Medicinal flora

description: The government of Pakistan has launched a massive afforestation campaign to revive the depleting state of forests of the province for this purpose an ambitious project was initiated knows as the "Billion Tree Afforestation Project" or BTAP. The project aims at planning, designing, commencing and implementing "Green Growth Initiative" in the Forestry Sector of Khyber Pakhtunkhwa Province. A study on the impact of BTAP project on medicinal flora of JARED sub division was conducted. The aim of the study was to assess the impacts of BTAP project on medicinal plants of JARED sub division. The methodology of the study focused on a series of surveys to find out the regeneration status and diversity of medicinal plants inside and outside the BTAP project area (enclosures). The study revealed 11 important medicinal plants which are present both inside and outside enclosures. Further the study reveals that a total of 6779 medicinal plants were present in the survey area inside enclosures and a total of 1328 medicinal plants were present in study area outside the enclosures. Further calculations were done to find out the Relative Cover and Relative frequency of medicinal plants in study area. The results of these calculations show that Relative cover of all medicinal plants inside enclosure area was 68% while outside enclosure area was 34.75%. Similarly, the results from calculations show relative frequency sum as 154 for inside enclosures and 69 for outside of enclosure area. The research has shown massive regeneration and intensity of medicinal flora on the sites upon which BTAP activities were done. The formation of closures specifically has really enhanced growth of medicinal flora, in comparison with open sites the density of medicinal flora in closures is greater. The field data that is collected shows 2-3 times more number of medicinal plants on BTAP sites than elsewhere. Not only are the numbers greater on BTAP sites but also the diversity of medicinal flora on BTAP sites is greater. The study also reveals that through this project a great number of species are being conserved in situ through the formation of enclosures.

description: A first measurement of the polarisation transfer from a circularly-polarised photon to the final state neutron ($C^n_{x'}$) in deuterium photodisintegration has been carried out. This quantity is determined over the photon energy range 370~--~700~MeV and for neutron centre-of-mass breakup angles $\sim45-120^{\circ}$. The polarisation of the final state neutrons was determined by an ancillary large-acceptance nucleon polarimeter, surrounding a cryogenic liquid deuterium target within the Crystal Ball detector at MAMI. The polarimeter characterised $(n,p)$ charge exchange of the ejected neutrons to determine their polarisation. The new $C^n_{x'}$ data are also compared to a theoretical model based on nucleonic and nucleon resonance degrees of freedom constrained by the current world-database of deuterium photodisintegration measurements. Structures in $C^n_{x'}$ observed in the region of the $d^*(2380)$ could not be explained by conventional models of deuteron photodisintegration.

description: In this article, we analyse how decentralised digital infrastructures can provide a fundamental change in the structure and dynamics of organisations. The works of R.H.Coase and M. Olson, on the nature of the firm and the logic of collective action, respectively, are revisited under the light of these emerging new digital foundations. We also analyse how these technologies can affect the fundamental assumptions on the role of organisations (either private or public) as mechanisms for the coordination of labour. We propose that these technologies can fundamentally affect: (i) the distribution of rewards within an organisation and (ii) the structure of its transaction costs. These changes bring the potential for addressing some of the trade-offs between the private and public sectors.

description: O turismo, enquanto atividade económica, tem sido tema de muitos debates acerca do desenvolvimento socioeconómico mundial. Este estudo propõe uma discussão da atividade na Ilha de Santa Catarina, no Sul do Brasil, segmentada para o público homossexual, relacionando sociedade de consumo e lugar turístico a partir do método etnográfico, com observação participante e entrevistas semiestruturadas, realizadas entre 2010 e 2011, num bar e numa praia de nudismo. A Ilha desponta no desenvolvimento do turismo homossexual, denominado por categoria nativa e pelos meios de comunicação turística nacionais e internacionais, de “turismo gay”. Os resultados obtidos revelaram que as principais motivações de procura por este tipo de turismo se prendem com a liberdade sexual, a segurança local e o anonimato que o turismo propícia, permitindo satisfazer os desejos de sexo rápido sem compromisso, longe dos estigmas sociais quotidianos.

