description: Recently, many self-supervised learning methods for image reconstruction have been proposed that can learn from noisy data alone, bypassing the need for ground-truth references. Most existing methods cluster around two classes: i) Stein's Unbiased Risk Estimate (SURE) and similar approaches that assume full knowledge of the noise distribution, and ii) Noise2Self and similar cross-validation methods that require very mild knowledge about the noise distribution. The first class of methods tends to be impractical, as the noise level is often unknown in real-world applications, and the second class is often suboptimal compared to supervised learning. In this paper, we provide a theoretical framework that characterizes this expressivity-robustness trade-off and propose a new approach based on SURE, but unlike the standard SURE, does not require knowledge about the noise level. Throughout a series of experiments, we show that the proposed estimator outperforms other existing self-supervised methods on various imaging inverse problems.

description: Reinforcement learning (RL) can be used to create a tactical decision-making agent for autonomous driving. However, previous approaches only output decisions and do not provide information about the agent's confidence in the recommended actions. This paper investigates how a Bayesian RL technique, based on an ensemble of neural networks with additional randomized prior functions (RPF), can be used to estimate the uncertainty of decisions in autonomous driving. A method for classifying whether or not an action should be considered safe is also introduced. The performance of the ensemble RPF method is evaluated by training an agent on a highway driving scenario. It is shown that the trained agent can estimate the uncertainty of its decisions and indicate an unacceptable level when the agent faces a situation that is far from the training distribution. Furthermore, within the training distribution, the ensemble RPF agent outperforms a standard Deep Q-Network agent. In this study, the estimated uncertainty is used to choose safe actions in unknown situations. However, the uncertainty information could also be used to identify situations that should be added to the training process.

description: The barrel region of the CMS pixel detector will be equipped with ``n-in-n'' type silicon sensors. They are processed on DOFZ material, use the moderated p-spray technique and feature a bias grid. The latter leads to a small fraction of the pixel area to be less sensitive to particles. In order to quantify this inefficiency prototype pixel sensors irradiated to particle fluences between $4.7\times 10^{13}$ and $2.6\times 10^{15} \Neq$ have been bump bonded to un-irradiated readout chips and tested using high energy pions at the H2 beam line of the CERN SPS. The readout chip allows a non zero suppressed analogue readout and is therefore well suited to measure the charge collection properties of the sensors. In this paper we discuss the fluence dependence of the collected signal and the particle detection efficiency. Further the position dependence of the efficiency is investigated.

description: We make a theoretical study of the s-wave interaction of the nonet of vector mesons with the octet of pseudoscalar mesons starting from a chiral invariant Lagrangian and implementing unitarity in coupled channels. By looking for poles in the unphysical Riemann sheets of the unitarized scattering amplitudes, we get two octets and one singlet of axial-vector dynamically generated resonances. The poles found can be associated to most of the low lying axial-vector resonances quoted in the Particle Data Book: $b_1(1235)$, $h_1(1170)$, $h_1(1380)$, $a_1(1260)$, $f_1(1285)$ and two poles to the $K_1(1270)$ resonance. We evaluate the couplings of the resonances to the $VP$ states and the partial decay widths in order to reinforce the arguments in the discussion.

description: The assumption of homogeneity between family and hired farm labor is common in farm labor research. Controlling for region and farm size, this study employs a seemingly unrelated regression analysis to jointly estimate a translog cost function and factor cost shares to determine the elasticity of substitution between hired and family farm labor. The results show an evidence of heterogeneity of farm labor in both cash grain and hog farms in the U.S. There is further evidence that the elasticity of substitution is unitary and the cost minimizing ratio of hired and family labor is not independent of time. Regional factors were found to have little effect on the substitutability of farm labor, whereas farm size was found to have a significant influence on the relationship between hired and family labor.
Are Type Ia Supernovae in Restframe $H$ Brighter in More Massive Galaxies?

