description: We provide 28 new planet candidates that have been vetted by citizen scientists and expert astronomers. This catalog contains 9 likely rocky candidates ($R_{pl} < 2.0R_\oplus$) and 19 gaseous candidates ($R_{pl} > 2.0R_\oplus$). Within this list we find one multi-planet system (EPIC 246042088). These two sub-Neptune ($2.99 \pm 0.02R_\oplus$ and $3.44 \pm 0.02R_\oplus$) planets exist in a near 3:2 orbital resonance. The discovery of this multi-planet system is important in its addition to the list of known multi-planet systems within the K2 catalog, and more broadly in understanding the multiplicity distribution of the exoplanet population (Zink et al. 2019). The candidates on this list are anticipated to generate RV amplitudes of 0.2-18 m/s, many within the range accessible to current facilities.

description: We demonstrate for the first time the magnetic field distribution of the pure vortex state in lightly doped Mg$_{1-x}$Al$_x$B$_2$ ($x\leq 0.025$) powder samples, by using $^{11}$B NMR in magnetic fields of 23.5 and 47 kOe. The magnetic field distribution at T=5 K is Al-doping dependent, revealing a considerable decrease of anisotropy in respect to pure MgB$_2$. This result correlates nicely with magnetization measurements and is consistent with $σ$-band hole driven superconductivity for MgB$_2$.

description: Retaining premium players is key to the success of free-to-play games, but most of them do not start purchasing right after joining the game. By exploiting the exceptionally rich datasets recorded by modern video games--which provide information on the individual behavior of each and every player--survival analysis techniques can be used to predict what players are more likely to become paying (or even premium) users and when, both in terms of time and game level, the conversion will take place. Here we show that a traditional semi-parametric model (Cox regression), a random survival forest (RSF) technique and a method based on conditional inference survival ensembles all yield very promising results. However, the last approach has the advantage of being able to correct the inherent bias in RSF models by dividing the procedure into two steps: first selecting the best predictor to perform the splitting and then the best split point for that covariate. The proposed conditional inference survival ensembles method could be readily used in operational environments for early identification of premium players and the parts of the game that may prompt them to become paying users. Such knowledge would allow developers to induce their conversion and, more generally, to better understand the needs of their players and provide them with a personalized experience, thereby increasing their engagement and paving the way to higher monetization.

description: Defining the observable ${\bf ϕ}$ canonically conjugate to the number observable ${\bf N}$ has long been an open problem in quantum theory. The problem stems from the fact that ${\bf N}$ is bounded from below. In a previous work we have shown how to define the absolute phase observable ${\bf Φ}\equiv |{\bfϕ}|$ by suitably restricting the Hilbert space of $x$ and $p$ like variables. Here we show that also from the classical point of view, there is no rigorous definition for the phase even though it's absolute value is well defined.

description: Dukelsky, Martín-Delgado, Nishino and Sierra (Europhys. Lett., 43, 457 (1998) - hereafter referred to as DMNS) investigated the matrix product method (MPM), comparing it with the infinite-size density matrix renormalization group (DMRG). For equivalent basis size, the MPM produces an improved variational energy over that produced by DMRG and, unlike DMRG, produces a translationally-invariant wavefunction. The DMRG results presented were significantly worse than the MPM, caused by a shallow bound state appearing at the join of the two DMRG blocks. They also suggested that the DMRG results can be improved by using an alternate superblock construction $[B] \bullet [B]$ for the last few steps of the calculation. In this comment, we show that the DMRG results presented by DMNS are in error and the artificial bound state produced by the standard superblock configuration is very small even for $m=2$ states kept. In addition, we calculate explicitly the energy and wavefunction for the $[B] \bullet [B]$ superblock structure and verify that the energy coincides with that of the MPM, as conjectured by S. Ostlund and S. Rommer (Phys. Rev. Lett., 75, 3537 (1995)).

