Model-based face tracking for view-independent facial expression recognition (2003)

Facial expression recognition is necessary for designing any realistic human-machine interfaces. Previous published facial expression recognition systems achieve good recognition rates, but most of them perform well only when the user faces the camera and does not change his 3D head pose. We propose a new method for robust, view-independent recognition of facial expressions that does not make this assumption. The system uses a novel 3D model-based tracker to extract simultaneously and robustly the pose and shape of the face at every frame of a monocular video sequence. There are two main contributions. First, we demonstrate that the 3D information extracted through 3D tracking enables robust facial expression recognition in spite of large rotational and translational head movements (up to 90 degrees in head rotation). Second, we show that the Support Vector Machine is a suitable engine for robust classification. Recognition rates as high as 91 percent are achieved at classifying 5 distinct dynamic facial motions (neutral, opening/closing mouth, smile, raising eyebrow).
Multiscale Image Fusion Using the Undecimated Wavelet Transform With Spectral Factorization and Nonorthogonal Filter Banks (2012)

Multiscale transforms are among the most popular techniques in the field of pixel-level image fusion. However, the fusion performance of these methods often deteriorates for images derived from different sensor modalities. In this paper, we demonstrate that for such images, results can be improved using a novel undecimated wavelet transform (UWT)-based fusion scheme, which splits the image decomposition process into two successive filtering operations using spectral factorization of the analysis filters. The actual fusion takes place after convolution with the first filter pair. Its significantly smaller support size leads to the minimization of the unwanted spreading of coefficient values around overlapping image singularities. This usually complicates the feature selection process and may lead to the introduction of reconstruction errors in the fused image. Moreover, we will show that the nonsubsampled nature of the UWT allows the design of nonorthogonal filter banks, which are more robust to artifacts introduced during fusion, additionally improving the obtained results. The combination of these techniques leads to a fusion framework, which provides clear advantages over traditional multiscale fusion approaches, independent of the underlying fusion rule, and reduces unwanted side effects such as ringing artifacts in the fused reconstruction.

Mixed variable optimization for radio frequency ablation planning (2011)

We present a method towards optimization of multiple ablation probe placement to provide efficient coverage of a tumor for thermal therapy while respecting clinical needs such as limiting the sites of probe insertions at the pleura/liver surface, choosing secure probe trajectories and locations, avoiding ablation of critical structures, reducing ablation of healthy tissue and overlap of ablation zones. The ablation optimizer treats each ablation location independently, and the number of ablation probe placements itself is treated as a variable to be optimized. This allows us to potentially feedback the ablation after deployment and re-optimize the next steps during the plan. The optimization method uses a new class of derivate-free algorithms for solving a non-linear mixed variable problem with hard and soft constraints derived from clinical images. Our methods use discretization of the ablation volume, which can accommodate irregular shape of the ablation zone. The non-gradient based strategy produce new candidates to yield a feasible solution within a few iterations. In our simulation experiments this strategy typically reduced the ablation zone overlap and ablated healthy tissue ablated by 46% and 29%, respectively in a single iteration, resulting in a feasible solution to be found within 35 iterations. Our method for optimization provides efficient implementation for planning the coverage of a tumor while respecting clinical constraints. The ablation planning can be combined with navigation assistance to enable accurate translation and feedback of the plan.
THE MEASUREMENT OF RATE COEFFICIENTS IN SLURRY REACTORS (1981)

An analytical expression is derived from the equation of diffusion with a reversible reaction which allows the direct calculation of diffusion, mass transfer and kinetic coefficients from transient experiments in slurry reactors. A similar expression is obtained for the case when the slurry volume size is finite. These expressions are then used to calculate the diffusion coefficient and surface mass transfer coefficients of radioiodinated Bovine Serum Albumin desorbing from gel beads made of agarose and suspended in an aqueous slurry.

