Shadow-Lines

Abstract Zainul Abedin, the master-artist of post-1947 East Pakistan and current Bangladesh is an artist firmly marked by his iconic sketches of hunger and displacement from the famine years of 1943–1944 in wartime colonial Bengal. Abedin's famine sketches triggered a milieu of social realism in pre-partition Bengal, a space shared with a growing left-wing cultural activism that patronised realism as progressive art. The late-1940s splintered this radical aesthetic, not only with the diffusion of the Left's cultural agenda, but the displacement of artists like Abedin into post-partition East Pakistan. While the famine itself cast a long shadow on the socio-economic fabric of postcolonial Bengal, partition in 1947 refracted its shadows in multiple ways. In India, (West) Bengal bore the fault-lines of 1943 and 1947, constituting almost, the shadows of Nehruvian national-modern promise. In East Pakistan, the Abedin's visual ethic of social realism inhabited the multiple planes the artist negotiated across the long decolonisation in India and Pakistan: as a displaced refugee from Calcutta, as artist-bureaucrat of post-1947 Pakistan, and the pedagogue-aesthete of post-liberation Bangladesh. Exploring Abedin's continued interfaces with the famine of 1943, this paper will place him as that rare story-teller of decolonisation in South Asia, who both invoked and forged its shadows and afterlives.
Prototyping tools and techniques

We begin with our definition of a prototype and then discuss prototypes as design artifacts, introducing four dimensions for analyzing them. We then discuss the role of prototyping within the design process, in particular the concept of a design space, and how it is expanded and contracted by generating and selecting design ideas. The next three sections describe specific prototyping approaches: Rapid prototyping, both off-line and on-line, for early stages of design, iterative prototyping, which uses on-line development tools, and evolutionary prototyping, which must be based on a sound software architecture.
Diffusion Centrality in Social Networks

Though centrality of vertices in social networks has been extensively studied, all past efforts assume that centrality of a vertex solely depends on the structural properties of graphs. However, with the emergence of online "semantic" social networks where vertices have properties (e.g. gender, age, and other demographic data) and edges are labeled with relationships (e.g. friend, follows) and weights (measuring the strength of a relationship), it is essential that we take semantics into account when measuring centrality. Moreover, the centrality of a vertex should be tied to a diffusive property in the network - a Twitter vertex may have high centrality w.r. t. jazz, but low centrality w.r. t. Republican politics. In this paper, we propose a new notion of diffusion centrality (DC) in which semantic aspects of the graph, as well as a diffusion model of how a diffusive property p is spreading, are used to characterize the centrality of vertices. We present a hyper graph based algorithm to compute DC and report on a prototype implementation and experiments showing how we can compute DCs (using real YouTube data) on social networks in a reasonable amount of time. We compare DC with classical centrality measures like degree, closeness, betweenness, eigenvector and stress centrality and show that in all cases, DC produces higher quality results. DC is also often faster to compute than both betweenness, closeness and stress centrality, but slower than degree and eigenvector centrality.
Nicotinic agonists stimulate acetylcholine release from mouse interpeduncular nucleus: a function mediated by a different nAChR than dopamine release from striatum

Acetylcholine release stimulated by nicotinic agonists was measured as radioactivity released from perfused synaptosomes prepared from mouse interpeduncular nucleus (IPN) that had been loaded with [3H]choline. Agonist‐stimulated release was dependent upon external calcium and over 90% of released radioactivity was acetylcholine. The release process was characterized by dose response curves for 13 agonists and inhibition curves for six antagonists. α‐Conotoxin MII did not inhibit this release, while α‐conotoxin AuIB inhibited 50% of agonist‐stimulated release. Comparison of this process with [3H]dopamine release from mouse striatal synaptosomes indicated that different forms of nicotinic acetylcholine receptors (nAChRs) may mediate these processes. This was confirmed by assays using mice homozygous for the β2 subunit null mutation. The deletion of the β2 subunit had no effect on agonist‐stimulated acetylcholine release, but abolished agonist‐stimulated release of dopamine from striatal synaptosomes. Mice heterozygous for the β2 subunit null mutation showed decreased dopamine release evoked by l‐nicotine with no apparent change in EC50 value, as well as similar decreases in both transient and persistent phases of release with no changes in desensitization rates.
Planting Poetry: Sowing Seeds of Creativity in a Year 5 Class

Abstract This article offers a case study account of a garden-themed poetry writing project run by a creative writing organisation in partnership with a class of 9–10-year-old children from a London primary school. I explore the concept of creativity which framed the five-week project and analyse the different ways in which the creative practitioner worked collaboratively with the class teacher to develop children’s writing, not least by adopting an open, inclusive pedagogy. Despite the obvious successes of this project, I raise questions about the role of creative practitioners working in schools and the ways in which special projects locate creativity on the margins of the mainstream curriculum.
MicroRNA-135a Inhibits Cell Proliferation by Targeting Bmi1 in Pancreatic Ductal Adenocarcinoma

