description: We report vibrating coil magnetometry of the spin ice system Ho2Ti2O7 down to ~0.04 K for magnetic fields up to 5 T applied parallel to the [111] axis. History dependent behavior emerges below T*_0 ~ 0.6 K near zero magnetic field, in common with other spin ice compounds. In large magnetic fields we observe a magnetization plateau followed by a hysteretic metamagnetic transition. The temperature dependence of the coercive fields as well as the susceptibility calculated from the magnetization identify the metamagnetic transition as a line of first order transitions terminating in a critical endpoint at T*_m ~ 0.37 K, B*_m ~ 1.5 T. The metamagnetic transition in Ho2Ti2O7 is strongly reminiscent of that observed in Dy2Ti2O7, suggestive of a general feature of the spin ices.

description: Η παρούσα έρευνα αποσκοπούσε στη διερεύνηση της σχέσης χαρακτηριστικών προσωπικότητας των εργαζομένων, του εργασιακού περιβάλλοντος, και των στρατηγικών αντιμετώπισης σε περιστατικά εκφοβισμού, στην ανάπτυξη και έκβαση του εργασιακού εκφοβισμού. Επιπλέον, στόχος της μελέτης αποτελούσε η διερεύνηση συμπτωμάτων μετατραυματικής διαταραχής πικρίας, στους εργαζόμενους που βίωσαν εργασιακό εκφοβισμό. Τριακόσιοι δύο υπάλληλοι, τεσσάρων ιδιωτικών εταιρειών κλήθηκαν να απαντήσουν αρχικά σε ερωτηματολόγια που αξιολογούν το νευρωτισμό, την εξωστρέφεια και την ευσυνειδησία, το οργανωσιακό κλίμα και εργασιακή πίεση, όπως και τη μετατραυματική διαταραχή πικρίας. Επιπροσθέτως, υπάλληλοι οι οποίοι είχαν βιώσει εργασιακό εκφοβισμό τους τελευταίους έξι μήνες, κλήθηκαν να συμπληρώσουν έναν κατάλογο με στρατηγικές αντιμετώπισης του εργασιακού εκφοβισμού. Στη συνέχεια, πραγματοποιήθηκαν δέκα ημι-δομημένες συνεντεύξεις σε εργαζόμενους, οι οποίοι δήλωσαν ότι τους τελευταίους έξι μήνες είχαν υποστεί εργασιακό εκφοβισμό. Τα αποτελέσματα υποστηρίζουν ότι τόσο ο νευρωτισμός όσο και το εργασιακό περιβάλλον σχετίζονται με την εμφάνιση του εργασιακού εκφοβισμού και της μετατραυματικής διαταραχής πικρίας. Επιπλέον, οι στρατηγικές αντιμετώπισης, αναλόγως του είδους τους, φάνηκαν να συμβάλουν σε διαφορετική εξέλιξη του εργασιακού εκφοβισμού. This research aimed to investigate the relationship between employees’ personality traits, work environment, the reaction mechanisms, and the development of workplace bullying. In addition, the study is focused on investigating the symptoms of posttraumatic embitterment disorder of employees who experienced workplace bullying. Three-hundred-two employees of four private companies were initially asked to respond to questionnaires that assess neuroticism, extroversion, conscientiousness, organizational climate and work pressure, as also post-traumatic embitterment disorder. Furthermore, employees who had experienced workplace bullying in the last 6 months were asked to complete a list of coping strategies for workplace bullying. Following the questionnaires, ten semi-structured interviews were conducted with employees who, as they had stated, had experienced workplace bullying in the last six months. The results suggested that both neuroticism and workplace environment are associated with the development of workplace bullying and post-traumatic embitterment disorder. In addition, the coping strategies, depending on their types, appeared to contribute to a different development of workplace bullying.

description: The reachability problem for timed automata asks if there exists a path from an initial state to a target state. The standard solution to this problem involves computing the zone graph of the automaton, which in principle could be infinite. In order to make the graph finite, zones are approximated using an extrapolation operator. For reasons of efficiency in current algorithms extrapolation of a zone is always a zone and in particular it is convex. In this paper, we propose to solve the reachability problem without such extrapolation operators. To ensure termination, we provide an efficient algorithm to check if a zone is included in the so called region closure of another. Although theoretically better, closure cannot be used in the standard algorithm since a closure of a zone may not be convex. An additional benefit of the proposed approach is that it permits to calculate approximating parameters on-the-fly during exploration of the zone graph, as opposed to the current methods which do it by a static analysis of the automaton prior to the exploration. This allows for further improvements in the algorithm. Promising experimental results are presented.