Critical Role of IL-5 in Antigen-Induced Pulmonary Eosinophilia, but Not in Lymphocyte Activation (2003)

Infiltration of antigen-specific CD4+ T cells and production of interleukin (IL)-5 in inflammatory regions play a central role in antigen-induced pulmonary eosinophilia. Genetically IL-5-deficient mice lack antigen-induced airway eosinophilia, but little is known about the role of IL-5 in accumulation and activation of CD4+ T cells in the lung and in airway hyperresponsiveness (AHR). ASCARIS SUUM extract (Asc) has been used to induce airway eosinophilia and analyze airway inflammation in IL-5 receptor alpha-chain-deficient (IL-5RKO) mice. We examined the role of IL-5 in CD4+ T cell activation, cytokine production, and AHR upon Asc sensitization. Pulmonary CD4+ T cells in Asc-immunized mice were activated and produced IL-5 upon local exposure to Asc in both wild-type (WT) and IL-5RKO mice. IL-2, IL-4, IL-5, IL-10 and eotaxin were detected in bronchoalveolar lavage fluid of both WT and IL-5RKO mice following exposure to Asc. Airway eosinophilia and AHR were seen only in WT mice, but not in IL-5RKO mice. We conclude that IL-5 appears to be required for the accumulation of eosinophils and AHR in the inflammatory lung. However, IL-5 does not play a critical role in the accumulation of activated CD4+ T cells in the inflammatory lung.

Centralized gene-based HIV-1 vaccine elicits broad cross-clade cellular immune responses in rhesus monkeys (2008)

One of the major challenges that must be met in developing an HIV-1 vaccine is devising a strategy to generate cellular immunity with sufficient breadth to deal with the extraordinary genetic diversity of the virus. Amino acids in the envelopes of viruses from the same clade can differ by more than 15%, and those from different clades can differ by more than 30%. It has been proposed that creating immunogens using centralized HIV-1 gene sequences might provide a practical solution to this problem. Such centralized genes can be generated employing a number of different strategies: consensus, ancestral, or center of tree sequences. These computer-generated sequences are a shorter genetic distance from any 2 contemporary virus sequences than those contemporary sequences are from each other. The present study was initiated to evaluate the breadth of cellular immunity generated through immunization of rhesus monkeys with vaccine constructs expressing either an HIV-1 global consensus envelope sequence (CON-S) or a single patient isolate clade B envelope sequence (clade B). We show that vaccine immunogens expressing the single centralized gene CON-S generated cellular immune responses with significantly increased breadth compared with immunogens expressing a wildtype virus gene. In fact, CON-S immunogens elicited cellular immune responses to 3-4-fold more discrete epitopes of the envelope proteins from clades A, C and G than did clade B immunogens. These findings suggest that immunization with centralized genes is a promising vaccine strategy for developing a global vaccine for HIV-1 as well as vaccines for other genetically diverse viruses.

Secure background watermarking based on video mosaicing (2004)

Digital watermarking was introduced during the last decade as a complementary technology to protect digital multimedia data. Watermarking digital video material has already been studied, but it is still usually regarded as watermarking a sequence of still images. However, it is well-known that such straightforward frame-by-frame approaches result in low performance in terms of security. In particular, basic intra-video collusion attacks can easily defeat basic embedding strategies. In this paper, an extension of the simple temporal frame averaging attack will be presented, which basically considers frame registration to enlarge the averaging temporal window size. With this attack in mind, video processing, especially video mosaicing, will be considered to produce a temporally coherent watermark. In other words, an embedding strategy will be proposed which ensures that all the projections of a given 3D point in a movie set carry the same watermark sample along a video scene. Finally, there will be a discussion regarding the impact of this novel embedding strategy on different relevant parameters in digital watermarking e.g. capacity, visibility, robustness and security.
B6 A Study for motion analysis in using sports tool (2008)

The requirement of the golf club performance is to hit the ball with distance and accuracy. In addition, the "feeling" for golf swing is a very important performance, but it is very difficult to evaluate the "feeling" quantitatively. In this paper, we investigated the index value which is related to the "feeling" on the golf swing's motion. The golf swing motion is measured by using the motion analysis system and the force plate. During the golf swing we analysised the three dimension center of gravity position and the force. The relationship between the analytical result and the "feeling" is investigated. As a result, we showed the close relationship between the quantity of these features to the "feeing" performance.
The Asymptotic Behaviour of Equidistant Permutation Arrays (1979)

