description: We present new long-baseline spectro-interferometric observations of the HerbigAe star HD163296 obtained in the H and K bands with the AMBER instrument at VLTI. The observations cover a range of spatial resolutions between 3 and 12 milli-arcseconds, with a spectral resolution of ~30. With a total of 1481 visibilities and 432 closure phases, they result in the best (u,v) coverage achieved on a young star so far. The circumstellar material is resolved at the sub-AU spatial scale and closure phase measurements indicate a small but significant deviation from point-symmetry. We discuss the results assuming that the near-infrared excess in HD163296 is dominated by the emission of a circumstellar disk. A successful fit to the spectral energy distribution, near-infrared visibilities and closure phases is found with a model where a dominant contribution to the H and K band emissions arises from an optically thin, smooth and point-symmetric region extending from about 0.1 to 0.45 AU. At the latter distance from the star, silicates condense, the disk becomes optically thick and develops a puffed-up rim, whose skewed emission can account for the non-zero closure phases. We discuss the nature of the inner disk emission and tentatively rule out dense molecular gas as well as optically thin atomic or ionized gas as its possible origin. We propose instead that the inner emission traces the presence of very refractory grains in a partially cleared region, extending at least to 0.5 AU. If so, we may be observing the disk of HD163296 just before it reaches the transition disk phase. However, we note that the nature of the refractory grains or even the possibility for any grain to survive at the very high temperatures we require (~2100-2300 K at 0.1 AU from the star) is unclear and should be investigated further.

description: Samaaegne kahepoolne spontaanne pneumotooraks on harva esinev haigus, mis võib aga olla eluohtlik ning sellest tulenevalt vajab kiiret diagnostikat ja ravi. Artiklis on käsitletud samaaegse kahepoolse primaarse spontaanse pneumotooraksi haigusjuhtu 24aastasel noormehel, kes pöördus perearsti vastuvõtule hingamispuudulikkuse ning valuga mõlemal pool rindkeres. Diagnoosini jõuti alles haiglas pärast rindkere röntgeniülesvõtte tegemist. Vahetult uuringu järel tekkis haigel kliiniline surm. Olukorra lahendas trahhea kohene intubatsioon, kahepoolse pleuradrenaaži rajamine ja juhitava hingamise rakendamine. Edasiseks raviks suunati patsient TÜ Kliinikumi, kus tehti mõlemapoolne videotorakoskoopiline kopsuresektsioon koos parietaalse pleurektoomiaga, et vältida haiguse retsidiveerumist. Operatsioon ja postoperatiivne periood kulgesid tüsistusteta. 8 kuud pärast kirurgilist ravi on patsient kaebusteta ning pneumotooraks ei ole kordunud.

description: Molecular dynamics simulations and instantaneous normal mode (INM) analysis of a fluid with core-softened pair interactions and water-like liquid-state anomalies are performed to obtain an understanding of the relationship between thermodynamics, transport properties and the poten- tial energy landscape. Rosenfeld-scaling of diffusivities with the thermodynamic excess and pair correlation entropy is demonstrated for this model. The INM spectra are shown to carry infor- mation about the dynamical consequences of the interplay between length scales characteristic of anomalous fluids, such as bimodality of the real and imaginary branches of the frequency distribu- tion. The INM spectral information is used to partition the liquid entropy into two contributions associated with the real and imaginary frequency modes; only the entropy contribution from the imaginary branch captures the non-monotonic behaviour of the excess entropy and diffusivity in the anomalous regime of the fluid.

