Among the existing estimators of factor-augmented regressions, the CCE approach is the most popular. A major reason for this popularity is the simplicity and good small-sample performance of the approach, making it very attractive from an empirical point of view. The main drawback is that most of the available asymptotic theory is based on quite restrictive assumptions, such as that the common fac
Monolithic integration of III-V semiconductors with Silicon technology has instigated a wide range of new possibilities in the semiconductor industry, such as combination of digital circuits with optical sensing and high-frequency communication. Dissimilarities in the crystal structure symmetry and large lattice mismatch between III-V’s and Si are the challenges that prevent direct epitaxial growt
Under Corona-krisen har digitaliseringen på vissa områden forcerats fram. Vi har intervjuat Stefan Larsson, docent i teknik och social förändring om digitaliseringens och plattformarnas roll, pandemiappar och hur vi kan förstå datainsamling och integritetsskyddsfrågor i relation till krisen.
The possibility of autonomous artificially intelligent systems (AAIs) has awaken a well-known worry in the scientific community as well as in popular imaginary: the possibility that beings which have gained autonomous intelligence either turn against their creators or at least make the moral and ethical superiority of creators with respect to the created questionable. The present paper argues that
This thesis consists of three self-contained papers that all relate to the understanding of equality. The first chapter investigates the effects of preschool attendance on children in Kenya and Tanzania. We use a within-household estimator and data from nationally representative surveys of school-age children's literacy and numeracy skills, which include retrospective information on preschool atte
A double burden of malnutrition occurs when individuals, household members or communities experience both undernutrition and overweight. Here, we show geospatial estimates of overweight and wasting prevalence among children under 5 years of age in 105 low- and middle-income countries (LMICs) from 2000 to 2017 and aggregate these to policy-relevant administrative units. Wasting decreased overall ac
Objective. To analyse the worldwide occurrence of sicca/Sjögren's (SS) syndrome associated with the use of immune checkpoint inhibitors (ICI) in patients with cancer. Methods. The ImmunoCancer International Registry (ICIR) is a Big Data- Sharing multidisciplinary network composed by 40 specialists in Rheumatology, Internal Medicine, Immunology and Oncology from 18 countries focused on the clinical
Women seem to use the helmet when riding a bicycle less frequently than men. Two possible explanations for this behavior are that 1) it is less appalling to them because of lack of comfort or other reasons, or 2) they use bicycles in a more cautious way than men so they feel that they do not need the helmet as much. The present paper explores these two explanations in 5, 691 cyclists that responde

Almost all countries in the world are party to the Rio Conventions. This entails a number of responsibilities, including reporting periodically on aspects of environmental health and national implementation of the convention. These reports can cover hundreds of pages, so completing reports is often a significant undertaking. Since countries can be party to numerous Multilateral Environmental Agree
A semiconductor-to-metal transition in N = 7 armchair graphene nanoribbons causes drastic changes in its electron and phonon system. By using angle-resolved photoemission spectroscopy of lithium-doped graphene nanoribbons, a quasiparticle band gap renormalization from 2.4 to 2.1 eV is observed. Reaching high doping levels (0.05 electrons per atom), it is found that the effective mass of the conduc
Invited for this month's cover is the group of Prof. Dr. Lo Gorton at Lund University, Sweden. The cover picture shows a biosensor for measuring lactose in dairy products. It consists of a gold electrode, onto which a layer of polyethyleneimine-capped gold nanoparticles is deposited. Read the full text of the article at 10.1002/cplu.201600453.
