Domain Knowledge Aids in Signal Disaggregation; the Example of the Cumulative Water Heater
Alexander Belikov, Guillaume Matheron, Johan Sassi
In this article we present an unsupervised low-frequency method aimed at detecting and disaggregating the power used by Cumulative Water Heaters (CWH) in residential homes. Our mod…
Bayesian model of electrical heating disaggregation
François Culière, Laetitia Leduc, Alexander Belikov
Adoption of smart meters is a major milestone on the path of European transition to smart energy. The residential sector in France represents 35\% of electricity consumpti…
Detecting signal from science:The structure of research communities and prior knowledge improves prediction of genetic regulatory experiments
Alexander V. Belikov, Andrey Rzhetsky, James Evans
The explosive growth of scientists, scientific journals, articles and findings in recent years exponentially increases the difficulty scientists face in navigating prior knowledge.…
Study of the very high energy gamma-ray spectrum from the Galactic Center and future prospects
Alexander V. Belikov, Emmanuel Moulin, Joseph Silk
Ground-based gamma ray observations of the Galactic Center region have revealed a high energy gamma ray source spatially coincident with the gravitational centroid of our Galaxy. T…
Diffuse Gamma Ray Background from Annihilating Dark Matter in Density Spikes around Supermassive Black Holes
Alexander Belikov, Joseph Silk
Dark matter annihilation is proportional to the square of the density and is especially efficient in places of highest concentration of dark matter, such as dark matter spikes. The…
Super-exponential cutoff as a probe of annihilating dark matter
Alexander V. Belikov, Joseph Silk
We investigate the possibility of fitting the putative spectrum of gamma-rays from annihilating dark matter at the Galactic Center by a super-exponential template. By generating an…
Equivalence Principle Violation in Weakly Vainshtein-Screened Systems
Alexander V. Belikov, Wayne Hu
Massive gravity, galileon and braneworld models that modify gravity to explain cosmic acceleration utilize the nonlinear field interactions of the Vainshtein mechanism to screen fi…
Neutron injection during primordial nucleosynthesis alleviates the primordial 7Li problem
Daniel Albornoz Vasquez, Alexander Belikov, Alain Coc +2
We present a parametrized study of the effects of free thermal neutron injection on primordial nucleosynthesis, where both the rate and the time scale of injection are varied. This…
Study of the Gamma-ray Spectrum from the Galactic Center in view of Multi-TeV Dark Matter Candidates
Alexander V. Belikov, Gabrijela Zaharijas, Joseph Silk
Motivated by the complex gamma-ray spectrum of the Galactic Center source now measured over five decades in energy, we revisit the issue of the role of dark matter annihilations in…
The Isotropic Radio Background and Annihilating Dark Matter
Dan Hooper, Alexander V. Belikov, Tesla E. Jeltema +3
Observations by ARCADE-2 and other telescopes sensitive to low frequency radiation have revealed the presence of an isotropic radio background with a hard spectral index. The inten…
Searching For Dark Matter Subhalos In the Fermi-LAT Second Source Catalog
Alexander V. Belikov, Dan Hooper, Matthew R. Buckley
The dark matter halo of the Milky Way is expected to contain an abundance of smaller subhalos. These subhalos can be dense and produce potentially observable fluxes of gamma rays.…
CoGeNT, DAMA, and Neutralino Dark Matter in the Next-To-Minimal Supersymmetric Standard Model
John F. Gunion, Alexander V. ~Belikov, Dan Hooper
We assess the extent to which the NMSSM can allow for light dark matter in the $2\gev\lsim \mcnone\lsim 12\gev$ mass range with correct relic density and large spin-independent dir…
CoGeNT, DAMA, and Light Neutralino Dark Matter
Alexander V. Belikov, John F. Gunion, Dan Hooper +1
Recent observations by the CoGeNT collaboration (as well as long standing observations by DAMA/LIBRA) suggest the presence of a -10 GeV dark matter particle with a somewhat…
No Indications of Axion-Like Particles From Fermi
Alexander V. Belikov, Lisa Goodenough, Dan Hooper
As very high energy (~100 GeV) gamma rays travel over cosmological distances, their flux is attenuated through interactions with the extragalactic background light. Observations of…
The Contribution Of Inverse Compton Scattering To The Diffuse Extragalactic Gamma-Ray Background From Annihilating Dark Matter
Alexander V. Belikov, Dan Hooper
In addition to gamma-rays, dark matter annihilation products can include energetic electrons which inverse Compton scatter with the cosmic microwave background to produce a diffuse…
How Dark Matter Reionized The Universe
Alexander V. Belikov, Dan Hooper
Although empirical evidence indicates that that the universe's gas had become ionized by redshift z ~ 6, the mechanism by which this transition occurred remains unclear. In this ar…
Identifying Dark Matter Annihilation Products In The Diffuse Gamma Ray Background
Scott Dodelson, Alexander V. Belikov, Dan Hooper +1
Annihilation of cosmologically distributed dark matter is predicted to produce a potentially observable flux of high energy photons. Neglecting the contribution from local structur…
Ground-state properties of a one-dimensional system of dipoles
A. S. Arkhipov, G. E. Astrakharchik, A. V. Belikov +1
A one-dimensional (1D) Bose system with dipole-dipole repulsion is studied at zero temperature by means of a Quantum Monte Carlo method. It is shown that in the limit of small line…
