Cars detection and tracking with a vision sensor (2004)

In this article, a visual sensor combining a short fixed focal length camera and a PTZ (Pan Tilt Zoom) camera is described. The works presented here deal with process for cars detection and tracking using this vision sensor. These algorithms have been tested in real driving situations with a PC embedded into the experimental vehicle of the laboratory named VELAC. Front vehicles can be detected and tracked up to 140 meters with our sensor.

Thermal Decomposition Reaction Kinetics of Hematite Ore (2019)

In order to understand the thermal decomposition kinetics of hematite particles in inert atmosphere, thermogravimetriy was employed for isoconversional analysis. The kinetic triplet was estimated from the experimental data and the isothermal reaction kinetics was predicted. The results indicated that the thermal decomposition could be divided into two stages, of which the activation energies were 636 kJ/mol and 325 kJ/mol, respectively. The exponential form of pre-exponential factor, ln(A/s−1), for the two stages were estimated to be 42.9±6.6 and 14.1±3.08. At last, the kinetic mechanism of the first stage was suggested to match Sestak-Berggren model as f(α)=(1−α)1.38. The relatively slow reaction rate of the second stage was due to the slag formation during the reaction.
Automatic pool allocation for disjoint data structures (2002)

This paper presents an analysis technique and a novel program transformation that can enable powerful optimizations for entire linked data structures. The fully automatic transformation converts ordinary programs to use pool (aka region) allocation for heap-based data structures. The transformation relies on an efficient link-time interprocedural analysis to identify disjoint data structures in the program, to check whether these data structures are accessed in a type-safe manner, and to construct a Disjoint Data Structure Graph that describes the connectivity pattern within such structures. We present preliminary experimental results showing that the data structure analysis and pool allocation are effective for a set of pointer intensive programs in the Olden benchmark suite. To illustrate the optimizations that can be enabled by these techniques, we describe a novel pointer compression transformation and briefly discuss several other optimization possibilities for linked data structures.
Comparison of commercial membranes in nanofiltration of sweet whey (2002)

The performance of commercial nanofiltration membranes was studied during concentration and demineralization of sweet whey. The tested membranes were Desal-5 DK, NF45 and Koch SR1. Two different generations of the NF45 membranes were studied. Concentration of whey was made both with a flat-sheet module and in a pilot plant equipped with one spiral wound element. The new generation of the NF45 membrane has comparable retention characteristics with the Desal-5 DK. The Koch SR1 membrane has lower salt and lactose retention than the Desal-5 DK and similar retention characteristics to the older generation of the NF45, which is no longer commercially available. When using the new generation of the NF45 membrane one can expect lower permeate flux and higher retention of salts and lactose than before with the older generation of the NF45 membrane. The highest permeate fluxes of the tested membranes were reached with the Koch SR1 membrane. Concentration of sweet whey with a flat-sheet module and a spiral wound element resulted in similar concentrate composition. Therefore, the flat-sheet module may be used when information on product composition is being investigated. The permeate flux was higher with the flat-sheet module than with the spiral wound element. Thus, either the spiral wound module is more prone to concentration polarization than the flat-sheet module or one can assume that the whole membrane area of the spiral wound module is not used effectively.
Endoscopic-Assisted Transorbital, Transethmoid, Trans-sphenoid Approach for Optic Nerve Decompression (2007)

Introduction: Surgical decompression of the optic canal is warranted in several forms of optic nerve compression. This study describes the trans-orbital, trans-ethmoidal, trans-sphenoidal endoscopic assisted route for optic nerve decompression and compares it with that of the endonasal trans-sphenoidal route in terms of the ease of identifying the vital landmarks in the lateral wall of the sphenoid sinus. Furthermore, how far posteriorly the extent of decompression should be carried out is also described.

