description: One of the most important practices of cybercrime investigations is to search a network traffic history for an excerpt of traffic, such as the disclosed information of an organization or a worm signature. In post-mortem investigations, criminals and targets are detected by attributing the excerpt to payloads of traffic flows. Since it is impossible to store the high volume of data related to long-term traffic history, payload attribution systems (PAS) based on storing a compact digest of traffic using Bloom filters have been presented in the literature. In these systems, querying the stored digest for an excerpt results in a low number of suspects instead of certain criminals. In this paper, we present a different PAS which is based on simple and widespread digital signal processing techniques. Our traffic digesting scheme has been inspired by DSP-based compression algorithms. The proposed payload attribution system, named DSPAS, not only results in a low false positive rate but also outperforms previous schemes in response to wildcard queries which are essentially applicable for complex excerpts such as the signature of polymorphic worms. Our theoretical analysis and practical evaluations show that DSPAS results in a significantly lower false positive rate and also a lower processing time for wildcard queries in comparison to previous works. Moreover, our PAS can prevent a malicious insider from evading the PAS by its ability to find strings similar to a queried excerpt.

description: Experimental observations of droplet size sustained oscillations are reported in a two-phase flow between a lamellar and a sponge phase. Under shear flow, this system presents two different steady states made of monodisperse multilamellar droplets, separated by a shear-thinning transition. At low and high shear rates, the droplet size results from a balance between surface tension and viscous stress whereas for intermediate shear rates, it becomes a periodic function of time. A possible mechanism for such kind of oscillations is discussed.

description: Here, we present results from a systematic study on cleaning of oily deposits from solid surfaces (porcelain and stainless steel) by solutions of fatty acid sulfonated methyl esters (SME), sodium salts. The zwitterionic dodecyldimethylamine oxide (DDAO) has been used as a cosurfactant. As representatives of the vegetable and mineral oils, sunflower seed oil and light mineral oil have been used. The process of oil drop detachment from the solid substrates (roll-up mechanism) has been monitored. In the case of porcelain, excellent cleaning of oil is achieved by mixed solutions of SME and DDAO. In the case of stainless steel, excellent cleaning (superior than that by linear alkylbenzene sulfonate and sodium lauryl ether sulfate) is provided by binary and ternary mixtures of SMEs, which may contain also DDAO. For the studied systems, the good cleaning correlates neither with the oil/water interfacial tension, nor with the surfactant chainlength and headgroup type. The data imply that governing factors might be the thickness and morphology of admicelle layers formed on the solid/water interface. The results indicate that the SME mixtures represent a promising system for formulations in house-hold detergency, having in mind also other useful properties of SME, such as biodegradability, skin compatibility and hard water tolerance.

description: Building on Evans function techniques developed to study the stability of viscous shocks, we examine the stability of viscous strong detonation wave solutions of the reacting Navier-Stokes equations. The primary result, following the work of Alexander, Gardner & Jones and Gardner & Zumbrun, is the calculation of a stability index whose sign determines a necessary condition for spectral stability. We show that for an ideal gas this index can be evaluated in the ZND limit of vanishing dissipative effects. Moreover, when the heat of reaction is sufficiently small, we prove that strong detonations are spectrally stable provided the underlying shock is stable. Finally, for completeness, the stability index calculations for the nonreacting Navier-Stokes equations are included

