Inference for Differential Equation Models using Relaxation via Dynamical Systems

open access: yes, 2017
Statistical regression models whose mean functions are represented by ordinary differential equations (ODEs) can be used to describe phenomenons dynamical in nature, which are abundant in areas such as biology, climatology and genetics. The estimation of

New Michigan Tick (Acari: Ixodidae) and Flea (Siphonaptera: Ceratophyllidae) Records From Colonial Nesting Birds [PDF]

open access: yes, 2018
Banding and censusing large numbers of gull chicks over a 30-year period on Great Lakes islands has produced a collection of five individual ticks from two Herring Gull (Larus argentatus) chicks.

Psychopathy traits and their link to emotion recognition impairments in conduct disorder

open access: yesJCPP Advances, EarlyView.
Abstract Background Neurocognitive models suggest that callous‐unemotional (CU) traits in youths with conduct disorder (CD) are linked to emotion recognition impairments, particularly in identifying distress emotions like fear and sadness. However, CD may be accompanied by grandiose‐manipulative (GM) and/or impulsive‐irresponsible (II) traits in ...

Parasitic infections of wild rabbits and hares [PDF]

open access: yesVeterinarski Glasnik, 2014
The paper presents the most important parasitic infections of wild rabbits and hares, which harmful effect in this animal population is manifested as a gradual weakening of the immune system, reduction in fertility, weight loss and constant ...

Moving forward in circles: challenges and opportunities in modelling population cycles [PDF]

open access: yes, 2017
Population cycling is a widespread phenomenon, observed across a multitude of taxa in both laboratory and natural conditions. Historically, the theory associated with population cycles was tightly linked to pairwise consumer–resource interactions and ...

Decadal Changes of UV Aerosol Optical Depth in Hobart, Australia Measured With a Brewer MKIII: Relationship to Bushfire Events and Climate Indices

open access: yesInternational Journal of Climatology, EarlyView.
Monthly average aerosol optical depth at 320 nm obtained with a Brewer MKIII spectrophotometer for Hobart, Australia (42.8806° S, 147.3250° E) over a 21‐year period. There is a linear trend of 15.4% per decade. There are 9 months when the average aerosol optical depth exceeds twice the monthly standard deviation.

Variational finite-difference representation of the kinetic energy operator

open access: yes, 2001
A potential disadvantage of real-space-grid electronic structure methods is the lack of a variational principle and the concomitant increase of total energy with grid refinement.

The Illusion of Structural Order: Evaluating the Suppression of Amorphous Carbon Black Pigment Bands in SSE‐Processed Handheld Raman Spectra

open access: yesJournal of Raman Spectroscopy, EarlyView.
The handheld Raman with SSE system efficiently mitigates fluorescence; however, it may also bias the Raman response towards graphitic domains in carbon‐based black pigments, thereby concealing amorphous carbon contributions that are critical for pigment type identification.

Corporate Psychopaths as Risk Factors: The Role of Managerial Control and Competition for Risk Governance

open access: yesStrategic Change, EarlyView.
ABSTRACT The increasing prevalence of corporate scandals and dysfunction linked to psychopathic leaders has prompted significant research into the drivers and effects of psychopathy in business. This paper examines corporate psychopathy, focusing on individuals with extreme selfishness, callousness, and manipulative behavior who often achieve ...