description: We show that string duality relates M-theory on a local Calabi-Yau fourfold singularity X4 to type IIA string theory on a Calabi-Yau threefold X3 fibered over a real line, with RR 2-form fluxes turned on. The RR flux encodes how the M-theory circle is fibered over the IIA geometry. The theories on N D2 branes probing X3 are the well-known quiver theories with N=2 supersymmetry in three dimensions. We show that turning on fluxes, and fibering the X3 over a direction transverse to the branes, corresponds to turning on N=2 Chern-Simons couplings. String duality implies that, in the strong coupling limit, the N D2 branes on X3 in this background become N M2 branes on X4. This provides a string theory derivation for the recently conjectured description of the M2 brane theories on Calabi-Yau fourfolds in terms of N=2 quiver Chern-Simons theories. We also provide a new N=2 Chern-Simons theory dual to AdS_4 x Q^{1,1,1}. Type IIA/M-theory duality also relates IIA string theory on X3 with only the RR fluxes turned on, to M-theory on a G2 holonomy manifold. We show that this implies that the N M2 branes probing the G2 manifold are described by the quiver Chern-Simons theory originating from the D2 branes probing X3, except that now Chern-Simons terms preserve only N=1 supersymmetry in three dimensions.

description: Dissipative Kerr solitons formed in high-$Q$ optical microresonators provide a route to miniaturized optical frequency combs that can revolutionize precision measurements, spectroscopy, sensing, and communication. In the last decade, a myriad of integrated material platforms have been extensively studied and developed to create photonic-chip-based soliton combs. However, the photo-thermal effect in integrated optical microresonators has been a major issue preventing simple and reliable soliton generation. Several sophisticated techniques to circumvent the photo-thermal effect have been developed. In addition, instead of the single-soliton state, emerging applications in microwave photonics and frequency metrology prefer multi-soliton states. Here we demonstrate an approach to manage the photo-thermal effect and facilitate soliton generation. The approach is based on a single phase-modulated pump, where the generated blue-detuned sideband synergizes with the carrier and thermally stabilizes the microresonator. We apply this technique and demonstrate deterministic soliton generation of 19.97 GHz repetition rate in an integrated silicon nitride microresonator. Furthermore, we develop a program to automatically address to target $N-$soliton state, in addition to the single-soliton state, with near 100% success rate and as short as 10 s time consumption. Our method is valuable for soliton generation in essentially any platforms even with strong photo-thermal effect, and can promote wider applications of soliton frequency comb systems for microwave photonics, telecommunication and frequency metrology.

description: A cosmological scenario in which the onset of neutrino free streaming in the early Universe is delayed until close to the epoch of matter-radiation equality has been shown to provide a good fit to some cosmic microwave background (CMB) data, while being somewhat disfavored by Planck CMB polarization data. To clarify this situation, we investigate in this paper CMB-independent constraints on this scenario from the Full Shape of the galaxy power spectrum. Although this scenario predicts significant changes to the linear matter power spectrum, we find that it can provide a good fit to the galaxy power spectrum data. Interestingly, we show that the data display a modest preference for a delayed onset of neutrino free streaming over the standard model of cosmology, which is driven by the galaxy power spectrum data on mildly non-linear scales. This conclusion is supported by both profile likelihood and Bayesian exploration analyses, showing robustness of the results. Compared to the standard cosmological paradigm, this scenario predicts a significant suppression of structure on subgalactic scales. While our analysis relies on the simplest cosmological representation of neutrino self-interactions, we argue that this persistent - and somehow consistent - picture in which neutrino free streaming is delayed motivates the exploration of particle models capable of reconciling all CMB, large-scale structure, and laboratory data.

description: We address two-dimensional waveguide arrays where light tunneling into neighboring waveguides may be effectively suppressed by out-of-phase harmonic modulation of the refractive index in neighboring waveguides at suitable frequencies. Genuine two-dimensional features, such as anisotropic diffraction engineering, diffraction-free propagation along selected directions in the transverse plane and tunneling inhibition for multi-channel vortices, are shown to occur.

