Similar generalized frames [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2018
Generalized frames are an extension of frames in Hilbert  spaces and  Hilbert $C^*$-modules. In this paper, the concept ''Similar" for modular $g$-frames is introduced and all of operator duals (ordinary duals) of similar $g$-frames with respect to each ...

Contraction and uniform convergence of isotonic regression

open access: yes, 2018
We consider the problem of isotonic regression, where the underlying signal $x$ is assumed to satisfy a monotonicity constraint, that is, $x$ lies in the cone $\{ x\in\mathbb{R}^n : x_1 \leq \dots \leq x_n\}$.

PARP inhibitors elicit distinct transcriptional programs in homologous recombination competent castration‐resistant prostate cancer

open access: yesMolecular Oncology, EarlyView.
PARP inhibitors are used to treat a small subset of prostate cancer patients. These studies reveal that PARP1 activity and expression are different between European American and African American prostate cancer tissue samples. Additionally, different PARP inhibitors cause unique and overlapping transcriptional changes, notably, p53 pathway upregulation.

Two-Dimensional Hp-Adaptive Algorithm For Continuous Approximations Of Material Data Using Space Projection

open access: yesComputer Science, 2013
In this paper we utilize the concept of the L2 and H1 projections used toadaptively generate a continuous approximation of an input material data inthe finite element (FE) base.

Reverse Engineering Approach to Quantum Electrodynamics

open access: yes, 2013
The S matrix of e--e scattering has the structure of a projection operator that projects incoming separable product states onto entangled two-electron states.

Bridging the gap: Multi‐stakeholder perspectives of molecular diagnostics in oncology

open access: yesMolecular Oncology, EarlyView.
Although molecular diagnostics is transforming cancer care, implementing novel technologies remains challenging. This study identifies unmet needs and technology requirements through a two‐step stakeholder involvement. Liquid biopsies for monitoring applications and predictive biomarker testing emerge as key unmet needs. Technology requirements vary by

Projection operator techniques in Lagrangian mechanics: symmetrically coupled oscillators

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1980
We apply projection operator techniques to the computation of the natural frequencies of oscillation for three symmetrically coupled mechanical systems.

Multi-scale projection operator method and coarse-graining of covariant Fokker-Planck theory

open access: yesPhysical Review Research, 2023
A multi-scale projection operator method is developed and applied to study coarse-graining of covariant Fokker-Planck theory and the associated Ito-Langevin dynamics. Explicit expressions for the renormalized kinetic coefficients are obtained. It is also

Projective Truncation Approximation for Equations of Motion of Two-Time Green's Functions

open access: yes, 2018
In the equation of motion approach to the two-time Green's functions, conventional Tyablikov-type truncation of the chain of equations is rather arbitrary and apt to violate the analytical structure of Green's functions.

Adaptaquin is selectively toxic to glioma stem cells through disruption of iron and cholesterol metabolism

open access: yesMolecular Oncology, EarlyView.
Adaptaquin selectively kills glioma stem cells while sparing differentiated brain cells. Transcriptomic and proteomic analyses show Adaptaquin disrupts iron and cholesterol homeostasis, with iron chelation amplifying cytotoxicity via cholesterol depletion, mitochondrial dysfunction, and elevated reactive oxygen species.
