Diffusion tensor imaging tractography to visualize the relationship of the optic radiation to epileptogenic lesions prior to neurosurgery (2011)

The optic radiation shows significant anatomic variability, but can be reliably delineated by tractography. Because surgical disruption of the optic radiation has serious consequences for the patient, DTI tractography is a useful technique in this population. Future integration with real-time neuronavigation will minimize the risks of neurosurgery.
Marine Natural Products. XXXI. Structure-Activity Correlation of a Potent Cytotoxic Dimeric Macrolide Swinholide A, from the Okinawan Marine Sponge Theonella swinhoei, and Its Isomers. (1994)

Acidic treatment of swinholide A (1), which was characterized as the major cytotoxic macrolide from the Okinawan marine sponge Theonella swinhoei, provided several isomeric macrolides having different size of the dilactone ring structure. From the structure-activity correlation viewpoint, the in vitro cytotoxicities and in vivo antitumor activities of these dimeric macrolides, together with two monomeric macrolides which were synthesized from 1, have been examined.
Field-flow fractionation of chromosomes (1991)

The work done on this project is divided into two principal areas. The first involves the application of sedimentation/steric FFF to metaphase chromosomes in an attempt to fractionate the chromosomes according to their size. The preparation of chromosomes from a number of organisms was attempted; procedures were finally worked out in collaboration with Los Alamos National Laboratory for the preparation of metaphase chromosomes from Chinese hamster cells. After extensive experimental work was done to identify suitable operating conditions, the partial fractionation of the Chinese hamster chromosomes was achieved. In the second component of the project, flow FFF was applied to the separation of DNA fragments. Figures are provided that show considerable success in the separation of plasmid digests and in the separation of single from double stranded DNA under 10{sup 4} base pairs. Preliminary work was done on DNA fragments having a size greater than 10{sup 4} base pairs. This work has served to establish the inversion point for DNA.
Wavelength tuning and stabilization of microring-based filters using silicon in-resonator photoconductive heaters (2015)

We demonstrate that n-doped resistive heaters in silicon waveguides show photoconductive effects with high responsivities. These photoconductive heaters, integrated into microring resonator (MRR)-based filters, were used to automatically tune and stabilize the filter's resonance wavelength to the input laser's wavelength. This is achieved without requiring dedicated defect implantations, additional material depositions, dedicated photodetectors, or optical power tap-outs. Automatic wavelength stabilization of first-order MRR and second-order series-coupled MRR filters is experimentally demonstrated. Open eye diagrams were obtained for data transmission at 12.5 Gb/s while the temperature was varied by 5 °C at a rate of 0.28 °C/s. We theoretically show that series-coupled MRR-based filters of any order can be automatically tuned by using photoconductive heaters to monitor the light intensity in each MRR, and sequentially aligning the resonance of each MRR to the laser's wavelength.
Framing U-Net via Deep Convolutional Framelets: Application to Sparse-view CT (2017)

X-ray computed tomography (CT) using sparse projection views is a recent approach to reduce the radiation dose. However, due to the insufficient projection views, an analytic reconstruction approach using the filtered back projection (FBP) produces severe streaking artifacts. Recently, deep learning approaches using large receptive field neural networks such as U-Net have demonstrated impressive performance for sparse- view CT reconstruction. However, theoretical justification is still lacking. Inspired by the recent theory of deep convolutional framelets, the main goal of this paper is, therefore, to reveal the limitation of U-Net and propose new multi-resolution deep learning schemes. In particular, we show that the alternative U- Net variants such as dual frame and the tight frame U-Nets satisfy the so-called frame condition which make them better for effective recovery of high frequency edges in sparse view- CT. Using extensive experiments with real patient data set, we demonstrate that the new network architectures provide better reconstruction performance.
Optimal Graft Thickness for Different Sizes of Tympanic Membrane Perforation in Cartilage Myringoplasty: A Finite Element Analysis (2007)

