description: LncRNA plays an important role in many biological and disease progression by binding to related proteins. However, the experimental methods for studying lncRNA-protein interactions are time-consuming and expensive. Although there are a few models designed to predict the interactions of ncRNA-protein, they all have some common drawbacks that limit their predictive performance. In this study, we present a model called HLPI-Ensemble designed specifically for human lncRNA-protein interactions. HLPI-Ensemble adopts the ensemble strategy based on three mainstream machine learning algorithms of Support Vector Machines (SVM), Random Forests (RF) and Extreme Gradient Boosting (XGB) to generate HLPI-SVM Ensemble, HLPI-RF Ensemble and HLPI-XGB Ensemble, respectively. The results of 10-fold cross-validation show that HLPI-SVM Ensemble, HLPI-RF Ensemble and HLPI-XGB Ensemble achieved AUCs of 0.95, 0.96 and 0.96, respectively, in the test dataset. Furthermore, we compared the performance of the HLPI-Ensemble models with the previous models through external validation dataset. The results show that the false positives (FPs) of HLPI-Ensemble models are much lower than that of the previous models, and other evaluation indicators of HLPI-Ensemble models are also higher than those of the previous models. It is further showed that HLPI-Ensemble models are superior in predicting human lncRNA-protein interaction compared with previous models.

description: We report on the source Gaia 17bpi and identify it as a new, ongoing FU Ori type outburst, associated with a young stellar object. The optical lightcurve from Gaia exhibited a 3.5 mag rise with the source appearing to plateau in mid/late 2018. Mid-infrared observations from NEOWISE also show a $>$3 mag rise that occurred in two stages, with the second one coincident with the optical brightening, and the first one preceding the optical brightening by $\sim$1.5 years. We model the outburst as having started between October and December of 2014. This wavelength-dependent aspect of young star accretion-driven outbursts has never been documented before. Both the mid-infrared and the optical colors of the object become bluer as the outburst proceeds. Optical spectroscopic characteristics in the outburst phase include: a GK-type absorption spectrum, strong wind/outflow in e.g. Mgb, NaD, H$α$, KI, OI, and CaII profiles, and detection of LiI 6707 Å. The infrared spectrum in the outburst phase is similar to that of an M-type spectrum, notably exhibiting prominent $H_2O$ and $^{12}$CO (2-0) bandhead absorption in the K-band, and likely HeI wind in the Y-band. The new FU Ori source Gaia 17bpi is associated with a little-studied dark cloud in the galactic plane, located at a distance of 1.27 kpc.

description: We propose a potential for wormlike polymer chains which can be used to model the low-temperature conformational structures. We successfully reproduced helix ground states up to 6.5 helical loops, using the multicanonical Monte Carlo simulation method. We demonstrate that the coil-helix transition involves four distinct phases: coil(gaslike), collapsed globular(liquidlike), and two helical phases I and II (both solidlike). The helix I phase is characterized by a helical structure with dangling loose ends, and the helix II phase corresponds to a near perfect helix ordering in the entire crystallized chain.

description: Обнаружены статистически значимые регулярные субструктуры в двумерном распределении галактик в богатых скоплениях с красными смещениями до 0,15. Исходные данные были взяты из «Каталога скоплений и групп галактик» (Panko & Flin, 2006). Основным типом подструктур являются линейные вытянутые области перекрытия в кластерном поле. Направление линейной подструктуры обычно указывает на ближайшего соседа. Кроме того, мы нашли регулярные подструктуры типа X или Y, а также короткие и / или компактные цепи. Яркие галактики в скоплениях расположены в основном в регулярных субструктурах, и галактики в цепочках также демонстрируют значительное выравнивание вдоль цепочки. Обнаруженные особенности можно рассматривать как результат образования скопления галактик на пересечении нитей ТМ или взаимодействия нити со стенкой.

description: We study limit theorems in the context of random perturbations of dispersing billiards in finite and infinite measure. In the context of a planar periodic Lorentz gas with finite horizon, we consider random perturbations in the form of movements and deformations of scatterers. We prove a Central Limit Theorem for the cell index of planar motion, as well as a mixing Local Limit Theorem for the cell index with piecewise Hölder continuous observables. In the context of the infinite measure random system, we prove limit theorems regarding visits to new obstacles and self-intersections, as well as decorrelation estimates. The main tool we use is the adaptation of anisotropic Banach spaces to the random setting.

