Εξαρτησιογόνα

description: Οι παραισθησιογόνες και εξαρτησιογόνες ουσίες αποτελούν ουσίες που χρησιμοποιούνται από την αρχαιότητα μέχρι και σήμερα. Οι ουσίες αυτές ελκύουν το άτομο σε πολλαπλές χρήσεις και συγχρόνως μπορεί να του προκαλέσουν παραισθήσεις και σε μεγάλες δοσολογίες ενδέχεται να επέλθει ακόμη και ο θάνατος. Οι ουσίες αυτές χωρίζονται σε 7 βασικές κατηγορίες. Συνήθως αναφέρονται με τον όρο ναρκωτικές ουσίες καθώς περιλαμβάνονται ουσίες όπως η ηρωΐνη, η κοκαΐνη, το LSD κ.α.. Ωστόσο υπάρχουν εξαρτησιογόνα που καταναλώνονται μέσα από τα τρόφιμα. Κάποια από αυτά είναι η μυριστικίνη, η καφεΐνη, ακόμη και η ινδική κάνναβη έχει εισαχθεί σε πολλά φαγώσιμα σκευάσματα. Ο εργαστηριακός προσδιορισμός τους είναι μείζονος σημασίας, καθώς και δίνει τη δυνατότητα μελέτης της ουσίας αυτής. Επιπλέον μπορεί να ανιχνευτεί σε κλινικά δείγματα και σε δείγματα τροφίμων καλύπτοντας νομικές περιπτώσεις, όπως για παράδειγμα την διαλεύκανση μιας εγκληματικής ενέργειας ή ακόμη και την επεξήγηση ενός θανάτου. Η πιο συνήθης μέθοδος προσδιορισμού των παραισθησιογόνων και εξαρτησιογόνων ουσιών είναι η HPLC. Επιπλέον, χρησιμοποιούνται και άλλες τεχνικές όπως η τριχοειδής χρωματογραφία και η ηλεκτροφόρηση. Τέλος, έχουν γίνει προσπάθειες διερεύνησης των ουσιών αυτών και σε εναλλακτικά δείγματα, όπως δείγματα μαλλιών, σιέλου και ιδρώτα. Η προσπάθεια διερεύνησης νέων μεθόδων ανάλυσης των εξαρτησιογόνων και παραισθησιογόνων ουσιών, έχει δώσει πολύ θετικά αποτελέσματα στον επιστημονικό χώρο, προσπαθώντας την ανάπτυξη ταχύτατων, οικονομικότερων και πιο αξιόπιστων μεθόδων ανάλυσης. Η συνεχής επιστημονική εξέλιξη ενδέχεται να κατορθώσει να φθάσει στο σημείο οι αναλύσεις αυτές να αποτελούν αναλύσεις ρουτίνας για το εργαστήριο. Αν και με το πέρασμα των χρόνων οι μέθοδοι προσδιορισμού των εξαρτησιογόνων και παραισθησιογόνων ουσιών έχουν βελτιωθεί αρκετά, η HPLC παραμένει μια γρήγορη και αξιόπιστη επιλογή. Η χρήση εναλλακτικών δειγμάτων, επιτρέπει να ανοιχτούν νέοι ορίζοντες που αφορούν την διερεύνηση των ουσιών αυτών και να δώσουν λύση σε πολλές αιτίες ατυχημάτων ή ακόμη και θανάτων.

