description: O presente trabalho busca discutir acerca de procedimentos metodológicos adequados às características e problemas resultantes das reminiscências das práticas musicais na Comunidade Remanescente Quilombo do Carmo localizada no município de São Roque no Estado de São Paulo (Brasil), com base nas políticas públicas com vistas à Memória musical do município. A pesquisa acadêmicamente orientada, através da prática social da escrita, promove o conhecimento, dentro da estabilidade do objeto escrito. No entanto os procedimentos da pesquisa devem considerar ferramentas metodológicas compatíveis à oralidade e à instabilidade que se apresenta nas constantes transformações sociais da comunidade, a fim de contemplar o entendimento de identidades a partir dos agentes delas protagonistas. Dentro deste contexto, empregamos a orientação teórica de autores como Sardo para elucidar os conceitos de Identidade e música; Bosi e Reily no que concerne ao campo das memórias (Coletiva e Individual); Marchuschi em relação à Oralidade e Escrita. A sistematização política a esse Patrimônio Cultural em detrimento da legislação vigente, conduz a problemas sociais de intenso aprofundamento que demandam grande mobilidade de agentes para reavivar as práticas culturais daquela comunidade. Neste sentido, a Pesquisa-ação proposta por Tripp se apresenta como um procedimento metodológico que contempla tanto as demandas teóricas (acadêmicas) como as demandas práticas das vivências do objeto de estudo. Estabelece-se aqui o paralelo entre práticas musicais, memória coletiva e identidade.

description: Using numerical hydrodynamics simulations we studied the gravitational collapse of pre-stellar cores of sub-solar mass embedded into a low-density external environment. Four models with different magnitude and direction of rotation of the external environment with respect to the central core were studied and compared with an isolated model. We found that the infall of matter from the external environment can significantly alter the disk properties as compared to those seen in the isolated model. Depending on the magnitude and direction of rotation of the external environment, a variety of disks can form including compact (<= 200 AU) ones shrinking in size due to infall of external matter with low angular momentum, as well as extended disks forming due to infall of external matter with high angular momentum. The former are usually stable against gravitational fragmentation, while the latter are prone to fragmentation and formation of stellar systems with sub-stellar/very-low-mass companions. In the case of counterrotating external environment, very compact (< 5 AU) and short-lived (<= a few * 10^5 yr) disks can form when infalling material has low angular momentum. The most interesting case is found for the infall of counterrotating external material with high angular momentum, leading to the formation of counterrotating inner and outer disks separated by a deep gap at a few tens AU. The gap migrates inward due to accretion of the inner disk onto the protostar, turns into a central hole, and finally disappears giving way to the outer strongly gravitationally unstable disk. This model may lead to the emergence of a transient stellar system with sub-stellar/very-low-mass components counterrotating with respect to that of the star.

Subjects: subject: Functional Analysis (math.FA)

description: A comprehensive analysis of Sobolev-type inequalities for the Ornstein-Uhlenbeck operator in the Gauss space is offered. A unified approach is proposed, providing one with criteria for their validity in the class of rearrangement-invariant function norms. Optimal target and domain norms in the relevant inequalities are characterized via a reduction principle to one-dimensional inequalities for a Calderón type integral operator patterned on the Gaussian isoperimetric function. Consequently, the best possible norms in a variety of specific families of spaces, including Lebesgue, Lorentz, Lorentz-Zygmund, Orlicz and Marcinkiewicz spaces, are detected. The reduction principle hinges on a preliminary discussion of the existence and uniqueness of generalized solutions to equations, in the Gauss space, for the Ornstein-Uhlenbeck operator, with a just integrable right-hand side. A decisive role is also played by a pointwise estimate, in rearrangement form, for these solutions.

description: We define a quantum witness for high-mass matter-wave interferometers that allows us to test fundamental assumptions of macroscopic realism. We propose an experimental realisation using absorptive laser gratings and show that such systems can strongly violate a macrorealistic quantum-witness equality. The measurement of the witness can therefore provide clear evidence of physics beyond macrorealism for macromolecules and nanoparticles.

