Full textReal-time embedded systems, despite their limited resources, are evolving very quickly. For such systems, it is not enough to ensure that all jobs do not miss their deadlines, it is also mandatory to ensure the good quality of the data being transmitted from tasks to tasks. Speaking of the data quality constraints, they are expressed by the maintenance of a set of properties that a data sample must exhibit to be considered as relevant. It is mandatory to find trade-offs between the system scheduling constraints and those applied to the data. To ensure such properties, we consider the wait-free mechanism. The size of each communication buffer is based on the lifetime bound method. Access to the shared resources follows the single writer, many readers. To contain all the communication particularities brought by the uORB communication mechanism we modeled the interactions between the tasks by a bipartite graph that we called communication graph which is comprised of sets of so-called domain messages. To enhance the predictability of inter-task communication, we extend Liu and Layland model with the parameter communication state used to control writing/reading points.We considered two types of data constraints: data local constraints and data global constraints. To verify the data local constraints, we rely on the sub-sampling mechanism meant to verify data local constraints. Regarding the data global constraints, we introduced two new mechanism: the last reader tags mechanism and the scroll or overwrite mechanism. These 2 mechanisms are to some extent complementary. The first one works at the beginning of the spindle while the second one works at the end of the spindle

Full textToday, millions of purchased domain sites names are sitting unused with no real web designs or concrete purpose coupled with them. Why would not owners engage a web-hosting domain-parking hotel so they can earn money through eyeballs advertising or click revenue while their sites sits unused? Parking hotels claim access to passive domain monetization through advertising programs tailored to generate revenue via automatic web page generations containing tailored advertisement. When visitors access these web sites, revenue is generated for domain owners. This study sought to investigate if parking hotels’ advertising claim, that you can make money through them, carries substance. Hence, is it possible to generate sufficient revenue using a parking hotel’s advertising revenue model to pay for the cost of domain ownership and, if possible, generate excess revenue? The study’s epistemological approach, trying to distinguish the truth about the hotels’ claims, stems from a ontological discussion around web hosting hotels’ advertising vehicle existence and its ability to generates revenue. The study challenged a parking hotel’s claim through an inductive quantitative approach by watching advertising revenue for 59 domain names over 105 days. Quantitative data concluded, through a statistical approach, that there were insufficient advertising income, approximately a nickel, to cover the annual cost of approximately $6 USD. Therefore, the study concluded that the advertising claims were misleading and recommends that sites are not purchased, or renew, for the purpose of making money through web hotels’ advertising models.

Full textControl of gene expression is a crucial process for development, reproduction or acclimation to environmental stresses and involves post-transcriptional regulatory pathways acting on messenger RNAs (mRNAs). These molecules carry chemical modifications of which N6-methyladenosine (m6A) is one of the most abundant. This modification allows notably the recruitment of specific proteins qualified as “readers” which, in mammals, mostly act to promote decay and/or translation of mRNAs. My thesis aimed to characterize the functions of one of these readers, named ECT2, in the model plant Arabidopsis thaliana. First, its binding function to methylated mRNAs and its role in plant development was demonstrated. At the molecular level, a proteomic approach identified numerous ECT2’s protein partners, mainly involved in mRNA metabolism including translation inhibition factors. Results obtained from a translatome analysis suggest a model where ECT2 could play a repressive role on the translation of methylated mRNAs cooperatively with its partners LARP1 and DCP5, two evolutionarily conserved factors acting in translational control of mRNAs. Finally, I also discovered that ECT2 is dynamically modified with phosphorylations in response to heat stress affecting especially its ability to recognize m6A residues. These works suggests for the first time that the activity of an m6A reader could be regulated by phosphorylations in response to environmental changes

