description: La ‘forza’, intesa nella sua accezione di potenziale offensivo-difensivo attribuibile ad un corpo umano, è realmente un ‘dominio’ maschile? Se il senso comune sembra rispondere affermativamente, questo articolo propone per una tesi diversa. Attraverso una lettura non convenzionale del capitolo sulle Età dell’essere umano delle Etimologiae di Isidoro da Siviglia, si intende far emergere un’interpretazione inedita e originale della costruzione culturale del concetto di ‘forza’ relativa al genere. Questo costrutto, lungi dall’essere un dato naturale, si è esplicato come dispositivo bio-politico, profezia autorealizzantesi. Il concetto di ‘forza’ gioco un ruolo centrale nella costruzione delle identità maschili e femminili come asimmetriche. Ma la chiarezza del ‘dato naturale’ si mostra, invece, come un nebuloso costrutto, basato su di un’arbitraria divisione tra ‘natura’ e ‘cultura’, nesso questo, che necessita un profondo ripensamento. La ricognizione delle etimologie si presenta come terreno in cui impianti normanti riguardo alla donna si siano trasformati in ‘dati biologici’. All’interno di costruzioni artificiose è però possibile rintracciare un’altra storia, che come fiume carsico, riemerge dall’occultamento.

description: This paper proposes a control theoretic framework to model and analyze the self-organized pattern formation of molecular concentrations in biomolecular communication networks, emerging applications in synthetic biology. In biomolecular communication networks, bionanomachines, or biological cells, communicate with each other using a cell-to-cell communication mechanism mediated by a diffusible signaling molecule, thereby the dynamics of molecular concentrations are approximately modeled as a reaction-diffusion system with a single diffuser. We first introduce a feedback model representation of the reaction-diffusion system and provide a systematic local stability/instability analysis tool using the root locus of the feedback system. The instability analysis then allows us to analytically derive the conditions for the self-organized spatial pattern formation, or Turing pattern formation, of the bionanomachines. We propose a novel synthetic biocircuit motif called activator-repressor-diffuser system and show that it is one of the minimum biomolecular circuits that admit self-organized patterns over cell population.

description: Magnetic Weyl semimetal (WSM) is of great importance both for fundamental physics and potential applications due to its spontaneous magnetism, robust band topology, and enhanced Berry curvature. It possesses many unique quantum effects, including large intrinsic anomalous Hall effect, Fermi arcs, and chiral anomaly. In this work, using ab initio calculations, we propose that Ni doped pyrochlore Tl$_2$Nb$_2$O$_7$ is a magnetic WSM caused by exchange field splitting on bands around its quadratic band crossing point. The exchange field tuned by Ni 3d on-site Coulomb interaction parameter $U$ drives the evolution of Weyl nodes and the resulting topological phase transition. Since Weyl nodes can exist at generic point in Brillouin zone and are hard to be exactly identified, the creation and annihilation of them, i.e., the change in their number, chirality and distribution, have been consistently confirmed with a combined theoretical approach, which employs parity criterion, symmetry indicator analysis and the Wilson loop of Wannier center. We find that Weyl nodes remain in a quite large range of $U$ and are close to Fermi level, which makes the experimental observation very possible. We think this method and our proposal of magnetic WSM will be useful in finding more WSMs and adding our understanding on the topological phase transition.

description: We investigate the impact of site dilution by setting the on-site repulsion strength ($U$) to zero at a fraction of sites in the half-filled Hubbard model on a simple cubic lattice. We employ a semi-classical Monte-Carlo approach first to recover the zero dilution (undiluted $x=1$) properties, including $U$ dependence of insulator to metal crossover temperature scale $T^*$ and long-range staggered antiferromagnetic ordering temperature ($T_N$). For the non-perturbative regime of $U \sim$ bandwidth, we find a rapid suppression of $T^*$ with reducing $x$ from 1 to 0.7. However, $T_N$ remains unchanged in this dilution range, showing a weakening of the insulating state but not of the magnetic order. At $x \leq 0.7$, $T^*$ and $T_N$ coincide and are suppressed together with further increase in site-dilution. Finally, the system loses the magnetic order and the insulating state for $x=0.15$, significantly below the classical percolation threshold $x_p^{sc} (\sim 0.31$). We show that the induced moments on $U=0$ sites drive the magnetic order below the classical percolation limit by studying local moment systematics and finite-size analysis of magnetic order. At the end, we show that either increasing $U$ to large values or raising temperature beyond a $U$ dependent critical value, suppresses the induced local moments of the $U=0$ sites and recovers the classical percolation threshold.

