description: We present a new framework and associated synthesis algorithms for program synthesis over noisy data, i.e., data that may contain incorrect/corrupted input-output examples. This framework is based on an extension of finite tree automata called {\em weighted finite tree automata}. We show how to apply this framework to formulate and solve a variety of program synthesis problems over noisy data. Results from our implemented system running on problems from the SyGuS 2018 benchmark suite highlight its ability to successfully synthesize programs in the face of noisy data sets, including the ability to synthesize a correct program even when every input-output example in the data set is corrupted.

description: We present optical, near-IR, and radio follow up of sixteen Swift bursts, including our discovery of nine afterglows and a redshift determination for three. These observations, supplemented by data from the literature, provide an afterglow recovery rate of 60% in the optical/near-IR, much higher than in previous missions (BeppoSAX, HETE-2, INTEGRAL, and IPN). The optical/near-IR afterglows of Swift events are on average 1.7 mag fainter at t=12 hr than those of previous missions. The X-ray afterglows are similarly fainter compared to those of pre-Swift bursts. In the radio the limiting factor is the VLA threshold and the detection rate for Swift bursts is similar to that for past missions. The redshift distribution of pre-Swift bursts peaked at z~1, whereas the five Swift bursts with measured redshifts are distributed evenly between 1.3 and 3.2. From these results we conclude that (i) the pre-Swift distributions were biased in favor of bright events and low redshift events, (ii) the higher sensitivity and accurate positions of Swift result in a better representation of the true burst redshift and brightness distributions (which are higher and dimmer, respectively), and (iii) as many as 1/3 of the bursts can be optically dark, as a result of a high redshift and/or dust extinction. We remark that the apparent lack of low redshift, low luminosity Swift bursts, and the lower event rate compared to pre-launch estimates (90 vs. 150 per year), are the result of a threshold that is similar to that of BATSE. In view of these inferences, afterglow observers may find it advisable to make significant changes in follow up strategies of Swift events. [abridged]

description: In this paper we study a relation between two positive geometries: the momentum amplituhedron, relevant for tree-level scattering amplitudes in $\mathcal{N} = 4$ super Yang-Mills theory, and the kinematic associahedron, encoding tree-level amplitudes in bi-adjoint scalar $ϕ^3$ theory. We study the implications of restricting the latter to four spacetime dimensions and give a direct link between its canonical form and the canonical form for the momentum amplituhedron. After removing the little group scaling dependence of the gauge theory, we find that we can compare the resulting reduced form with the pull-back of the associahedron form. In particular, the associahedron form is the sum over all helicity sectors of the reduced momentum amplituhedron forms. This relation highlights the common singularity structure of the respective amplitudes; in particular the factorization channels, corresponding to vanishing planar Mandelstam variables, are the same. Additionally, we also find a relation between these canonical forms directly on the kinematic space of the scalar theory when reduced to four spacetime dimensions by Gram determinant constraints. As a by-product of our work we provide a detailed analysis of the kinematic spaces relevant for the four-dimensional gauge and scalar theories, and provide direct links between them.

description: Electrical transport measurements using a multiterminal configuration are presented, which prove that in BSCCO single crystals near the transition temperature in zero external magnetic field the secondary voltage is induced by thermally activated vortex loop unbinding. The phase transition between the bound and unbound states of the vortex loops was found to be below the temperature where the phase coherence of the superconducting order parameter extends over the whole volume of the sample. We show experimentally that 3D/2D phase transition in vortex dimensionality is a length-scale-dependent layer decoupling process and takes place simultaneously with the 3D/2D phase transition in superconductivity at the same temperature.

