description: Purpose: In older women, breast cancer and its treatment can have profound impact on their physical, mental, and social health, especially in frail patients. This study evaluated the association between frailty and long-term health-related quality of life (HRQOL) in older women undergoing breast cancer treatment. Methods: Using the Carolina Senior Registry (CSR), participants with breast cancer were contacted to complete a follow-up HRQOL questionnaire (median 4 years). Baseline Geriatric Assessment (GA) variables were used to calculate the Carolina Frailty Index (CFI) and categorize participants as robust, pre-frail, or frail. Outcomes included HRQOL domains of physical function, social roles, fatigue, depression, anxiety, pain, and sleep disturbance assessed using PROMIS® instruments. Regression modeling compared outcomes between frailty groups using adjusted mean differences (AMD). Results: Of 190 eligible patients, 63 completed follow-up HRQOL survey. Mean age was 70 years (range 65–86) and 91% were white. Based on the CFI, 49 (78%) patients were robust, 11 (18%) pre-frail, and 3 (5%) frail. After controlling for age and cancer stage, patients identified as pre-frail/frail reported worse physical function (AMD − 9.2, p < 0.001) and social roles (AMD − 7.2, p = 0.002) and more fatigue (AMD 7.6, p = 0.008), depression (AMD 5.6, p = 0.004), and sleep disturbance (AMD 6.9, p = 0.008) compared to robust patients at follow-up. Conclusions: Frailty in older women with breast cancer was associated with worse long-term HRQOL outcomes. Further research is needed to develop interventions for frail patients at-risk for reduced HRQOL.

description: With the “death of god” and the resulting decline of metaphysics, Western thought has become aware of the dissolution of its foundations provoking a receding conviction in universal truth. In this context, hermeneutics can contribute to nihilism, preventing its tragic deviation. Hermeneutics appears as a constructive approach that successfully reacts to the receding conviction in universal truth: it emphasizes the variety and the flexibility of the various interpretations with which everyone approaches the plurality of the world. Every interpretation is a different point of view, which considers itself exclusive and correct, pretending (sometimes violently) to be distinguished from other interpretations. This is the reason why the task of philosophy today is to promote a conscientious reflection upon a pacific coexistence between different cultural and religious experiences.

description: The Fe Kalpha emission line is the most ubiquitous feature in the X-ray spectra of active galactic nuclei (AGN), but the origin of its narrow core remains uncertain. Here, we investigate the connection between the sizes of the Fe core emission regions and the measured sizes of the dusty tori in 13 local Type 1 AGN. The observed Fe K emission radii (R_fe) are determined from spectrally resolved line widths in X-ray grating spectra, and the dust sublimation radii (R_dust) are measured either from optical/near-infrared reverberation time lags or from resolved near-infrared interferometric data. This direct comparison shows, on an object-by-object basis, that the dust sublimation radius forms an outer envelope to the bulk of the Fe K emission. R_fe matches R_dust well in the AGN with the best constrained line widths currently. In a significant fraction of objects without a clear narrow line core, R_fe is similar to, or smaller than the radius of the optical broad line region. These facts place important constraints on the torus geometries for our sample. Extended tori in which the solid angle of fluorescing gas peaks at well beyond the dust sublimation radius can be ruled out. We also test for luminosity scalings of R_fe, finding that Eddington ratio is not a prime driver in determining the line location in our sample. We discuss in detail potential caveats due to data analysis and instrumental limitations, simplistic line modeling, uncertain black hole masses, as well as sample selection, showing that none of these is likely to bias our core result. The calorimeter on board Astro-H will soon vastly increase the parameter space over which line measurements can be made, overcoming many of these limitations.

Nostalgic Freilassen

Publisher: name: Trópos

description: Postmodern hermeneutics strongly opposes itself to Heidegger’s alleged anti–modernism. This opposition is found in the weak thought developed by Vattimo and Caputo, and in this article I will argue that their dismissal of Heidegger’s nostalgia relies on a problematic distinction between Heidegger’s progressive, leftist non–foundationalism and his rightist, nostalgic eschatology. This distinction is problematic for two reasons: Firstly, it overlooks the crucial link between Heidegger’s notion of belonging (Zugehörigkeit) and attunements (Stimmungen) that provides Heidegger’s nostalgia with a hermeneutic importance, and, secondly, it assumes that Heidegger actually wants to return to a time prior to metaphysics, whereby it fails to take into account the late Heidegger’s critique of the metaphysics of the will. These two points I take to be defining for the affectivity central to Heideggerian hermeneutics and, consequently, to be crucial for any hermeneutics with emancipatory ambitions. If weak thought is still embedded in the metaphysics of the will, we must strive to make it even weaker by considering the Heideggerian terms Freilassen and Gelassenheit, which will reveal that nostalgia is not politically dangerous but, rather, emancipatory insofar as it seeks to free a different mode of experience beyond the willful metaphysics of Gestell.

