description: The pseudogap phenomena have been a long-standing mystery of the cuprate high-temperature superconductors. The pseudogap in the electron-doped cuprates has been attributed to band folding due to antiferromagnetic (AFM) long-range order or short-range correlation. We performed an angle-resolved photoemission spectroscopy (ARPES) study of the electron-doped cuprates Pr$_{1.3-x}$La$_{0.7}$Ce$_x$CuO$_4$ showing spin-glass, disordered AFM behaviors, and superconductivity at low temperatures and, by measurements with fine momentum cuts, found that the gap opens on the unfolded Fermi surface rather than the AFM Brillouin zone boundary. The gap did not show a node, following the full symmetry of the Brillouin zone, and its magnitude decreased from the zone-diagonal to ($π$,0) directions, opposite to the hole-doped case. These observations were reproduced by cluster dynamical-mean-field-theory (CDMFT) calculation, which took into account electron correlation precisely within a (CuO$_2$)$_4$ cluster. The present experimental and theoretical results are consistent with the mechanism that electron or hole doping into a Mott insulator creates an in-gap band that are separated from the upper or lower Hubbard band by the pseudogap.
Application of integral equations to neutrino mass searches in beta decay

description: A new mathematical method for elucidating neutrino mass from beta decay is studied. It is based upon the solutions of transformed Fredholm and Volterra integral equations. In principle, theoretical beta-particle spectra can consist of several neutrino-mass eigenvalues. Integration of the theoretical beta spectrum with a normalized instrumental response function results in the Fredholm integral equation of the first kind. This equation is transformed in such a way that the solution of it is a superposition of the Heaviside step-functions, one for each neutrino mass eigenvalue. A series expansion leading to matrix linear equations is then derived to solve the transformed Fredholm equation. Another approach is derived when the theoretical beta spectrum is obtained by a separate deconvolution of the observed spectrum. It is then proven that the transformed Fredholm equation reduces to the Abel integral equation. The Abel equation has a general integral solution, which is proven in this work by using a specific function for the beta spectrum. As an example, a numerical solution of the Abel integral equation is also provided, which has a fractional sensitivity of about 0.001 for subtle neutrino eigenvalue searches, and can distinguish from experimental beta-spectrum discrepancies, such as shape and energy nonlinearities.

Triatoma guazu

description: Species. T. guazu Lent, Jurberg and Galvão
Etymology. Its provenance is stated as its country of origin (Paraguay). Since it is one of the largest representatives of the Triatoma genus, it was given the species name guazu, meaning “large” in the Guarani language (Lent, Jurberg & Galvão 1996: 313).
Original citation. “Da proveniência constava o país de origem (Paraguai). Por ser um dos maiores representantes do gênero Triatoma recebeu o nome específico guazu, que na língua guarani significa grande” (Lent, Jurberg & Galvão 1996: 313).

description: We investigate wide-angle pi^0 photoproduction within the handbag approach to twist-3 accuracy. In contrast to earlier work both the 2-particle as well as the 3-particle twist-3 contributions are taken into account. It is shown that both are needed for consistent results that respect gauge invariance and crossing properties. The numerical studies reveal the dominance of the twist-3 contribution. With it fair agreement with the recent CLAS measurement of the pi^0 cross section is obtained. We briefly comment also on wide-angle photoproduction of other pseudoscalar mesons.

description: We explicitly describe the solution of the G$_2$-Laplacian flow starting from an extremally Ricci-pinched closed G$_2$-structure on a compact 7-manifold and we investigate its properties. In particular, we show that the solution exists for all real times and that it remains extremally Ricci-pinched. This result holds more generally on any 7-manifold whenever the intrinsic torsion of the extremally Ricci-pinched G$_2$-structure has constant norm. We also discuss various examples.

Ghostly Halos in Dwarf Galaxies: Constraints on the Star Formation Efficiency before Reionization

Year: 2018
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: Stellar halos observed around normal galaxies are extended and faint stellar structures formed by debris of tidally disrupted dwarf galaxies accreted over time by the host galaxy. Around dwarf galaxies, these stellar halos may not exist if all the accreted satellites are dark halos without stars. However, if a stellar halo is found in sufficiently small mass dwarfs, the whole stellar halo is composed of tidal debris of fossil galaxies, and we refer to it as ghostly halo. Fossil galaxies are called so because they formed most of their stars before the epoch of reionization, and have been identified as the ultra-faint dwarf galaxies found around the Milky Way and M31.
 In this paper we carry out semi-analytical simulations to characterize the sizes and stellar masses of ghostly stellar halos in dwarf galaxies as a function of their dark matter halo mass. By comparing the models to observations of six isolated dwarf galaxies in the Local Group showing evidence of extended stellar halos, we are able to constrain the star formation efficiency in fossil galaxies. We find that at redshift z~6, dark matter halos in the mass range 10^7-10^9 M_sun have a mean star formation efficiency f_* = M_*/M_{dm} ~ 0.05%-0.1% nearly constant as a function of the dark matter halo mass. There is a tentative indication of a sharp increase of f_* at M_{dm} ~ 10^6-10^7 M_sun, but it is very uncertain and based on only one dwarf galaxy (Leo~T).

