An Echo-Cancellation-Based 4800 Bit/s Full-Duplex DDD Modem (1984)

In this paper we describe an experimental 4800 bit/s fullduplex DDD modem which has been constructed at Bell Laboratories and AT&T Information Systems. The modem achieves full-duplex operation by using echo cancellation techniques. The main features of the modem's architecture and start-up procedure are discussed in the paper. We also study in detail the characteristics of an echo canceller structure which was found to be particularly attractive for this application. Finally, we present experimental performance results obtained over simulated channels in the laboratory and over telephone loopback facilities.
A Real-Time Haptic/Graphic Demonstration of how Error Augmentation can Enhance Learning (2006)

We developed a real-time controller for a 2 degree-of-freedom robotic system using xPC Target. This system was used to investigate how different methods of performance error feedback can lead to faster and more complete motor learning in individuals asked to compensate for a novel visuo-motor transformation (a 30 degree rotation). Four groups of human subjects were asked to reach with their unseen arm to visual targets surrounding a central starting location. A cursor tracking hand motion was provided during each reach. For one group of subjects, deviations from the “ideal” compensatory hand movement (i.e. trajectory errors) were amplified with a gain of 2 whereas another group was provided visual feedback with a gain of 3.1. Yet another group was provided cursor feedback wherein the cursor was rotated by an additional (constant) offset angle. We compared the rates at which the hand paths converged to the steady-state trajectories. Our results demonstrate that error-augmentation can improve the rate and extent of motor learning of visuomotor rotations in healthy subjects. Furthermore, our results suggest that both error amplification and offset-augmentation may facilitate neuro-rehabilitation strategies that restore function in brain injuries such as stroke.
Age of Moraines in Victoria Land, Antarctica (1962)

Abstract “Fresh-looking” moraines lying within a mile of glaciers in the lowlands of the McMurdo Sound area, Victoria Land, Antarctica have been interpreted by some to be only 50 or 100 yr. old and to have been left by recent glacier retreats. The present author believes that these moraines are considerably older because a comparison of the position of existing glacier fronts in the area with positions on photographs of 50 yr. ago shows no movement of the front or appreciable thickening or thinning of the glaciers during the last 50 yr. Radiocarbon dating of mummified seal carcasses lying near glacier fronts indicates that the glaciers have not been more extensive for at least 1,000 yr. The youngest moraines in the area are ice-cored moraines to the existing glaciers. Radiocarbon dates of algae from extinct ephemeral ponds in the ice-cored moraines indicate the moraines to be at least 6,000 yr. old. Additional evidence for the antiquity of the near-glacier moraines is the presence of a rather uniformly well-developed micro-relief pattern of sand-wedge polygons on both the end moraines and the ground moraines extending up to the existing glacier front. Studies show that it requires hundreds if not thousands of years for such well-developed polygonal patterns to form.
Structured Reduced Graphene Oxide/Polymer Composites for Ultra‐Efficient Electromagnetic Interference Shielding (2014)

A high‐performance electromagnetic interference shielding composite based on reduced graphene oxide (rGO) and polystyrene (PS) is realized via high‐pressure solid‐phase compression molding. Superior shielding effectiveness of 45.1 dB, the highest value among rGO based polymer composite, is achieved with only 3.47 vol% rGO loading owning to multi‐facet segregated architecture with rGO selectively located on the boundaries among PS multi‐facets. This special architecture not only provides many interfaces to absorb the electromagnetic waves, but also dramatically reduces the loading of rGO by confining the rGO at the interfaces. Moreover, the mechanical strength of the segregated composite is dramatically enhanced using high pressure at 350 MPa, overcoming the major disadvantage of the composite made by conventional‐pressure (5 MPa). The composite prepared by the higher pressure shows 94% and 40% increment in compressive strength and compressive modulus, respectively. These results demonstrate a promising method to fabricate an economical, robust, and highly efficient EMI shielding material.
The Assessment of Marine Gas Hydrates Through Electrical Remote Sounding: Hydrate Without a BSR? (2000)

