The Improvement of Period of Pseudo Random Number Sequence: an Algebraic Approach
Authors: Ghosh Debashis 
Published: April 2023

Abstract
Linear feedback shift registers are the fundamental structure of pseudo random number generators that are used in formation of channel key. Many methods were proposed for determining linear recurring sequences generated by Linear Feedback Shift Registers to enhance the period. In view of large scale application of this sequence in security and privacy, a clocked controlled linear feedback shift register has been introduced, known as dynamic linear feedback shift register. In this article, we emphasis on dynamic linear feedback shift register scheme using combinatorial design having constant block length and algebraic structure to enhance the period. Such sequence has the vulnerability from attack. Our proposal for designing dynamic linear feedback shift register involves primitive polynomial over a finite fields of prime power. A counter example shown the practical implication of our theory that improve the period of the sequence than existing scheme. Finally an effort was thru on properties of the generated sequence in terms of security aspect.

Assessing GPT-4’s Role as a Co-Collaborator in Scientific Research: A Case Study Analyzing Einstein’s Special Theory of Relativity
Authors: Bryant Steven 
Published: April 2023

Abstract
This study explores GPT-4 as a co-collaborator in scientific research, focusing on evaluating the consistency of Einstein’s Special Relativity Theory equations. GPT-4’s human-level performance makes it a valuable partner in complex research areas with limited access to human experts. Through in-depth conversations, GPT-4 confirmed an inconsistency in the SRT equations, challenging the theory’s validity. This inconsistency persisted except where x=ct, a conclusion reached after GPT-4 advised expanding the range over which the inconsistency was observed. Despite GPT-4’s biases, preference for preserving Einstein’s theory, and mathematical limitations, it contributed to an improved analytical approach and constraint expansion. This paper underscores the benefits and challenges of using GPT-4 in scientific research and highlights the need for caution regarding biases and limitations in large language models. Future research should aim to enhance these models' accuracy, trustworthiness, and objectivity in complex or controversial domains.
Remediation of Pb (II), Cd (II), and Zn (II) from aqueous solutions using porous (styrene–divinylbenzene)/Cu–Ni bimetallic nanocomposite microspheres: continuous fixed-bed column study
Authors: Thrikkykkal Hridya , Antu Rosmin , P. S. Harikumar 
Published: April 2023

Abstract

Bimetallic nanoparticles (BNPs) have been used as a new line of defence against heavy metal contamination among several types of nanoparticles (NPs) due to their enhanced, synergistic activity. In this study, we investigated the adsorption behaviour of porous (styrene–divinylbenzene)/CuNi bimetallic nanocomposite (P(St-DVB)/CuNi BNC) in a continuous flow fixed-bed column and its ability to remove Pb (II), Cd (II), and Zn (II) ions from aqueous solutions. We examined how the initial metal concentration, flow rate, and bed height affected the adsorption characteristics. Experimental results confirmed that the adsorption capacity increased with increase in influent metal concentration and bed height and decreased with increase in flow rate. The breakthrough and the column kinetic parameters were successfully predicted with three mathematical models: Thomas, Yoon–Nelson, and Adams–Bohart models. Both Thomas and Yoon–Nelson models showed good agreement with the experimental results for all the operating conditions. Successful desorption of heavy metals from the P(St-DVB)/CuNi BNC was performed using 0.5 M NaOH solution, and it showed good reusability of the adsorbent during four adsorption–desorption cycles. The results show that P(St-DVB)/CuNi BNC are effective and low-cost adsorbents, and they can be used in real-time large-scale industrial water treatment processes for the removal of heavy metals.

Published: April 2023

The necessity to follow current trends of sustainable development involves more and more participants in the process. Trade companies are an important link in this system of relations. Thus the issues of identifying the key lines of financing green projects in the system of trade enterprise functioning are of great significance. The article shows market mechanisms that ensure implementation of ESG-transformation process in trade. Introduction of green economy principles requires active involvement of all participants of the system in case their economic interests are coordinated. The author characterized the role of trade intermediaries in the system of ESGtransformation. The need to encourage ecologic policy availability in the company was substantiated, as well as publication of non-finance accounting. The problem of shaping closed-cycle economy is still acute, which is connected with realization of priorities of sustainable development and smoothing green-washing schemes. The article formulated priorities of financing green projects in trade and demonstrated trends of developing the most important components, including introduction of new business-strategy aiming at implementation of ESGprinciples. At the same time the author underlines the necessity to form responsible consumption through intensification of advert campaigns and educational projects, including the sphere of trade enterprise work.
Case Report: Culture-negative Prosthetic Valve Endocarditis
Authors: Velazquez Ignacio D. , Woo Kenneth K. , Siddiqui Mohammed , Roy Sion K. 
Published: April 2023

Background::
Prosthetic valve endocarditis can be difficult to diagnose and cause significant
morbidity and mortality, especially when no culture data are available to guide therapy.
Transthoracic and transesophageal echocardiograms, the studies of choice for initial endocarditis
evaluation, can be less reliable due to artifact and post-surgical changes. Some less common forms
of endocarditis may be difficult to culture and, due to their fastidious nature, may delay the identification
of causative organisms. Given the lack of directed antimicrobial treatment, culturenegative
prosthetic valve endocarditis is specifically difficult. A wide differential diagnosis is critical
to make a timely diagnosis and initiate treatment.

