The Instability of Vacua in Gauss-Bonnet Gravity

description: Owing to the quadratic nature of the theory, Einstein-Gauss-Bonnet gravity generically permits two distinct vacuum solutions. One solution (the "Einstein" vacuum) has a well defined limit as the Gauss-Bonnet coupling goes to zero, whereas the other solution (the "stringy" vacuum) does not. There has been some debate regarding the stability of these vacua, most recently from Deser and Tekin who have argued that the corresponding black hole solutions have positive mass and as such both vacua are stable. Whilst the statement about the mass is correct, we argue that the stringy vacuum is still perturbatively unstable. Simply put, the stringy vacuum suffers from a ghost-like instability that is not excited by the spherically symmetric black hole, but would be excited by any source likely to emit gravitational waves, such as a binary system. This result is reliable except in the strongly coupled regime close to the Chern-Simons limit, when the two vacua are almost degenerate. In this regime, we study instanton transitions between branches via bubble nucleation, and calculate the nucleation probability. This demonstrates that there is large mixing between the vacua, so that neither of them can accurately describe the true quantum vacuum. We also present a new gravitational instanton describing black hole pair production in de Sitter space on the Einstein branch, which is preferred to the usual Nariai instantons, and is not present in pure Einstein gravity.

Sedimentology and chronology of neoglacial Lake Alsek, Yukon Territory
Creators: name: Schmok, Jeffrey Peter
Publisher: name: University of British Columbia
Year: 2010

description: Neoglacial Lake Alsek has formed many times during the last 3000 years when Lowell Glacier has blocked the flow of Alsek River. Although the basin is now empty, evidence for former lakes includes: valley-side beaches, driftwood strandlines, ice-rafted erratics, vegetation discontinuities, and unusually large (outburst-flood related) bedforms. The largest fillings covered approximately 463.0 km² of the valley bottom and were approximately 28.37 km³ in volume. The associated outburst floods produce instantaneous peak discharges estimated at 1.09 x 10⁵ m³ s⁻¹. Alsek valley sediments were examined for a record of past fillings and drainings. Physical, stratigraphic, and lithofacies analyses were conducted on sediment cores. Five facies assemblages are defined and used to interpret depositional environments: (1) matrix supported diamicton interpreted as a deposit of iceberg-rafted sediment, (2) sands interpreted as tractive current deposits, (3) massive muds interpreted as rapidly deposited lake margin derived sediment, (4) laminated muds interpreted as distal glaciolacustrine deposits, and (5) carbonaceous muds interpreted as eutrophic pond organic detritus deposits. Facies sequence analysis indicates non-randomly ordered sedimentary sequences. Cyclic sedimentation is not indicated. Many occurrences of erosional unconformities indicate either depositional hiatuses or an unknown amount of missing sediment. A single radiocarbon date of 2840 ¹⁴C years B.P. underlies 1.04 m of Lake Alsek sediment. This dated material overlies approximately 1.5 m of sediment presumably associated with Lake Alsek. The potential for absolute dating of the Lake Alsek stratigraphy has been shown to be quite high.

description: Multiple transition phenomena in divalent Eu compound EuAl$_4$ with the tetragonal structure were investigated via the single-crystal time-of-flight neutron Laue technique. At 30.0 K below a charge-density-wave (CDW) transition temperature of $T_{\rm CDW}$ = 140 K, superlattice peaks emerge near nuclear Bragg peaks described by an ordering vector $q_{\rm CDW}$=(0 0 $δ_c$) with $δ_c{\sim}$0.19. In contrast, magnetic peaks appear at $q_2 = (δ_2 δ_2 0)$ with $δ_2$ = 0.085 in a magnetic-ordered phase at 13.5 K below $T_{\rm N1}$ = 15.4 K. By further cooling to below $T_{\rm N3}$ = 12.2 K, the magnetic ordering vector changes into $q_1 = (δ_1 0 0)$ with $δ_1$ = 0.17 at 11.5 K and slightly shifts to $δ_1$ = 0.194 at 4.3 K. No distinct change in the magnetic Bragg peak was detected at $T_{\rm N2}$=13.2 K and $T_{\rm N4}$=10.0 K. The structural modulation below $T_{\rm CDW}$ with $q_{\rm CDW}$ is characterized by the absence of the superlattice peak in the (0 0 $l$) axis. As a similar CDW transition was observed in SrAl$_4$, the structural modulation with $q_{\rm CDW}$ could be mainly ascribed to the displacement of Al ions within the tetragonal $ab$-plane. Complex magnetic transitions are in stark contrast to a simple collinear magnetic structure in isovalent EuGa$_4$. This could stem from different electronic structures with the CDW transition between two compounds.

