A 1.2 Gbps CMOS DFE receiver with the extended sampling time window for application to the SSTL channel (2003)

A CMOS DFE (decision feedback equalization) receiver with a negligible overhead in chip area and power consumption was implemented by cross-coupling the outputs of a conventional 2-way interleaving receiver to the other side of the input. Application of this receiver to the SSTL interface channel showed the increase of sampling time window by 60 /spl sim/120% at data rates from 800 Mbps up to 1.2 Gbps. Chip area and power consumption are 80/spl times/100 /spl mu/m and 2.5 mW respectively with a 0.25 /spl mu/m 1-poly 5-metal CMOS process at the supply voltage of 2.5 V.

Learning Goal-Directed Behaviour (2017)

Learning behaviour of artificial agents is commonly studied in the framework of Reinforcement Learning. Reinforcement Learning gained increasing popularity in the past years. This is partially due to developments that enabled the possibility to employ complex function approximators, such as deep networks, in combination with the framework. Two of the core challenges in Reinforcement Learning are the correct assignment of credits over long periods of time and dealing with sparse rewards. In this thesis we propose a framework based on the notions of goals to tackle these problems. This work implements several components required to obtain a form of goal-directed behaviour, similar to how it is observed in human reasoning. This includes the representation of a goal space, learning how to set goals and finally how to reach them. The framework itself is build upon the options model, which is a common approach for representing temporally extended actions in Reinforcement Learning. All components of the proposed method can be implemented as deep networks and the complete system can be learned in an end-to-end fashion using standard optimization techniques. We evaluate the approachon a set of continuous control problems of increasing difficulty. We show, that we are able to solve a difficult gathering task, which poses a challenge to state-of-the-art Reinforcement Learning algorithms. The presented approach is furthermore able to scale to complex kinematic agents of the MuJoCo benchmark.
THE EFFECT OF 2-BUTYL-CYANOACRYLATE ADHESIVE IN OSTEOTOMIES AND BONE GRAFTS IN RABBITS: MACROSCOPIC AND RADIOGRAPHIC CHARACTERISTICS (2012)

The adhesive was not completely metabolized within 16 weeks. There was clinical consolidation of the osteotomies within four weeks. The adhesive stabilized the bone graft within the first weeks and did not interfere with the consolidation of the osteotomies, or the integration of the bone graft in radiographic observations.
Determinación de pH y proteínas totales en saliva en pacientes con y sin aparatología ortodóncica fija (estudio piloto) (2022)

Este estudio tuvo como objetivo determinar la concentración de las proteínas totales y pH en muestras de saliva humana, en pacientes de 15-25 años con tratamiento de ortodoncia. Se seleccionaron pacientes de la Clínica de Ortodoncia del Posgrado de la Facultad de Odontología de la UNAM, con y sin aparatología ortodóntica. Se les pidió no comer, beber, fumar y realizar higiene bucal dos horas antes de la recolección de saliva estimulada y no estimulada; las muestras se tomaron bajo las mismas condiciones, por el mismo investigador entre las 8 y 10 a.m. Las muestras fueron almacenadas a menos 20ºC, posteriormente se utilizó espectrofotometría mediante la técnica de Bradford para la determinación de proteínas totales y la medición del pH salival se realizó, utilizando un potenciómetro. Dentro de los resultados se encontró que existieron diferencias estadísticamente significativas entre el grupo control y el experimental en el pH de la saliva total no estimulada (t de Student P
An extensible administration and configuration tool for Linux clusters (1999)

This project addresses the lack of system administration tools for Linux clusters. The\ngoals of the project were to design and implement an extensible system that would\nfacilitate the administration and configuration of a Linux cluster. Cluster systems are\ninherently scalable and therefore the cluster administration tool should also scale well to\nfacilitate the addition of new nodes to the cluster.\nThe tool allows the administration and configuration of the entire cluster from a single\nnode. Administration of the cluster is simplified by way of command replication across\none, some or all nodes. Configuration of the cluster is made possible through the use of a\nflexible, variables substitution scheme, which allows common configuration files to\nreflect differences between nodes. The system uses a GUI interface and is intuitively\nsimple to use.\nExtensibility is incorporated into the system, by allowing the dynamic addition of new\ncommands and output display types to the system. Through the use of a menus\nconfiguration file the system is easily extended to include additional commands. This can\nbe accomplished without reprogramming for the majority of commands. An API has been\nprovided to allow different types of component to be displayed on the main GUI panel.\nThe system thus exhibits extensibility in supporting different types of display\ncomponents such as text or graphics. This extensible scheme can then be used to support,\nfor example, graphical output.\nThrough the use of a configuration file for the nodes in the system, the system can scale\nwell. New nodes are easily added through a single entry in this configuration file.\nScalability is also incorporated into the design of the system, whereby as much work as\npossible is distributed to the server nodes.
Study on determining methods of intracellular riboflavin of yeast (2004)

