Feature detection algorithm based on a visual system model (2002)

An algorithm for the detection of visually relevant luminance features is presented. The algorithm is motivated and directed by current models of the visual system. The algorithm detects edges (sharp luminance transitions) and narrow bars (luminance cusps) and marks them with the proper polarity. The image is first bandpass filtered with oriented filters at a number of scales an octave apart. The suprathreshold image contrast details at each scale are then identified and are compared across scales to find locations in which the signal polarity (sign) is identical at all scales, representing a minimal level of phase congruence across scales. These locations maintain the polarity of the bandpass-filtered image. The result is a polarity-preserving features map representing the edges with pairs of light and dark lines or curves on corresponding sides of the contour. Similarly, bar features are detected and represented with single curves of the proper polarity. The algorithm is implemented without free (fitted) parameters. All parameters are directly derived from visual models and from measurements on human observers. The algorithm is shown to be robust with respect to variations in filter parameters and requires no use of quadrature filters or Hilbert transforms. The possible utility of such an algorithm within the visual system and in computer vision applications is discussed.
Controlled Doping of MS<sub>2</sub> (M=W, Mo) Nanotubes and Fullerene‐like Nanoparticles (2011)

Lubricating nanoparticles: The effect of doping semiconductor hollow closed-fullerene-like nanoparticles of MoS2 and WS2 has been overlooked to date. Rhenium doping of these nanoparticles leads to a marked increase in the nanoparticle's conductivity, reduced agglomeration, and a great reduction in friction and wear (see picture) that approaches superlubricity.
Overview of Bacterial Cellulose Production and Application (2014)

Bacterial cellulose (BC), produced by aerobic bacteria received ample of attention due to its unique physiochemical properties compared to plant cellulose. Intense researches on BC mainly focus on biosynthetic process to achieve low-cost preparation and high cellulose production. BC has been used as biomaterial for medical field, electrical instrument and food ingredient. However, BC alone has limited capabilities to fulfil current demand on high-performance biomaterials. Hence, BC composite has been introduced to enhance BC properties through addition of reinforcement materials. This review discusses current knowledge in fermentation process and potential application of BC including its application in food industry.
Public key infrastructure for mobile banking security (2009)

The advantage of mobile penetration enables mobile operators to provide value added service such as mobile banking, GPRS based interactive application and enhanced security in the internet bsanking etc. This however, requires robust End-to-End security solutions. Mobile banking is attractive because it is a convenient approach to perform banking from any where any time, but there are security concerns in the implementation which include problems with GSM network, SMS, GPRS protocols and security problems. In this paper an end-to-end security framework using PKI for mobile banking is proposed. Performance of the proposed model is presented in this paper.
The Lemur’s Tale - Story-Telling in Primates and Other Socially Intelligent Agents (1999)

The European Active Surveillance Study on Intrauterine Devices is the first large-scale, prospective, non-interventional study to compare the perforation risk in LNG-IUS and copper IUD users. It is the first to examine the independent roles that breastfeeding status and postpartum status have on perforation risk. Conducted during routine clinical practice, the findings are generalizable to broader populations.

BBI and/or BBIC could be a useful agent for treatment of prostate diseases.
Characterization of HGF/Met Signaling in Cell Lines Derived From Urothelial Carcinoma of the Bladder (2014)

There is mounting evidence of oncogenic hepatocyte growth factor (HGF)/Met signaling in urothelial carcinoma (UC) of the bladder. The effects of three kinase inhibitors, cabozantinib, crizotinib and EMD1214063, on HGF-driven signaling and cell growth, invasion and tumorigenicity were analyzed in cultured UC cell lines. SW780 xenograft growth in SCID and human HGF knock-in SCID (hHGF/SCID) mice treated with cabozantinib or vehicle, as well as tumor levels of Met and pMet, were also determined. Met content was robust in most UC-derived cell lines. Basal pMet content and effector activation state in quiescent cells were low, but significantly enhanced by added HGF, as were cell invasion, proliferation and anchorage independent growth. These HGF-driven effects were reversed by Met inhibitor treatment. Tumor xenograft growth was significantly higher in hHGF/SCID mice vs. SCID mice and significantly inhibited by cabozantinib, as was tumor phospho-Met content. These studies indicate the prevalence and functionality of the HGF/Met signaling pathway in UC cells, suggest that paracrine HGF may contribute to UC tumor growth and progression, and that support further preclinical investigation of Met inhibitors for the treatment of UC is warranted.
Aromatic substitution of olefins. The reaction of ferrocene with styrene in the presence of palladium(II) acetate (1970)

