description: The JPEG2000 standard defines the discrete wavelet transform (DWT) as a linear space-to-frequency transform of the image domain in an irreversible compression. This irreversible discrete wavelet transform is implemented by FIR filter using 9/7 Daubechies coefficients or a lifting scheme of factorizated coefficients from 9/7 Daubechies coefficients. This work investigates the tradeoffs between area, power and data throughput (or operating frequency) of several implementations of the Discrete Wavelet Transform using the lifting scheme in various pipeline designs. This paper shows the results of five different architectures synthesized and simulated in FPGAs. It concludes that the descriptions with pipelined operators provide the best area-power-operating frequency trade-off over non-pipelined operators descriptions. Those descriptions require around 40% more hardware to increase the maximum operating frequency up to 100% and reduce power consumption to less than 50%. Starting from behavioral HDL descriptions provide the best area-power-operating frequency trade-off, improving hardware cost and maximum operating frequency around 30% in comparison to structural descriptions for the same power requirement.

description: A new Time Projection Chamber (TPC) is currently under development for the sPHENIX experiment at RHIC. The TPC will be read out using multistage GEM detectors on each end and will be divided into approximately 40 pad layers in radius. Each pad layer is required to provide a spatial resolution of ~250 microns, which must be achieved with a minimal channel count in order to minimize the overall cost of the detector. The current proposal is to make the pads into a zigzag shape in order to enhance charge sharing among neighboring pads. This will allow for the possibility to interpolate the hit position to high precision, resulting in a position resolution many times better than the 2mm pitch of the readout pads. This paper discusses various simulation studies that were carried out to optimize the size and shape of the zigzag pads for the readout board for the TPC, along with the technical challenges in fabricating it. It also describes the performance of the first prototype readout board obtained from measurements carried out in the laboratory using a highly collimated X-ray source.

description: In the context of the high risk of airborne transmission of COVID-19, the question of the production of particles while playing wind instruments is highly relevant. Therefore, in this study, 23 professional musicians played their instruments in a cleanroom in cleanroom-grade clothing. The most common orchestral wind instruments flute, oboe, clarinet, and trumpet were therefore chosen. Aerosol measurements using a laser particle counter were conducted to quantify the emission rate of respiratory particles. Orchestral excerpts as well as sustained tones in two dynamic levels were played. The emitted particles were mostly in a submicron size range. For all instruments besides the clarinet, an influence of the loudness of playing on the emission rate could be observed. The emission rates for all musical instruments were independent of the passages played. Flute and oboe showed similar emission rates but lower than the values for clarinet and trumpet. While playing a note with a small volume, the flute, oboe, and trumpet have a similar emission rate as found for speaking.

description: Based on transversality condition of gauge boson self-energy we have systematically constructed the general structure of the gauge boson two-point functions using four linearly independent basis tensors in presence of a nontrivial background, i.e., hot magnetized material medium. The hard thermal loop approximation has been used for the heat bath to compute various form factors associated with the gauge boson's two point functions both in strong and weak field approximation. We have also analyzed the dispersion of a gauge boson (e.g., gluon) using the effective propagator both in strong and weak magnetic field approximation. The formalism is also applicable to QED. The presence of only thermal background leads to a longitudinal (plasmon) mode and a two-fold degenerate transverse mode. In presence of a hot magnetized background medium the degeneracy of the two transverse modes is lifted and one gets three quasiparticle modes. In weak field approximation one gets two transverse modes and one plasmon mode. On the other hand, in strong field approximation also one gets the three modes in Lowest Landau Level. The general structure of two-point function may be useful for computing the thermo-magnetic correction of various quantities associated with a gauge boson.

description: In this study, polyethylene glycol (PEG), as a sacrificial agent, and gelatin containing graphene oxide (GO) are co-electrospun to prepare scaffolds. Based on pore size measurements, removal of PEG leads to an increase in the pore size of modified scaffolds, resulting in easier infiltration. Moreover, noticeable elastic modulus of GO increased the mechanical strength. Alizarin red staining indicated proliferation and differentiation of human bone marrow-derived mesenchymal stem cells seeded on the modified scaffolds. Thus, gelatin scaffold containing 0.5% GO with 20% PEG at the ratio of 80:20 for gelatin–PEG was selected as the optimal scaffold for bone tissue engineering approaches.

