Application of a Discontinuous Galerkin Method to Discretize Acoustic Perturbation Equations

Airframe noise of complex geometries, like e.g. high-lift airfoil configurations, may conveniently be computed on unstructured grids. A Discontinuous Galerkin Method (DGM) provides a robust, high-order accurate discretization of systems of partial differential equations like for example the Acoustic Perturbation Equations (APE) even on this type of grid. In particular, a DGM based on Lagrange polynomials may be used, since it enables simple and cheap truncation of flux terms. The goal of the work reported herein is to verify such a DGM. Therefore, the sound field of a monopole situated in a laminar boundary layer is computed. Computations are stable, free from spurious numerical oscillations, and show very good agreement with other computations and with theoretical results.
The global distribution of the time-average wind stress curl from NSCAT

Abstract The time-average wind stress curl field for the global ocean is computed from the wind retrievals of the NASA Scatterometer (NSCAT) mission spanning the period 1 October 1996–29 June 1997. Particular attention is paid to large-amplitude, small-scale “patchiness” in the average wind stress curl over the major ocean basins, and to long and narrow wind stress curl features that occur along ocean eastern boundary regions. The 9-month-average wind stress curl field from NSCAT is examined at 0.5°, 1°, and on a Gaussian grid consistent with T62 truncation in a spectral forecast model. The latter field is compared with the average wind stress curl field from NCEP analyses for the same period. Artifacts in the NCEP average overlap the regions of boundary wind stress curl extrema in the high-resolution averages from NSCAT. The artifacts are attributed to the effects of spectral truncation and tall near-coastal topography in the NCEP forecast model. Possible explanations are discussed for the boundary wind .
THE SPECTRAL THEOREM FOR UNBOUNDED NORMAL OPERATORS

self adjoint operator A has a unique positive self adjoint square root A1/2; and an arbitrary self adjoint operator A has a unique representation A = A+ ~ A~ with A+ and A" self adjoint and positive and the range of each contained in the null space of the other. Write ( T\ = (T*Γ) 1/2 and, for complex λ and r ^ 0, let E(\, r) be the null space projection of (| T — XI \ — r/) +. For compact subsets K of the complex plane E(K)= Λ and for any Borel set M, E{M) = V {E(K): K compact and K £ M) . It is shown that E is the unique spectral measure such that T = \xE(dX) .
Habitual Subjective Sleep Continuity is Not Associated With Fluid Intelligence: An Exploratory Study

The link between sleep and cognition is well-established, but the link between subjective sleep and fluid intelligence is poorly understood. The aim of this exploratory study was to examine the relationship between habitual subjective sleep continuity and fluid intelligence. In this study, a total of 56 healthy sleepers (Mage = 30.91 years; SDage = 12.93 years) completed two fluid intelligence (abstract reasoning and two-dimensional mental rotation) tasks after completing seven consecutive days of sleep diaries. Relationships between subjective sleep continuity (total sleep time [TST]; sleep efficiency [SE%]); wake after sleep onset (WASO) and sleep onset latency (SOL), and task accuracy and speed were assessed using Pearson correlations. Overall, there were no associations between subjective sleep continuity (TST, SE%, WASO, SOL) and either task accuracy or speed (adjusted p-values > 0.0125). Overall, habitual subjective sleep continuity and fluid intelligence may not be associated. These results should be replicated in larger samples.
Some Experimental Non-Zero Sum Games with Lack of Information About the Rules

A discussion of the relationship between the theory of games and experimental gaming is presented. This includes comments on games of indefinite length and lack of knowledge concerning the rules. Six simple games are constructed and examined in the light of four different solution concepts. These games were used in an experiment with a class of Yale seniors as the subjects. The results of these experiments are discussed. They appear to lend weight to the non-cooperative equilibrium concept of solution.
Vertically Stacked Millimeter-Wave LTCC Filters With Cavity-Mode Suppression for System-in-Package Application

