An Evidence-Based Hypothesis: Doctors Do Not Make Decisions Randomly but Based on Individual Patient’s Risk Profiles
Authors: Porzsolt Franz , Weiss Christel , Weiss Manfred
Published: May 2024

According to Sir Archibald Cochrane systematic errors can be avoided in clinical studies if the three dimensions of health care are confirmed: (a) the objective principle of action (the Proof of Principle, PoP) (b) the objective suitability in everyday care (the Real-World Effectiveness, RWE), and (c) the subjectively perceived value (Value). The strategy for confirming these three dimensions is suggested. The method for proving the suitability of health services in everyday care (RWE) is described in six chapters: 1. The basis for the evaluation of health services. 2. The "terminology conflict" used to describe the "natural chaos in everyday care". 3. The proposed solution to prove suitability for everyday use. 4. The method for detecting everyday effects of health care. 5. The importance of emotionally perceived information. 6. Goals that can only be achieved in Pragmatic, not Randomized Trials.If the hypothesis that physicians base their decisions on the risk profile of the individual patient is accepted, medicine can take a significant step forward. This step brings about a change of perspectives. Decisions for (non-experimental) day-to-day care are no longer derived from experiments but from (pragmatic) controlled observations of everyday care.
The Zeroth Law of Science
Authors: Mitteldorf Josh
Published: May 2024

The practice of science is based on the premise that our universe obeys laws. Behavior of identical systems is presumed to be identical, independent of time and spatial variables, independent of the observer. This is not only a fundamental principle that we take for granted, it is also a scientific hypothesis, testable empirically. Evidence for validity of the Zeroth Law of Science is mixed.
Pvt measurements on fluoroform : second and third virial coefficients from 200 [degrees] c to 350 [degrees] c and compressibility factors to 150 atmospheres
Authors:   , Liou Wen-shou
Published: May 2024

The Burnett method was employed to study the volumetric behavior of fluoroform gas from 200 to 350[degrees]C at pressure up to 150 atmospheres. An estimate of the assignable measurement errors indicate the data should be accurate to 5 part in 10,000. A nonlinear regression analysis method was used to evaluate the second and the third virial coefficients of fluoroform gas. This data analysis method considers both the dependent and the independent variables are subject to error and eliminates the need for prior knowledge of the run constant and the apparatus constant to evaluate the second and the third virial coefficients of the gas. The parameters of Benedict- Webb-Rubin equation of state were evaluated by using the experimental Burnett p-v-T measurements. The Benedict- Webb-Rubin equation of state represents the data within the experimental error of the measurements.

Published: May 2024

Objective: To describe the prompt and successful treatment of an extrauterine pregnancy case in a tertiary-level hospital in Indonesia.
Methods: We report a case of prompt and successful management of unruptured tubal pregnancy in the dr. Soetomo General Hospital Surabaya.
Results: A 32-years-old woman presented with lower abdominal pain and vaginal bleeding one days before admission. She was sexually active, used no contraceptives, and had a history of one miscarriage. On examination, she was hemodynamically stable. A bimanual exam revealed cervical motion tenderness and pain. A high human chorionic gonadotropin (hCG) level (1,725 IU/L) and a left-sided mass, highly suspected as an extrauterine gestational sac confirming a 6 week, 1 days age of pregnancy without sign of free fluid in the abdomen nor fetal heart rate on ultrasound, prompted diagnostic laparoscopy. We found a tubal pregnancy located on the ampullae of the left fallopian tube with minimal hemoperitoneum (50 ml). A chromopertubation test was done to ensure a patent right fallopian tube, so we did a salpingectomy. The patient recovered well and was discharged home on day 2 post-procedure.
Conclusion: Early diagnosis is vital and feasible to prevent morbidity and mortality in women with ectopic pregnancy. All sexually active women complaining painful abdomen or vaginal bleeding must be examined for an ectopic pregnancy to enable early diagnosis and prompt treatment. A laparoscopic surgery done by a trained individual provided a safe and minimally invasive intervention to this case.

