description: Understanding the stochastic dynamics of tracer particles in active fluids is important for identifying the physical properties of flow generating objects such as colloids, bacteria or algae. Here, we study both analytically and numerically the scattering of a tracer particle in different types of time-dependent, hydrodynamic flow fields. Specifically, we compare the tracer motion induced by an externally driven colloid with the one generated by various self-motile, multi-sphere swimmers. Our results suggest that force-free swimmers generically induce loop-shaped tracer trajectories. The specific topological structure of these loops is determined by the hydrodynamic properties of the microswimmer. Quantitative estimates for typical experimental conditions imply that the loops survive on average even if Brownian motion effects are taken into account.

description: El constante aumento del uso del internet, ha permitido que en los últimos años se incremente vertiginosamente el acceso al conocimiento científico. Revistas científicas que anteriormente solo estaban disponibles en su versión impresa, ahora se pueden consultar en línea, inclusive los primeros números de muchos años atrás. Sin embargo, no todas las publicaciones tienen esta posibilidad de consulta, ya que algunas de ellas mantienen un cobro para acceder a los artículos en sus versiones completas. Esta práctica contraviene el movimiento mundial que enmarca la denominada ciencia abierta, que para el caso de las revistas científicas permite el acceso ilimitado a los artículos publicados. Para colocar en contexto esta situación, se presentan algunos aspectos importantes que deben ser motivo de reflexión de nuestros lectores. Vidal et al. (2018) señalan que la “ciencia abierta” corresponde a la evolución hacia una ciencia más efectiva, accesible, transparente, interdisciplinaria y democrática en la medida que públicos más diversos participan y se ven beneficiados, todo esto posibilitado por las tecnologías de la información y las comunicaciones. Incluye una serie de componentes que le dan su connotación de apertura, como es la investigación abierta y reproducible, la evaluación por pares abierta, el acceso abierto a publicaciones y los datos abiertos, en particular de aquellos que se derivan de procesos financiados con recursos públicos y la investigación abierta.

description: We demonstrate single electron addition to different strands of a carbon nanotube rope. Anticrossings of anomalous conductance peaks occur in quantum transport measurements through the parallel quantum dots forming on the individual strands. We determine the magnitude and the sign of the hybridization as well as the Coulomb interaction between the carbon nanotube quantum dots, finding that the bonding states dominate the transport. In a magnetic field the hybridization is shown to be selectively suppressed due to spin effects.

Luís Souta - Bichos à Solta. 25 postais escritos por um pai à sua filha, lidos e apreciados por um amigo

description: Ao redigir este texto, não pretendo acrescentar qualquer novidade aos estudos realizados na área da fabulística, nem da epistolografia, nem tão pouco juntar mais uma peça ao conjunto de obras de arte existentes sobre os temas retratados. Bichos à solta é um conjunto de textos que se inscrevem na longa e prestigiada tradição epistolar. Não nos iludamos com as aparências e com os jogos ligeiros e graciosos que, em certa medida, para além da expressão de uma relação autêntica e apaixonada, também não deixam de se afirmar como estratégias discursivas e poéticas de um autor que sabe conciliar a sua sólida formação clássica com a sua contemporânea e comovente sensibilidade. No coração de um título, tão solto e aparentemente ingénuo, aninham-se vinte e cinco cartas profundamente pedagógicas. As cartas, tais como as de Séneca, o filósofo estóico cordovês que o Padre Manuel Antunes apelidou de “filósofo da condição humana”, não têm como destinatário uma figura retórica, um artifício meramente literário, mas sim um familiar intensamente próximo, que permite a troca de informações íntimas, quase sempre de índole filosófica, por vezes superficiais. A comunicação emotiva basta-se a si própria, tal como se satisfaz a comunicação poética. As cartas pontuam uma demanda muito subtil por uma espécie de Santo Graal donde irradiam as complexas e tão luminosas relações entre o amor paterno e as correspondências filiais. Nessa peregrinação opera-se um verdadeiro processo de iniciação que pretende transmitir os valores mais nobres da existência humana, consubstanciados nas mais sagradas regras de respeito pelo outro, pela natureza e por todas as suas criaturas. Conhecemos semelhante processo desde a sétima carta de Platão e dos vários volumes da correspondência de Cícero. Cada postal ostenta um título, que nos permite seguir o crescimento da destinatária, assim como as metamorfoses e o processo de maturação do emissor. O local de redação desenha um percurso mítico numa secreta geografia de aventuras e emoções que o emissor partilha com a filha, enquanto confidente e única companheira que, sem o acompanhar, não deixa de estar sempre presente, pela força do muito amar. As datas da redação de cada missiva são frequentemente sempre comemorativas, comemora-se a escrita, a vida, a liberdade, o ambiente, as artes e a paz. As que o mencionam relacionam-se sobretudo com as crianças, com a família, com a natureza e com os animais. É difícil não se render a tanta sedução, a um jogo tão envolvente de toca e foge. Jogar às escondidas com o passado e com o destino, com o tu e com o eu, com a água e com o fogo faz parte da arte das metamorfoses infantis, de golfinho a gato assanhado, de cão vadio a cavalo desenfreado.