description: In recent years, Deep Learning models have shown a great performance in complex optimization problems. They generally require large training datasets, which is a limitation in most practical cases. Transfer learning allows importing the first layers of a pre-trained architecture and connecting them to fully-connected layers to adapt them to a new problem. Consequently, the configuration of the these layers becomes crucial for the performance of the model. Unfortunately, the optimization of these models is usually a computationally demanding task. One strategy to optimize Deep Learning models is the pruning scheme. Pruning methods are focused on reducing the complexity of the network, assuming an expected performance penalty of the model once pruned. However, the pruning could potentially be used to improve the performance, using an optimization algorithm to identify and eventually remove unnecessary connections among neurons. This work proposes EvoPruneDeepTL, an evolutionary pruning model for Transfer Learning based Deep Neural Networks which replaces the last fully-connected layers with sparse layers optimized by a genetic algorithm. Depending on its solution encoding strategy, our proposed model can either perform optimized pruning or feature selection over the densely connected part of the neural network. We carry out different experiments with several datasets to assess the benefits of our proposal. Results show the contribution of EvoPruneDeepTL and feature selection to the overall computational efficiency of the network as a result of the optimization process. In particular, the accuracy is improved, reducing at the same time the number of active neurons in the final layers.
Geeks and creeps in no name land: triangulating anonymity, 2channel and Densha Otoko
Creators: name: Youssef, Sandra
Publisher: name: University of British Columbia
Year: 2009

description: This thesis examines anonymity online by analyzing the Japanese story “Densha Otoko” in the context of its locus of origin, the online forum 2channel. I argue that the collaborative value of the Densha Otoko narrative hinges on the technological infrastructure provided by its host forum. This infrastructure not only arises from specific technology developments, but also in turn emphasizes freedom of expression over identification. Focusing on the values linked to, and socialities engendered by anonymity in computer-mediated communication, I argue that: First, anonymity is popularly viewed as creating negative results for society at large, as expressed in public opinion of 2ch in general. However, anonymity can also be portrayed as having positive results for individuals, for example in the Densha Otoko narrative specifically. Secondly, anonymity on 2channel – in conjunction with other infrastructural aspects – facilitates ‘individual’ expression and creates a locus for freedom of speech via the elimination of personal identification. Finally, anonymity, in this case study, engenders sociality by drawing on notions of security and privacy.

description: Η παρούσα ερευνητική εργασία αποτέλεσε μιαν αρχική αποτύπωση της παρούσας κατάστασης σε σχέση με τους ψυχοκοινωνικούς κινδύνους στον επαγγελματικό χώρο των ελληνικών αστικών συγκοινωνιών. Βασικοί στόχοι ήταν η διερεύνηση της αντίληψης των Ψυχοκοινωνικών Κινδύνων Εργασίας (ΨΚΕ) και των πολιτικών διαχείρισής τους εκ μέρους των εμπλεκόμενων ατόμων ευθύνης εντός των οργανισμών που εκτελούν αστικές συγκοινωνίες. Στην έρευνα συμμετείχαν επτά συμμετέχοντες, οι οποίοι επιλέχθηκαν με σκόπιμη δειγματοληψία, λόγω της θέσης/ρόλου ευθύνης που κατείχαν στον οργανισμό τους. Ακολουθήθηκε ποιοτική μέθοδος και τα δεδομένα αναλύθηκαν θεματικά. Στα ευρήματα περιλαμβάνονται οι θεωρούμενοι επικρατέστεροι ΨΚΕ για το επάγγελμα του οδηγού. Επισημαίνεται ταυτοχρόνως ότι για κάποιους από αυτούς τους κινδύνους η εκδήλωση και ο τρόπος επίδρασής τους διαφοροποιούνται ουσιωδώς ανά εργασιακό πλαίσιο. Αναδείχθηκε ειδικότερα το ζήτημα της βίας και παρενόχλησης στην εργασία, το οποίο ερμηνεύεται και ως ξεχωριστός ΨΚΕ και ως αποτέλεσμα των υπαρχόντων ΨΚΕ. Η εργασία συζητά επίσης τη μέχρι τώρα εφαρμογή πρόσφατων νομικών διατάξεων από τους οργανισμούς αστικών συγκοινωνιών σε σχέση με την πρόληψη και αντιμετώπιση των ΨΚΕ. Τhis research project was an initial recording of the present situation in the professional field of Greek urban transport in relation to the workplace psychosocial risk factors. The aim was to investigate the perception of workplace psychosocial risks and the respective management policies by key stakeholders within urban transport organizations. There were seven participants who were selected through purposeful sampling based on their role/position within their organization. A qualitative method was used, and thematic analysis was implemented. The findings include the most prevalent perceived psychosocial risks for drivers. For some of them, their manifestation and impact are differentiated depending on workplace. Workplace violence and harassment were especially highlighted. This was interpreted both as an independent psychosocial risk and as an outcome of other existing psychosocial risks. The paper also discusses the extent to which the recent legal framework on psychosocial risk management has been implemented by the Greek urban transport organizations.

