Role of Physical Properties in the Resistance of Brittle Ceramics to Failure by Thermal Buckling (1979)

An analysis is presented of the role of the physical properties which affect the thermal buckling behavior of ceramic materials for various geometric and thermal conditions. For a column with slight initial curvature or a curvature as the result of a transverse temperature gradient, expressions are derived for the maximum increase in temperature, Δ T max or transverse temperature gradient, or heat flux to which the column can be subjected to avoid failure under the influence of the bending stresses. From the solutions obtained several “thermal buckling resistance parameters” are defined for comparing the relative thermal buckling resistance of brittle materials. Numerical examples indicate that thermal buckling of brittle materials of the proper geometry can occur relatively easily.
Sensors for ceramic components in advanced propulsion systems: Summary of literature survey and concept analysis, task 3 report (1988)

The results of a literature survey and concept analysis related to sensing techniques for measuring of surface temperature, strain, and heat flux for (non-specific) ceramic materials exposed to elevated temperatures (to 2200 K) are summarized. Concepts capable of functioning in a gas turbine hot section environment are favored but others are reviewed also. Recommendation are made for sensor development in each of the three areas.

Miscibility and phase structure of binary blends of polylactide and poly(methyl methacrylate) (2002)

Abstract Blends of amorphous poly(DL‐lactide) (DL‐PLA) and crystalline poly(L‐lactide) (PLLA) with poly(methyl methacrylate) (PMMA) were prepared by both solution/precipitation and solution‐casting film methods. The miscibility, crystallization behavior, and component interaction of these blends were examined by differential scanning calorimetry. Only one glass‐transition temperature ( T g ) was found in the DL‐PLA/PMMA solution/precipitation blends, indicating miscibility in this system. Two isolated T g 's appeared in the DL‐PLA/PMMA solution‐casting film blends, suggesting two segregated phases in the blend system, but evidence showed that two components were partially miscible. In the PLLA/PMMA blend, the crystallization of PLLA was greatly restricted by amorphous PMMA. Once the thermal history of the blend was destroyed, PLLA and PMMA were miscible. The T g composition relationship for both DL‐PLA/PMMA and PLLA/PMMA miscible systems obeyed the Gordon–Taylor equation. Experiment results indicated that there is no more favorable trend of DL‐PLA to form miscible blends with PMMA than PLLA when PLLA is in the amorphous state. © 2002 Wiley Periodicals, Inc.

A DCT-Based Speech Enhancement System With Pitch Synchronous Analysis (2011)

Discrete cosine transform (DCT) has been proven to be a good approximation to the Karhunen-Loeve Transform (KLT) and has similar properties to the discrete Fourier transform (DFT). It also possesses a better energy compaction capability which is advantageous for speech enhancement. However, frame to frame variations of DCT coefficients even for a perfectly stationary signal can be observed. Therefore a DCT-based speech enhancement system with pitch synchronous analysis is proposed to overcome this problem. It reduces the drawbacks of fixed window shift and the amount of shift in the analysis window is now based on the pitch period, thus increasing the inter-frame similarities. Furthermore, a Wiener filter using the a priori signal-to-noise ratio (SNR) with an adaptive parameter is also derived and implemented as an advanced noise reduction filter. This proposed speech enhancement system is evaluated in terms of several objective measures and the experimental results demonstrate the good performance of the proposed system.

Derivation of net atomic charges from molecular electrostatic potentials (1990)

Abstract The dependence of net atomic charges, as derived from least‐squares fitting to electrostatic potentials, on molecular orientation and potential site location is critically examined. A unique rotationally invariant algorithm, in which the charges may be constrained to reproduce the molecular dipole moment, is presented and the results for several basis sets compared to previous work. Significant improvements in dipole moments derived from the unconstrained charges are noted.
Un año de serena cotidianidad (1984)

