description: We argue that supermassive black hole growth in AGN occurs via sequences of randomly--oriented accretion discs with angular momentum limited by self--gravity. These stably co-- or counter--align with the black hole spin with almost equal frequency. Accretion from these discs very rapidly adjusts the hole's spin parameter to average values $\bar a \sim 0.1-0.3$ (the precise range depending slightly on the disc vertical viscosity coefficient $α_2$) from any initial conditions, but with significant fluctuations ($Δa\sim \pm 0.2$) about these. We conclude (a) AGN black holes should on average spin moderately, with the mean value $\bar a$ decreasing slowly as the mass increases; (b) SMBH coalescences leave little long--term effect on $\bar a$; (c) SMBH coalescence products in general have modest recoil velocities, so that there is little likelihood of their being ejected from the host galaxy; (d) black holes can grow even from stellar masses to $\sim 5\times 10^9 \msun$ at high redshift $z\sim 6$; (e) jets produced in successive accretion episodes can have similar directions, but after several episodes the jet direction deviates significantly. Rare examples of massive holes with larger spin parameters could result from prograde coalescences with SMBH of similar mass, and are most likely to be found in giant ellipticals. We compare these results with observation. (abridged)

description: Let F_2 be a free group of rank 2. We prove that there is an algorithm that decides whether or not, for given two elements u, v of F_2, u and v are translation equivalent in F_2, that is, whether or not u and v have the property that the cyclic length of phi(u) equals the cyclic length of phi(v) for every automorphism phi of F_2. This gives an affirmative solution to problem F38a in the online version (http://www.grouptheory.info) of [1] for the case of F_2.

description: The interplay of crystal symmetry, magnetism, band topology and electronic correlation can be the origin of quantum phase transitions in condensed matter. Particularly, square-lattice materials have been serving as a versatile platform to study the rich phenomena resulting from that interplay. In this work, we report a detailed magnetic study on the square-lattice based magnetic topological semimetals GdSb_{x}Te_{2-x-δ}. We report the H-T magnetic phase diagrams along three crystallographic orientations and show that, for those materials where a charge density wave distortion is known to exist, many different magnetic phases are identified. In addition, the data provides a clue to the existence of an antiferromagnetic skyrmion phase, which has been theoretically predicted but not experimentally confirmed in a bulk material yet.
Efficiency of farabloc in reduction of delayed onset muscle soreness
Creators: name: Zhang, Jian
Publisher: name: University of British Columbia
Year: 2009

description: Farabloc is made of a series of ultra thin steel threads woven into a linen fabric. It is based on the same principle as the "Farady Cage" to shield external electromagnetic influences. The product was shown in previous research to have a beneficial effect on the reduction of phantom limb pain. However, whether this product can be used in muscle pain is still a question. The aim of this study is to test the efficiency of Farabloc in reducing delayed onset muscles- soreness (DOMS). It was proposed that Farabloc therapy would reduce exercise induced muscle soreness following injury. The first hypothesis is that exercise induced muscle soreness causes a local inflammatory response in the quadriceps muscle and Farabloc therapy will reduce the inflammatory response and pain sensation. The second hypothesis is that using Farabloc will accelerate the return of eccentric strength, reduced by DOMS. The experiment created DOMS, utlizing exercise on a Biodex unit, with a single blind crossover design and assessed the effectiveness of Farabloc on response of inflammation, strength and pain. Twenty subjects were divided into two groups—A group and B group. Both groups were treated by Farabloc or placebo in two experimental stages. All subjects were tested in a single blind design and covered their entire thigh area with either a 2 layer Farabloc or placebo wrap immediately following exposure to the noxious exercise. Pain was measured utlizing a visual analog scale and strength was measured on the BIODEX unit. Muscle damage and response of inflammation assessed by blood assay of creatine kinase (CK), leukocyte, neutrophil, myoglobin and malondialdehyde (MDA). Tests were taken at intervals over 5 days. Each stage of the experiment had four periods consisting of rest, exercise, treatment and post treatment. To consider the correlation between the variables statistical analyses used three separate two way MANOVA with repeated measures and one ANOVA with repeated measures on the parameters of different time periods. Significant defferences have found between stage 1 A group (farabloc treatment) and B group (placebo treatment) for the MANOVA analyses for pain and strength testing (p<0.001), CK with myglobin tests (p<0.001) and the MANOVA of WBC with neutrophil tests (p=0.003), and also the ANOVA analyses for MDA. In stage 2 the MANOVA of pain and strength testing (p=0.221), CK with myglobin (p=0.460) and leukocyte with neutrophil (p=0.204) had no significant differences between B group (Farabloc) and A group (placebo) but there was significant difference in ANOVA of MDA test between the two groups. The crossover studies showed there were significant differences between Farabloc treatment and placebo treatment in both groups (p<0.05) except for the MANOVA analyses for leukocyte with neutrophil in A group. It was concluded that the Farabloc appears to positively effect the recovery from exercise-induced muscle soreness.
REEEM-D2.3_Methodology for linking technology innovation to energy system models
Creators: name: REEEM Project
Publisher: name: Zenodo
Year: 2019

