Quasi-Optimal Arithmetic for Quaternion Polynomials
Creators: name: Ziegler, Martin
Publisher: name: arXiv
Year: 2003
Subjects: subject: Symbolic Computation (cs.SC)
subject: FOS: Computer and information sciences
subject: I.1;F.2.1

description: Fast algorithms for arithmetic on real or complex polynomials are well-known and have proven to be not only asymptotically efficient but also very practical. Based on Fast Fourier Transform (FFT), they for instance multiply two polynomials of degree up to N or multi-evaluate one at N points simultaneously within quasi-linear time O(N.polylog N). An extension to (and in fact the mere definition of) polynomials over the skew-field H of quaternions is promising but still missing. The present work proposes three such definitions which in the commutative case coincide but for H turn out to differ, each one satisfying some desirable properties while lacking others. For each notion we devise algorithms for according arithmetic; these are quasi-optimal in that their running times match lower complexity bounds up to polylogarithmic factors.

description: Mutations with beneficial effects in one sex can have deleterious effects in the other. Such ‘sexually antagonistic’ (SA) variants contribute to variation in life-history traits and overall fitness, yet their genomic distribution is poorly resolved. Theory predicts that SA variants could be enriched on the X chromosome or autosomes, yet current empirical tests face two formidable challenges: (i) identifying SA selection in genomic data is difficult; and (ii) metrics of SA variation show persistent biases towards the X, even when SA variants are randomly distributed across the genome. Here, we present an unbiased test of the theory that SA variants are enriched on the X. We first develop models for reproductive FST—a metric for quantifying sex-differential (including SA) effects of genetic variants on lifetime reproductive success—that control for X-linked biases. Comparing data from approximately 250 000 UK Biobank individuals to our models, we find FST elevations consistent with both X-linked and autosomal SA polymorphisms affecting reproductive success in humans. However, the extent of FST elevations does not differ from a model in which SA polymorphisms are randomly distributed across the genome. We argue that the polygenic nature of SA variation, along with sex asymmetries in SA effects, might render X-linked enrichment of SA polymorphisms unlikely.

description: My thesis research investigates how the physical and material processes of painting can elicit memory and dreaming. Through the material research of painting, this thesis explores what memory could look like and how it behaves. Painting for me becomes a mode to access personal memories and imagine alternative realities. My physical studio space becomes a dwelling place for dreaming. Mixing acrylic paint, engaging with colour, building shaped canvases and putting brush to canvas all encompass a process-based approach to research
within my thesis. In the large-scale shaped canvases, imagery of doorways and windows from my previous homes function as a place of origin. Memories, even those unremembered, line the walls of the spaces we grew up in, they are embedded and woven into its architecture. This imagery is used as a space to hold and embrace playful mark-making and colour application. While their reference to home architecture is rooted in real spaces, my paintings are also imaginary. Moments spoken and movements made in these spaces are transformed into form and colour. The painted mark traces memory; with liveliness it manifests into a visual representation of daydreaming.

MIGNEX Policy Brief D6.6 (a) - What are the 'root causes' of migration?
Creators: name: Hagen-Zanker, Jessica
name: Carling, Jørgen
Publisher: name: Peace Research Institute Oslo
Year: 2023

description: The term ‘root causes of migration’ is fuzzy and contested but has been widely used since the 1980s. We provide a precise definition of the ‘root causes of migration’, examine how they work, and discuss whether the concept is useful.

Key Takeaways

‘Root causes’ typically represent hardships that are important to address in order to improve people’s lives, regardless of their effects on migration.

Managing migration by ‘tackling the root causes’ can be ethically and politically flawed because it rests on the idea of migration as a problem to be solved.

It is also unlikely to work because ‘root causes’ make up only part of the drivers of migration, and even have contradictory impacts on migration.

