title: Junctional complexes and the control of platelet function
Creators: name: Alaajam, Fahd Mohammed M.
Publisher: name: University of Reading
Year: 2029

description: Background: Cell junctions form multiprotein complexes that facilitate contact or adhesion 
between neighbouring cells or between a cell and the extracellular matrix. Among these, gap 
junction-mediated intercellular communication has been found to regulate platelet function in 
an αIIbβ3-dependent manner. Notably, previous studies on JAM-A, a component of tight 
junctions, have reported clusters of JAM-A on thrombin-activated platelet contacts. JAM-A 
associates with integrin αIIbβ3 and suppresses its activation; however, this interaction is 
disrupted during platelet activation. Zonula occludens 2 (ZO-2) is another essential component 
of tight junctions, connecting the actin cytoskeleton with transmembrane components. 
Interestingly, approximately 3,900 copies of ZO-2 were detected in the platelet proteome. 
Additionally, significant levels of transcripts for zonula occludens proteins (ZO-1, ZO-2, and 
ZO-3) were found in megakaryocytes. Despite this, the protein expression or function of these 
ZO-proteins in platelets remains unknown. Therefore, our study aimed to explore potential ZO-containing complexes that mediate platelet functions.
Result: Immunoprecipitation and western blotting experiments confirmed the expression of 
ZO-1, ZO-2, and ZO-3 in human platelets. Both ZO-2 and JAM-A were found to form physical 
complexes in resting and thrombin-stimulated platelets. Confocal and super-resolution 
microscopy further confirmed complex formation, showing increased levels upon platelet 
stimulation as ZO-1 and ZO-2 translocated to the plasma membrane vicinity of both platelets 
and MEG-01 cells. Notably, the reduction of either ZO-1 or ZO-2 expression in MEG-01 cells 
using ZO-1 siRNA or ZO-2 siRNA hindered the disengagement of JAM-A from integrin 
αIIbβ3, which was associated with reduced fibrinogen binding. The role of ZO-1 in integrin 
αIIbβ3 regulation was further validated using the peptide inhibitor αCT1. Targeting ZO-1 with 
aCT1 in MEG-01 cells prevented JAM-A dissociation from integrin αIIbβ3, leading to reduced fibrinogen binding. The αCT1 peptide also diminished P-selectin exposure, platelet spreading, 
adhesion, and aggregation, highlighting its regulatory role in platelet function.
Conclusion: These findings suggest that ZO-1 and ZO-2 form a complex with JAM-A to mediate 
platelet activation. This new understanding of the molecular processes involved in platelet function 
suggests a promising new target for developing anti-thrombotic therapies.

description: El objetivo de la presente investigación fue identificar la relación existente entre las variables mobbing y bienestar psicológico en los 51 trabajadores de una institución educativa policial en la ciudad de Arequipa, en los meses de agosto a diciembre del año 2023. El nivel de la investigación es relacional y la técnica utilizada fue la del cuestionario. La variable mobbing fue medida utilizando la escala CISNEROS de Piñuel. Para la variable bienestar psicológico se utilizó la Escala de Felicidad de Lima de Reynaldo Alarcón. En cuanto a los resultados tenemos que del total de la población el 61.8% refiere no haber sufrido de acoso laboral, frente al 38.2% que afirma lo contrario; además, la forma más común de mobbing en las personas que refieren haberlo sufrido es de tipo vertical. En las dimensiones de mobbing se obtuvo que todas presentan un nivel muy bajo. En cuanto al bienestar psicológico se obtuvo un nivel alto y muy alto (27.5% cada uno), donde la mayoría de sus dimensiones se encuentra en un nivel promedio, exeptuando la dimensión “Alegría de vivir”, donde resalta el nivel muy alto (51%). Se concluye, mediante la aplicación de la prueba de chi cuadrado, que existe relación estadísticamente significativa de tipo inversa (x2=41.7, p=0,0004), entre las variables de mobbing y el bienestar psicológico.

Annual variability of nitrogen concentrations and export from forested catchments: A consequence of climatic variability, sampling strategies or human interference?
Creators: name: Andersson, L.

