CAD algorithms and performance of Malibu : an FPGA with time-multiplexed coarse-grained elements
Creators: name: Grant, David
Publisher: name: University of British Columbia
Year: 2011

description: Modern Field-Programmable Gate Arrays (FPGAs) are used to implement a wide range of ever-larger circuits, many of which have both coarse-grained and fine-grained components. Past research into coarse-grained FPGAs optimized for such circuits have only demonstrated a 10% density advantage. In contrast, time-multiplexing of fine-grained FPGAs has demonstrated a 14x density improvement. This leaves an open question whether a time-multiplexed, coarse-grained FPGA can provide a similar density advantage. Even more important is whether the coarse-grained circuit structure can be exploited by Computer-Aided Design (CAD) tools to significantly reduce compile times. This thesis investigates a new type of FPGA in which coarse-grained, time-multiplexed resources are added to a traditional FPGA. Through time-multiplexing, density and compile time are improved. By retaining fine-grained logic and routing resources, performance does not suffer as much as in past attempts. This thesis also presents two CAD flows, M-CAD and M-HOT, to compile Verilog for this new FPGA. Both flows speed up compile times by more than 10x, which has not been demonstrated with any other flow (even flows that sacrifice quality). They can also achieve a circuit density greater than modern FPGAs, and can trade density for performance, something most FPGA CAD flows cannot do. At maximum density, M-HOT flow achieves a 26.1x compile time speedup, 2.5x the density, and 0.5x the performance of a commercial FPGA and CAD tool. At maximum performance, M-HOT achieves 1.0x density, and 0.7x performance. In contrast, M-CAD is a bit faster than M-HOT but achieves a lower quality result. In M-CAD, there are situations where the placer needs temporal information from the scheduler to make good decisions. Instead, M-HOT divides the circuit into heights to keep the integrated placement, routing, and scheduling problem tractable, but compile time suffers if there are too few heights. Although we show there is at most a theoretical 1.6x or 2.0x clock frequency improvement still remaining in M-HOT or M-CAD, respectively, the amount achievable may be far less. Future work should focus on improving the front-end synthesis, the coarse/fine-grained interface, and the coarse/fine-grained partitioning to provide higher quality input to the back-end CAD flow.

description: Mouse embryonic stem (ES) cells are derived from the inner cell mass of blastocyst stage embryos and are used primarily for the creation of genetically engineered strains through gene targeting. While some inbred strains of mice are permissive to the derivation of embryonic stem cell lines and are therefore easily engineered, others are nonpermissive or recalcitrant. Genetic engineering of recalcitrant strain backgrounds requires gene targeting in a permissive background followed by extensive backcrossing of the engineered allele into the desired strain background. The inbred mouse strain DBA/2J is a recalcitrant strain that is used as a model of many human diseases, including glaucoma, deafness and schizophrenia. Here, we describe the generation of germ-line competent ES cell lines derived from DBA/2J mice. We also demonstrate the utility of DBA/2J ES cells with the creation of conditional knockout allele for Endothelin-2 (Edn2) directly on the DBA/2J strain background.

description: Sorting algorithms are heavily used. Quicksort is one of the fastest comparison-based sorting algorithms. These days almost all computing devices have multiple processors. There is a strong need of finding efficient parallel versions of the most common algorithms that are widely used. The basic version of quick sort is sequential and uses only one pivot. Recently, Yaroslavsky has proposed a modified version of the quick sort that uses two pivots and runs much faster than the single-pivot quick sort. Since then Java has incorporated this dual-pivot quick sort into its standard library for sorting. Although there are many parallel versions of the original single-pivot quick sort, there is a very few for the dual-pivot. Those few parallel versions of the dual-pivot quick sorts are compared with standard sort functions, rather than the dual-pivot quick sort itself. In this paper, we provide a parallel version of the dual-pivot quick sort algorithm of Yaroslavsky and implement it in Java. For comparison, we run both in small number of parallel processors. The experimental results show that our algorithm runs significantly faster than the Yaroslavsky’s algorithm. Moreover, our algorithm performs gradually better as the number of processors and the input size increase.

