Approximating a similarity matrix by a latent class model: A reappraisal of additive fuzzy clustering

, 2009
Let Q be a given n×n square symmetric matrix of nonnegative elements between 0 and 1, similarities. Fuzzy clustering results in fuzzy assignment of individuals to K clusters.

Site basis excitation Ansatz for matrix product states

SciPost Physics Core
We introduce a simple and efficient variation of the tangent-space excitation Ansatz used to compute elementary excitation spectra of one-dimensional quantum lattice systems using matrix product states (MPS).

The associations between dietary practices and dietary quality, biological health indicators, perceived stress, religiosity, culture, and gender in multicultural Singapore

Journal of Ethnic Foods, 2018
Background: Dietary quality, biological health, culture, religiosity, and perceived stress are co-related. However, there is a dearth of research conducted on Asian populations in secularized and harmonious multicultural societies.

Screening and epitope characterization of Nidogen‐2‐specific nanobodies

FEBS Open Bio, EarlyView.
Camel immunization and phage display were employed to generate high‐affinity VHH nanobodies against Nidogen‐2. After library construction, biopanning, ELISA screening, sequencing, and recombinant expression, selected nanobodies were purified and characterized, leading to the preliminary exploration of a nanobody‐based sandwich ELISA for specific ...

Products of commutators in matrix rings

Canadian Mathematical Bulletin
AbstractLet R be a ring and let $n\ge 2$ . We discuss the question of whether every element in the matrix ring $M_n(R)$ is a product of (additive) commutators $[x,y]=xy-yx$ , for $x,y\in M_n(R)$ . An example showing that this does not always hold, even when R is commutative, is provided.

Matrix-product codes over finite chain rings

, 2008
Tim Blackmore and Graham H. Norton introduced the notion of matrix-product codes over finite fields. The present paper provides a generalization to finite chain rings.

Continuous matrix-product operators for quantum fields

Physical Review Research
In this work, we introduce an ansatz for continuous matrix-product operators for quantum field theory. We show that (1) they admit a closed-form expression in terms of finite number of matrix-valued functions without reference to any lattice parameter ...

Matrix metalloproteinase‐9 regulates cell adhesion and membrane protrusive activity of ovarian cancer cells

FEBS Open Bio, EarlyView.
Matrix metalloproteinase‐9 (MMP9) drives ovarian cancer progression. Using MMP9‐null cells (M9‐KO) created from ovarian cancer cells, we found MMP9 loss did not block Epidermal Growth Factor (EGF)‐driven E‐cadherin dissolution or EMT but delayed and reduced EGF‐driven membrane protrusions. Transient MMP9 re‐expression drove membrane protrusion.

Thermoplastic matrix towpreg production

Advances in Polymer Technology, 2010
AbstractThis work was carried out to establish the processing window for the cost‐efficient production of thermoplastic matrix towpregs with a recently developed powder‐coating equipment. Three different fiber‐reinforced thermoplastic matrix systems were studied: one for highly demanding markets (carbon fiber/Primospire™) and other two for commercial ...
