Chovanec, JohannaHeilo, OlofHeilo, Olof2021This chapter strikes a bridge from current-day imaginations to pre-modern concepts of empire. It shows how, on the one hand, modern visions of empire are echoing political and religious notions of an all-encompassing rule that go back to Antiquity. On the other hand, it stresses how such modern conceptualizations tend to fall short on understanding diversity in a world where state penetration and identity articulation were dependent on various intermediaries. This paper shows how pre-modern Habsburg and Ottoman approaches to unity and diversity came into conflict with modernisation projects that tried to reduce the number of intermediaries and thus created a need for narratives of power that connected rulers to subjects in a new way. The emergence of articulate, interconnected and self-aware classes in both empires that tied hopes for political progress to narratives of nation created both challenges and possibilities for the two dynasties. This created the premise for media discourses where the empire was envisioned as a nation of many peoples.https://lup.lub.lu.se/record/9e419644-bf17-40ee-9387-cee40a7cdb70http://dx.doi.org/10.1007/978-3-030-55199-5_2ISBN: 9783030551995ISBN: 9783030551988ISBN: 9783030552015scopus:85130612837engModernity, Memory and Identity in South-East Europe; pp 37-54 (2021)ISSN: 2523-7985ISSN: 2523-7993HistoryMaking Sense in a World that is Falling Apart : Imperial Narratives of State, Diversity and Modernitycontributiontobookanthology/chapterinfo:eu-repo/semantics/bookParttextContinuous hand-eye calibration using 3D points

Grossmann, BjarneKrüger, Volker2017The recent development of calibration algorithms has been driven into two major directions: (1) an increasing accuracy of mathematical approaches and (2) an increasing flexibility in usage by reducing the dependency on calibration objects. These two trends, however, seem to be contradictory since the overall accuracy is directly related to the accuracy of the pose estimation of the calibration object and therefore demanding large objects, while an increased flexibility leads to smaller objects or noisier estimation methods. The method presented in this paper aims to resolves this problem in two steps: First, we derive a simple closed-form solution with a shifted focus towards the equation of translation that only solves for the necessary hand-eye transformation. We show that it is superior in accuracy and robustness compared to traditional approaches. Second, we decrease the dependency on the calibration object to a single 3D-point by using a similar formulation based on the equation of translation which is much less affected by the estimation error of the calibration object's orientation. Moreover, it makes the estimation of the orientation obsolete while taking advantage of the higher accuracy and robustness from the first solution, resulting in a versatile method for continuous hand-eye calibration.https://lup.lub.lu.se/record/09d903dc-880d-4efc-8c6f-0be83498335fhttp://dx.doi.org/10.1109/indin.2017.8104791ISBN: 978-1-5386-0837-1ISBN: 978-1-5386-0838-8scopus:85041226045engComputer Vision and Robotics (Autonomous Systems)continuous hand-eye calibrationcalibration algorithmsnoisier estimation methodsnecessary hand-eye transformationcalibration object pose estimationsingle 3D-pointcalibration object orientation error estimationContinuous hand-eye calibration using 3D pointscontributiontobookanthology/conferenceinfo:eu-repo/semantics/conferencePapertextAgreement between test procedures for the single-leg hop for distance and the single-leg mini squat as measures of lower extremity function

Ageberg, EvaCronström, Anna2018-08-22Background: Different test procedures are often used within performance-based measures, causing uncertainty as to whether results can be compared between studies. Thus, the aim of this study was to assess agreement between different test procedures for the single-leg hop for distance (SLHD) and the single-leg mini squat (SLMS), respectively, two commonly used tasks for assessing deficiency in lower extremity muscle function.Methods: Twenty-three participants (20-42 years) with lower extremity injury performed the SLHD with arms free and with arms behind back, and the Limb Symmetry Index (LSI; injured leg divided by uninjured and multiplied by 100) was calculated. Another group of 28 participants (mean 18-38 years) performed five SLMSs at a pre-defined speed and maximum number of SLMSs during 30 seconds, and were visually observed and scored as either having a knee-over-foot or a knee-medial-to-foot position (KMFP).Results: No systematic difference between test procedures for the LSI of the SLHD was noted (p=0.736), Cohen's kappa = 0.42. The Bland & Altman plot showed wide limits of agreement between test procedures, with particularly poor agreement for participants with abnormal LSI (<90%). Ten participants were scored as having a KMFP during five SLMSs at a predefined speed, while five had a KMFP during maximum number of SLMSs during 30 seconds (p=0.063, Cohen's kappa = 0.56).Conclusions: The moderate agreement between the two test procedures for the SLHD and the SLMS, respectively, indicate that results from these different test procedures should not be compared across studies. SLHD with arms behind back, and five SLMSs at a pre-defined speed, respectively, were the most sensitive procedures to detect individuals with poor functional performance.https://lup.lub.lu.se/record/6e2a0415-36b4-4274-8c27-7590f610b3eehttp://dx.doi.org/10.1186/s13102-018-0104-6scopus:85065608679pmid:30167308engBMC Sports Science, Medicine and Rehabilitation; 10(15), no 15 (2018)ISSN: 2052-1847Sport and Fitness SciencesPhysiotherapyAgreement between test procedures for the single-leg hop for distance and the single-leg mini squat as measures of lower extremity functioncontributiontojournal/articleinfo:eu-repo/semantics/articletextGWAS of bone size yields twelve loci that also affect height, BMD, osteoarthritis or fractures

