Abstract:
ABSTRACT The Salmonella enterica serotype Typhimurium genome contains 13 operons with homology to fimbrial gene sequences. Here we investigated the role of 11 serotype Typhimurium fimbrial proteins, including FimA, AgfA (CsgA), BcfA, StbA, SthA, LpfA, PefA, StdA, StcA, StiA, and StfA, as antigens during the infection of genetically resistant mice (CBA). Upon the growth of serotype Typhimurium in standard laboratory broth culture, only the expression of FimA could be detected by Western blot analysis. The infection of mice with serotype Typhimurium grown in broth culture, followed by at least one subsequent infection, resulted in seroconversion of animals to FimA, AgfA, BcfA, StbA, SthA, LpfA, PefA, StdA, StcA, StiA, and StfA positivity. Most animals seroconverted to only a subset of these fimbrial antigens. The immunization of mice with glutathione S-transferase (GST)-FimA, GST-AgfA, GST-BcfA, GST-StbA, GST-SthA, GST-LpfA, GST-PefA, GST-StdA, GST-StcA, GST-StiA, and GST-StfA fusion proteins resulted in reduced fecal shedding of serotype Typhimurium during a challenge compared to that by a control group immunized with purified GST protein. Collectively, these data suggest that the expression of serotype Typhimurium fimbrial antigens is induced during the infection of mice.

Abstract:
ABSTRACT Sterigmatocystin (ST) and aflatoxin B1(AFB1) are two polyketide-derived Aspergillusmycotoxins synthesized by functionally identical sets of enzymes. ST, the compound produced by Aspergillus nidulans, is a late intermediate in the AFB1 pathway of A. parasiticus and A. flavus. Previous biochemical studies predicted that five oxygenase steps are required for the formation of ST. A 60-kb ST gene cluster in A. nidulanscontains five genes, stcB, stcF,stcL, stcS, and stcW, encoding putative monooxygenase activities. Prior research showed thatstcL and stcS mutants accumulated versicolorins B and A, respectively. We now show that strains disrupted atstcF, encoding a P-450 monooxygenase similar to A. parasiticus avnA, accumulate averantin. Disruption of either StcB (a putative P-450 monooxygenase) or StcW (a putative flavin-requiring monooxygenase) led to the accumulation of averufin as determined by radiolabeled feeding and extraction studies.

Abstract:
Stanniocalcin (STC) is a calcium- and phosphate-regulating hormone produced in bony fish by the corpuscles of Stannius, which are located close to the kidney. It is a major antihypercalcemic hormone in fish. As the corpuscles of Stannius are absent, and antihypercalcemic hormones are basically not necessary, in mammals, the discovery of a mammalian homolog, STC1, was surprising and intriguing. STC1 displays a relatively high amino acid sequence identity (∼50%) with fish STC. In contrast to fish STC, STC1 is expressed in many tissues, including kidney. More recently, a human gene encoding the second stanniocalcin-like protein, STC2, was identified. STC2 has a lower identity (∼35%) with STC1 and fish STC. Similar to STC1, STC2 is also expressed in a variety of tissues. Research into the functions of STCs in mammals is still at an early stage, and the ultimate physiological and pathological roles of STCs have not yet been established. A few studies indicate that STC1, similar to fish STC, stimulates phosphate absorption in the kidney and intestine, but the function of STC2 is still unknown. However, several interesting findings have been reported on their cellular localization, gene structure, and expression in different physiological and pathological conditions, which will be clues in elucidating the functions of STCs in mammals. STC1 expression is enhanced by hypertonicity in a kidney cell line or by ischemic injuries and neural differentiation in the brain. STC1 expression in the ovary is also enhanced during pregnancy and lactation. Calcitriol upregulates STC1 and downregulates STC2 expression in the kidney. Interestingly, STC1 and STC2 are expressed in many tumor cell lines, and the expression of STC2 is enhanced by estradiol in breast cancer cells. STC2 is also expressed in pancreatic islets. These results suggest that the biological repertoires of STCs in mammals will be considerably larger than in fish and may not be limited to mineral metabolism. This brief review describes recent progress in mammalian STC research.

