Supramolecular magnetorheological polymer gels (2006)

Abstract Novel magnetorheological fluids—supramolecular magnetorheological polymer gels (SMRPGs)— were investigated. Supramolecular polymer deposited on the surface of iron particles was suspended in the carrier fluids. The supramolecular network was obtained by metal coordination between terpyridine monomers and zinc ion. These SMRPGs had such advantages as controllable off‐state viscosity, a reduced iron particle settling rate, and stability. The viscoelastic behavior of SMRPGs with small‐ and large‐amplitude oscillatory shear was investigated using the amplitude and frequency sweep mode. The effects of strain amplitude, frequency, and magnetic field strength on the viscoelastic moduli were measured. The linear viscoelastic (LVE) strain range was obtained by the oscillation and static stress strain methods. The maximum LVE value was equal to the preyield strain point, 0.3%. Microstructural variation of SMRPG is proposed as an explanation of the rheological changes in the oscillation tests. The results of this research indicate that off–state viscosity and particle settling can be controlled by adjusting the concentration of supramolecular polymer gel. Dynamic yield stress significantly increased with an external magnetic field up to ∼23,500 Pa under a magnetic flux density of 500 mT. © 2006 Wiley Periodicals, Inc.

Homozygosity mapping with SNP arrays identifies<i>TRIM32</i>, an E3 ubiquitin ligase, as a Bardet–Biedl syndrome gene (<i>BBS11</i>) (2006)

The identification of mutations in genes that cause human diseases has largely been accomplished through the use of positional cloning, which relies on linkage mapping. In studies of rare diseases, the resolution of linkage mapping is limited by the number of available meioses and informative marker density. One recent advance is the development of high-density SNP microarrays for genotyping. The SNP arrays overcome low marker informativity by using a large number of markers to achieve greater coverage at finer resolution. We used SNP microarray genotyping for homozygosity mapping in a small consanguineous Israeli Bedouin family with autosomal recessive Bardet-Biedl syndrome (BBS; obesity, pigmentary retinopathy, polydactyly, hypogonadism, renal and cardiac abnormalities, and cognitive impairment) in which previous linkage studies using short tandem repeat polymorphisms failed to identify a disease locus. SNP genotyping revealed a homozygous candidate region. Mutation analysis in the region of homozygosity identified a conserved homozygous missense mutation in the TRIM32 gene, a gene coding for an E3 ubiquitin ligase. Functional analysis of this gene in zebrafish and expression correlation analyses among other BBS genes in an expression quantitative trait loci data set demonstrate that TRIM32 is a BBS gene. This study shows the value of high-density SNP genotyping for homozygosity mapping and the use of expression correlation data for evaluation of candidate genes and identifies the proteasome degradation pathway as a pathway involved in BBS.
Strained silicon NMOS with nickel-silicide metal gate (2004)

Strained Si NMOS transistors with Lgate down to 35 nm were fabricated using NiSi as a metal gate electrode material for the first time. Compared to poly gate devices, NiSi metal gate devices showed further enhanced performance with good control of short channel effects and no degradation in gate oxide integrity.
Efficient Authentication for Mobile and Pervasive Computing (2012)

With today's technology, many applications rely on the existence of small devices that can exchange information and form communication networks. In a significant portion of such applications, the confidentiality and integrity of the communicated messages are of particular interest. In this work, we propose two novel techniques for authenticating short encrypted messages that are directed to meet the requirements of mobile and pervasive applications. By taking advantage of the fact that the message to be authenticated must also be encrypted, we propose provably secure authentication codes that are more efficient than any message authentication code in the literature. The key idea behind the proposed techniques is to utilize the security that the encryption algorithm can provide to design more efficient authentication mechanisms, as opposed to using standalone authentication primitives.
Orientation selection by zone-melting silicon films through planar constrictions (1982)

Recrystallization of encapsulated Si films on SiO2 by zone-melting produces films composed of several grains approximately 1 mm wide and extending the length of the scan. Within grains there are sub-boundaries. We report a technique for producing recrystallized Si films of a single orientation. The technique consists of patterning polysilicon with a narrow, planar constriction and passing a molten zone through it so that only one orientation propagates beyond the constriction. We also show that sub-boundaries can be eliminated in the constriction.
Embedded Ferroelectric Memory Technology With Completely Encapsulated Hydrogen Barrier Structure (2005)