On the basis of our biomechanical analysis, the optimal thickness of a cartilage graft for myringoplasty appears to be 0.1 to 0.2 mm for medium and large TM perforations. For small perforations, a cartilage of less than 1.0 mm is a good compromise between mechanical stability and low acoustic transfer loss.
Digital signatures with RSA and other public-key cryptosystems (1984)

Public-key signature systems can be vulnerable to attack if the protocols for signing messages allow a cryptanalyst to obtain signatures on arbitrary messages of the cryptanalyst's choice. This vulnerability is shown to arise from the homomorphic structure of publickey systems. A method of foiling the attack is described.
Performance Analysis of Secure Unified Communications in the VMware-Based Cloud (2015)

Unified communications as a service (UCaaS) can be regarded as a cost-effective model for on-demand delivery of unified communications services in the cloud. However, addressing security concerns has been seen as the biggest challenge to the adoption of IT services in the cloud. This study set up a cloud system via VMware suite to emulate hosting unified communications (UC), the integration of two or more real time communication systems, services in the cloud in a laboratory environment. An Internet Protocol Security (IPSec) gateway was also set up to support network-level security for UCaaS against possible security exposures. This study was aimed at analysis of an implementation of UCaaS over IPSec and evaluation of the latency of encrypted UC traffic while protecting that traffic. Our test results show no latency while IPSec is implemented with a G.711 audio codec. However, the performance of the G.722 audio codec with an IPSec implementation affects the overall performance of the UC server. These results give technical advice and guidance to those involved in security controls in UC security on premises as well as in the cloud.
The Focusing View-Finder Problem in Television Cameras (1943)

The technical excellence of a television program may frequently depend on the characteristics of the view finder used in the television camera. Conditions peculiar to television make it desirable that television-camera view finders be of the focusing type. The requirements of an ideal view finder of this type are discussed. During the past ten years a number of view-finder arrangements have been investigated in connection with the development of television cameras. Several of these are described and their relative merits indicated.
On the sound field of a resilient disk in free space (2008)

Radiation characteristics are calculated for a circular planar sound source in free space with a uniform surface pressure distribution, which can be regarded as a freely suspended membrane with zero mass and stiffness. This idealized dipole source is shown to have closed form solutions for its far-field pressure response and radiation admittance. The latter is found to have a simple mathematical relationship with the radiation impedance of a rigid piston in an infinite baffle. Also, a single expansion is derived for the near-field pressure field, which degenerates to a closed form solution on the axis of symmetry. From the normal gradient of the surface pressure, the surface velocity is calculated. The near-field expression is then generalized to an arbitrary surface pressure distribution. It is shown how this can be used as a simplified solution for a rigid disk in free space or a more realistic sound source such as pre-tensioned membrane in free space with non-zero mass and a clamped rim.
[Mechanical analysis on a new type of biodegradable magnesium-alloy stent]. (2009)

Biodegradable magnesium-alloy stents have been employed in animal experiments and clinical researches in recent years. Magnesium-alloy stents have been reported to be biocompatible, and degradable due to corrosion after being implanted into blood vessel. However, magnesium alloy is brittle compared with stainless steel. This may cause strut break under large deformation. In this paper, a finite element model of magnesium-alloy stent was set up, with reference to pictures from Biotronik Corporation, to simulate the expanding and bending processes. The results of analysis show that the maximum strain during expanding reaches 20%, being greater than the elongation limit of the commercially available magnesium alloys. Therefore, to avoid strut breakage during expanding, the magnesium alloys should be custom-made. The plasticity of the material should be improved by grain refinement processes before practicable magnesium-alloy stents could be developed.
Data disclosure risk evaluation (2009)

Many companies have to share various types of information containing private data without being aware about the threats related to such non-controlled disclosure. Therefore we propose a solution to support these companies to evaluate the disclosure risk for all their types of data; by recommending the safest configurations using a smart bootstrapping system.

