Geometric entanglement of one-dimensional systems: bounds and scalings in the thermodynamic limit

description: In this paper the geometric entanglement (GE) of systems in one spatial dimension (1D) and in the thermodynamic limit is analyzed focusing on two aspects. First, we reexamine the calculation of the GE for translation-invariant matrix product states (MPSs) in the limit of infinite system size. We obtain a lower bound to the GE which collapses to an equality under certain sufficient conditions that are fulfilled by many physical systems, such as those having unbroken space (P) or space-time (PT) inversion symmetry. Our analysis justifies the validity of several derivations carried out in previous works. Second, we derive scaling laws for the GE per site of infinite-size 1D systems with correlation length $ξ\gg 1$. In the case of MPSs, we combine this with the theory of finite-entanglement scaling, allowing to understand the scaling of the GE per site with the MPS bond dimension at conformally invariant quantum critical points.

description: A provision of the Affordable Care Act (ACA) requires states to continue to provide health insurance to young people who have aged out of the foster care system until their 26 th birthday. Although the intent of the provision is to mirror the extended coverage available to young adults whose parents have private health insurance, varying interpretations of the provision by states have effectively blocked these youth formerly in foster care from accessing their federally mandated coverage. An estimated 180,000 young people who have aged out of the foster care system are eligible for extended health care coverage. However, only 13 states have made Medicaid coverage available to all former foster youth who reside in their state, regardless of the state in which they aged out. The policy brief provides an overview of the health needs of young people in and aging out of foster care; describes the coverage to be provided to former foster youth via the ACA, the restrictions that have been applied, and the major reason for opposition to coverage; and makes recommendations to legislators and states for removing barriers to access. The brief also highlights the need to ensure that young people have the knowledge and skills to use their health care coverage.

description: We study the reliability of mass estimates obtained for molecular cloud cores using sub-millimetre and infrared dust emission. We use magnetohydrodynamic simulations and radiative transfer to produce synthetic observations with spatial resolution and noise levels typical of Herschel surveys. We estimate dust colour temperatures using different pairs of intensities, calculate column densities and compare the estimated masses with the true values. We compare these results to the case when all five Herschel wavelengths are available. We investigate the effects of spatial variations of dust properties and the influence of embedded heating sources. Wrong assumptions of dust opacity and its spectral index beta can cause significant systematic errors in mass estimates. These are mainly multiplicative and leave the slope of the mass spectrum intact, unless cores with very high optical depth are included. Temperature variations bias colour temperature estimates and, in quiescent cores with optical depths higher than for normal stable cores, masses can be underestimated by up to one order of magnitude. When heated by internal radiation sources the observations recover the true mass spectra. The shape, although not the position, of the mass spectrum is reliable against observational errors and biases introduced in the analysis. This changes only if the cores have optical depths much higher than expected for basic hydrostatic equilibrium conditions. Observations underestimate the value of beta whenever there are temperature variations along the line of sight. A bias can also be observed when the true beta varies with wavelength. Internal heating sources produce an inverse correlation between colour temperature and beta that may be difficult to separate from any intrinsic beta(T) relation of the dust grains. This suggests caution when interpreting the observed mass spectra and the spectral indices.

Map and Track: State Initiatives to Encourage Responsible Fatherhood, 1999 Edition

