Search for heavy resonances decaying to a top quark and a bottom quark
  in the lepton+jets final state in proton-proton collisions at 13 TeV

A search is presented for narrow heavy resonances decaying to a top quark and
a bottom quark using data collected by the CMS experiment at sqrt(s) = 13 TeV
in 2016. The data set analyzed corresponds to an integrated luminosity of 35.9
inverse femtobarns. Final states that include a single lepton (e, mu), multiple
jets, and missing transverse momentum are analyzed. No evidence is found for
the production of a W' boson, and the production of right-handed W' bosons is
excluded at 95% confidence level for masses up to 3.6 TeV depending on the
scenario considered. Exclusion limits for W' bosons are also presented as a
function of their coupling strength to left- and right-handed fermions. These
limits on a W' boson decaying via a top and a bottom quark are the most
stringent published to date.Comment: Replaced with the published version. Added the journal reference and

Exploring 'What's Good about Security': politics of security during the dissolution of Yugoslavia

This is an Accepted Manuscript of an article published in the Journal of Balkan and Near Eastern Studies on 01 May 2014, available online: http://www.tandfonline.com/10.1080/19448953.2014.910390In the last decade, students of Critical Security Studies (CSS) have been increasingly studying and understanding the concept of security in negative terms. The way they choose to analyse security instils a one-sided understanding, which revolves around totalizing the material and ideational power of the state. This paper aims to discuss how students of CSS can avoid essentializing the meaning of security by extending its analytical scope beyond security professionalism and state-centrism. It will be argued that it is possible to inquire 'what is good about security' by examining the experiences of the most victimized through a study of the pluralism of politics of security. The argument will be illustrated through a discussion of ideas and practices of the Yugoslav anti-war feminist movement between 1989 and 1994
Weak ferromagnetism and short range polar order in NaMnF3 thin films

This paper was published in the journal, Applied Physics Letters and the definitive version is available at: http://dx.doi.org/10.1063/1.4977421 with supplementary information at: ftp://ftp.aip.org/epaps/appl_phys_lett/E-APPLAB-110-018709The orthorhombically distorted perovskite NaMnF3 has been predicted to become ferroelectric if an a = c distortion of the bulk Pnma structure is imposed. In order to test this prediction, NaMnF3 thin films were grown on SrTiO3 (001) single crystal substrates via molecular beam epitaxy. The best films were smooth and single phase with four different twin domains. In-plane magnetization measurements revealed the presence of antiferromagnetic ordering with weak ferromagnetism below the Néel temperature TN = 66 K. For the dielectric studies, NaMnF3 films were grown on a 30 nm SrRuO3 (001) layer used as a bottom electrode grown via pulsed laser deposition. The complex permittivity as a function of frequency indicated a strong Debye-like relaxation contribution characterized by a distribution of relaxation times. A power-law divergence of the characteristic relaxation time revealed an order-disorder phase transition at 8 K. The slow relaxation dynamics indicated the formation of super-dipoles (superparaelectric moments) that extend over several unit cells, similar to polar nanoregions of relaxor ferroelectrics
Massive star evolution :
                    nucleosynthesis and nuclear reaction rate uncertainties

We present a nucleosynthesis calculation of a 25 M-circle dot star of solar composition that includes all relevant isotopes up to polonium. We follow the stellar evolution from hydrogen burning till iron core collapse and simulate the explosion using a 'piston' approach. We discuss the influence of two key nuclear reaction rates, C-12(alpha, gamma)O-16 and Ne-22(alpha, n)Mg-25, on stellar evolution and nucleosynthesis. The former significantly influences the resulting core sizes (iron, silicon, oxygen) and the overall presupernova structure of the star. It thus has significant consequences for the supernova explosion itself and the compact remnant formed. The later rate considerably affects the s-process in massive stars and we demonstrate the changes that different currently suggested values for this rate cause. (C) 2002 Elsevier Science B.V.

