Abstract
Mariakrite is a new mineral in the hydrotalcite supergroup, and a member of a novel family of layered double hydroxides, or LDH. It is the first reported LDH with dithioferrate, [Fe3+S2]− in the role of an interlayer anion, the first cementitious layered Ca-aluminate (AFm phase) intercalated with sulfide, and the first sulfide-intercalated LDH with completely solved crystal structure. Mariakrite was discovered in late hydrothermal assemblages confined to pyrometamorphic lithologies of the Hatrurim Formation, in the Negev Desert on the Israeli side of the Dead Sea. The mineral forms saber-like crystals up to 2 mm long, 0.1 mm wide and 0.5 to 2 μm thick, residing in millimeter-sized cavities within larnite-jasmundite-brownmillerite rock. Associated minerals are katoite, portlandite, kuzelite and hydrocalumite. Mariakrite has a purple-brown color with semimetallic luster; in transmitted light, it is transparent green-grey. The crystals are flexible and elastic. Mohs hardness is 3–3.5. Calculated density is 2.005 g cm−3. In reflected light, the mineral exhibits extreme pleochroism, from grey to red-purple. Anisotropy is very strong. Reflectance values for 4 wavelengths recommended by the IMA Commission on ore mineralogy [in air, R1/R2, % (γ, nm)]: 5.0/5.2 (470), 6.3/2.3 (546), 6.7/1.8 (589), 6.6/17.6 (659). Mariakrite is triclinic (pseudo-pseudomonoclinic and pseudo-trigonal), space group P1¯, a 5.7107(2), b 9.9952(4), c 10.9095(4) Å, α 98.678(3), β 90.100(3), γ 90.019(3) °, V 615.58(4) Å3, Z = 1. The 7 strongest lines of X-ray powder diffraction pattern are [d in Å (I)(hkl)]: 10.83(100)(001), 9.90(39)(010), 5.42(75)(002), 3.96(22)(0− 22), 3.523(19)(−112), 2.856(37)(130), 2.400(23)(132). The crystal structure, solved and refined to R1 = 0.045 for 2379 independent observed reflections, consists of hydrocalumite-type LDH layers [Ca2Al(OH)6(H2O)2]+ intercalated with the iron disulfide chains. The latter are composed of edge-sharing tetrahedra [FeS4] forming dithioferrate (III) anion, [Fe3+S2]−. The hydrocalumite-like layers and sulfide chains are linked via the system of O–H···S hydrogen bonds. Chemical composition (electron microprobe, wt.%, H2O based on the structural data) is: CaO 27.75, K2O 1.85, Al2O3 13.93, Fe 14.23, S 16.94, H2O 23.88, Total 98.58. The empirical formula calculated on the basis of Σ(Ca,K,Al,Fe,S) = 12 apfu is (Ca3.73K0.30)Σ4.03Al2.06(OH)12.18Fe1.92S3.99·3.91H2O, corresponding to the ideal formula [Ca4Al2(OH)12(H2O)4][Fe2S4]. Mariakrite is the first example of dithioferrate in which disulfide chains have no contacts with cations or anions, being suspended between hydroxide layers via the system of hydrogen bonds. Therefore, the mineral might represent the near-ideal model for the study of physical and chemical properties of isolated quasi-one-dimensional dithioferrate chains.

ABSTRACT
Weirs are designed to stabilize rivers, grade control, and raise upstream water levels. The failure of these structures is primarily due to local scour at the structural site. Consequently, an accurate estimate of the likely scour depth at the structure is critical for weir design safety and economy. This study proposes machine learning models for scour depth prediction at submerged weirs by introducing advanced gradient boosting algorithms, namely gradient boosting (GB), categorical boosting (CatBoost), adaptive boosting (AdaBoost), and extreme gradient boosting (XGBoost). A database consisting of 308 cases was collected for model calibration and evaluation. The results demonstrate that the GB algorithm is very accurate, with coefficients of determination of 0.99610 and 0.96222 for the training and testing datasets, respectively. The GB model outperforms other developed models, such as support vector regression, decision tree, and ridge models, in the literature. A sensitivity analysis study has determined that the morphological jump parameter is the most significant factor, whereas the normal flow depth on the equilibrium bed slope is the least significant factor in predicting the ds under the submerged weir.

