description: This work is proposing the use of the geometry based on rectangular triangles, the varatio, in the study of the planning of Roman Torino, that is, of Augusta Taurinorum. It is known that the planning of Roman towns was based on the centuriation, a grid of parallel and perpendicular streets, where the two main axes were the Decumanus and the Cardo. By means of the varatio, the angle the Decumanus was forming with the east-west direction was given by the ratio of the catheti of a rectangular triangle. In the case of Torino, the town planning seems based on the ratio of catheti 1:2, which is giving an azimuth of the decumanus (Via Garibaldi) of 116,565° from true north. This value is in good agreement with the measurement of the direction of this street.
The saying and the doing: a survey of security and theft prevention measures in U.S. archives
Creators: name: Leab, Abigail
Publisher: name: University of British Columbia
Year: 2009

description: Although the principles and model practices of archival security are well known in the United States having been codified by the Society of American Archivists in the 1970s, little is known about archives' actual policies and their implementation. This study attempts to determine whether there is a dichotomy between principles and practice in the area of archival security. Analysis of the genesis of the SAA Archival Security Program and of its components (including the Register of Lost or Stolen Materials, the newsletter, the consultancy service, the model legislation), especially Timothy Walch's standard setting 1977 manual, as well as other historical events such as the Oberlin Conference on Theft not only illuminate the ideal principles with which to compare practices, but also reveal the reactive nature of the field. Examination of related literature from 1977 to the present demonstrates both trends concerning the topic and the need to make it part of everyday archival functions rather than debating whether it is part of disaster planning or preservation. It also establishes the contributions to the topic of archival security made by such activists as Philip P. Mason, Timothy Walch, Gregor Trinkaus-Randall and Richard Strassberg. The results of a questionnaire focusing on handling of materials and patrons demonstrates the gulf between the real and the ideal in various types of archives and examines how lack of staffing, budget and knowledge contribute to this gap. Finally, methods and practices are suggested for improvement of security awareness and methods. The willingness of the SAA to take a leadership role and to update of the components of the original Archival Security Program using new technology (such as the Internet) to create a centralized source of information for archivists struggling with balancing access and security is key. The work already started by the newly re-established SAA Security Roundtable needs to be built upon by the SAA's devoting financial and organizational support in order to make archival security a proactive and effective field. If that were to happen, the principles and the practice, the saying and the doing, could then become synonymous.

description: We have studied modulated inflation that generates curvature perturbation from light-field fluctuation. As discussed in previous works, even if the fluctuation of the inflaton itself does not generate the curvature perturbation at the horizon crossing, fluctuation of a light field may induce fluctuation for the end-line of inflation and this may lead to generation of cosmological perturbation ``at the end of the inflation''. Our scenario is different from those that are based on the fluctuations of the boundary of the inflaton trajectory, as clearly explained in this paper by using the $δN$ formalism. In this paper, we will consider the perturbation of the inflaton velocity that can be induced by a light field other than the inflaton. We also explain the crucial difference from the standard multi-field inflation model. We show concrete examples of the modulated inflation scenario in which non-gaussianity can be generated. We also discuss the running of the non-gaussianity parameter.

Towards Colour Flow Evolution at Two Loops

description: We calculate the two-loop and one-loop/one-emission contributions required for soft gluon evolution at the next-to-leading order. The colour structures are expressed in the colour flow basis, and the kinematic dependence and loop integrals are expressed in terms of multiple cuts and phase-space-like integrals. This directly allows to use them in the resummation of non-global observables and improved parton shower algorithms beyond the leading order and beyond the leading colour limit. Within the colour flow basis it becomes apparent that correlations beyond a dipole picture emerge even in colour-diagonal elements of the virtual corrections.

description: Spectral singularities and the coherent perfect absorption are two interrelated concepts that have originally been introduced and studied for linear waves interacting with complex potentials. In the meantime, the distinctive asymptotic behavior of perfectly absorbed waves suggests considering possible generalizations of these phenomena for nonlinear waves. Here we address perfect absorption of nonlinear waves by an idealized infinitely narrow dissipative potential modeled by a Dirac $δ$-function with an imaginary amplitude. Our main result is the existence of perfectly absorbed flows whose spatial amplitude distributions are asymmetric with respect to the position of the absorber. These asymmetric states do not have a linear counterpart. Their linear stability is verified numerically. The nonlinear waveguide also supports symmetric and constant-amplitude perfectly absorbed flows. The stability of solutions of the latter type can be confirmed analytically.

