Acta Crystallographica Section D, Volume 81, Issue 12, Page 734-757, December 2025.We present a protocol to detect and characterize questionable backbone conformations in X‐ray protein structure models. These conformations may arise from artifacts related to the crystallization process or from errors introduced during model building and refinement.

Vector and tensor perturbations in Horava-Lifshitz cosmology
, 2010 We study cosmological vector and tensor perturbations in Horava-Lifshitz gravity, adopting the most general Sotiriou-Visser-Weinfurtner generalization without the detailed balance but with projectability condition.

On Models of New Physics for the Tevatron Top A_FB [PDF]
, 2011 CDF has observed a top forward-backward asymmetry discrepant with the Standard Model prediction at 3.4 \sigma. We analyze models that could generate the asymmetry, including flavor-violating W's, horizontal Z'_Hs, triplet and sextet diquarks, and ...

Acta Crystallographica Section D, Volume 81, Issue 12, Page 718-733, December 2025.A surface‐entropy reduction approach for human Polo‐like kinase 1 (PLK1) enabled a reproducible and robust crystallization system for this cancer drug target. Co‐crystal structures with representatives of three different small‐molecule inhibitor classes were elucidated.

Completion of partial structures using Patterson maps with the CrysFormer machine‐learning model
Acta Crystallographica Section D, Volume 81, Issue 12, Page 668-677, December 2025.We integrate existing machine learning‐based protein structure‐prediction methods with X‐ray crystallography by completing partial structures derived from AlphaFold predictions and the corresponding Patterson map information. The CrysFormer results are promising when applied to an initial data set of 15‐residue fragments in P21 unit cells.Protein ...

On mass limit for chiral color symmetry $G'$-boson from Tevatron data on $t \bar{t}$ production
, 2010 The contributions of $G'$-boson predicted by the chiral color symmetry of quarks to the cross section $\sigma_{t\bar{t}}$ and to the forward-backward asymmetry $A_{\rm FB}^{p \bar p}$ of $t\bar{t}$ production at the Tevatron are calculated with account ...

Reconstructing biological molecules with help from video gamers
Acta Crystallographica Section D, Volume 81, Issue 11, Page 598-604, November 2025.The results of the Foldit citizen science puzzles for crystallographic models and their integration into the PDB‐REDO databank are discussed.Foldit is a citizen science video game in which players tackle a variety of complex biochemistry puzzles. Here, we describe a new series of puzzles in which Foldit players improve the accuracy of models in the ...

Non-Gaussianity Consistency Relation for Multi-field Inflation
, 2011 While detection of the "local form" bispectrum of primordial perturbations would rule out all single-field inflation models, multi-field models would still be allowed.

Cryo‐EM single‐particle analysis expanding towards increasingly native samples
Acta Crystallographica Section D, Volume 81, Issue 11, Page 587-597, November 2025.Cryo‐EM single‐particle analysis has revolutionized structural biology by allowing high‐resolution analysis of large molecular assemblies that are not amenable to crystallography or NMR. Combination of this technology with innovative sample‐preparation protocols further expands the range of potential targets.The explosion of cryo‐electron microscopy ...
