Finite phased arrays of rectangular microstrip patches (1986)

Finite phased arrays of rectangular microstrip patch antennas are analyzed. Reflection coefficient magnitudes, element patterns and efficiency (based on power lost to surface waves) are calculated for various sized arrays on substrates of practical interest and are compared with previous infinite array solutions. Measured element patterns and mutual coupling data for a small array are presented and compared with calculations.
Ensemble Neural Network Approach for Accurate Load Forecasting in a Power System (2009)

Ensemble Neural Network Approach for Accurate Load Forecasting in a Power System The paper presents an improved method for 1-24 hours load forecasting in the power system, integrating and combining different neural forecasting results by an ensemble system. We will integrate the results of partial predictions made by three solutions, out of which one relies on a multilayer perceptron and two others on self-organizing networks of the competitive type. As the expert system we will apply different integration methods: simple averaging, SVD based weighted averaging, principal component analysis and blind source separation. The results of numerical experiments, concerning forecasting the hourly load for the next 24 hours of the Polish power system, will be presented and discussed. We will compare the performance of different ensemble methods on the basis of the mean absolute percentage error, mean squared error and maximum percentage error. They show a significant improvement of the proposed ensemble method in comparison to the individual results of prediction. The comparison of our work with the results of other papers for the same data proves the superiority of our approach.
Understanding Linear Programming Modeling Through an Examination of the Early Papers on Model Formulation (1997)

We use the models of cognitive psychology and the early literature on linear programming models to understand how experts organize their thinking about models. We show that several different patterns appear in the way models are related to each other. This paper also is a kind of cognitive history of the formulation of linear programming models in the first decade after the invention of the field.
A Study of HRD Concepts, Structure of HRD Departments, and HRD Practices in India (2001)

A number of human resources development frameworks has come into existence in the last ten years from various parts of the world. Indian organizations have begun to use these for improving their HRD systems and their impact. An Integrated HRD Systems Approach was evolved for Indian organizations at the Indian Institute of Management, Ahmedabad by Udai Pareek and T V Rao for L&T. This paper examines the current status of structuring of the HRD function and HRD subsystems in India against this “Integrated HRD Systems” framework. The paper also comments on the recent approaches to HRD. Data from HRD audits of 12 Indian organizations indicated that HRD function is not well structured, is inadequately differentiated, poorly staffed, and fails to meet the requirements of this framework. In the light of these experiences of Indian organizations in implementing this framework, the paper points out the prerequisites for success of other HRD frameworks in India.
Contrasting Approaches in Marital Counseling (1967)

My Aim in this paper is to look at the therapist‐marital couple relationship as a social system, and from this perspective to outline some aspects of the difference between treating a husband or wife as an individual patient and treating them together as a marital couple. I will try to differentiate individual treatment and treatment of the marital pair on two dimensions: their respective use as sources of data about the marital relationship, for both therapy and research, and their potentialities for changing the marital interaction.

Never-Smokers With Lung Cancer: Epidemiologic Evidence of a Distinct Disease Entity (2006)

Never-smokers comprised a high proportion of NSCLC patients in Singapore. Definite epidemiologic differences exist between never-smokers and smokers. Differences in survival outcome further suggest that the biology underlying the pathogenesis and behavior of the disease may be different for never-smokers.
Parallel algorithms for mining frequent structural motifs in scientific data (2004)

Discovery of important substructures from molecules is an important data mining problem. The basic motivation is that the structure of a molecule has a role to play in its biochemical function. There is interest in finding important, often recurrent, substructures both within a single molecule and across a class of molecules.Recently, we have developed a general purpose suite of algorithms -- the MotifMiner Toolkit -- that can mine for structural motifs in a wide area of biomolecular datasets. While the algorithms have proven to be extremely useful in their ability to identify novel substructures, the algorithms themselves are quite time consuming. There are two reasons for this: i) inherently the algorithm suffers from the curse of subgraph isomorphism; and ii) handling noise effects (e.g. protein structure data) results in a significant slowdown.To address this problem in this paper we propose parallelization strategies in a cluster environment for the above algorithms. We identify key optimizations that handle load imbalance, scheduling, and communication overheads. Results show that the optimizations are quite effective and that we are able to obtain good speedup on moderate sized clusters.
Arsenic Inhibits Myogenic Differentiation and Muscle Regeneration (2010)

