Changing snow water storage in natural snow reservoirs [PDF]

open access: yesHydrology and Earth System Sciences
This work introduces a novel snow metric, snow water storage (SwS), defined as the integrated area under the snow water equivalent (SWE) curve (units: length-time, e.g., m d).

Surface Wind Speed Changes and Their Potential Impact on Wind Energy Resources Across China During 1961–2021

open access: yesGeoHealth, 2023
Enabling the rational use of energy and the realization of the “dual carbon goals” across China will require systematic analysis of temporal and spatial changes in surface wind speed (SWS), determination of key factors influencing SWS, and quantification

ISO-SWS spectroscopy of NGC 1068 [PDF]

open access: yes, 2000
We present ISO-SWS spectroscopy of NGC 1068 for the wavelength range 2.4 to 45um, detecting a total of 36 emission lines. Most of the observed transitions are fine structure and recombination lines originating in the narrow line region.

Oscillatory Instabilities of Standing Waves in One-Dimensional Nonlinear Lattices

open access: yes, 2000
In one-dimensional anharmonic lattices, we construct nonlinear standing waves (SWs) reducing to harmonic SWs at small amplitude. For SWs with spatial periodicity incommensurate with the lattice period, a transition by breaking of analyticity versus wave ...

Experimental and numerical study of turbulent penetrative Rayleigh-Bénard flow of water near 4 °C in a box-shaped container

open access: yesCase Studies in Thermal Engineering
Understanding the reversal process of the large-scale circulation will facilitate system recognition of turbulent penetrative Rayleigh-Bénard convection.

Analysis of W-band traveling-wave tube based upon slotted sine waveguide slow wave structure

open access: yesAIP Advances, 2021
In this paper, a W-band traveling-wave tube (TWT) is proposed by combining the slotted sine waveguide (SSWG) slow-wave structure (SWS) with the cylindrical electron beam.

SW-AG [PDF]

open access: yesProceedings of the 4th International Workshop on Semantic Evaluations - SemEval '07, 2007
We present two systems that pick the ten most appropriate substitutes for a marked word in a test sentence. The first system scores candidates based on how frequently their local contexts match that of the marked word. The second system, an enhancement to the first, incorporates cosine similarity using unigram features.

Magnetic domain-wall motion by propagating spin waves

open access: yes, 2009
We found by micromagnetic simulations that the motion of a transverse wall (TW) type domain wall in magnetic thin-film nanostripes can be manipulated via interaction with spin waves (SWs) propagating through the TW.

Shift schedules and circadian preferences: the association with sleep and mood

open access: yesFrontiers in Public Health
ObjectWe explored the circadian preferences of non-shift workers (non-SWs) and various types of shift workers (SWs), and the associations of these preferences with sleep and mood.MethodsIn total, 4,561 SWs (2,419 women and 2,142 men aged 37.00 ± 9.80 ...

A clinician′s dilemma: Sturge-Weber syndrome ′without facial nevus′!!

open access: yesAnnals of Indian Academy of Neurology, 2013
Sturge-Weber syndrome (SWS) is a rare, sporadic neurocutaneous syndrome characterized by a classical triad of facial port wine nevus, ipsilateral leptomeningeal angiomatosis (LAM) and glaucoma. The incidence of SWS is 1/50,000 live births, although it is
