Wang Meng and Self-censorship
Creators: name: Larson, Wendy
Publisher: name: The Journal of the European Association for Chinese Studies
Year: 2021

description: The early work and experience of writer (and later Minister of Culture) Wang Meng provides a useful study in the “slow creep” of active, optimistic efforts on behalf of both political authorities and the people to create a unified cultural subject, as they move toward a more recognisable form of censorship and control. Although parts of Wang Meng’s first novel Long live youth were published in the late 1950s, it was not published in its entirety until 1979. The plot revolves around a group of high school girls who value spontaneity and freedom, rather than discipline and organisation. The small group of main characters develop strategies of inclusion and exclusion, mimicking society at large while shielding themselves from the contamination of politics and national affairs. By the time he wrote the novella A Young Man Arrives at the Organization Department in 1956, Wang Meng had reformulated his protagonist to recognise the insidious danger of self-censorship. Lin Zhen retains the values of “good cheer” and hard work but falls into doubt and confusion. The story’s portrayal of Lin’s colleagues in the Organization Department as lazy, cautious, and unenthusiastic is also part of a literary investigation into the kind of censorship that is woven into daily work life, emerging from the structures of bureaucracy. 上世紀50年代曾任文化部長的王蒙寫的兩部小說《青春萬歲》和《組織部新來的年輕人》呈現了中國50年代積極向上的樂觀主義精神。 《青春萬歲》寫的是一群追崇自由，隨性爛漫，不喜被組織和紀律約束的高中女生。她們對他人包容和排斥的策略，既是當時社會制度和風氣的體現，又展示了年輕人未經政治風雨及世俗侵染的青春和純潔。 《組織部新來的年輕人》揭露了官僚機構中逐漸滲透到日常工作中的審查制度。王蒙塑造了一個能自我審查隱患的主角林震。雖然其組織部的同事在小說中被描述為懶惰、謹慎並缺乏熱忱，林震自己也時常陷入懷疑和困惑，但他保留了“打起精神”和努力工作的價值觀。通過研究王蒙這兩部小說中所展現出來的樂觀主義精神，本文揭示了那個時代的當權者和民眾是如何將這種樂觀向上的價值取向逐步演變成政治審查的要素，從而構建起一個統一的文化主題。

Screening without China

description: How can research into film policy inform us about the nature of power and cultural politics regarding film censorship? How does censorship affect the aesthetics and identity of film-making produced under political and market constraints? Focusing on the geopolitical regions of British Hong Kong, Taiwan, and China, this article delineates the impact of British colonial film censorship and the politics of cinematically representing revolutionary China during the Cold War. It reveals that British Hong Kong censors changed their strategy in the 1970s and 80s from suppressing mainland Chinese films to inhibiting films that might offend China from screening in Hong Kong. The evidence points to a distinctive picture of transregional smuggling and cinematic boundary-crossing, namely, the dangerous trafficking and interception of movie images, ideologies, and propaganda. Film screening of ‘China’ in Hong Kong and Taiwan was subject to strict official surveillance to quarantine undesirable public visuality and political discourses. The study examines film’s ambiguous expressions of China and Chineseness as it constantly negotiated the factors of colonialism, Chinese nationalism, and Cold War transnational politics. 電影政策的研究如何揭示電影審查的權力機制及其文化政治的本質？在政治和市場的約束下，審查制度又如何影響電影製作的美學和自我定位？本文將聚焦英殖香港、台灣和中國這三個地緣政治區域，探討英國在殖民地實行的電影審查制度的影響，以及冷戰時期電影革命對中國政治的指涉。 1970至80年代期間，英殖香港的電影審查員改變了以往審查策略，從打壓中國大陸的電影變成禁止在香港放映可能會冒犯中國的電影。從這種策略上的改變可以看出跨地域“走私”音像影視對意識形態和宣傳領域的獨特影響。在當時的香港和台灣，放映和觀看有關「中國」的電影受到官方的嚴格監控，以杜絶可能惹是生非的公眾現象和政治話語。本文將呈現冷戰時期的港台電影及其在中國和中國性這兩個概念上模棱兩可的表達，研究在這種視覺記錄中，人們面對和處理殖民主義、中國民族主義和冷戰跨國政治等問題的過程。

