Drift-free tracking of rigid and articulated objects (2008)

Model-based 3D tracker estimate the position, rotation, and joint angles of a given model from video data of one or multiple cameras. They often rely on image features that are tracked over time but the accumulation of small errors results in a drift away from the target object. In this work, we address the drift problem for the challenging task of human motion capture and tracking in the presence of multiple moving objects where the error accumulation becomes even more problematic due to occlusions. To this end, we propose an analysis-by-synthesis framework for articulated models. It combines the complementary concepts of patch-based and region-based matching to track both structured and homogeneous body parts. The performance of our method is demonstrated for rigid bodies, body parts, and full human bodies where the sequences contain fast movements, self-occlusions, multiple moving objects, and clutter. We also provide a quantitative error analysis and comparison with other model-based approaches.
The Role of Pigment Epithelium-Derived Factor in the Pathophysiology and Treatment of Ovarian Hyperstimulation Syndrome in Mice (2013)

These observations provide a new perspective into the pathophysiology of OHSS, namely, high expression level of VEGF together with a nearly undetectable level of PEDF. A replacement therapy with rPEDF is suggested as an innovative physiological treatment for OHSS. Finally, control of the PEDF-VEGF reciprocal relationship could open new therapeutic avenues for other angiogenic-related fertility pathologies.
New Catalytic Approaches in the Stereoselective Friedel–Crafts Alkylation Reaction (2004)

After more than 125 years, the Friedel-Crafts alkylation is still one of the most studied and most utilized reactions in organic synthesis. What is the secret of this astonishing success? Perhaps the great versatility in scope and applicability continues to justify its crucial role in the synthesis of more and more complex molecules. However, it has taken more than a century for asymmetric catalytic versions of this reaction to be developed and subsequently extended to a range of aromatic compounds and alkylating agents. Herein we review recent developments in the design and use of catalytic and stereoselective strategies for the alkylation of aromatic systems and synthesis of a wide range of polyfunctionalized enantiomerically enriched compounds.
SPFD: A new method to express functional flexibility (2000)

In this paper, we propose a unique way to express functional flexibility by using sets of pairs of functions called "Sets of Pairs of Functions to be Distinguished" (SPFDs) rather than traditional incompletely specified functions. This method was very naturally derived from a unique concept for distinguishing two logic functions, which we explain in detail in this paper. The flexibility represented by an SPFD assumes that the internal logic of a node in a circuit can be freely changed, SPFDs make good use of this assumption, and they can express larger flexibility than incompletely specified functions in some cases. Although the main subject of this paper is to explain the concept of SPFDs, we also present an efficient method for calculating the functional flexibilities by SPFDs because the concept becomes useful only if there is an efficient calculation method for it. Moreover, we present a method to use SPFDs for circuit transformation along with a proof of the correctness of the method, We further make a comparison between SPFDs and compatible sets of permissible functions (CSPFs), which express functional flexibility by incompletely specified functions. As an application of SPFDs, we show a method to optimize LUT (look-up table) networks and experimental results.
Learning Feature Representations with a Cost-Relevant Sparse Autoencoder (2014)

There is an increasing interest in the machine learning community to automatically learn feature representations directly from the (unlabeled) data instead of using hand-designed features. The autoencoder is one method that can be used for this purpose. However, for data sets with a high degree of noise, a large amount of the representational capacity in the autoencoder is used to minimize the reconstruction error for these noisy inputs. This paper proposes a method that improves the feature learning process by focusing on the task relevant information in the data. This selective attention is achieved by weighting the reconstruction error and reducing the influence of noisy inputs during the learning process. The proposed model is trained on a number of publicly available image data sets and the test error rate is compared to a standard sparse autoencoder and other methods, such as the denoising autoencoder and contractive autoencoder.
Synthesis and Self-Assembly of Highly Monodispersed Quasispherical Gold Nanoparticles (2011)

We report the synthesis of cetyltrimethylammonium bromide (CTAB) assisted seed mediated growth of highly pure and monodispersed quasispherical gold nanoparticles (QAuNPs) and their self-assembly on the silica/glass substrates. The seed-mediated growth approach was modified to prepare size-tunable monodispersed QAuNPs with sizes ranging from 20 to 150 nm. The larger, more uniform seeds and lower CTAB concentration resulted in the formation of relatively large QAuNPs with improved monodispersity (relative standard deviation (RSD) of ∼5-8%) and high purity in their shapes. In addition, CATB-capped QAuNPs can be spontaneously assembled into closely packed and highly aligned superstructures with well-defined mutillayers (two to six layers) on silica substrates. Furthermore, CATB-capped QAuNPs can easily construct density-controllable QAuNP chips by electrostatic self-assembly, showing their promising applications for single-nanoparticle plasmonic sensors.

