Conventional repetitive control has proven to be an effective strategy to reject/track periodic signals with constant frequency; however, it shows poor performance in varying frequency applications. This paper proposes an active disturbance rejection methodology applied to a large class of uncertain flat systems for the tracking and rejection of periodic ...

In a previous work by Alvarez-Martinez et al. (2011), the authors pointed out some fallacies in the mainstream interpretation of the prion amyloid formation. It appeared necessary to propose an original hypothesis able to reconcile the in vitro data with the predictions of a mathematical model describing the problem. Here, ...

Staging of liver fibrosis is an integral part of the management of HCV. Liver biopsy is hampered by its invasiveness and possibility of sampling error. Current noninvasive methods are disadvantaged by their cost and complexity. In this study, we aimed at developing a noninvasive method for the staging of liver ...

Despite its invasiveness, liver biopsy is still considered the gold standard for the assessment of hepatic fibrosis. Non-invasive ultrasound-based techniques are increasingly employed to assess parenchymal stiffness and the progression of chronic diffuse liver diseases. Real-time elastography is a rapidly evolving technique that can reveal the elastic properties of tissues. ...

The differential stripping technique consists of a tape-stripping phase followed by a cyanoacrylate biopsy. This technique not only allows the quantification of drug retained in the stratum corneum (SC) and in the hair follicles but also differentiates transepidermal from transfollicular penetration. Our study aimed at both validating the differential stripping ...

Humans reject uneven divisions of resources, even at personal cost. This is observed in countless experiments using the ultimatum game, where a proposer offers to divide a resource with a responder who either accepts the division or rejects it (whereupon both earn zero). Researchers debate why humans evolved a psychology ...

Why have birds evolved the ability to reject eggs? Typically, foreign egg discrimination is interpreted as evidence that interspecific brood parasitism (IP) has selected for the host's ability to recognize and eliminate foreign eggs. Fewer studies explore the alternative hypothesis that rejection of interspecific eggs is a by-product of host ...

Recent studies report that the risk of colorectal cancer (CRC) among patients with ulcerative colitis (UC) may be lower than previously estimated. Although white-light endoscopy (WLE) with random biopsies is recommended for dysplasia detection in patients with UC, several studies reported increased detection of dysplasia by chromoendoscopy. To analyze the ...

Protein misfolding and concomitant aggregation towards amyloid formation is the underlying biochemical commonality among a wide range of human pathologies. Amyloid formation involves the conversion of proteins from their native monomeric states (intrinsically disordered or globular) to well-organized, fibrillar aggregates in a nucleation-dependent manner. Understanding the mechanism of aggregation is ...

This paper proposes a new wireless biopsy method where a magnetically actuated untethered soft capsule endoscope (MASCE) carries and releases a large number of thermo-sensitive, untethered micro-grippers (¿-grippers) at a desired location inside the stomach and retrieves them after they self-fold and grab tissue samples. We describe the working principles ...
