Subjects: subject: Fluid Dynamics (physics.flu-dyn)
subject: FOS: Physical sciences

description: When a solid plate is withdrawn from a partially wetting liquid, a liquid layer dewets the moving substrate. High-speed imaging reveals alternating thin and thick regions in the entrained layer in the transverse direction at steady state. This paper systematically compares this situation to the reversed process, forced wetting, where a solid entrains an air layer along its surface as it is pushed into a liquid. To quantify the absolute thickness of these steady-state structures precisely, I have developed an optical technique, taking advantage of the angle dependence of interference, combined with a method based on a maximum likelihood estimation. The data show that the thicknesses of both regions of the film scale with the capillary number, Ca. In addition, a new region is observed during onset which differs from the behavior predicted by previous models.

description: This article documents one of the world's first standards-compliant pre-commercial end-to-end 5th generation (5G) systems. Focus is on a standardized 5G architecture which includes the underlying 3GPP components but also the ETSI Network Function Virtualization (NFV) management and orchestration capabilities. The truly innovative character of 5G enabling fundamental changes to architecture and implementation is discussed, and details of monitoring and orchestration approaches that are deemed instrumental in unlocking the full potential of 5G. Finally, it is important to us to share the lessons learned which we hope are of use to industry and academia alike when building, deploying and testing emerging 5G systems.
Global oscillations of a fluid torus as a modulation mechanism for black-hole high-frequency QPOs

Subjects: subject: Astrophysics (astro-ph)

description: We study strong-gravity effects on modulation of radiation emerging from accreting compact objects as a possible mechanism for flux modulation in QPOs. We construct a toy model of an oscillating torus in the slender approximation assuming thermal bremsstrahlung for the intrinsic emissivity of the medium and we compute observed (predicted) radiation signal including contribution of indirect (higher-order) images and caustics in the Schwarzschild spacetime. We show that the simplest oscillation mode in an accretion flow, axisymmetric up-and-down motion at the meridional epicyclic frequency, may be directly observable when it occurs in the inner parts of accretion flow around black holes. Together with the second oscillation mode, an in-and-out motion at the radial epicyclic frequency, it may then be responsible for the high-frequency modulations of the X-ray flux observed at two distinct frequencies (twin HF-QPOs) in micro-quasars.

description: The CTR (Click-Through Rate) prediction plays a central role in the domain of computational advertising and recommender systems. There exists several kinds of methods proposed in this field, such as Logistic Regression (LR), Factorization Machines (FM) and deep learning based methods like Wide&Deep, Neural Factorization Machines (NFM) and DeepFM. However, such approaches generally use the vector-product of each pair of features, which have ignored the different semantic spaces of the feature interactions. In this paper, we propose a novel Tensor-based Feature interaction Network (TFNet) model, which introduces an operating tensor to elaborate feature interactions via multi-slice matrices in multiple semantic spaces. Extensive offline and online experiments show that TFNet: 1) outperforms the competitive compared methods on the typical Criteo and Avazu datasets; 2) achieves large improvement of revenue and click rate in online A/B tests in the largest Chinese App recommender system, Tencent MyApp.

Word processors and the teaching of written composition : a study of high school English teachers’ attitudes, perceptions, and experiences
Creators: name: Crescenzi, Patrizia
Publisher: name: University of British Columbia
Year: 2009

