Measurement/prediction comparison for K/sub u/-band MMIC active phased array for satellite communications

A 64-element experimental model for an active phased array has been built, with the active transmit modules implemented in MMIC (monolithic microwave integrated circuit) technology. A block diagram of the main components in the array system is presented. The transmit modules, which consist of 5-bit phase shifters, single-stage buffer amplifiers, 5-bit attenuators, and three-stage driver amplifiers were selected within predetermined performance bounds in order to satisfy the overall deviation limits allowed by the design. The authors present the measured results of the experimental model, which generated a number of shaped beams, as well as a number of scanned spot beams, within the global coverage area. Measured results for an array built to cover INTELSAT's AOR (Atlantic Ocean Region) show good agreement with predictions, which take into account implementation margins that allow for amplitude and phase perturbations. <<ETX>>
Is stem design important in uncemented total hip replacement to decrease subsidence in obese patients

There has been a world-wide trend towards cementless total hip replacement (THR) over the last 20 years (1). One of the primary reasons for the introduction of the cementless stem was to improve the outcome in younger, more active patients, particularly males. The New Zealand Joint Registry (NZJR) has shown a revision rate of 0.89/100 component years (cy) for cementless THR’s in patients under 55 years compared to 1.73/100 cy for cemented THR and 0.90/100 cy compared to 0.98/100 cy for those between 55–65 years (P<0.001). Over 65 years this is reversed with the cemented THR surviving significantly longer than the cementless variety (2).
Insulin Treatment Directly Restores Neutrophil Phagocytosis and Bactericidal Activity in Diabetic Mice and Thereby Improves Surgical Site Staphylococcus aureus Infection

ABSTRACT Bacterial infections, including surgical site infections (SSI), are a common and serious complication of diabetes. Staphylococcus aureus, which is eliminated mainly by neutrophils, is a major cause of SSI in diabetic patients. However, the precise mechanisms by which diabetes predisposes to staphylococcal infection are not fully elucidated. The effect of insulin on this infection is also not well understood. We therefore investigated the effect of insulin treatment on SSI and neutrophil function in diabetic mice. S. aureus was inoculated into the abdominal muscle in diabetic db/db and high-fat-diet (HFD)-fed mice with or without insulin treatment. Although the diabetic db/db mice developed SSI, insulin treatment ameliorated the infection. db/db mice had neutrophil dysfunction, such as decreased phagocytosis, superoxide production, and killing activity of S. aureus; however, insulin treatment restored these functions. Ex vivo treatment (coincubation) of neutrophils with insulin and euglycemic control by phlorizin suggest that insulin may directly activate neutrophil phagocytic and bactericidal activity independently of its euglycemic effect. However, insulin may indirectly restore superoxide production by neutrophils through its euglycemic effect. HFD-fed mice with mild hyperglycemia also developed more severe SSI by S. aureus than control mice and had impaired neutrophil phagocytic and bactericidal activity, which was improved by insulin treatment. Unlike db/db mice, in HFD mice, superoxide production was increased in neutrophils and subsequently suppressed by insulin treatment. Glycemic control by insulin also normalized the neutrophil superoxide-producing capability in HFD mice. Thus, insulin may restore neutrophil phagocytosis and bactericidal activity, thereby ameliorating SSI.
Upper level ontology and integration assessment modeling in digital watershed

With urbanization and environmental changes, water resources safety such as flood risk and drought have been faced with more challenges than ever before. Integrated assessment and modeling methods provided an effective resolution approach for this problem. However, different geographic data sources and modeling methods have produced barriers for sharing, integration, and communication in integrated assessment modeling. Ontology as a formalized description of domain knowledge provided the sharing conception and terms for watershed assessment and modeling. This paper first discusses ontology in digital watershed modeling. An ontology framework of digital watershed is given based on earth and environmental terminology ontologies (SWEET) and Web ontology language (OWL) representation. Then, the ontologies for integrated watershed flood risk assessment were designed. Ontology-guided watershed flood risk assessment workflow was developed, including cause factor and feature selection, criteria definition, and indicator assessment. Based on digital watershed ontology, entity data schema and field data schema were derived. Finally, an integrated assessment framework of digital watershed was developed, including data sources and GIS tools, watershed integrated assessment ontologies, integrated assessment fusion methods, and assessment database.
Activity profile and physical demands of football referees and assistant referees in international games

