SecA protein autogenously represses its own translation during normal protein secretion in Escherichia coli (1989)

The Escherichia coli secA gene, whose expression is responsive to the protein secretion status of the cell, is the second gene in an operon. We found that both the basal and induced levels of SecA biosynthesis are dependent on prior translation of the upstream gene, gene X, and identified two large gene X-secA transcripts. The 10-fold derepression of secA expression by protein export defects was at the translational level since no further increases in gene X or secA mRNA levels were detected during this period, and a secA-lacZ protein fusion but not an operon fusion was appropriately derepressed. Furthermore, overexpression of the SecA protein severely reduced expression of only the secA-lacZ protein fusion, indicating that SecA autogenously represses its own translation.
Transient Restless Legs-like Syndrome as a Complication of Opiate Withrawal (2003)

In most cases, restless legs syndrome (RLS) is an idiopathic disorder affecting patients of middle and older age. Usually, the intensity of symptoms is constant or progressive. Here, we describe two opiate addicts developing RLS during opiate withdrawal. Their RLS disappeared along with the remission of withdrawal symptoms. Both cases responded well to a treatment with Madopar (L-dopa plus benserazid). This observation encouraged us to perform a retrospective analysis of all cases of opiate addicts detoxified in our unit during a 5-month period. This analysis revealed 15 out of 120 patients who had described the symptoms of transient RLS emerging during opiate detoxification treatment. Transient RLS during opiate detoxification merits further interst in order to improve the treatment of sleep disturbances during detoxification and as a model of interaction of the dopaminergic and endorphine system in motor activity.
Delta-9-THC in the Treatment of Spasticity Associated with Multiple Sclerosis (1988)

Marijuana is reported to decrease spasticity in patients with multiple sclerosis. This is a double blind, placebo controlled, crossover clinical trial of delta-9-THC in 13 subjects with clinical multiple sclerosis and spasticity. Subjects received escalating doses of THC in the range of 2.5-15 mg., five days of THC and five days of placebo in randomized order, divided by a two-day washout period. Subjective ratings of spasticity and side effects were completed and semiquantitative neurological examinations were performed. At doses greater than 7.5 mg there was significant improvement in patient ratings of spasticity compared to placebo. These positive findings in a treatment failure population suggest a role for THC in the treatment of spasticity in multiple sclerosis.
AC Loss Characteristics of HTS Wires Carrying Currents With Different Waveforms (2016)

When applying high-temperature superconductor (HTS) devices in power systems, ac loss is a significant obstacle from an economic perspective. Many studies have been performed to investigate this issue, but the ac losses for different current waveforms have rarely been reported. However, in power systems, many nonlinear devices can distort current waveforms. For example, currents of converters have ripples, no-load currents of transformers are peaked waveforms, and currents of motors are normally nonsinusoidal. To investigate the influence of current waveforms on ac losses, three types of currents with different waveforms, namely, sine waves, peaked waves, and flat-topped waves, are studied using three types of HTS wires, namely, Bi2223 wire, YBCO wire with nonmagnetic substrate (Hastelloy C276), and YBCO wire whose substrate is ferromagnetic (Ni-5at.%W). The experimental results show that ac losses of HTS wires are independent of frequency when carrying sine currents and that they are dependent on frequency when carrying peaked and flat-topped wave currents. Moreover, for all types of measured wires, particularly YBCO wire with ferromagnetic substrate, measured ac losses are highly dependent on current waveforms. In the end, the authors provide a discussion for the experiment phenomenon from the point of magnetic flux creep.
A Clonal Selection Algorithm for null Synthesizing of Linear Antenna Arrays by Amplitude Control (2006)

This paper presents a clonal selection algorithm based on human immune system for null steering of linear antenna arrays by controlling only the element amplitudes. Design requirements such as the null depth level, maximum sidelobe level, and dynamic range ratio are considered in the optimization process. Several examples of Chebyshev pattern with the imposed single, multiple and broad nulls are given to show the accuracy and flexibility of the proposed clonal selection algorithm.
Amino Acids and Proteins in Relation to the Nutrition of Elderly People (1990)

