description: This paper addresses the problem of corpus-level entity typing, i.e., inferring from a large corpus that an entity is a member of a class such as "food" or "artist". The application of entity typing we are interested in is knowledge base completion, specifically, to learn which classes an entity is a member of. We propose FIGMENT to tackle this problem. FIGMENT is embedding- based and combines (i) a global model that scores based on aggregated contextual information of an entity and (ii) a context model that first scores the individual occurrences of an entity and then aggregates the scores. Each of the two proposed models has some specific properties. For the global model, learning high quality entity representations is crucial because it is the only source used for the predictions. Therefore, we introduce representations using name and contexts of entities on the three levels of entity, word, and character. We show each has complementary information and a multi-level representation is the best. For the context model, we need to use distant supervision since the context-level labels are not available for entities. Distant supervised labels are noisy and this harms the performance of models. Therefore, we introduce and apply new algorithms for noise mitigation using multi-instance learning. We show the effectiveness of our models in a large entity typing dataset, built from Freebase.

description: Recently, Artificial Intelligence (AI)-based algorithms have revolutionized the medical image segmentation processes. Thus, the precise segmentation of organs and their lesions may contribute to an efficient diagnostics process and a more effective selection of targeted therapies as well as increasing the effectiveness of the training process. In this context, AI may contribute to the automatization of the image scan segmentation process and increase the quality of the resulting 3D objects, which may lead to the generation of more realistic virtual objects. In this paper, we focus on the AI-based solutions applied in the medical image scan segmentation, and intelligent visual-content generation, i.e. computer-generated three-dimensional (3D) images in the context of Extended Reality (XR). We consider different types of neural networks used with a special emphasis on the learning rules applied, taking into account algorithm accuracy and performance, as well as open data availability. This paper attempts to summarize the current development of AI-based segmentation methods in medical imaging and intelligent visual content generation that are applied in XR. It concludes also with possible developments and open challenges in AI application in Extended Reality-based solutions. Finally, the future lines of research and development directions of Artificial Intelligence applications both in medical image segmentation and Extended Reality-based medical solutions are discussed

description: Constata-se como objetivo geral do trabalho a análise da justiça em adotar medidas preventivas e punitivas contra a ocorrência de assédio sexual na indústria de entretenimento brasileira. São objetivos específicos: investigar as circunstâncias de ocorrências de assédio sexual na indústria de entretenimento brasileira; verificar a forma de denúncia das mulheres assediadas; reconhecer as consequências desenvolvidas pelas vítimas; examinar a reinserção no mercado de trabalho das vítimas assediadas. Quando se analisa o passado da mulher na história nota-se a grande luta que tiveram em busca de seus direitos. Com o passar dos anos, cada vez mais a mulher conquistava funções que eram historicamente masculinas ganhando espaço no mercado de trabalho. A oposição sofrida contra o ingresso das mulheres no mercado de trabalho é de que ainda há uma rotulação dessas como sendo inabilitadas e incapazes de realizar cargos profissionalizantes. A partir disso, a mulher ainda continua sendo vista como objeto de satisfação do homem sendo esse o ponto determinante para o assédio sexual contra elas, principalmente no ambiente de trabalho. Segundo Mary Cardone se traduz o assédio sexual pela atitude de alguém que, desejado obter favores libidinosos de outra pessoa, causa a esta constrangimento, por não haver reciprocidade (CARDONE, 1994, p.393).

