Multiplanar 4D strain analysis with spatial mapping to 3D LGE quantification: relationships in chronic Ischemic Cardiomyopathy (2015)

was 28.2±7.5 years with LVEF of 61.8±7.4%, all segments with no LGE. Segmental strain analysis using all 4 metrics showed substantial reductions in mean peak amplitude for ICM segments without LGE versus healthy controls (p<0.05). Within the ICM cohort, LGE≥50% segments showed reduced strain amplitudes versus segments without LGE (mean reduction 29.0 ±13.6% - Figure 2) for all strain metrics (p<0.05). Significant difference was found between LGE<50% and LGE≥50% segments. ROC analysis identified AUCs for detection of LGE≥50% of 0.63, 0.28, 0.62, and 0.62, respectively. Using optimal cut-offs, corresponding sensitivity was 59.8%, 32.5%, 58.5%, and 57.7%, while specificity was 59.1, 32.3%, 58.2 and 57.8%. AUCs for identifying viable (LGE<50%) segments were 0.37, 0.72, 0.38 and 0.38, the greatest sensitivity and specificity being 68.5% and 67.5%, respectively, for Radial Strain. The PPV and NPV achieved for identifying a viable segment were 90.6% and 32.0%, respectively. Conclusions In chronic ICM, spatially matched 4D strain/LGE analysis identifies reduced strains in scarred segments, however also significant pathology in remote tissue compared to healthy controls. The latter limits the NPV of strain analysis for identifying non-scarred segments. However, this study demonstrates a novel capacity of CMR-based strain quantification to characterize the global health of remote tissue. As such, this provides a novel imaging marker for the quantification of remote tissue remodeling / functional integrity and warrants investigation for its prognostic value in ICM.
Unraveling the Structure and Binding Energy of Adsorbed CO2/H2O on Amine Sorbents (2020)

One critical issue in the design of amine-based sorbents and solvents for next-generation CO2 capture technology is the effect of H2O on the behavior of adsorbed CO2. To gain an insight into the effect of the complex interaction between adsorbed CO2/H2O on the amine efficiency and binding strength of the adsorbed species, the surface and subsurface molecular interactions of H2O, CO2, and H2O + CO2 were studied over tetraethylenepentamine (TEPA) films by in situ infrared spectroscopy (IR), mass spectrometry, and density functional theory (DFT). The TEPA films were used because they emulate the immobilized amine on solid amine sorbents. The H2O molecules in the TEPA film serve as a proton acceptor during the coadsorption of CO2 and H2O, allowing the formation of hydronium carbamate and producing a ratio of 1:1 for the CO2/amine site. The DFT-simulated structures and IR spectrum enabled the assignment of the experimental IR spectrum for hydronium carbamate that was produced during the interaction of CO2 on the premixed TEPA/H2O and TEPA/D2O films. Adsorption of CO2 on a TEPA/H2O (weight ratio of 5:1) film produced strongly adsorbed species: a hydrated hydronium carbamate with a binding energy >−130 kJ/mol and a cluster of the water molecule with a binding energy >−180 kJ/mol, which endothermically desorbed from the TEPA/H2O film at temperature above 90 °C. In addition to these strongly adsorbed species embedded in the bulk of the TEPA/H2O film, weakly adsorbed CO2 + H2O species (desorbed at temperature below 70 °C) on the surface of TEPA film were elucidated to be single H2O molecule dispersed on amine sites and water coordinated zwitterion. H2O controlled the CO2 capture capacity, the binding energy of adsorbed CO2/H2O, and their adsorption/desorption kinetics through the intermolecular interactions of CO2 and H2O with the specific spatial locations of amine sites. The observation of weakly adsorbed CO2/H2O suggests the spatial arrangements of amine sites in the amine sorbents and solvents can be used to fine-tune their regeneration temperature.
Velocity measurements in flowing fluids by MNR (1974)

A straightforward NMR technique which determines the spatial profile of the velocity in laminar fluid flow is described. An improved method is also presented for directly measuring the velocity distribution function. The methods employ a linear magnetic field gradient, which introduces a spatial variation to the nuclear Larmor frequency. Experimental results for the velocity profile of water flow in circular and rectangular pipes are presented, as well as for the velocity distribution function in a circular pipe.
Diagnostic and disease severity determination criteria for hydroa vacciniforme lymphoproliferative disorders and severe mosquito bite allergy (2023)

