Master-slave force-reflecting resolved motion control of hydraulic mobile machines
Creators: name: Zhu, Ming
Publisher: name: University of British Columbia
Year: 2009

description: Issues concerning the design and implementation of master-slave force-reflecting resolved motion control of hydraulic mobile machines are addressed in this thesis. Network concepts and linear system theory are used to design and analyze general force-reflecting teleoperator systems to achieve high performance while maintaining stability. A new control structure is proposed to achieve "transparency" for teleoperator systems under rate control. A novel approach to stability analysis of the stiffness feedback strategy proposed in previous work is provided which, under certain condition, guarantees global asymptotic stability of the teleoperator system. The system could be either under rate or position control and could be subject to time-delays, nonlinearities or active environments. The closed-form inverse kinematics solutions of an excavator and a feller-buncher, which are four and five degree-of-freedom manipulators respectively, are provided to achieve resolvedmotion of the manipulator's end-effector. Using the UBC magnetically levitated joystick, the master-slave force-reflecting resolved motion control has been successfully implemented on a CAT-215 excavator and a CAT-325 feller-buncher. Machine experiments demonstrate the effectiveness of this control strategy in improving productivity and safety of general hydraulic mobile machines.

description: We quantify the intrinsic width of the red giant branches of three massive globular clusters in M31 in a search for metallicity spreads within these objects. We present HST/ACS observations of three massive clusters in M31, G78, G213, and G280. A thorough description of the photometry extraction and calibration is presented. After derivation of the color-magnitude diagrams, we quantify the intrinsic width of the red giant branch of each cluster. This width translates into a metallicity dispersion that indicates a complex star formation history for this type of system. For G78, sigma_[Fe/H]}=0.86 \pm 0.37; for G213, 0.89 \pm 0.20; and for G280, 1.03 \pm 0.26. We find that the metallicity dispersion of the clusters does not scale with mean metallicity. We also find no trend with the cluster mass. We discuss some possible formation scenarios that would explain our results.

description: We present sensitive ALMA observations of TWA 3, a nearby, young ($\sim$10 Myr) hierarchical system composed of three pre-main sequence M3--M4.5 stars. For the first time, we detected ${}^{12}$CO and ${}^{13}$CO $J$=2-1 emission from the circumbinary protoplanetary disk around TWA 3A. We jointly fit the protoplanetary disk velocity field, stellar astrometric positions, and stellar radial velocities to infer the architecture of the system. The Aa and Ab stars ($0.29\pm0.01\,M_\odot$ and $0.24\pm0.01\,M_\odot$, respectively) comprising the tight ($P=35$ days) eccentric ($e=0.63\pm0.01$) spectroscopic binary are coplanar with their circumbinary disk (misalignment $< 6^{\circ}$ with 68% confidence), similar to other short-period binary systems. From models of the spectral energy distribution, we found the inner radius of the circumbinary disk ($r_\mathrm{inner} = 0.50 - 0.75$ au) to be consistent with theoretical predictions of dynamical truncation $r_\mathrm{cav}/a_\mathrm{inner} \approx 3$. The outer orbit of the tertiary star B ($0.40\pm0.28\,M_\odot$, $a\sim65 \pm 18$ au, $e=0.3\pm0.2$) is not as well constrained as the inner orbit, however, orbits coplanar with the A system are still preferred (misalignment $ < 20^{\circ}$). To better understand the influence of the B orbit on the TWA 3A circumbinary disk, we performed SPH simulations of the system and found that the outer edge of the gas disk ($r_\mathrm{outer}=8.5\pm0.2$ au) is most consistent with truncation from a coplanar, circular or moderately eccentric orbit, supporting the preference from the joint orbital fit.

description: We present an argument in which the scale ~ 0.1 eV associated with neutrino masses naturally appears in a a class of (very) large volume compactifications, being tied to a supersymmetry scale of 10^3 GeV and a string scale of 10^11 GeV. The masses are of Majorana type and there is no right-handed neutrino within the low-energy field theory. The suppression scale 10^14 GeV is independent of the masses of the heavy states that are integrated out. These kind of constructions appear naturally in Type IIB flux compactifications. However, the arguments that lead to this result rely only on a few geometrical features of the compactification manifold, and hence can be used independently of string theory.

