Identification of a novel secretion system in Leishmania : composition, mechanisms, and immune modulating properties
Creators: name: Silverman, Judith Maxwell
Publisher: name: University of British Columbia
Year: 2010

description: Human infection with protozoa of the genus Leishmania results in a spectrum of disease manifestations collectively termed the leishmaniases. These diseases involve a chronic infection of macrophages which display a deactivated phenotype. Various proteins secreted by leishmania are known to interact with host signaling molecules, bringing about activation of negative feedback loops. Some of these have been shown to block interferon-γ signaling and to inhibit macrophage microbicidal functions. Unlike the well characterized secretion mechanisms used by bacterial pathogens, the mechanism(s) by which leishmania and other eukaryotic pathogens secrete proteins into host cells has remained elusive. The overall aim of this project was to gain a more thorough understanding of host immune-modulation by leishmania, based on the hypothesis that much of these effects are mediated by secreted proteins. The project goals were to: 1) comprehensively identify the proteins secreted by leishmania, 2) determine the mechanism by which proteins are secreted from leishmania into host cells, and 3) determine the functional properties of leishmania secreted compounds. To achieve these goals, a global proteomic analysis of leishmania secreted proteins was carried out using quantitative mass spectrometry. This identified 358 bona fide leishmania secreted proteins many of which were orthologs of proteins considered to be markers of mammalian exosomes. Subsequent experiments confirmed that leishmania secrete exosomes into conditioned media. Comparative proteomics showed that exosomes account for at least 50% of protein secretion by leishmania. Furthermore, the results showed that the cargo profile of leishmania exosomes is influenced by changes in temperature and pH, similar to those experienced by promastigotes after host invasion. Microscopy of leishmania infected cells confirmed the novel finding that leishmania use exosomes to deliver proteins into host cells. Additional studies demonstrated that leishmania exosomes have immunosuppressive properties which, in a cargo dependent manner, modulate the responses of monocytes, dendritic cells, and T lymphocytes. These findings suggest that leishmania utilize exosomes in long-range cellular communication and immune-modulation. In conclusion, this research has significantly advanced the current knowledge of leishmania biology, through the identification of novel secreted molecules, discovery of a secretion system, and description of the immune-modulating effects of leishmania exosomes.

description: The basic goal of human computer interaction is to improve the interaction between users and computers by making computers more usable and receptive to the user's needs. Within this context, the use of hand postures in replacement of traditional devices such as keyboards, mice and joysticks is being explored by many researchers. The goal is to interpret human postures via mathematical algorithms. Hand posture recognition has gained popularity in recent years, and could become the future tool for humans to interact with computers or virtual environments. An exhaustive description of the frequently used methods available in literature for hand posture recognition is provided. It focuses on the different types of sensors and data used, the segmentation and tracking methods, the features used to represent the hand postures as well as the classifiers considered in the recognition process. Those methods are usually presented as highly robust with a recognition rate close to 100%. However, a couple of critical points necessary for a successful real-time hand posture recognition system require major improvement. Those points include the features used to represent the hand segment, the number of postures simultaneously recognizable, the invariance of the features with respect to rotation, translation and scale and also the behavior of the classifiers against non-perfect hand segments for example segments including part of the arm or missing part of the palm. A 3D time-of-flight camera named SR4000 has been chosen to develop a new methodology because of its capability to provide in real-time and at high frame rate 3D information on the scene imaged. This sensor has been described and evaluated for its capability for capturing in real-time a moving hand. A new recognition method that uses the 3D information provided by the range camera to recognize hand postures has been proposed. The different steps of this methodology including the segmentation, the tracking, the hand modeling and finally the recognition process have been described and evaluated extensively. In addition, the performance of this method has been analyzed against several existing hand posture recognition techniques found in literature. The proposed system is able to recognize with an overall recognition rate of 98% and in real-time 18 out the 33 postures of the American Sign Language alphabet. This recognition is translation, rotation and scale invariant.

description: Reliable single photon sources constitute the basis of schemes for quantum communication and measurement based quantum computing. Solid state single photon sources based on quantum dots are convenient and versatile but the electronic transitions that generate the photons are subject to interactions with lattice vibrations. Using a microscopic model of electron-phonon interactions and a quantum master equation, we here examine phonon-induced decoherence and assess its impact on the rate of production, and indistinguishability, of single photons emitted from an optically driven quantum dot system. We find that, above a certain threshold of desired indistinguishability, it is possible to mitigate the deleterious effects of phonons by exploiting a three-level Raman process for photon production.

