description: Let $K$ be a complete quasivariety of topological inverse Clifford semigroups, containing all topological semilattices. It is shown that the free topological inverse semigroup $F(X,K)$ of $X$ in the class $K$ is an $R^\infty$-manifold if and only if $X$ has no isolated points and $F(X,K)$ is a retract of an $R^\infty$-manifold. We derive from this that for any retract $X$ of an $R^\infty$-manifold the free topological inverse semigroup $F(X,K)$ is an $R^\infty$-manifold if and only if the space $X$ has no isolated points. Also we show that for any homotopically equivalent retracts $X,Y$ of $R^\infty$-manifolds with no isolated points the free topological inverse semigroups $F(X,K)$ and $F(Y,K)$ are homeomorphic. This allows us to construct non-homeomorphic spaces whose free topological inverse semigroups are homeomorphic.

description: Engineering of Sport 15 - Proceedings from the 15th International Conference on the Engineering of Sport (ISEA 2024)
The midsole component of a running shoe is typically made from a polymer foam and the desired properties can be achieved by altering the material compound and topology. The primary function of the midsole is to cushion the impact forces generated as the foot contacts the ground. Impact drop testers are commonly used instruments to assess the cushioning properties of the heel and forefoot regions of running shoes. Understanding how changes in mechanical properties are perceived by users could be beneficial to footwear manufacturers, enabling more targeted product testing. Visual analogue and point scales have been used to investigate user perceptions of shoe properties, however, sensory discrimination tests (e.g., paired comparison tests) have been found to have increased sensitivity. Paired comparison tests showed improved correspondence than scale measures comparing perception ranking to impact test results. A just noticeable difference in max impact shock of 1.4 g was found. The aim of this study was to assess the just noticeable difference in shoe cushioning properties using a sensory discrimination test.

Charmonium from Statistical Hadronization of Heavy Quarks -- a Probe for Deconfinement in the Quark-Gluon Plasma

Year: 2009

description: We review the statistical hadronization picture for charmonium production in ultra-relativistic nuclear collisions. Our starting point is a brief reminder of the status of the thermal model description of hadron production at high energy. Within this framework an excellent account is achieved of all data for hadrons built of (u,d,s) valence quarks using temperature, baryo-chemical potential and volume as thermal parameters. The large charm quark mass brings in a new (non-thermal) scale which is explicitely taken into account by fixing the total number of charm quarks produced in the collision. Emphasis is placed on the description of the physical basis for the resulting statistical hadronization model. We discuss the evidence for statistical hadronization of charmonia by analysis of recent data from the SPS and RHIC accelerators. Furthermore we discuss an extension of this model towards lower beam energies and develop arguments about the prospects to observe medium modifications of open and hidden charm hadrons. With the imminent start of the LHC accelerator at CERN, exciting prospects for charmonium production studies at the very high energy frontier come into reach. We present arguments that, at such energies, charmonium production becomes a fingerprint of deconfinement: even if no charmonia survive in the quark-gluon plasma, statistical hadronization at the QCD phase boundary of the many tens of charm quarks expected in a single central Pb-Pb collision could lead to an enhanced, rather than suppressed production probability when compared to results for nucleon-nucleon reactions scaled by the number of hard collisions in the Pb-Pb system.

description: The emission nebula around the subdwarf B (sdB) star PHL 932 is currently classified as a planetary nebula (PN) in the literature. Based on a large body of multi-wavelength data, both new and previously published, we show here that this low-excitation nebula is in fact a small Stromgren sphere (HII region) in the interstellar medium around this star. We summarise the properties of the nebula and its ionizing star, and discuss its evolutionary status. We find no compelling evidence for close binarity, arguing that PHL 932 is an ordinary sdB star. We also find that the emission nebulae around the hot DO stars PG 0108+101 and PG 0109+111 are also Stromgren spheres in the ISM, and along with PHL 932, are probably associated with the same extensive region of high-latitude molecular gas in Pisces-Pegasus.

description: This thesis presents the design, implementation, and evaluation of a proposed method for stabilizing, or baselining, a subject’s brain activity in preparation for an EEG experiment. The objective is to reduce signal noise and randomness in recorded brain activity by incorporating a brief meditation prior to recording EEG data for a given experiment. This experiment incorporates the use of multiple metrics for measuring and gauging the level of noise and randomness that is present in an EEG signal.

