Background
Using the multiphase optimization strategy (MOST) framework, we aimed to identify a feasible, acceptable and optimized set of mHealth-delivered behavioral strategies for reducing recreational sedentary screen time (rSST) by at least 60 min/day.
Methods
Eligible participants were 23–64 years old and had high rSST (> 3 h/day). We used a full factorial (23) design in which participants received a “core” mHealth application and were randomized to combinations of three components (on vs. off): LOCKOUT: rSST electronically restricted; TEXT: rSST reduction prompts; and EARN: rSST through physical activity. rSST was assessed at baseline and at 8 and 16 weeks of age via an integrated measure of sedentary time and screen time. We used a linear mixed effect model to test the change in rSST for the three intervention components and their interactions.
Results
A total of 82% of the randomized participants (N = 110) were female, with a mean ± SD age of 41 ± 11.7 y and a BMI of 29.7 ± 7.8 kg/m2, and their mean (95% CI) rSST was 184.7 (172.8, 196.5) min/day at baseline. The expected difference (baseline vs 16 weeks) in rSST was greatest for the intervention versions with a core, LOCKOUT, TEXT, & EARN (-125.7 [-172.0, -79.3] min/day) at the “on” level. The participants were satisfied with the study and found the app helpful in reducing rSST (> 94%). Technical issues resulted in 20% being somewhat dissatisfied with the app.
Conclusions
We identified several promising intervention versions that exceeded our optimization objective. The intervention version that included core, LOCKOUT, TEXT, & EARN components “on” was efficacious, feasible and acceptable and should be used to test the effect of rSST reductions on health outcomes.

Is the posterior malleolus automatically reduced after fibula fixation? A prospective Computed Tomography study
Authors: Rozis Meletis , Mason Lyndon , Evangelopoulos Dimitrios-Stergios , Stavridis Eleftherios , Pneumaticos Spyros
Published: February 2025

Introduction:
Ankle fractures are quite common, with significant rates of post-traumatic arthritis, particularly in cases involving posterior malleolus malreduction. The traditional understanding of indirect reduction through ligamentotaxis following fibula fixation has been frequently questioned, as it is believed to lead to high rates of malreduction. We conducted a prospective Computed Tomography study to assess the quality of posterior malleolus reduction in patients treated without direct fixation of the fragments.
Materials and Methods
During the study period from 2018 to 2023, 71 patients with ankle fractures and no direct fixation of the posterior malleolus underwent postoperative computed tomography of both ankles. Measurements of the injured sites were compared to each patient’s normal ankle to evaluate the reduction quality of the posterior malleolus fragments reduced through ligamentotaxis. Fragments with a translation of less than 2 mm were deemed anatomically reduced.
Results
In our patient cohort, 21 patients had a Mason type 1 fracture, 19 had a Mason type 2A fracture, 8 had a Mason type 2B fracture, and 21 patients had a Mason type 3 fracture. Indirect fixation led to an anatomical reduction in 91.3% of Mason type A fractures, 54.5% of Mason type 2A fractures, 31.25% of Mason type 2B fractures, and 76.2% of Mason type 3 fractures. Patients with a Mason type 2 fracture displayed the greatest heterogeneity in the quality of reduction. Concerning the inherent incisura anatomy, the rotation of the incisura was significantly affected, resulting in a decrease in the normal notch retroversion.
Conclusion
Indirect fixation of the posterior malleolus through ligamentotaxis has significantly unpredictable results, which are directly connected to the fragment morphology type. Preoperative Computed Tomography is essential in those cases, with direct fixation deemed mandatory in most cases. Further studies that evaluate the clinical importance and true impact of malreduced posterior malleolar fragments on ankle joint function are crucial to safely interpret our results.

