description: Τα πληροφοριακά συστήματα στη σύγχρονη εποχή, αποτελούν χρήσιμα εργαλεία για τους manager καθώς και για το σύνολο του υφιστάμενου προσωπικού. H μετάβαση στην ψηφιακή εποχή καθώς και η πάταξη της γραφειοκρατίας αποτελεί κοινή γραμμή πλεύσης μεταξύ των εμπλεκομένων ενός οργανισμού με κύριο στόχο, όχι τη δημιουργία ενός καθεστώτος ανομίας, αλλά τη μείωση του χρόνου διεκπεραίωσης υποθέσεων προς όφελος παραγωγικών δραστηριοτήτων και ταυτόχρονα της αύξησης του επιπέδου ασφαλείας και διαφάνειας. Ο Στρατός Ξηράς, που αναμφίβολα αποτελεί μία οργανωμένη δομή, δεν θα μπορούσε να αποτελεί εξαίρεση στην εξέλιξη της τεχνολογίας. Για τη διευκόλυνση πολλών σύγχρονων απαιτήσεων, ανέπτυξε την τελευταία 10ετία πληθώρα πληροφοριακών συστημάτων, τα περισσότερα εσωτερικής λειτουργίας για την εξυπηρέτηση διαφόρων διαδικασιών, με σκοπό την απλούστευση τους. Ένα από αυτά ήταν και το επίσημο site ενημέρωσης army.gr, το οποίο μετατράπηκε από μία απλή ενημερωτική σελίδα σε εργαλείο περάτωσης περιοδικών υποχρεώσεων των μόνιμων στελεχών. Η ανάγκη της εξέλιξης του παραπάνω πληροφοριακού συστήματος και της διασύνδεσης και αλληλεπίδρασης με άλλα, κρίνεται πλέον αναγκαία στα πλαίσια της διακλαδικότητας και της διαλειτουργικότητας, που αποτελούν οράματα της ηγεσίας των Ενόπλων Δυνάμεων και του Υπουργείου ψηφιακής διακυβέρνησης αντίστοιχα. Στόχος της παρούσας εργασίας είναι η αποτύπωση των αναγκών για αναβάθμιση της διαδικτυακής πλατφόρμας army.gr σύμφωνα με τα γραφειοκρατικά προβλήματα που αντιμετωπίζουν οι Μονάδες – Ανεξάρτητες Υπομονάδες του Στρατού Ξηράς, με κύριο γνώμονα την πλήρη καταπολέμηση τους και την εξοικονόμηση χρόνου εργασίας και πόρων που απαιτούνται για απλά ζητήματα της καθημερινότητας. Τα οφέλη της αναβάθμισης αυτής βρίσκουν άμεση εφαρμογή στους εκάστοτε επιτελείς, οι οποίοι δεν θα αποτελούν απλούς διεκπεραιωτές και διακινητές εγγράφων, αλλά θα εκμεταλλεύονται τις ώρες εργασίας και τους διατιθέμενους πόρους για την πραγματική σημασία της λέξης «επιτελής» δηλαδή ως «σύμβουλοι» του εκάστοτε Διοικητή.

description: Lateral ankle sprains often lead to long-term impairments including altered gait biomechanics. The current interventions used to treat LAS are ineffective at modifying gait or preventing long-term deficits including PTOA.Does vibration feedback gait retraining result in a LR change, and is it retained? Do changes in kinetic variables associate with outcomes within CAI domains (perceptual, sensorimotor, mechanical)?We conducted a repeated measures design with 19 individuals with CAI. Participants completed laboratory and RW sessions. We assessed baseline, post-test, and retention gait kinetics.We found decreases in vGRF LR after laboratory gait retraining baseline-posttest (p=0.026) and posttest-retention (p=0.016), but they weren’t retained, and no RW differences existed. Positive correlations occurred between LR change and IdFAI (p=0.019), LR and plantar cutaneous threshold at 1MTP (p=0.013), and phase 1 COP change with eyes open balance (p=0.035). An association existed between phase 1 COP change with a cavus foot compared to neutral (p=0.040).

description: We review the nascent but fast-growing literature on central bank digital currencies (CBDCs),
focusing on their potential impacts on private banks. We evaluate these impacts in three areas
of traditional banking: payments, lending, and liquidity and maturity transformation. For each
area, we discuss the lessons learned and identify gaps in the research yet to be fully explored.
We also take a broader look at CBDCs and highlight two promising directions for future
research. One is to study CBDCs through the lens of industrial organization, exploring issues
such as platform competition and business models. The second is the crypto space and its new
developments such as stablecoins and decentralized finance.