A 0.18-/spl mu/m system LSI embedded ferroelectric memory (FeRAM) operating at a very low voltage has been developed for the first time. The low-voltage operation has been attained by newly developed stacked ferroelectric capacitors completely encapsulated by hydrogen barriers, which enable us to eliminate hydrogen reduction of the ferroelectric thin film during the back end of the line process including FSG, tungsten CVD (W-CVD), and plasma CVD SiN (p-SiN) passivation. A fabricated 1-Mbit one-transistor one-capacitor SrBi/sub 2/(Ta/sub x/Nb/sub 1-x/)/sub 2/O/sub 9/ (SBTN)-based embedded FeRAM operates at a low voltage of 1.1 V and ensures the endurance cycles up to 10/sup 12/ at 85/spl deg/C and the data retention time up to 1000 h at 125/spl deg/C, which is the most promising for mass production of 0.18-/spl mu/m low-power system LSI-embedded FeRAM and beyond.
Enhanced light output of GaN-based near-UV light-emitting diodes by using nanopatterned indium tin oxide electrodes (2006)

We report on the enhancement of the light output of near-UV (298 nm) GaN-based light-emitting diodes (LEDs) by using nanopatterned indium tin oxide (ITO) p-type contact layers. One-dimensional (1D) and two-dimensional (2D) nanopatterns are defined using a TiO2 nano-mask, fabricated by means of a surface relief grating technique. The LEDs fabricated with the 1D and 2D nanopatterned p-type electrodes produce higher output powers by 33–48% (at 20 mA) as compared to those fabricated with the unpatterned contacts. The pattern-induced improvement of the output power is described in terms of the formation of the sidewalls of p-type electrodes.
A Multicenter, Randomized, Double‐Blind, Placebo‐Controlled Trial of Intravenous Ibuprofen (IV‐Ibuprofen) in the Management of Postoperative Pain Following Abdominal Hysterectomy (2010)

This study demonstrated that i.v.-ibuprofen is an effective analgesic medication that is safe and well tolerated when administered as an 800 mg dose every 6 hours in patients undergoing total abdominal hysterectomy surgery.
BMHP1-Derived Self-Assembling Peptides: Hierarchically Assembled Structures with Self-Healing Propensity and Potential for Tissue Engineering Applications (2011)

Self-assembling peptides (SAPs) are rapidly gaining interest as bioinspired scaffolds for cell culture and regenerative medicine applications. Bone Marrow Homing Peptide 1 (BMHP1) functional motif (PFSSTKT) was previously demonstrated to stimulate neural stem cell (NSC) viability and differentiation when linked to SAPs. We here describe a novel ensemble of SAPs, developed from the BMHP1 (BMHP1-SAPs), that spontaneously assemble into tabular fibers, twisted ribbons, tubes and hierarchical self-assembled sheets: organized structures in the nano- and microscale. Thirty-two sequences were designed and evaluated, including biotinylated and unbiotinylated sequences, as well as a hybrid peptide-peptoid sequence. Via X-ray diffraction (XRD), CD, and FTIR experiments we demonstrated that all of the BMHP1-SAPs share similarly organized secondary structures, that is, β-sheets and β-turns, despite their heterogeneous nanostructure morphology, scaffold stiffness, and effect over NSC differentiation and survival. Notably, we demonstrated the self-healing propensity of most of the tested BMHP1-SAPs, enlarging the set of potential applications of these novel SAPs. In in vitro cell culture experiments, we showed that some of these 10-mer peptides foster adhesion, differentiation, and proliferation of human NSCs. RGD-functionalized and hybrid peptide-peptoid self-assembling sequences also opened the door to BMHP1-SAP functionalization with further bioactive motifs, essential to tailor new scaffolds for specific applications. In in vivo experiments we verified a negligible reaction of the host nervous tissue to the injected and assembled BMHP1-SAP. This work will pave the way to the development of novel SAP sequences that may be useful for material science and regenerative medicine applications.
Analysis of Upstream Region of Nicotianamine Synthase Gene from Arabidopsis thaliana: Presence of Putative ERE-like Sequence (2001)

Nicotianamine (NA) is present in all plants so far examined, and is thought to chelate transition metal ions. Previously, we isolated three nicotianamine synthase (NAS) genes of Arabidopsis thaliana (AtNAS1, 2, and 3) and showed that each NAS gene is differentially expressed. Deletion analysis of the 5' flanking region of AtNAS3 found a putative ethylene-responsive sequence, ATTTTCAAA.
Method for creating location-specific audio textures (2014)

