We report a new determination of q?, the jet transport coefficient quark-gluon plasma. use JETSCAPE framework, which incorporates novel multistage theoretical approach to in-medium evolution and Bayesian inference for parameter extraction. The calculations, based on Matter Lbt quenching models, are compared experimental measurements inclusive hadron suppression in Au+Au collisions at BNL Relati...

Generalizing [ShSp], for every n < ω we construct a ZFC-model where h(n), the distributivity number of r.o.(P(ω)/fin)n, is greater than h(n+ 1). This answers an old problem of Balcar, Pelant and Simon (see [BaPeSi]). We also show that both Laver and Miller forcings collapse the continuum to h(n) for every n < ω, hence by the first result, consistently they collapse it below h(n). Introduction. ...

the effect of a combined system of the bed suction and jet injection as a pier-scour countermeasure on the turbulent flow field is studied in a laboratory flume using an acoustic doppler velocimeter (adv). the three components of the velocities in the vertical symmetry plane in the equilibrium scour hole in front and rear of the pier under 3-jet injections and bed suction rate qs/q0 = 2%located...

According to the Smoluchowski-Kramers approximation, the solution of the equation μq̈ t = b(q μ t ) − q̇ t + Σ(q t )Ẇt, q 0 = q, q̇ 0 = p converges to the solution of the equation q̇t = b(qt) + Σ(qt)Ẇt, q0 = q as μ → 0. We consider here a similar result for the Langevin process with elastic reflection on the boundary.

The case is simple: there is no compelling theoretical argument against a cosmological constant and ΛCDM is the only CDM model that is consistent with all present observations. ΛCDM has two noteworthy features: it can be falsified in the near future (the prediction q0 ∼ − 1 2 is an especially good test), and, if correct, it has important implications for fundamental physics.

Let k be a field and A a finite dimensional (associative with 1) k-algebra. By modA we denote the category of finite dimensional left A-modules. In many important situations we may suppose that A is presented as a quiver with relations (Q, I) (e.g. if k is algebraically closed, then A is Morita equivalent to kQ/I). We recall that if A is presented by (Q, I), then Q is a finite quiver and I is a...

Application prospects in automotive industry have led to extensive studies on 6xxx alloys in recent years. These alloys often contain Cu in varying amounts. This leads to the formation of the quaternary Al–Mg–Si–Cu family of alloys that may exist either as a 6xxx or a 2xxx alloy. These alloys have distinctive properties in part due to the occurrence of a phase, designated as Q, which is stable ...
