PHF1 is required for chromosome alignment and asymmetric division during mouse meiotic oocyte maturation

ABSTRACT In recent years, the etiological study of oocyte maturation failure and other mechanisms of early embryonic development has gradually advanced. However, while some achievements have been made in this field, the intrinsic mechanisms underlying disordered oocyte maturation remain unclear. Polycomb group proteins (PcG) are a family of proteins that are involved in the epigenetic silencing of genes. Many members of this family are reportedly involved in mammalian oocyte maturation and early embryonic development. PHD finger protein 1 (PHF1) is a core member of the polycomblike group of proteins, although its role in oocyte maturation and early embryonic development are unknown. A previous study by our group using single cell transcriptome analysis and high-throughput technology revealed that PHF1 mRNA was elevated in the human oocyte and the early preimplantation embryo. This suggests that PHF1 may play an important role in oocyte maturation and early embryonic development. In the present study, we aimed to reveal the biological function of PHF1 in mouse oocyte maturation and illuminate its regulatory mechanisms. We report here, for the first time, that PHF1 is necessary for the accurate alignment of chromosomes and oocyte euploidy, as well for the regulation of the asymmetric division of oocytes in mouse. The results of the present study may have the potential to provide a new research direction of human oocyte maturation disorder and early embryonic development block. These results may also provide new diagnosis or treatment strategies for clinical patients.
CORPUS-BASED APPROACH TO TEACHING PHRASEOLOGICAL UNITS FOR FOREIGN LEARNERS

The study is to show how corpus-based methods map out the strategy for helping with the acquisition of idiomatic expressions and figures of speech. The aim of this approach is to provide students with scaffolds relying on which they will be able to develop their metaphoric competence and take fun out of learning at the same time. Idioms represent an essential characteristic of effective communication. Harold E. Palmer determined phraseology as the key to fluency in a foreign language. On the other hand, mastering idioms presents severe difficulties related to remembering, semantization and performance. Corpus-based approach provides a means of constructing a lexico-grammatical word profile: its general context, syntactic patterns, semantic prosody. All these aspects taken into account help learners come to grips with the grammatical company the idioms keep and their discourse. For example, to provide solid language skills and depth of cultural understanding many programs of university curricula require students to read classical books on a par with modern literature, which very often creates confusion as the students are unable to decipher which idiomatic expressions belong to the active or to the passive vocabulary of native speakers, which age groups use this or that idiom. Among Russian learners such idioms as it's raining cats and dogs, my cup of tea are very popular, though they might bring a smile or confusion to English speakers. The same story is with the French idioms un averti en vaut deux and mener quelqu'un en bateau. In this regard, it is essential for a teacher to have an array of resources to maximize the learning process and to put across the importance of verifying the figurative usage of idiomatic expressions via language corpora, thus bringing diverse, reliable and authentic data in class. The use of corpora in class is known as data-driven learning, when learners act as researchers of the language rather than imitators. As a basic premise, corpus-based approach to teaching should rest on several main principles: accessibility and clarity of tasks (guiding principle) as well as learners' motivation. Taking into account all the benefits of data-driven learning we implemented corpus-based tasks in foreign language classes to see how they can help students to enhance their knowledge of the languages they study and their culture. The benefits of such tasks is their productivity. The outcome was the increased awareness of the aspects of the usage in sentences and connotation of phraseological units. Moreover it developed students' autonomy and cognitive skills.
Does muscular activity related to vertical facial divergence influence the time needed for orthodontic extrusion of palatally impacted maxillary canines? A retrospective study