description: This report aims at synopsising a novel methodology to link technology innovation to energy system models. The methodology leads to the development and investigation of pathways for the transition of the EU energy system based on different technological advancements. This methodology has been developed (and will be further improved) under the scope of the EUfunded REEEM project (http://www.reeem.org/). The analysis builds upon the expertise in the field of technology innovation assessment coupled with the experience in energy systems and macroeconomic modelling. The main challenge pertaining to this attempt is the quantification of the qualitative information derived from the innovation assessment platform and subsequently the process of feeding this data into the aforementioned models. What makes it particularly demanding is the fact that the models and the assessment tools have different level of analysis. In turn, the such interlinked innovation assessment platform and energy system models lead to the development and investigation of pathways for the transition of the energy system of the EU based on different technological advancements.

description: Our goal in this paper is to extend the theory of quasi-exactly solvable Schrodinger operators beyond the Lie-algebraic class. Let $\cP_n$ be the space of n-th degree polynomials in one variable. We first analyze "exceptional polynomial subspaces" which are those proper subspaces of $\cP_n$ invariant under second order differential operators which do not preserve $\cP_n$. We characterize the only possible exceptional subspaces of codimension one and we describe the space of second order differential operators that leave these subspaces invariant. We then use equivalence under changes of variable and gauge transformations to achieve a complete classification of these new, non-Lie algebraic Schrodinger operators. As an example, we discuss a finite gap elliptic potential which does not belong to the Treibich-Verdier class.

description: Dark energy and dark matter are the dominant sources in the evolution of the late universe. They are currently only indirectly detected via their gravitational effects, and there could be a coupling between them without violating observational constraints. We investigate the background dynamics when dark energy is modelled as exponential quintessence, and is coupled to dark matter via simple models of energy exchange. We introduce a new form of dark sector coupling, which leads to a more complicated dynamical phase space and has a better physical motivation than previous mathematically similar couplings.

description: Weather derivatives are contingent claims with payoff based on a pre-specified weather index. Firms exposed to weather risk can transfer it to financial markets via weather derivatives. We develop a utility-based model for pricing baskets of weather derivatives under default risk on the issuer side in over-the-counter markets. In our model, agents maximise the expected utility of their terminal wealth, while they dynamically rebalance their weather portfolios over a finite investment horizon. Using dynamic programming approach, we obtain semi-closed forms for the equilibrium prices of weather derivatives and for the optimal strategies of the agents. We give an example on how to price rainfall derivatives on selected stations in China in the universe of a financial investor and a weather exposed crop insurer.

description: The possibility of soliton self-compression of ultrashort laser pulses down to the few-cycle regime in photonic crystal fibers is numerically investigated. We show that efficient sub-two-cycle temporal compression of nanojoule-level 800 nm pulses can be achieved by employing short (typically 5-mm-long) commercially available photonic crystal fibers and pulse durations of around 100 fs, regardless of initial linear chirp, and without the need of additional dispersion compensation techniques. We envisage applications in a new generation of compact and efficient sub-two cycle laser pulse sources.

