NanoCell Electronic Memories (2003)

NanoCells are disordered arrays of metallic islands that are interlinked with molecules between micrometer-sized metallic input/output leads. In the past, simulations had been conducted showing that the NanoCells may function as both memory and logic devices that are programmable postfabrication. Reported here is the first assembly of a NanoCell with disordered arrays of molecules and Au islands. The assembled NanoCells exhibit reproducible switching behavior and two types of memory effects at room temperature. The switch-type memory is characteristic of a destructive read, while the conductivity-type memory features a nondestructive read. Both types of memory effects are stable for more than a week at room temperature, and bit level ratios (0:1) of the conductivity-type memory have been observed to be as high as 104:1 and reaching 106:1 upon ozone treatment, which likely destroys extraneous leakage pathways. Both molecular electronic and nanofilamentary metal switching mechanisms have been considered, though the evidence points more strongly toward the latter. The approach here demonstrates the efficacy of a disordered nanoscale array for high-yielding switching and memory while mitigating the arduous task of nanoscale patterning.
Boundary Artifact Reduction in View Synthesis of 3D Video: From Perspective of Texture-Depth Alignment (2011)

3D Video (3DV) with depth-image-based view synthesis is a promising candidate of next generation broadcasting applications. However, the synthesized views in 3DV are often contaminated by annoying artifacts, particularly notably around object boundaries, due to imperfect depth maps (e.g., produced by state-of-the-art stereo matching algorithms or compressed lossily). In this paper, we first review some representative methods for boundary artifact reduction in view synthesis, and make an in-depth investigation into the underlying mechanisms of boundary artifact generation from a new perspective of texture-depth alignment in boundary regions. Three forms of texture-depth misalignment are identified as the causes for different boundary artifacts, which mainly present themselves as scattered noises on the background and object erosion on the foreground. Based on the insights gained from the analysis, we propose a novel solution of suppression of misalignment and alignment enforcement (denoted as SMART) between texture and depth to reduce background noises and foreground erosion, respectively, among different types of boundary artifacts. The SMART is developed as a three-step pre-processing in view synthesis. Experiments on view synthesis with original and compressed texture/depth data consistently demonstrate the superior performance of the proposed method as compared with other relevant boundary artifact reduction schemes.

Use of Prothrombin Complex Concentrates in Hemophiliacs with Inhibitors: Clinical and Laboratory Studies (1978)

Nine patients with severe classic hemophilia and inhibitors against factor VIII were treated for 156 bleeding episodes with 503 infusions of Proplex, Konyne, or Auto-Factor IX, three preparations of prothrombin complex concentrates (PCCs). Approximately two thirds of the bleeding episodes were managed successfully. Although the prothrombin time (PT) and partial thromboplastin time (PTT) were shortened after most PCC infusions, there was no evidence of disseminated intravascular coagulation. The degree of shortening of PT or PTT was not related to the particular PCC preparation used, dose, or cessation of hemorrhage. All PCC preparations contained activated clotting factors, as manifested by their ability to shorten the PTT of normal plasma, factor-VIII-deficient plasma, and factor-IX-deficient plasma. Shortening, which was greater with Auto-Factor IX than with the other products, was inhibited partially by a factor IX antibody and blocked completely by prolonged incubation with plasma. Although the nature of the procoagulant material in PCCs is uncertain, these products are of proven benefit to hemophilic patients with high-titer inhibitors. Side effects have been minimal and inhibitor titers have not risen.
SAR pattern perturbations from resonance effects in water bolus layers used with superficial microwave hyperthermia applicators (2002)

This study examines the effect of various thickness water bolus coupling layers on the SAR (Specific Absorption Rate) patterns from Dual Concentric Conductor (DCC) based Conformal Microwave Array (CMA) superficial hyperthermia applicators. Previous theory has suggested that water bolus coupling layers can be considered as a dielectric resonator; therefore, it is possible for the impinging electric field to stimulate volume oscillations and surface wave oscillations inside the water bolus. These spurious oscillations will destructively or constructively interact with the impinging electric field to cause a perturbation of the applicator SAR pattern. An experiment was designed which consisted of mapping the electric field produced by a four element DCC CMA applicator in liquid muscle phantom at depths of 5 and 10mm in front of four different thickness water boli; 0 (no bolus) 4, 9 and 13mm. Using the Finite Difference Time Domain (FDTD) method, SAR distributions were calculated for similar test cases. It was found that for water bolus thicknesses of 9mm or greater, there is a marked perturbation of both experimental and theoretical SAR distributions. It is believed that this perturbation is experimental confirmation of the volume and surface wave oscillation theory described by previous investigators.
Chronic Cyclodextrin Treatment of Murine Niemann-Pick C Disease Ameliorates Neuronal Cholesterol and Glycosphingolipid Storage and Disease Progression (2009)

