description: The properties of a dilute granular gas in the homogeneous cooling state are mapped to those of a stationary state by means of a change in the time scale that does not involve any internal property of the system. The new representation is closely related with a general property of the granular temperature in the long time limit. The physical and practical implications of the mapping are discussed. In particular, simulation results obtained by the direct simulation Monte Carlo method applied to the scaled dynamics are reported. This includes ensemble averages and also the velocity autocorrelation function, as well as the self-diffusion coefficient obtained from the latter by means of the Green-Kubo representation. In all cases, the obtained results are compared with theoretical predictions.

description: Discovered by William Chapple in 1746, the Poristic family is a set of variable-perimeter triangles with common Incircle and Circumcircle. By definition, the family has constant Inradius-to-Circumradius ratio. Interestingly, this invariance also holds for the family of 3-periodics in the Elliptic Billiard, though here Inradius and Circumradius are variable and perimeters are constant. Indeed, we show one family is mapped onto the other via a varying similarity transform. This implies that any scale-free quantities and invariants observed in one family must hold on the other.

description: This research investigates the effect of outdoor lounges with campfires and fountains on university campuses on students' belonging and social connection. We hypothesized that the outdoor lounge with a fire pit and water feature would increase students’ belonging and social connection compared with a lounge without any special feature. Through a between-subjects experimental design, we randomly assigned 159 university students to one of three conditions, where they were shown an image of an outdoor lounge and asked to complete a standardized survey measuring belonging and social connection. The results showed that the three conditions have similar scores on both PSSM and SCS scales. Therefore, no significant difference has been shown in students' levels of belonging and social connection among the three conditions. Our hypothesis was not supported. Despite limitations such as small sample size and the use of images rather than in-person experience, our findings suggest that the type of outdoor lounge on a university campus may not significantly impact students' sense of belonging and social connection.

description: We investigate the performance of a quantum error-correcting code when pushed beyond its intended capacity to protect information against errors, presenting formulae for the probability of failure when the errors affect more qudits than that specified by the code's minimum distance. Such formulae provide a means to rank different codes of the same minimum distance. We consider both error detection and error correction, treating explicit examples in the case of stabilizer codes constructed from qubits and encoding a single qubit.

description: Nonreciprocity has been introduced to various fields to realize asymmetric, nonlinear, and/or time non-revisal physical systems. By virtue of the Maxwell-Betti reciprocal theorem, breaking the time-reversal symmetry of dynamic mechanical systems is only possible using nonlinear materials. Nonetheless, nonlinear materials should be accompanied by geometrical asymmetries to achieve nonreciprocity in static systems. Here, we further investigate this and demonstrate a novel nonreciprocal elasticity concept. We show that the nonreciprocity of static mechanical systems can be achieved only and only if the material exhibits nonreciprocal elasticity. We experimentally demonstrate linear and nonlinear materials with nonreciprocal elasticities. By means of topological mechanics, we demonstrate that the mechanical nonreciprocity requires nonreciprocal elasticity no matter what the material is linear or nonlinear elastic. We show that linear materials with nonreciprocal elasticity can realize nonreciprocal-topological systems. The nonreciprocal elasticity developed here will open new venues of the design of mechanical systems with effective nonreciprocity.

description: Depth data has a widespread use since the popularity of high-resolution 3D sensors. In multi-view sequences, depth information is used to supplement the color data of each view. This article proposes a joint encoding of multiple depth maps with a unique representation. Color and depth images of each view are segmented independently and combined in an optimal Rate-Distortion fashion. The resulting partitions are projected to a reference view where a coherent hierarchy for the multiple views is built. A Rate-Distortionoptimization is applied to obtain the final segmentation choosing nodes of the hierarchy. The consistent segmentation is used to robustly encode depth maps of multiple views obtaining competitive results with HEVC coding standards.

description: How does an audio stimulus impact one’s perceived temperature and stress levels? Researchers predict two potential outcomes where an audio stimulus that elicits heat will increase one’s perceived temperature while decreasing stress levels. The second hypothesis states that an audio stimulus that evokes cooling sensations will decrease both perceived temperature and stress levels within a person. Through the use of a between-subjects design each participant (n = 251) is randomly assigned to one of three conditions: a fireplace or waterstream condition, as experimental groups, and a white noise condition being the control group. By administering a pre and post-test survey to all participants, researchers can measure the difference in temperature and stress levels through self-reported evaluations. An ANOVA test affirms both hypotheses as correct and suggests that an audio stimulus has the capability to increase or decrease both perceived temperature and stress levels.