description: We compactify the ten-dimensional spacetime in heterotic supergravity leaving four-dimensional Minkowski spacetime. We search for nonsupersymmetric, non-Ricci-flat solutions of the equations of motion with the quadratic curvature term. By assuming that the extradimensional spaces are products of 2-manifolds, three types of solutions are found. They are $S^2\times T^2 \times H^2/Γ$, $S^2\times H^2/Γ\times H^2/Γ$, and $S^2\times S^2 \times H^2/Γ$, where $H^2/Γ$ denotes a compact hyperbolic manifold. The metrics can be written explicitly, and they can be applied to phenomenology.

description: We investigate the effects of two electronic bands at the negative electronic compressibility (NEC) in a two-dimensional electron gas (2DEG). We use a simple homogeneous model with Coulombic interactions and first-order multi-band coupling to examine the role of effective mass and relative permittivity in relation to the critical carrier density, where compressibility turns negative. We demonstrate that the population of a second band, along with the presence of inter-band coupling, can dramatically change the cross-over carrier density. Given the difficulty in determining and confirming multi-band electronic systems, this model provides a potential method for identifying multi-band electronic systems using precise bulk electronic properties measurements. To help illustrate this method, we apply our results to the observed NEC in the 2D electron gas at the interface of LaAlO$_3$/SrTiO$_3$ (LAO/STO) and determine that, for the known parameters of LAO/STO, the system is likely a realization of a two-band 2D electron gas. Furthermore, we provide general limits on the inter-band coupling with respect to the electronic band population.

description: We explore the \emph{Liouvillian} non-integrability criteria for long quiver gauge theories those preserve $ \mathcal{N}=1 $ SUSY in $ 5d $. We probe type IIB solutions with (an $ AdS_6 $ factor) semi-classical strings which capture the strong coupling dynamics of $ \mathcal{N}=1 $ SCFTs in $ 5d $. Our analysis reveals an underlying non-integrable structure within some sub-sector of these $ 5d $ SCFTs. To solidify our claim, we complement our analytic results through numerics. We estimate various chaos indicators for the phase space which confirm the onset of a \emph{chaotic} motion for these type IIB strings.

Giant Magnons under NS-NS and Melvin Fields

Subjects: subject: High Energy Physics - Theory (hep-th)

description: The giant magnon is a rotating spiky string configuration which has the same dispersion relation between the energy and angular momentum as that of a spin magnon. In this paper we investigate the effects of the NS-NS and Melvin fields on the giant magnon. We first analyze the energy and angular momenta of the two-spin spiky D-string moving on the $AdS_3\times S^1$ with the NS-NS field. Due to the infinite boundary of the AdS spacetime the D-string solution will extend to infinity and it appears the divergences. After adding the counter terms we obtain the dispersion relation of the corresponding giant magnon. The result shows that there will appear a prefactor before the angular momentum, in addition to some corrections in the sine function. We also see that the spiky profile of a rotating D-string plays an important role in mapping it to a spin magnon. We next investigate the energy and angular momentum of the one-spin spiky fundamental string moving on the $R \times S^2$ with the electric or magnetic Melvin field. The dispersion relation of the corresponding deformed giant magnon is also obtained. We discuss some properties of the correction terms and their relations to the spin chain with deformations.

