description: Recent improvements in the sensitivity and precision of the radial velocity (RV) method for exoplanets have brought it close, but not quite to, the threshold ($\sim$10 cm/s) required to detect Earth-mass and other potentially habitable planets around Sun-like stars. Stellar activity-driven noise in RV measurements remains a significant hurdle to achieving this goal. While various efforts have been made to disentangle this noise from real planetary signals, a greater understanding of the relationship between spectra and stellar activity is crucial to informing stellar activity mitigation. We use a partially automated method to analyze spectral lines in a set of observations of the young, active star $ε$ Eridani from the high-precision spectrograph NEID, correlate their features (depth, full width at half maximum, and integrated flux) with known activity indicators, and filter and curate for well-behaved lines whose shape changes are sensitive to certain types of stellar activity. We then present a list of 9 lines correlated with the S-index in all three line features, including 4 newly-identified activity-sensitive lines; as well as additional lines correlated with S-index in at least one feature, and discuss the possible implications of the behavior observed in these lines. Our line lists represent a step forward in the empirical understanding of the complex relationships between stellar activity and spectra, and illustrate the importance of studying the time evolution of line morphologies with stabilized spectrographs, in the overall effort to mitigate activity in the search for small, potentially Earth-like exoplanets.

Non-Commutative Worlds

Year: 2004
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: This paper shows how the forms of gauge theory, Hamiltonian mechanics and quantum mechanics arise from a non-commutative framework for calculus and differential geometry. Discrete calculus is seen to fit into this pattern by reformulating it in terms of commutators. Differential geometry begins here, not with the concept of parallel translation, but with the concept of a physical trajectory and the algebra related to the Jacobi identity that governs that trajectory. The paper discusses how Poisson brackets give rise to Jacobi identity, and how Jacobi identity arises in combinatorial contexts, including graph coloring and knot theory. The paper gives a highly sharpened derivation of results of Tanimura on the consequences of commutators that generalize the Feynman-Dyson derivation of electromagnetism, and a generalization of the original Feynman-Dyson result that makes no assumptions about commutators. The latter result is a consequence of the definitions of the derivations in a particular non-commutative world. Our generalized version of electromagnetism sheds light on the orginal Feynman-Dyson derivation, and has many discrete models.

description: 5-[4-(dimethylamino)benzylidene) pyrimidine 2,4,6(1H,3H,5H)]-trione (DMP-3H), the receptor was synthesized which played a chemosensor role for cyanide ion (CN−) in aqueous solution with colorimetric and fluorescence turn-off responses. Upon addition of CN− ion into the solution containing the receptor, a color change visible to the naked eye was observed from yellow to colourless and also, the fluorescence of the solution was immediately quenched. Moreover, DMP-3H exhibited a selective response to cyanide ion over many other anions such as F−, Cl−, Br−, I−, SO2−3 , OCN−, ClO−3 , CO2−3 , IO−3 , N−3 , C2O2−4 and SCN−. The detection limit toward CN− was 8.1 × 10−7 mol.L−1, which is satisfactory enough for monitoring CN− levels in physiological and environmental systems.

description: Deep Neural Networks (DNNs) demonstrate remarkable capabilities in learning complex hierarchical data representations, but the nature of these representations remains largely unknown. Existing global explainability methods, such as Network Dissection, face limitations such as reliance on segmentation masks, lack of statistical significance testing, and high computational demands. We propose Inverse Recognition (INVERT), a scalable approach for connecting learned representations with human-understandable concepts by leveraging their capacity to discriminate between these concepts. In contrast to prior work, INVERT is capable of handling diverse types of neurons, exhibits less computational complexity, and does not rely on the availability of segmentation masks. Moreover, INVERT provides an interpretable metric assessing the alignment between the representation and its corresponding explanation and delivering a measure of statistical significance. We demonstrate the applicability of INVERT in various scenarios, including the identification of representations affected by spurious correlations, and the interpretation of the hierarchical structure of decision-making within the models.