Dental Hygiene Education About Patients With Intellectual and Developmental Disabilities: A Survey of U.S. Dental Hygiene Programs
Creators: name: Cheung, Hannah
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: In 2019, the Commission on Dental Accreditation (CODA) changed its standard from “assessing treatment needs” to require “providing dental hygiene care” for dental hygiene students to obtain competency in the treatment of patients with special needs. The study’s purpose was to evaluate accredited U.S. dental hygiene programs’ preparation of their students treating patients with intellectual and developmental disabilities (IDD). A 25-item Qualtrics® survey was sent to 325 dental hygiene directors. Survey topics included curriculum content and structure, curriculum changes in response to new CODA standards, didactic and clinical experiences in treatment of patients with IDD. Descriptive statistics were calculated and comparisons were made using chi-square tests. The response rate was 29.5% (n=89/301 delivered surveys). Results indicated the need for improving program directors’ understanding of the new accreditation requirement and increasing some programs’ clinical education for dental hygiene students in treating patients with IDD.

description: We study fixed assemblies of touching spheres that can individually rotate. From any initial state, sliding friction drives an assembly toward a slip-free rotation state. For bipartite assemblies, which have only even loops, this state has at least four degrees of freedom. For exactly four degrees of freedom, we analytically predict the final state, which we prove to be independent of the strength of sliding friction, from an arbitrary initial one. With a tabletop experiment, we show how to impose any slip-free rotation state by only controlling two spheres, regardless of the total number.

Τα αποτελέσματα ανέδειξαν ότι στις σχολικές μονάδες στις οποίες η διεύθυνση δίνει κίνητρα, εμπιστεύεται τα μέλη της και ενθαρρύνει πρωτοβουλίες, οι επιδόσεις των μαθητών τους ήταν υψηλότερες και οι στόχοι του σχολείου επιτυγχάνονταν στο μέγιστο βαθμό.
Side information in robust principal component analysis: algorithms and applications
Creators: name: Xue, Niannan
Publisher: name: Imperial College London
Year: 2019

