A matrix-geometric solution for the multiserver nonpreemptive priority queueing model with mixed priorities. [PDF]
This paper describes the analysis of multiserver queues with nonpreemptive mixed priorities. Such priority structures occur, for example, in initiator settings within the mainframe operating system MVS: job classes have to be assigned to initiators and ...

Resolving the Structural Duality of Graphene Grain Boundaries
Advanced Materials, EarlyView.Cantilever ncAFM resolves the atomic structure of grain boundaries in graphene, revealing coexisting stable and metastable types. Both contain pentagon/heptagon defects, but metastable GBs show irregular geometries. Modeling shows metastable GBs form under compression, exhibiting vertical corrugation, while stable GBs are flat.

Flat Committed Join in Join 1 [PDF]
, 2008 Committed Join (cJoin) is an extension of Join with high-level primitives for programming dynamic nested negotiations with compensations. In this paper we show that flat cJoin processes (i.e. processes without sub-negotiations) can be encoded in ordinary

Exo1 processes stalled replication forks and counteracts fork reversal in checkpoint-defective cells [PDF]
, 2005 The replication checkpoint coordinates the cell cycle with DNA replication and recombination, preventing genome instability and cancer. The budding yeast Rad53 checkpoint kinase stabilizes stalled forks and replisome-fork complexes, thus preventing the ...

Direct observation of stalled fork restart via fork regression in the T4 replication system [PDF]
, 2019 The restart of a stalled replication fork is a major challenge for DNA replication. Depending on the nature of the damage, different repair processes might be triggered; one is template switching, which is a bypass of a leading-strand lesion via fork ...

Advanced Materials, EarlyView.Ordered three‐dimensional anodic aluminum oxide (3D‐AAO) nanoarchitectures with longitudinal and transverse pores enable architecture‐driven metamaterials. The review maps fabrication advances, including hybrid pulse anodization, and shows how 3D‐AAO templates tailor properties across magnetism, energy, catalysis, and sensing.

Advanced Materials, EarlyView.Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including

Advanced Materials, EarlyView.Ionic epoxy networks are prepared using ammonium salts as hardeners, leading to a two‐stage curing process with a thermoplastic‐like intermediate. This uncommon behavior enables extrusion and fabrication of thermoplastic prepregs that can be cured into thermoset composites.

Observations of snowpack properties to evaluate ground-based microwave remote sensing [PDF]
, 2010 Active microwave radar has been shown to have great potential for estimating snow water equivalent (SWE) globally from space. To help evaluate optimal active microwave sensor configurations to observe SWE, we evaluated ground-based Frequency Modulated ...
