Методом горіння одержано легований Mn4+ α-Al2O3 з розміром частинок 70–600 нм. На підставі результатів люмінесцентних вимірювань в рамках наближення чисто електронних переходів розраховано силу кристалічного поля (Dq) та параметри Рака (B, C) для Mn4+ в α-Al2O3. Одержані значення Dq (1898 см-1) та нефелауксетичного параметра β1 (0.95) для іонів Mn4+ в α-Al2O3 узгоджуються зі значеннями цих параметрів для Mn4+ в інших оксидних сполуках. Зокрема, величина Dq/B = 2.77 вказує, що іони Mn4+ займають в ґратці α-Al2O3 октаедричні позиції Al з великою силою кристалічного поля. Проведено порівняння з літературними даними для іонів Cr3+ в α-Al2O3. Одержано композити загальної формули α-Al2O3:Mn4+, Mg2+/Gd3Al5O12 : Ce3+. Показано, що ці матеріали демонструють інтенсивне широкосмугове випромінювання з максимумами при ~585 і 678 нм. Широка смуга з максимумом при 585 нм зумовлена переходами 5d→4f іонів Ce3+ в Gd3Al5O12, тоді як смуга при 678 нм зумовлена переходами 2Eg→4A2g Mn4+ в α-Al2O3. Колір випромінювання змінюється від жовтого до насичено-червоного із збільшенням вмісту α-Al2O3:Mn4+,Mg2+, а квантова ефективність люмінесценції композитів досягає 0.60.

Композиції рослинних жирних кислот мають різну структуру та склад. Жодна з цих олій не відповідає рекомендаціям щодо співвідношення НЖК : МНЖК : ПНЖК (1 : 1.5 : 1). Метою нашого дослідження є створення купажів олій з місцевої сировини для досягнення оптимального жирнокислотного складу поліненасичених жирних кислот (ПНЖК) омега 6 і омега 3 та співвідношення СЖК : МНЖК : ПНЖК. Для дослідження були обрані олії насіння шипшини (Rosa Canina), льону (Linum usitatissium), волоського горіха (Juglans nigra), сої (Glycine max), ріпаку (Brassica napus) та рисових висівок (Oryza sativa). Лляна олія була змішана з соєвою та ріпаковою оліями в пропорціях 25 : 75, 35 : 65, 45 : 55 (v/v) відповідно. Співвідношення жирних кислот омега 6 : омега 3 в олії льону, ріпаку та шипшини становило 0.28, 1.6 та 1.76 відповідно, що відповідає оптимальному співвідношенню жирних кислот омега 6 до омега 3. Всі олійні суміші відповідали рекомендованим діапазонам співвідношення омега 6 : омега 3 жирних кислот. Однак співвідношення ПНЖК : МНЖК : ПНЖК у суміші льону та соєвої олії становило 1 : 1.99 : 5.32, 1 : 1.94 : 5.3, 1 : 1.9 : 5.38, а у суміші льону та ріпакової олії – 1 : 3.98 : 7.22, 1 : 4.74 : 6.43, 1 : 5.03 : 6.11 відповідно. Ці дослідження показують, що змішування олій є цікавим та економічно вигідним методом покращення поживної цінності різних видів олії.

AbstractIn this work, the optimal design of a mortar based on alkali-activated material technology is presented. Ferronickel slag, a byproduct of the ferronickel alloy industry, was used both as a binder component (in a finely ground form) and as fine aggregate in alignment with a circular economy approach. The proportions of binder, fine aggregate, and water were optimized using Design of Experiment Design of Mixtures. The performance indicators evaluated were flow, flexural and compressive strength both before and after high-temperature exposure, mass loss, and thermal shrinkage. Life cycle assessment was used to calculate the relative environmental cost of the studied mixes in comparison to a counterpart traditional Ordinary Portland Cement mortar. The optimal mix design exhibited high flexural strength (8.5 and 10.5 MPa, before and after high-temperature exposure, respectively), an unheated compressive strength equal to 69.5 MPa, and a post-heating residual one of 33.9 MPa, 7.7% mass loss and 3.4% thermal shrinkage. Mercury Intrusion Porosimetry along with Scanning Electron Microscopy with Energy Dispersive X-Ray Analysis were also performed on optimal mortar samples in order to link micro-structural heat-induced changes to residual (post-heating) macro-mechanical performances. Finally, when compared to OPC-based products, the optimized mortar mix resulted in 70% lower CO2 emissions indicating great potential for the construction sector where concern about environmental impact keeps growing.