Background The aim of the present study was to evaluate if the different muscular activity correlated to different degrees of facial divergence has an effect on the time needed to extrude a palatally impacted maxillary canine. Material and Methods Twenty-six patients were retrospectively selected, all treated with a specific cantilever appliance that allows extrusion of the impacted canine applying a physiologic amount of force below 0.6 N in a predictable way. For all the patients, pre-treatment cephalometric tracings were used to evaluate facial divergence through the FMA angle, the angle between the maxillary and mandibular plane, and the angles between the occlusal plane and either the maxillary and mandibular plane. Linear bivariate regression was calculated to evaluate if facial divergence can predict the time needed for canine extrusion. Results The linear regression model was not able to predict extrusion time from variables explaining the facial divergence. Conclusions Palatally impacted maxillary canines can be treated with the application of physiologic extrusion force regardless of patients’ facial divergence and muscular activity. Key words:Impacted canines, cantilever, facial divergence, muscular activity.
A PROBLEM OF THE NOISY VARIABLES IN THE AGGREGATED KNN CLASSIFIERS

własną propozycją algorytmu. czonymi Summary: Ensemble learning in discrimination and regression has gained a great apprecia tion due to the improved stability of the model, and often improved accuracy of the predic tions. Aggregating of k nearest neighbors classifiers (kNN), however, faces serious problems. The kNN method, which uses only the distances between objects, is relatively stable, so the diversity of base classifiers can only be achieved by choosing different subspaces. Here, in turn, we encounter the problem of noisy variables, those that do not affect the response var -iable, and which result in decreasing the accuracy of the kNN classifier. This article reviews the methods of the aggregated kNN classifiers, which were proposed in the literature. We also verify our own proposition of the algorithm. The real data with noisy variables added are used in the empirical study.
Causation of the ontogenetic development of stereotypic digging in gerbils

To determine the factors that cause the development of stereotypic digging, features in the captive environment of young Mongolian gerbils,Meriones unguiculatus, were varied. It was hypothesized that stereotypic digging develops because stimuli that control digging motivation are lacking. A regulatory model of motivation was used to examine whether digging motivation is decreased by the performance of the motor pattern ‘digging’ or by the consequences of digging. Young gerbils that could dig in a sand area developed stereotypic digging. In contrast, young gerbils that could not dig in sand but had access to an artifical burrow, which was presumed to be the consequence of digging, showed less non-stereotypic digging than gerbils from the sand treatment and did not develop stereotypic digging. Therefore, the mere perception of the stimulus ‘burrow’ by a retreating animal decreased digging motivation. The complexity of the artifical burrow was reduced to a few elements to analyse in detail the stimuli that control digging motivation. A dark and narrow chamber at the end of a tube connected to the cage provided the stimuli that elicited retreating and prevented the development of stereotypic digging. The tube was a necessary feature: a chamber alone did not prevent the development of stereotypic digging. Such a stimulus situation seems to match the stimuli of a natural burrow which is built to buffer climatic fluctuations and to provide shelter from predators. The results show that stereotypic digging develops when a young gerbil cannot achieve a stimulus situation that is efficient in decreasing digging motivation.
The Influence of the Presentation of Camera Surveillance on Cheating and Pro-Social Behavior

Introduction: This study is aimed at gaining more insight into the effects of camera-surveillance on behavior. It investigates the effects of three different ways of “framing” camera presence on cheating behavior and pro-social behavior. First, we explore the effect of presenting the camera as the medium through which an intimidating authority watches the participant. Second, we test the effect of presenting the camera as being a neutral, non-intimidating viewer. Third, we investigate the effect of watching oneself via a camera. In contrast to most studies on camera surveillance, we will conduct our experiments in an indoor setting. We also explore possible interaction effects of personality traits; we measured Locus of Control, Need for Approval, Self-Monitoring and Social Value Orientation. Methods: In this experiment participated 86 students, randomly distributed over four conditions: three different ways of framing the camera presence, plus a control condition. Our main dependent variables were various kinds of cheating and pro-social behavior. We established the participant's relevant personality traits using a classification tree. Results: For cheating behavior, findings showed that in the “authorative” way of framing camera presence and in the situation in which participants viewed themselves, participants cheated significantly less compared to a situation without camera-surveillance. We did not find significant effects of camera surveillance on pro-social behavior. Looking at personality traits, we found an indication that people with an internal locus of control are more inclined to cheat when there is no camera present compared to people with an external locus of control. However, the effects of our manipulations were stronger. Conclusion: Our findings support the idea that the framing of a camera's presence does indeed influence cheating behavior, adding to the preventive effects of camera-surveillance. Additionally, this study provides some valuable insights into the influence of camera presence on behavior in general.
Underwater acoustic displays and individual variation in male harbour seals, Phoca vitulina


