description: Two relativistic X-ray jets have been detected with the Chandra X-ray observatory in the black hole X-ray transient XTE J1550-564. We report a full analysis of the evolution of the two jets with a gamma-ray burst external shock model. A plausible scenario suggests a cavity outside the central source and the jets first travelled with constant velocity and then are slowed down by the interactions between the jets and the interstellar medium (ISM). The best fitted radius of the cavity is ~0.36 pc on the eastern side and ~0.46 pc on the western side, and the densities also show asymmetry, of ~0.015 cm$^{-3}$ on the east to ~0.21 cm$^{-3}$ on the west. Large scale low density region is also found in another microquasar system, H 1743-322. These results are consistent with previous suggestions that the environment of microquasars should be rather vacuous, compared to the normal Galactic environment. A generic scenario for microquasar jets is proposed, classifying the observed jets into three main categories, with different jet morphologies (and sizes) corresponding to different scales of vacuous environments surrounding them.

description: The karst area in Yunnan-Guangxi-Guizhou region in southwest China is known for widespread rocky desertification but several studies report a greening trend since the year 2000. While the start of the greening trend seems to match with the implementation of ecological conservation projects, no statistical evidence on a relationship between vegetation greening and eco-engineering exists. Moreover, dominant factors influencing the spatial patterns of vegetation trends have rarely been investigated. Here we use six comprehensive factors representing the natural conditions and human activities of the study area, and several statistical models consistently show that eco-engineering explains large parts of the positive vegetation trends in the karst areas, while negative vegetation trends in non-karst areas of Yunnan were related with a decrease in rainfall. We further show that the interaction of eco-engineering with other factors leads to a heterogeneous pattern of different vegetation trends. Knowing and understanding these patterns is crucial when planning ecological restoration, especially in diverse landscapes like China karst and the methods can be reused in other restoration areas.
title: Towards a Contemporary Venice Biennale: Reassessing the Impact of the 1993 Exhibition
Creators: name: Ricci, Clarissa
Publisher: name: OBOE JOURNAL
Year: 2020

description: This paper argues that Cardinal Points of Art, directed by Achille Bonito Oliva has been decisive in the formation of the contemporary Venice Biennale. The 45th Venice Biennale, (1993) was memorable for many reasons: the first exhibition of Chinese painters in Venice, its transnational approach, and because it was the last time the Aperto exhibition was shown. Nevertheless, this was a complex and much criticised Biennale whose specific characteristics are also connected to the process of reform that the institution had been undergoing since the 1970s. The analysis of the exhibition starts with the examination of this legacy and continues by questioning Bonito Oliva’s curatorial contribution in order to define the specific features which helped to shape the contemporary Venice Biennale.

description: We discuss observing strategy for the Near Infrared Coronagraphic Imager (NICI) on the 8-m Gemini South telescope. NICI combines a number of techniques to attenuate starlight and suppress superspeckles: 1) coronagraphic imaging, 2) dual channel imaging for Spectral Differential Imaging (SDI) and 3) operation in a fixed Cassegrain rotator mode for Angular Differential Imaging (ADI). NICI will be used both in service mode and for a dedicated 50 night planet search campaign. While all of these techniques have been used individually in large planet-finding surveys, this is the first time ADI and SDI will be used with a coronagraph in a large survey. Thus, novel observing strategies are necessary to conduct a viable planet search campaign.

description: The propagation of azimuthally symmetric guided waves in multiwalled carbon nanotubes (MWCNTs) was analyzed theoretically in the mid-infrared and the visible regimes. The MWCNTs were modeled as ensembles of concentric, cylindrical, conducting shells. Slightly attenuated guided waves and antenna resonances due to the edge effect exist for not-too-thick MWCNTs in the far- and mid-infrared regimes. Interband transitions hinder the propagation of guided waves and have a deleterious effect on the performance of a finite-length MWCNT as an antenna. Propagation of surface-plasmon waves along an MWCNT with a gold core was also analyzed. In the near-infrared and the visible regimes, the shells behave effectively as lossy dielectrics suppressing surface-plasmon-wave propagation along the gold core.

