description: Text tracking is to track multiple texts in a video,and construct a trajectory for each text. Existing methodstackle this task by utilizing the tracking-by-detection frame-work, i.e., detecting the text instances in each frame andassociating the corresponding text instances in consecutiveframes. We argue that the tracking accuracy of this paradigmis severely limited in more complex scenarios, e.g., owing tomotion blur, etc., the missed detection of text instances causesthe break of the text trajectory. In addition, different textinstances with similar appearance are easily confused, leadingto the incorrect association of the text instances. To this end,a novel spatio-temporal complementary text tracking model isproposed in this paper. We leverage a Siamese ComplementaryModule to fully exploit the continuity characteristic of the textinstances in the temporal dimension, which effectively alleviatesthe missed detection of the text instances, and hence ensuresthe completeness of each text trajectory. We further integratethe semantic cues and the visual cues of the text instance intoa unified representation via a text similarity learning network,which supplies a high discriminative power in the presence oftext instances with similar appearance, and thus avoids the mis-association between them. Our method achieves state-of-the-art performance on several public benchmarks. The source codeis available at https://github.com/lsabrinax/VideoTextSCM.

description: The linear response of a neutron spin-triplet superfluid onto external weak axial-vector field is studied for the case of $^{3}P_{2}$ pairing with a projection of the total angular momentum $m_{j}=0$. The problem is considered in the BCS approximation discarding Fermi-liquid effects. The anomalous axial-vector vertices of neutron quasiparticles possess singularities at some frequencies which specify existence of undamped spin-density waves in the Cooper condensate. The spin waves are of a low excitation energy and are kinematically able to decay into neutrino pairs through neutral weak currents. We evaluate the neutrino emissivity from the spin wave decays in the bulk neutron superfluid in old neutron stars. This calculation predicts significant energy losses from within a neutron star at lowest temperatures when all other mechanisms of neutrino emission are killed by the neutron and proton superfluidity.

description: Using the large $D$ effective theory approach, we construct a static solution of non-extremal and squashed black holes with/without an electric charge, which describes a spherical black hole in a Kaluza-Klein spacetime with a compactified dimension. The asymptotic background with a compactified dimension and near-horizon geometry are analytically solved by the $1/D$ expansion. Particularly, our work demonstrates that the large $D$ limit can be applied to solve the non-trivial background with a compactified direction, which leads to a first-order flow equation. Moreover, we show that the extremal limit consistently reproduces the known extremal result.

description: We discuss the existence of a conformal phase in SU(N) gauge theories in four dimensions. In this lattice study we explore the model in the bare parameter space, varying the lattice coupling and bare mass. Simulations are carried out with three colors and twelve flavors of dynamical staggered fermions in the fundamental representation. The analysis of the chiral order parameter and the mass spectrum of the theory indicates the restoration of chiral symmetry at zero temperature and the presence of a Coulomb-like phase, depicting a scenario compatible with the existence of an infrared stable fixed point at nonzero coupling. Our analysis supports the conclusion that the onset of the conformal window for QCD-like theories is smaller than Nf=12, before the loss of asymptotic freedom at sixteen and a half flavors. We discuss open questions and future directions.

description: RESUMO

O período gestacional é um fenômeno que causa grandes transformações físicas e psicológicas na vida de um casal, devido ao homem sair da posição de expectador e passar a ser presente, dando apoio e assistência, faz com que a gestante se sinta acolhida. Assim o presente trabalho tem o objetivo de identificar se as equipes de enfermagem entendem a importância da atuação paterna no pré-natal e se seus benefícios são conhecidos pela sociedade. Trata-se em uma pesquisa de revisão de literatura exploratória e descritiva, com abordagem qualitativa. Uma Pesquisa Nacional de Saúde de 2019 realizada pelo IBGE, demonstrou que 76,7% dos homens entrevistados relatou ter se envolvido no acompanhamento do pré-natal. Dentre desse índice relataram que 57% foram informados sobre a possibilidade de participar do parto. A presença do pai durante o pré-natal possibilita ao homem experimentar sentimentos de afeto, ajudando a formar um laço entre o pai, mãe e filho. Ademais, sua presença ajuda durante o parto e o período puerperal. Promovendo a troca de papéis onde o homem assume a responsabilidade de oferecer cuidados. Nesse contexto o papel do enfermeiro na assistência prestada ao companheiro, não é somente promover o envolvimento do parceiro, porém é o ato de realizar orientações de forma clara e sucinta afim de facilitar o seu entendimento sobre as mudanças emocionais e físicas que a gestante irá passar. Com isso sugere-se a necessidade de manter a continuidade de pesquisas nesta área, uma vez que tais dados são essenciais para aprimorar as estratégias de atenção à saúde do parceiro.

