description: Tasks in psychophysical tests can at times be repetitive and cause individuals to lose engagement during the test. To facilitate engagement, we propose the use of a humanoid NAO robot, named Sam, as an alternative interface for conducting psychophysical tests. Specifically, we aim to evaluate the performance of Sam as an auditory testing interface, given its potential limitations and technical differences, in comparison to the current laptop interface. We examine the results and durations of two voice perception tests, voice cue sensitivity and voice gender categorisation, obtained from both the conventionally used laptop interface and Sam. Both tests investigate the perception and use of two speaker-specific voice cues, fundamental frequency (F0) and vocal tract length (VTL), important for characterising voice gender. Responses are logged on the laptop using a connected mouse, and on Sam using the tactile sensors. Comparison of test results from both interfaces shows functional similarity between the interfaces and replicates findings from previous studies with similar tests. Comparison of test durations shows longer testing times with Sam, primarily due to longer processing times in comparison to the laptop, as well as other design limitations due to the implementation of the test on the robot. Despite the inherent constraints of the NAO robot, such as in sound quality, relatively long processing and testing times, and different methods of response logging, the NAO interface appears to facilitate collecting similar data to the current laptop interface, confirming its potential as an alternative psychophysical test interface for auditory perception tests.

description: We study an inflation model that inflaton field is non-minimally coupled to the induced scalar curvature on the Randall-Sundrum (RS) II brane. We investigate the effects of the non-minimal coupling on the inflationary dynamics of this braneworld model. Our study shows that the number of e-folds decreases by increasing the value of the non-minimal coupling. We compare our model parameters with the minimal case and also with recent observational data. In comparison with recent observation, we obtain a constraint on the values that the non-minimal coupling attains.

description: The present paper proves that a Sleptsov net (SN) is Turing-complete, that considerably improves, with a brief construct, the previous result that a strong SN is Turing-complete. Remind that, unlike Petri nets, an SN always fires enabled transitions at their maximal firing multiplicity, as a single step, leaving for a nondeterministic choice of which fireable transitions to fire. A strong SN restricts nondeterministic choice to firing only the transitions having the highest firing multiplicity.

description: Ideological echo chambers on digital media platforms have been the subject of extensive research by computational social scientists. Current debates focus on the role of user choice and algorithmic recommendation feeds in creating these echo chambers. In this thesis, I argue that content creators can work to create echo chambers through collaborations with other ideologically aligned creators. Adopting a Gramscian theoretical framework, I argue that these homophilic collaborations are tools of hegemonic struggle, analogous to the “wars of position” described by the late political theorist Antonio Gramsci. To validate my claims, I perform a social network analysis of collaborations between the 250 most political podcasters in the United States. My network analysis reveals that collaborations are much likelier between podcasters of similar ideological alignments, and these probabilities are the largest for left-wing podcasters. My research also shows that collaborations are highly unequal, adhering to power law distributions observed commonly across a wide range of social phenomena. My results advocate for a renewed focus on engagement between content creators on social media platforms as a potential driver of political polarization.

description: We discuss various types of exotic (non-standard) singularities in the Universe: a Big-Rip (BR or type I), a Sudden Future Singularity (SFS or type II), a Generalized Sudden Future Singularity, a Finite Scale Factor singularity (FSF or type III), a Big-Separation (BS or type IV) and a $w$-singularity. They are characterized by violation of all or some of the energy conditions which results in a blow-up of all or some of the physical quantities: the scale factor, the energy density, the pressure, and the barotropic index. We relate the emergence of these singularities with physical theories (superstring, brane, higher-order gravity, loop quantum cosmology). We show how the models involving exotic singularities may serve as dark energy by applying the observational data. In particular, we show that some of these exotic singularities (though being of a weak type according to relativistic definitions) may occur in the near future of the universe.

description: Applications of machine learning techniques in materials science are often based on two key ingredients, a set of empirical descriptors and a database of a particular material property of interest. The advent of graph neural networks, such as the Crystal Graph Convolutional Neural Network (CGCNN), demonstrates the possibility of directly mapping the relationship between material structures and properties without employing empirical descriptors. Another exciting recent advancement is in large language models such as OpenAI's GPT-4, which demonstrates competency at reading comprehension tasks and holds great promise for accelerating the acquisition of databases on material properties. Here, we utilize the combination of GPT-4 and CGCNN to develop rare-earth doped phosphors for solid-state lighting. GPT-4 is applied to data-mine chemical formulas and emission wavelengths of 264 Eu(II)-doped phosphors from 274 papers. A CGCNN model is trained on the acquired dataset, achieving a test $R^2$ of 0.77. The model is then used to screen over 40,000 inorganic materials to make predictions on the emission wavelengths. We also demonstrate the possibility of leveraging transfer learning to fine-tune a bandgap-predicting CGCNN model towards the prediction of phosphor emission wavelengths. The workflow requires minimal human supervision, little domain knowledge about phosphors, and is generalizable to other material properties.