The design of this experiment considers the common challenges with inherent noise and randomness in EEG recordings. Using several methods for classifying the level of noise and randomness, the experiment seeks to provide reliable methods for gauging the short-term lasting effects meditation has on these undesired parameters.

In combination with using the most widely accepted method of meditation relating to EEG research, focused breathing, several analysis methods were used for interpreting the results. Methods such as Independent Component Analysis (ICA), Signal to Noise Ratio (SNR), Sample Entropy (SampEn), Coherence, Phase Synchronization (Phase Sync), and Pearson Correlation were implemented. Additional reference metrics, Power Spectral Density (PSD) and heart rate were also used for supporting data. Detailed results and analysis are presented for the interpretation of the signal noise and randomness gauge metrics. Even with the limitations of the one-time experiment, this thesis does show evidence for the benefits of reduced noise and randomness of EEG recordings after the incorporation of a brief meditation.
The listening eye

Publisher: name: University of British Columbia
Year: 2011

description: This is the sightless cinema. Here sound is both the medium and the message, the process and the product. Modem man is primarily a visually oriented animal. His perception is to a great extent governed by sight— "seeing is believing" —and he tends to translate what he hears into visual terms. But hearing is in itself a kind of seeing: a watchful ear becomes a listening eye as sound yields association and words evoke images. Whales, on the other hand, perceive the world in auditory terms. They translate objects into sound by echo location. The sightless cinema, then, might be considered the theatre of human echo location— a documentation and expression of life in purely aural translation. Words— whether spoken, sung, or read from the page— are the common denominator of man's aural communication. Alone, or combined with sound effects or music, they are capable of evoking and communicating images which are highly visual. Eisenstein’s theory of filmic montage applies here as readily as it does to the cinema of sight. It is the juxtaposition of sounds, the creating of texture within the acoustic space, that makes A + B equal more than the mere sum of the components. The documentaries and songs in this thesis attempt to portray fragments of life aurally by combining words, sounds and music in a way that is palatable to the listening eye.

description: We have quantified collisional losses, decoherence and the collision shift in a one-dimensional optical lattice clock with bosonic 88Sr. The lattice clock is referenced to the highly forbidden transition 1S0 - 3P0 at 698 nm, which becomes weakly allowed due to state mixing in a homogeneous magnetic field. We were able to quantify three decoherence coefficients, which are due to dephasing collisions, inelastic collisions between atoms in the upper and lower clock state, and atoms in the upper clock state only. Based on the measured coefficients, we determine the operation parameters at which a 1D-lattice clock with 88Sr shows no degradation due to collisions on the relative accuracy level of 10-16.

description: We present an analysis of a 72 ks Chandra observation of the double cluster Abell 1644 (z=0.047). The X-ray temperatures indicate the masses are M500=2.6+/-0.4 x10^{14} h^{-1} M_sun for the northern subcluster and M500=3.1+/-0.4 x10^{14} h^{-1} M_sun for the southern, main cluster. We identify a sharp edge in the radial X-ray surface brightness of the main cluster, which we find to be a cold front, with a jump in temperature of a factor of ~3. This edge possesses a spiral morphology characteristic of core gas sloshing around the cluster potential minimum. We present observational evidence, supported by hydrodynamic simulations, that the northern subcluster is the object which initiated the core gas sloshing in the main cluster at least 700 Myr ago. We discuss reheating of the main cluster's core gas via two mechanisms brought about by the sloshing gas: first, the release of gravitational potential energy gained by the core's displacement from the potential minimum, and second, a dredging inwards of the outer, higher entropy cluster gas along finger-shaped streams. We find the available gravitational potential energy is small compared to the energy released by the cooling gas in the core.