description: Цель работы – изучить особенности фармакоинвазивной тактики ведения пациентов с острым инфарктом миокарда с подъемом сегмента ST (ОИМпST). Материалы и методы. В исследование включены пациенты с диагнозом ОИМпST. Изучали факторы риска, гемодинамические показатели и лабораторную характеристику пациентов на госпитальном этапе лечения. Оценивали госпитальную летальность больных по шкале GRACE. Статистическая обработка с применением пакета программ Statistica 10.0. Результаты. Пациенты с ОИМпST разделены на группы чрескожного коронарного вмешательства (ЧКВ), тромболитической терапии (ТЛТ) и ТЛТ+ЧКВ. Возраст больных в группе ЧКВ и ТЛТ+ЧКВ был сопоставим, а пациенты в группе догоспитальной ТЛТ были старше. По шкале госпитальной летальности GRACE пациенты после ТЛТ имели наивысший бал (р<0,05), а больные после ЧКВ и ТЛТ+ЧКВ не отличались (р>0,05). В первые сутки ОИМпST уровень N – терминального фрагмента мозгового натрийуретического пептида (NTproBNP) и стимулирующего фактора роста (ST-2) увеличивался. Фармакоинвазивная тактика ведения пациентов с ОИМпST приводила к снижению показателей NT-proBNP и стимулирующего фактора роста ST-2 на госпитальном этапе лечения по сравнению с пациентами после ТЛТ, ЧКВ. Заключение. Фармакоинвазивная тактика ведения пациентов с ОИМпST приводит к снижению значений NT-proBNP и ST-2, отражая более благоприятный прогноз пациентов. Референтных значений ST-2 достигают пациенты ОИМпST после ЧКВ и фармакоинвазивной терапии.

description: Charged current Drell-Yan production at hadron colliders is a benchmark electroweak process. A recent measurement of the W boson mass by the CDF experiment displays a large deviation from the Standard Model prediction. To enable precision phenomenology for this process, we compute the third-order (N$^3$LO) QCD corrections to the rapidity distribution in W boson production and to the transverse mass distribution of its decay products. We study kinematic regions relevant for the LHC experiments and assess the numerical magnitude of uncertainties from electroweak input parameters and parton distribution functions.

Magnetocaloric effect (MCE) in the obtained samples has been measured by two independent methods: by classical direct methodic and by a method of magnetic field modulation. The values of MCE obtained by both methods have been substantially differed. The explanation of the observed divergences is given. The correlation between the level of doping and MCE value has been defined. The value of TC determined by the MCE maximum has been conformed to the literature data received by other methods.

description: The objective of this study was to examine the efficacy of a comprehensive decolonization treatment in reducing methicillin-resistant Staphylococcus aureus (MRSA) carriage among an outpatient population. Patients colonized with MRSA were randomized to receive pharmacological decolonization treatment or no treatment. The primary outcome was detection of MRSA at 3 months. Occurrence of MRSA infection was assessed at 6 months. Molecular analyses were performed on all MRSA isolates. Of 205 patients, 15 (7%) were enrolled into the study (9 treatment; 6 control). At 3 months, 4/8 (50%) in the treatment group had eradication and none in the control group (0/4, 0%). Infection occurred in 5 patients (3 treatment; 2 control). All of the MRSA isolates were community-associated MRSA strain types with USA300 accounting for 87%. Among persistent CA-MRSA carriers, our decolonization treatment was well tolerated. However, enrollment was limited. Future studies with different enrollment strategies are required.

description: Previous research and theorizing on unforgiveness has largely focused on the emotional – ruminative aspect of the phenomenon and adverse consequences to health and relationships that are associated with it. In contrast to this, my analysis of fourteen semi-structured interviews with victims of interpersonal offenses indicates that unforgiveness is a much more multi-faceted and nuanced experience. Based on participants’ responses, I identified a possible model of unforgiveness that includes the emotional – ruminative and cognitive dimensions of unforgiveness, as well as a number of components – inner conflict, barriers to forgiveness, and strategies for resolving inner conflict – that affect where a victim of an interpersonal transgression may be charted along the two dimensions. Implications for conceptualizing unforgiveness and directions for future research are discussed.

