Photon tunneling microscopy of diamond-turned surfaces (1993)

The photon tunneling microscope's high-resolution, large-field, and real-time three-dimensional display with profilometry and continuously variable perspective make it a powerful tool for analysis of diamond-turned surfaces.
The heavy traffic approximation for single server queues in series (1973)

A tandem queue with K single server stations and unlimited interstage storage is considered. Customers arrive at the first station in a renewal process, and the service times at the various stations are mutually independent i.i.d. sequences. The central result shows that the equilibrium waiting time vector is distributed approximately as a random vector Z under traffic conditions (meaning that the system traffic intensity is near its critical value). The weak limit Z is defined as a certain functional of multi-dimensional Brownian motion. Its distribution depends on the underlying interarrival and service time distributions only through their first two moments. The outstanding unsolved problem is to determine explicitly the distribution of Z for general values of the relevant parameters. A general computational approach is demonstrated and used to solve for one special case.
Ring opening metathesis polymerization of cyclic alkenes containing heteroatoms (1994)

Abstract The Ring Opening Metathesis Polymerization (ROMP) of a series of cyclic alkenes bearing heteroatom functionality has been performed using a classical WCl 6 ‐based catalyst system. All of the alkenes studied exhibited significantly slower polymerization rates compared with the hydrocarbon monomer dicyclopentadiene (DCPD), this being most pronounced for monomers containing a tertiary nitrogen atom substituted at the 2 position of the norbornene skeleton. Cyclic alkene anhydrides, prepared by the Diels‐Alder addition of cyclopentadiene to maleic and itaconic anhdrides, were found to be polymerizable with high yields giving cross‐linked polymers which exhibited very high glass transition temperatures. Monofunctional cyclic imide derivatives of the cyclopentadiene‐itaconic anhydride adduct were found to be polymerizable to moderate molecular weight thermoplastic materials with high glass transition temperatures, whilst difunctional cyclic imide derivatives led to cross‐linked thermoset polymers. The solution copolymerizations of the cyclopentadiene‐maleic anhydride adduct with DCPD, and of a cyclic imide derivative of the cyclopentadiene‐itaconic anhydride adduct with DCPD, were carried out to form copolymers in high yields having glass transition temperatures intermediate between those of the respective homopolymers.
Trusted P2P Media Delivery to Mobile Devices (2010)

Broadband Internet connectivity has reached mobile devices. Smart Phones are the Internet access devices of choice for a whole new generation of users. Data of all forms and shapes is becoming easily accessible: large multi-media files are being routinely downloaded onto a plethora of end user devices. Peer-to-peer content delivery enables massive scale in the amount of data volume that can be efficiently delivered. The openness of delivery demands adaptive and robust management of intellectual property rights. In this paper we describe a framework and its implementation to address the central issues in content delivery: a scalable peer-to-peer-based content delivery model, paired with a secure access control model that enables data providers to reap a return from making their original content available. Peers that contribute to the content delivery are also rewarded. Our prototype implementation - which includes a client for the Android platform for mobile phones - serves as proof of concept for our approach.
Molecular Sieving in Periodic Free-Energy Landscapes Created by Patterned Nanofilter Arrays (2006)

We present an experimental study of Ogston-like sieving process of rodlike DNA in patterned periodic nanofluidic filter arrays. The electrophoretic motion of DNA through the array is described as a biased Brownian motion overcoming periodically modulated free-energy landscape. A kinetic model, constructed based on the equilibrium partitioning theory and the Kramers theory, explains the field-dependent mobility well. We further show experimental evidence of the crossover from Ogston-like sieving to entropic trapping, depending on the ratio between nanofilter constriction size and DNA size.
A novel technique to use scratch-pad memory for stack management (2007)

Extensive work has been done for optimal management of scratch-pad memory (SPM) all assuming that the SPM is assigned a fixed address space. The main target objects to be placed on the SPM have been code and global memory since their sizes and locations are not changed dynamically. We propose a novel idea of dynamic address mapping of SPM with the assistance of memory management unit (MMU). It allows us to use SPM for stack management without architecture modification and complier assistance. The proposed technique is orthogonal to the previous works so can be used at the same time. Experiments results show that the proposed technique results in average performance improvement of 13% and energy savings of 12% observed compared to using only external DRAM. And it also gives noticeable speed up and energy saving against a typical cache solution for stack data.
Optical measurement of the free spectral range and spacing of plane and confocal Fabry-Perot interferometers (1990)

An improved optical method has been developed to determine the free spectral range (FSR) and spacing of Fabry-Perot interferometers (FPIs), based on accurately reproducible measurements of the absolute frequencies of FPI transmission maxima using a tunable cw dye laser and a lam bdameter. The method may be of interest for applications when the FSR of an FPI must be determined with very high accuracy, e.g., in cases of low finesse FPIs or high finesse temperature-stabilized confocal etalons, which provide frequency marks in laser spectroscopic experiments.
Light-Emitting Hyperbolic Metasurfaces at Telecom Frequencies (2016)

We demonstrate light-emitting hyperbolic metasurfaces in the 1200-1600nm spectral range. The multilayer configuration, ideal for planar integration, enables characterization of hyperbolic dispersion by polarization anisotropy of photoluminescence.

