description: In-app advertisements have become a major revenue source for app developers in the mobile app ecosystem. Ad libraries play an integral part in this ecosystem as app developers integrate these libraries into their apps to display ads. In this paper, we study ad library integration practices by analyzing 35,459 updates of 1,837 top free-to-download apps of the Google Play Store. We observe that ad libraries (e.g., Google AdMob) are not always used for serving ads -- 22.5% of the apps that integrate Google AdMob do not display ads. They instead depend on Google AdMob for analytical purposes. Among the apps that display ads, we observe that 57.9% of them integrate multiple ad libraries. We observe that such integration of multiple ad libraries occurs commonly in apps with a large number of downloads and ones in app categories with a high proportion of ad-displaying apps. We manually analyze a sample of apps and derive a set of rules to automatically identify four common strategies for integrating multiple ad libraries. Our analysis of the apps across the identified strategies shows that app developers prefer to manage their own integrations instead of using off-the-shelf features of ad libraries for integrating multiple ad libraries. Our findings are valuable for ad library developers who wish to learn first hand about the challenges of integrating ad libraries.

description: This chapter details the various data processing steps used to retrieve useful data  from the lidar waveform (other than depth of an individual pulse). The introductory section describes the sequence of coordinate transformations and translations required to produce a georeferenced lidar point cloud. The next section presents a general approach to the inverse problem of lidar waveform processing with the goal of retrieving inherent optical properties (IOPs) of seawater, followed by a sections discussing retrieval of the water diffuse attenuation coefficient and the estimate of bottom reflectance at the lidar wavelength. The final section is a discussion of the effects of forward scattering on the shape and position of the surface reflection and bottom pulse.

description: Schizophoria (S.) sp.
Fig. 3A.
Material.—The figured partial ventral valve NYSM 15701.
Remarks.—A single partial ventral valve representing Schizophoria (S.) sp. was recovered from Hanover Shale shell bed. The exfoliated ventral valve does not permit a definite species assignment, although it features molds of the impressed bilobate diductor scars (Fig. 4A) divided by a medial ridge (site of adductor attachment) extending 2–3 mm beyond the diductor muscle field. The only Late Devonian species of Schizophoria described from New York with the ventral medial adductor ridge extending well beyond the diductor scars is S. (S.) impressa (Hall 1867: pl. 8: 11–19).

description: Determination of nuclear moments for many nuclei relies on the computation of hyperfine constants, with theoretical uncertainties directly affecting the resulting uncertainties of the nuclear moments. In this work we improve the precision of such method by including for the first time an iterative solution of equations for the core triple cluster amplitudes into the relativistic coupled-cluster method, with large-scale complete basis sets. We carried out calculations of the energies and magnetic dipole and electric quadrupole hyperfine structure constants for the low-lying states of 229Th^(3+) in the framework of such relativistic coupled-cluster single double triple (CCSDT) method. We present a detailed study of various corrections to all calculated properties. Using the theory results and experimental data we found the nuclear magnetic dipole and electric quadrupole moments to be mu = 0.366(6)*mu_N and Q = 3.11(2) eb, and reducing the uncertainty of the quadrupole moment by a factor of three. The Bohr-Weisskopf effect of the finite nuclear magnetization is investigated, with bounds placed on the deviation of the magnetization distribution from the uniform one.

description: Philoteris (the modern name is Watfa) was founded under Ptolemy II in the 3rd century BC, and abandoned in the 4th century AD. A geomagnetic plan of the site in the north-western Fayum Oasis, produced by T. Herbich and his team in 2011–2014, shows water ways and canals around and within the village to allow for a thorough understanding of the water supply of the inhabitants of the village, and the gardens and fields around. An impressive building outside the settlement and well connected to the water canals attracted attention; it turned out to be the only archaeologically attested Gymnasium in Egypt so far. The 2016 campaign focussed on that building and its connection to the water network around.