description: The objective of the report is to identify enabling and hindering factors for the uptake of ICT solutions to water governance, through the analysis of the process of development and the introduction of three digital applications in three different contexts of water management. This present document represents a preliminary version for the final deliverable 3.4 for WP3 to be delivered in M30. The report applies the structure proposed in the Guiding Protocol (Deliverable 3.1). Following this structure, the report first describes the general case context of Berlin, Paris and Milan before turning to the assessment of the digital water governance system in the three case studies. In a second step, the social context of the use of the digital solutions will be evaluated. As such, collected findings in this report are still preliminary and, so far, not every hypothesis defined in the Guiding Protocol has been inquired thoroughly. Nevertheless, current research has reached good progress, reflected in the current status of this report. The first sets of stakeholders’ interviews and community of practices were conducted and allowed to delineate the structural configurations of water governance specific to the different case studies. They expose elements that might prove to be factors and conjunctions that affect – positively or negatively – the uptake of digital solutions and the coordination among involved actors.
 The process of development of the three applications – ICT solutions – in Berlin, Milan and Paris proceeds in parallel to the sociological research on the respective systems of water governance. Thanks to regular communication and exchanges, digital solutions will be developed accordingly with the study cases’ own specificity, to ensure that, once finalized these will be effectively used by people and will thus support a digital and sustainable transition of the water systems.

description: Named Entity Recognition (NER) systems play a vital role in NLP applications such as machine translation, summarization, and question-answering. These systems identify named entities, which encompass real-world concepts like locations, persons, and organizations. Despite extensive research on NER systems for the English language, they have not received adequate attention in the context of low resource languages. In this work, we focus on NER for low-resource language and present our case study in the context of the Indian language Marathi. The advancement of NLP research revolves around the utilization of pre-trained transformer models such as BERT for the development of NER models. However, we focus on improving the performance of shallow models based on CNN, and LSTM by combining the best of both worlds. In the era of transformers, these traditional deep learning models are still relevant because of their high computational efficiency. We propose a hybrid approach for efficient NER by integrating a BERT-based subword tokenizer into vanilla CNN/LSTM models. We show that this simple approach of replacing a traditional word-based tokenizer with a BERT-tokenizer brings the accuracy of vanilla single-layer models closer to that of deep pre-trained models like BERT. We show the importance of using sub-word tokenization for NER and present our study toward building efficient NLP systems. The evaluation is performed on L3Cube-MahaNER dataset using tokenizers from MahaBERT, MahaGPT, IndicBERT, and mBERT.

Rainfall interception in an urban environment
Creators: name: Asadian, Yeganeh
Publisher: name: University of British Columbia
Year: 2010

description: Vegetation interception loss plays an important role in controlling the water balance of a watershed, especially where urban development has taken place. The aim of this study is to document the importance of urban trees as a form of ‘green infrastructure’ to reduce stormwater runoff and rainwater intensity, and cause a delay in precipitation reaching the ground. A 21 months study was carried out in the North/West Vancouver in British Columbia to determine how effective urban trees are to intercept and detain rainwater. We applied a unique methodology for measuring rain/throughfall under 54 different urban trees using a system of PVC pipes hung beneath the canopy to capture the throughfall where it drained into a rain gauge attached to a data logger. To ensure that the study adequately captured the range of throughfall variability, trees were selected to sample different landscape sites (streets, parks, and natural forested areas), elevations, tree type, health condition and species, including Douglas-fir (Pseudotsuga menziesii), Western red cedar (Thuja plicata), Bigleaf maple (Acer macrophyllum), Oak (Quercus sp.), Copper beech (Fagus sylvatica), Horse chestnut (Aesculus hippocastanum), Cherry (Prunus sp.), and Poplar (Populus sp.). Interception loss and throughfall were monitored from February 2007 until November 2008. Rainfall interception varied seasonally for all species. Interception losses accounted for on average 76.5% and 56.4% of gross precipitation for coniferous and deciduous trees, respectively. The interception loss varied depending on canopy structure, climatic conditions, and rainfall characteristics. The results showed that urban trees intercept and evapotranspire more rain than trees in forested environments. Together with the delay in runoff trees can act as an effective stormwater management tool on individual properties.

