• New air-broadened IR absorption cross sections (850–1335 cm ?1 ) for HFC-32. Cover temperatures from 188 to 297 K and appropriate atmospheric pressures. More pressure temperature combinations than previous datasets. Difluoromethane (CH 2 F ; HFC-32), a hydrofluorocarbon (HFC) used as refrigerant in air conditioning heat pump systems, is currently being phased out under the terms of Montreal P...

Background The pursuit of high standards and continuous self-improvement are important aspects a professional attitude in medicine. However, when identity self-esteem dependent on flawless performance, healthy striving can become perfectionism. present study examines the influence perfectionism learning process basic instrument handling for minimally invasive surgery (MIS). Methods Thirty medic...

The application of diffusion theory and Monte Carlo lidar radiative transfer simulations presented in Part I this series study suggests that snow depth can be derived from the first-, second- third-order moments backscattering pathlength distribution. These methods are now applied to satellite ICESat-2 measurements over Arctic sea ice land surfaces Northern Hemisphere. Over ice, retrieved depth...

Ultrathin (UT) crystalline Si wafers, which are more flexible than conventional ones, can apply to curved surfaces, enabling a wide range of applications such as building‐integrated photovoltaics, vehicle‐integrated and wearable devices. Thinner wafers require effective light trapping; thus, surface texturing in microscale is common approach compensate for the reduced thickness by enhancing pat...

TO THE EDITOR: In a recent article, R. C. Davies et al. (2) presented the results of a study investigating the effect of eccentric exercise-induced muscle damage on the dynamics of pulmonary O2 uptake by near-infrared spectroscopy-based measurement of oxygenation in the vastus lateralis muscle. Although these results are of interest (1), we believe that certain points concerning the presentatio...

Even if on-board mm-wave/THz heterodyne receivers have been developed to measure greenhouse gases (GHGs) atmospheric profiles, rotational spectroscopy rests under-exploited for their monitoring unlike IR rovibrational spectroscopy. The present study deals with the ability of THz using long interaction path-lengths GHG laboratory investigations. High-resolution signatures non-polar molecules may...

a r t i c l e i n f o The key point in multivariate calibration is to build an accurate regression relationship between the predictors and responses. In this paper, we first use extreme learning machine (ELM) to build spectroscopy regression model. Then, we propose a combinational ELM (CELM) method in which the decision function is represented as a sum of a linear hidden-node output function (a...
