Towards a visual-hull based multi-agent surveillance system (2009)

We present a multi-view three dimensional intelligent surveillance system. We use a multi-agent framework to identify the behaviors of individuals in the scene. Detection and interpretation are performed completely in 3D space. A moving train coach is monitored by eight fish-eye cameras. Segmentation masks extracted from the undistorted images are fed to a distributed 3D reconstruction algorithm producing an octree-based description of the volume at each frame. Voxel-based algorithms extract connected-regions and their descriptions from consecutive models. The set of regions is mapped to a set of agents. We achieve dynamically consistent high-level interpretations by combining probabilistic models of human behaviors and intelligent reasoning.

Developing the principle of divergent coding for Gaussian channels (2018)

Mutithreshold decoding for convolutional codes implementing optimization methods to correct errors based on the search of global extremum of functionals in discrete spaces are considered. The implementation of divergent coding methods with triple concatenation to achieve highly efficient decoding near channel capacity is described. The possibilities of this approach while using concatenation are shown. Multialgorithmic decoding is offered. It implements the principle of divergence with simultaneous usage of two types of decoders: Viterbi algorithm and multithreshold decoding. The implementation of multialgorithmic decoding is shown to substantially decrease decoding complexity at low signal to noise ratio.
Bacterial nanotubes as a manifestation of cell death (2020)

Bacterial nanotubes are membranous structures that have been reported to function as conduits between cells to exchange DNA, proteins, and nutrients. Here, we investigate the morphology and formation of bacterial nanotubes using Bacillus subtilis. We show that nanotube formation is associated with stress conditions, and is highly sensitive to the cells' genetic background, growth phase, and sample preparation methods. Remarkably, nanotubes appear to be extruded exclusively from dying cells, likely as a result of biophysical forces. Their emergence is extremely fast, occurring within seconds by cannibalizing the cell membrane. Subsequent experiments reveal that cell-to-cell transfer of non-conjugative plasmids depends strictly on the competence system of the cell, and not on nanotube formation. Our study thus supports the notion that bacterial nanotubes are a post mortem phenomenon involved in cell disintegration, and are unlikely to be involved in cytoplasmic content exchange between live cells.
Fabrication of High Quality, Large Wet Lay-Up/Vacuum Bag Laminates by Sliding a Magnetic Tool (2018)

This study presents a novel method to fabricate high-quality, large composite parts which can be used in a wet lay-up/vacuum bag (WLVB) process. The new method utilizes a commercial lifting magnet, which is commonly used for transporting ferrous plates, to apply a magnetic consolidation pressure on the WLVB composite lay-up. The pressure is applied on a large area of the laminate by slowly sliding the magnet over the vacuum bag surface, which leads to an improved laminate quality. When further improvement is desirable, multiple passes of the magnet can be performed, where each pass successively compacts the lay-up. To explore the feasibility of implementing this technique, random mat and plain weave glass/epoxy laminates were fabricated, and their properties compared to conventional WLVB laminates. The effects of the number of moving passes of the lifting magnet on the laminate microstructure and properties are also investigated. As a result of multiple passes, the fiber volume fraction in random mat and plain weave laminates increases to 34% and 53%, representing 80% and 16% improvements, respectively. In addition, the void volume fraction reduces almost by 60% to a very low level of 0.7% and 1.1%, respectively. Consequently, the flexural properties considerably enhance by 20⁻81%, which demonstrates the potential of the proposed method to produce WLVB parts with substantially higher quality. It is also shown that there exists an optimal number of passes, depending on the fabric type where additional passes induce new voids as a result of excessive resin removal.
Aerosol-assisted synthesis and assembly of nanoscale building blocks (2013)

Aerosol methods, including spray drying and spray pyrolysis, represent industrial scale routes to materials on account of their continuous nature. Recently, these methods have been used to prepare size-, shape- and architecturally controlled nanostructures for a range of inorganic materials. In this Feature Article, a brief overview of traditional aerosol methods is provided. Then, the new chemical methods that have been integrated into aerosol techniques to achieve high quality nanomaterials are highlighted. Given that the properties of nanomaterials are dependent on their structural features, these synthetic advances help to address the critical need for new nanomanufacturing routes to materials.
Perilymph/Modiolar Communication Routes in the Human Cochlea (2006)

This canalicular system may play a role in the circulation of perilymph in the human cochlea. We suggest that this system may represent an important fluid communication route between modiolus and perilymph and may represent a pathway for future drug and cell-based therapy to the inner ear.

