title: Developing the role of PCR for detection and characterisation of helicobacters in human infection
Creators: name: Chisholm, Stephanie Angela
Publisher: name: The Open University
Year: 2004

description: This study aimed to explore and develop the role of PCR in the investigation of human Helicobacter infections. Overall performance of PCR assays (both conventional and real-time) was influenced by certain key factors, notably specimen transport conditions, DNA extraction methods, primers, and inherent target sequence variation. PCR-based detection and characterisation of non-viable H. pylori in gastric biopsies demonstrated the benefit of this approach as an alternative to culture, while the design and application of the first PCR test to detect both H. pylori and 'H. heilmannii'-like organisms (HHLOs) showed a higher rate of HHLO infection (2.3 %) than had been reported previously. The potential of PCR for further strain characterisation was demonstrated by determining clarithromycin susceptibility direct from gastric biopsy by a real-time PCR (LightCycler) assay for mutation detection. Development of an analogous test for metronidazole appears less feasible, as examination of a unique strain set suggested that, contrary to earlier reports, genetic mutations in rdxA and frxA may not be the principal resistance mechanism. Additionally, development of a novel multiplex PCR assay to determine vacA genotypes direct from gastric biopsies provided a useful tool to facilitate surveillance and confirmed that the s 1ml genotype is a common feature of peptic ulcer disease-associated isolates. Application of three novel LightCycler PCR assays to detect cagA tyrosine phosphorylation motifs (TPMs) demonstrated that TPM A was common in South East England. No significant associations were observed between disease status and cagA TPM. Extension of the PCR-based approach for non-invasive detection of H. pylori from stool specimens showed that it was less sensitive and less specific than stool antigen testing. Nevertheless, development of real-time nested PCRs that performed identically to conventional assays demonstrated the potential for next-day diagnosis from stools and offered the possibility of future screening of larger populations. Application of PCR to investigate extra-gastric chronic inflammatory conditions provided the first evidence of H. pylori DNA in the human bladder, although its significance as a causal factor in human disease remains unclear. The study provides new evidence to support wider use of conventional and real-time PCR-based assays as powerful tools for future investigation of gastric and extra-gastric Helicobacter infections.

description: Following the recent success of deep neural networks (DNN) on video computer vision tasks, performing DNN inferences on videos that originate from mobile devices has gained practical significance. As such, previous approaches developed methods to offload DNN inference computations for images to cloud servers to manage the resource constraints of mobile devices. However, when it comes to video data, communicating information of every frame consumes excessive network bandwidth and renders the entire system susceptible to adverse network conditions such as congestion. Thus, in this work, we seek to exploit the temporal coherence between nearby frames of a video stream to mitigate network pressure. That is, we propose ShadowTutor, a distributed video DNN inference framework that reduces the number of network transmissions through intermittent knowledge distillation to a student model. Moreover, we update only a subset of the student's parameters, which we call partial distillation, to reduce the data size of each network transmission. Specifically, the server runs a large and general teacher model, and the mobile device only runs an extremely small but specialized student model. On sparsely selected key frames, the server partially trains the student model by targeting the teacher's response and sends the updated part to the mobile device. We investigate the effectiveness of ShadowTutor with HD video semantic segmentation. Evaluations show that network data transfer is reduced by 95% on average. Moreover, the throughput of the system is improved by over three times and shows robustness to changes in network bandwidth.

description: The spin photocurrents, direct currents induced by light, hold great promise for introducing new elements to spintronics. However, a general theory for spin photocurrents in real materials which is applicable to systems with spin-orbit coupling or noncollinear magnetism is absent. Here, we develop such a general theory of second-order spin photocurrents. We find that the secondorder spin photocurrents can be classified into Drude, Berry curvature dipole, shift, injection, and rectification currents, which have different physical origins and symmetry properties. Surprisingly, our theory predicts a direct pure spin rectification current in an insulator induced by photons with energies lower than the material band gap. This phenomenon is absent in the case of the charge photocurrent. We find that the pure spin current of BiTeI induced by subgap light is large enough to be observable in experiments. Moreover, the subgap pure spin photocurrent is highly tunable with the polarization of light and the flowing direction of the spin photocurrent. This study lays the groundwork for the study of nonlinear spin photocurrents in real materials and provides a route to engineer light-controlled spin currents.

