description: The rapid spread of the Coronavirus (COVID-19) confronts policy makers with the problem of measuring the effectiveness of containment strategies, balancing public health considerations with the economic costs of social distancing measures. We introduce a modified epidemic model that we name the controlled-SIR model, in which the disease reproduction rate evolves dynamically in response to political and societal reactions. An analytic solution is presented. The model reproduces official COVID-19 cases counts of a large number of regions and countries that surpassed the first peak of the outbreak. A single unbiased feedback parameter is extracted from field data and used to formulate an index that measures the efficiency of containment strategies (the CEI index). CEI values for a range of countries are given. For two variants of the controlled-SIR model, detailed estimates of the total medical and socio-economic costs are evaluated over the entire course of the epidemic. Costs comprise medical care cost, the economic cost of social distancing, as well as the economic value of lives saved. Under plausible parameters, strict measures fare better than a hands-off policy. Strategies based on current case numbers lead to substantially higher total costs than strategies based on the overall history of the epidemic.

The Austronesian migration hypothesis as seen from prehistoric settlements on the Karama River, Mamuju, West Sulawesi

description: My research in the Karama River sites was aimed at an assessment of its Neolithic sites in comparison with those in other regions of Island of Southeast Asia and the western Pacific. Close parallels in cultural assemblages between the Karama sites and contemporaries in Taiwan and the Philippines support the Out of Taiwan hypothesis, which corresponds most strongly with available linguistic and genetic evidence. Current evidence from the Karama Valley suggests a southward movement of Neolithic assemblages into the valley, from the north, at c. 3500 years ago. These assemblages included both the introduced domesticated pig (Sus scrofa) and domesticated rice (Oryza sativa japonica). However, the Neolithic material culture produced in the Karama Valley rapidly utilised local materials, and no definite imports have survived in the available assemblages. A sequence of settlement development can be suggested, especially based on the cultural assemblages from the sites of Kamassi, Minanga Sipakko and Bukit Pantaraan 1. The four main phases recognised commence with the initial establishment of Neolithic settlement, followed by the development and extension of settlement along the Karama River, then a period of decline and abandonment, and finally a re-use of some sites for burial. The pottery found in the earliest Neolithic sites, Kamassi and Minanga Sipakko, was predominantly red-slipped and otherwise undecorated. However, small amounts of circle stamped, punctate stamped and incised decoration were applied to the red-slipped pottery very early on, with more complex decoration developing during the middle phase of the Karama Neolithic. The increase in recorded sites during the middle phase perhaps denotes an increase in population by about 3000 BP. Wild game hunting, especially of the native Sus celebensis and Babyrousa sp., was also intensified at this time, along with a management of small numbers of domesticated Sus scrofa. About 2400 BP, the Karama sites underwent a significant reduction in numbers, and were apparently abandoned before the coming to the region of metal artefacts. Certain sites, such as Bukit Pantaraan 1 and probably Minanga Sipakko, were reused at this time for jar burial, which coincided. -- provided by Candidate.
Academic women in neoliberal times: Gender, time, space and emotion in the contemporary Australian university
Creators: name: Lipton, Briony
Publisher: name: The Australian National University
Year: 2019

description: The neoliberal transformation of higher education has a significant impact upon the careers of academic women. Despite women's inclusion across the organisational hierarchy, neoliberal new managerialism in Australian universities exacerbates gender inequity and inequitable practices in the way it redistributes power and reproduces and reinforces traditional gendered patterns of inequality. A focus on increased gender representation obscures the fact that women's participation continues to be measured and evaluated in relation to male norms of participation, and achievements and women remain largely invisible as academic leaders and respected knowledge producers. This thesis is a feminist examination of key discourses, which constitute academic performativity and identity in the contemporary Australian university. In particular, how the discourses of neoliberalism and feminism are entangled in the structures, systems, operations, and cultures of the university, and how they constitute academic identity and performance. Drawing on in-depth qualitative interviews with academic women in Australia and critical autoethnography, this thesis uses a mix of experimental methods to emphasise the performative and discursive decisions women make in regard to their academic careers. This thesis takes inspiration from Helene Cixous' (1987) ecriture feminine and Sara Ahmed's (2014) concept of 'willfulness' as a methodological approach that playfully displaces gender and sex in scholarly research and writing and allows for a re-imagining of the academic self.