We express our operators in terms of the Hall-Littlewood symmetric functions of the same variables and of the parameter $t$ corresponding to the partitions with one part only. Our expression is based on the notion of Baker-Akhiezer function.

Service Providers (SPs)

description: Journals Outreach is a sub-task of the CESSDA Work Plan 2020 Task Widening Activities and Journals Outreach. The objective of this report is to provide an assessment of CESSDA Service Providers’ (SPs) capacities, policies, and services for responding to the needs of journals with respect to access and medium/long term preservation of data and replication material. To this effect, an online survey targeting the current consortium of 22 CESSDA Members was conducted, with questions guided by the findings of the first deliverable. The survey sought to profile SPs in relation to the requirements expected by journals, to assess potential limitations encountered, to gather information on actual and planned collaboration with journals, to investigate potential support that SPs would benefit from and to gauge their views on CESSDA’s involvement in coordinating such initiatives. The first major finding is that SPs are well placed to offer long-term curated data collections, quality control, personalised expert curation support and links to publications, training on data management planning and promotional material related to data usage. The second major finding is that the SPs are overwhelmingly positive towards offering data sharing and replication services in collaboration with publishers and journals.

description: We demonstrate a combination of computational tools and experimental 4D-STEM methods to image the local magnetic moment in antiferromagnetic Fe$_2$As with 6 angstrom spatial resolution. Our techniques utilize magnetic diffraction peaks, common in antiferromagnetic materials, to create imaging modes that directly visualize the magnetic lattice. Using this approach, we show that center-of-mass analysis can determine the local magnetization component in the plane perpendicular to the path of the electron beam. Moreover, we develop Magnstem, a quantum mechanical electron scattering simulation code, to model electron scattering of an angstrom-scale probe from magnetic materials. Using these tools, we identify optimal experimental conditions for separating weak magnetic signals from the much stronger interactions of an angstrom-scale probe with electrostatic potentials. Our techniques should be useful for characterizing the local magnetic order in systems such in thin films, interfaces, and domain boundaries of antiferromagnetic materials, which are difficult to probe with existing methods.

description: Background: Several foods and nutrients have been linked to the development of prostate cancer, but the association between healthy dietary patterns and prostate cancer aggressiveness is less studied. The aim of this study was to evaluate the relationship between the Mediterranean diet (MED) and Dietary Approaches to Stop Hypertension (DASH) diet scores and prostate cancer aggressiveness by race. Methods: Data from the population-based, case-only North Carolina–Louisiana Prostate Cancer Project (PCaP) were used to examine the association between diet quality, measured by MED and DASH scores, and prostate cancer aggressiveness in 1899 African American (AA) and European American (EA) research subjects. Dietary intake was assessed using a modified National Cancer Institute Diet History Questionnaire. Logistic regression was used to estimate adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for high versus low-intermediate aggressive prostate cancer. Results: Higher MED scores were inversely associated with high aggressive prostate cancer overall (OR: 0.66; 95% CI: 0.46, 0.95 for high versus low scores); results were similar for AA and EA men. A weaker inverse association between DASH scores and prostate cancer aggressiveness was found (OR: 0.76; 95% CI: 0.55, 1.06). Conclusions: Higher diet quality, as represented by a Mediterranean-style diet or DASH diet, may reduce the odds of high aggressive prostate cancer.

