description: We consider a Sklyanin algebra S with 3 generators, which is the quadratic algebra over a field k with three generators x,y,z given by three relations pxy+qyx+rzz=0, pyz+qzy+rxx=0 and pzx+qxz+ryy=0, where p,q,r are parameters from the fileld k. This class of algebras enjoyed much of attention, in particular, using tools from algebraic geometry, Feigin & Odesskii, and Artin, Tate & Van den Berg, showed that if at least two of the parameters p, q and r are non-zero and at least two of three numbers p^3,q^3 and r^3 are distinct, then S is Koszul and has the same Hilbert series as the algebra of commutative polynomials in three variables. It became commonly accepted, that it is impossible to achieve the same objective by purely algebraic and combinatorial means, like the Groebner basis technique. The main purpose of this paper is to trace combinatorial meaning of the properties of Sklyanin algebras, such as Koszulity, PBW, PHS, Calabi-Yau, and to give a new constructive proof of the above facts due to Artin, Tate and Van den Bergh. Further, we study a wider class of Sklyanin algebras, namely the situation when all parameters of relations could be different. This class called generalized Sklyanin algebras. We classify up to isomorphism genralized Sklyanin algebras with polynomial Hilbert series. We show that generalized Slyanin algebras in general position have the Golod-Shafarevich Hilbert series (with exception of the case of the field with two elements).

Creating Smaller Silos: An Analysis of North Carolina’s Journey to Chronic Disease Program Integration
Creators: name: Reese, April
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: This case study describes North Carolina’s initial efforts at chronic disease program integration, an emerging trend for blending individual categorical disease and risk factor programs into a single chronic disease prevention and control unit. In December 2007, states receiving substantial grant funds to prevent chronic disease through categorical programs were offered the chance to apply for participation in a Centers for Disease Control and Prevention (CDC) demonstration project to “increase synergy, reach and desired health outcomes in selected categorical programs” (J. Collins, personal communication, December 17, 2007). Over the three-year period which begins January 1, 2009, four states, including North Carolina, will enter into a negotiated agreement that gives them the freedom to share financial and human resources in ways that were not previously allowed. This paper describes the multi-year process that North Carolina forged in preparation for the negotiated agreement. This paper also includes a review of the lessons learned from previous multi-agency collaborative efforts that helped to guide North Carolina’s process. It includes recommendations for capturing lessons learned in a way that other states can replicate as well as indicators of progress towards the goal of integration.

description: In the archive of the Ground Wide Angle Camera (GWAC), we found 43 white light flares from 43 stars, among which, three are sympathetic or homologous flares, and one of them also has a quasi-periodic pulsation with a period of $13.0\pm1.5$ minutes. Among these 43 flare stars, there are 19 new active stars and 41 stars that have available TESS and/or K2 light curves, from which we found 931 stellar flares. We also obtained rotational or orbital periods of 34 GWAC flare stars, of which 33 are less than 5.4 days, and ephemerides of three eclipsing binaries from these light curves. Combining with low resolution spectra from LAMOST and the Xinglong 2.16m telescope, we found that $L_{\rm Hα}/L_{\rm bol}$ are in the saturation region in the rotation-activity diagram. From the LAMOST medium-resolution spectrum, we found that Star \#3 (HAT 178-02667) has double H$α$ emissions which imply it is a binary, and two components are both active stars. Thirteen stars have flare frequency distributions (FFDs) from TESS and/or K2 light curves. These FFDs show that the flares detected by GWAC can occur at a frequency of 0.5 to 9.5 yr$^{-1}$. The impact of flares on habitable planets was also studied based on these FFDs, and flares from some GWAC flare stars may produce enough energetic flares to destroy ozone layers, but none can trigger prebiotic chemistry on their habitable planets.

description: We study the stability of special, stratified solutions of a 3d Boussinesq system describing an incompressible, inviscid 3d fluid with variable density (or temperature, depending on the context) under the effect of a uni-directional gravitational force. The behavior is shown to depend on the properties of an anisotropic dispersive operator with weak decay in time. However, the dispersive decay also depends on the strength of the gravity in the system and on the profile of the stratified solution, whose stability we study. We show that as the strength of the dispersion in the system tends to infinity, the 3d system of equations tends to a stratified system of 2d Euler equations with stratified density.