description: We present high-resolution infrared spectra of HL Tau, a heavily embedded young star. The spectra exhibit broad emission lines of hot CO gas as well as narrow absorption lines of cold CO gas. The column density for this cooler material (7.5+/-0.2 x 10^18 cm-2) indicates a large column of absorbing gas along the line of sight. In dense interstellar clouds, this column density of CO gas is associated with Av~52 magnitudes. However, the extinction toward this source (Av~23) suggests that there is less dust along the line of sight than inferred from the CO absorption data. We discuss three possibilities for the apparent paucity of dust along the line of sight through the flared disk: 1) the dust extinction has been underestimated due to differences in circumstellar grain properties, such as grain agglomeration; 2) the effect of scattering has been underestimated and the actual extinction is much higher; or (3) the line of sight through the disk is probing a gas-rich, dust-depleted region, possibly due to the stratification of gas and dust in a pre-planetary disk.

description: Recent measurements of neutron star mass from several candidates (PSR J$1614-2230$, PSR J$0348+0432$, MSP J$0740+6620$) set the lower bound on the maximum possible mass for this class of compact objects $\sim 2$ M$_\odot$. Existence of stars with high mass brings the possibility of existence of exotic matter (hyperons, meson condensates) at the core region of the objects. In this work, we investigate the (anti)kaon ($K^-, \bar{K}^0$) condensation in $β-$equilibrated nuclear matter within the framework of covariant density functional theory. The functionals in the kaonic sector are constrained by the experimental studies on $K^-$ atomic, kaon-nucleon scattering data fits. We find that the equation of state softens with the inclusion of (anti)kaon condensates, which lowers the maximum mass of neutron star. In one of the density-independent coupling cases, the $K^-$ condensation is through a first-order phase transition type, which produces a $2$ M$_\odot$ neutron star. The first-order phase transition results in mixed phase region in the inner core of the stars. While $\bar{K}^0$ condensation appears via second-order phase transition for all the models we consider here.

description: In a finite mixture of location-scale distributions maximum likelihood estimator does not exist because of the unboundedness of the likelihood function when the scale parameter of some mixture component approaches zero. In order to study the strong consistency of maximum likelihood estimator, we consider the case that the scale parameters of the component distributions are restricted from below by $c_n$, where $c_n$ is a sequence of positive real numbers which tend to zero as the sample size $n$ increases. We prove that under mild regularity conditions maximum likelihood estimator is strongly consistent if the scale parameters are restricted from below by $c_{n} = \exp(-n^d)$, $0 < d < 1$.

description: Polycrystalline CuMo$_{1-x}$W$_x$O$_4$ solid solutions were studied by resonant X-ray emission spectroscopy (RXES) at the W L$_3$-edge to follow a variation of the tungsten local atomic and electronic structures across thermochromic phase transition as a function of sample composition and temperature. The experimental results were interpreted using ab initio calculations. The crystal-field splitting parameter for the 5d(W)-states was obtained from the analysis of the RXES plane and was used to evaluate the coordination of tungsten atoms. Temperature-dependent RXES measurements were successfully employed to determine the hysteretic behaviour of the structural phase transition between the $α$ and $γ$ phases in CuMo$_{1-x}$W$_x$O$_4$ solid solutions on cooling and heating, even at low ($x$<0.10) tungsten content. It was found that tungsten ions have octahedral coordination for in the whole studied temperature range (90-420 K), whereas their coordination changes from tetrahedral to octahedral upon cooling for smaller ($x$ <= 0.15) tungsten content. Nevertheless, some amount of tungsten ions was found to co-exists in the octahedral environment at room temperature for $x$<0.15. The obtained results correlate well with the color change in these solid solutions.

description: We investigate the extinction curves of young galaxies in which dust is supplied from Type II supernovae (SNe II) and/or pair instability supernovae (PISNe). Since at high redshift (z>5), low-mass stars cannot be dominant sources for dust grains, SNe II and PISNe, whose progenitors are massive stars with short lifetimes, should govern the dust production. Here, we theoretically investigate the extinction curves of dust produced by SNe II and PISNe, taking into account reverse shock destruction induced by collision with ambient interstellar medium. We find that the extinction curve is sensitive to the ambient gas density around a SN, since the efficiency of reverse shock destruction strongly depends on it. The destruction is particularly efficient for small-sized grains, leading to a flat extinction curve in the optical and ultraviolet wavelengths. Such a large ambient density as n_H > 1 cm^{-3} produces too flat an extinction curve to be consistent with the observed extinction curve for SDSS J104845.05+463718.3 at z=6.2. Although the extinction curve is highly sensitive to the ambient density, the hypothesis that the dust is predominantly formed by SNe at z~6 is still allowed by the current observational constraints. For further quantification, the ambient density should be obtained by some other methods. Finally we also discuss the importance of our results for observations of high-z galaxies, stressing a possibility of flat extinction curves.