description: The amplitude of the primordial magnetic field (PMF) is constrained from observational limits on primordial nuclear abundances. Within this constraint, it is possible that nuclear motion is regulated by Coulomb scattering with electrons and positrons ($e^\pm$'s), while $e^\pm$'s are affected by a PMF rather than collisions. For example, at a temperature of $10^9$ K, thermal nuclei typically experience $\sim 10^{21}$ scatterings per second that are dominated by very small angle scattering leading to minuscule changes in the nuclear kinetic energy of order $\mathcal{O}$(1) eV. In this paper the upper limit on the effects of a possible discretization of the $e^\pm$ momenta by the PMF on the nuclear momentum distribution is estimated under the extreme assumptions that the momentum of the $e^\pm$ is relaxed before and after Coulomb scattering to Landau levels, and that during Coulomb scattering the PMF is neglected. This assumption explicitly breaks the time reversal invariance of Coulomb scattering, and the Maxwell-Boltzmann distribution is not a trivial steady state solution of the Boltzmann equation under these assumptions. We numerically evaluate the collision terms in the Boltzmann equation, and show that the introduction of a special direction in the $e^\pm$ distribution by the PMF generates no directional dependence of the collisional destruction term of nuclei. Large anisotropies in the nuclear distribution function are then constrained from big bang nucleosynthesis. Ultimately, we conclude that a PMF does not significantly affect the isotropy or BBN.

description: Această lucrare analizează calitatea mediului în Parcul Herăstrău, unul dintre cele mai importante spații verzi din București. Studiul evidențiază importanța parcurilor urbane pentru calitatea vieții și biodiversitate, subliniind rolul lor în reducerea poluării și îmbunătățirea condițiilor climatice locale.

Cercetarea se desfășoară pe mai multe niveluri: identificarea caracteristicilor biofizice și socio-economice ale parcului, evaluarea calității factorilor de mediu și analiza impactului surselor de degradare. Metodologia utilizată include prelevarea și analiza datelor privind aerul, apa, solul, poluarea fonică și starea vegetației, bazându-se pe măsurători directe, studii de specialitate și utilizarea tehnologiilor GIS.

Rezultatele indică faptul că poluarea aerului, cauzată în principal de traficul din zonele adiacente, prezintă variații sezoniere, fiind mai ridicată în lunile de iarnă. Calitatea apei Lacului Herăstrău este influențată de factori antropici, precum deversările de substanțe chimice și acumularea de nutrienți, conducând la dezechilibre ecologice. Poluarea fonică este determinată de traficul rutier și activitățile recreative, iar solul prezintă contaminări cu metale grele, provenite din activitatea urbană. Vegetația din parc joacă un rol important în filtrarea poluanților, însă se confruntă cu probleme legate de uscarea arborilor și prezența speciilor invazive.

Lucrarea subliniază necesitatea unor măsuri de management sustenabil pentru îmbunătățirea calității mediului, inclusiv reducerea surselor de poluare, monitorizarea continuă a factorilor de mediu și implementarea unor strategii eficiente de conservare a biodiversității. Aceste intervenții sunt esențiale pentru menținerea atractivității și funcționalității Parcului Herăstrău, în contextul urbanizării accelerate și al creșterii presiunii antropice asupra spațiilor verzi.

description: We present an update of the light meson spectrum with $N_f$=2+1 overlap fermions on a $16^3\times 48$ lattice at five different up and down quark masses and two strange quark masses. Based on our experience with the previous simulation with $N_f=2$, we carry out the chiral extrapolation with the prediction of the chiral perturbation theory at the next-to-next-to leading order. We also check the consistency of our analysis by using alternative chiral extrapolation with a reduced theory in which the strange quark mass is integrated out.

