BioMS is the national infrastructure for biological mass spectrometry (MS). BioMS offers access to qualified projects in proteogenomics, targeted protein quantitation, glycoproteomics, hydrogen-deuterium exchange MS, glycomics, lipidomics, and chemical proteomics. Detailed information and the project application forms can be found at www.bioms.se. BioMS is hosted by Lund University with support fr
We present a generalized theory and experimental results of the action signals induced by the absorption of two photons from two phase-modulated laser beams. In our experiment, the phases of the laser beams are modulated at the frequencies φ1 and φ2, respectively. Their collinear combination leads to the modulation of the total intensity at the frequency φ=φ2-φ1. The action signals, such as photol
Avdelningen arbetar med att skapa hållbara strukturer, processer och styrdokument inom berörda processområden vid Lunds universitet: arbetsmiljö, hälsa, lika villkor, kompetensförsörjning och kompetensutveckling. Avdelningen är ett stöd till universitetsledningen i arbetsgivarpolitiska ställningstaganden, vägleder, utbildar och genomför insatser inom avdelningens huvudområden utifrån gällande rege
The electron kinetics in nanowire-based hot-carrier solar cells is studied, where both relaxation and extraction are considered concurrently. Our kinetics is formulated in the many-particle basis of the interacting system. Detailed comparison with simplified calculations based on product states shows that this includes the Coulomb interaction both in lowest and higher orders. While relaxation rate
Avdelningen arbetar med att skapa hållbara strukturer, processer och styrdokument inom processområdet vid Lunds universitet och är ett stöd till universitetsledningen i arbetsgivarpolitiska ställningstaganden. Avdelningen vägleder, utbildar och genomför insatser inom avdelningens kompetensområde: förhandling, avtal, individuell och kollektiv arbetsrätt och omställning utifrån gällande regelverk.
Objective: The aims of the present study were to evaluate the role of the gap junction protein beta-2 gene (GJB2), encoding connexin 26 (Cx26), in children with moderate to profound prelingual nonsyndromic sensorineural hearing impairment (HI) and to investigate the carrier frequencies of the GJB2 gene mutations in a control population in Northern Finland. Methods: Mutation analysis was performed
Sektionen Globalt engagemang arbetar med att ge stöd och service till universitetets ledning, fakulteter eller motsvarande samt studenter för att stärka och utveckla Lunds universitets internationella genomslag inom forskning, utbildning, innovation och samverkan. Sektionen arbetar med att utveckla och implementera internationella strategier genom arbetet med Global Dynamic Engagement (GDE) men The Division of Global Engagement provides support and services to the university leadership, faculties, or equivalents, as well as students, to strengthen and develop Lund University's international impact in research, education, innovation, and collaboration. The division works with developing and implementing international strategies through the work with Global Dynamic Engagement (GDE), Global
A strongly coupled dipolar fluid confined in a sphere has been examined by Monte Carlo simulations using a modified distance-dependent pair interaction to emulate retardation effects. The effective dipole-dipole interaction and a property closely related to Kirkwood's g-factor have been analyzed for potentials with different distances at which the retardation effects became effective. The retardat
We present results of magnetic neutron diffraction experiments on the codoped superoxygenated La2-xSrxCuO4+y (LSCO+O) system with x=0.09. We find that the magnetic phase is long-range ordered incommensurate antiferromagnetic with a Neacuteel temperature T-N coinciding with the superconducting ordering temperature T-c=40 K. The incommensurability value is consistent with a hole doping of n(h)approx
A continuous-review two-echelon inventory system with one central warehouse and a number of nonidentical retailers is considered. The retailers face independent Poisson demand and apply standard (R, Q) policies. The retailer order quantities are fixed integer multiples of a certain batch size, representing the smallest pallet or container size transported in the system. A warehouse order may consi
We consider dynamic optimization problems for systems described by differential-algebraic equations (DAEs). Such problems are usually solved by discretizing the full DAE. We propose techniques to symbolically eliminate many of the algebraic variables in a preprocessing step before discretization. These techniques are inspired by the causalization and tearing techniques often used when solving DAE
Avdelningen förvaltar och verkar för utveckling av Lunds universitets gemensamma HR-system. Vi effektiviserar och utvecklar hantering, uppföljning och analyser av personal- och lönerelaterad data. Vi håller ihop LU-övergripande HR-administration och ansvarar för samverkan med Statens servicecenter (SSC) som är leverantör av lönetjänst till LU.
Effective freight transportation is a central part of the modern society, creating social and economic benefits. Nevertheless, the logistics industry is facing substantial sustainability challenges, where freight transports have been identified as the main environmental hazard. Scholars have previously highlighted the centrality of the purchasing process for reducing the environmental impact of th