Full textInsights into the control of mRNA decay by YTH proteinsduring the transition from meiosis to mitosis in yeasts.Keywords: Epitranscriptomics, mRNA decay, meiosis, multi-protein complexes, YTH domainCell cycle is controlled by multi-layered processes. A gene is transcribed in mRNA which is translated in proteins but innumerable regulation processes are working to control every step of this apparently simple process. Among these regulatory check points, post-transcriptional regulation is an important one, where formation of a protein-RNA complex may direct the cellular fate. Among these RNA binding proteins, YTH domain proteins are most novel, discovered in late 90s. YTH domain proteins are abundant in eukaryotes and absent in prokaryotes. YTH domain proteins constitute the majority of reader proteins that can specifically identify m6A modification. Human beings have five YTH domain proteins YTHDF1-3, YTHDC1-2 (Hazra, D., Chapat, C., & Graille, M. (2019). m6A mRNA Destiny: Chained to the rhYTHm by the YTH-Containing Proteins. Genes, 10(1), 49.). Although it is evident that these proteins are controlling cellular fate, the function of each protein and their network is yet to be elucidated. In yeast, there is only one YTH domain protein present: Pho92 in Saccharomyces cerevisiae and Mmi1 in Schizosaccharomyces pombe. Apart from the YTH domain there is no sequence homology between these two proteins but their cellular function is similar.It is well established that Mmi1 is responsible for degradation of meiosis specific transcripts during vegetative growth of the cell. Mmi1 forms a tight complex with a small protein, Erh1 (Erh1-Mmi1 complex or EMC). EMC can physically interact with Not1 of CCR4-Not complex and recruit it for degradation of DSR (determinant of selective removal) containing RNAs. The action of Mmi1 is in turn regulated by an RRM domain protein, Mei2. During meiosis, Mei2, along with a lncRNA meiRNA sequesters Mmi1 in a nuclear dot, rendering it inactive and ensuring smooth continuance of meiosis. These three proteins, Mmi1-Erh1-Mei2 play a key role in mitosis to meiosis switch.In S. cerevisiae, Pho92 is involved in the degradation of PHO4 transcripts contributing to phosphate metabolism pathway, during phosphate starvation and also participates in the degradation of mRNAs containing the N6-methyladenosine (m6A) epitranscriptomics marks. Similarly, to S. pombe Mmi1, Pho92 recruits CCR4-Not complex by physical interaction with Not1.During my PhD, I have tried to elucidate the role of these two YTH domain proteins from two model organisms, S. cerevisiae and S. pombe, in mRNA degradation and cell cycle regulation using biochemical and structural approaches.Pho92 of S. cerevisiae physically interacts with Not1 of CCR4-Not complex, we were able to determine the boundaries of this interaction. The interaction between these two proteins was studied by Fluorescence anisotropy. The protein complex was successfully purified and crystallization trials are ongoing.From S. pombe, structure of Mei2-RRM3 was solved with and without an RNA. RNA binding properties of Mei2-RRM3 was studied by ITC. The structure of Erh1 was also solved and we tried to elucidate its importance for biological function of Mmi1. A co-crystallization trial was performed with Mmi1-Mei2-RNA but it was unsuccessful and we ended up with Mmi1 crystals

Full textThe ribosomal protein S1 is essential to the initiation of translation in gram-negative bacteria. S1 is also used, at their own profit, by several bacteriophages. In particular, it accelerates the reaction rate of the phage T4 ribonuclease RegB, which specifically inactivates some of the phage early messenger RNAs by cleaving them in the middle of the GGAG sequence found in their translation initiation region. We are interested in analyzing the way S1 accelerates RegB reaction. The laboratory already identified the region of S1, formed of three conserved domains, responsible for RegB acceleration. It also showed the lifetimes of RNA-S1 and RNA-RegB complexes are short and characterized their interaction surfaces. No complex between RegB and SI could be identified. In these conditions, we wondered whether the acceleration of RegB by SI is due to the formation of a ternary complex or whether it involves a catalytic action of SI on the RNAs. To answer this question, first we solved, by NMR, The structure of two S1 domains, the 6th and 4th. We choose the domain 4 for the central position in the RegB activating domain, and the 6th domain to create a relative close model for the other domains. Second, we created a new classification of S1 domains by bioinformatics analyses. Finally we start to study the interactions between RegB, SI and some oligoribonucleotides. By simply comparing 1H-15N HSQC and HNCO experiments recorded on RegB/RNA, Sl/RNA, RegB/Sl and RegB/Sl/RNA mixes, we characterize the formation of a ternary complex

