description: In light of the current (and future) gravitational wave detections, more sensitive tests of general relativity can be devised. Black hole spectroscopy has long been proposed as a way to test the no-hair theorem, that is, how closely an astrophysical black hole can be described by the Kerr geometry. We use simulations from the Simulating eXtreme Spacetimes project to assess the detectability of one extra quasinormal mode in the ringdown of a binary black hole coalescence, with numbers $(\ell,m,n)$ distinct from the fundamental quadrupolar mode (2,2,0). Our approach uses the complex waveform as well as the time derivative of the phase in two prescriptions that allow us to estimate the point at which the ringdown is best described by a single mode or by a sum of two modes. By scaling all amplitudes to $t_{\rm peak}+10M$, our results for non-spinning binaries indicate that for mass ratios of 1:1 to 5:1 the first overtone (2,2,1) will always have a larger excitation amplitude than the fundamental modes of other harmonics, making it a more promising candidate for detection. Even though the (2,2,1) mode damps about three times faster than the higher harmonics and its frequency is very close to that of the (2,2,0) mode, its larger excitation amplitude still guarantees a more favorable scenario for detection. In particular, for equal-mass binaries the ratio of the amplitude of the first overtone (2,2,1) to the fundamental mode (2,2,0) will be $> 0.65$, whereas the corresponding ratio for the higher harmonics will be $< 0.05$. For binaries with mass ratios larger than 5:1 we find that the modes (2,2,1), (2,1,0) and (3,3,0) should have comparable amplitude ratios in the range 0.3 - 0.4. The expectation that the (2,2,1) mode should be more easily detectable than the (3,3,0) mode is confirmed with an extension of the mode resolvability analysis for larger mass ratios.

Q-ball formation: Obstacle to Affleck-Dine baryogenesis in the gauge-mediated SUSY breaking ?

description: We consider the Affleck-Dine baryogenesis comprehensively in the minimal supersymmetric standard model with gauge-mediated supersymmetry breaking. Considering the high temperature effects, we see that the Affleck-Dine field is naturally deformed into the form of the Q ball. In the natural scenario where the initial amplitude of the field and the A-terms are both determined by the nonrenormalizable superpotential, we obtain only very a narrow allowed region in the parameter space in order to explain the baryon number of the universe for the case that the Q-ball formation occurs just after baryon number production. Moreover, most of the parameter sets suited have already been excluded by current experiments. We also find new situations in which the Q-ball formation takes place rather late compared with baryon number creation. This situation is more preferable, since it allows a wider parameter region for naturally consistent scenarios, although it is still difficult to realize in the actual cosmological scenario.

Infinitesimal asphericity changes the universality of the jamming transition

description: The jamming transition of non-spherical particles is fundamentally different from the spherical case. Non-spherical particles are hypostatic at their jamming points, while isostaticity is ensured in the case of the jamming of spherical particles. This structural difference implies that the presence of asphericity affects the critical exponents related to the contact number and the vibrational density of states. Moreover, while the force and gap distributions of isostatic jamming present power-law behaviors, even an infinitesimal asphericity is enough to smooth out these singularities. In a recent work [PNAS 115(46), 11736], we have used a combination of marginal stability arguments and the replica method to explain these observations. We argued that systems with internal degrees of freedom, like the rotations in ellipsoids, or the variation of the radii in the case of the \textit{breathing} particles fall in the same universality class. In this paper, we review comprehensively the results about the jamming with internal degrees of freedom in addition to the translational degrees of freedom. We use a variational argument to derive the critical exponents of the contact number, shear modulus, and the characteristic frequencies of the density of states. Moreover, we present additional numerical data supporting the theoretical results, which were not shown in the previous work.

description: We study gauge mediation models of supersymmetry breaking with neutralino LSP. These models are naturally realized by embedding the usual four-dimensional gauge mediation models into a higher-dimensional spacetime such as $M^4 \times S^1 / Z_{2}$. We calculate the relic abundance of the neutralino LSP in these models and show that there exist wide parameter regions where the neutralino LSP constitutes the dominant component of the cold dark matter. These regions evade constraints from collider experiments such as Higgs mass bounds and $b \ra s γ$, and also provide the value for the muon anomalous magnetic moment which is consistent with the SUSY explanation of the deviation from the standard model prediction.

