Modern optimization algorithms face critical challenges in high-dimensional non-convex landscapes, including local minima entrapment and noise sensitivity. This work introduces a quantum-classical hybrid framework synergizing counterpoint-inspired harmonic coordination with variational quantum optimization. The key innovation lies in a dynamically adaptive harmony matrix Hij that orchestrates exploration-exploitation tradeoffs through musical tension-resolution principles. Implemented on a quantum annealer with 1000+ qubits, the algorithm achieves 99.96% accuracy on Rastrigin functions (d=10^6) under 18dB noise, despite a 27.8% energy overhead from quantum error correction. Comparative analysis against QAOA and classical benchmarks demonstrates 2.1x speedup and 94.7% lower divergence rates. These advancements establish a new paradigm for optimization in noisy, high-dimensional environments.

AbstractSaint Martin’s Island, situated in the Bay of Bengal has important geopolitical and maritime security value to Bangladesh, particularly in the post-Hasina period. The island has an important place in the nation's territorial sovereignty and economic potential, such as through tourism and marine production. However, in the recent changing political scenario and changing regional situation, Saint Martin's Island is confronted by a number of maritime security issues. These are, for example, unresolved territorial disputes with Myanmar, environmental degradation, piracy and consequences of climate change. This paper explores the strategic vulnerabilities of the island, analyzing its geopolitical significance and the security challenges it faces in a changing political environment. It also points out the importance of enhanced maritime security, regional coordination, and green development policies in order to secure the island's future. The findings suggest that a balanced approach involving national security strategies, international collaboration, and sustainable environmental management is essential for protecting the island's long-term security and prosperity.

AbstractThis paper discusses the strategic rapprochement between Russia and North Korea with a specific focus on its negative influence on regional security and world peace. It details how these two countries benefit from the partnership: Russia receives political and strategic assistance while North Korea obtains economic, technology, and military assistance. Employing qualitative research methodology and using various historical and political texts, this work outlines some of the negative impacts of this alliance which include the most restrained form of international relations that is the possibility of resorting to the use of force, and more particularly, the use of such international force in Northeast Asia, which could cause regional instability. The work also maps out worldwide reactions such as sanctions and the use of force and suggests appropriate policy options such as diplomatic actions in the international community, external aid, and the development of a better security system to counter such threats. This research emphasizes the importance of international collaboration to deal with the risks brought about by this alliance and enable stability in the international landscape.

headspace is Australia's National Youth Mental Health Foundation. There are over 165 youth-friendly multidisciplinary services located in every state and territory across Australia. Considerable Government funds are allocated to headspace centres with the aim of targeting mild-to-moderate mental health disorders for young people aged 12 to 25 years. Young people present for help for a wide range of concerns including mood disorders, anxiety disorders, peer difficulties, and substance use issues. Recent research has demonstrated that a high percentage of young people accessing care at headspace centres are experiencing significant body image concerns and are engaging in disordered eating behaviours. These include dietary restriction, binge eating and purging behaviours such as self-induced vomiting. The headspace centre model includes both general practitioners and mental health clinicians as part of the clinical team. This multi-disciplinary model enables centres the basic staffing needed to provide effective interventions for mild-to-moderate eating disorder presentations. While offering early intervention for eating disorders is within the scope of headspace centres, full integration of eating disorders care into the core business of headspace centres is still ongoing. Many headspace clinicians are not confident in assessing for or treating eating disorders leading to non-specific treatments for eating behaviours that are not evidence based or referrals to external specialized services which are associated with high costs and long waiting times, preventing access to timely and affordable early intervention. headspace centres are well placed with existing resources to provide effective and accessible early intervention for eating disorders to young Australians at risk.