In this short review some aspects of body protein and amino acid metabolism during ageing in human subjects have been explored. The picture that emerges is a progressive diminution of total body protein with ageing, due largely to a decline in the size of the skeletal muscle mass. These changes are accompanied by a shift in the overall pattern of whole body protein synthesis and breakdown, with muscle mass estimated to account for about 30% of whole body protein turnover in the young adult, as compared with a lower value of 20% or less in the elderly subject. The metabolic significance and possible functional implications of this alteration in the quantitative contribution by muscle to whole body amino acid and protein dynamics have been considered. The determination of requirements for individual essential amino acids and for total protein has been discussed, and it is evident that the data are limited and often contradictory. However, elderly individuals are more likely to be influenced by various biological, environmental and social factors, the effects of which would be generally to increase protein needs above those for younger adults. Thus, in practice, the protein needs of elderly people are probably higher than for the young. The decline in energy intake, together with its possible consequences for reduced dietary protein utilization, will also tend to increase the protein need of elderly subjects, compared with that for physically more active young adults. Until more data become available, it is recommended for food planning purposes that an appropriate protein allowance could be 12-14% of the total energy intake, for mixed protein sources characteristic of the diets of industrialized countries or the more affluent sectors of populations in developing countries. Energy intake should be at a level that meets the estimates proposed by FAO/WHO/UNU for older persons. Tentative recommendations are made herein that intakes of specific indispensable (essential) amino acids, per unit of protein need, should be similar to those for the young school-age child and they should be higher than those currently judged by international authorities (i.e. FAO/WHO/UNU) to be sufficient for maintenance of protein nutritional status in the adult. In view of (i) the increasing proportion of older individuals within technically advanced populations together with the need of this group for health care and (ii) the important role played by diet and food habits in health maintenance, and in the aetiology or progression of degenerative disease, it is vitally necessary to improve upon the current state of knowledge concerning protein and amino acid metabolism and nutrition during the later phases of our lives.

A New Minimax Design for 2-D FIR Filters with Low Group Delay (2005)

The proposed new minimax design method for 2D FIR filters is based on sequential quadratic programming (SQP). The main reason to formulate and solve the design problem in an SQP formulation is that the complementarity conditions associated with the SQP lead to a very small number of nonzero Lagrange multipliers that need to be updated in a given iteration. This in turn improves design efficiency as well as the algorithm's numerical stability, which is of critical importance as both the number of design variables and the constraints involved in a 2D design are much higher than a 1D design. Design examples with comparisons are presented to illustrate the effectiveness of the proposed method.

A dual-mode wide-band bandpass filter using slotted patch resonator with tuning stubs (2008)

In this paper, a dual-mode wide-band bandpass filter using slotted patch resonator with tuning stubs is introduced as an alternative for the miniaturization of the filter structure. The microstrip loop resonator consists of four identical patches with attached to inner corner of the square loop. The bandpass filter is based on the bandstop filter employing direct-connected feed lines on the orthogonal of the microstrip loop resonator. The introduction of two tuning stubs connecting opposite to the ports widens the passband and sharpens the stopbands.
Retarded C54 transformation and suppressed agglomeration by precipitates in TiSi2 films (2000)

