Object detection and localization in compressed video (2001)

We study the problem of detecting and localizing objects that are embedded in compressed video sequences. Such a capability has two major and increasingly important practical uses: (1) video surveillance; (2) identification of copyright infringement. We focus here only on the problem of video surveillance. As a general rule, detection and localization of patterns is most efficiently performed in a reduced-dimensional subspace of the original object space. In this regard, it would be ideal to operate directly on the compressed bit stream. As a first step towards doing this, we consider here the problem of detecting and localizing video objects in the DCT domain (i.e., after the quantized DCT coefficients have been decoded but before the inverse DCT has been applied). We present comparisons between this DCT-based approach and the more conventional method in which object detection and localization is performed entirely in the spatial domain.
How many general and inflammatory variables need to be fulfilled when defining sepsis due to the 2003 SCCM/ESICM/ACCP/ATS/SIS definitions in critically ill surgical patients: a retrospective observational study (2010)

Frequencies and mortality rates of diagnostic categories of sepsis differ depending on the cut-off for general and inflammatory variables. A cut-off of 3/8 variables is needed to identify almost all patients with septic shock who may benefit from optimal treatment.
Human silhouette extraction on FPGAs for infrared night vision military surveillance (2010)

Infrared visual surveillance has become an important mean to secure military camps, reassure soldier security, and detect suspected terror activities in the battle fields. An intelligent infrared surveillance system is aimed to provide real-time intelligent analysis of the perceived scene and find out human targets instantly to assist the soldier/commanders to make the right decision in a just-in-time mode to save our soldiers from life risks. To attain this, automatic detection of moving human objects from the scene is an essential step. In this paper, we present an FPGAs-based architecture to perform on-chip human silhouette extraction using a parallel architecture with systolic arrays. The architecture is designed in VHDL and simulated with real FLIR videos. The experiment shows that the designed processor on FPGAs can efficiently extract the human contour instantly from infrared videos, which exhibits great potential to facilitate the further analysis of the battlefield scenes for military-purpose surveillance systems.
Three-Dimensional Paper-Based Microfluidic Analytical Devices Integrated with a Plasma Separation Membrane for the Detection of Biomarkers in Whole Blood (2019)

Paper-based microfluidic analytical devices (μPADs) have recently attracted attention as a point-of-care test kit because of their low cost and nonrequirement for external forces. To directly detect biomarkers in whole blood, however, they need to be assembled with a filter such as a plasma separation membrane (PSM) because the color of the blood cells interferes with the colorimetric assay. However, this assembly process is rather complicated and cumbersome, and the fluid does not uniformly move to the detection zone when the adhesion between the paper and PSM is not perfect. In this study, we report a simple three-dimensional (3D) printing method for fabricating PSM-integrated 3D-μPADs made of plastics without the need for additional assembly. In detail, PSM was coated with parylene C to prevent its dissolution from organic solvent during 3D printing. Then, the coated PSM was superimposed on the paper. Detection zones and a reservoir were printed on the paper and PSM via liquid photopolymerization, using a digital light processing printer. The limit of detection of the PSM-integrated 3D-μPADs for glucose in whole blood was 0.3 mM, and these devices demonstrated clinically relevant performance on diabetes patient blood samples. Our 3D-μPADs can also simultaneously detect multiple metabolic disease markers including glucose, cholesterol, and triglycerides in whole blood. Our results suggest that our printing method is useful for fabricating 3D-μPADs integrated with PSM for the direct detection of biomarkers in whole blood.
Function minimization and automatic differentiation using C++ (1989)

Function minimization techniques often require values for the first partial derivatives of the function at a point. Certain techniques, such as Newton's method, require the values of the second partial derivatives as well. The methods commonly used to obtain these values have certain drawbacks which can be eliminated using a technique known as automatic differentiation. When this technique is implemented in an object oriented language with operator overloading capabilities, the problem of differentiation and minimization can be mapped into a code which fits well with the problem space.
Development of a strong Goss texture during annealing of a heavily rolled Al—0.3% Cu alloy (2015)

The evolution of microstructure and texture during isochronal annealing of a heavily cold rolled Al-0.3%Cu alloy has been characterized using electron backscatter diffraction.It is found that the rolling texture of this alloy is dominated by the Brass component and that recrystallization during annealing leads to the formation of a pronounced Goss texture.It is suggested that the development of the strong Goss texture in Al-0.3%Cu is caused by preferred growth of Goss-oriented grains into the Brass-oriented matrix.
Microfluidic electromanipulation with capacitive detection for the mechanical analysis of cells (2008)