Published: February 2025

Introduction:
Pediatric cardiology fellowship programs in the United States (U.S.) follow the Accreditation Council for Graduate Medical Education (ACGME) guidelines, requiring scholarly activities for completion. However, detailed data on research experiences within these programs are scarce. This study sought to describe the state of research training and exposure in U.S. pediatric cardiology fellowship programs.
Methods
An electronic survey was sent to 350 pediatric cardiology fellows across the U.S. The survey assessed demographics, availability of research training resources, perceived barriers to research, expected research output, and satisfaction with research exposure. Fellowship programs were classified by size: small (1–5 fellows), medium (6–9 fellows), and large (10 + fellows). Statistical analyses included comparisons and logistic regression.
Results
Most respondents (89%) agreed with the statement: “I have been encouraged to pursue research training and experiences during my fellowship.” However, only 31% agreed with the statement: “I am satisfied with the training on research methodology and statistics provided by my fellowship program.” Commonly endorsed barriers to completing research projects included lack of statistical support (37%), lack of protected time for faculty to support fellow research (56%), lack of a formal research curriculum (38%), and lack of funding for fellow research (26%). Research training and experiences differed by program size, with larger programs providing more protected time and greater encouragement for research, while smaller programs were more likely to rely on online resources.
Conclusion
Despite strong encouragement for research, satisfaction with research training in pediatric cardiology fellowship programs is limited. Addressing barriers such as statistical support, protected faculty time, and formal research curricula could enhance the research experience and outcomes for fellows.

Reducing starting depth in the transient electomagnetic method
Authors: Pospeev A. V. , Buddo I. V. , Absalyamova D. F.
Published: February 2025

The article considers the possibilities of reducing the starting depth of studies using the near-field transient electromagnetic method by determining the effective transmitter-receiver offset. The solution of this problem is relevant due to the need to apply inductive electromagnetic exploration using ungrounded multi-offset templates in the climatic conditions of the Arctic. Optimization of the transient electromagnetic method technology in the far and near-field zones will expand the range of explored depths, which is extremely important for studying the accumulations of difficult to recover hydrocarbons located at depths from the first tens of meters to 3–4 km. To solve this problem for a half-space model, mathematical modeling of the transient electromagnetic signals was carried out taking into account the geometric spacing of soundings, which allowed to determine the effective signal offset by solving the inverse problem. On the basis of the mathematical modeling performed, a nomogram of the effective offset dependence on the transmitter loop size and template geometric spacing has been built. The use of the results obtained makes it possible to provide the actual starting depth of electromagnetic soundings from 7–10 m, which significantly increases the range of the studied depths due to the interpretation of the far-field sounding zone.

Published: February 2025

In this work, we present a voltammetric study on 14 different food matrices to address a gap in the literature regarding the absence of data on the values of anodic peak potential (Epa), cathodic peak potential (Epc), anodic peak current (Ipa), and cathodic peak current (Ipc) in these matrices. The results were organized into two tables covering Epa, Ipa, Epc, and Ipc parameters. Various extraction media and two testing techniques: differential pulse voltammetry (DPV) and square wave voltammetry (SWV) were explored for each matrix studied. These findings are expected to contribute to the initial stages of the development of analytical voltammetric tests in the presence of food matrices, elucidating the matrix signal behavior at different pH values and media, as studies indicate significant differences in Ep and Ip values of food matrices under different analytical conditions. Furthermore, the calculated electrochemical parameters values demonstrated the presence of antioxidant compounds in all analyzed foods, suggesting that these foods may serve as dietary sources of natural antioxidants with potential health benefits.

The article is devoted to the study of mental structures’ role in the regulation of mental states in the dynamics of changes in the intensity of situations. The conducted research based on our conceptual model of mental states’ regulation, which based on systemic positions and concepts of self-organization. The purpose of the study is to identify the nature of the relationships between methods of self-regulation, mental structures and the effectiveness of mental states’ self-regulation in the dynamics of activity from everyday situations to stressful ones. The study carried out during three types of activities in three groups: consisting of students (34 people), athletes (35 people) and office workers (30 people), 47 men, 52 women, the average age — 23 years, 99 people. We used methods for diagnosing mental structures (reflection, self-system, life-meaning orientations), methods of self-regulation and regulatory properties, as well as mental states and the effectiveness of their regulation. The study carried out in several stages: at the first stage, mental states, effectiveness and methods of their regulation in everyday situations we diagnosed in each group, at the second stage, the same in a tense situation of activity. The mental structures of the respondents diagnosed regardless of the activity situations. As a result, found that, regardless of the specifics of the activity, the structures of mental regulation contribute to an increase in the number of positive states (concentration, joy, involvement) and a decrease in negative states (anger, anxiety, fatigue, boredom). Shown that from every day to stressful situations of activity, the number of relationships between mental structures and the effectiveness of self-regulation of states decreases, which is more typical for sports activities and to a lesser extent for educational and work activities. An increase in the number of negative states in stressful situations of activity, along with a decrease in the involvement of mental structures in the regulation of mental states, may indicate the key role of the latter in the system of state regulation.

