description: For any right-angled Coxeter group $Γ$ on $k$ generators, we construct proper actions of $Γ$ on $\mathrm{O}(p,q+1)$ by right and left multiplication, and on the Lie algebra $\mathfrak{o}(p,q+1)$ by affine transformations, for some $p,q\in\mathbb N$ with $p+q+1=k$. As a consequence, any virtually special group admits proper affine actions on some $\mathbb R^n$: this includes e.g. surface groups, hyperbolic 3-manifold groups, examples of word hyperbolic groups of arbitrarily large virtual cohomological dimension, etc. We also study some examples in cohomological dimension two and four, for which the dimension of the affine space may be substantially reduced.

description: Transport of molecules across membrane channels is investigated theoretically using exactly solvable one-dimensional discrete-state stochastic models. An interaction between molecules and membrane pores is modeled via a set of binding sites with different energies. It is shown that the interaction potential strongly influences the particle currents as well as fluctuations in the number of translocated molecules. For small concentration gradients the attractive sites lead to largest currents and fluctuations, while the repulsive interactions yield the largest fluxes and dispersions for large concentration gradients. Interaction energies that lead to maximal currents and maximal fluctuations are the same only for locally symmetric potentials, while they differ for the locally asymmetric potentials. The conditions for the most optimal translocation transport with maximal current and minimal dispersion are discussed. It is argued that in this case the interaction strength is independent of local symmetry of the potential of mean forces. In addition, the effect of the global asymmetry of the interaction potential is investigated, and it is shown that it also strongly affects the particle translocation dynamics. These phenomena can be explained by analyzing the details of the particle entering and leaving the binding sites in the channel.

description: We studied the deployment of computer-readable privacy policies encoded using the standard W3C Platform for Privacy Preferences (P3P) format to inform questions about P3P’s usefulness to end users and researchers. We found that P3P adoption is increasing overall and that P3P adoption rates greatly vary across industries. We found that P3P had been deployed on 10% of the sites returned in the top-20 results of typical searches, and on 21% of the sites returned in the top-20 results of e-commerce searches. We examined a set of over 5,000 web sites in both 2003 and 2006 and found that P3P deployment among these sites increased over that time period, although we observed decreases in some sectors. In the Fall of 2007 we observed 470 new P3P policies created over a two month period. We found high rates of syntax errors among P3P policies, but much lower rates of critical errors that prevent a P3P user agent from interpreting them.We also found that most P3P policies have discrepancies with their natural language counterparts. Some of these discrepancies can be attributed to ambiguities, while others cause the two policies to have completely different meanings. Finally, we show that the privacy policies of P3P-enabled popular websites are similar to the privacy policies of popular websites that do not use P3P.

description: When users handle large amounts of data, errors are hard to notice. Outlier finding is a new way to reduce errors by directing the user's attention to inconsistent data which may indicate errors. We have implemented an outlier finder for text, which can detect both unusual matches and unusual mismatches to a text pattern. When integrated into the user interface of a PBD text editor and tested in a user study, outlier finding substantially reduced errors.

description: The standard Wojtkowski-Markarian-Donnay-Bunimovich technique for the hyperbolicity of focusing or mixed billiards in the plane requires the diameter of a billiard table to be of the same order as the largest ray of curvature along the focusing boundary. This is due to the physical principle that is used in the proofs, the so-called defocusing mechanism of geometrical optics. In this paper we construct examples of hyperbolic billiards with a focusing boundary component of arbitrarily small curvature whose diameter is bounded by a constant independent of that curvature. Our proof employs a nonstardard cone bundle that does not solely use the familiar dispersing and defocusing mechanisms.

