description: Είναι αναμφισβήτητο ότι η πανδημία COVID-19 αποτέλεσε μια από τις μεγαλύτερες κρίσεις που έχει αντιμετωπίσει η σύγχρονη ανθρωπότητα. Επηρέασε, παγκοσμίως και σε μεγάλο βαθμό, τις ζωές των ανθρώπων, τις επιδόσεις των εταιριών, την παραγωγή αγαθών και την παγκόσμια οικονομία. Όμως, μια κρίση δύναται να παρουσιάσει και ευκαιρίες για μετάβαση σε ένα πιο βιώσιμο μέλλον. Στην έρευνα αυτή, μέσα από εκτεταμένη βιβλιογραφική ανάλυση, μελέτη και έπειτα από μια αναφορά στο θεωρητικό υπόβαθρο των εφοδιαστικών αλυσίδων, θα αναλυθούν οι σημαντικότερες προκλήσεις και επιπτώσεις που εμφανίστηκαν, κατά τη διάρκεια της πανδημίας, στη λειτουργικότητα, τη βιωσιμότητα και την ανθεκτικότητα των παγκόσμιων εφοδιαστικών αλυσίδων. Επιπρόσθετα, θα παρουσιαστούν μερικοί τρόποι αντιμετώπισης των επιπτώσεων αυτών, οι οποίοι αναπτύχθηκαν υπό την πίεση των υγειονομικών περιορισμών. Εν τέλη, θα παρατεθούν οι κυριότερες πρωτοβουλίες που πρέπει να λάβουν οι επιχειρήσεις, με σκοπό να ανταπεξέλθουν στις συνεχείς αλλαγές που πραγματοποιούνται στη μετά COVID-19 εποχή και θα γίνει μια προσπάθεια «χαρτογράφησης» του μέλλοντος των παγκόσμιων εφοδιαστικών αλυσίδων.
description: It is undeniable that the COVID-19 pandemic was one of the greatest crises that modern humanity has ever faced. It affected, globally and to a large extent, people’s lives, corporate performance, the production of goods and the global economy. However, a crisis can also present opportunities for a transition to a more sustainable future. In this research, through an extensive literature analysis, study, and a review of theoretical background of supply chains, the major challenges and impacts that emerged during the pandemic on the functionality, the sustainability, and the resilience of Global Supply Chains (GSC) will be analyzed. In addition, some ways to address these impacts, that were developed under the pressure of health constraints, will be presented. Finally, the main initiatives that companies need to take to cope with the constant changes taking place in the post COVID-19 era will be listed and an attempt will be made to “map” the future of global supply chains.

description: We report the results of a synthetic spectral analysis of Hubble STIS spectra of the AM CVn-type cataclysmic variable CP Eri obtained when the system was in quiescence. The FUV spectrum is best fitted by a helium-dominated, hybrid composition (DBAZ) white dwarf with Teff=17,000K +/- 1000K, log g=8, He abundance ~1000 times solar, H abundance ~0.1 times solar, metallicity Z ~ 0.05 times solar, V sin i = 400 km/s. This is the first directly detected primary white dwarf in any AM CVn and the surface abundance and rotation rate for the white dwarf primary are the first to be reported for AM CVn systems. The model-predicted distance is ~ 1000 pc. The spectral fits using pure He photospheres or He-rich accretion disks were significantly less successful. Based upon the analysis of our FUV spectra, CP Eri appears to contain a hybrid composition DBAZ white dwarf with a metallicity which sets it apart from the other two AM Cvn stars which have been observed in quiescence and are metal-poor. The implications of this analysis for evolutionary channels leading to AM CVn systems are discussed.