Publisher: name: Boreal Environment Research Publishing Board
Year: 2000

description: This study was based on the data from 18 years of monitoring in six forested catchments. The aim was to find links between annual estimates of export and concentrations of NO3-N and organic N and hydroclimatological factors, sampling strategy and human interference. A topography-based wetness index was used to assess whether the effects of forestry activities depended on prevailing wetness conditions. For organic N, annual runoff was the main explaining factor in three catchments. The flow condition during sampling was for organic N the main explaining factor in three and for NO3-N in one catchment. Effects of clear-cutting of 14% in one catchment were observed. For organic N, the model could be improved by considering clear-cutting in wet areas only. The southernmost catchment, but also the northernmost catchment with the lowest deposition, showed links to atmospheric deposition, demonstrating that deposition can cause a significant direct response in streamwater concentrations in nutrient-poor catchments.

Η προσέγγισή μας περιλαμβάνει την προσεκτική παρατήρηση και την τεκμηρίωση των επιχειρησιακών αναγκών, ακολουθούμενη από την προσεκτική επιλογή κατάλληλων λογισμικών αρχιτεκτονικών. Στη συνέχεια, μεταβαίνουμε στη φάση σχεδιασμού υψηλού επιπέδου, περιγράφοντας την καταγραφή της λύσης, και στη συνέχεια αναλύουμε στις λεπτομέρειες του σχεδιασμού τόσο της λύσης όσο και των συστατικών της. Η υλοποίηση και οι αυστηρές δοκιμές συμπληρώνουν τη μεθοδολογία μας. Ο κυρίαρχος στόχος μας ήταν η ανάπτυξη μιας εφαρμογής που θα λειτουργεί ως Υγειονομικός Βοηθός/Σχεδιαστής, έτοιμη να προσφέρει μια σειρά λειτουργιών που εξυπηρετούν την παρακολούθηση της υγείας, τις εξατομικευμένες προτάσεις και τις στρατηγικές διαχείρισης κόστους. Η λογική αρχιτεκτονική που έχουμε σχεδιάσει διαθέτει σύγχρονα χαρακτηριστικά που στοχεύουν στην απλοποίηση των διαδικασιών δοκιμής και αναπτύξεως, βελτιώνοντας έτσι την προσαρμοστικότητά της σε διάφορα περιβάλλοντα, ιδίως επιτρέποντας αναπτύξεις σε cloud. Εκμεταλλευόμενοι τεχνολογίες όπως το containerization και η απεικόνιση λειτουργικού συστήματος, έχουμε δημιουργήσει μια λύση που προσομοιάζει αποτελεσματικά τα απαιτούμενα περιβάλλοντα. Κεντρικό στη φιλοσοφία σχεδιασμού μας είναι η έμφαση στη φορητότητα και την απρόσκοπτη ανάπτυξη, επιτρέποντας τη χρήση της ως πίσω μέρος τόσο για συμβατικά όσο και για λογισμικά περιβάλλοντα. Tο containerization επιτρέπει στους προγραμματιστές να δημιουργούν και να αναπτύσσουν εφαρμογές πιο γρήγορα και με μεγαλύτερη ασφάλεια.