description: We propose a novel pathology-sensitive deep learning model (PS-DeVCEM) for frame-level anomaly detection and multi-label classification of different colon diseases in video capsule endoscopy (VCE) data. Our proposed model is capable of coping with the key challenge of colon apparent heterogeneity caused by several types of diseases. Our model is driven by attention-based deep multiple instance learning and is trained end-to-end on weakly labeled data using video labels instead of detailed frame-by-frame annotation. The spatial and temporal features are obtained through ResNet50 and residual Long short-term memory (residual LSTM) blocks, respectively. Additionally, the learned temporal attention module provides the importance of each frame to the final label prediction. Moreover, we developed a self-supervision method to maximize the distance between classes of pathologies. We demonstrate through qualitative and quantitative experiments that our proposed weakly supervised learning model gives superior precision and F1-score reaching, 61.6% and 55.1%, as compared to three state-of-the-art video analysis methods respectively. We also show our model's ability to temporally localize frames with pathologies, without frame annotation information during training. Furthermore, we collected and annotated the first and largest VCE dataset with only video labels. The dataset contains 455 short video segments with 28,304 frames and 14 classes of colorectal diseases and artifacts. Dataset and code supporting this publication will be made available on our home page.

description: Josephson junctions and junction arrays are well studied devices in superconductivity. With external magnetic fields one can modulate the phase in a long junction and create traveling, solitonic waves of magnetic flux, called fluxons. Today, it is also possible to device two different types of junctions: depending on the sign of the critical current density, they are called 0- or pi-junction. In turn, a 0-pi junction is formed by joining two of such junctions. As a result, one obtains a pinned Josephson vortex of fractional magnetic flux, at the 0-pi boundary. Here, we analyze this arrangement of superconducting junctions in the context of an atomic bosonic quantum gas, where two-state atoms in a double well trap are coupled in an analogous fashion. There, an all-optical 0-pi Josephson junction is created by the phase of a complex valued Rabi-frequency and we a derive a discrete four-mode model for this situation, which qualitatively resembles a semifluxon.

description: Magnitude-limited samples have shown that 20-25 per cent of cataclysmic variables contain white dwarfs with magnetic fields of Mega Gauss strength, in stark contrast to the approximately 5 per cent of single white dwarfs with similar magnetic field strengths. Moreover, the lack of identifiable progenitor systems for magnetic cataclysmic variables leads to considerable challenges when trying to understand how these systems form and evolve. Here we present a sample of six magnetic white dwarfs in detached binaries with low-mass stellar companions where we have constrained the stellar and binary parameters including, for the first time, reliable mass estimates for these magnetic white dwarfs. We find that they are systematically more massive than non-magnetic white dwarfs in detached binaries. These magnetic white dwarfs generally have cooling ages of more than 1 Gyr and reside in systems that are very close to Roche-lobe filling. Our findings are more consistent with these systems being temporarily detached cataclysmic variables, rather than pre-cataclysmic binaries, but we cannot rule out the latter possibility. We find that these systems can display unusual asymmetric light curves that may offer a way to identify them in larger numbers in future. Seven new candidate magnetic white dwarf systems are also presented, three of which have asymmetric light curves. Finally, we note that several newly identified magnetic systems have archival spectra where there is no clear evidence of magnetism, meaning that these binaries have been previously missed. Nevertheless, there remains a clear lack of younger detached magnetic white dwarf systems.

simple dismantling of colonial habits and modes of life. Nowhere are the complexities
and ambiguities of this dialogue more evident than in the vicissitudes of cricket in
those countries that were once part of the British Empire. In the Indian case, the
cultural aspects of decolonization deeply affect every domain of public life, from
language and the arts to ideas about political representation and economic justice. ln
every major public debate in contemporary India, one underlying strand is always the
question of what to do with the shreds and patches of the Colonial heritage. Some of
these patches are institutional; others are ideological and aesthetic.

