description: We investigate the accurate full broadband simulation of complex nonlinear optical processes. A mathematical model and numerical simulation techniques in the time domain are developed to simulate complex nonlinear optical processes without the usual used slowly varying envelope approximation. We illustrate the accuracy by numerical simulations. Furthermore, they are used to elucidate THz generation in periodically poled Lithium Niobate (PPLN) including optical harmonic generation.

description: O trabalho, realizado no âmbito do mestrado em Lusofonia e Relações Internacionais, começa com uma investigação sobre a História do Cristianismo em Angola, marcada por relações de apoios e de contestações ao governo colonial português que, em 1940, tinha assinado o Acordo Missionário com o Vaticano. O lançamento, em Luanda, da revista Mensagem (1951) e o início da luta armada(1961) vão dar visibilidade à consciência nacionalista em Angola e criar algumas rupturas entre o Estado e as Igrejas, com perseguições e exílio para alguns cristãos nacionalistas.O papa Paulo VI daria um primeiro sinal de apoio à causa das independências nas ‘Colónias’ portuguesas, quando recebeu, em 1970, Agostinho Neto, Amílcar Cabral e Marcelino dos Santos. Pastores e padres envolveram-se num processo imparável que viria a ter como ponto de chegada a independência nacional a 11 de Novembro de 1975.

description: Recent evidence suggests that neutrophils are highly plastic cells that can display heterogeneous phenotypes. Low-density neutrophils (LDNs) have been described in many inflammatory conditions, and are thought to represent an immature, hyperactivated subtype of neutrophils. Neutrophils are significantly involved in the inflammatory response to myocardial infarction (MI), although we do not know the extent to which LDNs exist, or function, in MI. This study sought to determine the frequency and phenotype of LDNs in MI patients, compared to healthy subjects (HS). LDNs and normal-density neutrophils (NDNs) were isolated from the peripheral blood of MI subjects (n = 12) and HSs (n = 12) using density gradient centrifugation. LDNs and NDNs were analysed by flow cytometry to identify neutrophils (CD66b+CD15+CD14-CD3−CD19− cells) and examine neutrophil activation (CD11b, CD66b and CD15) and maturity (CD33 and CD16). We identified LDNs within the peripheral blood mononuclear cell (PBMC) fraction of blood, and this population is significantly enriched in MI patients (1.04 ± 0.75% of PBMCs), compared to HS (0.29 ± 0.24%, p = .003). Across both cohorts, LDNs express significantly higher levels of CD66b and CD15, indicating a heightened state of activation compared to NDNs. In this study, LDNs were described as CD33highCD16low, compared to CD33lowCD16high NDNs, indicating the immaturity of this neutrophil subtype. An increase in the frequency of hyperactivated, immature LDNs is an immunological feature of MI. We highlight a potential pathological role of LDNs in MI, which underscores the need to expand our current understanding of this subtype in MI and other cardiovascular diseases (CVDs).

description: We present the results for the associated production of Higgs boson with vector boson computed at threshold N$^3$LO in QCD. We use the recently available result on the threshold contributions to the inclusive Drell-Yan production cross-section at third order in strong coupling constant. We have implemented it in the publicly available computer package vh@nnlo, thereby obtaining the numerical impact of threshold N$^3$LO contributions for the first time. We find that the inclusion of such corrections do reduce theoretical uncertainties resulting from the renormalization scale.

description: Drug use and problems change dramatically over time in ways that are often described
as reflecting an “epidemic cycle”. We use simulation of a model of drug epidemics to
investigate how the relative effectiveness of different types of prevention varies over the course
of such an epidemic. Specifically we use the so-called LHY model (see Behrens et al., 2000b)
which includes both “contagious” spread of initiation (a positive feedback) and memory of past
use (a negative feedback), which dampens initiation and, hence, future use. The analysis confirms
the common sense intuition that prevention is more highly leveraged early in an epidemic,
although the extent to which this is true in this model is striking, particularly for campaigns designed
to leverage awareness of the drug’s dangers. The findings also suggest that the design of
“secondary” prevention programs should change over the course of an epidemic.