The relationship between a dog and a person as a predictor of the occurrence of behavioral disorders. Currently, the issue of problematic behavior of companion dogs is becoming particularly relevant. The most important reason for the insufficient adaptation and socialization of dogs in society, ineffective training, and a decrease in the quality of life of animals is the lack of a scientifically based concept for identifying the causes of behavioral disorders and their elimination. It is noted that it is necessary to study early socialization, the formation of the type of attachment between the dog and the owner as a predictor of possible anxious or aggressive behavior.
The purpose of the study. The study of behavioral disorders in domestic companion dogs. The article provides an analysis of 132 modern studies on various aspects of problematic behavior.
The occurrence and impact of behavioral disorders in dogs. There is a correlation between aggressive and anxious behavior of dogs with the type of attachment and the way of communication with the owner. The neuroticism of the owner and the avoidant type of attachment are one of the key factors in the formation of behavioral signs of anxiety in a dog. For animals with anxiety disorders, a decrease in life expectancy, an increase in the frequency of aggressive manifestations, and a violation of communication with the owner are shown, which ultimately leads to a decrease in the quality of life in the "owner-dog" dyad.
Identification of behavioral problems in dogs. Biochemical methods for the diagnosis of behavioral disorders are based on the analysis of the concentration of serotonin, cortisol, oxytocin and dopamine in biological fluids and dog hair. Physiological methods of diagnosing behavioral disorders are based on the assessment of ECG and thermometry. Surveys of dog owners and instrumental and behavioral test samples are also used.

Introduction. A perceptual set is a specific psychological mechanism that shapes the perception of objects based on prior experience, current goals, and the conditions of perception. Previous studies have shown that both realistically different and illusorily distorted objects can create a perceptual set effect in adults.
The aim of this study is to experimentally verify the formation of the perceptual set effect in children using the Müller-Lyer and Ponzo illusions, in comparison with the presentation of segments that differ in length.
Methods. The sample consisted of 26 children with an average age of 6.45 years. The stimulus material was presented in three series: real-different segments (with actual size differences), the Ponzo illusion, and the Müller-Lyer illusion. Each series included 10 setup stimuli and 5 pairs of equal segments to assess the perceptual set effect. Prior to the main experiment, all children underwent diagnostics of visual perception maturity and were divided into two groups based on their level of visual perception constancy maturity.
Results. Statistical analysis of the experimentally obtained data revealed a perceptual set effect in children with a high level of visual perception constancy maturity, observed in both the series with real-different segments and the Müller-Lyer illusion. Children with low constancy maturity did not exhibit a perceptual set effect. The Ponzo illusion did not produce a perceptual set effect in either group of children.
Discussion. The results obtained should be regarded as new evidence supporting the idea that the Ponzo and Müller-Lyer illusions belong to distinct categories of illusions.

Introduction. This paper presents the results of a study of the relationship of the size (the total number of group members and the number of informal subgroup members) and gender and age composition of work groups with the extent to which they implement functions in relation to group members. The functions include (1) creating possibilities for realization of individual goals and meeting individual needs; (2) protection from external social threats; (3) informing (providing information to) members; (4) educating members; (5) adaptation of (providing adaptive capacities to) members; and (6) providing control and regulation. Methods. The study was conducted in 49 departments of companies with 4 to 14 employees (n = 290; 75.35 % women and 24.65 % men aged 21–70 years). In the first stage of the study, the Group Profile computer program was used, which included a formalized algorithm for identifying informal subgroups in the group. In the second stage, a printed form of a questionnaire on group functions related to group members was used. Data were analyzed using descriptive statistics, the Pearson Chi-square test, the nonparametric Mann-Whitney U-test, and the bias-corrected bootstrap. Results. The number of members included in informal subgroups (in relation to total group size) has a direct positive effect, while the total group size has an indirect negative effect (mediated by the number of group members in subgroups) on the functions that work groups carry out in relation to group members. None of the functions correlated with the gender-related heterogeneity of groups. However, the function of providing information to members negatively correlated with the age-related heterogeneity of groups. Discussion. This study presents the first step toward understanding the antecedents of the functions that work groups implement in relation to group members. The results obtained can be used by managers and psychologists to solve practical problems. Further studies will investigate group composition based on other properties and group socio-psychological characteristics as antecedents of the functions that work groups carry out in relation to group members.

