Serrata amphora

description: Serrata amphora n. sp. Fig. 32 TYPE MATERIAL. — Holotype (dd) MNHN 20612. TYPE LOCALITY. — Southern New Caledonia, 23°09’S, 167°11’E, 650-680 m [BIOCAL: stn DW 36]. MATERIAL EXAMINED. — Southern New Caledonia. BIOCAL: stn DW 36, 23°09’S, 167°11’E, 650-680 m, 1 dd (holotype, Fig. 32). DISTRIBUTION. — Southern New Caledonia, one shell in 650-680 m. DESCRIPTION. — Shell ovate subcylindrical, slender, solid, opaque. Protoconch paucispiral, small, slightly bulging, smooth. Spire moderate-sized, conical, whorls faintly convex. Aperture narrow, very oblique, widening weakly anteriorly and attenuated towards base. Base tapering. Outer lip thin, regular, subvertical. Shoulder sloping weakly, outer edge making an angle below shoulder, very weakly arched over its anterior two thirds, outer margin wide, thickened, rounded, not stepped, inner edge weakly oblique, bearing 18 medium-sized, subequal denticles, similar in size to the interspaces. Four thin columellar plaits, 2 anterior ones oblique, slightly sinuous, 2 posterior ones less oblique, decreasing in size posteriorly. Ground colour whitish (faded), with faint wide pale orange markings on upper half and on base of outer margin. Dimensions: 8.70 x 4.10 mm. Radula unknown. REMARKS. — Despite its larger size, the shell morphology of Serrata amphora is intermediate between S. hians and S. dentata in general outline, its columellar plaits are similar to those of these 2 species, and its labial denticles are similar to those of S. aureosa. S. amphora differs from S. hians in its more slender shell and its subpyriform outline, its much narrower aperture and its more numerous and regular labial denticles. It differs from S. aureosa in its larger and more slender shell, its thinner and more oblique columellar plaits, its less reflected outer lip and its slightly narrower aperture. It differs from S. dentata in its larger shell and its subpyriform outline, its slightly narrower aperture, its more numerous and less spaced labial denticles. Serrata hians, S. dentata and S. aureosa occur in close proximity to S. amphora, but without any intergrading of shell morphology. ETYMOLOGY. — Latin amphora (n., amphora), referring to the general outline of the shell, which suggests the classical shape of the antique amphora.

description: We develop the embedding formalism for conformal field theories, aimed at doing computations with symmetric traceless operators of arbitrary spin. We use an index-free notation where tensors are encoded by polynomials in auxiliary polarization vectors. The efficiency of the formalism is demonstrated by computing the tensor structures allowed in n-point conformal correlation functions of tensors operators. Constraints due to tensor conservation also take a simple form in this formalism. Finally, we obtain a perfect match between the number of independent tensor structures of conformal correlators in d dimensions and the number of independent structures in scattering amplitudes of spinning particles in (d+1)-dimensional Minkowski space.

description: We construct all SU_L(3)*SU_R(3) chirally invariant anomalous magnetic, i.e. involving a Pauli tensor and one-derivative, interactions of one chiral-[(8,1)+(1,8)] meson field with chiral-[(6,3)+(3,6)], [(3,\bar3)+(\bar3,3)], and [(8,1)+(1,8)] baryon fields and their "mirror" images. We find strong chiral selection rules: e.g. there is only one off-diagonal chirally symmetric anomalous magnetic interaction between J=1/2 fields belonging to the [(6,3)+(3,6)] and the [(3,\bar3)+(\bar3,3)] chiral multiplets. We also study the chiral selection rules for the anomalous magnetic interactions of the [(3,\bar3)+(\bar3,3)] and the [(8,1)+(1,8)] baryon fields. Again, no diagonal and only one off-diagonal chiral SU_L(3)*SU_R(3) interaction of this type is allowed, that turns out also to conserve the U_A(1) symmetry. We calculate the F/D ratios for the baryons' anomalous magnetic moments predicted by these interactions in the SU(3) symmetry limit and find that only the [(6,3)+(3,6)]-[(3,\bar3)+(\bar3,3)] one, reproduces F/D=1/3, in close proximity to the value extracted from experiment.