Among the newly discovered 2D ferromagnets all inherit the magnetic ordering from their bulk ancestors. Here we report a new 2D ferromagnetic semiconductor at room temperature, 2H phase vanadium diselenide (VSe2) which show ferromagnetic at 2D form only. This unique 2D ferromagnetic semiconductor manifests an enhanced magnetic ordering owing to structural anisotropy at 2D limit.

description: Industry 4.0 and the associated technological change result in far-reaching modifications not only having an impact on a company’s organization, but also on the people within it. Managers thereby play a crucial role as they form one major component of a successful change process. Hence, the presented Leadership 4.0 training concept was developed in order to further qualify and sensitize managers for new forms of leadership in the era of Industry 4.0. The training module allows production managers to understand how leadership changes through Industry 4.0 and which specific aspects should be taken into consideration, especially with respect to employee management. In contrast to existing leadership trainings, the presented training especially focuses on production environments and is therefore primarily carried out within the wbk Learning Factory on Global Production. This way, changes resulting from digitization and Industry 4.0 can be vividly experienced and transferred to the managers' day-to-day work.

description: ATL is a temporal logic geared towards the specification and verification of properties in multi-agents systems. It allows to reason on the existence of strategies for coalitions of agents in order to enforce a given property. In this paper, we first precisely characterize the complexity of ATL model-checking over Alternating Transition Systems and Concurrent Game Structures when the number of agents is not fixed. We prove that it is Δ^P_2 - and Δ^P_?_3-complete, depending on the underlying multi-agent model (ATS and CGS resp.). We also consider the same problems for some extensions of ATL. We then consider expressiveness issues. We show how ATS and CGS are related and provide translations between these models w.r.t. alternating bisimulation. We also prove that the standard definition of ATL (built on modalities "Next", "Always" and "Until") cannot express the duals of its modalities: it is necessary to explicitely add the modality "Release".

Cancer: secret in genetic code and DNA mismatch repair genes. Abnomalities of these genes can be both from mutations and epigenetics. However, cancer is not a single gene disorder. Tumorigenesis is a lengthy process and several gene mutations need to accumulate for a long time for cancer to develop. Nowadays, pharmacogenetics has been used in cancer therapy. For example, drug therapy for EGFR mutation has been used for lung cancer patients. Therefore, knowledge from genetic study can be applied in clinical development for improving quality of human life.

description: This paper presents the results of the Rubin Observatory Dark Energy Science Collaboration (DESC) 3x2pt tomography challenge, which served as a first step toward optimizing the tomographic binning strategy for the main DESC analysis. The task of choosing an optimal tomographic binning scheme for a photometric survey is made particularly delicate in the context of a metacalibrated lensing catalogue, as only the photometry from the bands included in the metacalibration process (usually riz and potentially g) can be used in sample definition. The goal of the challenge was to collect and compare bin assignment strategies under various metrics of a standard 3x2pt cosmology analysis in a highly idealized setting to establish a baseline for realistically complex follow-up studies; in this preliminary study, we used two sets of cosmological simulations of galaxy redshifts and photometry under a simple noise model neglecting photometric outliers and variation in observing conditions, and contributed algorithms were provided with a representative and complete training set. We review and evaluate the entries to the challenge, finding that even from this limited photometry information, multiple algorithms can separate tomographic bins reasonably well, reaching figures-of-merit scores close to the attainable maximum. We further find that adding the g band to riz photometry improves metric performance by ~15% and that the optimal bin assignment strategy depends strongly on the science case: which figure-of-merit is to be optimized, and which observables (clustering, lensing, or both) are included.

