description: This dissertation presents a analysis of negation in a spoken language, i.e., Khuzestani Arabic (KhA), and a sign language, i.e., Sadat Tawaher Sign Language (STSL). STSL emerged naturally without any intervention such as deaf education after a man lost his hearing around sixty years ago in a small village named Sadat Tawaher located in southwestern Iran. After this incident, the deaf person's family came up with a gestural system to communicate with him. Despite the fact that everyone in Sadat Tawaher, including the deaf person's family, speaks KhA, I hypothesized that KhA and STSL possess different grammatical ways to express negation. Data gathered using signed productions, story-telling, and grammaticality judgments clearly showed that negation is preverbal in KhA but sentence-final in STSL.

Περιγράφονται αναλυτικά ο εντοπισμός κινδύνων, απειλών αλλά κυρίως εγκλημάτων που αφορούν τις οδικές μεταφορές. Με στόχο την κατανόηση των κινδύνων αυτών μελετώνται και παρουσιάζονται εκθέσεις διεθνών οργανισμών, εταιρειών αλλά και νομοθετικών οργάνων όπως είναι οι αποφάσεις της Ευρωπαϊκής Ένωσης με κύριο όργανο την Ευρωπαϊκή Επιτροπή, που αποτελούν τους πυλώνες σε ότι αφορά στην εφαρμογή μέτρων προστασίας τόσο των εμπορευμάτων όσο και των οδηγών. Εν συνέχεια των παραπάνω σημειώνεται ότι η ανάγκη για την εύρεση νέων συστημάτων αλλά και δικλείδων ασφαλείας για την προστασία των προϊόντων προέκυψε μέσω της εκτενούς μελέτης στα ήδη υπάρχοντα συστήματα μεταφοράς και στις ελλείψεις που διαπιστώνονται καθημερινά λόγω μη επαρκών υποδομών, έλλειψης σχετικών αποφάσεων αλλά και συνεργασιών μεταξύ των οργανισμών τόσο στο εσωτερικό μίας χώρας όσο και σε διεθνές περιβάλλον. Στο δεύτερο μέρος της παρούσας διπλωματικής παρουσιάζονται μελέτες περίπτωσης που κάνουν χρήση λογισμικού, δηλαδή νέων τεχνολογιών αλλά και κλασσικότερων μεθόδων, που όλες όμως στοχεύουν στην αντιμετώπιση των εγκλημάτων που οδηγούν στην απώλεια φορτίων και την εξάλειψή τους.

description: Magnetic fields are a standard tool in the toolbox of every physicist, and are required for the characterization of materials, as well as the polarization of spins in nuclear magnetic resonance or electron paramagnetic resonance experiments. Quite often a static magnetic field of sufficiently large, but fixed magnitude is suitable for these tasks. Here we present a permanent magnet assembly that can achieve magnetic field strengths of up to 1.5T over an air gap length of 7mm. The assembly is based on a Halbach array of neodymium (NdFeB) magnets, with the inclusion of the soft magnetic material Supermendur to boost the magnetic field strength inside the air gap. We present the design, simulation and characterization of the permanent magnet assembly, measuring an outstanding magnetic field stability with a drift rate of |D| < 2.8 ppb/h. Our measurements demonstrate that this assembly can be used for spin qubit experiments inside a dilution refrigerator, successfully replacing the more expensive and bulky superconducting solenoids.

description: Azimuthal correlations of high-pT charged hadron pairs from (di-)jet-fragmentation are studied at mid-rapidity in Au+Au collisions at vsNN=200 GeV. The distribution of jet-associated partner hadrons (1.0< pT <2.5 GeV/c) per trigger hadron (2.5< pT <4.0 GeV/c) is found to vary with collision centrality, both in shape and in yield, indicating a significant effect of the nuclear collision medium on the (di-)jet fragmentation process.

