title: Αυτορυθμιζόμενος έλεγχος κυκλοφορίας σταθερού χρόνου
Creators: name: Φαραντουρης Σπυριδων
Publisher: name: Technical University of Crete
Year: 2018

description: Ο σχεδιασμός και η ανάπτυξη των συστημάτων ελέγχου, όσον αφορά τα ευφυή συστήματα μεταφοράς (ΕΣΜ) γίνεται με μη αυτοματοποιημένες διαδικασίες , οι οποίες πέρα από την πνευματική κούραση που επιφέρουν, απαιτούν και αρκετό χρόνο υλοποίησης. Στις περισσότερες περιπτώσεις αυτό παρατηρείται καθ’ όλη τη διάρκεια ζωής ενός ΕΣΜ.
Με αφορμή το παραπάνω πρόβλημα αναπτύχθηκε πριν μερικά χρόνια ένας νέος αλγόριθμος με σκοπό να επιτευχθεί η αυτόματη ρύθμιση και παραμετροποίηση των συστημάτων αυτών. Ο αλγόριθμος Adaptive Fine-Tuning (AFT) πετυχαίνει σημαντική βελτίωση των επιδόσεων των συστημάτων ελέγχου αλλά και την αντιστάθμιση των συνεπειών από τις συνεχείς αλλαγές που δέχεται ένα ΕΣΜ από εξωτερικούς ή εσωτερικούς παράγοντες.
Η εφαρμογή της τεχνολογίας αυτής απαιτεί τη συλλογή δεδομένων από το δίκτυο στο οποίο θα εφαρμοστεί. Η συλλογή των δεδομένων για τη λειτουργία του AFT μπορεί να επιτευχτεί είτε μέσω εγκατάστασης υποδομών (π.χ φωρατές ή κάμερες), είτε μέσω σημάτων που λαμβάνονται από αισθητήρες gps κινητών τηλεφώνων, τα οποία θα μας δίνουν τα απαραίτητα στοιχεία των συνδεδεμένων οχημάτων (connected-vehicles). Για την αποφυγή εγκαταστάσεων και την μείωση του κόστους ο AFT επιλέγουμε να λειτουργεί με την χρήση σημάτων από αισθητήρες gps, αφού αποτελεί μια μέθοδο φθηνή αλλά και με αυξημένη ακρίβεια σε σχέση με τις συμβατικές μεθόδους συλλογής δεδομένων.
Σε αυτή τη διπλωματική παρουσιάζουμε και αναλύουμε τα αποτελέσματα που έδωσε ο αλγόριθμος AFT από την εφαρμογή του σε προσομοιώσεις διάφορων δικτύων, με τη χρήση του προσομοιωτή AIMSUN.

description: We investigate the doping of AA-stacked graphene bilayers. Applying a mean field theory at zero temperature we find that, at half-filling, the bilayer is an antiferromagnetic insulator. Upon doping, the homogeneous phase becomes unstable with respect to phase separation. The separated phases are an undoped antiferromagnetic insulator and a metal with a non-zero concentration of charge carriers. At sufficiently high doping, the insulating areas shrink and disappear, and the system becomes a homogeneous metal. The conductivity changes drastically upon doping, so the bilayer may be used as a switch in electronic devices. The effects of finite temperature are also discussed.

inter-observer repeatability

description: The technical study aimed at evaluating the prevalence and the inter-observer repeatability of the most valid and feasible animal-based indicators of the state of consciousness after waterbath stunning in turkeys before bleeding (tonic seizure, breathing, spontaneous blinking, and vocalisation) and during bleeding (wing flapping, breathing, spontaneous swallowing, and head shaking). In addition, correlations among them were computed to better understand their relationship and offer better insight on reliability of indicators. This was aimed at proposing a refined list of indicators that can be used in commercial slaughterhouses ensuring consistency of assessments. Moreover, the effectiveness of stunning according to different combinations of waterbath electrical key parameters (frequency and current) used in different commercial slaughterhouses was assessed in order to provide general recommendations.