A simple all-digital PET system (2007)

Positron emission tomography~(PET) systems employ mixed-signal front-end to carry out relatively simple, and <i>ad hoc</i>, processing of the charge pulses generated upon event detection. To obtain, and maintain over time, proper calibrations of the mixed-signal circuitry for generating accurate event information is a challenging task due to the simplicity of the event processing, and the huge number of channels and multiplexing of the input signals found in modern PET systems. It is also difficult to modify or extend the event-processing technologies when needs arise because it would involve making changes to the circuitry. These limitations can be circumvented by applying digital signal-processing technologies for analyzing event pulses generated in PET. With digital technologies, optimized event-processing algorithms can be implemented and they can be modified or extended with ease when needed. The resulting PET data-acquisition (DAQ) system is easier to calibrate and maintain, can generate more accurate event information, and has better extendibility. In this paper, we present our work toward developing a scalable all-digital DAQ system for PET, built upon a personal-computer platform for reducing cost. We will present the overall architecture of this digital DAQ system, and describe our implementations of several components of the system.
Hyperlipidaemias and serum cytokines in patients with coronary artery disease (2003)

CAD patients are characterized by increased serum concentrations of TNFalpha. It seems likely that immune activation (TNFalpha, sTNFR 1, sTNFR 2, and IL- 10) in CAD patients is related to serum lipids levels.
Cytokinins and differentiation processes in Mercurialis annua : genetic regulation, relations with auxins, indoleacetic acid oxidases, and sexual expression patterns (1990)

Cytokinins in apices of eight isogenic lines of Mercurialis annua were compared (high performance liquid chromatography-gas chromatography mass spectroscopy-computer system). These apices develop normal staminate or pistillate differentiation processes (sex series lines) or empty (sterile), semiempty (semisterile), and full anthers (restored fertile male) in the sterility series in which a pistillate line was constructed. Both series developed two different cytokinin pathways: trans-cytokinins characterized the sex series, whereas the cis pathway characterized the sterility series. Drastic changes in the trans pathway (0/250 nanograms trans-zeatin and 166/0 nanograms zeatin nucleotide) induced staminate/pistillate differentiations. Less drastic quantitative changes in the cis pathway induced sterility or restored fertility compared to normal fertile anthers (192 or 669 nanograms/traces). The action of the complete cis-pathway was morphologically effective in the sterility series when the ratio of cis to trans pathways was 1:2 or 1:1 instead of 1:3. A final diagram shows the action of each sex or sterility allele on the enzymes controlling specific metabolites in both pathways. The discussion provides insights on the regulation of cytokinin-auxin balances specific for each kind of reproductive differentiation.
Controlling Thermal Stresses in Composites by Means of Fiber Prestress (1996)

A new method of applying a prestress to the fibers in composite laminates prior to and during cure is described, and several [0 P /90] T laminates produced at varying prestress levels are discussed. Experimental measurements described in this paper confirm that fiber prestressing can reduce or eliminate residual thermal stresses. This is evidenced by a reduction in the thermal warpage of unsymmetric [0 P /90] T laminates. An existing thermal analysis of unsymmetric laminates (developed by Hyer) is modified slightly in this paper to account for fiber prestressing, and is then used to predict out-of-plane deformations of the [0 P /90] T panels. Measurements compare well with theory. Specimens machined from the prestressed panels were also subjected to tensile loadings and inspected for matrix cracks in the 90° ply. It was found that fiber prestressing greatly reduced matrix cracking in [0 P /90] T specimens, but had little effect on [0/90 P ] T specimens.
Comparison and Analysis Study of SHA-3 Finalists (2012)

The competition of the NIST contenders in SHA-3 increased between the candidates hash functions to choose the winner in the end of 2012. However, NIST has outlined different requirements to measure different hash functions criteria such as, security, structure, and performance. Therefore, this paper addresses a comparative study of round 3 finalist SHA-3 candidates in, design of structure, complexity of security, with performance and cost, to measure the robustness of the algorithms through the Fundamentals Security Measurement Factors of Hash Function (FSMFHF) of Secure Hash Algorithm (SHA). For this reason, the result from this comprehensive comparison study between the finalist SHA-3 candidates such as, BLAKE, Grostl, JH, Keccak, and Skein, the Keccak, as well as JH are regarding the crucial competitors for the security future in the end of 2012, as a suitable designs for lightweight hash function. Whereas, Grostl hash function is tight in security, tight in structure of trade off (speed/memory) to implement in Virtex-7 2000T of FPGAs family hardware.
Phenylbutazone‐warfarin interaction in man: further stereochemical and metabolic considerations. (1983)

