description: We provide conservative bounds on the dark matter cross-section and lifetime from final state radiation produced by annihilation or decay into charged leptons, either directly or via an intermediate particle $ϕ$. Our analysis utilizes the experimental gamma-ray flux upper limits from four Milky Way dwarf satellites: HESS observations of Sagittarius and VERITAS observations of Draco, Ursa Minor, and Willman 1. Using 90% confidence level lower limits on the integrals over the dark matter distributions, we find that these constraints are largely unable to rule out dark matter annihilations or decays as an explanation of the PAMELA and ATIC/PPB-BETS excesses. However, if there is an additional Sommerfeld enhancement in dwarfs, which have a velocity dispersion ~10 to 20 times lower than that of the local Galactic halo, then the cross-sections for dark matter annihilating through $ϕ$'s required to explain the excesses are very close to the cross-section upper bounds from Willman 1. Dark matter annihilation directly into $τ$'s is also marginally ruled out by Willman 1 as an explanation of the excesses, and the required cross-section is only a factor of a few below the upper bound from Draco. Finally, we make predictions for the gamma-ray flux expected from the dwarf galaxy Segue 1 for the Fermi Gamma-ray Space Telescope. We find that for a sizeable fraction of the parameter space in which dark matter annihilation into charged leptons explains the PAMELA excess, Fermi has good prospects for detecting a gamma-ray signal from Segue 1 after one year of observation.

The effect of acute alcohol intoxication on the ability to detect sarcasm, and metacognitive judgements of sarcasm detection ability
Creators: name: Turner, Jason
Publisher: name: University Of Tasmania
Year: 2023

description: Acute excessive alcohol-intoxication has been increasingly linked to negative social behaviours such as increased aggression, one punch assaults, and partner-related violence, however the underlying mechanisms underpinning these processes are not yet understood. This study aimed to establish whether alcohol intoxication impairs the ability to detect and differentiate sarcasm, a type of theory of mind concerned with the ability to infer the intentions, beliefs, and perspectives of others. An additional aim of the study was to examine if metacognitive judgements (insight) of sarcasm detection ability is also impaired following alcohol-intoxication. Following quasi-random allocation counterbalancing for gender, 47 participants were administered either an alcohol (Mage = 23.31, SD = 4.33) or placebo (Mage = 22.71, SD = 3.23) beverage. Theory of Mind abilities were assessed using The Awareness of Social Inference Test ‚Äö- Short Version (TASIT-S). Metacognitive performance was measured by obtaining confidence ratings of between zero and 100 percent for each sarcasm detection item. While no overall impairment in sarcasm detection ability was found for alcohol-intoxicated individuals, intoxicated individuals were poorer at comprehending how an actor is feeling when the actor is being sincere and telling lies. Intoxicated individuals also demonstrated impaired insight and over-confidence in metacognitive judgements. These findings provide new insight into the possible underlying mechanisms of acute alcohol-intoxication and negative social behaviours, and have important policy implications.

description: Light carrying an orbital angular momentum (OAM) displays an optical phase front rotating in space and time and a vanishing intensity, a so-called vortex, in the center. Beyond continuous-wave vortex beams, optical pulses with a finite OAM are important for many areas of science and technology, ranging from the selective manipulation and excitation of matter to telecommunications. Generation of vortex pulses with a duration of few optical cycles requires new methods for characterising their coherence properties in space and time. Here we report a novel approach for flexibly shaping and characterising few-cycle vortex pulses of tunable topological charge with two sequentially arranged spatial light modulators. The reconfigurable optical arrangement combines interferometry, wavefront sensing, time-of-flight and nonlinear correlation techniques in a very compact setup, providing complete spatiooral coherence maps at minimum pulse distortions. Sub-7â €...fs pulses carrying different optical angular momenta are generated in single and multichannel geometries and characterised in comparison to zero-order Laguerre-Gaussian beams. To the best of our knowledge, this represents the shortest pulse durations reported for direct vortex shaping and detection with spatial light modulators. This access to space-time coupling effects with sub-femtosecond time resolution opens new prospects for tailored twisted light transients of extremely short duration.

