Grand unification through gravitational effects [PDF]

, 2010
We systematically study the unification of gauge couplings in the presence of (one or more) effective dimension-5 operators cHGG/4MPl, induced into the grand unified theory by gravitational interactions at the Planck scale MPl.

Optimality in Goal-Dependent Analysis of Sharing

, 2009
We face the problems of correctness, optimality and precision for the static analysis of logic programs, using the theory of abstract interpretation.

Gauge Coupling Unification via A Novel Technicolor Model

, 2006
We show that the recently proposed minimal walking technicolor theory together with a small modification of the Standard Model fermionic matter content leads to an excellent degree of unification of the gauge couplings.

Determining Heavy Mass Parameters in Supersymmetric SO(10) Models [PDF]

, 2007
Extrapolations of soft scalar mass parameters in supersymmetric theories can be used to explore elements of the physics scenario near the grand unification scale.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

From Aesthetic Virtues to God:

TheoLogica, 2023
I argue that the aesthetic theoretical virtues of beauty, simplicity, and unification, as well as the evidential virtue of explanatory depth, can transform theistic-friendly personal cause (PC) arguments—like the kalām cosmological argument (KCA) and ...

Unification and Logarithmic Space [PDF]

, 2014
We present an algebraic characterization of the complexity classes Logspace and NLogspace, using an algebra with a composition law based on unification.

Order-sorted feature theory unification

The Journal of Logic Programming, 1997
Order-sorted feature (OSF) terms provide an adequate representation for objects as flexible records. They are sorted, attributed, possibly nested, structures, ordered thanks to a subsort ordering. Sort definitions offer the functionality of classes imposing structural constraints on objects.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)