description: Weakly interacting K --> pi X^0 emission with m_{X^0} \simeq m_{pi^0} is out of sight of the current K^+ --> pi^+ nu nubar study, but it can be sensed by the K_L --> pi^0 nu nubar search. This evades the usual Grossman-Nir bound of B(K_L --> pi^0 nu nubar) < 1.4 x 10^-9, thus the KOTO experiment is already starting to probe New Physics. An intriguing possibility is the Z' gauge boson of a weak leptonic force that couples to L_mu - L_tau (the difference between the muon and tauon numbers), which may explain the long-standing "muon g-2" anomaly, but is constrained by nu_mu N --> nu_mu N mu^+ mu^- scattering to m_{Z'} \lesssim 400 MeV. An explicit model for K --> pi Z' is given, which illustrates the link between rare kaon and B --> K mu^+ mu^-, K^{(*)} nu nubar decays. Complementary to these searches and future lepton experiments, the LHC might discover the scalar boson phi responsible for light m_{Z'} generation via phi --> Z' Z' --> 2(mu^+ mu^-).

description: The paper discusses the function of the philosophical profession, focusing on the role that hermeneutical thought can play in rethinking the place of philosophy. At first, I sum up the instances of a Marxist, a therapeutic–consolatory and an analytical perspective: philosophy must transform the world; philosophy offers existential treatments; philosophy goes in search of specific objects. Secondly, I show the reason behind the deep and ambiguous relationship between philosophy and other technical–professional sectors of society—from antiquity to the present. After this, I clarify how the concept of truth proposed by contemporary hermeneutical thought enables to connect and renew these three instances, because it allows for rethinking the concept of transformation as well as for understanding the falsifying and subjective dimensions of this concept. Finally, I underline the shocking effect of a philosophical transformation, specifying that the object of this kind of transformation also extends to common sense and the social world. At last, I suggest a moderate apology for hermeneutics based on the conviction that hermeneutics is able to educate to take care of subjects.

description: In this work we assess the role played by the dynamical adaptation of the interactions network, among agents playing Coordination Games, in reaching global coordination and in the equilibrium selection. Specifically, we analyze a coevolution model that couples the changes in agents' actions with the network dynamics, so that while agents play the game, they are able to sever some of their current connections and connect with others. We focus on two update rules: Replicator Dynamics (RD) and Unconditional Imitation (UI). We investigate a Pure Coordination Game (PCG), in which choices are equivalent, and on a General Coordination Game (GCG), for which there is a risk-dominant action and a payoff-dominant one. The network plasticity is measured by the probability to rewire links. Changing this plasticity parameter, there is a transition from a regime in which the system fully coordinates in a single connected component to a regime in which the system fragments in two connected components, each one coordinated on a different action (either if both actions are equivalent or not). The nature of this fragmentation transition is different for different update rules. Second, we find that both for RD and UI in a GCG, there is a regime of intermediate values of plasticity, before the fragmentation transition, for which the system is able to fully coordinate in a single component network on the payoff-dominant action, i. e., coevolution enhances payoff-dominant equilibrium selection for both update rules.

description: The paper examines the phenomenon of emancipation, not in terms of changes in personal status and rights, not in terms of changes in social structures and structures of power, but in terms of the anthropological metaphysics found at the core of the emancipatory effort. Having first traced this matter in the history of the concept of emancipation and secondly explored it phenomenologically in the Tunisian Revolution, the paper concludes by pointing to a fundamental difference between the traditional notions of emancipation and its recent manifestation in Tunisia; a difference, namely, between the human being as possessing and producing, on the one hand, and, on the other hand, as a primarily responsive being. This being–responsive at the same time sheds new light on the concept of freedom and how the experience of freedom and of being human guides the project of emancipation.

description: What does “emancipation” mean today? A hermeneutical approach to this question tries above all to investigate the significance of emancipation in relation to human praxis. Since capitalist societies today prompt the rethinking of emancipatory practices, this volume sets the task to examine the topic of emancipation through a dialogue between different hermeneutical and aesthetical inquiries, while also opening for broader philosophical discussions of the main question here: “what does it mean for us to emancipate ourselves today?”. Taking the lead from central hermeneutical concepts such as plurality, praxis, non–foundational rationality, history, and the Other, the contributions engage with many different philosophical disciplines as well as philosophical currents.