В соответст-вии с действующими нормативными документами контроль работы систем протекторной защиты корпу-сов рыбопромысловых судов осуществляется в ручном режиме, однако данный вид контроля отличается высокой трудоемкостью и требует подготовки квалифицированных операторов систем электрохимической защиты от коррозии. Необходимо разработать автоматизированную систему контроля протекторной за-щиты корпусов рыбопромысловых судов (АСКПЗКС). В результате проведенных нами лабораторных ис-следований была оценена надежность элементной базы АСКПЗКС и метрологические характеристики результатов контрольных измерений. Затем выполняли натурные коррозионные исследования на судне ПЖС-219 (морской рыбный порт г. Петропавловска-Камчатского). Установлено, что достоверность ре-зультатов контроля протекторных систем защиты от коррозии корпусов судов возрастает при использова-нии автоматизированной системы контроля протекторной защиты.

description: The surface-enhanced Raman scattering (SERS) spectra of thioanisole are experimentally investigated in an electrochemical environment in this study. Two Raman peaks, which depend strongly not only on electric potential but also on the local surface plasmon resonances (LSPR), have been observed. Theoretical calculations reveal that thioanisole is first dissociated from thiophenol via the S-CH3 bond; plasmons then drive the dimerisation of thiophenol via the S-S bond, which is strongly potential dependent. One Raman peak corresponds to the S-S vibrational mode of the thiophenol dimer, and the other corresponds to the asymmetric C-C stretching modes of the benzenyl of the thiophenol dimer. The potential-dependent two Raman modes is the potential-dependent dimerisation dynamics of thiophenol via the S-S bond. Our experimental findings provide insight into the structural elucidation of adsorbed molecules and molecular surface reaction dynamics.

description: We prove that for any euclidean ring R and n at least 6, Gamma=SL_n(R) has no unbounded quasi-homomorphisms. From Bavard's duality theorem, this means that the stable commutator length vanishes on Gamma. The result is particularly interesting for R = F[x] for a certain field F (such as the field C of complex numbers, because in this case the commutator length on Gamma is known to be unbounded. This answers a question of M. Abért and N. Monod for n at least 6.

Представлены результаты визуальных наблюдений за поведением морских птиц, их распределение при промысловых операциях судна, анализ эффективности применения одиночных стримерных линий на донном ярусном промысле для отпугивания морских птиц и сокращения их уровня смертности, анализ данных по смертности морских птиц. В зависимости от района и сезона промысла вокруг судов отмечалось 4–8 видов птиц. Преобладали глупыш (темной и светлой морфы), тихоокеанская и серокрылая чайки, бургомистр, моевка, темноспин-ный и белоспинный альбатросы. Проведенные исследования подтвердили, что для решения проблемы «морские птицы – ярусное рыболовство» могут с успехом использоваться одиночные стримерные линии. В плане снижения потерь наживы и уровня смертности птиц эти результаты, наряду с данными по частоте попадания птиц на крючки, показывают довольно высокую эффективность одиночных стримерных линий.

description: Two complementary techniques are developed for obtaining the asymptotic form of gravitational-wave data at large radii from numerical simulations, in the form of easily implemented algorithms. It is shown that, without extrapolation, near-field effects produce errors in extracted waveforms that can significantly affect LIGO data analysis. The extrapolation techniques are discussed in the context of Newman--Penrose data applied to extrapolation of waveforms from an equal-mass, nonspinning black-hole binary simulation. The results of the two methods are shown to agree within error estimates. The various benefits and deficiencies of the methods are discussed.