description: Superconducting single photon detectors (SSPD) based on nanopatterned niobium nitride wires offer single photon counting at fast rates, low jitter, and low dark counts, from visible wavelengths well into the infrared. We demonstrate the first use of an SSPD, packaged in a commercial cryocooler, for single photon source characterization. The source is an optically pumped, microcavity-coupled InGaAs quantum dot, emitting single photons on demand at 902 nm. The SSPD replaces the second silicon Avalanche Photodiode (APD) in a Hanbury-Brown Twiss interferometer measurement of the source second-order correlation function, g (2) (tau). The detection efficiency of the superconducting detector system is >2 % (coupling losses included). The SSPD system electronics jitter is 170 ps, versus 550 ps for the APD unit, allowing the source spontaneous emission lifetime to be measured with improved resolution.

 Diagnosis. Alisotrichia coclensis does not fit well into any of the species groups outlined by Olah and Flint (2012), but we tentatively assign it to the orophila group based on the lateral process of abdominal segment VIII bearing a pair of apical spines. The number of these spines varied among the specimens we examined. In some cases there are two on each side, in others there are three on a side, and some have two on one side and three on the other. The new species is most similar to A. cainguas Angrisano and Sganga from Argentina, but differs in lacking a ventromesal process from segment VII and in the antennae having both the scape and the flagellum greatly dilated.
 Description. Length 1.6–1.8 mm, 18 antennal segments, scape enlarged, pedicel elongate and covered with spatulate hairs, flagellum flattened and expanded, and color brown (in alcohol).
 Male genitalia. Abdominal segment VII annular, lacking a ventromesal process. Segment VIII expanded into posteromesal process, which bears 2-3 elongate spines, dorsolaterally with a short process bearing elongate thickened seta; in ventral view, the spines originate from lateral lobes; in dorsal view, segment VIII is produced anteriorly into a pair of finger-like processes, each bearing an elongate, thickened seta. Segment IX divided posteriorly, dorsal portion narrow and elongate, ventral portion rectanguloid, with a thin coiled process from upper surface, which curves downward distally, anteriorly narrowing to an elongate apodeme; in dorsal view rectanguloid, bilobed apically, laterally with elongate spines. Segment X a thin lobe in lateral view, dorsally short, rounded apically. Phallus tubular, narrowing at midlength, posterior margins rounded and lightly sclerotized, ejaculatory duct narrow protruding distally as small lobe.

description: Besides the well-known existence of Andreev bound states, the zero-energy local density of states at the boundary of a d-wave superconductor strongly depends on the boundary geometry itself. In this work, we examine the influence of both a simple wedge-shaped boundary geometry and a more complicated polygonal or faceted boundary structure on the local density of states. For a wedge-shaped boundary geometry, we find oscillations of the zero-energy density of states in the corner of the wedge, depending on the opening angle of the wedge. Furthermore, we study the influence of a single Abrikosov vortex situated near a boundary, which is of either macroscopic or microscopic roughness.

description: A probabilistic performance-oriented control design optimization approach is introduced for flight systems. Aiming at estimating rare-event probabilities accurately and efficiently, subset simulation is combined with surrogate modeling techniques to improve efficiency. At each level of subset simulation, the samples that are close to the failure domain are employed to construct a surrogate model. The existing surrogate is then refined progressively. In return, seed and sample candidates are screened by the updated surrogate, thus saving a large number of calls to the true model and reducing the computational expense. Afterwards, control parameters are optimized under rare-event chance constraints to directly guarantee system performance. Simulations are conducted on an aircraft longitudinal model subject to parametric uncertainties to demonstrate the efficiency and accuracy of this method.

