description: Esta minha conferência encerra um ciclo de conferências e debates organizados pela BAD na livraria Barata sobre Ética Profissional de Profissionais de Informação. Em todas as outras estiveram quatro pessoas a falar, nesta estarei eu sozinha. Espero que tenham a paciência de me ouvir e de questionarem todas as minhas afirmações para que, em conjunto, possamos reflectir sobre este tema.Esta conferência tem quatro partes:- Uma Introdução Geral em que apresento sumariamente a distinção entre ética e moral e relaciono o Código de Ética para os profissionais de informação em Portugal com a Declaração Universal dos Direitos Humanos.- Depois apresento o conceito de Privacidade. A clarificação de um conceito ajuda-nos a perceber melhor porque é que o devemos defender. Relaciono o conceito com as situações mais comuns da prática profissional e baseio o compromisso de respeito para com a Privacidade que assumimos no nosso código de ética com o artigo 12º da DUDH.- Em seguida, explico o que é Liberdade Intelectual, fundamento-a no artigo 19º da DUDH e explicito o seu conceito. Dou ao direito à livre expressão e à liberdade de acesso à informação a sua fundamentação mais humanista.- Termino apresentando o Código de Ética para os Profissionais de Informação em Portugal, digo o que ele não é, exorto à sua aplicação.Segue-se um debate, que está a vosso cargo. Se por acaso tiverem alguma dúvida sobre o que afirmei perguntem. Se tiverem algum caso bicudo que se relacione com estes dois temas: Privacidade e Liberdade Intelectual, por favor exponham-no. Procuraremos que o debate seja animado.

description: This research was conducted to measure the phenotypic performance of Kambro crossbreeds of Pelung Blirik Hitam and Broiler Cobb 500. Based on Body Weight (BT) measurement, Kambro population (n = 17) has an average BT of 1,244.14(..)453.82 grams significant (p <0.01) to F1 Pelung (n = 7) with an average BT of 602.88(..)79.93 grams in 8 weeks period with ad libitum diet of standard feed. Phenotypic performance of Kambro significant to F1 Pelung based on the measurement of linear bodyweight parameter, vitality parameter, PPa-PBe parameter, and phenotype parameter. Kambro has the phenotype combination of parental generation based on the phenotype parameter. PPa parameter was suitable BT estimation model based on non-linear quadratic regression (r = 0.956) with formula 1.84E3(..)3.54E2*x+31.73*x2. Difference between chicken group (p<0.014) was significant to BT and interaction between the group and linear bodyweight parameter was not significant based on Analysis of Covariance. The mortality rate of Kambro was lower than F1 Pelung with the absent of vaccination in a semi-intensive rearing system. As the size of the hybrids population was limited, research findings must be validated with a larger population size of hybrids.

subject: soybean cake and meal

description: Total use of soybean meal in Denmark is projected to increase to 756,000 tons in 1980, compared to a base period (1969) estimate of 468,000 tons. Much of the increase is expected in the milk and pork sectors, although consumption is also projected to increase in the beef, poultry meat, and egg sectors. These projections are based on applying feed conversion rates from previous studies and estimates of soybean meal in concentrates to projections of production of livestock products. Alternative projections were undertaken assuming an improvement in feed conversion rates for concentrates and an increase in the percentage of nongrain feeds in rations. Under these assumptions total consumption of soybean meal is projected to reach 814,000 tons in 1980, 8 percent above the original projection. The projected rise in livestock production reflects the effect of EC membership, which is expected to increase net returns to producers in the long run and boost Danish agricultural exports. Danish agricultural exports had been adversely affected by the Common Agricultural Policy. Total imports of all vegetable oilcakes and meal have risen significantly in recent years, reflecting increased use of oilcakes and meal in feed rations. The United States has been the major supplier of soybeans to Denmark and in 1973 supplied over 90 percent of the 388,000-ton market.

