Identity-Concealed Authenticated Encryption and Key Exchange

Identity concealment and zero-round trip time (0-RTT) connection are two of current research focuses in the design and analysis of secure transport protocols, like TLS1.3 and Google's QUIC, in the client-server setting. In this work, we introduce a new primitive for identity-concealed authenticated encryption in the public-key setting, referred to as higncryption, which can be viewed as a novel monolithic integration of public-key encryption, digital signature, and identity concealment. We then present the security definitional framework for higncryption, and a conceptually simple (yet carefully designed) protocol construction. As a new primitive, higncryption can have many applications. In this work, we focus on its applications to 0-RTT authentication, showing higncryption is well suitable to and compatible with QUIC and OPTLS, and on its applications to identity-concealed authenticated key exchange (CAKE) and unilateral CAKE (UCAKE). Of independent interest is a new concise security definitional framework for CAKE and UCAKE proposed in this work, which unifies the traditional BR and (post-ID) frameworks, enjoys composability, and ensures very strong security guarantee. Along the way, we make a systematically comparative study with related protocols and mechanisms including Zheng's signcryption, one-pass HMQV, QUIC, TLS1.3 and OPTLS, most of which are widely standardized or in use.
Density dependence of two-body interactions for beyond mean-field calculations

This paper deals with the theoretical foundation of effective two-body forces for the generator coordinate method and the projected mean-field method. The first aim of this paper is to reduce the in-medium content of a generalized G matrix, removing the hard-core problem in this extended context, into various local densities. Then, we consider the possible renormalization of multibody forces through a density-dependent two-body interaction in the context of configuration mixing calculations. A density dependence of the form ${\ensuremath{\rho}}^{\ensuremath{\sigma}},$ as used in Skyrme and Gogny forces, is successfully interpreted as doing so when the mixed density is used. Finally, we propose a simple extension of the Skyrme force dedicated to the calculation of matrix elements between nonorthogonal product states, which are needed to evaluate the correlated energy.
Direct Presentation Is Sufficient for an Efficient Anti-Viral CD8+ T Cell Response

The extent to which direct- and cross-presentation (DP and CP) contribute to the priming of CD8+ T cell (TCD8+) responses to viruses is unclear mainly because of the difficulty in separating the two processes. Hence, while CP in the absence of DP has been clearly demonstrated, induction of an anti-viral TCD8+ response that excludes CP has never been purposely shown. Using vaccinia virus (VACV), which has been used as the vaccine to rid the world of smallpox and is proposed as a vector for many other vaccines, we show that DP is the main mechanism for the priming of an anti-viral TCD8+ response. These findings provide important insights to our understanding of how one of the most effective anti-viral vaccines induces immunity and should contribute to the development of novel vaccines.
Resource Partitioning for Multi-Party Real-Time Communication

For real-time communication services to achieve widespread usage, it is important that the network's management be allowed to control the services eeectively. An important management capability concerns resource partitioning, i.e., distributing the diierent resources available at any given server (network node or link) among a number of partitions, where the admission control and establishment computations for a given connection need to consider only the connections in the same partition, and are completely independent of the connections accepted in other partitions. Resource partitioning is useful for a number of applications, including the creation of virtual private subnetworks, and of mechanisms for advance reservation of real-time network services, fast establishment of real-time connections, and mobile computing with real-time communication. In previous work, we presented a scheme for resource partitioning in a guaranteed performance networking environment with EDD-based packet scheduling disciplines. We now present the results of our continuing research, giving admission control tests for resource partitioning for two additional scheduling disciplines, FIFO and RCSP, as well. We also simulate our resource partitioning scheme in a multi-party application scenario. Our simulations connrm that resource fragmentation losses due to resource partitioning are small, and that resource partitioning reduces the admission control computation overhead. A somewhat surprising result from the simulation experiments is that, under circumstances that arise naturally in multi-party communication scenarios, resource partitioning results in higher overall connection acceptance rate.
KESOSD: keyword search over structured data