title: Development and Validation of a Waiver Test For the Math Content Courses Required of Elementary Education Majors at Utah State University
Creators: name: Tolman, Marvin Nelson
Publisher: name: Utah State University
Year: 1975

description: Purpose and Procedures
The purpose of this paper was to construct and validate an instrument which could effectively identify students enrolled in the elementary teacher training program at Utah State University whose mathematical competency equals or exceeds the standard for completion of the required math content courses prior to taking those courses. It was the hope of the writer that such students would be allowed to waive those courses and substitute courses representing areas of greater need for the individual student.
Care was taken in the construction and validation of the instrument to assure content validity with college-level texts designed for such courses and elementary texts which the teacher is expected to use in the teaching situation.
Preliminary forms of the instrument constructed in the study were administered to pilot groups. An item analysis was performed to determine the level of difficulty and discriminating power of individual test items as well as the ability of the distractors to distract. The final form consisted of 58 multiple-choice test items.
Results
Using Kuder-Richardson reliability formula number 20, the reliability coefficient of the instrument was .87, which indicates a high level of reliability for a screening test. The variance was 82.72, resulting in a standard deviation of 9.10.
Correlating the test results, when used as a pretest in the above-mentioned courses, with final grades in the course resulted in a correlation coefficient which was significant at the .01 level of significance, indicating high predictive validity of the instrument with actual success in the course.

description: Agenda: Activities and status so far: Online seminar series Metadata/Data Annotation - Paula DMP for engineering disciplines - Daniela PIDs for Instruments within engineering - Nikola Presentation on “Provenance on engineering data” (Gretchen Greene - NIST) The RDA has long been a proponent of the value in capturing provenance for research data. Why is this important for Engineering? Engineering thrives most often when there is a system level approach for conducting research with interconnected processes and data sources of varying nature. In this discussion we share key concepts, known/existing provenance models, and explore ideas where provenance information can support what’s missing in navigating the data space in engineering research (and yes this includes software!) Presentation on “Research software for engineers” (Sibylle Hermann - University of Stuttgart and Santosh Ilamparuthi - Delft University of Technology) Research results in engineering are often software or are based on software. However, most engineers are not trained in software development. Software engineering principles can not be fully adopted for research software, because software development is not the actual goal itself, it is the means to an end. In engineering sciences in particular, obstacles for sharing code are that code is developed within industrial cooperation with confidentiality agreements in place and the widespread use of commercial software such as Matlab. The following questions are intended to be addressed: - Which software development skills are needed by engineers? - How can research software be better documented and shared in the engineering context? - What basic conditions do we need to achieve FAIR research software in engineering? Group work like a world cafe breakout room on the topics “engineering data provenance” and “research software in engineering” after half the time the participants swap breakout rooms so that everyone has the opportunity to discuss both topics 3-minute-pitches from the breakout rooms Closure, discussion on next steps

description: Here, we reported a haplotype-resolved and telomere-to-telomere genome assembly of M. acuminata using PacBio HiFi reads, Nanopore ultra-long reads and high-covered Hi-C data. This assembly represented a significantly high-quality reference assessed by contiguity (contig N50: 16.53Mb and 18.58Mb; LAI: 20.18 and 19.48), completeness (BUSCOs: 98.57% and 98.57%), and correctness (QV: 45.97 and 46.12). All centromeres and 36 of 44 telomeres had been captured. The mapping rates of HiFi and Illumina reads both exceeded 99.80%. In total, 40,889 and 38,269 protein-coding genes were annotated in the two haploid assemblies, respectively, of which 9.56% and 3.37% were newly annotated compared with previous databases. Gene BUSCOs reached up to 89.41% and 90.27%, respectively. Through comparing our assembly and the previously published genome of M. acuminata, we identified two large translocation regions with length of 3 Mb and 10 Mb, which were further confirmed by Hi-C heatmap and targeted-PCR gel electrophoresis. This haplotype-resolved and telomere-to-telomere reference genome of M. acuminata provides an excellent resource for further understanding the mechanisms of subgenome evolution, domestication history, and genetic breeding of banana.

