Tor Network Website Fingerprinting Using Statistical-Based Feature and Ensemble Learning of Traffic Data

This paper proposes a website fingerprinting method using ensemble learning over a Tor network that guarantees client anonymity and personal information. We construct a training problem for website fingerprinting from the traffic packets collected in the Tor network, and compare the performance of the website fingerprinting system using tree-based ensemble models. A training feature vector is prepared from the general information, burst, cell sequence length, and cell order that are extracted from the traffic sequence, and the features of each website are represented with a fixed length. For experimental evaluation, we define four learning problems (Wang14, BW, CW T , CW H ) according to the use of website fingerprinting, and compare the performance with the support vector machine model using CUMUL feature vectors. In the experimental evaluation, the proposed statistical-based training feature representation is superior to the CUMUL feature representation except for the BW case.
Assessment of Nurses’ Workload in Intensive Care Unit by Use of Scoring Systems

Aim. To assess the level of correlation between two scoring systems: patient categorization according to the Croatian Nursing Council consensus and Nine Equivalents of Nursing Manpower Use Score (NEMS) and their ability to determine if the number of nurses working in the intensive care unit (ICU) is optimal to provide adequate nursing care, and to assess the level of correlation between the severity of patients’ illness and the level of nurses’ satisfaction with provided care. Methods. Research was performed in surgical ICU of the Clinical Department of Anesthesiology, Resuscitation and Intensive Care Medicine, University Hospital Dubrava, in the period between January 8th and April 14th, 2014. 256 patients aged 18-92 years were included in the study. Patient categorization and NEMS were calculated each day during the first 7 days of the ICU stay. NEMS was calculated using a pre-made table of variables and categorization was calculated using an electronic form included in nursing electronic patient files. Satisfaction of provided care was expressed using the Likert scale (1-5). Results. Study results have shown a moderate but significant level of correlation between the categorization and NEMS scores. Mean NEMS score during the first 7 days in the ICU was 26.93 ± 4.64 and the highest measured values were at day 4 (30.34±8.1) after which they started decreasing. Mean cumulative NEMS throughout the whole ICU stay was 269.3. According to the fact that according to NEMS scoring system one nurse can provide maximum of 45 points for 24 hours, the results have shown that a 10 bed ICU needs at least 5.98 (6) nurses to provide adequate level of care. Average categorization score was 57.83±4.29 and the highest recorded score was at day 7 (59.7±4.44). According to the categorization scoring system time needed to provide care for one 4th category patient throughout 24 hours is 10 or more hours. Since the description of the 4th category doesn’t specify what is the upper limit of time needed to provide care for each patient, 14 hours was used to determine a minimum number of nurses, and according to the categorization score 5.83 (6) nurses are needed in the ICU. Nurses’ satisfaction with provided care has shown a significant negative correlation with NEMS score and categorization score. Conclusion. Both scoring systems can be used to assess nursing workload in a surgical ICU. However, NEMS is simpler and quicker to use, more applicable, useful and should be routinely used in place of categorization to assess nursing workload in surgical ICUs.
Occurrence and Removal of Veterinary Antibiotics in Livestock Wastewater Treatment Plants, South Korea

In this study, livestock wastewater treatment plants in South Korea were monitored to determine the characteristics of influent and effluent wastewater, containing four types of veterinary antibiotics (sulfamethazine, sulfathiazole, chlortetracycline, oxytetracycline), and the removal efficiencies of different treatment processes. Chlortetracycline had the highest average influent concentration (483.7 μg/L), followed by sulfamethazine (251.2 μg/L), sulfathiazole (230.8 μg/L) and oxytetracycline (25.7 μg/L), at five livestock wastewater treatment plants. Sulfathiazole had the highest average effluent concentration (28.2 μg/L), followed by sulfamethazine (20.8 μg/L) and chlortetracycline (11.5 μg/L), while no oxytetracycline was detected. For veterinary antibiotics in the wastewater, a removal efficiency of at least 90% was observed with five types of treatment processes, including a bio-ceramic sequencing batch reactor, liquid-phase flotation, membrane bioreactor, bioreactor plus ultrafiltration (BIOSUF) and bio best bacillus systems. Moreover, this study evaluated the removal efficiency via laboratory-scale experiments on the conventional contaminants, such as organic matter, nitrogen, phosphorus and veterinary antibiotics. This was done using the hydraulic retention time (HRT), under three temporal conditions (14 h, 18 h, 27 h), using the anaerobic–anoxic–oxic (A2O) process, in an attempt to assess the combined livestock wastewater treatment process where the livestock wastewater is treated until certain levels of water quality are achieved, and then the effluent is discharged to nearby sewage treatment plants for further treatment. The removal efficiencies of veterinary antibiotics, especially oxytetracycline and chlortetracycline, were 86.5–88.8% and 87.9–90.8%, respectively, exhibiting no significant differences under various HRT conditions. The removal efficiency of sulfamethazine was at least 20% higher at HRT = 27 h than at HRT = 14 h, indicating that sulfamethazine was efficiently removed in the A2O process with increased HRT. This study is expected to promote a comprehensive understanding of the behavior and removal of veterinary antibiotics in the livestock wastewater treatment plants of South Korea.

