Synchrotron radiation lithography system in an atmospheric environment (invited) (1989)

The atmospheric environmental exposure system for synchrotron radiation (SR) lithography has been integrated using the Photon Factory storage ring (2.5 GeV). The system, composed of a highly reliable beamline, an SR extracting chamber and a prototype SR stepper, aims at attaining higher accuracy and throughput. Based on a fail-safe mechanism notion, a double-vacuum protection system, in which two sets of a fast closing valve and acoustic delay line are installed in the main beamline and branch beamline, respectively, has been organized. Vacuum breakdown tests indicated that any vacuum breakdown, a beryllium (Be) window rupture in the worst case, exerts little influence on the storage ring ultrahigh vacuum. The SR extracting chamber, equipped with a Be window and an extraction window, is filled with helium at atmospheric pressure. Particularly, the 50-μm-thick, 35-mm-diam Be window, vacuum-sealed by a Viton O-ring, was preliminarily employed and, so far, has operated successfully, giving a 25-mm square exposure area. In terms of practical availability and simplicity, the SR stepper in an atmospheric environment has been constructed. A novel differential mode linear Fresnel zone plate alignment method, which can detect an alignment error between a mask and a wafer during exposure, was developed.
Topological phase transitions of Thouless charge pumping realized in helical organic molecules with long-range hopping (2020)

Recent studies indicated that helical organic molecules, such as DNA and the $\ensuremath{\alpha}$-helical protein, can behave as Thouless quantum pumps when a rotating electric field is applied perpendicularly to their helical axes. Here we investigate the influence of long-range hoppings on this topological pumping of electrons in single-helical organic molecules. Under variation of the long-range hoppings governed by a decay exponent $\ensuremath{\mu}$, we find an energy gap in the molecular band structure closes at a critical value ${\ensuremath{\mu}}_{c}$ of the decay exponent and reopens for $\ensuremath{\mu}$ deviating from ${\ensuremath{\mu}}_{c}$. The relevant bulk bands in a pumping cycle acquire different Chern numbers in the strong ($\ensuremath{\mu}&lt;{\ensuremath{\mu}}_{c}$) and weak ($\ensuremath{\mu}&gt;{\ensuremath{\mu}}_{c}$) long-range hopping regimes, with a sudden jump at criticality. This topological phase transition is also shown to separate two distinct behaviors of the midgap end states in the pumping process. The end states carry quantized current pumped by the rotating electric field, and the current forms a plateau by sweeping the Fermi energy over the gap. In the strong-hopping phase, the quantized current plateau is positive, which is reversed to a negative one with smaller amplitude in the weak-hopping phase. However, the reversal is a smooth crossover, not a sharp transition, due to the finite sizes of the molecules. We show that these transport characteristics of the topological phase transition could also be observed at finite temperatures.
Morphology and physiologic responsiveness of cultured rabbit lacrimal acini. (1994)

Under the conditions described, cultures of intact lacrimal acini from New Zealand white rabbits maintain histotypic morphology and physiologic responsiveness similar to fresh lacrimal gland and incubated tissue slices. Culture of the acini affords a useful alternative for the study of chronic, as well as acute, effects of neurotransmitters, neuropeptides, hormones, and cytokines on the structure and function of the gland.
Using Complex Event Processing for Dynamic Business Process Adaptation (2010)

As the amount of data generated by today's pervasive environments increases exponentially, there is a stronger need to decipher the important information that is hidden among it. By using complex event processing, we can obtain the information that really matters to our organization and use it to improve our processes. However, even when this information is retrieved, business processes remain static and cannot be changed dynamically to adapt to the actual scenario, diminishing the advantages that can be achieved. In this paper we present CEVICHE, a framework that combines the strengths of complex event processing and dynamic business process adaptation, which allows to respond to the needs of today's rapidly changing environments. We use a simple car rental scenario to show how CEVICHE could be used to maintain the quality of service of a business process by adapting it according to the situation.
Superconducting properties of an Ag-CLAD (BiPb)_2Sr_2Ca_2Cu_3O_10+y tape (1993)