description: We study the diffraction of Damon-Eshbach-type spin waves incident on a one-dimensional grating realized by micro slits in a thin permalloy film. By means of time-resolved scanning Kerr microscopy we observe unique diffraction patterns behind the grating which exhibit replications of the spin-wave field at the slits. We show that these spin-wave images, with details finer than the wavelength of the incident Damon-Eshbach spin wavelength, arise from the strongly anisotropic spin wave dispersion.

description: Network-optimized virtual assistant (NOVA) is a robot developed by Bandung Techno Park (BTP) that can interact with humans for various purposes, such as a receptionist robot. NOVA robot is still in development and one of the main focuses is adding face recognition features so that the robot can actively greet and interact with humans. Therefore, we propose a face recognition and tracking system based on neural networks. This system is developed using the Google FaceNet feature extraction method. Previously, face detection in NOVA robot was implemented by employing the multi-task cascaded convolutional networks (MTCNN) method, whereas face tracking on the system was realized by using the modification of the MOSSE object tracking method. However, we found that the implementation of MTCNN in NOVA robot cannot run better than 30 fps. Therefore, this paper aims to solve this issue by investigating conventional face detection methods that could outperform MTCNN in this regard. Tests conducted on the ChokePoint dataset demonstrates that the system with LBP can achieve 30.44 fps framerate with a precision of 95% and recall of 83%. The test results show that LBP is not only better than MTCNN in identifying faces but also more efficient to compute.

description: Background

The household is a recognized community reservoir for Staphylococcus aureus. This study investigated potential risk factors for intra-household S. aureus transmission, including the contribution of environmental contamination.

Methods

We investigated intra-household S. aureus transmission using a sample of multiple member households from a community-based case-control study examining risk factors for CA-MRSA infection conducted in Northern Manhattan. During a home visit, index subjects completed a questionnaire. All consenting household members were swabbed, as were standardized environmental household items. Swabs were cultured for S. aureus. Positive isolates underwent further molecular characterization. Intra-household transmission was defined as having identical strains among two or more household members. Multiple logistic regression was used to identify independent risk factors for transmission.

Results

We enrolled 291 households: 146 index cases, 145 index controls and 687 of their household contacts. The majority of indexes were Hispanic (85%), low income (74%), and female (67%), with a mean age of 31 (range 1–79). The average size of case and control households was 4 people. S. aureus colonized individuals in 62% of households and contaminated the environment in 54% of households. USA300 was the predominant clinical infection, colonizing and environmental strain. Eighty-one households had evidence of intra-household transmission: 55 (38%) case and 26 (18%) control households (P

description: A drought hit most of Norway, Sweden and Finland in 2002-03 with a considerable reduction in hydropower production – and a considerable increase in the price of electricity. In Sweden the second half of 2002 was one of the driest in hundred years, in southern Finland the precipitation in August 2002 – April 200l was less than half of the average. In general, droughts are neither frequent nor severe in northern Europe, but they do occur. In Finland the most serious 20th century drought occurred in 1940-42. Mean annual countrywide discharge was only 49% of long-term average in 1941 and 47% in 1942. These were the tow driest years in the whole 20th century. Some knowledge on droughts before the instrumental period can be inferred from tree ring-widths. Prolonged sequences of sever summer droughts took place in southern Finland in 933-945, 1173-1191, 1988-1402 and 1664-1680. Some indications of cycles corresponding to periods of approximately 23, 30 and 57 years have been detected. In the present climate, the ratio of winter low flows to summer low flows is less than 0.5 in northern Finland, but over 2.0 in southwestern parts of the country. Climate change may alter these values significantly. Increasing trends of winter flows have already been observed in southern and central Finland.

