Nonlinear all-optical technology is an ultimate route for the next-generation ultrafast signal processing of optical communication systems. New nonlinear functionalities need to be implemented in photonics, and complex oxides are considered as promising candidates due to their wide panel of attributes. In this context, yttria-stabilized zirconia (YSZ) stands out, thanks to its ability to be epitaxially grown on silicon, adapting the lattice for the crystalline oxide family of materials. We report, for the first time to the best of our knowledge, a detailed theoretical and experimental study about the third-order nonlinear susceptibility in crystalline YSZ. Via self-phase modulation-induced broadening and considering the in-plane orientation of YSZ, we experimentally obtained an effective Kerr coefficient of

IV AENC e integración laboral de las personas con discapacidad: ¿nuevo impulso para la negociación colectiva?
Authors: Barbancho Tovillas Fernando , Romeo Marina , Yepes-Baldó Montserrat 
Published: January 2020

El presente artículo analiza el contenido del IV Acuerdo para el empleo y la negociación colectiva para los años 2018-2020, y hace una valoración crítica de este, analizando, por un lado, si contiene concreciones y regulación específica o supone una mera declaración de intenciones, y por otro, el grado de novedad de sus formulaciones. Cabe concluir que el AENC supone una mera declaración de intenciones y, sobre todo, reiteraciones de aspectos y cuestiones previstos en la normativa que afectan e inciden en el empleo ordinario de las personas con discapacidad, más que plantear líneas de actuación futura o novedades. En el futuro habrá que constatar si los convenios colectivos recogen estas orientaciones y objetivos generales en acciones concretas que obliguen al empresariado a hacer algo real y efectivo para la integración laboral, más allá de las buenas intenciones y de reiterar lo establecido en la normativa vigente con carácter general.
Определение географических координат археологических объектов с помощью старых карт

Published: January 2020

Задача точного определения координат археологических объектов возникает в процессе анализа освоения территорий населением в разные исторические периоды. Наиболее близкие к действительности карты позволят получить более точные результаты. В настоящее время эта задача ставится в общем виде при построении геоинформационных систем (ГИС) отдельных памятников, комплексов памятников или обширных территорий. До этого перед археологами в принципе не стояла задача составления ГИС и высокоточного определения координат исследуемых объектов. При решении данной задачи основной проблемой является отсутствие информации по географическим координатам объектов, что критично в том случае, если самого объекта уже не существует. В качестве примера можно привести территорию исторического Хорезма, многие памятники которого были потеряны в результате сельскохозяйственного освоения земель.
Чтобы получить координаты не существующих в настоящее время памятников, можно воспользоваться спутниковыми снимками конца 1960-х — 1970-х гг., однако исследуемый объект должен быть хорошо заметен из космоса. При плохой сохранности памятника единственной возможностью для определения его географических координат является использование археологических карт, например, составленных Хорезмской экспедицией.
Основная идея состоит в том, что если определить локальные координаты не существующих в наше время памятников относительно сохранившихся до нашего времени памятников (назовем их опорными объектами), то, зная современные географические координаты опорных объектов, можно найти координаты несуществующих объектов. Точность нахождения координат определяется точностью, с которой составлены археологические карты. Поэтому возникает задача определения географических координат памятников с максимально возможной точностью с помощью археологической карты.

OBJECTIVES:
Conventional colonoscopy with white light illumination detects colonic adenomas based on structural changes alone and is limited by a high miss rate. We aim to demonstrate an integrated imaging strategy that combines wide-field endoscopy and confocal endomicroscopy in real time to visualize molecular expression patterns in vivo to detect premalignant colonic mucosa.

METHODS:
A peptide specific for claudin-1 is labeled with Cy5.5 and administrated intravenously in genetically engineered mice that develop adenomas spontaneously in the distal colon. Wide-field endoscopy is used to identify the presence of nonpolypoid and polypoid adenomas. Anatomic landmarks are used to guide placement of a confocal endomicroscope with side-view optics to visualize claudin-1 expression patterns with subcellular resolution.

