description: The proliferation of cloud data center applications and network function virtualization (NFV) boosts dynamic and QoS dependent traffic into the data centers network. Currently, lots of network routing protocols are requirement agnostic, while other QoS-aware protocols are computationally complex and inefficient for small flows. In this paper, a computationally efficient congestion avoidance scheme, called CECT, for software-defined cloud data centers is proposed. The proposed algorithm, CECT, not only minimizes network congestion but also reallocates the resources based on the flow requirements. To this end, we use a routing architecture to reconfigure the network resources triggered by two events: 1) the elapsing of a predefined time interval, or, 2) the occurrence of congestion. Moreover, a forwarding table entries compression technique is used to reduce the computational complexity of CECT. In this way, we mathematically formulate an optimization problem and define a genetic algorithm to solve the proposed optimization problem. We test the proposed algorithm on real-world network traffic. Our results show that CECT is computationally fast and the solution is feasible in all cases. In order to evaluate our algorithm in term of throughput, CECT is compared with ECMP (where the shortest path algorithm is used as the cost function). Simulation results confirm that the throughput obtained by running CECT is improved up to 3x compared to ECMP while packet loss is decreased up to 2x.

description: One of the potential approaches to achieving dependable system operation is to incorporate so-called “self-healing” mechanisms into system architectures and implementations. A previous workshop on this topic exposed a wide diversity of researcher perspectives on what self-healing systems really are. This paper proposes a taxonomy for describing the problem space for self-healing systems including fault models, system responses, system completeness, and design context. It is hoped that this taxonomy will help researchers understand what aspects of the system dependability problem they are (and aren’t) addressing with specific research projects.

description: We present a general formalism of multipole descriptions under the space-time inversion group. We elucidate that two types of atomic toroidal multipoles, i.e., electric and magnetic, are fundamental pieces to express electronic order parameters in addition to ordinary electric and magnetic multipoles. By deriving quantum-mechanical operators for both toroidal multipoles, we show that electric (magnetic) toroidal multipole higher than dipole (monopole) can become a primary order parameter in a hybridized-orbital system. We also demonstrate emergent cross-correlated couplings between electric, magnetic, and elastic degrees of freedom, such as magneto-electric and magneto(electro)-elastic couplings, under toroidal multipole orders.

description: To advance from milli-arcsecond to micro-arcsecond astrometry, time keeping capability and its comparison among different stations need to be improved and enhanced. The T2L2 (Time transfer by laser link) experiment under development at OCA and CNES to be launched in 2008 on Jason-2, allows the synchronization of remote clocks on Earth. It is based on the propagation of light pulses in space which is better controlled than the radio waves propagation. In this paper, characteristics are presented for both common view and non-common view T2L2 comparisons of clocks between China and France.

Examining the Use of Case-Crossover Design with Non-Transient Medication Exposures
Creators: name: Huang, Hsiao-Ching
Publisher: name: University of Illinois at Chicago
Year: 2024

description: Observational studies are an important study design in pharmacoepidemiology research especially when examining the safety of medications. The case-crossover design is a self-controlled study design that only include patients with outcome. This design has advantages like controlling for time-invariants confounders and avoiding biases from inappropriate control selection. By comparing the probability of exposure between different time points, the case-crossover determines whether patients were more likely to be exposed to a drug at a specific time period. The case-crossover design was first designed for transient exposures; however, recent literatures have showed the increase usage of case-crossover design on non-transient exposures. Non-transient exposures can reduce the precision and introduce biases to the effect estimates of case-crossover design. Recommendations to reduce the impact of these biases include expanding the risk and control window and adding a representative control group. With increased use of the case-crossover design, it is not clear how often it is used with non-transient exposures, how frequently the recommendations were applied, and the magnitude of bias introduced by different medication patterns. The objective of this dissertation was to better understand the impact of applying the case-crossover design to non-transient exposures and to examine ways to correct for biases that might be introduced. We conducted three studies to address this objective.

The first study was a systematic review on published case-crossover studies from 2015 to 2021. Our study found that using case-crossover design on non-transient medication remains prevalent and around 40% of them did not apply recommended methods to account for biases. The second study used group-based trajectory model to identify common adherence trajectory patterns of non-transient medication using Sodium-Glucose Transporter 2 (SGLT2) as example. The third study used simulation study to quantify bias from different non-transient medication patterns individually and combined. Moreover, we used a real-world example of SGLT2 and outcomes to further validate our results from simulation study. We found that case-crossover produced unbiased results from transient exposures. When evaluating prolonged exposures or a mixture of different medication patterns, case-time-control with longer risk and control windows resulted in unbiased estimates. The real-world example findings were consistent with the simulation. In this dissertation, we provided evidence that there is a lack of implementation for recommended methods on published case-crossover so that can lead to misguided results. Our simulation showed that it is problematic to use case-crossover design on non-transient exposures. If or when need to use case-crossover on non-transient exposures, researchers should apply appropriate methods.
Does Probability become Fuzzy in Small Regions of Spacetime?

