Noise immunity of coherent reception M-PSK signals with a rectangular envelope in a hydroacoustic communication channel
Authors:   RTU MIREA, 119454, Moscow, prospekt Vernadskogo, 78, Denisov V.E.
Published: January 2023

The main purpose of this work is to develop a methodology for determining the parameters of M-PSK signals, in which the signals become relatively invariant to frequent distortions in the marine environment. The frequency distortions of the signals are caused by the uneven frequency response of the attenuation of the marine environment. The main part of this technique is to assess the effect of frequency distortion of signals on the noise immunity of reception. To do this, the error probabilities of the receiver of M-PSK signals determined, which is optimal in the absence of distortion. Methods. The provisions of applied hydroacoustics, the theory of random processes and the theory of transmission of discrete messages are used. The main content. The paper considered a model of a single-beam hydroacoustic communication channel, characteristic of the deep sea, when the receiver or transmitter is located in the depths of the sea. The transmission coefficient of the channel is used as a transmission coefficient with a Gaussian amplitude - frequency response and a linear phase-frequency response. The additive boundary of the probability of error in the coherent reception of M-PSK signals with a rectangular envelope is determined. As a receiver, a coherent receiver is considered, optimal by the criterion of maximum similarity under the action of white Gaussian noise and the absence of distortion in the marine environment. A logarithmic measure of increasing the probability of error is introduced, which characterizes the deterioration of noise immunity due to frequency distortions in the channel. For some typical cases, the values of signal parameters that are relatively invariant to frequency distortions in the marine environment are determined. Results. Expressions are found for the upper bound of the probability of error of coherent signal receivers of M-PSK signals with a rectangular envelope for M = 2, 4, 8, 16, 32. A logarithmic measure of the relative increase in the probability of error compared to the case of the absence of distortions is introduced. The functional dependence of this measure is determined on the duration of sending the signal, the carrier frequency and the number of phases of the signal, as well as on the communication range and the signal-to-noise ratio. On the plane of the carrier frequency, the duration of the signal, for each type of signal, the boundary of the region above which the signals are relatively invariant to frequency distortions in the marine environment is constructed. For the communication range R = 3 km and the carrier frequency f0 = 30 kHz, the minimum values of the duration of invariant signals are given.

A Day in the Life of ChatGPT as a researcher: Sustainable and Efficient Machine Learning - A Review of Sparsity Techniques and Future Research Directions
Authors: Srivastava Mashrin
Published: January 2023

The International Conference on Machine Learning (ICML) recently decided to prohibit producing/generating ICML paper text using large-scale language models this year (2023) icm [2023]. This decision was made due to the conference organizers’ desire to thoroughly observe, investigate, and consider the implications of using these models for the reviewing and publication process. This led to a curiosity in evaluating the capabilities of large language models like ChatGPT in producing a full conference paper on their own. To our knowledge, this is the first time that a paper has been completely generated by ChatGPT, from selecting the topic to creating all of the content. The goal of this paper is for the community to evaluate its performance and welcome review for the same. The prompts used is mentioned in the appendix. Here, ChatGPT was tasked to write a paper for an International Conference on Learning Representations (ICLR) workshop on Sparsity in Neural Networks: On practical limitations and tradeoffs between sustainability and efficiency. The abstract for the paper is: The sustainability and efficiency of machine learning algorithms are becoming increasingly important as the demand for machine learning grows and the complexity and scale of models continue to increase. The incorporation of sparsity into machine learning algorithms has the potential to address these issues by reducing the size and complexity of models and improving their efficiency and sustainability. In this paper, we review the current state of the art in sparsity for machine learning and discuss the challenges and tradeoffs of its application. We also suggest potential directions for future research in this area, including the development of novel compression algorithms and hardware architectures that can support the efficient training and analysis of large-scale, compressed neural networks, as well as the exploration of domain-specific approaches to effectively incorporate sparsity into machine learning algorithms.

Published: January 2023

Academia in the United States continues to grapple with its longstanding history of racial discrimination and its active perpetuation of racial disparities. To this end, universities and academic societies must grow in ways that reduce racial minoritization and foster racial equity. What are the effective and long-lasting approaches we as academics should prioritize to promote racial equity in our academic communities? To address this, the authors held a diversity, equity, and inclusion (DEI) panel during the Society for Behavioral Neuroendocrinology 2022 annual meeting, and in the following commentary synthesize the panelists’ recommendations for fostering racial equity in the US academic community.
Conditional Process Analysis for Two-Instance Repeated-Measures Designs
Authors: Montoya Amanda Kay
Published: January 2023

Models where some part of a mediation is moderated (conditional process models) are commonly used in psychology research, allowing for better understanding of the process by which a focal predictor affects an outcome through a mediator depends on moderating variables. Methodological developments in conditional process analysis have focused on between-subject designs. However, two-instance repeated-measures designs, where each subject is measured twice: once in each of two instances, are also very common. Research on how to statistically test mediation, moderation, and conditional process models in these designs has lagged behind. Judd, Kenny, and McClelland (2001) introduced a piecewise method for testing for mediation, that Montoya and Hayes (2017) then translated that method to a path-analytic approach, allowing for a quantification of the indirect effect. Moderation analysis in these designs has been described by Judd, McClelland, and Smith (1996), Judd et al. (2001), and Montoya (2018). The generalization to conditional process analysis remains incomplete. I propose a general conditional process model for two-instance repeated-measures designs with one moderator and one mediator. Simplifications of this general model correspond to more commonly used moderated mediation models, such as first-stage and second-stage conditional process analysis. Two applied examples show both how to conduct the analysis using MEMORE, a free and easy-to-use macro for SPSS and SAS, and how to interpret the results of such an analysis. Alternative methods for evaluating moderated mediation in two-instance repeated-measures designs using multilevel approaches are also discussed.

