An algorithm is presented for the fast and accurate solution of the electrostatic equation on multi-component random checkerboards. It relies on a particular choice of integral equation, extended as to separate ill-conditioning due to singular fields in corners from ill-conditioning due to interaction of clusters of well-conducting squares at large distances. Two separate preconditioners take care
The objective of this article was to investigate the existence of horizontal inequality in access to care for six categories of elective surgery in a publicly funded system, when care is rationed through waiting lists. Administrative waiting time data on all elective surgeries (n = 4,634) performed in Östergötland, Sweden, in 2007 were linked to national registers containing variables on socioecon
Ensembles of (J,K)-regular low-density parity-check convolutional (LDPCC) codes are known to be asymptotically good, in the sense that the minimum free distance grows linearly with the constraint length. In this paper, we use a protograph-based analysis of terminated LDPCC codes to obtain an upper bound on the free distance growth rate of ensembles of periodically time-varying LDPCC codes. This bo
Developing a functional blood substitute as an alternative to donated blood for clinical use is believed to relieve present and future blood shortages, and to reduce the risks of infection and blood type mismatching. Hemoglobin vesicle (HbV) encapsulates a purified and concentrated human-derived Hb solution in a phospholipid vesicle (liposome). The in vivo safety and efficacy of HbV as a transfusi
We present ultrafast X-ray diffraction (UXRD) experiments which sensitively probe impulsively excited acoustic phonons propagating in a SrRuO3/SrTiO3 superlattice and further into the substrate. These findings are discussed together with previous UXRD results (Herzog et al. in Appl. Phys. Lett. 96, 161906, 2010; Woerner et al. in Appl. Phys. A 96, 83, 2009; v. Korff Schmising in Phys. Rev. B 78, 0
This study addresses the design of self-timed energy-minimum circuits, operating in the sub-VT domain and a generic implementation template using bundled-data circuitry and current sensing completion detection (CSCD). Furthermore, a fully decoupled latch controller was developed, which integrates with the current-sensing circuitry. Different configurations that utilise the proposed latch controlle
The phylogeny of the subfamily Xanthorioideae (Teloschistaceae) is re-analysed based on ITS, LSU and mtSSU sequences, including a new set of specimens representing 31 genera, of which five are proposed as new: Golubkovia, Igneoplaca, Langeottia, Scythioria and Verrucoplaca. Two new species, Ovealmbornia volkmarwirthii from South Africa and Gondwania sejongensis from Antarctica are described, illus
The outermost layer of the skin, the stratum corneum (SC), is a lipid-protein membrane that experiences considerable osmotic stress from a dry and cold climate. The natural moisturizing factor (NMF) comprises small and polar substances, which like osmolytes can protect living systems from osmotic stress. NMF is commonly claimed to increase the water content in the SC and thereby protect the skin f
Using inelastic proton-proton interactions at root s = 900 GeV and 7 TeV, recorded by the ATLAS detector at the LHC, measurements have been made of the correlations between forward and backward charged-particle multiplicities and, for the first time, between forward and backward charged-particle summed transverse momentum. In addition, jet-like structure in the events is studied by means of azimut
In this paper we synthesise previous sedimentological studies and new, high resolution, digital elevation models from southern Småland to investigate the evolution of a deglacial landscape. Starting approximately at the deglacial highest shoreline, there is a 20-40 km wide zone of ribbed and hummocky moraine that can be connected to the predominantly subaqueous Göteborg moraine. North of this ther
The aim of this pilot study was to evaluate the implementation of a universal school-based cognitive behavioral program whose target is to prevent depressive symptoms in adolescents. The study had a quasi-experimental design with pretest, posttest, and a 1-year follow-up and provides an illustrative calculation for the implementation costs of the intervention. Sixty-two students (aged 14) and seve
Promoting renewable energy sources (RES) has been addressed a key strategy for mitigating climate change, the governing in which has turned out a challenging and protracted task for the EU. There is often an implicit assumption that concern for climate change drives energy policy, but a closer look at the development of European RES policy indicates how EU governors have had to confront a range of
Neighborhood walkability has been associated with increased physical activity, but only a few studies have explored the association between walkability and health outcomes related to physical activity, such as type 2 diabetes. The aim of this study was to investigate the association between objectively assessed neighborhood walkability and the 4-year incidence of type 2 diabetes in a sample of 512
‘Compensated dating’’ (CD) indicates the exchange of sexual intimacy for material compensation. This article investigates CD as receiving gifts for sex, such as luxuries, rent, travel, or monetary gifts. It proceeds by describing who engages in the practice and why, while comparing Russia with its cultural and linguistic neighbors, Ukraine and Belarus. A survey, which was answered by a representat
This work deals with inverse-motion-based form finding for electroelasticity. The inverse motion problem is formulated for the electroelastic case, and the resulting equations are implemented within a finite element framework. A four-field variational approach is adopted, taking into consideration the typically incompressible behavior of the elastomer materials commonly used in electromechanical a
Occupational value with predefined items scale is an originally 26-item Swedish tool used to assess values people find in their everyday doings. The present study validated this scale on a Turkish sample and described the values that Turks perceived in their daily doings. The participants included a convenience sample of 446 adults with mean age 26 (SD = 7.3). Initial item analysis followed by pri
Poly(d,l-lactic-co-glycolic acid) (PLGA) is the most frequently used biodegradable polymer in the controlled release of encapsulated drugs. Understanding the release mechanisms, as well as which factors that affect drug release, is important in order to be able to modify drug release. Drug release from PLGA-based drug delivery systems is however complex. This review focuses on release mechanisms,
Familial clustering of prostate, breast and colorectal cancer is well established, but the familial risk of these cancers has not been determined among adoptees. The aim was to disentangle the contributions of genetic and environmental factors to the familial transmission of prostate, breast and colorectal cancer.