description: Atom optics demonstrates optical phenomena with coherent matter waves, providing a foundational connection between light and matter. Significant advances in optics have followed the realisation of structured light fields hosting complex singularities and topologically non-trivial characteristics. However, analogous studies are still in their infancy in the field of atom optics. Here, we investigate and experimentally create knotted quantum wavefunctions in spinor Bose--Einstein condensates which display non-trivial topologies. In our work we construct coordinated orbital and spin rotations of the atomic wavefunction, engineering a variety of discrete symmetries in the combined spin and orbital degrees of freedom. The structured wavefunctions that we create map to the surface of a torus to form torus knots, Möbius strips, and a twice-linked Solomon's knot. In this paper we demonstrate striking connections between the symmetries and underlying topologies of multicomponent atomic systems and of vector optical fields--a realization of topological atom-optics.

More than Conformity or Resistance

Publisher: name: The Journal of the European Association for Chinese Studies
Year: 2021

description: One of the most popular literary and cultural practices particularly in the digital age, “boys’ love” (BL, danmei 耽美) manga and fictional works are fantasies on romantic or homoerotic male-male relationships, and therefore are often naturally associated with homosexuality and pornography, two “morally” suspicious targets of government censorship in the heteronormative Chinese culture. This article aims to examine the various, indeed often opposite, strategies and tactics taken by BL participants and by some conscientious netizens on popular social media to illustrate how those who are under the threat of censorship grapple with harsh reality. In this article I argue that the BL practitioners’ responses to Chinese government’s anti-pornography campaigns are not simply a passive or reluctant “reaction.” I will first study the web adaptation of Priest’s BL story Zhenhun, demonstrating Priest’s as well as her fans’ tactful collaboration with the consumer culture and willing conformity to official discourse. Forming a sharp contrast with Priest’s commercial success, the controversial ten-year jail sentence of another BL writer, Gouwazi Tianyi, for profiting from producing and selling BL fiction has caused widespread outcry from both BL fans and ordinary netizens on Chinese social media. This case not only questions the dated criminal laws on obscene articles, but also challenges the patriarchal and problematic social institutions. 作為數字時代最受歡迎的流行文學和文化實踐，耽美漫畫和虛構作品是對男男浪漫的戀愛關係或性關係的想像，因此常與同性戀和色情聯繫起來。而在以異性戀為正統的中國文化中，常常成為政府審查制度針對的“道德”目標。本文旨在研究耽美參與者和一些有良知的網民在社交媒體上採取的不同甚至相反的策略，以展現人們如何應對嚴酷審查的現實。本文通過研讀網絡耽美劇《鎮魂》的接受情況解讀了耽美作家Priest及其粉絲與消費文化和官方話語的共謀。同時通過探討耽美作家狗娃子天一因寫作和銷售耽美小說而被判刑的案例，展示了耽美參與者和網民對陳舊法律的質疑，以及對父權制的社會制度的挑戰。

description: In the first part of this article, I briefly review early research activities concerning strongly correlated electron systems, beginning with the discovery of superconductivity and the first observation of a resistance minimum in nominally pure Cu-metal, which was explained many years later by Kondo. I will also address the antagonistic behavior of conventional (BCS) superconductivity and magnetism. The main focus of this paper is on the discovery of non-BCS-type superconductivity in the Kondo-lattice system CeCu$_2$Si$_2$, a prototypical heavy-fermion metal. Here, the superconducting state is created by a periodic lattice of 100% of magnetic Ce^3+ ions. Meanwhile, more than fifty lanthanide-, actinide-, and transition-metal-based intermetallic compounds are known to belong to the class of heavy-fermion superconductors. Finally, I will give my personal view of the current knowledge of this kind of unconventional superconductivity.

