On a density problem of Erdös

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1999
For a positive integer n, let P(n) denotes the largest prime divisor of n and define the set: 𝒮(x)=𝒮={n≤x:n   does not divide   P(n)!}. Paul Erdös has proposed that |S|=o(x) as x→∞, where |S| is the number of n∈S. This was proved by Ilias Kastanas.

Shifting evaluation windows: predictable forward primes with long SOAs eliminate the impact of backward primes. [PDF]

open access: yesPLoS ONE, 2013
Recent work suggests that people evaluate target stimuli within short and flexible time periods called evaluation windows. Stimuli that briefly precede a target (forward primes) or briefly succeed a target (backward primes) are often included in the ...

Combinatorics of H-primes in quantum matrices [PDF]

open access: yes, 2006
For q epsilon C transcendental over Q, we give an algorithmic construction of an order-isomorphism between the set of H-primes of O-q (M-n (C)) and the sub-poset S of the (reverse) Bruhat order of the symmetric group S-2n consisting of those permutations

Understanding the role of the 'self' in the social priming of mimicry. [PDF]

open access: yesPLoS ONE, 2013
People have a tendency to unconsciously mimic other's actions. This mimicry has been regarded as a prosocial response which increases social affiliation.

Semantic priming, prime reportability, and retroactive priming are interdependent [PDF]

open access: yesMemory & Cognition, 1988
In two experiments, semantic analysis of prime words was measured in terms of facilitation in naming a semantically related target word. Targets were degraded but gradually clarified until the subject named them. Subjects reported the prime after naming the target. Experiment 1 used semantic associates as primes at a 50-msec prime-target stimulus onset

Morphological Priming Effects in L2 English Verbs for Japanese-English Bilinguals

open access: yesFrontiers in Psychology, 2022
For native (L1) English readers, masked presentations of past-tense verb primes (e.g., fell and looked) produce faster lexical decision latencies to their present-tense targets (e.g., FALL and LOOK) than orthographically related (e.g., fill and loose) or

ON RUSSO'S CONJECTURE ABOUT PRIMES [PDF]

open access: yes, 2001
Let n, k be positive integres with k>2, and let b be a posItIve number with b> I. In this paper we prove that if n>C(k), where C(k) IS an effectively computable constant depending on k, then we have C (n,k)

Matrices induced by arithmetic functions acting on certain Krein spaces

open access: yesSpecial Matrices, 2017
In this paper, we study matrices induced by arithmetic functions under certain Krein-space representations induced by (multi-)primes less than or equal to fixed positive real numbers.

Second-order linear recurrences with identically distributed residues modulo pᵉ [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
Let p be an odd prime and let u(a,-1) and u(a',-1) be two Lucas sequences whose discriminants have the same nonzero quadratic character modulo p and whose periods modulo p are equal.
