The Application of Artificial Digital Models in X-Ray Computed Tomography (CT) of the Core in Solving the Problem of Binarization of the Void Space of Reservoir Rocks
Authors: Melkishev O. A. , Savitsky Y. V. , Galkin S. V. 
Published: January 2025

The X-ray tomography method has several advantages, including its non-destructiveness and the ability to visualize the rock skeleton and pore space in three dimensions. However, one of the main challenges of this method is the limited resolution when studying core samples that are 30 millimeters in diameter, which is typical for petrophysical analysis. In these samples, a significant portion of pores have dimensions smaller than the resolution capabilities of most X-ray tomographic systems, making it impossible to accurately determine the boundary between the pore and skeleton structures in tomograms, nor visualize the entire pore volume.To verify this hypothesis, tomograms from real oil and gas samples were analyzed. The resulting histograms of X-ray densities revealed that it is not possible to directly measure the threshold value of X-ray density that defines the “skeleton-pore” boundary. In order to solve the problem of estimating boundary values, a technique is proposed in this work that suggests using artificial digital models – phantoms. This approach has been previously used mainly in computer modeling, but it has not been used much in petroleum geology. The main advantage of using phantoms is complete control over the set pore space parameters and X-ray density of the skeleton, which cannot be achieved on real samples.A computational experiment was conducted in the work, where 124 core phantoms with specific porosity characteristics were generated using numerical modeling. These phantoms were then converted into tomograms, allowing us to determine statistical characteristics of the values for X-ray densities of the samples at the reconstruction stage.Based on the statistical analysis of the X-ray density distribution in the sample, we determined the boundary values that are most suitable for reliable void space detection. Using regression and correlation methods, we developed a model to estimate the optimal boundary value for X-ray density in void space allocation.We proposed an algorithm for determining and applying this value in the analysis of core X-ray CT data.This model was tested on real samples that were not used in the development of the forecast model. The use of the proposed model for predicting boundary values on obtained tomograms demonstrated a high degree of consistency with actual data.
Organic Geochemistry of Bituminous Shales in the Kashpirskoe field (Samara region)
Authors: Timoshina I. D. , Ivanova E. N. 
Published: January 2025

The studied Upper Jurassic and Lower Cretaceous bituminous shales of the Kashpirskoe field contain organic matter (OM) terrestrial in carbon isotopic composition (δ13C > –24‰) and marine in pyrolytic characteristics (HI > 500 mg HC/g TOC). Shales contain autochthonous bitumens that are marine (Pr/Ph ≤ 0.5, Ph/nC18> 1, distribution of biosteranes with C29/C27 ≤ 1.5, presence of long-chain alkyl naphthalenes – indicator of marine algae Gloeocapsomorpha prisca, “V-shaped” distribution of methyldibenzothiophenes). At the same time, a number of parameters correspond to the terrestrial OM (in n-alkanes nC27/nC17 >>1, Pwax (0.6–0.7) > Paq(0.4–0.5), the indicator of coniferous plants reten is marked in the aromatic fraction), which indicates the proximity of land. Isorenieratene derivatives, biomarkers of specific Chlorobiaceae bacteria, were found in the samples; therefore, despite the probable proximity of land, anoxia occurred in the photic layer of the sedimentation basin. The presence of diasterenes indicates diagenetic transformations also under conditions of anoxic sediment. According to the results of pyrolysis, the OM is catagenetically weakly mature (very low Tmax), which is confirmed by the composition of the bitumen (CPI ≥ 1.7 in n-alkanes, high Pr/nC17 and Ph/nC18 ratios, absence of isoand diasteranes, presence of biosteranes and sterenes, low concentrations or absence of typical terpanes, presence of biohopanes and hopenes, low the ratio of homohopanes C3122S/(22S+22R) << 0.5, low ratios of MDR (0.5–1.0) and MPI-1 (0.4–0.8), mostly absent (not yet formed) monoand triaromatic steroids).The Lower Cretaceous shales from the boundary interval between the Volgian and Ryazan stages, not characterized by fauna, are more enriched in terrestrial components compared to the Upper Jurassic oil shales from the Dorsoplanites panderi ammonite zone. The peculiarities in the characteristics of the studied shales are associated with the genetic specificity of the OM, with anoxia in water and sediment with the accumulation of OM, and with its weak catagenetic maturity at fairly high concentrations.
Clinical Indicators for Evaluating Japanese Public Hospital Performance: Changes after the Epidemic Phase of Novel Coronavirus Infection
Authors: Moteki Yasutoshi 
Published: January 2025