description: Η ανακάλυψη και η εφαρμογή των αντιβιοτικών για την πρόληψη και τη θεραπεία των ασθενειών, τόσο στην ιατρική όσο και την κτηνιατρική αποτέλεσε σταθμό στην ιατρική επιστήμη. Όμως η ευρεία και πολλές φορές αλόγιστη χρήση τους, έχει οδηγήσει σε ανησυχητική αύξηση των ανθεκτικών βακτηριακών στελεχών, δυσκολεύοντας έτσι την θεραπεία των λοιμώξεων. Το φαινόμενο της μικροβιακής αντοχής αποτελεί πλέον ένα από τα σοβαρότερα προβλήματα δημόσιας υγείας του 21ου αιώνα. Τα ανθεκτικά βακτήρια δεν εντοπίζονται μόνο στο περιβάλλον του νοσοκομείου. Βάσει της διεθνούς βιβλιογραφίας ανθεκτικοί μικροοργανισμοί εντοπίζονται συνεχώς στο υδάτινο περιβάλλον (όπως ποτάμια, λίμνες), στα λύματα και στο έδαφος. Σε αυτά τα ενδιαιτήματα ευνοείται η οριζόντια μεταφορά γονιδίων αντοχής, συμβάλλοντας στην περαιτέρω εξάπλωση των ανθεκτικών πληθυσμών. Επιπλέον, τα επιβαρυμένα ποτάμια (αποδέκτες λυμάτων) αποτελούν πηγή μόλυνσης από ανθεκτικά και πολύ-ανθεκτικά βακτήρια καθώς συχνά αξιοποιούνται για αρδευτικούς και ψυχαγωγικούς (ψάρεμα, κωπηλασία, κολύμπι) σκοπούς. Το βακτήριο Escherichia coli (E. coli) καθώς συγκαταλέγεται στους φυσιολογικούς άποικους του γαστρεντερικού σωλήνα των ανθρώπων και των άλλων θερμόαιμων ζώων, καταλήγει στο λύμα και μέσω αυτού στο υδάτινο οικοσύστημα. Αποτελεί βασικό και καθιερωμένο δείκτη πρόσφατης κοπρανώδους μόλυνσης των υδάτων. Επιπρόσθετα, είναι η πιο κοινή αιτία ουρολοιμώξεων και γαστρεντερίτιδων, τόσο στο νοσοκομειακό περιβάλλον όσο και στη κοινότητα. Επομένως η εμφάνιση ανθεκτικών και πολύ-ανθεκτικών στελεχών E. coli έχει προκαλέσει τεράστια ανησυχία στην επιστημονική κοινότητα. Για αυτό το λόγο, σκοπός της παρούσας διπλωματικής εργασίας ήταν η μοριακή ανίχνευση γονιδίων αντιμικροβιακής αντοχής σε στελέχη E. coli, τα οποία απομονώθηκαν τον Ιούλιο του 2020 από το Ποτάμι Έρκυνα της Λιβαδειάς, στο οποίο εκβάλει το λύμα της Μονάδας Επεξεργασίας Λυμάτων της περιοχής. Συνολικά απομονώθηκαν τριάντα ένα (31) στελέχη E. coli, τα οποία υποβλήθηκαν: α) σε έλεγχο μικροβιακής ευαισθησίας σε 18 ευρέως χρησιμοποιούμενα αντιβιοτικά, β) σε φυλογενετική ταξινόμηση με τη μοριακή μέθοδο του Phylogrouping και γ) σε έλεγχο παρουσίας γονιδίων αντοχής με την μέθοδο της PCR. Βάσει των αποτελεσμάτων η πλειοψηφία των στελεχών (23/31 ή 74,2%) εμφάνισε αντοχή σε τουλάχιστον ένα αντιβιοτικό παράγοντα ενώ σε 4 στελέχη ανιχνεύθηκαν γονίδια που προσδίδουν αντοχή σε καφαλοσπορίνες εκτεταμένου φάσματος. Σύμφωνα με τη φυλογενετική τυποποιητική μέθοδο, κατατάχθηκαν σε 4 ομάδες με την ομάδα A να είναι επικρατέστερη (20/31 ή 64,50%).

description: This note aims to subsume several apparently unrelated models under a common framework. Several examples of well-known quantum field theories are listed which are connected via stochastic quantization. We highlight the fact that the quantization method used to obtain the quantum crystal is a discrete analog of stochastic quantization. This model is of interest for string theory, since the (classical) melting crystal corner is related to the topological A-model. We outline several ideas for interpreting the quantum crystal on the string theory side of the correspondence, exploring interpretations in the Wheeler-De Witt framework and in terms of a non-Lorentz invariant limit of topological M-theory.