description: “What makes an absent, uninvolved father change his behavior and take on his paternal responsibilities—physically, emotionally, and financially?” This question, asked by David Cohen in the introduction to this report, is a complex one. His analysis, drawing on social science “tipping point theory,” which is used to explain the spread of epidemics as well as social ideas, suggests that peer pressure, religious leaders, community programs, and corporate culture all play a role. So, too, do larger social norms. And so, too, do state policies and practices. Through them, states have the opportunity to help define social expectations about fatherhood and develop policies and strategies that can benefit not just fathers, but most importantly, their children. Recognizing this, in 1997, the National Center for Children in Poverty, with funding from the Annie E. Casey Foundation, produced Map and Track: State Initiatives to Encourage Responsible Fatherhood. At that time, every state, the District of Columbia, and Puerto Rico had at least one policy or program initiative to promote and encourage responsible fatherhood. It is now two years later. Evidence from the larger society suggests that there is a cultural change in the way fathers are viewed and view themselves. The people expressing the new view vary widely, from rappers who sing about the joys and responsibilities of fatherhood to employees of corporations who admit to struggling to balance work and family life. Given these larger social changes, this edition of Map and Track Fathers explores how the states are responding. The 1999 edition of Map and Track Fathers addresses four questions that are central to developing an understanding of state strategies to promote responsible fatherhood: • To what extent are state policies and practices responsive to the complex demographic picture of fatherhood that is emerging? • What specific strategies are states developing to promote responsible fatherhood, and how do these strategies vary from state to state and from those used two years ago? • To what extent are states providing leadership in developing policies and practices that promote responsible fatherhood, from an economic, social, and psychological perspective? • What are the lessons from the current status of state efforts to promote responsible fatherhood for future state efforts?
The magnetocaloric and barocaloric effects in Gd5Si2Ge2 compound

Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: The caloric effect in Gd5Si2Ge2 compound is studied experimentally and theoretically. The first-order phase transition is sensitive to both magnetic field and pressure. It indicates that the influences of magnetic field and pressure on the phase transition are virtually equivalent. Moreover, the theoretical analyses reveal that the total entropy change is almost definite at a certain Curie temperature whether the applied external field is magnetic field or pressure. On the basis of theoretical analyses, the entropy change simultaneously induced by magnetic field and hydrostatic pressure can be obtained experimentally. As for Gd5Si2Ge2 compound, the entropy change curve is broadened dramatically, and the refrigerant capacity is improved from 284.7 to 447.0 J/kg. Additionally, the required magnetic field in magnetic refrigeration technique may be reduced by the application of hydrostatic pressure.

description: Across the U.S., large numbers of young children are affected by one or more risk factors that have been linked to academic failure and poor health. Chief among them is family economic hardship, which is consistently associated with negative outcomes in these two domains. As early as 24 months, children in low-income families have been found to show lags in cognitive and behavioral development compared to their peers in higher-income families (see box for definitions of economic hardship). Other risk factors, such as living in a single-parent family or low parent education levels, especially when combined with poverty, can markedly increase children’s chances of adverse outcomes. Children affected by multiple risks – three or more risk factors – are the most likely to experience school failure and other negative outcomes, including maladaptive behavior. This fact sheet highlights important findings about the prevalence of children experiencing risk factors in the U.S. These findings were produced with the Young Child Risk Calculator, a tool of the National Center for Children in Poverty (see box). The national and state prevalence data presented here, along with additional results available from NCCP’s Young Child Risk Calculator, highlight groups of vulnerable children and families whose needs can be addressed through a wide range of family support, health, and education policies. Information about the size and characteristics of a state’s population of young, at-risk children can inform policy decisions about investments in new or expanded supports that help mitigate risks and improve life outcomes for these children.

We assess the effect that living in a similar structure, without knowing it, has on our perception of the equation of state of Dark Energy. We find that structures of dimensions such that they could cause the Cold Spot on the CMB, affect the perceived equation of state of Dark Energy possibly up to ten percent.

description: A new approach to Brownian motion of atomic clusters on solid surfaces is developed. The main topic discussed is the dependence of the diffusion coefficient on the fit between the surface static potential and the internal cluster configuration. It is shown this dependence is non-monotonous, which is the essence of the so-called resonant diffusion. Assuming quicker inner motion of the cluster than its translation, adiabatic separation of these variables is possible and a relatively simple expression for the diffusion coefficient is obtained. In this way, the role of cluster vibrations is accounted for, thus leading to a more complex resonance in the cluster surface mobility.