description: We analyze 143 Type Ia supernovae (SNeIa) observed in $H$ band (1.6-1.8 $μ$m) and find SNeIa are intrinsically brighter in $H$-band with increasing host galaxy stellar mass. We find SNeIa in galaxies more massive than $10^{10.43} M_{\odot}$ are $0.13 \pm 0.04$ mag brighter in $H$ than SNeIa in less massive galaxies. The same set of SNeIa observed at optical wavelengths, after width-color-luminosity corrections, exhibit a $0.10 \pm 0.03$ mag offset in the Hubble residuals. We observe an outlier population ($|ΔH_{\rm max}| > 0.5$ mag) in the $H$ band and show that removing the outlier population moves the mass threshold to $10^{10.65} M_{\odot}$ and reduces the step in $H$ band to $0.08 \pm 0.04$ mag, but the equivalent optical mass step is increased to $0.13 \pm 0.04$ mag. We conclude the outliers do not drive the brightness--host-mass correlation. Less massive galaxies preferentially host more higher-stretch SNeIa, which are intrinsically brighter and bluer. It is only after correction for width-luminosity and color-luminosity relationships that SNeIa have brighter optical Hubble residuals in more massive galaxies. Thus finding SNeIa are intrinsically brighter in $H$ in more massive galaxies is an opposite correlation to the intrinsic (pre-width-luminosity correction) optical brightness. If dust and the treatment of intrinsic color variation were the main driver of the host galaxy mass correlation, we would not expect a correlation of brighter $H$-band SNeIa in more massive galaxies.

description: In this paper, we propose long short term memory speech enhancement network (LSTMSE-Net), an audio-visual speech enhancement (AVSE) method. This innovative method leverages the complementary nature of visual and audio information to boost the quality of speech signals. Visual features are extracted with VisualFeatNet (VFN), and audio features are processed through an encoder and decoder. The system scales and concatenates visual and audio features, then processes them through a separator network for optimized speech enhancement. The architecture highlights advancements in leveraging multi-modal data and interpolation techniques for robust AVSE challenge systems. The performance of LSTMSE-Net surpasses that of the baseline model from the COG-MHEAR AVSE Challenge 2024 by a margin of 0.06 in scale-invariant signal-to-distortion ratio (SISDR), $0.03$ in short-time objective intelligibility (STOI), and $1.32$ in perceptual evaluation of speech quality (PESQ).

description: Housing delivery within South Africa, and specifically the Eastern Cape, is constrained by a variety of pressing issues. Significant nation-wide barriers include fiscal decentralization, supply driven inefficiencies, non-sustainability and bureaucratic failure. More specific factors and trends are highlighted through juxtaposing the normative policy aims with two case study assessments of local municipalities. These various instances of politico-economic failure appear to be bypassed via social housing initiatives; however, theoretical and practical recommendations lend themselves towards the immediate renewal of the current housing program.

description: We introduce a deep-recessed gate architecture in $β$-Ga$_2$O$_3$ delta-doped field effect transistors for improvement in DC-RF dispersion and breakdown properties. The device design incorporates an unintentionally doped $β$-Ga$_2$O$_3$ layer as the passivation dielectric. To fabricate the device, the deep-recess geometry was developed using BCl$_3$ plasma based etching at ~5 W RIE to ensure minimal plasma damage. Etch damage incurred with plasma etching was mitigated by annealing in vacuum at temperatures above 600 $°$C. A gate-connected field-plate edge termination was implemented for efficient field management. Negligible surface dispersion with lower knee-walkout at high V$_\mathrm{DS}$, and better breakdown characteristics compared to their unpassivated counterparts were achieved. A three terminal off-state breakdown voltage of 315 V, corresponding to an average breakdown field of 2.3 MV/cm was measured. The device breakdown was limited by the field-plate/passivation edge and presents scope for further improvement. This demonstration of epitaxially passivated field effect transistors is a significant step for $β$-Ga$_2$O$_3$ technology since the structure simultaneously provides control of surface-related dispersion and excellent field management.

description: South African research has found tertiary education to have the highest rate of return amongst levels of education. Measures of effectiveness of the large allocation by government are a crucial area of study relatively untapped. Income levels relative to level of education were found to have significant correlation with probability of entering into an income bracket of above R8 000 being 2.3 times higher with a tertiary degree. A sample of Rhodes University NSFAS funded students, analysed within the framework of a cost benefit equation, indicated the positive effect of government funding on rates of return.

