Novel 3D model reconstruction method for the co-existence of diffuse and specular object surfaces (2007)

This project aims to develop a system that can reconstruct photorealistic 3D model of object automatically from a multi-view image sequence. The whole system consists of four major steps: camera calibration, volumetric modeling, surface model formation and texture mapping. A conservative volumetric object model is first reconstructed based on the shape-from-silhouette approach. Conventional volumetric modeling algorithms for refining the model assume that the object surface is Lambertian but many real objects exhibit both diffuse and specular reflections of illuminated light. We propose a novel volumetric modeling algorithm that can handle the co-existence of both diffuse and specular surfaces. Our algorithm also differs from others that the model is reconstructed by aggregating evidence in the voxel space via the use of voxel mask. We select some real objects for modeling and compare our volumetric modeling algorithm with the well-known Space Carving Algorithm. Reconstructed object models are presented, together with the model reprojection accuracy, to demonstrate the superior performance of the new 3D model reconstruction scheme.
Positive and negative oral contrast agents for combined abdominal and pelvic helical CT: first iodinated agent and second water. (2000)

Combined abdominal and pelvic helical computed tomography (CT) with intravenous contrast media was performed on 19 patients with 400 mL of diluted iodine solution 60 minutes before and 400 mL of water just before CT. The distal small bowel was opacified by the positive contrast agent, and the stomach by the negative contrast agent in all patients. The gastric contents were homogenous, and the density was a mean +/- standard deviation 2.5+/-7.3 HU. The difference between the densities of the gastric contents and of the gastric wall (mean +/- s.d. 80.8+/-20.9 HU) was statistically significant (p<.05). There were no pseudotumors. Thus our protocol, first diluted iodine solution and second water, can be used as a method for the oral administration of contrast agents for combined abdominal and pelvic helical CT with intravenous contrast media.
Expression of cyclin D1 in parathyroid carcinomas, adenomas, and hyperplasias: a paraffin immunohistochemical study. (1999)

In this study, we assessed the frequency of cyclin D1 protein expression in normal and neoplastic parathyroid tissue (10 parathyroid carcinomas, 28 adenomas, 18 hyperplasias, and 32 normal parathyroid glands) with use of a monoclonal anticyclin D1 antibody and a heat-induced epitope retrieval method. Overexpression of cyclin D1 was identified in 10 (91%) of 11 biopsy specimens from 10 patients with parathyroid carcinomas and in 11 (39%) of 28 parathyroid adenomas. In addition, 11 (61%) of 18 cases of parathyroid hyperplasia also expressed cyclin D1 protein, an observation not reported previously. These results confirm the high frequency of cyclin D1 expression in parathyroid carcinomas and adenomas. In addition, the results of this study indicate that overexpression of cyclin D1 protein is not limited to neoplastic proliferations of parathyroid tissue but is also seen in non-neoplastic proliferations of parathyroid gland. Cyclin D1 protein expression was rarely (<6%) present in normal parathyroid tissue.
Evaluation of extracts and oils of tick‐repellent plants from Sweden (2005)

Abstract. Leaves of Myrica gale Linnaeus (Myricaceae), Rhododendron tomentosum (Stokes) H. Harmaja (formerly Ledum palustre Linnaeus: Ericaceae) and Artemisia absinthium Linnaeus (Asteraceae) were extracted with organic solvents of different polarities and the essential oils of leaves were obtained by steam distillation. The extracts or oils were tested in the laboratory for repellency against host-seeking nymphs of Ixodes ricinus Linnaeus (Acari: Ixodidae). Rhododendron tomentosum oil, 10%, diluted in acetone, exhibited 95% repellency; R. tomentosum and A. absinthium extracts in ethyl acetate, > 70% repellency; A. absinthium extract in hexane, approximately 62% repellency; and M. gale oil, 10%, approximately 50% repellency on I. ricinus nymphs. Compounds in the leaf extracts or in the oils were collected by solid phase microextraction (SPME) and identified by gas chromatography-mass spectrometry (GC-MS) and/or MS. Characteristic volatiles detected from oil or extract of M. gale were the monoterpenes 1,8-cineole, alpha-terpineol, 4-terpineol and thujenol; and of R. tomentosum myrcene and palustrol. Characteristic volatiles from leaf extracts of A. absinthium were sabinene, oxygenated monoterpenes, e.g. thujenol and linalool, and geranyl acetate. Each plant species synthesized numerous volatiles known to exhibit acaricidal, insecticidal, 'pesticidal' and/or arthropod repellent properties. These plants may be useful sources of chemicals for the control of arthropods of medical, veterinary or agricultural importance.
The population dynamics of maternal-effect selfish genes. (1994)

