Abstract
An interactive artificial ecological optimization algorithm (SIAEO) based on environmental stimulus and competition mechanism was devised to find the solution of complex calculation and be apt to get bogged down in local optimum in virtue of the sequential execution of consumption and decomposition stages in artificial ecological optimization algorithm. Firstly, the environmental stimulus defined by population diversity makes the population interactively execute the consumption operator and decomposition operator to abate the inhomogeneity of the algorithm. Secondly, the three different types of predation modes in the consumption stage were regarded as three different tasks, and the task execution mode was determined by the maximum cumulative success rate of each individual task execution. Furthermore, the biological competition operator is recommended to modify the regeneration strategy, so that the SIAEO algorithm can give consideration to the exploitation in the exploration stage, break the equal probability execution mode of the AEO, and promote the competition among operators. Finally, the stochastic mean suppression alternation exploitation problem is introduced in the later exploitation process of the algorithm, which can tremendously heighten the SIAEO algorithm to run away the local optimum. A comprehensive comparison between SIAEO and other improved algorithms is performed on the challenging CEC2017 and the latest CEC2019 test set. The optimization results state clearly that the SIAEO algorithm possesses excellent property in search efficiency, convergence accuracy and avoiding local optimization for both high and fixed dimensional questions. In the meantime, the SIAEO algorithm is utilized to resolve the four engineering majorization problems and high-dimensional K-means clustering problem, and the comparison results verify that the SIAEO algorithm is provided with good practical performance.

Abstract
In this model, we consider the customers arrive according to Markovian Arrival Process (MAP) and their three fluctuating modes of service and repair process of both servers are based on phase-type (PH) distributions. While the main server-1 is offering any one of the modes of service who may affect by breakdown immediately go for phase-type repair process at that moment the standby server will interrupt the main server-1 and carry over the service process up to the phase-type repair completion of main server-1. Likewise, the main server-2 also caused by breakdown while offering any one of the modes of service to customers but the main server-2 has a capacity to provide service at the slower rate for the interrupted customer only before move to the phase-type repair process for rejuvenation due to the concept of working breakdown. At every service completion epoch, the main server-1 has an option to move forward to vacation or else remain in the system to offer service to next customer who is next in the queue. If both the server’s are unavailable in the system, the waiting customers in the queueing line may renege from the system because of impatient behaviour. Using matrix analytic method, we examine the steady-state probability vector, busy period and waiting time distribution. Furthermore, we illustrated some of the numerical and graphical representations of the proposed model.
Mathematical Model for the Quantification of Pulmonary and Intrapulmonary Arteriovenous Anastomoses Blood Flow
Authors: Vanni Rosalba 
Published: January 2023

Abstract

Background: Accurately quantifying blood flow through a shunt vessel is vitally important, because
shunt prevents gas exchange and can provide a pathway for emboli that bypass the pulmonary
microcirculation. Some current techniques allow an approximate estimate of the pulmonary shunt
and present technical and evaluative difficulties that can compromise the result.
Objectives: To develop a mathematical model, based on important chemical-physical laws, for the
precise calculation of pulmonary blood flow (Qp), intrapulmonary arteriovenous anastomoses blood
flow (QIPAVA) and then validate it.
Methods: Some experimental data, obtained from healthy subjects, were input into the model.
Results: Qp and QIPAVA were precisely calculated at rest and at moderate (50% of VO2max) and heavy exercise (90% of VO2max) in both normoxia (FIO2 = 0.2093) and acute hypoxia (FIO2 = 0.125).
In normoxia under heavy exercise, Qp decreased slightly (97.56% of Qt), and QIPAVA represented
2.44% of Qt.
Instead, in hypoxia at heavy exercise, Qp decreased significantly (85.25% of Qt), and QIPAVA
increased significantly (14.75% of Qt).
It was possible to demonstrate a negative contribution of QIPAVA directly to gas exchange efficiency
and identify incorrect Qt measurements.
Conclusions: This model is precise because composed of equations which describe the real
representation of gas exchange and therefore of universal application.
Qp differs significantly from Qt under some physiological conditions already in healthy subjects.
The use of this model will allow research a general advance in the understanding of this critical
biological function and in clinical practice a precise and early detection of the pathology.