In poorly controlled diabetics, CHcorr and CRFcorr are significantly higher compared with those of the healthy subjects and patients with well-controlled diabetes. In diabetes, CHcorr and CRFcorr are correlated to HbA1c, suggesting that the biomechanical properties of the cornea are altered depending on the glucose control.
Laser Chemistry–What is Its Current Status? (1987)

Abstract In recent years, various methods have been developed to observe and to influence the course of chemical reactions using laser radiation. By selectively increasing the translational, rotational, and vibrational energies and by controlling the relative orientation of the reaction partners with tunable infrared and UV lasers, direct insight can be gained into the molecular course of the breaking and re‐forming of chemical bonds. Examples for the application of lasers include the synthesis of monomers such as vinyl chloride and polymers such as polyethylene, the synthesis of biologically active substances such as vitamin D 3 , the separation of isotopes, the removal of impurities, the production of catalysts, glasses, and ceramics, and the deposition and ablation of material on surfaces. Finally, several applications of lasers in medicine are discussed.
Generative Adversarial Reservoirs for natural video prediction (2017)

In this report, we will give a brief overview of selected deep learning technologies in the interest of developing both understanding and motivation for the use of reservoir computing and generative models. Furthermore, we will show that these concepts can be applied to the problem of natural video prediction. Influenced by previous work, we develop a novel architecture called Generative Adversarial Reservoirs (GAR). We use GARs to predict frames of videos from the UCF-101 dataset and show that although some of the quantitative evaluations for our results are below state-of-the-art, utilizing reservoirs allows our model training to converge significantly faster while still achieving qualitatively good results.
l-Deprenyl in Atypical Depressives (1984)

• We investigated the antidepressant efficacy of<i>l</i>-deprenyl (selegiline), a selective monoamine oxidase B inhibitor (MAOI), in a six-week open trial of 17 patients with atypical depression. Such patients have previously been shown to benefit from nonselective MAOIs such as phenelzine sulfate. Ten patients (59%) responded to l-deprenyl, but nine required dosages above the 10 to 20 mg/day used in previous investigations.<i>l</i>-Deprenyl was superior to six weeks of placebo administered to diagnostically similar patients in a separate double-blind study. In contrast with previous findings with phenelzine, responders to<i>l</i>-deprenyl differed from nonresponders by having lower baseline anxiety ratings. Even at high dosages, there appeared to be fewer side effects with<i>l</i>-deprenyl than with nonselective MAOIs.
Immunogenic and protective effects of the F-2 strain of feline viral rhinotracheitis virus. (1975)

The F-2 strain of feline viral rhinotracheitis (FVE) virus was administered by intramuscular (IM) injection to susceptible cats. The cats developed serum-neutralizing antibodies and were protected to a significant degree when given, by intranasal (IN) instillation challenge inoculum of a virulent strain of FVR virus.
Efficient Reinforcement Learning using Gaussian Processes (2010)

This book examines Gaussian processes in both model-based reinforcement learning (RL) and inference in nonlinear dynamic systems. First, we introduce PILCO, a fully Bayesian approach for efficient RL in continuous-valued state and action spaces when no expert knowledge is available. PILCO takes model uncertainties consistently into account during long-term planning to reduce model bias. Second, we propose principled algorithms for robust filtering and smoothing in GP dynamic systems.
An experimental electrical impedance tomography system (2002)

The design of an experimental electrical impedance tomography (EIT) system is presented. The aim of EIT is to reconstruct the internal resistance distribution of a test object (region). The project involves building a data acquisition system that applies current to the test object and measures the induced voltage responses on the boundary of that object. The measured responses are then processed using the back-projection image reconstruction algorithm to acquire an approximated image of the test object's internal resistance distribution. The laboratory experimental results showed that recognizable images can be achieved on both open and closed boundary conditions.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Helicobacter pylori : basic mechanisms to clinical cure : proceedings of the international symposium held at Amelia Island, Florida, USA, November 3-6, 1993 (1994)

