description: Millimeter wave (mmW) communications is the key enabler of 5G cellular networks due to vast spectrum availability that could boost peak rate and capacity. Due to increased propagation loss in mmW band, transceivers with massive antenna array are required to meet link budget, but their power consumption and cost become limiting factors for commercial systems. Radio designs based on hybrid digital and analog array architectures and the usage of radio frequency (RF) signal processing via phase shifters have emerged as potential solutions to improve energy efficiency and deliver performances close to digital arrays. In this paper, we provide an overview of the state-of-the-art mmW massive antenna array designs and comparison among three architectures, namely digital array, sub-array, and fully-connected hybrid array. The comparison of performance, power, and area for these three architectures is performed for three representative 5G use cases, which cover a range of pre-beamforming SNR and multiplexing regimes. This is the first study to comprehensively model and analyze all design aspects and criteria including: 1) optimal linear precoder, 2) impact of quantization error in DAC and phase shifters, 3) RF signal distribution network, 4) power and area estimation based on state-of-the-art mmW circuits including baseband precoding, digital signal distribution, DACs, oscillators and mixers, phase shifters, RF signal distribution, and power amplifiers. The results show that the digital array is the most power and area efficient compared against optimal design for each architecture. Our analysis shows digital array benefits greatly from multi-user multiplexing. The analysis also reveals that sub-array is limited by reduced beamforming gain due to array partitioning, and system bottleneck of the fully-connected hybrid architecture is the excessively power hungry RF signal distribution network.

description: Concrete is made up of three main ingredients which are cement, aggregates, and water.
 However, there were also other materials put into the concrete mix which is known as additive
 to increase the strength of the concrete. Concrete has high compressive strength, corrosion and
 weathering effect are minimal. However, concrete has low tensile strength and easily can be
 crack due to its characteristics which is brittle. Synthetic fibers were used to one of the effective
 additives to improve the tensile strength of concrete. But now the construction industry searches
 environmental friendly and economical construction material which is natural fiber.
 For this specific research, Teff straw fibers were used as a fiber-reinforced concrete material.
 The experimental investigation was done on C-25 concrete having a target mean strength of
 38.13MPa with a water-cement ratio of 0.59 and within a 30-60mm slump range. Compressive
 strength, Flexural strength, and Split tensile strength for 0%, 0.10%, 0.20% and 0.30% additions
 of teff straw fiber by weight of concrete were tested and compared with plain concrete.
 The standard 150mm cube compressive strength of Teff Fiber Reinforced Concrete with 0.10%
 addition of teff straw fiber by weight of concrete has shown a decrement of 3.95% . With 0.20%
 teff fiber has also shown a compressive strength decrement of 8.79% and with 0.30% teff fiber
 has shown a compressive strength reduction of 26.23% compared to plain concrete.
 Teff Fiber Reinforced Concrete with 0.10% addition of teff fiber by weight of concrete has
 shown tensile strength increment by 6.2% compared to plain concrete. With 0.20% teff fiber has
 also shown tensile strength increment of 11.28% which is a significant improvement and with
 0.30% teff fiber has shown a strong reduction of 16.6% compared to plain concrete.
 Mean Flexural strength of Teff Fiber Reinforced Concrete with 0.10% addition of teff fiber by
 weight of concrete has shown an increment of 2.55%. With 0.20% teff fiber addition has also
 shown a bending strength increment of 4.52% and with 0.30% of teff, fiber addition has shown
 a bending strength increment of 6.06% compared to plain concrete.
 Slump results for mixes 0.1% and 0.2% addition of teff fiber by weight of concrete are reduced
 by 45.45% and 54.55% for 0.30%,and finally for fresh concrete densities a slight reduction by
 1.95%, 2.12%, and 2.76% has shown respectively.
 Therefore 0.20% teff straw fiber addition is an optimum proportion for this specific research
 which results 11.28% by 28th day with significant increment for mean split tensile strength
 compared to plain concrete

description: The 256 dimensional M2-brane multiplet contains solitons of many different intrinsic spins. Using the broken supersymmetry transformations of the M2-brane, we find supergravity solutions which explicitly display these spins. This amounts to quantizing the fermionic zero modes and computing the back reaction on the metric and gauge potential. These spacetime fields are therefore operator valued and acquire a conventional classical meaning only after taking expectations in given BPS states. Our spinning spacetimes are not of the standard Kerr form -- there is a non-vanishing gravitino. Nevertheless, the solutions have angular momentum and magnetic dipole moments with a g-factor of 2. We use probe techniques to study scattering of spinning BPS M2-branes. The static interactions cancel between like-sign branes at leading order, but there are static spin-spin forces between branes and anti-branes. The general probe-background Lagrangian contains gravitational spin-spin and magnetic dipole-dipole forces, as well as gravitino exchanges which allow branes to change fermion number.

