SWITCHED-CAPACITOR FIR FILTERS. (1987)

The design of simple FIR filters with equally-spaced zeros on the z-domain unit circle is presented. The proposed circuits can be realized by stray-insensitive switched-capacitor (SC) techniques and are well suited to be combined with recursive SC filters to improve stopband attenuation and/or alleviate prefilter requirements. 4 refs.
Algorithm for M-FSK intrapulse radar signal analysis (2014)

Modern radar uses more and more complex waveforms. Some waveforms are developed intentionally to make their intercept almost impossible. The main distinctive features of radar signal are hidden in its intrapulse structure. The intrapulse modulation analysis of a detected signal is a major task of an ELINT/ESM system. As a result of measurement, for each pulse specific description, so called pulse descriptor word (PDW) or finger printing, containing primary parameters is created. To determine a PDW in case of M-ary Frequency Shift Keying intrapulse modulation (M-FSK intrapulse modulation) in the recent hardware implementation of electronic intelligence system receivers is hardly achieved. The algorithm for unknown radar signals with M-FSK intrapulse modulation by new approach in signal analysis is described. The proposed algorithm is performed on the base of Subspectral Decomposition Method (SDM). The SDM principle and results of modeling and simulation of M-FSK intrapulse modulation signal recognition and decomposition are presented.
Vascular calcification in chronic kidney disease (2010)

VC (vascular calcification) is highly prevalent in patients with CKD (chronic kidney disease), but its mechanism is multifactorial and incompletely understood. In addition to increased traditional risk factors, CKD patients also have a number of non-traditional cardiovascular risk factors, which may play a prominent role in the pathogenesis of arterial calcification, such as duration of dialysis and disorders of mineral metabolism. The transformation of vascular smooth muscle cells into chondrocytes or osteoblast-like cells seems to be a key element in VC pathogenesis, in the context of passive calcium and phosphate deposition due to abnormal bone metabolism and impaired renal excretion. The process may be favoured by the low levels of circulating and locally produced VC inhibitors. VC determines increased arterial stiffness, left ventricular hypertrophy, a decrease in coronary artery perfusion, myocardial ischaemia and increased cardiovascular morbidity and mortality. Although current therapeutic strategies focus on the correction of phosphate, calcium, parathyroid hormone or vitamin D, a better understanding of the mechanisms of abnormal tissue calcification may lead to development of new therapeutic agents, which could reduce VC and improve cardiovascular outcome in CKD patients. The present review summarizes the following aspects: (i) the pathophysiological mechanism responsible for VC and its promoters and inhibitors, (ii) the methods for detection of VC in patients with CKD, including evaluation of arterial stiffness, and (iii) the management of VC in CKD patients.
[Reversibility of visual field defects in primary open-angle glaucoma]. (1991)

The course of the glaucomatous visual field seems to be best followed by computerized perimetry which allows threshold evaluation in a great number of locations and statistical analysis of the results. To determine the visual field defect reversibility, 16 patients (27 eyes) affected by uncontrolled open-angle glaucoma underwent visual field analysis before and after prescription of a new medical therapy. To avoid the "learning effect" and to decrease the influence of the heterogeneous component of long-term fluctuation, the visual field examination was repeated within 48 hours whenever a change in sensitivity was detected. In addition a total of 10 normal eyes in 10 patients were tested as a control group. A statistically significant threshold improvement was demonstrable after one week of therapy in 31.7% of the eyes.
Development of children's understanding of length, area and volume measurement principles (2006)

This study investigated the concurrent development of children’s understanding of length, area, and volume measurement in Grades 1-4. From a 45-minute interview, an attempt was made to derive three parallel scores assessing understanding of each of five measurement principles: the need for congruent units, the importance of using an appropriate unit, the need to use the same unit when comparing objects, the relationship between the unit and the measure, and the structure of the unit iteration. Valid comparisons could only be made across three of these five principles. On the others, student scores increased with grade, with length preceding area and area preceding volume in most cases. The results have several implications for teachers. Measurement has long been regarded as an important component of numeracy (Cockcroft, 1982). It constitutes a separate strand in the official syllabuses of all Australian states and territories, and receives a similar emphasis in the US and the UK. The focus is on the measurement of the spatial attributes of length, area, and volume, and most concepts are expected to be mastered in primary school. School syllabuses frequently make statements about children’s measurement learning that are at least partly based on research. For example, the recently revised New South Wales mathematics syllabus outlines a developmental sequence for the early grades that includes the following statement of the basic principles of measurement: Students develop the key understandings of the measurement process using repeated informal units. These include: 1. the need for repeated units that do not change 2. the appropriateness of a selected unit 3. the need for the same unit to be used to compare two or more objects 4. the relationship between the size of the unit and the number required to measure, and 5. the structure of the repeated units. (Board of Studies NSW, 2002, p. 91) Most of the research on which such statements are based has investigated length, area, and volume measurement concepts separately. This paper describes an attempt to validate the development assumed in syllabus documents and in particular to relate children’s development of the three attributes.
Hypoglycaemic and hypotensive effects of Globimetula cupulata (DC) Van Tieghem (Loranthaceae) aqueous leaf extract in rats. (2007)

