A recursive model for Rheotens tests (1997)

An iterative model is described to predict isothermal and nonisothermal elongation of an extruded filament at a given force. The principle of the model allows a quite simple description of Rheotens tests with much flexibility regarding the shape of the elongational viscosity function, including true viscoelastic flow and thermal boundary conditions. The algorithm is compact and computing time on a PC is short. The application of an integral K-BKZ constitutive equation to predict Rheotens curves of the well characterized LDPE Melt I is demonstrated and the influence of the slope of the transient viscosity in the strain-hardening regime is discussed. A simple approximation to take into account the prehistory of the material in the die based on purely elongational strains is proposed which includes the irreversibility assumption of the damping function (Wagner model). Predicted Rheotens curves are compared with experimental results.
DEVELOPMENT OF A HOUSE DUST MITE EVALUATION SYSTEM THROUGH IMAGE ANALYSIS AND ITS APPLICATION (2001)

Today in Japan, with the homes built more air-tight and thermally insulated, they lack sufficient ventilation, causing higher humidity and increased condensation indoors. This type of environment fosters proliferation of mites, growth of fungi, and accumulation of house dust - all allergens - causing residents living in such homes to suffer from allergy. This report discusses a newly developed system that allows engineering evaluation of the activity of mites in order to maintain comfort in the human living space of homes and control mites, or the major indoor allergen in Japanese homes. Using an image processing technology,the system directly observes mites with its built-in camera and analyzes the observed behavior of those tiny mites and evaluates through a computer-based image processing, thereby providing engineering analysis of the influence of mites on chemicals, building materials, utilities, indoor environment, and building structure. This mite image processing system is designed to obtain a correlation between the analysis results obtained from the image data of mites and their activity and perform quantitative evaluation of the activity. It provides quick evaluation related to mites in the home environment, such as effect of mite-killing or -repelling chemicals, effect of different levels of temperature and/or humidity on mites, and the biology of mites in the home environment.
Effect of atomic-state coherence and spontaneous emission on three-level dynamics (1990)

For a three-level atom in the ssV configuration (i.e., having two excited states each dipole-coupled to a common ground state), we have found a particular linear combination of bare-atom states in which Rabi oscillations and their associated collapses and revivals do not occur. Moving to a dressed-state picture, we discover that this particular linear combination state is just that dressed state which is decoupled from all the field modes. It is a dressed state for which the transition dipole moments with the other dressed states are zero. The existence of this decoupled dressed state depends on the tuning of the dressing laser field, which in turn depends on the bare-atom excited-state dipole moments and energy-level separation. When we include spontaneous emission, the population decays from the other dressed states into this decoupled state and remains coherently trapped there, producing a system that experiences no dynamical behavior. This is exact for \ensuremath{\delta}-function photon statistics (i.e., if there is no intensity uncertainty). The trapping becomes less perfect as the photon statistics are allowed to have a greater bandwidth. Also, if the applied field is tuned incorrectly, the spontaneous realignment of the atomic state amplitudes does not result in a totally decoupled dressed state, and the dynamics proceed normally.
Fabrication artifacts and parallel loss channels in metamorphic epitaxial aluminum superconducting resonators (2016)

Fabrication of coplanar waveguide resonators with internal quality factors near 10<sup>6</sup> remains challenging. In this work, high-purity single crystal superconductors are implemented through metamorphic epitaxial aluminum that is grown via molecular beam epitaxy on silicon and sapphire substrates. X- ray diffraction and scanning transmission electron microscopy indicate an abrupt highly ordered interface that results in crystal relaxation within a few monolayers of the substrate interface and no measurable interfacial contamination. Quarter- wave coplanar waveguide resonators are fabricated using optical lithography and measured at temperatures below 100 mK. Post measurement characterization with charge contrast imaging in a scanning electron microscope identifies processing artifacts at the waveguide sidewalls, on the exposed substrate area and on the exposed aluminum surface. Of primary importance are processing induced corrosion defects on aluminum sidewalls, nanoparticle contamination, and photoresist residue that are difficult to remove without affecting the superconductor material. Likely correlations between these artifacts and the measured quality factor are discussed in context of device to device variations in resonator performance.
Pose Estimation of Vehicles Over Uneven Terrain (2019)

