In [1] a prospective current-mode ARC filter implementation based on a wave description principle has been introduced. This idea can be easily modified to obtain sampled-data SI filter structure, as shown in [2]. Similarly to the "conventional" digital wave filters, the analog implementation is based on the description of the passive LC prototype ladder structure branches using scattering matri...

A four port network adder-subtractor module, for surface plasmon polariton (SPP) waves based on a ring resonator filter is proposed. The functionality of module is achieved by the phase difference manipulation of guided SPPs through different arms connected to the ring resonator. The module is designed using the concepts of a basic two-port device proposed in this paper. It is shown that two po...

A fluid–structure interaction model in a port-Hamiltonian representation is derived for classical guitar. After discretization, we combine the laws of continuum mechanics solids and fluids within unified (pH) modelling approach by adapting equations through an appropriate coordinate transformation on second-order level. The high-dimensionality resulting system reduced order reduction. article f...

The Indonesian fertiliser industry is a significant contributor to the national economy. Given the need to distribute its products to customers on the 17,000 islands making up the Indonesian archipelago, capacity and availability of ports are major factors in managing fertiliser product lifecycles. Improving the management of material flow in ports results in more efficient loading and unloadin...

BACKGROUND To investigate the effects of postoperative radiotherapy (PORT) on the survival of patients with resected stage IIIA-N2 non-small cell lung cancer (NSCLC). METHODS A total of 3,334 patients with resected stage IIIA-N2 NSCLC in 2004 to 2013 were identified in the Surveillance, Epidemiology, and End Results database and stratified according to use of PORT. Propensity score-matching (...

Postoperative radiotherapy (PORT), especially using modern technology, for patients with stage IIIA-N2 non-small cell lung cancer (NSCLC) is controversial. We retrospectively investigated 112 patients with stage IIIA-N2 NSCLC who underwent complete resection of the lung tumor in our institution from 1986 through 2003. Among the 91 patients determined suitable candidates for PORT postoperatively...

BACKGROUND/AIMS Since the first successful laparoscopic cholecystectomy with the establishment of pneumoperitoneum in France by Mouret in 1987, it has become the golden standard for cholecystectomy. Generally techniques with four trocars have been used with surgeons but some of them prefer 3-trocar techniques. Our aim is to compare the clinical outcomes of three- and four-port techniques prospe...

Introduction: In conventional Laparoscopic Appendicectomy, three ports are used wherein both the subumbilical and supra-pubic port sites are hidden the by the natural camouflages and the only visible scar is the third port in the iliac fossa. The third port scar can be made invisible by using a needle port for trans-parietal appendicular traction. Materials and Methods: From January 2013 to May...

Introduction Single-port laparoscopic surgery has some advantages, including improved cosmetic outcomes and minimized parietal trauma. However, pure single-port laparoscopic rectal cancer surgery is challenging because of the difficulties in creating triangulation and applying the laparoscopic staplers with sufficient distal margins in the narrow pelvic cavity. Recently, a reduced-port robotic ...
