Authors: Gellesch Markus , Jones Jonathan , Barron Richard , Singh Alok , Sun Qiushuo , Bongs Kai , Singh Yeshpal 
Published: October 2020

Abstract
Recently, several reports with a strong focus on compact, nonstationary optical atomic clocks have been published, including accounts of in-field deployment of these devices for demonstrations of chronometric levelling in different types of environments. We review recent progress in this research area, comprising compact and transportable neutral atom and single-ion optical atomic clocks. The identified transportable optical clocks strive for low volume, weight and power consumption while exceeding standard microwave atomic clocks in fractional frequency instability and systematic uncertainty. Some transportable clock projects additionally address requirements for metrology or serve the joint technology development between industrial and academic stakeholders. Based on the reviewed reports on nonstationary optical atomic clocks, we suggest definitions for transportable, portable and mobile optical atomic clocks. We conclude our article with an overview of possible future directions for developments of optical clock technology.
Young children as actors of institutional language policies and practices in day care centres
Authors: Simoes Lourêiro Kevin , Neumann Sascha 
Published: October 2020

AbstractAs children’s agency in influencing institutional language practices is often not carefully reflected in early childhood education curricula, the objective of this paper is to offer meaningful insights about how institutional language policies are both reproduced and transformed by children’s everyday use of language. For this purpose, we will combine conceptual resources from social theory, sociolinguistics and childhood studies in order to analyse children’s linguistic behaviour by applying a structure-agency perspective as a relational approach. Drawing on data from ethnographic field research within institutional day care centres in Luxembourg, our findings demonstrate that the status of children as actors in institutional language practices is strongly connected to institutional policies as a structural condition. However, this does not mean that children just enact these language policies, because they are actors of both maintaining, underminingandalternating them. In this respect, especially the translanguaging of children and caregivers plays a crucial role in the Luxembourgish context as it allows to build a bridge between the official institutional language policy and the individual linguistic repertoires. Considering the goal of establishing a plurilingual environment in early childhood education which now is paramount to the educational language policy of the Luxembourgish government, this article suggests that translanguaging practices should be considered as one of the key starting points to create a plurilingual ecology in and through everyday practice in the day care centres.
The geometric sieve for quadrics
Authors: Browning Tim D. , Heath-Brown Roger 
Published: October 2020

Abstract
We develop a version of Ekedahl’s geometric sieve for integral quadratic forms of rank at least five. As one ranges over the zeros of such quadratic forms, we use the sieve to compute the density of coprime values of polynomials, and furthermore, to address a question about local solubility in families of varieties
parameterised by the zeros.
An Alternative to Data Ownership: Managing Access to Non-Personal Data through the Commons
Authors: Fia Tommaso 
Published: October 2020

Abstract
In today’s algorithmic society, access to large-scale datasets is the sine qua non for any economic actor to reap the benefits of data-driven innovation (DDI). This article explores alternative mechanisms of data management in large-scale processing environments which can bolster access in view of the shortcomings of the existing data ownership-centric system. The scope of the analysis is limited to non-personal data. First, this contribution elaborates on the features and shortcomings of the data ownership-centric system and the existing legislation on data access. In fact, despite its ground-breaking potential, data access is not a widely available resource. It is subject, meanwhile, to the ability of several actors to control it, originating from data holders’ position of de facto control over data (“data ownership”), which is mostly anchored in technological, behavioural, and legal access barriers. This ownership-oriented setting thus stifles data sharing and opportunities for novel reuses of data. Despite these concerns, EU secondary legislation and case law (including the “essential facilities doctrine” of competition law) have not yet offered appropriate means to enable data access across society. Second, this article investigates whether alternative systems of data management based on the commons is a viable solution to open up access to raw non-personal data (RNPD). The commons as a conceptual notion and institutional mechanism values access and freedom to operate, instead of power to appropriate. The article homes in on two main reasons which substantiate why commons management of RNPD can be desirable. On the one hand, RNPD can be deemed a cooperative infrastructural resource that calls for being pulled out of its factual enclosure (“structuralist approach” of the commons). On the other hand, grasping RNPD as a commons means valuing its functional nature, making data available to a wide number of actors for the fulfilment of fundamental rights and enhancing human flourishing (“functionalist approach”). The article concludes with some thoughts on the lines of research which are still to be explored to put the commons-based vision of data management into practice.
Using the generalized Adams-Bashforth-Moulton method for obtaining the numerical solution of some variable-order fractional dynamical models
Authors: Khader Mohamed M. 
Published: October 2020