NGC 1850 BH1 is another stripped-star binary masquerading as a black hole

description: We show that the radial velocity-variable star in the black hole candidate NGC 1850 BH1 cannot be a normal $\approx 5\,M_{\odot}$ subgiant, as was proposed, but is an overluminous stripped-envelope star with mass $\approx 1 M_{\odot}$. The result follows directly from the star's observed radius and the orbital period -- density relation for Roche lobe-filling stars: the star's density, as constrained by the observed ellipsoidal variability, is too low for its mass to exceed $\approx 1.5\,M_{\odot}$. This lower mass significantly reduces the implied mass of the unseen companion and qualitative interpretation of the system, such that a normal main-sequence companion with mass $(2.5-5)\,M_{\odot}$ is fully consistent with the data. We explore evolutionary scenarios that could produce the binary using MESA and find that its properties can be matched by models in which a $\sim5\,M_{\odot}$ primary loses most of its envelope to a companion and is observed in a bloated state before contracting to become a core helium burning sdOB star. This is similar to the scenario proposed to explain the binaries LB-1 and HR 6819. Though it likely does not contain a black hole, NGC 1850 BH1 provides an interesting test case for binary evolution models, particularly given its membership in a cluster of known age.

Customer Evolution in Sales Channel Migration

description: This research has been triggered by an emergent trend in customer behavior: customers have rapidly expanded their channel experiences and preferences beyond traditional channels (such as stores) and they expect the company with which they do business to have a presence on all these channels. This evidence has produced an increasing interest in multichannel customer behavior and it has motivated several researchers to study the customers’ channel choices dynamics in multichannel environment. We study how the consumer decision process for channel choice and response to marketing communications evolves for a cohort of new customers. We assume a newly acquired customer’s decisions are described by a “trial” model, but the customer’s choice process evolves to a “post-trial” model as the customer learns his or her preferences and becomes familiar with the firm’s marketing efforts. The trial and post-trial decision processes are each described by different multinomial logit choice models, and the evolution from the trial to post-trial model is determined by a customer-level geometric distribution that captures the time it takes for the customer to make the transition. We utilize data for a major retailer who sells in three channels – retail store, the Internet, and via catalog. The model is estimated using Bayesian methods that allow for cross-customer heterogeneity. This allows us to have distinct parameters estimates for a trial and an after trial stages and to estimate the quickness of this transit at the individual level. The results show for example that the customer decision process indeed does evolve over time. Customers differ in the duration of the trial period and marketing has a different impact on channel choice in the trial and post-trial stages. Furthermore, we show that some people switch channel decision processes while others don’t and we found that several factors have an impact on the probability to switch decision process. Insights from this study can help managers tailor their marketing communication strategy as customers gain channel choice experience. Managers may also have insights on the timing of the direct marketing communications. They can predict the duration of the trial phase at individual level detecting the customers with a quick, long or even absent trial phase. They can even predict if the customer will change or not his decision process over time, and they can influence the switching process using specific marketing tools

Unitarietà della successione mortis causa, successioni anomale e separate, alla luce delle recenti evoluzioni legislative
Creators: name: Buldini, Alberto <1982>
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2009
Subjects: IUS/01 Diritto privato

description: L'Autore opera una ricostruzione teorica del concetto di unità della successione, apprezzandone diverse sfumature: un significato più ristretto, per cui esso si lega al concetto di universitas ed individua appunto come unico il complesso delle situazioni giuridiche soggettive riferibili al de cuius; un secondo concetto più ampio, per cui unitarietà della successione mortis causa è il fenomeno per cui la successione nella somma delle posizioni giuridiche spettanti al defunto riceve una unica regolazione legislativa; un terzo profilo, che abbandona il concetto di successione mortis causa in senso giuridico, per accostarsi ad un concetto (piuttosto di natura economica)di unità della vicenda successoria.
Se il concetto di unità della successione possiede un triplice, valore, anche la deroga ad esso potrà assumere diverse vesti, a seconda che incida sul primo, sul secondo o sul terzo di questi significati. Se il terzo profilo riguarda piuttosto un concetto economico e non tecnico di successione, ed importa conseguentemente deroghe solo indirette all’unità della successione, l’anomalia può essere di due tipi: possono essere dettate regole particolari per singoli beni, che però rimangono entro l’unica massa ereditaria, pur avendo una destinazione loro propria, e può invece essere creata dal legislatore una separata massa per cui si fa luogo ad una distinta regolazione successoria. Procedendo nella classificazione, le ipotesi di una deroga del primo tipo possono essere definite successioni speciali, riservando alla seconda classe di anomalie il nome di successioni separate.
Conclusivamente, l'autore rileva che la disciplina della vicenda successoria, così come consegnata dalla tradizione e sancita ancora nelle norme della codificazione del 1942, non è più caratterizzata dall’assoluto dominio del principio di unità della successione, anche perché non si è rivelata, nella esperienza giuridica successiva alla codificazione, del tutto adeguata, in relazione a determinate categorie di beni e ad alcune categorie di soggetti coinvolti. Il legislatore ha infatti ritenuto di introdurre deroghe, via via maggiori al principio, con riferimento sia ai beni d’impresa sia alla particolare posizione – ed agli interessi tutelati – dei soggetti più vicini al de cuius, come il coniuge ed i parenti che vivessero a suo carico.