Helicobacter pylori has attracted widening interest from basic scientists and clinical investigators and the information on this organism is increasing exponentially. It is now accepted that H. Pylori is the most important cause of chronic active gastritis. Furthermore, data have confirmed a marked reduction in the relapse rate of both duodenal and gastric ulcer after eradication of the organism. These important clinical observations have served as a strong stimulus to the investigation of the basic mechanisms involved in the pathogenesis of H. pylori-associated inflammation and the subsequent alterations of gastroduodenal function and gastric mucosal architecture. The book contains chapters by a multidisciplinary, international group of basic scientists and clinical investigators who focus on various microbiological aspects of H. pylori, on the role of H. pylori in peptic ulcer and gastric cancer, and the current status of therapy. The book contains the proceedings of the conference on Helicobacter pylori: Basic Mechanisms to Clinical Cure', held at Amelia Island, Florida, U.S.A., on November 3--6, 1993.

Temporal classification for historical Romanian texts (2013)

In this paper we look at a task at border of natural language processing, historical linguistics and the study of language de-velopment, namely that of identifying the time when a text was written. We use machine learning classification using lexi-cal, word ending and dictionary-based fea-tures, with linear support vector machines and random forests. We find that lexical features are the most helpful. 1

Assessment of the Wiener–Retinex process (2002)

We assess the performance of the Retinex transformation, the Wiener restoration, and the combined Wiener-Retinex process in the context of the end-to-end model of color visual-communication channels for near-surface acquisition. We extend the formulations of panchromatic imaging for the nonlinear Retinex transformation and the linear Wiener and Wiener-Retinex restoration filters to color imaging. We further assess the accuracy by which colors are restored in the cases of uniform and spatially varying irradiance levels, and the shadow depth for which color consistency is still possible with reasonable accuracy. Finally, we assess the sensitivity of these processes to perturbations in the visual channel, including the image-gathering design and the spatial support of the Retinex transformation.
Tyrosine Kinase Inhibitors (2007)

The extraordinary success of imatinib for the treatment of chronic myeloid leukemia (CML), gastrointestinal stromal tumors and subgroups of patients with hypereosinophilic syndrome and chronic myelomonocytic leukemia has greatly stimulated the development of small molecule inhibitors for targeted therapy of malignant diseases. Nothing short of a major breakthrough, imatinib has undoubtedly set a precedent and provided proof of principle for a completely new concept in cancer therapy. Unfortunately, diseases other than CML may prove more resilient to targeted tyrosine kinase inhibition, and even in CML, acquired resistance is a significant clinical problem. This chapter will review the current status of tyrosine kinase inhibitors for therapy of malignant disease. Much space will be given to imatinib, as the experience gained from the development of this agent is applicable to other conditions. The emerging concept is that for the patient's maximum therapeutic benefit, disease classifications will have to integrate therapeutic targets, and this will have implications for clinical trial design.
A performance and routability-driven router for FPGAs considering path delays (1997)

This paper presents a new performance and routability driven router for symmetrical array based field programmable gate arrays (FPGAs). The objectives of our proposed routing algorithm are two-fold: (1) improving the routability of the design (i.e., minimizing the maximum required routing channel density) and (2) improving the overall performance of the design (i.e., minimizing the overall path delay). Initially, nets are routed sequentially according to their criticalities and routabilities. The nets/paths violating the routing-resource and timing constraints are then resolved iteratively by a rip-up-and-rerouter, which is guided by a simulated evolution based optimization technique. The proposed algorithm considers the path delays and routability throughout the entire routing process. Experimental results show that our router can significantly improve routability and reduce delay over many existing routing algorithms.
NCp7 Activates HIV-1Lai RNA Dimerization by Converting a Transient Loop-Loop Complex into a Stable Dimer (1996)

