description: The paper reports on the construction and testing of a Standard International Food Policy Research Institute (IFPRI) computable general equilibrium model for South Africa. A 1998 social accounting matrix (SAM) for South Africa is compiled using national accounts information and recently released supply-use tables. By updating to a recent year, and by distinguishing between producers and commodities, this SAM is an improvement on the existing SAM databases for South Africa. Furthermore, this SAM is made consistent with the requirements of IFPRI's standard comparative static computable general equilibrium (CGE) model. This model is then used to simulate the economy- wide impact of a range of hypothetical policy levers, including: increased government spending; the elimination of tariff barriers; and an improvement in total factor productivity. Results indicate that assumptions made regarding the mechanisms of macroeconomic adjustment are important in determining the expected impacts of these policies. Firstly, despite mixed results concerning changes in household income distribution, the impact of expansionary fiscal policy appears to be growth enhancing, with the Keynesian style adjustment mechanism producing the most positive results. Secondly, a complete abolition of import tariffs also appears to generate increases in gross domestic product, with negative and positive consequences for aggregate manufacturing and services respectively. Finally, an increase in total factor productivity is growth enhancing, with the most positive results derived under neoclassical assumptions of the macroeconomic adjustment mechanisms. These simulations are meant to demonstrate the usefulness for economy-wide policy modelling and the paper concludes by highlighting areas of policy analysis that might benefit from more detailed applications with this framework.
Toward verification of the Riemann hypothesis: Application of the Li criterion

description: We substantially apply the Li criterion for the Riemann hypothesis to hold. Based upon a series representation for the sequence \{λ_k\}, which are certain logarithmic derivatives of the Riemann xi function evaluated at unity, we determine new bounds for relevant Riemann zeta function sums and the sequence itself. We find that the Riemann hypothesis holds if certain conjectured properties of a sequence η_j are valid. The constants η_j enter the Laurent expansion of the logarithmic derivative of the zeta function about s=1 and appear to have remarkable characteristics. {\em On our conjecture}, not only does the Riemann hypothesis follow, but an inequality governing the values λ_n and inequalities for the sums of reciprocal powers of the nontrivial zeros of the zeta function.

description: There is a continuing debate about whether international trade is responsible for the observed skilled-unskilled wage gap. In this paper we present a general equilibrium trade model with differentiated goods. We begin with an analytical model and show how changes in relative factor returns can be decomposed into changes in commodity prices, changes in the trade balance, and changes in the factor endowment Then we use a computable general equilibrium (CGE) trade model calibrated to the U.S. economy in 1982 to analyze the effects of these shocks, as well as technology changes, observed in the U.S. in the 1980's.

The experimental data were corrected for the effects of multiple scattering, both in the center detector and in the neutron detectors. The final data at En = 12.0 MeV deviate considerably from the predictions of nucleon-nucleon phase-shift analyses and potential models. The impact of the new data on the value of the charged pion-nucleon coupling constant is discussed in a model study.

description: This paper analyzes two potential trade liberalization scenarios – a Free Trade Area of the Americas (FTAA) and possible links between MERCOSUR and the European Union (EU) – in a world computable general equilibrium (CGE) model. The model also incorporates some macro elements such as a cash- in-advance mechanism and rigidities in wages and exchange rates. The empirical results show that the two alternative regional integration scenarios are good for the participants while have little impact on the nonparticipants. Both scenarios are net trade creating, as trade creation greatly exceeds trade diversion, and the trade-diversion has relatively minor effects on the affected regions. The gains are larger for the Latin American participants than for their large potential partners – the U.S. and EU. These results are consistent with earlier studies of NAFTA, which also predicted small positive gains for the U.S. and large gains for Mexico. Many countries in Latin America are currently undergoing macroeconomic strains, and growth in the region has slowed. In this environment, external shocks and stabilization and structural adjustment programs are likely to lead to significant swings in trade balances and exchange rates. These issues will have to be considered in acknowledging that it is hard to reap the long-term benefits of trade liberalization in an environment of macroeconomic instability.
A Note on Productivity and Per Capita GDP Growth: the Role of the Forgotten Factors

