Research on People Counting Based on Stereo Vision (2013)

In both industrial field and office building, the accurate statistic of people who enter or leave the elevator has important practical meaning in security and analysis of passenger flow. We present a binocular vision system to count the people pass by. The camera is set in the height of 2.45 meters to monitor the people overhead in order to reduce the overlap of pedestrians. The object segment and tracking method proposed in this paper show good result with the disparity map gained by the dual-camera. Dynamic promotion of threshold is used in the object segmentation. Feature matching is used to track the moving objects. The system can get the number of people accurate and timely. Experiment results show that our system has good performance under relatively complex circumstance.
Java as an Intermediate Language (1996)

We present our experiences in using Java as an intermediate language for the high-level programming language NESL. First, we describe the design and implementation of a system for translating VCODE - the current intermediate language used by NESL - into Java. Second, we evaluate this translation by comparing the performance of the original VCODE implementation with several variants of the Java implementation. The translator was easy to build, and the generated Java code achieves reasonable performance when using a just-in-time compiler. We conclude that Java is attractive both as a compilation target for rapid prototyping of new programming languages and as a means of improving the portability of existing programming languages.
Connective tissue response to fractionated thermo‐ablative Erbium: YAG skin laser treatment (2010)

Indications for and prevalence of laser therapies with a fractionated laser beam have risen significantly. However, as of yet, little is known about the underlying molecular changes, especially with respect to dermal extracellular-matrix remodelling, wound healing and inflammation. This study aimed at the investigation of the connective tissue response of sun-damaged skin following fractionated laser treatment. Seven patients received a laser therapy on the lateral side of the neck of wrinkles grade III-IV (Glogau scale) using a fractionated thermo-ablative erbium yttrium aluminium garnet (Er:YAG) laser (2940 nm, BURANE XL; Quantel Derma, Erlangen, Germany). Skin biopsies were taken at baseline from untreated skin, 1 and 6 weeks after laser intervention to investigate hyaluronan (HA), collagen-I (Coll-I) and collagen-III (Coll-III) remodelling as well as alteration of matrix metalloproteinase 1 expression (MMP-1). To address this issue, HA synthesizing (HA synthetases, HAS) and degrading (hyaluronidases, HYAL) enzymes were measured at mRNA-level using a real-time PCR. Furthermore, immunohistochemical staining for HA was performed by using the HA binding protein (HAbP) and for Coll-I, Coll-III and MMP-1 by using monoclonal antibodies. The degree of inflammation was correlated descriptively. Our findings were that at the two examined read out points, HAS and HYAL showed a slight response alluding to HA synthesis under minimal signs of inflammatory reaction. Concordantly, although to a varying degree, an increase in the HA content of the skin after laser treatment could be detected by immunhistochemistry. During remodelling, Coll-I, Coll-III and MMP-1 showed a cyclic course with a peak after 1 week. Conclusively, our results indicate a light alteration of the HA metabolism towards synthesis and a transient collagen neogenesis caused by a single fractionated thermo-ablative laser skin intervention. Clinical improvement might be attributed to synergistic effects between collagen neogenesis and the water binding capacities of HA and its influence on skin contraction and remodelling.
Survey on infection and antibiotic resistance rates of Escherichia coli in pork and chicken meat at some markets in Buon Ma Thuot city in 2021 (2022)

To find out the infection rate, and the rate of resistance to common antibiotics of E. coli strains in some types of raw meat, contributing to the prevention of food poisoning and foodborne diseases, we conducted the study: &amp;ldquo;Survey on infection status and antibiotic resistance rate of E. coli in pork and chicken meat at some traditional markets in Buon Ma Thuot city in 2021&amp;rdquo;. The study aimed to determine the infection rate of E. coli strains in pork and chicken meat at markets in Buon Ma Thuot city in 2021, and determine antibiotic resistance rates of isolated strains of E. coli. The rate of E.coli infection on fresh meat was 90.59%, of which 42.35% of samples exceeded the maximum level. The rate of E.coli infection on fresh pork and chicken meat at traditional markets was 95.00% and 86.70%, respectively. The overall rate of antibiotic resistance was 96.75%; Amoxicillin was resistant with the highest rate (93.51%) and the lowest rate was ceftazidime (19.48%). General antibiotic resistance by sample type was 91.56%, from pork was 87.18%, from chicken was 96.05%.
Pneumococcal carriage and serotype distribution among children with and without pneumonia in Mozambique, 2014-2016 (2018)