Southern Ocean

description: Upwelling of cold water from the deep ocean to the surface of the Southern Ocean is an important climate process because it facilitates the absorption of a large amount of anthropogenic heat and carbon. Upwelling is mediated by turbulent eddies, which allow water from the mid-depths of the ocean to flow to the surface along a southward and upward pathway. Upwelling was previously conceptualised in a longitudinally-averaged framework, but it has recently been observed to vary in strength with longitude. Near topography, such as underwater mountains and ridges, upwelling is enhanced in so-called topographic hotspots of upwelling. The energetics of processes near topographic hotspots of upwelling remain poorly understood. Furthermore, coarse-resolution models used in climate predictions cannot resolve eddies (and thus upwelling) and instead parameterise their behaviour. Understanding the mechanisms that facilitate upwelling hotspots is hence important, as an accurate physical understanding of eddies is required for improved eddy parameterisations and thus climate predictions. Using a high-resolution (0.1 degree) global ocean sea-ice model, I calculate spatial distributions of upwelling transport and energy conversions associated with the upwelling process. I find that five major topographic hotspots of upwelling, covering less than 30% of the circumpolar longitude range, account for up to 76% of the southward eddy upwelling transport. Maximal eddy kinetic energy is found downstream of the upwelling hotspots by on average 130km, in accordance with sparse observational studies. The mechanisms that create the downstream eddy kinetic energy remain unclear, but my energy conversion analysis can identify which mechanisms proposed in the literature are more plausible. I show that upwelling is highly correlated with an energy conversion associated with baroclinic instability, suggesting that eddy parameterisations that quantify baroclinic energy conversions could be used to improve the simulation of upwelling hotspots in climate models.

description: We argue that there exists an infinite class of conformal field theories in diverse dimensions, having a universal ratio of the central charge c to the normalized entropy density c'. The universality class includes all conformal theories which possess a classical gravity dual according to the AdS/CFT correspondence. From the practical point of view, the universality of c/c' provides an explicit test which can be applied to determine whether a given critical point may admit a dual description in terms of classical gravity.

description: The effects of oxygen mole fraction on the static properties of pressure-sensitive paint (PSP) were investigated. Sample coupon tests using a calibration chamber were conducted for polymer-based PSP (PHFIPM-PSP), polymer/ceramic PSP (PC-PSP), and anodized-aluminium PSP (AA-PSP). The oxygen mole fraction was set to be between 0.1-100% and the ambient pressure was set to be between 0.5-140 kPa. The localized Stern-Volmer coefficient $B_{\rm local}$ once increases and then decreases as the oxygen mole fraction increases. The value of $B_{\rm local}$ depends on both ambient pressure and oxygen mole fraction, but the effect of this parameter can be characterized as a function of the partial pressure of oxygen. The value of $B_{\rm local}$ of AA-PSP and PHFIPM-PSP, which are low-pressure type and relatively low-pressure type PSP, have a peak at the relatively low partial pressure of oxygen, and $B_{\rm local}$ of PC-PSP, which are atmospheric pressure type PSP, has a peak at the relatively high partial pressure of oxygen. The peak of the intensity change with respect to pressure fluctuation proportional to the ambient pressure $S_{\mathcal{PR}}$ appears at the lower partial pressure of oxygen than that of $B_{\rm local}$. This is because the intensity of PSP becomes quite low at the high partial pressure of oxygen even if $B_{\rm local}$ is higher. Hence, an optimal partial oxygen mole fraction exists depending on the type of PSP and ambient pressure range of the experiment, and its optimal value can be found based on the partial pressure of oxygen.

AASB Interpretation 23
uncertain tax benefits

tax haven

description: The Australian Accounting Standards Board (AASB) Interpretation 23 requires companies to recognise and disclose liabilities for uncertain income tax positions based on the most likely amount and the expected value methods, and to assume tax authorities have full knowledge of reported information. This study investigates the impact of AASB Interpretation 23 on corporate tax avoidance in Australia. It also examines how this interpretation affects the tax avoidance of firms that engage in aggressive transfer pricing and use tax havens. The final sample consists of 200 publicly listed Australian firms over the 2014–2020 period (i.e. 1,400 firm-years). AASB Interpretation 23 is expected to limit firms’ discretion through the prescribed methods and consequently enhance tax transparency. Therefore, this study hypothesises that corporate tax avoidance has reduced after the adoption of AASB Interpretation 23, and that, in particular, the use of uncertain tax positions (e.g. through high tax haven use and aggressive transfer pricing) has decreased. However, the study’s regression results do not show that (i) AASB Interpretation 23 has reduced the tax avoidance behaviour of Australian companies or that (ii) companies using aggressive transfer pricing and tax havens have decreased their tax avoidance behaviour after adopting this interpretation.