RESULTS:
Wide-field fluorescence images show peak uptake in colon adenoma at ∼1 hour after systemic peptide administration, and lesion margins are clearly defined. Further examination of the lesion using a confocal endomicroscope shows dysplastic crypts with large size, elongated shape, distorted architecture, and variable dimension compared with normal. The mean fluorescence intensity is significantly higher for dysplasia than normal. Increased claudin-1 expression in dysplasia vs normal is confirmed ex vivo, and the binding pattern is consistent with the in vivo imaging results.

DISCUSSION:
Wide-field endoscopy can visualize molecular expression of claudin-1 in vivo to localize premalignant colonic mucosa, and confocal endomicroscopy can identify subcellular feature to distinguish dysplasia from normal.
A study of pine resin in softwood by 1D and 2D time-domain NMR
Authors: Xin Gao , Fan Zhou , Zongying Fu , Yongdong Zhou 
Published: January 2020

Abstract
Time-domain nuclear magnetic resonance (TD-NMR) is widely used in the investigation of wood-water relationship. However, some ambiguities between the NMR signals and the components in wood remain unresolved, particularly the effect of pine resin on NMR signals. To clarify these ambiguities and increase the use of TD-NMR in wood research, different sample treatment methods were studied, including air-drying, low-temperature vacuum-drying, diethyl ether extraction and moisture isothermal adsorption. The corresponding one-dimensional (1D) T1, T2 and two-dimensional (2D) T1-T2 correlation relaxation time distributions of radiata pine and Douglas fir samples were investigated. The NMR signals accounted for “longer relaxation-time components” below the fiber saturation point (FSP), but overlaped in parts of the 1D relaxation time distributions making it difficult to distinguish between pine resin and moisture. The 2D T1-T2 correlation relaxation time distributions produced a better distinction between pine resin and bound water. This distinction established a quantitative relationship between pine resin, moisture and 2D NMR signal amplitudes.
Queering kinship, overcoming heteronorms
Authors: Lasio Diego , Oliveira João Manuel De , Serri Francesco 
Published: January 2020

Abstract
Although same-sex couples and their offspring have been legitimised in many European countries, heteronormativity is still embedded in institutions and practices, thereby continuing to affect the daily lives of LGBT individuals. Italy represents a clear example of the hegemonic power of heteronormativity because of the fierce opposition to recognising lesbian and gay parenthood among many parts of society. This paper focuses on the peculiarities of the Italian scenario with the aim of highlighting how heteronormativity works in contemporary neoliberal contexts. By drawing on queer and feminist perspectives, the article also analyses how LGBT equal rights demands can contribute, to some extent, to reinforcing heteronormativity. Implications concerning strategies for challenging the regime of normality and queering kinship are discussed.
On the political aspects of Agnes Heller’s ethical thinking
Authors: Hála Vlastimil 
Published: January 2020

Abstract
The author describes Heller’s concept of ethics as a “quasi-sphere” intersecting with various fields relating to human relationships. Special attention is paid to the axiological aspects of her concept of ethics and the relationship between virtues and responsibility. The author also seeks to show how Heller integrated a traditional philosophical question—the relationship between “is” and “ought to be”—into her concept of “radical philosophy” at an earlier stage in the development of her philosophy. She initially considered the relationship between “is” and “ought to be” to be contrasting. Later, when she had come to accept the political model of liberal capitalist society, the ideal of all-compassing equality became the ideal of “equality of opportunities”. The author interprets this shift as one in which the relationship becomes continual. He is also critical of Heller’s underestimation of the effect the “social a priori” has on the possibilities of human life.
Optimized Dynamic Bandwidth Allocation Algorithm for Optical Access Networks
Authors: Singhal Ankur , Gupta Amit , Bakshi Surbhi 
Published: January 2020

Abstract
Bandwidth assignment is a key issue in optical access networks, so an efficient mechanism is required for dynamic distribution of limited resources in the uplink channel among competing subscriber optical network units (ONUs). This paper presents a novel optimized dynamic bandwidth allocation (ODBA) algorithm for hybrid WDM/TDM passive optical networks. ODBA algorithm operates using information frame length of the subscriber’s ONUs and their information arrival rate; both of these factors finalize the assigned transmission capacity to the users. The system performance under differing offered traffic loads is evaluated in terms of network throughput, average delay and channel utilization. Further, the proposed ODBA scheme is validated by performing a comparative analysis with well-known algorithms.