Abstract
This paper is devoted to introduce a numerical treatment using the generalized Adams-Bashforth-Moulton method for some of the variable-order fractional modeling dynamics problems, such as Riccati and Logistic differential equations. The fractional derivative is described in Caputo variable-order fractional sense. The obtained numerical results of the proposed models show the simplicity and efficiency of the proposed method. Moreover, the convergence order of the method is also estimated numerically.

Published: October 2020

Abstract

Objectives
Prevalence of Maternal and congenital hypothyroidism is on the rise. To present the thyroid stimulating hormone screening results in babies born to hypothyroid mothers and assess the burden, aetiology of hypothyroidism in these babies

Methods
All antenatal mothers attending our hospital during the study period were enrolled into the study. Group I includes 249 term babies born to hypothyroid mothers and group II comprises 2154 newborns born to mothers who are euthyroid. Heel prick thyroid stimulating hormone was done for all newborns on day 3 for both groups. Confirmatory venous testing was done for all for babies in group I and screen positives belonging to group II. Evaluation and therapy done as per standard guidelines.

Results
Thyroid stimulating hormone values in the two groups are presented. There was significant correlation between peak maternal thyroid stimulating hormone and neonatal day 3 heel prick in group I (r=0.7, P<0.05). The prevalence of positive screening test in groups I and II was 3.8 and 1.03% (p<0.05) whereas corresponding values for confirmed disease was 4.3 and 0.6%, respectively (p<0.05). Aetiological evaluation revealed both transient hypothyroidism (33.3%) and permanent hypothyroidism (66.6%).

Conclusion
4.3% of babies born to hypothyroid mothers develop congenital hypothyroidism; aetiology being both transient and permanent. A venous test by 3 weeks is helpful in these babies to improve case identification.
Fast laser speckle suppression with an intracavity diffuser
Authors: Mahler Simon , Eliezer Yaniv , Yılmaz Hasan , Friesem Asher A. , Davidson Nir , Cao Hui 
Published: October 2020

AbstractFast speckle suppression is crucial for time-resolved full-field imaging with laser illumination. Here, we introduce a method to accelerate the spatial decoherence of laser emission, achieving speckle suppression in the nanosecond integration time scale. The method relies on the insertion of an intracavity phase diffuser into a degenerate cavity laser to break the frequency degeneracy of transverse modes and broaden the lasing spectrum. The ultrafast decoherence of laser emission results in the reduction of speckle contrast to 3% in less than 1 ns.
Herbert Spencer: A Case History of Nietzsche’s Conception of Decadence
Authors: Hurrell David 
Published: October 2020

AbstractNietzsche characterises some influential individuals – such as Socrates and Wagner – as “decadents” because they promote life-inhibiting values that potentially undermine the flourishing of humanity. A clearly stated but less prominent example of such a decadent is Herbert Spencer. While Nietzsche’s observations concerning Spencer are far fewer than those on Socrates and Wagner, they still have considerably significance for understanding Nietzsche’s philosophy – particularly his views on morality and science – and consequently their role in his conception of decadence. This article argues that Nietzsche considers Spencer to be a decadent not just because of the latter’s advocating of a morality based on altruism, but also the projection of the decadent values of this morality as inevitable, as part of his belief in objective, scientific and sociological truths.

