Potential of multi-photon upconversion emissions for fluorescence diffuse optical imaging

The spatial resolution of fluorescence molecular imaging is a critical issue for the success of the technique in biomedical applications. One important method for increasing the imaging resolution is to utilize multi-photon emissions. In this study, we thoroughly investigate the potential of the multi-photon upconversion emissions from rare-earth-doped upconverting nanoparticles for the improvemen

Isomeric States In 208Hg And 209Tl Populated In Fragmentation Of 238U

The nuclear structure of neutron-rich N > 126 nuclei has been investigated following their production via relativistic projectile fragmentation of a E/A = 1 GeV U-238 beam on a Be target. The preliminary analysis indicates the presence of previously unreported isomeric states in the N = 128 isotones Hg-208 and Tl-209.

Transgenic systems for unequivocal identification of cardiac myocyte nuclei and analysis of cardiomyocyte cell cycle status

Even though the mammalian heart has been investigated for many years, there are still uncertainties in the fields of cardiac cell biology and regeneration with regard to exact fractions of cardiomyocytes (CMs) at different developmental stages, their plasticity after cardiac lesion and also their basal turnover rate. A main shortcoming is the accurate identification of CM and the demonstration of

Treatment with the C5a receptor antagonist ADC-1004 reduces myocardial infarction in a porcine ischemia-reperfusion model

Background: Polymorphonuclear neutrophils, stimulated by the activated complement factor C5a, have been implicated in cardiac ischemia/reperfusion injury. ADC-1004 is a competitive C5a receptor antagonist that has been shown to inhibit complement related neutrophil activation. ADC-1004 shields the neutrophils from C5a activation before they enter the reperfused area, which could be a mechanistic a

Scientific (wo)manpower - gender and the composition and earnings of PhDs in Sweden

Purpose - The purpose of this paper is to investigate to what extent male and female PhDs choose academic vs non-academic employment. Further, it analyses gender earnings differences in the academic and non-academic labour markets. Design/methodology/approach - Rich Swedish cross-sectional register data on the stock of PhDs in 2004 is used for investigating differences between male and female PhDs

High-temperature and high-concentration SCR of NO with NH3: Application in a CCS process for removal of carbon dioxide

This study investigates several commercial selective catalytic reduction (SCR) catalysts (A–E) for application in a high-temperature (approximately 525 °C) and high-concentration (5000 ppm NO) system in combination with CO2 capture. The suggested process for removing high concentrations of NOx seems plausible and autothermal operation is possible for very high NO concentrations. A key property of

Multi-agent source seeking via discrete-time extremum seeking control

Recent developments in extremum seeking theory have established a general framework for the methodology, although the specific implementations, particularly in the context of multi-agent systems, have not been demonstrated. In this work, a group of sensor-enabled vehicles is used in the context of the extremum seeking problem using both local and global optimisation algorithms to locate the extrem

Early exposure to secondhand tobacco smoke and the development of allergic diseases in 4 year old children in Malmo, Sweden

Background: Earlier studies have shown an association between secondhand tobacco smoke and allergy development in children. Furthermore, there is an increased risk of developing an allergy if the parents have an allergy. However, there are only few studies investigating the potential synergistic effect of secondhand tobacco smoke and allergic heredity on the development of an allergy. Methods: The

{1-[1-(3-Carboxypropanamido)ethyl]-1',2-bis(diphenylphosphino)ferrocene-kappa2P,P'}dichloridoplatinum(II) dichloromethane 1.25-solvate

The dinuclear title compound, [FePtCl2(C17H14P)(C23H23NO3P)]x1.25CH2Cl2, has a slightly distorted cis-PtCl2P2 square-planar geometry around the Pt atom, and the ferrocenylphosphine ligands are staggered at an angle of 29.4 (2) deg. about Pt. In the crystal structure, the complex forms centrosymmetric dimers via two strong intermolecular O—H-O bonds resulting in R22(8) rings. A weak intramolecular

A Comparison Between Unitary and Non-Unitary Precoder Design for MIMO Channels with MMSE Detection and Limited Feedback

This work studies the design of linear precoder codebooks for N-r x N-t MIMO channels with MMSE detection at the receiver. A natural split of precoder-design is unitary precoding and non-unitary precoding. Unitary precoding is only performing rotation of the data in a way beneficial for the channel. Non-unitary precoding additionally also uses power-loading to further improve the performance. Some

Understanding the migration ecology of European red admirals Vanessa atalanta using stable hydrogen isotopes

Tracking migratory movement of small animals with variable migration patterns is difficult with standard mark-recapture methods or genetic analysis. We used stable hydrogen isotope (delta D) measurements of wings from European red admirals Vanessa atalanta to study several aspects of this species' migration. In the central part of southern Europe we found large differences in delta D values betwee

Assessment of quality of life in lymphedema patients: validity and reliability of the Swedish version of the Lymphedema Quality of Life Inventory (LQOLI)

The Lymphedema Quality of Life Inventory (LQOLI) is an instrument developed for patients with different types of lymphedema. It contains physical, emotional, social, and practical dimensions and consists of 58 items, each with three sub items concerning life quality, daily life changes, and difficulties of changing and two items concerning life quality in general and in relation to lymphedema. The

Time lags in biodiversity response to farming practice

Agri-environmental schemes have been applied with the goal to mitigate negative effects of agriculture on biodiversity and ecosystem functioning. However, on evaluating the schemes the results have been variable and shown both positive and neutral effects. These variable effects can be attributed to not taking into account important factors affecting the variables at test, such as biodiversity. Th

Birth after Caesarean Section

Popular Abstract in Swedish Förlossning efter kejsarsnitt Kejsarsnitt utgör för närvarande cirka 17% av alla förlossningar i Sverige. En konsekvens av detta är att allt fler kvinnor kommer till specialistmödravården för rådgivning om vilket förlossningssätt som är säkrast vid förlossningen efter ett kejsarsnitt. Två möjligheter finns: planerad vaginal förlossning eller planerat kejsarsnitt. När maBirth after caesarean section (CS) is an issue of growing importance. As a consequence of increasing CS rates, more women having experienced a prior CS will need counselling about preferred second delivery mode. There are two choices: elective repeat caesarean section (ERCS) or trial of labour (TOL). It is well known, that a TOL ending in an emergency CS carries the largest risks for mother and ch

Approximate solution of boundary integral equations for biharmonic problems in non-smooth domains

This paper deals with approximate solutions to integral equations arising in boundary value problems for the biharmonic equation in simply connected piecewise smooth domains. The approximation method considered demonstrates excellent convergence even in the case of boundary conditions discontinuous at corner points. In an application we obtain very accurate approximations for some characteristics

Strong molecular field effects in Auger decay of the potassium 2p core-hole state in molecular KCl, KBr and KI

The K 2p photoionization and subsequent LMM Auger decay have been studied for molecular gas-phase KCl, KBr and KI. The detected manifold spectral structure of the Auger electron spectrum of KCl has been interpreted to originate from strong molecular field effects. This indicates that Auger decay on potassium side of originally very ionic molecules creates inner-shell hole states with a strong mole
