Coarse-to-fine localization of underwater acoustic communication receivers
Authors: He Pan , Shen Lu , Henson Benjamin , Zakharov Yuriy 
Published: July 2022

<p> Underwater acoustic (UWA) communication is an essential part of many civilian and military applications. For UWA sensor networks, the sensing information can only be interpreted meaningfully when the location of the sensor node is known. However, node localization is a challenging problem. Global Navigation Satellite Systems (GNSS), which are often used in terrestrial applications, do not work underwater. In this paper, we propose and investigate techniques for localization of a single-antenna UWA communication receiver with respect to one or more transmit antennas. These techniques are based on the matched field processing. Firstly, we demonstrate that a non-coherent ambiguity function (AF) allows significant improvement in the localization performance compared to the coherent AF previously used for this purpose, especially at high frequencies typically used in communication systems. Secondly, we propose a two-step (coarse-to-fine) localization technique. The second step provides refined spatial sampling of the AF in the vicinity of its maximum found on the coarse space grid covering an area of interest (in range and depth), computed at the first step. This technique allows high localization accuracy and reduction in complexity and memory storage, compared to the single step localization. Thirdly, we propose a joint refinement of the AF around several maxima to reduce outliers. For validation of the proposed techniques, we run numerical experiments in different UWA environments, with different parameters for the spatial sampling, number of transmit antennas and different accuracy for the estimation of the acoustic channel response. </p>

Published: July 2022

<p> In this paper, the diversity order (DO) and the diversity measure (DM) of multiple-input multiple-output (MIMO) antennas in generic single-user, multi-user and massive MIMO wireless communications are calculated for several practical case studies. These performance metrics are calculated from the antenna correlation coefficient (ACC) matrix. The DO is calculated from the rank of the ACC matrix, and the DM is obtained from the trace and Frobenius norm of the ACC matrix. Numerical results are provided. In particular, it is shown that though the DM is always less than the DO, it incorporates the effect of antenna correlation on the diversity gain in a better way.

Online mouse cursor trajectories distinguish phonological activation by linguistic and nonlinguistic sounds
Authors: Kukona Anuenue , Jordan Adrian 
Published: July 2022

AbstractFour online mouse cursor tracking experiments (totalN= 208) examined the activation of phonological representations by linguistic and nonlinguistic auditory stimuli. Participants hearing spoken words (e.g., “bell”) produced less direct mouse cursor trajectories toward corresponding pictures or text when visual arrays also included phonologically related competitors (e.g., belt) as compared with unrelated distractors (e.g., hose), but no such phonological competition was observed during environmental sounds (e.g., the ring of a bell). While important similarities have been observed between spoken words and environmental sounds, these experiments provide novel mouse cursor evidence that environmental sounds directly activate conceptual knowledge without needing to engage linguistic knowledge, contrasting with spoken words. Implications for theories of conceptual knowledge are discussed.
Patchy Nightside Clouds on Ultra-hot Jupiters: General Circulation Model Simulations with Radiatively Active Cloud Tracers
Authors: Komacek Thaddeus D. , Tan Xianyu , Gao Peter , Lee Elspeth K. H. 
Published: July 2022

Abstract
The atmospheres of ultra-hot Jupiters have been characterized in detail through recent phase curve and low- and high-resolution emission and transmission spectroscopic observations. Previous numerical studies have analyzed the effect of the localized recombination of hydrogen on the atmospheric dynamics and heat transport of ultra-hot Jupiters, finding that hydrogen dissociation and recombination lead to a reduction in the day-to-night contrasts of ultra-hot Jupiters relative to previous expectations. In this work, we add to previous efforts by also considering the localized condensation of clouds in the atmospheres of ultra-hot Jupiters, their resulting transport by the atmospheric circulation, and the radiative feedback of clouds on the atmospheric dynamics. To do so, we include radiatively active cloud tracers into the existing MITgcm framework for simulating the atmospheric dynamics of ultra-hot Jupiters. We take cloud condensate properties appropriate for the high-temperature condensate corundum from CARMA cloud microphysics models. We conduct a suite of general circulation model (GCM) simulations with varying cloud microphysical and radiative properties, and we find that partial cloud coverage is a ubiquitous outcome of our simulations. This patchy cloud distribution is inherently set by atmospheric dynamics in addition to equilibrium cloud condensation, and causes a cloud greenhouse effect that warms the atmosphere below the cloud deck. Nightside clouds are further sequestered at depth due to a dynamically induced high-altitude thermal inversion. We post-process our GCMs with the Monte Carlo radiative transfer code gCMCRT and find that the patchy clouds on ultra-hot Jupiters do not significantly impact transmission spectra but can affect their phase-dependent emission spectra.
Evolution of the Heliotail Lobes over a Solar Cycle as Measured by IBEX

