Comparison of Foraging Interactive D-prime and Angular Indication Measurement Stereo with different methods to assess stereopsis
Authors: Neupane Sonisha , Skerswetat Jan , Bex Peter J. 
Published: June 2024

Purpose
Stereopsis is a critical visual function, however clinical stereotests are time-consuming, coarse in resolution, suffer memorization artifacts, poor repeatability, and low agreement with other tests. Foraging Interactive D-prime (FInD) Stereo and Angular Indication Measurement (AIM) Stereo were designed to address these problems. Here, their performance was compared with 2-Alternative-Forced-Choice (2-AFC) paradigms (FInD Stereo only) and clinical tests (Titmus and Randot) in 40 normally-sighted and 5 binocularly impaired participants (FInD Stereo only).

Methods
During FInD tasks, participants indicated which cells in three 4*4 charts of bandpass-filtered targets (1,2,4,8c/° conditions) contained depth, compared with 2-AFC and clinical tests. During the AIM task, participants reported the orientation of depth-defined bars in three 4*4 charts. Stereoscopic disparity was adaptively changed after each chart. Inter-test agreement, repeatability and duration were compared.

Results
Test duration was significantly longer for 2-AFC (mean = 317s;79s per condition) than FInD (216s,18s per chart), AIM (179s, 60s per chart), Titmus (66s) or RanDot (97s). Estimates of stereoacuity differed across tests and were higher by a factor of 1.1 for AIM and 1.3 for FInD. No effect of stimulus spatial frequency was found. Agreement among tests was generally low (R2 = 0.001 to 0.24) and was highest between FInD and 2-AFC (R2 = 0.24;p<0.01). Stereoacuity deficits were detected by all tests in binocularly impaired participants.

Conclusions
Agreement among all tests was low. FInD and AIM inter-test agreement was comparable with other methods. FInD Stereo detected stereo deficits and may only require one condition to identify these deficits. AIM and FInD are response-adaptive, self-administrable methods that can estimate stereoacuity reliably within one minute.
Parvimonas micra Bacteremia: A Rare Complication After Esophagogastroduodenoscopy for Upper Gastrointestinal Bleeding

Published: June 2024

ABSTRACT

Parvimonas micra bacteremia is rarely encountered in clinical practice. When it is, patients usually have underlying periodontal disease or colorectal carcinoma. To the best of our knowledge, this is the first case of P. micra bacteremia in a patient without the predisposing risk factors listed above. We postulate that this occurred because of translocation across an interrupted gut-blood barrier in the setting of an acute upper gastrointestinal bleed. We present this case to highlight the importance of identifying and treating P. micra bacteremia because it can prevent commonly encountered sequelae of untreated bacteremia and improve outcomes.

Published: June 2024

Abstract
The intelligent university teaching detection system can effectively improve the teaching efficiency of university classrooms and improve the teaching environment. In order to improve the quality of online teaching supervision, this study combines digital monitoring technology to monitor the online teaching process in colleges and universities, and analyzes the method and process of using the equivalence line and the rotation theorem to estimate the projection angle. This work applies a projection method to digital teaching detection, improves the algorithm based on requirements, uses factor improvement methods to improve the problems in model application, uses requirement analysis methods to construct a system model, and uses experimental analysis methods to verify the effectiveness of the proposed algorithm and model. With the support of simulation platforms and mathematical statistical methods, the effectiveness of the system model is verified in this work. From the evaluation results, it can be seen that the evaluation results of the system model in this work are distributed between [84,92], indicating that the use of the system in this study is very excellent. The experimental research shows that the digital online monitoring technology proposed in this study can monitor students in real time in online teaching in colleges and universities, effectively improve the participation of students in the online teaching process, and play an important role in improving the quality of teaching.
Speaker positioning in academic instruction: insights from corpus analysis
Authors: Kashiha Hadi 
Published: June 2024