description: The field of population genetics attempts to advance our understanding of evolutionary processes. It has applications, for example, in medical research, wildlife conservation, and - in conjunction with recent advances in ancient DNA sequencing technology - studying human migration patterns over the past few thousand years. The basic toolbox of population genetics includes genealogical trees, which describe the shared evolutionary history among individuals of the same species. They are calculated on the basis of genetic variations. However, in recombining organisms, a single tree is insufficient to describe the evolutionary history of the whole genome. Instead, a collection of correlated trees can be used, where each describes the evolutionary history of a consecutive region of the genome. The current corresponding state of-the-art data structure, tree sequences, compresses these genealogical trees via edit operations when moving from one tree to the next along the genome instead of storing the full, often redundant, description for each tree. We propose a new data structure, genealogical forests, which compresses the set of genealogical trees into a DAG. In this DAG identical subtrees that are shared across the input trees are encoded only once, thereby allowing for straight-forward memoization of intermediate results. Additionally, we provide a C++ implementation of our proposed data structure, called gfkit, which is 2.1 to 11.2 (median 4.0) times faster than the state-of-the-art tool on empirical and simulated datasets at computing important population genetics statistics such as the Allele Frequency Spectrum, Patterson’s f, the Fixation Index, Tajima’s D, pairwise Lowest Common Ancestors, and others. On Lowest Common Ancestor queries with more than two samples as input, gfkit scales asymptotically better than the state-of-the-art, and is thus up to 990 times faster. In conclusion, our proposed data structure compresses genealogical trees by storing shared subtrees only once, thereby enabling straight-forward memoization of intermediate results, yielding a substantial runtime reduction and a potentially more intuitive data representation over the state-of-the-art. Our improvements will boost the development of novel analyses and models in the field of population genetics and increases scalability to ever-growing genomic datasets.

description: In 1943, the Alex and Esther Bernal of Fullerton, California became the first known Mexican American family in the United States to win in court against racially restrictive housing covenants. After setting legal precedent, the Bernals’ story faded from the public memory for nearly seventy years. As a case study, the Bernals’ experience with racialized housing discrimination provides us with insight into the complicated relationship between race, space, and public memory. In this thesis, I situate the Bernals’ story within the broader context of racialized space during the early- to mid-twentieth century. I examine how mechanisms such as labor, immigration policy, and residential settlement during World War II contributed to racialized perceptions of Mexican American identity and often led to exclusion from the dominant white society. I unpack the underlying politics in Bernals’ landmark trial and analyze the complex role that race played in their winning legal strategy, which argued that Mexican Americans are Caucasian and racial restrictions against them are unconstitutional. I examine how the Bernals’ story was reintroduced into the public discourse and highlight the silences in the popular version of the Bernals’ narrative which primarily celebrates this history as a complete victory. However, I maintain that the Bernals’ victory was limited, as the outcome of Doss v. Bernal did not bring an immediate end tosegregation. Ultimately, I argue that the popular, oversimplified narrative of the Bernals’ story challenges and simultaneously runs the risk of reinforcing racial inequality by failing to confront it. Furthermore, I argue that telling a fuller version of the Bernals’ story is beneficial as it provides us with a model of how resistance against racial oppression is enacted.

The dynamics of carrier cooling in GaAs and impact ionization in InSb were monitored using THz-pump/THz probe spectroscopy which provides both sub-bandgap excitation and probing, eliminating any direct optical electron-hole generation that complicates the evaluation of results in optical pump/THz probe experiments.

