Use of Virtual Reality Technology for Training Standing Shooting, Postural Balance, and Rifle Stability in Biathlon: A Pilot Study
Psychology. Journal of the Higher School of Economics. 2025. Vol. 22. No. 3. P. 434–448.
Success in biathlon depends on physical fitness, psychophysiological parameters, and biomechanics. Key aspects include the speed and accuracy of shooting, which affect body oscillations and the stability of the "body-rifle" system. The level of stress, environmental conditions, and ski preparation are also important. This study is aimed to provide a thorough theoretical analysis of the factors affecting the standing shooting performance in biathlon, and to conduct a pilot study using VR to validate it as a training tool based on the observed parameters. This study utilized the Biathlon-2024 Virtual Environment, which simulated skiing and standing shooting in classical biathlon. This Virtual Environment is developed on Unity 3D platform and includes two stages: 1) VR skiing, 2) shooting. Subjects performed shooting at virtual targets, whereby the VR visualization fully simulated a biathlon shooting range. The results confirmed that stability of bodyrifle system is crucial for successful shooting in biathlon. It was observed that elite athletes demonstrate a better postural balance and a lower sway compared to beginners. The data analysis obtained with Antilatency system trackers showed a distinct correlation between the limb and rifle positions, which highlights the importance of a fine postural control and reaction time when shooting. The study emphasizes that success in biathlon depends not only on physical fitness and shooting techniques, but also on environment, psychophysiology, and individual attributes such as tremor. This therefore makes an integrated approach to athlete training essential for high performance.

Automated microscopic image analysis is essential for quantitative microbiology, yet manual acquisition and generic recognition models struggle with morphological variability and scene artifacts. We address both ends of this pipeline. First, we present a low-cost, open-source acquisition system, based on an Arduino UNO R3 microcontroller and NEMA 17 stepper motors, that automates focusing, magnification, and ...

DreamBooth-style personalization, which often relies on one or a few images, can memorize context (background, pose, lighting) rather than learning the subject’s identity, thereby reducing fidelity and limiting prompt-driven edits. P-LoRA (Probability LoRA) is introduced as a training-time modification that biases diffusion timestep sampling and utilizes importance weights, ensuring that the overall objective remains unchanged. ...

Numerous studies have provided compelling evidence that the probability distribution of avalanche sizes follows a power law, and that 1/f noise is present in the stochastic dynamics of landslides. We present a theoretical explanation of these phenomena within the framework of self-organized criticality theory, proposing a discrete-time model in the form of a sandpile cellular ...

A discrete-time model is presented for the self-organization of the X/Twitter social network to the edge of a phase transition, characterized by avalanche-like propagation of information in the network. The model is based on the analogy between the critical dynamics of the X social network and sandpile cellular automata with Manna rule on the Chung-Lu ...

The paper substantiates the concept of the existence of a “transvital Self”, a particular form of an individual’s existence beyond the apparent forms of vital function and the processes of reproducing self as a psychophysical integrity. The author uses the term “transvitality” (as in A. Akopyan’s “transvital meanings”) to more generally address this concept as ...

The concept of the I that is present in the scholarly and mundane consciousness is inwardly paradoxical, as it contains the risk of regression to “bad infinity”. Thus, “I see an object” obviously creates in me the image of the object; by implication, “someone” inside me sees the image of the perceived object and, consequently, ...

Machine learning (ML) has become a powerful tool for accelerating the development of carbon-based supercapacitors;
however, most published models assume that a single predictive framework can describe both conventional
porous carbons and hybrid carbon electrodes. Here, we test this assumption using a comprehensive
benchmark dataset and an extended literature-curated dataset enriched with synthesis- and electrolyte-related
descriptors. Three ML algorithms ...

Transformer-based Large Language Models (LLMs) rely on Key-Value (KV) cache to accelerate autoregressive decoding, but memory and compute requirements still grow with context length, limiting deployment on resource-constrained devices. Existing training-free KV cache compression methods mainly rely on attention-driven retention heuristics, which may under preserve structurally informative tokens under tight cache budgets, especially when such ...
