Spin-down of Relativistic Stars with Phase Transitions and PSR J0537-6910

description: Using a highly accurate numerical code, we study the spin down of rotating relativistic stars, undergoing a quark deconfinement phase transition. Such phase transitions have been suggested to yield an observable signal in the braking index of spinning-down pulsars, which is based on a ``backbending'' behaviour of the moment of inertia. We focus on a particular equation of state that has been used before to study this behaviour, and find that for the population of normal pulsars the moment of inertia does not exhibit a backbending behaviour. In contrast, for supramassive millisecond pulsars a very strong backbending behaviour is found. Essentially, once a quark core appears in a spinning-down supramassive millisecond pulsar, the star spins up and continues to do so until it reaches the instability to collapse. This strong spin-up behaviour makes it easier to distinguish a phase transition in such pulsars: a negative first time-derivative of the rotational period suffices and one does not have to measure the braking index. In the spin-up era, the usually adopted spin-down power law fails to describe the evolution of the angular velocity. We adopt a general-relativistic spin-down power law and derive the equations that describe the angular velocity and braking index evolution in rapidly rotating pulsars.

description: We analyze the quantitative labor market and aggregate effects of a carbon tax in a framework with pollution externalities and equilibrium unemployment. Our model incorporates endogenous labor force participation and two margins of adjustment influenced by carbon taxes: firm creation and green production-technology adoption. A carbon-tax policy that reduces carbon emissions by 35 percent - roughly the emissions reductions that will be required under the Biden Administration's new commitment under the Paris Agreement - and transfers the tax revenue to households generates mild positive long-run effects on consumption and output; a marginal increase in the unemployment and labor force participation rates; and an expansion in the number and fraction of firms that use green technologies. In the short term, the adjustment to higher carbon taxes is accompanied by gradual gains in output and consumption and a negligible expansion in unemployment. Critically, abstracting from endogenous firm entry and green-technology adoption implies that the same policy has substantial adverse short- and long-term effects on labor income, consumption, and output. Our findings highlight the importance of these margins for a comprehensive assessment of the labor market and aggregate effects of carbon taxes.

description: This study is concerned with assessing the contribution of the EU’s Common Agricultural Policy (CAP) to non-farm employment in the UK, through its direct and indirect effects on agriculture, up- and downstream industries, and the diversification of rural areas. We employ a micro approach, based on company data from FAME dataset combined with detailed subsidies data from DEFRA. We focus on employment in small and medium enterprises (SMEs) which are central for job creation. As a theoretical framework for our empirical firm employment function we employ a monopolistic competition model with delays in adjustment in prices, employment, and capacity. The generalised method of moments (GMM) is used to estimate the effect of CAP payments on both the level and growth of employment. Our estimation results suggest positive spillovers of CAP payments to non-farm employment. Although the magnitude of the effects is small, it is economically significant especially for the rural labour market.

description: The European Parliament’s Committee on Agriculture and Rural Development (COMAGRI) has recently drafted an own-initiative report “How Can the CAP Improve Job Creation in Rural Areas?” However, the creation or maintenance of jobs is not one of the CAP’s original (and still operational) objectives. Moreover, assessing the “success” or “failure” of the CAP in terms of job creation is a complex matter, particularly considering gross versus net job creation (including off-farm diversification by farm family members), or side-effects in the sense of job losses or gains in different sectors. How should agricultural economists address this topic, which is clearly of political importance but seems to require the reversal of long-term trends in EU agriculture? This paper suggests a number of questions, with a particular emphasis on the trade-off between employment and productivity, and the respective role of the two CAP Pillars. Some evidence from Ireland is presented to support the argument.