description: We point out that SO(2N_{c}) gauge theory with N_{f} fundamental Dirac fermions does not have a sign problem at finite baryon number chemical potential μ_{B}. One can thus use lattice Monte Carlo simulations to study this theory at finite density. The absence of a sign problem in the SO(2N_{c}) theory is particularly interesting because a wide class of observables in the SO(2N_{c}) theory coincide with observables in QCD in the large N_{c} limit, as we show using the technique of large N_{c} orbifold equivalence. We argue that the orbifold equivalence between the two theories continues to hold at μ_{B} \neq 0 provided one adds appropriate deformation terms to the SO(2N_{c}) theory. This opens up the prospect of learning about QCD at μ_{B} \neq 0 using lattice studies of the SO(2N_{c}) theory.

description: Using our Binary Population And Spectral Synthesis (BPASS) code we explore the effects on star-formation rate indicators of stochastically sampling the stellar initial mass function, adding a cluster mass dependent stellar upper-mass limit and including binary stars. We create synthetic spectra of young clusters and star-forming galaxies and compare these to observations of H(alpha) emission from isolated clusters and the relation between H(alpha) and FUV emission from nearby galaxies. We find that observations of clusters tend to favour a purely stochastic sampling of the initial mass function for clusters less than 100M(Sun), rather than the maximum stellar mass being dependant on the total cluster mass. It is more difficult to determine whether the same is true for more massive clusters. We also find that binary stars blur some of the observational differences that occur when a cluster-mass dependent stellar upper-mass limit is imposed when filling the IMF. The effect is greatest when modelling the observed H(alpha) and FUV star-formation rate ratios in galaxies. This is because mass transfer and merging of stars owing to binary evolution creates more massive stars and stars that have greater mass than the initial maximum imposed on the stellar population.

description: It has long been argued that the minimal model to describe the low-energy physics of the high-Tc superconducting cuprates must include copper states of other symmetries besides the canonical x2-y2 one, in particular the z2 orbital. Experimental and theoretical estimates of the energy splitting of these states vary widely. With a novel ab initio quantum chemical computational scheme we determine these energies for a range of copper-oxides and -oxyclorides, determine trends with the apical Cu-ligand distances and find excellent agreement with recent Resonant Inelastic X-ray Scattering measurements, available for La2CuO4, Sr2CuO2Cl2, and CaCuO2.

As a joint center of Columbia Law School and the Earth Institute, we focus on international investment and its impacts on sustainable development. In this context, we are increasingly concerned about the repression and criminalization of human rights defenders in the context of investment projects—a situation that unfortunately seems to show no sign of abating.

Our input focuses on one specific topic that we believe may be overlooked in general discussions about human rights defenders: the possibility that the international investment law regime, comprised of thousands of bilateral and multilateral treaties, may actually exacerbate the potential for repression and criminalization of human rights defenders. This concern was raised at a one-day roundtable hosted by CCSI and the Working Group in October 2017, 1 and we believe it merits further exploration.

description: An accurate and easily extendable method to deal with lattice dynamics of solids is offered. It is based on first-principles molecular dynamics simulations and provides a consistent way to extract the best possible harmonic - or higher order - potential energy surface at finite temperatures. It is designed to work even for strongly anharmonic systems where the traditional quasiharmonic approximation fails. The accuracy and convergence of the method are controlled in a straightforward way. Excellent agreement of the calculated phonon dispersion relations at finite temperature with experimental results for bcc Li and bcc Zr is demonstrated.

description: It is well established that phenomenological two-zone diffusion models of the galactic halo can very well reproduce cosmic-ray nuclear data and the observed antiproton flux. Here, we consider lepton propagation in such models and compute the expected galactic population of electrons, as well as the diffuse synchrotron emission that results from their interaction with galactic magnetic fields. We find models in agreement not only with cosmic ray data but also with radio surveys at essentially all frequencies. Requiring such a globally consistent description strongly disfavors very large ($L\gtrsim 15$ kpc) and, even stronger, small ($L\lesssim 1$ kpc) effective diffusive halo sizes. This has profound implications for, e.g., indirect dark matter searches.

