description: Under visual guidance, subjects reached for and manipulated an object that variedin weight and surface texture (slipperiness). The manipulatory action was either grasping, lifting, or posting in a slot. The task was constrained or unconstrained with respect to speed, grasp pattern, and contact force. Initiation time (pre-reach), movement time (reach), and post-contact errors were measured, to examine planning for task performance at three points in time. Results indicate that in the constrained task, the manipulatory action was planned during the initiation time, but planning for object parameters was deferred until the reach interval. With relaxed task constraints, initiation times increased,and texture and manipulatory action had independent effects on premovement planning. Errors were affected interactively by all variables. The results suggest a planning process that unfolds over time, incorporating in turn the manipulatory action, object texture, and object weight. This unfolding accommodates variables proximate to the time where they will affect physical action.

description: The upper atmospheres of the planets and their satellites are more directly exposed to sunlight and solar wind particles than the surface or the deeper atmospheric layers. At the altitudes where the associated energy is deposited, the atmospheres may become ionized and are referred to as ionospheres. The details of the photon and particle interactions with the upper atmosphere depend strongly on whether the object has anintrinsic magnetic field that may channel the precipitating particles into the atmosphere or drive the atmospheric gas out to space. Important implications of these interactions include atmospheric loss over diverse timescales, photochemistry and the formation of aerosols, which affect the evolution, composition and remote sensing of the planets (satellites). The upper atmosphere connects the planet (satellite) bulk composition to the near-planet (-satellite) environment. Understanding the relevant physics and chemistry provides insight to the past and future conditions of these objects, which is critical for understanding their evolution. This chapter introduces the basic concepts of upper atmospheres and ionospheres in our solar system, and discusses aspects of their neutral and ion composition, wind dynamics and energy budget. This knowledge is key to putting in context the observations of upper atmospheres and haze on exoplanets, and to devise a theory that explains exoplanet demographics.

description: Young transiting exoplanets (<100 Myr) provide crucial insight into atmospheric evolution via photoevaporation. However, transmission spectroscopy measurements to determine atmospheric composition and mass loss are challenging due to the activity and prominent stellar surface inhomogeneities present on young stars. We observed a full transit of V1298 Tau c, a 23 Myr, 5.59 \(R_p/R_\oplus\) planet orbiting a young solar analogue with GRACES on Gemini-North. We measured the Doppler tomographic signal of V1298 Tau c and find a projected obliquity of \(\lambda = 5^\circ \pm 15^\circ\), indicating it is well-aligned. The tomographic signal is only seen in the chromospherically driven core of the Ca II Infrared Triplet (IRT), which may be the result of star-planet interactions. Additionally, we find that excess absorption of H\(\alpha\) decreases smoothly during the transit. While this could be a tentative detection an extended hydrogen atmosphere, we find this variation can be explained by the presence of starspots with surrounding facular regions. More observations both in- and out-of the transits of V1298 Tau c are required to determine the nature of the Ca II IRT and H\(\alpha\) line variations.

A Linear Solution Method of Generalized Robust Chance Constrained Real-time Dispatch

description: In this letter, a novel solution method of generalized robust chance constrained real-time dispatch (GRCC-RTD) considering wind power uncertainty is proposed. GRCC models are advantageous in dealing with distributional uncertainty, however, they are difficult to solve because of the complex ambiguity set. By constructing traceable counterparts of the robust chance constraints and using the reformulation linearization technique, the model is equivalently transformed into a deterministic linear programming problem, which can be solved efficiently by off-the-shelf solvers. Numerical results verify the effectiveness and efficiency of the approach.

description: We study the asymptotic behaviour of the approximation, Gelfand and Kolmogorov numbers of the compact embeddings of weighted function spaces of Besov and Triebel-Lizorkin type in the case where the weights belong to a large class. We obtain the exact estimates in almost all nonlimiting situations where the quasi-Banach setting is included. At the end we present complete results on related widths for polynomial weights with small perturbations, in particular the sharp estimates in the case $α=d(\frac 1{p_2}-\frac 1{p_1})>0$ therein.

