description: Identification of brain regions related to the specific neurological disorders are of great importance for biomarker and diagnostic studies. In this paper, we propose an interpretable Graph Convolutional Network (GCN) framework for the identification and classification of Alzheimer's disease (AD) using multi-modality brain imaging data. Specifically, we extended the Gradient Class Activation Mapping (Grad-CAM) technique to quantify the most discriminative features identified by GCN from brain connectivity patterns. We then utilized them to find signature regions of interest (ROIs) by detecting the difference of features between regions in healthy control (HC), mild cognitive impairment (MCI), and AD groups. We conducted the experiments on the ADNI database with imaging data from three modalities, including VBM-MRI, FDG-PET, and AV45-PET, and showed that the ROI features learned by our method were effective for enhancing the performances of both clinical score prediction and disease status identification. It also successfully identified biomarkers associated with AD and MCI.

description: In Oaxaca, México, Haplophyton cimicidum is used in combination with other plants as part of a folk strategy against arthropod pests of crops and cattle. Methanolic and crude alkaloid (acid–base extraction) extracts of H. cimicidum leaves were analysed by thin-layer chromatography (TLC) and assayed in vitro for acetylcholinesterase (AChE) inhibitory activity using Spodoptera frugiperda homogenates as source of enzyme. Derivatised chromatographic plates indicated the presence of indoles and alkaloids in the extracts. The crude alkaloid extract exhibited a higher number of compounds than the methanolic extract as judged by the number of spots on TLC plates. The crude alkaloid extract had a weak inhibition potential of AChE with a lower IC50 (93 μg mL− 1) than the methanolic extract (159 μg mL− 1). Indole alkaloids may be responsible for the activity, though a subsequent analysis of the extract components is necessary to determine the active alkaloid(s).

description: In recent years, phishing scams have become the most serious type of crime involved in Ethereum, the second-largest blockchain platform. The existing phishing scams detection technology on Ethereum mostly uses traditional machine learning or network representation learning to mine the key information from the transaction network to identify phishing addresses. However, these methods adopt the last transaction record or even completely ignore these records, and only manual-designed features are taken for the node representation. In this paper, we propose a Temporal Transaction Aggregation Graph Network (TTAGN) to enhance phishing scams detection performance on Ethereum. Specifically, in the temporal edges representation module, we model the temporal relationship of historical transaction records between nodes to construct the edge representation of the Ethereum transaction network. Moreover, the edge representations around the node are aggregated to fuse topological interactive relationships into its representation, also named as trading features, in the edge2node module. We further combine trading features with common statistical and structural features obtained by graph neural networks to identify phishing addresses. Evaluated on real-world Ethereum phishing scams datasets, our TTAGN (92.8% AUC, and 81.6% F1score) outperforms the state-of-the-art methods, and the effectiveness of temporal edges representation and edge2node module is also demonstrated.

Techno-Economic Investigation of Street Furniture Usage for Outdoor Small Cell Planning: The Case of Addis Ababa, Ethiopia
Creators: name: Addis, Ebba

Year: 2020

description: For more than a decade, mobile network data traffic and users' demand are considerably increased due to the advent of evolving mobile technologies, capable end-user devices and data-intensive content. Different forecasts show that the growth will continue for similar reasons. To accommodate the increasing network traffic and users' demand, operators should continuously expand the capacity of their mobile networks using different capacity enhancing technologies. Network densification using small cells is one of the important capacity enhancement methods that are being implemented. To successfully exploit capacity benefits of network densification, efficient network planning is needed to address its deployment challenges including availability and cost of site, energy source and backhaul while minimizing interference and maximizing network capacity and users' throughputs. Using street furniture including lamp posts and utility poles during the planning of dense/ultra-dense networks is being considered as one method to address the availability of sites and cost challenges. But technoeconomic benefits of using the furniture and usage methods are not studied in the context of Addis Ababa. In this thesis work, the techno-economic benefits of using the furniture from an outdoor network planning perspective for a selected area of Addis Ababa will be investigated. The outdoor planning optimization is performed using technical and economic objectives while considering lamp posts and utility poles of the selected areas as part of candidate locations for small cells. The multiobjective optimization is solved using Genetic algorithm and its implementation and result analysis are performed using MATLAB. Propagation computation for network simulation is undertaken using a deterministic dominant path model that is implemented within WinProp. Empirical economic analysis results show that using streetlamp posts and utility poles decreases deployment cost by 17% compared to using a new standalone pole (dedicated pole used for only small cell deployment). Furthermore, obtained Pareto optimal networks from outdoor planning simulation that considers 143 lamp posts and 81 utility poles as candidate cells provide 53 lamp posts and 43 utility poles. Thus, only 24% is consumed by street posts for 96 sites while for 13 sites using new standalone pole 57% of the total deployment cost is consumed.

