description: In the current work we investigate the propagation of electromagnetic waves in the field of gravitational waves. Starting with simple case of an electromagnetic wave travelling in the field of a plane monochromatic gravitational wave we introduce the concept of surfing effect and analyze its physical consequences. We then generalize these results to an arbitrary gravitational wave field. We show that, due to the transverse nature of gravitational waves, the surfing effect leads to significant observable consequences only if the velocity of gravitational waves deviates from speed of light. This fact can help to place an upper limit on the deviation of gravitational wave velocity from speed of light. The micro-arcsecond resolution promised by the upcoming precision interferometry experiments allow to place stringent upper limits on $ε= (v_{gw}-c)/c$ as a function of the energy density parameter for gravitational waves $Ω_{gw}$. For $Ω_{gw} \approx 10^{-10}$ this limit amounts to $ε\lesssim 2\cdot 10^{-2}$.

description: Coronal mass ejections (CME) occur when long-lived magnetic flux ropes (MFR) anchored to the solar surface destabilize and erupt away from the Sun. This destabilization is often described in terms of an ideal magnetohydrodynamic (MHD) instability called the torus instability. It occurs when the external magnetic field decreases sufficiently fast such that its decay index, $n=-z\,\partial\,(\ln B)/\partial z$ is larger than a critical value, $n>n_{\rm cr}$, where $n_{\rm cr}=1.5$ for a full, large aspect ratio torus. However, when this is applied to solar MFRs, a range of conflicting values for $n_{\rm cr}$ is found in the literature. To investigate this discrepancy, we have conducted laboratory experiments on arched, line-tied flux ropes and have applied a theoretical model of the torus instability. Our model describes an MFR as a partial torus with footpoints anchored in a conducting surface and numerically calculates various magnetic forces on it. This calculation yields a better prediction of $n_{\rm cr}$ which takes into account the specific parameters of the MFR. We describe a systematic methodology to properly translate laboratory results to their solar counterparts, provided that the MFRs have sufficiently small edge safety factor, or equivalently, large enough twist. After this translation, our model predicts that $n_{\rm cr}$ in solar conditions often falls near $n_{\rm cr}^{\rm Sol}\sim0.9$ and within a larger range of $n_{\rm cr}^{\rm Sol}\sim(0.7,1.2)$ depending on the parameters. The methodology of translating laboratory MFRs to their solar counterparts enables quantitative investigations of the initiation of CMEs through laboratory experiments. These experiments allow for new physics insights that are required for better predictions of space weather events but are difficult to obtain otherwise.

description: Purpose: Prediction of developmental language disorder in children under 3 years of age is challenging. Among early risk factors, research has focused on having a positive familial history (FH+) for language or literacy problems and on late language emergence, that is, late-talker (LT) status. The interaction between these two risk factors and their cumulative effect is still debated. Here, we (a) investigate the effect of FH+ on 24-month language development, (b) test for cumulative effects of FH+ status and early language delay on 36-month language outcomes, and (c) disentangle the direct and indirect effects of familial history (FH) on the language outcome.Method: One hundred eighty-five Italian children were followed up longitudinally between 24 and 36 months of age (64 FH+ and 121 FH−) through parental questionnaires and direct child assessment.Results: At the age of 24 months, the FH+ group showed worse expressive vocabulary and higher prevalence of LT. At the age of 36 months, main effects of LT and FH were identified on lexical and phonological performances, respectively. Interestingly, significant interaction effects were identified on expressive vocabulary and phonological processing. Path analysis highlights that FH had a direct effect on later measures of phonology, whereas its effect on 36-month lexical abilities was indirect, via measures of expressive vocabulary at 24 months.Conclusions: The study suggests specific predictive roles of FH and LT status on language development. Interestingly, FH+ seems to represent an additive risk for LT children. The use of cumulative risk measures is confirmed as a powerful approach to identify those children with the highest probability of developing persistent language difficulties.Supplemental Material S1.

description: We have used the Hubble Space Telescope's Advanced Camera for Surveys (ACS) to detect and measure ~5300 stars in a single intracluster field in the Virgo Cluster. By performing F606W and F814W photometry on these stars, we have determined their metallicity distribution function, and constrained the types of stars present in this portion of Virgo's intracluster space. Based on the small number of stars detected brighter than the red giant branch (RGB) tip, we suggest that in this region, Virgo's intracluster stars are mostly old (>~10 Gyr). Through analysis of the RGB stars themselves, we determine that the population contains the full range of metallicities probed (-2.3-0.5. The spatial distribution of the most metal-poor stars in the field shows significantly more structure than that of the metal-rich stars, indicating that the intracluster population is not well-mixed. We discuss the implications these observations have for the production of intracluster stars and the dynamical evolution of the Virgo Cluster.