An approach is proposed for creating location-specific audio textures for virtual location-exploration services. The presented approach creates audio textures by processing a small amount of audio recorded at a given location, providing a cost-effective way to produce a versatile audio signal that characterizes the location. The resulting texture is non-repetitive and conserves the location-specific characteristics of the audio scene, without the need of collecting large amount of audio from each location. The method consists of two stages: analysis and synthesis. In the analysis stage, the source audio recording is segmented into homogeneous segments. In the synthesis stage, the audio texture is created by randomly drawing segments from the source audio so that the consecutive segments will have timbral similarity near the segment boundaries. Results obtained in listening experiments show that there is no statistically significant difference in the audio quality or location-specificity of audio when the created audio textures are compared to excerpts of the original recordings. Therefore, the proposed audio textures could be utilized in virtual location-exploration services. Examples of source signals and audio textures created from them are available at http://www.cs.tut.fi/~heittolt/audiotexture .
A Doppler Radar for Continuous Remote Measurement of River Ice Velocity (1995)

Abstract : River ice velocity measurements are fundamental to analyses of river ice dynamics. Ice velocity measurement with a continuous-wave Doppler radar system having real-time data acquisition and digital signal processing capability was evaluated during a river breakup and a frazil run on the Connecticut River. This system can be rapidly deployed, requires minimal operator interaction, will continuously acquire, process, store, and display ice velocity data and does not depend on visibility conditions. In parallel, video records of ice motion were obtained at the same location for later manual processing and comparison with the radar results. We describe the Doppler radar system and obtain bounding estimates of possible measurement errors. The principal error in Doppler ice velocity measurement is due to the beam width of the radar antenna, and an analytical method is developed to minimize this error. Measured ice velocities ranged from 1 to 2.5 m/s during the river breakup and from 0.5 to 0.65 m/s in the frazil run. Quantitative comparisons between the radar and video results show fundamental agreement between these measurement methods, and demonstrate that Doppler radar is an effective, efficient, and precise tool for obtaining river ice velocities over the full range of possible ice and velocity conditions.

Modeling the Appearance of the Round Brilliant Cut Diamond: An Analysis of Brilliance (1998)

Of the “four C’s,”cut has historically been the most complex to understand and assess. This article presents a three-dimensional mathematical model to study the interaction of light with a fully faceted, colorless, symmetrical roundbrilliant-cut diamond. With this model, one can analyze how various appearance factors (brilliance, fire, and scintillation) depend on proportions. The model generates images and a numerical measurement of the optical efficiency of the round brilliant—called weighted light return (WLR)—which approximates overall brilliance. This article examines how WLR values change with variations in cut proportions, in particular crown angle, pavilion angle, and table size. The results of this study suggest that there are many combinations of proportions with equal or higher WLR than “Ideal” cuts. In addition, they do not support analyzing cut by examining each proportion parameter independently. However, because brilliance is just one aspect of the appearance of a faceted diamond, ongoing research will investigate the added effects of fire and scintillation.
Fertilization and Development of Eggs of the Sea Urchin <i>Lytechinus variegatus</i> Maintained on an Extruded Feed (2000)

Abstract Sea urchin eggs are used extensively as models for studies in developmental and molecular biology. Developing aquaculture techniques and facilities for sea urchins would facilitate their use for this purpose and for production of young sea urchins for stock enhancement. A basic requirement for the aqua‐culture of sea urchins is the availability of a feed that predictably produces eggs of a consistent, high quality. We tested an extruded feed with Lyrechinus variegatus for this purpose. Lytechinus variegatus (mean horizontal diameter 55 mm, 75 g wet weight) were collected in April 1998. Nine individuals were maintained in each of four aquaria with closed, recirculating filtered sea water. They were fed approximately 1 g extruded feedindividual per week. All feed was consumed. The mean weight of the sea urchins changed little with this feeding regime. The sea urchins spawned spontaneously on a monthly basis during water changes. Four females in February and one in March were spawned by injection with potassium chloride. Fertilization was 99–100% successful in each case. Egg diameters from these spawnings and a spontaneous spawning in April ranged from 102 × 6 to 128 × 1 μm. Gastrulation occurred in <20 h and metamorphosis after 22 to 37 d. Newly metamorphosed juveniles ranged in size from 435 × 38 to 473 × 56 μm. Egg size, larval size, the chronology of embryonic and larval development, and size of newly metamorphosed juveniles are similar to those obtained from field individuals reported in the literature. These results indicate that a predictable production of high quality eggs by sea urchins under controlled conditions in the laboratory with a prepared feed is feasible.
Ferrocene‐Based Planar Chiral Imidazopyridinium Salts for Catalysis (2015)

Planar chirality remains an underutilized control element in asymmetric catalysis. Factors that have limited its broader application in catalysis include poor catalyst performance and difficulties associated with the economical production of enantiopure planar chiral compounds. The construction of planar chiral azolium salts that incorporate a sterically demanding iron sandwich complex is now reported. Applications of this new N-heterocyclic carbene as both an organocatalyst and a ligand for transition-metal catalysis demonstrate its unprecedented versatility and potential broad utility in asymmetric catalysis.
Development of a loop detector simulator (LOOPSIM) for in‐laboratory traffic research and education (2008)

Abstract This article describes a LOOP detector SIMulator (LOOPSIM) system designed for traffic research and education. LOOPSIM is capable of simulating calls from loop detectors and testing algorithms executable in the controller. It can also be used to simulate different patterns of traffic streams and replay collected loop event data. With the aid of LOOPSIM, researchers and educators can designate traffic characteristics in line with the purpose of the testing or teaching. © 2008 Wiley Periodicals, Inc.

