No full textKnot Floer homology, link Floer homology and link detection
No full textWe give new link detection results for knot and link Floer homology inspired
by recent work on Khovanov homology. We show that knot Floer homology detects
, , , , and the link with the
orientation of one component reversed. We show link Floer homology detects
and , for all . Additionally we identify infinitely many
pairs of links such that both links in the pair are each detected by link Floer
homology but have the same Khovanov homology and knot Floer homology. Finally,
we use some of our knot Floer detection results to give topological
applications of annular Khovanov homology
Floer homology, clasp-braids and detection results
No full textMartin showed that link Floer homology detects braid axes. In this paper we
extend this result to give a topological characterisation of links which are
almost braided from the point of view of link Floer homology. The result is
inspired by work of Baldwin-Sivek and Li-Ye on nearly fibered knots.
Applications include that Khovanov homology detects the Whitehead link and
, as well as infinite families of detection results for link Floer
homology and annular Khovanov homology.Comment: 67 pages, 15 figure
Sore throat and subcutaneous emphysema in a 71-year-old patient
No full textA 71-year-old woman was admitted to our emergency department due to sore throat and swelling of the neck and face. She had a history of chronic obstructive pulmonary disease grade 4 based on the Global Initiative for Chronic Obstructive Lung Disease (GOLD). Clinical examination revealed subcutaneous emphysema of the neck and face. CT scan of the thorax and abdomen showed air in the retroperitoneum, ascending through the mediastinum into the neck and face. Laparotomy confirmed the diagnosis of a retroperitoneal colon perforation due to colon diverticulitis. The colon was partially removed followed by a surgical debridement and Hartmann's procedure. The postoperative course was without complications, the clinical symptoms resolved rapidly
Novel Endocuff-assisted Colonoscopy Significantly Increases the Polyp Detection Rate A Randomized Controlled Trial
No full textGoals and Background: Screening colonoscopy for colorectal cancer has proven to reduce mortality rates. Recently the Endocuff (EC), an attachment to the distal tip of the colonoscope, was introduced. The aim of our study was to compare EC-assisted colonoscopies with standard colonoscopies for the detection of colonic polyps. Study: This study is a randomized prospective 2-center trial. The study was conducted at 2 tertiary care centers. Participants: A total of 498 patients [249 males; median age 67 y; interquartile range (IQR), 56-75 y] for colon adenoma screening purposes were included. All patients underwent standard colonoscopy with or without the use of EC. Overall polyp detection rate, the number of colonic polyps, and the polyp distribution in the colon were measured. Difference in recognition of polyps with or without the use of EC was assessed. Statistical analysis was applied. Results: In the EC group, the number of polyps detected per patient was 63% higher [2.00 (IQR, 1.00-4.00) vs. 1.00 (IQR, 1.00-2.25), P < 0.0001]. The polyp detection rate in patients increased by 14% with the use of EC (56% vs. 42%, P= 0.001). For polyp detection, superiority by use of EC could be observed in the sigmoid (P= 0.001) and cecum (P= 0.002) for polyps < 1 cm in diameter. In the EC group, the number of adenomas detected per patient significantly increased by 86% (P= 0.002). No major complications occurred in both groups. Conclusions: The use of the EC is feasible and safe with significantly higher polyp detection rates, especially for those located in the sigmoid region. The cuff system has the potential to improve the accuracy of screening colonoscopies
A combinatorial proof of the invariance of tangle floer homology
No full textElectronic Thesis or DissertationThe aim of this work is to take the combinatorial construction put forward by Petkova and Vértesi for tangle Floer homology and show that many of the arguments that apply to grid diagrams for knots can be applied to grid diagrams for tangles. In particular, we showed that the stabilization and commutation arguments used in combinatorial knot Floer homology can be applied mutatis mutandis to combinatorial tangle Floer homology, giving us an equivalence of chain complexes (either exactly in the case of commutations or up to the size of the grid in stabilizations). We then added a new move, the stretch move, and showed that the same arguments which work for commutations work for this move as well. We then extended these arguments to the context of A-infinity structures. We developed for our stabilization arguments a new type of algebraic notation and used this notation to demonstrate and simplify useful algebraic results. These results were then applied to produce type D and type DA equivalences between grid complexes and their stabilized counterparts. For commutation moves we proceeded more directly, constructing the needed type D homomorphisms and homotopies as needed and then showing that these give us a type D equivalence between tangle grid diagrams and their commuted counterparts. We also showed that these arguments can also be applied to our new stretch move. Finally, we showed that these grid moves are sufficient to accomplish the planar tangle moves required to establish equivalence of the tangles themselves with the exception of one move

Jack Alive / Martin Dead : The Location of the "Author" in Jack London\u27s Martin Eden
No full textThis essay is an attempt to read Martin Eden, Jack Londonʼs autobiographical novel, in terms of the inextricable relationship between the author and the protagonist. Critics have often taken the unbalanced plot and the lack of ironic distance between narrator and character in Martin Eden as the technical weakness of London, but this paper argues that the achievement of this novel owes a great deal to the attachment of London to Martin. The unbalanced structure is a necessary product of the severe struggle of the author to kill his romantic alter ego. // Martin, who aspires to win Ruth Morse, tries to cross class boundaries by making a career of a writer. Even after realizing the emptiness of Ruth, who turns out to be nothing but a typical figure of the bourgeoisie, he somehow persists in loving her. The notion underlying here is that, for Martin, love, career and art are fundamentally inseparable. He objects to the aestheteʼs view of Brissenden on account of his separation of art from career. Martinʼs identity and life consist only in the triunity of love/career/art; the alternative is the repudiation of life. Thus, the unnatural delay of his disappointment in love can be regarded as Londonʼs strategy to set the suicide of Martin as the necessary consequence of the story. // By finishing the story and killing Martin, London finally detaches himself from Martin, reconstructs his self, and, unlike Martin, survives as a professional writer. In this sense, Martin Eden is a story about “writerʼs self-reconstruction.
