description: We present an X-ray-optical cross-correlator for the soft (> 150 eV) up to the hard X-ray regime based on a molybdenum-silicon superlattice. The cross-correlation is done by probing intensity and position changes of superlattice Bragg peaks caused by photoexcitation of coherent phonons. This approach is applicable for a wide range of X-ray photon energies as well as for a broad range of excitation wavelengths and requires no external fields or changes of temperature. Moreover, the cross-correlator can be employed on a 10 ps or 100 fs time scale featuring up to 50% total X-ray reflectivity and transient signal changes of more than 20%. (C) 2016 Author(s).

Hybrid Finite-Discrete Element Modeling of the Mode I Tensile Response of an Alumina Ceramic

Publisher: name: University of Alberta Library
Year: 2023

We have developed a three-dimensional hybrid finite-discrete element model to investigate the mode I tensile opening failure of alumina ceramic. This model implicitly considers the flaw system in the material and explicitly shows the macroscopic failure patterns. A single main crack perpendicular to the loading direction is observed during the tensile loading simulation. Some fragments appear near the crack surfaces due to crack branching. The tensile strength obtained by our model is consistent with the experimental results from the literature. Once validated with the literature, the influences of the distribution of the flaw system on the tensile strength and elastic modulus are explored. The simulation results show that the material with more uniform flaw sizes and fewer big flaws has stronger tensile strength and higher elastic modulus.

description: Naturalness in supersymmetry (SUSY) is under siege by increasingly stringent LHC constraints, but natural electroweak symmetry breaking still remains the most powerful motivation for superpartner masses within experimental reach. If naturalness is the wrong criterion then what determines the mass scale of the superpartners? We motivate supersymmetry by (1) gauge coupling unification, (2) dark matter, and (3) precision b-tau Yukawa unification. We show that for an LSP that is a bino-Higgsino admixture, these three requirements lead to an upper-bound on the stop and sbottom masses in the several TeV regime because the threshold correction to the bottom mass at the superpartner scale is required to have a particular size. For tan beta about 50, which is needed for t-b-tau unification, the stops must be lighter than 2.8 TeV when A_t has the opposite sign of the gluino mass, as is favored by renormalization group scaling. For lower values of tan beta, the top and bottom squarks must be even lighter. Yukawa unification plus dark matter implies that superpartners are likely in reach of the LHC, after the upgrade to 14 (or 13) TeV, independent of any considerations of naturalness. We present a model-independent, bottom-up analysis of the SUSY parameter space that is simultaneously consistent with Yukawa unification and the hint for m_h = 125 GeV. We study the flavor and dark matter phenomenology that accompanies this Yukawa unification. A large portion of the parameter space predicts that the branching fraction for B_s to mu^+ mu^- will be observed to be significantly lower than the SM value.

description: Human participants play a central role in the development of modern artificial intelligence (AI) technology, in psychological science, and in user research. Recent advances in generative AI have attracted growing interest to the possibility of replacing human participants in these domains with AI surrogates. We survey several such "substitution proposals" to better understand the arguments for and against substituting human participants with modern generative AI. Our scoping review indicates that the recent wave of these proposals is motivated by goals such as reducing the costs of research and development work and increasing the diversity of collected data. However, these proposals ignore and ultimately conflict with foundational values of work with human participants: representation, inclusion, and understanding. This paper critically examines the principles and goals underlying human participation to help chart out paths for future work that truly centers and empowers participants.

description: Thanks to works by M. Kontsevich and A. Zorich followed by C. Boissy, we have a classification of all Rauzy Classes of any given genus. It follows from these works that Rauzy Classes are closed under the operation of inverting the permutation. In this paper, we shall prove the existence of self-inverse permutations in every Rauzy Class by giving an explicit construction of such an element satisfying the sufficient conditions. We will also show that self-inverse permutations are Lagrangian, meaning any suspension has its vertical cycles span a Lagrangian subspace in homology. This will simplify the proof of a lemma in a work by G. Forni. W. A. Veech proved a bound on the number of distinct ergodic probability measures for a given minimal interval exchange transformation. We verify that this bound is sharp by construcing examples in each Rauzy Class.

description: In de zeventiger jaren van onze eeuw is de belangstelling voor de Middeleeuwse archeologie nogal toegenomen, met als gevolg dat de middeleeuwsc keramiek meer aandacht kreeg dan voorheen.