description: Beam orientation optimization (BOO) is a key component in the process of IMRT treatment planning. It determines to what degree one can achieve a good treatment plan quality in the subsequent plan optimization process. In this paper, we have developed a BOO algorithm via adaptive l_1 minimization. Specifically, we introduce a sparsity energy function term into our model which contains weighting factors for each beam angle adaptively adjusted during the optimization process. Such an energy term favors small number of beam angles. By optimizing a total energy function containing a dosimetric term and the sparsity term, we are able to identify the unimportant beam angles and gradually remove them without largely sacrificing the dosimetric objective. In one typical prostate case, the convergence property of our algorithm, as well as the how the beam angles are selected during the optimization process, is demonstrated. Fluence map optimization (FMO) is then performed based on the optimized beam angles. The resulted plan quality is presented and found to be better than that obtained from unoptimized (equiangular) beam orientations. We have further systematically validated our algorithm in the contexts of 5-9 coplanar beams for 5 prostate cases and 1 head and neck case. For each case, the final FMO objective function value is used to compare the optimized beam orientations and the equiangular ones. It is found that, our BOO algorithm can lead to beam configurations which attain lower FMO objective function values than corresponding equiangular cases, indicating the effectiveness of our BOO algorithm.

description: AbstractViral infections, including hepatitis C, can cause secondary glomerular nephropathies. Studies suggest that hepatitis C virus infection (HCV+) is a risk factor for chronic kidney disease (CKD) but evidence of this relationship is lacking among Hispanics/Latinos. We examined the association between HCV+ and incident CKD in a prospective cohort of Hispanics/Latinos enrolled in the Hispanic Community Health Study/Study of Latinos. HCV+ was defined by detectable HCV antibodies with additional confirmation through HCV RNA or recombinant immunoblot assay testing. Incident CKD was defined by an estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2or sex-specific threshold for albuminuria measured during follow-up. We used Poisson regression to estimate incidence rate ratios (IRR) of CKD and changes in eGFR- or albuminuria-based risk stages, separately. We used linear regression to estimate associations with continuous, annualized changes in eGFR and albuminuria.Over a follow-up period of 5.9 years, 712 incident CKD events occurred among 10,430 participants. After adjustment for demographic characteristics and comorbidities, HCV+ was not associated with incident CKD, defined by eGFR and albuminuria thresholds (IRR 1.29, 95% Confidence Interval 0.61, 2.73). HCV+ was significantly associated with higher eGFR risk stages (IRR 2.39, 95% CI 1.47, 3.61) with most participants transitioning from stage G1 to G2. HCV+ was associated with a continuous, annualized eGFR decline of -0.69 mL/min/m2/year (95% CI -1.23, -0.16). This large, cohort study did not find evidence of a strong association between HCV+ and new-onset CKD among Hispanics/Latinos. HCV infection may not be associated with risk of CKD among Hispanics/Latinos, although treatment with direct-acting antivirals is recommended for all HCV+ individuals, including those with established CKD or end-stage kidney disease.

