Many-Body Contributions to Green's Functions and Casimir Energies
, 2011 The multiple scattering formalism is used to extract irreducible N-body parts of Green's functions and Casimir energies describing the interaction of N objects that are not necessarily mutually disjoint.

Lifshitz Transition in Correlated Topological Semimetals
Advanced Science, Volume 13, Issue 31, 4 June 2026.Theoretical calculations reveal that in YPtBi and GdPtBi, strong electronic correlations shift topological Dirac nodes away from the Fermi level by forming large hole pockets. This effect is sensitive to temperature and arises from interactions among 4d or 4f electrons, offering insights into Fermi surface engineering in quantum materials.

Esophageal hiatal hernia: A report of two cases
The Journal of Association of Chest PhysiciansHiatal hernia (HH) is a condition in which an intraabdominal organ herniates through the esophageal hiatus of the diaphragm. It is rare in the pediatric population due to congenital defects in the diaphragm.

Join-irreducible Boolean functions
, 2009 This paper is a contribution to the study of a quasi-order on the set $\Omega$ of Boolean functions, the \emph{simple minor} quasi-order. We look at the join-irreducible members of the resulting poset $\tilde{\Omega}$.

Indagationes Mathematicae, 1994 Consider an \(n\times n\)-system of linear differential equations \(dY/dz= AY\) with \(A\in M_n (\mathbb{C} (z))\) and \(Y= (y_1, \dots, y_n)^t\) the vector of unknown locally complex analytic functions. In proving transcendence of the values of solutions at algebraic points Shidlovskij introduced the concept of (Shidlovskij) irreducibility. The system

Advanced Science, EarlyView.Whole‐genome analysis of 1,054 chickens reveals three ancestral sources (NWC, SYA, and SHF) with distinct temporal entry patterns into the Tibetan Plateau. Route‐specific selection scans, calibrated against a demographic null, suggest complementary functional enrichments—vascular homeostasis (NWC), calcium signaling and cardiac adaptation (SYA), and ...

Strong monotonicity for analytic ordinary differential equations
Electronic Journal of Differential Equations, 2009 We present a necessary and sufficient criterion for the flow of an analytic ordinary differential equation to be strongly monotone; equivalently, strongly order-preserving.

Scientific Journal of Informatics, 2020 An irreducible polynomial is one of the main components in building an S-box with an algebraic technique approach. The selection of the precise irreducible polynomial will determine the quality of the S-box produced. One method for determining good S-box

Invariants, Projection Operators and $SU(N)\times SU(N)$ Irreducible Schwinger Bosons
, 2011 We exploit SU(N) Schwinger bosons to construct and analyze the coupled irreducible representations of $SU(N) \times SU(N)$ in terms of the invariant group. The corresponding projection operators are constructed in terms of the invariant group generators.

Irreducible Decomposition of Curves
Journal of Symbolic Computation, 2002 This paper describes an algorithm for computing all irreducible components of a (not necessarily reduced) algebraic curve \(\mathcal C\) defined over \(\mathbb Q\) and embedded in a space of arbitrary dimension. The classical procedure is to take a generic projection of the curve to a plane and factorize the equation of the plane projection.
