Optimized high-order finite difference wave equations modeling on reconfigurable computing platform
Creators: name: Lu, Mi

Subjects: Applied Computer Science

description: Finite difference (FD) methods are the most prevalent numerical modeling algorithms for simulating linear wave propagation phenomena in geophysics, electromagnetics, and aero- or marine-acoustics applications. Unfortunately, evaluating time evolution for waves in large-scale 2D or 3D domains is computationally demanding and data-intensive. As such, its programs are often exclusively executed on high performance supercomputers. In this paper, we propose a solution to accelerate the execution of realistic wave field modeling problems on a baseline reconfigurable computing (RC) platform. By adopting appropriate high-order temporal and spatial FD schemes along with efficient on-chip data buffering structure, we alleviate external memory bandwidth bottleneck at the cost of increased floating point computations, which fortunately can be absorbed by the pipelined computing engine with negligible speed penalty. In this way, a balance point can always be reached where the utilization of onboard reconfigurable hardware resources and external memory bandwidth are all optimized. The desirable simplicity and scalability properties of our method make it compatible with most commercial RC platforms. Moreover, our implementation is consistent with the prevalent PC-Cluster systems and can achieve better price-performance ratio along with much lower power consumption.

description: We propose a novel method to reconstruct high-resolution three-dimensional mass maps using data from photometric weak-lensing surveys. We apply an adaptive LASSO algorithm to perform a sparsity-based reconstruction on the assumption that the underlying cosmic density field is represented by a sum of Navarro-Frenk-White halos. We generate realistic mock galaxy shape catalogues by considering the shear distortions from isolated halos for the configurations matched to Subaru Hyper Suprime-Cam Survey with its photometric redshift estimates. We show that the adaptive method significantly reduces line-of-sight smearing that is caused by the correlation between the lensing kernels at different redshifts. Lensing clusters with lower mass limits of $10^{14.0} h^{-1}M_{\odot}$, $10^{14.7} h^{-1}M_{\odot}$, $10^{15.0} h^{-1}M_{\odot}$ can be detected with 1.5-$σ$ confidence at the low ($z<0.3$), median ($0.3\leq z< 0.6$) and high ($0.6\leq z< 0.85$) redshifts, respectively, with an average false detection rate of 0.022 deg$^{-2}$. The estimated redshifts of the detected clusters are systematically lower than the true values by $Δz \sim 0.03$ for halos at $z\leq 0.4$, but the relative redshift bias is below $0.5\%$ for clusters at $0.4

description: In this paper, the authors give the definitions of a coprime sequence and a lever function, and describe the five algorithms and six characteristics of a prototypal public key cryptosystem which is used for encryption and signature, and based on three new problems and one existent problem: the multivariate permutation problem (MPP), the anomalous subset product problem (ASPP), the transcendental logarithm problem (TLP), and the polynomial root finding problem (PRFP). Prove by reduction that MPP, ASPP, and TLP are computationally at least equivalent to the discrete logarithm problem (DLP) in the same prime field, and meanwhile find some evidence which inclines people to believe that the new problems are harder than DLP each, namely unsolvable in DLP subexponential time. Demonstrate the correctness of the decryption and the verification, deduce the probability of a plaintext solution being nonunique is nearly zero, and analyze the exact securities of the cryptosystem against recovering a plaintext from a ciphertext, extracting a private key from a public key or a signature, and forging a signature through known signatures, public keys, and messages on the assumption that IFP, DLP, and LSSP can be solved. Studies manifest that the running times of effectual attack tasks are greater than or equal to O(2^n) so far when n = 80, 96, 112, or 128 with lgM = 696, 864, 1030, or 1216. As viewed from utility, it should be researched further how to decrease the length of a modulus and to increase the speed of the decryption.

