description: El deber de información tiene origen en la buena fe, y consiste en cooperar y hacer saber a la contraparte todas aquellas circunstancias y situaciones relevantes para la relación negocial tanto en su etapa precontractual como contractual. Sin embargo, este deber no es absoluto y tiene límites establecidos por la misma buena fe, permitiendo, por una parte, que quien ha invertido en la generación y desarrollo de conocimiento pueda sacar rendimientos de esa inversión, y por otra parte, que no haya un estímulo o subsidio a la negligencia de quien no se procura la información que necesita. Igual sucede en la contratación internacional, escenario en el que confluyen diversos intereses, algunos de los cuales justifican la reserva de información y otros promueven su revelación. Este trabajo analiza esos escenarios y presenta una aproximación a la concreción del deber de información en la contratación internacional a través fuentes endógenas y exógenas al contrato, donde los presupuestos de la buena fe se complementan con criterios propios de la contratación contemporánea, buscando así un mercado con actores comprometidos con la satisfacción de sus grupos de interés, cimentando relaciones cooperativas, transparentes y constructivas.
description: The duty of disclosure of information is derived from good faith and involves cooperation and informing de counterparty of all relevant circumstances and situations for the business relationship, both in pre-contractual and contractual stages. However, the duty of disclosure is not absolute and is limited by good faith itself, allowing, on one hand, those who have invested in generating and developing knowledge to profit from it, and on the other hand, preventing the negligence of those who do not procure the necessary information they need. This also occurs in international contracting, a scenario where various interests converge, some of which promote the reservation of information and others its disclosure. This paper analyzes those scenarios and presents an approach to the concretization of the duty of disclosure in international contracting through sources that are both endogenous and exogenous to the contract, where the principle of good faith is complemented by criteria of contemporary contracting, seeking a market with actors committed to satisfying their stakeholders, solidifying cooperative, transparent, and constructive relationships.

description: The calculation of realistic N-body wave functions for identical fermions is still an open problem in physics, chemistry, and materials science, even for N as small as two. A recently discovered fundamental algebraic structure of many-body Hilbert space allows an arbitrary many-fermion wave function to be written in terms of a finite number of antisymmetric functions called shapes. Shapes naturally generalize the single-Slater-determinant form for the ground state to more than one dimension. Their number is exactly $N!^{d-1}$ in $d$ dimensions. An efficient algorithm is described to generate all fermion shapes in spaces of odd dimension, which improves on a recently published general algorithm. The results are placed in the context of contemporary investigations of strongly correlated electrons.

description: El Gas Natural Licuado (GNL) se ha posicionado en el mundo como una de las fuentes de combustibles más limpias y eficientes. En los últimos años ha venido emergiendo como un actor crucial en la matriz energética global, desempeñando un papel fundamental en la transición hacia un futuro más sostenible; su versatilidad facilita no solo su almacenamiento sino también su transporte a largas distancias, ampliando a su vez, su acceso a regiones geográficas que anteriormente han enfrentado limitaciones logísticas para el suministro de este combustible. La incorporación del GNL en la matriz energética, fortalece la seguridad en el sector de gas combustible, al permitir avanzar hacia la diversificación de fuentes de suministro, reduciendo así la vulnerabilidad ante posibles escenarios de desabastecimiento y disminuyendo la dependencia de una sola fuente de suministro.
description: Liquefied Natural Gas (LNG) has positioned itself globally as one of the cleanest and most efficient fuel sources. In recent years, it has emerged as a crucial player in the global energy matrix, playing a fundamental role in the transition towards a more sustainable future. Its versatility not only facilitates storage but also long-distance transportation, thereby expanding its access to geographical regions that previously faced logistical limitations in the supply of this fuel. The integration of LNG into the energy matrix strengthens security in the fuel gas sector by allowing progress towards the diversification of supply sources, thereby reducing vulnerability to potential supply disruptions, and decreasing dependence on a single supply source.