Subjects: SECS-P/01 Economia politica

description: Average hourly productivity has often been used to draw conclusions on long run per capita GDP growth, based on the assumption of full utilization of labour resources. In this paper, we argue that a failure to recognize the
potentially significant wedges among the two variables – even in the long run - can be misleading. By applying both time series and panel cointegration techniques on data on 19 OECD countries, we fail to reject the hypothesis of absence of a long run common stochastic trend among the two variables in the period 1980-2005. Furthermore, we apply a simple decomposition of GDP growth into five variables, included some related to
the supply-side and demographics, so to verify the single contributions to income growth and variance over our period of interest. We conclude that variables that have been so far absent in the growth literature have indeed a
non-negligible role in explaining the dynamics of long run per capita GDP growth. In particular, these “forgotten factors” (that we identify with the employment and the activity rates and a demographic ratio) matter more in better performing economies, where we also highlight that productivity has been less important in determining GDP growth than in relatively bad performers.

description: We study the capture of light objects of arbitrary velocity by binary systems. Extending results for the capture of comets in the solar system, we develop a simple geometric characterization of the capture cross section, leading directly to the distribution of orbital parameters of captured objects. We use the same framework to study the lifetimes of these bound orbits prior to ejection, and find that a simplified version of the Öpik--Arnold approach readily yields a closed-form estimate for the ejection rate that agrees well with numerical experiments. Without any detailed-balance assumptions, our results make manifest the characteristics of close encounters leading to capture and ejection. As an application of our results, we demonstrate the estimation of the equilibrium population of captured dark matter particles in a binary system.

description: We present a new protocol in which a secret multiqubit quantum state $\ketΨ$ is shared by $n$ players and $m$ controllers, where $\ketΨ$ is the encoding state of a quantum secret sharing scheme. The players may be considered as field agents responsible for carrying out a task, using the secret information encrypted in $\ketΨ$, while the controllers are superiors who decide if and when the task should be carried out and who to do it. Our protocol only requires ancillary Bell states and Bell-basis measurements.

description: We present the discovery of the optical afterglow of GRB 050505 and an optical absorption spectrum obtained with the Keck I 10-m telescope. The spectrum exhibits three redshifted absorption systems with the highest, at z=4.2748, arising in the GRB host galaxy. The host absorption system is marked by a damped Ly-alpha (DLA) feature with a neutral hydrogen column density of logN(HI)=22.05+/-0.10, higher than that of any QSO-DLA detected to date, but similar to several other recent measurements from GRB spectra. In addition, we detect absorption lines from both low- and high-ionization species from which we deduce a metallicity, Z~0.06 Z_solar, with a depletion pattern that is roughly similar to that of the Galactic warm halo, warm disk, or disk+halo. More importantly, we detect strong absorption from SiII* indicating a dense environment, n_H>10^2 cm^-3, in the vicinity of the burst, with a size of about 4 pc. In addition, the CIV absorption system spans a velocity range of about 1000 km/s, which is not detected in any other absorption feature. We show that the most likely interpretation for this wide velocity range is absorption in the wind from the progenitor star. In this context, the lack of corresponding SiIV absorption indicates that the progenitor had a mass of <25 M_solar and a metallicity <0.1 Z_solar, and therefore required a binary companion to eject its hydrogen envelope prior to the GRB explosion. Finally, by extending the GRB-DLA sample to z~4.3 we show that these objects appear to follow a similar metallicity-redshift relation as in QSO-DLAs, but with systematically higher metallicities. It remains to be seen whether this trend is simply due to the higher neutral hydrogen columns in GRB-DLAs, or if it is a manifestation of different star formation properties in GRB-DLAs. [abridged]

An Evaluation of Four Retarding Admixtures in Structural Concrete

Publisher: name: Kentucky Transportation Center, University of Kentucky
Year: 1962
Subjects: subject: Transportation Engineering

description: Early in 1960, the Construction Division was becoming quite concerned with the growing problem of obtaining satisfactorily smooth reinforced concrete bridge decks. Increasing areas of new decks were not measuring up to requirements when checked with a straight-edge, and rough-riding surfaces were resulting even after corrective grinding. It appeared that, on large pours, perhaps more time for placing and finishing was needed; this was so particularly on hot, windy days when ambient conditions would cause the concrete to set more rapidly. A proposed method of providing more working time was to use retarding admixtures to slow the setting time of the concrete.

description: We study the asymptotic dynamics for solutions to a system of nonlinear Schrödinger equations with cubic interactions, arising in nonlinear optics. We provide sharp threshold criteria leading to global well-posedness and scattering of solutions, as well as formation of singularities in finite time for (anisotropic) symmetric initial data. The free asymptotic results are proved by means of Morawetz and interaction Morawetz estimates. The blow-up results are shown by combining variational analysis and an ODE argument, which overcomes the unavailability of the convexity argument based on virial-type identities.