description: A model for the generation of fractal growth networks in Euclidean spaces of arbitrary dimension is presented. These networks are considered as the spatial support of reaction-diffusion and pattern formation processes. The local dynamics at the nodes of a fractal growth network is given by a nonlinear map, giving raise to a coupled map system. The coupling is described by a matrix whose eigenvectors constitute a basis on which spatial patterns on fractal growth networks can be expressed by linear combination. The spectrum of eigenvalues the coupling matrix exhibits a nonuniform distribution that is reflected in the presence of gaps or niches in the boundaries of stability of the synchronized states on the space of parameters of the system. These gaps allow for the selection of specific spatial patterns by appropriately varying the parameters of the system.

description: This paper aims to put constraints on the parameters of the Scalar Field Dark Matter (SFDM) model, when dark matter is described by a free real scalar field filling the whole Universe, plus a cosmological constant term. By using a compilation of 51 $H(z)$ data and 1048 Supernovae data from Panteon, a lower limit for the mass of the scalar field was obtained, $m \geq 5.1\times 10^{-34} $eV and $H_0=69.5^{+2.0}_{-2.1}\text{ km s}^{-1}\text{Mpc}^{-1}$. Also, the present dark matter density parameter was obtained as $Ω_ϕ= 0.230^{+0.033}_{-0.031}$ at $2σ$ confidence level. The results are in good agreement to standard model of cosmology, showing that SFDM model is viable in describing the dark matter content of the universe.

description: The Spitzer Space Telescope, NASA's Great Observatory for infrared astronomy, was launched 2003 August 25 and is returning excellent scientific data from its Earth-trailing solar orbit. Spitzer combines the intrinsic sensitivity achievable with a cryogenic telescope in space with the great imaging and spectroscopic power of modern detector arrays to provide the user community with huge gains in capability for exploration of the cosmos in the infrared. The observatory systems are largely performing as expected and the projected cryogenic lifetime is in excess of 5 years. This paper summarizes the on-orbit scientific, technical and operational performance of Spitzer. Subsequent papers in this special issue describe the Spitzer instruments in detail and highlight many of the exciting scientific results obtained during the first six months of the Spitzer mission.

description: The LOCKSS program has developed and deployed in a world-wide test a system for preserving access to academic journals published on the Web. The fundamental problem for any digital preservation system is that it must be affordable for the long term. To reduce the cost of ownership, the LOCKSS system uses generic PC hardware, open source software, and peer-to-peer technology. It is packaged as a ``network appliance'', a single-function box that can be connected to the Internet, configured and left alone to do its job with minimal monitoring or administration. The first version of this system was based on a Linux boot floppy. After three years of testing it was replaced by a second version, based on OpenBSD and booting from CD-ROM. We focus in this paper on the design, implementation and deployment of a network appliance based on an open source operating system. We provide an overview of the LOCKSS application and describe the experience of deploying and supporting its first version. We list the requirements we took from this to drive the design of the second version, describe how we satisfied them in the OpenBSD environment, and report on the initial

description: The objective is to establish a method in providing emergency potable water to the University Endowment Lands (UEL) by accessing groundwater from the Quadra Sand Layer.The UEL includes the University of British Columbia (UBC) campus and the population is estimated to be 55,000 people per day. Water is currently supplied by Metro Vancouver through two water mains. If these water mains become unusable due to a natural disaster, UBC would be unable to provide clean potable water to residents. Key constraints considered are total water demand, water quality, water volume, and method of distribution. The desired outcome of this project is to prepare UBC to be self-sufficient in an emergency situation. Team 20 created a five-day demand cycle using the given data. The per capita and UBC hospital demand were established as approximately 10 L/Cap-Day and 190k L/Day, respectively. The total required emergency potable water for this project is approximately 3.7 million liters over five days. These figures are the minimum potable water required as per the Government of Canada’s Drinking Water Quantity Guideline. In addition, a groundwater feasibility study estimated 4.9 million liters of available water via ground infiltration within the UEL. The final design was established by analyzing and segmenting the UBC population by location. Team 20 chose six development locations on the UEL using population density. At each location, a groundwater well and pumphouse will be constructed. In an emergency, UBC personnel will shut off compromised sections of water distribution infrastructure and the pumphouse will connect to and pressurize the existing and intact UBC water distribution infrastructure forming a “closed loop” network. In the event that disaster damages the entire water distribution network, each pumphouse has the ability to serve as a manual water distribution-site. The estimated cost of this project, including a 5% consulting fee, a 20% contingency fund, and a 12% tax rate, is $1,486,300 CAD.