description: Η εκπόνηση της παρούσας διπλωματικής εργασίας στοχεύει στη βαθύτερη κατανόηση των ζητημάτων που φέρνει στο προσκήνιο η τεχνητή νοημοσύνη σε σχέση με τα νέα ψηφιακά συστήματα που μετασχηματίζουν όλο ένα και περισσότερο τον κόσμο των χρηματοπιστωτικών (τραπεζικών) ιδρυμάτων. Η νέα πραγματικότητα που διαμορφώνει η τεχνητή νοημοσύνη, θέτει τα θεμέλια για μία εναλλακτική λειτουργία των επιχειρήσεων, επιδρά άμεσα στο μετασχηματισμό των τραπεζικών δραστηριοτήτων, αναπτύσσει διάφορα εργαλεία τεχνητής νοημοσύνης και βελτιώνει την ποιότητα παροχής υπηρεσιών και την εξυπηρέτηση των πελατών. Για την υλοποίηση της έρευνας, αξιοποιήθηκαν δεδομένα από χρηματοπιστωτικούς οργανισμούς και άλλους επιστημονικούς κλάδους, συμπεριλαμβανομένων τραπεζών, θυγατρικών τους εταιρειών και ιδιωτικών εταιρειών με ενεργή παρουσία στην Ελληνική αλλά και Ευρωπαϊκή αγορά. Συνολικά, 140 ερωτηματολόγια διανεμήθηκαν ηλεκτρονικά, εκ των οποίων τα 67 συμπληρώθηκαν. Από το συνολικό δείγμα το όποιο συγκεντρώθηκε μπορεί κανείς να αντιληφθεί ποια τελικά είναι η σημασία της τεχνητής νοημοσύνης, πως αυτή ασκεί επιρροή αλλά και ποιοι κίνδυνοι ενδέχεται να παρουσιαστούν από την μη λελογισμένη χρήση της. Πιο συγκεκριμένα, και βάσει της ερευνητικής ανάλυσης που ακολουθεί, παρατίθενται απόψεις που αφορούν στον τρόπο ψηφιακής οργάνωσης και διαχείρισης των νέων τεχνολογιών στον τραπεζικό κλάδο. Από τις αποκρίσεις των ερωτηθέντων δίνεται μια αντιπροσωπευτική εικόνα για τη σημασία βελτιστοποίησης του τρόπου λειτουργίας των τραπεζών, επιτάχυνσης της διεκπεραίωσης των αιτημάτων, αύξησης της ικανοποίησης των πελατών, επέκτασης της πελατειακής βάσης και απλοποίησης των διαδικασιών. Ωστόσο, όπως παρατηρείται, ενδέχεται να προκύψουν προβληματισμοί και εμπόδια κατά την εφαρμογή των νέων συστημάτων, τα οποία θα πρέπει ληφθούν υπόψιν και να αξιολογηθούν με ιδιαίτερη προσοχή. Επιπλέον, η έρευνα επικεντρώνεται και στην ανάλυση του case study της HSBC, από την οποία διαπιστώνεται η πρακτική εφαρμογή των τεχνολογιών τεχνητής νοημοσύνης ως καταλύτη στη βελτίωση διαχείρισης κρίσεων, συμπεριλαμβανομένης και της πανδημίας COVID-19. Συμπληρωματικά, ψηφιακά βοηθήματα τεχνητής νοημοσύνης όπως τα smart contracts, θα αποτελέσουν κορωνίδα της προσπάθειας εκσυγχρονισμού λειτουργίας των χρηματοπιστωτικών μέσων. Αξίζει ακόμα να σημειωθεί, ότι βάσει άρθρων και επιστημονικών αναλύσεων, υποστηρίζονται επιστημονικά πλέον απόψεις και προβληματισμοί για τις νέες τεχνολογίες. Ωστόσο, αρκετοί είναι εκείνοι που τελικώς υποστηρίζουν ότι η εκμάθηση και η βαθύτερη ενασχόληση με τις νέες τεχνολογίες θα συμβάλλει καθοριστικά στην καλύτερη εξοικείωση και τελικά αξιοποίηση αυτών.

description: Digital data have become a valuable resource for autocratic governments seeking to influence societal behaviours. The rise of social credit systems in China has garnered a great deal of attention, with some even referring to them as ‘Orwellian’ surveillance systems. This study expands on previous research that has found surprisingly high levels of acceptance of social credit systems in China to the Southeast Asian region. Through an online opinion survey conducted in Thailand, Indonesia, Malaysia and the Philippines, we discovered that citizens in these countries exhibit higher acceptance rates of social credit systems than opposition rates, although lower than those observed in China. Moreover, we find that acceptance rates would decline significantly if the technologies supporting these systems originated from China. By introducing an external technology acceptance model, we provide an explanation for these findings based on citizens' attitudes towards their domestic situation and their perceptions of China's potential benefits to their countries. Interestingly, most of the ‘China Threat’ perceptions do not translate into opposition against Chinese social credit system technologies, except for military risks. Instead, citizens' negative views are primarily influenced by specific technology-related risks. These findings contribute to the existing literature on the acceptance of government-run social credit systems and public perception in the context of international relations.