The evolution of the gas fraction of quiescent galaxies modeled as a consequence of their creation rate

description: We discuss the evolution of the interstellar medium of quiescent galaxies, currently emerging from recent analyses, with the help of a simple model based on well-established empirical relations such as the stellar mass functions and the main sequence of star formation. This model is meant to describe observed quantities without making specific assumptions on the nature of quenching processes, but relying on their observable consequences. We find that the high gas fractions seen or suggested at high redshift in quiescent galaxies, and their apparent mild evolution at early times, can be mostly attributed to a progenitor effect where recently quenched galaxies with ~10% gas fractions dominate the quiescent galaxy population until z~1. In the same context, the much lower gas and dust fractions measured in local early-type galaxies are interpreted as the product of the steady depletion of their interstellar medium on a ~2 Gyr timescale, coupled with a higher fraction of more gas-exhaustive events.

title: Optimising production of mannosylerythritol lipids by Pseudozyma graminicola through omic and molecular approaches
Creators: name: Solano Gonzalez, SC
Publisher: name: University of Liverpool Repository
Year: 2019

description: Mannosylerythritol lipids (MEL) are biosurfactants produced primarily by basidiomycete fungi. MELs have potential applications in a wide variety of fields, ranging from medicine to industrial emulsifiers, making them an important target for investigation. MEL production is species-specific, with different proportions of the four variants MEL A-D, being produced and secreted. Of the MEL producers characterised to date all have a five-gene biosynthetic MEL cluster, directly involved on the synthesis of the molecule. However, the mechanisms involved in the regulation of these genes remains unclear. The work described in this thesis contributes to the understanding of MEL production by Pseudozyma graminicola, which primarily produces MEL-C. First, we sequenced and annotated the P. graminicola genome, from which we identified the MEL cluster. Based on comparative genomic analysis, we report P. graminicola as a potential biotrophic plant pathogen. Then, we developed a 1HMR based semi-quantitative method to confirm and monitor MEL production. Alongside this we identified the optimal conditions for the production of MELs using two fermentation systems. Transcription of the MEL cluster genes was monitored during MEL producing and non-producing fermentation conditions using RNAseq and RT PCR. We developed a transformation protocol, which was applied to deletion of emt1 to validate the gene cluster function. We also used the same approach to investigate the roles of three transcription factors, areA, gti1 and pac2 with potential regulation roles in MEL production. Based on this analisis, deletion of gti1 and pac2 appear to result in reduced and enhanced MEL production, repectivly. Further detailed analysis of these mutant is now required to confirm and potentially exploit these findings. The developments described in this thesis contribute to better understanding the biology of P. graminicola associated to MEL production, providing the knowledge necessary for future development of high-yield strains.

