P‐type doping and devices based on ZnO (2004)

Abstract Both n‐type and p‐type ZnO will be required for development of homojunction light‐emitting diodes (LEDs) and laser diodes (LDs). It is easy to obtain strong n‐type ZnO, but very difficult to create consistent, reliable, high‐conductivity p‐type material. The most natural choice of an acceptor dopant is N, substituting for O, and indeed several groups have been able to obtain p‐type material by such doping. Surprisingly, however, other groups have also been successful with P and As, elements with much larger ionic radii than that of O. Although ZnO substrates are now available, most of the epitaxial p‐type layers so far have been grown on sapphire, or other poorly‐matched materials. The lowest p‐type resistivity obtained up to now is about 0.5 Ω‐cm, which should be sufficient for LED fabrication. In spite of the present availability of p‐type ZnO, very few homojunction LEDs have been reported so far, to our knowledge; however, several good heterojunction LEDs have been demonstrated, fabricated with p‐type layers composed of other materials. One such structure, with fairly strong 389‐nm emission at 300 K, involves n‐type ZnO and p‐type AlGaN, grown on an SiC substrate. Also, an N + ‐ion implanted ZnO layer, deposited by chemical vapor deposition on Al 2 O 3 , exhibits 388‐nm emission at 300 K and could be economical to produce. (© 2004 WILEY‐VCH Verlag GmbH & Co.

The scrambler attack: A robust physical layer attack on location privacy in vehicular networks (2015)

Vehicular networks provide the basis for a wide range of both safety and non-safety applications. One of the key challenges for wide acceptance is to which degree the drivers' privacy can be protected. The main technical privacy protection mechanism is the use of changing identifiers (from MAC to application layer), so called pseudonyms. The effectiveness of this approach, however, is clearly reduced if specific characteristics of the physical layer (e.g., in the transmitted signal) reveal the link between two messages with different pseudonyms. In this paper, we present such a fingerprinting technique: the scrambler attack. In contrast to other physical layer fingerprinting methods, it does not rely on potentially fragile features of the channel or the hardware, but exploits the transmitted scrambler state that each receiver has to derive in order to decode a packet, making this attack extremely robust. We show how the scrambler attack bypasses the privacy protection mechanism of state-of-the-art approaches and quantify the degradation of drivers' location privacy with an extensive simulation study. Based on our results, we identify additional technological requirements in order to enable privacy protection mechanisms on a large scale.
Convolutional Neural Network Architecture for Geometric Matching (2018)

We address the problem of determining correspondences between two images in agreement with a geometric model such as an affine, homography or thin-plate spline transformation, and estimating its parameters. The contributions of this work are three-fold. First, we propose a convolutional neural network architecture for geometric matching. The architecture is based on three main components that mimic the standard steps of feature extraction, matching and simultaneous inlier detection and model parameter estimation, while being trainable end-to-end. Second, we demonstrate that the network parameters can be trained from synthetically generated imagery without the need for manual annotation and that our matching layer significantly increases generalization capabilities to never seen before images. Finally, we show that the same model can perform both instance-level and category-level matching giving state-of-the-art results on the challenging PF, TSS and Caltech-101 datasets.
Risk for Permanent Pacemaker After Transcatheter Aortic Valve Implantation: A Comprehensive Analysis of the Literature (2011)

Patients undergoing TAVI with implantation of CVP are at significantly higher risk for development of AV block and subsequent need for permanent PM, particularly if RBBB preexists. Since AV block occurs in >90% within the first week after the procedure, careful monitoring should be performed for at least 7 days after TAVI.
Synthesis and Spectroscopic and Electrochemical Studies of Novel Benzo‐ or 2,3‐Naphtho‐Fused Tetraazachlorins, Bacteriochlorins, and Isobacteriochlorins (2003)

