Optimization technique based localization in IEEE 802.11 WLAN

Localization of mobile node using wireless local area network (WLAN) become a most emerging area because of its location based services provided to users. Applications of localization are found in various location based services like intruder identification and detection of possible threat. These applications require physical location of mobile node to be known beforehand. Various localization techniques exist to determine the location of a mobile node in indoor and outdoor environments. In this paper, we propose a new indoor positioning method based on ranging measurement. In this method, location of mobile node is estimated using Newton Raphson (NR) optimization technique. We also compared our proposed method with New- ton Gaussian (NG) and trilateration ranging based techniques. Through extensive simulation, we found that the accuracy of our scheme is better than trilateration and comparable with Newton Gaussian technique.
Planification de mouvement pour tiges élastiques

Le probleme de la planification du mouvement a ete largement etudie dans le cas de corps rigides articules mais peu de travaux considerent les corps deformables. En particulier, les tiges elastiques telles que cables electriques, flexibles hydrauliques et pneumatiques, apparaissent dans de nombreux contextes industriels. Du fait d'une modelisation complexe et d'un grand nombre de degres de liberte, l'extension des methodes de planification de mouvement a de tels corps est un probleme particulierement difficile. En se basant sur les proprietes des configurations a l'equilibre statique, cette these propose plusieurs approches au probleme de planification de mouvement pour des tiges elastiques.
A Review on Overvoltages in Microgrid

Now microgrid has aroused increasing attention due to energy sustainable development and the development of distributed generations (DG), such as micro-turbines, gas turbines, wind power, photovoltaic and fuel cells. This paper introduces the basic structure of microgrid and summarizes the overvoltages that can occur in microgrid, including ground fault overvoltages, resonant overvoltages, overvoltage related to voltage regulation, switching overvoltages of inner microgrid, transfer overvoltages from distribution network (such as lightning and switching overvoltages). By analysis, this paper obtains the following conclusion: resonant overvoltages and lightning stroke transfer overvoltages are the most serious for microgrid.
Understanding professional vision in inquiry science teaching

To understand inquiry science teaching, we must understand how practicing and prospective teachers see the activity of teaching. This study examines how practicing and prospective teachers highlight and code classroom activity in an effort to understand the nature of professional pedagogical vision (Goodwin, 1994). Results indicate that differences exist in terms of: actor focus, questions, grain-size and enactment.
A New Perspective of Neuromyopathy to Explain Intractable Pancreatic Cancer Pains; Dry Needling as an Effective Adjunct to Neurolytic Blocks

We present a new perspective of neuromyopathy in pancreatic cancer pain (PCP) referral to bodywall; proposal of new rationale to include ultrasound guided dry needling (USGDN) of body wall muscles as an effective adjunct to neurolytic coeliac plexus block (NCPB) or splanchnic nerve radiofrequency ablation (SRF) for comprehensive interventional management. Methods: PCP response to SRF in 2 patients and NCPB in 3 patients was documented on numerical rating scale (NRS) on post procedure days 3 and 15. If the residual pain was >5 NRS on day 15, USGDN of abdominal and back muscles was started on a thrice weekly basis. The response to USGDN documented on day 30 after approximately 6 sessions of DN, showed a significant pain reduction (0-2 NRS) with 50% reduction of pre-treatment opioid consumption. This was sustained at 6 months or till their demise. Convergence of visceral and somatic nerves at the dorsal horn (viscerosomatic neurons) causes referral of visceral pain to the back and abdominal muscles. This leads to formation of myofascial trigger points (MTrPs) in the muscles which sets up a parallel network of sensitized peripheral and central motor nociceptive processing (neuromyopathy). USGDN specifically addressed the MTrPs that develop as an epiphenomenon of self-perpetuating neuromyopathy while SRF/NCPB, analgesics and neuromodulators could address only visceral nociceptive afferents (pain mediated through celiac plexus) which forms a meagre 10% of the total spinal cord afferent input. Thus, we conclude that combination of neuromyopathy and viscerosomatic convergence in PCP indicate a specific role for DN as an adjunct to SRF/NCPB in our patients
Synergism between chlorhexidine and sulphadiazine.