description: Abstract
In plants, the biosynthetic pathways of some specialized metabolites are partitioned into specialized or rare cell types, as exemplified by the monoterpenoid indole alkaloid (MIA) pathway of Catharanthus roseus (Madagascar Periwinkle), the source of the anti-cancer compounds vinblastine and vincristine. In the leaf, the C. roseus MIA biosynthetic pathway is partitioned into three cell types with the final known steps of the pathway expressed in the rare cell type termed idioblast. How cell-type specificity of MIA biosynthesis is achieved is poorly understood. Here, we generated single-cell multi-omics data from C. roseus leaves. Integrating gene expression and chromatin accessibility profiles across single cells, as well as transcription factor (TF) binding site profiles, we constructed a cell-type-aware gene regulatory network for MIA biosynthesis. For biosynthetic genes without known regulators, we showcased promoters of biosynthetic genes that are exclusively accessible in the corresponding cell types. Using motif enrichment analysis, co-expression across cell types, and functional validation approaches, we discovered a novel idioblast specific TF (Idioblast MYB1, CrIDM1) that activates expression of late-stage vinca alkaloid biosynthetic genes in the idioblast. The cell-type-aware gene regulatory network for C. roseus not only provides insights into cell-type-specific gene expression of specialized metabolism but also the first documented cell-type-specific TF that regulates the expression of two idioblast specific biosynthetic genes within an idioblast metabolic regulon.

description: The aim of the present thesis was the study of the legal share and its judicial protection in case of violation. To begin with, we examined the constitution of the legal share through the course of the continental european history, until the modern ages, as it was established in the contemporary greek civil code, as well as the reasons that forged this constitution. Then we studied the traits, the nature and the systemic function of the legal share in the greek law system. Moreover, we cited the numerous cases of violation of the right to the legal share, along with their peculiarities, as well as the solutions applied especially by the Supreme Court of Justice. In addition, we analyzed the different legal actions the legal beneficiary can bring in order to protect his right, studying them from the perspective of the substantial and the procedural civil law. Finally, we examined the nature and the function of the certificate of inheritance, evaluating its importance in transactions between the beneficiary of the legal share and other persons, that pertain to objects of the heritage.

description: We realize, for the first time, a non-Abelian gauge theory with both gauge and matter fields on a quantum computer. This enables the observation of hadrons and the calculation of their associated masses. The SU(2) gauge group considered here represents an important first step towards ultimately studying quantum chromodynamics, the theory that describes the properties of protons, neutrons and other hadrons. Quantum computers are able to create important new opportunities for ongoing essential research on gauge theories by providing simulations that are unattainable on classical computers. Our calculations on an IBM superconducting platform utilize a variational quantum eigensolver to study both meson and baryon states, hadrons which have never been seen in a non-Abelian simulation on a quantum computer. We develop a resource-efficient approach that not only allows the implementation of a full SU(2) gauge theory on present-day quantum hardware, but further lays out the premises for future quantum simulations that will address currently unanswered questions in particle and nuclear physics.

description: Background: Highly active anti-retroviral therapy (HAART) has brought significant change in reducing morbidity and mortality among children living with HIV/AIDS. Decisions concerning initiation and/or shifting of antiretroviral therapy (ART) are guided by monitoring the laboratory parameters of plasma HIV RNA (viral load) and CD4+ T cell count in addition to the patient’s over all clinical response. The demonstrations of the prognostic value of the CD4 cell count was of major importance in the development of therapeutic strategies. Therefore, the objective of this study was to assess factors predicting suboptimal CD4 cell recovery during first six months of ART. Methods: The study is retrospective cross sectional study to assess factors predicting suboptimal CD4 cell recovery. Medical records of patients’ were retrieved and important variables are captured to standard questionnaire tool. T-test is used to assess changes in CD4 cell count after initiation of ART. Binary logistic and multiple regressions were used to assess factors predicting CD4 cell recovery. Results: Data of 360 children were analyzed. CD4 cell count at the start of HAART ranged from 3-2003 cell/mL with an interquartile range of 231-317 cell/mL. After 6 months of HAART, the CD4 cell count has increased ranging from 71-2300 cell/mL with inter quartile range of 458-612 cell/mL and mean CD4 cell count difference of 230, 95%CI (199.414-260.613); P<0.001. Advanced clinical stage of the disease, severe degree of immunosupression, presence of anemia, presence of chronic diarrhea at base line, poor weight gain during first six months of HAART adversely affect the trends of CD4 recovery. Conclusion: Our study demonstrated that advanced clinical stage of the disease, severe degree of immunosupression, presence of anemia at baseline and presence of chronic diarrhea, poor weight gain during first six months of HAART were factors adversely affect the trends of CD4 recovery.

