EMC analysis and prediction of complex electronic systems (1993)

Abstract A methodology is presented to study the interaction of electromagnetic disturbances with complex systems represented as networks of transmission lines. The systems are separated into distributed and lumped parts: a clear distinction is made between circuits of discrete lumped, linear, passive or active components that represent loads or interconnection blocks, and connecting wires that are treated as multi-conductor transmission lines. The telegrapher's differential equations represent a widely accepted model for wire bundles, buses or lines of common use in electrical and electronic circuitry. Coupling with external interfering disturbances is rigorously evaluated, and equivalent distributed sources are introduced along the lines. Each subsystem is viewed as a multi-port component and is characterized in terms of a multi-port matrix. This is a natural choice for the distributed element sections and it is also well suited for lumped circuits. The key element of this formulation is the definition of a correspondance matrix that accounts for the topology of the connections between sections and blocks. The solution of the system equations describes the influence of a disturbance in virtually any section of the network. The potential of this method to display either the frequency or the time response at different places inside a complex system is assessed.

Introduction to Anatomy and Neural Pathways (2005)

This review of the anatomy and neural pathways of motility has focused on the supranuclear pathways for eye movement, because these are the pathways that are responsible for misalignments that are often unfamiliar to the ophthalmologist. In these cases, the pattern of ocular misalignment does not seem to fit a cranial nerve palsy nor seem attributable to myasthenia gravis or orbital causes. When the motility pattern on exam does not seem to fit the distribution of the third, fourth, or sixth cranial nerve, myasthenia, or orbital causes, then supranuclear disorders of gaze should be considered. The most common supranuclear disorders encountered are internuclear ophthalmoplegia, skew deviation, dissociated vertical deviation (DVD), dorsal midbrain syndrome, and horizontal and vertical gaze palsies. The motility examination with prism measurements in different gaze positions in conjunction with neuroimaging usually points the diagnosis toward a supranuclear cause.
A digitalwaveguide model of the electric bass guitar including different playing techniques (2012)

In this paper, we present a novel audio synthesis model that allows us to simulate bass guitar tones with 11 different playing techniques to choose from. In contrast, previous approaches focussing on bass guitar synthesis only implemented the two slap techniques. We apply a digital waveguide model extended by different modular parts to imitate the sound production process on this instrument. The results of aMUSHRA listening test reveal that an audio coding scheme based on the presented algorithm offers a high perceived sound quality in comparison to conventional low bit-rate coding schemes while requiring a much lower bit-rate.

Lidar and DOAS remote sensing for pollution monitoring in the Washington, D.C., area during August/September 1992 (1994)

As a result of the development of a new air pollution measurement capability, we present observations of air pollution parameters in the Baltimore/Washington, D.C. area for the months of August and September 1992, requested by the Air and Radiation Management Administration, State of Maryland Department of the Environment (MDE). The measured parameters are (1) the height of the atmospheric boundary layer (BL) as determined by lidar (laser backscatter by aerosols) and (2) the concentration of the major gaseous pollutants (O<SUB>3</SUB>, SO<SUB>2</SUB>, and NO<SUB>2</SUB>) as determined by long-path differential optical absorption spectroscopy. Selected results are presented in pictorial, graphical, and tabular forms, and are compared with each other and with observations taken with other pollutant and meteorological instruments operating in the same region and time period. Complete data have been provided to the MDE for Urban Airshed Model calculations. Early results are promising on correlations between BL parameters and pollutant concentration; this relatively recent study is still underway.

Efficient finite element modeling of elastodynamic scattering with non-reflecting boundary conditions (2012)

An efficient technique for predicting the complete scattering behavior for an arbitrarily-shaped scatterer is presented. The spatial size of the modeling domain around the scatterer is as small as possible to minimize computational expense and a minimum number of models are executed. This model uses non-reflecting boundary conditions on the surface surrounding the scatterer which are non-local in space. Example results for 2D and 3D scattering in isotropic material and guided wave scattering are presented.
Enthalpic and Entropic Effects on Hydrogen and OH Adsorption on Pt(111), Pt(100), and Pt(110) Electrodes As Evaluated by Gibbs Thermodynamics (2010)

