description: This paper is devoted to the Standard Model cross-sections for the production of single top, top quark in pairs, triple-top quarks, and four top-quarks at three different centre of mass-energies e.g., $\sqrt{s}=$7, 10 and 14 TeV at existing particle colliders as well as at Future Hadron Colliders. A fully kinemtaic analysis with the optimized pre-selection cuts along with invariant mass reconstruction of top quarks is performed for triple-top production processes pp$\rightarrow $tttW, tttd,tttb in the presence of Standard Model background. The three signal processes are forced to decay in fully hadronic mode and their significance is computed in High Luminosity Large Hadron Collider (HL$-$LHC) at $\sqrt{s}=$14 TeV and also in High-Energy LHC (HE$-$LHC) at $\sqrt{s}=$27 TeV. It is found that the observability at HL$-$LHC will would not be so easy task and chances are much lower but there are higher chances to observe the signal events at HE$-$LHC. The signal to background ratio and signal significance of all signal and background processes are estimated for both the HL$-$LHC and the HE$-$LHC at $\sqrt{s}$ =14 TeV and $\sqrt{s}$ =27 TeV respectively.

description: Previous studies have recorded 26 non-native and 14 cryptogenic species from the Stour and Orwell estuaries. Here we present data for an additional 11 non-native and 22 cryptogenic species, to give a total of 73 (37 non-native, 36 cryptogenic) now known from the area. Of these, six are newly reported from the United Kingdom (2 non-native: Eteone lighti, Melita nitida; 4 cryptogenic: Protocirrineris purgamentorum, Tharyx robustus, T. maryae, Tubificoides galiciensis). Eteone lighti is reported outside of its native range for the first time. Nine of the species are rated as High Impact under the Water Framework Directive (WFD) and thirteen are listed in the UK Marine Non-Indigenous Species Priority Species List. The records have been collated from a variety of routine monitoring surveys and environmental impact studies, as well as literature records, and demonstrate that a wide variety of sampling types is required to provide a comprehensive account of non-native species. Most of the non-native species have a native range in the North Pacific (38%) but many (27%) were from the north-west Atlantic; other native ranges were less well represented. Arthropods, particularly crustaceans, were the most represented phylum for non-native species. The number of cryptogenic species, especially amongst the annelids, illustrates knowledge gaps in our native fauna and that further understanding is required to establish how much of the fauna is genuinely native. In comparison with other available synopses of data, the findings presented here would suggest the study area to be one of the most invaded regions in Europe, although comparative studies are sparse. To establish baselines, determine introduction rates and assess the effectiveness of biosecurity measures under the WFD or Marine Strategy Framework Directive (MSFD) will require increased monitoring of key introduction hotspots and more comprehensive local reviews of non-native species.

description: Specimens of the brittle star genus Ophioderma were found at the South-West Atlantic coast of France. They were sampled between 2 and 40 m depth. Morphologically, these specimens were most similar to O. longicaudum and O. hybridum. Molecular analysis for a mitochondrial marker (COI) and nuclear marker EF1 sequences from twelve specimens showed that only O. longicaudum was present in this study, with a higher morphological variability than previously described. They represent the northernmost confirmed record for this species, yet.

It is proved that such $T_1$-topology is sequentially pracompact if and only if it is feebly compact. Also, we show that every shift-continuous feebly $ω$-bounded $T_1$-topology on $\mathscr{I}_λ^n$ is compact.

