We present a new, scalable alternative to the structured singular value, which we call v, provide a convex upper bound, study their properties and compare them to l1 robust control. The analysis relies on a novel result on the relationship between robust control of dynamical systems and non-negative constant matrices.
We developed a process for enzyme-linked immunosorbent assay on a glass microchip via the use of a thin-layered microfluidic channel. This channel possesses a high aspect ratio (width/depth ∼200) and has an antibody layer immobilized directly on the channel surface. A depth of several microns and an excessive width and length (mm scale) of the channel provide a large-volume capacity (102 nL) and m
Vid utgrävningar på Løgstrup SØ II, Fiskbӕk s:n, Nørlyng h:d (Jylland) påträffades under 2008 års utgrävningssäsong flertalet tydliga spår av bronshantverk i form av deglar, gjutformar, råmaterial m.m. Bland fynden fanns tre stycken metalltenar vilka förmodades vara råmaterial (tenn) för bronsgjuteri. För att bekräfta vad dessa tenar består av har Keramiska Forskningslaboratoriet, Lunds Universite
Short-wavelength synchrotron radiation excitation has been an indispensable tool in the studies of the properties of wide gap materials using time-resolved low-temperature luminescence spectroscopy. In recent years, several setups for such investigations have been launched at MAX IV Laboratory and Photon Science at DESY. Two permanently stationed time-resolved luminescence setups at FinEstBeAMS an
In statistics, samples are drawn from a population in a data-generating process (DGP). Standard errors measure the uncertainty in estimates of population parameters. In science, evidence is generated to test hypotheses in an evidence-generating process (EGP). We claim that EGP variation across researchers adds uncertainty—nonstandard errors (NSEs). We study NSEs by letting 164 teams test the same
Mycoplasma pneumoniae (M. pneumoniae) is a common cause of community acquired pneumonia and although most cases are mild, complications sometimes occur. Cold agglutinin hemolysis is a known complication of M. pneumoniae infection, and usually presents as a mild and transient hemolysis. Here we present a case of infection with M. pneumoniae in a 64-year-old male that caused life threatening hemolys
The use of charge balance functions in heavy-ion collision studies was initially proposed as a probe of delayed hadronization and two-stage quark production in these collisions. It later emerged that general balance functions can also serve as a probe of the diffusivity of light quarks as well as the evolution of the systems formed in heavy-ion collisions. In this work, we reexamine the formulatio
The aim of the current study was to examine the prevalence of ideal cardiovascular health (iCVH) in the general Swedish middle-aged population. To address this aim, we utilised data from the Swedish CArdioPulmonary bioImage Study (SCAPIS) which is a large Swedish population-based study (N=30,154) that combined comprehensive state-of-the-art imaging technology with clinical examinations and include
According to Lefebvre, modern capitalism has led to the commodification of urban life. Even though commodification has taken multiple distinct forms across the urban fabric, it could be argued that no urban feature is more representative of the proliferation of exchange values than shopping malls. Despite being privately owned and managed, commercialised and highly securitised, shopping malls have
Introduction: Our objective was determining the optimal combinations of cerebrospinal fluid (CSF) biomarkers for predicting disease progression in Alzheimer's disease (AD) and other neurodegenerative diseases. Methods: We included 1,983 participants from three different cohorts with longitudinal cognitive and clinical data, and baseline CSF levels of Aβ42, Aβ40, phosphorylated tau at threonine-181
Arctic-boreal landscapes are experiencing profound warming, along with changes in ecosystem moisture status and disturbance from fire. This region is of global importance in terms of carbon feedbacks to climate, yet the sign (sink or source) and magnitude of the Arctic-boreal carbon budget within recent years remains highly uncertain. Here, we provide new estimates of recent (2003–2015) vegetation
This thesis is composed of five papers, which all attempt to optimise calculations of scattering amplitudes in high-energy-physics collisions. These scattering amplitudes are a key part of theoretical predictions for particle-physics experiments like the Large Hadron Collider at CERN. The first four papers are the main topic of the thesis, and describe a novel method called chirality flow. Chirali
När LTH hade hunnit ungefär till halvtid, det vill säga för 25 år sedan, uppkom en liten centrumbildning för rehabiliteringsteknik med akronymen ”Certec”. Nu år 2011 ingår Certec i Institutionen för Designvetenskaper med sitt forskarutbildningsämne ”rehabiliteringsteknik” som en av institutionens sju forskningsinriktningar.Namnet ”Certec” behövs alltså inte längre, men det finns kvar som vårt posi