From saturated to unsaturated conditions and vice versa

Representing transitions between saturated and unsaturated conditions, during drying, wetting and loading paths, is a necessary step for a consistent unification between saturated and unsaturated soil mechanics. Transitions from saturated to unsaturated conditions during drying will occur at a nonzero air-entry value of suction, whereas transitions from unsaturated to saturated conditions during wetting or loading will occur at a lower nonzero air-exclusion value of suction. Air-entry and air-exclusion values of suction for a given soil will differ (representing hysteresis in the retention behaviour) and both are affected by changes in the dry density of the soil or by the occurrence of plastic volumetric strains. The paper demonstrates, through model simulations and comparison with experimental data from the literature (covering drying, wetting and loading tests), that the Glasgow Coupled Model (GCM), a coupled elasto-plastic constitutive model covering both mechanical and retention behaviour, represents transitions between unsaturated and saturated behaviour in a consistent fashion. Key aspects of the GCM are the use of Bishop’s stress tensor for mechanical behaviour, the additional influence of degree of saturation on mechanical yielding, inclusion of hysteresis in the retention behaviour, and the role of plastic volumetric strains (and not total volumetric strains) in the description of the water retention response. The success of the GCM in representing consistently transitions between saturated and unsaturated conditions, together with subsequent mechanical and retention responses, demonstrates the potential of this coupled constitutive model for numerical modelling of boundary value problems involving saturated and unsaturated conditions.Peer ReviewedPostprint (published version
Response to "Comment on 'Indications of energetic consequences of decoherence at short times for scattering from open quantum systems'" [AIP Advances 1, 049101 (2011)]

The Comment by Mayers and Reiter criticizes our work on two counts. Firstly, it is claimed that the quantum decoherence effects that we report in consequence of our experimental analysis of neutron Compton scattering from H in gaseous H2 are not, as we maintain, outside the framework of conventional neutron scattering theory. Secondly, it is claimed that we did not really observe such effects, owing to a faulty analysis of the experimental data, which are claimed to be in agreement with conventional theory. We focus in this response on the critical issue of the reliability of our experimental results and analysis. Using the same standard Vesuvio instrument programs used by Mayers et al., we show that, if the experimental results for H in gaseous H2 are in agreement with conventional theory, then those for D in gaseous D2 obtained in the same way cannot be, and vice-versa. We expose a flaw in the calibration methodology used by Mayers et al. that leads to the present disagreement over the behaviour of H, namely the ad hoc adjustment of the measured H peak positions in TOF during the calibration of Vesuvio so that agreement is obtained with the expectation of conventional theory. We briefly address the question of the necessity to apply the theory of open quantum systems.Full Tex

Measurement Properties of Tools Used to Assess Depression in Adults with and without Autism Spectrum Conditions: A Systematic Review

Depression is the most commonly experienced mental health condition in adults with Autism Spectrum Conditions (ASC). However, it is unclear what tools are currently being used to assess depression in ASC, or whether tools need to be adapted for this group. This systematic review therefore aimed to identify tools used to assess depression in adults with and without ASC, and then evaluate these tools for their appropriateness and measurement properties. Medline, PsychINFO and Web of Knowledge were searched for studies of depression in: a) adults with ASC, without co-morbid intellectual disability; and b) adults from the general population without co-morbid conditions. Articles examining the measurement properties of these tools were then searched for using a methodological filter in PubMed, and the quality of the evidence was evaluated using the COSMIN checklist. Twelve articles were identified which utilised three tools to assess depression in adults with ASC, but only one article which assessed the measurement properties of one of these tools was identified and thus evaluated. Sixty-five articles were identified which utilised five tools to assess depression in general population adults, and 14 articles had assessed the measurement properties of these tools. Overall, two tools were found to be robust in their measurement properties in the general population – the Beck Depression Inventory (BDI-II), and the Patient Health Questionnaire (PHQ-9). Crucially only one study was identified from the COSMIN search, which showed weak evidence in support of the measurement properties of the BDI-II in an ASC sample. Implications for effective measurement of depression in ASC are discussed
Compliance aware business process design

Historically, business process design has been driven by business objectives, specifically process improvement. However this cannot come at the price of control objectives which stem from various legislative, standard and business partnership sources. Ensuring the compliance to regulations and industrial standards is an increasingly important issue in the design of business processes. In this paper, we advocate that control objectives should be addressed at an early stage, i.e., design time, so as to minimize the problems of runtime compliance checking and consequent violations and penalties. To this aim, we propose supporting mechanisms for business process designers. This paper specifically presents a support method which allows the process designer to quantitatively measure the compliance degree of a given process model against a set of control objectives. This will allow process designers to comparatively assess the compliance degree of their design as well as be better informed on the cost of non-compliance
Computing sharp 2-factors in claw-free graphs.\ud