Ferrocene reacts with styrene to produce trans-α-styrylferrocene in the presence of palladium(II) acetate, which exemplifies an extremely convenient method for the direct synthesis of alkenylferrocenes.
Evaluation of 4,4′‐diisothiocyanatostilbene‐2,2′‐disulfonic acid in the inhibition of rouleaux formation (1996)

DIDS effectively resolved the serologic problems associated with the presence of rouleaux, without affecting the results of the test system itself. Implementation of this method to inhibit the rouleaux-forming properties of serum and plasma specimens can be useful in serologic testing.
Embedded Test and Debug of Full Custom and Synthesizable Microprocessor Cores (2000)

This paper compares and contrasts two very different approaches to testing cached CPU macro-cells that are typically embedded in a System on Chip (SoC). One uses a test bus to apply functional vectors, while the other uses a combination of scan insertion, memory BIST and test collars. IP protection issues and non-intrusive tracing are also discussed.
Prototype design and test results of a high temperature remote actuator controller (2002)

This report presents an early "Proof-of-Concept" prototype for a distributed aircraft actuator controller operable at 155/spl deg/C. The prototype employs a minimum number of parts and offers features such as ratiometric position sensing and a pulse width modulated valve drive. Test results are also presented and discussed.
Purification and Characterization of a Lipase from Candida curvata Lodder and Kreger — van Rij CBS 570 (1985)

Abstract The purification of the lipase from Candida curvata CBS 570 was achieved steps. Its optimum pH is 6 and its optimum temperature range is Iff C to 60°C. This enzyme is thermoresistant and only loses 20% of its activity when heated at 50°C during 30 minutes. Its activation energy is 144 kcal/mole and its inactivation energy 22 kcal/mole. Its molecular weight was determined to be 195000. EDTA, p‐chloromercuri benzoate, N‐ethyl‐ and iodoacetamide have no influence on the activity of this enzyme, whereas Cu ++ and Zn ++ show strong inhibitory effects. The lipase activity is induced by the presence of triglycerides and inhibited by the presence of glucose. This enzyme strongly attacks triolein and trilinolein molecules, however it only hydrolyzes a little tristearin and trilinolenin.
Effects of enzyme supplementation on performance, nutrient digestibility, gastrointestinal morphology, and volatile fatty acid profiles in the hindgut of broilers fed wheat-based diets (2005)

A growth trial and a metabolism trial were conducted as 2 experiments to investigate the effects of dietary enzyme supplementation (primarily xylanase and beta-glucanase) on performance, nutrient digestibility, intestinal morphology, digestive organ size, and volatile fatty acid profiles in the hindgut of broiler chickens fed wheat-based diets. The experimental diets in both trials consisted of a wheat-based control diet supplemented with 0, 200, 400, 600, 800, or 1,000 mg/kg enzyme. Diets were given to the birds from d 7 to 42 of age. In the growth trial, enzyme supplementation improved performance of the broilers; daily gain and feed conversion increased linearly (P < 0.01) with increasing levels of enzyme supplementation. Enzyme inclusion decreased the size of the digestive organs and the gastrointestinal tract to some extent. The relative length of each intestinal segment decreased linearly (P < 0.05). The relative weight of the anterior intestine on d 21 and ileum on d 42 also decreased linearly (P < 0.01). On d 21 and 42, there were negative linear (P < 0.05) relationships between increasing enzyme supplementation and the relative weight of the liver and pancreas, respectively. Furthermore, there was a linear (P < 0.01) increase in total volatile fatty acid content in ileum on d 21 and in the cecum on d 21 and 42. During each period of the metabolism trial, apparent crude protein digestibility increased linearly (P < 0.05), whereas no differences were detected (P > 0.05) in AME.