description: The Wilms' tumor suppressor gene, WT1, encodes a zinc finger transcription factor that has been demonstrated to negatively regulate several growth factor and cognate receptor genes. However, inconsistent with its tumor suppressor function, WT1 has also been demonstrated to be required to inhibit programmed cell death in vitro and in vivo. Moreover, anaplastic Wilms' tumors, which typically express wild-type WT1, display extreme resistance to chemotherapeutic agents that kill tumor cells through the induction of apoptosis. Although p53 mutations in anaplastic Wilms' tumors have been associated with chemoresistance, this event is believed to occur late during tumor progression. Therefore, since dysregulated WT1 expression occurs relatively early in Wilms' tumors, we hypothesized that WT1 was required to transcriptionally upregulate genes that provide a cell survival advantage to tumor cells. Here we demonstrate that sporadic Wilms' tumors coexpress WT1 and the anti-apoptotic Bcl-2 protein. Using rhabdoid cell lines overexpressing WT1, we show that WT1 activates the endogenous bcl-2 gene through a transcriptional mechanism. Transient transfections and electromobility shift assays demonstrate that WT1 positively stimulates the bcl-2 promoter through a direct interaction. Moreover, WT1 expressing cells displaying upregulated Bcl-2 were found to be resistant to apoptosis induced by staurosporine, vincristine and doxorubicine. These data suggest that in certain cellular contexts, WT1 exhibits oncogenic potential through the transcriptional upregulation of anti-apoptotic genes such as bcl-2.

description: In the present paper, the authors report the capture of two large specimens of roundfail stingray Taeniurops grabatus (Geoffroy Saint-Hilaire, 1817) from the Syrian coast, which exhibited an abnormal body coloration. The first specimen was a female which was measured 1290 mm in disc width (DW) and reached 86 kg for total body weight (TWB). This specimen was entirely unpigmented, whitish, with red eyes and displayed a total albinism. The second specimen was also a female measuring 1620 mm DW, 1530 mm disc length, and 2740 mm in total length, its TWB was 101 kg. The dorsal and ventral surfaces of this specimen were whitish, with a normal retinal coloration and the tail was entirely darkish. It displayed a case of partial albinism or leucism. They are the first cases of abnormal coloration recorded to date in elasmobranch species captured in the Syrian marine waters.

description: This paper presents an online system that leverages social media data in real time to identify landslide-related information automatically using state-of-the-art artificial intelligence techniques. The designed system can (i) reduce the information overload by eliminating duplicate and irrelevant content, (ii) identify landslide images, (iii) infer geolocation of the images, and (iv) categorize the user type (organization or person) of the account sharing the information. The system was deployed in February 2020 online at https://landslide-aidr.qcri.org/landslide_system.php to monitor live Twitter data stream and has been running continuously since then to provide time-critical information to partners such as British Geological Survey and European Mediterranean Seismological Centre. We trust this system can both contribute to harvesting of global landslide data for further research and support global landslide maps to facilitate emergency response and decision making.

description: This study presents the applications of the flipped classroom model (JITT) as an emergent didactic strategy with two groups of students in Childhood Teaching Degree, using the methodology of collaborative learning, where the professor implemented the flipped classroom model in one of the groups. From a quasi-experimental design, a total of 152 students participated on it. After applying the model to one of the groups, the student presented positive scores in the flipped classroom group. The students from the experimental group completed an open survey –online- before the implementation of the flipped classroom model and another one at the end of it to organise and follow the on-site sessions. The conclusions of the study based on the designed instruments showed progress regarding the use of collaborative learning in both groups, appearing particularly more valued in the flipped classroom group. In reference to the implementation of the model teachers´amount of work and students´ effort are highlighted, underlining the increase of students’ competence in the obtained average score.

description: Locus of Control is a specific mode in which each individual identifies the causes that determine an event and therefore their own successes and failures. The internal attribution style is based on the subject's ability, commitment, and intelligence. It strengthens self-esteem and sense of personal self-efficacy and is crucial to fostering school success. This research shows that an attributive-metacognitive training that offers students the opportunity to reflect on their skills and strategies by expanding motivation through information and communication technologies (ICTs) can improve the attributional style of students with SEN (Special Educational Needs). The study, prospective and longitudinal, measured the attribution style of attendees (30 subjects attending the first grade of secondary school in northeast Italy) before and after a metacognitive and attributive program. The training, carried out on-line and in attendance, lasted about 8 months (from April 2015 to November 2015). The article presents the positive outcomes of the training, supported by the comparison of the data emerging from the Attribution Questionnaire and regularized and standardized values ​​(De Beni e Moè, 1995). The presented study extends knowledge on approaches and programs aimed at improving the attributional style in children with Special Educational Needs. A progress of the internal attributional style is conducive to improving academic success in these subjects.

