This letter proposes a co-designed millimeter-wave (mm-wave) and sub-6GHz antenna system. The antenna system consists of four 28GHz mm-wave arrays with reconfigurable radiation patterns and two sub-6GHz antennas fed with two corner capacitive coupling elements (CCEs). Each corner CCE is formed by the connected ground planes of two mm-wave arrays in the shared-aperture configuration. The two CCEs a

Sufficiency has long been marginalized in the public and political sustainability discourse. Since attempts to reduce CO2 emissions in the long term have so far fallen short of expectations, sufficiency has recently approached the forefront of scientific and social debates about a »good life«. In addition to a strict reduction target, the sufficiency strategy promises psychological well-being and

With stringent effluent requirements and the implementation of new processes for micropollutant removal, it is increasingly important for wastewater treatment plants (WWTPs) to understand the factors affecting effluent quality. Phages (viruses infecting prokaryotes) are abundant in the biological treatment processes. They can contribute to organic carbon in the treated effluent both because they a

BACKGROUND: Although the impact of pancreatic infections in acute pancreatitis has been studied extensively, there are no population-based data on extrapancreatic infections and their potential relation to organ failure. We aimed to study the occurrence of pancreatic and extrapancreatic bacterial infections in acute pancreatitis and their relation to patient outcome. PATIENTS AND METHODS: All pati

Ants use memorized visual scenes to navigate towards food sources and to return to their nest. Two new studies show that both of these behaviors fail when structures of the ant brain known as mushroom bodies are chemically disrupted, confirming long-held assumptions about the location of ants’ visual navigation memories.

It is generally found that human capital has had positive effects on industrial development and economic growth, but the relationship between formal education, work practice, industrial development and economic growth, and the relationships between them over time, remains unclear, largely because of a lack of empirical evidence. This note argues that an investigation of the Danish dairy industry c

Background:The Mediterranean diet (MD) has been proposed as a means for cancer prevention, but little evidence has been accrued regarding its potential to prevent pancreatic cancer. We investigated the association between the adherence to the MD and pancreatic cancer risk within the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort.Methods:Over half a million participants

Objective To systematically identify and validate published colorectal cancer risk prediction models that do not require invasive testing in two large population-based prospective cohorts. Design Models were identified through an update of a published systematic review and validated in the European Prospective Investigation into Cancer and Nutrition (EPIC) and the UK Biobank. The performance of th

En redogörelse av en enkel undersökning som visar att en övervägande majoritet av de tillfrågade föredrar en mer klassisk version av byggnad i centrala Helsingborg framför den modernistiska som förverkligas.

En reflektion kring ett politiskt beslut som togs i Göteborg 2020. Politikerna kom överens om att nu måste det nya som byggs vid Skeppsbron i Göteborg få en klassisk utformning. De menar att med klassisk och traditionell arkitektur blir invånarna och besökare nöjdare. Beslutet retade upp många arkitekter.

En reflektion kring värdet av en attraktiv stadskärna i tider

In this article we review the legal regulation of an obligation to self-isolate in Ukraine. For the period from 22 April 2020 till 22 June 2020 four groups of persons were obliged to self-isolate due to COVID-19. These groups are: persons diagnosed with or suspected to have COVID-19, persons that have been in contact with those diagnosed with COVID-19, those who consented to self-isolation when en

Soil contamination is a widespread problem and actions need to be taken in order toprevent damage to the groundwater and the life around the contaminated sites. InSweden more than 80.000 sites are potentially contaminated, therefore there is ademand for accurate and efficient methods for site characterization and soilremediation. In the past, the preferred methodology for soil remediation involved

Modern subtractive and additive manufacturing techniques present new avenues for X-ray optics with complex shapes and patterns. Refractive phase plates acting as glasses for X-ray optics have been fabricated, and spherical aberration in refractive X-ray lenses made from beryllium has been successfully corrected. A diamond phase plate made by femtosecond laser ablation was found to improve the Stre

Human activity is a major driver of change and has contributed to many of the challenges we face today. Detailed information about human population distribution is fundamental and use of freely available, high-resolution, gridded datasets on global population as a source of such information is increasing. However, there is little research to guide users in dataset choice. This study evaluates five