Abstract

Aim
This study investigates the adoption and implementation of clinical indicators in Japanese public hospitals, focusing on changes since the coronavirus disease 2019 pandemic and utilizing Donabedian's triadic model (structure, process, outcome).
Subject and Methods:
A nationwide postal survey was conducted targeting 848 municipal hospitals with ≥ 20 beds in Japan. The survey explored clinical indicator usage, categorized by Donabedian’s framework. Hospitals were classified based on size to evaluate disparities in indicator adoption. Data were analyzed to compare findings from the current 2024 survey with a similar 2016 survey.
Results
The response rate was 15.7%, with 130 valid responses. Clinical indicator adoption increased from 42.4% (2016) to 58.5% (2024). Large hospitals were more likely to implement clinical indicators (88.1%) than small and medium hospitals (27.0%). Frequently used indicators included average hospitalization duration, bed utilization rates, and clinical pathway coverage. Each structural indicator remained underutilized, with < 15% of hospitals reporting their use.
Conclusion
The findings highlight progress in clinical indicator adoption, particularly in large hospitals. However, significant disparities persist between hospital sizes. As the pandemic subsides, it remains essential to continue improving hospital management practices, including clinical indicator use, in preparation for future infectious disease outbreaks. The three-way model classification for medical evaluation is renowned, but the percentage use of structural indicators has not exceeded 15%, and the implementation status is not as advanced as that of process and outcome indicators. Our results are significant as they verify the explanatory power of the three-way model for medical care based on Japanese data.

ABSTRACT

This study describes the preparation of clay/polymer composites using Bijoypur clay (kaolinite) and copolymer poly(hydroxyethylacrylamide-co-3-methacryloxypropyltrimethoxysilane) (poly(HEAA-co-MAPTS)) for the removal of organic dyes from industrial wastewater. The copolymer was prepared by free-radical polymerization of hydroxyethylacrylamide (HEAA) and 3-methacryloxypropyltrimethoxysilane (MAPTS). The clay was activated and purified followed by modification with dodecylamine. FT-IR analysis confirmed successful modification of clay and incorporation of polymer and organoclay in the composites. TG analysis showed that the composite exhibited better thermal properties with increasing polymer percentage. X-ray diffraction analysis revealed that the crystalline size of the composites increased from 23.79 to 60.43 nm with the increasing percentage (1–4%) of polymer. SEM analysis of the composite with higher polymer percentage showed uniform porous structure. Adsorption study was carried out using methylene blue (MB) and acid black-172 (AB) dyes. The composites with higher polymer concentration showed better adsorption capacity for both MB (5.288 mg/g) and AB (6.696 mg/g) dyes in aqueous solution, at initial concentration of 25 ppm, 50 mg of dose, and pH of 10.1 for MB and 4 for AB. The developed composites exhibited adsorption capability for both cationic and anionic dyes which gives a scope to their universal application in dye removal from industrial wastewater.

The governor general of the East India Company, Lord Cornwallis introduced the permanent settlement act in 1793 in Eastern India. This law expanded to South India later on after the 1800s. The law gave superior landholding rights to a group called Zamindars, a diverse group that can be broadly categorized as rural elites. These land holding rights included a plot with tangible boundaries and tax collection power on behalf of the government. This deed operated on the basis of heritable ownership and would be saleable and mortgageable. However, if a Zamindar failed to pay the revenue before sunset of the due date, the government seized the land and sold it to the highest bidder. This act had both short- and long-term socio-political impacts on its operations. This research looks into the origins of the Permanent Settlement Act of 1793 in a more holistic manner. Most research focuses on either intellectual or political motivations behind the introduction of the Act. This research will try to synthesize the factors and consider the ways they both influenced each other. It will also look into its initial operations and reactions towards it. This will also further explain the Act’s origins by understanding what changed in the first place, why and how so.