Intracellular riboflavin in both standard solution and yeast extract was determined by using high performance liquid chromatography (HPLC), fluorometry and spectrophotometry, respectively. The results showed that the three methods have good linearity and repetition for standard samples. But for years extract, the recovery, veracity and recurity of fluorometry were better than that of other two methods. Thus, the fluorometry was regarded as a suitable method for determining intracellular riboflavin of yeast.
A SOCIOLOGICAL INVESTIGATION OF THE CAUSES, EFFECTS AND SOLUTIONS TO THE PROBLEM OF EXAMINATION MALPRACTICE: THE OPINIONS OF THE CRAWFORD UNIVERSITY STUDENTS IN NIGERIA (2014)

With 90 students sampled from Crawford University in Nigeria, this research article investigated the causes, effects and solutions to the problems of examination malpractice in Nigeria. Undue emphasis on certificates, fear of failure in examinations, inadequate preparation for examination, teachers’ related factors and societal factor of corruption were identified as the causes of examination malpractice. Discouragement of the hard working life style, turning out half –baked graduates, denial of innocent students the opportunities to be admitted into tertiary institution, decrease in job efficiency and lowering of the standard of education were the effects cited by the participants. The participants were of the opinions that de-emphasizing paper and certificate qualifications, proper funding of the educational system and helping the students to gain self –confidence would go a long way in putting an end to the menace of examination malpractice in Nigeria. Based on their opinions, it is recommended that government should set up a committee that would see to the emphasis on skills, competence and intellect of the individuals as a way of rating them, rather than on certificates alone. 70% for skills, competence and intellect and 30% for certificates in rating was advocated. Proper funding of the educational system by the government and well- to- do people in the society and proper guidance and counseling of the students were also part of the recommendation made in the efforts to sanitalize the educational system in Nigeria from the problem of examination malpractice, which has eaten deep into the bone marrow of Nigerian educational system.
Obesity, binge eating and psychopathology: Are they related? (1994)

Obese female subjects with binge eating disorder BED; (N = 107) completed the Beck Depression Inventory, Symptom Checklist-90, Inventory of Interpersonal Problems, and Rosenberg Self-Esteem Scale. Subjects were divided into moderate or severe binger on the basis of scores on the Binge Eating Scale, and grouped into moderately or severely obese by performing a median split on their weights. Spearman correlational analyses were performed to determine the relationship between psychopathology and obesity and psychopathology and binge eating. Analyses of variance (ANOVAs) were then performed using scores on the psychological measures with subjects grouped both by severity of obesity and severity of binge eating. The results indicated that in our sample, obesity and scores on the measures of psychiatric symptomatology were unrelated. However, a significant positive relationship was found between binge eating severity and degree of psychiatric symptomatology. We suggest that binge eating may account for the observed relationship between obesity and psychopathology reported in previous studies. We discuss the importance of assessing BED when conducting research with obese individuals.
Biochemistry and Molecular Biology of Soybean Seed Storage Proteins (2000)

Soybean (Glycine max[L.] Merr.) is one of the principle field crops grown in the United States. From a crop with no significant economic value at the turn of this century, soybeans have made remarkable strides in U.S. agriculture, claiming the stature of the number two U.S. cash crop. Soybean is an important source of edible vegetable oil and protein throughout the world and is used in a multitude of food and industrial applications. Even though soybeans are a rich source of protein for livestock and humans, the nutritional quality of soybean proteins is not optimal. Some of the problems associated with soybean proteins include (1) presence of anti-nutritional factors such as trypsin inhibitor, (2) undesirable beany flavor, (3) elicitation of allergic reactions in susceptible individuals, (4) poor digestibility of soybean proteins, and (5) deficiency in sulfur-containing amino acids. As a consequence, concerted efforts are underway to improve the overall nutritive value of soybean proteins by both classical plant breeding and molecular biological approaches. This review article summarizes the current knowledge on the biochemistry and molecular biology of soybean seed storage proteins. Recent advances in the genetic improvement of amino acid composition of seed storage proteins are highlighted. The review also includes some recent achievements in modifying soybean seed composition.
Observation of intrinsic bistability in resonant tunneling structures (1987)

A simple quantum system, the semiconductor-based double-barrier resonant-tunneling structure, exhibits intrinsic bistability which we attribute to the feedback dependence of the energy of the electronic states in the well on the tunneling current density.
Spectral Micro-CT Imaging of Ex Vivo Atherosclerotic Plaque (2012)

