Black hole entropy for the general area spectrum
, 2009 We consider the possibility that the horizon area is expressed by the general area spectrum in loop quantum gravity and calculate the black hole entropy by counting the degrees of freedom in spin-network states related to its area.

Energies, 2018 High penetration of wind power in the modern power system renders traditional automatic generation control (AGC) methods more challenging, due to the uncertainty of the external environment, less reserve power, and small inertia constant of the power ...

Is entanglement entropy proportional to area? [PDF]
, 2006 It is known that the entanglement entropy of a scalar field, found by tracing over its degrees of freedom inside a sphere of radius ${\cal R}$, is proportional to the area of the sphere (and not its volume).

Band Limited Signals Observed Over Finite Spatial and Temporal Windows: An Upper Bound to Signal Degrees of Freedom [PDF]
, 2014 The study of degrees of freedom of signals observed within spatially diverse broadband multipath fields is an area of ongoing investigation and has a wide range of applications, including characterising broadband MIMO and cooperative networks. However, a

Three years later: Italy and the free movement of new EU workers
Central European Public Administration Review, 2007 The freedom of movement of workers as one of the four main pillars of the EU can be defined as a neutral principle, which ensures its use in both the economic area for which it was created and also the social area.

Comments on the Entanglement Entropy on Fuzzy Spaces
, 2009 We locate the relevant degrees of freedom for the entanglement entropy on some 2+1 fuzzy models. It is found that the entropy is stored in the near boundary degrees of freedom.

Entropy of Reissner-Nordstrom Black Holes with Minimal Length Revisited
, 2007 Based on the generalized uncertainty principle, we study the entropy of a four-dimensional black hole by counting degrees of freedom near the horizon and obtain the (finite) entropy proportional to the surface area at the horizon without a cutoff ...

Democracy and Digital Authoritarianism: An Assessment of the EU’s External Engagement in the Promotion and Protection of Internet Freedom. College of Europe EU Diplomacy Paper 01/2020 [PDF]
, 2020 The past decade has seen a gradual global increase in digital authoritarianism. Internet shutdowns, online censorship, mass surveillance and violations of privacy rights have all become more frequent in parts of the world where citizens are not ...

Entanglement area law from specific heat capacity [PDF]
, 2015 We study the scaling of entanglement in low-energy states of quantum many-body models on lattices of arbitrary dimensions. We allow for unbounded Hamiltonians such that systems with bosonic degrees of freedom are included.

`Thermodynamics' of Minimal Surfaces and Entropic Origin of Gravity
, 2010 Deformations of minimal surfaces lying in constant time slices in static space-times are studied. An exact and universal formula for a change of the area of a minimal surface under shifts of nearby point-like particles is found.