Συγκεκριμένα, το Hyperledger Fabric αποτελεί λογισμικό ανοικτού κώδικα (open source software) το οποίο παρέχει την υποδομή για την κατασκευή private permissioned blockchain δικτύων και είναι σχεδιασμένο επί το πλείστον για χρήση στον τομέα των επιχειρήσεων. Στα πλαίσια της έρευνάς μας, θα εξετάσουμε κάθε οντότητα σε ένα Hyperledger Fabric δίκτυο ξεχωριστά για να διαπιστώσουμε πιθανές ευπάθειες, με κύριο γνώμονα τα τρία βασικά κριτήρια ασφάλειας, την Εμπιστευτικότητα (Confidentiality), την Ακεραιότητα (Integrity) και την Διαθεσιμότητα (Availability). Παράλληλα, θα συγκρίνουμε τα ευρήματα μας με την ήδη υπάρχουσα βιβλιογραφία που αφορά προηγούμενες εκδόσεις του Hyperledger Fabric, ώστε να διαπιστώσουμε αν γνωστές ευπάθειες αυτών έχουν πλέον διορθωθεί. Συνεπώς, η παρούσα εργασία αποτελεί μια προσπάθεια για ολοκληρωμένη και σφαιρική διερεύνηση των χαρακτηριστικών του Hyperledger Fabric από την σκοπιά της ασφάλειας, συνδυάζοντας, επεκτείνοντας και επιβεβαιώνοντας τις μέχρι τώρα δημοσιευμένες αναλύσεις και πειράματα με σκοπό την αξιολόγηση του συνολικού επιπέδου ασφάλειας στην καινούρια έκδοση.

description: Dieses Discussion Paper enthält die Kurzfassungen der Beitrsge, die im Rahmen des Workshops zur Agrarentwicklung in Mittel- und Osteuropa fur Doktoranden und Post-Doc's vorgestellt und diskutiert werden sollen. Dieser Workshop mochte Nachwuchswissenschaftlern die Moglichkeit geben, Ihre Forschungsvorhaben zu prssentieren und zu diskutieren. Er findet erstmalig in dieser Form am IAMO statt. Die folgenden Kurzfassungen sollen allerdings nicht nur als Diskussionsgrundlage fur den Workshop dienen, sondern auch einen Querschnittsuberblick uber die gegenwsrtige Nachwuchsforschung im Agrarbereich zu Mittel- und Osteuropa vermitteln. Wir denken, dass ein breites Spektrum von relevanten Themen bearbeitet wird. Dies entspricht einerseits dem interdisziplinären Ansatz in der Agrarökonomie, andererseits zeigt es, dass die Diskussion mit Nachbarwissenschaften wie Politikwissenschaften oder Geographie fruchtbar geführt werden kann. Hervorzuheben ist weiterhin der hohe Anteil von Wissenschaftlern aus dem europäischen Ausland, die am Workshop teilnehmen. Dieser Umstand dokumentiert die europäische Dimension des Themas und unterstreicht die Rolle des IAMOs als Forum des wissenschaftlichen Austausches. Wir wünschen uns, dass der Workshop zur Agrarentwicklung in Mittel- und Osteuropa für Doktoranden und Post-Doc's zu fruchtbaren Diskussionen anregt und hoffen, dass die vorliegende Zusammenstellung dazu beitragt, den Erfahrungsaustausch auch uber den engeren Kreis der unmittelbar Beteiligten hinaus zu fördern.

description: The purpose of this study was to develop and validate an evaluation instrument for tablet arm chairs based on ergonomic requirements, focused on user perceptions and using Item Response Theory (IRT). This exploratory study involved 1,633 participants (university students and professors) in four steps: a pilot study (n=26), semantic validation (n=430), content validation (n=11) and construct validation (n=1,166). Samejima’s graded response model was applied to validate the instrument. The results showed that all the steps (theoretical and practical) of the instrument’s development and validation processes were successful and that the group of remaining items (n=45) had a high consistency (0.95). This instrument can be used in the furniture industry by engineers and product designers and in the purchasing process of tablet arm chairs for schools, universities and auditoriums.