Pancreatic ductal adenocarcinoma (PDAC) is a highly lethal solid tumor due to the lack of reliable early detection markers and effective therapies. MicroRNAs (miRNAs), noncoding RNAs that regulate gene expression, are involved in tumorigenesis and have a remarkable potential for the diagnosis and treatment of malignancy. In this study, we investigated aberrantly expressed miRNAs involved in PDAC by comparing miRNA expression profiles in PDAC cell lines with a normal pancreas cell line and found that miR-135a was significantly down-regulated in the PDAC cell lines. The microarray results were validated by qRT-PCR in PDAC tissues, paired adjacent normal pancreatic tissues, PDAC cell lines, and a normal pancreas cell line. We then defined the tumor-suppressing significance and function of miR-135a by constructing a lentiviral vector to express miR-135a. The overexpression of miR-135a in PDAC cells decreased cell proliferation and clonogenicity and also induced G1 arrest and apoptosis. We predicted Bmi1 may be a target of miR-135a using bioinformatics tools and found that Bmi1 expression was markedly up-regulated in PDAC. Its expression was inversely correlated with miR-135a expression in PDAC. Furthermore, a luciferase activity assay revealed that miR-135a could directly target the 3'-untranslated region (3'-UTR) of Bmi1. Taken together, these results demonstrate that miR-135a targets Bmi1 in PDAC and functions as a tumor suppressor. miR-135a may offer a new perspective for the development of effective miRNA-based therapy for PDAC.
The Feldstein-Horioka Puzzle and Law

In this paper, we introduce a proxy for the legal protection of investors, a dummy variable that indicates legal origins, into the Feldstein and Horioka (1980, Economic Journal 90) saving-investment regression. The estimations show that in the French-civil-law countries, which have the weakest investor protection, the domestic investment rates are generally less strongly correlated with the domestic saving rates. This implies that in countries with less investor protection, the capital resulting from an increase of domestic saving tends to flow to foreign countries with stronger investor protection, rather than into domestic investment.
Acquisition of Unknown Word Paradigms for Large-Scale Grammars

Unknown words are a major issue for large-scale grammars of natural language. We propose a machine learning based algorithm for acquiring lexical entries for all forms in the paradigm of a given unknown word. The main advantages of our method are the usage of word paradigms to obtain valuable morphological knowledge, the consideration of different contexts which the unknown word and all members of its paradigm occur in and the employment of a full-blown syntactic parser and the grammar we want to improve to analyse these contexts and provide elaborate syntactic constraints. We test our algorithm on a large-scale grammar of Dutch and show that its application leads to an improved parsing accuracy.
Temporally consistent disparity maps from uncalibrated stereo videos

We address the problem of computing a sequence of dense disparity maps from two synchronized video streams recorded by slightly displaced cameras. Generating such disparity videos is becoming increasingly important in the light of new autostereoscopic displays and novel viewpoint applications. We propose a good-quality, computationally fast and easy-to-use solution to accomplish this task. This paper describes the four major steps of our 2D to 3D video conversion procedure. (1) The user segments the video into its scenes. (2) For each scene, we rectify the uncalibrated stereo pairs so that correspondences lie on the same horizontal scanline. (3) A fast and accurate dynamic programming-based stereo matcher is then applied to compute a dense disparity map for each stereo pair. (4) We perform temporal smoothing on the computed disparity sequence to reduce the disparity flickering problem. All of these functionalities can be accessed via an easy-to-use graphical user interface, which makes our conversion procedure applicable even for technical unskilled users. We demonstrate the good quality of our results using various challenging real-world stereo streams.
Hyper-Fisher Vectors for Action Recognition

In this paper, a novel encoding scheme combining Fisher vector and bag-of-words encodings has been proposed for recognizing action in videos. The proposed Hyper-Fisher vector encoding is sum of local Fisher vectors which are computed based on the traditional Bag-of-Words (BoW) encoding. Thus, the proposed encoding is simple and yet an effective representation over the traditional Fisher Vector encoding. By extensive evaluation on challenging action recognition datasets, viz., Youtube, Olympic Sports, UCF50 and HMDB51, we show that the proposed Hyper-Fisher Vector encoding improves the recognition performance by around 2-3% compared to the improved Fisher Vector encoding. We also perform experiments to show that the performance of the Hyper-Fisher Vector is robust to the dictionary size of the BoW encoding.
Astrophysical water masers: Line profiles analysis