We use population genetic methods to describe the expected population dynamics of the selfish-gene chromosomal factor, Medea (maternal-effect dominant embryonic arrest), recently discovered in flour beetles, genus Tribolium. In the absence of deleterious effects on gross fecundity, Medea factors spread to fixation for all degrees of maternal-effect lethality greater than zero and the rate of spread is proportional to the strength of the maternal-effect. The rate of spread when rare is very slow, on the order of the frequency squared p2, but this can be accelerated to order p when there is density regulation at the level of families as is known to occur for some genetic strains of flour beetles. When there are general deleterious effects of Medea on fecundity, affecting all offspring genotypes in addition to the genotype-specific maternal effect, then a stable interior polymorphism is possible. The location of the interior equilibrium and the probability of loss or fixation are sensitive to the degree of dominance of these fecundity effects.
A monoclonal antibody reacting with a determinant on leptospiral lipopolysaccharide protects guinea pigs against leptospirosis (1986)

An IgA monoclonal antibody (MUM/F1-1/copenhageni) was produced from a mouse immunised with Leptospira interrogans serovar copenhageni. The antibody showed partial serogroup specificity by agglutination and by reaction in enzyme immunoassay, and opsonised homologous leptospires for phagocytosis by cultured mouse macrophages. Immunodiffusion and Western-blotting experiments indicated that MUM/F1-1/copenhageni reacted with a carbohydrate determinant in the leptospiral lipopolysaccharide. Daily administration of purified MUM/F1-1/copenhageni IgA before and after challenge with 2 X 10(8) virulent homologous leptospires passively protected newborn guinea pigs against lethal leptospirosis.
Effect of time-varied magnetic field on inflammatory response in macrophage cell line RAW 264.7 (2012)

The aim of this feasibility study was to determine the effectiveness of a commercially manufactured magnetic field (MF) device as an adjunct to pharmaceuticals during acute phase inflammatory response. The goal was to determine if inflammatory response interleukins IL-1, IL-6, IL-10, and tumor necrosis factor-alpha (TNF-α) would be affected by a 30 Hz time-varying magnetic field (MF). RAW 264.7 macrophage-like cells were induced with Gram-negative bacteria lipopolysaccharide (LPS) to initiate an acute inflammatory reaction. Following lipopolysaccharide (LPS) treatment, both inflamed and control cells were exposed to MF for 1 h. After MF exposure, cytokines of interest were measured and compared with controls. Outcomes revealed that LPS challenged cells continuously exposed to a 30 Hz time-varying magnetic field for 1 h demonstrated significant changes compared with controls. From cytokine test it was determined that MF exposure significantly decreased levels of IL-6 and IL-10 compared to unexposed counterparts. TNF-α production was significantly affected when MF was applied to cells only, but not to inflamed cells. Results suggest that the biological effect of 1 h exposure to a 30 Hz time-varied magnetic field may act to down regulate specific cytokines in an inflamed environment.

Gene Cloning, Overproduction, and Characterization of Thermolabile Alkaline Phosphatase from a Psychrotrophic Bacterium (2005)

The gene encoding alkaline phosphatase from the psychrotrophic bacterium Shewanella sp. SIB1 was cloned, sequenced, and overexpressed in Escherichia coli. The recombinant protein was purified and its enzymatic properties were compared with those of E. coli alkaline phosphatase (APase), which shows an amino acid sequence identity of 37%. The optimum temperature of SIB1 APase was 50 degrees C, lower than that of E. coli APase by 30 degrees C. The specific activity of SIB1 APase at 50 degrees C was 3.1 fold higher than that of E. coli APase at 80 degrees C. SIB1 APase lost activity with a half-life of 3.9 min at 70 degrees C, whereas E. coli APase lost activity with a half-life of >6 h even at 80 degrees C. Thus SIB1 APase is well adapted to low temperatures. Comparison of the amino acid sequences of SIB1 and E. coli APases suggests that decreases in electrostatic interactions and number of disulfide bonds are responsible for the cold-adaptation of SIB1 APase.
Compiling the language Balsa to delay insensitive hardware (1997)