Abstract Abstract. Vocalizing by natural-living harbour seals has been considered to be rare, limited primarily to aerial threats. A few studies on captive harbour seals, however, indicated that this species produced a wider variety of aerial vocalizations than was previously thought. The objective of this study was to determine whether adult male harbour seals in the wild vocalized under water during the breeding season and whether there was any variation in vocalizations between individuals. Underwater vocalizations of 10 males were tape-recorded at Point Lobos State Reserve, California during the spring and summer of 1991. Females did not vocalize except on land when they threatened other seals. Observational data was taken to identify the vocalizing seal and to determine whether other seals in the vicinity showed any reactions to the vocalizations. Five vocalization types were identified and analysed: grunt, groan, creak, bubbly growl and roar. There were significant differences between males with regard to the frequency measurements of the roars as well as to their entire acoustic displays but there was little intra-individual variation. It is suggested that underwater vocalizations are used in male-male competition and/or as reproductive advertisement displays to attract females.
Dilated DenseNets for Relational Reasoning

Despite their impressive performance in many tasks, deep neural networks often struggle at relational reasoning. This has recently been remedied with the introduction of a plug-in relational module that considers relations between pairs of objects. Unfortunately, this is combinatorially expensive. In this extended abstract, we show that a DenseNet incorporating dilated convolutions excels at relational reasoning on the Sort-of-CLEVR dataset, allowing us to forgo this relational module and its associated expense.
Vaizdinės grįžtamosios informacijos poveikis skirtingo amžiaus moterų pėdos lenkimo ir tiesimo judesių kaitumui ir tikslumui

Vaizdinė grįžtamoji informacija labai svarbi žmogaus judesių valdymo procese, ypač izometrinių raumens susitrauki-mų metu. Vaizdinės grįžtamosios informacijos pagrindinis uždavinys judesių valdymo procese yra kuo greičiau kore-guoti jėgos dydį ir sumažinti judesio atlikimo laiką, kaitumą. Atliekant judesį be grįžtamosios informacijos, pailgėja jo atlikimo laikas. Vyresniojo amžiaus tarpsniu tai gali sukelti eisenos sutrikimų ir padidinti griuvimo riziką. Šio tyrimo tikslas — nustatyti grįžtamosios informacijos poveikį skirtingo amžiaus moterų pėdos lenkimo ir tiesimo judesių kaitumui ir tikslumui. Buvo tiriama 30 sveikų skirtingo amžiaus moterų. 1 grupė — amžiaus vidurkis 70 ± 5 m. (n = 15), 2 grupė — amžiaus vidurkis 25 ± 5 m. (n = 15). Tiriamosios buvo testuojamos žmogaus kaulų ir raumenų testavimo bei reabilitacijos aparatūra „Biodex Medical System 3“. Jos atliko dešinės pėdos izometrinį lenkimo ir tiesimo judesį suteikiant grįž-tamąją informaciją ir be jos. Judesio tikslumas ir kaitumas buvo skaičiuojamas pagal R. A. Shmidt, T. D. Lee (1999) ir R. A. Magill (2007) pasiūlytą metodiką. Rezultatai parodė, kad visų tiriamųjų maksimaliosios valingos jėgos momentas lenkiant pėdą yra statistiškai reikš-mingai (p < 0,001) didesnis nei ją tiesiant. Jaunesniojo amžiaus tiriamųjų maksimaliosios valingos jėgos momentas lenkiant pėdą yra statistiškai reikšmingai (p < 0,05) didesnis nei vyresniojo amžiaus tiriamųjų. Atliekant pėdos lenkimo ir tiesimo judesius be grįžtamosios informacijos, visų tiriamųjų judesių tikslumas sumažėjo statistiškai reikšmingai (p < 0,05). Vyresniojo amžiaus tiriamųjų pėdos lenkimo ir tiesimo judesių tikslumas statistiškai reikšmingai (p < 0,05) mažesnis nei jaunesniojo amžiaus tiriamųjų. Visų tiriamųjų pėdos lenkimo judesių kaitumui grįžtamoji informacija statistiškai reikšmingo poveikio neturėjo. Atliekant pėdos tiesimo judesius be grįžtamosios informacijos, visų tiriamųjų judesių kaitumas statistiškai patikimai (p < 0,05) padidėjo. Lenkiant ir tiesiant pėdą jaunesnės tiriamosios statistiškai reikšmingai (p < 0,05) tikslesnės nei vyresniojo amžiaus. Raktažodžiai: senėjimas, judesių valdymas, tikslumas, kaitumas.
Geschlecht und Differenz in Organisationen: Von Gleichstellungspolitik und erfolgreichem Organisationslernen

