In this paper we argue that the emergence of the dominant model of university organization, which is characterized by a large agglomeration of many (often loosely affiliated) small research groups, might have an economic explanation that relates to the features of the scientific production process. In particular, we argue that there are decreasing returns to scale on the level of the individual re
BACKGROUND AND PURPOSE: The breast cancer susceptibility genes BRCA1 and BRCA2 interact with Rad51, one of the central components in the homologous recombination repair pathway. This study evaluates the prognostic and predictive role of BRCA1, BRCA2 and Rad51, individually and as a complex, in breast cancer.MATERIALS AND METHODS: Expression of BRCA1, BRCA2 and Rad51 was investigated using immunohi
Money is central to capitalism and its sustainability crises. This article argues that it is not money itself, but its internal design and governance – how it is created, distributed, and governed – that drives inequality, ecological degradation, and unsustainable growth. Yet, money’s architecture is not fixed; it can be reimagined to foster fairer, greener economies.Approaching money as a socio-t
We show that algebraic proofs are hard to find: Given an unsatisfiable CNF formula F, it is NP-hard to find a refutation of F in the Nullstellensatz, Polynomial Calculus, or Sherali-Adams proof systems in time polynomial in the size of the shortest such refutation. Our work extends, and gives a simplified proof of, the recent breakthrough of Atserias and Müller (JACM 2020) that established an anal
A new and freely available model-based PID design tool for Matlab is introduced. It can be used to solve Maximal Integral Gain Optimization (MIGO) and (load) Integral Absolute Error (IAE) problems. Robustness is ensured through H-inf constraints on the closed-loop transfer functions. A Youla parameter (Q design) method for comparison with the optimal linear time-invariant (LTI) controller for the
The UN Sustainable Development Goal (SDG) 7 states that access to affordable, reliable, sustainable, and modern energy should be provided for all by 2030. The effects on socioeconomic development by access to safe, affordable, and clean electricity stands out as educational benefits, income improvement, and health progress. However, the electrification rate has been slow for sub-Saharan Africa and
Background: Familial confounding is confounding due to genetics or environmental exposures shared by family members. We aimed to study whether familial confounding explains the association between body mass index (BMI) and severe hip osteoarthritis (OA). Methods: We linked data from the Norwegian Arthroplasty Registry with the Norwegian Twin Registry on the National ID-number in 2014, generating a
The problem of estimating receiver or sender node positions from measured receiver-sender distances is a key issue in different applications such as microphone array calibration, radio antenna array calibration, mapping and positioning using UWB or using round-trip-time measurements between mobile phones and WiFi-units. In this paper we address the problem of optimally estimating a receiver positi

Andrea Stuart är gynekolog med fokus på benign gynekologisk kirurgi och utveckling av minimalinvasiva metoder. Hon leder flera stora kliniska studier, bland annat den internationella RCT:n VANOLAH, som jämför vNOTES med vaginal kirurgi och laparoskopi för hysterektomi, samt den multinationella ADNOLA-studien där laparoskopi ställs mot vNOTES vid äggstockskirurgi för att optimera metodval och förbäAndrea Stuart is a gynecologist specializing in benign gynecological surgery, focusing on developing and comparing minimally invasive techniques. She leads a large international RCT comparing vNOTES with vaginal surgery and laparoscopy to determine which hysterectomy method offers the best outcomes and lowest complication rates. She also heads a multinational RCT comparing laparoscopy with vNOTES
In this letter we derive fundamental limitations on the levels of H {2} and H {\infty {}} performance that can be achieved when controlling lossless systems. The results are applied to the swing equation power system model, where it is shown that the fundamental limit on the H {2} norm scales with the inverse of the harmonic mean of the inertias in the system. This indicates that power systems may
