description: In this paper, we propose a new sub-grid scale parameterization for the ice discharge into the ocean through outlet glaciers and inspect the role of different observational and palaeo constraints for the choice of an optimal set of model parameters. This parameterization was introduced into the polythermal ice-sheet model SICOPOLIS, which is coupled to the regional climate model of intermediate complexity REMBO. Using the coupled model, we performed large ensemble simulations over the last two glacial cycles by varying two major parameters: a melt parameter in the surface melt scheme of REMBO and a discharge scaling parameter in our parameterization of ice discharge. Our empirical constraints are the present-day Greenland ice sheet surface elevation, the surface mass balance partition (ratio between total ice discharge and total precipitation) and the Eemian interglacial elevation drop relative to present day in the vicinity of the NEEM ice core. We show that the ice discharge parameterization enables us to simulate both the correct ice-sheet shape and mass balance partition at the same time without explicitly resolving the Greenland outlet glaciers. For model verification, we compare the simulated total and sectoral ice discharge with other estimates. For the model versions that are consistent with the range of observational and palaeo constraints, our simulated Greenland ice sheet contribution to Eemian sea-level rise relative to present-day amounts to 1.4 m on average (in the range of 0.6 and 2.5 m).

description: We confront the concordance (standard) model of cosmology, the spatially flat $Λ$CDM Universe with power-law form of the primordial spectrum with Planck CMB angular power spectrum data searching for possible smooth deviations beyond the flexibility of the standard model. The departure from the concordance cosmology is modeled in the context of Crossing statistic and statistical significance of this deviation is used as a measure to test the consistency of the standard model to the Planck data. Derived Crossing functions suggest the presence of some broad features in angular spectrum beyond the expectations of the concordance model. Our results indicate that the concordance model of cosmology is consistent to the Planck data only at 2 to 3$σ$ confidence level if we allow smooth deviations from the angular power spectrum given by the concordance model. This might be due to random fluctuations or may hint towards smooth features in the primordial spectrum or departure from another aspect of the standard model. Best fit Crossing functions indicate that there are lack of power in the data at both low-$\ell$ and high-$\ell$ with respect to the concordance model. This hints that we may need some modifications in the foreground modeling to resolve the significant inconsistency at high-$\ell$. However, presence of some systematics at high-$\ell$ might be another reason for the deviation we found in our analysis.

description: *CONTENT WARNING* Depictions of death, gore, and suicide

This thesis explores the works of horror manga artist Ito Junji and analyzes the ways in which Ito criticizes certain institutions and individuals within Japanese society. His criticisms bring to light the fact that many social institutions that were meant to benefit individuals have changed in their function and instead work to harm those it was set up to help. It also delves into Ito’s portrayal of children in horror and how they are granted agency in a genre that often treats them as objects.

description: Glycosaminoglycans (GAGs) are heterogeneous acidic polysaccharides involved in a range of biological functions. They have a significant influence on the regulation of cellular processes and the development of various diseases and infections. To fully understand the functional roles that GAGs play in mammalian systems, including disease processes, it is essential to understand their structural features. Despite having a linear structure and a repetitive disaccharide backbone, their structural analysis is challenging and requires elaborate preparative and analytical techniques. In particular, the extent to which GAGs are sulfated, as well as variation in sulfate position across the entire oligosaccharide or on individual monosaccharides, represents a major obstacle. Here, we summarize the current state-of-the-art methodologies used for GAG sample preparation and analysis, discussing in detail liquid chromatograpy and mass spectrometry-based approaches, including advanced ion activation methods, ion mobility separations and infrared action spectroscopy of mass-selected species.