description: This research explores the complex phenomenon of innovation in projects. Studies on the relationship between organizational performance and innovation have produced useful, but conflicting results. I attempt to examine the effect of predictors from firm-level, project-level, and individual-level on the innovative behaviour in projects. An extensive body of literature proposes that poor performance in a declining firm is needed to catalyze the search for new ideas or practices. Another body of literature views the availability of slack resources resulting from exceptional performance as the facilitator of innovation. The theoretical propositions and the framework presented in this study were based on these two domains of study. The findings of this study suggested that certain types of innovation were predominant in over-performing projects, while other types of innovation were only present in under-performing projects. There were statistically significant differences between innovation in over-performing projects and those in under-performing ones. The study found the difference was related to neither the types of innovation between the two groups, nor whether the innovation occurs under one condition or the other. Finally, the results showed that the expected effect of innovation in over-performing projects was found to be contributing to the effectiveness-related measures of project performance (i.e., social and environmental measures) only under both levels of performance. In under-performing projects, however, neither efficiency nor effectiveness measures of project performance were affected by innovative actions.
VIPERS II : a soft-core vector processor with single-copy scratchpad memory

Publisher: name: University of British Columbia
Year: 2010

description: Previous work has demonstrated soft-core vector processors in FPGAs can be applied to speed up data-parallel embedded applications, while providing the users an easy-to-use platform to tradeoff performance and area. However, its performance is limited by load and store latencies, requiring extra software design effort to optimize performance. This thesis presents VIPERS II, a new vector ISA and the corresponding microarchitecture, in which the vector processor reads and writes directly to a scratchpad memory instead of the vector register file. With this approach, the load and store operations and their inherent latencies can often be eliminated if the working set of data fits in the vector scratchpad memory. Moreover, with the removal of load/store latencies, the user doesn't have to use loop unrolling to enhance performance, reducing the amount of software effort required and making the vectorized code more compact. The thesis shows the new architecture has the potential to achieve performance similar to that of the unrolled versions of the benchmarks, without actually unrolling the loop. Hardware performance results of VIPERS II demonstrated up to 47x speedup over a Nios II processor with only 13x more resources used.

description: We use images of high spatial and temporal resolution, obtained with the Rapid Oscillations in the Solar Atmosphere instrument at the Dunn Solar Telescope, to reveal how the generation of transverse waves in Type I spicules is a direct result of longitudinal oscillations occurring in the photosphere. Here we show how pressure oscillations, with periodicities in the range 130 - 440 s, manifest in small-scale photospheric magnetic bright points, and generate kink waves in the Sun's outer atmosphere with transverse velocities approaching the local sound speed. Through comparison of our observations with advanced two-dimensional magneto-hydrodynamic simulations, we provide evidence for how magnetoacoustic oscillations, generated at the solar surface, funnel upwards along Type I spicule structures, before undergoing longitudinal-to-transverse mode conversion into waves at twice the initial driving frequency. The resulting kink modes are visible in chromospheric plasma, with periodicities of 65 -220 s, and amplitudes often exceeding 400 km. A sausage mode oscillation also arises as a consequence of the photospheric driver, which is visible in both simulated and observational time series. We conclude that the mode conversion and period modification is a direct consequence of the 90 degree phase shift encompassing opposite sides of the photospheric driver. The chromospheric energy flux of these waves are estimated to be approximately 300,000 W/m^2, which indicates that they are sufficiently energetic to accelerate the solar wind and heat the localized corona to its multi-million degree temperatures.

description: Studying a centi-parsec supermassive black hole binary (SMBHB) would allow us to explore a new parameter space in active galactic nuclei, and these objects are also potential sources of gravitational waves. We report evidence that an SMBHB with an orbital period of about 30 yr may be resident in the nearby galactic nucleus M81. This orbital period and the known mass of M81 imply an orbital separation of about 0.02 pc. The jet emanating from the primary black hole showed a short period of jet wobbling at about 16.7 yr, superposing a long-term precession at a timescale of several hundred years. Periodic radio and X-ray outbursts were also found two times per orbital period, which could be explained by a double-peaked mass accretion rate variation per binary orbit. If confirmed, M81 would be one of the closest SMBHB candidates, providing a rare opportunity to study the final parsec problem.

Despite their dissimilarities, through the controversial relation they both had with Soviet authority, Meyerhold and Bulgakov’s stories demonstrate the type of discourse that existed between intellectuals and power – a discourse that permeated the Russian-speaking art and culture at the time.