description: We start from an interpretation of the $BC_2$-symmetric "Type I" (elliptic Dixon) elliptic hypergeometric integral evaluation as a formula for a Casoratian of the elliptic hypergeometric equation, and give an extension to higher-dimensional integrals and higher-order hypergeometric functions. This allows us to prove the corresponding elliptic beta integral and transformation formula in a new way, by proving both sides satisfy the same difference equations, and that the difference equations satisfy a Galois-theoretical condition that ensures uniqueness of simultaneous solution.

description: One of the main bottlenecks when designing a network processing system is very often its memory subsystem. This is mainly due to the state-of-the-art network links operating at very high speeds and to the fact that in order to support advanced Quality of Service (QoS), a large number of independent queues is desirable. In this paper we analyze the performance bottlenecks of various data memory managers integrated in typical Network Processing Units (NPUs). We expose the performance limitations of software implementations utilizing the RISC processing cores typically found in most NPU architectures and we identify the requirements for hardware assisted memory management in order to achieve wire-speed operation at gigabit per second rates. Furthermore, we describe the architecture and performance of a hardware memory manager that fulfills those requirements. This memory manager, although it is implemented in a reconfigurable technology, it can provide up to 6.2Gbps of aggregate throughput, while handling 32K independent queues.

description: Quantitative susceptibility mapping (QSM) inevitably suffers from streaking artifacts caused by zeros on the conical surface of the dipole kernel in k-space. This work proposes a novel and accurate QSM reconstruction method based on a direct k-space interpolation approach, avoiding problems of over smoothing and streaking artifacts. Inspired by the recent theory of annihilating filter-based low-rank Hankel matrix approach (ALOHA), QSM reconstruction problem is formulated as deconvolution problem under low-rank Hankel matrix constraint in the k-space. To reduce the computational complexity and the memory requirement, the problem is formulated as successive reconstruction of 2-D planes along three independent axes of the 3-D phase image in Fourier domain. Extensive experiments were performed to verify and compare the proposed method with existing QSM reconstruction methods. The proposed ALOHA-QSM effectively reduced streaking artifacts and accurately estimated susceptibility values in deep gray matter structures, compared to the existing QSM methods. Our suggested ALOHA-QSM algorithm successfully solves the three-dimensional QSM dipole inversion problem without additional anatomical information or prior assumption and provides good image quality and quantitative accuracy.

A time-dependent Schrödinger equation for molecular core-hole dynamics

Year: 2018
Subjects: subject: Atomic Physics (physics.atom-ph)

description: X-ray spectroscopy is an important tool for the investigation of matter. X rays primarily interact with inner-shell electrons creating core (inner-shell) holes that will decay on the time scale of attoseconds to few femtoseconds through electron relaxations involving the emission of a photon or an electron. The advent of femtosecond x-ray pulses expands x-ray spectroscopy to the time domain and will eventually allow the control of core-hole population on timescales comparable to core-vacancy lifetimes. For both cases, a theoretical approach that accounts for the x-ray interaction while the electron relaxations occur is required. Here we describe a time-dependent framework, based on solving the time-dependent Schrödinger equation, that is suitable for describing the induced electron and nuclear dynamics.

description: The fundamental premise behind Moving Target Defense (MTD) is to create a dynamic and shifting system that is more difficult to attack than a static system because a constantly changing attack surface at least reduces the chance of an attacker finding and exploiting the weakness. However, MTD approaches are typically chosen without regard to other qualities of the system, such as performance or cost. This report explores the use of self-adaptive systems, in particular those based on the architecture of the running system. A systems software architecture can be used to trade off different quality dimensions of the system. In particular, this report describes the first steps in reasoning formally about MTD approaches, and elevating this reasoning to an architectural level, along three thrusts: (1) creating an initial catalog of MTD tactics that can be used at the architectural level, along with the impacts on security and other quality concerns, (2) using this information to inform proactive self-adaptation that uses predictions of tactic duration to improve the self-adaptation and (3) using stochastic multiplayer games to verify the the behavior of a variety of MTD scenarios, from uninformed to predictive-reactive. This work is applied in the context of the Rainbow self-adaptive framework.
Exploring Spoken Word Poetry as Critical Pedagogy in Nursing: A Focus on Disability Justice Education
Creators: name: Jamal-Eddine, Sabrina Ali
Publisher: name: University of Illinois at Chicago
Year: 2024