Benzene- or 2,3-naphthalene-ring-expanded tetraazachlorins (TACs), tetraazabacteriochlorins (TABCs), and tetraazaisobacteriochlorins (TAiBCs) have been synthesized by using tetramethylsuccinonitrile as a source of hydrogenated sites. The derived compounds were characterized by using NMR spectroscopy, X-ray crystallography, electronic and magnetic circular dichroism (MCD) spectroscopy, and electrochemical and spectroelectrochemical methods. X-ray analysis revealed that the benzene-fused TAiBC deviates slightly from planarity at the hydrogenated sites as a result of the presence of sp(3) carbons, which prefer a nonplanar tetrahedral conformation. The spectral data were analyzed by using a band deconvolution technique. In the electronic absorption spectra of TAC and TABC species, the Q band splits into two intense components and smaller splittings were observed for the 2,3-naphthalene-fused derivatives relative to the benzo-fused species. In contrast, in the case of TAiBCs, the Q band splitting was apparently not observed in absorption spectra, as expected from the C(2v) molecular symmetry. However, MCD signals of the Q band in TAiBCs showed Faraday B terms, implying that the accidental degeneracy of the LUMO and LUMO+1 was broken even for adjacently ring-fused species. Relative molecular orbital energies were estimated by using cyclic and differential pulse voltammetry. The first reduction potentials were close for TACs and TABCs, although those of TAiBCs shifted to more negative potentials. In contrast, although TABCs and TAiBCs exhibited similar first oxidation potentials, those of TACs appeared at more positive potentials. These properties were reproduced and rationalized by molecular orbital and configuration interaction calculations within the framework of the ZINDO/S Hamiltonian. DFT-level frequency calculations have succeeded in reproducing the IR spectra for low-symmetry tetraazaporphyrin (TAP) derivatives for the first time. The relationship between structures and spectral features is discussed.
Downlink Power Control for Multi-User VBR Video Streaming in Cellular Networks (2013)

We investigate the problem of downlink power control for streaming multiple variable bit rate (VBR) videos in a multicell wireless network, where downlink capacities are limited by inter-cell interference. We adopt a deterministic model for VBR video traffic that considers video frame sizes and playout buffers at the mobile users. The problem is to find the optimal transmit powers for the base stations, such that VBR video data can be delivered to mobile users without causing playout buffer underflow or overflow. We formulate a nonlinear nonconvex optimization problem and prove the condition for the existence of feasible solutions. A centralized branch-and-bound algorithm is then developed, which incorporates the Reformulation-Linearization Technique and can produce (1-ε)-optimal solutions. We also propose a low-complexity distributed algorithm with fast convergence as an alternative to the centralized algorithm. Through simulations with VBR video traces under fading channels, we find the distributed algorithm can achieve a performance very close to that of the centralized algorithm.
A Comprehensive Context for Mobile-Code Deployment (2005)

Given the acknowledged importance of mobile code, current distribution models are surprisingly primitive. For example, Java's model assumes that the constituent parts that make up a mobile program will all be downloaded to a single location, and then verified, linked, possibly dynamically compiled, and finally executed at that very location. This research project made three important contributions: First, it demonstrated that it can be beneficial to perform verification, dynamic compilation, and execution at different physical locations. A prototype was built that performs code verification and just-in-time compilation at a "code generating router" inside the network itself. If the end-points of the network are resource-limited devices such as wirelessly-connected personal digital assistants (PDA's), off-loading dynamic code generation to the stationary network can result in substantial benefits. As a second contribution, the project identified a novel attack on mobile code systems, based on the complexity of the code verification algorithm itself. The third contribution is a new mobile-code verification algorithm that not only lacks this vulnerability, but that is also more efficient.
The autophagy community (2012)

There are various definitions of community. A definition that I found in one of my dictionaries is the following: "A social, religious, occupational, or other group sharing common characteristics or interests and perceived or perceiving itself as distinct in some respect from the larger society within which it exists." Thus, I think it is fair to say that there is a worldwide autophagy community. That is, there is a group of researchers (our occupation), whose members share an interest in autophagy (our common characteristic), and that group is distinct from the larger society (I do not want to begin describing the many ways this applies). But do we feel like a community, and do we need a community? I suggest that a community is indeed beneficial, and I propose one mechanism for enhancing the development of the autophagy community.
Parameter Identification of Electrochemical Model for Vehicular Lithium-Ion Battery Based on Particle Swarm Optimization (2017)

