Global change, like droughts, can destabilize the carbon sink function of peatlands, either directly or indirectly through changes in plant community composition. While the effects of drought and plant community composition on individual carbon (C) related processes are well understood, their effect on multiple C-related processes simultaneously-multifunctionality-is poorly known. We studied the effect of drought on four C-related processes (net and gross CO2 exchange, methane fluxes, and dissolved organic carbon content) in a plant removal experiment...

There is increasing interest in rituximab (RTX) as an alternative to cyclophosphamide for the treatment of interstitial lung diseases (ILDs) associated with systemic sclerosis (SSc). However, no report has addressed its efficacy in Saudi patients with SSc-ILD. To assess the efficacy of RTX treatment in Saudi patients with SSc-ILD, hospital records were reviewed between 2013 and 2016. Four female patients received at least 4 cycles of RTX (I cycle, consisting of two infusions of 1000 mg 2 weeks apart). Pulmonary function tests (PFTs) and chest high-resolution computed tomography (HRCT) were performed before and after treatment to assess the response...

For advanced atomic force microscopy (AFM) investigation of chemical surface modifications or very soft organic sample surfaces, the AFM probe tip needs to be operated in a liquid environment because any attractive or repulsive forces influenced by the measurement environment could obscure molecular forces. Due to fluid properties, the mechanical behavior of the AFM cantilever is influenced by the hydrodynamic drag force due to viscous friction with the liquid. This study provides a numerical model based on computational fluid dynamics (CFD) and investigates the hydrodynamic drag forces for different cantilever geometries and varying fluid conditions for Peakforce Tapping (PFT) in liquids...

High parental expressed emotion (EE), reflected by criticism or emotional over-involvement, has been related to poorer outcome in family-based treatment (FBT) for adolescent anorexia nervosa. This study assessed EE in 89 mothers and 64 fathers at baseline and end of treatment in a randomised trial comparing conjoint FBT to parent-focused FBT (PFT). Compared with conjoint FBT, PFT was associated with a decrease in maternal criticism, regardless of adolescent remission. Furthermore, an increase in maternal criticism was more likely to be observed in conjoint FBT (80%) than PFT (20%, p = 0...

INTRODUCTION: Congenital pulmonary airway malformation (CPAM) is a major indication of lobectomy in children. Early lobectomy had been proposed for the advantage of compensatory lung growth. Despite the increasing use of thoracoscopic lobectomy its effect on postoperative lung function was still not well established in the literature. This study was therefore performed to study the result of postoperative pulmonary function test (PFT) on a medium term basis. MATERIALS AND METHODS: All patients who underwent thoracoscopic lobectomy for CPAM between 2006 and 2010 were recruited into the study...

Y Wei, M Ibison, G Xia, J D A Smith, C P Welsch
This paper investigates numerically dual-grating dielectric laser-driven accelerators driven by a pulse-front-tilted (PFT) laser, which extends the interaction length and boosts the electrons' energy gain. The optical system necessary to generate PFT laser beams with an ultrashort pulse duration of 100 fs is also studied in detail. Through two-dimensional particle-in-cell simulations, we show that such a PFT laser effectively increases the energy gain by (91±25) % compared to that of a normally incident laser with a waist radius of 50 μm for a 100-period dual-grating structure...