The goal of this research was to demonstrate the potential of spectral CT for the discrimination of vulnerable atherosclerotic plaques. It was proposed that spectral CT has the potential to identify the presence of specific markers for vulnerable plaques: iron deposits and lipid core. A spectral micro-CT system incorporating the latest Medipix spectroscopic photon- counting detectors was commissioned for this purpose. Using spectroscopic methods developed with this system, it was possible to distinguish the presence of iron deposits and lipid core within ex vivo atherosclerotic plaques. Atherosclerosis or hardening of arteries is a systemic disease of the vessel wall that occurs in the aorta, carotid, coronary and peripheral arteries. It is characterised by the deposition of calcified plaques on the innermost layer of the artery wall. Vulnerable plaques are unstable, prone to rupture and put the person at risk of cardiovascular events and strokes. Factors that may lead to plaque instability are lipid content and iron deposits. This preclinical study is a precursor to the development of a clinical technique that will enable vulnerable atherosclerotic plaques to be identified in vivo prior to treatment or removal. Following a preliminary study on atherosclerotic plaques with a prototype system, the MARS-CT3 spectral micro-CT system incorporating Medipix3 was developed and commissioned for further plaque studies. The spectral CT data sets acquired by this system were assessed visually for morphology and analysed for material composition using a linear algebra method. The results were correlated with photography and histology (the histology is the current gold standard). The presence of iron and lipid can be differentiated from the background soft-tissue using a linear algebra method. However the quantification of iron in the presence of calcium is not currently possible without additional data or constraints. Nevertheless the presence of iron deposits within the plaques can be distinguished in the high resolution MARS-CT images and has been correlated with photographic and histological evidence. Thus, using the high spatial resolution spectral data from MARS-CT, the discrimination of lipid core and iron deposits within ex vivo advanced human atherosclerotic plaques is feasible. This may provide the basis for the development of a clinical technique that will identify vulnerable plaques in vivo by high resolution spectral CT.
The Relationships between RBE and LET for Different Types of Lethal Damage in Mammalian Cells: Biophysical and Molecular Mechanisms (1994)

The relative biological effectiveness (RBE) of radiations as a function of linear energy transfer (LET) is analyzed for different types of damage causing reproductive death of mammalian cells. Survival curves are evaluated assuming a linear-quadratic dose dependence of the induction of reproductive death of cells. The linear term represents damage from single particle tracks and the quadratic term represents damage due to interaction of lesions from independent tracks. Differences and similarities are discussed of the LET dependence of single-track lethal damage, sublethal damage, potentially lethal damage and DNA double-strand breaks. The RBE-LET relationships are correlated with local energy deposition in small regions of the cells. The analysis shows that single-track lethal damage is composed in part of a type of damage that is not repaired by delayed plating and is very strongly dependent on LET with maximum RBE values up to 20, while another component consists of potentially lethal damage that is weakly dependent on LET with maximum RBE values less than 3. Potentially lethal damage and sublethal damage depend similarly on LET as DNA double-strand breaks. The sector of single-track damage which is not repaired by delayed plating is hypothesized to be caused through a repair-exchange mechanism involving two double-strand breaks induced close together. The identification of these different components of damage leads to an interpretation of differences in radiosensitivity and in RBE-LET relationships among various types of cells.
Robust and Reliable Portfolio Optimization Formulation of a Chance Constrained Problem (2017)

Abstract We solve a linear chance constrained portfolio optimization problem using Robust Optimization (RO) method wherein financial script/asset loss return distributions are considered as extreme valued. The objective function is a convex combination of portfolio’s CVaR and expected value of loss return, subject to a set of randomly perturbed chance constraints with specified probability values. The robust deterministic counterpart of the model takes the form of Second Order Cone Programming (SOCP) problem. Results from extensive simulation runs show the efficacy of our proposed models, as it helps the investor to (i) utilize extensive simulation studies to draw insights into the effect of randomness in portfolio decision making process, (ii) incorporate different risk appetite scenarios to find the optimal solutions for the financial portfolio allocation problem and (iii) compare the risk and return profiles of the investments made in both deterministic as well as in uncertain and highly volatile financial markets.
A face recognition system using fuzzy logic and artificial neural network (2003)

The authors have developed a method to extract a feature vector that is very important to recognizing facial images. The eye blinking method was used to get the location of the eyes roughly. Then a feature vector was obtained using locations and distances between feature points, that is the eyes, the nose, the mouth and the outline of the face. To make the feature vector invariant to the size of the facial image, it was normalized. Fuzzy linguistic variables were used instead of real numbers to represent the approximate distance between feature points. These fuzzified feature vectors were learned by an artificial neural network and used to recognize a facial image in the recognition phase. The face recognizer could recognize all learned persons correctly in spite of variations.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
<u>Correction</u> to "A Formal Basis for the Heuristic Determination of Minimum Cost Paths" (1972)