description: Η πρωτεϊνική κινάση SRPK1, το πιο μελετημένο μέλος της οικογένειας των SR πρωτεϊνικών κινασών, παίζει καθοριστικό ρόλο σε μια σειρά από κυτταρικές λειτουργίες όπως το μάτισμα των mRNA, η πρόσδεση της ετεροχρωματίνης στον πυρηνικό φάκελλο και η αντικατάσταση των ιστονών από την πρωταμίνη 1 κατά τη διάρκεια της σπερμιογένεσης. Αν και φέρει δύο σήματα πυρηνικής εντόπισης, η SRPK1 κατανέμεται τόσο στον πυρήνα όσο και στο κυτταρόπλασμα. Σύμφωνα με το ισχύον μοντέλο η SRPK1, μέσω της ενδιάμεσης συνδετικής της αλληλουχίας που λειτουργεί ως «κυτταροπλασματική άγκυρα», συνδέεται στο σύμπλοκο Hsp70/Hsp90 το οποίο αφ’ ενός βοηθάει να πάρει την ενεργή της διαμόρφωση αλλά ταυτόχρονα την καθηλώνει στην περιοχή του κυτταροπλάσματος. Υπό συνθήκες στρες η κινάση απελευθερώνεται από το σύμπλοκο των σαπερονινών -με άγνωστο έως τώρα μηχανισμό- και μεταφέρεται στον πυρήνα του κυττάρου. Στην παρούσα εργασία προτείνουμε ότι η ανάπτυξη ενός δισουλφιδικού δεσμού μεταξύ των κυστεϊνών 356 και 455 στη συνδετική περιοχή της κινάσης είναι υπεύθυνη για την είσοδό της στον πυρήνα. Ο δισουλφιδικός αυτός δεσμός συμβάλλει ακόμα στην σταθεροποίηση και αύξηση της δραστικότητας της κινάσης.
description: SRPK1, the prototype of serine-arginine protein kinases, has been implicated in a variety of cellular processes, such as constitutive and alternative splicing of mRNA, hetechromatin association with the nuclear envelope and replacement of histones by protamine 1 during spermiogenesis. Despite the fact that SRPK1 contains two nuclear localization signals, and the majority of its substrates are nuclear proteins, the kinase is distributed between the cytoplasm and the nucleus of mammalian cells. According to a current model, SRPK1, through its spacer domain, forms a complex with the Hsp70/Hsp90 machinery, which may initially assist folding of the kinase into an active conformation. The complex then performs the function of restricting the kinase in the cytoplasm. Importantly, the interaction of SRPK1 with the molecular chaperones could be modulated by a stress signal, resulting in the release and subsequent translocation of the kinase to the nucleus. In an attempt to address the question of how specific internal or external signals may modulate the dynamic interactions between SRPK1 and molecular chaperones, we demonstrate that the formation of a disulfide bond between cysteines 356 and 455 within its spacer domain resulted in translocation of the kinase to the nucleus. Furthermore, this disulfide bond has a positive impact both on the stability and activity of SRPK1.

description: Over land the vegetation canopy affects the microwave brightness temperature by emission, scattering and attenuation of surface soil emission. The questions addressed in this study are: 1) what is the transparency of the vegetation canopy for different biomes around the Globe at the low-frequency L-band?, 2) what is the seasonal amplitude of vegetation microwave optical depth for different biomes?, 3) what is the effective scattering at this frequency for different vegetation types?, 4) what is the impact of imprecise characterization of vegetation microwave properties on retrieval of soil surface conditions? These questions are addressed based on the recently completed one full annual cycle measurements by the NASA Soil Moisture Active Passive (SMAP) measurements.

description: We investigate the charge density wave phase in the strongly correlated Hubbard model without any other broken symmetry phase. Starting from the atomic Hamiltonian with no hopping, we generate quasiparticle operators corresponding to holons and doublons in the strongly correlated limit of the repulsive Hubbard model. We develop a real space composite operator formalism using the equation of motion technique to include the intersite hopping perturbatively. Our fully self-consistent calculation stabilizes multiple unidirectional translation symmetry broken states within the doping range $δ=0.07$ to $0.2$. The charge-ordered states become increasingly unfavorable with hole-doping. The unidirectional density waves manifest as periodic modulations of half-filled Mott regions separated by hole-rich regions. Notably, density wave solutions with periods of $3$ to $8$ lattice spacing remain energetically higher than those with larger periods. Quenched disorder on the charge-ordered states induces the merging of the Mott regions and, consequently, forms short-ranged charge modulations. The density of states shows signatures of strongly correlated Mott regions, potentially relevant to the physics of underdoped cuprates.

