Curvature and higher order Buser inequalities for the graph connection Laplacian (2019)
Journal Article
Liu, S., Muench, F., & Peyerimhoff, N. (2019). Curvature and higher order Buser inequalities for the graph connection Laplacian. SIAM Journal on Discrete Mathematics, 33(1), 257-305. https://doi.org/10.1137/16m1056353

We study the eigenvalues of the connection Laplacian on a graph with an orthogonal group or unitary group signature. We establish higher order Buser type inequalities, i.e., we provide upper bounds for eigenvalues in terms of Cheeger constants in the...

Testing random effects in linear mixed-effects models with serially correlated errors (2019)
Journal Article
Drikvandi, R., & Noorian, S. (2019). Testing random effects in linear mixed-effects models with serially correlated errors. Biometrical Journal, 61(4), 802-812. https://doi.org/10.1002/bimj.201700203

In linear mixed‐effects models, random effects are used to capture the heterogeneity and variability between individuals due to unmeasured covariates or unknown biological differences. Testing for the need of random effects is a nonstandard problem b... Read More about Testing random effects in linear mixed-effects models with serially correlated errors.

A heuristic survival signature based approach for reliability-redundancy allocation (2019)
Journal Article
Huang, X., Coolen, F., & Coolen-Maturi, T. (2019). A heuristic survival signature based approach for reliability-redundancy allocation. Reliability Engineering & System Safety, 185, 511-517. https://doi.org/10.1016/j.ress.2019.02.010

In recent research, the major focus on reliability-redundancy allocation problems has been on the possibility of using more efficient and effective algorithms to improve convergence speed and solution accuracy of the optimization model. But the model... Read More about A heuristic survival signature based approach for reliability-redundancy allocation.

Gaining more understanding about reservoir behavior through assimilation of breakthrough time and productivity deviation in the history matching process (2019)
Journal Article
Formentin, H. N., Almeida, F. L. R., Avansi, G. D., Maschio, C., Schiozer, D. J., Caiado, C., …Goldstein, M. (2019). Gaining more understanding about reservoir behavior through assimilation of breakthrough time and productivity deviation in the history matching process. Journal of Petroleum Science and Engineering, 173, 1080-1096. https://doi.org/10.1016/j.petrol.2018.10.045

History matching (HM) is an inverse problem where uncertainties in attributes are reduced by comparison with observed dynamic data. Typically, normalized misfit summarizes dissimilarities between observed and simulation data. Especially for long-time...

Mean Curvature Flow of Compact Spacelike Submanifolds in Higher Codimension (2019)
Journal Article
Guilfoyle, B., & Klingenberg, K. (2019). Mean Curvature Flow of Compact Spacelike Submanifolds in Higher Codimension. Transactions of the American Mathematical Society, 372(9), 6263-6281. https://doi.org/10.1090/tran/7766

We prove the longtime existence for mean curvature flow of a smooth n-dimensional spacelike submanifold of an (n + m)-dimensional manifold whose metric satisfies the timelike curvature condition.

Searching for the odderon in ultraperipheral proton-ion collisions at the LHC (2019)
Journal Article
Harland-Lang, L., Khoze, V., Martin, A., & Ryskin, M. (2019). Searching for the odderon in ultraperipheral proton-ion collisions at the LHC. Physical Review D, 99(3), Article 034011. https://doi.org/10.1103/physrevd.99.034011

We explore the possibility of observing odderon exchange in proton-ion collisions at the LHC, via the ultraperipheral photoproduction of C-even mesons. As well as the signal, we consider in detail the principle backgrounds, due to QCD-initiated produ... Read More about Searching for the odderon in ultraperipheral proton-ion collisions at the LHC.

On the functoriality of Khovanov-Floer theories (2019)
Journal Article
Baldwin, J., Hedden, M., & Lobb, A. (2019). On the functoriality of Khovanov-Floer theories. Advances in Mathematics, 345, 1162-1205. https://doi.org/10.1016/j.aim.2019.01.026

We introduce the notion of a Khovanov–Floer theory. We prove that every page (after ) of the spectral sequence accompanying a Khovanov–Floer theory is a link invariant, and that an oriented link cobordism induces a map on each page which is an invari...

The critical greedy server on the integers is recurrent (2019)
Journal Article
Cruise, J. R., & Wade, A. R. (2019). The critical greedy server on the integers is recurrent. Annals of Applied Probability, 29(2), 1233-1261. https://doi.org/10.1214/18-aap1434

Each site of Z hosts a queue with arrival rate λ. A single server, starting at the origin, serves its current queue at rate μ until that queue is empty, and then moves to the longest neighbouring queue. In the critical case λ=μ, we show that the serv... Read More about The critical greedy server on the integers is recurrent.

Exclusive LHC physics with heavy ions: SuperChic 3 (2019)
Journal Article
Harland-Lang, L., Khoze, V., & Ryskin, M. (2019). Exclusive LHC physics with heavy ions: SuperChic 3. The European Physical Journal C, 79(1), Article 39. https://doi.org/10.1140/epjc/s10052-018-6530-5

We present results of the updated SuperChic 3 Monte Carlo event generator for central exclusive production. This extends the previous treatment of proton–proton collisions to include heavy ion (pA and AA) beams, for both photon and QCD-initiated prod...