Our paper on the use of heuristic information in graph searching defined a path-finding algorithm, A*, and proved that it had two important properties. In the notation of the paper, we proved that if the heuristic function ñ (n) is a lower bound on the true minimal cost from node n to a goal node, then A* is <u>admissible;</u> i.e., it would find a minimal cost path if any path to a goal node existed. Further, we proved that if the heuristic function also satisfied something called the <u>consistency assumption,</u> then A* was <u>optimal;</u> i.e., it expanded no more nodes than any other admissible algorithm A no more informed than A*. These results were summarized in a book by one of us.
3D Printing in Concrete Materials and its Applications (2018)

<strong>Abstract: </strong>In recent decades, there has been growing strides in construction industry for using 3D printing in concrete. 3D printing in construction can be referred to various printing technologies used to fabricate architectural or construction components. While the use of 3D printing in concrete is still at an early stage, efforts to adapt the latest 3D printing technologies are being made worldwide, albeit slowly and cautiously, through numerous projects led by industry, government agencies, as well as academia. A number of different techniques and approaches have been attempted including on-site and off-site fabrication of construction components utilizing industrial robots, gantry systems and tethered autonomous vehicles. This paper presents recent trends and some of research and development efforts in 3D concrete printing including its applications in extraterrestrial environment. <strong>Paper Download URL (Source):</strong> <strong>https://www.researchpublish.com/papers/3d-printing-in-concrete-materials-and-its-applications</strong>
Site-Directed Mutagenesis Using a Double-Stranded DNA Template (2003)

It is now technically possible to create almost any desired mutation in a given DNA sequence. So called site-directed mutagenesis allows the introduction of designed mutations into specific locations. This approach is invaluable for studying gene regulation as well as for functional assessment of proteins and their interactions. Several protocols have been successfully employed to generate such mutants. Here I describe a “linker-scanning” method that I have used to systematically mutate the murine Major Histocompatibility Complex (MHC) class II Eα gene promotor (Fig. 1, ref. 1).
Leaf Essential Oil of Two Chemotypes of <i>Eucalyptus cloeziana</i> F. Muell. (1990)

ABSTRACT Two chemotypes ofEucalyptus cloeziana have been detected. The leaf essential oil of one contains mostly α-pinene, with small amounts of other monoterpenes and approximately 10% of sesquiterpenes. The second chemotype contains the β-triketone tasmanone, 4,6,6-trimethyl-5-methoxy-2-isobutanoyl-cyclohex-4-en-l,3-dione (96%) as its principal component. Some taxonomic implications for E. cloeziana and associated species groups within Eucalyptus are discussed.
Recent advances in hyperinsulinism and the pathogenesis of diabetes mellitus (1990)

Erasmus University, University Hospital, and Sophia Children's Hospital, Rotterdam, the Netherlands
Preface (2001)

This book analyses the evolution of Latin American and Caribbean labour markets in the 1990s and the impact of the economic reforms on them. The research on which it is based was part of a project on “Growth, Employment and Equity: The Impact of the Economic Reforms in Latin America and the Caribbean”, which was carried out by ECLAC and researchers from nine countries. The project studied how the reforms affected a series of economic and social variables (namely, those mentioned in the project’s title, as well as investment and technological change).
The functional effects of mutations Thr<sup>673</sup>→ Asp and Ser<sup>702</sup>→ Asp at the Pro‐directed kinase phosophorylation sites in the C‐terminus of chicken gizzard caldesmon (1993)

We expressed the C-terminal 99 amino acids of chicken gizzard caldesmon (658C) and two point mutants in which the preferred phosphorylation sites of MAP kinase and p34cdc2 kinase, Ser702 and Thr673 were altered to aspartic acid. The T673D mutant was indistinguishable from 658C but S702D was not phosphorylated by MAP kinase, was significantly less potent as an inhibitor of actin-tropomyosin activation of myosin MgATPase, and bound less actin-tropomyosin at low concentrations. Thus Ser702 is involved in the tropomyosin-dependent inhibitory mechanism of caldesmon, and its phosphorylation by MAP kinase or p34cdc2 kinase could modulate caldesmon function.
Historical Development of Asphalt Content Determination by the Ignition Method (1996)

This study was conducted to develop a reliable, detailed test procedure for determining asphalt cement (AC) content by the ignition method. The goal was to minimize the overall test time as well as technician time, and to produce a test method with acceptable accuracy. A detailed test procedure for the ignition method was developed based upon previous laboratory studies at the National Center for Asphalt Technology. Using the developed test procedure, an extensive evaluation of the ignition method was performed in the laboratory on mixtures with differing mixture properties (i.e. aggregate type, gradation, and AC content). The purpose of the laboratory investigations was to determine the accuracy of this test method for AC content and gradation determinations. The ignition method, centrifuge extraction method, and nuclear asphalt content (NAC) gauge were evaluated on five construction projects within the state of Alabama. The test procedure was modified based on this study to improve the accuracy and to reduce test time.
