A Multi-Camera System for a Real-Time Pose Estimation (2007)

This paper presents a multi-camera system that performs face detection and pose estimation in real-time and may be used for intelligent computing within a visual sensor network for surveillance or humancomputer interaction. The system consists of a Scene View Camera (SVC), which operates at a fixed zoom level, and an Object View Camera (OVC), which continuously adjusts its zoom level to match objects of interest. The SVC is set to survey the whole filed of view. Once a region has been identified by the SVC as a potential object of interest, e.g. a face, the OVC zooms in to locate specific features. In this system, face candidate regions are selected based on skin color and face detection is accomplished using a Support Vector Machine classifier. The locations of the eyes and mouth are detected inside the face region using neural network feature detectors. Pose estimation is performed based on a geometrical model, where the head is modeled as a spherical object that rotates upon the vertical axis. The triangle formed by the mouth and eyes defines a vertical plane that intersects the head sphere. By projecting the eyes-mouth triangle onto a two dimensional viewing plane, equations were obtained that describe the change in its angles as the yaw pose angle increases. These equations are then combined and used for efficient pose estimation. The system achieves real-time performance for live video input. Testing results assessing system performance are presented for both still images and video.
Negotiation-based task scheduling to minimize user’s electricity bills under dynamic energy prices (2014)

Dynamic energy pricing is a promising technique in the Smart Grid that incentivizes energy consumers to consume electricity more prudently in order to minimize their electric bills meanwhile satisfying their energy requirements. This has become a particularly interesting problem with the introduction of residential photovoltaic (PV) power generation facilities. This paper addresses the problem of task scheduling of (a collection of) energy consumers with PV power generation facilities, in order to minimize the electricity bill. A general type of dynamic pricing scenario is assumed where the energy price is both time-of-use and total power consumption-dependent. A negotiation-based iterative approach has been proposed that is inspired by the state-of-the-art Field-Programmable Gate Array (FPGA) routing algorithms. More specifically, the negotiation-based algorithm is used to rip-up and re-schedule all tasks in each iteration, and the concept of congestion is effectively introduced to dynamically adjust the schedule of each task based on the historical scheduling results as well as the (historical) total power consumption in each time slot. Experimental results demonstrate that the proposed algorithm achieves up to 51.8% improvement in electric bill reduction compared with baseline methods.
High-pressure Ca4Al6O13: An example of a calcium aluminate with three different types of coordination polyhedra for aluminum (2000)

The crystal structure of tetracalcium trialuminate (Ca4Al6O13), synthesized at 1250 °C and 2.5 GPa, has been determined from single-crystal X-ray data by direct methods [space group Pcan, Z = 8, a = 5.3002(2) Å, b = 17.7610(5), c = 21.0887(9) Å] and refined to R1 = 6.42%. The unit cell parameters of Ca4Al6O13 exhibit a relationship to those of perovskite: a ≈ √2 aPv, b ≈ 5 aPv. and c ≈ 4√2 aPv.. The diffraction data showed the typical features of a pseudotranslational symmetry: all reflections (hkl) with l equal 4n (n is an integer) had significantly higher intensity than the reflections with l ≠ 4n. Furthermore, diffuse streaks parallel to b* were observed. The new compound exhibits Al3+ in three different kinds of coordination polyhedra: octahedra, tetrahedra, and trigonal bipyramids. One of the two main building units is slightly corrugated sheets of perovskite-type corner sharing AlO6 octahedra perpendicular to [010]. The octahedral sheets are connected by layers containing tetrahedral zweier single chains. Within these layers the tetrahedral chains are linked by two different kinds of rods containing distorted trigonal bipyramids sharing common corners and edges, respectively. The tetrahedral chains and the bipyramidal rods are parallel to [100]. Charge compensation is achieved by the Ca ions, which are coordinated by 9 or 10 oxygen cations.
The effect of hydrodynamic insole on foot kinematics in individuals with flexible flatfoot: Case series using a single-subject design (2019)

The medial longitudinal arch of the foot is a dynamic structure while walking. The mobility of this structure in people with flexible flatfoot is partially or completely absent. The aim of this study was to investigate the efficacy of an insole that was designed to retrieve the medial longitudinal arch mobility in people with flatfoot. The study was a case series using a single-subject design. This single-subject design study was based on three subjects with flexible flatfoot. This study was designed in two phases: the baseline phase and the intervention phase. Each phase included five measurement sessions that were done in 5 consecutive weeks. We used the celeration-line method to detect the significant differences between the phases. Significant differences were recorded in the walking velocity, step length, and medial longitudinal arch mobility parameters when using the hydrodynamic insole. The results of this study showed that using the hydrodynamic insole may have a positive effect on the foot kinematics and gait parameters in people with flexible flatfoot.
Nutrition and cancer risk: an overview (2006)

