BACKGROUND The major long-term complication of laparoscopic adjustable gastric banding (LAGB) is dilatation of the gastric pouch, that is reported with a frequency ranging from 1 to 25%, and often requires removal of the band. In addition to the usual recommendations of bariatric surgery centers and dietetic advice to prevent this complication, over the last 4 years we introduced a technical mo...

Multi-band optical fiber transmission is generally proposed for capacity upgrades in transport networks. To comprehensively assess the potential of multi-band transmission, key metrics such as increase, energy consumption, and number required interfaces must be evaluated different scenarios. We consider progressive spectral exploitation, starting from C-band only up to C+L+S+U-band both transpa...

This paper investigates spectrum slicer placement problem under a allocation scheme that considers the splitting process to minimize blocking probability for elastic optical network with sparse slicers. Unlike conventional without slicers, slicers is able split band into several components by replicating original and filtering out an unwanted signal on each band. The largest L-shape fit algorit...

In this paper, we investigate the dynamically tunable plasmon-induced transparency (PIT) effects in parallel black phosphorus nanoribbons (BPNRs). The proposed structures consist of several BPNRs having different lengths one transverse period. periods all are set as $$P = 500 \, nm$$ . To our best knowledge, these have not been reported published papers. It is first time that simulates PIT by w...

recently many studies have been done on different issues of using multiple antennas at transmit and receive sides of a radar system in a mimo (multiple input multiple output) configuration. in addition, for the electronic warfare‟s purposes, the utilization of available signals of the environment to detect the targets has gained considerable attention in recent years. such passive radars use th...

many real world problems can be modelled as an optimization problem. evolutionary algorithms are used to solve these problems. ant colony algorithm is a class of evolutionary algorithms that have been inspired of some specific ants looking for food in the nature. these ants leave trail pheromone on the ground to mark good ways that can be followed by other members of the group. ant colony optim...

The present wireless applications demand a compact, multi-operated, and stable radiation pattern antenna with good gain impedance matching performance. To accomplish this requirement. In paper, we propose compact metamaterial structure loaded quad band antenna. structural specifications/layout of the consists circular ring monopole fed by microstrip line. ground part is rectangular split-ring r...

Laparoscopic adjustable gastric banding is a popular method in bariatric surgery. A silicone ring is adjusted in the gastric fundus to create a smaller proximal compartment [1]. Intragastric migration of a gastric band is a common complication that might require surgical treatment. A 36 year-old woman who underwent adjustable gastric band placement 7 years before was referred to our center due ...

A novel baseline estimation procedure building on previously published works is presented. •The core of the estimation is an iterative spectrum suppression consisting of a moving window minimum replacement (adapted from Friedrichs [1]).•Four, easily understandable, parameters control placement of the baseline relative to the noise band around the signal (adapted from Eilers [2]) and the flexibi...