description: We demonstrate that due to strong modal interactions through cross-gain saturation, the onset of a new lasing mode can switch off an existing mode via a negative power slope. In this process of interaction-induced mode switching (IMS) the two involved modes maintain their identities, i.e. they do not change their spatial field patterns or lasing frequencies. For a fixed pump profile, a simple analytic criterion for the occurrence of IMS is given in terms of their self- and cross-interaction coefficients and non-interacting thresholds, which is verified for the example of a two-dimensional microdisk laser. When the spatial pump profile is varied as the pump power is increased, IMS can be induced even when it would not occur with a fixed pump profile, as we show for two coupled laser cavities. Our findings apply to steady-state lasing and are hence different from dynamical mode switching or hopping. IMS may have potential applications in robust and flexible all-optical switching.

description: Superconducting nanowire single photon detectors are rapidly emerging as a key infrared photon-counting technology. Two front-side-coupled silver dipole nanoantennas, simulated to have resonances at 1480 nm and 1525 nm, were fabricated in a two-step process. An enhancement of 50% to 130% in the system detection efficiency was observed when illuminating the antennas. This offers a pathway to increasing absorption into superconducting nanowires, creating larger active areas, and achieving more efficient detection at longer wavelengths.

description: In this paper, we investigate the André/Bruck-Bose representation of certain $\mathbb{F}_q$-linear sets contained in a line of $\text{PG}(2,q^t)$. We show that scattered $\mathbb{F}_q$-linear sets of rank $3$ in $\text{PG}(1,q^3)$ correspond to particular hyperbolic quadrics and that $\mathbb{F}_q$-linear clubs in $\text{PG}(1,q^t)$ are linked to subspaces of a certain $2$-design based on normal rational curves; this design extends the notion of a circumscribed bundle of conics. Finally, we use these results to construct optimal higgledy-piggledy sets of planes in $\text{PG}(5,q)$.

Nesse sentido, a dimensão ética passa a ter grande relevância no campo da produção do conhecimentoe da escrita da história. E, os historiadores situados nessa dimensão têm demonstrado que não estão preocupados apenas em se relacionar com seu objeto e fontes, mas em justificar seu lugar social e institucional, procurando reconhecer que averdade é verdade historicamente reconhecida pelos seus pares num dado momento e lugar. Trataremos, enfim, de despertar algumas reflexões com o objetivo de indicaros avanços no sentido de uma democratização na legitimação do conhecimento histórico.

description: The very existence and purpose of street gangs is predicated on having an external threat or enemy. It is also recognized that gangs form allies as well as rivals with other gangs. The fact that gangs are embedded in an intricate structure of both positive (ally) and negative (rivalry) relationships has rarely been explored in terms of understanding the levels and the patterns of gang violence. In this paper, we use structural balance theory along with its applications in the international relations literature to examine whether certain triadic structures in which two rival gangs i and j are related to a third gang with either an ally or rival relationship is linked to the levels of violence that i will inflict upon j. We analyze the data on inter-gang relations and violent incidents among the gangs in Long Beach, CA using multiple regression quadratic assignment procedure (MRQAP). Our results indicate that the actual violent incidents between two rival gangs are not only the product of their feuding relationships but also the third gangs and the nature of their relationship with the two gangs. The results can potentially contribute to the formulation of effective strategy to manage gang violence and allocate law enforcement resources to gang conflicts that are likely to escalate.

description: A singularidade do relacionamento entre, por um lado, o reino do Kongo e as regiões mbundu vizinhas e, por outro, a acção evangelizadora levada a cabo pelos missionárioseuropeus desde o final do século XV é, hoje, largamente reconhecida. Com pontos de partida diversos e enquadramentos conceptuais por vezes distintos, a generalidade dos autores converge na ideia que, ao longo dos séculos, as cosmologias africanas seleccionaram e reinterpretaram símbolos e rituais cristãos sem que a sua solidez e coerência tenham sido abaladas. Contudo, se existe acordo em relação a essa realidade, o mesmo não pode dizer-se relativamente à identificação da natureza e importância dos factores que intervieram nesse processo. Um desses aspectos remete, segundo alguns autores, para a feição tolerante que a acção missionária teria assumido naquelas paragens, permitindo a compatibilização dos preceitos doutrinais cristãos com as práticas culturais daqueles povos. O texto que se segue procura reflectir sobre esta problemática, sugerindo uma outra abordagem aos relatos e demais registos documentais produzidos pelos missionários. Centra-se, em particular, no exame de um conjunto de regras metodológicas para a acção dos missionários no Kongo e em Angola compiladas por Giuseppe Monari, um missionário capuchinho de Modena que chegou a Luanda no início de 1713. A partir desta análise, procura-se sustentar a tese de que a acção missionária em África não pode ser desligada das representação sobre África e os africanos correntes na Europa e do modo como essas imagens evoluem no contexto da experiência vivencial do missionário na realidade africana. Nessa perspectiva, a evangelização dos africanos é pensada, não sobre uma visão tolerante da realidade cultural africana mas, ao invés, a partir de uma imagem que inferioriza os africanos e reduz a sua existência espiritual a um território de ilusão e aparência, dominado pelas forças volúveis do interesse e da paixão.

