We report the isolation of mouse cerberus-like (cer-l), a gene encoding a novel secreted protein that is specifically expressed in the anterior visceral endoderm during early gastrulation. Expression in the primitive endoderm starts before the appearance of the primitive streak and lasts until the head-fold stage. In later stages, a second region of expression is found in newly formed somites. ...

Ecosystems transition quickly in the Anthropocene, whereas biodiversity adapts more slowly. Here we simulated a shifting woodland ecosystem on the Colorado Plateau of western North America by using as its proxy over space and time the fundamental niche of the Arizona black rattlesnake (Crotalus cerberus). We found an expansive (= end-of-Pleistocene) range that contracted sharply (= present), bu...

[1] Previous studies noted the close association of geologically very recent lava flows and fluvial channels emanating from Cerberus Fossae. To assess these relationships, we outline a model of magmatic dike emplacement that involves 1) surface fractures and localized volcanic eruptions, 2) attendant cryospheric cracking to fracture the surface and release pressurized groundwater confined benea...

Abstract Securing distributed device communication is critical because the private industry and military depend on these resources. One area that adversaries target middleware, which medium connects different systems. This paper evaluates a novel security layer, DDS-Cerberus (DDS-C), protects in-transit data improves efficiency data-first distribution research contributes robotics operating sys...

Introduction: The upper crust of Mars is layered and geologically diverse. Burial and exhumation complicate the use of impact craters to determine the age of materials. Since September 1997, we have employed the Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) to test hypotheses regarding the nature of the layered crust [1, 2]. Here we summarize key observations and update earlier findings,...

This paper presents Cerberus, an eÆcient system for simulating the execution of shared-memory multiprocessor programs on a uniprocessor workstation. Using EDS (execution driven simulation), it generates address traces which can be used to drive cache simulations on the y, eliminating the large disk space requirements needed by trace les. It is fast because it links the program to be traced toge...

Cerberus is a tool to automatically synthesize run-time enforcement mechanisms for security-sensitive Business Processes (BPs). The tool is capable of guaranteeing that the execution constraints EC on the tasks together with the authorization policy AP and the authorization constraints AC are satisfied while ensuring that the process can successfully terminate. Cerberus can be easily integrated...
