Achieving secure and efficient lattice-based public-key encryption: the impact of the secret-key distribution

Lattice-based public-key encryption has a large number of design choices that can be combined in diverse ways to obtain different tradeoffs. One of these choices is the distribution from which secret keys are sampled. Numerous secret-key distributions exist in the state of the art, including (discrete) Gaussian, binomial, ternary, and fixed-weight ternary. Although the choice of the distribution impacts both the concrete security and performance of the schemes, it has not been compared explicitly how the choice of secret-key distribution affects this tradeoff. In this paper, we compare different aspects of secret-key distributions that appear in submissions to the NIST post-quantum standardization effort. We first consider their impact on concrete security (influenced by the entropy and variance of the distribution), on decryption failures and IND-CCA2 security (influenced by the probability of sampling keys with “non average, large” norm), and on the key sizes. Next, we select concrete parameters of an encryption scheme instantiated with the above distributions, optimized for key sizes, to identify which distribution(s) offer the best tradeoffs between security and performance. We draw two main conclusions from the results of the above optimization. Firstly, fixed-weight ternary secret keys result in the smallest key sizes of the encryption scheme. Such secret keys reduce the decryption failure rate and hence allow for a higher noise-to-modulus ratio, alleviating the slight increase in lattice dimension required for countering specialized attacks that apply in this case. Secondly, fixed-weight ternary secret keys result in the scheme becoming more secure against decryption failurebased IND-CCA2 attacks, as compared to secret keys with independently sampled components.
Contact toxicity and persistence of essential oils from Foeniculum vulgare , Teucrium polium and Satureja hortensis against Callosobruchus maculatus ( Fabricius ) ( Coleoptera : Bruchidae ) adults Foeniculum vulgare , Teucrium polium and Satureja hortensis uçucu

Contact toxicity and persistence of essential oils extracted from Foeniculum vulgare Miller (Apiaceae), Teucrium polium L. (Lamiaceae) and Satureja hortensis L. (Lamiaceae) were evaluated against the adults of cowpea seed beetle, Callosobruchus maculatus (Fabricius) at 28±2 °C, 60±5% r.h. in dark conditions. Contact toxicity tests were conducted on one-day old adults of C. maculatus with 6 concentrations of essential oils at 24-h exposure time. The persistence of insecticidal activity of essential oils was examined for a period of 30 h at the LC99 level. The results indicated that mortality of adults was dose related. Males were more susceptible to essential oils than females. The essential oil of F. vulgare was the most toxic to male and female adults of C. maculatus with LC50 values of 390.38 and 513.46 μl. m, respectively. Moreover, S. hortensis oil was more toxic to male and female adults of C. maculatus with LC50 values of 535.69 and 640.99 μl. m than T. polium oil with LC50 values of 1263.09 and 1469.72 μl. m, respectively. The results of persistence tests revealed that essential oil of S. hortensis was the most persistent, while that of T. polium was the least. High persistence of S. hortensis oil could be attributed to its high proportion of oxygenated compounds compared to other oils. The present study demonstrated that these essential oils can be used as appropriate alternative to control of cowpea seed beetle.
Validation note for the ATLAS monophoton analysis : ATLAS EXOT 2014 06

The ATLAS collaboration provides, in the additional material available at [5], a cut flow for one benchmark point for the MSSM scenario with a compressed q̃–χ1 spectrum, where q̃ refers to any of the first and second generation leftand right-handed squarks and χ1 is the lightest neutralino, the lightest SUSY particle, which is assumed to be detector stable. Moreover acceptance and efficiencies, together with production cross sections, are provided for more benchmark points, see Figs. 24–26 in [5]. The signal process consists in the production of a q̃ ̄̃ q pair, with the addition of a hard extra photon, with the subsequent decay of the squarks into a Standard Model (SM) quark and χ1. This process has been generated with MadGraph 5 v1.5. 11 [6] using the following syntax:
If at First You Don’t Succeed: Helping Players Make Progress in Games with Breaks and Checkpoints

Developing skill and overcoming in-game challenges is of great interest to both players and game designers. Players can improve through repetition, but sometimes practice does not lead to improvement and progress stalls. It would be useful if designers could help players make progress without compromising their long-term skill development. We carried out a study to investigate how two techniques—checkpoints and breaks—affect in-game progress and player skill. Checkpoints allow multiple attempts at a challenge without having to repeat earlier sections; this aids progress, but could potentially hinder skill development. Second, breaks in gameplay have been shown to accelerate skill development, but their effectiveness is unknown when the breaks are integrated into the game's design. Our study evaluated the effects of game-integrated breaks and checkpoints on players' in-game progress (when the techniques were present) as well as two test sessions (with all techniques removed). Our results showed that both checkpoints and breaks aid progress (combining both had the largest effect) and that neither technique reduced performance in the transfer task, suggesting that skill development was not hindered. Our work provides evidence that checkpoints and breaks are valuable techniques that can assist both player progress and skill.
PSYCHIATRIC NURSING

