Privacy-Preserving Payment Splitting
Authors: Eskandarian Saba , Christodorescu Mihai , Mohassel Payman 
Published: May 2020

AbstractWidely used payment splitting apps allow members of a group to keep track of debts between members by sending charges for expenses paid by one member on behalf of others. While offering a great deal of convenience, these apps gain access to sensitive data on users’ financial transactions. In this paper, we present a payment splitting app that hides all transaction data within a group from the service provider, provides privacy protections between users in a group, and provides integrity against malicious users or even a malicious server.The core protocol proceeds in a series of rounds in which users either submit real data or cover traffic, and the server blindly updates balances, informs users of charges, and computes integrity checks on user-submitted data. Our protocol requires no cryptographic operations on the server, and after a group’s initial setup, the only cryptographic tool users need is AES.We implement the payment splitting protocol as an Android app and the accompanying server. We find that, for realistic group sizes, it requires fewer than 50 milliseconds per round of computation on a user’s phone and the server requires fewer than 300microseconds per round for each group, meaning that our protocol enjoys excellent performance and scalability properties.
A Framework of Metrics for Differential Privacy from Local Sensitivity
Authors: Laud Peeter , Pankova Alisa , Pettai Martin 
Published: May 2020

AbstractThe meaning of differential privacy (DP) is tightly bound with the notion of distance on databases, typically defined as the number of changed rows. Considering the semantics of data, this metric may be not the most suitable one, particularly when a distance comes out as larger than the data owner desired (which would undermine privacy). In this paper, we give a mechanism to specify continuous metrics that depend on the locations and amounts of changes in a much more nuanced manner. Our metrics turn the set of databases into aBanach space. In order to construct DP information release mechanisms based on our metrics, we introducederivative sensitivity, an analogue to local sensitivity for continuous functions. We use this notion in an analysis that determines the amount of noise to be added to the result of a database query in order to obtain a certain level of differential privacy, and demonstrate that derivative sensitivity allows us to employ powerful mechanisms from calculus to perform the analysis for a variety of queries. We have implemented the analyzer and evaluated its efficiency and precision.
Listen Only When Spoken To: Interpersonal Communication Cues as Smart Speaker Privacy Controls
Authors: Mhaidli Abraham , Venkatesh Manikandan Kandadai , Zou Yixin , Schaub Florian 
Published: May 2020

Abstract
Internet of Things and smart home technologies pose challenges for providing effective privacy controls to users, as smart devices lack both traditional screens and input interfaces. We investigate the potential for leveraging interpersonal communication cues as privacy controls in the IoT context, in particular for smart speakers. We propose privacy controls based on two kinds of interpersonal communication cues – gaze direction and voice volume level – that only selectively activate a smart speaker’s microphone or voice recognition when the device is being addressed, in order to avoid constant listening and speech recognition by the smart speaker microphones and reduce false device activation. We implement these privacy controls in a smart speaker prototype and assess their feasibility, usability and user perception in two lab studies. We find that privacy controls based on interpersonal communication cues are practical, do not impair the smart speaker’s functionality, and can be easily used by users to selectively mute the microphone. Based on our findings, we discuss insights regarding the use of interpersonal cues as privacy controls for smart speakers and other IoT devices.
Perspective: Physiological Benefits of Short-Chain Fatty Acids from Cereal Grain Fibre Fermentation and Metabolic Syndrome
Authors: Havensone Guna , Meija Laila , Lejnieks Aivars 
Published: May 2020

Abstract
Currently, intervention studies in humans have demonstrated that dietary fibre and whole grain consumption increase gut bacterial diversity. However, low-fibre intake drives depletion of the human gastrointestinal microbiota and indirectly stimulates metabolic abnormalities linked to metabolic syndrome insulin-resistance and abdominal obesity. The aim of the current paper was to summarise current evidence for the effect of consumption of cereal fibres on gut microbiota composition and their metabolites. By increasing the daily consumption of cereal fibre, the gut micro-biota diversity should have positive impact on the host’s health.