A Statistical Study on The Frequency-Dependent Damping of Slow-mode Waves in Polar Plumes and Interplumes

description: We perform a statistical study on the frequency-dependent damping of slow waves propagating along polar plumes and interplumes in the solar corona. Analysis of a large sample of extreme ultraviolet (EUV) imaging data with high spatial and temporal resolutions obtained from AIA/SDO suggests an inverse power-law dependence of the damping length on the periodicity of slow waves (i.e., the shorter period oscillations exhibit longer damping lengths), in agreement with the previous case studies. Similar behavior is observed in both plume and interplume regions studied in AIA 171 Å and AIA 193 Å passbands. It is found that the short-period (2--6 min) waves are relatively more abundant than their long period (7--30 min) counterparts in contrast to the general belief that the polar regions are dominated by the longer-period slow waves. We also derived the slope of the power spectra ($\mathrmα$, the power-law index) statistically to better understand the characteristics of turbulence present in the region. It is found that the $\mathrmα$ values and their distributions are similar in both plume and interplume structures across the two AIA passbands. At the same time, the spread of these distributions also indicates the complexity of the underlying turbulence mechanism.

description: In [She82], it is shown that four basic functional properties are enough to characterize plain Kolmogorov complexity, hence obtaining an axiomatic characterization of this notion. In this paper, we try to extend this work, both by looking at alternative axiomatic systems for plain complexity and by considering potential axiomatic systems for other types of complexity. First we show that the axiomatic system given by Shen cannot be weakened (at least in any natural way). We then give an analogue of Shen's axiomatic system for conditional complexity. In a the second part of the paper, we look at prefix-free complexity and try to construct an axiomatic system for it. We show however that the natural analogues of Shen's axiomatic systems fails to characterize prefix-free complexity.

description: We discuss the cross section formula both for massless and massive neutrinos on stable and radioactive nuclei. The latter could be of interest for the detection of cosmological neutrinos whose observation is one of the main challenges of modern cosmology. We analyze the signal to background ratio as a function of the ratio of the neutrino mass over the detector resolution and show that an energy resolution less than 0.5 eV would be required for sub-eV neutrino masses, independently of the gravitational neutrino clustering. Finally we mention the non-resonant character of neutrino capture on radioactive nuclei.

description: With TESS we have discovered about a dozen new triply eclipsing triple stars, i.e., hierarchical triple or multiple stellar systems where the outer stellar component recurrently eclipses the inner eclipsing binary or is eclipsed by it. The outer orbital periods of these systems were found to be between 1.5 months and ~1 year, and therefore, in most cases, the orbits of the EBs depart significantly from simple Keplerian motion which is manifested by strong eclipse timing variations (ETVs). For a few case studies we present the full process of studying such systems beginning with their identification through an initial characterization of the `third body' eclipses, to follow-up ground-based observations and the use of archival data, and then to the final complex photodynamical modelling. The latter includes joint (multi-epoch, multi-band) lightcurve, ETV curve, radial velocity curve (if available), and composite SED analyses. Such studies can allow for the complete characterization of the system parameters, including the detailed orbital architecture. A surprising number of overall flat systems have been found.

description: Abstract: "This technical report contains three short articles on different aspects of language and connectionism. Together, the articles illustrate both the promise and the challenges facing the application of connectionist models to central issues in language processing. Thefirst paper, (Reconstructive memory for sentences, by St. John and McClelland) describes a connectionist model in which background knowledge is used to aid recall and fill in missing arguments in sentences. The second, (Parallel distributed processing and role assignment constraints, by J. L. McClelland) discusses the application of connectionist models to the problem of using semantic/pragmatic constraints to processing sentences like 'John ate the cake that his mother baked in the oven' as opposed to 'John ate the cake that his mother baked in the dining room'. The third paper gives a brief overview of the model of past tense learning developed by Rumelhart and McClelland."
Hawking radiation and the boomerang behaviour of massive modes near a horizon

description: We discuss the behaviour of massive modes near a horizon based on a study of the dispersion relation and wave packet simulations of the Klein-Gordon equation. We point out an apparent paradox between two (in principle equivalent) pictures of black hole evaporation through Hawking radiation. In the picture in which the evaporation is due to the emission of positive-energy modes, one immediately obtains a threshold for the emission of massive particles. In the picture in which the evaporation is due to the absorption of negative-energy modes, such a threshold apparently does not exist. We resolve this paradox by tracing the evolution of the positive-energy massive modes with an energy below the threshold. These are seen to be emitted and move away from the black hole horizon, but they bounce back at a "red horizon" and are re-absorbed by the black hole, thus compensating exactly for the difference between the two pictures. For astrophysical black holes, the consequences are curious but do not affect the terrestrial constraints on observing Hawking radiation. For analogue gravity systems with massive modes, however, the consequences are crucial and rather surprising.