Computation of the Fourier parameters of RR Lyrae stars by template fitting

name: Kupi, G.
Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Due to the importance of accurate Fourier parameters, we devise a method that is more appropriate for deriving these parameters on low-quality data than the traditional Fourier fitting. Based on the accurate light curves of 248 fundamental mode RR Lyrae stars, we test the power of a full-fetched implementation of the template method in the computation of the Fourier decomposition. The applicability of the method is demonstrated also on datasets of filter passbands different from that of the template set. We examine in more detail the question of the estimation of Fourier- based iron abundance [Fe/H] and average brightness. We get, for example, for light curves sampled randomly in 30 data points with sigma=0.03 mag observational noise that optimized direct Fourier fits yield sigma_[Fe/H]=0.33, whereas the template fits result in sigma_[Fe/H]=0.18. Tests made on the RR Lyrae database of the Large Magellanic Cloud (LMC) of the Optical Gravitational Lensing Experiment (OGLE) support the applicability of the method on real photometric time series. These tests also show that the dominant part of error in estimating the average brightness comes from other sources, most probably from crowding effects, even for under-sampled light curves.

Niels Bohr, objectivity, and the irreversibility of measurements

description: The only acceptable reason why measurements are irreversible and outcomes definite is the intrinsic definiteness and irreversibility of human sensory experience. While QBists deserve credit for their spirited defense of this position, Niels Bohr urged it nearly a century ago, albeit in such elliptic ways that the core of his message has been lost or distorted beyond recognition. Then as now, the objectivity of empirical science was called into question. It was defended by Bohr along the lines of Kant's (then) revolutionary theory of science, according to which the possibility of empirical science hinges on the possibility of thinking of experiences as experiences of a system of interacting, re-identifiable objects. What Bohr added to Kant's theory was his insight that empirical knowledge was not necessarily limited to what is directly accessible to the senses, and that, therefore, it does not have to be solely a knowledge of objects of sensible intuition. It can also be a knowledge of phenomena that are not objects of sensible intuition but instead are constituted by experimental contexts, which are objects of sensible intuition. Bohr's grounding of objectivity (or the objectivity consistent with quantum mechanics), however, is weaker than Kant's (or the objectivity consistent with Newtonian physics). This conclusion is based on an examination of Bohr's intentions in appealing to irreversible amplification effects or the sufficient size and weight of the measurement apparatus.

Subjects: Farm Settlement, Revitalization, Unemployment Reduction

description: This thesis is on farm settlement scheme revitalization and unemployment reduction in Edo state from 2007 till date. The Farm settlement scheme, originally designed to promote agricultural development and employment generation, has deteriorated over time. Essentially, the research investigated the factors accounting for the deterioration of the scheme and proffer solutions that would help to revitalize it. To guide this study, three research questions and three objectives were formulated. Related literature comprising the conceptual and empirical were reviewed. The study adopted the conflict theory by Karl Marx and The High Payoff Input Model of Agricultural Development by Schultz. The study relied on mixed research design comprising the quantitative and qualitative methods. The questionnaire was distributed through snowballing sampling technique to collect the quantitative data. The purposive sampling technique was used to select participants for the key person’s interview and focus group discussion. The population of the study was 444 which is the current population of farmers in the three farm settlements at the time of this study, while the sample size is 448.  Simple percentage was used to analyze the socio-demographic data, while Mean and Standard Deviation was used to analyze the research questions. The KPIs and FGDs were transcribed and analyzed thematically. The results revealed that the farm settlement scheme created lots of employment in the past in Edo state as more than four thousand jobs were created annually. It was also revealed that several factors such as massive insecurity, inadequate infrastructures, amongst others, accounted for the inability of the scheme to address unemployment in contemporary Edo state. From the findings, the thesis concludes that the revitalization of the farm settlement scheme would help tremendously in reducing the unemployment challenge in Edo state. The thesis recommends amongst others, that government should tackle insecurity, provide the necessary infrastructures, provide adequate funding, and provide modern farming equipment.