Sedert 1979 werden in her Roeselaarse verschillende duizenden potscherven ingezameld uit de vroege en late middeleeuwen. Dit gebeurde door veldprospecties en nazicht van allerlei soorten grondwerken: opspuitingen, doleringswerken, baggerwerken, draineringswerken, aanleg van buizen

voor gas en waterleiding, dit vooral aan de rand van de stad. Daarbij onderzochten wij ook restanten van oude gebouwen, meer in de stadskern gelegen. In de meeste gevallen werd hier nog gered wat overbleef van meestal erg verstoorde vindplaatsen. Datering van deze archeologica, aan de hand van stratigrafische gegevens, is dan, op één uitzondering na, meestal uitgesloten. Dit betekent echter niet dat we geen oog zouden hebben voor de stratigrafische gegevens: het vastleggen van de profielen, of het situeren van voorwerpen

en sporen in bodem en randen van de gegraven sleuf. Uitgaande van het feit dat van meerdere bodemlagen de bovenste jonger is dan de onderste (stratigrafie) wordt door systematischc opgravingen de diepte van de tijd gepeild.

Bij ons gaat het dus duidelijk nog niet, om systematische opgravingen. Wij willen enkel aantonen wat aan het daglicht kwam door veldprospecties en door allerlei waarnemingen bij grondwerken. De getekende en beschreven aardewerkfragmenten dienen dus aanzien te worden als oppervlaktevondsten.

description: This article introduces a passive four-degree-of-freedom foot interface to control a robotic surgical instrument. This interface is based on a parallel-serial hybrid mechanism with springs and force sensors. In contrast to existing switch-based interfaces that can command a slave robot arm at constant speed in only discrete directions, the novel interface provides an operator with intuitive control in continuous directions and speed with force and position feedback. The output command of the interface was initially derived based on the kinematics and statics of the interface. Since distinct movement patterns among different subjects were observed in a pilot test, a data-driven approach using independent component analysis was developed to convert the foot inputs to the control commands of the user. The capability of this interface in controlling a robotic arm in multiple degrees of freedom was further verified with a teleoperation test.

description: We study Higgs production and decays in the context of natural SUSY, allowing for an extended Higgs sector to account for a 125 GeV lightest Higgs boson. Under broad assumptions, Higgs observables at the LHC depend on at most four free parameters with restricted numerical ranges. Two parameters suffice to describe MSSM particle loops. The MSSM loop contribution to the diphoton rate is constrained from above by direct stop and chargino searches and by electroweak precision tests. Naturalness, in particular in demanding that rare B decays remain consistent with experiment without fine-tuned cancellations, provides a lower (upper) bound to the stop contribution to the Higgs-gluon coupling (Higgs mass). Two parameters suffice to describe Higgs mixing, even in the presence of loop induced non-holomorphic Yukawa couplings. Generic classes of MSSM extensions, that address the fine-tuning problem, predict sizable modifications to the effective bottom Yukawa, yb. Non-decoupling gauge extensions enhance yb, while a heavy SM singlet reduces yb. A factor of 4-6 enhancement in the diphoton rate at the LHC, compared to the SM prediction, can be accommodated. The ratio of the enhancements in the diphoton vs. the WW and ZZ channels cannot exceed 1.4. The h to bbbar rate in associated production cannot exceed the SM rate by more than 50%.

description: This study explores how discussing metaphors for AI can help build awareness of the frames that shape our understanding of AI systems, particularly large language models (LLMs) like ChatGPT. Given the pressing need to teach "critical AI literacy", discussion of metaphor provides an opportunity for inquiry and dialogue with space for nuance, playfulness, and critique. Using a collaborative autoethnographic methodology, we analyzed metaphors from a range of sources, and reflected on them individually according to seven questions, then met and discussed our interpretations. We then analyzed how our reflections contributed to the three kinds of literacies delineated in Selber's multiliteracies framework: functional, critical, and rhetorical. These allowed us to analyze questions of ethics, equity, and accessibility in relation to AI. We explored each metaphor along the dimension of whether or not it was promoting anthropomorphizing, and to what extent such metaphors imply that AI is sentient. Our findings highlight the role of metaphor reflection in fostering a nuanced understanding of AI, suggesting that our collaborative autoethnographic approach as well as the heuristic model of plotting AI metaphors on dimensions of anthropomorphism and multiliteracies, might be useful for educators and researchers in the pursuit of advancing critical AI literacy.