Gravitational wave bursts from cusps and kinks on cosmic strings

description: The strong beams of high-frequency gravitational waves (GW) emitted by cusps and kinks of cosmic strings are studied in detail. As a consequence of these beams, the stochastic ensemble of GW's generated by a cosmological network of oscillating loops is strongly non Gaussian, and includes occasional sharp bursts that stand above the ``confusion'' GW noise made of many smaller overlapping bursts. Even if only 10% of all string loops have cusps these bursts might be detectable by the planned GW detectors LIGO/VIRGO and LISA for string tensions as small as $G μ\sim 10^{-13}$. In the implausible case where the average cusp number per loop oscillation is extremely small, the smaller bursts emitted by the ubiquitous kinks will be detectable by LISA for string tensions as small as $G μ\sim 10^{-12}$. We show that the strongly non Gaussian nature of the stochastic GW's generated by strings modifies the usual derivation of constraints on $G μ$ from pulsar timing experiments. In particular the usually considered ``rms GW background'' is, when $G μ\gaq 10^{-7}$, an overestimate of the more relevant confusion GW noise because it includes rare, intense bursts. The consideration of the confusion GW noise suggests that a Grand Unified Theory (GUT) value $ G μ\sim 10^{-6}$ is compatible with existing pulsar data, and that a modest improvement in pulsar timing accuracy could detect the confusion noise coming from a network of cuspy string loops down to $ G μ\sim 10^{-11}$. The GW bursts discussed here might be accompanied by Gamma Ray Bursts.

description: Improving our understanding of risk and vulnerability is an issue of increasing importance for Ethiopia as it is for much of Africa. A small, but growing, body of evidence, points to the role that risk, shocks and vulnerability in perpetuating poverty. Specifically, uninsured shocks – adverse events that are costly to individuals and households in terms of lost income, reduced consumption, or the sale of destruction of assets – are a cause of poverty, Further, the threat of such events may cause households and individuals to take actions that, while providing some additional protection against shocks, come at the cost of income gains. The paper examines who is vulnerable to different types of shocks in rural Ethiopia. Using the two most recent rounds of the Ethiopian Rural Household Survey, it will characterize the nature, frequency, and severity of climatic, economic, health and other shocks faced by rural Ethiopian households. It will assess the impact of these on levels and changes in measures of household well-being such as food consumption, total consumption, asset holdings and poverty status between 1999 and 2004. To do so, it will draw on conditional convergence models of growth, but applied here at a micro level. The modeling framework will take changes in these outcomes as a function of the lagged outcome and other covariates, a model of conditional convergence. In such models, endogeneity of these lagged outcomes is a real concern. Our data from earlier rounds of the ERHS as well as shocks information on the period prior to 1999 will provide us with instruments and we will test for the validity of these used standard techniques. Further, the paper will explore the differential effects of these initial conditions and shocks by sub-groups based on location, demographic, and wealth characteristics. Doing so will indicate whether the speed of convergence is effected by transitory shocks and will illustrate what types of households are most vulnerable to different types of shocks.

description: Lamentably, the full analytical content of the epsilon-expansion of the master two-loop two-point function, with arbitrary self-energy insertions in 4-2epsilon dimensions, is still unknown. Here we show that multiple zeta values (MZVs) of weights up to 12 suffice through O(epsilon^9). Products of primitive MZVs are generated by a processes of "pseudo-exponentiation"" whose combinatorics faithfully accord with expectations based on Kreimer's modified shuffle product and on the Drinfeld-Deligne conjecture. The existence of such a mechanism, relating thousands of complicated rational numbers, enables us to identify precise and simple combinations of MZVs specific to quantum field theories in even numbers of spacetime dimensions.

description: An AOQ (acoustic-optic Q-switched) laser with cavityless weak-feedback configuration is demonstrated based on a Nd:GdVO4 bounce geometry. The laser can operate at a repetition up to 500 kHz with the output power above 4W. The pulse-width at 100 kHz reaches 5.2 ns, which is 4.3 times the round-trip time. A theory of Q-switched cavityless weak-feedback laser is proposed for the first time, to our best knowledge. This theory is very suitable for analyzing short pulses comparable to round-trip time. By utilizing the theory, simulation is implemented for our experimental conditions. The consistence between the simulation and the experimental results proves the validity of our theory.

It can be interpreted to describe the gravitational field of a rotating dyon, a particle endowed with both gravoelectric (mass) and gravomagnetic (NUT parameter) charge. Further, there also exists a duality relation between the two charges and the radial and the polar angle coordinates which keeps the solution invariant. The solution can however be transformed into the known Kerr - NUT solution indicating its uniqueness under the separability of equations of motion.

