description: Σκοπός της παρούσας εργασίας είναι να μελετήσουμε την έννοια της παρθενίας, κατά τον Αμβρόσιο Μεδιολάνων αλλά και όπως αυτή είχε διαμορφωθεί τον 4ο αιώνα. Επίσης προσπαθούμε να κατανοήσουμε τη θεολογία σχετικά με την παρθενία και τη σημασία που έδιναν οι πατέρες στην έννοια αλλά και στην εφαρμογή της την εποχή εκείνη. Όπως πολλοί πατέρες της Εκκλησίας τόσο της Ανατολής όσο και της Δύσης, έτσι και ο Αμβρόσιος σε πολλά έργα του μιλάει για τον θεσμό του γάμου αλλά και για την παρθενία. Στην εργασία μελετώντας τις απόψεις του Αμβρόσιου για την παρθενία, μέσα από τα έργα του, βλέπουμε να δείχνει ιδιαίτερη αφοσίωση προς τον ασκητισμό και να επαινεί την παρθενία. Η αγαμία και ο παρθενικός βίος σύμφωνα με τον Αμβρόσιο θεωρήθηκαν ο μόνος τρόπος για να καταφέρει κάποιος να αφοσιωθεί απόλυτα στην αγάπη του Χριστού.
description: The aim of this project is the studying of the concept of Virginity according to Ambrosius Mediolanum and as this concept had been formed during the 4th century as well.We also try to understand Theology in relation with virginity and the importance given by Fathers of Church to the significance of Virginity and its implementation as well. As many Fathers of Eastern and Western Church, Ambrosius deals with the institution of Marriage and Virginity in many of his works. In this project, studying Ambrosius views about Virginity, we can see through his works that he shows a peculiar dedication to asceticism and he praises Virginity. Celibacy pure life were considered by Ambrosius the only way for someone to manage to be dedicated fully to Christ’s Love.

Laicità e vita consacrata

description: Sulla base della visione di laicità quale condizione comune, l’ipotesi che suggeriamo è
che la proposta educativa della vita consacrata possa contribuire al servizio di un
percorso di umanizzazione e di costruzione di uno spazio pubblico ospitale, dialogico,
solidale. Ne consegue che il contributo della vita consacrata nei processi di evangelizzazione
si esplicita nella capacità di essere profezia di significato per il mondo globale e
complesso come il nostro. Da questa angolatura, il prezioso e importante compito delle
comunità di vita consacrata sta nell’educare e formare a un’identità cristiana. Compito
possibile, se conserva la sua significatività antropologica e la capacità di proporre
stili di vita credibili. In ragione di tale prospettiva orientativa, la vita consacrata può
(e deve) articolare tre dimensioni importanti che caratterizzano l’esistenza cristiana:
l’orizzonte religioso, il contesto sociale e la prospettiva culturale.

Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: We demonstrate the utility of Raman spectroscopy as a technique for the identification of ancient glasses and enamel coatings of ceramics. As for any silicate glasses, the addition of network modifiers breaks the Si-O linkages and modifies the degree of polymerisation and hence the relative intensity of the Si-O bending and stretching modes. We demonstrate empirically that the ratio of these envelopes is well correlated to the glass structure and to the used firing technology. Spectral Qn components assigned to isolated and connected SiO4 vibrational units allow more precise analysis. Selected porcelains, faiences, potteries and glasses representative of the different Asian, Islamic and European production technologies were studied. Modern porcelain enamels are used as compositional references.

description: Models with fermions in bifundamental representations can lead naturally to family unification as opposed to family replication. Such models typically predict (exotic) color singlet states with fractional electric charge, and magnetic monopoles with multiple Dirac charge. The exotics may be at the TeV scale, and relatively light magnetic monopoles (greater than about 10^7 GeV) can be present in the galaxy with abundance near the Parker bound. We focus on three family SU(4)XSU(3)XSU(3) models.