description: Understanding the binding mechanism in neptunyl clusters formed due to cation--cation interactions is of crucial importance in nuclear waste reprocessing and related areas of research. Since experimental manipulations with such species are often rather limited, we have to rely on quantum-chemical predictions of their electronic structures and spectroscopic parameters. In this work, we present a state-of-the-art quantum chemical study of the T-shaped and diamond-shaped neptunyl(V) and neptunyl(VI) dimers. Specifically, we scrutinize their molecular structures, (implicit and explicit) solvation effects, the interplay of static and dynamical correlation, and the influence of spin-orbit coupling on the ground state and lowest-lying excited states for different total spin states and total charges of the neptunyl dications. Furthermore, we use the picture of interacting orbitals (quantum entanglement and correlation analysis) to identify strongly correlated orbitals in the cation--cation complexes that should be included in complete active space calculations. Most importantly, our study highlights the complex interplay of correlation effects and relativistic corrections in the description of the ground and lowest-lying excited states of neptunyl dications.

We apply them by showing how information about the classical ground states of short-ranged potentials can be used to draw new conclusions about the nature of the ground states of long-ranged potentials and vice versa. They also lead to bounds on the T=0 system energies in density intervals of phase coexistence, the identification of a one-dimensional system that exhibits an infinite number of ``phase transitions," and a conjecture regarding the ground states of purely repulsive monotonic potentials.

Stereo-selective deuteration in aspartate, asparagine, lysine, and methionine amino acid residues using fumarate as a carbon source for E. coli in D2O

We propose an isotope labeling strategy for expressing proteins in E. coli using protonated natural abundance 12C carbon sources in D2O. The strategy eliminates dominant 1H-13C and 1H-1H dipolar relaxation mechanisms to produce long-lived magnetization for solution NMR spectroscopy. Isolated 1H magnetization can be transferred via through-space NOEs to slowly relaxing 1H-15N or 1H-13C methyl groups, providing the resolution needed for accurate structure determination of large protein systems by solution NMR. To fully characterize 1H/2H-isotope incorporation by NMR, we applied our labelling strategy to a model system, the WW domain from human Pin1 protein. Using glucose as sole carbon source in D2O, a very high level of protonation was observed in the aromatic side chains, as well as at the Hβ2 and Ηβ3 positions of serine and tryptophan, consistent with previous studies. With our specialized FROMP media (fumarate, rhamnose, oxalate, malonate, pyruvate), more aromatic ring positions were deuterated, and stereo-selective protonation of Hβ2 with deuteration at Ha and Hβ3 was achieved in Asp, Asn, Lys, and Met residues. In solution NMR, stereospecific chemical shift assignments for Ηβ are typically obtained in conjunction with χ1 dihedral angle determinations using 3-bond J-coupling (3JN-Hβ, 3JCO-Hβ, 3JHα-Hβ) experiments. However, due to motional averaging, the assumption of a pure rotameric state can yield incorrect χ1 dihedral angles with incorrect stereospecific assignments. In three residues, Lys28, Met30, and Asn44, the use of stereo-selective isotope labeling reversed the stereospecific chemical shift assignments and χ1 dihedral angles obtained in the traditional manner, demonstrating how stereo-selective isotope labeling can improve the accuracy of χ1 dihedral angles obtained by solution NMR.

description: Simulating the time-evolution of quantum mechanical systems is BQP-hard and expected to be one of the foremost applications of quantum computers. We consider classical algorithms for the approximation of Hamiltonian dynamics using subsampling methods from randomized numerical linear algebra. We derive a simulation technique whose runtime scales polynomially in the number of qubits and the Frobenius norm of the Hamiltonian. As an immediate application, we show that sample based quantum simulation, a type of evolution where the Hamiltonian is a density matrix, can be efficiently classically simulated under specific structural conditions. Our main technical contribution is a randomized algorithm for approximating Hermitian matrix exponentials. The proof leverages a low-rank, symmetric approximation via the Nyström method. Our results suggest that under strong sampling assumptions there exist classical poly-logarithmic time simulations of quantum computations.

description: The transition between brown dwarfs and low-mass stars is defined by the onset of hydrogen fusion in the core of an object. Current studies typically separate these objects at 80 Jupiter masses. However, this transition mass is dependent on each object’s environment and composition, with models suggesting a transition mass from 73 to 96 Jupiter masses. Here we present five companions discovered by TESS that are near this mass range transiting main sequence stars. We put them in context by exploring the properties of known transiting brown dwarfs and low-mass stars. We also discuss possible distinct characteristics for these separate populations including orbital properties as well as host star effective temperature and metallicity.