Non-intentional performance practice in John Cage's Solo for Sliding Trombone
Creators: name: Chilton, James Gregory
Publisher: name: University of British Columbia
Year: 2011

description: This dissertation provides a study guide to aid trombonists in understanding and appreciating the Solo for Sliding Trombone (1957-58), one of the many solo parts from the Concert for Piano and Orchestra (1957-58) by John Cage (1912-1992). This seldom-performed piece of contemporary music is often misunderstood and is overlooked as an important part of the trombone repertoire. This document aims to help trombonists seeking to perform unaccompanied trombone music to develop an understanding of Cage's aesthetic of non-intentional performance and a greater interest in learning this work. In particular, this dissertation addresses the question of how one can perform the Solo with non-intention in spite of the fact that practicing and rehearsing are required to play the work. The Solo score presents new challenges for the trombonist in terms of using all parts of the trombone, as well as a wide selection of mutes, to produce various sounds and timbres in ways never before conceived for the instrument. To approach this work, the trombonist must also reconsider his or her performance practice; they must learn to maintain extreme patience in performance and must transform the way they listen to and treat "silence." This work was the first indeterminate solo composition for the instrument. This document considers the context and compositional process for this piece, provides guidelines for performing the Solo, examines recordings of the work, and discusses its influence on later compositions for trombone. Thus, this dissertation presents the first extensive scholarly study of Cage's Solo for Sliding Trombone.

description: We searched for Tc in a sample of long period variables selected by stellar luminosity derived from Hipparcos parallaxes. Tc, as an unstable s-process element, is a good indicator for the evolutionary status of stars on the asymptotic giant branch (AGB). In this paper we study the occurrence of Tc as a function of luminosity to provide constraints on the minimum luminosity for the third dredge up as estimated from recent stellar evolution models. A large number of AGB stars above the estimated theoretical limit for the third dredge up are found not to show Tc. We confirm previous findings that only a small fraction of the semiregular variables show Tc lines in their spectra. Contrary to earlier results by Little et al. (1987) we find also a significant number of Miras without Tc. The presence and absence of Tc is discussed in relation to the mass distribution of AGB stars. We find that a large fraction of the stars of our sample must have current masses of less than 1.5 M_{\sun}. Combining our findings with stellar evolution scenarios we conclude that the fraction of time a star is observed as a SRV or a Mira is dependent on its mass.

description: Cholangiocarcinoma (CCA) is a rare and fatally aggressive cancer of the biliary tract. Due to its heterogeneous nature, silent presentation, and wavering response to chemotherapy, CCA-associated mortality accounts for ~2% of cancer-afflicted deaths yearly[1]. Cholelithiasis/gallstones (GS) are hardened deposits, usually cholesterol, that form in the gallbladder (GB) and cause severe symptoms mainly inflammation and abdominal pain. They have been termed a possible risk factor for CCA however no definitive link or evidence exists on the molecular level [2,3].

description: We demonstrate the existence of static stable spherical fluid shells in the Schwarzschild-Rindler-anti-de Sitter (SRAdS) spacetime where $ds^2 = f(r)dt^{2} -\frac{dr^{2}}{f(r)}-r^{2}(dθ^2 +\sin ^2 θdϕ^2)$ with $f(r) = 1 -\frac{2Gm}{r} + 2 b r -\fracΛ{3}r^2$. This is an alternative to the well known gravastar geometry where the stability emerges due to the combination of the repulsive forces of the interior de Sitter space with the attractive forces of the exterior Schwarzschild spacetime. In the SRAdS spacetime the repulsion that leads to stability of the shell comes from a negative Rindler term while the Schwarzschild and anti-de Sitter terms are attractive. We demonstrate the existence of such stable spherical shells for three shell fluid equations of state: vacuum shell ($p=-σ$), stiff matter shell ($p=σ$) and dust shell ($p=0$) where $p$ is the shell pressure and $σ$ is the shell surface density. We also identify the metric parameter conditions that need to be satisfied for shell stability in each case. The vacuum stable shell solution in the SRAdS spacetime is consistent with previous studies by two of the authors that demonstrated the existence sf stable spherical scalar field domain walls in the SRAdS spacetime.