Characterization of a subtidal gastropod assemblage in the Strait of Georgia
Creators: name: Cabot, Eric L.
Publisher: name: University of British Columbia
Year: 2010

description: A subtidal site at Saturnina Island was sampled quantitatively to determine the seasonal and depth related trends of gastropod populations. The resulting density estimates were used to characterize the assemblage using diversity, niche-breadth, and cluster analyses. The relationship between gastropod abundance and diatom density, as estimated from colonization of glass microscope slides, was investigated One experiment, which was conducted at the site, was designed to determine whether the macrophytic algae still attracted the numerically dominant snail after the algae had been either cleaned with hydrogen peroxide, or killed by immersion in 50° C. seawater. Most species attained their maximum development after recruitment in spring or early summer. The greatest number of species was found at the shallowest station that was sampled, and abundances tended to decrease with depth with most species. Most of the snails had dispersion patterns that were similar to those of the two dominant species Marqarites costalis and Lacuna marmorata. Ninety-five percent of all the individuals collected were found to belong to five species. This high degree of numerical dominance severely affected the results of the diversity and the cluster analyses. Analyses of frequency vs. mean abundance, and niche-breadths revealed detailed information concerning the distributions of the gastropods that was not readily obtainable from graphs of mean density per quadrat. Diversity, species richness, the total abundance of gastropods, and the densities of several species were correlated to the abundance of diatoms. Several species were also found to contain diatoms among their gut contents. Several other factors, including parasitism, predation, low salinity-high temperature water, and competition are discussed as factors, which, in addition to diatom abundance, may have affected the gastropod dispersion patterns.

description: Geons, small topological structures that exhibit particle properties such as charge and angular momentum without the presence of matter sources, have been extensively discussed in 3+1-dimensional general relativity. Given the recent renewal of interest in 2+1 gravity, it is natural to ask whether or not the notion of geons extends to three dimensions. We prove here that, in contrast to the 3+1-dimensional case, there are no 2+1-dimensional asymptotically flat solutions of the vacuum Einstein or Einstein-Maxwell equations containing geons. In contrast, 2+1-dimensional asymptotically anti-de Sitter spacetimes can indeed contain geons; however, the geons are always hidden behind a single black hole horizon. We also prove sufficient conditions for the non-existence of 2+1-dimensional asymptotically flat geon-containing solutions.

description: We re-analyze the problem of thermally activated phase slips (TAPS) which can dominate the behavior of sufficiently thin superconducting wires at temperatures close to $T_C$. With the aid of an effective action approach we evaluate the TAPS rate which turns out to exceed the rate found by D.E. McCumber and B.I. Halperin, Phys. Rev. B {\bf 1}, 1054 (1970) within the TDGL analysis by the factor $\sim (1-T/T_C)^{-1} \gg 1$. Additional differences in the results of these two approaches arise at bias currents close to the Ginzburg-Landau critical current where the TAPS rate becomes bigger. We also derive a simple formula for the voltage noise across the superconducting wire in terms of the TAPS rate. Our results can be verified in modern experiments with superconducting nanowires.

description: The goal of the College Counsellor Application is to address the rising issues with mental health that young people are facing, especially as they move from high school to college. The app offers individualized mental health support, counselling, and access to a carefully curated collection of mental health materials. It is developed cross-platform using Flutter. The present state of mobile counselling apps, the benefits of communication, and Flutter's role in providing a scalable solution to student mental health issues are all covered in this review. Adolescents frequently deal with serious psychological and personal issues, such as stress, anxiety, and depression, which are made worse by social dynamics and academic demands. Because of factors including high counsellor-to-student ratios, geographic limitations, and the stigma attached to requesting help, traditional counselling services are frequently insufficient. This software seeks to close the gap in mental health services by providing consistent, dependable help that is available whenever and wherever, supporting young people's academic achievement and general well-being. This app aims to bridge the gap in mental health services, offering continuous and reliable support accessible anytime and anywhere, thereby promoting the overall well-being and academic success of young people.