Quantifying Sound Quality in Loudspeaker Reproduction (2016)

We present PREQUEL: Perceptual Reproduction Quality Evaluation for Loudspeakers. Instead of quantifying the loudspeaker system itself, PREQUEL quantifies the overall loudspeakers' perceived sound quality by assessing their acoustic output using a set of music signals. This approach introduces a major problem: subjects cannot be provided with an acoustic reference signal and their judgment is based on an unknown, internal, reference. However, an objective perceptual assessment algorithm needs a reference signal in order to be able to predict the perceived sound quality. In this paper, these reference signals are created by making binaural recordings with a head and torso simulator, using the best quality loudspeakers, in the ideal listening spot in the best quality listening environment. The reproduced reference signal with the highest subjective quality is compared to the acoustic degraded loudspeaker output. PREQUEL is developed and, subsequently, validated, using three databases that contain binaurally recorded music fragments played over low to high quality loudspeakers in low to high quality listening rooms. The model shows a high average correlation (0.85) between objective and subjective measurements. PREQUEL thus allows prediction of the subjectively perceived sound quality of loudspeakers taking into account the influence of the listening room and the listening position.
SiO2-Modified Pt/Al2O3for Oxidative Dehydrogenation of Ethane: A Preparation Method for Improved Catalytic Stability, Ethylene Selectivity, and Coking Resistance (2018)

A SiO2-modified Pt/Al2O3 catalyst (SiO2/Pt/Al2O3) was synthesized with a solution-based method using Pt/Al2O3 as the starting catalytic material and tetraethoxysilane (TEOS) as the Si precursor. The modification process can be conducted with several cycles. Each of the modification cycles included sequentially an evacuation step at an elevated temperature and an impregnation step followed by a solution-treatment step. The introduced SiO2 layer showed an obvious sintering-resisting effect for the Pt nanoparticles at a high temperature of 600 °C. When used for catalytic oxidative dehydrogenation of ethane (ODHE), SiO2/Pt/Al2O3 presented a significantly improved catalytic stability and coking depression compared to the unmodified Pt/Al2O3. Furthermore, the introduced SiO2 layer helped improve the ethane conversion slightly and the selectivity to ethylene mildly. The improved selectivity to ethylene could be associable with the Brönsted acid sites brought by the SiO2 layer as well as site distribution of the exposed Pt surface.
Comparative performance analysis of time-frequency distributions for spectroscopic optical coherence tomography (2004)

Joint time-frequency distributions (TFDs) can optimize the tradeoff between spectral and spatial resolution in spectroscopic OCT. Performances by representative TFDs are compared and optimized for different spectroscopic OCT applications.
0.8-bit/s/Hz Terabit Transmission at 42.7-Gb/s Using Hybrid RZ-DQPSK and NRZ-DBPSK Formats over 16 x 80 km SSMF Spans and 4 Bandwidth-Managed ROADMs (2007)

We demonstrate for the first time the use of asymmetric-bandwidth interleaver based ROADM to transmit 42.7-Gb/s channels on a 50-GHz grid. Mixed DBPSK and DQPSK formats enabled 0.8-bit/s/Hz terabit transmission over 1280-km including 4 ROADMs.
Autonomic dysfunction in botulism B (1975)

Nine cases of botulism B with preponderant effects upon cholinergic autonomic innervation are presented. Blurred vision and dry mouth were constant symptoms. Impairment of salivary and lacrimal secretion were detectable for months. In the absence of clinical signs, electromyographic studies did not reveal neuromuscular involvement. Administration of antitoxin in the late course of such cases is not recommended, but guanidine can be used. Doubt is cast upon a new clinical entity called "acute autonomic neuropathy."
Status of the ERDA/NASA Photovoltaic Tests and Applications Project (1976)

The Tests and Applications Project of the ERDA Photovoltaic Program is concerned with the testing of photovoltaic systems and the growth of their use in real terrestrial applications. This activity is an important complement to the development of low cost solar arrays by providing requirements based on application needs and stimulating markets to create demand to absorb increasing production capacity. A photovoltaic system test facility is now operational, market stimulation has been initiated through applications, and standards for terrestrial cell measurements established.
Delivery and therapeutic potential of human granzyme B (2010)