The mechanical behavior of cells offers insight into many aspects of their properties. We propose an approach to the mechanical analysis of cells that uses a combination of electromanipulation for stimulus and capacitance for sensing. To demonstrate this approach, polystyrene spheres and yeast cells flowing in a 25 mumx100 mum microfluidic channel were detected by a perpendicular pair of gold thin film electrodes in the channel, spaced 25 mum apart. The presence of cells was detected by capacitance changes between the gold electrodes. The capacitance sensor was a resonant coaxial radio frequency cavity (2.3 GHz) coupled to the electrodes. The presence of yeast cells (Saccharomyces cerevisiae) and polystyrene spheres resulted in capacitance changes of approximately 10 and 100 attoFarad (aF), respectively, with an achieved capacitance resolution of less than 2 aF in a 30 Hz bandwidth. The resolution is better than previously reported in the literature, and the capacitance changes are in agreement with values estimated by finite element simulations. Yeast cells were trapped using dielectrophoretic forces by applying a 3 V signal at 1 MHz between the electrodes. After trapping, the cells were displaced using amplitude and frequency modulated voltages to produce modulated dielectrophoretic forces. Repetitive displacement and relaxation of these cells was observed using both capacitance and video microscopy.
Local fields at the surface of noble-metal microspheres (1981)

Enhancement of the Raman scattering and fluorescence emission on noble metals (Ag, Cu, and Au) is believed to be caused in part by large local fields at the incident wavelength on the surface of metallic microstructures, such as colloidal suspensions and surface roughness on electrodes and thin films. For metallic spheres immersed in water, calculations are made of the integrated near-field intensity efficiency (${Q}_{\mathrm{NF}}$) and that part associated only with the radial field component as a function of incident wavelength (200- 1200 nm) and sphere radius (0- 300 nm) which exceeds the usual Rayleigh limit and extends well into the Lorenz-Mie region. The calculated wavelength and radius dependencies of ${\mathrm{Q}}_{\mathrm{NF}}$ are compared with those for the better-known efficiencies: extinction (${Q}_{\mathrm{E}}$), far-field scattering (${Q}_{\ifmmode\cdot\else\textperiodcentered\fi{}\mathrm{sca}}$), and absorption (${Q}_{\mathrm{abs}}$). The peak values of these efficiencies have been evaluated when the incident wavelength is in resonance with dipolar and multipolar surface-plasmon modes of Ag, Cu, and Au spheres of varying radii immersed in water.
Spatial interpolation of the atmospheric water vapor content between sites in a ground‐based GPS Network (1998)

We have studied three methods of spatially interpolating GPS‐estimated wet delay time series. Five months of data from three sites in the Swedish continuously operating GPS network were used for interpolation to a fourth site. Different geometries were used, resulting in interpolation distances of 40–120 km. To assess the quality of the interpolations we compared the obtained time series with estimated wet delay from a GPS station and with radiosonde data. A method based on the theory of atmospheric turbulence showed the lowest errors when compared to both the GPS estimates and the radiosonde data. The rms errors using this method are typically 1 cm.
Impact of surface recombination on efficiency of III‐nitride light‐emitting diodes (2016)

The paper considers surface recombination at the free active region surface as the mechanism of carrier losses which has not yet been discussed with regard to III‐nitride LEDs despite of its evident importance for AlGaInP‐based light emitters. Using advanced thin‐film and triangular volumetric chip designs reported in literature as prototypes, we have demonstrated by simulation a noticeable impact of surface recombination on the wall‐plug efficiency of InGaN‐based LEDs. Various types of LEDs whose efficiency may be especially affected by surface recombination are discussed. (© 2016 WILEY‐VCH Verlag GmbH &amp;Co. KGaA, Weinheim)

Recognition and Removal of Apoptotic Cells (2014)

This chapter discusses the recognition of apoptotic cells by phagocytes, the mechanisms of apoptotic cell phagocytosis (efferocytosis), and some of the consequences of this recognition. It illustrates, with a few nonexhaustive examples, some of the possibilities for contribution of apoptotic cell recognition and/or its mechanisms to host-parasite interrelationships. In viable cells, phosphatidylserine (PS) is generally located on the inner leaflet of the plasma membrane, which is also enriched for phosphatidylethanolamine, whereas sphingomyelin is localized to the outer leaflet along with most of the phosphatidylcholine (PC). Under certain circumstances, activation of cells leads to increased flip-flop and, as a consequence, exposure of PS. Recent studies have implicated calreticulin as a ligand on apoptotic cells that can be recognized and contributes to their removal. The possibility that thrombospondin (TSP) can act as a glue to hold everything together is intriguing. The key feature of apoptotic cell removal is the ability of phagocytes to distinguish between living versus apoptosing, or dying, cells. The general conclusion from this discussion of receptors and bridge molecules is that recognition of apoptotic cells is a highly redundant process. Much work has been carried out on the signal pathways involved in uptake of apoptotic cells. The authors present a few examples to illustrate the potential for, and to raise questions about, other possible interactions between parasites and apoptotic cell recognition, ingestion, and consequences.
A Convenient Synthesis of 1,3,2-Benzodiazaphophorine-2-oxide (2014)