Our results suggest that As2O3 inhibits myogenic differentiation by inhibiting Akt-regulated signaling.
Listening to your inner voices (2006)

Our research investigates notification qualities of different types of voices, moving toward interfaces that support optimal allocation of attention to maximize system utility. We conducted an experiment to determine the interruption, reaction, and comprehension values of three different voice categories: the user's voice, a familiar voice, and an unfamiliar voice. Initial testing showed significant and impactful results: unfamiliar voices are the least interruptive, and a user reacts most quickly to one's own voice. Motivated by these findings, we report on the development and deployment of a notification system that exploits the differences in familiarity of a voice.
Software internationalisation and localisation: practice and evolution (2002)

Programming continues to be an increasingly complex task. Developing new software and re-engineering existing software for the international market adds further complexity to the process. A better understanding of software internationalisation and localisation approaches helps managers to supervise development teams more efficiently and effectively. Such an understanding will also help programmers to be more productive by developing software in standard ways that provide the necessary flexibility. This paper proposes a classification of approaches to software internationalisation and localisation. It summarises them as an evolutionary sequence, ranging from the early localisation-only approach up to the current internationalisation-before-localisation approaches. It is suggested that managers and programmers should be aware of these approaches to define and regulate their development processes in a way that facilitates current and fttture internationalisation and localisation requirements.
Unification of Reaction Metrics for Green Chemistry:  Applications to Reaction Analysis (2005)

A formalism is presented which unifies key reaction metrics associated with “greenness” in chemical reactions with respect to raw materials usage. The fundamental basis of this treatment begins with balanced chemical reactions in which byproducts are identified. The primary or kernel metrics are reaction yield, scale of reaction, stoichiometric factor (SF), and Trost's atom economy (AE). The stoichiometric factor is a new metric that is defined to account for reactions run under nonstoichiometric conditions, that is, with one or more reagents in excess. A general relation for reaction mass efficiency (RME) is derived which shows that this metric is a composite of the aforementioned primary metrics and takes into account solvent usage in the reaction and postreaction phases (workup and purification). The Sheldon environmental impact factor E is treated at various levels of complexity according to what is constituted as waste and is shown to be related to RME by a simple inverse expression. A flowchart is presented which shows other simple relationships connecting all metrics. Raw material costs, optimum conditions for recycling or reclaiming catalysts and reaction and postreaction solvents, and the handling of reactions giving isomeric products are also assessed. General algorithms are proposed for determining kernel reaction metrics for linear and convergent sequences that can be used to compare the intrinsic, or best-case scenario, green performances of synthetic plans to a common target structure. All key relationships can be implemented in a spreadsheet format from which reaction histograms or “maps” can be generated. Individual reaction RME performances can be gauged, ranked, and decomposed according to AE, SF, and reaction yield kernel metrics. This allows for the easy identification of best and worst reactions in a process or sequence. Example applications of the present methodology include the following: (a) a comparative analysis of the synthesis of quinine by the classic Woodward−Rabe and the modern greener Stork methods; (b) the analysis of the industrial synthesis of sildenafil (Viagra) by a convergent strategy; and (c) the analysis of kinetic resolution of racemic alcohols by a successive oxidation and recycling reduction cycle.

Immunobiology of Asthma (2009)

Asthma is characterized by chronic inflammation of the airways in which there is an overabundance of eosinophils, mast cells, and activated T helper lymphocytes. These inflammatory cells release mediators that then trigger bronchoconstriction, mucus secretion, and remodeling. The inflammatory mediators that drive this process include cytokines, chemokines, growth factors, lipid mediators, immunoglobulins, and histamine. The inflammation in allergic asthma can be difficult to control. This is mainly due to the development of an adaptive immunity to an allergen, leading to immunological memory. This leads to recall reactions to the allergen, causing persistent inflammation and damage to the airways. Generally, in asthma inflammation is directed by Th2 cytokines, which can act by positive feedback mechanisms to promote the production of more inflammatory mediators including other cytokines and chemokines. This review discusses the role of cytokines and chemokines in the immunobiology of asthma and attempts to relate their expression to morphological and functional abnormalities in the lungs of asthmatic subjects. We also discuss new concepts in asthma immunology, in particular the role of cytokines in airway remodeling and the interaction between cytokines and infection.
The generation of high precision aspherical surfaces in glass by CNC machining (1981)