3-D Face Recognition Based on Warped Example Faces
Creators: name: Lu, Mi
Publisher: name: figshare
Year: 2021
Subjects: subject: 80106 Image Processing
subject: FOS: Computer and information sciences

description: In this paper, we describe a novel 3-D face recognition scheme for 3-D face recognition that can automatically identify faces from range images, and is insensitive to holes, facial expression, and hair. In our scheme, a number of carefully selected range images constitute a set of example faces, and another range image is chosen as a “generic face.” The generic face is then warped to match each of the example faces in the least mean square sense. Each such warp is specified by a vector of displacement values. In feature extraction operation, when a target face image comes in, the generic face is warped to match it. The geometric transformation used in the warping is a linear combination of the example face warping vectors. The coefficients in the linear combination are adjusted to minimize the root mean square error. After the matching process is complete, the coefficients of the composite warp are used as features and passed to a Mahalanobis-distance-based classifier for face recognition. Our technique is tested on a data set containing more than 600 range images. Experimental results in the access-control scenario show the effectiveness of the extracted features.

description: The study of network and molecular properties of disease-related genes has served the double purpose of understanding disease mechanisms and identifying novel disease gene candidates. Here, we explored the classic (such as degree and betweenness) and cartographic network properties and the tolerance to deleterious germline variants of groups genes involved in different classifications of diseases across six different protein interaction networks (PINs). We found that the network properties of disease genes are mostly due to cancer genes. We then focused on more homogeneous disease categories, such as autosomal dominant and recessive Mendelian disease genes and cancer driver genes, and show that cancer drivers tend to occupy the most central roles in the PIN, not only in terms of number of connections but in the number of clusters they participate. They are significantly more sensitive than the average to deleterious germline variants. Genes associated to recessive Mendelian diseases tend to be enclosed within modules and are significantly more tolerant to likely deleterious variants than other disease genes and other genes in the network. Genes related to dominant Mendelian diseases occupy intermediate positions in the network and are less sensitive to likely deleterious germline variants, although still more than average. In summary, we show that different classifications of diseases condition the network and molecular properties of disease genes. Computational methods aimed at prioritization of candidate disease genes or at identification of cancer driver genes could benefit from our results to improve their performance.

description: This study focuses on a group of practitioners from a school district that adopted reform-oriented curriculum materials but later rejected them, partially due to the inclusion of alternative algorithms in the materials. Metaphors implicit in a conversation among the group were analysed to illuminate their perspectives on instructional issues surrounding alternative algorithms. Several possible sources of resistance to folding alternative algorithms into instruction were found, including the ideas that: successful learning does not involve struggling with mathematics, the teacher’s role in the classroom is primarily to present information, and that mathematics learning progresses according to a fixed sequence of levels.

This contribution introduces an approach for the operando analysis of interfaces using photoelectron spectroscopy employing a solid oxide electrochemical cell. The combined chemical and electronic information provided by the experiment reveals that not only chemical but also electrostatic boundary conditions are essential for interface stability. The approach is demonstrated using (anti‐)ferroelectric (Pb,La)(Zr,Sn,Ti)O₃ dielectrics.

description: Στόχος της εργασίας μας με τίτλο «Η έννοια της εξουσίας και η προβληματική της ελευθερίας στο έργο του John Locke και του John Stuart Mill» ήταν η παρουσίαση και η εξέταση των ιδεών των δύο φιλοσόφων όσον αφορά στα κομβικά φιλοσοφικά ερωτήματα σχετικά με την πολιτική εξουσία και την ελευθερία. Στο πλαίσιο λοιπόν αυτής της μεταπτυχιακής εργασίας και αξιοποιώντας τόσο τα κείμενα των δύο φιλοσόφων όσο και τη σχετική δευτερεύουσα βιβλιογραφία, ασχοληθήκαμε με την πολιτική θεωρία του John Locke και συγκεκριμένα με τις διαφορές μεταξύ της φυσικής κατάστασης και της πολιτικής κατάστασης που τη διαδέχθηκε. Αναλύσαμε επίσης την έννοια της πολιτικής εξουσίας στο πλαίσιο της πολιτικής κοινότητας. Αφιερώσαμε μέρος της έρευνάς μας και στην προσέγγιση της έννοιας της συγκατάθεσης, ως απαραίτητη προϋπόθεση για τη σύμπηξη της πολιτικής κοινωνίας καθώς και στη διερεύνηση της έννοιας της φυσικής, πολιτικής και φυσικά θρησκευτικής ελευθερίας. Σε ό,τι αφορά τον John Stuart Mill, η έρευνά μας επικεντρώθηκε στα χαρακτηριστικά του πολιτεύματος της Αντιπροσωπευτικής Δημοκρατίας καθώς και στο αίτημα του φιλοσόφου για την ελευθερία της σκέψης και έκφρασης, για την προστασία της ατομικότητας και την προστασία της ελευθερίας από κρατικές παρεμβάσεις.
description: The aim of our thesis entitled "The concept of power and the problem of freedom in the work of John Locke and John Stuart Mill» was the presentation and examination of the ideas of the two philosophers with regard to the core philosophical questions about the political power and freedom. Within the framework of this thesis and utilizing both the texts of both philosophers and the relevant secondary sources, we dealt with the political theory of John Locke and specifically with the differences between the physical situation and the political situation which succeeded. We also analyzed the notion of political power within the political community. We spent part of our research in the understanding of the concept of consent as a prerequisite for the concretion of civil society and in the exploration of the concept of physical, political and religious freedom. In regards to John Stuart Mill, our research focused on the characteristics of the constitution of representative democracy and the philosopher's request for freedom of thought and expression, protection of the individuality and protection of freedom from state interference.