Published: July 2022

Abstract
Energetic neutral atom (ENA) measurements by IBEX reveal that the heliotail comprises an energy-dependent multilobe structure. We examine the heliotail evolution over 11 yr of IBEX observations covering a full solar cycle (SC). We find the following: (1) The heliotail structure persists over the entire SC, comprising three ENA-enhanced and two ENA-suppressed lobes. (2) Lobe sizes and locations are generally stable but exhibit variations in ENA fluxes driven by the SC. (3) Lobe centers follow a cyclic behavior over multiple SC phases, indicating direct signatures of slow and fast solar wind (SW) interactions in the inner heliosheath (IHS). (4) The tilted plane passing through the port–starboard lobes’ centers oscillates in latitude but maintains its tilt from the ecliptic plane, likely a consequence of the interstellar magnetic field draping around the heliosphere. (5) The transition of the central heliotail from a single lobe at ∼1.1 keV to two lobes above ∼2 keV is SC-dependent and directly reflects the IHS plasma properties, i.e., when ENA fluxes from fast SW from the polar coronal holes change over time. (6) The central lobe exhibits a substructure that is enhanced and offset from the downwind direction, possibly indicating an asymmetric ENA emission or an asymmetry in the parent plasma distribution. These results reveal the general stability of the heliotail structure over time and distinct variations in individual lobes’ properties in relation to the SC phases. Furthermore, results show the effects of multiple SC phases in the tail, reflecting different ENA travel times and source histories.

Abstract
We performed photometric observations of the binary near-Earth asteroid (65803) Didymos in support of the Double Asteroid Redirection Test (DART) mission that will test the Kinetic Impactor technology for diverting dangerous asteroids. It will hit the Didymos secondary, called Dimorphos, on 2022 September 26. We observed Didymos with 11 telescopes with diameters from 3.5 to 10.4 m during four apparitions in 2015–2021, obtaining data with rms residuals from 0.006 to 0.030 mag. We analyzed the light-curve data and decomposed them into the primary rotational and secondary orbital light curves. We detected 37 mutual eclipse/occultation events between the binary system components. The data presented here, in combination with 18 mutual events detected in 2003, provide the basis for modeling the Dimorphos orbit around the Didymos primary. The orbit modeling is discussed in detail by Scheirich & Pravec and Naidu et al. The primary light curves were complex, showing multiple extrema on some epochs. They suggest a presence of complex topography on the primary’s surface that is apparent in specific viewing/illumination geometries; the primary shape model by Naidu et al. (Icarus 348, 113777, 2020) needs to be refined. The secondary rotational light-curve data were limited and did not provide a clear solution for the rotation period and equatorial elongation of Dimorphos. We define the requirements for observations of the secondary light curve to provide the needed information on Dimorphos’s rotation and elongation when Didymos is bright in 2022 July–September before the DART impact.

