Synthesis, structural characterization and reactivity of triosmium carbonyl clusters containing oxime ligands (2002)

Reaction of [Os3(CO)11(NCMe)] with phenyl 2-pyridyl ketoxime produced the clusters [Os3(CO)8{μ-η3-ONCPh(NC5H4)}2] 1 and [Os3H(CO)11{η2-ONCPh(NC5H4)}] 2 in 4 and 17% yields, respectively. Oxidative addition of the oximes to the clusters with O–H bond cleavage and the loss of labile acetonitrile groups, and in the case of complex 1 decarbonylation, are observed. Cluster 2 possesses an open linear metal skeleton attached to both the pyridine nitrogen and oximato nitrogen on one terminal Os atom. Heating 2 in refluxing toluene gave [Os3(μ-H)(CO)9{µ-η3-ONCPh(NC5H4)}] 3 in 13% yield. Treatment of a CH2Cl2 solution of [Os3(CO)10(NCMe)2] with phenyl 2-pyridyl ketoxime at ambient conditions afforded the bridging oximato clusters 1 and 3 in moderate yields. Cluster 3 and 1 equiv. of phenyl 2-pyridyl ketoxime in refluxing toluene led to conversion to clusters 1 and [Os3(CO)8{μ-η3-ONCPh(NC5H4)} {μ-η2-N(H)CHPh(NC5H4)}] 4 in 12 and 16% yields, respectively. In cluster 4, one of the oximato moieties is deoxygenated with N–O bond cleavage. Treatment of another oxime ligand, benzophenone oxime, with [Os3(CO)10(NCMe)2] gave [Os3(μ-H)(CO)10{μ-η2-ONCPh2}] 5 in moderate yield. On thermolysis of 5 in toluene, [Os3(μ-H)2(CO)9{μ-η3-ONCPh(C6H4)}] 6 and [Os3(CO)10(μ-OH){μ-NCPh2}] 7 were isolated in 27 and 21% yields, respectively. The oxime ligand in 6 is converted to a tridentate ligand. In addition to the μ-η2-oximato N–O bridge, the phenyl carbon on the ligand coordinates to the cluster core by ortho-metallation. Cluster 5 isomerizes thermally to 7, which is formed by oxidative addition of the oxime with N–O bond cleavage. A μ4-oxo hexaosmium cluster, [Os6(CO)16(μ4-O){μ-η3-NCPh(C6H4)}2] 8, was isolated in low yield upon refluxing 5 in octane. Vacuum pyrolysis of 5 in 140 °C yielded a pentaosmium carbonyl cluster, [Os5(CO)15{μ-η3-NCPh(C6H4)}] 9. All these clusters have been fully characterized by both spectroscopic and crystallographic techniques.

Importance of IP Alias Resolution in Sampling Internet Topologies (2007)

Internet measurement studies utilize traceroute-based path traces to build representative Internet maps. These maps are then used to analyze various topological characteristics of the Internet. IP alias resolution is an important step in building a map from a set of collected path traces. In this paper, we study the impact of incomplete IP alias resolution on Internet measurement studies. Using a set of synthetic topologies and a genuine topology map, we experimentally show that the accuracy/completeness of alias resolution has an important effect on the observed topological characteristics. The results obtained in this work point out the importance of IP alias resolution and call for further research in alias resolution.

Cytokinin-mediated control of leaf longevity by AHK3 through phosphorylation of ARR2 in <i>Arabidopsis</i> (2006)

Cytokinins are plant hormones with profound roles in growth and development, including control of leaf longevity. Although the cytokinin signal is known to be perceived by histidine kinase receptors, the underlying molecular mechanism and specificity of the receptors leading to delayed leaf senescence have not yet been elucidated. Here, we found that AHK3, one of the three cytokinin receptors in Arabidopsis, plays a major role in controlling cytokinin-mediated leaf longevity through a specific phosphorylation of a response regulator, ARR2. This result was obtained through identification of a gain-of-function Arabidopsis mutant that shows delayed leaf senescence because of a missense mutation in the extracellular domain of AHK3. A loss-of-function mutation in AHK3, but not of the other cytokinin receptors, conferred a reduced sensitivity to cytokinin in cytokinin-dependent delay of leaf senescence and abolished cytokinin-dependent phosphorylation of ARR2. Consistently, transgenic overexpression of wild-type, but not an unphosphorylatable mutant ARR2, led to delayed senescence of leaves.
Measurement of Combustion Gas Temperature of Internal Combustion Engine by Use of Ultrasonic Wave (1971)

