Searches for Supersymmetry using the MT2 Variable in Hadronic Events Produced in $pp$ Collisions at 8 TeV

Searches for supersymmetry (SUSY) are performed using a sample of hadronic events produced in 8 TeV pp collisions at the CERN LHC. The searches are based on the MT2 variable, which is a measure of the transverse momentum imbalance in an event. The data were collected with the CMS detector and correspond to an integrated luminosity of 19.5 fb−1. Two related searches are performed. The first is an inclusive search based on signal regions defined by the value of the MT2 variable, the hadronic energy in the event, the jet multiplicity, and the number of jets identified as originating from bottom quarks. The second is a search for a mass peak corresponding to a Higgs boson decaying to a bottom quark-antiquark pair, where the Higgs boson is produced as a decay product of a SUSY particle. For both searches, the principal backgrounds are evaluated with data control samples. No significant excess over the expected number of background events is observed, and exclusion limits on various SUSY models are derived
Measurement of the forward-backward asymmetry in $Z/\gamma^{\ast} \rightarrow \mu^{+}\mu^{-}$ decays and determination of the effective weak mixing angle

The forward-backward charge asymmetry for the process $q\bar{q} \rightarrow Z/\gamma^{\ast} \rightarrow \mu^{+}\mu^{-}$ is measured as a function of the invariant mass of the dimuon system. Measurements are performed using proton proton collision data collected with the LHCb detector at $\sqrt{s} = 7$ and 8\tev, corresponding to integrated luminosities of $1$fb$^{-1}$ and $2$fb$^{-1}$ respectively. Within the Standard Model the results constrain the effective electroweak mixing angle to be $$sin^{2}\theta_{W}^{eff} = 0.23142 \pm 0.00073 \pm 0.00052 \pm 0.00056 $$ where the first uncertainty is statistical, the second systematic and the third theoretical. This result is in agreement with the current world average, and is one of the most precise determinations at hadron colliders to date
The extended thermodynamic properties of Taub–NUT/Bolt–AdS spaces

We investigate the extended thermodynamic properties of higher-dimensional Taub–NUT/Bolt–AdS spaces where a cosmological constant is treated as a pressure. We find a general form for thermodynamic volumes of Taub–NUT/Bolt–AdS black holes for arbitrary dimensions. Interestingly, it is found that the Taub–NUT–AdS metric has a thermodynamically stable range when the total number of dimensions is a multiple of 4 (4, 8, 12, …). We also explore their phase structure and find the first order phase transition holds for higher-dimensional cases
Non-equilibrium dynamics and AdS 4 Robinson-Trautman

The Robinson-Trautman space-times provide solutions of Einstein’s equations with negative cosmological constant, which settle to AdS 4 Schwarzschild black hole at late times. Via gauge/gravity duality they should describe a system out of equilibrium that evolves towards thermalization. We show that the area of the past apparent horizon of these space-times satisfies a generalized Penrose inequality and we formulate as well as provide evidence for a suitable generalization of Thorne’s hoop conjecture. We also compute the holographic energy-momentum tensor and deduce its late time behavior. It turns out that the complete non-equilibrium process on the boundary is governed by Calabi’s flow on S 2 . Upon linearization, only special modes that arise as supersymmetric zero energy states of an associated supersymmetric quantum mechanics problem contribute to the solution. We find that each pole of radiation has an effective viscosity given by the eigenvalues of the Laplace operator on S 2 and there is an apparent violation of the KSS bound on η/s for the low lying harmonics of large AdS 4 black holes. These modes, however, do not satisfy Dirichlet boundary conditions, they are out-going and they do not appear to have a Kruskal extension across the future horizon H $$ \mathcal{H} $$ +
Di-Higgs phenomenology in tt¯hh : The forgotten channel