description: Linear and substructural types are powerful tools, but adding them to standard functional programming languages often means introducing extra annotations and typing machinery. We propose a lightweight substructural type system design that recasts the structural rules of weakening and contraction as type classes; we demonstrate this design in a prototype language, Clamp. Clamp supports polymorphic substructural types as well as an expressive system of mutable references. At the same time, it adds little additional overhead to a standard Damas-Hindley-Milner type system enriched with type classes. We have established type safety for the core model and implemented a type checker with type inference in Haskell.

description: Both credit default swap (CDS) and options markets often experience ab-
normal swings prior to the announcement of negative credit news. With the
exclusion of negative earnings announcements, we find that options prices reveal
information about such forthcoming adverse events at least as early as do credit
spreads. Prior to negative credit news being publicly disclosed, we find that the
equity market does not respond to abnormal movement in options prices unless
that information has also manifested itself in the CDS market. A potential
explanation is that options are more likely to trade on unsubstantiated rumors
than are default swaps.

description: Environmental changes can alter the interactions between biotic and abiotic ecosystem components in tidal wetlands and therefore impact important ecosystem functions. The objective of this study was to determine how saltwater intrusion affects wetland nutrient biogeochemistry, with a specific focus on the soil microbial communities and physicochemical parameters that control nitrate removal. Our work took place in a tidal freshwater marsh in South Carolina, USA, where a 3.5-year saltwater intrusion experiment increased porewater salinities from freshwater to oligohaline levels. We measured rates of denitrification, soil oxygen demand, and dissimilatory nitrate reduction to ammonium (DNRA) and used molecular genetic techniques to assess the abundance and community structure of soil microbes. In soils exposed to elevated salinities, rates of denitrification were reduced by about 70% due to changes in the soil physicochemical environment (higher salinity, higher carbon:nitrogen ratio) and shifts in the community composition of denitrifiers. Saltwater intrusion also affected the microbial community responsible for DNRA, increasing the abundance of genes associated with this process and shifting microbial community composition. Though rates of DNRA were below detection, the microbial community response may be a precursor to increased rates of DNRA with continued saltwater intrusion. Overall, saltwater intrusion reduces the ability of tidal freshwater marshes to convert reactive nitrogen to dinitrogen gas and therefore negatively affects their water quality functions. Continued study of the interrelationships between biotic communities, the abiotic environment, and biogeochemical transformations will lead to a better understanding of how the progressive replacement of tidal freshwater marshes with brackish analogues will affect the overall functioning of the coastal landscape.
Forward-modelling the Luminosity, Distance, and Size distributions of the Milky Way Satellites

description: We use \texttt{GRUMPY}, a simple regulator-type model for dwarf galaxy formation and evolution, to forward model the dwarf galaxy satellite population of the Milky Way (MW) using the Caterpillar zoom-in simulation suite. We show that luminosity and distance distributions of the model satellites are consistent with the distributions measured in the DES, PS1 and SDSS surveys, even without including a model for the orphan galaxies. We also show that our model for dwarf galaxy sizes can simultaneously reproduce the observed {\it distribution} of stellar half-mass radii, $r_{1/2}$, of the MW satellites and the overall $r_{1/2}-M_\star$ relation exhibited by observed dwarf galaxies. The model predicts that some of the observed faint stellar systems with $r_{1/2}<10$ pc are ultra-faint dwarf galaxies. Scaling of the stellar mass $M_\star$ and peak halo mass $M_{\rm peak}$ for the model satellites is not described by a power law, but has a clear flattening of $M_\star-M_{\rm peak}$ scaling at $M_{\rm peak}<10^8\,M_\odot$ imprinted by reionization. As a result, the fraction of low mass haloes ($M_{\rm peak} < 10^8\, M_\odot$) hosting galaxies with $M_V<0$ is predicted to be 50% at $M_{\rm peak} \sim 3.6 \times 10^7\,M_\odot$. We find that such high fraction at that halo mass helps to reproduce the number of dwarf galaxies discovered recently in the HSC-SSP survey. Using the model we forecast that there should be the total of $440^{+201}_{-147}$ (68\% confidence interval) MW satellites with $M_V < 0$ and $r_{1/2} > 10$ pc within 300 kpc and make specific predictions for the HSC-SSP, DELVE-WIDE and LSST surveys.