Using this lemma we show how known results about multidimensional three distance theorem can be deduced from certain known results dealing with the best Diophantine approximations. Also we obtain some new results about liminf version of the problem. Beside this, we discuss the inverse problem: how results about multidimensional three distance theorem can be applied to study best Diophantine approximations.

Neste percurso, há questões para as quais não encontrámos ainda uma resposta consensual – por exemplo, continuamos a necessitar de operar com um conceito de documento, em tempos transparente e que a ninguém suscitava dúvidas, ou essa é uma entidade ultrapassada, a banir no universo digital? Ou, que papel podemos reivindicar numa abordagem ao conhecimento como entidade susceptível de ser gerida, nomeadamente, enquanto capital fundamental de uma organização?Convidámos um conjunto de pessoas, da área BAD e de áreas afins – porque é nosso objectivo também facilitar a comunicação interdisciplinar – a dar a sua perspectiva de abordagem a estas problemáticas. Infelizmente, nem todas acabaram por concretizar a sua reflexão em tempo útil à inclusão do trabalho neste número dos Cadernos BAD mas, ainda assim, cremos que o resultado final é susceptível de insuflar ânimo a um debate que nos parece necessário.

Electromagnetic mass-models in general relativity reexamined
Creators: name: de Leon, J. Ponce
Publisher: name: arXiv
Year: 2003
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: The problem of constructing a model of an extended charged particle within the context of general relativity has a long and distinguished history. The distinctive feature of these models is that, in some way or another, they require the presence of negative mass in order to maintain stability against Coulomb's repulsion. Typically, the particle contains a core of $negative$ mass surrounded by a positive-mass outer layer, which emerges from the Reissner-Nordström field. In this work we show how the Einstein-Maxwell field equations can be used to construct an extended model where the mass is positive everywhere. This requires the principal pressures to be unequal inside the particle. The model is obtained by setting the "effective" matter density, rather than the rest matter density, equal to zero. The Schwarzschild mass of the particle arises from the electrical and gravitational field (Weyl tensor) energy. The model satisfies the energy conditions of Hawking and Ellis. A particular solution that illustrates the results is presented.

description: In this paper, we develop a framework to obtain graph abstractions for decision-making by an agent where the abstractions emerge as a function of the agent's limited computational resources. We discuss the connection of the proposed approach with information-theoretic signal compression, and formulate a novel optimization problem to obtain tree-based abstractions as a function of the agent's computational resources. The structural properties of the new problem are discussed in detail, and two algorithmic approaches are proposed to obtain solutions to this optimization problem. We discuss the quality of, and prove relationships between, solutions obtained by the two proposed algorithms. The framework is demonstrated to generate a hierarchy of abstractions for a non-trivial environment.

description: In the present work, we investigate the production of $P-$wave charmed or charmed-strange mesons in the pion or kaon induced reactions on a proton target. The total cross sections as well as the differential cross sections depending on the scattering angle are evaluated in an effective Lagrangian approach. Our estimations indicate that magnitude of the cross sections strongly depends on the model parameter but such dependence can be almost completely canceled for the cross section ratios. These model independent ratios can be taken as a good criterion of the validity of heavy quark limit in the charmed region, which is helpful to understand $P$-wave charmed and charmed-strange mesons.

