description: In this paper, we summarize recent research results from a new technique of sensor calibration called Shape from Motion Calibration. We first present the basic technique, which is an eigenspace analysis, and show that it includes the rig- or of least squares without the full burden of measuring all the applied inputs. Next we present new research that removes another constraint of the calibration technique and extends the robustness to cover systems with slight nonlinearities.
A Social Justice Biology Curriculum to Strengthen Community College Students’ Critical Consciousness
Creators: name: Bernal-Munera, Marcela
Publisher: name: University of Illinois at Chicago
Year: 2024

description: The existing body of research presents two contrasting views of community colleges, one portraying them as a “second chance” for individuals, offering an accessible route to higher socioeconomic status. The second views community colleges as a deceptive cover designed to divert marginalized people away from prestigious colleges and to “blue-collar” occupations.
Drawing inspiration from Paulo Freire’s concept of critical consciousness, I propose a third perspective, a liberatory viewpoint. This approach involves offering an education that raises students’ awareness and empowers them to enact positive transformations in their lives. Looking to nurture critical consciousness in science majors, I infused the traditional biology curriculum with social justice issues in two Biology II sections at a community college in the Midwestern U.S. with an institutional focus on healthcare careers. Based on conversations with students, I selected issues directly connected to their communities and biology and healthcare as the core of three lesson plans: climate change and food apartheid, environmental justice, and biases and racism in science and healthcare. This study examined two questions. First, how do the affordances and challenges associated with integrating social justice issues relevant to science into the biology curriculum create possibilities for liberatory education in community colleges? The second addresses how community college students exhibit critical consciousness while demonstrating and integrating scientific understandings as they make meaning of social justice issues in a biology course. Critical race theory, critical consciousness, and justice-centered science pedagogy frameworks guided my exploration of the answers. The data suggested that despite the challenges, there are multiple affordances in developing and implementing this type of curriculum for both learners and educators. Also, students exhibited three components of critical consciousness while engaged with the social justice-imbued lesson plans. However, as Freire saw the ability to read the world as a preliminary step for reading the word (or at least simultaneously occurring), my analysis implied that students’ accurate comprehension of the [biological] word developed together with critical contemplation concerning the roots and repercussions of social justice issues within the realms of science and healthcare (i.e., reading the world).

description: In the focus of our paper is a system of axioms that serves as a basis for introducing structural data for $(2n,k)$-manifolds $M^{2n}$, where $M^{2n}$ is a smooth, compact $2n$-dimensional manifold with a smooth effective action of the $k$-dimensional torus $T^k$. In terms of these data a construction of the model space $\mathfrak{E}$ with an action of the torus $T^k$ is given, such that there exists a $T^k$-equivariant homeomorphism $\mathfrak{E}\to M^{2n}$. This homeomorphism induces a homeomorphism $\mathfrak{E}/T^k\to M^{2n}/T^k$. The number $d=n-k$ is called the complexity of an $(2n,k)$-manifold. Our theory comprises toric geometry and toric topology, where $d=0$. It is shown that the class of homogeneous spaces $G/H$ of compact Lie groups, where rk$G=$rk$H$, contains $(2n,k)$-manifolds that have non zero complexity. The results are demonstrated on the complex Grassmann manifolds $G_{k+1,q}$ with an effective action of the torus $T^k$.

description: As technology scales down, the static power is expected to become a significant fraction of the total power. The exponential dependence of static power with the operating temperature makes the thermal profile estimation of high-performance ICs a key issue to compute the total power dissipated in next-generations. In this paper we present accurate and compact analytical models to estimate the static power dissipation and the temperature of operation of CMOS gates. The models are the fundamentals of a performance estimation tool in which numerical procedures are avoided for any computation to set a faster estimation and optimization. The models developed are compared to measurements and SPICE simulations for a 0.12mm technology showing excellent results.

description: The Pebbles research project is investigating how the functionality and the user interface can be spread across all of the computing and input / output devices that one or more users have available. In this way, the hand-held devices can be used to augment the other computers rather than just being a replacement when other computers are not available. As part of this research, we are looking at how multiple people can use their hand-helds to share control of a main computer running either legacy applications, or custom multi-person applications. We are also looking at how information and control can be fluidly moved between the main screen and the individual hand-held screens.

