Abstract
This study aimed to assess the feasibility of diagnosing secondary pulmonary fungal infections (PFIs) in patients with hematological malignancies (HM) using computerized tomography (CT) imaging and a support vector machine (SVM) algorithm. A total of 100 patients with HM complicated by secondary PFI underwent CT scans, and they were included in the training group. Concurrently, 80 patients with the same underlying disease who were treated at our institution were included in the test group. The types of pathogens among different PFI patients and the CT imaging features were compared. Radiomic features were extracted from the CT imaging data of patients, and a diagnostic SVM model was constructed by integrating these features with clinical characteristics. Aspergillus was the most common pathogen responsible for PFIs, followed by Candida, Pneumocystis jirovecii, Mucor, and Cryptococcus, in descending order of occurrence. Patients typically exhibited bilateral diffuse lung lesions. Within the SVM algorithm model, six radiomic features, namely the square root of the inverse covariance of the gray-level co-occurrence matrix (square root IV), the square root of the inverse covariance of the gray-level co-occurrence matrix, and small dependency low gray-level emphasis, significantly influenced the diagnosis of secondary PFIs in patients with HM. The area under the curve values for the training and test sets were 0.902 and 0.891, respectively. Therefore, CT images based on the SVM algorithm demonstrated robust predictive capability in diagnosing secondary PFIs in conjunction with HM.

Abstract

Objectives
An isotope dilution liquid chromatography-tandem mass spectrometry (ID-LC-MS/MS)-based candidate reference measurement procedure (RMP) was developed and validated to accurately measure serum and plasma concentrations of carbamazepine.

Methods
Quantitative nuclear magnetic resonance (qNMR) spectroscopy was used to determine the absolute content of the reference material, ensuring its traceability to SI units. The separation of carbamazepine from potential interferences, whether known or unknown, was achieved using a C18 column. A protein precipitation protocol followed by a high dilution step was established for sample preparation. Assay validation and determination of measurement uncertainty were performed in accordance with the guidelines of the Clinical and Laboratory Standards Institute, the International Conference on Harmonization (ICH), and the Guide to the Expression of Uncertainty in Measurement (GUM). In order to demonstrate equivalence to the already existing RMP a method comparison study was performed.

Results
The RMP was proven to be highly selective and specific with no evidence of a matrix effect, allowing for quantification of carbamazepine within the range of 0.800–18.0 μg/mL. Intermediate precision and repeatability (n=60 measurements) was found to be <1.6 % and <1.3 % over all concentration levels and independent from the matrix. The relative mean bias ranged from −0.1 to 0.6 % for native serum and from −0.3 to −0.1 % for Li-heparin plasma levels. The measurement uncertainties for single measurements and target value assignment were found to be <1.8 % and <1.3 %, respectively. Method comparison showed a good agreement between the Joint Committee of Traceability in Laboratory Medicine (JCTLM) listed RMP and the candidate RMP resulting in a Passing–Bablok regression equation with a slope of 1.01 and an intercept of −0.01. The bias in the patient cohort was found to be 0.9 %.

Conclusions
We present a novel LC-MS/MS-based candidate RMP for carbamazepine in human serum and plasma which provides a traceable and reliable platform for the standardization of routine assays and evaluation of clinically relevant samples.

Abstract

Objectives
Data generation in clinical settings is ongoing and perpetually increasing. Artificial intelligence (AI) software may help detect data-related errors or facilitate process management. The aim of the present study was to test the extent to which the frequently encountered pre-analytical, analytical, and postanalytical errors in clinical laboratories, and likely clinical diagnoses can be detected through the use of a chatbot.

Methods
A total of 20 case scenarios, 20 multiple-choice, and 20 direct questions related to errors observed in pre-analytical, analytical, and postanalytical processes were developed in English. Difficulty assessment was performed for the 60 questions. Responses by 4 chatbots to the questions were scored in a blinded manner by 3 independent laboratory experts for accuracy, usefulness, and completeness.

Results
According to Chi-squared test, accuracy score of ChatGPT-3.5 (54.4 %) was significantly lower than CopyAI (86.7 %) (p=0.0269) and ChatGPT v4.0. (88.9 %) (p=0.0168), respectively in cases. In direct questions, there was no significant difference between ChatGPT-3.5 (67.8 %) and WriteSonic (69.4 %), ChatGPT v4.0. (78.9 %) and CopyAI (73.9 %) (p=0.914, p=0.433 and p=0.675, respectively) accuracy scores. CopyAI (90.6 %) presented significantly better performance compared to ChatGPT-3.5 (62.2 %) (p=0.036) in multiple choice questions.