description: In this study the framework of the $τ$-$ω$ model is used to derive vegetation loss coefficients and canopy penetration depths from SMAP multi-temporal retrievals of vegetation optical depth, single scattering albedo and ICESat lidar vegetation heights. The vegetation loss coefficients serve as a global indicator of how strong absorption and scattering processes attenuate L-band microwave radiation. By inverting the vegetation loss coefficients, penetration depths into the canopy can be obtained that is displayed for the global forest reservoirs. A simple penetration index is formed combining vegetation heights and penetration depth estimates. The distribution and level of this index reveal that for densely forested areas the soil signal is attenuated considerably, which can affect the accuracy of soil moisture retrievals.

description: Sensitivity coefficients to temporal variation of the fine-structure constant alpha for transitions between the fine-structure (FS) sub-levels of the ground states of C I, Si I, S I, Ti I, Fe I, N II, Fe II, O III, S III, Ar III, Fe III, Mg V, Ca V, Na VI, Fe VI, Mg VII, Si VII, Ca VII, Fe VII, and Si IX are calculated. These transitions lie in the mid- and far-infrared regions and can be observed in spectra of high-redshift quasars and infrared bright galaxies with active galactic nuclei. Using FS transitions to study alpha-variation over cosmological timescale allows to improve the limit on $|Δα/α|$ by several times as compared to contemporaneous optical observations ($|Δα/α| < 10^{-5}$), and to suppress considerably systematic errors of the radial velocity measurements caused by the Doppler noise. Moreover, the far infrared lines can be observed at redshifts z > 10, far beyond the range accessible to optical observations (z < 4). We have derived a simple analytical expression which relates the FS intervals and the sensitivity of the FS transitions to the change of alpha.

Constructions of local and Pan-Indian elements in contemporary Stó:lō identity

Publisher: name: University of British Columbia
Year: 2009

description: This thesis investigates the concern caused to some members of the Stó:lō Nation by the increasing prevalence of Plains cultural traits and activities in the Stó:lō people's Fraser Valley territory of British Columbia. Competing presentations of Stó:lō identity are common, and the identity revealed is neither that of a traditional past, nor one which is fully pan-Indian. I describe that which is often over-looked in the literature: the local-level dilemmas aroused by Stó:lō identity construction. To do this, I recount the opinions of three Stó:lō educators and incorporate the writings on identity, political economy, and pan-tribalism. I am particularly concerned with the competitions between what is viewed locally as traditional Stó:lō culture, and a foreign, Plains pan-native culture. Contention exists around these available identities, and as a result, some Stó:lō people are working to understand and rationalize a pan-Indian presence with a unique Stó:lō heritage. Ultimately, I suggest that the Stó:lō are asserting a flexible and adaptive identity suitable to fit into contemporary political and economic demands.

description: Working with scalar field theories, we discuss choices of regulator that, inserted in the functional renormalization group equation, reproduce the results of dimensional regularization at one and two loops. The resulting flow equations can be seen as nonperturbative extensions of the $\overline{\text{MS}}\,$ scheme. We support this claim by recovering all the multicritical models in two dimensions. We discuss a possible generalization to any dimension. Finally, we show that the method also preserves nonlinearly realized symmetries, which is a definite advantage with respect to other regulators.

description: An analytic reversible Hamiltonian system with two degrees of freedom is studied in a neighborhood of its symmetric heteroclinic connection made up of a symmetric saddle-center, a symmetric orientable saddle periodic orbit lying in the same level of a Hamiltonian and two non-symmetric heteroclinic orbits permuted by the involution. This is a codimension one structure and therefore it can be met generally in one-parameter families of reversible Hamiltonian systems. There exist two possible types of such connections in dependence on how the involution acts near the equilibrium. We prove a series of theorems which show a chaotic behavior of the system and those in its unfoldings, in particular, the existence of countable sets of transverse homoclinic orbits to the saddle periodic orbit in the critical level, transverse heteroclinic connections involving a pair of saddle periodic orbits, families of elliptic periodic orbits, homoclinic tangencies, families of homoclinic orbits to saddle-centers in the unfolding, etc. As a byproduct, we get a criterion of the existence of homoclinic orbits to a saddle-center.