The design and production of an f/1 aspheric focusing lens for a high-power laser system operating at 1054 nm is described. The relevant lens design parameters and the degree of flexibility in their choice are described and these, when carefully chosen, result in an extremely versatile lens with a large wavelength cover. The manufacture of the lens is also simplified. A comparison is made between the production of an aspheric surface by high quality conventional optical manufacturing processes and one generated and polished by a CNC jig grinding machine.
Enhanced scanning range of coupled oscillator arrays utilizing frequency multipliers (2002)

Scanning in arrays is conventionally achieved through phase shifters. Recent work has indicated that scanning can be achieved with significantly reduced complexity and cost using coupled-oscillator techniques. However, the scan range has been somewhat limited using this technique. This paper describes a simple method to greatly enhance the scan range using varactor frequency doublers, which has the added advantage of simplifying the fundamental mode oscillator design. Beam scanning in antenna arrays without the use of phase shifters is theoretically and experimentally verified. The array design frequency is chosen as 8 GHz, and the fundamental mode oscillators are designed for 4 GHz.
Restoration of Abduction in the Paralyzed Canine Vocal Cord (1973)

Abductive ability was restored in unilaterally paralyzed canine larynges by means of a modification of the nerve-muscle pedicle technique of Tucker et al, utilizing the motor branch to the sternohyoid muscle. Excellent abduction was achieved both with spontaneous respiration and with electrical stimulation of the implanted motor nerve. This technique might be applied clinically to avoid the need for arytenoid mobilization in patients suffering from bilateral vocal cord paralysis, thus, preserving voice function.
Efficient computer design of compact planar band-pass filters using electrically short multiple coupled lines (2003)

The design of high performance, compact, planar band-pass filters using large numbers of coupled, electrically short, microstrip transmission lines, with multiple non-nearest neighbor coupling, is presented. High order frequency dependent lumped elements are used to accurately represent the filter structure, including all intended or parasitic non-nearest neighbor coupling. While generally applicable, this technique is particularly useful for filters manufactured using thin film High Temperature Superconductors (HTS), where small size is required.
Fluorotyrosine M13 coat protein: fluorine-19 nuclear magnetic resonance study of the motional properties of an integral membrane protein in phospholipid vesicles (1978)

We have prepared in vivo a fluorotyrosyl derivative of M13 coat protein and have incorporated it at high levels in small phospholipid vesicles, using a urea-cholate dialysis procedure. 19F nuclear magnetic resonance experiments at 254 MHz with this system indicate a T1 of 0.32 s and line width of 300 Hz. The observed line width increases dramatically below the gel to liquid-crystalline transition temperature for the lipid, indicating that the probe is sensitive to the phase state of the bilayer. Neclear Overhauser enhancement and field dependence of line width were used to establish the relative contributions of dipolar interactions and chemical-shift anisotropy to the observed T1 and line width. From this relaxation data, we have constructeda model for the motional properties of the protein in the lipid bilayer. This model is characterized by correlation times for rotation about the alphabeta and betagamma bonds of the two tyrosyl residues of 2 x 10(-8) and k x 10(-9) s, respectively. Rapid intermolecular dipole-dipole interactions are required to account for theestimated dipolar contribution to T1. A reasonable model for these interactions is that lipid methylene protons are involved in relaxation of the fluorine probes (which reside in the hydrophobic region of this integral membrane protein). We estimate a minimum translational diffusion coefficient for such lipids of D greater than 3 x 10(-9) cm2/s.
Differential label‐free quantitative proteomic analysis of avian eggshell matrix and uterine fluid proteins associated with eggshell mechanical property (2013)

Eggshell strength is a crucial economic trait for table egg production. During the process of eggshell formation, uncalcified eggs are bathed in uterine fluid that plays regulatory roles in eggshell calcification. In this study, a label-free MS-based protein quantification technology was used to detect differences in protein abundance between eggshell matrix from strong and weak eggs (shell matrix protein from strong eggshells and shell matrix protein from weak eggshells) and between the corresponding uterine fluids bathing strong and weak eggs (uterine fluid bathing strong eggs and uterine fluid bathing weak eggs) in a chicken population. Here, we reported the first global proteomic analysis of uterine fluid. A total of 577 and 466 proteins were identified in uterine fluid and eggshell matrix, respectively. Of 447 identified proteins in uterine fluid bathing strong eggs, up to 357 (80%) proteins were in common with proteins in uterine fluid bathing weak eggs. Similarly, up to 83% (328/396) of the proteins in shell matrix protein from strong eggshells were in common with the proteins in shell matrix protein from weak eggshells. The large amount of common proteins indicated that the difference in protein abundance should play essential roles in influencing eggshell strength. Ultimately, 15 proteins mainly relating to eggshell matrix specific proteins, calcium binding and transportation, protein folding and sorting, bone development or diseases, and thyroid hormone activity were considered to have closer association with the formation of strong eggshell.

