description: The Western Cape of South Africa is a dynamic province that is disaster-prone, in particular
 the vulnerable urban communities in and around its environs. Such communities are more
 vulnerable to wildfire, flooding, drought, pandemic and other natural and human-made
 disasters because of poverty and, consequently, poor living conditions such as overcrowding
 and non-understanding of community resilience. The inability of these communities to
 understand community resilience and withstand adversities affects the sustainability of
 initiatives to develop them. This study aims to identify the mechanisms influencing the level
 of understanding of community resilience in a vulnerable community and to contribute to the
 understanding of community resilience to disaster risk. Fieldwork was conducted in an
 informal settlement in the Western Cape. The research study was conducted in two cycles of
 data collection and analysis (cycle 1 and cycle 2). Data in the form of observation notes,
 document analysis and interviews were analysed using grounded theory principles. Ten
 inter-related variables or mechanisms emerged from the analysis. The theoretical model
 consists of four reinforcing (R) feedback loops (R1, R2, R3 and R4), respectively, which explain
 how the understanding of community resilience in the informal settlement maps on to the
 relative achievement systems archetype. Negative reinforcing behaviour would explain the
 lack of understanding of community resilience, while positive reinforcing behaviour indicates
 how an understanding of community resilience develops. In addition, the variable with the
 leverage to improve the mechanisms influencing the understanding of community resilience
 was found to be the ‘level of public education and public awareness’ of community resilience.
 The theory of how these variables behave in context was represented as a qualitative system
 dynamics model.

LiV$_2$O$_4$: frustration induced heavy fermion metal

description: We propose a two-stage spin quenching scenario for the unusual heavy fermion state realized in the mixed valent metal LiV$_2$O$_4$. In this theory, local valence fluctuations are responsible for the formation of partially quenched, spin 1/2 moments below room temperature. Frustration of the intersite spin couplings then drives the system to produce the heavy Fermi liquid seen at low temperatures. The anomalous resistivity and the sign change of the Hall constant can be understood naturally within this model, which also predicts a unique symmetry for the heavy quasiparticle bands that may be observed in de Haas-van Alphen experiments.

Viability of bi-maximal solution of the Zee mass matrix

description: We know $L_e-L_μ-L_τ$ symmetry gives $m^2_1= m^2_2 >> m^2_3$ pattern in Zee model. $Δm^2_\odot$ emerges from a small breaking of this symmetry. Because this symmetry is broken very weakly $θ_\odot$ does not deviate much from $\tan^2 θ_\odot=1$ which is its value in the symmetric limit. This gives a mismatch with LMA solution where mixing is large but not exactly maximal. We confront this property of Zee mass matrix by phenomenologically analyzing recent results from solar and atmospheric neutrino oscillation experiments at various confidence levels. We conclude that LOW type solution is compatible with the Zee mass matrix at 99% confidence level when atmospheric neutrino deficit is explained by maximal $ν_μ\leftrightarrow ν_τ$ oscillation. Thus the minimal version of the Zee model even though disfavored by the LMA type or VO type solutions, is compatible with LOW type solution of solar neutrino problem.

Note a margine del dibattito tra Blanchard e Brancaccio, con lo sguardo rivolto al contesto italiano

description: Vengono analizzati gli elementi di contatto e di distinzione tra i punti di vista di Blanchard e Brancaccio, cercando di trarre considerazioni più generali sulle differenze tra approcci mainstream e alcuni approcci eterodossi. Si sostiene che negli approcci mainstream viene mantenuta una distinzione concettuale tra domanda e offerta in cui, con maggior nettezza rispetto agli approcci eterodossi, si individuano problemi economici che non possono essere affrontati con la gestione della domanda aggregata, anche qualora se ne ritenga utile o necessaria una gestione attiva. Condividendo questo approccio, si discute brevemente della situazione economica italiana, in cui le debolezze di offerta di lungo periodo si intrecciano con i problemi di domanda, e in cui il livello del debito pone seri vincoli alla possibilità di far ricorso alla spesa per sostenere la domanda interna. Si sottolinea infine l’utilità del dibattito accademico, anche tra scuole di pensiero diverse, che si è aperto dopo la crisi. This article analyses similarities and differences between Blanchard and Brancaccio points of views, trying to elicit some general considerations on the main differences between the mainstream and some heterodox frameworks. Mainstream approaches, more clearly than heterodox approaches, tend to emphasize the existence of economic problems that cannot be addressed by aggregate demand management, even when it is considered useful or necessary. In this vein, the Italian economic situation is briefly discussed, where long-term supply weaknesses are intertwined with demand side problems and where its high public debt restricts the possibility to support domestic demand with public spending. The author also stresses the usefulness of the academic debate that has been opened after the crisis, also across different theoretical approaches. JEL codes: A1, B40, B50, E00