description: The distribution of electrons and of electrical at the free surface if strange quark matter are determined within the framework of the MIT bag model. It is shown that, with the allowance for the betta-decay of quarks near the surface due to the outward escape of electrons, the electric charge density of quarks at the surface increases by a factor of 17-25, the thickness of the transitional layer decreases from 230 Fm to 15 Fm, and the field strength increases by a factor of 1.7. The difference between the chemical potentials of electrons at the surface and deep layers decreases from 7 MeV to 0.8 MeV, which increases the limiting possible density of ordinary matter above a strange quark star.

description: Economic activity at both the micro and macro levels assumes constant comparison of the results of activities and costs associated with it, determining the most effective option for action. Objective assessment of the enterprise activity, involving the calculation and analysis of indicators of efficiency takes priority. The paper deals with assessment of the economic efficiency of operating activities of agricultural enterprises on the basis of an improved approach. The analysis of efficiency of operating activities is based on the example of the data of a particular agricultural enterprise from the country with a transition economy. Analysis of the efficiency of the operating activities of enterprise on the basis of calculating of profitability of sold agricultural products and return of sales are conducted; the necessity of calculation of these indicators based on operating profit is underlined. To obtain more complete information on the state of the enterprise’s efficiency, it is proposed to determine the overall indicator of profitability of operating activities. The mechanism of distribution of total revenues and costs by kinds of production is considered. It is proposed to classify the concept of «operational activities» into operational production and operational non-production activities.

description: Repeated computations on the same molecular system, but with different geometries, are often performed in quantum chemistry, for instance, in ab-initio molecular dynamics simulations or geometry optimizations. While many efficient strategies exist to provide a good guess for the self-consistent field procedure, which is usually the main computational task to be performed, little is known on how to efficiently exploit in this direction the abundance of information generated during the many computations. In this article, we present a strategy to provide an accurate initial guess for the density matrix, expanded in a set of localized basis functions, within the self-consistent field iterations for parametrized Hartree-Fock problems where the nuclear coordinates are changed along a few user-specified collective variables, such as the molecule's normal modes. Our approach is based on an offline-stage where the Hartree-Fock eigenvalue problem is solved for some particular parameter values and an online-stage where the initial guess is computed very efficiently for any new parameter value.The method allows non-linear approximations of density matrices, which belong to a non-linear manifold that is isomorphic to the Grassmann manifold.The so-called Grassmann exponential and logarithm map the manifold onto the tangent space and thus provides the correct geometrical setting accounting for the manifold structure when working with subspaces rather than functions itself.Numerical tests on different amino acids show promising initial results.

description: Stellar ejecta gradually enrich the gas out of which subsequent stars form, making the least chemically enriched stellar systems direct fossils of structures formed in the early universe. Although a few hundred stars with metal content below one thousandth of the solar iron content are known in the Galaxy, none of them inhabit globular clusters, some of the oldest known stellar structures. These show metal content of at least ~0.2 percent of the solar metallicity ([Fe/H] > -2.7). This metallicity floor appears universal and it has been proposed that proto-galaxies that merge into the galaxies we observe today were simply not massive enough to form clusters that survived to the present day. Here, we report the discovery of a stellar stream, C-19, whose metallicity is less than 0.05 per cent the solar metallicity ([Fe/H]=-3.38 +/- 0.06 (stat.) +/- 0.20 (syst.)). The low metallicity dispersion and the chemical abundances of the C-19 stars show that this stream is the tidal remnant of the most metal-poor globular cluster ever discovered, and significantly below the purported metallicity floor: clusters with significantly lower metallicities than observed today existed in the past and contributed their stars to the Milky Way halo.

