description: Inspired by the magnificent features of two-dimensional (2D) materials which aroused much of the interest in recent materials science research, we study PT-symmetric 2D Weyl semimetal (WSM) to reveal the broadband and wide-angle invisible configurations in a PT-symmetric optical slab system. Desired unidirectional reflectionlessness and invisibility phenomena is obtained by the optimal control of system parameters. We unravel the mystery of broadband and wide-angle invisibility in regular slab materials with finite refractive indices by means of the plenary expressions. We show that materials whose refractive indices relatively small (usually around $η=1$) give rise to quite a lot broadband and wide-angle (almost all incidence angles) invisible configurations. This is not observed with any 2D material other than 2D WSMs. Our findings suggest a concrete expedience to experimental realizations in this direction.

description: We report high spectral resolution Australia Telescope Compact Array HI 21 cm observations resulting in the detection of the warm neutral medium (WNM) of the Galaxy in absorption against two extragalactic radio sources, PKS 1814-637 and PKS 0407-658. The two lines of sight were selected on the basis of the simplicity of their absorption profiles and the strength of the background sources; the high velocity resolution of the spectra then enabled us to estimate the kinetic temperatures of the absorbing gas by fitting multiple Gaussians to the absorption profiles. Four separate WNM components were detected toward the two sources, with peak optical depths $τ_{max} = (1.0 \pm 0.08) \times 10^{-2}$, $(1.4 \pm 0.2) \times 10^{-3}$, $(2.2 \pm 0.5) \times 10^{-3}$ and $(3.4 \pm 0.5) \times 10^{-3}$ and kinetic temperatures $T_{k} = 3127 \pm 300$ K, $3694 \pm 1595$ K, $3500 \pm 1354$ K and $2165 \pm 608$ K respectively. All four components were thus found to have temperatures in the thermally unstable range $500 < T_{k} < 5000$ K; this suggests that thermal equilibrium has not been reached throughout the WNM.

description: A problemática das políticas de salvaguarda do património e da constituição de uma memória digital são, desde há muito, preocupação da área das bibliotecas e dos arquivos em geral, dado que estes organismos constituem casos complexos, devido não só à sua dimensão, mas sobretudo à sua natureza, uma vez que contêm acervos múltiplos, correspondentes a lógicas e modelos institucionais multisseculares. Contando com o contributo de vários especialistas nacionais e internacionais, são abordadas questões relativas à salvaguarda e valorização do património arquivístico à guarda das instituições, quer em suporte tradicional quer em suporte digital, e é discutida a necessidade de dotar os organismos públicos e privados dos meios técnicos e humanos para o seu tratamento e disponibilização, com o necessário recurso às tecnologias adequadas. Sendo os fundos arquivísticos as primeiras fontes da nossa memória individual e colectiva, têm particular e reconhecido relevo para o conhecimento e a investigação científica, hoje também já noutras actividades como a gestão e a administração, com particular ênfase na “gestão documental” e no apoio aos processos de decisão, permitindo obter níveis de eficácia e eficiência fundamentais para o desenvolvimento e o bem-estar na sociedade actual. Com a temática do presente número dos Cadernos BAD, a Associação Portuguesa de Bibliotecários Arquivistas e Documentalistas, pretendeu lançar as bases de discussão e reflexão sobre o enquadramento conceptual e a implementação das POLÍTICAS DE SALVAGUARDA DO PATRIMÓNIO E MEMÓRIA DIGITAL, que assumem extrema importância na actual sociedade da informação e do conhecimento. A edição do n.° 2 de 2005 dos Cadernos BAD sofreu considerável atraso que se deve a condicionalismos vários, decorrentes de imprevistos ao longo de todo o processo. Aos nossos associados e leitores, apresentamos as nossas desculpas pelo atraso na edição mas estamos certos que o resultado final justificou a espera.

description: We construct explicitly a (12g-12)-dimensional space P of unconstrained and independent initial data for 't Hooft's polygon model of (2+1) gravity for vacuum spacetimes with compact genus-g spacelike slices, for any g >= 2. Our method relies on interpreting the boost parameters of the gluing data between flat Minkowskian patches as the lengths of certain geodesic curves of an associated smooth Riemann surface of the same genus. The appearance of an initial big-bang or a final big-crunch singularity (but never both) is verified for all configurations. Points in P correspond to spacetimes which admit a one-polygon tessellation, and we conjecture that P is already the complete physical phase space of the polygon model. Our results open the way for numerical investigations of pure (2+1) gravity.

