Causal faster than light travel from travel-localized second time coordinate

open access: yes, 2019
I present a {\em general relativistic} model with a compactified second time coordinate that {\em a priori} allows for causal, yet faster than light travel in the background of a FLRW geometry, by local modification of a higher dimensional background ...

The Effect of Integrating Travel Time

open access: yes, 2012
This contribution demonstrates the potential gain for the quality of results in a simulation of pedestrians when estimated remaining travel time is considered as a determining factor for the movement of simulated pedestrians. This is done twice: once for

Travel-time-based thermal tracer tomography [PDF]

open access: yesHydrology and Earth System Sciences, 2016
Active thermal tracer testing is a technique to get information about the flow and transport properties of an aquifer. In this paper we propose an innovative methodology using active thermal tracers in a tomographic setup to reconstruct cross-well ...

Spirals in protoplanetary disks from photon travel time [PDF]

open access: yes, 2016
Spiral structures are a common feature in scattered-light images of protoplanetary disks, and of great interest as possible tracers of the presence of planets.

Value of travel time by road type

open access: yesEuropean Transport Research Review, 2022
Travel time is less costly if it is comfortable or can be used productively. One could hence argue that the value of travel time (VTT) of car travellers in economic appraisal should be differentiated by road type, reflecting differences in road quality ...

Bus Travel TIME in the Mixed Traffic Based on Statistica Neural Network [PDF]

open access: yes, 2010
This paper presents the assessment of a number of factors affecting bus travel time and a relationship model between those factors and bus travel time. Statistica Neural Network (SNN) tool is used to solve this complex phenomenon.

Potential Early Risk Biomarkers for Reduced Forced Expiratory Volume in Children Post‐Hematopoietic Cell Transplantation

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT We sought to identify potential early risk biomarkers for lung disease in children post‐allogeneic HCT. Patients with pulmonary function tests 3 months post‐transplant and plasma samples between days 7 and 14 post‐HCT were included. Six of 27 subjects enrolled had reduced forced expiratory volume 1 (FEV1) z scores.

Eucharist, Real Presence, and Time Travel

open access: yesCuestiones Teológicas, 2019
The dogma of transubstantiation defined by the Roman Catholic Church generates several philosophical questions. These problems should be addressed from a perspective broader than the one that has been usually adopted in the recent discussion in Analytic ...

Truth in Time Travel: Subversions of Time in An Adventure [PDF]

open access: yesUniversity of Bucharest Review. Literary and Cultural Studies Series
This article explores how Frances Lamont and Elizabeth Morison’s An Adventure (1913) disrupts temporal and spatial dichotomies through its supposed representations of time travel. An Adventure presents time as a shifting force that aligns with Bergsonian

Causal Loops in Time Travel [PDF]

open access: yes, 2019
About the possibility of time traveling based on several specialized works, including those of Nicholas J. J. Smith ("Time Travel"), William Grey (”Troubles with Time Travel”), Ulrich Meyer (”Explaining causal loops”), Simon Keller and Michael Nelson ...
