description: Single molecule magnets straddle the classical and quantum mechanical worlds, displaying many fascinating phenomena. They may have important technological applications in information storage and quantum computation. We review the physical properties of two prototypical molecular nanomagnets, Mn_12-acetate and Fe_8: each behaves as a rigid, spin-10 object, and exhibits tunneling between up and down directions. As temperature is lowered, the spin reversal process evolves from thermal activation to pure quantum tunneling. At low temperatures, magnetic avalanches occur in which the magnetization of an entire sample rapidly reverses. We discuss the important role that symmetry-breaking fields play in driving tunneling and in producing Berry-phase interference. Recent experimental advances indicate that quantum coherence can be maintained on time scales sufficient to allow a meaningful number of quantum computing operations to be performed. Efforts are underway to create monolayers and to address and manipulate individual molecules.

description: We consider semi-classical black holes and related re-scalings with N massless fields. For a given semi-classical solution of an N = 1 universe, we can find other solution of a large N universe by the re-scaling. After the re-scaling, any curvature quantity takes a sufficiently small value without changing its causal structure. Via the re-scaling, we argue that black hole complementarity for semi-classical black holes cannot provide a fundamental resolution of the information loss problem, and the violation of black hole complementarity requires sufficiently reasonable amounts of N. Such N might be realized from some string inspired models. Finally, we claim that any fundamental resolution of the information loss problem should resolve the problem of the singularity.

description: Solar activity cycle varies in amplitude. The last Cycle 24 is the weakest in the past century. Sun's activity dominates Earth's space environment. The frequency and intensity of the Sun's activity are accordant with the solar cycle. Hence there are practical needs to know the amplitude of the upcoming Cycle 25. The dynamo-based solar cycle predictions not only provide predictions, but also offer an effective way to evaluate our understanding of the solar cycle. In this article we apply the method of the first successful dynamo-based prediction developed for Cycle 24 to the prediction of Cycle 25, so that we can verify whether the previous success is repeatable. The prediction shows that Cycle 25 would be about 10% stronger than Cycle 24 with an amplitude of 126 (international sunspot number version 2.0). The result suggests that Cycle 25 will not enter the Maunder-like grand solar minimum as suggested by some publications. Solar behavior in about four to five years will give a verdict whether the prediction method captures the key mechanism for solar cycle variability, which is assumed as the polar field around the cycle minimum in the model.

description: The ongoing fourth Industrial Revolution depends mainly on robust Industrial Cyber-Physical Systems (ICPS). ICPS includes computing (software and hardware) abilities to control complex physical processes in distributed industrial environments. Industrial agents, originating from the well-established multi-agent systems field, provide complex and cooperative control mechanisms at the software level, allowing us to develop larger and more feature-rich ICPS. The IEEE P2660.1 standardisation project, "Recommended Practices on Industrial Agents: Integration of Software Agents and Low Level Automation Functions" focuses on identifying Industrial Agent practices that can benefit ICPS systems of the future. A key problem within this project is identifying the best-fit industrial agent practices for a given ICPS. This paper reports on the design and development of a tool to address this challenge. This tool, called IASelect, is built using graph databases and provides the ability to flexibly and visually query a growing repository of industrial agent practices relevant to ICPS. IASelect includes a front-end that allows industry practitioners to interactively identify best-fit practices without having to write manual queries.

This generalizes a result of Sokal (cond-mat/9904146) that applies only within the complex antiferromagnetic regime |1+w_e| \le 1. Our proof uses the polymer-gas representation of the multivariate Tutte polynomial together with the Penrose identity.

description: Excerpts from the report: Pronounced changes have taken place in the food distribution industry, especially since World War II. The expansion in numbers of supermarkets, the decline in numbers of small groceries and specialty food stores, and the increasing concentration of ownership and control of retail outlets have significant implications to growers. These developments have contributed to a growing interest in fruit and vegetable marketing associations as a means for improving the competitive position of producers. Farmer Cooperative Service made this study to: (1) Describe the organizational structure and operating procedures of various types of grower-controlled fresh fruit and vegetable marketing organizations and (2) provide fruit and vegetable producers with guides useful in establishing or improving group marketing programs. Producers requested this type of information in recognition of their need to change from individual grower marketing to a group basis.