Published: January 2020

AbstractBackgroundPuberty is the period of human growth and development. To determine the onset of puberty with regards to the effect of higher adiposity, together with growth parameters of the participants at various stages of sexual maturity for both sexes.MethodsThe study was conducted on 1944 children (8–16) years; 1022 girls (52.6%) and 922 boys (47.4%) were taken at random. Pubertal assessment was done using Tanner staging that assigned breast development in females and pubic and axillary hair in males and females. Testicular volume was recorded using a Prader orchidometer. Height, weight, body mass index (BMI), body mass (BM) fat, body fat percentage, through applying a body impedance analyzer, and others were recorded.ResultsThe mean ages at the onset of puberty for females and males in our study were 10.29 ± 1.1 and 11.34 ± 1.02 years, respectively. Pubic hair (stage PH2) was attained at mean age of 10.72 ± 0.84 and 11.98 ± 1.03 years for females and males, respectively. For axillary hair (stage AH2), the mean age was 12.47 ± 0.68 years for females and 13.8 ± 0.58 years for males. The mean age at menarche was 12.41 ± 0.65 years. In concordance to BM fat and percentage, all pubertal stages started earlier in females with BMI ≥85th percentile comparable to females within average BMI. As for males, no significant relation was noted between mean pubertal ages and BMI values.ConclusionsA significant association of mean ages of Tanner stages to excess weight especially in females warranted the increasing awareness about health care, nutritional aspects, and living circumstances.
Sincere or heart-felt?: Sincerity, convention, and bilingualism in French and Spanish letters
Authors: Thomas Jenelle 
Published: January 2020

Abstract
The concept of sincerity has links to honesty, openness, and authenticity, including of feelings. As expressions of sincerity become formalized in epistolary practice, however, a tension arises between sincerity and the articulation of it. An examination of a corpus of private family letters in French and Spanish from the eighteenth and nineteenth centuries shows that use of the word ‘sincerity’ is much more common as an epistolary formula in French, where it had a broader semantic range, while authors writing in Spanish use other methods to index truth and emotional openness. The most frequent users of this formula are shown to be less skilled writers and bilinguals writing in their second language, suggesting a greater reliance on preconstructed formulae, especially in situations of increased linguistic and social distance. Finally, some bilingual authors transfer the pattern into Spanish, indicating that fixed phrases and formulae are available in a bilingual’s linguistic repertoire for pragmatic redeployment.
Stress Characteristics and Overload Failure Analysis of Cemented Sand and Gravel Dam in Naheng Reservoir
Authors: Wang Zhaoqiang , Chen Xin 
Published: January 2020

Abstract
On the basis of the Naheng Reservoir Project, the stress, strain, and deformation of Naheng Reservoir cemented sand and gravel dam are simulated numerical simulation and structural model test. The stress and deformation laws of the dam under the combined load of dead weight and normal water level are analyzed using the structural model test method. Compared with the finite element numerical simulation, the results reflect the stress and deformation distribution law of the dam. Then, the failure mode of the cemented sand and gravel dam can be visualized by using the water load overload method to conduct the structural model failure test, and the failure mode and failure mechanism of the cemented sand and gravel dam can be discussed. The research results lay a foundation for further determining the safety degree analysis of cemented sand and gravel dam.

