Resistive switching in Ag-Ge-Se with extremely low write currents (2007)

Solid electrolytes such as Ag <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">y</sub> (Ge <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">x</sub> Se <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1-x</sub> ) <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1-y</sub> allow rapid diffusion of metal ions and this makes them suitable for memory applications. The switching mechanism in these materials is based on cation migration from an oxidizable electrode (e.g., Ag) under positive bias and the reduction of the metal ions at the counter electrode (e.g., Pt). A metallic connection forms between the electrodes which is stable when the voltage is switched off but can be dissolved when the voltage polarity is reversed. We present our results on resistive switching in Ag/Ag-Ge-Se/Pt cells which can show a resistance ratio of more than 5 orders of magnitude. The ON resistance depends on the write current which allows for multi-bit data storage. The leakage current in the high resistance state can significantly be reduced by introducing an oxide layer within the chalcogenide film. Then, a current as low as 1 nA is sufficient to switch these cells from a high to a low resistance state demonstrating the possibility of extremely low power consumption.
Classification of the mesophase of di-isobutylsilanediol (1982)

The thermotropic liquid crystal mesophase formed by di-isobutylsilanediol has been known for over twenty-five years, but its nature and structure have remained uncertain and the physical characteristics of the phase appeared unique and quite different from those of any other recognised type of liquid crystal. In a previous preliminary publication, it was suggested that the mesophase of di-isobutylsilanediol is in fact of the discotic type only very recently characterised in certain organic systems. Here we describe more fully our grounds for this suggestion. A model is proposed for the structure of this mesophase; this offers an explanation as to why other dialkylsilanediols do not behave similarly. A reinterpretation of earlier X-ray crystallographic data led us to suggest that the mesophase consists of hydrogen-bonded dimers. The model is supported by data from optical microscopy, thermal analysis and miscibility studies. The optical textures shown by the mesophase and those observed at the crystal mesophase boundary are discussed and compared with those of the discotic phases of the benzene hexa-n-alkanoates.
Recurrent Neural Networks to Correct Satellite Image Classification Maps (2017)

While initially devised for image categorization, convolutional neural networks (CNNs) are being increasingly used for the pixelwise semantic labeling of images. However, the proper nature of the most common CNN architectures makes them good at recognizing but poor at localizing objects precisely. This problem is magnified in the context of aerial and satellite image labeling, where a spatially fine object outlining is of paramount importance. Different iterative enhancement algorithms have been presented in the literature to progressively improve the coarse CNN outputs, seeking to sharpen object boundaries around real image edges. However, one must carefully design, choose, and tune such algorithms. Instead, our goal is to directly learn the iterative process itself. For this, we formulate a generic iterative enhancement process inspired from partial differential equations, and observe that it can be expressed as a recurrent neural network (RNN). Consequently, we train such a network from manually labeled data for our enhancement task. In a series of experiments, we show that our RNN effectively learns an iterative process that significantly improves the quality of satellite image classification maps.

Building intuitive 3D interfaces for virtual reality systems (2007)

An exploration of techniques for developing intuitive, and efficient user interfaces for virtual reality systems. Work seeks to understand which paradigms from the better-understood world of 2D user interfaces remain viable within 3D environments. In order to establish this a new user interface was created that applied various understood principles of interface design. A user study was then performed where it was compared with an earlier interface for a series of medical visualization tasks.

Genetic factors in hypertension (1993)

Genetic approaches to hypertension have the potential to identify many of the primary abnormalities that underlie this disorder. Approaches in experimental animals and humans have advanced to the point that this is no longer merely a possibility but is a tangible reality. Successes in the past year include the mapping of a number of relevant loci and the identification of several mutations that contribute to the pathogenesis of hypertension in animals and humans.
Inhibition of Immature Erythroid Progenitor Cell Proliferation by Macrophage Inflammatory Protein-1α by Interacting Mainly With a C-C Chemokine Receptor, CCR1 (1997)

