The mathematical constraint of the counterexample of Goldbach's strong conjecture

open access: yes, 2020
In this paper, we have demonstrated a proof that the Counterexample of Goldbach's strong conjecture is impossible in two steps: First, we reformulated Goldbach's strong conjecture using the subtraction connotation.

Improving Affordability and Accessibility for Socially‐Beneficial Services via Government Incentives

open access: yesNaval Research Logistics (NRL), EarlyView.
ABSTRACT Many socially‐beneficial services, like dental care, suffer from a dual challenge: Low affordability for citizens and long waiting times due to insufficient provider capacity. We model a government's problem of designing subsidy policies to address this issue.

A Branch‐and‐Price Algorithm for the Symmetric Electric Traveling Salesman Problem

open access: yesNetworks, EarlyView.
ABSTRACT The Electric Traveling Salesman Problem (ETSP) is a variant of the well‐known TSP in which an electric vehicle must visit a set of customers minimizing the total cost of its route. The vehicle is assumed to be equipped with a battery of limited capacity that may need to be recharged along the route.

Reasoning Together or Clicking Through? Analyzing Patterns of Group Science Talk On and Off Individualized Computers

open access: yesScience Education, EarlyView.
ABSTRACT In this article, I examine group science talk within the classrooms of three urban secondary science teachers who regularly use one‐to‐one computers to mediate their NGSS‐aligned science instruction. I combine methods of framing analysis (Goffman 1974; Tannen 1993) and interaction analysis (Jordan and Henderson 1995) to illustrate differences ...