description: Plants of the Amaryllidaceae family are known as producers of biologically active alkaloids. Besides these a variety of flavonoids, including flavones, chalcones and chromones, have been detected in the Amaryllidaceous plants. In this study, we have analysed 16 representatives of the family for the presence of isoflavonoids. The water/ethanolic extracts were analysed with HPLC-ESI-MS both without any pre-treatment and after immunoaffinity chromatography as a clean-up step. Four individual immunosorbents specific for biochanin A, daidzein and genistein were used. In addition, five enzyme-linked immunosorbent assays specific for the above-mentioned isoflavonoids and their derivatives have been used for the analysis of the extracts after fractionation by semi-preparative HPLC. Fifteen selected isoflavonoids were detected in the studied samples, and the amount of individual compounds ranged between ca. 0.8 and 400 ng/g of dry weight. This study extends the number of known isoflavonoid-producing families within the monocotyledonous plants.

description: Violence risk assessment in psychiatric institutions enables interventions to avoid violence incidents. Clinical notes written by practitioners and available in electronic health records are valuable resources capturing unique information, but are seldom used to their full potential. We explore conventional and deep machine learning methods to assess violence risk in psychiatric patients using practitioner notes. The performance of our best models is comparable to the currently used questionnaire-based method, with an area under the Receiver Operating Characteristic curve of approximately 0.8. We find that the deep-learning model BERTje performs worse than conventional machine learning methods. We also evaluate our data and our classifiers to understand the performance of our models better. This is particularly important for the applicability of evaluated classifiers to new data, and is also of great interest to practitioners, due to the increased availability of new data in electronic format.

Analyzing Impact of Segment Routing MPLS on QoS

description: Multiprotocol Label Switching ( MPLS) Segment Routing (SR), SR-MPLS in short, is an MPLS data plane-based source routing paradigm in which a sender of a packet is allowed to partially or completely specify the route the packet takes through the network by imposing stacked MPLS labels to the packet. SR-MPLS could be leveraged to realize a unified source routing mechanism across MPLS, IPv4 and IPv6 data planes by using an MPLS label stack as unified source routing instruction set while preserving backward compatibility with traditional MPLS networks. The Segment Routing is a promising Traffic Engineering (TE) model that provides end-to-end communications. SR can observably improve the network utilization and control the routing path flexibly by encoding route information into a list of segments, i.e., the Segment List (SL). The key feature of SR is that it adopts the source routing paradigm, which implies the routing path followed by a packet is determined and written to the packet header by the first switch of SR networks (called Ingress SR switch). The motivation of this thesis is to investigate and analyze the impact of implementing SRMPLS on Quality of Service (QoS). The impact on QoS parameters is analyzed by using two scenarios; Traditional Unified MPLS integrating four domains into single MPLS domain and Segment Routing over Unified MPLS integrating four domains into a single MPLS domain. Simulation tools such as EVE-NG, Ostinato, Cisco IPSLA technology are used to compare performances of the two scenarios. The analysis results show that in SR-MPLS throughput is improved on average by 32%, latency is improved by 24%, packet loss is improved by 20.4% and jitter is improved by 12.6% compared to Label Distribution Protocol (LDP) based Unified MPLS. From the results, one can understand that any service provider can benefit from deploying Unified SR-MPLS. Segment Routing is a new routing paradigm that provide a better end-to-end QoS guarantee, making traditional MPLS network more efficient and scalable.