description: Objectives: To examine baseline frailty and its association with rehospitalisation and mortality within 12 months among older adults enrolled in the Western Sydney Clinical Frailty Registry. Design: Prospective observational cohort study. Setting and participants: 592 adults admitted to an acute geriatric medicine service in NSW, Australia, were included in this study. Methods: The Western Sydney Clinical Frailty Registry is a study of adults admitted to acute geriatric wards in a 570-bed two-site district general hospital in Western Sydney, NSW, Australia. Recruitment began in April 2020 and is ongoing. Each participant is recruited while an inpatient and followed up for 12 months, including baseline visits and three-, six- and 12-month follow-ups via telephone interviews. The primary outcome of this study was rehospitalisation and/or mortality at 12 months. Results: Median age 82 years; half the cohort were classified as mild-moderately frail, and 21% were classified as severely frail. A total of 134 participants died (22.6%) within the 12-month follow-up period. Increased cumulative incidence of first rehospitalisation and/or death during the first 12 months post-discharge was significantly associated with higher modified Charlson comorbidity (p < 0.001) and Clinical Frailty Scale (CFS) scores (p < 0.001). Compared to the ‘non-frail’ group (CFS 1–4), those who were severely frail (CFS 7–9) had an 85% increased risk of rehospitalisation and/or death (95% CI 1.36–2.52), and those who were mild-moderately frail (CFS 5–6) had a 52% increased risk after adjusting for effects of the other variables (95% CI 1.18–1.94). Conclusions: Frailty is very common in older adults admitted to acute geriatric services. Assessing frailty using the CFS is feasible and is independently predictive of rehospitalisation and mortality. Our findings suggest that integrating frailty assessment into clinical practice goes beyond simple risk stratification, offering valuable insights for tailored clinical management strategies.

description: Using a field-theoretic approach, we systematically generalize the usual semiclassical approximation for a harmonically trapped ideal Bose gas in such a way that its range of applicability is essentially extended. With this we can analytically calculate thermodynamic properties even for small particle numbers. In particular, it now becomes possible to determine the critical temperature as well as the temperature dependence of both heat capacity and condensate fraction in low-dimensional traps, where the standard semiclassical approximation is not even applicable.

Focusing on the U<0 case, we present in some detail the single-fermion, pair, density and spin spectra, and discuss how spin-charge separation is altered for this system. The pair spectra show a quasi-condensate at a nonzero momentum proportional to the polarization, as expected for this Fulde-Ferrel-Larkin-Ovchinnikov-like superfluid.

While meaning many different things to many different people, the term smart grid has become a common part of our vocabulary, referring to the convergence of communication and power system technologies, particularly in the presence of widespread distributed energy resources. However, the smart grid is only the first step in modernizing our electrical infrastructure - once we have communications and distributed capabilities, we need a means to engage and control diverse utility-owned and third-party assets in a sustainable and reliable manner.

description: We collect 133 Fast Radio Bursts (FRBs), including 110 non-repeating and 23 repeating ones, and systematically investigate their observational properties. To check the frequency dependence of FRB classifications, we define our samples with a central frequency below/above 1GHz as subsample I/II. We find that there is a clear bimodal distribution of pulse width for the subsample I. And If we classify FRBs into short FRBs (\emph{s}FRBs) ($$100 ms) as done for short and long Gamma-Ray Bursts (GRBs), the \emph{s}FRBs at higher central frequency are commonly shorter than those at lower central frequency not only for non-repeating but also repeating \emph{s}FRBs. Secondly, we find that fluence and peak flux density are correlated with a power law relation of $F \varpropto S{^γ_{p,obs}}$ for both \emph{s}FRBs and \emph{l}FRBs whose distributions are obviously different. Thirdly, the \emph{l}FRBs with isotropic energies ranging from $10^{42}$ to $10^{44}$ erg are more energetic than the \emph{s}FRBs in the $F- DM_{EX}$ plane, indicating that they are two representative types. Finally, it is interestingly note that the peak flux density behaves an independence on the redshift when the distance of the FRBs becomes far enough, which is similar to the scenario of peak flux evolving with redshift in the field of GRBs. We predict that fainter FRBs at higher redshift of $z>2$ can be successfully detected by FAST and SKA in the near future.

