The TESS-HERMES survey data release 1 : High-resolution spectroscopy of the TESS southern continuous viewing zone

The Transiting Exoplanet Survey Satellite (TESS) will provide high-precision time series photometry for millions of stars with at least a half-hour cadence. Of particular interest are the circular regions of 12° radius centred around the ecliptic poles that will be observed continuously for a full year. Spectroscopic stellar parameters are desirable to characterize and select suitable targets for

Approximate integrals of motion

We determine approximate numerical integrals of motion of 2D symmetric Hamiltonian systems. We detail for a few gravitational potentials the conditions under which quasi-integrals are obtained as polynomial series. We show that each of these potentials has a wide range of regular orbits that are accurately modelled with a unique approximate integral of motion.

Characterising the temporal evolution of fixation in human post mortem brain via linear relaxometry modelling – a marker of cross-linking?

MRI-based biophysical models are typically validated by comparison to ex-vivo histology of fixed tissue. The fixation process itself and the accompanied autolysis processes strongly modify tissue composition, and lead to MR signal changes, making the validation of biophysical models for in vivo MRI particularly challenging. To better understand the temporal evolution of the fixation process within

Magnetization transfer (MT) of human brain at 7T in the context of a 3D multi-parameter mapping protocol

3D multi-gradient echo MRI can be used to estimate T1, T2*, PD and the magnetization transfer (MT), which is increasingly used for multi-parametricmapping (MPM) of human brain. The increased polarization at 7T compared to lower B0 allows for increased spatial resolution or reduced scantimes. However, SAR restrictions imposed on the MT pulse and B1 inhomogeneity pose challenges. In this work, we pr

Towards the modelling of pedestrian wind speed using high-resolution digital surface models and statistical methods

Wind is a complex phenomenon and a critical fac-tor in assessing climatic conditions and pedestrian comfortwithin cities. To obtain spatial information on near-groundwind speed, 3D computational fluid dynamics (CFD) model-ling is often used. This is a computationally intensive methodwhich requires extensive computer resources and is time con-suming. By using a simpler 2D method, larger areas can b

Mucosal T lymphocyte numbers are selectively reduced in integrin α(E) (CD103)-deficient mice

The mucosal lymphocyte integrin α(E)(CD103)β7 is thought to be important for intraepithelial lymphocyte (IEL) localization or function. We cloned the murine integrin gene encoding α(E), localized it to chromosome 11, and generated integrin α(E)-deficient mice. In α(E)(-/-) mice, intestinal and vaginal IEL numbers were reduced, consistent with the known binding of α(E)β7, to E-cadherin expressed on

Escherichia coli induces transuroepithelial neutrophil migration by an intercellular adhesion molecule-1-dependent mechanism

During bacterial infections at mucosal sites, neutrophils migrate to the mucosa and cross the epithelial barrier. We have examined neutrophil migration across Escherichia coli-stimulated uroepithelial cell layers in an attempt to more fully understand this process. Stimulation of uroepithelial cells with E. coli or interleukin-1α (IL-1α) induced transepithelial neutrophil migration in a time- and

Uroepithelial cells are part of a mucosal cytokine network

This study compared the cytokine production of uroepithelial cell lines in response to gram-negative bacteria and inflammatory cytokines. Human kidney (A498) and bladder (J82) epithelial cell lines were stimulated with either Escherichia coli Hu734, interleukin 1α (IL-1α), or tumor necrosis factor alpha (TNF-α). Supernatant samples were removed, and the RNA was extracted from cells at 0, 2, 6, and

Podocalyxin-like and rna-binding motif protein 3 are prognostic biomarkers in urothelial bladder cancer : A validatory study

Background: Urothelial bladder cancer (UBC) is a disease that often is discovered when the tumour is non-muscle invasive, i.e. in Ta or T1 stage. Some patients will progress into muscle-invasive disease, a potentially deadly condition. Although there are some prognostic models, the need for prognostic and predictive biomarkers is considerate and urgent. Membranous expression of podocalyxin-like pr

Global and domain-specific life satisfaction among older adults with long-term spinal cord injury

Objective: Although life expectancy after spinal cord injury (SCI) has increased, knowledge of life satisfaction and associated factors among older adults with long-term SCI is still very limited. The objective of this study was, therefore, to assess global and domain-specific life satisfaction among older adults with long-term SCI and investigate the association with sociodemographics, injury cha

International multi-institutional bench mark study on dosimetric and volumetric modulation using helical tomotherapy treatment planning for malignant pleural mesothelioma tumors

Determining the most desirable and achievable target dose and organ at risk (OAR) sparing using helical TomoTherapy planning system for mesothelioma treatment plans. A range of planning parameters was used. The reviewers’ ranking assessment (Ranking in Groups: 1 = Good, 2 = Above Average, 3 = Average, 4 = Poor).The overall rankings revealed that a plan with a balanced tradeoff among all planning o

Graphene-Based Metal-Free Catalysis

This chapter focuses on the use of doped carbon nanomaterials in catalysis. The availability of carbon nanotubes in the ‘90s and graphene about 10Â years later, prompted the development of fundamental research and novel nanotechnologies. We discuss this topic from a point of view that links fundamental surface science to the field of catalysis, in order to present the state of the art.
