Cardiomyocyte differentiation with cyclic mechanical strain
Creators: name: Zhao, Eric Jiahua
Publisher: name: University of British Columbia
Year: 2015

description: The creation of cardiomyocytes from pluripotent stem cells has the potential to revolutionize the treatment of heart disease, the discovery and testing of drugs, and our understanding of human physiology. Thus far, differentiation protocols have mainly focused on recapitulating the biochemical signalling events of cardiac organogenesis, and the resulting cardiomyocytes exhibit a fetal-like phenotype. We postulated that cyclic mechanical strain can mimic the mechanical environment of the developing heart, and, when applied in conjunction to biochemical differentiation protocols, can increase the efficiency of differentiation and the maturity of the resulting cells. Using an induced pluripotent stem cell line derived from human fibroblasts, we derived spontaneously contracting cardiomyocytes via treatment with activin A and bone morphogenetic protein 4 (BMP4). We observed that differentiation of induced pluripotent stem cells to cardiomyocytes is sensitive to cyclic strain, with the application of 5% continuous cyclic strain at 1Hz having the effect of inhibiting spontaneous contractions and disrupting sarcomere formation.

description: Research shows, that the major issue in development of quality software is precise estimation. Further this estimation depends upon the degree of intricacy inherent in the software i.e. complexity. This paper attempts to empirically demonstrate the proposed complexity which is based on IEEE Requirement Engineering document. It is said that a high quality SRS is pre requisite for high quality software. Requirement Engineering document (SRS) is a specification for a particular software product, program or set of program that performs some certain functions for a specific environment. The various complexity measure given so far are based on Code and Cognitive metrics value of software, which are code based. So these metrics provide no leverage to the developer of the code. Considering the shortcoming of code based approaches, the proposed approach identifies complexity of software immediately after freezing the requirement in SDLC process. The proposed complexity measure compares well with established complexity measures. Finally the trend can be validated with the result of proposed measure. Ultimately, Requirement based complexity measure can be used to understand the complexity of proposed software much before the actual implementation of design thus saving on cost and manpower wastage.

description: Due to the rising awareness of privacy and security in machine learning applications, federated learning (FL) has received widespread attention and applied to several areas, e.g., intelligence healthcare systems, IoT-based industries, and smart cities. FL enables clients to train a global model collaboratively without accessing their local training data. However, the current FL schemes are vulnerable to adversarial attacks. Its architecture makes detecting and defending against malicious model updates difficult. In addition, most recent studies to detect FL from malicious updates while maintaining the model's privacy have not been sufficiently explored. This paper proposed blockchain-based federated learning with SMPC model verification against poisoning attacks for healthcare systems. First, we check the machine learning model from the FL participants through an encrypted inference process and remove the compromised model. Once the participants' local models have been verified, the models are sent to the blockchain node to be securely aggregated. We conducted several experiments with different medical datasets to evaluate our proposed framework.

description: The honeycomb-lattice cobaltate Na$_3$Co$_2$SbO$_6$ has recently been proposed to be a proximate Kitaev quantum spin liquid~(QSL) candidate. However, non-Kitaev terms in the Hamiltonian lead to a zigzag-type antiferromagnetic~(AFM) order at low temperatures. Here, we partially substitute magnetic Co$^{2+}$ with nonmagnetic Zn$^{2+}$ and investigate the chemical doping effect in tuning the magnetic ground states of Na$_3$Co$_{2-x}$Zn$_x$SbO$_6$. X-ray diffraction characterizations reveal no structural transition but quite tiny changes on the lattice parameters over our substitution range $0\leq x\leq0.4$. Magnetic susceptibility and specific heat results both show that AFM transition temperature is continuously suppressed with increasing Zn content $x$ and neither long-range magnetic order nor spin freezing is observed when $x\geq0.2$. More importantly, a linear term of the specific heat representing fermionic excitations is captured below 5~K in the magnetically disordered regime, as opposed to the $C_{\rm m}\propto T^3$ behavior expected for bosonic excitations in the AFM state. Based on the data above, we establish a magnetic phase diagram of Na$_3$Co$_{2-x}$Zn$_x$SbO$_6$. Our results indicate the presence of gapless fractional excitations in the samples with no magnetic order, evidencing a potential QSL state induced by doping in a Kitaev system.