description: We use the 1996 Medical Expenditure Panel Survey to estimate a model of
household demand for employer-based health insurance, explicitly investigating
differences in behavior between households with two potential sources of coverage and
those with one source. Own and cross-price elasticities are estimated for three types of
health plans, including exclusive provider organizations, any provider organizations, and
mixed provider organizations. We find that the premium, family size, income, and
wealth significantly affect demand. Our elasticity estimates reveal an overall, small
behavioral response to changes in price with respect to health plan switching and take-up.
Finally, we discuss the implications of our findings with respect to employer benefit
design.

description: The ultrafast conversion of electrical to optical signals at the nanoscale is of fundamental interest for data processing, telecommunication and optical interconnects. However, the modulation bandwidths of semiconductor LEDs are limited by the spontaneous recombination rate of electron-hole pairs and the footprint of electrically-driven ultrafast lasers is too large for practical on-chip integration. A metal-insulator-metal (MIM) tunnel junction approaches the ultimate size limit of electronic devices and its operating speed is fundamentally limited only by the tunneling time. Here we study the conversion of electron energy - localized in vertical gold-h-BN-gold tunnel junctions - into free space photons, mediated by resonant slot antennas. Optical antennas efficiently bridge the size-mismatch between nanoscale volumes and far-field radiation and strongly enhance the electron-photon conversion efficiency. We achieve polarized, directional and resonantly enhanced light emission from inelastic electron tunneling and establish a novel platform for studying the interaction of electrons with strong electromagnetic fields. Our results pave the way for the further development of nanoscopic sources of light enabled by the combination of nanophotonic design principles and nanoelectronics.

description: Given data on a large network, this paper provides a framework for identification of preferences under the assumption of pairwise stability of network links. Network data present difficulties for identification, especially when one allows for links between nodes in a network to be interdependent; e.g., where friends of friends matter. Given a preference specification, we use the observed proportions of various possible payoff-relevant local network structures to learn about the underlying parameters. We show how one can map the observed proportions of these local structures to sets of parameters that are consistent with the model and the data. Our main result provides necessary conditions for a set of parameters to contain the identified set, under general specifications of preferences. We also provide sufficient conditions—and hence a characterization of the identified set—for two empirically relevant classes of specifications. The paper then provides a quadratic programming algorithm that can be used to construct the identified sets. This algorithm is illustrated in a set of Monte Carlo experiments.

description: Objectives Using violent crime data from Pittsburgh, Pennsylvania we investigate the performance of an “early warning system” (EWS) for starting/stopping police deployments to hot spots for crime prevention. We show that (1) even the hottest chronic hot spots are dynamic with months “on” and “off” and (2) temporary hot spots are also targets for prevention. We compare the performance of EWS to constant deployment at chronic hot spots.
Methods We estimate chronic hot spots using kernel density smoothing. We use simple methods for implementing EWS rules for detecting flare-ups, predicting persistence of flare-ups, and stopping deployments. Using 2000–2010 data we run computational experiments varying size of hot spots and rule thresholds to tune EWS.
Results Tradeoff curves with crimes exposed to prevention efforts versus area of the city under prevention workload show that static and dynamic deployments have nearly the same efficiency. Different, however, is land-use distribution. While chronic hot spots tend to be in or adjacent to commercial areas, dynamic hot spots have significantly more and widely-scattered residential locations. We argue that dynamic hot spots thus have higher potential for reducing fear of crime and providing responsive police services to neighborhoods.
Conclusions Even though police resources are “wasted” during “off” months by constant deployment to chronic hot spots, a dynamic system of deployment with simple methods cannot improve the efficiency of crime prevention. EWS comparably “wastes” resources because of false positives for hot-spot persistence and waiting to confirm hot-spot extinguishment. Nevertheless, EWS is more responsive to residential crime