description: The spatial distribution of galaxies and their gravitational lensing signal offer complementary tests of galaxy formation physics and cosmology. However, their synergy can only be fully exploited if both probes are modelled accurately and consistently. In this paper, we demonstrate that this can be achieved using an extension of Subhalo Abundance Matching, dubbed SHAMe. Specifically, we use mock catalogues built from the TNG300 hydrodynamical simulation to show that SHAMe can simultaneously model the multipoles of the redshift-space galaxy correlation function and galaxy-galaxy lensing, without noticeable bias within the statistical sampling uncertainties of a SDSS volume and on scales r = [0.6-30] Mpc/h. Modelling the baryonic processes in galaxy-galaxy lensing with a baryonification scheme allows SHAMe's range of validity to be extended to r = [0.1-30] Mpc/h. Remarkably, our model achieves this level of precision with just five free parameters beyond those describing the baryonification model. At fixed cosmology, we find that galaxy-galaxy lensing provides a general consistency test but little additional information on galaxy modelling parameters beyond that encoded in the redshift-space multipoles. It does, however, improve constraints if only the projected correlation function is available, as in surveys with only photometric redshifts. We expect SHAMe to have a higher fidelity across a wider range of scales than more traditional methods such as Halo Occupation Distribution modelling. Thus it should provide a significantly more powerful and more robust tool for analysing next-generation large-scale surveys.

description: Objective: To examine the basic psychometric features of a modified version of the Coma Recovery Scale-Revised (CRS-R) for use in young children with disorders of consciousness (DoC). Method: The CRS-R was modified to create the Coma Recovery Scale for Pediatrics (CRS-P) and administered to 33 typically developing children (8–59 months). Total scores, subtest scores, and inter-rater reliability were evaluated. Performance on the two items representing emergence to conscious state (CS) – functional object use (FOU) and functional communication (FC) was examined across the age range. Results: Inter-rater reliability of CRS-P subscale scores was adequate (Kw = .87–1.00). All 4-year-olds, 75% of 3-year-olds, 10% of 2-year-olds, and 0% <2 years scored at the CRS-P ceiling. Total and subtest scores were strongly correlated with age as were the two behaviors representing emergence to CS (FOU, FC) – all children >12 months and none <12 months of age met criteria for FOU; all children ≥3 years, 20% between 2 and <3 years, and none <2 years met criteria for FC. Conclusions: The CRS-P is appropriate for use in children as young as 12 months of age, with a strong association between performance and age at administration. The CRS-P also captures emergence to CS, a key clinical milestone.
Rarefied Broad-Line Regions in Active Galactic Nuclei: Anomalous Responses in Reverberation Mapping and Implications for Weak Emission-Line Quasars

description: Reverberation mapping (RM) is a widely-used method for probing the physics of broad-line regions (BLRs) in active galactic nuclei (AGNs). There are increasing preliminary evidences that the RM behaviors of broad emission lines are influenced by BLR densities, however, the influences have not been investigated systematically from theoretical perspective. In the present paper, we adopt locally optimally emitting cloud model and use CLOUDY to obtain the one-dimensional transfer functions of the prominent UV and optical emission lines for different BLR densities. We find that the influences of BLR densities to RM behaviors have mainly three aspects. First, rarefied BLRs (with low gas densities) may show anomalous responses in RM observations. Their emission-line light curves inversely response the variations of continuum light curves, which may have been observed in some UV RM campaigns. Second, the different BLR densities in AGNs may result in correlations between the time lags and equivalent widths of emission lines, and may contribute to the scatters of the radius-luminosity relationships. Third, the variations of BLR densities may explain the changes of time lags in individual objects in different years. Some weak emission-line quasars (WLQs) are probably extreme cases of rarefied BLRs. We predict that their RM observations may show the anomalous responses.

