A microstrip antenna integration with a power amplifier is presented for the 60 GHz band. The antenna is a single layer 4×4 square patches array. The power amplifier is injection locked, designed in a 65 nm CMOS technology, with single-ended input and output signals. The integration is realized by means of bond wire connections. The antenna and the power amplifier are fabricated, characterized and

Mosaddeq’s preoccupation with the nationalization of Iran’s oil sector derived from his belief that such a venture, once realized, could bring economic prosperity, national autonomy and political sovereignty in its wake. The loss of Abadan Oil Refinery as a result of action by the Iranian nationalists also dealt Britain’s imperial prestige a stinging blow at a time when it was struggling to adapt

Many homes in affluent Western societies have an ongoing battle against domestic mess, because of the steady inflow of new acquisitions. This essay looks at the ways in which mess has travelled through modern history and has ended up as both a powerful metaphor and a constant everyday worry in consumer life. In this process, mess has often been defined as a problematic condition, often reflecting

We propose and analyze a novel scheme based on LDPC codes for quantitative group testing. The key underlying idea is to augment the bipartite graph by introducing hidden non-binary variables to strengthen the message-passing decoder. This is achieved by grouping items into bundles of size q within the test matrix, while keeping the testing procedure unaffected. The decoder, inspired by some works

The purpose of this research is to examine the integration of Syrian refugees in Egypt, focusing on their individualized experiences in navigating opportunities and building their lives. Through in-depth semi-structured interviews with Syrian refugees residing in Cairo, this study examines their everyday lives, uncovering the multifaceted challenges they encounter and the various tactics they empl

In a wireless communication system, the radio propagation channel is a complicated component to characterise. Channel sounding equipment thus has to meet specific criteria to extract the desired channel parameters. In this study, the authors outline the development and validation of a vector network analyser (VNA) based channel sounder for the frequency range from 1 to 50 GHz using radio-over-fibr

We revisit a Swedish comprehensive school reform first evaluated by Meghir and Palme (2005). This reform increased years of schooling and abolished tracking. We extend the original analysis to the full population and introduce an improved education measure. Our results confirm the original overall finding of small average earnings effects. However, we find considerably larger increases in educatio

Wear mechanisms and failure modes were investigated for autoclave-cured, woven carbon fiber-reinforced polymer (CFRP) composite gears in a mesh with a surface-hardened, 42CrMo4 steel pinion. The reference gears (m = 1 mm, b = 2 mm, z = 20) were tested at torque levels ranging from 0.4 Nm to 0.8 Nm. The temperature was monitored with a thermographic camera, while the gear damage and wear volume wer

Patients with immune-mediated kidney diseases are at increased risk of severe coronavirus disease 2019 (COVID-19). The international rollout of COVID-19 vaccines has provided varying degrees of protection and enabled the understanding of vaccine efficacy and safety. The immune response to COVID-19 vaccines is lower in most patients with immune-mediated kidney diseases; either related to immunosupp