description: The pedestrian trajectory prediction task is an essential component of intelligent systems. Its applications include but are not limited to autonomous driving, robot navigation, and anomaly detection of monitoring systems. Due to the diversity of motion behaviors and the complex social interactions among pedestrians, accurately forecasting their future trajectory is challenging. Existing approaches commonly adopt GANs or CVAEs to generate diverse trajectories. However, GAN-based methods do not directly model data in a latent space, which may make them fail to have full support over the underlying data distribution; CVAE-based methods optimize a lower bound on the log-likelihood of observations, which may cause the learned distribution to deviate from the underlying distribution. The above limitations make existing approaches often generate highly biased or inaccurate trajectories. In this paper, we propose a novel generative flow based framework with dual graphormer for pedestrian trajectory prediction (STGlow). Different from previous approaches, our method can more precisely model the underlying data distribution by optimizing the exact log-likelihood of motion behaviors. Besides, our method has clear physical meanings for simulating the evolution of human motion behaviors. The forward process of the flow gradually degrades complex motion behavior into simple behavior, while its reverse process represents the evolution of simple behavior into complex motion behavior. Further, we introduce a dual graphormer combining with the graph structure to more adequately model the temporal dependencies and the mutual spatial interactions. Experimental results on several benchmarks demonstrate that our method achieves much better performance compared to previous state-of-the-art approaches.

description: Procedemos a um faseamento dos acontecimentos que envolveram, directa ou indirectamente, o martírio da Rainha Santa Ketevan, para um melhor análise e entendimento dos mesmos. Deste modo identificamos quatro capítulos distintos, correspondentes no seu conjunto a uma baliza cronológica que vai de 1613 a 1628, ou se quisermos da tentativa de conquista do Gorgistão pelo rei Xá Abbas da Pérsia, até à colocação de parte das relíquias na Igreja do Convento da Graça, em Goa. A tentativa de conquista do Gorgistão pelo rei da Pérsia e, o consequente esforço diplomático por parte do rei Tamaraschan, com o envio de uma embaixada à Pérsia, para a qual foi convidada a rainha Guativanda de Dopoli, corresponde a uma primeira fase dos aconteci men tos, seguindo-se uma segunda, caracterizada pelo seu cativeiro na cidade de Xirás. Embora nenhuma das duas fases anteriores contemple o martírio e, consequentemente a distribuição das relíquias por diversos pontos do mundo cristão, ambas ajudam a compreender melhor o enredo que antecede e, que de certo modo, tem como deselace a sua morte. O martírio ocorrido no ano de 1624, a descoberta do corpo só teve lugar em Janeiro do ano seguinte, graças aos religiosos de Santo Agostinho - traduz um capítulo autónomo, fundamental no contexto da presente investigação, exigindo por isso uma análise mais cuidada de todos os acontecimentos posteriores. Segue-se por fim o quarto e ultimo capítulo, no qual se identifica a distribuição feita (pelos religiosos da referida Ordem) das relíquias da Rainha Santa Ketevan, levada acabo nomeadamente no Gorgistão e em Goa, então o “cérebro” de toda a Cristandade no Oriente.

description: Novel quantization properties related to the state vectors and the energy spectrum of a two-dimensional system of free particles are obtained in the framework of noncommutative (NC) quantum mechanics (QM) supported by the Weyl-Wigner formalism. Besides reproducing the magnetic field aspect of a Zeeman-like effect, the momentum space NC parameter introduces mutual information properties quantified by the quantum purity related to the relevant coordinates of the corresponding Hilbert space. Supported by the QM in the phase-space, the thermodynamic limit is obtained, and the results are extended to three-dimensional systems. The noncommutativity imprints on the thermodynamic variables related to free particles are identified and, after introducing some suitable constraints to fix an axial symmetry, the analysis is extended to two- and- three dimensional quantum rotor systems, for which the quantization aspects and the deviation from standard QM results are verified.

