The number of triangulations of a planar n point set S is known to be cn, where the base c lies between 2.43 and 30. Similarly, the number of crossing-free spanning trees on S is known to be dn, where the base d lies between 6.75 and 141.07. The fastest known algorithm for counting triangulations of S runs in 2(1+o(1))nlog n time while that for counting crossing-free spanning trees runs in O (7.12
The study of solvation in pressurized systems requires in situ analysis. An optimal spectroscopic technique for such studies would enable the detection of any compound and have resolution enough to differentiate different compounds within a multicomponent mixture. Here we show for the first time that we can follow dissolution kinetics of a model compound, d-limonene, in supercritical carbon dioxid
The purpose of the present study was to investigate the intercomprehension processes of multilingual Swedish L1 speakers while reading and decoding text in Italian, an unknown language. The three Swedish L1 participants in the present case study had English as L2 and respectively French, Spanish and German as L3. The participants read two texts in Italian, a language unknown to them, and using thi
Laser spectroscopy has a multitude of applications of importance to human and ecosystem well-being, such as in the environmental, ecological, agricultural and food safety areas. Recent work, mostly from SCNU, will be reviewed.
Laser based spectroscopic techniques can be used in the detection and therapy of many human diseases. Examples will be given from a variety of clinical areas, such as oncology, orthopedics and pediatrics, and also from the field of food safety and antibiotic control.
NanoMAX is a hard x-ray nanoimaging beamline at the new Swedish synchrotron radiation source MAX IV that became operational in 2016. Being a beamline dedicated to x-ray nanoimaging in both 2D and 3D, NanoMAX is the first to take full advantage of MAX IVs exceptional low emittance and resulting coherent properties. We present results from the first experiments at NanoMAX that took place in December
Based on linked employer-employee panel data on all Swedish inventors, this paper analyses how wages affect inventors' job mobility. It is commonly assumed that higher wages reduce mobility because they reduce the value of outside opportunities. We argue that higher wages also send performance signals to potential employers, who raise their wage offers in response. By disentangling the effects of
This paper addresses how to identify attack relations on the basis of lay arguers’ acceptability-judgments for natural language arguments. We characterize argument-based reasoning by three Bayesian network models (coherent, decisive, and positional). Each model yields a different attack relation-estimate. Subsequently, we analyze to which extent estimates are consistent with, and so could potentia
Organtransplantation har under de senaste decennierna utvecklats från att vara en experimentell behandling till att bli huvudbehandling för en rad sjukdomar. Förbättringar i immundämpande behandlingar anses generellt vara en av huvudorsakerna till denna utveckling, som också har medfört bättre utfall i form av överlevnad och livskvalitet. Under samma tidsperiod har kostnaden per transplantation mi
ABSTRACT. Serum concentrations of creatinine and of the three low molecular weight (LMW) proteins cystatin C, factor D of the complement system and β2‐microglobulin were measured in 135 consecutive patients, whose glomerular filtration rates (GFR) were determined by Cr‐EDTA. In the total patient series, the reciprocals of S‐creatinine and S‐cystatin C were numerically and, in males, significantly
ALTHOUGH the total incidence of cerebral hemorrhage is high, comparatively few reports concerning the familial occurrence of this disease have been published.1,2 In 1935 Arnason described 10 families with a high incidence of cerebral hemorrhage and concluded that a hereditary form of the disease was present in these families.3 Further clinicopathological investigations of the disease revealed an a
Denna rapport redovisar en förstudie till SNS fleråriga forskningsprojekt som undersöker hur värdet av nya läkemedel kan bedömas ur ett brett samhällsperspektiv. En slutsats av förstudien är att det finns goda möjligheter att få bättre svar på många av de policyfrågor som ställs i läkemedelspolitiken, t ex om förskrivning och offentlig subventionering av nya läkemedel. De omfattande svenska patien
The goal of this work is to explore ways of generating state trajectories for dynamical systems subject to computational constraints, obstacles and priority assignment. The algorithms are developed for a miniature unmanned aerial vehicle (UAV) in a modular fashion and include (1) a genetic algorithm (GA) for solving the traveling salesman problem (TSP) with respect to priorities and obstacle avoid
A plethora of studies have shown that the physicochemical properties of oat β-glucan determine its health benefits. However, the impact of the passage through the gastrointestinal tract on the conformational and structural characteristics is not fully understood. The present study aims to elucidate the structure and conformation of gently extracted oat β-glucan before and after in vitro gastric an
Myndigheten för samhällsskydd och beredskap (MSB) har efterfrågat synpunkter av Lunds Tekniska Högskola på det rapporteringsverktyg för risk- och sårbarhetsanalyser som MSB utvecklar. Verktyget är tänkt att underlätta förmedling och insamling av information som framkommer genom de risk- och sårbarhetsanalyser som kommuner och landsting samt myndigheter upprättar enligt föreskrifterna MSBFS 2010:6
This study contributes to the establishment of frequency recommendations for use in coda wave interferometry structural health monitoring (SHM) systems for concrete structures. To this end, codas with widely different central frequencies were used to detect boreholes with different diameters in a large concrete floor slab, and to track increasing damage in a small concrete beam subjected to bendin
Diffuse ultrasonic wave measurements used in structural health monitoring applications can detect damage in concrete. However, the accuracy is very susceptible to environmental variations. In this study, a large concrete floor slab was monitored using diffuse wave fields that were generated by continuous-wave transmissions between ultrasonic transducers. The slab was monitored for several weeks wh