title: The mechanism of site-specific recombination encoded by TN3
Creators: name: Dyson, Paul J.
Publisher: name: University of Glasgow
Year: 1984

description: The bacterial ampicillin resistance transposon Tn3 encodes a site-specific recombination system which mediates the second step in its transposition pathway: the resolution of cointegrates (Arthur and Sherratt (1979) Mol.gen.Genet. 175, 267-274). It vitro analysis has shown that this recombination system is simple: dependent on the transposon encoded resolvase protein acting at res, a site required in cis(Reed (1981) Cell 25, 713-719). Resolvase binds at res at three sites (Grindley et al (1982) Cell 30, 713-719). res was defined to a region of 139bp by in vivo analysis, which confirms that the extent of DNA bound by resolvase in vitro constitutes res. Truncated res regions have been analysed for resolvase binding and function. The results confirm the importance of a sequence determinant for resolvase binding, suggest non-cooperative binding at each of the three sites, but cooperativity for binding at both half-sites of the individual binding sites. In terms of function a truncated res region was shown to have secondary site, activity in that it could recombine with res-wt but not efficiently with itself. The difference in primary and secondary res sites is the presence of resolvase binding site III in the former. This binding site can be reintroduced at a different position to a truncated res to partially reconstitute primary site activity. The normal cointegrate substrate contains directly repeated copies of res. Inversion substrates, containing two inverted res regions, were analysed for recombination. Inversion is approximately 50 times less efficient than resolution. This rate is comparable to that of resolution of a substrate containing directly repeated secondary res-regions. These results, taken in context with evidence from other workers on both Tn3 encoded site-specific recombination and bacteriophage lambda site-specific recombination, suggest that the mechanism by which two res regions are brought together prior to recombination is determined by the higher-order structure formed by resolvase and res.

description: Magnetic excitations in layered magnetic materials that can be thinned down the two-dimensional (2D) monolayer limit are of high interest from a fundamental point of view and for applications perspectives. Raman scattering has played a crucial role in exploring the properties of magnetic layered materials and, even-though it is essentially a probe of lattice vibrations, it can reflect magnetic ordering in solids through the spin-phonon interaction or through the observation of magnon excitations. In bulk CrSBr, a layered A type antiferromagnet (AF), we show that the magnetic ordering can be directly observed in the temperature dependence of the Raman scattering response i) through the variations of the scattered intensities, ii) through the activation of new phonon lines reflecting the change of symmetry with the appearance of the additional magnetic periodicity, and iii) through the observation, below the Neel temperature (TN) of second order Raman scattering processes. We additionally show that the three different magnetic phases encountered in CrSBr, including the recently identified low temperature phase, have a particular Raman scattering signature. This work demonstrates that magnetic ordering can be observed directly in the Raman scattering response of bulk CrSBr with in-plane magnetization, and that it can provide a unique insight into the magnetic phases encountered in magnetic layered materials.

description: The article is based on a sentence composed by Noam Chomsky: “Colorless green ideas sleep furiously”. Although a phenomenon referring to a grammatically correct, but logically contradictory phrase is not found in the empirical field, it can stimulate a certain perspective of experience in the field of imagination. The cultivation of this oxymoronic unity of opposites serves for a better understanding of the latent function of imagination. Based on the insights by Anaximander, Beckett, Stoicism, British Empiricism, Husserl and Sartre, this sentence is reconsidered as an impulse, facilitating the dynamism of the activity and passivity of consciousness as well as turning the logical contradiction into the principle of change orientation.

description: Recently, face recognition systems have demonstrated remarkable performances and thus gained a vital role in our daily life. They already surpass human face verification accountability in many scenarios. However, they lack explanations for their predictions. Compared to human operators, typical face recognition network system generate only binary decisions without further explanation and insights into those decisions. This work focuses on explanations for face recognition systems, vital for developers and operators. First, we introduce a confidence score for those systems based on facial feature distances between two input images and the distribution of distances across a dataset. Secondly, we establish a novel visualization approach to obtain more meaningful predictions from a face recognition system, which maps the distance deviation based on a systematic occlusion of images. The result is blended with the original images and highlights similar and dissimilar facial regions. Lastly, we calculate confidence scores and explanation maps for several state-of-the-art face verification datasets and release the results on a web platform. We optimize the platform for a user-friendly interaction and hope to further improve the understanding of machine learning decisions. The source code is available on GitHub, and the web platform is publicly available at http://explainable-face-verification.ey.r.appspot.com.

