description: It is shown that Julia-Zee dyons do not admit slowly rotating excitations. This is achieved by investigating the complete set of stationary excitations which can give rise to non-vanishing angular momentum. The relevant zero modes are parametrized in a gauge invariant way and analyzed by means of a harmonic decomposition. Since general arguments show that the solutions to the linearized Bogomol'nyi equations cannot contribute to the angular momentum, the relevant modes are governed by a set of electric and a set of non self-dual magnetic perturbation equations. The absence of axial dipole deformations is also established.

description: Our study concerns students' initiative in mathematics, in the context of the Central African Republic. We focus on double statistical series and linear regression. We refer to the Anthropological Theory of Didactics. We proposed a problem on the theme of linear trend estimation to students in grade 12. In this article, we present and analyse this problem and we also analyse the students' productions, in terms of taking initiatives. The modelling activity offers possibilities, but the students' initiative is reduced, and the difficulties of calculation are an obstacle.

A System of Interaction and Structure III: The Complexity of BV and Pomset Logic

Subjects: subject: Logic in Computer Science (cs.LO)
subject: FOS: Computer and information sciences

description: Pomset logic and BV are both logics that extend multiplicative linear logic (with Mix) with a third connective that is self-dual and non-commutative. Whereas pomset logic originates from the study of coherence spaces and proof nets, BV originates from the study of series-parallel orders, cographs, and proof systems. Both logics enjoy a cut-admissibility result, but for neither logic can this be done in the sequent calculus. Provability in pomset logic can be checked via a proof net correctness criterion and in BV via a deep inference proof system. It has long been conjectured that these two logics are the same.
 In this paper we show that this conjecture is false. We also investigate the complexity of the two logics, exhibiting a huge gap between the two. Whereas provability in BV is NP-complete, provability in pomset logic is $Σ_2^p$-complete. We also make some observations with respect to possible sequent systems for the two logics.

description: Using a multi-orbital tight-binding model, we have studied the edge states of zigzag silicene, germanene, and stanene nanoribbons (ZSiNRs, ZGeNRs and ZSnNRs, respectively) in the presence of the Coulomb interaction and a vertical electric field. The resulting edge states have non-linear energy dispersions due to multi-orbital effects, and the nanoribbons show induced magnetization at the edges. Owing to this non-linear dispersion, ZSiNRs, ZGeNRs and ZSnNRs may not provide superior performance in field effect transistors, as has been proposed from single-orbital tight-binding model calculations. We propose an effective low-energy model that describes the edge states of ZSiNRs, ZGeNRs, and ZSnNRs. We demonstrate that the edge states of ZGeNR and ZSnNR show anti-crossing of bands with opposite spins, even if only out-of-plane edge magnetization is present. The ability to tune the spin polarizations of the edge states by applying an electric field points to future opportunities to fabricate silicene, germanene and stanene nanoribbons as spintronics devices.

description: This paper uses data from the New Zealand Census to examine how the supply of recent migrants in particular skill groups affects the geographic mobility of the New Zealand-born and earlier migrants. We identify the impact of recent migration on mobility using the ‘areaanalysis’ approach, which exploits the fact that immigration is spatially concentrated, and thus a change in the local supply of migrants in a particular skill group should have an impact on the mobility of similarly skilled non-migrants in that local labour market. Overall, our results provide little support for the hypothesis that migrant inflows displace either the NZ-born or earlier migrants with similar skills in the areas that new migrants are settling. If anything, they suggest that there are positive spillovers between recent migrants and other individuals that encourage individuals to move to or remain in the areas in which similarly skilled migrants are settling. Thus, it appears unlikely that internal mobility moderates any potential impacts of immigration on labour or housing markets in New Zealand.
Sine-Gordon mean field theory of a Coulomb Gas

description: Sine-Gordon field theory is used to investigate the phase diagram of a neutral Coulomb gas. A variational mean field free energy is constructed and the corresponding phase diagrams in two (2d) and three dimensions (3d) are obtained. When analyzed in terms of chemical potential, the Sine-Gordon theory predicts the phase diagram topologically identical with the Monte Carlo simulations and a recently developed Debye-Hückel-Bjerrum (DHBj) theory. In 2d we find that the infinite order Kosterlitz-Thouless line terminates in a tricritical point, after which the metal-insulator transition becomes first order. However, when the transformation from chemical potential to the density is made the whole of the insulating phase is mapped onto zero density.