Ultrahigh-energy neutrinos as a probe of espresso-shear acceleration in jets of Centaurus A

description: It has been suggested that Centaurus A (Cen A) could make a contribution to the observed ultrahigh-energy cosmic-ray (UHECR) flux. We calculate the flux of astrophysical neutrinos produced by UHECRs accelerated in the jet of Cen A, a close-by jetted active galactic nucleus. We use a bottom-up approach, in which we follow the energization of protons and heavier elements in a magnetohydrodynamic simulation of a relativistic jet with proper parameters of Cen A, also accounting for attenuation losses based on the observed photon fields. We compare the expected neutrino flux with the sensitivity of current and planned neutrino detectors. We find that the detection of $\sim 10^{17}$-$10^{18}$ eV neutrinos from Cen A would require ultimate neutrino detectors that reach a point source sensitivity of $\sim {\rm a~few}\times10^{-13}~{\rm erg}~{\rm cm}^{-2}~{\rm s}^{-1}$. Successful detection, though challenging, would be useful in constraining the Cen A contribution to the UHECRs.

B-factory Signals for a Warped Extra Dimension

Year: 2004
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We study predictions for B-physics in a class of models, recently introduced, with a non-supersymmetric warped extra dimension. In these models few ($\sim 3$) TeV Kaluza-Klein masses are consistent with electroweak data due to bulk custodial symmetry. Furthermore, there is an analog of GIM mechanism which is violated by the heavy top quark (just as in SM) leading to striking signals at $B$-factories:(i) New Physics (NP) contributions to $ΔF= 2$ transitions are comparable to SM. This implies that, within this NP framework, the success of SM unitarity triangle fit is a ``coincidence'' Thus, clean extractions of unitarity angles via e.g. $B \to ππ,ρπ, ρρ, DK$ are likely to be affected, in addition to O(1) deviation from SM prediction in $B_s$ mixing. (ii) O(1) deviation from SM predictions for $B \to X_s l^+ l^-$ in rate as well as in forward-backward and direct CP asymmetry. (iii) Large mixing-induced CP asymmetry in radiative B decays, wherein the SM unamibgously predicts very small asymmetries. Also with KK masses 3 TeV or less, and with anarchic Yukawa masses, contributions to electric dipole moments of the neutron are roughly 20 times larger than the current experimental bound so that this framework has a "CP problem".
description: On further consideration, we found that our framework does have a "CP problem" in that though contributions to neutron's electric dipole moment from CKM-like phases vanish at the one-loop level, sizeable contributions are induced by Majorana-like phases.

description: The interactions of different particle species with the foamy space-time fluctuations expected in quantum gravity theories may not be universal, in which case different types of energetic particles may violate Lorentz invariance by varying amounts, violating the equivalence principle. We illustrate this possibility in two different models of space-time foam based on D-particle fluctuations in either flat Minkowski space or a stack of intersecting D-branes. Both models suggest that Lorentz invariance could be violated for energetic particles that do not carry conserved charges, such as photons, whereas charged particles such electrons would propagate in a Lorentz-inavariant way. The D-brane model further suggests that gluon propagation might violate Lorentz invariance, but not neutrinos. We argue that these conclusions hold at both the tree (lowest-genus) and loop (higher-genus) levels, and discuss their implications for the phenomenology of quantum gravity.

description: Aim: In the past, observations of protostellar shocks have been able to set constraints on the formation route of formamide (NH2CHO), exploiting its observed spatial distribution and comparison with astrochemical model predictions. In this work, we follow the same strategy to study the case of acetaldehyde (CH3CHO). Method: To this end, we used the data obtained with the IRAM-NOEMA interferometer in the framework of the Large Program SOLIS to image the B0 and B1 shocks along the L1157 blueshifted outflow in methanol (CH3OH) and acetaldehyde line emission. Results: We imaged six CH3OH and eight CH3CHO lines which cover upper level energies up to 30 K. Both species trace the B0 molecular cavity as well as the northern B1 portion, i.e. the regions where the youngest shocks (1000 yr) occurred. The CH$_3$OH and CH$_3$CHO emission peaks towards the B1b clump, where we measured the following column densities and relative abundances: 1.3 x 10^16 cm-2 and 6.5 x 10-6 (methanol), and 7 x 10^13 cm-2 and 3.5 x 10-8 (acetaldehyde). We carried out a non-LTE LVG analysis of the observed CH3OH line: the average kinetic temperature and density of the emitting gas are Tkin = 90 K and nH2 = 4 x 10^5 cm-3, respectively. The CH3OH and CH3CHO abundance ratio towards B1b is 190, varying by less than a factor 3 throughout the whole B0-B1 structure. Conclusions: The comparison of astrochemical model predictions with the observed methanol and acetaldehyde spatial distribution does not allow to distinguish whether acetaldehyde is formed on the grain mantles or rather on the gas-phase, as its gas-phase formation, dominated by the reaction of ethyl radical (CH3CH2) with atomic oxygen, is very fast. Observations of acetaldehyde in younger shocks, e.g. 10^2 yr old, or/and of the ethyl radical, whose frequencies are not presently available, are necessary to settle the issue.

