description: Processes involving alpha particles and alpha-like nuclei comprise a major part of stellar nucleosynthesis and hypothesized mechanisms for thermonuclear supernovae. In an effort towards understanding alpha processes from first principles, we describe in this letter the first ab initio calculation of alpha-alpha scattering. We use lattice effective field theory to describe the low-energy interactions of nucleons and apply a technique called the adiabatic projection method to reduce the eight-body system to an effective two-cluster system. We find good agreement between lattice results and experimental phase shifts for S-wave and D-wave scattering. The computational scaling with particle number suggests that alpha processes involving heavier nuclei are also within reach in the near future.

Taming pseudo-fermion functional renormalization for quantum spins: Finite-temperatures and the Popov-Fedotov trick

description: The pseudo-fermion representation for $S=1/2$ quantum spins introduces unphysical states in the Hilbert space which can be projected out using the Popov-Fedotov trick. However, state-of-the-art implementation of the functional renormalization group method for pseudo-fermions have so far omitted the Popov-Fedotov projection. Instead, restrictions to zero temperature were made and absence of unphysical contributions to the ground-state was assumed. We question this belief by exact diagonalization of several small-system counterexamples where unphysical states do contribute to the ground state. We then introduce Popov-Fedotov projection to pseudo-fermion functional renormalization, enabling finite temperature computations with only minor technical modifications to the method. At large and intermediate temperatures, our results are perturbatively controlled and we confirm their accuracy in benchmark calculations. At lower temperatures, the accuracy degrades due to truncation errors in the hierarchy of flow equations. Interestingly, these problems cannot be alleviated by switching to the parquet approximation. We introduce the spin projection as a method-intrinsic quality check. We also show that finite temperature magnetic ordering transitions can be studied via finite-size scaling.

Perceived Causes of Loss of Vision and Areas of Potential Intervention in Glaucoma from Patient, Family Member, and Eye-Care Provider Perspectives: A Focus Group Study
Creators: name: Dzau, Jacqueline R.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: Glaucoma is a leading cause of blindness among older adult Americans. Despite the practice of evidence-based treatment for glaucoma there exists a high rate of failure to prevent loss of vision, even in patients receiving current glaucoma care. Non-compliance has received the greatest attention in the literature with respect to measurable factors associated with loss of vision in glaucoma. However, in order to improve glaucoma care and minimize preventable vision loss, further investigation is needed into the range of additional and underlying factors that may not be quantifiable in nature. This study used qualitative methods using procedures of focus groups to obtain original source data from glaucoma patients, their support systems (family members and friends), and glaucoma eye-care as to why vision loss occurs in glaucoma patients and what areas may be a point for intervention. The purpose of this study was to characterize potentially new content areas and expand upon those previously suggested for intervention or additional investigation with respect to factors associated with vision loss identified by these focus groups.
Searching for $C\!P$ violation through two-dimensional angular distributions in four-body decays of bottom and charmed baryons

description: It is proposed to search for $C\!P$ violation through the two-fold angular distributions in the four-body decays of bottom and charmed hadrons. The two polar angles in the two-fold angular distributions are correlated, to which the interferences of intermediate resonances are one important origin. These interferences will leave tracks in the two-fold angular distributions, with which the $C\!P$ violation can be studied. Special attention is paid to the case when all the intermediate resonances are different, which is unique to four-body decays. It is suggested to look for $C\!P$ violation in four-body decays such as $Λ_b^0\to p π^-π^+π^-$ through the analysis of the two-fold angular distributions. The method proposed in this paper is also widely applicable to other four-body decays processes.