We find that in the last conductance plateau the transport is unexpectedly dominated by a well-transmitting single conduction channel. We explain the experimental findings with the help of a tight-binding model which shows that in an one-atom Zn contact the current proceeds through the 4s and 4p orbitals of the central atom.

description: We introduce a formal notion of defendability against backdoors using a game between an attacker and a defender. In this game, the attacker modifies a function to behave differently on a particular input known as the "trigger", while behaving the same almost everywhere else. The defender then attempts to detect the trigger at evaluation time. If the defender succeeds with high enough probability, then the function class is said to be defendable. The key constraint on the attacker that makes defense possible is that the attacker's strategy must work for a randomly-chosen trigger.
 Our definition is simple and does not explicitly mention learning, yet we demonstrate that it is closely connected to learnability. In the computationally unbounded setting, we use a voting algorithm of Hanneke et al. (2022) to show that defendability is essentially determined by the VC dimension of the function class, in much the same way as PAC learnability. In the computationally bounded setting, we use a similar argument to show that efficient PAC learnability implies efficient defendability, but not conversely. On the other hand, we use indistinguishability obfuscation to show that the class of polynomial size circuits is not efficiently defendable. Finally, we present polynomial size decision trees as a natural example for which defense is strictly easier than learning. Thus, we identify efficient defendability as a notable intermediate concept in between efficient learnability and obfuscation.

description: The Time Domain-Electric Field Integral Equation (TD-EFIE) and its differentiated version are widely used to simulate the transient scattering of a time dependent electromagnetic field by a Perfect Electrical Conductor (PEC). The time discretization of the TD-EFIE can be achieved by a space-time Galerkin approach or, as it is considered in this contribution, by a convolution quadrature using Implicit Runge-Kutta methods. The solution is then computed using the Marching-On-in-Time (MOT) algorithm. The differentiated TD-EFIE has two problems: (i) the system matrix suffers from ill-conditioning when the time step increases (low frequency breakdown) and (ii) it suffers from the DC instability, i.e. the formulation allows for the existence of spurious solenoidal currents that grow slowly in the solution. In this work, we show that (i) and (ii) can be alleviated by leveraging quasi-Helmholtz projectors to separate the Helmholtz components of the induced current and rescale them independently. The efficacy of the approach is demonstrated by numerical examples including benchmarks and real life applications.

description: The possibility of using strongly and continuously interacting spins for quantum computation has recently been discussed. Here we present a simple optical scheme that achieves this goal while avoiding the drawbacks of earlier proposals. We employ a third state, accessed by a classical laser field, to create an effective barrier to information transfer. The mechanism proves to be highly efficient both for continuous and pulsed laser modes; moreover it is very robust, tolerating high decay rates for the excited states. The approach is applicable to a broad range of systems, in particular dense structures such as solid state self-assembled (e.g., molecular) devices. Importantly, there are existing structures upon which `first step' experiments could be immediately performed.

A hand-held probe for vibro-elastography
Creators: name: Rivaz, Hassan
Publisher: name: University of British Columbia
Year: 2009

description: Vibro-elastography is a new medical imaging method that identifies the mechanical properties of tissue by measuring tissue motion in response to a multi-frequency external vibration source. Previous research on vibro-elastography used ultrasound to measure the tissue motion and system identification techniques to identify the tissue properties. This thesis describes a hand-held probe with a combined vibration source and ultrasound transducer which is operational in the 5-25 Hz range to cover a significant bandwidth of the tissue response. The design uses a vibration absorption system to counter-balance the reaction forces from contact with the tissue. Four different types of vibration absorption are briefly described and among them, active dynamic vibration absorption is selected for the hand-held device. A proportional integrator control is designed for the active vibration absorption and is compared with a well-established active vibration absorption method, the delayed resonator. An electromagnetic actuator is selected for active vibration absorption with a single accelerometer providing the feedback. The dynamics of the electromagnetic actuator as well as the response of the different niters are considered in the control law. The stability of the both absorber system and the combined system are considered to find the operational frequency range. The concept of tuning speed for different vibration absorbers is elaborated and is related to the vibration absorption speed. The design of the hand-held device, which includes the active vibration absorber, is presented next. The design utilizes another electromagnetic actuator which is used to vibrate the tissue and is operated with displacement feedback. The design of the vibration absorber is elaborated next. In this design the effect of different absorber parameters on the actuator stroke, control force, stability of the combined system and the tuning speed of the absorber is studied. After manufacturing the device, the absorber parameters are identified in order to optimize the vibration absorption performance. Simulation results are provided next that verify the theories presented on the stability and tuning speed. The results show that 100% vibration absorption can be achieved in steady state for both the proportional integrator and the delayed resonator controllers. They also show that nonlinearities in the absorber system decrease the amount of vibration absorption. Experimental results are presented next, showing approximately 85% vibration absorption in the operational range. The existing parameter identification methods that identify the mechanical properties of the tissue using the ultrasound are modified for the hand-held device. Simulation results are provided to validate the revised parameter identification methods. The first elastograms obtained with the hand-held device are finally presented.