Site-selective doping of ordered charge states in magnetite (2020)

Charge ordering creates a spontaneous array of differently charged ions and is associated with electronic phenomena such as superconductivity, colossal magnetoresistances (CMR), and multiferroicity. Charge orders are usually suppressed by chemical doping and site selective doping of a charge ordered array has not previously been demonstrated. Here we show that selective oxidation of one out of eight distinct Fe<sup>2+</sup> sites occurs within the complex Fe<sup>2+</sup>/Fe<sup>3+</sup> ordered structure of 2%-doped magnetite (Fe<sub>3</sub>O<sub>4</sub>), while the rest of the charge and orbitally ordered network remains intact. This 'charge order within a charge order' is attributed to the relative instability of the trimeron distortion surrounding the selected site. Our discovery suggests that similar complex charge ordered arrays could be used to provide surface sites for selective redox reactions, or for storing information by doping specific sites.
Combined smart chemFET/resistive sensor array (2004)

Here we describe a novel CMOS compatible gas sensor array based on a combined resistive/chemFET sensor cell. We have fabricated an array of 70 sensors with integrated drive, gain and baseline removal circuitry using an AMS 0.6 /spl mu/m CMOS process. The sensing materials are carbon black/polymer composite (CB) thin films, which have been previously reported to have good vapour-sensing properties. Different CB films have been deposited onto the sensor array and have been shown to respond differently to volatile organic compounds. This combined sensing element both reduces silicon area and, more importantly, measures different physical properties of the same gas sensitive material improving discrimination and giving more insight into the sensing mechanism.
PHOTIC SIGNALING IN THE FIREFLY<i>PHOTINUS GREENI</i> (1972)

1. In duplicating the courtship signals of Photinus greeni it was found possible to substitute flashes of artificial light for either the male or the female. 2. In confirmation of previous work, the courtship signals of P. greeni were found to depend on the female's recognition of the male's stimulus signal of two flashes and the male's recognition of the female's fixed response interval after his second flash. At 27° C the acceptance limits of the male's phrase were from about 1.1 to 1.7 seconds and the limits of the female's response latency were from about 0.8 to 1.1 seconds. 3. Within wide limits the delivery rate of the male's two-flash signal ("phrase"), and the intensities, durations and source areas of the flashes of male and female, are immaterial to the success of the signaling. 4. The two flashes of the male's stimulus phrase can be made multiple, or increased several-fold in duration, without preventing the female from responding, as long as the proper time relation between the starts of the first flash and one subsequent one is preserved. From this it is concluded that it is the rise in light intensity that is perceived by the female and that she is refractory to new visual input for several hundred milliseconds after being stimulated. 5. Instances in which males fell into step with torch flashes being used to stimulate females serially are interpreted as male-male communication. 6. It is concluded tentatively that the female times her response latency from the second flash of the male's stimulus phrase. 7. The behavioristic data for the Cape Cod P. greeni are consistent with its belonging to the same species as the Florida strain and with being distinct from P. consanguineus and P. macdermotti.

Protein-based optical transducer for mechatronic devices (2001)

An optical transducer based on the light modulated transmission properties of bacteriorhodopsin (bR) film is described in this paper. The bR protein molecules undergo a complex photocycle when absorbing light energy that is characterized by several measurable states. The most relevant states in the photocycle for this application are the initial B state (λ<sub>max</sub>= 570 nm) and the longest lived M intermediate state (λ<sub>max</sub>= 410 nm). If a yellow light source with a wavelength of approximately 570 nm and a second deep blue source at 410 nm illuminate the same region of the thin bR film, the two beams will mutually suppress the optical transmission properties of the thin film and reduce the intensity of the light output. The suppression-modulated transmission mechanism of the bR polymeric film is, therefore, controlled by the intensity and wavelength of the two light sources. Based on this simple mechanism, a number of different protein-based optical devices have been proposed in the literature for optical signal and information processing. The focus of this research is to exploit the light transmission properties of the bR film to develop efficient optical transducers that can be easily interfaced with micro-electro-mechanical systems for mechatronic applications. The proposed transducer design is activated by an external light source and free from electrical noise. Illustrations of how thin bR film can be used for the modulation of light intensity, optical switches, and logic gates are presented.

