Search for physics beyond the standard model in events with two leptons, jets, and missing transverse momentum in pp collisions at sqrt(s) = 8 TeV

A search is presented for physics beyond the standard model in final states with two opposite-sign same-flavor leptons, jets, and missing transverse momentum. The data sample corresponds to an integrated luminosity of 19.4 inverse femtobarns of proton-proton collisions at sqrt(s) = 8 TeV collected with the CMS detector at the CERN LHC in 2012. The analysis focuses on searches for a kinematic edge in the invariant mass distribution of the opposite-sign same- flavor lepton pair and for final states with an on-shell Z boson. The observations are consistent with expectations from standard model processes and are interpreted in terms of upper limits on the production of supersymmetric particles
A Cross-national analysis of the relations between school choice and effectiveness differences between private-independent and public schools

We apply propensity score matching to the estimation of the disparity in school effectiveness between the privately owned, privately funded school sector and the public one in a sample of 25 countries in Europe, America and Asia. This technique allows us to distinguish between school choice and school effectiveness processes and thus, to account for selectivity induced variation in school effectiveness. We find two broad patterns of private independent school choice: the choice as a social class reproduction choice; and the choice of an outsider’s for a good-equipped school. As regards school effectiveness, our results show that, after controlling for selectivity and school choice processes, the initial higher reading scores of students in private-independent schools become comparable to those public schools students in a majority of countries. However, in a few countries average reading scores remain higher in the private independent sector even after introducing controls for school choice induced selectivity. The opposite pattern, namely of higher average reading scores in the public sector has also been found in four countries.
Consumer credit in an era of financial liberalisation: An overreaction to repressed demand?

In this paper we empirically analyse the factors which determined consumer credit in Greece in the period before and after the financial liberalisation, while accounting for significant changes in structure due to the lifting of credit restrictions and the subsequent impressive boom of consumer loans. We use multivariate cointegration techniques to estimate a vector error correction model (VECM) and identify separate demand and supply relationships for consumer loans. We introduce demand and supply-related shifts in parameters through the inclusion of appropriate dummy variables and trends in the long-run relationships. We partly deviate from the typical Johansen procedure and estimate the model in two steps. We find that the theoretical exclusion and coefficient-size restrictions on the demand and supply cointegrating vectors are valid. Our results are consistent with the operation of a bank lending channel in Greece. We also find that the supply side was mostly responsible for the acceleration of consumer loan growth following credit liberalisation.
Generalized �Fixed-T Panel Unit Root Tests Allowing for Structural Breaks

In this paper we suggest panel data unit root tests which allow for a structural breaks in the individual
effects or linear trends of panel data models. This is done under the assumption that the disturbance
terms of the panel are heterogeneous and serially correlated. The limiting distributions of the suggested
test statistics are derived under the assumption that the time-dimension of the panel (T) is �fixed, while
the cross-section (N) grows large. Thus, they are appropriate for short panels, where T is small. The
tests consider the cases of a known and unknown date break. For the latter case, the paper gives the
analytic form of the distribution of the test statistics. Monte Carlo evidence suggest that our tests have
size which is very close to its nominal level and satisfactory power in small-T panels. This is true even
for cases where the degree of serial correlation is large and negative, where single time series unit root
tests are found to be critically oversized.
Análise do potencial de ação composto do nervo auditivo evocado eletricamente em crianças usuárias de implante coclear bilateral