The reaction of amidines 1 with hexamethylphosphoric triamide in refluxing toluene is described as a simple and efficient method for the synthesis of 1,3,2-diazaphosphorine-2-oxide derivatives 3. The structures of all the synthesized compounds have been established by NMR (1H, 13C, 31P) and IR spectroscopy, as well as by elemental analysis and in the case of 3d by MS spectral data.
Enhanced Automatic Generation Control (E-AGC) for Electric Power Systems with Large Intermittent Renewable Energy Sources (2019)

This paper is motivated by the need to enhance today's Automatic Generation Control (AGC) for ensuring high quality frequency response in the changing electric power systems. Renewable energy sources, if not controlled carefully, create persistent fast and often large oscillations in their electric power outputs. A sufficiently detailed dynamical model of the interconnected system which captures the effects of fast nonlinear disturbances created by the renewable energy resources is derived for the first time. Consequently, the real power flow interarea oscillations and the resulting frequency deviations are modeled. The modeling is multi-layered, and the dynamics of each layer (component level (generator); control area (control balancing authority), and the interconnected system) is expressed in terms of internal states and the interaction variables (IntV) between the layers and within the layers. E-AGC is then derived using this model to show how these interarea oscillations can be canceled. Simulation studies are carried out on a 5-bus system.
Polymeric ligands IV.1 Polyvinyl β‐ketoesters (1963)

Abstract Copolymers were prepared by ester interchange of polyvinylalcohol with ethyl acetoacetate, ethyl benzoylacetate, and ethyl 4‐nitrobenzoylacetate. Reaction of ethyl 2,4,6‐trimethylbenzoylacetate with polyvinylalcohol yielded a homopolymer. The polymers functioned as chelate ion exchangers. Ion exchange capacities were determined for the polymer derived from polyvinylalcohol and ethyl acetoacetate.

Emerging drugs for acute myocardial infarction (2010)

In their daily practice, cardiologists cannot abstract from the knowledge and updating on the ongoing research fields as well as the newly developed drugs, which they should frame in the very patient in the attempt to the develop a personalized medical strategy. These include also the pharmacological option(s) in the treatment of the reperfusion injury, the metabolic aspects and the stem cell therapy. TAKE HOME MASSAGE: In our opinion, the goal of ongoing research on the pharmacological approach to STEMI patients is a personalized medical strategy that relies on critical clinicians who merge newly developed acquisitions on this topic and a more complete, systemic and critical approach to the patient.
Water‐Insensitive Electron Transport and Photoactive Layers for Improved Underwater Stability of Organic Photovoltaics (Adv. Funct. Mater. 40/2022) (2022)

Organic Photovoltaics In article number 2203487, Chieh-Ting Lin, Chu-Chen Chueh, and co-workers systematically investigate the water-immersion stability among a series of organic donors/acceptors and electron transporting layers. This work presents a strategy to develop water-insensitive organic photovoltaics by combining the use of a nanoparticle titanium dioxide electron transporting layer and all-polymer bulk heterojunction blends, which shows stable morphology and charge transfer kinetics after water immersion.
Computation of group delay from attenuation characteristics via Hilbert transformation and spline function and its application to filter design (1975)

In this paper a method is described to compute the group delay of a minimum phase network from the attenuation characteristic via Hilbert transformation and spline function. The passband distortion due to dissipative loss can also be obtained with minimum amount of computation. The new approach eliminates all the numerical problems encountered in earlier attempts by many authors. As a result of its accuracy, the method can be profitably applied to assist the design of filters. An example is given to show the application and the numerical results of the method.