Expectations of motherhood: Citizenship and political mobilization for midwifery in Virginia
Creators: name: Craven, Christa C.
Publisher: name: American University
Year: 2023

description: What prompts women to become politically mobilized around healthcare issues? And how do their resultant expectations and strategies influence the outcome of their mobilization? In this study, I explore women's support of midwifery and homebirth in the context of political and economic changes around healthcare and shifting cultural meanings of motherhood and citizenship in the United States. The recent grassroots organization among homebirthers in Virginia to enhance local midwifery services is the subject of this inquiry. First, I demonstrate historically how women's political mobilization around past healthcare initiatives---such as the movement to improve infant and maternal health in the early 1900s and the Natural Childbirth Movement during the mid- to late 1900s---has further stratified, rather than ameliorated, women's uneven access to healthcare services. Most often, these movements have enhanced reproductive options for white, middle-class and affluent women, but have continued to restrict the reproductive choices of women of color and poor women. In this context, the contemporary political organizing for homebirth midwifery in Virginia---primarily among white, educated women who represent a variety of political, religious, and class backgrounds---further illustrates the diverse expectations and experiences of motherhood, citizenship, and political action among different constituencies of women. In response to medical and state characterizations of homebirthers as pathological mothers, many midwifery supporters have denied participation in political activity---although they continued to perform actions that they defined as political. This seemingly paradoxical strategy is one way that some homebirthers understood themselves as political actors, but only in their capacity as "respectable," apolitical mothers. Additionally, some midwifery advocates have begun to define themselves as "consumers" of healthcare services---particularly in conversation with government officials---reflecting a neoliberal definition of citizenship under which the state prioritizes "consumer rights" over the social, economic, and political rights of its citizens. In this dissertation, I explore the consequences of these strategies for midwifery supporters. I highlight the contradictions between most midwifery supporters' aspiration to support low-cost, community-based reproductive care for all women and the increasing commercialization and stratification of alternative healthcare in the U.S., including midwifery services.

description: We predict that a family of antiperovskite materials realize a higher order topological insulator phase, characterized by a previously introduced $\mathbb{Z}_4$ index. A tight binding model and a $k\cdot p$ model are used to capture the physics of the bulk, surface and hinge states of these materials. A phase diagram of the higher order and weak topological invariants is obtained for the tight binding model. The mirror Chern number is also discussed. In order to reveal the gapless hinge states in the presence of mirror Chern surface states, several ways of opening the surface gap are proposed and confirmed by calculation, including cleaving the crystal to reveal a low-symmetry surface, building a heterostructure, and applying strain. Upon opening the surface gap, we are able to study the hinge states by computing the momentum space band structure and real space distribution of mid-gap states.

Understanding variations in murder clearance rates: The influence of the political environment
Creators: name: Davies, Heather Janina
Publisher: name: American University
Year: 2023

description: A crucial challenge facing police administrators, especially in times of heightened political and public attention, is the pressure to make appropriate organizational and procedural changes to improve homicide investigation performance, measured by an increase in murder clearance rates. Murder clearance rates are politically salient, inviting the charge that the police manipulate the numbers so that the mayor looks good at the next election. The purpose of this study is to analyze the impact of the political environment on murder clearance rates. The research strategy employed a multi-method research design, using both quantitative and qualitative approaches. The quantitative research design is based on data organized using a pooled cross-section time-series analysis of 59 of the largest cities in the United States over the period 1970 to 1999. The model estimates the impact of the mayoral election year, murder offense rate, police expenditures, number of employees, population, and state unemployment rate on murder clearance rates. The model was analyzed using cross-sectional time-series feasible generalized least squares regression. The estimate for the critical mayoral election variable was re-estimated to test for simultaneity, omitted variables, and different functional forms. The results consistently reveal no discernible political impact of the mayoral election year on murder clearance rates. The results also imply that the addition of sworn officers improves the murder clearance rate, but simply adding more resources (e.g., patrol cars, equipment, training, personnel, etc.) does not. The qualitative design was conducted in one large city. It examined department documents, along with extensive field observations and interviews. The case study demonstrated that the media, mayor, city council and prosecuting attorney exercised a significant impact on police practices and procedures, investigative decision-making and even fluctuations in homicide case closures. Continued review of the political environment's influence on police practices and procedures will provide more evidence as to its actual impact. This dissertation identifies the need to develop, implement and evaluate an investigative performance model that includes more functional performance measures for all homicide investigation activities and improved accountability for the use of resources.
Enhanced Water Nucleation and Growth Based on Microdroplet Mobility on Lubricant-Infused Surfaces