description: Shaping axi-symmetric planetary nebulae is easier if a companion interacts with a primary at the top of the asymptotic giant branch. To determine the impact of binarity on planetary nebula formation and shaping, we need to determine the central star of planetary nebula binary fraction and period distribution. The short-period binary fraction has been known to be 10-15% from a survey of ~100 central stars for photometric variability indicative of irradiation effects, ellipsoidal variability or eclipses. This survey technique is known to be biased against binaries with long periods and this fact is used to explain why the periods of all the binaries discovered by this survey are smaller than 3 days. In this paper we assess the status of knowledge of binary central stars discovered because of irradiation effects. We determine that, for average parameters, this technique should be biased against periods longer than 1-2 weeks, so it is surprising that no binaries were found with periods longer than 3 days. Even more puzzling is the fact that 9 out of 12 of the irradiated binaries, have periods smaller than one day, a fact that is starkly at odds with post-common envelope predictions. We suggest that either all common envelope models tend to overestimate post-common envelope periods or that this binary survey might have suffered from additional, unquantified biases. If the latter hypothesis is true, the currently-known short-period binary fraction is put in serious doubt. We also introduce a new survey for binary-related variability, which will enable us to better quantify biases and determine an independent value for the short period binary fraction.

description: In public relations and political communication, a spin is a form of propaganda achieved through knowingly presenting a biased interpretation of an event or issues. It is also the act of presenting narratives to influence public opinion about events, people or and ideas. In war time, various forms of spins are employed by antagonists to push their brigades to victory and wear out the opponents. During the Nigerian civil war, quite a number of these spins were dominant for example GOWON (Go On With One Nigeria); On Aburi We Stand, O Le Ku Ija Ore. Post-war years presented different spins and fifty years after the war, different spins continue to push emerging narratives (e.g. marginalization, restructuring. This paper investigates and analyzes the different propaganda techniques and spins in the narratives of the Nigerian civil in the past five years through a content analysis of three national newspapers: The Nigerian Tribune, Daily Trust and Sun Newspapers. Findings confirm that propaganda and spins are not limited to war time, but are actively deployed in peace time. This development places additional challenge on journalists to uphold the canons of balance, truth and fairness in reporting sensitive national issues.

description: Chiral dynamics is investigated using the chiral confining Lagrangian (CCL), previously derived from QCD with confinement interaction. Based on the calculations of the quark condensate, which is defined entirely by confinement in the zero quark mass limit, one can assert that chiral symmetry breaking occurs not spontaneously but is predetermined by confinement. The expansion of the CCL provides the GMOR relations and the effective chiral Lagrangian, which is used to provide the masses and decay constants of all chiral mesons, including $η,η'$. For the latter one needs to define a non-chiral component due to confinement, while the orthogonality condition defines the wave functions and the eigenvalues. The resulting masses and decay constants of all chiral mesons are obtained in good agreement with experimental and lattice data.

description: We present the properties of 11 $μ$m selected sources detected in the early data of the North Ecliptic Pole Deep (NEP-Deep) Survey of AKARI. The data set covers 6 wavelength bands from 2.5 to 11 $μ$m, with the exposure time of 10 ~ 20 minutes. This field lies within the CFHT survey with four filter bands ($g', r', i',z'), enabling us to establish nearly continuous spectral energy distributions (SEDs) for wavelengths ranging from 0.4 to 11 $μ$m. The main sample studied here consists of 71 sources whose 11 $μ$m AB magnitudes are equal to or brighter than 18.5 (251 $μ$Jy), which is complete to more than 90%. The 11 $μ$m band has an advantage of sampling star forming galaxies with low to medium redshifts since the prominent PAH feature shifts into this band. As expected, we find that the majority (~68%) of 11 $μ$m bright sources are star forming galaxies at 0.2 < z < 0.7 with $L_{IR} ~ 10^{10}$ -- $10^{12} L_{\odot}$ based on the detailed modelling of SEDs. We also find four AGNs lying at various redshifts in the main sample. In addition, we discuss a few sources which have non-typical SEDs of the main sample, including a brown dwarf candidate, a steep power-law source, flat spectrum object, and an early-type galaxy at moderate redshift.

