 Nesothrips melinus Mound, 1974 a: 72. syn.n.
 This species was described from three females taken in southern New South Wales, and the synonym melinus from three males taken in Queensland. More recently the two sexes have been collected together from several sites in eastern New South Wales, the ACT, and southeastern Queensland. It is remarkably similar in general appearance to Nesothrips propinquus, but is readily distinguished by the different maxillary palps. The sexes differ significantly in colour. The females are brown to bicoloured, with the tube distinctively sharply pale yellow on the distal third (Fig. 22). In contrast, males are much paler, the body and tube with a brownish yellow gradient. Most specimens have been taken in leaf litter.
 Diagnosis. Apterous without ocelli, female brown or with head and thorax paler than dark abdomen, tube sharply pale yellow on distal third (Fig. 22); antennal segments I–II yellow, III–VI largely yellow with apices increasingly shaded brown, VII–VIII brown. Head slightly wider than long, not projecting in front of eyes; eyes with a cluster of about 3 ommatidia near ventral posterior margin but with only one ommatidium displaced to posterior (Fig.7); postocellar setae small and blunt, postocular setae longer and blunt; maxillary stylets one third of head width apart, retracted to eyes; maxillary palp segment I twice as long as wide, segment II longer than I with weak transverse lines; pronotal am small and acute; remaining 4 pairs blunt to weakly capitate; notopleural sutures complete; metanotum weakly sculptured; pelta wide, median lobe large, broadly connected to lateral areas, basal with continuos transverse sculpture (Fig. 43); tergites III–VI with transverse row of minute discal setae; tergite IX setae blunt and 0.6 as long as tube; tube shorter than head. Male smaller than female, mainly brownish yellow, tergite IX setae 0.8 as long as tube; fore tarsus with small sharp or stout tooth.

description: A guaranteed annual wage has been defined as "any plan in which an employer guarantees to all, or to a definite unit or group of his employees, a wage or employment for a specified period of time." However, the famous Latimer Report limits guaranteed wage plans to those which guarantee to employees work or wages for at least three months in a year. In the vast majority of guaranteed wage plans now in existence, employment is guaranteed for a specific number of weeks per year and hours per week, usually less than fifty-two weeks per year and forty hours per week.

description: Dwarf spheroidal galaxies that form in halo substructures provide stringent constraints on dark matter annihilation. Many ultrafaint dwarfs discovered with modern surveys contribute significantly to these constraints. At present, because of the lack of abundant stellar kinematic data for the ultrafaints, non-informative prior assumptions are usually made for the parameters of the density profiles. Based on semi-analytic models of dark matter subhalos and their connection to satellite galaxies, we present more informative and realistic satellite priors. We show that our satellite priors lead to constraints on the annihilation rate that are between a factor of 2 and a factor of 7 weaker than under non-informative priors. As a result, the thermal relic cross section can at best only be excluded (with 95% probability) for dark matter masses of $\lesssim 40$ GeV from dwarf spheroidal data, assuming annihilation into $b\bar{b}$.

description: Carientothrips mjobergi (Karny, 1920: 42)
(Figs 1, 33)
 Described from eastern Queensland, this species is widespread in dry sclerophyll Eucalyptus forest from Kangaroo Island in South Australia, and also Tasmania, northward throughout eastern Australia to Cairns in Queensland. A few specimens have also been seen from the southwest of Western Australia. This species was interpreted by Mound (1974 a) as having the eyes either prolonged or not prolonged ventrally, but this assumption is rejected here. The eyes of mjobergi are here considered to have a single ommatidium displaced to the posterior on the ventral surface. The body and legs are uniformly dark brown, with tarsi yellowish and fore tibiae lighter brown. In contrast, the tibiae of flavitibia and tasmanica are much paler. Females of mjobergi are usually macropterous, but in both sexes the fore wing length of flightless individuals is variable from micropterous to hemimicropterous. Similar variation in wing reduction is noted above in alienatus. The shape of the pelta varies, the median lobe being wider in major males, both micropterae and macropterae.
 Diagnosis. Body uniformly brown, tarsi and fore tibia brownish-yellow, antennal segment I–II brown, III–V yellow with gradually stronger shade of brown apices, VI brown but sometimes the short pedicel yellow, VII–VIII brown, tube dark brown with paler tip; wings slightly brownish. Head slightly longer than wide, slightly projecting in front of eyes (Fig. 1); eyes with one ommatidium displaced to posterior on ventral surface; postocellar setae small and acute, arising posterior to hind ocelli; postocular setae long and slightly blunt; maxillary stylets parallel about half of head width apart, retracted to postocular setae; maxillary palp segment I twice as long as wide, segment II slightly longer than I; pronotal am small slender and acute; aa, ml, epim, pa blunt to weakly capitate; notopleural sutures complete; pelta median lobe elongate, very narrowly connected to lateral wings (Fig. 33); tergite IX setae S1 blunt 0.8 as long as tube, S2 and S3 about as long as tube; tube shorter than head. Male smaller than female, particularly macropterous male; fore tarsus with stout tooth.