The other part of the session is a demo starting from the Recent Changes feed. Abstract The way Wikidata bridges across many domains of knowledge makes it interesting as a component of education. Here, I will look at this from two main use cases: (i) basic digital and data literacy and domain-general knowledge, (ii) domain-specific literacy and knowledge. Use case i will be mainly discussed at about high school level, and use case ii at undergraduate university level. Zooming in on the latter, I will further distinguish between use cases that are closely related to data science (ii-a) or not (ii-b).

description: Thermalization of a longitudinally expanding color glass condensate with Bjorken boost invariant geometry is investigated within parton cascade BAMPS. Our main focus lies on the detailed comparison of thermalization, observed in BAMPS with that suggested in the Bottom-Up scenario. We demonstrate that the tremendous production of soft gluons via $gg \to ggg$, which is shown in the Bottom-Up picture as the dominant process during the early preequilibration, will not occur in heavy ion collisions at RHIC and LHC energies, because the back reaction $ggg\to gg$ hinders the absolute particle multiplication. Moreover, contrary to the Bottom-Up scenario, soft and hard gluons thermalize at the same time. The time scale of thermal equilibration in BAMPS calculations is of order $\as^{-2} (\ln \as)^{-2} Q_s^{-1}$. After this time the gluon system exhibits nearly hydrodynamic behavior. The shear viscosity to entropy density ratio has a weak dependence on $Q_s$ and lies close to the lower bound of the AdS/CFT conjecture.

description: This thesis focuses on the limits that may prevent an entrepreneur from maximizing her value, and the benefits of diversification in reducing her cost of capital. After reviewing all relevant literature dealing with the differences between traditional corporate finance and entrepreneurial finance, we focus on the biases occurring when traditional finance techniques are applied to the entrepreneurial context. In particular, using the portfolio theory framework, we determine the degree of under-diversification of entrepreneurs. Borrowing the methodology developed by Kerins et al. (2004), we test a model for the cost of capital according to the firms' industry and the entrepreneur's wealth commitment to the firm. This model takes three market inputs (standard deviation of market returns, expected return of the market, and risk-free rate), and two firm-specific inputs (standard deviation of the firm returns and correlation between firm and market returns) as parameters, and returns an appropriate cost of capital as an output. We determine the expected market return and the risk-free rate according to the huge literature on the market risk premium. As for the market return volatility, it is estimated considering a GARCH specification for the market index returns. Furthermore, we assume that the firm-specific inputs can be obtained considering new-listed firms similar in risk to the firm we are evaluating. After we form a database including all the data needed for our analysis, we perform an empirical investigation to understand how much of the firm's total risk depends on market risk, and which explanatory variables can explain it. Our results show that cost of capital declines as the level of entrepreneur's commitment decreases. Therefore, maximizing the value for the entrepreneur depends on the fraction of entrepreneur's wealth invested in the firm and the fraction she sells to outside investors. These results are interesting both for entrepreneurs and policy makers: the former can benefit from an unbiased model for their valuation; the latter can obtain some guidelines to overcome the recent financial market crisis.

description: The spontaneous relaxation rates for an atom in free space and close to an absorbing surface are calculated to various orders of the electromagnetic multipole expansion. The spontaneous decay rates for dipole, quadrupole and octupole transitions are calculated in terms of their respective primitive electric multipole moments and the magnetic relaxation rate is calculated for the dipole and quadrupole transitions in terms of their respective primitive magnetic multipole moments. The theory of electromagnetic field quantization in magnetoelectric materials is used to derive general expressions for the decay rates in terms of the dyadic Green function. We focus on the decay rates in free space and near an infinite half space. For the decay of atoms near to an absorbing dielectric surface we find a hierarchy of scaling laws depending on the atom-surface distance z.