description: In this paper, we propose a deep reinforcement learning (DRL) based mobility load balancing (MLB) algorithm along with a two-layer architecture to solve the large-scale load balancing problem for ultra-dense networks (UDNs). Our contribution is three-fold. First, this work proposes a two-layer architecture to solve the large-scale load balancing problem in a self-organized manner. The proposed architecture can alleviate the global traffic variations by dynamically grouping small cells into self-organized clusters according to their historical loads, and further adapt to local traffic variations through intra-cluster load balancing afterwards. Second, for the intra-cluster load balancing, this paper proposes an off-policy DRL-based MLB algorithm to autonomously learn the optimal MLB policy under an asynchronous parallel learning framework, without any prior knowledge assumed over the underlying UDN environments. Moreover, the algorithm enables joint exploration with multiple behavior policies, such that the traditional MLB methods can be used to guide the learning process thereby improving the learning efficiency and stability. Third, this work proposes an offline-evaluation based safeguard mechanism to ensure that the online system can always operate with the optimal and well-trained MLB policy, which not only stabilizes the online performance but also enables the exploration beyond current policies to make full use of machine learning in a safe way. Empirical results verify that the proposed framework outperforms the existing MLB methods in general UDN environments featured with irregular network topologies, coupled interferences, and random user movements, in terms of the load balancing performance.

Das voll entwickelte, habituell eher einer Raupe ähnelnde Weibchen besitzt stark verkürzte Beine und Fühler. Es ist flügellos und der Ovipositor nur kurz. Das Weibchen bleibt in der Puppenexuvie, die am Vorderende aufreisst. Nur zum Anlocken des Männchens schiebt es sich durch Winden des Körpers bis höchstens zur Hälfte aus der hinteren Öffnung des Sackes heraus 10. Die Sexuallockstoffe (Pheromone) werden von den hypodermalen Drüsen am Nacken produziert (DIERL 1973). Besonders bei Rebelia fallen am Vorderkörper wollige Haarschuppen auf, die vielleicht die Verdunstung der Pheromone fördern. Die Analwolle ist bei dieser Unterfamilie gut ausgebildet. Zur Kopulation schiebt das angelockte Männchen seinen dehnbaren Hinterleib zwischen Weibchen und Puppenhaut an die weibliche Hinterleibsspitze. Die Eier werden in die Puppenhülle abgelegt, danach windet sich das Weibchen aus dem Sack und fällt ab.

description: We investigated the adsorption of a single atom, hydrogen and aluminum, on single wall carbon nanotubes from first-principles. The adsorption is exothermic, and the associated binding energy varies inversely as the radius of the zigzag tube. We found that the adsorption of a single atom and related properties can be modified continuously and reversibly by the external radial deformation. The binding energy on the high curvature site of the deformed tube increases with increasing radial deformation. The effects of curvature and radial deformation depend on the chirality of the tube.

description: L’ovvia lezione della Grande crisi finanziaria è che il sistema finanziario conta e che altre crisi finanziarie probabilmente si verificheranno di nuovo. La seconda lezione, più generale, è che spesso l’economia non è in grado di auto-stabilizzarsi. Queste due lezioni, in un contesto in cui i tassi d’interesse “neutrali” dovrebbero rimanere bassi, hanno chiare implicazioni per la progettazione delle politiche di stabilizzazione. Come minimo, esse suggeriscono che le politiche potrebbero dover diventare più aggressive, sia ex ante che ex post, con un ribilanciamento di ruoli tra politiche monetarie, fiscali e finanziarie. In particolare, bassi tassi “neutrali” riducono i margini d’azione della politica monetaria, ma aumentano la possibilità di utilizzo della politica fiscale. Pensiamo a tale ribilanciamento come una evoluzione. Se tuttavia, i tassi “neutrali” diventeranno ancor più bassi o la regolamentazione finanziaria risulterà insufficiente per prevenire le crisi, potranno rendersi necessarie misure ancor più drastiche, inclusi più ampi disavanzi di bilancio, revisioni degli obiettivi di politica monetaria o restrizioni più severe sul sistema finanziario. Pensiamo a tutto questo come una rivoluzione. Il tempo ci dirà. The obvious lesson from the Great Financial Crisis is that the financial system matters and financial crises will probably happen again. The second, more general, lesson is that the economy is often not self-stabilizing. These two lessons, together with an environment where “neutral” interest rates are likely to remain low, have clear implications for the design of stabilization policies. At a minimum, they suggest that policies may need to become more aggressive, both ex-ante and ex-post, with a rebalancing of the roles of monetary, fiscal and financial policies. In particular, while low “neutral” rates decrease the scope for using monetary policy, they increase the scope for using fiscal policy. Think of such rebalancing as evolution. If however, “neutral” rates become even lower, or financial regulation turns out to be insufficient to prevent crises, more dramatic measures, including larger fiscal deficits, revised monetary policy targets, or sharper restrictions on the financial system, may be needed. Think of this as revolution. Time will tell. JEL codes: E02, E20, E31, E32, E42, E5, E62