description: Background Seasonal influenza contributes substantially to the burden of communicable diseases in Europe, especially among paediatric populations and the elderly. The aim of the present study was to estimate the incidence of seasonal influenza in Germany, the probabilities of related complications and the economic burden of influenza per case and on a population level for different age groups. Methods Claims data from 2012 to 2014 from > 8 million insured of a large German sick-ness fund were analysed. A matched case control study was used on a sub-sample of 100,000 influenza cases to calculate complication rates for ear infections/acute otitis media (AOM) and community-acquired pneumonia (CAP) as well as resource use and costs for seven age groups. Results Incidence of seasonal influenza varies between the years and is highest among infants and children 2 to 5 years of age. AOM is more likely in the younger age groups with up to 14% more patients in the influenza group than in the control group. CAP is more frequently observed in the younger age groups and in influenza patients 60 years and older. The manifestation of one influenza complication (AOM or CAP) significantly in-creases the occurrence of a second complication (AOM or CAP). The economic burden per case is highest in infants (€251.91) and persons over 60 years of age (€131.59). Conclusion The burden of influenza is highest among infants and young children, which is also reflected in the economic burden. Influenza related costs per case are nearly double for infants compared to persons over 60 years of age.

description: The purpose of this research is to investigate the traces of empiricist influences in kindergarten teachers' representations of the practices they tend to follow when developing natural science activities in kindergarten. A quantitative approach was used, with the research tool being an electronic questionnaire that was completed online by 94 kindergarten teachers working in publics preschools. The questionnaire was first used in a pilot survey and, after receiving feedback, was expanded for the main research. Analysis of the results showed that kindergarten teachers' representations of their teaching choices and their students' actions are characterized by practices that are influenced by the empiricist teaching strategy.

description: This study, which is part of a larger ongoing work, utilizing the concepts of "scientific field", “scientific capital” and “symbolic power” from Pierre Bourdieu's theory, as a framework of theoretical presuppositions and heuristics of understanding in the analysis of the data, aims to investigate the perceptions of a Professor (informant) in a Greek university regarding the influence of the university field and the constraints it imposes on the “practice of the academic profession” through the dialectical relationship between teaching and research work. The research was conducted using the biographical narrative interview. The results of the study showed that the university field has a significant impact on the academic profession. It was further shown that administrative positions, progression through the ranks and the immense, profound importance of the research rather than teaching dimension of the academic’ roles are crucial parameters in the practice of the academic profession.

description: In China, numerous policy interventions have been undertaken to promote exports of the manufacturing industry. In this paper, we study how the burgeoning export sector has affected the performance of the manufacturing industry. In particular, we focus our attention on two dimensions: efficiency and technological advancement, and the presence of spillovers and path dependences. The main feature of our empirical study is to distinguish between different types of firms according to their output orientation, ownership, and technology intensity. We also recognize that outputs for domestic use and exports may be produced using different technologies. Our results demonstrate the superiority of multi-output firms in both efficiency and technological advancement. Further, these firms generate strong outgoing spillovers to the industry. In contrast, export-only firms are found to be the most inefficient and technologically underdeveloped, while barely generating outgoing spillovers. In terms of efficiency and technological advancement, we also find that foreign- and privately-owned firms and high-tech firms are the best performers. Finally, we find evidence of strong path dependence and weak absorptive capacities for incoming spillovers in the manufacturing industry. We give targeted policy recommendations based on these findings.

Our attack uses the fact that the roots of $Φ_{p^k}(x)$ over suitable extensions of $\mathbb{F}_q$ have zero-trace and has overwhelming success probability as a function of the number of input samples. An implementation in Maple and some examples of our attack are also provided.

description: Purpose: There are no examples in the literature of successful long-term hospital-wide implementation of nurse-led dysphagia screening. This article aims to describe strategies used to implement hospital-wide dysphagia screening in a large acute tertiary teaching hospital in Australia. It reports on compliance, accuracy and nursing staff satisfaction using the validated Royal Brisbane and Women’s Hospital Dysphagia Screening Tool (RBWH DST). Method: A retrospective observational study of audit data was conducted to examine hospital-wide compliance and accuracy of dysphagia screen completion. A nursing staff survey measured staff satisfaction. Implementation included: (1) utilisation of validated tool (RBWH DST); (2) key stakeholder engagement and strong governance; (3) policy development; (4) education; and (5) review and monitoring processes. Result: Audits conducted over a 9-year period (n = 3726) showed an average hospital-wide compliance rate of 74% and an accuracy rate of 82%. A nurse satisfaction survey (n = 109) showed high levels of satisfaction associated with using the RBWH DST. Conclusion: The RBWH DST was implemented in a large acute tertiary teaching hospital with acceptable compliance and accuracy rates and favourable nursing staff satisfaction. Further study is required to objectively evaluate patient health and cost benefits associated with using the RBWH DST.