description: An \hi survey of 10 dE/dS0 galaxies in the nearby Sculptor and Centaurus A groups was made using the Australia Telescope Compact Array (ATCA). The observed galaxies have accurate distances derived by Jerjen et al (1998; 2000b) using the surface brightness fluctuation technique. Their absolute magnitudes are in the range $-9.5 > M_B > -15.3$. Only two of the ten galaxies were detected at our detection limit ($\sim 1.0 \times 10^6$ \msol for the Centaurus group and $\sim 5.3 \times 10^5$ \msol for the Sculptor group), the two dS0 galaxies ESO384-016 in the Centaurus A Group and NGC 59 in the Sculptor Group, with \hi masses of $6.0 \pm 0.5 \times 10^6$ \msol and $1.4 \pm 0.1 \times 10^7$ \msol respectively. Those two detections were confirmed using the Green Bank Telescope. These small \hi reservoirs could fuel future generations of low level star formation and could explain the bluer colors seen at the center of the detected galaxies. Similarly to what is seen with the Virgo dEs, the two objects with \hi appear to be on the outskirt of the groups.

description: C-V2X (Cellular Vehicle-to-Everything) is the important enabling technology for autonomous driving and intelligent transportation systems. It evolves from LTE (Long Term Evolution)-V2X to NR (New Radio)-V2X, which will coexist and be complementary with each other to provide low latency, high reliability, and high throughput communications for various C-V2X applications. In this article, a vision of C-V2X is presented. The requirements of the basic road safety and advanced applications, the architecture, the key technologies, and the standards of C-V2X are introduced, highlighting the technical evolution path from LTE-V2X to NR-V2X. Especially, based on the continual and active promotion of C-V2X research, field testing and development in China, the related works and progresses are also presented. Lastly, the trends of C-V2X applications with technical challenges are envisioned.
title: Abnormalities of HLA and β₂microglobulin expression on tumour cells
Creators: name: Bicknell, David Charles
Publisher: name: The Open University
Year: 2003

description: This thesis describes the genetic events that can lead to the loss of expression of HLA class 1 on tumour cells. Earlier studies, in colorectal cancer, have shown both complete loss of surface HLA A, B & C expression and loss of single allele products using antibodies recognizing either monomorphic or polymorphic HLA determinants. Data presented demonstrates that complete loss of HLA class 1 expression correlates with mutations in β2 microglobulin. In a study of 52 colorectal cell lines, 8 showed mutations in β2 microglobulin leading to loss or reduced HLA expression. In fresh colorectal tumours 9/147 had mutations in β2 microglobulin, occurring at single or di-nucleotide repeat sequences. From these tumours 71 were analyzed for microsatellite instability, associated with the loss of DNA mismatch repair, and 7 (10%) found to be unstable. β2 microglobulin mutations were identified in 5 of these tumors. Therefore, mutations in β2 microglobulin occur more frequently in mismatch repair defective tumours than in colorectal tumours in general (p<0.01). The colorectal cell line HCA-7 lacks expression of HLA-A*0101 based on studies with the polymorphic antibody 142.2, but the normal B cell line (EVA-1224) from the same patient expresses A*0101. This thesis shows that the A*0101 gene, in HCA-7, contains an insertion of a cytidine in a cytidine repeat sequence in exon 4. This mutated A*0101 gene has the similar sequence to that of a rare A*0104'null' allele reported to lack A*0104 expression. In a model system a β2 microglobulin-HLA-A*0201 construct was transfected, using an ecdysone inducible expression system, into CHO cells and expression shown to be under the control of the inducer, Ponasterone A. Functional studies demonstrated the construct to be capable of presenting the flu virus peptide GILGFVFTL to a clone of human A*0201 restricted cytotoxic T cells and for the T cells to efficiently lyse the CHO cells.