Priors on the Variance in Sparse Bayesian Learning; the demi-Bayesian Lasso
Creators: name: Madigan, David
Publisher: name: Columbia University
Year: 2008
Subjects: subject: Statistics
subject: FOS: Mathematics

description: We explore the use of proper priors for variance parameters of certain sparse Bayesian regression models. This leads to a connection between sparse Bayesian learning (SBL) models (Tipping, 2001) and the recently proposed Bayesian Lasso (Park and Casella, 2008). We outline simple modifications of existing algorithms to solve this new variant which essentially uses type-II maximum likelihood to fit the Bayesian Lasso model. We also propose an Elastic-net (Zou and Hastie, 2005) heuristic to help with modeling correlated inputs. Experimental results show the proposals to compare favorably to both the Lasso and traditional and more recent sparse Bayesian algorithms.

description: We perform a complete one-loop calculation of meson-meson scattering, and of the scalar and pseudoscalar form factors in U(3) chiral perturbation theory with the inclusion of explicit resonance fields. This effective field theory takes into account the low-energy effects of the QCD U_A(1) anomaly explicitly in the dynamics. The calculations are supplied by non-perturbative unitarization techniques that provide the final results for the meson-meson scattering partial waves and the scalar form factors considered. We present thorough analyses on the scattering data, resonance spectroscopy, spectral functions, Weinberg-like sum rules and semi-local duality. The last two requirements establish relations between the scalar spectrum with the pseudoscalar and vector ones, respectively. The Nc extrapolation of the various quantities is studied as well. The fulfillment of all these non-trivial aspects of the QCD dynamics by our results gives a strong support to the emerging picture for the scalar dynamics and its related spectrum.

description: The holographic $Λ(t)$CDM model in a non-flat universe is studied in this paper. In this model, to keep the form of the stress-energy of the vacuum required by general covariance, the holographic vacuum is enforced to exchange energy with dark matter. It is demonstrated that for the holographic model the best choice for the IR cutoff of the effective quantum field theory is the event horizon size of the universe. We derive the evolution equations of the holographic $Λ(t)$CDM model in a non-flat universe. We constrain the model by using the current observational data, including the 557 Union2 type Ia supernovae data, the cosmic microwave background anisotropy data from the 7-yr WMAP, and the baryon acoustic oscillation data from the SDSS. Our fit results show that the holographic $Λ(t)$CDM model tends to favor a spatially closed universe (the best-fit value of $Ω_{k0}$ is -0.042), and the 95% confidence level range for the spatial curvature is $-0.101

description: We study the perturbative evolution of the static configurations, quasinormal modes and quasi normal ringing in the Apostolatos - Thorne cylindrical shell model. We consider first an expansion in harmonic modes and show that it provides a complete solution for the characteristic value problem for the finite perturbations of a static configuration. As a consequence of this completeness we obtain a proof of the stability of static solutions under this type of perturbations. The explicit expression for the mode expansion are then used to obtain numerical values for some of the quasi normal mode complex frequencies. Some examples involving the numerical evaluation of the integral mode expansions are described and analyzed, and the quasi normal ringing displayed by the solutions is found to be in agreement with quasi normal modes found previously. Going back to the full relativistic equations of motion we find their general linear form by expanding to first order about a static solution. We then show that the resulting set of coupled ordinary and partial differential equations for the dynamical variables of the system can be used to set an initial plus boundary values problem, and prove that there is an associated positive definite constant of the motion that puts absolute bounds on the dynamic variables of the system, establishing the stability of the motion of the shell under arbitrary, finite perturbations. We also show that the problem can be solved numerically, and provide some explicit examples that display the complete agreement between the purely numerical evolution and that obtained using the mode expansion, in particular regarding the quasi normal ringing that results in the evolution of the system. We also discuss the relation of the present work to some recent results on the same model that have appeared in the literature.