ChemModLab, written by the ECCR @ NCSU consortium under NIH support, is a toolbox for fitting and assessing quantitative structure-activity relationships (QSARs). Its elements are: a cheminformatic front end used to supply molecular descriptors for use in modeling; a set of methods for fitting models; and methods for validating the resulting model. Compounds may be input as structures from which standard descriptors will be calculated using the freely available cheminformatic front end PowerMV; PowerMV also supports compound visualization. In addition, the user can directly input their own choices of descriptors, so the capability for comparing descriptors is effectively unlimited. The statistical methodologies comprise a comprehensive collection of approaches whose validity and utility have been accepted by experts in the fields. As far as possible, these tools are implemented in open-source software linked into the flexible R platform, giving the user the capability of applying many different QSAR modeling methods in a seamless way. As promising new QSAR methodologies emerge from the statistical and data-mining communities, they will be incorporated in the laboratory. The web site also incorporates links to public-domain data sets that can be used as test cases for proposed new modeling methods. The capabilities of ChemModLab are illustrated using a variety of biological responses, with different modeling methodologies being applied to each. These show clear differences in quality of the fitted QSAR model, and in computational requirements. The laboratory is web-based, and use is free. Researchers with new assay data, a new descriptor set, or a new modeling method may readily build QSAR models and benchmark their results against other findings. Users may also examine the diversity of the molecules identified by a QSAR model. Moreover, users have the choice of placing their data sets in a public area to facilitate communication with other researchers; or can keep them hidden to preserve confidentiality.

Hunting for Insect-Specific Protein Domains
Authors: Matute Daniel R. , Barreto-Hernandez Emiliano , Falquet Laurent 
Published: January 2025

Automatically finding new protein domains is a challenge when using the complete collection of known proteins (i.e., UniProt). By limiting the taxonomic range to class insecta, including two full proteomes (A. gambiae and D. melanogaster), we reduced the size of the search space in the hope of finding taxon-specific domains. The MKDOM2 program (http://prodes.toulouse.inra.fr/prodom/xdom/mkdom2.html) was used to cluster the insect proteins into potential domains that were analyzed manually in a second step. We analyzed 219 potential domains, of which 2 were insect-specific. We show that it is possible to find new domains or to extend known domains using a semi-automated method; however the goal to detect class-specific domains was only partially achieved in the sense that the new domains we found were not all insect-specific domains. The files used as input and the resulting output files, as well as extensive descriptions of the domains, are available as supplementary data from http://bioinf.ibun.unal.edu.co/insecta/.

Genomic copy number change is one of the important phenomenon observed in cancer and other genetic disorders. Recently oligonucleotide microarrays have been used to analyze changes in the copy number. Although high density microarrays provide genome wide useful data on copy number, they are often associated with substantial amount of experimental noise that could affect the performance of the analyses. We used the high density oligonucleotide genotyping microarrays in our experiments that uses redundant probe tiling approach for individual SNPs. We found that the noise in the genotyping microarray data is associated with several experimental steps during target preparation and devised an algorithm that takes into account those experimental parameters. Additionally, defective probes that do not hybridize well to the target and therefore could not be modified inherently were detected and omitted automatically by using the algorithm. When we applied the algorithm to actual datasets, we could reduce the noise substantially without compressing the dynamic range. Additionally, combinatorial use of our noise reduction algorithm and conventional breakpoint detection algorithm successfully detected a microamplification of c-myc which was overlooked in the raw data. The algorithm described here is freely available with the software upon request to all non-profit researchers.

Published: January 2025

Ab initio coding potential prediction in a bacterial genome is an important step in determining an organism's transcriptional regulatory function. Extensive studies of genes structure have been carried out in a few species such as. Escherichia coli, fewer resources exist in newly sequenced genomes like Wolbachia. A model of gene prediction trained on one species may not reflect the properties of other, distantly related prokaryotic organisms. These issues were encountered in the course of predicting genes in the genome of Wolbachia, very important gramnegative bacteria that form intracellular inherited infections in many invertebrates. We describe a coding potential predictor based on artificial neural networks and we compare its performance by using different architectures, learning algorithms and parameters. We rely on a dataset of positive samples constructed from coding sequences and on a negative dataset consisted of all the intergenic regions that were not located between the genes of an operon. Both datasets, positive and negative, were output as fasta formatted files and were used for neural network training. The fast, adaptive, batch learning algorithm Resilient propagation, exhibits the best overall performance on a 64input-10hidden-1output nodes multi-layer perceptron neural network.
Investigation of electric double layer effects at Li3PO4 Li+ solid electrolyte thin film interfaces using a field-effect transistor with Al-doped SiC (0001) single crystal