Persistent Rabi oscillations probed via low-frequency noise correlation

description: The qubit Rabi oscillations are known to be non-decaying (though with a fluctuating phase) if the qubit is continuously monitored in the weak-coupling regime. In this paper we propose an experiment to demonstrate these persistent Rabi oscillations via low-frequency noise correlation. The idea is to measure a qubit by two detectors, biased stroboscopically at the Rabi frequency. The low-frequency noise depends on the relative phase between the two combs of biasing pulses, with a strong increase of telegraph noise in both detectors for the in-phase or anti-phase combs. This happens because of self-synchronization between the persistent Rabi oscillations and measurement pulses. Almost perfect correlation of the noise in the two detectors for the in-phase regime and almost perfect anticorrelation for the anti-phase regime indicates a presence of synchronized persistent Rabi oscillations. The experiment can be realized with semiconductor or superconductor qubits.

description: Monte Carlo simulations are used to compute the centrality dependence of the odd moments of the initial eccentricity $ε_{n+1}$, relative to the even order (n) participant planes $Ψ^*_n$ in Au+Au collisions. The results obtained for two models of the eccentricity -- the Glauber and the factorized Kharzeev-Levin-Nardi (fKLN) models -- indicate magnitudes which are essentially zero. They suggest that a possible correlation between the orientations of the the odd and even participant planes ($Ψ^*_{n+1}$ and $Ψ^*_n$ respectively), do not have a significant influence on the calculated eccentricities. An experimental verification test for correlations between the orientations of the the odd and even participant planes is also proposed.

description: Climate change is causing many impacts on society that will only become even more amplified as the phenomenon progresses. One such impact is the prevalence of natural disasters, which increase in frequency and intensity due to the warming globe. In order to respond to disasters, we envision the development of interconnected AI-driven systems that detect damage and enable near-instantaneous pipelines for disaster relief. These technologies utilize computer vision to assess the severity of damage and aid in the timely and equitable allocation of resources. While currently AI models are being developed, the deployment process is complex, especially in the context of IoT.

Embedded protostellar disks around (sub-)solar stars. II. Disk masses, sizes, densities, temperatures and the planet formation perspective
Creators: name: Vorobyov, Eduard I.

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: We present basic properties of protostellar disks in the embedded phase of star formation (EPSF), which is difficult to probe observationally using available observational facilities. We use numerical hydrodynamics simulations of cloud core collapse and focus on disks formed around stars in the 0.03-1.0 Msun mass range. Our obtained disk masses scale near-linearly with the stellar mass. The mean and median disk masses in the Class 0 and I phases (M_{d,C0}^{mean}=0.12 Msun, M_{d,C0}^{mdn}=0.09 Msun and M_{d,CI}^{mean}=0.18 Msun, M_{d,CI}^{mdn}=0.15 Msun, respectively) are greater than those inferred from observations by (at least) a factor of 2--3. We demonstrate that this disagreement may (in part) be caused by the optically thick inner regions of protostellar disks, which do not contribute to millimeter dust flux. We find that disk masses and surface densities start to systematically exceed that of the minimum mass solar nebular for objects with stellar mass as low as M_st=0.05-0.1 Msun. Concurrently, disk radii start to grow beyond 100 AU, making gravitational fragmentation in the disk outer regions possible. Large disk masses, surface densities, and sizes suggest that giant planets may start forming as early as in the EPSF, either by means of core accretion (inner disk regions) or direct gravitational instability (outer disk regions), thus breaking a longstanding stereotype that the planet formation process begins in the Class II phase.