Most of the information on the Web can be currently classified according to its (information) structure in three different forms: unstructured (plain text), semi-structured (XML files) and structured (tables in a relational database). Currently Web search is the primary way to access massive information. Keyword search also becomes an alternative of querying over relational databases and XML documents, which is simple to people who are familiar with the use of Web search engines. There are several approaches to perform keyword search over relational databases such as Steiner Trees, Candidate Networks and Tuple Units. However these methods have some constraints. The Steiner Trees method is considered a NP-hard problem, moreover, a real databases can produce a large number of Steiner Trees, which are difficult to identify and index. The Candidate Network approach first needs to generate the candidate networks and then to evaluate them to find the best answer. The problem is that for a keyword query the number of Candidate Networks can be very large and to find a common join expression to evaluate all the candidate networks could require a big computational effort. Finally, the use of Tuple Units in a general conception produce very large structures that most of the time store redundant information. To address this problem we propose a novel approach for keywords search over structured data (KESOSD). KESOSD models the structured information as graphs and proposed the use of a keyword-structure-aware-index called KSAI that captures the implicit structural relationships of the information producing fast and accuracy search responses. We have conducted some experiments and the results show that KESOSD achieves high search efficiency and high accuracy for keyword search over structured data.
REVIEW OF SUPPORT TO SITUATIONAL REQUIREMENT ENGINEERING FROM STANDARDS AND MODELS

Requirement engineering (RE) process clear description can be an important factor for guiding the team members involved in the RE process, which may help organizations not exceeding the estimated schedule and budget for the software project. There can be many reasons of not having efficient RE process such as changing situations among the organizations involved in the RE process. It is certainly one of the various other reasons of having non-efficient RE process. Due to these changing situations the RE process customization accordingly should be performed. As part of our current research project, where we are investigating situational RE in Global Software Development (GSD), first we need to identify the factors which may results in changing situations. This paper we have critically reviewed the domain of “standards and models”, and identified the initial list of situational factors from them. These standards and models are related to software engineering, which directly or indirectly discusses RE process. We have adopted the constant comparison and memoing techniques of the Grounded theory for identification of unique initial list of the situational factors. This initial list is a significant consideration for a comprehensive list of situational factors affecting RE process in GSD.
Efficacy and safety of QVA149 compared to the concurrent administration of its monocomponents indacaterol and glycopyrronium: the BEACON study

Introduction The BEACON study evaluated the efficacy and safety of QVA149, a once-daily dual bronchodilator containing a fixed-dose combination of the long-acting β2-agonist (LABA) indacaterol and long-acting muscarinic antagonist (LAMA) glycopyrronium (NVA237), in development for the treatment of patients with chronic obstructive pulmonary disease (COPD), compared with the free-dose concurrent administration of indacaterol plus glycopyrronium (IND+GLY). Methods In this multicenter, double-blind, parallel group study, patients with stage II or stage III COPD (Global initiative for chronic Obstructive Lung Disease [GOLD] 2010) were randomized (1:1) to once-daily QVA149 (110 μg indacaterol/50 μg glycopyrronium) or concurrent administration of indacaterol (150 μg) and glycopyrronium (50 μg) via the Breezhaler® device (Novartis AG, Basel, Switzerland) for 4 weeks. The primary endpoint was to evaluate the noninferiority of QVA149 as compared with concurrent administration of IND+GLY, for trough forced expiratory volume in 1 second (FEV1) after 4 weeks of treatment. The other assessments included FEV1 area under the curve from 0 to 4 hours (AUC0–4 hours) at day 1 and week 4, symptom scores, rescue medication use, safety, and tolerability over the 4-week study period. Results Of 193 patients randomized, 187 (96.9%) completed the study. Trough FEV1 at week 4 for QVA149 and IND+GLY was 1.46 L ± 0.02 and 1.46 L ± 0.18, respectively. The FEV1 AUC0–4 hours at day 1 and week 4 were similar between the two treatment groups. Both treatment groups had a similar reduction in symptom scores and rescue medication use for the 4-week treatment period. Overall, 25.6% of patients in QVA149 group and 25.2% in the IND+GLY group experienced an adverse event, with the majority being mild-to-moderate in severity. No deaths were reported during the study or during the 30 days follow-up period. Conclusion The BEACON study demonstrated that once-daily QVA149 provides an efficacy and safety profile similar to the concurrent administration of its monocomponents indacaterol and glycopyrronium.
Youth culture and discipline at a school in the Western Cape

