A set of modular 2-manifold surface components has been designed that allows the assembly of free-form geometrical sculptures representing single-sided or double-sided surfaces ranging from genus 2 to genus 22. The paper describes the interplay between parameters that define the overall symmetry of the whole structure and other parameters that define the geometry of the individual modular compo...

Compact selective bandpass filter, based on the Rhodes approximation, is proposed using the novel modified hairpin resonators realized on a double-sided microstrip. The equivalence is presented between the hairpin resonator realized on a singlesided microstrip and the modified hairpin resonator realized on a double-sided microstrip. The footprint area of the filter is reduced by 50% with the mu...

The aim of this paper is to introduce $(L,M)$-fuzzy closurestructure where $L$ and $M$ are strictly two-sided, commutativequantales. Firstly, we define $(L,M)$-fuzzy closure spaces and getsome relations between $(L,M)$-double fuzzy topological spaces and$(L,M)$-fuzzy closure spaces. Then, we introduce initial$(L,M)$-fuzzy closure structures and we prove that the category$(L,M)$-{bf FC} of $(L,M...

We compare single- and double-sided excitation methods of adiabatic surface plasmon polariton (SPP) wave superfocusing for scattering-type metallic near-field scanning optical microscopy (s-NSOM). Using the results of full 3D finite difference time domain analyses, the differences in field enhancement factors are explained and reveal the mode selectivity of a conical NSOM tip for adiabatic SPP ...

This article introduces chirp spread spectrum technology (CSS for short) and optimized location algorithm. Symmetric double-sided two way ranging technique (SDS– TWR for short) is applied to improve accuracy and range of measurement. Linear frequency modulation ranging technology utilizes protocols combining CSMA / CA and TDMA, and adjusts dynamically transmission rate and frame length accordin...

Two cases of asymptomatic double aortic arch with tetralogy of Fallot are reported. One presented with a non-dominant left arch and left-sided descending thoracic aorta and the other with a non-dominant left arch, a right-sided descending thoracic aorta and a patent ductus arteriosus. One-stage operation was performed and both patients were discharged free of symptoms and signs related to the d...

In this work, we developed a new ion exchange plating (IEP) method that is different to traditional electrochemical plating or electroless plating techniques. A variety of silver patterns were prepared by using the IEP technique as demonstrated in this work. The key factors to the definition and the conductive performance of silver patterns were systematically studied. Mechanisms of the formati...

Septation is one of the surgical choices for double-inlet left ventricle, yet postoperative hemodynamics have not been well defined. We studied ventricular volume characteristics in 10 patients with double-inlet left ventricle before and after septation. Preoperative end-diastolic volume (EDV) of the ventricle was 291±111% (±SD) of normal and ejection fraction (EF) was 0.59± 0.07. Postoperative...

OBJECTIVES Graft occlusion is a problem after superior vena cava (SVC) reconstruction for thoracic malignancy. Expanded polytetrafluoroethylene (ePTFE) is considered to be an optimal material for venous reconstruction. METHODS We reviewed the hospital records of 13 patients who underwent complete resection of thoracic malignancy invading the SVC, including SVC reconstruction with ePTFE grafts...