description: We have measured the critical phase change conditions induced by electrical pulses in Ge2Sb2Te5 nanopillar phase change memory devices by constructing a comprehensive resistance map as a function of pulse parameters (width, amplitude and trailing edge). Our measurements reveal that the heating scheme and the details of the contact geometry play the dominant role in determining the final phase composition of the device such that a non-uniform heating scheme promotes partial amorphization/crystallization for a wide range of pulse parameters enabling multiple resistance levels for data storage applications. Furthermore we find that fluctuations in the snap-back voltage and set/reset resistances in repeated switching experiments are related to the details of the current distribution such that a uniform current injection geometry (i.e. circular contact) favors more reproducible switching parameters. This shows that possible geometrical defects in nanoscale phase change memory devices may play an essential role in the performance of the smallest possible devices through modification of the exact current distribution in the active chalcogenide layer. We present a three-dimensional finite element model of the electro-thermal physics to provide insights into the underlying physical mechanisms of the switching dynamics as well as to quantitatively account for the scaling behaviour of the switching currents in both circular and rectangular contact geometries. The calculated temporal evolution of the heat distribution within the pulse duration shows distinct features in rectangular contacts providing evidence for locally hot spots at the sharp corners of the current injection site due to current crowding effects leading to the observed behaviour.

Volume 15: Issue 4: Microgrid Controllers: The Heart and Soul of Microgrid Automation
Our microgrid controllers issue discusses several applications. The controllers must flexibly provide service to critical loads under a wide variety of operating conditions, including power transfers to and from the interconnecting utility and self-sufficient operation in isolated mode.  Fault detection and isolation schemes must have the ability to function under a wide range of short circuit availability and power flow conditions. The state of the microgrid can be highly variable as a result of configuration changes from forced and maintenance outage conditions, different levels and rate of change of demand, and many output states of supply resources that often include photovoltaics. The physical operation of the microgrid must also respect its business model by minimizing the cost of operation.

description: O presente artigo objetiva apresentar três situações entrelaçadas na formação da realidade econômica, política e religiosa do Ceará: catolicismo, realidade cearense e o episcopado do período. Marcada em sua contextura histórica pelo ultramontanismo, a arquidiocese de Fortaleza é herdeira do bispado do Ceará, fundado no período imperial, portanto, dentro do regime de padroado. Também é fortemente marcada por aspectos geográficos, como o fenômeno da seca. A seca não é um fenômeno simplesmente climático, mas também cultural, político e social, sendo, por vezes, incapaz de ser dissociado do éthos do cearense. Para compreender o processo histórico de desenvolvimento desta arquidiocese, faz-se necessário também apresentar os bispos que estiveram à frente da mesma, até o período do episcopado de Dom José de Medeiros de Delgado.

Micro and Macro essays in Applied Fiscal Policy

description: This thesis analysis micro and macro aspect of applied fiscal policy issues. The first chapter investigates the extent to which local budget spending composition reacts to fiscal rules variations. I consider the budget of Italian
municipalities and exploit specific changes in the Domestic Stability Pact’s rules, to perform a difference-in-discontinuities analysis. The results show that imposing a cap on the total amount of consumption and investment is not as binding as two caps, one for consumption and a different one for investment. More specifically,  consumption is triggered by changes in wages and services spending, while investment relies on infrastructure movements. In addition, there is evidence that when an increase in investment is achieved, there is also a higher budget deficit level.
The second chapter intends to analyze the extent to which fiscal policy shocks are able to affect macrovariables during business cycle fluctuations, differentiating among
three intervention channels: public taxation, consumption and investment. The econometric methodology implemented is a Panel Vector Autoregressive model with a structural characterization. The results show that fiscal shocks
have different multipliers in relation to expansion or contraction periods: output does not react during good times while there are significant effects in bad ones.
The third chapter evaluates the effects of fiscal policy announcements by the Italian government on the long-term sovereign bond spread of Italy relative to Germany. After collecting data on relevant fiscal policy announcements, we perform an econometric comparative analysis between the three cabinets that followed one another during the period 2009-2013. The results suggest that only fiscal policy announcements made by members of Monti’s cabinet have been effective in influencing significantly the Italian spread in the expected direction, revealing a remarkable credibility gap between Berlusconi’s and Letta’s governments with respect to Monti’s administration.

description: We propose a class of locally and asymptotically optimal tests, based on multivariate ranks and signs for the homogeneity of scatter matrices in $m$ elliptical populations. Contrary to the existing parametric procedures, these tests remain valid without any moment assumptions, and thus are perfectly robust against heavy-tailed distributions (validity robustness). Nevertheless, they reach semiparametric efficiency bounds at correctly specified elliptical densities and maintain high powers under all (efficiency robustness). In particular, their normal-score version outperforms traditional Gaussian likelihood ratio tests and their pseudo-Gaussian robustifications under a very broad range of non-Gaussian densities including, for instance, all multivariate Student and power-exponential distributions.