 Remarks. This species has a large hump on the upper part of the thorax, and relatively large AL arches. The cephalis is somewhat rectangular in shape, with flattened sides and a point at the apex. Pores on the thorax can be slightly irregular in size and shape. This species differs from Lophophaena nadezdae (Pl. 23, Figs. 1A – 2C) in that it lacks spines on the thorax, other than the lateral and dorsal spines, and has a relatively broader cephalis.

Beyond the Hubbard-I Solution with a One-Pole Self-Energy at Half-Filling with the Moment Approach: Non-Linear Effects

description: We have postulated a single pole for the self-energy, $Σ(\vec{k},ω)$, looking for the consequences on the one-particle Green function, $G(\vec{k},ω)$ in the Hubbard model. We find that $G(\vec{k},ω)$ satisfies the first two sum rules or moments of Nolting (Z. Physik 255, 25 (1972)) for any values of the two unknown $\vec{k}$ parameters of $Σ(\vec{k},ω)$. In order to find these two parameters we have used the third and four sum rules of Nolting. $G(\vec{k},ω)$ turns out to be identical to the one of Nolting (Z. Physik 225, 25 (1972)), which is beyond a Hubbard-I solution since satisfies four sum rules. With our proposal we have been able to obtain an expansion in powers of $U$ for the self-energy (here to second order in $U$). We present numerical results at half-filling for 1- the static spin susceptibility, $χ(T)$ vs $T/t$ and 2- the band narrowing parameter, $B(T)$ vs $T/t$. The two-pole Ansatz of Nolting for the one-particle Green function is equivalent to a single pole Ansatz for the self-energy which remains the fundamental quantity for more elaborated calculations when, for example, lifetime effects are included.

Bipedal Walking with Corrective Actions in the Tilt Phase Space
Creators: name: Allgeuer, Philipp
name: Behnke, Sven
Publisher: name: arXiv
Year: 2018
Subjects: subject: Robotics (cs.RO)
subject: FOS: Computer and information sciences

description: Many methods exist for a bipedal robot to keep its balance while walking. In addition to step size and timing, other strategies are possible that influence the stability of the robot without interfering with the target direction and speed of locomotion. This paper introduces a multifaceted feedback controller that uses numerous different feedback mechanisms, collectively termed corrective actions, to stabilise a core keypoint-based gait. The feedback controller is experimentally effective, yet free of any physical model of the robot, very computationally inexpensive, and requires only a single 6-axis IMU sensor. Due to these low requirements, the approach is deemed to be highly portable between robots, and was specifically also designed to target lower cost robots that have suboptimal sensing, actuation and computational resources. The IMU data is used to estimate the yaw-independent tilt orientation of the robot, expressed in the so-called tilt phase space, and is the source of all feedback provided by the controller. Experimental validation is performed in simulation as well as on real robot hardware.

Plate 21, Figs. 6A–C.
 Remarks. Only a single specimen of this unusual species was observed in our material, but it was so distinct that we chose to illustrate it here for completeness. The shape of the cephalis and bulge at the neck area closely resemble the structure of Lophophaena amictoria (Pl. 21, Figs. 1A – 3B), but this species has an undulating thorax with much stronger feet and is more than twice its size. The curved, billowing nature of the thorax is similar to Lophophaena undulatum (Pl. 21, Figs. 4–5), but this species differs in its significantly larger size, larger and better developed cephalis, and more elongated neck area with prominent bulge on the dorsal side. L. undulatum also lacks the feet of Lophophaena sp. M and L. amictoria, although some specimens do develop long ribs from the dorsal and lateral spines that run partway down the thorax. This species appears to be distinct yet have some relationship to the previously-mentioned lophophaenid taxa; more material must be examined before it can be formally described.
 Material examined. 1 specimen from sample 321-1337D-23H- 6, 134–137cm (Late Miocene).
 Range. Late Miocene in the EEP (Table 1).