description: Dynamic alliance formations have increased dramatically over the past decade for its adaptation to environmental change and market competition. However, many fail, while an even greater proportion perform poorly. The risk analysis of dynamic alliance will help enterprises to choose a coalition partner and make a reasonable benefit allocation plan. It’s also good for reducing the risk and keeping the stability of the alliance. Based on the interaction and feedback relationships between criteria and/or indices, an index system for evaluating the risk of dynamic alliance is developed. With the information uncertainty and inaccuracy being considered, a new hybrid model based on fuzzy analytic network process (FANP) and fuzzy technique for order performance by similarity to ideal solution (TOPSIS) is proposed. The local weights of criteria and indices are obtained by fuzzy preference programming (FPP), and the comprehensive weights are derived by FANP. According to fuzzy TOPSIS, an optimal alternative is chosen by the closeness coefficient based on the shortest distance from the positive and the farthest distance from the negative ideal solutions. Finally, a numerical case is given by the proposed method.

description: The derived categories of toric varieties admit semi-orthogonal decompositions coming from wall-crossing in GIT. We prove that these decompositions satisfy a Jordan-Holder property: the subcategories that appear, and their multiplicities, are independent of the choices made. For Calabi-Yau toric varieties wall-crossing instead gives derived equivalences and autoequivalences, and mirror symmetry relates these to monodromy around the GKZ discriminant locus. We formulate a conjecture equating intersection multiplicities in the discriminant with the multiplicities appearing in certain semi-orthogonal decompositions. We then prove this conjecture in some cases.

Developing countries remain a relatively small market for U.S. HVP exports, while their HVP exports to the United States have expanded. Developing countries are significant competitors in HVP trade and their export market share in the EC-12 and Japan is generally higher than the U.S. share. HVP market access to industrial countries is an important issue for the United States and developing countries in the 1990's.
Population in Fragments: Inclusion, Risk, and the Anticipatory Universality of Postcolonial Genomics
Creators: name: Bhan, Samiksha
Publisher: name: Zeitschrift für Ethnologie/Journal of Social and Cultural Anthropology
Year: 2024

description: In recent years, genomic medicine has invited critical attention for its potential to include diverse population groups and therefore expand the clinical relevance of global genome databases in diagnosing diseases. Population geneticists across the Global South demand being included in this process by translating their national populations into geneticized fragments that move back and forth between laboratories, databases and sites of diagnosis and care. Taking the case of postcolonial India, this article explores how the scientific universality of genomics becomes contested, only to produce an ‘anticipatory universality’ oriented towards public-health futures. Drawing on Ruha Benjamin’s concept of ‘postcolonial genomics’, my argument is three-fold. First, I critique analyses that have explained population genetic studies in India as an exercise in fostering nationalism, showing instead that geneticists are increasingly interested not in the ‘Indian’ population as a whole, but rather in its ‘fragments’. Second, through a case study of the Lambadas in Telangana, I show how the material formation of these fragments highlights the limits of genomic universality, where the haplotype is treated as the ultimate fact in tracing both ancestry and disease risk. Third, I argue that it is partly due to the financial dependence of postcolonial geneticists on state bureaucracies that they enact an ‘anticipatory universality’ for genomics, which, even if severely limited and often harmful in the present, promises to be universally applicable in the future.