The frequency of a sound wave is changed from the original one by passing through the rapidly temperature changing gas. The new technique for measuring the varying gas temperature by detecting the frequency change of the passing ultrasonic wave was applied to the temperature measurement of combustion gas in a four cycle reciprocating engine. For the check of the measured temperature using this new technique, the measured sound velocity was compared with that by the conventional direct sound velocity measuring method. As a result of the experiment, it was concluded that the new measuring technique was reliable.
Synthetic Training for Accurate 3D Human Pose and Shape Estimation in the Wild (2020)

This paper addresses the problem of monocular 3D human shape and pose estimation from an RGB image. Despite great progress in this field in terms of pose prediction accuracy, state-of-the-art methods often predict inaccurate body shapes. We suggest that this is primarily due to the scarcity of in-the-wild training data with diverse and accurate body shape labels. Thus, we propose STRAPS (Synthetic Training for Real Accurate Pose and Shape), a system that utilises proxy representations, such as silhouettes and 2D joints, as inputs to a shape and pose regression neural network, which is trained with synthetic training data (generated on-the-fly during training using the SMPL statistical body model) to overcome data scarcity. We bridge the gap between synthetic training inputs and noisy real inputs, which are predicted by keypoint detection and segmentation CNNs at test-time, by using data augmentation and corruption during training. In order to evaluate our approach, we curate and provide a challenging evaluation dataset for monocular human shape estimation, Sports Shape and Pose 3D (SSP-3D). It consists of RGB images of tightly-clothed sports-persons with a variety of body shapes and corresponding pseudo-ground-truth SMPL shape and pose parameters, obtained via multi-frame optimisation. We show that STRAPS outperforms other state-of-the-art methods on SSP-3D in terms of shape prediction accuracy, while remaining competitive with the state-of-the-art on pose-centric datasets and metrics.

Distance bounding protocols for RFID enhanced by using void‐challenges and analysis in noisy channels (2008)

Abstract RFID systems are vulnerable to different attacks related to the location; distance fraud attack, relay attack and terrorist attack. The main countermeasure against these attacks is the use of protocols capable of measuring the round trip time of single challenge‐response bit. In this paper, we consider a modification of these protocols applying a new feature; the ‘void challenges’. This way, the success probability for an adversary to access to the system decreases. We use as reference‐point the most popular of this kind of protocols, the Hancke and Kuhn's protocol, to show the improvements achieved when different cases are analysed.

Combining multiple nondestructive inspection images with a generalized additive model (2008)

In this paper, multiple nondestructive inspection (NDI) images are combined with a generalized additive model to achieve a more precise and reliable assessment of hidden corrosion in aircraft lap joints. Two inspection techniques are considered in this study. One is the conventional multi-frequency eddy current testing technique and the other is the pulsed eddy current technique. To characterize the thickness loss or equivalently to achieve a quantitative measure of corrosion, multiple NDI images are fused to produce a thickness map that reflected the amount of corrosion damage. These results are further compared with corresponding digital x-ray thickness maps, which are obtained by mapping the remaining thickness after the specimen is dissembled and all the corrosion products are cleaned. Experimental results demonstrate that the proposed algorithms outperform the traditional calibration method aligned with a single testing approach.