The pharmacokinetics and urinary metabolic profile of R and S-warfarin, following administration of a 1.5 mg/kg oral dose of racemic warfarin, alone and 4 days into an oral regimen of 100 mg phenylbutazone three times a day, was investigated in three volunteers using a stereospecific h.p.l.c. fluorescent assay. The mean elimination half-life of S-warfarin was increased from 25 to 46 h during phenylbutazone administration, whilst that of the R-isomer was decreased from 37 to 25 h. The peak unbound concentrations of both warfarin enantiomers were higher during phenylbutazone administration, due to displacement. Displacement was not stereoselective. The unbound clearance of more potent S-warfarin is decreased by four-fold during phenylbutazone administration, due to substantial inhibition of both 6- and 7-hydroxylation, significant pathways of elimination of S-warfarin in the absence of phenylbutazone. The unbound clearance of R-warfarin is almost unchanged during phenylbutazone administration, due to the marginal effect of phenylbutazone on 6- and 7-hydroxylation, themselves minor pathways of elimination of this enantiomer in the absence of phenylbutazone. The stereoselective reduction of S- and R-warfarin, to their respective SS and RS-alcohols, is also substantially inhibited during phenylbutazone administration. Collectively the data point to the complex effect of phenylbutazone administration on warfarin's pharmacokinetics.
Cellular origin and interactions involved in gamma-interferon production induced by OKt3 monoclonal antibody. (1982)

OKT3 monoclonal antibody, a human T cell mitogen, induced interferon production by cultured mononuclear cells at 10(-11) M concentrations. Interferon was secreted only under conditions wherein OKT3 was mitogenic, and production was correlated with cell proliferation. Thus, like mitogenesis, interferon secretion reached a peak 3 days after OKT3 stimulation, was inhibited by a factor(s) in human serum, and required 1000 times higher concentrations of Fab and F(ab')2 fragments of OKT3 for induction. The interferon was most likely of "gamma" (immune) type, because pH 2 and 56 degrees C treatments denatured it, whereas anti-alpha or -beta interferon antibodies did not. Mononuclear cells were fractionated into subpopulations that contained OKT4+ cells (helper/inducer T cells), OKT8+ cells (cytotoxic/suppressor T cells), and OKM1+ cells (monocytes) by combining sheep red blood cell rosetting and complement-mediated lysis using monoclonal antibodies against specific cell types. Both OKT4+ and OKT8+ cells proliferated upon OKT3 stimulation with the absolute requirement of OKM1+ cells. However, OKT4+ cells plus OKM1+ cells were necessary for the secretion of interferon. Studies with selective pretreatments with mitomycin C suggested that gamma-interferon was secreted by the OKT4+ cells and that the OKM1+ population subserved an accessory function.
Discovery and Validation of Barrett's Esophagus MicroRNA Transcriptome by Next Generation Sequencing (2013)

Using highly sensitive next-generation sequencing, we have performed a comprehensive genome wide analysis of microRNA in BE and GERD patients. Differentially expressed miRNA between BE and GERD have been further validated. Expression of miRNA between BE human tissues and BE cell lines are highly correlated. These miRNA should be studied in biological models to further understand BE development.
Glatiramer acetate (Copaxone) therapy induces CD8+ T cell responses in patients with multiple sclerosis (2002)

Glatiramer acetate (GA; Copaxone) is a random copolymer of glutamic acid, lysine, alanine, and tyrosine that is used therapeutically in patients with multiple sclerosis (MS). To investigate the mechanism of the drug's immunomodulatory effect, we used immunophenotypic approaches to characterize the precise nature of GA-induced T cell responses. We demonstrate here that healthy individuals and untreated MS patients exhibit prominent T cell proliferative responses to GA. However, these responses are different in distinct subsets of T cells. Whereas GA-induced CD4+ T cell responses are comparable in healthy individuals and MS patients, CD8+ T cell responses are significantly lower in untreated MS patients. Treatment with GA results in upregulation of these CD8+ responses with restoration to levels observed in healthy individuals. Both CD4+ and CD8+ GA-specific responses are HLA-restricted. GA therapy also induces a change in the cytokine profile of GA-specific CD4+ and CD8+ T cells. This study provides the first direct immunophenotypic evidence, to our knowledge, of GA-specific CD8+ T cell responses and their upregulation during the course of therapy, which may suggest a role for these responses in the immunomodulatory effects of the drug.
Spectrally Filtered Raman/Thomson Scattering Using a Rubidium Vapor Filter (2002)