description: This study assesses socioeconomic differences in handgrip strength among older adults age 50 years and over in six middle-income countries, focusing on the association with selected measures of intrinsic capacity. Cross-sectional nationally representative data from the WHO’s Study on global AGEing and adult health (SAGE) was used. Three-level linear hierarchical models examine the association of demographic, socioeconomic status and multimorbidity variables with handgrip strength; regression-based Relative Index of Inequality (RII) examines socioeconomic inequalities in handgrip strength; multilevel linear and logistic hierarchical regression models document the association between handgrip strength and five domains of intrinsic capacity: locomotion, psychological, cognitive capacity, vitality and sensory.   Age, sex, work status, nutritional status showed significant association with handgrip strength, an important biomarker of health among older adults, across countries. Socioeconomic differences in handgrip strength, are notable across all countries except South Africa. Further, handgrip strength showed significant association with measures of intrinsic capacity across five domains: locomotion, psychological, cognition, vitality and sensory. The significant association of handgrip strength with measures of intrinsic capacity, suggest handgrip strength as an important measure of health in old age. Life-course interventions to improve the handgrip strength will be useful for the overall wellbeing of older adults.

description: Electronic structure calculation of atoms and molecules, in the past few decades has largely been dominated by density functional methods. This is primarily due to the fact that this can account for electron correlation effects in a rigorous, tractable manner keeping the computational cost at a manageable level. With recent advances in methodological development, algorithmic progress as well as computer technology, larger physical, chemical and biological systems are amenable to quantum mechanical calculations than ever before. Here we report the development of a new method for accurate reliable description of atoms, molecules within the Hohenberg-Kohn-Sham density functional theory (DFT). In a Cartesian grid, atom-centered localized basis set, electron density, molecular orbitals, two-body potentials are directly built on the grid. We employ a Fourier convolution method for classical Coulomb potentials by making an Ewald-type decomposition technique in terms of short- and long-range interactions. One-body matrix elements are obtained from standard recursion algorithms while two-body counterparts are done by direct numerical integration. A systematic analysis of our results obtained on various properties, such as component energy, total energy, ionization energy, potential energy curve, atomization energy, etc., clearly demonstrates that the method is capable of producing quite accurate and competitive (with those from other methods in the literature) results. In brief, a new variational DFT method is presented for atoms and molecules, \emph{completely} in Cartesian grid.

description: Rotating convective turbulence is ubiquitously found across geophysical settings, such as surface and subsurface oceans, planetary atmospheres, molten metal planetary cores, magma chambers, and magma oceans. Depending on the thermal and material properties of the system, buoyant convection can be driven thermally or compositionally, where a Prandtl number ($Pr = ν/ κ_i$) defines the characteristic diffusion properties of the system, with $κ_i = κ_T$ representing thermal diffusion and $κ_i = κ_C$ representing chemical diffusion. These numbers vary widely for geophysical systems; for example, the liquid iron undergoing thermal-compositional convection in Earth's core is defined by $Pr_T \approx 0.1$ and $Pr_C \approx 100$, while a thermally-driven liquid silicate magma ocean is defined by $Pr_T \approx 100$. Currently, most numerical and laboratory data for rotating convective flows exists at $Pr = O(1)$; high $Pr$ rotating convection relevant to compositionally-driven core flow and other systems is less commonly studied. Here, we address this deficit by carrying out a broad suite of rotating convection experiments made over a range of $Pr$ values, employing water and three different silicone oils as our working fluids ($Pr = $ 6, 41, 206, and 993). Using measurements of flow velocities (Reynolds, $Re$) and heat transfer efficiency (Nusselt, $Nu$), a baroclinic torque balance is found to describe the turbulence regardless of Prandtl number so long as $Re$ is sufficiently large ($Re \gtrsim 10$). Estimated turbulent scales are found to remain close to onset scales in all experiments, a result that may extrapolate to planetary settings. Lastly, we use our data to build $Pr$-dependent predictive nondimensional and dimensional scaling relations for rotating convective velocities that can be applied across a broad range of geophysical fluid dynamical settings.

description: Problems in applying random-matrix theory (RMT) to nuclear reactions arise in two domains.

