description: Objects are concrete things, sharply separated from their surroundings - at least that is how they might appear to us in our everyday lives. It is by creating processes of transformation that we can deconstruct this firm notion of what an object is. When the focus shifts to the process of destruction, or - in other words - the timespan of transformation, we can grasp that there is no beginning, nor end to the objects that seem so clearly defined in our mind.

description: We introduce a numerical package FORward Experiment SEnsitivity Estimator, or FORESEE, that can be used to simulate the expected sensitivity reach of experiments placed in the far-forward direction from the proton-proton interaction point. The simulations can be performed for $14$ TeV collision energy characteristic for the LHC, as well as for larger energies: $27$ and $100$ TeV. In the package, a comprehensive list of validated forward spectra of various SM species is also provided. The capabilities of FORESEE are illustrated for the popular dark photon and dark Higgs boson models, as well as for the search for light up-philic scalars. For the dark photon portal, we also comment on the complementarity between such searches and dark matter direct detection bounds. Additionally, for the first time, we discuss the prospects for the LLP searches in the proposed future hadron colliders: High-Energy LHC (HE-LHC), Super proton-proton Collider (SppC), and Future Circular Collider (FCC-hh).

A Proximal Decomposition Method for Solving Convex Variational Inverse Problems

Subjects: subject: Optimization and Control (math.OC)

description: A broad range of inverse problems can be abstracted into the problem of minimizing the sum of several convex functions in a Hilbert space. We propose a proximal decomposition algorithm for solving this problem with an arbitrary number of nonsmooth functions and establish its convergence. The algorithm fully decomposes the problem in that it involves each function individually via its own proximity operator. A significant improvement over the methods currently in use in the area of inverse problems is that it is not limited to two nonsmooth functions. Numerical applications to signal and image processing problems are demonstrated.

description: Purple passion fruit, one of the most important fruit exports in Colombia, has been seriously affected in recent years by several viral diseases. The aim of the present study was to investigate the virome of asymptomatic purple passion fruit samples from commercial plots and nurseries in Antioquia (Colombia). The presence of viruses was first tested by high-throughput sequencing (HTS) of bulked leaf samples using total RNA and dsRNA inputs. Interestingly, the HTS data suggested the presence of a new badnavirus with a genome of 6,951 bp, which was confirmed by DNA sequencing of rolling circle amplification products. This virus has been tentatively named Badnavirus passiflorae as it is the first report of a badnavirus infecting passion fruit. The presence of Soybean mosaic virus (SMV), Cowpea aphid-borne mosaic virus (CABMV), Cucumber mosaic virus (CMV), and Passion fruit yellow mosaic virus (PFYMV) was further investigated using RT-qPCR, as well as evaluated the infection by begomoviruses and badnaviruses through PCR. Using these techniques, B. passiflorae was detected in all the samples, PFYMV in 20% of adult plants and 10% of plantlets, and SMV in 20% of adult plants and 30% of plantlets. None of the samples tested positive for CABMV, CMV, or begomoviruses.

data pruning

description: Could a training example be detrimental to learning? Contrary to the common belief that more training data is needed for better generalization, we show that the learning algorithm might be better off when some training examples are discarded. In other words, the quality of the examples matters.

We explore a general approach to identify examples that are troublesome for learning with a given model and exclude them from the training set in order to achieve better generalization. We term this process 'data pruning'. The method is targeted as a pre-learning step in order to obtain better data to train on.

The approach consists in creating multiple semi-independent learners from the dataset each of which is influenced differently by individual examples. The multiple learners' opinions about which example is difficult are arbitrated by an inference mechanism. Although, without guarantees of optimality, data pruning is shown to decrease the generalization error in experiments on real-life data. It is not assumed that the data or the noise can be modeled or that additional training examples are available.

Data pruning is applied for obtaining visual category data with little supervision. In this setting the object data is contaminated with non-object examples. We show that a mechanism for pruning noisy datasets prior to learning can be very successful especially in the presence of large amount of contamination or when the algorithm is sensitive to noise.