description: Aims. Electrocardiography (ECG) has a high specificity but unfortunately low sensitivity to detect anatomic left ventricular hypertrophy (LVH). In this study, ECG amplitude and products were examined as continuous variables together with blood pressure (BP) and body mass index (BMI) to find out a simple method to predict echocardiographic (ECHO)-LVH. An age- and gender-stratified population-based sample of men (n = 121) and women (n = 135) aged 35–64 years enriched with newly diagnosed untreated hypertensive men (n = 138) and women (n = 97) in the Turku area in south-western Finland was studied. Major findings. Cornell voltage (or Cornell product), systolic BP (SBP) and BMI were all independent determinants of ECHO-LVH and left ventricular mass (LVM) indexed by height (LVMI). According to multivariate regression analyses with Cornell voltage (Cornell product), BMI and BP as explanatory variables, the three determinants explained 46–48% (47–49%) of the variation in LVMI among men and 50–54% (52–57%) among women. Score tables were constructed to estimate the probability of LVH. The estimated probability of ECHO-LVH increased in men gradually from 0% to 81% (79%) along with increased Cornell voltage (Cornell product) tertiles and in women respectively from 0% to 95% (97%). Conclusion. The sensitivity of ECG to detect ECHO-LVH can be markedly enhanced by using ECG amplitudes and products as continuous variables. The risk tables using Cornell voltages or products, BMI and SBP enable an easy and effective way to estimate the probability of ECHO-LVH.
Exploring laser-driven neutron sources for neutron capture cascades and the production of neutron-rich isotopes

description: The production of neutron-rich isotopes and the occurrence of neutron capture cascades via laser-driven (pulsed) neutron sources are investigated theoretically. The considered scenario involves the interaction of a laser-driven neutron beam with a target made of a single type of seed nuclide. We present a comprehensive study over $95$ seed nuclides in the range $3\le Z \le 100$ from $^7_3$Li to $^{255}_{100}$Fm. For each element, the heaviest sufficiently-long-lived (half life $> 1$ h) isotope whose data is available in the recent ENDF-B-VIII.0 neutron sublibrary is considered. We identify interesting seed nuclides with good performance in the production of neutron-rich isotopes where neutron capture cascades may occur. The effects of the neutron number per pulse, the neutron-target interaction size and the number of neutron pulses are also analyzed. Our results show the possibility of observing up to $4$ successive neutron capture events leading to neutron-rich isotopes with $4$ more neutrons than the original seed nuclide. This hints at new experimental possibilities to produce neutron-rich isotopes and simulate neutron capture nucleosynthesis in the laboratory. With several selected interesting seed nuclides in the region of the branching point of the $s$-process ($^{126}_{51}$Sb, $^{176}_{71}$Lu and $^{187}_{75}$Re) or the waiting point of the $r$-process (Lu, Re, Os, Tm, Ir and Au), we expect that laser-driven experiments can shed light on our understanding of nucleosynthesis.

description: Based on the two-step protocol [Phys. Rev. A68(03)042317], we propose a $(n,n)$-threshold multiparty quantum secret sharing protocol of secure direct communication. In our protocol only all the sharers collaborate can the sender's secure direct communication message be extracted. We show a variant version of this protocol based on the variant two-step protocol. This variant version can considerably reduce the realization difficulty in experiment. In contrast to the use of multi-particle GHZ states in the case that the sharer number is larger than 3, the use and identification of Bell states are enough in our two protocols disregarding completely the sharer number, hence, our protocols are more feasible in technique.