This article presents a series of vertically stacked millimeter-wave (mm-wave) bandpass filters (BPFs) based on low-temperature cofired ceramic (LTCC) technology. First, a vertically stacked coupling topology with multiple ground planes is proposed for LTCC filters. As its benefits, the unwanted electric coupling between adjacent resonators is avoided, while the electric coupling to ground planes is enhanced, contributing to higher stopband suppression levels. Moreover, over 50% size reduction is also realized by using the vertical topology. Second, a common issue of high-frequency harmonics induced by an LTCC-based parallel-plate cavity is addressed in this work. If multiple ground planes are employed in LTCC circuits, the cavity resonances will be excited, weakening the stopband performance seriously for LTCC filters. To this end, the LTCC-based parallel-plate cavity is analytically investigated, and the suppression techniques are accordingly proposed by miniaturizing, staggering, or notching the ground planes. For demonstration, two 27-GHz LTCC BPFs are designed, fabricated, and measured. The results indicate an extremely small size of 0.132 mm2, a small insertion loss (IL) of 1.32 dB, and a wide stopband are all realized.
A New Wideband Triple-Band Filter using SIR

A triple-band bandpass filter based on tri-section step impedance resonator (SIR) is proposed to realize compact size with low return loss and wideband characteristic. The center frequencies of the proposed filter are 1.9/5.65/9.2 GHz, which can be used in wireless communication system. The absolute bandwidth of this triple-band bandpass filter is almost 1 GHz with 53% fractional bandwidth at −3 dB, and it has been shown that the performance of the second and the third frequency is improved greatly by two high impedances. For demonstration, the filter has been fabricated and the experimental results show the excellent agreements with theoretical simulation results.
A symbol-map wavelet zero-tree image coding algorithm

A improved SPIHT image compression algorithm called symbol-map zero-tree coding algorithm (SMZTC) is proposed in this paper based on wavelet transform. The SPIHT algorithm is a high efficiency wavelet coefficients coding method and have good image compressing effect, but it has more complexity and need too much memory. The algorithm presented in this paper utilizes two small symbol-maps Mark and FC to store the status of coefficients and zero tree sets during coding procedure so as to reduce the memory requirement. By this strategy, the memory cost is reduced distinctly as well as the scanning speed of coefficients is improved. Those comparison experiments for 512 by 512 images are done with some other zerotree coding algorithms, such as SPIHT, NLS method. During the experiments, the biorthogonal 9/7 lifting wavelet transform is used to image transform. The results of coding experiments show that this algorithm speed of codec is improved significantly, and compression-ratio is almost uniformed with SPIHT algorithm.
Identification of Small GTPases That Phosphorylate IRF3 through TBK1 Activation Using an Active Mutant Library Screen

Interferon regulatory factor 3 (IRF3) integrates both immunological and non-immunological inputs to control cell survival and death. Small GTPases are versatile functional switches that lie on the very upstream in signal transduction pathways, of which duration of activation is very transient. The large number of homologous proteins and the requirement for site-directed mutagenesis have hindered attempts to investigate the link between small GTPases and IRF3. Here, we constructed a constitutively active mutant expression library for small GTPase expression using Gibson assembly cloning. Small-scale screening identified multiple GTPases capable of promoting IRF3 phosphorylation. Intriguingly, 27 of 152 GTPases, including ARF1, RHEB, RHEBL1, and RAN, were found to increase IRF3 phosphorylation. Unbiased screening enabled us to investigate the sequence-activity relationship between the GTPases and IRF3. We found that the regulation of IRF3 by small GTPases was dependent on TBK1. Our work reveals the significant contribution of GTPases in IRF3 signaling and the potential role of IRF3 in GTPase function, providing a novel therapeutic approach against diseases with GTPase overexpression or active mutations, such as cancer.
Prediction of Wear Failure in Journalpin Bearings