description: Twin-screw wet granulation offers the possibility to granulate continuously. A drying step after wet granulation is required to realize a full continuous manufacturing line. Aim of this study was to gain insights into the drying behavior of a continuous vibrated fluidized bed dryer intended for pharmaceutical research and development. A Design of Experiment was conducted to examine the influence of process parameters during the drying of granules using drying temperature, air flow, and vibration acceleration as factors. The obtained temperature and humidity profiles during the drying of lactose-MCC and mannitol granules displayed the first and second drying stage which is spatially resolved. With a higher drying temperature or higher air flow, the second drying stage was achieved earlier. An increase in vibration acceleration shortened the residence time and by this, the second drying stage was reached later at a lower granule temperature and thus higher residual moisture of the granules. Formulation-dependent impact of the drying parameters was observed as lactose-MCC led to smaller granules when increasing the temperature or air flow.

description: To enhance the oral bioavailability of atorvastatin calcium (ATV), a novel solidified micelle (S-micelle) was developed. Two surfactants, Gelucire 48/16 (G48) and Tween 20 (T20), were employed for micelle formation, and two solid carriers (SC), Florite PS-10 (FLO) and Vivapur 105 (VP105), were selected as solid carriers. The S-micelle was optimized using a Box-Behnken design with three independent variables, including G48:T20 (X1, 1.8:1), SC:G48 + T20 (X2, 0.65:1), and FLO:VP105 (X3, 1.4:0.6), resulting in a droplet size (Y1) of 198.4 nm, dissolution efficiency at 15 min in the pH 1.2 medium (Y2) of 47.6%, Carr’s index (Y3) of 16.9, and total quantity (Y4) of 562.5 mg. The optimized S-micelle resulted in good correlation showing percentage prediction values less than 10%. The optimized S-micelle formed a nanosized dispersion in the aqueous phase, with a higher dissolution rate than raw ATV and crushed Lipitor®. The optimized S-micelle improved the relative bioavailability of oral ATV (25 mg equivalent/kg) in rats by approximately 509 and 271% compared to raw ATV and crushed Lipitor®, respectively. In conclusion, the optimized S-micelle possesses great potential for the development of solidified formulations for improved oral absorption of poorly water-soluble drugs.

description: A thorough analysis of multicolour CCD observations of two modulated RRab-type variables, XY And and UZ Vir is presented. These Blazhko stars show relatively simple light-curve modulation with the usual multiplet structures in their Fourier spectra. One additional, independent frequency with linear-combination terms of the pulsation frequency is also detected in the residual spectrum of each of the two stars. The amplitude and phase relations of the triplet components are studied in detail. Most of the epoch-independent phase differences show a slight, systematic colour dependence, however, these trends have the opposite sign in the two stars. The mean values of the global physical parameters and their changes with Blazhko phase are determined utilizing the Inverse Photometric Method (IPM). The modulation properties and the IPM results are compared for the two variables. The pulsation period of XY And is the shortest when its pulsation amplitude is the highest, while UZ Vir has the longest pulsation period at this phase of the modulation. Despite this opposite behaviour, the phase relations of their mean-physical-parameter variations are similar. These results are not in accord with the predictions of the Blazhko model of Stothers (2006, ApJ, 652, 643).

A Brief Review on Gestational Diabetes Mellitus

Subjects: Gestational Diabetes Mellitus (GDM)
pregnancy

hyperglycaemia

description: GDM (gestational diabetes mellitus) is a common metabolic condition that manifests itself in varying degrees of severity before or during pregnancy. It has been linked to negative maternal and newborn outcomes. Globally, the prevalence of GDM is rising, along with the rise in the incidence of obesity and type 2 diabetes mellitus. It is critical to detect and treat GDM as soon as possible in order to minimise or eliminate difficulties for both the mother and the foetus. Globally, there is indeed a lack of consistency in evaluating and detecting GDM. This article discusses the most recent developments in the diagnosis and treatment of GDM. For the greatest outcomes, treatment must be tailored to the person, combining medical nutrition therapy, supplemental food, and exercise. If these strategies fail to regulate blood glucose levels, pharmacologic therapies, namely insulin and its analogues, should be implemented. The treatment with pharmacologic interventions has an important role on lowering the complications related to GDM. Other oral antihyperglycemic drugs like Metformin and Glyburide are also considered in light of emerging information about their safety and efficacy during pregnancy.