description: In August 1998 the Russian foreign exchange market and financial system collapsed. As a consequence the rouble devaluated in real terms against the currencies of the main trade partners, generating an output push in the agri-food sector. This improved the financial health of most producer, thus "opening a window of opportunity" enhancing the long run growth prospects. But, it is not apparent whether the agri-food sector make use of the enhanced circumstances. Insufficient incentive systems due to non-enforcement of legal rules within firms and farms and lack of credibility of Russian government promote a rent-seeking behaviour of employer and employees. Thus, it could be expected, that the non-price competitiveness of Russian products will rather worsen than getting better.
End-to-end Handwritten Paragraph Text Recognition Using a Vertical Attention Network

description: Unconstrained handwritten text recognition remains challenging for computer vision systems. Paragraph text recognition is traditionally achieved by two models: the first one for line segmentation and the second one for text line recognition. We propose a unified end-to-end model using hybrid attention to tackle this task. This model is designed to iteratively process a paragraph image line by line. It can be split into three modules. An encoder generates feature maps from the whole paragraph image. Then, an attention module recurrently generates a vertical weighted mask enabling to focus on the current text line features. This way, it performs a kind of implicit line segmentation. For each text line features, a decoder module recognizes the character sequence associated, leading to the recognition of a whole paragraph. We achieve state-of-the-art character error rate at paragraph level on three popular datasets: 1.91% for RIMES, 4.45% for IAM and 3.59% for READ 2016. Our code and trained model weights are available at https://github.com/FactoDeepLearning/VerticalAttentionOCR.

Industrial Organization

description: The food industry is one of the most important sectors in the Latvian economy. However, due to its close links to agriculture, the structural crisis in the processing sector is the main obstacle to increasing output, productivity and profitability in the entire agricultural sector. Based on the structure-conduct-performance framework developed by the economic theory of industrial organisation, the objective of the present discussion paper is to identify those economic conditions that are giving rise to the low degree of competitiveness in Latvia's food industry. For this purpose, the paper analyses the impact of the macroeconomic environment, the change in demand and input supply conditions, and the privatisation process on the development of the food industry. The analysis shows that, although major progress has been made in macroeconomic stabilisation, privatisation and institution building, the efficiency and performance of this important part of the Latvian agrofood chain are far from perfect. Current problems of the Latvian food industry that result in low profitability are increasing input costs, low labour productivity, low domestic and foreign investment activities and excess capacities. The main causes for these are unfavourable interest rates on bank loans, ineffective corporate governance in privatised firms, and deficiencies in the building and implementation of institutions.

description: We present the Fundamental Plane (FP) for 38 early-type galaxies in the two rich galaxy clusters RXJ0152.7-1357 (z=0.83) and RXJ1226.9+3332 (z=0.89), reaching a limiting magnitude of M_B =-19.8 mag in the rest frame of the clusters. While the zero point offset of the FP for these high redshift clusters relative to our low redshift sample is consistent with passive evolution with a formation redshift of z_form ~ 3.2, the FP for the high redshift clusters is not only shifted as expected for a mass-independent z_form, but rotated relative to the low redshift sample. Expressed as a relation between the galaxy masses and the mass-to-light ratios the FP is significantly steeper for the high redshift clusters than found at low redshift. We interpret this as a mass dependency of the star formation history, as has been suggested by other recent studies. The low mass galaxies (10^10.3 M_sun) have experienced star formation as recently as z ~ 1.35 (1.5 Gyr prior to their look back time), while galaxies with masses larger than 10^11.3 M_sun had their last major star formation episode at z > 4.5.

description: Activation of the hypoxia-inducible factor (HIF)-pathway in hepatocellular carcinoma (HCC) induces therapy resistant tumours, characterized by increased liver progenitor cell (LPCs) characteristics and poor prognosis. We previously reported corresponding results in mice with HCC in which hypoxia was mimicked by prolyl hydroxylase domain (PHD) inhibition. Here, we aimed at investigating whether induction of LPC characteristics occurs during the onset of hepatocarcinogenesis and if this is associated with activation of Notch signalling. Dietheylnitrosamine (DEN) was used to induce hepatic tumours in PHD2 haplodeficient (PHD2+/-) mice which were euthanized at 5, 10, 15 and 17 weeks following DEN during neoplastic transformation, before tumour formation. Neoplasia and mRNA expression of LPC and Notch markers were evaluated by histology and qPCR on isolated livers. PHD2 haplodeficiency resulted in enhanced expression of HIF target genes after 17 weeks of DEN compared to wild type (WT) littermates but had no effect on the onset of neoplastic transformation. The mRNA expression of Afp and Epcam was increased at all time points following DEN whereas CK19, Prom1 and Notch3 were increased after 17 weeks of DEN, without difference between PHD2+/- and WT mice. MDR1 mRNA expression was increased in all DEN treated mice compared to saline control with increased expression in PHD2+/- compared to WT from 15 weeks. These results indicate that the effects of PHD2 haplodeficiency on the expression of LPC and Notch markers manifest during tumour nodule formation and not early on during neoplastic transformation.