Publisher: name: Kentucky Transportation Center, University of Kentucky
Year: 1962
Subjects: subject: Transportation Engineering

description: Initial surface treatments of so-called traffic-bound macadam rural secondary roads presents a challenging but frustrating problem in the over-all highway program. In many cases, these roads do not merit the expenditures that would be needed to construct the type of pavement desired, yet there is a need for a dust-free, all-weather type of surface for these roads. It may be argued, for instance, that initial surfacing should be deferred until such time that the construction of a proper base and surface would be justified. On the other hand, one might argue that even a light surfacing would be preferred despite the fact that expensive maintenance might be incurred subsequently. Notwithstanding these or other persuasive arguments, initial treatment work comprises an engrossing proportion of the highway program.

description: We consider the final-state problem for the nonlinear Schrödinger equations (NLS) with a suitable time-decaying harmonic oscillator. In this equation, the power of nonlinearity $|u|^ρu $ is included in the long-range class if $0 < ρ\leq 2/(n(1- λ)) $ with $0 \leq λ<1/2$, which is determined by the harmonic potential and a coefficient of Laplacian. In this paper, we find the final state for this system and obtain the decay estimate for asymptotics.

description: Tissue-culture propagated "Chicksaw" blackberry plants were set four feet apart in April of 2000 as part of a five-year trellising trial near Reidsville, Georgia. There were five treatments: an untrellised control, posts with plastic baling string on both sides, posts and three vertical wires, "raspberry" V trellis, and Limited Arm-Rotation Shift-Trellis (eliminated in 2003). There were four replications with twenty feet for each treatment per replication, for a total of 80 feet per treatment. Primocanes were tipped at 3.5 to four feet and re-tipped several times during the summer when new growth exceeded about 12 inches. Mature plant height at the end of the growing season was about five feet. Starting in the third growing season, yield data was collected from a ten-foot section of each replication. The highest-yielding trellis systems over a three-year period were Post and String and Raspberry V. The Post and String was an inexpensive trellis system, but it was more difficult to remove primocanes. The Raspberry V trellis offered advantages for management and PYO harvest. The Post and Wire trellis yields were not impressive, but it was easier to find all the ripe fruit for distant shipping.

Deja vu : an overview of 20th century adult education in British Columbia as reported by the mainstream press
Creators: name: Stamm, Raimund Robert
Publisher: name: University of British Columbia
Year: 2009

description: Problem: With a few notable exceptions, the history of adult education in British Columbia has received relatively little attention. What information there is, is often confined to somewhat narrow time frames, locations, or topics. A general overview of the history of adult education in British Columbia during the 20th century seems to be lacking. This study is a modest attempt to begin adding voice to this important but largely overlooked area. Conceptual Approach: The approach taken is one of historical review. The study, while to some degree quantitative, is much more interested in the qualitative aspects of the material examined. Newspapers, which the author suggests provide a unique historical record, serve as the sole source of data. Methodology: The B.C. Legislative Library Newspaper Index from 1900 -1999 is the source of documents for this study. A thorough reading of all newspaper articles (550+), cited as being related to adult education, was undertaken. Articles were grouped by decade and recorded. Within the decades certain themes were identified and also recorded. Two specific themes (lifelong learning and distance education) received special attention and were examined and recorded separately. Findings: There are a number of reoccurring themes that arise during the period examined. Many of these themes have a direct correlation to issues facing adult education today. These issues include, but are not limited to: • lifelong learning • distance education and related educational technology • duplication of services • libraries and adult education • defining/purpose(s) adult education. Since these and other issues are part of the current discourse about adult education, it seems reasonable that lessons learned/not learned in the past not be forgotten. With the benefit of historical hindsight, which includes sources that are not confined to potentially narrow interests, adult educators may become better informed by considering these issues.

description: We present an analysis of a Chandra ACIS-I observation of the massive galaxy cluster A644. This cluster was previously classified as a cooling flow, but no radio emission has been detected from its cD galaxy. Outside the core (R ~75 kpc ~0.03R_vir) the hot ICM has properties consistent with a (relaxed) cool-core cluster out to the largest radii investigated (R ~415 kpc ~0.14 R_vir). Over this region the gravitating mass profile is described well by a Navarro-Frenk-White profile with concentration parameter, c = 6.1 +/- 1.2, and virial radius, R_vir = 2.9 +/- 0.4 Mpc. However, inside the core the temperature and entropy profiles reverse their inward radial decline and rise at the center; the inner temperature profile is inconsistent with a constant at the 2.3 sigma level. Although the core region does not display X-ray cavities or filamentary structures characteristic of radio-loud, cool-core clusters, the peak of the X-ray emission is offset from that of the centroid of the global X-ray halo by ~60 kpc. The position of the cD galaxy lies approximately between the X-ray peak and centroid, further testifying to a merger origin for the properties of the X-ray emission in the core. We discuss the implications of A644 and the small number of radio-quiet, cool-core clusters for the AGN feedback paradigm to suppress cooling flows in clusters.

