description: We study monotonicity and other properties of the canonical c-function (defined through the correlator of the energy-momentum tensor) in some holographic duals of 4-d quantum field theories. The canonical c-function and its derivatives are related to the 5-d Green's function of the dual supergravity theory. While positivity of the canonical c-function is obvious, we have not found a general proof of its monotonicity, even though c is monotonic in the few explicit examples we examine in this paper.

description: Despite widespread use of pneumococcal vaccines throughout Europe, the burden of pneumococcal disease (PD) in adults is considerable. To mitigate this burden, National Immunization Technical Advisory Groups (NITAGs) and Health Technology Assessment (HTA) agencies assess the value of different vaccine schedules for protecting against PD. The aim of this review was to assess the evidence and rationales used by NITAGs/HTA agencies, when considering recent changes to National Immunization Programs (NIPs) for adults, and how identified changes affected vaccine coverage rates (VCRs). A systematic review was conducted of published literature from PubMed® and Embase®, and gray literature from HTA/NITAG websites from the last 5 y, covering 31 European countries. Evidence related to NIP recommendations, epidemiology (invasive PD, pneumonia), health economic assessments and VCRs were collected and synthesized. Eighty-four records providing data for 26 countries were identified. Of these, eight described explicit changes to NIPs for adults in seven countries. Despite data gaps, some trends were observed; first, there appears to be a convergence of NIP recommendations in many countries toward sequential vaccination, with a pneumococcal conjugate vaccine (PCV), followed by pneumococcal polysaccharide vaccine 23. Second, reducing economic or healthcare burden were common rationales for implementing changes. Third, most health economic analyses assessing higher-valency PCVs for adults found its inclusion in NIPs cost-effective. Finally, higher coverage rates were seen in most cases where countries had expanded their NIPs to cover at-risk populations. The findings can encourage agencies to improve surveillance systems and work to reach the NIP’s target populations more effectively.

Gauge invariant generalization of the 2D chiral Gross-Neveu model

description: By means of the Lee-Shrock transformation we generalize the 2D Gross-Neveu (GN$_2$) model to a U(1) gauge theory with charged fermion and scalar fields in 2D ($χU ϕ_2$ model). The $χU ϕ_2$ model is equivalent to the GN$_2$ model at infinite gauge coupling. We show that the dynamical fermion mass generation and asymptotic freedom in the effective four-fermion coupling persist also when the gauge coupling decreases. These phenomena are not influenced by the XY$_2$ model phase transition at weak coupling. This suggests that the $χU ϕ_2$ model is in the same universality class as the GN$_2$ model and thus renormalizable.

Dynamical Mass of Type 2 Seyfert Nuclei

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

description: We have derived the masses of central objects ($M_{BH}$) of nine type 2 Seyfert nuclei using the observational properties of the hidden broad H$β$ emission. We obtain the average dynamical mass, log$(M_{BH} / M_\odot) \simeq 8.00 \pm 0.51 - 0.475 log (τ_{es}/1)$ where $τ_{es}$ is the optical depth for electron scattering. If $τ_{es} \sim 1$, this average mass is almost comparable with those of type 1 Seyfert nuclei. However, if $τ_{es} \ll 1$, as is usually considered, the average mass of type 2 Seyfert nuclei may be more massive than that of type 1s. We discuss implications for issues concerning both the current unified model of Seyfert nuclei and physical conditions of the electron scattering regions.

description: CAR-T cell therapy has demonstrated efficacy in treating certain hematological malignancies. However, the administration of CAR-T cells is accompanied by the occurrence of adverse events. Among these, cytokine release syndrome (CRS) has garnered significant attention. In this descriptive study, we set the search criteria to retrieve and obtain articles regarding CAR-T cell-related CRS from the Web of Science Core Collection (WoSCC). The bibliometric and knowledge-map analysis of these documents was conducted using Microsoft Excel 2019, GraphPad Prism 8, CtieSpace, and VOSviewer. 6,623 authors from 295 institutions in 49 countries coauthored a total of 1,001 publications. The leading country in this field was the United States. The most productive institution was the University of Pennsylvania. Carl H. June had the most citations, while Daniel W. Lee had the most co-citations. Research hotspots primarily concentrated on the pathogenesis, serum biomarkers, management, and therapeutic drugs of CRS, alongside neurotoxicity. Emerging topics within this discipline encompassed the following: a. Drugs for effective treatment and intervention of CRS; b. Conducting pertinent clinical trials to acquire real-world data; c. Management of toxicity (CRS and neurotoxicity) associated with CAR-T cell therapy; d. The study of BCMA-CAR-T cells in multiple myeloma (MM); e. Optimizing the CAR framework structure to enhance the effectiveness and safety of CAR-T cells. A bibliometric and scientific knowledge-map analysis provided a unique and objective perspective for exploring the field of CAR-T cell-related CRS, and may provide some new clues and valuable references for researchers.