Gibbs thermodynamics have been used to characterize hydrogen and OH adsorption on Pt(111), Pt(100), and Pt(110) in 0.1 M HClO4. In this way, the Gibbs energy, enthalpy, and entropy of formation of the interface have been evaluated. The results demonstrate that hydrogen adsorption on the three platinum basal planes is mainly driven by entropic effects, while enthalpic effects are the driving force for OH adsorption. Remarkably, this thermodynamic analysis overcomes the limitations inherent to the more common treatment of data, employing a generalized isotherm. Nevertheless, the present work demonstrates that both approaches are adequate for the systems under study, and they provide complementary information. The relationships between the thermodynamic properties, obtained from both approaches, have been derived. Finally, the results are compared with experimental and theoretical data for hydrogen and OH adsorption on Pt(111), Pt(100), and Pt(110) under UHV conditions. It is found that the Pt−H bond energy is similar under electrochemical and UHV conditions, for the three basal planes, although the H−H lateral interactions seem to be more dependent on the environmental conditions. In the case of OH adsorption, it is concluded that coadsorbed water molecules play an important role on both the interaction of OH species with the platinum surface, and the OH−OH lateral interactions. This is related to the formation of hydrogen-bonds between neighboring water and OH species, and these bonds seem to be stronger for Pt(111) than for Pt(100).
Flexible bus: A self-restoring optical ADM ringarchitecture (1996)

A novel WDM optical network architecture based on a physical ring topology is proposed and demonstrated. The architecture does not require in-line channel filters, is immune to recirculating ASE noise and permits prompt traffic restoration in the event of fibre and node failures. The results obtained from a prototype network have been most encouraging.

Terahertz Signal Source and Receiver Operating Near 600 GHz and Their 3-D Imaging Application (2021)

In this article, a set of oscillators and a heterodyne image receiver operating near 600 GHz have been developed, each based on a 250-nm InP heterojunction bipolar transistor (HBT) technology and a 130-nm SiGe HBT technology, respectively. The oscillators are based on the common-base cross-coupled push-push topology, which employed coupled-line loads for improved output power and efficiency with a small area. The measured oscillation frequency ranges of the three oscillators with different coupled-line lengths were 628-682, 556-610, and 509-548 GHz, respectively, with a tuning capability achieved with bias variation. The maximum output power and the dc-to-RF efficiency achieved with the oscillators were -10 dBm and 0.19%, respectively. The heterodyne receiver, which consists of a mixer, an IF amplifier, and an IF detector, exhibited a maximum responsivity of 469 kV/W and a minimum noise equivalent power (NEP) of 0.64 pW/Hz <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1/2</sup> . A transmission-mode 3-D THz tomography imaging setup was established with one of the fabricated oscillators and the heterodyne receiver employed as the signal source and the image detector, respectively. With the imaging setup, a successful reconstruction of 3-D images of a target object was demonstrated based on the filtered back-projection algorithm.
Factors Related to Success or Failure of Second Renal Transplants (1976)

From January 1, 1968 to December 31, 1973, 50 patients received two or more kidney transplants. Patient and graft survival was highly dependent upon the source of the donor and to a lesser extent the functional duration of the first transplant and the elapsed time between first and second graft. Survival (patient and graft) was best in patients receiving two related grafts and worst in patients receiving two sequential cadaver grafts. Intermediate rates of success followed cadaver transplantation after rejection of a related graft. The highest failure rate was encountered when those patients who sustained an early loss of the first cadaver graft received a subsequent cadaver graft within a few months. We recommended removal of the acutely rejected graft and delay prior to retransplantation of patients who rapidly reject cadaver grafts in the face of maximal doses of immunosuppression. A delay will permit recovery from both the immunosuppression and any underlying subclinical infections, and will permit the recognition of anti-HL-A antibodies which may not be manifest soon after rejection. Retransplantation of the patient who is slowly rejecting the first kidney does not require prior removal of the rejected graft or delay in retransplantation.