description: Bacterial endosymbionts evolve under strong host-driven selection. Factors influencing host evolution might affect symbionts in similar ways, potentially leading to correlations between the molecular evolutionary rates of hosts and symbionts. Although there is evidence of rate correlations between mitochondrial and nuclear genes, similar investigations of hosts and symbionts are lacking. Here, we demonstrate a correlation in molecular rates between the genomes of an endosymbiont (Blattabacterium cuenoti) and the mitochondrial genomes of their hosts (cockroaches). We used partial genome data for multiple strains of B. cuenoti to compare phylogenetic relationships and evolutionary rates for 55 cockroach/symbiont pairs. The phylogenies inferred for B. cuenoti and the mitochondrial genomes of their hosts were largely congruent, as expected from their identical maternal and cytoplasmic mode of inheritance. We found a correlation between evolutionary rates of the two genomes, based on comparisons of root-to-tip distances and on comparisons of the branch lengths of phylogenetically independent species pairs. Our results underscore the profound effects that long-term symbiosis can have on the biology of each symbiotic partner.

description: We use data from the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey to study how the spatial variation in the stellar populations of galaxies relate to the formation of galaxies at $1.5 < z < 3.5$. We use the Internal Color Dispersion (ICD), measured between the rest-frame UV and optical bands, which is sensitive to age (and dust attenuation) variations in stellar populations. The ICD shows a relation with the stellar masses and morphologies of the galaxies. Galaxies with the largest variation in their stellar populations as evidenced by high ICD have disk-dominated morphologies (with Sérsic indexes $< 2$) and stellar masses between $10 < \mathrm{Log~M/ M_\odot}< 11$. There is a marked decrease in the ICD as the stellar mass and/or the Sérsic index increases. By studying the relations between the ICD and other galaxy properties including sizes, total colors, star-formation rate, and dust attenuation, we conclude that the largest variations in stellar populations occur in galaxies where the light from newly, high star-forming clumps contrasts older stellar disk populations. This phase reaches a peak for galaxies only with a specific stellar mass range, $10 < \mathrm{Log~M/ M_\odot} < 11$, and prior to the formation of a substantial bulge/spheroid. In contrast, galaxies at higher or lower stellar masses, and/or higher Sérsic index ($n > 2$) show reduced ICD values, implying a greater homogeneity of their stellar populations. This indicates that if a galaxy is to have both a quiescent bulge along with a star forming disk, typical of Hubble Sequence galaxies, this is most common for stellar masses $10 < \mathrm{Log~M/M_\odot} < 11$ and when the bulge component remains relatively small ($n<2$).

Subjects: AI regulation; AI ethics; innovation; consumer protection; game theory

description: In response to the rapid development of AI, several governments have established a variety of regulatory interventions for this technology. While some countries prioritize consumer protection through stringent regulation, others promote innovation by adopting a more hands-off approach. However, this tradeoff has not been analyzed systematically. We developed an economic theory on how the welfare-maximizing level of regulatory stringency for AI depends on various institutional parameters. Our game-theoretic model is motivated and built upon the comparison of regulatory documents for AI from the EU, the UK, the US, Russia, and China. The results show that if a government strives to find the right balance between innovation and consumer protection to maximize actual consumer welfare, stringent regulation is optimal when foreign competition is either high or low, whereas light-touch regulation is optimal when foreign competition is intermediate. Meanwhile, minimal regulation is rationalizable only if a government prioritizes other objectives in its agenda, such as maximizing innovation, domestic producer surplus, or perceived consumer welfare.