description: We propose the approximate Laplace approximation (ALA) to evaluate integrated likelihoods, a bottleneck in Bayesian model selection. The Laplace approximation (LA) is a popular tool that speeds up such computation and equips strong model selection properties. However, when the sample size is large or one considers many models the cost of the required optimizations becomes impractical. ALA reduces the cost to that of solving a least-squares problem for each model. Further, it enables efficient computation across models such as sharing pre-computed sufficient statistics and certain operations in matrix decompositions. We prove that in generalized (possibly non-linear) models ALA achieves a strong form of model selection consistency for a suitably-defined optimal model, at the same functional rates as exact computation. We consider fixed- and high-dimensional problems, group and hierarchical constraints, and the possibility that all models are misspecified. We also obtain ALA rates for Gaussian regression under non-local priors, an important example where the LA can be costly and does not consistently estimate the integrated likelihood. Our examples include non-linear regression, logistic, Poisson and survival models. We implement the methodology in the R package mombf.

Description
Specimen TUG 939-75 is a fragment of a phragmocone with parts of the outer shell preserved. The conch surface is smooth. The conch cross section is circular. The conch has a height of 33–34 mm at a length of 46 mm (angle of expansion = 1.2°). At the conch height of 34 mm the chamber length is 7 mm (RCL = 0.21). The siphuncle is marginally positioned with a diameter of 16 mm where the conch height is 34 mm. The septal necks are holochoanitic and form siphuncular segments, which have in longitudinal view slightly concave outlines (Fig. 5C). The siphuncle is filled with a massive sparitic infill, which preserved no details of the internal structure of the endosiphuncular deposits.
Remarks
The specimen can be identified as a C. regulus based on its large marginal siphuncle and its holochoanitic septal necks.

The weekly-featured advertisements were measured in square inches and the different advertisement placements within the weekly flier included front, back, or within pages. A non-linear Almost Ideal Demand System was used to model the share equations for Gala apples, Fuji apples, Red Delicious apples, Granny Smith apples, other sweet apples, other tart apples, pears, bananas, oranges, and grapes. One hundred thirty-five weeks of data on weekly store sales were collected from two grocery stores in the Portland, Oregon metropolitan area. Results from the advertised feature fliers and placement measures indicate the importance of retail management in determining demand levels.

description: Just as international food and agricultural trade has increased over time, food safety has become increasingly important. This paper discusses the economic framework of food safety and international food trade. Both the private and public sectors within individual countries have incentives to improve food safety, and as a result they have taken many actions to reduce food-safety risks, often in the form of private, national, and international standards that they impose of firms. The first half of this article discusses these issues. Differences in standards across borders can lead to trade conflicts whose resolutions depend on the distribution of costs and benefits from the manufacture, trade, and consumption of safe food. The second half of this article presents a framework of three main types of international outcomes arising from differing food-safety standards, with examples from both the public and private sectors.

description: We analyse the point-symmetric planetary nebula NGC 6309 in terms of its three-dimensional structure and of internal variations of the physical conditions to deduce the physical processes involved in its formation. We used VLA-D 3.6-cm continuum, ground-based, and HST-archive imaging as well as long slit high- and low-dispersion spectroscopy. The low-dispersion spectra indicate a high excitation nebula, with low to medium variations of its internal physical conditions. In the optical images, the point-symmetric knots show a lack of [NII] emission as compared with similar features previously known in other PNe. A rich internal structure of the central region is seen in the HST images, resembling a deformed torus. Long slit high-dispersion spectra reveal a complex kinematics in the central region. The spectral line profiles from the external regions of NGC 6309 indicate expanding lobes (~40 km/s) as those generally found in bipolar nebulae. Finally, we have found evidence for the presence of a faint halo, possibly related to the envelope of the AGB-star progenitor. Our data indicate that NGC 6309 is a quadrupolar nebula with two pairs of bipolar lobes whose axes are oriented PA=40 and PA=76. Equatorial and polar velocities for these two pairs of lobes are 29 and 86 km/s for the bipolar system at PA=40 and 25 and 75 km/s for the bipolar system at PA=76. There is also a central torus that is expanding at 25 km/s. Kinematical age for all these structures is around 3700 to 4000 yr. We conclude that NGC 6309 was formed by a set of well-collimated bipolar outflows (jets), which were ejected in the initial stages of its formation as a planetary nebula. These jets carved the bipolar lobes in the previous AGB wind and their remnants are now observed as the point-symmetric knots tracing the edges of the lobes.

