description: The set theory relations \in, \backslash, Δ, \cap, and \cup have corollaries in subspace relations. Geometric Algebra is introduced as the ideal framework to explore these subspace operations. The relations \in, \backslash, and Δare easily subsumed by Geometric Algebra for Euclidean metrics. A short computation shows that the meet (\cap) and join (\cup) are resolved in a projection operator representation with the aid of one additional product beyond the standard Geometric Algebra products. The result is that the join can be computed even when the subspaces have a common factor, and the meet can be computed without knowing the join. All of the operations can be defined and computed in any signature (including degenerate signatures) by transforming the problem to an analogous problem in a different algebra through a transformation induced by a linear invertible function (a LIFT to a different algebra). The new results, as well as the techniques by which we reach them, add to the tools available for subspace computations.

description: The purpose of all free trade agreements is, among other things, to liberalize trade and increase market access. Mindful that requiring trade liberalization could result in damaging consequences among the participating countries that are at different levels of economic development, the U.S.–Arab countries free trade agreements (FTAs) include exceptions. These FTAs permit countries to depart “temporarily” from their obligations of liberalizing trade, and apply safeguard measures. This article surveys safeguard provisions on trade in goods in U.S.–Arab countries FTAs. In particular, the article identifies those FTAs that modify the conditions applicable to the partner either substantively or procedurally in the event that a global safeguard is invoked. In the case of bilateral safeguards, the article analyses provisions governing injury assessment and causation, conditions for the invocation of a measure, and the types of measures that may be employed. The article uses, whenever possible, the yardstick of GATT Article XIX and the WTO Safeguards Agreement to determine whether the provisions applicable to bilateral safeguard measures are more or less stringent than the corresponding multilateral rules. The article also examines the reference to infant industry and special safeguards applicable to textile and agricultural products found in these FTAs. The article concludes with a set of suggestions.

description: A major criterion for determining the eligibility of candidates for admission into Nigerian Universitieswas their performance in UTME and Post-UTME before the scrap of the Post-UTME in 2016. Thisstudy was therefore aimed at investigating the performance of students in UTME conducted byJoint Admissions and Matriculation Board (JAMB) and the Post-UTME conducted by the Universityof Ibadan from 2012/2013 to 2015/2016 with emphasis on gender and age-group performance inthe two examinations. The secondary data used for this research comprised of the records of all100 Level students admitted into the University from 2012/2013 to 2015/2016 academic sessionsthrough UTME and Post-UTME. The data collected were analysed using descriptive statistics, independent samples t test and Pearson Product Moment Correlation Coefficient r. The results [(2012/13: 49.3%; 50.7%); (2013/14: 53.5%;46.5%); (2014/15: 53%;47%) and (2015/16:53.3%;46.7%)], for male and female respectively showed that more male candidates were admitted compared to their female counterpart in each academic session except the 2012/2013 session that had higher female enrolment. More than 80% of the students were in the 16-20 age group. Theindependent t-test, for UTME and Post-UTME respectively, showed that the males had highermean scores than the females and these mean scores were significant in all the sessions except inthe 2015/16 session [(2012/13: P = .00; .04); (2013/14: P = .00; .03); (2014/15: P = .00; .00);(2015/16: P = .32; .29)]. The independent t-test for Post-UTME showed that the 16-20 age grouphad higher mean scores in the Post-UTME than the 21 & above age group in all the sessions butthe only significant Post-UTME mean score for this group was in the 2012/13 session (P = .00).Also, the independent t-test for UTME showed that the 21 & above age group had higher meanscores in the UTME than the 16-20 age group in all the sessions except the 2015/16 session butthe only significant UTME mean score for this group was in the 2013/14 session (P = .03). The Pearson Product Moment Correlation Coefficient r was 0.306, -0.351, 0.456 and 0.641 for 2012/2013, 2013/2014, 2014/2015 and 2015/2016 respectively. All the r values were positively significant at 5% level except the value of r which was negatively significant for 2013/2014 session. The progressive and significant positive increase in the value of r in all the sessions except the 2013/2014 academic session suggested tacit support for the scrapping of the Post-UTME in the Nigerian University system.