Corpus analysis

description: Corpora, i.e. collections of linguistic data (texts or conversations), are a fundamental asset of digital humanities research. A ubiquitous task for linguists is to explore linguistic questions in corpora: Which forms of the verb *to be* occur in a given text? Is it common that number words are preceded by articles? What types of phrase do occur as direct object in philosophical texts? What kinds of speech acts occur in modern conversations? What words can occur as hesitation markers in spoken modern German? Are texts by women longer (or shorter) than texts by men? To answer such questions, it is necessary to select and prepare data. We will discuss different approaches to compilation and annotation of corpora. Linguistic questions can only be approached if an adequate selection of texts is available; for instance, one will not find such evidence about conversational data in parliament speeches or mathematical papers. Hence, we will first be concerned with criteria and methods for compiling corpora: selecting texts based on extra- and intralinguistic criteria, including property rights. Linguistic data must be described by metadata, so that one can find e.g. utterances by female native speakers of Southern German in the second half of the 20th century about political developments in an informal setting. Approaches to metadata will be explored. It is often useful to annotate linguistic data with respect to: pragmatic structure such as speech acts or rhetorical relations; semantic elements, e.g. named entities or points in time; syntactic structures, e.g. dependencies or phrases; or morphological relations, e.g. by assigning parts of speech (*verb*, *noun*) or lemmatizing (reducing *lemmatizing* to *lemmatize*). Some of these annotations can be carried out (partly) automatically. We will discuss what tools exist and are available. The course will be mainly concerned with textual corpora, but as searching on speech or multimodal corpora is generally carried out on the transcription and annotation layers, it will also be useful to researchers dealing with such data.

Estudar o impacte do Cristianismo na China: confrontos por analogias versus saber ver

Year: 2013

description: O nosso propósito é reflectir objectivamente sobre a questão da identidade e da diferença entre a China e o Cristianismo, tomando como ponto de partida a obra de Jacques Gernet “Chine et Christianisme”. Ao analisar o confronto e o conhecimento a que a cultura europeia e a cultura chinesa foram sujeitas, nos sécs. XVI-XVIII, tentaremos de analisar a origem do equívoco de base que nos leva, ainda na nossa era, a não perceber a fundo o mundo chinês. Para este efeito, pretendo analisar a experiência histórica da missionação na China, protagonizada pela Companhia de Jesus, no intuito de evidenciar como a procura das semelhanças nos leva por vezes a criar malentendidos e a construir falsas identidades. Podemos afirmar com alguma segurança que, apesar de vivermos num mundo cada vez mais globalizante, estas circunstâncias permanecem identificáveis e perceptíveis,e que os equívocos e fricções culturais entre o Ocidente e o Oriente não pertencem apenas ao passado, fazendo parte integrante da presente conjuntura mundial.

description: We report the search results of muonic atoms from the STAR experiment at RHIC. The invariant mass distributions of hadron-muon pairs show peaks at the expected atom masses. Two particle correlation functions indicate the hadrons and muons that are close in phase space are emitted at the same space time point, which is a possible signature of muonic atom ionization at the beam pipe. The pion-muon correlation functions are further decomposed into two contributions, and the fraction of direct muons is obtained.

description: We present a high efficiency source of picosecond pulses derived from a dual cavity optical frequency comb generator. This approach overcomes the limitations of single cavity comb generators that are restricted to efficiencies of a few percent. We achieve picosecond pulses with GHz repetition rates offering over a hundred times higher output efficiency than a single cavity design and demonstrate tuning of pulse width by varying the modulation depth of the intra-cavity electro-optic modulator. These results provide a wavelength-agnostic design with a compact footprint for the development of portable picosecond pulsed laser systems for timing, metrology, and LIDAR applications.

description: Firearms are an important factor in violent crimes. Nationally, the percentage of violent offenses that involve use of a firearm closely tracks changes in the supply of newly manufactured pistols (Figure 1). As more pistols became available their use in violent crimes increased. After 1985, firearms were especially implicated in the dramatic rise in juvenile homicide rates, both as victims (Fingerhut, 1993; Fingerhut, et al., 1998) and offenders (Blumstein, 1995). While juvenile rates of homicides by gun surged upward, both adult and nongun juvenile homicide rates remained relatively flat during the same period (Blumstein and Cork, 1996; Cork, 1996). While the link between guns and youth homicides is compelling in aggregate data, very little is known about how gun availability actually affects individual behavior among youth, whether that effect differs between young adults and juveniles, and whether that relationship has changed over time. The research discussed here examines spatial and temporal features of crime guns in one city. The analysis focuses on attributes of crime guns and those who possess them, the geographic sources of those guns, the distribution of crime guns over neighborhoods in a city, and the relationship between the prevalence of crime guns and incidence of violent crimes especially homicides.