Hydroa vacciniforme lymphoproliferative disorder (HV-LPD) and severe mosquito bite allergy (SMBA) are both cutaneous forms of Epstein-Barr virus (EBV)-associated T/natural killer (NK) cell LPDs and are closely related to chronic active EBV disease (CAEBV) and EBV-associated hemophagocytic lymphohistiocytosis (EBV-HLH). HV-LPD is further divided into classic HV, a benign subtype mediated by EBV-positive γδT cells, and systemic HV, another life-threatening subtype mainly associated with EBV-positive αβT or γδT cells. The vast majority of patients with SMBA have increased numbers of EBV-infected NK cells in the blood. Clinical symptoms of HV-LPD and SMBA often overlap in the same patient and may progress to more serious disease conditions equivalent to the systemic form of CAEBV. To define the disease spectrum of HV-LPD and SMBA, we propose the diagnostic criteria and the determination criteria for disease severity. The proposed diagnostic criteria are consistent with those for CAEBV and EBV-HLH in the guidelines for the management for CAEBV and related disorders 2023.

Building tensile structures with flying machines (2013)

This paper presents the building of lightweight tensile structures with quadrocopters. The construction elements (such as ropes, cables, and wires) in this kind of structure are subject to tension forces. This paper identifies the basic building elements (nodes, links) required for the construction of tensile structures, and translates them into meaningful trajectories for quadrocopters. The use of a library of building elements is suggested. Hybrid force-position control strategies based on admittance control are exploited. Prototypical tensile structures are built by quadrocopters to validate the proposed approach. An accompanying video shows the building process.
Botulinum A Toxin for (Expressionistic) Ptosis Overcorrection After Frontalis Sling (1992)

Botulinum A toxin was injected into the frontalis muscle in two patients with complete third nerve palsies to limit intermittent upper lid retraction after a frontalis sling procedure. This form of lid retraction is noted during periods of active facial movement with occipitofrontalis muscle contraction. Although upper lid position may be symmetric when the facial muscles are adynamic, the upper lid may retract during periods of active facial expression. This type of lid retraction was corrected using Botulinum A toxin injections into the frontalis muscles, without affecting the lid position when the facial muscles are adynamic. Both improvement in appearance and intermittent exposure were noted in both cases. Additionally, a blunting of the transverse forehead creases occurred over a defined area after this injection, representing a clinical example of a denervation field produced by a point injection of botulinum toxin.

Changes of morphological, biological and antigenic properties of avian influenza A virus haemagglutinin H2 in the course of adaptation to new host. (1995)

The alterations of avian influenza A virus haemagglutinin (HA) H2 as a result of adaptation to mice were first investigated in this study. HA of mouse-adapted (MA) variant was somewhat different from that of the original strain in electrophoretical mobility, antigenic structure and in haemagglutination activity with mouse red blood cells.
Oxygen Atom Transfer to a Half-Sandwich Iridium Complex: Clean Oxidation Yielding a Molecular Product (2014)

The oxidation of [Ir(Cp*)(phpy)(NCAr(F))][B(Ar(F))4] (1; Cp* = η(5)-pentamethylcyclopentadienyl, phpy = 2-phenylene-κC(1')-pyridine-κN, NCAr(F) = 3,5-bis(trifluoromethyl)benzonitrile, B(Ar(F))4 = tetrakis[3,5-bis(trifluoromethyl)phenyl]borate) with the oxygen atom transfer (OAT) reagent 2-tert-butylsulfonyliodosobenzene (sPhIO) yielded a single, molecular product at -40 °C. New Ir(Cp*) complexes with bidentate ligands derived by oxidation of phpy were synthesized to model possible products resulting from oxygen atom insertion into the iridium-carbon and/or iridium-nitrogen bonds of phpy. These new ligands were either cleaved from iridium by water or formed unreactive, phenoxide-bridged iridium dimers. The reactivity of these molecules suggested possible decomposition pathways of Ir(Cp*)-based water oxidation catalysts with bidentate ligands that are susceptible to oxidation. Monitoring the [Ir(Cp*)(phpy)(NCAr(F))](+) oxidation reaction by low-temperature NMR techniques revealed that the reaction involved two separate OAT events. An intermediate was detected, synthesized independently with trapping ligands, and characterized. The first oxidation step involves direct attack of the sPhIO oxidant on the carbon of the coordinated nitrile ligand. Oxygen atom transfer to carbon, followed by insertion into the iridium-carbon bond of phpy, formed a coordinated organic amide. A second oxygen atom transfer generated an unidentified iridium species (the "oxidized complex"). In the presence of triphenylphosphine, the "oxidized complex" proved capable of transferring one oxygen atom to phosphine, generating phosphine oxide and forming an Ir-PPh3 adduct in 92% yield. The final Ir-PPh3 product was fully characterized.
Bifunctional Ruthenium(II) Hydride Complexes with Pendant Strong Lewis Acid Moieties: Structure, Dynamics, and Cooperativity (2013)

