Robust Semantic Parsing with Adversarial Learning for Domain Generalization

International audienceThis paper addresses the issue of generalization for Semantic Parsing in an adversarial framework. Building models that are more robust to inter-document variability is crucial for the integration of Semantic Parsing technologies in real applications. The underlying question throughout this study is whether adversarial learning can be used to train models on a higher level of abstraction in order to increase their robustness to lexical and stylistic variations.We propose to perform Semantic Parsing with a domain classification adversarial task without explicit knowledge of the domain. The strategy is first evaluated on a French corpus of encyclopedic documents, annotated with FrameNet, in an information retrieval perspective, then on PropBank Semantic Role Labeling task on the CoNLL-2005 benchmark. We show that adversarial learning increases all models generalization capabilities both on in and out-of-domain data

Комбінаційне розсіяння світла в локально-ангармонічних кристалічних системах з сильними електронними кореляціями: квантово-статистичний підхід

In a way to explore the different ways a computer may discern information from its surroundings this is a thesis focusing on analysis of a live camera feed. The core is how to build a turret, a tower with rotating axes, using a single-card computer and a camera module and make it interact based on visual input. The interaction explored is to track an object in the live feed. The tracking is solved by using Python 2 with OpenCV’s color-filter and contour-finder to create color tracking used to find a predefined object and determine the vector which the turret will aim towards. The turret is mounted on a motor-controlled chassis for increased mobility. Additional research is made on the turret’s control system to find the most efficient and still reliable one if cycleskips of calculations are introduced for performance saving. Herein is a full construction of said turret and extended explanation of relevant theory. The final product is able to follow a pre-specified object with a distinct and homogenous color, with dependable certainty and is able to take user-defined actions based on the information. Cycleskips to increase performance is determined, through statistical experiments, not to be an efficient method.I syfte att utforska olika sätt som en dator kan urskilja information från sin omgivning är detta ett projekt med fokus på analys av ett direkt kameraflöde. Grunden i projektet är hur man bygger ett kanontorn med roterande axlar med hjälp av en enkortsdator och kameramodul för att se till att systemet agerar baserat på visuell information. Det specifika interagerandet som utforskas är att spåra och följa ett objekt i kameraflödet. Spårningen löses med hjälp av Python 2 med OpenCVs färgfilter och konturfinnare för att tillsammans skapa färgsökning som används för att hitta ett fördefinierat föremål och bestämma vektorn som kanontornet kommer att sikta mot. Kanontornet är monterat påett motorstyrt chassi för ökad mobilitet. Utökad forskning görs på kanontornets styrsystem för att hitta det mest effektiva och fortfarande tillförlitliga styrsystem om cykelskippning införs över alla beräkningar för sparande av prestanda. Häri är en fullständig konstruktion av nämnda kanontorn och djupgående förklaring av relevant teori. Slutprodukten kan följa ett förbestämt objekt med en distinkt och homogen färg, med pålitlig säkerhet och klarar av att ta användardefinierade handlingar grundade på den givna informationen. Cykelskippning för att spara prestanda bevisas genom statistiska tester inte vara en effektiv metod

The Leadership Processes of Pacific Public Servants in Aotearoa, New Zealand

This dissertation presents research focused on leadership processes among Pacific public servants at multiple levels in the New Zealand Public Service. The current study was guided by this research question: What are the leadership processes currently employed by Pacific public servants in the New Zealand Public Service? This study also explored participants' views on the effect of Pacific cultural backgrounds and organisational contexts on their current experience of leadership processes. The exploration of the topic was developed within a post-positivist research paradigm, using phenomenological methodology to examine the leadership processes of Pacific public servants. It employs qualitative case studies of two New Zealand Public Service organisations in the Wellington region. I employed two data collection tools in these case studies. The first was the use of in-depth interviews, and the second was an analysis of relevant organisational documents. A total of sixteen Pacific public servants participated in my study, eight from each case organisation. The findings indicated that the Pacific participants understood leadership as a social process of collective influence within a context. Participants perceived participating, networking and relationship building, learning about leadership from cultural contexts, and practising the Pacific value of va as important leadership processes for their performance in the organisations in which they were working. This study also found that the organisations' key roles and leadership values, which are embedded in Pacific cultures, shaped participants' experiences of the leadership processes. The findings also highlight some factors that contribute to and constrain the Pacific public servants' leadership processes. This emphasises the need for diverse policies to encompass leadership development. This study also highlights the need for leadership support for Pacific public servants at all levels in their New Zealand organisations. Practical and future research recommendations gained from the findings are discussed. The study contributes to the field of leadership research on Pacific public servants in New Zealand, and provides a different perspective on leadership processes in general leadership theory