description: Application of the radial velocity (RV) technique in the near infrared is valuable because of the diminished impact of stellar activity at longer wavelengths, making it particularly advantageous for the study of late-type stars but also for solar-type objects. In this paper, we present the IGRINS RV open source python pipeline for computing infrared RV measurements from reduced spectra taken with IGRINS, a R ~ 45,000 spectrograph with simultaneous coverage of the H band (1.49--1.80 $\mu$m) and K band (1.96--2.46 $\mu$m). Using a modified forward modeling technique, we construct high resolution telluric templates from A0 standard observations on a nightly basis to provide a source of common-path wavelength calibration while mitigating the need to mask or correct for telluric absorption. Telluric standard observations are also used to model the variations in instrumental resolution across the detector, including a yearlong period when the K band was defocused. Without any additional instrument hardware, such as a gas cell or laser frequency comb, we are able to achieve precisions of 26.8 $\rm m\,s^{-1}$ in the K band and 31.1 $\rm m\,s^{-1}$ in the H band for narrow-line hosts. These precisions are empirically determined by a monitoring campaign of two RV standard stars as well as the successful retrieval of planet-induced RV signals for both HD 189733 and $\tau$ Boo A; furthermore, our results affirm the presence of the Rossiter-McLaughlin effect for HD 189733. The IGRINS RV pipeline extends another important science capability to IGRINS, with publicly available software designed for widespread use.

description: This paper uses farm-level data from Ireland to explore the impact of agricultural policies on the farm operators’ off-farm labour allocation decisions. The hypothesis that decoupled direct payments induce farmers to allocate more time to off-farm employment is tested. Despite earlier studies based Irish data finding evidence to support this hypothesis, the analysis presented here suggests that decoupled direct payments are significantly and negatively associated with both the probability and amount of time allocated to off-farm work. The potential relationship between farm income variability and off-farm employment decisions in the short and medium term for the case of Irish farm operators is also explored. The analysis identifies a positive association between farm income variability and off-farm employment in the medium term but no significant relationship in the short-term. This suggests that off-farm employment is part of a wider portfolio decision and the recent increases in farm income variability due to reforms of the Common Agricultural Policy, has induced farmers to work more off farm.

description: Saurornithoides Osborn, 1924
 TYPE SPECIES: Saurornithoides mongoliensis Osborn, 1924, by original designation.
 INCLUDED SPECIES: Only the type species is currently referred to Saurornithoides.
 LOCALITIES AND AGE: Saurornithoides is known with certainty only from the location of the holotype of Saurornithoides mongoliensis —Djadokhta Formation of Bayan Zag, upper Cretaceous of Mongolia (fig. 2).
 DIAGNOSIS: Differs from Zanabazar junior in its smaller overall size, lower number of teeth (108 versus 118), the presence of a jugal that is straight beneath the round orbit rather than curved, and the possession of a pneumatic recess on the lateral surface of the prootic dorsal to the trigeminal fenestra (the pneumatic recess is also absent in Troodon formosus). The maxillary teeth of Saurornithoides exhibit some increase in crown height posteriorly but to a lesser degree than in Zanabazar junior. Also in contrast to Zanabazar junior, the maxillary teeth of Saurornithoides lack replacement gaps. In these latter two characters, Saurornithoides agrees with Mei long, Sinovenator changii, and basal avialans among paravians, whereas Zanabazar junior is more similar to Byronosaurus jaffei and dromaeosaurs.
 COMMENT: The monophyly of Saurornithoides as historically recognized—including Saurornithoides mongoliensis and Saurornithoides junior —has not previously been questioned. A sister-taxon relationship between these two taxa, however, is difficult to support empirically. This may be due in part to the overall poor preservation of the holotype of Saurornithoides mongoliensis. Morphological disparity does exist between the known specimens of these two taxa and, although this list of differences is less than we might normally expect when taxonomically separating specimens at the generic level, the retention of junior in Saurornithoides implies a privileged relationship with mongoliensis that cannot currently be supported. The one polarized character previously considered to support the monophyly of mongoliensis + junior was the position of the facial foramen (CN VII) within the lateral depression of the braincase (Turner et al., 2007b). It now appears likely that this feature also is present in Troodon formosus and therefore is derived at a slightly more inclusive position on the troodontid tree (see below).

description: The majority of studies on rural migration in the EU have tended to focus rather on the scale and implications of exodus from rural societies than on rural areas as receivers of migrants, especially foreign ones. This research examines the foreign employment in the agricultural sectors of the selected countries as well as ‘pull’ and ‘push’ factors of foreign labour supply. It presents both positive and negative views on the process of rising inflow of foreign workers into rural areas that leads or can lead to reshaping the rural job markets, economies and communities. The theoretical background lies in economic, social and integrated theories and concepts of migration (political economy of migration, dual labour market theory, network theories, human capital models, relative deprivation theory etc.). The study is mainly devoted to migrant agricultural workers from Poland (being the largest source of post-accession migrants) in the UK (being second, after Germany, the most popular migrant destination for Polish-born citizens).

