Mitral valve repair is currently considered the standard treatment for mitral regurgitation. Posterior leaflet prolapse has been treated by quadrangular resection and ring annuloplasty for many years. Although it is a classic and reproducible method, this technique may predispose to systolic anterior motion (SAM) of the anterior leaflet of the mitral valve. The incidence of SAM has been reporte...

On operative inspection, the lesion was between the anterior mitral leaflet and primary chordae (Figure 2). A mitral valve repair (28 mm ring annuloplasty, triangular resection of the anterior leaflet and n...

We consider an electronic model for realizing the spin Bose-metal SBM phase on a two-leg triangular strip—a spin liquid phase found by Sheng et al. Phys. Rev. B 79, 205112 2009 in a spin-1/2 model with ring exchanges. The SBM can be viewed as a “C1S2” Mott insulator of electrons where the overall charge transporting mode is gapped out. We start from a two-band “C2S2” metal and consider extended...

In this paper, we present a study of tuneable equilateral triangular shaped spilt ring resonator (ETSRR). In this ETSRR we rotate the inner and outer rings by varying the position of the splits in rings. For this we used radio frequency microelectromechanical system (RF MEMS) switches. By making MEMS switches ON/OFF, the positions of splits in the rings were varied which can be considered as ro...

The character of the principal series of representations of SL(n,R) is evaluated by using Gel’fand and Naimark’s definition of character. This representation is realized in the space of functions defined on the right coset space of SL(n,R) with respect to the subgroup of real triangular matrices. This form of the representations considerably simplifies the problem of determination of the integr...

We propose a novel quantum spin liquid state that can explain many of the intriguing experimental properties of the low-temperature phase of the organic spin liquid candidate materials κ-(BEDT-TTF)2Cu2(CN)3 and EtMe3Sb[Pd(dmit)2]2. This state of paired fermionic spinons preserves all symmetries of the system, and it has a gapless excitation spectrum with quadratic bands that touch at momentum k...

Abstract In this review, we engineer a high-performing nanosensor mechanic based on SPPs, which consists of metal-insulator-metal waveguide coupled with two triangular plates in double-internal-pile ring cavity (DISRC). The feasibility establishing the sensor SPPs is analyzed theoretically, and parameters DISRC are simulated by finite element method. best sensitivity proposed system 2640 nm/RIU...

in this paper, we introduce the new notion of n-f-clean rings as a generalization of f-clean rings. next, we investigate some properties of such rings. we prove that mn(r) is n-f-clean for any n-f-clean ring r. we also, get a condition under which the denitions of n-cleanness and n-f-cleanness are equivalent.

a topoframe, denoted by $l_{ tau}$,  is a pair $(l, tau)$ consisting of a frame $l$ and a subframe $ tau $ all of whose elements are complementary elements in$l$. in this paper, we define and study the notions of a$tau $-real-continuous function on a frame $l$ and the set of realcontinuous functions $mathcal{r}l_tau $ as an $f$-ring.we show that $mathcal{r}l_{ tau}$is actually a generalization ...