). Hierdurch sind mechanische und thermische Energie direkt miteinander verknüpft, was physikalisch einen prinzipiellen Fortschritt darstellt. Die neue Definition ist allerdings sehr abstrakt, denn es gibt keinen Bezug zu Vorschriften für die Darstellung der Einheit. Praktische Anleitungen („Mise en Pratique“) wurden deshalb von internationalen Gremien ausgearbeitet. Eine zentrale Rolle spielt hierbei die Primärthermometrie, die direkt auf den Gesetzen der Thermodynamik basiert. Die Neudefinition tangiert aber nicht die Rolle der Internationalen Temperaturskalen, so dass sich am bewährten gestaffelten System rückgeführter Temperaturmessungen nichts ändert.
The Effects of a TMS Double Perturbation to a Cortical Network
Authors: Cameron Ian G. M. , Cretu Andreea L. , Struik Femke , Toni Ivan 
Published: January 2020

AbstractTranscranial magnetic stimulation (TMS) is often used to understand the function of individual brain regions, but this ignores the fact that TMS may affect network-level rather than nodal-level processes. We examine the effects of a double perturbation to two frontoparietal network nodes, compared with the effects of single lesions to either node. We hypothesized that Bayesian evidence for the absence of effects that build upon one another indicates that a single perturbation is consequential to network-level processes. Twenty-three humans performed pro-saccades (look toward) and anti-saccades (look away) after receiving continuous theta-burst stimulation (cTBS) to right frontal eye fields (FEFs), dorsolateral prefrontal cortex (DLPFC), or somatosensory cortex (S1; the control region). On a subset of trials, a TMS pulse was applied to right posterior parietal cortex (PPC). FEF, DLPFC, and PPC are important frontoparietal network nodes for generating anti-saccades. Bayesianttests were used to test hypotheses for enhanced double perturbation effects (cTBS plus TMS pulse) on saccade behaviors, against the alternative hypothesis that double perturbation effects to a network are not greater than single perturbation effects. In one case, we observed strong evidence [Bayes factor (BF10) = 325] that PPC TMS following DLPFC cTBS enhanced impairments in ipsilateral anti-saccade amplitudes over DLPFC cTBS alone, and not over the effect of the PPC pulse alone (BF10= 0.75), suggesting that double perturbation effects do not augment one another. Rather, this suggests that computations are distributed across the network, and in some cases there can be compensation for cTBS perturbations.

AbstractLocalization of odors is essential to animal survival, and thus animals are adept at odor navigation. In natural conditions animals encounter odor sources in which odor is carried by air flow varying in complexity. We sought to identify potential minimalist strategies that can effectively be used for odor-based navigation and asses their performance in an increasingly chaotic environment. To do so, we compared mouse,in silicomodel, and Arduino-based robot odor-localization behavior in a standardized odor landscape. Mouse performance remains robust in the presence of increased complexity, showing a shift in strategy towards faster movement with increased environmental complexity. Implementing simple binaral and temporal models of tropotaxis and klinotaxis, anin silicomodel and Arduino robot, in the same environment as the mice, are equally successful in locating the odor source within a plume of low complexity. However, performance of these algorithms significantly drops when the chaotic nature of the plume is increased. Additionally, both algorithm-driven systems show more successful performance when using a strictly binaral model at a larger sensor separation distance and more successful performance when using a temporal and binaral model when using a smaller sensor separation distance. This suggests that with an increasingly chaotic odor environment, mice rely on complex strategies that allow for robust odor localization that cannot be resolved by minimal algorithms that display robust performance at low levels of complexity. Thus, highlighting that an animal’s ability to modulate behavior with environmental complexity is beneficial for odor localization.
Another hijack! Some enteroviruses co‐opt the c10orf76/PI4KB complex for their own good
Authors: Voilquin Laetitia , Di Mattia Thomas , Alpy Fabien 
Published: January 2020

Enteroviruses, members of the Picornaviridae family, are non‐enveloped and single‐stranded RNA viruses responsible for several human diseases. During infection, these viruses build membrane‐bound organelles, called replication organelles (ROs), where new virions are assembled. ROs are highly enriched in phosphatidylinositol 4‐phosphate (PI4P) produced by the host lipid kinase PI4KB. In this issue of EMBO Reports, McPhail et al [1] characterize a complex, formed by PI4KB and the c10orf76 protein, which is involved in PI4P production. They show that this machinery is hijacked by specific enteroviruses such as coxsackievirus A10 for their replication.