description: A weak-coupling formalism for superconducting states possessing both singlet (even parity) and triplet (odd parity) components of the order parameter in centrosymmetric crystals is developed. It is shown that the quasiparticle energy spectrum may be non-degenerate even if the triplet component is unitary. The superconducting gap of a mixed-parity state may have line nodes in the strong spin-orbit coupling limit. The pseudospin carried by the superconducting electrons is calculated, from which follows a prediction of a kink anomaly in the temperature dependence of muon spin relaxation rate. The anomaly occurs at the phase boundary between the bare triplet and mixed-parity states. The stability of mixed-parity states is discussed within Ginzburg-Landau theory. The results may have immediate application to the superconducting series Pr(Os,Ru)4Sb12.

description: Les 30 dernières années ont été marquées par un vaste mouvement de libéralisation des échanges des produits agricoles, qui a fortement impacté les filières agricoles européennes et contraint l’Europe à adopter des réformes de la politique agricole commune. De nombreux travaux de recherches conduits dans le département des sciences sociales à l’INRA ont évalué les conséquences et les efficacités économiques et environnementales de ces accords et réformes ainsi que leur compatibilité. Plus récemment, les causes et conséquences des volatilités sur les marchés agricoles mondiaux ont motivé de nouvelles recherches, conduites avec des outils d’analyse toujours plus riches. Nous assistons depuis quelques années à un mouvement plus protectionniste. Inévitablement, les sciences économiques seront questionnées sur les conséquences et pertinences de ces récentes décisions. Les cadres d’analyse devront à l’avenir encore s’enrichir pour éclairer des débats publics toujours plus complexes.

description: Kinetic equations for the stationary state distribution function of ions moving through narrow pores are solved for a number of one-dimensional models of single ion transport. Ions move through pores of length $L$, under the action of a constant external field and of a concentration gradient. The interaction of single ions with the confining pore surface and with water molecules inside the pore are modelled by a Fokker-Planck term in the kinetic equation, or by uncorrelated collisions with thermalizing centres distributed along the pore. The temporary binding of ions to polar residues lining the pore is modelled by stopping traps or energy barriers. Analytic expressions for the stationary ion current through the pore are derived for several versions of the model, as functions of key physical parameters. In all cases, saturation of the current at high fields is predicted. Such simple models, for which results are analytic, may prove useful in the study of the current/voltage relations of ion channels through membranes.

description: We demonstrate that the effective Hamiltonians obtained with the downfolding procedure based on double unitary coupled cluster (DUCC) ansatz can be used in the context of Greens function coupled cluster (GFCC) formalism to calculate spectral functions of molecular systems. This combined approach (DUCC-GFCC) provides a significant reduction of numerical effort and good agreement with the corresponding all-orbital GFCC methods in energy windows that are consistent with the choice of active space. These features are demonstrated on the example of two benchmark systems: H2O and N2, where DUCC-GFCC calculations were performed for active spaces of various sizes.

Creators: name: Soin, Simal
Publisher: name: The Open University
Year: 2001

description: A side-effect of immunosuppression following renal transplantation is the development of skin infections and non-melanoma skin cancers which are associated with human papillomavirus (HPV) infection and sun exposure. Heart-lung transplant recipients are on average younger than renal allograft recipients and also receive a higher level of immunosuppressive therapy. To ascertain the incidence of HPV-associated cutaneous complications after heart and lung transplantation and the role of potential risk factors, we have investigated 397 of the surviving transplant recipients by means of questionnaire, review of medical records, and a proportion by interview and examination.
A high incidence of warts and non-melanoma skin cancers was found in heart-lung and heart transplant population studied in accordance with previous studies on renal transplant recipients. These skin complications of immunosuppression, especially warts, keratoses and cancers, were present in 249 patients (62.7%). Skin cancer was present in 17.6% of transplant recipients, all of whom were 5 or more years post-transplant. The squamousibasal cell carcinoma ratio was 8:1. HPV DNA was detected in 13 of 31 SCC samples analysed. In 6 cases, the HPV was HPV 20. 86% of the patients with skin cancers had high levels of lifetime occupational or social sun exposure.
Sun exposure, male gender and increasing graft survival time have emerged as major risk factors with minor influences from age and level of immunosuppression. No HI_A associations were found in the patients with malignancy in contrast to observations in kidney transplant patients.
Warts were found in 33.8% of patients, with a significantly higher incidence in males than in females, but were not influenced by levels of sun exposure.