description: We report on a study of complementarity in a two-terminal "closed-loop" Aharonov-Bohm interferometer. In this interferometer, the simple picture of two-path interference cannot be applied. We introduce a nearby quantum point contact to detect the electron in a quantum dot inserted in the interferometer. We found that charge detection reduces but does not completely suppress the interference even in the limit of perfect detection. We attribute this phenomenon to the unique nature of the closed-loop interferometer. That is, the closed-loop interferometer cannot be simply regarded as a two-path interferometer because of multiple reflections of electrons. As a result, there exist indistinguishable paths of the electron in the interferometer and the interference survives even in the limit of perfect charge detection. This implies that charge detection is not equivalent to path detection in a closed-loop interferometer. We also discuss the phase rigidity of the transmission probability for a two-terminal conductor in the presence of a detector.

description: This paper proposes a novel approach that employs error amplification and ADC-based dual-mixer time-difference (ADC-based-DMTD) technique for high-precision locking of laser repetition frequency with compact size. This electronic system consists of two main components: a digitized error amplification module (EAM) and an FPGA-based digital frequency locking module (DFLM). The EAM mainly integrates a configurable frequency generator (CFG), a configurable frequency multiplier (CFM) and a mixer to process the laser pulses and a high-stability reference source (e.g., an atomic clock), enabling high-precision locking of pulse lasers operating at different repetition frequencies. By employing frequency multiplication and mixing, the EAM amplifies the laser's frequency error and performs frequency down-conversion, enhancing measurement sensitivity and reducing the hardware requirements of the back-end. The DFLM receives the EAM outputs by using an ADC-based-DMTD method to precisely measure frequency errors, then the digital proportional-integral-derivative (PID) controller provides feedback to achieve accurate frequency locking. Initial testing with a voltage-controlled oscillator (VCO) demonstrated excellent locking performance, achieving an Allan deviation of $9.58 \times 10^{-14}$ at 10 seconds and a standard deviation (STD) of 7.7 \textmu Hz root mean square (RMS) after locking, marking a five-order-of-magnitude stability enhancement. In laboratory experiments with a custom-built femtosecond fiber laser, the system achieved robust locking of the repetition frequency, with a stability improvement from $1.51 \times 10^{-7}$ to $1.12 \times 10^{-12}$ at a 10-second gate time and an STD of 0.43 mHz RMS after locking.

We use a hierarchical approach, accounting microscopically for the cluster's degrees of freedom and more coarsely for the matrix. The dynamical polarizability of the Ar atoms and the strong Pauli-repulsion exerted by the Ar-electrons are taken into account. We discuss the impact of the matrix on the cluster gross properties and on its optical response. We then consider a realistic case of irradiation by a moderately intense laser and discuss the impact of the matrix on the hindrance of the explosion, as well as a possible pump probe scenario for analyzing dynamical responses.

description: The right to early repayment already formed part of Directive 87/102/EEC. Nevertheless, the rules of the Member States specifying the consequences of early repayment, and in particular the creditor‘s claim for compensation, differ greatly, and the new detailed rules established by Directive 2008/48/EC which has been incorporated into Greek Law with Ministerial Decision Ζ1-699/2010 were meant to harmonize the laws of the Member States in this field and provide to the consumer a higher level of protection. The basic rule of Article 16§1 is that consumer is entitled at any time to discharged fully or partially his obligations under a credit agreement, and that in such case, he shall be entitle to reduction in the total cost of credit, such reduction consisting of the interest and the costs for the remaining duration of the contract. In return, the creditor is entitled through the Article 16§2 to fair and objectively justified compensation for possible costs directly linked to early repayment of credit, according however to the terms, limitations and exemptions that are predicted particularly in the Article 16§§§§ 2, 3, 4 and 5.

description: We study attractor mechanism in extremal black holes of Einstein-Born-Infeld theories in four dimensions. We look for solutions which are regular near the horizon and show that they exist and enjoy the attractor behavior. The attractor point is determined by extremization of the effective potential at the horizon. This analysis includes the backreaction and supports the validity of non-supersymmetric attractors in the presence of higher derivative interactions in the gauge field part.