“LA CRUDELTÁ NON FA PER ME” - Pasolini, Artaud e il teatro del “quasi”
Creators: name: Acca, Fabio
Publisher: name: Antropologia e Teatro. Rivista di Studi
Year: 2012

description: Abstract – IT Artaud e il suo “teatro della crudeltà” costituiscono il paradigma attraverso il quale comprendere l’estromissione dell’idea di teatro di Pasolini dal sistema storiografico del Nuovo Teatro. Se oggi il teatro di Pasolini si candida ad essere il lascito più importante della drammaturgia italiana del ’900 al secolo successivo, questa conquista è stata possibile a fronte di una lunga, volontaria rimozione da parte della società del teatro. Per comprendere le cause di questo esilio è particolarmente efficace ritornare proprio alla sua esplicita distanza da Artaud. Il grande francese è stato, infatti, per la ricerca teatrale italiana, l’elemento chiave per una propria autopercezione e per una esposizione di identità. Ciò che è dunque importante mettere a fuoco non è tanto il rapporto diretto tra l’opera di Artaud e Pasolini, quanto piuttosto ciò che Pasolini connette al termine “crudeltà”, che tipo di teatro egli associa a questa parola, quale linguaggio della scena e dell’attore. Abstract – FR Artaud et son «théâtre de la cruauté » forment le paradigme par lequel on comprend l'exclusion de l'idée de théâtre de Pasolini par le système historiographique du Nouveau Théâtre. Si aujourd'hui l'oeuvre théâtrale de l'auteur pose sa candidature en tant qu'héritage le plus important de la dramaturgie italienne du XX siècle au succédant, cette conquête a été possible à travers un long et volontaire refoulement par la société du théâtre. Pour mieux comprendre les causes de cet exile, une perspective efficace est celle de revenir à son explicite écart à Artaud. Le grand français, en fait, a été l'élément-clé, pour la recherche théâtrale italienne, à remporter une perception de soi et à exposer sa propre identité. Ce qui est important à éclaircir n'est pas le rapport direct entre l'oeuvre d'Artaud et de Pasolini, mais plutôt ce que Pasolini joint au mot « cruauté », quelle sorte de théâtre il y inscrit, enfin quel langage de la scène et de l'acteur. Abstract – EN Artaud and his « theatre of cruelty » form the paradigm by which we understand the exclusion of Pasolini's theatre from the New Theatre historiographic system. The chance, for Pasolini's theatre, to propose itself as the most important inheritance of Italian dramaturgy of the XX century to the present one, has been possible throughout a long, intentional removal by the theatrical cultural milieu. To understand the reasons concerning this exile, an effective perspective implies beginning from its explicit distance from Artaud. The great French author, in fact, represented the key for Italian theatrical research, in order to perceive itself and to lay its identity out. The important matter to display it is not quite the direct relation between Artaud's and Pasolini's work, but rather what the Italian author connects to the word « cruelty », which kind of theatre, which language for the stage and the actor he associates to it.

description: Doping in sports continues to pose a significant challenge, tarnishing the integrity and fairness of athletic competitions. As athletes strive for excellence, the temptation to gain a competitive edge through prohibited substances or methods persists. To combat this issue, stringent measures and innovative strategies are imperative to maintain a level playing field and safeguard the spirit of fair play in sports. This article discusses some of the challenges involved in ensuring doping control in professional sports, including the methods used to establish doping control and the testing procedure, as well as worldwide coordination and collaboration to strengthen international relationships in doping control.
Che cos’è l’antiziganismo?

description: Abstract – IT Chi è zingaro? Colui che chiamo zingaro, che assegno a questa identità e che costituisco come "altro" dal resto della società. In questo senso, la storia degli zingari si confonde con quella dell'"antiziganismo", un neologismo che denota una pratica antica. Ma si può dire che la comparsa della nuova parola è legata agli odierni intrecci tra politiche multiculturali da un lato e politiche neoliberiste dall’altro? Abstract – FR Qui est Tsigane? Celui que je nomme Tsigane, que j'assigne à cette identité et que je constitue en "autre" du reste de la société. Dans ce sens, l'histoire des Tsiganes se confond avec celle de l'"antitsiganisme", un néologisme qui recouvre une pratique ancienne. Mais peut-on dire que l'apparition de ce nouveau mot est liée aux croisements actuels entre les politiques multiculturelles d'une part, et les politiques néolibérales de l'autre? Abstract – EN Who is Gypsy? The person I call Gypsy, to whom I assign this identity, is that I establish as "other" than the rest of society. In this sense, the history of Gypsies merges with that of "antigypsism", a neologism that denotes an ancient practice. But can it be said that the appearance of this new word is linked to the current entanglement between multi-cultural politics on one side and neo-liberalist politics on the other?