Numerical Study of Spin Hall Transport in a Two Dimensional Hole Gas System

description: We present a numerical study of the spin Hall effect in a two-dimensional hole gas (2DHG) system in the presence of disorder. We find that the spin Hall conductance (SHC), extrapolated to the thermodynamic limit, remains finite in a wide range of disorder strengths for a closed system on torus. But there is no intrinsic spin Hall accumulation as induced by an external electric field once the disorder is turned on. The latter is examined by performing a Laughlin's Gedanken gauge experiment numerically with the adiabatical insertion of a flux quantum in a belt-shaped sample, in which the absence of level crossing is found under the disorder effect. Without disorder, on the other hand, energy levels do cross each other, which results in an oscillating spin-density-modulation at the sample boundary after the insertion of one flux quantum in the belt-shaped system. But the corresponding net spin transfer is only about one order of magnitude smaller than what is expected from the bulk SHC. These apparently contradictory results can be attributed to the violation of the spin conservation law in such a system. We also briefly address the dissipative Fermi surface contribution to spin polarization, which may be relevant to experimental measurements.

Publisher: name: Lancaster University

description: This research is based on 16 months of ethnographic fieldwork conducted in northern Mozambique in 2015-16. It draws particularly on the 12 months I spent living with a peasant family in a rural neighbourhood, ‘Bairro’. My research focuses on the activities and members of a smallholder producers’ association who, during this period, regularly received the representatives and interventions of six different agricultural commercialisation projects, including a pilot project for the controversial ProSAVANA programme. The thesis explores the contours of everyday life as a smallholder farmer in Bairro, and the ways in which development projects interacted with this everyday landscape, focusing on the key themes of moral economy, food security and land. It considers the workings of power and agency in these interactions and the ways in which they were embodied. It also draws on postcolonial, feminist and critical race scholarship to analyse the research project itself as an auto-ethnographic insight into these dynamics. These readings of everyday life in Bairro draw attention to the complexity and ambivalence of local people’s relationship with development and commercialisation, their agency and vulnerability in constructing livelihoods within a deeply unequal and unpredictable context, and the potential (and actual) complicity of research in reinscribing colonial power relations and subjectivities, with material consequences.

description: The complex WKB-Maslov method is used to consider an approach to the semiclassical integrability of the multidimensional Gross-Pitaevskii equation with an external field and nonlocal nonlinearity previously developed by the authors. Although the WKB-Maslov method is approximate in essence, it leads to exact solution of the Gross-Pitaevskii equation with an external and a nonlocal quadratic potential. For this equation, an exact solution of the Cauchy problem is constructed in the class of trajectory concentrated functions. A nonlinear evolution operator is found in explicit form and symmetry operators (mapping a solution of the equation into another solution) are obtained for the equation under consideration. General constructions are illustrated by examples.

Working Around the CCP’s Insecurities

description: Language is a sensitive matter for the Chinese Communist Party (CCP), a fact made clear by the well-documented mechanisms of party-state censorship and propaganda, which aim to repel criticism and set the agenda in the CCP’s favor. Less widely acknowledged, however, is the extent to which even terms of praise and devotion must be subjected to careful scrutiny in China. Two recent catchphrases in particular that speak anew to deeper anxieties about the image of the CCP and its top leader, Xi Jinping. These are “low-level red” and “high-level black,” odd phrases in English that invite some elucidation. The terms, which first emerged on the internet, refer in both cases to covert or unintentional acts of criticism. “Low-level red,” or dijihong (低級紅), refers in official parlance to language or conduct that is intended to praise the Party or government, but which ultimately has the opposite effect because it is patently false, cheap, or ill-considered. “High-level black,” or gaojihei (高级黑), refers on the other hand to more deliberate and skilful acts of disguised sabotage, in which language is deployed in obscurely humorous ways, or cloaked in academic respectability, in order to criticise or ridicule. 對中國共產黨來說，語言是一個敏感的問題， 這在中國的審查和宣傳機制中得到了充分的證實。審查的目的是為了排斥批評，營造有利於中國共產黨的輿情。然而，鮮為人知的是，在中國，即使是讚美和奉承的詞彙也會受到審查。尤其是最近的兩個流行語 —— "低級紅"和"高級黑"，再次體現了人們對中共及其最高領導人習近平形象的深層憂慮。這兩個詞最早出現在互聯網，均為隱蔽或無意的批評。 "低級紅"指的是那些旨在讚美黨或政府的語言或行為，但最終卻因明顯的虛假、低級或考慮不周而產生相反的效果。而"高級黑"則指更有心機、更有技巧的變相貶低。它以隱晦幽默的方式運用語言，或披上學術的外衣，以達到批評或嘲笑的目的。