description: We present the results of a series of XMM-Newton EPIC and OM observations of Her X-1, spread over a wide range of the 35 day precession period. We confirm that the spin modulation of the neutron star is weak or absent in the low state - in marked contrast to the main or short-on states. During the states of higher intensity, we observe a substructure in the broad soft X-ray modulation below ~1keV, revealing the presence of separate peaks which reflect the structure seen at higher energies. The strong fluorescence emission line at ~6.4keV is detected in all observations (apart from one taken in the middle of eclipse), with higher line energy, width and normalisation during the main-on state. In addition, we report the detection of a second line near 7keV in 10 of the 15 observations taken during the low-intensity states of the system. This feature is rather weak and not significantly detected during the main-on state, when the strong continuum emission dominates the X-ray spectrum. Spin resolved spectroscopy just after the rise to the main-on state shows that the variation of the Fe Kalpha line at 6.4 keV is correlated with the soft X-ray emission. This confirms our past finding based on the XMM-Newton observations made further into the main-on state, and indicates the common origin for the thermal component and the Fe Kalpha line detected at these phases. We also find that the normalisation of the 6.4keV line during the low state is correlated with the binary orbital phase, having a broad maximum centered near phi_(orbit) ~ 0.5. We discuss these observations in the context of previous observations, investigate the origin of the soft and hard X-rays and consider the emission site of the 6.4keV and 7keV emission lines.

We prove one of the probabilistic identities, relating a random vector of last passage percolation times to its dual, using the duality between the Robinson-Schensted-Knuth and Burge correspondences. A second probabilistic identity, relating those two vectors to a vector of "last swap times" in the oriented swap process, is conjectural. We give a computer-assisted proof of this identity for $n\le 6$ after first reformulating it as a purely combinatorial identity, and discuss its relation to the Edelman-Greene correspondence.

description: Heavy metal contamination is becoming an increasing environmental problem worldwide. Heavy metals (HM) retard plant growth, yield and affect the secondary metabolism which results in fluctuations in plant metabolites, such as the alkaloids. The aim of the study was to investigate the influence of HM on the growth of in vitro cultivated plants of Chelidonium majus and their alkaloid content. The plants were cultivated on a medium B5 with double the amount of macrosalts, 0.5 g/l activated charcoal and supplemented with different concentrations of HM – Cd2+ (0.5; 1 mg/l); Pb2+ (100; 250 mg/l); Zn2+ (100; 250 mg/l). Plants were obtained in vitro from seeds or were propagated through adventitious shooting (AS). The raw alkaloid mixtures (RAM) were obtained by usual chemical procedure.
 Plants cultivated at the lower concentration of Cd2+ formed roots and developed normally with a gradual reduction in their growth and rooting as the concentration of the supplemented HM increased. There were not any differences in the development of the plants cultivated on Cd2+ according to their type of origin. Epinasty and browning of the leaves were observed among the plants cultivated on the medium supplemented with Pb2+. These side effects got worse as the concentration of the HM increased, and were also accompanied by a strong reduction in the rooting. The plants which were obtained from seeds developed normally and did not show any of the signs of the ones which were propagated through AS. None of the plants cultivated on a medium supplemented with Zn2+ survived, regardless of their origin and HM concentration. A phytochemical study showed that the plants cultivated at the highest concentrations of Cd2+  and Pb2+  and also obtained through AS had the highest RAM. However, the plants cultivated at the same concentrations but obtained from seeds had lower RAM similar to that of the plants cultivated at lower concentrations of HM and propagated through AS.
 In conclusion, Ch. majus was able to cope with the influence of Cd2+  and Pb2+  in the culture medium, but not with that of Zn2+. Quantity of RAM was influenced by the HM concentration and the origin of the plants.