What is it like to be a vocational student today? A phenomenological study of the vocational student experience in school sixth form education

Publisher: name: Anglia Ruskin Research Online (ARRO)
Year: 2024

description: Vocational education has a long history within the UK education system. Despite the various descriptions and guises, it remains an important part of the education to work transition. Within the traditionally academic setting of school sixth form education, vocational education is a relatively new phenomenon and therefore understandings of it are underdeveloped. A gap in knowledge identified through the study of relevant literature inspires this research to gain insights into the lived experience of the school sixth form vocational student.An Interpretive Phenomenological Interpretation (IPA) approach was adopted to develop understandings of the meanings participants gave to their lived experiences of school sixth form vocational education. A reflexive researcher stance enabled close consideration of how data was gathered, enabling participants to contribute on their own terms in a natural environment. A novel data collection method was developed which utilised a self-governing focus group whereby participants contributed in a data collection space distanced from the interviewer. A methodologically congruent process of analysing focus group data was also developed and refined which attended to the individual account while acknowledging group social interactions.The participants of this research experienced a greater degree of uncertainty in their vocational studies than in their academic studies. The uncertainty led to heightened experiences of flux, risk and compromise within their school lives. Vocational education within their sixth form setting provided nuanced opportunities to explore career options, ambitions and interests but required increased skills in tenacity for participants to navigate successfully to their career goals. Experiences of flux, risk and compromise drove participants to advance their wider skills beyond that those that are taught in the classroom. While participants negotiated the complex world of vocational education, they formed a new, tenacious identity as the school sixth form vocational student.New understandings of vocational education in sixth form settings show there is a conflict in rhetoric between academically experienced teachers as guides and other influences such as peers, media and university which must be resolved by the participants themselves. Opportunities now arise in sixth forms to challenge current understandings and practice thereby facilitating improvements with positive outcomes for all stakeholders.

description: In Bounded Model Checking both the system model and the checked property are translated into a Boolean formula to be analyzed by a SAT-solver. We introduce a new encoding technique which is particularly optimized for managing quantitative future and past metric temporal operators, typically found in properties of hard real time systems. The encoding is simple and intuitive in principle, but it is made more complex by the presence, typical of the Bounded Model Checking technique, of backward and forward loops used to represent an ultimately periodic infinite domain by a finite structure. We report and comment on the new encoding technique and on an extensive set of experiments carried out to assess its feasibility and effectiveness.

The project asked anyone with a personal, professional or voluntary interest in archaeology to get involved, and help highlight the reasons why archaeology is vital to protect the past and inform our futures. The resulting Day of Archaeology project archive demonstrates the wide variety of work the archaeological profession undertakes day-to-day across the globe, and helps to raise public awareness of the relevance and importance of archaeology to the modern world.
The first ever Day of Archaeology was held in 2011 and, since then, the project had thousands of archaeologists take part in the event, from those working in the field through to specialists working in laboratories and behind computers. The last Day of Archaeology was on Friday 28th July 2017.

description: It is shown that each pseudonorm defined on a subgroup $H$ of an abelian group $G$ can be extended to a pseudonorm on $G$ such that the densities of the obtained pseudometrizable topological groups coincide. We derive from this that any Hausdorff $ω$-bounded group topology on $H$ can be extended to a Hausdorff $ω$-bounded group topology on $G$. In its turn this result implies that each separable metrizable abelian group $H$ is a subgroup of a separable metrizable divisible group $G$. This result essentially relies on the Axiom of Choice and is not true under the Axiom of Determinacy (which contradicts to the Axiom of Choice but implies the Countable Axiom of Choice).

Disordered topological quantum critical points in three-dimensional systems

description: Generic non-magnetic disorder effects onto those topological quantum critical points (TQCP), which intervene the three-dimensional topological insulator and an ordinary insulator, are investigated. We first show that, in such 3-d TQCP, any backward scattering process mediated by the chemical-potential-type impurity is always canceled by its time-reversal (T-reversal) counter-process, because of the non-trivial Berry phase supported by these two processes in the momentum space. However, this cancellation can be generalized into only those backward scattering processes which conserve a certain internal degree of freedom, i.e. the parity density, while the `absolute' stability of the TQCP against any non-magnetic disorders is required by the bulk-edge correspondence. Motivated by this, we further derive the self-consistent-Born phase diagram in the presence of generic non-magnetic disorder potentials and argue the behaviour of the quantum conductivity correction in such cases. The distinction and similarity between the case with only the chemical-potential-type disorder and that with the generic non-magnetic disorders are finally summarized.