description: We present high-resolution spectroscopic measurements of the abundances of titanium (Ti), yttrium (Y) and lanthanum (La) for M giant candidates of the Sagittarius (Sgr) dwarf spheroidal (dSph) + tidal tail system pre-selected on the basis of position and radial velocity. The majority of these stars show peculiar abundance patterns compared to those of nominal Milky Way (MW) stars. The overall [Ti/Fe], [Y/Fe], [La/Fe] and [La/Y] patterns with [Fe/H] of the Sgr stream plus Sgr core do resemble those seen in the Large Magellanic Cloud (LMC) and other dSphs, only shifted [Fe/H] by ~+0.4 from the LMC and by ~+1 dex from the other dSphs; these relative shifts reflect the faster and/or more efficient chemical evolution of Sgr compared to the other satellites, and show that Sgr has had an enrichment history more like the LMC than the other dSphs. By tracking the evolution of the abundance patterns along the Sgr stream we can follow the time variation of the chemical make-up of dSph stars donated to the MW halo by Sgr. This evolution demonstrates that while the bulk of the stars currently in the Sgr dSph are quite unlike those of the MW halo, an increasing number of stars farther along the Sgr stream have abundances like MW halo stars, a trend that shows clearly how the MW halo could have been contributed by present day satellite galaxies even if the present chemistry of those satellites is now different from typical halo field stars. Finally, we analyze the chemical abundances of a moving group of M giants among the Sgr leading arm stars at the North Galactic Cap, but having radial velocities unlike the infalling Sgr leading arm debris there. Through use of "chemical fingerprinting", we conclude that these northern hemisphere M giants also are Sgr stars, likely trailing arm debris overlapping the leading arm in the north.

description: Transition out of a topological phase is typically characterized by discontinuous changes in topological invariants along with bulk gap closings. However, as a clean system is geometrically punctured, it is natural to ask the fate of an underlying topological phase. To understand this physics we introduce and study both short and long-ranged toy models where a one dimensional topological phase is subjected to bond percolation protocols. We find that non-trivial boundary phenomena follow competing energy scales even while global topological response is governed via geometrical properties of the percolated lattice. Using numerical, analytical and appropriate mean-field studies we uncover the rich phenomenology and the various cross-over regimes of these systems. In particular, we discuss emergence of "fractured topological region" where an overall trivial system contains macroscopic number of topological clusters. Our study shows the interesting physics that can arise from an interplay of geometrical disorder within a topological phase.

Publisher: name: University of British Columbia
Year: 2011

description: The oxidation of artificial cuprous sulphide electrodes (Cu/S ratio = 1.93) was studied in acidified copper sulphate solutions in the temperature range 20 to 35° C. Rest potential measurements gave V° = 0.490 volts for the electrode or half cell potential. This is within the limits of accuracy of V° for: Cu₂S —CuS + Cu⁺⁺ + 2e V° = 0.535 + 0.13 volts The discrepancy was thought to be related to the large Cu deficien in the sulphide. In solutions with pH>4, the rest potential measurements were consistent with the following reaction: Cu₂S + 2H₂0 —CuS + Cu(OH)₂ + 2H⁺ + 2e Polarization measurements at low overpotential gave values for the following kinetic parameters: β, the symmetry factor = 1/2 λ, the number of electrons involved in each act of the rate determining step = 2 i₀, the exchange current ≈ 2 x 10-⁵ A/cm² ΔH₀*, the standard heat of activation = 26.5 kcal/mole CuS was tentatively identified as one of the reaction products. A reaction mechanism was discussed.