description: We prove that the factorization homologies of a scheme with coefficients in truncated polynomial algebras compute the cohomologies of its generalized configuration spaces. Using Koszul duality between commutative algebras and Lie algebras, we obtain new expressions for the cohomologies of the latter. As a consequence, we obtain a uniform and conceptual approach for treating homological stability, homological densities, and arithmetic densities of generalized configuration spaces. Our results categorify, generalize, and in fact provide a conceptual understanding of the coincidences appearing in the work of Farb--Wolfson--Wood. Our computation of the stable homological densities also yields rational homotopy types which answer a question posed by Vakil--Wood. Our approach hinges on the study of homological stability of cohomological Chevalley complexes, which is of independent interest.

description: Each site of $\mathbb{Z}$ hosts a queue with arrival rate $λ$. A single server, starting at the origin, serves its current queue at rate $μ$ until that queue is empty, and then moves to the longest neighbouring queue. In the critical case $λ= μ$, we show that the server returns to every site infinitely often. We also give a sharp iterated logarithm result for the server's position. Important ingredients in the proofs are that the times between successive queues being emptied exhibit doubly exponential growth, and that the probability that the server changes its direction is asymptotically equal to $1/4$.

description: We study the problem of recovering a block-sparse signal from under-sampled observations. The non-zero values of such signals appear in few blocks, and their recovery is often accomplished using a $\ell_{1,2}$ optimization problem. In applications such as DNA micro-arrays, some prior information about the block support, i.e., blocks containing non-zero elements, is available. A typical way to consider the extra information in recovery procedures is to solve a weighted $\ell_{1,2}$ problem. In this paper, we consider a block sparse model, where the block support has intersection with some given subsets of blocks with known probabilities. Our goal in this work is to minimize the number of required linear Gaussian measurements for perfect recovery of the signal by tuning the weights of a weighted $\ell_{1,2}$ problem. For this goal, we apply tools from conic integral geometry and derive closed-form expressions for the optimal weights. We show through precise analysis and simulations that the weighted $\ell_{1,2}$ problem with optimal weights significantly outperforms the regular $\ell_{1,2}$ problem. We further examine the sensitivity of the optimal weights to the mismatch of block probabilities, and conclude stability under small probability deviations.

Here, we drive magnetization precession by coherent phonons in a metal ferromagnetic nanograting and generate ac-magnetic induction with extremely high amplitude (up to $10$ mT) and nanometer scale localization in the grating grooves. We trigger the magnetization by a laser pulse which excites localized surface acoustic waves. The developed technique has prospective uses in several areas of research and technology, including spatially resolved access to spin states for quantum technologies.

description: The theoretical description of the physics of multi-jets in hadronic collisions at high energies is based on 'merging' methods, which combine short-timescale production of jets with long-timescale evolution of partonic showers. We point out potential implications of the evolution of transverse momentum dependent (TMD) distributions on the structure of multi-jet states at high energies, and in particular on the theoretical systematics associated with multi-jet merging. To analyze this, we propose a new merging methodology, and illustrate its impact by comparing our theoretical results with experimental measurements for $Z$-boson + jets production at the Large Hadron Collider (LHC).

description: This paper generalizes Huang's cohomology theory of grading-restricted vertex algebras to meromorphic open-string vertex algebras (MOSVAs hereafter), which are noncommutative generalizations of grading-restricted vertex algebras introduced by Huang. The vertex operators for these algebras satisfy associativity but do not necessarily satisfy the commutativity. Moreover, the MOSVA and its bimodules considered in this paper do not necessarily have finite-dimensional homogeneous subspaces, though we do require that they have lower-bounded gradings. The construction and results in this paper will be used in a joint paper by Huang and the author to give a cohomological criterion of the reductivity for modules for grading-restricted vertex algebras

Changing Behavior and Promoting Clinical Empathy through a Patient Experience Curriculum
Creators: name: Nelson, Sara W.
Publisher: name: University of Illinois at Chicago
Year: 2024

description: Purpose
This study endeavored to explore how a curriculum that uses a patient experience simulation followed by reflection can lead to clinical empathy in learners and whether this experience leads to behavioral change. Further, the study aimed to contribute insight regarding how clinical empathy may best be taught to health professions students.