A 1-V transient-free and DC-offset-canceled PGA with a 17.1-MHz constant bandwidth over 52-dB control range in 0.35-&#x03BC;m (2006)

Two circuit techniques, namely switched-current-resistor (SCR) and switchable DC-offset canceler (S-OC) inside opamp, are proposed to realize a low-voltage, transient-free and constant-bandwidth programmable-gain amplifier (PGA) with also adaptive stage-DC-offset cancellation. Fabricated in 0.35-/spl mu/m CMOS, the PGA dissipates 7.4mW from 1V. The mean and standard deviation of the bandwidth over 52-dB gain range are 17.1 MHz and 8.3%, respectively. The SFDR is 56.2dB. The transient in a 52-dB-gain step settles within 0.2/spl mu/s.

In-Hospital and 1-Year Mortality Associated with Diabetes in Patients with Acute Heart Failure: Results from the ESC-HFA Heart Failure Long-Term Registry (2016)

Among patients hospitalized for acute HF, the presence of diabetes is independently associated with an increased risk of in-hospital mortality, 1-year all-cause mortality, and 1-year re-hospitalizations for HF, underscoring the need for more effective and personalized treatments of diabetes in this particularly high-risk patient population.
Cover Feature: Lewis Base Catalysis Promoted Nucleophilic Substitutions – Recent Advances and Future Directions (Eur. J. Org. Chem. 1/2020) (2019)

The Cover Feature shows Lewis base catalyzed nucleophilic substitutions (SN) engaging non-activated alcohols, carboxylic acids, aldehydes, and epoxides as substrates. In fact, SN-transformations are of fundamental significance in chemistry. Especially in the last decade, powerful catalytic approaches for SN-type C–C, C–N, C–O, and C–Cl bond formations have been implemented. The current review outlines modern concepts for catalytic SN-conversions and details novel Lewis base promoted methods. More information can be found in the Minireview by P. H. Huy et al.
Plasmid-Mediated 16S rRNA Methylases among Extended-Spectrum β-Lactamase-Producing <i>Enterobacteriaceae</i> Isolates (2008)

Plasmid-Mediated 16S rRNA Methylases among Extended-Spectrum␤-Lactamase-Producing Enterobacteriaceae Isolates ᰔ High levels of resistance to aminoglycosides conferred by plasmid-mediated mechanisms of resistance to aminoglycosides corresponding to 16S rRNA methylases have been reported since 2003 (3, 11).To date, six enzymes (ArmA, RmtA, RmtB, RmtC, RmtD, and NpmA) have been described, with ArmA being the most frequently identified methylase in Enterobacteriaceae (2).Associations between 16S rRNA methylase-and extended-spectrum ␤-lactamase (ESBL)-encoding genes such as the bla CTX-M genes have been reported (1,7,8).The aim of this study was to evaluate the prevalence of 16S rRNA methylase genes among ESBL-producing Enterobacteriaceae isolates recovered in a French university hospital.A total of 373 nonduplicate ESBL-producing enterobacterial clinical isolates, collected at the Bice ˆtre hospital between January 2005 and December 2007, have been studied.Among them, 19 isolates (5.1%) were resistant to all clinically used aminoglycosides.That collection was screened by PCR for detection of 16S rRNA methylase-encoding genes (armA, rmtA, rmtB, rmtC, rmtD, and npmA), as previously described (2).Four armA-positive isolates were detected in 2005 (n ϭ 2) and in 2007 (n ϭ 2), in addition to a single rmtB-positive isolate from 2006.No isolate was positive for the rmtA, rmtC, rmtD, and npmA genes.The armA-positive isolates produced the ESBL CTX-M-3 (n ϭ 3) or CTX-M-14 (n ϭ 1), whereas the single rmtB-positive isolate was a CTX-M-14 producer.(CTX-M enzymes were searched for as described previously [6].)The low prevalence rate of 16S rRNA methylase determinants among ESBL producers (1.3%) observed here is similar to that reported from Taiwan (1.1%) (8) and higher than

Cover Feature: Synthesis and Biological Evaluation of Stilbene Analogues as Hsp90 C‐Terminal Inhibitors (ChemMedChem 24/2017) (2017)

The Cover Feature reveals heat shock protein 90 (Hsp90) in an animated complex with client protein substrates that represent therapeutically sought after oncogenic targets. When an inhibitor of appropriate size and shape binds Hsp90, the protein folding machinery is disrupted and the client proteins degraded. This work focused on the elucidation of structure–activity relationships for the recently disclosed stilbene-based Hsp90 inhibitors. Compounds with a triazole-containing amide side chain, tertiary amine, and an overall length of ∼24 Å manifested low nanomolar antiproliferative activity that results from Hsp90 inhibition.