description: Recent observations [A.~Pustogow et al. Nature 574, 72 (2019)] of a drop of the $^{17}$O nuclear magnetic resonance (NMR) Knight shift in the superconducting state of Sr$_2$RuO$_4$ challenged the popular picture of a chiral odd-parity paired state in this compound. Here we use polarized neutron scattering to show that there is a $34 \pm 6$ % drop in the magnetic susceptibility at the ruthenium site below the superconducting transition temperature. Measurements are made at lower fields $H \sim \tfrac{1}{3} H_{c2}$ than a previous study allowing the suppression to be observed. Our results are consistent with the recent NMR observations and rule out the chiral odd-parity $\mathbf{d}=\hat{\mathbf{z}}(k_x\pm ik_y)$ state. The observed susceptibility is consistent with several recent proposals including even-parity $B_{1g}$ and odd-parity helical states.

description: Quantum phase estimation provides a path to quantum computation of solutions to Hermitian eigenvalue problems $Hv = λv$, such as those occurring in quantum chemistry. It is natural to ask whether the same technique can be applied to generalized eigenvalue problems $Av = λB v$, which arise in many areas of science and engineering. We answer this question affirmatively. A restricted class of generalized eigenvalue problems could be solved as efficiently as standard eigenvalue problems. A paradigmatic example is provided by Sturm--Liouville problems. Another example comes from linear ideal magnetohydrodynamics, where phase estimation could be used to determine the stability of magnetically confined plasmas in fusion reactors.

title: Assessment Of Bacterial Contamination Of Retrieved Musculoskeletal Allograft Tissue
Creators: name: Chowdhury, Nazim
Publisher: name: The Open University
Year: 2006

description: Tissues retrieved from cadavers are increasingly banked and used for transplantation but few bacteriological standards for the safety of the tissues have been established. This study sets out i) to investigate the sources of contamination of the cadaveric tissues, ii) to determine the optimal method for sampling of tissue for bacteria and iii) to assess the use of ethanol as a general purpose sterilant for contaminated tissues.

The sources of contamination were investigated by attempting to match the DNA fingerprints of bacteria recovered from tissue post retrieval with isolates recovered from donor’s skin, mortuary air and retrieval staff clothes. Isolates were identified to species level and DNA fingerprints were determined by random amplified polymorphic DNA (RAPD) profiling.

Contaminated tissues were found in 18 of 20 retrievals. Staphylococcal species, particularly coagulase negative species were among the most prevalent bacteria recovered from tissues. Staphylococcus epidermidis was present in 70% of the 20 retrievals, followed by Micrococcus spp. (50%), and S. capitis (45%). Other organisms were relatively uncommon, although Escherichia coli was recovered from 5 donors.

RAPD profiles showed that 16/35 (46%) of tissue and donor isolates of the same species from each retrieval were indistinguishable from each other and the corresponding rate of RAPD profiles of isolates from staff and tissue was 31%. There was no significant difference between the number of matches of isolates from donor and staff, and retrieved tissue isolates (P>0.05). Both staff and donor were the most common sources for contamination of cadaveric tissue during retrieval and to a lesser degree, the circulating air in mortuaries (20%).

Experiments showed that culturing of small aliquots of wash solutions was insensitive for the detection of bacteria. Culture of a filtered wash detected both high and low levels of contamination but was not reproducible. Swabbing of the tissue surface with a moist swab also gave variable results but did allow the growth of various bacteria following enrichment in liquid media.