MATERIAL EXAMINED. — Norfolk Ridge. BERYX 11: stn DW 09, 24°52’S, 168°22’E, 635-680 m, 1 dd (holotype, Fig.34). DISTRIBUTION. — Northern Norfolk Ridge, one shell in 635-680 m. DESCRIPTION. — Shell ovate fusiform, thin, subtranslucent. Protoconch paucispiral, wide, dome-shaped, smooth. Spire moderate-sized, triangular, blunt, whorls weakly convex. Aperture wide, very oblique, widening slightly towards base, nearly parallel-sided. Base faintly tapering. Outer lip thin, weakly arched, subvertical, shoulder sloping, faintly angled at contact with last whorl, rounded, outer margin narrow, rounded, stepped, inner edge smooth. Four thin columellar plaits, very oblique, lower one long, subvertical, weakly angled over anterior part, 3 upper ones decreasing in size posteriorly. Colour whitish (faded). Dimensions: 5.10 x 2.20 mm. Radula unknown. REMARKS. — The shell morphology of Serrata laevis is very similar to that of S. perlucida, principally in the hyaline and juvenile appearance of the shell, the rather tall, massive spire with convex whorls, the wide aperture with a thin, smooth labrum, the narrow, rounded, stepped outer margin, and the thin, oblique, columellar plaits arranged in a fan-like pattern, with the lowest one weakly angled and subvertical. As in S. perlucida, the outer margin is stepped and well-marked. Serrata laevis differs from S. perlucida principally in its thicker shell, its less inflated shell outline, its less widened aperture and its less thin and sharp outer lip. The single shell was found at a shallower depth and further south than the 4 specimens of S. perlucida. ETYMOLOGY. — Latin laevis (adj., light, not heavy), referring to the fragile consistency of the shell.

Thermomechanical milling of lithics in volcanic conduits
Creators: name: Campbell, Michelle
Publisher: name: University of British Columbia
Year: 2012

description: Pyroclastic deposits resulting from explosive volcanic eruptions commonly contain clasts originating from the conduit wall rocks, which were entrained into the rapidly ascending stream of erupting material. These particles are termed accessory lithic clasts. Previous studies of the relative abundances and compositions of accessory lithic clasts have been used to identify the subsurface wall rocks of the volcanic conduit, to document variations in eruptive intensity, or to track changes in conduit or vent geometry over the course of the eruption. However, the morphological properties of accessory lithic clasts are largely ignored and offer an unused means of studying the processes operating in the conduit during explosive eruptions. During a volcanic eruption, wall rocks are violently fragmented to produce clasts that are incorporated into a hot, high velocity, particle-laden gas jet. There the clasts are subjected to elevated temperatures, blasting by volcanic ash, and occasional collisions with other large particles or with the conduit walls. The resultant morphologies of the accessory lithic clasts will be influenced by 1) the intrinsic physical properties of the clasts in question; 2) the specific physical and thermal processes to which the clasts were subjected within the conduit; and 3) the residence times of the clasts within the conduit. The 2360 B.P. Pebble Creek Formation of the Mount Meager Volcanic Complex in SW British Columbia is the product of the most recent explosive eruption in Canada. This formation includes a widespread pumice fallout deposit containing anomalously rounded and smoothed monzogranite accessory lithic clasts. In this study, I seek to explain the unusual shapes and surface textures of these clasts through detailed field work, analysis of sample morphology, and the computation of likely conditions within the conduit. My aim is to produce a comprehensive, mechanistic model of how these lithic clasts were reshaped within the volcanic conduit.

description:
In many southern Mediterranean mountain areas, the livelihoods of subsistence farmers are threatened by increasing drought periods that affect agroecosystems and cause rapid socioeconomic deterioration. Current initiatives to address this through ecosystem restoration often overlook the cultural significance of different tree species that play an important role in farmers' livelihoods. This may result in the erosion of biocultural diversity and loss of local and Indigenous knowledge. We used the cultural keystone species (CKS) framework to appraise the cultural and livelihood importance of 5 farm tree species—almond, ash, holm oak, olive, and walnut—in Morocco's central High Atlas mountains. Twenty-five structured interviews with knowledgeable farmers revealed that olive trees remain central to local residents' culture. This species met all CKS criteria, whereas walnut and almond trees met many criteria, but they have increasingly lost their cultural importance. Ash and holm oak are prevalent fodder species but do not directly bolster household cash incomes, and they are absent from cultural narratives, ceremonies, and symbolism. Our findings emphasize the importance of considering farm trees' cultural status in developing a culturally sensitive approach to conservation, stewardship of existing trees, and sustainable development in the Mediterranean mountains.