The synthesis of a novel class of bifunctional ruthenium hydride complexes incorporating Lewis acidic BR2 moieties is reported. Determination of the molecular structures in the solid state and in solution provided evidence for tunable interaction between the two functionalities. Cooperative effects on the reactivity of the complexes were demonstrated including the activation of small Lewis basic molecules by reversible anchoring at the boron center.
Development of high-efficient compact Organic Rankine Cycle power generation technology utilizing waste heat (2017)

As the effective utilization method of unused heat energy between 100 and 300 degree-C in the industrial sector, Organic Rankine Cycle (ORC) was selected from the viewpoint of high efficiency. The prototype of air-cooled compact ORC electric power generation system for 1kW class was evaluated in variation of the ambient temperature of condenser and the suction temperature of expander. In the experimental results, at the expander suction temperature of 175°C and the ambient temperature of 20°C for condenser, the generated power by the expander is 1,027W and the gross power generation efficiency is 10.3%. The net power generation efficiency, considering the input power of auxiliary equipment such as pumps and fans, is 9.0%. In the result of energy balance analysis, power consumptions of the pump and the fan are small and almost of the generated power is effectively available.

Machine-learning of piezoelectric coefficients for wurtzite crystals (2023)

A handful of piezoelectrics cover all of today’s technologies, so there is a need to expand the range of accessible piezoelectric properties to enable future fundamental and technological advances. Focusing on Space Group 186, we have computed the piezoelectric properties of 47 materials, and deployed machine-learning models to reveal the quantities that control them. We have found reasonable linear models for the case of wurtzites, from a dataset of only 19 entries. Some of these models are based on easily retrievable features, while others involve features requiring additional computations. In the case of non-wurtzite materials, the statistical learning has not found any meaningful correlations, since the diversity of structures and compositions in a set of 26 non-wurtzite entries obliterates the influence of features on piezoelectric coefficients. The linear models presented for the wurtzite coefficients can potentially be used to inform future searches for wurtzite-structured alloys with higher piezoelectric coefficients.
Cooperative Spectrum Sharing Protocol with Secondary User Selection (2010)

In this paper, we propose a two-phase protocol based on cooperative relaying for a secondary system to achieve spectrum access along with a primary system. The primary system comprises of a transmitter-receiver pair PT-PR, and the secondary system comprises of M transmitters ST <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">i</sub> , i ∈ {1, 2,..., M} and a common receiver SR. The secondary transmitter ST <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">p</sub> which achieves the request target rate for the primary system is selected to serve as a decode-and-forward (DF) relay for the primary system. With the cooperation of ST <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">p</sub> , the primary system is able to tolerate interference lower than a certain threshold in the relaying phase, without degrading its outage performance. The secondary transmitter ST <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">s</sub> , which satisfies this interference constraint and provides the optimal outage performance for the secondary system, is then selected to access the spectrum band simultaneously when ST <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">p</sub> is relaying the primary signal. Theoretical and simulation results confirm the efficiency of the proposed spectrum sharing protocol, and we show that both primary and secondary systems are able to achieve better outage performance with increasing M.
Rewriting Interpolants (2008)

We give a method of constructing an interpolant for linear equality, and inequality constraints over the rational numbers. Our method is based on efficient rewriting techniques, and does not require the use of combination methods. The interpolant is constructed in such a way that it reflects the structure of the rewrite proof.
Highly efficient broad‐area blue and white light‐emitting diodes on bulk GaN substrates (2008)

Abstract Highly efficient light emitting diodes (LEDs) with peak emission wavelengths of nominally 450 nm were grown, fabricated and tested. The growth was performed by metal organic chemical vapour deposition. The LEDs were grown on c ‐plane (0001) bulk GaN substrates and fabricated into broad‐area devices with active area 0.01 cm 2 . Considerations were made to improve extraction efficiency, including transparent contacts, suspended mirror‐less packaging and encapsulation in a truncated pyramid optic. These factors resulted in LEDs with high peak external quantum efficiency and reduced efficiency droop. The output power and external quantum efficiency at 20 mA were 38.5 mW and 68.9%. At 100 mA, they were 170 mW and 60.9%. White LEDs were fabricated by application of a yellow phosphor to the blue LEDs. The white LED luminous flux and efficacy at 20 mA was 9.6 lm and 128 lm/W. The chromaticity coordinates and correlated colour temperature were (0.348 K, 0.378 K) and 4998 K. (© 2009 WILEY‐VCH Verlag GmbH &amp; Co. KGaA, Weinheim)
High-Temperature Drying of Thick Concrete Slabs (1976)