description: Third-party dependency updates can cause a build to fail if the new dependency version introduces a change that is incompatible with the usage: this is called a breaking dependency update. Research on breaking dependency updates is active, with works on characterization, understanding, automatic repair of breaking updates, and other software engineering aspects. All such research projects require a benchmark of breaking updates that has the following properties: 1) it contains real-world breaking updates; 2) the breaking updates can be executed; 3) the benchmark provides stable scientific artifacts of breaking updates over time, a property we call reproducibility. To the best of our knowledge, such a benchmark is missing. To address this problem, we present BUMP, a new benchmark that contains reproducible breaking dependency updates in the context of Java projects built with the Maven build system. BUMP contains 571 breaking dependency updates collected from 153 Java projects. BUMP ensures long-term reproducibility of dependency updates on different platforms, guaranteeing consistent build failures. We categorize the different causes of build breakage in BUMP, providing novel insights for future work on breaking update engineering. To our knowledge, BUMP is the first of its kind, providing hundreds of real-world breaking updates that have all been made reproducible.

description: A semi-relativistic potential model is adopted to calculate the mass spectra of charmed and charmed-strange meson states up to the $2D$ excitations.The strong decay properties are further analyzed with a chiral quark model by using the numerical wave functions obtained from the potential model. By using the strong decay amplitudes extracted from the chiral quark model, we also systematically study the coupled-channel effects on the bare masses of the $1P$-wave states, since the masses of $D^*_{s0}(2317)$ and $D_{s1}(2460)$ cannot be explained with bare $1P$-wave states within the potential model. Based on our good descriptions of the mass and decay properties for the low-lying well-established states, we give a quark model classification for the high mass resonances observed in recent years. In the $D$-meson family, $D_0(2550)$ can be classified as the radially excited state $D(2^1S_0)$; $D_3^*(2750)$ and $D_2(2740)$ can be classified as the second orbital excitations $D(1^3D_3)$ and $D(1D'_2)$, respectively; $D_J^*(3000)$ may be a candidate of $D(1^3F_4)$ or $D(2^3P_2)$; while $D_J(3000)$ may favor the high mass mixed state $D(2P'_1)$; however, there still exist puzzles for understanding the natures of $D_1^*(2600)$ and $D_1^*(2760)$, whose decay properties cannot be well explained with either pure $D(2^3S_1)$ and $D(1^3D_1)$ states or their mixing. In the $D_s$-meson family, $D_{s3}^*(2860)$ favors the $D_s(1^3D_3)$ assignment; $D_{s1}^*(2700)$ and $D_{s1}^*(2860)$ may favor the mixed states $|(SD)_1\rangle_L$ and $|(SD)_1\rangle_H$ via the $2^3S_1$-$1^3D_1$ mixing, respectively; $D_{sJ}(3040)$ may favor $D_s(2P_1)$ or $D_s(2P_1')$, or corresponds to a structure contributed by both $D_s(2P_1)$ and $D_s(2P_1')$.

We construct stationary inhomogeneous black hole solutions in which both the U(1) symmetry and spatially translational symmetry are spontaneously broken at finite temperature and charge density. This novel solution provides a dual description of a superconducting phase intertwined with charge, current and parity orders.

description: The Large Magellanic Cloud (LMC) is the Milky Way's most massive satellite galaxy, which only recently (~2 billion years ago) fell into our Galaxy. Since stellar atmospheres preserve their natal cloud's composition, the LMC's recent infall makes its most ancient, metal-deficient ("low-metallicity") stars unique windows into early star formation and nucleosynthesis in a formerly distant region of the high-redshift universe. Previously, identifying such stars in the LMC was challenging. But new techniques have opened this window, now enabling tests of whether the earliest element enrichment and star formation in distant, extragalactic proto-galaxies deviated from what occurred in the proto-Milky Way. Here we present the elemental abundances of 10 stars in the LMC with iron-to-hydrogen ratios ranging from ~1/300th to ~1/12,000th of the Sun. Our most metal-deficient star is 50 times more metal-deficient than any in the LMC with available detailed chemical abundance patterns, and is likely enriched by a single extragalactic first star supernova. This star lacks significant carbon-enhancement, as does our overall sample, in contrast with the lowest metallicity Milky Way stars. This, and other abundance differences, affirm that the extragalactic early LMC experienced diverging enrichment processes compared to the early Milky Way. Early element production, driven by the earliest stars, thus appears to proceed in an environment-dependent manner.