Hot Hydrogen Climates near the inner edge of the Habitable Zone

description: Young terrestrial planets can capture or outgas hydrogen-rich atmospheres with tens to hundreds of bars of H2, which persist for 100 Myrs or longer. Although the earliest habitable conditions on Earth and terrestrial exoplanets could thus arise while the atmosphere is still dominated by H2, the climatic effects of H2 remain poorly understood. Previous work showed that H2 induces strong greenhouse warming at the outer edge of the habitable zone. Here we use a 1D radiative-convective model to show that H2 also leads to strong warming near the inner edge of the habitable zone. Unlike H2's greenhouse warming at the outer edge, however, its effect near the inner edge is driven by thermodynamics: H2's large thermal scale height allows the atmosphere to store more water vapor than either a pure-H2O atmosphere or an atmosphere with a heavy background gas, such as N2 or CO2, thereby amplifying the greenhouse effect of H2O. Using idealized grey calculations, we then present a general argument for how different background gases affect the inner edge of the habitable zone. H2 stands out for its ability to induce novel "Souffle" climates, which further support its warming effect. Our results show that if the earliest conditions on a planet near the inner edge of the habitable zone were H2-rich, they were likely also hot: 1 bar of H2 is sufficient to raise surface temperatures above 340 K, and 50 bar of H2 are sufficient to raise surface temperatures above 450 K.

description: In linea con la tradizione del Massachusetts Institute of Technology di cui fanno parte, i modelli macroeconomici mainstream di Olivier Blanchard possono essere sottoposti a un “ribaltamento” logico in grado di renderli compatibili con schemi alternativi che rifiutano la teoria neoclassica dei prezzi come indici di scarsità e il nesso tra produzione e distribuzione che da essa scaturisce. Tale ribaltamento logico sembra in grado di offrire una più solida base teorica alla “rivoluzione” della politica macroeconomica recentemente invocata da Blanchard e Summers, che viene qui sottoposta a un esame critico. In line with the Massachusetts Institute of Technology tradition to which they belong, the macroeconomic models by Olivier Blanchard may be subjected to a logical “reversal” capable of making them consistent with those alternative schemes that reject the neoclassical theory of prices as scarcity indexes and the link between production and distribution resulting from it. This logical reversal seems able to offer a more solid theoretical basis for the macroeconomic policy “revolution” recently invoked by Blanchard and Summers, critically examined here, than the authors’ own schemes.

If the relative toxicity of individual Ti centers in rod-like rutile nanoparticles can be evaluated by the electron density transfer to a Cu2+ probe, its maximal values may be ascribed to the pentacoordinated corner and hexacoordinated edge ones with three Ti-OH bonds. However, these centers exhibit the least negative interaction energies which can be compensated by the significantly better accessibility of the corner Ti center in comparison with the remaining ones. The Ti centers with the most negative interaction energy parameters exhibit the lowest extent of the electron density transfer to a Cu2+ probe. The rutile nanoparticles destruction starts at pentacoordinated Ti face centers

description: The unified model of active galactic nuclei (AGNs) proposes that different AGN optical spectral types are caused by different viewing angles with respect to an obscuring 'torus'. Therefore, this model predicts that type 1 and type 2 AGNs should have similar host-galaxy properties. We investigate this prediction with 2463 X-ray selected AGNs in the COSMOS field. We divide our sample into type 1 and type 2 AGNs based on their spectra, morphologies, and variability. We derive their host-galaxy stellar masses ($M_\star$) through SED fitting, and find that the host $M_\star$ of type 1 AGNs tend to be slightly smaller than those of type 2 AGNs by $Δ\overline{\mathrm{log}M_\star}\approx0.2~\mathrm{dex}$ ($\approx 4σ$ significance). Besides deriving star-formation rates (SFRs) from SED fitting, we also utilize far-infrared (FIR) photometry and a stacking method to obtain FIR-based SFRs. We find that the SFRs of type 1 and type 2 sources are similar once their redshifts and X-ray luminosities are controlled. We also investigate cosmic environment, and find that the surface number densities (sub-Mpc) and cosmic-web environments ($\approx 1\text{--}10$~Mpc) are similar for both populations. In summary, our analyses show that the host galaxies of type 1 and type 2 AGNs have similar SFR and cosmic environment in general, but the former tend to have lower $M_\star$ than the latter. The difference in $M_\star$ indicates that the AGN unification model is not strictly correct and both host galaxy and torus may contribute to the optical obscuration of AGNs.

