Nucleation on substrates from the vapour phase

Abstract Recent developments in the theory of nucleation of vapour deposits on crystalline substrates are reviewed. To facilitate comparison, the theories are formulated in a common dimensionless notation, and an examination of the major underlying assumptions reveals the basic similarity of many of them. The capture and dissociation rates are expressed in terms of the cluster geometry and the pertinent energy parameters, and from these the ‘chemical’ rate equations are set up. The following types of approximate solutions are discussed: (a) long-time asymptotic solutions, from which the conditions for saturation in the cluster concentration may be deduced, (b) a generalization of the type of approximate solution used by Logan (1969), and (c) numerical solutions employing a minimum number of simplifying assumptions. Based on a simple model, agreement between the latter two seems reasonably good. For any given set of fixed parameters (energies, geometrical constants, and arrival rate from the vapour) severa.
Room-temperature visible and infrared photoluminescence from Pr-implanted GaN films by focused-ion-beam direct write

Visible and infrared photoluminescence (PL) have been obtained from Pr-implanted GaN films using focused-ion-beam (FIB) direct write utilizing a Pr–Pt liquid alloy ion source. FIB implantation was performed on GaN films grown by molecular-beam epitaxy (MBE), hydride vapor-phase epitaxy, and metalorganic chemical-vapor deposition. After annealing, strong room-temperature emission was observed in the red (at 650 nm) and in the infrared (at several wavelengths including 0.96, 1.3, and 1.9 μm). Essentially identical PL spectra were obtained in the implanted GaN films as in the in situ Pr-doped GaN films grown by MBE.
Quadratic stabilization of continuous time systems with state-delay and norm-bounded time-varying uncertainties

This paper develops a method for designing a feedback control law to stabilize a class of uncertain linear systems. The class of systems under consideration is described by a continuous-time model with variable-state delay and depends on time-varying unknown-but-bounded uncertain parameters. It is shown that the construction of the stabilizing controller involves solving a certain algebraic Riccati equation. Several previous results are derived as interesting special cases. Finally, a simulation example is presented to illustrate the analytical developments. >
One-Dimensional Shift of a Brownian Particle under the Feedback Control

In carrying a Brownian particle by means of an external force in one dimension from a place to another in a finite time lapse, we consider controlling the force using a feedback loop to minimize an evaluation functional. The evaluation functional contains the average of the work done to the particle by the force and two terms involving control parameters. One is a term proportional to the mean squared force, while the other is a term proportional to the mean squared distance between the final particle position and the destination. Solving differential equations numerically, we calculate the average work under optimal control for various values of control parameters and find the calculated values bounded from below. The average work is also shown to be larger as we utilize less information on the state of the particle in the feedback control by decreasing the number of observed variables and by increasing the noise amplitude in the observation.
Differential Calculi on Quantum Groupoids

The main aim of this article is to generalize results from Pflaum and Schauenburg (1997) to quantum groupoids (weak Hopf algebras). We first introduce the concept of a weak bicovariant differential calculus on quantum groupoids following some ideas of Woronowicz (1989). Then we establish such a noncommutative differential calculus on weak smash product over quantum groupoids in the sense of Nikshych (2000) and study the notion of a connection with respect to such differential calculus. Finally, we study the notion of a higher order differential calculus in an analogous concept for quantum groupoids in the sense of Schauenburg (1996).
Verification of Temporal Properties of Concurrent Systems

This thesis is concerned with the verification of concurrent systems modelled by process algebras. It provides methods and techniques for reasoning about temporal properties as described by assertions from an expressive modal logic -- the modal µ-calculus. It describes a compositional approach to model checking, efficient local and global algorithms for model checking finite-state systems, a general local fixed-point finding algorithm, a proof system for model checking infinite-state systems, a categorical completeness result for an intuitionistic version of the modal µ-calculus, and finally it shows some novel applications of the logic for expressing behavioural relations.
Topographicaily bound vortices

Abstract A variational principle is presented which characterises steady motions of inviscid, rotating, stratified fluids. This is used to construct nonlinear solutions corresponding to stationary cold-core and warm-core eddies above topography in a uniform stream. Numerical results are presented for the specific case of a right circular cylinder. The results show that below a critical free-stream velocity a circular, cold, anticyclonic eddy is present above the cylinder and a warm, cyclonic eddy with the same cross-sectional area is present to the right (looking downstream) of the cylinder.
Vortex manipulation in superconducting films with tunable magnetic topology

