A spatial analysis of the impacts of climate change on coastal archeological sites in Maryland
Creators: name: Chadwick-Moore, Jennifer L.
Publisher: name: Maryland Shared Open Access Repository
Year: 2014

description: Maryland is currently losing valuable archeological resources at an alarming rate. Members of the archeology community, both local and national, need to be aware of the immediate need for action against the already-active threat of climate change to our history and culture. Archeological resources are at risk from factors including sea-level rise, erosion, and storm surge. A vulnerability assessment was completed to prioritize high-risk archeological sites for management, protection and documentation purposes. Spatial analysis tools were used to develop a GIS model to overlay statewide datasets, including erosion rates, shoreline, inundation and proximity to shoreline data, with archeological resources to assess future impacts. With over 3,100 miles of shoreline in Maryland and relative sea-level rise projections for the Chesapeake Bay region as high as one meter by the year 2100, the findings revealed that thirty-three percent of recorded archeological sites in the project area are at high risk from climate change.

A mixed-methods study on employment within a feminist non-profit organization
Creators: name: Locher, Kelley A.
Publisher: name: Maryland Shared Open Access Repository
Year: 2014

description: This thesis explores the mechanisms that drive individuals employed in non-profit feminist organizations to be proponents of social change. The means to recruit additional support for women's rights is clarified by examining individual and group motivations. Quantitative and qualitative data was collected from 60 individuals currently employed in a feminist nonprofit organization. The findings provide insight into reasons why men and women actively engage in women's advocacy roles. The outcomes suggest there are two consistent characteristics that identify support of feminism: a liberal political orientation and a high educational attainment. In addition, emphasizing female kinship relationships may have a positive effect on male support of feminism. Further, reframing women's rights as a human rights issue may attract and recruit a broader community of individuals.

description: Conductive bridge random access memory devices such as Cu/SiO2/W are promising candidates for applications in neuromorphic computing due to their fast, low-voltage switching, multiple-conductance states, scalability, low off-current, and full compatibility with advanced Si CMOS technologies. The conductance states, which can be quantized, originate from the formation of a Cu filament in the SiO2 electrolyte due to cation-migration-based electrochemical processes. A major challenge related to the filamentary nature is the strong variability of the voltage required to switch the device to its conducting state. Here, based on a statistical analysis of more than hundred fifty Cu/SiO2/W devices, we point to the key role of the activation energy distribution for copper ion diffusion in the amorphous SiO2. The cycle-to-cycle variability is modeled well when considering the theoretical energy landscape for Cu diffusion paths to grow the filament. Perspectives of this work point to developing strategies to narrow the distribution of activation energies in amorphous SiO2.

Statistical mechanics of non equilibrium matter: from minimal models to morphogen gradients
Creators: name: Cocconi, Luca
Publisher: name: Imperial College London
Year: 2022

description: Living systems are by definition far from thermodynamic equilibrium, a condition that can be maintained only at the cost of a continuous injection of energy at the microscale, e.g. via cellular metabolic processes, and dissipation into the surrounding environment. The absence of thermodynamic equilibrium, formalised in the breaking of the global detailed balance condition, allows for a wealth of exotic and often counterintuitive phenomena. Our understanding of the capabilities and limitations of living matter has been greatly informed by thermodynamic approaches, which have to be generalised with respect to their traditional counterparts in order to deal with systems subject to strong random fluctuations. The resulting toolkit of stochastic thermodynamics, in particular the concept of entropy production, gives us a quantitative handle on the degree of "non-equilibriumness" of such stochastic processes. Recently, stochastic thermodynamics has benefitted from cross-contamination with the field-theoretic literature and the techniques developed in the latter for the study of collective behaviour have opened the doors to the thermodynamic characterisation of increasingly complex systems. Starting from minimal mathematical models of single active particles and moving up across scales to the level of morphogenetic processes in real organisms (in particular, the formation of morphogen gradients), this thesis contributes to laying the foundations for a bridge between physical understanding and biological insight. While the focus is here on generic mechanisms and on the development of theoretical tools, the applicability to specific experimental scenarios will be pointed out where relevant.
Thermal decoherence of long-distance entanglement in spin-1 chains