Ambivalent Allies? Environmentalism and Science in Contemporary India
Creators: name: Werner, Hanna
Publisher: name: Zeitschrift für Ethnologie/Journal of Social and Cultural Anthropology
Year: 2024

description: Science played a crucial role in the early days of Indian nationalism. This has not changed since India’s independence. With recent political transformations, the significance of science has acquired a new dimension. Contemporary apologists of Hindu nationalism have recognized the value of appeals to science, whether they are trying to legitimize claims to supremacy or to prove that ancient Indian scriptures attest to the presence of ‘modern’ science at their time of writing. Such mobilizations of science oscillate between particularism and universalism, whereby calls to reject ‘western’ universalism as culturally specific and therefore limited live in tension with efforts to universalize ‘native’ achievements, thought of as always already modern.
Complicating matters, this tension cuts across fields and political camps. The appeal to science also serves the critics of Hindu nationalist aspirations, whether they challenge the ‘hindutvaization’ of environmentalism or seek to substantiate socioecological concerns scientifically. The problem: recourse to (allegedly universal) science not only tends to depreciate ‘non-science’ achievements, it also situates one’s claims in a hegemonic political discourse that privileges some voices and concerns over others.
In this article, I use the example of environmentalism to decipher the ambiguous role of science as a source of legitimacy in contemporary Indian politics, where it creates both friction and unexpected alignments. To conclude, I attempt to outline a timely ‘grammar of environmentalism’ capable of addressing these tensions.

The letters are equiprobable, but the scoring function is such that one letter has a larger score than the other. In this setting, we prove that the order of variance is linear in the common length. Optimal alignments constitute a generalization of longest common subsequences, they can be represented as optimal paths in a two-dimensional last passage percolation setting with dependent weights.

description: Purpose: Difficulties with written expression are an important consideration in the assessment and treatment of school-age children. This study evaluated how intermediate-grade children with and without written language difficulties fared on a writing task housed within the Hayes and Berninger (2014) writing process framework. Method: Sixty-four children completed a writing task whereby they planned, wrote, and revised a narrative story across 3 days. Children had extended time to produce an outline, first draft, and final copy of their story. Language transcription approaches were used to obtain measures reflecting writing productivity, complexity, accuracy, and mechanics, in addition to measures of planning and revision. Results: Results indicated that children with writing difficulties produced poorer quality stories compared with their peers yet were not significantly different across all measures. Children with typical development produced longer stories with better spelling accuracy. Writing process measures predicted significant amounts of variance in writing quality across the sample. Discussion: Writing should be considered as part of language assessment and intervention, whether as the sole language difficulty or alongside difficulties with speaking, listening, or reading in children with language-based learning difficulties. Implications for translation of research to practice and service delivery are provided.
Profile morphology and polarization of young pulsars

Subjects: subject: Astrophysics (astro-ph)

description: We present polarization profiles at 1.4 and 3.1 GHz for 14 young pulsars with characteristic ages less than 75 kyr. Careful calibration ensures that the absolute position angle of the linearly polarized radiation at the pulsar is obtained. In combination with previously published data we draw three main conclusions about the pulse profiles of young pulsars. (1) Pulse profiles are simple and consist of either one or two prominent components. (2) The linearly polarized fraction is nearly always in excess of 70 per cent. (3) In profiles with two components the trailing component nearly always dominates, only the trailing component shows circular polarization and the position angle swing is generally flat across the leading component and steep across the trailing component. Based on these results we can make the following generalisations about the emission beams of young pulsars. (1) There is a single, relatively wide cone of emission from near the last open field lines. (2) Core emission is absent or rather weak. (3) The height of the emission is between 1 and 10 per cent of the light cylinder radius.

