Abstract:
Abstract Motivation Nucleotide modification status can be decoded from the Oxford Nanopore Technologies nanopore-sequencing ionic current signals. Although various algorithms have been developed for nanopore-sequencing-based modification analysis, more detailed characterizations, such as modification numbers, corresponding signal levels and proportions are still lacking. Results We present a framework for the unsupervised determination of the number of nucleotide modifications from nanopore-sequencing readouts. We demonstrate the approach can effectively recapitulate the number of modifications, the corresponding ionic current signal levels, as well as mixing proportions under both DNA and RNA contexts. We further show, by integrating information from multiple detected modification regions, that the modification status of DNA and RNA molecules can be inferred. This method forms a key step of de novo characterization of nucleotide modifications, shedding light on the interpretation of various biological questions.

Abstract:
Reactive oxygen species (ROS) are not only harmful to cell survival but also essential to cell signaling through cysteine-based redox switches. In fact, ROS triggers the potential activation of mitogen-activated protein kinases (MAPKs). The 90 kDa ribosomal S6 kinase 1 (RSK1), one of the downstream mediators of the MAPK pathway, is implicated in various cellular processes through phosphorylating different substrates. As such, RSK1 associates with and phosphorylates neuronal nitric oxide (NO) synthase (nNOS) at Ser847, leading to a decrease in NO generation. In addition, the RSK1 activity is sensitive to inhibition by reversible cysteine-based redox modification of its Cys223 during oxidative stress. Aside from oxidative stress, nitrosative stress also contributes to cysteine-based redox modification. Thus, the protein kinases such as Ca2+/calmodulin (CaM)-dependent protein kinase I (CaMKI) and II (CaMKII) that phosphorylate nNOS could be potentially regulated by cysteine-based redox modification. In this review, we focus on the role of post-translational modifications in regulating nNOS and nNOS-phosphorylating protein kinases and communication among themselves.

Abstract:
Compared with the effects of a 6% protein diet, feeding rats a 40% protein diet for 10 days increases glomerular filtration rate and decreases the activity of the tubuloglomerular (TG) feedback control system. The decrease in TG feedback activity results from an increase in the threshold at which the loop of Henle flow rate initiates feedback responses. To determine whether this protein-dependent shift in the TG feedback response curve is caused by changes in either the signal or the sensing mechanism in the feedback pathway, we used micropuncture and microperfusion techniques to study the TG feedback system of rats fed high- or low-protein (40 or 6% casein) diets for approximately 7-10 days. Compared with the rats fed the low-protein diet, in the high-protein group distally measured single nephron glomerular filtration rate was 17% higher, and Na and Cl concentrations in early distal tubule fluid were 30-50% lower. Early distal osmolality was not different in the two groups. TG feedback responses assessed by changes in stop-flow pressure during perfusion of the distal nephron with NaCl solutions did not differ between diet groups. We conclude that the sensing mechanism in the TG feedback system is not altered by this manipulation of dietary protein, whereas the signal eliciting the TG feedback response is affected. Because rats fed a high-protein diet have higher rates of Na and Cl absorption between the late proximal and early distal tubules than do rats fed a low-protein diet, early distal Na and Cl concentrations are reduced, and the signal for TG feedback is diminished in rats fed the high-protein diet.

Abstract:
This paper presents signal structure and power efficiency performance for simultaneous transmission of Global Navigation Satellite System (GNSS) service signals based on Tiered Polyphase Code (TPC). For the simultaneous transmission of three or more service signals, the intermodulation terms addition and modification of the power allocations for the signal multiplexing are applied first to the spreading signal with the binary pseudorandom noise (PRN) code and a constant envelope signal is generated. Then, Zadoff-Chu sequence is applied as a secondary code to generate a multiplexed satellite navigation signal having a constant envelope characteristic. Simulation results show that power efficiency performance of more than 80% can be achieved in three service signal multiplexing.

Abstract:
Although historically viewed as purely harmful, recent evidence suggests that reactive oxygen species (ROS) function as important physiological regulators of intracellular signaling pathways. The specific effects of ROS are modulated in large part through the covalent modification of specific cysteine residues found within redox-sensitive target proteins. Oxidation of these specific and reactive cysteine residues in turn can lead to the reversible modification of enzymatic activity. Emerging evidence suggests that ROS regulate diverse physiological parameters ranging from the response to growth factor stimulation to the generation of the inflammatory response, and that dysregulated ROS signaling may contribute to a host of human diseases.