description: We determine new bounds on the entries of Gorenstein Hilbert functions, both in any fixed codimension and asymptotically. Our first main theorem is a lower bound for the degree $i+1$ entry of a Gorenstein $h$-vector, in terms of its entry in degree $i$. This result carries interesting applications concerning unimodality: indeed, an important consequence is that, given $r$ and $i$, all Gorenstein $h$-vectors of codimension $r$ and socle degree $e\geq e_0=e_0(r,i)$ (this function being explicitly computed) are unimodal up to degree $i+1$. This immediately gives a new proof of a theorem of Stanley that all Gorenstein $h$-vectors in codimension three are unimodal. Our second main theorem is an asymptotic formula for the least value that the $i$-th entry of a Gorenstein $h$-vector may assume, in terms of codimension, $r$, and socle degree, $e$. This theorem broadly generalizes a recent result of ours, where we proved a conjecture of Stanley predicting that asymptotic value in the specific case $e=4$ and $i=2$, as well as a result of Kleinschmidt which concerned the logarithmic asymptotic behavior in degree $i= \lfloor \frac{e}{2} \rfloor $.

Subjects: “sport”;“pugilato”;“Primo Carnera”;“propaganda”;“fascismo”;“fumetto”

description: This essay focuses on the process of entrechment in the Italian collective imagination of the figure of Primo Carnera, World Heavyweight Champion from 1933 to 1934, and on the evolution of his image from the years of his first wins to the beginning of XXI century. More specifically, the essay makes visible how the mythization of Carnera had spontaneously developed long before the Italian press started to extol the successes of the boxer, and how the Fascism subsequently tried to appropriate the image of Carnera – modifying some of its fundamental traits – in order to use it as a powerful tool of regime’s propaganda, especially during the war years. In the end, the essay shows how the figure of Carnera regained favour after the fall of the fascist regime reappropriating (or, more rarely, being distorted of) its original traits.

The study has been carried out through the comparison of a selection of cartoons, caricatures and illustration from the popular press dedicated to Carnera, official portrayals of him during the fascist regime and comic books more or less expressely inspired by the figure of the boxer.

description: Hadal, more than 6000 m deep shipborne Sea-Bird Electronics SBE 911plus Conductivity Temperature Depth (CTD) data are obtained using two different systems in the vicinity of the Earths deepest point, in the Challenger Deep, Mariana Trench 14 years apart. Below 7000 m in very weakly density stratified waters, the salinity data from both sets show an artificial increase with depth of about 10-6 g kg-1 m-1 that is not covered by the SBE linear pressure correction to the conductivity data. With the aid of independent water sample data, salinity is corrected and an additional algorithm for the pressure correction on conductivity data is formulated. The corrected salinity data still weakly increase with depth, together with a decrease in temperature, which may point at an influx of dense modified Antarctic bottom water. The corrected density variations with depth are used in calculations of deep turbulence values.

anni fa e si trovano fra i comuni di Tora e Piccilli, in località Foresta nella provincia di
Caserta. Tre uomini che avevano una misura di piede 36 (forse dei ragazzi o forse una
variante minore dell’Homo heildelbergensis di statura più alta) camminarono su uno
strato di fanghiglia calda e lasciarono i segni del loro passaggio. Non correvano,
altrimenti la distanza fra le impronte sarebbe stata più ampia, semplicemente
camminavano, anzi ad un certo momento, poiché il sentiero che percorrevano
scendeva verso valle, uno di essi scivolò ed ancora oggi si vede l'impronta della mano
lungo il pendio per appoggiarsi e non cadere del tutto. Subito dopo il loro passaggio,
un vento secco asciugò le impronte e quel gesto non svanì nel nulla ma, come una
fotografia antica, rimase incerto e vivo nel tempo.

description: Atomic wave packets loaded into a phase-modulated vertical optical-lattice potential exhibit a coherent delocalization dynamics arising from intraband transitions among Wannier-Stark levels. Wannier-Stark intraband transitions are here observed by monitoring the in situ wave-packet extent. By varying the modulation frequency, we find resonances at integer multiples of the Bloch frequency. The resonances show a Fourier-limited width for interrogation times up to 2 s. This can also be used to determine the gravity acceleration with ppm resolution.

