Abstract
Random-access multi-focus manipulation of multiple light beams at high speed can accelerate various important processes, such as laser material processing and imaging, and benefit semiconductor manufacturing and biomedical research. In this letter, we propose random-access multi-focus manipulation through superpixel-encoding wavefront engineering (RMM-SWE). This method simultaneously manipulates 25 independent focal spots at a rate as high as 23 kHz, which considerably increased the efficiency of scanning over irregular, complicated paths. We applied RMM-SWE to direct laser writing and showed that RMM-SWE holds great potential for the applications requiring multi-focus manipulation with high scanning speed, flexibility, and spatial resolution.
Computational Processes for General Intelligence

Published: October 2022

<p>The ‘brain-mind-intelligence’ structure may be considered analogous to a ‘computer-operating system (OS)-application’ construct. Software development would be far more difficult without the benefit of abstractions like file and memory handles, and graphical user interfaces, implemented in operating systems. The easy access to application-level semantics, provided by the infrastructure of the OS, simplifies application development. Abstractions can play a similar role in producing intelligent systems. The power of abstractions may be determined by their ability to unify the treatment of several types of higher concepts. Unifying various concepts in the domain of intelligence, such as problems, solutions, objects, and emotions, through abstractions will be of immense value. This paper shows how ‘higher-level perceptions’ could be used to serve this objective and construct an OS-like infrastructure. With the infrastructure in place, ordinary software objects developed and deployed using standard methods, become accessible using the semantics provided by the infrastructure. Now, after brief training exercises, the objects would be available for intelligent use. The focus, therefore, is on the design of the infrastructure that could play a mind-like role in humans. </p>
<p>The resulting model is then evaluated in terms of features against criteria set forth independently, by Newell, Sun, Vernon, and others. In addition, a new measure of intelligence introduced in this paper is used to compare the proposed modeling method with some of the major methods developed over the years.</p>

Published: October 2022

Рассматривается задача оптимизации геометрических параметров двухшарнирных рам на основе критерия минимума потенциальной энергии упругой деформации. Варьируемыми параметрами являются эксцентриситеты шарнирных опор. Стержни рамы имеют неоднородную структуру и продольное геометрическое профилирование. В качестве примера рассмотрена оптимизация рамы со стойками линейно-переменной высоты сечения. Показаны графики потенциальной энергии деформации для рам различной высоты. Минимумы на графиках дают значение оптимального эксцентриситета, который в зависимости от степени трапецеидальности стоек может иметь различные значения, в том числе - по знаку, который свидетельствует о смещении опорного шарнира внутрь или наружу рамы. Произведено сравнение эпюр изгибающих моментов в раме с оптимальными и нулевыми эксцентриситетами. Изложены методика и расчетные соотношения для компонент напряжений и условий прочности, необходимых для выполнения проектного этапа решения задачи определения абсолютных значений геометрических параметров - размеров сечений рамы.
The problem of optimizing the geometrical parameters of double-hinged frames based on the criterion of minimum potential energy of elastic deformation is considered. Variable parameters are the eccentricities of the hinged supports. The frame rods have a heterogeneous structure and longitudinal geometric profiling. As an example, the optimization of a frame with racks of a linearly variable section height is considered. Graphs of potential strain energy for frames of various heights are shown. The minimums on the graphs give the value of the optimal eccentricity, which, depending on the degree of trapezoidality of the racks, can have different values, including the sign, which indicates the displacement of the support hinge in or out of the frame. The diagrams of bending moments in the frame are compared with optimal and zero eccentricities. The technique and calculation ratios for the stress components and strength conditions necessary to perform the design stage of solving the problem of determining the absolute values of geometric parameters - the dimensions of the frame sections are outlined.