description: Cells of glioblastoma, the most frequent primary malignant brain tumor, are characterized by their rapid growth and infiltration of adjacent healthy brain parenchyma, which reflects their aggressive biological behavior. In order to maintain their excessive proliferation and invasion, glioblastomas exploit the innate biological capacities of the patients suffering from this tumor. The pathways involved in cell cycle regulation and apoptosis are the mechanisms most commonly affected. The following work reviews the regulatory pathways of cell growth in general as well as the dysregulated cell cycle and apoptosis relevant mechanisms observed in glioblastomas. We then describe the molecular targeting of the current established adjuvant therapy and present ongoing trials or completed studies on specific promising therapeutic agents that induce cell cycle arrest and apoptosis of glioblastoma cells.

description: The Karlsruhe Tritium Neutrino (KATRIN) experiment aims to make a precision measurement of the effective neutrino mass by leveraging the kinematics of tritium beta decay, with a 3-year sensitivity of 0.2eV (90% C.L.). Recent run campaigns, both in standard mode (using molecular tritium) and calibration mode (using 83mKr ), have provided a wealth of data. This data was analyzed using the CMKAT analysis framework, which models the integrated spectra using a convolution of the source decay physics and the experiment's response function. Additional information relating to construction and validation of CMKAT is included. Finally, results from fits to the second neutrino mass measurement campaign (KNM2) are presented, and confidence intervals on the extracted effective neutrino mass are constructed; selected systematic studies are included.

description: Τα τελευταία χρόνια υπάρχει ολοένα και μεγαλύτερο ενδιαφέρον για την έρευνα και τη μελέτη της επίδρασης του συναισθήματος στη μνήμη και τη μάθηση. Τα συναισθήματα, όπως είναι ήδη γνωστό, είναι στενά συνυφασμένα τόσο με τις προσωπικές όσο και με τις κοινωνικές εκφάνσεις της ζωής του ανθρώπου. Αποτελούν τη βάση για τη δημιουργία μνημών και αναμνήσεων καθώς είναι δυναμικά, κοινωνικά και εξαρτώνται από το περιβάλλον. Είναι αποτέλεσμα νευροφυσιολογικών λειτουργιών με έδρα τον εγκέφαλο και η κατανόησή τους συμβάλλει στη βέλτιστη αποκωδικοποίηση των δραστηριοτήτων του εγκεφάλου που συνδέονται με τη μνήμη και τη μάθηση. Η μάθηση, η οποία αναφέρεται σε νέες γνώσεις, τρόπους σκέψης και στην κατάκτηση νέων δεξιοτήτων, προηγείται της μνήμης. Κατ’ επέκταση, η μελέτη του νευροβιολογικού υπόβαθρου των συναισθημάτων και της επίδρασής τους στη μνημονική λειτουργία και τη μαθησιακή διαδικασία, συντελεί στην αποτελεσματικότερη μάθηση. Η συγκεκριμένη εργασία αποτελεί μία προσπάθεια βιβλιογραφικής διερεύνησης και μελέτης με στόχο να βοηθήσει στην κατανόηση της επίδρασης του συναισθήματος στη μάθηση και τη μνήμη, αλλά και στην προσέγγιση των λειτουργικών ρόλων που διαδραματίζουν διάφορες περιοχές του εγκεφάλου στο πλαίσιο της συναισθηματικής επεξεργασίας. Συνοψίζοντας, τα σύγχρονα βιβλιογραφικά δεδομένα σχετικά με τον αντίκτυπο του συναισθήματος στη μνημονική και μαθησιακή διαδικασία διατυπώνονται συμπεράσματα που αναφέρονται στις επιδράσεις του συναισθήματος που ενισχύουν ή παρεμποδίζουν τη μνήμη και τη μάθηση αντίστοιχα.

