An expert opinion in speech and language therapy: The Queen Square Intensive Comprehensive Aphasia Programme

Less is more, right? Wrong: more is more. Here we make the case that the total dose of speech and language therapy (SLT) is a key factor in improving persons with aphasia’s (PWA) outcomes. The challenge is: how can we deliver high-dose therapy when resources are stretched? We review the recent evidence for dose and timing of SLT and then describe one solution to the problem of dose that we are trialing at Queen Square, an Intensive Comprehensive Aphasia Programme (ICAP)

Measurement of the differential cross-section of B + meson production in pp collisions at √s=7 TeV at ATLAS

The production cross-section of B + mesons is measured as a function of transverse momentum p T and rapidity y in proton-proton collisions at centre-of-mass energy s√=7 TeV, using 2.4 fb−1 of data recorded with the ATLAS detector at the Large Hadron Collider. The differential production cross-sections, determined in the range 9 GeV < p T < 120 GeV and |y| < 2.25, are compared to next-to-leading-order theoretical predictions

Dynamics of isolated-photon plus jet production in pp collisions at √s=7 TeV with the ATLAS detector

The dynamics of isolated-photon plus jet production in pp collisions at a centre-of-mass energy of 7 TeV has been studied with the ATLAS detector at the LHC using an integrated luminosity of 37 pb−1. Measurements of isolated-photon plus jet bin-averaged cross sections are presented as functions of photon transverse energy, jet transverse momentum and jet rapidity. In addition, the bin-averaged cross sections as functions of the difference between the azimuthal angles of the photon and the jet, the photon–jet invariant mass and the scattering angle in the photon–jet centre-of-mass frame have been measured. Next-to-leading-order QCD calculations are compared to the measurements and provide a good description of the data, except for the case of the azimuthal opening angle

Measurement of jet shapes in top-quark pair events at √s =7 TeV using the ATLAS detector

A measurement of jet shapes in top-quark pair events using 1.8 fb−1 of √s=7 TeV pp collision data recorded by the ATLAS detector at the LHC is presented. Samples of top-quark pair events are selected in both the single-lepton and dilepton final states. The differential and integrated shapes of the jets initiated by bottom-quarks from the top-quark decays are compared with those of the jets originated by light-quarks from the hadronic W-boson decays W→qq¯′ in the single-lepton channel. The light-quark jets are found to have a narrower distribution of the momentum flow inside the jet area than b-quark jets

Measurement of the production cross section of jets in association with a Z boson in pp collisions at √s=7 TeV with the ATLAS detector

Measurements of the production of jets of particles in association with a Z boson in pp collisions at s√=7 TeV are presented, using data corresponding to an integrated luminosity of 4.6 fb−1 collected by the ATLAS experiment at the Large Hadron Collider. Inclusive and differential jet cross sections in Z events, with Z decaying into electron or muon pairs, are measured for jets with transverse momentum p T > 30 GeV and rapidity |y| < 4.4. The results are compared to next-to-leading-order perturbative QCD calculations, and to predictions from different Monte Carlo generators based on leading-order and next-to-leading-order matrix elements supplemented by parton showers

Separated Fringe Packet Observations with the CHARA Array III. The Very High Eccentricity Binary HR 7345

After an eleven year observing campaign, we present the combined visual{spectroscopic orbit of the formerly unremarkable bright star HR 7345 (HD 181655, HIP 94981, GJ 754.2). Using the Separated Fringe Packet (SFP) method with the CHARA Array, we were able to determine a difficult to complete orbital period of 331.609 +/- 0.004 days. The 11 month period causes the system to be hidden from interferometric view behind the Sun for 3 years at a time. Due to the high eccentricity orbit of about 90% of a year, after 2018 January the periastron phase will not be observable again until late 2021. Hindered by its extremely high eccentricity of 0.9322 +/- 0.0001, the double-lined spectroscopic phase of HR 7345 is observable for 15 days. Such a high eccentricity for HR 7345 places it among the most eccentric systems in catalogs of both visual and spectroscopic orbits. For this system we determine nearly identical component masses of 0.941 +/- 0.076 Msun and 0.926 +/- 0.075 Msun as well as an orbital parallax of 41.08 +/- 0.77 mas.Comment: 20 pages, 3 figures, 4 table

Measurement of the azimuthal angle dependence of inclusive jet yields in Pb+Pb collisions at √sNN=2.76 TeV with the ATLAS detector

