Classification of SPN Structures From the Viewpoint of Structural Cryptanalysis

open access: yesIEEE Access, 2018
In this paper, we provide two types of pattern matrices for the diffusion layer P, both can be used as classification criteria for the substitution-permutation network (SPN) structures: if the pattern matrices of distinct SPN structures are equal, then ...

Completions of partial P-matrices with acyclic or non-acyclic associated graph

open access: yesLinear Algebra and its Applications, 2003
The paper deals with the partial \(P\)-matrix completion problem, that is when a partial \(P\)-matrix \(A\) has a \(P\)-matrix completion \(A_c\). The first result asserts that every positive (sign-symmetric) partial \(P\)-matrix \(A\) has a positive (sign-symmetric) \(P\)-matrix completion when the associated graph of the specified entries is acyclic.

CD47 promotes mitogen‐activated protein kinase and epithelial‐to‐mesenchymal transition molecular programs to drive prometastatic phenotypes in non‐small cell lung cancer

open access: yesMolecular Oncology, EarlyView.
Beyond its role in immune evasion, this study identified that CD47 drives tumor‐intrinsic signaling in non‐small cell lung cancer (NSCLC). Transcriptomic profiling and functional studies revealed that CD47 regulates cell adhesion, migration, and metastasis through an ERK–EMT signaling axis.

On skew-Hadamard matrices

open access: yes, 2008
Skew-Hadamard matrices are of special interest due to their use, among others, in constructing orthogonal designs. In this paper, we give a survey on the existence and equivalence of skew-Hadamard matrices.

Optimizing substitution matrix choice and gap parameters for sequence alignment

open access: yesBMC Bioinformatics, 2009
Background While substitution matrices can readily be computed from reference alignments, it is challenging to compute optimal or approximately optimal gap penalties.

Adaptor protein CIN85 potentiates the motility of osteosarcoma cells via the Akt/mTOR and MMP2‐COL3A1 axis

open access: yesMolecular Oncology, EarlyView.
CIN85 is highly expressed in osteosarcoma, particularly in metastatic lesions. Its overexpression increases cell migration and Matrigel invasion, while silencing CIN85 suppresses these behaviors. Transcriptome analysis shows that CIN85 regulates MMP2, COL3A1, and Akt/mTOR signaling. Targeting these pathways reverses CIN85‐induced motility, highlighting

Interaction of HS1BP3 with cortactin modulates TKS5 localisation, cell secretion and cancer malignancy

open access: yesMolecular Oncology, EarlyView.
Here, we demonstrate that HS1BP3 interacts with Cortactin through a proline‐rich region (PRR3.1) and show that this interaction, and HS1BP3 itself, promote cancer cell proliferation and invasion. Inhibition of this interaction leads to build‐up of TKS5 in multivesicular endosomes and altered secretion of CD63 and CD9, providing an explanation for the ...

A note on optimal block-scaling of matrices

open access: yes, 1984
Elsner L. A note on optimal block-scaling of matrices. Numerische Mathematik. 1984;44(1):127-128.After pointing out that two recent results on optimal blockscaling are equivalent, a new short and simple proof of both results is ...

Optimal neighborhood indexing for protein similarity search

open access: yesBMC Bioinformatics, 2008
Background Similarity inference, one of the main bioinformatics tasks, has to face an exponential growth of the biological data. A classical approach used to cope with this data flow involves heuristics with large seed indexes.