Searches for multi-Higgs final states allow to constrain parameters of the SM (or extensions thereof) that directly relate to the mechanism of electroweak symmetry breaking. Multi-Higgs production cross sections, however, are small and the phenomenologically accessible final states are challenging to isolate in the busy multi-jet hadron collider environment of the LHC run 2 and HL-LHC. This makes the necessity to extend the list of potentially observable production mechanisms obvious. Most of the phenomenological analyses in the past have focused on gg→hh+jets ; in this paper we study pp→tt¯hh at the HL-LHC and find that this channel for h→bb¯ and semi-leptonic and hadronic top decays has the potential to provide an additional handle to constrain the Higgs trilinear coupling in a global fit at the end of the high luminosity phase
Non-adiabatic effects within a single thermally averaged potential energy surface: Thermal expansion and reaction rates of small molecules

At non-zero temperature and when a system has low-lying excited electronic states, the ground-state Born–Oppenheimer approximation breaks down and the low-lying electronic states are involved in any chemical process. In this work, we use a temperature-dependent effective potential for the nuclei which can accommodate the influence of an arbitrary number of electronic states in a simple way, while at the same time producing the correct Boltzmann equilibrium distribution for the electronic part. With the help of this effective potential, we show that thermally activated low-lying electronic states can have a significant effect in molecular properties for which electronic excitations are oftentimes ignored. We study the thermal expansion of the Manganese dimer, Mn2, where we find that the average bond length experiences a change larger than the present experimental accuracy upon the inclusion of the excited states into the picture. We also show that, when these states are taken into account, reaction-rate constants are modified. In particular, we study the opening of the ozone molecule, O3, and show that in this case the rate is modified as much as a 20% with respect to the ground-state Born–Oppenheimer prediction.This work has been supported by the research grants E24/1 and E24/3 (DGA, Spain), FIS2008-01240, FIS2009- 13364-C02-01, FIS2009-12648, and FIS2011-25167 (MICINN, Spain, cofinanced by FEDER funds), and ARAID and Ibercaja grant for young researchers (Spain).

Enhanced laboratory diagnosis of human chlamydia pneumoniae infection through pattern recognition derived from pathology database analysis

This study focuses on pattern recognition in pathology data collected from patients tested for Chlamydia pneumoniae (Cp) infection, with co-infection by Mycoplasma pneumoniae (Myco) also considered. Both Cp and Myco are microbes that cause respiratory disease in some infected people. As well as the immunoassay results revealing whether the patient had been infected, or not, an extensive range of other routine pathology data was also available for each patient, allowing the analysis of associations between a positive immunoassay laboratory result for Cp or Myco, and a range of tests for biochemical and cellular markers (e.g. liver enzymes, electrolyte balance, haematological indices such as red/white cell counts). Decision trees and logistic regression were used to enhance laboratory diagnosis of these respiratory infections via the formulation of association rules derived from immunoassay results and associated pathology data.PRIB 2008 proceedings found at: http://dx.doi.org/10.1007/978-3-540-88436-
Marine Natural Product Aurilide Activates the OPA1-Mediated Apoptosis by Binding to Prohibitin.

Aurilide is a potent cytotoxic marine natural product that induces apoptosis in cultured human cells at the picomolar to nanomolar range; however, its mechanism of action has been unknown. Results of the present study showed that aurilide selectively binds to prohibitin 1 (PHB1) in the mitochondria, activating the proteolytic processing of optic atrophy 1 (OPA1) and resulting in mitochondria-induced apoptosis. The mechanism of aurilide cytotoxicity suggests that PHB1 is an apoptosis-regulating protein amenable to modulation by small molecules. Aurilide may serve as a small-molecule tool for studies of mitochondria-induced apoptosis
Dlg5 interacts with the TGF-β receptor and promotes its degradation.

Discs large homolog 5 (Dlg5) is a member of the membrane-associated guanylate kinase adaptor family of proteins and is involved in epithelial-to-mesenchymal transition via transforming growth factor-β (TGF-β) signaling. However, the mechanism underlying the regulation of TGF-β signaling is unclear. We show here that Dlg5 interacts and colocalizes with both TGF-β type I (TβRI) and type II (TβRII) receptors at the plasma membrane. TβRI activation is not required for this interaction. Furthermore, the overexpression of Dlg5 enhances the degradation of TβRI. Proteasome inhibitors inhibited this enhanced degradation. These results suggest that Dlg5 interacts with TβRs and promotes their degradation
Low-pH waters discharging from submarine vents at Panarea Island (Aeolian Islands, southern Italy) after the 2002 gas blast: origin of hydrothermal fluids and implications for volcanic surveillance.

