The Multiverse and Particle Physics

John F. Donoghue
2016 Annual Review of Nuclear and Particle Science  
In this review, we survey the motivations for the multiverse and impact of the idea of the multiverse on the search for new physics beyond the Standard Model.  ...  The possibility of fundamental theories with very many ground states, each with different physical parameters, changes the way that we approach the major questions of particle physics.  ...  of space-time (46) .  ...

Making predictions in the multiverse

Ben Freivogel
2011 Classical and quantum gravity  
I describe reasons to think we are living in an eternally inflating multiverse where the observable "constants" of nature vary from place to place.  ...  The major obstacle to making predictions in this context is that we must regulate the infinities of eternal inflation. I review a number of proposed regulators, or measures.  ...  The major obstacle of principle to implementing the program of making predictions by counting observations in the multiverse is the existence of divergences.  ...

Relaxed-currency serializability for middle-tier caching and replication

Philip A. Bernstein, Alan Fekete, Hongfei Guo, Raghu Ramakrishnan, Pradeep Tamma
2006 Proceedings of the 2006 ACM SIGMOD international conference on Management of data - SIGMOD '06  
We study concurrency control for a transactional model that allows update transactions to read out-of-date copies.  ...  We offer a definition of correctness for this model and present algorithms to ensure several of the most interesting freshness constraints.  ...  They measure database-level inconsistency (fuzziness), while we measure divergence in terms of user-specified currency limits on individual objects or groups of objects read by a transaction.  ...

Flexeme: untangling commits using lexical flows

Profir-Petru Pârțachi, Santanu Kumar Dash, Miltiadis Allamanis, Earl T. Barr
2020 Proceedings of the 28th ACM Joint Meeting on European Software Engineering Conference and Symposium on the Foundations of Software Engineering  
At the untangling task on a C# corpus, our implementation, Heddle, improves the state-of-the-art on accuracy by 0.14, achieving 0.81, in a fraction of the time: Heddle is 32 times faster than the previous  ...  We present a novel data structure, the -NFG, a multiversion Program Dependency Graph augmented with name flows.  ...  This lets us control the level of fuzziness while matching nodes. In this work, we have chosen to be string edit distance and set = 1.0 thus requiring exact matches.  ...

Generalized Type-2 Fuzzy Parameter Adaptation in the Marine Predator Algorithm for Fuzzy Controller Parameterization in Mobile Robots

Felizardo Cuevas, Oscar Castillo, Prometeo Cortés-Antonio
2022 Symmetry  
In the state of the art, it has been shown that type-2 fuzzy increases metaheuristic performance when adapting parameters, although there is also an increase in the execution time.  ...  A second case for FMPA is also presented, which is the optimal fuzzy control design, in the search for the optimal membership function parameters.  ...  fuzzy controller of an autonomous mobile robot is presented in [23] .  ...

A Confidence-Based Software Voter for Safety-Critical Systems

Mohammadreza Rezaee, Yasser Sedaghat, Masoud Khosravi-Farmad
2014 2014 IEEE 12th International Conference on Dependable, Autonomic and Secure Computing  
The proposed technique considers weight oscillation and confidence of each module to improve availability and safety of the voter.  ...  Since the voter is a single point of failure in the techniques, availability and safety are essential requirements. In this paper a confidence-based software voting technique is proposed.  ...  Time overhead of running fuzzy rules may lead the system toward a situation that passes the real-time deadlines, so simpler algorithms are preferred.  ...

Fuzzy Instantons in Landscape and Swampland: Review of the Hartle–Hawking Wave Function and Several Applications

Dong-han Yeom
2021 Universe  
Fuzzy instantons can have multiple physical applications. In slow-roll inflation models, fuzzy instantons can explain the probability distribution of the initial conditions of the universe.  ...  Although the potential shape does not satisfy the slow-roll conditions due to the swampland criteria, the fuzzy instantons can still explain the origin of the universe.  ...  Conflicts of Interest: The author declares no conflict of interest.  ...

Fuzzy instantons in landscape and swampland: review of the Hartle-Hawking wave function and several applications [article]

Dong-han Yeom
2021 arXiv   pre-print
These fuzzy instantons can have various physical applications. In slow-roll inflation models, fuzzy instantons can explain the probability distribution of the initial conditions of the universe.  ...  Even though the potential shape does not satisfy the slow-roll conditions following the swampland criteria, still the fuzzy instantons can explain the origin of the universe.  ...  Eventually, in somewhere of the multiverse, any fine-tuned parameters can be realized.  ...

Islands in Multiverse Models [article]

Sergio E. Aguilar-Gutierrez, Aidan Chatwin-Davies, Thomas Hertog, Natalia Pinzani-Fokeeva, Brandon Robinson
2021 arXiv   pre-print
When these are sufficiently large we find that an island develops covering most of the rest of the multiverse, leading to a Page-like transition.  ...  We consider multiverse models in two-dimensional linear dilaton-gravity theories as toy models of false vacuum eternal inflation.  ...  Acknowledgments We thank Ning Bao, Arjun Kar, Jason Pollack, Jacopo Sisti, James Sully, and Mark Van Raamsdonk for helpful discussions during the preparation of this manuscript, as well as Kristan Jensen  ...