What We Can Learn About Planets From Imaging Debris Disks
Creators: name: Wyatt, Mark
Publisher: name: Zenodo
Year: 2016

description: The debris disk phase starts once the protoplanetary disk has dispersed and there is no longer sufficient gas to influence the dust, though secondary gas may still be present. At this stage the structure of the debris disk is set by where planetesimals were able to form and how they have been influenced by perturbations from any planets, as well as the physics of the dust production mechanism. Thus observations of debris disks provide valuable information on the outcome of the planetesimal and planet formation processes that took place in the protoplanetary disk, as well as about the architecture and evolution of the planetary system. This talk will review these processes and how high resolution observations of debris disks have contributed to our understanding of their underlying planetary systems and their formation mechanism.

description: Supported lipid membranes are useful and important model systems for studying cell membrane properties and membrane mediated processes. One attractive application of supported membranes is the design of phantom cells exhibiting well defined adhesive properties and receptor densities. Adhesion of membranes may be achieved by specific and non-specific interactions, and typically requires the clustering of many adhesion bonds into "adhesion domains". One potential mediator of the early stages of the aggregation process is the Casimir-type forces between adhesion sites induced by the membrane thermal fluctuations. In this review, I will present a theoretical analysis of fluctuation induced aggregation of adhesion sites in supported membranes. I will first discuss the influence of a single attachment point on the spectrum of membrane thermal fluctuations, from which the free energy cost of the attachment point will be deduced. I will then analyze the problem of a supported membrane with two adhesion points. Using scaling arguments and Monte Carlo simulations, I will demonstrate that two adhesion points attract each other via an infinitely long range effective potential that grows logarithmically with the pair distance. Finally, I will discuss the many-body nature of the fluctuation induced interactions. I will show that while these interactions alone are not sufficient to allow the formation of aggregation clusters, they greatly reduce the strength of the residual interactions required to facilitate cluster formation. Specifically, for adhesion molecules interacting via a short range attractive potential, the strength of the direct interactions required for aggregation is reduced by about a factor of two to below the thermal energy $k_BT$.

description: Background: Staphylococcus aureus is an aerobic, Gram positive commensal organism that is capable of causing a wide spectrum of disease. This study contributes to previously published literature regarding daptomycin versus vancomycin use in S. aureus bacteremia (SAB).  Methods: Adult patients admitted between 2010 and 2014, billed for ICD-9 code V09.0, 038.11, 038.12, 041.11, or 041.12, and received vancomycin and daptomycin were included in this retrospective analysis. Patients were stratified by time to change in antibiotics from vancomycin to daptomycin to the early switch (1-3 days), intermediate switch (4-7 days), or late switch (8 days or later) group. The primary outcome was treatment failure defined as 30-day recurrence, 60-day all-cause mortality, and 90-day all-cause readmission.  Results: 193 patients were enrolled in the final cohort. The overall treatment failure rate was 18% with no differences between early switch, intermediate switch, and late switch (P=0.72) groups. Independent predictors of treatment success were length of stay (OR=1.035) and time to positive culture (OR=0.961).  Conclusions: Results of this study did not demonstrate a difference in treatment failure based on time to switch from vancomycin to daptomycin. Future research should focus on optimizing use of vancomycin and daptomycin and medical management of SAB.

description: We analyze the possibility that due to their superfluid properties some compact astrophysical objects may contain a significant part of their matter in the form of a Bose-Einstein condensate. To study the condensate we use the Gross-Pitaevskii equation, with arbitrary non-linearity. By introducing the Madelung representation of the wave function, we formulate the dynamics of the system in terms of the continuity equation and of the hydrodynamic Euler equations. The non-relativistic and Newtonian Bose-Einstein gravitational condensate can be described as a gas, whose density and pressure are related by a barotropic equation of state. In the case of a condensate with quartic non-linearity, the equation of state is polytropic with index one. In the framework of the Thomas-Fermi approximation the structure of the Newtonian gravitational condensate is described by the Lane-Emden equation, which can be exactly solved. The case of the rotating condensate is also discussed. General relativistic configurations with quartic non-linearity are studied numerically with both non-relativistic and relativistic equations of state, and the maximum mass of the stable configuration is determined. Condensates with particle masses of the order of two neutron masses (Cooper pair) and scattering length of the order of 10-20 fm have maximum masses of the order of 2 M_sun, maximum central density of the order of 0.1-0.3 10^16 g/cm^3 and minimum radii in the range of 10-20 km. In this way we obtain a large class of stable astrophysical objects, whose basic astrophysical parameters (mass and radius) sensitively depend on the mass of the condensed particle, and on the scattering length. We also propose that the recently observed neutron stars with masses in the range of 2-2.4 M_sun are Bose-Einstein Condensate stars.