description: Due to their unique set of multimessenger signals, neutron star mergers have emerged as a novel environment for studies of new physics beyond the Standard Model (SM). As a case study, we consider the simplest extension of the SM scalar sector involving a light CP-even scalar singlet $S$ mixing with the SM Higgs boson. These $S$ particles can be produced abundantly in neutron star mergers via the nucleon bremsstrahlung process. We show that the $S$ particles may either be trapped in or stream freely out of the merger remnant, depending on the $S$ mass, its mixing with the SM Higgs boson, and the temperature and baryon density in the merger. In the free-streaming region, the scalar $S$ will provide an extra channel to cool down the merger remnant, with cooling timescales as small as ${\cal O}$(ms). On the other hand, in the trapped region, the Bose gas of $S$ particles could contribute a larger thermal conductivity than the trapped neutrinos in some parts of the parameter space, thus leading to faster thermal equilibration than expected. Therefore, future observations of the early postmerger phase of a neutron star merger could effectively probe a unique range of the $S$ parameter space, largely complementary to the existing and future laboratory and supernova limits. In view of these results, we hope the merger simulation community will be motivated to implement the effects of light CP-even scalars into their simulations in both the free-streaming and trapped regimes.

description: In the context of “testing laboratory” one of the most important aspect to deal with is the measurement result. Whenever decisions are based on measurement results, it is important to have some indication of the quality of the results. In every area concerning with noise measurement many standards are available but without an expression of uncertainty, it is impossible to judge whether two results are in compliance or not. 
ISO/IEC 17025 is an international standard related with the competence of calibration and testing laboratories. It contains the requirements that testing and calibration laboratories have to meet if they wish to demonstrate that they operate to a quality system, are technically competent and are able to generate technically valid results. ISO/IEC 17025 deals specifically with the requirements for the competence of laboratories performing testing and calibration and for the reporting of the results, which may or may not contain opinions and interpretations of the results. The standard requires appropriate methods of analysis to be used for estimating uncertainty of measurement.
In this point of view, for a testing laboratory performing sound power measurement according to specific ISO standards and European Directives, the measurement of uncertainties is the most important factor to deal with.
Sound power level measurement, according to ISO 3744:1994 , performed with a limited number of microphones distributed over a surface enveloping a source is affected by a certain systematic error and a related standard deviation. Making a comparison of measurement carried out with different microphone arrays is difficult because results are affected by systematic errors and  standard deviation that are peculiarities of the number of microphones disposed on the surface, their spatial position and the complexity of the sound field. A statistical approach could give an overview of the difference between sound power level evaluated with different microphone arrays and an evaluation of errors that afflict this kind of measurement. Despite the classical approach that tend to follow the ISO GUM this thesis present a different point of view of the problem related to the comparison of result obtained from different microphone arrays.
Gli effetti degli investimenti in R&S sulla produttività: il caso dell'industria alimentare italiana

description: Tutte le scuole di pensiero economico riconoscono l’importanza dell’attività di ricerca e sviluppo per rafforzare la competitività delle imprese, e per promuovere quindi la crescita economica di lungo periodo di ogni paese. 
Si tratta di un tema di indiscussa rilevanza, e ben presente nel dibattito politico ed economico a livello nazionale ed internazionale.
A partire dal fondamentale lavoro di Solow (1957), molti studi si sono interessati al ruolo centrale che il cambiamento tecnologico ha nella crescita economica, contribuendo ad una vasta letteratura riguardante il rapporto tra il capitale tecnologico, o gli investimenti in ricerca e sviluppo, e la crescita della produttività.
In questo contesto, il presente lavoro ha come obiettivo l’analisi degli effetti degli investimenti in ricerca e sviluppo sulla produttività delle imprese manifatturiere e del settore agroalimentare italiano.
L’industria agroalimentare italiana è caratterizzata da alcuni elementi specifici, che ne rendono lo studio particolarmente interessante: il suo necessario confrontarsi con le pressioni provenienti dall’emergere di nuove tendenze comportamentali del consumatore, da un lato e, dall’altro, dalla radicale trasformazione del sistema produttivo, commerciale e distributivo, che a sua volta si interfaccia con il processo di globalizzazione che interessa l’intera economia mondiale.
Il settore agroalimentare riveste nel nostro Paese una notevole importanza sia in termini di fatturato, che per numero di imprese, che di occupazione, e risulta tipicamente caratterizzato dalla predominanza, dal punto di vista numerico, della classe dimensionale delle piccole imprese.
È chiaro che acquisire competitività su mercati ormai globali presuppone costanti sforzi negli investimenti in ricerca ed innovazione; tuttavia, a questo proposito, le performances italiane risultano essere inferiori alla media europea. 
È proprio alla luce di queste considerazioni che uno studio sul ruolo che gli investimenti in ricerca e sviluppo rivestono nel sistema agroalimentare italiano, in rapporto a quanto avviene per l’intero settore manifatturiero, riveste quindi un particolare interesse.