In a GWA study of DXA bone area of the hip and lumbar spine (N ≥ 28,954), we find thirteen independent association signals at twelve loci that replicate in samples of European and East Asian descent (N = 13,608 – 21,277). Eight DXA area loci associate with osteoarthritis, including rs143384 in GDF5 and a missense variant in COL11A1 (rs3753841). The strongest DXA area association is with rs11614913[T] in the microRNA MIR196A2 gene that associates with lumbar spine area (P = 2.3 × 10
−42
, β = −0.090) and confers risk of hip fracture (P = 1.0 × 10
−8
, OR = 1.11). We demonstrate that the risk allele is less efficient in repressing miR-196a-5p target genes. We also show that the DXA area measure contributes to the risk of hip fracture independent of bone density.https://lup.lub.lu.se/record/1dcd3cc7-b010-4fc7-b450-49acaa552500http://dx.doi.org/10.1038/s41467-019-09860-0pmid:31053729scopus:85065194502engNature Communications; 10(1), no 2054 (2019)ISSN: 2041-1723Medical GeneticsOrthopedicsGWAS of bone size yields twelve loci that also affect height, BMD, osteoarthritis or fracturescontributiontojournal/articleinfo:eu-repo/semantics/articletextBorders and Boundaries?

Bredberg, AndersSchmitz, Birger2019We argue that the human evolutionary heritage with frequent adaptations through geological time to environmental change has affected a trade-off between offspring variability and cancer resistance, and thus favored cancer-prone individuals. We turn the attention to a factor setting the highly cancer-resistant naked mole rat apart from most other mammals: it has remained phenotypically largely unchanged since 30-50 million years ago. Research focusing on DNA stability mechanisms in ‘living fossil’ animals may help us find tools for cancer prevention and treatment.https://lup.lub.lu.se/record/b190fee2-b8cb-470b-8265-2da851276a58http://dx.doi.org/10.1002/cam4.2011pmid:30790458scopus:85065078389engCancer Medicine; 8(4), pp 1652-1654 (2019)ISSN: 2045-7634Medical Geneticscancer resistanceCretaceous-Paleogene boundaryHeterocephalus glaberhuman cancer excesshuman mutation ratenaked mole ratPeto's paradoxrapid human evolutionHuman cancer, the naked mole rat and faunal turnoverscontributiontojournal/articleinfo:eu-repo/semantics/articletextCircadian onset and prognosis of myocardial infarction with non-obstructive coronary arteries (MINOCA)

Nordenskjöld, Anna M.Eggers, Kai M.Jernberg, TomasMohammad, Moman A.Erlinge, DavidLindahl, Bertil2019-04-25Background Many acute cardiovascular events such as myocardial infarction (MI) follow circadian rhythms. Myocardial infarction with non-obstructive coronary arteries (MINOCA) is a newly noticed entity with limited data on onset pattern and its impact on prognosis. Material and methods In this observational study of Swedish MINOCA patients registered in the SWEDEHEART registry between 2003–2013 and followed until December 2013 we identified 9,092 unique patients with MINOCA out of 199,163 MI admissions in total. Incidence rate ratios (IRR) were calculated for whole hours, parts of the day, weekdays, months, seasons and major holidays. Results The mean age was 65.5 years, 62.0% were women and 16.6% presented with STEMI. The risk for MINOCA proved to be most common in the morning (IRR = 1.70, 95% CI [1.63–1.84]) with a peak at 08.00 AM (IRR = 2.25, 95% CI [1.96–2.59]) and on Mondays (IRR = 1.28, 95% CI [1.18–1.38]). No altered risk was detected during the different seasons, the Christmas and New Year holidays or the Swedish Midsummer festivities. There was no association between time of onset of MINOCA and short- or long-term prognosis. Conclusion The onset of MINOCA shows a circadian and circaseptan variation with increased risk at early mornings and Mondays, similar to previous studies on all MI, suggesting stress related triggering. However, during holidays were traditional MI increase, we did not see any increase for MINOCA. No association was detected between time of onset and prognosis, indicating that the underlying pathological mechanisms of MINOCA and the quality of care are similar at different times of onset but triggering mechanism may be more active early mornings and Mondays.https://lup.lub.lu.se/record/eeee144d-ca09-4cca-bbe1-303cf580e6bfhttp://dx.doi.org/10.1371/journal.pone.0216073pmid:31022242scopus:85064929033engPLoS ONE; 14(4), no e0216073 (2019)ISSN: 1932-6203Cardiac and Cardiovascular SystemsCircadian onset and prognosis of myocardial infarction with non-obstructive coronary arteries (MINOCA)contributiontojournal/articleinfo:eu-repo/semantics/articletextRepeated disturbances affect functional but not compositional resistance and resilience in an aquatic bacterioplankton community

