A family of degenerate elliptic operators: maximum principle and its consequences
Isabeau Birindelli, Giulio Galise, Hitoshi Ishii
In this paper we investigate the validity and the consequences of the maximum principle for degenerate elliptic operators whose higher order term is the sum of "k" eigenvalues of t…
Hessenberg varieties and hyperplane arrangements
Takuro Abe, Tatsuya Horiguchi, Mikiya Masuda +2
Given a semisimple complex linear algebraic group and a lower ideal in positive roots of , three objects arise: the ideal arrangement , the regular nilpot…
Change point detection in autoregressive models with no moment assumptions
Fumiya Akashi, Holger Dette, Yan Liu
In this paper we consider the problem of detecting a change in the parameters of an autoregressive process, where the moments of the innovation process do not necessarily exist. An…
The linear stability of the post-Newtonian triangular equilibrium in the three-body problem
Kei Yamada, Takuya Tsuchiya
Continuing work initiated in an earlier publication [Yamada, Tsuchiya, and Asada, Phys. Rev. D 91, 124016 (2015)], we reexamine the linear stability of the triangular solution in t…
Measurement of the cross-section for producing a boson in association with a single top quark in collisions at TeV with ATLAS
ATLAS Collaboration
The inclusive cross-section for the associated production of a boson and top quark is measured using data from proton-proton collisions at TeV. The dataset corr…

ATLAS Collaboration
Ratios of top-quark pair to -boson cross sections measured from proton--proton collisions at the LHC centre-of-mass energies of TeV, 8TeV, and 7TeV are presented by…
Precision measurement and interpretation of inclusive , and production cross sections with the ATLAS detector
ATLAS Collaboration
High-precision measurements by the ATLAS Collaboration are presented of inclusive , and () Drell-Yan production cros…
Measurement of the prompt pair production cross-section in collisions at TeV with the ATLAS detector
ATLAS Collaboration
The production of two prompt mesons, each with transverse momenta GeV and rapidity , is studied using a sample of proton-proton collisions at…
Measurement of the boson polarisation in events from collisions at = 8 TeV in the lepton+jets channel with ATLAS
ATLAS Collaboration
This paper presents a measurement of the polarisation of bosons from decays, reconstructed in events with one high-$p_{\mbox{T}}$ lepton and at least four jets. Data…
Supernova equations of state including full nuclear ensemble with in-medium effects
Shun Furusawa, Kohsuke Sumiyoshi, Shoichi Yamada +1
We construct new equations of state for baryons at sub-nuclear densities for the use in core-collapse supernova simulations. The abundance of various nuclei is obtained together wi…
Dark matter physics, flavor physics and LHC constraints in the dark matter model with a bottom partner
Tomohiro Abe, Junichiro Kawamura, Shohei Okawa +1
In the scenario that a dark matter (DM) is a weakly interacting massive particle, there are many possibilities of the interactions with the Standard Model (SM) particles to achieve…
Electron efficiency measurements with the ATLAS detector using 2012 LHC proton-proton collision data
ATLAS Collaboration
This paper describes the algorithms for the reconstruction and identification of electrons in the central region of the ATLAS detector at the Large Hadron Collider (LHC). These alg…
On a role of corotation radius in the low dynamical instability of differentially rotating stars
Shin'ichirou Yoshida, Motoyuki Saijo
We investigate the nature of so-called low dynamical instability in a differentially rotating star by focusing on the role played by the corotation radius of the unstable osc…
On global well-posedness for nonlinear semirelativistic equations in some scaling subcritical and critical cases
Kazumasa Fujiwara, Vladimir Georgiev, Tohru Ozawa
In this paper, the global well-posedness of semirelativistic equations with a power type nonlinearity on Euclidean spaces is studied. In two dimensional scaling subcritical c…
Remarks on the Rellich inequality
Shuji Machihara, Tohru Ozawa, Hidemitsu Wadade
We study the Rellich inequalities in the framework of equalities. We present equalities which imply the Rellich inequalities by dropping remainders. This provides a simple and dire…
Photodetection in p-n junctions formed by electrolyte-gated transistors of two-dimensional crystals
Daichi Kozawa, Jiang Pu, Ryo Shimizu +8
Transition metal dichalcogenide (TMDC) monolayers have attracted much attention due to their strong light absorption and excellent electronic properties. These advantages make this…

Neal Bez, Chris Jeavons, Tohru Ozawa +1
We prove stable versions of trace theorems on the sphere in with optimal constants, thus obtaining rather precise information regarding near-extremisers. We also obtain stabi…
