Compact spoof surface plasmonic waveguide with controllable cutoff frequency and wide stop band

Published: January 2021

Abstract
To adjust the transmission band while keeping the width of a spoof surface plasmon polariton (SSPP) waveguide unchanged, periodic cells with T-shaped conductor branches on both sides are used. By controlling the top lateral strips of branches, the adjustable range of cutoff frequencies can reach approximately 3.5 GHz. Thus, compromised regulation of the field confinement and transmission loss is easily achieved, improving the transmission performance of SSPP modes. By loading open conductor rings onto T-shaped branches to construct a split ring resonator (SRR), a band-rejection filter is realized. When multiple SRRs with gradient lengths are loaded onto one side of the SSPP waveguide, a broad stop band with a relative bandwidth of 18% is achieved. The proposed structures are also advantageous for the miniaturization of microwave circuits.
Terahertz coherent oscillator integrated with slot-ring antenna using two resonant tunneling diodes

Published: January 2021

Abstract
The development of compact, high-output-power electronic terahertz sources will benefit from coherent combination of power from multiple oscillators. Mutual coupling for power combining and linewidth narrowing generally requires additional, potentially lossy coupling structures that limit array scalability. To address this limitation, two resonant tunneling diode (RTD) oscillators integrated within a single slot-ring antenna are herein proposed. They employ an innate phase-locking mechanism, thereby realizing mutual-coupling and radiation simultaneously. The proposed double-RTD device is experimentally found to demonstrate a single-peak oscillation at 354 GHz with narrow linewidth (2 MHz), higher output power (31 μW), and linearly polarized, unimodal radiation pattern.

Представлены результаты исследования электрохимической активности биорезорбируемого магниевого сплава Mg–0,8Ca в среде для культивирования клеток млекопитающих – minimum essential medium (MEM). Наиболее высокая коррозионная активность сплава выявлена на начальной стадии выдержки в растворе (первые 12 мин). Установлен механизм коррозионной деградации материала, заключающийся в инициировании разрушения на границах зерен вследствие образования микрогальванических пар. Это объясняется присутствием в сплаве интерметаллидной фазы Mg2Ca, являющейся анодной по отношению к α-матрице магния. Предложена модель формирования слоя продуктов коррозии на поверхности сплава при его выдержке в MEM.
The paper presents results of study of electrochemical activity of the Mg–0.8Ca bioresorbable alloy in a medium for the cultivation of mammalian cells – the minimum essential medium (MEM). The highest corrosion activity of the alloy was revealed at the initial stage of exposure in the solution (for the first 12 minutes). The mechanism of corrosion degradation of material has been determined and it is characterized with initiation of the destruction at grain boundaries caused by the formation of micro-galvanic couples. It is explained by the presence of Mg2Ca intermetallic phase which is anodic against α- magnesium matrix. A model of formation of corrosion products layer on alloy`s surface during the exposition in MEM solution is proposed.

Published: January 2021

Рассматриваются концепция и реализация контрольно-аварийной системы (КАС), которая направлена на повышение живучести автономных необитаемых подводных аппаратов (АНПА) различного класса и назначения. Задача повышения живучести АНПА решается одновременно по нескольким направлениям: дублирование программных и аппаратных средств, а также обеспечение их взаимного согласованного (не противоречивого) функционирования. КАС создана на базе иерархической декомпозиции решаемых задач и включает в себя несколько уровней программного обеспечения, а также аппаратную часть. Программная часть КАС выполняет контроль целостности программного обеспечения, предстартовую диагностику, мониторинг ошибок и аварий. Аппаратная часть КАС обеспечивает возможность обнаружения и подъема АНПА в случае выхода из строя его вычислительной системы. Ключевой особенностью предлагаемого подхода является «относительно независимое» поведение систем в различных режимах работы (как штатных, так и аварийных), а также способность КАС в максимальном объеме выполнять заложенную программу-задание (миссию). Рассматриваются различные сценарии поведения АНПА во время возникновения нештатных ситуаций.
The work considers the concept and implementation of an emergency control system (ECS) to increase the survivability of autonomous underwater vehicles (AUV) of different types and functionality. The task of raising the AUV survivability can be solved in several ways: dual redundancy of software and hardware means and providing their mutual coherent (consistent) functioning. ECS is based on a hierarchal decomposition of solving tasks and includes several software layers and hardware components. The ECS software component controls the software's integrity, prelaunch diagnostic, errors, and emergency monitoring. The ECS hardware component provides capabilities of positioning and emersion of AUV in case of its computational system malfunction. The key feature of the proposed approach is the "relatively independent" behavior of the systems in different operational modes (both routine and emergency) and the capability of the ECS to perform the predetermined task (mission) to the maximum extent. Different scenarios of AUV behavior in emergencies are considered.