Evaluation of Component-Based Finite Element Method for Seismic Braced Frame Connections

Publisher: name: University of Illinois at Chicago
Year: 2024

description: In a steel structure, joints determine almost 50% of the total costs (Bijlaard & Brekelmans, 2008). This percentage of the total cost can drastically decrease if some details are avoided, like stiffeners (Navarro Villagómez, 2017). To eliminate these components, the most profound analysis of the joint is required, which will strengthen seamless workflows and increase productivity and safety in construction projects. IDEA StatiCa, introduced to the engineering world in 2014, is currently amongst one of the most revolutionary methods used for analyzing and designing a wide range of steel connections, ranging from commonly used standard connections to the most complex ones. Hence offering significant advantages in terms of time-saving, productivity, and safety in steel structure construction.
 This research was focused on evaluating four standard examples of Ordinary and Special Concentrically Braced Frames as per American Seismic Design Provisions, which are based on the uniform force method in CBFEM using IDEA StatiCa V23. All the limits states that are involved in a connection design are covered for each example. Also, an attempt to demonstrate efficient connection modeling has been made, which plays a pivotal role in analysis and design. It also involved performing several parametric studies to understand several limit states for parameter variation in detail.
 Overall, CBFEM gives approximately similar results when compared with AISC values, but slightly on the higher or lower side, depending on the type of concentrically braced frame and the type of analysis (i.e., stress-strain analysis, capacity design, etc.) used in CBFEM. It can also accurately predict the sequence of the occurrence of limit states concerning all the performed steel connections, similar to that predicted as per AISC Design. CBFEM can potentially be used as an analysis and design tool for the steel structure connection in high seismic zones of the United States.

Estimating the parameters from the power, we find generalizations of the PowerFlux method. Using simulated elliptically polarized signals injected into Gaussian noise, we apply the generalized methods to estimate the squared amplitudes of the plus and cross polarizations (and, in the most general case, the polarization angle), and test the relative detection efficiencies of the various methods.

Genealogías futuras: memoria y anticipación en la ficción especulativa Latinoamericana contemporánea
Creators: name: Parisi, Ariela
Publisher: name: No Publisher Supplied
Year: 2025

description: What is the role of collective memory when imagining communal futures? To answer this question, my dissertation takes on contemporary cultural expressions from Latin America–performances, films, and novels–that engage in what I term retro-speculation: they revisit the past in search of knowledge needed to formulate alternative visions of the future. My dissertation’s main argument is that cultural future-building practices in Latin America are intrinsically linked to the region's dictatorial history, and they also challenge the notion of time as linear and its association with neoliberal progress. I focus on narratives that envision an emancipatory future for generating public policies regarding environmental sustainability and the protection of marginalized people’s rights.My research pushes against existing boundaries in Latin American Memory Studies and Dictatorship Studies, expanding these fields by forging innovative connections between memory practices and speculative fiction. Interlinking these disciplines holds particular significance in the present historical juncture, characterized by the rise of far-right movements and a pervasive sense of apprehension about Latin America's future, where the role of the arts, humanities and public culture is facing scrutiny. My corpus is a gathered collection of materials from Argentina, Chile, Brazil, Colombia, and Guatemala, where brutal dictatorships and their neoliberal agendas between 1970 and 1990 resulted in grave consequences for minoritized populations, afro-descendants, and indigenous peoples. I highlight how these works reveal links between the dictatorial neoliberal past and the visions of the future while amplifying the voices of these marginalized Latin American communities. These radical futures offer a compelling alternative to the dominant narrative that equals economic progress to extractivism and that has been responsible for environmental degradation and human rights crises.

description: Once a baseline level of full automation is possible for an Automated Highway System, there are numerous choices to be made in deploying enhanced capabilities to improve safety, throughput, and travel time. Identifying a set of orthogonal capabilities enables describing multiple deployment paths within a common framework. Sixteen AHS configurations can be formed from a proposed set of orthogonal capabilities including: number of vehicles grouped into an entity (free agent vs. platoon), number of automated lanes (single or multiple), obstacle strategy (exclusion or detection), and system vigilance (trusting or vigilant). This systematic approach reveals a maximally enhanced end-state configuration: a platooned, multi-lane, obstacle detecting, vigilant AHS that could be attained using any of 24 incremental deployment paths. A mapping technique is presented that can assist in risk management by depicting alternative deployment paths and constraints within a single framework.