Minimum free-energy path of homogenous nucleation from the phase-field equation
Creators: name: Iwamatsu, Masao
Publisher: name: arXiv
Year: 2009
Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: The minimum free-energy path (MFEP) is the most probable route of the nucleation process on the multidimensional free-energy surface. In this study, the phase-field equation is used as a mathematical tool to deduce the minimum free-energy path (MFEP) of homogeneous nucleation. We use a simple square-gradient free-energy functional with a quartic local free-energy function as an example and study the time evolution of a single nucleus placed within a metastable environment. The time integration of the phase-field equation is performed using the numerically efficient cell-dynamics method. By monitoring the evolution of the size of the nucleus and the free energy of the system simultaneously, we can easily deduce the free-energy barrier as a function of the size of the sub- and the super-critical nucleus along the MFEP.

description: Thermische Gebäudesimulationen eignen sich zur objektiven Bewertung der Hitzebelastung in Gebäuden. Die Einschätzung der Hitzerobustheit über Gebäudesimulationen hängt jedoch sehr stark vom verwendeten meteorologischen Datensatz ab. Für diesen kommen verschiedene Datenquellen infrage. Üblicherweise werden für Gebäudesimulationen Testreferenzjahre des Deutschen Wetterdienstes gewählt, die sowohl für die Gegenwart als auch für Zukunftsszenarien vorliegen. Ein weiterer Ansatz ist die Nutzung von meteorologischen Messdaten, die jedoch nicht überall zur Verfügung stehen. Um mikroskalige Effekte zu berücksichtigen, können Stadtklimasimulationen mit horizontaler Auflösung von wenigen Metern durchgeführt werden und als Eingangsgrößen für Gebäudesimulationen dienen. In diesem Artikel wird ein Überblick über die verschiedenen Möglichkeiten des meteorologischen Inputs und den daraus folgenden starken Abweichungen bei der Beurteilung der Hitzebelastung im Gebäude gegeben. Dabei wird aufgezeigt, dass zur Generierung valider meteorologischer Daten für die Evaluierung der Hitzebelastung in Innenräumen noch deutlicher Forschungsbedarf besteht.

An Interdisciplinary Decision Framework for Risk-Based Nuclear Power Plant Emergency Planning and Protective-Action Strategy Selection

Publisher: name: Carnegie Mellon University
Year: 2022
Subjects: subject: 160510 Public Policy

description: Emergency planning is a required component of licensing for nuclear power plants. A rare opportunity to redefine emergency preparedness has been created by the ongoing work at the Nuclear Regulatory Commission to develop the capability to address small modular reactors and other new technologies and to transition to a risk-informed performance-based regulatory structure. This dissertation develops a new framework for emergency preparedness that can address the characteristics of new reactor technologies while also addressing the limitations of current methods. A review of the literature, current regulations, and methods identifies gaps and limitations. Statistically valid methods are defined to enable new analysis of uncertainty and use cases in limited regulatory validated computer codes. A new interdisciplinary framework for emergency planning is developed to reduce the barriers present in current methods, then a risk-based model that integrates protective action and hazard dispersion models is defined. This integrated model considers the risk caused by multiple hazards, including radiological and transportation hazards. The interdisciplinary and integrated structure of the model provides the opportunity for new measures of effectiveness that provide additional insights beyond existing metrics.The integrated model is used to evaluate emergency response at the Peach Bottom Atomic Power Station as a case study. The key findings of this case study provide insight into effects previously not discussed in nuclear power emergency planning studies. The ability to compare protective actions across multiple metrics allows for risk and consequences-based evaluation and provides more information for decision-makers. When combined dose and non-dose risks are considered, many historically common protective action strategies become inadvisable by creating more combined risk than taking no action. Even small amounts of time between initiating a protective action and the release of radiation can potentially result in a substantial reduction of consequences. The behavior of the population has a large impact on consequences but is not sufficiently captured in prior studies.