Introdução: o implante coclear tem a capacidade de medir o potencial de ação composto eletricamente evocado do nervo auditivo (ECAP). Para esta verificação utiliza-se uma medida chamada telemetria de respostas neurais.  OBJETIVO: Analisar o potencial de ação composto evocado eletricamente, por meio da neurotelemetria de respostas neurais, em crianças usuárias de implante coclear bilateral.  MÉTODO: Trata-se de um estudo analítico, prospectivo, de coorte histórica longitudinal. Foram recrutadas seis crianças, com idades entre de 1-4 anos, usuárias de implante coclear bilateral. Estas crianças foram avaliadas em cinco momentos durante o primeiro ano de uso do implante coclear.  RESULTADOS: Houve diferença significativa no tempo de acompanhamento (p = 0,0082) e posição do eletrodo (p = 0,0019) na medida de T-NRT. Houve diferença significativa na interação entre tempo de acompanhamento e posição do eletrodo (p = 0,0143) na medida da amplitude das ondas N1-P1 entre os três eletrodos a cada tempo de acompanhamento.  CONCLUSÃO: A mensuração do ECAP por meio da NRT nas crianças com implante coclear bilateral durante o primeiro ano de acompanhamento foi uma medida importante para apresentar o desenvolvimento bilateral da via auditiva periférica de forma sincronizada nesta população estudada.Introduction: the cochlear implant device has the capacity to measure the electrically evoked compound action potential of the auditory nerve. The neural response telemetry is used in order to measure the electrically evoked compound action potential of the auditory nerve.  OBJECTIVE: To analyze the electrically evoked compound action potential, through the neural response telemetry, in children with bilateral cochlear implants.  METHODS: This is an analytical, prospective, longitudinal, historical cohort study. Six children, aged 1-4 years, with bilateral cochlear implant were assessed at five different intervals during their first year of cochlear implant use.  RESULTS: There were significant differences in follow-up time (p = 0.0082) and electrode position (p = 0.0019) in the T-NRT measure. There was a significant difference in the interaction between time of follow-up and electrode position (p = 0.0143) when measuring the N1-P1 wave amplitude between the three electrodes at each time of follow-up.  CONCLUSION: The electrically evoked compound action potential measurement using neural response telemetry in children with bilateral cochlear implants during the first year of follow-up was effective in demonstrating the synchronized bilateral development of the peripheral auditory pathways in the studied population
James Fitzpiers Fitzgerald, Captain Thomas Lee, and the Problem of “Secret Traitors”: Conflicted Loyalties During the Nine Years’ War, 1594-1603

Existing evidence pertaining to Ireland’s Nine Years’ War (1594-1603) strongly lends itself to the impression that the majority of Old English Palesmen, at least those of higher social status, chose to support the English crown during this conflict rather than their co-religionist Gaelic Irish countrymen. Loyalties, however, were anything but straightforward and could depend on any number of cultural values, social concerns, and economic incentives. Nevertheless, James Fitzpiers Fitzgerald, a ‘Bastard Geraldine’ who served as sheriff of Kildare, seemed to have been driven by a genuine sense of duty to the English crown and establishment. With the outbreak of hostilities in the 1590s, Fitzpiers proved to be a devout crown servitor, risking life and limb to confront the English queen’s Irish enemies. But, in late 1598 he suddenly, and somewhat inexplicably, threw his lot in with Irish Confederacy, defying the government he had once championed. During the ensuing investigation, the Dublin administration accumulated much damning evidence against Fitzpiers, including a patriotic plea from rebel leader Hugh O’Neill which urged Fitzpiers to defend his Irish homeland from the oppressions of English Protestant rule. Yet, at the very same time, a counter case was made by Fitzpiers’ controversial English friend, Captain Thomas Lee, which argued that Fitzpiers’ actions were more loyal than anyone could have imagined. Through an examination of Fitzpiers’ perplexing case, this paper will explore the complicated nature of allegiances in 1590s Ireland and how loyalties were not always what they seemed
On Lundh's percolation diffusion

A collection of spherical obstacles in the unit ball in Euclidean space is said to be avoidable for Brownian motion if there is a positive probability that Brownian motion diffusing from some point in the ball will avoid all the obstacles and reach the boundary of the ball. The centres of the spherical obstacles are generated according to a Poisson point process while the radius of an obstacle is a deterministic function. If avoidable configurations are generated with positive probability, Lundh calls this percolation diffusion. An integral condition for percolation diffusion is derived in terms of the intensity of the point process and the function that determines the radii of the obstacles
A new behavioural apparatus to reduce animal numbers in multiple types of spontaneous object recognition paradigms in rats.