description: Generic higher character Lifshitz critical behaviors are described using field theory and $ε_{L}$-expansion renormalization group methods. These critical behaviors describe systems with arbitrary competing interactions. We derive the scaling relations and the critical exponents at the two-loop level for anisotropic and isotropic points of arbitrary higher character. The framework is illustrated for the $N$-vector $ϕ^{4}$ model describing a $d$-dimensional system. The anisotropic behaviors are derived in terms of many independent renormalization group transformations, each one characterized by independent correlation lengths. The isotropic behaviors can be understood using only one renormalization group transformation. Feynman diagrams are solved for the anisotropic behaviors using a new dimensional regularization associated to a generalized orthogonal approximation. The isotropic diagrams are treated using this approximation as well as with a new exact technique to compute the integrals. The entire procedure leads to the analytical solution of generic loop order integrals with arbitrary external momenta. The property of universality class reduction is also satisfied when the competing interactions are turned off. We show how the results presented here reduce to the usual $m$-fold Lifshitz critical behaviors for both isotropic and anisotropic criticalities.

description: We consider the regression model with errors-in-variables where we observe $n$ i.i.d. copies of $(Y,Z)$ satisfying $Y=f(X)+ξ, Z=X+σε$, involving independent and unobserved random variables $X,ξ,ε$. The density $g$ of $X$ is unknown, whereas the density of $σε$ is completely known. Using the observations $(Y\_i, Z\_i)$, $i=1,...,n$, we propose an estimator of the regression function $f$, built as the ratio of two penalized minimum contrast estimators of $\ell=fg$ and $g$, without any prior knowledge on their smoothness. We prove that its $\mathbb{L}\_2$-risk on a compact set is bounded by the sum of the two $\mathbb{L}\_2(\mathbb{R})$-risks of the estimators of $\ell$ and $g$, and give the rate of convergence of such estimators for various smoothness classes for $\ell$ and $g$, when the errors $ε$ are either ordinary smooth or super smooth. The resulting rate is optimal in a minimax sense in all cases where lower bounds are available.
Science communication through animistic magic in Aboriginal Australian sci-fi texts

description: Fiction is a powerful tool for science communication. Sci-fi, a particularly influential fiction genre, can shape people’s understanding and perceptions of science. Most science communication research pertaining to the meaning-making of science in fiction and in sci-fi has focused on texts written by Western authors – and thus reflect Western meanings of science and visions of the future. To obtain a more comprehensive and culturally inclusive understanding of science communication in fiction, it is important to study how sci-fi written by Indigenous peoples depicts science and conveys its meanings. In my thesis, I investigate how science manifests in four contemporary Aboriginal Australian sci-fi texts. These include the novels The Interrogation of Ashala Wolf (2012), The Disappearance of Ember Crow (2013), and The Foretelling of Georgie Spider (2015) written by Palyku author Ambelin Kwaymullina, as well as the novella Water (2014) by Mununjali author Ellen van Neerven. I uncover and compare how these texts explore the similarities and differences between Western science and Indigenous ways of knowing (that communicate knowledge about the world). In particular, I show how these texts reveal a form of scientific thinking that transcends the typical patterns of Western science, exploring the question of what it means to be human in terms of our reciprocal relationship with and responsibility to nature and its non-human inhabitants. I argue that animistic magic in my four study texts – as a repository of stimulating themes, characters, and literary devices – plays a crucial role in communicating, empowering, and creating meaning out of this Indigenous scientific thinking. In this way, my thesis contributes new perspectives to science communication literature on the cultural meanings of science. Specifically, I add how Aboriginal Australian fiction conveys the importance of complementing Western science with Indigenous ways of knowing to better address 21st century issues related to climate change and sustainability.

