[1] We present observations of seasonal variations in polygonal crack patterns located in a polar trough on the south polar cap of Mars; previously, there was no direct observation showing that these patterns change. Polygonal patterns on Mars are attributed to thermal contraction cracking, which is commonly observed in periglacial environments on Earth. In this paper we discuss observations ba...

As hernia mesh implants are used to reinforce the abdominal wall, several complications can occur, such as recurrence, pain, seroma formation and infection, depending on their biocompatibility. The polymer coated knitted is repair hernias by providing a flexible scaffold. objective of this study was assess skin sensitisation potential polar non-polar extract In Vitro degradation Vivo pattern fo...

[1] The time-variable structure of Ganymede’s magnetosphere is studied by means of resistive MHD simulations. Using the magnetometer measurements of the Galileo spacecraft in the first few Ganymede flybys as examples, we find that the plasma flow pattern inside the Ganymedian magnetosphere could be subject to significant changes. Furthermore, the boundary of the polar cap dividing the open magn...

In this paper, polar and spherical Fourier Analysis are defined as the decomposition of a function in terms of eigenfunctions of the Laplacian with the eigenfunctions being separable in the corresponding coordinates. Each eigenfunction represents a basic pattern with the wavenumber indicating the scale. The proposed transforms provide an effective radial decomposition in addition to the well-kn...

The plant vascular system provides transport and support capabilities that are essential for plant growth and development, yet the mechanisms directing the arrangement of vascular bundles within the shoot inflorescence stem remain unknown. We used computational and experimental biology to evaluate the role of auxin and brassinosteroid hormones in vascular patterning in Arabidopsis. We show that...

2. Three interpretations of negative polar interrogatives • Ladd (1981) distinguishes two varieties of negative polar interrogatives, which are epistemically biased toward the opposite directions. o the “outside NEG” question: conveys a positive bias; “the speaker believes a proposition P and wants confirmation” o the “inside NEG” question: conveys a negative bias; “the speaker has just inferre...

Many spatio-temporal phenomena (both natural and human) change in time cycles, e.g., seasonal change of weather and pattern of people’s daily activities, which required a cyclic view of time. However, most GIS systems and cartographic representation adopt Cartesian Coordinate Systems (CCSs), which force time to be perceived as a linear dimension. Therefore, the cyclic change cannot be effective...

This study examines the temporal evolution of the tropospheric circulation following large-amplitude variations in the strength of the Southern Hemisphere (SH) stratospheric polar vortex in data from 1979 to 2001 and following the SH sudden stratospheric warming of 2002. In both cases, anomalies in the strength of the SH stratospheric polar vortex precede similarly signed anomalies in the tropo...

A 52-year-old male presented with a 25-year history of decreasing vision. Best corrected visual acuity was 0.3 in his right and 0.2 in his left eye. Fundoscopic examination showed bilateral symmetric atrophy of the retinal pigment epithelium and choriocapillaris in the posterior polar areas between vascular arcades and surrounding the optic disc. On fluorescein angiography, the large choroidal ...

Following the results of cite{Med}, regarding the Aluthge transform of polynomial matrices, the symbolic computation of the Duggal transform of a polynomial matrix $A$ is developed in this paper, using the polar decomposition and the singular value decomposition of $A$. Thereat, the polynomial singular value decomposition method is utilized, which is an iterative algorithm with numerical charac...