description: Tide pools are common in the intertidal regions. They show high heterogeneity regarding their inherent characteristics and associated communities. Epifaunal tide pool communities have been overlooked in coastal studies. Here, we describe the epifaunal macroinvertebrate communities of six tide pools dominated by Cystoseira humilis on northwest coast of Tenerife (Canary Islands) and attempt to unravel the variability of these habitats to determine the effect of different variables on these communities. The epifaunal community in the studied tide pools comprised 74 species, mostly mollusks (24 species), annelids (23 species), and crustaceans (18 species). In terms of epifaunal richness and algal coverage the tide pools exhibited a parallel trend. The same tide pools boasting higher species richness also display high algal coverage, with both variables declining in the same order along the different tide pools. Tide pools with a high human presence showed the highest abundance, species richness, and algal coverage. A statistically significant effect of human presence and algal cover on the tidepool epifaunal community was observed. Unfortunately, the variability remained too high to unravel the effects of different variables on the epifaunal invertebrate community.

description: The superconducting state of the newly discovered superconductor K$_2$Cr$_3$As$_3$ with a quasi-one-dimensional crystal structure ($T_{\bf c}\sim$ 6 K) has been investigated by using magnetization and muon-spin relaxation or rotation ($μ$SR) measurements. Our analysis of the temperature dependence of the superfluid density obtained from the transverse field (TF) $μ$SR measurements fit very well to an isotropic $s$-wave character for the superconducting gap. Furthermore a similarly good fit can also be obtained using a $d$-wave model with line nodes. Our zero-field $μ$SR measurements do reveal very weak evidence of the spontaneous appearance of an internal magnetic field near the transition temperature, which might indicate that the superconducting state is not conventional. This observation suggests that the electrons are paired via unconventional channels such as spin fluctuations, as proposed on the basis of theoretical models of K$_2$Cr$_3$As$_3$. Furthermore, from our TF $μ$SR study the magnetic penetration depth $λ_L$, superconducting carrier density $n_s$, and effective-mass enhancement $m^*$ have been estimated to be $λ_L(0)$ = 454(4) nm, $n_s$ = 2.4$\times$10$^{27}$ carriers/m$^3$, and $m^*$ = 1.75 $m_e$, respectively.

description: We present a new approach for universal texture synthesis by incorporating a multi-scale texton broadcasting module in the StyleGAN-2 framework. The texton broadcasting module introduces an inductive bias, enabling generation of broader range of textures, from those with regular structures to completely stochastic ones. To train and evaluate the proposed approach, we construct a comprehensive high-resolution dataset that captures the diversity of natural textures as well as stochastic variations within each perceptually uniform texture. Experimental results demonstrate that the proposed approach yields significantly better quality textures than the state of the art. The ultimate goal of this work is a comprehensive understanding of texture space.

description: The relationships between otolith measurements and fish length (total length) and total weight in five Sillaginid species, Sillago arabica, Sillago attenuata, Sillago indica, Sillago sihama and Sillaginopodys chondropus, are estimated. Results revealed a strong correlation between otolith measurements and fish length and weight in all five species (p < 0.05; R2 from 0.76 to 0.95). Comparing relative otolith size within species, S. chondropus otoliths were smaller than those of other Sillaginid species. The strongest relationships appeared between otolith weight (OWE) and fish length in S. arabica and S. chondropus (R2 = 0.93 and 0.95, respectively), while otolith length was most strongly related to fish length in the other three species (R2 = 0.83 - 0.92). Results showed that body size estimation through analyses of otoliths size is reliable for the five studied Sillaginid species, and the provided data could be useful baseline information for further biological, ecological and stock assessment studies of Sillaginid species in the Persian Gulf and the Oman Sea.