Vaccine-type pneumococcal colonization remains common among children with and without pneumonia post-PCV10 introduction in Mozambique. In a population of children with high antibiotic exposure, the use of PCR for culture-negative NP swabs can improve assessment of pneumococcal colonization and circulating serotypes.
High Energy Density Nanocomposites Based on Surface-Modified BaTiO3 and a Ferroelectric Polymer (2009)

The dielectric permittivity and electric breakdown strength of nanocomposites comprising poly(vinylidene fluoride-co-hexafluoro propylene) and phosphonic acid surface-modified BaTiO(3) nanoparticles have been investigated as a function of the volume fraction of nanoparticles. The mode of binding of pentafluorobenzylphosphonic acid on the BaTiO(3) particles was investigated using infrared and (31)P solid-state nuclear magnetic resonance spectroscopy, and the phosphonic acid was found to form well ordered, tightly bound monolayers. The effective permittivity of nanocomposites with low volume fractions (<50%) was in good agreement with standard theoretical models, with a maximum relative permittivity of 35. However, for nanoparticle volume fractions of greater than 50%, the effective permittivity was observed to decrease with increasing nanoparticle volume fraction, and this was correlated with an increase in porosity of the spin-coated nanocomposite films. The dielectric breakdown strength was also found to decrease with increasing volume fraction of the BaTiO(3) nanoparticles, with an abrupt decrease observed around 10% and a gradual decrease for volume fractions of 20-50%. Comparison of these results with model calculations, using statistical particle packing simulations and effective medium theory for the permittivity and breakdown strength, indicates the important roles of nanoparticle percolation and porosity of the nanocomposites on the dielectric properties. The measured energy density at a field strength of 164 V/mum, well below the breakdown strength, increased to a value of 3.2 J/cm(3) as the nanoparticle volume fraction is increased to 50%, roughly in line with the trend of the permittivity. The calculated maximum energy densities indicate maximal extractable energy (7-8 J/cm(3) at 1 kHz) for two different particle volume fractions, as a result of the interplay of the dependencies of permittivity and breakdown strength on volume fraction.
Antigen-specific immune-suppressor factor in herpes simplex virus type 2 infections of UV B-irradiated mice (1988)

UV B-irradiation (280 to 320 nm) of mice at the site of cutaneous infection with herpes simplex virus type 2 (HSV-2) induced suppressor T-cell circuits that decreased HSV-2-induced proliferative responses of HSV-2-immune lymph node cells. Adoptive transfer experiments indicated that splenocytes from UV B-irradiated HSV-2-infected animals contain L3T4+ cells that suppress proliferative responses in vivo, consistent with suppressor inducer cells. However, following in vitro culture of the splenocytes with HSV-2 antigen, the proliferation of immune lymph node cells was inhibited by Lyt2+ suppressor T cells, consistent with antigen-induced suppressor effector cells. Antigen-specific and nonspecific suppressor factors were fractionated from supernatants of HSV-2-stimulated spleen cells by molecular-sieve chromatography. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis of the Sephadex fraction that contained the antigen-specific suppressor factor, in the presence or absence of 2-mercaptoethanol, defined a 115-kilodalton protein consisting of two disulfide-bound components with molecular sizes of 70 and 52 kilodaltons. The implications of these results with respect to the regulation of HSV-induced cell-mediated immunity following UV B-irradiation are discussed.
Who competes with whom? A demand‐based perspective for identifying and representing asymmetric competition (2005)

Abstract A host of strategic management and marketing issues, including competitive analysis and strategic decision making, hinges on accurately identifying and representing competitive market structures. It is readily acknowledged that competitive market structures are typically asymmetric; namely, one firm may actively compete with another in a given market but not vice versa. However, empirical efforts to assess these competitive asymmetries have been lacking in the strategy literature. We propose a new spatial methodology to identify and represent asymmetric competitive market structures. Specifically, we devise a new stochastic multidimensional scaling procedure that is calibrated from actual consumer consideration/choice sets to estimate and uncover competitive asymmetries. The proposed methodology can be effectively employed in the analysis of appropriate data from either demand‐ or supply‐side approaches to assess competitive market structure. We illustrate our proposed methodology with survey data collected from two different commercial applications: one from the U.S. luxury automobile market and the other from the U.S. portable telephone market. We contrast the findings of the proposed methodology against traditional symmetric approaches for identifying and representing competitive market structures, and discuss the respective strategic insights.

