On rich points and incidences with restricted sets of lines in 3-space
Creators: name: Sharir, Micha

Publisher: name: Journal of Computational Geometry
Year: 2022

description: Let $L$ be a set of $n$ lines in $\mathbb{R}^3$ that is contained, when represented as points in the four-dimensional Plücker space of lines in $\mathbb{R}^3$, in an irreducible variety $T$ of constant degree which is non-degenerate with respect to $L$ (see below). We show: (1) If $T$ is two-dimensional, the number of $r$-rich points (points incident to at least $r$ lines of $L$) is $O(n^{4/3+\varepsilon}/r^2)$, for $r \ge 3$ and for any $\varepsilon > 0$, and, if at most $n^{1/3}$ lines of $L$ lie on any common regulus, there are at most $O(n^{4/3+\varepsilon})$ $2$-rich points. For $r$ larger than some sufficiently large constant, the number of $r$-rich points is also $O(n/r)$. As an application, we deduce (with an $\varepsilon$-loss in the exponent) the bound obtained by Pach and de Zeeuw (2017) on the number of distinct distances determined by $n$ points on an irreducible algebraic curve of constant degree in the plane that is not a line nor a circle. (2) If $T$ is two-dimensional, the number of incidences between $L$ and a set of $m$ points in $\mathbb{R}^3$ is $O(m + n)$. (3) If $T$ is three-dimensional and nonlinear, the number of incidences between $L$ and a set of $m$ points in $\mathbb{R}^3$ is $O(m^{3/5}n^{3/5} + (m^{11/15}n^{2/5} + m^{1/3}n{2/3})s^{1/3} + m + n)$, provided that no plane contains more than $s$ of the points. When $s = O(\min \{ n{3/5}/m^{2/5}, m^{1/2} \})$, the bound becomes $O(m^{3/5}n^{3/5} + m + n)$. As an application, we prove that the number of incidences between $m$ points and $n$ lines in $\mathbb{R}^4$ contained in a quadratic hypersurface (which does not contain a hyperplane) is $O(m^{3/5}n^{3/5} + m + n)$. The proofs use, in addition to various tools from algebraic geometry, recent bounds on the number of incidences between points and algebraic curves in the plane.

description: We introduce Sinyukov-like tensors, a special kind of conformal Killing tensors. In Robertson-Walker space-times they have the perfect-fluid form and only depend on two constants and the scale factor. They are the candidate for the dark term of the newly proposed Conformal Killing Gravity, by Harada. In addition to ordinary matter, the Friedmann equations contain a dark term and a Lambda term that parametrize the Sinyukov-like tensor. The expression of H(z) is tested on cosmological data based on cosmic chronometers CC or including baryon acoustic oscillations BAO. There is a large incertitude in Omega_Lambda and Omega_dark that may become negative, but their sum is close to Omega_Lambda of Lambda-CDM. In any case, there is a future singularity, that is a big rip for all Omegas positive. We solve the equation for the evolution, in linear approximation, of the density contrast in matter-dominated universe. The dark sector and the Lambda term give no significative deviation from Lambda-CDM and GR results.

Algorithms for approximate sparse regression and nearest induced hulls
Creators: name: Cardinal, Jean
name: Ooms, Aurélien
Publisher: name: Journal of Computational Geometry
Year: 2022

description: The sparse regression problem, also known as best subset selection problem, can be cast as follows: Given a set $S$ of $n$ points in $\mathbb{R}^d$, a point $y\in\mathbb{R}^d$, and an integer $2 \leq k \leq d$, find an affine combination of at most $k$ points of $S$ that is nearest to $y$. We describe a $O(n^{k-1} \log^{d-k+1} n)$-time randomized $(1+\varepsilon)$-approximation algorithm for this problem with $d$ and $\varepsilon$ constant. This is the first algorithm for this problem running in time $o(n^k)$. Its running time is similar to the query time of a data structure recently proposed by Har-Peled, Indyk, and Mahabadi (ICALP'18), while not requiring any preprocessing. Up to polylogarithmic factors, it matches a conditional lower bound relying on a conjecture about affine degeneracy testing. In the special case where $k = d = O(1)$, we also provide a simple $O(n^{d-1+\delta})$-time deterministic exact algorithm, for any $\delta > 0$. Finally, we show how to adapt the approximation algorithm for the sparse convex regression problems with the same running time, up to polylogarithmic factors.

