Stability of the proton-to-electron mass ratio

open access: yes, 2008
We report a limit on the fractional temporal variation of the proton-to-electron mass ratio as, obtained by comparing the frequency of a rovibrational transition in SF6 with the fundamental hyperfine transition in Cs.

Edge states of periodically kicked quantum rotors

open access: yes, 2015
We present a quantum localization phenomenon that exists in periodically kicked 3D rotors, but is absent in the commonly studied 2D ones: edge localization. We show that under the condition of a fractional quantum resonance there are states of the kicked

Efficacy of Fractional Versus Fully Ablative CO2 Laser for Distolateral Onychomycosis: Experience With 20 Patients

open access: yesDermatology Practical & Conceptual
Introduction: Oral antifungals are the treatment choice for onychomycosis, and topical therapies are favored in cases of limited nail involvement. Recently, carbon dioxide (CO2) laser treatment has emerged as an option to enhance the effectiveness of ...

Thrombospondin-3 augments injury-induced cardiomyopathy by intracellular integrin inhibition and sarcolemmal instability. [PDF]

open access: yes, 2019
Thrombospondins (Thbs) are a family of five secreted matricellular glycoproteins in vertebrates that broadly affect cell-matrix interaction. While Thbs4 is known to protect striated muscle from disease by enhancing sarcolemmal stability through increased

From Collagen Stimulation to Skin Regeneration: The Action of Fractional CO2 Laser and Insulin in Atrophic Acne Scars [PDF]

open access: yesInternational Journal of Medical Arts
Background: Post-acne scars, which typically do not go away with time, are a persistent and frequently upsetting consequence of acne. These scars can become more noticeable as the skin ages.

Doppler-free resolution near-infrared spectroscopy at 1.28~$\mu$m with the noise-immune cavity-enhanced optical heterodyne molecular spectroscopy method

open access: yes, 2017
We report on the Doppler-free saturation spectroscopy of the nitrous oxide (N$_2$O) overtone transition at 1.28~$\mu$m. This measurement is performed by the noise-immune cavity-enhanced optical heterodyne molecular spectroscopy (NICE-OHMS) technique ...

Fractional Ablative CO2 Laser Followed by Topical Application of Sodium Stibogluconate for Treatment of Active Cutaneous Leishmaniasis: A Randomized Controlled Trial

open access: yesActa Dermato-Venereologica, 2018
Conventional treatment of cutaneous leishmaniasis often leaves permanent scars with frequent psychosocial sequelae. The aim of this study was to compare the efficacy, safety, associated pain and final cosmetic outcome of fractional carbon dioxide (CO2 ...