Abstract
Purpose. The commitment of multidisciplinary teams in antimicrobial stewardship programs (ASPs) is often inadequately considered, especially in surgical wards. We wanted to evaluate clinical, microbiological, and pharmacological outcomes before and after the implementation of an ASP in the Vascular Surgery ward of Fondazione IRCCS Policlinico San Matteo, a tertiary care hospital in Pavia, Italy.
Methods. This was a quasi-experimental quality-improvement study. The antimicrobial stewardship activity was conducted twice a week for 12 months and consisted of both prospective audit and feedback of all the ongoing antimicrobial prescriptions by the infectious diseases’ consultants and educational meetings for the healthcare workers of the Vascular Surgery ward. For comparison between the study periods, Student t test (Mann-Whitney test for skewed distributions) was used for quantitative variables (ANOVA or Kruskall-Wallis for >2 groups respectively), and Pearson’s chi-squared test (Fisher exact test where appropriate) for categorical variables. 2-tailed tests were used. P-value significance cut-off was 0.05.
Results. During the 12-month intervention period, among a total number of 689 patients, 186 prescriptions were revised, mostly leading to de-escalating an ongoing antimicrobial therapy (39, 20.97%). A statistically significant reduction in isolates of carbapenem-resistant Pseudomonas aeruginosa (p-value 0.003) and the absence of Clostridioides difficileinfections were reported. No statistically significant changes were observed in terms of length of stay and all-cause in-hospital mortality. A significant decrease in the administration of carbapenems (p-value 0.01), daptomycin (p-value <0.01) and linezolid (p-value 0.43) was registered. A significant reduction in antimicrobial costs was also observed.
Conclusions. The implementation of a 12-month ASP brought significant clinical and economic results, highlighting the benefits of a multidisciplinary teamwork.

Abstract
The aim of this research work is to simultaneously evaluate the effects of inhomogeneous plastic strain-induced and anisotropy on frictional behavior. The studied material is the cold-rolled steel grade DC06EK intended for sheet metal forming. To achieve this work, stretched and unstretched DC06EK strips following different rolling directions (0°, 45° and 90°) with different levels of equivalent plastic strain were used in microscratch tests. The findings show that the calculated coefficient of friction (COF) decreases as a function of the equivalent plastic strain for different rolling directions. The COF have a clear trend lines of regression except in the case for 45°. Trend lines of the COF following 0° and 90° converge to very closely values, since the effect of anisotropy disappears with the increase in the level of plastic strain.
Epigenomics in stress tolerance of plants under the climate change
Authors: Kumar Mithlesh , Rani Kirti , Goswami Parth 
Published: January 2023

Abstract
During development and environmental stresses, plants experience genome-wide epigenetic alterations that are typically associated with differentiation in transcriptional gene expression.
An epigenome is the aggregate of a cell's biochemical modifications in its nuclear DNA, post-translational changes in histones, and differences in non-coding RNAs' biogenesis. Differences in gene expression that take place without any change in the underlying nucleotide sequence are frequently caused by these changes. Chromatin remodelling that can epigenetically dictate particular transcriptional outputs and change the function/activity of the genome include post-transcriptional histone modifications, variations in histone proteins, DNA methylation, and activity of non-coding RNA. Epigenetic marks have a significant impact on how plants respond to environmental challenges, and recent developments in the field of major crop "-omics" have made it easier to identify these marks. The phenotypic plasticity of the organism is impacted by the epigenomic alterations, which are dynamic in response to any endogenous and/or external stimuli. After the stress is withdrawn, both changes in gene expression and epigenetic alterations may quickly return to their pre-stress states. Few epigenetic alterations, which have been related to acclimatisation, adaptation, and the evolutionary process, might be retained, though. For better use of genetic resources, epigenome engineering may be used to improve plants' ability to withstand stress. In this chapter, we have outlined recent epigenetic studies that may be crucial for enhancing crop resilience and adaptation to environmental changes, ultimately resulting in the development of stable climate-smart crops.