Published: May 2024

Breeding propensity, defined as the probability that a sexually mature adult will breed in a given year, is an important determinant of annual productivity. It is also one of the least known demographic parameters in vertebrates. We studied the relationship between breeding propensity and conditions on spring staging areas (a spring conservation hunt) and the breeding grounds (spring snow cover) in Greater Snow Geese (Chen caerulescens atlantica), a long distance migrant that breeds in the High Arctic. We combined information from mark–recapture, telemetry, and nest survey data to estimate breeding propensity over a 7–year period. True temporal variation in breeding propensity was considerable (mean: 0.574 [95 % CI considering only process variation: 0.13 to 1.0]). Spring snow cover was negatively related to breeding propensity (bsnow=-2.05 ± 0.96 SE) and tended to be reduced in years with a spring hunt (b = -0.78 ± 0.35). Nest densities on the breeding colony and fall ratios of young:adults were good indices of annual variation in breeding propensity, with nest densities being slightly more precise. These results suggest that conditions encountered during the pre-breeding period can have a significant impact on productivity of Arctic-nesting birds
Evaluation of ultrastructure and random effects band recovery models for estimating relationships between survival and harvest rates in exploited populations
Authors:   U.S. Geological Survey, Iowa State Univ., Ames, USA, Otis D. L. , White G. C. ,   Colorado State Univ., Fort Collins, USA
Published: May 2024

Increased population survival rate after an episode of seasonal exploitation is considered a type of compensatory population response. Lack of an increase is interpreted as evidence that exploitation results in added annual mortality in the population. Despite its importance to management of exploited species, there are limited statistical techniques for comparing relative support for these two alternative models. For exploited bird species, the most common technique is to use a fixed effect, deterministic ultrastructure model incorporated into band recovery models to estimate the relationship between harvest and survival rate. We present a new likelihood-based technique within a framework that assumes that survival and harvest are random effects that covary through time. We conducted a Monte Carlo simulation study under this framework to evaluate the performance of these two techniques. The ultrastructure models performed poorly in all simulated scenarios, due mainly to pathological distributional properties. The random effects estimators and their associated estimators of precision had relatively small negative bias under most scenarios, and profile likelihood intervals achieved nominal coverage. We suggest that the random effects estimation method approach has many advantages compared to the ultrastructure models, and that evaluation of robustness and generalization to more complex population structures are topics for additional research.
Ecosystem management via interacting models of political and ecological processes
Authors:   School of Business Administration, Univ. of Wisconsin at Milwaukee, USA, Haas T. C.
Published: May 2024

The decision to implement environmental protection options is a political one. Political realities may cause a country to not heed the most persuasive scientific analysis of an ecosystem’s future health. A predictive understanding of the political processes that result in ecosystem management decisions may help guide ecosystem management policymaking. To this end, this article develops a stochastic, temporal model of how political processes influence and are influenced by ecosystem processes. This model is realized in a system of interacting influence diagrams that model the decision making of a country’s political bodies. These decisions interact with a model of the ecosystem enclosed by the country. As an example, a model for Cheetah (Acinonyx jubatus) management in Kenya is constructed and fitted to decision and ecological data.
Application of integrated Bayesian modeling and Markov chain Monte Carlo methods to the conservation of a harvested species
Authors:   Univ. of Georgia, Athens, USA, Fonnesbeck C. J. , Conroy M. J. ,   Univ. of Georgia, Athens, USA
Published: May 2024

When endeavoring to make informed decisions, conservation biologists must frequently contend with disparate sources of data and competing hypotheses about the likely impacts of proposed decisions on the resource status. Frequently, statistical analyses, modeling (e.g., for population projection) and optimization or simulation are conducted as separate exercises. For example, a population model might be constructed, whose parameters are then estimated from data (e.g., ringing studies, population surveys). This model might then be used to predict future population states, from current population estimates, under a particular management regime. Finally, the parameterized model might also be used to evaluate alternative candidate management decisions, via simulation, optimization, or both. This approach, while effective, does not take full advantage of the integration of data and model components for prediction and updating; we propose a hierarchical Bayesian context for this integration. In the case of American black ducks (Anas rubripes), managers are simultaneously faced with trying to extract a sustainable harvest from the species, while maintaining individual stocks above acceptable thresholds. The problem is complicated by spatial heterogeneity in the growth rates and carrying capacity of black ducks stocks, movement between stocks, regional differences in the intensity of harvest pressure, and heterogeneity in the degree of competition from a close congener, mallards (Anas platyrynchos) among stocks. We have constructed a population life cycle model that takes these components into account and simultaneously performs parameter estimation and population prediction in a Bayesian framework. Ringing data are used to develop posterior predictive distributions for harvest mortality rates, given as input decisions about harvest regulations. Population surveys of black ducks and mallards are used to obtain stock-specific estimates of population size for both species, for inputs into the population life-cycle model. These estimates are combined with the posterior distributions for harvest mortality, to obtain posterior predictive distributions of future population status for candidate sets of regional harvest regulations, under alternative biological hypotheses for black duck population dynamics. These distributions might then be used for both the exploration of optimal harvest policies and for sequential updating of model posteriors, via comparison of predictive distributions to future survey estimates of stock-specific abundance. Our approach illustrates advantages of MCMC for integrating disparate data sources into a common predictive framework, for use in conservation decision making.