Quantum Optical Studies of Tunneling and other SuperluminalPhenomena (1998)

Experiments at Berkeley and elsewhere which show that the process of tunneling is apparently superluminal will be reviewed. Conflicting theories for the tunneling time will be compared with experiment. The tunneling particle in the Berkeley experiments was the photon. The measurement of the tunneling time utilized a two-photon light source (spontaneous parametric down-conversion), a Hong-Ou-Mandel interferometer, and a coincidence counter of photon pairs. The tunnel barrier consisted of a photonic-bandgap medium excited at midgap. We find that the peak of a tunneling single-photon wave packet appeared on the far side of the barrier 1.47 ± 0.21 fs earlier than the peak of a wave packet which traveled an equal distance in air. Group velocities which exceed c can also occur in transparent media with inverted atomic populations. Tachyon-like excitations, i.e., collective normal modes of atoms coupled to electromagnetic radiation which possess tachyon-like dispersion relations, occur in these media. However, relativistic causality is not violated by any of these superluminal phenomena.
Cardiovascular structural and functional maturation (1993)

Cardiovascular defects represent the largest cause of childhood mortality. Of the 25,000 infants diagnosed with cardiovascular abnormalities each year, 5000 (20%) of those infants will die in the first year of life despite the best medical care. Thus, the broad spectrum of research to define cardiovascular structural and functional maturation includes human embryo, fetal, and neonatal studies, as well as experiments using animal, organ, cell, and subcellular protocols in chick embryo, rat, rabbit, dog, pig, and lamb models. New information further details the maturation of myocyte sarcolemmal and sarcoplasmic calcium transport, the composition of the regulatory thin filament, and the distribution of α-actins, β-myosins, and components of the extracellular matrix in the developing and diseased heart. Coronary angiogenesis in the developing and hypertrophied myocardium is more uniform than found in the mature heart. New quantitative data are available on myocardial growth in the embryonic and neonatal myocardium, and following heart transplantation. Investigation of embryonic, fetal, and neonatal cardiovascular function further highlights the dynamic interdependence of the maturing heart and systemic and pulmonary vascular beds. Exciting information continues to accumulate on the role of the endothelium in the regulation of pulmonary vascular tone.

Magnetic Field Effects on Plasma Plumes (2012)

Here, we will discuss our numerical studies of plasma jets and loops, of basic interest for plasma propulsion and plasma astrophysics. Space plasma propulsion systems require strong guiding magnetic fields known as magnetic nozzles to control plasma flow and produce thrust. Propulsion methods currently being developed that require magnetic nozzles include the VAriable Specific Impulse Magnetoplasma Rocket (VASIMR) [1] and magnetoplasmadynamic thrusters. Magnetic nozzles are functionally similar to de Laval nozzles, but are inherently more complex due to electromagnetic field interactions. The two crucial physical phenomenon are thrust production and plasma detachment. Thrust production encompasses the energy conversion within the nozzle and momentum transfer to a spacecraft. Plasma detachment through magnetic reconnection addresses the problem of the fluid separating efficiently from the magnetic field lines to produce maximum thrust. Plasma jets similar to those of VASIMR will be studied with particular interest in dual jet configurations, which begin as a plasma loops between two nozzles. This research strives to fulfill a need for computational study of these systems and should culminate with a greater understanding of the crucial physics of magnetic nozzles with dual jet plasma thrusters, as well as astrophysics problems such as magnetic reconnection and dynamics of coronal loops.[2] To study this problem a novel, hybrid kinetic theory and single fluid magnetohydrodynamic (MHD) solver known as the Magneto-Gas Kinetic Method is used.[3] The solver is comprised of a "hydrodynamic" portion based on the Gas Kinetic Method and a "magnetic" portion that accounts for the electromagnetic behaviour of the fluid through source terms based on the resistive MHD equations. This method is being further developed to include additional physics such as the Hall effect. Here, we will discuss the current level of code development, as well as numerical simulation results
