description: There is no denying that spreadsheets have become critical for all operational processes including financial reporting, budgeting, forecasting, and analysis. Microsoft Excel has essentially become a scratch pad and a data browser that can quickly be put to use for information gathering and decision-making. However, there is little control in how data comes into Excel, and how it gets updated. The information supply chain feeding into Excel remains ad hoc and without any centralized IT control. This paper discusses some of the pitfalls of the data collection and maintenance process in Excel. It then suggests service-oriented architecture (SOA) based information gathering and control techniques to ameliorate the pitfalls of this scratch pad while improving the integrity of data, boosting the productivity of the business users, and building controls to satisfy the requirements of Section 404 of the Sarbanes-Oxley Act.

The salience of gender in the assessment of job candidates
Creators: name: Sigerson, Kirsten
Publisher: name: University of British Columbia
Year: 2008

description: Status Characteristics theory predicts that gender will become salient and activate different performance expectations for men and women in situations where either (1) performers are in a mixed-sex group or (2) gender is explicitly linked to the task at hand, or (3) both. This prediction has been clearly supported by previous studies in this field. The present experiment explores whether gender is so fundamental in person perception that it will still be a basis for judgement in the absence of the foregoing conditions. Subjects made competence and suitability assessments, as well as hiring and salary recommendations, about student applicants vying for engineering jobs. Each assessor, either male or female, was given two files (order varied) to review in succession, one from an "average" candidate, the other from an "outstanding" one. In each case the applicant was either male or female. As predicted, results indicated a main effect due to level of performance on all four dependent measures, whereby the superior candidate was recommended for the position more often than the mediocre one, given a higher starting salary, and seen as more competent and more suitable for the job. Although there were no sex of candidate effects with respect to competence and suitability rankings, nor with hiring recommendations, effects of candidate's sex still persisted regarding salary. On this variable, results demonstrated a significant interaction whereby subjects favoured the male candidate at the average level, but the female candidate at the superior one. Further analysis on this factor revealed that a sex difference existed as well; that is, in evaluating average performers, men were biased in favour of male applicants, while in the assessment of outstanding performers, it was women who gave preferential treatment to members of their own sex. Implications of these findings are discussed in the context of the scope conditions of status characteristics theory.
A new pattern in a shift of light : a study of Rudyard Kipling as a 20th century writer
Creators: name: Snider, Philip R.
Publisher: name: University of British Columbia
Year: 2008

description: For most of the hundred years or so that Rudyard Kipling's works have been available in print, they have suffered under a certain amount of critical disapprobation. In many cases such criticism has been politically motivated, particularly among writers and critics of the Modernist movement. This is a paradox because, in his best works, Kipling shows a strong affinity for Modernist issues as demonstrated in his concern for the themes of isolation and abandonment, and the quest for healing, and in his use of indeterminate narrative structure. The dichotomies in his life and work have also resulted in profound misunderstandings of his writings. Nevertheless, his subjects and methods combine to establish Rudyard Kipling as a powerful and significant 20th century writer.

description: We demonstrate a 13.3 MHz repetition rate, broadband THz source with milliwatt-average power, obtained by collinear optical rectification of a high-power Yb-doped thin-disk laser in the organic crystal BNA (N-benzyl-2-methyl-4-nitroaniline). Our source reaches a maximum THz average power of 0.95 mW with an optical-to-THz efficiency of 4e-4 and a spectral bandwidth spanning up to 6 THz at -50 dB, driven by 2.4 W average power (after an optical chopper with duty cycle of 10%), 85 fs-pulses. This high average power excitation was possible without damaging the crystal by using a diamond-heatsinked crystal with significantly improved thermal properties. To the best of our knowledge, this result represents the highest THz average power reported so far using the commercially available organic crystal BNA, showing the potential of these crystals for high average power, high repetition rate femtosecond excitation. The combination of high power, high dynamic range, high repetition rate and broadband spectrum makes the demonstrated THz source highly attractive to improve various time-domain spectroscopy applications. Furthermore, we present a first exploration of the thermal behavior of BNA in this excitation regime, showing that thermal effects are the main limitation in average power scaling in these crystals.