Abstract Time-motion analyses and physiological measurements were performed to investigate the physiological demands of football referees (n = 15) and assistant referees (n = 15) in international games and to examine whether high-intensity running (HIR) correlates to the referees' ability to keep up with play. Total distance covered (10.27 ± 0.90 vs. 6.76 ± 0.83 km) and HIR (1.92 ± 0.58 vs. 0.97 ± 0.22 km) was higher (P < 0.05) for referees than assistant referees, while sprinting distance was not different. Referees covered 0.89 ± 0.37 km by backwards running and assistant referees covered 1.54 ± 0.66 km by sideways running. Mean heart rate was higher (P < 0.05) for referees than assistant referees (150 ± 3 vs. 123 ± 3 b.p.m.), whereas blood lactate was not different. Backwards/sideways running decreased (P < 0.05) from the first to the last 15-min period for referees (49%) and assistant referees (42%), whereas HIR was unaltered. HIR was inversely correlated with the five highest distances from infringements in both halves (r = −0.60 and −0.58, P < 0.05). In conclusion, international match officials carry out an important amount of HIR throughout games, while low-intensity and unorthodox running activities are reduced during games. Referees performing the most high-intensity work are better to keep up with play. The match activities differ significantly between referees and assistant referees, which should be considered in training and testing procedures.

Crimen y castigo en Argentina: un enfoque empírico

El presente trabajo estima el modelo econnometrico del crimen utilizando como datos los delitos contra la propiedad cometidos en la veinticuatro provincias argentinas durante los anos 1982, 1985, 1988, 1991 y 1994. La razon de usar delitos contra la propiedad es dual: por un lado son delitos que a priori deberian ajustarse mejor a la logica del modelo economico del crimen ya que responden a un analisis racional de costo beneficio, y por otro lado usar datos por tipo de crimen y no agregados ayuda a eliminar dos sesgos importantes en este tipo de modelos: el sesgo originado por la diferencia en la tasa de denuncia y el originado por la diferencia en la tasa de culpabilidad de los diferentes delitos. En la medida en que las diferencias en tasas de denuncia y culpabilidad no varien geograficamente o con el tiempo, un modelo de efectos fijos podria solucionar el problema pero ello implicaria un supuesto demasiado fuerte. Un modelo con datos por tipo de crimen ayuda a eliminar ese sesgo potencial. Ademas se eliminan otros dos sesgos importantes: los producidos cuando se estudia el impacto disuasivo diferencial entre el arresto y la condena ceteris paribus que toma las tasas de condena y de encarcelamiento constantes. Esto implicaria asumir que al aumentar los arrestos los jueces condenan a una tasa constante lo cual sesgaria hacia arriba el impacto marginal del arresto. Similarmente ocurre con las condenas y las condenas efectivas. Los resultados confirman las predicciones del modelo economico del crimen y se demuestra que luego de eliminar los sesgos la diferencia entre los efectos disuasivos del arresto y de la condena desaparecen.

Tension Pneumothorax Due to Intrapulmonary Placement of Intercostal Chest Drain

Insertion of an intercostal chest drain in patients with chest trauma can be followed by several serious and even life-threatening complications! Confirmation of correct position can be difficult, especially in critically ill patients. We report a case of a patient with chest trauma who developed a tension pneumothorax despite the presence of an intercostal chest drain and in whom plain X-rays failed to diagnose malposition of two intercostal chest drains.
The Molecular Basis of Differential Subcellular Localization of C2 Domains of Protein Kinase C-α and Group IVa Cytosolic Phospholipase A2 *

The C2 domain is a Ca2+-dependent membrane-targeting module found in many cellular proteins involved in signal transduction or membrane trafficking. C2 domains are unique among membrane targeting domains in that they show a wide range of lipid selectivity for the major components of cell membranes, including phosphatidylserine and phosphatidylcholine. To understand how C2 domains show diverse lipid selectivity and how this functional diversity affects their subcellular targeting behaviors, we measured the binding of the C2 domains of group IVa cytosolic phospholipase A2 (cPLA2) and protein kinase C-α (PKC-α) to vesicles that model cell membranes they are targeted to, and we monitored their subcellular targeting in living cells. The surface plasmon resonance analysis indicates that the PKC-α C2 domain strongly prefers the cytoplasmic plasma membrane mimic to the nuclear membrane mimic due to high phosphatidylserine content in the former and that Asn189 plays a key role in this specificity. In contrast, the cPLA2 C2 domain has specificity for the nuclear membrane mimic over the cytoplasmic plasma membrane mimic due to high phosphatidylcholine content in the former and aromatic and hydrophobic residues in the calcium binding loops of the cPLA2 C2 domain are important for its lipid specificity. The subcellular localization of enhanced green fluorescent protein-tagged C2 domains and mutants transfected into HEK293 cells showed that the subcellular localization of the C2 domains is consistent with their lipid specificity and could be tailored by altering their in vitro lipid specificity. The relative cell membrane translocation rate of selected C2 domains was also consistent with their relative affinity for model membranes. Together, these results suggest that biophysical principles that govern thein vitro membrane binding of C2 domains can account for most of their subcellular targeting properties.
An equivalent circuit model for multi-port networks

