We study transport through a single channel T -stub geometry strongly coupled to a superconducting reservoir. In contrast to the standard stub geometry which has both transmission resonances and anti-resonances in the coherent limit, we find that due to the proximity effect, this geometry shows neither a T = 1 resonance (T is the transmission probability for electrons incident on the T -stub) n...

lymph node dissection is of prime importance for accurate staging of colorectal carcinomas. since a great number of small lymph nodes are missed in the traditional method, several fat clearing solutions have been introduced for easier detection of smaller lymph nodes. in this study we evaluated the efficacy of a new fat clearing solution so-called lymph node revealing solution (lnrs) in colecto...

background: the sentinel lymph node (sln) is defined as the first chain node in the lymphatic basin that receives primary lymphatic flow. if the sln is negative for metastatic disease, then other nodes are expected to be disease-free. sln techniques have been extensively applied in the staging and treatment of many tumors, including melanoma, breast and vulvar cancers. this study aims to evalua...

background: sentinel lymph node biopsy (slnb) has replaced axillary lymph node dissection (alnd) in early breast cancer patients as the first line surgical approach to axillary nodes. further dissection is performed only when sln is involved by tumor cells. however, in a significant proportion of patients, non-sentinel nodes are still not involved and axillary dissection has no additional thera...

A broadband microstrip bandpass filter (BPF) with compact size, sharp skirt and wide upperstopband performance is proposed using the triple-mode stub-loaded resonator. The resonator can generate one odd mode and two even modes in the desired passband. Due to the main path signal counteraction, two transmission zeros Tz1, Tz2 can be created near the passband edge to achieve sharp skirt. Two tran...

In this study, a new refractive index sensor based on a metal-insulator-metal waveguide coupled with a notched ring resonator and stub is designed. The finite element method is used to study the propagation characteristics of the sensor. According to the calculation results, the transmission spectrum exhibits a typical Fano resonance shape. The phenomenon of Fano resonance is caused by the coup...

This paper presents a new dual-mode stub-loaded resonator, which consists of a microstrip resonator with internal coupled lines and an open-circuited stub. Based on the oddand even-mode equivalent circuits, the resonant characteristics of the proposed microstrip resonator are investigated. It is found that the fundamental even-mode resonant frequency of the proposed resonator can be flexibly co...

A wideband planar inverted-F MIMO antenna with high isolation is proposed in this letter. The proposed MIMO antenna consists of two back-to-back planar inverted-F antennas and a forkshaped decoupling stub. The two planar inverted-F antennas are merged together with a shorting strip connected to the ground plane. In order to enhance the isolation, a fork-shaped decoupling stub connected to the g...

JavaScript is expected to be a programming language of even wider use, considering demands for more interactive web/mobile applications and deployment in server-side software. While reliability of JavaScript code will be of more importance, testing techniques for the language remain insufficient, compared to other languages. We propose a technique to automatically generate high-coverage unit te...