description: Federated Learning is a promising machine learning paradigm when multiple parties collaborate to build a high-quality machine learning model. Nonetheless, these parties are only willing to participate when given enough incentives, such as a fair reward based on their contributions. Many studies explored Shapley value based methods to evaluate each party's contribution to the learned model. However, they commonly assume a semi-trusted server to train the model and evaluate the data owners' model contributions, which lacks transparency and may hinder the success of federated learning in practice. In this work, we propose a blockchain-based federated learning framework and a protocol to transparently evaluate each participant's contribution. Our framework protects all parties' privacy in the model building phase and transparently evaluates contributions based on the model updates. The experiment with the handwritten digits dataset demonstrates that the proposed method can effectively evaluate the contributions.

New Censorship, the New Academic Freedom

description: Since 2017 the international Chinese Studies community has been shocked to discover that many of the major commercial academic publishers have been actively working with the Chinese censors to limit access to ‘politically sensitive’ books and articles within the country in order to maintain access to the lucrative Chinese market. This essay examines these incidents and the responses of the publishers upon being discovered—arguing that the convergence of China’s increasingly assertive information control regime and the commercial academic publishers’ thirst for ever more profits has resulted in a new form of institutionalised commercial censorship. 自2017年以來，國際漢學界震驚地發現，許多主流商業學術出版社為了維持自身在利潤豐厚的中國市場的地位，積極與中國審查機構合作，限制中國國內學者和學生對"政治敏感"書籍和文章的獲取。本文剖析此類事件以及出版社在問題曝光之後的回應，進而論證在中國日益嚴格的信息管控與商業出版社對利潤最大化訴求的結合下，一種商業審查制度化的形成。

description: In order to characterize the common feature of the general Lorentz violation models that the local speed of light is variable at ultrahigh energy scale, we introduced a parameter n to characterize the variation of the speed of light between inertial systems. And in order not to violate some fundamental principles and experiments' results, some constraints were imposed on n. Then a coordinate transformation with the parameter n, which meets the symmetry of inertial systems, was naturally obtained. But just to satisfy the symmetry of inertial systems, the expression for n cannot be determined. Inspired by the idea of DSR model, we then discussed a specific expression for n that makes the particle's energy have a limit rather than be infinite derived from the Lorentz model. We found that the modified dispersion relation corresponding to the specific expression for n is deeply associated with the general formula of dispersion relation from the DSR. The motivation of introducing such a parameter n was also discussed. Finally, we discussed the possible LIV effects from astrophysical observations in GRB events and photon annihilation events. Using the data from GRB 190114C we investigated the special dispersion relation obtained in this paper and found that it appears to fit these data better than the two models corresponding to the first or second order approximation of the general formula of dispersion relation. And similar to the other Lorentz violation models corresponding to the subluminal case, the modified dispersion relation obtained in this paper can also result in increasing the energy threshold of photon annihilation reaction, which is expected to be verified by the future energetic photons events.

description: The history of French Sinology is marked by a series of axial dates and prominent names – Jean-Pierre Abel-Rémusat, the Marquis d’Hervey de Saint-Denys, Paul Pelliot and, above all, Édouard Chavannes – who made Francophone studies of China remarkable throughout the nineteenth century, the age of the birth of modern scientific research. Marcel Granet, whose fame outlived his premature death at the beginning of the War, on November 25th 1940, left a durable mark on this history through the alliance that he managed to weave between his sinological knowledge, his study of sociology, brilliant intuitions, and a pedagogical capacity rooted in a writing-style as elegant as it is instructive. He had multiple scholarly talents but was unique in his gift for popularization. It would be possible to summarily divide his work into two great threads, sometimes remarkably entwined: inform the wider educated public about the roots and mysteries of ancient Chinese culture; and share his innovative readings of the documents that for more than two thousand years have formed the foundations of “China knowledge”. It was through this scholarly route that Granet embarked on a brilliant academic career, and that he traced out a path from which he would never depart: that of an innovative, sometimes iconoclastic, interpretation of documents from, for the most part, Antiquity.