description: Dimensionality reduction and noise removal are fundamental machine learning tasks that are vital to artificial intelligence applications. Principal component analysis has long been utilised in computer vision to achieve the above mentioned goals. Recently, it has been enhanced in terms of robustness to outliers in robust principal component analysis. Both convex and non-convex programs have been developed to solve this new formulation, some with exact convergence guarantees. Its effectiveness can be witnessed in image and video applications ranging from image denoising and alignment to background separation and face recognition. However, robust principal component analysis is by no means perfect. This dissertation identifies its limitations, explores various promising options for improvement and validates the proposed algorithms on both synthetic and real-world datasets. Common algorithms approximate the NP-hard formulation of robust principal component analysis with convex envelopes. Though under certain assumptions exact recovery can be guaranteed, the relaxation margin is too big to be squandered. In this work, we propose to apply gradient descent on the Burer-Monteiro bilinear matrix factorisation to squeeze this margin given available subspaces. This non-convex approach improves upon conventional convex approaches both in terms of accuracy and speed. On the other hand, oftentimes there is accompanying side information when an observation is made. The ability to assimilate such auxiliary sources of data can ameliorate the recovery process. In this work, we investigate in-depth such possibilities for incorporating side information in restoring the true underlining low-rank component from gross sparse noise. Lastly, tensors, also known as multi-dimensional arrays, represent real-world data more naturally than matrices. It is thus advantageous to adapt robust principal component analysis to tensors. Since there is no exact equivalence between tensor rank and matrix rank, we employ the notions of Tucker rank and CP rank as our optimisation objectives. Overall, this dissertation carefully defines the problems when facing real-world computer vision challenges, extensively and impartially evaluates the state-of-the-art approaches, proposes novel solutions and provides sufficient validations on both simulated data and popular real-world datasets for various mainstream computer vision tasks.
Black Americans and Schizophrenia: Understanding Racial Disparities in Functioning
Creators: name: Merritt, Carrington Cheryse
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: Black Americans are diagnosed with schizophrenia spectrum disorders at more than twice the rate of White individuals and experience significantly worse outcomes following the diagnostic event. Yet, little research to date has attempted to understand what specific factors contribute to worse functional outcomes among Black Americans with schizophrenia. The current study aims to broaden the current literature on such racial differences in functioning by using data from a double-blind, randomized treatment study to (1) examine baseline racial differences in established predictors of functioning (i.e., neurocognition, social cognition, and symptom severity); (2) investigate whether race moderates the strength of the relationship between these predictors and functioning at baseline; and (3) explore whether there are racial differences in the effectiveness of a novel psychopharmacological intervention of intranasal oxytocin in improving functioning among Black and White individuals with schizophrenia. Results revealed a significant difference in neurocognition at baseline as measured by the RBANS, with Black participants performing more poorly than White participants. No racial differences in measures of social cognition or symptom severity were observed. In addition, at baseline, race was found to moderate the relationship between PANSS-rated general symptoms and functioning measured by the SLOF but did not influence the relationship between other predictors and functioning outcomes. Finally, results indicated that race does not moderate the impact of oxytocin on functioning, social cognition, and symptom severity. Implications of these findings and suggestions for future work aimed at understanding racial disparities in functioning among Black and White Americans with schizophrenia are discussed.

description: A link between the semiclassical Einstein equation and a maximal vacuum entanglement hypothesis is established. The hypothesis asserts that entanglement entropy in small geodesic balls is maximized at fixed volume in a locally maximally symmetric vacuum state of geometry and quantum fields. A qualitative argument suggests that the Einstein equation implies validity of the hypothesis. A more precise argument shows that, for first-order variations of the local vacuum state of conformal quantum fields, the vacuum entanglement is stationary if and only if the Einstein equation holds. For nonconformal fields, the same conclusion follows modulo a conjecture about the variation of entanglement entropy.

Improving outcomes following complex foot and ankle injuries
Creators: name: McMenemy, Louise
Publisher: name: Imperial College London
Year: 2020

description: Foot and ankle injuries are severely disabling for military personnel who are conditioned to undertake impact activities. Following injury, performance and patient-reported outcomes have been shown to improve for amputees compared to limb-salvage military patients. A novel custom-made ankle foot orthosis may provide improved outcomes for limb-salvage patients. Initial results with the orthosis demonstrate improved performance and patient-reported outcomes at 2-year follow-up and a reduction in the number of personnel pursuing amputation. The orthosis, however, does not work for all foot and ankle injuries. This work sought to define the indications for prescription and create a clinical decision tool to facilitate evidence-based prescription. The outcomes for UK military personnel with complex foot and ankle injuries who underwent rehabilitation prior to the introduction of the orthosis were investigated. Over 50% of the cohort underwent amputation with improved performance outcomes for amputees compared to limb-salvage patients. Following the introduction of the orthosis, a reduction in amputation and improvement in physical performance measures were seen. Patients with a pain-specialist diagnosis of chronic pain did not benefit from prescription of the orthosis, whereas patients with primarily a nerve injury diagnosis did. Using injury characteristics alone, however, was found to be unable to predict outcome for all injured personnel. Therefore, biomechanical measures were examined. Gait analysis of patients prior to prescription of an orthotic was conducted. Patients with a negative symmetry index of more than 20% for power generation at pre-swing were found to benefit from prescription of the orthosis in the absence of an ipsilateral injury. This is the most complete investigation of UK personnel prescribed a novel orthosis following foot and ankle injury. This analysis facilitated the production of a clinical decision tool. The tool now requires validation and can be used to counsel foot and ankle injury patients on whether they may benefit from prescription of this orthosis.

