Cirrate octopods are considered to resemble the ancestor of all octopuses. Cirrates inhabit deep ocean and characterized by presence fins, a cartilaginous inner shell single row suckers alternating with pairs cirri thus comprising uniserial biserial cirri. The objective this contribution is improve taxonomy Opisthoteuthis bruuni from southeastern Pacific Ocean suggest new hypothesis cirrate phy...

It is shown that each almost maximal valuation ring R, such that every indecomposable injective R-module is countably generated, satisfies the following condition (C): each fp-injective R-module is locally injective. The converse holds if R is a domain. Moreover, it is proved that a valuation ring R that satisfies this condition (C) is almost maximal. The converse holds if Spec(R) is countable....

We introduce an algorithm for MinA extraction in EL based on bidirectional reachability. We obtain a significant reduction in the size of modules extracted at almost no additional cost to that of extracting standard reachability-based modules. Bidirectional modules are related to nested locality modules, but are aimed specifically at MinA extraction and are generally smaller. For acyclic EL TBo...

in this errata, we reconsider and modify two propositions and their corollaries which were written on epi-retractable and co-epi-retractable modules.