description: Spatial coexistence of coherent and incoherent dynamics in network of coupled oscillators is called a chimera state. We study such chimera states in a network of neurons without any direct interactions but connected through another medium of neurons, forming a multilayer structure. The upper layer is thus made up of uncoupled neurons and the lower layer plays the role of a medium through which the neurons in the upper layer share information among each other. Hindmarsh-Rose neurons with square wave bursting dynamics are considered as nodes in both layers. In addition, we also discuss the existence of chimera states in presence of inter layer heterogeneity. The neurons in the bottom layer are globally connected through electrical synapses, while across the two layers chemical synapses are formed. According to our research, the competing effects of these two types of synapses can lead to chimera states in the upper layer of uncoupled neurons. Remarkably, we find a density-dependent threshold for the emergence of chimera states in uncoupled neurons, similar to the quorum sensing transition to a synchronized state. Finally, we examine the impact of both homogeneous and heterogeneous inter-layer information transmission delays on the observed chimera states over a wide parameter space.

description: Cells of the immune system are confronted with opposing pro- and anti-inflammatory signals. Dendritic cells (DC) integrate these cues to make informed decisions whether to initiate an immune response. Confronted with exogenous microbial stimuli, DC endogenously produce both anti- (IL-10) and pro-inflammatory (TNF$α$) cues whose joint integration controls the cell's final decision. We combine experimental measurements with theoretical modeling to quantitatively describe the integration mode of these opposing signals. We propose a two step integration model that modulates the effect of the two types of signals: an initial bottleneck integrates both signals (IL-10 and TNF$α$), the output of which is later modulated by the anti-inflammatory signal. We show that the anti-inflammatory IL-10 signaling is long ranged, as opposed to the short-ranged pro-inflammatory TNF$α$ signaling. The model suggests that the population averaging and modulation of the pro-inflammatory response by the anti-inflammatory signal is a safety guard against excessive immune responses.

description: We present observations of three active sites of star formation in the Taurus Molecular Cloud complex taken at 323 and 608 MHz (90 and 50 cm, respectively) with the Giant Metrewave Radio Telescope (GMRT). Three pointings were observed as part of a pathfinder project, targeted at the young stellar objects (YSOs) L1551 IRS 5, T Tau and DG Tau (the results for these target sources were presented in a previous paper). In this paper, we search for other YSOs and present a survey comprising of all three fields; a by-product of the large instantaneous field of view of the GMRT. The resolution of the survey is of order 10 arcsec and the best rms noise at the centre of each pointing is of order $100\,μ$Jy beam$^{-1}$ at 323 MHz and $50\,μ$Jy beam$^{-1}$ at 608 MHz. We present a catalogue of 1815 and 687 field sources detected above $5\,σ_{\rm rms}$ at 323 and 608 MHz, respectively. A total of 440 sources were detected at both frequencies, corresponding to a total unique source count of 2062 sources. We compare the results with previous surveys and showcase a sample of extended extragalactic objects. Although no further YSOs were detected in addition to the target YSOs based on our source finding criteria, these data can be useful for targeted manual searches, studies of radio galaxies or to assist in the calibration of future observations with the Low Frequency Array (LOFAR) towards these regions.

description: We present a new YAuSi Liquid Metal Alloy Ion Source (LMAIS), generating focused ion beams of yttrium ions, and its prospective applications for nanofabrication, sample preparation, lithographic and implantation processes. Working parameters of the AuSiY LMAIS are similar to other gold-silicon based LMAIS. We found anomalously high emission current of triple charged Yttrium ions. Influence of Yttrium implantation on optical qualities of the implanted ion-ensembles is shown in luminescence of co-implanted Erbium ions.

