description: Dieser Beitrag präsentiert erstmals alle 65 bis heute bekannten Grabdenkmäler des 1. und frühen 2. Jhs. aus Simitthus/Chimtou (Tunesien) und seinem Umland. Diese neben zeitgleichen Gruppen aus Karthago, Ammaedara und Mactaris bedeutendste Grabmarkerserie der frühkaiserzeitlichen Africa Proconsularis ist ein wichtiges Indiz für die tiefgreifende Transformation der frührömischen Stadt. Die kombinierte ikonographisch-epigraphische Analyse der Grabdenkmäler aus drei neu eingerichteten Nekropolen bietet neue Einblicke in die während des 1. Jhs stark expandierende colonia. Die lokalen Steinmetzwerkstätten bedienten sich eines regional in vorrömischer Zeit etablierten Rahmendekors und Typenspektrums. ›Afrikanische‹ Namen und eine lateinisch-neopunische Bilingue zeugen von der Beibehaltung bestehender Grabmarkierungstraditionen. Anhand der Gentilnamen, einiger Statuenmotive und Funerärsymbole sind gleichzeitig klare Bezüge nach Mittelitalien offenkundig. Aus dieser Region scheinen zahlreiche Neusiedler, darunter negotiatores-Familien, an den wichtigen Straßenknotenpunkt Simitthus mit seinen Marmorbrüchen übergesiedelt zu sein. Unter den 16 erstmals vorgelegten Grabsteinen finden sich neue Militärs und Beamte. Grabdenkmäler mit analoger Stilistik aus dem Umland belegen die Dominanz der simitthuensischen Steinmetzschulen im mittleren Majradatal.
description: This contribution presents for the first time all 65 known funerary monuments of the 1st and early 2nd cent. A.D. from Simitthus/Chimtou (Tunisia) and the surrounding area. Along with contemporaneous groups from Carthage, Ammaedara and Mactaris, this grave marker series from early imperial Africa Proconsularis provides important evidence for the fundamental transformation of the early Roman city. Combined iconographic and epigraphic analysis of the funerary monuments from three newly established necropoleis offers new insights into the colonia, which greatly expanded during the 1st cent. A.D. The local stonemason workshops employed a decorative and typological spectrum established in the region in pre-Roman times. ›African‹ names and a Latin-Neo-Punic bilingual inscription attest to the maintenance of existing grave marking traditions. At the same time, gentile names, certain statue motifs and funerary symbols show strong links with central Italy. Many new settlers, among them families of negotiatores, seem to have moved from that region to the important hub of Simitthus with its marble quarries. New military personnel and officials are among the 16 grave stones presented for the first time. Funerary monuments in analogous style from the surrounding area demonstrate the dominance of Simitthus' stonemason workshops in the middle Majrada valley.

description: Abstract

Mutual transformational shifts in workplace synergy combined with parallel insatiable needs for operational sustainability through people and data bottleneck management make the remote work paradigm interweaving multiverse reality vs dream-rooted response demand triggers. Hitting some of the high notes will require the use of other built-in couches, and that's where Salesforce comes into the picture; the importance of apps like Chatter, adding a Slack levels integration, and using more advanced analytics with tools like Einstein have become the keys to success for remote running teams. This article explores how Salesforce supports remote work through task automation, improving communication, and providing real-time visibility through the case study of a specific technology company. In the case study, productivity increased by 35% and employee engagement increased significantly. The paper also outlines challenges like data security, user adoption, and potential solutions. Finally, a billion-dollar view as we explore how exciting technologies that make AI possible can unleash productivity and management possibilities for remote work to the next level. This analysis shines a light upon Salesforce's usefulness in the remote setting while laying the groundwork for future work that could be the redefining building blocks of the Digital Workplace ecosystem. In a case study of one tech company that experienced a 35% boost in productivity, the article breaks down Salesforce's tools. It examines the challenges, such as data security and user adoption, relative to the solutions and concludes with an analysis of how AI can further enhance remote work environments.