description: Impurities and random disorder are known to affect topological superconducting phases and their Majorana zero modes (MZMs). In particular, it is a common assumption that disorder negatively influences the braiding dynamics of MZMs. Recently, it was shown, however, that random disorder can also stabilize or even increase topological phases. Here, we investigate quantitatively how a single impurity can lead to braiding errors. We show that the impurity increases, in most scenarios, the dynamical hybridization of the MZMs, reducing the braiding performance. In addition, we show how random disorder, i.e., impurities on all lattice sites but with different strengths, affects braiding. As for the static case, we observe a window of opportunity where random disorder decreases the average energy of a braid, and thus improves braiding outcomes. This window of opportunity is, however, limited due to an increase of diabatic effects in the presence of disorder. Nevertheless and contrary to physical intuition, disorder can in certain situations be beneficial and improve braiding outcomes.

description: Digital Embedded Devices of next-generation safety-critical industrial automation systems require high levels of survivability and resilience against the hardware and software failure. One of the concepts for achieving this requirement is the design of resilient and survivable digital embedded systems. In the last two decades, development of self-healing digital systems based on molecular and cellular biology have received attention for the design of robust digital systems. However, many of these approaches have not been architected from the outset with safety in mind, nor have they been targeted for the applications of automation community where a significant need exists. This paper presents a new self-healing hardware architecture, inspired from the way nature responds, defends and heals: the stem cells in the immune system of living organisms, the life cycle of the living cell, and the pathway from Deoxyribonucleic acid (DNA) to protein. The proposed architecture is integrating cellular-based biological concepts, traditional fault tolerance techniques, and operational schematics for the international standard IEC 61131-3 to facilitate adoption in the automation industry and safety-critical applications. To date, two industrial applications have been mapped on the proposed architecture, which are capable of tolerating a significant number of faults that can stem from harsh environmental changes and external disturbances and we believe the nexus of its concepts can positively impact the next generation of critical systems in the automation industry

description: Nem sempre nos lembramos de que a imprensa não começou com Gutenberg: no Extremo-Oriente, as invenções do papel, dos blocos de impressão e dos tipos móveis foram etapas importantes de uma outra história da impressão e dos livros. Uma história que não só começou séculos antes da nossa como ainda continua. Em oficinas artesanais, por toda a China, ainda hoje se produzem alguns milhões de xilografias por ano: gravuras de Ano Novo (nianhua), amuletos (fu) e papéis para queimar aos deuses e aos mortos (zhima). Estas xilografias populares inserem-se num campo particular da cultura chinesa a que chamo o mundo do hua por oposição ao mundo do shu, aquele mundo da cultura erudita a que nós mais facilmente chamamos chinesa.