The in vitro antioxidant activity of different types of palm dates (Phoenix dactylifera) syrups (2010)

Palm date fruits have been used for nutritional and medicinal purposes in Middle Eastern countries. They are used in folk medicine for treatment of liver diseases and highly recommended to be consumed by pregnant women before and after delivery. Therefore, the present work aimed to determine the total phenolic content and total flavonoids in three syrups obtained from palm dates extracted with aqueous ethanol (80%) and to evaluate in vitro their antioxidative properties. The new findings showed that the three tested syrups contained significantly different amounts of both total phenolic content and total flavonoids. Syrups can be arranged according to the increase of total phenolic contents and total flavonoids as follows: Yemeni-Rotab > Saudi-Tamr > Iraqi-Tamr. The results of antioxidant activities of palm dates syrups obtained by using different in vitro methods were varied depending on the method used. According to the TBARS method, H2O2 scavenging ability and DPPH methods, all syrups showed to have high to very high antioxidant activities. On the other hand, syrups showed low to intermediate antioxidant activities when other methods were used, such as the scavenging ability of OH and NO and the ability to chelate Fe2+ ions. Generally, the values of antioxidant activities of Rotab-syrup have been shown to be always the highest.
Parathyroid hormone induces sequential c-fos expression in bone cells in vivo: in situ localization of its receptor and c-fos messenger ribonucleic acids. (1994)

Localization of PTH/PTH-related peptide (PTH/PTHrP) receptor mRNA and PTH induction of c-fos expression were examined in bones of 4-week-old rats by in situ hybridization. Receptor transcripts were most highly expressed by growth plate chondrocytes from lower proliferating to upper hypertrophic cell layers. PTH/PTHrP receptor mRNA also was expressed in osteoblasts as well as in some bone marrow stromal cells. Subcutaneous administration of human PTH-(1-84) (225 micrograms/kg) induced rapid, transient, and sequential expression of the protooncogene c-fos mRNA in cells in bone. Osteoblasts and chondrocytes expressing PTH/PTHrP receptor transcripts as well as some stromal cells expressed c-fos mRNA first (15-60 min), followed by transient expression in the majority of stromal cells and in osteoclasts (1-2 h). Delayed and transient induction of c-fos in cells with few or no detectable receptor transcripts suggests that PTH acts indirectly on stromal cells and osteoclasts by either stimulating osteoblasts to secrete a substance(s) that acts locally and/or inducing changes in cell-cell contacts between osteoblasts and adjacent cells.
<i>BCL6</i> gene rearrangement and protein expression are associated with large cell presentation of extranodal marginal zone B‐cell lymphoma of mucosa‐associated lymphoid tissue (2010)

Extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) is an indolent B-cell lymphoma, which is often localized in the stomach. It is characterized by typical morphology, immunology, cytogenetics and expression profile. The coexistence of a large B-cell lymphoma and a MALT lymphoma in the gastrointestinal tract is defined as a composite lymphoma (ComL) and, as we have previously shown, is almost always the consequence of secondary transformation of MALT lymphoma. Here, we have analyzed a panel of seven MALT lymphomas, seven ComL and thirteen large cell variants of marginal zone B-cell lymphomas (MZBL) using FISH for the detection of rearrangements of IGH, MALT1, BCL6, BCL10 and FOXP1 and immunohistochemistry for Bcl6, Bcl10 and FoxP1. Translocations involving IGH were found in 10/27 lymphomas including two cases with IGH-BCL6 fusion and one with IGH-BCL10 fusion; in 7/10 cases, the translocation partner was not identified. Bcl10 and FoxP1 protein expression was heterogeneous throughout the series. Genetic rearrangements of BCL6 and Bcl6 protein expression were found almost exclusively in the large cell components of the ComL and the large cell extranodal MZBL (p = 0.2093 and p = 0.0261, respectively). These findings suggest Bcl6 as a marker for transformation of MALT lymphoma.