description: We explore galaxy properties and their link with environment and clustering using a population of ~1000 galaxies formed in a high resolution hydrodynamic simulation of the Lambda CDM cosmology. At the redshift we concentrate on, z=1, the spatial resolution is 1.4 proper kpc/h and Milky-way sized disk galaxies contain ~10^5 particles within their virial radii. We include supermassive black hole accretion and feedback as well as a multiphase model for star formation. We find that a number of familiar qualitative relationships hold approximately between galaxy properties, for example, galaxies lie between two broad extremes of type, where ``late'' types tend to be smaller in size, have lower circular velocities, younger stars, higher star formation rates, larger disk to bulge ratios and lower Sersic indices than ``early types''. As in previous studies the stellar component of disk galaxies is not as rotationally supported as in observations. Bulges contain too much of the stellar mass, although disks do have scale lengths compatible with observations. The addition of black hole physics to the simulations does not appear to have an impact on the angular momentum results, nor do we find that it is affected in an identical simulation with significantly lower mass resolution. Despite this, we can profitably use the rank order of either disk to total ratio, Sersic index, or galaxy age to separate galaxies into morphological classes and examine the density-morphology relation and morphology dependence of clustering. We find that while at redshift z=0, the well known preponderance of early types in dense environments is seen, at z=1 the density-morphology relation becomes flatter and late type galaxies are even seen to have a higher clustering amplitude than early types (abridged).

Rational Sceptics: Contestations of Science and Conspiracy in the Czech Republic

Year: 2024

description: Covid-sceptics in the Czech Republic relate strongly to the idea of universal science. They understand this universality as emerging through the participation of ordinary citizens in scientific knowledge-making. Rather than then belonging solely to the experts, science ought to be democratic and accessible. This article describes several ways in which Czech Covid-sceptics contest the boundaries of science and devise their own theories, observations and experiences as scientific. I describe how Covid-sceptics mobilize their embodied experience of the pandemic as evidence and intertwine this embodied knowledge with narratives of universal science. By relating to the notion of the rational, educated and self-informing citizen, they are able to enter into a relationship with science even despite the lack of formal expertise. Scientific universality becomes a point of contestation through which alternative knowledge is linked to the imaginaries of ‘good science’ and scientific authority.

description: To meet the changes of internal and external environment, Enterprise Resources Planning (ERP) system needs to have a good flexibility. Flexibility is an indispensable request and is also a way that must be taken during the establishment process of ERP. Flexibility measurement is an important item for the implementation of ERP flexibility. According to the characteristics of ERP system, an index system for flexibility measurement of ERP system is presented with the interdependence and feedback relationships among criteria and/or indices being taken into account. Due to the vagueness and uncertainty information during the process of flexibility measurement, triangular fuzzy numbers are used to indicate the preference opinions of experts and decision makers. A flexibility measurement model of ERP system based on fuzzy analytic network process (FANP) is proposed. The local weights of criteria and indices are derived by fuzzy preference programming (FPP) method. An unweighted supermatrix based on the network structure of index system is developed, and the limit supermatrix is generated. The flexibility level of ERP system can be measured by the weights and scores of ERP. Finally, a case is given by the proposed method.

description: Working in a distributed environment offers challenges surpassing those of operating in a self-contained world. While references and objects can travel beyond known boundaries, it is still possible to maintain an adequate picture of the global situation: allowing identification and reclamation of unreachable objects while preventing the collection of reachable objects which are not locally referenced. This work describes the implementation of a global garbage detection scheme for Raven - an object-oriented distributed system developed at the University of British Columbia.
Camera Trapping Wolves and Ghosts: Sensing Universality in the Conservation Sciences
Creators: name: Kumpf, Desirée
Publisher: name: Zeitschrift für Ethnologie/Journal of Social and Cultural Anthropology
Year: 2024

description: This article examines how scientists sense the rewilding of wolves in Italy through camera traps. Specifically, I elaborate on two cases when footage of these elusive animals did not allow scientifically sound conclusions but instead lent itself to storytelling about the fragility of human–wolf entanglements. Turning ‘the haunted data’, they collect in the wild, into ghostly tales on social media or conservation blogs becomes an important way for scientists to engage with wider publics. Taking a processual view of how scientists work with camera traps – from setting them up to capturing imagery and eventually turning their data into stories – the article argues that the uncertain and unreliable imagery of camera traps allows scientists to sense and narrate the fragile interconnectedness between humans and other species. Such scientifically inspired stories are used explicitly to counter widespread opposition to rewilding. On the basis of this case study, the article explores the more general question of how disseminating a narrative of universal interconnection has become a central mission of contemporary conservation science.

