Journal of Mathematical Analysis and Applications, 1988 Let X be a Banach space. An operator T on X is called a Gellar basis shift if there is a scalar sequence \(\{W_ n\}\) and a normalized basis \(\{x_ n\}\) of X such that \(Tx_ n=w_ nx_{n+1}\). In this case, we say that the basis \(\{x_ n\}\) is Gellar shiftable by T. An operator T on X is said to be a Crownover shift if T is injective, has closed range,

Next‐generation proteomics improves lung cancer risk prediction
Molecular Oncology, EarlyView.This is one of very few studies that used prediagnostic blood samples from participants of two large population‐based cohorts. We identified, evaluated, and validated an innovative protein marker model that outperformed an established risk prediction model and criteria employed by low‐dose computed tomography in lung cancer screening trials.

Nabla derivatives associated with nonlinear control systems on homogeneous time scales
Nonlinear Analysis, 2016 The backward shift and nabla derivative operators, defined by the control system on homogeneous time scale, in vector spaces of one-forms and vector fields are introduced and some of their properties are proven.

THE OPERATOR SHIFT SPACE [PDF]
Proceedings of the Edinburgh Mathematical Society, 2008 AbstractWe construct and examine an operator space $X$, isometric to $\ell_2$, such that every completely bounded map from its subspace $Y$ into $X$ is a compact perturbation of a linear combination of multiples of a shift of given multiplicity and their adjoints. Moreover, every completely bounded map on $X$ is a Hilbert–Schmidt perturbation of such a

Potential therapeutic targeting of BKCa channels in glioblastoma treatment
Molecular Oncology, EarlyView.This review summarizes current insights into the role of BKCa and mitoBKCa channels in glioblastoma biology, their potential classification as oncochannels, and the emerging pharmacological strategies targeting these channels, emphasizing the translational challenges in developing BKCa‐directed therapies for glioblastoma treatment.

Molecular Oncology, EarlyView.The cancer problem is increasing globally with projections up to the year 2050 showing unfavourable outcomes in terms of incidence and cancer‐related deaths. The main challenges are prevention, improved therapeutics resulting in increased cure rates and enhanced health‐related quality of life.

On the Complete Indeterminacy and the Chaoticity of the Generalized Heun Operator in Bargmann Space
AxiomsIn 1998, we gave a complete scattering analysis of the cubic Heun operator H=a∗(a+a∗)a acting on Bargmann space, where a and a∗ are the standard Bose annihilation and creation operators satisfying the commutation relation [a,a∗]=I.

Molecular Oncology, EarlyView.Pharmacologic ascorbate (vitamin C) increases ROS, disrupts cellular metabolism, and induces DNA damage in CRPC cells. These effects sensitize tumors to PARP inhibition, producing synergistic growth suppression with olaparib in vitro and significantly delayed tumor progression in vivo. Pyruvate rescue confirms ROS‐dependent activity.

LDAcoop: Integrating non‐linear population dynamics into the analysis of clonogenic growth in vitro
Molecular Oncology, EarlyView.Limiting dilution assays (LDAs) quantify clonogenic growth by seeding serial dilutions of cells and scoring wells for colony formation. The fraction of negative wells is plotted against cells seeded and analyzed using the non‐linear modeling of LDAcoop.