Treatment with CD delayed clinical disease onset, reduced intraneuronal storage and secondary markers of neurodegeneration, and significantly increased lifespan of both Npc1(-/-) and Npc2(-/-) mice. In contrast, CD failed to ameliorate cholesterol or glycosphingolipid storage in GM1 gangliosidosis and MPS IIIA disease. Understanding the mechanism(s) by which CD leads to reduced neuronal storage may provide important new opportunities for treatment of NPC and related neurodegenerative diseases characterized by cholesterol dyshomeostasis.
Register allocation deconstructed (2009)

Register allocation is a fundamental part of any optimizing compiler. Effectively managing the limited register resources of the constrained architectures commonly found in embedded systems is essential in order to maximize code quality. In this paper we deconstruct the register allocation problem into distinct components: coalescing, spilling, move insertion, and assignment. Using an optimal register allocation framework, we empirically evaluate the importance of each of the components, the impact of component integration, and the effectiveness of existing heuristics. We evaluate code quality both in terms of code performance and code size and consider four distinct instruction set architectures: ARM, Thumb, x86, and x86-64. The results of our investigation reveal general principles for register allocation design.
Impact of gestrinone on the course of asymptomatic endometriosis. (1987)

A new drug, gestrinone, was subjected to the first double blind, randomised placebo controlled trial of any treatment of endometriosis. The disease deteriorated in eight (47%) of the 17 patients prescribed placebo (95% confidence limits 23% and 71%) compared with none of the 18 patients prescribed gestrinone (p = 0.002). There was a difference in elimination of the endometriosis in the gestrinone group compared with placebo but this was not statistically significant (p = 0.057). There was a significant difference in improvement of the disease in the gestrinone group compared with placebo (p = 0.004), confirming that gestrinone is an effective treatment of endometriosis. Endometriosis deteriorates in at least 23% of patients; as it is impossible to predict in whom this will happen, treatment appears to be warranted in all cases.
Large Cell Lymphoma Transformation of Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma (2001)

We studied 7 cases of large cell transformation of chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) immunophenotyped by multiparameter flow cytometry. The 6 women and 1 man ranged in age from 45 to 91 years. All had previous or concurrent evidence of CLL/SLL. Morphologic features and sites of involvement of the diffuse large B-cell lymphoma (DLBCL) were heterogeneous; 2 cases had paraimmunoblastic morphologic features. Six DLBCLs had an immunophenotype consistent with CLL: CD19+, CD5+, CD23+, and FMC7 negative (3 cases) or very dim (2 cases); 1 case was not studied for FMC7. CD20 was dim in 3 of these, moderate to bright in 2, and variable in 1. Surface immunoglobulin was dim in 2 cases and moderate or bright in 4. Five of 6 expressed CD38. Comparison with the immunophenotypes of the previous or coexistent CLL/SLL (4 of 6 cases) revealed minor modulations in antigen expression but no major alterations. The seventh DLBCL lacked CD5 expression, but otherwise had immunophenotypic features similar to CLL. These findings indicate that DLBCL arising in CLL/SLL tends to retain a CLL immunophenotype, in contrast with de novo CD5+ large cell lymphomas that uncommonly express such a phenotype.
Current–voltage characteristics of an LB monolayer of didecylammonium tricyanoquinodimethanide measured between macroscopic gold electrodes (2002)