AC susceptibility and V-I characteristics of a well characterised Ag-clad Bi-Pb-Sr-Ca-Cu-O tape have been studied in the temperature (T) range 77-106 K and magnetic fields (B) up to 0.06 T. The intrinsic critical current density J_s (from ac susceptibility) is 30000 A/cm2 at 77 K whereas the transport critical current density Jc (from V-I curves) is 10100 A/cm2 at the same temperature. Both Js and Jc showed power law variations with T and B, respectively, characteristic for intragranular flux creep. From the dissipation within the core the differential resistance Rf (associated with the flux flow) has been deduced. The magnitude and the variations of Rf with T and B are consistent with those due to flux flow in type II superconductors in low field. From d^2 V/d I^2 vs I curves very broad critical current distribution CCD has been deduced.
H1 histamine receptors accelerate the regrowth of the biliary tree after 70% hepatectomy (2011)

Histamine interacts with four types of receptors, HRH1–4. Activation of HRH1 stimulates, whereas HRH3/4 decrease biliary growth. VEGF-A/C are autocrine/paracrine factors regulating biliary function. We propose that HRH1 and HRH3 agonists induce differential effects on biliary regeneration after partial hepatectomy (PH) via changes in biliary VEGF expression. After PH, rats were treated with HRH1 (HTMT) or HRH3 agonists (RAMH) at 1–12 hr and up to 7 days. We studied in liver sections: (i) PCNA- and VEGF-A/C-positive cholangiocytes; and (ii) bile duct mass (IBDM) and biliary apoptosis. Normal rat cholangiocytes (NRIC) were stimulated with HTMT or RAMH (10 μM) for 6 hr. In NRIC we evaluated angiogenic markers by microarray and VEGF gene expression. NRIC supernatants were co-cultured with vascular endothelial cells. PCNA-positive cholangiocytes and IBDM (low in controls) increased (peak day 3) in HTMT-treated rats. In RAMH-treated rats, biliary mitosis and IBDM decreased at day 3. Apoptosis decreased in HTMT- and increased in RAMH-treated rats. VEGF expression increased in HTMT-treated rats. We show upregulation of numerous angiogenic factors including VEGF-A/C after stimulation with HTMT. Endothelial tube formation increased in HTMT-treated NRIC supernatants. Changes in VEGF expression by HRH1 agonists is important in post-liver transplantation.
Spiking Optical Flow for Event-based Sensors Using IBM's TrueNorth\n Neurosynaptic System (2017)

This paper describes a fully spike-based neural network for optical flow\nestimation from Dynamic Vision Sensor data. A low power embedded implementation\nof the method which combines the Asynchronous Time-based Image Sensor with\nIBM's TrueNorth Neurosynaptic System is presented. The sensor generates spikes\nwith sub-millisecond resolution in response to scene illumination changes.\nThese spike are processed by a spiking neural network running on TrueNorth with\na 1 millisecond resolution to accurately determine the order and time\ndifference of spikes from neighboring pixels, and therefore infer the velocity.\nThe spiking neural network is a variant of the Barlow Levick method for optical\nflow estimation. The system is evaluated on two recordings for which ground\ntruth motion is available, and achieves an Average Endpoint Error of 11% at an\nestimated power budget of under 80mW for the sensor and computation.\n
An exploration of relationships among measures of social cognition, decision making, and emotional intelligence (2012)

The present study examined the relationships among measures that purportedly assess emotional intelligence (EI), social cognition, and emotional decision making within a sample of nonclinical undergraduate participants. Forty participants, both male and female, who scored in either the highest or the lowest quartiles of an EI measure (the Trait Meta-Mood Scale) completed the Reading the Mind in the Eyes Test and the Iowa Gambling Task. As expected, main effects for gender and EI level occurred, as women outperformed men on the Eyes Test, and participants in the higher EI group outperformed those in the lower EI group on the Eyes Test. Additionally, men classified in the higher EI group performed significantly better on the Eyes Test than men in the lower EI group. However, no group or gender differences were found on the Iowa Gambling Task.
Atomistic simulation of ionic and electronic defects in YBa2Cu3O7 (1988)