description: This interview with W. A. Scott III begins with an overview his early life, including his family, education, and his service in Europe during World War II. The conversation the shifts to a discussion of Scott's career as circulation manager of the Atlanta Daily World, including the newspaper's circulation during his tenure. Also covered are the differences between black and white newspapers; changes in the black press over the years; the black press' successes and failures; and the decreasing frequency with which newspapers are published. W. A. Scott speaks about the impact of the transistor radio on the civil rights struggle; bias and objectivity in the press; and sensationalism in the black press; Scott's predictions for the future of the press in light of new technology; challenges he faced over the years; his interests apart from journalism; the ownership of black newspapers; the crusading spirit of the black press; and the prospects and necessity of a national black news service. The interview concludes with a discussion of whether the white press has become more fair and representative in coverage of minority affairs since the Kerner Commission report.

description: There is an interesting dichotomy between a space-time metric considered as external field in a flat background and the same considered as an intrinsic part of the geometry of space-time. We shall describe and compare two other external fields which can be absorbed into an appropriate redefinition of the geometry, this time a noncommutative one. We shall also recall some previous incidences of the same phenomena involving bosonic field theories. It is known that some such theories on the commutative geometry of space-time can be re-expressed as abelian-gauge theory in an appropriate noncommutative geometry. The noncommutative structure can be considered as containing extra modes all of whose dynamics are given by the one abelian action.

The Generalized Poisson distribution and a model of clustering from Poisson initial conditions
Creators: name: Sheth, Ravi K.
Publisher: name: arXiv
Year: 1998
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: This paper presents a new derivation of the Generalized Poisson distribution. This distribution provides a good fit to the evolved, counts-in-cells distribution measured in numerical simulations of hierarchical clustering from Poisson initial conditions. This new derivation can be used to construct a useful analytic model of the evolution of clustering measured in these simulations. The model is consistent with the assumption that, as the universe expands and the comoving sizes of regions change as a result of gravitational instability, the number of such expanding and contracting regions is conserved. The model neglects the influence of external tides on the evolution of such regions. Indeed, in the context of this model, the GPD can be thought of as arising from a simple variant of the well-studied spherical collapse model, in which tidal effects are also neglected. The model can be understood as a simple generalization of the excursion set model which is used to estimate the number density of collapsed, virialized halos. The generalization allows one to describe the spatial distribution of the halos and the mass simultaneously, so the extent to which these halos are biased tracers of the underlying matter distribution is easy to estimate.

A high-order lattice Boltzmann model for the Cahn-Hilliard equation

Subjects: subject: Computational Physics (physics.comp-ph)

description: In this paper, a lattice Boltzmann model with the single-relaxation-time model for the Cahn-Hilliard equation (CHE) is proposed. The discrete source term is redesigned through a third-order Chapman-Enskog analysis. By coupling the Navier-Stokes equations, the time-derivative term in the source term is expressed as the relevant spatial derivatives. Furthermore, the source term on the diffusive time scale is also proposed though recovering the macroscopic CHE to third order. The model is tested by simulating diagonal motion of a circular interface, Zalesak's disk rotation, circular interface in a shear flow and a deformation field. It is shown that the proposed method can track the interface with high accuracy and stability. For the complex flow, the source term on the diffusive time scale should be considered for capturing the interface correctly.