Published: January 2025

Abstract
We developed a Li+ electrolyte-gated electric double-layer transistor (EDLT) using Al-doped SiC (0001) single crystal as the channel material. Thanks to the high tolerance of SiC single crystal to plasma irradiation, the Al-doped SiC EDLT was successfully fabricated with RF-sputtered Li3PO4 Li+ solid electrolyte thin film, which was previously difficult due to plasma-induced damage to the semiconductor channel. The EDLT operation of the device was confirmed by observing a 75% resistance change in the transfer characteristics. Hall measurements were employed to evaluate carrier density changes and directly investigate the behavior of the EDL at the interface. The calculated capacitance revealed contributions from both the EDL capacitance and depletion layer capacitance, indicating that the depletion layer formed on the SiC channel surface prevented accurate evaluation of EDL capacitance. For accurate EDL capacitance measurement, generating an accumulation layer on the surface of the semiconductor channel is found to be essential.

ساعدت فترة الانتقال السياسي في الدولة الإسلامية من الأمويين إلى العباسيين الإمام جعفر الصادق عليه السلام على نشر علوم أهل البيت سلام الله عليهم بحرية واطمئنان وكانت الحقبة الزمنية التي عاشها الأمام الصادق تمثل جانب النضج الفكري والسياسي وكان قد عاصر تيارات فكرية مختلفة وأراء ابتعدت عن مبادئ الإسلام وأحكامه، وقد تصدى لها بالقوة الفكرية، وأبطل دعاتها وفند اضاليلها فيقول الشيخ محمد أبو زهرة:(إن الأمام الصادق وقف في وجه أولئك الذين كانوا ينحرفون في اعتقادهم أو يهاجمون الاعتقاد الصحيح) (1) كالزنادقة والملحدين والغلاة والمجسمة والقدرية والجبرية والمرجئة وغيرها وأراد عليه السلام تثبيت الفكر والأمامي عن طريق الأئمة سلام الله عليهم، وفق التسلسل المعروف بالإمامة وبذلك دحض جميع الآراء المتفرعة من التسلسل وتصدى للفرق المتشعبة عن الأمامية كالكيسانية والزيدية والواقفةوالناووسية وغيرها، وكانت مدرسته في المدينة المنورة والكوفة من أوسع المدارس الفكرية في العالم الإسلامي، وكانت هاتان المدرستان ملتقى الفقهاء والمفسرين والمحدثين، ويقول الأستاذ احمد أمين (أن الأمام الصادق أوسع الناس علما واطلاعا وأقواله تدل على حكمته، وبعد نظرة وسعة علمه)(2) وقد قصد الأمام الصادق عليه السلام مدينتي الحيرة والكوفة في عهدي السفاح والمنصور، واستدعاه أبو جعفر المنصور إلى بغداد عدة مرات، وفــــــــــــــــــي أثنـــــــاء وجوده في العراق زار مرقدي الإمامين علي والحسين عليهما السلام، وتتلمذ عليه جمع من علماء الكوفة، وعند عودته إلــى المدينة بقي الكوفيون علــى صلة به، ويقـول يحيى بن عبدا لله بن الحســن: (سمعت الصادق يقول وعنده أناس من أهل الكوفة)(3) وروى إسماعيل بن أبي الازدي- وهو من الكوفيين- عن الأمام الصادق عليه السلام كتاب (القضايا) وسمع منه مقرئ القران الكريم في مسجد الكوفة عبد الله بن أبي يعفور(4) وبقي اثر الأمام الصادق عليه السلام في مدينة الكوفة بعد وفاته عام 148 هـ فكان العلماء يتناقلون آراءه جيل بعد جيل، فيقول الحسن بن علي بن زياد الوشــاء البجلي:(أدركت في المسجد تسعمائة شيخ كل يقول: حدثني جعفر بن محمد عليه السلام) (5).