description: Lubricant-infused surfaces (LISs) can promote stable dropwise condensation and improve heat transfer rates due to a low nucleation free-energy barrier and high droplet mobility. Topographical differences in the oil surface cause water microdroplets to rigorously self-propel long distances, continuously redistributing the oil film and potentially refreshing the surface for re-nucleation. Using high-speed microscopy, we reveal that during water condensation on LISs, the smallest visible droplets (diameter ~ 1um, qualitatively representing nucleation) predominantly emerge in oil-poor regions due to a smaller thermal activation barrier. Considering the significant heat transfer performance of microdroplets (< 10um) and transient characteristic of microdroplet movement, we compare the apparent nucleation rate density and water collection rate for LISs with oils of different viscosity and a solid hydrophobic surface at a wide range of subcooling temperatures. Generally, the lowest lubricant viscosity leads to the highest nucleation rate density. We characterize the length and frequency of microdroplet movement and attribute the nucleation enhancement primarily to higher droplet mobility and surface refreshing frequency. Interestingly and unexpectedly, hydrophobic surfaces outperform high-viscosity LISs at high subcooling temperatures, but are generally inferior to any of the tested LISs at low temperature differences. To explain the observed non-linearity between LISs and the solid hydrophobic surface, we introduce two dominant regimes that influence the condensation efficiency: mobility-limited and coalescence-limited. Our findings advance the understanding of dynamic water-lubricant interactions and provide new design rationales for choosing surfaces for enhanced dropwise condensation and water collection efficiencies.

description: The topological properties of non-Hermitian Hamiltonian is a hot topic, and the theoretical studies along this research line are usually based on the two-level non-Hermitian Hamiltonian (or, equivalently, a spin-$1/2$ non-Hermitian Hamiltonian). We are motivated to study the geometrical phases of a three-level Lieb lattice model (or, equivalently, a spin-$1$ non-Hermitian Hamiltonian) with the complex hopping and flat band in the context of a polariton condensate, with the emphasis on the higher spin degree of freedom on topological properties of non-Hermitian Hamiltonian. The topological invariants are calculated by both winding numbers in the Brillouin zone and the geometrical phase of Majorana stars in the Bloch sphere. Besides, we provide an intuitive way to study the topological phase transformation in high dimensions, and the flat band offers a platform to define the high spin topological phase transition on the Bloch sphere. According to the trajectories of the Majorana stars, we calculate the geometrical phases of the Majorana stars, and we find they have a jump when the parameters change from the trivial phase to the topological phase. Besides, the correlation phase of Majorana stars will rise along with the increase of the imaginary parts of the hopping energy.

