Symmetry breaking in periodic and solitary gravity-capillary waves on water of finite depth [PDF]

open access: yes, 1987
A weakly nonlinear model is developed from the Hamiltonian formulation of water waves, to study the bifurcation structure of gravity-capillary waves on water of finite depth.

Investigating Dynamic Characteristics of Cavitation in Insulating Oil Microgaps Under Vibration: Theoretical Analysis and Experimental Observation

open access: yesHigh Voltage, EarlyView.
ABSTRACT The internal pressure fluctuations caused by vibration in oil‐immersed electrical equipment can initiate bubbles within narrow oil gaps, reducing the electrical strength of equipment and giving rise to the problem of abnormal gas production in oil‐immersed equipment.

Nest Survival Models and Genomics Illuminate Hybridisation Attempts, Guiding Culturally Informed Management to Recover a Critically Endangered Seabird

open access: yesAnimal Conservation, EarlyView.
Long‐term monitoring has revealed hybridisation attempts between the Critically Endangered Kuaka Whenua Hou (KWH, Pelecanoides whenuahouensis) and the abundant Kuaka (P. urinatrix). Here we use modelling based on population monitoring data in tandem with genomic data to investigate these attempts and the risk they pose to KWH recovery.

How do ecologists estimate occupancy in practice?

open access: yesEcography, EarlyView.
Over 20 years ago, ecologists were introduced to the site occupancy model (SOM) for estimating occupancy rates from detection‐nondetection data. In the ensuing decades, the SOM and its hierarchical modeling extensions have become mainstays of quantitative ecology, and estimating occupancy rates has become one of the most common applications of ...

Solving Daniel Bernoulli's St Petersburg Paradox: The Paradox which is not and never was [PDF]

open access: yes
It has been accepted for over 270 years that the expected monetary value (EMV)of the St Petersburg game is infinite. Accepting this leads to a paradox; no reasonable person is prepared to pay the predicted large sum to play the game but will only pay ...

The U‐shaped effect of logic multiplicity on organizational performance: Evidence from the US healthcare industry

open access: yesEuropean Management Review, EarlyView.
Abstract We investigate the effect of logic multiplicity on organizational performance and hypothesize that logics may impact performance in view of their sheer number. We further propose that the market logic embedded in the for‐profit legal form can positively moderate the impact of multiple logics on performance.

Transforming Probabilities without Violating Stochastic Dominance [PDF]

open access: yes, 1989
The idea of expected utility, to transform payments into their utilities before calculating expectation, traces back at least to Bernoulli (1738). It is a very natural idea to transform, analogously, probabilities.

Objective diagnosis of alar fold collapse in active Standardbred trotting racehorses using nasopharyngeal airway pressure measurements

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Clinical evaluation of alar fold (AF) collapse is presently based upon subjective evaluation of improvement in breathing and respiratory noise after suturing the AFs dorsally. Objectives To evaluate use of nasopharyngeal airway pressure (NAP) as an objective method of assessing for the presence of AF collapse during exercise.

Limit Orders and Knightian Uncertainty

open access: yesInternational Economic Review, EarlyView.
ABSTRACT A wide variety of financial instruments allows risk‐averse traders to reduce their exposure to risk. This raises the question of what financial instruments allow ambiguity‐averse traders to reduce their exposure to ambiguity. We show in this paper that price‐contingent orders, such as limit orders, are sufficient: In a two‐period trading model,