description: In a recent paper, Buniy et al. have argued that a possible discretization of spacetime leads to an unavoidable discretization of the state space of quantum mechanics. In this paper, we show that this conclusion is not limited to quantum theory: in any classical, quantum, or more general probabilistic theory, states (i.e. probabilities or corresponding amplitudes) become discrete or fuzzy for observers, as long as time evolution is reversible and entropy is locally bounded. Specifically, we show that the Bekenstein bound suggests that probabilities in small closed regions of space carry an uncertainty inversely proportional to the the square root of the system's effective radius and energy.

description: The Mpemba effect occurs when a hot system cools faster than an initially colder one, when both are refrigerated in the same thermal reservoir. Using the custom built supercomputer Janus II, we study the Mpemba effect in spin glasses and show that it is a non-equilibrium process, governed by the coherence length ξof the system. The effect occurs when the bath temperature lies in the glassy phase, but it is not necessary for the thermal protocol to cross the critical temperature. In fact, the Mpemba effect follows from a strong relationship between the internal energy and ξthat turns out to be a sure-tell sign of being in the glassy phase. Thus, the Mpemba effect presents itself as an intriguing new avenue for the experimental study of the coherence length in supercooled liquids and other glass formers.

description: Hardware design is carried out at several different levels, with different issues, models, and design strategies at each level. Thus circuits, registers, instruction sets, and architectures are designed in terms of different components combined with different operators; the analysis techniques (indeed, what is analyzed), notations, and appropriate tools are correspondingly different. The same situation is true for software, except that the distinctions among levels - or even the existence of distinct levels - is not as widely recognized.

description: A new approach using a hyperbolic-equation system (HES) is proposed to solve for the electron fluids in quasi-neutral plasmas. The HES approach avoids treatments of cross-diffusion terms which cause numerical instabilities in conventional approaches using an elliptic equation (EE). A test calculation reveals that the HES approach can robustly solve problems of strong magnetic confinement by using an upwind method. The computation time of the HES approach is compared with that of the EE approach in terms of the size of the problem and the strength of magnetic confinement. The results indicate that the HES approach can be used to solve problems in a simple structured mesh without increasing computational time compared to the EE approach and that it features fast convergence in conditions of strong magnetic confinement.

description: Utilizing on-chip caches in embedded multiprocessor-system-on-a-chip (MPSoC) based systems is critical from both performance and power perspectives. While most of the prior work that targets at optimizing cache behavior are performed at hardware and compilation levels, operating system (OS) can also play major role as it sees the global access pattern information across applications. This paper proposes a cache-conscious OS process scheduling strategy based on data reuse. The proposed scheduler implements two complementary approaches. First, the processes that do not share any data between them are scheduled at different cores if it is possible to do so. Second, the processes that could not be executed at the same time (due to dependences) but share data among each other are mapped to the same processor core so that they share the cache contents. Our experimental results using this new data locality aware OS scheduling strategy are promising, and show significant improvements in task completion times.

description: Pattern mining in temporal databases is one of the challenging platform which holds attention when some ordered sequences are frequently occurred at different time instances in the dataset. We have found temporal patterns in humanoid robot dataset of HOAP-2 (Humanoid Open-Architecture Platform) which generates different motions through recurring sequences of various joint associations. For mining temporal patterns in that dataset we have proposed a method. This method uses FP-Temporal and SH(Soft-Hyperlinked)-Temporal mining algorithm as pattern growth methods for generating temporal association rules for various motion patterns of HOAP-2. Brief performance analysis shows that SH-Temporal is much efficient than FP-Temporal for such datasets and works significantly for mining sequentially associative temporal patterns in terms of temporal association rules.

description: Power dissipation during test is a major challenge in testing integrated circuits. Dynamic power has been the dominant part of power dissipation in CMOS circuits, however, in future technologies the static portion of power dissipation will outreach the dynamic portion. This paper proposes an efficient technique to reduce both dynamic and static power dissipation in scan structures. Scan cell outputs which are not on the critical path(s) are multiplexed to fixed values during scan mode. These constant values and primary inputs are selected such that the transitions occurred on non-multiplexed scan cells are suppressed and the leakage current during scan mode is decreased. A method for finding these vectors is also proposed. Effectiveness of this technique is proved by experiments performed on ISCAS89 benchmark circuits.