89 Özge Kapısız, Perception of dyspnea, anxiety and depression / dx.doi. org/10.14744/phd.2018. 53244 pression. [6,7] In these cases, the anxiety and depression level of the individual is directly correlated with the level of dyspnea. [4,7,8] In the literature, thestudies that look at dyspnea as a subjective experience define it differently for every individual. The studies also show that 100% of patients with COPD experience dyspnea,[6] that patients perceive dyspnea as the worst symptom,[9] and that they live in a state of distress and face limitationsin being able to fulfill vital daily activities. [9,10] All these biopsychosocial problems may result in patients experiencing anxiety and depression. [7,11,12] Anxiety and depression are reported to be the most common mental disorders associated with COPD. [8,13] According to studies from the literature, the prevalence of anxiety is estimated to be between 2–96%,[14,15] while for depression, the approximate prevalence is estimated to be between 6% and 56% in COPD patients. [14,16] Studies that have been carried out withCOPD patients in Turkey have focused on the issues of self-care capability,[12] self-efficacy,[16–18] quality of life,[5,16] anxiety and depression,[4,13,19] and social support,[20] but there are no studies that have examined the relationship between dyspnea and mental health. Therefore, studies that could serve as a guide to healthcare professionals who work with COPD patients are needed. The aim of this study was to evaluate the relationship between the severity of dyspnea and levels of anxiety and depression in COPD patients and to determine other predictive factors for anxiety and depression in an analytic manner.

Communicating for results-organizations in albanian context

During the last 30 years, have changed many concepts, and perspectives, on decision-making; from the normative theories that wanted to improve their decision-making technology because of the limited human rationality, to descriptive theories that have studied the reasons for human actions, with the assumption that these were supplied with the content or meaning in the fact that they had, or that the link between action and its meaning was too poor. Organizational theories recognize the central role of information in organizations. Research gets access to communication information, to analyze how an organization is seeking information about alternative courses of action, to develop principles for designing the organizational structure and to understand the processes by which it creates a common interpretation of its environment. But the main concern of this research is managerial decision making in Albanian context and communication of information then is treated as a contribution to this primary activity. Access to information processing in organizational analysis seeks to understand and predict how organizations perceive the incentives, as they interpret as conserve, recover and transmit information, how form judgments and solve problems. A communication model of organizational information will provide us with a theoretical framework for analyzing organizational needs for information in Albanian context, the processes by which information is obtained and used, and the purposes on the basis of which use information. Focusing on organizational behavior using information, this perspective would be a modest contribution to the large number of studies on the application of information technology and information systems in organizations. The paper aims to compare a selection of perspectives and information in organizations in Albanian context in order to identify some conceptual elements that can be used to build a model of the organization of information and the use of it in decision making.
Parental Role Construction and Parental Involvement in Children's Education.

Following a model suggesting that parental role construction fills specific functions in the parental involvement process (Hoover-Dempsey and Sandler, 1995; in press), this study examined parents' role construction as it relates to children's schooling. A sample of 74 parents of public elementary school children participated in focused interviews about their involvement ideas and activities. Interview transcripts were analyzed for three components of role construction: (1) parents' values, beliefs, goals, and expectations related to their children's development and education; (2) parents' ideas about their responsibilities and reported behaviors in day-to-day education; and (3) parents' ideas about their responsibilities and reported behaviors related to major decisions in the course of the child's education. Data were also gathered on parents' sense of efficacy in helping their children succeed in school, teacher ratings of parent effectiveness in helping the child, and child achievement. Analyses of over 9,000 coded interview statements suggested systematic patterns of links between the values and behavioral components of role construction, between components of role construction and measures of parental efficacy, and teacher-rated parental effectiveness and child achievement. Cluster analyses revealed varied patterns of role construction associated with higher and lower child achievement.