Remarks.— Thirteen specimens recovered (four complete adult shells) are consistent with Hall’s species described originally from the “arenaceous beds of the Chemung group near Leon, Conewego, and Randolph in Cattaraugus county”. Consequently the precise origin of his type material remains unknown. See comments on distribution of this form above. Schuchert and Cooper (1932) questionably attributed to William’s Orthis leonensis to Thiemella. Dutro (1981: fig. 7) was the first to definitively attribute this form to Thiemella.

description: Privacy and security-related concerns are growing as machine learning reaches diverse application domains. The data holders want to train with private data while exploiting accelerators, such as GPUs, that are hosted in the cloud. However, Cloud systems are vulnerable to attackers that compromise the privacy of data and integrity of computations. This work presents DarKnight, a framework for large DNN training while protecting input privacy and computation integrity. DarKnight relies on cooperative execution between trusted execution environments (TEE) and accelerators, where the TEE provides privacy and integrity verification, while accelerators perform the computation heavy linear algebraic operations.

description: We develop a maximum relative entropy formalism to generate optimal approximations to probability distributions. The central results consist in (a) justifying the use of relative entropy as the uniquely natural criterion to select a preferred approximation from within a family of trial parameterized distributions, and (b) to obtain the optimal approximation by marginalizing over parameters using the method of maximum entropy and information geometry. As an illustration we apply our method to simple fluids. The "exact" canonical distribution is approximated by that of a fluid of hard spheres. The proposed method first determines the preferred value of the hard-sphere diameter, and then obtains an optimal hard-sphere approximation by a suitably weighed average over different hard-sphere diameters. This leads to a considerable improvement in accounting for the soft-core nature of the interatomic potential. As a numerical demonstration, the radial distribution function and the equation of state for a Lennard-Jones fluid (argon) are compared with results from molecular dynamics simulations.

Low-scale minimal linear seesaw model for neutrino mass and flavor mixing

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

description: We consider an extension of the Standard Model with three right-handed (RH) neutrinos and a Dirac pair of extra sterile neutrinos, odd under a discrete $Z_2$ symmetry, in order to have left-right symmetry in the neutrino content and obtain tiny neutrino masses from the latter ones only. Our working hypothesis is that the heavy RH neutrinos do not influence phenomenology at low energies. We use the usual high-scale seesaw to suppress all of the mass terms involving RH neutrinos and a low-scale minimal variant of the linear seesaw led by the Dirac mass of the extra sterile neutrinos to provide the small mass of active neutrinos. One of the active neutrinos is massless, which fixes the mass of the other two on the basis of a soft breaking of the $Z_2$ symmetry. The mixing between the extra neutrinos makes for a particle that effectively behaves like a Dirac sterile neutrino with mass around the GeV level.

Fig. 3E, F.
Material.—Two mature shells NYSM 15699, NYSM 15722, and a juvenile ventral valve NYSM 15694, 15 unnumbered partial compacted ventral and dorsal valves on parts and counterparts of split slabs.
Remarks.—The limited material (three partial ventral valves and numerous fragments) do not permit a definitive generic assignment. The angular plications originating near the beak of the ventral valve are a common feature seen in a number of genera known from upper Frasnian–lower Famennian deposits. It is likely that this form represents a species of Ripidiorhynchus Sartenaer (1966). The best−preserved ventral valves are close to the Frasnian form R. kermanensis Brice (1999) illustrated by her from the Frasnian of Kerman Province of eastern Iran. The Hanover material is provisionally placed in that genus pending discovery of additional well−preserved shells in the Upper Devonian of New York.
The specimens (Fig. 3E, F) also bear an external resemblance to shells of Sinotectirostrum Sartenaer (1961a). Of the species described from North America, the limited material (NYSM 15723 with shoulder angle of 115°) from the Hanover Shale is most similar to S. medicinale deceptum Sartenaer (1969: his paratype GSC 15900) described from very low in the Sassenach Formation of western Alberta. Raasch (1989) lists species of Sinotectirostrum from six of his seven Famennian brachiopod zones (zones DFM1 to DFM6) that span the interval from the Lower Pa. triangularis through the Pa. trachytera zones of the Upper Devonian Famennian conodont zonation. Sartenaer (1969: fig. 2) portrays the range inception of S. medicinale deceptum very low in the Lower Pa. triangularis Zone, below species typical of his Eoparaphorynchus ZoneinwesternCanada.IftheHanoverspecimensprovetobe Sinotectirostrum, then the occurrence of this genus in New York (very low in the Lower Pa. triangularis Zone) would be similar to its lowest occurrences in the lowermost Famennian in western Canada. Ripidiorhynchus? sp. bears some resemblance to Rhynchonella (Stenocisma) contracta (Hall 1867: 351, pl. 55: 26–39) attributed by Linsley (1994) to Cupularostrum Sartenaer (1961b).