Formal and informal approaches to adjusting for exposure mismeasurement
Creators: name: Shen, Tian
Publisher: name: University of British Columbia
Year: 2009

description: In many research areas, measurement error frequently occurs when investigators are trying to analyze the relationship between exposure variables and response variable in observational studies. Severe problems can be caused by the mismeasured exposure vari ables, such as loss of power, biased estimators, and misleading conclusions. As the idea of measurement error is adopted by more and more researchers, how to adjust for such error becomes an interesting point to study. Two big barriers in solving the problems are as follows. First, the mechanism of measurement error (the existence and magnitude of the error) is always unknown to researchers. Sometimes only a small piece of information is available from previous studies. Moreover, the situation can be worsen when the study conditions are changed in the present study, which makes previous information not applicable. Second, some researchers may still argue about the consequences of ignoring measurement error due to its uncertainness. Thus, the adjustment for the mismeasurement turn to be a difficult, or impossible task. In this thesis, we are studying situations where the binary response variable is precisely measured, but with a misclassified binary exposure or a mismeasured continuous exposure. We propose formal approaches to estimate unknown parameters under the non-differential assumption in both exposure conditions. The uncertain variance of measurement error in the continuous exposure case, or the probabilities of misclassification in the binary exposure case, are incorporated by our approaches. Then the posterior models are estimated via simulations generated by the Gibbs sampler and the Metropolis - Hasting algorithm. Meanwhile, we compare our formal approach with the informal or naive approach in both continuous and exposure cases based on simulated datasets. Odds ratios on log scales are used in comparisons of formal and informal approaches when the exposure variable is binary or continuous. General speaking, our formal approaches result in bet ter point estimators and less variability in estimation. Moreover, the 95% credible, or confidence intervals are able to capture the true values more than 90% of the time. At the very end, we apply our ideas on the QRS dataset to seek consistent conclu sions draws from simulated datasets and real world datasets, and we are able to claim that overall our formal approaches do a better job regardless of the type of the exposure variable.

description: Food borne diseases are one of the major causes of morbidity and mortality all around the world. Foodborne disease can be defined as "any disease usually either infectious or toxic in nature, caused by agents that enter the body through ingestion of food" (Adams and Moss, 2003). Food borne diseases due to consumption of various animal products, viz. fish, milk, meat and eggs have remained a major topic of veterinary public health research. Various factors such as pathogen evolution, changes in agricultural and food manufacturing practices, changes in the host immune status and environmental changes etc., are contributing to the emergence and re-emergence of food borne pathogens and illnesses. The globalization of food trade has increased the risk of spreading foodborne hazards around the world.

description: This study aimed at documenting how young women and young men manage accountability concerns in the context of discussing women’s bodily/beauty practices. For the purposes of the study four focus group discussions (two of which involved young women and two involved young men) were conducted. Adopting the methodological tools of critical discursive social psychology, analysis indicated that all the participants were oriented towards the widely used dilemma of conformity vs. choice. It also showed differences in the way this central dilemma was managed by female and male participants. Specifically, male participants managed the dilemma, either by constructing the image of the woman who is an exception to the rule or by representing certain bodily/beauty practices as gender neutral. Female participants, on the other hand, although they underscored the patriarchal prescriptions of femininity, they portrayed themselves as possessing a ‘feminist consciousness,’ which protects them from becoming blind victims of societal pressures.

description: The study examined the relationship between gratitude and life satisfaction in educated adults in a non-Western context and the mediation of positive and negative affect. The sample comprised 711 males and females. They completed the Gratitude Questionnaire-6, the Satisfaction with Life Scale, and the Positive and Negative Affect Schedule. Structural Equational Modelling (SEM) analysis was used for testing the mediation hypothesis and multi-group analysis for testing gender differences. SEM showed a good fit for the hypothesised model of the study. Both positive and negative affect significantly mediated the relationship between gratitude and life satisfaction. There were no significant gender differences in gratitude and life satisfaction, but females significantly scored higher on negative affect, and males scored higher on positive affect, however, the multi-group confirmatory factor analysis failed to show significant gender differences.