description: The psychologist Anne Treisman dedicated her career to the study of attention and perception, a central concern of cognitive science. While still a graduate student, she modified and reformulated the leading theory of auditory attention. Her discoveries and insights into the role of visual attention in the perception of objects, to which she devoted her subsequent decades of research, have had a lasting influence, not only in experimental psychology but also in vision research, neuroscience and artificial intelligence. In a period of rising interest in the brain, her foundational theories inspired thousands of experiments in her own field and others, and the originality and precision of her experimental design confirmed the continued relevance of behavioural research to the scientific enterprise. Treisman's accomplishments were recognized by the National Academy of Sciences in the USA in 1994 and by the American Academy of Arts and Sciences in 1995. In 1996, she became the first psychologist to win the Golden Brain Award. She received the University of Louisville Grawemeyer Award in Psychology in 2009, and was awarded the National Medal of Science by President Barack Obama at a White House ceremony in 2013.

description: The increasing availability of data has popularized risk estimation models in many industries, especially healthcare. However, properly utilizing these models for accurate diagnosis decisions remains challenging. Our research aims to determine when a risk estimation model provides sufficient evidence to make a positive or negative diagnosis, or if the model is inconclusive. We formulate the Two-Threshold Problem (TTP) as a stochastic program which maximizes sensitivity and specificity while constraining false-positive and false-negative rates. We characterize the optimal solutions to TTP as either two-threshold or one-threshold and show that its optimal solution can be derived from a related linear program (TTP*). We also derive utility-based and multi-class classification frameworks for which our analytical results apply. We solve TTP* using data-driven methods: quantile estimation (TTP*-Q) and distributionally robust optimization (TTP*-DR). Through simulation, we characterize the feasibility, optimality, and computational burden of TTP*-Q and TTP*-DR and compare TTP*-Q to an optimized single threshold. Finally, we apply TTP* to concussion assessment data and find that it achieves greater accuracy at lower misclassification rates compared with traditional approaches. This data-driven framework can provide valuable decision support to clinicians by identifying “easy” cases which can be diagnosed immediately and “hard” cases which may require further evaluation before diagnosing.

description: Molecular dynamics (MD) simulations have been carried out to investigate the slip of fluid in the lid driven cavity flow where the no-slip boundary condition causes unphysical stress divergence. The MD results not only show the existence of fluid slip but also verify the validity of the Navier slip boundary condition. To better understand the fluid slip in this problem, a continuum hydrodynamic model has been formulated based upon the MD verification of the Navier boundary condition and the Newtonian stress. Our model has no adjustable parameter because all the material parameters (density, viscosity, and slip length) are directly determined from MD simulations. Steady-state velocity fields from continuum calculations are in quantitative agreement with those from MD simulations, from the molecular-scale structure to the global flow. The main discovery is as follows. In the immediate vicinity of the corners where moving and fixed solid surfaces intersect, there is a core partial-slip region where the slippage is large at the moving solid surface and decays away from the intersection quickly. In particular, the structure of this core region is nearly independent of the system size. On the other hand, for sufficiently large system, an additional partial-slip region appears where the slippage varies as $1/r$ with $r$ denoting the distance from the corner along the moving solid surface. The existence of this wide power-law region is in accordance with the asymptotic $1/r$ variation of stress and the Navier boundary condition.

description: Starting with an experimentally observed networks of actin bundles, we model their network structure in terms of edges and nodes. We then compute and discuss the main electrical parameters, considering the bundles as electrical wires. A set of equations describing the network is solved with several initial conditions. Input voltages, that can be considered as information bits, are applied in a set of points and output voltages are computed in another set of positions. We consider both an idealized situation, where point-like electrodes can be inserted in any points of the bundles and a more realistic one, where electrodes lay on a surface and have typical dimensions available in the industry. We find that in both cases such a system can implement the main logical gates and a finite state machine.

description: An analogue of the theory of integral closure and reductions is developed for a more general class of closures, called Nakayama closures. It is shown that tight closure is a Nakayama closure by proving a ``Nakayama lemma for tight closure''. Then, after strengthening A. Vraciu's theory of $*$-independence and the special part of tight closure, it is shown that all minimal $*$-reductions of an ideal in an analytically irreducible excellent local ring of positive characteristic have the same minimal number of generators. This number is called the $*$-spread of the ideal, by analogy with the notion of analytic spread.