Paper ini mengangkat kajian tentang Imam Ahmad Ibn Hanbal dalam mempertahankan argumentasinya di tengah kebijakan Mihnah yang diberlakukan khalifah Abasiyah (Makmun, Mu’tasim dan Watsiq) di mana diketahui banyak intelektual atau ulama pada masanya menjadi korban kekerasan dan penyiksaan oleh khalifah, ada yang langsung berubah sikap dan pendapatnya, namun berbeda dengan sang imam yang sangat konsisten dengan pendapat dan argumenya. Imam Ahmad bin Hambal merupakan salah seorang intelektual islam, ulama besar yang sampai hari ini mazhabnya berkembang di seluruh penjuru dunia. Tidak dipungkiri bahwa latar belakang sosial politik merupakan bagian dari proses muncul tumbuh dan berkembangnya Mazhab Hambali hingga hari ini. Paper ini merupakan penelitian deskriptif dengan pendekatan historis, yang terkait bagaimana terjadinya kebijakan mihnah dan apa yang melatarbelakangi munculnya kekerasan dan mengapa imam Ahmad Ibn Hanbal tidak berdusta saja untuk menghindari penyiksaan (mengingat beliau adalah seorang imam mujtahid yang dapat berfatwa) disesuaikan dengan kondisi yang dialami?. Fokus Paper ini mengungkap sejarah bagaimana peristiwa intimidasi dan kekerasan yang dialami imam hanbali oleh penguasa (khalifah). Dalam menemukan jawabanya penulis mencoba melihat dari kacamatad dengan teori Relasi kuasa (power relation) yang dikembangkan oleh Michel Foucault.

Published: February 2023

Background:
After a radial nerve injury, patients must weigh a complicated set of advantages and disadvantages to observation or surgery. We conducted semistructured interviews to characterize the decision-making process that these patients undertake.

Methods:
We recruited participants who were treated with expectant management (nonoperatively), received only a tendon transfer, or received a nerve transfer. Participants completed a semistructured interview that was transcribed and coded to identify recurring themes, to describe the influence of qualitative findings on treatment decision-making.

Results:
We interviewed 15 participants (5 expectant management, 5 tendon transfer only, and 5 nerve transfer). Participants’ primary concerns were returning to work, hand appearance, regaining motion, resuming activities of daily living, and enjoying hobbies. Delayed diagnosis and/or insurance coverage led 3 participants to change treatment from nerve transfer to isolated tendon transfer. Interactions with providers early in diagnosis and treatment had strong effects on how members of the care team were perceived. The hand therapist was the primary person who shaped expectations, provided encouragement, and prompted referral to the treating surgeon. Participants valued debate among the care team members regarding treatment, provided that medical terminology was explained.

Conclusions:
This study highlights the importance of initial, collaborative care in setting expectations for patients with radial nerve injuries. Many participants named returning to work and hand appearance as primary concerns. Hand therapists were the primary source of support and information during recovery.

Level of Evidence:
Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Case:
We describe the case of a 53-year-old male patient with a history of acute carpal tunnel syndrome (CTS) provoked by a radio-opaque mass on the palmar side of the wrist. Although the mass disappeared in new radiographs 6 weeks later without any intervention apart from the carpal tunnel release, excisional biopsy was conducted on the residue, revealing tumoral calcinosis.

Conclusion:
Both acute CTS and spontaneous resolution are clinical manifestations of this rare condition on suspicion of which biopsy can be avoided by following a “wait and see” strategy.

Abstract
—A 6-meter core of the Holocene sediments in Lake Dukhovoe is studied. The material composition of the core is heterogeneous and has clear bedding. Lacustrine sediments are represented by the upper 293 cm. Each bed of the sediments is subjected to microbiological analysis. A high total number of heterotrophic bacteria is revealed in the upper (0–15 cm) and deeper (110–150 cm) sapropel intervals. Sulfate-reducing bacteria are identified only in Chrysophyceae cysts. The CaO/Fe2O3 ratio shows the degree of “carbonate content” of bottom sediments. It is low in the lake sapropel (0.2), which indicates the geochemical specificity (carbonate-free sapropel). Na, Mg, Al, Si, Al, Ca, Fe, Mn, Zr, and Cr concentrations in sapropel are within the average concentrations for the Earth’s crust, shale, and oceanic pelagic clays, while U and Mo concentrations exceed them. Phytoplankton is enriched in phosphorus (biogenic element) and chalcophile elements (Zn, Cd, Sn, Sb, Hg, Pb, and Cu), which characterize the pollution of the modern atmosphere of the Baikal region. Diagenetic processes result in the transformation of the pore waters, namely an increase in mineralization as compared to lake water, an increase in the concentrations of biogenic components (HCO3-, NH4+, NO3-, and PO43-) and a decrease in SO42-. Pyrite framboid accumulations are revealed in organomineral sediments below the horizon of 200 cm, and iron phosphates represented by vivianite are identified in sapropel.