description: We study the similarities of jet-medium interactions in several quite different astrophysical systems using 2D and 3D hydrodynamical numerical simulations, and find many similarities. The systems include cooling flow (CF) clusters of galaxies, core-collapse supernovae (CCSNe), planetary nebulae (PNe), and common envelope (CE) evolution. The similarities include hot bubbles inflated by jets in a bipolar structure, vortices on the sides of the jets, vortices inside the inflated bubbles, fragmentation of bubbles to two and more bubbles, and buoyancy of bubbles. The activity in many cases is regulated by a negative feedback mechanism. Namely, higher accretion rate leads to stronger jet activity that in turn suppresses the accretion process. After the jets power decreases the accretion resumes, and the cycle restarts. In the case of CF in galaxies and clusters of galaxies we also study the accretion process, which is most likely by cold clumps, i.e., the cold feedback mechanism. In CF clusters we find that heating of the intra-cluster medium (ICM) is done by mixing hot shocked jet gas with the ICM, and not by shocks. Our results strengthen the jet feedback mechanism (JFM) as a common process in many astrophysical objects.

description: We place limits on semiclassical fluctuations that might be present in the primordial perturbation spectrum. These can arise if some signatures of pre-inflationary features survive the expansion, or could be created by whatever mechanism ends inflation. We study two possible models for such remnant fluctuations, both of which break the isotropy of CMB on large scales. We first consider a semiclassical fluctuation in one Fourier mode of primordial perturbations. The second scenario we analyze is a semiclassical Gaussian bump somewhere in space. These models are tested with the seven-year WMAP data using a Markov Chain Monte Carlo Bayesian analysis, and we place limits on these fluctuations. The upper bound for the amplitude of a fluctuation in a single Fourier mode is a<=10^(-4), while for the Gaussian bump a<=10^(-3).

description: We study low-frequency noise in current passing through quantum point contacts fabricated from several GaAs/AlGaAs heterostructures with different layer structures and fabrication processes. In contrast to previous reports, there is no gate-dependent random telegraph noise (RTN) originating from tunneling through a Schottky barrier in devices fabricated using the standard low-damage process. Gate-dependent RTN appears only in devices fabricated with a high-damage process that induces charge trap sites. We show that the insertion of AlAs/GaAs superlattices in the AlGaAs barrier helps to suppress trap formation. Our results enable the fabrication of damage-resistant and thus low-noise devices.

description: Solid-state topological insulating phases, characterized by spin-momentum locked edge modes, provide a powerful route for spin and charge manipulation in electronic devices. We propose to control charge and spin transport in the helical edge modes by electrically switching the topological insulating phase in a HgTe/CdTe double quantum well device. We introduce the concept of a topological field-effect-transistor and analyze possible applications to a spin battery, which also realize a set up for an all-electrical investigation of the spin-polarization dynamics in metallic islands.