The performed studies on the calculation of stress-strain state of load-bearing systems of transport structures under the influence of solar radiation are summarized. Finite element models of two types of superstructures have been developed, including layers of pavement with the possibility of taking into account the uneven effects of solar radiation. The calculation was performed without the assumption of an absolutely rigid connection of the main beam and the superstructure plate. The analysis of the results of a series of full-scale measurements of the temperature fields of the superstructure elements and the stress-strain state of the main beams in various cases of exposure to solar radiation is carried out. The influence of uneven heating on the nature of the stress-strain state of the superstructure is studied and the results of instrumental measurements and numerical calculations are verified. The temperature limits of the application of the developed methodology are determined and recommendations for practical calculations are prepared.

Six of one, half dozen of the other: Suboptimal prioritizing for equal and unequal alternatives
Authors: James Warren , Hunt Amelia R. , Clarke Alasdair D. F. 
Published: October 2022

AbstractIt is possible to accomplish multiple goals when available resources are abundant, but when the tasks are difficult and resources are limited, it is better to focus on one task and complete it successfully than to divide your efforts and fail on both. Previous research has shown that people rarely apply this logic when faced with prioritizing dilemmas. The pairs of tasks in previous research had equal utility, which according to some models, can disrupt decision-making. We investigated whether the equivalence of two tasks contributes to suboptimal decisions about how to prioritize them. If so, removing or manipulating the arbitrary nature of the decision between options should facilitate optimal decisions about whether to focus effort on one goal or divide effort over two. Across all three experiments, however, participants did not appropriately adjust their decisions with task difficulty. The only condition in which participants adopted a strategy that approached optimal was when they had voluntarily placed more reward on one task over the other. For the task that was more rewarded, choices were modified more effectively with task difficulty. However, participants were more likely to choose to distribute rewards equally than unequally. The results demonstrate that situations involving choices between options with equal utility are not avoided and are even slightly preferred over unequal options, despite unequal options having larger potential gains and leading to more effective prioritizing strategies.

Abstract
Gliese 86 is a nearby K dwarf hosting a giant planet on a ≈16 day orbit and an outer white dwarf companion on a ≈century-long orbit. In this study we combine radial velocity data (including new measurements spanning more than a decade) with high angular resolution imaging and absolute astrometry from Hipparcos and Gaia to measure the current orbits and masses of both companions. We then simulate the evolution of the Gl 86 system to constrain its primordial orbit when both stars were on the main sequence; the closest approach between the two stars was then about 9 au. Such a close separation limited the size of the protoplanetary disk of Gl 86 A and dynamically hindered the formation of the giant planet around it. Our measurements of Gl 86 B and Gl 86 Ab’s orbits reveal Gl 86 as a system in which giant planet formation took place in a disk truncated at ≈2 au. Such a disk would be just big enough to harbor the dust mass and total mass needed to assemble Gl 86 Ab’s core and envelope, assuming a high disk accretion rate and a low viscosity. Inefficient accretion of the disk onto Gl 86 Ab, however, would require a disk massive enough to approach the Toomre stability limit at its outer truncation radius. The orbital architecture of the Gl 86 system shows that giant planets can form even in severely truncated disks and provides an important benchmark for planet formation theory.

Abstract
We report 23 stars having Galactocentric velocities larger than 450 km s−1 in the final data release of the APOGEE survey. This sample was generated using space velocities derived by complementing the high-quality radial velocities from the APOGEE project in Sloan Digital Sky Survey’s Data Release 17 (DR17) with distances and proper motions from Gaia early Data Release 3 (eDR3). We analyze the observed kinematics and derived dynamics of these stars, considering different potential models for the Galaxy. We find that three stars could be unbound depending on the adopted potential, but in general all of the stars show typical kinematics of halo stars. The APOGEE DR17 spectroscopic results and Gaia eDR3 photometry are used to assess the stellar parameters and chemical properties of the stars. All of the stars belong to the red giant branch, and, in general, they follow the abundance pattern of typical halo stars. There are a few exceptions that would deserve further analysis through high-resolution spectroscopy. In particular, we identify a high-velocity Carbon-Enhanced Metal-Poor star, with a Galactocentric velocity of 482 km s−1. We do not confirm any hypervelocity star in the sample, but this result is very sensitive to the adopted distances and less sensitive to the Galactic potential.
Scattered Light in the Hinode/EIS and SDO/AIA Instruments Measured from the 2012 Venus Transit
Authors: Young Peter R. , Viall Nicholeen M. 
Published: October 2022

