Understanding how seasonality shapes the dynamics of tuberculosis (TB) is essential in determining risks of transmission and drug resistance in (sub)tropical regions. We developed a relative fitness-based multidrug-resistant (MDR) TB model incorporated with seasonality and a probabilistic assessment model to assess infection risk in Taiwan regions. The model accurately captures the seasonal tra...

Data from linked birth and death certificates from the State of Oregon were used to determine the monthly distribution of deaths from sudden infant death syndrome (SIDS) for the years 1976 through 1984. The monthly number of SIDS deaths increased in winter and decreased in summer, when schools usually are not in session. Absences from kindergarten were determined from school records for the per...

Our paper addresses two questions on seasonal mortality: How do women and men differ with respect to seasonal fluctuations in mortality? How does seasonality in death change with age? The analysis is based on a sample of all Danes aged 50 and older on 1 April 1968 who were followed for 30 years. In contrast to previous studies we found remarkable differences between women and men in their seaso...

Seasonal changes in mood and behavior (seasonality) may be closely related to alcoholism. Some patients with alcoholism have a seasonal pattern to their alcohol misuse. They may be self-medicating an underlying seasonal affective disorder (SAD) with alcohol or manifesting a seasonal pattern to alcohol-induced depression. Both genetic and environmental factors play a role in the etiology and pat...

Methods: Cross-sections of 19 remnant pines exhibiting 190 fire scars were collected from a 1.2-km area. Tree-rings and fire scars were precisely dated and analysed for the purpose of characterizing past changes in fire and tree growth. Temporal variability in fire occurrence and seasonality was described for the preand post-European settlement periods. Seasonality of historic fires was determi...

X-12-ARIMA makes some assumptions about the relationship between trend and seasonality that are not always understood by users. In its simplest form, the observed series Yt can be considered a combination of three components: the trend-cycle Ct, the seasonal component St, and the irregular or random component It. Each of these components can enter the equation by multiplication or addition. Thu...

We investigated the long-term variations in primary production in Lake Taihu using Moderate Resolution Imaging Spectroradiometer (MODIS) data, based on the Vertically Generalized Production Model (VGPM). We firstly test the applicability of VGPM in Lake Taihu by comparing the results between the model-derived and the in situ results, and the results showed that a strong significant correlation ...

Present work focused on the seasonal variations in the physico-chemical parameters of the freshwater temple pondPrayagtirth at Trimbakeshwar in Nashik district during summer, monsoon and winter. A total 15 parameters were analysed and their seasonal variation is discussed. The correlation matrix of the various physico-chemical parameters are computed and analysed.
