Planning energy adequacy for a renewable New England: Multi-decade weather, short- and long-duration storage, and grid-interactive electric vehicles

This study evaluates how planning horizon length, storage technology mix, and firm capacity affect resource adequacy in a high-renewable New England electricity system. Using 44 years of hourly wind, solar, and demand data, the analysis optimizes least-cost portfolios under diffe...

Building SME resilience in a circular economy transition: An integrated model of firm capabilities and institutional support in Vietnam

The shift from a linear to a circular economic (CE) model presents challenges and significant opportunities, demanding a new understanding of firm-level resilience. Based on an integrated theoretical framework drawn from resource-based and social capital theories, this study exam...

Research on the Application and Effect Analysis of Deep-network Learning-based Image Recognition Optimization Algorithm in the Field of Advertisement

In the field of apparel advertising, the accuracy of image style recognition is crucial for accurate marketing and user experience. Traditional manual feature extraction methods are inefficient and have limited accuracy. In this paper, we innovatively propose a recognition method...

Discovery and engineering of enzymes for new-to-nature photobiocatalysis

Photobiocatalysis integrates enzymatic catalysis with photochemistry, enabling challenging radical transformations with high selectivity under mild conditions. Early developments in this field were largely driven by the discovery that enzyme-bound cofactors can form photoactive c...

Low-loss dielectric radome with RFID for intelligent scanning in sub-THz, future autonomous defense systems

The proposed antenna design incorporates a 0.3 mm thick Roger substrate, a 0.00125 mm thick patch, and a cylindrical hollow radome made of Preperm HF H1500 material. The radome encloses a 1 × 11 linear array with a radius of 5.40 mm without affecting its radiation characteristics...

Analyzing Factors Influencing Shared E-Scooter Towing Based on Building-Adjacent Characteristics : A Case Study of Gangnam-gu, Seoul

Dockless 방식의 전동킥보드는 대중교통의 First Mile·Last Mile 수단으로 활용되고 있으나, 반납 위치에 대한 물리적 제약이 없어 보도나 시설 출입부에 무단 방치되는 사례가 지속되고 있다. 서울시는 2021년 시민 신고 기반 견인제도를 시범 운영한 후 2022년 전면 시행하였으며, 지하철역 등 인구...

CAP-UNet: frequency-decoupled and geometry-aware attention for medical image segmentation across multiple imaging modalities

Accurate medical image segmentation is frequently hampered by pervasive challenges such as severe visual camouflage, extreme scale variations, and highly irregular anatomical boundaries across diverse imaging modalities. To address these challenges, we propose CAP-UNet, a geometr...

Integrated experimental, machine learning and life cycle assessment of basalt and polypropylene fiber-reinforced ferrosilicon slag-based geopolymer concrete

The construction industry faces increasing pressure to reduce greenhouse gas emissions, conserve natural resources, and promote the utilization of industrial by-products, as ordinary Portland cement (OPC)-based concrete remains one of the largest contributors to global carbon emi...

Artificial intelligence virtual bone organoids (AIVBOs)

Global population aging has made skeletal disorders a major threat to human health. Solid bone organoids reproduce skeletal physiology and pathology more faithfully than traditional models, yet remain limited in standardisation, real-time monitoring, and high-throughput use. Inte...

Improving Detection Performance via R-VAE-Based Synthetic Data Augmentation for Indoor Fire Scenarios

본 논문은 실내 화재와 같은 사고 데이터의 극심한 불균형 및 희소성 문제를 해결하기 위한 효율적인 합성 데이터 생성 및 증강 방법론을 제안한다. 기존 VAE나 GAN, Diffusion 모델과 같이 이미지 전체를 생성하는 방식이 아닌, 실내 CCTV의 배경 불변성(Background Invariance)을 활용하여 배경을 분...

Incidental vocabulary learning through reading in multilingual primary school Children: The Roles of reading Comprehension, contextual Diversity, and contextual informativeness

Incidental word learning through reading plays a central role in vocabulary development. Multilingual children, for whom English is an additional language, bring relevant language-learning experience to the task of learning new words through reading in English. However, it is not...

Surface DBD plasma functionalization of the interior of PVC and PTFE tubes: effects on surface properties and environmental safety assessment of leaching

This study investigates the internal surface modification of polytetrafluoroethylene (PTFE) and poly(vinyl chloride) (PVC) tubes using a liquid-electrode surface dielectric barrier discharge (SDBD) plasma system. The approach addresses the “hollow body problem” by enabling unifor...

A pilot study of circulating DPP3 and renin to identify high-risk phenotypes and mortality in septic shock

Sepsis and septic shock are life-threatening conditions associated with high mortality and limited treatment options. Rapid identification of patients at risk for worse outcomes and/or targeted therapeutics are needed. Elevated levels of renin and dipeptidyl peptidase 3 (DPP3) in...

A Hardware-Based Architecture for Prioritizing Multimodal Sensing Data in Disaster Environments

In this paper, we propose a novel hardware architecture specifically designed to enable real-time response in disaster environments, where rapid decision-making and low-latency processing are critical. Our approach focuses on optimizing a GAN-based radar voice imaging system, whi...

Advanced 3D Object Detection with Tone-Mapping Enhanced Fine Disparity R-CNN

3D object detection is one of the key techniques in autonomous driving. However, existing 3D object detectors will likely be impaired under low illumination conditions and show poor performance on small object detection. To resolve this limitation, this paper proposes a tone mapp...

Clinicopathological Characteristics and Outcomes of Primary Parotid Gland Carcinomas in the Czech Republic: a Multicenter Retrospective Cohort Study of 453 Surgically Treated Patients