description: We report the growth of an unstable shell-like gold structure around dihexagonal pyramidal CdSe nanocrystals in organic solution and the structural transformation to spherical domains by two means: i) electron beam irradiation (in situ) and (ii) addition of a strong reducing agent during synthesis. By varying the conditions of gold deposition, such as ligands present or the geometry of the CdSe nanocrystals, we were able to tune the gold domain size between 1.4 nm to 3.9 nm and gain important information on the role of surface chemistry in hetero nanoparticle synthesis and seed reactivity, both of which are crucial points regarding the chemical design of new materials for photocatalysis and optoelectronic applications.

description: Smart manufacturing systems involve a large number of interconnected devices resulting in massive data generation. Cloud computing technology has recently gained increasing attention in smart manufacturing systems for facilitating cost-effective service provisioning and massive data management. In a cloud-based manufacturing system, ensuring authorized access to the data is crucial. A cloud platform is operated under a single authority. Hence, a cloud platform is prone to a single point of failure and vulnerable to adversaries. An internal or external adversary can easily modify users' access to allow unauthorized users to access the data. This paper proposes a role-based access control to prevent modification attacks by leveraging blockchain and smart contracts in a cloud-based smart manufacturing system. The role-based access control is developed to determine users' roles and rights in smart contracts. The smart contracts are then deployed to the private blockchain network. We evaluate our solution by utilizing Ethereum private blockchain network to deploy the smart contract. The experimental results demonstrate the feasibility and evaluation of the proposed framework's performance.

description: Let $M$ be a smooth closed orientable surface. Let $F$ be the space of Morse functions on $M$, and $\mathbb{F}^1$ the space of framed Morse functions, both endowed with $C^\infty$-topology. The space $\mathbb{F}^0$ of special framed Morse functions is defined. We prove that the inclusion mapping $\mathbb{F}^0\hookrightarrow\mathbb{F}^1$ is a homotopy equivalence. In the case when at least $χ(M)+1$ critical points of each function of $F$ are labeled, homotopy equivalences $\mathbb{\widetilde K}\sim\widetilde{\cal M}$ and $F\sim\mathbb{F}^0\sim{\mathscr D}^0\times\mathbb{\widetilde K}$ are proved, where $\mathbb{\widetilde K}$ is the complex of framed Morse functions, $\widetilde{\cal M}\approx\mathbb{F}^1/{\mathscr D}^0$ is the universal moduli space of framed Morse functions, ${\mathscr D}^0$ is the group of self-diffeomorphisms of $M$ homotopic to the identity.

description: We investigate the structure of quantum correlations in an expanding Bose Einstein Condensate (BEC) through the analogue gravity framework. We consider both a 3+1 isotropically expanding BEC as well as the experimentally relevant case of an elongated, effectively 1+1 dimensional, expanding condensate. In this case we include the effects of inhomogeneities in the condensate, a feature rarely included in the analogue gravity literature. In both cases we link the BEC expansion to a simple model for an expanding spacetime and then study the correlation structure numerically and analytically (in suitable approximations). We also discuss the expected strength of such correlation patterns and experimentally feasible BEC systems in which these effects might be detected in the near future.