During its excavation in the late 19th and early 20th centuries, more than 140 funerary stelae were found in the debris of the monastic church. Even though all inscriptions of the stelae were published by H. Munier in 1930/31, there is hardly any information about the stelae themselves. Furthermore, current research on the Coptic written evidence of Deir Anba Hadra encourages a reinvestigation of the stelae. Therefore, a comprehensive documentation of the stelae kept in the Coptic Museum in Cairo was begun in 2017.

Its foundation is connected to local traditions about Hatre, a hermit saint and bishop of Aswan in the later 4th century AD whose hermitage seems to have been localized here. The project investigates the usage history of Deir Anba Hadra from its beginnings in the 7th–8th century up to the latest evidence of Christian-Coptic, Christian-Arabic and Muslim visitors’ inscriptions in the Mamluk period. In the course of work a new documentation of the architecture and building history of the church and the workshops as well as a comprehensive documentation of the epigraphic evidence and the wall paintings have been made.
Nontrivial critical crossover between directed percolation models: Effect of infinitely many absorbing states

Year: 2007
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: At non-equilibrium phase transitions into absorbing (trapped) states, it is well known that the directed percolation (DP) critical scaling is shared by two classes of models with a single (S) absorbing state and with infinitely many (IM) absorbing states. We study the crossover behavior in one dimension, arising from a considerable reduction of the number of absorbing states (typically from the IM-type to the S-type DP models), by following two different (excitatory or inhibitory) routes which make the auxiliary field density abruptly jump at the crossover. Along the excitatory route, the system becomes overly activated even for an infinitesimal perturbation and its crossover becomes discontinuous. Along the inhibitory route, we find continuous crossover with the universal crossover exponent $ϕ\simeq 1.78(6)$, which is argued to be equal to $ν_\|$, the relaxation time exponent of the DP universality class on a general footing. This conjecture is also confirmed in the case of the directed Ising (parity-conserving) class. Finally, we discuss the effect of diffusion to the IM-type models and suggest an argument why diffusive models with some hybrid-type reactions should belong to the DP class.

Remarks.—This form is a relatively common element of the HanoverShalefauna,althoughmostfrequentlyrepresentedby broken shell fragments of dorsal and ventral valves. The angular plications bounding the sulcus and upper part of the tongue (Fig. 3G) arise anterior of mid−valve, and do not extend posteriorly to near the beak. External ornament preserved on external molds of partial ventral valves shows very fine concentric growth lines and very fine radial microcapillate microornament. It resembles species of Chapinella Savage et al., 1978, and is provisionally placed in that genus pending recovery of sufficient specimens to verify its identity.

description: In this paper, we explore an electromechanical metastructure consisting of a periodic array of piezoelectric bimorphs with resistive-inductive loads for simultaneous harvesting and attenuation of traveling wave energy. We develop fully coupled analytical models, i.e., an electroelastic transfer matrix method, and exploit both locally-resonant and Bragg band gaps to achieve a multifunctional metastructure which is capable for maximum energy conversion and vibration mitigation in a broadband fashion. Our analytical and numerical results show that the proposed metastructure can achieve energy harvesting efficiency up to 95% at the local resonance frequency of 3.18 kHz, while reaching about 51% at 5.8 kHz near the upper limit of the Bragg band gap. The broadband vibration mitigation performance based on 50% power attenuation is predicted as 1.8 kHz and 1.1 kHz in the vicinity of the band gaps. The theoretical frameworks and the applicability of the proposed metastructure are validated using a full-scale experimental setup.