On some regularity results of Jacobian determinants and applications
Creators: name: Radice, Teresa
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2006

description: The starting point in the theory of the regularity of the
Jacobian is the celebrated result due to S. Müller [M] that for an orientation preserving mapping f ε  W1,n loc  (Ω, Rn), J belongs to the Zygmund space L log L(K) for any compact K C Ω.
The improved integrability property of the Jacobian could be observed in Orlicz-Sobolev spaces near W-1,n loc (Ω, Rn)(see [IS], [BFS], [MO], [GIOV], [GIM])).
As suggested in [BFS] it is interesting to study the regularity of the Jacobian when Df belongs to Lorentz spaces. It appears that to get positive results one cannot rely only on these spaces but it is forced to encode the theory in the Lorentz-Zygmund spaces.
It is also possible to extend this study to the couple (B,E), B : Ω → Rn, E → Rn, of vector fields on Ω, such that divB = 0 and curl E = 0, having the scalar product ‹ B,E › nonnegative. In this case we obtain results of higher integrability for the scalar product ‹ B,E ›. R. Coifman, P.L. Lions, Y. Meyer and S. Semmes in a famous paper "Compensated compactness and Hardy spaces" studied the regularity of the mappings with Jacobian of arbitrary sign and as a consequence of couple (B,E), belonging to Lebesgue
spaces, where divB = 0 and curl E = 0 whose scalar product is of arbitrary sign. Following this idea, we study analogous regularity properties of couple in the framework of Lorentz spaces.
The last chapter is devoted to study nondivergence elliptic equations, applying the results found previously. We develop a theory for elliptic equations with bounded coecients having sufficiently small BMO-norm and we find a higher integrability of the solution. More delicate is the case of unbounded coecients, our main result is a L2 log L estimate for |V2u|.

description: The learning of a new language remains to this date a cognitive task that requires considerable diligence and willpower, recent advances and tools notwithstanding. In this paper, we propose Broccoli, a new paradigm aimed at reducing the required effort by seamlessly embedding vocabulary learning into users' everyday information diets. This is achieved by inconspicuously switching chosen words encountered by the user for their translation in the target language. Thus, by seeing words in context, the user can assimilate new vocabulary without much conscious effort. We validate our approach in a careful user study, finding that the efficacy of the lightweight Broccoli approach is competitive with traditional, memorization-based vocabulary learning. The low cognitive overhead is manifested in a pronounced decrease in learners' usage of mnemonic learning strategies, as compared to traditional learning. Finally, we establish that language patterns in typical information diets are compatible with spaced-repetition strategies, thus enabling an efficient use of the Broccoli paradigm. Overall, our work establishes the feasibility of a novel and powerful "install-and-forget" approach for embedded language acquisition.

description: Soil fungi play an important role in the process of planting tea tree. However, effects of acidification on the diversity and function of the fungi community in tea rhizosphere soil have been rarely reported. In this study, tea rhizosphere soils with pH of 3.3, 4.7, 5.3 and 6.4 were investigated for diversity and function of fungal communities through T-RFLP technology. The results showed that the abundance and diversity of fungi increased significantly with the decrease of pH value of rhizosphere soil. The results of significance analysis showed that 38 T-RFs fragments were significantly correlated with pH value, among which 32 were negatively correlated with pH value and 6 were positively correlated with pH value. After database comparison, 23 fungi were identified and classified according to their nutritional patterns, which can be divided into four types, including pathotroph, symbiotroph, saprotroph and unknown, accounting for 36.85%, 7.89%, 15.79% and 39.47%, respectively. At pH value of 3.3, the fungus abundance reached the maximum value. In conclusion, acidification leads to changes in the structure and diversity of the fungi community in tea rhizosphere soil, specifically, a significant increase in the number and species of fungi, of which the pathotroph type is the largest. This study provides an important theoretical basis for controlling fungal diseases of tea tree in acidified tea plantations

