Residual Deep Learning for Realized Volatility Using a Hybrid HAR-LSTM Model with ARIMA Features and SHAP Interpretability

Classical linear models such as the Heterogeneous Autoregressive Realized Volatility (HAR-RV) model are difficult to beat at short horizons, yet cannot capture nonlinear, regime-dependent dynamics, while pure deep learning approaches typically overfit. This paper proposes a resid...

Adjunctive Low-Level Laser Therapy and Deep Oscillation in Pulmonary Rehabilitation for Post-Tuberculosis Lung Disease

Background: Post-tuberculosis lung disease (PTLD) is associated with persistent functional impairment and reduced quality of life. This study evaluated the association between the addition of low-level laser therapy (LLLT) and deep oscillation (DO) to structured pulmonary rehabil...

Traumatic Intracranial Vascular Lesions in Adults Undergoing Vascular Imaging After Traumatic Brain Injury: A Systematic Review and Meta-Analysis

Background and Objectives: Traumatic intracranial vascular lesions are rare but severe complications of traumatic brain injury (TBI) and include arterial and venous injuries such as arterial dissections, pseudoaneurysms, arterial occlusions, venous sinus thrombosis, arteriovenous...

From Data to Decision: Interpretable and Reliable Heart Disease Risk Prediction.

BACKGROUND: Heart disease is the leading cause of morbidity and mortality worldwide, highlighting the need for accurate and clinically meaningful risk prediction tool. METHODOLOGY: A retrospective analysis was performed on a dataset of 918 patients with complete clinical informat...

A complete time–temperature–transformation diagram of the RTM6 epoxy resin used for aerospace applications: integrating cure kinetics, thermal degradation and curing-induced overheating

Abstract RTM6 is a monocomponent epoxy resin widely used in the aerospace industry, where it is processed by resin transfer molding and related liquid-composite-molding routes. Its time–temperature–transformation (TTT) diagram maps, as a function of cure temperature and time, the...

Clinical and Epidemiological Characteristics of Retrospective Single-Center Observational Study

Background: Bisphosphonate-related osteonecrosis of the jaw (BRONJ) is a severe adverse event associated with antiresorptive therapy, particularly bisphosphonates, and represents a significant challenge in oral and maxillofacial practice. This study aimed to characterize the epid...

Study-Specific Morphological Signs of Non-Carious Tooth Surface Loss in Second Permanent Molars and Caries Experience in a Clinical Sample of Adolescents from Southwest Romania: A Multicenter Cross-Sectional Study

Background/Objectives: Morphological signs of non-carious tooth surface loss are clinically heterogeneous, and their prevalence depends strongly on the diagnostic framework and threshold used. This exploratory secondary analysis evaluated a study-specific combined morphological o...

Spermatocytic Tumor Arising in a Cryptorchid Testis: A Case Report and Narrative Review

Background: Spermatocytic tumor (ST) is a rare non-GCNIS-derived testicular germ cell neoplasm that predominantly affects older men and generally follows an indolent course. Its occurrence in a cryptorchid testis is exceptionally uncommon. Methods: A narrative literature review w...

Romanian Tourists’ Attitudes Towards the Oltenia Region Ecotourism in the Context of Sustainable Territorial Development

National parks, such as Domogled-Valea Cernei and Cozia, alongside protected areas like the Mehedinți Plateau Geopark or the Field of Lapiezuri in Ponoare, represent key assets for attracting tourists interested in nature and sustainability. This study investigates how tourists p...

Electrical and Apparent Compressive Response of Silver-Loaded Honey–Gelatin Soft Composite Membranes

Honey–gelatin–water composite membranes containing silver microparticles (SmPs) are investigated as soft pressure-responsive materials with potential applications in low-pressure sensing, including biomedical monitoring, and in tunable capacitive components. Three compositions, w...

On the weak solvability of a class of variable exponent systems

Abstract We use a variational approach based on the mountain-pass theorem to prove the existence of weak solutions for nonlinear variable exponent systems with homogeneous Dirichlet boundary conditions. The class of systems discussed here is governed by Leray-Lions type operators...

Bilateral-Asymmetry-Aware Multiple-Instance Learning for Breast Cancer Classification on Chest CT

Incidental breast abnormalities may be visible on chest computed tomography (CT), although breast tissue is frequently outside the primary diagnostic focus of these examinations. This proof-of-concept study developed and internally evaluated a bilateral-asymmetry-aware multiple-i...

Surgical Complexity and Postoperative Outcomes in Recurrent Versus Primary Incisional Hernias Following Elective Retromuscular Repair: A Retrospective Cohort Study

Background/Objectives: Recurrent incisional hernia remains a major challenge in abdominal wall surgery and is frequently associated with increased surgical complexity and adverse outcomes. However, its role as a distinct surgical entity and its cumulative operative impact remain...