Several lines of evidence indicate that macrophage inflammatory protein-1alpha (MIP-1alpha) modulates the proliferation of hematopoietic progenitor cells, depending on their maturational stages. To clarify the mechanisms for the modulation of hematopoiesis by this chemokine, we examined the expression of a receptor for MIP-1alpha, CCR1, on bone marrow cells of normal individuals using a specific antibody and explored the effects of MIP-1alpha on in vitro erythropoiesis driven by stem cell factor (SCF) and erythropoietin (Epo). CCR1 was expressed on glycophorin A-positive erythroblasts in addition to lymphocytes and granulocytes. CCR1+ cells, isolated from bone marrow mononuclear cells (BMMNCs) using a cell sorter, comprised virtually all erythroid progenitor cells in the BMMNCs. Moreover, MIP-1alpha inhibited, in a dose-dependent manner, colony formation by burst-forming unit-erythroid (BFU-E), but not by colony forming unit-erythroid (CFU-E), in a methylcellulose culture of purified human CD34+ bone marrow cells. Although reverse-transcription polymerase chain reaction (RT-PCR) showed the presence of CCR1, CCR4, and CCR5 transcripts in CD34+ cells in BM, anti-CCR1 antibodies significantly abrogated the inhibitory effects of MIP-1alpha on BFU-E formation both in a methylcellulose culture and in a single cell proliferation assay of purified CD34+ cells. Although the contribution of CCR4 or CCR5 cannot be completely excluded, these results suggest that MIP-1alpha-mediated suppression of the proliferation of immature, but not mature erythroid progenitor cells, is largely mediated by CCR1 expressed on these progenitor cells.

Public key based authentication for secure integration of sensor data and RFID (2008)

The incorporation of sensor readings into RFID tags creates a significant potential for applications which require environment monitoring as well as asset management and tracking, such as blood storage and management, and on-board aircraft part maintenance. On one hand, the environment history is essential in evaluating health and integrity of objects to be protected, such as blood and aircraft part. On the other hand, the periodic sensing information stored in RFID enables identifying the events of displacing and removal of the objects. However, the benefits of integrating RFID with sensor data are achieved only when the authenticity and integrity of data written to and stored at RFID are ensured. In this paper, we present challenges on secure integration of sensor readings and RFID, and compare security solutions of data integrity and authenticity for resource-constrained RFID tags. For mutual authentication between RFID tags and sensors (or readers), the public key based approaches proves efficient and feasible. We further evaluate different public key based approaches in terms of storage and communication efficiency.

Pathological τ proteins in postencephalitic parkinsonism: Comparison with Alzheimer's disease and other neurodegenerative disorders (1997)

Immunohistochemical and biochemical analyses of hyperphosphorylated tau proteins, the major component of neurofibrillary tangles, were performed in different brain regions from patients presenting with postencephalitic parkinsonism. Neurofibrillary tangles were found in hippocampus, neocortical areas (mostly in supragranular layers), and several subcortical structures. By immunoblotting, a tau protein triplet similar to the one seen in Alzheimer's disease was observed. This biochemical approach allows for the definition of postencephalitic parkinsonism from certain neurodegenerative disorders such as progressive supranuclear palsy and corticobasal degeneration.
Stress relaxation and critical thickness for misfit dislocation formation in (101¯) and (3031¯) InGaN/GaN heteroepitaxy (2012)

Cathodoluminescence imaging was used to study the onset of plastic relaxation and critical thickness for misfit dislocation (MD) formation by basal plane (BP) or nonbasal plane (NBP) slip in In0.09Ga0.91N/GaN heterostructures grown on nonpolar (101¯0) and semipolar (3031¯) substrates. Layers grown on both orientations were shown to stress relax initially via generation of NBP MDs as a result of prismatic slip on inclined m-planes. Analysis of the resolved shear stress on the two slip planes (i.e., basal and an inclined m-plane) reveals a crossover at which the resolved shear stress on the m-planes becomes larger than that on the BP.
Abstract P002: Evidence For Smoking Dependent Genetic Effects on C-reactive Protein Levels in a Multi-ethnic Cohort Setting: The Care Consortium. (2012)