In a previous paper we obtained an upper bound for the minimum number of components of a 2-factor in a claw-free graph. This bound is sharp in the sense that there exist infinitely many claw-free graphs for which the bound is tight. In this paper we extend these results by presenting a polynomial algorithm that constructs a 2-factor of a claw-free graph with minimum degree at least four whose number of components meets this bound. As a byproduct we show that the problem of obtaining a minimum 2-factor (if it exists) is polynomially solvable for a subclass of claw-free graphs. As another byproduct we give a short constructive proof for a result of Ryjáček, Saito and Schelp.\ud

NNLO QCD corrections to event orientation in $e^+e^-$ annihilation

We present a new implementation of the NNLO QCD corrections to three-jet final states and related event-shape observables in electron–positron annihilation. Our implementation is based on the antenna subtraction method, and is performed in the NNLOjet framework. The calculation improves upon earlier results by taking into account the full kinematical information on the initial state momenta, thereby allowing the event orientation to be computed to NNLO accuracy. We find the event-orientation distributions at LEP and SLC to be very robust under higher order QCD corrections
Friendly fire : engineering a fort wall in the Iron Age.

There is widespread evidence that the walls of Iron Age forts across Europe were set on fire, causing partial melting of the stonework followed by either recrystallization or glass formation on cooling – a process termed “vitrification”. The motivation for fort wall firing has remained speculative since its first description in 1777. Since the suggestion of MacKie (1969) that fort vitrification might destabilize fort walls, the debate as to motives has focused on combative or destructive intentions. Here, a multidisciplinary analysis of experimental fort wall samples shows that in fact vitrification results in strengthening, not weakening. The strengthening involves diffusive and viscous sintering of material aggregates and size-dependent heat transfer. These new results support a long-since-dismissed idea that Iron Age fort walls were intentionally set ablaze in order to fortify the walls
Inter-rater reliability for measurement of passive physiological movements in lower extremity joints is generally low: a systematic review.

                  87996.pdf (publisher's version ) (Open Access)QUESTION: What is the inter-rater reliability for measurements of passive physiological or accessory movements in lower extremity joints? DESIGN: Systematic review of studies of inter-rater reliability. PARTICIPANTS: Individuals with and without lower extremity disorders. OUTCOME MEASURES: Range of motion and end-feel using methods feasible in daily practice. RESULTS: 17 studies were included of which 5 demonstrated acceptable inter-rater reliability. Reliability of measurements of physiological range of motion ranged from Kappa -0.02 for measuring knee extension using a goniometer to ICC 0.97 for measuring knee flexion using vision. Measuring range of knee flexion consistently yielded acceptable reliability using either vision or instruments. Measurements of end-feel were unreliable for all hip and knee movements. Two studies satisfied all criteria for internal validity while reporting acceptable reliability for measuring physiological range of knee flexion and extension. Overall,however, methodological quality of included studies was poor. CONCLUSION: Inter-rater reliability of measurement of passive movements in lower extremity joints is generally low. We provide specific recommendations for the conduct and reporting of future research. Awaiting new evidence, clinicians should be cautious when relying on results from measurements of passive movements in joints for making decisions about patients with lower extremity disorders
Beurling-Landau's density on compact manifolds

Given a compact Riemannian manifold $M$, we consider the subspace of $L^2(M)$ generated by the eigenfunctions of the Laplacian of
eigenvalue less than $L\geq1$. This space behaves like a space of polynomials and we have an analogy with the Paley-Wiener spaces. We
study the interpolating and Marcinkiewicz-Zygmund (M-Z) families and provide necessary conditions for sampling and interpolation in terms
of the Beurling-Landau densities. As an application, we prove the equidistribution of the Fekete arrays on some compact manifolds
Seiberg duality versus hidden local symmetry.

It is widely believed that the emergent magnetic gauge symmetry of SQCD is analogous to a hidden local symmetry (HLS). We explore this idea in detail, deriving the entire (spontaneously broken) magnetic theory by applying the HLS formalism to spontaneously broken SU(N) SQCD. We deduce the Kähler potential in the HLS description, and show that gauge and flavour symmetry are smoothly restored along certain scaling directions in moduli space. We propose that it is these symmetry restoring directions, associated with the R-symmetry of the theory, that allow full Seiberg duality. Reconsidering the origin of the magnetic gauge bosons as the ρ-mesons of the electric theory, colour-flavour locking allows a simple determination of the parameter a. Its value continuously interpolates between a = 2 on the baryonic branch of moduli space — corresponding to “vector meson dominance” — and a = 1 on the mesonic branch. Both limiting values are consistent with previous results in the literature. The HLS formalism is further applied to SO and Sp groups, where the usual Seiberg duals are recovered, as well as adjoint SQCD. Finally we discuss some possible future applications, including (naturally) the unitarisation of composite W scattering, blended Higgs/technicolour models, real world QCD and non-supersymmetric dualities
WASP-35b, WASP-48b, and HAT-P-30b/WASP-51b : two new planets and an independent discovery of a hat planet