Conclusions
These applications presented considerable performance to find out the cases and reply to questions. In the future, the use of AI applications is likely to increase in clinical settings if trained and validated by technical and medical experts within a structural framework.

Abstract
BaTi5O11 nanocrystals were synthesized by a hydrothermal method, and the effect of oleic acid (OA) in the Ba–Ti precursors on morphologies of BaTi5O11 nanocrystals was investigated. As the OA/(Ba2+ + Ti4+) molar ratio ranged from 0 to 8, single-phase BaTi5O11 nanocrystals were synthesized at 260 °C for 20 h. When OA reagent was not added to the precursors, rice-like BaTi5O11 nanocrystals were obtained. As the OA/(Ba2+ + Ti4+) molar ratio was 1, elongated lath-like BaTi5O11 nanocrystals were synthesized with the width of about 130 nm, thickness of about 50 nm and length of about 400 nm. With increasing the OA/(Ba2+ + Ti4+) molar ratio from 1 to 6, the grain size of elongated lath-like BaTi5O11 nanocrystals gradually decreased. As the OA content increased, the amount of adsorbed OA molecules on the surface of Ti(OH)

nucleus increased and hindered the reaction of Ba2+ ions with Ti(OH)

nucleus, which caused the decrease of grain size of lath-like BaTi5O11 nanocrystals. When the BaTi5O11 nanocrystals were synthesized at OA/(Ba2+ + Ti4+) molar ratio of 1, they had the largest dielectric constant (ε
r) of 40.9 at 5 GHz.

Published: December 2023

Abstract
We present a radiative cooling material capable of enhancing albedo while reducing ground surface temperatures beneath fielded bifacial solar panels. Electrospinning a layer of polyacrylonitrile nanofibers, or nanoPAN, onto a polymer-coated silver mirror yields a total solar reflectance of 99 %, an albedo of 0.96, and a thermal emittance of 0.80. The combination of high albedo and high emittance is enabled by wavelength-selective scattering induced by the hierarchical morphology of nanoPAN, which includes both thin fibers and bead-like structures. During outdoor testing, the material outperforms the radiative cooling power of a state-of-the-art control by ∼20 W/m2 and boosts the photocurrent produced by a commercial silicon cell by up to 6.4 mA/cm2 compared to sand. These experiments validate essential characteristics of a high-albedo radiative-cooling reflector with promising potential applications in thermal and light management of fielded bifacial panels.
Magnetic moment of Mn2+ ions that are responsible for the ferromagnetic properties of ZnO:Mn nanocrystals
Authors: Kovalenko O.V. , Vorovsky V.Yu. 
Published: December 2023

The calculation of the magnetic moment of Mn2+ ions in ZnO:Mn (2 at%.) nanocrystals obtained by ultrasonic pyrolysis of aerosol which are responsible for their ferromagnetic properties is given. In order to investigate the influence of structural defects on the value of magnetic moment the samples were heat treated in air. The calculation was performed on the basis of the analysis of magnetization curves and EPR spectra. It was shown that the defective state of ZnO:Mn nanocrystals has a significant effect on the magnetic moment. The values of magnetic moment for the synthesized sample significantly exceed the values of magnetic moment compared to similar nanocrystals obtained by other methods. The assumption is made that this result is due to the presence of an additional component in the magnetization of the defective samples. In addition to the paramagnetism of Mn2+ ions, there may be the paramagnetism of the defective shell of ZnO:Mn nanocrystals. After the elimination of structural defects by heat treatment of samples in air and in a gas mixture with hydrogen, the magnetic moment for Mn2+ ions, which form the ferromagnetic properties of nanocrystals, was determined. The value of this magnetic moment is 0.02µB, where µB is the Bohr mangiton. Such ions, according to the model of bound magnetic polarons, are part of ferromagnetic clusters and take part in the formation of the ferromagnetic properties of the samples.