description: The District of Columbia Public School System uses the results of the Stanford Nine mathematics test to determine if students have acquired functional and advanced skills in mathematics. The impact of the student's performance on this test is significant, for the testing outcome may impact a student's eligibility to graduate from high school and the careers of educators involved with this process can be negatively affected. In fact, poor test scores have already resulted in teacher transfers, principal firings, and total school transformations. The Stanford Nine mathematics test scores for high school students are very low. A student's performance falls in one of three categories: Below Basic, Basic, Proficient, and Advanced. For the last three years, nearly 80% of the students tested fell in the Below Basic category. Hence, the motivation for this research was to document how schools are preparing students for the test and record what kind of impact that test preparation efforts are having on teachers and students. Intensive interviewing revealed that students and teachers feel that they are unfairly pressured to reach testing goals although they are not provided the necessary time or resources to succeed. Many of the students admitted that they do not take the test seriously because their performance on the test does not positively or negatively impact their immediate academic standing in school. The research outcomes did not support the assumption that test score differences were due to varying teaching methods. The teachers interviewed from the four high schools offered similar strategies for attacking typical Stanford Nine mathematics problems, and some of the schools used the same strategy to engage the entire student population in test readiness activities. The results of a sample test administered to high school students from the four schools showed a strong relationship between test scores and socio-economic factors; the schools whose students were products of poor neighborhoods generally posted lower test scores. Also, hypothesis testing results indicated that there was not a significant relationship between grades and sample test scores. It is apparent that a plan to improve Stanford Nine mathematics scores for high school students will require a comprehensive effort that involves social as well as educational reforms. Higher test scores will become a reality if students are held accountable for their performance, if parents are motivated to support the educational process more aggressively, and if educators continue to embrace effective test preparation strategies.

The hybrid EoS is constructed using the recently proposed Effective-Field-Theory motivated Relativistic Mean-Field model (E-RMF) for the hadron phase with different parameter sets and MIT Bag model for the quark phase with different Bag constants to construct hybrid EoS. The mixed-phase formed by the hadron-quark phase transition is studied using the Gibbs construction. The nuclear matter properties for hybrid EoS are calculated and their variation with the bag constant is determined.

description: The impact of living in an ethnic enclave on earnings growth of immigrants in Canada is examined using the 1981–2001 Censuses. Consistent with U.S. findings, enclaves are found to have a negative impact on the earnings growth of male immigrants. A negative impact is also found for female immigrants. Living in an enclave was found to be particularly harmful for individuals immigrating as adults, especially for females, but did not affect immigrants who arrived at a young age. Enclaves had a more negative impact on high-skilled male immigrants, especially if they had received the bulk of their education outside of Canada. Enclaves also hindered language skills.

Spectra of the sources cold be well described by a power law with photoabsorption. It is shown that the value of absorption column in the case of RXTE observation of IGR J16318-4848 performed on March 14.1, 2003 is somewhat higher that that obtained by XMM observatory on Feb 10.7 2003. This could imply that the source has variable absorption, presumably connected with an orbital phase of the binary system. It is noted, that all three X-ray sources, discovered by INTEGRAL observatory in the sky region of (l,b)~(336,0) (IGR J16318-4848, IGR J16320-4751 and IGR J16358-4726) have large intrinsic photoabsorption and could be high mass X-ray binaries. This hypothesis has indirect support from the fact that their are located close to the Norma spiral arm tangent, i.e. in the region of enhanced concentrations of young massive stars. If they are reside within this spiral arm some rough estimation of the sources distance could be made -- D~6-8 kpc.

description: Extreme scattering events (ESEs) are observed as dramatic ($>50\%$) drops in flux density that occur over an extended period of weeks to months. Discrete plasma lensing structures are theorized to scatter the radio waves produced by distant sources such as pulsars, causing the signature decrease in flux density and characteristic caustic spikes in ESE light curves. While plasma lens models in the extant literature have reproduced key features of ESE light curves, they have all faced the problem of being highly over-dense and over-pressured relative to the surrounding interstellar medium (ISM) by orders of magnitude. We model ESEs by numerically ray-tracing through analytic, volumetric plasma lens models by solving the eikonal equation. Delaunay triangulation connecting the rays approximates the wavefront, generating a mapping from the observer plane to the source plane to account for multiple-imaging. This eikonal method of ray-tracing is tested against known analytic solutions and is then applied to a three-dimensional Gaussian-distributed electron volume density lens, and a filament model inspired by Grafton et al. (2023). We find convergence of our numerical results with established analytic solutions validating our numerical method, and reproduce ESE-like light curves. Our numerical ray-tracing method lends itself well to exploring the lensing effects of volumetric turbulence as well as sheet-like lenses, which is currently in progress.