Subjects: subject: Quantum Physics (quant-ph)

description: he thermal entanglement is generated by weakly interacting atoms with an isotropic spin-1 chain. The decoherence of the entanglement is mainly investigated. The effective Hamiltonian is analytically obtained by the approximation method of perturbation. The scaling behavior of the effective coupling is numerically illustrated by the exact diagonalization. It is found out that the decay of the entanglement is slow in the case of non interacting spins. The long-distance thermal entangled states can be used as the noisy channel for the achievement of the quantum teleportation.

description: Background: Cam morphology, a distinct bony morphology of the hip, is prevalent in many athletes, and a risk factor for hip-related pain and osteoarthritis. Secondary cam morphology, due to existing or previous hip disease (eg, Legg-Calve-Perthes disease), is well-described. Cam morphology not clearly associated with a disease is a challenging concept for clinicians, scientists and patients. We propose this morphology, which likely develops during skeletal maturation as a physiological response to load, should be referred to as primary cam morphology. The aim of this study was to introduce and clarify the concept of primary cam morphology.Design: We conducted a concept analysis of primary cam morphology using articles that reported risk factors associated with primary cam morphology; we excluded articles on secondary cam morphology. The concept analysis method is a rigorous eight-step process designed to clarify complex ‘concepts’; the end product is a precise definition that supports the theoretical basis of the chosen concept.Results: We propose five defining attributes of primary cam morphology—tissue type, size, site, shape and ownership—in a new conceptual and operational definition. Primary cam morphology is a cartilage or bony prominence (bump) of varying size at the femoral head-neck junction, which changes the shape of the femoral head from spherical to aspherical. It often occurs in asymptomatic male athletes in both hips. The cartilage or bone alpha angle (calculated from radiographs, CT or MRI) is the most common method to measure cam morphology. We found inconsistent reporting of primary cam morphology taxonomy, terminology, and how the morphology is operationalised.Conclusion: We introduce and clarify primary cam morphology, and propose a new conceptual and operational definition. Several elements of the concept of primary cam morphology remain unclear and contested. Experts need to agree on the new taxonomy, terminology and definition that better reflect the primary cam morphology landscape—a bog-standard bump in most athletic hips, and a possible hip disease burden in a selected few.

description: We present a general model to account for the multimode nature of the quantum electromagnetic field in projective photon-counting measurements. We focus on photon-subtraction experiments, where non-gaussian states are produced conditionally. These are useful states for continuous-variable quantum information processing. We present a general method called mode reduction that reduces the multimode model to an effective two-mode problem. We apply this method to a multimode model describing broadband parametric downconversion, thereby improving the analysis of existing experimental results. The main improvement is that spatial and frequency filters before the photon detector are taken into account explicitly. We find excellent agreement with previously published experimental results, using fewer free parameters than before, and discuss the implications of our analysis for the optimized production of states with negative Wigner functions.

description: Principal Component Analysis (PCA) is an important tool of dimension reduction especially when the dimension (or the number of variables) is very high. Asymptotic studies where the sample size is fixed, and the dimension grows [i.e., High Dimension, Low Sample Size (HDLSS)] are becoming increasingly relevant. We investigate the asymptotic behavior of the Principal Component (PC) directions. HDLSS asymptotics are used to study consistency, strong inconsistency and subspace consistency. We show that if the first few eigenvalues of a population covariance matrix are large enough compared to the others, then the corresponding estimated PC directions are consistent or converge to the appropriate subspace (subspace consistency) and most other PC directions are strongly inconsistent. Broad sets of sufficient conditions for each of these cases are specified and the main theorem gives a catalogue of possible combinations. In preparation for these results, we show that the geometric representation of HDLSS data holds under general conditions, which includes a $ρ$-mixing condition and a broad range of sphericity measures of the covariance matrix.

description: Introduction: MASK-air® is an app whose aim is to reduce the global burden of allergic rhinitis and asthma. A transfer of innovative practices was performed to disseminate and implement MASK-air® in European regions. The aim of the study was to examine the implementation of the MASK-air® app in older adults of the Puglia TWINNING in order to investigate (i) the rate of acceptance in this population, (ii) the reasons for refusal and (iii) the evaluation of the app after its use. Methods: All consecutive geriatric patients aged between 65 and 90 years were included by the outpatient clinic of the Bari Geriatric Immunoallergology Unit. After a 1-h training session, older adults used the app for 6 months. A 6-item questionnaire was developed by our unit to evaluate the impact of the app on the management of the disease and its treatment. Results: Among the 174 recruited patients, 102 accepted to use the app (mean age, SD: 72.4 ± 4.6 years), 6 were lost to follow-up, and 63 had a low education level. The reasons given not to use the app included lack of interest (11%), lack of access to a smartphone or tablet (53%), low computer literacy (28%), and distrust (8%). At follow-up, the overall satisfaction was high (89%), the patient considered MASK-air® “advantageous” (95%), compliance to treatment was improved (81%), and the rate of loss to follow-up had decreased to 6%. Conclusion: Older adults with a low level of education can use the MASK-air® app after a short training session.

