Practical Day‐Ahead Gas Generator Dispatch Optimisation for Enhancing the Reserved Capacity

IET Smart Energy Systems, EarlyView.
Practical day‐ahead gas generator dispatch optimisation model is proposed to enhance the system reserved capacity. ABSTRACT In order to reduce carbon dioxide emissions, traditional coal‐fired power generation has been strictly limited in China recently, which has led to the problem of reserved capacity shortage. As one of the critical east provinces of

Effect of the microbiome on pathogen susceptibility across four Drosophilidae species

Insect Science, EarlyView.
Four Drosophilidae species were used to investigate how variation in the host microbiome influences susceptibility to infection. Microbial composition and abundance differed among species and treatments. The effects of microbiome manipulation on host survival were both species‐ and pathogen‐specific.

Cooling down Lévy flights [PDF]

Journal of Physics A: Mathematical and Theoretical, 2007
Let L(t) be a Levy flights process with a stability index α\in(0,2), and U be an external multi-well potential. A jump-diffusion Z satisfying a stochastic differential equation dZ(t)=-U'(Z(t-))dt+σ(t)dL(t) describes an evolution of a Levy particle of an `instant temperature' σ(t) in an external force field.

Dilemmas of Civilian Participation in Military Deterrence and Defence: Legal and Ethical Dimensions

Global Policy, EarlyView.
ABSTRACT How can civilians participate in deterrence and defence in ways that do not jeopardize their immunity from deliberate attack? The principle of civilian immunity from deliberate attack in war is a core element of contemporary international humanitarian law (IHL). Uniformed combatants and others who take up arms pose a threat may be liable to be

Exploring the interplay between small and large scales movements in a neotropical small mammal

Movement Ecology
We record and analyze the movement patterns of the marsupial Didelphis aurita at different temporal scales. Animals trajectories are collected at a daily scale by using spool-and-line techniques and, with the help of radio-tracking devices, animals ...
