The Triangle Closure is a Polyhedron [PDF]
, 2013 Recently, cutting planes derived from maximal lattice-free convex sets have been studied intensively by the integer programming community. An important question in this research area has been to decide whether the closures associated with certain ...

A version of the penalty method with approximation of the epigraphs of auxiliary functions
Учёные записки Казанского университета: Серия Физико-математические науки, 2019 A method for solving the convex programming problem, which is ideologically close to the known methods of external penalties, was proposed. The method uses auxiliary functions that are built on the general form of the penalty functions.

A Message Passing Algorithm for the Minimum Cost Multicut Problem [PDF]
, 2017 We propose a dual decomposition and linear program relaxation of the NP -hard minimum cost multicut problem. Unlike other polyhedral relaxations of the multicut polytope, it is amenable to efficient optimization by message passing.

Cutting Force Prediction in Drilling of Titanium Alloy
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2012 Cutting force in drilling of Ti-6Al-4V is studied with simulation based on a predictive model. In the force model, three-dimensional chip flow is made by piling up the orthogonal cuttings in the planes containing the cutting velocities and the chip flow ...

On the Effect of Electron Beam Melted Ti6Al4V Part Orientations during Milling
Metals, 2020 The machining of the electron beam melting (EBM) produced parts is a challenging task because, upon machining, different part orientations (EBM layers’ orientations) produce different surface quality even when the same machining parameters are employed ...

Cutting Planes in Combinatorics
European Journal of Combinatorics, 1985 The author uses two combinatorial problems: packing diamonds into a Chinese checkerboard nd Deza's proof of a conjecture of Erdős and Lovàsz [\textit{M. Deza}, J. Comb. Theory, Ser. B, 16, 166-167 (1974; Zbl 0263.05007)] to illustrate how Gomory's cutting plane method for solving integer linear programming problems can be used to solve combinatorial ...

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM
FEBS Letters, EarlyView.Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Bayesian network learning with cutting planes [PDF]
, 2011 The problem of learning the structure of Bayesian networks from complete discrete data with a limit on parent set size is considered. Learning is cast explicitly as an optimisation problem where the goal is to find a BN structure which maximises log ...

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

APPLYING THE THEORY OF THE PLANE IN THE CIVIL ENGINEERING FIELD
Journal of Industrial Design and Engineering Graphics, 2017 To avoid the routine of buildings composed of classical geometric bodies, some methods used in contemporary architecture consist in: the use of intersected solids, the cutting with planes in different positions, as well as the recomposing of volumes.