INTRODUCTION: C-reactive protein (CRP) is a heritable biomarker of systemic inflammation and a predictor of cardiovascular disease (CVD). Cigarette smoking is a major risk factor in the development of CVD and has been shown to affect circulating levels of CRP. Therefore, we sought to determine how this important environmental exposure may influence genetic associations with CRP in a multi-ethnic setting. METHODS: Using the ITMAT Broad-CARe (IBC) SNP array, a custom 50,000 SNP gene-centric array having dense coverage of over 2,000 candidate genes for CVD pathways, we performed a meta-analysis of up to 26,065 participants of European descent and 7,584 participants of African descent for association with log-CRP level within smoking status stratum. The 2 smoking strata were: never smokers and ever smokers (comprising of current and former smokers). We conducted IBC-wide association scans for CRP within cohort-, race- and smoking-stratum and meta-analyzed by race. Samples were from the Candidate gene Association Resource (CARe) cohorts (Atherosclerosis Risk in Communities Study, Framingham Heart Study, Cardiovascular Health Study, Cleveland Family Study , Coronary Artery Risk Development in Young Adults Study, Jackson Heart Study, and Multi-Ethnic Study of Atherosclerosis Study). Results were considered to be panel wide statistically significant if p&lt;2.2×10−6. RESULTS: The overall sample size for ever smokers (never smokers) was 11,698 (10,344) in European Americans and 3,448 (4,330) in African Americans. The per-allele beta coefficients for genes previously established to be associated with CRP and present on the IBC chip ( CRP, APOE, GCKR, IL6R, LEPR, HNF1A, NLRP3 ) were very similar in magnitude between smoking strata in European Americans. However, in the African Americans, the estimated per-allele CRP and IL6R betas were 2-times larger for the ever smokers as compared to the never smokers. In the European American analysis, one gene not previously reported for association with CRP reached IBC-wide significance for a CRP-lowering effect in the never smokers ( GSTT1 , p=4.8E-07 for SNP rs405597 ), but not in the ever smokers (p=0.078). CONCLUSION: This large scale candidate gene based meta-analysis identified one novel locus for CRP ( GSTT1 ) associated with serum CRP levels in those reporting having never regularly smoked. Polymorphisms in GSTT1 , which plays a role in detoxification, have previously been reported to interact with smoking for other phenotypes including birth weight and colorectal cancer. We also observed evidence that smoking modifies the effects for previously established loci CRP and IL6R in African Americans. These results may identify important context genetic specific effects that influence chronic inflammation.
Coded-aperture imaging system for reconstructing tomograms of human myocardium (1984)

To increase the detection efficiency and improve the spatial resolution, a coded-aperture imaging method is applied to nuclear medicine. The aperture consists of nine pinholes arranged in a square grid. Three kinds of coding are sequentially used to record the same number of projections including parallax and overlap. The overlapped images are partially separated, and good tomograms of a ring phantom and a human myocardium are reconstructed using a modified backprojection algorithm with variable damping factor.
Automatic selection of social media responses to news (2013)

Social media responses to news have increasingly gained in importance as they can enhance a consumer's news reading experience, promote information sharing and aid journalists in assessing their readership's response to a story. Given that the number of responses to an online news article may be huge, a common challenge is that of selecting only the most interesting responses for display. This paper addresses this challenge by casting message selection as an optimization problem. We define an objective function which jointly models the messages' utility scores and their entropy. We propose a near-optimal solution to the underlying optimization problem, which leverages the submodularity property of the objective function. Our solution first learns the utility of individual messages in isolation and then produces a diverse selection of interesting messages by maximizing the defined objective function. The intuitions behind our work are that an interesting selection of messages contains diverse, informative, opinionated and popular messages referring to the news article, written mostly by users that have authority on the topic. Our intuitions are embodied by a rich set of content, social and user features capturing the aforementioned aspects. We evaluate our approach through both human and automatic experiments, and demonstrate it outperforms the state of the art. Additionally, we perform an in-depth analysis of the annotated ``interesting'' responses, shedding light on the subjectivity around the selection process and the perception of interestingness.
The correlation of chemical structure and electrical conductivity in polypyrrole films by x‐ray photoelectron spectroscopy (1988)