description: We present a new stellar population synthesis model, which predicts SEDs for single-age single-metallicity stellar populations, SSPs, at resolution 1.5A (FWHM) in the spectral region of the near-IR CaII triplet feature. The main ingredient of the model is a new extensive empirical stellar spectral library presented in Cenarro et al., which is composed of more than 600 stars. Two main products of interest for stellar population analysis are presented. The first is a library of SEDs for SSPs covering a large range of ages, metallicities and different IMF types. They are well suited to model galaxy data, since the SSP spectra, with flux-calibrated response curves, can be smoothed to match the resolution of galaxy data, taking into account the internal velocity dispersion of the galaxy, allowing the user to analyze the observed spectrum in its own system. We also produce integrated absorption line indices for the same SSPs in the form of equivalent widths. We find the following behaviour for the CaII feature in old-aged SSPs: i) the CaII triplet feature does not change much with time for all metallicities for ages larger than ~3 Gyr, ii) this index shows a strong dependence with metallicity for values below [M/H] ~-0.5 and iii) for larger metallicities this feature does not show a significant dependence either on age or on the metallicity, being more sensitive to changes in the slope of power-like IMF shapes. The SSP spectra have been calibrated with measurements for globular clusters. Fitting the models to two early-type galaxies of different luminosities, we find that the CaII measurements cannot be fitted unless a very dwarf-dominated IMF is imposed, or if the Ca abundance is even lower than the Fe abundance.

description: In the perpetual struggle between high-speed predators and their prey, individuals need to react in the blink of an eye to avoid capture. Alarm calls that warn of danger therefore need to do so sufficiently rapidly that listeners can escape in time. Paradoxically, many species produce more elements in their alarm calls when signalling about more immediate danger, thereby increasing the reliability of transmission of critical information but taking longer to convey the urgent message. We found that New Holland honeyeaters, Phylidonyris novaehollandiae, incorporated more elements in alarm calls given to more dangerous predators, but video analysis revealed that listeners responded in 100 ms, after only the first element. Consistent with this rapid response, the acoustic structure of the first element varied according to the danger, and playbacks confirmed that birds need only hear the first element to assess risk. However, birds hid for longer and were more likely to flee, after calls with more elements. The dual mechanisms of varying both element structure and number may provide a widespread solution to signalling rapidly and reliably about immediate danger.

description: We use a cluster algorithm to study the critical behavior of strongly coupled lattice QCD in the chiral limit. We show that the finite temperature chiral phase transition belongs to the O(2) universality class as expected. When we compute the finite size effects of the chiral susceptibility in the low temperature phase close to the transition, we find clear evidence for chiral singularities predicted by chiral perturbation theory (ChPT). On the other hand it is difficult to reconcile the quark mass dependence of various quantities near the chiral limit with ChPT.

 Remarks. There is some uncertainty as to the identity of this species, originally described from a single female from Taiwan. We take the identity of the species from Okada (1977) as first reviser, who examined the female type and figured a male specimen from Japan. Specimens from the Ryukyus Islands (near Taiwan) figured here, also match this identity. The species was also treated by Kitbamroong & Freytag (1978) who also examined and figured the female type. However, the male specimen they figured from Thailand could represent a different species as, although the figures lack detail, the aedeagus looks different to that figured here. They also recorded the species from Vietnam and the Philippines. Our specimen from Vietnam is a new species described below.

We derive a corresponding Markovian Master Equation under usual assumption of weak coupling using the projection operator techniques, in two opposite regimes of very small and very large modulation frequency. Special attention is granted to the case of uniformly (globally) modulated interaction, where some general results concerning the Floquet normal form of a solution and its asymptotic stability are also addressed.

description: This thesis develops models and methods to investigate leisure, technology and growth. Models in chapters two, three and four study the macroeconomic impacts of technology on the consumer side. The models allow for consumer habit formation for a technology good purchased for leisure. However, for the consumption good, habits are irrelevant. A method is introduced to determine the steady state of the technology good sector and consumption good sector in- dependently. These chapters show that the models can contribute to the theoretical and empirical understanding of changes in consumption growth, interest rates, labour income share and wages. Models are constructed in chapters five and six to analyse technology on the production side in the form of job replacement by robots. Chapter five shows that the impact on welfare is ambiguous because leisure in the utility function can mitigate against wage decreases. In chapter six, policy to mitigate job losses from technology/robots is discussed.
Modelling the distributions of white dwarf atmospheric pollution: a low Mg abundance for accreted planetesimals?