description: In this research, the properties of bismuth potassium titanate modified by bismuth nickel titanate ceramics were investigated. XRD showed that all ceramics exhibited a single perovskite structure. The crystal structure changed from a tetragonal to a cubic phase with increasing modifier content. Average grain size decreased while the bulk density and hardness increased with the modifier. The improvement of mechanical properties was related to the change in microstructural and density. The 5 – 10 mol% ceramics showed the good electrical properties. The maximum dielectric properties (ε′ = 1763, tan δ = 0.0697) were obtained for the 10 mol% ceramic. The highest piezoelectric voltage constant (g33 = 23.92 × 10−3 Vm/N) and the off-resonance figure of merit (FoM) for energy harvesting (~ 6.64 pm2/N) were obtained for the 5 mol% ceramic, which was ~ 5.0 times (or 399%) as compared to the pure BKT ceramic. The additive also produced an improvement in the magnetization-magnetic field hysteresis loop. The obtained results suggested that the additive not only enhanced the mechanical properties but also improved the ferroelectric, magnetic, and energy harvesting performances of the studied ceramics.

description: As is known, any realization of SU(2) in the phase space of a dynamical system can be generalized to accommodate the exceptional supergroup $D(2,1;α)$, which is the most general $\mathcal{N}{=}\,4$ supersymmetric extension of the conformal group in one spatial dimension. We construct novel spinning extensions of $D(2,1;α)$ superconformal mechanics by adjusting the SU(2) generators associated with the relativistic spinning particle coupled to a spherically symmetric Einstein-Maxwell background. The angular sector of the full superconformal system corresponds to the orbital motion of a particle coupled to a symmetric Euler top, which represents the spin degrees of freedom. This particle moves either on the two-sphere, optionally in the external field of a Dirac monopole, or in the SU(2) group manifold. Each case is proven to be superintegrable, and explicit solutions are given.

Radiative alpha-capture cross sections from realistic nucleon-nucleon interactions and variational Monte Carlo wave functions

description: We report the first calculations of cross sections for the radiative capture reactions t(alpha,gamma)^7Li and ^3He(alpha,gamma)^7Be below 2 MeV which use wave functions derived from realistic nucleon-nucleon interactions by the variational Monte Carlo technique. After examining several small corrections to the dominant E1 operator, we find energy dependences for the low-energy S-factors which agree reasonably with experimental measurements. There is no contradiction with the previous theoretical understanding of these processes, but the zero-energy derivative of the t(alpha,gamma)^7Li S-factor is smaller than in most models. While this method can in principle predict cross section normalizations, the normalizations of our results are mostly too low.

description: We propose a variational method for identifying lattice operators in a critical quantum spin chain with scaling operators in the underlying conformal field theory (CFT). In particular, this allows us to build a lattice version of the primary operators of the CFT, from which we can numerically estimate the operator product expansion coefficients $C_{αβγ}^{\textrm{ CFT}}$. We demonstrate the approach with the critical Ising quantum spin chain.

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We analyze models of extended Gauge Mediation in the context of the NMSSM, concentrating on supersymmetric spectra with light gluinos, low fine-tuning and decays of the lightest neutralino leading to displaced vertices. While the minimal scenario has rather heavy gluinos as a result of restrictions from the Higgs sector, we propose two new models in which the gluino can be as light as allowed by direct searches at the LHC, with a mass of about 1.7 TeV and 2.0 TeV, respectively. Both models have a tuning of a few permille, and lead to an interesting phenomenology due to a light singlet sector. A singlet state at around 98 GeV can account for the LEP excess, while the singlino has a mass of the order of 100 GeV and decays to b-jets and the gravitino, with decay lengths of a few cm.

