The (in)visibility of groomed ski runs [PDF]
i-Perception, 2019 I analyse the visibility of “groomed” ski runs under different lighting conditions. A model of human contrast sensitivity predicts that the spatial period of groomed snow may render it invisible in the shade or on overcast days. I confirm this prediction with visual demonstrations and make a suggestion to improve visibility.

Sensors, 2015 This study uses inertial sensors to measure ski jumper kinematics and joint dynamics, which was until now only a part of simulation studies. For subsequent calculation of dynamics in the joints, a link-segment model was developed. The model relies on the

Development of operational decision support tools for mechanized ski guiding using avalanche terrain modeling, GPS tracking, and machine learning [PDF]
Natural Hazards and Earth System SciencesSnow avalanches are the primary mountain hazard for mechanized skiing operations. Helicopter and snowcat ski guides are tasked with finding safe terrain to provide guests with enjoyable skiing in a fast-paced and highly dynamic and complex decision ...

Coefficient of Difficulty in Running a Sports Course in Alpine Skiing
Applied Sciences, 2023 In alpine ski disciplines, it is common for competitors to record incomplete runs. In some instances, up to 40% of competitors have failed to complete a course. Possible reasons include incorrect preparation of skiers (lack of adequate motor preparation)

IMPACT OF SKI RUNNING AND SKI ORIENTATION ON THE ENVIROMENT
Trakia Journal of Sciences, 2020 The purpose of this study is to demonstrate the existence of environmental problems in ski sports. They must not disturb its environmental sustainability and be realized under optimal conditions of the environment. The results obtained unequivocally reveal weaknesses in organizing and conducting winter sports events.

The Wadge Hierarchy of Deterministic Tree Languages
, 2008 We provide a complete description of the Wadge hierarchy for deterministically recognisable sets of infinite trees. In particular we give an elementary procedure to decide if one deterministic tree language is continuously reducible to another.

DESCRIPTION OF \u3ci\u3eHAKKA\u3c/i\u3e, A NEW GENUS OF JUMPING SPIDER (ARANEAE, SALTICIDAE) FROM HAWAII AND EAST ASIA [PDF]
, 2001 We describe a new genus for a jumping spider that was originally placed in the large genus Menemerus Simon 1868, from which the new genus is clearly different. They were later reclassified as Icius, then as Pseudicius, and still later as Salticus.

Parameters of the In-Run Position of Juniors’ Body at the Beginning of Take-Off
Physical Education Theory and Methodology, 2017 The objective is to determine the differences in the technique of the in-run position execution at the beginning of take-off by junior ski-jumpers of different qualification (sports training). Materials and methods. The participants in the study were 22

Alkyltriphenylphosphonium Binding to Cardiolipin Triggers Oncosis in Cancer Cells
Advanced Science, EarlyView.Alkyltriphenylphosphonium, exemplified by TPP+‐C14, preferentially accumulates in mitochondria and selectively binds to cardiolipin, a key phospholipid of the inner mitochondrial membrane, causing loss of mitochondrial membrane potential, severe cellular ATP depletion, and calcium imbalance.