TITLE OF CASE A successful termination of bidirectional ventricular tachycardia followed by intravenous lidocaine. KEY CLINICAL MESSAGE Bidirectional ventricular tachycardia, once a hallmark of severe digitalis toxicity, can also result from causes like catecholaminergic polymorphic VT, aconite poisoning, genetic channelopathies, myocarditis, and myocardial infarction. While electrical cardioversion is recommended for unstable VT, tailored treatments, including intravenous lidocaine, may be effective for BVT-associated myocardial infarction. INTRODUCTION Bidirectional ventricular tachycardia (BVT) is a rare and life-threatening arrhythmia with a limited differential diagnosis, including digitalis toxicity, catecholaminergic ventricular tachycardia, aconite poisoning, hereditary channelopathy syndromes, myocarditis and myocardial infarction[1 2]. The precise cause of BVT remains poorly understood. Current guidelines for ventricular tachycardia management typically recommend beta-blockers, propafenone, or flecainide[3]. However, intravenous lidocaine has not been previously recognized as a treatment for BVT. We report a case of a patient presenting to the emergency department with chest pain and hypotension, diagnosed with unstable BVT, which was successfully treated with intravenous lidocaine, restoring normal sinus rhythm. The patient was stabilized, transferred to the cardiac care unit, and later diagnosed with myocardial infarction after cardiac catheterization. The pathophysiology of BDVT is similar to other forms of ventricular tachycardia, involving delayed afterdepolarization, reentry, and automaticity. Given that lidocaine is effective for ventricular tachycardia associated with MI, it may also be beneficial in BVT cases associated with myocardial infarction. KEYWORDS Ventricular, Tachycardia, Myocardial Infarction, Lidocaine, Acute Coronary Syndrome. CASE HISTORY/EXAMINATION An Asian male who was in his 40s with a significant medical history of morbid obesity (BMI of 31), ischemic cardiomyopathy, and a decreased left ventricular ejection fraction (19%) without a prior history of cardiac arrhythmias visited the ED with 30 minutes of central chest discomfort radiating to the left arm. The patient was alert with a blood pressure of 90/69 mmHg, a heart rate of 167 beats per minute, a respiratory rate of 22 breaths per minute, and a capillary refill time of less than 2 seconds. No signs of heart failure were observed. A 12-lead electrocardiogram (ECG) showed significant tachycardia with a rate of 164 beats per minute and bidirectional QRS morphology strongly suggestive of BVT as shown in Figure 1. Following the initial evaluation, the patient remained hypotensive, requiring continuous cardiac monitoring and immediate cardiology consultation with the differential diagnosis of ischemic cardiomyopathy-related VT, acute myocardial infarction, and toxin-related BVT. The patient was subsequently treated with 100 mg of intravenous lidocaine over three minutes instead of synchronized electrical cardioversion since it could worsen his ventricular ejection fraction. Five minutes after lidocaine had been administered, the ECG returned to sinus rhythm as shown in Figure 2 with a blood pressure of 120/58 mmHg. Laboratory studies revealed a troponin-T level of 520 ng/L, while the test results were unremarkable. Digoxin level was not determined due to the absence of a history of drugs or toxin-related ingestion. INVESTIGATIONS Laboratory studies revealed a troponin-T level of 520 ng/L, while the test results were unremarkable. Digoxin level was not determined due to the absence of a history of drugs or toxin-related ingestion. DIFFERENTIAL DIAGNOSIS

This study investigates aging heterogeneity in diabetes-related tissues using the p21-3MR mouse model, focusing on p16 and p21 as markers of senescence. Type 2 diabetes, a common age-related disease, impacts multiple organs, and the study examines aging patterns in tissues such as the pancreas, kidney, heart, adipose tissue, femur, spleen, thymus, liver, and lungs. The results reveal significant aging heterogeneity and asynchrony across different organs during diabetes progression, with varying responses to anti-aging treatments. Specifically, the combination of dasatinib and quercetin demonstrated superior anti-aging effects in several tissues compared to p21 intervention alone, while p21 intervention showed distinct responses in adipose tissue and bone marrow. Immune organs displayed immunosenescence heterogeneity, and the liver and lungs showed greater sensitivity to vascular aging. This is the first study to use the p21-3MR model to explore aging heterogeneity and the differential effects of anti-aging treatments in diabetic tissues. The findings highlight the need for personalized anti-aging strategies, particularly in adipocytes and metabolic disorders. Future research should focus on understanding the mechanisms of p21 high cells in aging-related diseases, offering insights for more effective treatments.