description: We consider point particles in a table made of two circular cavities connected by two rectangular channels, forming a closed loop under periodic boundary conditions. In the first channel, a bounce--back mechanism acts when the number of particles flowing in one direction exceeds a given threshold $T$. In that case, the particles invert their horizontal velocity, as if colliding with vertical walls. The second channel is divided in two halves parallel to the first, but located in the opposite sides of the cavities. In the second channel, motion is free. We show that, suitably tuning the sizes of cavities, of the channels and of $T$, non--equilibrium phase transitions take place in the $N\rightarrow \infty$ limit. This induces a stationary current in the circuit, thus modeling a kind of battery, although our model is deterministic, conservative, and time reversal invariant.

description: Experimental realization of a universal set of quantum logic gates with high-fidelity is critical to quantum information processing, which is always challenging by inevitable interaction between the quantum system and environment. Geometric quantum computation is noise immune, and thus offers a robust way to enhance the control fidelity. Here, we experimentally implement the recently proposed extensible nonadiabatic holonomic quantum computation with solid spins in diamond at room-temperature, which maintains both flexibility and resilience against decoherence and system control errors. Compared with previous geometric method, the fidelities of a universal set of holonomic single-qubit and two-qubit quantum logic gates are improved in experiment. Therefore, this work makes an important step towards fault-tolerant scalable geometric quantum computation in realistic systems.

description: The compound BaCuSi2O6 is a quantum magnet with antiferromagnetic dimers of S = 1/2 moments on a quasi-2D square lattice. We have investigated its spin dynamics by inelastic neutron scattering experiments on single crystals with an energy resolution considerably higher than in an earlier study. We observe multiple magnon modes, indicating clearly the presence of magnetically inequivalent dimer sites. This more complex spin Hamiltonian leads to a distinct form of magnon Bose-Einstein condensate (BEC) phase with a spatially modulated condensate amplitude.

description: The propagation mechanisms of plasma streamers have been observed and investigated in a surface dielectric barrier discharge (SDBD) using 2D particle in cell simulations. The investigations are carried out under a simulated air mixture, 80\% N$_2$ and 20\% O$_2$, at atmospheric pressure, 100$\,$kPa, under both DC conditions and a pulsed DC waveform that represent AC conditions. The simulated geometry is a simplification of the symmetric and fully exposed SDBD resulting in the simultaneous ignition of both positive and negative streamers on either side of the Al$_2$O$_3$ dielectric barrier. In order to determine the interactivity of the two streamers, the propagation behavior for the positive and negative streamers are investigated both independently and simultaneously under identical constant voltage conditions. An additional focus is implored under a fast sub nanosecond rise time square voltage pulse alternating between positive and negative voltage conditions, thus providing insight into the dynamics of the streamers under alternating polarity switches. It is shown that the simultaneous ignition of both streamers, as well as using the pulsed DC conditions, provides both an enhanced discharge and an increased surface coverage. It is also shown that additional streamer branching may occur in a cross section that is difficult to experimentally observe. The enhanced discharge and surface coverage may be beneficial to many applications such as, but are not limited to: air purification, volatile organic compound removal, and plasma enhanced catalysis.