A geochemical survey of thermal waters collected from submarine vents at Panarea Island (Aeolian Islands, southern Italy) was carried out from December 2002 to March 2007, in order to investigate i) the geochemical processes controlling the chemical composition of the hydrothermal fluids and ii) the possible relations between the chemical features of the hydrothermal reservoir and the activity of the magmatic system. Compositional data of the thermal water samples were integrated in a hydrological conceptual model, which describes the formation of the vent fluid by mixing of seawater, seawater concentrated by boiling, and a deep, highly-saline end-member, whose composition is regulated by water-rock interactions at relatively high temperature and shows clear clues of magmatic-related inputs. The chemical composition of concentrated seawater was assumed to be represented by that of the water sample having the highest Mg content. The composition of the deep end-member was instead calculated by extrapolation assuming a zero-Mg end-member. The Na–K–Ca geothermometer, when applied to the thermal end-member composition, indicated an equilibrium temperature of approximately 300 °C, a temperature in agreement with the results obtained by gas-geothermometry
First direct observations of the reduced striations at pump frequencies close to the electron gyroharmonics

It is well known that the ionospheric plasma response to high-power HF radio waves changes drastically as the heater frequency approaches harmonics of the electron gyrofrequency. These include changes in the spectrum of the stimulated electromagnetic emission, reduction in the anomalous absorption of low-power diagnostic waves propagating through the heated volume, and reduction in the large scale F-region heating. Theoretical models as well as previous experimental evidence point towards the absence of small-scale field-aligned plasma density irregularities at pump frequencies close to electron gyroharmonics as the main cause of these changes. Results presented in this paper are the first direct observations of the reduced striations at the 3rd gyroharmonic made by the CUTLASS radar. In addition, simultaneous EISCAT observations have revealed that the "enhanced ion-line" usually present in the EISCAT ion-line spectrum during the first few seconds after heater switch on, persisted at varying strengths while the heater was transmitting at frequencies close to the 3rd electron gyroharmonics.1071
The tectonic geomorphology of bedrock scarps on active normal faults in the Italian Apennines mapped using combined ground penetrating radar and terrestrial laser scanning.

Using combined datasets from ground penetrating radar (GPR) and terrestrial laser scanning (TLS) we document the variety of tectono-geomorphic features that contribute to the morphology of bedrock scarps associated with active extensional faulting in central Italy. Measurement of faulted offsets across such scarps can provide important fault slip-rate data relevant to seismic hazard analysis if ages can be established for offset features. However, interpretation of these offsets is challenging when geomorphic processes as well as fault slip contribute to exhumation of the bedrock during scarp development. Through the integration of surface (TLS) and subsurface (GPR) datasets, we show that the surface expression of three bedrock scarps results from the interaction between footwall incision, hangingwall sedimentation, channel incision and landsliding as well as fault slip and fault linkage. We further illustrate how these processes can be differentiated to identify locations suitable for determining fault slip-rates. The identification of such features has important implications for our understanding of the relationship between bedrock faulting and geomorphic processes, in turn contributing to improved assessment of fault slip-rates in the central Apennines. The use of combined GPR and TLS datasets here has shown that the tectono-geomorphic features of the studied scarps vary greatly over short distances and we emphasise the need for detailed scarp analysis to elucidate the processes responsible for bedrock exhumation before estimating the rates of fault slip over the timescale of scarp formation
On cuspidal representations of general linear groups over discrete valuation rings.

We define a new notion of cuspidality for representations of GL n over a finite quotient o k of the ring of integers o of a non-Archimedean local field F using geometric and infinitesimal induction functors, which involve automorphism groups G λ of torsion o-modules. When n is a prime, we show that this notion of cuspidality is equivalent to strong cuspidality, which arises in the construction of supercuspidal representations of GL n (F). We show that strongly cuspidal representations share many features of cuspidal representations of finite general linear groups. In the function field case, we show that the construction of the representations of GL n (o k ) for k ≥ 2 for all n is equivalent to the construction of the representations of all the groups G λ . A functional equation for zeta functions for representations of GL n (o k ) is established for representations which are not contained in an infinitesimally induced representation. All the cuspidal representations for GL4(o2) are constructed. Not all these representations are strongly cuspidal
A finite volume method for scalar conservation laws with stochastic time-space dependent flux function.