Silent films

description: Research thus far has only illuminated one Colombian silent film made by a woman. She was not a native Colombian, but a self-taught anthropologist born in the United States. The travelogue, made by Kathleen Romoli, was independently produced ten years after the end of the silent film era in the United States. Brought to light by the Fundación Patrimonio Fílmico Colombiano, it is significant because of its subject matter. The mining company Gold Platinum (GP) requested a promotional film about its operations in the Colombian Pacific coast. Romoli, a prominent historian and anthropologist, shot A Journey to the Operations of the South American Gold Platinum Co. (1937), also known as Gold Platinum (1937), paying special attention to the Embera community, which was in contact with the dredge camps in the 1930s. She never mentioned Gold Platinum to her family or colleagues. The film, which depicts the area where Romoli lived in Colombia and portrays the indigenous groups that Romoli wrote about, was found in her library after her death. In the 1990s, Patrimonio Fotográfico y Fílmico del Valle del Cauca, a Colombian regional institution under the Ministry of Culture, ran a preservation campaign in the Chocó region (Vidal 2011; Torres and Moreno 2009, n.p.). People living in “La Esmeralda,” Romoli’s estate in Trujillo, gave them twenty cans of 16mm film. These included Gold Platinum, left over material from the travelogue, and other footage from a later time. Circumstantial evidence suggests that Romoli was the author of Gold Platinum.

description: We discuss a novel dark matter signature relevant for directional detection of Weakly Interacting Massive Particles (WIMPs). For heavy enough WIMPs and low enough recoil energies, the maximum of the recoil rate is not in the direction of the average WIMP arrival direction but in a ring around it at an angular radius that increases with the WIMP mass and can approach 90 degrees at very low energies. The ring is easier to detect for smaller WIMP velocity dispersion and larger average WIMP velocities relative to the detector. In principle the ring could be used as an additional indication of the WIMP mass range.

DESCRIPTION. — Shell ovate fusiform, thin, opaque. Protoconch paucispiral, medium-sized, bulging, eroded. Spire medium-sized, conical, whorls flat. Aperture moderately wide, very oblique, widening slightly towards base. Base slightly tapering. Outer lip very thin, very oblique, weakly arched, shoulder sloping at very low angle, outer margin slightly thickened, moderately wide, sharply bevelled, inner edge sharp, smooth. Four very thin columellar plaits, lowest one long, very oblique, faintly angled anteriorly, 3 upper ones much less oblique, decreasing regularly in size posteriorly, fourth plait nearly horizontal. Colour brownish (stained). Dimensions: 6.65 x 3.20 mm. Radula unknown. REMARKS. — Serrata carinata was found syntopically with S. laevis. It seems to form an intergrade between S. laevis and the following species. Serrata carinata matches S. laevis more closely because of its noticeably widened aperture and its truncated base. It differs from S. laevis mainly in its less inflated outline, its more attenuated spire, its slightly less widened aperture, the sharper inner border of its labrum and the carinate appearance of its outer margin. Serrata laevis itself links S. carinata and S. perlucida. Serrata carinata also appears to match the shell morphology of S. hians closely, differing principally from this species in its smaller size, its lighter shell with a thinner labrum, its less oblique columellar plaits and the more widening upper part of its aperture. ETYMOLOGY. — Latin carina (n., convex base of a ship’s hull, the keel) and –ta (adjective suffix), referring to the angled section of the outer margin of the shell.

Behavior-Profile Clustering For False Alert Reduction in Anomaly Detection Sensors
Creators: name: Frias-Martinez, Vanessa
Publisher: name: Columbia University
Year: 2009
Subjects: Computer science

description: Anomaly Detection (AD) sensors compute behavior profiles to recognize malicious or anomalous activities. The behavior of a host is checked continuously by the AD sensor and an alert is raised when the behavior deviates from its behavior profile. Unfortunately, the majority of AD sensors suffer from high volumes of false alerts either maliciously crafted by the host or originating from insufficient training of the sensor. We present a cluster-based AD sensor that relies on clusters of behavior profiles to identify anomalous behavior. The behavior of a host raises an alert only when a group of host profiles with similar behavior (cluster of behavior profiles) detect the anomaly, rather than just relying on the host's own behavior profile to raise the alert (single-profile AD sensor). A cluster-based AD sensor significantly decreases the volume of false alerts by providing a more robust model of normal behavior based on clusters of behavior profiles. Additionally, we introduce an architecture designed for the deployment of cluster-based AD sensors. The behavior profile of each network host is computed by its closest switch that is also responsible for performing the anomaly detection for each of the hosts in its subnet. By placing the AD sensors at the switch, we eliminate the possibility of hosts crafting malicious alerts. Our experimental results based on wireless behavior profiles from users in the CRAWDAD dataset show that the volume of false alerts generated by cluster-based AD sensors is reduced by at least 50% compared to single-profile AD sensors.