Methods
Senior medical students participated in an in-situ patient experience simulation in an academic emergency department. The simulation was followed by a written reflection and then a structured debrief with faculty conducted at the end of the students’ clerkship. A thematic analysis was performed on transcripts of the group debriefs.

Results
Learners described several behavioral changes they made after this intervention. First, learners discussed performing more small acts of kindness to improve patient care and humanize the patient experience. Second, learners discussed seeking to improve their communication through acknowledgement and validation of the patient experience. And third, learners described actions to keep patients informed through frequent check-ins and setting expectations on time. As such, learners’ behavioral changes align with the conceptualization of “clinical empathy” in which emotional attunement to the patient experience allows the clinician to validate patient feelings and act accordingly to enhance care.

Conclusions
This study explores the effects of a curricular tool to cultivate empathy in health profession students. This curriculum created an emotional and physical experience for learners, thereby creating a deeper understanding of clinical empathy than might occur in standard skills-based approach. These findings suggest that empathy is not simply transactional for health professions students, and that an understanding of the patient experience leads to actions that improve the patient experience and alleviate suffering.

description: Low power oriented circuit optimization consists in selecting the best alternative between gate sizing, buffer insertion and logic structure transformation, for satisfying a delay constraint at minimum area cost. In this paper we used a closed form model of delay in CMOS structures to define metrics for a deterministic selection of the optimization alternative. The target is delay constraint satisfaction with minimum area cost. We validate the design space exploration method, defining maximum and minimum delay bounds on logical paths. Then we adapt this method to a "constant sensitivity method" allowing to size a circuit at minimum area under a delay constraint. An optimisation protocol is finally defined to manage the trade-off performance constraint - circuit structure. These methods are implemented in an optimization tool (POPS) and validated by comparing on a 0.25$μ$m process, the optimization efficiency obtained on various benchmarks (ISCAS?85) to that resulting from an industrial tool.

description: Question answering (QA) is a highly complex task that brings together classification, clustering, retrieval, and extraction. Question answering systems include various statistical and rule-based components that combine and form multiple strategies for finding answers. However, in real-life scenarios efficiency constraints make it infeasible to simultaneously use all available strategies in a QA system. To address this issue, we present an approach for carefully selecting answering strategies that are likely to benefit individual questions, without significantly reducing performance. We evaluate the impact of strategy selection on question answering performance at several important QA stages: document retrieval, answer extraction, and answer merging. We present strategy selection experiments using a statistical question answering system, and we show significant efficiency improvements. By selecting 10% of the available answering strategies, we obtained similar performance when compared to using all of the strategies combined.

description: We have searched for millimetre-wave line emission from ethylene oxide (c-C_2H_4O) and its structural isomer acetaldehyde (CH_3CHO) in 11 molecular clouds using SEST. Ethylene oxide and acetaldehyde were detected through multiple lines in the hot cores NGC 6334F, G327.3-0.6, G31.41+0.31, and G34.3+0.2. Acetaldehyde was also detected towards G10.47+0.03, G322.2+0.6, and Orion 3'N, and one ethylene oxide line was tentatively detected in G10.47+0.03. Column densities and rotational excitation temperatures were derived using a procedure which fits the observed line intensities by finding the minimum chi (2) -value. The resulting rotational excitation temperatures of ethylene oxide and acetaldehyde are in the range 16 - 38 K, indicating that these species are excited in the outer, cooler parts of the hot cores or that the excitation is significantly subthermal. For an assumed source size of 20'', the deduced column densities are (0.6 - 1)*E(14) cm(-2) for ethylene oxide and (2 - 5)*E(14) cm(-2) for acetaldehyde. The fractional abundances with respect to H_2 are X{[c-C_2H_4O]}=(2 - 6)*E(-10) , and X{[CH_3CHO]}=(0.8 - 3)*E(-9) . The ratio X{[CH_3CHO]}/X{[c-C_2H_4O]} varies between 2.6 (NGC 6334F) and 8.5 (G327.3-0.6). We also detected and analysed multiple transitions of CH_3OH, CH_3OCH_3, C_2H_5OH, and HCOOH. The chemical, and possibly evolutionary, states of NGC 6334F, G327.3-0.6, G31.41+0.31, and G34.3+0.2 seem to be very similar.