description: A combined experimental and theoretical study of transition matrix elements of the 6p 2Pj - 8s 2S1/2 transition in atomic Cs is reported. Measurements of the polarization-dependent two-photon excitation spectrum associated with the transition were made in an approximately 200 cm-1 range on the low frequency side of the 6s 2S1/2 - 6p 2P3/2 resonance. The measurements depend parametrically on the relative transition matrix elements, but also are sensitive to far-off-resonance 6s 2S1/2 - np 2Pj - 8s 2S1/2 transitions. In the past, this dependence has yielded a generalized sum rule, the value of which is dependent on sums of relative two-photon transition matrix elements. In the present case, best available determinations from other experiments are combined with theoretical matrix elements to extract the ratio of transition matrix elements for the 6p 2Pj - 8s 2S1/2 (j = 1/2,3/2) transition. The resulting experimental value of 1.423(2) is in excellent agreement with the theoretical value, calculated using a relativistic all-order method, of 1.425(2).

 Comments. I have compared the male type and topotypic paratypes of these two species, side-by-side, and can see no specific differences between them. The coxopodites of both share the apical, tooth-like seta; apicomesal, fimbriate lobe with another tooth-like seta at its mesal base; two enlarged setae dorsomesally and another enlarged setae apicolaterally, and, small basomesal lobe with a few apical setae. The type localities are both in south-central Africa: S. delicata from the environs of Salisbury [now Harare] in Zimbabwe and S. pallida from about 600 miles north at Mpulungu at the south end of Lake Tanganyika in Zambia.

Geschlechtswechsel in der antiken Skulptur

description: Ausgangspunkt des Beitrags ist die große Gruppe von römischen Skulpturen, die ein griechisches Original im Großen und Ganzen getreu wiedergeben, es aber inhaltlich abwandeln, die sog. Umdeutungen. Wie weit der Spielraum reicht, der sich den Bildhauern bei diesem ambivalenten Umgang mit Statuen klassischer und hellenistischer Zeit bot, veranschaulichen einige Extremfälle, in denen nicht nur die Attribute und die Bekleidung des Originals verändert, sondern sogar das Genus transformiert worden ist. Zu solchen Schöpfungen kam es offenbar dann, wenn Bildhauer mit der Aufgabe konfrontiert waren, Statuen anzufertigen, für deren Kreation das einschlägige Repertoire an Abgüssen griechischer Originale nichts Passendes parat hielt, etwa eine weibliche Figur aus dem Gefolge des Bacchus oder ein Hirtenmädchen. Durch die Orientierung an einer im weitesten Sinn ›klassischen‹ Form war es möglich, beim Käufer den Eindruck zu erwecken, dass eine Statue trotz ungewöhnlichen Sujets auf einem Vorbild aus der Blütezeit der griechischen Kunst fußt. – Die Besprechung der Spezial-Umdeutungen bietet außerdem die Gelegenheit, die Überlieferung zweier äußerst beliebter statuarischer Typen des Dionysos vorzuführen, die in der Forschung so gut wie unbekannt geblieben sind. Den Abschluss bildet ein Ausblick auf die Transformation des Genus bei Statuen in sekundären Zusammenhängen, also in der Spät- und in der Nachantike.
description: The point of departure for this contribution is the large group of Roman sculptures that more or less faithfully reproduce a Greek original in form but alter its content, known as transformations. Just how much latitude sculptors had in the ambivalent use of statue types from Classical and Hellenistic times is illustrated by a few extreme cases in which not only the attributes and the attire of the original were changed, but even the gender was, too. These creations came about, it appears, when a sculptor was confronted with the task of making statues for which nothing suitable was available in the respective repertoire of casts of Greek originals, for instance a female figure from the retinue of Bacchus or a shepherdess. If he kept to forms that were classical in the broadest sense, the sculptor could give the customer the impression that a statue, despite its unusual subject, still derived from an archetype from the heyday of Greek art. Discussion of these special transformations, furthermore, offers an opportunity to exhibit two exceptionally popular statue types of Dionysos that have remained all but unknown in research. We conclude with a look forward to the transformation of gender in statues in secondary contexts, i.e. in late and post antiquity.

description: We have carried out a brown dwarf search over an area of 14' x 23' near the central portion of the Pleiades open cluster in five optical and near infrared bands (i', Z, J, H, Ks) with 10 sigma detection limits of i' = 22.0, J = 20.0 and Ks = 18.5 mag. The surveyed area has large extinction in excess of Av = 3 in the Pleiades region. We detected four new brown dwarf candidates from the colour-colour (J-K, i'-J) and the colour-magnitude (J, i'-K) diagrams. We estimated their masses as 0.046 Msun down to 0.028 Msun. The least massive one is estimated to have a mass smaller than Roque 25 or int-pl-IZ-69, and maybe the lowest mass object found so far in the Pleiades cluster.

