Inferring black hole charge from backscattered electromagnetic radiation [PDF]
We compute the scattering cross section of Reissner-Nordström black holes for the case of an incident electromagnetic wave. We describe how scattering is affected by both the conversion of electromagnetic to gravitational radiation, and the parity ...

Curvature and the Backward Shift Operators [PDF]
Let φ α {\varphi _\alpha } be a Möbius transformation of the unit disk D {\mathbf {D}} , | α | > 1 \left | \alpha \right | > 1 . We characterize all the operators T

Translational Optic Flow Induces Shifts in Direction of Active Forward and Backward Self-Motion
Previously, we reported that when observers passively experience real linear oscillatory somatic motion while viewing orthogonal visual optic flow patterns, their perceived motion direction is intermediate to those specified by visual and vestibular ...

Mixing unilateral backward shifts
In this paper, we characterize mixing unilateral backward shifts on barrelled and ultrabarrelled topological sequence spaces respectively, which extend several well-known results in the existing literature. We present some nontrivial examples to show the validity of our results.

Generalized Backward Shifts on Banach Spaces
For a bounded linear operator \(T\) on a Banach space \(X\), \(\text{Ker\,}T\) and \(\text{Ran\,}T\) denote respectively the kernel and range of \(T\). \(T\) is said to be a generalized forward shift if (1) \(T\) is an isometry on \(X\), (2) \(\text{Ran\,}T\) is of \(\text{codim\,}1\), (3) \(\bigcap_{n\geq 1}\text{Ran\,}T^n= \{0\}\).

Doppler-Based Acoustic Gyrator
Non-reciprocal phase shifters have been attracting a great deal of attention due to their important applications in filtering, isolation, modulation, and mode locking.

Personnel shift assignment: Existence conditions and network models [PDF]
The personnel scheduling problem is known to be a five-stage process in which the final stage involves the assignment of shifts to the days worked in the schedule.

Experience and abstract reasoning in learning backward induction
Backward induction is a benchmark of game theoretic rationality, yet surprisingly little is known as to how humans discover and initially learn to apply this abstract solution concept in experimental settings.

Detecting patterns of species diversification in the presence of both rate shifts and mass extinctions [PDF]
Recent methodological advances are enabling better examination of speciation and extinction processes and patterns. A major open question is the origin of large discrepancies in species number between groups of the same age.