A silicon compiler, Balsa-c, has been developed for the automatic synthesis of asynchronous, delay-insensitive circuits from the language Balsa. Balsa is derived from CSP with similar language constructs and a single-bit granularity type system. Balsa compiles to intermediate handshake circuits by an extended form of the compilation function used in the Tangram system. The handshake circuits are subsequently mapped to CMOS implementations of 4-phase bundled-data asynchronous circuits by a suite of parameterised component-generating scripts within the Cadence design framework.
Structure of Tantalum Nitrides (1971)

The crystal structure of tantalum nitrides is examined by X-ray and electron diffraction techniques and the following seven phases are identified: TaN ∼0.05 (cubic, β-phase), Ta 2 N (hexagonal, γ-phase), δ-TaN (hexagonal), ε -TaN (hexagonal), Ta 5 N 6 (hexagonal), Ta 4 N 5 (tetragonal) and Ta 3 N 5 (tetragonal or monoclinic). Thin films of Ta nitrides for electron diffraction study were prepared by nitriding thin evaporated films of tantalum in ammonia and nitrogen. By heating thin films of Ta 3 N 5 in vacuum, the phase transformations occur successively as follows: Ta 3 N 5 →Ta 4 N 5 →Ta 5 N 6 → ε -TaN→Ta 2 N. The stucture of each nitride form is discussed.
Impaction of the Fore-Stomachs and Abomasum in a Cow (1953)

On Jan. 2, 1953, a six-year-old Brown Swiss cow was admitted to Stange Memorial Clinic with a history of having been bloated for three days. A trocar and cannula had been inserted in the left paralumbar fossa in the field and the cannula was still in place when the patient entered the clinic.
Network Coding Made Practical (2006)

We propose a new architecture for wireless mesh networks. In addition to forwarding packets, routers mix (i.e., code) packets from different sources to increase the information content of each transmission. We show that intelligently mixing packets increases network throughput. Our design is rooted in the theory of network coding. In contrast to prior work on network coding, which is mainly theoretical and focuses on multicast traffic, ours is practical and solves the common case of unicast traffic. We present the first implementation of network coding in a wireless network. Our system introduces a coding layer between the IP and MAC layers. It works with UDP and TCP traffic, and hence seamlessly integrates with existing applications. We evaluate our design on a 34-node wireless testbed and show that it delivers a 3-4x increase in the throughput ofwireless mesh networks.
Tissue-type Plasminogen Activator Acts as a Cytokine That Triggers Intracellular Signal Transduction and Induces Matrix Metalloproteinase-9 Gene Expression (2005)

Tissue-type plasminogen activator (tPA), a serine protease well known for generating plasmin, has been demonstrated to induce matrix metalloproteinase-9 (MMP-9) gene expression and protein secretion in renal interstitial fibroblasts. However, exactly how tPA transduces its signal into the nucleus to control gene expression is unknown. This study investigated the mechanism by which tPA induces MMP-9 gene expression. Both wild-type and non-enzymatic mutant tPA were found to induce MMP-9 expression in rat kidney interstitial fibroblasts (NRK-49F), indicating that the actions of tPA are independent of its proteolytic activity. tPA bound to the low density lipoprotein receptor-related protein-1 (LRP-1) in NRK-49F cells, and this binding was competitively abrogated by the LRP-1 antagonist, the receptor-associated protein. In mouse embryonic fibroblasts (PEA-13) lacking LRP-1, tPA failed to induce MMP-9 expression. Furthermore, tPA induced rapid tyrosine phosphorylation on the beta subunit of LRP-1, which was followed by the activation of Mek1 and its downstream Erk-1 and -2. Blockade of Erk-1/2 activation by the Mek1 inhibitor abolished MMP-9 induction by tPA in NRK-49F cells. Conversely, overexpression of constitutively activated Mek1 induced Erk-1/2 phosphorylation and MMP-9 expression. In mouse obstructed kidney, tPA, LRP-1, and MMP-9 were concomitantly induced in the renal interstitium. Collectively, these results suggest that besides its classical proteolytic activity, tPA acts as a cytokine that binds to the cell membrane receptor LRP-1, induces its tyrosine phosphorylation, and triggers intracellular signal transduction, thereby inducing specific gene expression in renal interstitial fibroblasts.
CD28 costimulation regulates FOXP3 in a RelA/NF‐κB‐dependent mechanism (2010)

