A 1-m normal-incidence monochromator has been designed and installed on a bending-magnet beam line at the MAX storage ring in Lund. The optical properties of the beam line have been investigated via ray-tracing studies and with flux measurements of the beam line-monochromator combination. A resolution of 0.9 Å at 919.8 Å was measured in first-order diffraction with an argon hollow-cathode lamp for
Arbetet med stöd till forskningsdatahantering har utvecklats snabbt de senaste tio åren och kunskap har samlats både i publikationer och universitetsinterna rapporter. Forskarna efterfrågar infrastruktur, stöd och en universitetspolicy att luta sig emot. En analys av aggregerade behov och befintligt stöd visar att universitetet bör utveckla en samlad infrastruktur för forskningsdatalagring med möj
In a new episode of the podcast Ceteris Never Paribus, the host Maria Bach speaks to Evelina Kallträsk, David Larsson Heidenblad, Anna Nilsson Hammar and Johan Östling, all members of the Lund Centre for the History of Knowledge (LUCK). They discuss what is the history of knowledge and how its approaches might be useful for historians of economics.
Hip-related pain is an umbrella term encompassing pain from non-arthritic hip joint pathologies, such as femoroacetabular impingement syndrome, hip dysplasia, and labral tears. Exercise therapy is commonly recommended for these conditions, but the reporting completeness of these interventions is currently unclear. Purpose The aim of this systematic review was to assess the reporting completeness o
Sensitivity, specificity, and agreement between clinical and magnetic resonance imaging (MRI) gradings of the medial collateral ligament (MCL) after acute knee injury were evaluated in 362 patients. Ninety-seven per cent were injured during sports/recreation. Sensitivity and specificity of MRI for grade II or III MCL injury was 68% (95% CI 58–77%) and 90% (95% CI 86–93%), respectively. Weighted Ka
Cartilage oligomeric matrix protein (COMP) was recently implicated in the progression of breast cancer. Immunostaining of 342 prostate cancer specimens in tissue microarrays showed that COMP expression is not breast cancer-specific but also occurs in prostate cancer. The expression of COMP in prostate cancer cells correlated with a more aggressive disease with faster recurrence. Subcutaneous xenog
During development, hematopoietic cells originate from endothelium in a process known as endothelial-to-hematopoietic transition (EHT). To study human EHT, we coupled flow cytometry and single-cell transcriptional analyses of human pluripotent stem cell-derived CD34(+) cells. The resulting transcriptional hierarchy showed a continuum of endothelial and hematopoietic signatures. At the interface of

Recently, acoustophoresis has been used to fractionate white blood cells (WBC) into subpopulations, Grenvall et al. [1]. However, at a sample throughput of 8-10 μl/min the separation has limited bioanalytical application. In order to substantially increase throughput, we have redesigned and developed a new separation system that enables unmatched WBC separation performance at a volume throughput o
OBJECTIVES: Stroke is a serious complication in patients with acute type A aortic dissection (ATAAD). Previous studies investigating stroke in ATAAD patients have been limited by small cohorts and have shown diverging results. We sought to identify risk factors for stroke and to evaluate the effect of stroke on outcomes in surgical ATAAD patients. METHODS: The Nordic Consortium for Acute Type A Ao
Cancer cells display acoustic properties enabling acoustophoretic separation from white blood cells (WBCs) with 2–3 log suppression of the WBC background. However, a subset of WBCs has overlapping acoustic properties with cancer cells, which is why label-free acoustophoretic cancer cell isolation needs additional purification prior to analysis. This paper reports for the first time a proof of conc
The aim of this study was to investigate the effect of training on the in vivo tibial structural strength during the development of post-ovariectomy osteoporosis. Seventeen mature Wistar rats (215 g) were ovariectomized and randomized into two groups. The sedentary control group was kept cage confined, while 3 days postoperatively the trained group started treadmill running with high intensity for
Höksångarens Sylvia nisoria flyttning och övervintring Fåglars flyttning har fascinerat forskare under en lång tid. Från att ha varit begränsat till visuella observationer har utvecklingen tagit forskningsfältet framåt via bland annat ringmärkning, radar, satellit- och GPS-sändare. Det senaste decenniet har mycket små ljusmätande apparater gjort det möjligt att detaljerat följa även mindre fåglarTechnological advancements in the past few decades have been pushing the research field of animal migration forward rapidly. In this study light-level geolocators were used to track Swedish barred warblers Sylvia nisoria, a long-distance migrant wintering in equatorial East Africa. We obtained data on autumn migration events and on wintering sites. Ringing data from populations in Northern Europe
With the foreign political turbulence after the fall of the Berlin Wall, the world came into a change. The post-cold war environment meant that the politics of the bipolarity no longer were the case. This period leads to pressure in redefining Sweden’s foreign and security policy, resulting in an emergence of a different commitment to the countries neutrality and non-alignment. In the light of Kje
Kan spelardetektion på en plan förbättras genom att öka antalet kameror som används för detektionen? Med utvecklingen av artificiell intelligens (AI) och maskininlärning har möjligheterna inom en rad områden ökat markant, exempelvis sportteknologi. Där används AI för att automatiskt detektera spelare på en plan med hjälp av kamerabilder. I det här arbetet undersöks hur en AI-modell kan förbättra dAccurate detection of player positions is essential for sports analysis. Traditional single-camera methods generally suffer from occlusion and diminishing resolution far away. This work proposes using multi-camera Bird's Eye View (BEV) detection to overcome these issues. Synthetically generated data was used to train and test the detection model, which uses images from six cameras placed aroun
Bone Scan Index (BSI) is a quantitative measurement of tumour burden in the skeleton calculated from bone scan images. When analysed at the time of diagnosis, it has been shown to provide prognostic information on survival in men with metastatic prostate cancer (PCa). In this study, we evaluated the prognostic value of BSI during androgen deprivation therapy (ADT).
Allmänna pensionsfonderna, oftast omnämnda som AP-fonderna, är de största förvaltarna id et allmänna inkomstpensionsystemet. Fonderna har i uppdrag att investera pensionssystemets buffertkapital och eftersträva en hög långsiktig avkastning för att bidra till en hög pension för framtida generationer. För att uppfylla sitt uppdrag investerar fonderna i tusentals företag runt om i världen. Under de sThe Swedish Public Pension Funds, also known as the AP-funds, are the biggest trustees of Swedish pension payments. Their mission is to invest the buffer capital of the pension system and ensure growth that will provide pension disbursements for generations to come. To fulfil this mission investments are made in thousands of companies all over the world. During the last years the AP-funds have bee
Every year immigrants send home billions of dollars to their countries of origin. This so-called remittance flow is constantly increasing, both in scale and in importance to the economy of many developing countries. In this thesis remittance payments are discussed and analyzed in a development context. The development impact of the increasing flow of remittances is contrasted to the impacts of the
It has been previously shown that an increase in the relative value of tea increases female survival rate by enhancing their economic value. By combining contemporary district-level census data with historical data on tea production, in this paper I examine whether contemporary regional variations in gender disparities across India can be traced back to the tea production induced by the British Ea