The model leads to the prediction, that the visibility of the output signal will exhibit increasing variation as the coincidence window is increased, thus providing a testable criteria for its validity. If it can be sustained, this model undermines the claim that Nature has a fundamentally nonlocal feature or that irreal entities are required by quantum theory.

description: The determination of the lower-end of the initial mass function (IMF) provides strong constraints on star formation theories. We report here on a search for isolated planetary-mass objects in the 3 Myr-old star-forming region IC 348. Deep, narrowband CH4off and CH4on images were obtained with CFHT/WIRCam over 0.11 sq.deg. in the central part of IC 348 to identify young T-dwarfs from their 1.6 um methane absorption bands. We report three faint T-dwarf candidates with CH4on-CH4off colours > 0.4 mag. Extinction was estimated for each candidate and lies in the range Av ~ 5-12 mag. Comparisons with T-dwarf spectral models, and colour/colour and colour/magnitude diagrams, reject two of the three candidates because of their extreme z' - J blueness. The one remaining object is not thought to be a foreground field dwarf because of a number density argument and also its strong extinction Av - 12 mag, or thought to be a background field T-dwarf which would be expected to be much fainter. Models and diagrams give this object a preliminary T6 spectral type. With a few Jupiter masses, the young T-dwarf candidate reported here is potentially amongst the youngest, lowest mass objects detected in a star-forming region so far. Its frequency is consistent with the extrapolation of current lognormal IMF estimates down to the planetary mass domain.

description: In mountain environments dimensions of climate change are unclear because of limited availability of meteorological stations. However, there is a necessity to assess the scope of local climate change, as the livelihood and food systems of subsistence-based communities are already getting impacted. To provide more clarity about local climate trends in the Pamir Mountains of Tajikistan, this study integrates measured climate data with community observations in the villages of Savnob and Roshorv. Taking a transdisciplinary approach, both knowledge systems were considered as equally pertinent and mutually informed the research process. Statistical trends of temperature and snow cover were retrieved using downscaled ERA5 temperature data and the snow cover product MOD10A1. Local knowledge was gathered through community workshops and structured interviews and analysed using a consensus index. Results showed, that local communities perceived increasing temperatures in autumn and winter and decreasing amounts of snow and rain. Instrumental data records indicated an increase in summer temperatures and a shortening of the snow season in Savnob. As both knowledge systems entail their own strengths and limitations, an integrative assessment can broaden the understanding of local climate trends by (i) reducing existing uncertainties, (ii) providing new information, and (iii) introducing unforeseen perspectives. The presented study represents a time-efficient and global applicable approach for assessing local dimensions of climate change in data-deficient regions.
Probing the interaction between bacteriophages and of Salmonella enterica
Creators: name: Wong, Catherine Wai Yee
Publisher: name: University of British Columbia

description: Salmonella enterica (S. enterica) is a leading bacterial pathogen for foodborne outbreaks in fresh produce. The industry uses chemical washes or sanitizers to reduce pathogens, but natural foods without chemical intervention have been gaining popularity. This has led to rising interests in using bacteriophages, a virus that targets bacteria. To determine the efficacy of bacteriophages against S. enterica on post-harvest produce, the efficacy of a bacteriophage cocktail against S. enterica strains on Romaine lettuce leaf and cantaloupe flesh was examined for objective 1. Populations of S. enterica were reduced by 1–4 log CFU/cm². However, populations of S. Thompson were not significantly different (P > 0.05) from the controls after day 0. Thre was only one bacteriophage application for objective 1 and this led to determining if repeated bacteriophage applications could further reduce S. enterica populations on pre-harvest produce for objective 2. Bacteriophage cocktails were applied against S. enterica strains daily on germinating alfalfa sprout seeds from day 0–7. The results showed S. Enteritidis to be most susceptible to both cocktails. S. enterica populations on all strains continued to proliferate even with repeated daily bacteriophage applications, but populations were decreased compared to just one bacteriophage application. The population resurgence after repeated applications led to a third objective to determine if there is an optimum bacteriophage MOI and how S. enterica behaves mechanistically after bacteriophage treatment. For objective 3, two bacteriophage cocktails were co-inoculated with S. enterica strains at different MOIs, and the expression of selected genes were examined. MOI 1000 was the most optimal and reduced S. Enteritidis populations to undetectable levels from day 0 – 3. Cas1, mod and hsdS genes were highly upregulated between 2.5 – 5-folds for S. Enteritidis S5-483 and S. Typhimurium S5-536. The results of this study showed that bacteriophages can reduce S. enterica populations and repeated bacteriophage applications can further reduce S. enterica populations on fresh produce. The understanding into the transcriptional response of S. enterica after the bacteriophage treatment gives further insight into how S. enterica can survive bacteriophage treatment and ways to target S. enterica more effectively.