description: Low-field (<1T) magnetic resonance imaging (MRI) scanners remain in widespread use in low- and middle-income countries (LMICs) and are commonly used for some applications in higher income countries e.g. for small child patients with obesity, claustrophobia, implants, or tattoos. However, low-field MR images commonly have lower resolution and poorer contrast than images from high field (1.5T, 3T, and above). Here, we present Image Quality Transfer (IQT) to enhance low-field structural MRI by estimating from a low-field image the image we would have obtained from the same subject at high field. Our approach uses (i) a stochastic low-field image simulator as the forward model to capture uncertainty and variation in the contrast of low-field images corresponding to a particular high-field image, and (ii) an anisotropic U-Net variant specifically designed for the IQT inverse problem. We evaluate the proposed algorithm both in simulation and using multi-contrast (T1-weighted, T2-weighted, and fluid attenuated inversion recovery (FLAIR)) clinical low-field MRI data from an LMIC hospital. We show the efficacy of IQT in improving contrast and resolution of low-field MR images. We demonstrate that IQT-enhanced images have potential for enhancing visualisation of anatomical structures and pathological lesions of clinical relevance from the perspective of radiologists. IQT is proved to have capability of boosting the diagnostic value of low-field MRI, especially in low-resource settings.

description: Introduction: The emergency care system (ECS) is a critical component of national health care systems and remains an underdeveloped aspect of health care in many lowand middle-income countries of the world. Goal of the study: to analyze the effectiveness of the new continuing emergency care education model introduction in the Kyrgyz Republic. Materials and methods: A comprehensive retrospective analysis of preclinical and clinical training results was carried out based on the newly introduced training model. To assess the initial and final level of the course participants’ knowledge, form-based tests were used. Practical skills were evaluated using patient simulators and simulation-based clinical scenarios, and the effectiveness and quality of the training courses were evaluated. The final evaluation of the theoretical and practical training parts is presented based on the monitoring of the work of medical workers with repeated clinical training in the workplace. The study findings: A conceptual model of emergency medical care training and new curricula and materials were developed by adapting the international recommendations and standards to the country’s context, practical training was provided based on innovative manikins with different clinical scenarios close to real-life situations. All health care workers have a high knowledge growth rate and practical skills improvement after the training. The indicator of the knowledge growth rate (KGR) for doctors was 62,7%, for nurses and paramedics it was 84,8% and 78,1% respectively. During the monitoring and evaluation of the EMS workers after the training, it was found that they had acquired the necessary knowledge and practical skills at a high level. Conclusion: A conceptual emergency medical care training model for emergency medical service specialists has been developed, which significantly increases the effectiveness of training and subsequently has become a long-term and sustainable system.

description: We present the results of a Hubble Space Telescope (HST) ACS and WFPC2 study of dwarf galaxies in the nearby Perseus Cluster, down to M_V = -12, spanning the core and outer regions of this cluster. We examine how properties such as the colour magnitude relation, structure and morphology are affected by environment for the lowest mass galaxies. The low masses of dwarf galaxies allow us to determine their environmentally driven based galaxy evolution, the effects of which are harder to examine in massive galaxies. The structures of our dwarfs in both the core and outer regions of the cluster are quantified using the concentration, asymmetry and clumpiness (CAS) parameters. We find that, on average, dwarfs in the outer regions of Perseus are more disturbed than those in the cluster core, with higher asymmetries and clumpier light distributions. We measure the (V-I)_0 colours of the dEs, and find that dwarfs in both the inner and outer regions of the cluster lie on the same colour magnitude relation. Based on these results, we infer that the disturbed dwarfs in the cluster outskirts are likely "transition dwarfs", with their colours transforming before their structures. Finally, we infer from the smoothness of the cluster core population that dwarfs in the inner regions of the cluster must be highly dark matter dominated to prevent their disruption by the cluster potential. We derive a new method to determine the minimum mass the dwarfs must have to prevent this disruption without the need for resolved spectroscopy, and determine their mass-to-light ratios. At their orbit pericentre, dwarfs in the core of Perseus require mass-to-light ratios between 1 and 120 to prevent their disruption, comparable to those found for the Local Group dSphs.

description: Disorders of glutaminergic neurotransmitters play an essential role in the manifestations of symptoms and progression of neurodegenerative dementia, especially with the participation of NMDA receptors. Memantine is an NMDA receptor antagonist that blocks the effects of abnormally elevated glutamate levels, which can lead to neuronal dysfunction and neurodegeneration. Memantine is widely used in the treatment of Alzheimer's disease. Also, experiments have shown the protective effect of memantine in damage to hippocampal cells by β-amyloid. This study aimed to investigate the possible direct positive effect of memantine on learning and memory processes in young rats. In the experiments, we used the behavioral reactions of young rats in the active avoidance test. We found that memantine is well-tolerated, improves learning ability, and motivational behavior characteristics reduce anxiety and fear, which in general can be described as an adaptive-stimulating effect.

