Gateways, Funnels, and Stackers: How People Hide Property Ownership Through Offshore Structures

open access: yesThe British Journal of Sociology, EarlyView.
ABSTRACT How do wealthy individuals use offshore financial structures like shell companies to protect personal assets? And how is such offshore wealth structuring itself variably organized? Moving beyond conceptualizations of offshore as concerning only individual tax havens, this article investigates offshore wealth structuring as a fundamentally ...

A novel hybrid method based MPP tracking design using boost converter for solar power systems [PDF]

open access: yes
The convergence time is one of the key parameters for evaluating the energy conversion efficiency of PV power systems in the experimental process of tracking the maximum power point (MPP) in real-time. When the PV system is partially shaded, for example,

Evaluating and Advancing the Use of Shore‐Based Observers for Scientific Sampling and Catch Verification in High‐Volume Fisheries

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Shore‐based observers are increasingly being used in place of at‐sea observers to monitor and sample commercial fisheries catch. However, few evaluations assess whether these programs meet their stated goals or how to optimize them, and industry data are rarely tested for accuracy despite serving as the foundation for catch accounting. Using a

An adapted model predictive control MPPT for validation of optimum GMPP tracking under partial shading conditions

open access: yesScientific Reports
The energy generation efficiency of photovoltaic (PV) systems is compromised by partial shading conditions (PSCs) of solar irradiance with many maximum power points (MPPs) while tracking output power.

Power optimization in partially shaded photovoltaic systems [PDF]

open access: yes, 2018
The Power-Voltage characteristic of a photovoltaic (PV) array exhibits non-linear behaviour when exposed to uniform solar irradiance. Maximum Power Point (MPP) tracking is challenging due to the varying climatic conditions in a solar PV system. Moreover,

One‐Step Coaxial 3D Printing of Pre‐Vascularized Skin Organoid Models with ADSC Microspheres for Enhanced Wound Healing

open access: yesAdvanced Science, Volume 13, Issue 9, 13 February 2026.
A multifunctional vascular bed platform is created using coaxial 3D printing, allowing the one‐step integration of organoid microspheres with perfusable vascular structures. This strategy enables rapid and functional vascularization of organoids to support tissue repair and vascularization, providing a scalable and translationally promising approach ...