description: A mechanism of formation of small-scale inhomogeneities in spatial distributions of aerosols and droplets associated with clustering instability in the atmospheric turbulent flow is discussed. The particle clustering is a consequence of a spontaneous breakdown of their homogeneous space distribution due to the clustering instability, and is caused by a combined effect of the particle inertia and a finite correlation time of the turbulent velocity field. In this paper a theoretical approach proposed in Phys. Rev. E 66, 036302 (2002) is further developed and applied to investigate the mechanisms of formation of small-scale aerosol inhomogeneities in the atmospheric turbulent flow. The theory of the particle clustering instability is extended to the case when the particle Stokes time is larger than the Kolmogorov time scale, but is much smaller than the correlation time at the integral scale of turbulence. We determined the criterion of the clustering instability for the Stokes number larger than 1. We discussed applications of the analyzed effects to the dynamics of aerosols and droplets in the atmospheric turbulent flow.

description: Background: Ethiopia is the second most populous country in Africa. Total Fertility Rate of Ethiopia is 4.6 children per women, population growth rate is estimated to be 2.7% per year and contraceptive prevalence rate is only 29% while the unmet need for family planning is 34%. The prevalence of long acting contraceptive methods (LACMs) is very low. Objective: The main objective of this study is to determine the level of utilization of long acting contraceptive methods and explore its determinants among married women of reproductive age in Adaba town, West Arsi Zone, Oromia regional State, Ethiopia. Methods: Community based cross sectional survey complemented with a qualitative method was conducted from March, 2016 to April, 2016 on selected Samples of 693 married women of reproductive age. Interviewer administered structured questionnaire was used to collect the data. Data were analyzed by using SPSS version 21. Logistic regression was carried out to see the effect of the independent variables on dependent variable. Results: Long acting reversible contraceptive method utilization was 30.3%. Among the variables age of women and being involved in daily laborer type of occupation were found positively associated with long acting contraceptive methods use with the odds of age of women [AOR (95% CI) = 6.26 (1.92-20.45), 5.18 (1.63-16.5), 9.15 (2.57-32.52)], Occupation of women (daily laborer compared to housewife) [AOR (95% CI) = 5.75 (2.45-13.49)]. Similarly, educational status of being completed grade twelve compared to illiterate were found positively associated with long acting contraceptive methods use with the odds of educational status of women [AOR (95% CI) = 4.42 (1.11-17.62)], and also mothers who disagree IUD influences normal daily activity (i.e., positive attitudes towards long acting contraception) were 44.5 times [AOR = 44.5, (95% CI) = 9.13-216.8] more likely to utilize long acting reversible contraceptive than those who agree (had negative attitudes). Conclusion: Prevalence of long acting contraceptive use is low coverage. Age, educational level, occupational status of the women and attitude towards IUCD were determinant factors identified. So, Health communication on long acting contraceptives should be directed to women of adolescent age (15-19), women who cannot read and write and housewives. Effort should be made to influence the attitude of women on IUCD.

description: The present paper generalizes preceding papers of the author and opens a cycle of works concerning the general posing and solution in analytic form of the quantum-mechanical inverse scattering problem (for a given partial channel) in a nontraditional setting: the scattering wave function in the momentum representation is recovered immediately from the scattering data. The solution we find for the problem in question is given by a family of phase-equivalent wave functions with explicitly controlled functional-analytic arbitrariness. This arbitrariness corresponds to the arbitrariness in the choice of phase-equivalent nonlocal potentials and causes the necessary to include some additional concepts of quantum measurement theory to a complete description of quantum-mechanical systems. The mathematical apparatus of the approach thus developed is illustrated by the example of describing the nucleon-nucleon interaction in uncoupled partial channels.