description: This paper enables symbolic ternary simulation of systems with large embedded memories. Each memory array is replaced with a behavioral model, where the number of symbolic variables used to characterize the initial state of the memory is proportional to the number of distinct symbolic memory locations accessed. The behavioral model provides a conservative approximation of the replaced memory array, while allowing the address and control inputs of the memory to accept symbolic ternary values. Memory state is represented by a list of entries encoding the sequence of updates of symbolic addresses with symbolic data. The list interacts with the rest of the circuit by means of a software interface developed as part of the symbolic simulation engine. This memory model was incorporated into our verification tool based on Symbolic Trajectory Evaluation. Experimental results show that the new model significantly outperforms the transistor level memory model when verifying a simple pipelined data path.

description: Stellar nucleosynthesis of heavy elements such as carbon allowed the formation of organic molecules in space, which appear to be widespread in our Galaxy. The physical and chemical conditions—including density, temperature, ultraviolet (UV) radiation and energetic particles—determine reaction pathways and the complexity of organic molecules in different space environments. Dense interstellar clouds are the birth sites of stars of all masses and their planetary systems. During the protostellar collapse, interstellar organic molecules in gaseous and solid phases are integrated into protostellar disks from which planets and smaller solar system bodies form. After the formation of the planets 4.6 billion years ago, our solar system, including the Earth, was subjected to frequent impacts for several hundred million years. Life on Earth may have emerged during or shortly after this heavy bombardment phase, perhaps as early as 3.90–3.85 billion years ago, but the exact timing remains uncertain. A prebiotic reducing atmosphere, if present, predicts that building blocks of biopolymers—such as amino acids, sugars, purines and pyrimidines—would be formed in abundance. Recent modelling of the Earth's early atmosphere suggests, in contrast, more neutral conditions (e.g. H2O, N2, CO2), thus, precluding the formation of significant concentrations of prebiotic organic compounds. Moreover, even if the Earth's atmosphere were reducing, the presence of UV photons would readily destroy organic compounds unless they were quickly sequestered away in rocks or in the prebiotic ocean. Other possible sources of organic compounds would be high temperature vent chemistry, although the stability of such compounds (bases, amino acids) in these environments remains problematic. Finally, organic compounds may have been delivered to the Earth by asteroids, comets and smaller fragments, such as meteorites and interplanetary dust particles.

description: Many fields of science and engineering require finding eigenvalues and eigenvectors of large matrices. The solutions can represent oscillatory modes of a bridge, a violin, the disposition of electrons around an atom or molecule, the acoustic modes of a concert hall, or hundreds of other physical quantities. Often only the few eigenpairs with the lowest or highest frequency (extremal solutions) are needed. Methods that have been developed over the past 60 years to solve such problems include the Lanczos [1,2] algorithm, Jacobi-Davidson techniques [3], and the conjugate gradient method [4]. Here we present a way to solve the extremal eigenvalue/eigenvector problem, turning it into a nonlinear classical mechanical system with a modified Lagrangian constraint. The constraint induces exponential inflationary growth of the desired extremal solutions.

description: It is quite important to enhance and control the optomechanically induced high-order sideband generation to achieve low-power optical comb and high-sensitivity sensing with an integratable structure. Here we present and analyze a proposal for enhancement and manipulation of optical nonlinearity and high-order sideband generation in a hybrid atom-cavity optomechanical system that is coherently driven by a bichromatic input field consisting of a control field and a probe field and works beyond the perturbative regime. Our numerical analysis with experimentally achievable parameters confirms that robust high-order sideband generation and typical spectral structures with non-perturbative features can be created even under weak driven fields. The dependence of the high-order sideband generation on the atomic parameters are also discussed in detail, including the decay rate of the atoms and the coupling parameter between the atoms and the cavity field. We show that the cutoff order as well as the amplitude of the higher order sidebands can be well tuned by the atomic coupling strength and the atomic decay rate. The proposed mechanism of enhancing optical nonlinearity is quite general and can be adopted to optomechanical systems with different types of cavity.

description: Assessing IC manufacturing process fluctuations and their impacts on IC interconnect performance has become unavoidable for modern DSM designs. However, the construction of parametric interconnect models is often hampered by the rapid increase in computational cost and model complexity. In this paper we present an efficient yet accurate parametric model order reduction algorithm for addressing the variability of IC interconnect performance. The efficiency of the approach lies in a novel combination of low-rank matrix approximation and multi-parameter moment matching. The complexity of the proposed parametric model order reduction is as low as that of a standard Krylov subspace method when applied to a nominal system. Under the projection-based framework, our algorithm also preserves the passivity of the resulting parametric models.