In die Geschlechterfrage ist Bewegung gekommen: Inzwischen werden geschlechtsspezifische Benachteiligungen auf dem Arbeitsmarkt, in Politik, Medien und Unternehmen eingestanden und der Handlungsbedarf wird anerkannt. Dies gilt zumindest für Forderungen wie die nach mehr Krippenplätzen, gleicher Bezahlung oder danach, Maßnahmen gegen die Unterrepräsentanz von weiblichen Führungskräften zu ergreifen. Diese Themen finden sich in Programmen von Parteien und Gewerkschaften und werden in der politischen Sphäre verhandelt. Weniger akzeptiert und heftiger umstritten sind dagegen Themen wie die missliche Situationen von Migrantinnen auf dem Arbeitsmarkt, von Hartz IV-Empfängerinnen oder von weiblichen Beschäftigten auf schlecht bezahlten Erwerbsarbeitsplätzen am unteren Ende der betrieblichen Hierarchien. Innerhalb der Berufswelt sind die Optionen für Frauen mittlerweile vielfältiger geworden, allerdings lässt sich auch hier kein einheitliches Bild zeichnen. Gegenläufige und ambivalente Entwicklungen zwischen Wandel und Veränderungsresistenzen stehen nebeneinander. Auf der einen Seite gibt es Anzeichen dafür, dass es nicht mehr selbstverständlich und unhinterfragt hingenommen wird, hoch qualifizierte Beschäftigtengruppen aufgrund des Geschlechts aus betrieblichen Führungspositionen auszuschließen. Auf der anderen Seite zeigt ein Blick in die Arbeitsmarkt„Schaltstellen“ bei der Herstellung oder Relativierung von Geschlechterasymmetrien. Dass Geschlechtertrennungen in Organisationen deutlicher ausgeprägt sein können als auf dem Arbeitsmarkt insgesamt, belegen mittlerweile zahlreiche Studien (z.B. Acker 2006; Müller 2005; Wilz 2002; Allmendinger/Podsialkowski 2001). Beschäftigte bzw.Arbeitsuchende werden von Personalverantwortlichen für Arbeitsplätze ausgewählt und eingestellt, ihnen werden Weiterbildungsmaßnahmen angeboten, sie werden motiviert, befördert, versetzt oder demotiviert und entlassen. Annahmen über männliche und weibliche Lebensbereiche, über Kompetenzen, Eigenschaften und Verfügbarkeiten von Männern und Frauen fließen in die Praktiken, Routinen und Strukturen von Organisationen ein. Das aber bedeutet: Um grundlegende Wandlungsprozesse in Organisationen herbeizuführen, müssen genau diese Praktiken, Routinen und Strukturen auch grundlegend hinterfragt und verändert werden. Dabei gibt es große Unterschiede zwischen Organisationen – abhängig von der jeweiligen Organisationsstruktur und -kultur Geschlecht und Differenz in Organisationen: Von Gleichstellungspolitik und erfolgreichem Organisationslernen Birgit Riegraf