Using a combination of the phenomenological Ginzburg–Landau theory and micromagnetic simulations, we study properties of a superconducting film with an array of soft magnetic dots on top. An external in-plane magnetic field gradually drives the magnets from an out-of-plane or magnetic vortex state to an in-plane single-domain state, which changes spatially the distribution of the superconducting condensate. If induced by the magnets, the vortex–antivortex molecules exhibit rich transitions as a function of the applied in-plane field. At the same time, we show how the magnetic dots act as very effective dynamic pinning centers for vortices in an applied perpendicular magnetic field.
Feature Extraction for Kernel Minimum Squared Error by Sparsity Shrinkage

In this paper, a sparsity based model is proposed for feature selection in kernel minimum squared error (KMSE). By imposing a sparsity shrinkage term, we formulate the procedure of subset selection as an optimization problem. With the chosen small portion of training examples, the computational burden of feature extraction is largely alleviated. Experimental results conducted on several benchmark datasets indicate the effectivity and efficiency of our method.
Wintertime variability in the Euro‐Atlantic region in observations and in ECMWF seasonal ensemble experiments

An empirical orthogonal function (EOF) decomposition of monthly mean analyses of 500 hPa height (1949–94) is used to describe the interannual variability of the large‐scale flow in the Euro‐Atlantic region during winter. The first four EOFs resemble low‐frequency variability patterns identified in previous studies, such as the North Atlantic Oscillation, and the eastern Atlantic and Eurasian teleconnection patterns. The second EOF and fourth EOF (EOF4) are associated with the occurrence of El Niño‐like sea surface temperature (SST) anomalies according to an observational analysis; for EOF4, correlations with SST anomalies in the west Pacific are also important. Indications of an influence of tropical SST anomalies on the blocking‐like third EOF, emerging from the European Centre for Medium‐Range Weather Forecasts (ECMWF) re‐analysis (ERA) data, are not confirmed by a longer SST record. A negligible correlation exists between the first EOF and El Niño indices during the ERA period, although a link may be detected in earlier decades.
Seasonal Variation of Glucose Variability in Rather Elderly Patients with Type 2 Diabetes (T2D) Treated by Vildagliptin and Metformin (EquMet)

Background: Seasonal variation of HbA1c has been in focus. Patients and Methods: The protocol included type 2 diabetes (T2D) patients (n=26, 71.4±10.2 years) on vildagliptin and metformin (EquMet) and HbA1c changes in 4 seasons for 6 years. Results: HbA1c values ranged 6.9-7.5%, and tend to show highest in winter, and rather lower in autumn. Discussion & Conclusion: Rather elderly T2D cases can tolerate EquMet with fair control. Previous reports showed a similar tendency. Some factors may be involved in the variation, such as temperature, climate, carbohydrate intake, Ramadan, and others. Furthermore, blood pressure and cardiovascular disease (CVD) can also influence them.
Extended-shortwave infrared unipolar barrier detectors

The e-SWIR wavelength band is a performance gap for infrared detectors. At both shorter and longer wavelengths, high performance detector technologies exist: SWIR InGaAs detectors (1.7 micron cutoff), and MWIR (3-5 micron) detectors such as InAs-based and GaSb-based Unipolar Barriers, MCT, and InSb. This work discusses development of high performance e-SWIR detectors with cutoff wavelengths in the 2.7 - 2.8 micron range. Two approaches for e-SWIR detector absorber materials were evaluated, lengthening the wavelength response of the SWIR InGaAs technology and shortening the wavelength response of MWIR GaSb-based technology. The InGaAs e- SWIR approach employs mismatched InGaAs absorber layers on InP substrates, using graded AlInAs buffer layers. The GaSb-based approach uses lattice-matched InGaAsSb absorber layers on GaSb substrates. Additionally, two device architectures were examined, pn-based photodiodes and unipolar barrier photodiodes. For both of the absorber materials, the unipolar barrier device architecture was found to be superior. The unipolar barrier device architecture enables both types of device to be free of effects of surface leakage currents and generation-recombination dark currents. InGaAsSb-based devices show excellent performance, with diffusion-limited dark current within a factor of 2-4 of the HgCdTe standard, Rule 07. They achieve background-limited (BLIP) performance at T=210K, which is accessible by thermo-electric coolers. As expected, defects associated with latticemismatch increase dark currents of the InP-based approach. The dark currents of the mismatched unipolar barrier photodiodes are 30x larger than those of the lattice-matched GaSb approach, however despite the defects, the devices still exhibit diffusion-limited operation, and achieve BLIP operation at T=190K Further improvements in the InP-based approach are expected with refinements in the epitaxial structures. Both types of detector approaches are excellent alternatives to conventional e-SWIR detectors.
Interaction of oblique instability waves with a nonlinear plane wave

