Extended hydrodynamic equations for binary granular mixtures [PDF]
EPJ Web of ConferencesThe derivation of 2 × 14-moment equations for a dilute binary granular mixture is outlined, following Grad’s moment method. In addition to the mass, momentum and energy equations for each species, the deviatoric stress tensor, the heat flux vector and ...

Vector-like quarks with a scalar triplet
Physics Letters B, 2015 We study a minimal extension to the Standard Model with an additional real scalar triplet, Σ, and a single vector-like quark, T. This class of models appear naturally in extensions of the Littlest Higgs model that incorporate dark matter without the need

More stringy effects in target space from Double Field Theory
Journal of High Energy Physics, 2020 In Double Field Theory, the mass-squared of doubled fields associated with bosonic closed string states is proportional to N L + N R − 2. Massless states are therefore not only the graviton, anti-symmetric, and dilaton fields with (N L = 1, N R = 1) such

Multidirectional Motion Strategy of Miniature Water Surface Robot Actuated by Single Exciter
Advanced Robotics Research, EarlyView.A novel multidirectional motion strategy on the water surface based on a single exciter is proposed, and a single‐exciter single‐plate module is developed for actuation. The driving forces generation mechanism of the module is revealed from the perspective of the asymmetric surface wave field.

About a conjecture on quadratic vector fields
Journal of Pure and Applied Algebra, 2001 Let \(U\) be a partial differential field of characteristic 0 with differentiations \(\delta_{1},\dots ,\delta_{m}\) and \(R\) be a factorial differential subring of \(U\) with a field of quotients \(F\). Denote by \(C\) a field of constants of \(F\).

Advanced Robotics Research, EarlyView.Pak Biawak, a necrobot, embodies an unusual fusion of biology and robotics. Designed to repurpose natural structures after death, it challenges conventional boundaries between nature and engineering. Its movements are precise yet unsettling, raising questions about sustainability, ethics, and the untapped potential of biointegrated machines.

Phantom space–times in fake supergravity
Physics Letters B, 2015 We discuss phantom metrics admitting Killing spinors in fake N=2, D=4 supergravity coupled to vector multiplets. The Abelian U(1) gauge fields in the fake theory have kinetic terms with the wrong sign.