Full textBig Data-arbetsflöden består av flera orkestreringssteg som utför olika dataanalysuppgifter. Dessa uppgifter bearbetar heterogena data med hjälp av olika databehandlings- och lagringsresurser. På grund av stora variationen av tillämpningsområden, den involverade tekniken, och komplexiteten hos datamängderna, kräver utformning och implementering av Big Data-arbetsflöden samarbete mellan domänexperter och tekniska experter. Befintliga verktyg är dock för tekniska och vilket försvårar för domänexperter att delta i processen att definiera och genomföra Big Data-arbetsflöden. Dessutom är majoriteten av befintliga verktyg utformade för specifika tillämpningar, som bioinformatik, beräkningskemi och genomik. Verktygen är också baserade på specifika teknikstackar som inte erbjuder flexibla metoder för att kunna underhålla och återanvända kod. Denna avhandling ämnar att presentera design och implementering av en Big Data-arbetsflödeslösning som utnyttjar ett domänspecifikt språk (DSL) för att dölja komplexa tekniska detaljer, vilket gör det möjligt för domänexperter att delta i processdefinitionen av arbetsflöden. Arbetsflödeslösningen använder en kombination av mjukvaruutrustningsteknik och meddelande-orienterad mellanvara (MOM) för att möjliggöra en mer skalbar körning av arbetsflöden. Tillämpningslösningen demonstreras genom att implementera en prototyp baserad på ett verkligt dataflöde. Efter en granskning av de genomförda testerna modifierades den föreslagna arbetsflödeslösningen för att uppnå en effektiv arbetsflödesdefinition och skalbar körning. Dessutom presenteras resultaten av en uppsättning experiment där man jämför skalbarheten för det föreslagna tillvägagångssättet med Argo Workflows, ett av de mest lovande verktygen inom Big Data-arbetsflöden

Full textAlphaviruses such as Chikungunya virus and Venezuelan equine encephalitis virus (VEEV) are (re-)emerging arboviruses. They own an unconventional mRNA capping catalysed by nsP1 and nsP2 leading to the formation of a cap-0 structure (m7GpppN-), which is crucial for virus replication and constitutes an attractive antiviral target. NsP1 catalyses three activities: methyltransferase (MTase), guanylylation (GT) and guanylyltransferase (GTase). A high throughput ELISA was developed to monitor the GT reaction and screen the Prestwick Chemical library®. The IC50 was determined for 18 selected hit compounds. Three series of compounds were selected for further characterization. These compounds poorly inhibit a cellular MTase suggesting their specificity against nsP1. Analogue search and structural activity relationships (SAR) were also initiated to identify the active pharmacophore features. The results show that our strategy is a convenient way to select specific hit compounds targeting the mRNA capping of alphaviruses. NsP3 consists in a Macro domain at the N-terminal, a zinc binding domain and a C-terminal hypervariable region. The Macro domain is essential for the replication through ADP-ribose (ADPr) binding and de-ribosylation of cellular proteins. In order to better understand this mechanism, we initiated a structure-based study of Getah virus (GETV) Macro domain, which contains a peculiar substitution in the catalytic loop. By crystallographic studies we characterized several poses adopted by ADPr in the binding site. Together, these poses may represent several snapshots of the ADP-ribosylhydrolase mechanism, highlighting new residues to be further characterised

Full textIn eukaryotes, poly (A) tails are added to nuclear pre-mRNA 3'-ends in the two steps of cleavage and polyadenylation. This co-transcriptional processing requires the activity of a large protein complex comprising at least 20 different polypeptides in yeast organized primarily into the two factors CF IA and CPF. We are interested in the functional characterization of Pcf11, a CF IA subunit. The Pcf11 protein is organized into seven different domains, but here is still a large portion of the polypeptide that has not yet been characterized. For example the region from the end of the CTD interaction domain (CID) to an uninterrupted stretch of 20 glutamine residues has no known function. Recently, the structure of this region, called the 2nd NTD have been characterized. To gain insight into the function of the 2nd NTD and the two zinc fingers motif surrounding the Clp1 interaction domain, we have employed a systematic strategy of mutagenesis, either by deletion or via point mutations. The 2nd NTD is a folded domain composed of three α-helices. The deletion of this domain induced a severe defect of growth in yeast and impaired transcription termination of snoRNAs. Despite its similarity in structure and function with the CID, the 2nd NTD seems to act like an independent RNA binding domain. We don’t know yet the real function of the two zinc fingers motif at the C-terminal region of Pcf11, but the mutation of Cystein residues into serine of one of the two motifs impaired cleavage and polyadenylation. The mutation of the first motif is less harmful than the mutation of the second motif. The simultaneous mutation is lethal in yeast