description: Measuring the morphological parameters of galaxies is a key requirement for studying their formation and evolution. Surveys such as the Sloan Digital Sky Survey (SDSS) have resulted in the availability of very large collections of images, which have permitted population-wide analyses of galaxy morphology. Morphological analysis has traditionally been carried out mostly via visual inspection by trained experts, which is time-consuming and does not scale to large ($\gtrsim10^4$) numbers of images. Although attempts have been made to build automated classification systems, these have not been able to achieve the desired level of accuracy. The Galaxy Zoo project successfully applied a crowdsourcing strategy, inviting online users to classify images by answering a series of questions. Unfortunately, even this approach does not scale well enough to keep up with the increasing availability of galaxy images. We present a deep neural network model for galaxy morphology classification which exploits translational and rotational symmetry. It was developed in the context of the Galaxy Challenge, an international competition to build the best model for morphology classification based on annotated images from the Galaxy Zoo project. For images with high agreement among the Galaxy Zoo participants, our model is able to reproduce their consensus with near-perfect accuracy ($> 99\%$) for most questions. Confident model predictions are highly accurate, which makes the model suitable for filtering large collections of images and forwarding challenging images to experts for manual annotation. This approach greatly reduces the experts' workload without affecting accuracy. The application of these algorithms to larger sets of training data will be critical for analysing results from future surveys such as the LSST.

description: In this letter, we discuss a versatile, fully-reconfigurable experimental platform for the investigation of phononic phenomena in metamaterial architectures. The approach revolves around the use of 3D laser vibrometry to reconstruct global and local wavefield features in specimens obtained through simple arrangements of LEGO$^{\circledR}$ bricks on a thin baseplate. The agility by which it is possible to reconfigure the brick patterns into a nearly endless spectrum of topologies makes this an effective approach for rapid experimental proof of concept, as well as a powerful didactic tool, in the arena of phononic crystals and metamaterials engineering. We use our platform to provide a compelling visual illustration of important spatial wave manipulation effects (waveguiding and seismic isolation), and to elucidate fundamental dichotomies between Bragg-based and locally resonant bandgap mechanisms.
NEAR-INFRARED SPECTROSCOPY TO ASSESS EXERCISE-INDUCED CHANGES IN SKELETAL MUSCLE OXYGENATION IN PATIENTS WITH SOFT TISSUE SARCOMA: A PRELIMINARY INVESTIGATION

description: The initial purpose of this study was to examine the effects of single-joint resistance exercise on NIRS measurements, tumor necrosis percentage, functionality, and the rate of wound complications in patients with STS of the extremities undergoing preoperative radiation.  Due to extraneous circumstances, only two patients were able to complete study-related activities; therefore, the revised purpose of this preliminary study was to report demographic data on all parameters and assess the feasibility of the current protocol in order to guide subsequent research. Although no statistical analyses were performed, exercised-induced changes in blood volume were reported. Feasibility was evaluated on 8 established benchmarks: acceptability, demand, implementation, practicality, adaptation, integration, expansion, and limited-efficacy testing. Ultimately, it was determined that the current protocol is feasible for patients with soft tissue sarcoma below the knee in the lower limb.

Protection of national and state interests in the field of food security is included in the complex of problems of national security and has become one of the most acute problems of the 21st century, which requires a thorough discussion in order to ensure security and real sovereignty of the Russian Federation. The author discloses the essence of such notions as 'security', 'national security', 'food security'. The author provides interpretation of the term 'food security' as ability of the country irrespective of international situation to provide all layers of the population with an access to safe, highquality food in the amount necessary for active and healthy life without cutting state food reserves.