A lower bound for the Wehrl entropy of quantum spin with sharp high-spin asymptotics

description: A lower bound for the Wehrl entropy of a single quantum spin is derived. The high-spin asymptotics of this bound coincides with Lieb's conjecture up to, but not including, terms of first and higher order in the inverse spin quantum number. The result presented here may be seen as complementary to the verification of the conjecture in cases of lowest spin by Schupp [Commun. Math. Phys. 207 (1999), 481]. The present result for the Wehrl-entropy is obtained from interpolating a sharp norm bound that also implies a sharp lower bound for the so-called Rényi-Wehrl entropy with certain indices that are evenly spaced by half of the inverse spin quantum number.

description: We introduce Grinch, a new algorithm for large-scale, non-greedy hierarchical clustering with general linkage functions that compute arbitrary similarity between two point sets. The key components of Grinch are its rotate and graft subroutines that efficiently reconfigure the hierarchy as new points arrive, supporting discovery of clusters with complex structure. Grinch is motivated by a new notion of separability for clustering with linkage functions: we prove that when the model is consistent with a ground-truth clustering, Grinch is guaranteed to produce a cluster tree containing the ground-truth, independent of data arrival order. Our empirical results on benchmark and author coreference datasets (with standard and learned linkage functions) show that Grinch is more accurate than other scalable methods, and orders of magnitude faster than hierarchical agglomerative clustering.

description: Desenvolver e executar uma estratégia nacional da informação foi um interesse chave quer para a Escócia quer para a área das ciências da informação (LIS). O presente artigo descreve os elementos necessários que permitem tornar uma estratégia nacional de informação uma realidade e o papel que os repositórios institucionais devem desempenhar em tal estratégia. O uso de repositórios institucionais – como meios de permitir o acesso à produção científica produzida na Escócia – sustenta um número dos factores chave ao nível político, social e económico intrínsecos à própria realidade escocesa. Os repositórios institucionais podem justificar o trabalho das instituições de ensino superior (HE) fornecendo meios de gestão de dados e promovendo soluções de pesquisa. No entanto, só se poderão colher os frutos destes benefícios, se os bibliotecários forem colocados no epicentro desta visão estratégica; as suas competências e conhecimentos informam a execução e a gestão correcta de repositórios que deverão ser globais e interoperativos. A emergência de um repositório baseado numa infra-estrutura nacional distribuída na Escócia é, também, explorada, assim como o abrangente papel pretendido para o novo projecto denominado IRIScotland.

description: The implementation of various methods for the determination of gamma through direct CP violation arising in the interference of b->c and b->u processes in charged as well as neutral B meson decays are considered. We show that the inclusion of D0 resulting from D*0-->D0+pi0(gamma) say via B-->KD*0 makes a significant difference in the attainable accuracy for gamma. Both exclusive and inclusive decays of the B+- and B0 to states containing D0/D0-bar followed by both inclusive and exclusive decays of the D0 are discussed. It is shown that with statistics which might be obtained at B factories (5-10 X 10^8 B-pairs) a 1-sigma determination of gamma to about +-5 degrees may be possible depending on the efficiency of reconstruction, backgrounds and the details of the decay amplitudes involved. The role of data from a charm factory as well as effects of D0 mixing are discussed. Extraction of gamma with accuracy that is roughly commensurate with the intrinsic theory error of these methods (i.e. around 0.1%), which is an important goal, will require >10^{10} B-pairs, namely a Super-B Factory.

