Knotting of optical vortices
Optical vortices form three-dimensional lines of darkness in scalar light. They are places where the phase becomes undefined and hence singular in value. We study the ability of optical vortices to form knots and links of darkness in scalar optical fields. We describe a construction to create …

Knot/Knotting Practice in Craft and Space
Knot/knotting Practice in Craft and Space is a three part research-creation project that used a study of knotting techniques to locate craft in an expanded field of spatial practice. The first part consisted of practical, studio based exercises in which I worked with various natural and synthetic …

Something New, Something Old: Combining Conductive Fibers and Classical Tatting Techniques for Lace Structured Circuits
… type of lace is fairly stiff, consisting of self-knotting rings and chains that form a design. There are similarities in structure of a knot around a core thread to insulation around a wire. With the use of cotton thread knots around a core conductive thread, the structure of the lace becomes a …

The Enhanced Linking Number and its Applications
… that preserves all notions of intra-component knotting and inter-component linking.

A Transfer Matrix Approach to Studying the Entanglement Complexity of Self-Avoiding Polygons in Lattice Tubes
… for small tube sizes, and exact enumeration of knotting distributions are obtained for small SAP sizes. Also, a novel sampling procedure that utilizes the generated transfer matrices is implemented to obtain independent uniformly distributed random samples of large SAPs in tubes. Using these …

Folding knotworks: a conceptual, sensual and socio-political encounter
… and writing. The page becomes a weave: words knotting into images and material gestures. Knotwork emerges as a living, relational methodology, restless and generative, rethreading experience as it loops and returns through loss, a conceptual, sensual, socio-political encounter.

Transforming Personal Daily GPS Data Through Performances: Movement, Memory and Time
… through public drawing, narrating and collective knotting. Each of the pieces is related to the respective central themes of movement, memory and time. Through performance methodologies involving durational and slow processes, Ishow how all the works deal with means of visualising and …

Studying self-entangled DNA at the single molecule level
… observed phenomenon of the compression and self-knotting of a single DNA molecule in the presence of an electric field. We then use this mechanism to study the process of stretching complex DNA knots in an extensional field. These knots dramatically alter the way DNA stretches in two ways: an …

LineFORM: designing interactions with actuated curve interfaces
… various tangible interactions, including knotting, wrapping, tying, and connecting. Lines are also used to represent abstract information, from the original drawings using line from thousands of years ago, to now when they are used to compose digital geometrical models through wireframe or …

Zanzibar Pizza Hut: Stone Town’s Duckorated Sheds
… they exist in and amplify multiple temporalities—knotting together the supposedly rupturing moments of the end of slavery, the inauguration of colonial power, and the late-millennium embrace of corporate multinational capitalism. The logics of Duckorated Sheds suggest less a rupturing event than a …

Soliton interactions and bound states
… string. Their charge is related to the string's knotting and twisting. In this chapter we include an extra mass term in the Skyrme-Faddeev theory; this gives solitons which are exponentially localised. We then explore the infinite-coupling case, which gives compact Hopons. This chapter is part of …

Topology and geometry-based methods for quantifying the complexity of protein structures
… the proteins. The data also demonstrate that knotting of a tau protein in the unfolded ensemble is a possible but rare event.

Tactile Textile
… into verbs. These verbs of weaving, pleating, knotting etc. is then used as tools to analyze the site and its context in context of the act -of textile manipulation itself. From this, the area of study is broken up into pattern pieces. This unlocks a new perspective on how each of these pieces' …

Investigation and Modelling of the Yarn Splicing Process
… in the 1960's to overcome the deficiencies of knotting of textile yarns, but there has been little research into splicing because it is a complicated process, very difficult to observe. A splice is formed very quickly, using highly turbulent air within a closed environment. Direct observation …

Searching for Healing Amidst the Genocidal Logic: Fragmentary Exiled Bosnian (Im)Possibilities
… a both/and perspective that foregrounds the knotting personal and political dimensions. I use the partially analytical mind-body-duša (soul) composition to highlight lived realities and to approach ongoing reconfigurations of subjectivity and affect. I term the type of research and writing …