We propose a new finite volume method for scalar conservation laws with stochastic time–space dependent flux functions. The stochastic effects appear in the flux function and can be interpreted as a random manner to localize the discontinuity in the time–space dependent flux function. The location of the interface between the fluxes can be obtained by solving a system of stochastic differential equations for the velocity fluctuation and displacement variable. In this paper we develop a modified Rusanov method for the reconstruction of numerical fluxes in the finite volume discretization. To solve the system of stochastic differential equations for the interface we apply a second-order Runge–Kutta scheme. Numerical results are presented for stochastic problems in traffic flow and two-phase flow applications. It is found that the proposed finite volume method offers a robust and accurate approach for solving scalar conservation laws with stochastic time–space dependent flux functions
Predicting Chinese human resource managers' strategic competence : roles of identity, career variety, organizational support and career adaptability.

Based on career construction theory, the predictors of human resource managers' strategic competence in the Chinese context were examined. Results from a survey administered to Chinese HR managers (N = 220) showed that professional identification, career variety and organizational support for strategic human resource management positively predicted Chinese human resource managers' strategic competence. In addition, career adaptability served as a significant mediator for the above relations. The results further showed that the effect of professional identification on career adaptability was stronger among employees who perceived a higher (vs. lower) level of organizational support for strategic human resource management. The corresponding moderated mediation model was also supported such that the indirect effect of professional identification on strategic competence was stronger among employees who perceived a higher (vs. lower) level of organizational support for strategic human resource management. These findings carry implications for career construction theory and human resource managers' career development in China
An improved multiple model particle filtering approach for manoeuvring target tracking using airborne GMTI with geographic information

This is an open access article under the CC BY\ud
license (http://creativecommons.org/licenses/by/4.0/).This paper proposes a ground vehicle tracking method using an airborne ground moving target indicator radar where the surrounding geographic information is considered to determine vehicle's movement type as well as constrain its positions. Multiple state models corresponding to different movement modes are applied to represent the vehicle's behaviour in different terrain conditions. Based on geographic conditions and multiple state models, a constrained variable structure multiple model particle filter algorithm is proposed. Compared with the traditional multiple model particle filtering schemes, the proposed algorithm utilises a particle swarm optimisation technique which generates more effective particles and generated particles are constrained into the feasible geographic region. Numerical simulation results in a realistic environment show that the proposed method achieves better tracking performance compared with current state-of-the-art ones for manoeuvring vehicle tracking
Melt-Quenched Glasses of Metal?Organic Frameworks

Crystalline solids dominate the field of metal?organic frameworks (MOFs), with access to the liquid and glass states of matter usually prohibited by relatively low temperatures of thermal decomposition. In this work, we give due consideration to framework chemistry and topology to expand the phenomenon of the melting of 3D MOFs, linking crystal chemistry to framework melting temperature and kinetic fragility of the glass-forming liquids. Here we show that melting temperatures can be lowered by altering the chemistry of the crystalline MOF state, which provides a route to facilitate the melting of other MOFs. The glasses formed upon vitrification are chemically and structurally distinct from the three other existing categories of melt-quenched glasses (inorganic nonmetallic, organic, and metallic), and retain the basic metal?ligand connectivity of crystalline MOFs, which connects their mechanical properties to their starting chemical composition. The transfer of functionality from crystal to glass points toward new routes to tunable, functional hybrid glasses.publishersversionPeer reviewe
Measuring dark energy with the $E_{\rm iso}-E_{\rm p}$ correlation of
  gamma-ray bursts using model-independent methods