The role of diet in cancer is a major public health issue Foods associated with a low risk of cancer are those typically included in the so-called Mediterranean diet, which is also associated with low mortality rates from cardiovascular disease. Implementing such a diet would involve increasing the consumption of fruits, vegetables, cereals, whole-grain foods and fish, while reducing the intake of refined carbohydrates and red meat. In addition, olive oil should replace saturated fats. Omega-3 fatty acids found in fish inhibit the growth in vitro of colon, breast and prostate cancers. Fibre can bind bile acids, which produce carcinogenic metabolites, and fermented fibre produces volatile fatty acids that can protect against colon cancer. It has been hypothesized that the anti-cancer actions of olive oil may relate to the ability of its mono-unsaturated fatty acid, oleic acid, to regulate oncogenes.
Probiotic and enterohemorrhagic Escherichia coli: An effective strategy against a deadly enemy? (2016)

Enterohemorrhagic Escherichia coli (EHEC) are major food-borne pathogens that constitute a serious public health threat. Currently, there is no specific treatment available for EHEC infections in human creating an urgent need for the development of alternative therapeutic strategies. Among them, one of the most promising approaches is the use of probiotic microorganisms. Even if many studies have shown the antagonistic effects of probiotic bacteria or yeast on EHEC survival, virulence, adhesion on intestinal epithelium or pathogen-induced inflammatory responses, mechanisms mediating their beneficial effects remain unclear. This review describes EHEC pathogenesis and novel therapeutic strategies, with a particular emphasis on probiotics. The interests and limits of a probiotic-based approach and the way it might be incorporated into global health strategies against EHEC infections will be discussed.
Similarity Search and Locality Sensitive Hashing using TCAMs (2010)

Similarity search methods are widely used as kernels in various machine learning applications. Nearest neighbor search (NNS) algorithms are often used to retrieve similar entries, given a query. While there exist efficient techniques for exact query lookup using hashing, similarity search using exact nearest neighbors is known to be a hard problem and in high dimensions, best known solutions offer little improvement over a linear scan. Fast solutions to the approximate NNS problem include Locality Sensitive Hashing (LSH) based techniques, which need storage polynomial in $n$ with exponent greater than $1$, and query time sublinear, but still polynomial in $n$, where $n$ is the size of the database. In this work we present a new technique of solving the approximate NNS problem in Euclidean space using a Ternary Content Addressable Memory (TCAM), which needs near linear space and has O(1) query time. In fact, this method also works around the best known lower bounds in the cell probe model for the query time using a data structure near linear in the size of the data base. TCAMs are high performance associative memories widely used in networking applications such as access control lists. A TCAM can query for a bit vector within a database of ternary vectors, where every bit position represents $0$, $1$ or $*$. The $*$ is a wild card representing either a $0$ or a $1$. We leverage TCAMs to design a variant of LSH, called Ternary Locality Sensitive Hashing (TLSH) wherein we hash database entries represented by vectors in the Euclidean space into $\{0,1,*\}$. By using the added functionality of a TLSH scheme with respect to the $*$ character, we solve an instance of the approximate nearest neighbor problem with 1 TCAM access and storage nearly linear in the size of the database. We believe that this work can open new avenues in very high speed data mining.
The utility of a monocyte monolayer assay in the assessment of intravenous immunoglobulin–associated hemolysis (2020)

MMA testing with autologous monocytes collected 5 to 10 days after receipt of high-dose IVIG can be used for the diagnosis of IVIG-associated hemolysis and may be of particular value in cases in which the Day 5 to 10 DAT is negative.
Regulation of Reactive Oxygen Species Homeostasis by Peroxiredoxins and c-Myc (2008)