This paper is concerned with the downstream evolution of a resonant triad of initially non-interacting linear instability waves in a boundary layer with a weak adverse pressure gradient. The triad consists of a two-dimensional fundamental mode and a pair of equal-amplitude oblique modes that form a subharmonic standing wave in the spanwise direction. The growth rates are small and there is a well-defined common critical layer for these waves. As in Goldstein & Lee (1992), the wave interaction takes place entirely within this critical layer and is initially of the parametric-resonance type. This enhances the spatial growth rate of the subharmonic but does not affect that of the fundamental. However, in contrast to Goldstein & Lee (1992), the initial subharmonic amplitude is assumed to be small enough so that the fundamental can become nonlinear within its own critical layer before it is affected by the subharmonic. The subharmonic evolution is then dominated by the parametric-resonance effects and occurs on a much shorter streamwise scale than that of the fundamental. The subharmonic amplitude continues to increase during this parametric-resonance stage – even as the growth rate of the fundamental approaches zero – and the subharmonic eventually becomes large enough to influence the fundamental which causes both waves to evolve on the same shorter streamwise scale.
Block Coordinate Relaxation Methods for Nonparametric Wavelet Denoising

Abstract An important class of nonparametric signal processing methods entails forming a set of predictors from an overcomplete set of basis functions associated with a fast transform (e.g., wavelet packets). In these methods, the number of basis functions can far exceed the number of sample values in the signal, leading to an ill-posed prediction problem. The “basis pursuit” denoising method of Chen, Donoho, and Saunders regularizes the prediction problem by adding an l 1 penalty term on the coefficients for the basis functions. Use of an l 1 penalty instead of l 2 has significant benefits, including higher resolution of signals close in time/frequency and a more parsimonious representation. The l 1 penalty, however, poses a challenging optimization problem that was solved by Chen, Donoho and Saunders using a novel application of interior-point algorithms (IP). This article investigates an alternative optimization approach based on block coordinate relaxation (BCR) for sets of basis functions that are the finite union of sets of orthonormal basis functions (e.g., wavelet packets). We show that the BCR algorithm is globally convergent, and empirically, the BCR algorithm is faster than the IP algorithm for a variety of signal denoising problems.
Extended Scalp Reconstruction With a Free Supraclavicular Graft: A Case Report

Skin restoration after tumor excision, trauma, or burns may be achieved with full or split-thickness skin grafts or local flaps. The success rate of a skin graft depends on several independent factors. The supraclavicular region is considered a reliable donor site for head and neck skin defects because of its easy access. We present a case of a supraclavicular skin graft harvested to cover a skin deficit after the excision of a squamous cell carcinoma of the scalp. The postoperative course was uneventful regarding graft survival, the healing procedure, and the cosmetic outcome.
Adhesion energy in nanogap InP∕InGaAs microcantilevers

The adhesion energy is measured between InGaAs quantum wells that have collapsed across a 125nm air gap in an InP∕InGaAs heterostructure. The method relies on measuring the unadhered length and shape of collapsed microcantilevers with optical interferometry. The adhesion energy is found to be 72±16mJm−2. Since the air gap is much smaller than has been measured previously, the influence of van der Waals forces across the gap was included in theoretical modeling. It was found that the forces should not cause significant deviation from the standard adhesion models unless the adhesion energy drops below 25mJm−2.
Structure and optical properties of evaporated films of the Cr- and V-group metals

Thin films of Cr, Mo, and W rapidly evaporated in high vacuum (5×10−7 Torr) onto room‐temperature substrates show anomalously low reflectance (compared to bulk samples). From electron and x‐ray diffraction and electron microscopy, we find the normal bcc crystal structure, but with very fine grains. Columnar grains about 100 A in diameter were separated by a less dense grain‐boundary network about 10 A wide. The measured optical conductivity agrees with an inhomogeneous‐medium model that assumes the normal crystalline conductivity for the grain interiors, with model parameters that correlate to the observed columnar grain size. In contrast, V and Nb films rapidly evaporated onto room‐temperature substrates have the reflectance of bulk crystalline material. On liquid‐ nitrogen temperature substrates, however, V and Nb have normal bcc crystal structure but with small flat‐plate grains, and the same model, with appropriate parameters, accounts for the optical conductivity. The difference between these two gro.
Crystallinity, surface morphology, and magnetic properties of La0.7Sr0.3MnO3 thin films: An approach based on the laser ablation plume range models

We report on a systematic investigation of the influence of pulsed laser deposition (PLD) parameters upon the microstructure, surface morphology, and magnetic properties of La0.7Sr0. 3MnO3 (LSMO) thin films grown on (100) SrTiO3 substrates. The optimization of the physical properties requires a careful exploration of the main parameters such as the oxygen pressure P and the target-to-substrate distance D. We show that there is a strong correlation between both these parameters and an optimal distance (D=L0), which can be calculated from a PD3 scaling law (in accordance with a shock wave model). This particular value L0 corresponds to the distance for which all species are thermalized in the plume. In the D–P diagram, L0 defines two distinct regions for the morphology and the microstructure: (i) when D 1 μm) morphology. These films are perfectly epitaxial on the substrate, single-phase and not relaxed. (ii) When D≫L0, the films are colum.
The New Riddle of Radical Translation