Nucleocapsid protein 7 (NCp7), the human immunodeficiency virus type 1 (HIV-1) nucleocapsid protein, was shown to strongly potentiate the dimerization of the retroviral genomic RNA. This process involves the interaction of two retroviral RNA monomer subunits near their 5'-ends. A region located upstream from the splice donor site was recently identified as being responsible for the formation of dimeric HIV-1 RNA. This region appeared to be confined within a stem-loop structure, with an autocomplementary sequence in the loop. In an in vitro study of spontaneous dimer formation, we reported that the 77-402 RNA transcript forms two distinct dimers differing in their thermostability: D37 and D55. We identified D37 as a "kissing" complex structure, formed via a loop-loop interaction between the two monomers, and D55 as a double stranded structure involving all nucleotides of the stem-loop via canonical base pairing. In this report, we have characterized the role of NCp7 in the HIV-1Lai RNA dimerization process by using in vitro dimerization assays with RNA transcripts of different lengths and dimer thermal dissociation. Our results show that the nucleocapsid protein NCp7 activates RNA dimerization very likely through interaction with the kissing complex and converts it into a stable dimer. Furthermore, this NCp7-promoted conversion only occurs if the 240-280 stem-loop structure is present in HIV-1Lai RNA molecules and contains the autocomplementary G257CGCGC262 sequence. This study suggests that, under physiological conditions, an NCp7-mediated RNA conformational change is involved in the maturation of the HIV-1 RNA dimer.
Design of a low power 2.45 GHz RF energy harvesting circuit for rectenna (2013)

In this paper, design procedure and characteristics of an RF energy harvesting circuit based on single-stage voltage multiplier rectifier have been discussed and analyzed. This circuit is capable to recycle RF energy at 2.45 GHz, and by connecting to a 2.45 GHz antenna, it is possible to form a complete rectenna device. The values of output dc voltage and power according to the received RF power have been measured and the best value of load resistance to harvest maximum output dc power has been selected by simulation.
Zipf Distribution of U.S. Firm Sizes (2001)

Analyses of firm sizes have historically used data that included limited samples of small firms, data typically described by lognormal distributions. Using data on the entire population of tax-paying firms in the United States, I show here that the Zipf distribution characterizes firm sizes: the probability a firm is larger than size s is inversely proportional to s. These results hold for data from multiple years and for various definitions of firm size.
Influence of Speciation of Aqueous HAuCl<sub>4</sub> on the Synthesis, Structure, and Property of Au Colloids (2009)

We have studied the pH-dependent speciation of aqueous HAuCl4 and its influences on the synthesis, structure, and property of Au colloids. Aqueous HAuCl4 consists of [AuClx(OH)4−x]− (x ≥ 2) at low pH but [AuClx(OH)4−x]− (x < 2) at high pH. By employment of ascorbic acid as the reducing agent and sodium benzenesulfonate (SDBS) as the protecting agent, reduction of aqueous HAuCl4 at low pH leads to the synthesis of well-dispersed and uniform fine Au colloids, whereas that at high pH forms large Au colloids and ensembles of fine Au colloids. These large Au colloids and ensembles of fine Au colloids exhibit strong surface plasmon resonance in the near-infrared region. The SDBS molecules bind to the surface of Au colloids through the S element, and the charge transfer from Au atoms to S elements occurs. The charge is localized around Au atoms directly interacting with SDBS for fine Au colloids but delocalized to the entire Au colloid for large Au colloids and ensembles of fine Au colloids.
Performance Analysis Of Speed Control Of Dc Motor Using P, PI, PD And PID Controllers (2013)

In this paper deals the usage of continuous time P-I-D controllers. In the first part of the recitation, it was aimed to show the how P, P-I, P-I-D controllers change the steady state response of the closed loop systems. Moreover, the methods to tune P-I-D controllers were introduced. It was meant to show that how hard it could get to properly tune a P-I-D controller. Secondly, it was intended to show how P, P-D, P-I, and P-I-D controllers affect the transient response of the closed loop system. It was designed to show how one can gain a feature but lose the other. Thirdly, it was intended to show how one should estimate the dynamics of the continuous time plant and use proper sampling time for discrete time P-I-D controller. It was also show how changing transformation method may cause different pole locations on the z-plane. 1.