description: In 1989, Herrmann reported that the lack of computer use in schools is not because the schools are not purchasing computers, but because computers "...in classes, such as English, ... are not being used as effectively as they might be" (p. 112). Thus, this current thesis is a relational study that sought to understand how high school English teachers' attitudes towards, perceptions of, and experiences with computers affected their reported implementation of word processors in the teaching of written composition. The findings of this study were based on the results of 52 surveys completed by high school English teachers teaching in a large urban centre. The survey was a combination of multiple-choice, Likert-scale, and open-ended questions and the data were analysed to note relationships between and trends among variables. Ninety percent of the respondents reported spending no time teaching written composition with a word processor, and only 3% of the respondents said they felt confident in their ability to integrate computers into the teaching of written composition. Further data analysis indicated that these teachers exhibited varying and conflicting attitudes, perceptions, and experiences. Teachers' "Readiness to Implement" (i.e., their willingness to receive word processors in the classroom and some self-reports of present computer-related practices) produced the strongest correlation with "Current Practice" (e.g., teaching the writing process and using the word processor to teach pre-writing, drafting, revising, and editing), while "Attitude," "Perception," and "Professional Development Experience" showed limited and localized effects (correlating with some gender, age, or years of experience groups and not others). Consistent with the findings of previous studies, only negligible differences were noted between male and female respondents. However, the two respondents over the age of 60 scored higher (M =4.4) on the "Attitude" scale than their junior colleagues, and the one respondent with 0-1 year of experience scored lower (M = 2.0) than her colleagues with more English-Language Arts teaching experience. Respondents in this study reported a limited amount of access to computer labs and a weak infrastructure for supporting implementation.
A quintessence dynamical dark energy model from ratio gravity

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: Based on the work of ratio gravity developed in 2018, which postulates the deformation of the cross ratio to associate with the physical model of gravity, we develop a mechanism to generate dynamical dark energy - a quintessence field coupled with gravity. Such model causes the dark energy behaving differently in early and late time universe. In the radiation-dominated-era and matter-dominated-era, the related analytical solutions of the quintessence field have an interesting property - starting as a constant field, then oscillating as the universe expands. By Markov Chain Monte Carlo search of the parameter space with the local measurement (Type Ia supernovae) in the Bayesian framework, the probed range of {H_0} (within 1σ) overlaps the {H_0} value inferred from Planck CMB dataset by ΛCDM model.

description: We study the $T\bar{T}$ deformation of the chiral bosons and show the equivalence between the chiral bosons of opposite chiralities and the scalar fields at the Hamiltonian level under the deformation. We also derive the deformed Lagrangian of more generic theories which contain an arbitrary number of chiral bosons to all orders. By using these results, we derive the $T\bar{T}$ deformed boundary action of the AdS$_3$ gravity theory in the Chern-Simons formulation. We compute the deformed one-loop torus partition function, which satisfies the $T\bar{T}$ flow equation up to the one-loop order. Finally, we calculate the deformed stress tensor of a solution describing a BTZ black hole in the boundary theory, which coincides with the boundary stress tensor derived from the BTZ black hole with a finite cutoff.

description: In this paper we simulate a real biometric verification system based on on-line signatures. For this purpose we have split the MCYT signature database in three subsets: one for classifier training, another for system adjustment and a third one for system testing simulating enrollment and verification. This context corresponds to a real operation, where a new user tries to enroll an existing system and must be automatically guided by the system in order to detect the failure to enroll situations. The main contribution of this work is the management of failure to enroll situations by means of a new proposal, called intelligent enrollment, which consists of consistency checking in order to automatically reject low quality samples. This strategy lets to enhance the verification errors up to 22% when leaving out 8% of the users. In this situation 8% of the people cannot be enrolled in the system and must be verified by other biometrics or by human abilities. These people are identified with intelligent enrollment and the situation can be thus managed. In addition we also propose a DCT-based feature extractor with threshold coding and discriminability criteria.

