A Direct-Digitizer Interface Based on Dual-Slope Technique for Giant Magneto-Resistance Sensors (2018)

A Digital Interface, based on Dual-slope concept, for Giant Magneto-Resistance (GMR) sensors is proposed in this paper. The proposed scheme processes both the sensing GMR elements present in the sensor, using two effective integration periods, and attains a linear digital indication of the applied magnetic field. The scheme does not use any explicit and expensive instrumentation amplifiers or analog-to-digital converters in its architecture. A detailed mathematical analysis of the working principle proves the linear transfer relation of the proposed circuit. Extensive performance studies have been performed with this scheme. Simulation result shows that the worst-case output non-linearity is 0.005 %. Experimental studies have been carried out with synthesized and commercial GMR sensor bridges. Linear transfer characteristics of the developed digitizer were observed through these studies. The developed interface performs better than the conventional schemes and can be used in many application areas like non-intrusive current/angle measurement.
USAGE OF MULTIPLE LIDAR SENSORS ON A MOBILE SYSTEM FOR THE DETECTION OF PERSONS WITH IMPLICIT SHAPE MODELS (2018)

Abstract. The focus of this paper is the processing of data from multiple LiDAR (light detection and ranging) sensors for the purpose of detecting persons in that data. Many LiDAR sensors (e.g., laser scanners) use a rotating scan head, which makes it difficult to properly timesynchronize multiple of such LiDAR sensors. An improper synchronization between LiDAR sensors causes temporal distortion effects if their data are directly merged. A merging of data is desired, since it could increase the data density and the perceived area. For the usage in person and object detection tasks, we present an alternative which circumvents the problem by performing the merging of multi-sensor data in the voting space of a method that is based on Implicit Shape Models (ISM). Our approach already assumes that there exist some uncertainties in the voting space. Therefore it is robust against additional uncertainties induced by temporal distortions. Unlike many existing approaches for object detection in 3D data, our approach does not rely on a segmentation step in the data preprocessing. We show that our merging of multi-sensor information in voting space has its advantages in comparison to a direct data merging, especially in situations with a lot of distortion effects.
Refrigerated Fruit Storage Monitoring Combining Two Different Wireless Sensing Technologies: RFID and WSN (2015)

Every day, millions of tons of temperature-sensitive goods are produced, transported, stored or distributed worldwide, thus making their temperature and humidity control essential. Quality control and monitoring of goods during the cold chain is an increasing concern for producers, suppliers, logistic decision makers and consumers. In this paper we present the results of a combination of RFID and WSN devices in a set of studies performed in three commercial wholesale chambers of 1848 m3 with different set points and products. Up to 90 semi-passive RFID temperature loggers were installed simultaneously together with seven motes, during one week in each chamber. 3D temperature mapping charts were obtained and also the psychrometric data model from ASABE was implemented for the calculation of enthalpy changes and the absolute water content of air. Thus thank to the feedback of data, between RFID and WSN it is possible to estimate energy consumption in the cold room, water loss from the products and detect any condensation over the stored commodities.
Astrocytes in the Rat Nucleus Tractus Solitarii Are Critical for Cardiovascular Reflex Control (2013)