Standard object recognition procedures assess animals’ memory through their spontaneous exploration of novel objects or novel configurations of objects with other aspects of their environment. Such tasks are widely used in memory research, but also in pharmaceutical companies screening new drug treatments. However, behaviour in these tasks may be driven by influences other than novelty such as stress from handling which can subsequently influence performance. This extra-experimental variance means that large numbers of animals are required to maintain power. In addition, accumulation of data is time consuming as animals typically perform only one trial per day. The present study aimed to explore how effectively recognition memory could be tested with a new continual trials apparatus which allows for multiple trials within a session and reduced handling stress through combining features of delayed nonmatching-to-sample and spontaneous object recognition tasks. In this apparatus Lister hooded rats displayed performance significantly above chance levels in object recognition tasks (Experiments 1 and 2) and in tasks of object-location (Experiment 3) and object-in-context memory (Experiment 4) with data from only five animals or fewer per experimental group. The findings indicated that the results were comparable to those of previous reports in the literature and maintained statistical power whilst using less than a third of the number of animals typically used in spontaneous recognition paradigms. Overall, the results highlight the potential benefit of the continual trials apparatus to reduce the number of animals used in recognition memory tasks
LDL-cholesterol concentrations: a genome-wide association study.

BACKGROUND: LDL cholesterol has a causal role in the development of cardiovascular disease. Improved understanding of the biological mechanisms that underlie the metabolism and regulation of LDL cholesterol might help to identify novel therapeutic targets. We therefore did a genome-wide association study of LDL-cholesterol concentrations. METHODS: We used genome-wide association data from up to 11,685 participants with measures of circulating LDL-cholesterol concentrations across five studies, including data for 293 461 autosomal single nucleotide polymorphisms (SNPs) with a minor allele frequency of 5% or more that passed our quality control criteria. We also used data from a second genome-wide array in up to 4337 participants from three of these five studies, with data for 290,140 SNPs. We did replication studies in two independent populations consisting of up to 4979 participants. Statistical approaches, including meta-analysis and linkage disequilibrium plots, were used to refine association signals; we analysed pooled data from all seven populations to determine the effect of each SNP on variations in circulating LDL-cholesterol concentrations. FINDINGS: In our initial scan, we found two SNPs (rs599839 [p=1.7x10(-15)] and rs4970834 [p=3.0x10(-11)]) that showed genome-wide statistical association with LDL cholesterol at chromosomal locus 1p13.3. The second genome screen found a third statistically associated SNP at the same locus (rs646776 [p=4.3x10(-9)]). Meta-analysis of data from all studies showed an association of SNPs rs599839 (combined p=1.2x10(-33)) and rs646776 (p=4.8x10(-20)) with LDL-cholesterol concentrations. SNPs rs599839 and rs646776 both explained around 1% of the variation in circulating LDL-cholesterol concentrations and were associated with about 15% of an SD change in LDL cholesterol per allele, assuming an SD of 1 mmol/L. INTERPRETATION: We found evidence for a novel locus for LDL cholesterol on chromosome 1p13.3. These results potentially provide insight into the biological mechanisms that underlie the regulation of LDL cholesterol and might help in the discovery of novel therapeutic targets for cardiovascular disease
Light curves and colours of the faint Uranian irregular satellites
  Sycorax, Prospero, Stephano, Setebos and Trinculo