description: Birt-Hogg-Dube (BHD) is a tumor suppressor gene syndrome associated with fibrofolliculomas, cystic lung disease, and chromophobe renal cell carcinoma. In seeking to elucidate the pathogenesis of BHD, we discovered a physical interaction between folliculin (FLCN), the protein product of the BHD gene, and p0071, an armadillo repeat containing protein that localizes to the cytoplasm and to adherens junctions. Adherens junctions are one of the three cell-cell junctions that are essential to the establishment and maintenance of the cellular architecture of all epithelial tissues. Surprisingly, we found that downregulation of FLCN leads to increased cell-cell adhesion in functional cell-based assays and disruption of cell polarity in a three-dimensional lumen-forming assay, both of which are phenocopied by downregulation of p0071. These data indicate that the FLCN-p0071 protein complex is a negative regulator of cell-cell adhesion. We also found that FLCN positively regulates RhoA activity and Rho-associated kinase activity, consistent with the only known function of p0071. Finally, to examine the role of Flcn loss on cell-cell adhesion in vivo, we utilized keratin-14 cre-recombinase (K14-cre) to inactivate Flcn in the mouse epidermis. The K14-Cre-Bhdflox/flox mice have striking delays in eyelid opening, wavy fur, hair loss, and epidermal hyperplasia with increased levels of mammalian target of rapamycin complex 1 (mTORC1) activity. These data support a model in which dysregulation of the FLCN-p0071 interaction leads to alterations in cell adhesion, cell polarity, and RhoA signaling, with broad implications for the role of cell-cell adhesion molecules in the pathogenesis of human disease, including emphysema and renal cell carcinoma.

description: We present a comparison of our results from ground-based observations of asteroid (21) Lutetia with imaging data acquired during the flyby of the asteroid by the ESA Rosetta mission. This flyby provided a unique opportunity to evaluate and calibrate our method of determination of size, 3-D shape, and spin of an asteroid from ground-based observations. We present our 3-D shape-modeling technique KOALA which is based on multi-dataset inversion. We compare the results we obtained with KOALA, prior to the flyby, on asteroid (21) Lutetia with the high-spatial resolution images of the asteroid taken with the OSIRIS camera on-board the ESA Rosetta spacecraft, during its encounter with Lutetia. The spin axis determined with KOALA was found to be accurate to within two degrees, while the KOALA diameter determinations were within 2% of the Rosetta-derived values. The 3-D shape of the KOALA model is also confirmed by the spectacular visual agreement between both 3-D shape models (KOALA pre- and OSIRIS post-flyby). We found a typical deviation of only 2 km at local scales between the profiles from KOALA predictions and OSIRIS images, resulting in a volume uncertainty provided by KOALA better than 10%. Radiometric techniques for the interpretation of thermal infrared data also benefit greatly from the KOALA shape model: the absolute size and geometric albedo can be derived with high accuracy, and thermal properties, for example the thermal inertia, can be determined unambiguously. We consider this to be a validation of the KOALA method. Because space exploration will remain limited to only a few objects, KOALA stands as a powerful technique to study a much larger set of small bodies using Earth-based observations.

description: Understanding the context of suicidal behaviors is critical for effective suicide prevention strategies. Although suicide is an important topic for Asian Americans, there is limited information about what Asian Americans’ attitudes are towards suicide and their perceptions about the effectiveness of prevention efforts. These questions are critical to examine to provide foundational knowledge for determining how best to intervene. In this study, Asian American (n = 87) and White (n = 87) participants completed self-report indexes on their knowledge of depression and suicide (e.g., estimates of suicide rates), coping attitudes (e.g., help-seeking) and suicide prevention attitudes (e.g., usefulness of PSAs). The results indicate that in comparison to Whites, Asian Americans perceived suicidal behavior to be more common, perceived a stronger link between depression and suicide, less frequently endorsed help-seeking strategies, and reported more concern or distress after viewing a suicide prevention PSA. These preliminary results also suggest the possibility of cultural differences in perceptions of suicide prevention messages. The implications of these findings are discussed with a focus on providing recommendations for exploring suicide prevention efforts for Asian Americans.