description: We perform a lattice simulation to investigate the doubly charmed tetraquark $T^+_{cc}$ observed by the LHCb collaboration, slightly below the $D^{*+}D^0$ threshold, with flavor content $cc\bar{u}\bar{d}$ and isospin-$0$. Two-meson interpolators are implemented to explore the isospin quantum numbers $I=0$ and $I=1$. We observe attraction near the $DD^*$ threshold for $I=0$ and repulsion for $I=1$. Moreover, we also include diquark-antidiquark interpolators to study their effect on the energy spectrum. There is no significant shift in the ground state energy when adding diquark-antidiquark interpolators to the interpolator basis when the heavy quark mass is close to the physical charm quark mass. However, we observe a non-negligible shift in the second energy level. This effect has to be taken into account to extract the scattering amplitude of the $T^+_{cc}$. Finally, with a higher mass (close to the bottom quark), the ground state is shifted down significantly. The simulation is performed on $N_f=2+1$ CLS ensembles with $m_π\simeq 280$ MeV.

From a fit to the Dalitz plot density distribution we obtain a precise measurement of the slope parameters. An alternative parametrization relates the $π^+π^-π^0$ slopes to that for $η\to 3π^0$ showing the consistency of KLOE results for both channels. We also obtain the best confirmation of the $C$-invariance in the $η\toπ^+π^-π^0$ decay.

description: We study the dynamics of fractional branes at toric singularities, including cones over del Pezzo surfaces and the recently constructed Y^{p,q} theories. We find that generically the field theories on such fractional branes show dynamical supersymmetry breaking, due to the appearance of non-perturbative superpotentials. In special cases, one recovers the known cases of supersymmetric infrared behaviors, associated to SYM confinement (mapped to complex deformations of the dual geometries, in the gauge/string correspondence sense) or N=2 fractional branes. In the supersymmetry breaking cases, when the dynamics of closed string moduli at the singularity is included, the theories show a runaway behavior (involving moduli such as FI terms or equivalently dibaryonic operators), rather than stable non-supersymmetric minima. We comment on the implications of this gauge theory behavior for the infrared smoothing of the dual warped throat solutions with 3-form fluxes, describing duality cascades ending in such field theories. We finally provide a description of the different fractional branes in the recently introduced brane tiling configurations.

description: We simulate shells created by supernovae expanding into the interstellar medium (ISM) of the nuclear region of a galaxy, and analyze how the shell evolution is influenced by the supernova (SN) position relative to the galactic center, by the interstellar matter (ISM) density, and by the combined gravitational pull of the nuclear star cluster (NSC) and supermassive black hole (SMBH).We adopted simplified hydrodynamical simulations using the infinitesimally thin layer approximation in 3D (code RING) and determined whether and where the shell expansion may bring new gas into the inner parsec around the SMBH. The simulations show that supernovae occurring within a conical region around the rotational axis of the galaxy can feed the central accretion disk surrounding the SMBH. For ambient densities between 10$^3$ and 10$^5$ cm$^{-3}$, the average mass deposited into the central parsec by individual supernovae varies between 10 to 1000 solar masses depending on the ambient density and the spatial distribution of supernova events. Supernova occurring in the aftermath of a starburst event near a galactic center can supply two to three orders of magnitude more mass into the central parsec, depending on the magnitude of the starburst. The deposited mass typically encounters and joins an accretion disk. The fate of that mass is then divided between the growth of the SMBH and an energetically driven outflow from the disk.