The molecular mechanisms whereby CD28 alone or associated with TCR can regulate FOXP3 expression are not understood, although the importance of CD28 as a pivotal regulator of CD4(+) CD25(+) FOXP3(+) T cells is well recognized. We previously demonstrated that unique CD28-induced, NF-κB-dependent signals were sufficient to activate FOXP3 transcription in human CD4(+) CD25(-) T cells; however, the exact mechanisms are currently unknown. In this study, we have identified novel κB-binding sites on FOXP3 gene and demonstrated that CD28 signals mediated FOXP3 trans activation by nuclear translocation of RelA/NF-κB and not of c-Rel. The occupancy of FOXP3 κB-binding sites by RelA dimers that correlated with histone acetylation and recruitment of Pol II were required both to initiate FOXP3 transcription and to control the promoter occupancy by NFAT. Interestingly, knockdown of RelA in CD4(+) CD25(-) T cells stimulated through TCR and CD28 significantly affected FOXP3 expression, confirming that also the transcriptional activation of FOXP3 gene by TCR in the presence of CD28-costimulatory signals is RelA-dependent. In conclusion, these data suggest a new mechanism by which FOXP3 is activated and supports the critical role of CD28 in the regulation of peripheral tolerance.
Activity of lysosomal cysteine proteinase during differentiation of rat skeletal muscle (1983)

Cysteine-proteinase activities were measured in extracts of pre- and post-fusion populations of rat myogenic line L6 cells and in extracts of whole rat muscle. Activities of cathepsins B, L and H were compared. The substrates used included Z-Phe-Arg-NMec (cathepsins B and L), Z-Arg-Arg-NMec (cathepsin B), and Arg-NMec (cathepsin H) (where Z = benzyloxycarbonyl, and NMec = 4-methyl-7-coumarylamide); the enzyme activities were more specifically differentiated by appropriate concentrations of the inhibitors Z-Phe-Phe-CHN2 (CHN2 = diazomethane), bestatin and E-64 [L-trans-epoxysuccinyl-leucylamido(4-guanidino)butane]. These experiments have demonstrated the feasibility of determining the cysteine-proteinase activities of myoblasts from a single (60 mm-diameter) Petri dish, with enzyme concentrations in the range of 5-20 ng/ml. Specific activities of the enzymes in L6 cells increased 2-20-fold after fusion. Concentrations of cysteine proteinases in extracts from cultured myoblasts were two orders of magnitude greater than those in muscle-tissue extracts. Cultured-cell extracts contained endogenous inhibitor(s) to purified rat cathepsins B, L and H.
Nonspecific immunomodulation influences resistance of mice to experimental infection with <i>Mesocestoides</i> corti and <i>Ascaris suum</i> (1991)

The influence of nonspecific immunomodulation on the course of experimental infection was examined in larval cestodosis (Mesocestoides corti) and ascaridosis (Ascaris suum) in mice. Immunosuppressive treatment (with azathioprine or hydrocortisone) resulted in a decrease of resistance in both models. The subsequent administration of T-activin to immunosuppressed mice led to the restoration of resistance to a level equal to that of untreated control mice. The administration of different immunomodulators partially protected mice against M. corti (T-activin, thymomodulin) or A. suum (T-activin, thymomodulin, thymosin fr.5, bursa-activin) infection. The protective effect of different treatments did not correlate with the level of specific antibody in the sera of infected mice. These results, which confirmed the decisive role of T-cell immunity in the resistance to the helminth infections, raise the possibility of the use of immunomodulators (thymic preparations) in the immunoprophylaxis of helminthoses.
Learning Support Vector Machines for A Multi-View Face Model (1999)

Support Vector Machines have shown great potential for learning classification functions that can be applied to object recognition. In this work, we extend SVMs to model the appearance of human faces which undergo nonlinear change across multiple views. The approach uses inherent factors in the nature of the input images and the SVM classification algorithm to perform both multi-view face detection and pose estimation.