description: Symmetries play a crucial role in the classification of topological phases of matter. Although recent studies have established a powerful framework to search for and classify topological phases based on symmetry indicators, there exists a large class of fragile topology beyond the description. The Euler class characterizing the topology of two-dimensional real wave functions is an archetypal fragile topology underlying some important properties, such as non-Abelian braiding of crossing nodes and higher-order topology. However, as a minimum model of fragile topology, the two-dimensional topological Euler insulator consisting of three bands remains a significant challenge to be implemented in experiments. Here, we experimentally realize a three-band Hamiltonian to simulate a topological Euler insulator with a trapped-ion quantum simulator. Through quantum state tomography, we successfully evaluate the Euler class, Wilson loop flow and entanglement spectra to show the topological properties of the Hamiltonian. We also measure the Berry phases of the lowest energy band, illustrating the existence of four crossing points protected by the Euler class. The flexibility of the trapped-ion quantum simulator further allows us to probe dynamical topological features including skyrmion-antiskyrmion pairs and Hopf links in momentum-time space from quench dynamics. Our results show the advantage of quantum simulation technologies for studying exotic topological phases and open a new avenue for investigating fragile topological phases in experiments.

description: The sporadic large fluctuations are seen in the stock market due to changes in fundamental parameters, technical setups, and external factors. These large fluctuations are termed as Extreme Events (EE). The EEs may be positive or negative depending on the impact of these factors. During such events, the stock price time series is found to be nonstationary. Hence, the Hilbert-Huang transformation (HHT) is used to identify EEs based on their high instantaneous energy ($IE$) concentration. The analysis shows that the $IE$ concentration in the stock price is very high during both positive and negative EE with $IE>E_μ+4σ,$ where $E_μ$ and $σ$ are the mean energy and standard deviation of energy, respectively. Further, support vector regression is used to predict the stock price during an EE, with the close price being the most helpful input than the open-high-low-close (OHLC) inputs. The maximum prediction accuracy for one step using close price and OHLC prices are 95.98\% and 95.64\% respectively. Whereas, for the two steps prediction, the accuracies are 94.09\% and 93.58\% respectively. The EEs found from the predicted time series shows similar statistical characteristics that were obtained from the original data. The analysis emphasizes the importance of monitoring factors that lead to EEs for a compelling entry or exit strategy as investors can gain or lose significant amounts of capital due to these events.

description: Very long baseline interferometry (VLBI) monitoring of the 6.7 GHz methanol maser allows us to measure the internal proper motions of the maser spots and therefore study the gas motion around high-mass young stellar objects. To this end, we have begun monitoring observations with the East-Asian VLBI Network. In this paper we present the results of the first epoch observation for 36 sources, including 35 VLBI images of the methanol maser. Since two independent sources were found in three images, respectively, images of 38 sources were obtained. In 34 sources, more than or equal to 10 spots were detected. The observed spatial scale of the maser distribution was from 9 to 4900 astronomical units, and the following morphological categories were observed: elliptical, arched, linear, paired, and complex. The position of the maser spot was determined to an accuracy of approximately 0.1 mas, sufficiently high to measure the internal proper motion from two years of monitoring observations. The VLBI observation, however, detected only approximately 20% of all maser emission, suggesting that the remaining 80% of the total flux was spread into an undetectable extended distribution. Therefore, in addition to high-resolution observations, it is important to observe the whole structure of the maser emission including extended low-brightness structures, to reveal the associated site of the maser and gas motion.

description: We explore the effects of stochastic resetting to random positions of a Brownian particle on first passage times and Shannon's entropy. We explore the different entropy regimes, namely, the \textit{externally-driven}, the \textit{zero-entropy} and the \textit{Maxwell demon} regimes. We show that the mean first passage time (MPFT) minimum can be found in any of these regimes. We provide a novel analytical method to compute the MFPT, the mean first passage number of resets (MFPNR) and mean first passage entropy (MFPE) in the case where the Brownian particle resets to random positions sampled from a set of distributions known \textit{a priori}. We show the interplay between the reset position distribution's second moment and the reset rate, and the effect it has on the MFPT and MFPE. We further propose a mechanism whereby the entropy per reset can be either in the Maxwell demon or the externally driven regime, yet the overall mean first passage entropy corresponds to the zero-entropy regime. Additionally, we find an overlap between the dynamic phase space and the entropy phase space. We use this method in a generalized version of the Evans-Majumdar model by assuming the reset position is random and sampled from a Gaussian distribution. We then consider the \textit{toggling reset} whereby the Brownian particle resets to a random position sampled from a distribution dependent on the reset parity. All our results are compared to and in agreement with numerical simulations.