<title>Moderate Resolution Imaging Spectroradiometer (MODIS) instrument onboard data processing and control system</title> (1993)

The moderate-resolution imaging spectroradiometer (MODIS) instrument is currently being designed at Santa Barbara Research Center to be flown on board the earth observation system (EOS) polar orbiting spacecraft. The MODIS measures the scene radiance in 36 spectral bands from the visible to the long wave infrared regions with high radiometric accuracy and an instantaneous field of view (FOV) of 250, 500, and 1000 meters at nadir. Two on board microprocessors are used to control the instrument subsystems, and supervise the data acquisition and packet formatting. This paper describes the MODIS multiprocessor architecture, the on board data processing, the command and control subsystem, and the flight software necessary to run the instrument with a high degree of reliability.
mCS: a control and supervision device for power plants (2003)

MCS is a microprocessor device for the control, management, and monitoring of power plants, specified by SIP and designed by ITALTEL as part of the realization of a power plant supervision and control system. The device consists of a microcomputer, keyboard and display, and an I/O interface, of which the first two are standard, and the third dedicated for the particular plant. The nature of the structure simplifies man-machine interaction, permitting the management of plant and the displaying of measurements, apparatus status etc. on two levels: local by keyboard and display, and remote by linkage with the supervision center. The authors describe mCS, illustrating its structural and functional characteristics from both the hardware and software points of view.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Medicinal Applications of Perfluoroalkylated Chain-Containing Compounds (2014)

Compounds with polyfluorinated molecular fragments possess unique properties associated with the presence of a large number of fluorine atoms that affect lipophilicity and conformational rigidity of the parent molecule along with other effects. The aim of this review is to provide an overview of synthesized compounds possessing perfluoroalkylated or polyfluorinated chains that have been tested for bioactivity or as potential drug candidates for the treatment of various diseases. As far as the length of the perfluoroalkylated chain is concerned the focus is centered on the compound bearing perfluoroethyl or tetrafluoroethyl as well as longer chains. The perfluoroalkylated compounds discussed are classified according to their biological activity.
A Virtual Reality-Based System for Hand Diagnosis and Rehabilitation (1997)

This article describes a new and unified approach to computerized hand diagnosis and rehabilitation. The system uses a workstation to automate diagnosis data collection and analysis and to assess the rehabilitation progress. A new diagnosis glove was developed and tested. This device measures grasping forces applied to 16 regions of the hand. A physician using this system can also utilize modern diagnosis devices such as electronic dynamometer, pinchmeter, and goniometer. Additionally, three VR rehabilitation exercises were created using WorldToolKit graphics library and run on the same workstation. These exercises were modeled after standard hand rehabilitation procedures and involve manipulation of virtual objects and transparent real-time data gathering. Grasping forces were modeled and fed back using the Rutgers Master worn on the patient's hand. An Oracle database was used to store, analyze, and integrate the patient's diagnosis and rehabilitation data. The system is presently undergoing clinical trials.

The air-sea interface and surface stress under tropical cyclones (2014)

Tropical cyclone track prediction is steadily improving, while storm intensity prediction has seen little progress in the last quarter century. Important physics are not yet well understood and implemented in tropical cyclone forecast models. Missing and unresolved physics, especially at the air-sea interface, are among the factors limiting storm predictions. In a laboratory experiment and coordinated numerical simulation, conducted in this work, the microstructure of the air-water interface under hurricane force wind resembled Kelvin-Helmholtz shear instability between fluids with a large density difference. Supported by these observations, we bring forth the concept that the resulting two-phase environment suppresses short gravity-capillary waves and alters the aerodynamic properties of the sea surface. The unified wave-form and two-phase parameterization model shows the well-known increase of the drag coefficient (Cd) with wind speed, up to ~30 ms(-1). Around 60 ms(-1), the new parameterization predicts a local peak of Ck/Cd, under constant enthalpy exchange coefficient Ck. This peak may explain rapid intensification of some storms to major tropical cyclones and the previously reported local peak of lifetime maximum intensity (bimodal distribution) in the best-track records. The bimodal distribution of maximum lifetime intensity, however, can also be explained by environmental parameters of tropical cyclones alone.
Quantitative assessment of the spatial distribution of low attenuation areas on X-ray CT using texture analysis in patients with chronic pulmonary emphysema. (1997)