Work in 2016 continued on embedding these settlements in their ancient natural environment. The focus last season was on some very prominent natural features – long narrow raised ridges, running roughly North-South. The assumption that each of these features represented the remains of two alluvial levees, flanking a former Nile branch, could be verified by auger core drillings.

description: In geophysics, wave propagation in elastic media is a crucial subject. In this context, seismology has made significant progress as a result of numerous advances, among these stands out the advancement of numerical methods such as the finite-difference one. Usually, seismic wave propagation in elastic media results in complex systems of partial differential equations, whose solutions cannot be obtained in an analytical way, especially when dealing with heterogeneous media. In consequence, there exists a necessity to implement numerical methods. However, the available information about the construction of a numerical solution of these equations is not as explicit as it should be. Our main goal is to provide pedagogical instructions for undergraduate students who want to improve their computational skills as well as their knowledge of the subject. The last through current teaching methods involving challenging problems and transversal tools. Particularly, we provide a brief description of the equations and a detailed description of the numerical solution of the seismic wave equation. Furthermore, we model two different seismic explosive sources in both homogeneous and heterogeneous media as an illustrative example. In the results, we include velocity maps showing wave propagation in the x-z plane, and the z-velocity as a function of time measured in a series of detectors distributed in the numerical domain.

description: Focusing on the investigation of late predynastic settlement remains, during the recent work a second installation consisting of small parallel walls was excavated, underlying the structure excavated in 2015. Such installations, hitherto unknown in predynastic Egypt, are well-known in the Near East since Neolithic times and were used for the drying of agricultural products, such as grain or fruits. The newly discovered structure dates to the Naqada IIIA2 period. During this time first mud brick walls seem to occur at Buto, at least in the investigated area. Previously, until Naqada IIIA1, housing consisted of light constructions, probably built in wattle and daub technique. According to the associated pottery, these light structures are related to the Lower Egyptian Buto-Maadi culture. While a comprehensive picture cannot be drawn yet, several features shed light on the agricultural and household activities of the inhabitants, such as different kind of ovens used for cooking, or a battery of ovens built of fire bars which belonged presumably to a Naqada IID brewery.

description: An eikonal expansion is used to provide systematic corrections to the eikonal approximation through order $1/k^2$, where $k$ is the wave number. Electron wave functions are obtained for the Dirac equation with a Coulomb potential. They are used to investigate distorted-wave matrix elements for quasi-elastic electron scattering from a nucleus. A form of effective-momentum approximation is obtained using trajectory-dependent eikonal phases and focusing factors. Fixing the Coulomb distortion effects at the center of the nucleus, the often-used ema approximation is recovered. Comparisons of these approximations are made with full calculations using the electron eikonal wave functions. The ema results are found to agree well with the full calculations.

description: Probing the fundamental magnetic interactions in layered magnetic structures is essential to the understanding of the properties of these systems. Such physical quantities can be experimentally measured by probing the magnon dispersion relation over the whole Brillouin zone. On this regard, high wavevector magnons in ultrathin Fe and Co multilayers grown on W(110) and Ir(111) are studied using spin polarized high resolution electron energy loss spectroscopy. In layers of Fe and Co films deposited on W(110) the magnons are probed along the [001] direction in the wavevector range of 0.25 inverse angstrom to 1.3 inverse angstrom. Experimental results reveal two magnon modes which exhibit a clear dispersion as expected. The results are described within the Heisenberg model. In the case of 1ML Co/1ML Fe/W(110) structure, the interface Fe intralayer exchange coupling constants are found to be enhanced when compared to 1ML Fe/W(110). The interlayer exchange coupling was found to be weak (4.5 meV) relative to the 2ML Fe deposited on the same substrate (7.6 meV). The antisymmteric Dzyaloshinskii-Moriya interaction (DMI) was observed to be enhanced when compared to the 2ML Fe/W(110) system. Fe films with the thickness of 2ML and 3ML showed very soft magnons when they were grown on Ir(111). This indicates rather small exchange coupling constants in these systems. For the case of 2ML Co/1ML Fe/Ir(111) two magnon modes were observed. Comparing the experimental results with those of ab initio calculations it is observed that the exchange interaction in the Fe layer at the interface is very weak, with a large antiferromagnetic contribution. The results provide a deeper understanding of the magnetic interactions in layered structures and may help to advance the understanding of the role of symmetric and antisymmetric exchange interaction in low dimensional magnetism.