A theoretical investigation using the normality assumption demonstrates the potential severity of these problems and empirical results from farm-level data lend further support.

description: We study the entanglement properties in non-equilibrium quantum systems with the SU(1, 1) structure. Through Möbius transformation, we map the dynamics of these systems following a sudden quench or a periodic drive onto three distinct trajectories on the Poincaré disc, corresponding the heating, non-heating, and a phase boundary describing these non-equilibrium quantum states. We consider two experimentally feasible systems where their quantum dynamics exhibit the SU(1, 1) structure: the quench dynamics of the Bose-Einstein condensates and the periodically driven coupled oscillators. In both cases, the heating, non-heating phases, and their boundary manifest through distinct signatures in the phonon population where exponential, oscillatory, and linear growths classify these phases. Similarly, the entanglement entropy and negativity also exhibit distinct behaviors (linearly, oscillatory, and logarithmic growths) characterizing these phases, respectively. Notibly, for the periodically driven coupled oscillators, the non-equilibrium properties are characterized by two sets of SU(1, 1) generators. The corresponding two sets of the trajectories on two Poincaré discs lead to a more complex phase diagram. We identify two distinct phases within the heating region discernible solely by the growth rate of the entanglement entropy, where a discontinuity is observed when varying the parameters across the phase boundary within in heating region. This discontinuity is not observed in the phonon population.

description: We construct a stable homotopy refinement of quantum annular homology, a link homology theory introduced by Beliakova, Putyra and Wehrli. For each $r\geq 2$ we associate to an annular link $L$ a naive $\mathbb{Z}/r\mathbb{Z}$-equivariant spectrum whose cohomology is isomorphic to the quantum annular homology of $L$ as modules over $\mathbb{Z}[\mathbb{Z}/r\mathbb{Z}]$. The construction relies on an equivariant version of the Burnside category approach of Lawson, Lipshitz and Sarkar. The quotient under the cyclic group action is shown to recover the stable homotopy refinement of annular Khovanov homology. We study spectrum level lifts of structural properties of quantum annular homology.

description: A evolução do conhecimento assenta numa eficaz comunicação dos resultados da investigação. As descobertas necessitam ser largamente disseminadas para que outros investigadores possam construir a partir delas o seu próprio saber, contribuindo, assim, para dar corpo e expandir o conhecimento. A Internet dá-nos oportunidades nunca antes sonhadas para nos assegurarmos de que todos aqueles que podem beneficiar do acesso à investigação tenham efectivo acesso a ela. Infelizmente, o actual modelo económico (subscrições, “grandes negócios”, etc.) restringe o acesso àqueles que podem proceder ao pagamento. Este facto retarda todo o processo de pesquisa e conduz às ineficiências da comunicação do conhecimento. O Open Access dá-nos um modelo em que o acesso é alargado a toda a comunidade académica, em todo o mundo. Este artigo descreve duas modalidades complementares do acesso livre (repositórios e artigos de publicações periódicas em acesso livre) e dá exemplos dos passos que estão a ser dados no sentido de implementar o acesso livre para benefício dos autores, dos leitores e da sociedade em geral.

description: Producers confronted with pest management problems must continually update information on the state of the crop, the level of pest infestation, and other factors to modify their conception of the evolving state. Determination of economic thresholds have at most been based on informational feedback systems that do not take into account possibilities for revision based on •the expected states of the crop system in future periods. This paper develops a framework for applying an adaptive control methodology to pest management decisions to fully consider both present and expected future information states. By incorporating anticipated revision of producers' decisions in an adaptive control scheme, it is expected that better production system performance can be realized.