Perturbative renormalization of the lattice regularized $ϕ_4^4$ with flow equations
Creators: name: Borji, Majdouline

Publisher: name: arXiv
Year: 2020
Subjects: subject: Mathematical Physics (math-ph)
subject: FOS: Physical sciences

description: The flow equations of the renormalization group allow to analyse the perturbative $n$-point functions of renormalizable quantum filed theories. Rigorous bounds implying renormalizability permit to control large momentum behaviour, infrared singularities and large order behaviour in the number of loops and the number of arguments $n$. In this paper, we analyse the Euclidean $4$-dimensional massive $ϕ_4$-theory using lattice regularization. We present a rigorous proof that this quantum field theory is renormalizable, to all orders of the loop expansion based on the flow equations. The lattice is known to break the Euclidean symmetry of the space-time. Our main result is the proof of the restoration of the Euclidean symmetries using the flow equations.

description: Numerical simulations have revealed a new type of turbulence of unidirectional waves in a plasma that is perpendicularly structured (Magyar et al. 2017), named uniturbulence. For this new type of turbulence, the transverse structuring modifies the upward propagating wave to have both Elsasser variables, leading to the well-known perpendicular cascade. In this paper, we study an analytical description of the non-linear evolution of kink waves in a cylindrical flux tube, which are prone to uniturbulence. We show that they lead to a non-linear cascade for both propagating and standing waves. We calculate explicit expressions for the wave pressure and energy cascade rate. The computed damping rate τ/P depends on the density contrast of the flux tube and the background plasma and is inversely proportional to the amplitude of the kink wave. The dependence on the density contrast shows that it plays a role especially in the lower solar corona. These expressions may be added in Alfven wave driven models of the solar atmosphere (such as AWSOM, van der Holst et al. 2014), modifying it to UAWSOM (Uniturbulence and Alfven Wave Solar Model).

These solutions in general are neither stationary nor self-similar.

description: The effect that selected characteristics of a Pennsylvania hay auction has on winning bids of loads of hay are presented in this paper. Survey data from 107 buyers over the period September 1982 to April 1983 were used. Hay type, perceived quality, and the intended use of the hay were found to be significant factors in explaining prices paid per ton. Sellers could increase their revenues by producing alfalfa hay, alfalfa and legume-grass hay of higher quality, and attending marketing days with a larger number of horse feed buyers.
Search for long-lived heavy neutral leptons with the CMS experiment using machine learning techniques
Creators: name: Dancu, Julia-Suzana
Publisher: name: Imperial College London
Year: 2023

description: This Thesis presents the analysis strategies and outcomes of a search looking for long-lived Heavy Neutral Leptons (HNLs) in proton-proton collision data corresponding to 137fb$^{-1}$ integrated luminosity, collected by the CMS experiment at the Large Hadron Collider with $\sqrt{s}=13$ TeV. The HNL particles are searched for via charged-current production and semi-leptonic decay mode into a lepton and jet that can be displaced from the primary collision point. A fine-grained event categorisation scheme ensures enhanced sensitivity to a number of HNL benchmark models including both Dirac- and Majorana-type particles. The search employs a novel deep neural network-based displaced jet tagger and a complementary event-level boosted decision tree algorithm with the aim of separating HNL signal events from Standard Model (SM) background processes. The blinded analysis uses a data-driven background estimation method to evaluate the expected yields, the method being validated in two control regions. After unblinding, no excess of events was found and upper limits on the HNL production cross-section were set for a broad range of HNL mass, lifetime and coupling scenarios, including universal mixing with all SM lepton generations. A particular focus of this Thesis was the evaluation of displaced lepton reconstruction and identification of scale factors, which were found to be one of the dominant systematic uncertainties associated with the signal interpretation. The results presented in this Thesis are competitive with previously published similar searches in high energy physics and are the first in the CMS collaboration to consider arbitrary coupling combinations involving all three SM lepton generations.

description: We extend the recently developed treatment of baryon resonances in large N_c QCD to describe resonance multiplets collected according to the SU(3) flavor symmetry that includes strange quarks. As an illustration we enumerate the SU(3) partners of a hypothetical J^P = 1/2^{+/-} resonance in the SU(3) representation that reduces to 10-bar when N_c = 3, and reproduce results hitherto obtained only in the context of a large N_c quark picture. While these specific quantum numbers represent one favored set for the possible pentaquark state Theta^+ (1540), the method is applicable to baryon resonances with any quantum numbers.