Abstract
A digital business model is a way of generating value based on the creation of client advantages using digital technology. The goal of the digital solution is to provide a significant advantage that customers are willing to pay for. For businesses facing digital disruption and digitization, developing digital business models is a crucial responsibility. A global platform for communication, the Internet is rapidly being utilized as a cutting-edge tool for product and service marketing. A competitive threat to conventional retail establishments, online digital market platforms have many benefits over traditional shopping methods. Consumers are quickly embracing internet shopping around the world, and Ethiopia is no exception. Online digital market platform marketers and retailers can further expand their marketing strategies to draw in and keep customers in order to gain a competitive edge globally if they are aware of the elements influencing consumers' purchasing intentions. Due to the scarcity of published research on the variables influencing Ethiopian consumers' intention to purchase online, there is a conceptual gap in the literature on online digital marketing. By identifying the crucial variables impacting Ethiopian consumers' desire to purchase on online digital market platforms, this study aims to close this conceptual gap in the context of online market platform purchasing. The information was gathered from 100 Ethiopian, Addis Ababa University, final year engineering students using a self-administered 5-point Likert scale questionnaire. The partial least square structural model (PLS-SEM) technique was used to examine the data. The results of this study highlighted five crucial decision-making elements that have an impact on Ethiopian consumers' intention to buy on online digital market platforms including Website Design, Perceived Usefulness, Perceived Ease of Use, Trust, and Subjective Norm. With the use of this information, manufacturers, online marketers, and retailers can create effective market strategies, enhance technology, and make smart marketing choices that will help them gain global competitive advantage.
A Randomized Algorithm for Finding Local Maximum Cuts
Authors: Gao Lunshan 
Published: January 2023

Abstract
This paper describes a new randomized algorithm for calculating local maximum cuts of the maximum cut problems in graph theory. The new algorithm transforms the maximum cut problem into a new form by using fuzzy logic technique. The transformation enables the algorithm to use the first-order derivative method to find optimal values for discrete non-linear optimization problems. This paper proves that the solution of the new algorithm satisfies the ϵ−δ condition. The algorithm converts decimal solution points to integer solution points by using the defuzzification technique. This paper also proves that the defuzzification maintains the local maximum value. The new algorithm is compared with IBM ILOG CPLEX. The numerical experiments indicate that the performance of the new algorithm is better than that of IBM ILOG CPLEX for finding local maximum cuts.

Published: January 2023

Abstract
Real parameter single objective optimization has been studied for decades to find the best decision vector to minimize (or maximize) an objective multi-dimension function. In recent, a new setting is proposed and applied in this field based on the consideration that solving difficulty scales exponentially with the increase of dimensionality. Under the new setting, Differential Evolution (DE) still outstands in performance as before. Meanwhile, a new type of population-based metaheuristic - Gaining-Sharing Knowledge based algorithm (GSK) becomes a dark horse. Furthermore, ensemble of the above two types of algorithm - APGSK-IMODE - is proposed in literature. In this paper, we change the scheme for executing communication between the two constituent algorithms - APGSK and IMODE, and propose APGSK-IMODE-II. In our experiment, our algorithm is compared with state-of-the-art algorithms. Experimental results show that our APGSK-IMODE-II is very competitive.

Published: January 2023

Abstract
A spectrum-sliced (SS) Wavelength division multiplexing (WDM) based Free-space optical (FSO) communication system at a data rate of 2.5 Gbps per optical carrier is proposed in this research article. Utilizing the broadening of the spectrum by means of supercontinuum generation in a highly non linear Fiber (HNLF), an SS-WDM based FSO system is designed. The narrow spectrum of laser light source is broadened by means of self phase modulation (SPM). The proposed work reveals that the DQPSK based SS-WDM FSO system has higher performance compared to intensity modulation formats as well as other differential phase modulation formats. Considering various values of FSO link distances, antenna diameters of transmitter and receiver, beam divergence and thus, determining the values of performance metrics such as Q-factor and bit error rate (BER), differential quadrature phase shift keying (DQPSK) based SS-WDM FSO system is simulated. The same process is repeated for dual channel FSO system for DPSK and DQPSK.