description: During a search for X-ray transients in the XMM-Newton archive within the EXTraS project, we discovered a new X-ray source that is detected only during a ~5 min interval of a ~21 h-long observation performed on 2011 June 21 (EXMM 023135.0-603743, probability of a random Poissonian fluctuation: ~$1.4\times10^{-27}$). With dedicated follow-up observations, we found that its position is consistent with a star-forming galaxy (SFR = 1-2 $M_\odot$ yr$^{-1}$) at redshift $z=0.092\pm0.003$ ($d=435\pm15$ Mpc). At this redshift, the energy released during the transient event was $2.8\times10^{46}$ erg in the 0.3-10 keV energy band (in the source rest frame). The luminosity of the transient, together with its spectral and timing properties, make EXMM 023135.0-603743 a gripping analog to the X-ray transient associated to SN 2008D, which was discovered during a Swift/XRT observation of the nearby ($d=27$ Mpc) supernova-rich galaxy NGC 2770. We interpret the XMM-Newton event as a supernova shock break-out or an early cocoon, and show that our serendipitous discovery is compatible with the rate of core-collapse supernovae derived from optical observations and much higher than that of tidal disruption events.

description: The determination of the mechanical properties of soils containing particles larger than the allowable size of standard laboratory equipments is complex. It is indeed necessary to remove the coarsest fraction to carry out the tests. This scalping poses a problem of reliability of the results at the scale of the structure. Parallel gradation is the method commonly used for estimating the shear strength of heterogeneous granular soils from tests on their finer fraction. However, the effect of high fines content on the estimation of shear strength by this method is not well understood. The results of this study showed that the parallel gradation method could predict the friction angle of the initial soil with high fines content when the modelled soil had a similar skeleton as the initial soil. However, the cohesion of the initial soil was overestimated.
title: The perception of students about school bullying and how it affects academic performance in Cameroon

description: Many students in secondary schools in Cameroon in general and the North West and South West region get into schools to pursue an academic career. The educational journey is rich with several goals but most at times challenging with ups and downs as regards bullying in the school environment. This thesis research explored school bullying amongst high school students, their perspectives, and their effects on academic performance. Data was collected from over 30 participants, of whom 24 were students of upper sixth classes, and 6 were teachers in the Northwest and Southwest regions of Cameroon in secondary schools. All interviews were through WhatsApp with questioning, and it was found that most students go through kinds of bullying in secondary schools, and most often do not let anyone know about it. The findings showed that school bullying still exists in most schools and influences student’s academic performance and school attendance. It was acknowledged that most students experienced bullying in their classes, and some students reported cases of bullying to their teachers. Bullying still exists and continues to affect the academic achievements of most students in Cameroon.

description: Migration of cells can be characterized by two, prototypical types of motion: individual and collective migration. We propose a statistical-inference approach designed to detect the presence of cell-cell interactions that give rise to collective behaviors in cell-motility experiments. Such inference method has been first successfully tested on synthetic motional data, and then applied to two experiments. In the first experiment, cell migrate in a wound-healing model: when applied to this experiment, the inference method predicts the existence of cell-cell interactions, correctly mirroring the strong intercellular contacts which are present in the experiment. In the second experiment, dendritic cells migrate in a chemokine gradient. Our inference analysis does not provide evidence for interactions, indicating that cells migrate by sensing independently the chemokine source. According to this prediction, we speculate that mature dendritic cells disregard inter-cellular signals that could otherwise delay their arrival to lymph vessels.

description: The computation of the order of Frobenius action on the $\ell$-torsion is a part of Schoof-Elkies-Atkin algorithm for point counting on an elliptic curve $E$ over a finite field $\mathbb{F}_q$. The idea of Schoof's algorithm is to compute the trace of Frobenius $t$ modulo primes $\ell$ and restore it by the Chinese remainder theorem. Atkin's improvement consists of computing the order $r$ of the Frobenius action on $E[\ell]$ and of restricting the number $t \pmod{\ell}$ to enumerate by using the formula $t^2 \equiv q (ζ+ ζ^{-1})^2 \pmod{\ell}$. Here $ζ$ is a primitive $r$-th root of unity. In this paper, we generalize Atkin's formula to the general case of abelian variety of dimension $g$. Classically, finding of the order $r$ involves expensive computation of modular polynomials. We study the distribution of the Frobenius orders in case of abelian surfaces and $q \equiv 1 \pmod{\ell}$ in order to replace these expensive computations by probabilistic algorithms.