description: Scene text recognition in low-resource Indian languages is challenging because of complexities like multiple scripts, fonts, text size, and orientations. In this work, we investigate the power of transfer learning for all the layers of deep scene text recognition networks from English to two common Indian languages. We perform experiments on the conventional CRNN model and STAR-Net to ensure generalisability. To study the effect of change in different scripts, we initially run our experiments on synthetic word images rendered using Unicode fonts. We show that the transfer of English models to simple synthetic datasets of Indian languages is not practical. Instead, we propose to apply transfer learning techniques among Indian languages due to similarity in their n-gram distributions and visual features like the vowels and conjunct characters. We then study the transfer learning among six Indian languages with varying complexities in fonts and word length statistics. We also demonstrate that the learned features of the models transferred from other Indian languages are visually closer (and sometimes even better) to the individual model features than those transferred from English. We finally set new benchmarks for scene-text recognition on Hindi, Telugu, and Malayalam datasets from IIIT-ILST and Bangla dataset from MLT-17 by achieving 6%, 5%, 2%, and 23% gains in Word Recognition Rates (WRRs) compared to previous works. We further improve the MLT-17 Bangla results by plugging in a novel correction BiLSTM into our model. We additionally release a dataset of around 440 scene images containing 500 Gujarati and 2535 Tamil words. WRRs improve over the baselines by 8%, 4%, 5%, and 3% on the MLT-19 Hindi and Bangla datasets and the Gujarati and Tamil datasets.

description: A current problem in the design of small and lightweight autonomous agricultural robots is how to create sufficient traction on soil to pull an agricultural implement or load. One promising solution is offered by the interlock drive system, which penetrates spikes into the soil to create traction. The combination of soil penetrating spikes and a push-pull design offers new possibilities for vehicle control. By controlling the interlocking of the spikes and pushing and pulling them against the main frame, the vehicle can perform tight maneuvers. To validate this idea, we designed a robot, capable of creating high traction and performing headland turns. The navigation of the new robot system is performed by actively pushing the spikes, mounted on a slide into the soil, while the main frame is pushed back and pulled forward. The vehicle of 2-meter length was able to turn on the spot, and could follow a straight line, just using the spikes and the push-pull mechanism. The trajectory and the performed measurements suggest, that a vehicle which uses only spikes for traction and steering is fully capable of performing autonomous tasks in agriculture fields.

description: Scene-text recognition is remarkably better in Latin languages than the non-Latin languages due to several factors like multiple fonts, simplistic vocabulary statistics, updated data generation tools, and writing systems. This paper examines the possible reasons for low accuracy by comparing English datasets with non-Latin languages. We compare various features like the size (width and height) of the word images and word length statistics. Over the last decade, generating synthetic datasets with powerful deep learning techniques has tremendously improved scene-text recognition. Several controlled experiments are performed on English, by varying the number of (i) fonts to create the synthetic data and (ii) created word images. We discover that these factors are critical for the scene-text recognition systems. The English synthetic datasets utilize over 1400 fonts while Arabic and other non-Latin datasets utilize less than 100 fonts for data generation. Since some of these languages are a part of different regions, we garner additional fonts through a region-based search to improve the scene-text recognition models in Arabic and Devanagari. We improve the Word Recognition Rates (WRRs) on Arabic MLT-17 and MLT-19 datasets by 24.54% and 2.32% compared to previous works or baselines. We achieve WRR gains of 7.88% and 3.72% for IIIT-ILST and MLT-19 Devanagari datasets.

title: Interaction of RGG and HTH motifs with nucleic acids: a study with rationally designed synthetic and recombinant polypeptides
Creators: name: Guarnaccia, Corrado
Publisher: name: The Open University
Year: 2001

description: The aim of this work is to provide data on the weak interactions between proteins and nucleic acids, using a sequence-specific DNA-binding protein (the recombinant 1-69 N-terminal domain of the phage 434 cl repressor, R69), and a non-specific nucleic acid binding domain (the arginine rich RGG domain of human nucleolin produced by solid phase synthesis) as in vitro model systems.