description: Interplanetary (IP) shocks are fundamental building blocks of the heliosphere, and the possibility to observe them \emph{in-situ} is crucial to address important aspects of energy conversion for a variety of astrophysical systems. Steepened waves known as shocklets are known to be important structures of planetary bow shocks, but they are very rarely observed related to IP shocks. We present here the first multi-spacecraft observations of shocklets observed by upstream of an unusually strong IP shock observed on November 3rd 2021 by several spacecraft at L1 and near-Earth solar wind. The same shock was detected also by radially aligned Solar Orbiter at 0.8 AU from the Sun, but no shocklets were identified from its data, introducing the possibility to study the environment in which shocklets developed. The Wind spacecraft has been used to characterise the shocklets, associated with pre-conditioning of the shock upstream by decelerating incoming plasma in the shock normal direction. Finally, using the Wind observations together with ACE and DSCOVR spacecraft at L1, as well as THEMIS B and THEMIS C in the near-Earth solar wind, the portion of interplanetary space filled with shocklets is addressed, and a lower limit for its extent is estimated to be of about 110 $R_E$ in the shock normal direction and 25 $R_E$ in the directions transverse to the shock normal. Using multiple spacecraft also reveals that for this strong IP shock, shocklets are observed for a large range of local obliquity estimates (9-64 degrees).

description: New dark sectors consisting of exotic fields that couple only very feebly to the Standard Model (SM) have strong theoretical motivation and may be relevant to explaining the abundance of dark matter (DM). An important question for such sectors is how they connect to the SM. For a dark sector with a new gauge interaction, a natural connection arises from heavy vector-like fermions charged under both the visible and dark gauge groups. The gauge charges of such fermions imply that one or more of them is stable in the absence of additional sources of dark symmetry breaking. A generic challenge for such connectors is that they can produce too much dark matter or interact too strongly with nuclei if they were ever thermalized in the early universe. In this paper we study this challenge in a simple connector theory consisting of new vector-like electroweak doublet and singlet fermions that also transform under the fundamental representation of a new (Abelian) gauge force, and we show that these connectors in their minimal form are almost always ruled out by existing direct DM searches. To address this challenge, we investigate two solutions. First, we study mitigating scattering on nuclei by introducing a Majorana mass term for the singlet. And second, we investigate a mixing with SM leptons that allows the connectors to decay while remaining consistent with cosmological tests and searches for charged lepton flavor violation. Both solutions rely on the presence of a dark Higgs field with a specific charge.

description: We characterize niobium-based lateral Superconductor (S) - Normal metal (N) - Superconductor weak links through low-temperature switching current measurements and tunnel spectroscopy. We fabricate the SNS devices in two separate lithography and deposition steps, combined with strong argon ion cleaning before the normal metal deposition in the last step. Our SNS weak link consists of high-quality sputtered Nb electrodes that are contacted with evaporated Cu. The two-step fabrication flow enables great flexibility in the choice of materials and pattern design. A comparison of the temperature-dependent equilibrium critical supercurrent with theoretical predictions indicates that the quality of the Nb-Cu interface is similar to that of evaporated Al-Cu weak links. Aiming at increased sensitivity, range of operation temperatures, and thermal isolation, we investigate how these SNS structures can be combined with shadow-evaporated aluminum tunnel junctions for sensor applications that utilize the superconducting proximity effect. To this end, we demonstrate a hybrid magnetic flux sensor based on a Nb-Cu-Nb SNS junction, where the phase-dependent normal metal density of states is probed with an Al tunnel junction.

A Cystectomy Risk Calculator and Assessment Based on NSQIP Data
Creators: name: Wang, Nancy
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2013

description: ABSTRACT Background: The American Cancer Society estimates that 72,570 people will be diagnosed with bladder cancer and 15,210 people will die from the disease in 2013. Radical cystectomy has been the standard treatment for decades, but the procedure is associated with significant morbidity and mortality. Currently, there are no preoperative tools which can help assess patient postoperative risk. In this study, we address this need by creating a cystectomy risk calculator based on analysis of data from the American College of Surgeons’ National Surgical Quality Improvement Program (NSQIP). Methods: The NSQIP database was queried for cystectomy cases for bladder cancer between 2005 and 2011. Fifty preoperative patient parameters and 74 postoperative outcomes were assessed, but only 32 independent preoperative variables had adequate sample size and were included in the stepwise logistic regression models for overall mortality and morbidity. Statistically significant variables were weighed and used to create a cystectomy risk calculator. Results: From the NSQIP database, 1095 cystectomy cases were identified. High preoperative BUN levels and previous PCI were predictive for increased postop morbidity risk. Previous cardiac surgery was associated with lower postop morbidity risk. Chemotherapy treatment within 30 days of surgery was associated with lower postop morbidity risk but increased postop mortality risk. Chronic steroid treatment and high preoperative WBC lab values were also associated with increased postop mortality risk. Conclusion: This study identifies significant predictive preoperative variables that inform postoperative complications following cystectomy. The cystectomy risk calculator created gives physicians and patients a more precise estimation of individual risks of morbidity and mortality associated with the procedure.

