description: We contribute to the discussion on parsing performance in NLP by introducing a measurement that evaluates the differences between the distributions of edge displacement (the directed distance of edges) seen in training and test data. We hypothesize that this measurement will be related to differences observed in parsing performance across treebanks. We motivate this by building upon previous work and then attempt to falsify this hypothesis by using a number of statistical methods. We establish that there is a statistical correlation between this measurement and parsing performance even when controlling for potential covariants. We then use this to establish a sampling technique that gives us an adversarial and complementary split. This gives an idea of the lower and upper bounds of parsing systems for a given treebank in lieu of freshly sampled data. In a broader sense, the methodology presented here can act as a reference for future correlation-based exploratory work in NLP.

Exploring the potential X-ray counterpart of the puzzling TeV gamma-ray source HESS J1507-622 with new Suzaku observations

description: The unidentified VHE (E>100 GeV) gamma-ray source HESS J1507-622 seems to not fit into standard models for sources related to young supernova remnants, pulsar wind nebulae, or young stellar populations in general. This is due to its intrinsically extended, but yet compact morphology, coupled with a relative large offset (~3.5 deg) from the Galactic plane. Therefore, it has been suggested that this object may be the first representative of a new distinct class of extended off-plane gamma-ray sources. The distance to HESS J1507-622 is the key parameter to constrain the source's most important properties, such as age and energetics of the relativistic particle population. In this article we report on results of follow-up observations of the potential X-ray counterpart with Suzaku. We present detailed measurements of its spectral parameters and find a high absorbing hydrogen column density, compatible with the total amount of Galactic gas in this direction. In comparisons to measurements and models of the Galactic three-dimensional gas distribution we show that the potential X-ray counterpart of HESS J1507-622 may be located at the far end of the Galaxy. If the gamma-ray source is indeed physically connected to this extended X-ray source, this in turn would place the object outside of the usual distribution of Galactic VHE gamma-ray emitters.

Short gamma-ray bursts in the "time-reversal" scenario

description: Short gamma-ray bursts (SGRBs) are among the most luminous explosions in the Universe and their origin still remains uncertain. Observational evidence favors the association with binary neutron star or neutron star-black hole (NS-BH) binary mergers. Leading models relate SGRBs to a relativistic jet launched by the BH-torus system resulting from the merger. However, recent observations have revealed a large fraction of SGRB events accompanied by X-ray afterglows with durations $\sim10^2\!-\!10^5~\mathrm{s}$, suggesting continuous energy injection from a long-lived central engine, which is incompatible with the short ($\lesssim1~\mathrm{s}$) accretion timescale of a BH-torus system. The formation of a supramassive NS, resisting the collapse on much longer spin-down timescales, can explain these afterglow durations, but leaves serious doubts on whether a relativistic jet can be launched at merger. Here we present a novel scenario accommodating both aspects, where the SGRB is produced after the collapse of a supramassive NS. Early differential rotation and subsequent spin-down emission generate an optically thick environment around the NS consisting of a photon-pair nebula and an outer shell of baryon-loaded ejecta. While the jet easily drills through this environment, spin-down radiation diffuses outwards on much longer timescales and accumulates a delay that allows the SGRB to be observed before (part of) the long-lasting X-ray signal. By analyzing diffusion timescales for a wide range of physical parameters, we find delays that can generally reach $\sim10^5~\mathrm{s}$, compatible with observations. The success of this fundamental test makes this "time-reversal" scenario an attractive alternative to current SGRB models.

Keeping PACE with the Pandemic: Experiences from and Impacts of COVID-19 on Care Provision Among North Carolina’s Programs of All-Inclusive Care for the Elderly, a Qualitative Study
Creators: name: Aggarwal, Neha
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: Background: The novel coronavirus disease 2019 (COVID-19) pandemic has deeply affected long-term care (LTC) for older adults, particularly in Programs of All-Inclusive Care for the Elderly (PACE). Older adults are more susceptible to serious illness and/or death from COVID-19, so studying care for this population is important. The pandemic arose in the midst of a larger LTC crisis in the United States centered on an aging population, unsustainability of current financing methods, and provider and staff shortages, among other challenges. COVID-19 is an opportunity to reform LTC, and this study may help shape the future of LTC by examining the resilience of the PACE model against the health system pressures of COVID-19.