description: Motivated by the recent synthesis of the spin-1 A-site spinel NiRh2O4, we investigate the classical to quantum crossover of a frustrated J1−J2 Heisenberg model on the diamond lattice upon varying the spin length S. Applying a recently developed pseudospin functional renormalization group approach for arbitrary spin-S magnets, we find that systems with S≥3/2 reside in the classical regime, where the low-temperature physics is dominated by the formation of coplanar spirals and a thermal (order-by-disorder) transition. For smaller local moments S=1 or S=1/2, we find that the system evades a thermal ordering transition and forms a quantum spiral spin liquid where the fluctuations are restricted to characteristic momentum-space surfaces. For the tetragonal phase of NiRh2O4, a modified J1−J−2−J⊥2 exchange model is found to favor a conventionally ordered Néel state (for arbitrary spin S), even in the presence of a strong local single-ion spin anisotropy, and it requires additional sources of frustration to explain the experimentally observed absence of a thermal ordering transition.

It supports spinon and holon excitations, which carry a chirality quantum number. These excitations obey half-fermi statistics. The sign of the statistical parameter is determined by the chirality. The spin 1 chirality liquid is the first example of a two dimensional quantum state which supports excitations with fractional statistics but does not violate P or T.

description: Understanding quantum entanglement in interacting higher-dimensional conformal field theories is a challenging task, as direct analytical calculations are often impossible to perform. With holographic entanglement entropy, calculations of entanglement entropy turn into a problem of finding extremal surfaces in a curved spacetime, which we tackle with a numerical finiteelement approach. In this paper, we compute the entanglement entropy between two half-spaces resulting from a local quench, triggered by a local operator insertion in a CFT3. We find that the growth of entanglement entropy at early time agrees with the prediction from the first law, as long as the conformal dimension Δ of the local operator is small. Within the limited time region that we can probe numerically, we observe deviations from the first law and a transition to sub-linear growth at later time. In particular, the time dependence at large Δ shows qualitative differences to the simple logarithmic time dependence familiar from the CFT2 case. We hope that our work will motivate further studies, both numerical and analytical, on entanglement entropy in higher dimensions.

description: We report the first Atacama large millimeter/submillimeter array observations of MCG-03-58-007, a local ($z=0.03236\pm0.00002$, this work) AGN ($L_{AGN}\sim10^{45}~\rm erg~s^{-1}$), hosting a powerful X-ray ultra-fast ($v=0.1c$) outflow (UFO). The CO(1-0) line emission is observed across $\sim18\,$kpc scales with a resolution of $\sim 1\,\rm kpc$. About 78\% of the CO(1-0) luminosity traces a galaxy-size rotating disk. However, after subtracting the emission due to such rotating disk, we detect with a S/N=20 a residual emission in the central $\sim 4\,$kpc. Such residuals may trace a low velocity ($v_{LOS}=170\,\rm km\,s^{-1}$) outflow. We compare the momentum rate and kinetic power of such putative molecular outflow with that of the X-ray UFO and find $\dot{P}_{out}/\dot{P}_{UFO}=0.3\pm0.2$ and $\dot{E}_{mol}/\dot{E}_{UFO}\sim4\cdot10^{-3}$. This result is at odds with the energy-conserving scenario suggested by the large momentum boosts measured in some other molecular outflows. An alternative interpretation of the residual CO emission would be a compact rotating structure, distinct from the main disk, which would be a factor of $\sim10-100$ more extended and massive than typical circumnuclear disks revealed in Seyferts. However, in both scenarios, our results rule out the hypothesis of a momentum-boosted molecular outflow in this AGN, despite the presence of a powerful X-ray UFO. [Abridged]

description: One of the main challenges in the field of quantum simulation and computation is to identify ways to certify the correct functioning of a device when a classical efficient simulation is not available. Important cases are situations in which one cannot classically calculate local expectation values of state preparations efficiently. In this work, we develop weak-membership formulations of the certification of ground state preparations.Weprovide a non-interactive protocol for certifying ground states of frustration-free Hamiltonians based on simple energy measurements of local Hamiltonian terms. This certification protocol can be applied to classically intractable analog quantum simulations: For example, using Feynman-Kitaev Hamiltonians, one can encode universal quantum computation in such ground states. Moreover, our certification protocol is applicable to ground state encodings of IQP circuits aiming at the demonstration of quantum supremacy. These can be certified efficiently when the error is polynomially bounded.