Proper identification of RR Lyrae Stars brighter than 12.5 mag

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

description: RR Lyrae stars are of great importance for investigations of Galactic structure. However, a complete compendium of all RR-Lyraes in the solar neighbourhood with accurate classifications and coordinates does not exist to this day. Here we present a catalogue of 561 local RR-Lyrae stars V_max less equal 12.5 mag according to the magnitudes given in the Combined General Catalogue of Variable Stars (GCVS) and 16 fainter ones. The Tycho2 catalogue contains about 100 RR Lyr stars. However, many objects have inaccurate coordinates in the GCVS, the primary source of variable star information, so that a reliable cross-identification is difficult. We identified RR Lyrae from both catalogues based on an intensive literature search. In dubious cases we carried out photometry of fields to identify the variable. Mennessier and Colome (2002) have published a paper with Tyc2-GCVS identifications, but we found that many of their identifications are wrong.

description: The detection of negative emotions through daily activities such as handwriting is useful for promoting well-being. The spread of human-machine interfaces such as tablets makes the collection of handwriting samples easier. In this context, we present a first publicly available handwriting database which relates emotional states to handwriting, that we call EMOTHAW. This database includes samples of 129 participants whose emotional states, namely anxiety, depression and stress, are assessed by the Depression Anxiety Stress Scales (DASS) questionnaire. Seven tasks are recorded through a digitizing tablet: pentagons and house drawing, words copied in handprint, circles and clock drawing, and one sentence copied in cursive writing. Records consist in pen positions, on-paper and in-air, time stamp, pressure, pen azimuth and altitude. We report our analysis on this database. From collected data, we first compute measurements related to timing and ductus. We compute separate measurements according to the position of the writing device: on paper or in-air. We analyse and classify this set of measurements (referred to as features) using a random forest approach. This latter is a machine learning method [2], based on an ensemble of decision trees, which includes a feature ranking process. We use this ranking process to identify the features which best reveal a targeted emotional state. We then build random forest classifiers associated to each emotional state. Our results, obtained from cross-validation experiments, show that the targeted emotional states can be identified with accuracies ranging from 60% to 71%.

description: We study the decay of the $Z$ vector boson into a photon and a massless (invisible) dark photon in high-energy collisions. The photon can be used as trigger for the event, while the dark photon is detected indirectly as missing momentum in the event final state. We investigate the possibility of searching for such a dark photon at the LHC, HL-LHC and future lepton colliders, and compare the respective sensitivities. As expected, the best result is found for the lepton colliders running at the $Z$ mass, FCC-ee and CEPC, with a final sensitivity to branching ratios of order $O(10^{-11})$. We also discuss how to use the photon angular distribution of the events in lepton collisions to discriminate between the dark photon and a pseudo-scalar state like the axion.

description: We describe the concept of a dry electrode sensor for biopotential measurement applications (ENOBIO) designed to eliminate the noise and inconvenience associated to the use of electrolytic gel. ENOBIO uses nanotechnology to remove gel-related noise, as well as maintaining a good contact impedance to minimise interference noise. The contact surface of the electrode will be covered with an array/forest of carbon nanotubes and will also be tested with an Ag/AgCl coating to provide ionic-electronic transduction. The nanotubes are to penetrate the outer layers of the skin, the Stratum Corneum, improving electrical contact. We discuss requirements, skin properties, nanotube penetration and transduction, noise sources, prototype design logic and biocompatibility. A future paper will report test results.