description: Two emerging areas of research, attosecond and nanoscale physics, have recently started to merge. Attosecond physics deals with phenomena occurring when ultrashort laser pulses, with duration on the femto- and sub-femtosecond time scales, interact with atoms, molecules or solids. The laser-induced electron dynamics occurs natively on a timescale down to a few hundred or even tens of attoseconds (1 attosecond=1 as=10$^{-18}$ s), which is of the order of the optical field cycle. For comparison, the revolution of an electron on a $1s$ orbital of a hydrogen atom is $\sim152$ as. On the other hand, the second topic involves the manipulation and engineering of mesoscopic systems, such as solids, metals, and dielectrics, with nanometric precision. Although nano-engineering is a vast and well-established research field on its own, the combination with intense laser physics is relatively recent. We present a comprehensive theoretical overview of the tools to tackle and understand the physics that takes place when short and intense laser pulses interact with nanosystems, such as metallic and dielectric nanostructures. In particular, we elucidate how the spatially inhomogeneous laser-induced fields at a nanometer scale modify the laser-driven electron dynamics. Consequently, this has an important impact on pivotal processes such as above-threshold ionization and high-order harmonic generation. The deep understanding of the coupled dynamics between these spatially inhomogeneous fields and matter configures a promising way to new avenues of research and applications. Thanks to the maturity that attosecond physics has reached, together with the tremendous advance in material engineering and manipulation techniques, the age of atto-nano physics has begun, but it is still in an incipient stage.

description: We present deep Halpha spectroscopy towards several high-velocity clouds (HVCs) which vary in structure from compact (CHVCs) to the Magellanic Stream. The clouds range from being bright (~640 mR) to having upper limits on the order of 30 to 70 mR. The Halpha measurements are discussed in relation to their HI properties and distance constraints are given to each of the complexes based on f_esc = 6% of the ionizing photons escaping normal to the Galactic disk (f_escs = 1 - 2% when averaged over solid angle). The results suggest that many HVCs and CHVCs are within a ~40 kpc radius from the Galaxy and are not members of the Local Group at megaparsec distances. However, the Magellanic Stream is inconsistent with this model and needs to be explained. It has bright Halpha emission and little [NII] emission and appears to fall into a different category than the currently detected HVCs. This may reflect the lower metallicities of the Magellanic Clouds compared to the Galaxy, but the strength of the Halpha emission cannot be explained solely by photoionization from the Galaxy. The interaction of the Stream with halo gas or the presence of yet unassociated young stars may assist in ionizing the Stream.

description: The ISO 26262 is currently the dominant standard for assuring functional safety of electrical and electronic systems in the automotive industry. The Functional Safety Concept (FSC) subphase in the standard requires the Preliminary Architectural Assumptions (PAA) for allocation of functional safety requirements (FSRs). This paper justifies the need for, and defines a process ATRIUM, for consistent design of the PAA. ATRIUM is subsequently applied in an industrial case study for a function enabling highly automated driving at one of the largest heavy vehicle manufacturers in Europe, Scania CV AB. The findings from this study, which contributed to ATRIUM's institutionalization at Scania, are presented. The benefits of the proposed process include (i) a fast and flexible way to refine the PAA, and a framework to (ii) incorporate information from legacy systems into safety design and (iii) rigorously track and document the assumptions and rationale behind architectural decisions under uncertain information. The contributions of this paper are the (i) analysis of the problem (ii) the process ATRIUM and (iii) findings and the discussion from the case study at Scania.

description: Foi com o objectivo de dar conta da discussão internacional sobre o tema do livre acesso ao conhecimento científico que este número dos Cadernos BAD foi pensado, procurando ser mais um contributo para o estudo daquela problemática. O importante desafio que a investigação representa, tanto em matéria de conhecimento como de desenvolvimento, salienta-se num dos artigos, obriga a que se comecem a utilizar, de forma sistemática, canais optimizados de livre comunicação entre a comunidade académica e, por isso, a acção concertada entre instituições e indivíduos se revela tão importante na implementação das políticas de livre acesso. A impossibilidade de encarar o futuro da comunicação académica sem ter em linha de conta o livre acesso é abordada mais adiante, apontando-se para a importância da política de auto-arquivo, de acordo com os princípios do paradigma de acesso livre, e para o papel que os repositórios institucionais desempenham nas universidades em Portugal, na Europa e no mundo. A forma como estes novos modelos se tornam essenciais em áreas onde os princípios de livre acesso à informação e ao conhecimento se prendem aos do direito a esse acesso, como é o caso das ciências da saúde, é aqui assinalada sendo apontados exemplos em que as duas vias alternativas e complementares do livre acesso têm coexistido pacificamente: a publicação de trabalhos científicos em revistas editadas em open access e a de artigos publicados em revistas científicas tradicionais disponíveis em open archives. O potencial desta nova forma de acesso à literatura científica não nos pode deixar indiferentes. Todos os intervenientes no processo sabem ser irreversível o caminho já percorrido por este movimento, apenas subordinado, em última análise, às preocupações de estímulo à criatividade e à inovação. Os profissionais de informação portugueses, reunidos no 8.º Congresso Nacional de Bibliotecários, Arquivistas e Documentalistas, em Maio de 2004, no Estoril, já reconheceram e apoiaram as definições, objectivos e princípios do acesso livre tal como definidos na Declaração da Budapest Open Access Initiative e na Declaração de Berlim sobre o Acesso ao Conhecimento nas Ciências e Humanidades. Que este número dos Cadernos BAD cumpra o seu objectivo ao reintroduzir a reflexão directa e indirecta em questões sobre as quais nunca está tudo dito… Porque suscitam a vontade de repensar. Para aprender. Para agir.

