Authors: Klyuvitkin Alexey , Kravchishina Marina , Starodymova Dina , Bulokhov Anton , Lein Alla
Published: November 2024

Mixing of hydrothermal vent fluids with deep ocean water and near-vent pelagic matter results in particle populations with complex composition consisting of hydrothermally-derived, rock-forming, and biogenic particles. This study is the first investigating of deep sediment trap material collected at the Jan Mayen hydrothermal vent field area at 71° N and 6° W of the southernmost Mohns Ridge in the Norwegian-Greenland Sea. This area is characterized by high magmatic activity, axial volcanic ridges, and mafic-hosted volcanogenic massive sulphide deposits. Data on sinking particle fluxes from two hydrothermal settings, the Troll Wall and Soria Moria vent fields, located about 4 km apart are discussed in the article. In particular, the study emphasise the differences between two hydrothermal settings from each other that demonstrate the geodiversity of hydrothermal processes within the relatively shallow Jan Mayen hydrothermal vent field area affected by the Iceland and Jan Mayen hotspots. The fluxes of sinking hydrothermally derived particles (barite, gypsum, non-crystalline Fe-Si oxyhydroxides, and Fe, Zn, and Cu sulfides) obtained at the Jan Mayen hydrothermal vents made it possible to elucidate the characteristic features of their buoyancy plumes and compare them with similar data reported for other submarine hydrothermal systems. In terms of the composition of the deep-sea hydrothermal particles from buoyant plumes, the studied vent fields are most similar to the Menez Gwen and Lucky Strike vent fields affected by Azores hotspot.

Published: November 2024

This paper reviews recent advances in the synthesis of cobalt-free high-strength tungsten carbide (WC) composites as sustainable alternatives to conventional WC-Co composites. Due to the high cost of cobalt, limited supply and environmental concerns, researchers are exploring nickel, iron, ceramic binders and nanocomposites to obtain similar or superior mechanical properties. Various synthesis methods such as powder metallurgy, encapsulation, 3D printing and spark plasma sintering (SPS) are discussed, with SPS standing out for its effectiveness in densifying and preventing WC grain growth. The results show that cobaltfree composites exhibit high strength, wear and corrosion resistance, and harsh environment stability, making them viable competitors for WC-Co materials. The use of nickel and iron with SPS is shown to enable the development of environmentally friendly, cost-effective materials. It is emphasized that microstructural control and phase management during sintering are critical to improve material properties. The application potential of these composites covers mechanic

Authors: Belotti Angelo , Bisazza Niccolò , Calcari Andrea , Perrone Paolo , Biscarini Andrea
Published: November 2024

This study pioneers a new golf athletic training paradigm that emphasizes the proprioceptive and propulsive function of the feet to enhance swing performance. Twenty-five experienced golf players completed three separate swing sessions: the first before a specific foot proprioceptive intervention (time t0), the second immediately after the intervention (time t1), and the third three minutes after the end of the second session (time t2). During the second and third sessions, participants were instructed to integrate the sequence of foot actions practiced during the proprioceptive intervention into their swing. The club and ball kinematics and the vertical ground reaction exerted by each foot were recorded and compared across sessions. Lead foot pressure increased from t0 to t1 but did not show further increments from t1 to t2. Club speed increased from t0 to t1 and continued to rise, albeit to a lesser extent, from t1 to t2. Ball speed did not change significantly from t0 to t1 but increased from t1 to t2. The benefits of the intervention and the new swing technique progressively propagate with practice from the feet to the club, and finally to the ball. Through the proposed exercises, golfers can progressively develop a refined swing technique that optimizes foot function and enhances swing performance.