description: The energy gap between the lowest-lying singlet and triplet states is an important quantity in chemical photocatalysis, with relevant applications ranging from triplet fusion in optical upconversion to the design of organic light-emitting devices. The ab initio prediction of singlet-triplet (ST) gaps is challenging due to the potentially biradical nature of the involved states, combined with the potentially large size of relevant molecules. In this work, we show that phaseless auxiliary-field quantum Monte Carlo (ph-AFQMC) can accurately predict ST gaps for chemical systems with singlet states of highly biradical nature, including a set of 13 small molecules and the ortho-, meta-, and para-isomers of benzyne. With respect to gas-phase experiments, ph-AFQMC using CASSCF trial wavefunctions achieves a mean averaged error of ~1 kcal/mol. Furthermore, we find that in the context of a spin-projection technique, ph-AFQMC using unrestricted single-determinant trial wavefunctions, which can be readily obtained for even very large systems, produces equivalently high accuracy. We proceed to show that this scalable methodology is capable of yielding accurate ST gaps for all linear polyacenes for which experimental measurements exist, i.e. naphthalene, anthracene, tetracene, and pentacene. Our results suggest a protocol for selecting either unrestricted Hartree-Fock or Kohn-Sham orbitals for the single-determinant trial wavefunction, based on the extent of spin-contamination. These findings pave the way for future investigations of specific photochemical processes involving large molecules with substantial biradical character.

description: We examined 40 patients (26 women, 14 men) by a clinical method aged 60 to 70 years with a diagnosis of F4 according to ICD-10 to study the clinical and psychopathological features of anxiety disorders in old age, the dynamics of their development. For this purpose, a clinical method was used using psychometric scales: the Hamilton scale for assessing the severity of anxiety (HARS) and depression (HRDS). As a result of the work, four main syndromes were identified in elderly patients, each of which is based on an obligate symptom anxiety, which prevails at the beginning of the development of the disease. Their clinical and psychopathological structure was determined. It was found that the addition of other psychopathological symptoms to anxiety, such as depression, hypochondria, phobia, contributes to the aggravation and the formation of a more complex syndrome in structure, and increases the duration of the disease.

description: We provide an effective Lagrangian analysis of contact non-standard interactions of neutrinos with electrons, which can be effectively mediated by extra particles, and examine the associated experimental limits. At present, such interactions are strongly constrained only for $ν_μ$: the bounds are loose for $ν_e$ and absent for $ν_τ$. We emphasize the unique role played by the reaction $e^+e^-\to ν\barνγ$ in providing direct constraints on such non-standard interactions.

description: The aim of the work was to study the effect of ozone therapy on the dynamics of the timing of wound healing in children with purulent-inflammatory diseases of the head, face and neck. 580 patients with purulent-inflammatory diseases of the head, face and neck were under observation. The patients, taking into account the applied therapy, were randomized into two groups: the main group 271 patients, in whose complex treatment ozone therapy was included, and the comparison group 309 patients, in whose complex treatment medical ozone was not used.Complex treatment with the inclusion of ozone therapy contributed to the positive dynamics of clinical manifestations, the normalization of indicators of the course of wound healing, a change in the types of cytograms from degenerative-inflammatory to regenerative in terms determined by the biological regularities of the course of the wound process. This led to a decrease in the time for relief of the purulent-inflammatory process by 3.4 ± 0.45 days, in comparison with traditional methods of treatment.

description: One of the most urgent problems in newborns is purulent-inflammatory diseases, which occupy the second place in the structure of the morbidity of newborns, after hypoxia. Pseudofurunculosis is most common in this category of patients, and the latter has a tendency to rapid abscission and the development of sepsis. In the 2-clinic of the Samarkand State Medical Institute for the period from 2016 to 2020, 136 newborns with localization of purulent elements on the head and neck received inpatient treatment. All patients underwent complex surgical treatment. In addition to traditional methods of treatment, the drug Baneocin (zinc bacitracin with neomycin sulfate) and Tyrosur (tyrotricin) were used as local treatment. The use of baneocin and tyrosur in the complex of local treatment had a positive effect on the results of the treatment, which allowed to reduce the time of normalization of body temperature and the time of stay of patients in the hospital.