While human rights are critical to ensuring sustainable international investment, we have observed that the human rights framework is often ignored or misunderstood in the context of investment. We thus strongly support the Committee’s work in this area, and believe that the General Comment will play an important role in clarifying States’ obligations under the Covenant as they relate to investment regimes and projects.

Our submission focuses on the draft Comment’s discussion of: (1) host and home states’ obligations as they relate to international investment agreements (IIAs), (2) extraterritorial obligations in the context of outward investment, and (3) obligations related to corruption issues.

description: The efficiency of photodesorption of Rb atoms previously collected on polymer organic film has been studied in detail. This study was carried out in a Pyrex glass cell of which the inner surface was covered with (poly)dimethylsiloxane (PDMS) film and illuminated by a powerful flash lamp. The desorption dynamic of the Rb atoms density in the cell caused by the illumination and percentage of desorbed atoms was studied by using of Rb resonance lamp and free running diode laser as sources of probing light. It was determined that 85 percent collected chemical active Rb atoms and stored during 16 seconds in the closed cell, 75 percent in the pumped cell can be desorbed by single flash of the lamp. The number of stored atoms decays with a characteristic time of 60 min in isolated cell and with a time 12.4 minutes in a pumped cell. We believe that this efficient method of collection and fast realization of atoms or molecules could be used for enhancement of sensitivity of existed sensors for the trace detection of various elements (including toxic or radioactive ones) which is important to environmental applications, medicine or in geology. The effect might help to construct an efficient light-driven atomic source for a magneto-optical trap in a case of extremely low vapor density or very weak flux of atoms, such as artificial radioactive alkali atoms.

description: Increased investment in large-scale agricultural, forestry, and fishing projects has raised concerns about pressures on lands and natural resources, and the negative impacts these investments can have when poorly regulated and irresponsibly operated. New disputes between investors and states concerning these investments have sparked commentary regarding the potentially chilling effects they may have on effective regulation of inward investment. At the same time, public and private investments in agriculture are identified as global priorities in the sustainable Development goals. Policy-makers are therefore seeking to facilitate investments in agriculture to advance food security, nutrition, equality, climate and other sustainable development objectives.
The separation of copper sulfide ore minerals from gangue using magnetic nanoparticles functionalized with peptides selected via phage display : a proof of concept
Creators: name: Greene, Robert Crandall
Publisher: name: University of British Columbia
Year: 2020

description: Copper is one of the most important mineral resources. While much unmined copper remains to meet increasing demands, reserve deposit concentrations are dropping while increasing in mineralogical complexity. Porphyry deposits containing the largest reserves have an average grade of 0.25% and often contain elevated concentrations of arsenic in comparison to the deposits that supplied most copper before the 20th century. The current copper porphyry processing scheme first concentrates sulfide ores via froth flotation, then smelts these concentrates. These processes are energy intensive and employ toxic chemical reagents. Low grade deposits must be extensively milled to release ore from gangue. Copper sulfide grains milled to <30 μm in diameter are hard to recover by flotation and an average of 15% of this size fraction is lost to tailings, where it is oxidized, creating acid rock drainage. Copper concentrates containing arsenic at concentrations >2000 ppm cannot be smelted without releasing gaseous arsenic compounds. Common flotation reagents cannot distinguish between arsenic-bearing enargite (Cu₃AsS₄) and chalcopyrite (CuFeS₂). Biotechnology, however, offers a solution to these problems with peptides. Peptides displayed on bacteriophage can be selected for their binding affinity to a specific mineral phase. In this thesis, peptides that bind to chalcopyrite and not to silicate gangue were attached to iron oxide nanoparticles coated with aminopropyl silane via a polyethylene glycol cross-linker. Attachment of the peptides to the nanoparticles was confirmed with FTIR and UV-vis spectroscopy. The nanoparticles were then used to coat and magnetically concentrate chalcopyrite. The nanoparticles preferentially concentrated <38 μm chalcopyrite grains with recoveries near 50%, making them ideally suited to recover the mineral fraction most difficult to float. They were also shown to preferentially coat chalcopyrite over quartz. Concentrates containing 37% chalcopyrite and 13% quartz were collected. Chalcopyrite was concentrated in pure water at pH 7 using non-toxic reagents. Attempts to separate <38 μm enargite and chalcopyrite were met with limited success, though 42% of total copper was recovered from residue otherwise bound for tailings. While this work is still preliminary, these positive results indicate peptide collectors hold great promise. Plans to further explore the potential of peptides are also discussed.