Peroxiredoxins (Prxs) are highly conserved proteins found in most organisms, where they function primarily to scavenge reactive oxygen species (ROS). Loss of the most ubiquitous member of the family, Prx1, is associated with the accumulation of oxidatively damaged DNA and a tumor-prone phenotype. Prx1 interacts with the transcriptional regulatory domain of the c-Myc oncoprotein and suppresses its transforming activity. The DNA damage in tissues of prx1-/- mice is associated in some cases with only modest increases in total ROS levels. However, these cells show dramatic increases in nuclear ROS and reduced levels of cytoplasmic ROS, which explains their mutational susceptibility. In the current work, we have investigated whether changes in other ROS scavengers might account for the observed ROS redistribution pattern in prx1-/- cells. We show approximately 5-fold increases in Prx5 levels in prx1-/- embryo fibroblasts relative to prx1+/+ cells. Moreover, Prx5 levels normalize when Prx1 expression is restored. Prx5 levels also appear to be highly dependent on c-Myc, and chromatin immunoprecipitation experiments showed differential occupancy of c-Myc and Prx1 complexes at E-box elements in the prx5 gene proximal promoter. This study represents a heretofore unreported mechanism for the c-Myc-dependent regulation of one Prx family member by another and identifies a novel means by which cells reestablish ROS homeostasis when one of these family members is compromised.
A NEW HIGH TEMPERATURE AEROSOL DECOMPOSITION PROCESS FOR THE SYNTHESIS OF MIXED METAL OXIDES FOR CERAMICS AND CATALYSTS AND THEIR CHARACTERIZATION (1989)

Abstract A reactor system was developed which permitted the facile preparation of single and mixed metal oxides having high surface areas and unusual morphologies and physical properties. The synthetic technique produced compositions having a hollow sphere geometry, minimal pore structure, high purity, and low bulk density. Unusually high concentrations of solid solutions of modifying metal ions in host metal oxides were observed. KEYWORDS: High temperatureAerosolMetal oxidesCeramics.
Time-, Frequency-, and Space-varying K-Factor of Non-Stationary Vehicular Channels for Safety Relevant Scenarios. (2013)

Vehicular communication channels are characterized by a non-stationary time- and frequency-selective fading process due to fast changes in the environment. We characterize the distribution of the envelope of the first delay bin in vehicle-to-vehicle channels by means of its Rician $K$-factor. We analyze the time-frequency variability of this channel parameter using vehicular channel measurements at 5.6 GHz with a bandwidth of 240 MHz for safety-relevant scenarios in intelligent transportation systems (ITS). This data enables a frequency-variability analysis from an IEEE 802.11p system point of view, which uses 10 MHz channels. We show that the small-scale fading of the envelope of the first delay bin is Ricean distributed with a varying $K$-factor. The later delay bins are Rayleigh distributed. We demonstrate that the $K$-factor cannot be assumed to be constant in time and frequency. The causes of these variations are the frequency-varying antenna radiation patterns as well as the time-varying number of active scatterers, and the effects of vegetation. We also present a simple but accurate bi-modal Gaussian mixture model, that allows to capture the $K$-factor variability in time for safety-relevant ITS scenarios.
Glutathione Conjugates Recognize the Rossmann Fold of Glyceraldehyde-3-phosphate Dehydrogenase (1997)

Leukotriene (LT) C4 and other glutathione conjugates are synthesized intracellularly and then move to the plasma membrane for export. The intracellular proteins that bind these molecules and the significance of these interactions are poorly understood. To identify the binding sites of membrane-associated proteins that recognize these molecules, we utilized photoaffinity probes to label the inner leaflet of erythrocytes. The predominant molecule labeled with S-(p-nitrobenzyl)glutathione-[125I]4-azidosalicylic acid (PNBG-[125I]ASA) or LTC4-[125I]4-azidosalicylic acid (LTC4-[125I]ASA) was 38 kDa. The protein was labeled with PNBG-[125I]ASA, electroblotted to polyvinylidene difluoride membranes, digested in situ with lysyl endopeptidase, and two radiolabeled peptides isolated by reverse phase-high performance liquid chromatography. These contained an identity of 7/11 with amino acids 119-129, and 11/11 with amino acids 67-77 of human liver glyceraldehyde-3-phosphate dehydrogenase (GAPDH), respectively. Photoaffinity labeling with PNBG-[125I]ASA was blocked completely by 100 microM ATP and greater than 50% with 100 microM NAD+. LTC4-[125I]ASA binding to the NAD+ site was confirmed by V8 protease digestion of purified GAPDH labeled with LTC4-[125I]ASA or PNBG-[125I]ASA, with both labels localized to the 6.8-kDa N-terminal fragment. Photoaffinity labeling of HL-60 cells with LTC4-125I-ASA identified GAPDH as the predominant cytoplasmic binding protein in these cells. These data indicate that GAPDH is a membrane-associated and cytoplasmic protein which binds glutathione conjugates including LTC4.
Sensitive and Specific qPCR and Nested RT-PCR Assays for the Detection of Tobacco Streak Virus in Soybean (2021)