 C o m m e n t: The original description is based on two females from "Ilica im Tal von Ardeşen (Kaçkar-Daĝlari), 1600-2000 m " (KORGE 1971). SMETANA (1995) and SOLODOVNIKOV (2005) provided additional records from Rize and Artvin provinces, plus one vague record without specified locality ("Armen. Geb." = Armenisches Gebirge), which was – probably erroneously – interpreted as an Armenian locality by SOLODOVNIKOV (2005) and subsequently SCHÜLKE & SMETANA (2015). The currently known records suggest that the restricted distribution of Q. walteri somewhat overlaps with that of Q. smetanai (Map 2).
 KORGE (1971) tentatively placed Q. walteri in the subgenus Microsaurus, at the same time expressing his doubts regarding the subgeneric assignment. SMETANA (1995) subsequently moved the species to Raphirus, based on plausible morphological arguments. Strangely, he listed it in Microsaurus again in the first edition of the Palaearctic Catalogue (SMETANA 2004), most likely a lapsus. SOLODOVNIKOV (2005) adopted this concept solely on the grounds that this was "the latest published assignment". However, the distribution pattern and the presence of several other morphologically similar species in the Caucasus region suggest that Q. walteri belongs to the same group as Q. boluensis, Q. smetanai, Q. obliqueseriatus, and allied species (all of which are currently assigned to Raphirus); I have been unable to find any significant characters indicating otherwise. Consequently, Q. walteri is transferred to Raphirus again.
 The photo of the habitus provided by SOLODOVNIKOV (2005) suggests that the body of Q. walteri is of nearly uniformly blackish coloration, whereas in fact the head is darkbrown to blackish brown, the pronotum is dark-brown with reddish margins, the elytra are uniformly reddish, and the abdomen is reddish-brown to dark-brown with the posterior margins of the tergites reddish.

description: Barium (Ba) dwarfs and CH subgiants are the less-evolved analogues of Ba and CH giants. They are F- to G-type main-sequence stars polluted with heavy elements by a binary companion when the latter was on the Asymptotic Giant Branch (AGB). This companion is now a white dwarf that in most cases cannot be directly detected. We present a large systematic study of 60 objects classified as Ba dwarfs or CH subgiants. Combining radial-velocity measurements from HERMES and SALT high-resolution spectra with radial-velocity data from CORAVEL and CORALIE, we determine the orbital parameters of 27 systems. We also derive their masses by comparing their location in the Hertzsprung-Russell diagram with evolutionary models. We confirm that Ba dwarfs and CH subgiants are not at different evolutionary stages and have similar metallicities, despite their different names. Additionally, Ba giants appear significantly more massive than their main-sequence analogues. This is likely due to observational biases against the detection of hotter main-sequence post-mass-transfer objects. Combining our spectroscopic orbits with the Hipparcos astrometric data, we derive the orbital inclinations and the mass of the WD companion for four systems. Since this cannot be done for all systems in our sample yet (but should be with upcoming Gaia data releases), we also analyse the mass-function distribution of our binaries. We can model this distribution with very narrow mass distributions for the two components and random orbital orientation on the sky. Finally, based on BINSTAR evolutionary models, we suggest that the orbital evolution of low-mass Ba systems can be affected by a second phase of interaction along the Red Giant Branch of the Ba star, impacting on the eccentricities and periods of the giants.

description: Our study employs sentiment analysis to evaluate the compatibility of Amazon.com reviews with their corresponding ratings. Sentiment analysis is the task of identifying and classifying the sentiment expressed in a piece of text as being positive or negative. On e-commerce websites such as Amazon.com, consumers can submit their reviews along with a specific polarity rating. In some instances, there is a mismatch between the review and the rating. To identify the reviews with mismatched ratings we performed sentiment analysis using deep learning on Amazon.com product review data. Product reviews were converted to vectors using paragraph vector, which then was used to train a recurrent neural network with gated recurrent unit. Our model incorporated both semantic relationship of review text and product information. We also developed a web service application that predicts the rating score for a submitted review using the trained model and if there is a mismatch between predicted rating score and submitted rating score, it provides feedback to the reviewer.