description: Members of the Millennial and iGeneration generations report higher levels of anxiety and depression, lower levels of self-esteem and happiness, lower levels of intrinsic motivation for school, and have less experience with independence, self-directed learning, and decision-making than past generations, and as a result require more guidance to be able to succeed in higher education (Twenge, 2018). These students and early-career professionals may benefit from explicit support around building self-care into academic experiences.

This one-page showcase item asks educational developers and instructors to consider ways to build self-care strategies into their courses, to bolster both students and instructors, and shares sample strategies; these strategies can apply to different types of courses and across disciplines. As part of the showcase, the presenters will invite participant interaction to share ideas, discuss challenges, and ask questions.

description: The energy per particle, symmetry energy, pressure, Free energy are calculated for asymmetric nuclear matter using BHF approach and modern nucleon-nucleon CD-Bonn, Nijm1, Argonnev18 and Reid93 potentials. To obtain saturation in nuclear matter we add three-body interaction terms which are equivalent a la Skyrme to a density-dependent two-nucleon interaction. Good agreement is obtained in comparison with previous theoretical estimates and experimental data.

description: We study theoretically the simultaneous influence of spin accumulation potential $eV_\uparrow-eV_\downarrow$ and the Zeeman exchange field on singlet superconductivity. It is shown that the pair-breaking effect of the Zeeman field can be fully compensated by creation of the appropriate spin accumulation potential in the superconductor. Moreover, superconductivity can be recovered for exchange fields well exceeding the Pauli limiting field. It is proposed that the effect can be experimentally realized on the basis of voltage biased junction consisting of a thin superconducting film sandwiched between two half metals.

Documentation And Examination Of Historic Building Materials For The Purpose Of Conservation:case Study,part Of The Walls At The Citadel Of Ankara (M.Sc.Thesis METU Archaeometry)