We provide an algorithmically testable set of conditions which, if satisfied, imply the existence of a constant $B_{C, q}$ such that if $n > B_{C,q}$, there are no solutions $(x, y, z, n)$ of the equation. Our methods use the modular method for Diophantine equations, along with level lowering and Galois theory.

description: Deep learning algorithms will play a key role in the upcoming runs of the Large Hadron Collider (LHC), helping bolster various fronts ranging from fast and accurate detector simulations to physics analysis probing possible deviations from the Standard Model. The game-changing feature of these new algorithms is the ability to extract relevant information from high-dimensional input spaces, often regarded as "replacing the expert" in designing physics-intuitive variables. While this may seem true at first glance, it is far from reality. Existing research shows that physics-inspired feature extractors have many advantages beyond improving the qualitative understanding of the extracted features. In this review, we systematically explore automatic feature extraction from a phenomenological viewpoint and the motivation for physics-inspired architectures. We also discuss how prior knowledge from physics results in the naturalness of the point cloud representation and discuss graph-based applications to LHC phenomenology.

description: Fluctuations affect the functionality of nanodevices. Thermodynamic uncertainty relations (TURs), derived within the framework of stochastic thermodynamics, show that a minimal amount of dissipation is required to obtain a given relative energy current dispersion, that is, current precision has a thermodynamic cost. It is therefore of great interest to explore the possibility that TURs are violated, particularly for quantum systems, leading to accurate currents at lower cost. Here, we show that two quantum harmonic oscillators are synchronized by coupling to a common thermal environment, at strong dissipation and low temperature. In this regime, periodically modulated couplings to a second thermal reservoir, breaking time-reversal symmetry and taking advantage of non-Markovianity of this latter reservoir, lead to strong violation of TURs for local work currents, while maintaining finite output power. Our results pave the way for the use of synchronization in the thermodynamics of precision.

description: We introduce a new class of two dimensional gravity models using ideas motivated by the Teleparallel Equivalent of General Relativity. This leads to a rather natural formulation of a theory that has close links with Jackiw-Teitelboim gravity. After introducing the theory and discussing its vacuum solutions, we present the Hamiltonian analysis. This implies the presence of a single dynamical degree of freedom, which is in sharp contrast to General Relativity, where there are no degrees of freedom in two spacetime dimensions. Our approach can be extended to various other lower-dimensional gravity theories and thus could be of wider interest.

description: Tropical forests compose only one third of the global forest estate, but are critical to maintaining biodiversity, abating climate change, and sustaining human livelihoods. Yet, tropical forests are among the most rapidly vanishing biomes on the planet. From the dry forests of the South American Chaco to the tropical moist lowland forests of South-East Asia, tropical forests experience intense pressure from deforestation and forest degradation, and are thus at the center of global conservation initiatives. Yet, tropical moist and dry forests are important in different ways, making their reliable distinction crucial. For example, whereas tropical moist forests harbor disproportionately large portions of species and living carbon stores, tropical dry forests sustain the livelihoods of hundreds of millions people worldwide, regulating freshwater water supplies and delivering other ecosystem services in the world’s drylands. Despite their important, but distinct roles for global sustainability and their exposure to extreme threats, there is a surprising scarcity of data enabling a reliable distinction of these biomes, or a reliable quantification of their respective long-term change rates. Global assessments largely rely on overlays between generic forest-change maps and coarse biome masks. Tropical dry forests dynamics have a particularly poor documentation, with strong disagreements between available maps of tropical dry-forest extents, and no reliable data on long-term global changes.
 We will present the first global wall-to-wall data product distinguishing annual spatial extents and changes of tropical moist and dry forests at 300-m resolution back into the early 1990s – a period of adamant importance for tropical forest monitoring, as it marks peaks in both tropical and dry forest losses in several regions worldwide. We developed this product by hindcasting Hansen et al.’s Global Forest Change (GFC) time-series using a multi-scale, spatially and temporally explicit machine learning approach and fusing multiple remote sensing products derived with different satellite sensors. We built our predictive model with more than 600,000 samples, collected systematically in every country to reflect regional differences in forest-management practices and long-term change patterns and drivers. We performed a spatially explicit cross-validation, including a comparison with yearly, high-resolution forest cover data mapped by an independent dataset. Moreover, we collated over 500,000 field plots distinguishing moist and dry tropical forests to infer local boundaries between the two forest types. Our historical forest mapping approach achieved high performance accuracies (R=0.90 RMSE=9.78%), while our forest classification approach performed similarly well in distinguishing tropical moist forest (F1-score=0.91) and tropical dry forest (F1-score=0.92).