description: In order to show the importance of high spatial resolution observations of extra-galactic sources when compared to observations obtained with larger apertures such as ISO, we present N-band spectra (8-13 um) of some locations in three starburst galaxies. In particular, the two galactic nuclei of the spiral galaxy NGC3256, the compact IR supernebula in the dwarf galaxy IIZw40 and the two brightest IR knots in the central starburst of the WR galaxy He2-10. The spectra have been obtained with TIMMI2 on the ESO 3.6m telescope. An inventory of the spectra in terms of atomic fine-structure lines and molecular bands is presented. We show the great value of these high spatial resolution data at constraining properties such as the extinction in the mid-IR, metallicity or stellar content (age, IMF, etc.). Regarding this, we have constrained the stellar content of the IR compact knot in IIZw40 by using the mid-IR fine-structure lines and setting restrictions on the nebular geometry. Considering the PAH bands, we have constructed a new mid-/far-IR diagnostic diagram based on the 11.2 um PAH and continuum, accessible to ground-based observations. Finally, we find a dependence between the presence or non-presence of PAHs and the hardness of the radiation field as measured by the [SIV]/[NeII] ratio. In particular, sources with PAH emission have in general a [SIV]/[NeII] ratio < 0.35. We investigate possible origins for this relation and conclude that it does not necessarily imply PAH destruction, but could also be explained by the PAH-dust competition for FUV photons.

An Asynchronous Scheme for Rollback Recovery in Message-Passing Concurrent Programming Languages

description: Rollback recovery strategies are well-known in concurrent and distributed systems. In this context, recovering from unexpected failures is even more relevant given the non-deterministic nature of execution, which means that it is practically impossible to foresee all possible process interactions.
 In this work, we consider a message-passing concurrent programming language where processes interact through message sending and receiving, but shared memory is not allowed. In this context, we design a checkpoint-based rollback recovery strategy that does not need a central coordination. For this purpose, we extend the language with three new operators: check, commit, and rollback. Furthermore, our approach is purely asynchronous, which is an essential ingredient to developing a source-to-source program instrumentation implementing a rollback recovery strategy.

description: We show how to map Grothendieck's dessins d'enfants to algebraic curves as Seiberg-Witten curves, then use the mirror map and the AGT map to obtain the corresponding 4d $\mathcal{N}=2$ supersymmetric instanton partition functions and 2d Virasoro conformal blocks. We explicitly demonstrate the 6 trivalent dessins with 4 punctures on the sphere. We find that the parametrizations obtained from a dessin should be related by certain duality for gauge theories. Then we will discuss that some dessins could correspond to conformal blocks satisfying certain rules in different minimal models.

description: Using Path Integral Monte Carlo and the Maximum Entropy method, we calculate the dynamic structure factor of solid $^4$He in the bcc phase at a finite temperature of T = 1.6 K and a molar volume of 21 cm$^3$. Both the single-phonon contribution to the dynamic structure factor and the total dynamic structure factor are evaluated. From the dynamic structure factor, we obtain the phonon dispersion relations along the main crystalline directions, [001], [011] and [111]. We calculate both the longitudinal and transverse phonon branches. For the latter, no previous simulations exist. We discuss the differences between dispersion relations resulting from the single-phonon part vs. the total dynamic structure factor. In addition, we evaluate the formation energy of a vacancy.

description: Performing anomaly detection in hybrid systems is a challenging task since it requires analysis of timing behavior and mutual dependencies of both discrete and continuous signals. Typically, it requires modeling system behavior, which is often accomplished manually by human engineers. Using machine learning for creating a behavioral model from observations has advantages, such as lower development costs and fewer requirements for specific knowledge about the system. The paper presents DAD:DeepAnomalyDetection, a new approach for automatic model learning and anomaly detection in hybrid production systems. It combines deep learning and timed automata for creating behavioral model from observations. The ability of deep belief nets to extract binary features from real-valued inputs is used for transformation of continuous to discrete signals. These signals, together with the original discrete signals are than handled in an identical way. Anomaly detection is performed by the comparison of actual and predicted system behavior. The algorithm has been applied to few data sets including two from real systems and has shown promising results.

description: The k-core of a graph G is the maximal subgraph of G having minimum degree at least k. In 1996, Pittel, Spencer and Wormald found the threshold $λ_c$ for the emergence of a non-trivial k-core in the random graph $G(n,λ/n)$, and the asymptotic size of the k-core above the threshold. We give a new proof of this result using a local coupling of the graph to a suitable branching process. This proof extends to a general model of inhomogeneous random graphs with independence between the edges. As an example, we study the k-core in a certain power-law or `scale-free' graph with a parameter c controlling the overall density of edges. For each k at least 3, we find the threshold value of c at which the k-core emerges, and the fraction of vertices in the k-core when c is εabove the threshold. In contrast to $G(n,λ/n)$, this fraction tends to 0 as εtends to 0.