Interference channels (1978)

An interference channel is a communication medium shared by M sender-receiver pairs. Transmission of information from each sender to its corresponding receiver interferes with the communications between the other senders and their receivers. This corresponds to a frequent situation in communications, and defines an <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">M</tex> -dimensional capacity region. In this paper, we obtain general bounds on the capacity region for discrete memoryless interference channels and for linear-superposition interference channels with additive white Gaussian noise. The capacity region is determined in special cases.
Multivariate Resource Performance Forecasting in the Network Weather Service (2002)

This paper describes a new technique in the Network Weather Service for producing multi-variate forecasts. The new technique uses the NWSs univariate forecasters and emprically gathered Cumulative Distribution Functions (CDFs) to make predictions from correlated measurement streams. Experimental results are shown in which throughput is predicted for long TCP/IP transfers from short NWS network probes.
Guidance for the management of hirsutism (2005)

Approximately 80% of women are affected by the presence of excessive hair growth in a 'male-like' pattern. Excessive facial hair in particular can be a source of distress to such women and can lead to psychological problems such as anxiety, depression and a reduced quality of life.Current cosmetic methods of hair removal include shaving, depilatories, waxing, plucking, laser, intense pulsed light (IPL) and electrolysis.A topical treatment cream such as eflornithine 11.5% can slow hair growth and thus reduce the frequency of the need for hair removal. This treatment can be used effectively in conjunction with hair removal methods.
Immunization with a<i>Pseudomonas aeruginosa</i>1244 Pilin Provides O-Antigen-Specific Protection (2008)

The O antigen is both a major structural outer membrane component and the dominant epitope of most gram-negative bacteria. Pseudomonas aeruginosa 1244 produces a type IV pilus and covalently links an O-antigen repeating unit to each pilin monomer. Here we show that immunization of mice with pure pilin from strain 1244 by use of either the mouse respiratory model or the thermal injury model resulted in protection from challenge with a pilus-null O-antigen-producing 1244 mutant. These results provide evidence that the pilin glycan stimulates a protective response that targets the O antigen, suggesting that this system could be used as the basis for the development of a variety of bioconjugate vaccines protective against gram-negative bacteria.
Growth and the plasma concentrations of growth hormone and prolactin in chicks: Effects of “environmental enrichment”, sex and strain (1980)

1. The effects of including novel objects in the environment ("environmental enrichment") on body-weight gain, relative body-weight gain, gain: food ratio, plasma growth hormone (GH) and prolactin concentrations in male and female broiler and layer chicks was investigated. 2. Environmental enrichment improved body-weight gain, relative body-weight gain and gain : food ratio but had no effect on circulating GH or prolactin concentrations. 3. Weight gain and gain : food ratio were greater in the broilers than in the layer chicks, while plasma GH and prolactin (females only) concentrations were less. 4. There were no sex differences in weight gain and relative weight gain but gain : food ratio was significantly greater in females than in males. In both strains plasma GH concentrations were higher in male than in female broilers.
Interaction between dengue virus fusion peptide and lipid bilayers depends on peptide clustering (2008)

Dengue fever is one of the most widespread tropical diseases in the world. The disease is caused by a virus member of the Flaviviridae family, a group of enveloped positive sense single-stranded RNA viruses. Dengue virus infection is mediated by virus glycoprotein E, which binds to the cell surface. After uptake by endocytosis, this protein induces the fusion between viral envelope and endosomal membrane at the acidic environment of the endosomal compartment. In this work, we evaluated by steady-state and time-resolved fluorescence spectroscopy the interaction between the peptide believed to be the dengue virus fusion peptide and large unilamellar vesicles, studying the extent of partition, fusion capacity and depth of insertion in membranes. The roles of the bilayer composition (neutral and anionic phospholipids), ionic strength and pH of the medium were also studied. Our results indicate that dengue virus fusion peptide has a high affinity to vesicles composed of anionic lipids and that the interaction is mainly electrostatic. Both partition coefficient and fusion index are enhanced by negatively charged phospholipids. The location determined by differential fluorescence quenching using lipophilic probes demonstrated that the peptide is in an intermediate depth in the hemilayers, in-between the bilayer core and its surface. Ultimately, these data provide novel insights on the interaction between dengue virus fusion peptide and its target membranes, namely, the role of oligomerization and specific types of membranes.
Temperature and Strain Measurements With Fiber Bragg Gratings Embedded in Stainless Steel 316 (2014)