Machine-learning error models for approximate solutions to parameterized systems of nonlinear equations

Year: 2018
Subjects: subject: Numerical Analysis (math.NA)

description: This work proposes a machine-learning framework for constructing statistical models of errors incurred by approximate solutions to parameterized systems of nonlinear equations. These approximate solutions may arise from early termination of an iterative method, a lower-fidelity model, or a projection-based reduced-order model, for example. The proposed statistical model comprises the sum of a deterministic regression-function model and a stochastic noise model. The method constructs the regression-function model by applying regression techniques from machine learning (e.g., support vector regression, artificial neural networks) to map features (i.e., error indicators such as sampled elements of the residual) to a prediction of the approximate-solution error. The method constructs the noise model as a mean-zero Gaussian random variable whose variance is computed as the sample variance of the approximate-solution error on a test set; this variance can be interpreted as the epistemic uncertainty introduced by the approximate solution. This work considers a wide range of feature-engineering methods, data-set-construction techniques, and regression techniques that aim to ensure that (1) the features are cheaply computable, (2) the noise model exhibits low variance (i.e., low epistemic uncertainty introduced), and (3) the regression model generalizes to independent test data. Numerical experiments performed on several computational-mechanics problems and types of approximate solutions demonstrate the ability of the method to generate statistical models of the error that satisfy these criteria and significantly outperform more commonly adopted approaches for error modeling.

description: X-ray selected surveys of clusters of galaxies can distinguish between hierarchical models of the growth of structure in the Universe. Here we present the first results from an X-ray selected, flux and surface brightness limited deep survey for high redshift clusters and groups of galaxies based on ROSAT PSPC pointed data. The log(N)-log(S) relation of all clusters in this survey is consistent with that from most previous surveys but occupies a flux range not previously covered. At high redshifts (z>0.3) the cluster luminosities are in the range 4e43 to 2e44 erg/s, the luminosities of poor clusters. The number of high redshift, low luminosity clusters is consistent with no evolution of the X-ray luminosity function between redshifts of z=0.4 and z=0, and places a limit of a factor of <1.7 (at 90% confidence) on the amplitude of any pure negative density evolution of clusters of these luminosities, in contrast with the factor of approx 3 (corresponding to number density evolution proportional to (1+z)^{-2.5}) found in the EMSS survey at similar redshifts but higher luminosities. Taken together, these results support hierarchical models in which there is mild negative evolution of the most luminous clusters at high redshift but little or no evolution of the less luminous but more common, optically poor clusters. Models involving preheating of the X-ray gas at an early epoch fit the observations, at least for Omega_0=1.

description: We report on the first evidence for a non-zero rapidity-odd directed flow ($v_{1}$) for $D^{0}$ and $\overline{D^{0}}$ mesons in 10-80\% centrality Au+Au collisions at $\sqrt{s_{\rm NN}}$ = 200~GeV measured with the STAR detector at RHIC. The slope of the $v_1$ rapidity dependence ($dv_{1}/dy$) averaged over $D^{0}$ and $\overline{D^{0}}$ mesons is -0.081 $\pm$ 0.021 $\pm$ 0.017, while that of charged kaons is -0.0030 $\pm$ 0.0001 $\pm$ 0.0002, suggesting significantly larger slope for the $D^{0}$ mesons. Models indicate that the large $dv_{1}/dy$ of $D^{0}$ mesons is sensitive to the initially tilted source. We also present a new measurement of the $D^{0}$ meson elliptic flow ($v_2$) as a function of transverse momentum ($p_{T}$) in Au+Au collisions at $\sqrt{s_{\rm NN}}$ = 200~GeV with an improved precision with respect to the previously published results.The $D^{0}$ $v_{2}$ results are compared to those of light-flavor hadrons to test the number-of-constituent-quark (NCQ) scaling. Both the $v_{1}$ and $v_{2}$ results are compared to recent hydrodynamic and transport model calculations.