description: Core-collapse supernovae (CCSNe) emit powerful gravitational waves (GWs). Since GWs emitted by a source contain information about the source, observing GWs from CCSNe may allow us to learn more about CCSNs. We study if it is possible to infer the iron core mass from the bounce and early ring-down GW signal. We generate GW signals for a range of stellar models using numerical simulations and apply machine learning to train and classify the signals. We consider an idealized favourable scenario. First, we use rapidly rotating models, which produce stronger GWs than slowly rotating models. Second, we limit ourselves to models with four different masses, which simplifies the selection process. We show that the classification accuracy does not exceed ~70%, signifying that even in this optimistic scenario, the information contained in the bounce and early ring-down GW signal is not sufficient to precisely probe the iron core mass. This suggests that it may be necessary to incorporate additional information such as the GWs from later post-bounce evolution and neutrino observations to accurately measure the iron core mass.

description: We present paper six of the NIRSPEC Brown Dwarf Spectroscopic Survey, an analysis of multi-epoch, high-resolution (R~20,000) spectra of 25 field dwarf systems (3 late-type M dwarfs, 16 L dwarfs, and 6 T dwarfs) taken with the NIRSPEC infrared spectrograph at the W. M. Keck Observatory. With a radial velocity precision of ~2 km/s, we are sensitive to brown dwarf companions in orbits with periods of a few years or less given a mass ratio of 0.5 or greater. We do not detect any spectroscopic binary brown dwarfs in the sample. Given our target properties, and the frequency and cadence of observations, we use a Monte Carlo simulation to determine the detection probability of our sample. Even with a null detection result, our 1 sigma upper limit for very low mass binary frequency is 18%. Our targets included 7 known, wide brown dwarf binary systems. No significant radial velocity variability was measured in our multi-epoch observations of these systems, even for those pairs for which our data spanned a significant fraction of the orbital period. Specialized techniques are required to reach the high precisions sensitive to motion in orbits of very low-mass systems. For eight objects, including six T dwarfs, we present the first published high-resolution spectra, many with high signal to noise, that will provide valuable comparison data for models of brown dwarf atmospheres.

Development of a Community Transitions of Care Program
Creators: name: Barmer, Katherine
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2012

description: When patients suffer an acute health event in a community, they may enter multiple care settings and have several health care providers. As healthcare continues to evolve, patients are moved in and out of hospitals at a much faster pace, often leaving room for information to get lost and discharge plans to be inadequate. Hospitals are also encouraged financially to provide their patients with quality care and to do everything possible to prevent them from being readmitted soon after discharge. To ensure that patients transition smoothly from the hospital into the community, a collaborative, multidisciplinary effort is crucial. A public health nurse can help build and strengthen transitional care programs within the hospital and establish partnerships outside of the hospital to improve care transitions across the community. Key words: care transitions, patient-centered care, readmission

description: The interplay of phase separation and dynamical arrest can lead to the formation of gels and glasses, which is relevant for such diverse fields as hard and soft condensed matter physics, materials science, food engineering and pharmaceutical industry. Here, the non-equilibrium states as well as the interactions of globular proteins are analyzed. Lysozyme in brine is chosen as a model system with short-range attractions. The metastable gas-liquid binodal and the dynamical arrest line as well as the second virial coefficient $B_2$ have been determined for various solution conditions by cloud-point measurements, optical microscopy, centrifugation experiments and light scattering. If temperature is expressed in terms of $B_2$, the binodals obtained under various conditions fall onto a master curve, as suggested by the extended law of corresponding states. Arrest lines for different salt concentrations overlap within experimental errors, whereas they do not overlap if the temperature axis is replaced by $B_2$. This indicates that the binodals are not sensitive to the details of the potential, but can be described by one integral parameter, i.e. $B_2$, whereas the arrest line appears governed by its attractive part. The experimental findings are supported by numerical results of the non-equilibrium self-consistent generalized Langevin equation theory.
Ab initio study of metastable occupation of tetrahedral sites in palladium hydrides and its impact on superconductivity