description: Το πολιτικό υποκείμενο είναι προϊόν κοινωνικής κατασκευής, είναι μία φαντασιακή διόπτρα κατανόησης του κόσμου. Το πολιτικό υποκείμενο αντιλαμβάνεται τον αντικειμενικό κόσμο μέσα από την υποκειμενική θέση που βρίσκεται σε αυτόν. Το άτομο αποκτά ένα πολιτικό περιεχόμενο μέσα από κοινωνικές εμπειρίες, γνώση και πληροφορίες που λαμβάνει στη διάρκεια της ζωής του. Οι πολιτικές προσλαμβάνουσες δείχνουν να είναι η μοναδική αλήθεια του κόσμου τη στιγμή που ο κόσμος είναι υποκειμενικά αντικειμενικός. Το κοινωνικό φαντασιακό είναι μοχλός ζωτικής σημασίας για την ύπαρξη του ίδιου του κόσμου, είναι ο άυλος κόσμος που δίνει ύλη στον κόσμο. Το κοινωνικό φαντασιακό κάνει προφανές το μη ορατό, αντικειμενοποιεί τον υποκειμενικό κόσμο του πολιτικού υποκειμένου. Τα μικροσύμπαντα του πολιτικού υποκειμένου ανήκουν σε ένα συμπαντικό όλον. Η πολιτική-κοινωνική δράση του υποκειμένου πραγματώνεται πάνω στην κοινωνική γραμμικότητα τη στιγμή που είναι η κοινωνική γραμμικότητα. Τέλος, στην προβληματική μας είδαμε τη διαλεκτική σχέση αυτών των δύο εννοιών, «πολιτικό υποκείμενο» και «κοινωνικό φαντασιακό». Οι δύο έννοιες είναι υποκειμενικά αντικειμενικές, καταλαμβάνουν φαντασιακό χωροχρόνο και αντικειμενοποιούν το μη ορατό. Είναι στη φύση του πολιτικού υποκειμένου να παράγει πολιτική, να κατανοεί στον κόσμο με εργαλεία της φαντασίας του, να βλέπει και να εξηγεί αυτό που η κβαντική φυσική αδυνατεί να κάνει. Η σχέση αυτή δεν μπορεί παρά να είναι άπειρη.
description: The political subject is a product of social fabrication, it is a fantasy view of the world. The political subject understands the objective world through the subjective position in it. The person acquires a political content through social experiences, knowledge and information that he receives during his or her life. Recruiting politicians appear to be the only truth of the world when the world is subjectively objective. Social imaginary is a lever vital to the existence of the world itself, it is the immaterial world that gives substance to the world. The social imaginary makes it obvious that it is not visible, it objectively reflects the subjective world of the political subject. The micro-entities of the political subject belong to a universal universe. The subject's political-social action is based on social linearity at the moment when it is social linearity. Finally, in our problem we have seen the dialectic relationship of these two concepts, "political subject" and "social imaginary". The two concepts are subjectively objective, occupy imaginary space-time and objectify the invisible. It is in the nature of the political subject to produce politics, to understand the world with tools of its imagination, to see and explain what quantum physics can not do. This relationship can only be infinite.

description: Objective: To determine the prevalence and associated factors with the maternal delay in seeking emergency obstetrics services among pregnant women, Arsi Zone, Oromiya, Ethiopia, 2016. Methods: A Facility based Cross-sectional study design using a quantitative method was conducted at public health facilities of Arsi Zone. Sample size, 847 was determined using a single population proportion formula. A total of 10 health centers which provide obstetric care selected randomly and sample size proportionally allocated to each facility. Data entered in Epi Info version 3.3.2 software and exported to SPSS version 20 for statistical analysis. P<0.05 considered to declare a statistically significant variable with a 95% confidence interval. Result: From the total 775 participants, 203 (27.2%) of the respondents reported that they faced problem in making a decision to seek emergency obstetric care. The mean time for delay was 90 minutes with a range of 30 minutes to 18 hours. Maternal age, educational level, monthly income, and ANC follow up status were significant predictors of maternal delay in seeking emergency obstetric care. Conclusion: Husbands took the lines to share in making the decision to seek obstetric care. This implies independent decision-making power of women on their own health is low. In order to address maternal delay one health extension workers along with health centers staffs, district officers and programmers should give emphasis for awareness creation, income generating mechanism and capacitating decision making the power of mothers need to be strengthened and expanded in the community.