IC Cloud: A Design Space for Composable Cloud Computing (2010)

Cloud computing has attracted great interest from both academic and industrial communities. Different paradigms, architectures and applications have emerged. However, to the best of our knowledge, only few efforts have been devoted to study the architecture as well as implementation details for building up a cloud computing system. In this paper, we present our design and implementation of\textit{Imperial College Cloud (IC Cloud)}. The goal of IC Cloud is to provide a generic design space where various cloud computing architectures and implementation strategies can be systematically studied. The IC Cloud design strictly follows the SOA principle and incorporates a highly flexible system design approach.

EFFECT OF GRIT-BLASTING AND PLASMA ETCHING ON THE SURFACE COMPOSITION AND SURFACE ENERGY OF GRAPHITE/EPOXY COMPOSITES (2005)

Earlier DCB and lap shear failure results indicated that grit blasting and plasma etching of graphite/epoxy composites produced strong durable bonds.Grit blasting and oxygen plasma etching of graphite/epoxy composites were analyzed for their effects on surface energy, roughness, and changes in surface chemistry.Two systems of epoxy resin material were analyzed.Surface energy results for grit blasted composite panels showed a significant increase in surface energy.However, upon roughness corrections the surface energy was calculated to be lower.The resulting change in surface energy after roughness corrections is due to a change in surface chemistry.XPS results indicated that grit blasting and oxygen plasma etching removed surface contamination from a fluorinated mold release agent as well as introduce new functional groups onto the composite surface.Interaction of these functional groups with a brominated epoxy suggests covalent bonding is an important factor in the adhesion of graphite/epoxy composites.
Pulse-dependent analyses of percussive music (2002)

We report on a method of automatic extraction of a metrical attribute from percussive music audio signals: the smallest rhythmic pulse, called the ìtickî. The relevance of use of this feature in the framework of subsequent analyses is discussed and evaluated.
Data and Visualization Corridors: Report on the 1998 DVC Workshop Series (1998)

The Department of Energy and the National Science Foundation sponsored a series of workshops on data manipulation and visualization of large-scale scientific datasets. Three workshops were held in 1998, bringing together experts in high-performance computing, scientific visualization, emerging computer technologies, physics, chemistry, materials science, and engineering. These workshops were followed by two writing and review sessions, as well as numerous electronic collaborations, to synthesize the results. The results of these efforts are reported here. Across the government, mission agencies are charged with understanding scientific and engineering problems of unprecedented complexity. The DOE Accelerated Strategic Computing Initiative, for example, will soon be faced with the problem of understanding the enormous datasets created by teraops simulations, while NASA already has a severe problem in coping with the flood of data captured by earth observation satellites. Unfortunately, scientific visualization algorithms, and high-performance display hardware and software on which they depend, have not kept pace with the sheer size of emerging datasets, which threaten to overwhelm our ability to conduct research. Our capability to manipulate and explore large datasets is growing only slowly, while human cognitive and visual perception are an absolutely fixed resource. Thus, there is a pressing need for new methods of handling truly massive datasets, of exploring and visualizing them, and of communicating them over geographic distances. This report, written by representatives from academia, industry, national laboratories, and the government, is intended as a first step toward the timely creation of a comprehensive federal program in data manipulation and scientific visualization. There is, at this time, an exciting confluence of ideas on data handling, compression, telepresence, and scientific visualization. The combination of these new ideas, which we refer to as Da ta and Visualization Corridors (DVC), can raise scientific data understanding to new levels and will improve the way science is practiced
High-bandwidth radio frequency Coulter counter (2005)

We demonstrate a method for high-bandwidth, high-sensitivity particle sensing and cell counting in a microfluidic system. Our approach employs a tuned radiofrequency probe, which forms the radiofrequency analog of a Coulter counter. By measuring the reflected rf power, this approach provides an unprecedented detection rate, with a theoretical bandwidth in excess of 10 MHz. Particle detection was performed in a continuous flow mode in a microfluidic channel, using 15μm diameter polystyrene beads suspended in a sucrose-saline solution. We demonstrate 30 kHz counting rates and show high-resolution bead time-of-flight data, comprising the fastest electronic particle detection on-chip to date.
Learning to Predict the Future using Web Knowledge and Dynamics (2012)