description: SPT-CL J2106-5844 is among the most massive galaxy clusters at z>1 yet discovered. While initially used in cosmological tests to assess the compatibility with $Λ$CDM cosmology of such a massive virialized object at this redshift, more recent studies indicate SPT-CL J2106-5844 is undergoing a major merger, and is not an isolated system with a singular, well-defined halo. We use sensitive, high spatial resolution measurements from ALMA and ACA of the thermal SZ effect to reconstruct the pressure distribution of the intracluster medium in this system. These measurements are coupled with radio observations from the EMU pilot survey, using ASKAP and the ATCA to search for diffuse nonthermal emission. Further, to better constrain the thermodynamic structure of the cluster, we complement our analysis with reprocessed archival $Chandra$ observations. We fit the ALMA+ACA SZ data in $uv$-space using a Bayesian forward modelling technique. The ASKAP and ATCA data are processed and imaged to specifically highlight any potential diffuse radio emission. In the ALMA+ACA SZ data, we reliably identify at high significance two main gas components associated with the mass clumps inferred from weak lensing. Our statistical test excludes at the ~9.9$σ$ level the possibility of describing the system with a single SZ component. While the components had been more difficult to identify in the X-ray data alone, we find that the bimodal gas distribution is supported by the X-ray hardness distribution. The EMU radio observations reveal a diffuse radio structure ~400 kpc in projected extent along the northwest-southeast direction, indicative of strong activity from the active galactic nucleus within the brightest cluster galaxy. Interestingly, a putative optical star-forming filamentary structure detected in the HST image is in an excellent alignment with the radio structure, albeit on a smaller scale.

description: Fischzucht im Gleichgewicht
Seit Jahren ist das Thema Überfischung regelmäßig Gegenstand medialer Berichterstattung und wissenschaftlicher Diskurse. Entscheidende Auswirkungen auf die gelebte Praxis lassen dennoch weiter auf sich warten. Die Folgen der massiven Eingriffe in das natürliche Gleichgewicht von Gewässern sind enorm. Grund zur Zuversicht gibt nun das interdisziplinäre HORIZON-IA Projekt "NOVAFOODIES", an dem auch das ACR-Institut LVA beteiligt ist. Mit einer neuen Art der Fischproduktion soll es gelingen, das natürliche Gleichgewicht in aquatischen Ökosystemen wiederherzustellen.
Algen als Produzenten, Doktorfische als primäre Konsumenten und Haie als sekundäre bzw. tertiäre Konsumenten haben eines gemeinsam: Sie sind aufeinander angewiesen. Denn nur wenn alle sogenannten trophischen Stufen der Nahrungspyramide in ausreichender Anzahl vertreten sind, befindet sich das Ökosystem im Gleichgewicht und kann seine Funktionen erfüllen. Kommt es zur Überfischung der Doktorfische, erlaubt das den Algen eine ungehinderte Vermehrung, während die Haie um ihre Nahrungsgrundlage beraubt werden.
Mit "Integrated Multi-Trophic Aquaculture" (IMTA), also der gezielten Anzucht bestimmter Wasserorganismen, soll es gelingen, auf künstliche Art und Weise das natürliche Gleichgewicht in Gewässern einzustellen. Insgesamt sieben Case Studies in Europa, Israel und China werden Zeugnis dafür sein, ob das Konzept in der Praxis halten kann, was es verspricht