description: American stories can be told through the clothing we wear to work and for leisure, as our clothing carries nonverbal insignias of who we are. This is true especially for services workers who have to abide by strict dress codes and uniforms that let consumers know who they are. Leisure clothing thus becomes increasingly important for many service workers looking to build identity outside of the boundaries of their occupations. This auto-ethnography aims to understand that ways in which clothing is a tool of control and a means for liberation. Specifically, it investigates six items of clothing, three work uniforms and three leisurely dress items through an object-based case study, which reveals the history and impact of the items on myself (micro) and on American culture, and global cultures more generally (macro.)

description: To fully extract cosmological information from nonlinear galaxy distribution in redshift space, it is essential to include higher-order statistics beyond the two-point correlation function. In this paper, we propose a new decomposition formalism for computing the anisotropic bispectrum in redshift space and for measuring it from galaxy samples. Our formalism uses tri-polar spherical harmonic decomposition with zero total angular momentum to compress the 3D modes distribution in the redshift-space bispectrum. This approach preserves three fundamental properties of the Universe: statistical homogeneity, isotropy, and parity-symmetry, allowing us to efficiently separate the anisotropic signal induced by redshift-space distortions (RSDs) and the Alcock-Paczyński (AP) effect from the isotropic bispectrum. The relevant expansion coefficients in terms of the anisotropic signal are reduced to one multipole index $L$, and the $L> 0$ modes are induced only by the RSD or AP effects. Our formalism has two advantages: (1) we can make use of Fast Fourier Transforms (FFTs) to measure the bispectrum; (2) it gives a simple expression to correct for the survey geometry, i.e., the survey window function. As a demonstration, we measure the decomposed bispectrum from the Baryon Oscillation Spectroscopic Survey (BOSS) Data Release 12, and, for the first time, present a $14σ$ detection of the anisotropic bispectrum in the $L=2$ mode.

description: We show that a compact n-polyhedron PL embeds in a product of n trees if and only if it collapses onto an (n-1)-polyhedron. If the n-polyhedron is contractible and n\ne 3 (or n=3 and the Andrews-Curtis Conjecture holds), the product of trees may be assumed to collapse onto the image of the embedding. In contrast, there exists a 2-dimensional compact absolute retract X such that X\times I^k does not embed in any product of 2+k dendrites for each k.

description: We study theoretically some symmetry properties of spin currents and spin polarizations in multi-terminal mesoscopic spin-orbit coupled systems. Based on a scattering wave function approach, we show rigorously that in the equilibrium state no finite spin polarizations can exist in a multi-terminal mesoscopic spin-orbit coupled system (both in the leads and in the spin-orbit coupled region) and also no finite equilibrium terminal spin currents can exist. By use of a typical two-terminal mesoscopic spin-orbit coupled system as the example, we show explicitly that the nonequilibrium terminal spin currents in a multi-terminal mesoscopic spin-orbit coupled system are non-conservative in general. This non-conservation of terminal spin currents is not caused by the use of an improper definition of spin current but is intrinsic to spin-dependent transports in mesoscopic spin-orbit coupled systems. We also show that the nonequilibrium lateral edge spin accumulation induced by a longitudinal charge current in a thin strip of \textit{finite} length of a two-dimensional electronic system with intrinsic spin-orbit coupling may be non-antisymmetric in general, which implies that some cautions may need to be taken when attributing the occurrence of nonequilibrium lateral edge spin accumulation induced by a longitudinal charge current in such a system to an intrinsic spin Hall effect.

description: Metallic-line A (Am) stars are main-sequence stars of around twice the mass of the Sun that show element abundance peculiarities in their spectra. The radiative levitation and diffusive settling processes responsible for these abundance anomalies should also deplete helium from the region of the envelope that drives delta Scuti p-mode pulsations via the kappa (opacity) mechanism. Therefore, these stars are not expected to pulsate in multiple radial and nonradial modes with periods of around 2 hours, characteristic of delta Scuti stars. As part of the TESS Guest Investigator programs Cycles 2 and 3, we proposed observations in 2-minute cadence of bright (visual magnitudes 7-8) Am stars. As of March 2021, 55 target stars have been observed; among them we find four delta Scuti stars and four delta Scuti/gamma Doradus hybrid candidates, as well as many stars showing variability possibly caused by rotation and starspots. Confirming the pulsations will require further analysis and follow-up, including ruling out contamination from background or nearby stars in the field. Asteroseismic modeling of these stars will be useful to understand the reasons for their pulsations and the connections to their abundance peculiarities.