description: The (bitwise) complement $\overline{x}$ of a binary word $x$ is obtained by changing each $0$ in $x$ to $1$ and vice versa. An $\textit{antisquare}$ is a nonempty word of the form $x\, \overline{x}$. In this paper, we study infinite binary words that do not contain arbitrarily large antisquares. For example, we show that the repetition threshold for the language of infinite binary words containing exactly two distinct antisquares is $(5+\sqrt{5})/2$. We also study repetition thresholds for related classes, where "two" in the previous sentence is replaced by a larger number.
 We say a binary word is $\textit{good}$ if the only antisquares it contains are $01$ and $10$. We characterize the minimal antisquares, that is, those words that are antisquares but all proper factors are good. We determine the growth rate of the number of good words of length $n$ and determine the repetition threshold between polynomial and exponential growth for the number of good words.

description: We consider relational semantics (R-models) for the Lambek calculus extended with intersection and explicit constants for zero and unit. For its variant without constants and a restriction which disallows empty antecedents, Andreka and Mikulas (1994) prove strong completeness. We show that it fails without this restriction, but, on the other hand, prove weak completeness for non-standard interpretation of constants. For the standard interpretation, even weak completeness fails. The weak completeness result extends to an infinitary setting, for so-called iterative divisions (Kleene star under division). We also prove strong completeness results for product-free fragments.

description: Job-related anxiety, in contrast to general trait-anxiety, is by its very nature associated with problems of participation at work. The aim of this study is to investigate the relation between general trait-anxiety and specific job-related anxiety and to examine whether job-anxiety and trait-anxiety are differently associated with sick leave. 190 inpatients of a psychosomatic and orthopedic rehabilitation center with mental and somatic disorders filled in the Job-Anxiety-Scale (JAS) and the State-Trait-Anxiety-Inventory (STAI-T). Additionally, information on age, gender, the current duration of sick leave in weeks, employment status, duration of unemployment, and position at the workplace were collected.
Highest scores of job-anxiety were found for the JAS-dimensions “job-related worries” and “health anxieties”, followed by “cognitions of insufficiency,” “stimulus-related anxieties,” and “social anxieties.” JAS and STAI-T were significantly correlated. Job-anxiety, in contrast to trait-anxiety, was significantly related to duration of sick leave. Women showed higher scores on the STAI-T but not on the JAS.
It can be concluded that job-anxiety is related to but not identical with trait-anxiety. Job-anxiety is important to understand sick leave and appears as a multidimensional and clinically important phenomenon.

The study was carried out in Cameroon in a scientific 12th grade class. The class divided into two groups: “experimental” group having followed the practical training and "theoretical" group not having followed the practical training. An analysis was carried out in order to show that the students having followed the practical training circulate more between the levels of knowledge compared to those of the theoretical class.

Black hole hyperaccretion inflow-outflow model. II. Long-duration gamma-ray bursts and supernova $\rm ^{56}Ni$ bumps

description: Long-duration gamma-ray bursts (LGRBs) associated with supernovae (SNe) are possibly born out of the death of a massive star. After the star collapses, a stellar-mass black hole (BH) is formed, surrounded by a hyperaccretion disk with outflows. Blandford-Znajek jets can be launched and then break out from the envelope to power LGRBs. The jet luminosity depends on the net inflow accretion rate at the inner radius of the disk. Furthermore, $\rm ^{56}Ni$ synthesis should occur in the strong outflows from the accretion disk. The decay of $\rm ^{56}Ni$ is considered to be the possible origin of SN bumps in the subsequent optical afterglows of LGRBs. If $\rm ^{56}Ni$ originates entirely from the outflows, there is competition between the luminosities of LGRBs and those of the corresponding $\rm ^{56}Ni$ bumps because of the material distribution between the disk inflows and outflows. In this paper, we investigated these two luminosities based on 15 cases of LGRB-SN in the framework of the BH hyperaccretion inflow-outflow model. Then, one can constrain the characteristics of the progenitor stars of these LGRBs. The results indicate that these LGRBs may originate from the low-metallicity ($Z\lesssim 10^{-2}Z_{\odot}$, where $Z$ and $Z_{\odot}$ are the metallicities of the stars and the Sun, respectively) stars or some massive solar-metallicity stars. For ultra-LGRBs (ULGRBs), such as GRB 111209A, most of the massive low-metallicity stars with $Z \lesssim 10^{-2}Z_{\odot}$ could be progenitors only if very strong outflows are launched from the disks. When the contributions of nucleosynthesis in the disk outflows are considered, there is no shortage of $\rm ^{56}Ni$ mass for luminous SNe associated with ULGRBs.