description: Cell division cycle 42 (CDC42) regulates the development of colorectal cancer (CRC) by modulating cancer malignant behaviors and facilitating immune escape. Hence, this study aimed to explore the correlation of blood CDC42 with treatment response and survival benefit to programmed cell death-1 (PD-1) inhibitor-based regimens in inoperable metastatic CRC (mCRC) patients. Fifty-seven inoperable mCRC patients who received PD-1 inhibitor-based regimens were recruited. The CDC42 in peripheral blood mononuclear cell (PBMC) was detected using RT-qPCR in inoperable mCRC patients at baseline and after 2-cycle treatment. Besides, PBMC CDC42 in 20 healthy controls (HCs) was also detected. CDC42 was higher in inoperable mCRC patients compared to HCs (p < 0.001). Elevated CDC42 was related to a higher performance status score (p = 0.034), multiple metastatic sites (p = 0.028), and the presence of liver metastasis (p = 0.035) in inoperable mCRC patients. During the 2-cycle treatment, CDC42 was reduced (p < 0.001). Higher CDC42 at baseline (p = 0.016) and after 2-cycle treatment (p = 0.002) were both linked with decreased objective response rate. CDC42 high at baseline was related to shorter progression-free survival (PFS) (p = 0.015) and overall survival (OS) (p = 0.050). Moreover, CDC42 high after 2-cycle treatment was also related to unfavorable PFS (p < 0.001) and OS (p = 0.001). After adjustment using multivariate Cox’s analyses, CDC42 high after 2-cycle treatment independently related to shorter PFS (hazard ratio (HR): 4.129, p < 0.001), and CDC42 reduction ≤230% also independently correlated with shorter OS (HR: 4.038, p < 0.001). The longitudinal change of blood CDC42 during PD-1 inhibitor-based regimen estimates treatment response and survival in inoperable mCRC patients.

description: The $q$-Onsager algebra $O_q$ has a presentation involving two generators $W_0$, $W_1$ and two relations, called the $q$-Dolan/Grady relations. The alternating central extension $\mathcal O_q$ has a presentation involving the alternating generators $\lbrace \mathcal W_{-k}\rbrace_{k=0}^\infty$, $\lbrace \mathcal W_{k+1}\rbrace_{k=0}^\infty$, $ \lbrace \mathcal G_{k+1}\rbrace_{k=0}^\infty$, $\lbrace \mathcal {\tilde G}_{k+1}\rbrace_{k=0}^\infty$ and a large number of relations. Let $\langle \mathcal W_0, \mathcal W_1 \rangle$ denote the subalgebra of $\mathcal O_q$ generated by $\mathcal W_0$, $\mathcal W_1$. It is known that there exists an algebra isomorphism $O_q \to \langle \mathcal W_0, \mathcal W_1 \rangle$ that sends $W_0\mapsto \mathcal W_0$ and $W_1 \mapsto \mathcal W_1$. It is known that the center $\mathcal Z$ of $\mathcal O_q$ is isomorphic to a polynomial algebra in countably many variables. It is known that the multiplication map $\langle \mathcal W_0, \mathcal W_1 \rangle \otimes \mathcal Z \to \mathcal O_q$, $ w \otimes z \mapsto wz$ is an isomorphism of algebras. We call this isomorphism the standard tensor product factorization of $\mathcal O_q$. In the study of $\mathcal O_q$ there are two natural points of view: we can start with the alternating generators, or we can start with the standard tensor product factorization. It is not obvious how these two points of view are related. The goal of the paper is to describe this relationship. We give seven main results; the principal one is an attractive factorization of the generating function for some algebraically independent elements that generate $\mathcal Z$.

description: Flavonoids are important secondary metabolites that exist in many medicinal plants. Flavonoid glycosyltransferases can transfer sugar moieties to their parent rings, producing various flavonoid glycosides with significant pharmacological activities. Here, we report the molecular cloning of the O-glycosyltransferase TwUGT2 from Tripterygium wilfordii and its catalytic activity was explored by heterologous expression in E. coli. The results showed that TwUGT2 has specific glycosyltransferase activity towards C-3 and 7 hydroxyl groups of flavonoids, thereby converting quercetin and pinocembrin into isoquercitrin and pinocembrin 7-O-beta-D-glucoside, respectively. The identification of TwUGT2 will provide a useful molecular tool for synthetic biology and contribute to drug discovery.

