The direction of time: from the global arrow to the local arrow [PDF]
Int.J.Theor.Phys.42:2487-2504,2003, 2003 In this paper we discuss the traditional approaches to the problem of the arrow of time. On the basis of this discussion we adopt a global and non-entropic approach, according to which the arrow of time has a global origin and is an intrinsic, geometrical feature of space-time.

, 2011 We introduce an additional structure on ribbon graphs, arrow structure. We extend the Bollob\'as-Riordan polynomial to ribbon graph with this structure. The extended polynomial satisfies the contraction-deletion relations and naturally behaves with respect to the partial duality of ribbon graphs.

Solid-Phase Microextraction Arrow for the Sampling of Volatile Organic Compounds in Milk Samples
Separations, 2020 A novel sample preparation method based on the use of the Arrow solid-phase microextraction device was used to extract and preconcentrate volatile organic compounds (VOCs) from milk samples prior to their determination by gas chromatography–mass ...

Arrow Contraction and Expansion in Tropical Diagrams [PDF]
arXiv, 2019 Arrow contraction applied to a tropical diagram of probability spaces is a modification of the diagram, replacing one of the morphisms by an isomorphims, while preserving other parts of the diagram. It is related to the rate regions introduced by Ahlswede and K\"orner.

International Journal of Food Properties, 2019 The ability to readily determine the composition of brown rice vinegar is important for quality assurance purposes. To that end, solid–phase microextraction (SPME)–Arrow method was optimized for the determination of volatile organic compounds (VOCs) from

Is Time's Arrow Perspectival? [PDF]
, 2015 We observe entropy decrease towards the past. Does this imply that in the past the world was in a non-generic microstate? I point out an alternative. The subsystem to which we belong interacts with the universe via a relatively small number of quantities,

Arbitrary Arrow Update Logic with Common Knowledge is neither RE nor co-RE [PDF]
Electronic Proceedings in Theoretical Computer Science, 2017 Arbitrary Arrow Update Logic with Common Knowledge (AAULC) is a dynamic epistemic logic with (i) an arrow update operator, which represents a particular type of information change and (ii) an arbitrary arrow update operator, which quantifies over arrow ...

ARROW: restoration-aware traffic engineering
Conference on Applications, Technologies, Architectures, and Protocols for Computer Communication, 2021 Fiber cut events reduce the capacity of wide-area networks (WANs) by several Tbps. In this paper, we revive the lost capacity by reconfiguring the wavelengths from cut fibers into healthy fibers.