Wear damage is a common failure in engine bearing shells. Wear failure induces changes in the bearing geometry and affects the oil film pressure and the durability of bearing shells. In this paper, wear failure in journalpin (main) bearings of a reciprocating engine is studied. Using a dynamic model, forces and torques in the journalpin bearings have been calculated and used in the analysis. To calculate the lubricating characteristics of the bearing, such as minimum oil film thickness and maximum oil film pressure, the Elasto-HydroDynamic (EHD) model that incorporate mass conservation algorithms is utilized. Wear failure in journalpin bearings of a reciprocating engine is assessed and the results are presented. Archard’s model is used as a wear model of journalpin-bearing material. The asperity interaction of two rough surfaces is considered by the boundary lubrication model. The results show that the wear rate at the initial stage of engine running is high. The results indicate that the main reason for wear in the journalpin bearings is the applied torque on the bearing, leading to edge wear. In a V-12 or 6Inline engine, journalpin bearing number 4 has the highest amount of torque applied and therefore has the highest amount of wear.
Mediterranean Matters: Revision of the Family Onchidorididae (Mollusca, Nudibranchia) with the Description of a New Genus and a New Species

The Mediterranean Sea hosts a great Nudibranchia diversity and has proved to be particularly intriguing in the case of the family Onchidorididae, a group of dorid nudibranchs that lately increased its diversity with the addition of one recently described Mediterranean species. The Onchidorididae family has a troubled systematic history to date, characterized by uncertainties and genera that are considered valid or not, according to the different authors. This confused taxonomy reflects the lack of a broad and comprehensive view on the phylogenetic relationships occurring between Onchidorididae members, an incorrect interpretation of the diagnostic morphological characters, and a poor knowledge of important biological aspects characterizing the different genera included in the family. To shed some light on the systematics of Onchidorididae, an integrative taxonomic revision was carried out involving morphological, ecological, and molecular analyses on an updated dataset. Mediterranean specimens and species were added to the dataset of the already known Onchidorididae and a new species from the Adriatic Sea (Central Mediterranean Sea) is described here. Furthermore, historical controversies are clarified due to the discovery of new important synapomorphies useful to define genera belonging to the Onchidorididae family and to describe a new genus. Finally, the taxonomic status of all the known Onchidorididae species is investigated and discussed, filling the gap of knowledge on neglected species.
Pengujian Model Pengaruh Tata Kelola TI Terhadap Transformasi Digital dan Kinerja Asuransi C

-The emergence of new technological disruptions, changes in stakeholder behavior, and the emergence of the COVID-19 pandemic have made many incumbent organizations accelerate their digital transformation (DT). However, many DT-related investments have not met expectations due to a lack of governance practices. Previous research has shown the impact of IT governance (ITG) on organizational performance. However, traditional ITG mechanisms are suspected not necessarily effective in controlling DT. There are knowledge gaps in exploring the influence of ITG on DT and organizational performance (OP). Therefore, this study aimed to examine the influence model of hybrid ITG (traditional and agile/adaptive) on DT and OP based on a balanced scorecard (BSC) perspective. The method used was a survey by distributing a Likert scale online questionnaire to 11 roles related to DT in Asuransi C and got 52 respondents. The data were then analyzed using Structural Equation Modeling (SEM) and the SmartPLS application. The results showed that both agile/adaptive and traditional ITG mechanisms positively affected DT with a t statistic value of 1.799/ 2.754. Likewise, TD has a positive and significant effect on OP with a t statistic value of 13.001.
Fine-scale anisotropy of the cosmic microwave background in a universe dominated by cold dark matter

The fine-scale anisotropy of the cosmic microwave background radiation has been studied in cosmological models with a scale-invariant primordial adiabatic density fluctuation spectrum that are dominated by cold, weakly interacting particles such as axions or photinos. Normalization of the present fluctuation spectrum to the observed galaxy distribution, equivalent to the assumptionn that mass and light are correlated on large scales, results in excessive temperature anisotropy when compared to a recent upper limit on 4.5 unless the density parameter . cap omega. /sub 0/ exceeds 0.4 (50 km s/sup -1/ Mpc/sup -1//H/sub 0/). Combining this result with the requirement that the universe be at least 13 billion years old, we conclude that if the cosmological constant is zero, 0.4 or approx. =H/sub 0/> or approx. =50 km s/sup -1/ Mpc/sup -1/.
Trajectory Tracking Control of a Quad-Rotor UAV