description: Pyruvate : ferredoxin oxidoreductase (PFO) and iron only hydrogenase ([Fe]-HYD) are common enzymes among eukaryotic microbes that inhabit anaerobic niches. Their function is to maintain redox balance by donating electrons from food oxidation via ferredoxin (Fd) to protons, generating H2 as a waste product. Operating in series, they constitute a soluble electron transport chain of one-electron transfers between FeS clusters. They fulfil the same function—redox balance—served by two electron-transfers in the NADH- and O2-dependent respiratory chains of mitochondria. Although they possess O2-sensitive FeS clusters, PFO, Fd and [Fe]-HYD are also present among numerous algae that produce O2. The evolutionary persistence of these enzymes among eukaryotic aerobes is traditionally explained as adaptation to facultative anaerobic growth. Here, we show that algae express enzymes of anaerobic energy metabolism at ambient O2 levels (21% v/v), Chlamydomonas reinhardtii expresses them with diurnal regulation. High O2 environments arose on Earth only some approximately 450 million years ago. Gene presence/absence and gene expression data indicate that during the transition to high O2 environments and terrestrialization, diverse algal lineages retained enzymes of Fd-dependent one-electron-based redox balance, while the land plant and land animal lineages underwent irreversible specialization to redox balance involving the O2-insensitive two-electron carrier NADH.

description: We studied the crystal and magnetic structure of the La$_{1-x}$Ca$_{x}$MnO$_{3}$ compound for $x=0.8$ and $x=0.85$. At T=300 K both samples are paramagnetic with crystallographic symmetry $Pnma$. At low temperatures they undergo a monoclinic distortion from orthorhombic $Pnma$-type structure with $a_p\sqrt{2}\times 2a_p\times a_p\sqrt{2}$ to a monoclinic structure with ($a_p\sqrt{2}\times 2a_p\times a_p\sqrt{2}$, $β=90+ε\sim 91.4^{\rm o}$) and $P2_1/m$ space group below $T_N$. The onset of the structural transformation coincides with the development of the $C$-type long range antiferromagnetic order with propagation vector ${\bf k}=({1/2},0,{1/2})$. The monoclinic unit cell allowed us to determine the direction of the Mn magnetic moment with respect to the crystallographic axes: it is perpendicular to the propagation vector, ${\bf m}\perp {\bf k}=({1/2},0,{1/2})$. The amplitude of the ordered magnetic moment at $T=1.6$ K is found to be $2.53(2)$ and $2.47(2)μ_{B}$ for $x=0.8$ and 0.85, respectively.

description: Computerized registration between maxillofacial cone-beam computed tomography (CT) images and a scanned dental model is an essential prerequisite in surgical planning for dental implants or orthognathic surgery. We propose a novel method that performs fully automatic registration between a cone-beam CT image and an optically scanned model. To build a robust and automatic initial registration method, our method applies deep-pose regression neural networks in a reduced domain (i.e., 2-dimensional image). Subsequently, fine registration is performed via optimal clusters. Majority voting system achieves globally optimal transformations while each cluster attempts to optimize local transformation parameters. The coherency of clusters determines their candidacy for the optimal cluster set. The outlying regions in the iso-surface are effectively removed based on the consensus among the optimal clusters. The accuracy of registration was evaluated by the Euclidean distance of 10 landmarks on a scanned model which were annotated by the experts in the field. The experiments show that the proposed method's registration accuracy, measured in landmark distance, outperforms other existing methods by 30.77% to 70%. In addition to achieving high accuracy, our proposed method requires neither human-interactions nor priors (e.g., iso-surface extraction). The main significance of our study is twofold: 1) the employment of light-weighted neural networks which indicates the applicability of neural network in extracting pose cues that can be easily obtained and 2) the introduction of an optimal cluster-based registration method that can avoid metal artifacts during the matching procedures.

description: Water insecurity concerns drove San Antonio, Texas to pursue a controversial $3.4 billion groundwater transfer project from central Texas aquifers. The 228 km Vista Ridge Pipeline (VRP) would increase water supplies by 20%. Analysis through Q-Method revealed three social perspectives surrounding the VRP. Project Advocates offer particular views of urban water security, risk, and accountability. The creation of new hydro-social territories helps to explain Landowner Opposition, while Governance Failure offers a foundational criticism of the underlying assumptions and the institutional innovation of private-public partnership that advanced the VRP. Overall, our paper demonstrates that the VRP is differentiated according to views of risk, water law, and groundwater science. Policy deliberations on future urban water security should include these perspectives as a means to improve water governance, especially as policies and infrastructure for urban water security creates new hydro-social territories.