<title>Single epitaxial structure for the integration of lasers with heterojunction bipolar transistors</title> (1994)

Heterojunction bipolar transistors (HBTs) are capable of producing very high speed digital integrated circuits operating as high as 40 GHz. In this paper we introduce a potentially low cost technique of monolithically integrating in-plane lasers with HBT circuits. A multifunctional epitaxial structure is used which is essentially the same as that for a standard high-speed HBT with modifications made to allow for efficient light amplification. Unlike previous multifunctional epitaxial structures, compromise in the transistor's performance is minimal. The schematic energy band diagrams of the HBT/laser structure biased as an HBT and laser are depicted. Light amplification is achieved by forward biasing the HBT's base- collector junction. The optical gain media is placed in the GaAs collector and consists of strained InGaAs quantum wells (QWs). Under normal HBT operation, the base-collector junction is reverse biased and serves as a sink for electrons which have diffused across the base. To confine electronic carries to the gain region when this junction is forward biased, the subcollector and base consist of a wider bandgap AlGaAs relative to the GaAs collector.
Variability of Fusion Vergence Measurements in Heterophoria (2016)

Exophoric children have reduced convergence break points when compared with orthophoric and esophoric children. Vergence measurements, taking into consideration the baseline heterophoria, give important information about the ability of the patient to increase their vergence demand and maintain ocular alignment.
CPSF recognition of an HIV-1 mRNA 3'-processing enhancer: multiple sequence contacts involved in poly(A) site definition. (1995)

The endonucleolytic cleavage and polyadenylation of a pre-mRNA in mammalian cells requires two cis-acting elements, a highly conserved AAUAAA hexamer and an amorphous U- or GU-rich downstream element, that together constitute the "core" poly(A) site. The terminal redundancy of the HIV-1 pre-mRNA requires that the processing machinery disregard a core poly(A) site at the 5' end of the transcript, and efficiently utilize an identical signal that resides near the 3' end. Efficient processing at the 3' core poly(A) site, both in vivo and in vitro, has been shown to require sequences 76 nucleotides upstream of the AAUAAA hexamer. In this report we demonstrate that this HIV-1 upstream element interacts directly with the 160-kD subunit of CPSF (cleavage polyadenylation specificity factor), the factor responsible for the recognition of the AAUAAA hexamer. The presence of the upstream element in the context of the AAUAAA hexamer directs the stable binding of CPSF to the pre-mRNA and enhances the efficiency of poly(A) addition in reactions reconstituted with purified CPSF and recombinant poly(A) polymerase. Our results indicate that the dependence of HIV-1 3' processing on upstream sequences is a consequence of the suboptimal sequence context of the AAUAAA hexamer. We suggest that poly(A) site definition involves the recognition of multiple heterogeneous sequence elements in the context of the AAUAAA hexamer.
Transgenic rescue of hemolytic anemia due to red blood cell pyruvate kinase deficiency (2007)

These results indicate that overexpression of the wild-type PK gene in mutant erythroid cells ameliorates both erythroid apoptosis and the shortened red blood cell lifespan observed in PK mutant mice. It is likely that the level of transgene expression required to achieve evident therapeutic effects should be equivalent to or more than that of the endogenous PK gene. This gene-addition strategy may be suitable for clinical application if there is a high level of transgene expression of R-PK in erythroid progenitors/red blood cells.
Halo Skeletal Fixation: Techniques of Application and Prevention of Complications (1996)

The halo skeletal fixator provides the most rigid cervical immobilization of all orthoses. However, complications such as pin loosening and infection are common. Appreciation of local anatomy and adherence to established application guidelines should minimize pin-related problems. A relatively safe zone for anterior pin placement is located 1 cm above the orbital rim and superior to the lateral two thirds of the orbit. Posterior pin-site locations are less critical; positioning on the posterolateral aspect of the skull, diagonal to the contralateral anterior pins, is generally desirable. Pins should enter the skull perpendicular to the cortex, with the ring or crown sitting below the widest portion of the skull and passing about 1 cm above the helix of the ear. Pins are inserted at a torque of 8 in-lb and retightened once to 8 in-lb at 48 hours. A loose pin can be retightened to 8 in-lb if resistance is met; otherwise, a loose pin should be replaced at a nearby site. Superficially infected pins are managed with local pin care and oral antibiotics. Persistent or severe infections require pin replacement to a nearby site, parenteral antibiotic therapy, and incision and drainage as needed. In-ability to maintain acceptable cervical reduction with a halo fixator is an indication for alternative treatment, such as internal fixation or traction.
Applications of ultrasonic skin permeation in transdermal drug delivery (2008)