description: Este artigo tem como objetivo demonstrar que os emigrantes portugueses, enquanto potenciais promotores turísticos, poderão contribuir para impulsionar as etapas iniciais do desenvolvimento económico das áreas rurais em Portugal. Este pressuposto é válido se tivermos em consideração, por um lado, os vários estudos realizados, em países em vias de desenvolvimento e áreas rurais, reveladores de que as despesas turísticas criam mais emprego e rendimento do que qualquer outro setor da economia, pelo seu efeito multiplicador e a sua ligação a praticamente todas as outras indústrias da economia. Por outro lado, os resultados preliminares de um estudo recente realizado entre os emigrantes portugueses (diretos) corroboram parte daquele argumento ao considerarmos a sua idade, grau escolar e capital, obtidos durante a emigração, bem como a possibilidade de pretenderem regressar, investir num negócio e ter um emprego na área do turismo, no seu local de origem, em Portugal.

description: The density and temperature structures of dense cores in the L1495 cloud of the Taurus star-forming region are investigated using Herschel SPIRE and PACS images in the 70 $μ$m, 160 $μ$m, 250 $μ$m, 350 $μ$m and 500 $μ$m continuum bands. A sample consisting of 20 cores, selected using spectral and spatial criteria, is analysed using a new maximum likelihood technique, COREFIT, which takes full account of the instrumental point spread functions. We obtain central dust temperatures, $T_0$, in the range 6-12 K and find that, in the majority of cases, the radial density falloff at large radial distances is consistent with the $r^{-2}$ variation expected for Bonnor-Ebert spheres. Two of our cores exhibit a significantly steeper falloff, however, and since both appear to be gravitationally unstable, such behaviour may have implications for collapse models. We find a strong negative correlation between $T_0$ and peak column density, as expected if the dust is heated predominantly by the interstellar radiation field. At the temperatures we estimate for the core centres, carbon-bearing molecules freeze out as ice mantles on dust grains, and this behaviour is supported here by the lack of correspondence between our estimated core locations and the previously-published positions of H$^{13}$CO$^+$ peaks. On this basis, our observations suggest a sublimation-zone radius typically $\sim 10^4$ AU. Comparison with previously-published N$_2$H$^+$ data at 8400 AU resolution, however, shows no evidence for N$_2$H$^+$ depletion at that resolution.

description: Este artigo tem como objetivo analisar o desenvolvimento da atividade turística da região nordeste do Brasil. Para a análise dos dados foi utilizado o método estatístico descritivo e o método comparativo. Através do PRODETUR/NE verificou-se uma redução das barreiras que dificultavam o desenvolvimento da atividade turística na região nordeste, sobretudo as relacionados com as infraestruturas turísticas. As principais capitais do nordeste, Salvador, Recife e Fortaleza, ocupavam, em 2003, a 3ª, 4ª e 5ª posições no ranking das cidades mais visitadas do Brasil. Houve um incremento no número de passageiros desembarcados nos aeroportos nordestinos, considerado como indicador do fluxo turístico. A capacidade instalada da rede hoteleira nas capitais do nordeste registrou um aumento de 94%, de 1996 a 2009, e a região apresentou uma taxa de ocupação superior a 63%, bastante próxima da média nacional. A receita turística no nordeste brasileiro aumentou, em média, 97% no período 2002-2008. Observou-se, ainda, que 43% dos investimentos portugueses no Brasil foram realizados na região nordeste do Brasil e que 69% das empresas portuguesas no Brasil atuam no setor de serviços, das quais 15% pertencem ao setor hoteleiro. A partir do cenário exposto, depreende-se que o turismo se tornou uma atividade estratégica para o nordeste, na medida em que atrai novos investimentos e cria novas oportunidades de negócios e de trabalho, permitindo compatibilizar o crescimento económico, o desenvolvimento social do seu povo, bem como a preservação dos recursos e belezas naturais da região.

description: Este artigo procura demonstrar que o debate acerca das relações entre turismo e ética não pode ser reduzido à controvérsia sobre o ecoturismo e focado na contradição entre turismo de massas e ecoturismo. No seu quadro de análise, considera as fontes filosóficas adotadas pelos defensores do ecoturismo e da Ética do turismo em geral, mas introduz também o novo paradigma da filosofia ambiental. Avalia ainda a evolução do mercado de turismo, no contexto das categorias de “motivação” e “gosto” e na sua ligação com as conferências das Nações Unidas sobre o ambiente, e com a génese do Código Mundial de Ética do Turismo. A sua principal tese é que a relação entre turismo e ética deve ser centrada na perspetiva da filosofia do ambiente e da sua ética, aplicada à atividade turística global e à sua conceptualização teórica. O artigo procede a uma mais rigorosa avaliação dos conceitos filosóficos aplicados ao turismo: natureza e ambiente, paisagem, deontologia, moral, ética, sustentabilidade, entre outros. Conclui que a atividade turística evoluiu qualitativamente, levando à coexistência, no mercado mundial, de diferentes paradigmas, com a clara ascensão do turismo cultural e do turismo de natureza. Demonstrada a relevância das relações entre a evolução do turismo e a Filosofia do Ambiente, o artigo enuncia alguns dos conceitos fundamentais da sua epistemologia e hermenêutica, e da sua ética.

