Triumphs and limits of the Contrastivity-Only Hypothesis [PDF]

open access: yesLinguistic Variation, 2015
The Variable Hierarchy hypothesis of Dresher (2009) has a number of far-reaching consequences and applications – beyond the domain for which it was originally developed – including overspecification, kinship terminology, vowel reduction and whistled languages.

What Drives Negative Investment-Cash Flow Sensitivities? Revenue Effect Versus Corporate Life-Cycle Dynamics

open access: yesSchmalenbach Journal of Business Research, 2023
In order to identify the economic driver of negative investment-cash flow sensitivities (ICFS), we derive testable predictions from extending a theoretical investment model with endogenous financing costs (“revenue effect”) and contrast them with the ...

Towards a computational model for stimulation of the Pedunculopontine nucleus [PDF]

open access: yes, 2009
The pedunculopontine nucleus (PPN) has recently been suggested as a new therapeutic target for deep brain stimulation (DBS) in patients suffering from Parkinson's disease, particularly those with severe gait and postural impairment [1].

Anderson Localization of Matter Waves in 3D Anisotropic Disordered Potentials [PDF]

open access: yes, 2014
Using a cutoff-free formulation of the coherent transport theory, we show that the interference terms at the origin of localization strongly affect the transport anisotropy.

A test of the “;ceiling effect”; hypothesis of positive contrast [PDF]

open access: yesPsychonomic Science, 1970
Seventy-two rats were given 0, 5, 10, or 15 small rewarded trials prior to being shifted to large reward for the remainder of 45 trials. Each of the groups which experienced an upward shift in reward magnitude rapidly approximated the performance of a consistently large rewarded control group, and in no case was a positive contrast effect observed. The

A Comparison of Two Theories of Perceived Distance on the Ground Plane: The Angular Expansion Hypothesis and the Intrinsic Bias Hypothesis

open access: yesi-Perception, 2012
Two theories of distance perception—ie, the angular expansion hypothesis (Durgin and Li, 2011 Attention, Perception, & Psychophysics 73 1856–1870) and the intrinsic bias hypothesis (Ooi et al, 2006 Perception 35 605–624)—are compared.

The common state filter for SLAM [PDF]

open access: yes, 2008
This paper presents the Common State Filter (CSF), a novel and efficient suboptimal Multiple Hypothesis SLAM (MHSLAM) method for Kalman Filter-based SLAM algorithms. Conventional MHSLAM algorithms require the entire vehicle and map state to be copied for

Perceptual distinctiveness between dental and palatal sibilants in different vowel contexts and its implications for phonological contrasts

open access: yesLaboratory Phonology, 2017
Mandarin Chinese has dental, palatal, and retroflex sibilants, but their contrasts before [_i] are avoided: The palatals appear before [i] while the dentals and retroflexes appear before homorganic syllabic approximants (a.k.a. apical vowels).

Feedforward and feedback control in apraxia of speech: effects of noise masking on vowel production [PDF]

open access: yes, 2015
PURPOSE: This study was designed to test two hypotheses about apraxia of speech (AOS) derived from the Directions Into Velocities of Articulators (DIVA) model (Guenther et al., 2006): the feedforward system deficit hypothesis and the feedback system ...

Alzheimer’s disease: the Amyloid hypothesis and the Inverse Warburg effect

open access: yesFrontiers in Physiology, 2015
Epidemiological and biochemical studies show that the sporadic forms of Alzheimer’s disease (AD) are characterized by the following hallmarks : (a) An exponential increase with age ; (b) Selective neuronal vulnerability ; (c) Inverse cancer comorbidity ...