description: The instability of an atomic clock is characterized by the Allan variance, a measure widely used to describe the noise of frequency standards. We provide an explicit method to find the ultimate bound on the Allan variance of an atomic clock in the most general scenario where N atoms are prepared in an arbitrarily entangled state and arbitrary measurement and feedback are allowed, including those exploiting coherences between succeeding interrogation steps. While the method is rigorous and general, it becomes numerically challenging for large N and long averaging times.

description: We study the global approximate controllability properties of a one dimensional semilinear reaction-diffusion equation governed via the coefficient of the reaction term. It is assumed that both the initial and target states admit no more than finitely many changes of sign. Our goal is to show that any target state $ u^*\in H_0^1 (0,1)$, with as many changes of sign in the same order as the given initial data $ u_0\in H^1_0(0,1)$, can be approximately reached in the $ L^2 (0,1)$-norm at some time $T>0$. Our method employs shifting the points of sign change by making use of a finite sequence of initial-value pure diffusion problems.

description: 222 hot subdwarf stars were identified with LAMOST DR8 spectra, among which 131 stars show composite spectra and have been decomposed, while 91 stars present single-lined spectra. Atmospheric parameters of all sample stars were obtained by fitting Hydrogen (H) and Helium (He) line profiles with synthetic spectra. Two long-period composite sdB binaries were newly discovered by combining our sample with the non-single star data from Gaia DR3. One of the new systems presents the highest eccentricity (i.e., 0.5 +/- 0.09) among known wide sdB binaries, which is beyond model predictions. 15 composite sdB stars fall in the high probability binary region of RUWE-AEN plane, and deserve priority follow-up observations to further study their binary nature. A distinct gap is clearly presented among temperatures of cool companions for our composite-spectra sample. But we could not come to a conclusion whether this feature is connected to the formation history of hot subdwarf stars before their binary natures are confirmed.

Renewal equations for single-particle diffusion through a semipermeable interface

Publisher: name: arXiv
Year: 2022
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: Diffusion through semipermeable interfaces has a wide range of applications, ranging from molecular transport through biological membranes to reverse osmosis for water purification using artificial membranes. At the single-particle level, one-dimensional diffusion through a barrier with constant permeability $κ_0$ can be modeled in terms of so-called snapping out Brownian motion (BM). The latter sews together successive rounds of partially reflecting BMs that are restricted to either the left or right of the barrier. Each round is killed (absorbed) at the barrier when its Brownian local time exceeds an exponential random variable parameterized by $κ_0$. A new round is then immediately started in either direction with equal probability. It has recently been shown that the probability density for snapping out BM satisfies a renewal equation that relates the full density to the probability densities of partially reflected BM on either side of the barrier. Moreover, generalized versions of the renewal equation can be constructed that incorporate non-Markovian, encounter-based models of absorption. In this paper we extend the renewal theory of snapping out BM to single-particle diffusion in bounded domains and higher spatial dimensions. We also consider an example of an asymmetric interface in which the directional switching after each absorption event is biased. Finally, we show how to incorporate an encounter-based model of absorption for single-particle diffusion through a spherically symmetric interface. We find that, even when the same non-Markovian model of absorption applies on either side of the interface, the resulting permeability is an asymmetric time-dependent function with memory. Moreover, the permeability functions tend to be heavy-tailed.