This paper presents a method for pose estimation of off-road vehicles moving over uneven terrain. It determines the contact points between the wheels and the terrain, assuming rigid contacts between an arbitrary number of wheels and ground. The terrain is represented by a 3D points cloud, interpolated by a B-patch to provide a continuous terrain representation. The pose estimation problem is formulated as a rigid body contact problem for a given location of the vehicle's center of mass over the terrain and a given yaw angle. The contact points between the wheels and ground are determined by releasing the vehicle from a given point above the terrain, until the contact forces between the wheels and ground, and the gravitational force, reach equilibrium. The contact forces are calculated using singular value decomposition (SVD) of the deduced contact matrix. The proposed method is computationally efficient, allowing real time computation during motion, as demonstrated in several examples. Accurate pose estimations can be used for motion planning, stability analyses and traversability analyses over uneven terrain.
Selenium-containing histone deacetylase inhibitors for melanoma management (2012)

Melanoma incidence and mortality rates continue to increase each year. Lack of clinically viable agents, drug combinations, effective targeted delivery approaches and success inhibiting targets in tumor tissue have made this disease one of the most difficult to treat, which makes prevention an important option for decreasing disease incidence and mortality rates. Inhibiting histone deacetylases (HDAC) is an approach currently being explored to more effectively treat melanoma but use for prevention has not been explored. In this study, novel selenium containing derivatives of the FDA approved HDAC inhibitor suberoylanilide hydroxamic acid (SAHA) called 5-phenylcarbamoylpentyl selenocyanide (PCP-SeCN) and Bis{5-phenylcarbamoylpentyl} diselenide (B(PCP)-2Se) were created and efficacy tested for preventing early melanocytic lesion development in skin. Topical application of PCP-SeCN and B(PCP)-2Se inhibited melanocytic lesion development in laboratory-generated skin by up to 87% with negligible toxicological effect. Mechanistically, PCP-SeCN and B(PCP)-2Se inhibited HDAC activity and had new inhibitory properties by moderating Akt activity to induce cellular apoptosis as demonstrated by an increase in the sub-G₀-G₁ cell population, and cleaved caspase-3 as well as PARP levels. Furthermore, PCP-SeCN and B(PCP)-2Se inhibited cell proliferation by inhibiting cyclin D1 expression and increasing p21 levels. Thus, PCP-SeCN and B(PCP)-2Se are potential melanoma chemopreventive agents with enhanced efficacy compared with SAHA due to new PI3 kinase pathway inhibitory properties.

Evidence of the Presence of a Specific ATPase Responsible for ATP-initiated Calcification by Matrix Vesicles Isolated from Cartilage and Bone (1996)

Accumulating evidence indicates that calcification by isolated mammalian matrix vesicles (MVs) can be initiated by ATP. Since ATP can be hydrolyzed by either a specific ATPase or by nonspecific alkaline phosphatase (ALP), it remains to be established whether ATPase or ALP mediates ATP-initiated Ca and Pi deposition. To support the hypothesis that specific ATPase is responsible for ATP-initiated calcification by MVs isolated from mammalian cartilage and bone, the effects of ATP analogs, ALP substrates, and specific inhibitors on ATP hydrolysis and ATP-initiated calcification were compared between intact MVs and monoclonal antibody affinity-purified MV ALP. ATP analogs such as ADP and AMP exerted marked inhibitory effects on both [gamma-32P]ATP hydrolysis and ATP-initiated calcification by intact MVs, whereas phosphomonoesters such as beta-glycerophosphate or phosphoethanolamine had no effect. In contrast to intact MVs, purified MV ALP failed to calcify, and its [gamma-32P]ATP hydrolytic activity was readily inhibited by phosphomonoesters. Additionally, [gamma-32P]ATP hydrolysis by purified ALP in contrast to that by intact vesicles was completely inhibited by l-tetramisole, a specific inhibitor of ALP, suggesting a loss of specific ATPase during purification. Vanadate inhibition of ATP hydrolysis by purified ALP can be decreased by increasing ATP concentrations. On the contrary, ATP concentrations did not affect vanadate inhibition of ATP hydrolysis by intact MVs if ALP activity was blocked by l-tetramisole. These observations, therefore, suggest that: 1) a portion of [gamma-32P]ATP hydrolysis by MVs is attributable to a specific ATPase, whereas the remaining activity is due to ALP; and 2) a specific ATPase, but not ALP, is responsible for ATP-dependent Ca- and Pi-depositing activity of MVs isolated from bone or cartilage.
Wavefront distortion optimized with volume Bragg gratings in photothermorefractive glass (2016)