Abstract:
Initial investigations of the Outlier Processing Method (OPM), first introduced by Birch [1][2][3] in 1988, have demonstrated a promising ability to extract a special class of signals, called highly variable events (HVEs), from coloured noise processes. The term HVE is introduced in this thesis to identify a finite-duration signal whose shape and latency vary dramatically from trial to trial and typically has a very low signal-to-noise ratio (SNR). This thesis presents a modified version of the original OPM algorithm, which can generate an estimate of the HVE with significantly less estimation noise than the original OPM algorithm. Simulation experiments are used to identify the strengths and limitations of this modified OPM algorithm for linear and stationary processes and to compare the modified algorithm's performance to the performance of the original algorithm and to the performance of a minimum mean-square-error (MMSE) filter. The results of these experiments verify that the modified algorithm can extract an HVE with less estimation noise than the original algorithm. The results also show, that the MMSE filter is unsuitable for extracting HVEs and that its performance is generally inferior to the modified algorithm's performance. The experiments indicate that the modified algorithm can extract HVEs from a linear and stationary process for SNR levels above -2.5dB and can work effectively above -7.5dB for HVEs with certain characteristics.

Abstract:
Le domaine de recherche de la modification de durée d'un signal audio est actif depuis plus d'une quarantaine d'années. Aujourd'hui, plusieurs applications en font usage: livres audio, synthèse par échantillonnage, voix sur IP, postsynchronisation audio-vidéo, etc. Dans la plupart des cas, l'objectif des techniques de modification de durée est de modifier le débit du signal tout en y affectant le moins possible ses caractéristiques perceptuelles (tel que la tonalité). Plusieurs algorithmes de modification de durée ont été proposés pour tenter d'atteindre ce but. Ceux-ci sont caractérisés par des forces et faiblesses selon le type de signal traité. Dans le cas où l'on tente de traiter un signal de type variable, l'ensemble des techniques proposées à ce jour exhibent des artéfacts audibles qui affectent l'ensemble de la qualité subjective du signal d'origine. Une étude approfondie de l'état de l'art permet de constater que les algorithmes de modification de durée peuvent être classés sous deux familles, soit les techniques appliquées dans le domaine temporel et les techniques appliquées dans le domaine fréquentiel. Selon le domaine de traitement choisi (temporel ou fréquentiel), la qualité subjective obtenue prime sur un type de signal particulier. Par exemple, les techniques appliquées dans le domaine temporel ont la caractéristique d'être efficaces sur des signaux monophoniques, tandis que les techniques appliquées dans le domaine fréquentiel sont plus performantes sur des signaux polyphoniques ou bruités. Ce constat permet d'établir qu'il existe une complémentarité entre les techniques appliquées dans le domaine temporel et le domaine fréquentiel. Ceci motive la création d'un algorithme de modification de durée qui en tire avantage, de façon à résoudre le problème du traitement de signaux composés de plusieurs types. Cet ouvrage présente une méthode novatrice qui vise à exploiter la complémentarité observée entre les techniques appliquées dans le domaine temporel et le domaine fréquentiel. Cette méthode introduit les contributions suivantes: (1) Le choix de deux techniques de modification de durée, basé sur une étude de la qualité du signal obtenu selon le type de signal traité. (2) Une étape de classification du signal, appliquée trame par trame, permettant de choisir la technique appropriée. (3) L'introduction de dispositions permettant la transition transparente entre les techniques choisies. (4) La définition d'un ensemble de paramètres régissant l'occurrence et la fréquence des transitions entre les techniques. (5) L'adaptation du codeur de phase amélioré, permettant d'obtenir un signal de synthèse de longueur fixe. La méthode de modification de durée obtenue est caractérisée par une haute qualité subjective sur une large gamme de signaux.

Abstract:
L'objectif de cette recherche est l'elaboration d'une methode de modification du signal sonore utilisant des modeles de representation du signal adaptes a ses caracteristiques locales. A cet effet, deux modeles de representation sont etudies, correspondant chacun a une interpretation differente d'un signal sonore : la decomposition temporelle d'un signal en formes d'onde elementaires et la representation d'un signal par une somme de sinusoides variables au cours du temps. L'originalite de notre methode consiste a tirer parti des avantages de chacun des deux modeles pour la classe de signaux pour laquelle il est le mieux adapte. Cette methode hybride necessite l'estimation des parametres de chacun des deux modeles (localisation des formes d'ondes, frequence fondamentale, frequence, amplitude et phase des composantes frequentielles) ainsi que d'un ensemble de caracteristiques permettant le choix du modele le mieux adapte a la representation d'une region du plan temps/frequence donnee (singularite des formes d'onde, erreur de modelisation, erreur de specification, voisement, harmonicite). De nouveaux estimateurs sont proposes et nous montrons la pertinence de l'information de phase pour l'estimation. Dans chaque cas, les estimateurs proposes sont compares aux estimateurs communement utilises. Les methodes de modification du signal associees a ces deux modeles sont la methode psola (pitch synchronous overlap-add) et la synthese par addition de sinusoides. Les possibilites de modification du signal de ces deux methodes sont etudiees et des ameliorations sont proposees, en particulier en ce qui concerne la prise en compte des relations de phase lors de modifications d'un signal. Les deux modeles sont ensuite utilises dans une nouvelle methode hybride de modification du signal (sinola), assignant a chaque region du plan temps/frequence celui des deux modeles le plus adapte a sa representation et a sa modification.

