A Calibrated Building Energy Simulation-Driven Framework for Balancing Embodied and Operational Carbon in the Transition to Zero-Emission Buildings

Educational buildings account for approximately 17% of the building sector’s energy consumption, making them critical for zero-emission building (ZEB) strategies. With students spending over 50% of their time indoors, life-cycle carbon assessments and targeted retrofitting are es...

Genome-Wide Identification, Evolutionary Analysis and Comprehensive In Silico Characterization of the GPAT Gene Family in Sunflower (Helianthus annuus L.)

Glycerol-3-phosphate acyltransferase (GPAT) are enzymes involved in glycerolipid biosynthesis and play a key role in plant growth, development, and abiotic stress responses. However, a comprehensive genome-wide and in silico analysis of the GPAT gene family in sunflower (Helianth...

Integrative Analysis of Genome Data Using Deep Embedded Clustering to Identify Population Stratification and Functional Gene Modules

AbstractIntroduction: Next-Generation Sequencing (NGS) data analysis faces computational challenges due to high dimensionality. Traditional clustering methods fail to capture biological complexity in human genetic variation. This study introduces Deep Embedded Clustering (DEC) fo...

Isolation, genomic characterization, and biocontrol potential of a bacteriophage cocktail against Staphylococcus aureus in milk

The objectives of this study were to isolate, characterize, and evaluate the biocontrol potential of Staphylococcus aureus -targeting bacteriophages in milk. From wastewater and raw milk samples, a total of 19 lytic phages were isolated. Among them SAKAY1298 and SAKAY1306 phages...

On Pell, Narayana and Padovan Languages and Their Generalizations

In this article, we study several languages associated with classical integer sequences such as the Pell, Narayana, and Padovan sequences, as well as various generalizations. Some of these languages arise naturally in the context of graph theory. We show that a subset of these la...

Machine learning-based winner prediction in elite kickboxing: a technical-tactical performance analysis

To develop and validate machine learning models for predicting match outcomes in elite kickboxing based on technical-tactical performance indicators and to identify the key variables distinguishing winners from defeated athletes. Video analysis was conducted on 142 elite kickboxi...

Theory of mind and social competence in preschool children with cochlear implants: relationships with language proficiency

This study examined receptive and expressive language proficiency, Theory of Mind (ToM), emotional expressiveness, and social competence in preschool-aged children with cochlear implants (CIs) and age-matched typically hearing (TH) peers. Thirty-two children with CIs and 32 TH ch...

The efficacy of suprascapular nerve radiofrequency and intra-articular steroıd injectıon in frozen shoulder treatment: randomızed controlled trial

Abstract Background This study aims to address the impacts of intra-articular steroid injection (IASI) alone versus the combination of suprascapular nerve (SSN) pulsed radiofrequency (PRF) and IASI on pain relief and improvement in shoulder range of motion (ROM) in patients with...

Co-Encapsulation of Indocyanine Green J-Aggregate and Paclitaxel in Biodegradable Polymersomes for Photoacoustic-Guided Chemotherapy

Abstract Treatment of solid tumors remains one of the biggest challenges in oncology. Targeted nanotherapeutics could significantly improve treatment efficacy and reduce side effects. However, their efficient implementation requires knowledge of pharmacokinetics (PK) and biodistr...

Artificial Intelligence in Thyroid Nodules and Cancer: Clinical Validation and Real-World Performance

Abstract Thyroid nodules are detected in a large proportion of adults undergoing high-resolution ultrasonography, yet only a minority harbor clinically significant cancer. The clinical problem is therefore not only cancer detection but calibrated risk stratification: avoiding del...