description: Using the next-nearest neighbor (zig-zag) Hubbard chain as an one dimemensional model, we investigate the influence of interactions on the position of the Fermi wavevectors with the density-matrix renormalization-group technique (DMRG). For suitable choices of the hopping parameters we observe that electron-electron correlations induce very different renormalizations for the two different Fermi wavevectors, which ultimately lead to a complete destruction of one section of the Fermi sea in a quantum critical point.

In the context of the NNPDF methodology, we implement a new efficient computing framework based on graph generated models for PDF parametrization and gradient descent optimization. The best model configuration is derived from a robust cross-validation mechanism through a hyperparametrization tune procedure.

description: Time Optimal Path Parametrization is the problem of minimizing the time interval during which an actuation constrained agent can traverse a given path. Recently, an efficient linear-time algorithm for solving this problem was proposed. However, its optimality was proved for only a strict subclass of problems solved optimally by more computationally intensive approaches based on convex programming. In this paper, we prove that the same linear-time algorithm is asymptotically optimal for all problems solved optimally by convex optimization approaches. We also characterize the optimum of the Time Optimal Path Parametrization Problem, which may be of independent interest.

description: Trinidad and Tobago is an exclusive producer of fine or flavour cocoa, which is produced from selected Trinitario genetic germplasm. This country participated in a Common Funds for Commodities/ International Cocoa Organisation/Bioversity Germplasm Project from 2000 to 2010. Twenty TSH clones (nine commercial types: TSH 730, 919, 1076, 1077, 1095, 1102, 1104, 1188 and 1220 and 11 TSH 1300 series) were evaluated over this period for growth, yield and disease resistance parameters in a replicated field trial located at La Reunion Estate, Centeno. Over the first three years significant differences were found between clones for survival rates in the field (X2 = 2.51, 38df P>0.001); field resistance to damage caused by the Cocoa Beetle, Steirastoma breve; presence or absence of vegetative brooms formed from Witches Broom Disease infection and precocity. A significant correlation (R2=-0.789; P=0.001) existed between girth and vigour for 3-year old trees. Dry bean yield data from 2003 to 2005 is presented, showing significant differences between cultivars, with TSH 730, 1076, 1330, 1344, 1350, 1347 and 1380 achieving 3-yr cumulative yields close to or exceeding 2 t ha-1. Cultivars with good yield and disease resistance traits are very discernible from this trial.

description: We study supersymmetric intersecting D6-branes wrapping 3-cycles in the Type IIA T^6/Z_4 orientifold background. As a new feature, the 3-cycles in this orbifold space arise both from the untwisted and the Z_2 twisted sectors. We present an integral basis for the homology lattice, H_3(M,Z), in terms of fractional 3-cycles, for which the intersection form involves the Cartan matrix of E8. We show that these fractional D6-branes can be used to construct supersymmetric brane configurations realizing a three generation Pati-Salam model. Via brane recombination processes preserving supersymmetry, this GUT model can be broken down to a standard-like model.

Zanabazar

description: Zanabazar, new genus
 TYPE SPECIES: Zanabazar junior (Barsbold, 1974).
DERIVATION OF NAME: In honor of Zanabazar (1635–1723), the first Bogd Gegen of Mongolia.
INCLUDED SPECIES: Type species only.
LOCALITY AND AGE: Nemegt Formation at Bugiin Tsav, Omnogov Aimag, Mongolia (figs. 2, 21). The Nemegt Formation overlies the Djadokhta Formation and is considered to be Maestrichtian based primarily upon the vertebrate fauna (Jerzykiewicz and Russell, 1991).
 DIAGNOSIS: Differs from Saurornithoides mongoliensis and most other troodontids (save Troodon formosus) in lacking a small depression on the lateral wall of the braincase just dorsal to the trigeminal foramen. The holotype of Zanabazar junior is the largest published troodontid specimen (midline length of the skull 5 272 mm), and is substantially larger than most other troodontid species. Only Troodon formosus appears to approach it in size. Differs from Troodon formosus in having a more ovoid-shaped foramen magnum, a posttemporal fenestra that is enclosed by an almost equal proportion of the exoccipital/opisthotic and squamosal (this same feature in Troodon formosus is formed almost entirely by the exoccipital/opisthotic), a deeper paroccipital process resulting in a different positon of the posttemporal fossa relative to the foramen magnum, and the lack of an osseous signature of the ophthalmic branch of the trigeminal nerve (CN V) in the laterosphenoid.