Published: May 2020

Abstract
For many years, there has been a concern that inflammatory bowel disease carries an increased lymphoma risk. At the same time, patients with intestinal lymphomas are occasionally misdiag-nosed as having Crohn’s disease. We report a case of T-cell lymphoma of the bowel misdiag-nosed as Crohn’s disease, which illustrates the diagnostic challenges posed by peripheral extranodal lymphomas. A 68-year old female presented with clinical symptoms (diarrhoea, abdominal pain, poor appetite and significant weight loss), and colonoscopic and initial histological findings that were similar to inflammatory bowel disease. She was diagnosed with Crohn’s disease and received treatment with sulfasalazine with subsequent improvement of symptoms. Eight months after the initial diagnosis the patient experienced sudden abdominal pain. Laparotomy revealed necrosis in the small and large intestine and ileostomy was performed. On day 10 of a complicated postoperative period the patient died. Post-mortem histopathological examination of small and large intestine revealed highly malignant peripheral T-cell lymphoma, not otherwise specified. Differentiation of intestinal T-cell lymphoma from Crohn’s disease continues to be a challenge, because clinical, colonoscopic, radiological and histopathological findings can mimic Crohn’s disease. Careful multi-disciplinary assessment and knowledge of this rare disorder is crucial for timely diagnosis.
1. Period Influence on the Work of Johann Sebastian Bach
Authors: Medňanský Karol 
Published: May 2020

Abstract
The work of Johann Sebastian Bach (1685 - 1750), significantly influences the work of the contemporary composers even almost 270 years after his death. It is undoubtedly caused also by the fact that by his work Bach impersonates contemporary musical tradition. There are the three most significant areas in his work – the influence of family tradition on his work, which we can observe throughout the Thuringia, where they have had a significant musical position for 200 years in all the areas of music – secular, urban, spiritual and ecclesiastical. The tradition of German music is not less important. It influenced Johann Sebastian Bach during his studies and was based directly on the essence of protestant educational principle. Filip Melanchton, the most significant collaborator and a friend of Martin Luther, was contributory in the reform of this principle. The most important is the influence of Luther’s Reformation on the spiritual world of J. S. Bach, which reached such dimensions that he unites theology and music. Under the influence of the aforementioned three areas, the work of Bach has acquired exceptional artistic and spiritual quality, a unique phenomenon in the history of music.
6. Teaching Strategies Employed to Approach a Postmodern Opus. Recital I (For Cathy) by Luciano Berio
Authors: Iațeșen Loredana Viorica 
Published: May 2020

Abstract
The difficulties encountered by any history of music teacher when tackling postmodern repertoire is a well-known fact. Doubts are only natural. For instance, of the innumerable creators belonging to different cultures, which would be the relevant composers? Furthermore, when finally choosing one representative, on which of his/her works should one focus? And after one particular piece of selected, what is the best way to teach the scientific arguments required for its perception? When the chosen opus fails to distinguish itself through the direct expressiveness of its language, what should one do? What are the works of music considered to be exquisite in terms of technique and expression, with an actual impact on the teaching field? This approach is all the more tedious as the specialized teacher is faced with the lack of any immediate feedback about the importance of some music, as the biggest impediment is the music score itself, which becomes gradually accessible, after numerous auditions and explanatory comments. Therefore, the purpose of this research was to achieve the teaching approach of an opus with direct expressiveness composed during the last decades of the last century: Recital I for Cathy by Luciano Berio. An innovative mezzo soprano and 17 instruments score, which promotes the subtleties existing either in the relationship between themes, dramaturgy and language, or in the correspondence between text and sonority. These are some of the aspects that we intend to tackle in order to help our students understand the postmodern phenomenon by means of Berio’s inclusive and synthetic vision. In order to ground our scientific approach, we rely on the well-known quotation technique used by the creator, which, by recalling apparently disparate music, facilitates the process of didactic demonstration. The actual quotation or allusion to different sonorities constitutes a challenge in discovering the general and particular meanings of sound dramaturgy, but especially the deep meanings of the emotional reception of the opus.