description: Modern browsers give access to several attributes that can be collected to form a browser fingerprint. Although browser fingerprints have primarily been studied as a web tracking tool, they can contribute to improve the current state of web security by augmenting web authentication mechanisms. In this paper, we investigate the adequacy of browser fingerprints for web authentication. We make the link between the digital fingerprints that distinguish browsers, and the biological fingerprints that distinguish Humans, to evaluate browser fingerprints according to properties inspired by biometric authentication factors. These properties include their distinctiveness, their stability through time, their collection time, their size, and the accuracy of a simple verification mechanism. We assess these properties on a large-scale dataset of 4,145,408 fingerprints composed of 216 attributes, and collected from 1,989,365 browsers. We show that, by time-partitioning our dataset, more than 81.3% of our fingerprints are shared by a single browser. Although browser fingerprints are known to evolve, an average of 91% of the attributes of our fingerprints stay identical between two observations, even when separated by nearly 6 months. About their performance, we show that our fingerprints weigh a dozen of kilobytes, and take a few seconds to collect. Finally, by processing a simple verification mechanism, we show that it achieves an equal error rate of 0.61%. We enrich our results with the analysis of the correlation between the attributes, and of their contribution to the evaluated properties. We conclude that our browser fingerprints carry the promise to strengthen web authentication mechanisms.

description: Получена формализованная модель типа Коши процесса усвоения знаний, основанная на закономерностях самоорганизации процесса обучения и его составляющих, в рамках нелинейных дифференциальных соотношений с возможностью динамического изменения параметров модели, в том числе возникновения хаоса за счет бифуркационных явлений. Разработаны новые и адаптированы к условиям цифровизации образования известные математические модели процесса усвоения знаний и оценки остаточных знаний обучаемых в вузах, учитывающие как накопление, так и рассеяние знаний в процессе обучения.
description: A formalized model of Cauchy type for knowledge assimilation based on the patterns of self-organization of educational process and its components is obtained in the framework of non-linear non-differential relationships with the possibility for dynamical change of model’s parameters, including the occurrence of chaos due to the bifurcation phenomena. New known mathematical models, which consider both knowledge accumulation and dispersal in the educational process, for knowledge assimilation and assessment of remaining knowledge of students from universities are developed and adapted for educational digitalization.

description: The economics of a Payment for Watershed Services (PWS) is examined as a way to finance the restoration of the Baviaans catchment. The proposed PWS consists of Gamtoos-valley farmers “buying” watershed services from upstream farmers in the Western Baviaanskloof, who need to change their farming practices to ensure the delivery of this service. The economic valuation of the watershed services is discussed and it is found that, although more quantitative and scientific research is necessary, the downstream farmers will reap economic benefits and that both parties are willing to participate in the scheme. This is a synthesis paper written for PRESENCE.

description: При построении квазилинейных регрессионных моделей возникает проблема выбора оптимального соотношения между их точностью и нелинейностью. Цель работы заключается во внедрении разработанных ранее критериев нелинейности по площади в технологию организации «конкурса» моделей. Для этого сформулирована двухкритериальная задача, состоящая в максимизации коэффициента детерминации и одновременной минимизации критерия нелинейности, и предложено два способа ее решения. Первый способ основан на формировании множества Парето, с помощью которого можно визуально выбрать наиболее приемлемую альтернативу. Второй способ более эффективен с вычислительной точки зрения, поскольку на первом его этапе исключаются значительно нелинейные переменные. Затем из возможных спецификаций выбирается регрессия с наибольшим значением коэффициента детерминации. Предложенные способы решения двухкритериальной задачи продемонстрированы на примере моделирования работы выпарного аппарата.
description: The problem of selecting the optimum relationship between the accuracy and non-linearity is arising when constructing quasi-linear regression models. A two-criterial problem consisting of maximizing the coefficient of determinant and simultaneous minimization of non-linearity criterion was formed to implement the previously developed criteria of non-linearity for area into the technology of arrangement of models “competition”. Two methods were proposed to solve the problem. The first method is based on the Pareto set, which makes it possible to visually select the most suitable alternative. The second method is more efficient from the calculating point of view as it eliminates the highly non-linear variables. After that, the regression with the highest value of the determinant coefficient is being selected out of possible specifications. The proposed methods for solution of two-criterial problem are demonstrated on the example of stimulating the operation of an evaporator.