description: The accretion of planetesimals onto white dwarf atmospheres allows determination of the composition of this polluting material. This composition is usually inferred from observed pollution levels by assuming it originated from a single body. This paper instead uses a stochastic model wherein polluting planetesimals are chosen randomly from a mass distribution, finding that the single body assumption is invalid in >20% of cases. Planetesimal compositions are modelled assuming parent bodies that differentiated into core, mantle and crust components. Atmospheric levels of Ca, Mg and Fe in the model are compared to a sample of 230 DZ white dwarfs for which such pollution is measured. A good fit is obtained when each planetesimal has its core, mantle and crust fractions chosen independently from logit-normal distributions which lead to average mass fractions of $f_\text{Cru}=0.15$, $f_\text{Man}=0.49$ and $f_\text{Cor}=0.36$. However, achieving this fit requires a factor 4 depletion of Mg relative to stellar material. This depletion is unlikely to originate in planetesimal formation processes, but might occur from heating while the star is on the giant branch. Alternatively the accreted material has stellar abundance, and either the inferred low Mg abundance was caused by an incorrect assumption that Mg sinks slower than Ca and Fe, or there are unmodelled biases in the observed sample. Finally, the model makes predictions for the timescale on which the observed pollutant composition varies, which should be the longer of the sinking and disc timescales, implying variability on decadal timescales for DA white dwarfs.

description: Understanding the fluid-structure interaction is crucial for an optimal design and manufacturing of soft mesoscale materials. Multi-core emulsions are a class of soft fluids assembled from cluster configurations of deformable oil-water double droplets (cores), often employed as building-blocks for the realisation of devices of interest in bio-technology, such as drug-delivery, tissue engineering and regenerative medicine. Here, we study the physics of multi-core emulsions flowing in microfluidic channels and report numerical evidence of a surprisingly rich variety of driven non-equilibrium states (NES), whose formation is caused by a dipolar fluid vortex triggered by the sheared structure of the flow carrier within the microchannel. The observed dynamic regimes range from long-lived NES at low core-area fraction, characterised by a planetary-like motion of the internal drops, to short-lived ones at high core-area fraction, in which a pre-chaotic motion results from multi-body collisions of inner drops, as combined with self-consistent hydrodynamic interactions. The onset of pre-chaotic behavior is marked by transitions of the cores from one vortex to another, a process that we interpret as manifestations of the system to maximize its entropy by filling voids, as they arise dynamically within the capsule.

description: Stroke leads to reduced cardiorespiratory fitness (CRf) and increased risk of future cardiovascular events. Cardiac rehabilitation (CR), has been shown to reduce the risk of future cardiovascular events in cardiac patients. The use of CR for the stroke population has only been explored in one study in England. This study provided CR for stroke patients for 30 weeks and focussed on people with very mild severity stroke.The overall aim of this thesis was to establish the feasibility of conducting a definitive study investigating the effect of six weeks of adapted CR on CRf, blood pressure, heart rate, activity levels, quality of life, fatigue, tone, falls, body mass index, anxiety and depression for people with mild to moderate stroke in the sub-acute stage of recovery. Feasibility was determined by: acceptability, ability to recruit, adherence to the programme, identifying outcome measures and adverse events. This mixed-methods thesis reports firstly on the attitudes and knowledge of healthy lifestyles in people post stroke and their thoughts on attending CR. Secondly, it identifies the attitudes of stroke and CR teams towards people with stroke attending CR and the adaptations that would be needed. These two phases informed the design of the final cohort study by identifying the CR adaptations needed and the recruitment strategies to be used.The third phase of this thesis reports on the results of a validity and reliability study which aimed to identify the most valid and reliable clinical test of CRf in people with mild-to-moderate severity stroke. The Incremental Shuttle walk test (ISWT) was shown to have modest validity (r=0.58, 95% confidence intervals (CI) 0.34-0.75, p=0.001) and strong reliability (ICC of 0.99, 95% CI 0.96-0.99) for measuring CRf in people post-stroke and this measure was used in the final phase of the thesis. Finally, this thesis reports on the results of a mixed-methods cohort study that integrated people with stroke into CR programmes in the sub-acute phase of recovery.It was found that adapted CR: was acceptable to people with NIHSS <3, the stroke and cardiac teams if suitable support and training provided, and the cardiac patients; had acceptable recruitment; had high adherence and only one adverse event; and identified outcome measures that could measure change. It concludes that a definitive study to explore CR for a very mild stroke population (NIHSS <3) is feasible with appropriate adaptations and support.