description: A number of seemingly unrelated problems involving the proximity of N points in the plane are studied, such as finding a Euclidean minimum spanning tree, the smallest circle enclosing the set, k nearest and farthest neighbors, the two closest points, and a proper straight-line triangulation. For most of the problems considered a lower bound of O(N log N) is shown. For all of them the best currently-known upper bound is O(N2 ) or worse. The purpose of this paper is to introduce a single geometric structure, called the Voronoi diagram, which can be constructed rapidly and contains all of the relevant proximity information in only linear space. The Voronoi diagram is used to obtain D(N log N) algorithms for all of the problems.

description: This paper describes two research projects that develop new low-cost techniques for testing devices with multiple high-speed (2 to 5 Gbps) signals. Each project uses commercially available components to keep costs low, yet achieves performance characteristics comparable to (and in some ways exceeding) more expensive ATE. A common CMOS FPGA-based logic core provides flexibility, adaptability, and communication with controlling computers while customized positive emitter-coupled logic (PECL) achieves multi-gigahertz data rates with about $\pm$25ps timing accuracy.

Exploring the Reactivity of Copper Towards the Synthesis of Reactive Carbonyl Electrophiles

Publisher: name: University of Illinois at Chicago

description: Carbonylation represents an atom economical approach in which inexpensive CO is used as a C1 feedstock. In recent years, transition metal-catalyzed carbonylative couplings have been studied extensively. Among various transition metals, copper has emerged as a sustainable alternative due to its relative abundance and inexpensive and non-toxic nature. The unique reactivity of copper has been used to develop various carbonylative C-C and C-X bond-forming reactions with alkyl halides previously. Although strong nucleophiles were required to reduce the alkyl electrophiles under copper catalysis conditions, the scope of weak nucleophiles remains unexplored.
The first part of the thesis focuses on the synthesis of potassium acyltrifluoroborates (KATs), for which a copper-catalyzed carbonylative borylation method of synthesis was recently reported. KATs are an important class of compounds with immense applications in bioconjugation, polymer, and materials chemistry. This study represents a more straightforward synthesis of KATs than the previous method by mediating coupling between mixed anhydrides of abundant carboxylic acids and commercially-available B2(pin)2 in the presence of a commercial copper catalyst and subsequent quenching by aqueous KHF2. This method provides a broad scope, including important amino acid-derived KATs.
The later parts focus on the scope of weak nucleophiles such as carbonates and fluorides in carbonylation reactions. We hypothesized that the weak nucleophiles would have lower reduction potential to activate the alkyl halides, and hence would require photoactivation. When carbonate base was employed under photocatalytic conditions, carboxylic acid anhydrides were obtained, whereas acyl fluorides were synthesized with fluoride base. Mechanistic studies indicated a general mechanism for both the transformations involving heterogeneous copper(0)-mediated radical carbonylation pathway. Further extension of this method resulted in a new reactivity, delivering very important tetralone derivatives when the amine base was used, allowing internal aromatic groups to act as Freidel-Crafts nucleophiles.