Vielversprechend klingen in jedem Fall auch die weiteren Projektziele. Nicht weniger als 28 Konsortiumspartner arbeiten im Rahmen von NOVAFOODIES (Demonstration of innovative functional food production systems based on a more sustainable value chains of marine and freshwater raw materials for conscientious European consumers), koordiniert von der spanischen Forschungseinrichtung IDENER, an der Erforschung und Etablierung innovativer Lebensmittel und Verpackungen aus Algen- und Fischerzeugnissen. Geht es nach den Projektpartnern könnten vermeintliche Abfälle von gestern allzu bald als Fischfutter von morgen dienen. Lebensmittelsicherheit und lückenlose Rückverfolgbarkeit stehen dabei stets im Vordergrund. "So stellen wir sicher, dass nur hochqualitative Produkte erzeugt und auf den Markt gebracht werden, während der Fortbestand aller Wasserorganismen nachhaltig gefördert wird.", fasst Katharina Stollewerk von der LVA die zentralen Projektziele zusammen. Vorrangige Aufgabe der LVA wird es sein, Köch*innen und Lebensmittelproduzent*innen die entwickelten Erzeugnisse im Rahmen von Seminaren, Workshops und (Online-)Kursen näher zu bringen und im wahrsten Sinn des Wortes schmackhaft zu machen.
Dieses Projekt wurde vom Forschungs- und Innovationsprogramm Horizon Europe der Europäischen Union Grant Agreement Nr. 101061023 gefördert.

description: As a result of the worldwide transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), coronavirus disease 2019 (COVID-19) has evolved into an unprecedented pandemic. Currently, with unavailable pharmaceutical treatments and vaccines, this novel coronavirus results in a great impact on public health, human society, and global economy, which is likely to last for many years. One of the lessons learned from the COVID-19 pandemic is that a long-term system with non-pharmaceutical interventions for preventing and controlling new infectious diseases is desirable to be implemented. Internet of things (IoT) platform is preferred to be utilized to achieve this goal, due to its ubiquitous sensing ability and seamless connectivity. IoT technology is changing our lives through smart healthcare, smart home, and smart city, which aims to build a more convenient and intelligent community. This paper presents how the IoT could be incorporated into the epidemic prevention and control system. Specifically, we demonstrate a potential fog-cloud combined IoT platform that can be used in the systematic and intelligent COVID-19 prevention and control, which involves five interventions including COVID-19 Symptom Diagnosis, Quarantine Monitoring, Contact Tracing & Social Distancing, COVID-19 Outbreak Forecasting, and SARS-CoV-2 Mutation Tracking. We investigate and review the state-of-the-art literatures of these five interventions to present the capabilities of IoT in countering against the current COVID-19 pandemic or future infectious disease epidemics.

Regularity and uniqueness results for generated Jacobian equations
Creators: name: Rankin, Cale
Publisher: name: The Australian National University
Year: 2021

description: This is a thesis about generated Jacobian equations; our purpose is twofold. First, we aim to provide an introduction to these equations, whilst, at the same time, collating and unifying some results scattered throughout, and hinted at in, the literature. The other goal is to present the author's own results on these equations. These results all concern solutions of the PDE f*(Y(,u,Du))det DY(x,u,Du) = f(x), for a particular family of vector fields Y:Rn x R x Rn -> Rn. Usually this PDE is paired with the second boundary value problem: Y(.,u,Du)(U) = V. for prescribed domains U,V subsets of Rn. We summarize our results as follows, though warn that the word convexity needs to be understood in an appropriately generalised sense. 1. In two dimensions when f/f* > c > 0 and U is convex, solutions are strictly convex. When f/f* is bounded above and V is convex, solutions are continuously differentiable. 2. When f/f* is pinched between two positive constants, V is convex, and the generating function is defined on a convex domain containing U, solutions are strictly convex and in C1,alpha. The same result holds provided U is uniformly convex and the generating function is defined on a domain containing U. 3. If two C1,1(U) solutions intersect, then they are the same solution. In addition C^1,1 solutions of the Dirichlet problem are unique. 4. Under appropriate uniform convexity hypothesis on U,V and smoothness conditions on f,f* all weak solutions lying in a particular domain are globally smooth. 5. Solutions of the parabolic version of the generated Jacobian equation remain uniformly bounded, independent of time. We want to emphasize that the results of point 2 have already appeared in the works of Guillen and Kitagawa under stronger hypothesis. Our contribution is the weaker hypothesis. Furthermore, on point 4, the existence of globally smooth solutions is due to Jiang and Trudinger. Our contribution is showing weak solutions are globally smooth solutions.