description: We construct an off-shell $\mathcal{N}=2$ superconformal cubic vertex for the hypermultiplet coupled to an arbitrary integer higher spin ${\bf s}$ gauge $\mathcal{N}=2$ supermultiplet % in flatfour-dimensional space. in a general $\mathcal{N}=2$ conformal supergravity background. We heavily use $\mathcal{N}=2, 4D$ harmonic superspace that provides an unconstrained superfield Lagrangian description. We start with $\mathcal{N}=2$ global superconformal symmetry transformations of the free hypermultiplet model and require invariance of the cubic vertices of general form under these transformations and their gauged version. As a result, we deduce $\mathcal{N}=2, 4D$ unconstrained analytic superconformal gauge potentials for an arbitrary integer ${\bf s}$. These are the basic ingredients of the approach under consideration. We describe the properties of the gauge potentials, derive the corresponding superconformal and gauge transformation laws, and inspect the off-shell contents of the thus obtained $\mathcal{N}=2$ superconformal higher-spin ${\bf s}$ multiplets in the Wess-Zumino gauges. The spin ${\bf s}$ multiplet involves $8(2{\bf s} -1)_B + 8(2{\bf s}-1)_F$ essential off-shell degrees of freedom. The cubic vertex has the generic structure higher spin gauge superfields $\times$ hypermultiplet supercurrents. We present the explicit form of the relevant supercurrents.

description: We reconsider the derivation of Ward identities for spin stiffnesses, which determine the non-linear sigma model of magnetic degrees of freedom of interacting electrons in the presence of antiferromagnetic or incommensurate correlations. We emphasize that in the approaches, which do not break explicitly spin symmetry of the action, the spatial components of gauge kernel, which is used to obtain spin stiffnesses, remain gauge invariant even in case of spontaneous spin symmetry breaking. We derive the corrected Ward identities, which account for this gauge invariance. We emphasize that the frequency dependence of temporal spin stiffnesses is not fixed by the obtained identities, and show that the infinitesimally small external staggered field is crucially important to obtain finite static uniform transverse susceptibility. On the other hand, we find that the spatial spin stiffnesses are determined by the gauge kernel of the Legendre transformed theory, which is in general {\it different} from the gauge kernel of the original theory and obtain an explicit expressions for spatial spin stiffnesses through susceptibilities and current correlation functions. We verify numerically the obtained results within dynamic mean field theory, and obtain doping dependencies of the resulting spin stiffnesses for antiferromagnetic and incommensurate phase.