The changes in the spectral line profile of the 22 GHz H 2 O maser are calculated as a function of emerging maser flux. We address not only the narrowing and re-broadening of the maser lines, but also the deviations of Gaussian symmetry as a result of the various hyperfine components of the 22 GHz maser line. Non-LTE models of the H 2 O maser transition, including hyperfine structure and cross-relaxation, are compared with high spectral resolution Very Long Baseline Interferometry (VLBI) observations of the H 2 O masers in the circumstellar envelopes (CSEs) of a sample of late-type stars. This yields estimates on the thermal width in the maser region as well as the emerging maser flux and thus the level of saturation. We also discuss the effect of a velocity gradient along the maser path on the line widths and shapes of the line profile and the effect of the geometry of the maser region. We find that the typical velocity shift along the maser path is of the order of 1.0 km s -1 . The effect of this shift on the shape of the maser spectrum is difficult to distinguish from the effect of the hyperfine components.
Conditions for transverse-regularity of serial manipulators

Transverse-regularity is a point-wise manipulator property, ensuring that the singular set Sigma is locally a smooth manifold. A generic manipulator is one which is transverse-regular in any configuration. This paper gives a necessary and sufficient condition for transverse-regularity. The condition requires the manipulator's joint screws and their screw products. An expression for the tangent space to Sigma at transverse-regular singularities is derived. It is shown that a manipulator is non-generic if it can attain a pose where the rank of the manipulator's screw system together with the screw products is not the maximal rank of the Jacobian. A necessary and sufficient criterion for degree-one singularities is given in terms of the mechanism' joint screws. In particular, any non-redundant manipulator is transverse-regular in a degree-one singularity.
Fate of clumps in damped Lyα systems

Recent observations have revealed that damped Lyα clouds (DLAs) host star formation activity. In order to examine if such star formation activity can b e triggered by ionization fronts, we perform high-resolution hydrodynamics and radiative transfer simulations of the effect of radiative feedback from propagating ionization fronts on high-density clumps. We examine two sources of ultraviolet (UV) radiation field to which high-redshift ( z � 3) galaxies could be exposed: one corresponding to the UV radiation originating from stars within the DLA, itself, and the other corresponding to the UV background radiation. We find that, for larger clouds, the propagating I-fronts created by local stellar s ources can trigger cooling instability and collapse of significant part, up to 85%, of the cloud, crea ting conditions for star formation in a timescale of a few Myr. The passage of the I-front also triggers collapse of smaller clumps (with radii below � 4 pc), but in these cases the resulting cold and dense gas does not reach conditions conducive to star formation. Assuming that 85% of the gas initially in the clump is converted into stars, we obtain a star formation rate of � 0.25 M⊙ yr −1 kpc −2 . This is somewhat higher than the value derived from recent observations. On the other hand, the background UV radiation which has harder spectrum fails to trigger coolin g and collapse. Instead, the hard photons which have long mean-free-path heat the dense clumps, which as a result expand and essentially dissolve in the ambient medium. Therefore, the star formation activity in DLAs is strongly regulated by the radiative feedback, both from the external UV background and internal stellar sources and we predict quiescent evolution of DLAs (not starburst-like evolution).
Transfering saturation, the finite cover property, and stability

Abstract Saturation is (μ, κ)-transferable in T if and only if there is an expansion T 1 of T with |T 1| = |T| such that if M is a μ-saturated model of T 1 and |M| ≥ κ then the reduct M|L(T) is κ-saturated. We characterize theories which are superstable without f.c. p., or without f.c. p. as, respectively those where saturation is (ℵ0, λ)-transferable or (κ(T), λ)-transferable for all λ. Further if for some μ ≥ |T|,2 μ > μ +, stability is equivalent to for all μ ≥ |T|, saturation is (μ, 2 μ )-transferable.
Lexical Retuning Targets Features

Previous work has shown that listeners systematically ``retune'' their categorical boundaries when presented with real-word tokens containing an ambiguous segment. There have been multiple previous studies on this lexically-guided retuning (Eisner and Mc- Queen 2005; McQueen et al. 2006; Norris et al. 2003), but the level of representation that retuning targets is not entirely clear. In this paper, we show that retuning occurs at the level of features for fricatives. Given that previous research has argued similarly for stops (Kraljic & Samuel 2006), we suggest that retuning generally targets featural representations.
Performance Analysis of Multimedia Applications using Correlated Streams

In modern embedded systems, data streams are often partitioned into separate sub-streams which are processed on parallel hardware components. To analyze the performance of these systems with high accuracy, correlations between event streams must be taken into account. No methods are known so far that are able to model such a scenario with the desired accuracy. In this paper, we present a new approach to analyze correlations and we embed this analysis method into a well-established modular performance analysis framework. The presented approach enables system-level performance analysis of complete systems by taking into account stream correlations and blocking-read semantics. Experimental results on a hardware-software prototyping system are provided that show the accuracy of the analysis in a practical application
Collaborative climate and effectiveness of knowledge work - an empirical study