An empirical two-body potential model has been developed in order to describe the electronic and ionic defect properties of orthorhombic Y${\mathrm{Ba}}_{2}$${\mathrm{Cu}}_{3}$${\mathrm{O}}_{7}$. The potential model was derived starting from known potentials and calculated potentials and fits the crystal structure to better than 0.03 \AA{} for the major bonds. Oxygen vacancy formation and hole trapping as a localized polaron are most favorable at the chain oxygen ion site 1. Hole trapping on ${\mathrm{Cu}}^{2+}$ ions is most favorable for ions in the copper-oxygen plane. Divalent impurity ions such as ${\mathrm{Ni}}^{2+}$, ${\mathrm{Zn}}^{2+}$, and ${\mathrm{Cd}}^{2+}$ can dissolve in the crystal preferentially at the ${\mathrm{Cu}}^{2+}$ plane site 2. On the other hand, trivalent impurities such as ${\mathrm{Al}}^{3+}$, ${\mathrm{Fe}}^{3+}$, and ${\mathrm{Ga}}^{3+}$ dissolve in the crystal at the chain ${\mathrm{Cu}}^{2+}$ site 1 along with the incorporation of oxygen ions. Anions such as ${\mathrm{S}}^{2\ensuremath{-}}$, ${\mathrm{Cl}}^{\ensuremath{-}}$, or ${\mathrm{F}}^{\ensuremath{-}}$ would preferentially substitute for ${\mathrm{O}}^{2\ensuremath{-}}$ at sites near the ${\mathrm{Cu}}^{2+}$ chain position.
Wavelet Threshold-Based ECG Data Compression Technique Using Immune Optimization Algorithm (2015)

In this paper, a new ECG compression method called Wavelet Threshold Based Immune Algorithm (WTBIA) is proposed. This method based on finding the best threshold level for each wavelet subband using Immune Algorithm (IA). The WTBIA algorithm consists of three main steps: 1) Applying 1-D Discrete Wavelet Transform (DWT) on ECG signal; 2) Thresholding of wavelet coefficients in each subband; and 3) Minimization of the Percent Root mean square Difference (PRD) and maximization of the Compression Ratio (CR) using IA. The main advantage of this method is finding the best threshold level for each subband based on the required CR and PRD. The compression algorithm was implemented and tested upon records selected from the MIT-BIH arrhythmia database Simulation results show that the proposed algorithm leads to high CR associated with low distortion level relative to previously reported compression algorithms.
Anaplastic large cell lymphoma (Ki‐1+/CD30+) in childhood (1993)

In 1985, Stein et al. (Blood 66:848-858) described a large cell lymphoma consisting of activated lymphoid elements, expressing the Reed-Sternberg cell-associated antigen Ki-1 (CD30); this tumor has recently been included in the updated Kiel classification and has been termed anaplastic large cell lymphoma (ALCL). This report concerns 13 patients with previously untreated ALCL who were admitted to the Pediatric Hematology and Oncology Department of Bologna University between January 1983 and December 1989. Ten cases were diagnosed as common type ALCL, 1 as Hodgkin's-related ALCL and the remaining 2 as histiocyte-rich ALCL/lymphohistiocytic T-cell lymphoma. T-cell markers were present in 85% of the cases, and B phenotype in the remaining 15%. About one-half of the patients presented systemic symptoms; all but one showed more than one involved site, mostly an association of nodal and extranodal sites. All patients (1 in stage I, 7 in stage II, and 5 in stage III) were treated with a modified version of the LSA2-L2 protocol. Survival and event-free survival at 4 years were 100% and 62.9%, respectively. Two out of 3 relapsed patients presented a recurrence of disease when they were off-therapy 24 and 36 months after first complete remission. Good response to salvage chemotherapy of all the relapsed patients and the long duration of the second complete remission were a distinctive characteristic of this neoplasm when compared to other histological subtypes. The clinical presentation, the tendency to develop late relapses and to achieve and maintain second remission easily suggest that ALCL is a high grade non-Hodgkin's lymphoma, from the histological point of view, but is similar to Hodgkin's disease from the clinical point of view. This would confirm the hypothesis that Hodgkin's disease and ALCL represent a continuous spectrum of the same disease.
Detection of Visual Defects Using the Contrast Sensitivity Function (1980)