After the work of Gladman et al. (1998), it is now assessed that many
irregular satellites are orbiting around Uranus. Despite many studies have been
performed in past years, very few is know for the light-curves of these objects
and inconsistencies are present between colours derived by different authors.
This situation motivated our effort to improve both the knowledge of colours
and light curves. We present and discuss time series observations of Sycorax,
Prospero, Stephano, Setebos and Trinculo, five faint irregular satellites of
Uranus, carried out at VLT, ESO Paranal (Chile) in the nights between 29 and 30
July, 2005 and 25 and 30 November, 2005. We derive light curves for Sycorax and
Prospero and colours for all of these these bodies. For Sycorax we obtain
colours B-V =0.839 +/- 0.014, V-R = 0.531 +/- 0.005 and a light curve which is
suggestive of a periodical variation with period about 3.6 hours and amplitude
about 0.067 +/- 0.004 mag. The periods and colours we derive for Sycorax are in
agreement with our previous determination in 1999 using NTT. We derive also a
light-curve for Prospero which suggests an amplitude of about 0.2 mag and a
periodicity of about 4 hours. However, the sparseness of our data, prevents a
more precise characterization of the light-curves, and we can not determine
wether they are one-peaked or two-peaked. Hence, these periods and amplitudes
have to be considered preliminary estimates. As for Setebos, Stephano and
Trinculo the present data do not allow to derive any unambiguous periodicity,
despite Setebos displays a significant variability with amplitude about as
large as that of Prospero. Colours for Prospero, Setebos, Stephano and Trinculo
are in marginal agreement with the literature.Comment: Submitted to A&A 13 Dec 2006, Accepted 17 Apr 2007. 18 pages, 8

Effective Pruefer Angles and Relative Oscillation Criteria

We present a streamlined approach to relative oscillation criteria based on
effective Pruefer angles adapted to the use at the edges of the essential
spectrum.
  Based on this we provided a new scale of oscillation criteria for general
Sturm-Liouville operators which answer the question whether a perturbation
inserts a finite or an infinite number of eigenvalues into an essential
spectral gap. As a special case we recover the Gesztesy-Uenal criterion (which
works below the spectrum and contains classical criteria by Kneser, Hartman,
Hille, and Weber) and the well-known results by Rofe-Beketov including the
extensions by Schmidt.Comment: 22 page
On Residual Finiteness of Monoids, their Schutzenberger Groups and
  Associated Actions

In this paper we discuss connections between the following properties: (RFM)
residual finiteness of a monoid M; (RFSG) residual finiteness of Schutzenberger
groups of M; and (RFRL) residual finiteness of the natural actions of M on its
Green's R- and L-classes. The general question is whether (RFM) implies (RFSG)
and/or (RFRL), and vice versa. We consider these questions in all the possible
combinations of the following situations: M is an arbitrary monoid; M is an
arbitrary regular monoid; every J-class of M has finitely many R- and
L-classes; M has finitely many left and right ideals. In each case we obtain
complete answers.Comment: 27 pages, 3 figures, revised according to referee's comments, to

(No) dynamical constraints on the mass of the black hole in two ULXs

We present the preliminary results of two Gemini campaigns to constrain the
mass of the black hole in an ultraluminous X-ray source (ULX) via optical
spectroscopy. Pilot studies of the optical counterparts of a number of ULXs
revealed two candidates for further detailed study, based on the presence of a
broad He II 4686 Angstrom emission line. A sequence of 10 long-slit spectra
were obtained for each object, and the velocity shift of the ULX counterpart
measured. Although radial velocity variations are observed, they are not
sinusoidal, and no mass function is obtained. However, the broad He II line is
highly variable on timescales shorter than a day. If associated with the
reprocessing of X-rays in the accretion disc, its breadth implies that the disc
must be close to face-on.Comment: 5 pages, 4 figures. Accepted for publication in Astronomische

Investigating transition state resonances in the time domain by means of
  Bohmian mechanics: The F+HD reaction

In this work, we investigate the existence of transition state resonances on
atom-diatom reactive collisions from a time-dependent perspective, stressing
the role of quantum trajectories as a tool to analyze this phenomenon. As it is
shown, when one focusses on the quantum probability current density, new
dynamical information about the reactive process can be extracted. In order to
detect the effects of the different rotational populations and their
dynamics/coherences, we have considered a reduced two-dimensional dynamics
obtained from the evolution of a full three-dimensional quantum time-dependent
wave packet associated with a particular angle. This reduction procedure
provides us with information about the entanglement between the radial degrees
of freedom (r,R) and the angular one (\gamma), which can be considered as
describing an environment. The combined approach here proposed has been applied
to study the F+HD reaction, for which the FH+D product channel exhibits a
resonance-mediated dynamics.Comment: 12 pages, 9 figure
Matter-Antimatter Asymmetry Generated by Loop Quantum Gravity

