Bhadana Jyoti , Brojen Singh R K 
Published: August 2020

Abstract
Most natural complex systems exhibit fluctuations-driven processes, which work at far from equilibrium states, and are generally dissipative processes, for instance living cells. We studied this phenomenon within the stochastic framework by taking a set of nonequilibrium, bimolecular, autocatalytic reactions, originally proposed by Nicolis (1972). We also extended this model to incorporate the concept of time delay. Firstly, for both non-delay and delay cases, we calculated the exact non-stationary probability distribution solutions of the corresponding Master equations, which are found to deviate from the Maxwell–Boltzmann distribution. The analytically calculated probability distribution P of an autocatalyst X in the chemically reacting model system is found to follow some universal class of probability distributions at different situations. At the thermodynamic limit with a large population, P obeys Normal distribution. Again, we showed that one of the causes of this peculiar behaviour is the fluctuations in the reacting system. The analytical result of the Fano factor F in the non-delay case predicted a noise-enhanced process for our dynamical stochastic system which could probably drive the system far from equilibrium. For the delay case, the analytically calculated F was found to depend on the time delay function, which predicts that time delay could play an important role in regulating the system dynamics. These analytical predictions were then verified using numerical experiments with the stochastic simulation algorithm (SSA) and delay stochastic simulation algorithm (DSSA). Indeed, numerical results from SSA and DSSA confirmed noise-enhanced processes which are far from equilibrium and dissipative in nature.
Multiclass classification of patients during different stages of Alzheimer’s disease using fMRI time-series

Published: August 2020

Abstract
Alzheimer’s Disease (AD) begins several years before the symptoms develop. It starts with Mild Cognitive Impairment (MCI) which can be separated into Early MCI and Late MCI (EMCI and LMCI). Functional connectivity analysis and classification are done among the different stages of illness with Functional Magnetic Resonance Imaging (fMRI). In this study, in addition to the four stages including healthy, EMCI, LMCI, and AD, the patients have been tracked for a year. Indeed, the classification has been done among 7 groups to analyze the functional connectivity changes in one year in different stages. After generating the functional connectivity graphs for eliminating the weak links, three different sparsification methods were used. In addition to simple thresholding, spectral sparsification based on effective resistance and sparse autoencoder were performed in order to analyze the effect of sparsification routine on classification results. Also, instead of extracting common features, the correlation matrices were reshaped to a correlation vector and used as a feature vector to enter the classifier. Since the correlation matrix is symmetric, in another analysis half of the feature vector was used, moreover, the Genetic Algorithm (GA) also utilized for feature vector dimension reduction. The non-linear SVM classifier with a polynomial kernel applied. The results showed that the autoencoder sparsification method had the greatest discrimination power with the accuracy of 98.35% for classification when the feature vector was the full correlation matrix.
Time limit for using the semi-infinite heat transfer solutions: a novel approach
Authors: Yadav Mahesh Kumar , Yadav Vinod 
Published: August 2020

Abstract
In the present study, authors are conceptually showing that the classically considered time limit to use the semi-infinite approximate solutions is highly conservative, particularly at the internal location(s) inside the finite heat conduction medium. Accordingly, a new length scale, which accounts the heat propagation from the far-field boundary condition as well, is proposed to ascertain the prolonged time limit. The proposed time limit is obtained by comparing the temperature distribution in a finite heat conduction problem with its equivalent semi-infinite model. Overall, three standard one-dimensional heat conduction problems are analysed and the proposed time limit is found to be valid in all three problems. The new time limit will certainly boost the utility of the semi-infinite solutions and rejuvenate the interest of the scientific community in such solutions.
The Kids Aren’t All Right: Historians and the Problem of Childhood
Authors: Maza Sarah 
Published: August 2020

Abstract
In a complement to the 2020 AHR Roundtable “Chronological Age: A Useful Category of Historical Analysis” (125, no. 2), this AHR Exchange focuses on the history of children and childhood. Sarah Maza presents a critical review essay, highlighting the limiting factors in the expanding field of childhood studies. Children, she observes, produce few sources of their own voices, have limited agency, and as individuals and as a group soon outgrow their subaltern status—they grow up. Robin P. Chapdelaine, Nara Milanich, Steven Mintz, Ishita Pande, and Bengt Sandin—historians representing diverse geographical, theoretical, and methodological perspectives on the history of children and childhood—react to Maza’s observations by bringing up important methodological questions about subjecthood, agency, and modernity. Maza’s rejoinder reflects on these questions and on the possibility of age-based historical agency.