In this chapter the theoretical reasons were outlined and clinical data summarized as to why spatial contrast measurements can reveal visual losses that are not uncovered by testing visual acuity, no matter which optotype one uses or how carefully the measurement is made. Spatial contrast sensitivity measurements may disclose different types of contrast losses in patients with different lesions but with identical visual acuity. The relationship of different types of spatial contrast sensitivity losses (plotted as visuograms) to specific location or cause of lesions is not yet clear. Patients with glaucoma show losses that occur infrequently in other types of eye or visual pathway diseases, but the specificity of the typical contrast loss needs confirmation. The definite clinical value of contrast sensitivity measurements is that they can identify incipient abnormalities in the visual pathways that subserve foveal vision. In addition to this definite diagnostic application, using sinusoidal gratings as stimuli for both contrast sensitivity and for VEP measurements is useful in a research-oriented clinical testing facility.
A Simple Relationship for High Efficiency-Gradient Uniformity Trade-Offs in Multi-Layer Asymmetric Gradient Coils (2006)

H. Sanchez Lopez, F. Liu, A. Trakic, S. Crozier School of Information Technology and Electrical Engineering, University of Queensland, Brisbane, Queensland, Australia Introduction: This study details the design trade-offs available for asymmetric gradients and particularly investigates both scaling laws and appropriate relaxation factors useful in the design process. Recently a linear function interrelating coil diameter and DSV with the shortest length high performance symmetric gradient coils has been presented [1]. It is well-known that relaxing the magnetic field quality is one of the ways to obtain gradient coils with high figure of merit M=(ηρ1)/L. It is not clear, however, how this relaxation factor is related with DSV size, coil length and radius to produce maximal M. In this work, we have studied the influence of DSV, coil length and radius, relative axial offset position of DSV and target gradient field uniformity over the figure of merit in multi-layer asymmetric transverse gradient coils. A simple linear function that defines the optimal coil length to produce a maximum figure of merit given a DSV size, coil radius, axial offset position and introduced uniformity error is obtained.
Analysis of Univariate Nonstationary Subdivision Schemes with Application to Gaussian-Based Interpolatory Schemes (2007)

This paper is concerned with nonstationary subdivision schemes. First, we derive new sufficient conditions for $C^\nu$ smoothness of such schemes. Next, a new class of interpolatory $2m$-point nonstationary subdivision schemes based on Gaussian interpolation is presented. These schemes are shown to be $C^{L+\mu}$ with $L\in{\mathbb Z}_+$ and $\mu\in(0,1)$, where L is the integer smoothness order of the known $2m$-point Deslauriers–Dubuc interpolatory schemes.

A novel resonant converter topology and its application (2002)

This paper describes a secondary side resonant converter with particular suitability to step up and high power applications. A description of the basic circuit is followed by a detailed description and some important developments building upon the basic circuit, including inversion and bi-directional configurations. Efficiency is very good (/spl ap/94%) as a result of the zero voltage switching and zero current switching operation, and this is demonstrated with test data for two prototype configurations from 1 kW to 6 kW.

Dynamic range enhancement of nonlinear nanomechanical resonant cantilevers for highly sensitive NEMS gas/mass sensor applications (2010)

This paper describes a comprehensive nonlinear multiphysics model based on the Euler-Bernoulli equation that remains valid up to large displacements in the case of electrostatically actuated nanocantilevers. This purely analytical model takes into account the fringing field effects which are significant for thin resonators. Analytical simulations show very good agreement with experimental electrical measurements of silicon nanodevices using wafer-scale nanostencil lithography (nSL), monolithically integrated with CMOS circuits. Close-form expressions of the critical amplitude are provided in order to compare the dynamic ranges of NEMS cantilevers and doubly clamped beams. This model allows designers to cancel out nonlinearities by tuning some design parameters and thus gives the possibility of driving the cantilever beyond its critical amplitude. Consequently, the sensor performance can be enhanced by being optimally driven at very large amplitude, while maintaining linear behavior.
Wake Control by Boundary Layer Suction Applied to a High-Lift Low-Pressure Turbine Blade (2010)