subject: 150

description: Objective: Job-related distress has often been found to be related with low social support at work. The question is whether dimensions of social support outside work have a similar relation with job-anxiety or whether they are independent.
Method: A sample of 154 employed inpatients from a psychosomatic rehabilitation center (70% women) completed self-rating questionnaires on perceived symptom load in the domain of work (job-anxiety) and in general life (general psychosomatic symptom load), and on perceived social support at work and outside work.
Results: Job-anxiety showed moderate correlations with the perceived level of social support through colleagues. Thereby the social support dimensions of “consolation and encouragement” and “criticism, overload, rejection” were more strongly related to job-anxiety than the dimension of “practical support”. There were no significant correlations between job-anxiety and social support through household members, leisure time partners or neighbors.
Conclusion: Social support is in a specific way important in the context of work other than concerning general mental health outside the work-context. Job-anxiety is a domain-specific clinical phenomenon and independent from perceived social support outside the workplace.

description: We present the Data Release 4&5 quasar catalog from the quasar survey by Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), which includes quasars observed between September 2015 and June 2017. There are a total of 19,253 quasars identified by visual inspections of the spectra. Among them, 11,458 are independently discovered by LAMOST, in which 3296 were reported by SDSS DR12 and DR14 quasar catalog after our survey began, while the rest 8162 are new discoveries of LAMOST. We provide the emission line measurements for the Halpha, Hbeta, MgII and/or CIV for 18100 quasars. Since LAMOST does not have absolute flux calibration information, we obtain the monochromatic continuum luminosities by fitting the SDSS photometric data using the quasar spectra, and then estimate the black hole masses. The catalog and spectra for these quasars are available online. This is the third installment in the series of LAMOST quasar survey which has released spectra for totally ~43,000 quasars hitherto. There are 24,772 independently discovered quasars, 17,128 of which are newly discovered. In addition to the great supplement to the new quasar discoveries, LAMOST has also provided a large database (overlapped with SDSS) for investigating the quasar spectral variability and discovering unusual quasars, including changing-look quasars, with ongoing and upcoming large surveys.

description: We investigate the possibility of measuring the Hubble constant, the fractional energy density components and the equation of state parameter of the ``dark energy'' using lensed multiple images of high-redshift supernovae. With future instruments, such as the SNAP and NGST satellites, it will become possible to observe several hundred lensed core-collapse supernovae with multiple images. Accurate measurements of the image separation, flux-ratio, time-delay and lensing foreground galaxy will provide complementary information to the cosmological tests based on, e.g., the magnitude-redshift relation of Type Ia supernovae, especially with regards to the Hubble parameter that could be measured with a statistical uncertainty at the one percent level. Assuming a flat universe, the statistical uncertainty on the mass density is found to be sigma^stat_m <0.05. However, systematic effects from the uncertainty of the lens modeling are likely to dominate. E.g., if the lensing galaxies are extremely compact but are (erroneously) modeled as singular isothermal spheres, the mass density is biased by sigma^syst_m =0.1. We argue that wide-field near-IR instruments such as the one proposed for the SNAP mission are critical for collecting large statistics of lensed supernovae.

description: In this paper we propose a new approach to realizability interpretations for nonstandard arithmetic. We deal with nonstandard analysis in the context of (semi)intuitionistic realizability, focusing on the Lightstone-Robinson construction of a model for nonstandard analysis through an ultrapower. In particular, we consider an extension of the $λ$-calculus with a memory cell, that contains an integer (the state), in order to indicate in which slice of the ultrapower $\cal{M}^{\mathbb{N}}$ the computation is being done. We pay attention to the nonstandard principles (and their computational content) obtainable in this setting. In particular, we give non-trivial realizers to Idealization and a non-standard version of the LLPO principle. We then discuss how to quotient this product to mimic the Lightstone-Robinson construction.