Nonleptonic decays of $Ξ_{cc}\to Ξ_c π$ with $Ξ_c-Ξ_c'$ mixing

description: Aiming on testing the $Ξ_c-Ξ_c'$ mixing, we study the decays of $Ξ_{cc}\to Ξ_c π$ with $Ξ_{cc} = (Ξ_{cc}^{++} , Ξ_{cc} ^+ )$, $Ξ_c = (Ξ_c^{(\prime)+},Ξ_c^{(\prime)0})$ and $π= (π^+ , π^0)$. The soft-meson limit is considered along with the pole model, and the baryon matrix elements are evaluated by the bag model with and without removing the center-of-mass motion (CMM). We find that the four-quark operator matrix elements are about twice larger once the unwanted CMM is removed. We obtain that ${\cal R} = {\cal B}(Ξ_{cc}^+ \to Ξ_c^{\prime +} π^+ )/ {\cal B}(Ξ_{cc}^+ \to Ξ_c^{ +} π^+ ) = 0.87^{+0.17}_{-0.11} $ and $1.45$ with and without removing the CMM, where the former is close to the lower bound and the later is well consistent with ${\cal R} = 1.41 \pm 0.17 \pm 0.10$ measured at LHCb. In addition, we show that after including the mixing, the up-down asymmetry of $α( Ξ_{cc}^+ \to Ξ_c^{(\prime)0 } π^+)$ flips sign. Explicitly, we obtain that $α(Ξ_{cc}^{+} \to Ξ_c^{\prime +} π^0) = 0.52$ and $α(Ξ_{cc}^{+} \to Ξ_c^{ 0 } π^+) = 0.31$ with and without the CMM corrections, respectively, which are all negative if the mixing is absence. As a bonus, a positive value of $α(Ξ_{cc}^{+} \to Ξ_c^{\prime 0} π^+)$ in experiments can also serve as the evidence of the $W$-exchange contributions.

A Framework for Improving Preconception Health Care Interventions Using Continuous Quality Improvement
Creators: name: Dye, Ariana

description: Continuous Quality Improvement (CQI) is an organizational management process used to continually monitor and implement improvement processes. CQI is distinguished by a focus on customer satisfaction, systematic process, and process measurement and decision making. The Infant Mortality Rate (IMR) is a leading health indicator used in public health that is reflective of maternal health and socioeconomic inequalities such as access to health care. IMRs and racial and ethnic disparities among them have been a public health priority for decades. Research for effective, evidence-based methods to reduce overall IMRs and disparities is on-going. Preconception care (PCC) is a leading public health intervention based on the Life Course approach, which aims to improve the health of all women capable of reproducing, therefore improving birth outcomes and reducing IMRs. Despite the effectiveness of CQI in other industries and promising improvements in some CQI public health interventions, CQI has yet to be applied to PCC practices with any form of standardization or consistency. This paper will explore the application of CQI in public health and in PCC, determine if guidelines for applying CQI to PCC exist, and suggest a framework for applying CQI to PCC interventions at the state and local level.

description: Instantaneous features of three-dimensional velocity fields are most directly visualized via streamsurfaces. It is generally unclear, however, which streamsurfaces one should pick for this purpose, given that infinitely many such surfaces pass through each point of the flow domain. Exceptions to this rule are vector fields with a nondegenerate first integral whose level surfaces globally define a continuous, one-parameter family of streamsurfaces. While generic vector fields have no first integrals, their vortical regions may admit local first integrals over a discrete set of streamtubes, as Hamiltonian systems are known to do over Cantor sets of invariant tori. Here we introduce a method to construct such first integrals approximately from velocity data, and show that their level sets indeed frame vortical features of the velocity field in examples in which those features are known from Lagrangian analysis. Moreover, we test our method in numerical data sets, including a flow inside a V-junction and a turbulent channel flow. For the latter, we propound an algorithm to pin down the most salient barriers to momentum transport up to a given scale providing a way out of the occlusion conundrum that typically accompanies other vortex visualization methods.