Detection and location of moving and unmoving people behind obstacles

This paper features the technology for identifying the location of real people behind the barriers in real time using the UWB sensing. The opportunity to obtain the radar images of moving and not moving people was presented in this paper. The oscillation rate of a human chest can be defined by the continuous recording the not moving person. The point of this technique is in calculation of the differential signal in successive periods of time. The range of application to be extended considering the particular conditions. The research results can be used in intelligence service as well as for searching people trapped under the rubble.
Nonlinear Robust Adaptive Multi-Modal Vibration Control of Bi-Electrode Micro-Switch with Constraints on the Input

Micro functionally graded material (FGM) structures are able to have proper functions in vast environments. In this paper, nonlinear governing equations of the size-dependent micro-switch are derived using modified couple stress theory. Effective external forces including fringing field of electrostatic force and Casimir force are considered. Two electrodes cooperate to track the in-plane motions of the micro continuous system by tuning the supply voltages of the electrostatic force. An adaptive projection law is proposed to compensate for the effect of error in the initial estimates of system parameters. To achieve more reliability, a robust active vibration strategy is presented to withstand external disturbances. At any time, just one electrode is operational, and optimization is performed to decrease the controller gains. The highly nonlinear inputs have a singularity in the dynamics of the system, which are known as pull-in instability, so for safety, the controller gains are chosen such that the pull-in voltage is avoided. The dynamic response of the system is simulated using a single mode or multiple modes to validate the effectiveness of the presented vibration control approaches. The effects of error of the initial estimate of system parameters, the effect of impulse and the influences of various volume fractions are studied.
Top-N Recommendation Model Based on SDAE

Collaborative filtering is the mainstream approach to personalized recommendation. For the cold start problem faced in collaborative filtering, it is a hot research topic to introduce the user’s side information into the recommendation model. Different from the matrix decomposition idea adopted in the existing methods, we propose a Top-N recommendation model using the side information of the user based on the reconstruction function of the stacked denoising auto-encoder. Experimental results show that the model outperforms the existing method in Recall. In addition, we explore the influence of missing ratings and user side information vector into the loss computation. The experimental results show that ignoring the missing ratings in the loss function is beneficial to improve the performance of the model.
Scrounging facilitates social learning in common marmosets, Callithrix jacchus


We investigated the effect of close social interaction on the ability to learn a new behaviour via observation. The task chosen involved sliding a small door horizontally to gain access to a food reward. We divided 59 common marmosets into five groups that received different pretest experience: observation of a trained demonstrator through wire mesh (O); joint interaction with a trained demonstrator allowing the possibility of scrounging (S); individual interaction with the apparatus (I); joint interaction with another naive individual (J); and no prior experience (control, C). Significantly more individuals from the scrounging group learned the new behaviour, compared with the group (O) that had purely observational experience. When animals from group O were later allowed to interact jointly with a trained demonstrator, the success rate of this group significantly increased. Social interaction with the demonstrator may have facilitated learning because it allowed subjects to understand the relation between the apparatus and the food or because social support facilitated interaction with the apparatus. However, results from the other conditions suggest that these factors alone do not account for the size of the effect. Thus, contrary to previous investigations of this phenomenon, scrounging facilitated social learning. This result probably depended on a complex interaction of a number of factors, including individual learning opportunities, social support and closer attention to the demonstrator.

Dirichlet Variational Autoencoder for Text Modeling

We introduce an improved variational autoencoder (VAE) for text modeling with topic information explicitly modeled as a Dirichlet latent variable. By providing the proposed model topic awareness, it is more superior at reconstructing input texts. Furthermore, due to the inherent interactions between the newly introduced Dirichlet variable and the conventional multivariate Gaussian variable, the model is less prone to KL divergence vanishing. We derive the variational lower bound for the new model and conduct experiments on four different data sets. The results show that the proposed model is superior at text reconstruction across the latent space and classifications on learned representations have higher test accuracies.