description: Three parallel, manus-only sauropod trackways from the Coffee Hollow A-Male tracksite (Glen Rose Formation, Kendall County, Texas) were studied separately by researchers from the Heritage Museum of the Texas Hill Country and the Houston Museum of Natural Sciences. Footprint and trackway measurements generally show good agreement between the two groups’ data sets. Footprints appear to be shallowly impressed true tracks rather than undertracks. One of the Coffee Hollow trackways shows marked asymmetry in the lengths of paces that begin with the left as opposed to the right forefoot, and two of the Coffee Hollow trackways are unusually broad. The Coffee Hollow trackways differ enough from the manus portions of other Glen Rose Formation sauropod trackways to suggest that they were made by a different kind of sauropod. Greater differential pressure exerted on the substrate by the forefeet than the hindfeet probably explains the Coffee Hollow trackways, like other manus-only sauropod trackways, but the possibility that they indicate unusual locomotion cannot at present be ruled out.

description: We study the quench dynamics of a topologically trivial one-dimensional gapless wire following its sudden coupling to topological bound states. We find that as the bound states leak into and propagate through the wire, signatures of their topological nature survive and remain measurable over a long lifetime. Thus, the quench dynamically induces topological properties in the gapless wire. Specifically, we study a gapless wire coupled to fractionally charged solitons or Majorana fermions and characterize the dynamically induced topology in the wire, in the presence of disorder and short-range interactions, by analytical and numerical calculations of the dynamics of fractional charge, fermion parity, entanglement entropy, and fractional exchange statistics. In a dual effective description, this phenomenon is described by correlators of boundary changing operators, which, remarkably, generate topologically non-trivial monodromies in the gapless wire, both for abelian and non-abelian quantum statistics of the bound states.

description: The gonihedric spin model was first introduced as the action for a discretized tensionless string in a discretized embeding space. Afterwards was found that there are interesting features on the dynamical behavior of this model in 3 dimensions (as it was first formulated) that make us think on glassy spin model without inherent disorder. Extensive simulations have been carried out in the 3 dimensional model. In the following I will report on a work composed of two different but related parts. The first part is a numerical study through Monte Carlo simulations of the dynamical properties of the 2 dimensional version of the model (i.e. the loop model), which is much simpler due to the fact that it has trivial thermodynamical properties. The second part consists on an analytical approach of this 2 dimensional loop model coupled to gravity. We solve partially the associated two-matrix model via a reduction to an equivalent one matrix model and saddle point methods with the last one-matrix model.

description: In this paper, we propose a simple model referred as Contradistinguisher (CTDR) for unsupervised domain adaptation whose objective is to jointly learn to contradistinguish on unlabeled target domain in a fully unsupervised manner along with prior knowledge acquired by supervised learning on an entirely different domain. Most recent works in domain adaptation rely on an indirect way of first aligning the source and target domain distributions and then learn a classifier on a labeled source domain to classify target domain. This approach of an indirect way of addressing the real task of unlabeled target domain classification has three main drawbacks. (i) The sub-task of obtaining a perfect alignment of the domain in itself might be impossible due to large domain shift (e.g., language domains). (ii) The use of multiple classifiers to align the distributions unnecessarily increases the complexity of the neural networks leading to over-fitting in many cases. (iii) Due to distribution alignment, the domain-specific information is lost as the domains get morphed. In this work, we propose a simple and direct approach that does not require domain alignment. We jointly learn CTDR on both source and target distribution for unsupervised domain adaptation task using contradistinguish loss for the unlabeled target domain in conjunction with a supervised loss for labeled source domain. Our experiments show that avoiding domain alignment by directly addressing the task of unlabeled target domain classification using CTDR achieves state-of-the-art results on eight visual and four language benchmark domain adaptation datasets.