Measurements of the variation of inclusive jet suppression as a function of relative azimuthal angle, Δϕ, with respect to the elliptic event plane provide insight into the path-length dependence of jet quenching. ATLAS has measured the Δϕ dependence of jet yields in 0.14  nb-1 of √sNN=2.76  TeV Pb+Pb collisions at the LHC for jet transverse momenta pT>45  GeV in different collision centrality bins using an underlying event subtraction procedure that accounts for elliptic flow. The variation of the jet yield with Δϕ was characterized by the parameter, v2jet, and the ratio of out-of-plane (Δϕ∼π/2) to in-plane (Δϕ∼0) yields. Nonzero v2jet values were measured in all centrality bins for pT<160  GeV. The jet yields are observed to vary by as much as 20% between in-plane and out-of-plane directions

TeleCPT: Delivery of a Better Conversations Approach to Communication Partner Training During a Global Pandemic and Beyond

Purpose: This case report provides an overview of telehealth delivery of our Better Conversations approach to communication partner training (CPT) for people with primary progressive aphasia (PPA) and their communication partner (CP). The purpose is to advance the knowledge of speech and language therapists/pathologists (SLTs) on this type of CPT and empower them to deliver teleCPT as part of their clinical practice. // Method: We provide a case report describing therapy delivery, outcomes, and self-reflections from our clinical practice, which represents a collaboration between a UK National Health Service CPT clinic and the Better Conversations Research Lab at University College London, UK. A man with PPA and his CP (a dyad) video-recorded everyday conversations at home using a video conferencing platform. These formed the basis of an evaluation of conversation barriers and facilitators, which led to four weekly 1-hr therapy sessions covering the mechanics of conversation, identification of barriers and facilitators, goal setting, and practice of positive conversation strategies. // Results: Dyad self-rating of goal attainment revealed that three of four conversation strategies were achieved much more than expected, a positive outcome given the progressive nature of F.F.'s condition. SLT access to the dyad at home via teleCPT facilitated the carryover of strategies from the session to everyday conversations in the home environment. TeleCPT was acceptable to this couple during a global pandemic, with benefits including no travel, ease of therapy scheduling around the CP's work and family commitments, and access to a specialist CPT clinic outside their geographical area. // Conclusions: TeleCPT is feasible and acceptable to clients, improving access to therapy in a way that should not just be the preserve of service delivery during a global pandemic. SLTs can enable clients and their families to have better conversations despite communication difficulties by offering teleCPT. We have shared practical suggestions for delivering teleCPT

Measurement of the production cross section of prompt J/ψ mesons in association with a W± boson in pp collisions at p s = 7 TeV with the ATLAS detector

The process pp → W±J/ψ provides a powerful probe of the production mechanism of charmonium in hadronic collisions, and is also sensitive to multiple parton interactions in the colliding protons. Using the 2011 ATLAS dataset of 4.5 fb-1 of p s = 7TeV pp collisions at the LHC, the first observation is made of the production of W± + prompt J/ events in hadronic collisions, using W± → μ and J/ψ → μ+μ-. A yield of 27.4±7.5 -6.5 W± + prompt J/ψ events is observed, with a statistical significance of 5.1. The production rate as a ratio to the inclusive W± boson production rate is measured, and the double parton scattering contribution to the cross section is estimated

Search for direct third-generation squark pair production in final states with missing transverse momentum and two b-jets in √s=8 TeV pp collisions with the ATLAS detector

The results of a search for pair production of supersymmetric partners of the Standard Model third-generation quarks are reported. This search uses 20.1 fb−1 of pp collisions at √s=8 TeV collected by the ATLAS experiment at the Large Hadron Collider. The lightest bottom and top squarks ( b˜1 and t˜1 respectively) are searched for in a final state with large missing transverse momentum and two jets identified as originating from b-quarks. No excess of events above the expected level of Standard Model background is found. The results are used to set upper limits on the visible cross section for processes beyond the Standard Model. Exclusion limits at the 95 % confidence level on the masses of the third-generation squarks are derived in phenomenological supersymmetric R-parity-conserving models in which either the bottom or the top squark is the lightest squark. The b˜1 is assumed to decay via b˜1→b∼χ01 and the t˜1 via t˜1→b∼χ1± , with undetectable products of the subsequent decay of the ∼χ1± due to the small mass splitting between the ∼χ1± and the ∼χ01