The effects of hormonal and early surgical bursectomy on the thymic development of the chick embryo
Creators: name: Dixon, Dennis Kent
Publisher: name: University of British Columbia
Year: 2010

description: Hormonal bursectomy significantly reduces thymocyte numbers in 18 day embryonic thymuses when it is carried out on or before the fifth day of incubation. Early embryonic surgical bursectomy (at 72 hours in ovo) similarly reduces thymocyte numbers. When hormonal bursectomy and early embryonic surgical bursectomy are combined, the effects appear to be additive producing a nearly two-fold depression of thymocyte numbers. Such results suggest that hormonal bursectomy, on or before the fifth day of incubation, and early surgical bursectomy affect thymocyte numbers by two different mechanisms. It is postulated that the effects of hormonal bursectomy prior to the fifth day of incubation represent a testosterone-thymus interaction. This interaction appears to result in an interference with the initial population of the thymus by migrating stem cells, resulting in a reduction of the numbers of thymocytes. Early surgical bursectomy would presumably circumvent such an interaction. It is suggested that early surgical bursectomy does indeed reduce thymocyte numbers by removing a potential bursal contribution to thymocyte numbers. Based on the evidence of this study and other investigations, it is suggested that the bursa contributes significantly to a secondary inflow of thymic stem cells occurring later in the embryonic period.

description: Future large segmented space telescopes and their coronagraphic instruments are expected to provide the resolution and sensitivity to observe Earth-like planets with a 10^10 contrast ratio at less than 100 mas from their host star. Advanced coronagraphs and wavefront control methods will enable the generation of high-contrast dark holes in the image of an observed star. However, drifts in the optical path of the system will lead to pointing errors and other critical low-order aberrations that will prevent maintenance of this contrast. To measure and correct for these errors, we explore the use of a Zernike wavefront sensor (ZWFS) in the starlight rejected and filtered by the focal plane mask of a Lyot-type coronagraph. In our previous work, the analytical phase reconstruction formalism of the ZWFS was adapted for a filtered beam. We now explore strategies to actively compensate for these drifts in a segmented pupil setup on the High-contrast imager for Complex Aperture Telescopes (HiCAT). This contribution presents laboratory results from closed-loop compensation of bench internal turbulence as well as known introduced aberrations using phase conjugation and interaction matrix approaches. We also study the contrast recovery in the image plane dark hole when using a closed loop based on the ZWFS.

description: One possible channel for the formation of dwarf galaxies involves birth in the tidal tails of interacting galaxies. We report the detection of a bright UV tidal tail and several young tidal dwarf galaxy candidates in the post-merger galaxy NGC 4922 in the Coma cluster. Based on a two-component population model (combining young and old stellar populations), we find that the light of tidal tail predominantly comes from young stars (a few Myr old). The Galaxy Evolution Explorer (GALEX) ultraviolet data played a critical role in the parameter (age and mass) estimation. Our stellar mass estimates of the tidal dwarf galaxy candidates are ~ 10^{6-7} M_sun, typical for dwarf galaxies.

description: Charts are used to measure relative success for a large variety of cultural items. Traditional music charts have been shown to follow self-organizing principles with regard to the distribution of item lifetimes, the on-chart residence times. Here we examine if this observation holds also for (a) music streaming charts (b) book best-seller lists and (c) for social network activity charts, such as Twitter hashtags and the number of comments Reddit postings receive. We find that charts based on the active production of items, like commenting, are more likely to be influenced by external factors, in particular by the 24 hour day-night cycle. External factors are less important for consumption-based charts (sales, downloads), which can be explained by a generic theory of decision-making. In this view, humans aim to optimize the information content of the internal representation of the outside world, which is logarithmically compressed. Further support for information maximization is argued to arise from the comparison of hourly, daily and weekly charts, which allow to gauge the importance of decision times with respect to the chart compilation period.

