description: Osmotic Dehydration and Vacuum Impregnation are interesting operations in the food industry with applications in minimal fruit processing and/or freezing, allowing to develop new products with specific innovative characteristics.
Osmotic dehydration is widely used for the partial removal of water from cellular tissue by immersion in hypertonic (osmotic) solution. The driving force for the diffusion of water from the tissue is provided by the differences in water chemical potential between the external solution and the internal liquid phase of the cells. 
Vacuum Impregnation of porous products immersed in a liquid phase consist of reduction of pressure in a solid-liquid system (vacuum step) followed by the restoration of atmospheric pressure (atmospheric step). During the vacuum step the internal gas in the product pores is expanded and partially flows out while during the atmospheric step, there is a compression of residual gas and the external liquid flows into the pores (Fito, 1994). This process is also a very useful unit operation in food engineering as it allows to introduce specific solutes in the tissue which can play different functions (antioxidants, pH regulators, preservatives, cryoprotectants etc.).
The present study attempts to enhance our understanding and knowledge of fruit as living organism, interacting dynamically with the environment, and to explore metabolic, structural, physico-chemical changes during fruit processing. The use of innovative approaches and/or technologies such as SAFES (Systematic Approach to Food Engineering System), LF-NMR (Low Frequency Nuclear Magnetic Resonance), GASMAS (Gas in Scattering Media Absorption Spectroscopy) are very promising to deeply study these phenomena.
SAFES methodology was applied in order to study irreversibility of the structural changes of kiwifruit during short time of osmotic treatment. The results showed that the deformed tissue can recover its initial state 300 min after osmotic dehydration at 25 °C. 
The LF-NMR resulted very useful in water status and compartmentalization study, permitting to separate observation of three different water population presented in vacuole, cytoplasm plus extracellular space and cell wall.
GASMAS techniques was able to study the pressure equilibration after Vacuum Impregnation showing that after restoration of atmospheric pressure in the solid-liquid system, there was a reminding internal low pressure in the apple tissue that slowly increases until reaching the atmospheric pressure, in a time scale that depends on the vacuum applied during the vacuum step.
The physiological response of apple tissue on Vacuum Impregnation process was studied indicating the possibility of vesicular transport within the cells. Finally, the possibility to extend the freezing tolerance of strawberry fruits impregnated with cryoprotectants was proven.

description: Neighbourhood structures are the standard semantic tool used to reason about non-normal modal logics. The logic of all neighbourhood models is called classical modal logic. In coalgebraic terms, a neighbourhood frame is a coalgebra for the contravariant powerset functor composed with itself, denoted by 2^2. We use this coalgebraic modelling to derive notions of equivalence between neighbourhood structures. 2^2-bisimilarity and behavioural equivalence are well known coalgebraic concepts, and they are distinct, since 2^2 does not preserve weak pullbacks. We introduce a third, intermediate notion whose witnessing relations we call precocongruences (based on pushouts). We give back-and-forth style characterisations for 2^2-bisimulations and precocongruences, we show that on a single coalgebra, precocongruences capture behavioural equivalence, and that between neighbourhood structures, precocongruences are a better approximation of behavioural equivalence than 2^2-bisimulations. We also introduce a notion of modal saturation for neighbourhood models, and investigate its relationship with definability and image-finiteness. We prove a Hennessy-Milner theorem for modally saturated and for image-finite neighbourhood models. Our main results are an analogue of Van Benthem's characterisation theorem and a model-theoretic proof of Craig interpolation for classical modal logic.

