Photoemission study of the passivation of GaAs in a nitrogen multipolar plasma (1987)

Abstract Passivation of III–V compounds remains a challenging problem for surface physicists. A route to passivation including a cleaning step and the formation of a nitride is presented. The chemical and electrical states of the surface are probed using photoelectron spectroscopy in various modes. In this paper we concentrate on the chemical and structural aspects of this problem. Low-ion-temperature plasmas (such as the multipolar plasma used here) containing a high proportion of atomic species yield very sharp interfaces and good electrical properties. An attempt is made to interpret these effects from the photoemission data.
COLIC IN INFANTS (1956)

This may well have been a historic occasion because so far as I have been able to ascertain, this was the first time that a symposium on the important subject of in infants had ever been presented at a national meeting of pediatricians. Due to the fact that little attention is paid to in institutions, this disorder has rarely received the attention of the full-time academic pediatrician (unless he has experienced it in his own family). For that reason interns and residents all too commonly encounter this frustrating problem only on starting private practice when it becomes a matter of great importance and concern. Our fundamental knowledge of what is termed colic is so uncertain that it is appropriate in discussing this subject to quote a remark by Tenney, And so it is with colic; maybe there is no such thing, but there is certainly something that makes perfectly healthy babies cry almost unbelievably loud and long without interfering with their perfect health. For the purposes of this discussion may be defined as a symptom complex of early infancy characterized by evidence of intermittent abdominal pain of varying degrees of severity for which no organic or obvious physiological cause can be regularly demonstrated. For discussion of this subject pediatricians were selected who for the most part, because of part-time positions on the teaching staffs of medical schools, would be expected to have academic as well as practical interest in this problem and who, because of their varying interests, have considered the problem from different viewpoints. Attention is directed particularly to the fact that among the 8 papers presented at this symposium only 2 were by pediatric allergists, Dr. Fries9 and Dr. Ratner9s.
GPMS, a general purpose memory management system---user's memory---that is. (1976)

GPMS is a keyword based information entry and retrieval system. The data consist of a collection of messages, where a message is an arbitrary quantum of free text. Users supply both keywords and message body. Keywords are hashed into an association file while messages, which receive unique chronological names, reside in a message file. A simple English-like query package is included.
A case-based approach to network intrusion detection (2003)

This paper reports progress on creating a case-based implementation of the well-known Snort intrusion detection system. Snort is a simple rule-based system that is known to suffer limitations, including both failure to detect certain kinds of intrusions and the frequent raising of false alarms. We believe that a case-based reasoning approach can provide a framework in which to incorporate more sophisticated artificial intelligence techniques that will help overcome some of these limitations. In addition, the present system is intended to apply more generally to other aspects of network security, as well as other domains related to protecting the nation's critical infrastructure. The system is being built using the modern software engineering technique known as "adaptive" or "reflective architectures," which will make it easily adaptable to other kinds of problem domain.

Using a Reflective Architecture to Validate Object-oriented Applications by Fault Injection (1998)

This text presents FIRE, a tool developed to support reflective fault injection in order to validate objectoriented applications. FIRE was implemented using OpenC++1.2, and its aim is to validate C++ and OpenC++1.2 applications. Some issues about the use of FIRE in fault injection experiments are shown here. Keywords Software-implemented fault injection, object-oriented systems, reflective programming , metaobjects. INTRODUCTION The objective of software fault injection techniques is to modify the hardware/software state of the system under software control, thus causing the system to behave as if any fault was present [5]. These techniques are being increasingly used to validate dependability properties of software systems, so several tools have been developed. Such tools present several injection methods, which vary according to the fault injection destination, (fault-tolerant mechanisms, application, operating system, or communication channels) and the difficulties or facilities...
Coaxial Transmission Lines, Related Two-Conductor Transmission Lines, Connectors, and Components: A U.S. Historical Perspective (1984)

This Special Issue of the Transactions on Microwave Theory and Techniques in observance of the first 100 years of the IEEE has an especially interesting parallel for the history of guided electromagnetic (EM) waves. It was in this decade 100 years ago that Heinrich Hertz, a German professor of physics, carried out his original experiments which demonstrated the reality of the Faraday-Maxwell theory of the wave nature of light and electricity and the central thesis that they are essentially the same. According to Hertz, the result of the experiments is to confirm the fundamental hypotheses of the theory. He acknowledged the problems of following Maxwell's difficult style, with its "unwonted mathematical difficulties," and of not always being quite certain of having grasped the physical significance of Maxwell's statements.
Skeletal Myoblasts for Cardiac Repair (2010)