Year: 2023
Subjects: Feminism; Foucauldian discourse analysis; Patriarchy; Spoken sexism

description: Spoken sexism is a heavily understudied phenomenon that perpetuates misogyny and sex-based discrimination while steadily reinforcing the patriarchy. The present paper aimed to explore how men discursively construct spoken sexism as a subject of debate, drawing upon a discourse of hegemonic masculinity, while sculpting for themselves a subject position of entitlement. The study was of qualitative nature. Twenty men took part voluntarily in individual semi-structured interviews. For the analyses of the material, post-structuralism was upheld as epistemological position while a Foucauldian discourse analysis (FDA) was used for the portrayal of the discourses. The gendered nature of the subject under discussion and the acknowledgement that spoken sexism is discursively constructed within patriarchal structures of power, led to a feminist perspective regarding the interpretation and discussion of the results. The findings revealed not only the resilience that characterizes female oppression but also provide a new understanding of how men shape in their discourse sexist comments in a beneficial way to further support their male privileges.

description: The $E_6$SSM extension of the MSSM allows for the solution of many of the difficulties that are usually encountered within conventional SUSY breaking scenarios, e.g., the $μ$ problem, the imposition of R-parity 'by hand', the generation of light neutrino masses and obtaining a light Higgs boson with a mass as large as $\sim$ 125 GeV as suggested by recent LHC measurements. In addressing these problems, such a scenario predicts the existence of additional singlet and vector-like superfields beyond those in the MSSM as well as possibly two new neutral gauge bosons near the TeV scale. In this paper the phenomenological implications of simultaneous gauge kinetic mixing between the usual Standard Model (SM) hypercharge gauge field and both these new neutral gauge fields present in the $E_6$SSM scenario is explored. To this end a large class of specific toy models realizing this type of kinetic mixing is examined. In particular, we demonstrate that a significant suppression (or enhancement) of the expected event rate for $Z'$ production in the dilepton channel at the LHC is not likely to occur in this scenario due to gauge kinetic mixing.

description: We investigate how strong a hypothetical 1S0 bound state of two neutrons would affect different observables in the neutron-deuteron reactions. To that aim we extend our momentum space scheme of solving three-nucleon Faddeev equations to incorporate in addition to the deuteron also the 1S0 dineutron bound state. We discuss effects induced by dineutron on the angular distribution of the neutron-deuteron elastic scattering and cross sections of the deuteron breakup. A comparison to the available data for neutron-deuteron total cross sections and elastic scattering angular distributions cannot decisively exclude a possibility that the two neutrons can form 1S0 bound state. However, the strong modifications of a final-state-interaction peak of the neutron-deuteron breakup when changing from negative to positive values of the neutron-neutron scattering length seems to exclude existence of dineutron.

To obtain the matter curves and the Yukawa couplings, we use a global description to resolve the singularity. We identify the vector and spinor matter representations and their Yukawa couplings and we explicitly build the G-fluxes in the global model and check the agreement with the semi-local results. As our bundle is of type SU(2k), some extra conditions need to be applied to match the fluxes.

The linear complex-valued eikonal components are introduced to describe the influence of the spin-orbit interaction and the deformation of a polarized Gaussian beam on the propagation firstly in this paper. In an inhomogeneous medium, the interaction between the polarization and the rotation deformation of the light beam is presented besides the spin-orbit interaction, it corresponds to the spin-intrinsic orbital angular momentum interaction and makes the correction for the spin Hall effect of a polarized Gaussian light beam.

description: Quantum information processing relies on precise control of non-classical states in the presence of many uncontrolled environmental degrees of freedom -- requiring careful orchestration of how the relevant degrees of freedom interact with that environment. These interactions are often viewed as detrimental, as they dissipate energy and decohere quantum states. Nonetheless, when controlled, dissipation is an essential tool for manipulating quantum information: Dissipation engineering enables quantum measurement, quantum state preparation, and quantum state stabilization. The progress of quantum device technology, marked by improvements of characteristic coherence times and extensible architectures for quantum control, has coincided with the development of such dissipation engineering tools which interface quantum and classical degrees of freedom. This Review presents dissipation as a fundamental aspect of the measurement and control of quantum devices and highlights the role of dissipation engineering for quantum error correction and quantum simulation that enables quantum information processing on a practical scale.