description: The article discusses Heidegger’s notion of ‘restraint’ (Verhaltenheit) as a basic disposition (Grundstimmung) in Contributions to Philosophy. Heidegger here uses the ‘passive’ semantics of the word and turns it into an ‘active’ anticipation of the style of philosophy and of the mankind to come, resulting in a strong tension in the description of restraint. Since restraint is said to be “the ground of care”, this tension carries over into Heidegger’s description of Dasein, whose being it is to care, and into the determination of philosophy as the essential activity of Dasein. While restraint characterizes the understanding of philosophy as Heidegger conceives it in terms of the history of being, the disposition of Verhaltenheit also relates to the description of philosophy as ‘considerate thinking’ (Besinnung). Yet while the account of ‘restraint’ aims at a shared disposition of both awaiting and anticipating, Besinnung and Selbstbesinnung in particular describe an individual activity much more in line with Heidegger’s radically individualist account of philosophy in Being and Time.

description: The conductance of graphene nanoribbons and nanoconstrictions under the effect of a scanning gate microscopy tip is systematically studied. Using a scattering approach for noninvasive probes, the first- and second-order conductance corrections caused by the tip potential disturbance are expressed explicitly in terms of the scattering states of the unperturbed structure. Numerical calculations confirm the perturbative results, showing that the second-order term prevails in the conductance plateaus, exhibiting a universal scaling law for armchair graphene strips. For stronger tips, at specific probe potential widths and strengths beyond the perturbative regime, the conductance corrections reveal the appearance of resonances originated from states trapped below the tip. The zero-transverse-energy mode of an armchair metallic strip is shown to be insensitive to the long-range electrostatic potential of the probe. For nanoconstrictions defined on a strip, scanning gate microscopy allows to get insight into the breakdown of conductance quantization. The first-order correction generically dominates at low tip strength, while for Fermi energies associated with faint conductance plateaus, the second-order correction becomes dominant for relatively small potential tip strengths. In accordance with the spatial dependence of the partial local density of states, the largest tip effect occurs in the central part of the constriction, close to the edges. Nanoribbons and nanoconstrictions with zigzag edges exhibit a similar response as in the case of armchair nanostructures, except when the intervalley coupling induced by the tip potential destroys the chiral edge states.

description: Volatile and semi-volatile compounds account for the odors, long valued in the perfumery industry, of the natural product, ambergris. Here we demonstrate application of solid phase micro extraction (SPME) and gas chromatography-mass spectrometry (GC-MS) to headspace analysis of the volatiles and semi-volatiles of jetsam ambergris. The samples collected in 2017/2018, ranged from a black, sticky material from New Zealand, likely recently ejected from a sperm whale, to a white solid found on a beach in Chile and radiocarbon-dated previously to be about 1000 years old. The traces of volatile/semi-volatile compounds extracted included, odorous γ-dihydroionone and odor-free pristane (2,6,10,14-tetramethylpentadecane), as the major constituents. The ratios of these to one another and to many other minor constituents, varied, depending on sample color and age.
The Problem of Sharing Language
Creators: name: Ballnat, Silvana
Publisher: name: Trópos
Year: 2014

description: This paper examines the possible convergences between Gadamer and Davidson regarding the problem of common language needed for mutual understanding by reassessing the source of their difference. It begins with Davidson’s estimation, according to which he agrees largely with Gadamer’s views on language, understanding and communication except for his thesis that communication presupposes sharing language. My analysis of this observation results with the conclusion that the main difference between these two philosophers lies in their understanding of language in general: for Gadamer language is not only a way of communicating meanings as in Davidson’s work, but also it is a bearer of tradition. This text shows how serious appreciation of this dimension of having–language influences the conditions for a dialogue that according to Gadamer are to be found also in the tradition, which is disclosed in language that we learn by learning about world. But the main contribution of the present text consists of its attempt to specify Gadamer’s idea of tradition’s agency through language by means of Davidson’s terms of “prior” and “passing” theories by offering a new account on their relation.