Exposure to 70% ethanol for 60 min proved to be an effective sterilant of contaminated tendons, but it was necessary to remove as much muscle tissue as possible from the tissue before the treatment. Prewashing of tissue in a mild detergent improved the effectiveness of alcohol treatment.

description: Fisher's geometric model describes biological fitness landscapes by combining a linear map from the discrete space of genotypes to an $n$-dimensional Euclidean phenotype space with a nonlinear, single-peaked phenotype-fitness map. Genotypes are represented by binary sequences of length $L$, and the phenotypic effects of mutations at different sites are represented by $L$ random vectors drawn from an isotropic Gaussian distribution. Recent work has shown that the interplay between the genotypic and phenotypic levels gives rise to a range of different landscape topographies that can be characterised by the number of local fitness maxima. Extending our previous study of the mean number of local maxima, here we focus on the distribution of the number of maxima when the limit $L \to \infty$ is taken at finite $n$. We identify the typical scale of the number of maxima for general $n$, and determine the full scaled probability density and two point correlation function of maxima for the one-dimensional case. We also elaborate on the close relation of the model to the anti-ferromagnetic Hopfield model with $n$ random continuous pattern vectors, and show that many of our results carry over to this setting. More generally, we expect that our analysis can help to elucidate the fluctuation structure of metastable states in various spin glass problems.

description: A recent RIKEN experiment on the quenched $g_A$ in the superallowed Gamow-Telller transition from $^{100}$Sn indicates a role of scale anomaly encoded in the anomalous dimension $β^\prime$ of the gluonic stress tensor ${\rm Tr \ G}_{μν}^2$. This observation provides a support to the notion of hidden scale symmetry emerging by strong nuclear correlations with an IR fixed point realized -- in the chiral limit -- in the Nambu-Goldstone mode. We suggest there is an analogy in the way scale symmetry manifests in nuclear medium to the continuity from the unitarity limit at low density (in light nuclei) to the dilaton limit at high density (in compact stars). In between the limits, say, at normal nuclear matter density, the symmetry is not visible, hence hidden.

description: Both experiments and direct numerical simulations have been used to demonstrate that riblets can reduce turbulent drag by as much as $10\%$, but their systematic design remains an open challenge. In this paper, we develop a model-based framework to quantify the effect of streamwise-aligned spanwise-periodic riblets on kinetic energy and skin-friction drag in turbulent channel flow. We model the effect of riblets as a volume penalization in the Navier-Stokes equations and use the statistical response of the eddy-viscosity-enhanced linearized equations to quantify the effect of background turbulence on the mean velocity and skin-friction drag. For triangular riblets, our simulation-free approach reliably predicts drag-reducing trends as well as mechanisms that lead to performance deterioration for large riblets. We investigate the effect of height and spacing on drag reduction and demonstrate a correlation between energy suppression and drag-reduction for appropriately sized riblets. We also analyze the effect of riblets on drag reduction mechanisms and turbulent flow structures including very large scale motions. Our results demonstrate the utility of our approach in capturing the effect of riblets on turbulent flows using models that are tractable for analysis and optimization.

description: This paper develops an econometric price model with fundamental impacts for intraday electricity markets of 15-min contracts. A unique dataset of intradaily updated forecasts of renewable power generation is analysed. We use a threshold regression model to examine how 15-min intraday trading depends on the slope of the merit order curve. Our estimation results reveal strong evidence of mean reversion in the price formation mechanism of 15-min contracts. Additionally, prices of neighbouring contracts exhibit strong explanatory power and a positive impact on prices of a given contract. We observe an asymmetric effect of renewable forecast changes on intraday prices depending on the merit-order-curve slope. In general, renewable forecasts have a higher explanatory power at noon than in the morning and evening, but price information is the main driver of 15-min intraday trading.This article is part of the theme issue ‘The mathematics of energy systems’.

description: Observations of ultra-diffuse galaxies NGC 1052-DF2 and -DF4 show they may contain little dark matter, challenging our understanding of galaxy formation. Using controlled N-body simulations, we explore the possibility that their properties can be reproduced through tidal stripping from the elliptical galaxy NGC 1052, in both cold dark matter (CDM) and self-interacting dark matter (SIDM) scenarios. To explain the dark matter deficiency, we find that a CDM halo must have a very low concentration so that it can lose sufficient inner mass in the tidal field. In contrast, SIDM favors a higher and more reasonable concentration as core formation enhances tidal mass loss. Final stellar distributions in our SIDM benchmarks are more diffuse than the CDM one, and hence the former are in better agreement with the data. We further show that a cored CDM halo model modified by strong baryonic feedback is unlikely to reproduce the observations. Our results indicate that SIDM is more favorable for the formation of dark-matter-deficient galaxies.