urn:lsid:zoobank.org:act: D48D6295-ED03-4C79-81AE-6557CAFC07C8
Etymology. Gr. skolos, m., thorn, Gr. achlys, n, darkness, blackness or mist (after the ancient Greek goddess Achlys)
Definition. Thorectidae in which the irregular skeleton is composed of laminated fully cored primary fibres and secondary fibres that are also laminated, and often cored with detritus. It has partial or striated armour, anastomosing and fasciculating (bundles) of primary fibres, heavy collagen mesohyl, and a cavernous interior.
Diagnosis. Vase or saucer shaped sponges that have a black or dark brown exterior and yellow/green interior. The skeleton although cavernous is well supported by this yellowish dense collagenous matrix. The sponge has a very harsh and firm texture because of the massive fasciculating fibre bundles. It is the large cored laminated fibres that form massive fascicules that characterise this genus. It also has large laminated secondary fibres are often cored, which separates it from Hyrtios which always has heavy coring of the secondary fibres. The secondary fibres are almost as large as the primary fibres. The armour is partial, giving a striped or striated appearance due to the sand coring in the surface fibres.
Remarks. Skolosachlys gen. nov. differs is unique amongst the genera of Thorectinae by the partial striated armouring. It differs from other genera of Thorectinae that have partial armouring including Fascaplysinopsis and, Petrosaspongia by the coring of secondary fibres. The coring of secondary fibres also shows a marked difference from all other members of Thorectinae that have armouring i.e. Aplysinopsis, Thorecta and Thorectandra (Table 1). It is most easily separated however, either in the field or in the laboratory by simply cutting the sponge and observing the yellow collagenous interior contrasting with the darkbrown black harsh exterior. Skolosachlys gen. nov. can easily be distinguished in the field by the dark brown/black colour and the very harsh and firm texture of the sponge.
Type species: Skolosachlys enlutea sp. nov. here designated.

Shells in the Magellanic System

Year: 2006
Subjects: subject: Astrophysics (astro-ph)

description: The Magellanic System harbors >800 expanding shells of neutral hydrogen, providing a unique opportunity for statistical investigations. Most of these shells are surprisingly young, 2--10 Myr old, and correlate poorly with young stellar populations. I summarize what we have learned about shell properties and particularly focus on the puzzling correlation between the shell radius and expansion velocity. In the framework of the standard, adiabatic model for shell evolution this tight correlation suggests a coherent burst of star formation across the whole Magellanic System. However, more than one mechanism for shell formation may be taking place.

title: Race and Radicalisation: Examining Perceptions Of Counter-Radicalisation Policy Amongst Minority Groups in Liverpool 8 and 24.
Creators: name: Peatfield, EJ
Publisher: name: University of Liverpool Repository
Year: 2018

description: This thesis critically analyses the UK Government’s current counter-radicalisation policy, focusing in particular on groups presented as vulnerable or susceptible to the drivers of radicalisation outlined within the counter-radicalisation policy Prevent (2011). Although there have been a number of studies looking at the effect of counter-radicalisation policy on Muslim communities in Britain, this study is unique in its kind, as it examines the impact of counter-radicalisation policy on non Muslim minorities. This work draws attention to the linking of terrorism to socio economically marginalised groups and the concomitant gaze of surveillance or suspicion directed towards those considered risky. Based on the evidence gathered, it is argued that the negative framing of communities based on race and class has linked them to the risk of radicalisation through the construction of counterradicalisation drivers and vulnerabilities. To explore the intersectionality of race and class with assumptions embedded in counter-radicalisation policy, the research employed both quantitative and qualitative methodology to examinee minority communities in two areas of Liverpool. The research sought to gauge how much non-Muslim minorities knew about Prevent (2011) and the drivers identified in the document, alongside whether they believed they had been affected by counter-radicalisation/terrorism policy. The first phase was designed to position the research by considering the dynamics of identity construction. Phase two used semi-structured interviews to directly gauge the opinions of the groups highlighted for concern, in order to assess what they thought of as their own ‘vulnerabilities’, and the capacity of the ‘drivers of radicalisation’ identified in Prevent (2011) to influence behaviour and action. 3 | Page Race and Radicalisation E J Peatfield University of Liverpool The evidence presented in the thesis suggests that racialisation of Muslims and a re-classification of minority groups as Muslim have seen many non-Muslim minorities subject to the same security intrusions as many British Muslims, through an amalgamation of risk-based interventions and institutional discrimination. It is argued that the concepts of race and ethnicity can be fluid and linked with economic salience, which could act as a determinant for treatment and representation by the state. This research also suggests that class can intersect with race and ethnicity to create new targets for counter-radicalisation and counter-terrorism consideration. The negative framing of poor communities within policy can create a local resilience towards state intrusions, but also creates deep social divides.