A Data Science Approach to Uncertainty Evaluation in Fault-Seal Analysis for Exploration Applications in Siliciclastic Reservoirs
Authors: Wilson Paul 
Published: February 2023

Summary
Fault-seal analysis is used to understand the risk of hydrocarbons leaking out of a trap across bounding faults. There is a broad standard industry workflow for this analysis in clastic rocks, involving building a structural framework of the key seismic horizons and faults, estimating the clay content of the stratigraphy, predicting fault clay content using an algorithm such as shale gouge ratio (SGR), converting the predicted clay content to capillary threshold pressure, and calculating sealing capacity using the reservoir fluid properties. The inputs to the analysis are typically subject to considerable uncertainty that is difficult to understand and evaluate. One approach is to create “end member” scenarios to evaluate the impact of the key uncertainties, but this gives an incomplete picture and only a limited number of scenarios can be run and analyzed in the time typically available. The approach outlined here instead uses an automated workflow that runs hundreds of scenarios with stochastically varying input parameters. Data-science techniques combining domain expertise, mathematics and statistics, and computer coding are used to analyze and build models of the results. The advantages of the approach over a traditional fault-seal analysis workflow are that a wider range of input uncertainties can be considered, and that the results of a large number of realizations can be consolidated and visualized in ways that are specific to the problem being addressed and useful to the geologist undertaking the analysis. A key advantage is that the uncertainty inherent in this type of analysis can be explicitly incorporated, and the impact of the uncertainty clearly understood and communicated to decision-makers. Similar techniques could be applied to other geological analyses where uncertainty is an issue.

Abstract
Carbonate karst geothermal resources are widely distributed and have large reserves in North China. Nowadays, the scale of exploitation and utilization of the carbonate karst geothermal resources is gradually increasing. In this work, a geothermal exploitation area where the karst geothermal reservoirs are exploited on a large scale, is selected as the study area, and methods including experiment and numerical simulation are used to study the exploitation-induced ground subsidence problems based on the long-term water level monitoring data of the geothermal reservoir. Through analyses of ground subsidence caused by water level change of the geothermal reservoir, the following conclusions were obtained. The water level drawdown of different types of geothermal reservoirs had different effects on ground subsidence. The maximum ground subsidence of the study area caused by the water level decline of the Jx w carbonate geothermal reservoir was only 0.29 mm/a from 1983 to 2019, which is generally insignificant. In contrast, the same water level change of the N m sandstone geothermal reservoir was predicted to cause 8.9 mm/a ground subsidence. To slow down or even prevent the ground subsidence, balanced production and reinjection are required. From the result of this work, the decline of the water level of the Jx w carbonate geothermal reservoir caused by current large-scale geothermal exploitation will not cause serious ground subsidence. However, attention should be paid to the N m sandstone type geothermal reservoirs as their structures are much more sensitive to the water pressure change.

Abstract

Variation is a key concept in every biological aspect, particularly in medical genetics. In this field, each genetic variant is evaluated mostly as an independent entity in respect of its clinical importance. This approach may be sufficient to detect the pathogenic variants in single-gene disorders. However, in most of the complex diseases, the combination of the variants in specific gene networks, rather than the presence of a certain single variant, predominates. Therefore, in case of a complex disease, the disease status can be evaluated by considering it as the success level of a team composed of certain variants. To assess the feasibility of this approach, we tested the effectiveness of high-dimensional modelling of gene network-restricted variants in distinguishing a disease status. To evaluate the proposed method, we selected two gene networks, mTOR and TGF-β. For each pathway, we generated 400 control and 400 patient group samples. The considered mTOR and TGF-β pathways contain 31 and 93 genes of varying sizes, respectively. We generated Chaos Game Representation images for each gene sequence to obtain 2-D binary patterns. Produced patterns were arranged in succession, and a 3-D tensor structure was achieved for each gene network. Features for each data sample were acquired by exploiting Enhanced Multivariance Products Representation to 3-D data. The features were split as training and testing vectors. The training vectors were employed to train a Support Vector Machines classification model. We managed to achieve more than 96% and 99% classification accuracies for mTOR and TGF-β networks, respectively, using a limited amount of training samples.
Furin-cleavage site is present in a short loop between an antiparallel β-strand in SARS-CoV2 Spike protein at S1/S2 junction