description: We present new 450 and 850 micron SCUBA data and 1.3 mm MAMBO data of the dwarf galaxies II Zw 40, He 2-10 and NGC 1140. Additional ISOCAM, IRAS as well as ground based data are used to construct the observed mid-infrared to millimeter spectral energy distribution of these galaxies. These spectral energy distributions are modeled in a self-consistent way, as was achieved with NGC 1569 (Galliano et al., 2003), synthesizing both the global stellar radiation field and the dust emission, with further constraints provided by the photoionisation of the gas. Our study shows that low-metallicity galaxies have very different dust properties compared to the Galaxy. Our main results are: (i) a paucity of PAHs which are likely destroyed by the hard penetrating radiation field, (ii) a very small (3-4 nm) average size of grains, consistent with the fragmentation and erosion of dust particles by the numerous shocks, (iii) a significant millimetre excess in the dust spectral energy distribution which can be explained by the presence of ubiquitous very cold dust (T=5-9 K) accounting for 40 to 80 % of the total dust mass, probably distributed in small clumps. We derive a range of gas-to-dust mass ratios between 300 and 2000, larger than the Galactic values and dust-to-metals ratios of 1/30 to 1/2. The modeled dust size distributions are used to synthesize an extinction curve for each galaxy. The UV slopes of the extinction curves resemble that observed in some regions in the Large Magellanic Cloud. The 2175 angstrom bumps of the modeled extinction curves are weaker than that of the Galaxy, except in the case of II Zw 40, where we are unable to accurately constrain the 2175 angstrom bump carrier.

description: Fragments productions in spallation reactions are key infrastructure data for various applications. Based on the empirical parameterizations {\sc spacs}, a Bayesian-neural-network (BNN) approach is established to predict the fragment cross sections in the proton induced spallation reactions. A systematic investigation have been performed for the measured proton induced spallation reactions of systems ranging from the intermediate to the heavy nuclei and the incident energy ranging from 168 MeV/u to 1500 MeV/u. By learning the residuals between the experimental measurements and the {\sc spacs} predictions, the BNN predicted results are in good agreement with the measured results. The established method is suggested to benefit the related researches in the nuclear astrophysics, nuclear radioactive beam source, accelerator driven systems, and proton therapy, etc.

description: One option for the disposal of sewage sludge is land spreading, including application to private croplands. Land spreading may allow some of the sewage treatment costs to the municipality or county to be offset by farmers' payments for sludge as a crop producing resource. This study investigates the conditions under which a market for sludge will emerge. A linear programming model of a profit maximizing corn for gain farm is formulated and the quantity of sludge available is parametrically varied to trace out marginal productivity curves under various situations. The results for Anne Arundel county, Maryland sludge show a range in value from 0-35 $/ton at application rates from 0-20 tons/acre/year for three years.

description: A survey of agricultural banks in New York State found that inability to compete with the low interest rates offered by the Farm Credit Service (FCS) rather than the unavailability of funds per se was limiting agricultural lending by commercial banks. A MASI-like intermediary would (1) be of assistance only to banks unable to use loan participations and with high CD costs and (2) would likely require a large multistate area to be feasible. Only eight percent of the New York banks serving agriculture qualify for FICB funding. Further, FICB funding would be profitable only if banks experienced illiquidity at least 50 percent of the time.

description: This paper examines the acquisition of wood stoves by New Hampshire households through use of a utility-maximizing discrete choice model. The analysis is based on the hypothesis that wood stoves are acquired to decrease the monetary costs of home-heating. Operating costs associated with heating with conventional fuel burning capital and with a combination of conventional and wood stove heating capital are estimated. These operating costs are used to estimate probabilities of 1979 wood stove acquisition for particular types of New Hampshire households.