description: Given a rational $a=p/q$ and $N$ nonnegative $d$-dimensional real vectors $u_1$, ..., $u_N$, we show that it is always possible to choose $(d-1)+\lceil (pN-d+1)/q\rceil$ of them such that their sum is (componentwise) at least $(p/q)(u_1+...+u_N)$. For fixed $d$ and $a$, this bound is sharp if $N$ is large enough. The method of the proof uses Carathéodory's theorem from linear programming.

We justify the mean-field approximation and offer a rigorous derivation of the 3D cubic NLS with a quadratic trap. We establish the space-time bound conjectured by Klainerman and Machedon [30] for β in (0,2/7] by adapting and simplifying an argument in Chen and Pavlović [7] which solves the problem for β in (0,1/4) in the absence of a trap.

description: The rapid growth of the hedge fund industry has attracted increasing attention from government regulators. In the United States, for example, the Securities and Exchange Commission(SEC) voted in October 2004 to require many hedge funds to officially register with the Commission beginning in 2006. Actions such as this have led to a widening debate over whether(or to what extent) government should play a role in the development of the hedge fund industry. To address this issue, The Program on Alternative Investments at Columbia Business School's Center on Japanese Economy and Business sponsored a symposium entitled "Should Hedge Funds Be Regulated?" which was held at New York's University Club in November 2004. U.S. SEC Commissioner Harvey Goldschmid, currently on leave from Columbia Law School, delivered the keynote speech, arguing in favor of the Commission's October decision. Following Commissioner Goldschmid's address, Program Director Mark Mason moderated a panel of leading experts from the business, government, and academic communities who debated the pros and cons of government involvement in the industry.

description: Eslanda Cardozo Goode Robeson had a varied and remarkable career both within and outside motion picture filmmaking, working initially as the first Black hired at New York City’s Presbyterian Hospital in the surgical pathology department. After her marriage to Paul Robeson, world-renowned actor, singer, and activist, whose biography she wrote in 1930, she joined him in several independent film projects. Later she worked as an anthropologist and travel writer. In addition to being Robeson’s talent manager when he worked on Body and Soul (1925), Charles Musser argues that Eslanda managed many aspects of her husband’s film career as well his musical and theatrical career (91). In the silent era, Eslanda appears only in the avant-garde classic Borderline (1930), but later would have a role, which she negotiated to secure, as a café proprietress in the Robeson film Big Fella (1937) (Duberman 207).

description: The effective Lagrangian for η' incorporating the effect of the QCD θ-angle has been developed previously. We revisit this Lagrangian and carry out its canonical quantization with particular attention to the test function spaces of constraints and the topology of the η'-field. In this way, we discover a new chirally symmetric coupling of this field to chiral multiplets which involves in particular fermions. This coupling violates P and T symmetries. In a subsequent paper, we will evaluate its contribution to the electric dipole moment (EDM) of fermions. Our motivation is to test whether the use of mixed states restores P and T invariance, so that EDM vanishes. This calculation will be shown to have striking new physical consequences.

description: Details about the life of Rosario Rodríguez de la Serna are scarce. We know only that she played a small acting role in Juro no volver a amar/I Swear I Won’t Love Again (1925). After this experience, she founded her own film company, Rosario Film, in order to direct Malditas sean las mujeres/Damned Be the Women (1925), a loose adaptation of a novel by Ibo Alfaro. In the film, a young boy, a victim of passion, falls into despair because of unrequited love and ends up killing himself. The film had limited commercial success and was exhibited at several locations in the country.
Planning Theory and Techniques

Subjects: Economics

description: The formulation of the successive Five-Year Plans in India has led to a steady evolution of economic thinking on questions relating to planning theory and techniques. However, the interplay between plans and economic thinking has often been tenuous. At times there may even have been post-facto rationalization of investment decisions taken on political grounds by ingenious designing of suitable models. At other times, model building and analysis have inevitably gone ahead of the plans. However, it is possible to identify with each plan certain basic model-types, which have provided the intellectual backbone to that plan and were the object of extensive economic debate. It is indeed surprising that while the true cost of labor came in for a good deal of discussion, the associated concept of the true cost of capital did not figure much in the Indian discussion. It was, of course, mentioned from time to time that the market rate of interest did not reflect the true scarcity of capital but it was not quite clear what was meant by such an expression.
Beta-detected NMR of ⁸Li⁺ in spintronic materials