description: In $d$ dimensions, the model for a massless $p$-form in curved space is known to be a reducible gauge theory for $p>1$, and therefore its covariant quantisation cannot be carried out using the standard Faddeev-Popov scheme. However, adding a mass term and also introducing a Stueckelberg reformulation of the resulting $p$-form model, one ends up with an irreducible gauge theory which can be quantised à la Faddeev and Popov. We derive a compact expression for the massive $p$-form effective action, $Γ^{(m)}_p$, in terms of the functional determinants of Hodge-de Rham operators. We then show that the effective actions $Γ^{(m)}_p$ and $Γ^{(m)}_{d-p-1}$ differ by a topological invariant. This is a generalisation of the known result in the massless case that the effective actions $Γ_p$ and $Γ_{d-p-2}$ coincide modulo a topological term. Finally, our analysis is extended to the case of massive super $p$-forms coupled to background ${\cal N}=1$ supergravity in four dimensions. Specifically, we study the quantum dynamics of the following massive super $p$-forms: (i) vector multiplet; (ii) tensor multiplet; and (iii) three-form multiplet. It is demonstrated that the effective actions of the massive vector and tensor multiplets coincide. The effective action of the massive three-form is shown to be a sum of those corresponding to two massive scalar multiplets, modulo a topological term.

description: Encouraging people to use their resources to purchase more fruits and vegetables is often at the top of the list of topics addressed by nutrition educators. Still, most populations are not consuming nearly enough fruits and vegetables according to a 2003 FAO/WHO Expert Report on Diet, Nutrition, and the Prevention of Chronic Diseases. This is particularly troubling given the surge of new research suggesting that fruits and vegetables can help prevent nutrient-deficiency disorders and also reduce the risk of cardiovascular diseases and cancer. Low-income individuals and households tend to spend less on and consume fewer fruits and vegetables than do their higher-income counterparts. A survey by the Economic Research Service (2004) shows that 19% of low-income households bought no fruits and vegetables from grocery stores over a two-week period, compared to only 10% of high-income households. A number of factors affect fruit and vegetable consumption, including accessibility, affordability, lack of motivation to eat more, cost, and specific preferences. Data gathered from 176 low-income individuals residing in Middle Tennessee showed that consumption of both fruits and vegetables by limited-resource individuals was well below the recommended intake. Thus it is of continuing interest to researchers to determine the reasons of potential reasons for this finding. The purpose of this study was to assess the availability of fruits and vegetables in stores which were easily accessible to the participants in the dietary-intake study. In-person surveys were conducted at fifty stores that were within a one-mile radius of five food banks to determine which fruits and vegetables were available in each and the quality of those that were present. These stores included any that was listed as a grocery store in a computer database, regardless of the size of the store. A large percentage of the stores had no fresh fruits or vegetables available. Most sold canned, while only a few had frozen fruits or vegetables. The fresh fruits that were most often available included apples, bananas, and lemons. Lettuce and cabbage were the most commonly available fresh vegetables. The variety of canned items was greater, with green beans being the mostly widely available. It is concluded that more fresh produce should be offered in stores that are in areas of easy accessibility to low-income neighborhoods. It is also recommended that a follow-up study be done to compare the prices of the items available, and whether increasing their presence in the local grocery stores leads to increased consumption.

description: Electricity consumed by residential consumers counts for a significant part of global electricity consumption and utility companies can collect high-resolution load data thanks to the widely deployed advanced metering infrastructure. There has been a growing research interest toward appliance load disaggregation via nonintrusive load monitoring. As the electricity consumption of appliances is directly associated with the activities of consumers, this paper proposes a new and more effective approach, i.e., activity disaggregation. We present the concept of activity disaggregation and discuss its advantage over traditional appliance load disaggregation. We develop a framework by leverage machine learning for activity detection based on residential load data and features. We show through numerical case studies to demonstrate the effectiveness of the activity detection method and analyze consumer behaviors by time-dependent activity modeling. Last but not least, we discuss some potential use cases that can benefit from activity disaggregation and some future research directions.