description: Temporal social networks of human interactions are preponderant in understanding the fundamental patterns of human behavior. In these networks, interactions occur locally between individuals (i.e., nodes) who connect with each other at different times, culminating into a complex system-wide web that has a dynamic composition. Dynamic behavior in networks occurs not only locally but also at the global level, as systems expand or shrink due either to: changes in the size of node population or variations in the chance of a connection between two nodes. Here, we propose a numerical maximum-likelihood method to estimate population size and the probability of two nodes connecting at any given point in time. An advantage of the method is that it relies only on aggregate quantities, which are easy to access and free from privacy issues. Our approach enables us to identify the simultaneous (rather than the asynchronous) contribution of each mechanism in the densification and sparsification of human contacts, providing a better understanding of how humans collectively construct and deconstruct social networks.

description: A fraction of the heavily reddened quasars require a reddening curve which is even steeper than that of the Small Magellanic Cloud. In this paper, we thoroughly characterize the anomalously steep reddening law in quasars, via an exceptional example observed in IRAS 14026+4341. By comparing the observed spectrum to the quasar composite spectrum, we derive a reddening curve in the rest-frame wavelength range of 1200 Å--10000 Å. It is featured with a steep rise at wavelengths shorter than 3000 Å, but no significant reddening at longer wavelengths. The absence of dust reddening in optical continuum is confirmed by the normal broad-line Balmer decrement (the H$α$/H$β$ ratio) in IRAS 14026+4341. The anomalous reddening curve can be satisfactorily reproduced by a dust model containing silicate grains in a power-law size distribution, $dn(a)/da \propto a^{-1.4}$, truncated at a maximum size $a_{max}=70 {\rm nm}$. The unusual size distribution may be caused by the destruction of large "stardust" grains by quasar activities or a different dust formation mechanism (i.e., the in situ formation of dust grains in quasar outflows). It is also possible that the analogies of the dust grains observed toward the Galactic center is responsible for the steep reddening curve. In addition, we find that IRAS 14026+4341 is a weak emission-line quasar (i.e., PHL 1811 analogies) with heavy dust reddening and blueshifted broad absorption lines.

description: The school timetabling problem can be described as scheduling a set of lessons (combination of classes, teachers, subjects and rooms) in a weekly timetable. This paper presents a novel way to generate timetables for high schools. The algorithm has three phases. Pre-scheduling, initial phase and optimization through tabu search. In the first phase, a graph based algorithm used to create groups of lessons to be scheduled simultaneously; then an initial solution is built by a sequential greedy heuristic. Finally, the solution is optimized using tabu search algorithm based on frequency based diversification. The algorithm has been tested on a set of real problems gathered from Iranian high schools. Experiments show that the proposed algorithm can effectively build acceptable timetables.

description: Favela tourism in Rio de Janeiro is becoming increasingly popular, especially among international travellers. However, academic debates often condemn this type of tourism as a form of exploitative voyeurism. This article intends to clarify this phenomenon and explore the potential contribution of tourism for social transformation. Supporting the idea that tourism can be seen as a platform for dialogue and social change (Ateljevic, 2009). Residents can benefit from tourism in terms of intercultural understanding and increase of self-esteem (Smith and Robinson, 2006). This study is based on qualitative research done in two favelas: Rocinha and Pereira da Silva. Insights into the residents’ perception upon tourism development were obtained through participant observation and interviews. Results showed that under certain circumstances, favela tourism can indeed support processes of transformation in favelas. It can lead to a more realistic perception of favela residents and can stimulate socio-economic opportunities. Although acknowledging the complexity of tourism in vulnerable areas, this study shows that it can also make a positive contribution. The outcomes of this research bring a new light on the topic of favela tourism and to a better understanding of the complexity of favelas as an object of study.

description: Multi-photon lithography allows to complement planar photonic integrated circuits (PIC) by in-situ 3D-printed freeform waveguide structures. However, design and optimization of such freeform waveguides using time-domain Maxwell's equations solvers often requires comparatively large computational volumes, within which the structure of interest only occupies a small fraction, thus leading to poor computational efficiency. In this paper, we present a solver-independent transformation-optics-(TO-) based technique that allows to greatly reduce the computational effort related to modeling of 3D freeform waveguides. The concept relies on transforming freeform waveguides with curved trajectories into equivalent waveguide structures with modified material properties but geometrically straight trajectories, that can be efficiently fit into rather small cuboid-shaped computational volumes. We demonstrate the viability of the technique and benchmark its performance using a series of different freeform waveguides, achieving a reduction of the simulation time by a factor of 3-6 with a significant potential for further improvement. We also fabricate and experimentally test the simulated waveguides by 3D-printing on a silicon photonic chip, and we find good agreement between the simulated and the measured transmission at $λ= 1550 \textrm{ nm}$.