The wavefront characteristics in 2D angular filtering on the basis of two orthogonal transmitting volume Bragg gratings (VBGs) is presented. The experimental results show that middle-high frequency wavefront distortions are efficiently suppressed with VBGs. The peak-valley value of the beam at a wavelength of 1053 nm reduces from 2.075λ to 0.209λ, and the root mean square value reduces from 0.207λ to 0.041λ. The wavefront power spectrum density shows that the wavefront distribution of the beam in medium and high frequencies is corrected by the VBGs. Additionally, the far-field distribution and focusing properties of the beam are improved. The beam Strehl ratio increases from 0.43 to 0.96, and the encircled energy improves from 95% energy at 4.01 mrad to 95% energy at 1.26 mrad.
<i>Xenopus Zic</i> 3, a primary regulator both in neural and neural crest development (1997)

Xenopus Zic3 is a Xenopus homologue of mouse Zic and Drosophila pair-rule gene, odd-paired. We show here that Zic3 has significant roles both in neural and neural crest development in Xenopus embryo. Expression of Zic3 is first detected in prospective neural plate region at gastrulation. Onset of the expression was earlier than most proneural genes and followed chordin expression. The expression was induced by blockade of BMP4 signal. Overexpression of Zic3 resulted in hyperplastic neural and neural crest derived tissue. In animal cap explant, the overexpression of Zic3 induced expression of all the proneural genes and neural crest marker genes. These findings suggest that Zic3 can determine the ectodermal cell fate and promote the earliest step of neural and neural crest development.
Characteristics of Traveling Wave Helices in ESR Spectrometers (1967)

Design criteria for construction of helices for microwave spectrometers are discussed with particular attention to large magnetic fields required for double resonance work. Some coil-to-guide matching techniques are evaluated with regard to efficiency, sensitivity, and simplicity. Techniques of coil and match evaluation are discussed in detail.
Protocol selection and interface generation for HW-SW codesign (1997)

The aim of this paper is to present a communication synthesis approach stated as an allocation problem. In the proposed approach, communication synthesis allows to transform a system composed of processes that communicate via high-level primitives through abstract channels into a set of processes executed by interconnected processors that communicate via signals and share communication control. The proposed communication synthesis approach deals with both protocol selection and interface generation and is based on binding/allocation of communication units. This approach allows a wide design space exploration through automatic selection of communication protocols. We present a new algorithm that performs binding/allocation of communication units. This algorithm makes use of a cost function to evaluate different allocation alternatives. We illustrate through an example the usefulness of the algorithm for allocating automatically different protocols within the same application system.
A comprehensive/selective mm-wave satellite downlink experiment on fade dynamics (1997)

The paper gives a succinct but comprehensive overview of an experimental set-up, salient features and initial results of a satellite downlink propagation experiment at 40 GHz and referred to propagation and communication-related results. The global objective of the research aims at a better understanding of dynamic fading and C/N/sub 0/ ratios, whether due to cloud attenuation and its variability, or to rain plus tropospheric (clear air) scintillations and sky temperature fluctuations.
A Dataset and a Technique for Generalized Nuclear Segmentation for Computational Pathology (2017)

