Kinetic Exploration of Nanoscale Polymorphs through Interface Energy Adjustment
Authors: Sakakibara Masaya , Nakamuro Takayuki , Nakamura Eiichi
Published: March 2024

Traditionally, the study of polymorphism has relied on thermodynamics and mass-averaged measurements. This work introduces a novel approach by combining kinetic analysis and statistical mechanics with electron microscopic imaging to observe phase transitions directly. We demonstrate a remarkable impact of the crystal size on the kinetic stability of polymorphs at nanoscale domains, enabling in situ manipulation of phase transitions at 298 K through interface energy adjustments by size reduction. Starting with the B1 NaI polymorph, we synthesized the previously unknown B2 polymorph upon size reduction. Starting from the CsCl liquid phase, we produced B1, previously described only above 749 K, and then B2 via quick martensitic transformation.

From time immemorial, people have sought to improve their body and appearance by resorting to various medical, non-drug and surgical interventions. The most advanced direction in this context has been and remains facial cosmetic surgery, which, being a kind of standard that allows you to achieve perfection, encourages people to change their appearance in an operative way, which is not always justified. The most common and sought after desire of people when visiting a plastic surgeon is to change the shape of the nose. The main motive for rhinoplasty is low self-esteem, dissatisfaction with the shape and size of the nose, which, in their opinion, prevents them from achieving success in their personal lives, building a career, etc. As a rule, most of these people are people of ethnic groups who seek to “Europeanize” their nose and face according to modern aesthetic canons, people with dysmorphophobia, young girls and boys. Often there are cases when patients, having not received the desired result, make claims to surgeons and embark on litigation. Therefore, when planning rhinoplasty, it is necessary to find out several important questions: the main psychological reasons that motivated rhinoplasty; whether the patient has mental deviations what are the external influences and internal deviations. Patients presenting with the following features are at high risk and should give surgeons reason to reconsider their rhinoplasty.
Energy spectrum and magnetic properties of the decorated spin ladder models of nanomagnets on the base of polymeric transition metal compounds
Authors: Cheranovskii Vladyslav , Mukhomodiarova Viktoriia
Published: March 2024

The work is devoted to the theoretical study of the energy spectrum and low-temperature magnetic properties of the decorated spin-ladder model with the polyacene topology and the three types of the site spins. On the base of cluster expansion technique an approximate analytical treatment of lowest part of the energy spectra of two isomeric ladder structures was given. It is shown that the ladder model with singlet ground state is more stable than its isomeric analog with the macroscopic ground state spin. In addition, the numerical study of field dependence of low-temperature magnetization of 8- spin clusters of both ladder models was performed by means of exact diagonalization method. On the base of these results, it was shown the presence of an intermediate plateau in low-temperature magnetization profile of the above spin ladder models.
Internal validation parameters of linear regression equations in QSAR problem
Authors: Khristenko Inna , Ivanov Volodymyr
Published: March 2024

The article discusses a set of internal validation parameters that are (or can be) used to describe the quality of regression models in quantitative structure-activity relationship problems. Among these parameters there are well known determination coefficient, root mean square deviation, mean absolute error, etc. Also the indices based at Kullback-Leibler divergence as a measure of distance between two sets have been investigated. All the parameters (indices) were calculated for several regression models which describe boiling point of saturated hydrocarbons (alkanes). Regression models include a four-component additive scheme and equations describing the property as a function of topological indices. The two types of regressions based on these indices are linear dependencies on only one topological index and linear dependencies on topological index and the number of carbon atoms in the hydrocarbon. Various linear regression equations have been described with internal validation parameters that evaluate the quality of the equations from different perspectives. It is shown that a wide set of test parameters is not only an additional yet alternative description of regression models, but also provides the most complete description of the predictive characteristics and quality of the obtained regression model.