Is Iraqw an easy language to learn?

description: This chapter argues that as soon as large sections of the population are expected to follow education in a language that is not their first language, ease of language learning becomes a relevant consideration. This is now the case in Africa. But is it possible to be more precise in assessing ease or difficulty of language learning? In order to discuss that, the chapter looks at levels of language learning and proposes a new way to approximate the ease or difficulty of language learning for specific combinations of languages. In order to do that, it develops an innovative way of using the Automated Similarity Judgement Program (ASJP) and its associated database. This is done by benchmarking it to a US government scheme for determining ease or difficulty of language learning for specific language pairs. The chapter argues why there is a wider relevance to such a scheme: in Tanzania as well as in other parts of the world, educational systems are increasingly entrusted with the task of teaching large sections of the population a second or third language. However, what can we expect an educational system to achieve? This is discussed in the context of Iraqw and the Tanzanian educational situation and leads to a number of recommendations that are relevant for the Tanzanian situation. The chapter ends with a summary and some last conclusions.

description: The fact that the Earth climate is a highly complex dynamical system is well-known. In the last few decades a lot of effort has been focused on understanding how climate phenomena in one geographical region affects the climate of other regions. Complex networks are a powerful framework for identifying climate interdependencies. To further exploit the knowledge of the links uncovered via the network analysis (for, e.g., improvements in prediction), a good understanding of the physical mechanisms underlying these links is required. Here we focus in understanding the role of atmospheric variability, and construct climate networks representing internal and forced variability. In the connectivity of these networks we assess the influence of two main indices, NINO3.4 and the North Atlantic Oscillation (NAO), by calculating the networks from time-series where these indices were linearly removed. We find that the connectivity of the forced variability network is heavily affected by ``El Niño'': removing the NINO3.4 index yields a general loss of connectivity; even teleconnections between regions far away from the equatorial Pacific ocean are lost, suggesting that these regions are not directly linked, but rather, are indirectly interconnected via ``El Niño'', particularly on interannual time scales. On the contrary, in the internal variability network (independent of sea surface temperature forcing) we find that the links are significantly affected by NAO with a maximum in intra-annual time scales. While the strongest non-local links found are those forced by the ocean, we show that there are also strong teleconnections due to internal atmospheric variability.

description: Accurate detection and diagnosis of carious lesions is the prerequisite for application of the most effective caries management approach. However, the accuracy of proximal caries detection using visual-tactile assessment is limited. Additional diagnostic measures should therefore be performed to increase the validity of the diagnosis. Amongst various caries detection aids available, bitewing radiographs remain the gold standard for detection of proximal caries lesions. Here we describe a method for caries diagnosis using standardized bitewing holders. With this method the bitewing holders can be placed more precisely and reproducibly in the oral cavity. This approach increases accuracy of bitewing radiographs, which, due to the reproducible placement of the x-ray film, allows for monitoring of carious lesions long term.

description: We report discovery of a shell like structure G354.4+0.0 of size 1.6' that shows morphology of a shell supernova remnant. Part of the structure show polarized emission in NRAO VLA sky survey (NVSS) map. Based on 330 MHz, 1.4 GHz Giant Metrewave Radio Telescope (GMRT) observations and existing observations at higher frequencies, we conclude the partial shell structure showing synchrotron emission is embedded in an extended HII region of size ~4'. The spectrum of the diffuse HII region turns over between 1.4 GHz and 330 MHz. HI absorption spectrum shows it to be located more than 5 kpc away from Sun. Based on morphology, non-thermal polarized emission and size, this object is one of the youngest supernova remnants discovered in the Galaxy with an estimated age of about 100-500 years.