The dynamic characteristics of power batteries directly affect the performance of electric vehicles, and the mathematical model is the basis for the design of a battery management system (BMS).Based on the electrode-averaged model of a lithium-ion battery, in view of the solid phase lithium-ion diffusion equation, the electrochemical model is simplified through the finite difference method. By analyzing the characteristics of the model and the type of parameters, the solid state diffusion kinetics are separated, and then the cascade parameter identifications are implemented with Particle Swarm Optimization. Eventually, the validity of the electrochemical model and the accuracy of model parameters are verified through 0.2–2 C multi-rates battery discharge tests of cell and road simulation tests of a micro pure electric vehicle under New European Driving Cycle (NEDC) conditions. The results show that the estimated parameters can guarantee the output accuracy. In the test of cell, the voltage deviation of discharge is generally less than 0.1 V except the end; in road simulation test, the output is close to the actual value at low speed with the error around ±0.03 V, and at high speed around ±0.08 V.
T cell-independent and T cell-dependent B cell activation increases IFN- <i>gamma</i> R expression and renders B cells sensitive to IFN- <i>gamma</i> -mediated inhibition. (1994)

We have studied the relationship between B cell activation and the ability of IFN-gamma to inhibit B cell differentiation. The LPS activation of conventional and CD5+ B cells resulted in increased IFN-gamma R expression and increased the ability of IFN-gamma to inhibit LPS-induced B cell differentiation correlated with increased IFN-gamma R expression. We detected increased B cell IFN-gamma R expression 12 h after activation, and maximal IFN-gamma R expression was observed at 24 h. Activation of B cells by F(ab2)' anti-IgM induced a similar increase in IFN-gamma R expression. In autoimmune New Zealand Black mice, both conventional and CD5+ B cells showed a pattern of IFN-gamma R expression similar to that seen in DBA/2 mice, and both populations of B cells were sensitive to inhibition by IFN-gamma. To examine the role of IFN-gamma in the regulation of T cell-dependent B cell responses, we activated B cells with the CDC35 T cell line (which is specific for rabbit IgG). When rabbit anti-mouse Ig-treated B cells were activated by CDC35 T cells, we found that B cells exhibited increased IFN-gamma R expression by 48 h; we also found that IFN-gamma inhibited CDC35-mediated IgM secretion to a degree similar to IFN-gamma inhibition of T cell-independent B cell differentiation. Additionally, IFN-gamma inhibited CDC35-stimulated B cells even in the presence of exogenous IL-4 and IL-5. This study establishes the importance of IFN-gamma as a regulator of both T cell-independent and T cell-dependent B cell differentiation.

Photoionization of As2 and As4: Implications for group V clusters (1992)

The vacuum ultraviolet photoionization mass spectrum of As4 is presented, from the ionization threshold to 600 Å. The apparent adiabatic ionization potential is ≤8.49 eV, but the true value may be significantly lower. Three broad autoionization features are observed, probably comprising members of a Rydberg series converging to the B̃ 2A1 state of As+4. The first fragment, As+3, has an appearance potential (0 K) of 11.23±0.05 eV, from which we extract ΔH0f0(As+3)≤228.7±1.3 kcal/mol. The photoion yield curve of As+2(As2) is obtained under conditions where As2 is dominant in the vapor. The adiabatic ionization potential is 9.69±0.02 eV. Two prominent autoionizing Rydberg series are observed, converging to the A 2Σ+g state of As+2, with an ionization potential of 10.238±0.002 eV. At higher energy, three members of a window resonance series can be seen, converging to the B 2Σ+u state of As+2, with an ionization potential of 15.37 eV. From an upper limit to the partial pressure of As3, equilibrium conditions, and assuming a triangular As3, we deduce ΔH0f0(As3)≥60.0 kcal/mol; other criteria suggest ΔH0f0(As3)≂63 kcal/mol. Consequently, the adiabatic ionization potential of As3 is &lt;7.32 eV, and probably ≤7.19 eV. Several implications are drawn, relevant to recent studies of antimony and bismuth clusters.