An equidistant permutation array (EPA) A ( r λ v ) is a v × r array defined on a set V of r symbols such that every row is a permutation of V and any two distinct rows have precisely λ common column entries. Define R(r, λ) to be the largest value of v for which there exists an A ( r , λ; v ). Deza [ 2 ] has shown that where n = r – λ. Bolton [ 1 ] has shown that (*) In this paper, we show that equality holds in (*) for λ &gt; ┌ n /3┐( n 2 + n ). In order to do this we require several more definitions.
In Silico Screening for Novel Leucine Aminopeptidase Inhibitors with 3,4-Dihydroisoquinoline Scaffold (2020)

Cancers are the leading cause of deaths worldwide. In 2018, an estimated 18.1 million new cancer cases and 9.6 million cancer-related deaths occurred globally. Several previous studies have shown that the enzyme, leucine aminopeptidase is involved in pathological conditions such as cancer. On the basis of the knowledge that isoquinoline alkaloids have antiproliferative activity and inhibitory activity towards leucine aminopeptidase, the present study was conducted a study which involved database search, virtual screening, and design of new potential leucine aminopeptidase inhibitors with a scaffold based on 3,4-dihydroisoquinoline. These compounds were then filtered through Lipinski's "rule of five," and 25 081 of them were then subjected to molecular docking. Next, three-dimensional quantitative structure-activity relationship (3D-QSAR) study was performed for the selected group of compounds with the best binding score results. The developed model, calculated by leave-one-out method, showed acceptable predictive and descriptive capability as represented by standard statistical parameters r<sup>2</sup> (0.997) and q<sup>2</sup> (0.717). Further, 35 compounds were identified to have an excellent predictive reliability. Finally, nine selected compounds were evaluated for drug-likeness and different pharmacokinetics parameters such as absorption, distribution, metabolism, excretion, and toxicity. Our methodology suggested that compounds with 3,4-dihydroisoquinoline moiety were potentially active in inhibiting leucine aminopeptidase and could be used for further in-depth in vitro and in vivo studies.
Reducing 3D visual fatigue based on salient color model (2013)

In this study, a 3D image processing method of improving the visual sense of depth in line with the human visual perception characteristics was developed. Some of the visual processes that occur in human visual perception were reproduced to estimate the interest area that would correspond to the visual selective attention through the salient color model, the depth was translated on the basis of the interest area, and the image quality was enhanced in tune with the 3D image characteristics. In this way, the perceptive sense of depth can be improved and fatigue can be decreased when watching a 3D display.
Magnetically programmable surface acoustic wave radio frequency identification tags (2011)

A reconfigurable surface acoustic wave reflector using an integrated magnetoresistive bit was fabricated and evaluated for use in programmable radio frequency identification tags. It is shown that two distinct reflectivities can be achieved depending on the magnetic state of the bit. The experimental results are compared with theoretical calculations of optimal reflectivities achievable from resistively loaded surface acoustic wave transducers.
Construction of Corynebacterium glutamicum cells as containers encapsulating dsRNA overexpressed for agricultural pest control (2019)