Published: December 2023

The ferrogarnet structures consisting from one- to three- layers of monocrystalline yttrium-iron garnet Y3Fe5O12 (YIG) films, two- layered YIG - La,Ga:YIG and two- layered {Y,Sm,Lu}3(Fe,Ga)5O12 -YIG structures were grown by liquid-phase epitaxy (LPE) method on gadolinium - gallium garnet Gd3Ga5O12 (GGG) substrates of (111) orientation. The obtained layered ferrogarnet structures were studied by the methods of ferromagnetic resonance (FMR) and magnetostatic wave (MSW) interference. The two- and three- layered YIG structures have a wide FMR line width (∆H). For the three- layered YIG structures with the total thickness of 68-102 μm ∆H = 5,7- 11,5 Oe. The line width ∆H = 0,34 – 1,22 Oe correspond to the two- layered (Y,Sm,La)3(Fe,Ga)5O12 – YIG structures with thicknesses from 3 to 65 μm. Individual layers in all structures are characterized by similar or different saturation magnetizations (4πMs).The frequency MSW separation in the YIG - La,Ga:YIG layered structure was observed. It was shown that the propagation losses of MSW in one- and two- layered structures increase with decreasing wavelength of MSW and transition to a two- layered structure.
Drivers of moral hazard in banks
Authors: Jović Željko 
Published: December 2023

AbstractThe objective of this research is to identify factors that determine the moral hazard in banks by using discrete choice models (probit and logit regression). A specially constructed indicator was used to quantitatively assess moral hazard as the average difference between the better rating of a client in a bank and the most conservative rating of the same client in the banking sector. This is an example where moral hazard manifests itself as the tendency of management in banks to underestimate credit risk. The results showed that state-owned banks and foreign privately-owned banks with evident problems at the level of their headquarters had higher values of this quantitative indicator of moral hazard. Also, banks whose financial result and capital are highly sensitive to a small increase in non-performing loans, as well as banks that at any time in the observed period had a problem with meeting regulatory capital requirements, showed a greater propensity to moral hazard, as measured by this indicator. In the above cases, in the absence of quality corporate governance, management in banks tends to show performance better than it actually is. The obtained results for Serbia in comparison with the previous research give the possibility to quantitatively confirm additional specific factors important for explaining moral hazard (composite variable of the type of ownership and capital restrictions, variables that perform only the transmission of certain forms of management behaviour, size, capital and profit sensitivity, credit risk level, etc.), in addition to the common factors of moral hazard, such as the type of ownership in the bank, capital restrictions, etc.

Published: December 2023

Clustering of regions, not only by economic parameters, but also by tax parameters is a new direction of economic research. The purpose of this article is to group the regions of the Russian Federation according to the industry specifics of their tax revenues and identify common features for each of the established clusters. The industry specifics of the regions in terms of the parameter of tax revenues of budgets are investigated using cluster analysis using the ORANGE software product. The empirical basis of the study was the data of the Federal Tax Service on the structure of tax revenues of the consolidated budget of the regions by type of economic activity for 2017. This period is purely conditional and is used only for the purpose of testability of the method used to find the optimal number of clusters on the territory of Russia for further research. The conducted research has shown that the regions of the Russian Federation have specifics in accordance with the sectoral structure of tax revenues. According to the results of the analysis, nine clusters were identified. Of the nine clusters, three have industry — specific types of economic activity — manufacturing and mining. In two clusters, tax revenue indicators are above average for almost most types of economic activity. Four clusters demonstrate high tax revenues for such types of economic activities as transportation and storage, public administration, education, healthcare, construction, as well as manufacturing, and mining. The data obtained make it possible to develop a «personalized» tax policy of each entity.

Published: December 2023

Introduction. One of the areas of maintenance therapy in oncology is dental support for patients, the effectiveness of which is currently low. The prevalence of complications of anticancer treatment reaches 100 % of cases. This negatively affects the prognosis of the treatment of an oncological patient and the quality of his life.Aim. To analyze the factors that reduce the effectiveness and efficiency of accompanying dental therapy.Materials and methods. Retrospective analysis of clinical observations of the Department of General and Clinical Dentistry named after V.S. Dmitrieva was carried out on the basis of the Russian Scientific Center of Roentgenoradiology.Results. Factors decreasing the quality and effectiveness of accompanying dental therapy are dental unpreparedness of patients prescribed antitumor treatment, very low level of personal hygiene of the oral cavity, as well as insufficient number of available highly effective techniques for treatment and prevention of radiation injuries.Absence of professionals having skills in dental care for oncological patients at all stages of routing (from diagnosis to rehabilitation after completion of antitumor treatment) is another factor contributing to low effectiveness of accompanying therapy and, in our opinion, the most significant. The current clinical guidelines governing the process of examination and treatment of patients with malignant tumors do not contain detailed instructions for dentists about the techniques, approaches of dental accompaniment, and the necessary medications.Conclusion. Factors that reduce the effectiveness and efficiency of dental accompanying therapy have been identified: the lack of trained dental personnel with the skills to provide care to cancer patients; underestimation of the role of a dentist in solving general clinical problems; lack of a systematic approach to providing accompanying therapy to cancer patients; lack of continuity between the polyclinic link and the stationary.