description: The origin of the intermediate anomalous metallic state in two-dimensional superconductor materials remains enigmatic. In the present paper, we observe such a state in a series of $\sim$9.0 nm thick Ta$_x$(SiO$_2$)$_{1-x}$ ($x$ being the volume fraction of Ta) nanogranular films. At zero field, the $x$ $\gtrsim$ 0.75 films undergo a Berezinskii-Kosterlitz-Thouless transition as transform from normal to superconducing states upon cooling. For the $x$ $\lesssim$ 0.71 films, the resistance increases with decreasing temperature from 2 K down to 40 mK. A normal state to anomalous metallic state transition is observed in the $x$ $\simeq$ 0.73 film, i.e., near the transition temperature, the resistance of the film decreases sharply upon cooling as if the system would cross over to superconducting state, but then saturates to a value far less than that in normal state. When a small magnetic field perpendicular to the film plane is applied, the anomalous metallic state occurs in the $x$ $\gtrsim$ 0.75 films. It is found that both disorder and magnetic field can induce the transition from superconductor to anomalous metal and their influences on the transition are similar. For the the magnetic field induced case, we find the sheet resistance $R_{\square}(T,H)$ ($T$ and $H$ being the temperature and the magnitude of magnetic field) data near the crossover from the anomalous metal to superconductor and in the vicinity of the anomalous metal to insulator transition, respectively, obey unique scaling laws deduced from the Bose-metal model. Our results strongly suggest that the anomalous metallic state in the Ta$_x$(SiO$_2$)$_{1-x}$ granular films is bosonic and dynamical gauge field fluctuation resulting from superconducting quantum fluctuations plays a key role in its formation.

description: The invasive measurement of the hepatic venous pressure gradient is still considered as the reference method to assess the severity of portal hypertension. Even though previous studies have shown that the liver stiffness measured by elastography could predict portal hypertension in patients with chronic liver disease, the mechanisms behind remain today poorly understood. The main reason is that the liver stiffness is not specific to portal hypertension and is also influenced by concomitant pathologies, such as cirrhosis. Portal hypertension is also source of a vascular incidence, with a substantial diversion of portal venous blood to the systemic circulation, bypassing the liver. This study focuses on this vascular effect of portal hypertension. We propose to generate and control the portal venous flow (to isolate the modifications in the portal venous flow as single effect of portal hypertension) in an anesthetized pig and then to quantify its implications on liver stiffness by an original combination of MRE and 4D-Flow Magnetic Resonance Imaging (MRI). A catheter balloon is progressively inflated in the portal vein and the peak flow, peak velocity magnitude and liver stiffness are quantified in a 1.5T MRI scanner (AREA, Siemens Healthcare, Erlangen, Germany). A strong correlation is observed between the portal peak velocity magnitude, the portal peak flow or the liver stiffness and the portal vein intraluminal obstruction. Moreover, the comparison of mechanical and flow parameters highlights a correlation with the possibility of identifying linear relationships. These results give preliminary indications about how liver stiffness can be affected by portal venous flow and, by extension, by hypertension.

description: A number of independent observations suggest that the intergalactic medium was significantly neutral at $z=7$ and that reionization was, perhaps, still in progress at $z=5.7$. The narrowband survey, SILVERRUSH, has mapped over $2,000$ Lyman-$α$ emitters (LAEs) at these redshifts. Previous analyses have assumed that reionization was over by $z=5.7$, but this data may actually sample the final stages of reionization when the last neutral islands were relegated to the cosmic voids. Motivated by these developments, we reexamine LAE void and peak statistics and their ability to constrain reionization. We construct models of the LAE distribution in (1 Gpc$/h$)$^3$ volumes, spanning a range of neutral fractions at $z=5.7$ and 6.6. Models with a higher neutral fraction show an enhanced probability of finding holes in the LAE distribution. When comparing models at fixed mean surface density, however, LAEs obscured by neutral gas in the voids must be compensated by visible LAEs elsewhere. Hence, in these models the likelihood of finding an over-dense peak is also enhanced in the latter half of reionization. Compared to the widely used angular two-point correlation function (2PCF), we find that the void probability function (VPF) provides a more sensitive test of models during the latter half of reionization. By comparison, at neutral fractions $\sim 50\%$, the VPF and a simple peak thresholding statistic are both similar to the 2PCF in constraining power. Lastly, we find that the cosmic variance and large-scale asymmetries observed in the SILVERRUSH fields are consistent with large-scale structure in a $Λ$CDM universe.