description: We investigate density perturbations sourced by a curvaton with a generic energy potential. The key feature of a curvaton potential which deviates from a quadratic is that the curvaton experiences a non-uniform onset of its oscillation. This sources additional contributions to the resulting density perturbations, and we especially find that the non-Gaussianity parameter f_NL can become large with either sign no matter whether the curvaton dominates or subdominates the universe when it decays. Such non-quadratic curvaton potentials are required in order to produce a red-tilted density perturbation spectrum (without invoking large-field inflation), and are also motivated by explicit curvaton models based on microscopic physics. We further apply our generic results to the case where the curvaton is a pseudo-Nambu-Goldstone (NG) boson of a broken U(1) symmetry, and show that the resulting density perturbations are strongly enhanced towards the hilltop region of the energy potential, accompanied by a mild increase of the non-Gaussianity. Such hilltop NG curvatons can produce observationally suggested density perturbations under wide ranges of inflation/reheating scales, and further predict the non-Gaussianity of the density perturbations to lie within the range 10

description: We have identified and studied a sample of 151 FR IIs found in brightest cluster galaxies (BCGs) in the MaxBCG cluster catalog with data from FIRST and NVSS. We have compared the radio luminosities and projected lengths of these FR IIs to the projected length distribution of a range of mock catalogs generated by an FR II model and estimate the FR II lifetime to be 1.9 x 10^8 yr. The uncertainty in the lifetime calculation is a factor of two, due primarily to uncertainties in the ICM density and the FR II axial ratio. We furthermore measure the jet power distribution of FR IIs in BCGs and find that it is well described by a log-normal distribution with a median power of 1.1 x 10^37 W and a coefficient of variation of 2.2. These jet powers are nearly linearly related to the observed luminosities, and this relation is steeper than many other estimates, although it is dependent on the jet model. We investigate correlations between FR II and cluster properties and find that galaxy luminosity is correlated with jet power. This implies that jet power is also correlated with black hole mass, as the stellar luminosity of a BCG should be a good proxy for its spheroid mass and therefore the black hole mass. Jet power, however, is not correlated with cluster richness, nor is FR II lifetime strongly correlated with any cluster properties. We calculate the enthalpy of the lobes to examine the impact of the FR IIs on the ICM and find that heating due to adiabatic expansion is too small to offset radiative cooling by a factor of at least six. In contrast, the jet power is approximately an order of magnitude larger than required to counteract cooling. We conclude that if feedback from FR IIs offsets cooling of the ICM, then heating must be primarily due to another mechanism associated with FR II expansion.

description: Pneumonia is a virus, bacterium, and fungi infection disease which causes alveoli swelling and gets worse easily if it is not taken care of immediately. There are symptoms that can be recognized through x-ray images, for example the appearance of white mist in the lungs. A pneumonia classification system has already developed, but it still produced low accuracy. In this research we develop classification system by increasing the depth of CNN architecture using Residual Neural Network to improve accuracy from previous research. The dataset contains 2 classes which are pneumonia and normal, and trained to produce the best learning strategy with various scenarios. The model trained using data train that has been oversampling. The best scenario is achieved by ResNet152 architecture using dropout 0.5. This scenario achieved a result of 0.88 precision, 0.95 recall, 0.92 f1-score, and 0.89 of accuracy. The classification model on this research produces higher accuracy compared to the research of Enes Ayan, et.al. in 2019 which produced 0.87.

description: Vegetation is an important feature of many rivers. Vegetation along rivers produces high resistance to flow and, as a result, has a large impact on water levels in rivers and lakes. This paper investigates the effects of instream-unsubmerged vegetation (such as the reed-similar Kalmus) on flow resistance and velocity distributions. Artificial vegetation is used in the experimental study to simulate the Acorus Calmus L. Experimental tests have shown that resistance depends strongly on vegetation density and that the Manning resistance coefficient varies with the depth of flow. A simplified model based on concepts of drag is developed to evaluate the roughness coefficient (Manning's n) for unsubmerged vegetation. In vegetated channels the overall flow resistance is influenced significantly by the distribution pattern of vegetated beds. Within vegetation, the mean velocity decreases with flow for which the vegetative roughness increases with decreasing velocity and vertical turbulent transport of momentum is negligible as demonstrated by experiments.