description: In the canonical theory of stellar magnetic dynamo, the tachocline in partially convective stars serves to arrange small-scale fields, generated by stochastic movement of plasma into a coherent large-scale field. Mid-to-late M-dwarfs, which are fully convective, show more magnetic activity than classical magnetic dymano theory predicts. However, mid-to-late M-dwarfs show tight correlations between rotation and magnetic activity, consistent with elements of classical dynamo theory. We use data from Magellan Inamori Kyocera Echelle (MIKE) Spectrograph to detail the relation between Ca II H\&K flux and rotation period for these low-mass stars. We measure $R'_{HK}$ values for 53 spectroscopically identified M-dwarfs selected from the MEarth survey; these stars span spectral classes from M5.0 to M3.5 and have rotation periods ranging from hours to months. We present the rotation--activity relationship as traced through these data. We find power law and saturated regimes consistent to within one sigma of previously published results and observe a mass dependence in $R'_{HK}$.

description: Analysis of mRNA levels in cells that express or lack signal transducers and activators of transcription 1 (Stat1) reveals that Stat1 mediates the constitutive transcription of many genes. Expression of the low molecular mass polypeptide 2 (LMP2), which requires Stat1, has been studied in detail. The overlapping interferon consensus sequence 2/γ-interferon-activated sequence (ICS-2/GAS) elements in the LMP2 promoter bind to interferon regulatory factor 1 (IRF1) and Stat1 and are occupied constitutively in vivo. The point mutant of Stat1, Y701F, which does not form dimers involving SH2–phosphotyrosine interactions, binds to the GAS element and supports LMP2 expression. Unphosphorylated Stat1 binds to IRF1 directly and we conclude that this complex uses the ICS-2/GAS element to mediate constitutive LMP2 transcription in vivo. The promoter of the IRF1 gene, which also contains a GAS site but not an adjacent ICS-2 site, is not activated by Stat1 Y701F. The promoters of other genes whose constitutive expression requires Stat1 may also utilize complexes of unphosphorylated Stat1 with IRF1 or other transcription factors.

description: We analyze the harvesting of entanglement and classical correlations from the quantum vacuum to particle detectors. We assess the impact on the detectors' harvesting ability of the spacetime dimensionality, the suddenness of the detectors' switching, their physical size and their internal energy structure. Our study reveals several interesting dependences on these parameters that can be used to optimize the harvesting of classical and quantum correlations. Furthermore, we find that, contrary to previous belief, smooth switching is much more efficient than sudden switching in order to harvest vacuum entanglement, especially when the detectors remain spacelike separated. Additionally, we show that the reported phenomenology of spacelike entanglement harvesting is not altered by subleading order perturbative corrections.

description: This study focused on the phylogenetics and species identification of Scylla specimens collected from several coasts of Indonesia. Seventeen specimens of mud crabs were collected from six different locations on four different islands: Java, Sulawesi, Ambon, and Papua. For phylogenetic analysis, we used maximum likelihood (ML) tree construction, pairwise Kimura 2-Parameter (K2P) sequence divergence comparison, and curated sequences from all Scylla members in Genbank. DNA sequences were used to generate a haplotype network for this study. COI sequence lengths in 17 samples varied from 629 to 701 bp, and a 519 bp length homologous nucleotide alignment was selected for further investigation, presenting 110 segregating sites. The ML tree structure was similar to tree topology from previous investigations. Ten haplotypes were formed through a network of haplotypes between COI sequences. With 17 crab specimens, our research revealed for the first time that the four geographic species of the genus Scylla occupy the coastal waters of the Indonesian archipelago.