Abstract:
Context Women with autoimmune Addison’s disease with normal ovulatory cycles but positive for steroid cell antibodies (StCA) have been considered at risk of premature ovarian insufficiency (POI). Design Thirty-three women younger than 40 years, with subclinical-clinical autoimmune Addison’s disease but with normally ovulatory menses, were followed up for 10 years to evaluate the long-term time-related variations of StCA, ovarian function and follicular reserve. All patients and 27 control women were investigated at the start and every year for the presence and titre of StCA (by indirect immunofluorescence), serum concentrations of anti-Mullerian hormone (AMH) and ovarian function at four consecutive menses every year. Results At the start of the study StCA were present in 16 women (group 1), at low/middle titres (≤1:32) in seven of them (43.8%, group 1A), at high titres (>1:32) in the remaining nine patients (group 1B, 56.2%), while they were absent from 17 patients (group 2). During the follow-up period, all women in group 1A remained StCA-positive at low/middle titres with normal ovulatory menses and normal gonadotrophin and AMH levels, while all patients in group 1B showed a further increase of StCA titres (1:128–1:256) and progressed through three stages of ovarian function. None of the patients in group 2 and controls showed the appearance of StCA or ovarian dysfunction during the follow-up. Conclusions The presence of StCA at high titres can be considered a good predictive marker of subsequent development of autoimmune POI. To single out the stages of autoimmune POI may allow a timely therapeutic choice in the subclinical and early clinical stages.

Abstract:
Based on the two-lane, symmetric traffic model (STCA), a modified traffic model, including Vehicle-to-Infrastructure (V2I) communication (STCA V2I model, for short), is presented. The combined full-autonomous and semi-autonomous vehicles are able to exchange information as well as the intentions of the driver with the surrounding vehicles through V2I communication. In the analyzed case, the communication between vehicles includes the sending of information to vehicles to the rear about the traffic situation ahead. Numerical simulations present a greater dispersion of vehicles with the same traffic density and fewer lane changes, while maintaining the same average vehicle speed as in the STCA model. Spatial–temporal profiles of traffic flow indicate that vehicles moving in accordance with the STCA V2I model are not subject to unnecessary concentration. Numerical studies have shown the positive and negative effects of transmitting traffic congestion messages.

Abstract:
The focus here is on the performance of and interaction between the Traffic Alert and Collision Avoidance System (TCAS) and the controller's short-term conflict alert (STCA) system. The data source used is UK Airprox Board Reports of close encounters between aircraft, and the focus is on commercial air transport aircraft using UK controlled airspace with a radar service. Do the systems work well together? Are controllers surprised when they find out that a pilot has received a TCAS resolution advisory? What do TCAS and STCA events say about collision risk? Generally, the systems seem to work together well. On most occasions, controllers are not surprised by TCAS advisories: either they have detected the problem themselves or STCA has alerted them to it. The statistically expected rate of future mid-air collisions is estimated by extrapolation of Airprox closest encounter distances.

Abstract:
The effects of neutralizer species on the transparency of injection-molded plates were studied using isotactic polypropylene (PP) containing a crystal nucleating agent—i.e., 1,3:2,4-bis-o-(4-methylbenzylidene)-d-sorbitol (MDBS). A plate containing lithium stearate (StLi) was more transparent than one containing calcium stearate (StCa) when the MDBS content was 0.1 wt. %. The addition of StLi accelerated the formation of MDBS fibers and the crystallization of PP. However, when the MDBS content was 1.0 wt. %, StCa improved the transparency more effectively than StLi. These results indicate that the combination of an appropriate amount of MDBS and the correct neutralizer species is critical for enhancing the transparency of injection-molded PP plates.

