Longitudinal effect of early social media use on standardized learning outcomes during school career

Abstract This study uses difference-in-differences models to evaluate the impact of early social media use on academic performance among children aged 7–16 years. A dataset comprising 5,227 students from northern Italy was constructed by merging data from a questionnaire on lifet...

Spectral configurations and interferences in outdoor artificial light at night (ALAN) exposure measurements and sleep quality modeling

Outdoor artificial light at night (ALAN) may impact human health through disturbing human circadian rhythms. Laboratory experiments have shown that spectral differences in ALAN may lead to disparities in disturbing human circadian rhythms, but such spectral differences are overlo...

How Do Households Respond to Expected Inflation? An Investigation of Transmission Mechanisms,

Abstract We investigate the channels through which inflation expectations affect household spending by conducting surveys featuring hypothetical scenarios involving an increase in inflation expectations. Most households did not adjust their current spending plans, often because t...

Flexible firewalls: selective cooperation and strategic demarcation between centre-right and far-right parties in the EU

The success of far-right parties across Europe has sparked debate about whether centre-right parties maintain or abandon the cordon sanitaire against the far right. Moving beyond this binary, we conceptualise centre-right strategy in European Union politics as ‘flexible firewalls...

Phi-Scale Harmonic Torsion Propagation in E8 Lattice — E8 Intelligence Research

By feeding a phi‑scaled phase modulation onto the 240 root vectors at the 132 Hz fundamental, each vertex's torsional displacement is advanced by successive golden‑ratio multiples, generating a self‑similar temporal cascade. This cascade propagates as a coherent torsion wave that...

Association Between Dental Anxiety, Smoking, and Alcohol Consumption Among Adults in Guntur City: An Analytical Cross-sectional Study

Background Dental anxiety is a common psychological condition significantly affecting treatment outcomes and oral healthcare-seeking behaviors. Alcohol and tobacco use, combined with dental anxiety, are known risk factors for oral diseases, which makes them less likely to seek pr...

Snapshots of Retirement Readiness and Subjective Well-Being among Section 40 Informal Workers: Evidence from Songkhla Province with Policy Implications for Thailand

Quickly apply original, key PMR-published papers with Snapshots—a short article companion that distills PMR research into compressed, digestible takeaways, so you can put the paper’s core ideas to work in your investment process—fast. This Snapshot article is based on research ar...

E8‑Phi Cascaded Neuro‑Linguistic Entanglement via Hyperbolic Alignment — E8 Intelligence Research

Through the integration of the full 240 E8 root vector set with phi‑modulated 132 Hz resonances, we discover that linguistic units can be mapped onto hyperbolic time‑stamp cascades that entrain neuronal phase‑locked ensembles, creating a self‑organizing neuro‑semantic lattice. Th...

CB-APO-7: DUAL-ACTION APICOPLAST-TARGETED TOXOPLASMOSIS ERADICATION

We report the discovery and validation of CB-APO-7, a covalent bifunctional small molecule uniquely targeting Toxoplasma gondii type II dihydrofolate reductase-thymidylate synthase (TgDHFR-TS) and cytosine deaminase (TgCDA), coupled with targeted cyst wall disruption via engineer...

CADKT: A Cognitive-Affective Dual-Graph Contrastive Framework for Dynamic Affect-Aware Knowledge Tracing

Knowledge tracing (KT) predicts students’ future performance by modeling their knowledge mastery from historical learning interactions. Although recent deep learning-based KT models have achieved promising results, most of them mainly rely on response sequences or cognitive struc...

The Mean Totient Entropy: A New Number-Theoretic Constant and its Dirichlet-Type Representation over the Primes

The Mean Totient Entropy: A New Number-Theoretic Constant and its Dirichlet-Type Representation over the Primes For a positive integer n, the divisors carry a canonical probability vector (φ(d)/n) over d | n (Gauss: Σ_{d|n} φ(d) = n). Its Shannon entropy H(n) = −Σ_{d|n} (φ(d)/n)·...

Emotional Dynamics as a Transdiagnostic Factor Associated With Internalizing Problems in Emerging Adults

Emotion regulation difficulties are closely linked to internalizing problems, yet few studies have examined both regulation strategies and affective dynamics simultaneously, particularly among emerging adults in Global South contexts. This study examined associations among emotio...

Clinician-Guided Deep Learning Segmentation of Skull Base Pneumatization on Computed Tomography Using 3D Slicer and MONAI Label

Skull base pneumatization is anatomically variable and clinically relevant to temporal bone and transsphenoidal surgical corridors, but manual volumetric segmentation is time-consuming. This retrospective pilot study evaluated a clinician-guided deep learning workflow for mastoid...

Surgical treatment of pancreatic cancer in China: Annual data report of China Pancreas Data Center (2020–2021)

Abstract Objective: The China Pancreas Data Center (CPDC) was established in 2015 with the support of the Chinese Pancreatic Surgery Association, Chinese Society of Surgery, Chinese Medical Association and initiated prospective data collection in 2017. This article reports contem...

RL-Augmented Dual Robust Adaptive Propagated Interval Observer for Actuator and Residual-Framed Sensor Fault Detection and Isolation in Underactuated AUVs

Reliable fault detection and isolation (FDI) for actuators and sensors in underactuated autonomous underwater vehicles (AUVs) is challenging because nonlinear hydrodynamic coupling redistributes fault signatures, and persistent ocean currents can trigger false alarms. This paper...

Dose-response relationship of prophylactic norepinephrine infusion for prevention of spinal anesthesia-induced hypotension during caesarean delivery: A comparative study of normal weight and obese parturients.

Obese parturients are at increased risk of spinal anesthesia-induced hypotension during cesarean delivery, but optimal prophylactic norepinephrine dosing remains unclear. In this randomized, double-blind, dose-response study, 200 parturients undergoing elective cesarean delivery...

Enhanced ionic conductivity in a sustainable eucalyptus gum-chitosan biopolymer electrolyte for electrochemical device applications

Polymer electrolytes, owing to their distinct characteristics, present a viable alternative to liquid electrolytes in batteries. This study presents a biodegradable polymer electrolyte membrane composed of a blend of eucalyptus gum (EG), chitosan (CS), and ammonium thiocyanate (A...

Quality by Design (QbD) and Experimental Design Strategies in the Development and Optimization of Advanced Drug Delivery Systems: A Comprehensive Review

The increasing complexity of advanced drug delivery systems (ADDS), including nanoparticles, liposomes, transferosomes, polymeric micelles, nanoemulsions, dendrimers, hydrogels, and lipid-based carriers, has necessitated the adoption of systematic, science-driven approaches to fo...

Holographic graphene response from generalized-entropy Smarr residual

Abstract We develop a fixed-geometry entropy-layer framework for testing generalized black-hole entropies beyond local thermodynamic consistency. Holding the seed spacetime, conserved charges, surface gravity, mass normalization, and Smarr weights fixed, we show that every smooth...