“Tocam por qualquer preço”: O estatuto do músico na vila termal de Vidago durante o Estado Novo
Creators: name: Lacerda, Maria Teresa
Publisher: name: Post-ip: Revista do Fórum Internacional de Estudos em Música e Dança
Year: 2020

description: Vidago, uma vila rural de Trás-os-Montes, ganhou visibilidade pelas suas águas termais premiadas (Cruz 1970; Pereira 1971; Salvador 2004). Com o propósito de se tornar um destino turístico privilegiado, passou por um processo de crescimento súbito e introdução de produtos e tecnologias da modernidade. Os estabelecimentos hoteleiros promoviam actividades desportivas e eventos musicais ao vivo para entreter os visitantes durante a temporada de termas (Pereira 2014). Entre a pluralidade de estilos e categorias musicais interpretados incluíam-se arranjos para banda, chanson française, tangos, árias de ópera, fados, jazz, música clássica, rancho folclórico – havendo uma clara preferência por versões de obras com alargada divulgação e popularidade, associadas a transmissões radiofónicas (Moreira, Cidra, e Castelo-Branco 2010). Foi um período favorável à formação de grupos musicais amadores vidaguenses e à contratação de instrumentistas profissionais exteriores a Vidago. Neste contexto, os músicos eram entendidos como prestadores de serviços e estavam sujeitos à sazonalidade da actividade termal, não permitindo independência financeira. Assim sendo, os músicos viam-se forçados a conciliar o trabalho musical com outros empregos anuais. Usavam esse argumento para se revoltarem contra a obrigatoriedade da profissionalização e pagamento de cotas durante todo o ano ao Sindicato dos Nacional dos Músicos (SNM), pelo que evitavam a sindicalização ou, uma vez sindicalizados, atrasavam sistematicamente o pagamento de cotas (Silva 2010; Fernandes 2018). Neste capítulo será abordado o estatuto dos músicos em Vidago entre 1933 e 1974, destacando as dinâmicas entre estes e as gerências dos hotéis, o SNM e a Casa do Povo local. Este estudo recorre a métodos da história e da etnomusicologia histórica, nomeadamente entrevistas a pessoas que assistiram às práticas musicais em estudo e pesquisa de arquivo no espólio do SNM (Howard 2014). Na linha que têm vindo a ser pensado na área da antropologia do turismo, considera-se que este é um fenómeno holístico, com implicações económicas, políticas, sociais, simbólicas e sonoras (Pinto e Pereiro 2010; Pereiro e Fernandes 2015; Sanchez e Carvalho 2019).

Breathe in for nothing: an interpretative phenomenological analysis exploring the influence of a Pilates warm-up in singers. An overview of the study

description: Research on the use of Pilates for classical singers is limited, despite the well-documented benefits of this somatic (mind-body) exercise modality on the general public. This study sought to ascertain the mental, physical and vocal benefits of a Pilates warm-up on four university singing students and one professional singer using Interpretative Phenomenological Analysis (IPA). A Pilates warm-up for singers was taught to the participants over six weeks, with three workshops of five days each interspersed with home practice. The effects thereof were documented, before-and-after questionnaires (GAD-7, Becks Depression Inventory and the RAND 36-Item short-form quality of life survey instrument) were completed, heart rate measurements taken (to determine if the warm-up initiated a parasympathetic nervous system response) and three semi-structured interviews were conducted with each participant. A focus group was then held with the participants to discuss the effects of the regime. The lived experience of the participants’ use of the Pilates warm-up was analysed and together with the collected data, was grouped into sub-themes named: Singing; Wellbeing; Preparation for Singing/Preparing the Body to Sing; Tools; Resilience; Mindfulness; Mind-Body Communication; Nervous System; Strengthening the Body; Relaxation through Movement and Pilates Breathing. In the cyclical interpretative process of an IPA, these sub themes were then grouped to form the main themes of the study, namely: Tools; Nervous System and Singing. The results showed an overall improvement in the quality of life as well as an increase in mindfulness and relaxation which benefitted all of the singers vocally in some way. Heart rate measurements and anxiety and depression scores showed a generally positive trend, although these results were inconclusive and require further study. The Pilates warm-up provided the singers with specific tools with which to address their various issues which had an impact on their singing. Performance preparation and posture were found to be enhanced, as well as reduced muscle tension, increased vocal range and improvements in stamina and breathing. This study highlights the potential benefits of the use of a Pilates warm-up for classical singers and the areas of research that should be undertaken to further delineate these benefits.