This paper presents a predictive model reference adaptive system (MRAS) speed estimator for Permanent Magnet Synchronous Machines. The speed estimator is based on the finite control set model predictive control (FCS-MPC) principle. A search method is utilized to find the best estimated speed at each sampling interval that produces the smallest speed estimation error signal. This method replaces the PI controller which is typically employed by MRAS estimators. The speed estimator has been experimentally tested using a 2.1kW PMSM. Results show improved performance, especially during fast load transients for the novel method compared to the PI-based MRAS method.

Root exudates play a pivotal role in regulating rhizosphere microbial communities; however, the effects of different types of salt stress on rhizosphere rare bacteria via root exudates remain unclear. This study employed targeted metabolomics and high-throughput sequencing to investigate the impacts of three types of salt stress-alkaline, neutral and mixed-on the root exudates and rhizosphere rare bacteria of Leymus chinensis in a pot experiment. Alkaline and mixed salt stress significantly increased the carbon content and C:N ratio of root exudates, while all types of salt stress enhanced the exudate secretion rate. The composition of root exudates significantly influenced the composition of rare bacterial communities in the rhizosphere; however, their quantitative impact was smaller than that of soil pH. L. chinensis mitigated the effects of alkaline and mixed salt stress on the diversity and evenness of rare microbial communities by increasing the C:N ratio of root exudates, though this adjustment may also inhibit the stability of rare microbial networks. Salt stress-induced changes in electrical conductivity altered the differential secretion of root exudates, promoting the diversity and evenness of microbial communities. These findings advance our understanding of how plant root exudates and rhizosphere rare bacteria respond to different types of salt stress, emphasizing the crucial role of plants in modulating rhizosphere rare microbial communities through exudate secretion.

IntroductionRestoring missing incisor presents a complex challenge, requiring a careful balance between aesthetics and functionality, several therapeutic options can be considered, including conventional approaches such as a three-unit fixed partial denture (FPD), a single-tooth implant restoration which may be limited due to medical, anatomical or financial constraints. A resin-bonded fixed partial denture (RBFDP) offers a more conservative alternative, as it requires minimal to no tooth preparation compared to conventional (FPD). Thus, the general selection criteria include the patient’s age and overall health, while the local criteria focus on the condition of the adjacent teeth and the occlusal scheme. All-ceramic bridges can be made using various types of ceramic materials, each one presents advantages and inconveniences. Tetragonal zirconia polycrystal stabilized with 3 mol% yttria (3Y-TZP) has been among the most used dental ceramic materials in recent years, it is a reliable restorative material for making fixed dental prostheses (FDPs) with higher strength and toughness properties compared to other dental ceramic materials. However, due to its high opacity, early-generation zirconia material was specifically used as a framework for FDPs and veneered with aesthetical materials. Recently, new zirconia materials have been developed with enhanced translucent properties, allowing full-contour (monolithic) FDPs to overcome the clinical issues of veneer chipping and fracture, Translucent multi-layered zirconia products differ from one another, even when some share the same chemical composition across layers, due to the use of gradient shade technology.This manuscript outlines a case report about the replacement of mandibular incisor by monolithic high resistance multi-layered zirconia 3% mol yttrium content produced with grade shade technology resin-bonded fixed partial denture (RBFPD), fabricated using CAD-CAM technology 1 2 34 5 6