Hautatahdossa on lain mukaan kyse vainajan autonomian ja katsomusten kunnioittamisesta. Tämä artikkeli analysoi läheisensä menettäneiden kertomuksia hautatahdosta ja siitä, miten he ovat pyrkineet huomioimaan vainajan tahdon hautajaisten suunnittelussa ja hautauspaikan valinnassa. Artikkelin aineisto muodostuu kolmentoista surevan läheisen haastatteluista, jotka on analysoitu temaattisella sapluuna-analyysillä. Tulokset osoittavat, että osassa tapauksista vainaja oli selkeästi ilmaissut toiveensa hautaussuunnitelmista, mutta osassa tapauksista kyse oli oletetun hautatahdon ilmaisuista. Katsomukset vaikuttivat vainajan hautatoiveisiin erityisesti silloin kun hänellä oli ollut selvä uskonnollinen tai ei-uskonnollinen vakaumus. Vainajan, surevan läheisen ja muiden läheisten relaatioilla oli iso merkitys vainajan hautatahdon seuraamisessa. Tutkimuksemme osoitti, että uusperhetilanne hankaloitti vainajan hautatahdon noudattamista erityisesti niissä tilanteissa, joissa läheisillä oli erilaisia tulkintoja vainajan toiveista. Mitä selvemmin vainaja on ilmaissut toiveensa hautausrituaalista, hautatavasta ja hautapaikasta läheisilleen, sitä helpompi hautajaiset on järjestää. Tämä säästää läheisiä turhilta riidoilta ja mielipahalta.

The road to long-term memory: Top-down attention is more effective than bottom-up attention for forming long-term memories
Authors: Sasin Edyta , Fougnie Daryl 
Published: January 2021

AbstractDoes the strength of representations in long-term memory (LTM) depend on which type of attention is engaged? We tested participants’ memory for objects seen during visual search. We compared implicit memory for two types of objects—related-context nontargets that grabbed attention because they matched the target defining feature (i.e., color; top-down attention) and salient distractors that captured attention only because they were perceptually distracting (bottom-up attention). In Experiment 1, the salient distractor flickered, while in Experiment 2, the luminance of the salient distractor was alternated. Critically, salient and related-context nontargets produced equivalent attentional capture, yet related-context nontargets were remembered far better than salient distractors (and salient distractors were not remembered better than unrelated distractors). These results suggest that LTM depends not only on the amount of attention but also on the type of attention. Specifically, top-down attention is more effective in promoting the formation of memory traces than bottom-up attention.

Published: January 2021

Abstract
The mergers of binary neutron stars, as well as black hole–neutron star systems, are expected to produce an electromagnetic counterpart that can be analyzed to infer the element synthesis that occurred in these events. We investigate one source of uncertainties pertinent to lanthanide-rich outflows: the nuclear inputs to rapid neutron capture nucleosynthesis calculations. We begin by examining 32 different combinations of nuclear inputs: eight mass models, two types of spontaneous fission rates, and two types of fission daughter product distributions. We find that such nuclear physics uncertainties typically generate at least one order of magnitude uncertainty in key quantities such as the nuclear heating (one and a half orders of magnitude at 1 day post-merger), the bolometric luminosity (one order of magnitude at 5 days post-merger), and the inferred mass of material from the bolometric luminosity (factor of 8 when considering the 8–10 day region). Since particular nuclear processes are critical for determining the electromagnetic signal, we provide tables of key nuclei undergoing β-decay, α-decay, and spontaneous fission important for heating at different times, identifying decays that are common among the many nuclear input combinations.
The Effects of Biconical Outflows on Lyα Escape from Green Peas
Authors: Carr Cody , Scarlata Claudia , Henry Alaina , Panagia Nino 
Published: January 2021

Abstract
We analyze the spectra of 10 Green Pea galaxies, previously studied by Henry et al., using a semi-analytical line transfer model to interpret emission and absorption features observed in UV galactic spectra. We focus our analysis on various ionization states of silicon, associated with the cool (∼104 K) and warm (∼105 K) gas. By analyzing low-ionization lines, we study the relationships between the distribution and kinematics of the outflowing H i gas and the observed Lyα escape fraction,