We discuss cases where big set means: set of positive Lebesgue measure, set of full Lebesgue measure, Baire measurable set of second Baire category and comeagre set. In the first case (set of positive measure) we obtain the theorem due to Eggleston. In fact we give a simplified version of the proof given by J. Cichon. To prove these theorems we use Shoenfield's theorem about absoluteness for $Σ^1_2$-sentences.

description: We study the dependence of the local density of states (LDOS) on coordinates for a superconductor-ferromagnet (S/F) bilayer and a S/F/S structure assuming that the exchange energy h in the ferromagnet is sufficiently large: $% hτ>>1,$ where $τ$ is the elastic relaxation time. This limit cannot be described by the Usadel equation and we solve the more general Eilenberger equation. We demonstrate that, in the main approximation in the parameter $% (hτ)^{-1}$, the proximity effect does not lead to a modification of the LDOS in the S/F system and a non-trivial dependence on coordinates shows up in next orders in $(hτ) ^{-1}.$ In the S/F/S sandwich the correction to the LDOS is nonzero in the main approximation and depends on the phase difference between the superconductors. We also calculate the superconducting critical temperature $T_{c}$ for the bilayered system and show that it does not depend on the exchange energy of the ferromagnet in the limit of large h and a thick F layer.

description: Research software (RS) is designed to facilitate answering research questions, and it achieves this goal by running calculations, modeling some phenomena or managing and visualizing datasets, among many others. This is what RS is meant to accomplish, first and foremost, and everything that does not go in this direction is never a priority. GUIs in research software are nearly always considered as an aftermath - if considered at all! -, and add-on usually not very sophisticated to try to make the software more accessible. And the result is rarely fit for purpose. In this first lecture of the course we will try to answer the question of when research software might benefit from a GUI, when it will not, and what the benefits that having a well design GUI can bring to the table. This presentation is part of the workshop "Graphical User Interfaces for Research Software", delivered by Diego Alonso Álvarez and supported by the Software Sustainability Institute and Imperial College London.

description: Based on the theory of independently scattered random measures, we introduce a natural generalisation of Gaussian space-time white noise to a Levy-type setting, which we call Levy-valued random measures. We determine the subclass of cylindrical Levy processes which correspond to Levy-valued random measures, and describe the elements of this subclass uniquely by their characteristic function. We embed the Levy-valued random measure, or the corresponding cylindrical Levy process, in the space of general and tempered distributions. For the latter case, we show that this embedding is possible if and only if a certain integrability condition is satisfied. Similar to existing definitions, we introduce Levy-valued additive sheets, and show that integrating a Levy-valued random measure in space defines a Levy-valued additive sheet. This relation is manifested by the result, that a Levy-valued random measure can be viewed as the weak derivative of a Levy-valued additive sheet in the space of distributions.

description: Nigeria possesses enormous potentials in the agricultural sector especially in the cassava sub-sector. This paper reviews the cassava production, consumption and utilization along its value chain globally. The paper focuses on Nigeria’s cassava trade outlook and how it can compete favourably with other exporting nations while examining its prospects, strategies for development and challenges the cassava sub-sector is facing in recent time. Cassava production in Nigeria reached the highest level with an estimated value of 59million and accounted for 20.4% world share in 2017. Egypt is the only African country ranked among the top ten highest exporters of cassava in the world with export value of $20.7million and also the highest cassava exporter in Africa even though not among the highest producers of cassava in Africa and globally. Cassava is unarguably the most important root crop in Nigeria in terms of consumption. As the highest producer of cassava in the world, Nigeria recorded a small total export value ($1.25million) when compared to other leading producers like Thailand with highest export value of $1.19billion in 2017. Nigeria and the rest of African nations are yet to harness the great trade possibilities in the cassava sub-sector when compared to other regions (like Asia and North America) of the world.
Improving the communication for children with speech disorder using the smart toys