Didecylammonium tricyanoquinodimethanide, a zwitterionic molecule of the type D+–π–A− (where D+ = ammonium, π = ethylene “bridge”, and A− = tricyanoquinodimethanide), forms a Pockels–Langmuir monolayer film at the air–water interface. The molecules can be transferred quantitatively as a Langmuir–Blodgett (LB) monolayer onto a gold surface. Using the “cold-gold” evaporation technique, a set of several macroscopic gold electrode pads were evaporated atop the LB monolayer. Pads which had macroscopic defects were electrical short circuits, but across many pads finite electrical currents were observed as a function of applied bias; however, no obvious electrical rectification was found. The monolayer thickness on a gold substrate was measured by XPS to be ∼22 Å. Reflection-absorption infrared spectroscopy (RAIRS) indicates that the molecules have a preferred orientation in the film, but are not well ordered. Angle-resolved X-ray photoelectron spectroscopy (XPS) suggests that many of the molecules are oriented anti-parallel to each other, possibly because dipole–dipole forces favor such an anti-parallel orientation. This latter observation helps to explain why no electrical rectification was found.
Long-Chain Linear C19 and C23 Monomers and Polycondensates from Unsaturated Fatty Acid Esters (2011)

Isomerizing alkoxycarbonylation of methyl oleate and ethyl erucate, respectively, yielded dimethyl 1,19-nonadecanedioate and diethyl 1,23-tricosanedioate in >99% purity. With [κ2-(P̂ P)Pd(OTf)][OTf] as a defined catalyst precursor (P̂P = 1,2-bis[(di-tert-butylphosphino)methyl]benzene) the reaction can be carried out without the need for additional added diphosphine. Saponification of the diesters yielded 1,19-nonadecanedicarboxylic acid and 1,23-tricosanedicarboxylic acid in >99% purity. By ruthenium-catalyzed reduction of the diesters with H2, 1,19-nonadecanediole and 1,23-tricosanediole were formed in high yield and purity (>99%). From the latter, 1,19-nonadecanediamine and 1,23-tricosanediamine were generated. Polyesters with commercially available shorter-chain petrochemical or renewable diols exhibit high melting points due to the crystallizable long-chain methylene segments from the dicarboxylic acid component, e.g., poly[1,6-hexadiyl-1,23-tricosanedioate] Tm 92, Tc 75 °C. Thermal properties of novel long-chain polyamides are reported.
Engineered Alginate Hydrogels for Effective Microfluidic Capture and Release of Endothelial Progenitor Cells from Whole Blood (2011)

Microfluidic adhesion-based cell separation systems are of interest in clinical and biological applications where small sample volumes must be processed efficiently and rapidly. While the ability to capture rare cells from complex suspensions such as blood using microfluidic systems has been demonstrated, few methods exist for rapid and nondestructive release of the bound cells. Such detachment is critical for applications in tissue engineering and cell-based therapeutics in contrast with diagnostics wherein immunohistochemical, proteomic, and genomic analyses can be carried out by simply lysing captured cells. This paper demonstrates how the incorporation of four-arm amine-terminated poly(ethylene glycol) (PEG) molecules along with antibodies within alginate hydrogels can enhance the ability of the hydrogels to capture endothelial progenitor cells (EPCs) from whole human blood. The hydrogel coatings are applied conformally onto pillar structures within microfluidic channels and their dissolution with a chelator allows for effective recovery of EPCs following capture.
Effect of oscillator phase noise on uplink performance of large MU-MIMO systems (2012)

The effect of oscillator phase noise on the sum rate performance of a frequency selective multi-user multiple-input multiple-output (MU-MIMO) uplink channel is studied under imperfect channel state information. A maximum ratio combining detection strategy is employed by the base station (BS) (having a large antenna array of M elements), and an analytical expression of a lower bound on the sum capacity of the system is derived. It is shown that an array power gain of O(√M) is achievable. It is also observed that phase noise effectively limits the fraction of the time used for information transmission and the number of users in the system. Finally it is concluded that, phase noise degrades the performance but does not eliminate the fundamental gains of a Large Scale Antenna System (LSAS), i.e., power efficiency and high sum rate performance with low complexity receiver processing.
A Mathematical Model and Calibration Procedure for Galvanometric Laser Scanning Systems (2011)

Laser galvanometric scanning systems are commonly used in various fields such as three dimensional scanning, medical imaging, material processing, measurement devices and laser display systems. The systems of such kind suffer from distortions. On top of that they do not have a center of projection, which makes it impossible to use common projector calibration procedures. The paper presents a novel mathematical model to predict the image distortions caused by galvanometric mirror scanning systems. In addition, we describe a calibration procedure for recovering its intrinsic and extrinsic parameters.
Glial Progenitor Cell–Based Treatment and Modeling of Neurological Disease (2012)