description: There is a lack of reliability data within the literature for behavioral tests of auditory processing disorder (APD). Thus, the purpose of this study was to evaluate the test-retest reliability of three tests of temporal processing (Frequency Pattern, Duration Pattern, and Gaps In Noise tests) in normal hearing, young adults. The methods of this study included administering the Frequency Pattern (FP), Duration Pattern (DP) and Gaps In Noise (GIN) tests according to each test's owner's manual to normal hearing adults at one test session and then again seven to nine days later. The data was analyzed using a general linear model analysis of variance (ANOVA) for each test individually in order to compare the mean scores obtained at test session one to the mean scores obtained at test session two. Additionally, Pearson r correlation coefficients were analyzed for each test in order to investigate the reliability of each test. The results of this study indicated that there were no significant differences between the mean scores of any of the tests administered across testing sessions. Additionally, moderate to strong correlation data was found (.446 < r < .71). Thus, this study concludes that the FP, DP, and GIN tests are reliable clinical tools.

The territorial architecture of government

name: Marks, G.

Publisher: name: Blackwell Publishing Ltd
Year: 2021

description: This article sets the stage for a special issue that examines the interplay between subnational and supranational governance. It begins by discussing how the territorial architecture of government has become more multilevel as national governments have shifted authority both downwards to subnational governments and upwards to international and supranational institutions. Next, we argue that this multilevel structure emanates from a tension between the drive to reap the functional benefits of scale diversity in a globalizing economy and the pressures arising from collective self-rule. We build on the research in this special issue to highlight some tangible effects of this tension for policy, politics, and polity. Subnational and supranational governance are conventionally perceived as separate phenomena with distinct consequences, and yet they are intimately connected in a fluid territorial architecture of multilevel governance.

Subjects: subject: Fluid Dynamics (physics.flu-dyn)

description: In the present study, applications of the SPH method to industrial related issues are considered by starting from an existing open source 2D SPH code, namely the SPHYSICS code, which offers an effective ground for numerical developments, which are performed in order to bring an answer to industrial problems, such as simulations of solid/fluid coupling in a free surface flow context. The purpose of the present paper is therefore to expose the numerical developments which yield an enhanced version (referred to as "SPHYSIC2") of the initial code. Firstly, the different features added to obtain the operational code needed for engineering applications are described, and so are the problems raised on this way, offering a kind of review of SPH methods for engineers. Secondly, the validation of the proposed code is partially presented with two well known but difficult test cases, namely the classical "dam break" and "wedge entry" problems. Thirdly, principles of a method to solve solid/solid contacts, frequently present in realistic configuration, are exposed and applied to achieve more complex simulations. Finally, perspectives for new features of the SPHYSIC2 code are exposed and discussed.

description: We study a model of growing planar tree graphs where in each time step we separate the tree into two components by splitting a vertex and then connect the two pieces by inserting a new link between the daughter vertices. This model generalises the preferential attachment model and Ford's $α$-model for phylogenetic trees. We develop a mean field theory for the vertex degree distribution, prove that the mean field theory is exact in some special cases and check that it agrees with numerical simulations in general. We calculate various correlation functions and show that the intrinsic Hausdorff dimension can vary from one to infinity, depending on the parameters of the model.

description: Spatial attention helps us to efficiently localize objects in cluttered environments. However, the processing stage at which spatial attention modulates object location representations remains unclear. Here we investigated this question identifying processing stages in time and space in an EEG and fMRI experiment respectively. As both object location representations and attentional effects have been shown to depend on the background on which objects appear, we included object background as an experimental factor. During the experiments, human participants viewed images of objects appearing in different locations on blank or cluttered backgrounds while either performing a task on fixation or on the periphery to direct their covert spatial attention away or towards the objects. We used multivariate classification to assess object location information. Consistent across the EEG and fMRI experiment, we show that spatial attention modulated location representations during late processing stages (>150 ms, in middle and high ventral visual stream areas) independent of background condition. Our results clarify the processing stage at which attention modulates object location representations in the ventral visual stream and show that attentional modulation is a cognitive process separate from recurrent processes related to the processing of objects on cluttered backgrounds.