description: Quantum phase transitions are a ubiquitous many-body phenomenon that occurs in a wide range of physical systems, including superconductors, quantum spin liquids, and topological materials. However, investigations of quantum critical systems also represent one of the most challenging problems in physics, since highly correlated many-body systems rarely allow for an analytic and tractable description. Here we present a Lee-Yang theory of quantum phase transitions including a method to determine quantum critical points which readily can be implemented within the tensor network formalism and even in realistic experimental setups. We apply our method to a quantum Ising chain and the anisotropic quantum Heisenberg model and show how the critical behavior can be predicted by calculating or measuring the high cumulants of properly defined operators. Our approach provides a powerful formalism to analyze quantum phase transitions using tensor networks, and it paves the way for systematic investigations of quantum criticality in two-dimensional systems.

description: We determine all finite p-groups that admit a faithful, self-similar action on the p-ary rooted tree such that the first level stabilizer is abelian. A group is in this class if and only if it is a split extension of an elementary abelian p-group by a cyclic group of order p. The proof is based on use of virtual endomorphisms. In this context the result says that if G is a finite p-group with abelian subgroup H of index p, then there exists a virtual endomorphism of G with trivial core and domain H if and only if G is a split extension of H and H is an elementary abelian p-group.

description: The usual ambient space approach to conformal fields is based on identifying the d-dimensional conformal space as the Dirac projective hypercone in a flat d+2-dimensional ambient space. In this work, we explicitly concentrate on singletons of any integer spin and propose an approach that allows one to have both locality and conformal symmetry manifest. This is achieved by using the ambient space representation in the fiber rather than in spacetime. This approach allows us to characterize a subalgebra of higher symmetries for any bosonic singleton, which is a candidate higher-spin algebra for mixed symmetry gauge fields on anti de Sitter spacetime. Furthermore, we argue that this algebra actually exhausts all higher symmetries.

description: The idea of the global gravitational effect as the source of cosmological redshift was considered by de Sitter (1916, 1917), Eddington (1923), Tolman (1929) and Bondi (1947). Also Hubble (1929) called the discovered distance-redshift relation as "De Sitter effect". For homogeneous matter distribution cosmological gravitational redshift is proportional to square of distance: z_grav ~ r^2. However for a fractal matter distribution having the fractal dimension D=2 the global gravitational redshift is the linear function of distance: z_grav ~ r, which gives possibility for interpretation of the Hubble law without the space expansion. Here the field gravity fractal cosmological model (FGF) is presented, which based on two initial principles. The first assumption is that the Feynman's field gravity approach describes the gravitational interaction, which delivers a natural basis for the conceptual unity of all fundamental physical interactions within the framework of the relativistic and quantum fields in Minkowski space. The second hypothesis is that the spatial distribution of gravitating matter is a fractal at all scales up to the Hubble radius. The fractal dimension of matter distribution is assumed to be D = 2, which implies that the global gravitational redshift is the explanation of the observed linear Hubble law. In the frame of the FGF all three phenomena - the cosmic background radiation, the fractal large scale structure, and the Hubble law, - could be the consequence of a unique large scale structure evolution process of the initially homogeneous ordinary matter without nonbaryonic matter and dark energy.

description: The dissertation regards The memory on the Italian Risorgimento in “Justice and Freedom”(1929-1940) a theoretical core point in the history of the Movement, which so far has not been granted due attention. The work herewith presented is therefore aimed at filling a storiographical gap, analysing the historical events which continue to operate as traditions, raising feelings and passions and hence operating in politics, although as secondary factors. The point made is that the Justice and Freedom Movement, an antifascist political movement born
in Paris in October 1929, bases its strength on the heroic choice of the antifascism movement to fight a Second Risorgimento, connecting the fight against the regime to the battles previously fought for the justice and the freedom, an entirely isolated event in the political opposition’s panorama. The dissertation, thus, attempts to explain how and why Justice and Freedom is so tightly interconnected in its political action to the Risorgimento tradition.
The first chapter sets the cultural background of the foundation of the Justice and Freedom Movement. The centre of such foundation was Florence, where Gaetano Salvemini, along with a group of young people, would later on carry out some cultural experiences that ideally prepare the
ground for the movement’s birth.
In the second chapter are found the sites of the memory where the passage of the Risorgimento tradition between the generations takes place. The work therefore shifts from a public to a private level, concentrating on biographical paths. The choice made was for Nello Rosselli, a man very
close to the Justice and Freedom Movement but who, as opposed to his comrades-in-arms, did not chose the political way to express his ethical choice, but rather the theoretical one, becoming a Risorgimento historian.
The third chapter concentrates on the birth of the Justice and Freedom Movement in France, trying to reconstruct the cultural ties and the confrontation places and sites where the members of the Movement could interact with the French intellectual milieu, bringing back to light the propagandistic usage of the Risorgimento myth carried out by the Movement.
Lastly, the fourth chapter focuses on the cultural debate on the Risorgimento, which took place on the press organs of the Movement, pointing out and periodizing the theoretical passages and the propagandistic uses of the myth as related to the stages of the Movement and the political needs.