 Remarks. This species has a crown of bladed spines in the upper third of the cephalis, which is very elongated. It differs from L. witjazii (Pl. 25, Figs. 5A–B) in that its cephalis is more elongated and does not flare outward at the top, instead forming a cylinder shape. As only four specimens were observed, the range of morphology is not well understood.
 Material examined. 4 specimens observed from samples 321-1337A-12H-5, 23–26cm (Late Miocene), 321- 1337A-3H- 2, 103–106cm (Middle Pleistocene), 321-1337A-2H-3, 76–79cm (Late Pleistocene), and 321-1337D-1H-1, 0–3cm (Recent).

description: Using state-of-the-art dynamical simulations of globular clusters, including radiation reaction during black hole encounters and a cosmological model of star cluster formation, we create a realistic population of dynamically-formed binary black hole mergers across cosmic space and time. We show that in the local universe, 10% of these binaries form as the result of gravitational-wave emission between unbound black holes during chaotic resonant encounters, with roughly half of those events having eccentricities detectable by current ground-based gravitational-wave detectors. The mergers that occur inside clusters typically have lower masses than binaries that were ejected from the cluster many Gyrs ago. Gravitational-wave captures from globular clusters contribute 1-2 Gpc^-3 yr^-1 to the binary merger rate in the local universe, increasing to ~10 Gpc^-3 yr^-1 at z~3. Finally, we discuss some of the technical difficulties associated with post-Newtonian scattering encounters, and how care must be taken when measuring the binary parameters during a dynamical capture.

Nuclear Stopping as A Probe to In-medium Nucleon-nucleon Cross Section in Intermediate Energy Heavy Ion Collisions

description: Using an isospin-dependent quantum molecular dynamics, nuclear stopping in intermediate heavy ion collisions has been studied. The calculation has been done for colliding systems with different neutron-proton ratios in beam energy ranging from 15MeV/u to 150MeV/u. It is found that, in the energy region from above Fermi energy to 150MeV/u, nuclear stopping is very sensitive to the isospin dependence of in-medium nucleon-nucleon cross section, but insensitive to symmetry potential. From this investigation, we propose that nuclear stopping can be used as a new probe to extract the information on the isospin dependence of in-medium nucleon-nucleon cross section in intermediate energy heavy ion collisions.
Combinatorics of nondeterministic walks of the Dyck and Motzkin type

description: This paper introduces nondeterministic walks, a new variant of one-dimensional discrete walks. At each step, a nondeterministic walk draws a random set of steps from a predefined set of sets and explores all possible extensions in parallel. We introduce our new model on Dyck steps with the nondeterministic step set {{--1}, {1}, {--1, 1}} and Motzkin steps with the nondeterministic step set {{--1}, {0}, {1}, {--1, 0}, {--1, 1}, {0, 1}, {--1, 0, 1}}. For general lists of step sets and a given length, we express the generating function of nondeterministic walks where at least one of the walks explored in parallel is a bridge (ends at the origin). In the particular cases of Dyck and Motzkin steps, we also compute the asymptotic probability that at least one of those parallel walks is a meander (stays nonnegative) or an excursion (stays nonnegative and ends at the origin). This research is motivated by the study of networks involving encapsulations and decapsulations of protocols. Our results are obtained using generating functions and analytic combinatorics.

description: We present a quantitative continuum theory of ``flocking'': the collective coherent motion of large numbers of self-propelled organisms. Our model predicts the existence of an ``ordered phase'' of flocks, in which all members of the flock move together with the same mean velocity. This coherent motion of the flock is an example of spontaneously broken symmetry. The ``Goldstone modes'' associated with this ``spontaneously broken rotational symmetry'' are fluctuations in the direction of motion of a large part of the flock away from the mean direction. These ``Goldstone modes'' mix with modes associated with conservation of bird number to produce propagating sound modes. These sound modes lead to enormous fluctuations of the density of the flock. Our model is similar in many ways to the Navier-Stokes equations for a simple compressible fluid; in other ways, it resembles a relaxational time dependent Ginsburg-Landau theory for an $n = d$ component isotropic ferromagnet. In spatial dimensions $d > 4$, the long distance behavior is correctly described by a linearized theory. For $d < 4$, non-linear fluctuation effects radically alter the long distance behavior, making it different from that of any known equilibrium model. In particular, we find that in $d = 2$, where we can calculate the scaling exponents \underline{exactly}, flocks exhibit a true, long-range ordered, spontaneously broken symmetry state, in contrast to equilibrium systems, which cannot spontaneously break a continuous symmetry in $d = 2$ (the ``Mermin-Wagner'' theorem). We make detailed predictions for various correlation functions that could be measured either in simulations, or by quantitative imaging of real flocks.