Mark Twain famously said that "the past does not repeat itself, but it rhymes." In the spirit of this reflection, we present novel algorithms and methods for leveraging large-scale digital histories and human knowledge mined from the Web to make real-time predictions about the likelihoods of future human and natural events of interest. The Web is a dynamic being, with constantly updating content, which is entangled with sophisticated user behaviors and interactions. Some of these behaviors have the ability to convey current trends in the present, e.g., economical growth (predicting automobile sales based on query volume [6]), popular movies [4], and political unrest [1, 3, 5]. We mine the ever-changing Web content and user Web behavior. We show that, not only the dynamics itself can be predicted, but also that it can be used for future real-world event prediction. We mine decades of news reports (1851 - 2010) from the New York Times (NYT), and describe how we can learn to predict the future by generalizing sets of concrete transitions in sequences of reported news events. In addition to the news corpora, we leverage data from freely available Web resources, including Wikipedia, FreeBase, OpenCyc, and GeoNames, via the LinkedData platform [2]. The goal is to build predictive models that generalize from specific sets of sequences of events to provide likelihoods of future outcomes, based on patterns of evidence observed in near-term Web activities. We propose the methods as a means of generating actionable forecasts in advance of the occurrence of target events in the world. This thesis is one of the first works to demonstrate general, unrestricted artificial-intelligence prediction capacity. We present methods derived from heterogeneous Web sources to make knowledge-intensive reasoning about causality and future event prediction, using both automatic feature extraction and novel algorithms for generalizing over historical examples.
High-speed performance of OMCVD grown InAlAs/InGaAs MSM photodetectors at 1.5 mu m and 1.3 mu m wavelengths (1989)

A report is presented on the fabrication of high-speed In/sub 0.53/Ga/sub 0.47/As metal-semiconductor-metal (MSM) photodetectors incorporating a high-quality lattice-matched InAlAs barrier enhancement layer, grown by organometallic chemical vapor deposition (OMCVD). Fast responses of approximately 55 ps full-width half-maximum at 1.5 mu m and approximately 48 ps at 1.3 mu m wavelengths are observed, corresponding to intrinsic device bandwidths of approximately 8 GHz and approximately 11 GHz, respectively. The absence of any tail to the pulse response, and of any low-bias DC gain, indicates a low-trap density at the InAlAs/InGaAs heterointerface. Bias independent dark currents of 10-20 mu A are observed below breakdown, which occurred at >30 V in devices with a 500-A-thick InAlAs layer.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

An equalizer design technique for the PCM modem: a new modem for the digital public switched network (1998)

Modems designed for the public switched telephone network (PSTN) have conventionally been based on modeling assumptions which view the PSTN connection as an essentially analog medium. However, as the PSTN evolves toward all digital transport and switching, and particularly as major traffic sources, such as Internet service providers, increasingly have direct digital connections to the PSTN, it is appropriate to revisit the model assumptions. Recently, several modem and chipset manufacturers have announced "56 K" modems based on an emerging system paradigm in which one user (a residential Internet subscriber) has an analog connection to the PSTN, and the other (an Internet service provider) has a digital one. ITU-T is expected to finalize details of a corresponding recommendation in 1998. With this configuration, modem designs based on signaling with the /spl mu/-law alphabet become feasible, and the conventional Shannon limit disappears as the quantization noise is avoided. Thus, the conventional Shannon limit of about 36 kb/s can be beaten, and it is possible to approach the digital transmission rate of 64 kb/s. Modems employing this general approach have become known as /spl mu/-law or pulse-code modulation (PCM) modems. In this paper we present a signaling technique and the sampling theory based on this technique, display the structure and operating principles of a PCM modem equalizer, and show how this equalizer problem can be cast in the language of multiinput-multioutput (MIMO) system theory.