Engineering of a Mouse for the in Vivo Profiling of Estrogen Receptor Activity (2001)

In addition to their well known control of reproductive functions, estrogens modulate important physiological processes. The identification of compounds with tissue-selective activity will lead to new drugs mimicking the beneficial effects of estrogen on the prevention of osteoporosis and cardiovascular or neurodegenerative diseases, while avoiding its detrimental proliferative effects. As an innovative model for the in vivo identification of new selective estrogen receptor modulators (SERMs), we engineered a mouse genome to express a luciferase reporter gene ubiquitously. The constructs for transgenesis consist of the reporter gene driven by a dimerized estrogen-responsive element (ERE) and a minimal promoter. Insulator sequences, either matrix attachment region (MAR) or beta-globin hypersensitive site 4 (HS4), flank the construct to achieve a generalized, hormoneresponsive luciferase expression. In the mouse we generated, the reporter expression is detectable in all 26 tissues examined, but is induced by 17beta-estradiol (E2) only in 15 of them, all expressing estrogen receptors (ERs). Immunohistochemical studies show that in the mouse uterus, luciferase and ERs colocalize. In primary cultures of bone marrow cells explanted from the transgenic mice and in vivo, luciferase activity accumulates with increasing E(2) concentration. E2 activity is blocked by the ER full antagonist ICI 182,780. Tamoxifen shows partial agonist activity in liver and bone when administered to the animals. In the mouse system here illustrated, by biochemical, immunohistochemical, and pharmacological criteria, luciferase content reflects ER transcriptional activity and thus represents a novel system for the study of ER dynamics during physiological fluctuations of estrogen and for the identification of SERMs or endocrine disruptors.
A Novel Whiskerless Schottky Diode for Millimeter and Submillimeter Wave Application (1987)

A novel whiskerless Schottky diode has been developed in which shunt capacitance is minimized by means of an etched surface channel. This structure is easily fabricated and the DC I-V characteristics areas good as those of the best available whisker-contacted devices. Preliminary RF characterization in an unoptimized mount at 110 GHz has yielded room temperature SSB mixer noise temperature of 950 K and SSB conversion loss of 6.4 dB. The diode is robust and can be operated at cryogenic temperatures. Potential applications include waveguide and planar mixers, planar arrays, multipliers, varactor tuners, and microwave integrated circuits.
One-Pot Synthesis of Ag@TiO<sub>2</sub> Core−Shell Nanoparticles and Their Layer-by-Layer Assembly (2000)

Silver nanoparticles coated with a uniform, thin shell of titanium dioxide are synthesized via a remarkably simple one-pot route, where the reduction of Ag+ to Ag0 and the controlled polymerization of TiO2 on the surface of silver crystallites take place simultaneously. The prepared dispersions of coated nanoparticles display a surface plasmon band, which is significantly red-shifted with respect to that of bare Ag. High-quality ultrathin films of the core−shell clusters are prepared via layer-by-layer assembly. The nanoparticles are arranged in closely packed layers interlaced with polyelectrolyte producing a stratified core−shell hybrid material with unique structure and catalytic and electron-transport properties.
Adaptive Quantization of Neural Networks (2018)

Despite the state-of-the-art accuracy of Deep Neural Networks (DNN) in various classification problems, their deployment onto resource constrained edge computing devices remains challenging, due to their large size and complexity. Several recent studies have reported remarkable results in reducing this complexity through quantization of DNN models. However, these studies usually do not consider the change in loss when performing quantization, nor do they take the disparate importance of DNN connections to the accuracy into account. We address these issues in this paper by proposing a new method, called adaptive quantization, which simplifies a trained DNN model by finding a unique, optimal precision for each connection weight such that the increase in loss is minimized. The optimization problem at the core of this method iteratively uses the loss function gradient to determine an error margin for each weight and assign it a precision accordingly. Since this problem uses linear functions, it is computationally cheap and, as we will show, has a closed-form approximate solution. Experiments on MNIST, CIFAR, and SVHN datasets showed that the proposed method can achieve near or better than state-of-the-art reduction in model size with similar error rate. Furthermore, it can achieve compressions close to floating-point model compression methods without loss of accuracy.