description: We demonstrate that in a class of disordered quantum systems the dynamical partition function is not an analytical function in a time window after certain quantum quenches. We related this behavior to rare and large regions with atypical inhomogeneity configurations. We also quantify the strength of the associated singularities and their signatures in experiments and numerical studies.

description: It is well-documented how artificial intelligence can have (and already is having) a big impact on chemical engineering. But classical machine learning approaches may be weak for many chemical engineering applications. This review discusses how challenging data characteristics arise in chemical engineering applications. We identify four characteristics of data arising in chemical engineering applications that make applying classical artificial intelligence approaches difficult: (1) high variance, low volume data, (2) low variance, high volume data, (3) noisy/corrupt/missing data, and (4) restricted data with physics-based limitations. For each of these four data characteristics, we discuss applications where these data characteristics arise and show how current chemical engineering research is extending the fields of data science and machine learning to incorporate these challenges. Finally, we identify several challenges for future research.

description: For the Fröhlich model of the large polaron, we prove that the ground state energy as a function of the total momentum has a unique global minimum at momentum zero. This implies the non-existence of a ground state of the Fröhlich Hamiltonian and thus excludes the possibility of a localization transition at finite coupling.

description: In recent years, many researchers have focused on wireless sensor networks and their applications. To obtain scalability potential in these networks most of the nodes are categorized as distinct groups named cluster and the node which is selected as cluster head or Aggregation Node offers the operation of data collection from other cluster nodes and aggregation and sending it to the rest of the network. Clustering and data aggregation increase network scalability and cause that limited resources of the network are used well. However, these mechanisms also make several breaches in the network, for example in clustered networks cluster head nodes are considered Desirable and attractive targets for attackers since reaching their information whether by physical attack and node capturing or by other attacks, the attacker can obtain the whole information of corresponding cluster. In this study secure clustering of the nodes are considered with the approach of reducing energy consumption of nodes and a protocol is presented that in addition to satisfying Advanced security needs of wireless sensor networks reduces the amount of energy consumption by the nodes. Due to network clustering there is scalability potential in such a network and According to frequent change of cluster head nodes load distribution is performed in the cluster and eventually increase the network lifetime.

description: CompCert is the first realistic formally verified compiler: it provides a machine-checked mathematical proof that the code it generates matches the source code. Yet, there could be loopholes in this approach. We comprehensively analyze aspects of CompCert where errors could lead to incorrect code being generated. Possible issues range from the modeling of the source and the target languages to some techniques used to call external algorithms from within the compiler.

description: Coronary heart disease (CHD), caused by atherosclerosis, is one of the main causes of disability and mortality throughout the world, including in Uzbekistan. This article represents the results of optomozes therapy of patients with stable angina based on the early diagnostics of renal dysfunction. As a result of treatment, positive clinical dynamics were observed in both groups, but in the second group this result was more pronounced. It has been shown that early detection of renal dysfunction markers and combined lipid-lowering agents in combination with traditional therapy in patients with stable angina is more reliably effective than monotherapy.

description: Social media platforms have been establishing content moderation guidelines and employing various moderation policies to counter hate speech and misinformation. The goal of this paper is to study these community guidelines and moderation practices, as well as the relevant research publications, to identify the research gaps, differences in moderation techniques, and challenges that should be tackled by the social media platforms and the research community. To this end, we study and analyze fourteen most popular social media content moderation guidelines and practices, and consolidate them. We then introduce three taxonomies drawn from this analysis as well as covering over two hundred interdisciplinary research papers about moderation strategies. We identify the differences between the content moderation employed in mainstream and fringe social media platforms. Finally, we have in-depth applied discussions on both research and practical challenges and solutions.

description: The energy loss pattern of a low momentum heavy quark in a deconfined quark-gluon plasma can be understood in terms of a Langevin description. In thermal equilibrium, the motion can then be parametrized in terms of a single heavy quark momentum diffusion coefficient kappa, which needs to be determined nonperturbatively. In this work, we study the temperature dependence of kappa for a static quark in a gluonic plasma, with a particular emphasis on the temperature range of interest for heavy ion collision experiments.