description: Generally, crowd datasets can be collected or generated from real or synthetic sources. Real data is generated by using infrastructure-based sensors (such as static cameras or other sensors). The use of simulation tools can significantly reduce the time required to generate scenario-specific crowd datasets, facilitate data-driven research, and next build functional machine learning models. The main goal of this work was to develop an extension of crowd simulation (named CrowdSim2) and prove its usability in the application of people-tracking algorithms. The simulator is developed using the very popular Unity 3D engine with particular emphasis on the aspects of realism in the environment, weather conditions, traffic, and the movement and models of individual agents. Finally, three methods of tracking were used to validate generated dataset: IOU-Tracker, Deep-Sort, and Deep-TAMA.

description: We study the exciton states in the symmetrically biased dice model, the electronic structures of which have an isolated flat band between two dispersive bands. At 1/3 or 2/3 filling, the model describes a two-dimensional semiconductor with the band edge at two degenerate valleys. Because of qualitative changes in the eigenvectors resulting from the bias term, the interband transition between the flat band and a dispersive band is valley contrasting under circularly polarized light. In terms of an effective-mass model and a realistic electron-hole interaction, we numerically calculate the spectrum and wave functions of the intravalley excitons, which are treated as Wannier-Mott excitons. We also discuss the fine structures of the exciton spectrum induced by the intravalley and intervalley exchange interactions. The symmetrically biased dice model thereby proves to be a new platform for valley-contrasting optoelectronics.

description: Hemodialysis and peritoneal dialysis are currently the main methods of renal replacement therapy. According to statistics, about 80% of all patients with chronic kidney disease V dialysis stage in the world receive this type of treatment . An important aspect in the management of this category of patients is not only the proper dialysis program, timely detection and correction of developing complications, but also the survival of patients. It often depends on the severity of protein-energy deficiency and sarcopenia associated with CKD and dialysis . However, sarcopenia is one of the causes of increased cardiovascular mortality and occurs in 37% of patients with CKD 5D . In this regard, identifying the causes of loss of muscle mass and strength in this category of patients is prognostically important.

We demonstrate linear driving of the mirror using influence functions, measured with a Fizeau interferometer, by producing the first 36 Zernikes polynomials. Based on our measurements, we predict achievable mean PV wavefront amplitudes of up to 30 μm having RMS residuals of λ/10 at 632.8 nm. Linear combination of Zernikes and over-time repeatability are also demonstrated.

Quantitative analysis of factors influencing post-earthquake decisions on concrete buildings in Christchurch, New Zealand

Publisher: name: University of British Columbia
Year: 2015

description: The 2010-2011 Canterbury Earthquake Sequence resulted in unprecedented losses including 185 casualties, an estimated $NZ 40 billion cost of rebuild, and the demolition of 60% of reinforced concrete buildings in the Christchurch Central Business District (CBD). Intriguingly, demolition rate is unexpectedly high compared to the reported damages. This study thus sought to explore factors influencing the post-earthquake decisions on buildings (demolition or repair). Focusing the study on multi-storey reinforced concrete buildings in the Christchurch CBD, information on building characteristics, assessed post-earthquake damage, and post-earthquake decision (demolish or repair) for 223 buildings was collected. Data were obtained on approximately 88% of the 3-storey and higher reinforced concrete buildings within the CBD, or approximately 34% of all reinforced concrete buildings in the CBD. The study of descriptive statistics and trends of the database confirms that a significant portion of repairable buildings were demolished. Logistic regression models were developed based on the collected empirical data. From the significance testing, the assessed damage, occupancy type, heritage status, number of floors, and construction year were identified as variables influencing the building-demolition decision. Their effects on the post-earthquake decisions were approximated, and the resulting likelihood of building demolition was estimated for buildings with different attributes. From personal interviews with 9 building owners, 9 building developers and investors, 5 insurance sector representatives, and 4 local engineers and government authority personnel, it was learned that the local context, such as insurance policy and changes in local legislation, also played a significant role in the decision-making process. As the first quantitative study that explores the effects of factors on the post-earthquake building demolition decisions, the findings of this study indicates that the damage is not the only factor affecting the post-earthquake decisions on buildings. Incorporation of all influential factors in the probability-of-demolition function would provide better means of estimating expected total loss by considering decision outcome scenarios and associated costs. This would benefit the decision makers with comprehensive and valuable information concerning seismic risk management and strategy. Limitations on this study are discussed and similar studies are suggested reflecting the locality of different communities with seismic risk.