description: Location-based social media make it possible to understand social and geographic aspects of human activities. However, previous studies have mostly examined these two aspects separately without looking at how they are linked. The study aims to connect two aspects by investigating whether there is any correlation between social connections and users' check-in locations from a socio-geographic perspective. We constructed three types of networks: a people-people network, a location-location network, and a city-city network from former location-based social media Brightkite and Gowalla in the U.S., based on users' check-in locations and their friendships. We adopted some complexity science methods such as power-law detection and head/tail breaks classification method for analysis and visualization. Head/tail breaks recursively partitions data into a few large things in the head and many small things in the tail. By analyzing check-in locations, we found that users' check-in patterns are heterogeneous at both the individual and collective levels. We also discovered that users' first or most frequent chec-in locations can be the representatives of users' spatial information. The constructed networks based on these locations are very heterogeneous, as indicated by the high ht-index. Most importantly, the node degree of the networks correlates highly with the population at locations (mostly with R-square being 0.7) or cities (above 0.9). This correlation indicates that the geographic distributions of the social media users relate highly to their online social connections.

description: Non-Abelian gauge fields are versatile tools for synthesizing topological phenomena but have so far been mostly studied in Hermitian systems, where gauge flux has to be defined from a closed loop in order for gauge fields, whether Abelian or non-Abelian, to become physically meaningful. We show that this condition can be relaxed in non-Hermitian systems by proposing and studying a generalized Hatano--Nelson model with imbalanced non-Abelian hopping. Despite lacking gauge flux in one dimension, non-Abelian gauge fields create rich non-Hermitian topological consequences. Under only nearest-neighbor coupling, non-Abelian gauge fields enable Hopf-link bulk braiding topology, whose phase transition accompanies the emergence of exceptional points (EPs). At both ends of an open chain, non-Abelian gauge fields lead to the simultaneous presence of non-Hermitian skin modes, whose population can be effectively tuned. Asymptotic analysis shows that this tuning mechanism stems from the interplay between the Abelian Hatano--Nelson coupling and effective high-order hopping, which becomes substantial near the EP phase transition condition. The predicted non-Hermitian phenomena, enabled by non-Abelian gauge fields, could be realized in synthetic dimensional optical platforms such as time-multiplexed photonic mesh lattices and driven ring resonators.

description: Saturn's quasi-periodic planet-encircling storms are the largest convecting outbursts in the Solar System. The last eruption was in 1990. A new eruption started in December 2010 and presented the first-ever opportunity to observe such episodic storms from a spacecraft in orbit around Saturn. Here, we analyze images acquired with the Cassini Imaging Science Subsystem (ISS), which captured the storm's birth, evolution and demise. In studying the end of the convective activity, we also analyze the Saturn Electrostatic Discharge (SED) signals detected by the Radio and Plasma Wave Science (RPWS) instrument. [...]

description: The continuous software engineering paradigm is gaining popularity in modern development practices, where the interleaving of design and runtime activities is induced by the continuous evolution of software systems. In this context, performance assessment is not easy, but recent studies have shown that architectural models evolving with the software can support this goal. In this paper, we present a mapping study aimed at classifying existing scientific contributions that deal with the architectural support for performance-targeted continuous software engineering. We have applied the systematic mapping methodology to an initial set of 215 potentially relevant papers and selected 66 primary studies that we have analyzed to characterize and classify the current state of research. This classification helps to focus on the main aspects that are being considered in this domain and, mostly, on the emerging findings and implications for future research

description: The microwave radio dynamic spectra of the Crab pulsar interpulse contain fine structures represented via narrowband quasiharmonic stripes. The pattern significantly constrains any potential emission mechanism. Similar to the zebra patterns observed, for example, in type IV solar radio bursts or decameter and kilometer Jupiter radio emission, the double plasma resonance (DPR) effect of the cyclotron maser instability may allow for interpretion of observations of pulsar radio zebras. We present electromagnetic relativistic particle-in-cell (PIC) simulations of the electron-positron cyclotron maser for cyclotron frequency smaller than the plasma frequency. In four distinct simulation cycles, we focused on the effects of varying the plasma parameters on the instability growth rate and saturation energy. The physical parameters were the ratio between the plasma and cyclotron frequency, the density ratio of the "hot" loss-cone to the "cold" background plasma, the loss-cone characteristic velocity, and comparison with electron-proton plasma. In contrast to the results obtained from electron-proton plasma simulations, we find that the pulsar electron-positron maser instability does not generate distinguishable X and Z modes. On the contrary, a singular electromagnetic XZ mode was generated in all studied configurations close to or above the plasma frequency. For low density ratios, the highest peak of the XZ mode is at double the frequency of the highest peak of the Bernstein modes, indicating that the radio emission is produced by a coalescence of two Bernstein modes with the same frequency and opposite wave numbers. Our estimate of the radiative flux generated from the simulation is up to $\sim$30 mJy from an area of 100 km$^2$ for an observer at 1 kpc distance without the inclusion of relativistic beaming effects, which may account for multiple orders of magnitude.