description: We present deep spectrophotometry of 18 HII regions in the nearby massive spiral galaxies M101 and M31. We have obtained direct determinations of electron temperature in all the nebulae. We detect the CII 4267 line in several HII regions, permitting to derive the radial gradient of C/H in both galaxies. We also determine the radial gradients of O/H, N/O, Ne/O, S/O, Cl/O and Ar/O ratios. As in other spiral galaxies, the C/H gradients are steeper than those of O/H producing negative slopes of the C/O gradient. The scatter of the abundances of O with respect to the gradient fittings do not support the presence of significant chemical inhomogeneities across the discs of the galaxies, especially in the case of M101. We find trends in the S/O, Cl/O and Ar/O ratios as a function of O/H in M101 that can be reduced using Te indicators different from the standard ones for calculating some ionic abundances. The distribution of the N/O ratio with respect to O/H is rather flat in M31, similarly to previous findings for the MilkyWay. Using the disc effective radius, Re, as a normalization parameter for comparing gradients, we find that the latest estimates of Re for the Milky Way provide an excess of metallicity in apparent contradiction with the mass-metallicity relation; a value about two times larger might solve the problem. Finally, using different abundance ratios diagrams we find that the enrichment timescales of C and N result to be fairly similar despite their different nucleosynthetic origin.

A dynamical instability of the Fermi sea against association into molecules initiates the conversion. The model qualitatively reproduces several experimental observations {[Regal et al., Nature {\bf 424}, 47 (2003)]}. We predict that the initial temperature of the Fermi gas sets the limit for the efficiency of atom-molecule conversion.

Pinning and Sliding of Driven Elastic Systems: from Domain Walls to Charge Density Waves

Year: 2003
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: The review is devoted to the theory of collective and it local pinning effects in various disordered non-linear driven systems. Although the emphasis is put on charge and spin density waves and magnetic domain walls, the theory has also applications to flux lines and lattices thereof, dislocation lines, adsorbed mono-layers and related systems. In the first part we focus on the theory of the collective pinning which includes the equilibrium properties of elastic systems with frozen-in disorder as well as the features close to the dynamic depinning transition enforced by an external driving force and at finite temperatures. Thermal fluctuations smear out this transition and allow for a creep motion of the elastic objects even at small forces. An ac-driving force also destroys the sharp transition which is replaced by a velocity hysteresis. The second part is devoted to the local pinning picture and its applications. Inclusion of plastic deformations results in a rich cross-over behavior of the force-velocity relation as well as of the frequency dependence of the dynamic response. The local pinning recovers and exploits new elements of the energy landscape such as termination points of metastable branches or irreversibility of other ones related to generation of topological defects in the course of sliding. It also gives access to the quantum creep described as a tunneling between retarded and advanced configurations.

description: PhD thesis: Ciliates have a pivotal role in the ecology of marine systems, as they are an important trophic link between the microbial loop and the metazoan grazers. Many planktonic ciliates retain functional chloroplasts from the photosyntetic prey that they ingest. This enables them to photosynthesize and thereby being mixotrophs. While some species express a selective behaviour towards specific prey types from which they acquire chloroplasts, the majority of species among the oligotrich ciliates can acquire chloroplasts from different algal types and are defined as prey generalists. The focus on this thesis was on the ecology and physiology of these organisms based on laboratory experiments on cultures of Strombidium spp. In addition to this, a field survey was carried out on four Greenlandic fjords that receives high amount of glacier fluor to assess the role of mixotrophs in these systems.