Abstract:
As a result of high crash frequencies on roadways, transportation safety has become a high priority for the United States Department of Transportation and the Utah Department of Transportation. A large percentage of fatal and injury crashes on roadways occur at intersections and traffic signals have been implemented to reduce these severe crashes. There is a need to evaluate the effectiveness of the traffic signal improvements through the development of Crash Modification Factors (CMFs). Recent research has shown that traditional safety evaluation methods have been inadequate in developing CMFs. In recent years, Bayesian statistical methods have been utilized in traffic safety studies to more accurately analyze the effectiveness of safety improvements. The hierarchical Bayesian method is an advanced statistical technique that has the capability to account for the shortcomings of traditional methods and to more fully reflect the effectiveness of safety improvements. This report uses a hierarchical Bayesian model to analyze the effectiveness of new traffic signal installations and modified traffic signals. CMFs were developed for multiple scenarios for both new and modified traffic signals. A benefit-to-cost (B/C) analysis was also performed for each improvement to determine how long it would take to recover the cost of installation. The results showed that there was an increase in overall crashes for both new signal installations and modifications to existing signals. The severe crash analysis revealed that there was an increase in non-severe crashes and a reduction in severe crashes; the improvements are effectively reducing severe crashes and improving safety at intersections. The B/C analyses indicate that there is a safety benefit to both improvements and that new signal installation costs can be recovered in approximately 5 years while the installation of a left-turn signal modification can be recovered in approximately 9 weeks.

Abstract:
C/EBPα und C/EBPβ sind Transkriptionsfaktoren, die die Zellproliferation und Zelldifferenzierung in vielen Geweben regulieren. C/EBPα und C/EBPβ spielen auch eine onkogene Rolle in akuter myeloischer Leukämie und anaplastisch-großzelligen Lymphomen (ALCL). In dieser Studie wird C/EBPα auf neue posttranslationale Modifikationen, wie z. B. Arginin-Methylierungen und Citrullinierungen, sowie Lysin-Methylierungen und Acetylierungen, mit massenspektrometrischen Mitteln untersucht. Es werden eine modifizierbare C/EBPα-Arginin-Citrullinierungsposition und die C/EBPα-Lysinsumoylierung eingehend auf ihren Einfluss auf C/EBPα-Proteininteraktionsnetzwerk überprüft. Außerdem wurde im Verlauf dieser Studie ein Hochdurchsatz-Screening-Verfahren entwickelt, das wir Protein Interaktions-Screening auf einer Peptid Matrix (PrISMa) nennen. Dieses Verfahren dient der Aufklärung des modifikationsabhängigen Proteininteraktionsnetzwerkes von C/EBPβ. PrISMa basiert auf einer Peptidmembran, auf der C/EBPβ-Peptide synthetisiert sind. Viele dieser Peptide enthalten methylierte Arginine und Lysine, acetylierte Lysine, citrullinierte Arginine und phosphorylierte Serine, Tyrosine und Threonine. Mittels PrISMa konnten Interaktionen von C/EBPβ mit Histonacetyltransferasen, dem Mediatorkomplex, Proteinen des nukleären Transports und RNA bindenden und spleißenden Proteinen verifiziert und kartiert werden. Des Weiteren konnte mit Hilfe von PrISMa eine große Anzahl von publizierten C/EBPβ Interaktionspartner spezifischen C/EBPβ-Sequenzen zugeordnet werden. C/EBPβ wird in ALCL in hohem Maße exprimiert und ist für die Zellproliferation dieser Krebsart wichtig. In dieser Studie wird das Proteininteraktionsnetzwerk C/EBPβ in einer ALCL Zelllinie aufgeklärt, um tiefere Einsichten über die Funktion von C/EBPβ als Onkogen zu erlangen.
C/EBPα and C/EBPβ regulate cell proliferation and differentiation in multiple cell types. Moreover, C/EBPα and C/EBPβ are known to play oncogenic roles in acute myeloid leukemia and anaplastic large cell lymphomas (ALCLs). In this study C/EBPα is screened for novel posttranslational modifications (PTMs), such as arginine methylation and citrullination, as well as lysine methylation and acetylation by using mass spectrometry. A in this survey identified C/EBPα site of arginine citrullination and the C/EBPα lysine sumoylation are scrutinized for their impact on C/EBPα protein interaction network. A new high-throughput method named Protein Interaction Screen on peptide Matrices (PrISMa) is introduced in this study. This method was developed to determine the C/EBPβ protein interaction network in a PTM dependent manner. The PrISMa survey is based on a peptide membrane spotted with C/EBPβ peptides. Many of these C/EBPβ peptide sequences contain amino acid sequences comprising arginine and lysine methylation, lysine acetylation, arginine citrullination and serine, tyrosine and threonine phosphorylation. By means of PrISMa the C/EBPβ interplay with histone acetyltransferases, the mediator complex, proteins of the nucleoplasmic transport and RNA processing proteins is verified and specified by mapping these interactions to C/EBPβ amino acid sequences. Furthermore, PrISMa provides a map of C/EBPβ protein interaction patterns for a great number of the up to date published C/EBPβ protein interaction partners. C/EBPβ is highly expressed in ALCL cell lines and is essential for the cell proliferation of this type of cancer. In this study the C/EBPβ protein-protein interaction pattern in an ALCL cell line is unraveled providing valuable insight into the protein interaction network of C/EBPβ as an oncogene.