description: Desde sus inicios, el principio de confianza legítima operó como garantía de la expectativa justificada del ciudadano en el mantenimiento de una situación jurídica creada o auspiciada por un acto administrativo, inclusive si éste nació con violación del principio de legalidad. Sin embargo, dado el papel que el Estado desempeña en otras esferas del poder, como, por ejemplo, el poder judicial, cabe preguntarse si el amparo de la confianza legítima juega en pro de los usuarios de la jurisdicción contencioso administrativa cuando se presenta cambio del precedente judicial con efectos retroactivos. Ahora, si la respuesta al anterior interrogante es afirmativa ¿constituye un fundamento válido de responsabilidad extracontractual del Estado juez la defraudación de la confianza legítima por cambio del precedente judicial del Consejo de Estado?
description: From its beginnings, the principle of legitimate expectations operated as a guarantee of the justified expectation of the citizen in the maintenance of a legal situation created or sponsored by an administrative act, even if it was born in violation of the principle of legality. However, given the role that the State plays in other spheres of power, such as, for example, the judiciary, it is worth asking whether the protection of legitimate expectations operates in favor of the users of the contentious-administrative jurisdiction when there is a change in the judicial precedent with retroactive effects. Now, if the answer to the above question is affirmative, does the violation of legitimate expectations due to a change in the judicial precedent of the Consejo de Estado constitute a valid basis for the extra-contractual liability of the judicial State?

description: For the past couple of decades, the Parkes radio telescope has been regularly observing the millisecond pulsars in 47 Tucanae (47 Tuc). This long-term timing program was designed to address a wide range of scientific issues related to these pulsars and the globular cluster where they are located. In this paper, the first of a series, we address one of these objectives: the characterization of four previously known binary pulsars for which no precise orbital parameters were known, namely 47 Tuc P, V, W and X (pulsars 47 Tuc R and Y are discussed elsewhere). We determined the previously unknown orbital parameters of 47 Tuc V and X and greatly improved those of 47 Tuc P and W. For pulsars W and X we obtained, for the first time, full coherent timing solutions across the whole data span, which allowed a much more detailed characterization of these systems. 47 Tuc W, a well-known tight eclipsing binary pulsar, exhibits a large orbital period variability, as expected for a system of its class. 47 Tuc X turns out to be in a wide, extremely circular, 10.9-day long binary orbit and its position is ~3.8 arcmin away from the cluster center, more than three times the distance of any other pulsar in 47 Tuc. These characteristics make 47 Tuc X a very different object with respect to the other pulsars of the cluster.

Liquid Water through Density-Functional Molecular Dynamics: Plane-Wave vs Atomic-Orbital Basis Sets

description: We determine and compare structural, dynamical, and electronic properties of liquid water at near ambient conditions through density-functional molecular dynamics simulations, when using either plane-wave or atomic-orbital basis sets. In both frameworks, the electronic structure and the atomic forces are self-consistently determined within the same theoretical scheme based on a nonlocal density functional accounting for van der Waals interactions. The overall properties of liquid water achieved within the two frameworks are in excellent agreement with each other. Thus, our study supports that implementations with plane-wave or atomic-orbital basis sets yield equivalent results and can be used indiscriminately in study of liquid water or aqueous solutions.

description: We analytically calculate the scaling exponents of a two-dimensional KPZ-like system: coherently moving incompressible polar active fluids. Using three different renormalization group approximation schemes, we obtain values for the ``roughness" exponent $χ$ and anisotropy exponent $ζ$ that are extremely near the known exact results. This implies our prediction for the previously completely unknown dynamic exponent $z$ is quantitatively accurate.