description: Chondrites stem from undifferentiated asteroidal parent bodies that nevertheless experienced a certain degree of metamorphism after their formation in the early solar system. Maximum temperatures of metamorphism depend mainly on formation time and the abundance of the main heating source, which is short-lived 26Al. Enstatite chondrites formed under reducing conditions and include many strongly metamorphosed members of petrologic type 6. We model the thermal evolution of the parent body of the low metal enstatite chondrite class (EL). The model takes into account accretion, heating, sintering and compaction by hot pressing of the initially porous material, temperature dependent heat conductivity, and insulation effects by the remaining regolith layer. Key parameters of the parent body (formation time, radius, and porosity) are estimated by fitting thermal histories of EL6 chondrites (LON 94100, Neuschwanstein, Khairpur, Blithfield, Daniel's Kuil), constrained mainly by I-Xe and Ar-Ar ages and their respective closure temperatures. Viable fits are obtained for parent bodies with 120 -- 210 km radius, formed c. 1.8 -- 2.1 Ma after Ca,Al-rich inclusions (CAIs), and an initial porosity of 30%, relatively independent on initial disk temperatures. Thermal histories of the different EL6 chondrites are indistinguishable and so are their burial depths. While the exact layering depth is somewhat model dependent (c. 12--20 km), the thickness of the layer from which all five EL6 chondrites stem is < 1 km. Hence, an origin from a quite small asteroidal fragment is possible, particular as most excavation ages inferred from cosmic ray exposure data are compatible with a separation as meter sized meteoroids from a small Apollo asteroid 33 Ma ago.

Subjects: M-PSI/08 Psicologia clinica

description: Introduction: The term Clinimetric was introduced by Feinstein in 1982, who first noticed that despite all the improvements in the assessment methods, a number of clinical phenomena were still unconsidered during the evaluation process. Yet today clinical phenomena, such as stress, relevant in diseases progression and course, are not completely evaluated. Only recently, according to the clinimetric approach, Fava and colleagues have introduced specific criteria for evaluating the allostatic overload in clinical setting. 
Methods: Participants were 240 blood donors recruited from May 2007 to December 2009 in 4 different blood Centers (AVIS) in Italy. Blood samples from each participant were collected for laboratory test the same day the self-rating instruments were administered (Psychosocial Index, Symptom Questionnaire, Psychological well-being scales, Temperament and Character inventory, Self-Report Altruism scale). The study explore different aspects describing sample characteristics and correlates of stress in the total sample (part I), new selection criteria applied to existing instruments to identify individuals reporting allostatic load (part II), and differences on biological correlates between subjects with vs without AL.
Results: Significant differences according to gender and past illnesses have been found in different dimensions of well-being and distress. Further, distress was explained for more than 60% by 4 main factors such as anxiety, somatic symptoms, environmental mastery and persistence. According to the new criteria, 98 donors reported AL. Allostatic load individuals reported to engage in less altruistic behaviours. Also they differ in personality traits and characters from controls. In the last part, results showed significant differences among donors according to allostatic load on diverse biological parameters (RBC, MCV, immune essay).
Conclusion: This study presents obvious limitations due to its preliminary nature. Further research are need to confirm that these new criteria may lead to identify high risk individuals reporting not only stressful situations but also vulnerabilities.

description: The laser driven ion acceleration is a burgeoning field of resarch
and  is attracting a growing number of scientists since the first results reported in 2000 obtained
irradiating thin solid foils by high power laser pulses.
The growing interest is driven by the peculiar characteristics of the produced bunches,
the compactness of the whole accelerating system and the very short
accelerating length of this all-optical accelerators.

A fervent theoretical and experimental work has been done since then.
An important part of the theoretical study is done by means of numerical simulations and the most widely used
technique exploits PIC codes (“Particle In Cell'”).
In this thesis the PIC code AlaDyn, developed by our research group considering innovative
algorithms, is described. My work
has been devoted to the developement of the code and
the investigation of the laser driven ion acceleration
for different target configurations.
Two target configurations for the proton acceleration are
presented together with the results of the 2D and 3D numerical investigation.
One target configuration consists of a solid foil  with a low density layer attached on the
irradiated side. The nearly critical plasma of the foam layer allows a very
high energy absorption by the target and an increase of the proton
energy up to a factor 3, when compared to the ``pure'' TNSA configuration.
The differences of the regime with respect to the  standard TNSA are described
The case of nearly critical density targets has been investigated with
3D simulations. In this case the laser travels throughout the plasma
and exits on the rear side. During the propagation, the laser drills a channel
and induce a magnetic vortex that expanding on the rear side of the targer is source of a
very intense electric field. The protons of the plasma are
strongly accelerated up to energies of 100 MeV using a 200PW laser.

