The significance of geographic location in island studies: a rejoinder [PDF]
Island Studies Journal, 2014 The results pointed out in the note ‘The significance of geographic location in island studies’ by McElroy & Lucas (2014) suggest that the economic performance of small islands is inversely related to their remoteness from the rest of the world and ...

Structural gravity equations with intensive and extensive margins [PDF]
Canadian Journal of Economics/Revue canadienne d'économique, 2010 Abstract Recent trade models with heterogeneous firms have changed the interpretation of gravity equations. Chaney (2008) shows that the effect of distance on the number of exporters and average exports depends on key parameters characterizing the elements of market structure.

Gravity‐Dependent Modulation of Downbeat Nystagmus: Insights From Velocity‐Storage Dysfunction
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Downbeat nystagmus varies with head position, a phenomenon termed gravity‐dependent modulation. We aimed to clarify its mechanism using a velocity‐storage model. Methods In 10 patients with downbeat nystagmus due to cerebellar disorders, we recorded eye movements at different pitch‐ and roll‐axis head positions.

Nambu-Goto equation from three-dimensional gravity
Journal of High Energy PhysicsWe demonstrate that the solutions of three-dimensional gravity obtained by gluing two copies of a spacetime across a junction constituted of a tensile string are in one-to-one correspondence with the solutions of the Nambu-Goto equation in the same ...

Rainbow Gravity Corrections to the Entropic Force
Advances in High Energy Physics, 2018 The entropic force attracts a lot of interest for its multifunctional properties. For instance, Einstein’s field equation, Newton’s law of gravitation, and the Friedmann equation can be derived from the entropic force. In this paper, utilizing a new kind

Compact star in general F(R) gravity: Inevitable degeneracy problem and non-integer power correction
Physics Letters B, 2022 We investigate a compact star in the general F(R) gravity. Developing a novel formulation in the spherically symmetric and static space-time with the matter, we confirm that an arbitrary relation between the mass M and the radius Rs of the compact star ...

Arthritis Care &Research, EarlyView.Objective Studies of damage accrual in patients with systemic lupus erythematosus (SLE) show associations with disease activity measured by the SLE Disease Activity Index 2000 (SLEDAI‐2K), but these associations are imperfect. SLEDAI scores are powerfully influenced by weightings (1–8) assigned to each domain.

Assessing the Impact of SPS Regulations on U.S. Fresh Fruit and Vegetable Exports
Journal of Agricultural and Resource Economics, 2015 Sanitary and phytosanitary (SPS) measures are not new, but their significance in international agrifood trade continues to grow. Much less is known about the trade-restricting potential of these measures because of the difficulty in identifying when SPS ...

Observer‐Based Adaptive Event‐Triggered Tracking Control for Fuzzy TS Systems With Premise Mismatch
International Journal of Adaptive Control and Signal Processing, EarlyView.This paper presents an adaptive logistic event‐triggered observer‐based tracking controller for Takagi‐Sugeno fuzzy systems under constrained inputs and network delays. Leveraging a hybrid LMI and Secretary Bird Optimization approach, this strategy significantly minimizes communication overhead and computational burden while ensuring optimal reference ...