In order to solve the problem of trajectory tracking of the Quad-rotor UAV, a trajectory tracking control method based on rodrigues formula is proposed in this paper, which can transform the problem of position control to attitude control, thus we can solve the problem of the characteristics of nonlinear, coupled, multivariate and underactuated. A attitude stabilized controller is designed by the Rodrigues formula of rigid rotation. The Lyapunov stability analysis proved the stability of the controller. The simulation result proved that this approach method solve the problem of the trajectory tracking of the Quad-rotor UAV.
A New Technique for Measuring Impact‐broadened Radio Recombination Lines in Hii Regions: Confrontation with Theory at High Principal Quantum Numbers

New, low‐noise receivers have allowed detection, in several giant H ii regions, of Rydberg‐Rydberg transitions of hydrogen that cover a large range of Δn‐values in a single observing window. This, in turn, allows lines covering a large range in principal quantum number n to be detected simultaneously with the same antenna beam. We have employed a new frequency‐switching technique which allows a very precise determination of the line widths. We have used this technique with the NRAO 140 foot telescope to observe lines in W51 and Orion A near 6 GHz, with Δn‐values that vary by a factor of ∼21 (Δn = 1–∼21) and corresponding n‐values that vary by a factor of 2.7 (n = 102–274). By generating Voigt line profiles using Griem’s theory of impact broadening by electrons, inserting them into a telescope data file, and processing them in a manner identical to that of the telescope data, we have been able to examine how the observing and reduction techniques affect both the line widths and line areas as n increases. For n≤180,Δn≤6, our restored line widths and areas give densities of Ne = 2500 and 4000 cm−3 in W51 and Orion A, respectively. These densities are higher than reported previously with a 5′ beamwidth. For higher n‐values we are unable to fit our data using Griem’s theory. For n>180,Δn>6, our telescope‐measured line widths fall rapidly below predicted values, while the line areas simultaneously increase above predicted values. This behavior of the line area as the line widths decrease is inconsistent with Griem’s theory or an instrumental effect. Observations of Orion A at 17.6 GHz, with a 1. ′7 beamwidth, require a density in excess of Ne = 20,000 cm−3 to fit. Although the detected lines cover a range in n and Δn from 71 to 177 and 1 to 17, respectively, there is no evidence for a line width decrease at the high Δn‐values. We conclude from this that the line narrowing seen at 6 GHz is related to the principal quantum number.
Semi-Supervised CT Lesion Segmentation Using Uncertainty-Based Data Pairing and SwapMix

Semi-supervised learning (SSL) methods show their powerful performance to deal with the issue of data shortage in the field of medical image segmentation. However, existing SSL methods still suffer from the problem of unreliable predictions on unannotated data due to the lack of manual annotations for them. In this paper, we propose an unreliability-diluted consistency training (UDiCT) mechanism to dilute the unreliability in SSL by assembling reliable annotated data into unreliable unannotated data. Specifically, we first propose an uncertainty-based data pairing module to pair annotated data with unannotated data based on a complementary uncertainty pairing rule, which avoids two hard samples being paired off. Secondly, we develop SwapMix, a mixed sample data augmentation method, to integrate annotated data into unannotated data for training our model in a low-unreliability manner. Finally, UDiCT is trained by minimizing a supervised loss and an unreliability-diluted consistency loss, which makes our model robust to diverse backgrounds. Extensive experiments on three chest CT datasets show the effectiveness of our method for semi-supervised CT lesion segmentation.
Structural and Spectroscopic Properties of Isoconazole and Bifonazole—Experimental and Theoretical Studies