description: A recent proposal relates two dimensional holographic conformal field theories deformed by the integrable $T\bar{T}$ flow to AdS$_3$ with a finite radial cutoff. We investigate this proposal by studying perturbative correlation functions on the two sides. For low point correlators of the stress tensor, we successfully match the deformed CFT results at large central charge to bulk results obtained in classical pure gravity. The deformed CFT also provides definite predictions for loop corrections in the bulk. We then include matter fields in the bulk. To reproduce the classical bulk two-point function of a scalar operator we show that the deformed CFT needs to be augmented with double trace scalar operators, with the $T\bar{T}$ operator yielding corrections corresponding to loops in the bulk.

description: This paper presents optimizations for verifying systems with complex time-invariant constraints. These constraints arise naturally from modeling physical systems, e.g., in establishing the relationship between different components in a system. To verify constraint-rich systems, we propose two new optimizations. The first optimization is a simple, yet powerful, extension of the conjunctivepartitioning algorithm. The second is a collection of BDD-based macro-extraction and macro-expansion algorithms to remove state variables. We show that these two optimizations are essential in verifying constraint-rich problems; in particular, this work has enabled the verification of fault diagnosis models of the Nomad robot (an Antarctic meteorite explorer) and of the NASA Deep Space One spacecraft.

description: The genus Trigonotodus was originally described from the Eocene of Kazakhstan and has since been recorded from the Eocene of Uzbekistan, England and Morocco as well as the Oligocene of South Carolina. To date, no occurrences of the genus have been recognized from the Eocene of North America. Here we report on three teeth of Trigonotodus cf. tusbairicus collected in Monmouth County, New Jersey from a lag deposit separating the middle Eocene Shark River Formation and the early Miocene Kirkwood Formation. These specimens are referred to the Shark River Formation and are the first examples of the genus to be reported from the Eocene of North America.
Modeling Ultraviolet Wind Line Variability in Massive Hot Stars

description: We model the detailed time-evolution of Discrete Absorption Components (DACs) observed in P Cygni profiles of the Si IV lam1400 resonance doublet lines of the fast-rotating supergiant HD 64760 (B0.5 Ib). We adopt the common assumption that the DACs are caused by Co-rotating Interaction Regions (CIRs) in the stellar wind. We perform 3D radiative transfer calculations with hydrodynamic models of the stellar wind that incorporate these large-scale density- and velocity-structures. We develop the 3D transfer code Wind3D to investigate the physical properties of CIRs with detailed fits to the DAC shape and morphology. The CIRs are caused by irregularities on the stellar surface that change the radiative force in the stellar wind. In our hydrodynamic model we approximate these irregularities by circular symmetric spots on the stellar surface. We use the Zeus3D code to model the stellar wind and the CIRs, limited to the equatorial plane. We constrain the properties of large-scale wind structures with detailed fits to DACs observed in HD 64760. A model with two spots of unequal brightness and size on opposite sides of the equator, with opening angles of 20 +/- 5 degr and 30 +/- 5 degr diameter, and that are 20 +/- 5 % and 8 +/- 5 % brighter than the stellar surface, respectively, provides the best fit to the observed DACs. The recurrence time of the DACs compared to the estimated rotational period corresponds to spot velocities that are 5 times slower than the rotational velocity. The mass-loss rate of the structured wind model for HD 64760 does not exceed the rate of the spherically symmetric smooth wind model by more than 1 %. The fact that DACs are observed in a large number of hot stars constrains the clumping that can be present in their winds, as substantial amounts of clumping would tend to destroy the CIRs.

description: Modular Origami Robots (MORs) offer adaptable morphology through foldable units, enabling shape reconfiguration. Each structural variation demands new control strategies, making manual programming inefficient and impractical. The study outlines an automated framework to evolve neural network controllers using evolutionary algorithms in simulation. Controllers evolved within the PyBullet engine via Pyrosim, across two MOR morphologies: a Three-Cubed Robot and a quadruped. Implemented and compared three algorithms: Random Search (RS), Hill Climber (HC), and Parallel Hill Climber (PHC). Performance metrics included locomotion speed, energy efficiency, gait stability, and adaptability across terrains. The Parallel Hill Climber achieved the highest speed (0.3 m/s), lowest energy usage (15.0 AU/m), and fastest convergence, outperforming all other algorithms (RS and HC) across both robot morphologies (Three-Cubed Robot and Quadruped Robot). Quadrupeds evolved stable, natural-like trotting behaviors, while even the minimal three-cube robot achieved forward locomotion via learned coordination. The evolved neural controllers generalized to unseen environments without retraining, demonstrating transferability and robustness. No prior knowledge or manual tuning was required, proving that evolutionary optimization can autonomously generate effective, morphology-aware control policies. The findings suggest that an embodied AI approach produce adaptive behavior in MORs. The approach shows promise for developing robots that operate in unstructured settings (e.g., search-and-rescue or space exploration) without extensive manual reprogramming.