Chlorhexidine and sulphadiazine react synergistically against strains of Pseudomonas. Proteus and Staphylococcus, with high factors of synergy. The impermeability of these strains to sulphadiazine is destroyed by low concentrations of chlorhexidine, permitting the accumulation of sulphadiazine which then inhibits protein synthesis. The combination of these drugs is bactericidal.
The gastric marginal zone B-cell lymphoma of MALT type.

Extranodal marginal zone B-cell lymphoma is a discrete clinicopathological entity arising in mucosa-associated lymphoid tissue (MALT) that has commanded increasing attention in recent years because of its unique pathogenetic, histologic, and clinical features. 1-3 Two types of MALT can be identified in disparate organs that do not correspond to peripheral sites of the immune system. The native type consists of lymphoid tissue physiologically present in the gut (eg, Peyer’s patches), whereas acquired MALT develops in sites of inflammation in response to either infectious conditions, such asHelicobacter pylorigastritis, or autoimmune processes, such as myoepithelial sialadenitis (MESA), associated with Sjo ̈gren’s syndrome or Hashimoto’s thyroiditis. 4-6 In the context of these prolonged lymphoid reactive proliferations, the outgrowth of a pathological clone can progressively replace the normal lymphoid population, giving rise to a MALT lymphoma. 7-11
Haematology and blood chemistry values in greyhounds

SIR, — For those veterinary surgeons, and there must be many, who see greyhounds only occasionally in their day-to-day practice and confess to a degree of ignorance about the breed, the Society of Greyhound Veterinarians has recently added to the information on its website, www.greyhoundvets. co.uk
Embolic agents used for bronchial artery embolisation in massive haemoptysis

Massive haemoptysis is a life-threatening disorder that is associated with a high mortality rate. It is mostly caused by bleeding from bronchial circulation. Bronchial artery embolisation is now considered to be the treatment of choice for acute massive haemoptysis. The safety and effectiveness of bronchial artery embolisation for massive haemoptysis has been proved since its first use in 1973. Currently, polyvinyl alcohol (PVA) particles are the most commonly used embolic agent for bronchial artery embolisation worldwide. PVA particles are biocompatible and nonbiodegradable and are considered to be a permanent embolic agent. Gelatin sponge is a temporary embolic agent and can be used as a supplementary agent after initial embolisation with PVA particles. Stainless steel coils are not recommended for embolisation of bronchial artery, although they may be used in the embolisation of internal mammary artery to preserve the normal vascular territory. Recently, the interest in the use of new embolic agents for bronchial artery embolisation is emerging because of inherent limitations of PVA particles as an intravascular embolic agent. Tris-acryl gelatin microspheres are a new embolic agent that is increasingly used for uterine fibroid embolisation. Tris-acryl gelatin microspheres have characteristics that make it an attractive alternative to PVA particles for bronchial artery embolisation. Clinical trials and experimental studies should be performed to explore the safety and efficacy of microspheres for bronchial artery embolisation.
Directional relations composition by orientation histogram fusion

Orientation relations represent a significant component of spatial relations, complementing topological and distance relations, for the description of a spatial scene. The most important operator, in a spatial reasoning model is an operator of composition defining the behavior of the combination of two relations. This paper focuses on the composition of orientation relations modeling by orientation histogram. Composition can be seen as fusion of orientation information derived from the orientation histograms and spatial objects information, represented mainly by vectorial data.
Spotlight on the three main hepatic fibrogenic cells in HCV-infected patients: Multiple immunofluorescence and ultrastructure study

ABSTRACT The present work deals with the simultaneous ultrastructure and triple immunofluorescence study of the three main hepatic fibrogenic cells, hepatic stellate cell, myofibroblast (MF), and fibroblast, in a group of hepatitis C virus (HCV) RNA positive patients, as their exact interrelation behavior in vivo with the progress of hepatic fibrosis is still inadequate. In this study, for the first time, cells having the morphological characteristic of MF and not bone marrow fibrocytes were revealed in liver portal vessels. This necessitates the reevaluation of the available knowledge concerning bone marrow fibrocyte. Also, the distribution, cellular interrelations, and the fate of MF were highlighted.
Identifying the Full-Diversity Solution of MIMO Detection: A Fine-Grained Approach

