Geometry of strongly minimal hybrids of fragments of theoretical sets [PDF]

, 2023
In this article, strongly minimal geometries of fragment hybrids are considered. In this article, a new concept was introduced as a family of Jonsson definable subsets of the semantic model of the Jonsson theory T, denoted by JDef(CT ).

The properties of central types with respect to enrichment by Jonsson set

Қарағанды университетінің хабаршысы. Математика сериясы, 2017
The main results of the article are for a new class of theories, namely existential prime strongly convex Jonsson theories. This class is quite broad in terms of algebra, for example it includes the class of all Abelian groups and groups.

Companions of the fragments in the Jonsson enrichment

Қарағанды университетінің хабаршысы. Математика сериясы, 2017
In this article we consider the properties of central types for the existentially prime strongly convex Jonsson theories in some extension. This class of theories is a subclass of a broad class of Jonsson theories.

The properties of central-orbital types of EPSCJ theories

Қарағанды университетінің хабаршысы. Математика сериясы, 2017
This article, in its content, refers to the study of the theoretical - model properties of the Jonsson theories. A new approach to this study is proposed. As a new notion, the idea of a central - orbital type is used.

Peptide fingerprinting of Alzheimer's disease in cerebrospinal fluid: identification and prospective evaluation of new synaptic biomarkers [PDF]

, 2011
<p><b>Background:</b> Today, dementias are diagnosed late in the course of disease. Future treatments have to start earlier in the disease process to avoid disability requiring new diagnostic tools.

Exploring Supply Chain Visibility for Circularity: A Delphi Approach

Business Strategy and the Environment, EarlyView.
ABSTRACT Circular supply chains (CSCs) depend on enhanced supply chain visibility (SCV) to track and manage resource flows and thereby enable efficient decision‐making. Despite confronting silo mentalities, fragmented information, technological barriers, resistance to change, and a lack of standardization, data sharing remains crucial for SCV and ...

Enabling Factors for the Shift From ESG Scores to ESG Performance Management System in SMEs: An Interventionist Approach

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines how small and medium‐sized enterprises (SMEs) transition from a symbolic, disclosure‐oriented ESG logic toward a substantive ESG‐oriented performance management system (PMS) grounded in actionable KPIs. Drawing on evidence from the Apuan‐Versilian Stone Industrial District through an interventionist research design, we ...

A new, ~4500‐year varve record and high‐resolution tephrochronology from lake Hämälänlampi, eastern Finland, provides age constraints for the Furnas C and the Glen Garry/Askja A‐2000 eruptions

Journal of Quaternary Science, EarlyView.
ABSTRACT The northern European distal cryptotephra framework is constantly developing both in terms of identification of new tephra horizons and improved age constraints for the already well‐established tephra marker horizons. However, many prehistoric tephra layers have only been dated by the radiocarbon method, with its inherent problems.

Failure in Motion: A Framework for Capability Erosion and Institutional Dysfunction

Strategic Change, EarlyView.
ABSTRACT Drawing on the literature on capability erosion and institutional dysfunction (ID), this study develops a conceptual framework that sheds new light on how the interaction between capability erosion and ID creates conditions for business failure across borders. By articulating two dimensions of heterogeneous capability and resource erosion (i.e.