description: An attempt is made to develop a smart toy to help the children suffering with communication disorders. The children suffering with such disorders need additional attention and guidance to understand different types of social events and life activities. Various issues and features of the children with speech disorders are identified in this study and based on the inputs from the study, a working architecture is proposed with suitable policies. A prediction module with a checker component is designed in this work to produce alerts in at the time of abnormal behaviour of the child with communication disorder. The model is designed very sensitively to the behaviour of the child for a particular voice tone, based on which the smart toy will change to tones automatically. Such an arrangement proved to be helpful for the children to improve the communication with other due to the inclusion of continuous training for the smart toy from the prediction module.

description: Throughout this Abstract, $G$ is a topological Abelian group and $\hat{G}$ is the space of continuous homomorphisms from $G$ into $T$ in the compact-open topology. A dense subgroup $D$ of $G$ determines $G$ if the (necessarily continuous) surjective isomorphism $\hat{G} \twoheadrightarrow \hat{D}$ given by $h\mapsto h|D$ is a homeomorphism, and $G$ is determined if each dense subgroup of $G$ determines $G$. The principal result in this area, obtained independently by L. Aussenhofer and M. J. Chasco}, is the following: Every metrizable group is determined. The authors offer several related results, including these. (1) There are (many) nonmetrizable, noncompact, determined groups. (2) If the dense subgroup $D_i$ determines $G_i$ with $G_i$ compact, then $\oplus_i D_i$ determines $Π_i G_i$. In particular, if each $G_i$ is compact then $\oplus_i G_i$ determines $Π_i G_i$. (3) Let $G$ be a locally bounded group and let $G^+$ denote $G$ with its Bohr topology. Then $G$ is determined if and only if ${G^+}$ is determined. (4) Let $non(N)$ be the least cardinal $κ$ such that some $X \subseteq T}$ of cardinality $κ$ has positive outer measure. No compact $G$ with $w(G)\geq non(N)$ is determined; thus if $non(N)=\aleph_1$ (in particular if CH holds), an infinite compact group $G$ is determined if and only if w(G)=ω$. Question. Is there in ZFC a cardinal $κ$ such that a compact group $G$ is determined if and only if $w(G)

description: We report the design and development of a compact electron and positron spectrometer based on tapered Neodymium Iron Boron magnets. We show that the tapered design forms a gradient magnetic field component allowing energy dependent focusing of the dispersed charged particles along a chosen detector plane using RADIA, a code developed by European Synchrotron Radiation Facility for solving three-dimensional magnetostatics configuration, and a fourth order Runge-Kutta Particle Tracking code. The mirror symmetric design allows for simultaneous detection of pairs i.e. electrons and positrons with energies from 2 MeV to 500 MeV. We have developed a prototype matching the design specifications. We investigate the effects of beam divergence on the energy resolution and signal conversion efficiency for a photo-stimulated luminescencebased Imaging Plates (IPs). The optimal entrance aperture of the magnet is found to be elliptical and bigger than that of conventional pinhole aperture-based spectrometer designs even for a divergent beam originating from a point source at 20 cm away (i.e. solid angle of ~8 milli steradians). The signal efficiency in BAS-IP of SR type ranges from 1% to 5% for a parallel beam incident on a circular aperture of 20 mm diameter type at a chosen detection plane whereas it drops by up to a factor of 3 in the presence of divergence of ~ 8 milli steradians. The proposed gradient magnet is suitable for the detection of low flux and/or monoenergetic type electron/positron signals with finite transverse sizes. It offers unparalleled advantages for gammaray spectroscopy in the intermediate MeV range.