description: We study static superfluid properties of alkali-earth-like Fermi atomic systems in the presence of orbital Feshbach resonance. Using a two-band description of the ground state and excited state and a mean-field approximation of the intra-band atomic pairing, we investigate the phase transitions and crossover between BCS and Bose-Einstein-condensate (BEC) superfluidity. At zero temperature, we find exact BCS analytical solutions for the mean-field gap equations and number equations. Using these exact solutions, we calculate various static properties, such as superfluid order parameters, chemical potentials, density variations, density profiles, correlation and coherence lengths, ground-state energy, and Tan's contact density across the entire BCS-BEC crossover region. We anticipate that our closed-form analytical results can be used as a benchmark for future experimental and theoretical investigations and will have an impact on the current understanding of two-band superconductors such as MgB$_2$.

Music as a delight of god and men : absolutism, genre, and instrumental music in seventeenth-century Salzburg
Creators: name: Beck, Kimberly Jean
Publisher: name: University of British Columbia
Year: 2015

description: The seventeenth century was an age of absolutist ideology during which many European princes took upon themselves trappings of both religious and secular authority. Composers in the service of absolutist patrons were compelled to provide music that could move easily between sacred and secular venues and represent both facets of the prince’s power. Contemporary conceptions of musical classification exhibit this porous threshold between religious and profane genres and performance spaces. In this dissertation, I show how a flexible conception of musical genre—one in which traditionally sacred and secular idioms were blended in diverse ways—illustrated the dual nature of the authority of Salzburg’s absolutist Prince Archbishop. The diverse oeuvre of Salzburg’s composers calls into question the very definition of musical genre in the period. While a modern conception of fixed musical genres is manifest in theoretical treatises of the time, musical evidence suggests that well-defined genre classifications did not practically exist in the seventeenth century. Rather, composers took a malleable approach to genre, often blending different texts, musical forms, and styles to craft musical compositions latent with meanings that encompass several genres. In the first chapter, I consider genre as described in contemporary treatises and argue that modern literary genre theory provides a useful lens for the study of genre in the period. Chapter 2 turns to the sacred repertoire of Salzburg, which in its variety of centonized texts, timbres, and instrumentations deviates from the stylistic norms of liturgical genres. In Chapter 3 I explore the representational capabilities of the large-scale works performed during spectacles that were symbolic of the power and piety of Salzburg’s Prince Archbishop. Salzburg’s instrumental ensemble sonatas, explored in Chapter 4, reveal two particular uses for the term “sonata” and point to the genre as a site of both representation and innovation. The final chapter considers the solo sonata as a devotional aid in the context of cyclic spiritual exercises in Salzburg, where music transcended the limitations of genre to move between notionally sacred and secular performance spaces to represent the piety and power of the Prince Archbishop.

description: We prove two dichotomy theorems about sequences of operators into $L_1$ given by random matrices. In the second theorem we assume that the entries of each random matrix form a sequence of independent, symmetric random variables. Then the corresponding sequence of operators either uniformly factor the identity operators on $\ell_1^k$ $(k\in\mathbb N$) or uniformly approximately factor through $\mathrm{c}_0$. The first theorem has a slightly weaker conclusion still related to factorization properties but makes no assumption on the random matrices. Indeed, it applies to operators defined on an arbitrary sequence of Banach spaces. These results provide information on the closed ideal structure of the Banach algebra of all operators on the space $\big(\bigoplus_{n=1}^\infty\ell_1^n \big)_{\mathrm{c}_0}$.

