First Record of Megaramphoprion (Annelida; Polychaeta) in Laurentia

THE HUNTINGTON cluster (USNM 536849; Fig. 1) measures 4.1 mm in total length and is comprised of five elements of the maxillary apparatus; the first and second pair of maxillae (right and left MI and MII) and the basal plate (Bp) fitted into the bight of the right MI (for descriptive terminology for ramphoprionids, see Kielan-Jaworowska, 1966; Eriksson, 2001; Fig. 2). Both the MI are broken and la

A Novel Method to Determine Magnetic Fields in Low-density Plasma Facilitated Through Accidental Degeneracy of Quantum States in Fe9+

We propose a new method to determine magnetic fields, by using the magnetic-field-induced electric dipole transition 3p(4) 3d D-4(7/2) -> 3p(5) P-3/2 in Fe9+ ions. This ion has a high abundance in astrophysical plasma and is therefore well suited for direct measurements of even rather weak fields in, e.g., solar flares. This transition is induced by an external magnetic field and its rate is propo

A search for prompt lepton-jets in pp collisions at root s=7 TeV with the ATLAS detector

We present a search for a light (mass < 2 GeV) boson predicted by Hidden Valley supersymmetric models that decays into a final state consisting of collimated muons or electrons, denoted "lepton-jets". The analysis uses 5 fb(-1) of root s = 7 TeV proton-proton collision data recorded by the ATLAS detector at the Large Hadron Collider to search for the following signatures: single lepton-jets with a

Declarative intraprocedural flow analysis of Java source code

We have implemented intraprocedural control-flow and data-flow analysis of Java source code in a declarative manner, using reference attribute grammars augmented with circular attributes and collection attributes. Our implementation is built on top of the JastAdd Extensible Java Compiler and we have run the analyses on medium-sized Java programs. We show how the analyses can be built using sma

Temperature degradation of the gain transition in terahertz quantum cascade lasers - the role of acoustic phonon scattering

The temperature degradation in terahertz quantum cascade lasers is investigated with the focus on the role acoustic phonon scattering. A self-energy describing the electron-acoustic phonon interaction is derived and used to study the importance in transport and optical properties. We observe a strong degradation of the gain peak with temperature. Despite the very small coupling to electrons, the e

Perinatal cerebral insults alter auditory event-related potentials

Background: Auditory event-related potentials (AERPs) can be used as indices of neural information processing. Altered AERPs have been reported in children and young adults with frontal lobe infarction. Aim: To test the hypothesis that perinatal brain injury affects cortical auditory processing. Methods: We assessed AERPs at term. 6 and 12 months of age in preterm infants [n = 9. median gestationa

Pseudocoordination in Swedish with gå ‘go’ and the “surprise effect”

Pseudocoordination is a construction where two verbs or VPs appear to be conjoined by what looks like the conjunction och ‘and’. In my paper I focus on pseudocoordination with gå ‘walk, go’ as Verb 1, in particular cases where this has been claimed to give rise to a “surprise effect” (Wiklund 2005, 2008). I set out from the assumption that Verb 1 in pseudocoordination is a light verb, which, follo

Exercise capacity with special reference to type 2 diabetes

Popular Abstract in Swedish Fysisk inaktivitet och fetma är ett växande hälsoproblem i hela världen. Tre olika grupper av individer med ett brett spektrum av glukostolerans ingick i avhandlingen. Arbetskapacitet har studerats i en grupp friska fysiskt inaktiva medelålders män med normal glukostolerans i studie I och II. Hos en grupp äldre män med normal glukostolerans (NGT), nedsatt glukostoleranPhysical inactivity and obesity is a growing health problem world wide. Three different samples with a wide range of glucose tolerance were included in the thesis to represent a wider population. The exercise capacity was studied in one group of healthy sedentary middle aged men with normal glucose tolerance in study I and II. In a group of elderly men with normal glucose tolerance (NGT), impaire

Inhalable railroad particles at ground level and subterranean stations - Physical and chemical properties and relation to train traffic

The paper compares PM10 concentrations in railroad environments with EU air quality standards and characterizes particle concentrations and particle properties in relation to train traffic. The results show that PM10 concentrations in ground-level railroad environments do not exceed the EU directive 24-h limit value, while on the platforms of the two subterranean stations PM10 concentrations were

On the Reconstruction of Gapped Sinusoidal Data

The problem of estimating a spectral representation of damped sinusoidal signals from a gapped data set is of considerable interest in several applications. In this paper, we propose a filterbank approach to provide such an estimate, by first reconstructing the missing data samples assuming that the spectral content of the missing data is similar to that of the available samples, and then forming

The Aristocratic Landscape at Bergkvara Castle, Småland, Sweden

Abstract in UndeterminedCastles research has for a long period of time been concentrated to single sites: the origin of the individual castle, its different phases and dating and the castle’s place and importance in the political process. At the same time, castle studies have mainly seen the castle as a military structure. Today a broader view of the castle has emerged. The purpose of this paper i

High Resolution Structural Characterization of A beta(42) Amyloid Fibrils by Magic Angle Spinning NMR

The presence of amyloid plaques composed of amyloid beta (A beta) fibrils is a hallmark of Alzheimer's disease (AD). The A beta peptide is present as several length variants with two common alloforms consisting of 40 and 42 amino acids, denoted A beta(1-40) and A beta(1-42), respectively. While there have been numerous reports that structurally characterize fibrils of A beta(1-40), very little is

A JastAdd implementation of Oberon-0

As a part of the LDTA 2011 Tool Challenge, we implemented a compiler for the language Oberon-0 using the metacompilation tool JastAdd. In this paper, we report on this implementation, and reflect on aspects of it such as ease of use, modularity, and safety.

Correlated development of a (2 x 2) reconstruction and a charge accumulation layer on the InAs(111)-Bi surface

We have studied the formation of a Bi-induced (2 x 2) reconstruction on the InAs(111)B surface. In connection to the development of the (2 x 2) reconstruction, a two dimensional charge accumulation layer located at the bottom of the InAs conduction band appears as seen through a photoemission structure at the Fermi level. Not well ordered Bi layers do not induce a charge accumulation. The Bi-induc

Cells and polyamines do it cyclically

Cell-cycle progression is a one-way journey where the cell grows in size to be able to divide into two equally sized daughter cells. The cell cycle is divided into distinct consecutive phases defined as G(1) (first gap), S (synthesis), G(2) (second gap) and M (mitosis). A non-proliferating cell, which has retained the ability to enter the cell cycle when it receives appropriate signals, is in G(0)

Possibilities of using thermal mass in buildings to save energy, cut power consumption peaks and increase the thermal comfort

The aim of this project was to generate knowledge to enable us to take advantage of heat storage in heavy building structures with regard to as energy savings, better thermal indoor climate, and reduced peak powers. This could include buildings that can function without energy input during cold periods, buildings that give a robust indoor climate without installed cooling, and buildings with good