description: Origin and early evolution of animal development remain one of many deep, unresolved problems in evolutionary biology. As a compelling case for the existence of pre-Cambrian animals, the Ediacaran embryo-like fossils (EELFs) from the Weng'an Biota (approx. 609 Myr old, Doushantuo Formation, South China) have the great potential to cast light on the origin and early evolution of animal development. However, their biological implications can be fully realized only when their phylogenetic positions are correctly established, and unfortunately, this is the key problem under debate. As a significant feature of developmental biology, the cell division pattern (CDP) characterized by the dynamic spatial arrangement of cells and associated developmental mechanisms is critical to reassess these hypotheses and evaluate the diversity of the EELFs; however, their phylogenetic implications have not been fully realized. Additionally, the scarcity of fossil specimens representing late developmental stages with cell differentiation accounts for much of this debate too. Here, we reconstructed a large number of EELFs using submicron resolution X-ray tomographic microscopy and focused on the CDPs and associated developmental mechanisms as well as features of cell differentiation. Four types of CDPs and specimens with cell differentiation were identified. Contrary to the prevailing view, our results together with recent studies suggest that the diversity and complexity of developmental mechanisms documented by the EELFs are much higher than is often claimed. The diverse CDPs and associated development features including palintomic cleavage, maternal nutrition, asymmetric cell divisions, symmetry breaking, establishment of polarity or axis, spatial cell migration and differentiation constrain some EELFs, if not all, as total-group metazoans.This article is part of the theme issue ‘How Chinese fossils and palaeontological research impact our understanding of major evolutionary transitions’.

description: Considering the potential of critical observation, the application of pigment, and the function of surface, this thesis project is a series of observations from life. This conceptual body of work consists of paintings, drawings, and artist’s books. I am interrogating material value systems and engaging with the act of collecting. The recorded items include the minute, the preliminary, the ephemeral, and the peculiar. Contingent on the impulse to understand and record, the subject of the work is inquiry. Within the act of study, representational imaging occurs without the influence of the camera as a tool. This serves to strain the relationship between a captured moment and contemporary systems of image consumption. Affected by the labour and time involved in rendering, the paintings and drawings are a record to the capacity of a moment. These spaces left undone are for breath, for being made aware of nothingness, and to contextualize noticing. The painted images are grasping at the poetics of the everyday, and their materiality subsequently references a body in space.

description: Historical views of Asia as an evolutionary ‘backwater’ are associated with the idea that Homo erectus experienced long periods of stasis and ultimately went extinct. However, recent discoveries of well-dated Middle Pleistocene hominin fossils in China have considerably challenged these ideas and provide sufficient data to propose a testable model that explains the patterning of variation in Middle Pleistocene China, and why it changed over time. A series of hominin fossil studies comparing earlier-Middle and later-Middle Pleistocene groups confirm that the expressions of certain traits shift around 300 ka. Fossils from the later Middle Pleistocene are more variable with a mix of archaic traits as well as ones that are common in Western Eurasian early H. sapiens and Neanderthals. The period around 300 ka appears to have been a critical turning point for later Middle Pleistocene morphological changes in China. It coincides with a phase of climatic instability in the Northern Hemisphere between Marine Isotope Stages 12 and 10 that would have led to changes in gene flow patterning, and regional population survival/extinction. This localized and testable model can be used for future explorations of hominin evolution in later Pleistocene eastern Eurasia.This article is part of the theme issue ‘How Chinese fossils and palaeontological research impact our understanding of major evolutionary transitions’.
title: A study of pupil participation in learning : factors which promote or undermine inclusion
Creators: name: Bailey, Ruth S.
Publisher: name: The Open University
Year: 2004

description: This small-scale piece of practitioner research centres on the participation and learning experience of one group of year 7/8 pupils. My aim was to increase pupil participation in learning. I considered the pupil experience of inclusion and factors which promoted or undermined participation in learning. The investigation is in two phases. The first stage is a case study in which I investigate the school's organisational culture and how the features of school impinge on pupils' participation and inclusion. The second phase is classroom-based research, which is divided into four action cycles, each progressively focusing on an improvement in pupil participation in learning,which emerged from the previous cycle.