Uranus’s moon Miranda has a complex surface reflecting multiple episodes of activity. We estimated the heat flux near Inverness Corona, the youngest terrain on Miranda (

Ma), to gain insight into recent endogenic resurfacing. We modeled flexure associated with Argier Rupes, which separates Inverness from the Cratered Terrain. Our results indicate an elastic thickness of 2.2–3.1 km and a heat flux of 35–140 mW m−2 in this region, assuming Miranda’s lithosphere is composed of pure H2O ice without porosity. Because the formation of the bounding flexure that we analyzed followed the formation of Argier Rupes, our results indicate that Miranda experienced high heat flux in the past

Ma. These results are also consistent with heating from a past resonance, possibly an Ariel–Umbriel 5:3 mean motion resonance, estimated to have generated heat fluxes >100 mW m−2 on Miranda. However, if Miranda instead has a porous lithosphere, our heat flux estimates are lower: 34–135 mW m−2 for 5% porosity, 29–114 mW m−2 for 15% porosity, and 20–81 mW m−2 for 25% porosity. Alternatively, if Miranda’s lithosphere includes NH3-hydrates, then our are estimates are even lower, 7–56 mW m−2 without porosity. These estimates decrease further when assuming NH3-hydrates and porosity: 7–54 mW m−2 for 5% porosity, 6–46 mW m−2 for 15% porosity, and 4–32 mW m−2 for 25% porosity. Better constraints on Miranda’s heat fluxes require more information on its ice shell properties.
Camino Francés y urbanismo en la Galicia medieval: el caso del antiguo burgo de Triacastela
Authors: Valdés Blanco-Rajoy Rosario 
Published: July 2022

Santa María de Vilavella constituye el caso poco conocido de un burgo del Camino Francés, que surgió al abrigo de un monasterio altomedieval relacionado con la acogida de peregrinos. Tras alcanzar en el siglo XII un cierto grado de desarrollo asociado al trasiego del Camino, comenzó su decadencia como centro viario y comercial cuando en las primeras décadas del siglo XIII el rey Alfonso IX de León creó la nueva puebla de Triacastela, trasladando la población a otro emplazamiento más ventajoso enclavado sobre una encrucijada de la misma ruta. Mientras que la nueva fundación se afianzó con éxito como cabecera territorial, constituyendo un núcleo configurado por el eje viario y por la cerca que lo defendía, el antiguo burgo de Santa María mantuvo su caserío agrupado al pie de la antigua iglesia monasterial, evolucionando como una aldea más del ámbito rural gallego, toda vez que su principal dedicación quedó revertida a la explotación de los recursos agropecuarios.

Despois de alcanzar certo grao de desenvolvemento no século XII, asociado ao tránsito do Camiño de Santiago, o seu declive como centro comercial e viario comezou cando o rei Afonso IX de León estableceu a nova entidade de poboación de Triacastela nas primeiras décadas do século XIII nunha encrucillada xacobea próxima. Entrementres Triacastela se afianzaba coma un núcleo camiñeiro e amurallado, cabeceira territorial, o antigo burgo de Santa María mantiña o seu casarío agrupado na contorna da antiga igrexa monástica, evolucionando como unha aldea máis da paisaxe rural galega, centrada na explotación primaria dos recursos agropecuarios.
Santa Ana en la Edad Media. Iconografía y devoción en la catedral de Mondoñedo
Authors: Méndez-Sánchez Almudena María 
Published: July 2022

En el registro hagiográfico de la cristiandad, el estatus conferido a santa Ana se debe a su condición de madre de la Virgen María. El interés de la cristiandad hacia su figura, debido a su creciente devoción en el occidente medieval, se fundamenta en la lectura de los evangelios apócrifos y los comentarios de teólogos medievales acerca de su vida, entre los que destaca la exégesis realizada por Jacobo de la Vorágine en la Leyenda Dorada. En el contexto hispánico este estudio analiza cómo esta devoción se manifiesta en la producción artística del territorio de la diócesis mindoniense, entre los siglos XV y XVI, conformándose como centro devocional la catedral de Mondoñedo. En ella se conserva un ciclo de pinturas murales en el que se inserta una representación de santa Ana Triple, que constituye un ejemplo de la devoción local hacia la madre de la Virgen, cuya relevancia se estudia con relación al programa pictórico catedralicio.

