On X ̃-frames and conjugate systems in Banach spaces
Sahand Communications in Mathematical Analysis, 2014 The generalization of p-frame in Banach spaces is considered in this paper. The concepts of an X~-frame and a system conjugate to X~-frame were introduced. Analogues of the results on the existence of conjugate system were obtained.

Harmonik und Aufführungspraxis [PDF]
Zeitschrift der Gesellschaft für Musiktheorie, 2009 Wie lässt sich Harmonik aufführungspraktisch interpretieren? Diese Frage erscheint ungewohnt, sind es doch vorherrschend andere musikalische Parameter, welchen aufführungspraktische Relevanz beigemessen wird: dem Rhythmisch-Metrischen hinsichtlich Agogik

Higher-harmonic adaptation and the detection of squarewave gratings [PDF]
, 1987 Adaptation to a high contrast sinewave grating of 1 c/deg spatial frequency causes a large increase in the contrast threshold for a 1 c/deg test grating, but fails to raise the threshold for a squarewave grating of 0.33 c/deg, although the sensitivity of

Harmonic and relative harmonic dimensions
Annales Academiae Scientiarum Fennicae. Series A. I. Mathematica, 1985 On an open Riemann surface R of Heins type (i.e. R is parabolic with a single ideal boundary component, \(\delta\) R), this paper considers the relationship between the harmonic dimension of the ideal boundary, dim \(\delta\) R, and the relative harmonic dimension of the ideal boundary, \(\dim_ F\delta R\).

Impact of Asymptomatic Intracranial Hemorrhage on Outcome After Endovascular Stroke Treatment
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background Endovascular treatment (EVT) achieves high rates of recanalization in acute large‐vessel occlusion (LVO) stroke, but functional recovery remains heterogeneous. While symptomatic intracranial hemorrhage (sICH) has been well studied, the prognostic impact of asymptomatic intracranial hemorrhage (aICH) after EVT is less certain ...
