Generation of neurons in the vertebrate central nervous system requires a complex transcriptional regulatory network and signaling processes in polarized neuroepithelial progenitor cells. Here we demonstrate that neurogenesis in the Xenopus neural plate in vivo and mammalian neural progenitors in vitro involves intrinsic antagonistic activities of the polarity proteins PAR-1 and aPKC. Furthermo...

This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in TCP/IP-based internets. In particular, it defines objects for managing remote network monitoring (RMON) devices for use on high speed networks. This document contains a MIB Module that defines these new objects and also contains definitions of some updated objects from the RMON-MIB ...

Status of this Memo This memo is an extension to the SNMP MIB. This RFC specifies an IAB standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "IAB Official Protocol Standards" for the standardization state and status of this protocol. Distribution of this memo is unlimited. 1. Abstract This memo...

BACKGROUND The natural history of surgically treated intracranial meningiomas can be quite variable. Recurrence and patient outcome cannot currently be predicted with accuracy. OBJECTIVE To explore the potential roles of tumor hypoxia-regulated biological markers, preoperative imaging, measures of proliferation, and angiogenesis in predicting patient outcome. METHODS Tissue from 263 patient...

BACKGROUND The 2016 WHO histopathological grading includes a substantial within-variation in recurrence risk, and is thus insufficient to predict prognosis after initial surgery of patients suffering from meningiomas. The aim of this study was to compare the prognostic value of the histopathological grading and the conventional biomarker MIB-1 with expression of the anti-apoptotic protein survi...

The Internet-standard management protocol SNMP manipulates data structures that are defined in MIB modules. A large number of MIB modules has been defined over the last decade. Some of them are rather complex and full of technical details, which makes it hard to understand them. Furthermore, the limitations of the current data definition language make it impossible to formally express the conce...

The joint Jasmin project of the Technical University of Braunschweig and NEC C&C Research Laboratories is concerned with the development, implementation and practical evaluation of the management by delegation architecture standardized by the Distributed Management (DISMAN) working group of the IETF. This paper presents the open source software components that have been developed during the pas...

This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it defines a basic set of managed objects for Simple Network Management Protocol (SNMP)-based management of Data Over Cable Service Interface Specification (DOCSIS)-compliant Cable Modems and Cable Modem Termination Systems. This memo obsoletes...

This paper reports the three-dimensional (3D) generalization of our previous 2D higher-order matched interface and boundary (MIB) method for solving elliptic equations with discontinuous coefficients and non-smooth interfaces. New MIB algorithms that make use of two sets of interface jump conditions are proposed to remove the critical acute angle constraint of our earlier MIB scheme for treatin...

1. Status of this Memo This memo defines an experimental portion of the Management Information Base (MIB) for use with network management protocols in TCP/IP-based internets. This memo does not specify a standard for the Internet community. However, after experimentation, if sufficient consensus is reached in the Internet community, then a subsequent revision of this document may be placed in t...
