Pseudocontinuations and the backward shift [PDF]
Indiana University Mathematics Journal, 1998 We examine the backward shift operator \(Lf= (f-f(0))/z\) on certain Banach spaces of analytic functions on the open unit disk \(D\). In particular, for a (closed) subspace \(M\) for which \(LM\subset M\), we wish to determine the spectrum, the point spectrum, and the approximate point spectrum of \(L| M\).

The apparent Coulomb reacceleration of neutrons in electrodissociation of the deuteron [PDF]
, 1994 We demonstrate that the final state $p$-$n$ interaction in the reaction of electrodissociation of the deuteron at large $Q^{2}$ in a static external field leads to the apparent reacceleration of neutrons.

Leibenzon’s backward shift and composition operators [PDF]
Proceedings of the American Mathematical Society, 2001 Let \(n\) be a positive integer, and let \(B= B_n\) denote the open unit ball of the complex Euclidean space \(C_n\). If \(\varphi:B\to B\) is holomorphic, then the composition operator \({\mathcal C}_\varphi\) is defined by \({\mathcal C}_\varphi(f)(z)= f(\varphi(z))\), \(z\in B\), where \(f: B\to C\) is holomorphic. If \(1< p< \infty\), then the norm

Neuromechanics of Dynamic Balance Tasks in the Presence of Perturbations
Frontiers in Human Neuroscience, 2021 Understanding the neuromechanical responses to perturbations in humans may help to explain the reported improvements in stability performance and muscle strength after perturbation-based training.

Brillouin-zone definition in non-reciprocal Willis monatomic lattices [PDF]
JASA Express Letters, 2023 Brillouin-zone (BZ) definition in a class of non-reciprocal Willis monatomic lattices (WMLs) is analytically quantified. It is shown that BZ boundaries only shift in response to non-reciprocity in one-dimensional WMLs, implying a constant BZ width, with ...

Curvature and the Backward Shift Operators [PDF]
Proceedings of the American Mathematical Society, 1984 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

Mixing unilateral backward shifts
, 2022 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
Journal of Mathematical Analysis and Applications, 2001 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) \(\bigcap_{n\geq 1}\text{Ran\,}T^n= \{0\}\).

Comparison of cardiovascular risk factors, gastrointestinal and musculoskeletal complications in different patterns of shift work in tile industry [PDF]
طب کار, 2013 Background: shift work may lead to different health problems due to circadian rhythm. The pattern of shift work, forward or backward, and the duration of each shift period may affect complications. This study was designed to assess and compare the health

Postnatal ontogeny and the evolution of macrostomy in snakes [PDF]
Royal Society Open Science, 2016 Macrostomy is the anatomical feature present in macrostomatan snakes that permits the ingestion of entire prey with high cross-sectional area. It depends on several anatomical traits in the skeleton and soft tissues, of which the elongation of gnathic ...
