There is a wide selection of flip-flops in the literature. Many contemporary microprocessors selectively use master-slave and pulsed-triggered flip-flops. Transmission gated flip-flop, are made up of two stages, one master and one slave Alternatively, pulse-triggered flip-flops reduce the two stages into one stage and are characterized by the soft edge property. The concepts discussed in the re...

We study flip graphs of (pseudo-)triangulations whose maximum vertex degree is bounded by a constant k. In particular, we consider (pseudo-)triangulations of sets of n points in convex position in the plane and prove that their flip graph is connected if and only if k > 6; the diameter of the flip graph is O(n). We also show that for general point sets flip graphs of minimum pseudo-triangulatio...

Pulse-triggered flip-flops are mainly used to improve speed of operation (pipeline speed), though flip-flop robustness and system timing closure are challenging in a wide range of supply voltages. Usually pulse-triggered flip-flops have specific structures and transistor sizes to optimize the system performance. The transistor size, topology, and threshold voltage of the flip-flop make the timi...

Background: Mycosis fungoides (MF) is the commonest variant of primary cutaneous T cell lymphoma with several clinicopathologic variants. Defective apoptotic mechanism may be important in the pathogenesis and progression of MF. c-FLIP protein is an important anti-apoptotic marker and chemotherapeutic resistant factor. This study aimed to evaluate the c-FLIP expression in MF and its role in the ...

Introduction: The knowledge of flip angle values is essential for accurate modeling in many quantitative MRI techniques. Recently, Actual Flip Angle Imaging (AFI) was proposed to account for multiple sources of flip angle variations such as transmit field inhomogeneity, B0 variations, slab profile, and excitation pulse effects [1]. AFI was successfully applied to yield system-independent T1 rel...