description: A recent experimental work on palladium hydrides suggested that metastable structures with hydrogen atoms occupying tetrahedral sites could lead to superconductivity above 50 K, a huge increase compared to the 10 K critical temperature of the stable structure with all hydrogen atoms occupying octahedral sites. By generating many structures with hydrogen atoms randomly occupying the octahedral and tetrahedral sites of the face-centered cubic lattice and calculating their energy at different theoretical levels from first principles, we determine that metastable structures with partial or full occupation of tetrahedral sites are possible, even when the ionic quantum zero-point energy and anharmonicity are included in the calculations. Anharmonicity is crucial in palladium hydrides when hydrogen atoms occupy octahedral sites and, in fact, makes the structure with full octahedral occupation the ground state. Despite the metastable existence of structures with full or partial tetrahedral sites occupation, the superconducting critical temperature is reduced with the number of tetrahedral sites occupied. Our calculations discard that the occupation of tetrahedral sites can increase the critical temperature in palladium hydrides.
Reinforcement-learning-based actuator selection method for active flow control

description: This paper addresses the issue of actuator selection for active flow control by proposing a novel method built on top of a reinforcement learning agent. Starting from a pre-trained agent using numerous actuators, the algorithm estimates the impact of a potential actuator removal on the value function, indicating the agent's performance. It is applied to two test cases, the one-dimensional Kuramoto-Sivashinsky equation and a laminar bi-dimensional flow around an airfoil at Re=1000 for different angles of attack ranging from 12 to 20 degrees, to demonstrate its capabilities and limits. The proposed actuator-sparsification method relies on a sequential elimination of the least relevant action components, starting from a fully developed layout. The relevancy of each component is evaluated using metrics based on the value function. Results show that, while still being limited by this intrinsic elimination paradigm (i.e. the sequential elimination), actuator patterns and obtained policies demonstrate relevant performances and allow to draw an accurate approximation of the Pareto front of performances versus actuator budget.

For such systems, the possibility of obtaining static spherically symmetric solutions describing compact massive central objects enclosed by high-redshift surfaces (black-hole-like configurations) is studied. Using the standard thin accretion disk model, we exhibit potentially observable differences allowing to distinguish the mixed systems from ordinary black holes with the same masses.

description: While large scale primordial non-Gaussianity is strongly constrained by present-day data, there are no such constraints at Mpc scales. Here we investigate the effect of significant small-scale primordial non-Gaussianity on structure formation and the galaxy formation process with collisionless simulations: specifically, we explore four different types of non-Gaussianities. All of these prescriptions lead to a distinct and potentially detectable feature in the matter power spectrum around the non-linear scale. The feature might have interesting consequences for the $S_8$ tension. We then show in particular that a negatively-skewed distribution of the potential random field, hence positively skewed in terms of overdensities, with $f_{\rm NL}$ of the order of 1000 at these scales, implies that typical galaxy-sized halos reach half of their present-day mass at an earlier stage and have a quieter merging history at $z<3$ than in the Gaussian case. Their environment between 0.5 and 4 virial radii at $z=0$ is less dense than in the Gaussian case. This quieter history and less dense environment has potentially interesting consequences in terms of the formation of bulges and bars. Moreover, we show that the two most massive subhalos around their host tend to display an interesting anti-correlation of velocities, indicative of kinematic coherence. All these hints will need to be statistically confirmed in larger-box simulations with scale-dependent non-Gaussian initial conditions, followed by hydrodynamical zoom-in simulations to explore the detailed consequences of small-scale non-Gaussianities on galaxy formation.