description: Purpose: To evaluate diffusion abnormalities of the retina and optic nerve in patients with central retinal artery occlusion (CRAO) using standard stroke diffusion-weighted magnetic resonance imaging (DWI). Methods: In this case-control study, DWI scans of patients with nonarteritic CRAO were retrospectively assessed for acute ischemia of the retina and optic nerve. Two neuroradiologists, blinded for patient diagnosis, randomly evaluated DWI of CRAO patients and controls (a collective of stroke and transient ischemic attack [TIA] patients) for restrictions of the retina and optic nerve. We calculated statistical quality criteria and analyzed inter-rater reliability using unweighted Kappa statistics. Results: 20 CRAO patients (60,6 ± 17 years) and 20 controls (60,7 ± 17 years) were included in the study. Sensitivity, specificity, positive and negative predictive values for retinal DWI restrictions were 75%/80%/79%/76% (reader 1) and 75%/100%/100%/80% (reader 2), respectively. Unweighted Kappa was κ = 0,70 (95% CI 0,48‑0,92), indicating "substantial" interrater reliability. In comparison, sensitivity, specificity, PPV and NPV (positive and negative predictive values) for restrictions of the optic nerve in CRAO were 55%/70%/65%/61% (reader 1) and 25%/100%/100%/57% (reader 2). Inter-rater reliability was "fair" with unweighted Kappa κ = 0,32 (95% CI 0,09‑0,56). Conclusions: Retinal diffusion restrictions were present in a majority of CRAO patients and detectable with reasonable sensitivity, high specificity and substantial inter-rater reliability. Further studies are necessary to study time dependency of retinal diffusion restrictions, improve image quality and investigate the reliability of retinal DWI to discern CRAO from other causes of acute loss of vision.

Creators: name: Mata Carlos, Francisco
Publisher: name: University of Nevada, Las Vegas
Year: 2022

description: The healing process of several medical conditions related to venous insufficiency and burn scar management can be improved by the proper application of pressure. Current practices for applying pressure to an extremity do not guarantee the consensus ideal interface pressures for such medical conditions. Applying a low pressure range (within 15 – 40 mm Hg) is challenging due to many factors, but especially because the actual pressure applied by a compression garment used on a patient is unknown. The proposed device, used to sense and display low pressure values, is described in detail throughout the chapters of this thesis.An electronic device was designed, fabricated, assembled, calibrated, and tested in order to deliver a small wearable electronic system which can measure and provide low pressure values inside the range of interest. The sensing unit is intended to be placed underneath the compression garment against the arm or leg of the subject and take force (which is then converted to pressure) and temperature readings. These readings are analyzed by the microcontroller and sent via Bluetooth to the smart phone application where they can be reviewed by the user to make appropriate adjustments to the applied pressure, if necessary. The purpose of the thermal sensor is to sample the skin temperature over a period of time and use the collected data to determine the potential presence of skin infections. The four major elements that complete this system are the sensor unit, the controlling unit, the Bluetooth module, and the smart phone application, which can be powered by a single 3.7V rechargeable battery lasting tens of hours without replacement. The system can be adapted to run for several days if timers are implemented. The test results conducted to the wearable gadget show exceptional linearity and accuracy within 1N range (75 mm Hg), providing a promising solution for sensing low pressure values.

description: AI has revolutionized the processing of various services, including the automatic facial verification of people. Automated approaches have demonstrated their speed and efficiency in verifying a large volume of faces, but they can face challenges when processing content from certain communities, including communities of people of color. This challenge has prompted the adoption of "human-in-the-loop" (HITL) approaches, where human workers collaborate with the AI to minimize errors. However, most HITL approaches do not consider workers' individual characteristics and backgrounds. This paper proposes a new approach, called Inclusive Portraits (IP), that connects with social theories around race to design a racially-aware human-in-the-loop system. Our experiments have provided evidence that incorporating race into human-in-the-loop (HITL) systems for facial verification can significantly enhance performance, especially for services delivered to people of color. Our findings also highlight the importance of considering individual worker characteristics in the design of HITL systems, rather than treating workers as a homogenous group. Our research has significant design implications for developing AI-enhanced services that are more inclusive and equitable.

description: Given a set of points, we define a minimum Steiner point tree to be a tree interconnecting these points and possibly some additional points such that the length of every edge is at most 1 and the number of additional points is minimized. We propose using Steiner minimal trees to approximate minimum Steiner point trees. It is shown that in arbitrary metric spaces this gives a performance difference of at most $2n-4$, where $n$ is the number of terminals. We show that this difference is best possible in the Euclidean plane, but not in Minkowski planes with parallelogram unit balls. We also introduce a new canonical form for minimum Steiner point trees in the Euclidean plane; this demonstrates that minimum Steiner point trees are shortest total length trees with a certain discrete-edge-length condition.

