Universality in snowflake aggregation [PDF]

open access: yes, 2003
Aggregation of ice crystals is a key process governing precipitation. Individual ice crystals exhibit considerable diversity of shape, and a wide range of physical processes could influence their aggregation; despite this we show that a simple computer ...

Practical issues of twin-field quantum key distribution

open access: yesNew Journal of Physics, 2019
Twin-field quantum key distribution(TF-QKD) protocol and its variants, such as phase-matching QKD, sending-or-not-sending QKD and no phase post-selection TF-QKD(NPP-TFQKD), are very promising for long-distance applications.

Sifting attacks in finite-size quantum key distribution

open access: yesNew Journal of Physics, 2016
A central assumption in quantum key distribution (QKD) is that Eve has no knowledge about which rounds will be used for parameter estimation or key distillation.

Estimating the size of key populations at higher risk of HIV infection: a summary of experiences and lessons presented during a technical meeting on size estimation among key populations in Asian countries

open access: yesWestern Pacific Surveillance and Response, 2014
Problem: Size estimates of key populations at higher risk of HIV exposure are recognized as critical for understanding the trajectory of the HIV epidemic and planning and monitoring an effective response, especially for countries with concentrated and ...

Cosmic Strings Collision in Cosmological Backgrounds [PDF]

open access: yes, 2010
The collisions of cosmic strings loops and the dynamics of junctions formations in expanding backgrounds are studied. The key parameter controlling the dynamics of junctions formation, the cosmic strings zipping and unzipping is the relative size of the ...

A Review of Block Ciphers and Its Post-Quantum Considerations

open access: yesIEEE Access
Recent advances in cryptography aim to address threats posed by quantum computers. However, these advances have focused disproportionately on asymmetric schemes, while symmetric primitives like block ciphers have received less attention.

Impact of Particle Size and Polydispersity Index on the Clinical Applications of Lipidic Nanocarrier Systems

open access: yesPharmaceutics, 2018
Lipid-based drug delivery systems, or lipidic carriers, are being extensively employed to enhance the bioavailability of poorly-soluble drugs. They have the ability to incorporate both lipophilic and hydrophilic molecules and protecting them against ...

It’s Not Just Size That Matters: Small Language Models Are Also Few-Shot Learners [PDF]

open access: yesNorth American Chapter of the Association for Computational Linguistics, 2020
When scaled to hundreds of billions of parameters, pretrained language models such as GPT-3 (Brown et al., 2020) achieve remarkable few-shot performance.