description: In un mondo in continuo mutamento e sempre più segnato dalla crisi vocazionale, dal
materialismo e dall’individualismo, l’attualità della vita consacrata diviene essa stessa
sfida quando, ispirata dal vangelo, si pone a servizio della ricerca della verità per tutti
e infonde forza e senso rinnovati ai voti di castità, povertà e obbedienza, ovvero amore
incondizionato e disinteressato verso l’altro da sé, aspirazione a una vita povera di
pretese e ricca di desideri, ascolto della verità della Parola e adesione a Cristo, verità in
persona e fondamento della libertà. La vita consacrata è sfida anche quando si presenta
come superamento delle spinte individualiste e promuove all’interno delle comunità
una rinnovata fraternità fondata sul dialogo interattivo, quando ri-crea la forma della
fedeltà dietro la spinta di un nuovo umanesimo, quando si apre all’accoglienza intesa
come servizio ai poveri e agli ultimi e occasione di evangelizzazione.

Publisher: name: Zenodo
Year: 2017

description: This research paper examines the critical role of agricultural credit in enhancing farmer productivity inRajasthan, India. The study highlights the disparities in credit access among farmers and the impact this has onagricultural output. Through a mixed-methods approach, involving quantitative surveys of 400 farmers andqualitative analyses of existing literature, the research identifies the challenges faced in accessing formal credit,including bureaucratic hurdles, lack of financial literacy, and socio-economic constraints. The findings revealthat farmers with access to institutional credit experience productivity increases of up to 30% compared to thoserelying on informal sources. Additionally, the paper discusses the effectiveness of government initiatives, suchas the Kisan Credit Card scheme, which has improved access for millions of farmers but still leaves asignificant portion dependent on informal loans. Policy recommendations are provided to address thesechallenges, emphasizing the need for simplified loan processes, enhanced financial literacy programs, andimproved outreach of formal financial institutions. Ultimately, this study underscores the importance ofagricultural credit as a key driver of productivity and economic stability for farmers in Rajasthan, suggestingthat strategic interventions can lead to sustainable growth in the agricultural sector.

description: We have measured a strictly linear pi-plasmon dispersion along the axis of individualized single wall carbon nanotubes, which is completely different from plasmon dispersions of graphite or bundled single wall carbon nanotubes. Comparative ab initio studies on graphene based systems allow us to reproduce the different dispersions. This suggests that individualized nanotubes provide viable experimental access to collective electronic excitations of graphene, and it validates the use of graphene to understand electronic excitations of carbon nanotubes. In particular, the calculations reveal that local field effects (LFE) cause a mixing of electronic transitions, including the 'Dirac cone', resulting in the observed linear dispersion.

description: No abstracts are to be cited without prior reference to the author. Fisheries managers are increasingly taking action to resolve unsustainable fishing practices, including for fisheries on data limited stocks (DLS). North Sea Horse mackerel has been categorised by ICES as a DLS and consequently has provided precautionary advice based on its recently developed DLS advisory framework. In contrast to many data rich stocks, which are nowadays often managed with multi‐annual plans, the future of DLS stocks is relatively unclear. In collaboration with industry stakeholders a proposal for a multi‐annual plan for North Sea horse mackerel was developed. The process included evaluating the currently available data, conducting exploratory stock assessments, analysing the behaviour of a set of candidate harvest control rules (HCRs) (both in hind‐  and forecasts) and identifying knowledge gaps and plans for resolving these shortcomings in the future.

description: We derive the full kinetic equations describing the evolution of the probability density distribution for a structured population such as cells distributed according to their ages and sizes. The kinetic equations for such a "sizer-timer" model incorporates both demographic and individual cell growth rate stochasticities. Averages taken over the densities obeying the kinetic equations can be used to generate a second order PDE that incorporates the growth rate stochasticity. On the other hand, marginalizing over the densities yields a modified birth-death process that shows how age and size influence demographic stochasticity. Our kinetic framework is thus a more complete model that subsumes both the deterministic PDE and birth-death master equation representations for structured populations.