description: Traditional models of secondary level education run the risk of reinforcing maladaptive learning processes that persist long after successful graduation. With considerations to the opportunities presented in B.C.’s New Curriculum, this Process Paper addresses issues present in traditional face-to-face formats by incorporating alternative methods for content delivery and assessment considerations.One method for alternative delivery that has the potential to circumvent some of these maladaptive trends is to deliver content through Gamification, Game-Based Learning (GBL), and organize curriculum through patterns of feedback that are often present in video game design. These systems can be supported under the guidance of B.C.’s New Curriculum and blended-learning approaches. This paper details a potential framework for incorporating game design and is organized around a Critical Challenge Question- “How can Game Design Theories and Gaming Environments be implemented in Instructional Design to support learning at the Secondary level?” Based on a review of foundational and current research trends in both education and in-game design, the Major Project, as another Key Deliverable, seeks to deliver a research and evidence-based example English/Language Arts course constructed using the gaming and GBL principles explored within the paper itself.

description: Migraines are the most common cause of chronic pain. Effective, non-pharmacological strategies to reduce migraine load are needed. Exercise is an effective strategy, but it is unclear how exercise timing and temporal preference (chronotype) factors modulate the laudatory effects of exercise. Purpose: Determine the effects of; 1) time-of-day of exercise, and 2) exercise synchrony with one’s chronotype, on migraine load. Methods: Participants were 13 sedentary individuals with 8+ migraines/month (age = 30 ± 11 yrs, 167 ± 6 cm, 86 ± 28 kg). Participants were categorized into morning-/evening-types based on the Morning/Eveningness Questionnaire and instructed to complete 1 month of self-selected exercise in the morning or evening (3 sessions per week of 30-min/session at 60-70% of estimated HRmax) in a randomized cross-over design. Migraine burden was assessed before and after each month of exercise via questionnaires (Headache Impact Test [HIT-6], Migraine Disability Assessment Test [MIDAS]). Exercise timing (morning vs evening) as well as synchrony with chronotype (In-Sync (IS); morning-type exercising in the morning or an evening-type exercising in the evening vs Out-of-Sync (OOS); morning-type exercising in the evening and evening-type exercising in the morning).

description: Agonism plays a vital role in democratic dialogue by fostering diverse perspectives and robust discussions. Within the realm of online conflict there is another type: hateful antagonism, which undermines constructive dialogue. Detecting conflict online is central to platform moderation and monetization. It is also vital for democratic dialogue, but only when it takes the form of agonism. To model these two types of conflict, we collected Twitter conversations related to trending controversial topics. We introduce a comprehensive annotation schema for labelling different dimensions of conflict in the conversations, such as the source of conflict, the target, and the rhetorical strategies deployed. Using this schema, we annotated approximately 4,000 conversations with multiple labels. We then trained both logistic regression and transformer-based models on the dataset, incorporating context from the conversation, including the number of participants and the structure of the interactions. Results show that contextual labels are helpful in identifying conflict and make the models robust to variations in topic. Our research contributes a conceptualization of different dimensions of conflict, a richly annotated dataset, and promising results that can contribute to content moderation.

title: Carbon Fiber Coil Spring Characterization and Manufacturing
Creators: name: Madrazo, Cooper
Publisher: name: University of Nevada, Las Vegas