Double-stranded RNA (dsRNA) inducing RNA interference (RNAi) is expected to be applicable to management of agricultural pests. In this study, we selected a ladybird beetle, Henosepilachna vigintioctopunctata, as a model target pest that devours vegetable leaves, and examined the effects of feeding the pest sterilized microbes highly accumulating a target dsRNA for RNAi induction. We constructed an efficient production system for diap1*-dsRNA, which suppresses expression of the essential gene diap1 (encoding death-associated inhibitor of apoptosis protein 1) in H. vigintioctopunctata, using an industrial strain of Corynebacterium glutamicum as the host microbe. The diap1*-dsRNA was overproduced in C. glutamicum by convergent transcription using a strong promoter derived from corynephage BFK20, and the amount of dsRNA accumulated in fermented cells reached about 75 mg per liter of culture. In addition, we developed a convenient method for stabilizing the dsRNA within the microbes by simply sterilizing the diap1*-dsRNA-expressing C. glutamicum cells with ethanol. When the sterilized microbes containing diap1*-dsRNA were fed to larvae of H. vigintioctopunctata, diap1 expression in the pest was suppressed, and the leaf-feeding activity of the larvae declined. These results suggest that this system is capable of producing stabilized dsRNA for RNAi at low cost, and it will open a way to practical application of dsRNA as an environmentally-friendly agricultural insecticide.
Volumetric Capture of Humans with a Single RGBD Camera via\n Semi-Parametric Learning (2019)

Volumetric (4D) performance capture is fundamental for AR/VR content\ngeneration. Whereas previous work in 4D performance capture has shown\nimpressive results in studio settings, the technology is still far from being\naccessible to a typical consumer who, at best, might own a single RGBD sensor.\nThus, in this work, we propose a method to synthesize free viewpoint renderings\nusing a single RGBD camera. The key insight is to leverage previously seen\n"calibration" images of a given user to extrapolate what should be rendered in\na novel viewpoint from the data available in the sensor. Given these past\nobservations from multiple viewpoints, and the current RGBD image from a fixed\nview, we propose an end-to-end framework that fuses both these data sources to\ngenerate novel renderings of the performer. We demonstrate that the method can\nproduce high fidelity images, and handle extreme changes in subject pose and\ncamera viewpoints. We also show that the system generalizes to performers not\nseen in the training data. We run exhaustive experiments demonstrating the\neffectiveness of the proposed semi-parametric model (i.e. calibration images\navailable to the neural network) compared to other state of the art machine\nlearned solutions. Further, we compare the method with more traditional\npipelines that employ multi-view capture. We show that our framework is able to\nachieve compelling results, with substantially less infrastructure than\npreviously required.\n

Molar Distributions of Equilibrium Systems (2018)

Abstract This paper deals with the observation that in most equilibrium systems of petroleum mixtures, the molar distribution shape of heavier fractions such as C7+ are very similar. This observation is verified for a wide range of equilibrium pressure-temperature conditions for a wide range of petroleum reservoir mixtures. The states of equilibrium studied include saturation pressure, two-phase flash within the phase envelope, and isothermal systems under the influence of gravitational segregation. The gamma distribution model is used to quantify molar distribution. The gamma distribution parameter a defines the distribution shape which provides a quantitative measure of similarity between equilibrium phases. The Hoffman, Crump and Hocott(1953) source of reservoir fluids for a saturated gas-oil system (containing only hydrocarbons) has been used in this study. The SRK EOS with zero binary interaction coefficients is used as the thermodynamic model to describe phase behavior of the Hoffman et al fluid system. A number of applications are given related to the similarity of equilibrium phase molar distributions.
SEMA 3C drives cancer growth by transactivating multiple receptor tyrosine kinases via Plexin B1 (2018)

Growth factor receptor tyrosine kinase (RTK) pathway activation is a key mechanism for mediating cancer growth, survival, and treatment resistance. Cognate ligands play crucial roles in autocrine or paracrine stimulation of these RTK pathways. Here, we show SEMA3C drives activation of multiple RTKs including EGFR, ErbB2, and MET in a cognate ligand-independent manner via Plexin B1. SEMA3C expression levels increase in castration-resistant prostate cancer (CRPC), where it functions to promote cancer cell growth and resistance to androgen receptor pathway inhibition. SEMA3C inhibition delays CRPC and enzalutamide-resistant progression. Plexin B1 sema domain-containing:Fc fusion proteins suppress RTK signaling and cell growth and inhibit CRPC progression of LNCaP xenografts post-castration <i>in vivo</i> SEMA3C inhibition represents a novel therapeutic strategy for treatment of advanced prostate cancer.