description: We investigate the topology of the completed 2dF Galaxy Redshift Survey, drawing two flux-limited samples of the local Universe from the 2dFGRS catalogue, which contains over 220,000 galaxies at a median redshift of z = 0.11. The samples are cut at z = 0.2 and corrected for selection effects. We then use the three-dimensional genus statistic to probe the connectedness of the galaxy distribution on scales ranging from 8 to 20 Mpc, and compare these measurements with the analytical result for a Gaussian random density field, a generic prediction of inflationary models. We demonstrate consistency with inflation on the range of scales considered. We then introduce a parameterisation of the analytic genus curve formula that is sensitive to asymmetries in genus number as a function of density and use it to demonstrate that such phenomena are ruled out with 95% confidence between 8 and 16 Mpc.

description: LOFAR is the only radio telescope that is presently capable of high-sensitivity, high-resolution (<1 mJy/b and <15") observations at ultra-low frequencies (<100 MHz). To utilise these capabilities, the LOFAR Surveys Key Science Project is undertaking a large survey to cover the entire northern sky with Low Band Antenna (LBA) observations. The LOFAR LBA Sky Survey (LoLSS) aims to cover the entire northern sky with 3170 pointings in the frequency range 42-66 MHz, at a resolution of 15 arcsec and at a sensitivity of 1 mJy/b. Here we outline the survey strategy, the observational status, the current calibration techniques, and briefly describe several scientific motivations. We also describe the preliminary public data release. The preliminary images were produced using a fully automated pipeline that aims to correct all direction-independent effects in the data. Whilst the direction-dependent effects, such as those from the ionosphere, are not yet corrected, the images presented in this work are still 10 times more sensitive than previous surveys available at these low frequencies. The preliminary data release covers 740 sqdeg around the HETDEX spring field region at a resolution of 47" with a median noise level of 5 mJy/b. The images and the catalogue with 25,247 sources are publicly released. We demonstrate that the system is capable of reaching an rms noise of 1 mJy/b and the resolution of 15" once direction-dependent effects are corrected for. LoLSS will provide the ultra-low-frequency information for hundreds of thousands of radio sources, providing critical spectral information and producing a unique dataset that can be used for a wide range of science topics such as: the search for high redshift galaxies and quasars, the study of the magnetosphere of exoplanets, and the detection of the oldest populations of cosmic-rays in galaxies, clusters of galaxies, and from AGN activity.

description: In the present thesis we study the method of electrical prospecting and in particular the application of optimized measurement schemes for cross-borehole electrode arrangement. The optimum protocols we used were calculated using the Jacobian matrix method. For all tested protocols the forward modeling calculations were performed for several subsurface resistivity models and different cross-borehole distances. The produced synthetic data were subjected to inversion for both static and time-lapse geoelectrical models. The qualitative and quantitative comparison of the inversion results with respect to the original models used to produce the synthetic data made it possible to draw conclusions about the relative performance of protocols. In particular, the comprehensive protocol gave the best results while good quality results were also obtained using the optimum protocol but with significant less measurement compared to the comprehensive protocol.

description: Considering a bidirectionally pumped ring microresonator, we provide a concise derivation of the model equations allowing us to eliminate the repetition rate terms and reduce the nonlinear interaction between the counter-propagating waves to the power-dependent shifts of the resonance frequencies. We present the simulation results of the soliton control by swiping the frequency of the counter-propagating wave in the forward and backward directions and with the soliton-blockade effect either present or not. We highlight the non-reciprocity of the forward and backward scans. Furthermore, we report the soliton crystals and breathers existing in the vicinity of the blockade interval.