description: O Direito dos animais no Brasil é pouco regulado e menos ainda fiscalizado. Como exemplo da ineficácia das leis ambientais, encontramos a venda de animais no Mercado Central de Belo Horizonte. A crueldade com os animais, o prejuízo infringido aos comerciantes e aos consumidores são as principais razões para que essa prática seja interrompida. O objetivo geral do trabalho é analisar a infração da Constituição e do Código Civil brasileiro pela prática de comercialização de animais vivos no Mercado Central de Belo Horizonte. Como objetivos específicos do trabalho, enumeram-se os seguintes: a) analisar as condições de higiene em que os animais são mantidos; b) verificar a eficácia das leis acerca dos Direitos dos Animais; c) comparar a prática do Mercado Central de Belo Horizonte a mercados de outras cidades; e) averiguar o parecer de veterinários acerca da saúde e qualidade de vida dos animais comercializados nestas condições; f) levantar dados de quantos de animais são mortos desde o transporte ate o momento da venda; g) averiguar a fiscalização dos órgãos públicos; apurar a quais tipos maus-tratos e sofrimento estes animais são submetidos. Segundo José Carlos, [...] o Código Civil trata o animal como objeto, sem prever qualquer regra relativa ao seu bem-estar, optando pela fórmula genérica de previsão de preservação (“de modo que sejam preservados”) nos termos de outras leis (JÚNIOR, 2015, p.139). Em suma, o Código Civil pouco regulamenta sobre o direito dos animais, possibilitando brechas para comerciantes que aderem práticas semelhantes a do Mercado Central de Belo Horizonte.

description: The growing literature on affect among software developers mostly reports on the linkage between happiness, software quality, and developer productivity. Understanding happiness and unhappiness in all its components -- positive and negative emotions and moods -- is an attractive and important endeavor. Scholars in industrial and organizational psychology have suggested that understanding happiness and unhappiness could lead to cost-effective ways of enhancing working conditions, job performance, and to limiting the occurrence of psychological disorders. Our comprehension of the consequences of (un)happiness among developers is still too shallow, being mainly expressed in terms of development productivity and software quality. In this paper, we study what happens when developers are happy and unhappy while developing software. Qualitative data analysis of responses given by 317 questionnaire participants identified 42 consequences of unhappiness and 32 of happiness. We found consequences of happiness and unhappiness that are beneficial and detrimental for developers' mental well-being, the software development process, and the produced artifacts. Our classification scheme, available as open data enables new happiness research opportunities of cause-effect type, and it can act as a guideline for practitioners for identifying damaging effects of unhappiness and for fostering happiness on the job.

description: Although there has been significant advancement in the field of speech-to-speech translation, conventional models still require language-parallel speech data between the source and target languages for training. In this paper, we introduce TranSentence, a novel speech-to-speech translation without language-parallel speech data. To achieve this, we first adopt a language-agnostic sentence-level speech encoding that captures the semantic information of speech, irrespective of language. We then train our model to generate speech based on the encoded embedding obtained from a language-agnostic sentence-level speech encoder that is pre-trained with various languages. With this method, despite training exclusively on the target language's monolingual data, we can generate target language speech in the inference stage using language-agnostic speech embedding from the source language speech. Furthermore, we extend TranSentence to multilingual speech-to-speech translation. The experimental results demonstrate that TranSentence is superior to other models.