description: This paper proposes a diagnosis scheme aimed at reducing diagnosis time of distributed small embedded SRAMs (e-SRAMs). This scheme improves the one proposed in [A parallel built-in self-diagnostic method for embedded memory buffers, A parallel built-in self-diagnostic method for embedded memory arrays]. The improvements are mainly two-fold. On one hand, the diagnosis of time-consuming Data Retention Faults (DRFs), which is neglected by the diagnosis architecture in [A parallel built-in self-diagnostic method for embedded memory buffers, A parallel built-in self-diagnostic method for embedded memory arrays], is now considered and performed via a DFT technique referred to as the "No Write Recovery Test Mode (NWRTM)". On the other hand, a pair comprising a Serial to Parallel Converter (SPC) and a Parallel to Serial Converter (PSC) is utilized to replace the bi-directional serial interface, to avoid the problems of serial fault masking and defect rate dependent diagnosis. Results from our evaluations show that the proposed diagnosis scheme achieves an increased diagnosis coverage and reduces diagnosis time compared to those obtained in [A parallel built-in self-diagnostic method for embedded memory buffers, A parallel built-in self-diagnostic method for embedded memory arrays], with neglectable extra area cost.

description: In the Coulomb blockade regime of a ballistic quantum dot, the distribution of conductance peak spacings is well known to be incorrectly predicted by a single-particle picture; instead, matrix element fluctuations of the residual electronic interaction need to be taken into account. In the normalized random-wave model, valid in the semiclassical limit where the number of electrons in the dot becomes large, we obtain analytic expressions for the fluctuations of two-body and one-body matrix elements. However, these fluctuations may be too small to explain low-temperature experimental data. We have examined matrix element fluctuations in realistic chaotic geometries, and shown that at energies of experimental interest these fluctuations generically exceed by a factor of about 3-4 the predictions of the random wave model. Even larger fluctuations occur in geometries with a mixed chaotic-regular phase space. These results may allow for much better agreement between the Hartree-Fock picture and experiment. Among other findings, we show that the distribution of interaction matrix elements is strongly non-Gaussian in the parameter range of experimental interest, even in the random wave model. We also find that the enhanced fluctuations in realistic geometries cannot be computed using a leading-order semiclassical approach, but may be understood in terms of short-time dynamics.

description: The memory subsystem has always been a bottleneck in performance as well as significant power contributor in memory intensive applications. Many researchers have presented multi-layered memory hierarchies as a means to design energy and performance efficient systems. However, most of the previous work do not explore trade-offs systematically. We fill this gap by proposing a formalized technique that takes into consideration data reuse, limited lifetime of the arrays of an application and application specific prefetching opportunities, and performs a thorough trade-off exploration for different memory layer sizes. This technique has been implemented on a prototype tool, which was tested successfully using nine real-life applications of industrial relevance. Following this approach we have able to reduce execution time up to 60%, and energy consumption up to 70%.

description: For any set $\mathcal B\subseteq\mathbb N=\{1,2,\dots\}$ one can define its \emph{set of multiples} $\mathcal M_{\mathcal B}:=\bigcup_{b\in\mathcal B}b\mathbb Z$ and the set of \emph{$\mathcal B$-free numbers} $\mathcal F_{\mathcal B}:=\mathbb Z\setminus\mathcal M_{\mathcal B}$. Tautness of the set $\mathcal B$ is a basic property related to questions around the asymptotic density of $\mathcal M_{\mathcal B}\subseteq\mathbb Z$. From a dynamical systems point of view (originated by Sarnak) one studies $η$, the indicator function of $\mathcal F_{\mathcal B}\subseteq\mathbb Z$, its shift-orbit closure $X_η\subseteq\{0,1\}^{\mathbb Z}$ and the stationary probability measure $ν_η$ defined on $X_η$ by the frequencies of finite blocks in $η$. In this paper we prove that tautness implies the following two properties of $η$: (1) The measure $ν_η$ has full topological support in $X_η$. (2) If $X_η$ is proximal, i.e. if the one-point set $\{\dots000\dots\}$ is contained in $X_η$ and is the unique minimal subset of $X_η$, then $X_η$ is hereditary, i.e. if $x\in X_η$ and if $w$ is an arbitrary element of $\{0,1\}^{\mathbb Z}$, then also the coordinate-wise product $w\cdot x$ belongs to $X_η$. This strengthens two results from [Bartnicka et al. 2015] which need the stronger assumption that $\mathcal B$ has light tails for the same conclusions.