Dark Energy from Strings

description: A long-standing problem of theoretical physics is the exceptionally small value of the cosmological constant $Λ\sim 10^{-120}$ measured in natural Planckian units. Here we derive this tiny number from a toroidal string cosmology based on closed strings. In this picture the dark energy arises from the correlation between momentum and winding modes that for short distances has an exponential fall-off with increasing values of the momenta. The freeze-out by the expansion of the background universe for these transplanckian modes may be interpreted as a frozen condensate of the closed-string modes in the three non-compactified spatial dimensions.

description: We compute the one-loop density power spectrum including Newtonian and relativistic contributions, as well as the primordial non-Gaussianity contributions from $f_{\rm NL}$ and $g_{\rm NL}$ in the local configuration. To this end we take solutions to the Einstein equations in the long-wavelength approximation and provide expressions for the matter density perturbation at second and third order. These solutions have shown to be complementary to the usual Newtonian cosmological perturbations. We confirm a sub-dominant effect from pure relativistic terms, manifested at scales dominated by cosmic variance, but find that a sizable effect of order one comes from $g_{\rm NL}$ values allowed by Planck-2018 constraints, manifested at scales probed by forthcoming galaxy surveys like DESI and Euclid. As a complement, we present the matter bispectrum at the tree-level including the mentioned contributions.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: Objective: As journal impact factors (IFs) can be artificially inflated by excessive journal self-citation practices, research quality evaluation based solely on IF ranking may be manipulated and, therefore, ethically challenged. This study aimed to analyze the longitudinal development of journal self-citation rates (SCRs) and IFs in dental literature and to determine possible confounders. Methods: Twenty-eight journals with scope within general dentistry and (sub)specialties listed in 1997–2016 Journal of Citation Reports® were scrutinized. The following information was retrieved: publication year, total number of citations, number of self-citations, IF, corrected IF, and SCR. Results: Endodontic journals had the highest SCR (median = 35.3, IQR = 21.6–47.5), journals related to periodontics had the lowest (median = 14.7, IQR = 8.9–25.5). Periodontics had the highest IF (median = 2.1, IQR= 1.7–2.8) and general dentistry had the lowest (median = 0.9, IQR = 0.7–1.2). SCR significantly decreased over time (p p Conclusions: Overall, favourable changes in citation metrics have been observed for dental journals during the 20-year observation period. SCR significantly decreased per observation year whereas IFs significantly increased, indicating a healthy publishing environment in the dental literature. SCR was regulated both by time and corrected IF.

description: We study interacting GaAs hole bilayers in the limit of zero tunneling. When the layers have equal densities, we observe a phase coherent bilayer quantum Hall (QH) state at total filling factor $ν=1$, flanked by insulating phases at nearby fillings which suggest the formation of a pinned, bilayer Wigner crystal. As we transfer charge from one layer to another, the insulating phases disappear while, surprisingly, the $ν=1$ QH state becomes stronger. Concomitantly, a pronounced hysteresis develops in the longitudinal magnetoresistance at higher fillings, indicative of a first-order quantum phase transition.

We find the LL mixing parameter can be as large as |delta_{13}^d_{LL}| < 2*10^-1, but the LR mixing is strongly constrained by the B -> X_d gamma branching ratio and we find |delta_{13}^d_{LR}| < 10^-2. The implications for the direct CP asymmetry in B -> X_d gamma and the dilepton charge asymmetry (A_{ll}) are also discussed, where substantial deviations from the standard model predictions are possible.

description: Agroecotourism is becoming the most dynamical branch of the world tourist industry. The Republic of Belarus has inexhaustible potential for the development of agroecotourism. It promotes a steady development of rural regions, raises well-being of its inhabitants by attracting investments, creates modern social infrastructure and new work places, contributes to the achievement of social and cultural purposes. Agroecotourism is considered to be an important component of a successful realization of the ‘State Program for the Revival and Development of the Countryside in the Republic of Belarus for 2005-2010’. The problem is that the agrotouristic enterprises have not enough money to increase the scale of realization of basic concepts and models stipulated by the National Program. Maintaining and developing the natural and human potential of Belarus will require making the agroecotourism a profitable branch of the agrarian sector of economy.

description: One of the key challenges for future development of efficient and stable metal halide perovskite solar cells is related to the migration of ions in these materials. Mobile ions have been linked to the observation of hysteresis in the current--voltage characteristics, shown to reduce device stability against degradation and act as recombination centers within the band gap of the active layer. In the literature one finds a broad spread of reported ionic defect parameters (e.g. activation energies) for seemingly similar perovskite materials, rendering the identification of the nature of these species difficult. In this work, we performed temperature dependent deep-level transient spectroscopy (DLTS) measurements on methylammonium lead iodide perovskite solar cells and developed a extended regularization algorithm for inverting the Laplace transform. Our results indicate that mobile ions form a distribution of emission rates (i.e. a distribution of diffusion constants) for each observed ionic species, which may be responsible for the differences in the previously reported defect parameters. Importantly, different DLTS modes such as optical and current DLTS yield the same defect distributions. Finally the comparison of our results with conventional boxcar DLTS and impedance spectroscopy (IS) verifies our evaluation algorithm.