Chiral Phase Transition within Effective Models with Constituent Quarks

description: We investigate the chiral phase transition at nonzero temperature $T$ and baryon-chemical potential $μ_B$ within the framework of the linear sigma model and the Nambu-Jona-Lasinio model. For small bare quark masses we find in both models a smooth crossover transition for nonzero $T$ and $μ_B=0$ and a first order transition for T=0 and nonzero $μ_B$. We calculate explicitly the first order phase transition line and spinodal lines in the $(T,μ_B)$ plane. As expected they all end in a critical point. We find that, in the linear sigma model, the sigma mass goes to zero at the critical point. This is in contrast to the NJL model, where the sigma mass, as defined in the random phase approximation, does not vanish. We also compute the adiabatic lines in the $(T,μ_B)$ plane. Within the models studied here, the critical point does not serve as a ``focusing'' point in the adiabatic expansion.

description: We analyze the 2011 HST/COS spectrum of the Seyfert 1 galaxy NGC 3516, which demonstrates clear changes in one of the intrinsic absorption troughs (component 5), slight evidence of change in a second trough (component 6), and the appearance of a new absorption trough (component 9). We interpret both the changes and the appearance of the new trough as bulk motion across the line of sight. The implied lower limit on the transverse velocity of component 5 is 360 km/s, compared to the earlier 2001 HST/STIS spectrum, while the lower limits for components 6 and 9 are 920 km/s, based on 2009 FUSE data. Component 5 also exhibits a shift in velocity centroid. This is only the second known case of this behavior in a Seyfert galaxy. Due to the high quality of the HST/COS spectrum, we identify a previously undetected trough due to an excited state of Si II for component 1. In combination with the resonance trough of Si II and photoionization modeling, we directly determine the distance of the component 1 outflow to be 67.2 pc.

title: An approach for developing a fuel moisture content dataset for Austrian wildfire danger assessment
Creators: name: Plakolm, Christian Johannes
Publisher: name: TU Wien
Year: 2024
Subjects: subject: remote sensing
subject: wildfire
subject: vegetation moisture content

description: Fuel moisture content (FMC) of live vegetation is an important factor for wildfire ignition and propagation. Therefore, for wildfire danger assessment, it is inevitable to consider this parameter in models regarding the prediction of the ignition probability and spreading behaviour of wildfires. A current prototype of an integrated forest fire danger assessment system in Austria is introducing FMC as a functional derivative of meteorological conditions,which was calibrated for Canadian pine trees. To improve wildfire danger assessment in Austria, an updated FMC dataset that considers the local environmental and vegetational conditions is required. Observations from optical remote sensing instruments are sensitive to FMC in the infrared domain and thus, offering the possibility to estimate this quantity on a broader scale.An established global dataset for FMC is derived from the Moderate-Resolution Imaging Spectroradiometer (MODIS), which delivers temporally frequent reflectance data with a spatial resolution of 500 m. Modelling FMC with this pixel size might be too coarse when considering narrow valleys or mountain peaks. In this study, satellite observations from theSentinel-2 mission were used to calculate a new FMC dataset for the area of Styria with a high spatial resolution of 20 m. The aim was to develop a workflow that should further allow the FMC estimation for the entire Austrian country, which can support the domestic wildfire danger assessment. This was done by applying a pretrained machine learning model to Styrian Sentinel-2 data. This model was trained on Australian Sentinel-2 observations that were related to the MODIS derived FMC values. The validation of this approach with MODIS FMC data of Styria led to rather low correlations (ρ between 0 and 0.16) between the two datasets.A main reason for the low correlation results was identified as the relevant climatic and vegetational differences between Australia and the study area of Styria. Another reason was the different origin of the data. While the Sentinel-2 reflectances of Australia were subjected to a preprocessing algorithm, the Styrian data was originally taken from the Google Earth Engine tool. To develop a valid FMC dataset for Austria based on optical remote sensing data and machine learning algorithms, the training of a new model is recommended for further research work. The inclusion of a data layer that contains locally optimized FMC estimations with high spatial resolution remains a desirable goal for the Austrian wildfire danger assessment.