Abstract
Observations from the 2012 transit of Venus are used to derive empirical formulae for long- and short-range scattered light at locations on the solar disk observed by the Hinode Extreme ultraviolet Imaging Spectrometer (EIS) and the Solar Dynamics Observatory Atmospheric Imaging Assembly (AIA) instruments. Long-range scattered light comes from the entire solar disk, while short-range scattered light is considered to come from a region within 50″ of the region of interest. The formulae were derived from the Fe xii 195.12 Å emission line observed by EIS and the AIA 193 Å channel. A study of the weaker Fe xiv 274.20 Å line during the transit and a comparison of scattering in the AIA 193 Å and 304 Å channels suggests the EIS scattering formula applies to other emission lines in the EIS wavebands. Both formulae should be valid in regions of fairly uniform emission such as coronal holes and quiet Sun, but may be less accurate for faint areas close (around 100″) to bright active regions. The formula for EIS is used to estimate the scattered light component of Fe xii
λ195.12 for seven on-disk coronal holes observed between 2010 and 2018. Scattered light contributions of 56%–100% are found, suggesting that these features are dominated by scattered light, consistent with earlier work of Wendeln & Landi. Emission lines from the S x and Si x ions—formed at the same temperature as Fe xii and often used to derive the first ionization potential bias from EIS data—are also expected to be dominated by scattered light in coronal holes.
Comparing the Performance of a Solar Wind Model from the Sun to 1 au Using Real and Synthetic Magnetograms

Published: October 2022

Abstract
The input of the solar wind models plays a significant role in accurate solar wind predictions at 1 au. This work introduces a synthetic magnetogram produced from a dynamo model as an input for magnetohydrodynamics simulations. We perform a quantitative study that compares the space weather modeling framework (SWMF) results for the observed and synthetic solar magnetogram input. For each case, we compare the results for extreme ultraviolet images and extract the simulation data along the Earth trajectory to compare with in situ observations. We initialize the SWMF using the real and synthetic magnetograms for a set of Carrington rotations within solar cycles 23 and 24. Our results help quantify the ability of dynamo models to be used as input to solar wind models and thus provide predictions for the solar wind at 1 au.
Shocks in the Outflow of the RS Oph 2021 Eruption Observed with X-Ray Gratings

Abstract
The 2021 outburst of the symbiotic recurrent nova RS Oph was observed with the Chandra High Energy Transmission Gratings (HETG) on day 18 after optical maximum and with XMM-Newton and its Reflection Grating Spectrographs (RGS) on day 21, before the supersoft X-ray source emerged and when the emission was due to shocked ejecta. The absorbed flux in the HETG 1.3–31 Å range was 2.6 × 10−10 erg cm−2 s−1, three orders of magnitude lower than the γ-ray flux measured on the same date. The spectra are well fitted with two components of thermal plasma in collisional ionization equilibrium, one at a temperature ≃ 0.75 keV and the other at a temperature in the 2.5–3.4 keV range. With the RGS we measured an average flux of 1.53 × 10−10 erg cm−2 s−1 in the 5–35 Å range, but the flux in the continuum and especially in the lines in the 23–35 Å range decreased during the 50 ks RGS exposure by almost 10%, indicating short-term variability on a timescale of hours. The RGS spectrum can be fitted with three thermal components, respectively at plasma temperatures between 70 and 150 eV, 0.64 keV, and 2.4 keV. The post-maximum epochs of the exposures fall between those of two grating spectra observed in the 2006 eruption on days 14 and 26: they are consistent with a similar spectral evolution, but in 2021 cooling seems to have been more rapid. Iron is depleted in the ejecta with respect to solar values, while nitrogen is enhanced.
