Exploring drivers and costs of partial trans‐Saharan migration in juvenile vultures

open access: yesIbis, EarlyView.
Partial migration occurs when only a subset of individuals within a population undertakes a migratory journey. The decision to migrate can be influenced by intrinsic traits (e.g. sex or physical condition) as well as by extrinsic factors (e.g. social environment or resource availability).

Solution Methods for the Multiple-Choice Knapsack Problem and Their Applications

open access: yesMathematics
The Knapsack Problem belongs to the best-studied classical problems in combinatorial optimization. The Multiple-choice Knapsack Problem (MCKP) represents a generalization of the problem, with various application fields such as industry, transportation ...

Collaborative platooning and routing for mixed fleets of electric automated vehicles and conventional trucks

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract The application of automated ground vehicles (AGVs) is well‐established in closed environments such as port terminals, while their operation in open areas remains challenging. In this work, we set out to overcome this limitation by introducing platooning as a transfer mode in heterogeneous vehicle networks.

Enhancing computational efficiency in solving Knapsack problem: insights from algorithmic parallelization and optimization

open access: yesAdvances in Computing and Engineering
The Knapsack problem is a combinatorial optimization problem whose exact solution using exhaustive search method is impractical. Hence, the application of approximate algorithms is usually considered when encountering this optimization problem.

Prospects of multipurpose biomonitoring for fisheries assessment based on environmental nucleic acids

open access: yesJournal of Fish Biology, EarlyView.
Abstract Methods using environmental nucleic acids have become highly effective for monitoring aquatic biodiversity, with an array of suitable use cases, including metrics for fisheries assessment. Traditional methods for assessing fish populations often rely on invasive techniques with limited spatial and temporal coverage.

On equivalent knapsack problems

open access: yesDiscrete Applied Mathematics, 1986
By aggregating objective function and constraint of a knapsack problem max\(\{\) c'x\(|\) a'x\(\leq b\), \(x\geq 0\) integral\(\}\) an equivalent problem of the following form is obtained: Let \(t=[c_ 1b/a_ 1]+1\) and let \(F(z)=\min \{(c+ta)'x|\) c'x\(\equiv z mod t\), \(x\geq 0\), integral\(\}\).

How to allocate Research (and other) Subsidies [PDF]

open access: yes
A budget-constrained buyer wants to purchase items from a short-listed set. Items are differentiated by observable quality and sellers have private reserve prices for their items. The buyer’s problem is to select a subset of maximal quality.

PKCHD: Towards a Probabilistic Knapsack Public-Key Cryptosystem with High Density

open access: yesInformation, 2019
By introducing an easy knapsack-type problem, a probabilistic knapsack-type public key cryptosystem (PKCHD) is proposed. It uses a Chinese remainder theorem to disguise the easy knapsack sequence. Thence, to recover the trapdoor information, the implicit

“They Look At Us Like Parasites”: The Corporeal Stigmatization and Pathologization of Deportees in Tijuana, Mexico

open access: yesMedical Anthropology Quarterly, EarlyView.
Abstract This article examines the embodied and institutional forms of marginalization experienced by Mexican deportees in Tijuana. Drawing on ethnographic fieldwork conducted in clinics and social service organizations, it explores how deportees are corporeally stigmatized, denied legal recognition, and pathologized as addicts in need of coercive ...