description: We use Hubble Space Telescope imaging to show that the nearby dwarf starburst galaxy NGC 4449 has an unusual abundance of luminous red star clusters. Joint constraints from integrated photometry, low-resolution spectroscopy, dynamical mass-to-light ratios, and resolved color-magnitude diagrams provide evidence that some of these clusters are old globular clusters. Spectroscopic data for two massive clusters suggest intermediate metallicities ([Fe/H] ~ -1) and subsolar Mg enhancement ([Mg/Fe] ~ -0.1 to -0.2). One of these clusters may be the nucleus of a tidally disrupting dwarf galaxy; the other is very massive (~ 3 x 10^6 M_sun). We have also identified a population of remote halo globular clusters. NGC 4449 is consistent with an emerging picture of the ubiquity of stellar halos among dwarf galaxies, and study of its globular clusters may help distinguish between accretion and in situ scenarios for such halos.

description: We investigate the nature of the inner accretion disk in the neutron star source GX 5-1 by making a detailed study of time lags between X-rays of different energies. Using the cross-correlation analysis, we found anti-correlated hard and soft time lags of the order of a few tens to a few hundred seconds and the corresponding intensity states were mostly the horizontal branch (HB) and upper normal branch (NB). The model independent and dependent spectral analysis showed that during these time lags the structure of accretion disk significantly varied. Both eastern and western approaches were used to unfold the X-ray continuum and systematic changes were observed in soft and hard spectral components. These changes along with a systematic shift in the frequency of quasi-periodic oscillations (QPOs) made it substantially evident that the geometry of the accretion disk is truncated. Simultaneous energy spectral and power density spectral study shows that the production of the horizontal branch oscillations (HBOs) are closely related to the Comptonizing region rather than the disk component in the accretion disk. We found that as the HBO frequency decreases from the hard apex to upper HB, the disk temperature increases along with an increase in the coronal temperature which is in sharp contrast with the changes found in black hole binaries where the decrease in QPO frequency is accompanied by a decrease in the disk temperature and a simultaneous increase in the coronal temperature. We discuss the results in the context of re-condensation of coronal material in the inner region of the disk.

description: Thin film antiferromagnets have emerged as strong candidates for state-of-the-art spintronic applications, promising efficient spin current generation that is critical for the development of low power non-volatile electronics. Intrinsic spin current generation in thin films has been primarily studied in systems with interfacial symmetry breaking, surface spin current from a topological insulator state, or a bulk spin Hall effect in heavy metal systems such as W, Ta, or Pt. In general, the high symmetry of these nonmagnetic systems limits the spin Hall conductivity tensor components to that of a left-handed polarization texture around the applied current direction, with out-of-plane spin currents having only y polarization. In contrast, the reduced symmetry of non-collinear antiferromagnets allows for additional linear-response-driven spin conductivities, including longitudinal and out-of-plane spin currents with x,z polarization, though the measured effects so far have been small and non-tunable. Understanding the intrinsic origin of these out-of-plane spin currents with atypical polarization could enable new developments in low power non-volatile spin-based electronics. In this work, multi-component out-of-plane spin Hall conductivities are discovered in L12 ordered antiferromagnetic PtMn3 thin films that are uniquely generated in the non-collinear state. The maximum spin torque efficiencies (Js/Je ~ 0.3) are found to be significantly larger than in Pt (~ 0.1), a canonical spin Hall effect material. Additionally, the spin Hall conductivities in the non-collinear state exhibit an orientation-dependent anisotropy, which can be used to select for a dominant component. The work presented here demonstrates symmetry control through the magnetic lattice as a pathway to tailored functionality in magnetoelectronic systems.