description: The dynamics of flooding are primarily influenced by the shape, height, and roughness (friction) of the underlying topography. For this reason, mechanisms to mitigate floods frequently employ structural measures that either modify topographic elevation, e.g., through the placement of levees and sandbags, or increase roughness, e.g., through revegetation projects. However, the configuration of these measures is typically decided in an ad hoc manner, limiting their overall effectiveness. The advent of high-performance surface water modeling software and improvements in black-box optimization suggest that a more principled design methodology may be possible. This paper proposes a new computational approach to the problem of designing structural mitigation strategies under physical and budgetary constraints. It presents the development of a problem discretization amenable to simulation-based, derivative-free optimization. However, meta-heuristics alone are found to be insufficient for obtaining quality solutions in a reasonable amount of time. As a result, this paper proposes novel numerical and physics-based procedures to improve convergence to a high-quality mitigation. The efficiency of the approach is demonstrated on hypothetical dam break scenarios of varying complexity under various mitigation budget constraints. In particular, experimental results show that, on average, the final proposed algorithm results in a 65% improvement in solution quality compared to a direct implementation.

description: We study the double-winding Wilson loops in the SU(N) Yang-Mills theory on the lattice. We discuss how the area law falloff of the double-winding Wilson loop average is modified by changing the enclosing contours C1 and C2 for various values of the number of color N. By using the strong coupling expansion, we evaluate the double-winding Wilson loop average in the lattice SU(N) Yang-Mills theory. Moreover, we compute the double-winding Wilson loop average by lattice Monte Carlo simulations for SU(2) and SU(3). We further discuss the results from the viewpoint of the Non-Abelian Stokes theorem in the higher representations.

description: Corpus driven machine translation approaches such as Phrase-Based Statistical Machine Translation and Example-Based Machine Translation have been successful by using word alignment to find translation fragments for matched source parts in a bilingual training corpus. However, they still cannot properly deal with systematic translation for insertion or deletion words between two distant languages. In this work, we used syntactic chunks as translation units to alleviate this problem, improve alignments and show improvement in BLEU for Korean to English and Chinese to English translation tasks.

description: The chapter focuses on the use of student feedback on teaching during practical phases in teacher education. After a brief introduction into the general relevance and validity of students’ perceptions on teaching, and on the use of student feedback for teaching development, core findings from two comparable quasi-experimental studies from Germany and Switzerland are presented in detail. The studies focus on the change of attitudes towards student feedback and towards reflection on teaching. The chapter concludes with a discussion of challenges and opportunities for the use of student feedback as an instrument for reflection on teaching and professional development for pre-service teachers.

Do Android Taint Analysis Tools Keep Their Promises?

description: In recent years, researchers have developed a number of tools to conduct taint analysis of Android applications. While all the respective papers aim at providing a thorough empirical evaluation, comparability is hindered by varying or unclear evaluation targets. Sometimes, the apps used for evaluation are not precisely described. In other cases, authors use an established benchmark but cover it only partially. In yet other cases, the evaluations differ in terms of the data leaks searched for, or lack a ground truth to compare against. All those limitations make it impossible to truly compare the tools based on those published evaluations. We thus present ReproDroid, a framework allowing the accurate comparison of Android taint analysis tools. ReproDroid supports researchers in inferring the ground truth for data leaks in apps, in automatically applying tools to benchmarks, and in evaluating the obtained results. We use ReproDroid to comparatively evaluate on equal grounds the six prominent taint analysis tools Amandroid, DIALDroid, DidFail, DroidSafe, FlowDroid and IccTA. The results are largely positive although four tools violate some promises concerning features and accuracy. Finally, we contribute to the area of unbiased benchmarking with a new and improved version of the open test suite DroidBench.
Choosing Sampling Rates for Robot Control

description: In our previous research, we experimentally implemented and evaluated the effect of dynamics compensation in model-based control algorithms. In this paper, we evaluate the effect of changing the control sampling period on the performance of the computed-torque and independent joint control schemes. While the former utilizes the complete dynamics model of the manipulator, the latter assumes a decoupled and linear model of the manipulator dynamics. We discuss the design of controller gains for both the computed-torque and the independent joint control schemes and establish a framework for comparing their trajectory tracking performance. Our experiments show that within each scheme the trajectory tracking accuracy varies slightly with the change of the sampling rate. However, at low sampling rates the computed- torque scheme outperforms the independent joint control scheme. Based on our experimental results, we also conclusively establish the importance of high sampling rates as they result in an increased stiffness of the system.