Our experiments demonstrate that data pruning can be worth while even if the algorithm has regularization capabilities or mechanisms to cope with noise and has a potential to be a more refined method for regularization or model selection.

description: We provide further evidence to support the fact that a four-dimensional effective field theory description with de Sitter isometries in IIB string theory, overcoming the no-go and the swampland criteria, can only exist if de Sitter space is realized as a Glauber-Sudarshan state. We show here that this result is independent of the choice of de Sitter slicings. The Glauber-Sudarshan state, constructed by shifting the interacting vacuum in the M-theory uplift of the scenario, differs from a standard coherent state in QFT in the sense that the shape and size of the state changes with respect to time, implying changes in the graviton and the flux quanta. Despite this, the expectation values of the graviton and flux operators in such a state reproduce the exact de Sitter background, as long as we are within the temporal bound set by the onset of the strong coupling in the dual type IIA side, and satisfy the corresponding Schwinger-Dyson's equations in the presence of hierarchically controlled perturbative and non-perturbative quantum corrections. Additionally, we provide a detailed study of the fluxes supporting the Glauber-Sudarshan state in the M-theory uplift of the IIB scenario. We show explicitly how the Bianchi identities, anomaly cancellation and flux quantization conditions, along-with the constraints from the Schwinger-Dyson's equations, conspire together to provide the necessary temporal dependences to support such a state in full M-theory. We also discuss how our analysis points towards a surprising connection to the four-dimensional null energy condition, for a Friedman-Lemaitre-Robertson-Walker state in the IIB side, as a consistency condition for the existence of an effective field theory description in M-theory.

description: Eight inbred lines along with twenty-eight F1 hybrids were used to study the combining ability for 13 morphological traits in periwinkle (Catharanthus roseus). The parental lines were P1 (Magenta with white centre), P2 (Magenta), P3 (Cherry pink), P4 (Peach), P5 (Purple), P6 (Pink with dark pink centre), P7 (Light pink with white centre) and P8 (White with red spot). The mean squares due to combining ability exhibited highly significant general combining ability (GCA) and specific combining ability (SCA) effects for most of the traits. Parental lines P5 and P8 had desirable GCA effects for most of the traits. Regarding SCA, the majority of the significant effects were obtained in cross combinations involving poor or average lines crossed to good or poor lines. Additive gene action was found to be influencing plant height, leaf width, petiole length, days to flowering and corolla tube length. However, plant spread, number of branches per plant, leaf length, internodal length, flowering duration, number of flowers per plant, flower diameter and follicle length were found to be controlled by non-additive genetic components. Therefore, selection or hybridisation can be employed for the improvement of these traits on the basis of their genetic control.

description: Proposed in this paper is a kinetostatic performance index for the optimum dimensioning of planar manipulators of the serial type. The index is based on the concept of distance of the underlying Jacobian matrix to a given isotropic matrix that is used as a reference model for purposes of performance evaluation. Applications of the index fall in the realm of design, but control applications are outlined. The paper focuses on planar manipulators, the basic concepts being currently extended to their three-dimensional counterparts.

description: Light transmission through 2D subwavelength hole arrays in perfect-conductor films is shown to be complete (100%) at some resonant wavelengths even for arbitrarily narrow holes. Conversely, the reflection on a 2D planar array of non-absorbing scatterers is shown to be complete at some wavelengths regardless how weak the scatterers are. These results are proven analytically and corroborated by rigorous numerical solution of Maxwell's equations. This work supports the central role played by dynamical diffraction during light transmission through subwavelength hole arrays and it provides a systematics to analyze more complex geometries and many of the features observed in connection with transmission through hole arrays.