Sjöstedt, JohannaLangenheder, SilkeKritzberg, EmmaKarlsson, Christofer M GLindström, Eva S2018-05-07Disturbances are believed to be one of the main factors influencing variations in community diversity and functioning. Here we investigated if exposure to a pH press disturbance affected the composition and functional performance of a bacterial community and its resistance, recovery and resilience to a second press disturbance (salt addition). Lake bacterial assemblages were initially exposed to reduced pH in six mesocosms whereas another six mesocosms were kept as reference. Seven days after the pH disturbance, three tanks from each treatment were exposed to a salt disturbance. Both bacterial production and enzyme activity were negatively affected by the salt treatment, regardless if the communities had been subject to a previous disturbance or not. However, cell-specific enzyme activity had a higher resistance in communities pre-exposed to the pH disturbance compared to the reference treatment. In contrast, for cell-specific bacterial production resistance was not affected, but recovery was faster in the communities that had previously been exposed to the pH disturbance. Over time, bacterial community composition diverged among treatments, in response to both pH and salinity. The difference in functional recovery, resilience and resistance may depend on differences in community composition caused by the pH disturbance, niche breadth or acquired stress resistance.https://lup.lub.lu.se/record/f389fbe5-f4e5-4430-bee4-df2fdd71d2d3http://dx.doi.org/10.1111/1758-2229.12656scopus:85050464256pmid:29733107engEnvironmental microbiology reports; 10(4), pp 493-500 (2018)ISSN: 1758-2229EcologyBacteria/classificationBacterial Physiological PhenomenaCarbon/metabolismCellulose 1,4-beta-Cellobiosidase/metabolismHydrogen-Ion ConcentrationLakes/microbiologyPlankton/classificationRNA, Ribosomal, 16S/geneticsSalinityStress, Physiological/physiologyWater Microbiologybeta-Glucosidase/metabolismRepeated disturbances affect functional but not compositional resistance and resilience in an aquatic bacterioplankton communitycontributiontojournal/articleinfo:eu-repo/semantics/articletextHigh Electron Mobility and Insights into Temperature-Dependent Scattering Mechanisms in InAsSb Nanowires

Boland, Jessica LAmaduzzi, FrancescaSterzl, SabrinaPotts, HeidiHerz, Laura MFontcuberta I Morral, AnnaJohnston, Michael B2018-06-13InAsSb nanowires are promising elements for thermoelectric devices, infrared photodetectors, high-speed transistors, as well as thermophotovoltaic cells. By changing the Sb alloy fraction the mid-infrared bandgap energy and thermal conductivity may be tuned for specific device applications. Using both terahertz and Raman noncontact probes, we show that Sb alloying increases the electron mobility in the nanowires by over a factor of 3 from InAs to InAs0.65Sb0.35. We also extract the temperature-dependent electron mobility via both terahertz and Raman spectroscopy, and we report the highest electron mobilities for InAs0.65Sb0.35 nanowires to date, exceeding 16,000 cm2 V-1 s-1 at 10 K.https://lup.lub.lu.se/record/35932409-7864-4eb1-857e-3adf89a0041ehttp://dx.doi.org/10.1021/acs.nanolett.8b00842scopus:85046683699pmid:29717874engNano Letters; 18(6), pp 3703-3710 (2018)ISSN: 1530-6992High Electron Mobility and Insights into Temperature-Dependent Scattering Mechanisms in InAsSb Nanowirescontributiontojournal/articleinfo:eu-repo/semantics/articletext