Sunset reviews at the ITC and foreign participation

description: The Uruguay Round Agreement Act passed in 1994 required the review of antidumping duty orders every five years to determine whether an antidumping duty order should remain in effect. The United States International Trade Commission (ITC) has been criticized for its voting behavior in these reviews. It was opined that when foreign firms do not participate, those are the orders that should be revoked and when foreign firms do participate, those are the orders to be maintained. It was argued that foreign firms would only participate if they wanted to aggressively re-enter the U.S. market. This study focuses on ITC voting in these reviews and the foreign decision to participate. Two studies to date have looked at the ITC voting behavior in these proceedings. Whereas these previous works only studied review of the antidumping orders in place prior to January 1, 1995, referred to as "transitional reviews", this study included reviews through June 2002. Another difference is that this study relies on data from the ITC public reports whereas the previous studies used more aggregate data. This study attempts to analyze whether foreign firm participation and overt congressional pressure impacts decision-making at the ITC. The probit modeling results indicated that overt congressional pressure was not significant in ITC decision-making. The modeling results suggest that foreign participation may reduce the likelihood of the ITC to decide to maintain the dumping order. In criticizing the ITC on its voting behavior the assumption was made that firms only participate if they have the intention of aggressively re-entering the U.S. market. Is this the only consideration in the firm decision or are there other explanations such as firms attempting to free-ride? Again probit analysis was used to look at the characteristics that tend to increase foreign firm participation. This modeling provided mixed indications on the issue of potential free-riding. To get further at the intent of foreign firms, subject trade flows prior to the removal of the dumping duty were compared to trade flows of the same products after the revocation of the order. This analysis did not support the proposition that foreign firms only participate to aggressively re-enter the U.S. market.

description: The problem of generalizing deep neural networks from multiple source domains to a target one is studied under two settings: When unlabeled target data is available, it is a multi-source unsupervised domain adaptation (UDA) problem, otherwise a domain generalization (DG) problem. We propose a unified framework termed domain adaptive ensemble learning (DAEL) to address both problems. A DAEL model is composed of a CNN feature extractor shared across domains and multiple classifier heads each trained to specialize in a particular source domain. Each such classifier is an expert to its own domain and a non-expert to others. DAEL aims to learn these experts collaboratively so that when forming an ensemble, they can leverage complementary information from each other to be more effective for an unseen target domain. To this end, each source domain is used in turn as a pseudo-target-domain with its own expert providing supervisory signal to the ensemble of non-experts learned from the other sources. For unlabeled target data under the UDA setting where real expert does not exist, DAEL uses pseudo-label to supervise the ensemble learning. Extensive experiments on three multi-source UDA datasets and two DG datasets show that DAEL improves the state of the art on both problems, often by significant margins. The code is released at \url{https://github.com/KaiyangZhou/Dassl.pytorch}.

description: We present a general unified approach for the study of quantum thermal machines, including both heat engines and refrigerators, operating under periodic adiabatic driving and in contact with thermal reservoirs kept at different temperatures. We show that many observables characterizing this operating mode and the performance of the machine are of geometric nature. Heat-work conversion mechanisms and dissipation of energy can be described, respectively, by the antisymmetric and symmetric components of a thermal geometric tensor defined in the space of time-dependent parameters generalized to include the temperature bias. The antisymmetric component can be identified as a Berry curvature, while the symmetric component defines the metric of the manifold. We show that the operation of adiabatic thermal machines, and consequently also their efficiency, are intimately related to these geometric aspects. We illustrate these ideas by discussing two specific cases: a slowly driven qubit asymmetrically coupled to two bosonic reservoirs kept at different temperatures, and a quantum dot driven by a rotating magnetic field and strongly coupled to electron reservoirs with different polarizations. Both examples are already amenable for an experimental verification.
