Nuclear motion driven by the Renner-Teller effect as observed in the resonant Auger decay to the X̃2Π electronic ground state of N2O+

The nuclear dynamics in the Nt 1s→π* in nitrous oxide was studied using the high resolution resonant Auger spectroscopy and ab initio quantum chemical calculations. For probing the nuclear motion of the system in the core-excited state, the frequency detuning technique was used. The results showed changes in vibrational structure for the Auger decay spectra and a strong influence of nuclear motion

Spherical Wave Array Based Positioning for Vehicular Scenarios

Smart vehicles are emerging as a possible solution for multiple concerns in road traffic, such as mobility and safety. This work presents radio localization methods based on simultaneous direction of arrival (DOA), time-delay, and range estimation using the SAGE algorithm. The proposed methods do not rely on external sources of information, such as global navigation satellite systems (GNSS). The p

Optimized vs. Standard Automated Peritoneal Dialysis Regimens (OptiStAR) : Study protocol for a randomized controlled crossover trial

Background: It has been estimated that automated peritoneal dialysis (APD) is currently the fastest growing renal replacement therapy in the world. However, in light of the growing number of diabetic patients on peritoneal dialysis (PD), the unwanted glucose absorption during APD remains problematic. Recent results, using an extended 3-pore model of APD, indicated that large reductions in glucose

Extinction and the temporal distribution of macroevolutionary bursts

Phenotypic evolution through deep time is slower than expected from microevolutionary rates. This is the paradox of stasis. Previous models suggest stasis occurs because populations track adaptive peaks that remain relatively stable on million-year intervals, raising the equally perplexing question of why these large changes are so rare. Here, we consider the possibility that peaks can move more r

Early Onset Ataxia with Comorbid Dystonia : Clinical, Anatomical and Biological Pathway Analysis Expose Shared Pathophysiology

In degenerative adult onset ataxia (AOA), dystonic comorbidity is attributed to one disease continuum. However, in early adult onset ataxia (EOA), the prevalence and pathogenesis of dystonic comorbidity (EOAD+), are still unclear. In 80 EOA-patients, we determined the EOAD+-prevalence in association with MRI-abnormalities. Subsequently, we explored underlying biological pathways by genetic network

U-Pb baddeleyite geochronology of Precambrian mafic dyke swarms and complexes in southern Africa - regional scale extensional events and the origin of the Bushveld Complex

Popular Abstract in Swedish Diabasgångar (eng. dolerite dykes) bildas när järn- och magnesiumrika (mafiska) smältor från manteln transporteras upp genom jordskorpan och så småningom kyls av och kristalliserar i sprickor på djupet. Gångarna kan bli hundratals meter breda och kan uppträda i stort antal och bilda s.k. gångsvärmar vilka är uttryck för perioder då jordskorpan har utsatts för extensioneDolerite dykes are formed when iron- and magnesium-rich (mafic) mantle-derived magmas ascend through the lithosphere (upper part of the mantle) and crystallize as ‘hydro-fractures’ within the crust. Dykes may exist in great numbers to form dyke swarms (linear or radiating), which can be linked to time periods of continental break-up, or attempted break-up events, associated with voluminous volcani

Role of Wnt-5a in breast cancer

Popular Abstract in Swedish Bröstcancer är den vanligaste cancerformen hos västerländska kvinnor. I Sverige kommer var tionde kvinna att drabbas av bröstcancer, vilket motsvarar drygt 5000 kvinnor om året. Dödligheten i bröstcancer är 30%. Detta innebär att en tredjedel av de som drabbas kommer att dö av sin sjukdom. Det är dock inte själva tumören i bröstet som dödar eftersom denna i princip alltBreast cancer is one of the most common cancer forms in the industrialized world. Only in Sweden, nearly 6000 women are diagnosed with breast cancer each year and 1/3 of them eventually succumb to the disease. Wnts are a family of genes that have been implicated in many human tumours, so far mainly studied in colorectal cancer where activated Wnt signalling occurs in a vast majority of tumours. Wh

A Probing Feeding Strategy for Recombinant E. coli Cultivations

*Summary: The bacterium Escherichia coli is a common host organism for recombinant protein production. A problem encountered is the accumulation of the by-product acetate, which tends to reduce growth and protein production (1). Formation of acetate can be avoided by a proper substrate feeding strategy, but most strategies require considerable process knowledge to work well. The main problem is th

The transitional landscape of urbanity - territorial and visual challenges in the urban periphery of Malmö

The greater cities’ outer transitional zones are ephemeral and dynamic. With Malmö (Sweden) as an example this paper discusses how coastal and agricultural landscapes in the urban fringe can develop into something new and closer to actual needs of the inhabitants. This is done by opening up for a use of new concepts when describing these areas, for example among planners/designers and exploiters.

Uroepithelial cells are part of a mucosal cytokine network

This study compared the cytokine production of uroepithelial cell lines in response to gram-negative bacteria and inflammatory cytokines. Human kidney (A498) and bladder (J82) epithelial cell lines were stimulated with either Escherichia coli Hu734, interleukin 1α (IL-1α), or tumor necrosis factor alpha (TNF-α). Supernatant samples were removed, and the RNA was extracted from cells at 0, 2, 6, and

Quantum memory development and new slow light applications in rare-earth-ion-doped crystals

When doped into solid state transparent crystals, rare-earth ions can have optically excited states with milliseconds coherence time and up to six hours coherence time for hyperfine levels after being cooled down to liquid helium temperature. This long coherence property makes them unique as solid state material and attractive for quantum information applications.The rare-earth ions have narrow ho

Operation of the european FEL at Elettra below 190 nm : A tunable laser source for VUV spectroscopy

Thanks to an intensive technological effort in the framework of the EUFELE collaboration, the European FEL at ELETTRA was able to break the previous record for the shortest wavelength of an FEL oscillator. Novel solutions were adopted for multilayer mirrors to allow FEL operation in the wavelength region between 160 and 190 nm, which is one of the main targets of the project. The characteristics o

Tools for protective lung ventilation. The elastic pressure-volume curve and aspiration of dead space

Popular Abstract in Swedish Mekanisk ventilation kan medföra "ventilationsinducerad lungskada" (VILI), som kan öka sjuklighet och dödlighet i samband med akut lungskada (ALI). Flera ventilationssätt har föreslagits för att undvika VILI, men inte slutgiltigt utvärderats. En princip är att öka alveolär ventilation och CO2-elimination genom att minska ventilationen av de skadliga rummet, dead space. Ventilator-induced lung injury (VILI) may contribute to morbidity and mortality of acute lung injury (ALI). Lung protective ventilation (LPV), that reduces VILI, may involve low tidal volume (Vt). Particularly low Vt is possible if dead space ventilation is reduced e.g. by aspiration of dead space gas (ASPIDS). ASPIDS implies that gas rich in CO2 during expiration is aspirated through a separate c