Abstract:
Design The design of the study was to investigate the prevalence of the following: 1) premature ovarian failure (POF) in patients with autoimmune Addison's disease (AD); 2) steroidproducing cells (StCA) and steroidogenic enzymes (17α-hydroxylase autoantibodies and P450 side-chain cleavage enzyme autoantibodies) in patients with or without POF; and 3) the value of these autoantibodies to predict POF. Patients The study included 258 women: 163 with autoimmune polyendocrine syndrome type 2 (APS-2), 49 with APS-1, 18 with APS-4, and 28 with isolated AD. Methods StCA were measured by an immunofluorescence technique and 17α-hydroxylase autoantibodies and P450 sidechain cleavage enzyme autoantibodies by immunoprecipitation assays. Results Fifty-two of 258 women with AD (20.2%) had POF. POF was diagnosed in 20 of 49 (40.8%) with APS-1, six of 18 (33.3%) with APS-4, 26 of 163 (16%) with APS-2, and none of 28 with isolated AD. In patients with APS-1 and APS-4, POF developed after AD, whereas it preceded AD in patients with APS-2. StCA were detected in 31 of 43 with POF (72%) and 51 of 198 without POF (25.7%). StCA were present in 22 of 38 with APS-1 (57.9%) (11 of 13 with POF); in five of 13 with APS-4 (38.5%) (three of four with POF); in 53 of 162 with APS-2 (32.7%) (17 of 26 with POF), and in one of 28 isolated AD patients (3.6%). Twelve of 13 patients with POF with a duration less than 5 yr (92.3%) and 18 of 25 with duration longer than 5 yr (72%) were StCA positive. Twenty-eight of 31 with POF (90.3%) were positive for at least one steroidogenic antibody. Forty-one women with AD less than 40 yr were followed up for a mean period of 9 yr. Eight of 21 women (38%) positive or seroconverted for steroidogenic autoantibodies developed POF at a mean age of 23 yr (six with APS-1, one with APS-2, and one with APS-4), and none of the 20 patients negative for steroidogenic autoantibodies developed POF. Conclusions This study indicates that AD is frequently associated with POF and that steroidogenic antibodies are markers of patients with POF. Steroidogenic autoantibodies are predictive markers of POF in patients with AD.

Abstract:
Based on the STCA model, an improved two-lane traffic CA model in view of turn signals is proposed. The model considers changes in driver behavior before and after the signaling of the leading vehicle, and introduces rules of changing lanes, cutting lanes and yielding the right of way for the flowing vehicle. Through computer numerical simulations, this study has presented time-space diagrams and also analyzed the effects of driver behavior of the rear vehicles on traffic flow. The results reveal that a higher rate of cutting lanes incurs a heavier traffic flow in normal situations while yielding the right of way relieves traffic congestion in a bottleneck situation. Compared with the traditional model, STCA model can depict more complex traffic situations resulted from different driver behaviors and reproduce a more realistic process of traffic flow.

Based on the STCA model, an improved two-lane traffic CA model considering turn signals is proposed. The model designs driver behavior changes because of the effect of turn light of front vehicle,and introduces rules of changing lanes, cutting lanes and yielding the right of way for the rear vehicle. Through computer numerical simulations, this study has presented curve diagrams of relationship between turning rate and energy consumption and also analyzed the effects of driver behavior of the rear vehicles on traffic flow. The results indicate that increased probability of lane change make more turning rate and energy consumption. When probability of lane change is from 0.5 to 1.0, turning rate increases 13.23% and energy consumption increases 22.15% . Compared with the traditional model, STCA model can depict more complex traffic situations and reproduce driver behaviors and more realistic process of traffic.

Abstract:

The purpose of this Master’s Thesis is to produce a specification for the aircraft conflict alert system STCA, and implement a prototype as a module in the air traffic surveillance system NOVA9000.

The specification is constructed based on functional requirements from EUROCONTROL and describes a system using a nominal trajectory method, where the future paths of aircraft are estimated. The trajectory is created using a probabilistic approach, where future positions are described with probability fields.

The prototype is implemented using the specification with some simplifications. The prototype is evaluated using recorded traffic from a heavy air traffic region surrounding an airport with parallel runways. 15 alerts were induced in 1,5 hour of morning traffic; this is far too much to be acceptable. Improvements are proposed and explanations to the high rate of alerts are made.

Abstract:
Short Term Conflict Alert (STCA) is an automated warning system designed to alert air traffic controllers to possible loss of separation between aircraft. STCA systems are complex, with many parameters that must be adjusted to achieve best performance. Current procedure is to manually ‘tune’ the governing parameters in order to finely balance the trade-off between wanted alerts and nuisance alerts. We present an incremental approach to automatically optimising STCA systems, using a simple evolutionary algorithm. By dividing the parameter space into regional subsets, we investigate methods of reducing the number of evaluations required to generate the Pareto optimal Receiver Operating Characteristic (ROC) curve. Multi-archive techniques are devised and are shown to cut the necessary number of iterations by half. A method of estimating the fitness of recombined regional parameter subsets without actual evaluation on the STCA system is presented, however, convergence is shown to be severely stunted when relatively weak sources of noise are present. We describe a method of aggressively perturbing parameters outside of their known ‘safe’ ranges when complex inhibitory interactions are present that prevent an exhaustive search of permitted values. The scheme prevents the optimiser from repeating ‘mistakes’ and unnecessarily wasting evaluations. Results show that a more complete picture of the Pareto-optimal ROC curve may be obtained without increasing the number of necessary iterations. Efficacy of the new methods is discussed, with suggestions for improving efficiency. Sources of parameter interdependence and noise are explored and where possible mitigating techniques and procedures suggested. Classifier performance on training and test data is investigated and potential solutions for reducing overfitting are evaluated on a toy problem. We comment on potential uses of the ROC in characterising STCA performance, for comparison to other systems and airspaces. Many industrial systems are structured in a similar way to STCA, we hope that techniques presented will be applicable to other highly parametrised, expensive problem domains.