We report the detection of WASP-35b, a planet transiting a metal-poor ([Fe/H] = –0.15) star in the Southern hemisphere, WASP-48b, an inflated planet which may have spun-up its slightly evolved host star of 1.75 R ☉ in the Northern hemisphere, and the independent discovery of HAT-P-30b/WASP-51b, a new planet in the Northern hemisphere. Using WASP, RISE, Faulkes Telescope South, and TRAPPIST photometry, with CORALIE, SOPHIE, and NOT spectroscopy, we determine that WASP-35b has a mass of 0.72 ± 0.06 MJ and radius of 1.32 ± 0.05RJ , and orbits with a period of 3.16 days, WASP-48b has a mass of 0.98 ± 0.09 MJ , radius of 1.67 ± 0.10 RJ , and orbits in 2.14 days, while HAT-P-30b/WASP-51b, with an orbital period of 2.81 days, is found to have a mass of 0.76 ± 0.05 MJ and radius of 1.42 ± 0.03 RJ , agreeing with values of 0.71 ± 0.03 MJ and 1.34 ± 0.07 RJ reported for HAT-P-30b.Publisher PDFPeer reviewe
Exact Solutions for Nonlocal Nonlinear Field Equations in Cosmology

A method for the search of exact solutions for equation of a nonlocal scalar
field in a non-flat metric is considered. In the Friedmann-Robertson-Walker
metric the proposed method can be used in the case of an arbitrary potential,
with the exception of linear and quadratic potentials, and allows to get in
quadratures solutions, which depend on two arbitrary parameters. Exact
solutions have been found for an arbitrary cubic potential, which consideration
is motivated by the string field theory, as well as for exponential,
logarithmic and power potentials. It has been shown that one can add the
k-essence field to the model to get exact solutions for all Einstein equations.Comment: 14 pages, v2: Section 5 added, accepted for publication in Theor.

A Spectropolarimetric Test of the Structure of the Intrinsic Absorbers
  in the Quasar HS1603+3820

We report the results of a spectropolarimetric observation of the C IV
mini-BAL in the quasar HS1603+3820. The observations were carried out with the
FOCAS instrument on the Subaru telescope and yielded an extremely high
polarization sensitivity of 0.1%, at a resolving power of 1500. HS1603+3820 has
been the target of a high-resolution spectroscopic monitoring campaign for more
than four years, aimed at studying its highly variable C IV mini-BAL profile.
Using the monitoring observations, in an earlier paper we were able to narrow
down the causes of the variability to the following two scenarios: (1)
scattering material of variable optical depth redirecting photons around the
absorber, and (2) a variable, highly-ionized screen between the continuum
source and the absorber which modulates the UV continuum incident on the
absorber. The observations presented here provide a crucial test of the
scattering scenario and lead us to disfavor it because (a) the polarization
level is very small (p~0.6%) throughout the spectrum, and (b) the polarization
level does not increase across the mini-BAL trough. Thus, the variable screen
scenario emerges as our favored explanation of the C IV mini-BAL variability.
Our conclusion is bolstered by recent X-ray observations of nearby mini-BAL
quasars, which show a rapidly variable soft X-ray continuum that appears to be
the result of transmission through an ionized absorber of variable ionization
parameter and optical depth.Comment: To appear in the Astrophysical Journal, vol. 719, August 201
An approximate version of Sumner's universal tournament conjecture

Sumner's universal tournament conjecture states that any tournament on $2n-2$
vertices contains a copy of any directed tree on $n$ vertices. We prove an
asymptotic version of this conjecture, namely that any tournament on
$(2+o(1))n$ vertices contains a copy of any directed tree on $n$ vertices. In
addition, we prove an asymptotically best possible result for trees of bounded
degree, namely that for any fixed $\Delta$, any tournament on $(1+o(1))n$
vertices contains a copy of any directed tree on $n$ vertices with maximum
degree at most $\Delta$.Comment: 36 page