description: The fundamental issue in the energetic performance of power plants, working both as traditional fuel engines and as combined cycle turbine (gas-steam), lies in quantifying the internal irreversibilities which are associated with the working substance operating in cycles. The purpose of several irreversible energy converter models is to find objective thermodynamic functions that determine operation modes for real thermal engines and at the same time study the trade off between energy losses per cycle and the useful energy. As those objective functions, we focus our attention on a generalization of the so-called ecological function in terms of an $ε$--parameter that depends on the particular heat transfer law used in the irreversible heat engine model. In this work, we mathematically describe the configuration space of an irreversible Curzon-Ahlborn type model. The above allows to determine the optimal relations between the model parameters so that a power plant operates in physically accessible regions, taking into account internal irreversibilities, introduced in two different ways (additively and multiplicatively). In addition, we establish the conditions that the $ε$--parameter must fulfill for the energy converter works in an optimal region between maximum power output and maximum efficiency points.

description: A supermassive black hole binary may form during galaxy mergering. we investigate the interaction of the supermassive binary black holes (SMBBHs) and an accretion disk and show that the detected X-shaped structure in some FRII radio galaxies may be due to the interaction-realignment of inclined binary and accretion disk occurred within the pc scale of the galaxy center. We compare in detail the model and observations and show that the configuration is consistent very well with the observations of X-shaped radio sources. X-shaped radio feature form only in FRII radio sources due to the strong interaction between the binary and a standard disk, while the absence of X-shaped FRI radio galaxies is due to that the interaction between the binary and the radiatively inefficient accretion flow in FRI radio sources is negligible. It is suggested that the binary would keep misaligned with the outer disk for most of the life time of FRII radio galaxies and the orientation of jet in most FRII radio galaxies distributes randomly, while the jets in most FRI radio galaxies is expected to be vertical to the accretion disk and thus the major axis of host galaxy. We discuss the relationship of X-shaped and double-double radio galaxies (DDRGs). The model is applied in paticular to two X-shaped radio sources 4C+01.30 and 3C293 and one DDRG source J0116-473 and show that the SMBBHs in the three objects have black hole mass ratios $q \sim 0.1 - 0.3$.

description: We propose accurate calculations of quasinormal modes of black holes in the Einstein-aether theory, which were previously considered in the literature, partially, with insufficient accuracy. We also show that the arbitrarily long-lived modes, quasiresonances, are allowed in the Einstein-aether theory as well and demonstrate that the asymptotic tails, unlike quasinormal frequencies, are indistinguishable from those in the Einstein theory.

description: For our research study, we wanted a better understanding of what factors influence students’ healthy beverage choices on UBC campus and how we can generate recommendations and ideas to making healthy beverages more accessible and available to the UBC students. We used students’ responses to a survey that measures which combination of factors of a beverage (organicity, locality, and caloric content) do they perceive as being healthy. Depending on each beverages quality, we also measured students’ willingness to pay for each condition. Our results showed that students are willing to pay the most for beverages which are organic, locally produced and have low caloric content. As for perceived healthiness, organicity and low caloric content of a drink are the most important qualities and is perceived as being the healthiest. Future suggestions to surrounding UBC with more stores that have organic, low caloric content and locally produced items so that students can make a better-informed healthier lifestyle choice.