description: Although COVID-19 vaccination was approved for younger children in Japan in October 2022, uptake rates remain critically low. This study aimed to investigate Japanese parents’ intentions, hesitators’ probability of positive intention change, and factors that motivate COVID-19 vaccination. Parents with a 6-month to 4-year-old child living in Japan participated in this internet-based, cross-sectional survey conducted from December 19, 2022, to January 4, 2023. The modified Poisson regression analysis was used to assess the probabilities of changing intention by each motivator when comparing the degree of hesitancy among hesitators, and the Poisson generalized estimating equations were used to compare the probabilities of changing intentions by potential motivators within hesitant individuals. Among 12,502 participants, 10,008 (80.1%) were hesitators. Parents with lower hesitancy levels were more likely to be motivated to vaccinate their children through potential motivators. Vaccine hesitators were motivated to vaccinate their children, particularly by proven vaccine effectiveness (including “protecting children from getting sick” with a probability ratio [PR] of 3.7 [95% confidence interval (CI) 3.5–3.9] and “less likely to infect adults” with a PR of 2.9 [95% CI 2.8–3.1]), as well as vaccine safety (including “safe vaccination of millions of children” with a PR of 3.1 [95% CI 3.0–3.3]) compared to injunctive norm (including “community leader recommendation”). Therefore, initially addressing parents with low hesitancy levels is an effective strategy that motivates COVID-19 vaccination. Also, providing evidence-based information about COVID-19 vaccine efficacy and safety that is consistent with parents’ needs is crucial.

Investigating the role of TRPA1 and TRPV1 ion channels in the cough reflex
Creators: name: Grace, Megan Stacey
Publisher: name: Imperial College London
Year: 2011

description: Cough is under the control of sensory afferents which innervate the airways via the vagus nerve. Cough is an important protective reflex that clears the airway, but can become exacerbated and deleterious when associated with airways diseases, in which there is enhanced release of inflammatory mediators and a decrease in lung pH. These mediators sensitise airway afferents and could be driving enhanced cough associated with inflammation. Transient Receptor Potential (TRP) ion channels are associated with several disease pathologies. TRPV1 has an established role in cough, and is implicated in the aetiology of chronic cough; and TRPA1 is a promising new target. Involvement of these ion channels in the tussive reflex is awaiting comprehensive investigation. I have therefore explored the role of TRPA1 and TRPV1 in tussive responses to the endogenous irritants prostaglandin E2 (PGE2), bradykinin (BK) and low pH. To do this I have used selective antagonists and genetically modified mice in models of human, guinea pig and mouse vagal sensory nerve depolarisation; conscious guinea pig cough; and guinea pig primary ganglia cell imaging. TRPA1 and TRPV1 were shown to mediate PGE2 and BK-induced nerve depolarisation, cough, and activation of ganglia cells. In contrast, low pH-induced nerve depolarisation and ganglia cell activation was mediated via TRPV1 or Acid Sensing Ion Channels (ASICs); whereas, cough was partially attenuated with TRPA1 or TRPV1 antagonists. In summary, I have identified that TRPA1 and TRPV1 mediate PGE2 and BK-induced cough; and provided evidence that low pH-induced sensory nerve activation is mediated via TRPV1 and ASICs, but a role for TRPA1 is still unclear. These are exciting findings which add to our understanding of the mechanisms that drive the cough reflex in the healthy state; builds a base for investigating cough hypersensitivity in disease; and could help to guide the development of novel efficacious anti-tussive therapies.

description: We discuss the quantum-mechanical scattering of a massless scalar field on a $δ$-potential in a ghost-free theory and obtain analytic solutions for the scattering coefficients. Due to the non-locality of the ghost-free theory the transmission coefficient tends to unity for frequencies much larger than the inverse scale of non-locality, even for infinitely strong potentials. At the same time there exists a critical strength of the $δ$-potential barrier below which there is always a frequency that is totally reflected. These scattering properties in ghost-free theories are quite generic and distinguish them from local field theories. Moreover, we study quasi-normal states that are present for the $δ$-potential well. In the limit of vanishing non-locality, we recover the standard results of local field theory.

description: While cars were only considered as means of personal transportation for a long time, they are currently transcending to mobile sensor nodes that gather highly up-to-date information for crowdsensing-enabled big data services in a smart city context. Consequently, upcoming 5G communication networks will be confronted with massive increases in Machine-type Communication (MTC) and require resource-efficient transmission methods in order to optimize the overall system performance and provide interference-free coexistence with human data traffic that is using the same public cellular network. In this paper, we bring together mobility prediction and machine learning based channel quality estimation in order to improve the resource-efficiency of car-to-cloud data transfer by scheduling the transmission time of the sensor data with respect to the anticipated behavior of the communication context. In a comprehensive field evaluation campaign, we evaluate the proposed context-predictive approach in a public cellular network scenario where it is able to increase the average data rate by up to 194% while simultaneously reducing the mean uplink power consumption by up to 54%.