title: Noise Pollution as a Potential Safety and Health Hazard Within Selected Utah Industrial Education Laboratory Facilities
Creators: name: Hicks, Carol E.
Publisher: name: Utah State University
Year: 1973

description: The major purpose of this study was to investigate the existing noise conditions within industrial education woodworking and metalworking laboratories to determine whether these noise conditions were a problem as seen by the instructors and if in fact these noise conditions exceeded the standards set by the Occupational Safety and Health Act (OSHA). The study was conducted in three phases: (1) the assessment of the opinions of professional industrial educators towards noise as a pollutant; (2) an electronic instrument measurement of the actual noise exposure conditions that existed in a sampling of laboratories; and (3) the comparison between the opinions of the professional educators and the actual laboratory noise conditions.
The study incorporated the responses from every identifiable high school woods and metals instructor throughout Utah. Comparisons between groups were made concerning the opinions of the professional educators.
towards noise as a pollutant, their knowledge about OSHA, and their identification of the noisiest pieces of equipment. The second phase of the study entailed the electronic instrument measurement of the actual environmental noise levels within 30 randomly selected laboratories. The use of a sound level dosimeter and a hand held sound level meter were employed.
The data obtained from the study disclosed that the two groups were not in agreement on their knowledge about OSHA. The electronic instrument measurements revealed that 8 of the 18 woodworking instructors and 5 of the 12 metals instructors visited were subjected to noise exposures that were in violation to OSHA. The loudest pieces of equipment were the surface planer, radial arm saw, table saw, foundry furnace, pedestal grinder and portable disc grinder.
The third phase of the study used a statistical analysis to compare the opinions of the instructors to the actual measured noise conditions. The chi-square test for significance at the . 05 level of confidence was used to reject the null hypothesis.
The major conclusions reached as a result of the analysis of data include: (1) a potential safety and health hazard exists from noise pollution within the industrial education facilities; (2) many members of the profession are not fully informed about OSHA; (3) most labs are in compliance to OSHA noise standards, however, many do exceed the maximum a llowable limits; (4) under stringent OSHA compliance, certain curriculum alterations would have to be initiated; (5) there is no apparent connection between those laboratoryies which were in volation to OSIIA noise standards and the composition of size and construction materials; (6) the opinions of the teachers from the field do not necessarily reflect the actual measured conditions of the environmental noise exposures; and (7) the din of noise produced around machinery must not be considered a problem relevant only to industry.

description: Ages of 213 deer killed during the 1972 hunting season were determined by: (1) eruption-replacement and wear criteria in the field: (2) employing the tooth eruption-replacement and wear criteria under optimum laboratory conditions; and by {3) cementum-annulation counts . Incisors collected for cementum-annulation counts were decalcified in 5 percent nitric acid, sections 16-18 microns were cut on a cryostat and stained in hematoxylin for 18 ± 2 minutes . Age determinations by cementumannulation counts showed 87 percent agreement with the results obtained by eruption-replacement and wear criteria in the laboratory.
Survival rates were estimated from the age distribution of 740 teeth aged by cementum-annulation counts . The average adult doe survival rate was 0.55 . Other population parameters were also determined. All five deer herds showed apparent negative rates of population change, averaging -0.14. The adult female survival rate appeared to be the major source of variation between units in rate of population change. The correlation between hunting pressure and the rate of population change was statistically significant .

description: CNN architectures are generally heavy on memory and computational requirements which makes them infeasible for embedded systems with limited hardware resources. We propose dual convolutional kernels (DualConv) for constructing lightweight deep neural networks. DualConv combines 3$\times$3 and 1$\times$1 convolutional kernels to process the same input feature map channels simultaneously and exploits the group convolution technique to efficiently arrange convolutional filters. DualConv can be employed in any CNN model such as VGG-16 and ResNet-50 for image classification, YOLO and R-CNN for object detection, or FCN for semantic segmentation. In this paper, we extensively test DualConv for classification since these network architectures form the backbones for many other tasks. We also test DualConv for image detection on YOLO-V3. Experimental results show that, combined with our structural innovations, DualConv significantly reduces the computational cost and number of parameters of deep neural networks while surprisingly achieving slightly higher accuracy than the original models in some cases. We use DualConv to further reduce the number of parameters of the lightweight MobileNetV2 by 54% with only 0.68% drop in accuracy on CIFAR-100 dataset. When the number of parameters is not an issue, DualConv increases the accuracy of MobileNetV1 by 4.11% on the same dataset. Furthermore, DualConv significantly improves the YOLO-V3 object detection speed and improves its accuracy by 4.4% on PASCAL VOC dataset.