The present study aimed to investigate the Literacy Estat?tics and Probabilistic for students entering and graduating from high school in two public schools in a city in the metropolitan region of Porto Alegre, RS. It tried to identify and analyze the abilities and competences in Literacy in the Information Treatment and Uncertainty. The research involved 21 groups, being nine of one city border school and 12 of the city central area. The researched universe involved 444 pupils. The data were collected through a questionnaire formed by informative questions to know general identification with the purpose to find Literacy. The research included a big bibliographic review and diferent theoretic perspectives. It was based, yet, in legal documents, mainly National Curriculum Parameters (PCN). The used methodology was that of the combined methods, based in Creswell (2010). The quantitative analysis was made in a descriptive way, showing results by charts and tables. The qualitative analysis employed the methodology of Textual Discourse (MORAES; GALIAZZI, 2011). The results indicate that the high school incoming and outgoing pupils showed limited abilities in charts and tables data writing, reading, calculation and interpretation. Thus, the pupils development was not satisfactory, considering Literacia as abilities and competences employment. Third degree pupils had better results than that of the first ones, but with similar difficulties in Treatment Information and Uncertainty. The shown abilities and competences in each degree, associated to those linked to this knowledge phase show the loss of learning in this area on the high school conclusion.

Traditional hazard analysis techniques based on failure models of accident causality, such as the probabilistic risk assessment (PRA) method currently used at NASA, are inadequate for analyzing safety at the system level. System-Theoretic Accident Model and Processes (STAMP) shifts the focus of safety from preventing failures to that of a dynamic feedback control system that enforces behavioral constraints. System-Theoretic Process Analysis (STPA), the hazard analysis method based on STAMP, was applied to the launch and mission phases of a NASA/JAXA Global Precipitation Measurement (GPM) Core Observatory-based satellite. Exploiting the fact that nearly all satellites follow similar lifecycles and employ common functional architectures with relatively-decoupled, unique mission payloads, a template for future satellite STPA safety analyses was developed. The template seeks to aid and guide new STPA applications while reducing analysis time by providing the STPA analysis for many common satellite functions. Increasing pressure to reduce satellite mission costs has renewed interest in modular payloads. Traditional hazard analysis methods are dependent on the hardware used, so they must be redone for the entire system if the payload is changed. This repetition of work is time intensive and costly. STPA is the only hazard analysis method that may be performed early in development and without details of the system hardware implementation. Using the GPM-based satellite STPA analysis, the influence of the mission payload on safety at the system-level is considered. Five types of control action mismatch resulting from changing payloads were identified along with the corresponding additional STPA analysis required to ensure safety at the system level.

Under hösten 1997 och våren/hösten1998 har ett pilotprojekt bedrivits i Linköpings kommun. Det är drivet av Kungliga Vetenskapsakademien och Kungliga Ingenjörsakademien och handlar om ett amerikanskt undervisningsmaterial inom naturvetenskap och teknik. På engelska heter det"Science and Technology for Children"vilket givit namnet STC. Det är ett temaarbete med 24 olika teman att använda under de 6 första skolåren.

För att använda materialet i skolan har vissa utvalda delar översatts till svenska. Det är endast en direktöversättning och inget speciellt anpassat till den svenska skolan. Detta arbete har jag gjort för att undersöka hur det går att använda STC materialet Motion and Design enligt våra svenska styrdokument. Jag har även tittat på varför lärare fastnar för det.

Resultatet visar att det fungerar relativt bra utifrån de förutsättningar materialet hade när det provades. I framtiden kan vissa förändringar ske utifrån utvärderingar och respons från lärare. Materialet är väldigt tilltalande enligt konceptet att allt kommer i en låda och är förberett.

