Large Universe Subset Predicate Encryption Based on Static Assumption (without Random Oracle)
Predicate Encryption Adaptive Security Standard Model
2018/12/11
In a recent work, Katz et al. (CANS'17) generalized the notion of Broadcast Encryption to define Subset Predicate Encryption (SPE) that emulates \emph{subset containment} predicate in the encrypted do...
Placing Conditional Disclosure of Secrets in the Communication Complexity Universe
information theoretic cryptography communication complexity
2018/12/3
In the Conditional Disclosure of Secrets (CDS) problem (Gertner et al., J. Comput. Syst. Sci., 2000) Alice and Bob, who hold nn-bit inputs xx and yy respectively, wish to release a common secret zz to...
Practical Attribute-Based Encryption: Traitor Tracing, Revocation, and Large Universe
Attribute-Based Encryption Traitor Tracing Revocation
2016/1/8
In Ciphertext-Policy Attribute-Based Encryption (CP-ABE), a user's decryption key is associated with attributes which in general are not related to the user's identity, and the same set of attributes ...
Efficient Statically-Secure Large-Universe Multi-Authority Attribute-Based Encryption
Attribute-Based Encryption Multi-Authority Large Universe
2016/1/5
We propose an efficient large-universe multi-authority ciphertext-policy attribute-based
encryption system. In a large-universe ABE scheme, any string can be used as an attribute of the system,
and ...
The Einstein universe is the conformal compactification of Minkowski space.
It also arises as the ideal boundary of anti-de Sitter space. The purpose of this article is
to develop the syntheti...

Virtual Language Observatory:the portal to the language resources and technology universe
Virtual Language Observatory language resources technology universe
2015/4/8
Over the years, the field of Language Resources and Technology (LRT) has developed a tremendous amount of resources and tools.However, there is no ready-to-use map that researchers could use to gain a...
I highlight results from Chandr observations of nearby galaxies, including the Milky Way. These observations have offered insights into old mysteries and indications of new high energy astrophysical p...
The clustering dipole of the local universe from the Two Micron All Sky Survey
galaxies clusters
2014/12/24
The unprecedented sky coverage and photometric uniformity of the Two Micron All Sky Survey (2MASS) provides a rich resource for investigating the galaxies populating the local universe. A full charact...
Galaxy clustering and galaxy bias in a Lambda CDM universe
formation large-scale structure of universe
2014/12/24
We investigate galaxy clustering and the correlations between galaxies and mass in the ΛCDM cosmological model (inflationary cold dark matter with Ωm = 0.4, ΩΛ = 0.6, h = 0.65, n = 0.95, and σ8 = 0.8)...
Observations of the Gas Reservoir Around a Star Forming Galaxy In The Early Universe
general individual (A1689)
2014/12/23
We present a high signal-to-noise spectrum of a bright galaxy at z = 4.9 in 14 h of integration on VLT FORS2. This galaxy is extremely bright, i850 = 23:10 0:01, and is strongly-lensed by the foregr...
Galaxies in a simulated Lambda CDM Universe - I. Cold mode and hot cores
cooling fl ows feedback cluster
2014/12/23
We study the formation of galaxies in a large volume (50 h−1 Mpc, 2 × 2883 particles) cosmological simulation, evolved using the entropy and energy-conserving smoothed particle hydrodynamics (SP...
Galaxies in a simulated Lambda CDM universe - II. Observable properties and constraints on feedback
feedback cluster
2014/12/23
We compare the properties of galaxies that form in a cosmological simulation without strong feedback to observations of the z= 0 galaxy population. We confirm previous findings that models without str...
A Systematic Study of the Stellar Populations and ISM in Galaxies out to the Virgo Cluster: near field cosmology within a representative slice of the local universe
feedback near-fi eld cosmology
2014/12/22
We present a compelling case for a systematic and comprehensive study of the resolved and unresolved stellar populations, ISM, and immediate environments of galaxies throughout the local volume, defin...
OBSERVATIONS OF STARBURST GALAXIES WITH FAR-ULTRAVIOLET SPECTROGRAPHIC EXPLORER: GALACTIC FEEDBACK IN THE LOCAL UNIVERSE
starburst halos
2014/12/22
We have analyzed FUSE (905-1187 ? spectra of a sample of 16 local starburst galaxies. These galaxies cover almost three orders of magnitude in star-formation rates and over two orders of magnitude in ...