description: Safeguarding the services provided by marine forests inherently depends on an accurate understanding of macroalgal species diversity. Here, we provide the first DNA barcode survey of marine macroalgae from Norway, with a focus on the Bergen area, and compared our findings to morphological listings for the corresponding location. Specimens were sampled 14–20 April and 3–13 June 2016, and variously sequenced for several genetic markers, including the five prime end of the cytochrome c oxidase subunit I gene (COI-5P), elongation factor tufA, and the ribulose-1, 5-biphosphate carboxylase large subunit gene (rbcL). We generated 655 new barcode records for COI-5P, 11 for tufA, and 50 for rbcL, representing nine species of Chlorophyta, 51 species of Phaeophyceae, and 74 species of Rhodophyta. Sequence data confirmed the presence of 113 morphological species. A further 17 genetic groups indicated the presence of new species for the area, only six of which were linked to formally described species. The remaining four genetic records were uncertain in terms of morphological species assignment and relation to the local flora. We recommend further DNA barcoding surveys in the area, as only a third of the listed morphological species were genetically confirmed.

description: We present the second edition of the Sloan Digital Sky Survey (SDSS) Quasar Catalog. The catalog consists of 16713 objects in the SDSS First Data Release (DR1) that have luminosities larger than M_i=-22 (H_0=70 km/s, Omega_M=0.3, Omega_Lambda=0.7), have at least one emission line with FWHM larger than 1000 km/s, and have highly reliable redshifts. The area covered is ~1360 deg^2 and the redshifts range from 0.08 to 5.41, with a median value of 1.43. Each object has positions accurate to better than 0.2" rms per coordinate, five-band (ugriz) CCD-based photometry with typical accuracy of 0.03 mag, and information on the morphology and selection method, in addition to radio, near-infrared, and X-ray emission properties of the quasars, when available, from other large area surveys. Calibrated digital spectra covering 3800-9200 Angstroms at a spectral resolution 1800-2100, are available. This publication supersedes the first SDSS Quasar Catalog, which was based on material from the SDSS Early Data Release. A summary of corrections to current quasar databases is provided. The majority of the objects were found in SDSS commissioning data using a multicolor selection technique. Since the quasar selection algorithm was undergoing testing during the entire DR1 observational period, care must be taken when assembling samples for use in statistical studies. A total of 15786 objects (94%) in the catalog were discovered by the SDSS; 12,173 of which are reported here for the first time, including five quasars brighter than i=16.0 and 17 quasars with redshifts larger than 4.5.

Systematics of the GDR parameters are given and input parameters of different analytical models are discussed The experimental data are compared with theoretical calculations for even-even nuclei using criteria of minimum of both least-square value and root-mean-square deviation factor. Simple extensions of the models with energy-dependent widths to high gamma-ray energies $\gtrsim $ 30MeV which hold the energy-weighted sum rule for E1 gamma-transitions in good approximation are proposed and tested.

Subjects: 46 Information and Computing Sciences

description: We prove (non)convergence laws for random expansions of product structures. More precisely, we ask which structures U admit a limit law, saying that the probability that a randomly chosen expansion of Un satisfies a fixed first-order sentence always converges when n approaches infinity. For the groups Zn, where p is prime, we do indeed have such a limit law, even for the infinitary logic (Formula presented), and these probabilities always converge to dyadic rational numbers, whose denominator only depends on the expansion vocabulary. This can be used to prove that the Abelian group summation problem is not definable in (Formula presented). Further examples for structures with such a limit law are permutation structures and structures whose vocabulary only consists of monadic relations. As a negative example, we prove that the very simple structure ({0,1},≤) does not have a limit law. Furthermore, we develop a method based on positive primitive interpretations that allows transferring (non)convergence results to other structures. Using this method, we are able to prove that structures with binary function symbols or unary functions that are not interpreted by permutations do not have a limit law in general.

With the cross section and 5th dimension in the Planck region such tubes can be considered as string-like objects, namely $Δ-$strings. A model of attachment of $Δ-$string to a spacetime is offered. It is shown that the attachment point is a model of an electric charge for an observer living in the spacetime. Magnetic charges are forbidden in this model.