Abstract
While previous research has extensively explored the ways writers project themselves into discourse and engage with readers across various written genres, limited attention has been given to understanding how university lecturers express their stance, i.e., expression of positioning and commitment towards propositions and students. To address this gap, this study proposes a functional framework for analyzing stance features in academic lectures using 160 lecture transcripts from four broad disciplinary divisions: arts and humanities, social sciences, physical sciences, and medical sciences. The analysis focuses on the extent and manner in which lecturers position themselves in discourse to steer students towards their intended interpretations. The findings indicate that lecturers, regardless of their disciplinary background, express their stance through seven distinct functions, including evaluating their level of commitment, posing questions, interacting with the audience, indicating obligations, emphasizing topics, initiating discourse, and previewing exam-related content. The findings have significant pedagogical implications, especially for educators and EAP practitioners seeking to improve lecture comprehension and engagement among students. Understanding how lecturers use language to interact with students and structure academic discourse can empower teachers to adopt similar stances for guiding students in engaging with course materials.
The Centralized Management of Folk Art Trade in Hungary
Authors: Cseh Fruzsina 
Published: June 2024

AbstractThe decorated artifacts of rural craft industries were the forerunners of the products which, from the late 19th century, were made for the organized trade that entered the global market and met the needs of the Hungarian market. The production was managed by the increasingly numerous cottage industry associations, later cottage industry cooperatives and independent companies. Until World War II, craft and folk art products were marketed by centrally managed organizations, as well as by individual entrepreneurs, commercial travelers, trading companies, and cottage industry cooperatives. From 1948 onwards, the marketing of the products of cottage industry cooperatives was exclusively in the hands of state-controlled domestic trading and export companies. After the political regime change in Hungary in 1989, the applied folk arts cooperatives continued to operate for some time, but the centrally managed trading companies ceased to exist. The cooperatives carried out commercial activities by building on their previous relationships. By the 1990s, however, the global market for folk art products and the economic conditions for their production in Hungary had changed, and the folk art products of the cottage industry cooperatives have been phased out. This paper focuses on the history of centrally managed institutions of commerce from the 1870s to 1989 and their aftermath up to the 1990s.

Published: June 2024

AbstractMyricetin has been reported to have a wide variety of beneficial physiological functions. The present study investigated the antihyperlipidaemic activity of myricetin against hyperlipidaemia of high-fat diet-fed obese rats. The four-week antihyperlipidaemic activity was assayed by giving different doses of myricetin to hyperlipidaemic rats. Results showed that myricetin could reduce the harm caused by oxidative stress, decrease thiobarbituric acid reactive substances value, and decrease total cholesterol and triacylglycerol levels of hyperlipidaemic rats. Quantitative analysis of gene expression showed that myricetin's lipid-lowering activity can be activated by downregulating gene expression of fatty acid synthase (FAS) and peroxisome proliferator-activated receptor-γ (PPARγ) with upregulation of hormone-sensitive lipase (HSL) mRNA level. Thus, myricetin had significant health benefits and could be explored as a potentially promising dietary supplement for treating hyperlipidaemia.

The mangrove ecosystem of Cemara Kulon Village has the potential for fishery resources which has decreased in line with various anthropogenic activities. This study aims to determine the composition of fish and analyze the status of the fish community structure and its relation to the physical-chemical aspects of the waters in the mangrove ecosystem of Cemara Kulon Village. This research was conducted over a period of three months in the mangrove ecosystem of Cemara Kulon Village. The method used in this research was descriptive quantitative purposive and composite sampling at 3 research stations. Parameters observed in this study were relative abundance, diversity, uniformity, dominance, and the relationship between community structure and aquatic physico-chemical parameters. During the study, 508 fish were caught, consisting of 20 species from 16 families. The value of diversity was in the moderate category with a ranged of 1.87-2.50; the uniformity value was in the moderate category with a ranged of 0.41-0.46 and the dominance value was in the low category with a ranged of 0.11-0.22. Based on the results of the Canonical Correspondence Analysis (CCA) revealed that fish diversity was affected by light transparency and DO, the uniformity of fish was affected by temperature, and the dominance of fish was affected by ammonia. The fish community structure was categorized as unstable which was influenced by water quality.
Beyond the Pulpit in the Catholic Church of South Korea:Responding to Dr. Sabrina Müller
Authors: Kang Dong 
Published: June 2024

