Water pricing and markets: Principles, practices and proposals
Applied Economic Perspectives and Policy, EarlyView.Abstract The allocation of water across space and time is a key challenge of water governance, with demand and supply often not well matched over time and place. Best practice water pricing and markets may promote water conservation, yet their application is limited.

Breaking the Hidden Irreducible Polynomials Scheme [PDF]
arXiv, 2019 In 2019 G\'omez described a new public key cryptography scheme based on ideas from multivariate public key cryptography using hidden irreducible polynomials. We show that the scheme's design has a flaw which lets an attacker recover the private key directly from the public key.

Private Domain Adaptation from a Public Source [PDF]
arXiv, 2022 A key problem in a variety of applications is that of domain adaptation from a public source domain, for which a relatively large amount of labeled data with no privacy constraints is at one's disposal, to a private target domain, for which a private sample is available with very few or no labeled data.

Mexican consumers' attitudes toward irradiated and imported apples
Agribusiness, EarlyView.Abstract This study centers on analyzing Mexican consumers' willingness to pay (WTP) for imported US fresh apples subjected to irradiation, contrasting it with the more prevalent postharvest chemical treatments. We collect data using a survey tool in Qualtrics designed to explore the impact of information dissemination through two distinct narrative ...

Security Algorithms for Cloud Computing Environment [PDF]
arXiv, 2015 In symmetric key cryptography the sender as well as the receiver possess a common key. Asymmetric key cryptography involves generation of two distinct keys which are used for encryption and decryption correspondingly. The sender converts the original message to cipher text using the public key while the receiver can decipher this using his private key.

Fourier domain asymmetric cryptosystem for privacy protected multimodal biometric security [PDF]
, 2018 We propose a Fourier domain asymmetric cryptosystem for multimodal biometric security. One modality of biometrics (such as face) is used as the plaintext, which is encrypted by another modality of biometrics (such as fingerprint). A private key is synthesized from the encrypted biometric signature by complex spatial Fourier processing.

Product differentiation in the fruit industry: Lessons from trademarked apples
Agribusiness, EarlyView.Abstract We derive price premiums for patented or trademarked apple varieties, also known as “club apples,” compared to open‐variety apples. We use an expansive retail scanner dataset, along with unique data on apple taste characteristics, to estimate monthly club apple premiums for 2008–2018.

Analytical Study of Hybrid Techniques for Image Encryption and Decryption
Sensors, 2020 The majority of imaging techniques use symmetric and asymmetric cryptography algorithms to encrypt digital media. Most of the research works contributed in the literature focus primarily on the Advanced Encryption Standard (AES) algorithm for encryption ...