description: ITA
L’innovazione nel campo dei materiali ha portato in anni recenti alla diffusione di nuove classi di prodotti con caratteristiche inedite, spesso realizzati con materiali “progettati” in relazione alle prestazioni ricercate, caratterizzati da un elevato contenuto di informazione, capaci di esprimere elevati livelli prestazionali derivanti da particolari conformazioni chimico-fisiche.
Nel settore edilizio, enormi potenzialità sembrano poter derivare dalla diffusione di materiali nanostrutturati, in grado di combinare, attraverso l’impiego di nanotecnologie, le caratteristiche dei nanomateriali a quelle di materiali tradizionali quali acciaio, cemento, vetro o polimeri.
La ricerca si concentra sulle diverse tipologie di materiali cementizi nanostrutturati, da quelli presenti sul mercato a quelli attualmente ancora in fase di sperimentazione. Tali materiali possono contribuire all'eco-efficienza delle soluzioni tecniche attraverso il risparmio di risorse materiali ed energetiche durante l'intero ciclo di vita, grazie all’impiego di minori quantità di materie prime, alla riduzione delle operazioni di manutenzione necessarie, fino alla capacità di assorbire sostanze inquinanti, garantendo durabilità e affidabilità.
Considerando l’evoluzione dei processi innovativi legati alle nanotecnologie, il numero crescente di applicazioni in edilizia e i fattori di rischio per l’ambiente correlati, la ricerca punta alla definizione di una metodologia di studio che consenta di valutare e validare il progressivo passaggio dall’ambito sperimentale ad una effettiva diffusione analizzando le prestazioni espresse da tali materiali in condizioni d’uso, con un’attenzione particolare all’eco-efficienza dei processi produttivi e del ciclo di vita dei prodotti.

description: BackgroundReactive arthritis, irritable bowel syndrome (IBS), Guillain-Barré syndrome, ulcerative colitis, and Crohn's disease may be sequelae of Campylobacter or non-typhoidal Salmonella (NTS) infections. Proton pump inhibitors (PPI) and antibiotics may increase the risk of gastrointestinal infections (GII); however, their impact on sequelae onset is unclear. We investigated the incidence of sequelae, their association with antibiotics and PPI prescription, and assessed the economic impact on the NHS.MethodsData from the Clinical Practice Research Datalink for patients consulting their GP for Campylobacter or NTS infection, during 2000–2015, were linked to hospital, mortality, and Index of Multiple Deprivation data. We estimated the incidence of sequelae and deaths in the 12 months following GII. We conducted logistic regression modelling for the adjusted association with prescriptions. We compared differences in resource use and costs pre- and post-infection amongst patients with and without sequelae.FindingsOf 20,471 patients with GII (Campylobacter 17,838), less than 2% (347) developed sequelae, with IBS (268) most common. Amongst Campylobacter patients, those with prescriptions for PPI within 12 months before and cephalosporins within 7-days before/after infection had elevated risk of IBS (adjusted odds ratio [aOR] 2.1, 1.5–2.9) and (aOR 3.6, 1.1–11.7) respectively. Campylobacter sequelae led to ∼ £1.3 million, (£750,000, £1.7 million) in additional annual NHS expenditure.InterpretationSequelae of Campylobacter and NTS infections are rare but associated with increased NHS costs. Prior prescription of PPI may be a modifiable risk factor. Incidence of sequelae, healthcare resource use and costs are essential parameters for future burden of disease studies.