Marine gas hydrates, prevalent in offshore sediments in Canada and Japan, are a possible hydrocarbon resource, a hazard to drilling and a source of a major greenhouse gas. Quantitative estimates of hydrate concentrations in deep sea sediment are difficult to obtain by conventional methods. We have sought novel techniques specifically designed for assessment such as transient electric dipole‐dipole electromagnetics. The latter method is based on the assumption of a reduced electrical conductivity in hydrate rich zones. Field trails of new apparatus on the Cascadia margin have proven successful. Excellent data were collected and analysed using a differential phase method to reduce systematic error. Apparent resistivities collected on three lines demonstrate that the resistivity of the seafloor is remarkably uniform over the whole survey area. The average hydrate concentration, deduced with the aid of a reference model based on the electrical logs of ODP holes 888 and 889, is about 17–26% of pore space (9–13% of sediment volume) in the 100 m interval above the BSR. The values are consistent with those obtained by other analyses. Further, the presence of hydrate is predicted in a region to the east of 889 B where there is no visible BSR.
Homogeneous and Heterogeneous Catalytic Reactions in Cobalt Oxide/Graphite Air Electrodes: I . Chemical Kinetics of Peroxide Decomposition by Co(II) Ions in Alkaline Solutions (1990)

This paper considers the role played by dissolved cobaltous ions in concentrated alkaline solutions in the homogeneous decomposition of and its significance to oxygen reduction in alkaline media. Dissolved cobaltous ions, in the form of in concentrated alkaline solutions, show a very high catalytic activity for the decomposition of even at a concentration of 1 ppm. The homogeneous decomposition of peroxide is not a simple first‐order reaction as reported in literature but is a 1.2 order reaction. It is suggested that kinetics of decomposition of in the presence of is controlled by the homogeneous catalytic reaction of the ions, the heterogeneous redox reaction between ions in solution, and the Co3+ ions in the cobalt oxide spinel lattice sites.
Topology control algorithms for rule-based routing (2010)

In this dissertation, we introduce a new topology control problem for rule-based link-state routing in autonomous networks. In this context, topology control is a mechanism to reduce the broadcast storm problem associated with link-state broadcasts. We focus on a class of topology control mechanisms called local-pruning mechanisms. Topology control by local pruning is an interesting multi-agent graph optimization problem, where every agent/router/station has access to only its local neighborhood information. Every agent selects a subset of its incident link-state information for broadcast. This constitutes the pruned link-state information (pruned graph) for routing. The objective for every agent is to select a minimal subset of the local link-state information while guaranteeing that the pruned graph preserves desired paths for routing. 
In topology control for rule-based link-state routing, the pruned link-state information must preserve desired paths that satisfy the rules of routing. The non-triviality in these problems arises from the fact that the pruning agents have access to only their local link-state information. Consequently, rules of routing must have some property, which allows specifying the global properties of the routes from the local properties of the graph. In this dissertation, we illustrate that rules described as algebraic path problem in idempotent semirings have these necessary properties.
The primary contribution of this dissertation is identifying a policy for pruning, which depends only on the local neighborhood, but guarantees that required global routing paths are preserved in the pruned graph. We show that for this local policy to ensure loop-free pruning, it is sufficient to have what is called an in atory arc composition property. To prove the sufficiency, we prove a version of Bellman's optimality principle that extends to path-sets and minimal elements of partially ordered sets.
As a motivating example, we present a stable path topology control mechanism, which ensures that the stable paths for routing are preserved after pruning. We show, using other examples, that the generic pruning works for many other rules of routing that are suitably described using idempotent semirings.
Eosinophilic esophagitis. Literature review (2015)

Mechanistic Study of the Effects of Agricultural Amendments on Photochemical Processes in Paddy Water during Rice Growth (2022)

The photochemical properties of paddy water might be affected by the commonly used amendments in rice fields owing to the associated changes in water chemistry; however, this important aspect has rarely been explored. We examined the effects of agricultural amendments on the photochemistry of paddy water during rice growth. The amendments significantly influenced the photogenerated reactive intermediates (RIs) in paddy water, such as triplet dissolved organic matter (<sup>3</sup>DOM*), singlet oxygen, and hydroxyl radicals. Compared with control experiments without amendments, the application of straw and lime increased the RI concentrations by up to 16.8 and 11.1 times, respectively, while biochar addition had limited effects on RI generation from paddy water in in situ experiments under sunlight. Fluorescence emission-excitation matrix spectroscopy, Fourier transform ion cyclotron resonance mass spectrometry, and structural equation modeling revealed that upon the addition of straw and lime amendments, humified DOM substances contained lignins, proteins, and fulvic acids, which could produce more RIs under irradiation. Moreover, the amendments significantly accelerated the degradation rate of 2,4-dichlorophenol but led to the <sup>3</sup>DOM*-mediated formation of more toxic and stable dimeric products. This study provides new insights into the effects of amendments on the photochemistry of paddy water and the pathways of abiotic degradation of organic contaminants in paddy fields.
Cross section measurement of e+e−→KS0KL0 at s=2.00−3.08  GeV (2021)