Compiler error messages should allow programmers to understand and solve quickly problems found during the compilation process. However, compilers usually issue short contextless messages with little information and with terms that are difficult to understand. This work introduces the plug-in Error Message System (EMS) that allows the presentation of easy-to-understand and more meaningful error messages. EMS is a plug-in to the Eclipse IDE. It is highly configurable through Domain Specific Languages (DSLs). The DSLs allow that regular users build their own error messages and share them. Beginner programmers can use a set of error messages adapted to them thus reducing the time of understanding and correction of compilation errors.
As mensagens de erro dos compiladores devem permitir que os programadores compreendam e solucionem os problemas encontrados durante o processo de compilação rapidamente. Entretanto, os compiladores usualmente emitem mensagens curtas, sem contexto, pouco informativas e com termos de difícil compreensão. Este trabalho apresenta o plug-in Error Message System (EMS) que permite a apresentação das mensagens de erro mais fáceis de entender e mais informativas. EMS é um plugin para a IDE Eclipe e é altamente configurável através de linguagens específicas de domínio(LED). As LEDs permitem que usuários comuns façam suas próprias mensagens de erro e as compartilhem. Programadores iniciantes podem utilizar um conjunto de mensagens adaptadas a eles, reduzindo o tempo de compreensão e correção dos erros de compilação.

Full textSetdb1 is a “histone” lysine methyltransferase (KMT) belonging to the SUV39 family that methylates lysine 9 of histone H3 (H3K9), one of the major epigenetic machineries mainly involved in gene repression. Notably, Setdb1 establishes mono-, di- and tri-methylation of H3K9. Setdb1, or Eset in mice, is essential for the survival, the pluripotency and the self-renewal of mouse embryonic stem cells (mESCs); Eset knockout is lethal at the peri-implantation stage at 3.5 dpc in mice. Setdb1 is also required for the differentiation of many progenitor cell types: spermatogenesis, neurogenesis, chondrocyte differentiation and skeletal muscle differentiation. Moreover, Setdb1 has been associated with several diseases: it is amplified in melanoma and lung cancer and it is dysregulated in liver, prostate, colorectal and breast cancers, Huntington disease and schizophrenia.Remarkably, beyond histones, Setdb1 methylates many non-histone substrates, such as UBF, p53, AKT, Tat and ING2 proteins. Although Setdb1 has been always associated with its nuclear role, it turns out that Setdb1 is the only H3K9 KMT to have also a cytoplasmic localization, in several cell types, including mESCs, mouse embryonic fibroblasts (MEFs) and HeLa cells. However, the function of Setdb1 in the cytoplasm remains totally unknown. To investigate Setdb1 cytoplasmic role, we have used mouse embryonic stem cells (mESCs), in which Setdb1 is essential. Our results show that cytoplasmic Setdb1 is crucial for the survival of mESCs: indeed, the number of apoptotic cells increases after the loss of cytoplasmic Setdb1. We found that cytoplasmic Setdb1 affects newly protein synthesis in mESCs. We further show that cytoplasmic Setdb1 interacts with mESCs-specific protein Trim71 (also called Lin41) and with the initiation translation factor eIF3c in mESCs. Finally, we reported that Setdb1 and Trim71 together co-regulate mRNA stability and translation. Our current data unravel the essential cytoplasmic function of Setdb1, for long time considered exclusively an “histone” lysine methyltransferase, and provide new insights into the post-transcriptional regulation of gene expression mediated by a fundamental epigenetic regulator

Extensively studied in computer science and education, distance learning not only allows students to acquire knowledge over the Internet through courses, but also provides a viable solution for individuals with no time for traditional classroom instruction. Distance learning allows individuals to learn without the constraints of time and location by using text, voice, video and data. However, in a real time distance learning system, learners and teachers interact with each other through questions and replies sent online. Conversely, a traditional distance learning system requires supervisors or teachers always available on online to facilitate and monitor a learner’s progress by answering questions and guiding users. Such a system is not only expensive, but requires constant supervision online. This dissertation presents an English chat room system in which students discuss course contents and ask questions to and receive from teachers and other students. An novel mechanism is also proposed that does not require that supervisors constantly remain online to handle queries. The mechanism contains an agent that detects syntax errors in sentences written by the online the user and also checks the semantics of a sentence. For instance, learners making a semantic level mistake imply that they do not understanding the course topic or particular issue. The agent can thus offer recommendations to the user and, then, analyze the data of the learner corpus. When users query the system or others, this system will attempt to find the answers from the knowledge ontology or learner corpus that is stored in the records of previous user comments. If a sufficient number of QA pairs can be obtained, the FAQ can be provided for the learners. With the availability of automatic supervisors, messages can be monitored and syntax or semantic mistakes can be corrected to resolve learner-related problems.

