Abstract The mechanism of thermally enhanced luminescence (TEL), such as thermally activated delayed fluorescence (TADF) and thermally stimulated delayed phosphorescence (TSDP), is of fundamental importance in the molecular design of emissive transition-metal complexes, as it can enable bright emission with enhanced radiative rate for high-performance organic light-emitting diodes (OLEDs). It is essential to resolve the...

Public perceptions of mangroves: a sentiment and topic analysis of global Twitter/X content
Abstract Social media has emerged as a prominent factor in shaping public perceptions. However, significant gaps remain in our understanding of the complex interplay between social media and human-nature relationships, including for mangrove ecosystems. We assessed how mangroves have been discussed and perceived on social media by analysing 649,495 Twitter/X posts between 2010 and 2022....
Effective plasmonic enhancement of up-conversion photoluminescence from a-NaGdF4:Yb3+,Er3+ nanoparticles by gold dendrites
Abstract The current paradigm of plasmon-enhanced up-conversion photoluminescence (PE-UCPL) lays in intimate coupling domains of noble metal and lanthanide-doped nanoparticles. An increase of incident electromagnetic field and radiative emission rates is the key reason for the UCPL enhancement by the primitive plasmonic architectures of metal nanospheres/nanorods/nanoshells. Based on the hypothesis of precise tuning surface plasmon...
A unified multimodal framework for chest X-ray retrieval and disease prediction for clinical decision support
Abstract Recent advances in medical imaging and natural language processing enable new opportunities for automated diagnostic support. Chest X-rays (CXRs) remain the most common imaging modality for screening pulmonary, cardiovascular, and systemic diseases; however, the growing volume of studies and free-text reports can overwhelm clinicians. We propose a unified multimodal retrieval and prediction framework that...
Isolation, structural re-elucidation of two active prenylated flavonoids from Morus alba L. twigs responsible for anti-inflammatory effects: an in vitro and in silico approach
Abstract Ethnobotanical relevance Morus alba L. has been reported to exhibit various pharmacological effects, including antipyretic, hepatoprotective, nephroprotective, antihypertensive, and anti-inflammatory activities, as well as benefits for sore throat relief and eyesight improvement in traditional medicine. Aim of the study This study investigates the anti-inflammatory potential of two prenylated flavonoids isolated from the twigs of Morus...
Characterizing particulate-bound mercury (PBM2.5) in multiple sites of Southeast Asia megacity: Insights from Hg relationships with carbonaceous components
Abstract Fine particulate-bound mercury (PBM2.5) is being recognized as a public health and environmental issue owing to its high capacity to bioaccumulate and long-range transport. This study investigates PBM2.5 at two urban sites Nguyen Van Cu (NVC) and Linh Trung (LT) and one rural site Can Gio (CG) in Ho Chi Minh City (HCMC) to assess...
A Hybrid Dynamic Gold Code Architecture Resilient to Side-Channel Analysis Attacks in 180-nm CMOS
Abstract This study presents a hardware countermeasure that integrates two distinct types of random number generators. Recently, several effective time-based countermeasures against side-channel analysis (SCA) have relied on FPGA-specific primitives, such as Xilinx Digital Clock Managers (DCM) and Mixed-Mode Clock Managers (MMCM). However, these solutions lack portability to ASIC platforms. To address this, we propose...
Prototethyan Tam Ky-Phuoc Son ocean subduction-rollback dynamics: Insights from Early Paleozoic
Abstract The Tam Ky–Phuoc Son Ocean in Central Vietnam, a southern branch of the Prototethyan Ocean, holds critical evidence of Early Paleozoic subduction processes in Southeast Asia. However, the polarity and tectonic evolution of its subduction system remain controversial. Here we present new petrographic observations, zircon U-Pb geochronology, in situ zircon Hf isotopes and whole-rock...
Establishment of a BALB/c Mouse Model for Photoaged Skin: Insights into UV-Induced Dermatological Changes
Abstract Background: Photoaging, primarily induced by prolonged ultraviolet (UV) radiation exposure, significantly alters skin structure and function, necessitating models for deeper understanding and intervention development. This study aims to establish a BALB/c mouse model for investigating photoaging, leveraging their haired skin and genetic consistency. Materials and methods: Six-week-old female BALB/c mice were subjected to repeated exposure to...
Structural optimization of stress-bearing structures of nearly incompressible problems under design-dependent pressure loads
Abstract An efficient and innovative method is presented for the stress-related structural topology optimization (TO) in coupled mechanical-pressure systems by leveraging flexible polygonal meshes. With a polytopal composite finite element approach, the volumetric locking in nearly incompressible materials is reduced. A fluid-flow-based model is built, in which a design-dependent pressure variable is introduced to capture...
