Do Family Changes Constitute a Comprehensive Demographic Shift? A Comparison of the Spatial Dynamics of Five Family Changes in Switzerland (1969–2023)

Tijdschrift voor Economische en Sociale Geografie, EarlyView.
Abstract Several theories have been proposed to explain the family changes that have occurred in Europe since the mid‐1960s. It is often assumed that as these changes occurred simultaneously; they have a common origin and represent the same demographic shift.

Dielectric Relaxation, Water Sorption Thermodynamics, and Humidity‐Sensing Mechanisms of Compressed Ulva Biomass Pellets

Applied Research, Volume 5, Issue 6, December 2026.
This study investigates the moisture sorption thermodynamics, dielectric relaxation behavior, and humidity‐sensing performance of compressed Ulva biomass pellets. The findings demonstrate that sustainable macroalgal pellets provide low hysteresis (~1.63%) and wide‐range sensitivity for green environmental diagnostics.

A New Optimization Problem in FSO Communication System [PDF]

IEEE Communications Letters, 2018
According to the physical phenomena of atmospheric channels and wave propagation, performance of wireless communication systems can be optimized by simply adjusting its parameters. This way is more economically favorable than consuming power or using processing techniques.

There Is Always a Bigger Fish. Determinants of Power Perceptions in Swiss Biodiversity Policy

Policy Studies Journal, Volume 54, Issue 4, November 2026.
ABSTRACT The Advocacy Coalition Framework (ACF) views power as crucial in policy processes, but the nature of coalition power, its determinants, and how to empirically measure it remain understudied. In this article, we use a mixed method approach and social network analysis to explore power relationships in the biodiversity policy subsystem in ...

Importance of noise models in FSO communications [PDF]

EURASIP Journal on Wireless Communications and Networking, 2014
يعد الاتصال البصري الفضائي الحر (FSO) تقنية ناشئة توفر نطاقًا تردديًا هائلاً وطيفًا بدون ترخيص ووصلة آمنة للغاية. تُستخدم الثنائيات الضوئية للانهيار الجليدي (APD) عادةً للكشف عن إشارات FSO عالية السرعة، حيث تُظهر الضوضاء توزيع الضوضاء الغاوسية المعتمدة على الإشارة (SDGN) بدلاً من توزيع الضوضاء الغاوسية المستقلة عن الإشارة (الإشارة).

The cranial, mandibular, and hyoid anatomy of softshell turtles (Trionychidae): A revised character list for phylogenetic analysis

The Anatomical Record, Volume 309, Issue 10, Page 2790-2837, October 2026.
Abstract Softshell turtles (Pan‐Trionychidae) are an early branching clade of hidden‐necked turtles (Cryptodira) with a rich fossil record extending back to the Early Cretaceous. The evolutionary history of softshell turtles is still unresolved because of their conservative morphology combined with high levels of polymorphism related to morphological ...
