Melatonin modulates daily and seasonal rhythmic secretary pattern of endocrinological profiles in mithun bull

open access: yesIndian Journal of Animal Sciences, 2021
Present study was designed to evaluate the effect of slow release exogenous melatonin on endocrinological profiles in 24:00 hours in adult mithun bulls during different seasons (winter, spring, summer and autumn).

Examining Seasonality Based on Probabilistic Properties of Extreme Precipitation Timing in the Eastern United States

open access: yesAtmosphere, 2023
Global warming is likely to provoke extreme storms in the eastern United States (eUS), ultimately affecting the probabilistic distribution of the dates of daily maximum precipitation.

Evolutionary determinants of reproductive seasonality: A theoretical approach

open access: yesPeer Community Journal, 2023
Reproductive seasonality is a major adaptation to seasonal cycles and varies substantially among organisms. This variation, which was long thought to reflect a simple latitudinal gradient, remains poorly understood for many species, in part due to a ...

A Robust and Efficient Multi-Scale Seasonal-Trend Decomposition [PDF]

open access: yesIEEE ICASSP 2021, 2021
Many real-world time series exhibit multiple seasonality with different lengths. The removal of seasonal components is crucial in numerous applications of time series, including forecasting and anomaly detection. However, many seasonal-trend decomposition algorithms suffer from high computational cost and require a large amount of data when multiple ...

Frailty and Seasonality [PDF]

open access: yesThe Journal of nutrition, health and aging, 2020
Frailty in older adults is a complex condition in which only a minor external stressor may cause severe complications leading to death. In the context of the recent devastating bushfires in Australia and the worldwide COVID-19 pandemic, recognising and protecting those affected has magnified the impact and public health importance of frailty.

Suicide seasonality: complex demodulation as a novel approach in epidemiologic analysis. [PDF]

open access: yesPLoS ONE, 2011
Seasonality of suicides is well-known and nearly ubiquitous, but recent evidence showed inconsistent patterns of decreasing or increasing seasonality in different countries.

Increased health risk in subjects with high self-reported seasonality. [PDF]

open access: yesPLoS ONE, 2010
BACKGROUND: Seasonal variations in mood and behaviour, termed seasonality, are commonly reported in the general population. As a part of a large cross-sectional health survey in Hordaland, Norway, we investigated the relationship between seasonality ...

EEG-responses to mood induction interact with seasonality and age

open access: yesFrontiers in Psychiatry, 2022
The EEG is suggested as a potential diagnostic and prognostic biomarker for seasonal affective disorder (SAD). As a pre-clinical form of SAD, seasonality is operationalized as seasonal variation in mood, appetite, weight, sleep, energy, and socializing ...

On the Role of Seasonal Intercepts in Seasonal Cointegration [PDF]

open access: yesOxford Bulletin of Economics and Statistics, 1999
In the paper we consider the role of seasonal intercepts in seasonal cointegration analysis. For the nonseasonal unit root, such intercepts can generate a stochastic trend with a drift common to all observations. For the seasonal unit roots, however, we show that unrestricted seasonal intercepts generate trends that are different across the seasons ...