Гранулы корма, вымоченные в водном экстракте мотыля, имели индифферентный вкус, т. е. их потребление достоверно не отличалось от потреб-ления сухих гранул корма.
Syn-depositional fault controls on the Hellyer Volcanic-hosted massive sulphide deposit
Creators: name: Downs, RC
Publisher: name: University Of Tasmania
Year: 2023

description: Hellyer is a late-Middle Cambrian volcanic-hosted massive sulphide deposit, situated within the Mount Read Volcanics of western Tasmania. The effects of post-depositional folding and wrench faulting have been removed from the deposit to produce an interpreted Cambrian seafloor topographic contour map. This map reveals that the massive sulphide orebody formed within a north-south striking, fault controlled basin. Intersections of active, syn-depositional faults appear to have channelled hydrothermal fluids, and hence, controlled the location of massive sulphide formation. The most intense hydrothermal fluid flux was focussed on the intersection of three major structural elements:- i) north-south striking basin bounding faults, ii) a northeast striking fault, and iii) a northwest striking ridge. Metal-rich stringer veins within the footwall indicate that the orebody formed during the period of time when northeast striking faults were actively dilating due to northwest directed extension. During the waning stages of the hydrothermal system, basaltic magma rose up through a similar set of fissures and erupted onto the seafloor, burying and preserving the deposit.

description: We consider the dynamics of semi-hyperbolic semigroups generated by finitely many rational maps on the Riemann sphere. Assuming that the nice open set condition holds it is proved that there exists a geometric measure on the Julia set with exponent $h$ equal to the Hausdorff dimension of the Julia set. Both $h$-dimensional Hausdorff and packing measures are finite and positive on the Julia set and are mutually equivalent with Radon-Nikodym derivatives uniformly separated from zero and infinity. All three fractal dimensions, Hausdorff, packing and box counting are equal. It is also proved that for the canonically associated skew-product map there exists a unique $h$-conformal measure. Furthermore, it is shown that this conformal measure admits a unique Borel probability absolutely continuous invariant (under the skew-product map) measure. In fact these two measures are equivalent, and the invariant measure is metrically exact, hence ergodic.

description: (Abridged) Bright-rimmed clouds (BRCs) are isolated molecular clouds located on the edges of evolved HII regions where star formation is thought may have been triggered. In this paper we investigate the current level of star formation within a sample of BRCs and evaluate to what extent star formation may have been induced. We present the results of a programme of position-switched CO observations towards 45 southern BRCs. The 12CO, 13CO and C18O (J=1-0) were simultaneously observed using the 22m Mopra telescope. We complement these observations with archival mid-IR submm and radio data. Analysis of the CO, mid-IR and radio data result in the clouds being divided into three distinct groups. We refer to these groups as spontaneous, triggered, and zapped clouds, respectively. Comparing the physical parameters of spontaneous and triggered samples we find striking differences in luminosity, surface temperature and column density with all three quantities significantly enhanced for the clouds considered to have been triggered. Furthermore, we find strong evidence for star formation within the triggered sample by way of methanol and H_2O masers, embedded mid-IR point sources and CO wings, however, we find evidence of ongoing star formation within only two of the spontaneous sample. We have used CO, mid-IR and radio data to identify 24 of the 45 southern BRCs that are undergoing a strong interaction with their HII region. We can therefore exclude ~50% from future studies. 14 of the 24 interacting BRCs are found to be associated with embedded mid-IR point sources and we find strong evidence of that these clouds are forming stars. The absence of mid-infrared sources towards the remaining ten clouds leads us to conclude that these represent an earlier evolutionary stage of star formation.

