Mid-Holocene expansion of the Indian Ocean warm pool documented in coral Sr/Ca records from Kenya

open access: yesScientific Reports, 2023
Proxy reconstructions suggest that mid-Holocene East African temperatures were warmer than today between 8 and 5 ka BP, but climate models cannot replicate this warming. Precessional forcing caused a shift of maximum insolation from boreal spring to fall

Exponential smoothing for intermittent demand with demand basis updated more frequently than seasonality factors

open access: yesGestão & Produção, 2019
This study aims to present an alternative technique of exponential smoothing to estimate the demand for items with intermittent and seasonal demand. The usual technique would aggregate demand periods (months in quarters, for instance) to calculate a ...

Forecasting with Multiple Seasonality [PDF]

open access: yesarXiv, 2020
An emerging number of modern applications involve forecasting time series data that exhibit both short-time dynamics and long-time seasonality. Specifically, time series with multiple seasonality is a difficult task with comparatively fewer discussions.

Harnessing Outer Space for Improved Electrocaloric Cooling

open access: yesAdvanced Functional Materials, EarlyView.
A novel radiative heat sink/source‐integrated electrocaloric (R‐iEC) system combines the electrocaloric (EC) effect with a thermally conductive radiative cooler (TCRC) to address heat dissipation limitations in EC devices. Utilizing outer space as a heat sink, the system achieves up to 240 W m−2 of heat dissipation performance, making it highly ...

Seasonality of coronaviruses and other respiratory viruses in Canada: Implications for COVID-19

open access: yesCanada Communicable Disease Report, 2021
Background: Like endemic coronaviruses, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is believed to have emerged in humans from a zoonotic source and may ultimately develop a seasonal pattern.

Seasonality, mediation and comparison (SMAC) methods to identify influences on lung function decline

open access: yesMethodsX, 2021
This study develops a comprehensive method to assess seasonal influences on a longitudinal marker and compare estimates between cohorts. The method extends existing approaches by (i) combining a sine-cosine model of seasonality with a specialized ...