description: In recent years, $γ$-ray emission has been detected from star-forming galaxies (SFGs) in the local universe, including M82, NGC 253, Arp 220 and M33. The bulk of this emission is thought to be of hadronic origin, arising from the interactions of cosmic rays (CRs) with the interstellar medium of their host galaxy. Distant SFGs are presumably also bright in $γ$-rays. Although they would not be resolvable as point sources, distant unresolved SFG populations contribute $γ$-rays to the extra-galactic $γ$-ray background (EGB). Despite the wealth of high-quality all-sky EGB data collected over more than a decade of operation with the \textit{Fermi}-LAT $γ$-ray space telescope, the exact contribution of SFGs to the EGB remains unsettled. In this study, we model the $γ$-ray emission from SFG populations and demonstrate that such emission can be characterized by just a small number of physically-motivated parameters. We further show that source populations would leave anisotropic signatures in the EGB, which could be used to yield information about the underlying properties, dynamics and evolution of CR-rich SFGs.

description: The aim of the first two years stage of the project that is planned to last for four years is to investigate and to document Nubian vernacular architecture and material culture preserved in the two abandoned villages on the island Bigge in Upper Egypt. The fabric of the two settlements originates from the early 20th century and represents one of very few examples which remained after the inundation of the Egyptian part of Nubia by the waters of Lake Nasser in the 1960s. The combined architectural and ethnological approach should enable a thorough understanding of the material frame of life of the island’s rural community.

Cyrtospirifer hornellensis; Greiner 1957: 28–29, pl. 7: 1–5, 6 (not dorsal valve specimen on right−hand part of image of Yale Peabody Museum number 19435B), and 7.
Material.—Figured specimens NYSM 15691 and NYSM 15692.
Remarks.—The available specimens are consistent with the species as described by Greiner (1957: 29). It must be pointed out that Greiner (1957) illustrated at least two distinct genera under the name C. hornellensis. One of the two dorsal valves (his “larger, presumably gerontic, individual” of Yale Peabody Museum number 19435B) illustrated in his pl. 7 (fig. 6, right−hand specimen) represents a new genus, which will be described (Ma and Day personal communication 2001) from the lower Famennian of South China.
Cyrtospirifer hornellensis is about half the size (width), has a narrower sinus and fewer flank plications, and lacks the medial groove on the dorsal fold of the much larger Cyrtospirifer sulcifer (Hall and Clarke, 1894). That form serves as the nominal species for the lowest Famennian C. sulcifer Assemblage Zone of Dutro (1981: 80, figs. 2, 7). As defined, that zone spans the interval of the Canadaway Group, immediately above the Java Formation of New York. Cyrtospirifer sulcifer (Hall and Clarke, 1894) is not a true Cyrtospirifer and is considered here a species of Pripyatispirifer Pushkin (1996). According to Greiner (1957) his illustrated specimens of C. hornellensis were collected 140 feet (42.6 meters) below the top of the upper Frasnian Wiscoy Formation (now Java Formation) and overlying deposits of the lower Famennian “Casaseraga formation” (= Caneadea Formation of the modern nomenclature). Greiner portrays its upper range (see his fig. 4) as somewhere high in the lower Famennian. Thus far, our material represents its lowest Famennian occurrence directly associated with Lower Pa. triangularis Zone conodonts in the upper part of the Hanover Shale of eastern North America.

An existential-phenomenological approach to understanding the meaning of grief

Publisher: name: University of British Columbia

description: The study investigated the experience of grief with the aim of understanding the meaning of the phenomenon. Meaning is assumed to be a beginning or a platform from which theory, research and practice can evolve. Eight individuals, four women and four men, ranging in age from 33 to 50 were recruited from a network of friends and acquaintances, for participation in the study. Each person was asked to describe a personal grief experience and to validate the analysis within the context of three interviews. The interviews were taped, transcribed and used as the data for the study. The meaning of grief was studied by using an existential-phenomenological approach. The analysis followed the descriptive methodologies outlined by Giorgi (1975) in Duquesne Studies in Phenomenological Psychology II and by Colaizzi (1978) in Existential-Phenomenological Alternatives for Psychology. The results directly address the question: What- is the meaning of grief? The major constituents (or themes) were described and woven into an exhaustive phenomenological description of grief. The essential structure, derived from the phenomenological description, is the condensed descriptive definition of grief and was presented in an unequivocal statement of meaning.