description: Everyday knowledge about living things, physical objects and the beliefs and desires of other people appears to be organized into sophisticated systems that are often called intuitive theories. Two long term goals for psychological research are to understand how these theories are mentally represented and how they are acquired. We argue that the language of thought hypothesis can help to address both questions. First, compositional languages can capture the content of intuitive theories. Second, any compositional language will generate an account of theory learning which predicts that theories with short descriptions tend to be preferred. We describe a computational framework that captures both ideas, and compare its predictions to behavioral data from a simple theory learning task.
Seeded intermodal four-wave mixing in a highly multimode fiber

description: We experimentally and theoretically investigate the process of seeded intermodal four-wave mixing in a graded index multimode fiber, pumped in the normal dispersion regime. By using a fiber with a 100 micron core diameter, we generate a parametric sideband in the C band (1530-1565 nm), hence allowing the use of an Erbium-based laser to seed the mixing process. To limit nonlinear coupling between the pump and the seed to low-order fiber modes, the waist diameter of the pump beam is properly adjusted. We observe that the superimposed seed stimulates the generation of new spectral sidebands. A detailed characterization of the spectral and spatial properties of these sidebands shows good agreement with theoretical predictions from the phase-matching conditions. Interestingly, we demonstrate that both the second and the fourth-order dispersions must be included in the phase matching conditions to get better agreement with experimental measurements. Furthermore, temporal measurements performed with a fast photodiode reveal the generation of multiple pulse structures.

description: Local properties of families of algebraic subsets $W_g$ in Birkhoff strata $Σ_{2g}$ of Gr$^{(2)}$ containing hyperelliptic curves of genus $g$ are studied. It is shown that the tangent spaces $T_g$ for $W_g$ are isomorphic to linear spaces of 2-coboundaries. Particular subsets in $W_g$ are described by the intergrable dispersionless coupled KdV systems of hydrodynamical type defining a special class of 2-cocycles and 2-coboundaries in $T_g$. It is demonstrated that the blows-ups of such 2-cocycles and 2-coboundaries and gradient catastrophes for associated integrable systems are interrelated.

The use of pronominal case in English sentence interpretation

description: This study examined adult English native speakers' processing of sentences in which pronominal case marking conflicts with word order. Previous research has shown that English speakers rely heavily on word order for assigning case roles during sentence interpretation. However, in terms of cue reliability measures, we should expect English pronominal case to be nearly as strong a cue as word order. The current study examined this issue by asking subjects to interpret grammatical and ungrammatical sentences in which case competes with word order. The results indicated that word order remains the strongest cue in English, even when the case-marking cue is available. However, for noncanonical word orders, the case-marking cue had a strong effect on sentence interpretation.

description: We present preliminary results of the identification of the variable stars brighter than 11 mag among A- and F-type stars in the northern TESS continuous viewing zone (CVZ). The aim of our efforts is to identify good candidates for the spectroscopic follow-up observations. We found out that about 63 % of all stars show some kind of variability. About one-third of the investigated stars shows a combination of variability types.

description: In this paper, we study the phase diagram of a homogeneous Bose gas with a repulsive interaction near a wide Feshbach resonance at zero temperature. The Bose-Einstein-condensation (BEC) state of atoms is a metastable state. When the scattering length $a$ exceeds a critical value depending on the atom density $n$, $na^3>0.035$, the molecular excitation energy is imaginary and the atomic BEC state is dynamically unstable against molecule formation. The BEC state of diatomic molecules has lower energy, where the atomic excitation is gapped and the molecular excitation is gapless. However when the scattering length is above another critical value, $na^3>0.0164$, the molecular BEC state becomes a unstable coherent mixture of atoms and molecules. In both BEC states, the binding energy of diatomic molecules is reduced due to the many-body effect.

description: According to the program, introducing students to the naming of numbers begins in the 1st grade. They learn how to name numbers, compare them, find the fraction of a number, and find the number itself according to the given fraction. In the 4th grade, they will have an idea of the fraction of 1 and several fractions and its written form. In geometry, the concept of naming is directly connected with the proportion of sections, the proportion of middors and the proportions of other geometric shapes.

Fractional energy density and deceleration parameters for GRDE were derived under emergent universe scenario. Also role of GRDE on the Chameleon field in the emergent universe scenario has been examined. Finally, the behaviours of the Chameleon scalar field $ϕ$, corresponding potential $V$ and associated function $f$ were investigated in presence of GRDE.