, as well as the Lyα emission peak separation, Δpeak. We find that outflow geometries that leave a portion of the source uncovered along the line of sight create the best conditions for Lyα escape and have narrow peak separations, while geometries that block the observer’s view of the source create the worst conditions for Lyα escape and have large peak separations. To isolate the effects of outflow kinematics, we restrict our testing set to galaxies with spherical outflows and find that

and the Lyα luminosity both increase with the extent of the galactic winds. A simple estimate suggests that the collisional excitation of neutral hydrogen by free electrons in the cool gas of the winds can account for the Lyα luminosity observed in these objects. Finally, we speculate on the relationship between outflows and the escape of ionizing radiation from the circumgalactic medium.
Evolution of Three-dimensional Coherent Structures in Hall Magnetohydrodynamics
Authors: Bora K. , Bhattacharyya R. , Smolarkiewicz P. K. 
Published: January 2021

Abstract
This work extends the computational model EULAG-MHD to include Hall magnetohydrodynamics (HMHD)—important to explore physical systems undergoing fast magnetic reconnection at the order of the ion inertial length scale. Examples include solar transients along with reconnections in magnetosphere, magnetotail, and laboratory plasmas. The paper documents the results of two distinct sets of implicit large-eddy simulations in the presence and absence of the Hall forcing term, initiated with an unidirectional sinusoidal magnetic field. The HMHD simulation while benchmarking the code also emphasizes the complexity of three-dimensional (3D) evolution over its two-dimensional counterpart. The magnetic reconnections onset significantly earlier in HMHD. Importantly, the magnetic field generated by the Hall term breaks any inherent symmetry, ultimately making the evolution 3D. The resulting 3D reconnections develop magnetic flux ropes (MFRs) and magnetic flux tubes. Projected on the reconnection plane, the ropes and tubes appear as magnetic islands, which later break into secondary islands, and finally coalesce to generate an X-type neutral point. These findings are in agreement with the theory and contemporary simulations of HMHD, and thus verify our extension of the EULAG-MHD model. The second set explores the influence of the Hall forcing on generation and ascend of an MFR from sheared magnetic arcades—a novel scenario instructive in understanding the coronal transients. The rope evolves through intermediate complex structures, ultimately breaking locally because of reconnections. Interestingly, the breakage occurs earlier in the presence of the Hall term, signifying faster dynamics leading to magnetic topology favorable for reconnections.
From Supernova to Supernova Remnant: Comparison of Thermonuclear Explosion Models

Abstract
Progress in the three-dimensional modeling of supernovae (SNe) prompts us to revisit the supernova remnant (SNR) phase. We continue our study of the imprint of a thermonuclear explosion on the SNR it produces, which we started with a delayed detonation model of a Chandrasekhar-mass white dwarf. Here we compare two different types of explosion models, each with two variants: two delayed detonation models (N100ddt, N5ddt) and two pure deflagration models (N100def, N5def), where the N number parameterizes the ignition. The output of each SN simulation is used as input to an SNR simulation carried on until 500 yr after the explosion. While all SNR models become more spherical over time and overall display the theoretical structure expected for a young SNR, clear differences are visible among the models, depending on the geometry of the ignition and on the presence or not of detonation fronts. Compared to N100 models, N5 models have a strong dipole component and produce asymmetric remnants. N5def produces a regular-looking, but offset remnant, while N5ddt produces a two-sided remnant. Pure deflagration models exhibit specific traits: a central overdensity, because of the incomplete explosion, and a network of seam lines across the surface, boundaries between burning cells. Signatures from the SN dominate the morphology of the SNR up to 100–300 yr after the explosion, depending on the model, and are still measurable at 500 yr, which may provide a way of testing explosion models.
Systematic Study of AGN Clumpy Tori with Broadband X-Ray Spectroscopy: Updated Unified Picture of AGN Structure

Published: January 2021

Abstract
We present the results of a systematic, broadband X-ray spectral analysis of nearby active galactic nuclei (AGNs) with the X-ray clumpy torus model (XCLUMPY). By adding 16 AGNs newly analyzed in this paper, we study a total of 28 AGNs, including unabsorbed and absorbed AGNs taken from Ichikawa et al. and García-Bernete et al. This is the largest sample whose X-ray and infrared spectra are analyzed by the clumpy torus models XCLUMPY and CLUMPY, respectively. The relation between the Eddington ratio and the torus covering factor determined from the X-ray torus parameters of each object follows the trend found by Ricci et al. based on a statistical analysis. We confirm the results by Tanimoto et al. that (1) the torus angular widths determined by the infrared data are larger than those by the X-ray data and (2) the ratios of hydrogen column density to V-band extinction (N
H/A

V
) along the line of sight in obscured AGNs are similar to the Galactic value, on average. Unobscured AGNs show apparently smaller line-of-sight N
H/A

V
ratios than the Galactic one. Our findings can be well explained by an updated unified picture of AGN structure including a dusty torus, dusty polar outflows, and dust-free gas, where the inclination determines the X-ray and optical classifications and observed torus properties in the X-ray and infrared bands.