description: The Triple Aim recommends that improvements to the US health care delivery system focus on the three interdependent goals of high quality care, reduced per capita cost and improved population health (Berwick, Nolan, & Whittington, 2008). Significant challenges exist to accomplish these improvements; however, Berwick, Nolan and Whittington (2008) identify some promising innovations that have the potential to disrupt the current primary health care service model. One of the innovations recognized is the retail clinic model of health care delivery. The number of retail clinics has increased rapidly since the first clinic opened in 2000. Retail clinics offer health care services for diagnoses of specific acute illnesses, as well as vaccinations and preventive care, typically within a retail setting such as Walmart, Target, pharmacy or grocery store. The clinics are sometimes referred to as convenient care clinics to reflect their patient-centric access to care - no appointment is required, weekend and evening hours are offered, and wait times are shorter than at traditional health care facilities. One approach to externally evaluate the performance of retail clinics is to examine them within the triple aim framework of quality of care, per capita cost and population health. Metrics to evaluate health care services for each triple aim goal have been recommended by the Institute for Healthcare Improvement (Stiefel & Nolan, 2012). The specific measures used by individual organizations are determined by the objectives of the organization, available resources and the availability of data. This paper will discuss the metrics available to retail clinics and review published data for these metrics to determine the impact of retail clinic health care services on the triple aim goals.
A Parameterized Algorithm for Bounded-Degree Vertex Deletion

description: The $d$-bounded-degree vertex deletion problem, to delete at most $k$ vertices in a given graph to make the maximum degree of the remaining graph at most $d$, finds applications in computational biology, social network analysis and some others. It can be regarded as a special case of the $(d+2)$-hitting set problem and generates the famous vertex cover problem. The $d$-bounded-degree vertex deletion problem is NP-hard for each fixed $d\geq 0$. In terms of parameterized complexity, the problem parameterized by $k$ is W[2]-hard for unbounded $d$ and fixed-parameter tractable for each fixed $d\geq 0$. Previously, (randomized) parameterized algorithms for this problem with running time bound $O^*((d+1)^k)$ are only known for $d\leq2$. In this paper, we give a uniform parameterized algorithm deterministically solving this problem in $O^*((d+1)^k)$ time for each $d\geq 3$. Note that it is an open problem whether the $d'$-hitting set problem can be solved in $O^*((d'-1)^k)$ time for $d'\geq 3$. Our result answers this challenging open problem affirmatively for a special case. Furthermore, our algorithm also gets a running time bound of $O^*(3.0645^k)$ for the case that $d=2$, improving the previous deterministic bound of $O^*(3.24^k)$.

description: Objectives: To determine if an association exists in Durham County between time the North Carolina Medicaid care management program (CCNC) has been in place and changes in service utilization patterns among asthmatic children, and to assess the relationship between program duration and racial disparities. Methods: CCNC program years 2000, 2001, 2002 were evaluated. Individuals aged 0-18 with an asthma Medicaid claim (ICD9 code 493.xx) emolled in CCNC were eligible. Incidence rate ratios and likelihood rates were calculated for outpatient, ED and hospital use, controlling for age, race, gender, pregnancy, welfare status and person-months. Analysis was also done with sample stratified by race. Results: Compared to 2000, the adjusted rate of outpatient use was 1.317 times greater in 2001 (p=0.007) and 1.216 times greater in 2002 (p=0.032). Compared to 2000, the adjusted rate of emergency department use was 1.428 times greater in 2001 (p=0.034), 1.693 times greater in 2002 (p=0.001). There were no significant differences in inpatient utilization by time period or race. Although African American and Hispanic outpatient use increased more than Caucasians over time, an initial disparity remained statistically significant, with Caucasians being more likely to use ambulatory care than either race. African Americans increased their ED use over time, but there were no statistically significant disparities in ED use. Conclusions: CCNC emollee use of ambulatory care increased from year 2000 to 2002; however, this utilization began and remained unequal among races. ED use rose, rather than decreasing. Evalnation across more program years is necessary to determine the long-term effect on ED utilization and cost.

description: The lightlike limit of boosted black hole solutions with one angular momentum is considered for $D \geq4$ dimensions. The boost is performed parallel to the angular momentum and the lightlike limit is done by means of perturbative expansions. We shown that for $D=4$ and $D> 5$ the lightlike limit cannot be extended inside the ring singularity. Then, for $D = 5$ we discuss the arising of trapped surfaces in the head-on collision. We find that, inside the validity of the perturbative analysis we do, a trapped surface with topology $\mathbb R \times \mathbb S_1 \times\mathbb S_1$ seems to appear over the past light cone of the collision below a critical value $a_c$ of the Kerr parameter $a$.
