Integrable spin chain for the SL(2,R)/U(1) black hole sigma model.

Physical review letters

Ikhlef Y, Jacobsen JL, Saleur H.
PMID: 22463514
Phys Rev Lett. 2012 Feb 24;108(8):081601. doi: 10.1103/PhysRevLett.108.081601. Epub 2012 Feb 23.

We introduce a spin chain based on finite-dimensional spin-1/2 SU(2) representations but with a non-Hermitian "Hamiltonian" and show, using mostly analytical techniques, that it is described at low energies by the SL(2,R)/U(1) Euclidian black hole conformal field theory. This...

On the Role of Mentalizing Processes in Aesthetic Appreciation: An ERP Study.

Frontiers in human neuroscience

Beudt S, Jacobsen T.
PMID: 26617506
Front Hum Neurosci. 2015 Nov 13;9:600. doi: 10.3389/fnhum.2015.00600. eCollection 2015.

We used event-related brain potentials to explore the impact of mental perspective taking on processes of aesthetic appreciation of visual art. Participants (non-experts) were first presented with information about the life and attitudes of a fictitious artist. Subsequently, they...

Scalable 3D bicontinuous fluid networks: polymer heat exchangers toward artificial organs.

Advanced materials (Deerfield Beach, Fla.)

Roper CS, Schubert RC, Maloney KJ, Page D, Ro CJ, Yang SS, Jacobsen AJ.
PMID: 25753365
Adv Mater. 2015 Apr 17;27(15):2479-84. doi: 10.1002/adma.201403549. Epub 2015 Mar 05.

A scalable method for fabricating architected materials well-suited for heat and mass exchange is presented. These materials exhibit unprecedented combinations of small hydraulic diameters (13.0-0.09 mm) and large hydraulic-diameter-to-thickness ratios (5.0-30,100). This process expands the range of material architectures...

Why did the authors perform a meta-analysis of studies with primary endpoints they consider clinically unimportant?.

Anharmonic Vibrational Frequency Calculations Are Not Worthwhile for Small Basis Sets.

Journal of chemical theory and computation

Jacobsen RL, Johnson RD, Irikura KK, Kacker RN.
PMID: 26588738
J Chem Theory Comput. 2013 Feb 12;9(2):951-4. doi: 10.1021/ct300293a. Epub 2013 Jan 22.

Anharmonic calculations using vibrational perturbation theory are known to provide near-spectroscopic accuracy when combined with high-level ab initio potential energy functions. However, performance with economical, popular electronic structure methods is less well characterized. We compare the accuracy of harmonic...

Additive manufacturing of polymer-derived ceramics.

Science (New York, N.Y.)

Eckel ZC, Zhou C, Martin JH, Jacobsen AJ, Carter WB, Schaedler TA.
PMID: 26721993
Science. 2016 Jan 01;351(6268):58-62. doi: 10.1126/science.aad2688.

The extremely high melting point of many ceramics adds challenges to additive manufacturing as compared with metals and polymers. Because ceramics cannot be cast or machined easily, three-dimensional (3D) printing enables a big leap in geometrical flexibility. We report...

Duality relations for M coupled potts models.

Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics

Jacobsen JL.
PMID: 11088510
Phys Rev E Stat Phys Plasmas Fluids Relat Interdiscip Topics. 2000 Jul;62(1):R1-4. doi: 10.1103/physreve.62.r1.

We establish explicit duality transformations for systems of M q-state Potts models coupled through their local energy density, generalizing known results for M=1,2,3. The M-dimensional space of coupling constants contains a self-dual submanifold of dimension D(M)=[M/2]. For the case...

Monochromatic path crossing exponents and graph connectivity in two-dimensional percolation.

Physical review. E, Statistical, nonlinear, and soft matter physics

Jacobsen JL, Zinn-Justin P.
PMID: 12513543
Phys Rev E Stat Nonlin Soft Matter Phys. 2002 Nov;66(5):055102. doi: 10.1103/PhysRevE.66.055102. Epub 2002 Nov 19.

We consider the fractal dimensions d(k) of the k-connected part of percolation clusters in two dimensions, generalizing the cluster (k=1) and backbone (k=2) dimensions. The codimensions x(k)=2-d(k) describe the asymptotic decay of the probabilities P(r,R) approximately (r/R)(x(k)) that an...

Role of plant pathology in integrated pest management.

Annual review of phytopathology

Jacobsen BJ.
PMID: 15012529
Annu Rev Phytopathol. 1997;35:373-91. doi: 10.1146/annurev.phyto.35.1.373.

Integrated Pest Management (IPM) is a paradigm that is widely adopted by all pest control disciplines but whose early definitions and philosophical basis belong to entomologists. Plant pathology research and extension work has historically emphasized integration of several control...

Mechanisms for tolerating freeze-thaw stress of two evergreen chaparral species: Rhus ovata and Malosma laurina (Anacardiaceae).

American journal of botany

Pratt RB, Ewers FW, Lawson MC, Jacobsen AL, Brediger MM, Davis SD.
PMID: 21646132
Am J Bot. 2005 Jul;92(7):1102-13. doi: 10.3732/ajb.92.7.1102.

The response to freeze-thaw stress was examined for two co-occurring evergreen species, Malosma laurina and Rhus ovata. Laboratory and field experiments on adults and seedlings were made in the spring and winter in 1996 and again on adults in...