description: Four-dimensional cosmological models are studied on a boundary of a five-dimensional Anti-de Sitter (AdS_5) black hole with AdS Reissner-Nordstrom and scalar charged Reissner- Nordstrom black hole solutions, where we call the former a "Hairless" black hole and the latter a "Hairy" black hole. To obtain the Friedmann-Robertson-Walker (FRW) spacetime metric on the boundary of the AdS_5 black hole, we employ Eddington-Finkelstein (EF) coordinates to the bulk geometry. We then derive modified Friedmann equations on a boundary of the AdS_5 black hole via AdS/CFT correspondence and discuss its cosmological implications. The late-time acceleration of the universe is investigated in our models. The contributions coming from the bulk side is treated as a dark energy source, and we perform MCMC analyses using observational data. Compared to the LCDM model, our models contain additional free parameters; therefore, to make a fair comparison, we use the Akaike information criterion (AIC) and the Bayesian information criterion (BIC) to analyze our results. Our numerical analyses show that our models can explain the observational data as reliable as the LCDM model does for the current data.

description: Stable, holomorphic vector bundles are constructed on an torus fibered, non-simply connected Calabi-Yau threefold using the method of bundle extensions. Since the manifold is multiply connected, we work with equivariant bundles on the elliptically fibered covering space. The cohomology groups of the vector bundle, which yield the low energy spectrum, are computed using the Leray spectral sequence and fit the requirements of particle phenomenology. The physical properties of these vacua were discussed previously. In this paper, we systematically compute all relevant cohomology groups and explicitly prove the existence of the necessary vector bundle extensions. All mathematical details are explained in a pedagogical way, providing the technical framework for constructing heterotic standard model vacua.

description: The response of a neo-Hookean fiber composite undergoing finite out-of-plane shear deformation is examined. To this end an explicit close form solution for the out-of-plane shear response of a cylindrical composite element is introduced. We find that the overall response of the cylindrical composite element can be characterized by a fictitious homogeneous neo-Hookean material. Accordingly, this macroscopic response is identical to the response of a composite cylinder assemblage. The expression for the effective shear modulus of the composite cylinder assemblage is identical to the corresponding expression in the limit of small deformation elasticity, and hence also to the expression for the Hashin-Shtrikman bounds on the out-of-plane shear modulus.

description: Magnetic field and temperature dependence of the Terahertz conductivity and permittivity of the colossal magnetoresistance manganite Pr_{0.65}Ca_{0.28}Sr_{0.07}MnO_3 (PCSMO) is investigated approaching the metal-to-insulator transition (MIT) from the insulating side. In the charge-ordered state of PCSMO both conductivity and dielectric permittivity increase as function of magnetic field and temperature. Universal scaling relationships between the changes in permittivity and conductivity are observed in a broad range of temperatures and magnetic fields. Similar scaling is also seen in La_{1-x}Sr_xMnO_3 for different doping levels. The observed proportionality points towards the importance of pure ac-conductivity and phononic energy scale at MIT in manganites.

The social dynamics of forest land policy in Vietnam: a case study of Lang Beo village
Creators: name: Carr, Kimberly Ann
Publisher: name: University of British Columbia
Year: 2009

description: Vietnam's 1993 land law gave land-use rights to individuals to improve forest management by allowing individuals to reap the benefit of their work while managing the land within government regulations. This thesis analyses the impacts of forest land policy on livelihood security, forest protection, and gender equity, and considers the future challenges facing people in a specific village. The general research method is a case study of an ethic minority group, in a rural, primarily subsistence village, in northern Vietnam. The specific research methods included: 8 weeks of field observation, 4 participatory rural appraisal activities, 20 in-depth interviews with 8 key informants, 12 sample household interviews, and 20 semi-structured interviews. This thesis shows that privatising forest land has had a negative socio-economic impact on poor people in the village, placing their livelihood security at greater risk. This negative impact is primarily attributable to the inequity of the forest land allocation process and the outcome of the allocation, as well as vague and inconsistent policies. The land allocation policy and government afforestation programs have helped increase the amount of trees planted and reduce the amount of forest exploitation the farmer does on his/her own land; however, it has contributed to new socio-economic problems. Growing wealth disparities have created a new deforestation problem; namely that poorer households now resort to stealing forest products. This acts as a disincentive for farmers to engage in agroforestry on the barren hillsides. Furthermore, women are being left out of the forest protection planning process and are losing decision-making authority both in their households and in their village. In conclusion, the case study demonstrates that without an equitable, inclusive land allocation process to prevent further poverty, land policy can have negative socioeconomic impacts. Forest protection cannot occur when people live in poverty; they cannot invest time and money into agroforestry, nor can they afford to protect the hillside crops and forest for the long-term gain unless their immediate food needs are met.