Two species, Trichia sikhotensis and T. subfusca, are described and illustrated in
detail. Trichia sikhotensis is a new species to science discovered in the Russian Far
East. It is characterized by a long straight stalk, globose sporotheca, peridium with
blurry spots, and smooth capillitium with rather long elater tips. It is morphologically
similar to the European species T. ambigua. Trichia subfusca is a very rare and often
misidentified species. We identified specimens from the Altai Mountains as such
during the revision of Trichia spp. specimens from the LE Fungarium. The most
important diagnostic feature of this species, in addition to short elater tips and evenly
colored peridium, is a smooth area on the spores, lacking any ornamentation. This
feature is present in both our specimens and the syntype of T. subfusca from the
Kew Herbarium (K), studied earlier by Jan Rammeloo, which we designate here
as a lectotype. The phylogenetic positions of both species were determined by a
multigene analysis.
EXPERIMENTAL LEGAL NORM: DOCTRINE, PRACTICE, LEGAL WRITING
Authors:   Penza State University, V. Margaryan Arsen
Published: February 2025

Background. Each state strives to create a high-quality, effective system of legal regulation. It is very difficult to achieve this by traditional means in the context of dynamically developing social relations. In this regard, in order to evaluate and validate specific approaches to influencing public relations and testing non-standard techniques, public authorities actively resort to experiments, the basis of which is an experimental legal norm. The main aim of the study is to define the concept, doctrinal concepts of perception of this type of special legal norm, to identify problems of technical and legal consolidation and practical implementation, to suggest ways to solve them. Materials and methods. Through using the formal legal method in the study, the author defines and proposes the concept of “experimental legal norm” and outlines its features. The source, normative and empirical base of the article includes Russian and foreign doctrinal and normative legal materials (monographs, normative legal acts, law enforcement acts and interpretation of law), as well as statistical data on using experimental means of legal influence. Results. The importance of using an experimental legal norm to improve the quality of legislation and the effectiveness of regulating public relations is emphasized. The necessity of using all the technical and legal tools to correctly set the goal of experiments in general and to introduce and implement the experimental norm in particular is reasoned. Conclusions. The au-thor proves that an experimental legal norm can act as a compromise model of legal regulation based on a scientific and methodological approach and testing of the chosen approach in a limited area, within the defined time limits and across the specified list of subjects. To achieve the set goals of legal experiments, rulemaking should apply the available technical and legal arsenal: from general (structuring the rule of law and the entire normative legal act) to special (using normative clauses, blank structures, etc.) means.

Background. The relevance of the study is associated with the importance of exploring the interaction of the state and civil society structures in a changing public space. Under the global information impact on society, another relevant topic is the attitude to the state images and state symbols among young people, as well as their consideration in the context of forming state identity in modern society. The study is devoted to creating a holistic view of the state identity of student youth, revealing connections in building a social model of the value and identifying aspects of the perception of the country in forecasting and making effective decisions to ensure sustainable development and prosperity of the Russian Federation. Materials and methods. The study of state identity is based on surveys among the students of Penza State University, as well as sociological tools and traditional scientific methods of systematic and structural-functional analysis of sociological research data presented by the All-Russian Public Opinion Research Center and the Public Opinion Foundation. Results. The practical significance of the study is determined by the relevance of the obtained results in the activity of regional public authorities. Conclusions. The state symbols are an important factor in establishing state civic identity and consolidating youth society. The study may serve as a basis for implementing state youth policy in order to form civic identity.
RUSSIAN COSMISM AND POST-REVOLUTIONARY RUSSIA THROUGH THE LENS OF SILVER AGE LITERATURE AND HILOSOPHY: I.A. BUNIN
Authors:   St. Petersburg State Agrarian University, G. Kovalenko Natalya
Published: February 2025

