An Energy Budget for the Olfactory Glomerulus [PDF]

The Journal of Neuroscience, 2007
Energy demands are becoming recognized as an important constraint on neural signaling. The olfactory glomerulus provides a well defined system for analyzing this question. Odor stimulation elicits high-energy demands in olfactory glomeruli where olfactory axons converge onto dendrites of olfactory bulb neurons.

Appraising the brain's energy budget [PDF]

Proceedings of the National Academy of Sciences, 2002
In the average adult human, the brain represents about 2% of the body weight. Remarkably, despite its relatively small size, the brain accounts for about 20% of the oxygen and, hence, calories consumed by the body (1). This high rate of metabolism is remarkably constant despite widely varying mental and motoric activity (2).

How to improve our understanding of solar wind-magnetosphere interactions on the basis of the statistical evaluation of the energy budget in the magnetosheath?

Frontiers in Astronomy and Space Sciences, 2023
Solar wind (SW) quantities, referred to as coupling parameters (CPs), are often used in statistical studies devoted to the analysis of SW–magnetosphere–ionosphere couplings.

Study the effect of the host on the survival and energy budget of Habrobracon hebetor (Hym., Braconidae) [PDF]

نامه انجمن حشره‌شناسی ایران
Using of biological control agents, especially parasitoids, within the Integrated Pest Management (IPM) programs is increasingly expanding. Several factors can influence the effectiveness of parasitoids, the most important of which is the type and ...

Examining the Regional Co‐Variability of the Atmospheric Water and Energy Imbalances in Different Model Configurations—Linking Clouds and Circulation

Journal of Advances in Modeling Earth Systems, 2022
Clouds are a key player in the global climate system, affecting the atmospheric water and energy budgets, and they are strongly coupled to the large‐scale atmospheric circulation.

Energy budget increases reduce mean streamflow more than snow–rain transitions: using integrated modeling to isolate climate change impacts on Rocky Mountain hydrology

Environmental Research Letters, 2016
In snow-dominated mountain regions, a warming climate is expected to alter two drivers of hydrology: (1) decrease the fraction of precipitation falling as snow; and (2) increase surface energy available to drive evapotranspiration.

Influence of Propulsion Type on the Stratified Near Wake of an Axisymmetric Self-Propelled Body

Journal of Marine Science and Engineering, 2018
To better understand the influence of swirl on the thermally-stratified near wake of a self-propelled axisymmetric vehicle, three propulsor schemes were considered: a single propeller, contra-rotating propellers (CRP), and a zero-swirl, uniform-velocity ...

Camera‐trap data do not indicate scaling of diel activity and cathemerality with body mass in an East African mammal assemblage

Ecology and Evolution, 2021
Diel activity patterns of animal species reflect constraints imposed by morphological, physiological, and behavioral trade‐offs, but these trade‐offs are rarely quantified for multispecies assemblages. Based on a systematic year‐long camera‐trap study in

Assessing the impact of forest structure disturbances on the arboreal movement and energetics of orangutans—An agent-based modeling approach

Frontiers in Ecology and Evolution, 2022
Agent-based models have been developed and widely employed to assess the impact of disturbances or conservation management on animal habitat use, population development, and viability.

Impacts of Irrigation on the Heat Fluxes and Near-Surface Temperature in an Inland Irrigation Area of Northern China

Energies, 2014
Irrigated agriculture has the potential to alter regional to global climate significantly. We investigate how irrigation will affect regional climate in the future in an inland irrigation area of northern China, focusing on its effects on heat fluxes and