Published: November 2024

The rapid advancement of Industry 4.0 and intelligent manufacturing has elevated the demands for fault diagnosis in servo motors. Traditional diagnostic methods, which rely heavily on handcrafted features and expert knowledge, struggle to achieve efficient fault identification in complex industrial environments, particularly when faced with real-time performance and accuracy limitations. This paper proposes a novel fault diagnosis approach integrating Multi-Scale Convolutional Neural Networks (MSCNN), Long Short-Term Memory networks (LSTM), and attention mechanisms to address these challenges. Furthermore, the proposed method is optimized for deployment on resource-constrained edge devices through knowledge distillation and model quantization. This approach significantly reduces the computational complexity of the model while maintaining high diagnostic accuracy, making it well-suited for edge nodes in industrial IoT scenarios. Experimental results demonstrate that the method achieves efficient and accurate servo motor fault diagnosis on edge devices with excellent accuracy and inference speed.

Published: November 2024

Introduction: Knee osteoarthritis (OA) is degenerative chronic disease, characterized by the reduction of articular cartilage with the insurgence of pain and functional limitations. Clinical management includes lifestyle change, analgesic use, intraarticular injections, and, as a last option, surgery. In this setting, intra-articular injections of hyaluronic acid (HA) are a relevant and diffused therapeutic option.
Materials and Methods: In this prospective observational study a cross-linked high molecular weight hyaluronic acid (DIART ONE 90 mg in 3 mL) was administered in single injections to 50 patients aged 18-65 years, with a follow-up at 3, 6, and 12 months. Several scores were evaluated, including the Knee Injury and Osteoarthritis Outcome Score as the primary outcome measure and the Visual Analogue Scale, Time Up and Go Test, Six-Minute Walking Test, General Health Assessment with 36-Item Short Form Health Survey, Zung’s Self-Rating Anxiety Scale, and Zung’s Self-Rating Depression Scale as secondary outcome measures.
Results: We observed a statistically significant improvement in clinical scores at 3 and 6 months, with a reduction of clinical benefit at 12 months. Functional and psychological benefits were significant at 3, 6, and 12 months. No side effects were described except pain associated in the site of injection.
Conclusion: we documented that cross-linked high molecular weight hyaluronic acid (DIART ONE 90 mg in 3 mL) represents an effective option in the management of mild-moderate osteoarthritis.
Thermodynamic Properties of Moisture Sorption and Glass Transition of Coconut (Cocos Nucifera L.) Powder Fortified with Physiologically Active Components
Authors: Lucas Aguirre Juan Carlos , Cortes Rodriguez Misael , Giraldo Giraldo German Antonio
Published: November 2024

The purpose of this work was to determine the thermodynamic properties of coconut powder fortified with physiologically active components, obtained through spray drying (CP+FAC), using the data obtained to construct the sorption isotherms at three temperatures (15, 25, and 35 °C), where the properties calculated were net integral isosteric sorption heat (Qst), differential sorption entropy (ΔS), spreading pressure (Φ), enthalpy (qeq), and entropy (ΔSeq); while determining the glass transition temperature (Tg) and critical storage conditions, like water activity (awc), and moisture content (Xwc) in the CP+FAC. Where Qst increased to a maximum value between the Xw intervals of the monolayer and then diminished with increased moisture content (Xw). The Φ increased with the aw increase and diminished with increased temperature, more notably at 25 and 35 °C. The ΔS diminished with the increase of Xw, which represents an increase in the mobility restriction of the water molecules as the available sites saturate and higher-energy sites are used, which is why water is less available to participate in the deterioration reactions. The qeq diminished with Xw, reaching the maximum value at the lowest Xw, this value is an indication of the greater water-CP+FAC interaction, which means the sorption binding sites are stronger. The ΔSeq went from negative value and increased with the Xw increase, which is associated with greater mobility of the water molecules, favoring the formation of multilayers. The glass transition temperature of the CP+FAC at different aw had an inverse relation, where Tg diminished when increasing aw, going to aw: 0.112: Tg: 69.79 °C at aw values of 0.900: Tg: -39.0 °C, evidencing the plasticizer effect of water, where the Gordon-Taylor model is a reliable predictor of the glass transition temperatures of the CP+FAC. Values of the parameters calculated through non-linear regression were Tgs= 391.67 K and k= 0.753, with R2= 0.977. The critical storage conditions of the CP+FAC, at ambient temperature of 35 °C, were awc of 0.46 and Xwc of 3.8 % (db).

