We revisit the problem of the cosmic microwave background on the largest angular scales. Temperature multipoles of any order factor naturally into a direct product of axial quantities and cosets. Striking coincidences exist among the axes associated with the dipole, quadrupole, and octupole CMB moments. These axes also coincide well with two other axes independently determined from polarization...

Although many algorithms have been proposed for evaluating XPath queries containing child and descendant axes and predicates (XPATH/,//,[ ]) against XML data, there are very few efforts towards developing algorithms for processing path expressions with other axes namely, following, preceding, following-sibling and preceding-sibling. In this article, we demonstrate that the conventional twig-str...

Astrophysical bodies often have magnetic axes not aligned with their rotational axes. For instance, the magnetic axes of Earth and Uranus have tilt angles of 11 ̊ and 60 ̊ with respect to their rotational axes. The Earth’s magnetic field is attributed to interactions between the solid iron core, the outer molten core, and planetary rotation (Coe and Glatzmaier, 2006). Modeling shows that the same...

For a 5-axis machine tool, the 3D volumetric tool-tip positioning accuracy is very important for parts accuracy and quality assurance. Just calibrate the 3 linear axes and the 2 rotational axes is not enough. There are straightness errors for each of the 3 linear axes, and squareness errors between the 3 linear axes, misalignment errors between the linear axes and the rotary axes. Hence, it is ...

Vertebrate limbs display three obvious axes of asymmetry. These three axes are referred to as proximal-distal (Pr-D; shoulder to digit tips), anterior-posterior (A-P; thumb to little finger), and dorsal-ventral (D-V; back of hand to palm). At a molecular level, it is now possible to define the signals that control patterning of each of the three axes of the developing limb. These signals do not...

We consider a system of outflows ejected from low mass young stars embedded in the tips of elephant trunks. We assume that these outflows have axes which are intrinsically perpendicular to the axes of the host elephant trunks. We then derive the distribution function expected for the angle between the projections of the outflow and elephant trunk axes on the plane of the sky. These distribution...

As the capacity to summarize of the preference map diminishes with the number of consumers (the number of axes to interpret increases), a non-metric PCA is sometimes used to reduce the number of necessary axes. The non-metric PCA consists of a monotone transform of the data so that the variability explained by the k (k=2 or 3) first axes is maximized. This transform implies that we consider the...

The responses of two cultivars of soybean (Merr.) to a chilling treatment (4 C for first hour of imbibition) were compared. The germination of cv. Biloxi was unaffected by the treatment, while the germination of cv. Fiskeby was reduced. The phospholipid fatty acids of dry axes of the two cultivars were very similar, and, thus, could not be correlated with their responses to chilling. The fatty ...

The paper presents the original contributions on structural and functional analysis of numerical controlled (NC) axes of industrial robots (IR) with electric driving system. Main purpose of the paper is to define and validate an assisted selection procedure of IR’s NC axes optimal structure imposed specification accordingly IR’s output for performance level. For this purpose a complex assisted ...

background: evaluating the landmarks for rotation of the distal femur is a challenge for orthopedic surgeons. although the posterior femoral condyle axis is a good landmark for surgeons, the surgical transepicondylar axis may be a better option with the help of preoperative ct scanning. the purpose of this study was to ascertain relationships among the axes’ guiding distal femur rotational alig...