Authors: Lebed Alexander , Mchedlov-Petrossyan Nikolay , Filatov Dmitriy , Goga Sergey
Published: March 2024

This paper presents results of quantum-chemical study of proton exchange equilibrium between acetone (AC) and dimethyl sulfoxide (DMSO). Basing on the previous study of acid-base equilibria in AC with small additives of DMSO, the most probable composition of the lyonium ion is taken as H(DMSO)2+. The equilibrium geometries and energies of solvents molecules and all possible combinations of proton complexes with one or two solvent molecules were calculated in DFT level of theory using B3LYP functional and 6-31G++(d,p) basis set. The energies of solvated proton complexes were then calculated using PCM method. The energy change corresponding to the equilibrium H(AС)2+ + 2 DMSO ⇄ H(DMSO)2+ + 2 AС is –63.1 kJ mol–1 in the gas phase, which is in qualitative agreement with the standard Gibbs energy data, obtained experimentally in the gas phase by Kebarle’s group, –77.6 kJ mol–1, and with ΔGo298 = –49.3 kJ mol–1 for AC solution with small additions of DMSO, determined by the Guss and Kolthoff method.

Microplastic contamination in the Chennai coastal region is a growing concern due to the intake of abandoned garbage from various sources. This study aimed to assess the extent of microplastic contamination by analyzing microplastic trash collected from 25 spots along the Tamil Nadu coast, spanning a distance of 1076 kilometers. The results revealed that microplastic contamination was more prevalent during higher wave conditions compared to lower tides. Shorelines near riverbanks exhibited significantly higher quantities of microplastics than those affected by fisheries and tourist activities. The main types of microplastics found were polyethylene, polypropylene, and polystyrene, with plastic shards comprising the majority of the trash (47-50%). Furthermore, analyses of fish species collected from shore regions showed that 10.1% of the fishes had consumed plastic particles. This emphasizes the potential risk of microplastics entering the marine food chain. The study highlights the need for microplastic filtering from estuaries, coastline waters, and other potential sources. In conclusion, microplastic contamination poses a serious hazard to the Chennai coastal region. Urgent measures are required to mitigate and reduce microplastic pollution, particularly near river openings, to protect the marine ecosystem and the food chain. Efforts should focus on preventing the entry of microplastics into the environment and promoting sustainable waste management practices to safeguard the coastal ecosystem.

Published: March 2024

In the rapidly developing digital era, information systems have become an important element in increasing efficiency and effectiveness in various activities. As an important part of public services, queuing services withstand significant challenges in managing rapid population growth. Long waiting times and inefficient queue management can result in user dissatisfaction, increased workload for service providers, and potentially harm productivity. This research aims to overcome these challenges by identifying, pivoting, and creating an innovative information system integrated with the popular cross-platform application, WhatsApp. The main focus is automating queue service management to increase efficiency and user convenience. The resulting system is expected to provide significant changes in public services, reduce waiting times, and make queue management easier. The Unified Modeling Language (UML) methodology is used in the design of this system, providing systematic guidance to achieve these goals. In this research, we identify problems, user needs, functional requirements, and non-functional systems, including queue registration, queue management, user management, and service management. The results include use case diagrams, activity diagrams, sequence diagrams, and class diagrams, which provide a detailed overview of various aspects of the system. The results of this research can serve as a guide for application developers and demonstrate the benefits of UML in designing complex information systems.
Assessing the Efficiency and Role of Duckweed (Lemna Minor) in the Removal of Pollutants from Wastewater Treatment Plant Secondary Clarifier Tanks: A Comprehensive Review

Aquatic plants, including duckweed (Lemna minor), are increasingly utilized in sewage and wastewater treat-ment to improve pollution parameters and organic matter removal. This study aimed to investigate the impacts and efficacy of duckweed in secondary clarifier tanks in a conventional biological treatment facility. The per-formance of four secondary clarifiers with and without duckweed was compared based on water quality efflu-ent and settling characteristics. As per the experiment results, the secondary clarifier tank with duckweed demonstrated higher removal efficiency for chemical oxygen demand (COD), biological oxygen demand (BOD5), ammonium, phosphate, total nitrogen (TN), and total phosphorus (TP) – of 70%, 75%, 72%, 82%, 67%, and 96%, respectively, compared to the tank without duckweed. The concentration of suspended solids in the effluent and sludge volume index (SVI) values were similar in both settings. The research findings suggest that duckweed can contribute to the treatment efficiency of conventional biological treatment plants, thus re-ducing the need for tertiary nutrient removal. Additionally, the cost-effectiveness of treatment with duckweed and its reuse as fertilizer and animal fodder make it a valuable resource. The optimal temperature for duck-weed growth is approx. +26°C, and it is influenced by sunlight and temperature more than nutrient concentra-tions.