Published: August 2020

Abstract
Objectives: Aberrant expression of neuroendocrine markers has been reported in angiosarcomas and can occasionally result in diagnostic confusion. The aim of this study was to evaluate the expression of insulinoma-associated protein 1 (INSM1), a marker for neuroendocrine differentiation, in angiosarcomas as well as other sarcomas.
Methods: Tissue microarrays, including angiosarcoma, Ewing sarcoma, desmoplastic small round cell tumor (DSRCT), clear cell sarcoma, synovial sarcoma, leiomyosarcoma, alveolar soft part sarcoma, epithelioid sarcoma, and undifferentiated pleomorphic sarcoma, were evaluated for expression of INSM1. The extent of immunoreactivity was graded according to the percentage of positive tumor cell nuclei (0, no staining; 1+, &lt;5%; 2+, 5%-25%; 3+, 26%-50%; 4+, 51%-75%; and 5+, 76%-100%), and the intensity of staining was graded as weak, moderate, or strong.
Results: INSM1 expression was found in a subset of angiosarcomas (n = 24/94, 26%; majority 5+, weak to moderate), as well as DSRCTs (n = 7/62, 11%; 2+, weak to strong) and rarely synovial sarcomas (n = 3/76, 4%; 2+, moderate to strong). No INSM1 expression was detected in the other sarcomas.
Conclusions: Aberrant expression of INSM1 can be seen in a subset of angiosarcomas often with diffuse labeling. Other sarcomas that can rarely demonstrate small cell morphology and focal INSM1 expression include DSRCT and synovial sarcoma.

Authors: Jaberizadeh Leva , Peterson Jasmine , Thrall Stephanie 
Published: August 2020

Abstract

Purpose
To evaluate the impact of hiring nonclinical support staff on pharmacist productivity and diabetes control outcomes in internal medicine clinics of an integrated healthcare system.

Methods
A retrospective, longitudinal cohort study was conducted. Patients were included if they were contacted by telephone for a diabetes consultation with a clinical pharmacist from July 1, 2015, through June 30, 2017. Nonclinical support staff were hired in July 2016 to schedule patient appointments with the clinical pharmacists. The primary outcome was the average rate of completed telephone encounters per month before and after hiring of nonclinical support staff. The secondary outcome was the mean change in glycated hemoglobin (HbA1c) level in patients who had a laboratory assay completed within 90 days of clinical pharmacist outreach. The tertiary outcome was the call completion rate for scheduled appointments vs unscheduled calls.

Results
In total, 6,709 patients were included; their average age was 55 years. After the intervention, the mean (SD) rate of completed telephone encounters increased from 61% (3.8%) to 77% (3.5%) (P &lt; 0.001). Small improvements were noted in glycemic control, as measured by the mean (SD) percentage of patients with an HbA1c concentration of &lt;8%, which increased from 31% (5.2%) to 42% (3.0%) (P &lt; 0.001), and the mean (SD) change in average HbA1c concentration, which increased from 8.9% (0.2%) to 8.5% (0.1%) (P &lt; 0.001). Throughout the study, scheduled calls were more likely to be completed than unscheduled calls (mean [SD] completion rate, 66% [9.0%] vs 74% [6.0%]; P &lt; 0.001).

Conclusion
Hiring nonclinical support staff led to greater efficiency among the clinical pharmacist team, yielding a higher volume of telephone interactions, a modest overall decrease in HbA1c values, and an increased likelihood of reaching patients by phone.
Origin-independent analysis links SARS-CoV-2 local genomes with COVID-19 incidence and mortality
Authors: Yang Wenzhong , Jin Guangxu 
Published: August 2020

Abstract
There is an urgent public health need to better understand Severe Acute Respiratory Syndrome (SARS)-CoV-2/COVID-19, particularly how sequences of the viruses could lead to diverse incidence and mortality of COVID-19 in different countries. However, because of its unknown ancestors and hosts, elucidating the genetic variations of the novel coronavirus, SARS-CoV-2, has been difficult. Without needing to know ancestors, we identified an uneven distribution of local genome similarities among the viruses categorized by geographic regions, and it was strongly correlated with incidence and mortality. To ensure unbiased and origin-independent analyses, we used a pairwise comparison of local genome sequences of virus genomes by Basic Local Alignment Search Tool (BLAST). We found a strong statistical correlation between dominance of the SARS-CoV-2 in distributions of uneven similarities and the incidence and mortality of illness. Genomic annotation of the BLAST hits also showed that viruses from geographic regions with severe infections tended to have more dynamic genomic regions in the SARS-CoV-2 receptor-binding domain (RBD) and receptor-binding motif (RBM) of the spike protein (S protein). Dynamic domains in the S protein were also confirmed by a canyon region of mismatches coincident with RBM and RBD, without hits of alignments of 100% matching. Thus, our origin-independent analysis suggests that the dynamic and unstable SARS-CoV-2-RBD could be the main reason for diverse incidence and mortality of COVID-19 infection.