description: Explainable Artificial Intelligence (XAI) is an area of AI that aims to make AI systems human-understandable by explaining their functions, knowledge and actions. However, it is difficult to define and quantify how well people actually understand machine explanations. This thesis investigates an operational approach to define and analyse the effects of machine explanations on human comprehension. We explore AI-human interactions where people are taught by AI. An AI ``teacher'' presents machine explanations and human ``students'' are evaluated on how accurately they can apply the taught knowledge on new materials. Notably, we show that explanations provided by AI can quantifiably boost human task performance and lead to the re-discovery of efficient computational algorithms by non-experts. We present an assessment framework $E_{ex}$ to empirically quantify 1) both the beneficial and harmful effects of machine explanations and 2) the impacts of machine-human teaching curricula. This framework can evaluate machine explanations regardless of their representations. To demonstrate this framework, we examine explanations generated from logic theories learned via a Machine Learning approach called Inductive Logic Programming (ILP). These logic theories are computational logic statements learned by ILP systems from training examples. We describe a preliminary theoretical work that characterises the properties of logic theories and curricula for enhancing human task performance. We show that learning from a machine-learned logic theory that is informatively compact and less cognitively demanding improves human task performance. We also observe that teaching by building on simpler concepts benefits human task performance. When concepts with increasing complexity are explained, human novices can develop efficient computational algorithms.

description: In this paper, we study the problem of scattering by several strictly convex obstacles, with smooth boundary and satisfying a non eclipse condition. We show, in dimension 2 only, the existence of a spectral gap for the meromorphic continuation of the Laplace operator outside the obstacles. The proof of this result relies on a reduction to an open hyperbolic quantum map, achieved in [arXiv:1105.3128]. In fact, we obtain a spectral gap for this type of objects, which also has applications in potential scattering. The second main ingredient of this article is a fractal uncertainty principle. We adapt the techniques of [arXiv:1906.08923] to apply this fractal uncertainty principle in our context.

description: Lake Peipsi on the border of Estonia and Russia is a large, shallow, biologically very productive lake. It is bordered by many wetland areas. On the basis of underwater radiation measurements and analyses of water samples we have shown that the optical properties of L. Peipsi are very variable both spatially and temporally, covering a large range of water types previously classified in Estonian and Finnish lakes. Inherent and apparent optical properties are compared with those of the two other large lakes, Vänern and Vättern in Sweden. Lake Peipsi has higher concentrations of optically active substances, which are known to influence satellite measurements and underwater light field. Therefore, the lake complements the continuum between L. Vänern and L. Vättern in terms of water optical properties and adds new data into the database about optical properties of turbid and humic lakes. Results obtained here can be used in bio-optical modeling to develop algorithms for remote sensing and calculations of underwater light field.

description: The burgeoning availability of sensing technology and location-based data is driving the expansion of analysis of human mobility networks in science and engineering research, as well as in epidemic forecasting and mitigation, urban planning, traffic engineering, emergency response, and business development. However, studies employ datasets provided by different location-based data providers, and the extent to which the human mobility measures and results obtained from different datasets are comparable is not known. To address this gap, in this study, we examined three prominent location-based data sources: Spectus, X-Mode, and Veraset to analyze human mobility networks across metropolitan areas at different scales: global, sub-structure, and microscopic. Dissimilar results were obtained from the three datasets, suggesting the sensitivity of network models and measures to datasets. This finding has important implications for building generalized theories of human mobility and urban dynamics based on different datasets. The findings also highlighted the need for ground-truthed human movement datasets to serve as the benchmark for testing the representativeness of human mobility datasets. Researchers and decision-makers across different fields of science and technology should recognize the sensitivity of human mobility results to dataset choice and develop procedures for ground-truthing the selected datasets in terms of representativeness of data points and transferability of results.

description: We show that if $G$ is a countable amenable group, then every stationary non-Gaussian symmetric $α$-stable (S$α$S) process indexed by $G$ is ergodic if and only if it is weakly-mixing, and it is ergodic if and only if its Rosinski minimal spectral representation is null. This extends the results for $\mathbb{Z}^d$, and answers a question of P. Roy on discrete nilpotent groups to the extent of all countable amenable groups. As a result we construct on the Heisenberg group and on many Abelian groups, for all $α$ in (0,2), stationary S$α$S processes that are weakly-mixing but not strongly-mixing.