Investigating the relationship between magnetisation and oil geochemistry
Creators: name: Emmerton, Stacey Anne
Publisher: name: Imperial College London
Year: 2013

description: A relationship between hydrocarbons and their magnetic signatures has previously been alluded to but this is the first study to combine extensive geochemical and magnetic data of hydrocarbon-associated samples. A detailed study is reported that identifies a definitive connection between magnetic mineralogy and oil biodegradation within samples from Colombia, Canada, Indonesia and the UK. Geochemical data revealed that all the oil samples were derived from mature type-II kerogen deposited in oxygen-poor environments allowing for an investigation into biodegradation. Biodegradation is the decrease of oil quality through the conversion of aliphatic hydrocarbons to polar constituents through the activity of bacteria. The percentage of oil components and the biodegradation state of the samples were compared to the magnetic susceptibility and magnetic mineralogy. A distinct decrease in magnetic susceptibility was correlated to decreasing oil quality as well as extractable organic matter percentages, which cannot be rejected at 99% confidence. Further magnetic characterisation revealed that the high quality oils were dominated by pseudo-single domain grains of magnetite and the lower quality oils by larger pseudo-single domain to multi domain grains of magnetite and hematite; with decreasing oil quality there is a progressive dominance of multi domain magnetite as well as the appearance of hematite. It is concluded that biodegradation is a dual process, firstly, removing aliphatic hydrocarbons reducing oil quality and secondly, both creating and destroying magnetic signatures. This complex relationship may explain why controversy existed in the past when studying hydrocarbon associated anomalies. Remagnetisation due to hydrocarbon infiltration is also reported within the Wessex Basin, UK. Palaeodirectional data from Mupe Bay revealed oil migration was initiated in the Early Cretaceous and a two-phase staining model is correct. These findings reinforce the importance of bacteria within petroleum systems as well as providing a platform for the use of magnetisation as a hydrocarbon proxy.

In the 't Hooft limit, the equation reduces to the loop equation of ordinary Yang-Mills theory. At finite $N$, the equation involves the quantum averages of the additional gauge invariant observables of the non-commutative theory associated with open contours in space-time. We also derive equations for correlators of several gauge invariant (open or closed) Wilson lines. Finally, we discuss a perturbative check of our results.

description: The deformation retract is, by definition, a homotopy between a retraction and the identity map. We show that applying this topological concept to Ricci-flat wormholes/black holes implies that such objects can get deformed and reduced to lower dimensions. The homotopy theory can provide a rigorous proof to the existence of black holes/wormholes deformations and explain the topological origin. The current work discusses such possible deformations and dimensional reductions from a global topological point of view, it also represents a new application of the homotopy theory and deformation retract in astrophysics and quantum gravity.

description: In this paper, we report efficient quantum circuits for integer multiplication using Toom-Cook algorithm. By analysing the recursive tree structure of the algorithm, we obtained a bound on the count of Toffoli gates and qubits. These bounds are further improved by employing reversible pebble games through uncomputing the intermediate results. The asymptotic bounds for different performance metrics of the proposed quantum circuit are superior to the prior implementations of multiplier circuits using schoolbook and Karatsuba algorithms.

description: For faint photometric surveys our ability to quantify the clustering of galaxies has depended on interpreting the angular correlation function as a function of the limiting magnitude of the data. Due to the broad redshift distribution of galaxies at faint magnitude limits the correlation signal has been extremely difficult to detect and interpret. We introduce a new technique for measuring the evolution of clustering. We utilize photometric redshifts, derived from multicolor surveys, to isolate redshift intervals and calculate the evolution of the amplitude of the angular 2-pt correlation function. Applying these techniques to the the Hubble Deep Field we find that the shape of the correlation function, at z=1, is consistent with a power law with a slope of -0.8. For z>0.4 the best fit to the data is given by a model of clustering evolution with a comoving r0 = 2.37 Mpc and eps = -0.4 +/- 0.5, consistent with published measures of the clustering evolution. To match the canonical value of r0 = 5.4 Mpc, found for the clustering of local galaxies, requires a value of eps = 2.10 +/- 0.5 (significantly more than linear evolution). The log likelihood of this latter fit is 4.15 less than that for the r0 = 2.37 Mpc model. We, therefore, conclude that the parameterization of the clustering evolution of (1+z)^-(3+eps) is not a particularly good fit to the data.