Published: October 2020

AbstractThe books I review are a series of three volumes of the same project,Nietzsche’s Engagements with Kant and the Kantian Legacy, edited in 2017 by Marco Brusotti, Herman Siemens, João Constâncio, Tom Bailey, Maria João Mayer Branco and Katia Hay who seek to situate Nietzsche’s work in relation to Kant and Kantianism and to interpret it from this perspective. This review consists of two parts: the first part reviews and discusses each of the works focusing on a selection of prominent chapters; the second part extends their intuitions.
Zn(II)-selective poly (vinyl chloride) (PVC) membrane electrode based on Schiff base ligand 2-benzoylpyridine semicarbazone as an ionophore
Authors: Suman Shankar , Singh Ram 
Published: October 2020

Abstract
A new poly (vinyl chloride) (PVC) membrane electrode using 2-benzoylpyridine semicarbazone as membrane carrier with dioctylphthalate as plasticizer and sodium tetraphenylborate (NaTBP) as anion excluder has been fabricated and investigated as Zn(II)-selective electrode. Best potential response is observed for the composition PVC 30%, plasticizer 58%, NaTBP 8% and ionophore 4% (w/w). The sensor showed a linear stable response over a concentration range of 1.0 × 10−2–4.56 × 10−6 M with a detection limit of 2.28 × 10−6 M and a response time <10 s. The electrode can be used for at least six months without any divergence in potential.

Published: October 2020

Abstract

Objectives
Breast cancer (BC) is the most commonly diagnosed cancer in women worldwide with a high mortality rate, despite early detection and treatment. Spindle and kinetochore-associated complex subunit 3 (SKA3) is closely correlated with patient outcomes in several cancers. The present study aimed to elucidate the role of SKA3 in BC.

Methods
The biological functions of SKA3 was investigated by proliferation and migration assays in MDA-MB-231 cells with stable SKA3 knockdown and Hs578T cells ectopically expressing SKA3. Gene Expression Omnibus datasets were utilised to determine the correlation between SKA3 expression and clinical features of BC patients.

Results
We confirmed that SKA3 mRNA expression is higher in breast tumour tissue than in normal tissue, and that higher SKA3 expression is associated with poor survival rate of BC patients. Knockdown of SKA3 reduced MDA-MB-231 cell proliferation and migration, whereas SKA3 overexpression enhanced the proliferative and migratory ability of Hs578T cells. We also found that SKA3 is involved in regulating cell cycle progression in mitotic exit.

Conclusions
These results suggest that SKA3 is correlated with BC cell proliferation and migration by promoting cell cycle progression, and could be a novel potential therapeutic target for BC treatment.
Spanish quepo: the untold story
Authors: Rini Joel 
Published: October 2020

Abstract
The pres. ind. paradigm of Sp. caber ‘to fit’ exhibits a synchronically irregular form in the 1st pers. sg., i.e., quepo, instead of a synchronically regular form derived from the infinitive, i.e., caber → *cabo. However, quepo is not considered at all historically irregular. Since the first historical grammar of Spanish, quepo has been understood to be a direct continuation of Lat. capiō, which apparently evolved through regular phonetic development, like pres. subj. capiam > quepa, sapiam > sepa. Nonetheless, one may question why quepo has not been replaced by *cabo in Modern Spanish given its extremely low frequency of occurrence, as forms of a language that occur infrequently are often regularized. A historical look at quepo reveals the following surprising facts: (1) Although pres. subj. quepa is attested from the earliest Old Spanish texts onward, quepo is absent from the written record throughout the Old and Medieval Spanish periods and does not appear until the end of the sixteenth century; (2) Regularized cabo served as the first person singular of the present indicative until then. The present study attempts to explain through well-established processes of historical morphology the late appearance of quepo and its continued existence in Modern Spanish.
La introducción del anglicismo berry/berries en el español de Chile: historia, proceso integrativo y consecuencias semánticas
Authors: Sinner Carsten , Salas Constanza Gerding 
Published: October 2020