Tobacco streak virus (TSV) is a reemerging and understudied pathogen of soybean (Glycine max). Management of TSV is challenging due to the multiple modes of transmission, widespread susceptibility of commercial soybean, and lack of reliable diagnostic tests for the virus. Soybean plants with TSV-like, virus-like, or no symptoms were collected from commercial and research fields in seven counties in Wisconsin. Two sensitive assays were developed for the detection of TSV: a fluorescent dye-based quantitative reverse-transcription PCR (qPCR) assay and a nested reverse-transcription PCR (nRT-PCR). TSV was detected in 47 and 91% of symptomatic samples using the qPCR and nRT-PCR assays, respectively, suggesting that the nRT-PCR assay has higher sensitivity for detecting TSV. The qPCR assay’s limit of detection was determined at 10 fg and the assay was used to estimate the viral load in TSV-symptomatic samples. The titer of TSV in these samples was determined by absolute quantification and ranged from 15 fg to 0.796 ng. The two assays reported here provide diagnostic tools for the rapid and accurate detection of TSV that can aid in monitoring outbreaks, assessing management strategies, or screening soybean cultivars or accessions for resistance to the virus.

3-D image analysis of abdominal aortic aneurysm (2000)

In this paper we propose a technique for 3-D segmentation of abdominal aortic aneurysm (AAA) from computed tomography (CT) angiography images. Output data form the proposed method can be used for measurement of aortic shape and dimensions. Knowledge of aortic shape and size is very important for selection of appropriate stent graft device for treatment of AAA. The technique is based on a 3-D deformable model and utilizes the level-set algorithm for implementation of the method. The method performs 3-D segmentation of CT images and extracts a 3-D model of aortic wall. Once the 3-D model of aortic wall is available it is easy to perform all required measurements for appropriate stent graft selection. The method proposed in this paper uses the level-set algorithm instead of the classical active contour algorithm developed by Kass et al. The main advantage of the level set algorithm is that it enables easy segmentation surpassing most of the drawbacks of the classical approach. In the level-set approach for shape modeling, a 3-D surface is represented by a real 3-D function or equivalent 4-D surface. The 4-D surface is then evolved through an iterative process of solving the differential equation of surface motion. Surface motion is defined by velocity at each point. The velocity is a sum of constant velocity and curvature-dependent velocity. The stopping criterion is calculated based on image gradient. The algorithm has been implemented in MATLAB and C languages. Experiments have been performed using real patient CT angiography images and have shown good results.

Brain Deformation in Linear Head Impact (2009)

In this study, a 2D model of the head underwent linear impact and the experiments were simulated by finite element models. A cylinder with a diameter of 100mm and height of 20mm was filled with 5% gelatin, which was used as the brain surrogate material. The physical model was mounted onto a High Speed Computer Controlled Impact System to generate inertial loading of approximately 50 G average deceleration. The deformation of the samples was studied through image processing. Finite element (FE) analysis was used to simulate the experiments. The impact tests were modeled with two methods: a Lagrangian formulation with single point integration and an Arbitrary Lagrangian Eulerian (ALE) formulation with single point integration and void using LS-Dyna FE code. In the model with slip contact, the normal and shear strains reached more than 20% in some regions, which confirmed the risk of axonal injury in the linear impacts applied in this study. It was seen that in the Lagrangian models, in order to stabilize the simulation, high bulk moduli needed to be used; however, this resulted in much smaller void generation in the posterior region of the model. It was shown that the void generation reaches the experimental values by introducing 1–2 mm initial gaps between brain and skull. The ALE model was more stable and less sensitive to the bulk modulus, but showed smaller deformations.
Explosive Boiling of Water Films Adjacent to Heated Surfaces:  A Microscopic Description (2001)

Molecular dynamics simulations are used to investigate the separation of water films adjacent to a hot metal surface. The simulations clearly show that the water layers nearest the surface overheat and undergo explosive boiling. For thick films, the expansion of the vaporized molecules near the surface forces the outer water layers to move away from the surface. These results are of interest for mass spectrometry of biological molecules, steam cleaning of surfaces, and medical procedures.
Surface-Active Ionic Liquids in Catalytic Water Splitting (2018)

We report the application of surface-active ionic liquids as ligands and optional reaction media in iridium-catalyzed water oxidations. Three novel catalysts with N,N-dialkylimidazolidin-2-ylidene ligands based on amphiphilic imidazolium ionic liquids were synthesized and characterized. Excellent turn-over frequencies of up to 0.92 s-1 were obtained in catalytic water splitting, and activity was maintained for five consecutive catalytic cycles, with an overall turn-over number of 8967. The addition of external surface-active ionic liquid showed unexpected behaviour, because strongly enhanced initial reaction rates were observed.