Authors: Song Shixu , Gan Jialing , Long Qiuyue , Gao Zhancheng , Zheng Yali
Published: November 2024

The persistent threat of COVID-19, particularly with the emergence of new variants, underscores the urgency for innovative therapeutic strategies beyond conventional antiviral treatments. Current immunotherapies, including IL-6/IL-6R monoclonal antibodies and JAK inhibitors, exhibit suboptimal efficacy, necessitating alternative approaches. Our review delves into the significance of NAD+ metabolism in COVID-19 pathology, marked by decreased NAD+ levels and upregulated NAD+-consuming enzymes such as CD38 and poly (ADP-ribose) polymerases (PARPs). Recognizing NAD+'s pivotal role in energy metabolism and immune modulation, we propose modulating NAD+ homeostasis could bolster the host's defensive capabilities against the virus. The article reviews the scientific rationale behind targeting NAD+ pathways for therapeutic benefit, utilizing strategies such as NAD+ precursor supplementation and enzyme inhibition to modulate immune function. While preliminary data are encouraging, the challenge lies in optimizing these interventions for clinical use. Future research should aim to unravel the intricate roles of key metabolites and enzymes in NAD+ metabolism and to elucidate their specific mechanisms of action. This will be essential for developing targeted NAD+ therapies, potentially transforming the management of COVID-19 and setting a precedent for addressing other infectious diseases.

Authors: King Stephanie , Jombo Gbanaibolou , Simpson Oluyomi , Duan Wenbo , Bowles Adrian
Published: November 2024

Distributed strain sensing is a powerful tool for in-situ structural health monitoring for a wide range of critical engineering infrastructure. Strain information from a single sensing device can be captured from multiple locations simultaneously, offering a reduction in hardware, wiring, installation costs and signal analysis complexity. Fiber optic distributed strain sensor have been the widely adopted approach in this field, but their use is limited to lower strain applications due to the fragile nature of silica fibre. Coaxial cable sensor offers a robust structure that can be adapted into a distributed strain sensor. They can withstand greater strain events and offer greater resilience in harsh environments. This paper presents the development in methodology for coaxial cable distributed strain sensors. It explores the two main approaches of coaxial cable distributed strain sensing such as time domain reflectometry and frequency domain reflectometry with applications. Furthermore, the paper highlights further areas of research challenges in this field such as: the deconvolution of strain and temperature effects from coaxial cable distributed strain sensor measurements, mitigating the effect of dielectric permittivity on accuracy of strain measurements, addressing manufacturing challenges with the partial reflectors for a robust co-axial cable sensor, and adoption of data-driven analysis techniques for interrogating the interferogram to eliminate concomitant measurement effects with respect to temperature, dielectric permittivity, signal to noise ratio, amongst others.

Published: November 2024

This study uses a novel approach to investigate cognitive dissonance, focusing on the discrepancy between consumer belief and action in response to innovative technological product designs that have emerged in recent years. The study was designed to measure participants’ behavioral plasticity as they were asked to evaluate the degree to which they are comfortable with various AI-based technologies. Participants were presented with paired statements, each reflecting opposing values in relation to different categories of technology, including autonomous vehicles, video game design, smart home technologies, and the use of AI in healthcare. A 'dissonance score' was calculated based on the absolute difference between these paired ratings, providing a quantitative measure of the internal conflict experienced by participants. Findings indicate that adolescents and males are more likely to experience cognitive dissonance, suggesting that these groups make more significant efforts to reconcile their beliefs and practices in the face of conflicting ideas. For adolescents, this may be linked to their thinking patterns as they are still developing, making it harder for them to reconcile new technology with existing standards. These results emphasize the importance of trust and transparency in technology systems. By focusing on making technology feel accessible and ethically based, companies can help reduce the mental health of some users. Furthermore, this study highlights the importance of developing tools that meet the standards of various groups and ensure an inclusive approach to innovation. Further research is needed to understand better how cultural, social, and educational factors influence cognitive dissonance in technology use. By delving deeper into these nuances, future research can help develop solutions that push the boundaries of innovation and make meaningful connections with the people who use them. Ultimately, this research sheds light on how companies can create technologies that feel less intimidating and accessible, thereby providing trust and consistency of action among a wide variety of users.

