Investigating the Effect of Gaze Cues and Emotional Expressions on the Affective Evaluations of Unfamiliar Faces. [PDF]
PLoS ONE, 2016 People look at what they are interested in, and their emotional expressions tend to indicate how they feel about the objects at which they look. The combination of gaze direction and emotional expression can therefore convey important information about ...

Lower bound on the compactness of isotropic ultra-compact objects
, 2018 Horizonless spacetimes describing spatially regular ultra-compact objects which, like black-hole spacetimes, possess closed null circular geodesics (light rings) have recently attracted much attention from physicists and mathematicians.

Focusing versus defocusing properties of truly naked black holes [PDF]
, 2008 We study the properties of the congruence of null geodesics propagating near the so-called truly naked horizons (TNH) - objects having finite Kretschmann scalar but with diverging tidal acceleration for freely falling observers. The expansion of outgoing

Neutrino trapping in extremely compact Tolman VII spacetimes
European Physical Journal C: Particles and Fields, 2021 Extremely compact objects trap gravitational waves or neutrinos, assumed to move along null geodesics in the trapping regions. The trapping of neutrinos was extensively studied for spherically symmetric extremely compact objects constructed under the ...

Null safety benchmarks for object initialization [PDF]
Proceedings of the Institute for System Programming of the RAS, 2017 Null pointer dereferencing remains one of the major issues in modern object-oriented languages. An obvious addition of keywords to distinguish between never null and possibly null references appears to be insufficient during object initialization when some fields declared as never null may be temporary null before the initialization completes.

Mass-radius ratio bound for horizonless charged compact object in higher dimensions
Physics Letters B, 2020 In this paper, the mass-radius ratio bound for horizonless compact object in higher dimensions is derived. Instead of considering the various matter conditions of the compact objects following Andreasson's approach, we focus on the conditions for the ...

Null objects and their interpretations [PDF]
, 1994 In this talk, I discussed the semantic and the syntactic nature of null objects (NOs), which are phonetically unrealized but have interpretations, as in (1). (1) a. Mary\u27s baking Ф. [\u27cookies\u27] ..

Calculating Observables in Inhomogeneous Cosmologies I: General Framework
, 2017 We lay out a general framework for calculating the variation of a set of cosmological observables, down the past null cone of an arbitrarily placed observer, in a given arbitrary inhomogeneous metric.

On the Reality of the Accelerating Universe [PDF]
, 2002 Two groups recently deduced the positive value for the cosmological constant, concluding at a high (>= 99%) confidence level that the Universe should be accelerating.

Referential Subject and Object Gaps in Modern Icelandic
Nordlyd: Tromsø University Working Papers on Language & Linguistics, 2004 This paper investigates the nature of subject and object gaps in coordinate structures in Modern Icelandic. Modern Icelandic is considered to be a semi-pro-drop language, since it generally licenses only generic null subjects; object gaps only occur in ...