The quantitative study of marked individuals relies mainly on the use of meaningful biological models. Classical inference is then conducted based on the model likelihood, parameterized by parameters such as survival, recovery, transition and recapture probabilities. In classical statistics, we seek parameter estimates by maximising the likelihood. However, models are often overparameterized and, as a consequence, some parameters cannot be estimated separately. Identifying how many and which (functions of) parameters are estimable is thus crucial not only for proper model selection based upon likelihood ratio tests or information criteria but also for the interpretation of the estimates obtained. In this paper, we provide the reader with a description of the tools available to check for parameter redundancy. We aim to assist people in choosing the most appropriate method to solve their own specific problems.

La sociología desarmada. Crisis y renovación de la disciplina tras el golpe de Estado
Authors: Iglesias Vázquez Mónica
Published: May 2024

En este artículo examino el proceso de transformación que experimentó la sociología a raíz del golpe de Estado del 11 de septiembre de 1973. A partir del análisis de un conjunto de textos, en que los propios protagonistas reflexionaron sobre el impacto del golpe y de la dictadura militar, reconstruyo, desde una perspectiva crítica, las transformaciones que tuvieron lugar en el campo académico, así como el proceso de renovación de las ciencias sociales y, particularmente, de la sociología, atendiendo a tres dimensiones fundamentales: el rol del sociólogo, el papel de la teoría y el carácter performativo de la ciencia social. Muestro cómo la renovación sociológica es, en primer lugar, un producto del quiebre emotivo que generó el golpe de Estado.

Authors: Vash Yurii , Rol Mariana , Chyzhmar Mykola
Published: May 2024

This study presents a significant enhancement to the Dynamic Time Warping (DTW) algorithm for real-time applications like speech recognition. Through integration of SIMD (Single Instruction Multiple Data) instructions to distance function, the research demonstrates how SSE accelerates DTW, markedly reducing computation time. The paper not only explores the theoretical aspects of DTW and this optimization but also provides empirical evidence of its effectiveness. Diverse dataset of 18 voice command classes was assembled, recorded in controlled settings to ensure audio quality. The audio signal of each speech sample was segmented into frames for detailed analysis of temporal dynamics. DTW search was performed on features set based on Mel Frequency Cepstral Coefficients (MFCC) and Linear Predictive Coding (LPC), combined with delta features. A comprehensive set of 27 features was extracted from each frame to capture critical speech characteristics. The core of the study involved applying traditional DTW as a baseline for performance comparison with the SSE-optimized DTW. The evaluation, focusing on computational time, included measurements like minimum, maximum, average, and total computation times for both standard and SSE-optimized implementations. Experimental results, conducted on datasets ranging from 5 to 60 WAV files per class, revealed that the SSE-optimized DTW significantly outperformed the standard implementation across all dataset sizes. Particularly noteworthy was the consistent speed of the SSE-optimized Manhattan and Euclidean distance functions, which is crucial for real-time applications. The SSE-optimized DTW maintained a low average time, demonstrating remarkable stability and efficiency, especially with larger datasets. The study illustrates the potential of SSE optimizations in speech recognition, emphasizing the SSE-optimized DTW's capability to efficiently process large datasets.
Solutions of the theory of thermoelasticity and thermal conductivity in the cylindrical coordinate system for axisymmetric temperature
Authors: Revenko Victor
Published: May 2024

The paper uses the system of Navier equations in the stationary case. A cylindrical coordinate system is considered, when the temperature does not depend on the angular variable. A partial solution of the system of Navier equations, which does not contain elastic displacements, is called a purely temperature solution. It was established that for purely temperature solutions the sum of normal stresses is zero and the volume deformation is equal T e  = 3 . An analytical expression of purely temperature displacements and stresses in the cylindrical coordinate system in the axisymmetric case was found. The solution of the boundary value problem of thermal conductivity, when the cylinder is heated on one end, cooled by liquid on the other with known heat losses on the side surface, is proposed. The solution of the boundary value problem of thermal conductivity for such a cylinder is given in the form of the sum of the basic temperature, which describes the heat balance, and the perturbed temperature. The basic temperature has a polynomial form and integrally satisfies the boundary conditions. The perturbed temperature has an exponential decrease with distance from the heated end and does not carry out integral heat transfer. The found dependencies were used and a new solution to the heat conduction equation was written in a cylindrical coordinate system. Simple formulas for expressing temperature changes have been obtained. A new temperature solution to the system of thermoelasticity equations in a cylindrical coordinate system has been written, when the temperature does not depend on the angular variable.