An automated and quantitative assessment of the spatial distribution of low attenuation areas (LAA) on X-ray CT was performed using texture analysis in chronic pulmonary emphysema (CPE) patients. LAA was defined as those areas having a density less than the mean minus one SD of the control (-960 HU). The probability of change from non-LAA to LAA between a given pair of pixels with horizontal intervals of i pixels (RNi) was evaluated, because this reflects the interaction between LAA and non-LAA regions with different resolutions. The relationship between the percentage area of the LAA over the total area of the entire lung field (LAA%) was subsequently estimated. The RNi increased sharply as the i value increased from 1 to 5, but then almost became a plateau for i values larger than 5. This suggests that the fundamental structures in the LAA areas ranged from 1 x 1 to 5 x 5 pixels in size. RN1-LAA% and RN5-LAA% plots produced curves which were convex, with peak values at approximately 50 LAA% of 0.09 and 0.18, respectively. In the RN5/RN1-LAA% plot, the RN5/RN1 ratio remained constant at 2.0 regardless of the LAA%. A random process simulation was performed to determine the patterns of LAA proliferation if the spatial distribution of the LAA units was random. When the unit size was kept constant, the results of the simulation did not fit the empirical relationship between the LAA% and the three parameters (RN1, RN5 and RN5/RN1). The simulation provided the best-fitting curves when the unit size of the LAA increased in proportion with the LAA%, starting from a 1 x 1 pixel size increasing at a ratio 1 x 1/(5 LAA%). This suggested that the LAA units do not proliferate randomly in spatial orientation at a fixed unit size, but rather spread throughout the whole lung field in a congregated form whilst increasing their unit size. Thus, it may be concluded that healthy lung tissues near emphysematous lesions have a high probability of suffering from emphysema in the future. This may be due to a direct effect of the neighboring emphysematous lesion or due to a pathologic change in the larger bronchii which dominate both the healthy tissues and the emphysematous lesions.
Epitaxial growth of ferroelectric SrBi2Ta2O9 thin films of mixed (100) and (116) orientation on SrLaGaO4(110) (2001)

Epitaxial ferroelectric SrBi2Ta2O9 (SBT) thin films with a well-defined crystallographic orientation state consisting of a mix of (100) and (116) orientations have been grown on (110)-oriented SrLaGaO4 (SLG) substrates by pulsed laser deposition. X-ray pole figure analyses revealed the presence of two epitaxial orientation relationships, viz. SBT(100)‖SLG(110); SBT[001]‖SLG[001] and SBT(116)‖SLG(110); SBT[1̄10]‖SLG[001]. By calculating the integrated intensity of certain x-ray diffraction peaks, it was established that the crystallinity and the in-plane orientation of the (100) and (116) orientation are maximized at a substrate temperature of 775 and 788 °C, respectively, and that the volume fraction of the (100) orientation at about 770 °C reached about 60%.
<title>Monitoring exocytosis with laser-induced native fluorescence: capillary electrophoresis and imaging microscopy</title> (1997)

The complex temporal evolution of exocytotic release of serotonin and proteins from individual rat peritoneal mast cells was monitored. Laser-induced native fluorescence with 275- and 305-nm excitation was used to detect the Polymyxin-B sulfate (Pmx) stimulated exocytosis in capillary electrophoresis (CE) and imaging microscopy, respectively. Events are observed that are consistent with released serotonin from single granules (250 aL each). With CE, a detection limit of 1.7 amol (S/N equals 3; rms) was obtained for serotonin. Following the injection of a cell into the capillary, electromigration of Pmx toward and past the cell induced degranulation and release of serotonin. The time course of release was registered in the electropherograms with sub-second resolution. The average amount of serotonin observed per cell was 1.6 +/- 0.6 fmol; the average percentage of serotonin released was 28 +/- 14%. In complementary experiments, exocytosis was monitored temporally and spatially using native fluorescence imagery microscopy. Real time chemical images of serotonin and protein released from individual cells are obtained. The images show that the amount of material released and the time delay of the event varied from cell to cell, and that different regions of a cell behave asynchronously in releasing material.© (1997) COPYRIGHT SPIE--The International Society for Optical Engineering.

Experimental Observation of Nonlinear Landau Damping of Plasma Waves in a Magnetic Field (1970)

Experiments on nonlinear Landau damping and growth of longitudinal plasma waves that propagate nearly perpendicular to a magnetic field have been carried out. The measured value of the nonlinear wave-particle coupling coefficient is in good agreement with theory.
Identification of Forces Transmitted onto Car Body Through Rubber Bushings in Suspension System Under Driving Conditions (1999)

&lt;div class="htmlview paragraph"&gt;This paper presents a study on using rubber bushing as a sensor for the identification of forces transmitted onto the car body. The method starts from the idea that the transmission forces can be related to the deformation of the rubber bushing multiplied by its stiffness. Deformation of the rubber bushing is estimated from relative vibrations across the bushing. Simple theories are presented to deal with modeling of the rubber bushing and processing of the vibration mesurements on the link and car body to identify the transmission forces. Then, validity of the proposed approach is shown by applications to a suspension system under several driving conditions.&lt;/div&gt;