Public International Law: Environmental Law

Noteworthy international activity relating to the environment occurred in a wide variety of fora in 2000. This chapter provides brief updates on some of the most significant developments. Though by no means a comprehensive review, the chapter reflects the wide sweep of issues and large number of entities now involved in the development of international environmental law, at the start of this new century. It also reflects how critical and complex this international work is, and how much remains to be done

Overactive bladder-18 years - Part II

Traditionally, the treatment of overactive bladder syndrome has been based on the use of oral medications with the purpose of reestablishing the detrusor stability. The recent better understanding of the urothelial physiology fostered conceptual changes, and the oral anticholinergics - pillars of the overactive bladder pharmacotherapy - started to be not only recognized for their properties of inhibiting the detrusor contractile activity, but also their action on the bladder afference, and therefore, on the reduction of the symptoms that constitute the syndrome. Beta-adrenergic agonists, which were recently added to the list of drugs for the treatment of overactive bladder, still wait for a definitive positioning - as either a second-line therapy or an adjuvant to oral anticholinergics. Conservative treatment failure, whether due to unsatisfactory results or the presence of adverse side effects, define it as refractory overactive bladder. In this context, the intravesical injection of botulinum toxin type A emerged as an effective option for the existing gap between the primary measures and more complex procedures such as bladder augmentation. Sacral neuromodulation, described three decades ago, had its indication reinforced in this overactive bladder era. Likewise, the electric stimulation of the tibial nerve is now a minimally invasive alternative to treat those with refractory overactive bladder. The results of the systematic literature review on the oral pharmacological treatment and the treatment of refractory overactive bladder gave rise to this second part of the review article Overactive Bladder - 18 years, prepared during the 1st Latin-American Consultation on Overactive Bladder.Univ Fed Sao Paulo, EPM, Sao Paulo, SP, BrazilUniv Sao Paulo, Dept Urol, BR-05508 Sao Paulo, SP, BrazilFac Med ABC, Dept Urol, Sao Paulo, SP, BrazilUniv Los Andes, Dept Urol, Bogota, ColombiaEscuela Med Mil, Dept Urol, Mexico City, DF, MexicoHosp Clin Jose San Martin, Catedra Urol, Buenos Aires, DF, ArgentinaMae de Deus Ctr Hosp, Dept Urol, Porto Alegre, RS, BrazilUniv Fed Ciencias Saude Porto Alegre, Porto Alegre, RS, BrazilAC Camargo Hosp, Dept Urol, Sao Paulo, SP, BrazilHosp Clinico Fuerza Area Chile, Santiago, ChileInst Mexicano Seguro Social, Mexico City, DF, MexicoHosp Souza Aguiar, Dept Urol, Rio De Janeiro, RJ, BrazilComplejo Med Policial Churruca Visca, Serv Urol, Buenos Aires, DF, ArgentinaCtr Policlin Valencia Vina, Valencia, VenezuelaHosp Pablo Tobon Uribe, Medellin, ColombiaClin Indisa, Serv Urol, Providencia, ChileCtr Reabilitacao & Readaptacao Dr Henriqe Santill, Goiania, Go, BrazilHosp Univ Caracas, Serv Urol, Caracas, VenezuelaUniv Fed Ceara, Div Urol, Fortaleza, Ceara, BrazilUniv Fed Sao Paulo, EPM, Sao Paulo, SP, BrazilWeb of Scienc