We have shown that an antibody to dopamine-β-hydroxylase conjugated with saporin (anti-DBH-SAP) damages catecholamine neurons in the nucleus tractus solitarii (NTS) of rat, attenuates arterial baroreflexes, and leads to lability of arterial blood pressure, damage to cardiac myocytes, and, in some animals, sudden death. However, others have shown that injection of 6-hydroxydopamine (6-OHDA), a toxin devoid of saporin, also damaged NTS catecholamine neurons but did not lead to these cardiovascular changes. We found similar cardiovascular changes after injecting a different SAP conjugate to target NTS neurons with neurokinin (NK1) receptors. Because ribosome-inactivating proteins may be toxic to glia, we hypothesized that SAP, a ribosome-inactivating protein, might target glia whose loss could account for physiological changes. We tested this hypothesis by assessing effects on select neurons and on glia in the NTS after exposure to SAP, targeted SAP conjugates, or 6-OHDA. SAP and all SAP conjugates led to loss of immunoreactivity for glial fibrillary acidic protein, a marker for astrocytes, in the NTS while 6-OHDA did not. As reported previously, anti-DBH-SAP selectively killed noradrenergic neurons in the NTS while SAP conjugated to stabilized substance P (SSP-SAP) selectively killed neurons with NK1 receptors. In contrast, SAP produced no demonstrable neuronal damage. All injections led to activation of microglia in the NTS; however, only SAP and its conjugates attenuated cardiovascular reflexes while also producing lability of arterial pressure, damage to cardiac myocytes, and in some animals, sudden death. Thus, NTS astrocytes may play a role in mediating cardiovascular reflex transmission through the NTS.
[Association between levels of plasma lipid profile with apolipoprotein B gene polymorphism in 93 children]. (1998)

To certain extent, there is association between polymorphism of Xba I locus of Apo B gene and levels of plasma lipid profile in children, which may be a genetic marker for abnormal level of plasma lipid profile during childhood.
Implementation of a 4D fast SLAM including volumetric sum of the UAV (2012)

Traditionally, Simultaneous Localization and Mapping (SLAM) involved a development of map using the actual map coordinates, with the robot itself occupying some 3-dimensional space. SLAM forms an indispensable part of navigation system of an autonomous system. In this paper, we try to assess a method for implementation of a full 4D (4 degree of freedom) solution to SLAM using range and bearing sensors LIDAR (light detection and ranging) and camera for indoor navigation and GPS for outdoor navigation coupled with an Inertial Navigation System (INS) which include inertial sensors such as gyroscopes and accelerometer along with a magnetometer. The method for the Unmanned Aerial Vehicle (UAV) is further modified through volumetric addition into Landmarks and thus into map, in our SLAM procedure in order to decrease the computational complexities and also increase the efficiency of the collision detection algorithms. The UAV motions are restricted to the motion in the three degrees of freedom and yaw, while the pitch and roll are neglected as the UAV is always restricted to move at a constant altitude for a stipulated time-period. This method is significant as it serves for UAV's as Fast SLAM served for ground vehicles.
Impaired coronary collateral vessel development in patients with metabolic syndrome (2005)

We have shown for the first time that the development of coronary collateral vessels is poorer in patients with metabolic syndrome with advanced ischemic heart disease than in control participants without metabolic syndrome. Thus, it can be suggested that metabolic syndrome is one of the significant factors affecting the development of coronary collateral vessels adversely.
Development of new scintillators for medical applications (2015)

For a long time the discovery of new scintillators has been more serendipitous than driven by a deep understanding of the mechanisms at the origin of the scintillation process. This situation has dramatically changed since the 1990's with an increased demand for scintillators of better performance for large particle physics experiments as well as for medical imaging. It is now possible to design a scintillator for a specific purpose. The bandgap can be adjusted, the traps energy levels and their concentration can be finely tuned and their influence can be damped or on the contrary enhanced by specific doping for an optimization of the performance of the scintillator. Several examples are given in this paper of such crystal engineering attempts to improve the performance of crystal scintillators used in medical imaging devices. An attention is also given to spectacular progress in crystal production technologies, which open new perspectives for large scale and cost effective crystal production with consistent quality.
Production of a monoclonal antibody against the alpha 4 beta 7 integrin (2009)