Published: November 2024

The Internet of Things (IoT) has vast potential to drive connectivity and automation across various sectors, yet energy inefficiency remains a critical barrier to achieving sustainable, high-performing networks. This study aims to identify and address the primary causes of energy wastage in IoT systems, proposing a framework to optimise energy consumption and improve overall system performance. A comprehensive literature review was conducted, focusing on studies from 2010 onwards across major databases, resulting in the identification of eleven key factors driving energy inefficiency: offloading, scheduling, latency, changing topology, load balancing, node deployment, resource management, congestion, clustering, routing, and limited bandwidth. The impact of each factor on energy usage is analysed, leading to a proposed framework that incorporates optimised communication protocols (such as CoAP and MQTT), adaptive fuzzy logic systems, and bio-inspired algorithms to streamline resource management and enhance network stability. This framework presents actionable strategies to improve IoT energy efficiency, extend device lifespan, and reduce operational costs. By addressing these energy inefficiency challenges, the study provides a path forward for more sustainable IoT systems, emphasising the need for continued research into experimental validations, context-aware solutions, and AI-driven energy management to ensure scalable and resilient IoT deployment.

Self-disclosure is considered highly important for prospective counselor students. When facing clients, conscientious openness within certain boundaries aids in enhancing counseling effectiveness. The counselor's openness during counseling sessions can encourage clients to open up themselves. Hence, this research aims to develop self-disclosure among students of the Islamic Guidance and Counseling Program through journaling techniques. The methodology employed is quantitative experimentation using a pre-experimental design known as the one-group pretest-posttest design. The research sample consists of 35 individuals randomly selected from a total population of 155 students of the Islamic Guidance and Counseling Program, Class of 2022. Data collection involved the use of a self-disclosure questionnaire, which was subsequently analyzed using the Wilcoxon test. From the Wilcoxon test results, a significance value of 0.000 was obtained, indicating 0.000 < 0.05. Therefore, based on the decision-making foundation in the Wilcoxon signed-ranks test, it can be concluded that the null hypothesis (Ho) is rejected, and the alternative hypothesis (Hα) is accepted. Consequently, it is inferred that there is a difference in the level of self-disclosure among students of the Islamic Guidance and Counseling Program before and after being provided with journaling techniques.
Vergüenza y autoalienación: Una perspectiva psicoanalítica basada en el trauma
Authors:   IARPP, Shaw Daniel
Published: November 2024

Self-alienation is an expression of deeply internalized shame. The self-alienated individual feels
trapped, imprisoned by shame. Psychotherapy patients with significant relational trauma typically
reveal a persistent internal battle against self-doubt, self-condemnation, and often self-loathing.
They are referencing shameful fears and beliefs about themselves that are born from problematic
attachment and developmental experiences. The author provides illustrations of work with selfalienated individuals integrating psychoanalytic principles with concepts from contemporary
traumatology, with a focus on helping patients develop self-compassion as the chief agent of
therapeutic healing and growth.

Fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith), a threat to maize production systems, is a highly polyphagous pest of global significance. As per the National robotics policy for application of drones in agriculture in India, a comparative study of residue dynamics between drone and conventional application of the prepared premix [Chlorantraniliprole (Chl) and Emamectin benzoate (EB)] liquid formulation (CEOD), at 70 g (T1) and 140 g (T2) /ha at two stages of rabi maize plant was carried out. QuEChERS clean-up technique coupled with LC-MS/MS (liquid chromatography-tandem mass spectroscopy) analysis was used for simultaneous estimation of Chl and EB in maize leaves, grains, cob and soil. The method was validated in terms of accuracy, precision, sensitivity and linearity. The terminal residues of both the pesticides in grain were below the quantification limit (For Chl-0.0001 to 0.0002 mg kg-1 and for EB-0.0003 to 0.0004 mg kg-1) in case of drone application. Pre-Harvest interval of both the compounds was shorter in case of drone spray (13.93 -16.19 days for Chl and 29.76-32.18 days for EB) as compared to conventional application (23.19- 32.58 days for Chl and 68.35-73.25 days for EB). Hence, the safe waiting period for harvest will be much lower in case of drone spray. Safety assessment studies revealed that there is no consumer risks for drone applied formulation at recommended dose on maize crop in Indian scenario.

