Coral Skeletons Defend against Ultraviolet Radiation
BACKGROUND Many coral reef organisms are photosynthetic or have evolved in tight symbiosis with photosynthetic symbionts. As such, the tissues of reef organisms are often exposed to intense solar radiation in clear tropical waters and have adapted to trap and harness photosynthetically active radiation (PAR). High levels of ultraviolet radiation (UVR) associated with sunlight, however, represen...
متن کاملDefend encryption systems against side- channel attacks
From its ancient origin as a tool for protecting sensitive wartime or espionage-related messages, cryptography has become a foundational building-block for securing the systems, protocols, and infrastructure that underpin our modern interconnected world. But the physical mechanisms used in performing encryption and decryption can leak information, making it possible to bypass this security. Pro...
متن کاملDivide, Denoise, and Defend against Adversarial Attacks
Deep neural networks, although shown to be a successful class of machine learning algorithms, are known to be extremely unstable to adversarial perturbations. Improving the robustness of neural networks against these attacks is important, especially for security-critical applications. To defend against such attacks, we propose dividing the input image into multiple patches, denoising each patch...
متن کاملA New Approach to Defend against Ddos
We propose a mechanism which combines the advantage of cryptographic client puzzle and hop count filtering as a countermeasure to spoofed DOS attack. Once the communication channel has been established then HCF starts its work wherein an Internet server can easily infer the hop-count information from the Time-to-Live (TTL) field of the IP header. Using a mapping between IP addresses and their h...
متن کاملAnts defend aphids against lethal disease.
Social insects defend their own colonies and some species also protect their mutualist partners. In mutualisms with aphids, ants typically feed on honeydew produced by aphids and, in turn guard and shelter aphid colonies from insect natural enemies. Here we report that Formica podzolica ants tending milkweed aphids, Aphis asclepiadis, protect aphid colonies from lethal fungal infections caused ...