Granzyme B (GzmB) is used by cytotoxic lymphocytes as a molecular weapon for the defense against virus-infected and malignantly transformed host cells. It belongs to a family of small serine proteases that are stored in secretory vesicles of killer cells. After secretion of these cytolytic granules during killer cell attack, GzmB is translocated into the cytosol of target cells with the help of the pore-forming protein perforin. GzmB has adopted similar protease specificity as caspase-8, and once delivered, it activates major executioner apoptosis pathways. Since GzmB is very effective in killing human tumor cell lines that are otherwise resistant against many cytotoxic drugs and since GzmB of human origin can be recombinantly expressed, its use as part of a 'magic bullet' in tumor therapy is a very tempting idea. In this review, we emphasize the peculiar characteristics of GzmB that make it suited for use as an effector domain in potential immunoconjugates. We discuss what is known about its uptake into target cells and the trials performed with GzmB-armed immunoconjugates, and we assess the prospects of its potential therapeutic value.

Impact of fiber core diameter on dispersion and multiplexing in multimode-fiber links (2014)

Large-core silica multimode fibers, whose core diameters are generally 50 μm or 62.5 μm, form the bulk of short and medium haul optical fiber links in existence today, owing to their low cost and ease of deployment. However, modal dispersion significantly limits the maximum data rates that they support. Recently, the ability to multiplex several streams of data through optical fibers has spawned the development of few-mode multimode fibers. These fibers possess the low-dispersion characteristics of single-mode fibers and the ability to multiplex several data streams using multiple-input multiple-output (MIMO) techniques and mode-specific filtering to increase data rates. While fibers with larger core diameters possess a larger number of spatial modes, they do not support data rates as high as few-mode fibers. In this paper, we describe a simulation based approach to characterize the tradeoffs between fiber diameter, achievable data rates and alignment tolerances of coherent links that employ graded-index multimode fibers (MMFs) of various dimensions, using the information theoretic outage capacity as the metric. The simulations used fibers' intermodal coupling characteristics to measure its multiplexing abilities and dispersion limitations with mode-specific filters and launch and detection spatial filter arrays. The simulations indicate that the bandwidth-length product achievable over few-mode fibers with MIMO techniques can exceed 250 Gb/s-km, while heavy mode spreading and limited mode selectivity limits the bandwidth-length product to under 25 Gb/s-km in fibers core diameters larger than 50 μm.
A simple and rapid antibody‐capture ELISA for the detection of staphylococcal enterotoxin A in food including a simple extraction step (1994)

A sensitive and precise ELISA for the detection of staphylococcal enterotoxin A in food has been developed, using specific IgG anti‐toxin antibodies purified from immunized rabbits. an antibody capture format was found to be the most useful following cross‐reaction and sensitivity studies. the ELISA was used to investigate concentration of staphylococcal enterotoxin A from food samples by polyethylene glycol dialysis. the procedure was shown to be inefficient and highly variable, as well as time‐consuming. Direct analysis of aqueous food extracts without a concentration step was found to be possible. With an assay time of 140 min, the ELISA detection limit was 12.5 pg of toxin (corresponding to a sensitivity of 0.5 ngg ‐1 of food sample.
Insight into Amorphous Solid Dispersion Performance by Coupled Dissolution and Membrane Mass Transfer Measurements (2018)

The tendency of highly supersaturated solutions of poorly water-soluble drugs to undergo liquid-liquid phase separation (LLPS) into drug-rich and water-rich phases when the concentration exceeds the amorphous solubility, for example, during dissolution of some amorphous solid dispersions, is thought to be advantageous from a bioavailability enhancement perspective. Recently, we have developed a high surface area, flow-through absorptive dissolution testing apparatus that enables fast mass transfer providing more in vivo relevant conditions and time frames for formulation testing. Using this apparatus, the absorption behaviors of solutions with different extents of supersaturation below and above the amorphous solubility were evaluated. In addition, simultaneous dissolution-absorption testing of amorphous solid dispersions (ASDs) with varying drug loadings and polymer types was carried out to study and distinguish the absorption behavior of ASDs that do or do not undergo LLPS. When compared with closed-compartment dissolution testing, a significant influence of the absorptive compartment on the dissolution rate of ASDs, particularly at high drug loadings, was observed. The formation of drug-rich nanodroplets, generated by both solvent-addition and ASD dissolution, resulted in a higher amount of drug transferred across the membrane. Moreover, the mass transfer was further enhanced with increasing concentration above the amorphous solubility, thereby showing correlation with an increase in the number of drug-rich particles. The importance of including an absorptive compartment in dissolution testing is highlighted in this study, enabling coupling of dissolution to membrane transport, and providing a more meaningful comparison between different formulations.
Decomposing the complexity of heart-rate variability by the multifractal–multiscale approach to detrended fluctuation analysis: an application to low-level spinal cord injury (2019)