Overactive bladder-18 years - Part I

Overactive bladder syndrome is one of the lower urinary tract dysfunctions with the highest number of scientific publications over the past two decades. This shows the growing interest in better understanding this syndrome, which gathers symptoms of urinary urgency and increased daytime and nighttime voiding frequency, with or without urinary incontinence and results in a negative impact on the quality of life of approximately one out of six individuals - including both genders and almost all age groups. The possibility of establishing the diagnosis just from clinical data made patients' access to specialized care easier. Physiotherapy resources have been incorporated into the urological daily practice. A number of more selective antimuscarinic drugs with consequent lower adverse event rates were released. Recently, a new class of oral drugs, beta-adrenergic agonists has become part of the armamentarium for Overactive Bladder. Botulinum toxin injections in the bladder and sacral neuromodulation are routine modalities of treatment for refractory cases. During the 1st Latin-American Consultation on Overactive Bladder, a comprehensive review of the literature related to the evolution of the concept, epidemiology, diagnosis, and management was conducted. This text corresponds to the first part of the review Overactive Bladder 18-years.Univ Fed Sao Paulo, EPM, Rua Dr Oscar Monteiro Barros 617-141, BR-05641010 Sao Paulo, SP, BrazilUniv Sao Paulo, Dept Urol, BR-05508 Sao Paulo, SP, BrazilFac Med ABC, Dept Urol, Sao Paulo, SP, BrazilUniv Los Andes, Dept Urol, Bogota, ColombiaEscuela Med, Dept Urol, Mexico City, DF, MexicoHosp Clin Jose San Martin, Catedra Urol, Buenos Aires, DF, ArgentinaMae de Deus Ctr Hosp, Dept Urol, Porto Alegre, RS, BrazilUniv Fed Ciencias Saude Porto Alegre, Porto Alegre, RS, BrazilAC Camargo Hosp, Dept Urol, Sao Paulo, BrazilHosp Clin Fuerza Area Chile, Santiago, ChileInst Mexicano Seguro Social, Mexico City, DF, MexicoHosp Souza Aguiar, Dept Urol, Rio De Janeiro, RJ, BrazilComplejo Med Policial Churruca Visca, Serv Urol, Buenos Aires, DF, ArgentinaCtr Policlin Valencia Vina, Valencia, VenezuelaHosp Pablo Tobon Uribe, Medellin, ColombiaClin Indisa, Serv Urol, Providencia, ChileCtr Reabilitacao & Readaptacao Dr Henriqe Santill, Goiania, Go, BrazilHosp Univ Caracas, Serv Urol, Caracas, VenezuelaUniv Fed Ceara, Div Urol, Fortaleza, Ceara, BrazilUniv Fed Sao Paulo, EPM, Rua Dr Oscar Monteiro Barros 617-141, BR-05641010 Sao Paulo, SP, BrazilWeb of Scienc

The Essentials of Protein Import in the Degenerate Mitochondrion of Entamoeba histolytica

Several essential biochemical processes are situated in mitochondria. The metabolic transformation of mitochondria in distinct lineages of eukaryotes created proteomes ranging from thousands of proteins to what appear to be a much simpler scenario. In the case of Entamoeba histolytica, tiny mitochondria known as mitosomes have undergone extreme reduction. Only recently a single complete metabolic pathway of sulfate activation has been identified in these organelles. The E. histolytica mitosomes do not produce ATP needed for the sulfate activation pathway and for three molecular chaperones, Cpn60, Cpn10 and mtHsp70. The already characterized ADP/ATP carrier would thus be essential to provide cytosolic ATP for these processes, but how the equilibrium of inorganic phosphate could be maintained was unknown. Finally, how the mitosomal proteins are translocated to the mitosomes had remained unclear. We used a hidden Markov model (HMM) based search of the E. histolytica genome sequence to discover candidate (i) mitosomal phosphate carrier complementing the activity of the ADP/ATP carrier and (ii) membrane-located components of the protein import machinery that includes the outer membrane translocation channel Tom40 and membrane assembly protein Sam50. Using in vitro and in vivo systems we show that E. histolytica contains a minimalist set up of the core import components in order to accommodate a handful of mitosomal proteins. The anaerobic and parasitic lifestyle of E. histolytica has produced one of the simplest known mitochondrial compartments of all eukaryotes. Comparisons with mitochondria of another amoeba, Dictystelium discoideum, emphasize just how dramatic the reduction of the protein import apparatus was after the loss of archetypal mitochondrial functions in the mitosomes of E. histolytica
