Selectively Linkable and Convertible Ring Signature Scheme Based on DLP [PDF]

open access: yesJisuanji gongcheng, 2019
Most of the existing linkable and convertible ring signature schemes do not have strong anonymity.To solve this problem,a ring signature scheme based on Discrete Logarithm Problem(DLP) is proposed.The actual signer establishes an association tag by ...

Tumor‐Intrinsic Forkhead Box A2 Regulates the Lymph Node Metastasis of Papillary Thyroid Carcinoma by Regulating T‐Cell Apoptosis

open access: yesiLABMED, EarlyView.
We identified FOXA2 as a key regulator of lymph node metastasis in thyroid cancer, which controls cancer cell aggressiveness. FOXA2 knockdown promotes metastasis by enhancing tumor cell migration and, importantly, by inducing T‐cell apoptosis through a CCL2/LCN2‐mediated pathway. Created with BioGDP.com.

Security analysis and improvement of a certificateless signcryption scheme

open access: yesTongxin xuebao, 2015
To solve the certificate management problem in the traditional public key cryptography and the key escrow problem in the identity-based public key cryptography, Al-Riyami and Paterson proposed the concept of the certificateless public key cryptography ...

Permutation-Based Hash Chains with Application to Password Hashing

open access: yesIACR Transactions on Symmetric Cryptology
Hash 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.

Enhancing Study Design and Analysis of MR Imaging Markers Through Measurement Error Modeling

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Measurement error in imaging reduces statistical power and potentially biases parameter estimation, compromising study reliability. Purpose To introduce a dual data collection design (reliability and main datasets) to quantify measurement error and apply regression calibration to correct error‐prone imaging markers, thereby ...

Verifiable Random Functions (VRFs) [PDF]

open access: yes, 2018
A Verifiable Random Function (VRF) is the public-key version of a keyed cryptographic hash. Only the holder of the private key can compute the hash, but anyone with public key can verify the correctness of the hash.

Toward Explainable Engineering Decisions: Pursuing a Descriptive Decision Theory at the Intersection of Analysis, Judgment, and Conviction

open access: yesSystems Engineering, EarlyView.
ABSTRACT Engineers design the technical systems that define and sustain our society. The decision‐making scenarios they face require both quantitative analyses and the consideration of qualitative factors, which are shaped by deeply held beliefs, values, and societal contexts. However, existing engineering decision‐making models, primarily derived from

Empirical entropy, minimax regret and minimax risk

open access: yes, 2017
We consider the random design regression model with square loss. We propose a method that aggregates empirical minimizers (ERM) over appropriately chosen random subsets and reduces to ERM in the extreme case, and we establish sharp oracle inequalities ...

AUGURAL TERRITORIES: On the Prophetic Organizing of the Mid‐range

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract In this article I introduce the concept of augural territories to theorize the urbanism that emerged during pandemic lockdowns. I draw on ethnographic research in Madrid to examine how community‐based responses—including mutual aid networks, food pantries and neighbourhood associations—disrupted the spatial and temporal logics of territorial ...