Research on extending end data in empirical mode decomposition (2011)

In Empirical Mode Decomposition(EMD),to suppress the ending effect,extending the data near the two end points is used by mathematics fitting usually.In practice,extending the sampling-time can also extend the end points and suppress the ending effect.Comparison has been made among the data extending method between the mathematics fitting(the mirror extending method as example) and terminal intercept near the two end points.To test the effect of EMD,the correlation coefficient between the practical results and ideal results are calculated.As a result of simulation and numerical experiment(periodic harmonic function as example),it is shown that if the signal intercept around half the length of data signals,better results can be obtained than endpoint extending.More the interception of points approximates more ending effect can be effectively restrained.
Manipulation of hot carrier cooling dynamics in two-dimensional Dion–Jacobson hybrid perovskites via Rashba band splitting (2021)

Hot-carrier cooling processes of perovskite materials are typically described by a single parabolic band model that includes the effects of carrier-phonon scattering, hot phonon bottleneck, and Auger heating. However, little is known (if anything) about the cooling processes in which the spin-degenerate parabolic band splits into two spin-polarized bands, i.e., the Rashba band splitting effect. Here, we investigated the hot-carrier cooling processes for two slightly different compositions of two-dimensional Dion-Jacobson hybrid perovskites, namely, (3AMP)PbI<sub>4</sub> and (4AMP)PbI<sub>4</sub> (3AMP = 3-(aminomethyl)piperidinium; 4AMP = 4-(aminomethyl)piperidinium), using a combination of ultrafast transient absorption spectroscopy and first-principles calculations. In (4AMP)PbI<sub>4</sub>, upon Rashba band splitting, the spin-dependent scattering of hot electrons is responsible for accelerating hot-carrier cooling at longer delays. Importantly, the hot-carrier cooling of (4AMP)PbI<sub>4</sub> can be extended by manipulating the spin state of the hot carriers. Our findings suggest a new approach for prolonging hot-carrier cooling in hybrid perovskites, which is conducive to further improving the performance of hot-carrier-based optoelectronic and spintronic devices.
Dependence on Incident Angle of Solid State Detector Response to Gamma-Rays (2002)

The shape and size of a NaI (Tl) scintillator that should maximize response variation with γ-ray incident angle was estimated by analytical model calculation. It proved that, even for gamma rays of energy exceeding 1MeV, a slab detector measuring 50cm×50cm×5cm thick should present a ratio of at least 4 between maximum and minimum responses against incidence at different angles. For a sample case of 60keV gamma rays, estimation of the incident angle dependence by means of Monte Carlo simulation agreed well with experiment using a CZT detector. The counts from photoelectric peak varied with incident angle roughly along a sine curve. The foregoing finding served as basis for proposing a practical direction finder for γ-ray source operating on the principle of determining the source direction from variations in count with incident angle.
LIBERATION OF TARGET MATERIAL FROM LOCKED PARTICLES: A THEORETICAL ANALYSIS (1985)

ABSTRACT In the mineral processing industry most of the energy consumed by the plant is in the crushing and grinding operation used to liberate the target minerals from locked particles prior to their recovery. At present when it cornea to liberation, moat plants use a rule of thumb, since a sound fundamental analysis of locked particle comminution is lacking. Though much work has been done to represent comminution mathematically, most of the work has been devoted to single phase material. Eight theorems are presented to describe the behavior of competent locked particles during the size reduction process. The slope of the size distribution curve for the locked particles is found to be steep with repect to the size distribution of all the particles. These theorems demonstrate that mineral processing circuits may operate more economically by reducing grinding and employing better recovery circuits, and help in understanding, designing and justifying the use of new circuits.
Biallelic variants in ZNF142 lead to a syndromic neurodevelopmental disorder (2022)

Biallelic variants of the gene encoding for the zinc-finger protein 142 (ZNF142) have recently been associated with intellectual disability (ID), speech impairment, seizures, and movement disorders in nine individuals from five families. In this study, we obtained phenotype and genotype information of 26 further individuals from 16 families. Among the 27 different ZNF142 variants identified in the total of 35 individuals only four were missense. Missense variants may give a milder phenotype by changing the local structure of ZF motifs as suggested by protein modeling; but this correlation should be validated in larger cohorts and pathogenicity of the missense variants should be investigated with functional studies. Clinical features of the 35 individuals suggest that biallelic ZNF142 variants lead to a syndromic neurodevelopmental disorder with mild to moderate ID, varying degrees of delay in language and gross motor development, early onset seizures, hypotonia, behavioral features, movement disorders, and facial dysmorphism. The differences in symptom frequencies observed in the unpublished individuals compared to those of published, and recognition of previously underemphasized facial features are likely to be due to the small sizes of the previous cohorts, which underlines the importance of larger cohorts for the phenotype descriptions of rare genetic disorders.
A Study on Radical Fluxes in Silane Plasma CVD from Trench Coverage Analysis (1989)

