A Dual‐Modal Wearable PPG Smartwatch with AI‐Enhanced Correction for High‐Accuracy and Continuous AF Burden Assessment

open access: yesAdvanced Science, EarlyView.
ABSTRACT Atrial fibrillation (AF) increases the risk of stroke and heart failure, yet accurate quantification of AF burden in daily life remains difficult. Although smartwatch photoplethysmography (PPG) supports continuous monitoring, complex rhythms and signal noise can impair burden estimation.

Self‐Assembly of Antigenic Peptide Nanofibrils Templates the Growth of Silica Nanoparticles for Nanovaccines

open access: yesAdvanced Science, EarlyView.
Antigenic peptides Aβ42 and E7 self‐assemble into nanofibrils; APTES and TEOS induce SiO2 NP formation on these fibrils to form SiO2@fibril nanovaccines, which activate BMDCs in vitro. In vivo, SiO2@Aβ42 fibril nanovaccines alleviate AD symptoms and clear Aβ42 plaques in APP/PS1 mice, and SiO2@E7 fibril nanovaccines inhibit tumor growth and promote ...

Cognitive Load and Learned Helplessness: Examining the Psychological Consequences of Instructional Demands

open access: yesJurnal Theorems (The Original Research of Mathematics)
This study investigates the relationships between the dimensions of cognitive load—namely, intrinsic, extraneous, and germane—and learned helplessness among students. The study is grounded in the premise that students’ learning difficulties may not arise

Mechanical Intelligence in Bone Regeneration: Bridging Material and Cellular Memory for Enhanced Healing

open access: yesAdvanced Science, EarlyView.
Mechanical intelligence reframes bone regeneration as a time‐dependent coupling between material and cellular memory. Biomaterials store and release mechanical history, while cells retain prior cues and remodel the repair niche. Matching these memories to healing stages may guide stage‐specific scaffolds, sensing‐assisted prediction, mechanical dosing,

Oral Delivery Systems for Food‐Derived Bioactive Peptides: Enhancing Stability, Bioavailability, and Health Benefits

open access: yesAdvanced Science, EarlyView.
Advanced delivery systems—including nanoparticles, nanoemulsions, liposomes, and hydrogels—protect food‐derived bioactive peptides from gastrointestinal degradation and bitterness. These systems enable pH‐responsive release, enhance intestinal absorption, and improve therapeutic efficacy against oxidative stress, metabolic disorders, cancer, and ...

NSD2 Coordinates the Neurogenic‐to‐Gliogenic Transition via H3K36me2‐Dependent Activation of the EGFR‐ERK Pathway

open access: yesAdvanced Science, EarlyView.
NSD2 coordinates the neurogenic‐to‐gliogenic transition in the developing neocortex through H3K36me2‐dependent activation of EGFR–ERK signaling. Loss of NSD2 disrupts astroglial and oligodendroglial development, whereas ERK activation rescues gliogenic defects in vitro and in vivo.

Reducing Intrinsic Cognitive Load in Complex Learning Such as Flight Training That Involves Both Cognitive and Psychomotor Tasks

open access: yes, 2014
Flying an aircraft requires processing or considering great number of inputs and an ability to link these data to a massive amount of information in order to interpret them. As a result, flight training imposes a high intrinsic cognitive load. The focus of this research was to investigate the effect of decreasing intrinsic cognitive load for complex ...

Human Dental Pulp Stem Cell Secretome Restores Ischemic Stroke–Impaired Motor and Cognitive Functions by Reprogramming Redox and Inflammatory Signaling

open access: yesAdvanced Science, EarlyView.
Human dental pulp stem cell secretome emerges as a cell‐free therapeutic strategy for ischemic stroke by reprogramming redox and inflammatory signaling. hDPSC secretome‐derived antioxidant and immunomodulatory factors suppress the TLR4–NOX–ROS–NF‐κB axis, reduce microglial inflammatory responses and apoptosis, and promote neurogenesis, angiogenesis ...

Mapping cognitive load profiles in realistic mathematics education: A study with aerospace engineering students

open access: yesJurnal Elemen
Although Realistic Mathematics Education (RME) promotes deeper conceptual learning, empirical evidence mapping different types of cognitive loads in university engineering mathematics is limited.