Findings showed that the biggest barriers to pupils' learning were the school's organisational culture (which led to pupils' low self-esteem), over reliance on teacher support and lack of autonomy. Pupils' participation improved, together with their self-esteem by being given a choice and a voice, by being supported in identifying their learning styles and by teachers having high expectations of them in completing tasks which made sense and had purpose.

description: Extended Red Emission (ERE) is a widely observed optical emission process, present in a wide range of circumstellar and interstellar environments in the Milky Way galaxy as well as other galaxies. Definitive identifications of the ERE carriers and the ERE process are still a matter of debate. Numerous models have been proposed in recent decades, often developed without consideration of the growing body of observational constraints, which by now invalidate many of these models. This review focuses on the most well-established observational constraints which should help to delineate the way toward a generally accepted explanation of the ERE and an understanding of its place in the radiation physics of the interstellar medium.

The investigation of a novel BRCA2-associated gene, EMSY, on chromosome 11Q13 in breast and ovarian cancer
Creators: name: Brown, Lindsay Anne
Publisher: name: University of British Columbia
Year: 2011

description: EMSY is a novel gene encoding a protein that binds to the tumor suppressor BRCA2. EMSY maps to 11q13, a region commonly amplified in breast cancer, and is located 6 Mb telomeric to CCND1. However, the role of EMSY amplification in breast and ovarian cancer is largely unknown. Here we present evidence that EMSY is commonly amplified in breast cancer, and associated with a poor outcome in several pathological subsets of breast cancer. EMSY gene amplification is a less common event in BRCA2 mutation carriers, providing evidence to support the potential role o f EMSY as surrogate for BRCA2 loss in sporadic breast cancer. In ovarian cancer, EMSY amplification is associated with high grade ovarian carcinomas, and is a frequently amplified element o f the 11q13 amplicon in ovarian cancer. A more detailed analysis of the 11q13 amplicon, which harbors numerous oncogenes including CCND1, EMSY, PAK1, Rsf-1, and GAB2, demonstrated that all five genes are frequently amplified in ovarian carcinomas and are specifically associated with serous carcinomas. Lastly, we wanted to determine whether EMSY overexpression shares similar biological features with loss o f BRCA2 function. Overexpression of a 5' fragment of EMSY induces a chromosomal instability phenotype in human breast epithelial cells that is similar to that of BRCA2 deficient cells. Furthermore, treatment with the DNA damaging agent mitomycin C produced a several fold higher frequency of chromosome breaks in the EMSY overexpressing cells than in the control cells. Overexpression of the 5' fragment o f EMSY did not induce a chromosomal instability phenotype in two immortalized normal ovarian surface epithelial cell lines even after treatment with mitomycin C, suggesting that these cells may not be the correct cell type in which to study EMSY overexpression. EMSY overexpressing breast epithelial cells did not exhibit increased sensitivity to treatment with the DNA damaging agents, doxorubicin and cisplatin, suggesting that EMSY may not play a role in the direct repair of DNA double stranded breaks. In conclusion, these results demonstrate that EMSY amplification is a clinically significant event in breast and ovarian cancer, and elevated levels of EMSY may play a role in sporadic breast carcinogenesis by deregulating protection of genomic stability.

description: Animal husbandry plays a crucial role in the livelihood of farmers and significantly contributes to rural economies. For the proper growth and enhanced productivity of livestock, a balanced and nutritious diet is essential. In today’s context, issues like climate change, land scarcity, and limited availability of traditional fodder have spurred the search for alternative forage sources. In this regard, Ramie grass (Boehmeria nivea) is emerging as a significant plant, recognized for its advanced nutritional qualities as animal feed. Ramie grass, known for its high protein and mineral content, is not only environmentally friendly but also a rapidly growing grass.

description: Efficient digitization is required for quantum simulations of gauge theories. Schemes based on discrete subgroups use fewer qubits at the cost of systematic errors. We systematize this approach by deriving a single plaquette action for approximating general continuous gauge groups through integrating out field fluctuations. This provides insight into the effectiveness of these approximations, and how they could be improved. We accompany the scheme by simulations of pure gauge over the largest discrete subgroup of $SU(3)$ up to the third order.