Introduction: Permanent vascular access (arteriovenous fistula (AVF), arteriovenous graft (AVG)) is susceptible to acute events that reduce patency. The temporary central venous catheter (CVC) constitutes bridging therapy for primary vascular access dysfunction. The impact of “residence time” on the rate of dysfunction/thrombosis or infection remains to be explored. AIM: 1) To evaluate the impact of CVC residence time on outcomes (infection or Thrombosis/dysfunction) in consecutive temporary CVCs adjusted for the insertion site (upper site vs. lower site). 2) To establish a cut-off resident time. Patients and methods: Seventeen prevalent hemodialysis patients with three consecutive CVCs are followed up prospectively in an observational study for a period equivalent to the permanence of the CVCs. The data is recorded at the beginning of the CVC time. The diagnosis of catheter-related bloodstream infection and thrombosis/dysfunction is made following the K-Doqi 2019 guidelines. Statistical analysis: Seventeen hemodialysis patients (51 CVCs) were included. The ‘CVC resident time’ of each individual patient ((i.e. βcoefficient (log-transformed)*AUC)) was determined using LMM and then inserted into multivariate Cox models to assess infection and dysfunction/thrombosis outcomes (Joint Models). The AUC was calculated at various baseline levels of CVC time (10th……50th percentile). The cut-off point for thrombosis in CVC time corresponds to the mean of the CVC time at the 30th percentile of all CVCs. Results: The CVC time is different for CVC’s site insertion and sequence. From the analysis of multivariate joint models, CVC resident time appears not to be significant for infection, but heterogenicity for the insertion site (ref3-4=upper site) is significant for the outcome of thrombosis/dysfunction. From the study of survival analysis, the free survival from outcomes by CVC site insertion appears to be significant for thrombosis/dysfunction. The average time of CVCs’ calculation at the 30th percentile is 14 days (cut-off). Conclusion: No tunneled hemodialysis Catheter (NTHC) residence time is considered not to be a risk factor for infection, but it represents a risk factor for lower access thrombosis. After the cut-off time of 14 days, the advantage of the higher NTHCs is lost.

Introduction. Multiple sclerosis (MS) is a chronic autoimmune and neurodegenerative disease of the central nervous system (CNS). High-dose immunosuppressive therapy with autologous hematopoietic stem cell transplantation (HDIT–AHSCT) is the most eff ective method of treating MS, which has a positive eff ect on the quality of life of patients and inhibition of the progression of disability.

The aim of the study was to analyze the dynamics of quality of life in patients with MS who underwent the HDIT– AHSCT method in groups with diff erent clinical effi  cacy of this method.

Material and methods. The single-center observational study included patients with MS (n = 21, mean age 35.5 ± 6.2 (28–50) years; men/women — 11/10; remitting MS (RMS) n = 16, secondary-progressive (SPMS) n = 4, primaryprogressive (PPMS) n = 1), after HDIT–AHSCT (cyclophosphamide-rituximab conditioning regimen). Assessment of the quality of life (SF-36, FAMS, CSP-MS42, HADS) and the degree of disability in all patients was carried out before and 12 months after HDIT–AHSCT.

Results. 12 months after HDIT–AHSCT, more than 50% of patients showed signifi cant improvement in quality of life according to the scales of viability and social functioning of the SF-36 questionnaire, as well as according to the scales of general well-being and additional problems of the FAMS questionnaire. 57% of patients had a signifi cant improvement in the overall FAMS score. According to the CSP-MS42 questionnaire, a decrease in weakness (p < 0.05), feelings of constant fatigue and rapid fatigue during exercise was revealed. After transplantation, there was a slight decrease in anxiety (p = 0.91) and a signifi cant decrease in depression (p = 0.011).

