Although background noise cancellation for speech or electrocardiographic recording is well established, however when the background noise contains vocal noises and the main signal is a breath sound, the problem becomes challenging as the signal and noise are no longer uncorrelated. In this paper, a technique for detecting the vocal noise within a breath sound and then removing it without hampe...

A broadband microwave spectrometer has been constructed to determine the complex conductivity of thin metal films at frequencies from 45 MHz to 20 GHz working in the temperature range from 0.45 K to 2 K (in a (3)He cryostat). The setup follows the Corbino approach: a vector network analyzer measures the complex reflection coefficient of a microwave signal hitting the sample as termination of a ...

SUMMARY Increasingly, food companies play an important role in stemming the rising burden of nutrition-related chronic diseases. Concrete actions taken by these companies include global public commitments to address food reformulation, consumer information, responsible marketing, promotion of healthy lifestyles, and public-private partnerships. These actions are reviewed together with eleven sp...

Data from a Fortune 500 retailer suggest that managers tell strategically ambiguous, interwoven narratives about how an organization changes and how it remains the same, thereby attempting to both unfreeze and freeze the existing meanings employees attribute to the organization. Employees embellish these narratives to make sense of and narrate responses to change (resisting, championing, and ac...

Reporting of observational studies is often inadequate, hampering the assessment of their strengths and weaknesses and, consequently, the generalization of study results. The initiative named Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) developed a checklist of 22 items, the STROBE Statement, with recommendations about what should be included in a more accurate ...

In markets where transactions are governed by contractual incompleteness, revealed intentions to evade taxes may affect market performance. We experimentally examine the impact of tax evasion attempts on the performance of credence goods markets, where contractual incompleteness results from asymmetric information on the welfare maximizing quality of the good. We find that tax evasion attempts ...

Leasing is a very effective way to improve the performance of distributed algorithms without hampering their fault-tolerance. The notion of lease has traditionally been defined using a global notion of real time and was hence strongly tied to synchronous system models. This paper introduces a notion of lease object devised for an asynchronous system model. We give precise properties of our leas...

Thrombotic Thrombocytopenic Purpura-Hemolytic Uremic Syndrome (TTP-HUS) is a rare occurrence in pregnancy. It is similar in its clinical profile to other more common pregnancy related conditions like preeclampsia, eclampsia, and Hemolysis, Elevated Liver Enzymes, Low Platelets (HELLP) syndrome. This makes diagnosis a challenge thus hampering maternal and fetal outcome if the disease is not diag...

Sensors networks are the backbone of large sensing infrastructures such as Smart Cities or Smart Buildings. Classical approaches suffer from several limitations hampering developers’ work (e.g., lack of sensor sharing, lack of dynamicity in data collection policies, need to dig inside big data sets, absence of reuse between implementation platforms). This paper presents a tooled approach that t...