Strings and Discrete Fluxes of QCD

Year: 1999
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We study discrete fluxes in four dimensional SU(N) gauge theories with a mass gap by using brane compactifications which give ${\cal{N}} = 1$ or ${\cal{N}} = 0$ supersymmetry. We show that when such theories are compactified further on a torus, the t'Hooft magnetic flux $m$ is related to the NS two-form modulus $B$ by $B = 2π{m\over N}$. These values of $B$ label degenerate brane vacua, giving a simple demonstration of magnetic screening. Furthermore, for these values of $B$ one has a conventional gauge theory on a commutative torus, without having to perform any T-dualities. Because of the mass gap, a generic $B$ does not give a four dimensional gauge theory on a non-commutative torus. The Kaluza-Klein modes which must be integrated out to give a four dimensional theory decouple only when $B=2π{m\over N}$. Finally we show that $2π{m\over N}$ behaves like a two form modulus of the QCD string. This confirms a previous conjecture based on properties of large $N$ QCD suggesting a T-duality invariance.

description: Two-dimensional hexagonal and oblique lattices were investigated theoretically with the aim of observing differences in the spin expectation values between chiral and achiral systems. The spinresolved band structures were derived from the energy eigenvalues and eigenfunctions of a Hamiltonian that includes the lattice potential and the spin-orbit interaction. The spin texture of the achiral hexagonal system was shown to have two non-zero components of the spin polarisation, whereas all three components were calculated to be non-zero for the chiral system. The longitudinal component, found to be zero in the achiral lattice, was observed to invert between the enantiomorphs of the chiral lattice. A heuristic model was introduced to discern the origin of this inverting spin polarisation by considering the dynamics of an electron in chiral and achiral lattices. This model was further used to demonstrate the change in magnitude of the spin polarisation as a function of the lattice parameters and an electric field perpendicular to the lattice.

An epidemiological crack percolation model with application to probabilities of failure for gas turbines
Creators: name: Harder, Mathis

description: The versatility of gas turbines makes them the key to the energy transition, as they are able to meet various requirements. They are ideal for dealing with peak loads and effectively supplement renewable energy sources at times of low production.However, due to the many start and stop processes in this area of application, the components are exposed to high mechanical and thermal loads. Accurate modelling of the probability of failure is essential for safe operation and optimization of maintenance intervals.Nickel-based superalloys, which are commonly used in turbine components, have complex grain structures that influence fatigue life. In this work, we use the grain structure to create a percolation model. The crack initiation times of a single grain are based on the random orientations of the crystal lattice. The influence of a cracked grain on the surrounding material is modeled with finite element simulations. These simulations are used to create an infection function for the percolation model.The resulting epidemiological crack percolation model is calibrated and tested with experimental LCF data. For the transfer to large components, the crack initiation process is modeled as a spatio-temporal point process on the surface. This results in a post-processor for FE simulations with local cumulative hazard rates.

description: Herein, we isolated five natural alkaloids, iso-corydine (iso-CORY), corydine (CORY), sanguinarine (SAN), chelerythrine (CHE) and magnoflorine (MAG), from traditional medicinal herb Dicranostigma leptopodum (Maxim.) Fedde (whole herb) and elucidated their structures. Then we synthesised G5. NHAc-PBA as targeting dendrimer platform to encapsulate the alkaloids into G5. NHAc-PBA-alkaloid complexes, which demonstrated alkaloid-dependent positive zeta potential and hydrodynamic particle size. G5. NHAc-PBA-alkaloid complexes demonstrated obvious breast cancer MCF-7 cell targeting effect. Among the G5. NHAc-PBA-alkaloid complexes, G5.NHAc-PBA-CHE (IC50=13.66 μM) demonstrated the highest MCF-7 cell inhibition capability and G5.NHAc-PBA-MAG (IC50=24.63 μM) had equivalent inhibitory effects on cell proliferation that comparable to the level of free MAG (IC50=23.74 μM), which made them the potential breast cancer targeting formulation for chemotherapeutic application. This work successfully demonstrated a pharmaceutical research model of ‘natural bioactive product isolation-drug formulation preparation-breast cancer cell targeting inhibition’.