description: In this article, we have proposed a generalized Lucas matrix (recursive matrix of higher order) having relation with generalized Fibonacci sequences and established many special properties in addition to that usual matrix algebra. Further, we have proposed a modified public key cryptography using these matrices as keys in Affine cipher and key agreement for encryption-decryption with the combination of terms of generalized Lucas sequences under residue operations. In this scheme, instead of exchanging the whole key matrix, only a pair of numbers(parameters) need to be exchanged, which reduces the time complexity as well as space complexity of the key transmission and has a large key-space.

description: Context. We investigate the stellar population and the origin of diffuse light around brightest cluster galaxies. Aims. We study the stellar population of the dynamically hot stellar halo of NGC 3311, the brightest galaxy in the Hydra I cluster, and that of photometric substructures in the diffuse light to constrain the origin of these components. Methods. We analyze absorption lines in medium-resolution, long-slit spectra in the wavelength range 4800-5800 angstrom obtained with FORS2 at the Very Large Telescope. We measure the equivalent width of Lick indices out to 20 kpc from the center of NGC 3311 and fit them with stellar population models that account for the [alpha/Fe] overabundance. Results. Stars in the dynamically hot halo of NGC 3311 are old (age > 13 Gyr), metal-poor ([Z/H] ~ -0.35), and alpha-enhanced ([alpha/Fe] ~ 0.48). Together with the high velocity dispersion, these measurements indicate that the stars in the halo were accreted from the outskirts of other early-type galaxies, with a possible contribution from dwarf galaxies. We identify a region in the halo of NGC 3311 associated with a photometric substructure where the stellar population is even more metal-poor ([Z/H] ~ -0.73). In this region, our measurements are consistent with a composite stellar population superposed along the line of sight, consisting of stars from the dynamically hot halo of NGC 3311 and stars stripped from dwarf galaxies. The latter component contributes < 28% to the local surface brightness. Conclusions. The build-up of diffuse light around NGC 3311 is on-going. Based on the observed stellar population properties, the dominant part of these stars may have come from the outskirts of bright early-type galaxies, while stars from stripped dwarf galaxies are presently being added.

Multitemporal remote sensing of landscape pattern dynamics resulting from mountain pine beetle infestation and timber harvest
Creators: name: Gillanders, Steve Neil
Publisher: name: University of British Columbia
Year: 2009

description: Occurring over multiple years and impacting an area over 13 million hectares to date, the current epidemic of mountain pine beetle (Dendroctonus ponderosae Hopkins) in British Columbia lends itself to the use of remote sensing technologies for monitoring purposes. Change detection procedures based upon spectral values are common; however, monitoring changes in landscape pattern presents opportunities for the generation of unique and ecologically important information. Furthermore, while the use of two images may provide the means to identify change, the use of more than two images affords the ability for long-term monitoring and characterization of processes such as change rates and dynamics. The initial component of this study consists of a literature review undertaken to investigate and summarize methods and applications of landscape pattern analysis using three or more image dates. This information was in turn used to make recommendations for the application of landscape pattern analysis of a time-series of remotely-sensed data to a case study involving mountain pine beetle infestation and timber harvesting. Following the review, we focused on the detection and monitoring of lodgepole pine stands in order to quantify the progression of forest fragmentation and loss of connectivity as a result of mountain pine beetle infestation and timber harvest. This was accomplished using a key set of landscape pattern indices applied to six Landsat satellite images spanning 1993 to 2006. Through our analysis we found that the impacts of the mountain pine beetle on forest spatial pattern consist of an increase in the number of forest patches, shape complexity, and patch isolation, and a decrease in forest patch size and interspersion. In addition, we determined that in a spatial context, mountain pine beetle infestation plays a significantly greater role in forest fragmentation and loss of connectivity than timber harvest. However, we also discuss the limitations of these findings due to the differences between natural and anthropogenic disturbances and the inability of Landsat data to detect patch-level dynamics. This research demonstrates the unique information available from satellite image time-series combined with landscape pattern analysis to better understand the combined effects of insect infestation and forest harvesting.

