Integrable matrix models in discrete space-time

SciPost Physics, 2020
We introduce a class of integrable dynamical systems of interacting classical matrix-valued fields propagating on a discrete space-time lattice, realized as many-body circuits built from elementary symplectic two-body maps.

Recurrent cancer‐associated ERBB4 mutations are transforming and confer resistance to targeted therapies

Molecular Oncology, EarlyView.
We show that the majority of the 18 analyzed recurrent cancer‐associated ERBB4 mutations are transforming. The most potent mutations are activating, co‐operate with other ERBB receptors, and are sensitive to pan‐ERBB inhibitors. Activating ERBB4 mutations also promote therapy resistance in EGFR‐mutant lung cancer.

D-instantons and Matrix Models

, 1999
We discuss the Matrix Model aspect of configurations saturating a fixed number of fermionic zero modes. This number is independent of the rank of the gauge group and the instanton number.

Peroxidasin enables melanoma immune escape by inhibiting natural killer cell cytotoxicity

Molecular Oncology, EarlyView.
Peroxidasin (PXDN) is secreted by melanoma cells and binds the NK cell receptor NKG2D, thereby suppressing NK cell activation and cytotoxicity. PXDN depletion restores NKG2D signaling and enables effective NK cell–mediated melanoma killing. These findings identify PXDN as a previously unrecognized immune evasion factor and a potential target to improve

Mortality rate estimation for eelgrass Zostera marina (Potamogetonaceae) using projections from Leslie matrices

Revista de Biología Tropical, 2008
The main goal of this study is to provide estimations of mean mortality rate of vegetative shoots of the seagrass Zostera marina in a meadow near Ensenada Baja California, using a technique that minimizes destructive sampling.

Vital rates and population trajectory of a declining eastern wild turkey population in southeastern Oklahoma

Wildlife Society Bulletin
The eastern wild turkey (Meleagris gallopavo silvestris; hereafter, wild turkey) is a culturally and economically important game species in North America, yet populations have shown apparent declines across their distribution. Oklahoma, USA, has not been

Matrix models for circular ensembles [PDF]

, 2004
We describe an ensemble of (sparse) random matrices whose eigenvalues follow the Gibbs distribution for n particles of the Coulomb gas on the unit circle at inverse temperature beta.

M-Theory of Matrix Models

, 2006
Small M-theories unify various models of a given family in the same way as the M-theory unifies a variety of superstring models. We consider this idea in application to the family of eigenvalue matrix models: their M-theory unifies various branches of ...

Crucial parameters for precise copy number variation detection in formalin‐fixed paraffin‐embedded solid cancer samples

Molecular Oncology, EarlyView.
This study shows that copy number variations (CNVs) can be reliably detected in formalin‐fixed paraffin‐embedded (FFPE) solid cancer samples using ultra‐low‐pass whole‐genome sequencing, provided that key (pre)‐analytical parameters are optimized.

Demography of marine birds in the Northeast Atlantic: Informed parameter values for population modelling

Ecological Solutions and Evidence
Matrix models are often used to assess and predict the impact of human activities on wild populations. These models require input values of demographic parameters, that is survival and fecundity. However, empirical estimates of these parameters are often