The U.S. Global Gag Rule and its Effect on HIV/AIDS Services in Africa
Creators: name: Frankel, Nina
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: The U.S. government's Mexico City Policy denies U.S. international family planning funding to foreign non-governmental organizations (NGOs) that provide abortion services, provide counseling or referrals regarding abortion, or participate in political discourse or lobbying on the topic, even if they use their own funds to do so. This restriction, known as the Global Gag Rule (GGR) because it restricts speech and would be unconstitutional if applied to U.S. organizations, officially pertains only to family planning monies allocated by the U.S. Agency for International Development (USAID). While most U.S. international HIV/AIDS funding has been specifically exempt from the GGR, the restriction has nonetheless impacted HIV/AIDS services in a number of ways, to the detriment of the prevention and treatment of the disease. This is because family planning and HIV/AIDS service delivery tend to be integrated in developing countries and also because there has been confusion over the strength of the exemption itself. International NGO representatives and health-care professionals in developing countries are often not aware of the exceptions to the GGR, or they feel pressured to avoid all activities that may be associated with abortion so as to not risk loss of funding. This has resulted in a chilling effect on reproductive health services beyond the scope of those that are abortion-related. In sub-Saharan Africa, where the unmet need for contraceptive and other reproductive health services remains unacceptably high and where the HIV/AIDS pandemic has been most severe and devastating, the GGR has negatively impacted both areas of reproductive health. It has penalized hundreds of organizations, and the people they serve, not just by denying the women's right to control their reproduction through abortion, but also in effect reducing their access to family planning and other reproductive health services, including the prevention and treatment of HIV/AIDS. This rule has had a detrimental impact on service delivery, not only of family planning and other reproductive health services, but also of HIV/AIDS services, especially to the most vulnerable populations and those who need these services the most.
Holographic mutual information in global Vaidya-BTZ spacetime

description: We investigate the evolution of the mutual information between two spatial subsystems in a compact 1+1 dimensional CFT after a quantum quench. To this end, we use the dual holographic process, given by the 2+1 dimensional Vaidya-BTZ spacetime in global coordinates, which describes the collapse of a spherically symmetric null shell. So, we first discuss the spacelike geodesic structure of this geometry and then we present the various behaviors of the holographic mutual information observed in this case. We also consider the analogous process in the adiabatic limit and compare these two cases from a geometrical point of view.

description: We used stable isotopes to help assess ecohydrological partitioning in different types of urban green space in the city of Berlin. We focused particularly on the role of the near-surface of soils as a crucial interface that determines shallow subsurface (“non-Hortonian”) flows and water cycling in cities. Grassland soils tended to be wetter than soils under continuous urban tree cover, and areas around individual trees in parks or on streets. This is consistent with greater interception losses and transpiration from trees. Soil water isotopes showed distinct seasonality in response to precipitation inputs, mixing with resident soil water and the effects of evaporative fractionation. Effects of fractionation were most marked under individual trees and grasslands, where the effects of evaporation on the isotopic composition of percolating water from the upper 0.1 m of the soil was also most pronounced. Isotope dynamics showed that under all land covers, the upper soils had rapid water turnover and were dominated by younger water (<2 months old). At depths of 0.4 m, more damping was evident with water being ∼ 6 months old. Isotopes in plant water also show seasonal variations which were more marked in grasses than trees. Mixing models revealed that grass most likely recycled shallow, younger soil water in transpiration, whilst trees were more dependent on deeper, older sub-soil and groundwater sources. These preliminary results highlight the urgent need for a much greater understanding of water movement and cycling in the shallow critical zone of urban green spaces. This is essential to manage future resilience to climate change and understand the trade-offs between partitioning urban water between evapotranspiration and groundwater recharge.
On Jamming Against Wireless Networks

description: In this paper, we study jamming attacks against wireless networks. Specifically, we consider a network of base stations (BS) or access points (AP) and investigate the impact of a fixed number of jammers that are randomly deployed according to a Binomial point process. We shed light on the network performance in terms of a) the outage probability and b) the error probability of a victim receiver in the downlink of this wireless network. We derive analytical expressions for both these metrics and discuss in detail how the jammer network must adapt to the various wireless network parameters in order to effectively attack the victim receivers. For instance, we will show that with only 1 jammer per BS/AP a) the outage probability of the wireless network can be increased from 1% (as seen in the non-jamming case) to 80% and b) when retransmissions are used, the jammers cause the effective network activity factor (and hence the interference among the BSs) to be doubled. Furthermore, we show that the behavior of the jammer network as a function of the BS/AP density is not obvious. In particular, an interesting concave-type behavior is seen which indicates that the number of jammers required to attack the wireless network must scale with the BS density only until a certain value beyond which it decreases. In the context of error probability of the victim receiver, we study whether or not some recent results related to jamming in the point-to-point link scenario can be extended to the case of jamming against wireless networks. Numerical results are presented to validate the theoretical inferences presented.