The stationary probability density function of polymer extension is derived exactly. The characteristic time needed for the system to attain the stationary regime is computed as a function of the Weissenberg number and the maximum length of polymers. The transient relaxation to the stationary regime is predicted to be exceptionally slow in the proximity of the coil-stretch transition.

description: Researchers and decision makers are currently faced with a reduced supply of agricultural marketing information at both federal and state levels. Although a number of on-line computer informational sources are available to help fill this gap, the data are relatively expensive and often not available in the form or detail needed at the farm level. This paper examines expected future sources of agricultural information in the public, private and semi-public/private sectors. A working model of a semi-public/private informational system is presented. The proposed self-help grower informational model system can be tailored to provide farm level data needed at a reasonable cost.

description: Within the framework of field-theoretical description of second-order phase transitions via the 3-dimensional O(N) vector model, accurate predictions for critical exponents can be obtained from (resummation of) the perturbative series of Renormalization-Group functions, which are in turn derived --following Parisi's approach-- from the expansions of appropriate field correlators evaluated at zero external momenta. Such a technique was fully exploited 30 years ago in two seminal works of Baker, Nickel, Green and Meiron, which lead to the knowledge of the $β$-function up to the 6-loop level; they succeeded in obtaining a precise numerical evaluation of all needed Feynman amplitudes in momentum space by lowering the dimensionalities of each integration with a cleverly arranged set of computational simplifications. In fact, extending this computation is not straightforward, due both to the factorial proliferation of relevant diagrams and the increasing dimensionality of their associated integrals; in any case, this task can be reasonably carried on only in the framework of an automated environment. On the road towards the creation of such an environment, we here show how a strategy closely inspired by that of Nickel and coworkers can be stated in algorithmic form, and successfully implemented on the computer. As an application, we plot the minimized distributions of residual integrations for the sets of diagrams needed to obtain RG-functions to the full 7-loop level; they represent a good evaluation of the computational effort which will be required to improve the currently available estimates of critical exponents.

description: Human-robot interaction is becoming an interesting area of research in cognitive science, notably, for the study of social cognition. Interaction theorists consider primary intersubjectivity a non-mentalist, pre-theoretical, non-conceptual sort of processes that ground a certain level of communication and understanding, and provide support to higher-level cognitive skills. We argue this sort of low level cognitive interaction, where control is shared in dyadic encounters, is susceptible of study with neural robots. Hence, in this work we pursue three main objectives. Firstly, from the concept of active inference we study primary intersubjectivity as a second person perspective experience characterized by predictive engagement, where perception, cognition, and action are accounted for an hermeneutic circle in dyadic interaction. Secondly, we propose an open-source methodology named \textit{neural robotics library} (NRL) for experimental human-robot interaction, and a demonstration program for interacting in real-time with a virtual Cartesian robot (VCBot). Lastly, through a study case, we discuss some ways human-robot (hybrid) intersubjectivity can contribute to human science research, such as to the fields of developmental psychology, educational technology, and cognitive rehabilitation.

description: It is proposed that supersymmetry (SUSY) maybe used to understand fermion mass hierarchies. A family symmetry Z_{3L} is introduced, which is the cyclic symmetry among the three generation SU(2) doublets. SUSY breaks at a high energy scale ~ 10^{11} GeV. The electroweak energy scale ~ 100 GeV is unnaturally small. No additional global symmetry, like the R-parity, is imposed. The Yukawa couplings and R-parity violating couplings all take their natural values which are about (10^0-10^{-2}). Under the family symmetry, only the third generation charged fermions get their masses. This family symmetry is broken in the soft SUSY breaking terms which result in a hierarchical pattern of the fermion masses. It turns out that for the charged leptons, the tau mass is from the Higgs vacuum expectation value (VEV) and the sneutrino VEVs, the muon mass is due to the sneutrino VEVs, and the electron gains its mass due to both Z_{3L} and SUSY breaking. The large neutrino mixing are produced with neutralinos playing the partial role of right-handed neutrinos. |V_{e3}| which is for nu_e-nu_{tau} mixing is expected to be about 0.1. For the quarks, the third generation masses are from the Higgs VEVs, the second generation masses are from quantum corrections, and the down quark mass due to the sneutrino VEVs. It explains m_c/m_s, m_s/m_e, m_d > m_u and so on. Other aspects of the model are discussed.

