We present two stability results in this paper. We rst obtain suucient conn ditions for the continuity of optimal values and solutions of convex programs in general vector spaces, as well as some types of robustness of some sub-optimal solutions. We then use these results in order to establish a new result in stochastic dynamic control of discrete event systems (known as constrained Markov Deci...

Crystal structures of protein-ligand complexes are often used to infer biology and inform structure-based drug discovery. Hence, it is important to build accurate, reliable models of ligands that give confidence in the interpretation of the respective protein-ligand complex. This paper discusses key stages in the ligand-fitting process, including ligand binding-site identification, ligand descr...

Plastic intake by marine vertebrates has been widely reported, but information about its presence in continental waterfowl is scarce. Here we analyzed faeces of waterbirds species (European coot, Fulica atra, mallard, Anas platyrhynchos and shelduck, Tadorna tadorna) for plastic debris in five wetlands in Central Spain. We collected 89 faeces of shelduck distributed in four lakes, 43.8% of them...

Abstract Here we present the first cases of birds using artificial plants as nest material. We report our findings for common coot ( Fulica atra ) from Leiden, Netherlands, in 2019. This is population freshwater studied its use anthropogenic materials, and together with another same year, earliest case an entire bird plastic all nests. also used nesting material by birds, discuss implications t...

Avian vacuolar myelinopathy (AVM) was recognized in 1994 as a cause of wild bird mortality when 29 bald eagles (Haliaeetus leucocephalus) succumbed to the disease at DeGray Lake, Arkansas (USA). The cause of AVM and its source remain undetermined despite extensive diagnostic and research investigations. Two years later, when AVM killed 26 eagles in the same area in Arkansas, it became apparent ...

Hawai'I's coastal plain wetlands are inhabited by five endangered endemic waterbird species. These include the Hawaiian Coot ('alae ke'oke'o), Hawaiian Duck (koloa maoli), Hawaiian Stilt (ae'o), Hawaiian Gallinule (Moorhen) ('alae 'ula), and Hawaiian Goose (nēnē). All five species are categorized as being "conservation reliant." The current strategy to recover these endangered birds includes la...

Globally, billion of devices in heterogeneous networks are interconnected by the Internet Things (IoT). IoT applications require a centralized decision-making system due to failure-prone connectivity and high latency such system. Low-latency communications primary characteristic applications. Since usually have small payload sizes, reducing communication overhead is crucial improving energy eff...

This work considers broadcast protocols made of successive communication rounds in the linear cost model: the time needed to send a message of length L is deened as + LL. In this model, the communication time of any algorithm A is expressed as the sum R A + T A , where R A is the number of rounds and T A the transmission cost of the algorithm. In order to design an eecient algorithm realizing a...

The recent developments in smart cities pose major security issues for the Internet of Things (IoT) devices. These directly result from inappropriate management protocols and their implementation by IoT gadget developers. Cyber-attackers take advantage such gadgets’ vulnerabilities through various attacks as injection Distributed Denial Service (DDoS) attacks. In this background, Intrusion Dete...

Flaviviruses of the Japanese encephalitis virus (JEV) antigenic complex, including West Nile virus (WNV), are recognized as emerging and reemerging pathogens. Circulation of flaviviruses has been recently detected in different mosquito and vertebrate species in several European countries. A serosurvey study was carried out to evaluate the circulation of WNV and other flaviviruses of the JEV ant...