Case Presentation:
We present a case of a patient presenting with dyspnea which was found to
have culture-negative endocarditis requiring mitral and aortic valve replacement that ultimately
was complicated with culture-negative prosthetic valve endocarditis. Identifying a culprit organism
made appropriate and timely antimicrobial treatment difficult, ultimately resulting in the patient
dying from endocarditis complications.

Conclusion::
A high index of suspicion is needed when managing infective endocarditis, especially
when prosthetic valves are involved. Diagnostic accuracy of cultures and echocardiography may be
reduced when dealing with prosthetic valve endocarditis; thus, alternative methods of diagnosis
may be required to make a timely diagnosis of causative organisms.

Background:
20(R)-PD, a tetracyclic triterpenoid, is a non-natural saponin present in the form of protopanaxadiol.
Because of its essential biological activities, especially anti-tumor activity, structural modification of 20(R)-PD and
the development of innovative and novel 20(R)-PD derivatives with better anti-tumor activity are increasingly relevant.

Aims:
20(R)-Panaxadiol (20(R)-PD) can inhibit tumor proliferation. Three series of novel 20(R)-PD derivatives were
synthesized by modifying the A-ring.

Objective:
The objective of this work was to synthesize and evaluate the in vitro anti-proliferative activities of 20(R)-
PD derivatives in LNCaP, LS180, and MKN45 cancer cells. Structural modifications were performed at the C-3 position
and A-ring.

Methods:
The in vitro anti-proliferative activities of novel derivatives in LNCaP, LS180, and MKN45 cells were evaluated
by the MTT assay. The effects of compounds 5 and C9 on apoptosis were determined by flow cytometry.

Results:
Compounds 5, B2, C2, C4, C7, C8, C9, C10, and C11 exhibited good anti-proliferative activities in LNCaP,
LS180, and MKN45 cells in vitro. The best anti-proliferative activity was observed for the C-series derivatives with the
introduction of amino acids at the C-3 position. C9 exhibited good potent activity with an IC50 of 2.89 μM.

Conclusion:
Compound C9 is a potential candidate with potent anti-proliferative activity.

Published: April 2023

Objectives:Elaeocarpus ganitrus, a member of the Eleocarpaceae family, is valued in Hinduism and Ayurveda, and is frequently used as a remedy for a variety of illnesses. The plant is reputed to treat a number of stomach issues. The purpose of the study was to produce high-quality scientific data regarding gastroprotective behavior, docking experiments with cholinergic receptors, and HPTLC (with lupeol and ursolic acid). To develop the mechanism of herbal extracts, in vitro anticholinergic and antihistaminic activities were evaluated. Different leaf extracts were treated with various reagents to determine the presence of various metabolites. An examination of the histopathology was conducted to determine the full impact of the extract.Methods:Methanolic extract was chosen for HPTLC investigations after extraction with various solvents. A mobile phase of toluene, ethylacetate, and formic acid (8:2:0.1) was chosen. Molecular docking was utilized to examine how ursolic acid and lupeol are bound to cholinergic receptors (M3). Different extracts (aqueous and ethanolic) were tested for their ability to provide gastroprotection in Wistar rats at different doses (200 and 400 mg/kg).Results:Phytochemical analysis of different extracts showed the presence of different primary and secondary metabolites. HPTLC data showed the presence of both standards. Docking studies exhibited very good interactions with the M3 receptor. Pharmacological studies revealed that extract-treated groups significantly reduced the ulcer index in all of the models mentioned above. The histopathological analysis clearly supports the biochemical studies, which were conducted utilizing various doses and found to be effective in a dose-dependent manner. The in vitro analysis proved that the abovementioned extracts may act as antagonists of acetylcholine and histamine.Conclusion:The data obtained would be valuable for the production of the monograph of the plant and conducting concept-related clinical studies in the future. More investigation is required since the gathered scientific data may lead to new research opportunities.
Usability, Acceptability, and Preliminary Effectiveness of a Peer-Delivered and Technology-Supported Mental Health Intervention for Family Caregivers of People With Dementia: Field Usability Study
Authors: Collins-Pisano Caroline , Leggett Amanda N , Gambee David , Fortuna Karen L 
Published: April 2023

Background
Family caregivers of people with dementia are critical to the quality of life of care recipients and the sustainability of health care systems but face an increased risk of emotional distress and negative physical and mental health outcomes.

Objective
The purpose of this study was to examine the usability, acceptability, and preliminary effectiveness of a technology-based and caregiver-delivered peer support program, the Caregiver Remote Education and Support (CARES) smartphone or tablet app.

Methods
A total of 9 adult family caregivers of people with dementia received the CARES intervention, and 3 former family caregivers of people with dementia were trained to deliver it. Quantitative data were collected at baseline and at the end of the 2-week field usability study. Qualitative data were also collected at the end of the 2-week field usability study.