description: This collection consists of five contributions presented as plenaries at a conference, ‘Theory Meets Crisis’, held at the Robert Schuman Centre, European University Institute, in July 2016. The organizers of the conference asked leading scholars of varieties of capitalism, democracy, redistributional politics, European integration and political parties to engage the theoretical implications of Europe’s multiplex crisis. To what extent and how, we asked, has the European crisis confirmed, undermined or reshaped theoretically grounded expectations in these fields? Beyond the confirmation or disconfirmation of particular hypotheses, does the crisis impel us to take a fresh look at comparative politics?

description: This article argues that the perforation of national states by immigration, integration and trade may signify a critical juncture in the political development of Europe no less consequential for political parties and party systems than the previous junctures that Lipset and Rokkan detect in their classic article. We present evidence suggesting that (1) party systems are determined in episodic breaks from the past; (2) political parties are programmatically inflexible; and, (3) as a consequence, party system change comes in the form of rising parties.
The Distributed Multi-User Point Function

description:    In this paper, we study the problem of information-theoretic distributed multi-user point function, involving a trusted master node, $N \in \mathbb{N}$ server nodes, and $K\in \mathbb{N}$ users, where each user has access to the contents of a subset of the storages of server nodes. Each user is associated with an independent point function $f_{X_k,Z_k}: \{1,2,\hdots,T\} \rightarrow{GF(q^{m R_k})},T,mR_k \in \mathbb{N}$. Using these point functions, the trusted master node encodes and places functional shares $G_1,G_2,\hdots,G_N \in GF(q^{M}), M \in \mathbb{N}$ in the storage nodes such that each user can correctly recover its point function result from the response transmitted to itself and gains no information about the point functions of any other user, even with knowledge of all responses transmitted from its connected servers. For the first time, we propose a multi-user scheme that satisfies the correctness and information-theoretic privacy constraints, ensuring recovery for all point functions. We also characterize the inner and outer bounds on the capacity---the maximum achievable rate defined as the size of the range of each point function $mR_k$ relative to the storage size of the servers $M$---of the distributed multi-user point function scheme by presenting a novel converse argument.

description: Introduction: This study aimed to use a novel MRI contrast, the standardized T1-weighted/T2-weighted (sT1w/T2w) ratio, to assess damage of the white matter and gray matter in multiple system atrophy (MSA). Furthermore, this study investigated whether the sT1w/T2w ratio was associated with cognitive impairment in MSA. Methods: The white matter and gray matter sT1w/T2w ratio of 37 MSA patients and 19 healthy controls were measured. Correlation analyses were used to evaluate the relationship between sT1w/T2w ratio values and clinical variables, and a multivariate analysis was used to identify independent factors associated with cognitive impairment in MSA. Results: MSA patients showed a higher white matter sT1w/T2w ratio value than controls (p < 0.001), and the white matter sT1w/T2w ratio value was significantly correlated with the International Cooperative Ataxia Rating Scale score (r = 0.377, p = 0.021) and the Addenbrooke's cognitive examination III score (r = -0.438, p = 0.007). Cognitively impaired MSA patients had a significantly higher white matter sT1w/T2w ratio value than cognitively preserved MSA patients (p = 0.010), and the multiple logistic regression analysis revealed that the median white matter sT1w/T2w ratio value was independently associated with cognitive impairment in MSA. Conclusion: The sT1w/T2w ratio is sensitive to degenerative changes in the white matter that is associated with cognitive ability in MSA patients.