description: Computer representations of real numbers are necessarily discrete, with some finite resolution, discreteness, quantization, or minimum representable difference. We perform astrometric and photometric measurements on stars and co-add multiple observations of faint sources to demonstrate that essentially all of the scientific information in an optical astronomical image can be preserved or transmitted when the minimum representable difference is a factor of two finer than the root-variance of the per-pixel noise. Adopting a representation this coarse reduces bandwidth for data acquisition, transmission, or storage, or permits better use of the system dynamic range, without sacrificing any information for down-stream data analysis, including information on sources fainter than the minimum representable difference itself.

description: We present a study of Seebeck and Nernst effect in combination with magnetoresistance and Hall measurements of the Kagome superconductor CsV$_3$Sb$_5$. Sizable magneto-Seebeck signal appears once the charge density wave (CDW) order sets in below $T_{CDW}$=94 K. The Nernst signal peaks at a lower temperature $T^*$=35 K, crossing which the Hall coefficient switches sign, which we attribute to the ambipolar transport of compensated bands due to the multi-band nature of CsV$_3$Sb$_5$. Sublinear Nernst signal as a function of magnetic field, together with large anomalous Nernst effect (ANE) also emerge inside the CDW phase, despite the absence of long-range magnetic order. These findings suggest that, the transport properties are dominated by small pockets with multi-band profile, and that the unusual band topology also plays an import role in the CDW state of CsV$_3$Sb$_5$.

description: Excerpts from the report: The growth in size of cooperatives, especially major regional associations, together with the larger number of services performed by many of them has increased the importance and the complexity of the director's job. The effectiveness of board members depend upon many factors. At the request of a regional farmer cooperative and the American Institute of Cooperation, Farmer Cooperative Service undertook a project dealing with these and other problems related to qualifications, selection, and performance of boards of directors of farmer cooperatives. The purpose of this part of the study is to survey the current use and effectiveness of board committees as a tool of management and report the findings for the general guidance and assistance of all cooperatives. The report sheds light on the use of both standing and special board committees; duties, responsibilities, and authority of committees; size of committees; and frequency and length of committee meetings. It also furnishes an evaluation of special board committees designed to study and make recommendations on specific problems.

description: Discrete stability extends the classical notion of stability to random elements in discrete spaces by defining a scaling operation in a randomised way: an integer is transformed into the corresponding binomial distribution. Similarly defining the scaling operation as thinning of counting measures we characterise the corresponding discrete stability property of point processes. It is shown that these processes are exactly Cox (doubly stochastic Poisson) processes with strictly stable random intensity measures. We give spectral and LePage representations for general strictly stable random measures without assuming their independent scattering. As a consequence, spectral representations are obtained for the probability generating functional and void probabilities of discrete stable processes. An alternative cluster representation for such processes is also derived using the so-called Sibuya point processes, which constitute a new family of purely random point processes. The obtained results are then applied to explore stable random elements in discrete semigroups, where the scaling is defined by means of thinning of a point process on the basis of the semigroup. Particular examples include discrete stable vectors that generalise discrete stable random variables and the family of natural numbers with the multiplication operation, where the primes form the basis.