description: Bell's Theorem shows that quantum mechanical correlations can violate the constraints that the causal structure of certain experiments impose on any classical explanation. It is thus natural to ask to which degree the causal assumptions -- e.g. locality or measurement independence -- have to be relaxed in order to allow for a classical description of such experiments. Here, we develop a conceptual and computational framework for treating this problem. We employ the language of Bayesian networks to systematically construct alternative causal structures and bound the degree of relaxation using quantitative measures that originate from the mathematical theory of causality. The main technical insight is that the resulting problems can often be expressed as computationally tractable linear programs. We demonstrate the versatility of the framework by applying it to a variety of scenarios, ranging from relaxations of the measurement independence, locality and bilocality assumptions, to a novel causal interpretation of CHSH inequality violations.

description: $f(R)$ theories of gravity are one of the most popular alternative explanations for dark energy and therefore studying the possible astrophysical implications of these theories is an important task. In the present paper we make a substantial advance in this direction by considering rapidly rotating neutron stars in $R^2$ gravity. The results are obtained numerically and the method we use is non-perturbative and self-consistent. The neutron star properties, such as mass, radius and moment of inertia, are studied in detail and the results show that rotation magnifies the deviations from general relativity and the maximum mass and moment of inertia can reach very high values. This observation is similar to previous studies of rapidly rotating neutron stars in other alternative theories of gravity, such as the scalar-tensor theories, and it can potentially lead to strong astrophysical manifestations.

description: In this paper, we study the prospect of ECAL barrel timing to develop triggers dedicated to long-lived particles decaying to jets, at the level-1 of HL-LHC. We construct over 20 timing based variables, and identify three of them which have better performances and are robust against increasing PU. We estimate the QCD prompt jet background rates accurately using the "stitching" procedure for varying thresholds defining our triggers, and compute the signal efficiencies for different LLP scenarios for a permissible background rate. The trigger efficiencies can go up to $\mathcal{O}(80\%)$ for the most optimal trigger for pair-produced heavy LLPs having high decay lengths, which degrades with decreasing mass and decay length of the LLP. We also discuss the prospect of including the information of displaced L1 tracks to our triggers, which further improves the results, especially for LLPs characterised by lower decay lengths.

description: In this paper, we study the user localization and tracking problem in the reconfigurable intelligent surface (RIS) aided multiple-input multiple-output (MIMO) system, where a multi-antenna base station (BS) and multiple RISs are deployed to assist the localization and tracking of a multi-antenna user. By establishing a probability transition model for user mobility, we develop a message-passing algorithm, termed the Bayesian user localization and tracking (BULT) algorithm, to estimate and track the user position and the angle-of-arrival (AoAs) at the user in an online fashion. We also derive Bayesian Cramér Rao bound (BCRB) to characterize the fundamental performance limit of the considered tracking problem. To improve the tracking performance, we optimize the beamforming design at the BS and the RISs to minimize the derived BCRB. Simulation results show that our BULT algorithm can perform close to the derived BCRB, and significantly outperforms the counterpart algorithms without exploiting the temporal correlation of the user location.