Single-mode optical fibers with thin nickel coatings (outer diameter ~350 μm) are successfully embedded into stainless steel (SS) 316 components using bespoke laser-based additive manufacturing technology. In our approach, we manufacture SS 316 components using selective laser melting, incorporating U-shaped grooves with dimensions suitable to hold nickel-coated optical fibers. Coated optical fibers containing fiber Bragg gratings for strain monitoring and temperature sensing are placed in the groove. The embedding is completed by melting subsequent powder layers on top of the fibers. Cross-sectional microscopy analysis of the fabricated components, together with analysis of the Bragg gratings behavior during fabrication indicates a strong substance-to-substance bond between coated fiber and added SS 316 material. Temperature and strain cycling of the embedded sensors demonstrates the ability of gratings to survive the embedding process, and act as sensing elements in harsh environments. In situ strain and temperature measurements from within the component are demonstrated for high dynamic stress levels and elevated temperatures (<;400 °C).
On the Parameters of Human Visual Performance: An Investigation of the Benefits of Antialiasing (1987)

A two-part experiment was conducted to investigate the effects of aliasing artifacts and screen resolution on a simple visual recognition task. The results indicate that in many cases far less realism may be necessary in synthetic computer-generated imagery than is often assumed. The first part of the experiment was a subjective rating of image quality. The second part measured the relationship between image quality and task effectiveness: Subjects were asked to discriminate between images of two types of objects similar to objects used in experiments involving mental rotation. At higher resolutions, the elimination of aliasing artifacts did not significantly improve subjects' performances. At intermediate and low resolutions, comparable to what might be used for iconic menus, the reduction in aliasing artifacts improved performance. The subjective ratings indicate that for both high and low resolution the elimination of aliasing artifacts does not improve quality, whereas images rendered at intermediate resolutions are significantly degraded by aliasing artifacts to the extent that antialiasing improves the subjective rating. These results are interpreted in the context of an ongoing research program aimed at identifying the parameters of real-time human performance for graphics workstations.
Cost and Size Estimates for a Redox Bulk Energy Storage Concept (1977)

Preliminary capital cost and size estimates were made for an electrochemical bulk energy storage concept. The electrochemical system considered was an electrically rechargeable flow cell with a titanium trichloride |titanium tetrachloride ||ferric chloride|ferrous chloride redox couple. The preliminary calculations were made to help determine whether the redox‐flow‐cell system has an attractive potential as a bulk energy storage system for power load leveling. With the rise in demand for electric power, the problem facing the electric utility industry of meeting peak power demands has been growing more acute. Because present methods of meeting peak power demands are not entirely adequate the electric utility industry has been interested in new methods for meeting peak power demands. On the basis of preliminary capital cost estimates, size estimates, and several other important considerations, the redox‐flow‐cell system emerges as having great promise as a bulk energy storage system for power load leveling. The size of this system would be less than 2% of that of a comparable pumped hydroelectric plant. The capital cost of a 10 MW, 60 and 85 MW‐hr redox system is estimated to be $190–$330 per kilowatt. This cost compares well with that of competing systems, especially when one considers that for many sites a saving in transmission costs (up to $200 per kilowatt) could be realized with the redox system. This saving could be achieved because the redox systems could be built in various sizes and located near the load centers. The other important features of the redox system contributing to its load‐leveling application are its low adverse environmental impact, its high efficiency, its apparent absence of electrochemically related cycle life limitations, and its fast response.
Computed tomographic (CT) guided percutaneous fine-needle aspiration biopsy: the Yale experience. (1986)

Fifty-one CT-guided percutaneous fine-needle aspiration biopsies (PFNAB) were performed on 46 consecutive patients over 15 months. Cytologies were obtained to identify primary or secondary malignancy in the abdomen, pelvis, retroperitoneum, bone, and paraspinal region. Adequate cytologic material was obtained in 50 of 51 biopsies. There were 29 true-positive, 0 false-positive, 12 true-negative, and two false-negative cases with an overall accuracy rate of 95 percent. There was one minor complication, mesenteric hemorrhage, which did not require transfusion. Fifteen of the 51 biopsies were performed on outpatients. The procedure is an accurate, safe, and cost-effective nonsurgical means of diagnosing primary or secondary malignancy.

A new method for on wafer noise measurement (1993)

A method for measuring the noise parameters of MESFETs and HEMTs is presented. It is based on the fact that three independent noise parameters are sufficient to fully describe the device noise performance. It is shown that two noise parameters, R/sub n/ and mod Y/sub OPT/ mod , can be directly obtained from the frequency variation of the noise figure F/sub 50/ corresponding to a 50 Omega generator impedance. By using a theoretical relation between the intrinsic noise sources as additional data, the F/sub 50/ measurement only can provide the four noise parameters. A good agreement with more conventional techniques is obtained.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