This paper presents an approach to identifying the full-diversity solution of MIMO detection, which can verify whether a solution obtained by MIMO detection is fulldiversity. The approach is called fine-grained because it is able to individually identify the full-diversity performance for each solution of MIMO detection. To verify the theoretical properties of the developed approach, the conditional probability of missing the correct solution and false alarm, as well as the conditional error probability are analyzed. Besides, a numerical example and practical applications are provided.

Estimation of effective population size and detection of a recent population decline coinciding with habitat fragmentation in a ground beetle

We assess the impact of habitat fragmentation on the effective size (Ne) of local populations of the flightless ground beetle Carabus violaceus in a small (<25 ha) and a large (>80 ha) forest fragment separated by a highway. Ne was estimated based on the temporal variation of allele frequencies at 13 microsatellite loci using two different methods. In the smaller fragment, Ne estimates ranged between 59 and a few hundred, whereas values between 190 and positive infinity were estimated for the larger fragment. In both samples, we detected a signal of population decline, which was stronger in the small fragment. The estimated time of onset of this Ne reduction was consistent with the hypothesis that recent road constructions have divided a continuous population into several isolated subpopulations. In the small fragment, Ne of the local population may be so small that its long‐term persistence is endangered.
Nef-Induced CD 4 Endocytosis in Human Immunodeficiency Virus Type 1 Host Cells : Role of p 56 lck Kinase §

Human immunodeficiency virus type 1 (HIV-1) Nef interferes with the endocytic machinery to modulate the cell surface expression of CD4. However, the basal trafficking of CD4 is governed by different rules in the target cells of HIV-1: whereas CD4 is rapidly internalized from the cell surface in myeloid cells, CD4 is stabilized at the plasma membrane through its interaction with the p56 kinase in lymphoid cells. In this study, we showed that Nef was able to downregulate CD4 in both lymphoid and myeloid cell lines but that an increase in the internalization rate of CD4 could be observed only in lymphoid cells. Expression of p56 in nonlymphoid CD4-expressing cells restores the ability of Nef in order to increase the internalization rate of CD4. Concurrent with this observation, the expression of a p56-binding-deficient mutant of CD4 in lymphoid cells abrogates the Nef-induced acceleration of CD4 internalization. We also show that the expression of Nef causes a decrease in the association of p56 with cell surface-expressed CD4. Regardless of the presence of p56, the downregulation of CD4 by Nef was followed by CD4 degradation. Our results imply that Nef uses distinct mechanisms to downregulate the cell surface expression levels of CD4 in either lymphoid or myeloid target cells of HIV-1.
In search of a vaccine for respiratory syncytial virus: the saga continues.

More than 150 years ago, Eberle described bronchiolitis in infancy: the disease "commences with cough and breathing [and] soon becomes laborious and wheezing. The cough is at first dry, attended with a wheezing sound in the chest; but towards the termination of the complaint it frequently becomes humid and rattling" (p. 222) [1]. This descriptive portrayal of respiratory syncytial virus (RSV) bronchiolitis remains accurate today. RSV epidemics continue to be characterized by lower respiratory tract disease in young infants, sleepless anxiety in parents, and increased workloads for medical personnel. It is now recognized that RSV is the major cause of respiratory tract disease in infants worldwide [2] and that infection with this virus consistently results in the increased use of health-care resources, including visits to physicians and the occupancy of hospital beds [3]. The importance of RSV in causing disease and morbidity in adults-part cularly in the debilitated and elderly-is also now appreciated [4]. It is known that, to prevent severe disease in infants, high levels of RSV-specific antibody can be administered as a monthly injection [5], but the costs of this antibody prophylaxis force health-care providers to make difficult choices when confronted by both expanding populations of high-risk infants and limited budgets. The seriousness and ubiquity of RSV disease was recognized and characterized by astute clinicians and researchers beginning in the late 1950s [6], although histologically confirmed disease from a 1937 outbreak was described as early as 1941 by Adams (figure 1) [7]. Propagation of the viral agent, obtained from infants with bronchiolitis, was reported from Chanock's laboratory at the National Institutes of Health (NIH) in 1957 [8], and RSV vaccine development began shortly after this time. This laboratory confirmed that this virus was the causal agent of "chimpanzee coryza," described a year earlier by Morris et al. [9]. By 1969, it was stated with confidence that "RS virus has been
Penicillinase producing gonococci: a spent force?