The leaves of some mistletoes, specifically Loranthus micranthus Linn, Tapinanthus dodoneifolius (DC) Danser and Globimetula cupulata (DC) Van Tieghem (family: Loranthaceae), are used traditionally in Nigerian folk medicine to manage, control and/or treat a plethora of human ailments, including diabetes mellitus and hypertension. In order to scientifically appraise some of the folkloric, ethnomedical uses of Globimetula species, the present study was undertaken to investigate the hypoglycaemic and hypotensive effects of Globimetula cupulata aqueous leaf extract (GCE, 50-800 mg/kg po) in rat experimental paradigms. The hypoglycaemic effect of the plant extract was examined in normal (normoglycaemic) and diabetic (hyperglycaemic) rats using a streptozotocin (STZ)-induced diabetes model. Normotensive Wistar and hypertensive Dahl salt-sensitive rats were used to investigate the hypotensive (antihypertensive) effect of the plant extract. Metformin (MFM, 500 mg/kg po) was used as the reference hypoglycaemic agent for comparison. Acute oral administrations of G cupulata aqueous leaf extract (GCE, 50-800 mg/kg po) caused dose-related, significant (p < 0.05-0.001) hypoglycaemia in normal and STZ-treated diabetic rats. Furthermore, acute intravenous administrations of GCE (50-800 mg/kg iv) produced dose-dependent, significant reductions (p < 0.05-0.001) in systemic arterial blood pressure and heart rates of the normotensive and hypertensive rats used. Although the exact hypoglycaemic and hypotensive mechanisms of action of the plant extract still remain speculative, it is unlikely that the extract induced hypotension in the mammalian experimental animal model via cholinergic mechanisms, since its cardiovascular effects were resistant to atropine pretreatment. However, the findings of this experimental study indicated that Globimetula cupulata aqueous leaf extract possesses hypoglycaemic and hypotensive properties. This therefore lends pharmacological support to the folkloric, ethnomedical uses of the plant in the management and/ or control of diabetes mellitus and hypertension among the Yoruba-speaking people of western Nigeria.

Solid‐state IR–LD spectroscopic and theoretical analysis of arginine‐containing peptides (2006)

Structural prediction and IR-characteristic bands assignment of arginine-containing tri- and tetrapeptides glycyl-glycyl-arginine (GGArg) and glycyl-glycyl-arginyl-alanine (GGArgAla) have been carried out, using linear-dichroic infrared (IR-LD) spectroscopy of oriented solid-samples in a nematic liquid crystal suspension. Spectroscopic data have been supported with ab initio analysis (Hartree-Fock level of theory and 6-31++G** basis set). Predicted geometry parameters have been compared with known crystallographic ones of similar peptides, indicating a good correlation.
Initial stages of SiC oxidation investigated by ion scattering and angle-resolved x-ray photoelectron spectroscopies (2001)

Initial stages of oxidation of single-crystal, Si-faced silicon carbide were investigated using ion scattering and angle-resolved x-ray photoelectron spectroscopies. The very first oxidation products are shown to be silicon oxycarbides (SiCxOy), while, for longer oxidation times, a mixture of SiCxOy and SiO2 is formed in the near-surface region of the growing oxide film. The composition of the near-surface region of such thin films is very similar to that reported in previous investigations for the near-interface region when thicker oxides films are grown on SiC.

Esculetin inhibits the inflammatory response by inducing heme oxygenase-1 in cocultured macrophages and adipocytes (2014)

Obesity is associated with chronic low-grade inflammation of adipose tissue. In this study, we investigated the anti-inflammatory effects of esculetin (ECT) through up-regulation of heme oxygenase-1 (HO-1) in cocultured macrophages and adipocytes. RAW264.7 macrophages and differentiated 3T3-L1 adipocytes were cocultured in serum-free Dulbecco's modified Eagle's medium with or without ECT for 24 h. Nitric oxide (NO), tumor necrosis factor-α (TNF-α), and monocyte chemoattractant protein-1 (MCP-1) production was measured in the coculture supernatant. ECT decreased the secretion of NO, TNF-α, and MCP-1. The expression of adipogenic proteins, including peroxisome proliferator-activated receptors γ (PPARγ) and CCAAT/enhancer binding protein α (C/EBPα) in cocultured adipocytes and inducible nitric oxide synthase (iNOS) in cocultured macrophages, was inhibited by ECT. Additionally, HO-1 expression was induced in cocultured macrophages and adipocytes. Silencing of HO-1 expression increased the production of NO, TNF-α, and MCP-1 in cocultured cells, in spite of the presence of ECT. This study demonstrated that ECT exhibited anti-inflammatory properties by inhibiting the production of proinflammatory cytokines in the interaction between adipocytes and macrophages through HO-1 expression. ECT may have the potential to improve chronic inflammation in obesity.