description: Semiconducting Transition Metal Dichalcogenides (TMDs) have significant nonlinear optical effects. In this work we have used second-harmonic generation (SHG) and the four-wave mixing (FWM) spectroscopy in resonance with the excitons in MoS2, MoSe2, and WS2 monolayers to characterize the nonlinear optical properties of these materials. We show that trions and excitons are responsible for enhancing the nonlinear optical response, and determine the exciton and trion energies by comparing with the photoluminescence spectra. Moreover, we extract the second and third order optical sheet susceptibility near exciton energies and compare with values found in the literature. We also demonstrate the ability to generate different nonlinear effects in a wide spectral range in the visible region for monolayer MoS2, opening the possibility of using two-dimensional materials for nonlinear optoelectronic and photonic applications.

description: This short paper should serve as basis for further analysis of a previously found new symmetry of the solutions of the wave equation in the gravitational field of a Kerr black hole. Its main new result is the proof of essential self-adjointness of the spatial part of a reduced normalized wave operator of the Kerr metric in a weighted L^2-space. As a consequence, it leads to a purely operator theoretic proof of the well-posedness of the initial value problem of the reduced Klein-Gordon equation in that field in that L^2-space and in this way generalizes a corresponding result of Kay (1985) in the case of the Schwarzschild black hole. It is believed that the employed methods are applicable to other separable wave equations.

description: XL-Calibur is a hard X-ray (15-80 keV) polarimetry mission operating from a stabilised balloon-borne platform in the stratosphere. It builds on heritage from the X-Calibur mission, which observed the accreting neutron star GX 301-2 from Antarctica, between December 29th 2018 and January 1st 2019. The XL-Calibur design incorporates an X-ray mirror, which focusses X-rays onto a polarimeter comprising a beryllium rod surrounded by Cadmium Zinc Telluride (CZT) detectors. The polarimeter is housed in an anticoincidence shield to mitigate background from particles present in the stratosphere. The mirror and polarimeter-shield assembly are mounted at opposite ends of a 12 m long lightweight truss, which is pointed with arcsecond precision by WASP - the Wallops Arc Second Pointer. The XL-Calibur mission will achieve a substantially improved sensitivity over X-Calibur by using a larger effective area X-ray mirror, reducing background through thinner CZT detectors, and improved anticoincidence shielding. When observing a 1 Crab source for $t_{\rm day}$ days, the Minimum Detectable Polarisation (at 99% confidence level) is $\sim$2$\%\cdot t_{\rm day}^{-1/2}$. The energy resolution at 40 keV is $\sim$5.9 keV. The aim of this paper is to describe the design and performance of the XL-Calibur mission, as well as the foreseen science programme.

We show that the only non-trivial finite p-groups whose stable module categories have no non-trivial ghosts are the cyclic groups of order 2 and 3. We compare this to the situation in the derived category of a commutative ring. We also determine for which groups G the second power of the Jacobson radical of kG is stably isomorphic to a suspension of k.

description: The study's overarching objective was to identify the pitfalls and bottlenecks in ensuring environmental justice on an equal basis embedded in the existing legal, policy, and institutional framework. The environmental victims were examined, and the line experts' opinions were garnered. The study revealed that ordinary people could not seek justice to the court directly for environmental damage due to bubbles in the legal and policy framework. The courts suffer from various challenges like fuzziness in the jurisdiction, lack of legal advisor, and workloads. On the other hand, the court has no power to take cognizance of an offense independently. The wealthy and influential polluters are reluctant to respect the law due to insufficient punishment prescribed by the statutes. The victims are rarely compensated, and there are a few options to resolve the dispute in alternative ways. The provision of legal aid for the poor and disadvantaged people is not much helpful. The public departments are stuck with a lack of logistics and human resources. The jurisdictional overlapping, underlapping, and conflict of interest among the departments worsen monitoring, control, surveillance (MCS), and effective coordination. The regulatory framework does not welcome the community in decision making and natural resource management. Hence, the study recommends legal and institutional reform. Policy initiatives are warranted for effective environmental governance, green growth, campaign, and volunteerism.