Assessing the detectability of the secondary spin in extreme mass-ratio inspirals with fully-relativistic numerical waveforms

description: Extreme mass-ratio inspirals~(EMRIs) detectable by the Laser Inteferometric Space Antenna~(LISA) are unique probes of astrophysics and fundamental physics. Parameter estimation for these sources is challenging, especially because the waveforms are long, complicated, known only numerically, and slow to compute in the most relevant regime, where the dynamics is relativistic. We perform a time-consuming Fisher-matrix error analysis of the EMRI parameters using fully-relativistic numerical waveforms to leading order in an adiabatic expansion on a Kerr background, taking into account the motion of the LISA constellation, higher harmonics, and also including the leading correction from the spin of the secondary in the post-adiabatic approximation. We pay particular attention to the convergence of the numerical derivatives in the Fisher matrix and to the numerical stability of the covariance matrix, which for some systems requires computing the numerical waveforms with approximately $90$-digit precision. Our analysis confirms previous results (obtained with approximated but much more computationally efficient waveforms) for the measurement errors on the binary's parameters. We also show that the inclusion of higher harmonics improves the errors on the luminosity distance and on the orbital angular momentum angles by one order and two orders of magnitude, respectively, which might be useful to identify the environments where EMRIs live. We particularly focus on the measurability of the spin of the secondary, confirming that it cannot be measured with sufficient accuracy. However, due to correlations, its inclusion in the waveform model can deteriorate the accuracy on the measurements of other parameters by orders of magnitude, unless a physically-motivated prior on the secondary spin is imposed.

description: Quantitative phase imaging (QPI) is a valuable label-free modality that has gained significant interest due to its wide potentials, from basic biology to clinical applications. Most existing QPI systems measure microscopic objects via interferometry or nonlinear iterative phase reconstructions from intensity measurements. However, all imaging systems compromise spatial resolution for field of view and vice versa, i.e., suffer from a limited space bandwidth product. Current solutions to this problem involve computational phase retrieval algorithms, which are time-consuming and often suffer from convergence problems. In this article, we presented synthetic aperture interference light (SAIL) microscopy as a novel modality for high-resolution, wide field of view QPI. The proposed approach employs low-coherence interferometry to directly measure the optical phase delay under different illumination angles and produces large space-bandwidth product (SBP) label-free imaging. We validate the performance of SAIL on standard samples and illustrate the biomedical applications on various specimens: pathology slides, entire insects, and dynamic live cells in large cultures. The reconstructed images have a synthetic numeric aperture of 0.45, and a field of view of 2.6 x 2.6 mm2. Due to its direct measurement of the phase information, SAIL microscopy does not require long computational time, eliminates data redundancy, and always converges.

description: Simulating crowds requires controlling a very large number of trajectories and is usually performed using crowd motion algorithms for which appropriate parameter values need to be found. The study of the relation between parametric values for simulation techniques and the quality of the resulting trajectories has been studied either through perceptual experiments or by comparison with real crowd trajectories. In this paper, we integrate both strategies. A quality metric, QF, is proposed to abstract from reference data while capturing the most salient features that affect the perception of trajectory realism. QF weights and combines cost functions that are based on several individual, local and global properties of trajectories. These trajectory features are selected from the literature and from interviews with experts. To validate the capacity of QF to capture perceived trajectory quality, we conduct an online experiment that demonstrates the high agreement between the automatic quality score and non-expert users. To further demonstrate the usefulness of QF, we use it in a data-free parameter tuning application able to tune any parametric microscopic crowd simulation model that outputs independent trajectories for characters. The learnt parameters for the tuned crowd motion model maintain the influence of the reference data which was used to weight the terms of QF.

description: Consider a number of moving points, where each point is attached to a joint of the human body and projected onto an image plane. Johannson showed that humans can effortlessly detect and recognize the presence of other humans from such displays. This is true even when some of the body points are missing (e.g. because of occlusion) and unrelated clutter points are added to the display. We are interested in replicating this ability in a machine. To this end, we present a labeling and detection scheme in a probabilistic framework. Our method is based on representing the joint probability density of positions and velocities of body points with a graphical model, and using Loopy Belief Propagation to calculate a likely interpretation of the scene. Furthermore, we introduce a global variable representing the body's centroid. Experiments on one motion-captured sequence suggest that our scheme improves on the accuracy of a previous approach based on triangulated graphical models, especially when very few parts are visble. The improvement is due both to the more general graph structure we use and, more significantly, to the introduction of the centroid variable.

