The time-varying nature of the overreaction effect: evidence from the UK [PDF]
, 2011 Previous studies on the overreaction effect in the UK show that prior losers consistently outperform prior winners in the period 1975 to 1990. This paper extends current knowledge by assessing the above phenomenon in the UK market for the period 1987 to ...

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction Cognitive impairment and exercise intolerance are common in dialysis patients. Cerebral perfusion and oxygenation play a major role in both cognitive function and exercise execution; HD session per se aggravates cerebral ischemia in this population. This study aimed to compare cerebral oxygenation and perfusion at rest and in mild

Estimating the occurrence probability of Spring Thunderstorms using Markov chain, Case Study: Tabriz [PDF]
مخاطرات محیط طبیعی, 2018 Thunderstorms are one of the climatic phenomena that cause numerous damages in different parts of the world, due to the accompaniment with thunder, high winds, hail and heavy precipitation. In this study, the probability of thunderstorm days in Tabriz in

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing
FEBS Letters, EarlyView.Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Response of Ecohydrological Variables to Meteorological Drought under Climate Change
Remote Sensing, 2022 Drought is the most widespread climatic extreme that has negative impacts on ecohydrology. Studies have shown that drought can cause certain degrees of disturbances to different ecohydrological variables, but the duration and severity thresholds of ...

Return Periods of Hydrological Events [PDF]
Hydrology Research, 1977 A relation between return periods of hydrological events in annual maxima and partial duration series respectively is shown to be exactly fulfilled when the events take place according to a Poisson process. Furthermore it is shown that the relation can be used as a good approximation when dealing with more regular processes than the Poissonian. Finally

Computing return times or return periods with rare event algorithms [PDF]
Journal of Statistical Mechanics: Theory and Experiment, 2018 The average time between two occurrences of the same event, referred to as its return time (or return period), is a useful statistical concept for practical applications. For instance insurances or public agency may be interested by the return time of a 10m flood of the Seine river in Paris.

Time after time – circadian clocks through the lens of oscillator theory
FEBS Letters, EarlyView.Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

β‐TrCP overexpression enhances cisplatin sensitivity by depleting BRCA1
Molecular Oncology, EarlyView.Low levels of β‐TrCP (Panel A) allow the accumulation of BRCA1 and CtIP, which facilitate the repair of cisplatin‐induced DNA damage via homologous recombination (HR) and promote tumor cell survival. In contrast, high β‐TrCP expression (Panel B) leads to BRCA1 and CtIP degradation, impairing HR repair, resulting in persistent DNA damage and apoptosis ...

Hydrologic Drought Frequency Analysis in Karkhe Basin Based on Bivariate Statistical Analysis
علوم آب و خاک, 2018 In recent years, the joint distribution properties of drought including severity and duration have been widely evaluated using copula. Few studies, however, have worked on drought modeling based on stream flow, especially in semi-arid regions such as the