Stem Cell Factor Regulates the Melanocyte Cytoskeleton (1996)

Stem cell factor is a growth factor for normal human melanocytes, that acts through the tyrosine kinase receptor c-kit. We have previously demonstrated that stem cell factor increases melanocyte adhesion and migration on fibronectin, and regulates integrin protein expression. In this report, we have characterized the effect of stem cell factor on the organization of the actin cytoskeleton in human melanocytes attached to fibronectin, and have examined the effect of stem cell factor on the phosphorylation of the focal contact protein paxillin and on the expression of the focal contact proteins talin, paxillin, vinculin, and alpha-actinin. Paxillin is a vinculin-binding protein that is a substrate of focal adhesion kinase, a nonreceptor tyrosine kinase, and in its phosphorylated form is believed to stabilize focal contacts. We show that stem cell factor induces a rapid increase in actin stress fiber formation in melanocytes, which can be abrogated by genistein, a tyrosine kinase inhibitor, and that stem cell factor induces phosphorylation of paxillin on tyrosine residues. In contrast, stem cell factor did not regulate expression of any of the four focal contact proteins tested. These findings have implications for the models describing the mechanisms of action of stem cell factor on melanocyte adhesion and migration, and suggest that reorganization of the cytoskeleton is a primary effect of stem cell factor on human melanocytes.
12(S)-HETrE, a 12-Lipoxygenase Oxylipin of Dihomo-γ-Linolenic Acid, Inhibits Thrombosis via Gα<sub>s</sub>Signaling in Platelets (2016)

This study provides the direct evidence that an omega-6 polyunsaturated fatty acid, DGLA, inhibits injury-induced thrombosis through its 12-LOX oxylipin, 12(S)-HETrE, which strongly supports the potential cardioprotective benefits of DGLA supplementation through its regulation of platelet function. Furthermore, this is the first evidence of a 12-LOX oxylipin regulating platelet function in a Gs α subunit-linked G-protein-coupled receptor-dependent manner.

The formation mechanism of tear strips on stretched Ti-22Al-25Nb alloy sheets (2017)

This paper reports the presence of tear strips on the surface of a Ti-22Al-25Nb alloy sheet stretched at 960 °C. The test piece reveals a "bamboo"-shaped pattern on its surface, which severely affects the quality of the alloy. Microstructure analysis indicates that the formation mechanism of the tear strip is related to both the rich α<sub>2</sub> phase layer and the interfacial B2 phase dynamic recrystallization layer between the α<sub>2</sub> phase layer and the substrate metal.
The effect of a lipid hydroperoxide of arachidonic acid on the canine basilar artery (1981)

The in vivo spasmogenic capacity of a lipid hydroperoxide (15-hydroperoxy arachidonic acid: 15-HPAA) was studied in a chronic experiment using the dog. The 15-HPAA was injected into the cisterna magna (0.2 or 2 mg emulsified in bovine serum albumin solution). The changes in diameter of the basilar artery were followed by angiography, and the morphological changes were studied by electron microscopy. The cisternal injection of 0.2 mg of 15-HPAA caused a mild constriction of the basilar artery which lasted about 7 hours. The cisternal injection of 2 mg of 15-HPAA caused a biphasic constriction, the initial phase of which was a moderate narrowing lasting about 10 hours. The second phase started on the 2nd or the 3rd day after injection. The intensity of the arterial narrowing was more pronounced in the second phase than in the first. The prolonged secondary constriction of the basilar artery continued until sacrifice on the 7th day after injection. Electron microscopic study revealed a marked degenerative change in the endothelium and myonecrotic changes in the tunica media. The prolonged arterial constriction in the second phase was invariably associated with remarkable degeneration of the endothelium. On the other hand, myonecrotic changes were limited to a small number of smooth-muscle cells. The results of the present study are consonant with the hypothesis that lipid peroxidation associated with lysis of the subarachnoid clot is involved in the genesis of chronic vasospasm in subarachnoid hemorrhage.
Exploiting OxRAM Resistive Switching for Dynamic Range Improvement of CMOS Image Sensors (2017)