The Effects of Urbanization and Retention-Based Stormwater Management on Coastal Plain Stream Nutrient Export

Publisher: name: Blackwell Publishing Ltd
Year: 2019

description: Stormwater nutrient pollution can be more effectively managed if there is a predictable link between urbanization and pollutant export. The goal of this study was to determine the effects of increased watershed impervious surface cover (ISC) and retention-based stormwater management on stream discharge and nutrient export from coastal plain streams in the southeastern United States. To quantify coastal plain stream nutrient export, measurements of stream discharge and concentrations of dissolved nutrients, particulate nitrogen, and algal biomass (as chlorophyll a) were collected during baseflow and stormflow for four years from five streams on Marine Corps Base Camp Lejeune near Jacksonville, North Carolina. The study streams had watersheds that spanned a range of ISC (1–38%) and included an urban watershed drained extensively by stormwater ponds. Urban streams had higher rates of annual discharge than less impacted streams due to elevated discharge at all rates of flow, more cumulative discharge at high flows, and dampened seasonal patterns. Streams with higher watershed ISC had higher rates of annual export of all measured nutrients due to increased stream discharge and concentrations of inorganic and particulate nitrogen. The relative importance of dissolved organic nitrogen decreased with watershed ISC, but it was still the dominant form of nitrogen export in every study stream except the stream that was dominated by particulate nitrogen export from stormwater pond algal production. Based on these findings, this study suggests that stormwater management emphasizing stormwater harvesting and evapotranspiration, increased wetland area, and decreased anthropogenic nutrient sources could reduce nutrient export from urban coastal plain streams.

description: Electronic Lab Notebooks (ELNs) are a key prerequisite to a comprehensive documentation of research processes, the digital storage of research data, and their reuse. ELNs can be used to plan, record, store and - in combination with repositories - disclose experiments or research data. In the long run, the benefit of ELNs is the option to store and manage data in a standardized way and to enrich the data with (automatically generated) information such as metadata, identifiers and descriptors. For scientists, ELNs offer advantages such as faster research processes and a faster access to information. Selected benefits of the ELN Chemotion - an ELN that was designed for the discipline Chemistry - will be presented to show exemplarily the use of research data management tools. The ELN offers special features for chemical work and includes diverse functions that allow the use of the ELN also in other disciplines. Both, the chemistry specific as well as the generic and adaptable modules will be presented in brief. Chemotion ELN can be used in combination with the open access repository Chemotion. The disclosure of research data to the public is possible by a direct transfer of information from the ELN to the repository. The interoperable systems ELN and repository guarantee on the one hand an easy process for the disclosure of information and on the other hand the availability of comprehensive data including primary data and descriptions. The systems Chemotion ELN and Chemotion Repository are part of the strategy of the National Research Data Infrastructure for Chemistry (NFDI4Chem) in Germany. Dr. John Jolliffe from NFDI4Chem will present the strategy and measures of NFDI4Chem in brief.

 Note: An extended presentation about Chemotion ELN and the Chemotion Repository was held by Dr. John Jolliffe in the context of a HeFDI Data Talk on the 5th of May 2023.

 The three-day HeFDI Data Week enables researchers, teachers and everyone interested to get to know and try out topics and services of research data management.

title:  La concezione di mutamento sociale in Georg Simmel

Publisher: name: Roma TrE-Press
Year: 2016

description: Il contributo ricostruisce l’idea di mutamento sociale in Georg Simmel, ricavandola dalle sue opere, poiché egli non ha sviluppato una concezione compiuta al riguardo. La concezione di Mutamento sociale in Simmel ha solide basi teoriche, perché poggia sulla ‘filosofia della vita’ (Lebensphilosophie).
Il punto di partenza del ragionamento di Simmel è la vita (Leben). La vita per mantenersi avvia una serie di processi (es. riproduzione cel­lu­la­re), (Mehr Leben). A loro volta, tali processi per meglio adempiere alle esigenze della per­pe­tua­zione della vita stessa vengono organizzati (Mehr als Leben). Mehr als Leben consente alla vita di consolidarsi e proiettarsi nel futuro. Questo significa supe­rare l’equilibrio raggiunto in precedenza per meglio adattarsi alle esigenze del mondo. L’adatta­mento comporta aggiustamenti anche minimali e ciò significa che il cambiamento è continuo.
Dal punto di vista sociologico, per Simmel lo scambio tra gli esseri umani è la vita (Leben) della società. Lo scambio produce reciprocità (Wechsel­wirkung), vicendevoli influenze, una rete di relazioni (Mehr Leben).
Le inter­re­la­zioni umane si cristal­liz­zano in forme sociali, oggettive e sperso­na­liz­zate, cioè prescindo dalla contingenza e si elevano su di un piano sovra-individuale, più generale. Questo è il processo della Vergesellschaftung (Mehr als Leben. Nel pen­siero di Simmel le forme di (as)sociazione (Formen der Vergesellschaftung) si adattano nel corso del tempo ai cambiamenti cui incorre la vita, ossia al mutamento che compiono le convivenze umane. è un processo che forma la società.