COMPUTATIONAL INVESTIGATION FOR FREE-FLIGHT AERODYNAMICS AND FLIGHT DYNAMICS OF SUBSONIC AND SUPERSONIC PROJECTILES

In the preliminary design of modern projectiles, numerical simulations could provide the researchers with a greater detail for the flow field, aerodynamic forces and flight trajectories which are very difficult to measure accurately in wind tunnel test or real flight test. Therefore, in this paper, our research team has successfully integrated aerodynamics and flight dynamics into a computational simulation system named GMFlow to solve these coupled problems. And for GMFlow, an advanced time-accurate Navier-Stokes computational technique has been employed to compute the unsteady aerodynamics associated with the free flight of the spinning projectiles at subsonic and supersonic speeds, and an innovatively coupled computational fluid dynamics /rigid body dynamics technique has been used to determine flight trajectories of the projectiles. Unsteady numerical results obtained from the coupled method clearly display the flow field, the aerodynamic forces and moments, and the flight trajectories of the projectiles. Computed positions and orientations of the projectiles have been compared with actual data measured from free flight tests and are found to be generally in decent agreement. Therefore, the actual testing and development costs for projectiles design in the near future could be greatly reduced by the coupled technique which can accurately provide the aerodynamics and flight dynamics for these newly designed configurations.
Numerical aspects of nite element simulations of residual stresses in metal matrix composites

When a metal matrix composite (MMC) is cooled down from the fabrication or annealing temperature to room temperature, residual stresses are induced in the composite due to the mismatch of the thermal expansion coe cients of the matrix and reinforcement. A thermomechanical model describing these processes is presented considering that the reinforcement component has a thermo-elastic behaviour and that the matrix material exhibits a thermo-elastoviscoplastic behaviour. The model is implemented with a semi-implicit forward gradient nite element method algorithm and the resulting code is used to perform numerical simulations and calculate thermally induced residual stress elds in MMCs. Several tests are performed on a continuously reinforced MMC and a short cylindrical particle MMC in order to optimize the algorithm and de ne its governing parameters. Good agreement was obtained with results from other authors. Copyright ? 2001 John Wiley & Sons, Ltd.
A new up-conversion charging concept for effectively charging persistent phosphors using low-energy visible-light laser diodes

It is general knowledge in persistent luminescence that high-energy illumination, mostly ultraviolet light, is usually necessary in order to effectively charge persistent phosphors. However, the need for high-energy ultraviolet light excitation compromises some applications. In his pioneering work on ruby (Al2O3:Cr3+) laser materials in 1960, Theodore Maiman observed an excited-state absorption phenomenon under the excitation of a high-intensity green-light flash tube. Inspired by Maiman's observation, here we propose a new two-photon up-conversion charging (UCC) concept to effectively charge Cr3+-activated near-infrared persistent phosphors using low-energy, high-intensity visible-light laser diodes. As an example, we demonstrate that a low-energy 635 nm laser diode can produce persistent luminescence in the LiGa5O8:Cr3+ persistent phosphor at the same magnitude as that produced by high-energy 335 nm ultraviolet light from a xenon arc lamp. Moreover, the UCC appears to be a common phenomenon in persistent phosphors containing other UCC-enabling activators such as rare-earth Pr3+ ions and transition metal Mn2+ ions. The UCC technique offers a new way to study persistent luminescence and utilize persistent phosphors; for instance, in bioimaging it makes effective in vivo charging persistent optical probes using tissue-friendly visible light possible.
Phytochemical and Hepatoprotective study of Nymphaea nouchali in Experimental Rats

The primary objective of present study was to explore the hepatoprotective activity of Nymphaea nouchali flower extract against carbon tetrachloride (CCl4) induced liver necrosis. Nymphaea nouchali flowers were extracted with organic solvents like ethanol and n-hexane. These extracts were subjected to phytochemical studies. After the confirmation of flavonoids in the extracts, they were tested for in-vivo hepatoprotective activity. The study was carried out by taking female Wister rats in five groups, where each group consists of five rats. Biochemical and histological studies were carried out as a testimonial of hepatoprotective effect. Increased levels of biochemical tests like Albumin, direct bilirubin, indirect bilirubin, total bilirubin, serum glutamateO-methyl transferase (SGOT), serum glutamate pyruvate transferase(SGPT) and alkaline phosphate (ALP) provide an evidence of liver necrosis in CCl4 induced group. Pre-treatment with Nymphaea nouchali ethanolic extract (NNEE) showed a significant recovery effect equally as that of the standard drug (silymarin) when compared with Nymphaea nouchali n-hexane extract (NNHE). The hepatoprotective effect was statistically analyzed by ANOVA and was found to be significant (P<0.0001).