Objective: This study investigates the immediate and long-term effects of COVID-19 on care provision in North Carolina’s PACE (NC PACE) programs. Since PACE is organized by state, the research team chose to investigate sites in North Carolina.

Methods: NC PACE administrators were recruited and interviewed through online audio conferencing with a structured interview designed by the research team. The totality of NC PACE (N=12) was represented in the study. The interviews were transcribed, coded, and qualitatively analyzed using thematic analysis. 

Results: Five themes emerged from thematic analysis, each with 2-3 subthemes: insufficient access to and integration with LTC providers and medical and mental healthcare specialists, reevaluation of the core PACE model with the transition to home-based care, that the provision of high-touch care promoted participants’ psychosocial wellbeing, reorientation to pivot toward family-oriented care delivery, and that a culture of caring enabled a successful COVID-19 response. 

Conclusion: PACE was overall successful in mounting a COVID-19 response that upheld safety of its participants, promoted the physical and mental wellbeing of its participants, and responded to the needs of informal/family caregivers. Administrators project that PACE’s service model has permanently changed after the pandemic toward increased home-based care. Results from this study also have implications for the provision of mental health care in the PACE service population and for the federal government’s financial relationship with PACE. PACE’s success during a period in which it was difficult to uphold care quality presents a learning opportunity for LTC in the future.

description: We study the universal scaling behavior of the entanglement entropy of critical theories in $2+1$ dimensions. We specially consider two fermionic scale-invariant models, free massless Dirac fermions and a model of fermions with quadratic band touching, and numerically study the two-cylinder entanglement entropy of the models on the torus. We find that in both cases the entanglement entropy satisfies the area law and has the subleading term which is a scaling function of the aspect ratios of the cylindrical regions. We test the scaling of entanglement in both the free fermion models using three possible scaling functions for the subleading term derived from a) the quasi-one-dimensional conformal field theory, b) the bosonic quantum Lifshitz model, and c) the holographic AdS/CFT correspondence. For the later case we construct an analytic scaling function using holography, appropriate for critical theories with a gravitational dual description. We find that the subleading term in the fermionic models is well described, for a range of aspect ratios, by the scaling form derived from the quantum Lifshitz model as well as that derived using the AdS/CFT correspondence (in this case only for the Dirac model). For the case where the fermionic models are placed on a square torus we find the fit to the different scaling forms is in agreement to surprisingly high precision.

description: This study analyzes 26 presumptive Vibrio alginolyticus strains extracted from two fish farms (Khenis and Hergla, East Tunisia) that raised sea bream (Sparus aurata) and sea bass (Dicentrarchus labrax). In addition, from a shellfish farm located in Menzel Jmil, North Tunisia that raises mussels (Mytilus edulis) and oysters (Crassostrea gigas).
We have evaluated (i) the discriminatory power of PCR-RFLP for identification of closely related strains, (ii) the antibiotic resistance of the V. alginolyticus strains and (iii) their ability to form a biofilm in aquaculture farm.
Results showed that there is great heterogeneity in the diversity observed via the PCR-RFLP method related to the number of 20 genotypes generated by the two enzymes SduI and FaqI tested. The heterogeneity was observed in both fish (aquaculture farm) and bivalve (shellfish farm) origins, as well as in the same sample.
For antibiotic resistance, all isolates present a high resistance to ampicillin, erythromycin, cefotaxime, kanamycin and doxycycline. The resistance is displayed by 15 distinct profiles.
The Multiple Antibiotic resistance (MAR) index was ranged from 0.55 to 0.80 for the isolates from the aquaculture farm of Hergla followed by the index aquaculture farm of Khenis (0.55 to 0.75). While for the shellfish farm of Menzel Jmil the index ranges from 0.50 to 0.65. This finding indicated high-risk sources of antibiotic contamination in the three locations. Isolates from aquaculture systems with strong biofilm formation have been found to be resistant to antibiotics, which may allow them to survive longer in these environments.
Present findings could be relevant in aquaculture systems and underscore the importance of the linkage between adhesion, antibiotic susceptibility, and genetic diversity of these pathogenic bacteria to avoid fish and shellfish diseases. The results will provide helpful guidance on how to use antibiotics to control Vibrio alginolyticus diseases in aquaculture to be healthy.