description: JWST has discovered a large population of Active Galactic Nuclei (AGN) at high redshift. Many of these newly discovered AGN have broad permitted lines (typically H$α$), but are extremely weak in the X-rays. Here we present the NIRSpec spectrum of the most extreme of these objects, GN-28074, an AGN at $z=2.26$ with prominent Balmer, Paschen and \HeI broad lines, and with the highest limit on the bolometric to X-ray luminosity ratio among all spectroscopically confirmed AGN in GOODS. This source is also characterized by a mid-IR excess, most likely associated with the AGN torus' hot dust. The high bolometric luminosity and moderate redshift of this AGN allow us to explore its properties more in depth relative to other JWST-discovered AGN. The NIRSpec spectrum reveals prominent, slightly blueshifted absorption of H$α$, H$β$ and \HeI$λ$10830. The Balmer absorption lines require gas with densities of $n_{\rm H}> 10^8~{\rm cm}^{-3}$, inconsistent with an ISM origin, but fully consistent with clouds in the Broad Line Region (BLR). This finding suggests that at least part of the X-ray weakness is due to high (Compton thick) X-ray absorption by (dust-free) clouds in the BLR, or in its outer, slowly outflowing regions. GN-28074 is also extremely radio-weak. The radio weakness can also be explained in terms of absorption, as the inferred density of the clouds responsible for H$α$ absorption makes them optically thick to radio emission through free-free absorption. Alternatively, in this and other JWST-discovered AGN, the nuclear magnetic field may have not developed properly yet, resulting both in intrinsically weak radio emission and also lack of hot corona, hence intrinsic X-ray weakness. Finally, we show that recently proposed scenarios, invoking hyper-dense and ultra-metal-poor outflows or Raman scattering to explain the broad H$α$, are completely ruled out.

description: In this paper, we design a hybrid controller that globally exponentially stabilizes a system evolving on the n-dimensional sphere, denoted by Sn. This hybrid controller is induced by a synergistic collection of potential functions on Sn. We propose a particular construction of this class of functions that generates flows along geodesics of the sphere, providing convergence to the desired reference with minimal path length. We show that the proposed strategy is suitable to the exponential stabilization of a quadrotor vehicle.
The Effects of Non-aerobic Exercise on Cognitive Function in Older Adults

description: Cognitive decline among older adults is a major health care concern. Over 24 million people currently live with dementia worldwide, causing it to be the leading cause of disability in people over 60, with annual costs of 100 billion dollars in the U.S.A. Despite a lack of evidence supporting the use of pharmacological treatments for preventing or slowing the progression of Alzheimer's disease (AD) (the most common form of dementia), there are three drugs that are commonly prescribed for mild to moderate AD. There is currently no known cure for dementia. However, since there is a strong association between the increase in physical inactivity and the emergence of modern chronic diseases, physical activity has been widely promoted as a strategy for healthy aging. Physical activity provides clear benefits for cognition among older adults and lowers the risk of cognitive impairment and dementia. It reduces brain tissue loss, increases brain volume, and protects and enhances CNS integrity. It also promotes brain vascularization, neurogenesis, functional changes in neuronal structure, and neuronal resistance to injury. Finally, it enhances several neurotransmitter systems in the brain, including dopamine,serotonin, and acetylcholine. It is also believed that exercise activates molecular and cellular cascades that support and maintain brain plasticity. For example, exercise-induced increases of brain-derived neurotrophic factor (BDNF) and insulin-like growth factor-1 (IGF-1) are believed to play important roles in mediating the effects of exercise on brain health and performance, while exercise-induced reductions in serum homocysteine may play a role in reducing cognitive impairment. Most studies to date have focused on aerobic-based exercise interventions, but it has been suggested that non-aerobic exercise may also benefit cognition. While non-aerobic exercise may not provide an easy fix to enhance brain health and cognition across the life span, there is evidence to suggest that it may be an effective means available to improve mental and physical health, without the side effects of many pharmacological treatments. If found to have a positive effect on cognition, non-aerobic exercise based interventions may provide clinicians with a variety of alternative treatment options. Thus, a systemic review investigating the effects of non-aerobic exercise on cognitive function in older adults is warranted. MPT Systematic Reviews and Research Projects.

description: We introduce the boolean convolution for probability measures on the unit circle. Roughly speaking, it describes the distribution of the product of two boolean independent unitary random variables. We find an analogue of the characteristic function and determine all infinitely divisible probability measures on the unit circle for the boolean convolution.