Non-linear density-velocity dynamics in $f(R)$ gravity from spherical collapse

description: We investigate the joint density-velocity evolution in $f(R)$ gravity using smooth, compensated spherical top-hats as a proxy for the non-linear regime. Using the Hu-Sawicki model as a working example, we solve the coupled continuity, Euler and Einstein equations using an iterative hybrid Lagrangian-Eulerian scheme. The novel aspect of this scheme is that the metric potentials are solved for analytically in the Eulerian frame. The evolution is assumed to follow GR at very early epochs and switches to $f(R)$ at a pre-determined epoch. Choosing the `switching epoch' too early is computationally expensive because of high frequency oscillations; choosing it too late potentially destroys consistency with $Λ$CDM. To make an informed choice, we perform an eigenvalue analysis of the background model which gives a ballpark estimate of the magnitude of oscillations. There are two length scales in the problem: the comoving Compton wavelength of the associated scalar field and the width of the top-hat. The evolution is determined by their ratio. When the ratio is large, the evolution is scale-independent and the density-velocity divergence relation (DVDR) is unique. When the ratio is small, the evolution is very close to GR, except for the formation of a spike near the top-hat edge, a feature which has been noted in earlier literature. We are able to qualitatively explain this feature in terms of the analytic solution for the metric potentials, in the absence of the chameleon mechanism. In the intermediate regime, the evolution is profile-dependent and no unique DVDR exists.

description: Anharmonicity strongly influences the absorption and emission spectra of polycyclic aromatic hydrocarbon (PAH) molecules. Here, IR-UV ion-dip spectroscopy experiments together with detailed anharmonic computations reveal the presence of fundamental, overtone, as well as 2- and 3-quanta combination band transitions in the far- and mid-infrared absorption spectrum of phenylacetylene and its singly deuterated isotopologue. Strong absorption features in the 400-900 cm$^{\rm -1}$ range originate from CH(D) in-plane and out-of-plane wags and bends, as well as bending motions including the C$\equiv$C and CH bonds of the acetylene substituent and the aromatic ring. For phenylacetylene, every absorption feature is assigned either directly or indirectly to a single or multiple vibrational mode(s). The measured spectrum is dense, broad, and structureless in many regions but well characterized by computations. Upon deuteration, large isotopic shifts are observed. At frequencies above 1500 cm$^{\rm -1}$ for d$_1$-phenylacetylene, a one-to-one match is seen when comparing computations and experiment with all features assigned to combination bands and overtones. The C$\equiv$C stretch observed in phenylacetylene is not observed in d$_1$-phenylacetylene due to a computed 40-fold drop in intensity. Overall, a careful treatment of anharmonicity that includes 2- and 3-quanta modes is found to be crucial to understand the rich details of the infrared spectrum of phenylacetylene. Based on these results, it can be expected that such an all-inclusive anharmonic treatment will also be key for unraveling the infrared spectra of PAHs in general.

Inverse and direct energy cascades in 3D MHD turbulence at low-Rm

description: This experimental study analyzes the relationship between the dimensionality of turbulence and the upscale or downscale nature of its energy transfers. We do so by forcing low-$Rm$ magnetohydrodynamic (MHD) turbulence in a confined channel, while precisely controlling its dimensionality by means of an externally applied magnetic field. We first identify a specific lengthscale $\hat{l}_\perp^c$ that separates smaller three-dimensional structures from larger quasi-two-dimensional ones. We then show that an inverse energy cascade of horizontal kinetic energy along horizontal scales is always observable at large scales, but that it extends well into the region of 3D structures. At the same time, a direct energy cascade confined to the smallest and strongly 3D scales is observed. These dynamics therefore appear not to be simply determined by the dimensionality of individual scales, nor by the forcing scale, unlike in other studies. In fact, our findings suggest that the relationship between kinematics and dynamics is not universal and may strongly depend on the forcing and dissipating mechanisms at play.