Multivariate analyses of the macrozooplankton community and euphausiid larval ecology in the Prydz Bay region, Antarctica
Creators: name: Hosie, Graham William
Publisher: name: University Of Tasmania
Year: 2023

description: Macrozooplankton data from the Prydz Bay region, collected between 1981 and 1991, and representing the months of September to March, were analysed using duster analysis and non-metric multidimensional scaling to define the communities within the region, their distribution patterns, indicator species and species affinities. Four communities were identified. Three of these communities were dominated respectively by Euphausia crystallorophias (neritic), copepods-chaetognaths (main oceanic), and salpshyperiids-small euphausiids (northern oceanic community). The fourth community was characterized by the high abundance and dominance of the Antarctic krill, E. superba, and also by the paucity of zooplankton. This community was mainly located along the outer shelf edge, usually between the main oceanic and neritic communities. Chlorophyll a abundance and temperature explained much of the variation in community distribution patterns. The annual recession of ice, pack-ice cover, and salinity also explained some of the variation. Water circulation seemed to have only a clear effect on community distributions at the end of summer in March, when distributional patterns exhibited a distinct longitudinal zonation compared to the strong latitudinal pattern seen through most of the summer. In January 1984, 1985 and March 1987, net sampling surveys were carried out on the distribution and abundance of euphausiid larvae, primarily E. superba, in the Prydz Bay region. E. superba occurred in low abundance in January, probably due to sampling preceding the main spawning period, but occurred in very high abundance in the east of the region in March 1987. Thysanoessa macrura occurred throughout the study area in consistently high abundance. E. crystallorophias was marginally more abundant within its restricted range. Distinct north-south variations in larval age and developmental stages of T. macrura were observed indicating regional differences in spawning. Euphausia frigida was mainly confined to the upper 200 m of the Antarctic Circumpolar Current. E. superba larvae produced north of the shelf break, between 70 to 83¬¨‚àû E, moved north-east into the Antarctic Circumpolar Current. Larvae originating on the shelf moved rapidly west in the East Wind Drift. E. crystallorophias had the same westward dispersion, but some larvae appeared to return eastward via the Prydz Bay Gyre and remain in the region. However, the data indicate that most E. superba larvae, providing they survive injurious cold temperature and food deprivation, will leave the area, i.e. Prydz Bay krill may not be a self maintaining stock.

Cardiovascular response to beta-hydroxy thujaplicin and gamma-thujaplicin.
Creators: name: Moldowan, Mervin John
Publisher: name: University of British Columbia
Year: 2011