We report the effects of excess Si phase on the C54 transformation and the thermal stability of TiSi2 thin films as a function of Si/Ti (x) ratio. The resistivity and x-ray diffraction data of TiSix(x=2.1–2.4) films showed a retardation of C54–TiSi2 transformation with incremental molar ratio x; the TiSix (x=2.1–2.3) films were completely transformed to C54-TiSi2 with rapid thermal annealing (RTA) of 750 °C, while the TiSix (x=2.4) films were transmuted to C54–TiSi2 over the RTA of 800 °C. Transmission electron microscopy study revealed that the growth of Si precipitates in the Si-rich TiSix films competes with the grain growth during the transformation of C49 to C54 TiSi2 phase, resulting in the increase of C54 transformation temperature. An excellent sheet resistance (Rs) and its standard deviation in concert with a reliable gate oxide integrity were attained from the Si-rich TiSi2/polycrystalline-Si (poly-Si) structure up to the solid state annealing of 850 °C for 60 min. These attributes are due to the reduced solid state reaction at TiSi2/Si interface and the suppressed TiSi2 agglomeration by Si precipitates. The average Rs of the 0.12-μm-wide TiSi2(800 Å)/poly-Si gate lines is lower than 4.5 Ω/□, demonstrating a robust gate electrode structure for gigabit scale device application.

Changes in the reflectivity of metallic films as a result of heating with short laser radiation pulses (1974)

An investigation was made of the reflectivity of opaque metallic films during and after illumination with nanosecond laser pulses. The reduction in the reflectivity was interpreted on the basis of the Drude–Zener theory allowing for the temperature dependence of the electron-phonon scattering. The experimental and calculated results were compared.
Polymorphisms of ACE2 Gene are Associated With Essential Hypertension and Antihypertensive Effects of Captopril in Women (2007)

ACE2 appears to counterbalance the vasopressor effect of angiotensin I converting enzyme (ACE) in the reninangiotensin system. We hypothesized that ACE2 polymorphisms could confer a high risk of hypertension and have an impact on the antihypertensive response to ACE inhibitors. The hypothesis was tested in two casecontrol studies and a clinical trial of 3,408 untreated hypertensive patients randomized to Atenolol, Hydrochlorothiazide, Captopril, or Nifedipine treatments for 4 weeks. ACE2 rs2106809 T allele was found to confer a 1.6-fold risk for hypertension in women (95% confidence interval (CI), 1.132.06), whereas when combined with the effect of the ACE DD genotype, the risk was 2.34-fold (95% CI, 1.754.85) in two independent samples. The adjusted diastolic blood pressure response to Captopril was 3.3 mm Hg lower in ACE2 T allele carriers than in CC genotype carriers (P=0.019) in women. We conclude that the ACE2 T allele confers a high risk for hypertension and reduced antihypertensive response to ACE inhibitors.
Copper-Catalyzed Aerobic C(sp<sup>2</sup>)–H Functionalization for C–N Bond Formation: Synthesis of Pyrazoles and Indazoles (2013)

A simple, practical, and highly efficient synthesis of pyrazoles and indazoles via copper-catalyzed direct aerobic oxidative C(sp(2))-H amination has been reported herein. This process tolerated a variety of functional groups under mild conditions. Further diversification of pyrazoles was also investigated, which provided its potential for drug discovery.
A Framework for Condition Monitoring and Condition Based Maintenance (2007)

This paper discusses a framework for determining appropriate condition based maintenance policy for an industrial system. The framework can be considered as providing practitioners with guidelines for condition based maintenance (CBM) management or as the first step in the development of an expert system for CBM management. The framework proposes that components of the system of interest be classified using multi-dimensional Pareto analysis, with this classification then indicating appropriate maintenance actions. For a particular component, condition based maintenance may then be an appropriate action. In this case, it is proposed that a binary decision tree is used to suggest an appropriate condition based maintenance decision model for the component. Such decision models are briefly reviewed. The ideas in the paper are illustrated throughout using examples from condition based maintenance and maintenance modelling in general.
A low complex adaptive algorithm for antenna beam steering (2011)