Stem cells provide an alternative curative intervention for the infarcted heart by compensating for the cardiomyocyte loss subsequent to myocardial injury. The presence of resident stem and progenitor cell populations in the heart, and nuclear reprogramming of somatic cells with genetic induction of pluripotency markers are the emerging new developments in stem cell-based regenerative medicine. However, until safety and feasibility of these cells are established by extensive experimentation in in vitro and in vivo experimental models, skeletal muscle-derived myoblasts, and bone marrow cells remain the most well-studied donor cell types for myocardial regeneration and repair. This article provides a critical review of skeletal myoblasts as donor cells for transplantation in the light of published experimental and clinical data, and indepth discussion of the advantages and disadvantages of skeletal myoblast-based therapeutic intervention for augmentation of myocardial function in the infarcted heart. Furthermore, strategies to overcome the problems of arrhythmogenicity and failure of the transplanted skeletal myoblasts to integrate with the host cardiomyocytes are discussed.

Article Zur selektiven Veresterung von D-Mannit: Darstellung grenzflächenaktiver D-Mannit-partialester höherer Fettsäuren was published on September 1, 1968 in the journal Tenside Surfactants Detergents (volume 5, issue 9-10).
On automatic design of data organization (1970)

A number of research efforts have contributed to the beginning of a methodology for the automatic design of large-scale information processing systems (IPS). See for instance Nunamaker. One facet of study in these efforts is the design of data organization.
Generic diagnostic knowledge acquisition tool (1988)

This paper describes a knowledge acquisition methodology designed for the diagnostic domain. The conventional interaction between domain expert and knowledge engineer in crafting the knowledge base for the particular expert system shell used has several well known disadvantages. An object based approach, which eliminates the need for knowledge engineering is proposed. The domain knowledge is represented by suitably defined objects that allow for communication in a language most familiar to the domain expert. The representation builds on the notion of a domain knowledge state space and the mapping of it to the objects.
Face Recognition using SOM Neural Network with Different Facial Feature Extraction Techniques (2013)

This paper deals with 3 different techniques for feature extraction of image. Face detection is a necessary first-step in face recognition systems, with the purpose of localizing and extracting the face region from the background. The Self-Organizing Map (SOM) Neural Network has been used for training of database and simulation of FR system. The developed algorithm for the face recognition system formulates an image-based approach, using discrete wavelet transform (DWT), discrete cosine transform (DCT) and Sobel edge detection, simulated in MATLAB. Simulation results are very promising.
A microprocessor-based device for synthesis of R-R interval values during ambulatory monitoring (1983)

A microprocessor-based system devoted to ambulatory monitoring of heart-rate variability (HRV) is described. Mainly it measures R-R intervals after QRS detection and provides a real-time quantification of the HRV. The concept of derived successions and a suitable set of graphical summaries are used. The hardware is based on CMOS technology; the mobile part of the system is battery operated. The results are printed-out by the fixed part of the system, they can also be fed into a general-purpose computer. Other applications of the system are suggested.
Pilot-Plant Production of Protease by <i>Alternaria tenuissima</i> (1967)

Agar slants of a selected Alternaria tenuissima strain were illuminated to give conidia suitable for further propagation. For production of protease with an optimal caseolytic activity in the region of pH 8 to 10, the fungus was cultivated in steel fermentors with 6- and 60-liter working capacity. Maximal activity, 1.5 enzyme units per liter, was attained in a medium based on liver after about 60 hr of cultivation. The protease was secreted parallel with, or slightly after, the main growth phase. The process could be run favorably with a relatively low aeration rate. The pH of the culture decreased during the process from 7.0 to about 6.3. This was the optimal region also when pH was kept constant by automatic pH control. Optimal temperature was about 28 C, which resulted in a maximal productivity of 0.057 enzyme units per liter per hr during the protease secretion phase. Replacement of the liver in the medium with skim milk, meat scrap, or rapeseed oil meal resulted in a decrease of the protease yield.
NASA OAST perspective (1984)