This article has two main goals about verifying the ideas of the Dual Autonomy Model (Yeh & Yang, 2006; Yeh, Bedford, & Yang, 2007; Yeh, Liu, Huang, & Yang, 2007). The first is testing the collective effect of dual autonomy and situational operation on message discernment to support the processing mechanism of the domain superiority hypothesis. The second is using the message discernments as performance criteria variable to prevent the common method variance bias and replicate the each hypotheses of dual autonomy. In study 1, 811 senior high school students from north and south of Taiwan as participants were asked to complete a group-survey in their classrooms. A medium correlation between individuating autonomy (IA) and relating autonomy (RA) replicates the coexistence hypothesis. It was also found a distinguishable criterion-validity confirms the domain superiority hypothesis that IA was greater associated with personal domain message discernment but RA was greater associated with interpersonal domain message discernment. This effect of domain superiority was enhanced only under the congruous situational operation condition, shows the collective effect of situation and autonomy capacity that verifies the processing mechanism of domain superiority. For strengthening the result of study 1, study 2 improves the situational operation materials and the message discernment tasks. 61 college students whose dual autonomy both are higher and 63 college students whose dual autonomy both are lower were recruited as participants for study 2 from school in north of Taiwan. They were invited to a small room separately and asked to complete all of the materials and tasks that were presented on computer. The participants with higher dual autonomy have better message discernments of both domains than the participants with lower dual autonomy, replicates the effect of dual autonomy on message discernments. The congruous situational operation produced greater message discriminations than incongruous or none situational operation. This situational effect was only significant on the participants with higher dual autonomy, shows the collective effect of situation and autonomy capacity, confirms the coexist of dual autonomy, and also verifies the processing mechanism of domain superiority. These results and limitations of these two studies, comparison with the past findings, and considerations for future research are discussed.

With the popularization of instant messaging software, the number of users has become larger and larger, and various types of communication software have also been launched one after another. The nature of such instant messenger software is similar to that of mobile phone telecommunications services. Instant messaging between users can be performed under the same specifications, and multimedia messages such as pictures and videos can be provided in addition to voice and text messages. There is a lack of intermediate bridges between instant messaging software, which allows users to be separated into different groups, creating barriers for users of different instant messaging software. It is very inconvenient in terms of user experience and lacks a platform between messaging software. This study will use Line and messenger instant messenger software as an example to implement cross-domain messaging paradigms through APIs provided by both of them to provide new instant messaging methods for two software users. At the same time, it will use software engineering to modularize the message receiving and sending functions so that new communication software can quickly access the system, enabling the system to rapidly expand the service audience and applying the GCP (Google Cloud Platform) cloud service. The system is built, and the GCP cloud services automatic expansion and load balancing functions enable the information transfer between the two to rely on the powerful platform resources provided by cloud services, maintain high response efficiency, and achieve the demand for cross-domain instant messaging.

Full textTransport and local translation of RNA are found in several organisms and are required for multiple phenomena such as memory, asymmetric cell division and establishment of the axis during development. Staufen, a double-stranded RNA binding protein, was first identified in Drosophila melanogaster. In the fruitfly, it was shown that Staufen is required for the proper localization of the bicoid and oskar transcripts to the anterior and posterior ends of the oocyte, respectively. It was also found that Staufen is important for the translational derepression of oskar once it is adequately localized. In mammals, Stau1 is a ubiquitous protein found in granules in the dendrites of neurons. Also, Stau1 can bind the ribosome in a RNA-independent manner and cofractionates with both ribosomal subunits in a sucrose gradient. The implication of Stau1 in a mechanism allowing translational derepression of certain RNAs in mammals was therefore an interesting path to explore. Accordingly, we decided to verify if mammalian Stau1 had the capacity to stimulate the translation of cellular RNAs through a regulated mechanism. When this thesis was initiated, no cellular RNA target of Stau1 had been identified in mammals. Therefore, double-stranded RNA structures were used to repress the translation of a reporter mRNA. With this model, we showed that Stau1 can stimulate the translation of a transcript when it is bound to its 5’ UTR. With the use of DNA microarrays, we identified cellular mRNAs which distribution in heavy polysomes was altered by Stau1. When Stau1 is overexpressed, this group of mRNAs is enriched heavy polysomes, suggesting a translational stimulation of this population by Stau1. To identify a regulatory mechanism that could influence Stau1’s translational activity, we studied the self-association capacity of this protein. We showed that Stau1, like several double-stranded RNA binding proteins, can self-associate in a RNA-independent manner. We have identified the determinants required for this interaction that as the potential to be important for the regulation of the cellular activities of Stau1. The results presented in this thesis suggest that Stau1 can stimulate the translation of a specific subset of mRNAs in the cell, letting us look at Stau1’s implication in different processes from a new point of view.