description: The commonly used latent space embedding techniques, such as Principal Component Analysis, Factor Analysis, and manifold learning techniques, are typically used for learning effective representations of homogeneous data. However, they do not readily extend to heterogeneous data that are a combination of numerical and categorical variables, e.g., arising from linked GPS and text data. In this paper, we are interested in learning probabilistic generative models from high-dimensional heterogeneous data in an unsupervised fashion. The learned generative model provides latent unified representations that capture the factors common to the multiple dimensions of the data, and thus enable fusing multimodal data for various machine learning tasks. Following a Bayesian approach, we propose a general framework that combines disparate data types through the natural parameterization of the exponential family of distributions. To scale the model inference to millions of instances with thousands of features, we use the Laplace-Bernstein approximation for posterior computations involving nonlinear link functions. The proposed algorithm is presented in detail for the commonly encountered heterogeneous datasets with real-valued (Gaussian) and categorical (multinomial) features. Experiments on two high-dimensional and heterogeneous datasets (NYC Taxi and MovieLens-10M) demonstrate the scalability and competitive performance of the proposed algorithm on different machine learning tasks such as anomaly detection, data imputation, and recommender systems.

description: In this study, we present a new instrument, the Participation and Engagement Scale (PES), for the evaluation of the students’ involvement in STEM-oriented activities. The instrument was administered to about 1000 secondary school students who participated in the activities of the Italian Piano Nazionale Lauree Scientifiche in Biology, Chemistry and Physics. The activities were carried out in a remote modality due to the COVID-19 restrictions. Through an exploratory and confirmatory factor analysis, it was possible to validate a two-factor structure of the instrument: satisfaction towards the activities and value of the activities. The proposed factor structure shows a good model fit, with each of the obtained scales displaying excellent reliability. Construct-related validation evidence was obtained through the Rasch analysis, which allowed further psychometric improvement of the instrument. Convergent validation evidence was established through a correlation with the academic motivation and perceived difficulties scales. Using the proposed instrument, we found no statistically significant relationships between engagement, the different types of science activities attended, and the intention to enrol in a STEM course. Implications of the study for the evaluation of public understanding of science activities in both remote and in-presence modalities are also discussed.
A study of numerical techniques for radiative problems in general relativity
Creators: name: Choptuik, Matthew William
Publisher: name: University of British Columbia
Year: 2010

description: There is continuing interest in the numerical solution of the field equations of general relativity. Many of the most interesting scenarios involve the generation and propagation of gravitational radiation—this thesis is an investigation of numerical techniques which should be useful for such problems. The study is based on a model system of a single massless scalar field coupled to the gravitational field, with the additional requirement of spherical symmetry. The 3+1 formalism for numerical relativity is used and attention is limited to finite difference techniques. As a preliminary step, the properties of some difference schemes are examined in the context of the wave equation in general coordinates. The accuracy, stability, convergence, dissipation, dispersion and efficiency of the schemes are discussed and three of the methods, which are all centred, second order approximations, are identified as being suitable for radiation problems in general relativity. Following work by Piran, the model problem is solved in three different coordinate systems using variations of the schemes devised for the wave equation. Various initial configurations of the scalar field are evolved, ranging from cases where there is a negligible amount of gravitational self-interaction to those where black holes are formed. Although some numerical difficulties remain with the latter calculations, the basic difference techniques developed for the treatment of the radiative degrees of freedom are found to be satisfactory. In the past it has been argued that there is a fundamental inconsistency in finite difference solutions of Einstein's equations which are generated by algorithms that do not continuously impose the constraint equations which arise from the coordinate freedom of general relativity. The deviations of freely evolved quantities from discrete versions of the constraint equations are supposedly of lower order (in the mesh spacing) than the underlying difference scheme. An argument based on Richardson's hypothesis concerning the expansion of the error of a difference solution in powers of the mesh spacing is made which suggests that there should be no such inconsistency. Numerical results from two fully second order algorithms are presented in support of this argument. The remainder of the thesis deals with the application of local mesh refinement techniques to the model problem. A simplified version of a recent algorithm due to Berger and Oliger is implemented for one particular coordinate system and is used to examine the nature of the scalar field's gravitational self-interaction.