Popolo e regimi politici a Firenze nella prima metà del Duecento

description: Tra la fine del XII secolo e l’avvio del successivo, Firenze fu interessata dal passaggio dal regime consolare a quello podestarile. Cominciarono ad affacciarsi alla vita pubblica nuovi soggetti, di origine generalmente modesta ma affermatisi più o meno rapidamente grazie a floride attività mercantili, creditizie, manifatturiere, e all’esercizio di attività liberali, che rivendicavano il diritto di partecipare al governo. Il movimento popolare faceva la sua comparsa nella storia fiorentina. Attraverso le Arti, affiancate poi da organizzazioni a carattere territoriale, esso conquistò sempre più spazi nella vita politica, contrapponendo la propria visione della res publica a quella difesa dalla milizia, gruppo che aveva in mano le redini del potere. Sostenitore di un modello di vita politica e sociale nel quale avesse la preminenza l’autorità pubblica, in cui più equa fosse la ripartizione dei carichi fiscali e più retta la gestione delle finanze e dei beni comunali, il Popolo riuscì ad imporre la propria supremazia politica nel 1250.

description: Alla fine del XVIII secolo, l’Arcispedale di S. Maria Nuova costituiva ormai un modello per l’opinione colta europea. L’ente aveva, infatti, compiuto la trasformazione da ricovero assistenziale per i poveri a luogo della pratica clinica affidata all’integrazione delle competenze professionali di medici, chirurghi e speziali. Il saggio esamina brevemente il percorso delle riforme, con particolare attenzione per i lavori della Deputazione sopra i luoghi pii del 1778-1781 e per gli esiti che ne derivarono: l’accentramento della gestione ospedaliera in mani laiche sotto il diretto controllo del principe, il potenziamento della pratica didattica con l’istituzione di nuove cattedre, la redazione scritta delle norme che reggevano la vita dell’ente con il Regolamento dei Regi spedali di S. Maria Nuova e Bonifazio, dovute a Marco Covoni Girolami e Vincenzo Chiarugi. La ridefinizione delle competenze e delle funzioni riflette tanto l’ampliamento dei compiti dello Stato, quanto il fitto dialogo dei medici coinvolti con il rinnovamento della professione in Francia e in altri stati italiani.

description: Unsupervised machine learning is a cornerstone of artificial intelligence as it provides algorithms capable of learning tasks, such as classification of data, without explicit human assistance. We present an unsupervised deep learning protocol for finding topological indices of quantum systems. The core of the proposed scheme is a 'topological data augmentation' procedure that uses seed objects to generate ensembles of topologically equivalent data. Such data, assigned with dummy labels, can then be used to train a neural network classifier for sorting arbitrary objects into topological equivalence classes. Our protocol is explicitly illustrated on 2-band insulators in 1d and 2d, characterized by a winding number and a Chern number respectively. By using the augmentation technique also in the classification step we can achieve accuracy arbitrarily close to 100% even for objects with indices outside the training regime.

description: La documentazione per la storia della Firenze medievale conosce varie lacune, specialmente per il XIII secolo: in particolare non si conservano che frammenti delle redazioni statutarie prima della fine del secolo. Una tra le fonti normative più antiche disponibili è un breve codice che va sotto il nome di «Provvisioni Canonizzate 1». Si tratta di uno statuto della Camera del Comune, qui per la prima volta edito, redatto nel 1289 e conservatosi in una copia d’inizio ’300. Esso rappresenta la più antica testimonianza dei modi di funzionamento della Camera, ufficio deputato alla gestione delle entrate del Comune oltre che alla conservazione dei suoi atti. Sebbene si conosca l’esistenza della Camera fin dall’inizio del Duecento, la delibera di un così ampio regolamento interno va interpretata come segno della maturità politico-istituzionale raggiunta dal governo del «secondo popolo». A riprova di ciò, la presenza non solo di norme a carattere tecnico, ma anche di un’ampia trattazione sul Consiglio dei Cento, assemblea che deliberava su materie finanziarie e che fino agli anni ’20 del Trecento sarebbe rimasta il primo dei consigli deliberativi del Comune.