Abstract
The history of Physical Education reports us that the physical exercises have emerged and have been perfected in accordance with the social order, evolving in direct relation with it. During this paper we will define the phenomenon of Physical education and sport as a discipline of academic education, starting from the general notions to the particular ones in the general physical training of the student actor. In this paper we try to highlight some similarities between the preparation of the actor and the preparation of the athlete for professional performance. We will present the theoretical framework with well-defined and accepted notions in both sports and theater. We will subsequently present the particular framework in which the theoretical principles in the sports field are taken over by the university theater programme and put into practice for the general preparation of the future actor. The article closes with the selection of some basic conclusions and recommendations appropriate to the topic under discussion
3. The Graphic Communication Actor: Generating Visual Rhetoric for Development Initiatives
Authors: Ebigbagha Sylvester Zifegha 
Published: May 2020

Abstract
The art of using language for public expression in order to persuade target audience to support development initiatives is a key reason for graphic communication. This requires communication actors particularly, the graphic encoder to know salient input and output variables of communication for effective mediation. However, the prevalence ignorance of these variables, often results in ineffective media production that is counter-productive to development. Therefore, this paper focused on production of practical rhetoric in graphic language for development programmes. The paper employed the critical-historical-analytic examination and content analysis methods. It introduced the reader to the need for practical rhetoric in visual communication. Furthermore, it highlighted the salient input and output variables that the graphic communication actor need be conversant with in order to produce visual rhetoric, using the McGuire’s Communication/persuasion Matrix. And it exemplified graphic media that result from application or neglect of the knowledge of the variables. The paper found that consideration of the variables afforded production of effective rhetoric in graphic language. The paper ended with the need for graphic encoders to internalize knowledge of the input and output variables and utilize it during the process of media production to generate visual rhetoric with desired effect.

Thromboelastography in pre-surgery monitoring in Hemophilia A with high inhibitor titer: case report and literature review
Authors: Melen Brinza , Uscatescu Valentina , Gheorghe Georgiana , Chiriac Elisabeta , Ciobanu Claudia , Orban Horia , Coriu Daniel 
Published: May 2020

Abstract
The development of factor VIII inhibitors (allo-antibodies) continues to be a major complication in the management of severe forms of hemophilia A, especially as far as treatment and treatment response monitoring is concerned. The need to implement a reliable laboratory assay is all the more obvious if major surgery occurs, when conventional tests (activated partial thromboplastin time APTT, prothrombin time PT, factor VIII level) are of no avail and there is a very fragile balance between bleeding and thrombosis.
We report the case of a 32 year-old patient diagnosed with severe Hemophilia A, referred to the Comprehensive Center for the Diagnosis and Treatment of Hemophilia of the Fundeni Clinical Institute for a multidisciplinary assessment in view of a total left hip arthroplasty due to aseptic necrosis of the femoral neck.
Workup showed a high inhibitor titer (>200 BU). Taking into consideration the interindividual variability of the response to bypassing agents, as well as the bleeding risk associated with a major orthopedic surgery, we used thromboelastography (TEG) to assess the patient’s response to aPCC (activated prothrombin complex concentrate) and rFVIIa (activated recombinant factor VII). The findings helped select the optimal replacement scheme to ensure perioperative hemostasis.
Influence of No-Till Technology on Reducing Soil Degradation During Sorghum Cultivation
Authors: Kabelka D. , Kincl D. , Vopravil J. 
Published: May 2020

Abstract
Soil degradation and water erosion are undoubtedly serious global problems. Moreover, excessive surface runoff and the lack of water in landscape are problems encountered not only in the Czech agricultural land. This condition is unsustainable in the long-term and it is necessary to find, verify and quantify suitable agricultural methods for reducing soil degradation. In this study, we tested two soil conservation technologies for sorghum (Sorghum bicolor) cultivation. Our results show that erosion was reduced by more than 78% (no-till) and 89% (no-till: narrow row) in rainfall simulation on naturally moist soil compared to conventional cultivation. Also, the use of conservation technologies reduced surface runoff (52% no-till, 68% no-till: narrow row). Sorghum has similar agronomic requirements as maize but it has the advantage of a good dryness tolerance and a high water use efficiency. The two-year research (2014, 2017) took place in the Central Bohemian Region. Soil degradation was verified using a rainfall simulator. The results have shown that both no-till technologies have a significant (P < 0.05) soil conservation effect.
Infrared Thermography Diagnostics of Air Permeability Through Building Openings – Assessment of its Reliability
Authors: Bielek Boris , Szabó Daniel , Čurpek Jakub , Suchánek Peter , Panáček Pavol 
Published: May 2020

