Covalent Organic Frameworks In article number 2205949, Dana Dina Medina, Ralf Thomas Weitz, Timothy Clark and co-workers describe the synthesis of covalent organic frameworks (COFs) based on a thiophene-extended benzotrithiophene (BTT) building block. Oriented thin films BTT COFs show room-temperature in-plane electrical conductivity up to 10−4 S m−1 trap-dominated charge transport via hopping ...
formed under the newly introduced Organ Transplant Law in February 1999. The number of heart transplants per year rose from 3 initially to 5, then to nearly 10. After the legislative amendments it rose to 30 and then 37 per year (Figure 1). Most of the early VADs used for BTT were extracorporeal devices, with implantable devices used mainly for clinical research or experimental trials of at-hom...
BACKGROUND The aim of this study was to evaluate the variability of clinician-performed Focused Assessment with Sonography for Trauma (FAST) examinations and its impact on abdominal computed tomography (AbCT) use in hemodynamically stable children with blunt torso trauma (BTT). The FAST is used with variable frequency in children with BTT. METHODS We performed a planned secondary analysis of ...
Microporous metal-organic frameworks are a class of materials being vigorously investigated for mobile hydrogen storage applications. For high-pressure storage at ambient temperatures, the M(3)[(M(4)Cl)(3)(BTT)(8)](2) (M-BTT; BTT(3-) = 1,3,5-benzenetristetrazolate) series of frameworks are of particular interest due to the high density of exposed metal cation sites on the pore surface. These si...
چکیده در این پایان نامه، روش کنترل مد لغزشی موجکی مبتنی بر تابع لغزشی متغیر با زمان با لایه مرزی تطبیقی ارائه می شود. سطح لغزشی متغیر با زمان، براساس یک پارامتر بازگشتی همه فرکانس های مدل نشده را فیلتر می کند. به منظور کاهش تاثیرات نامعینی های سیستم و فرکانس های مدل نشده، پهنای باند شکست فرکانس، پهنای لایه ی مرزی و پارامترهای حاصل از تقریب موجکی عصبی تعدیل خواهند شد. نوسانات شدید در سیگنال کنت...
Aims, Objectives and Background Blunt thoracic trauma (BTT) is a leading cause of emergency department (ED) trauma-related attendance. The STUMBL score prognostic model for BTT, derived validated in the United Kingdom; this study’s aim was to validate an Italian ED. Method Design This single-centre retrospective validation study conducted ED Cuneo hospital, north-western Italy. All patients wit...
BACKGROUND Left ventricular assist device (LVAD) and inotrope therapy serve as a bridge to transplant (BTT) or as destination therapy in patients who are not heart transplant candidates. End-stage heart failure patients often have impaired renal function, and renal outcomes after LVAD therapy versus inotrope therapy have not been evaluated. METHODS In this study, 169 patients with continuous ...
OBJECTIVE To analyze the efficacy of treating postviral olfactory loss with glucocorticoids, Ginkgo biloba, and mometasone furoate nasal spray. DESIGN Randomized trial. SETTING Academic research. PATIENTS Seventy-one patients who were diagnosed as having postviral olfactory loss. MAIN OUTCOME MEASURES All patients underwent olfactory function tests, including the butanol threshold test ...
BACKGROUND We recently reported that frailty is independently predictive of increased mortality in patients with advanced heart failure referred for heart transplantation (HTx). The aim of this study was to assess the impact of frailty on short-term outcomes after bridge-to-transplant ventricular assist device (BTT-VAD) implantation and/or HTx and to determine if frailty is reversible after the...
