The effect of an acyclic synthetic retinoid analogue NIK-333, on the restoration of liver mass and recovery of liver function after 70% partial hepatectomy, was compared with natural retinoids in rats in vivo. NIK-333 (0.4 mg/kg/day, p.o.)- and all-trans-retinoic acid (ATRA: 4 mg/kg/day, p.o.)-treated rats showed an approximately 1.3- and 1.2-fold increase in liver-to-body weight ratio, respect...
triamidefon is a triazole derivative, which have both fungicidal and plant growth regulator (pgr) properties, and also protect plants from several types of abiotic stresses. the influential mechanism of triamidefon on plants is not much studied. in this study effect of this compound on the drought stressed in tomato plants was investigated. the plants were subjected to 5 day interval drought st...
Super-resolution theory aims to estimate the discrete components lying in a continuous space that constitute a sparse signal with optimal precision. This work investigates the potential of recent super-resolution techniques for spectral estimation in multirate sampling systems. It is shown in the first part of this paper that, under the existence of a common supporting grid, the joint frequency...
OBJECTIVE Laryngeal reconstruction is needed to preserve laryngeal function in patients who have undergone extensive vertical or frontal partial laryngectomy. However, the procedure remains a difficult challenge. Several reconstruction techniques have been described, but these techniques pose risks of complications such as laryngeal stenosis. This study aimed to evaluate the postoperative cours...
We made partial urethral ligation in female Wistar rats to evaluate the morphological change and the reversibility of the major pelvic ganglion (MPG) neurons before and after partial urethral ligation. Thirty rats were divided into 4 groups; normal control group (N = 3), ligation group (N = 9), release of ligation group (N = 9), and sham-operated group (N = 9). WGA-HRP (horseradish peroxidase w...
We present a detail performance study of three main memory recovery algorithms: Levy and Silberschatz's Log-Driven Backups, Jagadish, Silberschatz and Sudarshan's Recovery from Main Memory Lapses, and Kumar's Partial Recovery through simulation modeling. Our results show that load balancing signiicantly aaects the performance, and group commit is an eeective way to reduce disk I/O operations in...
This paper considers a robust recovery of sparse frequencies from partial phase-only measurements. With the proposed method, sparse frequencies can be reconstructed, which makes full use of the sparse distribution in the Fourier representation of the complex-valued time signal. Simulation experiments illustrate the proposed method’s advantages over conventional methods in both noiseless and add...
Motivated by problems in signal recovery, we will investigate the distribution of the energy of the Fourier transform of a positive function on a finite group. In particular, we are able to bound from below the fraction of energy contained in various subsets of the Fourier transform of a positive function defined on a finite group. Applications to signal recovery for positive functions, as well...
We study the recovery conditions of weighted mixed l2/lp (0 < p ≤ 1) minimization for block sparse signal reconstruction from compressed measurements when partial block support information is available. We show that the block p-restricted isometry property (RIP) can ensure the robust recovery. Moreover, we present the sufficient and necessary condition for the recovery by using weighted block p...
Initial ENA images obtained with the MENA imager on the IMAGE observatory show that ENAs emanating from Earth’s magnetosphere at least crudely track both Dst and Kp. Images obtained during the storm of August 12, 2000, clearly show strong ring current asymmetry during storm main phase and early recovery phase, and a high degree of symmetry during the late recovery phase. Thus, these images esta...