description: An Investigation was undertaken to determine the effects of beta-hydroxy thujaplicin and gamma-thujaplicin, used as the sodium salts, on blood pressure and heart rate in the rat. Attempts were made to discover the sites and modes of action of these two compounds. Gamma-thujaplicin 30mg/kg. produced either a vasopressor or a vasodepressor response in anesthetized rats. The pressor response was usually more pronounced, than the vasodepressor response. Tachycardia occurred with either blood pressure response. To determine whether the central nervous system was necessary for the vasopressor and tachycardiac response, pithed rats were used. In these preparations gamma-thujaplicin produced only a fall in blood pressure and a decrease in heart rate. The effect of adrenergic blocking drugs on the response to gamma-thujaplicin was investigated. In the anesthetized rat the vasopressor response was reduced significantly by both phenoxybenzamine and pronethalol; however, the heart rate was unaffected. In the pithed rat the vasodepressor response produced by gamma-thujaplicin was not affected by pronethalol; however, gamma-thujaplicin produced a significantly greater decrease in heart rate after treatment with pronethalol. To determine whether gamma-thujaplicin had adrenergic alpha-receptor or beta-receptor blocking properties its effect on blood pressure responses to noradrenaline and isoproterenol was investigated. Gamma-thujaplicin was found to reduce the vasopressor effect of intravenous noradrenaline 0.5ug/kg. but had no effect on the vasopressor response produced by isoproterenol 0.25ug/kg. The pressor response to intravenous physostigmine salicylate 40ug/kg. was unaffected by gamma-thujaplicin. The increase in heart rate and blood pressure produced by gamma-thujaplicin, with injections repeated every fifteen minutes, was greatly reduced after the second dose. It is concluded that in the anesthetized rats the vasopressor and tachycardiac response produced by gamma-thujaplicin were of central origin while the vasodepressor effect was a result of direct action on vascular smooth muscle. The vasopressor response could involve the stimulation, via sympathetic nerves, of alpha-adrenergic receptors of vascular smooth muscle. Gamma-thujaplicin can produce alpha-adrenergic receptor, blockade to exogenous noradrenaline, but not to endogenously released noradrenaline since the response to intravenous physostigmine was not affected by the tropolone. Beta-hydroxy thujaplicin 10mg/kg. caused a vasopressor response in all anesthetized and pithed rats tested. The vasopressor response was abolished by phenoxybenzamine in both anesthetized and pithed rats. Beta-hydroxy thujaplicin did not alter isoproterenol induced tachycardia or the vasopressor response produced by physostigmine salicylate. It is concluded that beta-hydroxy thujaplicin caused its vasopressor effect in rats by acting directly on the alpha-adrenergic receptors of vascular smooth muscle.

description: The dependence of fission barriers on the excitation energy of the compound nucleus impacts the survival probability of superheavy nuclei synthesized in heavy-ion fusion reactions. In this work, we investigate the isentropic fission barriers by means of the self-consistent nuclear density functional theory. The relationship between isothermal and isentropic descriptions is demonstrated. Calculations have been carried out for $^{264}$Fm, $^{272}$Ds, $^{278}$112, $^{292}$114, and $^{312}$124. For nuclei around $^{278}$112 produced in "cold fusion" reactions, we predict a more rapid decrease of fission barriers with excitation energy as compared to the nuclei around $^{292}$114 synthesized in "hot fusion" experiments. This is explained in terms of the difference between the ground-state and saddle-point temperatures. The effect of the particle gas is found to be negligible in the range of temperatures studied.

description: Change detection and irregular object extraction in 3D point clouds is a challenging task that is of high importance not only for autonomous navigation but also for updating existing digital twin models of various industrial environments. This article proposes an innovative approach for change detection in 3D point clouds using deep learned place recognition descriptors and irregular object extraction based on voxel-to-point comparison. The proposed method first aligns the bi-temporal point clouds using a map-merging algorithm in order to establish a common coordinate frame. Then, it utilizes deep learning techniques to extract robust and discriminative features from the 3D point cloud scans, which are used to detect changes between consecutive point cloud frames and therefore find the changed areas. Finally, the altered areas are sampled and compared between the two time instances to extract any obstructions that caused the area to change. The proposed method was successfully evaluated in real-world field experiments, where it was able to detect different types of changes in 3D point clouds, such as object or muck-pile addition and displacement, showcasing the effectiveness of the approach. The results of this study demonstrate important implications for various applications, including safety and security monitoring in construction sites, mapping and exploration and suggests potential future research directions in this field.

description: We present a theoretical study of a system consisting of a superconducting island and two quantum dots, a possible platform for building qubits and Cooper pair splitters, in the regime where each dot hosts a single electron and, hence, carries a magnetic moment. We focus on the case where the dots are coupled to overlapping superconductor states and we study whether the spins are ferromagnetically or antiferromagnetically aligned. We show that if the total number of particles is even, the spins align antiferromagnetically in the flatband limit, i.e., when the bandwidth of the superconductor is negligibly small, but ferromagnetically if the bandwidth is finite and above some value. If the total number of particles is odd, the alignment is ferromagnetic independently from the bandwidth. This implies that the results of the flatband limit are applicable only within restricted parameter regime for realistic superconducting qubit systems and that some care is required in applying simplified models to devices such as Cooper pair splitters.

description: We study the resummation of large logarithmic perturbative corrections to the partonic cross sections relevant for di-hadron production in hadronic collisions, H1 H2 -> h1 h2 X, at high invariant mass of the produced hadron pair. These corrections arise near the threshold for the partonic reaction and are associated with soft-gluon emission. We perform the resummation to next-to-leading logarithmic accuracy, and show how to incorporate consistently cuts in rapidity and transverse momentum of the observed particles. We present numerical results for fixed-target and ISR regimes and find enhancements over the next-to-leading order cross section, which significantly improve the agreement between theoretical predictions and data.