An advanced OTV is one of a number of advanced STS vehicles that the NASA OAST Space Systems Division Transportation Systems Office identified as candidates for future vehicle development. Vehicle requirements as well as technology needs and need dates were established and technology programs initiated to support those potential developments in a timely manner. It is assumed that advanced OTV will be space based and fully reusable for low cost operations, use aeroassist for return to low-Earth-orbit, and evolve to a man-rated system. The propulsion system will need to maintain high performance over a wide thrust range for mission flexibility, ranging from the transfer of large, acceleration limited structures from LEO to GEO, to demanding high reliability round-trip manned missions. Technology advances are needed in propulsion, aerobraking, low-gravity cryogenic fluid management, and in environmentally compatible, low-loss cryogenic tankage. In addition, diagnostic instrumentation for monitoring the health of on-board components and systems, and automated check-out capability will enhance low-cost space based OTV operations.
Risk Factor of Peripheral Neuropathy among NewlyDiagnosed Type 2 Diabetic Patients in Primary CareClinic (2012)

Background: Diabetic foot is one of the most serious complications of diabetes leading to poor quality of life even a higher risk of mortality. Diabetic patients with peripheral neuropathy are at a higher risk of developing foot infection and ulcer. It causes a major source of morbidity, a leading cause of hospital bed occupancy and account for substantial health care, costs and resources. Objectives: The aim of this study was to identify the risk factors for peripheral neuropathy among newly diagnosed Type 2 diabetic patient in Primary Care Clinic, Kota Bharu, Kelantan, Malaysia. Methods: This was a part of the cross sectional study to assess the prevalence of peripheral neuropathy among newly diagnosed T2DM patients attending Primary Care Clinic in Kota Bharu district. It involved of 254 patients which were selected from July 2009 until June 2010. A set of case report form consist of socio demographic data, clinical examination and investigation result was used. Diabetic peripheral neuropathy is present if patient unable to feels the monofilament 5.07(10g) to one or more sites tested. Results: The mean (SD) age of participants was 53.3(9.06) years. About 8.7% of participants were diagnosed to have peripheral neuropathy. The factors that contribute to the development of peripheral neuropathy among newly diagnose type 2 diabetes were age of the patients (p < 0.001) and the presence of retinopathy (p= 0.001). Conclusion: The detection of the peripheral neuropathy should be done to all T2DM patients at the diagnosis, so that the preventive measures could be taken to prevent diabetic foot disease. Patients who have retinopathy should also screen for neuropathy.
The Structure of Electrodeposited Copper Alloys (1938)

A photomicrographic study is presented of copper deposited from cyanide solutions containing lead, thallium, silver, cadmium, tin, nickel, zinc, and cobalt. Lead had the most pronounced brightening effect and silver the greatest roughening effect. Cathodic polarization changes caused by foreign metallic cations were determined and it was found that lead caused the most pronounced increase and silver the greatest decrease in cathodic polarization. A discussion on interference effects of foreign metallic cations is presented and periodic deposition was shown to be coincident with potential‐time variations. Two types of treeing mechanisms were observed: (1) banded successive nodularization, and (2) rapid directional growth similar to dendrite formation. Complications involved in the interpretation of interference effects from metallo‐ graphic data are discussed.
Amyloid protein SAA is an apoprotein of mouse plasma high density lipoprotein. (1979)

Mouse plasma contains a protein antigenically related to mouse protein AA, the principal protein derived from tissue deposits of amyloid substance in mice. In this work the plasma antigen, SAA, was found mainly as a high molecular weight form (2 x 10(5)) residing for the most part in the density interval 1.063-1.21 g/cm3 (high density lipoprotein, HDL); the largest amount of SAA, absolute and relative to total protein, was found in the density interval 1.125-12.1 g/cm3 (HDL3). When apoproteins of the mouse HDL obtained by delipidation of the lipoprotein particles were chromatographed in acid/urea, the antigenic activity appeared in the 10,000- to 15,000-dalton portion of the apoprotein complex. In these characteristics mouse SAA closely resembles human SAA and the behavior of the protein related to amyloid protein AA indicates that is one of the apoproteins of the HDL complex in both species. Therefore we suggest that it be named apoSAA.

P/G Pad Placement Optimization: Problem Forumulation for Best IR Drop (2005)

IR drop minimization has become very difficult for non-flip chip packaged designs due to technology shrink and increasing design frequencies. Different constituents of IR drop on a wire-bond chip (where pads are placed at the die-periphery) are "package-ball to bond-pad drop", "bond-pad to internal global power ring drop" and "internal local power ring drop". Optimization equations are developed to minimize IR drop from the lead-finger-frame to the standard cell power rails on the die by placing the P/G pads optimally for a given power network. Further, optimization equations are developed to minimize trace wire length on package for P/G pads drawing highest current. The cost functions in the optimization equations target minimum IR drop for those regions of the chip that are switching at maximum speed. By use of our cost function for optimizing P/G pad placement, results on the representative chip with about 15 million gates and several hard macros show an improvement of 10% to 15% in worst IR drop value for different floorplans (one floorplan with uniform power density, and the other floorplan with maximum power density much higher than the average power density of the design).
Design and experimental verification of real-time mechanisms for middleware for networked control (2010)