For decades, precipitation passive collectors for water stable isotopes (δ 2H, δ 18O, and d-excess) analysis have been debated regarding secondary fractionation, sample integrity over time, and sampling costs. This study compares the performance of precipitation (N=36) passive collectors for water isotope analysis in the Dallas-Fort Worth Metroplex (north-central Texas, USA). Two systems were compared: (1) the low-cost OPEnS collector (version 3.0) and (2) the Palmex RS1 collector combined with a portable autosampler for sub-daily sampling. Our results showed no significant variation in the annual arithmetic mean ( p=0.110 for δ 18O, p=0.477 for δ 2H, and p=0.054 for d-excess) between the OPEnS collector and the Palmex-autosampler setup. The annual precipitation weighted means in δ 18O, δ 2H, and d-excess were -4.25±1.94‰, -21.2±15.1‰ and 12.8±7.1‰ for the OPEnS and -4.05±2.2‰, -20.6±15.3‰ and 11.9±6.7‰ for the Palmex-autosampler setup. Strong linear correlations in δ 2H ( r2=0.96), δ 18O ( r2=0.91), and d-excess ( r2=0.83) were found between the OPEnS and Palmex-autosampler setup. However, the best agreement in precipitation amounts was found between the OPEnS and Palmex RS1 (alone) ( r2=0.91). Combining the Palmex with an autosampler resulted in a lower precipitation amount performance ( r2=0.59). Precipitation amount discrepancies may occur because of i) the vertical instability in the OPEnS collector during windy and heavy rainfall conditions and ii) the Palmex-autosampler mechanical challenges related to ponding or residual water in the connecting vinyl tubing and distributor’s arm movement across the 24 bottles carousel. Meteoric water lines suggest a larger influence of secondary evaporation when using the Palmex-autosampler setup (δ 2H=7.00×δ 18O+6.72; r2=0.84) than the OPEnS collector (δ 2H=7.33×δ 18O+8.87; r2=0.84). The OPEnS collector is a consistent, cost-effective, and reliable alternative for precipitation sampling similar to the Palmex RS1 collector (alone). Autosampler assemblages to Palmex RS1 or other in-house collectors should be carefully tested and revised regarding precipitation amount and post-sampling evaporation.

Introduction QRS transition during the threshold test is the gold standard for confirming direct capture of the Conduction System in patients with Left Bundle Branch Pacing (LBBP). Still, we have limited data on the kinetics of QRS transition over time. Microdislodgement is a known complication of LBBAP; however, its true incidence depends on the thoroughness of follow-up. We aimed to evaluate the kinetics and disappearance of QRS transition in patients undergoing Left Bundle Branch Pacing (LBBP), assess the diagnostic yield of QRS transition at various time points, and characterize microdislodgement. Methods This prospective study included patients who underwent successful LBBP procedures at a tertiary center between January 2022 and February 2024. Based on the kinetics of QRS transition during intraoperative, postoperative, and follow-up threshold tests, microdislodgement was assessed. Results LBB capture was confirmed in 118 of 155 Left Bundle Branch Area Pacing (LBBAP) patients (76.1%), which defined our LBBP population. Intraoperative QRS transition was observed in 86.4%, which decreased significantly postoperatively (47.0%) and at follow-up (33.0%)—in 92.0% of LBBP patients’ capture of LBB remained, while microdislodgement occurred only in 5.0% of LBBP cases. Conclusion This study evaluates QRS transition kinetics in LBBAP patients, showing significant intraoperative detectability in patients with direct capture of LBB that decreases postoperatively and at first follow-up. Our classification of microdislodgement aids in understanding its impact on pacing outcomes.

Background: Williams syndrome (WS) is a rare genetic condition frequently associated with cardiovascular anomalies, particularly supravalvular aortic stenosis (SVAS). The coexistence of SVAS, aneurysmal dilation, and infective endocarditis (IE) with vegetations in the aortic arch is exceedingly rare.Case presentation: We describe an an 8-year-old Arab boy from Syria with WS who presented with fatigue, tachycardia, dyspnea, fever, chills, and night sweats. Transthoracic echocardiography revealed a dilated aortic arch with large vegetation at the origin of the brachiocephalic trunk and SVAS. Despite 10 days of intravenous antibiotic therapy, vegetations persisted, necessitating urgent surgery. The ascending aorta was replaced using the McGoon technique with complete excision of infected tissue. Postoperative recovery was uneventful, and follow-up imaging showed good left ventricular function without aortic gradient.Conclusion: This case underscores the importance of early recognition and timely surgical intervention in preventing catastrophic outcomes in patients with WS and complex cardiovascular involvement.Keywords: Williams syndrome, supravalvular aortic stenosis, aneurysm, vegetations, endocarditis, case report.