description: The extraction studies and a one-step purification of the crude extract of Plumbago indica using silica-gel vacuum chromatography provided a plumbagin derivative-rich P. indica root extract (PPE). The PPE was standardised to contain total plumbagin derivatives not less than 13% w/w. Antibacterial activities of the standardised PPE and three naphthoquinones, plumbagin, elliptinone and 3,3′-biplumbagin, against Propionibacterium acnes, Staphylococcus aureus and Staphylococcus epidermidis were evaluated by using the microdilution assay. The bactericidal activities of the PPE against these bacteria were much stronger than those of elliptinone and 3,3′-biplumbagin and almost equal to those of plumbagin. Stability of the PPE was determined under various conditions through a period of four months. The PPE was stable over a period of four months when stored as a dried powder but only in a well-closed container protected from light under 4 ± 2°C.

description: “Cartografie Radicali: Attivismo, Esplorazioni Artistiche, Geofiction” è un saggio scritto da Lorenza Pignatti, critica di arte e docente di Fenomenologia dell’arte contemporanea che presenta, in poco più di 200 pagine, «esplorazioni indisciplinate e curiosità errante alla ricerca di un approdo nello studio della cartografia (…)» (p. 7). Il volume, edito da Meltemi per la collana Estetica e culture visuali, si interroga su quale sia lo spazio della creazione artistica al tempo della geolocalizzazione. L’autrice che nutre un interesse per la cultura visuale, apre un dialogo con le discipline di ambito geografico, artistico e umanistico per capire come la rivoluzione tecnologica digitale, dal terzo millennio in poi, abbia permesso a collettivi ed artisti di realizzare performance e installazioni che hanno nutrito la New Media Art e la Net Art. In particolare, grazie alla cartografia “radicale”, l'autrice sceglie una lente attraverso cui esplorare le implicazioni culturali e artistiche dell'ampio utilizzo di dati geospaziali nella vita quotidiana. I riferimenti teorici e metodologici di respiro geografico che costellano le pagine del libro, sono molto generali e provano ad imbastire una cornice epistemologica, per non addetti ai lavori, al fine di contestualizzare i tanti esempi descritti nelle pagine a seguire.

Publisher: name: National Academic Digital Repository of Ethiopia

description: Currently, telecom service providers are using Multi-Protocol Label Switching (MPLS) technology in their IP core network to provide Virtual Private Network (VPN) services to their customers. However, most of the current IP core network of service providers' network does not have dynamic centralize configuration, provisioning and management mechanism, and also the network is not scalable enough. These limitations are caused by the vertical integration of data and control plane on networking device. In addition, the IP core layers of a service provider networks have redundancy on their network architecture (e.g. ethiotelecom IP core layer has five layers), which causes delay in configuration, provisioning and management. Hence, this thesis work shows how SDN based VPN is better than the existing VPN of a service provider network by comparing two networks performance parameters namely throughput and latency. Therefore, the simulation environment is setup using Linux routers for existing network; and openvswitches for the Software Defined Network (SDN) network. Finally, the simulation results for both networks have been presented on the result and discussion section. Based on the results found, the SDN- VPN throughput is 22.2222% higher than the existing VPN, and also its latency is 70.4675% lower than the existing VPN one

description: Faced with the scale and surge of misinformation on social media, many platforms and fact-checking organizations have turned to algorithms for automating key parts of misinformation detection pipelines. While offering a promising solution to the challenge of scale, the ethical and societal risks associated with algorithmic misinformation detection are not well-understood. In this paper, we employ and extend upon the notion of informational justice to develop a framework for explicating issues of justice relating to representation, participation, distribution of benefits and burdens, and credibility in the misinformation detection pipeline. Drawing on the framework: (1) we show how injustices materialize for stakeholders across three algorithmic stages in the pipeline; (2) we suggest empirical measures for assessing these injustices; and (3) we identify potential sources of these harms. This framework should help researchers, policymakers, and practitioners reason about potential harms or risks associated with these algorithms and provide conceptual guidance for the design of algorithmic fairness audits in this domain.

