Phantom distribution functions for some stationary sequences [PDF]
, 2015 The notion of a phantom distribution function (phdf) was introduced by O'Brien (1987). We show that the existence of a phdf is a quite common phenomenon for stationary weakly dependent sequences.

Index Reduction for Differential-algebraic Equations with Mixed Matrices [PDF]
Journal of the ACM, 2018 Differential-algebraic equations (DAEs) are widely used for the modeling of dynamical systems. The difficulty in numerically solving a DAE is measured by its differentiation index. For highly accurate simulation of dynamical systems, it is important to convert high-index DAEs into low-index DAEs.

Mu-tau neutrino refraction and collective three-flavor transformations in supernovae [PDF]
, 2008 We study three-flavor collective neutrino transformations in the dense-neutrino region above the neutrino sphere of a supernova core. We find that two-flavor conversions driven by the atmospheric mass difference and the 13-mixing angle capture the full ...

Mixing Enhancement in Serpentine Micromixers with a Non-Rectangular Cross-Section
Micromachines, 2018 In this numerical study, a new type of serpentine micromixer involving mixing units with a non-rectangular cross-section is investigated. Similar to other serpentine/spiral shaped micromixers, the design exploits the formation of transversal vortices ...

Mixing Optimization in Grooved Serpentine Microchannels
Micromachines, 2020 Computational fluid dynamics modeling at Reynolds numbers ranging from 10 to 100 was used to characterize the performance of a new type of micromixer employing a serpentine channel with a grooved surface. The new topology exploits the overlap between the

Index Modulation–Aided Mixed Massive Random Access [PDF]
Frontiers in Communications and Networks, 2021 In this study, a mixed massive random access scheme is considered where part of users transmit both common information and user-specific information, while others transmit only common information. In this scheme, common information is transmitted by index modulation (IM)–aided unsourced random access (URA), while user-specific information is by IM ...