description: Helical coil springs are used in many mechanical design applications including industrial machines, devices, and vehicle suspension systems. It is desirable to minimize the weight of vehicle suspension systems as this can improve performance and handling. Most vehicle suspension coil springs are made from solid steel alloys or other metallic materials. Significant weight savings could be achieved if the metallic material were replaced by high performance fiber reinforced polymer composites. However, the coil spring geometry is a difficult manufacturing challenge for composite materials. The goal of this thesis was to investigate efficient and low-cost manufacturing methods to produce light-weight polymer composite springs. Theoretical analysis of carbon fiber-epoxy helical springs was performed to demonstrate that suitable spring performance characteristics could be achieved at a reduced weight compared to steel springs. Multiple manufacturing approaches were attempted to determine a method to effectively produce a helical carbon fiber spring. These processes involve producing a mandrel that acts as an internal tool to lay-up the fiber reinforcement, infuse the epoxy resin, and cure the composite part. Three complete composite springs were fabricated. The springs were initially tested in quasi-static compression to determine the effective spring constant and to determine the reproducibility of these properties between different manufacturing cycles. Compressive fatigue experiments were performed up to 162 cycles to determine if there would be any change in properties. There was a 1% change in spring length and 7% change in spring constant after 167 cycles of loading. The mean spring constant after cycling for the three springs was 221.9 N/cm (126.7 lb/in) with a variance of 1.15 N/cm (0.65 lb/in). The composite springs had a weight reduction of 73.13% when comparing the weight per length to a steel equivalent. Theoretical predictions of the spring constant were accurate to 2% of the experimental results.

description: The main goal of this work is to determine the properties of the optical counterpart to the INTEGRAL source IGR J21343+4738, and study its long-term optical variability. We present optical photometric BVRI and spectroscopic observations covering the wavelength band 4000-7500 A. We find that the optical counterpart to IGR J21343+4738 is a V=14.1 B1IVe shell star located at a distance of ~8.5 kpc. The Halpha line changed from an absorption dominated profile to an emission dominated profile, and then back again into absorption. In addition, fast V/R asymmetries were observed once the disc developed. Although the Balmer lines are the most strongly affected by shell absorption, we find that shell characteristics are also observed in He I lines. The optical spectral variability of IGR J21343+4738 is attributed to the formation of an equatorial disc around the Be star and the development of an enhanced density perturbation that revolves inside the disc. We have witnessed the formation and dissipation of the circumstellar disc. The strong shell profile of the Halpha and He I lines and the fact that no transition from shell phase to a pure emission phase is seen imply that we are seeing the system near edge-on.

title: Effects of Distributed Energy Resources on the Bulk Electric System
Creators: name: Loveday, Stryder

description: The traditional power grid was designed with a centralized resource distribution in mind, with a relatively small number of large power generation facilities supplying the vast majority of load. With recent efforts to further diversify the power grid as well as an increased interest in renewable energy sources, there has been an unprecedented amount of new DistributedEnergy Resources (DERs) added to the grid within the last decade. This often heavily influences the local demand where these resources are installed, often causing power to flow in ways not anticipated by the original design of the grid. This thesis reviews the potential effects of DERs on the Bulk Electric System (BES) with respect to reliability limits established by the North American Electric Reliability Corporation (NERC). There are numerous impacts to the system as a whole that have been observed, such as voltage deviations and unexpected MW and MVAR flow patterns. In addition to being a reliability concern, this can introduce additional operational costs on equipment such as regulating transformers, as well as capacitor and reactor banks. Alternatively, these DERs may be able to provide a significant amount of reactive and regulating capacity, reducing operational costs of regulating equipment if correctly managed. The study of these effects will utilize OpenDSS, a software package developed by EPRI for studying distribution networks. Additionally, MATLAB and the GridPV toolbox are utilized for analysis of the simulation data. The model under investigation is a series of modified IEEE 33-bus systems, adjusted to include varying amounts of distributed resources and connected to a transmission line model with an approximated generation source and load at each end. This method will allow exploration of how adjustments in DER permeation and configuration can affect the transmission system and adjacent distribution networks. A moderate amount of study has been performed on how DERs may impact the distribution systems supporting them, but considerably less work has been put towards investigating the effects on the larger transmission systems. DERs have also previously been aggregated into larger generation models for use on transmission system studies, but this approach risks becoming inaccurate as DER system complexity grows and the approximations become less valid. This work will be increasingly important as distributed resources begin to make up a larger portion of total resources connected to the network.
Transport in Charged Colloids Driven by Thermoelectricity

description: We study the thermal diffusion coefficient DT of a charged colloid in a temperature gradient, and find that it is to a large extent determined by the thermoelectric response of the electrolyte solution. The thermally induced salinity gradient leads in general to a strong increase with temperature. The difference of the heat of transport of coions and counterions gives rise to a thermoelectric field that drives the colloid to the cold or to the warm, depending on the sign of its charge. Our results provide an explanation for recent experimental findings on thermophoresis in colloidal suspensions.