description: The future challenge of quantum communication are scalable quantum networks, which require coherent and reversible mapping of photonic qubits onto stationary atomic systems (quantum memories). A crucial requirement for realistic networks is the ability to efficiently store multiple qubits in one quantum memory. Here we demonstrate coherent and reversible mapping of 64 optical modes at the single photon level in the time domain onto one solid-state ensemble of rare-earth ions. Our light-matter interface is based on a high-bandwidth (100 MHz) atomic frequency comb, with a pre-determined storage time of 1 microseconds. We can then encode many qubits in short <10 ns temporal modes (time-bin qubits). We show the good coherence of the mapping by simultaneously storing and analyzing multiple time-bin qubits.

title: Effect of Diet Levels of Leucine, Isoleucine and Valine on Chick Growth Rate
Creators: name: Nakhata, Naiyana
Publisher: name: Utah State University
Year: 1975

description: Chick feeding tests were conducted to study the effects of dietary imbalances among the three branched chain amino acids on growth rate. All diets fed in these tests contained about 18% protein. The indispensable amino acids (IAA) were found in two of the diets fed in the proportions found by Dobson et al. (1964) to be well balanced. One of the diets had all IAA at 85% of these balanced levels while the other had them all at 125% of these levels. The tests involved reducing the isoleucine, leucine and valine levels in the high IAA diet to the low levels in all combinations.
Growth rates were similar with the diets containing all ten IAA at the low levels, all ten at the high levels, or seven at the high levels and isoleucine, leucine and valine at the low levels. Generally, when only one or two of these three were reduced to the low levels, growth rates were lower. Thus there appeared to be a three-way interaction among these amino acids with the reduction in weight gain being the result of an imbalance and not of a deficiency. The changes in growth rate noted when the leucine level was reduced indicated that the leucine level in Dobson's balanced diet was relatively high; the isoleucine level appeared to be relatively low. The interaction between leucine and valine appeared to be more significant than the other two two-way interactions.
The effect of dietary level of these amino acids on the branched chain amino acid transaminase (BAT) activity in the liver and kidneys was determined. The differences noted were inconsistent. There tended to be a slightly higher activity in chicks fed the high levels of these amino acids, but the differences certainly were not as great as the changes in arginase activity reported by others when imbalanced diets were fed.
Chicks fed the diet low in valine and high in the other nine IAA were selected for fast or slow growth on this diet. They were raised to maturity and produced eggs that were hatched for feeding tests with the diets containing different levels of the branched chain amino acids. Only a limited number of chicks from the two strains were hatched. Performance of the chicks was similar to that of their parents when fed the low valine diet.

description: We study the behavior of dynamical systems under time reparameterizations, which is important not only to characterize chaos in relativistic systems but also to probe the invariance of dynamical quantities. We first show that time transformations are locally equivalent to metric transformations, a result that leads to a transformation rule for all Lyapunov exponents on arbitrary Riemannian phase spaces. We then show that time transformations preserve the spectrum of generalized dimensions D_q except for the information dimension D_1, which, interestingly, transforms in a nontrivial way despite previous assertions of invariance. The discontinuous behavior at q=1 can be used to constrain and extend the formulation of the Kaplan-Yorke conjecture.
A Critical Analysis of Internal Reliability for Uncertainty Quantification of Dense Image Matching in Multi-view Stereo

