We introduce new and simple algorithms for the calculation of the number of perfect matchings of complex weighted, undirected graphs with and without loops. Our compact formulas for the hafnian and loop hafnian of n × n complex matrices run in O(n32n/2) time, are embarrassingly parallelizable and, to the best of our knowledge, are the fastest exact algorithms to compute these quantities. Despite o
Over the last few decades, the African Sahel has become thefocus of many studies regarding vegetation dynamics and theirrelationships with climate and people. This is because rainfalllimits the production of biomass in the region, a resource onwhich people are directly dependent for their livelihoods. In thisstudy, we utilized a remote-sensing approach to answering thefollowing two questions: (1)
A high-resolution alpha, electron, X-ray and gamma-ray coincidence experiment was conducted at the GSI Helmholtzzentrum für Schwerionenforschung GmbH in Darmstadt, Germany. It aimed to identify and study alpha-decay chains of isotopes of element Z=115. Experimental data, including the 30 identified chains, were analyzed self-consistently with a virtually constructed spectroscopic set-up using GEAN
Spectral induced polarization (SIP) measurements have been demonstrated to correlate with important parame-ters in hydrogeological and environmental investigations. Although SIP measurements were often collected in thefrequency domain (FDIP), recent developments have demonstrated the capabilities to solve for the frequency-de-pendence of the complex conductivity through measurements collected in t
Contraction stimulates Na+,K+-ATPase and AMP-activated protein kinase(AMPK)activity in skeletal muscle. Whether AMPK activation affects Na+,K+-ATPase activity in skeletal muscle remains to be determined. Short term stimulation of rat L6 myotubes with the AMPK activator 5-aminoimidazole-4-carboxamide- 1-β-D-ribofuranoside (AICAR), activates AMPK andpromotes translocation of the Na+,K +-ATPase α1-su
Background: Incidental gallbladder cancer is a rare event, and its prognosis is largely affected by the tumour stage and treatment. The aim of this study was to analyse the management, treatment and survival of patients with incidental gallbladder cancer in a national cohort over a decade. Methods: Patients were identified through the Swedish Registry of Gallstone Surgery (GallRiks). Data were cro
Background: Preventing ischaemic stroke attracts significant focus in atrial fibrillation (AF) cases. Less is known on the association between socioeconomic factors and mortality and cardiovascular outcomes in patients with AF. Methods: Our study population included adults (n=12 283) ≥45 years diagnosed with AF at 75 primary care centres in Sweden 2001-07. Cox regression was used to calculate haza
European Spallation Source (ESS) will deliver neutrons at high flux for use in diverse neutron scattering techniques. The neutron source facility and the scientific instruments will be located in Lund, and the Data Management and Software Centre (DMSC), in Copenhagen. A number of detector prototypes are being developed at ESS together with its European in-kind partners, for example: SoNDe, Multi-G
The use of thermotolerant yeast strains is an important attribute for a cost-effective high temperature biofermentation processes. However, the availability of thermotolerant yeast strains remains a major challenge. Isolation of temperature resistant strains from extreme environments or the improvements of current strains are two major strategies known to date. We hypothesised that bacteria are po
Exoplanet interior modelling usually makes the assumption that the elemental abundances of a planet are identical to those of its host star. Host stellar abundances are good proxies of planetary abundances, but only for refractory elements. This is particularly true for terrestrial planets, as evidenced by the relative differences in bulk chemical composition between the Sun and the Earth and othe
Objective: To estimate the effect of locally tailored clinical guidelines on intrapartum care and perinatal outcomes among women with severe hypertensive disorders in pregnancy (sHDP). Methods: A pre–post study at Zanzibar's low-resource Mnazi Mmoja Hospital was conducted. All labouring women with sHDP were included at baseline (October 2014 to January 2015) and at 9–12 months after implementation
A new absorbable polymer prepared from polyhydroxybutyrate (PHB) was inserted as a pericardial patch in sheep to serve as a temporary scaffold for regeneration of pericardial tissue. Postoperative adhesions were rare or absent. The present study focuses on characterization of the regenerated surface cells. The luminal surface of the regenerated tissue was covered with a complete layer of mesotheli
Atypical gaze processing has been reported in children with autism spectrum disorders (ASD). Here we explored how infants at risk for ASD respond behaviorally to others' direct gaze. We assessed 10-month-olds with a sibling with ASD (high risk group; n = 61) and a control group (n = 18) during interaction with an adult. Eye-tracking revealed less looking at the adult in the high risk group during
The rate of convective heat transfer is often required to design and optimize food engineering processes. The temperature sensor technique is the most widely used method to measure convective heat transfer coefficients (h-values). Being able to reliably determine h-values is becoming increasingly important with the advances in sophisticated food engineering modelling using it as an empirical input
Zonulin is considered a biomarker of increased intestinal permeability, and elevated levels have been found in celiac disease. The primary aim of this study was to examine the association between serum zonulin levels and gastrointestinal (GI) symptoms, and secondarily, between zonulin levels and anthropometric and metabolic factors. The offspring (n = 363) of the participants of the Malmö Diet and
Background: Cutaneous melanoma is steadily increasing worldwide. The new AJCC 8th edition was recently launched and introduced several changes in melanoma staging, particularly for stage III. We conducted a population-based registry study with the purpose to evaluate the impact and prognostic accuracy of the new classification in Sweden. Methods: Consecutive patients diagnosed with stage III melan
The purpose of the study was to identify the bactericidal mechanism of action and time kill assay of a medicinal plant Sphaeranthus indicus Linn against some highly resistant Gram positive and Gram negative clinical pathogens. Antimicrobial action of this plant was compared with four different antibiotics using disk diffusion method. The MIC and MBC of extract was measured by broth dilution method