Tau oligomers are recognized for their critical role in causing neuronal toxicity and synaptic dysfunction in a diverse array of neurodegenerative diseases collectively referred to as tauopathies. However, the discovery of drugs that specifically target tau oligomers has been impeded by the absence of appropriate screening methods. Here, we suggest a drug screening platform based on tau amyloid corona-shelled nanoparticles (TACONs) to assess the efficacy of tau oligomer-degrading compounds through aggregation-induced colorimetric responses of TACONs. TACONs were engineered via the encapsulation of gold nanoparticles (AuNPs) with homogeneous tau oligomers by leveraging heparin as a co-factor. Our TACON-based strategy harnesses two primary functions of AuNPs: (i) catalytic activators for the selective isolation of tau oligomers and (ii) optical reporters for quantifying colorimetric responses induced by tau oligomer-degrading agents. To validate this approach, we employed proteases that can degrade tau oligomers (protease XIV and plasmin) along with various small molecules known to aid in the treatment of tauopathies. Furthermore, we significantly enhanced screening efficiency by integrating a time-series deep learning architecture, enabling rapid identification of effective compounds within one hour. These results highlight the great potential of deep learning-assisted TACON-based drug screening platform as a powerful strategy for streamlining drug discovery in tauopathies.

Luteinizing hormone (LH) and follicle-stimulating hormone (FSH) are essential for reproductive health. Patients with severe LH and FSH deficiencies require exogenous hormone therapy to restore fertility. The combination of recombinant FSH (follitropin alfa, r-hFSH) and recombinant LH (lutropin alfa, r-hLH) in a 2:1 IU ratio addresses these deficiencies and stimulates follicular development in women undergoing assisted reproductive technologies. This prospective, observational, real-world post-marketing surveillance study was conducted from August 2011 to May 2018 at 24 sites in Korea to evaluate the safety and effectiveness of r-hFSH/r-hLH in patients with severe LH and FSH deficiencies. Safety was assessed by the incidence of adverse events (AEs) and adverse drug reactions (ADRs), while effectiveness was evaluated based on follicular growth and pregnancy rates. A total of 600 patients were included in the safety analysis, with 532 in the effectiveness evaluation. The mean age was 34.58 years, and the mean LH and FSH levels were 0.70 IU/L and 3.25 IU/L, respectively. The overall incidence of AEs was 2.7%, with ADRs reported in 2.2%. Ovarian hyperstimulation syndrome (OHSS) occurred in 1.3% of patients. Notably, 99.25% of patients achieved mature follicular growth, and the pregnancy rate was 42.67%. This study identified no new safety concerns, demonstrating the effectiveness of r-hFSH/r-hLH in treating severe LH and FSH deficiencies in Korean women. These findings highlight the value of r-hFSH/r-hLH in personalized fertility treatments. Clinical Trial Number NCT01416987 (Registration Date: July 1, 2014)

Psychostimulants are used to enhance cognitive functions such as attention and alertness, particularly in contexts of high academic demand. This study aims to assess the prevalence of psychostimulant use among medical students and residents in Chile, identifying associated factors such as academic stress, level of training, and contextual elements. A cross-sectional study was conducted through a survey administered to 314 participants, the majority of whom were female (72.3%), with 38.2% being 6th-7th year students and residents. The results revealed that among responders 17.8% reported using methylphenidate (MPH), 13% lisdexamfetamine (LDX/AMPH), and 11.4% modafinil, with a low proportion consuming them under medical prescription. A significant association was found between high levels of academic stress and the use of MPH (p=0.0497) and modafinil (p=0.0194). Additionally, students in clinical stages reported higher consumption of MPH (p=0.0004) and LDX/AMPH (p=0.038). The use of psychostimulants among medical students raises ethical and public health concerns, considering the risks of dependency, adverse effects, and academic inequalities. The consumption of psychostimulants is high among medical students and residents in Chile, particularly in advanced stages of training. It highlights the need for ethical and educational interventions in the academic environment.

With increasing numbers of older adults worldwide, multimorbidity and polypharmacy are on the rise, highlighting the risks of potential drug-drug interactions (pDDIs). As cardiovascular agents are among the most prescribed medications, we performed an observational cross-sectional study to determine the prevalence of pDDIs in a cardiology department of a secondary hospital. Patient data was obtained from medical records and screened for pDDIs using the Micromedex drug interaction software. Descriptive statistics, Chi-square (χ2) test, Student’s t test and Pearson’s correlation test were used to analyse the results. Out of 50 participants, 45 (90%) had at least one pDDI. A total of 266 pDDIs were identified, with more than half classified as major. At least one major pDDI was found in 78% of patients. 42% of patients were at an increased risk of bleeding due to pDDIs. A statistically significant relationship was found between the detection of pDDIs and both patient age (p = 0.005) and the number of drugs used (p < 0.001). Our findings pose questions about the wider prevalence and risks of pDDIs among patients with cardiovascular disease.

