The literature on trade facilitation has mostly focused on implications for trade volumes. However, recent theoretical contributions have emphasized that trade costs – such as transaction costs related to cross-border trade procedures – affect both the traded volumes of “old” goods (the intensive margin) and the range of traded goods (the extensive margin). This paper therefore tests whether trade
Introduction Bladder exstrophy is a rare congenital malformation of the bladder and is believed to be a complex disorder with genetic and environmental background. We describe a young adult female with an isolated bladder exstrophy and with an X chromosome aberration. Patients and Methods Karyotyping identified an X chromosome rearrangement that was further characterized with array comparative gen
Genome-wide association studies (GWAS) have identified 12 epithelial ovarian cancer (EOC) susceptibility alleles. The pattern of association at these loci is consistent in BRCA1 and BRCA2 mutation carriers who are at high risk of EOC. After imputation to 1000 Genomes Project data, we assessed associations of 11 million genetic variants with EOC risk from 15,437 cases unselected for family history
Stereoselective baker's yeast-catalysed bioreduction of bicyclo [2.2.2]octane-2.6-dione generates (1R, 4S, 6S)-6-hydroxy-bicyclo [2.2.2]octane-2-one (endo-alcohol) with high enantiomeric and diastereomeric excess. In contrast, whole cells and crude membrane fractions of Candida sp. have been reported to produce the unusual (I R, 4S, 6S)-diastereomer (exo-alcohol) as a major product. Previous in si
Compensation behaviour is established for the gas phase hydrodehalogenation of a range of haloarenes over a common Ni/SiO2 catalyst. Analysis of the experimental results delivers an isokinetic temperature (T-iso) at 658 +/- 2K associated with the following reactants: chlorobenzene, 4-chlorotoluene, 3-chlorophenol, 1,3,-dichlorobenzene, 4-chlorophenol, 3,5-dichlorophenol, 1,4-dichlorobenzene, bromo
The immediate environment of the transmit (TX) and receive (RX) antennas, including the antenna casings and the users holding the antennas, has a strong impact on the propagation channel and thus on wireless systems. In this paper we experimentally evaluate a method that synthetically combines double-directional measurements of the propagation channel (without the user influence) with measured ant
Atmospheric measurements show that emissions of hydrofluorocarbons (HFCs) and hydrochlorofluorocarbons are now the primary drivers of the positive growth in synthetic greenhouse gas (SGHG) radiative forcing. We infer recent SGHG emissions and examine the impact of future emissions scenarios, with a particular focus on proposals to reduce HFC use under the Montreal Protocol. If these proposals are
Delivery care in Sweden is very safe, the incidence of maternal death is 5/100 000 and perinatal death <2/100 000. The perinatal death rate among babies born at or after week 41+0 decreased from 0.17 to 0.09% (p<0.001) and obstetric anal sphincter injuries have decreased from 3.5% to 2.6%; however interventions such as induction of labour increase. A national project to improve safety for newborns
Time-dependent density functional theory (TD-DFT) calculations have been used to investigate low-energy singlet and triplet excited state potential energy surfaces (PES) of two prototype Ru-II-bistridentate complexes: [Ru-II(tpy)(2)](2+) (tpy is 2,2':6',2 ''-terpyridine) and [Ru-II(dqp)(2)](2+) (dqp is 2,6-di(quinolin-8-yl)pyridine). Solvent effects were considered using a self-consistent reaction
OBJECTIVE-To report the incidence of sight-threatening vascular lesions in type 2 diabetic subjects without retinopathy after adopting a 3-year interval screening program. RESEARCH DESIGN AND METHODS-In all, 1,691 type 2 diabetic subjects with no detectable retinopathy in two 50 degrees red-free fundus photographs were scheduled for follow-up with photography 3 years later. Age at diabetes diagnos
This paper presents a wideband CMOS power amplifier intended for cellular handset applications. The circuit exploits injection locking to achieve a power gain of 20.5dB from a single stage amplifier. The maximum output power of 29dBm, with a peak drain- and power-added-efficiency (PAE) of 66% and 64%, respectively, occurs at a center frequency of 2GHz with a 3V supply. A cross-coupled cascode topo
Analyses assessed the degrees to which personality accounts for associations between marital quality and parenting and mediates genetic contributions to these relationships. Participants included 318 male and 544 female same-sex twin pairs from the Twin and Offspring Study in Sweden. All twins completed self-report measures of marital quality and personality (anxiousness, aggression, sociability).
A novel sequential injection method for the determination of nitrite at nanomolar level in seawater samples has been developed. The pink azo compound was formed based on the Griess reaction and quantitatively adsorbed onto a Sep-Pak C18 cartridge. The enriched azo compound was rinsed with water and ethanol (28%, v/v) in turn, and then eluted with an eluent containing 26.6% (v/v) ethanol and 0.108m
A gastrostomy device is removed from the gastrostoma when no longer needed. The aim of the study was to test the hypothesis of whether it is possible for the surgeon to decide which stoma has to be closed with a gastroraphy and which to leave for a spontaneous closure within a reasonable period of time. Out of a cohort of 321 patients, who had been operated with a video-assisted gastrostomy, we in

Prefetching is a well known concept for CPUs but for GPUs it is fairly unexplored. The memory management of a GPU plays a crucial role in its performance, and cache prefetching has the potential to lower the overall latency. This thesis compares different types of prefetching methods for GPUs and remaking some CPU prefetchers to fit the GPU architecture. All these prefetchers were then put inside
In recent decades, internal and external circumstances have increased the pressure on European states and the United States to act in response to such circumstances. The return of war on the European continent, shifting trade relations, climate change and its devasting effects on society and an aging population are all putting pressure on public finances. The aim of this study is to investigate th
Animals´ omnipresence in human society makes them both close to and yet remarkably distant from humans. Human and animal lives have always been entangled, but the way we see and practice the relationships between humans and animals – as close, intertwined, or clearly separate – varies from time to time and between cultures, societies, and even situations. By putting these complex relationships in

Soil microbes drive ecosystem function and play a critical role in how ecosystems respond to global change. Research surrounding soil microbial communities has rapidly increased in recent decades, and substantial data relating to phospholipid fatty acids (PLFAs) and potential enzyme activity have been collected and analysed. However, studies have mostly been restricted to local and regional scales