description: We extend Flint, a Spark-based metagenomic profiling tool, to efficiently measure bacterial growth rates for large data sets. The tool bPTR for bacterial growth rate measurement from metagenomic samples [Brown et al., Nat Biotech, 2016] was adapted and integrated into Flint’s MapReduce framework in order to take advantage of Flint's efficient read alignments and mapping, thus enabling the creation of bacterial abundance profiles that are enhanced with growth-rate information.
To show the viability of our method we analyzed whole metagenome sequence data from a longitudinal study of sampled preterm infants [Gibson et al., Nat Micro, 2016], computing the abundance profile enhanced with growth rate information. The conclusions shed light on the new perspective obtained on antibiotics treatments and antibiotic resistance by looking at replication rates.

description: We consider an open quantum system with dissipation, described by a Lindblad Master equation (LME). For dissipation locally acting and sufficiently strong, a separation of the relaxation time scales occurs, which, in terms of the eigenvalues of the Liouvillian, implies a grouping of the latter in distinct vertical stripes in the complex plane at positions determined by the eigenvalues of the dissipator. We derive effective LME equations describing the modes within each stripe separately, and solve them perturbatively, obtaining for the full set of eigenvalues and eigenstates of the Liouvillian explicit expressions correct at order $1/Γ$ included, where $Γ$ is the strength of the dissipation. As a example, we apply our general results to quantum $XYZ$ spin chains coupled, at one boundary, to a dissipative bath of polarization.

description: We present a longitudinal case study of implementing inter-active information radiators in practice. The insights from the case study include the importance of including users in finding relevant information, and of presenting this information in an attractive way. The semi-public space poses special challenges for design and clearly shows the need for doing research through (longitudinal) deployment-based studies. On the other side, the study also shows some problems of doing longitudinal case studies of semi-public installations – particularly field access and availability of quantitative data.

description: The low temperature entropy of the the spin ice compounds, such as Ho$_2$Ti$_2$O$_7$ and Dy$_2$Ti$_2$O$_7$, is well described by the nearest-neighbor antiferromagnetic Ising model on the pyrochlore lattice, i.e.\ by the ``ice rules''. This is surprising since the dominant coupling between the spins is their long ranged dipole interaction. We show that this phenomenon can be understood rather elegantly: one can construct a model dipole interaction, by adding terms of shorter range, which yields {\it precisely} the same ground states, and hence T=0 entropy, as the nearest neighbor interaction. A treatment of the small difference between the model and true dipole interactions reproduces the numerical work by Gingras et al in detail. We are also led to a more general concept of projective equivalence between interactions.

description: In the CommunityMirror project we are researching networked information radiators that are based on large interactive screens showing information from different sources. Most research questions in the project are constructive – e.g. to find design parameters, to find solutions for implementing features and processes. For evaluating our solutions, we always face different problems acquiring the information about usage and non-usage in long term deployments. While working on the issues we found an interesting parallel: Most of the information needed for scientific evaluation is also needed for management issues. In this paper we briefly present the problem scenario – and the current concept for addressing this issue in the CommunityMirror implementation – in the form of a concept for a logging framework.
Primordial black holes and the observed Galactic 511 keV line

description: The observed 511 keV line from the Galactic Bulge is a real challenge for theoretical astrophysics: despite a lot of suggested mechanisms, there is still no convincing explanation and the origin of the annihilated positrons remains unknown. Here we discuss the possibility that a population of slowly evaporating primordial black holes with the mass around $10^{16}-10^{17}$ g ejects (among other particles) low--energy positrons into the Galaxy. In addition to positrons, we have also calculated the spectrum and number density of photons and neutrinos produced by such black holes and found that the photons are potentially observable in the near future, while the neutrino flux is too weak and below the terrestrial and extra--terrestrial backgrounds. Depending on their mass distribution, such black holes could make a small fraction or the whole cosmological dark matter.

