A broader perspective on point of view: logophoricity in Ogonoid languages [PDF]

open access: yes, 2006
Logophoric marking in the Ogonoid family (Benue-Congo, Niger-Congo) differs significantly from most other logophoric reference systems in that these languages employ distinct verbal suffixes in logophoric domains, in addition to regular participant ...

Relativistic Positioning Systems

open access: yes, 2006
The theory of relativistic {\em location systems} is sketched. An interesting class of these systems is that of relativistic {\em positioning systems,} which consists in sets of four clocks broadcasting their proper time.

A Reference Architecture for the American Multi-Modal Energy System [PDF]

open access: yesarXiv, 2020
The American Multimodal Energy System (AMES) is a system-of-systems comprised of four separate but interdependent infrastructure systems: the electric grid, the natural gas system, the oil system, and the coal system. Their interdependence creates the need to better understand the underlying architecture in order to pursue a more sustainable, resilient

Corrected mu_delta for Stars of Hipparcos Catalogue from Independent Latitude Observations over Many Decades [PDF]

open access: yesSerbian Astronomical Journal, 2011
During the last century, there were many so-calledindependent latitude (IL) stations with the observations whichwere included into data of a few international organizations(like Bureau International de l'Heure -- BIH, International PolarMotion Service --

A quantum theory for a total system including a reference system [PDF]

open access: yesarXiv, 2008
The standard formalism of quantum mechanics is extended to describe a total system including the reference system (RS), with respect to which the total system is described. The RS is assumed to be able to act as a measuring apparatus, with measurement records given by the values of some reference properties of the RS.

Reproductive Management of Dairy Cows with Particular Reference to Organic Systems [PDF]

open access: yes, 2008
Reproductive efficiency is a major factor affecting production and economic efficiency indairy herds. In seasonally calving herds the requirement of good reproductive performance is of greater importance than in other production systems in order to ...

A Survey of Autoantibodies to Self Antigens in Graves' Disease Patients with Thyroid-Associated Ophthalmopathy

open access: yesEuropean Journal of Inflammation, 2013
Thyroid Associated Ophthalmopathy (TAO) is a complex pathology to treat and a considerable threat for Graves' Disease (GD) patients. Thus, there is great interest to find tools able to predict the onset and prognosis of TAO.

Reduced Reference Frame Transform: Deconstructing Three-Phase Four-Wire Systems

open access: yesIEEE Access, 2020
This paper proposes a new reference frame, namely Reduced Reference Frame (RRF), specially suited for unbalanced three–phase four–wire systems which improves the performance of the classical Fortescue, Clarke and Park transformations.

Remarks on multivariate Gaussian Gabor frames [PDF]

open access: yes, 2010
We report on initial findings on Gabor systems with multivariate Gaussian window. Unlike the existing characterisation for dimension one in terms of lattice density, our results indicate that the behavior of Gaussians in higher-dimensional Gabor systems ...