Dr. Sabrina Müller advocates nurturing diversity in preaching by integrating feminist and cultural insights into the field of homiletics. In response, this paper compares her research to another study on feminism, emphasizing that gender and culture encompass more than just sex and race. Further, this paper attributes the stagnancy of the preaching ministry within the Catholic Church in South Korea to a lack of motivation to adapt to changing times and a tendency to rest on the laurels of past triumphs, particularly in the realm of modern democratic history. To address the issue, embracing the Synodality of the Catholic Church, which aligns with Dr. Müller’s focus on diversity in the preaching ministry, is imperative. This approach offers a remedy for the church to overcome the monotonous tendencies of clericalism and the gender-discriminatory practices influenced by Confucianism.

Key Points

We provide an atlas of cross-sectional and longitudinal serum and urine metabolite associations with eGFR and urine albumin-creatinine ratio in an older community-based cohort.Metabolic profiling in serum and urine provides distinct and complementary insights into disease.

Background
Metabolites represent a read-out of cellular processes underlying states of health and disease.

Methods
We evaluated cross-sectional and longitudinal associations between 1255 serum and 1398 urine known and unknown (denoted with “X” in name) metabolites (Metabolon HD4, 721 detected in both biofluids) and kidney function in 1612 participants of the Atherosclerosis Risk in Communities study. All analyses were adjusted for clinical and demographic covariates, including for baseline eGFR and urine albumin-creatinine ratio (UACR) in longitudinal analyses.

Results
At visit 5 of the Atherosclerosis Risk in Communities study, the mean age of participants was 76 years (SD 6); 56% were women, mean eGFR was 62 ml/min per 1.73 m2 (SD 20), and median UACR level was 13 mg/g (interquartile range, 25). In cross-sectional analysis, 675 serum and 542 urine metabolites were associated with eGFR (Bonferroni-corrected P < 4.0E-5 for serum analyses and P < 3.6E-5 for urine analyses), including 248 metabolites shared across biofluids. Fewer metabolites (75 serum and 91 urine metabolites, including seven metabolites shared across biofluids) were cross-sectionally associated with albuminuria. Guanidinosuccinate; N2,N2-dimethylguanosine; hydroxy-N6,N6,N6-trimethyllysine; X-13844; and X-25422 were significantly associated with both eGFR and albuminuria. Over a mean follow-up of 6.6 years, serum mannose (hazard ratio [HR], 2.3 [1.6–3.2], P = 2.7E-5) and urine X-12117 (HR, 1.7 [1.3–2.2], P = 1.9E-5) were risk factors of UACR doubling, whereas urine sebacate (HR, 0.86 [0.80–0.92], P = 1.9E-5) was inversely associated. Compared with clinical characteristics alone, including the top five endogenous metabolites in serum and urine associated with longitudinal outcomes improved the outcome prediction (area under the receiver operating characteristic curves for eGFR decline: clinical model=0.79, clinical+metabolites model=0.87, P = 8.1E-6; for UACR doubling: clinical model=0.66, clinical+metabolites model=0.73, P = 2.9E-5).

Conclusions
Metabolomic profiling in different biofluids provided distinct and potentially complementary insights into the biology and prognosis of kidney diseases.

The work is related to the study of the morphological features of silicon wires arrays combined with a nanomaterial of natural origin, a bacterial ferritin-like protein Dps, and their relationship with the composition of the surface and interior. A silicon wires array was formed by metal-assisted wet chemical etching. To obtain recombinant protein, Escherichia coli BL21*(DE3) cells were used as producers, and purification was carried out by the chromatography method. The combination of silicon wires with protein molecules was carried out by layering under laboratory conditions, followed by drying. The resulting hybrid material was studied by scanning electron microscopy and X-ray photoelectron spectroscopy. The initial silicon wires array had sharp boundaries on the surface. The diameter of the silicon wires was about 100 nm, while the distances between the wires can vary widely, reaching several hundred nanometres or be less than 100 nanometres, depending on the formation conditions, in the absence of noticeable transition layers. The pores formed in this way are available for filling with protein during deposition. The effectiveness of using the scanning electron microscopy method to study the morphology of the hybrid material “silicon wires – bacterial protein Dps” as well as X-ray photoelectron spectroscopy method together with ion etching for the investigation of the composition and physico-chemical of the hybrid material was demonstrated. Complementary results have shown that the molecular culture, which is a solution of oligomers of the recombinant Dps protein of E.coli bacterial cells, can penetrate deep into the pores of the silicon wires array with an extremely developed surface. The possibility of the control of the filling of silicon wires arrays by varying the pore morphology and other modes of formation of structuresand their surface has been demonstrated. The obtained data can be used to study the possibilities of the functionalization of the developed surface of silicon wires by their driven coating with controlled delivery of biohybrid material.