Conclusion. The expected dynamics was established: in patients with clinical improvement, there was an improvement in the quality of life for most indicators; in patients with stabilization, most quality of life indicators were similar before and after HDIT–AHSCT; with clinical deterioration after HDIT–AHSCT, quality of life parameters worsened. These data indicate the expediency of further optimization of patient selection criteria and various stages of the HDIT–AHSCT in order to obtain optimal clinical results and, accordingly, improve the quality of life of patients.
Paraneoplastic neurological syndromes: upgraded approaches to diagnosis
Authors: Grigoryeva V. N. , Ruina E. A.
Published: March 2024

Paraneoplastic neurological syndromes (PNNS) are neurological disorders due to autoimmune attack on the nervous system, induced by a tumor remote from these structures. The existence of relatively stable associations between the neurological syndrome, the type of antineuronal antibodies (Ab) and the nature of tumor has been proven. At the same time, there are no pathognomonic combinations of this kind: the same antibodies can be detected in diff erent types of tumors and in diff erent syndromes. In addition, level of reliability of the diagnosis of PNNS is considered, taking into account the phenotype of the neurological disorder, the presence of certain antibodies in the blood serum, the verifi cation of oncopathology and the duration of the observation for the patient.

Community health workers hold an important role in health promotion and prevention of dengue fever. In the Jumantik program, the community health workers sought to find any mosquito larvae at the houses and report the findings to the community health centers (Puskesmas). Nevertheless, the reporting process is still paper-based and complex. This study aims to develop a mobile application that facilitates the reporting process to be more user-friendly and practical for community health workers. We used a system framework with the input-process-output scheme in developing this application. A review of the Puskesmas program and interviews with Puskesmas officers and community health workers were performed to obtain input. The application was tested among programmers and users (i.e., community health workers) to understand its usability and applicability. The users were able to input the data, upload photos, and produce the report. We invited about fifty users to test this application. They provided positive responses and were satisfied with the final product of this mobile application. However, they also suggest adding some functions related to the data storage and availability of this application in the Apple store

Tax avoidance and transparency activities influence the value of the company because taxation is a reduction of profits. The smaller the profit obtained, the greater the tax paid. On the one hand, if the level of transparency of the company is high, it can reduce the level of managerial opportunistic behavior. So that the impact of this will benefit the company and its shareholders. This study aims to examine how the impact of tax avoidance and transparency on company value. Where the result is tax avoidance has a significant effect of 0.000 <0.05 and the t-test value of 6.149> 2.048 on the company's value, so the tax avoidance variable has a significant negative effect on firm value. While transparency has a significant effect of 0.001 <0.05 and for the t-test value of 3,649 > 2,048 on Company Value. So that the transparency of its influence is positive on the value of the company, the higher the level of transparency of the company doing tax avoidance, the higher the value/price of the company.

The value of the company will be reflected in its share price, so the stock price can be said to be a measure of the company's success. In addition, it can also be seen through the condition of profits and cash flow turnover. The better the company's performance, the share price will increase, so it is natural for issuers to maintain their share prices because they reflect the actual condition of the company. This study aims to analyze the effect of operating cash flow, investment cash flow, funding cash flow, and net income on stock prices. This type of research is quantitative associative. The population in this study is the financial statements of the company Kalbe Farma Tbk. the 2013-2020 period, while the samples taken are all financial reports at the company Kalbe Farma Tbk. period 2013-2020 and the sampling was taken through a saturated sample (non-purposive sampling).

Objetivo: identificar percepções e crenças acerca do ageismo vivenciado pela pessoa idosa. Metodologia: estudo qualitativo, elaborado por meio de grupo focal, realizado em Centro de Convivência da Pessoa Idosa, localizado no interior de Pernambuco. Foram incluídas pessoas idosas residentes do município que frequentava a instituição com domínio cognitivo preservado, avaliado por meio do Miniexame do Estado Mental. O grupo focal foi conduzido pela seguinte pergunta norteadora: “Você já se sentiu triste por ser idoso?”. Para captação legível do áudio utilizou-se dois aparelhos de MP3. O estudo seguiu as normas de pesquisa com seres humanos e foi aprovado pelo comitê de ética. Resultados: Observou-se que o ageismo era vivenciado em situações do cotidiano, como filas, salas de atendimento e locais públicos. Embora os participantes relataram que a velhice não é um problema, eles pontuaram limitações acerca da pessoa idosa na comunidade, com o preconceito e estereótipos do envelhecimento. Com a análise das falas, foi possível identificar termos pejorativos e preconceituosos associados ao envelhecimento, como: “velho”, “gagá” e “brôca”, que associa-se a baixa autoestima e autoimagem negativa relatado durante o grupo focal. Conclusão: foi possível identificar informações e particularidades vivenciadas pela pessoa idosa acerca do ageismo, no qual fornece subsídios para desenvolvimento de intervenções em saúde para o enfrentamento e disseminação de informações sobre a temática.
Millions of Students are (Still) Above Grade Level: Achievement and Achievement Variability in Mathematics and Reading Before and During COVID-19 in the United States
Authors: Rambo-Hernandez Karen E , Makel Matthew , Koehler Noah
Published: March 2024