description: Nowadays, photogrammetrically derived point clouds are widely used in many civilian applications due to their low cost and flexibility in acquisition. Typically, photogrammetric point clouds are assessed through reference data such as LiDAR point clouds. However, when reference data are not available, the assessment of photogrammetric point clouds may be challenging. Since these point clouds are algorithmically derived, their accuracies and precisions are highly varying with the camera networks, scene complexity, and dense image matching (DIM) algorithms, and there is no standard error metric to determine per-point errors. The theory of internal reliability of camera networks has been well studied through first-order error estimation of Bundle Adjustment (BA), which is used to understand the errors of 3D points assuming known measurement errors. However, the measurement errors of the DIM algorithms are intricate to an extent that every single point may have its error function determined by factors such as pixel intensity, texture entropy, and surface smoothness. Despite the complexity, there exist a few common metrics that may aid the process of estimating the posterior reliability of the derived points, especially in a multi-view stereo (MVS) setup when redundancies are present. In this paper, by using an aerial oblique photogrammetric block with LiDAR reference data, we analyze several internal matching metrics within a common MVS framework, including statistics in ray convergence, intersection angles, DIM energy, etc.

description: Introduced in 1998 to attempt a first unified view of the broad-band emission properties of blazars, the blazar sequence has been extensively used in the past 25 years to guide observations as well as physical interpretation of the overall emission from these galaxies. In this review, we describe the evolution of the sequence along with the tremendous advances in the observational field, in particular in the gamma-ray band. A new version of the sequence built on TeV-detected objects is also presented. Two extreme classes of objects (MeV and hard-TeV blazars) are included in the discussion, given their relevance for future observatories. Finally, the current physical understanding at the base of the sequence is presented along with the major criticisms to the blazar sequence.

description: The 3-body recombination rate at threshold for distinguishable atoms with large negative pair scattering lengths is calculated in the zero-range approximation. The only parameters in this limit are the 3 scattering lengths and the Efimov parameter, which can be complex valued. We provide semi-analytic expressions for the cases of 2 or 3 equal scattering lengths and we obtain numerical results for the general case of 3 different scattering lengths. Our general result is applied to the three lowest hyperfine states of Lithium-6 atoms. Comparisons with recent experiments provide indications of loss features associated with Efimov trimers near the 3-atom threshold.

Micromechanics-Informed Parametric Deep Material Network for Physics Behavior Prediction of Heterogeneous Materials with a Varying Morphology
Creators: name: Li, Tianyi
Publisher: name: arXiv
Year: 2023
Subjects: subject: Computational Engineering, Finance, and Science (cs.CE)

description: Deep Material Network (DMN) has recently emerged as a data-driven surrogate model for heterogeneous materials. Given a particular microstructural morphology, the effective linear and nonlinear behaviors can be successfully approximated by such physics-based neural-network like architecture. In this work, a novel micromechanics-informed parametric DMN (MIpDMN) architecture is proposed for multiscale materials with a varying microstructure characterized by several parameters. A single-layer feedforward neural network is used to account for the dependence of DMN fitting parameters on the microstructural ones. Micromechanical constraints are prescribed both on the architecture and the outputs of this new neural network. The proposed MIpDMN is also recast in a multiple physics setting, where physical properties other than the mechanical ones can also be predicted. In the numerical simulations conducted on three parameterized microstructures, MIpDMN demonstrates satisfying generalization capabilities when morphology varies. The effective behaviors of such parametric multiscale materials can thus be predicted and encoded by MIpDMN with high accuracy and efficiency.

description: We show that large-scale typicality of Markov sample paths implies that the likelihood ratio statistic satisfies a law of iterated logarithm uniformly to the same scale. As a consequence, the penalized likelihood Markov order estimator is strongly consistent for penalties growing as slowly as log log n when an upper bound is imposed on the order which may grow as rapidly as log n. Our method of proof, using techniques from empirical process theory, does not rely on the explicit expression for the maximum likelihood estimator in the Markov case and could therefore be applicable in other settings.