This study describes an attempt to produce a monoclonal antibody (mAb) against the human alpha 4 beta 7 (a4(37) gut-homing integrin found on lymphocytes. The recruitment of lymphocytes via the a4[37 receptor to the gut has been associated with inflammatory bowel disease (IBD). A novel immunization strategy was employed in generating polyclonal antibodies (pAb) in C57BL/6 mice. (37 knock-out (K/O) mice were immunized with (37 wild-type (WT) mouse splenocytes with cell-surface (37. As a final boost, mice were injected with human peripheral blood mononuclear cells (PBMC), with a rationale of boosting epitopes shared between murine and human (37. Immune sera and clones generated by hybridoma technology were screened using the enzyme-linked immunosorbent assay (ELISA) and flow cytometry. Despite binding to both mouse cells and PBMCs expressing a4(37, the mAb produced is unlikely to be anti-a4(37 because it generated a different staining pattern than the positive control, ACT-1, on T cell subsets that migrate to the gut. worthwhile. Her guidance, supervision and expertise have taught me a great deal. I would also like to especially thank Dr. John Boothby for his continuous support since I began my MS program.
Trapped Particles and Echoes (1969)

The investigation of trapped particles in a negative electrostatic well by small perturbing pulses (separation $\ensuremath{\tau}$) reveals long trapping time and anharmonic orbits. New echoes occurring at fractions of $\ensuremath{\tau}$ are observed whose frequencies are harmonics of the main echo frequency. These temporal trapped-ion echoes are very sensitive to local turbulence.
Comparison of Six Commercially Available Transport Media for Maintenance of <i>Serpulina (Treponema) Hyodysenteriae</i> (1992)

Two anaerobic (A1 and A2), 1 selective (S1), and 3 conventional (C1, C2, and C3) transport media formulations were compared for their capacity to maintain the viability of Serpulina (Treponema) hyodysenteriae. Initial experiments compared the recovery of S. hyodysenteriae from pure cultures held in each transport medium for 0.5, 1, 2, 3, 5, and 7 days at -40 C, 4 C, 25 C, and 36 C. Subsequent experiments compared each transport medium for maintenance of S. hyodysenteriae in fecal specimens obtained from experimentally infected pigs after holding for up to 7 days at 25 C. In each experiment, the viability of S. hyodysenteriae in each transport medium incubated at each temperature and for each period was determined by inoculating the transport medium onto either trypticase soy agar with 5% sheep blood or selective BJ agar and incubating at 42 C anaerobically. Viability and fecal flora contamination were evaluated blindly after 2-, 4-, and 6-day incubation periods. At -40 C, recovery of viable S. hyodysenteriae from pure culture did not differ among the transport media from 0.5 to 7 days, and all of the transport media consistently maintained the viability of the spirochetes for 7 days. At 4 C, the anaerobic and selective transport media maintained the viability of pure cultures of S. hyodysenteriae significantly better than did the conventional transport media group at day 7 (P = 0.019). At the same temperature, the anaerobic media maintained viability better than did the conventional media at 5 days (P less than 0.042).(ABSTRACT TRUNCATED AT 250 WORDS)
The New Visibility (2008)

The starting point is the idea that the world media produces a new mediated visibility, making visible the actions and events ever more difficult to control. It is an explicit strategy of those who know well be mediated visibility can be a weapon in fighting the daily struggles. This essay briefly outline my thinking the new visibility and its implications. Begin by placing the issue of visibility in the context of a social theory of the media, since - as I will try show - the emergence of a new visibility is defined nitivamente related to new ways of acting and interacting with the media brought.
Synthesis and characterization of new hydrodesulphurization Co–Mo catalysts supported on calcined and pyrolyzed bone (2015)

A series of cobalt–molybdenum catalysts supported on calcined bone (hydroxyapatite, HAP) and pyrolyzed bone (hydroxyapatite–carbon, HAP–C) have been prepared by an impregnation method.
Galactosyltransferases: Physical, Chemical, and Biological Aspect (1985)