Abstract
The presented paper deals with an analysis of the reliability of a diagnostic method of air permeability through building openings (windows, doors, glass walls) by the application of infrared thermography. A test sample of a plastic double casement window was experimentally tested for air permeability and watertightness in a large pressure chamber. Different levels of the tightness were adjusted between the casement and frame part of the window. Additionally, the window test sample was measured in the large climate chamber with variant air pressure differences. Moreover, the surface temperatures were measured on the window by thermocouples and subsequently compared with images directly taken by infrared thermography. The effect of the increased air infiltration can be detected by infrared thermography but cannot quantify the overall air permeability of the window. The distribution of the exterior window surface temperature is influenced by several factors which should be taken into consideration in the final assessment of the window.
Non-Linear Analysis of an RC Beam Without Shear Reinforcement with a Sensitivity Study of the Material Properties of Concrete
Authors: Sucharda Oldrich , Mateckova Pavlina , Bilek Vlastimil 
Published: May 2020

Abstract
A detailed analysis of concrete structures requires knowledge of the mechanical properties of the materials used. In the case of a non-linear analysis, the scope of the information needed is even greater. In particular, the tensile strength and fracture-mechanical parameters are required for the concrete. Prospective approaches that could increase the informative value of detailed analyses include the use of stochastic modelling. It particularly enables the definition of the effects of individual input parameters on the load capacity, failure mode, and general behaviour of the structure. The presented paper aims at a detailed analysis of a reinforced-concrete beam without shear reinforcement, which is based on a complex set of laboratory tests and non-linear analyses with a sensitivity study. The laboratory program includes different types of laboratory tests. Selected and missing material parameters of the concrete are calculated according to recommendations in scientific papers and the valid standards. The results are compared and discussed.
Performance of Quiet Helicopter
Authors: Stanisławski Jarosław 
Published: May 2020

Abstract
Noise generated by helicopters is one of the main problems associated with the operation of rotorcrafts. Requirements for reduction of helicopter noise were reflected in the regulations introducing lower limits of acceptable rotorcraft noise. A significant source of noise generated by helicopters are the main rotor and tail rotor blades. Radical noise reduction can be obtained by slowing down the blade tips speed of main and tail rotors. Reducing the rotational speed of the blades may decrease rotor thrust and diminish helicopter performance. The problem can be solved by attaching more blades to main rotor. The paper presents results of calculation regarding improvement of the helicopter performance which can be achieved for reduced rotor speed but with increased number of rotor blades. The calculations were performed for data of hypothetical light helicopter. Results of simulation include rotor loads and blade deformations in chosen flight conditions. Equations of motion of flexible rotor blades were solved using the Galerkin method which takes into account selected eigen modes of the blades. The simulation analyzes can help to determine the performance and loads of a quiet helicopter with reduced rotor speed within the operational envelope of helicopter flight states.
Body Training Systems of Stage Movement Courses, in the Drama School of Iasi City
Authors: Florentin Alice-Ioana , Florentin Emanuel 
Published: May 2020

Abstract
The contemporary choreographic movement of the 21st century may be viewed as a true patchwork of performance techniques and styles; a build-up of movements taken from established techniques, with elements of drama, ballet, improvisation and other connected disciplines. These challenges may be met only by a multi-technical and multi-stylistic approach in the training of future actors and choreographers. The transition from the everyday body to the theater body is the result of a process based on self-knowledge, documentation and practice.
Mime Language. From Singularity To Community
Authors: Mateiciuc Ioan 
Published: May 2020

Abstract
This article approaches the subject of theatrical language in mime, aiming to identify the mechanisms and resources of stage performance, referring itself to the silence/speech binomial. Can mime impose a valid theatrical language? Will a type of structuralism, through a reduction of complexities, manage to encompass the essence of the implications of stage acting within social structures? We will see the extent to which theater can trace a pattern of collective mime language socially and the extent to which such an approach will manage to encompass the interaction of the mind with an external reality, while also analysing the ability of the performer – when the latter understands their own mind or creates maps of their own mind or of the community – to create a sort of cognitive empathy, resulting in an extraction of a theory of collectivity, which is, most often, ignored in such a cultural performance as mime, and its protagonists may or may not find a place in a social mind.