description: A living cell's interior is one of the most complex and intrinsically dynamic systems, providing an elaborate interplay between cytosolic crowding and ATP-driven motion, which controls cellular functionality. Here, we investigated two distinct fundamental features of the merely passive, not-bio-motor shuttled material transport within the cytoplasm of Dictyostelium discoideum cells: the anomalous non-linear scaling of the mean-squared displacement of a 150nm-diameter particle and non-Gaussian distribution of increments. Relying on single-particle tracking data of 320,000 data points, we performed a systematic analysis of four possible origins for non-Gaussian transport: (1) sample-based variability, (2) rare occurring strong motion events, (3) ergodicity breaking/ageing, and (4) spatio-temporal heterogeneities of the intracellular medium. After excluding the first three reasons, we investigated the remaining hypothesis of a heterogeneous cytoplasm as cause for non-Gaussian transport. A novel fit model with randomly distributed diffusivities implementing medium heterogeneities suits the experimental data. Strikingly, the non-Gaussian feature is independent of the cytoskeleton condition and lag time. This reveals that efficiency and consistency of passive intracellular transport and the related anomalous scaling of the mean-squared displacement are regulated by cytoskeleton components, while cytoplasmic heterogeneities are responsible for the generic, non-Gaussian distribution of increments.

description: We use recent results from the Wilkinson Microwave Anisotropy Probe (WMAP) for the locations of peaks and troughs of the Cosmic Microwave Background (CMB) power spectrum, together with constraints from large-scale structure, to study a quintessence model in which the pure exponential potential is modified by a polynomial factor. We find that the model is compatible with all the recent data for a wide range of cosmological and potential parameters. Moreover, quintessence is favoured compared to $Λ$CDM for $n_s\approx 1$ and relatively high values of the average fraction of dark energy before last scattering (``early quintessence''); for $n_s<1$, quintessence and $Λ$CDM give similar results, except for high values of early quintessence, in which case $Λ$CDM is favoured.

CIZ1 as a therapeutic target for glioblastoma
Creators: name: Paxton, Matheson
Publisher: name: Lancaster University
Year: 2024

description: Glioblastoma is a devastating disease with a median survival of 12 – 15
 months. It is the most common brain tumour in adults and current standard
 treatments remain poor. Surgery and radiotherapy only improve patient
 prognosis short term and the only available chemotherapy (TMZ) is
 ineffective in half of the patients that receive it as their tumours
 develop a resistant phenotype. CIZ1 is a nuclear protein with DNA
 replication, epigenetic maintenance, and genome stability functions. CIZ1
 is overexpressed in many cancers, including glioblastoma, and is evidenced
 to drive tumourigenesis. CDK inhibition therapy has showed recent promise
 in the treatment of cancer and some FDA approved CDK4/6 inhibitors are now
 used in routine breast cancer treatment. CDK inhibitors have been trialled
 in glioblastoma patients, showing some efficacy, however it is
 hypothesised that CDK inhibition may reduce CIZ1 levels to reduce
 glioblastoma growth. Here, we assess the effect of a panel of six CDK
 inhibitors on glioblastoma (U-87 MG and BTNW914) and normal glia (SVG p12)
 cell lines. CDK inhibition causes reduced glioblastoma cell proliferation,
 cell cycle arrest and cell death in 2D and 3D culture, as well as a high
 selectivity over normal glia. The effect on CIZ1 levels has proved
 inconclusive and requires further investigation. Overall, these data
 identify that CDK inhibitors have promising efficacy in reducing
 proliferation and reducing cell death in glioblastoma models in vitro, and
 should be further investigated in pre-clinical models.