This paper presents a haptic rendering method for the elastic object using non-linear prediction of the finger-tip position. Using the non-linear prediction of the finger-tip position, the delay of the response in canceled.
Machine Learning Assisted Handheld Confocal Raman Micro-Spectroscopy for Identification of Clinically Relevant Atopic Eczema Biomarkers (2022)

Atopic dermatitis (AD) is a common chronic inflammatory skin dermatosis condition due to skin barrier dysfunction that causes itchy, red, swollen, and cracked skin. Currently, AD severity clinical scores are subjected to intra- and inter-observer differences. There is a need for an objective scoring method that is sensitive to skin barrier differences. The aim of this study was to evaluate the relevant skin chemical biomarkers in AD patients. We used confocal Raman micro-spectroscopy and advanced machine learning methods as means to classify eczema patients and healthy controls with sufficient sensitivity and specificity. Raman spectra at different skin depths were acquired from subjects' lower volar forearm location using an in-house developed handheld confocal Raman micro-spectroscopy system. The Raman spectra corresponding to the skin surface from all the subjects were further analyzed through partial least squares discriminant analysis, a binary classification model allowing the classification between eczema and healthy subjects with a sensitivity and specificity of 0.94 and 0.85, respectively, using stratified K-fold (K = 10) cross-validation. The variable importance in the projection score from the partial least squares discriminant analysis classification model further elucidated the role of important stratum corneum proteins and lipids in distinguishing two subject groups.
Tuftsin, A Natural Activator of Phagocyte Cells: An Overviewa (1983)

The recognition that a small oligopeptide was responsible for the full stimulation effect of specific cytophilic gamma-globulin on blood neutrophils arose from a study of the kinetics of phagocytosis. These were unusual in that the stimulation was short lived and that preincubation of the phagocyte with the gamma-globulin rendered the latter inactive. The oligopeptide was isolated, its structure determined (Thr-Lys-Pro-Arg) and synthesized. The discovery of human mutants with tuftsin deficiency exhibiting signs and symptoms of frequent severe infection further emphasized the specific biological function of the tetrapeptide. The mutant peptide was isolated, sequenced (Thr-Glu-Pro-Arg), and synthesized. Further studies showed that tuftsin requires two enzymes for its liberation from the parent carrier gamma-globulin. One enzyme is in the spleen that cleaves distal to the arginine end, and the other, on the outer side of the plasma membrane, cleaves proximal to the threonine residue. The tetrapeptide tuftsin stimulates all functions of phagocytic cells: phagocytosis, pinocytosis, motility, immunogenic activity including processing of the antigen and augmentation of the number of antibody-forming cells, bactericidal activity, and, above all, tumoricidal activity. The latter has been shown by several laboratories.
Open Label Trial of Coenzyme Q10 as A Migraine Preventive (2002)

The objective was to assess the efficacy of coenzyme Q10 as a preventive treatment for migraine headaches. Thirty-two patients (26 women, 6 men) with a history of episodic migraine with or without aura were treated with coenzyme Q10 at a dose of 150 mg per day. Thirty-one of 32 patients completed the study; 61.3% of patients had a greater than 50% reduction in number of days with migraine headache. The average number of days with migraine during the baseline period was 7.34 and this decreased to 2.95 after 3 months of therapy, which was a statistically significant response (P < 0.0001). Mean reduction in migraine frequency after 1 month of treatment was 13.1% and this increased to 55.3% by the end of 3 months. Mean migraine attack frequency was 4.85 during the baseline period and this decreased to 2.81 attacks by the end of the study period, which was a statistically significant response (P < 0.001). There were no side-effects noted with coenzyme Q10. From this open label investigation coenzyme Q10 appears to be a good migraine preventive. Placebo-controlled trials are now necessary to determine the true efficacy of coenzyme Q10 in migraine prevention.

BETO 2021 Peer Review - Enzyme Engineering and Optimization (EEO) (2021)

The FY2020 SOT economic model for the DMR BDO process indicates that the production and use of biomass degrading enzymes represents ~10% of the MFSP of BDO. We are thus working to enhance the performance of the dominant cellulase enzyme, Cel7A. In Fy2018-19, we selected 100 promising genes from the "Cel7A wheel of life" and cloned them into T. reesei using a constitutive promotor. This natural diversity screening resulted in the discovery of several enzymes exhibiting improved characteristics relative to the industry standard Cel7A from T. reesei (Tr). Growth of the transformed host on glucose insured that the Cre1 induced cellulase expression cascade was suppressed, thus enabling purification of the target gene product. The first top performing enzyme found was from P. funiculosum (Pf). Other top performing enzymes were identified from T. aculeatus, T. terrestris, and A. oryzae. Computational modeling predicted the structural subsites responsible for the improvements, which were cloned into the sequence of PfCel7A. The recombinant enzymes were expressed in T. reesei, purified, and tested. Testing was not possible with SOT relevant substrates, so the best-case substrate was used; solids from the DMR process subjected to a novel dilute alkaline wash to remove the "lignin shield." Two chimeric Cel7A enzymes show improved performance (1.2 to 1.35x) relative to PfCel7A, which in turn showed considerable improvement (1.6x) relative to T. reesei Cel7A. These new enzymes have been provided to our industrial partner for evaluation.