Optimal Scanning Bandwidth Strategy Incorporating Uncertainty about Adversary's Characteristics

description: In this paper we investigate the problem of designing a spectrum scanning strategy to detect an intelligent Invader who wants to utilize spectrum undetected for his/her unapproved purposes. To deal with this problem we model the situation as two games, between a Scanner and an Invader, and solve them sequentially. The first game is formulated to design the optimal (in maxmin sense) scanning algorithm, while the second one allows one to find the optimal values of the parameters for the algorithm depending on parameters of the network. These games provide solutions for two dilemmas that the rivals face. The Invader's dilemma consists of the following: the more bandwidth the Invader attempts to use leads to a larger payoff if he is not detected, but at the same time also increases the probability of being detected and thus fined. Similarly, the Scanner faces a dilemma: the wider the bandwidth scanned, the higher the probability of detecting the Invader, but at the expense of increasing the cost of building the scanning system. The equilibrium strategies are found explicitly and reveal interesting properties. In particular, we have found a discontinuous dependence of the equilibrium strategies on the network parameters, fine and the type of the Invader's award. This discontinuity of the fine means that the network provider has to take into account a human/social factor since some threshold values of fine could be very sensible for the Invader, while in other situations simply increasing the fine has minimal deterrence impact. Also we show how incomplete information about the Invader's technical characteristics and reward (e.g. motivated by using different type of application, say, video-streaming or downloading files) can be incorporated into scanning strategy to increase its efficiency.

description: We provide a family of action-based distribution functions (DFs) for the double-power law family of densities often used to model galaxies. The DF itself is a double-power law in combinations of the actions, and reduces to the known limits in the case of a pure power-law at small and large radii. Our method enables the velocity anisotropy of the model to be tuned, and so the anisotropy in the inner and outer parts can be specified for the application in hand. We provide self-consistent DFs for the Hernquist and Jaffe models - both with everywhere isotropic velocity dispersions, and with kinematics that gradually becomes more radially anisotropic on moving outwards. We also carry out this exercise for a cored dark-matter model. These are tailored to represent dark haloes and elliptical galaxies respectively with kinematic properties inferred from simulations or observational data. Finally, we relax a cored luminous component within a dark matter halo to provide a self-consistent model of a dwarf spheroidal embedded in dark matter. The DFs provide us with non-rotating spherical stellar systems, but one of the virtues of working with actions is the relative ease with which such models can be converted into axisymmetry and triaxiality.

Associations Between County-Level Social Characteristics and Buprenorphine Waiver Receipt

Year: 2021

description: In recent years, the opioid epidemic has disparately impacted Black, Hispanic, and low socioeconomic status communities in the U.S., with Black and Hispanic populations also receiving the medication buprenorphine less frequently than White populations. These disparities in medication receipt may be connected to the spatial distribution of clinicians with Drug Enforcement Administration (DEA) buprenorphine waivers by these aforementioned sociodemographic characteristics on the area level. This spatial distribution may also be impacted by practitioner race or ethnicity, given evidence of pro-social sorting amongst racial/ethnic minority practitioner. Combining DEA Controlled Substances Act Registration Information, NC clinician licensure data, and county-level sociodemographic data from the American Community Survey, I investigated the association between area-level sociodemographic characteristics and DATA 2000 waiver receipt. Sociodemographic characteristics of behavioral health physicians’ practice county were not associated with DATA 2000 waiver receipt. However, a mixture of sociodemographic characteristics of a clinician’s practice county were associated with DATA 2000 receipt in the remainder of models. Additionally, the effect of Black and Hispanic area composition on waiver receipt differed between providers of different races/ethnicities. More work is needed to further explore the influence of area-level characteristics on opioid use disorder treatment, as well as methods to decrease these evident disparities across racial and socioeconomic lines.
Millions of Voices, Suddenly Silenced: Using Science Fiction to Understand Genocide