description: Dark Matter experiments are recently focusing their detection techniques in low-mass WIMPs, which requires the use of light elements and low energy threshold. In this context, we present the TREX-DM experiment, a low background Micromegas-based TPC for low-mass WIMP detection. Its main goal is the operation of an active detection mass $\sim$0.300 kg, with an energy threshold below 0.4 keVee and fully built with previously selected radiopure materials. This article describes the actual setup, the first results of the comissioning in Ar+2\%iC$_4$H$_{10}$ at 1.2 bar and the future updates for a possible physics run at the Canfranc Underground Laboratory in 2016. A first background model is also presented, based on Geant4 simulations and a muon/electron discrimination method. In a conservative scenario, TREX-DM could be sensitive to DAMA/LIBRA and other hints of positive WIMPs signals, with some space for improvement with a neutron/electron discrimination method or the use of other light gases.

Energy demand forecasting

description: In this dissertation, a pre-trained model for electricity demand forecasting, is presented. With the method of transfer learning it can be implemented in cases of unknown or limited data and make good predictions. The model was trained and evaluated in a combination of energy and weather data from European countries that were taken from an open platform for power system modelling: OPSD. Various neural network models were built, trained, and evaluated across 27 nations. The finalized best neural network was then contrasted with models using the Exponential Smoothing and the Theta method, as well as a basic neural network for each country that was specifically trained and tested for that nation. The proposed pre-trained model is also evaluated with unseen data from one country, and cases of inadequate data from this country are also looked at. It is also compared with a simple CNN and a model that shares the same architecture as the pre-trained model, in order to determine if the results are due to the large architecture of the model or if they occur from the transfer learning to other countries.

description: Impaired performance in verbal fluency (VF) tasks is a frequent observation in Parkinson's disease (PD). As to the nature of the underlying cognitive deficit, it is commonly attributed to a frontal-type dysexecutive syndrome due to nigrostriatal dopamine depletion. Whereas dopaminergic medication typically improves VF performance in PD, e.g., by ameliorating impaired lexical switching, its effect on semantic network activation is unclear. Data from priming studies suggest that dopamine causes a faster decay of semantic activation spread. The aim of the current study was to examine the impact of dopaminergic medication on the dynamic change of word frequency during VF performance as a measure of semantic spreading activation. To this end, we performed a median split analysis of word frequency during phonemic and semantic VF task performance in a PD group tested while receiving dopaminergic medication (ON) as well as after drug withdrawal (i.e., OFF), and in a sample of age-matched healthy volunteers (both groups n = 26). Dopaminergic medication in the PD group significantly affected phonemic VF with improved word production as well as increased error-rates. The expected decrease of word frequency during VF task performance was significantly smaller in the PD group ON medication than in healthy volunteers across semantic and phonemic VF. No significant group-difference emerged between controls and the PD group in the OFF condition. The comparison between both treatment conditions within the PD group did not reach statistical significance. The observed pattern of results indicates a faster decay of semantic network activation during lexical access in PD patients on dopaminergic medication. In view of improved word generation, this finding is consistent with a concept of more focused neural activity by an increased signal-to-noise ratio due to dopaminergic neuromodulation. However, the effect of dopaminergic stimulation on VF output suggests a trade-off between these beneficial effects and increased error-rates.

description: We give a characterization for the existence of a holomorphic interpolant on the unit polydisc $\mathbb{D}^n,$ $n\geq 2,$ for prescribed three-point Pick--Nevanlinna data. One of the key steps is a characterization for the existence of an interpolant that is a rational inner function on $\mathbb{D}^n.$ The latter reduces the search for a three-point interpolant to finding a single rational inner function that satisfies a type of positivity condition and arises from a polynomial of a very special form. This in turn relies on a pair of results, which are of independent interest, on the factorization of rational inner functions.