description: Constata-se como objetivo geral do trabalho analisar como o feminismo alcança as mulheres indígenas e afeta as aldeias como um todo, além disso, irá ser verificado como essa luta se relaciona com as questões culturais desse grupo e com as leis brasileiras que visam garantir o direito das mulheres. São objetivos específicos: a) Analisar o que a mulher representa para os povos indígenas; b) Investigar qual a opinião das mulheres indígenas sobre sua situação; c) Avaliar de que forma a lei brasileira intervém na cultura indígena; d) Verificar se os direitos das mulheres indígenas estão sendo garantidos; e) Comparar o movimento feminista indígena brasileiro com o mesmo movimento em outros países; f) Investigar como os homens indígenas julgam o feminismo indígena; g) Investigar as diferentes visões acerca do tema a partir da perspectiva de diferentes gerações de mulheres. O movimento feminino indígena, é recente e que vem conquistando espaço ao longo dos anos, através de órgãos e associações engajadas na causa (VERDUM, 2008). Esse debate se revela essencial por proporcionar visibilidade para mulheres que estão inseridas em um grupo que, de maneira geral, é bastante inferiorizado pela sociedade. As indígenas, além de encararem as questões interétnicas – relações entre a cultura indígena e a cultura “brasileira” – precisam lidar com as relações existentes em sua própria comunidade. Essas mulheres não lutam apenas para serem reconhecidas pela sociedade brasileira, mas também para serem respeitadas em suas aldeias. Dessa forma, discutir gênero nesse contexto é complicado, pois questionar a ordem vigente e propor mudanças pode significar a desestruturação de uma sociedade por completo (CASTILHO, 2008, p.23-24). Essas dificuldades apenas evidenciam a necessidade de um debate sobre o assunto.

description: In this letter, we present the results from further X-ray and UV observations of the nuclear transient eRASSt J045650.3-203750 (hereafter J0456-20). We detected five repeating X-ray and UV flares from J0456-20, making it one of the most promising repeating partial tidal disruption event (pTDE) candidates. More importantly, we also found rapid changes in the recurrence time $T_\text{recur}$ of the X-ray flares by modelling the long-term X-ray light curve of J0456-20. $T_\text{recur}$ first decreased rapidly from about 300 days to around 230 days. It continued to decrease to around 190 days with an indication of a constant $T_\text{recur}$ evidenced from the latest three cycles. Our hydrodynamic simulations suggest that, in the repeating pTDE scenario, such rapid evolution of $T_\text{recur}$ could be reproduced if the original star is a $1~\mathrm{M}_\odot$ main-sequence star near the terminal age and loses nearly 80-90% of its mass during the initial encounter with a supermassive black hole (SMBH) of mass around $10^5~\mathrm{M}_\odot$. The inferred mass loss of 0.8-0.9 $\mathrm{M}_\odot$ is higher than the estimated value of around 0.13 $\mathrm{M}_\odot$ from observation, which could be explained if the radiation efficiency is low (i.e. $\ll0.1$). Our results indicate that repeating pTDEs could be effective tools to explore the dynamics around supermassive black holes beyond our own Galaxy.

description: Recently, significant efforts have been made to create Health Digital Twins (HDTs), digital twins for clinical applications. Heart modeling is one of the fastest-growing fields, which favors the effective application of HDTs. The clinical application of HDTs will be increasingly widespread in the future of healthcare services and has a huge potential to form part of the mainstream in medicine. However, it requires the development of both models and algorithms for the analysis of medical data, and advances in Artificial Intelligence (AI) based algorithms have already revolutionized image segmentation processes. Precise segmentation of lesions may contribute to an efficient diagnostics process and a more effective selection of targeted therapy. In this paper, a brief overview of recent achievements in HDT technologies in the field of cardiology, including interventional cardiology was conducted. HDTs were studied taking into account the application of Extended Reality (XR) and AI, as well as data security, technical risks, and ethics-related issues. Special emphasis was put on automatic segmentation issues. It appears that improvements in data processing will focus on automatic segmentation of medical imaging in addition to three-dimensional (3D) pictures to reconstruct the anatomy of the heart and torso that can be displayed in XR-based devices. This will contribute to the development of effective heart diagnostics. The combination of AI, XR, and an HDT-based solution will help to avoid technical errors and serve as a universal methodology in the development of personalized cardiology. Additionally, we describe potential applications, limitations, and further research directions.