Großprojekte, vor allem im Verkehrsbereich, stoßen zunehmend auf Widerstand. Gründe sind oft Lärm, Umweltbelastungen, intransparente Planungsprozesse und ganz besonders die Informationsaufbereitung und -vermittlung. Diese Arbeit untersucht, wie digitale Partizipationsformate in der Verkehrsplanung zur besseren Information und Einbindung der Bürgerinnen und Bürger beitragen können. Der Fokus liegt auf mobiler Partizipation und der Entwicklung von Mockups (App-Entwurf), die die Partizipation von Bürgerinnen und Bürgern effizienter gestalten soll. Eine Fallstudie zeigt altersabhängige Vorlieben zwischen analogen und digitalen Formaten. Die Analyse bestehender Apps und das Testen von Prototypen zeigen, dass mobile Formate durch schnelle und klare Informationsvermittlung zur aktiven Partizipation motivieren.

description: A lattice model of RNA denaturation which fully accounts for the excluded volume effects among nucleotides is proposed. A numerical study shows that interactions forming pseudoknots must be included in order to get a sharp continuous transition. Otherwise a smooth crossover occurs from the swollen linear polymer behavior to highly ramified, almost compact conformations with secondary structures. In the latter scenario, which is appropriate when these structures are much more stable than pseudoknot links, probability distributions for the lengths of both loops and main branches obey scaling with nonclassical exponents.

description: The Monte Carlo generator PPROPHECY4F provides a PROPer description of the Higgs dECaY into 4 Fermions within the Standard Model, the Standard Model with a fourth fermion generation, a simple Higgs-singlet extension of the Standard Model, and the Two-Higgs-Doublet Model. The fully differential predictions include the full QCD and electroweak next-to-leading-order corrections, all interference contributions between different WW/ZZ channels, and all off-shell effects of intermediate W/Z bosons. PPROPHECY4F computes the inclusive partial decay widths and allows for the computation of binned differential distributions of the decay products. For leptonic final states also unweighted events are provided.

description: We extend the most recent orbital and absolute magnitude Near Earth Object (NEO) model (Granvik et al., 2018) to provide a statistical description of NEO geometric albedos. Our model is calibrated on NEOWISE albedo data for the NEO population and reproduces these data very well once a simple model for the NEOWISE observational biases is applied. The results are consistent with previous estimates. There are about 1,000 NEOs with diameter D>1km and the mean albedo to convert absolute magnitude into diameter is 0.147. We do not find any statistically significant evidence that the albedo distribution of NEOs depends on NEO size. Instead, we find evidence that the disruption of NEOs at small perihelion distances found in Granvik et al. (2016) occurs preferentially for dark NEOs. The interval between km-sized bodies striking the Earth should occur on average once every 750,000 years. Low and high albedo NEOs are well mixed in orbital space, but a trend remains with higher albedo objects being at smaller semimajor axes and lower albedo objects more likely found at larger semimajor axes.

description: The HI Parkes All Sky Survey (HIPASS) is a blind extragalactic HI 21-cm emission line survey covering the whole southern sky from declination -90 to +25. The HIPASS catalogue (HICAT), containing 4315 HI-selected galaxies from the region south of declination +2, is presented in Meyer et al. (2004a, Paper I). This paper describes in detail the completeness and reliability of HICAT, which are calculated from the recovery rate of synthetic sources and follow-up observations, respectively. HICAT is found to be 99 per cent complete at a peak flux of 84 mJy and an integrated flux of 9.4 Jy km/s. The overall reliability is 95 per cent, but rises to 99 per cent for sources with peak fluxes >58 mJy or integrated flux > 8.2 Jy km/s. Expressions are derived for the uncertainties on the most important HICAT parameters: peak flux, integrated flux, velocity width, and recessional velocity. The errors on HICAT parameters are dominated by the noise in the HIPASS data, rather than by the parametrization procedure.