description: Dry-ageing of fresh meat is a natural processing strategy. It focuses on developing the signature, dry-aged meat flavour to satisfy growing consumer demands for exceptional eating experiences. Dry-aged meat is a niche product preferred by meat purveyors for its tenderness and unique flavours, such as intense nutty, roasted, earthy, buttery and umami flavours. Research focus on dry-ageing has significantly increased in the last 5-10 years as scientists and the meat industry aim to understand the key advantages of dry-ageing, and how dry-ageing can provide alternative merchandising opportunities for local and export markets. Traditionally, dry-ageing is done by hanging primal or subprimal meat cuts, or placing them on shelves, in an ageing chamber (Figure 1). This allows critical elements of meat ageing to be controlled, including temperature, air velocity and relative humidity (RH). The typical process is to dry-age at refrigerator temperatures (0-4 °C), with effective air circulation and an intermediate RH (e.g. 70-85%), for a minimum of three weeks to develop the characteristic dry-aged meat flavour. Dry-ageing can also be seen as “ageing under drying conditions”. A series of physical and biochemical reactions take place during the dry-ageing process, such as dehydration, oxidation, proteolysis, lipolysis and growth of microorganisms (Zhang, Yoo, Ross, & Farouk, 2022). These develop the unique quality of dry-aged meat. Studying dry-ageing of red meat is one of the unique capabilities in AgResearch’s Food Processing and Technology team. Early career meat scientist, Dr Renyu Zhang, established the mechanisms for developing unique dry-aged meat flavour based on his Ph.D. research (Zhang et al., 2022). Renyu’s research priority is advancing knowledge of dry-ageing, while also developing viable strategies to support the meat and food service industries to produce dry-aged meat with more consistent quality, tailorable flavour and lower costs. This mini review provides an overview of recent dry-ageing research at AgResearch.

description: Background: Despite significant family caregiver (FCG) burnout, there are currently no tested interventions to support the FCG role after left ventricular assist device (LVAD) implantation or formalized training for clinicians to support FCGs. Objective: We adapted the existing ENABLE (Educate, Nurture, Advise Before Life Ends) intervention to LVAD clinicians and FCGs and assessed clinical implementation and dissemination. Methods: ENABLE-LVAD is an interactive, self-paced clinician training coupled with FCG-facing guidebooks and resources. Implementation and dissemination were evaluated by the RE-AIM(reach, effectiveness, adoption, implementation, andmaintenance) framework. Results: As of May 2023, 187 clinicians registered for the training, and 41 completed all modules (22.0% completion rate). Of those who completed the training and responded to a 6-month survey, one-third (n = 10, 33.3%) used ENABLE-LVAD with FCGs, and 100%of those planned to continue using it. The primary barrier to completing the training was time. Conclusions: The ENABLE-LVAD clinician training was successfully disseminated and implemented as a useful resource to support LVAD FCGs.

title: Landscape of Molecular Events Regulating Multiple Myeloma Cell Responses to Natural Killer Cells
Creators: name: Gandolfi, Sara
Publisher: name: The Open University
Year: 2023

description: Immunotherapy has remarkably changed the treatment paradigm in hematologic malignancies and natural killer (NK) cell therapy represents an attractive option. However, there have been, to our knowledge, no genome-wide CRISPR-based screens to identify candidate markers of response to NK cells in multiple myeloma (MM), which remains incurable. Furthermore, the molecular markers determining cancer cell resistance to NK cells, especially in the context of tumor interaction with the bone marrow (BM) stromal microenvironment remain incompletely understood but have major translational relevance. In this study we sought to address this void by applying genome-scale loss of-function and gain-of-function CRISPR-based screens in MM cell lines to interrogate the markers of cancer cell resistance at a functional level. The data showed that NK cell response of MM cells is modulated by activation of several metabolic and homeostatic genes, receptor kinases, and membrane-bound proteins of the mucin family, while genes whose LOF or GOF is associated with worse clinical outcome seemed not to impact the response. We then integrated such data with those obtained by quantifying the NK cell responsiveness of 70 molecularly annotated hematologic cancer cell lines, in presence or in absence of BM stromal cells. Two distinct clusters of cell lines were identified, sensitive and resistant to NK cells, which showed an overall markedly decreased responsiveness in presence of stroma, while retaining their distinct clustering. RNA-seq data showed no differentially expressed genes at baseline clearly allowing to predict NK cell response. However, the two clusters differed at a pathway level, with an enrichment of PI3K-AKT, TNFR2, HDAC class I gene signatures and the antigen presentation machinery genes in the resistant cluster, consistent with data from LOF CRISPR studies. Overall, this study provides a comprehensive landscape of the mechanisms regulating MM cells response to NK cells, with translational implications for future biomarker-oriented applications of NK cell-based adoptive therapies.