Search for Standard Model Higgs Bosons Produced in Association with W Bosons

description: We report on the results of a search for standard model Higgs bosons produced in association with W bosons from p-pbar collisions at root s = 1.96 TeV. The search uses a data sample corresponding to approximately 1 fb-1 of integrated luminosity. Events consistent with the W to l-nu and H to b-bbar signature are selected by triggering on a high-pT electron or muon candidate and tagging one or two of the jet candidates as having originated from b quarks. A neural network filter rejects a fraction of tagged charm and light flavor jets, increasing the b-jet purity in the sample and thereby reducing the background to Higgs boson production. We observe no excess l-nu-b-bbar production beyond the background expectation, and we set 95% confidence level upper limits on the production cross section times branching fraction sigma(p-pbar to WH) times Br(H to b-bbar) ranging from 3.9 to 1.3 pb, for specific Higgs boson mass hypotheses in the range 110 to 150 GeV/c2, respectively.

description: Learning to rank is becoming an increasingly popular research area in machine learning. The ranking problem aims to induce an ordering or preference relations among a set of instances in the input space. However, collecting labeled data is growing into a burden in many rank applications since labeling requires eliciting the relative ordering over the set of alternatives. In this paper, we propose a novel active learning framework for SVM-based and boosting-based rank learning. Our approach suggests sampling based on maximizing the estimated loss differential over unlabeled data. Experimental results on two benchmark corpora show that the proposed model substantially reduces the labeling effort, and achieves superior performance rapidly with as much as 30% relative improvement over the margin-based sampling baseline.

description: This paper describes a method for observing maneuvering targets using a group of mobile robots equipped with video cameras. These robots are part of a team of small-size (7x7x7 cm) robots configured from modular components that collaborate to accomplish a given task. The cameras seek to observe the target while facing it as much as possible from their respective viewpoints. This work considers the problem of scheduling and maneuvering the cameras based on the evaluation of their current positions in terms of how well can they maintain a frontal view of the target. We describe our approach, which distributes the task among several robots and avoids extensive energy consumption on a single robot. We explore the concept in simulation and present results.

description: We present results of our large area survey for z'-band dropout galaxies at z = 7 in a 1568 arcmin2 sky area covering the SDF and GOODS-N fields. Combining our ultra-deep Subaru/Suprime-Cam z'- and y-band (λeff = 1 μm) images with legacy data of Subaru and Hubble Space Telescope, we have identified 22 bright z-dropout galaxies down to y = 26, one of which has a spectroscopic redshift of z = 6.96 determined from Lyα emission. The z = 7 luminosity function yields the best-fit Schechter parameters of ϕ* = 0.69+2.62−0.55 × 10−3 Mpc−3, M*UV = −20.10 ±  0.76 mag, and α = −1.72 ± 0.65, and indicates a decrease from z = 6 at a >95% confidence level. This decrease is beyond the cosmic variance in our two fields, which is estimated to be a factor of ≲2. We have found that the cosmic star formation rate density drops from the peak at z = 2–3 to z = 7 roughly by a factor of ∼10 but not larger than ∼100. A comparison with the reionization models suggests either that the universe could not be totally ionized by only galaxies at z = 7, or more likely that properties of galaxies at z = 7 are different from those at low redshifts having, e.g., a larger escape fraction (≳0.2), a lower metallicity, and/or a flatter initial mass function. Our SDF z-dropout galaxies appear to form 60 Mpc long filamentary structures, and the z = 6.96 galaxy with Lyα emission is located at the center of an overdense region consisting of four UV bright dropout candidates, which might suggest an existence of a well-developed ionized bubble at z = 7.