Developmental product testing currently evaluates system safety the same way it evaluates system performance: it attempts to isolate individual components' behaviors to evaluate their reliability. However, today's systems are often irreducible because of their complexity, leaving current practices ineffective at identifying safety deficiencies. Evolving to a modern systems-based hazard analysis is important for product development. Products stand to benefit during the testing stage, before initial fielding. In test, designs meet operation for the first time, and use practices and organizational influences both contribute to the safety of the system. By evaluating safety as an emergent property, hazards that emerge because of the testing process itself can be mitigated, and hazards that exist because of the inherent system design and use philosophy can be identified and traced throughout development and fielding. System-Theoretic Process Analysis (STPA), developed by Nancy Leveson at the Massachusetts Institute of Technology, is a modern hazard analysis technique that identifies unsafe scenarios in a system in order to generate requirements to eliminate or control those scenarios. It improves on traditional reductionist approaches that treat accident causation only as a linear chain of events or probabilistic occurrence of simultaneous component failures (including human error). While systems-based and complete, STPA could benefit from additional guidance, particularly in the identification of human contributions to accidents. The present research begins by extending STPA to include more guidance for the controller analysis, including refinements to the process model, fundamental human-engineering considerations, and socio-organizational influences. Next, Leveson's organizational control structure example is updated to include a test stage that serves as an intermediary between design and field use. Model inclusion criteria are updated, and Explicit-Influence Maps are introduced as a tool to understand the organization and aid in hazard analysis. Finally, this research investigates the U.S. Air Force developmental testing enterprise and applies STPA to a product test. Results are compared to that of the test-safety planning and reporting techniques traditionally in use, and utility is assessed with a research survey administered to developmental test professionals.

Cities, living spaces and inhabited by individuals, are constituted as the materialization of the processes and social and spatial relationships, and so permanently is changing. The urban order arises from the relationship between the right and the cities, aiming to make them better, fairer and more democratic for the entire community. Damage to urban order reach diffuse and collective interests, so should be avoided and combated. This study aims to understand the damage from the analysis how and under what conditions the damage occurs urban order in the city of Salvador. The data used were the civil investigations, that calculate the offense or violation of urban order in the city of Salvador, and the Public Civil Actions that aim to blame, repair and contain or reverse the damage caused to this order, both initiated by the Prosecutor's Office of housing and Bahia prosecutors Urbanism, from 2008 to 2014. the results show that the protection of urban order has not been effective, given the large amount and complexity of the damage to the urban order. Such damage has been generated by actions motivated by private interests or by omission and failures of public administration, and materialize, spatially in different ways.
As cidades, espa?os habit?veis e habitados pelos indiv?duos, se constituem como a materializa??o dos processos e das rela??es sociais e espaciais, e por isso, permanentemente, est? em transforma??o. A ordem urban?stica surge da rela??o entre o direito e as cidades, visando torn?-las, melhores, mais justas e mais democr?ticas para toda a coletividade. Os danos ? ordem urban?stica atingem interesses difusos e coletivos, por isso devem ser evitados e combatidos. Assim, este estudo visa compreender o dano, a partir da an?lise de como e em quais condi??es ocorre o dano ? ordem urban?stica no munic?pio do Salvador. Os dados utilizados foram os Inqu?ritos Civis, que apuram a ofensa ou viola??o ? ordem urban?stica no Munic?pio do Salvador, e as A??es Civis P?blicas que visam responsabilizar, reparar e conter ou reverter os danos gerados a esta ordem, ambos instaurados pela Promotoria de Justi?a de Habita??o e Urbanismo do Minist?rio P?blico da Bahia, no per?odo de 2008 a 2014. Os resultados encontrados demonstram que a tutela da ordem urban?stica n?o tem sido efetiva, dada a grande quantidade e complexidade dos danos ? ordem urban?stica. Tais danos t?m sido gerados por a??es motivadas pelos interesses privados ou por omiss?o e falhas da gest?o p?blica, e se materializam, espacialmente, de formas distintas.

Abstract:
The temporal credit assignment problem, which aims to discover the predictive features hidden in distracting background streams with delayed feedback, remains a core challenge in biological and machine learning. To address this issue, we propose a novel spatio-temporal credit assignment algorithm called STCA for training deep spiking neural networks (DSNNs). We present a new spatiotemporal error backpropagation policy by defining a temporal based loss function, which is able to credit the network losses to spatial and temporal domains simultaneously. Experimental results on MNIST dataset and a music dataset (MedleyDB) demonstrate that STCA can achieve comparable performance with other state-of-the-art algorithms with simpler architectures. Furthermore, STCA successfully discovers predictive sensory features and shows the highest performance in the unsegmented sensory event detection tasks.