description: Generally, in any human field, a Smarandache Structure on a set A means a weak structure W on A such that there exists a proper subset B which is embedded with a stronger structure S. By proper subset one understands a set included in A, different from the empty set, from the unit element if any, and from A. These types of structures occur in our everyday's life, thats why we study them in this book. As an example: A non-empty set L is said to form a loop, if on L is defined a binary operation called product, denoted by '.' such that: for all a, b belonging to L we have a . b belonging to L (closure property); there exists an element e belonging to L such that a . e = e . a = a for all a belonging to L (e is the identity element of L); for every ordered pair (a, b) belonging to L x L there exists a unique pair (p, q) in L such that ap = b and qa = b. Whence: A Smarandache Loop (or S-Loop) is a loop L such that a proper subset M of L is a subgroup (with respect to the same induced operation).

description: Brizolis asked the question: does every prime p have a pair (g,h) such that h is a fixed point for the discrete logarithm with base g? The first author previously extended this question to ask about not only fixed points but also two-cycles, and gave heuristics (building on work of Zhang, Cobeli, Zaharescu, Campbell, and Pomerance) for estimating the number of such pairs given certain conditions on g and h. In this paper we extend these heuristics and prove results for some of them, building again on the aforementioned work. We also make some new conjectures and prove some average versions of the results.

description: A model of the Universe as a mixture of a scalar (inflaton or rolling tachyon from the string theory) and a matter field (classical particles) is analyzed. The particles are created at the expense of the gravitational energy through an irreversible process whereas the scalar field is supposed to interact only with itself and to be minimally coupled with the gravitational field. The irreversible processes of particle creation are related to the non-equilibrium pressure within the framework of the extended (causal or second-order) thermodynamic theory. The scalar field (inflaton or tachyon) is described by an exponential potential density added by a parameter which represents its asymptotic value and can be interpreted as the vacuum energy. This model can simulate three phases of the acceleration field of the Universe, namely,(a) an inflationary epoch with a positive acceleration followed by a decrease of the acceleration field towards zero, (b) a past decelerated period where the acceleration field decreases to a maximum negative value followed by an increase towards zero, and (c) a present accelerated epoch. For the energy densities there exist also three distinct epochs which begin with a scalar field dominated period followed by a matter field dominated epoch and coming back to a scalar field dominated phase.

description: Open-ended human learning and information-seeking are increasingly mediated by digital assistants. However, such systems often ignore the user's pre-existing knowledge. Assuming a correlation between engagement and user responses such as "liking" messages or asking followup questions, we design a Wizard-of-Oz dialog task that tests the hypothesis that engagement increases when users are presented with facts related to what they know. Through crowd-sourcing of this experiment, we collect and release 14K dialogs (181K utterances) where users and assistants converse about geographic topics like geopolitical entities and locations. This dataset is annotated with pre-existing user knowledge, message-level dialog acts, grounding to Wikipedia, and user reactions to messages. Responses using a user's prior knowledge increase engagement. We incorporate this knowledge into a multi-task model that reproduces human assistant policies and improves over a BERT content model by 13 mean reciprocal rank points.

title: Long-term patterns of mortality and regeneration in near-natural woodland
Creators: name: Mountford, Edward Peter
Publisher: name: The Open University
Year: 2005