Hard ferromagnetism in melt-spun Hf2Co11B alloys (2012)

Hard ferromagnetic behavior is reported for crystalline Hf2Co11B produced by melt-spinning. For the highest-performing material, remanent magnetization, intrinsic coercive field, and maximum energy product at room temperature are 6.2 kG, 4.5 kOe, and 6.7 MGOe, respectively. This is the highest reported energy product for this class of alloys, and is about half that of optimized Nd2Fe14B ribbons. The Curie temperature of both crystalline and amorphous Hf2Co11B is near 770 K. The results suggest further optimization of magnetic properties should be attainable, and indicate Hf2Co11B to be a promising material for rare-earth-free permanent magnets.

Functional relevance of specific interactions between herpes simplex virus type 1 ICP4 and sequences from the promoter-regulatory domain of the viral thymidine kinase gene (1990)

The herpes simplex virus (HSV) type 1 immediate-early regulatory protein ICP4 is required for induced expression of HSV early and late genes, yet the mechanism by which this occurs is not known. We examined the promoter and flanking sequences of the HSV early gene that encodes thymidine kinase for the ability to interact specifically with ICP4 in gel retardation assays. Protein-DNA complexes containing ICP4 were observed with several distinct regions flanking the tk promoter. cis-Acting elements that interact with cellular transcription factors were apparently not required for these interactions to form. Purified ICP4 formed protein-DNA complexes with fragments from these regions, and Southwestern (DNA-protein blot) analysis indicated that the interaction between ICP4 and these sequences can be direct. None of the tk sequences that interact with ICP4 contains a consensus binding site for ICP4 (S. W. Faber and K. W. Wilcox, Nucleic Acids Res. 14:6067-6083, 1986), reflecting the ability of ICP4 to interact with more than one DNA sequence. A mutated ICP4 protein expressed from the viral genome that retains the ability to bind to a consensus binding site but does not bind specifically to the identified sites flanking the tk promoter results in induced transcription of the tk gene. These data support hypotheses for ICP4-mediated transactivation of the tk promoter in Vero cells that do not require the intrinsic ability of ICP4 to bind specifically in or near the promoter of the tk gene.
Immunoradiometric assay to measure the binding of a specific inhibitor to tissue-type plasminogen activator. (1985)

A functional, immunoradiometric assay for a specific plasminogen activator inhibitor (PAI) was developed. This assay was based on the ability of the PAI to bind rapidly and strongly to immobilized tissue-type plasminogen activator (tPA). The extent of binding was quantified by incubating the PAI-tPA complex first with rabbit antiserum to the PAI and then with 125I-labeled goat anti-rabbit IgG. The interaction between tPA and the PAI was rapid, time- and concentration-dependent, sensitive over a broad range of PAI concentrations (1 to 100 ng/ml), and competed by urokinase but not streptokinase. The widespread application of this new technique was indicated by its ability to detect an immunologically related PAI not only in a number of other cell types, but also in platelets from which it can be released by thrombin, and in blood. This assay thus provides a quantitative approach for assessing the role of this PAI in a variety of fibrinolytic processes.
Nonlinear Properties of Chalcogenide Glass Fibers (2010)

Chalcogenide glasses have demonstrated high third-order Kerr (Χ (3) ) nonlinearities up to 1000x higher than silica glass which make them attractive for applications such as nonlinear switching, optical regeneration, Raman amplification, parametric amplification, and supercontinuum generation. Poling of chalcogenide glasses to induce an effective second order (Χ (2) ) nonlinearity has also been demonstrated and opens the possibility for the use of poled glass waveguides for applications such as frequency conversion or electro-optic modulation. Stimulated Brillouin scattering (SBS) has also been investigated in As 2 S 3 and As 2 Se 3 single-mode fibers. The threshold intensity for the stimulated Brillouin scattering process was measured and used to estimate the Brillouin gain coefficient. Preliminary results indicate record high values for the figure of merit and theoretical gain, compared to silica, which bodes well for slow-light based applications in chalcogenide fibers.