The magnetic field geometries of these stars, investigated with spectropolarimetric time series, can likely be described by centred dipoles with polar magnetic field strengths of several hundred Gauss. A number of Herbig Ae/Be stars with detected magnetic fields have recently been observed with X-shooter in the visible and the near-IR, as well as with the high-resolution near-IR spectrograph CRIRES. These observations are of great importance to understand the relation between the magnetic field topology and the physics of the accretion flow and the accretion disk gas emission.

description: Scattering theory is employed to derive a Landauer-type formula for the spin and the charge currents, through a finite region where spin-orbit interactions are effective. It is shown that the transmission matrix yields the spatial direction and the magnitude of the spin polarization. This formula is used to study the currents through a tubular two-dimensional electron gas. In this cylindrical geometry, which may be realized in experiment, the transverse conduction channels are not mixed (provided that the spin-orbit coupling is uniform). It is then found that for modest boundary scattering, each step in the quantized conductance is split into two, and the new steps have a non-zero spin conductance, with the spin polarization perpendicular to the direction of the current.

Short-Term H-alpha Variability in M Dwarfs

description: We spectroscopically study the variability of H-alpha emission in mid- to late-M dwarfs on timescales of ~0.1-1 hr as a proxy for magnetic variability. About 80% of our sample exhibits statistically significant variability on the full range of timescales probed by the observations, and with amplitude ratios in the range of ~1.2-4. No events with an order of magnitude increase in H-alpha luminosity were detected, indicating that their rate is < 0.05 /hr (95% confidence level). We find a clear increase in variability with later spectral type, despite an overall decrease in H-alpha "activity" (i.e., L_{H-alpha}/L_{bol}). For the ensemble of H-alpha variability events, we find a nearly order of magnitude increase in the number of events from timescales of about 10 to 30 min, followed by a roughly uniform distribution at longer durations. The event amplitudes follow an exponential distribution with a characteristic scale of Max(EW)/Min(EW)}-1 ~ 0.7. This distribution predicts a low rate of ~ 10^{-6} /hr for events with (Max(EW)/Min(EW) > 10, but serendipitous detections of such events in the past suggests that they represent a different distribution. Finally, we find a possible decline in the amplitude of events with durations of > 0.5 hr, which may point to a typical energy release in H-alpha events for each spectral type (E_{H-alpha} ~ L_{H-alpha} x t ~ const). Longer observations of individual active objects are required to further investigate this possibility. Similarly, a larger sample may shed light on whether H-alpha variability correlates with properties such as age or rotation velocity.

They are unique examples of feather art (Ars Plumaria). The study focuses on a material analysis and the investigation of the manufacturing techniques of both shields. Amongst others, the correct orientation, the way the shields were used and their dating is clarified. In addition, their collection and exhibition history is reconstructed and a temporal assessment of their previous restorations is carried out. The results form the basis for comparative studies with the few other extant old-Mexican feather objects. A concept was developed for the museum to preserve the feather shields for future generations.

description: The time evolution of a system where a uniform and classical SU(3) color electric field and quantum fields of quarks are dynamically coupled with each other is studied focusing on non-perturbative pair creation and its back reaction. We characterize the color direction of the electric field in a gauge invariant way, and investigate its dependence. Momentum distributions of created quarks show plasma oscillation as well as quantum effects such as the Pauli blocking and interference. Pressure of the system is also calculated, and we show that pair creation moderates degree of anisotropy of pressure. Furthermore, enhancement of pair creation and induction of chiral charge under a color magnetic field which is parallel to the electric field are discussed.

description: Between 1380 and 1422, in the reign of the mad king Charles VI, France suffered rebellion and the civil wars of Armagnacs and Burgundians, quite apart from the disastrous depredations of the English from 1415 onwards. After 1422 England had a mad king too, Henry VI, founder of Eton College; she experienced her own civil wars, the Wars of the Roses, in the middle years of the fifteenth century.

description: The time-dependent variational approach to the pure Yang-Mills gauge theory, especially a color su(3) gauge theory, is formulated in the functional Schroedinger picture with a Gaussian wave functional approximation. The equations of motion for the quantum gauge fields are formulated in the Liouville-von Neumann form. This variational approach is applied in order to derive the transport coefficients, such as the shear viscosity, for the pure gluonic matter by using the linear response theory. As a result, the contribution to the shear viscosity from the quantum gluons is zero up to the lowest order of the coupling g in the quantum gluonic matter.