Nitrogen cycling processes within stormwater control measures: A review and call for research

name: Thompson, S.P.
Publisher: name: Elsevier Ltd
Year: 2019

description: Stormwater control measures (SCMs) have the potential to mitigate negative effects of watershed development on hydrology and water quality. Stormwater regulations and scientific literature have assumed that SCMs are important sites for denitrification, the permanent removal of nitrogen, but this assumption has been informed mainly by short-term loading studies and measurements of potential rates of nitrogen cycling. Recent research concluded that SCM nitrogen removal can be dominated by plant and soil assimilation rather than by denitrification, and rates of nitrogen fixation can exceed rates of denitrification in SCM sediments, resulting in a net addition of nitrogen. Nitrogen cycling measurements from other human-impacted aquatic habitats have presented similar results, additionally suggesting that dissimilatory nitrate reduction to ammonium (DNRA) and algal uptake could be important processes for recycling nitrogen in SCMs. Future research should directly measure a suite of nitrogen cycling processes in SCMs and reveal controlling mechanisms of individual rate processes. There is ample opportunity for research on SCM nitrogen cycling, including investigations of seasonal variation, differences between climatic regions, and trade-offs between nitrogen removal and phosphorus removal. Understanding nitrogen dynamics within SCMs will inform more efficient SCM design and management that promotes denitrification to help mitigate negative effects of urban stormwater on downstream ecosystems.

description: We show that various duals that occur in optimization and
constraint satisfaction can be classified as inference duals, relaxation
duals, or both. We discuss linear programming, surrogate, Lagrangean,
superadditive, and constraint duals, as well as duals defined by resolution
and filtering algorithms. Inference duals give rise to nogood-based
search methods and sensitivity analysis, while relaxation duals provide
bounds. This analysis shows that duals may be more closely related than
they appear, as are surrogate and Lagrangean duals. It also reveals common
structure between solution methods, such as Benders decomposition
and Davis-Putnam-Loveland methods with clause learning. It provides a
framework for devising new duals and solution methods, such as generalizations
of mini-bucket elimination.

description: The S-matrix of the well-studied sinh-Gordon model possesses a remarkable strong/weak coupling duality $b \to 1/b$. Since there is no understanding nor evidence for such a duality based on the quantum action of the model, it should be questioned whether the properties of the model for $b>1$ are simply obtained by analytic continuation of the weak coupling regime $01$. Namely, we propose that in this region one needs to introduce a background charge $Q_\infty = b + 1/b -2$ which differs from the Liouville background charge by the shift of $-2$. We propose that in this regime the model has non-trivial massless renormalization group flows between two different conformal field theories. This is in contrast to the weak coupling regime which is a theory of a single massive particle. Evidence for our proposal comes from higher order beta functions. We show how our proposal correctly reproduces the freezing transitions in the multi-fractal exponents of a Dirac fermion in $2+1$ dimensions in a random magnetic field, which provides a strong check since such transitions have several detailed features. We also point out a connection between a semi-classical version of this transition and the so-called Manning condensation phenomena in polyelectrolyte physics.

description: The American economy currently produces a gross national product in excess of $1000 billion and is growing,at about 4% per year. The market is remarkable for what it manages to do. There are some areas where the market has failed, but by and large, few people would consider doing away with the market because of these failures. In 1977, when the full impact of the air pollution abatement laws are felt, we will be spending less than 1% of GNP to abate air pollution.
There are two courses of action when a market failure has been identified. The first is to leave it alone; we probably choose this alternative too rarely. The second is for the government to intervene by changing the legal and institutional structure which allowed the failure to occur or by creating a regulatory commission to manage the problem directly. We tend to underestimate the cost of government intervention in the market. The cost is very substantial and intervention should take place only for serious market failures.