An adaptive antenna system consists of a combination of multiple antenna elements with a signal-processing capability to optimize its radiation and/or reception pattern automatically in response to the signal environment. In a telecommunication system, adaptive antenna system is the port through which radio frequency (RF) energy is coupled from the transmitter to the environment and, in reverse, to the receiver from the environment. In this paper, an efficient and simple adaptive beam steering technique is presented. The proposed method is based on Least Mean Square (LMS) algorithm, provides a comprehensive and detailed treatment of the signal model used for beam forming. In order to improve the convergence rate of LMS algorithm in smart antenna system, this paper proposes the Block Based Normalized LMS (BBNLMS) algorithm. The performance of the BNLMS algorithm in the presence of Multi path effects and multiple users is analyzed using MATLAB simulations. Simulation results confirm that the convergence rate and error reduction of BBNLMS is superior than conventional LMS algorithm.
Bayesian GAN (2017)

Generative adversarial networks (GANs) can implicitly learn rich distributions over images, audio, and data which are hard to model with an explicit likelihood. We present a practical Bayesian formulation for unsupervised and semi-supervised learning with GANs. Within this framework, we use stochastic gradient Hamiltonian Monte Carlo to marginalize the weights of the generator and discriminator networks. The resulting approach is straightforward and obtains good performance without any standard interventions such as feature matching, or mini-batch discrimination. By exploring an expressive posterior over the parameters of the generator, the Bayesian GAN avoids mode-collapse, produces interpretable and diverse candidate samples, and provides state-of-the-art quantitative results for semi-supervised learning on benchmarks including SVHN, CelebA, and CIFAR-10, outperforming DCGAN, Wasserstein GANs, and DCGAN ensembles.
Floating codes with good average performance (2010)

Floating codes are codes for multi-level flash memories. There are two main properties which those codes have, the worst-case block erasure period and the average block erasure period. Codes with large average block erasure period can be constructed from the Gray code. First it is shown that a construction method for the floating codes can be interpreted by using labelled graphs. Floating codes are proposed for cases (a) n = 5 and k = 4, l = 2, q >; 2; (b) n = 8, k = 4, I = 2, q>; 2, where n is the number of cells in a block, k the number of information variables, I the number of levels of information variables and q the number of levels of cells. It is shown that if input data do not distribute uniformly, then the frequency of block erasure is low when the proposed code is used.
A novel ring-based triple-push 0.2-to-34 GHz VCO in 0.13μm CMOS technology (2008)

A novel ring-based triple-push voltage-controlled oscillator (VCO) with a continuous range from 0.2 to 34 GHz is proposed and realized using a commercial 0.13-μm 1P8M CMOS process. The output power of the VCO is −18 dBm with only ±2 dB variation in the full band. The fundamental rejection is more than 15 dB, and the second harmonic rejection is more than 25 dB. This VCO achieves the widest continuous tuning range reported to date.
A kilohertz repetition rate 1.9 mu m H/sub 2/ Raman oscillator (1989)

Raman conversion of a high-repetition-rate Q-switched Nd:YAG laser using a gaseous H/sub 2/ Raman medium is reported. With a H/sub 2/ cell placed in a focusing intracavity Raman oscillator, 3 W of average power at 1.9 mu m was obtained from a 15-W 1.06- mu m laser operating at 2 kHz. Although the pump beam was multimode, the Stokes output was diffraction limited. At kilohertz repetition rates, conversion efficiencies were improved with a flowing gas cell which substantially reduced the thermal lensing effect in the Raman medium. A rate equation approach was used to model the intracavity conversion process.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
On Design of a Backplate Used in a Hearing Aid (2000)

In this work topology optimization is used to optimize the compliance or the eigenfrequencies of prestressed plates. The prestress is accounted for by including the force equiva-lent to the prestressing and adding the initial stress stiffness matrix to the original stiffness matrix. The calculation of the sensitivities is complicated because of the initial stress stiff-ness matrix, but the computational cost can be kept low by using the adjoint method. The topology optimization prob-lem is solved using the SIMP method (Simplified Isotropic Material with Penalization) in combination with MMA (Method of Moving Asymptotes). Numerical examples of minimizing compliance or maximizing the first eigenfre-quency of plates are given. The example is a MEMS (Micro Electro Mechanical Systems) application involving a back-plate used in a microphone for a hearing aid.