Sir, The experience of Ison et al of penicillinase producing Neisseria gonorrhoeae (PPNG) being a spent force in London' is echoed in Leicester, where we have seen a dramatic fall in cases since 1983. In that year we saw a total of 68 new patients infected with PPNG strains out of a total of 555 cases of gonorrhoea, and during March 1983 the proportion of gonorrhoea caused by PPNG strains was 31%. The initial epidemic was quelled by careful contact tracing and appropriate chemotherapy with spectinomycin, ampicillin, probenecid, or augmentin. Since then the number of PPNG strains has decreased, so that in 1986 we saw only five cases, and so far in 1987 there have been three cases. We feel that despite the valiant effort on the part of the gonococcus to adapt itself to a changing world, it too will soon be joining the treponeme in "the second division" of genitourinary medicine. Yours faithfully, Peter Fisk* Andrew Lewist *Department of Genitourinary Medicine, Leicester Royal Infirmary, and tMedical School, University of Leicester, Leicester LEI 7RH
S " L 3143 436021 Optiml Adaptive Esimtion of hDW Thim

This work presents an adaptive approach to the problem of estimating a sampled, scalar-valued, stochastic process described by an initially unknown parameter vector. Knowledge of this quantity completely specifies the statistics of the process, and consequently the optimal estimator must "learn" the value of the parameter vector. In order that construction of the optimal estimator be feasible it is necessary to consider only those processes whose parameter vector comes from a finite set of a priori known values. Fortunately, many practical problems may be represented or adequately approximated by such a model. The optimal estimator is found to be composed of a set of elemental estimators and a corresponding set of weighting coefficients, one pair for each possible value of the parameter vector. This structure is derived using properties of the conditional mean operator. For gaussmarkov processes the elemental estimators are linear, dynamic systems, and evaluation of the weighting coefficients involves relatively simple, nonlinear calculations. The resulting system is optimum in the sense that it minimizes the expected value of a positive-definite, quadratic form in terms of the error (a generalized mean-square-error criterion). Because the system described in this work is optimal, it differs from previous attempts at adaptive estimation, all of which have used approximation techniques or suboptimal, sequential, optimization procedures. Two examples showing the improvement of an adaptive filter as compared to a conventional filter are presented and discussed.
Measurement of radiation dose in cerebral CT perfusion study.

PURPOSE To evaluate radiation dose in cerebral perfusion studies with a multi-detector row CT (MDCT) scanner on various voltage and current settings by using a human head phantom. MATERIALS AND METHODS Following the CT perfusion study protocol, continuous cine scans (1 sec/rotation x60 sec) consisting of four 5-mm-thick contiguous slices were performed three times at variable tube voltages of 80 kV, 100 kV, 120 kV, and 140 kV with the same tube current setting of 200 mA and on variable current settings of 50 mA, 100 mA, 150 mA, and 200 mA with the same tube voltage of 80 kV. Radiation doses were measured using a total of 41 theroluminescent dosimeters (TLDs) placed in the human head phantom. Thirty-six TLDs were inside and three were on the surface of the slice of the X-ray beam center, and two were placed on the surface 3 cm caudal assuming the lens position. RESULTS Average radiation doses of surface, inside, and lens increased in proportion to the increases of tube voltage and tube current. The lowest inside dose was 87.6+/-15.3 mGy, and the lowest surface dose was 162.5+/-6.7 mGy at settings of 80 kV and 50 mA. The highest inside dose was 1,591.5+/-179.7 mGy, and the highest surface dose was 2,264.6+/-123.7 mGy at 140 kV-200 mA. At 80 kV-50 mA, the average radiation dose of lens was the lowest at 5.5+/-0.0 mGy. At 140 kV-200 mA the radiation dose of lens was the highest at 127.2+/-0.6 mGy. CONCLUSION In cerebral CT perfusion study, radiation dose can vary considerably. Awareness of the patient's radiation dose is recommended.
Bovine Somatic Cell Nuclear Transfer Using Recipient Oocytes Recovered by Ovum Pick-Up: Effect of Maternal Lineage of Oocyte Donors1