description: Density functionals with asymptotic corrections to the long-range potential provide entry-level methods for calculations on molecules that can sustain charge transfer, but similar applications in Materials Science are rare. We describe an implementation of the CAM-B3LYP range-separated functional within the Vienna Ab-initio Simulation Package (VASP) framework, together with its analytical functional derivatives. Results obtained for eight representative materials: aluminum, diamond, graphene, silicon, NaCl, MgO, 2D h-BN and 3D h-BN, indicate that CAM-B3LYP predictions embody mean-absolute deviations (MAD) compared to HSE06 that are reduced by a factor of 6 for lattice parameters, 4 for quasiparticle band gaps, 3 for the lowest optical excitation energies, and 6 for exciton binding energies. Further, CAM-B3LYP appears competitive compared to ab initio G0W0 and Bethe-Salpeter equation (BSE) approaches. The CAM-B3LYP implementation in VASP was verified by comparison of optimized geometries and reaction energies for isolated molecules taken from the ACCDB database, evaluated in large periodic unit cells, to analogous results obtained using Gaussian basis sets. Using standard GW pseudopotentials and energy cutoffs for the plane-wave calculations and the aug-cc-pV5Z basis set for the atomic-basis ones, the MAD in energy for 1738 chemical reactions was 0.34 kcal mol-1, whilst for 480 unique bond lengths this was 0.0036 Å; these values reduced to 0.28 kcal mol-1 (largest error 0.94 kcal mol-1) and 0.0009 Å by increasing the plane-wave cuttoff energy to 850 eV.

Universality as Horizon: Aspirations and Geometries of Astrophysics in Africa
Creators: name: Nieber, Hanna
Publisher: name: Zeitschrift für Ethnologie/Journal of Social and Cultural Anthropology
Year: 2024

description: For astronomers in Africa, both amateurs and professionals, the universality of the scientific investigation of the universe holds out the promise of navigating inequalities on earth. Universality is attractive: it allows astronomers from Africa to enter the global field of science diplomacy and provides them with a discursive framework in which to combat the structural inequalities of participation. Rather than taking universality as a descriptor for science, this article is inspired by Paulin Hountondji’s formulation of universality as horizon and speculatively elaborates this metaphor. Drawing on two ethnographic case studies, one on the spatial geometry of a Malagasy amateur astronomer, the other on the crafting of a vision document by and for astronomers in Africa, the article explores how different notions of ‘horizon’ are evoked in each case. In so doing, the article engages with the temporal and spatial aspects of universality and shows how this concept can elicit hope, provide direction and enable an examination of position-based particularities.

description: The aim of the thesis was the study of the new regulatory framework applied to the function of financial institutions in Greece and especially to their recapitalization. In details, elements concerning the relationship between the Greek economic crisis and the financial system were mentioned. Afterwards, the new framework -in community and national level- that regulates the preventive supervision of financial institutions was presented, as well as the plan of the liquidity aid of Greek economy. Furthermore, the establishment and function of the Hellenic Financial Stability Fund (HFSF) was analyzed, which, according to the new framework, takes over an important role in the recapitalization of financial institutions. Finally, the procedure of granting capital reinforcement from HFSF according to Law 3864/2010 was presented, and specifically, the procedure of its activation and conditions were analyzed, as well as the participation of HSFS and individuals in the capital increase of financial institutions, the provision of the new titles and the rights of HFSF.
Rethinking Psychology in Africa: From Decolonizing to Universalizing Knowledge in an Emerging Field
Creators: name: Vorhölter, Julia

description: Inspired by broader calls to decolonize knowledge, psychologists in Africa have recently started debating the necessity and feasibility of creating a distinctly African psychology as a new academic discipline and field of practice. Some view this idea, whether sceptically or enthusiastically, as a primarily political move; others are more concerned with philosophical questions regarding the possibilities, and boundaries, of universal psychological knowledge. While critics warn of the risks of exoticizing and further marginalizing ‘African’ psychology from what they see as a universal discipline, proponents argue that mainstream ‘Western psychology’ has so far been harmful, or at best irrelevant, for Africans. My article engages with these recent debates by drawing on my fieldwork among psychotherapists in Uganda. I question conventional framings of psychotherapy as something external and foreign to ‘Africa’ that has been imposed by outsiders. Instead, I show how Ugandan therapists consider themselves part of a universal field of knowledge and how, through their efforts to make this knowledge relevant in Uganda, they actively engage in the production and negotiation of psy’s universality. Nevertheless, they are confronted by historical legacies and contemporary structural inequalities which limit how and where they can practice, and how their work is valued.