description: A beam optics scheme has been designed for the Future Circular Collider-e+e- (FCC-ee). The main characteristics of the design are: beam energy 45 to 175 GeV, 100 km circumference with two interaction points (IPs) per ring, horizontal crossing angle of 30 mrad at the IP and the crab-waist scheme [1] with local chromaticity correction. The crab-waist scheme is implemented within the local chromaticity correction system without additional sextupoles, by reducing the strength of one of the two sextupoles for vertical chromatic correction at each side of the IP. So-called "tapering" of the magnets is applied, which scales all fields of the magnets according to the local beam energy to compensate for the effect of synchrotron radiation (SR) loss along the ring. An asymmetric layout near the interaction region reduces the critical energy of SR photons on the incoming side of the IP to values below 100 keV, while matching the geometry to the beam line of the FCC proton collider (FCC-hh) [2] as closely as possible. Sufficient transverse/longitudinal dynamic aperture (DA) has been obtained, including major dynamical effects, to assure an adequate beam lifetime in the presence of beamstrahlung and top-up injection. In particular, a momentum acceptance larger than +/-2% has been obtained, which is better than the momentum acceptance of typical collider rings by about a factor of 2. The effects of the detector solenoids including their compensation elements are taken into account as well as synchrotron radiation in all magnets. The optics presented in this paper is a step toward a full conceptual design for the collider. A number of issues have been identified for further study.

description: High tunnels are a low-cost technology that can strengthen local and regional food systems by facilitating the production of high-quality fruits and vegetables during and beyond the frost-free growing season. The potential for high tunnels to improve crop quality and yield has been established with research trials, but there is a lack of research on the farm-level impacts of high tunnels, or comparisons between organic and conventional farming systems. This survey of high tunnel users in the U.S. Midwest state of Indiana finds that farmers have been successful with extending the growing season, as nearly half of the respondents are now harvesting in the cooler months and planting earlier in the spring. Farmers also reported significant increases in the productivity and quality of their crops year-round, and improvement in their farm’s economic stability. Farm-level impacts were similar for farmers using organic and conventional farming practices, although farmers using organic practices were more likely to increase their off-season production than their conventional counterparts. Overall, high tunnels hold potential as a tool for increasing the availability of fresh vegetables and fruits for local food systems, thus increasing the viability of Midwest farms.
Nearly Critical Superfluids in Keldysh-Schwinger Formalism

description: We examine the effective theory of critical dynamics near superfluid phase transitions in the framework of the Keldysh-Schwinger formalism. We focus on the sector capturing the dynamics of the complex order parameter and the conserved current corresponding to the broken global symmetry. After constructing the theory up to quadratic order in the $a$-fields, we compare the resulting stochastic system with Model F as well as with holography. We highlight the role of a time independent gauge symmetry of the effective theory also known as ``chemical shift". Finally, we consider the limiting behaviour at energies much lower than the gap of the amplitude mode by integrating out the high energy degrees of freedom to reproduce the effective theory of superfluids.

Dominating sets and ego-centered decompositions in social networks

description: Our aim here is to address the problem of decomposing a whole network into a minimal number of ego-centered subnetworks. For this purpose, the network egos are picked out as the members of a minimum dominating set of the network. However, to find such an efficient dominating ego-centered construction, we need to be able to detect all the minimum dominating sets and to compare all the corresponding dominating ego-centered decompositions of the network. To find all the minimum dominating sets of the network, we are developing a computational heuristic, which is based on the partition of the set of nodes of a graph into three subsets, the always dominant vertices, the possible dominant vertices and the never dominant vertices, when the domination number of the network is known. To compare the ensuing dominating ego-centered decompositions of the network, we are introducing a number of structural measures that count the number of nodes and links inside and across the ego-centered subnetworks. Furthermore, we are applying the techniques of graph domination and ego=centered decomposition for six empirical social networks.