The use of the resistivity piezocone (RCPTU) for the geoenvironmental characterization of sulphide bearing tailings and native soils
Creators: name: Boyd, Timothy John
Publisher: name: University of British Columbia
Year: 2009

description: Recent advances in the in-situ testing of sulphide bearing mine tailings have included the development of a resistivity piezocone (RCPTU) and improved water sampling technologies. The RCPTU measures the bulk resistivity of the soil, in addition to all other standard piezocone (CPTU) measurements. The bulk resistivity profile permits assessment of pore water chemistry with correlation to pore water samples and the standard CPTU measurements give accurate estimates of stratigraphy and key geotechnical parameters and hydrogeological characteristics. Also, use of the RCPTU in combination with discrete pore water sampling technologies can permit the development of relationships between bulk resistivity measurements and specific pore water constituents. The technology is repeatable, rapid and economical when compared to traditional drilling and sampling site investigation techniques. A significant area of concern in the mining industry is acid rock drainage (ARD). ARD is the contaminant drainage which results from oxidation of sulphide minerals and it can represent a serious hazard to surrounding surhcial and groundwater systems. The evolution of ARD creates elevated electrical conductivity of tailings pore water which can be readily detected by the RCPTU bulk resistivity measurements. In addition to environmental issues, there are significant geotechnical considerations in the construction of large dams for tailings storage. One fundamental consideration is the potential for a flow failure of the tailings impoundment due to liquefaction of the tailings under both static and dynamic loading conditions. There is a significant challenge in adequately characterizing these impoundments for their geochemical, hydrogeological and geotechnical nature. The potential to use a single procedure for determining many varied engineering design parameters is highly attractive. Results of a field testing program carried out at sulphide bearing tailings impoundments of three Canadian mines are presented with respect to environmental and geotechnical characterization issues. Site-specific relationships between bulk resistivity measurements and pore water chemistry are developed. CPTU data is used to assess hydrogeological characteristics at specific sites and estimate movement of ARD contaminated pore water. CPTU-based methods are used to assess the susceptibility of liquefaction of tailings, considering both static and dynamic load conditions. Finally, recommendations are made with regard to the use of the RCPTU as a component of an overall geoenvironmental characterization plan for the evaluation of sulphide bearing tailings impoundments.

Search for giant planets around seven white dwarfs in the Hyades cluster with the Hubble Space Telescope

description: Only a small number of exoplanets has been identified in stellar cluster environments. We initiated a high angular resolution direct imaging search using the Hubble Space Telescope (HST) and its NICMOS instrument for self-luminous giant planets in orbit around seven white dwarfs in the 625 Myr old nearby (45 pc) Hyades cluster. The observations were obtained with NIC1 in the F110W and F160W filters, and encompass two HST roll angles to facilitate angular differential imaging. The difference images were searched for companion candidates, and radially averaged contrast curves were computed. Though we achieve the lowest mass detection limits yet for angular separations >0.5 arcsec, no planetary mass companion to any of the seven white dwarfs, whose initial main sequence masses were >2.8 Msun, was found. Comparison with evolutionary models yields detection limits of 5 to 7 Jupiter masses according to one model, and between 9 and 12 Mjup according to another model, at physical separations corresponding to initial semimajor axis of >5 to 8 A.U. (i.e., before the mass loss events associated with the red and asymptotic giant branch phase of the host star). The study provides further evidence that initially dense cluster environments, which included O- and B-type stars, might not be highly conducive to the formation of massive circumstellar disks, and their transformation into giant planets (with m>6 Mjup and a>6 A.U.). This is in agreement with radial velocity surveys for exoplanets around G- and K-type giants, which did not find any planets around stars more massive than about 3 Msun.