This paper suggests an equivalent circuit model and extraction method for the equivalent circuit elements using Y-parameter of multi-port networks. A coupled line directional coupler is selected as the example for verification of the suggested technique. The accuracy of the extracted equivalent circuit is evaluated by comparing the S-parameters obtained from EM simulation data to circuit simulation results.
The truth, the whole truth and nothing but the truth

In this paper we study a class of problems where society wants to elicit the truth from the agents. We focused our attention on a canonical subproblem in which the basic question is tractable. We prove the impossibility to obtain the truth from dominant strategies and that implementation in Nash and Coalition-Proof can be done with simple mechanisms
Concentration-dependent internalization of a cytokine/cytokine receptor complex in human hematopoietic cells.

Soluble steel factor (SF) is a potent stimulator of hematopoietic progenitor cell proliferation in vitro, and cytokine combinations that include SF can support extensive expansions of hematopoietic cells. Recently, we showed that very primitive progenitor cells from normal human bone marrow require exposure to very high concentrations of cytokines to maintain their primitive status while proliferating. These cells also display higher cell-specific cytokine uptake rates than more differentiated types of hematopoietic cells. As a first step toward identifying the mechanisms involved in mediating such cytokine dose-dependent effects, we have now investigated the kinetics of SF receptor (c-kit) internalization by human Mo7e cells exposed to different extracellular concentrations of soluble SF. Transfer of Mo7e cells to a higher concentration of SF caused an initially rapid downregulation of cell surface c-kit which was accompanied by a rapid depletion of extracellular SF. Confocal microscopy showed a concomitant increase in the number and intensity of intracellular c-kit aggregates. After the first 30 min, the cells continued to deplete SF from the medium but at a much slower rate. During this period, there was a gradual recovery of expression of c-kit on the cell surface. A mathematical analysis of bulk medium to cell-surface SF-mass transport indicated that the cytokine-depletion rates measured were not likely to have significantly depleted the SF concentration in the microenvironment of the cells. Taken together, these results underscore the importance of monitoring and appropriately regulating cytokine concentrations in hematopoietic cell expansion cultures. They may also help to explain the different biological responses exhibited by primitive hematopoietic cells exposed to different types and concentrations of cytokines for periods of days.
P300 Chinese input system based on Bayesian LDA

Abstract A brain-computer interface (BCI) is a new communication channel between humans and computers that translates brain activity into recognizable command and control signals. Attended events can evoke P300 potentials in the electroencephalogram. Hence, the P300 has been used in BCI systems to spell, control cursors or robotic devices, and other tasks. This paper introduces a novel P300 BCI to communicate Chinese characters. To improve classification accuracy, an optimization algorithm (particle swarm optimization, PSO) is used for channel selection (i.e., identifying the best electrode configuration). The effects of different electrode configurations on classification accuracy were tested by Bayesian linear discriminant analysis offline. The offline results from 11 subjects show that this new P300 BCI can effectively communicate Chinese characters and that the features extracted from the electrodes obtained by PSO yield good performance.
Types de textes ou genres de discours ? Comment classer les textes qui disent de et comment faire?