description: We report $^{77}$Se-nuclear magnetic resonance (NMR) results down to sufficiently low temperatures under magnetic fields parallel to both the $ab$-plane and the c-axis in a paramagnetic/superconducting (PM/SC) phase of K$_x$Fe$_{2-y}$Se$_2$. The observation of anisotropy in the orbital part of the Knight shift results in the anisotropy of its spin part increasing on approaching the transition temperature. The anisotropy of the Korringa relation suggests the presence of the weak spin fluctuations with a finite wave vector $\bm{q}$, which induce the magnetic fluctuations along the ab-plane at the Se site. Such fluctuations do not correspond to the stripe $(π,0)$ correlation of the Fe moment observed in many Fe-based superconductors, and are not contradictory to weak $(π,π)$ correlations. The nuclear spin-lattice relaxation rate $1/T_1$ shows a field-independent $T_1T \sim const.$ behavior at low temperatures for $H \parallel ab$, which is attributed to the nonzero density of states at the Fermi level and can be explained by the sign-changing order parameter even for nodeless gaps. The temperature dependence of $1/T_1$ is reproduced well by nodeless models with two isotropic gaps or a single anisotropic gap. The obtained gap magnitude in the isotropic two-gap model is comparable to those obtained in the angle-resolved photoemission spectroscopy experiments.

We show that the introduction of a chlorophyll metabolite, a light-absorbing pigment widely consumed in human diets, to Caenorhabditis elegans results in animals whose fat mass can be modulated by exposure to light, despite the worm consuming the same amount of food. In the presence of the chlorophyll metabolite, exposing the worms to light increased adenosine triphosphate, reduced oxidative damage, and increased median life spans, without an effect on animal reproduction. Mice fed a dietary metabolite of chlorophyll and exposed to light, over several months, showed reductions in systemic inflammation as measured by plasma α-macroglobulin. We propose that dietary chlorophyll metabolites can enable mitochondria to use light as an environmental cue, by absorbing light and transferring the energy to mitochondrial coenzyme Q.

description: Manfaat diversifikasi dapat dioptimalkan dengan mengategorikan aset ke dalam kelas-kelas tertentu. Di dalam pasar keuangan, terdapat struktur hirarki antar saham dan dapat dianalisis dengan mengobservasi serangkaian harga saham yang saling berkorelasi. Penelitian terdahulu banyak berfokus pada dampak analisis klaster terhadap performa portofolio, namun sedikit yang meninjau sisi seleksi aset dalam benchmark-nya. Penelitian ini mengajukan tiga skenario alternatif seleksi aset untuk proses konstruksi portofolio berbasis klaster sebagai sudut pandang baru dalam penyusunan benchmark konstruksi portofolio. Dalam pelaksanaannya, digunakan ward’s method untuk melakukan klasterisasi terhadap saham berdasarkan data in-sample dari 606 perusahaan tercatat di BEI. Dilanjutkan dengan konstruksi portofolio dengan tangency portfolio sebagai preferensi portofolio optimal dan seleksi aset dengan tiga skenario alternatif. Performa portofolio diukur menggunakan rasio Sharpe dan rasio terhadap data out-sample. Analisis klaster yang dilakukan menunjukkan kualitas yang luar biasa dalam kelompokkelompok saham yang terbentuk. Portofolio dengan analisis klaster memberikan performa yang sangat baik, melebihi portofolio tanpa analisis klaster.

description: We study D2-branes on the K3-fibration P^4_(11222)[8] using matrix factorizations at the Landau-Ginzburg point and analyze their moduli space and superpotentials in detail. We find that the open string moduli space consists of various intersecting branches of different dimensions. Families of D2-branes wrapping rational curves of degree one intersect with bound state branches. The influence of non-toric complex structure deformations is investigated in the Landau-Ginzburg framework, where these deformations arise as bulk moduli from the twisted sectors.

description: A marginally trapped surface in the four-dimensional Minkowski space is a spacelike surface whose mean curvature vector is lightlike at each point. We introduce meridian surfaces of parabolic type as one-parameter systems of meridians of a rotational hypersurface with lightlike axis in Minkowski 4-space and find their basic invariants. We find all marginally trapped meridian surfaces of parabolic type and give a geometric construction of these surfaces.

