Elymus arasbarani sp. nov. (Poaceae; Triticeae), genus Elymus sect. Elytrigia from Arasbaran, northwest Iran

During a biosystematics study of the Iranian species of the genus Elymus in 2022–2024 a new species for the genus Elymus L. was found in the Arasbaran region of northwest Iran. The new species is morphologically close to Elymus repens and Elymus elongatiformis but differs in term...

Experimental investigation of salt removal from medium-grade Zubir Mushref crude oil using ultrasonic and chemical methods: process optimisation and performance assessment

Crude-oil desalting limits the movement of inorganic salts into refinery equipment and therefore supports corrosion control and reliable operation. In this laboratory study, crude-oil demulsification was examined using RP6000, ultrasonic treatment, and a combined ultrasonic–chemi...

Beyond Quantization: Self-Supervised Speech Representation Learning via Masked Hilbert Envelope Prediction

Current self-supervised speech models typically avoid predicting raw time-domain waveforms directly because fast phase shifts cause instability. To bypass this, popular methods use vector-quantized codebooks, multi-stage clustering, or teacher networks, but these approaches can s...

The lived experiences of social stigma among individuals with multiple sclerosis: a qualitative phenomenological study using Colaizzi’s method

Multiple sclerosis (MS) is a chronic neurological disease associated with physical, psychological, and social challenges. Beyond the burden of neurological symptoms, individuals with MS may experience social stigma that affects their identity, relationships, emotional well-being,...

Dual-therapeutic niraparib-loaded chitosan nanoparticle–alginate hydrogel with adipose-derived stromal cells promotes functional and histological recovery after spinal cord injury

Background: Spinal cord injury (SCI) triggers oxidative stress, inflammation, and progressive neurodegeneration. Methods: Here, we developed a dual-therapy composite hydrogel that integrates niraparib-loaded chitosan nanoparticles (NICNPs) and adipose-derived stromal cells (ASCs)...

Cross-dataset transcriptomic analysis identifies oxidative Stress–inflammation gene networks modulated by nutrigenomic interventions in Parkinson’s disease

Abstract Inflammation and oxidative stress (OS) are key to Parkinson’s disease (PD). We performed a cross-dataset integrative transcriptomic analysis to identify OS- and inflammation-related hub genes consistently dysregulated in PD and to explore gene–compound relationships usin...

A numerical investigation of three-dimensional fluid flow in the bipolar plate of a PEMFC with novel configurations of serpentine flow channels

This study investigates modified serpentine flow channels for PEMFCs to reduce pressure loss and secondary-flow effects at bends. Conventional, symmetric, and hybrid configurations with different bend geometries were analyzed using three-dimensional CFD simulations based on press...

Codec-Invariant Audio Watermarking via Hierarchical Residual Injection (Extended Abstract)

The rapid adoption of discrete neural audio codecs (e.g., EnCodec) in large language models necessitates codec-invariant speech watermarking to track synthetic data provenance. However, current continuous-domain paradigms inject payloads as surface-level waveform perturbations, w...

Refining the Kano model: a behaviour-based approach to reclassifying questionable attributes

Purpose Questionable attributes in the Kano model – arising from inconsistent functional and dysfunctional customer responses – are typically discarded in prior studies, resulting in incomplete interpretation of customer needs. This study introduces a methodological refinement to...

Association between body mass index and medial longitudinal arch parameters: a systematic review and meta-analysis of observational studies

Foot structure and function are influenced by biomechanical and anthropometric factors, with Body Mass Index (BMI) proposed as an important determinant. Elevated BMI may be associated with alterations in the medial longitudinal arch (MLA); however, existing evidence is inconsiste...

Towards human-centered and efficient video synthesis: a survey of multimodal diffusion models

Abstract Multimodal video diffusion models have emerged as transformative tools for controlled video synthesis, integrating text, images, audio, and pose sequences to generate semantically meaningful content. Despite significant advances, critical gaps persist in temporal consist...

A hybrid drought index prediction framework under climate change scenarios by equipping index fusion with an individual artificial intelligence method

Due to the multidimensional nature of drought and the limitations of single-variable indices in capturing combined meteorological, hydrological, and socioeconomicimpacts, predicting hybrid droughts is valuable insights for water resource management. This study proposes an Index-f...

Advances in regenerative medicine and their impact on cancer therapy and tumor microenvironment modulation

Regenerative medicine has emerged as a transformative field that can augment cancer therapy by leveraging stem cells, gene therapy, and tissue engineering to address limitations of conventional treatments. This review synthesizes recent advances in cell-based therapies, biomateri...

A novel FPGA-based garbled circuit accelerator for secure two-party multiplication (GCMult)

Privacy-preserving function execution is crucial for applications such as cloud-based machine learning and IoT. While garbled circuits offer a viable solution, they suffer from high computational and communication costs. Multiplication, a fundamental operation in computing, plays...

Geotechnical performance of a two-row grout curtain in karstified limestone–marl: insights from stage-grouting and clay-filled discontinuities at Chamshir RCC Dam

Abstract Curtain grouting is widely applied for seepage control in dam foundations; however, quantitative performance assessment in heterogeneous karstified formations remains methodologically challenging. This study presents an integrated evaluation of a two-row grout curtain co...
