Frequency-Modulated Light Scattering Interferometry Used for Assessment of Optical Properties in Turbid Media

Frequency-modulated light scattering interferometry, which employs a frequency-modulated coherent light source and examines the intensity fluctuation of the resulting scattered light using a heterodyne detection scheme, was utilized to evaluate the optical properties of liquid phantoms made of Intralipid(R) and Indian ink. Based on the diffusion theory, nonlinear fits to the power spectrum of the

Modelling and simulation of Internal Traverse Grinding: bridging meso- and macro-scale simulations

In this work, we focus on the computational bridging between the meso- and macro-scale in the context of the hybrid modelling of Internal Traverse Grinding with electro-plated cBN wheels. This grinding process satisfies the manufacturing industry demands for a high rate of material removal along with a high surface quality while minimising the number of manufacturing processes invoked. To overcome

Platelet-dependent neutrophil function is dysregulated by M protein from Streptococcus pyogenes.

Platelets are rapidly responsive sentinel cells that patrol the bloodstream and contribute to the host response to infection. Platelets have been reported to form heterotypic aggregates with leukocytes and may modulate their function. Herein we have investigated platelet-neutrophil complex formation and neutrophil function in response to distinct agonists. The endogenous platelet activator thrombi

Heat stress causes substantial labour productivity loss in Australia

Heat stress at the workplace is an occupational health hazard that reduces labour productivity(1). Assessment of productivity loss resulting from climate change has so far been based on physiological models of heat exposure(1). These models suggest productivity may decrease by 11-27% by 2080 in hot regions such as Asia and the Caribbean(2), and globally by up to 20% in hot months by 2050(3). Using

Fibrocytes and the tissue niche in lung repair

Human fibrocytes are bone marrow-derived mesenchymal progenitor cells that express a variety of markers related to leukocytes, hematopoietic stem cells and a diverse set of fibroblast phenotypes. Fibrocytes can be recruited from the circulation to the tissue where they further can differentiate and proliferate into various mesenchymal cell types depending on the tissue niche. This local tissue nic

Genome-wide search for breast cancer linkage in large Icelandic non-BRCA1/2 families

Introduction: A significant proportion of high-risk breast cancer families are not explained by mutations in known genes. Recent genome-wide searches (GWS) have not revealed any single major locus reminiscent of BRCA1 and BRCA2, indicating that still unidentified genes may explain relatively few families each or interact in a way obscure to linkage analyses. This has drawn attention to possible be

PTAS for k-tour cover poblem on the plane for moderately large values of k

Let P be a set of n points in the Euclidean plane and let O be the origin point in the plane. In the k-tour cover problem (called frequently the capacitated vehicle routing problem), the goal is to minimize the total length of tours that cover all points in P, such that each tour starts and ends in O and covers at most k points from P. The k-tour cover problem is known to be NP-hard. It is also kn

Patents and entrepreneurship: The impact of opportunity, motivation and ability

In this study, we examine individual patent holders and the fate of their inventions. A unique database consisting of over 800 private individuals who have obtained decision rights over a new technology in Sweden is used to analyse how opportunity and individual level characteristics are related to the likelihood that patented inventions are commercialised in a new or existing small firm. Our find

Grain scale experimental investigation of localised deformation in sand: a discrete particle tracking approach

Recent developments in the application of x-ray micro-tomography in laboratory geomechanics have allowed all the individual grains of sand in a test sample to be seen and identified uniquely in 3D. Combining such imaging capabilities with experiments carried out ‘‘in situ’’ within an imaging set-up has led to the possibility of directly observing the mechanisms of deformation as they happen. The c

Inclusive, prompt and non-prompt J/psi production at mid-rapidity in Pb-Pb collisions at root S-NN=2.76 TeV

The transverse momentum (p(T)) dependence of the nuclear modification factor R-AA and the centrality dependence of the average transverse momentum for inclusive J/psi have been measured with ALICE for Pb-Pb collisions at root S-NN = 2.76TeV in the e(+)e(-) decay channel at mid-rapidity (vertical bar y vertical bar < 0.8). The is significantly smaller than the one observed for pp collisions at th

Copeptin, a marker of vasopressin, in abdominal obesity, diabetes and microalbuminuria: the prospective Malmö Diet and Cancer Study cardiovascular cohort.

Background: High plasma copeptin (copeptin), the C-terminal fragment of arginine vasopressin pro-hormone, has been associated with the metabolic syndrome (MetS), diabetes mellitus (DM) development and nephropathy. Here we tested whether elevated copeptin level is associated with later development of the MetS, its individual components and microalbuminuria. Methods: We analysed copeptin at baselin

Higgs phenomenology in the stealth doublet model

We analyze a model for the Higgs sector with two scalar doublets and a Z(2) symmetry that is manifest in the Yukawa sector but broken in the potential. Thus, one of the doublets breaks the electroweak symmetry and has tree-level Yukawa couplings to fermions, whereas the other doublet has no vacuum expectation value and no tree-level couplings to fermions. Since the Z(2) parity is broken the two do

State of the Climate in 2012

For the first time in serveral years, the El Nino-Southern Oscillation did not dominate regional climate conditions around the globe. A weak La Ni a dissipated to ENSOneutral conditions by spring, and while El Nino appeared to be emerging during summer, this phase never fully developed as sea surface temperatures in the eastern conditions. Nevertheless, other large-scale climate patterns and extre

Heart or lung transplanted patients' retrospective views on information and support while waiting for transplantation.

AIMS AND OBJECTIVES: To describe the patients' retrospective experiences of the information and support they received while on the heart or lung transplant waiting list. BACKGROUND: Patients differ in the way that they cope with the time spent waiting for a heart or lung transplant. Patients must already before the transplantation be taught about a new lifestyle, risk factors, medication, food res
