In this paper, we study the trade-off between complexity and performance in massive MIMO systems with neural-network based digital pre-distortion (NN-DPD) blocks at the base station. In particular, we consider a multi-user massive MIMO system with per-antenna NN-DPDs, each with an adjustable NN architecture in terms of the size and the number of NN hidden layers. We first analyze the system perfor

To understand the mechanisms of economic resilience, we have studied how sectoral proximity relates to the regional capability to transform and recover from a shrinking crisis. Through a comparative study of Irish regions, a proximity analysis provided evidence that the majority of new sectors in the recovering region developed in proximity to the region’s leading sector. This leads to the conclus

The article examines the ideology of improvement in the context of seventeenth- and eighteenth-century mining in northern Sweden in the province of Sápmi. It discusses how the rhetoric of improvement and “civilizing” projects were intertwined with the mining enterprises; how they informed the regulatory and disciplinary ordinances issued for the region; and how the ideas of reform, discipline, and

Propolis is a resin-like material produced by bees from the buds of poplar and cone-bearing trees and is used in beehive construction. Propolis is a common additive in various biocosmetics and health-related products, despite the fact that it is a well-known cause of contact allergy. Caffeic acid and its esters have been the primary suspects behind the sensitization potency of propolis-induced con

The post examines connections between global North, and particularly European, efforts to address climate- and disaster-related displacement in climate vulnerable countries, and the externalization policies implemented by those same countries to prevent refugee and migratory movements.

The work focuses on analysis and development of integrated low-pressure shaft generator in a geared twin-spool turbofan engine. It starts with manufacturing and evaluation of direct cooled hollow conductor coils, and has focus manufacturing, assembling and integration issues essential to machine design. The experiment-in-loop, but the model-based evaluation focuses not only on the coolant and cool

HIV-2 infection will progress to AIDS in most patients without treatment, albeit at approximately half the rate of HIV-1 infection. HIV-2 capsid (p26) amino acid polymorphisms are associated with lower viral loads and enhanced processing of T cell epitopes, which may lead to protective Gag-specific T cell responses common in slower progressors. Lower virus evolutionary rates, and positive selectio

Indigenous women suffer wide discrimination, exploitation and victimization in their societies. This study focuses on the experiences a group of Aymara women have of violence and discrimination, and what strategies they use to cope with these oppressive acts. Semi-structured interviews were conducted with 15 Aymara women living in the city of El Alto in the country of Bolivia. The theoretical fram

On June 24th 2022, nearly two thousand people attempted to cross the border between Morocco and the Spanish enclave of Melilla, resulting in dozens of deaths and injuries. Scholars have suggested that these border crossings in the Mediterranean highlight the systemic border violence that is exercised towards migrants in the region to prevent presenting them as isolated or sporadic. To contribute t

Addressing representations of Russia and neighbouring Eastern Europe in post-1989 Nordic cinemas, this ground-breaking volume investigates their hitherto-overlooked transnational dimension. Departing from the dark stereotypes that characterise much of ‘Eastern noir’, the author presents Russia and Eastern Europe as imagined spaces depicted with a surprisingly rich, but previously neglected, cinema

Shape control strategies seek to bring deformable objects towards a desired target shape. However, conventional methods focus on reaching the target shape without considering the extent to which the object is deformed during the control process. Control actions may generate unnecessary deformations and thus, increase the possibility of object over-stressing and failure. In this letter, we tackle t

Closed-loop motion planning is suitable for obstacle avoidance in dynamically changing environments due to its reactive nature, and various methods have been presented to provide (almost) global convergence. A common assumption in the control design is that the robot operates in a disjoint star world, i.e., all obstacles are strictly starshaped and mutually disjoint. However, in real-life scenario

In this article I investigate the spatial development of Swedish district courthouses and their different room types from 1970 to 2020, with attention to the specificities and commonalities with other building types. How have spatial form and use travelled between building types during this period, and how has this contributed to the recent, quite radical developments and transformation of the cou