description: The provision of inequitable, substandard care for disabled patients is perpetuated by ableism and the utter absence of disability-related education within applied health sciences programs. The discrepancy between healthcare provider belief about disability and disabled peoples’ actual lived experiences of disability mandates the exploration of innovative pedagogies which humanize, center the voices of, and situate disabled patients as agents and experts of their own bodies and care. Spoken word poetry is embodied performance poetry that centers the stories, voices, and lived experiences of marginalized people through justice-oriented anti-oppression processes of critical education and liberation. Considering the theoretical alignment, this research study explores the praxis of spoken word poetry as a pedagogical tool in disability justice education for nursing students.

Employing a non-experimental cross-sectional design, qualitative descriptive methods, semi-structured in-depth focus group interviews, and reflexive thematic analysis, this study explored junior University of Illinois Chicago Bachelor of Science in Nursing (BSN) student perceptions of a non-traditional transformative spoken word poetry-supplemented pedagogical intervention in healthcare-oriented disability justice education to confront ableism and its impact on the care and livelihood of disabled patients. Data collection from 4 focus groups and 21 participants resulted in three themes and 11 subthemes capturing the following: BSN student participants’ shifts from medical to social model conceptualizations of disability; the pedagogy’s employment of affective empathy to bidirectionally humanize nursing students and disabled people; and imagined futures for spoken word poetry and disability justice in nursing education. Essential next steps for research include multiply marginalized disability community-engaged intervention development and feasibility pilot testing.
The Relevance of Human Rights and Human Capital Investment in the Implementation of Sustainable Development Goals (SDGs 3 and 4) in Nigeria
Creators: name: Hepzibah, Precious
Publisher: name: University of East London
Year: 2021

description: A human rights-based approach to development has found recent support from both State and Non-State Actors in the implementation of the Sustainable Development Goals in addressing development challenges in Nigeria and Africa. Since 2015, in Nigeria, the Sustainable Development Goals (SDGs) have attempted to create a renewed national conversation about the extent of the country‟s development challenges. These include poor human capital development/investment, infrastructure issues, and the lack of technological innovation, corruption and governance challenges, and the lack of proper government policies on development, which continue to hinder development progress. This thesis set out to define this approach, to examine the extent to which it is relevant, how it is applied, and to evaluate the barriers and challenges to the use of this approach in addressing poor human capital development challenges in Nigeria. This thesis is a library-based enquiry and adopts quantitative, inter-disciplinary, databases, and socio-legal approaches to understanding the context behind the poor human capital development challenges in Nigeria. Through examples this thesis shows how the approach works in practice, it went on to identify and discuss three human rights principles that play key roles to showcase its relevance in the implementation of Sustainable Development Goals SDGs 3 and 4 in Nigeria. This includes (1) participation and inclusion, (ii) non-discrimination and equality, and (iii) accountability. In terms of relevance, this thesis shows that the approach is related to the process of empowerment, and provides an opportunity for the use of legal instruments in defence of the marginalised or vulnerable groups such as women, girls and the Almajiris in the North. This thesis concludes that a human rights-based approach provides new avenues to address the issue of inequality by providing help to the marginalised or vulnerable groups such as women, girls, and the Almajiris in the North thereby ensuring equality between the North and South in terms of development outcomes.

description: The aim of this paper is to provide a solid mathematical discussion of the inverse problem in Magnetorelaxometry Imaging (MRXI), a currently developed technique for quantitative biomedical imaging using magnetic nanoparticles. We provide a detailed discussion of the mathematical modeling of the forward problems including possible ways to activate and measure, leading to a severely ill-posed linear inverse problem. Moreover, we formulate an idealized version of the inverse problem for infinitesimal small activation coils, which allows for a more detailed analysis of uniqueness issues. We propose a variational regularization approach to compute stable approximations of the solution and discuss its discretization and numerical solution. Results on synthetic are presented and improvements to methods used previously in practice are demonstrated. Finally we give an outlook to further questions and in particular experimental design.