description: The Saccharomyces cerevisiae origin recognition complex (ORC) is bound to origins of DNA replication throughout the cell cycle and directs the assembly of higher-order protein–DNA complexes during G1. To examine the fate of ORC when origin DNA is unwound during replication initiation, we determined the effect of single-stranded DNA (ssDNA) on ORC. We show that ORC can bind ssDNA and that ORC bound to ssDNA is distinct from that bound to double-stranded origin DNA. ssDNA stimulated ORC ATPase activity, whereas double-stranded origin DNA inhibited the same activity. Electron microscopy studies revealed two alternative conformations of ORC: an extended conformation stabilized by origin DNA and a bent conformation stabilized by ssDNA. Therefore, ORC appears to exist in two distinct states with respect to its conformation and ATPase activity. Interestingly, the effect of ssDNA on these properties of ORC is correlated with ssDNA length. Since double-stranded origin DNA and ssDNA differentially stabilize these two forms of ORC, we propose that origin unwinding triggers a transition between these alternative states.

description: The present paper describes one of the pilot activities foreseen by the Erasmus+ project DICHE (Digital Innovation in Cultural and Heritage Education in the light of 21st century learning). The above mentioned pilot activity was carried out at the undergraduate course in Educational sciences – University AUTHOR, as an internal training module for the conception, implementation and evaluation of MOOC courses in museum education. Main objective of the module was to develop design and realisation skills in Educational science students. Those engaged in the module were asked to create cultural and heritage education courses for primary school in training and in service teachers. The two main pillars of the DICHE pilot, “MOOCs conception and delivery” and “heritage education”, are in line with the most recent national and international field literature research and with the Italian education system directions, aiming at integrating museum education in primary school curricula and a more aware use of technology, in order to develop pivotal skills in active citizenship building. The present paper presents the methodology adopted and the results collected during the training module carried out.

MOOCs and Soft Skills: a comparison of different courses on Creativity

description: The development of soft skills in undergraduate students is a key factor to ensure an effective transition from university to the labour market. The eLene4work project, carried out between 2014 and 2017, focused on the selection and definition of these soft skills, including digital soft skills. The project proposes a series of actions and practical tools to help students better understand the employers’ expectations, to assess their own level of competency and to develop their skills through MOOCs (Massive Open Online Courses) and OERs (Open Educational Resources). The overall goal of the project is to test and monitor the possibilities offered by these resources to fill the gaps between the university and the labour market. It might seem quite challenging to develop soft skills through online resources since these skills are mainly behavioural components. One of the main outputs of the project consisted in designing an Orientation Guide for students and young workers, to help them in choosing and effectively using MOOCs to train soft skills and digital soft skills. This paper reports the results of the work carried out by the project partners during MOOCs selection and classification. Furthermore, the comparison of different MOOCs on creativity, based on distinctive pedagogical approaches and involving different types of activities and assessment tools, highlights some important trends in the ways used to foster students’ learning behaviours and different patterns of engagement.

description: In Drosophila, phototransduction is mediated by Gq-activation of phospholipase C and is a well studied model system for understanding the kinetics of signal initiation, propagation and termination controlled by G proteins. The proper intracellular targeting and spatial arrangement of most proteins involved in fly phototransduction require the multi-domain scaffolding protein InaD, composed almost entirely of five PDZ domains, which independently bind various proteins including NorpA, the relevant phospho lipase C-β isozyme. We have determined the crystal structure of the N-terminal PDZ domain of InaD bound to a peptide corresponding to the C-terminus of NorpA to 1.8 Å resolution. The structure highlights an intermolecular disulfide bond necessary for high affinity interaction as determined by both in vitro and in vivo studies. Since other proteins also possess similar, cysteine-containing consensus sequences for binding PDZ domains, this disulfide-mediated ‘dock-and-lock’ interaction of PDZ domains with their ligands may be a relatively ubiquitous mode of coordinating signaling pathways.

description: A new generalization of the Hawking-Hayward quasilocal energy to scalar-tensor gravity is proposed without assuming symmetries, asymptotic flatness, or special spacetime metrics. The procedure followed is simple but powerful and consists of writing the scalar-tensor field equations as effective Einstein equations and then applying the standard definition of quasilocal mass.