description: Исследуется излучение нейтральной частицы, обладающей магнитным моментом и совершающей неинерциальное движение в поперечном магнитном поле. Мощность излучения обнаруживает асимметричную зависимость от горизонтальных спиновых компонент. Для релятивистского и нерелятивистского движений симметрия восстанавливается, при этом в первом случае излучение имеется при любой ориентации спина, во втором – отсутствует, если ς || H . В случае равномерного движения полученное здесь выражение для мощности
совпадает с найденными ранее в классической и квантовой теории.
description: The radiation of neutral particle that carries magnetic moment and executes non-inertial motion in the transverse magnetic field is analyzed. The power of radiation shows the asymmetric dependence on the horizontal spin components. The symmetry is restored for the ultra-relativistic and non-relativistic motions. At the same time, the first case shows the presence of radiation at either spin orientation whereas in the second case the radiation is absent when ς || H . In the case of uniform motion, the power expression obtained in the study coincides with the ones known from both the classical and the quantum theory.

THE CONTRIBUTION OF CORPORATE SAVINGS IN SOUTH AFRICA TO RECENT RECORD CURRENT ACCOUNT DEFICITS

description: Recently South Africa recorded record current account deficits at a time of high commodity prices. A major contributor to these deficits was a lower level of corporate saving. Low domestic savings makes South Africa reliant on foreign capital inflows to fund higher investment levels and the resultant current account deficits. This paper seeks to identify reasons for the fall in corporate saving using econometric techniques to analyse the relationships between corporate saving and six explanatory macroeconomic variables. Significant variables identified are the real effective exchange rate, a commodity price index and a coincident business cycle indicator. The results show that these variables explain most of the variation in corporate saving, although they do not conform to a priori expectations.
Interpretation of the in-plane infrared response of the high-Tc cuprate superconductors involving spin fluctuations revisited

description: The in-plane infrared response of the high-Tc cuprate superconductors was studied using the spin-fermion model, where charged quasiparticles of the copper-oxygen planes are coupled to spin fluctuations. First, we analyzed structures of the superconducting-state conductivity reflecting the coupling of the quasiparticles to the resonance mode observed by neutron scattering. The conductivity computed with the input spin susceptibility in the simple form of the mode exhibits two prominent features: an onset of the real part of the conductivity starting around the frequency of the mode omega_{0} and a maximum of a related function W(omega), roughly proportional to the second derivative of the scattering rate, centered approximately at omega=omega_{0}+Delta_{0}/hbar, where Delta_{0} is the maximum value of the superconducting gap. The two structures are well known from earlier studies. Their physical meaning, however, has not been sufficiently elucidated thus far. Our analysis involving quasiparticle spectral functions provides a clear interpretation. Second, we explored the role played by the spin-fluctuation continuum. Third, we investigated the temperature dependence of the conductivity, of the intraband spectral weight, and of the effective kinetic energy. The changes of the latter two quantities below Tc are determined by the formation of the gap, by a feedback effect of the spin fluctuations on the quasiparticles, and by a significant shift of the chemical potential.

Regimes of Steady-State Turbulence in a Quantum Fluid

description: We simulate the Gross-Pitaevskii equation to model the development of turbulence in a quantum fluid confined by a cuboid box potential, and forced by shaking along one axis. We observe the development of isotropic turbulence from anisotropic forcing for a broad range of forcing amplitudes, and characterise the states through their Fourier spectra, vortex distributions, and spatial correlations. For weak forcing the steady-state wave-action spectrum exhibits a $k^{-3.5}$ scaling over wavenumber $k$; further decomposition uncovers the same power law in both compressible kinetic energy and quantum pressure, while the bulk superfluid remains phase coherent and free from extended vortices. As the forcing energy exceeds the chemical potential, extended vortices develop in the bulk, disrupting the $k^{-3.5}$ scaling. The spectrum then transitions to a $k^{-7/3}$ regime for compressible kinetic energy only, associated with dense vortex turbulence, and phase coherence limited to the healing length. The strong forcing regime is consistent with an inverse cascade of compressible energy driven by small-scale vortex annihilation.