description: Ο τίτλος ἀξιολογώτατος ήταν ένας επίσημος τίτλος, ο οποίος πιθανόν απονεμόταν από την πόλη και ήταν σε χρήση από τις αρχές του 2ου, μέχρι και τον 4ο αιώνα μ.Χ.. Οι φορείς του ήταν διακεκριμένα πρόσωπα, τα οποία είχαν διανύσει μια λαμπρή πολιτική σταδιοδρομία και αποτελούσαν την αφρόκρεμα των Κοινών και των επαρχιών που ανήκαν. Από τα συμφραζόμενα των επιγραφών, φαίνεται πως το ἀξιολογώτατος ήταν δείκτης της εξαιρετικής θητείας κατά τη διάρκεια μιας ἀρχής ή την ανάληψη κάποιας λειτουργίας ενός αξιωματούχου, οι πράξεις του οποίου ξεπερνούσαν τις προσδοκίες της πόλεώς του. Γίνεται σαφές πως αποτελούσε έναν σημαντικό τίτλο διάκρισης μέσα στην ίδια την elite. Οι φορείς του προσπάθησαν να τον διασφαλίσουν για τα μέλη των οικογενειών τους και δημιουργώντας με αυτό τον τρόπο μια οικογενειακή παράδοση αξιέπαινων πράξεων, οι ἀξιολογώτατοι αντικατοπτρίζουν μία τάση της εποχής τους. Αφενός τη διεκδίκηση μιας ηγετικής θέσης μέσα στις πόλεις και τα κοινά και αφετέρου τη διασφάλιση της θέσης αυτής και για τα επόμενα μέλη της οικογένειάς τους. Ο τίτλος αποτελεί άλλη μία ένδειξη της άτυπης αυτής κληρονομικής αριστοκρατίας που δημιουργείται, όσο το πολιτικό σύστημα των ελληνικών πόλεων “ολιγαρχικοποιείται” όλο και περισσότερο μέσα στην Αυτοκρατορική Περίοδο.
description: Ἀξιολογώτατος was an official title, probably awarded by the city’s institutions. It was first introduced in the beginning of the 2nd cent. A.D. and remained in use until the end of the 4th. Those who held the title were prominent citizens in their cities, Κοινά and provinces and achieved a remarkable political career. Studying the inscriptions, it becomes clear that the title was used to indicate an exceptional act during an office. The title holders exceeded the expectations that the city had for them, probably by spending huge sums from their personal wealth for the community’s benefit. Ἀξιολογώτατος was used to distinct prominent people, not from the rest body of citizens, but within the elite itself. Those who held the title tried to secure it for their descendants, in order to create a family tradition of exceptional and noteworthy acts. This title reflects in a very characteristic way the need of Greek aristocracy to claim a leading role in the city and province administration on the one hand and securing and perpetuating this role for its descendants on the other, during the Imperial Period.

For this purpose, the synthesis of Mg(BH$_4$)$_2$ from MgB$_2$ in a pressurized hydrogen atmosphere was chosen as a model reaction. MgB$_2$ was milled under a broad set of milling parameters (i.e. milling times and rotation regimes) and the obtained product thoroughly characterized. By proving the partial formation of Mg(BH$_4$)$_2$, the results of this investigation indicate that the energy transferred to the powder bed by the powder particles colliding with the chamber wall during milling is not negligible, in particular when the milling process is protracted for a long period.

description: Η παρούσα μεταπτυχιακή εργασία διερευνά τη σχέση της παιδαγωγικής του Paulo Freire και του θεάτρου του Augusto Boal σε όλη τη διάρκεια της ζωής τους, με σκοπό τη συνολική προσέγγιση του έργου τους και ταυτόχρονο συσχετισμό τους. Επιχειρείται να απαντηθεί το κεντρικό ερευνητικό ερώτημα: Ποια είναι η επιρροή της παιδαγωγικής του Freire στο θέατρο του Boal. Πιο συγκεκριμένα, εξετάζεται ποια είναι η επιρροή του έργου του Freire στο έργο του Boal ως προς τους σκοπούς και το περιεχόμενό του καθώς και την ιδεολογία που το διαπνέει. Για την απάντηση των παραπάνω ερωτημάτων γίνεται μια περιοδολόγηση του έργου των δύο Βραζιλιάνων με ταυτόχρονη μελέτη του ιστορικού πλαισίου της κάθε περιόδου ώστε να αναδειχθούν ξεκάθαρα οι επιρροές που δέχεται ο Augusto Boal από τον Paulo Freire.
description: This thesis researches the relation between Paulo Freire’s pedagogy and Augusto Boal’s theatre throughout their lives aiming to an overall approach of their work and simultaneously a correlation between them. It attempts to answer a basic research question: What is the influence of Freire’s pedagogy in Boal’s theatre. Specifically, what is the influence of Freire’s work in Boal’s work regarding to the purpose, the content and the ideology of their work. In addition, the work of the two Brazilians is examined via a periodization which includes the study of the historical content of each period in order for the influences of Freire’s pedagogy on Boal’s theatre to be clearly identified.