Publisher: name: University of British Columbia

description: β-detected Nuclear Magnetic Resonance (βNMR) employs radioactive ⁸Li⁺ , which is optically spin-polarized, as a local probe to study magnetism in materials via β decay. In this thesis, βNMR is applied to spintronic materials, including GaAs, Ga₁₋xMnx Asand Fe/GaAs heterostructures in a depth-controlled manner at TRIUMF. High resolution β-NMR measurements were carried out on GaAs crystals (semi-insulating (SI-GaAs) and heavily doped n-type (n-GaAs)) as a control experiment for β-NMR on Fe/GaAs heterostructures. A small resonance shift was observed and found to be dependent on depth, temperature and doping. The depth dependence is only observed in SI-GaAs and not in n-GaAs. The resonance shift below 150 K in both GaAs is ∼ 100 ppm, on the same order of some Knight shifts of ⁸Li⁺ in noble metals. Ga₁₋xMnxAs is the first βNMR study on a ferromagnetic material through the ferromagnetic transition. Both spin lattice relaxation (SLR) and resonance of ⁸Li⁺ were measured. Two resonances were clearly resolved from the nonmagnetic GaAs substrate and the magnetic Ga₁₋xMnxAs film. The latter one negatively shifts and is linearly proportional to the applied field. The hyperfine coupling constant AHF of ⁸Li⁺ in Ga₁₋xMnxAs is found to be negative. The SLR rate λ does not follow Korringa’s Law and its amplitude shows a weak temperature dependence through TC. The behaviours of AHF and λ suggest that the delocalized holes originate from a Mn derived impurity band. No evidence of magnetic phase separation is found. ⁸Li⁺ provides a new depth-dependent local probe to detect injected spin polarization. We measured the ⁸Li⁺ resonance in Fe/GaAs heterostructures with semi-insulating and heavily doped n-type substrates, with and without injected current. With zero current, no spin polarization at thermal equilibrium is found. A new current injection system was designed and setup to conduct current injection from the thin Fe layer into the n-GaAs substrate. We found effects of local Joule heating and a very small stray field caused by the injected current but no convincing evidence of injected spin polarization.

description: We examine how the properties of the Kondo insulators change when the symmetry of the underlying crystal field multiplets is taken into account. We employ the Anderson lattice model and consider its low-energy physics. We show that in a large class of crystal field configurations, Kondo insulators can develop a topological non-trivial ground-state. Such topological Kondo insulators are adiabatically connected to non-interacting insulators with unphysically large spin-orbit coupling, and as such may be regarded as interaction-driven topological insulators. We analyze the entanglement entropy of the Anderson lattice model of Kondo insulators by evaluating its entanglement spectrum. Our results for the entanglement spectrum are consistent with the surface state calculations. Lastly, we discuss the construction of the maximally localized Wannier wave functions for generic Kondo insulators.

description: Best known as the wife and collaborator of Alfred Hitchcock, Alma Reville’s career as a screenwriter and editor has largely been overshadowed by that of her director husband. As Hitchcock was fond of pointing out, however, Reville entered the film industry long before he did and by the time they met in 1921, she was already an experienced editor, continuity supervisor, and director’s assistant (1995, 51). Around 1915, at the age of sixteen, Reville joined the London Film Company which was based near her family home in Twickenham. Starting out as a tea girl, she was soon promoted to the cutting room and within two years was working as an assistant to director Maurice Elvey, according to a 1925 article in The Picturegoer (48). In 1918, she took a role in Elvey’s The Life Story of David Lloyd George (Hitchcock O’Connell and Bouzereau 2003, 26-27). This experience may have briefly inspired her with the desire to become an actress but despite a fleeting cameo in The Lodger (1927), the remainder of her career was based behind, rather than in front of, the camera.