description: We discuss models where the U(1) symmetries of lepton numbers are responsible for maximal neutrino mixing. We pay particular attention to an extension of the Standard Model with three right-handed neutrino singlets in which we require that the three lepton numbers L_e, L_μ, and L_τbe separately conserved in the Yukawa couplings, but assume that they are softly broken by the Majorana mass matrix M_R of the neutrino singlets. In this framework, where lepton-number breaking occurs at a scale much higher than the electroweak scale, deviations from family lepton number conservation are calculable, i.e., finite, and lepton mixing stems exclusively from M_R. We show that in this framework either maximal atmospheric neutrino mixing or maximal solar neutrino mixing or both can be imposed by invoking symmetries. In this way those maximal mixings are stable against radiative corrections. The model which achieves maximal (or nearly maximal) solar neutrino mixing assumes that there are two different scales in M_R and that the lepton number \bar L = L_e - L_μ- L_τis conserved in between them. We work out the difference between this model and the conventional scenario where (approximate) \bar L invariance is imposed directly on the mass matrix of the light neutrinos.

description: In the last years Ukraine has allocated considerable, with respect to their load on the budget, financial resources for agricultural support. However the significant increases of budgetary support do not substantially influence the effectiveness indices nor agricultural yields. Such information testifies to an imperfect nature of the internal support mechanism of Ukrainian agriculture. As the result, the domestic support did not become an effective stimulus for a production quality increase nor for a rise in the stock breeding production. In 2008 Ukraine gathered the biggest grain harvest. Increased production did not improve the financial results of agriculture and did not produce a stable and dynamic branch development because of the negative influence of world finance crises. Unbalanced supply and demand for agricultural production, low buying ability of inhabitants, lack of branch effective mechanism of domestic support caused complications of price situation in the domestic food market.

description: We develop a general framework to (numerically) study adiabatic braiding of quasiholes in fractional quantum Hall systems. Specifically, we investigate the Moore-Read (MR) state at $ν=1/2$ filling factor, a known candidate for non-Abelian statistics, which appears to actually occur in nature. The non-Abelian statistics of MR quasiholes is demonstrated explicitly for the first time, confirming the results predicted by conformal field theories.

description: We characterize volatility skews implied by options on futures for hogs and cattle. Both markets have shown a persistent leftward skew. The skew is much more pronounced in live cattle. As a practical matter, the volatility skew is evidence that the cost of using options to insure against large price declines has been considerably more expensive than the cost of using options to insure against similarly large price increases. Out-of-the-money put options are expensive in livestock markets and this is especially the case for out-of-the-money put options on cattle futures. We also examine the relationship between the volatility skew and the ex ante physical returns distribution. We do this by measuring volatility skews just before releases of USDA reports and determine whether they can be empirically linked to the direction of the large price changes that often result. Some responses in live/lean hog futures prices could be explained by characteristics of the pre-report volatility skew. However, there was little evidence linking the volatility skew to post-report responses in live cattle futures.

description: In determining the relationships among prices at the farm, wholesale and retail market levels, it is necessary to determine the lengths of time between infuences and adjustments. For instance, it is commonly assumed, as Bowley pointed out many years ago, that changes in wholesale price will lead to changes in retail price at some point in the future. Within this time period, more than one change in a particular price may have affected the price at another level. The number of past observations of one price variable that describe another is called the lag length. Lag lengths may be determined based on theory, previous studies, biological restrictions or model selection tests.

description: Over the past twenty years, there has been an increasing trend in the number of recalls. Despite increased safety control standards, foodborne disease outbreaks continue to impact the food supply. A common source of foodborne illness and fatal infection is beef from diseases such as E. coli 0157:H7, Listeria Monocytogenes, and Salmonella. Certain companies have even been bankrupted, unable to overcome the social costs and economic losses associated with recalls. We examine beef recalls over a twenty year period through an accumulated two-year index to see if there is a prolonged effect of recalls on current weekly cattle prices. We find that recalls act together, adversely impacting prices and decreasing farm-level revenue. The revenue drop is economically small; therefore, it is uncertain if beef recalls financially incentivize cattle producers to invest in food safety safeguards.