description: The Acceleration Grid Power Supply of the MITICA test facility in Padova (Italy) is currently under commissioning. The power conversion system, the DC generator, and the High Voltage equipment have been individually commissioned, whereas the integration tests are ongoing. It is a challenging process due to the unconventional application, to the variety of different electrical technologies involved and to the complexity of the interfaces. During the integrated tests of the power supplies the achievement of 700kV stable operation has been demonstrated for the first time in a Neutral Beam Injector, but an unexpected event occurred, most likely a breakdown in the HV part, which resulted in a fault of the DC generator. A subsequent test using an auxiliary power supply was performed to check the voltage withstanding capability of the HV plant, but another breakdown occurred at around 1MV. This paper describes the activity performed to identify the location of the breakdowns affecting the integrated tests. A test campaign has been devised with increased diagnostic capabilities and specific strategy conceived to trigger intentional breakdowns in specific locations and collect measurement patterns for different cases. The results of the campaign will be presented and the current understanding of the issue will be described, with a view on future tests and further improvements of diagnostics.

description: Mass caving systems require significant capital expenditure and long-term commitment of resources before production commences. Cave mining projects are confronted with numerous challenges in maintaining their construction schedule expectations. Any delay in construction impacts on the production schedule and, in turn, reduces the project value. In order to increase the expected economic value, the construction schedule needs to be accelerated through strategic flexibilities. It is hypothesized that construction acceleration (crashing) can be achieved by prioritizing the construction schedule or changing the construction strategy. This thesis seeks to expand current knowledge on three interrelated domains for decision making in engineering systems—(i) recognition, (ii) modeling and (iii) pricing of flexibility in cave mining construction. An objective of this study was to provide state-of-the-art project formulation techniques employed in planning that can be used to support decision-making processes in cave mining systems. The first domain requires identifying construction strategies that allow the mine management to implement construction crashing in multiple heading development. Three independent and interrelated flexibilities are considered. The second domain requires development of a methodology suitable for investigating and forecasting through modeling the development and construction rates enabling implementation of flexible strategies. A method capable of modeling the development and construction processes with respect to the advance undercut mining strategy is developed, which integrates the geotechnical and equipment-related uncertainties, using the framework of discrete event simulation. Several models are developed to investigate the impact of implementing these flexibilities on the development and construction rates. The results from the flexible models compared to the benchmark models confirmed that significant construction benefits can be achieved. The third domain requires development of an algorithm suitable for evaluating the cost of implementing a construction crashing option that can accommodate delays. A method that is able to respond to schedule uncertainties in construction projects by incorporating the decision-making strategy of project crashing into the budget, including the cost contingency valuation, is developed using the framework of real options and Monte Carlo simulation from a contractor’s perspective. The results indicated that significant change in costs stems from the variation in risk perceptions and confidence levels.

description: Since 1992, a new Chinese innovation system has been emerging in terms of university-industry-government relations. In recent years, science parks, incubators, and high-tech development zones have been provided with strong incentives. The commitment of the Chinese government to the further introduction of a market economy has been elaborated with a focus on the knowledge-base. The model of institutional adjustments has been replaced with systemic and evolutionary thinking about niche development and human resource management. Government interventions remain important for interfacing knowledge-based developments with those on the market. For example, new legislation on issues of "intellectual property rights" is crucial to the absorption of venture capital into these developments.

description: The Duan-Lukin-Cirac-Zoller (DLCZ) scheme is a potential method to establish remote entanglements and realize large-scale quantum networks. Here we propose a DLCZ-like scheme based on the noiseless photon echo in rare-earth ion-doped crystals. Correlated photon pairs with a controllable delay can be created by the direct optical rephasing. Theoretical analysis indicates that the protocol is efficient in the low-optical-depth regime. This protocol could be feasibly implemented to establish long-lived quantum correlations between a photon and a spin-wave excitation in rare-earth ion-doped crystals.