Structures compounds 1 and 2 were determined with the help of spectroscopic studies. Compound 1 showed strong antibacterial activity (21.0 ± 0.06 mm) against P. aeruginosa. Compounds 1 and 2 were also active against human breast carcinoma cells (MCF-7) with LC50 values of 49 ± 1.6 and 57.5 ± 1.5 μg/ml, respectively. This bioactivity was comparable to the currently used anticancer agent, cisplatin (LC50 46 ± 1.1 µg/ml). Compounds 1 and 2 exhibited anti-α-glucosidase activity with IC50 values of 58 ± 0.8 and 55 ± 0.5 µg/ml, respectively, whereas IC50 of Acarbose as a positive control was found to be 36 ± 0.4 µg/ml in our bioassay.
“Este som que se sente cá dentro!”: um estudo etnomusicológico sobre os bombos portugueses
Creators: name: Wink, Lucas
Publisher: name: Post-ip: Revista do Fórum Internacional de Estudos em Música e Dança
Year: 2020

description: Este é um estudo de doutoramento em curso centrado nos bombos portugueses sustentado em referencial teórico dos Sound Studies. Bombos é um termo que diz respeito a:1) um instrumento de percussão com uma organologia própria; 2) um conjunto de instrumentos formado por bombos, caixas e, em alguns contextos, por um instrumento melódico como o pífaro, a gaita de foles, a concertina e/ou o acordeão; 3) uma prática performativa predominantemente masculina, coletiva, intergeracional integrada às festividades locais. O estudo enfoca na observação, participação e análise juntamente ao Grupo Regional de São Simão Os Completos e ao Grupo de Bombos da Casa do Povo do Paul. Na escassa literatura específica da prática, são recorrentes as narrativas que, num olhar muito circunscrito de música, sublinham o “barulho”, o “estrondo atroador”, o “estrépito que afugenta” produzido por uma “orquestra diabólica” através da “reunião infernal de vários instrumentos de percussão” que fazem uma “música sem música” (Pimentel 1902; Lambertini 1902; Herculano 1855 in Braga 1885; Oliveira 1966). Stasi (1998) e Santos (2015) aludem precisamente às apreciações essencialistas que depreciam a percussão sob a premissa de ser excessivamente simples e defeituosa. Considerando que nas duas localidades os bombos são centrais na garantia do bem-estar e preservação da memória coletiva, juntando-se os grupos regularmente para ensaios e performances, justificando a manutenção de construtores artesanais e a transmissão de saberes específicos, este estudo tenciona sobrepujar estes juízos. Sugere, por isso, que os bombos devem ser perspectivados não em termos do seu barulho, mas da potencialidade e do impacto do seu som na vida social local (Feld 1990, 2004, 2012; Erlmann 2004; Sterne 2012; Stoller 1989). O trabalho de campo preliminar revela, nesse sentido, o intenso sentido que a prática e o som destes instrumentos têm para os atores locais. António Duarte, por exemplo, tocador de bombos do Paul, apontando para dentro do peito, elucida essa circunstância ao sintetizar a sua experiência na frase “este som que se sente cá dentro!”.

description: We present all-order expressions for the leading double-logarithmic threshold contributions to the quark-gluon coefficient functions for inclusive Higgs-boson production in the heavy top-quark limit and for Drell-Yan lepton-pair production. These results have been derived using the structure of the unfactorized cross sections in dimensional regularization and the large-x resummation of the gluon-quark and quark-gluon splitting functions. The resummed coefficient functions, which are identical up to colour factor replacements, are similar to their counterparts in deep-inelastic scattering but slightly more complicated.

Quickest detection of a hidden target and extremal surfaces

description: Let $Z=(Z_t)_{t\ge0}$ be a regular diffusion process started at $0$, let $\ell$ be an independent random variable with a strictly increasing and continuous distribution function $F$, and let $τ_{\ell}=\inf\{t\ge0\vert Z_t=\ell\}$ be the first entry time of $Z$ at the level $\ell$. We show that the quickest detection problem \[\inf_τ\bigl[\mathsf{P}(τ0$. Solving the latter problem we find that the following stopping time is optimal: \[τ_*=\inf \bigl\{t\ge0\vert f_*(I_t,S_t)\le X_t\le g_*(I_t,S_t)\bigr\},\] where the surfaces $f_*$ and $g_*$ can be characterised as extremal solutions to a couple of first-order nonlinear PDEs expressed in terms of the infinitesimal characteristics of $X$ and $c$. This is done by extending the arguments associated with the maximality principle [Ann. Probab. 26 (1998) 1614-1640] to the three-dimensional setting of the present problem and disclosing the general structure of the solution that is valid in all particular cases. The key arguments developed in the proof should be applicable in similar multi-dimensional settings.