We show that Loop Quantum Gravity provides new mechanisms through which
observed matter-antimatter asymmetry in the Universe can naturally arise at
temperatures less than GUT scale. This is enabled through the introduction of a
new length scale ${\cal L}$, much greater than Planck length ($l_P$), to obtain
semi-classical weave states in the theory. This scale which depends on the
momentum of the particle modifies the dispersion relation for different
helicities of fermions and leads to lepton asymmetry.Comment: To appear in Phys. Lett. B. Minor changes in presentation. References

The spectrum of D_s mesons from lattice QCD

The spectrum of orbitally excited $D_s$ mesons is computed in the continuum
limit of quenched lattice QCD. The results are consistent with the
interpretation that the narrow resonance in the $D_s \pi^0$ channel discovered
by the BABAR Collaboration is a $J^P=0^+$ $c\bar{s}$ meson. Furthermore, within
statistical errors, the $1^+-1^-$ and the $0^+-0^-$ mass splittings are equal,
in agreement with the chiral multiplet structure predicted by heavy hadron
chiral effective theory. On our coarsest lattice we present results from the
first study of orbitally excited $D_s$ mesons with two flavors of dynamical
quarks, with mass slightly larger than the strange quark mass. These results
are consistent with the quenched data.Comment: 8 pages, 2 figure
A precise determination of the decay constant of the D(s)-meson in
  quenched QCD

We present a precise determination of the leptonic decay constant F_D(s) of
the D(s)-meson in quenched lattice QCD. This work is particularly focused on
the analysis and discussion of all sources of systematic errors. We simulate
directly at the physical quark masses for five different lattice spacings
between 0.1fm and 0.03fm using O(a)-improvement. The finest lattice is still
work in progress. After taking the continuum limit and setting the scale with
the Kaon decay constant F_K=160MeV we arrive at a value of F_D(s)=252(9)MeV.
Setting the scale with the nucleon mass instead leads to a decrease of about
20MeV of F_D(s).Comment: 3 pages, Lattice2003(heavy
Classification of dark energy models in the (w_0,w_a) plane

We classify dark energy models in a plane of observables that correspond to
the common parameterization of a non-constant equation of state, w(a)=w_0 +
w_a(1-a), where $a$ is the scale factor of the universe. The models fall into
four classes and only two of these classes have a region of overlap in the
observable plane. We perform a joint analysis of all Type Ia supernova (SNIa)
data compiled by the High-Z SN Search Team (HZT) and the Supernova Legacy
Survey (SNLS) and find that no class of models is excluded by current SNIa
data. However, an analysis of large scale structure, Ly$\alpha$ forest and bias
constraints from SDSS, the Gold SNIa data and WMAP data indicates that
non-phantom barotropic models with a a positive sound speed are excluded at the
95% C.L.Comment: 11 pages, 3 figures. Classification generalized to include models for
  which the equation of state crosses the phantom divide line. Published

Probing quantum and classical turbulence analogy through global
  bifurcations in a von K\'arm\'an liquid Helium experiment

We report measurements of the dissipation in the Superfluid Helium high
REynold number von Karman flow (SHREK) experiment for different forcing
conditions, through a regime of global hysteretic bifurcation. Our
macroscopical measurements indicate no noticeable difference between the
classical fluid and the superfluid regimes, thereby providing evidence of the
same dissipative anomaly and response to asymmetry in fluid and superfluid
regime. %In the latter case, A detailed study of the variations of the
hysteretic cycle with Reynolds number supports the idea that (i) the stability
of the bifurcated states of classical turbulence in this closed flow is partly
governed by the dissipative scales and (ii) the normal and the superfluid
component at these temperatures (1.6K) are locked down to the dissipative
length scale.Comment: 5 pages, 5 figure