Nuclear segmentation in digital microscopic tissue images can enable extraction of high-quality features for nuclear morphometrics and other analysis in computational pathology. Conventional image processing techniques, such as Otsu thresholding and watershed segmentation, do not work effectively on challenging cases, such as chromatin-sparse and crowded nuclei. In contrast, machine learning-based segmentation can generalize across various nuclear appearances. However, training machine learning algorithms requires data sets of images, in which a vast number of nuclei have been annotated. Publicly accessible and annotated data sets, along with widely agreed upon metrics to compare techniques, have catalyzed tremendous innovation and progress on other image classification problems, particularly in object recognition. Inspired by their success, we introduce a large publicly accessible data set of hematoxylin and eosin (H&E)-stained tissue images with more than 21000 painstakingly annotated nuclear boundaries, whose quality was validated by a medical doctor. Because our data set is taken from multiple hospitals and includes a diversity of nuclear appearances from several patients, disease states, and organs, techniques trained on it are likely to generalize well and work right out-of-the-box on other H&E-stained images. We also propose a new metric to evaluate nuclear segmentation results that penalizes object- and pixel-level errors in a unified manner, unlike previous metrics that penalize only one type of error. We also propose a segmentation technique based on deep learning that lays a special emphasis on identifying the nuclear boundaries, including those between the touching or overlapping nuclei, and works well on a diverse set of test images.
Regions of active damping control for LCL filters (2012)

The control of a grid connected voltage source inverter (VSI) with an LCL filter is a very challenging task, since the LCL network causes a resonance phenomenon near to the control stability boundary. While many active damping methods have been proposed to overcome this issue, the role that PWM transport delay plays in the effectiveness of these strategies is still not fully resolved. This paper presents a theoretical discrete time analysis frame work that identifies three distinct regions of LCL filter resonance - a high resonant frequency region where active damping isn't required; a critical resonant frequency where a controller cannot stabilise the system; and a low resonant frequency region where active damping is essential. Suitable controllers are then proposed for the two stable regions, with gain calculations that allow for the greatest system bandwidth and damping. Simulation and experimental results verify the presented analysis.
Weak Keys of the Full MISTY1 Block Cipher for Related-Key Cryptanalysis. (2012)

The MISTY1 block cipher has a 64-bit block length, a 128-bit user key and a recommended number of 8 rounds. It is a Japanese CRYPTREC-recommended e-government cipher, an European NESSIE selected cipher, and an ISO international standard. Despite of considerable cryptanalytic efforts during the past fifteen years, there has been no published cryptanalytic attack on the full MISTY1 cipher algorithm. In this paper, we present related-key differential and related-key amplified boomerang attacks on the full MISTY1 under certain weak key assumptions: We describe 2 103.57 weak keys and a related-key differential attack on the full MISTY1 with a data complexity of 2 61 chosen ciphertexts and a time complexity of 2 87.94 encryptions; and we also describe 2 92 weak keys and a related-key amplified boomerang attack on the full MISTY1 with a data complexity of 2 60.5 chosen plaintexts and a time complexity of 2 80.18 encryptions. For the very first time, our results exhibit a cryptographic weakness in the full MISTY1 cipher (when used with the recommended 8 rounds), and show that the MISTY1 cipher is distinguishable from a random function and thus cannot be regarded to be an ideal cipher.
ARCD-1, an apobec-1-related cytidine deaminase, exerts a dominant negative effect on C to U RNA editing (2001)

Mammalian apolipoprotein B (apoB) C to U RNA editing is catalyzed by a multicomponent holoenzyme containing a single catalytic subunit, apobec-1. We have characterized an apobec-1 homologue, ARCD-1, located on chromosome 6p21.1, and determined its role in apoB mRNA editing. ARCD-1 mRNA is ubiquitously expressed; phylogenetic analysis reveals it to be a distant member of the RNA editing family. Recombinant ARCD-1 demonstrates cytidine deaminase and apoB RNA binding activity but does not catalyze C to U RNA editing, either in vitro or in vivo. Although not competent itself to mediate deamination of apoB mRNA, ARCD-1 inhibits apobec-1-mediated C to U RNA editing. ARCD-1 interacts and heterodimerizes with both apobec-1 and apobec-1 complementation factor (ACF) and localizes to both the nucleus and cytoplasm of transfected cells. Together, the data suggest that ARCD-1 is a novel cytidine deaminase that interacts with apobec-1 and ACF to inhibit apoB mRNA editing, possibly through interaction with other protein components of the apoB RNA editing holoenzyme.
Regulation of glycoprotein IIb-IIIa receptor function studied with platelets permeabilized by the pore-forming complement proteins C5b-9. (1992)