Understanding and engineering cofactor metabolism: a quest for improved biochemical production
Creators: name: De Arroyo Garcia, Laura
Publisher: name: Imperial College London

description: In the field of metabolic engineering, where cells are treated as “factories” that synthesise industrial compounds, it is essential for cell metabolism to accommodate the energy and re- dox cofactor demands of synthetic pathways. A balanced supply and consumption of ATP and NAD(P)H directly influences biotechnological performance. This study develops computational and experimental frameworks to explore how ATP and NAD(P)H limit the yield of synthetic pathways during bioproduction. Constraint-based modelling was used to develop a novel computational protocol, CBA (Co- factor Balance Assessment), which tracks how ATP and NAD(P)H contribute to cell target production, as opposed to cell maintenance, biomass and waste release, in the presence of a synthetic pathway. Using butanol pathways (a non-native product in E.coli) with varying cofactor demands, CBA discerned the network-wide effects of cofactor variations on butanol yield. Results indicate that yields could be boosted by up to 13% if the introduced pathway is balanced both in terms of energy and redox. CBA simplified cofactor balance assessments and provided insights into how to improve the efficiency of recombinant strains. Physiological and metabolic responses to cofactor perturbations were also experimentally assessed. The predominant phenotypes of strains harbouring the ATP synthase and PCK knockouts included high glycolytic flux, lower biomass and ATP. These strains were used to improve ethanol production, resulting in yields 10% and 29% higher than the WT overproducing ethanol and reaching over 70% of the theoretical maximum. The low but positive ATP yields boosted ethanol production and minimised unrestricted growth. This research posits that early-stage in silico cofactor usage profiling serves as an instrument to select better performing pathways. Significant yield improvements can be achieved experimentally with a small number of cofactor-driven modifications that reduce the waste of cofactors, illustrating the potential of these strains as platforms to improve bioproduction of cofactor-neutral or cofactor-surplus synthetic pathways.

description: Graphene bilayers and trilayers consisting of monolayers twisted at just the right angle have been shown to be superconducting. To acquire a unified understanding of superconductivity in these moiré superlattices, it is desirable to increase the number of known graphene moiré superconductors. Zhang et al. fabricated samples consisting of three, four, and five graphene layers that were twisted with respect to each other in an alternating sequence. These graphene multilayers were coupled to an underlying monolayer of tungsten diselenide. The researchers observed robust superconductivity in all three types of samples, with the superconducting portion of the phase diagram becoming more prominent as the number of layers increased.

description: Growing literature on the relevance of text and artifacts such as media and magazine has revealed the role of culinary programs and celebrity chefs in stimulating changing in patterns of consumption. It has been noticed that the active work of chefs through TV program, their importance in addressing global consumer culture and in disseminating attractive models for consumption behavior has developed in recent years. The paper underlines the role played from both media and celebrity chefs in influencing consumer behavior and transition in food habits. More precisely, by putting forward an empirical test, we try to emphasize the effectiveness of TV culinary programs in determining Veblen’s processes of emulation and Bordieu’s “distinct” food attitudes. In particular, by referring to Bordieu’s concept of distinction, we investigate on processes of modification and transition in food habits. The results confirm relevant differences between consumers watching culinary programs and other consumers in performing different purchasing and consumer aptitudes.

description: Hall effect and magnetoresistance have been measured on single crystals of the parent phase NaFeAs under a uniaxial pressure. Although significant difference of the in-plane resistivity $ρ_{xx}(I\parallel a)$ and $ρ_{xx}(I\parallel b)$ with the uniaxial pressure along $b$-axis was observed, the transverse resistivity $ρ_{xy}$ shows a surprisingly isotropic behavior. Detailed analysis reveals that the Hall coefficient $R_\mathrm{H}$ measured in the two orthogonal configurations ($I\parallel a$-axis and $I\parallel b$-axis) coincide very well and exhibit a deviation from the high temperature background at around the structural transition temperature $T_{\mathrm{s}}$. Furthermore, the magnitude of $R_\mathrm{H}$ increases remarkably below the structural transition temperature. This enhanced Hall coefficient is accompanied by the non-linear transverse resistivity versus magnetic field and enhanced magnetoresistance, which can be explained very well by the two band model with anisotropic mobilities of each band. Our results together with the two band model analysis clearly show that the anisotropic in-plane resistivity in the nematic state is closely related to the distinct quasiparticle mobilities when they are moving parallel or perpendicular to the direction of the uniaxial pressure.