Galactosyltransferases (GTs) are one of the members of a family of enzymes called glycosyltransferases involved in the biosynthesis of complex carbohydrates. These enzymes catalyze the transfer of galactose from UDP-galactose to an acceptor (glycoprotein, glycolipid) containing terminal N-acetylglucosamine or N-acetylgalactosamine residue. GTs occur in soluble (milk, serum, effusions, etc.) and insoluble (membrane) forms. The GT activities on the outer surface of the cells have been correlated with a host of cellular interactions, including fertilization, cell migration, embryonic induction, chondrogenesis, contact inhibition of growth, cell adhesion, hemostasis, intestinal cell differentiation, and immune recognition. GTs have been purified to homogeneity using affinity chromatography. Most GTs are found active in the pH range 6 to 8 and at temperatures between 35 to 40 degrees C. Manganese is an essential co-factor for GT activity. Isoenzymes of GT have been recognized, especially in tumor tissues, malignant effusions, and sera of cancer patients using polyacrylamide gel electrophoresis in the presence and absence of SDS. Depending on the source of the enzyme, the molecular weights of GTs range between 40,000 to 80,000 daltons. Carcinoma-associated GT isoenzyme has been reported to have a higher molecular weight than the normal GT isoenzyme. Development of monoclonal antibody against the cancer-specific GT isoenzyme will provide help in the development of an immunoassay for the measurement of this isoenzyme in the sera and an aid in the radioimmunolocalization of the tumors in cancer patients.
Biomedical Implications of Heavy Metals Induced Imbalances in Redox Systems (2014)

Several workers have extensively worked out the metal induced toxicity and have reported the toxic and carcinogenic effects of metals in human and animals. It is well known that these metals play a crucial role in facilitating normal biological functions of cells as well. One of the major mechanisms associated with heavy metal toxicity has been attributed to generation of reactive oxygen and nitrogen species, which develops imbalance between the prooxidant elements and the antioxidants (reducing elements) in the body. In this process, a shift to the former is termed as oxidative stress. The oxidative stress mediated toxicity of heavy metals involves damage primarily to liver (hepatotoxicity), central nervous system (neurotoxicity), DNA (genotoxicity), and kidney (nephrotoxicity) in animals and humans. Heavy metals are reported to impact signaling cascade and associated factors leading to apoptosis. The present review illustrates an account of the current knowledge about the effects of heavy metals (mainly arsenic, lead, mercury, and cadmium) induced oxidative stress as well as the possible remedies of metal(s) toxicity through natural/synthetic antioxidants, which may render their effects by reducing the concentration of toxic metal(s). This paper primarily concerns the clinicopathological and biomedical implications of heavy metals induced oxidative stress and their toxicity management in mammals.
A language independent approach for detecting duplicated code (1999)

Code duplication is one of the factors that severely complicates the maintenance and evolution of large software systems. Techniques for detecting duplicated code exist but rely mostly on parsers, technology that has proven to be brittle in the face of different languages and dialects. In this paper we show that is possible to circumvent this hindrance by applying a language independent and visual approach, i.e. a tool that requires no parsing, yet is able to detect a significant amount of code duplication. We validate our approach on a number of case studies, involving four different implementation languages and ranging from 256 K up to 13 Mb of source code size.
Pattern matching based link quality prediction in wireless mobile ad hoc networks (2006)

As mobile devices are getting more ubiquitous, the paradigm of wireless mobile ad hoc networks (MANETs) is gaining popularity. However, MANETs impose new challenges because of their self-organizing, mobile and error-prone nature. Mobility prediction can mitigate the problems emerging from node mobility.In this paper, we propose an approach called XCoPred to predict link quality variations based on pattern matching which can be exploited for mobility prediction. XCoPred doesn't require the use of any external hardware or reference point. Each MANET node monitors the Signal to Noise Ratio (SNR) of its links to obtain a time series of SNR measurements. When a prediction is required, the node tries to detect patterns similar to the current situation in the history of the SNR values of its links by applying the normalized cross-correlation function. The found matches are then used as the base of the prediction. Simulations have shown that fairly accurate predictions around $2~dB$ of absolute average prediction error can be achieved with XCoPred in case of appropriate parameter settings and scenarios showing clear node mobility patterns.
Modeling and Simulation for Car's Regenerative Braking System (2008)

