ranibizumab in the past 10 months, his vision had reached 20/70, which produced significant difficulties for carrying out his daily activities. Fluorescein angiography was carried out, which revealed a superior extrafoveal leak point temporal to the papilla which caused serous detachment of the entire macula (Fig. 1). After the patient declined the photodynamic therapy option, a single photocoa...

This paper will give an introduction to the leak detection of vacuum systems. Various methods to detect leaks as well as the most widely used helium leak detectors and their different applications are presented. Practical examples in the context of accelerator vacuum systems will illustrate the topic.

KEY POINTS Ca leak from the sarcoplasmic reticulum through the ryanodine receptor (RyR) reduces the amplitude of the Ca transient and slows its rate of decay. In the presence of β-adrenergic stimulation, RyR-mediated Ca leak produces a biphasic decay of the Ca transient with a fast early phase and a slow late phase. Two forms of Ca leak have been studied, Ca-sensitising (induced by caffeine) an...

Background: Bile duct leak is an infrequent but serious disorder. The great majority occurs after hepatobiliary surgery. Early recognition and adequate multidisciplinary approach is the cornerstone for the optimal final outcomes. Traditionally, surgery has been the gold standard for the management of bile leak, but it is associated with significant morbidity and mortality. Biliary endoscopic pr...

results the mean age was 45.6 ± 13.1 (24 to 74 ) years. twenty-two were normal responders [considered as non-organic causes (37.3% of all patients)], 27 were classified as venous leakage, eight had arterial insufficiency and two were mixed type. maximum psv occurred before the fifth minute in 47 patients (92.2%). eight patients completed all phases of erection in the first 5 minutes. we defined...

PURPOSE To assess whether the presence and duration of air leaks after lobectomy are associated with an increased incidence of cardiopulmonary complications. METHODS Propensity score analysis was used on 726 patients undergoing pulmonary lobectomy from 1995 through 2004 to form three well-matched pairs of patients: patients with prolonged air leak (PAL) [> 7 days] and without air leak; patien...

Abstract Hydraulic model-based leak (burst) localisation in water distribution networks is a challenging problem due to limited number of hydraulic measurements, wide range properties, and model data uncertainties. In this study, prior assumptions are investigated improve the presence For example, $$\ell _2$$ ℓ</mml:mi...

Leak detection and localization in water distribution networks (WDNs) is of great significance for utilities. This paper proposes a leak method that requires hydraulic measurements structural information the network. It composed by an image encoding procedure recursive clustering/learning approach. Image carried out using Gramian angular field (GAF) on pressure to obtain images learning phase (...