description: We describe a new method that is both physically explicable and quantitatively accurate in describing the multifractal characteristics of intermittent events based on groupings of rank-ordered fluctuations. The generic nature of such rank-ordered spectrum leads it to a natural connection with the concept of one-parameter scaling for monofractals. We demonstrate this technique using results obtained from a 2D MHD simulation. The calculated spectrum suggests a crossover from the near Gaussian characteristics of small amplitude fluctuations to the extreme intermittent state of large rare events.

description: An important step in achieving robustness to run-time faults is the ability to detect and repair problems when they arise in a running system. Effective fault detection and repair could be greatly enhanced by run-time fault diagnosis and localization, since it would allow the repair mechanisms to focus adaptation effort on the parts most in need of attention. In this paper we describe an approach to run-time fault diagnosis that combines architectural models with spectrum-based reasoning for multiple fault localization. Spectrum-based reasoning is a lightweight technique that takes a form of trace abstraction and produces a list (ordered by probability) of likely fault candidates. We show how this technique can be combined with architectural models to support run-time diagnosis that can (a) scale to modern distributed software systems; (b) accommodate the use of black-box components and proprietary infrastructure for which one has neither a specification nor source code; and (c) handle inherent uncertainty about the probable cause of a problem even in the face of transient faults and faults that arise only when certain combinations of system components interact.

description: The capability of generating two intense, femtosecond x-ray pulses with controlled time delay opens the possibility of performing time-resolved experiments for x-ray induced phenomena. We have applied this capability to study the photoinduced dynamics in diatomic molecules. In molecules composed of low-Z elements, \textit{K}-shell ionization creates a core-hole state in which the main decay mode is an Auger process involving two electrons in the valence shell. After Auger decay, the nuclear wavepackets of the transient two-valence-hole states continue evolving on the femtosecond timescale, leading either to separated atomic ions or long-lived quasi-bound states. By using an x-ray pump and an x-ray probe pulse tuned above the \textit{K}-shell ionization threshold of the nitrogen molecule, we are able to observe ion dissociation in progress by measuring the time-dependent kinetic energy releases of different breakup channels. We simulated the measurements on N$_2$ with a molecular dynamics model that accounts for \textit{K}-shell ionization, Auger decay, and the time evolution of the nuclear wavepackets. In addition to explaining the time-dependent feature in the measured kinetic energy release distributions from the dissociative states, the simulation also reveals the contributions of quasi-bound states.

description: As digital content services gain importance in the mobile world, Digital Rights Management (DRM) applications will become a key component of mobile terminals. This paper examines the effect dedicated hardware macros for specific cryptographic functions have on the performance of a mobile terminal that supports version 2 of the open standard for Digital Rights Management defined by the Open Mobile Alliance (OMA). Following a general description of the standard, the paper contains a detailed analysis of the cryptographic operations that have to be carried out before protected content can be accessed. The combination of this analysis with data on execution times for specific algorithms realized in hardware and software has made it possible to build a model which has allowed us to assert that hardware acceleration for specific cryptographic algorithms can significantly reduce the impact DRM has on a mobile terminal's processing performance and battery life.

description: We report the identification of 10 transitions that support the detection of the small cyclic molecule ethylene oxide (c-C2H4O) in Sgr B2N. Although one of these transitions is severely blended, so that an accurate intensity and line width could not be determined, and two other lines are only marginally detected, we have done Gaussian fits to the remaining seven lines and have performed a rotation diagram analysis. Our results indicate a rotation temperature Trot = 18 K and a molecular column density N(c-C2H4O) = 3.3 × 1014 cm-2, corresponding to a fractional abundance relative to molecular hydrogen of order 6 × 10-11. This is a factor of more than 200 higher than the abundance for this molecule suggested by the "new standard" chemistry model of Lee, Bettens, & Herbst. This result suggests that grain chemistry might play an effective role in the production of c-C2H4O. No transitions of this molecule were detected in either Sgr B2M or Sgr B2NW.

