ランダムな擾乱媒質と指向誤差を伴う光宇宙通信における光波伝搬

, 2003
This study is devoted to lightwave propagation in the presence of random pointing jitter and atmospheric turbulence. The intrinsic narrow beam/high gain nature of free-space laser communications produces several extremely valuable advantages when ...

Vernalization regulatory network identifies potential novel functions for genes in the HvVRN2 locus

New Phytologist, Volume 250, Issue 6, Page 4036-4053, June 2026.
Summary Flowering is controlled by environmental and genetic factors. Vernalization requirement in barley (Hordeum vulgare L.) is determined by the allele in HvVRN1 and the presence of locus HvVRN2, which consists of two zinc‐finger and CONSTANS‐like domains (ZCCT) genes: HvVRN2a and HvVRN2b.

Morphology‐Mechanics Links of the Free Achilles Tendon Revealed by Three‐Dimensional Magnetic Resonance Imaging and Ultrasound Texture Analysis

Scandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 6, June 2026.
ABSTRACT This study aimed to elucidate the relationship between morphological and mechanical characteristics of the free Achilles tendon (ATFree) in vivo. The morphological features were characterized in terms of overall dimensions (length and cross‐sectional area) and internal fascicular organization (longitudinal alignment and transverse structure ...