According to Peters et al. (2017), millions of students have already demonstrated they know the material slated to be taught that year. Consequently, grade-level standards are unlikely to be appropriately challenging for these students. In this paper, we conceptually replicate and extend this study. Using data from schools that administered the Renaissance Star assessment in fall 2018 and fall 2021, we quantify pre-COVID and mid-COVID average achievement and variance in achievement in mathematics and reading in fifth grade and estimate the grade level of instruction needed for students. Our results indicate that (a) achievement dropped during COVID-19 relative to pre-COVID, but the drop in mathematics was larger, and (b) achievement variability increased during COVID-19, but the variability in reading was slightly more pronounced. Further, our results replicated Peters et al.’s (2017) results—large numbers of students still performed above grade level, and substantial variability in achievement was present within schools.

Published: March 2024

The theory of cosmic inflation is one of the most popular and accepted theories for explaining the expansion and evolution of the universe. According to the theory, the early Universe expanded exponentially for a fraction of a second, between 10^−33 and 10^−32 seconds, after the Big Bang. Following this period, the universe expanded at a slower but accelerating rate. The popularity of this theory is attributed to its ability to solve several fundamental peculiarities about ouruniverse, particularly the horizon problem (homogeneity problem), flatness problem, and lack of magnetic monopoles. Early theories primarily conceptualized by Alan Guth, who sought to explain the lack of magnetic monopoles, introduce vacuums, quantum fluctuations and tunneling, inflatons, and how inflation is incurred by false vacuum decay. Proponents like Andrei Linde later pose the inflaton field’s “slow roll” conditions, differing from quantum tunneling describedby Guth. In addition, he proposed how inflation could eternally sustain a multiverse in an infinite expanding fractal, with different physical properties defining each pocket universe. Most recently, Paul Steinhardt’s development of cyclic cosmology and the concept of repeating “Big Bounces” introduced reformed ways to explain the presence of dark energy and universal homogeneity. In this review, we aim to document the evolution of inflation based on these different theories and to make conclusions on their successes and shortcomings in answering cosmology’s unexplained fundamental questions.

Geospatial Modeling and Mapping of Soil Erosion in India

Soil erosion generally removes the topmost fertile layer of soil, affecting agricultural productivity on a larger scale. As a significant portion of the Indian economy depends on agricultural productivity, granular assessment of the impact of soil erosion becomes critical. However, a national-scale assessment of soil erosion and an impact classification system currently doesn’t exist over India. Given the resource-intensive and time-consuming nature of field experiments required for the measurement of soil loss across a vast country, the Revised Universal Soil Loss Equation (RUSLE) was extensively utilized for soil erosion calculations due to its simplicity, streamlined data requirements, and accuracy. This study estimates the yearly potential soil loss throughout India at a spatial resolution of 250 meters and quantifies its variability considering districts, soil texture, soil type, land use and land cover, and basins. The relative importance of individual and combined impact of multiple parameters on quantified soil loss has been assessed using a random forest model. Rainfall erosivity (R-factor) emerges as the most crucial feature in estimating soil erosion in Indian conditions while rainfall intensity, combined with the topographic factor, demonstrated the highest influence on soil erosion in Indian conditions when the combined impact was assessed. Further, we mapped the Sediment Delivery Ratio (SDR) and Specific Sediment Yield (SSY) to assess the actual soil loss reaching downstream of basins across the national boundary. The national mean values for Sediment Delivery Ratio (SDR) and Sediment Yield (SSY) stand at 0.11 and 2.61 tons per hectare per year, respectively. The yearly potential soil loss for India is calculated at 21 tons per hectare per year, and nine out of the twenty districts with the highest susceptibility to soil erosion are in the state of Assam. Finally, a novel impact-based erosion-severity classification system has been introduced which finds that 29.46% of the landmass is prone to minor erosion while 3.17% experiences catastrophic erosion. This is the first comprehensive national-scale assessment of both soil erosion and sediment yield mapping over India, and the consequent classification system will enable the planning and implementation of soil conservation strategies locally as well as nationally.
Curiosity and reward after unsuccessful memory recall
Authors: Brooks Gregory , Kohler Stefan
Published: March 2024

