Testing Nodal Point Relations by Tracking Sediment Through a Bifurcation on the Jefferson River, MT, USA

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract River bifurcations control water and sediment distribution in fluvial systems, but the physical mechanisms governing sediment partitioning remain poorly validated in natural rivers. We present a comprehensive field test of nodal point relations using radio frequency identification (RFID) tracking of 376 gravel clasts through a meandering river

Sensitivity analysis of the greedy heuristic for binary knapsack problems [PDF]

Greedy heuristics are a popular choice of heuristics when we have to solve a large variety of NP -hard combinatorial problems. In particular for binary knapsack problems, these heuristics generate good results.

A Subquadratic Approximation Scheme for Partition

, 2019
The subject of this paper is the time complexity of approximating Knapsack, Subset Sum, Partition, and some other related problems. The main result is an $\widetilde{O}(n+1/\varepsilon^{5/3})$ time randomized FPTAS for Partition, which is derived from a ...

Evaluation of single versus multiple site of action preemergence herbicides for waterhemp and giant ragweed control in Wisconsin soybean

Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract The use of preemergence (PRE) herbicides with soil residual activity is recognized as an effective strategy for early‐season weed management in Midwest US soybean [Glycine max (L.) Merr.] production. The efficacy of soybean PRE herbicides with single and multiple sites of action (SOAs), including acetolactate synthase (ALS), photosystem II ...

List-Based Simulated Annealing Algorithm With Hybrid Greedy Repair and Optimization Operator for 0–1 Knapsack Problem

IEEE Access, 2018
List-based simulated annealing (LBSA) algorithm, which uses list-based cooling scheme to control the change of parameter temperature, was first proposed for traveling salesman problem. This paper extends the application of LBSA algorithm for 0-1 knapsack

Prevalence of Low Back Pain and Associated Factors Among University Students in Bangladesh: A Cross‐Sectional Study

Health Science Reports, Volume 9, Issue 3, March 2026.
ABSTRACT Background University students are susceptible to low back pain (LBP) because of their predisposition to various factors that have been previously linked to the increased risk of LBP among other populations. There is a substantial lack of research that explores the prevalence and risk factors of LBP among university students in Bangladesh ...

Perfect Matching Under Precedence Constraints

Networks, Volume 87, Issue 2, Page 175-190, March 2026.
ABSTRACT In this article, we motivate and define variants of perfect matching under precedence constraints where a perfect matching is built incrementally and precedence constraints ensure that an edge may only be added to the matching if the edge's predecessor vertices have already been covered.

A Heuristics-Guided Simplified Discrete Harmony Search Algorithm for Solving 0-1 Knapsack Problem

Algorithms
The harmony search (HS) algorithm is a novel metaheuristic which has been widely used to solve both continuous and discrete optimization problems. In order to improve the performance and simplify the implementation of the HS algorithm for solving the 0-1