A \emph{strongly edge-colored} graph is a proper edge-colored graph such that every path of length $3$ is rainbow. We call an edge-colored graph $G^c$ \emph{rainbow vertex pair-pancyclic} if any two vertices in $G^c$ are contained in a rainbow cycle of length $\ell$ for each $\ell$ with $3 \leq \ell \leq n$. In this paper, we show that every strongly edge-colored graph $G^c$ of order $n$ with minimum degree $δ\geq \frac{2n}{3}+1$ is rainbow vertex pair-pancyclicity.

description: We introduce the stack of r-spin maps. These are stable maps into a variety V from n-pointed algebraic curves of genus g, with the additional data of an r-spin structure on the curve. We prove that this stack is a Deligne-Mumford stack, and we define analogs of the Gromov-Witten classes associated to these spaces. We show that these classes yield a cohomological field theory (CohFT) that is the tensor product of the CohFT associated to the usual Gromov-Witten invariants of V and the r-spin CohFT. When r=2, our construction gives the usual Gromov-Witten invariants of V. Restricting to genus zero, we obtain the notion of an r-spin quantum cohomology of V, whose Frobenius structure is isomorphic to the tensor product of the Frobenius manifolds corresponding to the quantum cohomology of V and the r-th Gelfand-Dickey hierarchy (or, equivalently, the A_{r-1} singularity). We also prove a generalization of the descent property which, in particular, explains the appearance of the psi-classes in the definition of gravitational descendants. Finally, we compute the small phase space potential function when r=3 and V=CP^1.

description: We introduce a meta-model based on formal languages, dubbed formal choreographic languages, to study message-passing systems. Our framework allows us to generalise standard constructions from the literature and to compare them. In particular, we consider notions such as global view, local view, and projections from the former to the latter. The correctness of local views projected from global views is characterised in terms of a closure property. We consider a number of communication properties -- such as (dead)lock-freedom -- and give conditions on formal choreographic languages to guarantee them. Finally, we show how formal choreographic languages can capture existing formalisms; specifically we consider communicating finite-state machines, choreography automata, and multiparty session types. Notably, formal choreographic languages, differently from most approaches in the literature, can naturally model systems exhibiting non-regular behaviour.

description: The relational calculus (RC) is a concise, declarative query language. However, existing RC query evaluation approaches are inefficient and often deviate from established algorithms based on finite tables used in database management systems. We devise a new translation of an arbitrary RC query into two safe-range queries, for which the finiteness of the query's evaluation result is guaranteed. Assuming an infinite domain, the two queries have the following meaning: The first is closed and characterizes the original query's relative safety, i.e., whether given a fixed database, the original query evaluates to a finite relation. The second safe-range query is equivalent to the original query, if the latter is relatively safe. We compose our translation with other, more standard ones to ultimately obtain two SQL queries. This allows us to use standard database management systems to evaluate arbitrary RC queries. We show that our translation improves the time complexity over existing approaches, which we also empirically confirm in both realistic and synthetic experiments.
Gamma-Ray Bursts and Quantum Cosmic Censorship

description: Gamma-ray bursts are believed to result from the coalescence of binary neutron stars. However, the standard proposals for conversion of the gravitational energy to thermal energy have difficulties. We show that if the merger of the two neutron stars results in a naked singularity, instead of a black hole, the ensuing quantum particle creation can provide the requisite thermal energy in a straightforward way. The back-reaction of the created particles can avoid the formation of the naked singularity predicted by the classical theory. Hence cosmic censorship holds in the quantum theory, even if it were to be violated in classical general relativity.

description: For those not of a technical bent, there is a great deal of confusion surrounding the terms 'interoperability' and 'integration', especially when it comes to the exchange of information in 'black-box' systems. The average depositor of data doesn't want (or need) to know how data and meta data move around a system as long as what they put in eventually gets to where it should be, in the form it should be and can be seen by the appropriate people. However, a basic understanding of the similarities and differences between 'interoperable' systems and 'integrated' systems and the pros and cons of each approach when it comes to depositing, preserving and discovering data will help users and administrators make informed decisions when it comes to the specification of data management systems, and will help inform their day-to-day data management practices. This poster is intended to highlight those similarities and differences, pros and cons.