Introduction. In a person's life, a traumatic life situation or incidental life experience may lead to various dysfunction on both physiological and psychological levels. The aim of the study is to identify the specifics of self-esteem, self-attitude and attitudes towards life in people who were physically injured as a result of a traumatic event. Methods. The study involved 220 men with a variety of physical injuries and traumas. We used Sacks Sentence Completion Test, SSCT by J. Sacks, S. Levy and The Twenty Statements Test (TST) ("Who Am I?") by M. Kuhn, T. McPartland. Results. Individuals who had undergone amputations showed normal, healthy levels of self-esteem, while individuals with severe, life-threatening body injuries showed low levels of self-esteem. There are statistically significant differences in self-attitude and attitude towards different aspects of life among people with varying degrees of physical traumas and injuries. Men with severe, life-threatening body injuries showed the most pronounced feelings of guilt; they also had flashbacks to past experiences within the experience of the traumatic situation. Discussion. Researches of self-esteem and self-attitude in individuals who have suffered various physical injuries and traumas confirm our results. Studies confirm that people with injuries of moderate and severe forms have different attitudes towards various aspects of their lives and specifics of guilt feeling formation compared to people who have experienced amputation surgeries.

Introduction. The article presents the development of express-methodology for diagnosing the psychological component of rehabilitation potential of persons who received disability during combat operations and special military operations. Based on the experience of diagnostic examinations of other components of rehabilitation potential (psychophysiological, professional and pedagogical, social and environmental), the indications and indicators for complex express-diagnostics were selected, the optimized structure of which formed the basis of the corresponding methodological tool. Cognitive, affective and conative representants were identified as structural elements of the psychological component of the rehabilitation potential of the personality.
Methods. For the purpose of approbation and formalization of the methodology, 345 respondents aged 18 to 42 years, 54% female and 46% male, took part in the study. The methods used as a basis for validation were the test "Assessment of personality adaptability" (S.I. Yakovenko), J. Endicott quality of life assessment scale, I. Schuller, A. Komuniani optimism and activity scale, "Self-assessment of conflict" test (A.Y. Antsupov, A.I. Shipilov), "Resilience test" by S. Muddy, express-diagnostics of cognitive abilities (G.S. Nikiforov).
Results. The obtained instrument was tested for reliability, the optimal number of indicators presupposes 22 items. Based on confirmatory factor analysis, they are combined into a three-factor model, which has high values ​​of verification indicators of compliance of this model with the data. High indicators of convergent and divergent validity were obtained by comparing the data with the results of existing standardized methods.
Discussion. Three factors in the model of the psychological component of the rehabilitation potential of the individual are represented by the factor "Behavior", including "Adaptability", "Quality of life" and "Optimism", the factor "Emotionality", including "Intrapersonal conflict" and "Neurosensory stability" and the factor "Cognition", including "Logic", "Memory" and "Attention". The levels of assessment of both individual factors and the complex indicator of the psychological component of the rehabilitation potential of the individual are identified, which allows us to speak about the suitability of this tool for use by specialists when working with individuals with disabilities acquired during combat operations and special military operations.

Mixed Nanoaggregates: A Fluorescence Spectroscopy Study
Authors: Rocha Kaio César Antunes , de Arruda Brasil Maria Carolina Oliveira , Cilli Eduardo Maffud , Salay Luiz Carlos 
Published: January 2025

Introduction:
Tritrpticin (TRP3) is a peptide belonging to the cathelicidin family and
has a broad spectrum of antimicrobial activity. However, this class of biomolecules can be easily
degraded in the body, making it necessary to use an efficient transport system. The ability to form
stable nanostructures from the interaction of glycyrrhizin saponin with the pluronic polymer F127
was demonstrated, forming mixed biopolymeric micelles, highly promising as drug carriers.

Objective:
The present work sought to understand the physicochemical interaction of the antimicrobial
peptide TRP3 with the mixed polymeric micelle made from pluronic F127 and the saponin
glycyrrhizin.