description: Prototheca are unicellular, achlorophyllous, yeast-like microalgae that occur in a wide range of natural habitats. At least five species have been implicated as the causative agents of opportunistic infections of men. Human protothecosis typically manifests as cutaneous, articular, or systemic disease. Treatment is largely empirical with poorly predictable and often unsuccessful outcomes. This is largely due to the frequently observed resistance of Prototheca species to conventional antimicrobial agents. This work is the first to perform drug susceptibility profiling exclusively on isolates from human cases of protothecosis. A total of 23 such isolates were tested against amphotericin B and 9 azoles, including efinaconazole and luliconazole, whose activities against Prototheca have never been studied before. Efinaconazole was the most active, with median minimum inhibitory concentration (MIC) and minimum algicidal concentration (MAC) values of 0.031 mg/L and 0.063 mg/L, respectively. Fluconazole and luliconazole had the lowest activity, with median MIC and MAC values of 128 mg/L. To conclude, amphotericin B and most of the azoles showed in vitro activity, with an algicidal rather than algistatic effect, against Prototheca. Still, the activity of individual drugs differed significantly between the species and even between strains of the same species. These differences can be attributed to a species-specific potential for acquiring drug resistance, which, in turn, might be linked to the treatment history of the patient from whom the strain was recovered. The results of this study underscore the potential clinical utility of efinaconazole as a promising therapeutic agent for the treatment of human protothecosis.

description: This paper introduces a new dataset on regional authority in 42 democracies for 1950-2006 and formulates five hypotheses. First, an S-curve effect describing a logistic association between the population of a country and its regional authority. Secondly, a heteroskedasticity effect, in which the variance in regional authority among larger countries is greater than that among smaller countries. Thirdly, an identity effect, in which the allocation of authority to a jurisdiction is influenced by the relative strength of a population's identity to the community encompassed by the jurisdiction. Fourthly, a democracy effect, which leads democracies to have higher levels of regional authority than dictatorships. Fifthly, an integration effect, which removes a potential economic cost on regionalization by providing a transnational frame for economic exchange.
Uptake and depuration rates of bulk ZnO powder, ZnCl2, and ZnO nanoparticles by Eisenia fetida before and after soil weathering: the potential for trophic transfer

description: The earthworm Eisenia fetida was exposed to three treatments of isotopically-labeled zinc (68ZnCl2, bulk 68ZnO, and 68ZnO nanoparticles (NPs) at 148 mg/kg Zn) amended to topsoil for 21 days followed by 21 days in a ?clean? topsoil to assess uptake and elimination rates (Initial). The exposure was repeated following a 21 day soil-aging period (Aged). All Zn treatments followed the same two-compartment elimination pattern. During the Initial experiment, bulk 68ZnO demonstrated slower uptake in compartment one than 68ZnCl2 and 68ZnO NPs, then matched the rates of other treatments during the Aged experiment. A significant difference was observed in compartment two of the 68ZnO NP treatment in both experiments. We saw no evidence of ZnO NP retention in E. fetida to suggest the potential for trophic transfer of ZnO NPs in a terrestrial food web. These data benefit risk assessment as ZnO NP (5-30nm) mimics ZnCl2 in E. fetida.

The grievance field; an empirical study of grievance processes in a plywood factory
Creators: name: Murphy, Brian C.
Publisher: name: University of British Columbia

description: There are three major facets to industrial employer-employee relations: work processes, collective bargaining and grievance processes. The form of the first is established mainly at the initiative of the employer. The second is generally initiated by employee organizations and results in a document called a collective agreement which sets forth agreed upon patterns of interaction between employer and employee. The third, Grievance Processes, are the means whereby individual and group differences of opinion regarding interpretation of abstractions in the collective agreement, formal instructions for work performance, etc. are reconciled. This study seeks to determine the important situational, behavioral and personal variables associated with differences in quantity and quality of grievance output and union political activity within the plant. It examines the way in which these variables interact with one another within a "field" to produce grievance activity of given character and quantity. Personality variables, in particular a tendency towards "aggressive" behavior, appear to be of prime importance in determining which employees will be active in presenting grievances, holding union office, and several other activities. Union office-holders and grievers are found to have higher accident rates, to be dunned more by creditors, to participate more on company athletic teams, etc., than other employees. The communication potential of work positions, and repetitiveness of the work cycle are among the few situational variables found to have a significant influence on the grievance outcome. Seniority, a structural variable, is found to be extremely important in determining which employees will take part in grievance and union political activity. High Status seems to increase the likelihood of employees holding union office as evidenced by the greater political activity of those born in English speaking countries, with more education, and with higher pay. Status appears to have little effect on the propensity of employees to engage in grievance pressing. Age appears to be inversely correlated with the tendency of the individual to take part in union political activity. However, it seems to be unrelated to pressing of grievances. Grievance output in a conventional absentee shareholder owned plywood plant is briefly compared with activity in a "worker owned" plywood plant.