Abstract
Lexical innovation is a continuous creative phenomenon which evinces language vitality. In today’s Spanish, borrowing words from other languages is a fruitful innovation mechanism. In Chilean Spanish, a significant portion of lexical neology comes from English loanwords, a fact that may be attributed in part to the global, open-market model upon which the country bases its economy. In this context and because of its linguistic and cultural relevance, we established the development process of the English loanword berry/berries in Chilean Spanish. To this end, this paper presents an analysis of the sociohistorical background that gave rise to the introduction of this Anglicism in Chile. This mixed-methods research includes the analysis of texts, interviews, surveys and field study. A contrastive lexicographic description of berry and its equivalents in Spanish is provided, the role of different types of speakers —from experts to laypeople— is analyzed in relation to the incorporation of this neologism in Chilean Spanish, the occurrence of different existing denominations is examined, some neologicity indicators are analyzed, possible combinations of berry/berries with other elements are classified, and the evolution of this Anglicism in Chilean Spanish use is confirmed.
Cancioneros manuscritos y mise en texte
Authors: González Déborah 
Published: October 2020

Abstract
Galician-Portuguese troubadours were able to bring their compositions to a close by means of one or a series of fiindas. The fiinda can be understood as a conclusive sequence, shorter than a cobra or stanza, which is harmoniously integrated into the composition in terms of both form and content. The principles governing the textual arrangement of the various Galician-Portuguese manuscript songbooks (the medieval A, fragmentary and unfinished, and the Italian apographs B and V of the humanist period) are of considerable help in identifying these final segments in texts where they are present. However, vicissitudes in the transmission of some compositions with fiindas have occasionally led to a blurring or obscuring of these sequences, which in turn may have been an obstacle to the correct perception and identification of the textual structure of fiindas by editors of these texts.
The 9 November 2002 Earthquake in the Northeast of the Russian Plate (Komi Republic)
Authors: Noskova N.N. , Morozov A.N. , Vaganova N.V. 
Published: October 2020

Abstract
—The East European Platform (EEP) is characterized by a rather weak seismicity. The south of the Komi Republic is the most seismically active territory in the northeast of the EEP. The 1939 Sysola earthquake (grade 7), one of the strongest earthquakes in the European north of the 20th century, occurred there. Many world’s seismic stations recorded an earthquake in the Priluzsky region of the republic on 9 November 2002, but it was not thoroughly studied and is not considered in literature. In this work we recalculate the parameters of the earthquake hypocenter, substantiate its tectonic nature, construct its focal mechanism, and describe its tectonic position. For processing, we used data on 86 seismic phases from 58 stations with epicentral distances from 5.9 to 57°, azimuth angles from 1.5 to 341.7°, and the maximum azimuthal gap of 70°. The following parameters of the hypocenter were obtained: t0 = 06 h 47 min 17.9 s, 59.93° N, 49.76° E, Rminor = 7.7 km, Rmajor = 10.7 km, Azmajor = 20°, h = 16 km, and Ms = 3.4/5. The earthquake is localized in the upper crust and is confined to the zone of the junction of the eastern slope of the Sysola arch and the western flank of the Kirov–Kazhim aulacogen of the Volga–Ural anteclise of the Russian Plate. We have established a strike-slip fault focal mechanism of the earthquake, which corresponds to the latest stress field of the region. The estimated axis parameters (value, azimuth, plunge) are as follows: T = 0.707, 90.0, 0; N = 0, 0, 39.792; and P = –0.707, 180.0, 50.208. The plane parameters (strike, dip, slip) are estimated at 327, 57, –140° for the first plane and 213, 57, –40° for the second plane. The recorded seismic events in the northeast of the Russian Plate indicate that the platform area is not seismically passive. The performed research shows that recent seismotectonic processes are related to the structure and state of the Earth’s crust within the platform.
Regional Magnetostratigraphy of the Upper Cretaceous and the Cretaceous–Paleogene Boundary in Southern West Siberia as Applied to Complitation of the Cretaceous Magnetic-Polarity Scale
Authors: Gnibidenko Z.N. , Kuzmina O.B. , Levicheva A.V. 
Published: October 2020

