Journal of High Energy Physics, 2017 We investigate the consequences of a generalized ℤ 2 × ℤ 2 symmetry on a scaling neutrino Majorana mass matrix. It enables us to determine definite analytical relations between the mixing angles θ 12 and θ 13, maximal CP violation for the Dirac type and ...

European Journal of Biochemistry, 1997 Membrane-type-1 matrix metalloproteinase has been identified as an activator of the matrix metalloproteinase progelatinase A at cell surfaces. We report here that a soluble active form of membrane-type-2 matrix metalloproteinase can also process ...

An \~{O}$(n^2)$ Time Matrix Multiplication Algorithm
, 2020 We show, for the input vectors $(a_0, a_1, ..., a_{n-1})$ and $(b_0, b_1, ..., b_{n-1})$, where $a_i$'s and $b_j$'s are real numbers, after \~{O}$(n)$ time preprocessing for each of them, the vector multiplication $(a_0, a_1, ..., a_{n-1})(b_0, b_1, ...,

Precision study of 6p 2Pj - 8s 2S1/2 relative transition matrix elements in atomic Cs
, 2003 A combined experimental and theoretical study of transition matrix elements of the 6p 2Pj - 8s 2S1/2 transition in atomic Cs is reported. Measurements of the polarization-dependent two-photon excitation spectrum associated with the transition were made ...

The decomposition of an arbitrary $2^w\times 2^w$ unitary matrix into signed permutation matrices
, 2020 Birkhoff's theorem tells that any doubly stochastic matrix can be decomposed as a weighted sum of permutation matrices. A similar theorem reveals that any unitary matrix can be decomposed as a weighted sum of complex permutation matrices.

Transcriptome‐wide analysis of circRNA and RBP profiles and their molecular relevance for GBM
Molecular Oncology, EarlyView.CircRNAs are differentially expressed in glioblastoma primary tumors and might serve as therapeutic targets and diagnostic markers. The investigation of circRNA and RNA‐binding proteins (RBPs) interactions shows that distinct RBPs play a role in circRNA biogenesis and function.

BMC Musculoskeletal Disorders, 2010 Background Pain due to temporomandibular disorders (TMDs) often has the same clinical symptoms and signs as other types of orofacial pain (OP). The possible presence of serious neurological and/or systemic organic pathologies makes differential diagnosis

The border rank of the multiplication of 2×2 matrices is seven
, 2005 One of the leading problems of algebraic complexity theory is matrix multiplication. The naive multiplication of two n× n matrices uses n multiplications.

The universal R-matrix for the Jordanian deformation of sl(2), and the contracted forms of so(4)
, 1995 We introduce a universal R matrix for the Jordanian deformation of $\U{ \sl(2)}$. Using $\Uh{\so(4)}=\Uh{\sl(2)} \oplus {\rm U}_{-h}(\sl(2))$, we obtain the universal R matrix for $\Uh{\so(4)}$.

Molecular Oncology, EarlyView.Low expression of five purine metabolism‐related genes (ADSL, APRT, ADCY3, NME3, NME6) was correlated with poor survival in colorectal cancer. Immunohistochemistry analysis showed that low NME3 (early stage) and low ADSL/NME6 (late stage) levels were associated with high risk.
