Weak $A$-frames and weak $A$-semi-frames [PDF]
Constructive Mathematical Analysis, 2021 After reviewing the interplay between frames and lower semi-frames, we introduce the notion of lower semi-frame controlled by a densely defined operator $A$ or, for short, a weak lower $A$-semi-frame and we study its properties. In particular, we compare it with that of lower atomic systems, introduced in (GB).

Journal of Mathematical Analysis and Applications, 2005 In this paper we give new characterizations of Riesz and conditional Riesz frames in terms of the properties of the nullspace of their synthesis operators. On the other hand, we also study the oblique dual frames whose coefficients in the reconstruction formula minimize different weighted norms.

Compare and contrast between duals of fusion and discrete frames [PDF]
arXiv, 2016 Fusion frames are valuable generalizations of discrete frames. Most concepts of fusion frames are shared by discrete frames. However, the dual setting is so complicated. In particular, unlike discrete frames, two fusion frames are not dual of each other in general.

M-LVC: Multiple Frames Prediction for Learned Video Compression [PDF]
Computer Vision and Pattern Recognition, 2020 We propose an end-to-end learned video compression scheme for low-latency scenarios. Previous methods are limited in using the previous one frame as reference. Our method introduces the usage of the previous multiple frames as references.

Super SloMo: High Quality Estimation of Multiple Intermediate Frames for Video Interpolation [PDF]
2018 IEEE/CVF Conference on Computer Vision and Pattern Recognition, 2017 Given two consecutive frames, video interpolation aims at generating intermediate frame(s) to form both spatially and temporally coherent video sequences.

Social Bias Frames: Reasoning about Social and Power Implications of Language [PDF]
Annual Meeting of the Association for Computational Linguistics, 2019 Warning: this paper contains content that may be offensive or upsetting. Language has the power to reinforce stereotypes and project social biases onto others.

Pervasive functional translation of noncanonical human open reading frames
Science, 2020 Expanding the human proteome Using mass spectrometry, ribosome profiling, and several CRISPR-based screens, Chen et al. identified hundreds of previously uncharacterized functional micropeptides in the human genome (see the Perspective by Wei and Guo ...

Frame Potentials and the Geometry of Frames [PDF]
Journal of Fourier Analysis and Applications, 2015 This paper concerns the geometric structure of optimizers for frame potentials. We consider finite, real or complex frames and rotation or unitarily invariant potentials, and mostly specialize to Parseval frames, meaning the frame potential to be optimized is a function on the manifold of Gram matrices belonging to finite Parseval frames.

G-frames and G-Riesz Bases [PDF]
, 2005 G-frames are generalized frames which include ordinary frames, bounded invertible linear operators, as well as many recent generalizations of frames, e.g., bounded quasi-projectors and frames of subspaces.