description: The free energy landscape responsible for crystallization can be complex even for relatively simple systems like hard sphere and charged stabilized colloids. In this work, using hard-core repulsive Yukawa model, which is known to show complex phase behavior consisting of fluid, FCC and BCC phases, we studied the interplay between the free energy landscape and polymorph selection during crystallization. When the stability of the BCC phase with respect to the fluid phase is gradually increased by changing the temperature and pressure at a fixed fluid-FCC stability, the final phase formed by crystallization is found to undergo a switch from the FCC to the BCC phase, even though FCC remains thermodynamically the most stable phase. We further show that the nature of local bond-orientational order parameter fluctuations in the metastable fluid phase as well as the composition of the critical cluster depend delicately on the free energy landscape, and play a decisive role in the polymorph selection during crystallization.

Forward genetic analysis of memory CD8+ T lymphocyte development and long-term maintenance by in vivo chemical germline mutagenesis

description: The establishment and long-term maintenance of virus-specific memory CD8+ cytotoxic T lymphocytes (CTL) is genetically controlled. However, not all genes involved in this process have been identified in vivo to date and their identity and function have to be clarified. To identify novel genes which regulate the development of memory cells, we have undertaken an in vivo forward genetic approach based on germline mutagenesis screening. Random point mutations were introduced in the genome of wild-type mice by N-ethyl-N-nitrosourea (ENU) treatment. A library of third generation mutants was then screened for genetic defects affecting their immune responses to Lymphocytic Choriomeningitis virus (LCMV). Altered immune responses to LCMV in mutant mice were detected by measuring the percentage of antigen-specific CTL, their cell death and the composition of the LCMVspecific CD8+ T cell pool at the peak of expansion and at the beginning of the memory phase. Any individuals with outstanding cell population numbers or characteristics were isolated as phenodeviants. Once a mutation was confirmed to affect the germline, a stable strain was established and the mutation was mapped by positional cloning. Through this process, we have isolated 3 mutants: memi, binu and alois. Our first mutant, memi was isolated based on its very low CD8+ T cell memory population following LCMV infections. Using single nucleotide polymorphism linkage analysis, we identified memi as a loss-of-function mutation in the gene encoding deoxycytidine kinase (dCK), a crucial enzyme of the nucleoside salvage pathway. In addition to the immunological phenotype observed after viral infection, we have characterized significant changes in T and B lymphocyte development and their cell-intrinsic/extrinsic peripheral homeostasis in naive memi mice. This mutant is valuable especially to understand how a defect in nucleoside salvage impacts on lymphocyte development and behaviour. The other two mutants, binu and alois, which present increased and decreased CD8+ T memory precursors upon LCMV infection, respectively, are currently being mapped. To our knowledge, no mutant with exactly the same phenotypes as binu or alois has been described to date and we therefore believe that they have strong potential to be novel mutants. Overall, our ENU mutagenesis was successful both in terms of the number of mutants we have isolated and the types of mutations they represent, affecting known and potential new immune regulators.

description: In India, to achieve the stringent norms of total nitrogen less than 10 mg/l in sewage treatment plant is a big challenge for the public - private facilities and organizations. After successful implementation of this norm the pollutant burden from rivers and natural water bodies certainly reduces. The use of conventional biological nitrogen removal (BNR) processes for new treatment facility development or retrofitting is also an energy and cost intensive practice. The process technologies offered by current market such as MLE, MBBR, IFAS and SBR are still in with downside of higher footprint, multi tank reactors, heavy instrumentation for IR and RAS which ultimately incur higher capital and operating cost. The current market need and lack of sustainable nitrogen removal applications, trigger to review the of all available efficient biological nitrogen removal processes. This review will gives an overall scenario of past and current biological nitrogen removal process technologies with showing possible scope and way forward towards more energy neutral nitrogen removal technologies.

description: We develop an improved sky background estimator which employs optimal filters for both spatial and pixel intensity distributions. It incorporates growth of masks around detected objects and a statistical estimate of the flux from undetected faint galaxies in the remaining sky pixels. We test this algorithm for underlying sky estimation and compare its performance with commonly used sky estimation codes on realistic simulations which include detected galaxies, faint undetected galaxies, and sky noise. We then test galaxy surface brightness recovery using GALFIT 3, a galaxy surface brightness profile fitting optimizer, yielding fits to Sérsic profiles. This enables robust sky background estimates accurate at the 4 parts-per-million level. This background sky estimator is more accurate and is less affected by surface brightness profiles of galaxies and the local image environment compared with other methods.
