Assessing Undergraduate Sustainability Knowledge at California Polytechnic State University
… higher sustainability knowledge scores (SKS) after taking a structured sustainability curriculum, but also reveals that those post-curriculum SKS of honors students are not significantly different from that of general students after taking 3 courses. The results further indicate that …

The role of sphingosine kinases and SKAM1 in cutaneous wound healing
Sphingosine kinases (SKs) phosphorylate sphingosine to generate the bioactive lipid sphingosine 1-phosphate (S1P). SKs and S1P regulate a diverse range of cellular processes, including cell proliferation, survival, differentiation, migration, smooth muscle cell contraction, inflammation, …

The role of sphingosine kinases and dihydroceramide desaturase in regulating senescence in prostate cancer cells
… bioactive lipid sphingosine-1-phosphate (S1P). SKs have been widely implicated in human cancers and inflammation. This has been demonstrated to be a consequence of the actions of S1P, which acts as a ligand at five G protein-coupled receptors - termed S1P1-5. S1P is also an intracellular …

Understanding late Cenozoic western United States mantle dynamics and surface tectonics using forward-adjoint data assimilation models
… The distribution of shear wave splitting (SKS) in the western U.S. displays several unique patterns including the fast E-W anisotropy from Oregon to Yellowstone, the largely swirl pattern centered in Nevada, and the complex anisotropy around the Rockies. These unique patterns cannot be …

Einfluss verschiedener Typen online basierter Lernplattformen auf die Kompetenz– und Leistungsentwicklung von Schülern
… darstellt und - Sekundär kollaborative Systeme (SKS) bzw. Individuallernsysteme, bei denen eine Kollaboration mit anderen Lernern in den Hintergrund rückt. Der Einsatz der Lernplattformen wird zum einen durch einen Fragebogen zum anderen durch die Messung der Leistungsentwicklung im Vergleich zu …

Aspects of skin cancer diagnosis in clinical practice
… NNE value during the study period was 6.5 (SKs not included). When SKs were included in the calculations the NNE was 6.8. The NNE value decreased with increasing age of the patient and varied for different body locations, with the highest values found for the trunk and the lowest for the …

Seismic anisotropy and mantle flow beneath Africa and Arabia
… the receiver side (XKS including PKS, SKKS, and SKS) is one of the most effective approaches to constrain convective mantle flow patterns. A robust procedure involving automatic and manual batch processing to reliably assess and objectively rank shear-wave splitting parameters were used. The …

Seismic anisotropy and mantle dynamics beneath the central and western United States
… parameters in three phases, i.e. PKS, SKKS and SKS.</p> <p>The dissertation is a combination of two journal papers published in 2014 and 2016, respectively"--Abstract, page iv.</p>

MANTLE FLOW AND TRANSITION ZONE DISCONTINUITIES BENEATH THE CARRIBEAN PLATE: CONSTRAINTS FROM SHEAR WAVE SPLITTING AND RECEIVER FUNCTION ANALYSES
… anisotropy quantified by teleseismic SKS, SKKS, PKS (“XKS”) and local S wave splitting parameters is used to investigate lithospheric deformation and asthenospheric flow beneath the boundary zone of the North American and Caribbean plates and adjacent areas. A total of 4915 XKS and …

The earth's interior from both a seismological and petrological perspective
… measurements of teleseismic shear waves, such as SKS, have been used to estimate the amount and direction of upper-mantle anisotropy worldwide. One of the basic assumptions in making these measurements is that the anisotropy is confined to a single, homogeneous layer. In this thesis, I use both …

Evolution-Inspired Design of Bacterial Biosensors
… between membrane-bound sensor histidine kinases (SKs) and their cognate response regulators (RRs) using the protein language model ESM2. We show that the model is able to identify highly coevolving residues at the SK-RR interface. We then train a dedicated pairing model to predict TCS interactions …

Seismic investigations of the northern Transantarctic Mountains
… performed shear wave splitting analyses on PKS, SKS, and SKKS phases to obtain the splitting parameters (fast axis directions φ and delay times δt). Behind the TAMs front, the anisotropic signature is interpreted as relict fabric “frozen” into the lithosphere from tectonic processes in the …

Identification of novel biomarkers for clinical prognosis in breast cancer
… the expression of S1P signalling proteins (e.g. SKs and S1P₁₋₅ receptors) to identify the impact of expression level of these proteins on clinical outcomes. High SK1 and S1P₄ receptor tumour expression is associated with poor cancer prognosis in ERα negative breast cancer patients. Moreover, high …