description: The rare radiative $B$-meson decay $B^-\toγ\ell^-\barν$ and the radiative Higgs-boson decay $h\toγγ$ mediated by light-quark loops both receive large logarithmic corrections in QCD, which can be resummed using factorization theorems derived in soft-collinear effective theory. In these factorization theorems the same radiative jet function appears, which is a central object in the study of factorization beyond the leading order in scale ratios. We calculate this function at two-loop order both in momentum space and in a dual space, where its renormalization-group evolution takes on a simpler form. We also derive the two-loop anomalous dimension of the jet function and present the exact solution to its evolution equation at two-loop order. Another important outcome of our analysis is the explicit form of the two-loop anomalous dimension of the $B$-meson light-cone distribution amplitude in momentum space.

description: The preparation of mesoscopic states of the radiation and matter fields through atom-field interactions has been achieved in recent years and employed for a range of striking applications in quantum optics. Here we present a technique for the preparation and control of a cavity mode which, besides interacting with a two-level atom, is simultaneously submitted to linear and parametric amplification processes. The role of the amplification-controlling fields in the achievement of real mesoscopic states, is to produce highly-squeezed field states and, consequently, to increase both: i) the distance in phase space between the components of the prepared superpositions and ii) the mean photon number of such superpositions. When submitting the squeezed superposition states to the action of similarly squeezed reservoirs, we demonstrate that under specific conditions the decoherence time of the states becomes independent of both the distance in phase space between their components and their mean photon number. An explanation is presented to support this remarkable result, together with a discussion on the experimental implementation of our proposal. We also show how to produce number states with fidelities higher than those derived as circular states.

This paper proposes a protocol and a platform based on Blockchain Technology that enables the transparent processing of personal data throughout its lifecycle from capture, lineage to redaction. The solution intends to help service multiple stakeholders from individual end-users to Data Controllers and Privacy Officers. It intends to offer a holistic and unambiguous view of how and when the data points are captured, accessed, and processed. The framework also envisages how different access control policies might be created and enforced through a public blockchain including real time alerts for privacy data breach.

description: A new type of noised induced phase transitions is proposed. It occurs in noisy systems with dynamical traps. Dynamical traps are regions in the phase space where the regular forces are depressed substantially. By way of an example, a simple oscillatory system {x,v} with additive white noise is considered and its dynamics is analyzed numerically. The dynamical trap region is assumed to be located near the x-axis where the velocity v of the system becomes sufficiently low. The meaning of this assumption is discussed. The observed phase transition is caused by the asymmetry in the residence time distribution in the vicinity of zero value velocity. This asymmetry is due to a cooperative effect of the random Langevin force in the trap region and the regular force not changing the direction of action when crossing the trap region.

description: Thought experiments involving gases and pistons, such as Maxwell's demon and Gibbs' mixing, are central to our understanding of thermodynamics. Here we present a quantum thermodynamic thought experiment in which the energy transfer from two photonic gases to a piston membrane grows quadratically with the number of photons for indistinguishable gases, while linearly for distinguishable gases. This signature of Bosonic bunching may be observed in optomechanical experiments, highlighting the potential of these systems for the realisation of thermodynamic thought experiments in the quantum realm.

description: In a recent paper dealing with maximum likelihood detection of gravitational wave chirps from coalescing binaries with unknown parameters we introduced an accurate representation of the no-signal cumulative distribution of the supremum of the whole correlator bank. This result can be used to derive a refined estimate of the number of templates yielding the best tradeoff between detector's performance (in terms of lost signals among those potentially detectable) and computational burden.

description: We study the simplest $SO(2)$ gauged $O(5)$ Skyrme models in $4+1$ (flat) dimensions. In the gauge decoupled limit, the model supports topologically stable solitons (Skyrmions) and after gauging, the static energy of the solutions is bounded from below by a "baryon number". The studied model features both Maxwell and Maxwell--Chern-Simons dynamics. The considered configurations are subject to bi-azimuthal symmetry in the ${\mathbb R}^4$ subspace resulting in a two dimensional subsystem, as well as subject to an enhanced symmetry relating the two planes in the ${\mathbb R}^4$ subspace, which results in a one dimensional subsystem. Numerical solutions are constructed in both cases. In the purely magnetic case, fully bi-azimuthal solutions were given, while electrically charged and spinning solutions were constructed only in the radial (enhanced symmetric) case, both in the presence of a Chern-Simons term, and in its absence. We find that, in contrast with the analogous models in $2+1$ dimensions, the presence of the Chern-Simons term in the model under study here results only in quantitative effects.