title: Social Remittance Acquisition and Gender Ideologies Among Sudanese Migrants in Glasgow
Creators: name: Hassan, Jamila Elhag
Publisher: name: The Open University
Year: 2022

description: Though the interlink between migration and development is well-established, migrants’ remittances-acquirement experience, particularly social remittances, is relatively overlooked. This study explores immigrants’ experience in acquiring social remittances. It utilises Sen’s Capability Approach to explore whether and how migration impacts progress towards achieving gender equality among Sudanese in Glasgow. The analysis is based on the idea that migration can improve migrants’ financial and intellectual resources that may alter the power relationship between men and women within the household. This change may lead to more gender-equal relationships. The study explores respondents’ experience in two domains with high potential to provide financial and intellectual resources: the labour-market and social interaction. It also considers respondents’ transnational activities (remittances) and their potential to influence respondents’ gender norms. Then the thesis explores whether the change in resources there are changes in respondents’’ gender norms since they arrived in Glasgow by examining changes in sharing three parameters at the household level: authority (head of household and decision-making), labour (provider/ homemaker) and financial resource (control over resources). The research adopts a qualitative approach to gain an insight into immigrants’ experiences. The findings challenge the literature that asserts migration to more gender-equal settings improves immigrants’ gender norms; and provide a better understanding of the contradicting outcomes of other literature. It demonstrates that the acquisition of social remittances is a complex process involving various structural and individual factors. Interaction of these factors differentiates women’s and men’s access to resources and produced little observable change in respondents’ gender relations, while their gender ideologies strongly resist change. The study shows that respondents’ gender ideology and that at the transnational level have essential impacts on maintaining the respondents’ gender norms. Hence, it views gender ideologies as vital in successful policy and/or development interventions.

description: Background: Appropriate depression care is a cancer-care priority. However, many cancer survivors live with undiagnosed and untreated depression. Prostate cancer survivors may be particularly vulnerable, but little is known about their access to depression care. The goal of this study was to describe patterns and predictors of clinical diagnosis and treatment of depression in prostate cancer survivors. Methods: Generalized estimating equations were used to evaluate indicators of self-reported clinical diagnosis and treatment depression as a function of individual-level characteristics within a longitudinal dataset. The data were from a population-based cohort of North Carolinian prostate cancer survivors who were enrolled from 2004 to 2007 on the North Carolina-Louisiana Prostate Cancer Project (N = 1,031), and prospectively followed annually from 2008 to 2011 on the Health Care Access and Prostate Cancer Treatment in North Carolina (N = 805). Results: The average rate of self-reported clinical diagnosis of depression was 44% (95% CI: 39%-49%), which declined from 60% to 40% between prostate cancer diagnosis and 5-7 years later. Factors associated with lower odds of self-reported clinical diagnosis of depression include African-American race, employment, age at enrollment, low education, infrequent primary care visits, and living with a prostate cancer diagnosis for more than 2 years. The average rate of self-reported depression treatment was 62% (95% CI: 55%-69%). Factors associated with lower odds of self-reported depression treatment included employment and living with a prostate cancer diagnosis for 2 or more years. Conclusion: Prostate cancer survivors experience barriers when in need of depression care.

description: Nectandra megapotamica is a tree species that naturally occurs in the Atlantic Forest, Brazil. This paper aims to investigate the chemical composition and in vitro antibacterial, antileishmanial and antiproliferative activities of essential oil from N. megapotamica leaves (NM-EO). It displayed high antibacterial activity against Streptococcus mutans, S. sobrinus, Prevotella nigrescens and Bacteroides fragilis. NM-EO also exhibited high antileishmanial activity against promastigote forms of Leishmania amazonensis. Its antiproliferative activity was evaluated against the following cells: GM07429A (normal cell), MCF-7 (human breast adenocarcinoma), HeLa (human cervical adenocarcinoma) and M059J (human glioblastoma). Its major components, which were determined by GC-FID and GC-MS, were α-bisabolol (13.7%), bicyclogermacrene (10.9%), (E,E)-farnesene (10.6%), Z-caryophyllene (9.5%) and (E)-β-farnesene (7.0%). These results suggest that N. megapotamica, a Brazilian plant, shows initial evidence of a new and alternative source of substances of medicinal interest.