First, given a set E of homotopically nontrivial, pairwise disjoint, pairwise nonisotopic simple closed curves on S, we determine precisely when a multitwist on E is an element of T by defining an equivalence relation on E and then applying graph theory. Second, we prove that an arbitrary Abelian subgroup of T has rank < 2g-4.

description: In this article we examine a class of wormhole and flux tube like solutions to 5D vacuum Einstein equations. These solutions possess generic local anisotropy, and their local isotropic limit is shown to be conformally equivalent to the spherically symmetric 5D solutions of gr-qc/9807086. The anisotropic solutions investigated here have two physically distinct signatures: First, they can give rise to angular-dependent, anisotropic ``electromagnetic'' interactions. Second, they can result in a gravitational running of the ``electric'' and ``magnetic'' charges of the solutions. This gravitational running of the electromagnetic charges is linear rather than logarithmic, and could thus serve as an indirect signal for the presence of higher dimensions. The local anisotropy of these solutions is modeled using the technique of anholonomic frames with respect to which the metrics are diagonalized. If holonomic coordinates frames were used then such metrics would have off-diagonal components.

description: The high pressure lattice dynamics of rhombohedral antimony have been studied by a combination of diffuse scattering and inelastic x-ray scattering. The evolution of the phonon behavior as function of pressure was analyzed by means of two theoretical approaches: density functional perturbation theory and symmetry-based phenomenological phase transition analysis. This paper focuses on the first structural phase transition, SbI-SbIV, and the role of vibrations in leading the transition. The phonon dispersion exhibits complex behaviour as one approaches the structural transition, with the branches, corresponding to the two transitions happening at high pressure in the Va elements (A7-to-BCC and A7-to-PC) both showing softening.

description: In this essay it will be shown that Decoherence Model and Einstein Equivalence Principle are conceptually incompatible. In other words, assuming only the validity of the Weak Equivalence Principle the present work concludes that we face two possibilities: (i) if Decoherence Model provides a correct description of nature at quantum level, then there are systems which violate Local Position Invariance, or, (ii) if all the postulates behind Einstein Equivalence Principle are valid, even on quantum realm, then Decoherence Model breaks down in curved spacetimes. Finally, the present results are confronted against Schiff's conjecture.

description: Natural substances are extensively used as biostimulants in agriculture. Notably, horn-manure preparation (HMP) is fermented cow manure sprayed at low concentrations onto biodynamically cultivated fields. The present study investigated the effect of HMP on the growth of garden cress (Lepidium sativum L.) cultivated in a bioassay (randomized block design, n = 20). Seedlings were cultivated in a water medium. Treatments of a drop of HMP suspension (1 µl or 0.1 µl) or of water (Control) were added to the medium. Long-term series of trials, with two different HMPs, were conducted over 18 and 9 months with 76 and 38 trials, respectively. In the first series, the effect of a 1 µl drop of HMP suspension on root growth was significant overall (−2.4%, p = 0.004, Tukey-Kramer-test) and in 35.5% of the individual trials (p

description: Empfehlungssysteme, die mit Hilfe latenter Faktormodelle Empfehlungen generieren, arbeiten äußerst genau und sind entsprechend weit verbreitet. Da die Berechnung der Empfehlungen jedoch auf der statistischen Auswertung von Benutzerbewertungen basiert, gestaltet es sich schwierig, die Empfehlungen dem Nutzer gegenüber zu erklären. Daher werden die Systeme häufig als intransparent wahrgenommen und können oft ihr volles Potential nicht entfalten. Erste Ansätze zeigen allerdings, dass die latenten Faktoren solcher Modelle semantische Eigenschaften der Produkte widerspiegeln. Dabei ist bislang unklar, ob die zum Teil sehr komplexe Parametrisierung, die z.B. die Anzahl der Faktoren festlegt, Auswirkungen auf die semantische Verständlichkeit hat. Da dies sehr von der subjektiven Wahrnehmung abhängt, präsentieren wir mit LittleMissFits ein Online-Spiel, das es erlaubt, mittels Crowd-Sourcing die Konsistenz der latenten Faktoren zu untersuchen. Die Ergebnisse einer Nutzerstudie mit diesem Spiel zeigen, dass eine höhere Anzahl von Faktoren das Modell weniger verständlich erscheinen lässt. Darüber hinaus fanden sich Unterschiede innerhalb der Faktormodelle bezüglich der Verständlichkeit der einzelnen Faktoren. Zusammengenommen stellen die Ergebnisse eine wertvolle Grundlage dar, um künftig die Transparenz entsprechender Empfehlungssysteme zu steigern.