description: We study a Gaussian Potts-Hopfield model. Whereas for Ising spins and two disorder variables per site the chaotic pair scenario is realized, we find that for q-state Potts spins [{q(q-1} \over 2]-tuples occur. Beyond the breaking of a continous stochastic symmetry, we study the fluctuations and obtain the Newman-Stein metastate description for our model.

description: The period 1989-2000 provided a huge yield of precise electroweak data from the LEP and SLC experiments. Many analyses of these data are now complete, but others, particularly of the full LEP-2 data samples, continue. The main electroweak physics results from these data are summarised, and stringent tests of the Standard Model are made with the combined samples. The direct search for the missing link of the Standard Model, the Higgs boson, is also briefly reviewed.

 C o m m e n t: Quedius obliqueseriatus was originally attributed to the subgenus Sauridus MULSANT & REY, 1876, today a junior synonym of Raphirus STEPHENS, 1829 (EPPELSHEIM 1889). The species was revised by SOLODOVNIKOV (2004), who did not explicitly assign it to a subgenus. However, according SOLODOVNIKOV (2004, 2005), it is closely allied to Q. boluensis and some species described in the second paper (Q. nonseriatus, Q. henrii, Q, humosus), which he attributed to Raphirus. Nevertheless, Q. obliqueseriatus is listed in the subgenus Microsaurus in SCHÜLKE & SMETANA (2015). Since Q. obliqueseriatus is clearly closely related to the other species treated in the previous sections, it should be placed in Raphirus. The species is endemic to the Krasnodar region in the Northwest Caucasus (SOLODOVNIKOV 2004).

description: This paper presents a study on natural language to sign language translation with human-robot interaction application purposes. By means of the presented methodology, the humanoid robot TEO is expected to represent Spanish sign language automatically by converting text into movements, thanks to the performance of neural networks. Natural language to sign language translation presents several challenges to developers, such as the discordance between the length of input and output data and the use of non-manual markers. Therefore, neural networks and, consequently, sequence-to-sequence models, are selected as a data-driven system to avoid traditional expert system approaches or temporal dependencies limitations that lead to limited or too complex translation systems. To achieve these objectives, it is necessary to find a way to perform human skeleton acquisition in order to collect the signing input data. OpenPose and skeletonRetriever are proposed for this purpose and a 3D sensor specification study is developed to select the best acquisition hardware.

Sedimentation of a suspension of paramagnetic particles in an external magnetic field

description: We investigate the sedimentation of initially packed paramagnetic particles in presence of a homogeneous external magnetic field, in a Hele-Shaw cell filled with water. Although the magnetic susceptibility of the particles is small and the particle-particle induced magnetic interactions are significantly smaller compared to the gravitational acceleration, we do observe a measurable reduction of the decompaction rate as the amplitude of the applied magnetic field is increased. While induced magnetic dipole-dipole interactions between particles can be either attracting or repulsive depending on the particles relative alignment, our observations reveal an effective overall enhancement of the cohesion of the initial pack of particles due to the induced interactions, very likely promoting internal chain forces in the initial pack of particles. The influence of the magnetic field on the particles once they disperse after being decompacted is on the other hand found to remain marginal.

 C o m m e n t: SCHÜLKE & SMETANA (2015) list this species for Greece, Lebanon, Israel, and Iran. Recently it was reported from the Greek island Samos, close to the Turkish coast (ASSING 2015). Quedius nivicola was previously unknown from Turkey, from where it is here reported for the first time.
 The above specimens from Greece were collected in greater numbers (14 and three specimens, respectively) in two localities with subterranean pitfall traps. The material from Turkey, by contrast, is mostly represented by singletons, on rarer occasions also by two or (in one case) three specimens per locality and was found exclusively by sifting. These observations suggest that Q. nivicola is not a typical inhabitant of the leaf litter like most of its congeners, but lives in a subterranean habitat of unknown identity.