description: Boundary value problems for integrable nonlinear evolution PDEs formulated on the half-line can be analyzed by the unified method introduced by one of the authors and used extensively in the literature. The implementation of this general method to this particular class of problems yields the solution in terms of the unique solution of a matrix Riemann-Hilbert problem formulated in the complex $k$-plane (the Fourier plane), which has a jump matrix with explicit $(x,t)$-dependence involving four scalar functions of $k$, called spectral functions. Two of these functions depend on the initial data, whereas the other two depend on all boundary values. The most difficult step of the new method is the characterization of the latter two spectral functions in terms of the given initial and boundary data, i.e. the elimination of the unknown boundary values. For certain boundary conditions, called linearizable, this can be achieved simply using algebraic manipulations. Here, we present an effective characterization of the spectral functions in terms of the given initial and boundary data for the general case of non-linearizable boundary conditions. This characterization is based on the analysis of the so-called global relation, on the analysis of the equations obtained from the global relation via certain transformations leaving the dispersion relation of the associated linearized PDE invariant, and on the computation of the large $k$ asymptotics of the eigenfunctions defining the relevant spectral functions.

Let X be an orbispace with perfect obstruction theory which admits an embedding in a smooth orbifold. One can then construct the virtual structure sheaf and the virtual fundamental class of X. In this paper we prove that Kawasaki's formula behaves well " with working virtually" on X in the following sense: if we replace the structure sheaves, tangent and normal bundles in the formula by their virtual counterparts then Kawasaki's formula stays true. Our motivation comes from studying the quantum K-theory of a complex manifold X, with the formula applied to Kontsevich' moduli spaces of genus 0 stable maps to X.

description: Stanley proved that, in characteristic zero, all artinian monomial complete intersections have the strong Lefschetz property. We provide a positive characteristic complement to Stanley's result in the case of artinian monomial complete intersections generated by monomials all of the same degree, and also for arbitrary artinian monomial complete intersections in characteristic two. To establish these results, we first prove an a priori lower bound on the characteristics that guarantee the Lefschetz properties. We then use a variety of techniques to complete the classifications.

description: Giant planets are more frequently found around stars above 1.5 Msun. This is also the threshold at which the disc dispersal mechanism changes from X-ray to FUV-driven. We model discs along the pre-m.s. evolution tracks of 1.5-3 Msun stars, investigating different stages of gas and dust loss, and show that ALMA will provide the needed empirical evidence to guide the Herbig Ae disc evolution theory.

On the non-planar beta-deformed N=4 super-Yang-Mills theory

description: The beta-deformation is one of the two superconformal deformations of the N=4 super-Yang-Mills theory. At the planar level it shares all of its properties except for supersymmetry, which is broken to the minimal amount. The tree-level amplitudes of this theory exhibit new features which depart from the commonly assumed properties of gauge theories with fields in the adjoint representation. We analyze in detail complete one-loop amplitudes and a nonplanar two-loop amplitude of this theory and show that, despite having only N=1 supersymmetry, two-loop amplitudes have a further-improved ultraviolet behavior. This phenomenon is a counterpart of a similar improvement previously observed in the double-trace amplitude of the N=4 super-Yang-Mills theory at three and four loop order and points to the existence of additional structure in both the deformed and undeformed theories.

description: We survey known results and present estimates and conjectures for the next-order term in the asymptotics of the optimal logarithmic energy and Riesz $s$-energy of $N$ points on the unit sphere in $\mathbb{R}^{d+1}$, $d\geq 1$. The conjectures are based on analytic continuation assumptions (with respect to $s$) for the coefficients in the asymptotic expansion (as $N\to \infty$) of the optimal $s$-energy.

description: We report the spectral and temporal variability properties of 18 candidate transient and potential transient (TC and PTC) sources detected in deep multi-epoch Chandra observation of the nearby elliptical galaxies, NGC 3379, NGC 4278 and NGC 4697. Only one source can be identified with a background counterpart, leaving 17 TCs + PTCs in the galaxies. Of these, 14 are in the galaxy field, supporting the theoretical picture that the majority of field X-ray binaries (XRBs) will exhibit transient accretion for >75% of their lifetime. Three sources are coincident with globular clusters (GCs), including two high-luminosity candidate black hole (BH) XRBs, with Lx=5.4E38 erg/s, and Lx=2.8E39 erg/s, respectively. The spectra, luminosities and temporal behavior of these 17 sources suggest that the transient population is heterogeneous, including neutron star (NS) and BH XRBs in both normal and high-rate accretion modes, and super soft sources containing white dwarf binaries. Our TC and PTC detections are noticeably fewer that the number expected from the populations synthesis (PS) models of Fragos et al. (2009), tailored to our new Chandra pointings of NGC 4278. We attribute this discrepancy to the PS assumption that the transient population is composed of NS XRBs, as well as differences between the statistical analysis and error estimates used in the model and our observations.