description: Hintergrund und Fragestellung: Herzinsuffizienz ist ein häufiges klinisches Syndrom mit wachsender Bedeutung und schlechter Prognose. Patientenschulung ist ein zentraler Bestandteil der medizinischen Rehabilitation mit dem Ziel die Folgen chronischer Krankheiten durch gezielte Förderung von Krankheitskompetenz und Selbstmanagement zu verringern und die Lebensqualität von Patienten zu verbessern.
Im Rahmen der vorliegenden explorativen Untersuchung wird ein neu entwickeltes Patientenschulungsprogramm für Herzinsuffizienz vorgestellt und die direkte Bewertung des Programms durch Patienten, die Veränderungen des krankheitsbezogenen Wissens, die gesundheits- und krankheitsbezogene Lebensqualität, sowie die psychische Symptombelastung im Verlauf erfasst.
Methode: 64 Patienten (79,7% Männer) nahmen im Rahmen einer kardiologischen Rehabilitation an einer kompetenz-fokussierenden Schulung für Herzinsuffizienzpatienten teil. Die Patienten füllten zu Beginn, am Ende sowie sechs Monate nach der Rehabilitation Selbstbeurteilungsfragebögen zum psychischen Wohlbefinden und zur Lebenszufriedenheit, einen auf die Schulungsinhalte bezogenen Wissenstest und einen Evaluationsfragebogen aus.
Ergebnisse: Die Bewertung des Schulungsprogramms durch die Teilnehmer war sehr gut. Wissen und Lebensqualität waren am Ende und sechs Monate nach der Rehabilitation signifikant gestiegen, die psychische Symptombelastung (Ängstlichkeit und Depressivität) reduziert.
Schlussfolgerung: Während einer kardiologischen Rehabilitation erfährt ein strukturiertes Schulungsprogramm für Patienten mit Herzinsuffizienz eine hohe Akzeptanz seitens der Patienten. Die Patienten erfahren eine Verbesserung ihres Wissens über die Erkrankung, eine Reduktion von Angst- und Depressivitätserleben und eine Verbesserung ihrer Lebensqualität. Die Indikation für eine Schulung muss insbesondere bei Patienten mit Angstneigung sorgfältig abgeklärt werden.

description: It’s widely accepted that good quality metadata is a significant factor in discovery and reuse of digital objects. Because of the way data standards and infrastructure has evolved, much of the metadata currently in circulation is either in English and/or based upon standards formulated in English. This reduces discovery, impact (and potentially reuse) in areas of the world where English is not widely spoken. The converse is also true when it comes to the impact of non-English digital objects and metadata on the English-speaking world. There are many auto-translation tools available that lend themselves fairly well to the translation of words and short passages of text… such as keywords/phrases and abstracts. This presentation explores the potential (and difficulties associated with) the incorporation of such tools in deposit and preservation workflows.

description: Modern day school administration is facilitated by Information and Communication Technology (ICT) facilities. As technology improves, educational capability increases correspondingly. However, it is observed that most tertiary institutions in Osun State still face the challenges of poor teaching of large classes, delayed students results, poor records of staff and students’ information, poor payment mode of fees and other levies despite the general belief that educational inputs such as ICT facilities have been incorporated into the teaching, learning and general school administration of these institutions. Hence, this study tends to examine the availability and utilisation of ICTs in three tertiary institutions in Osun State. The population for the study consisted of the undergraduate students, academic staff and non-teaching staff. Specifically, convenience sampling technique was used to select 1479 respondents to include 1200 students and 279 teaching and non-teaching staff. One self-designed instrument was used for the study, titled “Availability and Utilization of Information and Communication Technology Facilities -Questionnaire (AUICTF-Q)”. The instrument was divided in to two parts; the first part was designed to elicit information from staff and students together while the other part was developed to elicit information from the staff and students separately in the three selected tertiary institutions in Osun State. The results showed that there is availability of ICT facilities in the administration of tertiary institutions in Osun State and that both the academic and administrative staffs make use of ICT facilities for administrative activities.

description: Despite the great promise of quantum machine learning models, there are several challenges one must overcome before unlocking their full potential. For instance, models based on quantum neural networks (QNNs) can suffer from excessive local minima and barren plateaus in their training landscapes. Recently, the nascent field of geometric quantum machine learning (GQML) has emerged as a potential solution to some of those issues. The key insight of GQML is that one should design architectures, such as equivariant QNNs, encoding the symmetries of the problem at hand. Here, we focus on problems with permutation symmetry (i.e., the group of symmetry $S_n$), and show how to build $S_n$-equivariant QNNs. We provide an analytical study of their performance, proving that they do not suffer from barren plateaus, quickly reach overparametrization, and generalize well from small amounts of data. To verify our results, we perform numerical simulations for a graph state classification task. Our work provides the first theoretical guarantees for equivariant QNNs, thus indicating the extreme power and potential of GQML.