Cosmic ray observations at high zenith angles
Creators: name: Vrana, A
Publisher: name: University Of Tasmania
Year: 2023

description: The thesis is the description of the design and construction of a high zenith angle telescope for the Mawson observatory, together with some discussion of results obtained. Because the new Mawson observatory installed in 1972 is a logical extension complementing the high zenith angle experiment, it was felt that inclusion of a brief description of the new observatory complex would not be out of place. l joined the Australian National Antarctic Research Expedition in 1964 as an expedition physicist. During my stay at Mawson in 1965 I became aware of the shortcomings of mains operated electronic equipment at remote stations and designed some battery operated solid state circuits to replace the former circuitry. Upon my return from Mawson I was commissioned to finalise the design of the transistorised circuitry and develop modular circuit units for the use with counter telescopes. In 1966 a joint project was proposed by the Antarctic Division and the University of Tasmania for a high zenith angle ground based experiment. Given the basic requirements for the desired geometry I was to undertake the design, construction and installation of the new telescopes at Mawson. During the course of the work I realized that for a successful design an understanding of the principles of cosmic ray recording was necessary. Whilst the design of the experiment rested primarily on Dr. R.M. Jacklyn, I undertook the initial investigation of the air shower component influencing the observed intensity under the guidance of Dr. A.G. Fenton and Dr. R.M. Jacklyn. I sailed for Mawson in early 1968 to install and supervise the performance of the new telescope during the first year of operation. After my return to Hobart I carried out further tests regarding the air shower component as described in sec. 3.4, based on the original idea of Mr. G.C. Cooper, the Mawson physicist in 1969. In 1970 the Antarctic Division undertook to establish an underground observatory based on the proposal of Dr. R.M. Jacklyn. The design of the experiment originated from Dr. R.M. Jacklyn based on the detailed calculations of asymptotic directions by Dr. D.J. Cooke and I had the responsibility of the design and construction of the detectors, electronic circuitry, specification of the new observatory building and selection of the site for the observatory. In late 1971 I again sailed for Mawson to supervise the installation of the new observatory and initiate the operation of the equipment. The thesis is also aimed to give assistance to the operator of the observatory in the maintenance of the equipment; therefore the function of some of the electronics are described in more detail than otherwise might seem necessary. Although some of the electronic circuits appear to be cumbersome and unnecessarily complicated at today's standard of component development, at the time of design they represented the optimum in cost, complexity and component availability.

In virtually every sport, the interaction between footwear and the ground or playing surface is a pivotal factor influencing performance. Insufficient traction between the two results in the foot slipping. This can be deliberate, as for example tennis slides on clay, but can also lead to an increased risk of injuries, such as when hiking on loose rocks, or playing tennis on a wet court. Involuntary slips also constitute a direct loss of energy, which diminishes performance. For example, a slipping foot in wrestling means less force is transferred through the lower body. Slipping hinders rapid changes in direction in sports such as football. For runners, it has been proposed that small, imperceptible slips called microslips could affect performance. Studies of slips pertaining to occupational injuries are numerous and have estimated the limits of microslips to be 3cm, while macroslips between 3-10 cm lead to perturbations of balance and greater than 10 cm likely lead to a fall. Equivalent measures were not found within the context of sports science. However, traction between footwear and ground is often assessed in a laboratory setting, using 6-axis force plates. Athletes have to first recreate as best as they can sport-specific movements, while aligning their movements to land within the limits of the force plates. A wearable slip measurement system could be used to detect when traction is insufficient to prevent slippage. These measures, from real sports scenarios, would improve realism and diversity of movements, and could help improve footwear and playing surfaces and monitor player performances and risks of injury.