We present a unique application of OxRAM devices in CMOS Image Sensors (CIS) for dynamic range (DR) improvement. We propose a modified 3T-APS (Active Pixel Sensor) circuit that incorporates OxRAM in 1T-1R configuration. DR improvement is achieved by resistive compression of the pixel output signal through autonomous programming of OxRAM device resistance during exposure. We show that by carefully preconditioning the OxRAM resistance, pixel DR can be enhanced. Detailed impact of OxRAM SET-to-RESET and RESET-to-SET transitions on pixel DR is discussed. For experimental validation with specific OxRAM preprogrammed states, a 4 Kb 10 nm thick HfOx (1T-1R) matrix was fabricated and characterized. Best case, relative pixel DR improvement of ~ 50 dB was obtained for our design.
Extraction of U(VI) with unsymmetrical N-methyl-N-decylalkylamide in toluene (2005)

Summary A number of structurally related new unsymmetrical monoamides with different substituting groups, N-methyl-N-decyloctylamide (MDOA), N-methyl-N-decyldecanamide (MDDA), and N-methyl-N-decyldodecanamide (MDDOA), were synthesized. The extraction of U(VI) from nitric acid medium by the synthesized monoamides diluted with toluene was investigated. The effect of nitric acid concentration, sodium nitrate concentration, extractant concentration and temperature on the distribution ratio was studied. The stoichiometry of the main extracted species confirms to UO 2 (NO 3 ) 2 ·2A (A, amidic extractant). The values of the thermodynamic parameters were determined and the extraction reactions were found exothermic. The IR spectral study was also made of the extracted species.
Arg-735 of the 100-kDa subunit a of the yeast V-ATPase is essential for proton translocation (2001)

The vacuolar (H(+))-ATPases (V-ATPases) are ATP-dependent proton pumps that acidify intracellular compartments and pump protons across specialized plasma membranes. Proton translocation occurs through the integral V(0) domain, which contains five different subunits (a, d, c, c', and c"). Proton transport is critically dependent on buried acidic residues present in three different proteolipid subunits (c, c', and c"). Mutations in the 100-kDa subunit a have also influenced activity, but none of these residues has proven to be required absolutely for proton transport. On the basis of previous observations on the F-ATPases, we have investigated the role of two highly conserved arginine residues present in the last two putative transmembrane segments of the yeast V-ATPase a subunit (Vph1p). Substitution of Asn, Glu, or Gln for Arg-735 in TM8 gives a V-ATPase that is fully assembled but is totally devoid of proton transport and ATPase activity. Replacement of Arg-735 by Lys gives a V-ATPase that, although completely inactive for proton transport, retains 24% of wild-type ATPase activity, suggesting a partial uncoupling of proton transport and ATP hydrolysis in this mutant. By contrast, nonconservative mutations of Arg-799 in TM9 lead to both defective assembly of the V-ATPase complex and decreases in activity of the assembled V-ATPase. These results suggest that Arg-735 is absolutely required for proton transport by the V-ATPases and is discussed in the context of a revised model of the topology of the 100-kDa subunit a.

Threaded multiple path execution (1998)

This paper presents Threaded Multi-Path Execution (TME), which exploits existing hardware on a Simultaneous Multi-threading (SMT) processor to speculatively execute multiple paths of execution. When there are fewer threads in an SMT processor than hardware contexts, threaded multi-path execution uses spare contexts to fetch and execute code along the less likely path of hard-to-predict branches.This paper describes the hardware mechanisms needed to enable an SMT processor to efficiently spawn speculative threads for threaded multi-path execution. The Mapping Synchronization Bus is described, which enables the spawning of these multiple paths. Policies are examined for deciding which branches to fork, and for managing competition between primary and alternate path threads for critical resources. Our results show that TME increases the single program performance of an SMT with eight thread contexts by 14%-23% on average, depending on the misprediction penalty for programs with a high misprediction rate.
Lower bound on minimum Lee distance of algebraic–geometric codes over finite fields (2007)