description: We use quantum Monte-Carlo simulations to calculate the phase diagram and the correlation functions for the quantum phase transitions in the two-dimensional dissipative XY model with and without four-fold anisotropy. Without anisotropy, the model describes the superconductor to insulator transition in two-dimensional dirty superconductors. With anisotropy, the model represents the loop-current order observed in the under-doped cuprates and its fluctuations, as well as the fluctuations near the ordering vector in simple models of itinerant antiferromagnets. These calculations test an analytic solution of the model which re-expressed it in terms of topological excitations - the vortices with interactions only in space but none in time, and warps with leading interactions only in time but none in space, as well as sub-leading interactions which are both space and time-dependent. For parameters for which the proliferation of warps dominates the phase transition, the critical fluctuations as a function of the deviation of the dissipation parameter $α$ from its critical value $α_c$ are scale-invariant in imaginary time $τ$ as the correlation length in time $ξ_τ = τ_c e^{|α_c/(α_c-α)|^{1/2}}$ diverges. On the other hand, the spatial correlations develop with a correlation length $ξ_x \approx ξ_0 \log{(ξ_τ)}$, with $ξ_0$ of the order of a lattice constant. The dynamic correlation exponent $z$ is therefore $\infty$. These results are consistent with the phenomenology proposed for the strange metal properties of the cuprates. The Monte-Carlo calculations also directly show warps and vortices. Their density and correlations across the various transitions in the model are calculated and related to those of the order parameter in the original model.

description: Spin-orbit coupling (SOC) plays a crucial role in many branches of physics. In this context, the recent experimental realization of the coupling between spin and linear momentum of ultracold atoms opens a completely new avenue for exploring new spin-related superfluid physics. Here we propose that another important and fundamental SOC, the coupling between spin and orbital angular momentum (SOAM), can be implemented for ultracold atoms using higher-order Laguerre-Gaussian laser beams to induce Raman coupling between two hyperfine spin states of atoms. We study the ground-state phase diagrams of SOAM-coupled Bose-Einstein condensates on a ring trap and explore their applications in gravitational force detection. Our results may provide the basis for further investigation of intriguing superfluid physics induced by SOAM coupling, such as collective excitations.

description: Background Calcium and dairy product intakes have been positively associated with prostate cancer risk. An imbalance in concentrations of calcium and magnesium has been associated with multiple chronic diseases, although few studies have examined the relation with prostate cancer aggressiveness. Objective The goal of this study was to examine the association between dietary intakes of calcium and magnesium, the calcium-To-magnesium ratio (Ca:Mg), and dairy products and prostate cancer aggressiveness. Design Dietary intake was assessed with the use of an interviewer-Administered modified National Cancer Institute Diet History Questionnaire in 996 African American and 1064 European American men with a recent histologically confirmed diagnosis of prostate cancer from the North Carolina-Louisiana Prostate Cancer Project (PCaP). High-Aggressive disease was defined as Gleason sum ≥8, or prostate-specific antigen (PSA) >20 ng/mL, or Gleason score ≥7 and clinical stage T3-T4. The comparison group was all other prostate cancer cases. Logistic regression was used to determine the adjusted ORs and 95% CIs for high-Aggressive prostate cancer by tertile of diet and supplement exposures. Results There was a positive association across tertiles of dietary Ca:Mg intake, with odds of high-Aggressive prostate cancer in the upper tertiles as follows-OR for tertile 2 compared with tertile 1: 1.38 (95% CI: 1.01, 1.88); OR for tertile 3 compared with tertile 1: 1.46 (95% CI: 1.06, 2.02). When stratified by race, the positive association was more pronounced in African American men (OR for tertile 3 compared with tertile 2: 1.62; 95% CI: 1.04, 2.53). Men who reported the highest daily consumption of whole-fat milk had a 74% increased odds of high-Aggressive prostate cancer compared with non-whole-fat milk drinkers, which was attenuated after adjustment for potential mediating factors, such as saturated fat and Ca:Mg intake. Conclusions Among both African American and European American men diagnosed with prostate cancer, a higher Ca:Mg and whole-milk intake were associated with higher odds of high-Aggressive prostate cancer. This study was registered at www.clinicaltrials.gov as NCT03289130.

description: A simple and reliable HPLC method was developed and validated for the quality consistency evaluation of Coffea arabica commercial samples through establishing chromatographic fingerprint and simultaneous determination of bioactive constituents. In the HPLC fingerprint, thirteen common peaks were selected to assess the similarities of coffee samples of different geographical origin. A similarity analysis showed values from 0.434 to 0.950 for the analyzed samples, while quantitation of selected bioactive compounds revealed the highest content of caffeine and the lowest of p-coumaric acid and theobromine in coffee samples. Since phenolic compounds and alkaloids are commonly recognized as natural antioxidants, the antioxidant activity of coffee extracts was also evaluated. The correlation analysis and principal component analysis indicated that the combination of HPLC fingerprint and quantitative analysis can be readily utilized as a quality assessment tool for coffee and other plant products.
