Study of the elementary (K -, n) reactions to search for the K NN bound state via the 3He (K -, n) reaction at J-PARC

We have searched for the simplest kaonic nuclear state, K̄NN, using the in-flight 3He (K-, n) reaction at the J-PARC hadron experimental facility. In the semi-inclusive neutron missing-mass spectrum at θnlab=0°, an excess of yield was observed just below the K- pp mass-threshold, which cannot be explained by any elementary reactions [PTEP 2015, 061D01]. To understand the missing-mass spectrum of 3

Controlling the urge to search : Studying the informational texture of practices by exploring the missing element

This paper examines situations in which people restrict themselves in order to control their online searching and how this is negotiated. It is framed in a sociomaterial perspective taking account of the entanglement of information technology with its users and the conditions of its use. It contributes to a conceptual discussion of the sociomaterial shaping of the informational texture of issues a

Physical barriers and environmental gradients cause spatial and temporal genetic differentiation of an extensive algal bloom

Aim: To test if a phytoplankton bloom is panmictic, or whether geographical and environmental factors cause spatial and temporal genetic structure. Location: Baltic Sea. Method: During four cruises, we isolated clonal strains of the diatom Skeletonema marinoi from 9 to 10 stations along a 1132 km transect and analysed the genetic structure using eight microsatellites. Using F-statistics and Bayesi

Panel bootstrap tests of slope homogeneity

This paper proposes two bootstrap-based tests that can be used to infer whether the individual slopes in a panel regression model are homogenous. The first test is suitable when wanting to infer the null of homogeneity versus the general alternative, while the second is suitable when wanting to infer the units of the panel that can be pooled. Both approaches are shown to be asymptotically valid, a

The polysemy of ‘fallacy’—or ‘bias’, for that matter

Starting with a brief overview of current usages (Sect. 2), this paper offers some constituents of a use-based analysis of ‘fallacy’, listing 16 conditions that have, for the most part implicitly, been discussed in the literature (Sect. 3). Our thesis is that at least three related conceptions of ‘fallacy’ can be identified. The 16 conditions thus serve to “carve out” a semantic core and to distin

Global socio-technical regimes

This paper addresses the question why socio-technical transitions followsimilar trajectories in various parts of the world, even though the relevant material preconditions and institutional contexts vary greatly between different countries. It takes a critical stance on the implicit methodological nationalism in transition studies’ socio-technical regime concept and proposes an alternative ‘global

Wake analysis of drag components in gliding flight of a jackdaw (Corvus monedula) during moult

To maintain the quality of the feathers, birds regularly undergo moult. It is widely accepted that moult affects flight performance, but the specific aerodynamic consequences have received relatively little attention. Here we measured the components of aerodynamic drag from the wake behind a gliding jackdaw (Corvus monedula) at different stages of its natural wing moult. We found that span efficie

Cognitive function in stroke survivors : A 10-year follow-up study

OBJECTIVES: Post-stroke cognitive impairment (PSCI) has considerable impact on patients and society. However, long-term studies on PSCI are scarce and may be influenced by assessment methods and selection bias. We aimed to (i) assess the prevalence of long-term PSCI; (ii) compare two common cognitive assessment instruments; and (iii) compare cognitive function of long-term stroke survivors with no

The article argues that the digitally mediated and data-driven development stresses the need for socio-legal scrutiny. It focuses and briefly outline socio-legally relevant aspects of the “sharing” economy, that poses a number of conceptual issues on how we understand and regulate innovative platform based ventures.

We focus and briefly outline socio-legally relevant aspects of the “sharing” economy, that poses a number of conceptual issues on how we understand and regulate innovative platform based ventures. This also arguably underscores a number of issues relating to the role of consumer and

Clock-gating of streaming applications for energy efficient implementations on FPGAs

The paper investigates the reduction of dynamic power for streaming applications yielded by asynchronous dataflow designs by using clock gating techniques. Streaming applications constitute a very broad class of computing algorithms in areas such as signal processing, digital media coding, cryptography, video analytics, network routing and packet processing and many others. The paper introduces a

High-level synthesis of dynamic dataflow programs on heterogeneous MPSoC platforms

The growing complexity of digital signal processing applications make a compelling case the use of high-level design and synthesis methodologies for the implementation on programmable logic devices and embedded processors. Past research has shown that, for complex systems, raising the level of abstraction of design stages does not necessarily come at a penalty in terms of performance or resource r

Processes and actors: Translating Kahn processes to dataflow with firing

Dataflow programming is a paradigm for describing stream processing algorithms in a manner that naturally exposes their concurrency and makes the resulting programs readily implementable on highly parallel architectures. Dataflow programs are graph structured, with nodes representing computational kernels that process the data flowing over the edges. There are two major families of languages for t

Content-based caching in a managed runtime computing environment

A computer-implemented method of caching data in a managed runtime computing environment can include loading source data and comparing content of the source data with at least one of a plurality of cache entries. Each cache entry can include a representation of previously received source data and a transformation of the previously received source data. A transformation for the source data from a c