The foremost requirement for deep polymer impregnation of thick concrete slabs is thorough drying to remove all evaporable water from the pore system in concrete. To facilitate rapid repair of bridge decks with polymer impregnation, it is desirable to dry the concrete from the surface with surface temperatures not exceedings 700-800°F (370-420°C). A time-temperature-moisture loss study is presented on six 24x24x6-in.(610x610x150-mm) concrete slabs, a 72x72x8-in.(1800x1800x200-mm) slab and a small section of 7-1/2-in. (190-mm) bridge deck. The specimens were dried from one surface using an automated propane gas fired torch assembly. The feasibility of high-temperature drying of concrete without cracking problems is demonstrated and a criterion for safe and rapid drying to the depth of 4-6-in.(100-150-mm) in the field is developed.
Evaluating the Stability of Deep Image Quality Assessment with Respect to Image Scaling (2022)

Image quality assessment (IQA) is a fundamental metric for image processing tasks (e.g., compression). With full-reference IQAs, traditional IQAs, such as PSNR and SSIM, have been used. Recently, IQAs based on deep neural networks (deep IQAs), such as LPIPS and DISTS, have also been used. It is known that image scaling is inconsistent among deep IQAs, as some perform down-scaling as pre-processing, whereas others instead use the original image size. In this paper, we show that the image scale is an influential factor that affects deep IQA performance. We comprehensively evaluate four deep IQAs on the same five datasets, and the experimental results show that image scale significantly influences IQA performance. We found that the most appropriate image scale is often neither the default nor the original size, and the choice differs depending on the methods and datasets used. We visualized the stability and found that PieAPP is the most stable among the four deep IQAs.
The puzzle of zmpB and extensive chain formation, autolysis defect and non‐translocation of choline‐binding proteins in Streptococcus pneumoniae (2001)

Choline-binding proteins (CBPs) from Streptococcus pneumoniae are involved in several important processes. Inactivation of zmpB, a gene that encodes a surface-located putative zinc metalloprotease, in a S. pneumoniae serotype 4 strain was recently reported to reveal a composite phenotype, including extensive chain formation, lysis defect and transformation deficiency. This phenotype was associated with the lack of surface expression of several CBPs, including the major autolysin LytA. LytA, normally 36 kDa in size, was reported to form an SDS-resistant 80 kDa complex with CinA. ZmpB was therefore proposed to control translocation of CBPs to the surface, possibly through the proteolytic release of CBPs (and RecA) from CinA. Based on the use of 12 independent mariner insertions in the zmpB gene of the well-characterized R6 laboratory strain, we could not confirm several of these observations. Our zmpB mutants: (i) did not form chains; (ii) lysed normally in the presence of deoxycholate, which indicates the presence of a functional autolysin; (iii) transformed at normal frequency; and (iv) contained bona fide CinA and LytA species. Polymorphism of ZmpB between R6 and the serotype 4 isolate could not account for the discrepancy, as inactivation of zmpB (through replacement by transposon-inactivated zmpB R6 alleles) in the latter strain did not affect separation of daughter cells and autolysis. The conflicting observations could be explained by our finding that the reportedly serotype 4 zmpB 'mutant' differed from its S. pneumoniae parent in lacking capsule and in exhibiting characteristic traits of the Streptococcus viridans group, including resistance to optochin.
Arcuate Cluster Analysis in Glaucoma Perimetry (1993)

Typical glaucomatous visual field defects are often contiguous areas of diminished differential light sensitivity presenting as clusters of abnormally depressed points in the visual field chart. We investigated the value of recognizing arcuate cluster patterns, corresponding to the anatomy of the normal retinal nerve fiber layer. Cluster sizes were quantified using cluster volume and surface area. Clusters were analyzed separately in different regions of the visual field. Central 30 degrees static threshold fields from 87 eyes of 87 normal subjects and 101 eyes of 101 patients with glaucoma were studied. The two groups were discriminated with logistic regression. Central and nasal clusters were more indicative of glaucoma than were equally large clusters in other areas. Discrimination of normal and glaucoma eyes was significantly better with arcuate cluster analysis than with a traditional cluster analysis, which did not take cluster shape into account. Thus, arcuate cluster analysis was more sensitive to early central, paracentral, or nasal glaucomatous field loss and at the same time capable of deemphasizing common test artifacts and nondiagnostic field disturbances. Arcuate cluster volume gave better classification than did arcuate surface area. The results indicate that analysis of arcuate clusters offers substantial advantages as compared with traditional cluster analysis for recognition of early glaucomatous visual field loss.