A delicate measurement of this difference at a super flavor factory (e.g., the ϕfactory) will provide us with a robust test of CPT symmetry in the neutral kaon system.

Statistical analysis and simulation techniques in wall-bounded turbulence
Creators: name: Cimarelli, Andrea <1983>
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2011
Subjects: ING-IND/06 Fluidodinamica

description: The present work is devoted to the assessment of the energy fluxes physics in the space of scales and
physical space of wall-turbulent flows. The generalized Kolmogorov equation will be applied to
DNS data of a turbulent channel flow in order to describe the energy fluxes
paths from production to dissipation in the augmented space of wall-turbulent flows.
This multidimensional description will be shown to be crucial
to understand the formation and sustainment of the turbulent fluctuations fed by the energy fluxes
coming from the near-wall production region.
An unexpected behavior of the energy fluxes comes out from
this analysis consisting of spiral-like paths in the combined physical/scale space where the controversial
reverse energy cascade plays a central role. The observed behavior conflicts with the classical notion of the
Richardson/Kolmogorov energy cascade and may have strong repercussions on both theoretical and modeling
approaches to wall-turbulence. To this aim a new relation stating the leading physical processes governing
the energy transfer in wall-turbulence is suggested and shown able to capture most of the rich dynamics of
the shear dominated region of the flow. Two dynamical processes are identified as driving mechanisms
for the fluxes, one in the near wall region and a second one further away from the wall. The former,
stronger one is related to the dynamics involved in the near-wall turbulence regeneration cycle. The second
suggests an outer self-sustaining mechanism which is asymptotically expected to take place in the log-layer and
could explain the debated mixed inner/outer scaling of the near-wall statistics.

The same approach is applied for the first time to a filtered velocity field. A generalized Kolmogorov
equation specialized for filtered velocity field is derived and discussed.
The results will show what effects the subgrid scales have on the resolved motion in both physical
and scale space, singling out the prominent role of the filter length compared to the cross-over scale
between production dominated scales and inertial range, lc, and the reverse energy cascade region lb. The systematic characterization of the resolved and subgrid physics as function of the filter
scale and of the wall-distance will be shown instrumental for a correct use of LES models in the
simulation of wall turbulent flows. Taking inspiration from the new relation for the energy transfer in
wall turbulence, a new class of LES models will be also proposed. Finally, the generalized Kolmogorov equation
specialized for filtered velocity fields will be shown
to be an helpful statistical tool for the assessment of LES models and for the development of new ones.
As example, some classical purely dissipative eddy viscosity models are analyzed via an a priori procedure.

description: Abstract

Patient safety remains a critical concern in healthcare, particularly in developing countries, where millions of adverse events are reported annually. Globally, patient safety incidents are on the rise, with significant disparities in reporting and outcomes across regions, underscoring the urgent need for improved safety protocols, robust reporting systems, to enhance healthcare quality and reduce harm. This study aims to explore the determinants of patient safety culture—specifically structural empowerment, professionalism, and emotional exhaustion—and their influence on patient safety outcomes and incident reporting. Employing a cross-sectional method, quantitative data were collected from digital questionnaires given to 161 health workers. The data was analyzed using the SmartPLS 4.0.9.6. The findings reveal that both structural empowerment and professionalism have a significant positive impact on patient safety culture. However, emotional exhaustion does not substantially affect either incident reporting or patient safety outcomes. Notably, there is evidence that the emphasis on safeguarding patients has a significant mediating effect on structural empowerment and professionalism. These insights contribute to the understanding of how specific factors influence patient safety culture and highlight the need for targeted interventions to enhance safety practices in healthcare settings.
Japan’s postwar experience with technology transfer
Creators: name: Goode, James Thomas
Publisher: name: University of British Columbia
Year: 2010