description: We extend the {\sl\,PARSEC} library of stellar evolutionary tracks by computing new models of massive stars, from 14\Msun to 350\Msun. The input physics is the same used in the {\sl\,PARSEC}~V1.1 version, but for the mass-loss rate which is included by considering the most recent updates in literature. We focus on low metallicity, $Z$=0.001 and $Z$=0.004, for which the metal poor dwarf irregular star forming galaxies, Sextans A, WLM and NCG6822, provide simple but powerful workbenches. The models reproduce fairly well the observed CMDs but the stellar colour distributions indicate that the predicted blue loop is not hot enough in models with canonical extent of overshooting. In the framework of a mild extended mixing during central hydrogen burning, the only way to reconcile the discrepancy is to enhance the overshooting at the base of the convective envelope (EO) during the first dredge-UP. The mixing scales required to reproduce the observed loops, EO=2\HP or EO=4\HP, are definitely larger than those derived from, e.g., the observed location of the RGB bump in low mass stars. This effect, if confirmed, would imply a strong dependence of the mixing scale below the formal Schwarzschild border, on the stellar mass or luminosity. Reproducing the features of the observed CMDs with standard values of envelope overshooting would require a metallicity significantly lower than the values measured in these galaxies. Other quantities, such as the star formation rate and the initial mass function, are only slightly sensitive to this effect. Future investigations will consider other metallicities and different mixing schemes.

description: The first phytochemical analysis on the leaves of Agathis microstachya J.F. Bailey & C.T. White collected in Rome was reported in this work. The study evidenced the presence of four compounds i.e., 7,4'''-dimethoxy-agathisflavone (1), 7,7''-dimethoxy-cupressuflavone (2), dactylifric acid (3) and shikimic acid (4) which were identified by means of spectroscopic techniques. Compounds (1, 2, 4) were reported in the species for the first time as well as this is the second report on the presence of dactylifric acid (3) in the whole Araucariaceae family. The absence of diterpenoids from the studied accession is also important. All these chemotaxonomic aspects were discussed.
Double strangeness molecular-type pentaquarks from coupled channel dynamics

description: The existence of pentaquarks with strangeness content zero and one are major discoveries of the latest years in hadron physics. Most of these states can be understood as hadronic molecules and were predicted prior to their discovery within a model based on unitarized meson-baryon amplitudes obtained from vector meson exchange interactions. Contrary to earlier statements, we show this model to also predict the existence of pentaquarks with double strangeness, at about 4500 MeV and 4600 MeV, which are generated in a very specific and unique mechanism, via an attraction induced by a strong coupling between the two heaviest meson-baryon states.

description: Event-by-event fluctuations of global observables in relativistic heavy-ion collisions are studied as probes for the QCD phase transition and as tools to search for critical phenomena near the phase boundary. Dynamical fluctuations in mean transverse momentum, identified particle ratios and conserved quantities (such as net-charge, net-baryon) are expected to provide signatures of a de-confined state of matter. Non-monotonic behavior in the higher-moments of conserved quantities as a function of beam energy and collision centrality are proposed as signatures of the QCD critical point. To study the QCD phase transition and locate the critical point, the STAR experiment at RHIC has collected a large amount of data for Au+Au collisions from $\sqrt{s_{NN}} = 7.7-200$~GeV in the RHIC Beam Energy Scan (BES) program. We present the recent beam energy scan results on dynamical fluctuations of particle ratios and two-particle transverse momentum correlations at mid-rapidity. Higher-moments of the net-charge and net-proton multiplicity distributions as a function of beam energy will be presented. We give a summary of what has been learnt so far and future prospectives for the BES-II program.

description: We perform a high-resolution cosmological zoom-in simulation of a Milky Way (MW)--like system, which includes a realistic Large Magellanic Cloud analog, using a large differential elastic dark matter self-interaction cross section that reaches $\approx 100~\mathrm{cm}^2\ \mathrm{g}^{-1}$ at relative velocities of $\approx 10~\mathrm{km\ s}^{-1}$, motivated by the diverse and orbitally dependent central densities of dwarf galaxies within and surrounding the MW. We explore the effects of dark matter self-interactions on satellite, splashback, and isolated halos through their abundance, central densities, maximum circular velocities, orbital parameters, and correlations between these variables. We use an effective constant cross section model to analytically predict the stages of our simulated halos' gravothermal evolution, demonstrating that deviations from the collisionless $R_{\rm max}$--$V_{\rm max}$ relation can be used to select deeply core-collapsed halos, where $V_{\rm max}$ is a halo's maximum circular velocity, and $R_{\rm max}$ is the radius at which it occurs. We predict that a sizable fraction ($\approx 20\%$) of subhalos with masses down to $\approx 10^8~M_{\odot}$ is deeply core collapsed in our SIDM model. Core-collapsed systems form $\approx 10\%$ of the isolated halo population down to the same mass; these isolated, core-collapsed halos would host faint dwarf field galaxies with extremely steep central density profiles. Finally, most halos with masses above $\approx 10^9~M_{\odot}$ are core-forming in our simulation. Our study thus demonstrates how self-interactions diversify halo populations in an environmentally dependent fashion within and surrounding MW-mass hosts, providing a compelling avenue to address the diverse dark matter distributions of observed dwarf galaxies.