description: The exploration of dark sector interactions via gravitational waves (GWs) from binary inspirals has been a subject of recent interest. We study dark forces using extreme mass ratio inspirals (EMRIs), pointing out two issues of interest. Firstly, the innermost stable circular orbit (ISCO) of the EMRI, which sets the characteristic length scale of the system and hence the dark force range to which it exhibits enhanced sensitivity, probes force mediator masses that complement those studied with supermassive black hole (SMBH) or neutron star binaries. The LISA mission (the proposed $μ$Ares detector) will probe mediators with masses $m_V \sim 10^{-16}~{\rm eV}$ ($m_V \sim 10^{-18}~{\rm eV}$), corresponding to ISCOs of $10^6 M_\odot$ ($10^8 M_\odot$) central SMBHs. Secondly, while the sensitivity to dark couplings is typically limited by the uncertainty in the binary component masses, independent mass measurements of the central SMBH through reverberation mapping campaigns or the motion of dynamical tracers enable one to break this degeneracy. Our results, therefore, highlight the necessity for coordinated studies, loosely referred to as "multimessenger", between future $μ{\rm Hz}-{\rm mHz}$ GW observatories and ongoing and forthcoming SMBH mass measurement campaigns, including OzDES-RM, SDSS-RM, and SDSS-V Black Hole Mapper.

The Effect Of Language Mixing on Word Retrieval in Bilingual Adults with Aphasia
Creators: name: Nichols, Meghan
Publisher: name: Digital Repository at the University of Maryland
Year: 2022
Subjects: subject: Speech therapy

description: Lexical retrieval deficits are a common feature in aphasia, and while much research has been done on bilingual aphasia and on the processes involved in language mixing by healthy bilingual adults, it is not clear whether it may be beneficial for bilingual people with aphasia to change languages in moments of lexical retrieval or if it is more effective to continue the lexical search in one language. The primary aim of this project was to determine whether bilingual people with aphasia demonstrate global and local effects of language mixing. Grammatical categories (i.e., nouns and verbs) were examined separately, and participant- and stimulus-related factors were considered. Based on preliminary analyses of participants’ accuracy and response onset latencies, it appears that participants tended to benefit from mixing in terms of speed and accuracy and that their results may be related to their language proficiency and dominance.

description: Bioassay-guided separation afforded furanodienone 1,10-epoxide (9) as the new compound, curcolone (10) as partially described compound and ten known compounds; germacrone (1), furanodienone (2), curzerenone (3), curcumenol (4), zederone (5), comosone II (6), (1E,4E,8R)-8-hydroxygermacra-1(10),4,7(11)-trieno-12,8-lactone (7), 13-hydroxygermacrone (8), curcuzederone (11) and demethoxycurcumin (12). The study showed that germacrone, furanodienone, curzerenone, comosone II, 13-hydroxygermacrone, curcuzederone and demethoxycurcumin are the bioactive compounds of C. aeruginosa rhizomes. Comosone II significantly inhibited MDA-MB-231 cell migration and invasion through the inhibition of MMP-9 enzyme. The present study may lead to further anticancer studies of comosone II and supports the traditional uses of C. aeruginosa rhizomes.

SOMTP: Self-Supervised Learning-Based Optimizer for MPC-Based Safe Trajectory Planning Problems in Robotics

description: Model Predictive Control (MPC)-based trajectory planning has been widely used in robotics, and incorporating Control Barrier Function (CBF) constraints into MPC can greatly improve its obstacle avoidance efficiency. Unfortunately, traditional optimizers are resource-consuming and slow to solve such non-convex constrained optimization problems (COPs) while learning-based methods struggle to satisfy the non-convex constraints. In this paper, we propose SOMTP algorithm, a self-supervised learning-based optimizer for CBF-MPC trajectory planning. Specifically, first, SOMTP employs problem transcription to satisfy most of the constraints. Then the differentiable SLPG correction is proposed to move the solution closer to the safe set and is then converted as the guide policy in the following training process. After that, inspired by the Augmented Lagrangian Method (ALM), our training algorithm integrated with guide policy constraints is proposed to enable the optimizer network to converge to a feasible solution. Finally, experiments show that the proposed algorithm has better feasibility than other learning-based methods and can provide solutions much faster than traditional optimizers with similar optimality.