description: Rigorous analysis of diversity-dependence—the hypothesis that the rate of proliferation of new species is inversely related to standing diversity—requires consideration of the ecology of the organisms in question. Differences between infaunal marine bivalves (living entirely within the sediment) and epifaunal forms (living partially or completely above the sediment-water interface) predict that these major ecological groups should have different diversity dynamics: epifaunal species may compete more intensely for space and be more susceptible to predation and physical disturbance. By comparing detrended standing diversity with rates of diversification, origination, and extinction in this exceptional fossil record, we find that epifaunal bivalves experienced significant, negative diversity-dependence in origination and net diversification, whereas infaunal forms show little appreciable relationship between diversity and evolutionary rates. This macroevolutionary contrast is robust to the time span over which dynamics are analysed, whether mass-extinction rebounds are included in the analysis, the treatment of stratigraphic ranges that are not maximally resolved, and the details of detrending. We also find that diversity-dependence persists over hundreds of millions of years, even though diversity itself rises nearly exponentially, belying the notion that diversity-dependence must imply equilibrial diversity dynamics.

description: The resonant state of the open quantum system is studied from the viewpoint of the outgoing momentum flux. We show that the number of particles is conserved for a resonant state, if we use an expanding volume of integration in order to take account of the outgoing momentum flux; the number of particles would decay exponentially in a fixed volume of integration. Moreover, we introduce new numerical methods of treating the resonant state with the use of the effective potential. We first give a numerical method of finding a resonance pole in the complex energy plane. The method seeks an energy eigenvalue iteratively. We found that our method leads to a super-convergence, the convergence exponential with respect to the iteration step. The present method is completely independent of commonly used complex scaling. We also give a numerical trick for computing the time evolution of the resonant state in a limited spatial area. Since the wave function of the resonant state is diverging away from the scattering potential, it has been previously difficult to follow its time evolution numerically in a finite area.

description: Among the most damaging characteristics of the covid-19 pandemic has been its disproportionate effect on disadvantaged communities. As the outbreak has spread globally, factors such as systemic racism, marginalisation, and structural inequality have created path dependencies that have led to poor health outcomes. These social determinants of infectious disease and vulnerability to disaster have converged to affect already disadvantaged communities with higher levels of economic instability, disease exposure, infection severity, and death. Artificial intelligence (AI) technologies are an important part of the health informatics toolkit used to fight contagious disease. AI is well known, however, to be susceptible to algorithmic biases that can entrench and augment existing inequality. Uncritically deploying AI in the fight against covid-19 thus risks amplifying the pandemic's adverse effects on vulnerable groups, exacerbating health inequity. In this paper, we claim that AI systems can introduce or reflect bias and discrimination in three ways: in patterns of health discrimination that become entrenched in datasets, in data representativeness, and in human choices made during the design, development, and deployment of these systems. We highlight how the use of AI technologies threaten to exacerbate the disparate effect of covid-19 on marginalised, under-represented, and vulnerable groups, particularly black, Asian, and other minoritised ethnic people, older populations, and those of lower socioeconomic status. We conclude that, to mitigate the compounding effects of AI on inequalities associated with covid-19, decision makers, technology developers, and health officials must account for the potential biases and inequities at all stages of the AI process.

description: The black-hole X-ray transient MAXI J1820+07 (=ASSASN-18ey) discovered in March 2018 was one of the optically brightest ever seen, which has resulted in very detailed optical outburst light-curves being obtained. We combine them here with X-ray and radio light-curves to show the major geometric changes the source undergoes. We present a detailed temporal analysis that reveals the presence of remarkably high amplitude (>0.5 mag) modulations, which evolve from the superhump (16.87 h) period towards the presumed orbital (16.45 h) period. These modulations appear ~87d after the outburst began, and follow the Swift/BAT hard X-ray light-curve, which peaks 4 days before the radio flare and jet ejection, when the source undergoes a rapid hard to soft state transition. The optical modulation then moves closer to the orbital period, with a light curve peak that drifts slowly in orbital phase from ~0.8 to ~0.3 during the soft state. We propose that the unprecedentedly large amplitude modulation requires a warp in the disc in order to provide a large enough radiating area, and for the warp to be irradiation-driven. Its sudden turn-on implies a change in the inner disc geometry that raises the hard X-ray emitting component to a height where it can illuminate the warped outer disc regions.
