Stomatal opening ratio mediates trait coordinating network adaptation to environmental gradients
Siberian elm (Ulmus pumila) covariation eurybiont guard cells maximum theoretical stomatal conductance (gsmax) stomatal water availability
2023/11/28
A trait coordination network is constructed through intercorrelations of functional traits, which reflect trait-based adaptive strategies. However, little is known about how these networks change acro...

Channels of Small Log-Ratio Leakage and Characterization of Two-Party Differentially Private Computation
oblivious transfer differential privacy hardness amplification
2019/6/4
Consider a PPT two-party protocol Π=(A,B)Π=(A,B) in which the parties get no private inputs and obtain outputs OA,OB∈{0,1}OA,OB∈{0,1}, and let VAVA and VBVB denote the parties' individual views. Proto...
A Candidate Access Structure for Super-polynomial Lower Bound on Information Ratio
secret sharing general access structures information ratio
2019/6/3
The contribution vector (convec) of a secret sharing scheme is the vector of all share sizes divided by the secret size. A measure on the convec (e.g., its maximum or average) is considered as a crite...
Leakage-resilient Identity-based Encryption in Bounded Retrieval Model with Nearly Optimal Leakage-Ratio
Leakage-resilience Bounded retrieval model Identity-based Encryption
2019/1/26
We propose new constructions of leakage-resilient public-key encryption (PKE) and identity-based encryption (IBE) schemes in the bounded retrieval model (BRM). In the BRM, adversaries are allowed to o...

Hyperspectral remote sensing is a completely non-invasive technology for measurement of cultural relics, and has been successfully applied in identification and analysis of pigments of Chinese histori...
Information-Theoretic Secret-Key Agreement: The Secret-Key Rate as a Function of the Channel Quality Ratio
Secret-Key Agreement Information-theoretic security Satellite model
2017/11/28
Information theoretically secure secret-key exchange between two parties, Alice and Bob, is a well-studied problem that is provably impossible without additional assumptions. However, it has shown to ...
In a recent paper, Aggarwal, Joux, Prakash, and Santha (AJPS) describe an ingenious public-key cryptosystem mimicking NTRU over the integers. This algorithm relies on the properties of Mersenne primes...
Assessment of root-shoot ratio biomass and carbon storage of Quercus brantii Lindl. in the central Zagros forests of Iran
carbon sequestration crown diameter component Persian oak growth form
2018/3/6
Assessment of carbon storage build-up in tree stems is a difficult task due to the lack of information on their carbon
sequestration potential and allocation in different components. Similarly, high ...
