A general method for finding elementary abelian regular covering projections of finite connected graphs is applied to the Petersen graph. As a result, a complete list of pairwise nonisomophic elementary abelian covers admitting a lift of a vertex-transitive group of automorphisms is given. The resulting graphs are explicitly described in terms of voltage assignments.

We study the topological K-theory spectrum of the dg singularity category associated to a weighted projective complete intersection. We calculate the topological K-theory of the dg singularity category of a weighted projective hypersurface in terms of its Milnor fiber and monodromy operator, and, as an application, we obtain a lift of the Atiyah-Bott-Shapiro construction to the level of spectra.

Facelift surgery is unique in many ways and for 100 years has stood the test of time as the most dramatic, effective, predictable, and accepted cosmetic lower facial procedure. From public misconceptions to patient confusion, a lot of information must be exchanged for successful diagnosis, recovery, and result. It requires a qualified surgeon that operates in a safe environment and knows his or...

the ordinary tensor product of modules is defined using bilinear maps (bimorphisms), that are linear in eachcomponent. keeping this in mind, linton and banaschewski with nelson defined and studied the tensor product in an equational category and in a general (concrete) category k, respectively, using bimorphisms, that is, defined via the hom-functor on k. also, the so-called sesquilinear, or on...

Abstract Droplet impacts on superhydrophobic surfaces may result in complete bouncing, with the absence of contact hysteresis and viscous dissipation leading droplet to fully rebound off surface. This usually happens retraction phase, when retracts back after reaching a maximum spread diameter. Here, we present experimental evidence bouncing phenomenon where sessile hydrophobic surface bounces ...

In this article, which focuses on concepts rather than techniques, the author emphasizes that the best predictor of a good facelift outcome is an already attractive face that has good enough tissue quality to maintain a result past the swelling stage. The author notes that too often, surgeons gravitate toward a particular facial support technique and use it all the time, to often unsatisfactory...

Surgical eyebrow lift has been described by using many different open and endoscopic methods. Difficult techniques and only short time benefits oft lead to patients' complaints. We present a safe and simple temporal Z-incision technique for eyebrow lift in 37 patients. Besides simplicity and safety, our technique shows long lasting aesthetic results with hidden scars and a high rate of patient ...

Similar to random sea waves, forces on the offshore structures due to waves are random. These forces can be mainly divided into two components, namely, inline forces and transverse or lift forces. The random nature of lift forces is more complicated than that of inline forces and both should be combined for design purposes. In the present paper, two different approaches have been used to determ...