Published: January 2023

Due to today's rapid socioeconomic expansion and environmental concerns, many modern civilizations are interested in researching alternate energy options, notably renewable ones. In this sense, a Micro-grid (MG) of multiple renewable energy sources can help achieve the intended goals while delivering electricity more efficiently, affordably, and safely. This paper presents an expert multi-objective Glowworm Swarm Optimization Algorithm (GSO) for optimal operation of a typical MG with Renewable Energy Sources (RESs). The objective is to minimize both the overall operating cost and the net emission. The proposed algorithm is tested on a typical MG, and its superior performance is compared to those from other evolutionary algorithms.

Published: January 2023

The unknown crystalline samples like minerals, inorganic compounds etc. are identified mostly with the help of X-ray diffraction (XRD). More than 25 Nobel prizes have been awarded to the works based on it. The identification of the solids are essential for the research in various streams of science like Material, Environmental, Geo, Engineering and Biology. The XRD is based on Bragg’s law. The diffraction pattern obtained after passing the X-ray through interatomic slit is the main source of the structure. It was first demonstrated by Max von Laue (1912). The XRD is now attached with instrumental and computational tools. This paper focus on different steps for the indexing of an X-ray diffraction pattern, identifying the Bravais lattice, and calculating the lattice parameters of the cubic (Al) and non-cubic (Ti) system that are the starting elements we have used for the preparation of MXene. We have used the experimental and mathematical ways for the determinations of the intended structural values. The values obtained were in well agreement with the standard data.

Authors: Ramdani Zulmi , Natanel Yonathan , Busro Busro
Published: January 2023

Religious moderation is considered one of the crucial issues discussed by many parties. This circumstance is evidenced by varied rules and facts, making it an indicator of the nation's welfare. The lack of research that specifically addressed the correlation between religious moderation and psychological attributes was one reason why this study was conducted. Hence, the purpose of the present research was to determine the role of religious moderation on the life satisfaction of generation Z Muslim students. A quantitative design engaging a causal approach was employed to measure the significance of the role of religious moderation on the life satisfaction of generation Z Muslims. 453 respondents selected using the purposive sampling technique participated in this study. To collect the data, researchers administered two tested measuring instruments that indicated good psychometric properties. The regression analysis results revealed a significant impact of religious moderation on the life satisfaction of generation Z Muslim students. Meanwhile, the categorization of respondents confirmed that most of them had moderate and high levels of understanding of religious moderation. This study concluded that to achieve high life satisfaction, religious moderation could be considered an essential aspect of social life. Correspondingly, the findings could be implied as a reference for policymakers at Islamic educational institutions in forming an awareness of the importance of religious moderation among generation Z Muslims studying at Islamic universities in Indonesia.

Trauma Patients at Risk of In-Hospital Mortality
Authors: Pswarayi R
Published: January 2023

The trauma incidence in South Africa is significantly high and forms one of the top-five causes of unnatural death. Thus, one of the higher incidences of trauma across the world. Subsequently the in-hospital mortality forms a high burden of disease on the health systems in South African health care facilities. Therefore, analysing the incidence of trauma and the various mechanisms of trauma allows for in-hospital trauma mortalities to assessed. The aim of this study was to analyse the in-hospital mortality distribution factors at a Johannesburg Trauma unit over an eight-year retrospective review from 01 January 2005 –31 December 2012 and Analysis of Trauma Bank data forms at Charlotte Maxeke Johannesburg Academic Hospital (CMJAH). Looking at demographics, physiological parameters, mechanism of Injury, Injury Severity Score (ISS) and New Injury Severity Score (NISS). Ethics through the Wits Ethics Committee was obtained. The Statistica V8 application was used to analyse the data that was collected and a P value of <0.05 was reported as significant. A total of 18, 087 Priority 1 patients were reviewed in this study. This sample demonstrated the 21-45 years of age group was the most affected trauma group (87.3%). Penetrating injuries (Stab and gunshot wounds) had the highest incidence yet lower mortalities. However, blunt injuries (ranging from Pedestrian- and Motor- vehicle crashes, blunt assaults, falls and burns) had lower incidences and higher mortalities. The highest in-hospital mortality was due to burns patients (22.56%) followed by pedestrian vehicle crashes patients affecting the predominantly young male population. Poor probability of survival was demonstrated amongst Motor Vehicle Crashes (Ps 44%) and Motorbike Crashes (34%), and PVCs.