description: Sean Gallagher’s capstone project focused on the legal, social, and historical definitions of genocide and how this is constructed in the public imaginary. Through an analysis of Article Two of the Genocide Convention, Sean sought to understand how genocide is conflated with similar terms, such as mass killings, and how this has influenced its relationship to world events. He specifically studied how the Holocaust influenced modern definitions of genocide and blended the concepts of genocide and mass killing in the popular consciousness. To fully understand the underpinnings of the term genocide, Sean also utilized science fiction and the phenomenon of cognitive estrangement as a mechanism to understand genocide from the perspectives of perpetrators, victims, and bystanders, separating the legal concept from the popular (mass-murder focused) concept of genocide.
Universal instability for wavelengths below the ion Larmor scale

description: We demonstrate that the universal mode driven by the density gradient in a plasma slab can be absolutely unstable even in the presence of reasonable magnetic shear. Previous studies from the 1970s that reached the opposite conclusion used an eigenmode equation limited to $L_x \gg ρ_i$, where $L_x$ is the scale length of the mode in the radial direction, and $ρ_i$ is the ion Larmor radius. Here we instead use a gyrokinetic approach which does not have this same limitation. Instability is found for perpendicular wavenumbers $k_y$ in the range $0.7 \lesssim k_y ρ_i \lesssim 100$, and for sufficiently weak magnetic shear: $L_s / L_n \ge 17$, where $L_s$ and $L_n$ are the scale lengths of magnetic shear and density. Thus, the plasma drift wave in a sheared magnetic field may be unstable even with no temperature gradients, no trapped particles, and no magnetic curvature.

description: We consider indirect detection signals of atomic dark matter, with a massive dark photon which mixes kinetically with hypercharge. In significant regions of parameter space, dark matter remains at least partially ionized today, and dark atom formation can occur efficiently in dense regions, such as the centers of galactic halos. The formation of dark atoms is accompanied by emission of a dark photon, which can subsequently decay into Standard Model particles. We discuss the expected signal strength and compare it to that of annihilating dark matter. As a case study, we explore the possibility that dark atom formation can account for the observed 511 keV line and outline the relevant parameter space.

description: Nanostructures are commonly used for developing superhydrophobic surfaces. However, available wetting theoretical models ignore the effect of vacuum photon-modes alteration on van der Waals forces and thus on hydrophobicity. Using first-principle calculations, we show that superhydrophibicity of nanostructured surfaces is dramatically enhanced by vacuum photon-modes tuning. As a case study, wetting contact angles of a water droplet above a polyethylene nanostructured surface are obtained from the interaction potential energy calculated as function of the droplet-surface separation distance. This new approach could pave the way for the design of novel superhydrophobic coatings.

description: Sandra Kong’s capstone projects focused on advocating and bringing awareness to the political conflict in Myanmar following the military coup on February 1st, 2021. Along with other strong advocates and community members, Sandra worked with Global Movement for Myanmar Democracy (GM4MD), a youth-led grassroots organization coordinating international action among the Myanmar diaspora in support of Myanmar’s democracy, to create a centralized website platform for international campaigns and resources. While the website was created as a way of providing credibility and information about GM4MD’s projects, it quickly became a digital space providing real time and archival updates of the democracy movement such as snapshots of campaigns, political advocacy mechanisms, poetry and art, and breaking updates about fallen heroes. Moreover, the website’s central advocacy mission of positioning Myanmar’s political conflict as a global issue was critical in highlighting how the human right abuses (from women’s rights violations to endangerment of democracy to preventing access to healthcare) had impacts beyond Myanmar.

The Von Bertalanffy growth parameters CW∞/CL∞, k and t0 were estimated on the basis of Length-frequency modal progression analysis method. The values of CW∞ (mm), K (year-1) and t0 (year) would be, respectively, 95.61, 0.84 and -0.104 for males; 73.92, 1.11 and -0.149 for females in Carcinus aestuarii and, CL∞ (mm), K (year-1) and t0 (year) would be, respectively, 172.46, 0.68 and -0.147 for males; 147.05, 0.6 and -0.175 for females in Maja squinado.
These results were obtained, as the first attempt to study age and growth of these two crustaceans which will be of a great use for their eventual stock assessment studies.