description: This paper gives an overview of a new technique, named pseudo-ring testing (PRT). PRT can be applied for testing wide type of random access memories (RAM): bit- or word-oriented and single- or dual-port RAM's. An essential particularity of the proposed methodology is the emulation of a linear automaton over Galois field by memory own components.

description: Strange quark contributions to neutrino(antineutrino) scattering are investigated on the nucleon level in the quasi-elastic region. The incident energy range between 500 MeV and 1.0 GeV is used for the scattering. All of the physical observable by the scattering are investigated within available experimental and theoretical results for the strangeness form factors of the nucleon. In specific, a newly combined data of parity violating electron scattering and neutrino scattering is exploited. Feasible quantities to be explored for the strangeness contents are discussed for the application to neutrino-nucleus scattering.

description: University education may cultivate independent study by design of supportive environments for students. Recent proliferation of generative AI tools has had a significant impact on this. The extent to which successfull scholarship is influenced by these tools is the subject of current research and the focus of this study. Tasks in the field of databases with different competence levels and didactic goals were solved by students with the help of GPT-3.5. Intellectual performance and success were then evaluated. The results show that integration of generative language models has the potential ...
Efficient Modeling of Memory Arrays in Symbolic Simulation

description: This paper enables symbolic simulation of systems with large embedded memories. Each memory array is replaced with a behavioral model, where the number of symbolic variables used to characterize the initial state of the memory is proportional to the number of memory accesses. The memory state is represented by a list containing entries of the form ác, a, dñ, where c is a Boolean expression denoting the set of conditions for which the entry is defined, a is an address expression denoting a memory location, and d is a data expression denoting the contents of this location. Address and data expressions are represented as vectors of Boolean expressions. The list interacts with the rest of the circuit by means of a software interface developed as part of the symbolic simulation engine. The interface monitors the control lines of the memory array and translates read and write conditions into accesses to the list. This memory model was also incorporated into the Symbolic Trajectory Evaluation technique for formal verification. Experimental results show that the new model significantly outperforms the transistor level memory model when verifying a simple pipelined data path.

description: In light of the rising ubiquity and accessibility of AI tools, software engineering curricula must be adapted in response, particularly with regards to coding education. We propose an extension to Bloom's Revised Taxonomy, enhanced to a second dimension that represents the scope and complexity of coding tasks. The path that a computer science study program typically follows can be mapped onto these dimensions, and evaluated in the context of generative AI tool use, which falls into three core stages. AI should be initially banned, then made an explicit part of coding education, and finally ...
First-principles investigation of elastic anomalies in niobium at high pressure and temperature

description: Niobium does not show any structure transition up to very high pressures. Nonetheless, by using density functional theory, we demonstrate in this work that it exhibits striking softening in elastic moduli C44 and C' at a pressure from 20 to 150 GPa. A novel anomaly softening in C44 from 275 to 400 GPa is also predicted. The physics behind these two anomalies is elaborated by electronic structure calculations, which revealed that they are actually different, with the first one directly relates to an underlying rhombohedral distortion whereas the latter originates in an electronic topological transition. The large magnitude of the softening leads to a remarkable elastic anisotropy in both the shear and the Young's moduli of Nb. Further investigation shows that thermo-electrons have an important role on these anomalies. This effect has not been noticed before. With increased electronic temperature, it is found that all anomalies (both the elastic softening and anisotropy) in Nb are gradually diminished, effectively giving rise to a temperature-induced hardening phenomenon.

description: Conventional cache models are not suited for real-time parallel processing because tasks may flush each other's data out of the cache in an unpredictable manner. In this way the system is not compositional so the overall performance is difficult to predict and the integration of new tasks expensive. This paper proposes a new method that imposes compositionality to the system?s performance and makes different memory hierarchy optimizations possible for multimedia communicating tasks when running on embedded multiprocessor architectures. The method is based on a cache allocation strategy that assigns sets of the unified cache exclusively to tasks and to the communication buffers. We also analytically formulate the problem and describe a method to compute the cache partitioning ratio for optimizing the throughput and the consumed power. When applied to a multiprocessor with memory hierarchy our technique delivers also performance gain. Compared to the shared cache case, for an application consisting of two jpeg decoders and one edge detection algorithm 5 times less misses are experienced and for an mpeg2 decoder 6.5 times less misses are experienced.

description: Demonstrators, such as model railways, are effective in providing real-world examples that help students to grasp abstract concepts in the engineering of embedded software. Although building such a demonstrator yourself can appear overwhelming, we argue how building your own improves your teaching of embedded software. We report on how we have achieved these improvements with a development process that lets our teaching co-evolve with our own demonstrator, share our main lessons learned, and invite educators to discuss remaining challenges.