description: Short-distance scouting and recruiting behaviour of the Italian honeybee, Apis mellifera ligustica Spin., and the accuracy with which a recruit locates a food source indicated by successful foragers were investigated in this study. Peppermint, orange, and cinnamon oil scents were more attractive than the scents of pure honey, lavender, or anise seed oil. Sugar stimulated further visits, but when a nearby source dried up, visitors quickly went to a more distant source, though they intermittently checked the original site. The concentration of the sugar solution directly influenced recruitment. Colour and shape were most important for recruits initially locating an attractive site, but a recruit would not land and take up food unless the correct scent was present. Bees regularly investigated and visited dishes in sunlight, but seldom visited dishes in shadow. Scouts communicated direction for distances as short as 2.5 meters. When the location of the food source was changed, bees searched until they found the new location. They then continued to arrive via the original location for approximately one half-hour; thereafter they travelled directly between the hive and new location, taking directional bearings to those respective places. In absence of polarized sky-light, the route to a low source went around landmarked obstacles; in presence of polarized light, the bees flew over such obstacles. When leaving a new food location after their first two or three visits, bees hovered over it, circled, and spiralled upward in a set pattern; during later visits they returned directly to hive without such locational checks When two food sources were set up at the same distance and direction from the hive, but at different heights, two distinct groups of foragers formed, each recruited to only one of the food sources by the original scouts. These results show that recruits of the Italian honey bee, Apis m. ligustica, can locate a food source reported by others foragers with great accuracy even at short distances from the hive.

description: In February 1700, Isaac Newton needed a precise tropical year to design a new universal calendar that would supersede the Gregorian one. However, 17th-Century astronomers were uncertain of the long-term variation in the inclination of the Earth's axis and were suspicious of Ptolemy's equinox observations. As a result, they produced a wide range of tropical years. Facing this problem, Newton attempted to compute the length of the year on his own, using the ancient equinox observations reported by a famous Greek astronomer Hipparchus of Rhodes, ten in number. Though Newton had a very thin sample of data, he obtained a tropical year only a few seconds longer than the correct length. The reason lies in Newton's application of a technique similar to modern regression analysis. Newton wrote down the first of the two so-called 'normal equations' known from the ordinary least-squares (OLS) method. In that procedure, Newton seems to have been the first to employ the mean (average) value of the data set, while the other leading astronomers of the era (Tycho Brahe, Galileo, and Kepler) used the median. Fifty years after Newton, in 1750, Newton's method was rediscovered and enhanced by Tobias Mayer. Remarkably, the same regression method served with distinction in the late 1920s when the founding fathers of modern cosmology, Georges Lemaitre (1927), Edwin Hubble (1929), and Willem de Sitter (1930), employed it to derive the Hubble constant.

description: The cascade mass reconstruction approach was used for mass reconstruction of the lightest stau produced at the LHC in the cascade decay $\tilde{g} \to \tilde{b} b \to \tildeχ_{2}^{0} b b \to \tildeτ_{1} τb b \to \tildeχ_{1}^{0} ττb b $. The stau mass was reconstructed assuming that masses of gluino, bottom squark and two lightest neutralinos were reconstructed in advance. SUSY data sample sets for the SU3 model point containing 160k events each were generated which corresponded to an integrated luminosity of about $8 \rm fb^{-1}$ at 14 TeV. These events were passed through the AcerDET detector simulator, which parametrized the response of a generic LHC detector. The mass of the $\tildeτ_{1}$ was reconstructed with a precision of about 20% on average.

description: We show that for a large class of piecewise expanding maps T, the bounded p-variation observables u_0 that admits an infinite sequence of bounded p-variation observables u_i satisfying u_i(x)= u_{i+1}(Tx) -u_{i+1}(x) are constant. The method of the proof consists in to find a suitable Hilbert basis for L^2(hm), where hm is the unique absolutely continuous invariant probability of T. In terms of this basis, the action of the Perron-Frobenious and the Koopan operator on L^2(hm) can be easily understood. This result generalizes earlier results by Bamon, Kiwi, Rivera-Letelier and Urzua in the case T(x)= n x mod 1, n in N-{0,1} and Lipchitizian observables u_0.