Yellow marked with orange on vertex and disc of pronotum and scutellum; a narrow brown band on face below ocelli and three laterally on pronotum. Forewing with a small brown spot in third apical cell.
 External features as in S. dellagiustinai (Figs 1–3). Head relatively narrow in dorsal view with vertex slightly longer than basal width; fore margin of the head truncate in lateral view; clypeus narrow dorsally and antennae situated relatively high on face. Forewing with two recurved costal veins from outer subapical cell.
 Male genitalia with pygofer, subgenital plate and connective as in S. dellagiustinai (Figs 5, 8–9): pygofer without processes, broadly rounded apically in lateral view with a group of very long setae apically and a few shorter setae subapically. Subgenital plate distinctly shorter than pygofer, broad basally with distal two thirds very narrow in ventral view; a uniseriate row of macrosetae subbasally and a few short fine setae distally. Connective with a pair of slender paraphyses, each paraphysis tapering distally. Style as in S. dellagiustinai (Fig. 4) but apical process more elongate. Aedeagus disassociated from connective; shaft elongate, slightly longer than basal apodeme, with a pair of short apical processes and a dorsal serrated flange basally on each side, gonopore apical on posterior surface; basal apodeme compressed anteroposteriorly, produced into a lobe on each side at midlength (Figs 15, 16).

description: The performance of the ATLAS muon trigger system is evaluated with proton-proton ($pp$) and heavy-ion (HI) collision data collected in Run 2 during 2015-2018 at the Large Hadron Collider. It is primarily evaluated using events containing a pair of muons from the decay of $Z$ bosons to cover the intermediate momentum range between 25 GeV and 100 GeV. Overall, the efficiency of the single-muon triggers is about 68 % in the barrel region and 85% in the endcap region. The $p_{\text{T}}$ range for efficiency determination is extended by using muons from decays of $J/ψ$ mesons, $W$ bosons, and top quarks. The performance in HI collision data is measured and shows good agreement with the results obtained in $pp$ collisions. The muon trigger shows uniform and stable performance in good agreement with the prediction of a detailed simulation. Dedicated multi-muon triggers with kinematic selections provide the backbone to beauty, quarkonia, and low-mass physics studies. The design, evolution and performance of these triggers are discussed in detail.

description: We describe a method to map the standing-wave pattern inside a Fabry-Perot optical cavity with sub-wavelength resolution by perturbing it with a commercially available scanning near-field optical microscope (SNOM) tip. The method is applied to a fiber Fabry-Perot microcavity. We demonstrate its use to determine the relative position of the antinodes at two different wavelengths. In addition, we use the SNOM tip as a point-like source allowing precise positioning of a microscope objective with respect to the cavity mode.

 Remarks. The unique type of S. baeticus (BMNH) remains of uncertain identity as its abdomen is missing, the abdomen was originally stated as being “mutilated”. It differs from other similar species in having the transverse band on the vertex dark brown rather than orange, the dark brown transverse bands on the face coalescing to form an irregular triangular-shaped spot, the area below each antenna dark brown and the pronotum without orange markings.

Root, Bulb, and Acorn : Sowing seeds of care, connection, and community
Creators: name: Adebar, Tess
Publisher: name: The University of British Columbia

description: Quercus garryana, or Garry oak, is western Canada’s only native oak tree. It grows within a complex web of associated ecosystems, including the Garry oak meadow. The ecological legacy of thousands of years of Indigenous landscape management, less than 5% of Garry oak ecosystems are still standing. However, due to climate change, their suitable range is forecasted to increase. While many Pacific Northwest tree species are expected to struggle under shifting heat and drought regimes, Garry oak is well-adapted to flourish. Root, Bulb, and Acorn aims to increase the diversity and resilience of Vancouver’s urban forest by creating plots of Garry oak meadows within three parks in Vancouver: Tatlow Park, Oak Meadows Park, and Queen Elizabeth Park. The acts of planting, tending and maintaining these plots will foster the well-being of the meadows, as well as a renewed appreciation for Garry oak. Performing small-scale interventions with largescale impacts, this project aims to plant seeds of care, connection, and community to grow alongside the ecology of this unique and vital ecosystem.
Chiral symmetry restoration in QC_2D from effective model using the functional renormalization group

description: The order of the chiral phase transition in two-color and two-flavor QC$_2$D is investigated using the functional renormalization group (FRG) technique in an effective model setting. We calculate the $β$ function of all couplings in the dimensionally reduced Ginzburg-Landau free energy functional with Pauli-Gürsey SU(4) symmetry. We compare results of the perturbative $ε$ expansion approach with those obtained via the FRG, evaluated directly in $d=3$ dimensions. The perturbative results suggest that the fixed-point structure is more intricate than that of three-color QCD, a conclusion further supported by the FRG analysis. Both methods display an infrared stable $O(6)$ fixed point at infinite axial anomaly; however, the FRG approach also reveals the existence of $U_A(1)$ anomaly-free fixed points, which can become infrared stable if the anomaly in the underlying theory vanishes at the critical temperature. These findings imply that the phase transition can be of second order, consistent with earlier findings for three colors.