description: While charge carrier dynamics and thermal management are both keys to the operational efficiency and stability for energy-related devices, experimental techniques that can simultaneously characterize both properties are still lacking. In this paper, we use laser-induced transient grating (TG) spectroscopy to characterize thin films of the archetypal organic semiconductor regioregular poly(3-hexylthiophene) (P3HT) and its blends with the electron acceptor [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) on glass substrates. While the thermal response is determined to be dominated by the substrates, we show that the recombination dynamics of photocarriers in the organic semiconductor thin films occur on a similar timescale and can be separated from the thermal response. Our measurements indicate that the photocarrier dynamics are determined by multiple recombination processes and our extracted recombination rates are in good agreement with previous reports using other techniques. We further apply TG spectroscopy to characterize another conjugated polymer and a molecular fluorescent material to demonstrate its general applicability. Our study indicates the potential of transient grating spectroscopy to simultaneously characterize thermal transport and photocarrier dynamics in organic optoelectronic devices.

Anomalous internal pair conversion signaling elusive light neutral particles

description: In this paper we report on a systematic search for a neutral boson in the mass range between 5 and 15 MeV/c$^{2}$ in the decay of highly excited nuclei. Its signature is found a deviation in the angular correlation of the $e^+e^-$ pairs from conventional internal pair conversion (IPC) resulting from of its two-body decay kinematics. With an $e^{+}e^{-}$ pair-spectrometer, a number of transitions has been investigated in the $α$--nuclei $^{8}$Be, $^{12}$C and $^{16}$O, following light ion induced reactions at low bombarding energies, first at IKF in Frankfurt and during the last years at ATOMKI in Debrecen. Startlingly, in all isoscalar transitions excess $e^{+}e^{-}$ pairs are found at large angles with branching ratios with respect to the total yield ranging from 10$^{-2}$ to 10$^{-6}$. If these deviations are all related to the two-body decay of an $X$-boson, this observation implies plural $X$-bosons. An analysis of all angular spectra with a boson search program, yields a pandemonium of more than ten candidate bosons.

description: We consider a new approach for gravity theory coupled to Chaplygin matter in which the {\it{relativistic}} formulation of the latter is of crucial importance. We obtain a novel form of matter with dust like density $(\sim (volume)^{-1})$ and negative pressure. We explicitly show that our results are compatible with a relativistic generalization of the energy conservation principle, derived here.

description: Psychological effects can influence the active as well as the passive usage behavior of users of (semi-)public displays, and thus can lead to inaccurate results in evaluations. In this paper, we aim to gather the current knowledge about known and relevant effects in the deployment and operation of (semi-)public screens, so that they can be taken into account when designing or evaluating (semi-)public display applications. Additionally, we collect possible approaches to deal with these effects. The objective of this paper is to support the HCI community in understanding and planning the impact of the enumerated effects in future work.

description: Controlling the COVID-19 pandemic is an urgent global challenge. The rapid geographic spread of SARS-CoV-2 directly reflects the social structure. Before effective vaccines and treatments are widely available, we have to rely on alternative, non-pharmaceutical interventions, including frequency testing, contact tracing, social distancing, mask wearing, and hand-washing, as public health practises to slow down the spread of the disease. However frequent testing is the key in the absence of any alternative. We propose a network approach to determine the optimal low resources setting oriented pool testing strategies that identifies infected individuals in a small number of tests and few rounds of testing, at low prevalence of the virus. We simulate stochastic infection curves on societies under quarantine. Allowing some social interaction is possible to keep the COVID-19 curve flat. However, similar results can be strategically obtained searching and isolating infected persons to preserve a healthier social structure. Here, we analyze which are the best strategies to contain the virus applying an algorithm that combine samples and testing them in groups [1]. A relevant parameter to keep infection curves flat using this algorithm is the dairy frequency of testing at zones where a high infection rate is reported. On the other hand, the algorithm efficiency is low for random search of infected people.