description: We identify 219 AdS$_4$ solutions in four-dimensional dyonically gauged ISO(7) $\mathcal{N}=8$ supergravity and present some of their properties. One of the new solutions preserves $\mathcal{N}=1$ supersymmetry and provides a rare explicit example of an AdS$_4$ vacuum dual to a 3d SCFT with no continuous global symmetry. There are also two new non-supersymmetric solutions for which all 70 scalar fields in the supergravity theory have masses above the BF bound. All of these AdS$_4$ solutions can be uplifted to massive type IIA supergravity. Motivated by this we present the low lying operator spectra of the dual 3d CFTs for all known supersymmetric AdS$_4$ solutions in the theory and organize them into superconformal multiplets.

description: Automatic visual fire detection is used to complement traditional fire detection sensor systems (smoke/heat). In this work, we investigate different Convolutional Neural Network (CNN) architectures and their variants for the nontemporal real-time bounds detection of fire pixel regions in video (or still) imagery. Two reduced complexity compact CNN architectures (NasNet-A-OnFire and ShuffleNetV2-OnFire) are proposed through experimental analysis to optimise the computational efficiency for this task. The results improve upon the current state-of-the-art solution for fire detection, achieving an accuracy of 95% for full-frame binary classification and 97% for superpixel localisation. We notably achieve a classification speed up by a factor of 2.3× for binary classification and 1.3× for superpixel localisation, with runtime of 40 fps and 18 fps respectively, outperforming prior work in the field presenting an efficient, robust and real-time solution for fire region detection. Subsequent implementation on low-powered devices (Nvidia Xavier-NX, achieving 49 fps for full-frame classification via ShuffleNetV2-OnFire) demonstrates our architectures are suitable for various real-world deployment applications. | Cited in: Efficient and Compact Convolutional Neural Network Architectures for Non-temporal Real-time Fire Detection (W.

description: A growing empirical literature is analyzing the effects of weather fluctuations on a variety of economic outcomes with the goal of better understanding the potential impacts of climate change. In agricultural studies, constructing weather variables typically requires researchers to define a “season”, a time period over which weather conditions are considered relevant to the agricultural outcome of interest. While researchers often have the background knowledge to make reasonable assumptions about seasonality in crop-specific analyses, these modeling choices are less obvious when dealing with aggregate agricultural data encompassing multiple crops or livestock. In this article, we explore the consequences of assuming an incorrect season in such analyses. We first provide a conceptual framework to show that imposing an incorrect season essentially introduces non-classical measurement error in weather regressors, causing unknown biases in weather impacts. We confirm this finding in simulations. We then propose a tractable data-driven approach to recover the “true” underlying season. The approach consists of a grid search with cross-validation that evaluates the fit of models based on a wide range of season definitions. In simulations, we find the approach is effective at recovering the “true” season under certain data generating processes. Finally, we apply our approach to a US state-level panel of agricultural Total Factor Productivity. We find, unsurprisingly, considerable differences in seasonality across regions. Importantly, our empirical findings suggest that imposing arbitrary seasons lead to substantially different estimates of weather effects in either direction, in line with our theoretical and simulated results. This work contributes to the development of more robust empirical studies of climate change impacts on agriculture and beyond.

description: In the same way that classical computer networks connect and enhance the capabilities of classical computers, quantum networks can combine the advantages of quantum information and communications. We propose a non-classical network element, a delayed commutation switch, that can solve the problem of switching time in packet switching networks. With the help of some local ancillary qubits and superdense codes we can route the information after part of it has left the network node.

Copula-Based Factor Model for Credit Risk Analysis

description: A standard quantitative method to access credit risk employs a factor model based on joint multivariate normal distribution properties. By extending a one-factor Gaussian copula model to make a more accurate default forecast, this paper proposes to incorporate a state-dependent recovery rate into the conditional factor loading, and model them by sharing a unique common factor. The common factor governs the default rate and recovery rate simultaneously and creates their association implicitly. In accordance with Basel III, this paper shows that the tendency of default is more governed by systematic risk rather than idiosyncratic risk during a hectic period. Among the models considered, the one with random factor loading and a state-dependent recovery rate turns out to be the most superior on the default prediction.