Background. The historical philosophical approach to analyzing the theoretical and artistic-aesthetic heritage of the first Russian Nobel Prize winner in literature, writer Ivan Alekseevich Bunin, is interesting for the modern reader not only for its philosophical component, but also for its literary factuality, which allows understanding his prose as classic for the preservation of the heritage of Russian lyrics. I.A. Bunin is a cosmist philosopher and for him mankind is a part of the natural world, a force of its nature comparable to the geological force (academician V.I. Vernadsky). Therefore, I.A. Bunin’s philosophical ideas, expressed in the artistic and literary form, constitute the research aim of this paper, devoted to Russian cosmism through the lens of Silver Age literature. Materials and methods. The set aim is achieved through studying I.A. Bunin’s literary work, in particular his prose of the early 20th century as one of the cultural figures of the Silver Age. The peculiarity of the work of the Russian writer of this period is that I.A. Bunin is a principal supporter of literary individualism, irreducible to the ideology of the main trends of the time: symbolism, acmeism, futurism. The interest of the Silver Age creators in the religious component of human life and society did not bypass him, but it resulted in a section of fascination with the philosophy of pantheism and the accentuation of the Christian Orthodox aspect in the world perception and worldview of the Russian writer. Results. In addition to historical and philosophical material, the article explores such a direction of I.A. Bunin’s literature as his comprehension of the tragic realities of the Second and Third Russian Revolu-tions of 1917. As a social thinker, I.A. Bunin characterises this time with the epithet ‘the days of darkness’. Conclusions. The study of the stated topic enables drawing the following conclusions: the creativity and philosophical position of the writer underwent a long evolution: from the idealisation of the Russian people to the idea of the ‘power of the crowd’ in revolutionary Russia; from a worldview in the vein of Russian cosmism to the religious philosophy of pantheism and the idea of world harmony; the creative destiny of I.A. Bunin is indicative in terms of the absolutisation of the individuality of the creator-writer and in this we see a significant similarity with the position of the Silver Age poetess Marina Tsvetaeva.
GLOBALIZATION AND ITS IMPACT ON THE PUBLIC LEGAL CONCEPT AND GENESIS OF STATE SOVEREIGNTY
Authors:   Penza State University, D. Gned Anastasia
Published: February 2025

Background. In recent years, due to the upsurge in international tensions and the presence of military conflicts against the background of the third wave of globalization, state sovereignty tends to strengthen. In this regard, the article, which aims at studying the impact of globalization on the genesis and public legal concept of state sovereignty, seems very relevant. Materials and methods. The materials for this article are scientific works of Russian and foreign authors on the topic under study, legislative acts of various countries, international treaties and agreements. In the process of study the author combines the dialectical, systemic, historical analysis with subsequent synthesis, as well as historical and legal analysis. Results. In the process of globalization there are three waves: 1) 1870–1914; 2) 1950–1980; 3) began after the end of the bipolar world (1991) and lasts to the present day. The first wave of globalization virtually did not affect state sovereignty. The second wave initiated its transformation, and the third one led to the dilution of the concept of state sovereignty up to the conclusion of international agreements authorizing “humanitarian intervention”. Nowadays, due to the increasing international tensions and military conflicts, despite the ongoing globalization, there is a tendency to strengthening state sovereignty and returning its public legal concept to the classical canons. Conclusions. At present, against the backdrop of the upsurge in international tensions and military conflicts, the most economically developed countries in the world are striving to reinforce their state sovereignty. A new and extremely important aspect of state sovereignty in the context of confrontation has emerged, namely digital sovereignty. The trend towards returning the public-law concept of state sovereignty to classical canons is detected.
Exploring the Understanding and Triage Practices of Midwives Working in District Hospitals of Mpumalanga Province, South Africa
Authors: Ngwenya Mxolisi Welcome , Muthelo Livhuwani , Rasweswe Melitah Molateo , Mothiba Tebogo Maria
Published: February 2025

Background

Triage in healthcare involves the process of prioritizing patients in their level of urgency and also the allocation of resources. However, triage has been used mainly in emergency departments around the world. Only in recent years have triage systems been gradually implemented in maternity units. It is a relatively new concept in maternity units and its landscape is not properly understood.

Objective

The study aimed to explore the understanding and practices of triage by midwives working in the labour wards of selected district hospitals in Mpumalanga province, South Africa.

Methods and Materials

A qualitative, exploratory, and descriptive research design was used to explore the practices and understanding of midwives regarding labour ward triage. A purposive sampling method was used to select experienced midwives who work in labour wards. The sample size was directed by data saturation, reached at the 20th participant. The data were then analysed using thematic analysis. Trustworthiness was ensured through the Lincoln and Guba criteria (1985).