description: Best known as Jean Renoir’s film editor and life partner during the 1930s, the career of Marguerite Renoir (née Houllé) before (and after) their collaboration has been largely overlooked, partly due to the scarcity of extant archival materials. Marguerite’s career began at the Pathé Studios of Joinville-le-Pont, where she worked as an apprentice-colorist starting around 1921 (Bertin 1991, 70). Although the Pathé Archives hold no records of Renoir’s early film career, her personal testimony in the professional journal Le Technicien du Film indicates that she became an editor that same year (“L’Actualité” 1960, 4-5). She met famed director Jean Renoir in 1927, while she was working as the editor of Alberto Cavalcanti’s La P’tite Lili (1929), which featured Jean in an uncredited performance and his first wife, Catherine Hessling, in the starring role. Marguerite and Jean’s first collaboration occurred in 1929, when Marguerite edited Jean’s seventh and last silent feature, Le Bled, and the two became romantically involved. Although they never married, Marguerite used Renoir as her name and retained it throughout her career. She is sometimes referred to as Marguerite Houllé-Renoir or Marguerite Mathieu, Mathieu being the name of her husband, the singer Adolphe Mathieu, whom she shot in self-defense in 1948 (“Bagarre sur le palier” 1948, n.p.). After one month in prison, Marguerite was released and continued working as an editor for many celebrated filmmakers (e.g., Jacques Becker, Luis Buñuel, and Jean-Pierre Mocky) until the early 1970s.

description: Recent measurement of the $γγ^\ast$ form factor of the neutral pion in the high $Q^2$ region disagrees with {\em a priori} predictions of QCD-based calculations. We comment on existing explanations, and analyze a possibility that this discrepancy is not due to poorly understood QCD effects, but is a result of some new physics beyond the standard model (SM). We show that such physics would necessarily involve a new neutral light state with mass close to the mass of $π^0$, and with stronger than $π^0$ couplings to heavier SM flavors such as $c$, $τ$, and $b$. It is found that only the coupling to the $τ$ lepton can survive the existing constraints and lead to the observed rise of the pion form factor relative to $Q^{-2}$ at high $Q^2$. We perform numerical fits to data and determine the allowed range of masses and couplings for such new particles. This range of masses and couplings could also reduce or eliminate the tension between the $e^+e^-$ and $τ$ decay determinations of the hadronic vacuum polarization. Dedicated experimental analysis of $τ$ pair production in association with such new states should provide a conclusive test of the new physics hypothesis as an explanation to the pion form factor rise. We also comment on the calculations of the pion form factor in the chiral quark model, and point out a possible dynamical origin of the quark mass scale inferred from the form factor measurement.

description: The detection of high energy (HE) γ-ray emission up to about 3 GeV from the giant lobes of the radio galaxy Centaurus A has been recently reported by the Fermi-LAT Collaboration based on ten months of all-sky survey observations. A data set more than three times larger is used here to study the morphology and photon spectrum of the lobes with higher statistics. The larger data set results in the detection of HE γ-ray emission (up to about 6 GeV) from the lobes with a significance of more than 10 and 20 σ for the North and the South lobe, respectively. Based on a detailed spatial analysis and comparison with the associated radio lobes, we report evidence for a substantial extension of the HE γ-ray emission beyond the WMAP radio image in the case of the Northern lobe of Cen A. We reconstruct the spectral energy distribution (SED) of the lobes using radio (WMAP) and Fermi-LAT data from the same integration region. The implications are discussed in the context of hadronic and leptonic scenarios.

description: In Ashtekar's Hamiltonian formulation of general relativity, and in loop quantum gravity, Lorentz covariance is a subtle issue that has been strongly debated. Maintaining manifest Lorentz covariance seems to require introducing either complex-valued fields, presenting a significant obstacle to quantization, or additional (usually second class) constraints whose solution renders the resulting phase space variables harder to interpret in a spacetime picture. After reviewing the sources of difficulty, we present a Lorentz covariant, real formulation in which second class constraints never arise. Rather than a foliation of spacetime, we use a gauge field y, interpreted as a field of observers, to break the SO(3,1) symmetry down to a subgroup SO(3)_y. This symmetry breaking plays a role analogous to that in MacDowell-Mansouri gravity, which is based on Cartan geometry, leading us to a picture of gravity as 'Cartan geometrodynamics.' We study both Lorentz gauge transformations and transformations of the observer field to show that the apparent breaking of SO(3,1) to SO(3) is not in conflict with Lorentz covariance.
