Resolving passive heat transfer and phase‐change heat in cryogenic CO2 deposition (Desublimation) from CO2/N2 mixtures

open access: yesAIChE Journal, EarlyView.
Abstract In cryogenic CO2 desublimation systems where phase change dominates both heat transfer and separation, conventional lumped thermal‐resistance treatments embed interfacial latent heat into an overall heat‐transfer coefficient, obscuring how phase‐change heat is partitioned between the gas phase and the coolant and limiting diagnostic insight ...

A Unifying Approach to Self‐Organizing Systems Interacting via Conservation Laws

open access: yesAdvanced Intelligent Discovery, EarlyView.
The article develops a unified way to model and analyze self‐organizing systems whose interactions are constrained by conservation laws. It represents physical/biological/engineered networks as graphs and builds projection operators (from incidence/cycle structure) that enforce those constraints and decompose network variables into constrained versus ...

Generalized Extended Matrix Variate Beta and Gamma Functions and Their Applications

open access: yesIngeniería y Ciencia, 2016
In this article, we define and study generalized forms of extended matrix variate gamma and beta functions. By using a number of results from matrix algebra, special functions of matrix arguments and zonal polynomials we derive a number of properties of ...

Programmable Flocks: Hierarchical Swarm Control via Dynamic Parameter Injection

open access: yesAdvanced Intelligent Systems, EarlyView.
We present a method for the control of robot swarms which allows the shaping and the translation of patterns of simple robots (“smart particles”), using two types of devices. These two types represent a hierarchy: a larger group of simple, oblivious robots (which we call the workers) that is governed by simple local attraction forces and a smaller ...

On Cluster C⁎-Algebras

open access: yesJournal of Function Spaces, 2016
We introduce a C⁎-algebra A(x,Q) attached to the cluster x and a quiver Q. If QT is the quiver coming from triangulation T of the Riemann surface S with a finite number of cusps, we prove that the primitive spectrum of A(x,QT) times R is homeomorphic to ...

The Herfindahl neutral point: A firm‐level threshold for managing market concentration with evidence from US hog packing

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract This paper derives a firm‐level threshold, the Herfindahl Neutral Point, from the standard concentration index used in merger review. At this threshold, a marginal expansion leaves the index unchanged. Firms below the threshold reduce concentration when they expand; firms above it increase concentration.

The 4-CB algebra and solvable lattice models

open access: yesJournal of High Energy Physics, 2019
We study the algebras underlying solvable lattice models of the type fusion interaction round the face (IRF). We propose that the algebras are universal, depending only on the number of blocks, which is the degree of polynomial equation obeyed by the ...

Toward a Behavioral Reserve Model in Amyotrophic Lateral Sclerosis

open access: yesAnnals of Neurology, EarlyView.
Objective Behavioral impairment is common in amyotrophic lateral sclerosis (ALS) and strongly affects autonomy, caregiver burden, and outcomes, yet predictors of vulnerability remain unclear. We investigated whether premorbid regulatory traits and socio‐educational exposures are associated with behavioral phenotypes in ALS within a behavioral reserve ...

Research on Heat Transfer Enhancement of Spiral Grooved Tube Heat Exchangers Based on CFD and Artificial Intelligence

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Driven by the energy crisis and carbon neutrality goals, high‐efficiency heat exchange equipment has become a core demand in the industrial sector. The spiral grooved double‐pipe heat exchanger exhibits significant heat transfer enhancement advantages, yet it requires balancing heat transfer efficiency and pressure loss.