description: We have measured the radial light profiles and global shapes of bars using two-dimensional 3.6 $μm $ image decompositions for 144 face-on barred galaxies from the Spitzer Survey of Stellar Structure in Galaxies (S4G). The bar surface brightness profile is correlated with the stellar mass and bulge-to-total (B/T) ratio of their host galaxies. Bars in massive and bulge-dominated galaxies (B/T$>$0.2) show a flat profile, while bars in less massive, disk-dominated galaxies (B/T$\sim$0) show an exponential, disk-like profile with a wider spread in the radial profile than in the bulge-dominated galaxies. The global two-dimensional shapes of bars, however, are rectangular/boxy, independent of the bulge or disk properties. We speculate that because bars are formed out of disk, bars initially have an exponential (disk-like) profile which evolves over time, trapping more stars into the boxy bar orbits. This leads bars to become stronger and have flatter profiles. The narrow spread of bar radial profiles in more massive disks suggests that these bars formed earlier (z$>$1), while the disk-like profiles and a larger spread in the radial profile in less massive systems imply a later and more gradual evolution, consistent with the cosmological evolution of bars inferred from observational studies. Therefore, we expect that the flatness of the bar profile can be used as a dynamical age indicator of the bar to measure the time elapsed since the bar formation. We argue that cosmic gas accretion is required to explain our results on bar profile and the presence of gas within the bar region.

description: Biotic interactions can structure ecological communities and influence ecosystem functioning. As ecosystem engineers and filter feeders, bivalves often have disproportionately large effects on ecosystem functioning. They also utilize numerous morphological and behavioral responses to reduce predation, which can include changes in their filtration rates. To test the response of Crassostrea virginica filtration rates to the presence of predators, juvenile and adult oysters were separately exposed to varying types of predation risk from Callinectes sapidus and Panopeus herbstii in outdoor mesocosms. Water column chlorophyll a concentrations and crab behavior were measured over the duration of the experiment. Predation risk had no effect on oyster reef drawdown of chlorophyll a, which suggests that this important ecosystem function of oyster reefs is not mediated by behaviorally induced predator effects. Therefore, efforts to model how oyster predators influence filtration rates and associated ecosystem services should focus primarily on the factors that influence oyster mortality rather than predator effects on oyster behavior.

description: PSR J2021+3651 is a 17 kyr old rotation powered pulsar detected in the radio, X-rays, and $γ$-rays. It powers a torus-like pulsar wind nebula with jets, dubbed the Dragonfly, which is very similar to that of the Vela pulsar. The Dragonfly is likely associated with the extended TeV source VER J2019+368 and extended radio emission. We conducted first deep optical observations with the GTC in the Sloan $r'$ band to search for optical counterparts of the pulsar and its nebula. No counterparts were detected down to $r'\gtrsim27.2$ and $\gtrsim24.8$ for the point-like pulsar and the compact X-ray nebula, respectively. We also reanalyzed Chandra archival X-ray data taking into account an interstellar extinction--distance relation, constructed by us for the Dragonfly line of sight using the red-clump stars as standard candles. This allowed us to constrain the distance to the pulsar, $D=1.8^{+1.7}_{-1.4}$ kpc at 90% confidence. It is much smaller than the dispersion measure distance of $\sim$12 kpc but compatible with a $γ$-ray "pseudo-distance" of 1 kpc. Based on that and the optical upper limits, we conclude that PSR J2021+3651, similar to the Vela pulsar, is a very inefficient nonthermal emitter in the optical and X-rays, while its $γ$-ray efficiency is consistent with an average efficiency for $γ$-pulsars of similar age. Our optical flux upper limit for the pulsar is consistent with the long-wavelength extrapolation of its X-ray spectrum while the nebula flux upper limit does not constrain the respective extrapolation.