Study Design: Retrospective cohort.Purpose: To determine (1) the effects of serotonin reuptake inhibitors in pseudarthrosis rates after anterior cervical decompression and fusion (ACDF) and (2) to identify patient-reported outcome measures in patients taking serotonin reuptake inhibitors. Overview of Literature: Recent literature suggests that selective serotonin reuptake inhibitors (SSRIs) may inhibit fracture healing via downregulation of osteoblast differentiation. Spinal fusion supplementation with osteoblast-rich substances enhances spinal fusion, thus SSRIs may be detrimental.Methods: Patients with 1-year postoperative dynamic cervical spine radiographs following ACDF were grouped into serotonin reuptake inhibitor prescriptions (SSRI, serotonin-norepinephrine reuptake inhibitor [SNRI], or tricyclic antidepressant [TCA]) and no prescription (atypical antidepressant or no antidepressant). Pseudarthrosis was defined as ≥1 mm interspinous process motion on dynamic radiographs. Logistic regression models were controlled for confounding to analyze pseudarthrosis rates. Alpha was set at p - values of <0.05.Results: Of the 523 patients who meet the inclusion criteria, 137 (26.2%) were prescribed an SSRI, SNRI, or TCA. Patients with these prescriptions were more likely to have pseudarthrosis (p =0.008) but not a revision surgery due to pseudarthrosis (p =0.219). Additionally, these patients had worse 1-year postoperative mental component summary (MCS)-12 (p =0.015) and Neck Disability Index (NDI) (p =0.006). The multivariate logistic regression analysis identified SSRI/SNRI/TCA use (odds ratio [OR], 1.82; 95% confidence interval [CI], 1.11–2.99; p =0.018) and construct length (OR, 1.91; 95% CI, 1.50–2.44; p <0.001) as pseudarthrosis predictors. A SSRI/SNRI/TCA prescription was a revision surgery predictor due to adjacent segment disease on univariate analysis (OR, 2.51; p =0.035) but not on multivariate logistic regression analysis (OR, 2.24; p =0.10).Conclusions: Patients taking serotonin reuptake-inhibiting antidepressants are at increased risk of worse postoperative outcome scores, including NDI and MCS-12, likely due to their underlying depression. This may contribute to their greater likelihood of having adjacent segment surgery. Additionally, preoperative use of serotonin reuptake inhibitors in patients undergoing an ACDF is a predictor of radiographic pseudarthrosis but not pseudarthrosis revision.

Study Design: This is a single-center retrospective cohort study with a university hospital setting.Purpose: This study aims to evaluate the short-term course of physical function and walking ability after intramedullary spinal cord tumor (ISCT) resection and predict walking independence 1 year after surgery.Overview of Literature: Although several reports have shown the postoperative functional prognosis of spinal intramedullary tumors with long-term follow-up, no reports have identified the predictors associated with the functional outcome at an early stage. Methods: A total of 79 individuals who underwent ISCT resection at our institute between 2014 and 2019 were enrolled in the study, whose preoperative walking state was independent ambulator regardless of cane support with the Functional Independence Measure Locomotor Scale (FIM-L) score of ≥6. The FIM-L, the American Spinal Injury Association (ASIA) motor and sensory scores in the lower extremities, and the Walking Index for Spinal Cord Injury II (WISCI II) were assessed for walking independence, lower-limb function, and walking ability, respectively. These evaluations were performed at 4 time points: preoperatively, 1 week (1W), 2 weeks (2W), and 1 year after surgery.Results: In the early phase after surgery, 71% and 43% of the participants were nonindependent ambulators at 1W and 2W, respectively. Histopathology indicated that patients with solid tumors (ependymoma, astrocytoma, or lipoma) showed significantly lower indices at 1W and 2W than those with vascular tumors (hemangioblastoma or cavernous hemangioma). Regarding tumor location, thoracic cases exhibited poorer lower-limb function at 1W and 2W and poorer walking ability at 2W than cervical cases. According to the receiver operating characteristic (ROC) analysis, 2 WISCI II points at 2W had the highest sensitivity (100%) and specificity (92.2%) in predicting the level of walking independence at 1 year postoperatively (the area under the ROC curve was 0.99 (95% confidence interval, 0.93–1.00).Conclusions: The higher the lower-limb function scores in the early phase, the better the improvement in walking ability is predicted 1 year after ISCT resection.

Published: January 2023

This article aims to determine the way languages are represented in the linguistic landscape of the city of Yakutsk, in particular, the representation of Sakha and ethnic (minority) languages: Even, Evenki, Yukaghir, Chukchi, and Dolgan. To meet this aim, the following objectives were completed: a systematic compilation of texts from outdoor signs available on two main streets of Yakutsk; field research on the linguistic landscape of the city; formation of a linguistic corpus of urban texts; and a comprehensive analysis of the linguistic landscape. This analysis solves two research questions: 1) What languages are represented in the linguistic landscape of Yakutsk and what is their share? 2) What are some of the characteristics of bilingual/multilingual signs?
