Random‐key optimization for 2D irregular packing with reusable area evaluation

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract The diverse constraints of industrial applications lead to variants of two‐dimensional (2D) irregular packing problems that require tailored solution methods. This paper addresses a real‐world industrial challenge by proposing a new problem definition, the maximum reusable contiguous area problem (MRCAP), and a novel metric, the maximum ...

Heterogeneity in Manufacturing Growth Risk

open access: yesJournal of Money, Credit and Banking, EarlyView.
Abstract We analyze differences in output growth risk with respect to financial conditions across U.S. manufacturing industries. Using a multilevel quantile regression approach, we find that industries exhibit heterogeneous increases of downside risk in times of tight financial conditions, while upside potential remains stable.

Generalization of Quasi-Newton Methods: Application to Robust Symmetric Multisecant Updates

open access: yes
Quasi-Newton (qN) techniques approximate the Newton step by estimating the Hessian using the so-called secant equations. Some of these methods compute the Hessian using several secant equations but produce non-symmetric updates.

Artefact‐aware Brillouin microscopy framework for root mechanical phenotyping

open access: yesJournal of Microscopy, EarlyView.
Abstract Plant roots continuously sense and respond to the mechanical signals of their growth environment: root cap function, mucilage secretion, and hormonal regulation jointly adapt root tip mechanics, shaping whether roots penetrate compacted layers or reorient around obstacles. Most current measurements of root mechanical properties require removal

Power Unleashed: Theorizing a Weak Ecology of Checks and Balances and Its Consequences. A Case From the Global South

open access: yesRegulation &Governance, EarlyView.
ABSTRACT This article theorizes about weak checks and balances (C&B) and its plausible consequences. Drawing on empirical data from over 1100 municipal officials in Mexico, the study examines how executive dominance over three key institutions—the local council, internal comptroller offices, and human resources offices—facilitates consequences ...

Comparison of conjunctival pedicle flap to corneal fixation strength achieved by Tisseel® fibrin glue, ethyl cyanoacrylate adhesive, ReSure® hydrogel sealant, and conventional suturing with 8‐0 VICRYL® ophthalmic suture

open access: yesVeterinary Ophthalmology, Volume 28, Issue 2, Page 253-263, March 2025.
Abstract Objective To determine and compare the fixation strength of conjunctival pedicle flaps to cornea achieved via conventional ophthalmic suture and three different adhesive compounds. Animals Studied Ex vivo porcine globes. Procedures Following a 6 mm wide 500‐micron‐restricted depth lamellar keratectomy, conjunctival pedicle flaps were secured ...

The theoretical basis of reservoir pressure in arteries

open access: yesExperimental Physiology, EarlyView.
Abstract The separation of measured arterial pressure into a reservoir pressure and an excess pressure was introduced over 20 years ago as a heuristic hypothesis. Since then it has gained some traction through epidemiological studies that show that various measures of reservoir and excess pressure are independent risk factors for cardiovascular disease.