description: Multifrequency radio observations of the radio galaxy 3C459 using MERLIN, VLA and the EVN, and an optical HST image using the F702W filter are presented. The galaxy has a very asymmetric radio structure, a high infrared luminosity and a young stellar population. The eastern component of the double-lobed structure is brighter, much closer to the nucleus and is significantly less polarized than the western one. This is consistent with the jet on the eastern side interacting with dense gas, which could be due to a merged companion or dense cloud of gas. The HST image of the galaxy presented here exhibits filamentary structures, and is compared with the MERLIN 5-GHz radio map. EVN observations of the prominent central component, which has a steep radio spectrum, show a strongly curved structure suggesing a bent or helical radio jet. The radio structure of 3C459 is compared with other highly asymmetric, Fanaroff-Riley II radio sources, which are also good candidates for studying jet-cloud interactions. Such sources are usually of small linear size and it is possible that the jets are interacting with clouds of infalling gas that fuel the radio source.

description: Purpose: Arterial stiffness predicts cardiovascular complications. The association between arterial stiffness and blood lead (BL) remains poorly documented. We aimed to assess the association of central hemodynamic measurements, including pulse wave velocity (aPWV), with blood lead in a Flemish population. Materials and Methods: In this Flemish population study (mean age, 37.0 years; 48.3% women), 267 participants had their whole BL and 24-h urinary cadmium (UCd) measured by electrothermal atomic absorption spectrometry in 1985–2005. After 9.4 years (median), they underwent applanation tonometry to estimate central pulse pressure (cPP), the augmentation index (AI), pressure amplification (PA), and aPWV. The amplitudes of the forward (Pf) and backward (Pb) pulse waves and reflection index (RI) were derived by a pressure-based wave separation algorithm. Results: BL averaged 2.93 μg/dL (interquartile range, 1.80–4.70) and UCd 4.79 µg (2.91–7.85). Mean values were 45.0 ± 15.2 mm Hg for cPP, 24.4 ± 12.4% for AI, 1.34 ± 0.21 for PA, 7.65 ± 1.74 m/s for aPWV, 32.7 ± 9.9 mm Hg for Pf, 21.8 ± 8.4 mm Hg for Pb, and 66.9 ± 18.4% for RI. The multivariable-adjusted association sizes for a 2-fold higher BL were: +3.03% (95% confidence interval, 1.56, 4.50) for AI; −0.06 (−0.08, −0.04) for PA; 1.02 mm Hg (0.02, 2.02) for Pb; and 3.98% (1.71, 6.24) for RI (p ≤ .045). In 206 participants never on antihypertensive drug treatment, association sizes were +2.59 mm Hg (0.39, 4.79) for cPP and +0.26 m/s (0.03, 0.50) for aPWV. Analyses adjusted for co-exposure to cadmium were consistent. Conclusion: In conclusion, low-level environmental lead exposure possibly contributes to arterial stiffening and wave reflection from peripheral sites.

The approach is applicable to a wide range of data from physical measurements and numerical simulations. It is based on the well-known invariance of the Gaussian under linear operators, in particular differentiation. Instead of using a generic covariance function to represent data from an unknown field, the space of possible covariance functions is restricted to allow only Gaussian random fields that fulfil the homogeneous differential equation. The resulting tailored kernel functions lead to more reliable regression compared to using a generic kernel and makes some hyperparameters directly interpretable. For differential equations representing laws of physics such a choice limits realizations of random fields to physically possible solutions. Source terms are added by superposition and their strength estimated in a probabilistic fashion, together with possibly unknown hyperparameters with physical meaning in the differential operator.

 Graphipterus distinctus Péringuey (1898: 340) (Holotype, Transvaal, Lydenburg District, South African Museum).
 Diagnosis. Smaller adults, length 11–13 mm. Pattern of elytral vestiture distinctive (Figure 2), with the elytra covered in contrasting black and yellowish-grey pubescence. Basal half of elytron with a black linear band of pubescence along suture and a triangular patch of black pubescence completely surrounded by yellowish-grey pubescence; apical half of elytron predominantly covered in black pubescence but with a small ovate patch of yellowish-grey pubescence along the suture at apex, an angled median band of yellowish-grey pubescence which is contiguous with the patches of yellowish-grey pubescence on the basal half, and a narrow lateral band of yellowish-grey pubescence which connects the apical and median patches of yellowish-grey pubescence. The pronotal vestiture is likewise distinctive in that the median longitudinal band of black pubescence is more or less equal in width from base to apex. The shape of the patches of pubescence will readily separate individuals of this species from those of G. fasciatus, which has much more extensive areas of black pubescence on the elytra, and in which the median longitudinal band of dark pubescence on the pronotum becomes distinctly wider from base to apex (Figure 2). Small adults of G. ancora are also similar but that species is generally larger in body size (length 13–18 mm) and the elytral vestiture is coarser and more irregular (Figure 1).
 Distribution. Mozambique, Republic of South Africa (Limpopo and Mpumalanga Provinces), Swaziland. For a list of collecting localities see Basilewsky (1977: 93).
 Taxonomic Notes. This species was considered a subspecies of G. fasciatus by Burgeon (1929) and Basilewsky (1977) but the lack of any intergrade specimens between these two rather distinctive forms suggests that two separate species are indicated.