description: The compact binary system in OJ287 is modelled to contain a spinning primary black hole with an accretion disk and a non-spinning secondary black hole. Using Post Newtonian (PN) accurate equations that include 2.5PN accurate non-spinning contributions, the leading order general relativistic and classical spin-orbit terms, the orbit of the binary black hole in OJ287 is calculated and as expected it depends on the spin of the primary black hole. Using the orbital solution, the specific times when the orbit of the secondary crosses the accretion disk of the primary are evaluated such that the record of observed outbursts from 1913 up to 2007 is reproduced. The timings of the outbursts are quite sensitive to the spin value. In order to reproduce all the known outbursts, including a newly discovered one in 1957, the Kerr parameter of the primary has to be $0.28 \pm 0.08$. The quadrupole-moment contributions to the equations of motion allow us to constrain the `no-hair' parameter to be $1.0\:\pm\:0.3$ where 0.3 is the one sigma error. This supports the `black hole no-hair theorem' within the achievable precision. It should be possible to test the present estimate in 2015 when the next outburst is due. The timing of the 2015 outburst is a strong function of the spin: if the spin is 0.36 of the maximal value allowed in general relativity, the outburst begins in early November 2015, while the same event starts in the end of January 2016 if the spin is 0.2

description: Wind ist ein wichtiges und gleichzeitig sehr komplexes Element des urbanen Klimas. Die lokalen Windverhältnisse bilden ein Wechselspiel aus großräumigem Windfeld und den lokalen städtischen Gegebenheiten und können innerhalb eines Stadtgebiets große Unterschiede aufweisen. Verschiedenskalige Windsysteme wie Flurwind, Land-/Seewind, Berg-/Talwind oder Regionalwinde (z. B. Alpines Pumpen) können zur Verbesserung oder Verschlechterung der Luftqualität in Städten beitragen. Stürme und Gewitter haben bei hohen Windgeschwindigkeiten in Städten ein großes Schadenspotenzial. Für vereinfachte Annahmen, beispielsweise einzelne Häuser oder gleichmäßig angeordnete Straßenschluchten, lässt sich das Windfeld gut beschreiben. Diese idealen Verhältnisse entsprechen jedoch den wenigsten Städten und können nur als erste Näherung herangezogen werden. Die städtische Morphologie hat einen erheblichen Einfluss auf das lokale Windfeld. Für viele Anwendungen bedarf es daher spezifischeren Untersuchungen, die vor allem durch die Entwicklung der Stadtklimamodelle in den letzten Jahren immer besser und realistischer wurden.

description: We employ a thermodynamic analysis to determine the phase structure of Eguchi-Hanson solitons, Schwarzschild-AdS/$\mathbb{Z}_k$ black holes and thermal AdS/$\mathbb{Z}_k$. The Euclidean actions are calculated by two equable means: the first uses the Eguchi-Hanson soliton as the thermal background while the second makes use of minimal boundary counterterms in the action necessary to render individual actions finite. The Euclidean actions are then utilised to determine the phase structure in arbitrary odd dimension; it is found that there is a Hawking-Page phase transition and also a phase transition between the black hole and soliton. There is found to be no smooth phase transition governed by an order parameter between AdS/$\mathbb{Z}_k$ and the soliton but nevertheless AdS/$\mathbb{Z}_k$ changes phase by tunneling to the lower energy soliton configuration.