Transfer learning and domain adaptation based on modeling of socio-economic systems

This article deals with the application of transfer learning methods and domain adaptation in a recurrent neural network based on the long short-term memory architecture (LSTM) to improve the efficiency of management decisions and state economic policy. Review of existing approaches in this area allows us to draw a conclusion about the need to solve a number of practical issues of improving the quality of predictive analytics for preparing forecasts of the development of socio-economic systems. In particular, in the context of applying machine learning algorithms, one of the problems is the limited number of marked data. The authors have implemented training of the original recurrent neural network on synthetic data obtained as a result of simulation, followed by transfer training and domain adaptation. To achieve this goal, a simulation model was developed by combining notations of system dynamics with agent-based modeling in the AnyLogic system, which allows us to investigate the influence of a combination of factors on the key parameters of the efficiency of the socio-economic system. The original LSTM training was realized with the help of TensorFlow, an open source software library for machine learning. The suggested approach makes it possible to expand the possibilities of complex application of simulation methods for building a neural network in order to justify the parameters of the development of the socio-economic system and allows us to get information about its future state.
Mobilizing memories: The social conditions of the long-term impact of victimization

Recent research has focused on the legacies of civil war violence on political preferences, finding that wartime victimization decreases support for the perpetrator or its political identity in the long run. However, we know little about the conditions under which this effect takes place. Historical accounts from civil wars suggest that the long-term effect of violence is not homogenous, nor consistent across areas within a single conflict. Addressing this gap, this article explores the effects of wartime victimization on long-term political preferences at the local level, looking at the conditioning effect of the local social context. In particular, I argue that the effect of wartime violence depends on the existence of local networks that create and maintain memories of the violence and capitalize on them for future mobilization. This argument is tested in the context of the Spanish Civil War. I build a novel dataset using archival data, historical secondary sources, and already existing datasets, covering 2,100 municipalities across Spain. In line with the argument, it is found that Francoist wartime victimization during the civil war is linked to an increase in leftist vote share after democracy was restored four decades later, but mainly in those municipalities where clandestine, left-leaning political networks were active after the conflict.
Appliquer un procédé argumentaire pour revendiquer une attribution des services en ergothérapie basée sur l’habilitation aux occupations

Problematique : L’attribution actuelle des services en ergotherapie en CLSC permet difficilement aux ergotherapeutes d’intervenir selon leur expertise premiere d’habilitation aux occupations. Pour revendiquer cette situation, les professionnels sont appeles a agir comme agent de changement et idealement avoir recours a un procede argumentaire. Objectif : Appliquer un procede argumentaire a une situation professionnelle problematique en ergotherapie, soit revendiquer une attribution des services en ergotherapie en CLSC basee sur l’habilitation aux occupations. Methode : Le procede argumentaire est base sur le cadre argumentaire Convictions-Reel-Actions-Fondements (CRAF) necessitant une recherche d’arguments provenant d’une recension critique des ecrits. Resultats : Les etudes recensees font valoir des arguments bases sur les valeurs et les fondements theoriques de la profession. Les arguments issus des resultats probants proviennent d’etudes dont le niveau d’evidence scientifique est eleve. Ils montrent que des interventions basees sur l’habilitation aux occupations ont des retombees sur la participation et le fonctionnement dans les occupations, le bien-etre et la sante physique et mentale, la perception d’efficacite personnelle, la satisfaction de vie, les interactions sociales, l’apprentissage de connaissances et l’esperance de vie. Discussion : L’habilitation aux occupations dans une approche de prevention et de promotion de la sante est efficace et rentable, et ce, pour une clientele plus vaste que celle actuellement desservie. Les ergotherapeutes, desireux d’etre agent de changement dans leur milieu, pourraient reproduire le procede argumentaire pour l’appliquer a une situation clinique problematique.
Herstellung und Charakterisierung von Mangan dotierten III-V Halbleiterheterostrukturen