description: Although the production of engineered nanoparticles increases our knowledge of toxicity and mechanisms of bioactivity during relevant exposures is lacking. In the present study mice were exposed to PbO nanoparticles (PbONP; 192.5 µg/m3; 1.93 × 106 particles/cm3) for 2, 5 and 13 weeks through continuous inhalation. The analyses addressed Pb and PbONP distribution in organs (lung, liver, kidney, brain) using electrothermal atomic absorption spectrometry and transmission electron microscopy, as well as histopathology and analyses of oxidative stress biomarkers. New LC-MS/MS methods were validated for biomarkers of lipid damage F2-isoprostanes (8-iso-prostaglandins F2-alpha and E2) and hydroxylated deoxoguanosine (8-OHdG, marker of DNA oxidation). Commonly studied malondialdehyde was also measured as TBARS by HPLC-DAD. The study revealed fast blood transport and distribution of Pb from the lung to the kidney and liver. A different Pb accumulation trend was observed in the brain, suggesting transfer of NP along the nasal nerve to the olfactory bulbs. Long-term inhalation of PbONP caused lipid peroxidation in animal brains (increased levels of TBARS and both isoprostanes). Membrane lipid damage was also detected in the kidney after shorter exposures, but not in the liver or lung. On the contrary, longer exposures to PbONP increased levels of 8-OHdG in the lung and temporarily increased lung weight after 2 and 5 weeks of exposure. The histopathological changes observed mainly in the lung and liver indicated inflammation and general toxicity responses. The present long-term inhalation study indicates risks of PbONP to both human health and the environment.

description: CAR-T cell immunotherapy has achieved remarkable success in malignant B-cell malignancies, but progress in solid tumors is slow, and one of the key reasons is the lack of ideal targets. Cancer-specific extra domain B of fibronectin (EDB-FN) is widely upregulated in solid tumors and expressed at low levels in normal tissues. Many imaging and targeted cancer therapies based on EDB-FN targets have been developed and tested in clinical trials, making EDB-FN an ideal target for immunotherapy. We constructed two EDB-FN-targeted CAR-Ts based on the peptide APT0 and the single-chain antibody CGS2 in a lentiviral infection manner for the first time. Luciferase cytotoxicity assay to assess CAR-T killing of tumor cells. An enzyme-linked immunosorbent assay was used to detect the release of the cytokine IFN-γ. Fluorescence imaging to evaluate the dynamics of CAR-T cell and tumor cell coculture. Knockdown assays were used to validate the target specificity of CAR-T cells. In this research, two CAR-Ts targeting EDB-FN, APT0 CAR-T, and CGS2 CAR-T, were constructed. In vitro, both CAR-T cells produced broad-spectrum killing of multiple EDB-FN-positive solid tumor cell lines and were accompanied by cytokine IFN-γ release. Regarding safety, the two CAR-T cells did not affect T cells’ normal growth and proliferation and were not toxic to HEK-293T human embryonic kidney epithelial cells. APT0 CAR-T and CGS2 CAR-T cells are two new CAR-Ts targeting EDB-FN. Both CAR-T cells can successfully identify and specifically kill various EDB-FN-positive solid tumor cells with potential clinical applications.

description: Extending the principle of local gauge invariance $ψ(x)\to \exp\left(\imath \sum_A ω^A(x)T^A \right) ψ(x), x \in \mathbb{R}^d$, with $T^A$ being the generators of the gauge group $\mathcal{A}$, to the fields $ψ(g)\equiv \langle χ|Ω^*(g)|ψ\rangle$, defined on a locally compact Lie group $G$, $g\in G$, where $Ω(g)$ is suitable square-integrable representation of $G$, it is shown that taking the coordinates ($g$) on the affine group, we get a gauge theory that is finite by construction. The renormalization group in the constructed theory relates to each other the charges measured at different scales. The case of the $\mathcal{A}=SU(N)$ gauge group is considered.

description: Price risk management in the grain industry is typically done by hedging with forward contracts and futures contracts. An additional important price discovery and risk management “paper market” also exists in the form of CIF NOLA basis bids, traded through brokers. These bids function similar to traditional forward contracts, however, like a futures market, firms can offset their forward contractual obligations by offsetting positions in a liquid off-exchange paper market. Analysis shows that this liquidity mostly removes the pricing bias commonly found in forward contracting in corn and soybeans, although a small bias still exists in wheat and especially sorghum.
Firenze: retoriche cittadine e storie della città

description: In questo saggio si affrontano due questioni tra loro connesse: l’analisi delle retoriche cittadine e la costruzione di quel che possiamo definire il racconto della storia di Firenze, così come emerge da opere di larga circolazione. Le retoriche cittadine consentono, da un lato, di misurare — attraverso l’analisi dei discorsi degli esponenti politici, degli articoli dei giornali locali, della produzione degli intellettuali — la consapevolezza che la città, le sue classi dirigenti, i suoi cittadini, hanno dei processi culturali che sono alla base della rappresentazione corrente della loro identità. E, dall’altro, di identificare quali valori, quali simboli, quali forze il ceto dirigente fiorentino intende mobilitare quando ricorre ad un discorso fortemente consolidato nei temi e nelle forme argomentative. Quel che merita dunque di essere studiata è, per così dire, l’idea di città che il ceto politico e i gruppi dirigenti fiorentini intendono affermare con le loro azioni di governo e con i loro discorsi.