Pyrene fluorescence spectroscopy and disulfide crosslinking via C-terminally attached Cys residues showed that cognate DNA acts as template for R69 dimerization even in the absence of the native C-terminal dimerization domain. Dimeric binding of R69 to DNA results in intensive pyrene excimer fluorescence resulting from the stacking of two C-terminally attached pyrene labels. The'fluorescence of the pyrene monomer (383nm) is quenched in a salt/sensitive manner by both cognate and non-cognate DNA molecules, probably due to electrostatic interactions with the DNA backbone. DNA sequences as short as the half-site are sufficient to promote dimer formation in a detectable manner. On the other hand, studies with artificial hybrid operators prove that two half sites provide complete specificity to the complex assembly. These studies suggest that sequential binding of monomers is a plausible pathway for the assembly of R69 on DNA.

The RGG motif is present in many specific and non-specific nucleic acid binding proteins and its arginine residues undergo methylation by protein arginine methyltransferase type I as a part of various, not entirely known regulatory events. We used novel methods of solid phase peptide synthesis to produce methylated and non-methylated peptides spanning sequences from residues 646-706 of the human nucleolin C-terminal domain and we used them to study nucleic acid binding in vitro.

 Melting curve assays, double filter binding assays and circular dichroism studies showed that the non-sequence specific nucleic acid binding is sensitive to the geometry of the nucleic acid as it binds ssDNA>RNA>dsDNA. While binding strength is not substantially influenced by dimethylation, the ability of the peptides to modify the nuclecic acid structure, detected by CD spectroscopy, is substantially decreased upon methylation.

description: Many challenges faced in today's semiconductor devices are related to self-heating phenomena. The optimization of device designs can be assisted by numerical simulations using the non-isothermal drift-diffusion system, where the magnitude of the thermoelectric cross effects is controlled by the Seebeck coefficient. We show that the model equations take a remarkably simple form when assuming the so-called Kelvin formula for the Seebeck coefficient. The corresponding heat generation rate involves exactly the three classically known self-heating effects, namely Joule, recombination and Thomson-Peltier heating, without any further (transient) contributions. Moreover, the thermal driving force in the electrical current density expressions can be entirely absorbed in the diffusion coefficient via a generalized Einstein relation. The efficient numerical simulation relies on an accurate and robust discretization technique for the fluxes (finite volume Scharfetter-Gummel method), which allows to cope with the typically stiff solutions of the semiconductor device equations. We derive two non-isothermal generalizations of the Scharfetter-Gummel scheme for degenerate semiconductors (Fermi-Dirac statistics) obeying the Kelvin formula. The approaches differ in the treatment of degeneration effects: The first is based on an approximation of the discrete generalized Einstein relation implying a specifically modified thermal voltage, whereas the second scheme follows the conventionally used approach employing a modified electric field. We present a detailed analysis and comparison of both schemes, indicating a superior performance of the modified thermal voltage scheme.

description: We consider the topological B-model on local Calabi-Yau geometries. We show how one can solve for the amplitudes by using W-algebra symmetries which encodes the symmetries of holomorphic diffeomorphisms of the Calabi-Yau. In the highly effective fermionic/brane formulation this leads to a free fermion description of the amplitudes. Furthermore we argue that topological strings on Calabi-Yau geometries provide a unifying picture connecting non-critical (super)strings, integrable hierarchies, and various matrix models. In particular we show how the ordinary matrix model, the double scaling limit of matrix models, and Kontsevich-like matrix model are all related and arise from studying branes in specific local Calabi-Yau three-folds. We also show how A-model topological string on P^1 and local toric threefolds (and in particular the topological vertex) can be realized and solved as B-model topological string amplitudes on a Calabi-Yau manifold.

description: Efficient and versatile interfaces for the interaction of light with matter are an essential cornerstone for quantum science. A fundamentally new avenue of controlling light-matter interactions has been recently proposed based on the rich interplay of photon-mediated dipole-dipole interactions in structured subwavelength arrays of quantum emitters. Here we report on the direct observation of the cooperative subradiant response of a two-dimensional (2d) square array of atoms in an optical lattice. We observe a spectral narrowing of the collective atomic response well below the quantum-limited decay of individual atoms into free space. Through spatially resolved spectroscopic measurements, we show that the array acts as an efficient mirror formed by only a single monolayer of a few hundred atoms. By tuning the atom density in the array and by changing the ordering of the particles, we are able to control the cooperative response of the array and elucidate the interplay of spatial order and dipolar interactions for the collective properties of the ensemble. Bloch oscillations of the atoms out of the array enable us to dynamically control the reflectivity of the atomic mirror. Our work demonstrates efficient optical metamaterial engineering based on structured ensembles of atoms and paves the way towards the controlled many-body physics with light and novel light-matter interfaces at the single quantum level.