description: The international transfer of technology is increasingly seen as a major element in economic development for both the developed and less-developed countries. The thesis examines Japan's postwar economic development and the role played in that process by imported, foreign technologies. The discussion focuses on commercial transfers of technology and, because of the frequent close connection between technology transfer and foreign direct investment, there is considerable discussion of foreign direct investment in Japan. The paper is based on an extensive review of existing government and nongovernment material in both Japanese and English and on a series of interviews with Japanese government and business officials involved in postwar transfers. In addition, three case studies of technology transfers were carried out and are included as appendices. Fallowing an introductory chapter dealing with general issues of technology transfer and economic development, the postwar Japanese experience is treated chronologically for the period: 1945-1955 "Japan's Postwar Recovery", 1955-1963 "Structural Transformation", and 1963-1973 "Liberalization and Internationalization". The central importance to Japan's postwar development of the period of "structural transformation", and the technology transfer which took place during that period, is stressed. The current status of technology transfer in Japan is also discussed and the present and future importance to Japan of technology exportation and independent technology development is pointed out. A concluding chapter outlines major special characteristics of the Japanese postwar experience and suggest what lessons it may hold for others. It is argued that the favourable domestic and benign international environments as well as the large size of the domestic market and a basic antipathy to foreign direct investment are all special characteristics which strongly influenced the course of postwar technology transfer to Japan. On the other hand, a competitive domestic business environment, consultation between government planners and businessmen, selective or discriminatory development policy, and widespread public support for goals supportive of technology change are all argued to be aspects of the postwar Japanese experience which hold important and general lessons for other countries.

In the rotating reference frame, by a finite dimensional reduction, we prove the existence of non radial stationary solutions whose supports are made of an arbitrarily large number of disjoint compact sets, in the low angular velocity and large scale limit. At first order, the solutions behave like point particles, thus making the link with the relative equilibria} in N-body dynamics.

description: The origins of the diffuse flux of cosmogenic PeV neutrinos detected in the IceCube experiment during 2010 - 2017 remain unidentified. A population of extragalactic newly born fast spinning pulsars are investigated as possible candidates for generating the PeV energy scale neutrinos. A two-step mechanism of particle acceleration is adopted for transferring energy from star rotation to high energy electrons. Electrons might be boosted up to $\approx 0.01$ EeV energies and above, and produce ultra-high-energy (UHE) neutrinos and gamma rays when these electrons interact with low energy positrons and soft radiations in the acceleration zone. The theoretically derived extragalactic diffuse muon neutrino flux in the energy range [1-10] PeV is found consistent with the IceCube level if only a fraction ($η_{k} \approx 0.31\%$) of the total bolometric luminosity of pulsars are transferred to power the PeV neutrinos. Using the above value of the cosmic ray electron loading parameter $η_{k}$, the diffuse gamma ray flux from inverse Compton scattering off UHE electrons in the soft radiation field might be predicted from the model.

description: Recent experiments exhibit a rate-dependence for granular shear such that the stress grows linearly in the logarithm of the shear rate, \dotγ. Assuming a generalized activated process mechanism, we show that these observations are consistent with a recent proposal for a stress-based statistical ensemble. By contrast, predictions for rate-dependence using conventional energy-based statistical mechanics to describe activated processes, predicts a rate dependence that of (\ln (\dotγ))^{1/2}.