A study of the Yiguan Dao (Unity Sect) and its development in Peninsular Malaysia
Creators: name: Soo, Khin Wah
Publisher: name: University of British Columbia
Year: 2009

description: This dissertation is a study of an important and widely adhered to sectarian religion in Peninsular Malaysia originating from Taiwan (and Hong Kong), namely the Unity Sect (Yiguan Dao). It is a lay voluntary religious organization of congregational character, with its own worship centres, organizational structure, rituals, and interpretation of both canonical and spirit-writing texts. The sect places much emphasis on the rehabilitation of morality in response to the degeneration of human behaviour; cultivation of morality constitutes one of the major remedies suggested by the sect. Nonetheless, it remains largely unknown to the general public and is faced with continuous verbal and written attacks, and was (and still is) accused by its opponents as a 'heretical' sect. Notwithstanding this, the sect has continued to progress with its proselytism at an even greater rate in the last two decades. To date, there is still no systematic study of the Yiguan Dao in Peninsular Malaysia, especially its recent development. It is the objective of this dissertation to provide a detailed description and analysis of the sect's organization, teachings, and rituals, to help the public understand better what the sect in actuality teaches, and how its rituals are conducted. Most importantly, based on first-hand research data, this study helps to draw the reader nearer to the real picture behind the success of the Unity Sect which is based on the strong religious convictions of its members. This study also discusses the ongoing institutionalization and intellectualization process of the sect in Taiwan and its implications for the sect's future development. In the concluding chapter, a further examination is carried out concerning the success of the sect's proselytism in the Peninsula from the perspectives of cultural and ethnic identities. The question of the Unity Sect's 'globalization' is also discussed in this chapter.

description: In this note we perform an analysis of the large set of microlensing events detected so far toward the Galactic center with the purpose of investigating whether some of the dark lenses are located in Galactic globular clusters. We find that in four cases some events might indeed be due to lenses located in the globular clusters themselves. We also give a rough estimate for the average lens mass of the subset of events being highly aligned with Galactic globular cluster centers and find that, under reasonable assumptions, the deflectors could most probably be either brown dwarfs, M-stars or stellar remnants.

description: Structural magnetic resonance imaging (MRI) has been widely utilized for analysis and diagnosis of brain diseases. Automatic segmentation of brain tumors is a challenging task for computer-aided diagnosis due to low-tissue contrast in the tumor subregions. To overcome this, we devise a novel pixel-wise segmentation framework through a convolutional 3D to 2D MR patch conversion model to predict class labels of the central pixel in the input sliding patches. Precisely, we first extract 3D patches from each modality to calibrate slices through the squeeze and excitation (SE) block. Then, the output of the SE block is fed directly into subsequent bottleneck layers to reduce the number of channels. Finally, the calibrated 2D slices are concatenated to obtain multimodal features through a 2D convolutional neural network (CNN) for prediction of the central pixel. In our architecture, both local inter-slice and global intra-slice features are jointly exploited to predict class label of the central voxel in a given patch through the 2D CNN classifier. We implicitly apply all modalities through trainable parameters to assign weights to the contributions of each sequence for segmentation. Experimental results on the segmentation of brain tumors in multimodal MRI scans (BraTS'19) demonstrate that our proposed method can efficiently segment the tumor regions.

Testing Lorentz and CPT Invariance with MINOS Near Detector Neutrinos

Year: 2008

description: We present an analysis designed to search for Lorentz and CPT violations as predicted by the SME framework using the charged current neutrino events in the MINOS near detector. In particular we develop methods to identify periodic variations in the normalized number of charged current neutrino events as a function of sidereal phase. To test these methods, we simulated a set of 1,000 experiments without Lorentz and CPT violation signals using the standard MINOS Monte Carlo. We performed an FFT on each of the simulated experiments to find the distribution of powers in the sidereal phase diagram without a signal. We then injected a signal of increasing strength into the sidereal neutrino oscillation probability until we found a 5$σ$ deviation from the mean in the FFT power spectrum. By this method, we can establish upper limits for the Lorentz and CPT violating terms in the SME.