description: Physical field modulation has been regarded as a promising approach to boost the performance of various electrocatalysts and has recently received notable attention. However, such a technique by coupling an external field to controllably enable efficient and green electrosynthesis of hydrogen peroxide (H2O2) through a 2e− oxygen reduction reaction (ORR) has not been perceived so far. In order to address the feasibility of this method, a controllable piezoelectric strategy based on the response of intrinsic electric domains to the stimulation of fluid mechanical force was exploited effectively to induce local electric fields on the polarized ceramic catalyst surface during the dynamic ORR. By adjusting the polarization degree of ceramic catalysts, the strength of the local electric field could be accordingly modulated, thus tuning the coverage of OH− ions on the catalyst surface which is beneficial for optimizing the binding strength towards oxygen-containing intermediates and alleviating the disproportionation of the peroxide product.
Strain effects on the electronic properties of a graphene wormhole

description: In this work, we explore the strain and curvature effects on the electronic properties of a curved graphene structure, called the graphene wormhole. The electron dynamics is described by a massless Dirac fermion containing position--dependent Fermi velocity. In addition, the strain produces a pseudo--magnetic vector potential to the geometric coupling. For an isotropic strain tensor, the decoupled components of the spinor field exhibit a supersymmetric (SUSY) potential, depending on the centrifugal term and the external magnetic field only. In the absence of a external magnetic field, the strain yields to an exponential damped amplitude, whereas the curvature leads to a power--law damping of the wave function. The spin--curvature coupling breaks the chiral symmetry between the upper and the lower spinor component, which leads to the increasing of the wave function on either upper or lower region of the wormhole, i.e., depending on the spin number. By adding an uniform magnetic field, the effective potential exhibits an asymptotic quadratic profile and a spin--curvature barrier near the throat. As a result, the bound states (Landau levels) are confined around the wormhole throat showing an asymmetric and spin--dependent profile.

description: Due to the widespread adoption of "work-from-home" policies, videoconferencing applications (e.g., Zoom) have become indispensable for remote communication. However, they often lack immersiveness, leading to the so-called "Zoom fatigue" and degrading communication efficiency. The recent debut of Apple Vision Pro, a mobile headset that supports "spatial persona", aims to offer an immersive telepresence experience. In this paper, we conduct a first-of-its-kind in-depth and empirical study to analyze the performance of immersive telepresence with Apple FaceTime, Cisco Webex, Microsoft Teams, and Zoom on Vision Pro. We find that only FaceTime provides a truly immersive experience with spatial personas, whereas others still operate 2D personas. Our measurement results reveal that (1) FaceTime delivers semantic data to optimize bandwidth consumption, which is even lower than that of 2D persona for other applications, and (2) it employs visibility-aware optimizations to reduce rendering overhead. However, the scalability of FaceTime remains limited, with a simple server-allocation strategy that potentially leads to high network delay for users.

description: Many econometric analyses include dependent variables which are constrained to the interval between zero and one. Under such circumstances simple regression procedures break down. The simple logit model is extended to the multi-factor case. Two alternative models are defined depending on the error structure. The generalized least squares approach assumes the share specification is an accurate representation of the underlying input demand structure. The multinomial maximum likelihood model treats the dependent variable as a probability with a multinomial density. Either model provides a wide array of functional forms while maintaining a straight-forward estimating procedure.
Propositional dynamic logic and asynchronous cascade decompositions for regular trace languages

description: We propose a local, past-oriented fragment of propositional dynamic logic to reason about concurrent scenarios modelled as Mazurkiewicz traces, and prove it to be expressively complete with respect to regular trace languages. Because of locality, specifications in this logic are efficiently translated into asynchronous automata, in a way that reflects the structure of formulas. In particular, we obtain a new proof of Zielonka's fundamental theorem and we prove that any regular trace language can be implemented by a cascade product of localized asynchronous automata, which essentially operate on a single process.
 These results refine earlier results by Adsul et al. which involved a larger fragment of past propositional dynamic logic and used Mukund and Sohoni's gossip automaton. Our new results avoid using this automaton, or Zielonka's timestamping mechanism and, in particular, they show how to implement a gossip automaton as a cascade product.