Abstract:
This chapter discusses the epigenetic mechanisms involved in individual variation in and persistence of post-traumatic stress disorder (PTSD). Such mechanisms make it possible to trace vulnerability for PTSD to effects that predate development of PTSD. While some may be genetic in origin, others may involve parental stress occurring pre-conception, in utero changes in the maternal environment contributing to developmental programming, and childhood adversity, resulting in modifications of genes’ contribution to PTSD risk. The chapter discusses epigenetic alterations implicated in hypothalamic–pituitary–adrenal (HPA) function in PTSD that mark increased risk. Unlike the transient alterations in neural, endocrine, or immunological signals that follow exposure to trauma, certain epigenetic markers can be chemically stable over extended periods and can serve as a basis for understanding the persistence of PTSD symptoms. The chapter concludes with a discussion of how epigenetic modification may offer insights into future treatments for PTSD.

Abstract:
What does pain look like? Charles Darwin’s The Expression of the Emotions in Man and Animals (1872) includes a well-known list of the visible and physiological signs of pain. Published a year after The Descent of Man, it sets out to show that the human face is the product not of divine fashioning, but of descent with modification. Joy, melancholy, fear, disgust, contempt, anguish: for Darwin, the body language of human emotion – and pain – provides compelling evidence for evolution, and his account of pain appropriately begins in the animal kingdom. There are some major obstacles to the study of emotional expression, however. The facial movements involved, notes Darwin, are often ‘extremely slight, and of a fleeting nature’.

Abstract:
Electrical research in geology is used quite widely and with great efficiency. The use of ready-made signal recorders for these purposes is possible, but not effective enough, since in any case, they need to be modified to provide additional functions. Such functions include the synchronization of measurements with signals from positioning systems GPS or GLONASS. This synchronization is necessary in order for the measurement results to be linked to actual space and time coordinates as accurately as possible. The same measurements taken at different times may give different results due to changes in the orientation of the Earth relative to the Sun and Moon, as well as for other uncontrollable reasons. The need to accurately determine the coordinates of the measurement is obvious. The creative team of the commonwealth of organizations, the key of which is the Siberian Branch of the Federal State Budgetary Institution of Science of the Federal Research Center “Unified Geophysical Service of the Russian Academy of Sciences”, carried out the development and initial testing of a specialized signal recorder for electrical research. The additional modification was required to eliminate the identified deficiencies. This paper reports the main technical solutions when creating this recorder, describes the modification ,and gives an example of using this recorder for field measurements.

Abstract:
The article is devoted to the analysis of the main forms of visualization in the media related to photo. The thematic visual concepts are described in accordance with the content of electronic media, which consider the impact of modern technologies on the development of media space. The researches of the Ukrainian and foreign educational institutions concerning the main features of modern photo is classificate. Modifications and new visual forms in the media are singled out. The main objective of the article is to study the visual concepts of modern photo and identify ideological and thematic priorities in photo projects. To achieve the main objective in the article a certain methodology were used. Due to the historical-theoretical description it was possible to substantiate the study of visual concepts. The conceptual-system method was used to study the subject of media photo projects. The main results of the research are the definition of visual concepts of photo on the example of electronic media and the identification of the main thematic features in the process of visual filling of the media space. Based on the study, we can conclude that today the information field needs quality visual content. For successful creation of visual concepts it is necessary to single out thematic features of modern photo and to carry out classifications on ideological and semantic signs. Given the rapid development of digital technologies, the topic of the scientific article we offer is relevant for scientists, journalists, media researchers, visual journalism experts and photojournalists. Modern space is filled with a large number of pictorial materials, which in most cases form specific images, patterns or stereotypes in the mind of the reader (viewer). Also important is the classification of photo used in journalistic publications. That is why there is a need to explore the content and principles of distribution of ideological priorities of photo in the media. The substantiation of scientists about the important place of photography in the modern media space and the future development of visual technologies, which already use artificial intelligence, is relevant.