We will present some stochastic optimization algorithms such as Simulated Annealing for functions defined on discrete sets, and its generalisation to functions defined on more general sets. At the end, we will present the one-dimensional Adaptive Annealing method and we will test its preformance on functions with a lot of local minima.
1 B lymphocytes protect islet beta cells in diabetes prone NOD mice treated with imatinib

Imatinib (Gleevec) reverses type 1 diabetes (T1D) in NOD mice and is currently in clinical trials in individuals with recent-onset disease. While research has demonstrated that imatinib protects islet b cells from the harmful effects of ER stress, the role the immune system plays in its reversal of T1D has been less well understood, and specific cellular immune targets have not been identified. In this study, we demonstrate that B lymphocytes, an immune subset that normally drives diabetes pathology, are unexpectedly required for reversal of hyperglycemia in NOD mice treated with imatinib. In the presence of B lymphocytes, reversal was linked to an increase in serum insulin concentration, but not an increase in islet b cell mass or proliferation. However, improved b cell function was reflected by a partial recovery of MafA transcription factor expression, a sensitive marker of islet b cell stress that is important to adult b cell function. Imatinib treatment was found to increase the antioxidant capacity of B lymphocytes, improving reactive oxygen species (ROS) handling in NOD islets. This study reveals a novel mechanism through which imatinib enables B lymphocytes to orchestrate functional recovery of T1D b cells. Research Metabolism
The Impact of the Global Financial Crisis on the Economic Development in the Eurasian Region

This study presents an empirical analysis of the impact of the global financial crisis on the economic development of the Eurasian region. The region covers fifteen states of the former Soviet Union: Armenia, Azerbaijan, Belarus, Estonia, Georgia, Kazakhstan, Kyrgyz Republic, Latvia, Lithuania, Moldova, Russian Federation, Tajikistan, Turkmenistan, Ukraine, Uzbekistan. Emerging economies of estimated countries are highly attractive for foreign investors, who stimulate economic growth in the region. This paper particularly investigates the relationship between economic growth and international capital flows in the Eurasian region before and after the global financial crisis. Panel estimations using annual data for the period 1990-2014 are made applying the Generalized Method of Moments estimation technique for the dynamic panel data, developed by Hansen (1982). Empirical results reveal that the main determinant of the regions’ economic development is FDI inflow. This study finds evidence that after the global financial crisis, economic growth in the region becomes more responsive to capital flows compared to the pre-crisis period.
Confidence Intervals for Extreme Quantile Estimates using Extreme Value Theory

In this dissertation, we investigate the theory of order statistics and extreme value theory to construct confidence intervals for high quantile estimates. In an extensive series of simulation experiments, we compare both methods in terms of coverage properties, that is, the average length of computed confidence intervals, and the proportion of them which contain the true quantile.
Microphone Feature Extraction Classifier Decision Speaker Template Storage Logic 1 2 3 4 5 8 9 6 7

Over the past few years significant progress has been made in the field of presentation attack detection (PAD) for automatic speaker recognition (ASV). This includes the development of new speech corpora, standard evaluation protocols and advancements in front-end feature extraction and back-end classifiers. The use of standard databases and evaluation protocols has enabled for the first time the meaningful benchmarking of different PAD solutions. This chapter summarises the progress, with a focus on studies completed in the last three years. The article presents a summary of findings and lessons learned from two ASVspoof challenges, the first community-led benchmarking efforts.

NUMERICAL ANALYSIS OF INTERACTION NOISE BETWEEN MAIN ROTOR AND TAIL ROTOR OF HELICOPTER

Unsteady calculation of the interaction between tail-rotor and main-rotor wake of helicopter is conducted using an overlapped grid method. A moving overlapped grid system is used with three types of grid including rotor grid, inner background grid and outer background grid for helicopter flight simulation. The rotor grid, consisting of 2 blades for main-rotor and 4 blades for tail-rotor, communicates with inner/outer-background grids during unsteady computations. The Blade-Vortex Interaction (BVI) noise of main-rotor and tail-rotor noise are predicted using a combination method of an unsteady Euler code with an aeroacoustic code based on the Ffowcs-Williams and Hawkings formulation. The effect of tail-rotor onto mainrotor and the tail-rotor noise are studied for the helicopter operating conditions.

MINIMAL SPLITTING FIELDS FOR GROUP REPRESENTATIONS, II

Let Q denote the rationals and, for n a pasitive integer, let εn denote a primitive nth root of unity over Q. Let χ be the character afforded by a complex irreducible representation T of a finite group G of order n and let mρ(χ) denote the Schur index of χ over Q. In view of the famous theorem of R. Brauer that T is realizable in Q(εn), it is natural to ask how close to mQ(χ) is min[L: Q(χ)], where the minimum is taken over all subfields L of cyclotomic extensions of Q in which T is realizable. Our main result shows that the above minimum is not, in general, very close to mQ(χ).