description: We present a close companion search around sixteen known early-L dwarfs using aperture masking interferometry with Palomar laser guide star adaptive optics. The use of aperture masking allows the detection of close binaries, corresponding to projected physical separations of 0.6-10.0 AU for the targets of our survey. This survey achieved median contrast limits of Delta_K ~ 2.3 for separations between 1.2 - 4 lambda/D, and Delta_K ~ 1.4 at (2/3)lambda/D. We present four candidate binaries detected with moderate to high confidence (90-98%). Two have projected physical separations less than 1.5 AU. This may indicate that tight-separation binaries contribute more significantly to the binary fraction than currently assumed, consistent with spectroscopic and photometric overluminosity studies. Ten targets of this survey have previously been observed with the Hubble Space Telescope as part of companion searches. We use the increased resolution of aperture masking to search for close or dim companions that would be obscured by full aperture imaging, finding two candidate binaries. This survey is the first application of aperture masking with laser guide star adaptive optics at Palomar. Several new techniques for the analysis of aperture masking data in the low signal to noise regime are explored.

description: In lowest unique bid auctions, $N$ players bid for an item. The winner is whoever places the \emph{lowest} bid, provided that it is also unique. We use a grand canonical approach to derive an analytical expression for the equilibrium distribution of strategies. We then study the properties of the solution as a function of the mean number of players, and compare them with a large dataset of internet auctions. The theory agrees with the data with striking accuracy for small population size $N$, while for larger $N$ a qualitatively different distribution is observed. We interpret this result as the emergence of two different regimes, one in which adaptation is feasible and one in which it is not. Our results question the actual possibility of a large population to adapt and find the optimal strategy when participating in a collective game.

Multiculturalismo liberal: fim do caminho. E agora?
Creators: name: Cardoso, Carlos Manuel
Publisher: name: Medi@ções
Year: 2017

description: Nos últimos anos, em diversos países ocidentais, a multiculturalidade tem estado cada vez mais afastada dos discursos políticos e, em alguns casos, é neles hostilizada através de mensagens de teor xenofóbico. Factos como estes são reveladores de um processo de fragilização das políticas para a promoção da igualdade cultural, étnica e racial. Este recuo multicultural ocorre em contradição com algumas evidências: a diversidade é uma característica definitiva, crescente e indispensável nas nossas sociedades; as condições dos imigrantes e dos refugiados, a par com situações de xenofobia e racismo, têm vindo a agravar-se. O recuo do compromisso político-institucional face às condições daqueles grupos e de outras minorias étnico-culturais, é o pressuposto deste artigo. Nele, procuramos enumerar, reflectir e discutir alguns aspectos geradores da actual situação das políticas multiculturais. Não se trata de defender a continuidade do multiculturalismo liberal como o temos conhecido, mas sim a necessidade de reconfigurar e relançar novos compromissos institucionais para a inclusão cultural, étnica e racial. Para isso, adquirem particular importância os diferentes, mas convergentes, contributos da investigação, da educação, dos movimentos sociais em favor dos direitos humanos e dos media.

Key insights in disseminating Multidimensional Rietveld Refinement

Publisher: name: Zenodo
Year: 2025

description: Our group specializes in the development of neutron powder diffraction methods, primarily utilizing the neutron time-of-flight diffractometer POWTEX, which was developed in collaboration with Forschungszentrum Jülich at FRM-II in Garching. As part of the DAPHNE project, we are expanding these methodologies to enhance their applications, with a strong emphasis on sustainability.

We are actively engaged in researching multidimensional data reduction and Rietveld refinement techniques that are applicable not only to POWTEX but also to large-area detector TOF diffractometers such as POWGEN and SNAP at SNS, ORNL in the USA, as well as future TOF diffractometers at ESS. Recent advancements have allowed for efficient multidimensional data reduction using the Mantid software. Furthermore, we have incorporated multidimensional refinement routines into a customized version of GSAS-II, which is currently undergoing refactoring and testing with real samples.

