Prototyping Methods for Augmented Reality Interaction

The age of wearable technology devices is upon us. These devices are available in many different form factors including head-mounted displays (HMDs), smartwatches and wristbands. They enable access to information at a glance. They are intended to always be ‘‘on’’, to always be acting and to always be sensing the surrounding environment in order to offer a better interface to the real world. A tech

Association of adenomatous polyposis coli (APC) gene polymorphisms with autism spectrum disorder (ASD)

We serendipitously identified a single nucleotide polymorphism (SNP), 8636C > A (rs1804197) in the T-untranslated region of the adenomatous polyposis coli (APC) gene to be associated with autism spectrum disorder (ASD). In order to gain further evidence for the association between the APC locus and ASD, we genotyped four additional adjacent common SNPs (rs2229992, rs42427, rs459552, and rs465899)

Control-theoretic Analysis of Admission Control Mechanisms for Web Server Systems

Web sites are exposed to high rates of incoming requests. The servers may become overloaded during temporary traffic peaks when more requests arrive than the server is designed for. An admission control mechanism rejects some requests whenever the arriving traffic is too high and thereby maintains an acceptable load in the system. This paper presents how admission control mechanisms can be designe

Population viability analysis on domestic horse breeds (Equus caballus)

In this study, we performed a population viability analysis on 3 domestic horse breeds (Equus caballus) of Danish origin, namely, the Frederiksborg, the Knabstrupper, and the Jutland breeds. Because of their small population sizes, these breeds are considered endangered. The Vortex software simulation package was used for the population viability analysis. First, we investigated the future viabili

Evaluation of low-energy tailing parameters of a HPGe X-ray detector to be used in GUPIX software library for PIXE analysis

Accurate description of the response function of X-ray detectors is important for quantitative PIXE analysis. For analytical description of low-energy tailing in PIXE spectra, the GUPIX approach was used, i.e. a combination of Hypermate type functions. The low-energy tailing parameters of a low-energy high purity germanium X-ray detector in the region 1.3-9.2 keV was determined by systematic fitti

Model-Based Optimization of Tapered Free-Electron Lasers

The energy extraction efficiency is a figure of merit for a free-electron laser (FEL). It can be enhanced by the technique of undulator tapering, which enables the sustained growth of radiation power beyond the initial saturation point. In the development of a single-pass x-ray FEL, it is important to exploit the full potential of this technique and optimize the taper profile aw(z). Our approach t

Optimising Performance through Unbalanced Decompositions

When significant communication costs arise in the solution of multidimensional problems on parallel computers, optimal performance cannot always be achieved by perfectly balancing the computational load across cores. Modest sacrifices in the computational load balance may facilitate substantial overall performance improvements by achieving large savings in the costs associated with communications.

Multiplexed MALDI-MS arrays for screening of MIP solid phase extraction materials.

Technology that facilitates rapid investigation of solid phase extraction protocols using very small amounts of sorbent can save both time and money. The microfabricated ISET (Integrated Selective Enrichment Target) interfaced with MALDI mass spectrometry is able to provide an efficient, economic and generic optimization process for SPE sample preparation. The SPE is performed in a rapid and paral

Multicarrier faster-than-Nyquist transceivers: hardware architecture and performance analysis

This paper evaluates the hardware aspects of multicarrier faster-than-Nyquist (FTN) signaling transceivers. The choice of time-frequency spacing of the symbols in an FTN system for improved bandwidth efficiency is targeted towards efficient hardware implementation. This work proposes a hardware architecture for the realization of iterative decoding of FTN multicarrier modulated signals. Compatibil

Cognitive Corpus Linguistics : Five points of debate on current theory and methodology

Abstract in UndeterminedWithin cognitive linguistics, there is an increasing awareness that the study of linguistic phenomena needs to be grounded in usage. Ideally, research in cognitive linguistics should be based on authentic language use, its results should be replicable, and its claims falsifiable. Consequently, more and more studies now turn to corpora as a source of data. While corpus-based

Golgi Cell Activity During Eyeblink Conditioning in Decerebrate Ferrets.

Golgi cells have a central position in the cerebellar cortical network and are indirectly connected to Purkinje cells, which are important for the acquisition of learned responses in classical conditioning. In order to clarify the role of Golgi cells in classical conditioning, we made extracellular Golgi cell recordings during different stages of conditioning, using four different conditional stim

A facile method for expression and purification of the Alzheimer's disease-associated amyloid beta-peptide

We report the development of a high-level bacterial expression system for the Alzheimer's disease-associated amyloid beta-peptide (A beta), together with a scaleable and inexpensive purification procedure. A beta(1-40) and A beta(1-42) coding sequences together with added ATG codons were cloned directly into a Pet vector to facilitate production of Met-A beta(1-40) and Met-A beta(1-42), referred t

A performance and energy evaluation of many-light rendering algorithms

Recently, the performance of many-light algorithms, where thousands of light sources are used to compute the lighting in a scene, has improved so much that they have reached the realm of real-time rendering. In general, the algorithm that is considered “best” is the one that is the fastest in terms of time per frame. Given that power efficiency may become or already is one of the most important op

Data assignment and access scheduling exploration for multi-layer memory architectures

This paper presents an exploration framework which performs data assignment and access scheduling exploration for applications given a multilayer memory architecture. Our framework uses multiobjective criteria during exploration, such as application execution time, energy, bandwidth, and data size. In order to tackle the complexity of the exploration, it is divided into three phases; Pareto diagra

Evaluation of assimilatory sulphur metabolism in Caldicellulosiruptor saccharolyticus

Caldicellulosiruptor saccharolyticus has gained reputation as being among the best microorganisms to produce H2 due to possession of various appropriate features. The quest to develop an inexpensive cultivation medium led to determine a possible replacement of the expensive component cysteine, i.e. sulphate. C. saccharolyticus assimilated sulphate successfully in absence of a reducing agent withou

Wild-type distributions of seven oral second-line drugs against Mycobacterium tuberculosis

OBJECTIVES: To determine wild-type minimum inhibitory concentration (MIC) distributions for Mycobacterium tuberculosis, as the background data for defining susceptibility breakpoints are limited. METHODS: We determined wild-type MIC distributions of M. tuberculosis using a 96-stick replicator in Middlebrook 7H10 (7H10) medium for ethionamide (ETH), prothionamide, thiacetazone, cycloserine, rifabut