description: Σκοπός της διατριβής ήταν η δικαιολόγηση της πολιτικής ανυπακοής εντός ενός δημοκρατικού πλαισίου διακυβέρνησης. Προκειμένου να αποδειχθεί ότι ορισμένες φορές η παράβαση ενός δημοκρατικού νόμου ενέχει ηθική αξία, εκκινήσαμε από την δικαιολόγηση της πολιτικής υπακοής. Αφού αξιολογήθηκαν τα επικρατέστερα επιχειρήματα - ήτοι της Ευγνωμοσύνης, της Ακριβοδικίας και της Συγκατάθεσης - που αποσκοπούσαν να θεμελιώσουν μία εκ πρώτης όψεως υποχρέωση υπακοής στο δίκαιο, καταλήξαμε στην ανάπτυξη ενός εναλλακτικού επιχειρήματος. Το τελευταίο θεμελιώνει τη διαμειβόμενη υποχρέωση υπακοής στο νόμο στη συμμετοχή του πολίτη σε δύο διαφορετικές μεν, ουσιωδώς συνυφασμένες δε διαδικασίες, τη διαδικασία διαμόρφωσης των αποφάσεων, δηλαδή, το δημόσιο πολιτικό διάλογο και τη διαδικασία εκλογής των αντιπροσώπων. Καταλήξαμε στον παρακάτω ισχυρισμό: η διαμαρτυρία για ένα δημοκρατικό νόμο μέσω της τακτικής της πολιτικής ανυπακοής δικαιολογείται ηθικά, μονάχα όταν κάποια εκ των ανωτέρω δύο διαδικασιών ή και οι δύο μαζί, δε λειτουργούν ορθώς.
description: The aim of the present thesis was to prove that sometimes disobeying the laws of a democratic state is morally justified. In order to lay out a clear and dynamic case for civil disobedience we evaluated the dominant arguments that derive the moral obligation of obedience to law by basing it on the duty of Gratitude, either on the obligation of Fair Play or on the voluntary granting of one's Consent. Then we presented an alternative argument which derives the obligation of obedience to democratic rule of law by basing it on the citizen's participation in the decision-making process. Participants are equal in two procedures, which are central to decision-making, those are the right to participate in the representatives' election and the right to equally participate in the deliberation process. On our way to affirm the case of the justification of civil disobedience to a democratic law, we concluded that whenever the participation in the decision-making is not free from distortions of unequal political power it is morally justified of a citizen to use the political practice of civil dicobedience. Civil disobedience emerges, then, as a means of restoring the democratic deficit rather than a way of forcing one's will on others and undermine democracy.
Strengthened Bell inequalities for orthogonal spin directions

description: We strengthen the bound on the correlations of two spin-1/2 particles (qubits) in separable (non-entangled) states for locally orthogonal spin directions by much tighter bounds than the well-known Bell inequality. This provides a sharper criterion for the experimental distinction between entangled and separable states, and even one which is a necessary and sufficient condition for separability. However, these improved bounds do not apply to local hidden-variable theories, and hence they provide a criterion to test the correlations allowed by local hidden-variable theories against those allowed by separable quantum states. Furthermore, these bounds are stronger than some recent alternative experimentally accessible entanglement criteria. We also address the issue of finding a finite subset of these inequalities that would already form a necessary and sufficient condition for non-entanglement. For mixed state we have not been able to resolve this, but for pure states a set of six inequalities using only three sets of orthogonal observables is shown to be already necessary and sufficient for separability.