Abstract The efficiency of bovine nuclear transfer using recipient oocytes recovered by ultrasound-guided follicle aspiration (ovum pick-up [OPU]) was investigated. Oocyte donors were selected from 2 distinct maternal lineages (A and B) differing in 11 nucleotide positions of the mitochondrial DNA control region. A total of 1342 cumulus-oocyte complexes (COCs) were recovered. The numbers of total COCs and class I/II COCs recovered from donors of lineage A were higher (P < 0.001) than those obtained from lineage B. Follicle aspiration once per week yielded a higher (P < 0.001) total number of COCs per session than aspiration twice per week, whereas the reproduction status of donors (heifer vs. cow) had no effect on OPU results. Of the 1342 oocytes recovered, 733 (55%) were successfully matured in vitro and used for nuclear transfer. Fusion was achieved in 550 (75%) karyoplast-cytoplast complexes (KCCs), resulting in 277 (50%) cleaved embryos on Day 3. On Day 7 of culture, 84 transferable embryos (15% based on fused KCCs) were obtained. After 38 transfers (10 single, 22 double, and 6 triple transfers), 9 recipients (8 double and 1 triple transfer) were diagnosed as pregnant on Day 28, corresponding to a pregnancy rate of 24%. The proportion of transferable embryos on Day 7 was significantly (P < 0.05) influenced by maternal lineage of oocyte donors and by the frequency of follicle aspiration. Our study demonstrates the feasibility of generating nuclear transfer embryos with defined cytoplasmic background. These will be valuable tools to experimentally dissect the effects of nuclear and cytoplasmic components on embryonic, fetal, and postnatal development.
Analysis and design of ultracapacitor-boosted back-up power supply for tramcars

The back-up power supply of a tramcar can be boosted and/or redimensioned by refurnishing the existing batteries with peak power storage elements such as ultracapacitors. As a result, the primary battery's lifetime increases and overall reliability is improved, which is essential regarding passengers' safety in some critical circumstances like emergency braking. The current paper points out existing problems and presents some ultracapacitor calculation examples and brings simulation results for better illustration.
Determination of nimodipine in plasma by HPLC-MS/MS and pharmacokinetic application

To develop and validate a rapid, specific and highly sensitive method to quantify nimodipine in human plasma using dibucaine as the internal standard (IS). The analyte and IS were extracted from plasma samples by liquid-liquid extraction using hexane-ethyl acetate (1:1 v/v). The chromatographic separation was performed on a Varian® Polaris C18 analytical column (3 μm, 50 x 2.0 mm) and pre-column SecurityguardTM C18 (4.0 x 3.0 mm) with a mobile phase of Acetonitrile-Ammonium acetate 0.02 ml/L (80:20v/v). The method had a chromatographic run time of 4.5 min and linear calibration curve over the range of 0.1- 40 ng/mL (r > 0.9938). The limit of quantification was 100 pg/mL. Acceptable precision and accuracy were obtained for concentrations over the standard curve ranges. This validated method was successfully applied in determining the pharmacokinetic profile of nimodipine tablets of 30 mg administered to 24 healthy volunteers. The proposed method of analysis provided a sensitive and specific assay for nimodipine determination in human plasma. The time for the determination of one plasma sample was 4.5 min. This method is suitable for the analysis of nimodipine in human plasma samples collected for pharmacokinetic, bioavailability or bioequivalence studies in humans.