Running of Running of the Spectral Index and WMAP Three-year data
Creators: name: Huang, Qing-Guo
Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Three-year data of WMAP implies not only a negative running of the spectral index with large absolute value, but also a large positive running of running of the spectral index with order of the magnitude $10^{-2}$. We calculate the running of running in usual inflation model and noncommutative inflation model. A large tensor-scalar ratio $r\geq 1.23$ is needed in order to fit the WMAP data in the noncommutative inflation model, which roughly saturates the observational upper bound on it.

description: We study the decoherence of two coupled spins that interact with a spin-bath environment. It is shown that the connectivity and the coupling strength between the spins in the environment are of crucial importance for the decoherence of the central system. For the anisotropic spin-bath, changing the connectivity or coupling strenghts changes the decoherence of the central system from Gaussian to exponential decay law. The initial state of the environment is shown to affect the decoherence process in a qualitatively significant manner.

Mass transfer to freely suspended particles at high Péclet number

description: In a theoretical analysis, we generalise well known asymptotic results to obtain expressions for the rate of transfer of material from the surface of an arbitrary, rigid particle suspended in an open pathline flow at large Péclet number, $\textrm{Pe}$. The flow may be steady or periodic in time. We apply this result to numerically evaluate expressions for the surface flux to a freely suspended, axisymmetric ellipsoid (spheroid) in Stokes flow driven by a steady linear shear. We complement these analytical predictions with numerical simulations conducted over a range of $\textrm{Pe} = 10^1 - 10^4$ and confirm good agreement at large Péclet number. Our results allow us to examine the influence of particle shape upon the surface flux for a broad class of flows. When the background flow is irrotational, the surface flux is steady and is prescribed by three parameters only: the Péclet number, the particle aspect ratio and the strain topology. We observe that slender prolate spheroids tend to experience a higher surface flux compared to oblate spheroids with equivalent surface area. For rotational flows, particles may begin to spin or tumble, which may suppress or augment the convective transfer due to a realignment of the particle with respect to the strain field.

description: Highest resolution laser spectroscopy has generally been limited to single trapped ion systems due to rapid decoherence which plagues neutral atom ensembles. Here, precision spectroscopy of ultracold neutral atoms confined in a trapping potential shows superior optical coherence without any deleterious effects from motional degrees of freedom, revealing optical resonance linewidths at the hertz level with an excellent signal to noise ratio. The resonance quality factor of 2.4 x 10^{14} is the highest ever recovered in any form of coherent spectroscopy. The spectral resolution permits direct observation of the breaking of nuclear spin degeneracy for the 1S0 and 3P0 optical clock states of 87Sr under a small magnetic bias field. This optical NMR-like approach allows an accurate measurement of the differential Lande g-factor between the two states. The optical atomic coherence demonstrated for collective excitation of a large number of atoms will have a strong impact on quantum measurement and precision frequency metrology.

Magnetic monopoles and center vortices as gauge-invariant topological defects simultaneously responsible for confinement

description: We give a gauge-invariant definition of the vortex surface in SU(N) Yang-Mills theory without using the gauge fixing procedure. In this construction, gauge-invariant magnetic monopoles with fractional magnetic charges emerge in the boundary of the non-oriented vortex surface such that the asymptotic string tension reproduces the correct $N$-ality dependence. We show that gauge-invariant magnetic monopoles and vortices are simultaneously responsible for quark confinement in four dimensional spacetime based on the Wilson criterion. These results are extracted from a non-Abelian Stokes theorem derived in the previous paper.

Runtime Safety Assurance Using Reinforcement Learning

description: The airworthiness and safety of a non-pedigreed autopilot must be verified, but the cost to formally do so can be prohibitive. We can bypass formal verification of non-pedigreed components by incorporating Runtime Safety Assurance (RTSA) as mechanism to ensure safety. RTSA consists of a meta-controller that observes the inputs and outputs of a non-pedigreed component and verifies formally specified behavior as the system operates. When the system is triggered, a verified recovery controller is deployed. Recovery controllers are designed to be safe but very likely disruptive to the operational objective of the system, and thus RTSA systems must balance safety and efficiency. The objective of this paper is to design a meta-controller capable of identifying unsafe situations with high accuracy. High dimensional and non-linear dynamics in which modern controllers are deployed along with the black-box nature of the nominal controllers make this a difficult problem. Current approaches rely heavily on domain expertise and human engineering. We frame the design of RTSA with the Markov decision process (MDP) framework and use reinforcement learning (RL) to solve it. Our learned meta-controller consistently exhibits superior performance in our experiments compared to our baseline, human engineered approach.