Nanofabrication, measurement, and microscopy of ~10 nm scale single electron transistors

description: Room temperature (RT) point-contact (PC) single electron transistors (SETs) in silicon (Si) allow control of charge on a nanoscale quantum dot (QD) at the one electron level. These devices are of great interest for investigations of few particle physics and ‘beyond CMOS’ nanoelectronics applications. However, RT operation requires ultra-small sub-10 nm QDs, such that the single electron charging energy EC ≫ kBT = 26 meV, the thermal energy at RT, raising major nanofabrication challenges. This work considers the nanofabrication, electrical measurement, and non-invasive optical characterisation of ∼10 nm scale QD SETs. Devices were defined in silicon-on-insulator material with an n-type doped (1020 cm−3) ∼40 nm top Si layer using electron beam lithography and plasma etching. ‘Geometric oxidation’ of the PC region isolated dopant atom QDs. An alternative hybrid SET/Field Effect Transistor was also developed, with partially oxidised PCs. Fabrication process calibration greatly improved device success percentage to ∼37%, well above previous studies with ∼10%. Single electron simulation using an equivalent circuit model allowed extraction of QD parameters. Although fabrication process calibration reduces device failure, significant problems can persist at the ∼10 nm scales and structural inspection is critical. Conventional inspection methods, e.g., scanning electron microscopy, offer few-nm resolution but may be invasive and induce damage. Optical dark-field microscopy enables non-invasive, sub-wavelength investigation of nanostructures. Previously, this method was used to investigate ∼100 nm scale nanoelectromechanical systems and isolated, ∼10 nm scale nanoparticles. Here, we show for the first time that when applied to complete ∼10 nm scale SET structures, fabrication failure can be identified. Optical simulation, based on rigorous modal diffraction theory, was optimised to obtain a speed-up of ∼600× compared to previous reports. This enabled extraction of diffraction peak signatures for typical nanofabrication failures. Hence, comparison to experimental images created a method for non-invasive identification of successfully fabricated devices.

description: The purpose of this article is to analyse the content and importance of social impact assessment (SIA) in urban planning. SIA can be defined as a systematic effort to identify and analyse social impacts of a proposed project or plan on the individual, on social groups within a community, or on an entire community in advance of the decision-making process. Social impacts of urban plans refer to various factors such as quality of housing, local services and living environment, gentrification or segregation, conditions of transportation etc. The article is focusing on the Finnish experiences, which are representing pioneering work in this field in the whole world. In Finland the new Land Use and Building Act, which came into force on 1 Jan. 2000, brought impact assesment as an integral part of urban planning. The SIA experiences in Jyväskylä City offer an interesting case. In addition, the paper presents a typology of various factors (dimensions of impacts) for different scales of land-use plans. It is important to understand what kind of impact typologies are relevant in various scales of planning such as detail plans, general plans or regional plans.

description: Concentrations of dissolved greenhouse gases (GHGs) methane (CH4), carbon dioxide (CO2) and nitrous oxide (N2O) were investigated in a small southern boreal lake during the late winter ice-cover in 2000, 2001 and 2002. Potential emissions of these gases to the atmosphere at ice melt were estimated from their concentration profiles in the water column under ice during winter. The concentrations of CH4, CO2 and N2O increased with the depth, but the year-to-year variations were low. Carbon dioxide contributed to 99% of the global warming potential (GWP) of the total springtime GHG emissions which ranged from 103 to 128 g CO2-equivalents m–2. The results indicated that these kinds of northern mesotrophic lakes are not important sources of CH4 and N2O, but are probably significant sources of CO2.

Investigation of foam flow in porous media via physics-based modelling and numerical simulations
Creators: name: Zhang, Haosen
Publisher: name: Imperial College London
Year: 2023