description: We demonstrate the utility and constraining power of a new statistic for investigating galaxy bias: the galaxy-lensing phase difference. The statistic consists in taking the differences of the phases of the harmonic wave-modes between the weak lensing convergence field and the galaxy count field. We use dark matter simulations populated with galaxies up to redshift $z=1$ to test the performance of this estimator. We find that phase differences are sensitive to the absolute value of the second order bias ($c_2=b_2/b_1$), and demonstrate why this is the case. For a $\sim$1500 sq. deg. galaxy survey we recover $c_2$ with an error of approximately $0.1$ for a wide range of $c_2$ values; current constraints from redshift surveys have errors of 0.1-0.6 depending on redshift. This new statistic is therefore expected to provide constraints for $c_2$ which are complementary and competitive with constraining power by the conventional estimators from the power spectrum and bispectrum. For the Dark Energy Survey (DES), we predict leading measurements of second-order bias.

description: Today, we know ~4330 exoplanets orbiting their host stars in ~3200 planetary systems. The diversity of these exoplanets is large, and none of the known exoplanets is a twin to any of the solar system planets, nor is any of the known extrasolar planetary systems a twin of the solar system. Such diversity on many scales and structural levels requires fundamental theoretical approaches. Large efforts are underway to develop individual aspects of exoplanet sciences, like exoplanet atmospheres, cloud formation, disk chemistry, planet system dynamics, mantle convection, mass loss of planetary atmospheres. The following challenges need to be addressed in tandem with observational efforts. They provide the opportunity to progress our understanding of exoplanets and their atmospheres by exploring our models as virtual laboratories to fill gaps in observational data from different instruments and missions, and taken at different instances of times: Challenge a) Building complex models based on theoretical rigour that aim to understand the interactions of atmospheric processes, to treat cloud formation and its feedback onto the gas-phase chemistry and the energy budget of the planetary atmosphere moving away from solar-system inspired parameterisations. Challenge b) Enabling cloud modelling based on fundamental physio-chemical insights in order to be applicable to the large and unexplored chemical, radiative and thermodynamical parameter range of exoplanets in the universe. Challenge b) will be explored in this chapter of the book ExoFrontiers.

description: The Gell-Mann $λ$ matrices for Lie algebra su(3) are the natural basis for the Hilbert space of Hermitian operators acting on the states of a three-level system(qutrit). So the construction of EWs for two-qutrit states by using these matrices may be an interesting problem. In this paper, several two-qutrit EWs are constructed based on the Gell-Mann matrices by using the linear programming (LP) method exactly or approximately. The decomposability and non-decomposability of constructed EWs are also discussed and it is shown that the $λ$-diagonal EWs presented in this paper are all decomposable but there exist non-decomposable ones among $λ$-non-diagonal EWs.

description: Αντικείμενο της παρούσας εργασίας αποτελεί το φαινόμενο της σωματεμπορίας, ως μορφή της εμπορίας ανθρώπων . Αρχικά αναλύονται έννοιες σχετιζόμενες με τη σωματεμπορία και περιγράφονται τα νομοθετικά μέτρα που έχουν ληφθεί σε εθνικό και διεθνές επίπεδο για την πρόληψη και αντιμετώπισή της. Στη συνέχεια αναλύεται το αδίκημα της σωματεμπορίας, όπως αυτό τυποποιείται στον Ποινικό Κώδικα, καθώς και οι διακεκριμένες μορφές αυτού. Κατόπιν αναφέρονται οι πιο συχνά εμφανιζόμενες περιπτώσεις συρροής της σωματεμπορίας με άλλα αδικήματα, όπως η συμμετοχή σε εγκληματική οργάνωση και η μαστροπεία. Ακολουθεί παράθεση της σχετικής νομολογίας, με κριτική αποτίμηση αυτής και περιγραφή των προβλημάτων του θεσμικού πλαισίου της εμπορίας ανθρώπων. Τέλος, αφιερώνεται ένα κεφάλαιο στην νέα οδηγία της Ευρωπαϊκής Ένωσης για την εμπορία ανθρώπων και τα ζητήματα που ανακύπτουν μετά από αυτήν για την ελληνική έννομη τάξη και ακολουθούν κάποιες προτάσεις για τη βελτίωση του νομικού καθεστώτος καταπολέμησης της εμπορίας ανθρώπων.
description: Purpose of this essay is the phenomenon of trafficking with the purpose of sexual exploitation, as a form of human trafficking. At first, concepts related to human trafficking are analyzed and legislative measures taken at national and international level for the prevention and treatment of trafficking are described. Then, the crime of trafficking is analyzed, as formalized in the Criminal Code, as well as the distinct forms of it. Then the most frequently occurring cases of influx of trafficking with other criminal offences are listed, such as participation in a criminal organization and pimping. Citing the relevant case law follows, with a critical assessment of it and description of the problems of the institutional framework of human trafficking. Finally, a chapter is devoted in the new EU directive on trafficking and the issues that arise after this for the Greek legal order, followed by some suggestions for improving the legal system to combat trafficking.