Adaptive 4PAM decision feedback equalizer with reduced number of slicers (2017)

This paper presents a comparative study of dual-adaptive DFE for 4PAM serial links with a reduced number of error slicers. Two set of SS-LMS DFE, one for optimal DFE tap coefficients and the other for optimal reference for error generation are employed. The data-dependent nonlinear characteristics of channels and their effect on the choice of the reference for error generation are investigated. We show that the data-dependent nonlinear characteristics of channels give rise to unequal voltage spacing between adjacent data symbols. We further show that the performance of DFE with only one reference is affected by the choice of the reference for error generation with the reference corresponding to D <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> D <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sub> = 11 yielding the best performance. The theoretical findings are verified using the simulation results of a 2 Gbps serial link over a 10-inch FR4 channel designed in an IBM 130 nm CMOS technology.
Percutaneous Nephrostomy: Technical Aspects and Indications (2011)

First described in 1955 by Goodwin et al as a minimally invasive treatment for urinary obstruction causing marked hydronephrosis, percutaneous nephrostomy (PCN) placement quickly found use in a wide variety of clinical indications in both dilated and nondilated systems. Although the advancement of modern endourological techniques has led to a decline in the indications for primary nephrostomy placement, PCNs still play an important role in the treatment of multiple urologic conditions. In this article, the indications, placement, and postprocedure management of percutaneous nephrostomy drainage are described.
NEW TECHNIQUES FOR RELIABLE PILE INSTALLATION AND PILE BEHAVIOR DESIGN AND ANALYSIS (1994)

Recent advances in rig-mounted computer-controlled monitoring and recording of pile-installation processes have allowed reliable and high-quality control to be developed. An automatic method for assessing the quality of continuous-flight-auger (CFA) pile-installation data, recorded during construction, is now well proven and most successful as both a management tool and as part of internal quality control of Cementation Piling & Foundations Limited in the United Kingdom. The data contain all the pertinent control parameters that when analyzed can identify important imperfections in the pile construction. The impact of these anomalies on the foundation behavior may then be assessed and any additional pile testing or corrective action prescribed if appropriate. Computers have also found their way into the practice of static load-testing for which they may be employed to monitor the pile-head displacement and the load applied by using electronic sensors. In addition, they can be made to control directly the load applied with regularity and accuracy that are unsurpassed. The quality of data returned from such test equipment has promoted the development of pile-behavioral models that have demonstrated remarkable accuracy in characterizing the measured pile behavior. The advances in this field are significant to soil mechanics generally, not just to pile behavior. The technique for modeling pile behavior under load has been developed into an important foundation-design tool that also allows the introduction of a sensible partial-factoring system that can be applied according to specific design conditions.
Position estimation of mobile robots based on coded infrared signal transmission (1997)

A system based on coded infrared signal transmission for the estimation of position of mobile robots in a structured environment is reported. Particular emphasis is placed on the polar coordinate arrangement in which signals are sent from the transmitters situated at the corners of the boundaries of operation. A multisensor system, strategically situated onboard the robot, has been found to improve the accuracy of the position estimation substantially. The information detected by the sensors is suitably processed to calculate the central position of the robot geometrically. The algorithms for the position calculations and the operational strategy are presented. This system forms the basis for the coordination and cooperation philosophy of multiple mobile robots sharing the same environment and performing cooperative or competitive tasks.

Silencing of Bruton's tyrosine kinase (Btk) using short interfering RNA duplexes (siRNA) (2002)

Tec family tyrosine kinases, Bruton's tyrosine kinase (Btk), Itk, Bmx, Tec, and Txk, are multi-domain proteins involved in hematopoietic signaling. Here, we demonstrate that human Btk protein can transiently be depleted using double-stranded short RNA interference (siRNA) oligonucleotides. Imaging and Western blotting analysis demonstrate that Btk expression is down regulated in heterologous systems as well as in hematopoietic lineages, following transfection or microinjection of Btk siRNA duplexes. The induction of histamine release, a pro-inflammatory mediator, in RBL-2H3 mast cells was reduced by 20-25% upon Btk down regulation. Similar, results were obtained when the Btk activity was inhibited using the kinase blocker LFM-A13. These results demonstrate a direct role of Btk for the efficient secretion of histamine in allergic responses.
Recognition and localization of solid objects by a monocular vision system for robotic tasks (2002)

In this paper, we present a model-based vision system using a CCD camera mounted on the end-effector of an industrial robot. We describe an autonomous monocular vision system which is used as a feedback signal to control the position and orientation of the manipulator with respect to a dynamic object part of a 3D scene. Without any previous knowledge of the part's placement or motion, this visual feedback would allow a robot to track a pattern in real time. Applications for such a vision-guided robot include 3D object recognition, by extracting 2D image features and rebuilding 3D features. This is performed via rigidity constraint and search comparison in model database geometric inference. Kinematic redundancy is used for general solution of joint velocity represented by the generalized inverse of Jacobian matrix. The problem of redundancy utilization can generally be formulated in the framework of tasks with the order of priority. We present a visual servoing scheme using the task function approach in term of 6 degrees of freedom of robot's gripper regulation. Redundancy theory allows to control position and orientation of the end-effector of an industrial robot in less than 80 ms of cycle time.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