Authors: Kravets Oleh , Shynkaryk Mariia , Kravets Viktor
Published: May 2024

Sewage from milk processing enterprises remains a factor of environmental pollution. This is caused by a high concentration of organic pollutants contained in a dispersed and dissolved state, among which protein predominates. An effective way to increase the environmental friendliness of dairy enterprises is to minimize emissions of pollutants. In particular, this applies to dairies, the main products of which are protein products - cheese and casein, and the main pollutant - whey. This could be achieved through complete processing of whey. The article considers the possibility of reducing the polluting effect of wastewater from milk processing enterprises by separating dispersed protein from milk whey. The results of the study of the content and granulometric composition of dispersed whey protein are presented. The design of the filter with a self-cleaning filter element developed by the authors is presented, which allows for a continuous process of serum purification with a consistently high degree of separation.

Published: May 2024

Gas analysis devices are measuring instruments and require periodic confirmation of their metrological parameters. This paper deals with methods of metrological support of measurements of absorption remote devices (with open cuvette). The design of the device where the operating and calibration cuvettes (with calibration gas mixture) are alternately (if necessary) placed on the optical path of the device, with the same optical elements. is proposed. This method of calibration and verification allows you to do without the use of CGM, which greatly simplifies calibration and verification of the gas analyzer at the workplace. In addition, the method reduces the calibration and verification error, since in the calibration mode the light flux passes along the same optical path as in the measurement mode, while the light flux and the degree of contamination of the optical elements by selective and non-selective components of the analyzed mixture remain unchanged.

Authors: Sangadji Ningsi Lick , Wijaya Candra , Sangian Hanny Frans , Widjaja Arief
Published: May 2024

To enhance the hydrolysis to produce fermentable sugar, oil palm empty fruit bunch (OPEFB) has undergone ultrasonication pretreatment prior to subjection to subcritical water hydrolysis. This work aims to optimize the effect of temperature, reaction time, and the concentration of sodium dodecyl sulfate (SDS) as the surfactant, with the primary aim of maximizing sugar production in the subcritical water hydrolysis process applied to oil palm empty fruit bunch (OPEFB). The pretreatment process conditions were optimized using response surface methodology of the central composite design (RSM–CCD). The experimental design includes three factors and levels, with a range of 180–220 °C temperature (X1), 60–80 minutes process time (X2), and 1–5% w/w SDS concentration (X3), an α value of 1.68, and reducing sugar concentration (g/L) as response (Y1). The optimum condition for subcritical water hydrolysis of OPEFB was obtained at 208 °C, 78 minutes, and 2.6% w/w SDS concentration with an expected yield of 6.09 g/L. As a result, reducing sugar produced by enzymatic hydrolysis increased by 324.7% compared to raw OPEFB, with sugar yield of 45.64% after 36 hours. Along these, changes in crystallinity, chemical composition, lignocellulosic functional groups, and morphology were analyzed to determine the impact of the pre-treatment on OPEFB.

The present study attempted an empirical investigation to explore the loneliness and depression of Chittagong university students. A total of 100 purposively selected and readily available respondents constituted the sample of the study. An adapted Bengali version of Revised UCLA Loneliness Scale (Parveen 2007) and Depression Scale developed by Rahman and Uddin (2005) were used. Data were analyzed by Pearson Product Moment Correlation and two-way analysis of variance (ANOVA). The findings of the present study showed that there is no significant difference between male and female students; and residential and non-residential students in loneliness. No significant interaction effect was found between gender and residence in loneliness. There is no significant difference between the males and females, however residential students have significantly more depression (F =14.06, df =1, p<0.01) than non residential students. No significant interaction effect was found between gender and residence in depression. Results also showed that loneliness is positively correlated (r=0.29, p<0.01) with the presence of depression among the respondents of this study.

Artificial neural networks (ANN) are very useful for predicting biological activities in QSAR studies. ANNs allow the study of complex and nonlinear SAR. We use ANN and MLR methods to generate QSAR models for Calcium Channel Blockers activity of a series of 1,4-dihydropyridines. Molecular descriptors were calculated by using DFT method at the B3LYP/6-31G+ (d, p) level. Statistical analyzes show that the predicted values of the activities are in excellent agreement with the experimental results. Molecular docking studies have been performed, in order to re-estimate the activity of molecules as CCBs by analyzing their binding energies and mutual interaction types.

