Earliest simultaneous multi-color optical observations of GRB 230328B: from 41 seconds to the host-galaxy identification

Abstract We present a multiwavelength study of the long-duration gamma-ray burst GRB 230328B, combining prompt γ-ray observations with exceptionally early simultaneous optical photometry and extensive X-ray, radio, and host-galaxy follow-up. NUTTELA-TAO began simultaneous g′r′i′...

Neanderthal’s heel: How the Neanderthal’s external calcaneal shape uniquely differs from that of modern humans

Neanderthals exhibit unique morphological adaptations in their calcaneus compared to Homo sapiens , shedding light on distinct evolutionary pressures and functional requirements shaping their respective foot anatomy. This study assesses which calcaneal traits represent plesiomorp...

Assessment of the Dissipative Properties of Viscoelastic Hollow Cylindrical Bodies with Filler During the Propagation of Natural Waves

Searching by numerical simulation for structures with optimal damping properties among viscoelastic hollow cylindrical bodies with a filler is usually associated with a large amount of computation. Formulating the mechanical problem as one of natural vibrations and natural wave p...

Key management practices controlling yield performance and nitrate leaching in a grass-clover based organic crop rotation

Organic farming is frequently discussed as a strategy for mitigating nitrate leaching, especially in water protection areas. The effectiveness of nitrogen (N) management practices within organic crop rotations requires evaluation to balance yield performance with nitrate leaching...

Integrated Multi-Row Onion Production Under Contrasting Seasonal Conditions: Seeder Optimization, Nutrient Management, Crop Protection, and EIQ-Adjusted Sustainability

Reliable establishment of direct-seeded onion requires coordinated control of sowing geometry, nutrient supply, crop protection, and resource use. This study combined Hartley-4 optimization of a four-section, multi-row ridge seeder with a two-year randomized complete block experi...

Explainable Multi-Objective Quantum-Inspired Fuzzy Optimization of Rule Bases for Scalable Load Balancing in Multi-Factor Computing Environments

The rapid growth of cloud and distributed computing systems has increased the complexity of real-time request distribution under dynamic and multi-factor conditions. In such environments, load-balancing decisions must simultaneously consider uncertain and interdependent parameter...

Long-Lifespan Turbostratic Graphene Field Emitters for High-Power Applications

Abstract Cold cathodes offer heater-free, instantly switchable electron sources, but conventional sharp-tip designs often degrade under continuous thermal loads, limiting high-power applications. We overcome this with a freestanding, edge-emitting turbostratic graphene film (GF)....

A Closed-Loop Measurement Study of Runtime Governance in AI-Driven Smart Building Climate Control

Which runtime governance mechanisms reduce physical risk when a learned controller drives a building’s climate, and under what conditions? We develop a closed-loop software-in-the-loop testbed in which a setpoint model trained on real occupancy data drives a physics-based thermal...