description: Ions with similar charge-to-mass ratios cannot be separated from existing beam profile monitors (BPMs) in nuclear facilities in which low-energy radioactive ions are produced due to nuclear fusion reactions. In this study, we developed a BPM using a microchannel plate and a charge-coupled device to differentiate the beam profiles of alpha-decaying radioactive isotopes from other ions (reaction products) produced in a nuclear reaction. This BPM was employed to optimize the low-energy radioactive francium ion (Fr+) beam developed at the Cyclotron and Radioisotope Center (CYRIC), Tohoku University, for electron permanent electric dipole moment (e-EDM) search experiments using Fr atoms. We demonstrated the performance of the BPM by separating the Fr+ beam from other reaction products produced during the nuclear fusion reaction of an oxygen (18O) beam and gold (197Au) target. However, as the mass of Au is close to that of Fr, separating the ions of these elements using a mass filter is a challenge, and a dominant number of Au+ renders the Fr+ beam profile invisible when using a typical BPM. Therefore, by employing the new BPM, we could successfully observe the Fr+ beam and other ion beams distinctly by measuring the alpha decay of Fr isotopes. This novel technique to monitor the alpha-emitting radioactive beam covers a broad range of lifetimes, for example, from approximately 1 s to 10 min, and can be implemented for other alpha-emitter beams utilized for medical applications.

description: The true topological nature of the Kondo insulator SmB$_6$ remains to be unveiled. Our previous tunneling study not only found evidence for the existence of surface Dirac fermions, but it also uncovered that they inherently interact with the spin excitons, collective excitations in the bulk. We have extended such a spectroscopic investigation into crystals containing a Sm deficiency. The bulk hybridization gap is found to be insensitive to the deficiency up to 1% studied here, but the surface states in Sm-deficient crystals exhibit quite different temperature evolutions from those in stoichiometric ones. We attribute this to the topological surface states remaining incoherent down to the lowest measurement temperature due to their continued interaction with the spin excitons that remain uncondensed. This result shows that the detailed topological nature of SmB$_6$ could vary drastically in the presence of disorder in the lattice. This sensitiveness to disorder is seemingly contradictory to the celebrated topological protection, but it can be understood as being due to the intimate interplay between strong correlations and topological effects.

description: Investigations on functional selectivity of GPCR ligands have become increasingly important to identify compounds with a potentially more beneficial side effect profile. In order to discriminate between individual signaling pathways, the determination of beta-arrestin2 recruitment, in addition to G-protein activation, is of great value. In this study, we established a sensitive split luciferase-based assay with the ability to quantify beta-arrestin2 recruitment to D-2long and D(3)receptors and measure time-resolved beta-arrestin2 recruitment to the D-2long receptor after agonist stimulation. We were able to characterize several standard (inverse) agonists as well as antagonists at the D2longR and D3R subtypes, whereas for the D4.4R, no beta-arrestin2 recruitment was detected, confirming previous reports. Extensive radioligand binding studies and comparisons with the respective wild-type receptors confirm that the attachment of the Emerald luciferase fragment to the receptors does not affect the integrity of the receptor proteins. Studies on the involvement of GRK2/3 and PKC on the beta-arrestin recruitment to the D-2long R and D3R, as well as at the D1R using different kinase inhibitors, showed that the assay could also contribute to the elucidation of signaling mechanisms. Its broad applicability, which provides concentration-dependent and kinetic information on receptor/beta-arrestin2 interactions, renders this homogeneous assay a valuable method for the identification of biased agonists.

