Population Ecology, EarlyView.We investigate the seasonal dynamics of two freshwater snails, Biomphalaria straminea and Melanoides tuberculata, in artificial reservoirs of the Brazilian semiarid region. Despite regulated hydrology, B. straminea exhibited strong seasonal fluctuations associated with dry periods, while M. tuberculata maintained stable populations throughout the year,

Improved Related-Cipher Attack on Salsa20 Stream Cipher
IEEE Access, 2019 The Salsa20 stream cipher was designed by Bernstein in 2005 as a candidate for eSTREAM and Salsa20/12 was accepted in the eSTREAM software portfolio in 2008. In this paper, we present an improved related-cipher attack on Salsa20.

A New Guess-and-Determine Attack on the A5/1 Stream Cipher [PDF]
, 2012 In Europe and North America, the most widely used stream cipher to ensure privacy and confidentiality of conversations in GSM mobile phones is the A5/1. In this paper, we present a new attack on the A5/1 stream cipher with an average time complexity of 2^

Electronics Letters, 1992 The chaotic Henon mapping has been proposed as a method of generating a binary sequence, the Henon sequence. Here it is proven that the subsequence 1100 never occurs in the Henon sequence, so the sequence is not a good key-stream. The distribution of other subsequences of length 4 is also illustrated. >

Moving in the Dark: Enlightening the Spatial Population Ecology of European Cave Salamanders
Population Ecology, EarlyView.We assessed individual interactions, movement ecology and activity patterns of a subterranean population of Speleomantes strinatii, applying spatial capture–recapture modeling to a photographic dataset of 104 individuals. ABSTRACT Space use and movement are fundamental aspects of organisms' ecology, mirroring individual fitness, behavior, and life ...

FEBS Letters, EarlyView.Spinal muscular atrophy (SMA) is a genetic disease affecting motor neurons. Individuals with SMA experience mitochondrial dysfunction and oxidative stress. The aim of the study was to investigate the effect of an antioxidant and neuroprotective substance, ergothioneine (ERGO), on an SMNΔ7 mouse model of SMA.

Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes
FEBS Letters, EarlyView.Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

FEBS Letters, EarlyView.Cells must clear mislocalized or faulty proteins from membranes to survive. The AAA+ ATPase Msp1 performs this task, but dissecting how its six subunits work together is challenging. We engineered linked dimers with varied numbers of functional subunits to reveal how Msp1 subunits cooperate and use energy to extract proteins from the lipid bilayer ...

A New Random Keys Generator Depend on Multi Techniques [PDF]
Engineering and Technology Journal, 2015 A stream cipher is a symmetric cipher which operates with a time-varying transformation onIndividual plaintext digits. By contrast, block ciphers operate with a fixed transformation on large blocks of plaintext digits.