description: Gamma-ray bursts can be divided into three groups ("short", "intermediate", "long") with respect to their durations. The third type of gamma-ray bursts - as known - has the intermediate duration. We show that the intermediate group is the softest one. An anticorrelation between the hardness and the duration is found for this subclass in contrast to the short and long groups.

description: Στην παρούσα εργασία μελετήθηκαν 44 ζώα με μετατραυματική κοιλιοκήλη, 22 σκύλοι και 22 γάτες, που προσκομίστηκαν στην Κλινική των ζώων συντροφιάς της Κτηνιατρικής Σχολής του ΑΠΘ, τη χρονική περίοδο Ιανουάριος 2000 – Απρίλιος 2010. Τα 32 ζώα ανήκαν σε ακαθόριστη φυλή και η ηλικία τους κυμαινόταν από 0,15 έως 15 έτη. Τα 20 από τα 44 ζώα ήταν γένους θηλυκού και τα 23 γένους αρσενικού. Στο 43,18% των περιστατικών η αιτία πρόκλησης της κήλης ήταν τροχαίο ατύχημα, στο 22,72% δήγματα σκύλου, στο 2,72% πτώση από ύψος. Κατά την προσκόμιση των ζώων στην κλινική στο 88,63% αυτών υπήρχαν κλινικά συμπτώματα συμβατά με κήλη. Στο 40,9% των ζώων δεν διαπιστώθηκαν συνοδά τραύματα. Στα ζώα που παρουσίασαν συνοδά τραύματα αυτά αφορούσαν στο 65,21% το μυοσκελετικό ή το νευρικό σύστημα, στο 13% το αναπνευστικό σύστημα, στο 8,69% το γεννητικό σύστημα και στο 8,69% το δέρμα. Στο 75% των ζώων η κήλη αντιμετωπίστηκε με χειρουργική αποκατάσταση της ρήξης του κοιλιακού τοιχώματος. Στο 27,27% των ζώων που χειρουργήθηκαν εμφανίστηκαν μετεγχειρητικές επιπλοκές όπως διάσπαση του τραύματος του δέρματος, υποτροπή της κήλης, εμφάνιση αιματώματος / οιδήματος στην τομή, εμφάνιση περιτονίτιδας και εμφάνιση συριγγίου λόγω ύπαρξής ξένου σώματος.
description: Forty four cases, 22 dogs and 22 cats, with traumatic abdominal herniation, that were presented between January 2000 and April 2010 were included in the study. Twenty animals were females and 32 were males and their age ranged from 0.15 to 15 years. Forty three percent of the traumatic abdominal hernias were the result of vehicular trauma, 22.72% resulted from bite wounds inflicted by another dog and 2.72% were the result of fall. An abdominal herniation was identified during the initial physical examination in 88.63% of the cases. Sixty five percent of the animals had concurrent orthopedic and neurological trauma, 13% had respiratory tract trauma, 8.69% had genitourinary system trauma and 8.69% had skin trauma. Seventy five percent of the cases had surgical reconstruction of the hernia. Postoperative complications appeared in 27.27% of the animals and included wound dehiscence, hernia recurrence, hematoma or seroma formation, peritonitis and skin sinus associated with a foreign body. Fort five percent of the dogs and 56% of the cats had a good outcome after having a follow-up ranged from 0.1 -108 months and 0.1 – 78 months respectively.