PANDEIRO DE NÁILON: O estilo interpretativo de Bira Presidente

description: A partir de 1972, quando o Bloco Carnavalesco Cacique de Ramos começava a promover rodas de samba em sua sede às quartas-feiras, um espaço fora do período carnavalesco surgiu para que os sambistas pudessem expor suas composições. Esse movimento, conhecido como “Pagode”, revelou notáveis músicos, compositores, assim como originou o Grupo Fundo de Quintal. O intuito principal da pesquisa é compreender como Bira Presidente – figura central desse movimento – executou o pandeiro de náilon no disco “De Pé No Chão” (RCA 1978). O álbum em questão apresenta extrema relevância pois foi a primeira vez que instrumentos como o repique de mão[1] e o banjo com afinação de cavaquinho foram gravados em um disco, e que atualmente são extremamente comuns no samba (Reis 2003, Silva 2013). Através de uma pesquisa documental videográfica, foi possível encontrar materiais onde se pode observar detalhes relativos à movimentação do instrumento, digitações e tipo de instrumento utilizado por Bira Presidente, o que seria bastante dificultoso, se não inviável, apenas com a audição dos fonogramas. Neste estudo de caso, foram feitas transcrições de trechos contrastantes da execução do pandeiro em três faixas a fim de compreender o idiomatismo presente no estilo interpretativo de Bira Presidente, evidenciando a riqueza de “levadas”[2]. Para isso, optei pela notação para pandeiro desenvolvida Stasi e Ferreira (2019), que representa com apenas duas linhas os timbres mais utilizados no pandeiro. [1] Instrumento de percussão tradicionalmente executado com a mão esquerda percutindo o corpo metálico do instrumento e a mão direita a pele (para os destros). Os golpes na pele são feitos com a alternância do polegar e os demais dedos da mão, gerando sons médio e agudos. [2] Padrão rítmico utilizado pelo instrumentista ao acompanhar uma determinada música.

description: Flavor changing neutral current $|ΔB|=|ΔS|=1$ processes are sensitive to possible new physics at the electroweak scale and beyond, providing detailed information about flavor, chirality and Lorentz structure. Recently the LHCb collaboration announced a $2.6 σ$ deviation in the measurement of $R_K={\cal{B}}(\bar B \to \bar K μμ)/{\cal{B}}(\bar B \to \bar K ee)$ from the standard model's prediction of lepton universality. We identify dimension six operators which could explain this deviation and study constraints from other measurements. Vector and axial-vector four-fermion operators with flavor structure $\bar s b \bar \ell \ell$ can provide a good description of the data. Tensor operators cannot describe the data. Pseudo-scalar and scalar operators only fit the data with some fine-tuning; they can be further probed with the $\bar B \to \bar K ee$ angular distribution. The data appears to point towards $C_9^{\rm NP μ} = -C_{10}^{\rm NP μ}<0$, an $SU(2)_{L}$ invariant direction in parameter space supported by $R_K$, the $\bar B \to \bar K^* μμ$ forward-backward asymmetry and the $\bar B_s \to μμ$ branching ratio, which is currently allowed to be smaller than the standard model prediction. We present two leptoquark models which can explain the FCNC data and give predictions for the LHC and rare decays.