description: The effect of non-magnetic Zn impurity on superconductivity in LaFe$_{1-y}$Zn$_y$AsO$_{1-x}$F$_x$ system is studied systematically. In the presence of Zn impurity, the superconducting transition temperature increases in the under-doped regime, remains unchanged in the optimally doped regime, and is severely suppressed in the over-doped regime. Our results suggest a switch of the symmetry of the superconducting order parameters from a $s$-wave to $s_{\pm}$ or $d$-wave states as the charge carrier doping increases in FeAs-based superconductors.

description: Sustainability transitions require changing many behaviours embedded in production and consumption systems. Simultaneously, behavioural public policy is now a significant site of research-policy translation globally. Links between behaviour and system change are underdeveloped in both fields. Systematic review of current transitions literature found ~4% of papers focused on behaviour. Two prominent perspectives on behaviour (labelled: ‘everyday’ and ‘strategic’) are critical of a focus on individuals, preferencing broader analysis. Two additional perspectives were identified - ‘automatic’ and ‘reflective’ - which highlight immediate and local influences on behaviour but underemphasise context. All four perspectives on behaviour draw on different conceptualisations, causality, methods and disciplinary foundations, and yet all have value and application to transitions. We argue that a complimentary and flexible approach to behaviour would benefit the field, considering the diversity of phases, scales and contexts of sustainability transitions. Transitions’ own behavioural perspectives could also help address behavioural public policy’s challenges.

description: A class of multidimensional integrable hierarchies connected with commutation of general (unreduced) (N+1)-dimensional vector fields containing derivative over spectral variable is considered. They are represented in the form of generating equation, as well as in the Lax-Sato form. A dressing scheme based on nonlinear vector Riemann problem is presented for this class. The hierarchies connected with Manakov-Santini equation and Dunajski system are considered as illustrative examples.

description: The objective of this dissertation is to develop and test a predictive model for the
passive kinematics of human joints based on the energy minimization principle. To
pursue this goal, the tibio-talar joint is chosen as a reference joint, for the reduced
number of bones involved and its simplicity, if compared with other sinovial joints
such as the knee or the wrist.
Starting from the knowledge of the articular surface shapes, the spatial trajectory
of passive motion is obtained as the envelop of joint configurations that
maximize the surfaces congruence. An increase in joint congruence corresponds
to an improved capability of distributing an applied load, allowing the joint to attain
a better strength with less material. Thus, joint congruence maximization is a
simple geometric way to capture the idea of joint energy minimization.
The results obtained are validated against in vitro measured trajectories. Preliminary
comparison provide strong support for the predictions of the theoretical
model.

GeV emission from Gamma Ray Bursts: a radiative fireball?

description: We study the emission observed at energies greater than 100 MeV of 11 Gamma Ray Bursts (GRBs) detected by the Fermi/Large Area Telescope (LAT) until October 2009. The GeV emission has three main properties: (i) its duration is often longer than the duration of the softer emission detected by the Gamma Burst Monitor (GBM) onboard Fermi [this confirms earlier results from the Energetic Gamma-Ray Experiment Telescope (EGRET)]; (ii) its spectrum is consistent with F(v) propto v^(-1) and does not show strong spectral evolution; (iii) for the brightest bursts, the flux detected by the LAT decays as a power law with a typical slope: t^(-1.5). We argue that the observed >0.1 GeV flux can be interpreted as afterglow emission shortly following the start of the prompt phase emission as seen at smaller frequencies. The decay slope is what expected if the fireball emission is produced in the radiative regime, i.e. all dissipated energy is radiated away. We also argue that the detectability in the GeV energy range depends on the bulk Lorentz factor Gamma of the bursts, being strongly favoured in the case of large Gamma. This implies that the fraction of bursts detected at high energies corresponds to the fraction of bursts having the largest Gamma. The radiative interpretation can help to explain why the observed X-ray and optical afterglow energetics are much smaller than the energetics emitted during the prompt phase, despite the fact that the collision with the external medium should be more efficient than internal shocks in producing the radiation we see.