Cells rely on precise spatiotemporal control of signalling pathways to ensure functional specificity. The compartmentalisation of cyclic AMP (cAMP) and protein kinase A (PKA) signalling enables distinct cellular responses within a crowded cytoplasmic space. Traditionally, compartmentalisation has been attributed to PKA anchoring, phosphodiesterase-mediated cAMP degradation, and restricted cAMP diffusion. Emerging evidence suggests that liquid-liquid phase separation (LLPS) might play a significant role in organising cAMP signalling. LLPS has been implicated in receptor clustering, cyclic nucleotide synthesis, effector activation, and signal termination, offering a dynamic mechanism for spatially restricting cAMP activity. Notably, PKA RIα condensates appear to act as cAMP reservoirs, modulating local cAMP availability and phosphodiesterase-mediated degradation. Disrupting LLPS-mediated condensation of cAMP/PKA pathway components has been linked to cancer and neurodegeneration, pointing to physiological relevance. This review explores current evidence on LLPS in cAMP signalling, highlighting the implications for signal compartmentalisation and functional specificity.

This work presents a new approach to designing high-performance and efficient pumps based on dielectric elastomer actuators. By considering the entire system including load from the beginning of the design process, the advantages of dielectric elastomers are specifically utilized to minimize the required space while optimizing performance within that compact volume. The process is model-based, ensuring that every aspect, from individual components to the complete system, is carefully optimized for efficiency and power. This approach represents an important step in the use of dielectric elastomer actuators for real-world applications, as the pump is more powerful over a wide working range compared to the state of the art and can therefore be used in applications where conventional pumps are still commonly employed.

Psychological diagnoses serve as the foundation for treatment and interventions, playing a critical role in improving individuals’ quality of life. However, when initial information is distorted, family environments are toxic, and systemic negligence is prevalent, the likelihood of misdiagnosis increases significantly. This article explores the consequences of misdiagnoses and contributing factors, offering strategies to improve diagnostic systems. Findings indicate that misdiagnoses can lead to vicious cycles, driving individuals toward psychological, social, and medical crises. However, the use of multi-axial diagnostic tools, increased awareness among professionals, and active participation of individuals can help reduce diagnostic errors.

The Cherruault decomposition method is proposed as a means to introduce modifications to Newton’s iterative scheme, aiming to enhance efficiency and improve convergence order. Regarded as superior, this technique boasts applicability across a variety of numerical problems. It is noteworthy to mention that algorithms due to Weerakoon and Fernando [13] and Homeier [7] are actually attributed to Traub [12].

Amyloid beta plaques and tau tangles are the primary hallmarks of Alzheimer’s disease (AD). Recently, marked advances have been made in terms of passive anti-Aβ immunotherapy for AD, which have been supported by evidence from AD animal models and clinical trials. While innate immunity significantly contributes to the pathology of AD, it does not fully clarify the immune mechanisms linked to its pathogenesis. Consequently, focus should be directed toward adaptive immunity, encompassing both humoral immunity, primarily governed by B cells, and cellular immunity, predominantly influenced by T cells. T cells, in particular, may also be important in AD pathogenesis, as indicated by many lines of evidence from clinical and animal studies. Furthermore, T cells that infiltrate the central nervous system (CNS) have demonstrated both protective and detrimental effects on neural tissue in AD. Because autoreactive CD8+ T cells were expected to be cytotoxic to CNS cells, they have received less attention. Nevertheless, a significant amount of evidence now suggests that CD8+ Treg cells play a role in multiple diseases. However, the function of anti-Aβ-specific CD8+ T cells in AD has remained ambiguous. Many subsets of CD8+ T cells exist, which have been well-studied in terms of autoimmunity. We suggest that these CD8+ T cell subsets identified in AD studies could constitute a promising area for future AD research.