Our successful trials have already demonstrated the application of these methods on the POWTEX detector operated at POWGEN (SNS, ORNL), as published [1]. However, to extend these methodologies to other instruments effectively, the availability of instrument-specific information is crucial; unfortunately, this information is often not readily provided.

To address this issue, we propose creating a nexus file that serves as a centralized repository for all metadata related to an experiment—including essential instrument-specific details. This nexus file could also encompass information about any related files necessary during data reduction and versioning of algorithms used for this process. By ensuring that refinement software is properly adjusted, separate files for instrument parameters would become superfluous, thereby streamlining the analysis of measurement data.

Building on these concepts, we have developed a sample nexus file that incorporates some of the aforementioned features. It contains fundamental instrument parameters along with links to related files. These links can then be utilized during data reduction in Mantid through a slightly modified version of our algorithm PowderReduceP2D. Additionally, this algorithm automatically generates instrument parameter files that would otherwise need to be downloaded separately.

This integrated approach enhances both efficiency and accessibility in neutron powder diffraction research while supporting our commitment to sustainability and broadening the applicability of our methods across various instruments.
Optimal detection of losses by thermal probes

description: We consider the discrimination of lossy bosonic channels and focus to the case when one of the values for the loss parameter is zero, i.e., we address the detection of a possible loss against the alternative hypothesis of an ideal lossless channel. This discrimination is performed by inputting one-mode or two-mode squeezed thermal states with fixed total energy. By optimizing over this class of states, we find that the optimal inputs are pure, thus corresponding to single- and two-mode squeezed vacuum states. In particular, we show that for any value of the damping rate smaller than a critical value there is a threshold on the energy that makes the two-mode squeezed vacuum state more convenient than the corresponding single-mode state, whereas for damping larger than this critical value two-mode squeezed vacua are always better. We then consider the discrimination in realistic conditions, where it is unlikely to have pure squeezing. Thus by fixing both input energy and squeezing, we show that two-mode squeezed thermal states are always better than their single- mode counterpart when all the thermal photons are directed into the dissipative channel. Besides, this result also holds approximately for unbalanced distribution of the thermal photons. Finally, we also investigate the role of correlations in the improvement of detection. For fixed input squeezing (single-mode or two-mode), we find that the reduction of the quantum Chernoff bound is a monotone function of the two-mode entanglement as well as the quantum mutual information and the quantum discord. We thus verify that employing squeezing in the form of correlations (quantum or classical) is always a resource for loss detection whenever squeezed thermal states are taken as input.

description: Let $K$ be a finite extension of $\Q_p$, let $L/K$ be a finite abelian Galois extension of odd degree and let $\bo_L$ be the valuation ring of $L$. We define $A_{L/K}$ to be the unique fractional $\bo_L$-ideal with square equal to the inverse different of $L/K$. For $p$ an odd prime and $L/\Q_p$ contained in certain cyclotomic extensions, Erez has described integral normal bases for $A_{L/\Q_p}$ that are self-dual with respect to the trace form. Assuming $K/\Q_p$ to be unramified we generate odd abelian weakly ramified extensions of $K$ using Lubin-Tate formal groups. We then use Dwork's exponential power series to explicitly construct self-dual integral normal bases for the square-root of the inverse different in these extensions.

Applying college choice theory to student selection of a pharmacy school : a qualitative study