description: Metrichia corazones Armitage and Harris, new species
Fig. 7, 8
 Diagnosis. Metrichia corazones appears to be most closely related to M. helenae Flint and Bueno on the basis of the lack of abdominal pouches, the quadrate inferior appendages, and the pair of subapical phallic spines. It differs from this species in the inferior appendages being more rectanguloid, the phallic spines being dissimilar in length, and the phallus having a median process. The new species has enlarged, flattened antennae (Fig. 8H) and darkened foreleg tibia, with a row of stout setae (Fig. 8F).
 Description. Length 1.3–1.5 mm, 19 antennal segments, basal segments flattened and dilated, foreleg with tibia darkened and bearing row of stout setae, overall color brown (in alcohol).
 Male genitalia. Abdomen without eversable sacs, but with thick hair patches on segment VII and VIII, patches on VII much larger than those on VIII, with median sclerotized plate. Segment VII annular, with ventromesal process. Segment VIII triangular, narrowing anteroventrally. Segment IX truncate posteriorly, anteriorly narrowing ventrally; in dorsal view narrow posteriorly, anteriorly rounded. Preanal appendage (cercus) short and rectanguloid in lateral view; in dorsal view lobate; dorsolateral hook elongate and apically curving ventrad in lateral view; in dorsal view thick, with distal hook projecting laterally and serrate. Segment X elongate and narrow, in dorsal view thin and slightly tapering to notched apex, basally with membranous triangular lobe. Inferior appendages in lateral view rectanguloid, distally with posteroventral incision; in dorsal and ventral views wide basally, narrowing in distal ¼ length to acute apex. Phallus tubular, narrowing below mid-length where a lateral process originates, subapically with pair of spines, lowermost short, uppermost about twice length of lower and projecting posteriorly, apex with lateral sclerite.
 Female and larva. Unknown.

description: Samarium doped BiFeO3 compounds having nano-size crystallites were prepared by the ethylene glycol assisted sol-gel synthesis method. X-ray diffraction and SEM measurements as well as Raman spectroscopy and FTIR experiments were used to clarify the evolution of the crystal structure on microscopic and local scale levels in the compounds having formula Bi1-xSmxFeO3, where x equals from 0 to 1. Magnetization measurements along with the structural data were used to determine a correlation between magnetic properties and crystal structure of the compounds. The compounds with from x 0.1-0.2 are characterized by the sequence of the structural transitions driven by the dopant increase, from the polar rhombohedral phase to the non-polar orthorhombic phase via two-phase regions characterized by the presence of the anti-polar orthorhombic phase. The concentration regions ascribed to a coexistence of the rhombohedral and the anti-polar orthorhombic phases as well as theanti-polar orthorhombic and the non-polar orthorhombic phases are observed in the ranges from 0.12 to 0.15 and from 0.15 to 0.18 respectively. The compounds having single-phase rhombohedral structure are characterized by a release of remnant magnetization as compared to ceramics with similar chemical compositions but synthesized by the solid-state reaction method and having microscopic size crystallites. A correlation between the type of structural distortion, morphology of crystallites and an onset of remnant magnetization is discussed highlighting a difference in the evolution of crystal structure and magnetization observed for the Sm-doped ceramics prepared by modified sol-gel method and conventional solid-state reaction technique.

description: We carried out an unbiased survey for massive dense cores in the giant molecular cloud associated with eta Carinae with the NANTEN telescope in 12CO, 13CO, and C18O 1-0 emission lines. We identified 15 C18O cores. Two of the 15 cores are associated with IRAS point sources whose luminosities are larger than 10^4 Lo, which indicates that massive star formation is occuring within these cores. Five cores including the two with IRAS sources are associated with MSX point sources. We detected H13CO+ (1-0) emission toward 4 C18O cores, one of which is associated with neither IRAS nor MSX point sources. This core shows the presence of a bipolar molecular outflow in 12CO (2-1), which indicates that star formation is also occuring in the core. In total, six C18O cores out of 15 are experienced star formation, and at least 2 of 15 are massive-star forming cores in the eta Car GMC. We found that massive star formation occurs preferentially in cores with larger column density, mass, number density, and smaller ratio of virial mass to LTE mass Mvir/M. We also found that the cores in the eta Car GMC are characterized by large line width and Mvir/M on average compared to the cores in other GMCs. We investigated the origin of a large amount of turbulence in the eta Car GMC. We propose the possibility that the large turbulence was pre-existing when the GMC was formed, and is now dissipating. Mechanisms such as multiple supernova explosions in the Carina flare supershell may have contributed to form a GMC with a large amount of turbulence.
