Using Functional Programming to recognize Named Structure in an Optimization Problem: Application to Pooling [PDF]

open access: yes, 2016
Branch-and-cut optimization solvers typically apply generic algorithms, e.g., cutting planes or primal heuristics, to expedite performance for many mathematical optimization problems.

Genetic Dissection of Stem Branch Trait and Envisioning of Fixing Heterosis by Vegetative Reproduction in Oryza rufipogon

open access: yesAgronomy, 2022
The stem branch trait of the stolon enables the common wild rice to produce new individuals through vegetative reproduction habit. In order to understand the genetic mechanism of stem branch character, we developed introgression lines (ILs) with the ...

Growth of branches of petung bamboo (Dendrocalamus asper) grafting in soil media, husk charcoal, and their combination

open access: yesJurnal Ilmu Kehutanan, 2014
Recently, the utilization of bamboo is more extensive, but the attention towards its regeneration is not sufficient. The use of stem or branch cuttings are more practical and having more benefits and promising because the cutting materials are more ...

Branch-Cutting Beetles [PDF]

open access: yesNature, 1880
IT is rather curious that the story which Mr. Ober was told in the Carribbees (NATURE, vol. xxii. p. 216) should be generally believed in Southern Brazil also, viz., that a large beetle “seizes a small branch of a tree between its enormously long nippers, and buzzes round and round the branch till this is cut off.” Only in the Antilles this cutting of ...

Understanding plant responses to drought: how important is woody tissue photosynthesis? [PDF]

open access: yes, 2013
Within trees, it is known that a part of the respired CO2 is assimilated in chlorophyll-containing stem and branch tissues. However, the role of this woody tissue photosynthesis in tree functioning remains unclear, in particular under drought stress ...

Understanding Branch Cuts of Expressions [PDF]

open access: yes, 2013
We assume some standard choices for the branch cuts of a group of functions and consider the problem of then calculating the branch cuts of expressions involving those functions. Typical examples include the addition formulae for inverse trigonometric functions.

Branching via Cutting Plane Selection: Improving Hybrid Branching

open access: yes, 2023
Cutting planes and branching are two of the most important algorithms for solving mixed-integer linear programs. For both algorithms, disjunctions play an important role, being used both as branching candidates and as the foundation for some cutting planes.