Internationally, contemporary youth struggle to make sense or meaning of their lives. That is so because they live in a world where they daily witness unsolvable problems of struggling economies, poverty, HIV, and religious and national conflict, and where they are generally treated with ambivalence and a threat to the existing social order. Youth also struggle because within the public imagination they exist on the fringe of society. Giroux (2012: 2) argues that youth are given few spaces where “they can recognise themselves outside of the needs, values, and desires preferred by the marketplace” and are mostly subjected to punitive and zero tolerance approaches when they behave in unacceptable ways. In South Africa presently, it is generally claimed that “discipline problems” amongst youth have become the most endemic problem in South African schools, with policy makers and educators daily complaining about the disciplinary problems within schools that affect how learners engage with learning. Equally, discipline as punitive coercion has been shown to be an unsuccessful educational method in dealing with youth (Porteus & Vally 1999). With the above schooling challenge in mind, this qualitative study explored the views of thirteen young learners at Avondale High School in the Western Cape on school discipline. Via semi-structured interviews, the youth were asked about their understandings of the rules, disciplinary structures, forms of authority and order at the school, how they interpreted the role of discipline, and how they thought this would influence the futures awaiting them. The goal of the study was to provide a multi-dimensional view of what youth regarded as discipline at one school, and to explore whether different learners adopted different meanings of ‘discipline’ according to the context of their individual lives. I show in the study utilising the views of Emile Durkheim, Michel Foucault and Pierre Bourdieu that school discipline needs to be thought of as more than punishment or structures of ordering per se if it is to play a productive role in the functioning of schools. Along with Yang (2009: 49) I suggest that only when schools recognise that discipline has multiple meanings and (limited) roles within their daily functioning, will the emancipatory and transformative possibilities of school discipline be unlocked. For that to happen, the voices and views of youth in schools have to be taken account of, and meaningful relationships developed between learners, educators, and school management.

RV IS : ” scalable ” visualization of generic association rules

The extremely large number of association rules that can be drawn from –even reasonably sized– datasets has bootstrapped the development of more acute techniques or methods to reduce the size of the reported rule sets. In order to be reliable in a decision making process, such discovered rules have to be both concise and easily understandable for users, and/or as an input to visualization tools [1]. Even though considered as a key step in the KDD process, association rule visualization received much less attention than that paid to the extraction step, however. In this paper, we present, GERVIS, a graphical visualization prototype for handling generic bases of association rules. GERVIS’s main originality is based on the fact that it uses a back-end meta-knowledge formally expressed by means of fuzzy metaassociation rules. This meta-knowledge allows a cooperative exploration of generic bases of association rules. Besides displaying on user demand associated derivable rules, the additional knowledge– highlighting connected rules to a userselected rule– provides an improvement of human-machine interaction.
Near-horizon microstates of the D1-D5-P black hole

We construct probe solutions in the attractor background of the five-dimensional D1-D5-P black hole which represent near-horizon microstates in the limit of large D1-charge. These generalize the corresponding solutions considered by Gaiotto, Strominger and Yin for the 4-dimensional D0-D4 black hole. Using U-duality and a 4D-5D connection, we argue that the relevant configurations are bound states of D1-branes that have expanded through the Myers effect to form a Kaluza-Klein monopole wrapping the black hole horizon. We show that these branes experience a magnetic field on their moduli space, and that the degeneracy of lowest Landau levels reproduces the Bekenstein-Hawking entropy.
Monetary Policy in Korea through the lense of Taylor Rule in DSGE model

This paper shows assessments on the monetary policy of Korea based on an estimated model. During the sample period of the in ation targeting scheme, the monetary policy discretion, which is the monetary policy shock after the historical decomposition of the model, has been mostly in ationary while it was reducing the volatility of output growth and thus countercyclical. 3% target rate could have been achieved when the monetary policy shock's standard deviation was approximately half of its posterior estimate. Various degree of monetary policy stance has been simulated with the sample period. An aggressive monetary policy towards in ation stabilization would have generally led to the average level of in ation rate closer to its target rate but at the cost of higher volatilities of the output growth.
Does the beat go on?: identifying rhythms from brain waves recorded after their auditory presentation