The cross sections of the process ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{K}_{S}^{0}{K}_{L}^{0}$ are measured at fifteen center-of-mass energies $\sqrt{s}$ from 2.00 to 3.08 GeV with a total integrated luminosity of $582\text{ }\text{ }{\mathrm{pb}}^{\ensuremath{-}1}$ and using the BESIII detector at the Beijing Electron Positron Collider. The results are found to be consistent with those obtained by BABAR. A resonant structure around 2.2 GeV is observed, with a mass and width of $2273.7\ifmmode\pm\else\textpm\fi{}5.7\ifmmode\pm\else\textpm\fi{}19.3\text{ }\text{ }\mathrm{MeV}/{c}^{2}$ and $86\ifmmode\pm\else\textpm\fi{}44\ifmmode\pm\else\textpm\fi{}51\text{ }\text{ }\mathrm{MeV}$, respectively, where the first uncertainties are statistical and the second ones are systematic. The product of its radiative width (${\mathrm{\ensuremath{\Gamma}}}_{{e}^{+}{e}^{\ensuremath{-}}}$) with its branching fraction to ${K}_{S}^{0}{K}_{L}^{0}$ ($B{r}_{{K}_{S}^{0}{K}_{L}^{0}}$) is $0.9\ifmmode\pm\else\textpm\fi{}0.6\ifmmode\pm\else\textpm\fi{}0.7\text{ }\text{ }\mathrm{eV}$.
[Serotonin transporter gene polymorphism in irritable bowel syndrome]. (2004)

The presence of STin2.12/10 genotype may be correlated with IBS. The presence of L/L genotype and 12/12-L/L genotype association in IBS patients carries an increased risk of C-IBS, whereas the presence of the L/S genotype carries an increased risk of D-IBS and A-IBS.
Vacuolar Transporters for Cadmium and Arsenic in Plants and their Applications in Phytoremediation and Crop Development (2018)

Soil contamination by heavy metals and metalloids such as cadmium (Cd) and arsenic (As) poses a major threat to the environment and to human health. Vacuolar sequestration is one of the main mechanisms by which plants control toxic materials including Cd and As. Understanding the mechanisms of heavy metal tolerance and accumulation can be useful for both phytoremediation and safe crop development. In this review, we summarize recent advances in deciphering the molecular mechanisms underlying vacuolar sequestration of Cd and As, and discuss potential biotechnological applications of this knowledge and efforts towards attaining these goals.
2P1-K01 A study on mechanism and control of bending and expanding Active Cord Mechanism : Slime model 1 (2007)

A snake-like robot is expected to be useful in disaster-relief and sewer-inspection by using its slender body and two degree-of-freedom joints. However a conventional snake-like robot has trouble meandering on uneven ground. In this research, we propose a bending and expanding joint unit of three degree-of-freedom. We develop new ACM-S1 (Active Cord Mechanism - Slime model 1) composed of a series of joints. Each joint of ACM-S1 has three flexible rods which are arranged in a circle at even intervals, fixed one end of each rod, and slid the other one. By this means, bending and expanding joint is realized. We examine the motion of practical ACM-S1 with waterproofing and dust-tight structure, and evaluate the performance of Inchworm motion.

High-temperature dynamic hohlraums on the pulsed power driver Z (1999)

