We propose and analyze a way of using pi stacking to design molecular junctions that either enhance or suppress a phononic heat current, but at the same time remain conductors for an electric current. Such functionality is highly desirable in thermoelectric energy converters, as well as in other electronic components where heat dissipation should be minimized or maximized. We suggest a molecular d

The structure, formation, and evolution of the Milky Way bulge is a matter of debate. Important diagnostics for discriminating between models of bulge formation and evolution include alpha-abundance trends with metallicity, and spatial abundance and metallicity gradients. Due to the severe optical extinction in the inner Bulge region, only a few detailed investigations of this region have been per

Spatio-temporal regulation of the balance between cell renewal and cell differentiation is of vital importance for embryonic development and adult homeostasis. Fibroblast growth factor signaling relayed from the mesenchyme to the epithelium is necessary for progenitor maintenance during organogenesis of most endoderm-derived organs, but it is still ambiguous whether the signal is exclusively mitog

The evolution of multicellular organisms represents one of approximately eight major evolutionary transitions that have occurred on earth [1-4]. The major challenge raised by this transition is to explain why single cells should join together and become mutually dependent, in a way that leads to a more complex multicellular life form that can only replicate as a whole. It has been argued that a hi

G-protein-regulated inward-rectifier potassium channel 2 (GIRK2) is reported to be expressed only within certain dopamine neurons of the substantia nigra (SN), although very limited data are available in humans. We examined the localization of GIRK2 in the SN and adjacent ventral tegmental area (VTA) of humans and mice by using either neuromelanin pigment or immunolabeling with tyrosine hydroxylas

Methanol is the second most abundant volatile organic compound in the troposphere and plays a significant role in atmospheric chemistry. While there is consensus about the dominant role of living plants as the major source and the reaction with OH as the major sink of methanol, global methanol budgets diverge considerably in terms of source/sink estimates, reflecting uncertainties in the approache

This study has explored how family members of care recipients define and sustain claims of mistreatment in old-age care. Twenty-one informants were recruited from an association of relatives of care recipients in Sweden. Using argumentation analysis, four warrants about mistreatment Were identified from the qualitative interview data: they referred to physical harm, psychological harm, social-care

This presentation is intended to illustrate various types of collisional processes relevant for free clusters probed by x-ray photoelectron spectroscopy using our own examples ranging from free-electron-metal clusters, through half-metal and semiconductor clusters to dielectrics, the latter from van-der-Waals to ionic clusters.

Inspired by state theory and in particular Nicos Poulantzas, this article claims that spatial planning should be seen neither as autonomous (subject) nor merely an expression of something else (thing), but rather grasped as a place for condensation of social relations. The notion of dialectics is used in order to grasp relations between planning and other aspects and social relations. From this, w

Abstract in UndeterminedTheoretically, there are several reasons to expect education to have a positive effect on health. Empirical research suggests that education can be an important health determinant. However, it has not yet been established whether education and health are indeed causally related, and the effects found in previous studies may be partially attributable to methodological weakne

Socioeconomic status could potentially impact on which type of rheumatic diagnosis a patient receives. We determined whether different socioeconomic status is a risk factor for being diagnosed with spondyloarthritis (SpA) or chronic pain. In a nested case-control study, we identified two sets of adult cases diagnosed with (i) SpA (n = 1,194) and (ii) chronic pain (n = 3,730) during 2010-2012 in Sk

Measurement noise can generate undesired control activity resulting in wear of actuators and reduced performance. The effects of measurement noise can be alleviated by filtering the measurement signal.The design of the filter is then a trade-off; heavy filtering reduces the undesired control activity but performance is degraded. In this paper we discuss the trade-offs for PID control. Based on the

It is commonly believed that higher order smoothness should be modeled using higher order interactions. For example, 2nd order derivatives for deformable (active) contours are represented by triple cliques. Similarly, the 2nd order regularization methods in stereo predominantly use MRF models with scalar (1D) disparity labels and triple clique interactions. In this paper we advocate a largely over

Pneumococcal surface protein C (PspC) is a major virulence factor of Streptococcus pneumoniae and interferes with complement activity by binding complement factor H (fH). In this study, protection against experimental sepsis caused by pneumococci carrying different PspC variants was evaluated by immunisation with the fH-binding fragment of PspC. The mechanisms of protection mediated by antibodies

Early-life inorganic arsenic exposure influences not only child health and development but also health in later life. The adverse effects of arsenic may be mediated by epigenetic mechanisms, as there are indications that arsenic causes altered DNA methylation of cancer-related genes. The objective was to assess effects of arsenic on genome-wide DNA methylation in newborns. We studied 127 mothers a

Anxiety is an emotion, which stimulates sympathetic nervous outflow potentially facilitating vasovagal reflex syncope (VVS) but reports on anxiety levels in patients with VVS are sparse.

Specific motor symptoms of Parkinson's disease (PD) can be treated effectively with direct electrical stimulation of deep nuclei in the brain. However, this is an invasive procedure, and the fraction of eligible patients is rather low according to currently used criteria. Spinal cord stimulation (SCS), a minimally invasive method, has more recently been proposed as a therapeutic approach to allevi

This study investigates definite articles in specific and generic subject nominals in Italian spoken by adult simultaneous bilinguals (2L1ers) and second language learners (L2ers). The study focuses on plural and mass DPs, in which German and Italian differ. The aims are to (i) compare acquisition outcomes between the weaker and the stronger language in 2L1 acquisition, (ii) see in a comparison wi

Microtubule nucleation requires the γ-tubulin ring complex, and during the M phase (mitosis) this complex accumulates at the centrosome to support mitotic spindle formation. The post-translational modification of γ-tubulin through ubiquitination is vital for regulating microtubule nucleation and centrosome duplication. Blocking the BRCA1/BARD1-dependent ubiquitination of γ-tubulin causes centrosom