description: This paper describes an iterative method of per-pixel energy calibration of hybrid pixel detectors with GaAs:Cr sensor and Timepix readout chip. A convolution of precisely measured spectra of characteristic X-rays of different metals with the resolution and the efficiency of the pixel detector is used for the calibration. The energy resolution of the detector is also measured during the calibration. The use of per-pixel calibration allows to achieve a good energy resolution of the Timepix detector with GaAs:Cr sensor: 8% and 13% at 60 keV and 20 keV, respectively.
Primeiros missionários dominicanos portugueses no Oriente Lusíada

description: Segundo escritores dominicanos dos séculos XVII e XVIII, Fr. Jordão [de Évora] foi o primeiro frade dominicano português que foi para o Oriente, par aquela parte do mundo que iria estar sob o domínio do Império Português do Oriente. Foi para lá, em 1320, com um companheiro (socius) dominicano, Fr. Francisco de Pisis, e quatro frades franciscanos. O martírio de Fr. Jordão, em Taná, é descrito som tópicos neotestamentários, colhidos da Paixão de Cristo e do martírio de Estêvão, o Proto-Mártir. Depois da morte dele, os habitantes da região fizeram uma estátua de madeira coma sua efígie e adoraram-na até à chegada dos Portugueses àquela parte da Índia. Então, Fr. Aleixo de Setúbal, Prior de S. Domingos de Chaúl, levou-a para o seu Convento,onde continuou a ser venerada.

A refined threshold theorem for (1+2)-dimensional wave maps into surfaces

description: The recently established threshold theorem for energy critical wave maps states that wave maps with energy less than that of the ground state (i.e., a minimal energy nontrivial harmonic map) are globally regular and scatter on (1+2)-dimensional Minkowski space. In this note we give a refinement of this theorem when the target is a closed orientable surface by taking into account an additional invariant of the problem, namely the topological degree. We show that the sharp energy threshold for global regularity and scattering is in fact twice the energy of the ground state for wave maps with degree zero, whereas wave maps with nonzero degree necessarily have at least the energy of the ground state. We also give a discussion on the formulation of a refined threshold conjecture for the energy critical $SU(2)$ Yang-Mills equation on (1+4)-dimensional Minkowski space.

description: Explosive percolation in a network is a phase transition where a large portion of nodes becomes connected with an addition of a small number of edges. Although extensively studied in random network models and reconstructed real networks, explosive percolation has not been observed in a more realistic scenario where a network is generated by thresholding a similarity matrix describing between-node associations. In this report, I examine construction schemes of such thresholded networks, and demonstrate that explosive percolation can be observed by introducing edges in a particular order.
Heroin and Methamphetamine Seizures in Victoria, Australia: Purity Changes Associated with the Heroin “Drought”

description: The Australian heroin “drought” was a singular event deserving of the considerable scholarly attention it has engendered. The best way to understand market disruption is to examine both supply and demand side indicators, yet data on the former have been relatively neglected. Here we explore a rich data set on heroin and methamphetamine purity from 1998-2002 in Victoria that support monthly and even fortnightly time series. These series show that the drought was characterized by abrupt and substantial declines in heroin purity (from ~40% to as low as 10-15%), but those steep declines followed an extended period of substantial erosion in purity (from 70-75% in early 1999 to ~40% by the end of 2000). Purity rebounded from its post-drought lows but far from completely, stabilizing at ~20% for 2002. The heroin purity declines do not appear to stem from “cutting” at lower market levels. The declines did increase the purity variability per pure unit of heroin. There was no comparable evidence of contemporaneous effects in the methamphetamine purity series.

description: In this paper, we define general weighted cumulative residual extropy (GWCRJ) and general weighted negative cumulative extropy (GWNCJ). We obtain its simple estimators for complete and right censored data. We obtain some results on GWCREJ and GWNCJ. We establish its connection to reliability theory and coherent systems. We also propose empirical estimators of weighted negative cumulative extropy (WNCJ).