description: Let $k$ be a finitely generated field of characteristic $p>0$ and $X$ a smooth and proper scheme over $k$. Recent works of Cadoret, Hui and Tamagawa show that, if $X$ satisfies the $\ell$-adic Tate conjecture for divisors for every prime $\ell\neq p$, the Galois invariant subgroup $Br(X_{\overline k})[p']^{π_1(k)}$ of the prime-to-$p$ torsion of the geometric Brauer group of $X$ is finite. The main result of this note is that, for every integer $d\geq 1$, there exists a constant $C:=C(X,d)$ such that for every finite field extension $k \subseteq k'$ with $[k':k]\leq d$ and every $(\overline k/k')$-form $Y$ of $X$ one has $|(Br(Y\times_{k'}\overline k)[p']^{π_1(k')}|\leq C$. The theorem is a consequence of general results on forms of compatible systems of $π_1(k)$-representations and it extends to positive characteristic a recent result of Orr and Skorobogatov in characteristic zero.

description: When a pianist is playing on a MIDI keyboard, the computer does not know with which hand a key was pressed. With the help of a Recurrent Neural Network (RNN), we assign played MIDI notes to one of the two hands. We compare our new approach with an existing heuristic algorithm and show that RNNs perform better. The solution is real-time capable and can be used via OSC from any programming environment. A non real-time capable variant provides slightly higher accuracy. Our solution can be used in music notation software to assign the left or right hand to the upper or lower staff automatically. Another application is live playing, where different synthesizer sounds can be mapped to the left and right hand.

description: We apply the formalism of the continuous time random walk to the study of financial data. The entire distribution of prices can be obtained once two auxiliary densities are known. These are the probability densities for the pausing time between successive jumps and the corresponding probability density for the magnitude of a jump. We have applied the formalism to data on the US dollar/Deutsche Mark future exchange, finding good agreement between theory and the observed data.

description: There has long been a discrepancy between microwave conductivity measurements in high temperature superconductors and the conductivity spectrum expected in the simplest models for impurity scattering in a d-wave superconductor. Here we present a new type of broadband measurement of microwave surface resistance that finally shows some of the spectral features expected for a d_{x^2-y^2} pairing state. Cusp-shaped conductivity spectra, consistent with weak impurity scattering of nodal quasiparticles, were obtained in the 0.6-21 GHz frequency range in highly ordered crystals of YBa_2Cu_3O_{6.50} and YBa_2Cu_3O_{6.99}.

description: The present scale for measuring study satisfaction is based on The Satisfaction With Life Scale by Diener et al. (1985) and was adapted to the domain of studying in higher education. In two studies, the unidimensional German five-item scale showed good internal consistencies and good model fit. Strict measurement invariance was established for gender, study program, type of higher education institution, and across time. Evidence for the validity of the interpretation of test scores was gathered with satisfactory results. Overall, the scale can be recommended as a valid, reliable, and time-efficient instrument. Furthermore, we validated a three-item and a single-item measure to assess study satisfaction in surveys with severe time constraints. Both short measures have acceptable psychometric properties.

Effective two-level models for highly efficient inner-state enantio-separation based on cyclic three-level systems of chiral molecules

description: Based on cyclic three-level systems of chiral molecules, we propose two methods to realize highly efficient inner-state enantio-separations of a chiral mixture with the two enantiomers initially prepared in their ground states. Our methods work in the region where the evolutions of the two enantiomers can be described by their corresponding effective two-level models, simultaneously. The approximately $100\%$-efficiency inner-state enantio-separations can be realized when the probability occupying the ground state of one enantiomer becomes $0$ by experiencing half-integer periods of its corresponding on-resonance Rabi oscillation and in the meanwhile the other one still stays approximately in the ground state, under the conditions that the two enantiomers are governed by the effective on-resonance and large-detuning two-level models, respectively. Alternatively, the exactly $100\%$-efficiency inner-state enantio-separation can be obtained when the probabilities occupying the ground states of the two enantiomers simultaneously experience half-integer and integer periods of their corresponding on-resonance and detuned (instead of largely-detuned) Rabi oscillations with final $0$ and $1$ probabilities occupying the ground state, respectively.