description: We have used resonant inelastic x-ray scattering to reveal optical magnons in a honeycomb lattice iridate $α$-Li$_{2}$IrO$_{3}$. The spectrum in the energy region 20-25 meV exhibits momentum dependence, of which energy is highest at the location of the magnetic Bragg peak, ($\textit{h}, \textit{k}$) = ($\pm$0.32, 0), and lowered toward (0, 0) and ($\pm$1, 0). We compare our data with a linear spin-wave theory based on a generic nearest-neighbor spin model. We find that a dominant bond-directional Kitaev interaction of order 20 meV is required to explain the energy scale observed in our study. The observed excitations are understood as stemming from optical magnon modes whose intensity is modulated by a structure factor, resulting in the apparent momentum dependence. We also observed diffuse magnetic scattering arising from the short-range magnetic correlation well above $\textit{T}_{N}$. In contrast to Na$_{2}$IrO$_{3}$, this diffuse scattering lacks the $C_3$ rotational symmetry of the honeycomb lattice, suggesting that the bond anisotropy is far from negligible in $α$-Li$_{2}$IrO$_{3}$.

description: It is unclear how very close binary stars form, given that during the pre-main-sequence phase the component stars would have been inside each other. One hypothesis is that they formed further apart, but were brought in closer after formation by gravitational interaction with a third member of the system. If so, all close binaries should be members of triple (or higher-order) systems. As a test of this prediction, we present a search for the signature of third components in archival spectra of close binaries. In our sample of 75 objects, 23 show evidence for the presence of a third component, down to a detection limit of tertiary flux contributions of about 0.8% at 5200 Å (considering only contact and semi-detached binaries, we find 20 out of 66). In a homogeneous subset of 58 contact binaries, we are fairly confident that the 15 tertiaries we have detected are all tertiaries present with mass ratios $0.28\lesssim M_3/M_{12}\lesssim0.75$ and implied outer periods $P\lesssim10^6{\rm d}$. We find that if the frequency of tertiaries was the same as that of binary companions to solar-type stars, we would have expected to detect about 12 tertiaries. In contrast, if all contact binaries were in triple systems, one would expect about 20. Thus, our results are not conclusive, but sufficiently suggestive to warrant further studies.

description: The recent release of the second Gravitational-Wave Transient Catalog (GWTC-2) has increased significantly the number of known GW events, enabling unprecedented constraints on formation models of compact binaries. One pressing question is to understand the fraction of binaries originating from different formation channels, such as isolated field formation versus dynamical formation in dense stellar clusters. In this paper, we combine the $\texttt{COSMIC}$ binary population synthesis suite and the $\texttt{CMC}$ code for globular cluster evolution to create a mixture model for black hole binary formation under both formation scenarios. For the first time, these code bodies are combined self-consistently, with $\texttt{CMC}$ itself employing $\texttt{COSMIC}$ to track stellar evolution. We then use a deep-learning enhanced hierarchical Bayesian analysis to constrain the mixture fraction $f$ between formation models, while simultaneously constraining the common envelope efficiency $α$ assumed in $\texttt{COSMIC}$ and the initial cluster virial radius $r_v$ assumed in $\texttt{CMC}$. Under specific assumptions about other uncertain aspects of isolated binary and globular cluster evolution, we report the median and $90\%$ confidence interval of three physical parameters $(f,α,r_v)=(0.20^{+0.32}_{-0.18},2.26^{+2.65}_{-1.84},2.71^{+0.83}_{-1.17})$. This simultaneous constraint agrees with observed properties of globular clusters in the Milky Way and is an important first step in the pathway toward learning astrophysics of compact binary formation from GW observations.

