Finitistic dimension and restricted injective dimension [PDF]

open access: yesCzechoslovak Mathematical Journal, 2015
Let \(R\) be a ring and \(T\) a left \(R\)-module with \(A := \text{End}_{R}(T)\). Then \(T\) can be viewed as a right \(A\)-module. The restricted injective dimension, \(\text{rid}\,(T_{A})\), of \(T_{A}\) is defined as the supremum of the natural numbers \(m\) such that \(\text{Ext}^{m}_{A}(Q, T_{A}) \neq 0\) for some finitely generated projective ...

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Real-time distributed systems dimensioning and validation: The TURTLE method [PDF]

open access: yes, 2010
The TURTLE language and toolkit offer a UML framework for service description, protocol modeling and communication architecture validation. The method associated with TURTLE uses an architectural design pattern where two or several protocol entities rely

Standards for the Dimensioning and Assessment of Reliable Operations of Area Drainage Systems under Conditions of Climate Change

open access: yesTechnical Transactions, 2018
Contemporary area drainage dimensioning standards are presented in this paper. Hazards for drainage systems arising from climate changes are discussed and trends of changes in the precipitation structure are presented using the example of data obtained ...

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Lightweight link dimensioning using sFlow sampling [PDF]

open access: yes, 2013
Operators use link dimensioning to provision network links. In practice, traffic averages are obtained via SNMP are used to roughly estimate required capacity. More accurate solutions often require traffic statistics easily obtained from packet captures,

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Dimensioning resilient optical grids

open access: yes, 2009
An important problem in optical networking is to dimension the network: given the amount of traffic to carry, determine the required amount of network resources (wavelengths).

Methodology for dimensioning the hoisting shaft using mathematical and graphical methods [PDF]

open access: yesPodzemni Radovi
The opening of deep ore bodies is most rapidly accomplished using vertical shafts. Shaft construction is the most economically demanding process, so despite providing the fastest access to deep ore bodies, the high capital costs involved in construction ...

Spherical dimension

open access: yesCoRR
We introduce and study the spherical dimension, a natural topological relaxation of the VC dimension that unifies several results in learning theory where topology plays a key role in the proofs. The spherical dimension is defined by extending the set of realizable datasets (used to define the VC dimension) to the continuous space of realizable ...