Published: February 2023

Abstract
Furin cleavage-site (CS) present between the S1/S2 junction in SARS-CoV2 spike (S) protein is critical to drive the fusion of SARS-CoV2 with the host cell. SARS-CoV2 falls in the sarbecovirus lineage that doesn’t comprise of furin CS and therefore makes its origin enigmatic. The available wild-type (Wt) SARS-CoV2 S protein with PDB ID: 6yvb lacks a stretch of amino acid including furin CS as well. All investigators till date have shown this stretch existing in the form of a loop. We are for the first time reporting that this stretch comprises of 14 amino acid residues (677QTNSPRRARSVASQ689), forming an antiparallel β-sheet comprising of PRRAR furin CS. We observed the presence of this antiparallel β-sheet in MERS spike protein as well. While switching over from Wt. SARS-CoV2 with PRRAR furin CS to B.1.1.7 variant with HRRAR furin CS, we found 3% increase in the percentage content of β stands. Interestingly, we found that the change of B.1.1.7 to B.1.617 variant comprising of RRRAR furin CS shifted the percentage secondary structure back to that found in Wt. SARS-CoV2. We anticipate that this β-sheet is used as a docking site by host cell proteases to act on furin-CS. Additionally, we studied the interaction of modeled SARS-CoV2 S protein with transmembrane protease, serine 2 (TMPRSS2), and furin proteases, which clearly highlighted that these proteases exclusively uses furin CS located in β-sheet to cleave the SARS-CoV2 S protein at its S1/S2 junction.

Abstract
Lower WHO grade II and III gliomas (LGGs) are characterized by widespread genetic and transcriptional heterogeneity, yet little is known about the heterogeneity of the DNA Damage Repair (DDR), its function in tumor biology, coupling with the transcriptome and tumor microenvironment (TM) and its possible impact for tumor development. In this study, the DNA damage repair (DDR) alterations among LGG have been studied via multi-omics data integration. For this, LGG patients have been grouped into distinct subtypes (DDR-activated and the DDR-suppressed subtype) based on different clinicalparameters and molecular characteristics. The differences in gene mutation, immune spectrum, and immune cell infiltration between the two DDR subtypes were compared. We generated DDR subtype features (DDR scores) to implement DDR classification in LGG and confirmed the results using a multi-layer data cohort.The DDR activation subgroup was found to be associated with poorer overall survival based on molecular subtypes, and clinicopathological features of advanced-age and higher-grade were more common in the DDR-activated subgroup. DDR-suppressed subtypes also exhibited more frequent mutations in IDH1. We also found significant upregulation of activated immune cells in the DDR-activated subgroup, which indicates significant influence posed by infiltration of immune cells on tumor progression as well as immunotherapeutic responses. In addition, six DDR genes were selected to construct a DDR signature of LGG, dividing patients into low- and high-risk groups. The QRT-PCR results showed that the expression levels of CDK1, CDK2, TYMS, SMC4, and WEE1 were found to be considerably higher for LGG samples compared to normal brain tissue samples (p < 0.05).In conclusion, our work sheds light on the DDR heterogeneity of LGG and advances our knowledge of the molecular pathways in DDR that lead to LGG.
Aerial Image Dehazing Based on Boundary Constraint and Color Correction for Target Detection
Authors: Tang Chaoying , Ren Xue , Wang Biao 
Published: February 2023

Abstract

Detecting objects in aerial images is very important for surveillance, security and military applications. The quality of hazy aerial images is severely degraded because the image acquisition device is far away from the ground target. Due to the small change in scene depth, the atmospheric light estimation is prone to deviation. Therefore, traditional image dehazing methods cannot achieve satisfactory results. In this paper, we design a dehazing algorithm based on boundary constraint and color correction to enhance image details and improve accuracy of target detection. The boundary constraint is used to obtain the medium transmission of the structure layer after image decomposition. The transmission is optimized by the context regularization based on the weighted L1 norm to obtain a dehazed structure layer with clear edges. Then the dehazed structure layer and the enhanced texture layer are combined, and the image brightness is adjusted through blind inverse gamma correction to improve the visual effect. Experiments show that our algorithm can enhance the contrast of aerial images and is better than other methods in improving the accuracy of target detection in hazy aerial images.