Control of the function of the heart in teleost fish

Publisher: name: University of British Columbia

description: The purpose of this study was to elucidate some of the mechanisms involved in the control of the function of the fish heart. In vitro experiments were conducted to determine the effect of varying input pressure, temperature, and epinephrine concentration on the isolated, perfused, trout heart. In vivo experiments were conducted with chronically implanted flow probes to determine the effect of increased blood epinephrine levels on the activity of the heart of the lingcod. Five variables were measured to describe the activity of the isolated trout heart: rate, stroke volume, cardiac output, stroke work, and heart work per minute. Heart function curves were constructed showing the relationship between each of these variables and the input pressure at two levels of epinephrine, 0.1 ug/ml and 0.01 ug/ml, and at two temperatures, 6°C and 15°C. The isolated trout heart obeyed Starling's law, since the stroke work increased as the filling pressure, and thus the end diastolic fiber length, increased. Increased filling pressure also caused the heart rate to increase, probably due to a direct effect of pressure on the pacemaker cells. Increased temperature produced an increase in rate, which in turn decreased the filling time available between beats and so decreased the stroke volume. Cardiac output was not greatly affected by temperature changes. Low temperature appeared to have a direct inotropic effect on the heart as well; that is, greater stroke work was produced from a given end diastolic volume at low temperatures. Epinephrine had a pronounced inotropic effect at 15°C. The stroke volume, stroke work, cardiac output, and heart work per minute all increased with high epinephrine. The rate decreased, probably because the systolic emptying was so much more complete that a greater time interval between beats was needed to fill the heart. At 6°C the inotropic effect of low temperature masked the inotropic effect of epinephrine, so that high epinephrine produced no change in stroke work or stroke volume. A positive chronotropic effect was pronounced at this temperature. The cardiac output and heart work per minute increased with epinephrine as a result. The adrenergic receptors mediating the responses of the heart to epinephrine were of the β-type only. The responses were blocked by Inderal, a β-receptor blocking agent, but were unaffected by phenoxybenzamine, an ⍺-receptor blocking agent. Increased levels of epinephrine in the blood of the lingcod at 10° - 12°C produced an increase in the mean blood flow in the ventral aorta. The heart rate remained constant, thus the changes in mean blood flow were due to changes in stroke volume. These stroke volume changes could be produced by epinephrine acting on the heart directly via β-receptors in the myocardium or indirectly via changes produced in the rest of the circulatory system.

description: We present an exploratory study in the context of digital film analysis inspecting and comparing five canonical movies by applying methods of computer vision. We extract one frame per second of each movie which we regard as our sample. As computer vision methods we explore image-based object detection, emotion recognition, gender and age detection with state-of-the-art models. We were able to identify significant differences between the movies for all methods. We present our results and discuss the limitations and benefits of each method. We close by formulating future research questions we plan to answer by applying and optimizing the methods.
Classical phases and quantum angles in the description of interfering Bose-Einstein condensates

description: The interference of two Bose-Einstein condensates, initially in Fock states, can be described in terms of their relative phase, treated as a random unknown variable. This phase can be understood, either as emerging from the measurements, or preexisting to them; in the latter case, the originating states could be phase states with unknown phases, so that an average over all their possible values is taken. Both points of view lead to a description of probabilities of results of experiments in terms of a phase angle, which plays the role of a classical variable. Nevertheless, in some situations, this description is not sufficient: another variable, which we call the "quantum angle", emerges from the theory. This article studies various manifestations of the quantum angle. We first introduce the quantum angle by expressing two Fock states crossing a beam splitter in terms of phase states, and relate the quantum angle to off-diagonal matrix elements in the phase representation. Then we consider an experiment with two beam splitters, where two experimenters make dichotomic measurements with two interferometers and detectors that are far apart; the results lead to violations of the Bell-Clauser-Horne-Shimony-Holt inequality (valid for local-realistic theories, including classical descriptions of the phase). Finally, we discuss an experiment where particles from each of two sources are either deviated via a beam splitter to a side collector or proceed to the point of interference. For a given interference result, we find "population oscillations" in the distributions of the deviated particles, which are entirely controlled by the quantum angle. Various versions of population oscillation experiments are discussed, with two or three independent condensates.