description: In this paper, we propose a new dynamical model to study the two-stage volatility evolution of stock market index after extreme events, and find that the volatility after extreme events follows a stretched exponential decay in the initial stage and becomes a power law decay at later times by using high frequency minute data. Empirical study of the evolutionary behaviors of volatility after endogenous and exogenous events further demonstrates the descriptive power of our new model. To further explore the underlying mechanisms of volatility evolution, we introduce the sequential arrival of information hypothesis (SAIH) and the mixture of distribution hypothesis (MDH) to test the two-stage assumption, and find that investors transform from the uninformed state to the informed state in the first stage and informed investors subsequently dominate in the second stage. The testing results offer a supporting explanation for the validity of our new model and the fitted values of relevant parameters.
title: Financial Administration and Accounting as Institutional Development in an African University - Learning from Research Organisation at Eduardo Mondlane University, in Mozambique
Creators: name: Rodrigues Diniz, Célia Maria
Publisher: name: The Open University
Year: 2001

description: This thesis describes an institutional development history of a university coming out of colonial rule, through the days when-it had full national support for its central role for national development, leading to a period when the university had increasing difficulties claiming support for it. It examines the successes and failures of drawing up and implementing a strategic plan for university institutional development at Eduardo Mondlane University (UEM), Mozambique. The most positive result was to draw up the university's first strategic plan to transform the institution and to implement and build on it. The most difficult problem was the internal organisational weaknesses that constrained the institution in its implementation of the plan as scheduled, including those of finance and accountancy.

 The plan was well received by government and the donor community and became a model in the region, with other African universities following it. However, the implementation of the plan was not as successful at least in part because it was critically naive about the level of resources the universities could claim. This lack of realism about accountability was deep-rooted: organisational development was unbalanced with specialists trained - but little training of integrators/managers. Examples of research funding and project planning demonstrate that the sense.of realism and accountability can be learned, but may best be learned through establishing systems of financial control. The thesis suggests more consistent management systems. The expanded use of a simple financial tool illustrated the need to change and improve the financial and accounting systems of the university.

 The thesis argues that the development of African universities should take into account not only strategic decisions at the macro and leadership level, but also the implementation capacity of academic and administrative staff, including the appropriate functioning financial management and accounting systems.
Subdynamics of fluctuations in an equilibrium classical many-particle system and generalized linear Boltzmann and Landau equations

description: New exact completely closed homogeneous Generalized Master Equations (GMEs), governing the evolution in time of equilibrium two-time correlation functions for dynamic variables of a subsystem of s particles (s>1 particles of a classical many-body system, are obtained These time-convolution and time-convolutionless GMEs differ from the known GMEs (e.g. Nakajima-Zwanzig GME) by absence of inhomogeneous terms containing correlations between all N particles at the initial moment of time and preventing the closed description of s-particles subsystem evolution. Closed homogeneous GMEs describing the subdynamics of fluctuations are obtained by applying a special projection operator to the Liouville equation governing the dynamics of N-particle system. In the linear approximation in the particles' density, the linear Generalized Boltzmann equation accounting for initial correlations and valid at all timescales is obtained This equation for a weak inter-particle interaction converts into the generalized linear Landau equation in which the initial correlations are also accounted for. Connection of these equations to the nonlinear Boltzmann and Landau equations are discussed.

We show how such fabrication method can provide interesting potentialities to design doped multimode optical fibers with homogeneous and quasi-parabolic refractive-index core profile for nonlinear optics applications.

description: On non-Kähler manifolds the notion of harmonic maps is modified to that of Hermitian harmonic maps in order to be compatible with the complex structure. The resulting semilinear elliptic system is {\it not} in divergence form. The case of noncompact complete preimage and target manifolds is considered. We give conditions for existence and uniqueness of Hermitian-harmonic maps and solutions of the corresponding parabolic system, which observe the non-divergence form of the underlying equations. Numerous examples illustrate the theoretical results and the fundamental difference to harmonic maps.