description: This paper retraces the historical development of wireless LAN technology in the context of the pursuit of ever higher data rate, describes the significant technical breakthroughs that are now occurring, and speculates on future directions that the technology may take over the remainder of the decade. The challenges that these developments have created for low power operation are considered, as well as some of the opportunities that are presented to mitigate them. The importance of MIMO as an emerging technology for 802.11 is specifically highlighted, both in terms of the significant increase in data rate and range that it enables as well as the considerable challenge that it presents for the development of low power wireless LAN products.

description: Der Verkehr ist ein wachsendes Problem für den Klimaschutz, weil er nach wie vor fast vollständig auf fossilen Energieträgern beruht. Da insbesondere der Straßenverkehr viel Platz in Anspruch nimmt, wird zugleich der Ruf nach mehr Flächengerechtigkeit in der Stadt lauter. Daher nimmt der Druck zu, eine umfassende Verkehrswende einzuleiten. Dazu gehört ein Wechsel der Antriebstechnik mit dem Ziel der Dekarbonisierung, aber auch eine Änderung des Nutzungsverhaltens. Zugleich sind auch die Beharrungskräfte groß. Die Verkehrsinfrastruktur und die Siedlungs- und Lebensweisen eines großen Teils der Gesellschaft wurden seit Jahrzehnten auf das private Automobil hin ausgerichtet. Es gibt also eine mehrfache hohe Pfadabhängigkeit. Eine Verkehrswende geht weit über eine Antriebswende hinaus. Sie ist mit einem grundlegenden stadt- und siedlungsräumlichen Umbau verbunden. Dafür braucht sie veränderte rechtliche und steuerliche Rahmenbedingungen und einen umfassenden Kulturwandel. Realistischerweise beginnt die Verkehrswende mit kleinen Schritten. Es gilt zunächst in Pilotversuchen und Experimenten Erfahrungen zu sammeln und alternative Mobilitätszukünfte zu illustrieren. Prerequisite for effective climate protection: The traffic turnaround in the cities - Transport is a growing problem for climate protection, because it is still almost entirely based on fossil fuels. Since road traffic, in particular, takes up a lot of space, the call for more space justice in the city is becoming louder. This is why there is increasing pressure to initiate a comprehensive traffic turnaround. This includes not only a change in drive technology with the aim of decarbonisation, but also a change in user behaviour. At the same time, the inertia is also great. The transport infrastructure as well as settlement structure and life style of a large part of society have been geared towards the private automobile for decades. There is therefore a high path dependence. A traffic turnaround goes far beyond a drive turn. It means a fundamental urban and settlement redevelopment.It needs a changed legal and fiscal framework and also a comprehensive cultural change. Realistically, the turnaround begins with small steps. The first step is to gather experience in pilot projects and experiments and to illustrate alternative mobility solutions.

description: Software architecture allows us to make many decisions about a software system and analyze it even before it has been implemented, so as to make planned development possible. Similarly, architecture-based software evolution planning makes planned evolution possible by allowing us to make many decisions about the evolution of a software system and to analyze its evolution at the level of architecture design before software evolution is realized. In this paper, we develop a framework for architecture-based software evolution planning. It is done by defining various foundational terms and concepts, providing a taxonomy of software evolution plans, and then showing how to calculate values for various types of plans. By identifying and defining constituent foundational concepts, this conceptual framework makes precise the notion of ‘architecture-based software planning’. By developing a value-calculation framework for software evolution plans, it also provides a basis for concrete methods for designing and evaluating evolution plans

description: Estonian Teen Language Corpus (Eesti teismeliste keele korpus) is a corpus representing spoken and written language data, collected from Estonian teenagers (ages 9-18) between 2019-2023. The corpus consists of four types of files. Spoken language data is represented by .eaf and .tsv files (spoken_eaf.zip, spoken_tsv.zip), and contain transcriptions of recordings made of teenagers' spontaneous speech, where one participant recorded a conversation between themselves and another person or several other people. Transcriptions are annotated on different linguistic tiers, including words, morphology, language, etc (see teke_spoken_metadata.txt). The corpus version 1.0 contains transcriptions of 116 conversations, most around one hour in length. The corpus can be used for addressing various linguistic research questions, as well as training various language technological applications (e.g. speech recognition, dialogue systems). Written language data is made up of online chats between two teenagers (ages 10-17). Chats are represented by .tsv and .html files (chat_html.zip, chat_tsv.zip). The corpus version 1.0 includes 110 chats. Annotation includes language tags and abbreviations. All personal information has been anonymised. Estonian Teen Language Corpus is a product of several consequtive projects, which are further described here: https://teismelistekeel.ee/.
Mehr Bildung für einen besseren Klimaschutz ?

