Primality deterministic and primality probabilistic tests

open access: yesStatistica, 2007
In this paper the A. comments the importance of prime numbers in mathematics and in cryptography. He remembers the very important researches of Eulero, Fermat, Legen-re, Rieman and others scholarships. There are many expressions that give prime numbers. Between them Mersenne’s primes have interesting properties.

BIQUADRATIC RECIPROCITY AND A LUCASIAN PRIMALITY TEST

open access: yes, 2008
. Let {sk,k ≥ 0} be the sequence defined from a given initial value, the seed, s0, by the recurrence sk+1 = s2 k − 2,k ≥ 0. Then, for a suitable seed s0, thenumberMh,n = h · 2n − 1(whereh<2n is odd) is prime iff sn−2 ≡ 0modMh,n.

Geometric primality tests using genus 1 & 2 curves [PDF]

open access: yes, 2017
We revisit and generalize some geometric techniques behind deterministic primality testing for some integer sequences using curves of genus 1 over finite rings. Subsequently we develop a similar primality test using the Jacobian of a genus 2 curve.

Integrated location–inventory planning for slow‐moving demands with waiting time limitations

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract This paper studies a stochastic facility location problem integrated with inventory and transportation decisions (SFLPIT) for supply chains with slow‐moving stock‐keeping units (SKUs). Local stores often avoid maintaining such SKUs, resulting in customer demand being fulfilled directly by a central distribution center (DC), where the ...

Assessing second‐price auctions for parcel exchanges in last‐mile logistics

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract The rapid growth of e‐commerce has led to multiple carriers operating in the same regions, creating opportunities for collaboration. However, logistics companies typically operate independently, leading to inefficiencies. Horizontal cooperation, where carriers share resources and infrastructure, can improve efficiency and reduce costs.

Implementations of the Improved AKS Primality Testing Algorithm

open access: yes工程科学与技术, 2009
:The AKS algorithm successfully solved the noted problem of deterministic primality testing in polynomial time, but it was not yet suitable for the real application, thus it was improved in series.

Implementation of Goldwasser-Kilian primality test on elliptic curves [PDF]

open access: yes
Due to the development in information security and cryptography fields, in particular public-key cryptography, the importance of searching for large prime numbers has increased. Solovay and Strassen, in 1977, and Miller and Rabin, in 1980, were developed

Conceptual Anchors in Longitudinal Qualitative Health Research: Using a Methodological Adjunct in Longitudinal Interpretative Phenomenological Analysis

open access: yesJournal of Advanced Nursing, EarlyView.
ABSTRACT Aims To highlight how Longitudinal Experiential Concepts can be used as conceptual anchors within Longitudinal Interpretative Phenomenological Analysis to gain temporal interpretative phenomenological insights, a lack of which can be a criticism levelled at novice nurse or midwife researchers utilising phenomenological research methods ...

World Beliefs Moderate the Effects of Trauma and Severe Illness on Emotional Distress

open access: yesJournal of Personality, EarlyView.
ABSTRACT Objective Severe illness and trauma can cause significant psychological distress, but individuals differ in their responses. This research tested whether world beliefs—fundamental assumptions about the nature of the world—moderate the relationship between negative life experiences and emotional distress.
