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 ...

Centered Polygonal Lacunary Graphs: A Graph Theoretic Approach to p-Sequences of Centered Polygonal Lacunary Functions

open access: yesMathematics, 2019
This work is on the nature and properties of graphs which arise in the study of centered polygonal lacunary functions. Such graphs carry both graph-theoretic properties and properties related to the so-called p-sequences found in the study of centered ...

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

Primes in Intervals and Semicircular Elements Induced by p-Adic Number Fields Q p over Primes p

open access: yesMathematics, 2019
In this paper, we study free probability on (weighted-)semicircular elements in a certain Banach *-probability space ( LS , τ 0 ) induced by measurable functions on p-adic number fields Q p over primes p .

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

Verifying the Firoozbakht, Nicholson, and Farhadian Conjectures up to the 81st Maximal Prime Gap

open access: yesMathematics, 2019
The Firoozbakht, Nicholson, and Farhadian conjectures can be phrased in terms of increasingly powerful conjectured bounds on the prime gaps g n : = p n + 1 - p n .

Restriction theory of the Selberg sieve, with applications [PDF]

open access: yes, 2004
The Selberg sieve provides majorants for certain arithmetic sequences, such as the primes and the twin primes. We prove an L^2-L^p restriction theorem for majorants of this type.