Suggests that collaborative climate is one of the major factors influencing effectiveness of knowledge work. Discusses the concept of collaborative climate and develops a survey instrument to measure it. Presents results based on data from 8,277 respondents in a wide variety of public and private sector organisations. Collaborative climate tends to improve with age, education level and managerial role. It is generally better in private firms, and seems to peak with mid‐size firm level. Employees tend to experience a U‐formed appreciation of the collaborative climate. Theories proposing that people reach a “professional plateau” (an S‐formed curve) have been supported to some degree. Finally, collaborative climate in the private sector is generally better than in the public sector. Uses the data to identify gaps and potentials for improving effectiveness. Further investigates two cases of good and bad practice and identifies strengths and weaknesses.
Dementia in older people admitted to hospital: a regional multi-hospital observational study of prevalence, associations and case recognition

Background: previous studies have indicated a prevalence of dementia in older admissions of ∼42% in a single London teaching hospital, and 21% in four Queensland hospitals. However, there is a lack of published data from any European country on the prevalence of dementia across hospitals and between patient groups. Objective: to determine the prevalence and associations of dementia in older patients admitted to acute hospitals in Ireland. Methods: six hundred and six patients aged ≥70 years were recruited on admission to six hospitals in Cork County. Screening consisted of Standardised Mini-Mental State Examination (SMMSE); patients with scores <27/30 had further assessment with the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE). Final expert diagnosis was based on SMMSE, IQCODE and relevant medical and demographic history. Patients were screened for delirium and depression, and assessed for co-morbidity, functional ability and nutritional status. Results: of 598 older patients admitted to acute hospitals, 25% overall had dementia; with 29% in public hospitals. Prevalence varied between hospitals (P < 0.001); most common in rural hospitals and acute medical admissions. Only 35.6% of patients with dementia had a previous diagnosis. Patients with dementia were older and frailer, with higher co-morbidity, malnutrition and lower functional status (P < 0.001). Delirium was commonly superimposed on dementia (57%) on admission. Conclusion: dementia is common in older people admitted to acute hospitals, particularly in acute medical admissions, and rural hospitals, where services may be less available. Most dementia is not previously diagnosed, emphasising the necessity for cognitive assessment in older people on presentation to hospital.
The quadratic isoperimetric inequality for mapping tori of free group automorphisms II: The general case

If F is a finitely generated free group and \phi is an automorphism of F then the mapping torus of \phi admits a quadratic isoperimetric inequality. This is the third and final paper in a series proving this theorem. The first two were math.GR/0211459 and math.GR/0507589.
Constructing Bayesian networks by integrating gene expression and copy number data identifies NLGN4Y as a novel regulator of prostate cancer progression

To understand the heterogeneity of prostate cancer (PCa) and identify novel underlying drivers, we constructed integrative molecular Bayesian networks (IMBNs) for PCa by integrating gene expression and copy number alteration data from published datasets. After demonstrating such IMBNs with superior network accuracy, we identified multiple sub-networks within IMBNs related to biochemical recurrence (BCR) of PCa and inferred the corresponding key drivers. The key drivers regulated a set of common effectors including genes preferentially expressed in neuronal cells. NLGN4Y—a protein involved in synaptic adhesion in neurons—was ranked as the top gene closely linked to key drivers of myogenesis subnetworks. Lower expression of NLGN4Y was associated with higher grade PCa and an increased risk of BCR. We show that restoration of the protein expression of NLGN4Y in PC-3 cells leads to decreased cell proliferation, migration and inflammatory cytokine expression. Our results suggest that NLGN4Y is an important negative regulator in prostate cancer progression. More importantly, it highlights the value of IMBNs in generating biologically and clinically relevant hypotheses about prostate cancer that can be validated by independent studies.
Personalized Recommendation for Public Transportation Using User Context

This paper presents a new application of public transit guide system named PATRASH (Personalized Autonomous TRAansit recommendation System considering user context and History). Although existing transit guide systems provide a lot of functions, their users can not always use all the functions under their control because of the complexity of the functions. Under this situation, we developed and supply PATRASH to reduce complicated user operations. PATRASH provides simple functions users can easily use. The concept of PATRASH is “First Show, Second Search. ” PATRASH displays routes and time table information recommended to the users. If they need, they can search another route. The target users of PATRASH are transit riders who come to Ito campus of Kyushu university. Ito campus locates in a rural area and has four routes run by three bus transportation companies and connected to a railroad or a subway. Since the main route usually used by each transit rider seems to be almost determined, we believe personalized function of PATRASH becomes more and more important. To realize the concept of PATRASH and give simple usability to the users, we propose a new 3D adaptive interface and release PATRASH to the public. We also present a preliminal case study of PATRASH project.
