Journal of Algebra, 2008 Let \(R\) be a polynomial ring in \(n\) variables over a field \(k\) with standard grading and let \(I\subseteq R\) be a homogeneous ideal of codimension \(h\). Consider the graded minimal free \(R\)-resolution of \(R/I\): \[ 0\to \bigoplus R(-j)^{\beta_{p,j}}\to \dots \to \bigoplus R(-j)^{\beta_{1,j}}\to R\to R/I\to 0.

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading
Advanced Engineering Materials, EarlyView.The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

SUBSTANTIATION OF SURGICAL APPROACH IN IATROGENIC INJURIES OF THE BILE-EXCRETING DUCTS
Вестник хирургии имени И.И. Грекова, 2015 The results of examination and treatment were analyzed in 51 patients with iatrogenic injuries of the bile-excreting ducts. Patients were divided into 5 groups according to international classification (EAES, 2013).

On Chern ratios for surfaces with ample cotangent bundle
Le Matematiche, 2006 In this paper we study the problem of density in (1, 3) for the Chern ratio of surfaces with ample cotangent bundle. In particular we prove density in (1, 2) by constructing a family of complete intersection surfaces in a product of varieties with big ...

Advanced Functional Materials, EarlyView.Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...

Advanced Functional Materials, EarlyView.Guided by the golden ratio, a class of aperiodic architected metamaterials is introduced to address the intrinsic trade‐off between strength and toughness. By unifying local geometric heterogeneity with global order, the golden‐ratio‐guided aperiodic architecture promotes spatial delocalization of damage tolerence regions, leading to more tortuous ...

Euler classes and complete intersections
Kyoto Journal of Mathematics, 1996 Among other things, the authors consider the following question: Let \(A\) be a noetherian ring with \(\dim A=n\). Let \(I\subseteq A[t]\) be an ideal such that \(\dim A [t]/I=1\). Let \(P\) be a projective \(A\)-module of rank \(n\). Suppose \(f:P\to I(0)\) is a surjective map. Assume that there exists a surjection \(\varphi:P[t]/IP[t]\to I/I^2\) such