description: Precision Agriculture (PA) and the more specific branch of Precision Horticulture are two very promising sectors. They  focus on the use of technologies in agriculture to optimize the use of inputs, so to reach a better efficiency, and minimize waste of resources.
This important objective motivated many researchers and companies to search new technology solutions. Sometimes the effort proved to be a good seed, but sometimes an unfeasible idea. So that PA, from its birth more or less 25 years ago, is still a “new” management, interesting for the future, but an actual low adoption rate is still reported by experts and researchers.
This work aims to give a contribution in finding the causes of this low adoption rate and proposing a methodological solution to this problem.
The first step was to examine prior research about Precision Agriculture adoption, by ex ante and ex post approach. It was supposed as important to find connections between these two phases of a purchase experience. In fact, the ex ante studies dealt with potential consumer’s perceptions before a usage experience occurred, therefore before purchasing a technology, while the ex post studies described the drivers which made a farmer become an end-user of PA technology.
Then, an example of consumer research is presented. This was an ex ante research focused on pre-prototype technology for fruit production. This kind of research could give precious information about consumer acceptance before reaching an advanced development phase of the technology, and so to have the possibility to change something with the least financial impact.
The final step was to develop the pre-prototype technology that was the subject of the consumer acceptance research and test its technical characteristics.

description: A/B tests have been widely adopted across industries as the golden rule that guides decision making. However, the long-term true north metrics we ultimately want to drive through A/B test may take a long time to mature. In these situations, a surrogate metric which predicts the long-term metric is often used instead to conclude whether the treatment is effective. However, because the surrogate rarely predicts the true north perfectly, a regular A/B test based on surrogate metrics tends to have high false positive rate and the treatment variant deemed favorable from the test may not be the winning one. In this paper, we discuss how to adjust the A/B testing comparison to ensure experiment results are trustworthy. We also provide practical guidelines on the choice of good surrogate metrics. To provide a concrete example of how to leverage surrogate metrics for fast decision making, we present a case study on developing and evaluating the predicted confirmed hire surrogate metric in LinkedIn job marketplace.

description: Abstract: Integration of artificial intelligence (AI) into the marketing of social media has transformed the way the brands work with consumers, relationships and support loyalty. This document examines the impact of the Sentiment of Sentiment supported by AM on the involvement of consumers and a brand loyalty with a special focus on the retail industry. The AI sentiment analysis tools monitor and interpret customer emotions, provide real -time knowledge that help brands to adapt their message, improve customer experience and predict loyalty trends. This study, which uses access with mixed methods, uses both qualitative and quantitative data, including surveys, interviews and reviews of literature, to assess how AI technology affects consumers' behavior. Research identifies key metrics of consumers, such as the degree of clickthrough, customer satisfaction and the frequency of social media interaction, exploring their relationship with marketing strategies on AI. In addition, it emphasizes the importance of real time feedback in improving brand loyalty and maintaining customers. Finding out of the study reveals that analysis of AI sentiment increases marketing efficiency by allowing hyper personalized content, immediately addressing customers' concerns and improving the overall perception of the brand. This not only drives deeper engagement, but also strengthens the long -term loyalty of the brand. The contribution also discusses the practical consequences of receiving AI -controlled tools and provides retailers that seek to optimize the location of the brand on the competitive digital market, recommendations that can be optimized. Overall, research emphasizes that the AF sentiment analysis plays a decisive role in the formation of relationships with the consumer brand and offers insight into future trends and applications in AI -based digital marketing.

description: We present, solve and numerically simulate a simple model that describes the consequences of increased longevity on fertility rates, population growth and the distribution of wealth in developed societies. We look at the consequences of the repeated use of life extension techniques and show that they represent a novel commodity whose introduction will profoundly influence key aspects of economy and society in general. In particular, we uncover two phases within our simplified model, labeled as 'mortal' and 'immortal'. Within the life extension scenario it is possible to have sustainable economic growth in a population of stable size, as a result of dynamical equilibrium between the two phases.