description: No abstracts are to be cited without prior reference to the author. Evaluation of Harvest Control Rule (HCR) for golden redfish in the area East Greenland-IcelandFaeroe Islands is described. The operating model is size based, modelling growth, taking into account size selective removal of incoming cohorts. The observation model is true stock-size model multiplied by an autocorrelated lognormal error. The operating model is used to evaluate FMAX that is then used for target in the HCR. Stochastic simulations are conducted taking assessment error and variability in recruitment into account.

description: During the past years several variance reduction techniques for Monte Carlo electron transport have been developed in order to reduce the electron computation time transport for absorbed dose distribution. We have implemented the Macro Response Monte Carlo (MRMC) method to evaluate the electron spectrum which can be used used as a phase space input for others simulation programs. Such technique uses probability distributions for electron histories previously simulated in spheres (called kugels). These probabilities are used to sample the primary electron final state, as well as the creation secondary electrons and photons. We have compared the MRMC electron spectra simulated in homogeneous phantom against the Geant4 spectra. The results showed an agreement better than 6% in the spectra peak energies and that MRMC code is up to 12 times faster than Geant4 simulations.

On the origin of the solar hemispherical helicity rules: Simulations of the rise of magnetic flux concentrations in a background field

description: Solar active regions and sunspots are believed to be formed by the emergence of strong toroidal magnetic flux from the solar interior. Modeling of such events has focused on the dynamics of compact magnetic entities, colloquially known as "flux tubes", often considered to be isolated magnetic structures embedded in an otherwise field-free environment. In this paper, we show that relaxing such idealized assumptions can lead to surprisingly different dynamics. We consider the rise of tube-like flux concentrations embedded in a large-scale volume-filling horizontal field in an initially quiescent adiabatically-stratified compressible fluid. In a previous letter, we revealed the unexpected major result that concentrations that have their twist aligned with the background field at the bottom of the tube are more likely to rise than the opposite orientation (for certain values of the parameters). This bias leads to a selection rule which, when applied to solar dynamics, is in agreement with the observations known as the solar hemispheric helicity rule(s) (SHHR). Here, we examine this selection mechanism in more detail than was possible in the earlier letter. We explore the dependence on the parameters via simulations, delineating the Selective Rise Regime (SRR), where the bias operates. We provide a theoretical model to predict and explain the simulation dynamics. Furthermore, we create synthetic helicity maps from Monte Carlo simulations to mimic the SHHR observations and demonstrate that our mechanism explains the observed scatter in the rule and its variation over the solar cycle.

description: Systemic immunity plays an important role in cancer immune surveillance and response to therapy, but little is known about the immune status of children with solid cancers. We performed a high-dimensional single-cell analysis of systemic immunity in 50 treatment-naive pediatric cancer patients, comparing them to age-matched healthy children. Children with cancer had a lower frequency of peripheral NK cells, which was not due to tumor sequestration, had lower surface levels of activating receptors and increased levels of the inhibitory NKG2A receptor. Furthermore, the natural killer (NK) cells of pediatric cancer patients were less mature and less cytotoxic when tested in vitro. Culture of these NK cells with interleukin-2 restored their cytotoxicity. Collectively, our data show that NK cells in pediatric cancer patients are impaired through multiple mechanisms and identify rational strategies to restore their functionality.

description: In contract analysis and contract automation, a knowledge base (KB) of legal entities is fundamental for performing tasks such as contract verification, contract generation and contract analytic. However, such a KB does not always exist nor can be produced in a short time. In this paper, we propose a clustering-based approach to automatically generate a reliable knowledge base of legal entities from given contracts without any supplemental references. The proposed method is robust to different types of errors brought by pre-processing such as Optical Character Recognition (OCR) and Named Entity Recognition (NER), as well as editing errors such as typos. We evaluate our method on a dataset that consists of 800 real contracts with various qualities from 15 clients. Compared to the collected ground-truth data, our method is able to recall 84\% of the knowledge.