Results
The field usability study demonstrated that a 2-week peer-delivered and technology-supported mental health intervention designed to improve burden, stress, and strain levels was experienced by former and current family caregivers of people with dementia as acceptable. Current family caregivers rated CARES as above average in usability, whereas the caregiver peer supporters rated CARES as marginally usable. CARES was associated with non–statistically significant improvements in burden, stress, and strain levels.

Conclusions
This field usability study demonstrated that it is possible to train former family caregivers of people with dementia to use technology to deliver a mental health intervention to current family caregivers of people with dementia. Future studies would benefit from a longer trial; a larger sample size; a randomized controlled design; and a control of covariables such as stages of dementia, years providing care, and severity of dementia symptoms.

Published: April 2023

This study aims to empirically prove the effect of executive compensation, executive characteristics, and executive share ownership on tax evading. This study was showed in the consumer goods manufacturing corporation listed on the Indonesia Stock Exchange (IDX) from 2016–2020, using a descriptive associative research method and secondary data. The sampling method used purposive. This research used 16 sample corporations, with a five-year research period of 5 years, so 80 samples were obtained for data processing using Microsoft Excel and the e-View Statistical software applications to analyze descriptive statistics, model conformity tests, classical assumption tests, coefficients of determination (R2), linear regression analysis of panel data, statistical test F and statistical test t. Results of statistical test F executive-compensation variables, executive-characteristics, and decision-making-shareholdings affect tax avoidance. The statistical test t of the executive compensation variable partially has a optimistic and significant effect on dividend payments—however, the executive's variable characteristics and the executive shares' ownership harm tax evading.
Interaction Effect of Foreign Language and Obedience Pressure on Ethical Judgment in Accounting: Evidence from Japan
Authors: Sugahara Satoshi , Tsunogaya Noriyuki , Kim Jong-Hoon 
Published: April 2023

ABSTRACT
This study examines the interaction effect of foreign language and obedience pressure from superiors on the ethical judgment in an auditing context. We conducted a 2 × 2 between-participants experiment with language and obedience pressure as independent variables. Participants are accounting students from eight leading universities in Japan to proxy entry-level auditing professionals. They were asked to provide their judgments based on a consolidation reporting scenario. We found that, under obedience pressure, foreign language use makes one’s judgment less aligned with the superior’s preference (less compliant) than the use of the native language. These results provide new insights regarding the potential boundary of the foreign language effect in auditing issues.
How Does Risk Tolerance Reflected in National Culture Affect Pay-Performance Sensitivity?
Authors: Free Mitchell , Kent Pamela , Qu Xin , Yao Daifei 
Published: April 2023

ABSTRACT
The standard principal-agent model predicts that, ceteris paribus, a negative relation exists between firm risk and CEO incentives or pay-performance sensitivity. We examine how a CEO’s risk tolerance (captured by national culture) affects pay-performance sensitivity using international data from 29 countries. We find that CEOs from countries with high (low) risk tolerance are associated with high (low) pay-performance sensitivity, suggesting that they require a low (high) risk premium. We contribute to the CEO compensation literature by introducing CEO risk tolerance, an overlooked factor, into CEO compensation contracts.
Sunlight is the Best Disinfectant: Real-Time Comment Letters and Large M&As in China
Authors: Yang Shuo 
Published: April 2023

ABSTRACT
This paper investigates how communications between regulators and firms through comment letters affect the outcomes of large mergers and acquisitions (M&As) in China. Unlike the U.S. Securities and Exchange Commission (SEC), which uses comment letters to improve the accuracy of the measurement of deals, Chinese regulators worry about controlling shareholders' self-dealing and use real-time comment letters to expose suspicious deal specifics and to create pressure for controlling shareholders to back down. I find that the Chinese stock exchanges issue more severe comment letters on deal filings that indicate controlling shareholders’ expropriation of minority shareholders. More severe comment letters are associated with a lower market response to the receipt of letters, predict a higher probability of voluntary deal cancellation by management, and indirectly increase the probability of deal withdrawal and lengthen the processing time for equity-funded deals by affecting the approving body’s scrutiny level.
The Anticipation of Mandatory Audit Firm Rotation and Audit Quality
Authors: Friedrich Christian , Pappert Nicolas , Quick Reiner 
Published: April 2023

ABSTRACT
Researchers and regulators regularly debate whether mandatory audit firm rotation affects audit quality. Theoretically, rotation might improve auditor independence but impair competence. In 2014, the European Commission mandated audit firm rotation for public-interest entities, starting from 2020 for nonfinancial firms. However, any auditor change in the transition period could already be interpreted in light of the upcoming mandatory rotation regime, consistent with anecdotal evidence on such interpretations. These changes provide a unique setting because auditors have strong incentives to build a reputation for high-quality audits when choosing to participate in the market for rotations during the transition period. Using a balanced panel of 287 German firms and data from 2014 through 2019, we hypothesize and find lower discretionary accruals, abnormal working capital accruals, and total accruals in the first year after rotation. This effect is restricted to smaller public companies.