In the concept of the dynamic hohlraum an imploding Z pinch is optically thick to its own radiation. Radiation may be trapped inside the pinch to give a radiation temperature inside the pinch greater than that outside the pinch. The radiation is typically produced by colliding an outer Z-pinch liner onto an inner liner. The collision generates a strongly radiating shock, and the radiation is trapped by the outer liner. As the implosion continues after the collision, the radiation temperature may continue to increase due to ongoing PdV (pressure times change in volume) work done by the implosion. In principal, the radiation temperature may increase to the point at which the outer liner burns through, becomes optically thin, and no longer traps the radiation. One application of the dynamic hohlraum is to drive an ICF (inertial confinement fusion) pellet with the trapped radiation field. Members of the dynamic hohlraum team at Sandia National Labs have used the pulsed power driver Z (20 MA, 100 ns) to create a dynamic hohlraum with temperature linearly ramping from 100 to 180 eV over 5 ns. On this shot zp214 a nested tungsten wire array of 4 and 2 cm diam with masses of 2 and 1 mg imploded onto a 2.5 mg plastic annulus at 5 mm diam. The current return can on this shot was slotted. It is likely the radiation temperature may be increased to over 200 eV by stabilizing the pinch with a solid current return can. A current return can with nine slots imprints nine filaments onto the imploding pinch. This degrades the optical trapping and the quality of the liner collision. A 1.6 mm diam capsule situated inside this dynamic hohlraum of zp214 would see 15 kJ of radiation impinging on its surface before the pinch itself collapses to a 1.6 mm diam. Dynamic hohlraum shots including pellets were scheduled to take place on Z in September of 1998.
Advanced energy management for home use (1989)

A novel system for controlling the electrical energy utilization in homes or small businesses is described. The developments include a telephone to power line carrier interface unit, a new electric meter that measures energy with variable pricing, and an energy controller that modifies use depending on price. The system provides for the marketing of electrical energy based on a supply/demand relationship using a real-time variable pricing scheme. A unique interface allows the customer to adjust energy utilization for heating or cooling, depending on comfort needs and the current price. Other electrical appliances such as electric water heaters can also be controlled automatically and optimally to achieve the lowest energy cost. A personal computer interface allows access to more detailed information and provides a means to personalize the system to a greater degree. The philosophy of this approach has been demonstrated, during field trials, to achieve the desired result of shifting some of the load from the peak to the valley. At the same time the users learned to use the system to lower their electric bills.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Evaluating the cost of software quality (1998)

The explosive growth of the software industry in recent years has focused attention on the problems long associated with software development: uncontrollable costs, missed schedules, and unpredictable quality. To remain competitive, software firms must deliver high quality products on time and within budget. However, to bring their products more quickly to market, software managers may avoid quality improvement processes such as design reviews and code inspections, believing that these processes only add time to the development cycle. Certainly the economics of improving quality are not well understood in the software development world
The hsp90-based Chaperone System: Involvement in Signal Transduction from a Variety of Hormone and Growth Factor Receptors (1998)

A variety of transcription factors and protein kinases involved in signal transduction are recovered from cells in heterocomplexes containing the abundant protein chaperone hsp90. Genetic studies in yeast have demonstrated that binding of steroid receptors, the dioxin receptor, and some protein kinases to hsp90 is critical for their signal transducing function in vivo. These heterocomplexes are formed by a multiprotein chaperone machinery consisting of at least four ubiquitous proteins--hsp90, hsp70, p60 and p23. Four high-molecular-weight immunophilins have been discovered as components of steroid receptor or other transcription factor complexes with hsp90. The immunophilins, protein chaperones with prolyl isomerase activity, bind the immunosuppressant drugs FK506 or CyP-40. These immunophilins all bind via tetratricopeptide repeat (TPR) domains to a single TPR binding site on each hsp90 dimer, and multiple heterocomplexes exist for each protein chaperoned by hsp90 according to the immunophilin that is bound to this TPR binding site at any time. Three components of the MAP kinase signalling system (Src, Raf, and Mek) exist in complexes with hsp90 and a 50-kDa protein that is the mammalian homolog of the yeast cell cycle control protein cdc37. The p50cdc37 binds to hsp90 at a site that is close to but different from the TPR binding site of the immunophilins, and like the immunophilins, p50cdc37 is thought to be involved in targeting and trafficking of the protein kinases. The recent introduction of the benzoquinone antibiotic geldanamycin has facilitated the identification of proteins that are chaperoned by the hsp90-based system. Geldanamycin binds to members of the hsp90 protein family, blocking assembly of hsp90 heterocomplexes and destabilizing preformed heterocomplexes. In the presence of geldanamycin, the function of hsp90-chaperoned proteins is disrupted, and the proteins undergo rapid degradation by an ubiquitin-dependent proteasomal mechanism. It is becoming clear that hsp90 chaperoning is not only essential to a variety of signal transduction pathways, but is critical for proper folding, stabilization, and trafficking of an expanding list of proteins.
