Subanesthetic nitrous oxide alters large-scale network organization and insula connectivity during visual stimulation

Pharmacological agents that alter consciousness, including classic psychedelics and non-classic agents such as nitrous oxide, are known to affect multiple domains of conscious experience, including visual perception. While most neuroimaging studies rely on resting-state data to c...

PI3K/AKT signaling pathway: molecular crossroads in tumorigenesis and therapeutic innovation

The PI3K/AKT signaling pathway serves as a pivotal regulatory hub that governs essential cellular processes, including growth, proliferation, metabolism, survival, and migration. In the context of tumorigenesis and cancer development, aberrant activation of this pathway drives ma...

Interference Analysis and Performance Improvement based on RAN Sharing in LTE-R and PS-LTE Coexistence Environment

우리나라는 700MHz 대역 LTE 기반으로 PS-LTE, LTE-R, LTE-M을 통합 운영하는 공공무선통신망 정책을 추진 중이다. LTE-R은 2017년 원주–강릉 구간을 시작으로 구축되어 2027년까지 전 철도 노선 적용을 목표로 한다. LTE-R(UL 718–728MHz, DL 773–783MHz)은 PS-LTE와 동일 주파수를 공유하여 동일채널...

Profiles of stressful life experiences in pregnancy: a latent class approach linking early childhood adversity, intimate partner coercive control, and material hardship to adverse birth outcomes

Acute antenatal stressful life events (SLEs) during pregnancy are well-established risk factors for adverse birth outcomes. However, little is known about how distinct constellations of antenatal SLEs, shaped by early adversity, material hardship, and intimate partner coercive co...

Comparative Analysis of Mass and Number Concentration Characteristics of Non-Exhaust Particulate Matter (Airborne Wear Particles) Generated from Wheel-Rail Contact

도시 철도 터널 공기는 철도 차량 운행 중 발생하는 비배기 미세먼지, 특히 휠-레일 접촉에서 발생하는 미세 마모 입자에 의해 심하게 오염되어 있다. 본 연구에서는 이러한 휠-레일 접촉 미세 마모 입자의 발생 특성을 규명하기 위하여 Twin-disk rig를 활용한 모사 시험을 수행하고, 발생 입자의 수...

ROX index and NEWS2 for 28-day mortality prediction in emergency department patients with acute dyspnea: a prospective observational study

Acute dyspnea is a frequent and high-risk presentation in emergency departments (ED), requiring rapid identification of patients at increased risk of deterioration and mortality. This study aimed to compare the accuracy of the Respiratory Rate–Oxygenation (ROX) index and National...

Development and validation of an interpretable machine learning model for predicting ICU prognosis in critically ill patients with invasive pulmonary aspergillosis: a multicenter study

Invasive pulmonary aspergillosis (IPA) is associated with elevated mortality among intensive care unit (ICU) patients. Early prognostic risk stratification is of great importance; however, validated clinical tools remain limited. This study aimed to develop and validate an interp...

The Chronic Psychological Burden of Urban Noise and Light Pollution: A Cross-Sectional Study of a Major Crossroads in Daegu, South Korea

Background: Residential environmental stressors, such as noise and light pollution, significantly impact psychological well-being.While individual sensitivity and cognitive perception are known to influence environmental annoyance, how these factors operate differently across aud...

Supervision best practices to train and retain the early career behavioral health workforce: a scoping review and expert interviews

The U.S. behavioral health system is experiencing critical workforce shortages. Early career behavioral health clinicians (ECBHCs)—professionals with master’s or doctoral degrees and one to three years post-graduate experience—face unique challenges in obtaining required supervis...

Environmental Risk Assessment of Triphenyl Phosphate in Freshwater, Sediment, and Soil

Background: Triphenyl phosphate (TPP) is an organophosphate flame retardant known to accumulate in the environment, including in surface water, sediment, and soil, ultimately resulting in toxicity.While continuous monitoring studies on TPP have been reported, ecological risk asse...

The Economics of AI Governance: Evaluating Data Sovereignty, Platform Monopolies, and the Digital Personal Data Protection Act (DPDPA)

This paper evaluates the economic and strategic implications of generative artificial intelligence architectures on market competition and digital asset ownership in 2026. Focusing on the intersection of platform economics and data governance, the study examines how modern founda...

Determinants of self-esteem among children in Jordan

Self-esteem is an important factor affecting personality development. School-aged children can have lower self-esteem levels compared to people of other age groups and it can be influenced by several factors which vary across cultures. This study aimed to assess self-esteem and e...

C5aR1-positive PMN-MDSC-induced angiogenesis limits the efficacy of radiotherapy combined with Anti-PD-1 immunotherapy

Radiotherapy (RT) combined with Anti–PD-1 immunotherapy (RT + Anti-PD-1) offers synergistic potential in the treatment of colorectal cancer (CRC). However, RT + Anti-PD-1 often fails to be effective in some patients with CRC, because a subset of tumors exhibits limited responsive...

Occupational creativity and liability to psychiatric disorders: a bidirectional Mendelian randomization study

The long-standing “mad genius” hypothesis proposes a link between creativity and psychiatric illness, but existing genetic evidence has largely relied on genetic correlations and polygenic associations rather than approaches designed to evaluate directional effects. We conducted...

Synchronization Hub Protocol

Autonomous LLM agents acting on external systems routinely operate on stale or hallucinated beliefs about environment state, and dominant agent architectures for example "ReAct" in particular — provide no independent mechanism to detect this before an action is executed by the LL...

Risk of Recurrence in Patients with HR+/HER2− Early Breast Cancer: A Podcast

Within 20 years of diagnosis, up to 27% of patients with hormone receptor-positive/human epidermal growth factor receptor 2-negative early breast cancer will experience recurrence, despite standard-of-care treatments. Of these recurrences, approximately half will occur within 5 y...

Emergy-based Evaluation of the Sustainability of Oyster Aquaculture in Korea

에머지 평가법을 적용해 우리나라 연승수하식 굴 양식의 지속가능성을 평가하고, 굴 양식 해역 생태계가 수산물 공급서비스에 순수하게 기여하는 비율(자연기여율)을 산정했다. 굴의 양성·채취 및 박신 과정에 투입된 에머지 총량은 2.64×1017 sej였으며, 이 중 재생가능에머지는 8.1%, 외부구입 에머...

Detection Patterns and Temporal Dynamics of Multiple Pathogens in Wastewater Using a TaqMan Array Card