Palladium, platinum, selenium and tellurium enrichment in the Jiguanzui-Taohuazui Cu-Au Deposit, Edong Ore District: Distribution and comparison with Cu-Mo deposits

description: The Jiguanzui-Taohuazui Cu-Au deposit is located in the Edong ore district, Middle–Lower Yangtze River metallogenic belt, eastern China. The deposit is palladium, platinum, selenium and tellurium enriched; however, the distribution of these metals is unclear. Three mineral assemblages of ore in the deposit have been identified, namely: a magnetite-bornite-chalcopyrite-(hematite) assemblage (Mt-Bn-Cp-Hm), a chalcopyrite-pyrite assemblage (Cp-Py), and a pyrite-chalcopyrite-(sphalerite) assemblage (Py-Cp-Sph). Forty-eight bulk ore assay results show high concentrations of up to 66.9 ppb for Pd, 5.9 ppb for Pt, 150 ppm for Se and 249 ppm for Te. The high temperature Mt-Bn-Cp-Hm assemblage (530–380 °C) is enriched in Pt and Pd, whereas the Py-Cp-Sph assemblage in the marble-replacement ore (300–220 °C) hosts the major Se and Te mineralization. Palladium, Pt, and Se are mostly hosted in sulfide minerals, whereas Te is hosted in tellurides and Bi-Te-S sulfosalt minerals. Building on previous experimental and thermodynamic calculations, we propose the major controls on the Pd and Pt distribution in the deposit are temperature and salinity, whereas the Se and Te mineralization is promoted by the precipitation of major sulfide phases such as pyrite, chalcopyrite and sphalerite. A comparison of the ores from the Jiguanzui-Taohuazui Cu-Au and Tongshankou Cu-Mo deposits in the Edong ore district shows that the Cu-Au deposit has higher PGE and Te, but similar Se concentrations. This scenario is consistent with the average grades and bulk ore contents of these elements from global (oxidized) porphyry (±skarn) Cu deposits. This suggests that the saturation of magmatic sulfides in the magma chamber as a result of higher proportion of crustal S-rich and/or reduced material contamination can be detrimental for PGE and Te enrichment processes, and thus, Cu-Au porphyry (±skarn) deposits have more potential for higher Pd and Te concentrations than the Cu-Mo deposits.

description: Justice evaluations are proposed to provide a link between the objective level of inequality and the consequences at the individual and societal level. Available instruments, however, focus on the subjective perception of inequality and income distributions. In light of findings that subjective perceptions of inequality and income levels can be biased and subject to method effects, we present the newly developed Justice Evaluation of the Income Distribution (JEID) Scale, which captures justice evaluations of the actual earnings distribution. JEID comprises five items that provide respondents with earnings information for five groups at different segments along the distribution of earnings in a given country. We provide a German-language and an English-language version of the scale. The German-language version was developed and validated based on three comprehensive heterogeneous quota samples from Germany; the translated English-language version was validated in one comprehensive heterogeneous quota sample from the UK. Using latent profile analysis and k-means clustering, we identified three typical response patterns, which we labeled “inequality averse,” “bottom-inequality averse,” and “status quo justification.” JEID was found to be related to normative orientations in the sense that egalitarian views were associated with stronger injustice evaluations at the bottom and top ends of the earnings distribution. With a completion time of between 1.50 and 2.75 min, the JEID scale can be applied in any self-report survey in the social sciences to investigate the distribution, precursors, and consequences of individuals’ subjective evaluations of objective differences in earnings.

description: We study superfluid to Anderson insulator transition of strongly repulsive Bose gas in a one dimensional incommensurate optical lattice. In the hard core limit, the Bose-Fermi mapping allows us to deal with the system exactly by using the exact numerical method. Based on the Aubry-André model, we exploit the phase transition of the hard core boson system from superfluid phase with all the single particle states being extended to the Bose glass phase with all the single particle states being Anderson localized as the strength of the incommensurate potential increasing relative to the amplitude of hopping. We evaluate the superfluid fraction, the one particle density matrices, momentum distributions, the natural orbitals and their occupations. All of these quantities show that there exists a phase transition from superfluid to insulator in the system.

description: This article argues that the chief challenge to international governance is an emerging political cleavage, which pits nationalists against immigration, free trade, and international authority. While those on the radical left contest international governance for its limits, nationalists reject it in principle. A wide-ranging cultural and economic reaction has reshaped political conflict in Europe and the United States and is putting into question the legitimacy of the rule of law among states.