The Call of the Wild: How Playfulness Influences Our Views of Wild Animals

description: The present qualitative study investigated the link between human playfulness as a personality trait, views of wild animals (wolves, crows, owls, and coyotes), and connectedness to nature. The link has not been previously investigated directly. Twenty-one participants deemed to be playful were interviewed about their playfulness, connectedness to nature, and views of wild animals. The link between the three was found to be tenuous at best, and connectedness to nature was established as a key mediator of playfulness regarding views of wild animals. Although not explicitly investigated, views of relationships to one’s animal nature appeared to be an important influence on connection to nature and views of wild animals. The understanding of how playfulness connects us to our instinctual nature, to other animals, and to the natural world is likely much more complicated than originally hypothesized.

Kleptography and Steganography in Blockchains

Publisher: name: Lancaster University

description: Despite its vast proliferation, the blockchain technology is still evolving, and witnesses continuous technical innovations to address its numerous unresolved issues. An example of these issues is the excessive electrical power consumed by some consensus protocols. Besides, although various media reports have highlighted the existence of objectionable content in blockchains, this topic has not received sufficient research. Hence, this work investigates the threat and deterrence of arbitrary-content insertion in public blockchains, which poses a legal, moral, and technical challenge. In particular, the overall aim of this work is to thoroughly study the risk of manipulating the implementation of randomized cryptographic primitives in public blockchains to mount kleptographic attacks, establish steganographic communication, and store arbitrary content. As part of our study, we present three new kleptographic attacks on two of the most commonly used digital signatures: ring signature and ECDSA. We also demonstrate our kleptographic attacks on two real cryptocurrencies: Bytecoin and Monero. Moreover, we illustrate the plausibility of hijacking public blockchains to establish steganographic channels. Particularly, we design, implement, and evaluate the first blockchain-based broadcast communication tool on top of a real-world cryptocurrency. Furthermore, we explain the detrimental consequences of kleptography and steganography on the users and the future of the blockchain technology. Namely, we show that kleptography can be used to surreptitiously steal the users' secret signing keys, which are the most valuable and guarded secret in public blockchains. After losing their keys, users of cryptocurrencies will inevitably lose their funds. In addition, we clarify that steganography can be used to establish subliminal communication and secretly store arbitrary content in public blockchains, which turns them into cheap cyberlockers. Consequently, the participation in such blockchains, which are known to store unethical content, can be criminalized, hindering the future adoption of blockchains. After discussing the adverse effects of kleptographic and steganographic attacks on blockchains, we survey all of the existing techniques that can defend against these attacks. Finally, due to the shortcomings of the available techniques, we propose four countermeasures that ensure kleptography and steganography-resistant public blockchains. Our countermeasures include two new cryptographic primitives and a generic steganographyresistant blockchain framework (SRBF). This framework presents a universal solution that deters steganography and practically achieves the right to be forgotten (RtbF) in blockchains, which represents a regulatory challenge for current immutable blockchains.

description: We investigate an effective relativistic equation of state at finite values of temperature and baryon chemical potential with the inclusion of the full octet of baryons, the Delta-isobars and the lightest pseudoscalar and vector meson degrees of freedom. These last particles have been introduced within a phenomenological approach by taking into account of an effective chemical potential and mass depending on the self-consistent interaction between baryons. In this framework, we study of the hadron yield ratios measured in central heavy ion collisions over a broad energy range and present the beam energy dependence of underlying dynamic quantities like the net baryon density and the energy density.