Vortices in Spatially Inhomogeneous Superfluids

description: We study vortices in a radially inhomogeneous superfluid, as realized by a trapped degenerate Bose gas in a uniaxially symmetric potential. We show that, in contrast to a homogeneous superfluid, an off-axis vortex corresponds to an anisotropic superflow whose profile strongly depends on the distance to the trap axis. One consequence of this superflow anisotropy is vortex precession about the trap axis in the absence of an imposed rotation. In the complementary regime of a finite prescribed rotation, we compute the minimum-energy vortex density, showing that in the rapid-rotation limit it is extremely uniform, despite a strongly inhomogeneous (nearly) Thomas-Fermi condensate density $ρ_s(r)$. The weak radially-dependent contribution ($\propto \nabla^2\lnρ_s(r)$) to the vortex distribution, that vanishes with the number of vortices $N_v$ as $\frac{1}{N_v}$, arises from the interplay between vortex quantum discretness (namely their inability to faithfully support the imposed rigid-body rotation) and the inhomogeneous superfluid density. This leads to an enhancement of the vortex density at the center of a typical concave trap, a prediction that is in quantitative agreement with recent experiments (cond-mat/0405240). One striking consequence of the inhomogeneous vortex distribution is an azimuthally-directed, radially-shearing superflow.

The generalized Fuglede's conjecture holds for a class of Cantor-Moran measures

description: Suppose ${\bf b}=\{b_n\}_{n=1}^{\infty}$ is a sequence of integers bigger than 1 and ${\bf D}=\{{\mathcal D}_{n}\}_{n=1}^{\infty}$ is a sequence of consecutive digit sets. Let $μ_{{\bf b},{\bf D}}$ be the Cantor-Moran measure defined by \begin{eqnarray*}
 μ_{{\bf b},{\bf D}}&=& δ_{\frac{1}{b_1}{\mathcal D}_{1}}\astδ_{\frac{1}{b_1b_2}{\mathcal D}_{2}}\ast δ_{\frac{1}{b_1b_2b_3}{\mathcal D}_{3}}\ast\cdots.
 \end{eqnarray*}
 We prove that $L^2(μ_{{\bf b},{\bf D}})$ possesses an exponential orthonormal basis if and only if $μ_{{\bf b},{\bf D}}\astν={\mathcal L}_{[0,N_1/b_1]}$ for some Borel probability measure $ν$.
 This theorem shows that the generalized Fuglede's conjecture is true for such Cantor-Moran measure. An immediate consequence of this result is the equivalence between the existence of an exponential orthonormal basis and the integral tiling of ${\bf D}_n={\mathcal D}_{n}+b_n{\mathcal D}_{n-1}+b_2\cdots b_n{\mathcal D}_{1}$ for $n\geq1$.