description: We study the direction-dependent drag acting on a cylindrical solid intruder with length $L$ and diameter $D$ as it moves in water-saturated granular beds at constant depth. Polysterene and hydrogel grains with diameter $d$ are used to investigate materials which have high contact friction and those which are nearly frictionless, respectively. The drag on the intruder is measured while oriented perpendicular $F_\perp$ and parallel $F_\parallel$ to its axis as a function of speed $U$ from the quasi-static to the rate-dependent regime. We find that the drag anisotropy $ξ= F_\perp/F_\parallel$ is not constant, and increases significantly with driving rate and $L/D$ in both mediums. In particular for $L/D = 40$, $ξ$ increases from 2.6 to 4.5, and from 7.0 to 8.2 in the high and low friction beds, respectively, as the nondimensional Froude number $Fr =U/\sqrt{g(D+d)}$ is varied between $10^{-4}$ and $2 \times 10^{-2}$. On average, $ξ$ is observed to increase logarithmically with $L/D$ for $L/D \gg 1$. Exploiting the index-matched nature of hydrogel grains in water, we further show that the sediment flow around the cylinder in the two orientations is consistent with skin friction dominated drag. The relative contributions of the cylindrical side and the circular flat-ends on $ξ$ are estimated with thin disks to understand the observed variation of drag with aspect ratio and surface friction.

description: We study slow dynamics of particles moving in a matrix of immobile obstacles using molecular dynamics simulations. The glass transition point decreases drastically as the obstacle density increases. At higher obstacle densities, the dynamics of mobile particles changes qualitatively from glass-like to a Lorentz-gas-like relaxation. This crossover is studied by density correlation functions, nonergodic parameters, mean square displacement, and nonlinear dynamic susceptibility. Our finding is qualitatively consistent with the results of recent numerical and theoretical studies on various spatially heterogeneous systems. Furthermore, we show that slow dynamics is surprisingly rich and sensitive to obstacle configurations. Especially, the reentrant transition is observed for a particular configuration, although its origin is not directly linked to the similar prediction based on mode-coupling theory.

description: We propose a nonlocal theory of single-particle excitations. It is based on an off-diagonal effective medium and the projection operator method for treating the retarded Green function. The theory determines the nonlocal effective medium matrix elements by requiring that they are consistent with those of the self-energy of the Green function. This arrows for a description of long-range intersite correlations with high resolution in momentum space. Numerical study for the half-filled Hubbard model on the simple cubic lattice demonstrates that the theory is applicable to the strong correlation regime as well as the intermediate regime of Coulomb interaction strength. Furthermore the results show that nonlocal excitations cause sub-bands in the strong Coulomb interaction regime due to strong antiferromagnetic correlations, decrease the quasi-particle peak on the Fermi level with increasing Coulomb interaction, and shift the critical Coulomb interaction Uc2 for the divergence of effective mass towards higher energies at least by a factor of two as compared with that in the single-site approximation.

description: Abstract

Background: Anxiety disorders among school-going adolescents in Villupuram district of Tamil Nadu have emerged as a pressing concern, mirroring broader patterns across India. This study aims to estimate the prevalence and identify factors associated with anxiety disorders in this demographic, providing insights for targeted interventions and comprehensive strategies to address adolescent mental health. Methods: A cross-sectional study design was employed, sampling school-going adolescents aged 10 to 17 years from private schools in Villupuram District, Tamil Nadu. A structured questionnaire and the Screen for Child Anxiety Related Disorders (SCARED) scale were utilized for data collection, with the analysis performed using descriptive and inferential statistics in SPSS version 22. Results: The study involved 361 participants, highlighting a high prevalence of anxiety disorders at 75.05%, with a higher incidence among girls (81.3%) compared to boys (69.0%). Sociodemographic factors such as gender, absence of leisure time, and academic pressure showed significant associations with the occurrence of anxiety disorders. Female adolescents, in particular, exhibited a two-fold increase in the prevalence of anxiety disorders compared to males. Conclusion: The study's findings affirm the significant prevalence of anxiety disorders among school-going adolescents in Villupuram district, with notable gender disparities and correlations with academic pressures and lifestyle factors. These insights emphasize the need for a multidisciplinary approach involving gender-sensitive interventions, educational reforms, and integrated mental health services, urging stakeholders to collaborate in creating a supportive environment for the mental well-being of adolescents in India.

