Physics of galactic colliders: high speed satellites in LCDM vs MONDian cosmology

open access: yes, 2009
The statistics of high speed satellite galaxies, as reported in the recent literature, can be a powerful diagnosis of the depth of the potential well of the host halo, and hence discriminate between competing gravitational theories.

Dual-channel representation learning with wind speed correction factor for enhanced wind power forecasting

open access: yesEnergy and AI
Wind power forecasting (WPF) accuracy is fundamentally constrained by two critical challenges. First, the high-order nonlinear relationship between wind speed (WS) and power (WP) substantially amplifies errors inherent in numerical weather prediction ...

Bumblebees gain fitness through learning [PDF]

open access: yes, 2007
Despite the widespread assumption that the learning abilities of animals are adapted to the particular environments in which they operate, the quantitative effects of learning performance on fitness remain virtually unknown. Here we evaluate the learning

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

open access: yesFEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Optimization of Cutting Parameters to Minimize Tooling Cost in High Speed Turning of SS304 using Coated Carbide Tool using Genetic Algorithm Method

open access: yesInternational Journal of Engineering Materials and Manufacture, 2016
High speed turning (HST) is an approach that can be used to increase the material removal rate (MRR) by higher cutting speed. Increasing MRR will lead to shortening time to market.

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Research on forging forming force in the composite technology of cross wedge rolling (CWR) and forging for universal joint fork

open access: yesMetalurgija, 2019
In this paper,the forging process of universal joint fork of automobile transmission shaft is simulated and the change of forming force of die forging is studied on the basis of the blank produced by cross wedge rolling (CWR).