Background:
Primary small vessel CNS vasculitis (sv-cPACNS) is a challenging inflammatory brain disease in children. Brain biopsy is mandatory to confirm the diagnosis. This study aims to develop and validate a histological scoring tool for diagnosing small vessel CNS vasculitis.
Methods:
A standardized brain biopsy scoring instrument was developed and applied to consecutive full-thickness brain biopsies of pediatric cases and controls at a single center. Stains included immunohistochemistry and Hematoxylin & Eosin. Nine North American neuropathologists, blinded to patients’ presentation, diagnosis, and therapy, scored de-identified biopsies independently.
Results:
A total of 31 brain biopsy specimens from children with sv-cPACNS, 11 with epilepsy, and 11 with non-vasculitic inflammatory brain disease controls were included. Angiocentric inflammation in the cortex or white matter increases the likelihood of sv-cPACNS, with odds ratios (ORs) of 3.231 (95CI: 0.914-11.420, p = 0.067) and 3.923 (95CI: 1.13-13.6, p = 0.031). Moderate to severe inflammation in these regions is associated with a higher probability of sv-cPACNS, with ORs of 5.56 (95CI: 1.02-29.47, p = 0.046) in the cortex and 6.76 (95CI: 1.26-36.11, p = 0.025) in white matter. CD3, CD4, CD8, and CD20 cells predominated the inflammatory infiltrate. Reactive endothelium was strongly associated with sv-cPACNS, with an OR of 8.93 (p = 0.001). Features reported in adult sv-PACNS, including granulomas, necrosis, or fibrin deposits, were absent in all biopsies. The presence of leptomeningeal inflammation in isolation was non-diagnostic.
Conclusion:
Distinct histological features were identified in sv-cPACNS biopsies, including moderate to severe angiocentric inflammatory infiltrates in the cortex or white matter, consisting of CD3, CD4, CD8, and CD20 cells, alongside reactive endothelium with specificity of 95%. In the first study of its kind proposing histological criteria for evaluating brain biopsies, we aim to precisely characterize the type and severity of the inflammatory response in patients with sv-cPACNS; this can enable consolidation of this population to assess outcomes and treatment methodologies comprehensively.
Comparison of bioabsorbable screw versus metallic screw fixation for tibial tubercle fractures in adolescents: A retrospective cohort study

Background: Displaced tibial tubercle (TT) fractures in adolescents are typically treated with open reduction and internal fixation. While metallic screw (MS) fixation provides strong stability, it often results in a high incidence of postoperative screw head protrusion or irritation, leading to additional removal surgery. Bioabsorbable screw (BS) fixation presents an alternative that may avoid these issues, though its stability has not yet been extensively documented in the literature. This study aims to compare the efficacy of BS versus MS in the fixation of TT fractures.
Methods: A retrospective analysis was conducted on adolescent patients with TT fractures who underwent surgical treatment from September 2015 to September 2023. Patients were divided into two groups based on the fixation method: The BS group and the MS group. Data collected included patient demographics, fracture details, treatment strategies, radiological and clinical rehabilitation outcomes, and postoperative complications. Knee joint function was evaluated using the Lysholm and Tegner scores. Statistical analysis was performed to identify differences between the variables of the two groups.
Results: A total of 30 patients with 32 fractures were included, with 15 fractures in the BS group and 17 in the MS group. The average follow-up period was 42.1 (range: 12.0-109.5) months. The demographic characteristics, fracture details, and treatment strategies were comparable between the two groups. No significant differences were observed between the groups in fracture healing time, time to return to pre-injury activities, or knee joint function as assessed by the Lysholm and Tegner scores at the final follow-up. However, compared with the MS group, the BS group showed a shorter time to regain full range of motion (ROM) in the knee joint and experienced lower rates of postoperative hardware irritation and joint stiffness.
Conclusions: Both BS and MS fixations are safe and effective for treating adolescent TT fractures. BS fixation has the advantages of avoiding hardware irritation, facilitating earlier recovery of knee joint ROM, reducing the incidence of joint stiffness, and eliminating the need for additional removal surgery.