Many genres of discourse offer instructional and procedural semantic and pragmatic features which are expressed by common linguistic forms. Considering such regularities, one may be induced to treat them as a category or a type of text. As the article presents some of the common characteristics shared by recipes, assembly instructions, topographical guides, horoscopes and the tip columns that can be found in magazines, it shows that those permanent features are directly generated by the genres. Therefore they fall within the field of discourse analysis and not within that of a text grammar or a text typology.
Fabrication of Advanced Functional Devices Combining Soft Chemistry with X‐ray Lithography in One Step

Deep X-ray lithography combined with sol-gel techniques offers facile fabrication of controlled patterned films. Using sol-gel, different functional properties can be induced; deep X-ray lithography alters the functionality in the exposed regions. Miniaturized devices based on local property changes are easily fabricated: this technique requires no resist, enabling direct patterning of films in a one-step lithographic process.
A new mathematical approach for input-output pairing in MIMO square systems

This paper presents a new mathematical method to determine the control configuration for n × n multi-input-multi-output (MIMO) processes. Previously the Relative Gain Array (RGA) was employed as a classical way to determine the pairing between inputs and outputs which may not suggest the best pairing in cases where the systems are larger than 2×2. The new strategy gives suitable pairing recommendations and is easy to interpret based on this theory that each output with one of the inputs is easier to be controlled. Some options like tracking targets based on desired frequencies are considered in this method. Comparisons with RGA method demonstrate the effectiveness of this methodology, through the use of several examples.
Development of Ontologies with Minimal Set of Conceptual Relations

In the paper we describe our approach to development of ontologies with small number of relation types. Non-taxonomic relations in our ontologies are based on ontological dependence conception described in the formal ontology. This minimal relations set does not depend on a domain or a task and makes possible to begin the ontology construction at once, as soon as a task is set and a domain is determined, to receive the first version of an ontology in short time. Such an initial ontology can be used for information-retrieval applications and can serve as a structural basis for further development of the ontology
A framework for context-sensitive metadata description

Expectations regarding the new generation of Web depend on the success of Semantic Web technology. Resource Description Framework (RDF) is a basis for explicit and machine-readable representation of semantics. However RDF is not suitable for describing dynamic and context-sensitive resources (eg. processes). We present the Context Description Framework (CDF) as an extension of the RDF by adding a 'TrueInContext' component to the basic RDF triple ('subject-predicate-object'), and consider contextual value as a container of RDF statements. We also add a probabilistic component, which allows multilevel contextual dependence descriptions as well as presumes possibility for Bayesian reasoning with the RDF model.
Betty Joseph 1917–2013

Betty Joseph, who died aged 96 on 4 April 2013, was a member of the British Society, a Sigourney Prize winner, an internationally acclaimed teacher and supervisor and one of the most outstanding contributors to clinical psychoanalysis, ever. Joseph’s main written contributions were gathered together with the help of Michael Feldman and Elizabeth Spillius in her Psychic Equilibrium and Psychic Change (Joseph, 1989), published in the New Library of Psychoanalysis. Central to her thinking, teaching and practice was her work on transference and countertransference, approached through the lens of attending to the fine details of the psychoanalytic session and the analyst’s and patient’s contributions to it. To set out her contribution as clearly as I can I will use her paper Transference: The total situation as illustrative of my view of her seminal contribution. The paper was presented at a scientific symposium of the British Society in December 1983 and then published in this Journal in 1985 (Joseph, 1985). It starts with characteristic Joseph phrasing – familiar not just to colleagues in clinical and scientific discourse but also to friends and relatives when making social arrangements with her. She states her intention to discuss “how we are using the concept of transference in our clinical work today” (italics added). Her use of “we” in this passage expressing, on the one hand, her genuine modesty and location of herself within a team of contributors, while at the same time definitely containing a hint of the royal prerogative and her ambiguous self-deprecating wit. It was always fun as well as inspiring and a privilege to be with her and to work with her in just such a spirit. The fact is that, while it is quite possible to place Joseph’s way of thinking about transference and countertransference inside a long line of contributions from Freud to Klein, Bion, Heimann and beyond, as she did herself, my experience of the way she used these core concepts and made them her own makes me think they were foundational. At some point increments become a paradigm change and I think her contributions along with those by Bion mark such movement. Anyone who had the chance to discuss their clinical efforts with her over any kind of extended period, as I was lucky enough to do, came to appreciate the central concepts afresh. Her core idea about the clinical situation and the role of transference–countertransference within it appears early in the paper I have chosen to discuss:

Composite adaptive control of constrained robots

Force control is the main challenge in force/motion control of constrained robots. This paper presents a composite adaptive controller to deal with the force error. The proposed controller is designed and analyzed in two steps. In the first step, the force error is shown to be asymptotically proportional to the residual force. A force feedback signal is introduced to reduce the force error. The second step presents an analytical study on a composite adaptive controller with a focus on the convergence of the residual force. It is proven that the proposed adaptive controller is able to achieve zero tracking and force errors without the persistent excitations.
