In this paper, an original model-based scheme for leak location using pressure sensors in water distribution networks is introduced. The proposed approach is based on a new representation called the Leak Signature Space (LSS) that associates a specific signature to each leak location being minimally affected by leak magnitude. The LSS considers a linear model approximation of the relation betwe...

With the rapid development of a continuously growing selection of unnatural amino acids (UAAs), UAA insertion becomes increasingly popular for investigating proteins. However, it can prove problematic to ensure the homogeneity of the expressed proteins, when homogeneity is compromised by "leak expression". Here, we show that leak expression may be mediated by reinitiation and can result in unwa...

Bronchial fistulae in communication with atmospheric pressure can be identified by the presence of a squeaking sound heard over the chest wall during a Valsalva maneuver. Furthermore, these leak sounds can help identify the size, location, and communications of the bronchial fistulae. The size of the leak can be inferred by the pitch of the leak sound. Large leaks produce low pitched sounds, sm...

Background: Anastomotic leaks in colorectal surgery results in a high morbidity and mortality rate. Serum procalcitonin levels is known as a sensitive and specific marker of sepsis and could be use as a marker for early detection of a leak allowing early intervention. It may help a clinician decide to perform a CT scan even earlier especially when the diagnosis of a leak is uncertain. The aim o...

Systemic capillary leak syndrome is characterized by recurrent hypovolemic shock attributable to increased systemic capillary leakage. A 26-year-old woman was admitted because of recurrent episodes of hypovolemic shock. Hemoconcentration, hypoalbuminemia, and monoclonal gammopathy were observed. We diagnosed systemic capillary leak syndrome. Three years later, she again had an attack of systemi...

The calibrated-leak balloon catheter, used for the selective catheterization of intracranial arteries, originally incorporated a silicone microballoon at its tip [1]. Latex balloons have now proven superior in elasticity and tensile strength when compared with balloons made of silicone [2] . Consequently, most workers construct the calibrated-leak balloon catheter by gluing a leaking latex micr...

Privacy information is prone to be leaked by illegal software providers with various motivations. Privacy leak behavior has thus become an important research issue of cyber security. However, existing approaches can only qualitatively analyze privacy leak behavior of software applications. No quantitative approach, to the best of our knowledge, has been developed in the open literature. To fill...