The precursors of the a-Si:H film in SiH 4 plasma-enhanced CVD are investigated by use of trench coverage analysis. The cross sectional profile of deposited film in a trench is simulated by a direct Monte-Carlo method using the radical sticking probability β as an adjustable parameter. A comparison with the experimental results has shown that the trench coverage profiles are reproduced well by the model if two kinds of radicals, i.e., SiH 3 and SiH 2 , are deposited independently on the substrate with the respective sticking probabilities of 0.1 and 1.0. The experimentally observed dependence of the trench profile on the plasma condition can be explained by the change in the radical deposition ratio, which becomes SiH 3 /SiH 2 =1/1 in pure SiH 4 at low rf power and decreases to 1/2-1/3 in SiH 4 diluted in Ar at high rf power. The above change in the contribution of two kinds of radicals to the deposition is also supported by the chemical kinetic calculation of the gas phase reactions and the radical transport to the substrate.
Hydration of Aliphatic Nitriles Catalyzed by an Osmium Polyhydride: Evidence for an Alternative Mechanism (2021)

The hexahydride OsH<sub>6</sub>(P<sup>i</sup>Pr<sub>3</sub>)<sub>2</sub> competently catalyzes the hydration of aliphatic nitriles to amides. The main metal species under the catalytic conditions are the trihydride osmium(IV) amidate derivatives OsH<sub>3</sub>{κ<sup>2</sup>-<i>N</i>,<i>O</i>-[HNC(O)R]}(P<sup>i</sup>Pr<sub>3</sub>)<sub>2</sub>, which have been isolated and fully characterized for R = <sup>i</sup>Pr and <sup>t</sup>Bu. The rate of hydration is proportional to the concentrations of the catalyst precursor, nitrile, and water. When these experimental findings and density functional theory calculations are combined, the mechanism of catalysis has been established. Complexes OsH<sub>3</sub>{κ<sup>2</sup>-<i>N</i>,<i>O</i>-[HNC(O)R]}(P<sup>i</sup>Pr<sub>3</sub>)<sub>2</sub> dissociate the carbonyl group of the chelate to afford κ<sup>1</sup>-<i>N</i>-amidate derivatives, which coordinate the nitrile. The subsequent attack of an external water molecule to both the C(sp) atom of the nitrile and the N atom of the amidate affords the amide and regenerates the κ<sup>1</sup>-<i>N</i>-amidate catalysts. The attack is concerted and takes place through a cyclic six-membered transition state, which involves C<sub>nitrile</sub>···O-H···N<sub>amidate</sub> interactions. Before the attack, the free carbonyl group of the κ<sup>1</sup>-<i>N</i>-amidate ligand fixes the water molecule in the vicinity of the C(sp) atom of the nitrile.
Learning Reward Functions for Robotic Manipulation by Observing Humans (2023)

Observing a human demonstrator manipulate objects provides a rich, scalable and inexpensive source of data for learning robotic policies. However, transferring skills from human videos to a robotic manipulator poses several challenges, not least a difference in action and observation spaces. In this work, we use unlabeled videos of humans solving a wide range of manipulation tasks to learn a task-agnostic reward function for robotic manipulation policies. Thanks to the diversity of this training data, the learned reward function sufficiently generalizes to image observations from a previously unseen robot embodiment and environment to provide a meaningful prior for directed exploration in reinforcement learning. We propose two methods for scoring states relative to a goal image: through direct temporal regression, and through distances in an embedding space obtained with time-contrastive learning. By conditioning the function on a goal image, we are able to reuse one model across a variety of tasks. Unlike prior work on leveraging human videos to teach robots, our method, Human Offline Learned Distances (HOLD) requires neither a priori data from the robot environment, nor a set of task-specific human demonstrations, nor a predefined notion of correspondence across morphologies, yet it is able to accelerate training of several manipulation tasks on a simulated robot arm compared to using only a sparse reward obtained from task completion.