 Diagnosis. Apterous or macropterous, body and legs brownish yellow with tube dark; head longer than wide, not projecting in front of eyes, vertex reticulate; eyes well developed dorsally but small ventrally with only 4–5 visible ommatidia; postocellar finely acute, postocular setae weakly capitate. Pronotal am setae short and acute, the other 4 pairs long and capitate, aa setae arising slightly mesad of anterior angle; notopleural sutures incomplete. Metanotum reticulate, with 4–6 minor setae anteromedially. Pelta broadly triangular with rounded margins (also macroptera); tergites III–VI with about 10 small discal setae in transverse row, wing-retaining setae minute in aptera, sigmoid in macroptera; tergite IX setae blunt and shorter than tube. Male with no fore tarsal tooth.

description: Distributed Denial of Service (DDoS) attacks are one of the most harmful threats in today's Internet, disrupting the availability of essential services. The challenge of DDoS detection is the combination of attack approaches coupled with the volume of live traffic to be analysed. In this paper, we present a practical, lightweight deep learning DDoS detection system called LUCID, which exploits the properties of Convolutional Neural Networks (CNNs) to classify traffic flows as either malicious or benign. We make four main contributions; (1) an innovative application of a CNN to detect DDoS traffic with low processing overhead, (2) a dataset-agnostic preprocessing mechanism to produce traffic observations for online attack detection, (3) an activation analysis to explain LUCID's DDoS classification, and (4) an empirical validation of the solution on a resource-constrained hardware platform. Using the latest datasets, LUCID matches existing state-of-the-art detection accuracy whilst presenting a 40x reduction in processing time, as compared to the state-of-the-art. With our evaluation results, we prove that the proposed approach is suitable for effective DDoS detection in resource-constrained operational environments.

description: We present a study of the dielectric function of metallic (III,Mn)V diluted magnetic semiconductors in the infrared regime. Our theoretical approach is based on the kinetic exchange model for carrier induced (III,Mn)V ferromagnetism. The dielectric function is calculated within the random phase approximation and, within this metallic regime, we treat disorder effects perturbatively and thermal effects within the mean field approximation. We also discuss the implications of this calculations on carrier concentration measurements from the optical f-sum rule and the analysis of plasmon-phonon coupled modes in Raman spectra.

description: The difficulty of deploying various deep learning (DL) models on diverse DL hardware has boosted the research and development of DL compilers in the community. Several DL compilers have been proposed from both industry and academia such as Tensorflow XLA and TVM. Similarly, the DL compilers take the DL models described in different DL frameworks as input, and then generate optimized codes for diverse DL hardware as output. However, none of the existing survey has analyzed the unique design architecture of the DL compilers comprehensively. In this paper, we perform a comprehensive survey of existing DL compilers by dissecting the commonly adopted design in details, with emphasis on the DL oriented multi-level IRs, and frontend/backend optimizations. Specifically, we provide a comprehensive comparison among existing DL compilers from various aspects. In addition, we present detailed analysis on the design of multi-level IRs and illustrate the commonly adopted optimization techniques. Finally, several insights are highlighted as the potential research directions of DL compiler. This is the first survey paper focusing on the design architecture of DL compilers, which we hope can pave the road for future research towards DL compiler.

description: Classical cash management models concern how an organisation should maintain their (liquid) cash balances in order to meet cash demands over time. In these models the balance can be increased or decreased to offset penalties for not being able to meet a cash demand or the opportunity cost of holding too much cash, respectively. The external source from which this money comes from or is sent to is not explicitly modelled but is assumed to be available at all times. In this thesis we contribute to the cash management problem by discussing three novel cash management models. To begin with, we include a second asset to the cash management model and assume the cash inflows are generated from this asset. We formulate this problem as a discrete Markov decision process (MDP) and solve it by the classic backward iteration method. We show that the optimal cash policy for this model possesses the two-threshold two-target form. Moreover we observe that the agent should take a ‘safer’ cash policy when the company has a balanced cash inflows and outflows. Then we introduce loan opportunities to the model. In this problem, we allow the agent taking loans from financial intermediates. We assume there is one type of unsecured loan with fixed interest rate and the manager can take this loan repeatedly once his previous debt is paid off. We also solve this model via the discrete MDP approach. Moreover we propose a heuristic for this problem based on the policy improvement which is shown to perform strongly in our experiments. At last, we consider an agent managing a cash account and a number of as- sets accounts. Hence both cash policies and asset allocation policies are studied simultaneously. Moreover we assume the agent wishes to pursuit the net profits while controlling the risk associated with his management strategies. We solve this model using a separable Piecewise linear approximate dynamic programming approach. We also provide a heuristic based on the myopic greedy algorithm and the discrete MDP approach as benchmarks. The numerical experiments show that the PWL ADP outperforms the heuristic in terms of objective values and takes significantly less solution time comparing with the discrete MDP.