Non-Neutralized Electric Current of Active Regions Explained as a Projection Effect

Year: 2020

description: Active regions (ARs) often possess an observed net electric current in a single magnetic polarity. We show that such "non-neutralized" currents can arise from a geometric projection effect when a twisted flux tube obliquely intersects the photosphere. To this end, we emulate surface maps of an emerging AR by sampling horizontal slices of a semi-torus flux tube at various heights. Although the tube has no net toroidal current, its poloidal current, when projected along the vertical direction, amounts to a significant non-neutralized component on the surface. If the tube emerges only partially as in realistic settings, the non-neutralized current will 1) develop as double ribbons near the sheared polarity inversion line, (2) positively correlate with the twist, and 3) reach its maximum before the magnetic flux. The projection effect may be important to the photospheric current distribution, in particular during the early stages of flux emergence.

Spatial attention and metacontrast unmasking : integration of the two solitudes
Creators: name: Lamenza, Ernesto A.
Publisher: name: University of British Columbia
Year: 2009

description: This thesis claims that metacontrast unmasking is influenced by attentional orienting towards the target location. This view is contrary to Breitmeyer, Rudd and Dunn (1981), who proposed that metacontrast unmasking is the product of inhibition of the primary mask's transient signal by the sustained signal of a secondary mask. A series of experiments demonstrate the thesis using a task in which observers discriminated the missing corner of a target diamond. Experiments 1 and 2 replicated metacontrast masking and unmasking, respectively, experiment 3 illustrated that contour proximity had no influences on unmasking, contrary to dual-channel inhibition theory. Experiments 4 and 5 indicated that metacontrast unmasking was influenced by spatial orienting. We propose an addition of attention to dual-channel theory as it is incomplete with regards to metacontrast unmasking.
Probing neutrino magnetic moment and unparticle interactions with Borexino

description: We discuss the limits on the neutrino magnetic moment and hypothetical interactions with a hidden unparticle sector, coming from the first neutrino data release of the Borexino experiment. The observed spectrum in Borexino depends weakly on the solar model used in the analysis, since most of the signal comes from the mono-energetic 7Be neutrinos. This fact allows us to calibrate the nu-e scattering cross section through the spectral shape. In this way, we have derived a limit on the magnetic moment for the neutrinos coming from the Sun (in which a nu_mu and nu_tau component is present): mu_nu<8.4E-11 mu_B (90%CL) which is comparable with those obtained from low energy reactor experiments. Moreover, we improve the previous upper limit on magnetic moment of the nu_tau by three orders of magnitude and the limit on the coupling constant of the neutrino with a hidden unparticle sector.

description: The consistently low activity level of the old solar analog 51 Peg not only facilitated the discovery of the first hot Jupiter, but also led to the suggestion that the star could be experiencing a magnetic grand minimum. However, the 50 year time series showing minimal chromospheric variability could also be associated with the onset of weakened magnetic braking (WMB), where sufficiently slow rotation disrupts cycling activity and the production of large-scale magnetic fields by the stellar dynamo, thereby shrinking the Alfven radius and inhibiting the efficient loss of angular momentum to magnetized stellar winds. In this Letter, we evaluate the magnetic evolutionary state of 51 Peg by estimating its wind braking torque. We use new spectropolarimetric measurements from the Large Binocular Telescope to reconstruct the large-scale magnetic morphology, we reanalyze archival X-ray measurements to estimate the mass-loss rate, and we detect solar-like oscillations in photometry from the Transiting Exoplanet Survey Satellite, yielding precise stellar properties from asteroseismology. Our estimate of the wind braking torque for 51 Peg clearly places it in the WMB regime, driven by changes in the mass-loss rate and the magnetic field strength and morphology that substantially exceed theoretical expectations. Although our revised stellar properties have minimal consequences for the characterization of the exoplanet, they have interesting implications for the current space weather environment of the system.