description: »All we need is the will to change...«, waren die Worte von Rajendra Kumar Payuri, dem ehemaligen Vorsitzenden des Weltklimarates, bei der Vorstellung des Sachstandsberichtes 2014. Obgleich das Problembewusstsein für Fragen des Umwelt- und Klimaschutzes zugenommen hat, musste man feststellen, dass das Bewusstsein allein nicht ausreicht, um Menschen zum Handeln zu bewegen und Veränderungsprozesse einzuleiten. Inzwischen kommen Fachleute überein, dass es kontinuierliche zielgruppengerechte Kommunikations- und Bildungsmaßnahmen mit Lösungsansätzen braucht, um ein gemeinsames verantwortungsvolles Handeln herbeizuführen. Dazu gehört eine Orientierung auf dem Weg in die Zukunft ebenso wie eine ehrliche Auseinandersetzung um Sorgen, über Lebensstile und Werte. Gemeinsame Zukunftsbilder sind wichtig, damit Klimaschutz Realität wird. More education for better climate protection ? - »All we need is the will to change…« were the words of Rajendra Kumar Payuri, the former chairman of the IPCC, at the presentation of the report 2014. Although awareness of environmental and climate issues in the last 30 years increased, it has been found that awareness alone is not enough to get people to act and initiate change processes. In the meantime, experts agree that in addition to innovative political actions, it requires continuous target-oriented communication and education measures, which include solutions, to come up with responsible behaviour of the society. This includes orientation for the futures as well as honest discussion about worries, life and values. Common visions for the future are important to realize climate protection.
A High Quality/Low Computational Cost Technique for Block Matching Motion Estimation

description: Motion estimation is the most critical process in video coding systems. First of all, it has a definitive impact on the rate-distortion performance given by the video encoder. Secondly, it is the most computationally intensive process within the encoding loop. For these reasons, the design of high-performance low-cost motion estimators is a crucial task in the video compression field. An adaptive cost block matching (ACBM) motion estimation technique is presented in this paper, featuring an excellent tradeoff between the quality of the reconstructed video sequences and the computational effort. Simulation results demonstrate that the ACBM algorithm achieves a slight better rate-distortion performance than the one given by the well-known full search algorithm block matching algorithm with reductions of up to 95% in the computational load.

Physical parameters and basis transformations in the Two-Higgs-Doublet model
Creators: name: Nishi, C. C.
Publisher: name: arXiv

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: A direct connection between physical parameters of general Two-Higgs-Doublet Model (2HDM) potentials after electroweak symmetry breaking (EWSB) and the parameters that define the potentials before EWSB is established. These physical parameters, such as the mass matrix of the neutral Higgs bosons, have well defined transformation properties under basis transformations transposed to the fields after EWSB. The relations are also explicitly written in a basis covariant form. Violation of these relations may indicate models beyond 2HDMs. In certain cases the whole potential can be defined in terms of the physical parameters. The distinction between basis transformations and reparametrizations is pointed out. Some physical implications are discussed.

Architectural Requirements for Computing with Coalitions of Resources

Subjects: subject: 80399 Computer Software not elsewhere classified
subject: FOS: Computer and information sciences

description: Widespread use of the Internet is enabling a fundamentally new approach to software development: computing through dynamically formed, task-specific, coalitions of distributed autonomous resources. The resources may be information, calculation, communication, control, or services. Unlike traditional software systems, the coalitions lack direct control over the incorporated resources, which are independently created and managed. Moreover, the resources may be transient, either because of the resource manager"s actions or because of service interruptions. Development tools for resource coalitions will require new degrees of autonomy and automation in order to identify, compose, and track the resources. An economically viable reward structure will be required to establish a rich population of available resources. Evaluation will require new models of adequacy rather than classical full correctness. Computing through resource coalitions will thus create novel architectural challenges and opportunities.
