Feedbacks between climate warming, land surface aridity, and wildfire-derived aerosols represent a large source of uncertainty in future climate predictions. Here, long-term observations of aerosol optical depth, surface level aerosol loading, fire-area burned, and hydrologic simulations are used to show that regional-scale increases in aridity and resulting wildfires have significantly increased
The production of the ρ(770)0 meson has been measured at midrapidity (|y|
We study transportation networks controlled by dynamical feedback tolls. We consider a multiscale transportation network model whereby the dynamics of the traffic flows are intertwined with those of the drivers' route choices. The latter are influenced by the congestion status on the whole network as well as dynamic tolls set by the system operator. Our main result shows that a broad class of dece
The spread of new beliefs, behaviors, conventions, norms, and technologies in social and economic networks are often driven by cascading mechanisms, and so are contagion dynamics in financial networks. Global behaviors generally emerge from the interplay between the structure of the interconnection topology and the local agents' interactions. We focus on the Threshold Model (TM) of cascades first
We consider a broad class of stochastic imitation dynamics over networks, encompassing several well known learning models such as the replicator dynamics. In the considered models, players have no global information about the game structure: they only know their own current utility and the one of neighbor players contacted through pairwise interactions in a network. In response to this information
The IEEE Control Systems Society (CSS) Technical Committee on Networks and Communication Systems (TC-NCS) focuses on areas that involve the interplay among networks, communication, and systems control. The TC is organized into eight working groups, Control of Network Systems, Information Networks and Control, Networked Sensing and Sensor Networks, Optimization and Game Theoretic Methods in Network
The IEEE Control Systems Society (CSS) Technical Committee on Networks and Communication Systems (TC-NCS) focuses on areas that involve the interplay between networks, communication, and systems control. TCNCS currently has 47 members and is organized into eight working groups. These are Control of Network Systems, Networked Sensing and Sensor Networks, Optimization and Game-Theoretic Methods in N
Linkage disequilibrium in highly selfing organisms is expected to extend well beyond the scale of individual genes. The pattern of polymorphism in such species must thus be studied over a larger scale. We sequenced 14 short (0.5-1 kb) fragments from a 400-kb region surrounding the flowering time locus FRI in a sample of 20 accessions of Arabidopsis thaliana. The distribution of allele frequencies,
The aim of this study was to evaluate the effects of a novel antimuscarinic agent, Lu 25-109, a partial M1 receptor agonist, and M2/M3 receptor antagonist in human and pig detrusor to establish its affinity for muscarinic receptors in human detrusor and parotid gland and to compare the results with those obtained with oxybutynin. Effects on the detrusor were determined as regards the ability to in
Autoionization rates of the 1s2s2p4P5/2 level are computed for He-, Li I, and Be II, using the golden-rule formalism in the multiconfiguration Hartree-Fock approximation. The main objective is to clarify ambiguities concerning the metastable 4P5/2 component in He-, whose lifetimes differ significantly in various works. The present calculations reveal a much shorter lifetime, 345 mus, than predicte
Longitudinal data are presented on a boy between the ages ofthree and eight. At age three he received a diagnosis oflanguage impairment and at age six a diagnosis of high-functioning autism. Results are presented from extensive assessments at four points in time, including interviews with his mother and teachers. The results indicate that the boy s core problem was poor language comprehension, esp
1. I tested the hypothesis that the potential for non-lethal effects of predators are more important for overall performance of the fast-growing exotic signal crayfish (Pacifastacus leniusculus Dana) than for the slower growing native noble crayfish (Astacus astacus L.). I further tested if omnivorous crayfish switched to feed on less risky food sources in the presence of predators, a behaviour th
Amplification of 11q13 DNA sequences and overexpression of CCND1 are common findings in head and neck squamous cell carcinoma (HNSCC), identified in about 30% of the cases. However, little is known about initiation of the amplification and the organization of the amplicon. In order to study the structure of the amplicon in more detail and to learn more about the mechanisms involved in its initiati
Background: The purpose was to present the prevalence of all psychotic and bipolar (BP) disorders in a total general population (n=3563), which has been followed from 1947 to 1997. Materials and Methods: Best-estimate consensus DSM-IV diagnoses, supported by data from interviews, case notes, registers and key-informants, were assessed. The period prevalence from 1947 to 1997 and the lifetime preva
Background A genetic component of early-onset lung cancer has been suggested. The role of metabolic gene polymorphisms has never been studied in young lung cancer cases. Phase 1 and Phase 2 gene polymorphisms are involved in tobacco carcinogens' metabolism and therefore in lung cancer risk. Methods The effect of metabolic gene polymorphisms on lung cancer at young ages was studied by pooling data
The Dactylorhiza incarnata/maculata complex (Orchidaceae) was used as a model system to understand genetic differentiation processes in a naturally occurring polyploid complex with much of ongoing diversification and wide distribution in recently glaciated areas in northern Europe. Data were obtained for 12 hypervariable regions in the plastid DNA genome. A total of 166 haplotypes were found in a
The functional role of the GGN repeat in the human androgen receptor gene is unknown, although mutations in this region have been found in patients with inter-sex conditions. We have investigated the prevalence of GGN mutations in the androgen receptor in the Swedish population and their relation to male reproductive function. A physical examination and semen analysis was carried out in 223 men un