Algebraic–geometric (AG) codes over finite fields with respect to the Lee metric have been studied. A lower bound on the minimum Lee distance is derived, which is a Lee-metric version of the well-known Goppa bound on the minimum Hamming distance of AG codes. The bound generalises a lower bound on the minimum Lee distance of Lee-metric BCH and Reed-Solomon codes, which have been successfully used for protecting against bitshift and synchronisation errors in constrained channels and for error control in partial-response channels.
Cone‐beam reconstruction of plate‐like specimens (1992)

Abstract An x‐ray shadow projection microscope using a scannable point source of x‐rays is under development at AMIL‐ARTS, SUNY at Buffalo. Considering the characteristics of the x‐ray microscope of AMIL‐ARTS and the limitations of Feldkamp's cone‐beam reconstruction algorithm, a general cone‐beam image reconstruction algorithm has been developed. In x‐ray microscopy, many specimens are plate‐like. The reconstruction of a plate‐like specimen appears to be a limited angle problem. A novel method is presented to reconstruct a plate‐like specimen using the general cone‐beam reconstruction algorithm. Shepp and Logan's head phantom is used in validating this method. A method for synthesizing projection data of ellipsoids is described. Typical simulation results are given.
Manufacture of embedded integrated passive components into Low Temperature Co-fired ceramic systems (1998)

The next generation of integrated electronic packaging will require higher densities, fewer external interconnects, faster clock rates, lower costs and demand higher reliability, A new emerging technology of embedding integrated passive components (IPC) in Low Temperature Co-fired Ceramics (LTCC) will allow inductor, resistor and capacitor components (RLC) to be placed within the LTCC structure resulting in increased density, reduced interconnects, increased clock speeds, reduced assembly times, thus reducing the package overall cost with increased product reliability. Rockwell Science Center cooperated with Scrantom Engineering, Inc. to test and develop an initial IPC design library.
Novel Tropane-Based Irreversible Ligands for the Dopamine Transporter (2001)

3alpha-(diphenylmethoxy)tropane (benztropine) and its analogues are tropane ring-containing dopamine uptake inhibitors that display binding and behavioral profiles that are distinct from cocaine. We previously prepared a benztropine-based photoaffinity label [125I]-(N-[4-(4'-azido-3'-iodophenyl)butyl]-3alpha-[bis(4'-fluorophenyl)methoxy]tropane, [125I]1, that covalently attached to the 1-2 transmembrane spanning region of the dopamine transporter (DAT). This was in contrast to the 4-7 transmembrane spanning region labeled by a cocaine-based photoaffinity label, [125I] 2 (RTI 82). To characterize further these different binding domains, photoaffinity ligands that had the 4'-azido-3'-iodophenyl substituent extended from the same position on the tropane ring were desirable. Thus, identification of the optimal alkyl linker between this substituent and the tropane nitrogen in the benztropine series was investigated to ultimately prepare the identical N-substituted analogue of 2. In this pursuit, the N-[4-(4'-azido-3'-iodophenyl)propyl] analogue of 3alpha-[bis(4'-fluorophenyl)methoxy]tropane (9a) was synthesized as well as two isothiocyanate analogues that do not require photoactivation (10a,b) for irreversible binding. The synthesis of these target compounds was achieved using a modification of the strategy developed for 1. Evaluation of these compounds for displacing [3H]WIN 35 428 binding at DAT in rat caudate putamen revealed that the 4'-azido-3'-iodophenylbutyl substituent, found in 1, provided optimal binding affinity and was chosen to replace the N-CH3 group on 2. Both the 4'-azido-3'-iodophenyl- and the 4'-isothiocyanatophenylbutyl analogues of 2 (25 and 26, respectively) were synthesized. Both products bound to DAT with comparable potency (IC(50) = 30 nM) to RTI 82 (2). In addition, compound 26 demonstrated wash-resistant displacement of [3H]WIN 35 428 in HEK 293 cells stably transfected with hDAT. These ligands will provide important tools for further characterizing the binding domains for tropane-based dopamine uptake inhibitors at the DAT.