It is proposed to employ linear explosive tubes for plasma generation and to measure an areal density in shock-compressed plasma of argon and xenon. The proposed experiments will provide valuable information on influence of strong interparticle interactions on thermodynamic properties of strongly coupled plasma. The density measurement will help the researchers to understand the nature of wall and wire precursors arising in the shock tubes.

description: Polyisoprenylated benzophenones represent a group of chemical compounds commonly identified in Clusiaceae species and are responsible for a large amount of biological activities. In this work, the vasorelaxant effect induced by garcinielliptone FC (GFC) isolated from Platonia insignis Mart. (Clusiaceae), a monotype species from Platonia genus, was investigated. GFC promoted an endothelium-independent vasorelaxation on phenylephrine (PHE, 10− 5 mol L− 1)-induced vasoconstriction, but not on KCl (80 mmol L− 1)-induced vasoconstriction, on rat superior mesenteric artery rings. In addition, a concentration-dependent decrease of PHE- or serotonin-induced cumulative concentration–response curves was observed for GFC, and a slight decrease of pD2 value on CaCl2-induced vasoconstriction. In a Ca2+-free medium, GFC interfered in calcium mobilisation from PHE (10− 5 mol L− 1)-sensitive intracellular stores. GFC-induced vasorelaxant effect is probably mediated by a dual effect on mobilisation of calcium intracellular stores and attenuation of transmembrane calcium influx.

description: Dibenzylbutyrolactone-type lignan glycosides (tracheloside and carthamoside), their aglycones (trachelogenin and carthamogenin) and feruloyl-serotonin isomers were determined in the fruits of Leuzea carthamoides by using LC–UV, LC–MS/MS and GC–MS techniques. The composition of the embryo and wall parts of the fruits was analysed before and after their hydrolysis. As a result of these studies, fruit part-specific accumulation of lignan glycosides and feruloyl-serotonins were confirmed, demonstrating that the embryo contains a high amount of lignan glycosides (tracheloside 32.9 mg/g, carthamoside 45.3 mg/g), while the wall part of the fruit accumulates feruloyl-serotonins (63.0 mg/g). Enzymatic hydrolysis of the embryo resulted in the quantitative transformation of lignan glycosides into their corresponding aglycones, allowing selective isolation of trachelogenin and carthamogenin. These aglycones were subjected to an antiproliferative study against the SW480 colon adenocarcinoma cell line. In this test, moderate activity of carthamogenin and a significant effect of trachelogenin were demonstrated in a concentration range of 22–185 μM.

Here work is presented on combining knowledge graph construction (e.g. information extraction) and refinement (e.g. link prediction) in end to end systems. The challenges of ongoing knowledge graph maintenance and the role of people in that process are reflected on. Finally, we look to need for a knowledge scientist in these processes.

description: La scelta di scrivere un manuale nel campo delle discipline geografiche rappresenta una sfida sempre ambiziosa. Alto è infatti il rischio di realizzare un lavoro inadatto, incompleto o condizionato da valutazioni soggettive criticabili in merito alla trattazione dei temi necessari afornire una competenza adeguatamente ampia ed esaustiva. La decisione poi di dedicare un manuale alla geografia delle imprese contiene in sé il rischio legato al tentativo di ricondurre a ragione dinamiche la cui evoluzione appare quantomai rapida e indefinibile, tanto da rendere per alcuni obsoleta la natura stessa della disciplina.

description: Chemical investigation of the mycelial extract of a mixed culture of two marine alga-derived fungal strains of the genus Aspergillus has yielded one new cyclotripeptide, psychrophilin E (1), the recently reported oxepin-containing alkaloids, protuboxepin A (2) and oxepinamide E (3), together with three other polyketide derivatives (4–6). The chemical structure and relative and absolute configurations of psychrophilin E (1) were unambiguously established based on HRMS, 1D, 2D NMR and chiral-phase HPLC analysis of its hydrolysate. All the isolated compounds were assessed for their anti-proliferative activity against four different human cancer cell lines and some of them revealed selective activities.