No evidence for the production of such particles was observed in topologies involving jets and missing transverse energy, and 95% C.L. lower limits of 379 GeV and 308 GeV were set on the squark and gluino masses, respectively, within the framework of minimal supergravity with tan(beta)=3, A0=0, and mu<0. The corresponding previous limits are improved by 54 GeV and 67 GeV.

The integration of these modules can be further simplified by the use of a high-level programming interface. We have developed Onika, an iconically programmed human-machine interface, to interact with a reconfigurable software framework to create reusable code. Onika presents appropriate work environments for both application engineers and end-users. For engineers, icons representing real-time software modules can be combined to form real-time jobs. For the end-user, icons representing these jobs are assembled by the user into applications. Onika verifies that all jobs and applications are syntactically correct, non-ambiguous, and complete. They can then be executed from within Onika, or can be saved as a stand-alone program which can be executed independently on the underlying real-time operating system. Onika has been fully integrated with the Chimera real-time operating system in order to control several different robotic systems in the Advanced Manipulators Laboratory at Carnegie Mellon University.

description: This paper presents a methodology for deriving the system graph of a 3D mechanism from CAD models. That is, a linear graph that captures the energy flow in a system. This work is part of a larger research effort incomposable simulation. Incomposable simulation, CAD models of system components are augmented with simulation models describing the component’s dynamic behavior indifferent energy domains. By composable simulation we mean then the ability to automatically generate system-level simulations through composition of individual component models. From the system graph, the system-level dynamic equations can be derived independently of the underlying energy domains.

description: The LAB4D is a new application-specific integrated circuit (ASIC) of the Large Analog Bandwidth Recorder and Digitizer with Ordered Readout (LABRADOR) family, for use in direct wideband radio frequency digitization such as is used in ultrahigh energy neutrino and cosmic ray astrophysics. The LAB4D is a single channel switched-capacitor array (SCA) 12-bit sampler with integrated analog-to-digital converters (ADC), developed in the TSMC 0.25um process. The LAB4D, operating at 3.2GSa/s, contains 4096 total samples arranged in 32 windows, for a total record length of 1280ns. The 3dB bandwidth is approximately 1.3GHz, with a directly-coupled 50ohm input. This represents a factor of 16 increase in the sample depth and an increase in analog bandwidth and sampling depth in comparison to the previous generation LAB3 digitizer. Individually addressable windows allow for sampling and digitization to occur simultaneously, leading to nearly deadtime-free readout for kHz readout rates. All biases and current references are generated via internal digital-to-analog converters (DACs), resulting in a stand-alone digitizer with no additional support circuitry. In addition, the LAB4D contains sample cell timebase trimming capabilities, reducing the intrinsic sample-to-sample time variance to less than 5ps; an improvement of about 80%. This allows the LAB4D to be used in precision timing applications with minimal post-hoc calibration.

description: TCP is the most widely used transport protocol in the internet. However, it offers suboptimal performance when operating over high bandwidth mmWave links. The main issues introduced by communications at such high frequencies are (i) the sensitivity to blockage and (ii) the high bandwidth fluctuations due to Line of Sight (LOS) to Non Line of Sight (NLOS) transitions and vice versa. In particular, TCP has an abstract view of the end-to-end connection, which does not properly capture the dynamics of the wireless mmWave link. The consequence is a suboptimal utilization of the available resources. In this paper we propose a TCP proxy architecture that improves the performance of TCP flows without any modification at the remote sender side. The proxy is installed in the Radio Access Network, and exploits information available at the gNB in order to maximize throughput and minimize latency.

Revealing the quantitative relation between simultaneous correlations in complementary bases and quantum steering for two-qubit Bell diagonal states

description: The present work is motivated by the question as to what aspect of correlation entailed by the two-qubit state serves as the appropriate quantitative resource for steering. To this end, considering Bell-diagonal states, suitable measures of simultaneous correlations in two and three complementary (mutually unbiased) bases are identified as the relevant resources for quantum steering. Quantitative relations between appropriate measures of quantum steering and the corresponding measures of simultaneous correlations in complementary bases are demonstrated which ensure that for two qubit steerable Bell-diagonal states, higher value of simultaneous correlations in mutually unbiased bases necessarily implies higher degree of quantum steering, both for two and three setting steering scenarios.

