Abstract:
A knot in a thickened surface [Formula: see text] is a smooth embedding [Formula: see text], where [Formula: see text] is a closed, connected, orientable surface. There is a bijective correspondence between knots in [Formula: see text] and knots in [Formula: see text], so one can view the study of knots in thickened surfaces as an extension of classical knot theory. An immediate question is if other classical definitions, concepts, and results extend or generalize to the study of knots in a thickened surface. One such famous result is the Fox–Milnor Theorem, which relates the Alexander polynom

For a given two-dimensional compact oriented surface Σ with boundary, we define invariants with 4 variables for links in Σ×[0, 1]. These invariants restrict to the two-variable HOMFLY polynomials when Σ=D2. Some comments are made about the action of the mapping class group of Σ on these invariants.

Abstract:
Using a combinatorial argument, we prove the well-known result that the Wirtinger and Dehn presentations of a link in 3-space describe isomorphic groups. The result is not true for links [Formula: see text] in a thickened surface [Formula: see text]. Their precise relationship, as given in [R. E. Byrd, On the geometry of virtual knots, M.S. Thesis, Boise State University (2012)], is established here by an elementary argument. When a diagram in [Formula: see text] for [Formula: see text] can be checkerboard shaded, the Dehn presentation leads naturally to an abelian “Dehn coloring group,” an is

Abstract:
Abstract This study used clinopyroxene (cpx) compositions and zircon Hf-O isotopes of Eocene adakitic rocks (EARs) from the Qiangtang block to resolve the mechanism(s) responsible for the formation of the central Tibetan Plateau. The two leading and opposing hypotheses for the origin of these rocks are (1) partially molten foundered lower crust, and (2) partial melting of continentally subducted upper crust. The consensus is that some crustal sources within the mantle have reached eclogite facies, while evidence remains insufficient. Reverse zonation for cpx in high Mg# andesitic samples shows

Abstract:
The interaction of a convected wake with a compressor blade boundary layer was investigated. Measurements within a single-stage compressor were made using an endoscopic PIV system, a surface mounted pressure transducer, hotfilms and hotwire traverses, along with CFD simulations. The wake/leading-edge interaction was shown to lead to the formation of a thickened laminar boundary-layer, within which turbulent spots formed close to the leading edge. The thickened boundary-layer became turbulent and propagated down the blade surface, giving rise to pressure perturbations of 7% of the inlet dynamic

Abstract:
Two link diagrams on compact surfaces are strongly equivalent if they are related by Reidemeister moves and orientation preserving homeomorphisms of the surfaces. They are stably equivalent if they are related by the two previous operations and adding or removing handles. Turaev and Turner constructed a link homology for each stable equivalence class by applying an unoriented topological quantum field theory (TQFT) to a geometric chain complex similar to Bar-Natan's one. In this paper, by using an unoriented homotopy quantum field theory (HQFT), we construct a link homology for each strong equ

Abstract:
Mikhail Khovanov developed a bi-graded homology theory for links in the 3-sphere. Khovanov's theory came from a Topological quantum field theory (TQFT) and as such has a geometric interpretation, explored by Dror Bar-Natan. Marta Asaeda, Jozef Przytycki and Adam Sikora extended Khovanov's theory to I-bundles using decorated diagrams. Their theory did not suggest an obvious geometric version since it was not associated to a TQFT. We develop a geometric version of Asaeda, Przytycki and Sikora's theory for links in thickened surfaces. This version leads to two other distinct theories that we also

Abstract:
Osteoarthritis (OA) is the commonest condition to affect synovial joints, but although any synovial joint can be affected, most studies of pathology relate to large joints (knees and hips). OA involves the whole joint and pathological alterations typically occur in all joint tissues. Established OA is characterized by a mixture of tissue loss and new tissue production resulting in focal loss of articular hyaline cartilage together with bone remodelling and osteophyte formation. Articular cartilage may show increased thickness in the earliest stages of OA with increased numbers of hypertrophic

Abstract:
Gropes, towers, and skyscrapers are carefully defined. These are the objects that the rest of Part II studies and seeks to construct. All three are 4-manifolds with boundary, obtained from stacking thickened surfaces on top of one another. Gropes are constructed from thickened orientable surfaces with positive genus, each stage attached to a symplectic basis of curves for the homology of the previous stage. Towers have an additional type of stage obtained from plumbed thickened discs. A skyscraper is the endpoint compactification of an infinite tower. An introduction to endpoint compactifications is included. The notion of a good group is also defined.

Abstract:
Presumably in constructing the sidewalk, the bones from these shallow burials were disposed of elsewhere. Remains of five adults and one child were excavated. Seven subadult teeth were surface-collected around a hole at the western edge of the site. Being buried in moist sand meant that most bones excavated were fragmented. Bones and teeth were examined for evidence of pathologies. This small sample is not representative of the community, but the pathologies provide insight on these persons’ lives. The linea aspera on the only femur excavated is fairly robust. The individual’s sex was indeterminate, but this ambiguity reinforced the point that both men and women in this community engaged in physically demanding work. Cranial fragments from two individuals were thickened, an indicator of anemia resulting from nutritional deficiency or disease. Cribra orbitalia was noted in the eye socket of one individual, another indicator of nutritional deficiency. Two of the child’s incisors have transverse lines, evidence of enamel hypoplasia, an indicator of infectious disease and nutritional stress. Individuals buried in this cemetery were likely of low social status, living in congested and unsanitary conditions with limited food. These pathologies raise questions about the extent these conditions existed among African-Bahamian communities. Economic opportunities for free and enslaved workers would have been limited.