description: We report observations of coherent optical transition radiation interferometry (COTRI) patterns generated by microbunched ~200-MeV electrons as they emerge from a laser-plasma accelerator. The divergence of the microbunched portion of electrons, deduced by comparison to an analytical COTRI model, is ~6x smaller than the ~3 mrad ensemble beam divergence, while the radius of the microbunched beam, obtained from COTR images on the same shot, is < 3 microns. The combined results show that the microbunched distribution has estimated transverse normalized emittance ~0.5 mm mrad.

description: Charcoal briquettes are widely used in Trinidad and Tobago for outdoor recreational cooking. This study evaluated two invasive plant species Syzygium and Gliricidia as well as dry coconut husks as raw materials for charcoal briquettes. Samples were collected, dried and made into charcoal from a method adopted from MIT D-Lab. Cassava porridge was used as a binder for combining crushed charcoal samples into cylindrical briquettes using a manual mold and mechanical press. Each charcoal briquette sample was tested for burning time, ash content, calorific value, organic carbon, moisture content and phosphorus content. All three charcoal briquette samples displayed burning times of 2.5-3 hours, ash content 8-11%, calorific values 6100-6700 Kcal/Kg, organic carbon 2-4%, moisture content 10-16% and phosphorus < 1.5%. These results are comparable to briquettes sold commercially and validate further research into commercializing charcoal briquettes from the sample raw materials.

Zanabazar junior

description: Zanabazar junior (Barsbold, 1974)
HOLOTYPE: IGM 100 /1, a skull and partial mandible, six sacral and 11 caudal vertebrae, and the distal part of the right hind limb. The skull is largely complete except for the left and right quadrate, quadratojugal, ventral part of the lacrimal, palatine, pterygoid, and ectopterygoid, and the left squamosal, postorbital, and jugal, posterior part of the right jugal, and the postdentary bones other than the splenials. The posterior part of the left nasal is reconstructed in plaster, as are small parts of the left maxilla anterior to the maxillary fenestra and dorsal to the interfenestral bar. Plaster covers the ventral surface of the bones roofing the antorbital fenestra. The mandible comprises only the dentaries and splenials. The right hind limb includes the distal end of the tibia with the coossified astragalus and calcaneum, a distal tarsal, and the proximal ends of MT II–IV.
 TYPE LOCALITY AND AGE: As for Zanabazar.
 DIAGNOSIS: As for Zanabazar.
 REFERRED SPECIMENS: No new material of this species has been described, but two other troodontids have been described from the Nemegt Formation of Mongolia. Borogovia gracilicrus Osmólska, 1987, is known only from a partial hind limb from Altan Uul IV, and Tochisaurus nemegtensis Kurzanov and Osmólska, 1991, is known only from a metatarsus from the Nemegt area. Because the postcranial elements of Zanabazar junior do not include those parts diagnostic of the other two species, it is possible that one of the other two Nemegt Formation taxa is a junior synonym.
 COMMENTS: We chose to construct the name Zanabazar for Saurornithoides junior based on the morphological differences between the holotype and that of Saurornithoides mongoliensis and the questionable monophyly of Saurornithoides as defined by the sistertaxon relationship of S. mongoliensis and S. junior. This decision also was influenced by the common practice in phylogenetic analyses of assuming monophyly by compositely coding taxa (especially ‘‘genera’’). The differences between Zanabazar junior and Saurornithoides mongoliensis certainly merit coding these taxa separately. The temporal difference separating these specimens was not, and should not, be used to support taxonomic decisions.

description: The existence of compact gravitational lenses, with masses around 0.5 (M_{\odot}), has been reported in the halo of the Milky Way. The nature of these dark lenses is as yet obscure, particularly because these objects have masses well above the threshold for nuclear fusion. In this work, we show that they find a natural explanation as being the evolutionary product of the metastable false vacuum domains (the so-called strange quark nuggets) formed in a first order cosmic quark-hadron transition.