Conductance oscillations in strongly correlated fractional quantum Hall line junctions

description: We present a detailed theory of transport through line junctions formed by counterpropagating single-branch fractional-quantum-Hall edge channels having different filling factors. Intriguing transport properties are exhibited when strong Coulomb interactions between electrons from the two edges are present. Such strongly correlated line junctions can be classified according to the value of an effective line-junction filling factor n that is the inverse of an even integer. Interactions turn out to affect transport most importantly for n=1/2 and n=1/4. A particularly interesting case is n=1/4 corresponding to, e.g., a junction of edge channels having filling factor 1 and 1/5, respectively. We predict its differential tunneling conductance to oscillate as a function of voltage. This behavior directly reflects the existence of novel Majorana-fermion quasiparticle excitations in this type of line junction. Experimental accessibility of such systems in current cleaved-edge overgrown samples enables direct testing of our theoretical predictions.

 Material examined. INDIA: Syntype ♀ (Platyretus albosignatus Distant), Darjeeling (BMNH).
 Remarks. This species looks similar externally to the figures of Scaphoideus varius Vilbaste (1968) from Russia, given by Lee (1979), of which the line drawing habitus figure was originally produced in the description of S. hongdoensis Kwon & Lee from Korea. Presumably therefore, the un-stated synonymy of S. varius and S. hongdoensis in Lee (1979) dates from that publication. Both sets of male genitalia figures are the same. Strangely, none of the references in Kwon & Lee’s 1978 paper (including Vilbaste’s) appear in the text of their paper, suggesting perhaps that the paper was extracted from a larger work.

description: Accurate prediction of mercury content emitted from fossil fueled power stations is of utmost important for environmental pollution assessment and hazard mitigation. In this paper, mercury content in the output gas of power stations boilers was predicted using adaptive neuro fuzzy inference system method integrated with particle swarm optimization. The input parameters of the model include coal characteristics and the operational parameters of the boilers. The dataset has been collected from a number of power plants and employed to educate and examine the proposed model. To evaluate the performance of the proposed ANFIS PSO model the statistical meter of MARE was implemented. Furthermore, relative errors between acquired data and predicted values presented, which confirm the accuracy of the model to deal nonlinearity and representing the dependency of flue gas mercury content into the specifications of coal and the boiler type.

Dynamical instability criterion for circular (vorton) string loops

description: Dynamic perturbation equations are derived for a generic stationary state of an elastic string model -- of the kind appropriate for representing a superconducting cosmic string -- in a flat background. In the case of a circular equilibrium (i.e. vorton) state of a closed string loop it is shown that the fundamental axisymmetric ($n=0$) and lowest order ($n=1$) nonaxisymmetric perturbation modes can never be unstable. However, stability for modes of higher order ($n\geq 2$) is found to be non-trivially dependent on the values of the characteristic propagation velocity, $c$ say, of longitudinal perturbations and of the corresponding extrinsic perturbation velocity, $v$ say. For each mode number the criterion for instability is the existence of nonreal roots for a certain cubic eigenvalue equation for the corresponding mode frequency. A very simple sufficient but not necessary condition for reality of the roots and therefore absence of instability is that the characteristic velocity ratio, $c/v$ be greater than or equal to unity. Closer examination of the low velocity (experimentally accessible) nonrelativistic regime shows that in that limit the criterion for instability is just that the dimensionless characteristic ratio $c/v$ be less than a critical value $χ_c$ whose numerical value is approximately $1\over 2$. In the relativistic regime that is relevant to superconducting cosmic strings the situation is rather delicate, calling for more detailed investigation that is postponed for future work.
