Relating the thermodynamic arrow of time to the causal arrow [PDF]
Journal of Statistical Mechanics: Theory and Experiment, 2007 Consider a Hamiltonian system that consists of a slow subsystem S and a fast subsystem F. The autonomous dynamics of S is driven by an effective Hamiltonian, but its thermodynamics is unexpected.

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.

Arrow R-CNN for handwritten diagram recognition
International Journal on Document Analysis and Recognition, 2021 We address the problem of offline handwritten diagram recognition. Recently, it has been shown that diagram symbols can be directly recognized with deep learning object detectors. However, object detectors are not able to recognize the diagram structure.

Clinical Practice and Cases in Emergency Medicine, 2019 A 33-year-old male was brought to the emergency department after a penetrating arrow injury to the chest. Initial evaluation revealed the arrow was penetrating the sternum, lung, and aortic arch. Because the patient was in a remote area, timely transfer to a specialized center for definitive operative repair was delayed approximately 24 hours ...

Machine learning the thermodynamic arrow of time [PDF]
Nature Physics, 2019 The asymmetry in the flow of events that is expressed by the phrase ‘time’s arrow’ traces back to the second law of thermodynamics. In the microscopic regime, fluctuations prevent us from discerning the direction of time’s arrow with certainty.

EURASIP Journal on Information Security, 2008 This paper makes an account of the design and investigations done for the still image watermarking technique used in the 2nd edition of the BOWS challenge. This technique is named "broken arrows" for some reasons given later on, and abbreviated "BA." This zero-bit algorithm is an implementation of a recent theoretical result by Merhav and Sabbag (2008)

The Astrophysical Journal, 1976 A model of the universe which resolves the apparent contradiction between the historical and the thermodynamic arrows of time is presented. Both arrows are reconciled with the almost time-symmetric character of physical laws at the microscopic level. The theory implies that the universe is unfolding in time but not unraveling. (BJG)