Due to their multi-functionality, spinel ferrites, both doped and undoped, are promising materials for a wide range of practical applications, including catalysis, sustainable production of hydrogen and СО2 deposition, electronic and magnet devices, as well as antibacterial agents. Recently, nanosized ferrites have been actively tested as catalysts in Fenton-like processes of deep oxidative degradation of organic substances in order to purify waste waters of different dyes, phenol and its derivatives, and antibiotics. The goal of this work was to establish the catalytic activity of СоFe2O4 nanopowder synthesisedusing citrate combustion in the reaction of oxidative degradation of 2,4-dinitrophenol upon the activation of the process with UV radiation. Using citrate combustion, we synthesised the impurity-free nanopowder of CoFe2O4 cobalt ferrite with the average size of particles of about 70 nm and a pronounced agglomeration of particles. The cobalt spinel was tested as a catalyst of Fentonlike reaction of oxidative degradation of 2,4- dinitrophenol with UV radiation of l = 270 nm. This process was differentiated with the sorption of dinitrophenol on a nanosized catalyst. The degree of degradation of 2,4-dinitrophenol in a Fenton-like reaction without the CoFe2O4 catalyst was 14 %, while in the presence of a nanosized catalyst it increased up to 80 %. The effective oxidative degradation of the pollutant was performed in a less acidic environment as compared to a classic Fenton process with a rather large initial concentration of dinitrophenol. This allowed considering the nanosized CoFe2O4 as a promising catalyst of Fenton-like of waste waters purification through deep oxidative degradation of toxins.

Authors: Fedorov Pavel P. , Chernova Elena V. 
Published: June 2024

The literature data on the study of phase equilibria in systems zirconia with yttria and scandia are analysed. Possible schemes of low-temperature phase equilibria in ZrO2-Y2O3 and ZrO2-Sc2O3 systems are presented taking into account the third law of thermodynamics. The coordinates of non-variant transformations in these systems are tabulated. A sign of non-equilibrium states is the observation of non-diffusion processes of ordering of solid solutions. The modified cryoscopy method is used to calculate the distribution coefficients of scandia and yttria during the crystallization of the ZrO2 melt. The possibilities for the existence of a set of ordered phases in the ZrO2-Y2O3 system and diffuse phase transition in the cubic modification of zirconia are discussed.

Published: June 2024

Vital cellular processes depend on the controlled transport of metal ions across biological membranes. A biological membrane is a complex system consisting of lipids and proteins, that is why simplified systems, in particular monomolecular layers, are used to model it. This work presents the results of a study of the interaction of zinc ions from the aqueous subphase with the Langmuir monolayer of arachidic acid. The study was carried out for the first time and used total external reflection X-ray absorption spectroscopy. It considers the influence of the concentration of a ZnCl2 aqueous subphase solution on the local environment of zinc ions when interacting with the lipid monolayer immediately after its formation. The theoretical analysis of experimental XANES spectra showed that one of the interaction ways of arachidic acid molecules with zinc ions immediately after the monolayer formation is an intramolecular interaction with the formation of spodium bonds between the zinc cation and the OH carboxyl group of arachidic acid

The article studies the molecular composition of dental biofilm in healthy people and patients with multiple caries lesions during several stages of exogenous and endogenous preventive measures. The observed changes in the IR spectra registered during different stages of the experiment indicate a lack of balance between demineralisation and mineralisation of hard tissues resulting from different absorption mechanisms of agents applied exogenously and endogenously. All the observed changes result from the difference in the microbiota in healthy patients and patients with caries, as well as the difference in the microbiota caused by the impact of preventive agents on biofilm