Methods:
The interaction of tritrpticin with mixed nanostructured micelles was evaluated through
fluorescence spectroscopy and fluorescence quenching with acrylamide. The experiments were
performed at room temperature (25 ± 1°C), adopting an excitation wavelength set to 280 nm and
emission between 300 and 500 nm, with a slit of 5 nm.

Results:
The interaction of the cationic peptide tritrpticin with the mixed biopolymeric micelles
was observed through the blue shift of the fluorescence emission to shorter wavelengths, proving
the change of tryptophan to a more hydrophobic environment. Through the fluorescence suppression
technique, it was possible to indicate the location of the peptide in the mixed micelles, proving
tritrpticin to be partially inserted inside them.

Conclusion:
It was concluded that tritrpticin interacted with mixed nanostructured micelles, forming
a promising system for biotechnological applications.
Clomipramine-Induced Urinary Retention in an Adult Male - A Case Report
Authors: Mehta Priya , Sapovadia Pooja , Purohit Bhargav 
Published: January 2025

Background:
Clomipramine, a Tricyclic Antidepressant (TCA), is known for its efficacy in treating Obsessive-compulsive Disorder (OCD). However, it is associated with several side
effects, including urinary retention. This case report discusses the case of a 20-year-old male with
OCD who developed urinary retention following clomipramine administration.

Case Representation:
A 20-year-old male with a one-year history of OCD with psychotic features
was admitted to SIR-T Hospital, Bhavnagar, due to worsening symptoms. He was prescribed
clomipramine along with other psychotropic medications. On the 16th day of hospitalization, the
patient experienced acute urinary retention, necessitating catheterization. Clomipramine dosage
was subsequently reduced, resulting in the resolution of urinary retention. The patient was
discharged after 29 days with no further urinary complications.

Discussion:
The causality assessment suggested a probable link between clomipramine and urinary retention, supported by the Naranjo Scale, WHO-UMC criteria, and literature. The anticholinergic properties of clomipramine likely contributed to the condition. Despite its side effects,
clomipramine remains a valuable treatment for OCD, requiring careful dose management to mitigate adverse effects.

Conclusion:
Clinicians should be vigilant for urinary retention in patients receiving
clomipramine, especially at higher doses. Regular monitoring and dose adjustments are crucial for
managing this side effect without compromising the therapeutic benefits for OCD.

Published: January 2025

Background
Sub-Saharan Africa faces a significant burden of mental health challenges, including depression and anxiety, particularly among vulnerable populations such as women and individuals living with HIV. This study proposes a machine learning-guided Lyric Analysis Peer Support Intervention (LAPSI) to predict psychological distress and inform interventions. The study utilizes machine learning to generate risk profiles, presenting an innovative application in identifying psychological distress risk factors for developing targeted interventions.

Objective
The objective of this study is to utilize machine learning models to generate risk profiles that predict psychological distress among HIV-positive and HIV-negative populations and to use these profiles to guide thematic development for LAPSI, ensuring confidentiality and informed consent.

Methods
The study aims to leverage machine learning algorithms such as Logistic Regression and Random Forest to generate risk profiles and to analyze demographic, socio-economic, and psychological factors, including HIV status, age, education, and employment. Introducing a novel application of machine learning in the identification of psychological distress risk factors for intervention development while adhering to ethical standards for handling sensitive data like HIV status. Prior to data collection, ethical approval will be obtained, ensuring participant confidentiality and informed consent. Themes generated from the risk profiles will inform song selection and peer support intervention for LAPSI.

Results
The machine learning models are expected to highlight education, employment status, and marital status as critical predictors of psychological distress. Geographical and demographic variables, such as district and age, are hypothesized to play a significant role in predicting distress among both HIV-positive and HIV-negative cohorts.

Conclusion
This study posits that machine learning models will provide actionable insights into predicting psychological distress, enabling targeted interventions through LAPSI. This short communication argues for integrating LAPSI into health policies and calls upon health policy actors to recognize its potential in addressing the mental health crisis in Sub-Saharan Africa, advocating for partnerships with local communities, healthcare providers, and mental health advocates to tailor and implement this intervention effectively.