Complexity decomposition by DFA describes autonomic alterations in HRV in low-level paraplegia better than traditional indices, probably pointing out a loss of system complexity in the sitting posture and an impaired sympatho/vagal modulation in the supine position.
F233 Oscillatory Combustion in Premixed Tubular Flame Burner with Abrupt Pipe Expansion (2015)

Experiments about change of pipe length, diameter, and combustion quantity under stoichiometric condition were conducted to clarify what kind of influence abrupt pipe expansion has on combustion oscillation in the tubular flame burner. The sound pressure was measured at the tube exit by a microphone. It is found from the experimental results that installation of pipe expansion restrain heat release oscillation including the fundamental frequency of about 400 Hz and enlarge range of stable combustion. But when pipe length is longer than a certain value, combustion oscillation is always generated regardless of combustion quantity and pipe diameter. This is why mutual sound pressure level was amplified by axial mode of columnar resonance wave and heat release oscillation.
Application of Hot-Dip Zn-6%Al-3%Mg Alloy Coated Steel Sheet to Automotive Body (2005)

<div class="htmlview paragraph">Nisshin steel has succeeded in the commercial production of a hot dip Zn-6%Al-3%Mg alloy coated steel sheet (ZAM) produced by continuous galvanizing. ZAM has a coating layer containing high content of Mg and so it has good bare corrosion resistance. The purpose of this paper is to show results from investigations aimed at evaluating ZAM for application in automotive body panels. Through tests for paintability, corrosion resistance, spot weldability and press formability, it is confirmed that ZAM shows good performance. This is especially true in terms of cosmetic and perforation corrosion resistance, when its performance is compared with that of galvanized (GI), electrogalvanized (EG) and galvanneal (GA) which are currently used in automotive bodies.</div>
Pharmacokinetics and adverse reactions of a new liposomal cisplatin (Lipoplatin): Phase I study (2005)

Lipoplatin, a new liposomal cisplatin formulation, is formed from cisplatin and liposomes composed of dipalmitoyl phosphatidyl glycerol (DPPG), soy phosphatidyl choline (SPC-3), cholesterol and methoxy-polyethylene glycol-distearoyl phosphatidylethanolamine (mPEG2000-DSPE). Following intravenous infusion, the nanoparticles (110 nm) are distributed into tissues and concentrate preferentially at tumor sites supposedly via extravasation through the leaky tumor vasculature. This study was designed to investigate the pharmacokinetics and the toxicity of this new liposomal cisplatin in patients with pretreated advanced malignant tumors. The drug was infused for 8 h every 14 days at escalating doses. Twenty-seven patients were included and 3-5 patients were selected for each dosage level; levels started at 25 mg/m2 and were increased by 25 to 125 mg/m2. Three patients were also treated at higher dose levels, one each at 200, 250 and 300 mg/m2. Blood was taken at certain time intervals in order to estimate total platinum plasma levels. At level 5 (125 mg/m2), grades 1 and 2 GI tract and hematological toxicities were detected. No nephrotoxicity was observed. Seven additional patients were added at the 4th level (100 mg/m2) for further pharmacokinetic evaluation. Measurement of platinum levels in the plasma of patients as a function of time showed that a maximum platinum level is attained at 6-8 h. The half-life of Lipoplatin was 60-117 h depending on the dose. Urine excretion reached about 40% of the infused dose in 3 days. The data demonstrate that Lipoplatin up to a dose of 125 mg/m2 every 14 days has no nephrotoxicity and it lacks the serious side effects of cisplatin.
Robust static output feedback stabilization of discrete-time nonlinear uncertain systems with H<inf>&#x221E;</inf> performance (2008)

A new approach for the design of robust static output feedback controller for a class of discrete-time Lipschitz nonlinear systems with time-varying uncertainties is proposed based on linear matrix inequalities. The controller has also a guaranteed disturbance attenuation level (H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">infin</sub> performance). Thanks to the linearity of the proposed LMIs in both the admissible Lipschitz constant of the system and the disturbance attenuation level, they can be simultaneously optimized through convex multiobjective optimization. The optimization over Lipschitz constant adds an extra important and new feature to the controller, robustness against nonlinear uncertainty. The resulting controller is robust against both nonlinear additive uncertainty and time-varying parametric uncertainties. Explicit norm-wise and element-wise bounds on the tolerable nonlinear uncertainty are derived.