description: This study uses 125 responses from companies of all sizes headquartered in Germany, Switzerland, France and UK to reveal perceptions of the drivers of organisational agility. It further investigates current understanding of managing principles of multiple organisational dimensions such as culture, values, leadership, organisational structure, processes and others to achieve greater organisational agility. The data set is disaggregated into four major profiles of agile organisations: laggards, execution specialists, experimenters, and leaders. The approach to agile transformation is analysed by each of those profiles. While the positive effect from a more holistic approach is confirmed, leaders tend to focus more on processes and products rather than project work. Respondents perceive that IT, product development and research are most agile functions within their organisations, while human resources, finance and administration are considered being not agile. Further, organisations with higher levels of organisational agility tend use more than one agile scaling framework. Implications on theories of agile transformations and organisational design are discussed.

description: We show that a perfectly genuine tripartite EPR steerable assemblage can be distilled from partially genuine tripartite EPR steerable assemblages. In particular, we consider two types of hybrid scenarios: one-sided device-independent (1SDI) scenario (where one observer is untrusted, and other two observers are trusted) and two-sided device-independent (2SDI) scenario (where two observers are untrusted, and one observer is trusted). In both the scenarios, we show distillation of perfectly genuine steerable assemblage of three-qubit Greenberger-Horne-Zeilinger (GHZ) states or three-qubit W states from many copies of initial partially genuine steerable assemblages of the corresponding states. In each of these cases, we demonstrate that at least one copy of a perfectly genuine steerable assemblage can be distilled with certainty from infinitely many copies of initial assemblages. In case of practical scenarios employing finite copies, we show that the efficiency of our distillation protocols reaches near perfect levels using only a few number of initial assemblages.

On the spatial mean of the Poincare cycle

Subjects: subject: Probability (math.PR)

description: Let $X$ be a measure space and $T:X\to X$ a measurable transformation. For any measurable $E\subseteq X$ and $x\in E$, the possibly infinite return time is $n_E(x):=\inf\{n>0: T^n x\in E\}$. If $T$ is an ergodic tranformation of the probability space $X$, and $μ(E)>0$, then a theorem of M. Kac states that $\int_E n_E dμ=1$. We generalize this to any invertible measure preserving transformation $T$ on a finite measure space $X$, by proving independently, and nearly trivially that for any measurable $E\subseteq X$ one has $\int_E n_E dμ=μ(I_E)$, where $I_E$ is the smallest invariant set containing $E$. In particular this also provides a simpler proof of Poincaré's recurrence theorem.

description: Mustard (Brassica juncea) leaves are commonly consumed in different Asian and African countries. Cancer is a major burden of disease worldwide, and the colorectal and lung cancers are the leading cause of morbidity and mortality among cancers. In the current study, we aimed to investigate the effects of ethanol extract of mustard leaf (MLE) on the growth, angiogenic, and metastatic potentials of HCT116 colorectal carcinoma and H1299 non-small cell lung carcinoma cells in vitro. Treatment of HCT116 and H1299 cells with MLE inhibited cell growth in a dose-dependent manner (in the range of 175-700 μg/ml, by 39-86 %) and anchorage-independent colonization (at 700 μg/ml, by 56-86 %). Induction of apoptosis by MLE was evidenced by heterogeneous and condensed nucleus morphology, increased 4′,6-diamidino-2-phenylindole dihydrochloride staining intensity, and elevated sub-G1 cell population. In both HCT116 and H1299 cells, treatment with MLE markedly suppressed the secretion of key pro-angiogenic factors, such as vascular endothelial cell growth factor (by >92 %) and basic fibroblast growth factor (by 73-94 %). MLE was also effective in inhibiting critical events during metastasis, such as invasion (by 18-33 % in HCT116 and H1299), migration (45-82 % in H1299), and adhesion (by 17-45 % in HCT116 and H1299). These results indicate that MLE possesses in vitro anti-cancer activities against colon and lung cancers. It needs to be verified whether similar effects are reproduced in vivo.

