Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization
Molecular Oncology, EarlyView.In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

Tight Reference Frame–Independent Quantum Teleportation [PDF]
Electronic Proceedings in Theoretical Computer Science, 2017 We give a tight scheme for teleporting a quantum state between two parties whose reference frames are misaligned by an action of a finite symmetry group.

Kirkman Equiangular Tight Frames and Codes [PDF]
IEEE Transactions on Information Theory, 2014 An equiangular tight frame (ETF) is a set of unit vectors in a Euclidean space whose coherence is as small as possible, equaling the Welch bound. Also known as Welch-bound-equality sequences, such frames arise in various applications, such as waveform design and compressed sensing.

Molecular Oncology, EarlyView.Drug resistance limits treatment success in a subset of lung cancers driven by ROS1 gene alterations. Using patient‐derived cells and computer simulations, we studied three key mutations and how they affect five targeted drugs. The mutations reduced drug effectiveness in different ways by altering protein structure and behavior.

Construction of Periodic Wavelet Frames Generated by the Walsh Polynomials
Mathematics, 2015 An explicit method for the construction of a tight wavelet frame generated by the Walsh polynomials with the help of extension principles was presented by Shah (Shah, 2013).

Translating whole‐genome doubling into precision medicine in cancer
Molecular Oncology, EarlyView.Whole‐genome doubling creates a WGD‐positive tumor state characterized by persistent chromosomal instability, karyotypic diversification, and cellular stress. These same biological pressures drive aggressive tumor evolution while exposing therapeutic vulnerabilities, providing a rationale for WGD‐informed precision medicine. Whole‐genome doubling (WGD)

The Electronic Journal of Linear Algebra, 2002 Summary: A \(d\times n\) matrix, \(n\geq d\), whose columns have equal length and whose rows are orthonormal is constructed. This is equivalent to finding an isometric tight frame of \(n\) vectors in \(\mathbb{R}^d\) (or \(\mathbb{C}^d\)), or writing the \(d\times d\) identity matrix \(I= {d\over n} \sum^n_{i=1} P_i\), where the \(P_i\) are rank 1 ...

PANoptosis in the pathogenesis of myelodysplastic syndromes
Molecular Oncology, EarlyView.PANoptosis, a combination of three types of programmed cell death, is mediated by a large protein complex called a PANoptosome. In healthy bone marrow hematopoietic cells, PANoptosis is restricted by inhibitory signaling. In MDS, bone marrow cells become sensitive to the PANoptotic stimuli due to the aberrant inactivation of inhibitory signaling or ...

Gabor systems on positive half line via Walsh-Fourier transform
Karpatsʹkì Matematičnì Publìkacìï, 2020 Gabor systems play a vital role not only in modern harmonic analysis but also in several fields of applied mathematics, for instances, detection of chirps, or image processing.