description: A protein structure is represented as a network of residues whereby edges are determined by intra-molecular contacts. We introduce inhomogeneity into these networks by assigning each edge a weight that is determined by amino-acid pair potentials. Two methodologies are utilized to calculate the average path lengths (APLs) between pairs: To minimize (i) the maximum weight in the strong APL, and (ii) the total weight in the weak APL. We systematically screen edges that have higher than a cutoff potential and calculate the shortest APLs in these reduced networks, while keeping chain connectivity. Therefore, perturbations introduced at a selected region of the residue network propagate to remote regions only along the non-screened edges that retain their ability to disseminate the perturbation. The shortest APLs computed from the reduced homogeneous networks with only the strongest few non-bonded pairs closely reproduce the strong APLs from the weighted networks. The rate of change in the APL in the reduced residue network as compared to its randomly connected counterpart remains constant until a lower bound. Upon further link removal, this property shows an abrupt increase, towards a random coil behavior. Under different perturbation scenarios, diverse optimal paths emerge for robust residue communication.

Imagined solidarities: Black liberal internationalism and the National Council of Negro Women from Afro-Asian to Pan-African unity, 1935-1975

description: “Imagined Solidarities” examines Black women’s efforts to reform liberal internationalism in the mid-twentieth century. Focusing on one of the largest African American women’s organizations, the National Council of Negro Women (the Council), I show how women such as Sue Bailey Thurman, Mary McLeod Bethune, Edith Sampson, Vivian Carter Mason, Dorothy Ferebee, and Dorothy Height pursued racial and gender justice domestically and worldwide through collaboration with Asian, African, and African-descended women. Council women forged friendships and political partnerships with Vijaya Lakshmi Pandit and Rustomji Faridoonji of India, Begum Ra’ana Liaquat Ali Khan of Pakistan and with prominent African and African-descended women activists including Flora Azikiwe of Nigeria and Evelyn Amarteifio of Ghana. These collaborations had political consequences domestically and internationally. At the same time, Council women reimagined liberalism through what I call a pleasurable internationalism. I argue that their worldviews and commitments to American identity and US hegemony complicated, limited, and, at times, even thwarted these efforts. I apply Black feminist theoretical frameworks on a multi- archival source base that combines personal and organizational papers as well as published memoirs. My approach reveals how Council leaders and their allies relied on the intimate domain for their attempts to make the world anew. By studying Council leaders and their allies, I expand scholarship on twentieth-century Black internationalism that focuses primarily on Black radical and male liberal activists. In so doing, I offer an account of sustained international activities beginning before World II, continuing through the anticommunist suppression of the 1950s to the 1975 United Nations-sponsored International Women’s Year activities.

description: Constraints on spin observables coming from discrete symmetries such as P, C, T and identical particles may be divided in two types: 1) classical ones, which insure the invariance of the cross sections under the symmetry operation; 2) non-classical ones, which can only be obtained at the level of amplitudes. Similarly, positivity constraints can be divided into classical and non-classical constraints. The former insure the positivity of the cross section for arbitrary individual polarisations of the external particles, the latter extend this requirement to the case of entangled external spins. The domain of classical positivity is shown to be dual to the domain of separability
Social Identity and Consumer Preference Formation for High Involvement Products: A Study of Nigerians in the UK
Creators: name: Ndi Wanki, Emmanuel
Publisher: name: University of East London
Year: 2018