description: Far infrared radiation absorption of a quantum dot with few electrons in an orthogonal magnetic field could monitor the crossover to the fully spin polarized state. A Rashba spin-orbit coupling can tune the energy and the spin density of the first excited state which has a spin texture carrying one extra unit of angular momentum. The spin orbit coupling can squeeze a flipped spin density at the center of the dot and can increase the gap in the spectrum.

description: The performance of Simultaneous Wireless Information and Power Transfer (SWIPT) is mainly constrained by the received Radio-Frequency (RF) signal strength. To tackle this problem, we introduce an Intelligent Reflecting Surface (IRS) to compensate the propagation loss and boost the transmission efficiency. This paper proposes a novel IRS-aided SWIPT system where a multi-carrier multi-antenna Access Point (AP) transmits information and power simultaneously, with the assist of an IRS, to a single-antenna User Equipment (UE) employing practical receiving schemes. Considering harvester nonlinearity, we characterize the achievable Rate-Energy (R-E) region through a joint optimization of waveform, active and passive beamforming based on the Channel State Information at the Transmitter (CSIT). This problem is solved by the Block Coordinate Descent (BCD) method, where we obtain the active precoder in closed form, the passive beamforming by the Successive Convex Approximation (SCA) approach, and the waveform amplitude by the Geometric Programming (GP) technique. To facilitate practical implementation, we also propose a low-complexity design based on closed-form adaptive waveform schemes. Simulation results demonstrate the proposed algorithms bring considerable R-E gains with robustness to CSIT inaccuracy and finite IRS states, and emphasize the importance of modeling harvester nonlinearity in the IRS-aided SWIPT design.

description: The purpose of this study is to determine the experimental uncertainties in measuring mass and cross section parameters of SUSY particles at a 500 GeV Linear Collider. In this study SUSY is a point in the focus point region of mSUGRA parameter space that is compatible with WMAP constraints on dark matter relic density. At this study point the masses of the squarks and sleptons are very heavy, and the only SUSY particles accessible at the Linear Collider would be the three lightest neutralinos, and the two lightest charginos: nino1, nino2, nino3, cino1+, cino2+, where nino1 is the lightest supersymmetric particle (LSP). The charginos or neutralinos may be pair produced, and the subsequent decay cascades to the LSP allow us to measure the SUSY couplings and mass spectrum. We find that by looking for the signature 2 jets plus 2 leptons plus missing energy we can determine the mass of the LSP to within 1 GeV uncertainty and that the mass differences of nino2 and nino3 with the LSP mass can be determined to better than 0.5 GeV.

description: We study alignment of grains by radiative torques. We found steep rise of radiative torque efficiency as grain size increases. This allows larger grains that are known to exist within molecular clouds to be aligned by the attenuated and reddened interstellar radiation field. In particular, we found that, even deep inside giant molecular clouds, e.g. at optical depths corresponding to less than Av of 10 large grains can still be aligned by radiative torque. This means that, contrary to earlier claims, far-infrared/submillimeter polarimetry provides a reliable tool to study magnetic fields of pre-stellar cores. Our results show that the grain size distribution is important for determining the relation between the degree of polarization and intensity.

description: We introduce a notion of `proChow group' of varieties, agreeing with the notion of Chow group for complete varieties and covariantly functorial with respect to arbitrary morphisms. We construct a natural transformation from the functor of constructible functions to the proChow functor, extending MacPherson's natural transformation. We illustrate the result by providing very short proofs of (a generalization of) two well-known facts on Chern-Schwartz-MacPherson classes: Kwiecinski's product formula, and the Ehlers-Barthel-Brasselet-Fieseler computation of Chern-Schwartz-MacPherson classes of toric varieties.