Abstract
Subcortical brain structures are the hubs for various psycho-behavioral functions. There is no mega-analysis to simultaneously investigate subcortical volumetric alterations in schizophrenia, bipolar disorder, major depressive disorder, and autism spectrum disorder. Nor are there any neuroimaging data-driven clinical criteria overcoming limitations of the current diagnostic system, which would reflect cognitive/social functioning. We conducted a large-scale multisite study of subcortical volumetric and lateralization alterations in these disorders using T1-weighted images of 5,604 subjects (3,078 controls and 2,526 patients). We found schizophrenia-specific and cross-disorder shared alterations. Moreover, we clustered the 5,604 subjects based on subcortical volumes, and explored whether data-driven clustering results can explain cognitive/social functioning in the subcohorts. We showed a four-biotype classification, namely extremely and moderately smaller limbic regions, larger basal ganglia, and normal volumes, for predicting cognitive/social functioning. Our results will contribute to the future creation of novel biological data-driven psychiatry diagnostic criteria, expected to support appropriate treatment selection.

Abstract
Background:
The classification of the central nervous system (CNS) tumors has changed greatly. The Central Brain Tumor Registry of the United States (CBTRUS) and other institutions have conducted analyses on the new cases of primary CNS tumors. However, there are limited studies analyzing the incidence rate and characteristics of CNS tumors reported in China. To better understand the CNS tumors in China, we summarized the case details of all CNS primary tumors diagnosed pathologically in a single center from 2003 to 2019.
Methods:
All patients with CNS tumors who underwent neurosurgery at our Hospital from Jan 2003 to Dec 2019 were included in the study. The information of all patients was collected from the hospital information system, including diagnosis time, age, gender, anatomical sites, pathological results, etc.
Results:
A total of 17,226 cases of primary CNS tumors were retrospectively analyzed in this study. Among all cases screened, the major tumor types included meningiomas, tumors of neuroepithelial tissue, and pituitary adenomas. The majority of tumors of neuroepithelial tissue were glioblastoma and astrocytoma. Most tumors of neuroepithelial tissue are located in the frontal lobe. Further, the proportion of the frontal lobe increased with the grade. The median age of all patients was 46 years. The incidence of CNS tumors is higher in women than in men.
Conclusions:
Based on this data set, we analyzed various parameters including the types, biological properties, and anatomical site of CNS tumors as well as patients’ age, gender, and race, and provided researchers and clinicians with information on the incidence rate of CNS tumors.

Abstract
Background
The incidence of postoperative nausea and vomiting (PONV) after laparoscopic sleeve gastrectomy (LSG) is up to 80% in China, and the current antiemetic means is mainly the use of antiemetics. This is a randomized, controlled, single-blind study to evaluate the safety and efficacy of auricular acupressure (AA) after LSG.
Methods
A multicenter, randomized, controlled, single-blind, superiority trial (RCT) was designed, and the relevant ethics committee approved the trial protocol. This study used AA as the experimental group and the control group act as a blank group. The primary evaluation index was the INVR score. The secondary indexes were time to first postoperative bed release, time to first anal defecation and time to return to fluid intake after surgery. A total of one hundred patients who met the inclusion and exclusion criteria were randomly grouped, and baseline measurements and outcome indicators were assessed preoperatively and postoperatively, respectively.
Discussion
This trial is a standardized, scientific clinical trial designed to evaluate the effect of AA on the degree of relief of nausea and vomiting and recovery of gastrointestinal function after LSG. We expect the study to provide a basis for promoting this therapy in clinical practice.