description: Among the Renormalization Group Theory scaling rules relating critical exponents, there are hyperscaling rules involving the dimension of the system. It is well known that in Ising models hyperscaling breaks down above the upper critical dimension. It was shown by M. Schwartz [Europhys. Lett. {\bf 15}, 777 (1991)] that the standard Josephson hyperscaling rule can also break down in Ising systems with quenched random interactions. A related Renormalization Group Theory hyperscaling rule links the critical exponents for the normalized Binder cumulant and the correlation length in the thermodynamic limit. An appropriate scaling approach for analyzing measurements from criticality to infinite temperature is first outlined. Numerical data on the scaling of the normalized correlation length and the normalized Binder cumulant are shown for the canonical Ising ferromagnet model in dimension three where hyperscaling holds, for the Ising ferromagnet in dimension five (so above the upper critical dimension) where hyperscaling breaks down, and then for Ising spin glass models in dimension three where the quenched interactions are random. For the Ising spin glasses there is a breakdown of the normalized Binder cumulant hyperscaling relation in the thermodynamic limit regime, with a return to size independent Binder cumulant values in the finite-size scaling regime around the critical region.

description: We study the electronic transport of armchair and zigzag gated phosphorene junctions. We find confined states for both direction-dependent phosphorene junctions. In the case of armchair junctions confined states are reflected in the transmission properties as Fabry-Pérot resonances at normal and oblique incidence. In the case of zigzag junctions confined states are invisible at normal incidence, resulting in a null transmission. At oblique incidence Fabry-Pérot resonances are presented in the transmission as in the case of armchair junctions. This invisibility or electronic cloaking is related to the highly direction-dependent pseudospin texture of the charge carriers in phosphorene. Electronic cloaking is also manifested as a series of singular peaks in the conductance and as inverted peaks in the Seebeck coefficient. The characteristics of electronic cloaking are also susceptible to the modulation of the phosphorene bandgap and an external magnetic field. So, electronic cloaking in phosphorene junctions in principle could be tested through transport, thermoelectric or magnetotransport measurements.

description: O objetivo geral do trabalho é analisar a alteração constitucional proveniente da emenda constitucional nº55/2016, e as possíveis consequências para a saúde e para a educação pública no Brasil. Como objetivos específicos do trabalho, enumeram-se os seguintes: a) analisar a possível inconstitucionalidade da PEC nº55/2016; b) Verificar as consequências sociais para a população brasileira; c) Constatar possíveis consequências de sua aprovação; d) Avaliar possíveis prejuízos à saúde e educação. A emenda constitucional nº55/2016 pretende inserir no Ato das Disposições Constitucionais Transitórias um “Novo Regime Fiscal”, com o intuito de limitar as despesas nas áreas primárias, como saúde e educação. Porém, a saúde e educação são princípios básicos para que uma sociedade possa prosperar, de acordo com Edivaldo Boaventura, o Brasil, em maior parte da sua história, privilegiou investimentos industriais e se atrasou de forma considerável no bem-estar social (BOAVENTURA, 1997)

description: We present a scheme for dissipatively generating maximal entanglement in a heralded manner. Our setup requires incoherent interactions with two thermal baths at different temperatures, but no source of work or control. A pair of $(d+1)$-dimensional quantum systems is first driven to an entangled steady state by the temperature gradient, and maximal entanglement in dimension $d$ can then be heralded via local filters. We discuss experimental prospects considering an implementation in superconducting systems.