description: The electronic properties and growth morphology of Si(111)/ZnS heterostructure modified by a GaSe van der Waals termination layer, which provides a chemical and an electronic passivation of the Si(111)‐surface is investigated by surface sensitive methods (STM, LEED and SXPS). The van der Waals termination layer suppresses the Si‐S interface reaction, which is observed for non terminated substrates. The interface electronic properties are nearly unchanged, but the morphology of the growing ZnS‐film is dramatically changed. With the passivation layer ZnS grows as orientated pyramides with a (111) base area surface orientaion and (100)‐facets. The sticking coefficient is reduced by a factor of ≈10 compared to bare Si(111), where ZnS grows as an untextured polycrystalline layer.
Sibling rivalry: the India-Australia relationship, 1858-1901
Creators: name: Davis, AE
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis examines the relationship between India and Australia between 1858 and 1901. It draws upon a recent reinterpretation of India's role in the British empire that views it as a power centre. This approach is applied to an examination of the India-Australia relationship to consider how the Indian government and the Australian colonial governments communicated with and acted towards one another. This adds to our understanding of the workings of the British empire, India's role within it and shows Australia's imperial connections to be more complicated than a simple connection with London. Starting with the Indian Rebellion and the transfer of power from the East India Company to the Crown and ending with Australia's partial break with empire, Federation in 1901, this study will discuss a period in which the relationship has received only very limited attention. India's role in the empire was expanding and the administration in both colonies was stable. Material from around Australia is used, including parliamentary papers from New South Wales, Queensland, Tasmania, South Australia and Victoria, and archival material from South Australia and Tasmania. Four chapters focus on separate thematic issues that defined the India-Australia relationship: administrative cooperation, trade, military issues and Indian indentured labour. Previously unknown and unexamined ways in which India and Australia cooperated will be examined. We can conclude from the discussion of administrative cooperation that the relationship between India and Australia was deeper than has previously been acknowledged. The following three chapters continue with this argument, and reveal more details and nuances in the nature of the relationship. The manner of the relationship was extremely friendly ‚Äö- with symbolic gestures on both sides and extremely respectful dialogue. However, it also shows the relationship, as is implied by the conception of India as a major power centre, to be asymmetrical. When it was in her own best interests, India was willing and able to exert its will over Australia. The responses of the Australian colonies to India's ascendancy varied over time and between colonies.

description: В 2010–2019 гг. методом биотестирования исследована токсичность донных отложений Баренцева моря для личинок жаброногого рачка Artemia salina L. Изучалось воздействие водных вытяжек донных отложений на выживаемость рачков. По данным экспериментов, на большей части изученной акватории Баренцева моря донные отложения нетоксичны. Токсичные для личинок A. salina пробы донных отложений зарегистрирова-ли в Центральном, Норвежском, Демидовском, Западно-Новоземельском, Южно-Новоземельском и Коль-ском желобах, на Мурманской, Финмаркенской и Северо-Канинской банках, Мурманском мелководье и в прибрежье на участке от Мотовского залива до о. Кильдин. Среди токсичных донных отложений преоб-ладали слаботоксичные. Результаты биотестирования согласуются с опубликованными данными химико-аналитических исследований. В ряде экспериментов токсичность для личинок A. salina более разбавленных водных вытяжек донных отложений превышала токсичность концентрированных. Водные вытяжки донных отложений оказывали стимулирующее воздействие на рост личинок A. salina.