Hybrid PDE-ODE Models for Efficient Simulation of Infection Spread in Epidemiology

description: This paper introduces a novel hybrid model combining Partial Differential Equations (PDEs) and Ordinary Differential Equations (ODEs) to simulate infectious disease dynamics across geographic regions. By leveraging the spatial detail of PDEs and the computational efficiency of ODEs, the model enables rapid evaluation of public health interventions. Applied to synthetic environments and real-world scenarios in Lombardy, Italy, and Berlin, Germany, the model highlights how interactions between PDE and ODE regions affect infection dynamics, especially in high-density areas. Key findings reveal that the placement of model boundaries in densely populated regions can lead to inaccuracies in infection spread, suggesting that boundaries should be positioned in areas of lower population density to better reflect transmission dynamics. Additionally, regions with low population density hinder infection flow, indicating a need for incorporating, e.g., jumps in the model to enhance its predictive capabilities. Results indicate that the hybrid model achieves a balance between computational speed and accuracy, making it a valuable tool for policymakers in real-time decision-making and scenario analysis in epidemiology and potentially in other fields requiring similar modeling approaches.

 Syntypes. Two specimens, MNHN 1883.580 and MNHN 1895.255 collected by Humblot and Grandidier, from ‘ Madagascar... côte Est’.
 Referred material. For field numbers of additional specimens referred to M. grandidieri genetically, see Figure 1. For morphological measurements of types and additional six specimens in the ZSM collection, see Table 1.
 Remarks. Mantidactylus (M.) grandidieri is a large nocturnal stream-dwelling frog, distributed at elevations from near sea level (Nosy Mangabe) to ca. 1500 m a.s.l. (Ambohitantely), but appears to be more common at low elevations <900 m a.s.l. It is found in slow-moving parts of streams in rainforest, often among rocks and boulders, and almost nothing is known about its natural history. Based on genetic data herein, confirmed localities are (from north to south) Marojejy, Sambava, Besariaka, Tsararano, Antalaha, Masoala, Ilampy, Ambodivoangy, Andranofotsy, Nosy Mangabe, Angozongahy (west slope of Makira Reserve), Antsahataloka, Ambatoroma, Ambohitantely, Ambatodisakoana, Fierenana, Vohidrazana, Moramanga and the Mangabe region.
 As with M. guttulatus, the definition of this species has changed multiple times in the past. A complete revision of all these uses in the literature is beyond the scope of this paper. Glaw and Vences (2007) partially following Blommers-Schlösser and Blanc (1991) used the name M. grandidieri primarily to refer to highland populations in the Northern Central East and Southern Central East, which, according to the present revision, are to be referred to as M. guttulatus. Instead, populations of M. grandidieri were named Mantidactylus sp. aff. grandidieri ‘North’ by Glaw and Vences (2007), Mantidactylus sp. 57 by Vieites et al. (2009) and Mantidactylus sp. Ca57 by Perl et al. (2014).

description: We examine the manifestation of transient effects in fission by analysing experimental data where fission is induced by peripheral heavy-ion collisions at relativistic energies. Available total nuclear fission cross sections of 238U at 1 A GeV on gold and uranium targets are compared with a nuclear-reaction code, where transient effects in fission are modelled using different approximations to the numerical time-dependent fission-decay width: a new analytical description based on the solution of the Fokker-Planck equation and two widely used but less realistic descriptions, a step function and an exponential-like function. The experimental data are only reproduced when transient effects are considered. The deduced value of the dissipation strength depends strongly on the approximation applied for the time-dependent fission-decay width and is estimated to be of the order of 2x10**21 s**(-1). A careful analysis sheds severe doubts on the use of the exponential-like in-growth function largely used in the past. Finally, we discuss which should be the characteristics of experimental observables to be most sensitive to transient effects in fission

description: Здійснено системний аналіз сталого розвитку еколого-економічних систем. Визначено загальносистемні принципи і закономірності функціонування складних систем, на основі яких повинна бути сформована загальна теорія сталого розвитку. Розглянуто сучасну практику містобудівних інновацій, що заснована на принципах біосферної сумісності. Істотну роль у цьому відіграє узгоджене застосування техніко-технологічних та організаційно-економічних інновацій у ресурсно-екологічній сфері. Набули подальшого розвитку методологічні підходи до формування механізмів управління сталим розвитком еколого-економічних систем на основі побудови партиципаторної моделі розвитку інвестиційної інфраструктури регіону (на прикладі конкурентоспроможності регіональних ринків житла).