description: Megalencephalic leukoencephalopathy with subcortical cysts (MLC), or Van der Knaap disease, is a rare autosomal recessive disorder. It is characterized by macrocephaly that either presents at birth or develops during infancy. It occurs more commonly in some ethnicities where consanguinity is common, such as in the Turks, Agrawal community in India and Libyan Jews. Children can present with psychomotor development delay, with episodes of ataxia and spasticity.. The course of the disease is progressive with incomplete recovery following repeated episodic deteriorations. The project’s objective is to broadly summarize and report on the available evidence for the epidemiology, diagnosis and management of Van der Knaap disease

description: The eigensolutions of many-body quantum systems are always difficult to compute. The envelope theory is a method to easily obtain approximate, but reliable, solutions in the case of identical particles. It is extended here to treat systems with different particles (bosons or fermions). The accuracy is tested for several systems composed of identical particles plus a different one.

description: In the present paper we reconsider the integrable case of the Hamiltonian $N$-species Volterra system, as it has been introduced by Vito Volterra in 1937 and significantly enrich the results already published in the ArXiv in 2019 by two of the present authors (M. Scalia and O. Ragnisco). In fact, we present a new approach to the construction of conserved quantities and comment about the solutions of the equations of motion; we display mostly new analytical and numerical results, starting from the classical predator-prey model and arriving at the general $N$-species model

description: This Ph. D. thesis focuses on a study of hydrodynamics and oil/gas blowouts in deep water using the Regional Ocean Model System (ROMS) and GAS_DOCEAN models. The first objective was to analyze the potential impact of the Amazon and Pará Rivers on salinity, temperature and hydrodynamics in the Western Tropical North Atlantic between 60.5º-24ºW and 5ºS -16ºN. The ROMS was used to simulate the ocean hydrodynamics with 0.25º horizontal resolution and 32 vertical levels. In the ROMS model two experiments are carried out, one taking into account the discharge of freshwater from the rivers and the second, without releasing freshwater into the Atlantic ocean. The results of both simulations are compared determining the changes in temperature, salinity and surface currents produced by the influence of the rivers discharge. The Sea Surface Temperature difference between the simulations with river and no-river was about 2ºC. The Sea Surface Salinity difference was about 8 psu in the plume area confined to the littoral, with maximum from August to December and 4 psu in the area of the North Equatorial Countercurrent (NECC). The surface current velocities are stronger in the experiment with river and the strongest, close to the coast. The experiment with river causes a phase shift in the zonal currents anticipating the strongest velocities in the second semester of the year in 2 months, changing the seasonal cycle. The Mixed Layer Depth and Isothermal Layer Depth (ILD) in the experiment with river is 20 - 50 m shallower over the entire extension of the Amazon plume. The freshwater river discharge perform a fundamental role in the formation of Barrier Layer. The Oceanic Heat Content in the river experiments is smaller than the experiment without rivers, principally as a result of the shifts of the ILD. The second objective focuses on analyzing the behavior of oil/gas plumes from blowouts into deepwater. The simulations with the GAS_DOCEAN model were carried out in three points located at 50ºW, 5.25ºN, 44.5ºW, 0.5ºN and 42.75ºW, 1ºS . The time step was adjusted due to the particular oceanographic conditions at each point, in which, the initial velocity tends to zero and the coefficient 0.1 of the original equation was replaced by 0.0250 and 0.0375. All the plumes behaved as type 3. The seasonal current speed was small from the bottom to the surface, usually not exceeding 0.25 ms⁻¹; the maximum displacement of the plumes from its point of origin was not greater than 1 m. The mean plumes diameter on the surface varied between 54 and 79.7 m and the arrival time to the surface was from 7.25 to 8.05 hours.