description: Given a spanning forest on a large square lattice, we consider by combinatorial methods a correlation function of $k$ paths ($k$ is odd) along branches of trees or, equivalently, $k$ loop--erased random walks. Starting and ending points of the paths are grouped in a fashion a $k$--leg watermelon. For large distance $r$ between groups of starting and ending points, the ratio of the number of watermelon configurations to the total number of spanning trees behaves as $r^{-ν} \log r$ with $ν= (k^2-1)/2$. Considering the spanning forest stretched along the meridian of this watermelon, we see that the two--dimensional $k$--leg loop--erased watermelon exponent $ν$ is converting into the scaling exponent for the reunion probability (at a given point) of $k$ (1+1)--dimensional vicious walkers, $\tildeν = k^2/2$. Also, we express the conjectures about the possible relation to integrable systems.

La dottrina degli avatara come prova per la datazione dell’Abhinayadarpana di Nandikesvara
Creators: name: Chierichetti, Pietro

Year: 2012

description: Abstract - IT Come per molte opere della letteratura indiana in sanscrito, anche per l’Abhinayadarpana di Nandikesvara è difficile proporre una datazione attendibile: nel suo contributo, l’autore cerca di utilizzare un elemento interno al testo per ipotizzare il periodo nel quale il testo potrebbe collocarsi. La citazione degli avatara di Visnu, esemplifacata attraverso una serie di gesti delle mani, viene vagliata criticamente al fine di un suo possibile utilizzo per collocare l’opera dal punto di vista cronologico. L’Abhinayadarpana, uno dei test fondamentali del teatro-danza in India, viene in questo modo inserito nel panorama più ampio della vicenda religiosa dell’India antica e la storia della religione hindu fornisce a sua volta uno strumento interessante per la ricostruzione della storia del testo. Abstract - EN As it often happens for many works of the Indian literature in Sanskrit, it is difficult to determine a possible dating of Nandikesvara’s iAbhinayadarpana: iin his artcle, the author tries to assume an inner element of the text for a hypothesis about the period in which the work could be dated back to. The Visnu’s avataras, quoted in the text through a series of hand gestures, are scientifcally examined to define the work from a chronological point of view. The Abhinayadarpana, one of the most important texts of the Indian Dance-Theatre, is put in the broader landscape of the Indian ancient religion and the hindu religion history becomes an interesting tool through which the text’s history is reconstructed.

Near and Far Transfer of Working Memory Training Related Gains in Healthy Adults

description: Enhancing intelligence through working memory training is an attractive concept, particularly for middle-aged adults. However, investigations of working memory training benefits are limited to younger or older adults, and results are inconsistent. This study investigates working memory training in middle age-range adults. Fifty healthy adults, aged 30-60, completed measures of working memory, processing speed, and fluid intelligence before and after a 5-week web-based working memory (experimental) or processing speed (active control) training program. Baseline intelligence and personality were measured as potential individual characteristics associated with change. Improved performance on working memory and processing speed tasks were experienced by both groups; however, only the working memory training group improved in fluid intelligence. Agreeableness emerged as a personality factor associated with working memory training related change. Albeit limited by power, findings suggest that dual n-back working memory training not only enhances working memory but also fluid intelligence in middle-aged healthy adults.
Faint Extended OH Emission from the Local Interstellar Medium in the Direction l \approx 108\circ, b \approx 5\circ

description: We have mapped faint 1667 OH line emission (TA \approx 20 - 40 mK in our \approx 30' beam) along many lines of sight in the Galaxy covering an area of \approx 4\circ \times 4\circ in the general direction of l \approx 108\circ, b \approx 5\circ. The OH emission is widespread, similar in extent to the local HI (r = 2 kpc) both in space and in velocity. The OH profile amplitudes show a good general correlation with those of HI in spectral channels of \approx 1 km/s; this relation is described by TA(OH) \approx 1.50 \times 10^{-4} TB(HI) for values of TB(HI) \approx 60 - 70 K. Beyond this the HI line appears to "saturate", and few values are recorded above \approx 90 K. However, the OH brightness continues to rise, by a further factor \approx 3. The OH velocity profiles show multiple features with widths typically 2 - 3 km/s, but less than 10% of these features are associated with CO(1-0) emission in existing surveys of the area smoothed to comparable resolution.