Publisher: name: The University of Texas at Austin
Year: 2014
Subjects: College choice

description: The decision to go to college may be one of the most important choices a person makes in his or her lifetime. Students considering higher education following completion of high school have come to the realization that the additional education may influence career choices, potential earnings, and professional and personal satisfaction. Students considering a college education undergo different phases in making the decision of an institution to attend. Depending on the individual, this process may have occurred over many years and/or during the time the student is in high school. The goal of this study is to determine if the pharmacy college choice process used by prospective pharmacy students followed other college choice models (including Hossler and Gallagher’s (1987) three-phase model) and identifying the primary and secondary factors that influence final choice. A qualitative methodology is employed to understand the phenomenon of Pharmacy College Choice (PCC) from the perspective of students who had just gone through this experience. This study examines the college choice process at two Texas institutions. This research seeks to understand the lived experience of students selecting a college of pharmacy by inquiring 1) what is the college decision-making process for pharmacy students, 2) how do students select a school of pharmacy to attend, 3) what factors influence students’ choice of a pharmacy program to attend at different types of institutions.
Homogeneous Lorentzian manifolds of a semisimple group

Year: 2011
Subjects: subject: Differential Geometry (math.DG)
subject: FOS: Mathematics

description: We describe the structure of $d$-dimensional homogeneous Lorentzian $G$-manifolds $M=G/H$ of a semisimple Lie group $G$. Due to a result by N. Kowalsky, it is sufficient to consider the case when the group $G$ acts properly, that is the stabilizer $H$ is compact. Then any homogeneous space $G/\bar H$ with a smaller group $\bar H \subset H$ admits an invariant Lorentzian metric. A homogeneous manifold $G/H$ with a connected compact stabilizer $H$ is called a minimal admissible manifold if it admits an invariant Lorentzian metric, but no homogeneous $G$-manifold $G/\tilde H$ with a larger connected compact stabilizer $\tilde H \supset H$ admits such a metric. We give a description of minimal homogeneous Lorentzian $n$-dimensional $G$-manifolds $M = G/H$ of a simple (compact or noncompact) Lie group $G$. For $n \leq 11$, we obtain a list of all such manifolds $M$ and describe invariant Lorentzian metrics on $M$.

Consistent multiple sequence decoding
Creators: name: Xu, Bicheng
Publisher: name: University of British Columbia
Year: 2020

description: Sequence decoding is one of the core components of most visual-lingual models. However, typical neural decoders when faced with decoding multiple, possibly correlated, sequences of tokens resort to simple independent decoding schemes. In this work, we introduce a consistent multiple sequence decoding architecture, which, while relatively simple, is general and allows for consistent and simultaneous decoding of an arbitrary number of sequences. Our formulation utilizes a consistency fusion mechanism, implemented using message passing in a Graph Neural Network (GNN), to aggregate context from related decoders. This context is then utilized as a secondary input, in addition to previously generated output, to make a prediction at a given step of decoding. Self-attention, in the GNN, is used to modulate the fusion mechanism locally at each node and each step in the decoding process. We show the efficacy of our consistent multiple sequence decoder on the task of dense relational captioning and illustrate state-of-the-art performance (improvement of 5.2% in mAP) on the task. More importantly, we illustrate that the decoded sentences, for the same regions, are more consistent (improvement of 9.5% in consistency score), while across images and regions maintain diversity.
On some algebraic properties of CM-types of CM-fields and their reflexes
Creators: name: Oishi-Tomiyasu, Ryoko
Publisher: name: arXiv
Year: 2010
Subjects: subject: Number Theory (math.NT)
subject: FOS: Mathematics

description: The purpose of this paper is to show that the reflex fields of a given CM-field is equipped with a certain combinatorial structure that has not been exploited yet. We prove three theorems using this structure; the first theorem is on the abelian extension generated by the moduli and the b-torsion points of abelian varieties of CM-type, for any natural number b. It is a generalization of the result by Wei on the abelian extension obtained by the moduli and all the torsion points. The second theorem gives a character identity of the Artin L-function of a CM-field K and the reflex fields of K. The character identity pointed out by Shimura follows from this. The third theorem states that some Pfister form is isomorphic to the orthogonal sum of Tr(\bar{a}a) (\bar{a} is the complex conjugation of a) defined on a direct sum of reflex fields. This result suggests that the theory of complex multiplication on abelian varieties has a relationship with the multiplicative forms in higher dimension.