This paper presents parts of a theory of radical translation with applications to the problem of construing reference. First, in sections 1 to 4 the general standpoint, inspired by Goodman's approach to induction, is set forth. Codification of sound translational practice replaces the aim of behavioral reduction of semantic notions. The need for a theory of translational projection (manual construction on the basis of a finite empirical correlation of sentences) is established by showing the anomalies otherwise resulting (e.g. from Quine's position). Then in section 5 a partial characterization of what constitutes an "admissible translation manual" is developed in the form of rules of translational projection governing correspondence of sentence-parts of a language-pair. Finally, in section 6, we give applications of the theory to the problem of construing reference. The general rules of section 5 suffice to rule out deviant referential schemes which have been held inscrutable alternatives to standard schemes.
Building Action Research Partnerships for Community Impact: Lessons From a National Community-Campus Engagement Project

While many studies have addressed the successes and challenges of participatory action research, few have documented how community campus engagement (CCE) works and how partnerships can be designed for strong community impact. This paper responds to increasing calls for ‘community first’ approaches to CCE. Our analysis draws on experiences and research from Community First: Impacts of Community Engagement (CFICE), a collaborative action research project that ran from 2012-2020 in Canada and aimed to better understand how community-campus partnerships might be designed and implemented to maximize the value for community-based organizations. As five of the project’s co-leads, we reflect on our experiences, drawing on research and practice in three of CFICE’s thematic hubs (food sovereignty, poverty reduction, and community environmental sustainability) to identify achievements and articulate preliminary lessons about how to build stronger and more meaningful relationships. We identify the need to: strive towards equitable and mutually beneficial partnerships; work with boundary spanners from both the academy and civil society to facilitate such relationships; be transparent and self-reflexive about power differentials; and look continuously for ways to mitigate inequities.
Efficient three‐dimensional Delaunay triangulation with automatic point creation and imposed boundary constraints

A method is described which constructs three-dimensional unstructured tetrahedral meshes using the Delaunay triangulation criterion. Several automatic point creation techniques will be highlighted and an algorithm will be presented which can ensure that, given an initial surface triangulation which bounds a domain, a valid boundary conforming assembly of tetrahedra will be produced. Statistics of measures of grid quality are presented for several grids. The efficiency of the proposed procedure reduces the computer time for the generation of realistic unstructured tetrahedral grids to the order of minutes on workstations of modest computational capabilities.
Down to Ten: Estimating the Effect of a Red Card in Soccer

Abstract We investigate the effect of the expulsion of a player on the outcome of a soccer match by means of a probability model for the score. We propose estimators of the expulsion effect that are independent of the relative strength of the teams. We use the estimates to illustrate the expulsion effect on the outcome of a match.
Mandatory Disclosures and Market Reaction: Evidence from Qatar Stock Exchange

Information disclosure, inter alia, has a tremendously increasing impact on the stock market. This study aims to investigate the reaction of stock market to the mandatory disclosures in Qatar Stock Exchange (QSE) for the period 2020-2022. To be precise, the paper investigates the market reaction as indicated by the trading volume and stock price change to disclosure of periodic financial reports (quarterly, semi-annual, and annual) and company news and, subordinately, the relationship between trade volume and stock price change of the 47 (±1) traded listed companies on the QSE for the period spans from January 2020 to October 2022. Trading volume, all market share index value and stock price change were descriptively analyzed, then investigated using a one-to-one period approach, pre and post disclosure. In consistency with a priori predictions, the result shows significant market reaction as indicated by the volatility of both trade volume and stock price change. Moderate evidence is given to support the market reaction to the periodic disclosure other than annual financial reports. Additionally, findings show a weak positive relationship between trade volume and stock price change. Interestingly, the investigation provides substantial support to the weak form market efficiency, at least for the widely traded stocks. This indicates that insiders are not being better informed about the company’s true value than outsiders in the QSE. Finally, results support to the widely held belief, but heretofore undocumented evidence from the region, that permanent disclosures provide information benefits to investors and, hence, greater benefit.
Organic nanoparticle (hyperbranched polymer)-dispersed photopolymers for volume holographic storage

We report on the use of hyperbranched polymers (HBPs) acting as mobile organic nanoparticles doped in methacrylate photopolymers for highly efficient volume holographic recording. Two types of reduced HBPs having the average size of 10nm are synthesized. The diffraction efficiency near 100% in the green (532nm) and substantive polymerization-shrinkage suppression in this photopolymer system are demonstrated. Periodic assembly of HBPs under holographic exposure is also observed.