Published: November 2024

Background:
The anti-melanoma differentiation-associated gene 5 (anti-MDA5) antibody dermatomyositis is known for its association with rapidly progressive interstitial lung disease (RP-ILD) and ulcerative skin lesions, often presenting with or without muscle involvement. The aim of this study was to identify distinct clinical and laboratory features that could be used to evaluate disease progression in an ethnically diverse cohort of anti-MDA5 dermatomyositis patients at a U.S. academic center.
Methods:
A retrospective chart review was conducted on dermatomyositis patients hospitalized at our institution between January 2014 and June 2023. The data were analyzed via Fischer’s exact test and a t test.
Results
Among the 195 dermatomyositis patients reviewed, 22 tested positive for the MDA5 antibody, comprising thirteen adults and nine pediatric patients. Among these individuals, ten adults exhibited ILD, three of whom were classified as having RP-ILD. Notably, all pediatric patients displayed some level of muscle weakness. The five pediatric patients diagnosed with ILD had a higher prevalence of myositis. The incidence of ILD was significantly greater in the adult Black Hispanic and African American populations (10/15 cases, p = 0.035) than in the other ethnicities, with three cases resulting in fatal RP-ILD. The overall mortality rate of 13.6% was more favorable than the previously reported 40–60% rates.
Conclusion:
In conclusion, while the general disease characteristics were similar between adult and pediatric patients, myositis was more prevalent in the pediatric population. Adults, particularly those from Black and African American backgrounds, experienced a greater incidence of ILD, leading to poorer outcomes.

Background
Cognitive impairments are common in neuropsychiatric disorders like Attention Deficit Hyperactivity Disorder (ADHD), bipolar disorder (BD), and schizophrenia (SZ). While previous research has focused on specific brain regions, the role of the procedural memory as a type of long-term memory to cognitive function in these disorders remains unclear. This study investigates the association between cognitive impairments and alterations in resting-state functional connectivity (rs-FC) within procedural memory network in patients with these disorders.
Methods
This study analyzed resting-state functional magnetic resonance imaging (rs-fMRI) data from 40 individuals with ADHD, 49 with BD, 50 with SZ, and 50 healthy controls (HCs). A procedural memory network was defined based on the selection of 34 regions of interest (ROIs) associated with the network in the Harvard-Oxford Cortical Structural Atlas (default atlas). Multivariate ROI-to-ROI connectivity (mRRC) was used to analyze the rs-FC between the defined network regions. Significant differences in rs-FC between patients and HCs were identified (P < 0.001).
Results
ADHD patients showed increased Cereb45 l - Cereb3 r rs-FC (p = 0.000067) and decreased Cereb1 l - Cereb6 l rs-FC (p = 0.00092). BD patients exhibited increased rs-FC between multiple regions, including Claustrum r - Caudate r (p = 0.00058), subthalamic nucleus r - Pallidum l (p = 0.00060), substantia nigra l - Cereb2 l (p = 0.00082), Cereb10 r - SMA r (p = 0.00086), and Cereb9 r - SMA l (p = 0.00093) as well as decreased rs-FC in subthalamic nucleus r - Cereb6 l (p = 0.00013) and Cereb9 r - Cereb9 l (p = 0.00033). SZ patients indicated increased Caudate r– putamen l rs-FC (p = 0.00057) and decreased rs-FC in subthalamic nucleus r – Cereb6 l (p = 0.000063), and Cereb1 r – subthalamic nucleus r (p = 0.00063).
Conclusions
This study found significant alterations in rs-FC within the procedural memory network in patients with ADHD, BD, and SZ compared to HCs. These findings suggest that disrupted rs-FC within this network may contribute to cognitive impairments observed in these disorders.