Institutional Delivery Service Utilization and Associated Factors among Women of Child Bearing Age at Boset Woreda, Oromia Regional State, Central Ethiopia
Creators: name: Taye Shigute, Solomon Tejineh
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: Background: Evidence has shown access to skilled attendance at birth averting nearly 16-33% maternal deaths. Despite concerted effort to increase access and importance of institutional delivery in preventing maternal death, only 46% and 15% of developing nations and Ethiopian national deliveries, respectively delivered in health facilities that makes assessment of the barriers to health facility delivery important in the study setup. Objective: To assess institutional delivery magnitude and associated factors among mothers delivered in the past 12 months in Boset Woreda, Ethiopia. Methods: A community based cross-sectional study was employed. Systematic random sampling was used to select participants. Data collected using Interviewer administered questionnaire and entered Epi Info 7.1 and analyzed using SPSS version 20.0, p-value 0.05 used to declare statistical significance. Results: A total of 589 women were participated in this study. The mean age of the respondents was 26 years (+5 SD). Educational status of 321 (54.0%) were read and write, while 198 (34.0%) were illiterate. The magnitude of institutional delivery utilization is found 60%. From the study, primary and above educational status (AOR: 2.1; (95%CI: 10.1, 4.70), occupation other than house wife (merchant, employee, etc.) (AOR:1.9; 95%CI:1.12,4.01), age ≥ 18 years during their first marriage (AOR: 1.5; 95%CI:1.21,2.30), age ≥ 18 years during their first pregnancy (AOR: 1.8; 95%CI:1.13,3.35), primigravida (AOR: 2.5; 95%CI: 1.57,3.99), distance from health facility <1 hour (AOR: 15; 95%CI: 9.34,27.11), and women decision maker for place of delivery (AOR: 3.4; 95%CI: 1.86,6.27) were statistically significant predictors contributing for better institutional delivery utilization. Conclusion and Recommendation: Institutional delivery service utilization was found to be higher compared to other areas. Finding revealed education, occupation, age at marriage and distance from facility independently affect institutional delivery. Efforts should be made to increase maternal education access to facility to improve institutional delivery utilization.

description: The effects of local B-cation (Ti, Zr) distribution and octahedral tilting on the pre-edge structure in the Ti X-ray absorption K-spectra of the CaTi1-xZrxO3 perovskite solid solutions were investigated. Experimental spectra for the disordered CaTi1-xZrxO3 samples revealed systematic variations of the pre-edge peak intensities with the x-values. Multiple-scattering calculations using 75-atom clusters Ti(TiO6)6-n(ZrO6)nCa8O24 were conducted to interpret these differences. The origin of the lowest unoccupied states in the conduction band of the CaTi1-xZrxO3 was determined from the analyses of X-ray absorption near-edge structure of the O K-edge. The calculations reproduced the experimental spectra and demonstrated that the differences in the intensities of certain pre-edge feature are dominated by the probability of finding a Zr atom in the first B-cation coordination sphere around the absorbing Ti. The pre-edge structure appeared to be sensitive to small changes in the value of this probability, so that the pre-edge intensities could be used effectively to compare the extent of local B-site order in perovskite solid solution samples having similar chemical composition but processed differently.

description: A wide range of code intelligence (CI) tools, powered by deep neural networks, have been developed recently to improve programming productivity and perform program analysis. To reliably use such tools, developers often need to reason about the behavior of the underlying models and the factors that affect them. This is especially challenging for tools backed by deep neural networks. Various methods have tried to reduce this opacity in the vein of "transparent/interpretable-AI". However, these approaches are often specific to a particular set of network architectures, even requiring access to the network's parameters. This makes them difficult to use for the average programmer, which hinders the reliable adoption of neural CI systems. In this paper, we propose a simple, model-agnostic approach to identify critical input features for models in CI systems, by drawing on software debugging research, specifically delta debugging. Our approach, SIVAND, uses simplification techniques that reduce the size of input programs of a CI model while preserving the predictions of the model. We show that this approach yields remarkably small outputs and is broadly applicable across many model architectures and problem domains. We find that the models in our experiments often rely heavily on just a few syntactic features in input programs. We believe that SIVAND's extracted features may help understand neural CI systems' predictions and learned behavior.