description: Quasi-periodic responses composed of multiple base frequencies widely exist in science and engineering problems. The multiple harmonic balance (MHB) method is one of the most commonly used approaches for such problems. However, it is limited by low-order estimations due to complex symbolic operations in practical uses. Many variants have been developed to improve the MHB method, among which the time domain MHB-like methods are regarded as crucial improvements because of their high efficiency and simple derivation. But there is still one main drawback remaining to be addressed. The time domain MHB-like methods negatively suffer from non-physical solutions, which have been shown to be caused by aliasing (mixtures of the high-order into the low-order harmonics). Inspired by the collocation-based harmonic balancing framework recently established by our group, we herein propose a reconstruction multiple harmonic balance (RMHB) method to reconstruct the conventional MHB method using discrete time domain collocations. Our study shows that the relation between the MHB and time domain MHB-like methods is determined by an aliasing matrix, which is non-zero when aliasing occurs. On this basis, a conditional equivalence is established to form the RMHB method. Three numerical examples demonstrate that this new method is more robust and efficient than the state-of-the-art methods.

gender differences of student`s satisfaction

description: Article shows investigation of medical university student’s satisfaction with the online learning mode in strict quarantine, depending of the respondents’ gender by anonymous questionnaire. The questionnaire offered to students contained questions about the organization of the educational process in the online format with the remote technologies, the effectiveness of this method of obtaining knowledge, and other problematic issues. The survey was conducted twice: at the beginning of quarantine measures in March 2020 and the second survey was conducted at the end of the spring semester 2019-2020 academic year in May-June 2020. Female students more often than male students, at the start of distance learning express dissatisfaction exclusively with the online format of the educational process, but the increasing rate of such dissatisfaction in men is higher. At the initial and final questionnaire female students are twice as likely as male students recognize to increase the amount of processed educational material in the context of distance education, which emphasizes the greater diligence of women in learning and is confirmed by the probably greater influence of personal disorganization on the learning process in the men cohort. In the process of distance learning, the risk of problems with Internet communication is probably reduced among female students, but the risk of negative impact of their own disorganization on the educational process is slightly increased.

description: We present an application of Artificial Intelligence techniques to the field of Information Security. The problem of remote Operating System (OS) Detection, also called OS Fingerprinting, is a crucial step of the penetration testing process, since the attacker (hacker or security professional) needs to know the OS of the target host in order to choose the exploits that he will use. OS Detection is accomplished by passively sniffing network packets and actively sending test packets to the target host, to study specific variations in the host responses revealing information about its operating system. The first fingerprinting implementations were based on the analysis of differences between TCP/IP stack implementations. The next generation focused the analysis on application layer data such as the DCE RPC endpoint information. Even though more information was analyzed, some variation of the "best fit" algorithm was still used to interpret this new information. Our new approach involves an analysis of the composition of the information collected during the OS identification process to identify key elements and their relations. To implement this approach, we have developed tools using Neural Networks and techniques from the field of Statistics. These tools have been successfully integrated in a commercial software (Core Impact).

description: A canonical approach to Cherenkov radiation in the presence of a magnetodielectric medium is presented in classical, nonrelativistic and relativistic quantum regimes. The equations of motion for the canonical variables are solved explicitly for both positive and negative times. Maxwell and related constitute equations are obtained. In the large-time limit, the vector potential operator is found and expressed in terms of the medium operators. The energy loss of a charged particle, emitted in the form of radiation, in finite temperature is calculated. A Dirac equation concerning the relativistic motion of the particle in presence of the magnetodielectric medium is derived and the relativistic Cherenkov radiation at zero and finite temperature is investigated. Finally, it is shown that the Cherenkov radiation in nonrelativistic and relativistic quantum regimes, unlike its classical counterpart, introduces automatically a cutoff for higher frequencies beyond which the power of radiation emission is zero.