description: We develop a mixture model and diagnostic for Bayesian estimation and selection in high-order, discrete-state Markov chains. Both extend the mixture transition distribution, which constructs a transition probability tensor by aggregating probabilities from a set of single-lag transition matrices, through inclusion of mixture components dependent on multiple lags. We demonstrate two uses for the proposed model: identification of relevant lags through over-specification and shrinkage via priors for sparse probability vectors, and parsimonious approximation of multi-lag dynamics by mixing low-order transition models. The diagnostic yields a general and interpretable mixture decomposition for transition probability tensors estimated by any means. We demonstrate the utility of the model and diagnostic with simulation studies, and further apply the methodology to a data analysis from the high-order Markov chain literature, and to a time series of pink salmon abundance in Alaska, U.S.A.

description: Alternative materials are required to enhance the efficacy of plasmonic devices. We discuss the optical properties of a number of alloys, doped metals, intermetallics, silicides, metallic glasses and high pressure materials. We conclude that due to the probability of low frequency interband transitions, materials with partially occupied d-states perform poorly as plasmonic materials, ruling out many alloys, intermetallics and silicides as viable. The increased probability of electron-electron and electron-phonon scattering rules out many doped and glassy metals.

Systems of nonlinear PDEs arising from multi-dimensional and multi-fluid viscous shear flows
Creators: name: Alexander, John
Publisher: name: Imperial College London

description: In this thesis, mathematical systems of coupled differential equations arising in fluid dynamics are studied; motivated by the insight they provide in understanding and prompting experimental results as well as the opportunity they present to develop tools to investigate their rich dynamical system. To cover a wide range of physical arrangements and parabolic PDEs, three problems are posed; connected via the types of equations which govern their motion and the techniques used to study them. The multiplicity of the equations is first generated by the interaction between a fluid and a flexible substrate, where the evolution of the fluid's free-boundaries are coupled through the fluid. The resonant interaction is shown to cause linear instabilities at a range of Reynolds numbers, from the Stokes flow limit to very high values where a Chebyshev-Tau numerical approach was required; providing a foundation for future nonlinear studies. Similarly, the evolution of the two free-boundaries in a three-layer channel flow, applicable in microfluidics, form a system of PDEs, where novel, asymmetric instabilities were found in the inertialess regime. Numerical simulations demonstrated complex, nonlinear behaviour; supporting the transition of the parabolic PDEs' advection component from hyperbolic to elliptic. Modern modelling techniques of falling films (namely WIBL) consist of multiple evolution equations for the properties of the fluid, and are applied here to study the stability and dynamics of rivulets supporting travelling lenses, as observed in previous experiments. A quasi-static linear stability analysis about the rivulets provides the growth rate, spacing and small-amplitude surface profiles of the subsequent linear instability. Further numerical simulations extended these into the nonlinear regime where three-dimensional travelling waves, qualitatively comparable to snapshots of those seen in experiment, were found for the Benney equation and similar form, large-time dewetting waves and time-periodicity for the higher-order models. Supplementary code is provided in accompanying repositories.

description: We create a complete gravity torque map of the disk of the LINER/Seyfert 1.9 galaxy NGC4579. We quantify the efficiency of angular momentum transport and search for signatures of secular evolution in the fueling process from r~15kpc down to the inner r~50pc around the Active Galactic Nucleus (AGN). We use both the 1-0 and 2-1 line maps of CO obtained with the Plateau de Bure Interferometer (PdBI) as part of the NUclei of Galaxies-(NUGA)-project. We derive the stellar potential from a NIR (K band) wide field image of the galaxy. The K-band image, which reveals a stellar bar, together with a high resolution HI map of NGC4579 obtained with the Very Large Array (VLA), allow us to extend the gravity torque analysis to the outer disk. The bulk of the gas response traced by the CO PdBI maps follows the expected gas flow pattern induced by the bar potential in the presence of two Inner Lindblad Resonances (ILR). We also detect an oval distortion in the inner r~200pc of the K-band image. The oval is not aligned with the large-scale bar, a signature of dynamical decoupling. The morphology of the outer disk suggests that the neutral gas is currently piling up in a pseudo-ring formed by two winding spiral arms that are morphologically decoupled from the bar structure. In the outer disk, the decoupling of the spiral allows the gas to efficiently produce net gas inflow on intermediate scales. The corotation barrier seems to be overcome due to secular evolution processes. The gas in the inner disk is efficiently funneled by gravity torques down to r~300pc. Closer to the AGN, the two m=2 modes (bar and oval) act in concert to produce net gas inflow down to r~50pc, providing a clear smoking gun evidence of fueling with associated short dynamical time-scales.