description: The quasi-isotropic inhomogeneous solution of the Einstein equations near a cosmological singularity in the form of a series expansion in the synchronous system of reference, first found by Lifshitz and Khalatnikov in 1960, is generalized to the case of a two-fluid cosmological model. This solution describes non-decreasing modes of adiabatic and isocurvature scalar perturbations and gravitational waves in the regime when deviations of a space-time metric from the homogeneous isotropic Friedmann-Robertson-Walker (FRW) background are large while locally measurable quantities like Riemann tensor components are still close to their FRW values. The general structure of the perturbation series is presented and the first coefficients of the series expansion for the metric tensor and the fluid energy densities and velocities are calculated explicitly.

description: Background and purpose — There are reports on perioperative deaths in cemented total hip arthroplasty (THA), and THA revisions are associated with increased mortality. We compared perioperative (intraoperatively or within 3 days of surgery), short-term and long-term mortality after all-cemented, all-uncemented, reverse hybrid (cemented cup and uncemented stem), and hybrid (uncemented cup and cemented stem) THAs. Patients and methods — We studied THA patients in the Norwegian Arthroplasty Register from 2005 to 2018, and performed Kaplan–Meier and Cox survival analyses with time of death as end-point. Mortality was calculated for all patients, and in 3 defined risk groups: high-risk patients (age ≥ 75 years and ASA > 2), intermediate-risk patients (age ≥ 75 years or ASA > 2), low-risk patients (age < 75 years and ASA ≤ 2). We also calculated mortality in patients with THA due to a hip fracture, and in patients with commonly used, contemporary, well-documented THAs. Adjustement was made for age, sex, ASA class, indication, and year of surgery. Results — Among the 79,557 included primary THA patients, 11,693 (15%) died after 5.8 (0–14) years’ follow-up. Perioperative deaths were rare (30/105) and found in all fixation groups. Perioperative mortality after THA was 4/105 in low-risk patients, 34/105 in intermediate-risk patients, and 190/105 in high-risk patients. High-risk patients had 9 (CI 1.3–58) times adjusted risk of perioperative death compared with low-risk patients. All 4 modes of fixation had similar adjusted 3-day, 30-day, 90-day, 3–30 day, 30–90 day, 90-day–10-year, and 10-year mortality risk. Interpretation — Perioperative, short-term, and long-term mortality after primary THA were similar, regardless of fixation type. Perioperative deaths were rare and associated with age and comorbidity, and not type of fixation.

description: Exotic species are non-native plants or animals that are introduced into areas where they do not naturally occur. Exotic species can out-compete natives by reproducing faster, competing for food and habitat more efficiently, and thrive in the absence of natural predators, and therefore widely expand their distribution range. In such cases, exotic species become invasive and can represent a major threat to global biodiversity, human health and lead to economic losses. South Africa has been subjected to many exotic introductions, some of which have established and became invasive such as the common starling (Sturnus vulgaris). Less than 20 individuals, native from the United Kingdom, were introduced to South Africa in the l890s. One century later, it has become invasive and it is found along the South African West and East Coast from Cape Town to Port Elizabeth. The objective of this study is to understand the population structure and dynamics in order to understand birds' dispersal and spread; two very important points for management and pest control. We sampled common starlings across their distribution in South Africa, and analysed them using microsatellite and mitochondrial data. For comparative purposes, we also included material from Namibia and the United Kingdom. In this study, we differentiate the native population (England) from the introduced population (South Africa-Namibia). Within the introduced range, the observed heterozygosity is of 0.613 compared to 0.698 for the native English population. Genetic differentiation (FST>0.032) between native and introduced has been observed, however no structure in sub-population within the South African population was highlighted. Within the South African population, the genetic similarity between individuals decrease with geographic distance, indicating an isolation-by-distance pattern. The mean average squared of parent-offspring distance (σ²) was estimate to varying between 2 and 10 km². Combination of microsatellites, mitochondrial data and GIS analysis permit to identified short and long distance dispersion in starling populations.