The diseases of myelin are among the most prevalent and disabling conditions in neurology. These diseases include both the vascular and inflammatory demyelinating disorders of adulthood, as well as the childhood leukodystrophies and cerebral palsy. These fundamentally glial disorders may be amenable to treatment by glial progenitor cells (GPCs), which give rise to astroglia and myelin-producing oligodendrocytes. Given the development of new methods for generating and isolating human GPCs, the myelin disorders may now be compelling targets for cell-based therapy. In addition, the efficient engraftment and expansion of human GPCs in murine hosts has led to the development of human glial chimeric mouse brains, which provides new opportunities for studying the species-specific roles of human glia in cognition, as well as in disease pathogenesis.
Intentional and Unintentional Weight Loss Increase Bone Loss and Hip Fracture Risk in Older Women (2003)

Older women who experience weight loss in later years have increased rates of hip-bone loss and a two-fold greater risk of subsequent hip fracture, irrespective of current weight or intention to lose weight. These findings indicate that even voluntary weight loss in overweight elderly women increases hip fracture risk.

Gα COOH-Terminal Minigene Vectors Dissect Heterotrimeric G Protein Signaling (2002)

The COOH-termini of heterotrimeric guanine nucleotide-binding protein (G protein) alpha subunits (Galpha) are critical for both binding to their cognate G protein-coupled receptors (GPCRs) and determining specificity. Additionally, synthetic peptides corresponding to the COOH-terminus can serve as competitive inhibitors of receptor-G protein interactions, presumably by blocking the site on the GPCR that normally binds the G protein. To selectively antagonize G protein signal transduction events, we have generated minigene vectors that encode 14 unique COOH-terminal sequence for the 16 Galpha subunits. Minigene vectors expressing Galpha COOH-terminal peptides, or the control minigene vector, which expresses the inhibitory Galpha subunit (G(i)) peptide in random order, can be systematically introduced into cells by transfection and used to determine which G protein underlies a given GPCR-mediated response. Because Galpha COOH-terminal minigene vectors selectively block signal transduction through a given G protein, they are a powerful tool for dissecting out which G protein mediates a given biochemical or physiological function. This also provides a novel strategy for exploring the coupling mechanisms of receptors that interact with multiple G proteins, as well as for teasing out the downstream responses mediated by a specific G protein.
Interference Reduction in Mobile Ad Hoc and Sensor Networks (2011)

There are still a lot of open questions in the field of mobile ad hoc networks (MANETs) and sensor networks. If a topology incurs a large interference, either many communication signals sent by nodes will collide, or the network may experience a serious delay at delivering the data for some nodes, and even consume more energy. So, we reach the conclusion that interference imposes a potential negative impact on the performance of wireless networks. In the last few years, researchers actively explored topology control approaches for such networks. The motivation of topology control (TC) is to maintain the connectivity of the network, reduce the node degree and thereby reduce the interference, and reduce power consumption in the sensor nodes. Some literatures have pointed out that a node can interfere with another node even if it is beyond its communication range. To improve the network performance, designing topology control algorithms with consideration of interference is imminent and necessary. Since, it leads to fewer collisions and packet retransmissions, which indirectly reduces the power consumption and extends the lifetime of the network. In this paper, we propose a new interference-aware connected dominating set-based (IACDS) topology construction algorithm, namely, IACDS algorithm, a simple, distributed, interference-aware and energy-efficient topology construction mechanism that finds a sub-optimal connected dominating set (CDS) to turn unnecessary nodes off while keeping the network connected and providing complete communication coverage with minimum interference. IACDS algorithm utilizes a weighted distance-energy-interference-based metric that permits the network operator to trade off the lengths of the branches (distance) for the robustness and durability of the topology (energy and interference).

Cryptographic sealing for information secrecy and authentication (1981)

The problem of computer security can be considered to consist of four distinct components: secrecy (ensuring that information is only disclosed to authorized users), authentication (ensuring that information is not forged), integrity (ensuring that information is not destroyed), and availability (ensuring that access to information can not be maliciously interrupted). The paper describes a new protection mechanism called cryptographic sealing that provides primitives for secrecy and authentication. The mechanism is enforced with a synthesis of classical cryptography, public-key cryptography, and a threshold scheme.