A new spectrally e ltered light scattering apparatus is presented based on a diodelaser injected seeded titanium: sapphire laser and rubidium vapor e lter at 780.24 nm. It is shown that the realizable line center attenuation of quasi elastically scattered light, limited by a residual broad spectral linewidth, unseeded, component to the laser output, isashigh as 1 :67£10 5 using the laser system alone. Preliminary measurementsindicatethat incorporation of a set of dispersing prisms and a stimulated Brillouin scattering phase conjugate mirror external to the laser provides an additional approximate factor of 10 extinction. The utility of the system for measurement of electron density and temperature by Thomson scattering is demonstrated in a 3950-Pa (30-torr) argon dc discharge. At 100-mA current, an electron density of 3 :7£1013 cmi3 is measured on the discharge centerline with a 2 ae value of statistical uncertainty equal to 8 :0£10 11 cm i3 . The corresponding electron temperature is 0 :63§ 0:025 eV.
Regulation of perfusion and oxygenation by erythrocyte hemoglobin oxygen affinity (2008)

Responses to exchange transfusion using red blood cells (RBCs) with modified hemoglobin (Hb) oxygen (O 2 ) affinity were studied in the hamster window chamber model during acute anemia to determine its role on microvascular perfusion and tissue oxygenation. Allosteric effectors were introduced in the RBCs by electroporation. Inositol hexaphosphate (IHP) and 5‐hydroxymethyl‐2‐furfural (5HMF) were used to decrease and increase Hb‐O 2 affinity. In vitro P50s were modified to 10, 25, 45 and 50 mmHg, normal P50 is 32 mmHg. Allosteric effectors also decreased the Hill coefficient. Anemic condition was induced by isovolemic hemodilution exchanges using 6% dextran 70 kDa to 18% hematocrit (Hct). Modified RBCs (at 18% Hct in 5% albumin solution) were infused by exchange transfusion of 35% of blood volume. Systemic parameters, microvascular perfusion, capillary perfusion (functional capillary density, FCD) and microvascular pO 2 levels were measured. RBCs with P50 of 45 mmHg increased tissue pO 2 and decreased O 2 delivery (DO 2 ) and extraction (VO2) and RBCs with P50 of 60 mmHg reduced FCD, microvascular flow, tissue pO 2 , DO 2 and VO 2 . RBCs with increased Hb‐O 2 affinity maintained hemodynamic conditions, DO 2 and decreased tissue pO 2 . This study shows that in an anemic condition maximal tissue pO 2 does not correspond to maximal DO 2 and VO 2 . Supported by NIH BRP R24‐HL64395 and grants R01‐HL62354, R01‐HL62318 and R01‐HL76182.
SRv6Pipes: enabling in-network bytestream functions (2018)

IPv6 Segment Routing is a recent IPv6 extension that is generating a lot of interest among researchers and in industry. Thanks to IPv6 SR, network operators can better control the paths followed by packets inside their networks. This provides enhanced traffic engineering capabilities and is key to support Service Function Chaining (SFC). With SFC, an end-to-end service is the composition of a series of in-network services. Simple services such as NAT, accounting or stateless firewalls can be implemented on a per-packet basis. However, more interesting services like transparent proxies, transparent compression or encryption, transcoding, etc. require functions that operate on the bytestream.In this paper, we extend the IPv6 implementation of Segment Routing in the Linux kernel to enable network functions that operate on the bytestream and not on a per-packet basis. Our SRv6Pipes enable network architects to design end-to-end services as a series of in-network functions. We evaluate the performance of our implementation with different microbenchmarks.

Food Recommendation System Using Clustering Analysis for Diabetic Patients (2010)

Food and nutrition are a key to have good health. They are important for everyone to maintain a healthy diet especially for diabetic patients who have several limitations. Nutrition therapy is a major solution to prevent, manage and control diabetes by managing the nutrition based on the belief that food provides vital medicine and maintains a good health. Typically, diabetic patients need to avoid additional sugar and fat so the food pyramid is recommended to the patients for finding the substitution from the same food group. However, there is still a dietary diversity within food groups that can affect the diabetic patients. In this study, we proposed Food Recommendation System (FRS) by using food clustering analysis for diabetic patients. Our system will recommend the proper substituted foods in the context of nutrition and food characteristic. We used Self-Organizing Map (SOM) and K-mean clustering for food clustering analysis which is based on the similarity of eight significant nutrients for diabetic patient. At the end, the FRS was evaluated by nutritionists and it has performed very well and useful for nutrition area.