description: We discuss a systematic method of analytically calculating the asymptotic form of quasi-normal frequencies of a four-dimensional Schwarzschild black hole by expanding around the zeroth-order approximation to the wave equation proposed by Motl and Neitzke. We obtain an explicit expression for the first-order correction and arbitrary spin. Our results are in agreement with the results from WKB and numerical analyses in the case of gravitational waves.

description: Background: In the pubertal period, each part of the body grows at different rates. This makes the relationship between the parts nonlinear. Particularly, the fat mass (FM) of boys tends to decrease, further exacerbating the issue of linearity in growth. Aim: To propose predictive models of FM from skinfolds (SF) adjusted allometrically. Subjects and methods: 75 pubertal boys (14.4 ± 0.9 years) composed the sample by self-selected pubic hair. FM was determined by DXA (FMDXA) (kg), stature (cm), body mass (kg) and nine SF (mm) by anthropometric measurements. The SF were individually adjusted allometrically. FMDXA (Y) values and each anthropometric independent variable-IV (X) underwent logarithmic transformation. Linear regressions were used. The significance of the prediction of the FMDXA of each model (ANOVA) and the concordance analysis (Bland-Altman) were performed. Results: Predictive allometric models of FMDXA showed high determination coefficients (r2) and reduced standard errors of estimation (SEE). The adjusted model involved reduced agreement limits, demonstrating its accuracy. Conclusions: It was possible to propose models with allometric adjustments to estimate FM of pubertal boys. Allometry may aid in the development of predictive linear models of body composition, since it has an indicative capacity of the variables for estimation.

description: The paper deals with the equation $-Δu+a(x) u =|u|^{p-1}u $, $u \in H^1(\mathbb{R}^N)$, with $N\ge 2$, $p>1,\ p0$, $\lim_{|x| \to \infty} a(x)= a_\infty$. Assuming on the potential that $\lim_{|x| \to \infty}[a(x)-a_\infty] e^{η|x|}= \infty \ \ \forall η>0$ and $ \lim_{ρ\to \infty} \sup \left\{a(ρθ_1) - a(ρθ_2) \ :\ θ_1, θ_2 \in \mathbb{R}^N,\ |θ_1|= |θ_2|=1 \right\} e^{\tildeηρ} = 0 \mbox{ for some } \ \tildeη>0$, but not requiring any symmetry, the existence of infinitely many positive multi-bump solutions is proved. This result considerably improves those of previous papers [8,12,15,17,28].
FIFO Buffering Transceiver: A Communication Chip Set for Multiprocessor Systems
Creators: name: Ng, Charles H.
Publisher: name: California Institute of Technology
Year: 1982
Subjects: Computer Science

description: This thesis describes a family of VLSI chips designed to link a number of processors on a one-to-one basis. With these chips as communication system building blocks, a complex multiprocessor system can be built. Inter-processor communication within the multiprocessor system is accomplished by passing messages composed of data packets.

The resulting chip, called a First-in-first-out Buffering Transceiver (FIBT), provides a full duplex communication channel between any two processors. FIFO queues are provided for buffering data on each communication channel. FIBT accepts data packets from the host processor via a parallel data bus and serially sends them out to the destined processor. FIBT handshakes with the processor by using asynchronous interrupt signals.

Linkage between any two FIBTs is accomplished by using only two wires. Both data bits and handshaking signals are sent by these two lines. The FIBT system is neither a synchronous nor an asynchronous one; instead, it is an "one-clock-different-phases" system. A clock signal sets up the frequency reference; the start and stop bits set up the phase reference.

Finally, FIBT is implemented in nMOS technology. The design of the circuit is discussed in detail. The design is generalized enough so that data packets of various sizes can be handled. The layout of the chip is coded in an integrated circuit descriptive language. Any member of the family of chips can be obtained by changing three basic parameters. Techniques used in verifying the circuit are shown, and several observations about VLSI design are offered.