Diagnosis
Orthocones with a slightly depressed conch cross section; angle of expansion less than 5°; ornamented with fine transverse striae; sutures directly transverse, ca. seven chambers occur on a distance similar to the conch cross section; siphuncular diameter up to 0.5 of corresponding conch cross section; siphuncle marginal, in contact with shell wall; siphuncular segments slightly concave in longitudinal view; septal necks holochoanitic. (Adopted from Balashov 1968.)
Type locality and horizon
Kõrgesaare, Hiiumaa Island, Estonia; Vormsi Regional Stage, late Katian, Ordovician.
Material examined
One specimen (NRM Mo 152350) from Ostbjörka, Dalarna, Boda Limestone; late Katian, Late Ordovician.
Description
The specimen is a portion of a phragmocone with a diameter of 72 mm and marginally positioned siphuncle 31 mm in diameter (ca. 0.43 of the corresponding conch cross section). Directly transverse septa are 18 mm apart (0.25 of the conch cross section). The conch surface is ornamented with irregularly spaced, widely rounded striae, and in parts a faint, narrowly spaced shallow longitudinal striation is also visible.
Remarks
The specimen described herein was first described and figured as Orthoceras turris Angelin in Angelin & Lindström, 1880; it is the only known specimen of this species. The specimen agrees in general conch shape and in ornamentation with C. regulus. The species C. regulus is based on a type from the Vormsi Formation, in which the shell preservation is poor compared with that of the Boda Limestone and faint details of the ornamentation are not preserved. Therefore, the faint longitudinal striation found in the specimen from the Boda Limestone is regarded here as a character that does not justify the distinction of two species, and O. turris is interpreted as a junior synonym of C. regulus.
Comparison
Endoceras landerense Foerste, 1935 is comparable to Cameroceras regulus with respect to the angle of expansion, chamber height and position and relative diameter of the siphuncle, but the details of the ornamentation of this species are not known.
Stratigraphic and geographic range
Vormsi Regional Stage, Estonia (Balashov 1968), late Katian; Boda Limestone, late Katian, Siljan District, Sweden.

description: "High-income" households in China had per-capita disposable incomes of just $2,637 during 2003, but their ownership of consumer durable goods suggests a standard of living putting them in the "middle class." Their expenditures on food away from home were sharply higher than those of other urban households. Quantities of beverages, dairy products, and poultry products purchased for at-home consumption were also significantly higher, but purchases of most other food products were only marginally higher. Higher per-unit expenditures for most items reflect greater demand for quality by high-income households.

description: The quantum state overlap is the textbook measure of the difference between two quantum states. Yet, it is inadequate to compare the complex configurations of many-body systems. The problem is inherited by the widely employed quantum state fidelity and related distances. We introduce the weighted distances, a new class of information-theoretic measures that overcome these limitations. They quantify how hard it is to discriminate between two quantum states of many particles, factoring in the structure of the required measurement apparatus. Therefore, they can be used to evaluate both the theoretical and the experimental performances of complex quantum devices. We also show that the newly defined "weighted Bures length" between the input and output states of a quantum process is a lower bound to the experimental cost of the transformation. The result uncovers an exact quantum limit to our ability to convert physical resources into computational ones.

description: We report on analysis of the poorly studied source 2RXP J130159.6-635806 at different epochs with ASCA, Beppo-SAX, XMM-Newton, and INTEGRAL. The source shows coherent X-ray pulsations at a period ~700s with an average spin up rate of about dnu/dt ~ 2x10^{-13} Hz/s. A broad band (1-60 keV) spectral analysis of 2RXP J130159.6-635806 based on almost simultaneous XMM-Newton and INTEGRAL data demonstrates that the source has a spectrum typical of an accretion powered X-ray pulsar, i.e. an absorbed power law with a high energy cut-off with a photon index Gamma ~ 0.5-1.0 and a cut-off energy of ~25 keV. The long term behaviour of the source, its spectral and timing properties, tend to indicate a high mass X-ray binary with Be companion. We also report on the identification of the likely infrared counterpart to 2RXP J130159.6-635806. The interstellar reddening does not allow us to strongly constrain the spectral type of the counterpart. The latter is, however, consistent with a Be star, the kind of which is often observed in accretion powered X-ray pulsars.