description: Sediment samples were collected from a trench across an active normal fault in the Fort Sage Mountains in northeast California with the purpose of gaining insight into earthquake activity. These sediment samples were examined to recover organic material suitable for AMS radiocarbon dating. No macroscopic charcoal or other organic fragments were noted in these samples; therefore, they were processed to recover microscopic charcoal fragments (microcharcoal) for dating. Two of the samples yielded sufficient microcharcoal to obtain AMS radiocarbon dates.
Angular size and emission time scales of relativistic fireballs

description: The detection of delayed X-ray, optical and radio emission, ``afterglow,'' associated with gamma-ray bursts (GRBs) is consistent with models, where the bursts are produced by relativistic expanding blast waves, driven by expanding fireballs at cosmological distances. In particular, the time scales over which radiation is observed at different wave bands agree with model predictions. It had recently been claimed that the commonly used relation between observation time t and blast wave radius r, t=r/2γ^{2}c where γ(r) is the fluid Lorentz factor, should be replaced with t=r/16γ^{2}c due to blast wave deceleration. Applying the suggested deceleration modification would make it difficult to reconcile observed time scales with model predictions. It would also imply an apparent source size which is too large to allow attributing observed radio variability to diffractive scintillation. We present a detailed analysis of the implications of the relativistic hydrodynamics of expanding blast waves to the observed afterglow. We find that modifications due to shock deceleration are small, therefore allowing for both the observed afterglow time scales and for diffractive scintillation. We show that at time t the fireball appears on the sky as a narrow ring of radius h=r/γand width 0.1h, where r and t are related by t=r/2γ^{2}c.

Electroweak double logarithms in inclusive observables for a generic initial state

description: High energy observables are characterized by large electroweak radiative corrections of infrared origin; double logarithms are present even for inclusive cross sections, thus violating the Bloch Nordsieck theorem. This effect, related to the initial states carrying nonabelian isospin charges, is here investigated for {\sl any} inclusive cross section in the SU(2)$\otimes$U(1) symmetric limit, that is appropriate for energies much higher than the weak scale. We develop a general formalism allowing to calculate the all order double log resummed cross sections once the hard (tree level) ones are known. The relevant cases of fermion-fermion, fermion-boson and boson-boson scattering are discussed.

Chiral Perturbation Theory for Vector Mesons

description: The interactions of $ρ$, $K^*$, $ϕ$ and $ω$ vector-mesons with low-momentum $π$, $K$ and $η$ pseudoscalar mesons are constrained by chiral symmetry. We derive a heavy vector-meson chiral Lagrangian in which the vector mesons are treated as heavy static matter fields. The unknown couplings of the chiral Lagrangian are further related using the $1/N_c$ expansion. Chiral perturbation theory is applied to the vector-meson mass matrix. At one-loop there are large corrections to the individual vector meson masses, but the singlet-octet mixing angle remains almost unchanged. The parity-violating $s$-wave $\phiC \rightarrow ρπ$ weak decay amplitude is derived in the combined chiral and large $N_c$ limits. Rare $ϕ$ decays provide a sensitive test of non-leptonic neutral current structure.

description: We report the first results of a color-magnitude diagram survey of 25 candidate old LMC clusters. For almost all of the sample, it was possible to reach the turnoff region, and in many clusters we have several magnitudes of the main sequence. Age estimates based on the magnitude difference $δT_1$ between the giant branch clump and the turnoff revealed that no new old clusters were found. The candidates turned out to be of intermediate age (1-3 Gyr) We show that the apparently old ages as inferred from integrated UBV colors can be explained by a combination of stochastic effects produced by bright stars and by photometric errors for faint clusters lying in crowded fields. The relatively metal poor candidates from the CaII triplet spectroscopy also turned out to be of intermediate age. This, combined with the fact that they lie far out in the disk, yields interesting constraints regarding the formation and evolution of the LMC disk. We also study the age distribution of intermediate age and old clusters This homogeneous set of accurate relative ages allows us to make an improved study of the history of cluster formation/destruction for ages $>1$Gyr. We confirm previous indications that there was apparently no cluster formation in the LMC during the period from 3-8 Gyr ago, and that there was a pronounced epoch of cluster formation beginning 3 Gyrs ago that peaked at about 1.5 Gyrs ago. Our results suggest that there are few, if any, genuine old clusters in the LMC left to be found.
