Milnor operations and the generalized Chern character

open access: yes, 2007
We have shown that the n-th Morava K-theory K^*(X) for a CW-spectrum X with action of Morava stabilizer group G_n can be recovered from the system of some height-(n+1) cohomology groups E^*(Z) with G_{n+1}-action indexed by finite subspectra Z.

Essential-small submodules relative to an arbitrary submodule

open access: yesIOP Conference Series: Materials Science and Engineering, 2019
Abstract Let R be an arbitrary ring and T a submodule of an R-module M. A submodule N is said to be Te-small in M, if for each essential submodule X of M, T ⊆ N + X implies that T ⊆ X. In this work we study this mentioned notion which is a generalization of the essential-small submodules as well as the T-small submodule.

A Short‐Cut Design Approach to Evaluate Reboiler Designs in Vapor Recompression Scenarios

open access: yesChemie Ingenieur Technik, EarlyView.
A short‐cut model framework that incorporates mechanical vapor recompression (MVR) requirements into reboiler design is presented, which is particularly beneficial during early process development with limited data or initial feasibility assessments.

δ-Hollow Modules

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences, 2017
    Let R be a commutative ring with unity and M be a non zero unitary left R-module. M is called a hollow module if every proper submodule N of M is small (N ≪ M), i.e. N + W ≠ M for every proper submodule W in M.

Design and construction of a Cherenkov imager for charge measurement of nuclear cosmic rays

open access: yes, 2011
A proximity focusing Cherenkov imager called CHERCAM, has been built for the charge measurement of nuclear cosmic rays with the CREAM instrument. It consists of a silica aerogel radiator plane across from a detector plane equipped with 1,600 1" diameter ...

Predicting cervical cancer DNA methylation from genetic data using multivariate CMMP

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Epigenetic modifications link the environment to gene expression and play a crucial role in tumour development. DNA methylation, in particular, is gaining attention in cancer research, including cervical cancer, the focus of this study.

Cokernels of random matrices satisfy the Cohen-Lenstra heuristics [PDF]

open access: yes, 2013
Let A be an n by n random matrix with iid entries taken from the p-adic integers or Z/NZ. Then under mild non-degeneracy conditions the cokernel of A has a universal probability distribution.

Small Monoform Modules

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences, 2017
 Let R be a commutative ring with unity, let M be a left R-module. In this paper we introduce the concept small monoform module as a generalization of monoform module.
