State Space Collapse in Many-Server Diffusion Limits of Parallel Server Systems [PDF]
We consider a class of queueing systems that consist of server pools in parallel and multiple customer classes. Customer service times are assumed to be exponentially distributed. We study the asymptotic behavior of these queueing systems in a heavy traffic regime that is known as the Halfin-Whitt many-server asymptotic regime. Our main contribution is

Beyond the Territorial Trap?: The Geographic Interrogation of Sovereignty
Sovereignty is now a key concept in geographic scholarship. However, sustained geographic investigation of sovereignty commenced only in the 1990s, after the collapse of the Cold War order.

Uneven transformations: Space, economy and society 20 years after the collapse of state socialism [PDF]
Writing about the social and political revolts of 1968, Umberto Eco argued that one of the dominant narratives used in interpreting the impact of these events suggests that ‘[e]ven though all visible traces are gone ... it profoundly changed all of us’ (Newsweek, 22 December 1986: 49; quoted in Watts, 2001). Twenty years after the equally, if not more,

EXPERIMENTAL TESTS OF CONCRETE MEANS OF PROTECTION FOR COAL MINES DISTRICT ROADWAYS [PDF]
The current paper is devoted to experimental tests of working protection means in the construction of which concrete in liquid state is used. Such means of protection are most vulnerable to irreversible deformations during the period of their hardening ...

Latent space unsupervised semantic segmentation
The development of compact and energy-efficient wearable sensors has led to an increase in the availability of biosignals. To effectively and efficiently analyze continuously recorded and multidimensional time series at scale, the ability to perform ...

Dynamic control of Brownian networks: state space collapse and equivalent workload formulations
Brownian networks are heavy traffic limits or heavy traffic approximations of queueing network processes or interconnected inventory system processes. The stochastic behaviour of such processes is determined by a multidimensional Brownian motion input process and a control process.

On the measurement problem for a two-level quantum system [PDF]
A geometric approach to quantum mechanics with unitary evolution and non-unitary collapse processes is developed. In this approach the Schrodinger evolution of a quantum system is a geodesic motion on the space of states of the system furnished with an ...

A Quantum-Like Model of Information Processing in the Brain
We present the quantum-like model of information processing by the brain’s neural networks. The model does not refer to genuine quantum processes in the brain.

The study of gravitational collapse model in higher dimensional space-time
We investigate the end state of the gravitational collapse of an inhomogeneous dust cloud in higher dimensional space-time. The naked singularities are shown to be developing as the final outcome of non-marginally bound collapse.

Flexible Load Balancing with Multi-dimensional State-space Collapse
Heavy traffic delay analysis for load balancing policies has relied heavily on a condition called state-space collapse onto a single-dimensional line. In this paper, via Lyapunov driftbased method, we rigorously prove that even under a multidimensional state-space collapse, steady-state heavy-traffic delay optimality can still be achieved for a general