Gegenstand dieser Arbeit ist das Wachstums von Mangan dotierten III-V Halbleiterheterostrukturen mittels Molekularstrahlepitaxie. Die Charakterisierung erfolgte im Wesentlichen mit Magnetotransportmessungen bei Temperaturen von 300K bis 20mK und Magnetfeldern bis 19T. Es wurden zum einen ferromagnetische GaMnAs Schichten und zum anderen mit Mn magnetisch modulationsdotierte zweidimensionale Ladungstragersysteme untersucht. Bei der Herstellung der ferromagnetischen GaMnAs Schichten stand die Verbesserung der elektrischen und magnetischen Eigenschaften im Mittelpunkt. Hauptziel war es, das Wachstum fur die Integration der GaMnAs Schichten in weiterfuhrende Heterostrukturen zu optimieren. Die Verbesserung der Kristallqualitat und der Einfluss der Pufferschichten, waren von zentralem Interesse. Es konnten GaMnAs Schichten auf (001), (311)A und (311)B orientierten GaAs Substraten mit derzeit aktuellen Curietemperaturen hergestellt werden. Zusatzlich wurde das Wachstum ferromagnetischer GaMnAs Schichten auf nichtpolaren (110) GaAs Substraten etabliert und anschliesend auf das Uberwachsen von [110] Spaltkanten ubertragen. Als erste Anwendung wurden mit diesem Verfahren magnetische bipolare p-n Ubergange hergestellt. Fur die Realisierung magnetischer zweidimensionaler Lochsysteme wurden In0.75Al0. 25As/In0.75Ga0. 25As/InAs Quantenwellstrukturen verwendet. Da fur diese Strukturen keine geeigneten Substrate zur Verfugung stehen, mussen auf herkommliche (001) GaAs Substrate zunachst Pufferschichten zur Verspannungsrelaxierung hergestellt werden, bei denen der In-Gehalt graduell erhoht wird. Zur Kontrolle dieser Schichten wurden zunachst Si-dotierte zweidimensionale Elektronensysteme auf diesen Pufferschichten hergestellt. Es wurde sowohl an den 2DEGs, als auch an den M2DHGs Magnetotransportexperimente durchgefuhrt. Die Transportmessungen bei tiefen Temperaturen, insbesondere im mK-Bereich lieferten bei den magnetischen zweidimensionalen Lochsystemen einige uberraschende Ergebnisse. Wahrend bei allen Si dotierten Elektronen- und den mit Mn nicht invertiert dotierten Lochsysteme um B=0T schwache Lokalisierungseffekte auftreten, zeigen alle invertiert und beidseitig mit Mn dotierten Strukturen bei senkrecht zur Schichtebene angelegtem Magnetfeld einen enormen Widerstandsanstieg um B=0T. Bei hoheren Magnetfeldern sind jedoch die fur 2D Systeme typischen Shubnikov-de-Haas Oszillationen im Langswiderstand und Hallplateaus im Querwiderstand detektierbar.
A critical review on human serum Paraoxonase-1 in the literature: truths and misconceptions

Abstract Human serum paraoxonase 1 (PON1) appears to play an important role in the development of a large variety of diseases with an inflammatory component including heart disease, diabetes, rheumatic diseases, neurological diseases and cancer. As such PON1 research is rapidly expanding into new biomedical fields. Unfortunately, this rapid expansion has resulted in a number of problems due to poor experimental design and the spreading of misconceptions in the literature. This review seeks to describe the basic properties of PON1 and the problems and misconceptions that have arisen.
Une seule santé « One world, one health »: la place des vétérinaires

Le concept « Un monde, Une seule Santé » est un concept émergent qui intègre les relations existant entre la, la santé de l’Homme (santé publique) et l’environnement. Il souligne l’importance d’une démarche conjointe des acteurs de ces différents domaines visant à contrôler les risques sanitaires, s’agissant notamment des maladies transmissibles, émergentes ou ré-émergentes, d’origine animale. Les grands organismes internationaux en charge de la santé publique et de la santé animale (OMS, FAO et OIE) ont établi des relations conventionnelles visant au dépistage précoce de ces maladies ainsi qu’à la mise en oeuvre de méthodes communes propres à les contrôler. Ils s’efforcent, entre autre, de reconnaître et d’évaluer l’impact des perturbations de notre environnement sur leur apparition. Ils interviennent encore dans le domaine de la thérapeutique, s’agissant de la préservation des traitements appliqués conjointement à l’Homme et à l’Animal et notamment de l’Antibiothérapie. Leur domaine de compétence s’étend naturellement à l’ensemble de la planète. Tant par leur contribution au sein de ces grands organismes que par leur pratique quotidienne, les vétérinaires contribuent très activement à l’application du concept « Une seule Santé ».