description: In collaborative intelligence applications, part of a deep neural network (DNN) is deployed on a lightweight device such as a mobile phone or edge device, and the remaining portion of the DNN is processed where more computing resources are available, such as in the cloud. This paper presents a novel lightweight compression technique designed specifically to quantize and compress the features output by the intermediate layer of a split DNN, without requiring any retraining of the network weights. Mathematical models for estimating the clipping and quantization error of ReLU and leaky-ReLU activations at this intermediate layer are developed and used to compute optimal clipping ranges for coarse quantization. We also present a modified entropy-constrained design algorithm for quantizing clipped activations. When applied to popular object-detection and classification DNNs, we were able to compress the 32-bit floating point intermediate activations down to 0.6 to 0.8 bits, while keeping the loss in accuracy to less than 1%. When compared to HEVC, we found that the lightweight codec consistently provided better inference accuracy, by up to 1.3%. The performance and simplicity of this lightweight compression technique makes it an attractive option for coding an intermediate layer of a split neural network for edge/cloud applications.

description: Designing and interpreting controlled experiments are important inquiry skills addressed in many current science curricula. The relevant skills associated with the design and interpretation of controlled experiments are summarised under the term control-of-variables strategy (CVS). Research on elementary school students’ CVS skills shows that they have basic conceptions of CVS, as they can correctly identify controlled experiments to test given hypotheses and can interpret the results of controlled experiments. However, they perform poorly when they have to plan experiments and interpret confounded experiments. Furthermore, previous research has identified eight misleading preconceptions regarding CVS that cause invalid experimental designs, called design errors. The current study investigates the occurrence and change of design errors during elementary school and their consistency over different tasks. Via a latent class analysis (LCA), we identified three distinct patterns of design errors: (1) correct CVS understanding, (2) change of too many variables and (3) non-contrastive experiments. Our results show that many students as low as grade two have a basic understanding of CVS and that occurring design errors are associated with limited metaconceptual knowledge about when and why to apply CVS. We discuss possible implications of our findings for teaching CVS and further research.

description: В статье рассматривается правовая природа полномочий Генерального прокурора Российской Федерации в уголовном судопроизводстве. Несмотря на большое количество научных работ, посвященных изучению различных аспектов деятельности прокурора в уголовном процессе, непосредственно полномочия Генерального прокурора РФ не исследовались. Цель исследования – обобщение и классификация уголовно-процессуальных полномочий Генерального прокурора РФ. Задача статьи – определить специфику полномочий Генерального прокурора РФ в уголовном судопроизводстве, выявить их отличия от полномочий всех иных нижестоящих прокуроров. Исследование базируется на методе структурно-функционального анализа, в соответствии с которым все явления изучаются с учетом системных закономерностей. Также применялись методы анализа и синтеза, индукции и дедукции, а также формально-юридический метод. В результате произведена классификация полномочий Генерального прокурора РФ. Все полномочия объединены в 3 группы: 1) полномочия вышестоящего прокурора; 2) исключительные процессуальные полномочия, имеющие уголовно-процессуальную природу и принадлежащие только Генеральному прокурору РФ; 3) экстраординарные полномочия, имеющие комплексную межотраслевую природу (обращение с представлениями о лишении неприкосновенности).
description: The article describes the legal nature of the powers of the Prosecutor General of the Russian Federation in criminal proceedings. Despite a considerable amount of scientific work on the study of various aspects of the prosecutor’s activities in criminal proceedings, the powers of the Prosecutor General were not investigated closely. The purpose of the article is to summarize and classify the criminal procedure powers of the Prosecutor General. The article aims to clarify the specifics of the powers of the Prosecutor General in criminal proceedings, their difference from the powers of all other inferior prosecutors. The study is based on the method of structural-functional analysis, according to which all phenomena are studied in connection with systemic laws. Methods such as analysis and synthesis, induction and deduction, and formal legal method were also used. As a result, the powers of the Prosecutor General were classified. All powers are summarized into three groups: a) the powers of a superior prosecutor; b) exclusive procedural powers, having a criminal procedure nature and belonging only to the Prosecutor General; c) extraordinary powers, having a complex intersectoral nature (handling ideas about deprivation of immunity).