Quasi-probabilities of work and heat in an open quantum system

description: We discuss an approach to determine averages of the work, dissipated heat and variation of internal energy of an open quantum system driven by an external classical field. These quantities are measured by coupling the quantum system to a quantum detector at different times. This approach allows us to preserve the full quantum features of the evolution. From the measured phase, we are able to obtain a quasi-characteristic function and a quasi-probability density function for the corresponding observables. Despite the fact that these quasi-probability density functions are not the results of direct measurements, they reproduce the expected value of the physical quantities. Analogously to the Wigner function, the negative regions of these quasi-probability density functions are directly related to pure quantum processes which are not interpretable in classical terms. We use this feature to show that in the limit of strong dissipation, the quantum features vanish and interpret this as the emergence of the classical limit of the energy exchange process. Our analysis explains and confirms the behavior observed in recent experiments performed on IBMQ devices [1]. The possibility to discriminate between classical and quantum features makes the proposed approach an excellent tool to determine if, and in which conditions, quantum effects can be exploited to increase the efficiency in an energy exchange process at the quantum level.

description: Constata-se como objetivo geral do trabalho analisar a maneira como a Prefeitura de Belo Horizonte age a fim de garantir o direito fundamental de moradia a pessoas em situação de rua e, a partir disso, refletir acerca das causas para que as vagas em abrigos e albergues, voltados a esse grupo, não sejam totalmente preenchidas. São objetivos específicos: a) Analisar como a Prefeitura de Belo Horizonte age a fim de garantir o direito fundamental à moradia a todos os moradores da capital mineira; b) Levantar o número de pessoas em vulnerabilidade social no município; c) Investigar como se organizam as instituições voltadas à assistência desse grupo de pessoas; d) Investigar as razões para que haja vagas remanescentes nos abrigos; e) Constatar possíveis soluções para o problema; Embora o direito à moradia seja assegurado pela Constituição Federal brasileira de 1988, no artigo 6, ele nem sempre é garantido a todos os cidadãos (BRASIL, 1988). Isso resulta em um fenômeno em que pessoas não têm acesso à uma moradia fixa e regular, gerando a chamada população em situação de rua. Este cenário é problemático por ser praticamente onipresente nas grandes cidades brasileiras, estando em constante aumento, sobretudo nas capitais. É o que prova o jornal Hoje Em Dia, ao citar a Secretaria de Políticas Sociais de Belo Horizonte, ao dizer que houve um aumento de quase 70% da população em situação de rua da capital mineira entre os anos de 2014 e 2017 (MARIANO, 2017).
Gamma-ray emission from middle-aged supernova remnants interacting with molecular clouds: the challenge for current models

description: We compare the $γ$-ray spectra from 10 middle-aged supernova remnants (SNRs), which are interacting with molecular clouds (MCs), with the model prediction from widely used escaping scenario and direct interaction scenario. It is found that the $γ$-ray data is inconsistent with the escaping scenario statistically, as it predicts a diversity of spectral shape which is not observed. The inconsistency suggests that the free escape boundary adopted in the escaping model is not a good approximation, which challenges our understanding of cosmic ray (CR) escaping in SNRs. In addition, we show that ambient CRs is potentially important for the $γ$-ray emission of illuminated MCs external to W28 and W44. In direct interaction scenario, the model involving re-acceleration of pre-existing CRs and adiabatic compression is able to explain the emission from most SNRs. The dispersion shown in the TeV data is naturally explained by different acceleration time of CR particles in SNRs. Re-acceleration of pre-existing CRs suggests a transition of seed particles, which is from thermal injected seed particle in young SNRs to ambient CRs in old SNRs. The transition needs to be tested by future multi-wavelength observation. In the end, we propose that radiative SNR without MC interaction is also able to produce a significant amount of $γ$-ray emission. A good candidate is S147. With accumulated Fermi data and CTA in future we expect to detect more remnants like S147.

description: The analysis of azimuthal correlations in multiparticle production can be useful to uncover the existence of new physics beyond the Standard Model, e.g., Hidden Valley, in $e^+e^-$ annihilation at high energies. In this paper, based on previous theoretical studies and using PYTHIA8 event generator, it is found that both azimuthal and rapidity long-range correlations are enhanced due to the presence of a new stage of matter on top of the QCD partonic cascade. Ridge structures, similar to those observed at the LHC, show up providing a possible signature of new physics at future $e^+e^-$ colliders.