description: Until recently, recommender systems have been applied in learning, such as to recommend appropriate courses. They are based on users’ ratings, learning history, or curriculum that provide relationship between courses. The last approach, however, can’t be applied to Massive Open Online Courses (MOOCs) that don’t maintain such information. Hence, course recommender systems for MOOCs must be based on other learners’ experience. This paper discusses such recommender systems. We apply Apriori Association Rule and the case study used in this study is the Canvas Network dataset and the HarvardX-MITx dataset. The proposed recommender system consists of a pre-processing to normalize data and reduce anomalous data, data cleaning to handle empty data, K-Modes clustering to group users, grouping registration transactions for filtering user registration transaction, and finally, rule formation using the Apriori Association Rule. The performance of the association rules obtained, a lift ratio evaluation metric is used. The experiments results show the best parameters in this study are 0.01 for minimum support and 0.6 for minimum confidence. With these two parameters, the number of rules and the average lift ratio value on the Canvas Network dataset are 110 rules and 19.055, while the HarvardX-MITx dataset is 48 rules and 3.662.

description: Monash Secure eResearch Platform (SeRP) is a secure environment for sharing research data for collaboration and analysis, within the control and governance of the data custodian. Monash SeRP allows the Data custodian or the delegated project manager (Data Custodian) to have visibility and control over how their data is being used by other approved researchers.Onboarding a project/registry is simple and straightforward. The project owner places a request to create a project. A consultant will then be in touch to discuss the requirements and create the project.Once a project is established and a dataset uploaded, a Data Custodian can allocate controlled access to this dataset, provide computing power and approved analytical tools to approved researchers, manage the controls of the environment including restricting access to the internet, restricting the importing of other data, authorise all removals of data and audit the usage of data and compute resources.

Revisiting Acceleration of Charged Grains in Magnetohydrodynamic Turbulence

description: We study the acceleration of charged grains by magnetohydrodynamics (MHD) turbulence in the interstellar medium (ISM). We begin with revisiting gyroresonance acceleration by taking into account the fluctuations of grain guiding center along a uniform magnetic field (i.e. nonlinear theory--NLT). We calculate grain velocities due to gyroresonance by fast MHD modes using the NLT for different phases of the ISM, and compare with results obtained using quasi-linear theory (QLT). We find for the parameters applicable to the typical ISM phases that the fluctuations of grain guiding center reduce grain velocities by less than 15 percent, but they can be important for more special circumstances. We confirm that large grains can be accelerated to super-Alfvenic velocities through gyroresonance. For such super-Alfvenic grains, we investigate the effect of further acceleration via transit time damping (TTD) by fast modes. We find that due to the broadening of resonance condition in the NLT, the TTD acceleration is not only important for the cosines of grain pitch angle relative to the magnetic field mu>V_{A}/v, but also for mu

description: Medical imaging plays a fundamental role in oncology and drug development, by providing a non-invasive method to visualize tumor phenotype. Radiomics can quantify this phenotype comprehensively by applying image-characterization algorithms, and may provide important information beyond tumor size or burden. In this study, we investigated if radiomics can identify a gefitinib response-phenotype, studying high-resolution computed-tomography (CT) imaging of forty-seven patients with early-stage non-small cell lung cancer before and after three weeks of therapy. On the baseline-scan, radiomic-feature Laws-Energy was significantly predictive for EGFR-mutation status (AUC = 0.67, p = 0.03), while volume (AUC = 0.59, p = 0.27) and diameter (AUC = 0.56, p = 0.46) were not. Although no features were predictive on the post-treatment scan (p > 0.08), the change in features between the two scans was strongly predictive (significant feature AUC-range = 0.74–0.91). A technical validation revealed that the associated features were also highly stable for test-retest (mean ± std: ICC = 0.96 ± 0.06). This pilot study shows that radiomic data before treatment is able to predict mutation status and associated gefitinib response non-invasively, demonstrating the potential of radiomics-based phenotyping to improve the stratification and response assessment between tyrosine kinase inhibitors (TKIs) sensitive and resistant patient populations.

description: This article presents a criterion for limiting source dimensions of the instantaneous point source model. The source dimensions are required for applying superposition of the point sources in space to represent the non-point sources. The criterion generates less than one percent error when compared to the existing finite source model. A comparison between the existing point and the finite source models is conducted. It is found that the finite source model does not give acceptable output at all times, if series distribution is used to compute the error function. The front and tail of the concentration breakthrough curve from the finite source model shows uncharacteristic output depending on the source dimension and the distance of the observation point. On the contrary, the point source model generates smooth breakthrough curves at all time.
