Background: Frozen section is a standard of care procedure during thoracic surgery when an immediate diagnosis is needed. An alternative procedure is intraoperative cytology. Video-assisted thoracic surgery is currently widely used for thoracic surgical procedures. The aim of this study was to assess intraoperative cytology together with frozen section for accuracy, turnaround time, and total resp

Supercritical n-decane is applied in the regenerative cooling system of scramjet engines while scramjets are always in various irregular movements. With the desire to explore heat transfer performance of supercritical n-decane under actual flight conditions, numerical simulations and analysis of different states during the accelerated flight process are carried out under three different heat fluxe

A critical edition of the correspondence of the Swedish consul in Marseille, François Philippe Fölsch, this book takes a fresh look at trade and geopolitics in the eighteenth-century Mediterranean, the mechanisms used to combat the plague, and revolutionary events in Marseille.

Background: Bariatric surgery is a standard treatment for severe obesity, but little is known about patients’ perceptions about the long-term impact of such surgery. Objective: The aim of this study was to explore patients’ experiences of living with a bariatric procedure for more than a decade. Setting: University hospital. Methods: At the 10-year follow-up after undergoing Roux-en-Y gastric bypa

Objective: To examine the prevalence of sleep disturbances 10 years after Wenchuan earthquake, and to explore whether comorbid post-traumatic stress disorder (PTSD) and depressive symptoms could predict sleep disturbances and whether such effects were modified by gender. Methods: Participants were 1357 adolescents in the Wenchuan Earthquake Adolescent Health Cohort Study (WEAHC). 799 of the partic

BACKGROUND: Preoperative radiological assessment of meningioma characteristics is of value for pre- and post-operative patient management, counselling, and surgical approach.PURPOSE: To investigate whether tensor-valued diffusion MRI can add to the preoperative prediction of meningioma consistency, grade and type.MATERIALS AND METHODS: 30 patients with intracranial meningiomas (22 WHO grade I, 8 W

The decomposition of nonlinear chirp modes is a challenging task, typically requiring prior knowledge of the number of modes a signal contains. In this work, we present a greedy nonlinear chirp mode estimation (NCME) technique that forms the used decomposition basis from the signal itself, using an arctangent demodulation technique. The resulting decomposition is formed by considering the residual

The orthoceratite limestone of the Ordovician epicontinental sea of Baltoscandia is one of the oldest Phanerozoic examples of pelagic marine red beds (MRBs). Being enriched in authigenic haematite, MRBs are considered to be sensitive palaeoceanographic redox indicators. In this paper, the origin of the reddening of the Ordovician MRBs and its timing and redox conditions were addressed at two secti

BackgroundOur aim was to introduce damaged red blood cells (RBCs) as a tool for haemodynamic provocation in rats, hypothesised to cause decreased cerebral blood flow (CBF) and prolonged water capillary transfer time (CTT), and to investigate whether expected changes in CBF could be observed and if haemodynamic alterations were reflected by the CTT metric.MethodsDamaged RBCs exhibiting a mildly red

Cycling of water quality constituents in lakes is affected by thermal stratification and homo-thermal conditions and other factors such as oligotrophication, eutrophication, and microbial activities. In addition, hydrological variability can cause greater differences in water residence time and cycling of constituents in man-made lakes (reservoirs) than in natural lakes. Thus, investigations are n
