Cationic antimicrobial peptides are recognized templates for developing a new generation of antimicrobials to combat superbugs. Human cathelicidin LL-37 is an essential host defense molecule in human innate immunity. Previously, we identified KR-12 as the smallest antibacterial peptide of LL-37. KR-12 has a narrow activity spectrum since it is active against Gram-negative Escherichia coli but n...

Our long-term goal is to build a query answering system that can answer questions on a wide variety of topics and explain the answers. In such a situation, a designer faces the challenge of how to specify the KR&R requirements that are needed to answer questions. In this paper, we introduce a categorization of KR&R methods, and apply it to specifying the requirements for answering questions in ...

The problem of determining the maximum size La(n, P ) that a P -free subposet of the Boolean lattice Bn can have, attracted the attention of many researchers, but little is known about the induced version of these problems. In this paper we determine the asymptotic behavior of La∗(n, P ), the maximum size that an induced P -free subposet of the Boolean lattice Bn can have for the case when P is...

Knowledge retention (KR) has been identified as one of the critical factors for maintaining sustainable performance. However, until recently, most of the existing researches have focused on large organizations, while very few studies have mentioned this issue in Small and Medium-Sized Enterprises (SMEs). To redress some of this imbalance in the literature, this paper provides a reference model ...

The Semantic Web (SW) was originally positioned as a combination of Knowledge Representation (KR) and the Web. However, most applications that use SW data today lean more towards the Information Retrieval spectrum. The reason for this is that traditional KR systems are designed to work with datasets that are small, curated, homogeneous, and application-specific. However, the SW is large-scale, ...

Knowledge representation (KR) has traditionally been thought of as the heart of artificial intelligence. Anyone who has ever built an expert system, a natural language system-almost any AI system at all-has had to tackle the problem of representing its knowledge of the world. Despite it ubiquity, for most of AI’s history KR has been a backstage activity. But in the 1980’s it emerged as a field ...

and Applied Analysis 3 the fixed point theory and that a Banach space X has property L if and only if it is reflexive and has the uniform Opial property. For a real vector space X, a function ρ : X → 0,∞ is called amodular if it satisfies the following conditions: i ρ x 0 if and only if x 0; ii ρ αx ρ x for all scalar α with |α| 1; iii ρ αx βy ≤ ρ x ρ y , for all x, y ∈ X and all α, β ≥ 0 with ...

Let r, n be positive integers. Let e be 0 or an integer bigger than 1. Let v1, · · · , vr ∈ Z/eZ and Kr(n) the set of Kleshchev r-partitions of n with respect to (e;Q), where Q := (v1, · · · , vr). The Dipper–James–Murphy conjecture asserts that Kr(n) is the same as the set of (Q, e)-restricted bipartitions of n if r = 2. In this paper we consider an extension of this conjecture to the case whe...

The applicability of the krypton-85 (Kr) clearance method to the study of retinal blood flow in cats, rabbits, and monkeys is discussed. Kr disappearance curves are found to be the same whether the isotope is injected via the common carotid artery or via the lateral long posterior ciliary artery. Kr disappearance curves are found to be similar whether the radioactivity is monitored with a Geige...