description: Within the framework of exact quantum electrodynamics in dispersing and absorbing media, we have studied the quantum state of the radiation emitted from an initially in the upper state prepared two-level atom in a high-$Q$ cavity, including the regime where the emitted photon belongs to a wave packet that simultaneously covers the areas inside and outside the cavity. For both continuing atom--field interaction and short-term atom--field interaction, we have determined the spatio-temporal shape of the excited outgoing wave packet and calculated the efficiency of the wave packet to carry a one-photon Fock state. Furthermore, we have made contact with quantum noise theories where the intracavity field and the field outside the cavity are regarded as approximately representing independent degrees of freedom such that two separate Hilbert spaces can be introduced.

description: Finite projective (lattice) geometries defined over rings instead of fields have recently been recognized to be of great importance for quantum information theory. We believe that there is much more potential hidden in these geometries to be unleashed for physics. There exist specific rings over which the projective spaces feature two principally distinct kinds of basic constituents (points and/or higher-rank linear subspaces), intricately interwoven with each other -- unimodular and non-unimodular. We conjecture that these two projective "degrees of freedom" can rudimentary be associated with spatial and temporal dimensions of physics, respectively. Our hypothesis is illustrated on the projective line over the smallest ring of ternions. Both the fundamental difference and intricate connection between time and space are demonstrated, and even the ring geometrical germs of the observed macroscopic dimensionality (3+1) of space-time and the arrow of time are outlined. Some other conceptual implications of this speculative model (like a hierarchical structure of physical systems) are also mentioned.

description: The cult of the god Osiris in Abydos led to countless ritual and votive material in Umm el-Qaab, the former ancient necropolis of the early dynastic kings of Egypt. The focus of the campaign and further work carried out in 2016 and 2017 focused on conservatory measures on several in situ deposits. These included several wooden boxes and a fragile cult figure of the god. One focus of the investigations of small-scale finds was the documentation of seal imprints from the time of the Middle Kingdom up to the 30th dynasty.

description: Pre-theoretically the term construction is widely used to refer to a language-specific phrasal or clausal pattern (e.g., the ‘passive’ construction, the ‘copula’ construction, the ‘participial’ construction, etc.). But in recent years the term construction has come to be used theoretically in Construction Grammar (e.g., Croft 2001) as a way to refer to conventionalized “pairings of [linguistic] form with semantic or discourse function, including morphemes or words, idioms, partially lexically filled and fully general phrasal patterns” (Goldberg 2006: 5).

description: We describe a new high-contrast imaging capability well suited for studying planet-forming disks: near-infrared (NIR) high-contrast spectropolarimetric imaging with the Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) system coupled with the Coronagraphic High Angular Resolution Imaging Spectrograph (CHARIS) integral field spectrograph (IFS). The advent of extreme adaptive optics (AO) systems, like SCExAO, has enabled recovery of planet-mass companions at the expected locations of gas-giant formation in young disks alongside disk structures (such as gaps or spirals) that may indicate protoplanet formation. In combination with SCExAO, the CHARIS IFS in polarimetry mode allows characterization of these systems at wavelengths spanning the NIR J, H, and K bands ($1.1-2.4$ $μm$, $R\sim20$) and at angular separations as small as 0.04". By comparing the resulting images with forward-modeled scattered light or 3D radiative-transfer models, the likely origins of any observed features can be assessed. Utilization of swift optimization algorithms, such as differential evolution (DE), to identify model parameters that best reproduce the observations allows plausible disk geometries to be explored efficiently. The recent addition of CHARIS's unique integral field spectropolarimetry mode has further facilitated the study of planet-forming disks -- aiding in the confirmation of candidate protoplanets, the diagnosis of disk structures, and the characterization of dust grain populations. We summarize preliminary results for two young planet-forming disk systems based on observations with the novel integral field spectropolarimetry mode for SCExAO/CHARIS.

description: E-Laboratories are important components of e- learning environments, especially in scientific and technical disciplines. First widespread E-Labs consisted in proposing simulations of real systems (virtual labs), as building remote labs (remote control of real systems) was difficult by lack of industrial standards and common protocols. Nowadays, robotics and automation technologies make easier the interfacing of systems with computers. In this frame, many researchers (such as those mentioned in [1]) focus on how to set up such a remote control. But, only a few of them deal with the educational point of view of the problem. This paper outlines our current research and reflection about remote laboratory modelling.