description: The aim of this paper is to investigate the cohomologies for ternary algebras of associative type. We study in particular the cases of partially associative ternary algebras and weak totally associative ternary algebras. Also, we consider the Takhtajan's construction, which was used to construct a cohomology of ternary Nambu-Lie algebras using Chevalley-Eilenberg cohomology of Lie algebras, and discuss it in the case of ternary algebras of associative type. One of the main results of this paper states that a deformation cohomology does not exist for partially associative ternary algebras which implies that their operad is not a Koszul operad.

description: We study the statistical nature of primordial fluctuations from an anisotropic inflation which is realized by a vector field coupled to an inflaton. We find a suitable gauge, which we call the canonical gauge, for anisotropic inflation by generalizing the flat slicing gauge in conventional isotropic inflation. Using the canonical gauge, we reveal the structure of the couplings between curvature perturbations, vector waves, and gravitational waves. We identify two sources of anisotropy, i.e. the anisotropy due to the anisotropic expansion of the universe and that due to the anisotropic couplings among variables. It turns out that the latter effect is dominant. Since the coupling between the curvature perturbations and vector waves is the strongest one, the statistical anisotropy in the curvature perturbations is larger than that in gravitational waves. We find the cross correlation between the curvature perturbations and gravitational waves which never occurs in conventional inflation. We also find the linear polarization of gravitational waves. Finally, we discuss cosmological implication of our results.

Tackling Challenges Related to Thick Electrodes in Platinum Group Metal Free Polymer Electrolyte Fuel Cells

description: Platinum group metal-free catalysts (PGM-free) are a promising option to counter the high cost of platinum in proton exchange membrane fuel cells (PEMFCs). The recent improvements to PGM-free catalyst activity has allowed us to ad- dress the two primary challenges for PGM-free catalyst PEMFC marketability: durability and resistance. To counter the lower volumetric activity of the PGM-free catalyst, more is used resulting in a thicker cathode catalyst layer (CCL) and increased resistance. To mitigate this effect, we lessened chemical species resistance by exploring different PGM-free catalyst and ink compositions via electrochemical experiments. For example, optimizing particle size and ionomer content enabled sufficient species transport to achieve state of the art PGM-free MEA performance. Several novel electrodes were designed for water management and oxygen transport improvement, the most effective of which was the non-planar CCL. This work was enhanced and expedited by the use and validation of a two-phase non-isothermal PEMFC model. The model was also used to elucidate relative contributions of different oxygen transport resistances and show that oxygen limited transport is actually caused by fast proton transportdue to increasing temperature instead of flooding. Parametric modeling studies offered insights to further optimizations, such as optimizing thickness to balance oxygen transport and activity, which in turn was realized experimentally.
Zeros of the hypergeometric polynomial F(-n,b;c;z)

description: Our interest lies in describing the zero behaviour of Gauss hypergeometric polynomials $F(-n,b; c; z)$ where $b$ and $c$ are arbitrary parameters. In general, this problem has not been solved and even when $b$ and $c$ are both real, the only cases that have been fully analyzed impose additional restrictions on $b$ and $c$. We review recent results that have been proved for the zeros of several classes of hypergeometric polynomials $F(-n,b; c; z)$ where $b$ and $c$ are real. We show that the number of real zeros of $F(-n,b; c; z)$ for arbitrary real values of the parameters $b$ and $c$, as well as the intervals in which these zeros (if any) lie, can be deduced from corresponding results for Jacobi polynomials.

description: The exact mean time between encounters of a given particle in a system consisting of many particles undergoing random walks in discrete time is calculated, on both regular and complex networks. Analytical results are obtained both for independent walkers, where any number of walkers can occupy the same site, and for walkers with an exclusion interaction, when no site can contain more than one walker. These analytical results are then compared with numerical simulations, showing very good agreement.

description: Critical current density was studied in single crystals of Ba(Fe$_{1-x}$Co$_x$)$_2$As$_2$ for the values of $x$ spanning the entire doping phase diagram. A noticeable enhancement was found for slightly underdoped crystals with the peak at $x = 0.058$. Using a combination of polarized-light imaging, x-ray diffraction and magnetic measurements we associate this behavior with the intrinsic pinning on structural domains in the orthorhombic phase. Domain walls extend throughout the sample thickness in the direction of vortices and act as extended pinning centers. With the increasing $x$ domain structure becomes more intertwined and fine due to a decrease of the orthorhombic distortion. This results in the energy landscape with maze-like spatial modulations favorable for pinning. This finding shows that iron-based pnictide superconductors, characterized by high values of the transition temperature, high upper critical fields, and low anisotropy may intrinsically have relatively high critical current densities.