description: 1. Long-term patterns of natural regeneration, growth, mortality and disturbance were recorded in six native lowland woods around Britain, using a series of permanent transects/plots established during the 1950-80s. Records were made including the position and status of trees, shrubs, established seedlings, dead wood and canopy gaps.
2. The stands inherited various original-natural features and grew away from a managed state. Nonetheless, their structure and composition remained heavily influenced by past treatment and non-native species.
3. The natural development of five woodland types and twelve tree and shrub species was reviewed and four general stages of stand development were recognised.
4. The major processes controlling stand development were: (i) exclusion; (ii) damage caused by wind, drought, large herbivores and grey squirrels; and (iii) regeneration and release below part-broken stands and within/around larger canopy gaps.
5. The main structural changes identified during stand development were: (i) an increase in basal area to a maximum of c.30-50m2 ha-1; (ii) a decline in stem density until understorey reinitiation/gap-phase regeneration occurred; (iii) an increase instratification, especially under lighter crowned trees and once reinitiation/regeneration occurred; (iv) a scarcity of canopy gaps until at least 125-150 years growth, after which gap creation tended to be patchy and mainly associated with windstorms and drought,though an extensive blow down was recorded; and (v) a scarcity of dead wood until stands matured and broke-up.
6. Compared to other temperate forests, several distinctive aspects of stand development were recognised, particularly: (i) the role of large herbivores in delaying and altering regeneration; (ii) the importance of debarking by grey squirrels; (iii) the potential for some canopy gaps to fill other than with tree regeneration; (iv) the persistence of the understorey in certain native stand types; and (v) the vulnerability of mature beech stands to sudden and quite extensive collapse.

description: La Hiperostosis Esquelética Idiopática Difusa (DISH), es una patología reumatológica que se identifica por la calcificación y/u osificación del ligamento longitudinal anterior de la columna vertebral, de algunas zonas de inserción y del ligamento interespinoso además de otros tejidos blandos. Su etimología se explica por la acumulación de sales de calcio en ligamentos y tendones, lo que deriva en un endurecimiento y desarrollo de los mismos. Sus manifestaciones más comunes consisten en la formación de osificaciones exuberantes, así como de puentes óseos intervertebrales, y la preservación de espacio intervertebrales. Los objetivos principales del presente trabajo se centran en la identificación de anomalías y rasgos específicos presentes en un individuo procedente del cementerio de Lucena (Córdoba), concretamente el denominado LU-012. La identificación de esta patología en tal individuo permite conocer las características esenciales que la distinguen de otras enfermedades, con el fin de, a través de la realización de un buen diagnóstico diferencial, corregir las valoraciones erróneas de patologías óseas vertebrales similares, tales como la Espondilitis Anquilosante (mal de Bechterew).

description: Immunotherapy, targeting programmed death-1 (PD-1) enhances antitumor T-cell activity in patients with malignancies. Blocking PD-1 or its ligand may lead to fulminant colitis as serious adverse event in these patients. Since little is known of the presence and role of PD-1+T cells in colitis of different etiologies, we determined PD-1+T cells in mucosal specimens of patients with inflammatory bowel disease, infectious colitis (InfC), immunotherapy-related colitis (ImC) and healthy controls (HC). Newly diagnosed patients with ulcerative colitis (UC, n = 73), Crohn’s disease (CD, n = 50), InfC (n = 5), ImC (n = 8) and HC (n = 8) were included. Baseline inflamed colonic biopsies were studied with immunohistochemistry and flowcytometry. Using immunohistochemistry, PD-1 was not present on lymphocytes in the epithelium of all patients, nor in HC. The percentage PD-1+ of all lymphocytes in the lamina propria was 40% in UC, 5% in InfC, 3% in ImC and 0% in HC. Flowcytometry showed significant higher percentages of PD-1+T cells in inflamed biopsy specimens of UC patients (22%) compared to all other groups: CD patients (13%), InfC (12%), ImC (5%) and HC (6%). There are relevant differences in distribution and frequencies of mucosal PD-1+ T-cell subsets in patients with UC, CD, InfC and ImC, supporting the hypothesis that these types of colitis are driven by different immunological pathways. The increased numbers of PD-1+ and PD-L1+ lymphocytes in the colonic mucosa of UC patients suggest that the PD-1/PD-L1 pathway might be more activated in UC than in CD.

description: We consider solitonic solutions of coupled scalar systems, whose Lagrangian has a potential term (quasi-supersymmetric potential) consisting of the square of derivative of a superpotential. The most important feature of such a theory is that among soliton masses there holds a Ritz-like combination rule (e.g. $M_{12}+M_{23}=M_{13}$), instead of the inequality ($M_{12}+M_{23}