Remarks. The Galicia Bank specimens correspond to published descriptions and figures of Copidozoum exiguum (e.g. Zabala et al. 1993; Hayward & Ryland 1998; Reverter-Gil & Fernández-Pulpeiro 1999a), which was first described from off Santander (N Spain) by Barroso (1920) as Callopora exigua. The species is apparently widespread, occurring in the upper bathyal between 180 and 2018 m depth along the continental shelf of the NE Atlantic and western Mediterranean. Its geographic distribution ranges from the Tunisian shelf (Harmelin 1979) to the Western Approaches to the English Channel, and it is commonly found on the coral Lophelia (Hayward & Ryland 1978, 1998; Harmelin & d’Hondt 1992; Zabala et al. 1993). Reverter-Gil & Fernández-Pulpeiro (1999a) already reported this species from different localities on the continental slope close to Galicia Bank between 450 and 688 m depth.
We here illustrate the ancestrula of C. exiguum for the first time (Fig 7). It is similar to an autozooid but smaller and with 14 marginal spines. The ancestrula is surrounded by five autozooids, one distal, two distolateral and two proximolateral.
SD, standard deviation; N, number of measurements
The ooecium of the hyperstomial ovicell is formed by the distal kenozooid, which is invisible from frontal view. The ectooecium is smooth and almost entirely calcified except for a crescentic membranous area on its proximal edge. The borders of this area are thickened.
Copidozoum exiguum is an abundant species, found at nine localities on Galicia Bank, ranging from 826 to 1138 m depth. The majority of the colonies encrust corals while one was found on a shell and another one on a rock.

description: Scapherpeton tectum, sp. nov.
Represented by a vertebra which is one of the best preserved in the collection. The most prominent speciﬁc character is seen in the entire rooﬁng over of the neural canal between the anterior zygapophyses, and in the downward production of the inferior median line of the centrum, and accompanying downward prolongation of the articular cups. The chordal perforation is at the superior fourth of the vertical diameter of the cups. The neural spine is produced backwards and curved tipwards, and is narrowed between the posterior zygapophyses, and is striate grooved on the under surface. About half of the posterior zygapophysis projects beyond the edge of the cup of the centrum. Immediately below the anterior edge of the posterior zygapophysis, the diapophysis begins. It is vertical, of an irregular ﬁgure S in section, and is directed outwards and backwards. A foramen passes under its middle, emerging a little before the middle of the same horizontal diameter of the centrum. It is joined by another which strikes it from below at right angles. There is a deep notch embraced between the superior part of the diapophysis and the posterior zygapophysis. The neural canal is wider than deep.
A fragment accompanied this vertebra when found, which resembles the articular portion of the mandible. There is no angle projecting behind the quadrate facet, which is oblique, truncating the extremity of the ramus. The lower edge is acute, behind roughened, and a thickening extends along the middle of the inner side of the ramns so far as preserved. The character is that of a Urodele Batrachian.

Continued fractions and irrationality exponents for modified Engel and Pierce series

Publisher: name: arXiv
Year: 2018
Subjects: subject: Number Theory (math.NT)

description: An Engel series is a sum of reciprocals of a non-decreasing sequence $(x_n)$ of positive integers, which is such that each term is divisible by the previous one, and a Pierce series is an alternating sum of the reciprocals of a sequence with the same property. Given an arbitrary rational number, we show that there is a family of Engel series which when added to it produces a transcendental number $α$ whose continued fraction expansion is determined explicitly by the corresponding sequence $(x_n)$, where the latter is generated by a certain nonlinear recurrence of second order. We also present an analogous result for a rational number with a Pierce series added to or subtracted from it. In both situations (a rational number combined with either an Engel or a Pierce series), the irrationality exponent is bounded below by $(3+\sqrt{5})/2$, and we further identify infinite families of transcendental numbers $α$ whose irrationality exponent can be computed precisely. In addition, we construct the continued fraction expansion for an arbitrary rational number added to an Engel series with the stronger property that $x_j^2$ divides $x_{j+1}$ for all $j$.
Hard exclusive processes involving kaons

description: Hard exclusive electroproduction of kaons as well as the kaon-induced exclusive Drell-Yan process are investigated within the handbag approach which is based on factorization in hard subprocesses and soft generalized parton distributions (GPDs). The kaon-hyperon transition GPDs occurring here, are related to the proton GPDs by flavor symmetry. The latter ones are taken from analyses of pion electroproduction. Like in hard processes involving pions the transversity GPDs play an important role in the processes of interest - the transverse cross sections are larger than (or, for the Drell-Yan process, about equal to) the longitudinal ones. The evolution of the transversity GPDs is taken into account for the first time but, as the analysis reveals, it is a minor effect in the range of photon virtualities of interest. The predictions for the cross sections agree fairly well with the sparse available electroproduction data.

On Solving Reachability in Grid Digraphs using a Psuedoseparator

description: The reachability problem asks to decide if there exists a path from one vertex to another in a digraph. In a grid digraph, the vertices are the points of a two-dimensional square grid, and an edge can occur between a vertex and its immediate horizontal and vertical neighbors only.
 Asano and Doerr (CCCG'11) presented the first simultaneous time-space bound for reachability in grid digraphs by solving the problem in polynomial time and $O(n^{1/2 + ε})$ space. In 2018, the space complexity was improved to $\tilde{O}(n^{1/3})$ by Ashida and Nakagawa (SoCG'18).
 In this paper, we show that there exists a polynomial-time algorithm that uses $O(n^{1/4 + ε})$ space to solve the reachability problem in a grid digraph containing $n$ vertices. We define and construct a new separator-like device called pseudoseparator to develop a divide-and-conquer algorithm. This algorithm works in a space-efficient manner to solve reachability.