Background: Deficiency of insulin signaling in type 2 diabetes results from insulin resistance or defective insulin secretion and induce hyperglycemia. Diabetes is a global threat that continues to increase day by day at a very high rate in both developing and developed countries. Glucokinase activators (GKA) can be a novel target used for better management of type 2 diabetes. Recently novel GKA Dorzagliatin received market approval by Japan FDA for treatment of type 2 diabetes.
Objective: The purpose of designing glucokinase activators was to develop novel therapeutic molecules with minimum side effects.
Methods: A docking study was conducted using AutoDock Vina 1.5.6, and the structures were created using ChemBiodraw Ultra. The Swiss ADME algorithm was used for online log p prediction.
Results: Among all the molecules designed, AM35 had the highest binding affinity to GK receptors. For good absorption and elimination, Log P values range from 2-3.08, indicating good lipophilic properties.
Conclusion: The new lead molecules were designed as glucokinase activators, which had a better pharmacokinetic profile and higher binding affinity.

Published: May 2024

Diabetes mellitus and its complications are among the primary causes of death and disability. Retinopathy, cardiovascular disease, and neuropathy develop progressively with prolonged hyperglycemia. Finding an effective and secure drug with fewer side effects to handle diabetes-related complications is necessary. Numerous scientists are launching new initiatives to investigate plant sources, which are known to contain a vast array of active agents. An edible marine algae, Caulerpa racemosa, was reported to have bioactivities including antidiabetes, anti-inflammatory and neuroprotective. Consequently, the current study was conducted to investigate bisindoles from Caulerpa racemosa using in silico method. Five bisindoles such as caulerpin, caulersin, racemosin A, racemosin B and racemosin C were selected to be anticipated their interaction binding mode and interaction energies toward protein targets associated with NF−κB such as TAK1 (7NTI), NIK (4IDV) and MMP−9 (4H3X) using AutoDock Vina integrated with Chimera, while their predicted ADMET were proceeded using web tool pkCSM. The result indicated that caulerpin
all the compounds were predicted to interact molecularly with amino acids surrounding the binding site of protein targets. indicating the most favorable interaction with targets Predicted pharmakokinetics showed that most of the compounds meet the minimum standard parameters in ADMET properties. The findings suggested that bisindoles contained in Caulerpa racemosa might potentially to be used in treatment of diabetes-related complications
WEAK FAMILY TIES AS ONE OF THE DETERMINANTS OF REPEATED CRIMES COMMITTED BY CONVICTS SERVING SENTENCES WITHOUT ISOLATION FROM SOCIETY
Authors: Dorozhinskij Artur
Published: May 2024

The article examines such negative trends in modern society as weak family ties, the withering of traditional family values, and the decline in the role of marriage, which act as determinants of repeated crimes committed by convicts serving sentences without isolation from society. A number of preventive measures of different levels are proposed. There are general social preventive measures aimed at solving the problems of the institution of the family, as well as special criminological measures to combat the causes of repeated crimes among convicts of the studied category who have problems in family relations. It is concluded that strong family ties can have a positive preventive effect on repeat crimes among convicts, reducing their level.
Pennella balaenoptera actively select injured cetacean skin as attachment sites, making them potentially useful forensic tags
Authors: Chaieb O , Ten S , Aznar FJ
Published: May 2024

Cetaceans harbor multiple epibionts on their external surface, and these attach to particular microhabitats. Understanding what drives the selection of attachment sites is relevant for refining the use of epibionts as indicators of their hosts. We report on about 100 females of the mesoparasitic copepod Pennella balaenoptera attached to a dead Cuvier’s beaked whale Ziphius cavirostris stranded in Tunisia (western Mediterranean); the first report of P. balaenoptera in this country. The copepods were exclusively attached to numerous incisive, likely anthropogenic, wounds found on the host’s skin. This finding suggests that newly recruited females may actively seek skin areas where physical penetration is facilitated; a factor that may help explain patterns of microhabitat selection by Pennella spp., and perhaps other pennellids, on their hosts. The estimated age of parasitization by P. balaenoptera (supported by age estimations of the co-occurring epibiotic barnacle Conchoderma virgatum) also suggests that the cetacean host likely survived these injuries, at least initially, and the presumed cause of death was starvation due to entanglement in a fishing net.