Music imagery information retrieval (MIIR) systems may one day be able to recognize a song just as we think of it. As one step towards such technology, we investigate whether rhythms can be identified from an electroencephalography (EEG) recording taken directly after their auditory presentation. The EEG data has been collected during a rhythm perception study in Kigali, Rwanda and comprises 12 East African and 12 Western rhythmic stimuli presented to 13 participants. Each stimulus was presented as a loop for 32 seconds followed by a break of four seconds before the next one started. Using convolutional neural networks (CNNs), we are able to recognize individual rhythms with a mean accuracy of 22.9% over all subjects by just looking at the EEG recorded during the silence between the stimuli.
Scientific Methods Ought to Be Public , and Descriptive Experience Sampling Is One of Them

Hurlburt and Schwitzgebel’s groundbreaking book, Describing Inner Experience: Proponent Meets Skeptic, examines a research method called Descriptive Experience Sampling (DES). DES, which was developed by Hurlburt and collaborators, works roughly as follows. An investigator gives a subject a random beeper. During the day, as the subject hears a beep, she writes a description of her conscious experience just before the beep. The next day, the investigator interviews the subject, asks for more details, corrects any apparent mistakes made by the subject, and draws conclusions about the subject’s mind. Throughout the book, Schwitzgebel challenges some of Hurlburt’s specific conclusions. Yet both agree – and so do I – that DES is a worthy method.
Extracellularly Recorded Somatic and Neuritic Signal Shapes and Classification Algorithms for High-Density Microelectrode Array Electrophysiology

High-density microelectrode arrays (HDMEA) have been recently introduced to study principles of neural function at high spatial resolution. However, the exact nature of the experimentally observed extracellular action potentials (EAPs) is still incompletely understood. The soma, axon and dendrites of a neuron can all exhibit regenerative action potentials that could be sensed with HDMEA electrodes. Here, we investigate the contribution of distinct neuronal sources of activity in HDMEA recordings from low-density neuronal cultures. We recorded EAPs with HDMEAs having 11,011 electrodes and then fixed and immunostained the cultures with β3-tubulin for high-resolution fluorescence imaging. Immunofluorescence images overlaid with the activity maps showed EAPs both at neuronal somata and distal neurites. Neuritic EAPs had mostly narrow triphasic shapes, consisting of a positive, a pronounced negative peak and a second positive peak. EAPs near somata had wide monophasic or biphasic shapes with a main negative peak, and following optional positive peak. We show that about 86% of EAP recordings consist of somatic spikes, while the remaining 14% represent neuritic spikes. Furthermore, the adaptation of the waveform shape during bursts of these neuritic spikes suggested that they originate from axons, rather than from dendrites. Our study improves the understanding of HDMEA signals and can aid in the identification of the source of EAPs.
Modelling fracture formation in bi-layered materials , with applications to tree bark and drying mud

In this paper we present a model of fracture formation on surfaces of bi-layered materials. The model allows synthesis of realistic patterns occurring in nature as a result of cracking induced by growth or shrinkage of one layer with respect to another. Two different discretizations of the problem are discussed. First we revisit an existing mass-spring approach, then we introduce an approach based on a finite element method. We apply the FEM model to synthesize crack patterns occurring in tree bark and drying mud, and present results.
Baseline Parametric Survey on Causes of Traffic Congestion in Datacenter Networks

Distributed cloud datacenters are currently used as deployment environment for large-scale web-facing enterprise analytic cloud applications. In the era of cloud computing, these networks allow unprecedented scalability in response to dynamic and unpredictable grid workloads. However, grid applications need to scale beyond the limits of single-tenanted datacenter to multi-tenanted datacenter sites providing regulatory service level compliance, efficient Quality of Service (QoS) and increased fault tolerance at all times. Following the complex hierarchical design structure of emerging cloud networks such as Internet of Things (IoT) and Fog Computing Networks (FCNs), congestion crisis becomes a critical consideration for future expansion of these networks. This paper carried out a Baseline Parametric Survey (BPS) to ascertain major factors of DCN traffic congestion in selected production networks in Nigeria. From the survey, it was observed that the absence of an intelligent load balancer, bandwidth size, network traffic type, and network switch butter capacity, number of users on the network, segmentation and routing devices all contribute to network congestion incidence. The deductions from this work can be used to implement a Fog internet layer for smarter data off-loading in today’s internet of everything.