description: In the realm of automatic speech recognition (ASR), the quest for models that not only perform with high accuracy but also offer transparency in their decision-making processes is crucial. The potential of quality estimation (QE) metrics is introduced and evaluated as a novel tool to enhance explainable artificial intelligence (XAI) in ASR systems. Through experiments and analyses, the capabilities of the NoRefER (No Reference Error Rate) metric are explored in identifying word-level errors to aid post-editors in refining ASR hypotheses. The investigation also extends to the utility of NoRefER in the corpus-building process, demonstrating its effectiveness in augmenting datasets with insightful annotations. The diagnostic aspects of NoRefER are examined, revealing its ability to provide valuable insights into model behaviors and decision patterns. This has proven beneficial for prioritizing hypotheses in post-editing workflows and fine-tuning ASR models. The findings suggest that NoRefER is not merely a tool for error detection but also a comprehensive framework for enhancing ASR systems' transparency, efficiency, and effectiveness. To ensure the reproducibility of the results, all source codes of this study are made publicly available.

description: This dissertation studies three aspects of decision theory and behavioral economics, and their ap- plications. The first chapter, co-authored with Meng-Yu Liang and Simon Grant, studies a costly self- control model with limited willpower. In Gul and Pesendorfer (Econometrica 69(6):1403–1435, 2001), a decision-maker, when facing a choice among menus, evaluates each menu in terms of the maximum value of its commitment utility net of self-control costs. We extends the model such that this maximum is constrained by the condition that the cost of self-control cannot exceed the decision-maker’s stock of willpower w. Four of the five axioms of our characterization are as in their Theorem 3 except that the independence axiom is restricted to a subset of menus. We add one new axiom to regulate willpower as a limited (cognitive) resource in which the available “stock” does not vary across menus. In our characterization, choices within menus that satisfy WARP reveal a constant trade-off between commitment and temptation utilities. However, it is the discontinuity of preferences over menus (along with violations of WARP for choices within menus) that reveals w (measured in units of temptation utility), allowing for a behaviorally meaningful comparative measure of self-control across individuals. The second chapter, co-authored with Chen Zhao, Shaowei Ke and Zhaoran Wang, studies an axiomatic foundation for a class of neural-network models applied to decision-making under risk, called neural-network expected utility (NEU) models. Motivated by classic experimental find- ings, we weaken the independence axiom in a novel way. We show how to use simple neurons, referred to as behavioral neurons, in a NEU model to capture behavioral effects such as the cer- tainty effect and reference dependence. Empirically, we show that some simple NEU models with natural inter- pretation predicts better than existing theories such as expected utility theory and cumulative prospect theory out of sample, and that behavioral neurons help improve NEU models’ performance. The third chapter provides a micro-founded model to discuss the effects of decimal expression of prices. It applies the information cost function in Pomatto et al. [2020] to the model of Matějka [2015]. With this combination, this paper suggests that the inattentive consumer imperfectly uses leading digits as a signal to process information about prices. Further, this paper demonstrates that the monopolistic seller may reduce the sale price to change the leading digit to emphasize the sale to consumers with medium-level information capacity.

description: Information Security has always been an important aspect of consideration in daily life communication and with the advent of COVID-19 and communication, including sensitive data like corporate files, personal data etc., increasingly moving online, it has become more important than ever to provide secure communication methods. One such method is using encryption and steganography. Encryption is the process of converting ordinary plaintext data into an alternative form that is unreadable by perpetrators without authorization. Furthermore, steganography is the practice of hiding a file, message, video, or image within another such file. In this paper, we introduce a web-application that will enable the user to encrypt the data in a file of his choice and then hide it within a picture or GIF. This will provide the layman an application that is easy to use to communicate securely, even without extensive technical knowledge. The encryption algorithm used will be the AES-256 algorithm and the steganographic algorithm will be Syndrome-Trellis Codes (STCs) for their high embedding efficiency. The results display that the system designed offers a significant security level.
