Seismic sensitivity to sub-surface solar activity from 18 years of GOLF/SoHO observations [PDF]
, 2015 Solar activity has significantly changed over the last two Schwabe cycles. After a long and deep minimum at the end of Cycle 23, the weaker activity of Cycle 24 contrasts with the previous cycles.

Multi-use unidirectional proxy re-signatures [PDF]
Proceedings of the 15th ACM conference on Computer and communications security, 2008 In 1998, Blaze, Bleumer, and Strauss suggested a cryptographic primitive named proxy re-signatures where a proxy turns a signature computed under Alice's secret key into one from Bob on the same message. The semi-trusted proxy does not learn either party's signing key and cannot sign arbitrary messages on behalf of Alice or Bob.

Aggressive prostate cancer is associated with pericyte dysfunction
Molecular Oncology, EarlyView.Tumor‐produced TGF‐β drives pericyte dysfunction in prostate cancer. This dysfunction is characterized by downregulation of some canonical pericyte markers (i.e., DES, CSPG4, and ACTA2) while maintaining the expression of others (i.e., PDGFRB, NOTCH3, and RGS5).

A Novel Anonymous Proxy Signature Scheme
Advances in Multimedia, 2012 Recently, several studies about proxy signature schemes have been conducted. In 2009, Yu et al. proposed an anonymous proxy signature scheme attempting to protect the proxy signer's privacy from outsiders.

A Strong Proxy Signature Scheme based on Partial Delegation [PDF]
, 2013 Proxy signature scheme is an extension of digital signature scheme first introduced by Mambo et al. in 1996, which allows a signer to delegate the signing capability to a designated person, called a proxy signer.

Molecular Oncology, EarlyView.Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

Forward secure proxy signature scheme
Tongxin xuebao, 2005 A forward secure proxy signature scheme was proposed combining the concept of forward security with proxy signature. This means even if an adversary has gotten the current proxy signers’ key.

Cryptanalysis of ID based Proxy-Blind signature scheme over lattice
ICT Express, 2020 In this article we review the ID Based Proxy-Blind signature scheme proposed by Zhang et al. and we give an attack on the scheme revealing the master secret key used in the construction of their scheme.

Time Stamped Proxy Blind Signature Scheme With Proxy Revocation Based on Discrete Logarithm Problem [PDF]
, 2013 Proxy blind signature combines both the properties of blind signature and proxy signature. In a proxy blind signature scheme, the proxy signer is allowed to generate a blind signature on behalf of the original signer.

Magnetic variability in the young solar analog KIC 10644253: Observations from the Kepler satellite and the HERMES spectrograph [PDF]
, 2016 The continuous photometric observations collected by the Kepler satellite over 4 years provide a whelm of data with an unequalled quantity and quality for the study of stellar evolution of more than 200000 stars.