description: We derive a Hamiltonian for the external and internal dynamics of an electromagnetically bound, charged two-particle system in external electromagnetic and gravitational fields, including leading-order relativistic corrections. We apply this Hamiltonian to describe the relativistic coupling of the external and internal dynamics of cold ions in Paul traps, including the effects of micromotion, excess micromotion, and trap imperfections. This provides a systematic and fully quantum-mechanical treatment of relativistic frequency shifts in atomic clocks based on single trapped ions. Our approach reproduces well-known formulas for the second-order Doppler shift for thermal states, which were previously derived on the basis of semiclassical arguments. We complement and clarify recent discussions in the literature on the role of time dilation and mass defect in ion clocks.

description: Bisphenol A (BPA), as an environmental endocrine disruptor can cause damage to the reproductive, nervous and immune systems. Laccase can be used to degrade BPA. However, laccase is easily deactivated, especially in organic solvents, but the specific details are not clear. Molecular dynamics simulations were used to investigate the reasons for changes in laccase activity in acetonitrile (ACN) and dimethyl formamide (DMF) solutions. In addition, the effects of ACN and DMF on the activity of laccase and surfactant rhamnolipid (RL) on the degradation of BPA by laccase were investigated. Results showed that addition of ACN changed the structure of the laccase, not only decreasing the van der Waals interaction that promoted the binding of laccase with BPA, but also increasing the polar solvation free energy that hindered the binding of laccase with BPA, so it weakened the laccase activity. DMF greatly enhanced the van der Waals interaction between laccase and BPA, and played a positive role in their binding. The addition of surfactant RL alleviated the effect of organic solvent on the activity of laccase by changing the polar solvation energy. The mechanism of surfactant RL affecting laccase activity in ACN and DMF is described, providing support for understanding the effect of organic solvents on laccase.

description: In this work we give a mechanical (Hamiltonian) interpretation of the so called spectrality property introduced by Sklyanin and Kuznetsov in the context of Bäcklund transformations (BTs) for finite dimensional integrable systems. The property turns out to be deeply connected with the Hamilton-Jacobi separation of variables and can lead to the explicit integration of the underlying model through the expression of the BTs. Once such construction is given, it is shown, in a simple example, that it is possible to interpret the Baxter Q operator defining the quantum BTs us the Green's function, or propagator, of the time dependent Schrödinger equation for the interpolating Hamiltonian.

Helping Users Help Themselves - Maximising Libanswers Usage
Creators: name: Hsien, Aaron
Publisher: name: Zenodo
Year: 2013

description: Frequently Asked Questions (FAQs) are a commonly seen feature on library websites. Most
libraries provide a short list of FAQs on static HTML pages while others employ full-blown
knowledge base systems that list the answers to hundreds of questions. In Aug 2010, the
National University of Singapore (NUS) Libraries began using Springshare’s LibGuides. At the
same time, we also moved from a static HTML list of FAQs to Springshare’s LibAnswers
platform - a database driven knowledge base system enriched with Web 2.0 features.
LibAnswers is a stand-alone but related module to LibGuides. It acts as a tool to allow students
to e-mail or text questions to a librarian. LibAnswers tracks and organizes these questions. A
librarian can then answer a question and add it to the knowledge base which is accessible
through a widget which can be placed on a LibGuide or on a static HTML page. As an added
benefit, LibAnswers has a reporting component which allows questions to be tracked and
reported.

description: In a recent article a generalization of the binomial distribution associated with a sequence of positive numbers was examined. The analysis of the nonnegativeness of the formal expressions was a key-point to allow to give them a statistical interpretation in terms of probabilities. In this article we present an approach based on generating functions that solves the previous difficulties: the constraints of nonnegativeness are automatically fulfilled, a complete characterization in terms of generating functions is given and a large number of analytical examples becomes available.

description: The MET signalling pathway regulates fundamental cellular processes such as growth, division, and survival. While essential for normal cell function, dysregulation of this pathway can contribute to cancer by triggering uncontrolled proliferation and metastasis. Targeting MET activity holds promise as an effective strategy for cancer therapy. Among potential sources of anti-cancer agents, marine organisms have gained attention. In this study, we screened 47,450 natural compounds derived from marine sources within the CMNPD database against the Met crystal structure. By employing HTVS, SP, and XP docking modes, we identified three compounds (CMNPD17595, CMNPD14026, and CMNPD19696) that outperformed a reference molecule in binding affinity to the Met structure. These compounds demonstrated desirable ADME properties. Molecular Dynamics (MD) simulations for 200 ns confirmed the stability of their interactions with Met. Our findings highlight CMNPD17595, CMNPD14026, and CMNPD19696 as potential inhibitors against Met-dependent cancers. Additionally, these compounds offer new avenues for drug development, leveraging their inhibitory effects on Met to combat carcinogenesis.
