High frequency of moraine-dammed lake outburst floods driven by global warming [PDF]

Nature Communications
Glacial lake outburst floods (GLOFs) represent a major hazard in mountain regions, yet considerable uncertainty persists regarding whether their frequency has increased in recent decades and to what extent this trend is linked to climate change. Here, we

A Quantifiable Risk Factor for ACL Injury: Applied Mathematics to Model the Posterolateral Tibial Plateau Surface Geometry [PDF]

Orthopaedic Journal of Sports Medicine, 2021
Background: The mechanism for traumatic ruptures of the native anterior cruciate ligament (ACL) is frequently a noncontact injury involving a valgus moment with internal rotation of the tibia. The abnormal rotation and translation of the lateral femoral condyle posteroinferiorly relative to the lateral tibial plateau is thought to be related to the ...

Developing a finite difference hybrid method for solving second order initial-value problems for the Volterra type integro-differential equations [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2020
It is well known that the study of many processes of the natural sciences can be reduced to solving Volterra integrodifferential equations. Recent studies on certain problems of the environment such as the HIV virus, bird flu virus, and diseases ...

Mathematical model of the spread of COVID-19 in Plateau State, Nigeria

Journal of the Egyptian Mathematical Society, 2022
AbstractIn this research, a mathematical model consisting of non-pharmaceutical control measures is formulated. The developed model helps to examine the transmission of COVID-19 infection in Plateau State, Nigeria, using face masks$$c_{f}$$cfand social distancing$$c_{d}$$cdas control measures.

Simulating the current and future northern limit of permafrost on the Qinghai–Tibet Plateau [PDF]

The Cryosphere, 2022
Permafrost has been warming and thawing globally, with subsequent effects on the climate, hydrology, and the ecosystem. However, the permafrost thermal state variation in the northern lower limit of the permafrost zone (Xidatan) on the Qinghai–Tibet ...