description: Nahla Gedeon Achi’s capstone project focused on evaluating the successes and shortcomings of efforts to address forced labor in three industries with globally-integrated supply chains: palm oil, cattle ranching in Brazil, and prawn farming in Thailand. More specifically, Nahla looked to provide a comprehensive overview and analysis of a subset of existing strategies to address human trafficking within these varied industries. As a former research assistant for the Stanford Center for Ocean Solutions (COS), Nahla also tied her capstone project to existing initiatives put forth by COS and the Center for Human Rights and International Justice addressing slavery in tuna supply chains. Nahla hopes that her capstone project not only brings to light grave human rights issues within these industries, but also demonstrates how concerted efforts from governments, corporations, consumers, and communities everywhere will we be able to fully eliminate forced labor from all supply chains.

description: Constanza Hasselmann’s capstone project detailed the inception, implementation, and success of the “CS 184- Bridging Policy & Technology through Design” course at Stanford University. Originally starting out as an independent study course inspired by her interest in public technology and design, Constanza notes how this quickly pivoted from an independent study structure to a student lab titled Public Interest Technology (PIT) @ Stanford. Through adamant community and academic support, the PIT Lab fully launched CS 184 in Spring 2020. Partnering up with various organizations, project mentors, and faculty, CS 184 served as a project-based course meant to engage with the emerging topic of public interest technology and serve as a space where students from different academic backgrounds worked with external partner organizations at the nexus of digital technology and public policy. The goal of the class and the Lab is to ultimately reach new student audiences, engage with additional faculty and offer a project incubator. CS 184 remains an active Stanford course that aims to create an environment for a vibrant and interdisciplinary community of students, faculty, and external partners.

description: Uniaxial materials whose axial and tangential permittivities have opposite signs are referred to as indefinite or hyperbolic media. In such materials light propagation is unusual, leading to novel and often non-intuitive optical phenomena. Here we report infrared nano-imaging experiments demonstrating that crystals of hexagonal boron nitride (hBN), a natural mid-infrared hyperbolic material, can act as a "hyper-focusing lens" and as a multi-mode waveguide. The lensing is manifested by subdiffractional focusing of phonon-polaritons launched by metallic disks underneath the hBN crystal. The waveguiding is revealed through the modal analysis of the periodic patterns observed around such launchers and near the sample edges. Our work opens new opportunities for anisotropic layered insulators in infrared nanophotonics complementing and potentially surpassing concurrent artificial hyperbolic materials with lower losses and higher optical localization.

description: We study the homogenization of a novel microscopic tridomain system, allowing for a more detailed analysis of the properties of cardiac conduction than the classical bidomain and monodomain models. In (Acta Appl.Math. 179 (2022) 1--35), we detail this model in which gap junctions are considered as the connections between adjacent cells in cardiac muscle and could serve as alternative or supporting pathways for cell-to-cell electrical signal propagation. Departing from this microscopic cellular model, we apply the periodic unfolding method to derive the macroscopic tridomain model. Several difficulties prevent the application of unfolding homogenization results, including the degenerate temporal structure of the tridomain equations and a nonlinear dynamic boundary condition on the cellular membrane. To prove the convergence of the nonlinear terms, especially those defined on the microscopic interface, we use the boundary unfolding operator and a Kolmogorov--Riesz compactness's result.

Cruel and Unusual: Contesting Human Rights Violations in the American Carceral System
Creators: name: Newfeld, Lindsay
Publisher: name: Stanford Digital Repository
Year: 2022
Subjects: subject: Mass Incarceration
subject: Prisons--Law and legislation

description: Lindsay Newfeld’s capstone project investigated the lack of avenues available to incarcerated individuals in the United States who contest human rights violations occurring during their confinement. Her paper specifically focused on two available avenues for redress - prisoner grievance mechanisms and civil litigation and sought to answer (1) why these processes are so ineffective at producing remedies, and (2) the justification for denying this population effective access to the courts. Through interviews with formerly incarcerated individuals from Illinois, Lindsay gave insight to the depth, texture, and the perspectives of those who have experienced human rights violations while incarcerated. Motivated by her advocacy through various criminal justice and prison reform organizations, Lindsay hopes to understand prisoners’ rights through a human rights framework and create tangible change within the prison system.
Ax-Schanuel for the j-function

Publisher: name: arXiv
Year: 2014
Subjects: subject: Logic (math.LO)
subject: Number Theory (math.NT)
subject: FOS: Mathematics

description: In this paper we prove a functional transcendence statement for the j-function which is an analogue of the Ax-Schanuel theorem for the exponential function. It asserts, roughly, that atypical algebraic relations among functions and their compositions with the j-function are governed by modular relations.