Coming out of hibernation : the Canadian public trust doctrine
Creators: name: Smallwood, Kate Penelope
Publisher: name: University of British Columbia
Year: 2008

description: This thesis appears to be the first academic recognition of the public trust doctrine at Canadian common law. Surprisingly, despite the explosion of the doctrine in the United States, there has been little consideration of the doctrine by Canadian courts and only one Canadian article on the subject. To date, Canadian interest in the doctrine has been primarily statutory. In essence, the public trust doctrine means that despite its ownership of natural resources, the government holds certain resources, such as navigable waters, on trust or in a fiduciary capacity for the public. The origins of the doctrine are somewhat vague, but can be traced back to Roman law and the English public rights of navigation and fishing. A review of these public rights reveals that at both law and economics, certain resources are "special" and inherently public in nature. A long and dusty trail through Canadian law reports reveals that Canadian courts have recognized a public trust with respect to navigation and fishing as well as highways. Although the public trust concerning navigation and fishing has lain dormant since the late nineteenth century, the distinctive features of the public rights of navigation and fishing which led both American and Canadian courts to declare a public trust, have been mirrored in Canadian law. Coupled with the initial Canadian recognition of the public trust, the foundations therefore exist for a modern common law revival of the public trust doctrine in Canada. The likely consequences of recognition of the public trust at Canadian common law are : (1) the recognition of a substantive right, and therefore legal standing, in members of the public to vindicate public trust interests; (2) the imposition of an affirmative fiduciary obligation on government with respect to trust resources; (3) the imposition of an administrative process on government with respect to supervision and disposition of public trust resources; (4) restrictions on alienation of trust resources, in particular the restriction that legislation is required to modify or extinguish public trust resources and, (5) in an environmental context, recognition of the importance of the natural environment and the special and inter-related nature of trust resources.

description: We experimentally demonstrate topological slow light waveguides in valley photonic crystals (VPhCs). We employed a bearded interface formed between two topologically-distinct VPhCs patterned in an air-bridged silicon slab. The interface supports both topological and non-topological slow light modes below the light line. By means of optical microscopy, we observed light propagation in the topological mode in the slow light regime with a group index $n_{\rm g}$ over $30$. Furthermore, we confirmed light transmission via the slow light mode even under the presence of sharp waveguide bends. In comparison between the topological and non-topological modes, we found that the topological mode exhibits much more efficient waveguiding than the trivial one, elucidating topological protection in the slow light regime. This work paves the way for exploring topological slow-light devices compatible with existing photonics technologies.

