Cyclic vectors for backward hyponormal weighted shifts [PDF]
Proceedings of the American Mathematical Society, 1986 A unilateral weighted shift T T on a Hilbert space H H is an operator such that T e n = w n e n + 1

Backward Shifts on Banach SpacesC(X)
Journal of Mathematical Analysis and Applications, 1996 A backward shift on a Banach space \(E\) is an operator \(T\) with one-dimensional kernel such that the corresponding operator from the quotient of \(E\) by the kernel of \(T\) is an isometry and so that \(\bigcup_{n\geq 1}\text{Ker }T^n\) is dense in \(E\). The authors settle a conjecture of J. R.

Saccades influence the visibility of targets in rapid stimulus sequences: the roles of mislocalization, retinal distance and remapping [PDF]
, 2016 Briefly presented targets around the time of a saccade are mislocalized towards the saccadic landing point. This has been taken as evidence for a remapping mechanism that accompanies each eye movement, helping maintain visual stability across large ...

All-Silicon Energy-Efficient Optical Diode Using Opto-Mechanical Microring Resonators
IEEE Photonics Journal, 2020 By utilizing two cascaded all-silicon opto-mechanical microring resonators (MRRs), an energy-efficient optical diode with high nonreciprocal transmission ratios (NTRs) is proposed and experimentally realized.

Representational momentum and the human face : an empirical note [PDF]
, 2014 Recent evidence suggests that observers may anticipate the future emotional state of an actor when viewing dynamic expressions of emotion, consistent with the notion of representational momentum.

Saccadic adaptation alters the attentional field
Frontiers in Human Neuroscience, 2016 It is currently unknown whether changes to the oculomotor system can induce changes to the distribution of spatial attention around a fixated target.

Distributional chaos for backward shifts
Journal of Mathematical Analysis and Applications, 2009 In the paper under review, one of the main purposes of the authors is to give several conditions ensuring uniform distributional chaos for backward shifts. They also compare distributional chaos with Devaney chaos and hypercyclicity, and show that Devaney chaos implies uniform distributional chaos for weighted backward shifts, but there are examples of

The newfound relationship between extrachromosomal DNAs and excised signal circles
FEBS Letters, EarlyView.Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...