Adaptive multiscale biological signal processing

description: Biological processes are very complex mechanisms, most
of them being accompanied by or manifested as signals
that reflect their essential characteristics and qualities. The
development of diagnostic techniques based on signal and
image acquisition from the human body is commonly retained
as one of the propelling factors in the advancements
in medicine and biosciences recorded in the recent past.
It is a fact that the instruments used for biological signal
and image recording, like any other acquisition system,
are affected by non-idealities which, by different degrees,
negatively impact on the accuracy of the recording. This
work discusses how it is possible to attenuate, and ideally
to remove, these effects, with a particular attention toward
ultrasound imaging and extracellular recordings.
Original algorithms developed during the Ph.D. research
activity will be examined and compared to ones in literature
tackling the same problems; results will be drawn on the
base of comparative tests on both synthetic and in-vivo
acquisitions, evaluating standard metrics in the respective
field of application. All the developed algorithms share an
adaptive approach to signal analysis, meaning that their
behavior is not dependent only on designer choices, but
driven by input signal characteristics too.
Performance comparisons following the state of the art
concerning image quality assessment, contrast gain estimation
and resolution gain quantification as well as visual
inspection highlighted very good results featured by the
proposed ultrasound image deconvolution and restoring
algorithms: axial resolution up to 5 times better than algorithms
in literature are possible. Concerning extracellular
recordings, the results of the proposed denoising technique
compared to other signal processing algorithms pointed
out an improvement of the state of the art of almost 4 dB.

description: While the entire field of privacy preserving data analytics is focused on the privacy-utility tradeoff, recent work has shown that privacy preserving data publishing can introduce different levels of utility across different population groups. It is important to understand this new tradeoff between privacy and equity as privacy technology is being deployed in situations where the data products will be used for research and policy making. Will marginal populations see disproportionately less utility from privacy technology? If there is an inequity how can we address it?

description: Abstract

The study of social networks has received a lot of attention lately. One way to represent social networks is via a graph. Every person is referred to as a node and the links that connect them as edges when analyzing social networks. In real-world network graphs, it is challenging to identify communities and describe the relationships between items and persons. There are several well-established techniques for finding the connected nodes that lead to the identification of communities. This research integrates the k-nearest neighbours (KNN) algorithm with unnormalized spectral clustering to provide a unique approach for community recognition in social networks. The method makes use of KNN for local neighbourhood refining and spectral clustering for global structure analysis. The primary objective of the algorithm proposed in this study is to identify and eliminate any noisy nodes from the identified communities, hence enhancing the quality of the identified communities.  Experimental results on real-world datasets demonstrate the method's effectiveness in accurately identifying community structures.

description: The Abell 780 cluster, better known as the Hydra A cluster, has been thouroughly analyzed in X-rays. However, little is known on its optical properties. We derive the galaxy luminosity function (GLF) in this apparently relaxed cluster, and search for possible environmental effects by comparing the GLFs in various regions, and by looking at the galaxy distribution at large scale around Abell 780. Our study is based on optical images obtained with the ESO 2.2m telescope and WFI camera in the B and R bands, covering a total region of 67.22x32.94 arcmin^2, or 4.235x2.075 Mpc^2 for a cluster redshift of 0.0539. In a region of 500 kpc radius around the cluster centre, the GLF in the R band shows a double structure, with a broad and flat bright part and a flat faint end that can be fit by a power law with an index alpha=-0.85+-0.12 in the 20.25