Networked control systems give rise to several new problems which need to be resolved for successful development of such control systems. One of the most important is to develop a software framework with appropriate architecture and mechanisms for rapid, reliable, and evolvable distributed control applications. In particular, timeliness in the interaction among entities which constitute the overall control loop is one of the crucial requirements that must be provided by the platform. We discuss the issues related to the design and implementation of such mechanisms to support timeliness requirements. We describe the design of real-time enhancements to Etherware, a middleware for distributed control systems that has been developed in the Information Technology Convergence Laboratory at the University of Illinois. We further evaluate the performance of the designed middleware through a distributed inverted pendulum control application. We demonstrate the satisfactory performance of the unstable system even under several sophisticated run-time functionalities such as component upgrade and migration. We demonstrate that stability is maintained even under each of these tests as well as a computational stress test.
Reconstruction of high resolution 3D visual information (1994)

Given a set of low resolution camera images, it is possible to reconstruct high resolution luminance and depth information, specially if the relative displacements of the image frames are known. We propose iterative algorithms for recovering hash resolution albedo and depth maps that require no a priori knowledge of the scene, and therefore do not depend on other methods, as regards boundary and initial conditions. The problem of surface reconstruction has been formulated as one of expectation maximization (EM) and has been tackled in a probabilistic framework using Markov random fields (MRF). As for the depth map, our method directly recovers surface heights without refering to surface orientations, while increasing the resolution by camera jittering. Conventional statistical models have been coupled with geometrical techniques to construct a general model of the world and the imaging process.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Fluorine-19 NMR investigations of the catalytic mechanism of phosphoglucomutase using fluorinated substrates and inhibitors (1992)

The complexes of phosphoglucomutase with a number of fluorinated substrate analogues have been investigated by 19F NMR and the effects of the binding of Li+ and Cd2+ to these complexes determined. Very large downfield chemical shift changes (-14 to -19 ppm) accompanied binding of the inhibitors 6-deoxy-6-fluoro-alpha-D-glucopyranosyl phosphate and alpha-glucosyl fluoride 6-phosphate to the phosphoenzyme. Smaller shift changes were observed for ligands substituted with fluorine at other positions. Addition of Li+ to enzyme/fluorinated ligand complexes caused a 10(2)- to 10(3)-fold decrease in ligand dissociation constants as witnessed by the change from intermediate to slow-exchange conditions in the NMR spectra. Measurement of the 19F NMR spectra of complexes of the Li(+)-enzyme with each of the fluoroglucose 1-phosphates and 6-phosphates has provided some insight into the environment of each of these fluorines (thus also parent hydroxyls) in each of the complexes. Results obtained argue strongly against a single sugar binding mode for the glucose 1- and 6-phosphates. Two enzyme-bound species were detected in the 19F NMR spectra of the complexes formed by reaction of the Cd(2+)-phosphoenzyme complex with the 2- and 3-fluoroglucose phosphates. These are tentatively assigned as the fluoroglucose 1,6-bisphosphate species bound in two different modes to the dephosphoenzyme. Only one bound species was observed in the case of the 4-fluoroglucose phosphates.(ABSTRACT TRUNCATED AT 250 WORDS)
Immunomodulatory activities of Punarnavine, an alkaloid from<i>Boerhaavia diffusa</i> (2009)

The effect of Punarnavine on the immune system was studied using Balb/c mice. Intraperitoneal administration of Punarnavine (40 mg/kg body weight) was found to enhance the total WBC count on 6(th) day. Bone marrow cellularity and number of alpha-esterase positive cells were also increased by the administration of Punarnavine. Treatment of Punarnavine along with the antigen, sheep red blood cells (SRBC), produced an enhancement in the circulating antibody titer and the number of plaque forming cells (PFC) in the spleen. Maximum number of PFC was obtained on the 6(th) day. Punarnavine also showed enhanced proliferation of splenocytes, thymocytes and bone marrow cells both in the presence and absence of specific mitogens in vitro and in vivo. More over administration of Punarnavine significantly reduced the LPS induced elevated levels of proinflammatory cytokines such as TNF-alpha, IL-1beta, and IL-6 in mice. These results indicate the immunomodulatory activity of Punarnavine.