La consolidación de las élites urbanas a finales de la Edad Media: estudio histórico-diplomático del mayorazgo del jerezano Gonzalo Pérez de Gallegos
Authors: Jiménez López de Eguileta Javier E. , Ruiz Pilares Enrique J. 
Published: July 2022

Las ciudades andaluzas bajomedievales estuvieron gobernadas prácticamente desde la conquista del valle del Guadalquivir en el siglo XIII por un reducido grupo de familias vinculadas a la vida militar fronteriza, a las actividades agropecuarias y al servicio de la monarquía y a la alta nobleza. La institución del regimiento por Alfonso XI sancionó legalmente el sistema oligárquico, aunque el proceso de cierre y consolidación de la élite concejil no se hizo efectivo hasta la segunda mitad del siglo XV. El traspaso cuasi hereditario de los oficios concejiles, la asunción de los valores aristocráticos y su estilo de vida, la institución de mayorazgos y, ya bien entrado el siglo XVI, el reconocimiento jurídico de la hidalguía, fueron las últimas etapas de este largo proceso de ascenso y consolidación política. El linaje Gallegos de Jerez de la Frontera es un buen ejemplo de ello. Llegados desde tierras gallegas como pobladores en 1269, dos siglos después se habían consolidado dentro del grupo dirigente. A comienzos del siglo XVI, Gonzalo Pérez de Gallegos servía a los duques de Medinaceli, pertenecía al regimiento urbano y había participado activamente en la vida fronteriza. Cercano a su muerte y gracias a la licencia regia concedida por Carlos I, quiso garantizar en 1527 la posición alcanzada por su linaje instituyendo su mayorazgo ante un escribano público de la ciudad.

A institución do rexemento por Afonso XI sancionou legalmente o sistema oligárquico, aínda que o proceso de peche e consolidación da elite concellil non se completou ata a segunda metade do século XV. O traspaso case hereditario dos oficios dos concellos, a asunción dos valores aristocráticos e o seu estilo de vida, a institución de morgados, e xa no século XVI, o recoñecemento xurídico da fidalguía, foron as derradeiras etapas deste longo proceso de ascenso e consolidación política. A liñaxe Gallegos de Jerez de la Frontera é un bo exemplo deste fenómeno. Procedentes de terras galegas como poboadores en 1269, dous séculos despois xa estaban consolidados dentro do grupo dirixente. A comezos do século XVI, Gonzalo Pérez de Gallegos traballaba ás ordes dos duques de Medinaceli, pertencía ao rexemento urbano e participara de xeito activo na vida de fronteira. Estando preto da súa morte e grazas á licenza rexia que lle fora outorgada por Carlos I, Gonzalo Pérez quixo garantir en 1527 a posición acadada pola súa liñaxe instituíndo o seu morgado diante dun escribán público da cidade.
La Santa Cena del colegio jesuítico de Monterrei (Ourense). Atribución, fuentes y difusión de un grabado de Johann Sadeler I y Peter de Witte

Published: July 2022

La Santa Cena del Castillo de Monterrei, de excepcional tema y dimensiones en el arte gallego de la Edad Moderna, apenas ha sido estudiada. Combinando la historia cultural y el estudio formal e iconográfico, analizamos la pintura con tres hipótesis de partida: su procedencia de una fundación jesuítica, su vinculación con Juan A. García de Bouzas y el uso de un modelo grabado flamenco. La adscripción al Colegio de Monterrei se ve respaldada por su IHS y la significación del tema para la Compañía. Además, exponemos su probable presencia en el “Museo de Pinturas de Orense” (1845-1852). De la autoría de Bouzas o su taller hay numerosos indicios: desde otros trabajos para los jesuitas hasta similitudes formales y técnicas con obras propias y de su maestro Luca Giordano. No obstante, la falta de documentación nos obliga a proponer una mera atribución. Por último, localizamos la principal fuente artística de la obra: un grabado de Johann Sadeler I basado en una pintura del ítalo-flamenco Peter de Witte que encabeza una dispersa familia artística de la que por primera vez identificamos o relacionamos algunas copias.
