Basic Demographic Processes in Croatia [PDF]

open access: yes, 2005
U radu se razmatraju glavni demografski procesi u suvremenom razvoju hrvatskog stanovništva: ukupna, prirodna i emigracijska depopulacija i demografsko starenje. Objašnjava se međusobna kauzalnost procesa opće i parcijalne depopulacije. Rezultati upućuju

Magnetic‐Field Tuning of the Spin Dynamics in the Quasi‐2D Van der Waals Antiferromagnet CuCrP2S6

open access: yesAdvanced Functional Materials, Volume 36, Issue 5, 15 January 2026.
This study reveals 2D character of the spin dynamics in CuCrP2S6, as well as complex field dependence of collective excitations in the antiferromagnetically ordered state. Their remarkable tuning from the antiferromagnetic to the ferromagnetic type with magnetic field, together with the non‐degeneracy of the magnon gaps favorable for the induction of ...

Sigma models for genuinely non-geometric backgrounds [PDF]

open access: yes, 2015
The existence of genuinely non-geometric backgrounds, i.e. ones without geometric dual, is an important question in string theory. In this paper we examine this question from a sigma model perspective.

Engineering Volumetric Tissue Analogs via Assembly of Endothelial Cell‐Covered Spheroidal Microtissues

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 2, 14 January 2026.
An engineering strategy to fabricate highly vascularized volumetric tissues with capillary networks is developed. Endothelial cell‐covered spheroidal microtissues with high structural integrity are efficiently produced using bioprinting technology. These spheroidal microtissues are then assembled and cultured under perfusion conditions, resulting in ...

Slum‐Based CAV Networks: Networking in Unyielding Poverty Situations

open access: yesStrategic Change, Volume 35, Issue 1, Page 115-128, January 2026.
ABSTRACT Over a billion of the world's population reside in slums. However, the configurations of their social and structural ties in these environments remain unsubstantiated. Drawing on a psychosociological rational choice perspective, we introduce theoretical explanations distinguishing slum dwellers' behavior, actions, and attitudes in community ...
