ɛ-Poly-l-lysine (ɛ-PL) is a cationic peptide with a broad-spectrum antimicrobial activity. This study investigates the use of ɛ-PL as natural antimicrobial to inhibit fungal growth and to reduce aflatoxins (AFs) production. Antifungal activity of starch biofilms with different concentrations of ɛ-Poly-l-lysine (ɛ-PL) was determined in solid medium against Aspergillus parasiticus (AFs producer) ...

A model for the Reynolds-number dependence of the dimensionless dissipation rate C(ɛ) was derived from the dimensionless Kármán-Howarth equation, resulting in C(ɛ)=C(ɛ,∞)+C/R(L)+O(1/R(L)(2)), where R(L) is the integral scale Reynolds number. The coefficients C and C(ɛ,∞) arise from asymptotic expansions of the dimensionless second- and third-order structure functions. This theoretical work was ...

The present work analyzes theoretically and verifies the advantage of utilizing ɛ-microcantilever assemblies in microsensing applications. The deflection profile of these innovative ɛ-assembly microcantilevers is compared with that of the rectangular microcantilever and modified triangular microcantlever. Various force-loading conditions are considered. The theorem of linear elasticity for thin...

Bulk modulus of elasticity (ɛ), depicting the flexibility of plant tissues, is recognized as an important component in maintaining internal water balance. Elevated ɛ and comparatively low osmotic potential (Ψπ) may work in concert to effectively maintain vital cellular water content. This concept, termed the 'cell water conservation hypothesis', may foster tolerance for lower soil-water potenti...

This study used an active multiple-deviant oddball design to investigate the time-course of normalization processes that help listeners deal with between-speaker variability. Electroencephalograms were recorded while Dutch listeners heard sequences of non-words (standards and occasional deviants). Deviants were [ipapu] or [ɛpapu], and the standard was [(I)(ɛ)papu], where [(I)(ɛ)] was a vowel th...

BACKGROUND Myoclonus-dystonia is a neurogenic movement disorder caused by mutations in the gene encoding ɛ-sarcoglycan. By contrast, mutations in the α-, β-, γ-, and δ-sarcoglycan genes cause limb girdle muscular dystrophies. The sarcoglycans are part of the dystrophin-associated protein complex in muscle that is disrupted in several types of muscular dystrophy. Intriguingly, patients with myoc...

Different protein kinase C (PKC) isoforms have distinct roles in regulating cell functions. The conventional (α, β, γ) and novel (δ, ɛ, η, θ) classes are targets of phorbol ester tumor promoters, which are surrogates of endogenous second messenger, diacylglycerol. The promoter-stimulated disappearance of filopodia was investigated by use of blocking peptides (BPs) that inhibit PKC maturation an...

Three DNA polymerases - Pol α, Pol δ and Pol ɛ - are essential for DNA replication. After initiation of DNA synthesis by Pol α, Pol δ or Pol ɛ take over on the lagging and leading strand respectively. Pol δ and Pol ɛ perform the bulk of replication with very high fidelity, which is ensured by Watson-Crick base pairing and 3'exonuclease (proofreading) activity. Yeast models have shown that mutat...

Recurrence networks are a powerful nonlinear tool for time series analysis of complex dynamical systems. While there are already many successful applications ranging from medicine to paleoclimatology, a solid theoretical foundation of the method has still been missing so far. Here, we interpret an ɛ-recurrence network as a discrete subnetwork of a "continuous" graph with uncountably many vertic...

The study aimed to compare the perception and production of English front vowel pairs: /i/-/ɪ / and /ɛ /-/æ/ and to identify their perception-production link by Taiwanese EFL learners through minimal-pair tests. Twenty Grade 6 elementary school students in Taiwan were randomly selected to be engaged in two tests with 4 front vowels (/i/, /ɪ /, /ɛ /, /æ/) embedded in ten monosyllabic words respe...