description: Several pulsar timing arrays including NANOGrav, EPTA, PPTA, and CPTA have recently reported the observation of a stochastic background of gravitational wave spectrum in the nano-Hz frequencies. An inflationary interpretation of this observation is challenging from various aspects. We report that such a signal can arise from the Chern-Simons coupling in axion inflation, where a pseudoscalar inflaton couples to a (massive) $U(1)$ gauge field, leading to efficient production of a transverse gauge mode. Such tachyonic particle production during inflation exponentially enhances the primordial perturbations and leads to a unique parity-violating gravitational wave spectrum, that remains flat near the CMB scales but becomes blue-tilted at smaller scales. We identify the parameter space consistent with various cosmological constraints and show that the resultant gravitational wave signals can provide extra contribution on top of the standard astrophysical contribution from inspiraling supermassive black hole binaries towards explaining the observed excess at NANOGrav. The parity-violating nature of the signal can be probed in future interferometers, distinguishing it from most other new physics signals attempting to explain the NANOGrav result.

description: Whenever two irreversible processes occur simultaneously, time-reversal symmetry of microscopic dynamics gives rise, on a macroscopic level, to Onsager's reciprocal relations, which impose constraints on the number of independent components of any transport coefficient tensor. Here, we show that in the antiferromagnetic YbMnBi$_2$, which displays a strong temperature-dependent anisotropy, the Onsager's reciprocal relations are strictly satisfied for anomalous electric ($σ^A_{ij}$) and anomalous thermoelectric ($α^A_{ij}$) conductivity tensors. In contradiction with what was recently reported by Pan $et~al.$ [Nat.Mater. 21, 203 (2022)], we find that $σ^A_{ij} (H)= σ^A_{ji} (-H)$, and $α^A_{ij} (H)= α^A_{ji} (-H)$. This equality holds in the whole temperature window irrespective of the relative weights of the intrinsic or extrinsic mechanisms. The $α^A_{ij}/σ^A_{ij}$ ratio is close to $k_B/e$ at room temperature, but peaks to an unprecedented magnitude of 2.9 $k_B/e$ at $\sim$ 150 K, which may involve nondegenerate carriers of small Fermi surface pockets.

We find that the single-photon with arbitrary wavevector can transport in a controllable way in this system. We also study how to realize controllable hopping interaction between two TLRs via a superconducting quantum interference device (SQUID). When the frequency of the SQUID is largely detuned from those of the two TLRs, the variables of the SQUID can be adiabatically eliminated and thus a controllable interaction between two TLRs can be obtained.

description: We analyze the isotropic component of turbulent flows spanning a broad range of Reynolds numbers. The aim is to identify scaling laws and their Reynolds number dependence in flows under different mechanical forcings. To this end, we applied an SO(3) decomposition to data stemming from direct numerical simulations with spatial resolutions ranging from 64^3 to 1024^3 grid points, and studied the scaling of high order moments of the velocity field. The study was carried out for two different flows obtained forcing the system with a Taylor-Green vortex or the Arn'old-Beltrami-Childress flow. Our results indicate that helicity has no significant impact on the scaling exponents. Intermittency effects increase with the Reynolds number in the range of parameters studied, and are larger than what can be expected from several models in the literature. Finally, we confirm previous results showing the use of the SO(3) decomposition improves the convergence of scaling exponents.

description: We studied the star cluster population properties in the nearby collisional ring galaxy NGC 922 using HST/WFPC2 photometry and population synthesis modeling. We found that 69% of the detected clusters are younger than 7 Myr, and that most of them are located in the ring or along the bar, consistent with the strong Halpha emission. The images also show a tidal plume pointing toward the companion. Its stellar age is consistent with pre-existing stars that were probably stripped off during the passage of the companion. We compared the star-forming complexes observed in NGC 922 with those of a distant ring galaxy from the GOODS field. It indicates very similar masses and sizes, suggesting similar origins. Finally, we found clusters that are excellent progenitor candidates for faint fuzzy clusters.

description: The aromatic bicomplex is an algebraic tool based on aromatic Butcher trees and used in particular for the explicit description of volume-preserving affine-equivariant numerical integrators. The present work defines new tools inspired from variational calculus such as the Lie derivative, different concepts of symmetries, and Noether's theory in the context of aromatic forests. The approach allows to draw a correspondence between aromatic volume-preserving methods and symmetries on the Euler-Lagrange complex, to write Noether's theorem in the aromatic context, and to describe the aromatic B-series of volume-preserving methods explicitly with the Lie derivative.