description: Predicting foam dynamics in porous media poses significant challenges, primarily due to the multitude of gas-liquid interfaces within foam and their intricate interactions with confined structures. This study advances our understanding of foam physics by introducing novel foam modelling approaches and examining foam flow in representative scenarios. Three foam modelling methods are integrated and thoroughly investigated: the quasi-static soap film model, the viscous froth model, and the boundary integral method. The first method is conventionally employed to directly predict foam configurations in stationary equilibrium or in quasi-static motion, and in this thesis, it is extended to the pore-network scale. The research reveals that pressure differences between pore throats play a similar role in minimising overall surface energy as film tension does at the pore scale. The second approach pertains to the viscous froth model, originally designed for monolayer foams constrained in Hele-Shaw cells, and conventionally considered in two dimensions (2D). In this thesis, the 2D viscous froth model undergoes an extension into three dimensions (3D). This extension highlights the impact of the third dimension on foam behaviour, effectively connecting the quasi-static soap film model with the dynamic viscous froth model. Its application to a viscous froth lens in 3D reveals that the driving velocity-to-gap size ratio is a dominant factor in determining the motion of a viscous froth lens. Finally, a new method for modelling dry foam dynamics is developed based on the boundary integral method which considers the viscosity of gas, not just that of liquid, making it applicable to a broader range of foam flow rates. This method is utilised to investigate the typical problem of film motion in a diverging-converging channel, offering a new perspective on the emergence of yield stress. It is also implemented in 2D, connecting to the modelling of foam in Hele-Shaw cells.

description: Complicated Quaternary sediment strata have been preserved within the ice-divide zone of northern Finland because of weak glacial erosion. Geographic Information System (GIS) databases, 3D modelling and ground penetrating radar surveys were used to construct the 3D structure of unconsolidated sediments and bedrock topography for Kersilö, Sodankylä, to provide information for freshwater management and environmental studies in the mineral exploration area. The model was created using a combination of explicit and implicit modelling covering an area of 10.5 km2. The surficial deposits in the study area are a few metres thicker than their average thickness in northern Finland. They include three till units and four sandy or gravelly units. Fluvial action has repeatedly deposited sorted sediments in the channel valley of the Kitinen river. Basins in the bedrock have preserved thick sediment packages (> 15 m), indicating that the bedrock topography controls the sedimentary features. Aquifers in the area are small and disconnected, and perched aquifers exist due to the low hydraulic conductivity of interlayered tills.

description: In distributed computing, a Byzantine fault is a condition where a component behaves inconsistently, showing different symptoms to different components of the system. Consensus among the correct components can be reached by appropriately crafted communication protocols even in the presence of byzantine faults. Quantum-aided protocols built upon distributed entangled quantum states are worth considering, as they are more resilient than traditional ones. Based on earlier ideas, here we establish a parameter-dependent family of quantum-aided weak broadcast protocols. We compute upper bounds on the failure probability of the protocol, and define and illustrate a procedure that minimizes the quantum resource requirements. Following earlier work demonstrating the suitability of noisy intermediate scale quantum (NISQ) devices for the study of quantum networks, we experimentally create our resource quantum state on publicly available quantum computers. Our work highlights important engineering aspects of the future deployment of quantum communication protocols with multi-qubit entangled states.

Exploring the Meaning of Pidgin English on Social Media: A Sociolinguistic Analysis of Nigerian Pidgin Hashtags as Adapted Speech
Creators: name: Mosunmola, Oluyinka Adebayo
Publisher: name: Zenodo
Year: 2023

description: This study investigates the use of Pidginised English in social media, with a specific focus on Nigerian Pidgin hashtags. The significance of this study lies in its contribution to the knowledge and understanding of Nigerian Pidgin English hashtags on socialmedia. The findings expand our understanding of the sociolinguistic dynamics, cultural expressions, linguistic features, and communicative impact of Pidgin English in the digital era, thereby enriching our knowledge of language variation and communication practices in the online space.Forty Pidginised hashtags on social media constitute thedata, including surveys, and interviews. The study analyses the meanings of the hashtags within the Nigerian Pidgin context, the linguistic factors that necessitated their use, as well as the sociolinguistic and cultural implications of the use of Nigerian Pidginhashtags. The study adopts the Variationist Sociolinguistics theory to analyse the data. The findings suggest that pidginised English in social media is a reflection of linguistic diversity and cultural identity, but also serves as a means of social commentary and political critique. This study contributes to the understanding of language use in digital spaces and highlights the impacts of the use of hashtags on social media platforms to promote linguistic and cultural diversity.Keywords: adapted speech, hashtags, Nigerian Pidgin, sociolinguistics analysis, socialmedia
