Small, EarlyView.ABSTRACT The rapid expansion of the Internet of Things (IoT) and wearable electronics necessitates sustainable power sources to replace the limited electrochemical battery. While mechanical energy harvesting offers a promising solution, traditional harvesters face challenges of irregular and low−frequency environmental sources. This review presents the

Greenway development and gentrification
Southern Economic Journal, EarlyView.Abstract This paper presents research on expanding access to green spaces in developed areas. Critics claim greenway projects lead to gentrification by increasing the demand for housing and pushing out residents in nearby neighborhoods. We look for evidence of this phenomenon using a sorting model and panel data on aggregate populations in Atlanta ...

steel research international, EarlyView.Surface reconditioning through mechanical and electrochemical polishing is shown to extend the fatigue life of predamaged 42CrMo4 steel by over 12 times. By removing ≈100 μm of surface material, surface‐driven fatigue damage is mitigated. This study introduces a reuse potential metric to evaluate fatigue recovery and support sustainable steel reuse. To

Enhancing LoRA Model Serving Capacity via Adaptive Operator Scheduling for Multi-Tenancy on GPU
IEEE AccessLow-Rank Adaptation (LoRA) has garnered increasing attention for effectively fine-tuning large language models (LLMs) with limited resources. Nonetheless, conventional approaches that cater to multiple LoRA models independently lead to redundant ...

steel research international, EarlyView.The study investigates the reoxidation behavior of DRI pellets (Midrex and H2‐reduced) under realistic conditions, considering the test parameters of temperature, humidity, storage duration, particle size (including fine fraction), and container geometry. The samples are analyzed based on mass changes.

Structural Concrete, EarlyView.Abstract After a blossoming pre‐World War II (WWII) period, the concrete construction industry in then‐socialist Hungary existed in a relative isolation from the Western World during the mid‐20th century. In this paper, we focus on the body of work of one of the then newly established state‐owned design offices, IPARTERV, to show how the isolation ...
