"Time is tissue"-A minireview on the importance of donor nephrectomy, donor hepatectomy, and implantation times in kidney and liver transplantation KU Leuven
Donor organs are exposed to sequential temperature changes during the transplantation process. The role of donor warm ischemia and cold ischemia times on post-transplant outcomes has been extensively studied. Much less attention has been paid to the transient ischemia occurring during donor organ removal and implantation. Recently, it has become clear that prolonged donor nephrectomy and implantation time are independently associated with ...
A Global Look at Time: A 24-Country Study of the Equivalence of the Zimbardo Time Perspective Inventory KU Leuven
© The Author(s) 2014. In this article, we assess the structural equivalence of the Zimbardo Time Perspective Inventory (ZTPI) across 26 samples from 24 countries (N = 12,200). The ZTPI is proven to be a valid and reliable index of individual differences in time perspective across five temporal categories: Past Negative, Past Positive, Present Fatalistic, Present Hedonistic, and Future. We obtained evidence for invariance of 36 items (out of 56) ...
Modelling embryo-endometrial crosstalk to reduce time to pregnancy (in times of health and pandemic) Vrije Universiteit Brussel
Embryo implantation is a bottleneck for pregnancy in many couples with a desire to conceive. Because of obvious ethical concerns regarding the use of human embryos for research and the unethical study of pregnancy in vivo, scientific advancement in the field is limited. The need to better understand the crosstalk between the embryo and the endometrium is crucial for IVF patients’ management. In particular, the latest SARS-CoV-2 pandemic and the ...

Path integral approach to the pricing of timer options with the Duru-Kleinert time transformation University of Antwerp
In this paper, a time substitution as used by Duru and Kleinert in their treatment of the hydrogen atom with path integrals is performed to price timer options under stochastic volatility models. We present general pricing formulas for both the perpetual timer call options and the finite time-horizon timer call options. These general results allow us to find closed-form pricing formulas for both the perpetual and the finite time-horizon timer ...