Subjects: Race discrimination
Computer algorithms
Women
Asia

description: Current research has determined how additional factors like race, class, socioeconomic status, etc., all intersect to determine a woman’s experience in the world but what is lacking is how search engines and social media have perpetuated racist and sexist tropes against Asian women. The purpose of this research was to analyze the biases of platform algorithms in conjunction to keywords associated with Asian stereotypes. Both biased and unbiased searches will be conducted on platforms over a two-week period to explore these social concerns. This paper will analyze the results of the study and discuss the relations among the interdependencies of culture, society, and algorithms.
Entropic mechanisms with generalized scalar fields in the Ekpyrotic universe

subject: FOS: Physical sciences

description: For the Ekpyrotic universe, the entropic mechanisms with minimal couplings, which have been used to generate nearly scale invariant primordial perturbations, was proved to be unstable. To overcome this difficulty, some non-minimal coupling entropic models were proposed. In this paper we extend these studies to the cases where all the scalar fields have non-standard kinetic terms. We first prove that in these general cases, without non-minimal couplings the entropic models are still unstable. The condition for the stability conflicts with the requirement for achieving scale invariant perturbations. Then we study the non-minimal coupling models and show that at least for some simple cases these models are stable and able to generate the primordial perturbations consistent with current observations.

description: Software Process Improvement requires significant effort related not only to the identification of relevant issues and providing an adequate response to them but also to the implementation and adoption of the changes. Best practices provide recommendations to software teams on how to address the identified objectives in practice, based on aggregated experience and knowledge. In the paper, we present the GEANT experience and observations from the process of adopting the best practices and present the setting we have been using.
The Effect of Stricter State-level Firearm Legislation on Youth and Female Suicides
Creators: name: Flores, Alanna
Publisher: name: Stanford Digital Repository
Year: 2022
Subjects: subject: Firearms--Law and legislation

description: For her capstone project, Alanna Flores wrote a fascinating research paper that considered the effect of fourteen categories of state firearm laws enacted by different states at different times from 1991 through 2018. Her research further analyzed the causal connection between firearm laws, specifically background checks, child laws, trafficking regulation, possession for those convicted of domestic violence crimes, and gun-inflicted suicide rates of women and children. She hopes her work in the subject of firearm legislature will further an understanding of how laws work to preserve livelihood and consider the effectiveness of the government in protecting its people from harm, especially its most vulnerable communities.
Archiving psychiatric records: Exploring the ethics, privacy, and access issues of archiving mental health records

Psychiatric records
Privacy, Right of
Ethics

description: The purpose of this study was to understand how archivists perceive the value and ethics of acquiring and preserving psychiatric records despite cases where providing access to records is impossible due to privacy reasons. A study similar to this has not been located in the existing literature and therefore this study would have informed the archives field to how psychiatric hospital records are viewed. Member archivists and librarians of the Society of American Archivists would have been surveyed and four would have been interviewed as well to gain both breadth and depth on the research question. IRB approval was not received and therefore the study was not conducted.
Planetary systems and real planetary nebulae from planet destruction near white dwarfs

description: We suggest that tidal destruction of Earth-like and icy planets near a white dwarf (WD) might lead to the formation of one or more low-mass - Earth-like and lighter - planets in tight orbits around the WD. The formation of the new WD planetary system starts with a tidal break-up of the parent planet to planetesimals near the tidal radius of about 1Rsun. Internal stress forces keep the planetesimal from further tidal break-up when their radius is less than about 100km. We speculate that the planetesimals then bind together to form new sub-Earth - daughter-planets at a few solar radii around the WD. More massive planets that contain hydrogen supply the WD with fresh nuclear fuel to reincarnate its stellar-giant phase. Some of the hydrogen will be inflated in a large envelope. The envelope blows a wind to form a nebula that is later (after the entire envelope is lost) ionized by the hot WD. We term this glowing ionized nebula that originated from a planet a real planetary nebula (RPN). This preliminary study of daughter-planets from a planet (DPP) and the RPN scenarios are of speculative nature. More detail studies must follow to establish whether the suggested scenarios can indeed take place.
