3D magnetic configuration of the Halpha filament and X-ray sigmoid in NOAA AR 8151 [PDF]

open access: yes, 2004
We investigate the structure and relationship of an H $\alpha$ filament and an X-ray sigmoid observed in active region NOAA 8151. We first examine the presence of such structures in the reconstructed 3D coronal magnetic field obtained from the non ...

Ultrasensitive response motifs: basic amplifiers in molecular signalling networks [PDF]

open access: yesOpen Biology, 2013
Multi-component signal transduction pathways and gene regulatory circuits underpin integrated cellular responses to perturbations. A recurring set of network motifs serve as the basic building blocks of these molecular signalling networks.

Elective Laparoscopic Sigmoidectomy with Preservation of the Superior Rectal Artery Prior to Endoscopic Decompression in Sigmoid Volvulus

open access: yesJournal of Coloproctology, 2021
Sigmoid volvulus is a frequent cause of intestinal obstruction. Its management has evolved with the use of laparoscopic surgery, achieving an elective sigmoid resection with anastomosis after a flexible endoscopic detorsion. A female patient was admitted

Laparoscopic peritoneal lavage. Our experience and review of the literature [PDF]

open access: yes, 2016
NTRODUCTION: Over the years various therapeutic techniques for diverticulitis have been developed. Laparoscopic peritoneal lavage (LPL) appears to be a safe and useful treatment, and it could be an effective alternative to colonic resection in emergency

Making Risk Minimization Tolerant to Label Noise [PDF]

open access: yes, 2015
In many applications, the training data, from which one needs to learn a classifier, is corrupted with label noise. Many standard algorithms such as SVM perform poorly in presence of label noise.

Analysis of Noise in Complex-Valued Binary and Bipolar Sigmoid Compressive Sensing

open access: yesTelfor Journal, 2019
Binary compressive sensing (CS) is a relatively new idea in the theory of sparse signal reconstruction. Under this framework, the signal is reconstructed based on the sign of the available measurements.

Russell Body Lesions of the Colon: Case Report and Literature Review

open access: yesThe Korean Journal of Gastroenterology, 2021
Russell bodies (RB) are rare manifestations within the lower gastrointestinal tract. To date, there are only three other reported cases of RB lesions of the colon; two were polyps, and the third was a case of a multifocal RB lesion of the ...

Threshold of potential concern: an early way to identify the ecosystem structural thresholds in a grazing gradient [PDF]

open access: yesEnvironmental Resources Research, 2018
Identification of ecosystem thresholds is a way to predict future changes and taking the bestmanagement practices in restoration processes. Thresholds are an integral part of nonlinearresponses of ecosystems to disturbances such as climate change or ...