description: Dibenzylbutyrolactone-type lignan glycosides (tracheloside and carthamoside), their aglycones (trachelogenin and carthamogenin) and feruloyl-serotonin isomers were determined in the fruits of Leuzea carthamoides by using LC–UV, LC–MS/MS and GC–MS techniques. The composition of the embryo and wall parts of the fruits was analysed before and after their hydrolysis. As a result of these studies, fruit part-specific accumulation of lignan glycosides and feruloyl-serotonins were confirmed, demonstrating that the embryo contains a high amount of lignan glycosides (tracheloside 32.9 mg/g, carthamoside 45.3 mg/g), while the wall part of the fruit accumulates feruloyl-serotonins (63.0 mg/g). Enzymatic hydrolysis of the embryo resulted in the quantitative transformation of lignan glycosides into their corresponding aglycones, allowing selective isolation of trachelogenin and carthamogenin. These aglycones were subjected to an antiproliferative study against the SW480 colon adenocarcinoma cell line. In this test, moderate activity of carthamogenin and a significant effect of trachelogenin were demonstrated in a concentration range of 22–185 μM.

description: Direct marketing is a form of communicating an offer directly to a targeted group of customers through a variety of media. It plays a major role in customer retention and service provisioning tasks. Retaining customers by providing products and services that meet their need is one of the main objectives of customer relationship management. Identifying prospective customers for direct marketing enables a company to reach specific audiences which will more effectively respond to promotions. Moreover, direct marketing helps businesses to optimize their marketing budget, keeps current customers loyal to them, and makes businesses capable of measuring the result obtained from promotions. Ethio telecom promotes service packages to its customers through SMS and mass communication channels. However, promotions should target customers based on the specific services they use, and customer over-touching should be reduced especially during SMS advertisement. In the current practice, no scientific methodology is implemented to estimate the potential respondents to cross-selling market promotion. Promotions are communicated to both potential buyers and non-buyers without distinguishing the two groups. Direct marketing approaches help the company to effectively allocate resources and give services based on the interests of customers. The aim of this thesis is to identify prospective customers in ethio telecom mobile valueadded service market. To achieve this goal, five classifiers namely Naive Bayes, Neural network, SVM, K-nearest neighbour, and Decision tree (J48) tested with customers service usage historical data. In this process, 900,000 customers' actual CDRs from ethio telecom were gathered and raw data aggregated with the aim of representing users' behaviour. The representation was based on users' responses towards service fee and time preference to use services. Sixteen feature variables and one predictor variable are constructed from the raw CDR collected. Data cleaning and class balancing done, and the selected classifiers tested for their accuracy in identifying prospective buyers of service packages. The right customers for direct marketing are identified and ways to minimize customer over-touching during the promotion of low-price packages are shown. So, beyond selecting a classifier with high accuracy, the study aims at maximizing correctly classified instances. Accordingly, except Naïve Bayes classifier, the other four classifiers resulted in better performance. with Neural network classifier more than 90% of voice and 93% of SMS packages potential buyers are identified. whereas Decision tree (J48) has scored the best result with data package buyers dataset by identifying more than 94% of potential buyers.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

Il primo libro di Geopolitica di Klaus Dodds

Publisher: name: Semestrale di studi e ricerche di geografia
Year: 2024

description: Il libro di Klaus Dodds si presenta come un manuale di base di geopolitica, con forti incursioni nel panorama della geopolitica critica. Uscito nel 2019 col titolo assai più efficace rispetto all’edizione italiana di Geopolitics: A Very Short Introduction, questo testo ha l’obiettivo di fornire i primi rudimenti – si suppone a studenti a inizio corso e appassionati – della geopolitica, nella sua parabola storica e nei riflessi internazionali e nella vita quotidiana. Per quale ragione il titolo in inglese è più efficace? Perché rende in maniera esplicita il senso dell’operazione culturale, del tentativo di dare una primissima e davvero breve introduzione all’ampio spetto dei concetti e dell’evoluzione della geopolitica e del suo pensiero. E invece, nella versione italiana si perde qualche pezzo: la traduzione non sempre risulta accurata, soprattutto per alcuni concetti propri del lessico geografico, così come i box di approfondimento non sempre appaiono ben posizionati all’interno del testo tanto da confondersi a tratti con esso.
