Nonlocal active sound control for composite regions

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
In the active sound control problem, additional sound sources, known as control sources, are implemented at the perimeter of a protected domain. The control sources can generate secondary sound inside the shielded domain, which attenuates incoming noise. This leads to an inverse source problem.

Influence of porosity and architecture on the mechanical and acoustic properties of FFF‐printed PLA structures

open access: yesPolymer International, EarlyView.
The influence of porosity and infill pattern (architecture) on the mechanical and acoustic properties of FFF‐printed PLA is investigated. Ultrasonic analysis highlights the dominant role of interlayer porosity, revealing anisotropic behavior and a transition in elastic properties with increasing porosity.

Carbon VIX, Climate Risk and Financial Stability New Evidence From Developing Countries

open access: yesSustainable Development, EarlyView.
ABSTRACT This study investigates the effects of the carbon VIX and climate risk on financial stability through the banking Z‐score in developing economies. Using the Dynamic Panel Threshold Model of 106 developing countries from 2012 to 2022, the results reveal that both carbon VIX and climate risk exert a significant negative influence on banking ...

Performance and Implication Analysis of Sound Insulation and Ventilation of Trickle Ventilators

open access: yesBuildings
Indoor environmental quality (IEQ), influenced by ventilation and acoustic conditions, directly affects human health and comfort. Existing studies often concern either ventilation or sound insulation alone, neglecting the impact of the trickle ventilator'

National Policy Coherence Counts for Reducing Inequality in Global Climate and Development Agendas

open access: yesSustainable Development, EarlyView.
ABSTRACT International institutions promote policy coherence as crucial to the effective and fair implementation of global sustainability agendas, though the evidence for its benefits is slim. We present here the first systematic cross‐country dataset on the consequences of national government efforts to promote policy coherence for vulnerable groups ...