Efficient Transistor-Level Sizing Technique under Temporal Performance Degradation due to NBTI (2006)

Temporal performance degradation in VLSI circuits due to Negative Bias Temperature Instability (NBTI) has emerged as a challenging design issue in nano-scale technology. In this paper, we analyze the impact of NBTI degradation in circuit performance in terms of timing, and show that under worst case scenario, one can expect more than a 10% degradation in the maximum circuit delay after 3 years (~ 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">8</sup> seconds) operation time. Based on this observation, we propose an efficient transistor-level sizing algorithm based on a modified Lagrangian Relaxation (LR) technique to account for the temporal degradation of circuit and guarantee lifetime reliability of circuit under NBTI. The technique reformulates the sizing problem by considering the fact that only the rising (0 → 1) delays of CMOS logic gates are affected by the NBTI. Experimental results on several ISCAS'85 benchmarks have shown that our proposed transistor-level sizing approach can reduce the area overhead of conventional cell-level sizing method by an average of 43%.
Simultaneous dual-wavelength-band common-path swept-source optical coherence tomography with single polygon mirror scanner (2011)

We report a novel (to the best of our knowledge) simultaneous 1310/1550 two-wavelength band swept laser source and dual-band common-path swept-source optical coherence tomography (SS-OCT). Synchronized dual-wavelength tuning is performed by using two laser cavities and narrowband wavelength filters with a single dual-window polygonal scanner. Measured average output powers of 60 and 27 mW have been achieved for the 1310 and 1550 nm bands, respectively, while the two wavelengths were swept simultaneously from 1227 to 1387 nm for the 1310 nm band and from 1519 to 1581 nm for the 1550 nm band at an A-scan rate of 65 kHz. Broadband wavelength-division multiplexing is used for coupling two wavelengths into a common-path single-mode GRIN-lensed fiber probe to form dual-band common-path SS-OCT. Simultaneous OCT imaging at 1310 and 1550 nm is achieved. This technique allows for in vivo high-speed OCT imaging with potential application in functional (spectroscopic) investigations.
State of the Art of Compactness and Circularity Measures 1 (2009)

Compactness is an intrinsic property of objects. This feature is often associated with the old and classical ratio perimeter2/area. This ra-tio is used in many scientific fields as shape descriptor in shape analysis tasks. However, when we use this ratio for measuring shape compactness in the digital domain some problems arise. Several approaches have been proposed for measuring shape compactness of discrete regions. This pa-per presents a review of several methods for measuring shape circularity and compactness and surveys some of them when scaling transforma-tion is applied to discrete regions. Also, we present a comparison of the studied methods using the same set of examples of binary shapes under different conditions: shapes with holes and with noisy perimeters.

Effect of Aminoethoxyvinylglycine (AVG) on Preharvest Drop, Fruit Quality, and Maturation of `McIntosh' Apples. II. Effect of Timing and Concentration Relationships and Spray Volume (2004)

AVG was evaluated for its effect on controlling preharvest drop and influencing ripening of `McIntosh' apples in Maine and Massachusetts. AVG consistently and effectively retarded preharvest drop. AVG was superior to NAA and comparable to daminozide in drop control. Dilute or 2× applications were more effective than applications made at lower water volumes. One application of AVG made 4 weeks before anticipated normal harvest was more effective in controlling preharvest drop than split applications of the same amount made earlier or later. In general, AVG delayed ripening as assessed by a retardation in the development of red color, maintenance of flesh firmness, delayed degradation of starch, and a delayed onset of the ethylene climacteric. We conclude that AVG is an effective drop control compound that is also useful as a management tool to extend the harvest window for blocks of `McIntosh' that would otherwise ripen simultaneously. Chemical names used: aminoethoxyvinylglycine (AVG), naphthaleneacetic acid (NAA), succinic acid-2,2-dimethylhydrazide (daminozide, Alar).

To know slowly (2018)

This two-part essay offers a personal reflection on an emerging Feldenkrais-informed practice in dance performance and pedagogy. As a post-positivist piece of writing from practice, the essay acknowledges the first-hand experience of the researcher as documenter of embodied process. The essay makes reference to the research of Sylvie Fortin and Warren Long (2000) who explore the potential of Feldenkrais learning for the dancer. The writing of Moshe Feldenkrais (2010, 1990), Norman Doidge (2015) and Guy Claxton (2016, 1997) illustrate notions of organic learning and knowing slowly.
In Part 1 of the essay I reflect upon the impact of the Feldenkrais Method on my dancing. I highlight how the Feldenkrais Method offered me the opportunity to get to know the difference between the dancer that moves and the dancer that knows they are moving. Part 2 directs the reflection towards the experience of students I have been teaching at the University of Chichester, introducing an emerging practice, Awareness in Motion (AIM)​.