Results

Two themes emerged regarding midwives' understanding and practices of triage namely, a nuanced understanding of triage in the labour wards and a description of existing triage practices of midwives. The themes were interpreted into five sub-themes.

Conclusion

The study revealed that the absence of triage systems in maternity units delays obstetric care, contributing to poor maternal and perinatal outcomes and rising litigation in South Africa. The findings call for the National Department of Health to strengthen triage policies and guidelines and suggest co-designing a triage system with midwives to enhance implementation and feasibility.

Authors: Praditya Al Farriz Sandro , Rahardjo Bambang Tri
Published: February 2025

Coffee (Coffea sp.) is one of the leading commodities in the Indonesian plantation sector. The low productivity of coffee plants can be caused by several factors, one of which is the loss caused by the Coffee Fruit Borer (CFB) Hypothenemus hampei Ferr (Coleoptera: Scolytidae). This research aims to study the flowering phenology of coffee plants and the influence of different plant varieties on the phenology of the CFB. The research was conducted using an exploratory survey method and laboratory analysis. Based on the results, the phenology of H. hampei in each phase has different characteristics, and it was found that there is overlap in the phenology phases of coffee fruit, which causes the life cycle of H. hampei to remain uninterrupted throughout the year. The highest population of H. hampei was found in the BGN 371 compared to the BP cultivar.

Published: February 2025

Background

Nonsuicidal self-injury (NSSI) is a major public health problem leading to psychological problems in adolescents and young adults, similar to disorders such as depression and anxiety.

Objective

The aims of this study were to investigate (1) the interaction between BMI and socioenvironmental factors (including chronotype and mental health) that contribute to NSSI, and (2) whether self-esteem plays a mediating role in this association.

Methods

From May to June 2022, the multistage cluster sampling method was used to sample college students in four grades, including freshmen and seniors. The baseline participants were followed up 6 months later, excluding those who did not qualify, and the participants included 1772 college students. Socioenvironmental factors (chronotype/mental health), self-esteem, and NSSI were measured using a questionnaire. Multivariate linear regression models and chi-square analysis were used to evaluate the linear relationship between BMI, socioenvironmental factors, and self-esteem and the NSSI status. We use a process approach (mediation-moderation analysis) to explore the complex relationships between these variables.

Results

The mean age of the participants was 20.53 (SD 1.65) years at baseline. A significant association was revealed, suggesting that a high BMI (β=.056, 95% CI 0.008‐0.086, P=.018) was associated with a higher NSSI. There was also an interaction among BMI, socioenvironmental factors, and NSSI. Socioenvironmental factors played both moderating and mediating roles in the relationship between BMI and NSSI, whereas self-esteem only played a mediating role.

Conclusions

Paying attention to factors such as overweight and obesity is important for early BMI control to identify other potential risk factors for NSSI and to evaluate how self-esteem can be improved considering multiple perspectives to improve the effect of BMI on NSSI in adolescents.

Authors: Kituyi Geoffrey Mayoka
Published: February 2025

UNSTRUCTURED

The purpose of this study was to develop and test a model that can be used to promote the learning of positive mental health amongst social media users while engaged on social media platforms.

A cross-sectional research design was adopted with a positivist epistemology. Data were collected from 450 social media users Uganda, Cameroon and Nigeria. Descriptive statistics, confirmatory factor analysis and structural equation modeling methods were used to analyze data.

The proposed model was tested and found to be fit. The obtained =8.653 is below 20, /DF=1.442, P=.194 is above the recommended minimum of 0.5. The GFI=.993, AGFI=.968, NFI=.983, RFI=.940, IFI=.995, TLI=.981, and CFI=.994 were all above the threshold of 0.9. The obtained RMSEA of .035 was also far below the recommended maximum threshold of 0.08 for a model to be fit. Based on these indices, we conclude that the proposed model explains mental health of social media users.

Published: February 2025

The goal of the article is to track down the giant tabular iceberg D28 trajectory from its calving in September 2019 from Amery Ice Shelf until reaching the western part of the Weddell Sea in March 2023 and to present characteristics of the iceberg state and movement, derived from satellite radar data. The Maximally Stable Extremal Regions (MSER) method, which used as an imagery recognition technique for time-dependent visual conditions, has been applied to automatically identify iceberg’s positions. On the basis of the Sentinel-1A/B SAR data during 1,275 days, timeseries of D28 location, spatial orientation, mass, area, moment of inertia, linear and angular velocity, kinetic and rotational energy, grounding location are presented. D28 dynamics display strongly pronounced regionality, generalized into the three distinct sections of its drift along the Antarctic coast. These sections are in good agreement with existent concepts in the oceanographic literature, concerning the system of Antarctic Slope Current / Antarctic Slope Front.

