Truth Recovery: an interview with Lance Olsen
No full textLance Olsen is author of more than 30 books of and about innovative writing, including, most recently, the novels Skin Elegies (Olsen, 2021) and Always Crashing in the Same Car (Olsen, 2023). His short stories, essays, and reviews have appeared in hundreds of journals and anthologies. A Guggenheim, Berlin Prize, D.A.A.D. Artist-in-Berlin Residency, Rockefeller Foundation Bellagio Center, two-time N.E.A. Fellowship, and Pushcart Prize recipient, as well as a Fulbright Scholar, he teaches experimental narrative theory and practice at the University of Utah.
This interview is a dialogue about the blurring of fiction and non-fiction, creative writing's place and role in the 21st Century, and Olsen's commitment to experimental writing and his use of processes, concepts and ideas to subvert what many regard as traditional writing and storytelling. It also considers how narrative can be deconstructed, reconfigured, re-constructed and re-invigorated; the possibilities and ethics of remix and appropriation; the failures of mainstream publishing; and how we can or might represent our complex and confusing lives on the page. Olsen's use of (at times oppositional and contradictory) multiple or polyphonic voices, changing points of view, stylistic mutation and contrasting forms, along with a frequent blurring of story, script, prose poetry and stream-of-consciousness writing facilitate and encourage the reader to assemble their own narratives, without this ever being anything other than enjoyable.
It is to be hoped that the interview will encourage and assist others to rethink creative-writing pedagogy, or at least consider the theoretical assumptions behind normative teaching and writing
Comparative study between traditional and coherent jet oxygen lance interaction with molten pool
No full textAs an advanced nozzle and because of protective gas around the main oxygen hole, coherent jet oxygen lance can make the jet concentrated with higher kinetic energy. In this paper, a coherent jet oxygen lance is tried to be made with small oxygen holes around the main oxygen hole on the traditional oxygen lance. Flow characteristic of coherent jet oxygen lance and traditional oxygen lance are simulated by CFD software. The results show that, compared with traditional oxygen lance, the attenuation of coherent jet oxygen lance is slow on the center axis, impact depth is deep, the liquid region velocity is high in the center of molten pools, flow ability of liquid steel is good in molten pools. Coherent jet oxygen lance with the suitable lance height can replace traditional top-bottom blowing mode
Developing consistency by consensus: Avoiding fiat in language revitalization
No full textLinguistic !eld work in Tlingit is occurring cooperatively within a triangle of linguists, teachers, and speakers who collaborate electronically and in person between Vancouver, British Columbia, Amherst, Massachusetts, and Juneau, Alaska. Their work makes it into the classroom almost immediately as they collectively refine methods of language documentation, teaching, and revitalization. While the group that works at the deepest linguistic levels of the language is small, they are wide ranging in their backgrounds and geographic locations. This makes small- group email messages and discussions the method of reaching consensus, which opens the door for quick decisions that are then implemented in documentation and teaching methodologies.
Historically, Tlingit has been impacted the most by external forces. At times, those were devastating entities like boarding schools, missionaries, and community-wide racism. At others, they were miraculous in terms of language documentation and curriculum development by missionaries and linguists. Today, There are three highly active linguists, in three different locations, and each of them are making tremendous contributions in documenting and understanding linguistic phenomena that native speakers knew intrinsically, but that teachers and students often found difficult if not impossible to document and predict. These three are all working with varying degrees of traits that are external and internal to Tlingit land, culture, and language.
There is a non-Tlingit linguist, (co-author), living in Juneau and having the most direct contact with fluent speakers, and often is associated with some of the largest gatherings of speakers of Tlingit today. Then there is the first Tlingit linguist, (author), who is studying outside of Tlingit country and feeding materials into the classroom and through speakers remotely, and is creating handbooks and presentations that will change the way Tlingit verbs and grammar are understood, taught, and learned. Finally, there is a non-Tlingit linguist (co-author), living in Massachusetts and helping refine some of the little-understood territories within Tlingit, like insubordinate clauses and other phenomena.
The linguistic discoveries made by these three are implemented into newly developing curriculum and teaching methodologies by the author. He is the first tenure-track faculty in Alaska Native Languages at the university and works collaboratively with the co-authors, and local speakers and teachers to implement shifts in language documentation and teaching. These linguistic activities are combining with an promotional campaign that is initiating a true revitalization for the Tlingit language

Effect of Swirl Angle on Interaction between Swirl Oxygen Lance Jet and Melt Pool
No full textIn order to clarify the action law of the swirl oxygen lance jet on the melt pool of the converter and to determine the optimal swirl angle of the swirl oxygen lance for the 120t converter, this study establishes the gas-liquid two-phase flow model of the oxygen lance with different swirl angles based on the realizable k-ε model and the VOF multiphase flow model. The gas-liquid interface behavior during the interaction between the jet and the molten pool was analyzed, and the flow pattern of molten steel in the molten pool was mainly investigated. The results show that compared with traditional oxygen lance, the rotating oxygen lance jet enhances the stirring of the melt pool and intensifies the fluctuation of the melt pool liquid level. The depth of the impact cavity decreases with the increase of the swirl angle, but the diameter of the impact cavity increases with the increase of the swirl angle. When the jet with a swirl angle of 10° impacts the surface of the melt pool, the turbulence energy obtained by the molten steel is the highest, the average flow velocity inside the melt pool is the highest, and the molten steel is stirred more thoroughly, achieving better melting effects
Add-on perampanel in Lance–Adams syndrome
No full textAbstractPerampanel (PER) is the first-in-class selective, noncompetitive α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor antagonist that has been licensed and marketed as antiepileptic drug (AED) indicated for patients with partial-onset and primary generalized tonic–clonic seizures. A positive effect was reported in some patients with epileptic myoclonic jerks in idiopathic generalized epilepsy and in progressive myoclonic epilepsy.We treated a male patient with posthypoxic nonepileptic myoclonus (Lance–Adams syndrome) with add-on PER and achieved an almost complete cessation of jerks. This effect was reproducible and, therefore, we suggest that it might be worth trying PER in comparable cases

Antipodal Self-Duality for a Four-Particle Form Factor
No full textWe bootstrap the symbol of the maximal-helicity-violating four-particle form factor for the chiral part of the stress-tensor supermultiplet in planar N=4 super-Yang-Mills theory at two loops. When minimally normalized, this symbol involves only 34 letters and obeys the extended Steinmann relations in all partially overlapping three-particle momentum channels. In addition, the remainder function for this form factor exhibits an antipodal self-duality: It is invariant under the combined operation of the antipodal map defined on multiple polylogarithms—which reverses the order of the symbol letters—and a simple kinematic map. This self-duality holds on a four-dimensional parity-preserving kinematic hypersurface. It implies the antipodal duality recently noticed between the three-particle form factor and the six-particle amplitude in this theory.We bootstrap the symbol of the maximal-helicity-violating four-particle form factor for the chiral part of the stress-tensor supermultiplet in planar super-Yang-Mills theory at two loops.