description: We investigate the generalized second law for two-dimensional black holes in equilibrium (Hartle-Hawking) and nonequilibrium (Unruh) with the heat bath surrounding the black holes. We obtain a simple expression for the change of total entropy in terms of covariant thermodynamic variables, which is valid not only for the Hartle-Hawking state but also for the Unruh state up to leading order, without assuming a quasi-stationary evolution of the black holes. Using this expression, it is shown that the rate of local entropy production is non-negative in the two-dimensional black hole systems.

description: The Airborne Instruments nUFO – NonTrivial UFO – is a new Digital Musical Instrument (DMI) that is designed to allow the musician completely free movement of the interactor object in space (airborne). Non-triviality (after H. v. Foerster) is mainly implemented through synthesis processes with a rich “inner life”, i.e. apparently intrinsic behavior, more akin to synthetic creatures than conventional instruments. The innovative Influx parameter mapping allows for a rich interaction with these processes with little or no training, making it suitable both for beginners that are enabled to create highly immersive sound worlds, and for experienced musicians in search for radically new physical approaches to digital synthesis.

(Figs 49, 52, 56, 60)
 Type locality. South Africa, Eastern Cape Province, Mkhambati NR, 31°16ƍS, 29°59.8ƍE.
 Type material. HOLOTYPE: 3: ‘ South Africa, Eastern Cape, Mkhambati NR, indig.forest at Mkhambati river, 28.i.2012, 31°16S; 29°59.8E, J. Janák lgt. // forest litter, sifting // Octavius sarkae xhosa ssp. n., J. Janák det. 2013’ (TMSA). PARATYPES: 4337 ♀♀: same data as holotype (JJRC).
 Description. In most external characters very similar to O. sarkae sp. nov., but slightly smaller, body length 1.5–1.8 mm (M 1.6 mm, HT 1.7 mm), forebody length 0.7–0.8 mm (M 0.8 mm, HT 0.8 mm); eyes on average slightly larger (length temples – eyes R 1.26–1.48, M 1.39, HT 1.47).
Other measurements: width head – pronotum R 0.88–0.91, M 0.89, HT 0.88; pronotum width – length R 1.10–1.17, M 1.14, HT 1.13; elytra width – length R 1.38–1.54, M 1.48, HT 1.47.
 Male. Sternite 8 and 9 as in O. sarkae sp. nov. Aedeagus similar as in O. sarkae sp. nov. (n = 5, length 0.43–0.45 mm, M 0.44 mm, HT 0.44 mm), but apical portion of internal sclerotised plate hook-shaped and median lobe with low sharp ventral ridge apically (Fig. 49, 52).
 Differential diagnosis. Octavius sarkae xhosa subsp. nov. differs from the nominotypical subspecies of O. sarkae sp. nov. and O. sarkae ntsubane subsp. nov. only by the aedeagus, which is characterised by the apical portion of internal sclerotised plate hook-shaped, not rounded or ¿shtail-shaped, and by the median lobe with low ventral ridge apically. Octavius sarkae xhosa subsp. nov. can be distingushed externally (sometimes with dif¿culties) from O. sarkae ntsubane subsp. n. by distinct granulation between anterior margin and transverse impression (in the latter subspecies this region is coarsely reticulate and wrinkled).
 Bionomics. All specimens have been found in siftings of forest litter in indigenous forest.
 Distribution. Octavius sarkae xhosa sp. nov. has been currently recorded only from Mkhambati NR in Eastern Cape Province, South Africa (Figs 56, 60).
 Etymology. This species is named after the tribe Xhosa, who inhabit the area where the type locality is situated.

description: Virtual Reality (VR) allows us to perceive the world through any possible embodiment – the avatar. Behavioral changes due to the strong bond between the user and the virtual avatar is known as Proteus Effect. Previous work found that the Proteus Effect occurs when characteristics of the appearance are associated with knowledge and experiences gained by anticipated entities or stereotypes. Based on the findings that the Proteus Effect can trigger behavioral changes, we hypothesize that the appearance of an avatar in VR can be manipulated in a way that users will perform tasks better than they would perform them using their real or any casual embodiment. As one of the most important human behavioral characteristics is exerting force, we are planning to conduct a study investigating if muscular or wispy avatars are able to change physical forces of the physical self. Our hypothesis is that people will apply more force when they interact in a more powerful-looking appearance. An effect would have far-reaching consequences and implications for the interactions with avatars in HCI and VR.