Curiosity is a motivational state characterized by the desire to obtain knowledge. Prior research suggests that metacognitive experiences during unsuccessful memory recall may induce curiosity. Specifically, feeling-of-knowing (FOK) experiences have been associated with increased subsequent information-seeking behaviour for inaccessible information. Here, we further investigated this relationship by focusing on subjective experiences of curiosity and reward. Our paradigm required learning of face-name associations followed by probing of name recall and FOK experiences on unsuccessful trials. Subsequently, participants rated their curiosity (Experiment 1) or made information-seeking choices and rated their satisfaction upon completion (Experiment 2). Results showed, as predicted, that FOK experiences correlate with subjective ratings of curiosity as well as information-seeking choices. Critically, we found they are also positively correlated with satisfaction reported upon exposure to sought information. These correlational findings converge to suggest that unsuccessful memory recall shapes subsequent information seeking behaviour through a combination of metacognitive and reward-based mechanisms.
Dissociative experiences arise from disrupted multi-sensory integration

Dissociation is a transdiagnostic mental health symptom involving a sense of detachment from one’s own body. A coherent percept of our body relies upon the smooth integration of different senses, such as vision and touch, which are processed by the brain at different speeds. In a N=100 non-clinical sample, we used Virtual Reality to investigate sensory-integration by systematically lengthening a delay to an immersive visual feed on a head-mounted display, resulting in visual information being delayed relative to other senses (e.g. touch). Larger delays were associated with self-reported feelings of dis-ownership from the body, and participants with high trait dissociation were more sensitive to delay, suggesting an increased tendency to ‘fraction’ senses. Moreover, individuals with higher dissociation displayed similar cardiac reactivity to both self and other touch. These findings highlight two key mechanisms underlying dissociation; altered sensory-integration and distinct processing of self and other touch.
Using Large Language Models to Augment (Rather Than Replace) Human Feedback in Higher Education Improves Perceived Feedback Quality

Formative feedback on assignments such as essays or theses is deemed necessary for students’ academic development in higher education. However, providing high quality feedback can be time-intensive and challenging, and students frequently report dissatisfaction with feedback quality. Here we explore a possible solution, namely using large language models (LLMs) to augment feedback provided by instructors. One potential obstacle to using LLM-augmented feedback is algorithm aversion, which might lead students to deprecate LLM-augmented feedback. Therefore, we examined students’ perceptions of human versus LLM-augmented feedback. In a pre-registered study, participants (N = 112) evaluated original human-generated versus LLM-augmented feedback on a previous assignment. Our results show evidence against algorithm aversion. Furthermore, participants rated the quality of LLM-augmented feedback substantially higher and strongly preferred it over the human-generated original. Our findings demonstrate the potential of LLMs to solve the persistent problem of low perceived feedback quality in higher education.
How preferences enslave attention: calling into question the endogenous/exogenous distinction from an active inference perspective
Authors: Parvizi-Wayne Darius
Published: March 2024

It is easy to think of attention as a sensory mechanism divorced from the influence of an agent’s preferences and needs. However, according to active inference, such strict divisions cannot be invoked, since all cognitive and behavioural processes can be described as maximising the evidence for an agent’s generative model, which entails preferences that make an entity the thing it is. As such, attention — and perception more broadly — is constrained or enslaved by prior beliefs for which an agent must seek evidence. This paper demonstrates that this imperative is always at play in cognitive systems endowed with attentional schema, and that the preferences in question transcend the contingent, task-relevant goals that bias attention. Rather, attention is powerfully tuned by the most-deep rooted priors the agent possesses, such that, when sensory evidence against these priors is observed and free energy spikes, the agent attentionally prioritises the homeostatic restoration of these preferred states over their shorter-term desires. Thus, at its core, attention is a goal-driven process, which calls into question the putative distinction between endogenous – goal-directed, top-down – attention and exogenous – bottom-up, stimulus-driven, automatic – attention. What emerges in its place is a symbiotic relationship between attention and preferences, whereby the fulfilment of the latter rests on successful application of the former, and the former derives its function from the organismic need to confirm the latter.
