Differentiable Randers‐Finsler Eikonal Solvers
Computer Graphics Forum, EarlyView.Abstract Fast and differentiable solvers for anisotropic and asymmetric distance fields are a key primitive in geometry processing, enabling gradient‐based optimization over metrics, drift fields, and downstream objectives that depend on geodesic distances and geodesics.

Certificateless signature scheme without bilinear pairings
Tongxin xuebao, 2012 To solve the key escrow problem inherited in ID-based cryptography and the complex certificate management problem of traditional certification-based public key cryptosystem,Al-Riyami and Paterson proposed the novel concept of certificateless public key ...

Permutation-Based Hash Chains with Application to Password Hashing
IACR Transactions on Symmetric CryptologyHash chain based password systems are a useful way to guarantee authentication with one-time passwords. The core idea dates back to Lamport, and is specified in RFC 1760 as S/Key. At CCS 2017, Kogan et al.

The Random Oracle Methodology, Revisited [PDF]
, 2003 We take a critical look at the relationship between the security of cryptographic schemes in the Random Oracle Model, and the security of the schemes that result from implementing the random oracle by so called cryptographic hash functions .

Shareholder Activism: Affliction for Incumbent CEOs?
Financial Management, EarlyView.ABSTRACT We study how shareholder activism shapes CEO careers by distinguishing between two competing hypotheses: discipline and reallocation. Employing a control function approach with expected mutual fund fire sales and purchases as exclusion restrictions, we analyze 3799 US campaigns from 2006 to 2018.

International Statistical Review, EarlyView.Summary In high‐dimensional survival analysis, effective variable selection is crucial both for model interpretation and predictive performance. This paper investigates Cox regression with lasso and adaptive lasso penalties in genomic datasets where covariates far outnumber observations.

Improved identity based multi-receiver anonymous signcryption scheme
Tongxin xuebao, 2015 Recently,Pang,et al proposed a novel identity based multi-receiver anonymous signcryption scheme (IBMRASC),which put into consideration both the sender's anonymity and the receiver's anonymity simultaneously.However,the analysis with respect to this ...

International Transactions in Operational Research, EarlyView.Abstract This work aims at minimizing the energy purchase costs related to the operation of a green hydrogen production plant connected both to an intermittent, uncertain renewable energy source and to the power grid. We focus on scenarios where, for economic or environmental reasons, the plant must primarily meet hydrogen demand using electricity from