ALMA Studies of Eruptive stars

Publisher: name: Zenodo

description: ALMA opened a new regime for studying episodic accretion in FU/EX Ori objects. Despite becoming highly popular in the last 15 years, we are still trying to understand episodic accretion, a process relevant to forming lowmass stars, binaries, and planets. Gravitational and thermal instabilities, disk fragmentation, forming planets, and stellar encounters are some of the different proposed triggering mechanisms for the outbursts. From recent ALMA and JVLA results, it is becoming clear that the highest resolutions are needed to image the very compact disks surrounding these objects and map the instabilities driving the activity. By imaging the inner regions, we can fit the temperatures and masses to estimate Toomre’s Q and check for the conditions to cause instabilities. Here we show our attempts to understand these disks with today’s ALMA capabilities. Still, very high-resolution imaging at lower frequencies (ALMA Band 1 and the ngVLA) will allow us to measure and correct for non-thermal contribution from the disk winds, which is crucial for estimating the disk temperatures in the optically thick bands. We also present ALMA images of FU Ori, the eruptive class prototype, for the first time, mapping its physical structure and kinematics from thousands of AU to a few AU scales.

description: We analyse a large sample of the Twitter activity developed around the social movement 'Occupy Wall Street' to study the complex interactions between the human communication activity and the semantic content of a discussion. We use a network approach based on the analysis of the bipartite graph @Users-#Hashtags and of its projections: the 'semantic network', whose nodes are hashtags, and the 'users interest network', whose nodes are users In the first instance, we find out that discussion topics (#hashtags) present a high heterogeneity, with the distinct role of the communication hubs where most the 'opinion traffic' passes through. In the second case, the self-organization process of users activity leads to the emergence of two classes of communicators: the 'professionals' and the 'amateurs'. Moreover the network presents a strong community structure, based on the differentiation of the semantic topics, and a high level of structural robustness when a certain set of topics are censored and/or accounts are removed. Analysing the characteristics the @Users-#Hashtags network we can distinguish three phases of the discussion about the movement. Each phase corresponds to specific moment of the movement: from declaration of intent, organisation and development and the final phase of political reactions. Each phase is characterised by the presence of specific #hashtags in the discussion. Keywords: Twitter, Network analysis

$β^-{\rm p}$ and $β^-α$ decay of the $^{11}$Be neutron halo ground state

description: Beta-delayed proton emission from the neutron halo ground state of $^{11}$Be raised much attention due to the unusually high decay rate. It was argued that this may be due to the existence of a resonance just above the proton decay threshold. In this Letter, we use the lenses of real-energy continuum shell model to describe several observables including the Gamow-Teller rates for the $β^-$-delayed $α$ and proton decays, and argue that, within our model, the large $β^-{\rm p}$ branching ratio cannot be reconciled with other data.

description: Particle-style token machines are a way to interpret proofs and programs, when the latter are written following the principles of linear logic. In this paper, we show that token machines also make sense when the programs at hand are those of a simple quantum lambda-calculus with implicit qubits. This, however, requires generalising the concept of a token machine to one in which more than one particle travel around the term at the same time. The presence of multiple tokens is intimately related to entanglement and allows us to give a simple operational semantics to the calculus, coherently with the principles of quantum computation.

Quality of life in pediatric asthma

description: Purpose of Project: Screening for HRQOL associated with asthma is important to ensure patients are receiving proper treatment and support. The Peds QLTM Asthma Module was utilized as a screening tool due to the supportive evidence the Peds QLTM Modules have and the several categories the tool covers (asthma symptoms, treatment, communication, worry). The goal of the assessment was to identify any trends based on a demographic questionnaire and Peds QLTM Asthma Module in a Pediatric Clinic’s Department of Pulmonology in Central New Jersey. Methodology: The proposed pilot project used a convenience sample of patients at a pediatric pulmonology practice with cross-sectional design along with the administration of the PedsQLTM Asthma Module tool and demographic questionnaire by Survey Monkey®. Screening was conducted on a total of 93 parents of patients between the ages of 5-18 years old to identify areas of reported decreased quality of life associated with asthma.Results: The lowest quality of life scores were in asthma symptomology, and the highest quality of life scores related to patients worrying about side effects of medications and whether they are working to decrease asthma exacerbations. Trends identified lower quality of life scores in the patient’s being responsible for their own medication in ages 8-18 years old. Implications for Practice: Implementing the PedsQL Asthma Module as a practice change may be adapted in pulmonology and primary practice locations with patients diagnosed with asthma. This can assist with improving overall patient care and daily family quality of life by identifying areas of lower quality of life based on asthma. With many of the low-scoring questions being related to asthma symptoms, outdoor activity tolerance, and remembrance of interventions, it was recommended for this practice to enforce education and the need to adhere to treatment.