Wake control by boundary layer suction has been applied to a high-lift low-pressure turbine blade with the intention of reducing the wake velocity defect, hence attenuating wake-blade interaction, and consequently the generation of tonal noise. The experimental investigation has been performed in a large scale linear turbine cascade at midspan. Two Reynolds number conditions (Re = 300000 and Re = 100000), representative of the typical operating conditions of the low pressure aeroengine turbines, have been analyzed. Boundary layer suction has been implemented through a slot placed in the rear part of the profile suction side. The suction rate has been varied in order to investigate its influence on the wake reduction. Mean velocity and Reynolds stress components in the blade to blade plane have been measured by means of a two-component crossed miniature hot-wire. The wake shed from the central blade has been investigated in several traverses in the direction normal to the camber line at the cascade exit. The traverses are located at distances ranging between 5 and 80% of the blade chord from the blade trailing edge. To get an overall estimate of the wake velocity defect reductions obtained by the application of boundary layer suction, the integral parameters of the wake have been also estimated. Moreover, spectra of the velocity fluctuations have been evaluated to get information on the unsteady behaviour of the wake flow when boundary layer suction is applied. The results obtained in the wake controlled by boundary layer suction have been compared with the results in the baseline profile wake at both Reynolds number conditions for the purpose of evaluating the control technique effectiveness. The removal of boundary layer through the slot in the rear part of the profile suction side has been proved to be very effective in reducing the wake shed from the profile. The results show that a reduction greater than 65% of the wake displacement and momentum thicknesses at Re = 300000, and a reduction greater than 75% at Re = 100000 can be achieved by removal of 1.5% and 1.8% of the single passage through flow, respectively.
Pharmacologic Inhibition of Cyclin-Dependent Kinases 4 and 6 Arrests the Growth of Glioblastoma Multiforme Intracranial Xenografts (2010)

Activation of cyclin-dependent kinases 4 and 6 (cdk4/6) occurs in the majority of glioblastoma multiforme (GBM) tumors, and represents a promising molecular target for the development of small molecule inhibitors. In the current study, we investigated the molecular determinants and in vivo response of diverse GBM cell lines and xenografts to PD-0332991, a cdk4/6-specific inhibitor. In vitro testing of PD-0332991 against a panel of GBM cell lines revealed a potent G(1) cell cycle arrest and induction of senescence in each of 16 retinoblastoma protein (Rb)-proficient cell lines regardless of other genetic lesions, whereas 5 cell lines with homozygous inactivation of Rb were completely resistant to treatment. Short hairpin RNA depletion of Rb expression conferred resistance of GBM cells to PD-0332991, further demonstrating a requirement of Rb for sensitivity to cdk4/6 inhibition. PD-0332991 was found to efficiently cross the blood-brain barrier and proved highly effective in suppressing the growth of intracranial GBM xenograft tumors, including those that had recurred after initial therapy with temozolomide. Remarkably, no mice receiving PD-0332991 died as a result of disease progression while on therapy. Additionally, the combination of PD-0332991 and radiation therapy resulted in significantly increased survival benefit compared with either therapy alone. In total, our results support clinical trial evaluation of PD-0332991 against newly diagnosed as well as recurrent GBM, and indicate that Rb status is the primary determinant of potential benefit from this therapy.
Thyroidectomy Practice After Implementation of the 2015 American Thyroid Association Guidelines on Surgical Options for Patients With Well-Differentiated Thyroid Carcinoma (2018)

The updated 2015 American Thyroid Association guidelines implementation was associated with a significant decrease in the rates of both up-front total thyroidectomy and completion thyroidectomy. According to these findings, only 1 of 5 patients who undergoes thyroid lobectomy will require a completion procedure.