description: We identified globular clusters and field stars of extragalactic origin and investigated their chemical, physical, and kinematical properties. This objects as supposed was captured by the Galaxy at different times from debris of the dwarf satellite galaxies disrupted by its tidal forces. The results are follows. (1) The majorities of metal-poor stellar objects in the Galaxy have an extragalactic origin. (2) The masses of the accreted globular clusters decrease with the removal from the center and the plane of the Galaxy. (3) The relative abundances of chemical elements in the accreted and genetically connected stars are essentially distinguished. (4) The accreted field stars demonstrate the decrease of the relative magnesium abundanses with an increase in sizes and inclinations of their orbits. (5) The stars of the Centaurus moving group were born from the matter, in which star formation rate was considerably lower than in the early Galaxy. On the base of these properties was made a conclusion that with the decrease of the masses of the dwarf galaxies in them simultaneously decrease the average masses of globular clusters and the maximum masses of supernova SNe II. Namely latter fact leads to the decrease of the relative abundances of α-elements in their metal-poor stars.

Holographic Dark Energy in Braneworld Models with a Gauss-Bonnet Term in the Bulk. Interacting Behavior and the w =-1 Crossing

description: We apply bulk holographic dark energy in general braneworld models with a Gauss-Bonnet term in the bulk and an induced gravity term and a perfect fluid on the brane. Without making any additional assumptions we extract the Friedmann equation on the physical brane and we show that a $ρ$-$ρ_Λ$ coupling arises naturally by the full 5D dynamics. The low-energy (late-time) evolution reveals that the effective 4D holographic dark energy behaves as ``quintom'', that is it crosses the phantom divide $w=-1$ during the evolution. In particular, the Gauss-Bonnet contribution decreases the present value of $w_Λ$, while it increases the growing rate of $w_Λ(z)$ with $z$, in comparison with the case where such a term is absent.

The Three-body Force and the Tetraquark Interpretation of Light Scalar Mesons

description: We study the possible tetraquark interpretation of light scalar meson states $a_0(980)$, $f_0(980)$, $κ$, $σ$ within the framework of the non-relativistic potential model. The wave functions of tetraquark states are obtained in a space spanned by multiple Gaussian functions. We find that the mass spectra of the light scalar mesons can be well accommodated in the tetraquark picture if we introduce a three-body quark interaction in the quark model. Using the obtained multiple Gaussian wave functions, the decay constants of tetraquarks are also calculated within the ``fall apart'' mechanism.
Micro-XRD Investigation of Phase Formation During Setting of MTA Flow™
Creators: name: Grandin, Harley
Publisher: name: University of Illinois at Chicago

description: MTA’s success in endodontics in combination with its inherent drawbacks have led to the development of countless derivatives. In vitro testing, specifically Micro‐X‐ray diffraction analysis (XRD), allows for efficient preliminary characterization of novel bioceramics and their proprietary mixes. Identifying phases thought to be responsible for MTA’s bioactivity through XRD provides insight into new materials’ efficacy. Methods: Ten human third molars were sectioned axially using a diamond saw (Isomet, Buehler). Three 3mm by 3mm cylindrical preparations were made in dentin to simulate root end preparations. MTA Flow™ (Ultradent) was injected into the preparations. The filled tooth-slot specimens were placed in simulated body fluid to maintain 100% humidity for three months. Micro-XRD patterns were obtained from the surface of MTA Flow™ after filling, 2hr, 4hr, 12hr, 1 day, 7 days, 1 month, and 3 months. The International Centre for Diffraction Data pure powder standards was referenced to index peaks for phase identification. The goodness-of-fit for the peak positions was compared. Micro-XRD patterns demonstrated continuous phase (di/tricalcium silicates) transformation up to 24 hours. Subsequently, the patterns stabilized, with little differences in the phases present from the 1-week to 3-month periods. The major final phases appeared to be tricalcium silicate, tricalcium aluminate and bismuth oxide. Conclusions: Use of the propitiatory gel accelerates the setting reaction of MTA Flow™ for the first 24-hour period, as evidenced by early crystalline phase formation. Some phases that formed during the first 24 hours became less evident at longer time periods.