description: Background: The phytopatogen Claviceps paspali is the causal agent of Ergot disease in Paspalum spp., which includes highly productive forage grasses such as P. dilatatum. This disease impacts dairy and beef production by affecting seed quality and producing mycotoxins that can affect performance in feeding animals. The molecular basis of pathogenicity of C. paspali remains unknown, which makes it more difficult to find solutions for this problem. Secreted proteins are related to fungi virulence and can manipulate plant immunity acting on different subcellular localizations. Therefore, identifying and characterizing secreted proteins in phytopathogenic fungi will provide a better understanding of how they overcome host defense and cause disease. The aim of this work is to analyze the whole genome sequences of three C. paspali isolates to obtain a comparative genome characterization based on possible secreted proteins and pathogenicity factors present in their genome. In planta RNA-seq analysis at an early stage of the interaction of C. paspali with P. dilatatum stigmas was also conducted in order to determine possible secreted proteins expressed in the infection process. Results: C. paspali isolates had compact genomes and secretome which accounted for 4.6–4.9% of the predicted proteomes. More than 50% of the predicted secretome had no homology to known proteins. RNA-Seq revealed that three protein-coding genes predicted as secreted have mayor expression changes during 1 dpi vs 4 dpi. Also, three of the first 10 highly expressed genes in both time points were predicted as effector-like. CAZyme-like proteins were found in the predicted secretome and the most abundant family could be associated to pectine degradation. Based on this, pectine could be a main component affected by the cell wall degrading enzymes of C. paspali. Conclusions: Based on predictions from DNA sequence and RNA-seq, unique probable secreted proteins and probable pathogenicity factors were identified in C. paspali isolates. This information opens new avenues in the study of the biology of this fungus and how it modulates the interaction with its host. Knowledge of the diversity of the secretome and putative pathogenicity genes should facilitate future research in disease management of Claviceps spp.

description: Skeletal muscle possesses the remarkable capacity to complete a rapid and extensive regeneration, even following severe damage. The regenerative ability of skeletal muscle relies on Satellite Cells (SCs), a population of muscle specific adult stem cells. However, during aging or under several pathological conditions, the ability of skeletal muscle to fully regenerated is compromised. Here, a morphological and molecular study on SCs from patients affected by ALS is described. Moreover, the role of the cell cycle regulator P16Ink4a during skeletal muscle regeneration and aging has been investigated.

description: With the rise of AI-generated code, programming courses face
new challenges in detecting code plagiarism. Traditional methods
struggle against obfuscation techniques that modify code structure
through statement insertion and deletion. To address this, we propose
a novel approach based on tolerant token matching designed
to enhance resilience against such attacks.We evaluate our method
through three experiments on a real-life dataset with AI-obfuscated
plagiarisms. The results show that our approach increased the median
similarity gap between originals and plagiarisms by 1 to 6
percentage points.

description: A multiband empirical tight-binding model for group-III-nitride semiconductors with a wurtzite structure has been developed and applied to both bulk systems and embedded quantum dots. As a minimal basis set we assume one s-orbital and three p-orbitals, localized in the unit cell of the hexagonal Bravais lattice, from which one conduction band and three valence bands are formed. Non-vanishing matrix elements up to second nearest neighbors are taken into account. These matrix elements are determined so that the resulting tight-binding band structure reproduces the known Gamma-point parameters, which are also used in recent kp-treatments. Furthermore, the tight-binding band structure can also be fitted to the band energies at other special symmetry points of the Brillouin zone boundary, known from experiment or from first-principle calculations. In this paper, we describe details of the parametrization and present the resulting tight-binding band structures of bulk GaN, AlN, and InN with a wurtzite structure. As a first application to nanostructures, we present results for the single-particle electronic properties of lens-shaped InN quantum dots embedded in a GaN matrix.

description: We present an efficient expression for the analytic continuation to arbitrary complex frequencies of the complex optical and AC conductivity of a homogeneous superconductor with arbitrary mean free path. Knowledge of this quantity is fundamental in the calculation of thermodynamic potentials and dispersion energies involving type-I superconducting bodies. When considered for imaginary frequencies, our formula evaluates faster than previous schemes involving Kramers--Kronig transforms. A number of applications illustrates its efficiency: a simplified low-frequency expansion of the conductivity, the electromagnetic bulk self-energy due to longitudinal plasma oscillations, and the Casimir free energy of a superconducting cavity.