Labour force participation rates and poverty in Canadian metropolitan areas
Creators: name: Kunin, Roslyn
Publisher: name: University of British Columbia
Year: 2011

description: A theoretical model is developed explaining participation in the labour force in terms of the utility obtained from working, the likelihood of obtaining a job, and the costs associated with getting a job. Both discouraged and added worker behaviour are explained in terms of the model and the much greater likelihood of finding evidence of the former is noted. Regression analysis is then applied to 1961 census tract data for the major cities of Canada in order to discover the determinants of labour force participation rates and especially the influence of unemployment, on these rates. Separate regressions are run for high, middle, and low income tracts. Regressions are also separated by sex. For males, it is found that unemployment, wage levels, age, education, and marriage are important in determining participation rates. The influence of these variables differs significantly among the income groups. A strong discouraged worker effect is found. For women, similar results are found, but children, housing conditions, ethnic variables and the unemployment and earning rates of males also influence their labour force behaviour. Some slight evidence for added worker behaviour was found among the higher income groups. Similar regressions were then run using 1951 census data. Although there was evidence that the influence of some of the socio-demographic variables had changed over time, discouraged worker behaviour still predominated over added worker behaviour for all groups with the exception of higher income women. The results of this thesis were found to conform with the results obtained in earlier studies in the U.S. and Canada.
The lived experience of married women who place their husbands into a nursing home
Creators: name: Hills, T
Publisher: name: University Of Tasmania

description: The purpose of this study is to deepen understandings of the experience of married women who place their husbands into a nursing home. Interpretive research investigates our lived experience and addresses questions of being. A phenomenological study allows the particular and the unique meanings to be disclosed. Meaning and significance of placing one's husband into a nursing home remains hidden in much of the literature as a consequence of theoretical constructs entrenched within the positivist paradigm. The purpose of this study for nurses is found in bringing to the nursing discourse another perspective on this phenomenon. The insights gained from this study may radicalise thought and inform nursing practice. Conversation was chosen in anticipation of narrowing the gap between the researcher and the researched. These women's stories were descriptively written using their words. The philosophical thought of Heidegger helped guide the methodology and generate the understandings of the study. Through reflection on the conversations, understandings emerged. Three themes: connectedness; living out the tensions and re-discovery of self formed the thematic statement which describes the everyday experience of these three women. The lived experience of married women who place their husbands into a nursing home is expressed through a constant working towards maintaining a meaningful connection with their husband, whilst finding a new way of being as they live out the tensions associated with that placement.

description: We study low energy hadronic interaction models based on BESS observed cosmic ray proton and antiproton spectra at medium high altitude. Among the three popular low energy interaction models, we find that FLUKA reproduces results of BESS observations on secondary proton spectrum reasonably well over the whole observed energy range, the model UrQMD works well at relatively higher energies whereas spectrum obtained with GHEISHA differs significantly from the measured spectrum. Simulated antiproton spectrum with FLUKA, however, exhibits significant deviations from the BESS observation wheras UrQMD and GHEISHA reproduce the BESS observations within the experimental error.

description: The identification of an extrasolar planet as Earth-like will depend on the detection of atmospheric signatures or surface non-uniformities. In this paper we present spatially unresolved flux light curves of Earth for the purpose of studying a prototype extrasolar terrestrial planet. Our monitoring of the photometric variability of earthshine revealed changes of up to 23 % per hour in the brightness of Earth's scattered light at around 600 nm, due to the removal of specular reflection from the view of the Moon. This variability is accompanied by reddening of the spectrum, and results from a change in surface properties across the continental boundary between the Indian Ocean and Africa's east coast. Our results based on earthshine monitoring indicate that specular reflection should provide a useful tool in determining the presence of liquid water on extrasolar planets via photometric observations.