description: Goal: We consider the problem of automatically grouping logs of runs that failed for the same underlying reasons, so that they can be treated more effectively, and investigate the following questions: (1) Does an approach developed to identify problems in system logs generalize to identifying problems in continuous deployment logs? (2) How does dimensionality reduction affect the quality of automated log clustering? (3) How does the criterion used for merging clusters in the clustering algorithm affect clustering quality? Method: We replicate and extend earlier work on clustering system log files to assess its generalization to continuous deployment logs. We consider the optional inclusion of one of these dimensionality reduction techniques: Principal Component Analysis (PCA), Latent Semantic Indexing (LSI), and Non-negative Matrix Factorization (NMF). Moreover, we consider three alternative cluster merge criteria (Single Linkage, Average Linkage, and Weighted Linkage), in addition to the Complete Linkage criterion used in earlier work. We empirically evaluate the 16 resulting configurations on continuous deployment logs provided by our industrial collaborator. Results: Our study shows that (1) identifying problems in continuous deployment logs via clustering is feasible, (2) including NMF significantly improves overall accuracy and robustness, and (3) Complete Linkage performs best of all merge criteria analyzed. Conclusions: We conclude that problem identification via automated log clustering is improved by including dimensionality reduction, as it decreases the pipeline's sensitivity to parameter choice, thereby increasing its robustness for handling different inputs.

description: Whole Slide Image (WSI) classification has very significant applications in clinical pathology, e.g., tumor identification and cancer diagnosis. Currently, most research attention is focused on Multiple Instance Learning (MIL) using static datasets. One of the most obvious weaknesses of these methods is that they cannot efficiently preserve and utilize previously learned knowledge. With any new data arriving, classification models are required to be re-trained on both previous and current new data. To overcome this shortcoming and break through traditional vision modality, this paper proposes the first Vision-Language-based framework with Queryable Prototype Multiple Instance Learning (QPMIL-VL) specially designed for incremental WSI classification. This framework mainly consists of two information processing branches: one is for generating bag-level features by prototype-guided aggregation of instance features, while the other is for enhancing class features through a combination of class ensemble, tunable vector and class similarity loss. The experiments on four public WSI datasets demonstrate that our QPMIL-VL framework is effective for incremental WSI classification and often significantly outperforms other compared methods, achieving state-of-the-art (SOTA) performance. Our source code is publicly available at https://github.com/can-can-ya/QPMIL-VL.

description: Το αντικείμενο της παρούσας εργασίας είναι η σχέση της σκέψης του Κορνήλιου Καστοριάδη με τον κοινωνικό κονστρουξιονισμό (social constructionism). Αρχικά αναφερόμαστε στα βασικά σημεία της κονστρουξιονιστικής επιχειρηματολογίας. Στη συνέχεια περιγράφουμε το περιεχόμενο κάποιων βασικών εννοιών της σκέψης του Καστοριάδη. Έπειτα προσπαθούμε να εξετάσουμε το κατά πόσο ορισμένες όψεις της καστοριαδικής σκέψης (οι παρατηρήσεις του σχετικά με το ζήτημα της γνώσης, με την ύπαρξη της φύσης αλλά και με την αθηναϊκή δημοκρατία του 5ου π.Χ. αιώνα) συμβαδίζουν με την κονστρουξιονιστική επιχειρηματολογία. Αναφερόμαστε επίσης στο κατά πόσο η καστοριαδική σκέψη μπορεί να γίνει σαφέστερα κατανοητή αν μελετηθεί ενταγμένη στο θεωρητικό πλαίσιο του κοινωνικού κονστρουξιονισμού.
description: The present essay examines the relationship between Cornelius Castoriadis’ thinking and social constructionism. Firstly we refer to the key points of the argumentation of social constructionism. We then describe the content of some of the most important concepts of Castoriadis’ thought . We then try to consider whether some aspects of Castoriadis’ thought (his remarks on the issue of knowledge, the existence of nature and also on the Athenian democracy of the fifth century BC) are in line with the constructionist argumentation. Furthermore a reference is made to whether Castoriadis’ thought can be more clearly understood if studied deeply integrated in the theoretical framework of social constructionism.
