Planners as Gatekeepers: Spatial Justice Through the lens of Planning Theory in Helsinki
Abstract Planning practice is a device of controlling land use and ideally corresponds to societal demands. It can contribute to spatial justice through its two roles, substantive and procedural. Planning theory, on the other hand, studies both roles of planning practice focusing on the interplay of power.

A General and Efficient Framework for the Rapid Design of Miniaturized, Wideband, and High‐Bit RIS
A general and efficient framework is proposed for the rapid design of high‐performance reconfigurable intelligent surfaces (RISs). This framework integrates advanced antenna design techniques and incorporates various load types, quantities, and values to achieve the design of high‐performance RISs.

Conformal Reconfigurable Intelligent Surfaces: A Cylindrical Geometry Perspective
Cylindrical reconfigurable intelligent surfaces are explored for low‐complexity beam steering using one‐bit meta‐atoms. A multi‐level modeling approach, including optimization‐based synthesis, demonstrates that even minimal hardware can support directive scattering.

Updatable Closed‐Form Evaluation of Arbitrarily Complex Multiport Network Connections
The inverse design of electrically large wave devices often uses reduced‐order multiport models with discrete optimization, requiring many evaluations of complex interconnections between subsystems that differ only in a few blocks. This paper introduces a closed‐form framework enabling efficient Woodbury low‐rank updates of related, previous ...

Gel‐Amin for Improving Extracellular Recordings of Cardiomyocytes in a 3D Microphysiological System
This work combines a conductive collagen‐based hydrogel with a laser‐cut and assembly technique to fabricate microphysiological systems that improve extracellular recordings of cardiomyocytes in 3D on microelectrode arrays. The inclusion of choline acrylate into GelMA imparts a higher electrical conductivity and improves the signal‐to‐noise ratio of on‐

Carrots for Vetogates: Incentive Systems to Promote Capital Market Gatekeeper Effectiveness
This Article contributes a novel idea to the literature on capital market gatekeepers: positive incentive systems for gatekeepers to perform functions not required of them in exchange for rewards if they perform the functions successfully. Capital market

Exceptional Antimodes in Multi‐Drive Cavity Magnonics
Driven‐dissipative cavity‐magnonics provides a flexible platform for engineering non‐Hermitian physics such as exceptional points. Here, using a four‐port, three‐mode system with controllable microwave interference, antimodes and coherent perfect extinction (CPE) are realized, enabling active tuning to antimode exceptional points.

A compact QASRR‐based THz metamaterial absorber enables polarization‐insensitive dual‐band absorption and skin‐cancer‐related refractive‐index sensing through measurable resonance shifts. Field, surface‐current, and circuit analyses clarify the dual‐resonance mechanism, while StackNet‐assisted prediction accurately estimates the simulated absorption ...

This paper introduces the Gatekeeper Dynamic as a modern extension of Kurt Lewin’s Gatekeeping Theory, redefined for digital advertising ecosystems. It explains how platforms such as Google retain advertising spend within their own environments by controlling audience attention, data, and measurement tools. Alphabet’s advertising channels are used as a