Recent evidence suggests that the cytoplasmic domains of platelet glycoprotein (GP) IIb-IIIa are involved in the agonist-initiated transformation of this integrin into a receptor for fibrinogen. To identify intracellular reactions that regulate the receptor function of GP IIb-IIIa, membrane-impermeable agonists and antagonists were introduced into the platelet by permeabilizing the plasma membrane with the pore-forming complement proteins C5b-9. Platelet responses were then analyzed by flow cytometry. Non-lytic concentrations of C5b-9 caused permeabilization of the platelet plasma membrane, as determined by uptake of a water-soluble fluorescent tracer dye. The complement pores were large enough to permit the entry of fluorescein isothiocyanate (FITC)-labeled oligopeptides in a size-dependent manner. Under conditions of low external Ca2+, C5b-9 treatment per se did not activate GP IIb-IIIa, as measured by binding of the activation-dependent antibody FITC-PAC1. However, FITC-PAC1 binding to C5b-9-permeabilized platelets was stimulated by a thrombin receptor agonist acting at the cell surface and by guanosine 5'-O-(thiotriphosphate), a membrane-impermeable activator of G proteins. Permeabilization also permitted the entry of cyclic AMP and the peptide, RFARKGALRQKNV, a pseudo-substrate inhibitor of protein kinase C. Each of these inhibited agonist-induced FITC-PAC1 binding to permeabilized platelets but not to intact platelets. Agonist-induced GP IIb-IIIa activation in permeabilized platelets was also inhibited by tyrphostin-23, a protein tyrosine kinase inhibitor. Thus, C5b-9 can be used to permeabilize the plasma membrane to permit the selective entry of small peptides and other bioactive compounds into permeabilized platelets. Results obtained with these platelets indicate that GP IIb-IIIa receptor function is regulated by a network of signaling reactions involving G proteins, serine/threonine kinases, and tyrosine kinases.
Automatic image‐driven segmentation of the ventricles in cardiac cine MRI (2008)

The proposed method is feasible, fast, and robust against anatomical variability and image contrast variations.
CO<sub>2</sub> Separation from Flue Gas Using Polyvinyl-(Room Temperature Ionic Liquid)–Room Temperature Ionic Liquid Composite Membranes (2011)

In this work, a vinyl-functionalized room temperature ionic liquid (RTIL), 1-vinyl-3-butylimidazolium bis(trifluoromethylsulfonyl)imide ([vbim][Tf2N]), has been successfully synthesized. The RTIL was further polymerized and mixed with 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([bmim][Tf2N]) to form the free-standing poly([vbim][Tf2N])–[bmim][Tf2N] composite films. The compositions of [bmim][Tf2N] in the composite membranes were designed at 15, 30, 45, and 60 wt %. The pristine poly([vbim][Tf2N]) and poly([vbim][Tf2N])–[bmim][Tf2N] composite membranes exhibit similar permeability selectivities as the standard [bmim][Tf2N] but permeabilities are enhanced up to 5 times higher than the equivalent polystyrene-RTIL and polyacrylate-RTIL membranes. An increase in [bmim][Tf2N] concentration of poly([vbim][Tf2N])–[bmim][Tf2N] composite membranes results in an increase in solubility, diffusivity, and permeability coefficients of CO2 and N2 but does not change the CO2/N2 selectivities of the solubility, diffusivity, and permeability. The CO2 permeability of the 60 wt % composite at 35 °C, 10 atm is 559 barrers in pure gas tests which is closer to 60% of the [bmim][Tf2N] permeability (i.e., 1344 barrers). In addition, the 60 wt % composite membrane exhibits a CO2 permeability of 491.2 barrers and a CO2/N2 selectivity of 20 in mixed gas tests using CO2/N2 (50:50) as the feed.