The present invitro study carried out with eleven blackgram genotypes including T-9 used as check were collected from NBPGR regional centre Hyderabd and ICAR-CRIDA Hyderabad respectively. Seeds that were healthy and uniformly sized were surface sterilized for two to three minutes using 0.1% mercuric chloride (HgCl2) before being thoroughly washed with distilled water. The sterilized (10) seeds were sown in petri plates with moistened germination paper and various water potentials, namely, 0.0 (control), 5%, 10%, 15%, 20%, 25% and 30% of PEG 6000 in 100 ml of distilled water. The ANOVA results revealed sgnificant variability due to treatment, genotype and treatment verses genotype for the trait seed grmination at all the percentage of PEG 6000 studied. The results showed that among eleven genotypes IC426766 and IC382811 recorded higher germination percentage at higher PEG concentration and upto 20% PEG very lower percentage of germination was observed. It indicates that the variety IC426766 with hold the water even at higher concentration and showing water stress condition.
Interrogatório de suspeitos: a entrevista investigativa como técnica de redução de falsas confissões induzidas por sugestionabilidade
Authors: Gomes Giovanna Paula Vieira Oliveira , Lopes Ederaldo José
Published: February 2025

False confessions occur when someone confesses to a crime they didn't commit. They can be voluntary or involuntary and result from factors related to personal motivations or the way the confession is obtained. Involuntary confessions can be induced by interrogation techniques considered accusatory, through psychological manipulation, such as the Reid method. The presumption of guilt tends to provoke interrogative suggestibility, especially with more vulnerable groups, namely adolescents and people with mental disorders or cognitive deficits. This causes damage in relation to obtaining reliable information since the true content of memory may be unrecoverable with the use of inappropriate techniques. In view of this, investigative interview techniques have been developed to change the accusatory mentality towards the search for information, as proposed in the PEACE method. Thus, the question arises: which aspects of the investigative interview can minimize or avoid interrogative suggestibility with criminal suspects? To achieve this, the study discusses the accusatory approach to interrogation, identifying aspects that contribute to suggestibility. It then analyzes the PEACE method of investigative interviewing and points out relevant aspects for reducing the risk of suggestibility and, consequently, false confessions.
Primeras diligencias en la investigación de delitos intracarcelarios en Chile: confusión de roles, prueba ilícita y desprotección a víctimas
Authors: Stippel Jörg , Medina Paula
Published: February 2025

The article analyzes the first investigative steps carried out in cases of crimes committed inside prison facilities in Chile The focus is on the role of the Chilean Prison Service, the Prosecutor's Office and the police. The objective is to evaluate whether these proceedings comply with the role assigned to each institution and respect national and international norms. The hypothesis is that the Chilean prison administration assumes investigative roles that exceed its penitentiary functions. As a result, potentially illicit evidence is generated and the victims of these crimes are left unprotected. The methodology is based on a mixed analysis of 58 crime reports from the prison authorities (2021-2022), covering homicides, injuries, sexual offenses, ill treatment and drug offenses. A quantitative analysis was combined with a qualitative analysis of specific cases. The results highlight that the prison authorities assume key investigative functions, such as guarding the crime scene, interviewing witnesses and suspects, without the authorization of the prosecutor. In addition, prosecutors often issue generic instructions and do not guarantee protection measures for victims. This contradicts national and international standards, affecting the legality and effectiveness of investigations. It is concluded that it is necessary to improve institutional coordination and guarantee the respect for fundamental rights whilst investigating crimes inside prison.
A luta pelas garantias processuais e a mudança de paradigma em matéria de prova: do liberalismo à mass surveillance no processo penal europeu
Authors: Bachmaier Winter Lorena
Published: February 2025