description: Στην παρούσα εργασία μελετήθηκε η επίδραση του πράσου που χρησιμοποιήθηκε ως πρώτη ύλη (κατεψυγμένο, νωπό, ή απουσία από το τελικό προϊόν) για την παραγωγή παραδοσιακών χωριάτικων λουκάνικων καθώς και της διατήρησης των λουκάνικων στον αέρα, αιθυλένιο ή 1-μεθυλο-κυκλοπροπένιο (1-MCP) κατά τo πρώτο χρονικό διάστημα της συντήρησής τους, στην έκλυση CO2, και C2H4, τα μικροβιολογικά και τα φυσικοχημικά τους χαρακτηριστικά κατά την διάρκεια της διατήρησής τους. Τα λουκάνικα με κατεψυγμένο πράσο παρουσίασαν χαμηλότερες τιμές pH και υψηλότερες τιμές τιτλοδοτούμενης οξύτητας, έκλυσης CO2, και του πληθυσμού των γαλακτικών βακτηρίων, συγκριτικά με τα λουκάνικα με νωπό πράσο, πιθανώς λόγω της πιο άμεσης διαθεσιμότητας των θρεπτικών συστατικών στους μικροοργανισμούς αυτούς. Τα λουκάνικα με κατεψυγμένο πράσο παρουσίασαν καθυστέρηση στην μείωση της φωτεινότητας και στην αύξηση της ερυθρότητας η οποία συσχετίσθηκε με χαμηλότερες τιμές των μικρόκοκκων-σταφυλόκοκκων. Επιπλέον, τα λουκάνικα με κατεψυγμένο πράσο παρουσίασαν και υψηλότερη έκλυση CO2 και C2H4 σε σχέση με τα λουκάνικα με νωπό πράσο ή με απουσία πράσου που αποτελεί ένδειξη έντονης δραστηριότητας των μικροοργανισμών. Επίσης, δεν παρατηρήθηκε μικρότερη έκλυση C2H4, στα λουκάνικα που εκτέθηκαν στο 1-MCP. Η αποδεδειγμένη έκλυση C2H4 από τα λουκάνικα με κατεψυγμένο ή χωρίς πράσο αποτελεί ένδειξη ότι το C2H4 αποτελεί τελικό προϊόν της αποικοδόμησης των υποστρωμάτων από τους μικροοργανισμούς.
description: The present work investigates the effect of leek that was used as a raw material (frozen, fresh, or absence from the final product) for the production of Greek traditional sausages (GTS) as well as of maintaining them in the air, ethylene or 1- methylocyclopropene (1-MCP) during the first period of their maintenance in production of CO2 and C2H4, the microbiological characteristics and the physicochemical characteristics during their storage. Sausages manufactured with frozen leek had lower pH values and higher values of TA, CO2 production and LAB population compared with sausages with fresh leek, probably because of the direct distribution of essential nutrients for these microorganisms. Sausages containing frozen leek had delay in reduction of lightness values and in increase in redness values, which is associated with lower MS population values. Furthermore, sausages with frozen leek had higher CO2 and C2H4 production compared with sausages manufactured with fresh leek or without leek at all that indicates intense activity of microorganisms. In addition, sausages treated with 1-MCP had not lower C2H4 production. The proven C2H4 production of GTS manufactured with frozen leek is an indication that C2H4 is the end product of substrates degradation by microorganisms.

description: The crystal structure and numerous normal and superconducting state properties of layered tetragonal (P4/nmm) LaFeAsO, with F-doping of 11 %, are reported. Resistivity measurements give an onset transition temperature Tc = 28.2 K, and low field magnetic susceptibility data indicate bulk superconductivity. In applied magnetic field, analysis of the resistive transition results in a critical field Hc2 = 30 T and a coherence length 35 A. An upper limit for the electron carrier concentration of 1 x 10^21 cm-3 is inferred from Hall data just above Tc. Strong electron-electron correlations are suggested from temperature-dependent resistivity, Seebeck coefficient, and thermal conductivity data. Anomalies near Tc are observed in both Seebeck coefficient and thermal conductivity data.

description: DNS over TLS (DoT) and DNS over HTTPS (DoH) promise to improve privacy and security of DNS by encrypting DNS messages, especially when messages are padded to a uniform size. Firstly, to demonstrate the limitations of recommended padding approaches, we present Segram, a novel app fingerprinting attack that allows adversaries to infer which mobile apps are executed on a device. Secondly, we record traffic traces of 118 Android apps using 10 different DoT/DoH resolvers to study the effectiveness of Segram under different conditions. According to our results, Segram identifies apps with accuracies of up to 72% with padding in a controlled closed world setting. The effectiveness of Segram is comparable with state-of-the-art techniques but Segram requires less computational effort. We release our datasets and code. Thirdly, we study the prevalence of padding among privacy-focused DoT/DoH resolvers, finding that up to 81% of our sample fail to enable padding. Our results suggest that recommended padding approaches are less effective than expected and that resolver operators are not sufficiently aware about this feature.
