Entropy of causal diamond ensembles
SciPost Physics, 2023 We define a canonical ensemble for a gravitational causal diamond by introducing an artificial York boundary inside the diamond with a fixed induced metric and temperature, and evaluate the partition function using a saddle point approximation.

On the eigenvalues of a class of saddle point matrices [PDF]
Numerische Mathematik, 2006 We study spectral properties of a class of block 2 × 2 matrices that arise in the solution of saddle point problems. These matrices are obtained by a sign change in the second block equation of the symmetric saddle point linear system. We give conditions for having a (positive) real spectrum and for ensuring diagonalizability of the matrix.

AFM‐Based Functional Tomography – To Mill or Not to Mill, that is the Question!
Advanced Materials Interfaces, EarlyView.Complex networks of conducting domain wall interfaces exist hidden underneath the surface of ferroelectric hexagonal manganites. It reveals the morphology and conductive properties directly by 3D tomographic atomic force microscopy. It correlates the measured surface level conductance with subsurface domain wall structure, and discuss the existence ...

Nonanalyticities of the entropy induced by saddle points of the potential energy landscape [PDF]
J. Stat. Mech. Theory Exp., P04025 (2008), 2008 The relation between saddle points of the potential of a classical many-particle system and the analyticity properties of its Boltzmann entropy is studied. For finite systems, each saddle point is found to cause a nonanalyticity in the Boltzmann entropy, and the functional form of this nonanalytic term is derived for the generic case of potentials ...

Unveiling Multi‐Scale Architectural Features in Single‐Cell Hi‐C Data Using scCAFE
Advanced Science, EarlyView.scCAFE is a deep learning framework designed to identify multi‐scale 3D genome architectural features from single‐cell Hi‐C data without dense imputation. It predicts chromatin loops, TAD‐like domains, and A/B compartments, enabling efficient characterization of organization at the single‐cell level. scCAFE also identifies marker loop anchors, offering

Ferrocene derivatives with planar chirality and their enantioseparation by liquid‐phase techniques
ELECTROPHORESIS, Volume 44, Issue 1-2, Page 158-189, January 2023., 2023 Abstract In the last decade, planar chiral ferrocenes have attracted a growing interest in several fields, particularly in asymmetric catalysis, medicinal chemistry, chiroptical spectroscopy and electrochemistry. In this frame, the access to pure or enriched enantiomers of planar chiral ferrocenes has become essential, relying on the availability of ...