description: Motivated by the need for communication of coherent state-based qubits in quantum computers, we introduce a method for perfect transferring of an arbitrary superposition of coherent states between two distant nodes of a linear array of three semiconductor QDs. The QDs trapped in a system of coupled cavities. In this method, the field mode of the cavities, as the resource of transferring of quantum states, are only virtually excited which minimizes the effect of decoherence due to photon loss.

description: We establish the relationship between volumes of flow polytopes associated to signed graphs and the Kostant partition function. A special case of this relationship, namely, when the graphs are signless, has been studied in detail by Baldoni and Vergne using techniques of residues. In contrast with their approach, we provide entirely combinatorial proofs inspired by the work of Postnikov and Stanley on flow polytopes. As a fascinating special family of flow polytopes, we study the Chan-Robbins-Yuen polytopes. Motivated by the beautiful volume formula $\prod_{k=1}^{n-2} Cat(k)$ for the type $A_n$ version, where $Cat(k)$ is the $k$th Catalan number, we introduce type $C_{n+1}$ and $D_{n+1}$ Chan-Robbins-Yuen polytopes along with intriguing conjectures pertaining to their properties.

description: We report on the experimental and theoretical study of the spatial fluctuations of the local density of states (EM-LDOS) and of the fluorescence intensity in the near-field of a gold nanoantenna. EM-LDOS, fluorescence intensity and topography maps are acquired simultaneously by scanning a fluorescent nanosource grafted on the tip of an atomic force microscope at the surface of the sample. The results are in good quantitative agreement with numerical simulations. This work paves the way for a full near-field characterization of an optical nanoantenna.

description: Based on DFT, MP2, and hybrid GGA: MPW1k calculations for an acid-catalyzed hydrolysis of nine Kirby’s N-alkylmaleamic acids, a number of atenolol prodrugs were designed. A linear correlation of the calculated and experimental rate values for the nine Kirby’s N-alkylmaleamic acids has established credible basis for designing atenolol prodrugs that are bitterless, are stable in neutral aqueous solutions, and have the potential to release the parent drug in a sustained release manner. For example, based on the calculated B3LYP/6-31 G (d,p) rates, the predicted t1/2 values for atenolol prodrugs ProD 1-ProD 2 at pH 2 were 65.3 hours and 11.8 minutes, respectively. In vitro kinetic study of atenolol prodrug ProD 1 revealed that the t1/2 was largely affected by the pH of the medium. The determined t1/2 values in 1N HCl, buffer pH 2, and buffer pH 5 were 2.53, 3.82, and 133 hours, respectively.

description: The dynamics and stability of brittle cracks are not yet fully understood. Here we use the Willis-Movchan 3D linear perturbation formalism [J. Mech. Phys. Solids {\bf 45}, 591 (1997)] to study the out-of-plane stability of planar crack fronts in the framework of linear elastic fracture mechanics. We discuss a minimal scenario in which linearly unstable crack front corrugations might emerge above a critical front propagation speed. We calculate this speed as a function of Poisson's ratio and show that corrugations propagate along the crack front at nearly the Rayleigh wave-speed. Finally, we hypothesize about a possible relation between such corrugations and the long-standing problem of crack branching.

description: We study the capacity of heterogeneous distributed storage systems under repair dynamics. Examples of these systems include peer-to-peer storage clouds, wireless, and Internet caching systems. Nodes in a heterogeneous system can have different storage capacities and different repair bandwidths. We give lower and upper bounds on the system capacity. These bounds depend on either the average resources per node, or on a detailed knowledge of the node characteristics. Moreover, we study the case in which nodes may be compromised by an eavesdropper, and give bounds on the system secrecy capacity. One implication of our results is that symmetric repair maximizes the capacity of a homogeneous system, which justifies the model widely used in the literature.