description: Dystonia is a neurological disorder characterized by excessive involuntary muscle contractions that lead to twisting movements. The exaggerated movements have been studied and have implicated basal ganglia as the point of origin. In more recent studies, the cerebellum has also been identified as the possible target of dystonia, in the search for alternative treatments. Tiagabine is a selective GABA transporter inhibitor, which blocks the reuptake and recycling of GABA. The study of GABAergic drugs as an alternative treatment for cerebellar induced dystonia has not been reported. In our study, tiagabine was i.p. injected into kainic acid induced, cerebellar dystonic adult rats, and the effects were compared with non-tiagabine injected and sham-operated groups. Beam walking apparatus, telemetric electromyography (EMG) recording, and histological verification were performed to confirm dystonic symptoms in the rats on post-surgery treatment. Involuntary dystonic spasm was observed with repetitive rigidity, and twisting movements in the rats were also confirmed by a high score on the dystonic scoring and a high amplitude on the EMG data. The rats with tiagabine treatment were scored based on motor amelioration assessed via beam walking. The result of this study suggests and confirms that low dose of kainic acid microinjection is sufficient to induce dystonia from the cerebellar vermis. In addition, from the results of the EMG recording and the behavioral assessment through beam walking, tiagabine is demonstrated as being effective in reducing dystonic spasm and may be a possible alternative therapeutic drug in the treatment of dystonia.

description: Colorectal cancer is one of the most prevalent cancers in different countries, including Iran. No comprehensive study has been done in the country for colorectal cancer, but information on the incidence and trends is essential to planning. This study aimed to evaluate the occurrence and morphology of colorectal cancer and its trend in Iran. This study was conducted using data from the national cancer registry system in Iran from 2003-2008. We used joinpoint regression analysis for assessing incidence time trends and morphology change percentage. Of all cases of colorectal cancer, 61.83 % were colon cancer, 27.54 % rectal cancer, 7.46 % rectosigmoid cancer, and 3.10 anal cancer. The most common histological types with the frequencies of 80.85 % was related to adenocar- cinoma, NOS. The Annual percentage changes (APC) in ASIR for colorectal cancer significantly increased in both men and women. APC in ASIR was 13.7 (CI: 10.5-17.1) in women and 16.4 (CI: 12.4-20.5) in men. APC of adenocarcinoma in villous adenoma showed significant declining trend (p<0.05), while APC of adenocarci- noma, NOS had a constant trend. The incidence of the cancer in recent years has increased in Iran because of changes in lifestyle and diet. Therefore, further studies are necessary to detect the cause of this cancer and per- form preventive measures.

Fractured reflections : rainforests, plantations and the Malaysian nation-state
Creators: name: Sioh, Maureen Kim Lian
Publisher: name: University of British Columbia
Year: 2009

description: This study examines how deforestation in Malaysia is framed as an economic issue fought out in the political arena using cultural codes as an entry point to examining the political tensions of contemporary Malaysia. Three themes recur throughout this work. The first theme concerns the centrality of resources in Malaysia's colonial and post-colonial political economy. The second theme concerns the displacement of the anxieties of national and cultural survival onto the contests over economic rights. And the third theme is the way collective memories 'flesh out' contemporary contests between the state and civil society. In the sense that the three themes are inter-related, this study traces the twinned construction, and opposition, of the two central ideas: of 'nature' in the form of the rainforest and 'race' in the guise of nation. In keeping with the role of memory in present-day social and political engagements, this study weaves both archival and contemporary material to trace the construction of the history, imagery and vocabulary that have been mapped onto the physical space of the rainforest. I explore the production of the cultural codes through this mapping process that are then used to articulate the contests over the rainforest. These codes are the consequence of negotiations that reflect the unstable alliances and inconsistent identities of contemporary Malaysia, and they are the legacies, albeit translated, of colonialism. In retracing the contests over and about the forests, I hope to shed some light on why Malaysians made, and continue to make, decisions that appear to work against them. The decisions affecting the fate of the rainforest reflects choices made about the kind of society Malaysians live with. Hence, the three core chapters of this study examine military, political/cultural and economic contests and negotiations surrounding the birth of the Malayan/Malaysian nation-state through their impacts on the rainforest. By acknowledging how much of Malaysia's contemporary politics is its colonial legacy, I hope to highlight the trade-off we have made between limited political engagement and development. To accept that we cannot protect basic rights as the price of economic success is to continue to live within the racist framework of colonialism that human rights are only for some humans.