Transdermal ultrasound-mediated drug delivery has been studied as a method for needle-less, non-invasive drug administration. Potential obstacles include the stratum corneum, which is not sufficiently passively permeable to allow effective transfer of many medications into the bloodstream without active methods. A general review of the transdermal ultrasound drug delivery literature has shown that this technology offers promising potential for non-invasive drug administration. Included in this review are the reported acoustic parameters used for achieving delivery, along with the known intensities and exposure times. Ultrasound mechanisms are discussed as well as spatial field characteristics. Accurate and precise quantification of the acoustic field used in drug delivery experiments is essential to ensure safety versus efficacy and to avoid potentially harmful bioeffects.
The Ballistic Impact Characteristics of Woven Fabrics Impregnated with a Colloidal Suspension and Flattened Rolls (2010)

This research investigated the ballistic impact characteristics of KM2 Kevlar fabrics and Dyneema UD for personnel body armour using two stage gas gun. The neat KM2 Kevlar fabrics were compared with those impregnated with shear thickening fluid(STF) which showed to absorb much energy up to a velocity of 300m/s. Also studied are the effects of projectile shapes on the energy absorbing in fabrics. We observed that the fiber pull out distance without breaking is important for ballistic energy absorption. We devised an efficient ballistic energy absorbing mechanism at high velocity range by adopting flattened roll design of Dyneema UD. The suggested hybrid design composed of flattened roll and KM2 fabric impregnated with STF with stitching had advantage of 15~20% areal density reduction compared with neat KM2 fabric design.
Consensus of high order linear multi-agent systems using output error feedback (2009)

In this paper, we study the consensus problem of multi-agent systems in which each agent adopts the same linear model that can be of any order. We consider the case where only the relative output error between the neighboring agents can be measured. In order to solve the consensus problem, two kinds of decentralized control laws are designed. We first show that a static output error feedback control can solve the consensus problem if some further constraints on the system model is imposed. Then we use an observer based approach to design a dynamic output error feedback consensus control. We note that with the observer based approach, some information exchange between the agents is needed unless the associated adjacent graph is completely connected.
N-Methyl-d-aspartate Receptor- and Calpain-mediated Proteolytic Cleavage of K+-Cl− Cotransporter-2 Impairs Spinal Chloride Homeostasis in Neuropathic Pain (2012)

Loss of synaptic inhibition by γ-aminobutyric acid and glycine due to potassium chloride cotransporter-2 (KCC2) down-regulation in the spinal cord is a critical mechanism of synaptic plasticity in neuropathic pain. Here we present novel evidence that peripheral nerve injury diminishes glycine-mediated inhibition and induces a depolarizing shift in the reversal potential of glycine-mediated currents (E(glycine)) in spinal dorsal horn neurons. Blocking glutamate N-methyl-D-aspartate (NMDA) receptors normalizes synaptic inhibition, E(glycine), and KCC2 by nerve injury. Strikingly, nerve injury increases calcium-dependent calpain activity in the spinal cord that in turn causes KCC2 cleavage at the C terminus. Inhibiting calpain blocks KCC2 cleavage induced by nerve injury and NMDA, thereby normalizing E(glycine). Furthermore, calpain inhibition or silencing of μ-calpain at the spinal level reduces neuropathic pain. Thus, nerve injury promotes proteolytic cleavage of KCC2 through NMDA receptor-calpain activation, resulting in disruption of chloride homeostasis and diminished synaptic inhibition in the spinal cord. Targeting calpain may represent a new strategy for restoring KCC2 levels and tonic synaptic inhibition and for treating chronic neuropathic pain.
The role of foundational ontologies for conceptual modeling and domain ontology representation (2006)

In recent years, there has been a growing interest in the development and use of domain ontologies, strongly motivated by the semantic Web initiative. However, as we demonstrate in this paper, an approach for ontology representation uniquely based on the modeling languages adopted in the semantic Web is insufficient to address a number of semantic interoperability problems that arise in concrete application scenarios. The main objective of this paper is to advocate in favor of an approach for conceptual modeling, in general, and domain ontology representation, in particular, in which lightweight modeling languages such as OWL and standard UML are complemented by modeling languages and methodologies based on theoretically principled foundational ontologies