Only with the open source information available of each any person it is possible through the adequate processing to create a detailed profile of practically all aspects of our private life. According to the algorithm used, this can lead to identify an individual as a "person of interest", and this it is only one step away from that same data being used to establish probable cause to open a criminal case, and if the case ends up in a trial, to present such data as evidence. This article discusses how the access to encrypted messaging platforms (as in the Encrochat case) and the massive processing of data through algorithms and artificial intelligence requires to rethink the whole structure of the criminal procedure. It advocates that there is a need to revisit the procedural safeguards developed during the past two centuries to be able to face the risks of the digital era. It concludes that there is a new shift in the gathering of evidence, which calls for strengthening the fair trial rights at the pre-trial stage.
Analysis Change Import Through Shift-Share, Location Quotient and BCG Techniques: Tanjung Priok Port
Authors: Nurmawati Aprilia , Joko Hadi Susilo
Published: February 2025

The purpose of this study is to comprehensively analyze the changes in the competitiveness and specialization of Tanjung Priok Port with a comparison of ports in Indonesia. This study uses shift-share analysis, location quotient, and BCG techniques. The results of the analysis show that the effects of regional shifts negatively impact the mineral, iron, and steel fuel sectors, as well as machinery and electrical equipment, but positively impact other finished textile goods. Tanjung Priok Port has experienced an increase in regional competitiveness and industrial advantages, especially for finished textile goods. By incorporating the location coefficient into the BCG matrix, this study shows that the Port of Tanjung Priok maintains its position in the import of finished textiles, iron and steel, machinery and electrical equipment, and its parts in the Star category. However, mineral fuels have been degraded and remain in the Emerging category.
The world's oldest man-made biological experiment

Biological experiments are often short-lived due to logistical or
resource-related challenges, and short-term observations are
extrapolated to make long-term predictions. However, the effects of
experimental treatments on biological communities and processes take
time to develop. Consequently, the robustness of conclusions drawn from
observations increases with the duration of the experiment. Scattered
throughout central Laos, thousands of large stone jars have been left
behind from ancient burial rituals. The most famous sites in the
Xiengkhouang province are collectively referred to as the Plain of Jars.
These jars form a massive biological experiment: for ~2000
years, rainwater has interacted with geology to create unique yet
replicated aquatic ecosystems influenced by different tree coverage. The
layout of these jars, with clusters of up to several hundred jars
separated by several kilometers, allows for controlled testing of
multiple questions within ecology and evolution. Here, we report for the
first time how these ancient mesocosms can be used to test ecosystem
responses to local abiotic variation and disturbance. We show that tree
cover dominates every jar ecosystem’s state, and that variations in tree
cover density create gradients in oxygen and nutrient concentrations
among jar ecosystems. These findings show that litter contribution to
aquatic ecosystems leads to higher nutrient content and reduces oxygen
concentration, even in systems under different long-term selection in
the oldest man-made ecosystems ever analyzed. This first biological
analysis provides a fundamental understanding of a unique environment
and offers trajectories for future exploration.
Orthodontic forces and moments of three-bracket geometries
Authors: Kei Matthew H. , Schneider Paul M. , Cornelis Marie A. , Cattaneo Paolo M.
Published: February 2025

Objectives

To test the hypothesis of Burstone and Koenig that a three-bracket geometry can be simplified into two adjacent two-bracket geometries, to evaluate the impact of a third bracket on two-bracket geometries, to identify the force systems of 36 three-bracket geometries using archwires of different materials, and to apply these principles to clinical scenarios.

Materials and Methods

A custom-designed orthodontic force jig supported three force transducers fitted with passive self-ligating brackets (Brackets A, B, and C). In Experiment 1, the force system of a three-bracket geometry was compared with two adjacent two-bracket geometries. In Experiment 2, 36 three-bracket geometries were tested when straight wires of varying materials were engaged.

Results

Experiment 1 results showed that the force system of a three-bracket geometry could be simplified into two adjacent two-bracket geometries. Experiment 2 results showed that the impact of the third bracket (Bracket C) affected the force system of the adjacent bracket only (Bracket B), with Bracket C having no statistically significant effect on the force systems at Bracket A. A distinct pattern of forces and moments was found in each of the 36 three-bracket geometries.

Conclusions

In this study, we experimentally validated the hypothesis of Burstone and Koenig, showing that a three-bracket geometry can be simplified into two adjacent two-bracket geometries. The force system of 36 three-bracket geometries was determined, assisting clinicians with better anticipating previously unpredicted and undesirable movements, thereby improving treatment efficiency.