description: L’autore, dopo avere delineato qualche situazione problematica circa la formazione alla
vita consacrata negli ultimi 60 anni, specificamente dal concilio ad oggi, prospetta alcune
risorse ed opportunità contemporanee, che possono favorire una nuova presa di
coscienza per quanto riguarda la formazione nella stessa vita consacrata, in particolare
l’importanza dei modelli insieme ai valori, la riscoperta dell’identità, il senso di appartenenza,
la sfida dell’interculturalità e della comunicazione, la nuova visuale dei tradizionali
consigli evangelici. Di qui egli invita con fiducia ad una nuova posa in opera
della formazione, che si deve giocare nel circuito di una più stretta collaborazione tra
formatori/trici e formandi/e e in una interfaccia più collaborativa di interscambio tra
prima formazione e formazione continua, per una vera unità e armonia nella crescita
delle singole persone e delle fraternità. Un vero laboratorio di futuro.

description: No abstracts are to be cited without prior reference to the author. When individual transferable quotas (ITQ) systems are operating well, stocks rebuild and fleets become more efficient through the transfer of quota units to more efficient operators. Critically this process requires functional markets for quota units. When functioning, these markets are expected to respond to changes in economic rent from the fishery, which in turn is influenced by stock abundance. This research examined changes in the nature of quota trade in the Tasmanian rock lobster fishery quota market, during periods of increasing and decreasing stock abundance. Quota owners’ trading behaviour was investigated using Multi-state Markov models. The rate of permanent quota transference was driven by their quota ownership and holding, and influenced by stock abundance.

description: No abstracts are to be cited without prior reference to the author. Latvian fishery in the Baltic Sea is based on three main species – cod, sprat and herring. Sprat is one of the most abundant and commercially important fish species for Latvian fishermen. Sprat landings during 2000-2012 contributed about 60% to total Latvian catch. Understanding of specific nature of catch rate or catch per unit of effort (CPUE) parameter may be helpful for the improvement of fishery management.

description: Based on a first-principles approach, we present scaling rules for the band gaps of graphene nanoribbons (GNRs) as a function of their widths. The GNRs considered have either armchair or zigzag shaped edges on both sides with hydrogen passivation. Both varieties of ribbons are shown to have band gaps. This differs from the results of simple tight-binding calculations or solutions of the Dirac's equation based on them. Our {\it ab initio} calculations show that the origin of energy gaps for GNRs with armchair shaped edges arises from both quantum confinement and the crucial effect of the edges. For GNRs with zigzag shaped edges, gaps appear because of a staggered sublattice potential on the hexagonal lattice due to edge magnetization. The rich gap structure for ribbons with armchair shaped edges is further obtained analytically including edge effects. These results reproduce our {\it ab initio} calculation results very well.

description: Metal nanoparticles are receiving increased scientific attention owing to their unique physical and chemical properties that make them suitable for a wide range of applications in diverse fields, such as electrochemistry, biochemistry, and nanomedicine. Their high metallic polarizability is a crucial determinant that defines their electrostatic character in various electrolyte solutions. Here, we introduce a continuum-based model of a metal nanoparticle with explicit polarizability in the presence of different kinds of electrolytes. We employ several, variously sophisticated, theoretical approaches, corroborated by Monte Carlo simulations in order to elucidate the basic electrostatics principles of the model. We investigate how different kinds of asymmetries between the ions result in non-trivial phenomena, such as charge separation and a build-up of a so-called zero surface-charge double layer.

description: Inspired by his vanishing results of tautological classes and by Harer's computation of the virtual cohomological dimension of the mapping class group, Looijenga conjectured that the moduli space of smooth Riemann surfaces admits a stratification by affine subsets with a certain number of layers. Similarly, Roth and Vakil extended the conjecture to the moduli spaces of Riemann surfaces of compact type, of Riemann surfaces with rational tails and of Riemann surfaces with at most k rational components. As a consequence of Lefschetz's theorem, Roth-Vakil's conjecture would also imply that the previous (coarse) moduli spaces are homotopy equivalent to cellular complexes of a certain dimension. Using Harer's computation for the moduli spaces of smooth Riemann surfaces, we prove this last statement.