Optimal purification of a generic n-qudit state
Creators: name: Benenti, Giuliano

Subjects: subject: Quantum Physics (quant-ph)

description: We propose a quantum algorithm for the purification of a generic mixed state $ρ$ of a $n$-qudit system by using an ancillary $n$-qudit system. The algorithm is optimal in that (i) the number of ancillary qudits cannot be reduced, (ii) the number of parameters which determine the purification state $|Ψ>$ exactly equals the number of degrees of freedom of $ρ$, and (iii) $|Ψ>$ is easily determined from the density matrix $ρ$. Moreover, we introduce a quantum circuit in which the quantum gates are unitary transformations acting on a $2n$-qudit system. These transformations are determined by parameters that can be tuned to generate, once the ancillary qudits are disregarded, any given mixed $n$-qudit state.

description: We continue the study of a special entry in the AdS/CFT dictionary, namely a holographic formula relating the functional determinant of the scattering operator in an asymptotically locally anti-de Sitter (ALAdS) space to a relative functional determinant of the scalar Laplacian in the bulk. A heuristic derivation of the formula involves a one-loop quantum effect in the bulk and the corresponding sub-leading correction at large N on the boundary. We presently explore a higher-dimensional version of the spinning BTZ black hole obtained as a quotient of hyperbolic space by a discrete subgroup of isometries generated by a loxodromic (or hyperbolic) element consisting of dilation (temperature) and torsion angles (spinning). The bulk computation is done using heat-kernel techniques and fractional calculus. At the boundary, we get a recursive scheme that allows us to range from the non-spinning to the full-fledged spinning geometries. The determinants are compactly expressed in terms of an associated (Patterson-)Selberg zeta function and a connection to quasi-normal frequencies is discussed.

description: We report on the temperature dependence of microwave-induced resistance oscillations in high-mobility two-dimensional electron systems. We find that the oscillation amplitude decays exponentially with increasing temperature, as $\exp(-αT^2)$, where $α$ scales with the inverse magnetic field. This observation indicates that the temperature dependence originates primarily from the modification of the single particle lifetime, which we attribute to electron-electron interaction effects.

Ecology of bacteria from Antarctic hypersaline lakes
Creators: name: James, SJ
Publisher: name: University Of Tasmania
Year: 2023

description: There exists a unique and characteristic bacterial biota in Antarctic hypersaline lakes and 15 new bacterial species have been described from the lakes of the Vestfold Hills, Antarctica. In this study, antibodies were raised against the type strains of the four bacterial species which have been most consistently isolated from the oxylimnion of the hypersaline lakes of the Vestfold Hills. The abundance of these serogroups was measured throughout the austral spring and summer in four hypersaline lakes and a seawater site by indirect immunofluorescence microscopy. Maximum abundances of Halomonas serogroups (up to 40% of the total bacteria) and the Flavobacterium gondwanense serogroup (up tO 10% of the total bacteria) were observed at discrete depths within the water column in the two most hypersaline lakes at about midsummer, coincident with the time of maximum sunlight and the commencement of the summer thaw. Change in species abundance was not reflected in the total bacterial count, indicating compositional change of the total bacterial population. Concurrently, radioisotope incorporation methods were used to estimate heterotrophic bacterial productivity and metabolism. In the coastal marine site, incorporation rates were within the range previously reported for Antarctic ecosystems, ranging up to 2.1 pM thymidine h‚ÄövÖ¬™¬¨œÄ and 11.0 pM leucine h‚ÄövÖ¬™¬¨œÄ . Incorporation rates in the hypersaline lakes ranged up to 4.6 pM thymidine h‚ÄövÖ¬™¬¨œÄ and 94 pM leucine h‚ÄövÖ¬™¬¨œÄ . Generation times throughout all sample sites were fastest after the summer thaw at a depth of 2 m. Even at these peak times productivity in the hypersaline lakes was more than 100 times lower than average productivity in temperate aquatic environments. Optimum temperature for radioisotope incorporation was close to in-situ temperature in most cases, confirming the adaption of in-situ bacteria to the low water temperatures. Dissolved organic carbon (DOC) concentrations reflected the strong stratification and seasonal variation of other lake parameters. The ratio of [¬¨‚â•H]leucine incorporation to [¬¨‚â•H]thymidine incorporation (a measure of bacterial physiological state or species composition) correlated with DOC concentrations. DOC concentrations correlated well with total bacterial numbers but not with changes in species composition. In the meromictic hypersaline lakes, reduction of sulphur compounds is also an important means of energy generation. The Halomonas and Flavobacterium species isolated so far do not appear to be involved in sulphur cycling. However, a novel species of Brevibacterium, isolated and partly described in this study, reduces dimethylsulfoxide to dimethylsulphide and utilises methionine and cysteine as sole energy sources.