The effects of arterial oxygen and carbon dioxide tension on cerebral vascular physiology in hypoxic ischemic brain injury after cardiac arrest
Creators: name: Schoenthal, Tison David
Publisher: name: University of British Columbia
Year: 2023

description: Hypoxic ischemic brain injury (HIBI) is the resultant cerebral injury acquired after cardiac arrest stemming from cerebral ischemia during circulatory arrest and reperfusion following return of spontaneous circulation. Regrettably, HIBI outcomes remain poor, with survivors commonly experiencing neurological disabilities and neuropsychiatric sequelae. A cornerstone of HIBI management focusses on optimizing cerebral oxygen delivery and utilization. Central to this objective, the manipulation of arterial blood gases has come under scrutiny as a potential therapeutic approach, specifically the implementation of normobaric hyperoxia and mild hypercapnia. In study 1, normobaric hyperoxia was administered in post-cardiac arrest HIBI patients for 6 hours, targeting an arterial oxygen tension (PaO₂) of 200–300mmHg. Patients were monitored with jugular venous bulb oximetry, near infrared spectrometry and hemodynamic bedside monitoring in the ICU, with arterial and jugular venous blub blood samples taken at baseline, 2-, 4-, and the 6- hour mark, and following the resumption of normoxemia (PaO₂ 80–120mmHg) with additional blood samples taken at the 12- and 24-hour marks. The jugular venous oxygen saturation and regional saturation of oxygen did not increase during exposure to normobaric hyperoxia. Neurofilament light, a blood-based biomarker reflecting axonal injury, was significantly elevated at the 6-hour mark. In study 2, mild hypercapnia was administered for 2 hours in post-cardiac arrest HIBI patients who were monitored with transcranial Doppler ultrasound (TCD), jugular venous bulb oximetry and hemodynamic bedside monitoring. Baseline serum and plasma samples were taken from the in situ arterial and jugular venous bulb catheters, and then repeated at the 1- and 2- hour marks. TCD was also conducted in 15 healthy humans who were exposed to mild hypercapnia for control comparisons. Arterial CO₂ levels significantly increased during the study; however, no differences were seen in the jugular venous bulb oxygen saturation or cerebral oxygen extraction fraction. The cerebral arterio-venous difference of ubiquitin carboxyl hydrolase L1, a biomarker of neuron cell body injury, decreased at the 1-hour mark. HIBI patients also demonstrated decreased cerebrovascular reactivity and conductance compared to healthy humans when exposed to mild hypercapnia.

description: The distribution of entangled states between distant parties in an optical network is crucial for the successful implementation of various quantum communication protocols such as quantum cryptography, teleportation and dense coding [1-3]. However, owing to the unavoidable loss in any real optical channel, the distribution of loss-intolerant entangled states is inevitably inflicted by decoherence, which causes a degradation of the transmitted entanglement. To combat the decoherence, entanglement distillation, which is the process of extracting a small set of highly entangled states from a large set of less entangled states, can be used [4-14]. Here we report on the mesoscopic distillation of deterministically prepared entangled light pulses that have undergone non-Gaussian noise. The entangled light pulses [15-17] are sent through a lossy channel, where the transmission is varying in time similarly to light propagation in the atmosphere. By employing linear optical components and global classical communication, the entanglement is probabilistically increased.

description: We present a semiclassical theory of spin-diffusion in a ferromagnetic metal subject to a temperature gradient. Spin-flip scattering can generate pure thermal spin currents by short-circuiting spin channels while suppressing spin accumulations. A thermally induced spin density is locally generated when the energy dependence of the density of states is spin polarized.