In this paper, we use two model-independent methods to standardize long
gamma-ray bursts (GRBs) using the $E_{\rm iso}-E_{\rm p}$ correlation, where
$E_{\rm iso}$ is the isotropic-equivalent gamma-ray energy and $E_{\rm p}$ is
the spectral peak energy. We update 42 long GRBs and try to make constraint on
cosmological parameters. The full sample contains 151 long GRBs with redshifts
from 0.0331 to 8.2. The first method is the simultaneous fitting method. The
extrinsic scatter $\sigma_{\rm ext}$ is taken into account and assigned to the
parameter $E_{\rm iso}$. The best-fitting values are $a=49.15\pm0.26$,
$b=1.42\pm0.11$, $\sigma_{\rm ext}=0.34\pm0.03$ and $\Omega_m=0.79$ in the flat
$\Lambda$CDM model. The constraint on $\Omega_m$ is $0.55<\Omega_m<1$ at the
1$\sigma$ confidence level. If reduced $\chi^2$ method is used, the best-fit
results are $a=48.96\pm0.18$, $b=1.52\pm0.08$ and $\Omega_m=0.50\pm0.12$. The
second method is using type Ia supernovae (SNe Ia) to calibrate the $E_{\rm
iso}-E_{\rm p}$ correlation. We calibrate 90 high-redshift GRBs in the redshift
range from 1.44 to 8.1. The cosmological constraints from these 90 GRBs are
$\Omega_m=0.23^{+0.06}_{-0.04}$ for flat $\Lambda$CDM, and
$\Omega_m=0.18\pm0.11$ and $\Omega_{\Lambda}=0.46\pm0.51$ for non-flat
$\Lambda$CDM. For the combination of GRB and SNe Ia sample, we obtain
$\Omega_m=0.271\pm0.019$ and $h=0.701\pm0.002$ for the flat $\Lambda$CDM, and
for the non-flat $\Lambda$CDM, the results are $\Omega_m=0.225\pm0.044$,
$\Omega_{\Lambda}=0.640\pm0.082$ and $h=0.698\pm0.004$. These results from
calibrated GRBs are consistent with that of SNe Ia. Meanwhile, the combined
data can improve cosmological constraints significantly, comparing to SNe Ia
alone. Our results show that the $E_{\rm iso}-E_{\rm p}$ correlation is
promising to probe the high-redshift universe.Comment: 10 pages, 6 figures, 4 table, accepted by A&A. Table 4 contains

Nuclear structure corrections to the Lamb shift in $\mu^3$He$^+$ and
  $\mu^3$H

Measuring the 2S-2P Lamb shift in a hydrogen-like muonic atom allows one to
extract its nuclear charge radius with a high precision that is limited by the
uncertainty in the nuclear structure corrections. The charge radius of the
proton thus extracted was found to be 7-sigma away from the CODATA value, in
what has become the yet unsolved "proton radius puzzle". Further experiments
currently aim at the isotopes of hydrogen and helium: the precise extraction of
their radii may provide a hint at the solution of the puzzle. We present the
first ab initio calculation of nuclear structure corrections, including the
nuclear polarization correction, to the 2S-2P transition in $\mu^3$He$^+$ and
$\mu^3$H, and assess solid theoretical error bars. Our predictions reduce the
uncertainty in the nuclear structure corrections to the level of a few percents
and will be instrumental to the on-going $\mu^3$He$^+$ experiment. We also
support the mirror $\mu\,^3$H system as a candidate for further probing of the
nucleon polarizabilities and shedding more light on the puzzle.Comment: 7 pgs., 1 fig., 1 table, plus Supplementary Materials (3 pgs., 2

All-loop correlators of integrable $\lambda$-deformed $\sigma$-models

We compute the 2- and 3-point functions of currents and primary fields of
$\lambda$-deformed integrable $\sigma$-models characterized also by an integer
$k$. Our results apply for any semisimple group $G$, for all values of the
deformation parameter $\lambda$ and up to order $1/k$. We deduce the OPEs and
equal-time commutators of all currents and primaries. We derive the currents'
Poisson brackets which assume Rajeev's deformation of the canonical structure
of the isotropic PCM, the underlying structure of the integrable
$\lambda$-deformed $\sigma$-models. We also present analogous results in two
limiting cases of special interest, namely for the non-Abelian T-dual of the
PCM and for the pseudodual model.Comment: 30 pages plus appendices; v2: few minor changes, NPB versio