description: The study aimed to identify deterioration problems, repair and conservation needs of andesites on the walls of the Ankara Castle. Decay forms of walls were documented by visual examination. Samples taken from the surface of the weathered andesites were examined for their basic physical, mechanical compositional and minerological properties. The bulk density and total porosity were determined as basic physical properties. The mechanical properties were expressed as ultrasonic velocity and modulus of elasticity (Emod). Compositional and mineralogical properties were determined by optical microscopy and XRD analyses. Soluble salt content of the andesite samples was determined by spot tests of anions and electrical conductivity measurements. Findings were evaluated in terms of the long-term weathering behaviour of andesites under the effect of the prevailing climate, air pollution problems of Ankara, dampness problems of the structure, previous repairs with incompatible cement mortars. The surfaces of Ankara Castle andesite blocks were heavily weathered. The results were compared with the physical and mechanical properties of fresh andesites from Gölbaşı- Ankara quarry. The surface of the andesite blocks at the Ankara Castle, had low bulk density and high porosity, low ultrasonic velocity and low Emod values. Thin section and XRD analyses supported those results by revealing the presence of physical and chemical weathering on feldspars and other main minerals of andesite, as well as the presence of amorphous minerals at the surface. Bu çalışmanın amacı Ankara andezitlerinin bozulma sorunlarını, bozulmuşluk durumlarını ortaya koymak, koruma çalışmalarının kapsamını belirlemektir. Çalışmada önce, örneklerin alındığı kale duvarlarında ve andezit taşlarında görülen bozulma türleri belirlenmiştir. Andezit taşlarının yüzeylerinden alınan örneklerin temel fiziksel özellikleri kapsamında birim hacim ağırlığı ve gözenekliliği, mekanik özellikleri kapsamında ise ultrasonik hız değerleri ve esneklik modülü (Emod) hesaplanmıştır. Çalışılan andezit örneklerin mineral bileşimleri ince kesitlerinin optik mikroskop ile incelenmesi ve XRD analizleri ile belirlenmeye çalışılmıştır.Örneklerin içerdiği çözünen tuzların miktarı elektriksel iletkenlik ölçümüyle ve tuzlara ait anyonların türü spot testleriyle belirlenmiştir.
On the rheology of a liquid-vapor interface

description: The mass and momentum balances are theoretically studied in heterogeneous two-component systems. Following Gibbs the system is presented as two bulk and a single surface phases. Comparing the equations derived with some typical rheological models, useful information about the location of the interface is obtained. It was demonstrated that the surface phase for insoluble surfactants coincides with the equimolecular interface, while for soluble ones it is placed on the surface of total mass density zero excess. In both cases the surface phase is close to the surface of tension and kinematic surface.

description: Youth experiencing homelessness suffer both short-term and long- term negative effects: the rate of mental health problems in the United States (U.S.) seems to be higher for youth experiencing homelessness than for the general population (Baggerly, 2004), and twenty percent of adults experiencing homelessness were homeless as children (National Coalition for the Homeless, 1999). Child-centered play therapy (CCPT) has been shown to offer positive short-term effects on self-esteem, developmental delays, and other socio-emotional delays of U.S. youth (Leblanc & Ritchie, 2001). While CCPT shows promise, the benefits of CCPT for youth experiencing homelessness are underexplored. It is imperative that social workers study the potential longitudinal benefits of CCPT specifically for youth experiencing homelessness so that they can continue to provide the most effective therapies to their clients in the short and long terms.

description: Studies have consistently found high prevalence rates of veterans who experience difficulties reintegrating into civilian life, ranging between 50-61%. This paper assesses the current limitations of America’s reintegration methods for military veterans. Commonly identified issues include difficulty finding employment, challenges with readjusting to daily life with family members, and stigma associated with seeking mental health services in military culture. This paper explores three proposals for how social workers can address these limitations in a way that would significantly improve veterans’ reintegration processes. The first proposal aims to improve employment rates by creating a market economy exclusively for retiring service members. The second proposal aims to improve service members’ ability to reintegrate with their family members by placing a stronger emphasis on this domain in the Transition Assistance Program, a mandatory program that all retiring service members must undergo before being discharged. The third proposal aims to increase veterans’ use of mental health services by promoting the use of these services as early on as boot camp. By implementing these proposals, the United States could significantly reduce the prevalence rate of veterans who have difficulty reintegrating.

description: In my essay I will focus on an early case of Transnational Hispanism: the figure of the Spanish writer Vicente Blasco-Ibáñez, who traveled by Argentina, wrote a novel with Argentine characters (The Four Horsemen of Apocalypse, 1916) and was internationally acclaimed for a movie based on his novel (1921). The movie was shot in Los Angeles where “Blascomania” begun. Rodolfo Valentino, in gaucho dress, danced the tango and started “tango fever”. I understand Los Angeles –Hollywood in particular- as a crucial scene where different Hispanic traditions converge. The city and the movie industry create the conditions for the transnational version of Hispanic and Latin identity.