Abstract X‐ray photoelectron spectroscopy was used to track chemical structure changes in conducting polypyrrole films which were electrochemically grown at various current densities. The film structures were correlated to changes in the film electrical conductivities. High resolution spectra of the C 1s, N 1s and O 1s regions were recorded. Concentrations of the charge compensating counter‐ions used in the growth of the film were also monitored and correlated to electrical performance. Results indicated that the films grown at low current densities contained hydroxide anions and deprotonated nitrogen species, while films grown at high current densities contained no hydroxide ions or deprotonated nitrogens and exhibited higher charge removal from the pyrrole ring. At medium current densities, the amount of incorporated dopant anion was maximized.
Acute Hydrocephalus in an Adult Patient Secondary to Unruptured Arteriovenous Malformation (2021)

Acute hydrocephalus as a result of unruptured arteriovenous malformation (AVM) is a rare phenomenon in the adult population. Patients with AVMs typically present with hemorrhage, seizures, or focal neurologic deficits. Hydrocephalus may result from obstructing the native cerebrospinal fluid drainage by the malformation’s architecture. We report a previously healthy 32 year-old male who initially presented to an optometrist with blurry vision, visual obscurations, and papilledema. A large right frontal cerebral AVM with hydrocephalus and papilledema was confirmed by MRI. Unfortunately localized lesions may result in hydrocephalus as a rare presentation in unruptured AVMs.
Influence of the bisphenol structure on the direct synthesis of sulfonated poly(arylene ether) copolymers. I (2003)

Abstract New sulfonated poly(arylene ether sulfone) copolymers with high molecular weights were successfully synthesized with controlled degrees of disulfonation of up to 70 mol % via the direct copolymerization of sulfonated aromatic dihalides, aromatic dihalides, and one of four structurally distinct bisphenols. The disodium salts of the 3,3′‐disulfonated‐4,4′‐dichlorodiphenyl sulfone and 3,3′‐disulfonated‐4,4′‐difluorodiphenyl sulfone comonomers were synthesized via the sulfonation of 4,4′‐dichlorodiphenyl sulfone or 4,4′‐difluorodiphenyl sulfone with 30% fuming sulfuric acid at 110 °C. Four bisphenols (4,4′‐bisphenol A, 4,4′‐bisphenol AF, 4,4′‐biphenol, and hydroquinone) were investigated for the syntheses of novel copolymers with controlled degrees of sulfonation. The composition and incorporation of the sulfonated repeat unit into the copolymers were confirmed by 1 H NMR and Fourier transform infrared spectroscopy. Solubility tests on the sulfonated copolymers confirmed that no crosslinking and probably no branching occurred during the copolymerizations. Tough, ductile films were solvent‐cast that exhibited increased water absorption with increasing degrees of sulfonation. These copolymers are promising candidates for high temperature proton‐exchange membranes in fuel cells, which will be reported separately in part II of this series. © 2003 Wiley Periodicals, Inc.

Allogeneic effector/memory Th-1 cells impair FoxP3+ regulatory T lymphocytes and synergize with chaperone-rich cell lysate vaccine to treat leukemia (2010)

Therapeutic strategies combining the induction of effective antitumor immunity with the inhibition of the mechanisms of tumor-induced immunosuppression represent a key objective in cancer immunotherapy. Herein we demonstrate that effector/memory CD4(+) T helper-1 (Th-1) lymphocytes, in addition to polarizing type-1 antitumor immune responses, impair tumor-induced CD4(+)CD25(+)FoxP3(+) regulatory T lymphocyte (Treg) immunosuppressive function in vitro and in vivo. Th-1 cells also inhibit the generation of FoxP3(+) Tregs from naive CD4(+)CD25(-)FoxP3(-) T cells by an interferon-γ-dependent mechanism. In addition, in an aggressive mouse leukemia model (12B1), Th-1 lymphocytes act synergistically with a chaperone-rich cell lysate (CRCL) vaccine, leading to improved survival and long-lasting protection against leukemia. The combination of CRCL as a source of tumor-specific antigens and Th-1 lymphocytes as an adjuvant has the potential to stimulate efficient specific antitumor immunity while restraining Treg-induced suppression.