description: The University of British Columbia Food Systems is an ongoing project aimed at targeting various components of the UBC food system and providing recommendations for improvements in their sustainability. Our task was to conduct a triple bottom line assessment of product group that is purchased by the Alma Mater Society Food and Beverage Department and University of British Columbia Food Services. After communication with representatives of these organizations we decided to conduct our triple bottom line assessment of the primary sugar products used. We conducted extensive research through communication, both in person and through e-mail, with further representatives of our stakeholders, conducted online research of journal articles and various other literature sources, and investigated pricings by direct phone contact to applicable companies. We focused our research on the analysis of the sustainability from an ecologic, social, and economic lens, in order to satisfy the ‘triple bottom line’. Our ecologic analysis determined that organic sugarcane (Saccharum spp.) production was preferable; our social analysis determined that conventional sugarcane production is fraught with negative social impacts that can be avoided by purchasing sugar beet (Beta vulgaris) sugar or fair trade cane sugar; our economic analysis found that organic fair trade sugar incurs a significant cost over current sugar purchased. We recommend that UBCFS and AMSFBD make a concerted effort to find an economically viable plan to convert their sugar purchases to organic fair-trade sugar.

The evolution of the Milky Way from its earliest phases : constraints on stellar nucleosynthesis

description: We computed the evolution of the abundances of O, Mg, Si, Ca, K, Ti, Sc, Ni, Mn, Co, Fe and Zn in the Milky Way. We made use of the most widely adopted nucleosynthesis calculations and compared the model results with observational data with the aim of imposing constraints upon stellar yields. In order to fit at best the data in the solar neighborhood, when adopting the Woosley and Weaver (1995) yields for massive stars and the Iwamoto et al. (1999) ones for type Ia SNe, it is required that: i) the Mg yields should be increased in stars with masses from 11 to 20 M_sun and decreased in masses larger than 20 M_sun. The Mg yield should be also increased in SNe Ia. ii) The Si yields should be slightly increased in stars above 40 M_sun, whereas those of Ti should be increased between 11 and 20 M_sun and above 30 M_sun. iii) The Cr and Mn yields should be increased in stars with masses in the range 11-20 M_sun, iv) the Co yields in SNe Ia should be larger and smaller in stars in the range 11-20 M_sun, v) the Ni yield from type Ia SNe should be decreased, vi) the Zn yield from type Ia SNe should be increased. vii) The yields of O (metallicity dependent SN models), Ca, Fe, Ni, and Zn (the solar abundance case) in massive stars from Woosley and Weaver (1995) are the best to fit the abundance patterns of these elements since they do not need any change. We adopted also the yields by Nomoto et al. (1997) and Limongi and Chieffi (2003) for massive stars and discussed the corrections required in these yields in order to fit the observations. Finally, the small spread in the [el/Fe] ratios in the metallicity range from [Fe/H]=-4.0 up to -3.0 dex (Cayrel et al. 2003) is a clear sign that the halo of the Milky Way was well mixed even in the earliest phases of its evolution.

Evidence for Tetrahedral Structure of Calcium-40
Creators: name: Manton, N. S.
Publisher: name: arXiv
Year: 2020
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: More than 100 excited states of the Calcium-40 nucleus, with isospin 0, are classified into rotational-vibrational bands of an intrinsic tetrahedral structure. Almost all observed states below 8 MeV can be accommodated, as well as many high-spin states above 8 MeV. The bands have some similarity to those classifying states of Oxygen-16, but the A-mode vibrational frequency is lower relative to the E-mode and F-mode frequencies than in Oxygen-16. Previously identified rotational bands up to spin 16 and energy above 20 MeV are unified here into a smaller number of tetrahedral bands.