Abstract
—Magnetostratigraphic data from wells in southern West Siberia that strip the Upper Cretaceous and Cretaceous–Paleogene boundary strata in three areas (three wells in the Omsk Basin, two wells in the Bakchar Iron Basin, and two wells in the southern Kulunda Basin) are used to compile the respective regional magnetic-polarity scale. According to the available biostratigraphic constraints, the deposition spanned the period from Albian to Bartonian. The reported regional polarity scale is based on integrated paleomagnetic and biostratigraphic data from the seven wells and comprises four Upper Cretaceous zones of normal (NK1-2(al-st) and NK2mt) and reverse (RK2km and RK2mt) polarity corresponding to the C34, C33r, C31r, and C30n Chrons of the global magnetic polarity scale and four Paleogene zones of reverse polarity: R1E1zl, R2E1t, R1E2t-i(?), and R1E2l-b, with the first two correlating with the C26r and C25r Chrons. Some of the Upper Cretaceous magnetozones enclose thin intervals (microzones) of the opposite polarity. The regional Cretaceous–Paleogene magnetic-polarity scale of southern West Siberia reveals several deposition gaps from 6 to 28 Myr long. The magnetostratigraphic data can be used to determine deposition rates and can make reference for local, regional, and global correlations of geologic events given that polarity reversals are of global extent.
A Physicochemical Model of Gold Transformation in the Wastes of Processed Pyrite–Polymetallic Ores (Salair Ridge, Russia)
Authors: Khusainova A.Sh. , Gaskova O.L. , Kalinin Yu.A. , Bortnikova S.B. 
Published: October 2020

Abstract
—Gold-bearing dumps of processed pyrite–polymetallic ores of the Ursk ore field (Novo-Urskoe and Beloklyuchevskoe deposits, Salair Ridge) have been studied. Physicochemical modeling of the gold behavior in wastes allowed us to describe quantitatively the gold precipitation process in different horizons of the dumps. In the upper part of the sulfide-rich section, sulfide minerals undergo intense oxidation accompanied by the dissolution of structural and surface-bound gold. Gold redeposition on the pyrite surface (sorption reduction barrier) as a result of electrochemical processes is accompanied by the formation of heavy-metal sulfates and barite. Under the sorption barrier, there is a loose leaching horizon with high humidity, where gold is present in pore solutions as thiosulfate, hydrosulfide, and hydroxo complexes; its content reaches 68 mg/L. In the middle part of the section, composed of compact siliceous sandstones (hardpan), high-grade (up to 973‰) gold forms through the disintegration of thiosulfate complexes, but its content decreases to 10-6 mg/L (lithologic reduction barrier). No visible gold was found in the lower part of the section (soil bed), but its high contents (up to 0.35–0.42 g/L) might be due to the sorption by organic high-molecular compounds, such as humic acids. The morphology and chemical composition of native gold from the gold-containing dumps of processed pyrite–polymetallic ores have been first studied. It is shown that the gold surface has traces of supergene transformations, e.g., gold nano- and microparticles as sponge overgrowth on the gold or barite particle surface or as newly formed gold phases in Fe, Mn, and Al hydroxide films.
Chlorine in the Earth’s Mantle as an Indicator of the Global Recycling of Oceanic Crust
Authors: Asafov E.V. , Sobolev A.V. , Batanova V.G. , Portnyagin M.V. 
Published: October 2020

Abstract
—Homogenized melt inclusions in olivine were studied in Archean komatiites from the Barberton Greenstone Belt, Weltevreden Formation in South Africa (3.3 Ga), Abitibi Greenstone Belt in Canada (2.72 Ga), and the Belingwe Greenstone Belt in Zimbabwe (2.69 Ga). Contamination of the komatiite melts with crustal material enriched in Rb, Cl, and H2O during the crystallization of olivine is demonstrated. Uncontaminated melts have mantle Rb/Nb ratios but are significantly enriched in Cl and H2O relative to K and Ce, respectively, exhibiting similar incompatibility during crystallization and partial mantle melting. These observations suggest the presence of a chlorine- and water-enriched mantle source before 3.3 Ga. The excess Cl and H2O contents in the komatiites are assumed to result from the interaction of partially molten mantle plumes with the mantle transition zone. The most likely source of Cl and H2O enriching the deep mantle is the oceanic lithosphere that endured a seafloor alteration. We conclude that the recycling of the altered oceanic lithosphere into the mantle, probably via subduction, began in the first billion years of the Earth’s history. Delamination of the Archean crust could not cause transport of chlorine and water into the deep mantle.