description: One stream of quest by scholars for knowledge development draws from the notion that groups and group behaviour lie at the heart of human society and proposes a social group approach. The notion contends that individuals live, work, and interact in groups and as a result are collaborative architects of the social world they inhabit. Advocates underline the need to improve the general understanding of consumer preference formation theory and the role of social groups’ behaviour on the consumption behaviour of individual members of social groups. Inspired by research gaps in this regard, this research examines how social identity / collective identity influences the preference formation of UK based Nigerians (a relatively unexplored social group) for high involvement products. Thus, this study conceptualised social identity / collective identity on the basis of nationality and ethnicity as aspects of consumer social identity. This study has utilised mainstream literature and conceptualised a framework (motivated by research gaps) that draws from identity, self-concept, extended self, culture (and acculturation), social embeddedness, symbolic consumption (clothing, necklaces, cars and mobile phones), networking [educational and employment], interaction and intermingling with other cultures. Exploratory and qualitative research approaches are used in this study and the research has followed interpretive logic that combines semi-structure interviews and observation. Based on the majority of participants in this study, culture plays a significant role in shaping the mindset of UK based Nigerians, and as a result social identity congruence behaviour is common within the Nigerian social community in the UK. Therefore, social identity congruence preference formation behaviour for high involvement products is high among UK based Nigerians. For some members of this social community, exhibiting such social identity congruence behaviour in their high involvement products preference formation is a sine-qua-non, a consequence of which is that they do not mind putting themselves through financial stress because they want to blindly follow the bandwagon. Based on purposive sampling, 34 participants were interviewed. The findings asserted that preference formation of UK based Nigerians for high involvement products is conditioned not only by social identity, but also by personal identity features, which includes personal values, religiosity-based values, and beyond own cultural domain imbibed values through networking. This study has contributed to the illumination of behavioural tendencies, social identity, factors that shape and moderate the self-concept and importance attached to membership of identity groups, and how these influence preference formations for high involvement products.

description: We present the first experimental demonstration of the maximum confidence measurement strategy for quantum state discrimination. Applying this strategy to an arbitrary set of states assigns to each input state a measurement outcome which, when realized, gives the highest possible confidence that the state was indeed present. The theoretically optimal measurement for discriminating between three equiprobable symmetric qubit states is implemented in a polarization-based free-space interferometer. The maximum confidence in the measurement result is 2/3. This is the first explicit demonstration that an improvement in the confidence over the optimal minimum error measurement is possible for linearly dependent states.

description: Galaxy clusters exhibit a rich morphology during the early and intermediate stages of mass assembly, especially beyond their boundary. A classification scheme based on shapefinders deduced from the Minkowski functionals is examined to fully account for the morphological diversity of galaxy clusters, including relaxed and merging clusters, clusters fed by filamentary structures, and cluster-pair bridges. These configurations are conveniently treated with idealised geometric models and analytical formulae, some of which are novel. Examples from CLASH and LC$^2$ clusters and observed cluster-pair bridges are discussed.

description: We report a measurement of the cold collision frequency shift in atomic hydrogen gas adsorbed on the surface of superfluid 4He at T<=90 mK. Using two-photon electron and nuclear magnetic resonance in 4.6 T field we separate the resonance line shifts due to the dipolar and exchange interactions, both proportional to surface density sigma. We find the clock shift Delta v_c = -1.0(1)x10^-7 Hz cm^-2 x sigma, which is about 100 times smaller than the value predicted by the mean field theory and known scattering lengths in the 3D case.

description: Tidally dissolved globular clusters form thin stellar streams that preserve a historical record of their past evolution. We report a radial velocity dispersion of $2.3\pm0.3\,\textrm{km}\,\textrm{s}^{-1}$ in the GD-1 stellar stream using a sample of 43 spectroscopically confirmed members. The GD-1 velocity dispersion is constant over the surveyed $\approx15^\circ$ span of the stream. We also measured velocity dispersion in the spur adjacent to the main GD-1 stream, and found a similar value at the tip of the spur. Surprisingly, the region of the spur closer to the stream appears dynamically colder than the main stream. An unperturbed model of the GD-1 stream has a velocity dispersion of $\approx0.6\,\textrm{km}\,\textrm{s}^{-1}$, indicating that GD-1 has undergone dynamical heating. Stellar streams arising from globular clusters, which prior to their arrival in the Milky Way, orbited a dwarf galaxy with a cored density profile are expected to have experienced the amount of heating required to match the velocity dispersion observed in GD-1. This suggests that GD-1 has been accreted and that imprints of its original host galaxy, including the inner slope of its dark-matter halo, remain observable in the stream today.