description: Abstract: Organisational resilience to GPU side-channel attacks has surfaced as a pressing requirement with the advent of high-performance computing and data-intensive applications. The increasing adoption of GPUs necessitates commensurate cybersecurity mechanisms to protect sensitive information and assure the proper functioning of computing components. This work investigates the implications of NIST’s Cybersecurity Framework 2.0 within risk management and governance considering GPU side-channel attacks. We provide an overview of prevalent threats against GPU accelerator systems in terms of timing attacks, power analysis as well as cache attacks. Subsequently, a dependable, secure shader execution architecture is specified based on current state-of-the-art solutions augmented by advanced mathematical formulas exploited to reduce risks caused by GPU side-channel attacks in practice. In this context, we show that resilience can be reached, especially when risk-aware management is combined with adaptive governance measures derived from NIST’s Cybersecurity Framework 2.0, processing regular updates quarterly or even more frequently using our methodology.

description: Manufacturing and operation of wireless systems require a practical solution for achieving low-power and high-performance when using advance communication apparatus such as that using multiple-input and multiple-output (MIMO). Often algorithm solutions achieve very high performance but over only in a narrow range of operating parameters. This paper presents a hardware design of MIMO detection that allows real-time switching between various algorithms and detection effort to achieve high performance over the wide-range of signal to noise ratio (SNR) found in realistic operating conditions. We illustrate a design with over 80% reduction in detection power that satisfies the required quality of service (QoS) in SNRs (Eb/No) as low as 8.7 dB.
Informed kmer selection for de novo transcriptome assembly

description: Transcriptome assembly is one of the important step in many RNA-seq workflows. Currently de bruijn graph based de novo transcriptome assembly algorithms is widely used for this. One of the important parameter in any assembly algorithms is the k-mer (substrings of length k). The assembly generted by merging assemblies from different kmer values leads to optimal result when compared with assemblies generated by single kmer value. But there is no investigation on avoiding kmer values which doesnt really effect the final assembly. Currently researchers choose random kmer values spread over the read length. This leads to sub-optimal results and wastage of computational time and resources.

We propose an algorithm named KREATION (Kmer Range EstimATION). The algorithms compares related assemblies and estimates the need of performing an additional kmer assembly. Based on a linear model fit, KREATION decides whether a kmer value beyond which no additional assembly is required. The algorithm was tested was datasets of differnet coverage and also with different assembly algorithms.  It is parameter free and also completely de novo.
A note on percolation on Z^d: isoperimetric profile via exponential cluster repulsion

description: We show that for all p>p_c(\Z^d) percolation parameters, the probability that the cluster of the origin is finite but has at least t vertices at distance one from the infinite cluster is exponentially small in t. We use this to give a short proof of the strongest version of the important fact that the isoperimetric profile of the infinite cluster basically coincides with the profile of the original lattice. This implies, e.g., that simple random walk on the largest cluster of a finite box [-n,n]^d with high probability has L^\infty-mixing time Θ(n^2), and that the heat kernel (return probability) on the infinite cluster a.s. decays like p_n(o,o)=O(n^{-d/2}). Versions of these results have been proven by Benjamini and Mossel (2003), Mathieu and Remy (2004), Barlow (2004) and Rau (2006). For general infinite graphs, we prove that anchored isoperimetric properties survive supercritical percolation, provided that the probability of the cluster of the origin being finite with large boundary decays rapidly; this is the case for a large class of graphs when $p$ is close to 1. As an application (with the help of some entropy inequalities), we give a short conceptual proof of a theorem of Angel, Benjamini, Berger and Peres (2006): the infinite percolation cluster of a wedge in \Z^3 is a.s. transient whenever the wedge itself is transient.