A kind of regenerative braking system for a car was studied. The parameters of the car were modeled when the car broke or started-up. The car's speed v,acceleration a,the hydraulic accumulator's pressure p and volume V were simulated with Matlab while the car broke and started-up. The hydraulic accumulator can absorb all of the braking energy when braking and the energy stored in the hydraulic accumulator can drive the car to a certain speed so as to make the car start-up itself.
Development of a membrane array‐based multimarker assay for detection of circulating cancer cells in patients with non‐small cell lung cancer (2006)

Combination of multiple mRNA markers has been largely investigated for detection of circulating cancer cells. However, current PCR-based methods are relatively expensive and time consuming. The aim of this study was to develop a membrane array-based multimarker assay for detection of circulating cancer cells in nonsmall cell lung cancer (NSCLC) patients. At first, we selected 22 candidate genes by means of suppression subtractive hybridization and Northern blot analysis. The diagnostic value of each candidate gene was then preliminarily evaluated in 50 pairs of blood samples by membrane array method. Accordingly, 17 genes with area under the ROC curve (AUC) > or = 0.8 were selected as target genes to reconstruct the diagnostic membrane array, which was then used to test peripheral blood samples from 100 NSCLC patients and 147 control subjects. ROC curve analysis demonstrated that the optimal threshold number of overexpressed markers on membrane array for discrimination between NSCLC patients and control subjects was 12. As a result, the diagnostic membrane array could detect circulating cancer cells in 90 (90%) of 100 NSCLC patients and in 14 (9.5%) of 147 control subjects (including 6 of 100 normal persons, 3 of 20 breast cancer patients, 3 of 15 colorectal cancer patients and 2 of 12 gastric cancer patients). Moreover, the detection rate was significantly correlated with NSCLC patients' metastatic status and overall stage (p = 0.028 and 0.014, respectively). These results suggested that our blood-based membrane array assay for molecular detection of circulating lung cancer cells has great potential for clinical applications.
Asynchronous parallel algorithm for mining association rules on a shared-memory multi-processors (1998)

Mining association rules from large databases is an important problem in data mining. There is a need to develop parallel algorithm for this problem because it is a very costly computation process. However, all proposed parallel algorithms for mining association rules follow the conventional level-wise approach. On a sharedmemory multi-processors, they will impose a synchronization in every iteration which degrades greatly their performance. The deficiency comes from the contention on the shared I/O channel when all processors are accessing their database partitions in the shared storage synchronously. An asynchronous algorithm APM has been proposed for mining association rules on shared-memory multiprocessors. All participating processors in APM generate candidates and count their supports independently without synchronization. Furthermore, it can finish the computation with less I/O than required in the level-wise approach. The algorithm has been implemented on a Sun Enterprise 4000 multi-processors with 12 nodes. The experiments show that APM has super performance than other proposed synchronous algorithms.
SrBi<sub>2</sub>Ta<sub>2</sub>O<sub>9</sub>(SBT) thin films prepared by electrostatic spray (1997)

Abstract Ferroelectric SrBi2Ta2O9 (SBT) thin films were deposited on Pt/SiO2/Si substrates by electrostatic spray, and their structural and electrical properties were investigated. The spray-coated films crystallized upon heating at 680°C-760°C. The XRD patterns showed distinct peaks of (105), (110) and (200) orientations. P-E hysteresis loops were observed with a typical coercive field around 55kV/cm. The remanent polarization, 2P r , was above 12μC/cm2 for a 160nm film. The fatigue endurance was good, as the reduction of P r during 1012 switching cycles was less than 10% of its initial value. The electrostatic spray technique is capable of injecting submicron, stoichiometrically correct, metal-organic SBT droplets onto a rotating substrate, and has the potential to achieve a better step coverage than the spin-on technique while keeping its original advantages.
Measuring quality of life in stroke. (1993)

Emphasis should be placed on further psychometric evaluation of existing quality of life measures rather than on generating new instruments. There is particular need for supplementary data on the responsiveness of the instruments to changes in patients' clinical status over time. The choice of a suitable quality of life instrument should be based not only on psychometric properties but also on careful consideration of the research question, the relevance to the objectives of the study, the feasibility of the instrument, and the specific characteristics of the stroke patients under investigation.
