Sublimation of ice crystals in cirrus clouds is often invoked as a moistening mechanism for the free troposphere, particularly in the tropics. An alternative mechanism is investigated here: "pumping" of water vapor into the cloudy atmospheric olumn from surrounding regions by diabatic transports resulting from the local radiative effects of the cloud. The effectiveness of this mechanism is comp...

Owing to their high reliability, simplicity of manufacture, passive operation, and effective heat transport, flat heat pipes and vapor chambers are used extensively in the thermal management of electronic devices. The need for concurrent size, weight, and performance improvements in high-performance electronics systems, without resort to active liquid-cooling strategies, demands passive heat sp...

Low-pressure sputtering and ionized vapor deposition processes create atomic fluxes with kinetic energies in the 1.0–20 eV (and above) range. The impact energy of these hyperthermal atoms significantly effects the surface morphology and structure of vapor deposited films. Recent molecular dynamics simulations of metal atom interactions with a metal surface have established the energy and angula...

Split cuts are among the most important and well-understood cuts for general mixed-integer programs. In this paper we consider some recent generalizations of split cuts and compare their relative strength. More precisely, we compare the elementary closures of split, cross, crooked cross and general multi-branch split cuts as well as cuts obtained from multi-row and basic relaxations. We present...

In this paper we propose a set of novel tunable optical power splitters based on active microring resonators. They work by operating ring resonators in the transient zone between full resonance and off-resonance states for a specific wavelength. We can achieve different split ratios by either varying the bias voltage, or by selectively enabling a given resonator with a specific split ratio amon...

We study a non-typical excitation mode of the copper bromide active medium using kinetic model. The is pumped by pulse train and laser generation obtained in subsequent single pulse. Such allows one to obtain with extended duration increase pause after train. relaxation processes during are studied order explain such effect. It shown that this operation can also be used superradiance amplificat...

Few satisfactory therapeutic agents are available for the control of Influenza virus, largely because of the continual emergence of drug-resistant mutants. Some essential oils (EOs) have demonstrated effective antimicrobial and antiviral properties in experimental conditions, but most of these studies tested the liquid oil phases, which are generally less practical and are potentially toxic for...

A semiclassical approach based on the WKB–Maslov method is developed for kinetic ionization equation in dense plasma with approximations characteristic of metal vapor active media excited by a contracted discharge. We develop technique constructing leading term asymptotics Cauchy problem solution under supposition weak diffusion. In terms developed, local cubic nonlinear original considered non...

[1] The direct effect of condensate evaporation on atmospheric water vapor and its isotopic composition is assessed in a climate model. The model contains two parallel hydrologic cycles, an active one which influences the model physics and dynamics and a passive one which does not. Two model simulations are performed, one in which passive cloud and precipitation can evaporate and one in which t...
