An improved and facile preparation of 3,7-dinitro-1,3,5,7-tetraazabicyclo [3,3,1] nonane (DPT) has been developed starting from urea. In the procedure DPT was synthesized via N,N’-dinitrourea (DNU) as intermediate and various operating parameters such as temperature, pH and molar ratio of reagents have been optimized to give maximum yield of the desired product. The low cost method is concise, ...

The prevention and treatment of type-2 diabetes mellitus (T2DM) and diabetic nephropathy (DN), which are disorders with high incidence rates, is of primary importance. In this study, we analyzed the effect of 1,25-(OH)2D3 and lipopolysaccharide (LPS) in combination with interleukin (IL)-15 on the inflammatory immune response and expression of vitamin D receptor (VDR) in mononuclear cells of T2D...

As we enter the deep submicron era, the steadily shrinking feature sizes make charge sharing much easier among physically adjacent nodes in integrated circuits, which ultimately results in DNU (Double Nodes Upset). In this paper, we propose a 16-transistor memory cell. Hspice simulation shows this cell maintains its original logic status under SNU (Single Node Upset) and DNU, while DICE (Dual I...

OBJECTIVE To investigate and compare the influence of a previous history of foot ulcers on plantar pressure variables during gait of patients with diabetic neuropathy. INTRODUCTION Foot ulcers may be an indicator of worsening diabetic neuropathy. However, the behavior of plantar pressure patterns over time and during the progression of neuropathy, especially in patients who have a clinical hi...

The scaling of shear modulus near the gelation-vulcanization transition is explored heuristically and analytically. It is found that in a dense melt the effective chains of the infinite cluster have sizes that scale sublinearly with their contour length. Consequently, each chain contributes k(B)T to the rigidity, which leads to a shear-modulus exponent dnu. In contrast, in phantom elastic netwo...

To meet the requirements of both cost-effectiveness and high reliability for low-orbit aerospace applications, this paper first presents a radiation hardened latch design, namely HLCRT. The mainly consists single-node-upset self-recoverable cell, 3-input C-element, an inverter. If any two inputs C-element suffer from double-node-upset (DNU), or if one node inside cell together with another outs...

The emergence of the theory of dynamic neural computing has made it possible to develop neural learning and adaptive schemes that can be used to obtain feasible solutions to complex control problems, such as inverse kinematic control for robotic systems. In this paper, such a neural learning scheme using a multilayered dynamic neural network (MDNN) is proposed. The basic dynamic computing eleme...