The paper compares the experimental FT-IR, UV-vis, and 1H NMR spectra of isoconazole and bifonazole with the density functional theory (DFT) calculations using different functionals. The results were compared with previously reported data related to their analogue, posaconazole. The analysis of calculated IR spectra with use of CAM-B3LYP (isoconazole) or B3LYP (bifonazole) functionals shows good accordance with the experimental IR spectrum. The best compatibility between the experimental and theoretical UV spectra was observed with the use of B3LYP or wB97XD functionals for isoconazole or bifonazole, respectively. The reason for the difference in the UV-vis spectra of isoconazole and bifonazole was discussed based on linear response time-dependent DFT and natural bond orbital methods. The calculated 1H NMR spectrum shows that the DFT formalism, particularly the B3LYP functional, give an accurate description of the isoconazole and bifonazole chemical shifts.
Do Information Processing Costs Matter to Regulators? Evidence from the U.S. Shadow Bank Supervision

This study examines the effect of reducing information processing costs on U.S. state regulators who supervise mortgage companies (i.e., “shadow banks”) . State regulators traditionally disclosed enforcement actions against mortgage companies only on their individual websites. A centralized repository introduced in 2012 assembled enforcement records across states in one place, substantially reducing a regulator’ s cost to learn about enforcements in other states. To isolate the incremental effect of the centralized repository, we manually collect enforcement records from all state regulators’ websites both before and after the introduction of the centralized repository. We find that enforcement records posted on the centralized repository significantly increase the probability of subsequent enforcement actions against the same firm in other states, suggesting that reducing information processing costs helps state regulators identify companies that engage in misconduct. Additional analyses show that the effect is stronger for records from state websites where information is harder to process and for state regulators with more limited resources. Last, we find that lenders approve significantly fewer loan applications (particularly from risky borrowers) in the non-enforcing states after their enforcement records are posted on the centralized repository, indicating that these lenders reduce credit supply in response to heightened regulatory scrutiny. robustness of The unit of observation company-state-period.

Tunneling Hot Electron Transistor Using GaAs/AlGaAs Heterojunctions

The first tunneling hot electron transistor (HET) using semiconductor heterojunctions has been achieved.

Transfer efficiency for hot electrons through 100 nm thick n-GaAs was measured as 0.28.
A new symmetry‐preserving Cartesian‐grid method for computing flow past arbitrarily shaped objects

This paper deals with a numerical method for solving the unsteady, incompressible Navier–Stokes equations in domains of arbitrarily shaped boundaries, where the boundary is represented using the Cartesian‐grid approach. We introduce a novel cut‐cell discretization, which preserves the symmetry of convection and diffusion. That is, convection is discretized by a skew‐symmetric operator and diffusion is approximated by a symmetric, positive‐definite coefficient matrix. The resulting semi‐discrete (continuous in time) system conserves the kinetic energy if the dissipation is turned off; the energy decreases if dissipation is turned on. The method is successfully tested for an incompressible, unsteady flow around a circular cylinder at Re=100. Copyright © 2005 John Wiley & Sons, Ltd.
From MMU to MPU: adaptation of the Pip kernel to constrained devices

This article presents a hardware-based memory isolation solution for constrained devices. Existing solutions target high-end embedded systems (typically ARM Cortex-A with a Memory Management Unit, MMU) such as seL4 or Pip (formally verified kernels) or target low-end devices such as ACES, MINION, TrustLite, EwoK but with limited flexibility by proposing a single level of isolation. Our approach consists in adapting Pip to inherit its flexibility (multiple levels of isolation) but using the Memory Protection Unit (MPU) instead of the MMU since the MPU is commonly available on constrained embedded systems (typically ARMv7 Cortex-M4 or ARMv8 Cortex-M33 and similar devices). This paper describes our design of Pip-MPU (Pip’s variant based on the MPU) and the rationale behind our choices. We validate our proposal with an implementation on an nRF52840 development kit and we perform various evaluations such as memory footprint, CPU cycles and energy consumption. We demonstrate that although our prototyped Pip-MPU causes a 16% overhead on both performance and energy consumption, it can reduce the attack surface of the accessible application memory from 100% down to 2% and the privileged operations by 99%. Pip-MPU takes less than 10 kB of Flash (6 kB for its core components) and 550 B of RAM.