description: São inúmeros os autores que legitimam a relevância da técnica do arco na performance do violino: Galamian (1962); Auer (1925); Viotti (cit. in Salles1998); Salles (1998); Gerle (2011); Mozart (1951 cit. in Gerle 2011); Capet (1916 cit. in Gerle 2011); Flesch (1928); Casorti (1880), e Pinto (2016). Desta forma, o principal objetivo deste estudo centra-se na compreensão dos movimentos somáticos necessários para reprodução dos diferentes golpes de arco. Através de uma investigação experimental em laboratório que envolveu 30 violinistas, foi possível a gravação - em formato de som, vídeo e Motion Capture, de um total de 1260 interpretações, resultado de uma criteriosa seleção de 42 excertos musicais representativos de cada um dos golpes de arco em estudo. Todas as gravações de som foram sujeitas à apreciação de um júri, que selecionou a melhor interpretação de cada excerto do grupo 1 (participantes com fato), a melhor interpretação do grupo 2 (participantes sem fato), e a pior interpretação de ambos os grupos. No caso específico do Son Filé, representado por um excerto musical do 2º Andamento da Sonata “Kreutzer”, op. 47 (Salles 1998, 60), o júri selecionou a interpretação dos participantes nº4 e nº14 como as melhores interpretações do grupo 1 e 2, respetivamente, e a interpretação nº 15 como a pior interpretação de ambos os grupos. Através da análise dos vídeos das interpretações supracitadas, constatou-se que a interpretação nº4 e nº14 coincidem em todos os componentes em análise (inclinação do arco, velocidade do arco, distância do cavalete, movimento do braço, movimento do pulso e direção do arco), e que a interpretação nº15 difere das restantes na inclinação do arco, velocidade do arco, movimento do pulso e direção do arco. Todas as interpretações captadas foram ainda analisadas ao pormenor através dos dados recolhidos no Motion Capture e passaram pelo mesmo processo de análise. Esta pesquisa concretiza-se no âmbito do projeto de doutoramento: “O ARCO – A Padronização Gestual dos Golpes de Arco para o Ensino-Aprendizagem do Violino”, com o objetivo final de se alcançarem padronizações gestuais dos diferentes golpes de arco no repertório mainstream de violino, coadjuvando violinistas e professores de violino.

description: The 4G Long Term Evolution (LTE) is the cellular technology expected to outperform the previous generations and to some extent revolutionize the experience of the users by taking advantage of the most advanced radio access techniques (i.e. OFDMA, SC-FDMA, MIMO). However, the strong dependencies between user equipments (UEs), base stations (eNBs) and the Evolved Packet Core (EPC) limit the flexibility, manageability and resiliency in such networks. In case the communication links between UEs-eNB or eNB-EPC are disrupted, UEs are in fact unable to communicate. In this article, we reshape the 4G mobile network to move towards more virtual and distributed architectures for improving disaster resilience, drastically reducing the dependency between UEs, eNBs and EPC. The contribution of this work is twofold. We firstly present the Flexible Management Entity (FME), a distributed entity which leverages on virtualized EPC functionalities in 4G cellular systems. Second, we introduce a simple and novel device-todevice (D2D) communication scheme allowing the UEs in physical proximity to communicate directly without resorting to the coordination with an eNB.

description: The European Commission (EC) unveiled its Farm to Fork and Biodiversity Strategies that would impose restrictions on European Union (EU) agriculture through targeted reductions in the use of land, fertilizers, antimicrobials, and pesticides. The proposal also pledges to use EC trade policies and other international efforts to support this vision of sustainable agri-food systems, suggesting intentions to expand the reach of the policy beyond the EU. To examine the economic implications of the proposal, we performed a range of policy simulations on several of the proposed targets using three progressively broader adoption scenarios of the EC’s initiative. Under all these scenarios, we found that the proposed input reductions affect EU farmers by reducing their agricultural production by 7 to 12 percent and diminishing their competitiveness in both domestic and export markets. Moreover, we found that adoption of these strategies would have impacts that stretch beyond the EU, driving up worldwide food prices by 9 (EU only adoption) to 89 percent (global adoption), negatively affecting consumer budgets, and ultimately reducing worldwide societal welfare by $96 billion to $1.1 trillion, depending on how widely other countries adopt the strategies. We estimate that the higher food prices under these scenarios would increase the number of food-insecure people in the world’s most vulnerable regions by 22 million (EU only adoption) to 185 million (global adoption).

description: In this letter, we investigate the tradeoff between energy efficiency (EE) and spectral efficiency (SE) in device-to-device (D2D) communications underlaying cellular networks with uplink channel reuse. The resource allocation problem is modeled as a noncooperative game, in which each user equipment (UE) is self-interested and wants to maximize its own EE. Given the SE requirement and maximum transmission power constraints, a distributed energy-efficient resource allocation algorithm is proposed by exploiting the properties of the nonlinear fractional programming. The relationships between the EE and SE tradeoff of the proposed algorithm and system parameters are analyzed and verified through computer simulations.