Year: 2023

description: The effect of internal and external parasitism on productivity of dairy cattle is considered as the most unidentifiable underlying cause for low productivity. Parasites are found externally viz., ticks, mites, flies and internally such as worms, protozoa etc., are a major cause of disease and production loss. Various species of protozoans and helminths cause economically important parasitic diseases with economic loss by decrease in milk production, decreased weight gain, treatment costs and mortality.  While abortion losses, organ condemnation, carcass weight loss and decreases hide value, and fecundity are other effects. A major concern in the control of parasitic diseases is the development of resistance by worms, flies, ticks etc. The parasitic challenge experienced and the outcome of that challenge is a dynamic one in which environment, management practices, including housing or grazing management, nutritional status, the host's ability to develop effective immunity and the speed with which this can occur, play a significant role.

description: In this thesis we present two multimedia architectures and a data retrieval model for supporting simultaneously multiple clients requesting files of different playback rates. After reviewing some theoretical background from previous research, we study the performance of the architectures in terms of the maximum number of concurrent video streams they can support using circular SCAN disk scheduling policy. We present new techniques, namely, the maximum operation set and the Rate-based Buffer Weighting Scheme, not only to adapt the system to streams of different playback rates but also to relieve the processing load on the server. Next, we devise a new way of designing the Admission Control for both architectures. The new Admission Control is simple, effective and efficient. Finally we compare the merits of the architectures in terms of throughput, contention, client buffer size and reliability.

description: Information extraction from document images has received a lot of attention recently, due to the need for digitizing a large volume of unstructured documents such as invoices, receipts, bank transfers, etc. In this paper, we propose a novel deep learning architecture for end-to-end information extraction on the 2D character-grid embedding of the document, namely the \textit{Multi-Stage Attentional U-Net}. To effectively capture the textual and spatial relations between 2D elements, our model leverages a specialized multi-stage encoder-decoders design, in conjunction with efficient uses of the self-attention mechanism and the box convolution. Experimental results on different datasets show that our model outperforms the baseline U-Net architecture by a large margin while using 40\% fewer parameters. Moreover, it also significantly improved the baseline in erroneous OCR and limited training data scenario, thus becomes practical for real-world applications.

description: Angular-dependent in-plane magnetoresistance (AMR) for single crystal $Na_{0.34}(H_3O)_{0.15}CoO_2$ with charge ordering is studied systematically. The anisotropic magnetoresistance shows a twofold symmetry at high temperature with rotating H in the Co-O plane, while a sixfold symmetry below a certain temperature ($T_ρ$). At $T_ρ$, the symmetry of AMR changes from twofold to fourfold with rotating magnetic field (H) in the plane consisting of the current and c-axis. The variation of AMR symmetry with temperature arises from the subtle changes of the spin structure. These results give a direct evidence for the itinerant electrons directly coupled to the localized spins.

description: In this work, we will present a physically consistent theory to derive the governing equations of the Large Eddy Simulation (LES) framework based on first principles rather than the motivation to conduct computationally affordable simulations of turbulent flows. Therefore, we assume that a coarse-grained fluid element, subsequently called super fluid element, can be locally defined comprising a large number of smaller elementary fluid elements. Then, similar to non-equilibrium molecular dynamics (NEMD), in which the transport equations of an elementary fluid element can be consistently reconstructed from the local, collective dynamics of molecules, the transport equations of a super fluid element can be derived from the local, collective dynamics of elementary fluid elements. Interestingly, we find: (a) Favre filtering is a physical consistency condition, (b) why Boussinesq's hypothesis in conjunction with eddy viscosity models is commonly employed in LES and (c) that the LES framework might be more than a numerical turbulence model for computational fluid dynamics (CFD).