description: We propose a novel double-entanglement-based quantum cryptography protocol that is both efficient and deterministic. The proposal uses photon pairs with entanglement both in polarization and in time degrees of freedom; each measurement in which both of the two communicating parties register a photon can establish one and only one perfect correlation and thus deterministically create a key bit. Eavesdropping can be detected by violation of local realism. A variation of the protocol shows a higher security, similarly to the six-state protocol, under individual attacks. Our scheme allows a robust implementation under current technology.

description: Measurements of identified particle production with the PHENIX experiment at RHIC have reached a mature state, where a multitude of nuclear systems at different colliding energies have been studied. The discovery configurations of $\sqrt{s_{NN}}$ = 130 and 200 GeV Au+Au collisions have now been supplemented by additional Au+Au and Cu+Cu configurations at various energies, along with baseline p+p and d+Au runs at $\sqrt{s_{NN}}$ = 200 GeV. In this work we present a systematic study of the Cronin effect in d+Au collisions and recent results from p+p collisions. We then proceed to make a critical comparison of pion, kaon and proton production in heavy ion and baseline systems, and discuss the observed nuclear effects on hadron production.

The targum (1953:May 1 - 1953:May 12)
Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1953

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.
Taurine metabolism is associated with inflammasome activation via the taurine transporter
Creators: name: Rossi-Smith, Pedro
Publisher: name: Imperial College London

description: The intersection of immunology and metabolism, known as immunometabolism, explores the interactions between immune responses and metabolic changes. Inflammasomes form an integral part of the innate immune system and are equipped with NLR or ALR receptors capable of detecting a wide array of stimuli triggered by infections or cellular damage. Upon activation, these inflammasomes are involved in the release of inflammatory cytokines and can trigger a regulated type of cell death known as pyroptosis. Like other immune responses, inflammasome activation also induces changes in metabolic pathways such as the tricarboxylic acid (TCA) cycle. However, the role of other metabolic pathways in response to activation of inflammasomes remains less explored. Here, by employing a metabolomic approach on murine macrophages, I found that activation of inflammasomes (NLRP3, AIM2 or NLRC4) induced metabolic shifts not only within the TCA cycle, but also extends its impact to sulphur metabolism. Furthermore, through a rigorous cross-species analysis that compared human and mouse responses, I uncovered a notable downregulation of taurine metabolism following NLRP3 activation. This intriguing discovery highlighted a conserved regulatory mechanism and identified intracellular depletion of taurine and hypotaurine as a putative checkpoint in NLRP3 activation pathway. Using two distinct approaches, a direct supplementation of taurine or hypotaurine, and inhibition of taurine transporter prior to NLRP3 activation, showed a significant decrease in IL-1β release in a caspase-1 independent manner. The clinical significance of these findings was underlined by the observation of a similar downregulation of taurine metabolism in individuals affected by tuberculosis-associated immune reconstitution inflammatory syndrome, which is known to be inflammasome-driven. This convergence of in vitro observations with clinical data further emphasizes the importance of inflammasome-mediated metabolic alterations and their potential impact on disease pathogenesis. These findings hold considerable potential for guiding future research aimed at unravelling the intricate cross-talk between inflammation and metabolism, with far-reaching implications for the design of targeted therapeutic strategies to counter aberrant inflammasome activation.
Co-rich decagonal Al-Co-Ni: predicting structure, orientational order, and puckering

description: We apply systematic methods previously used by Mihalkovic et al. to predict the structure of the `basic' Co-rich modification of the decagonal Al70 Co20 Ni10 layered quasicrystal, based on known lattice constants and previously calculated pair potentials. The modelling is based on Penrose tile decoration and uses Monte Carlo annealing to discover the dominant motifs, which are converted into rules for another level of description. The result is a network of edge-sharing large decagons on a binary tiling of edge 10.5 A. A detailed analysis is given of the instability of a four-layer structure towards $c$-doubling and puckering of the atoms out of the layers, which is applied to explain the (pentagonal) orientational order.
