description: Frequency- and time-domain Brillouin scattering spectroscopy are powerful tools to read out the mechanical properties of complex systems in material and life sciences. Indeed, coherent acoustic phonons in the time-domain method offer superior depth resolution and a stronger signal than incoherent acoustic phonons in the frequency-domain method. However, it does not allow multichannel detection and, therefore, falls short in signal acquisition speed. Here, we present Brillouin scattering spectroscopy that spans the time and frequency domains to allow the multichannel detection of Brillouin scattering light from coherent acoustic phonons. Our technique maps the time-evolve Brillouin oscillations at the instantaneous frequency of a chromatic-dispersed laser pulse. The spectroscopic heterodyning of Brillouin oscillations in the frequency domain enhances the signal acquisition speed by at least 100-fold over the time-domain method. As a proof of concept, we imaged heterogeneous thin films and biological cells over a wide bandwidth with nanometer depth resolution. We, therefore, foresee that our approach catalyzes future phonon spectroscopy toward real-time mechanical imaging.

Line as a Visual Sentence: Context-aware Line Descriptor for Visual Localization

description: Along with feature points for image matching, line features provide additional constraints to solve visual geometric problems in robotics and computer vision (CV). Although recent convolutional neural network (CNN)-based line descriptors are promising for viewpoint changes or dynamic environments, we claim that the CNN architecture has innate disadvantages to abstract variable line length into the fixed-dimensional descriptor. In this paper, we effectively introduce Line-Transformers dealing with variable lines. Inspired by natural language processing (NLP) tasks where sentences can be understood and abstracted well in neural nets, we view a line segment as a sentence that contains points (words). By attending to well-describable points on aline dynamically, our descriptor performs excellently on variable line length. We also propose line signature networks sharing the line's geometric attributes to neighborhoods. Performing as group descriptors, the networks enhance line descriptors by understanding lines' relative geometries. Finally, we present the proposed line descriptor and matching in a Point and Line Localization (PL-Loc). We show that the visual localization with feature points can be improved using our line features. We validate the proposed method for homography estimation and visual localization.

Optimization and characterization of antioxidant activity from green tea (Camellia sinensis) and evaluation of its preservative effect
Creators: name: Shumi, Shimelis
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: The study was conducted with the aim of optimizing and characterizing antioxidant activity of Camellia sinensis and evaluating its preservative effect on Niger seed and Soybean oils. Camellia was prepared by investigating the effect of distilled water concentrations of 100, 150, and 200ml, extraction temperature 80, 85 and 90 ℃ and contact time of 10, 35 and 60 min on its antioxidant activity and extract yield. Based on ANOVA analysis, extraction parameters have significant positive effect (P<0.05) on Camellia antioxidant activity and its extract yield. The best levels of extraction parameters for higher antioxidant activity and extract yield were distilled water concentration of 200ml for 60min at 90 ℃. As DPPH free radical scavenging activity results shown the highest antioxidant activity of Camellia was 96.1%. On the other hand extraction parameters (solvent concentrations, extraction temperature & contact time) were optimized. The best extraction conditions were 200ml, 88 ℃ and 35 min and the results were yield (79.850%) and Antioxidant activity (96.9810%). The preservative effect of Camellia was also studied by performing Free Fatty Acids, Peroxide Value/Acid value on Niger seed and Soybean oils. In the study, all samples were treated with 0, 1 and 2ml levels of Camellia extract and analysis were conducted on weekly basis. Compared to Camellia extract containing Niger seed and Soybean oils, control sample showed higher Free Fatty Acid and Peroxide Values in each storage weeks. Samples treated with 2ml Camellia extract were shown lower Free Fatty Acid and Peroxide Values in each storage weeks. Based on the results, samples with 2ml Camellia extract significantly improved the oxidative stability of Niger seed and Soybean oils. Hence, Camellia has antioxidant activity and preservative effect as evaluated on Niger seed and Soybean oils. Keywords: Antioxidant activity, green tea extract, Camellia sinensis, response surface methodology, DPPH free radical scavenging activity, preservative effect.

Solving Multistage Stochastic Linear Programming via Regularized Linear Decision Rules: An Application to Hydrothermal Dispatch Planning

description: The solution of multistage stochastic linear problems (MSLP) represents a challenge for many application areas. Long-term hydrothermal dispatch planning (LHDP) materializes this challenge in a real-world problem that affects electricity markets, economies, and natural resources worldwide. No closed-form solutions are available for MSLP and the definition of non-anticipative policies with high-quality out-of-sample performance is crucial. Linear decision rules (LDR) provide an interesting simulation-based framework for finding high-quality policies for MSLP through two-stage stochastic models. In practical applications, however, the number of parameters to be estimated when using an LDR may be close to or higher than the number of scenarios of the sample average approximation problem, thereby generating an in-sample overfit and poor performances in out-of-sample simulations. In this paper, we propose a novel regularized LDR to solve MSLP based on the AdaLASSO (adaptive least absolute shrinkage and selection operator). The goal is to use the parsimony principle, as largely studied in high-dimensional linear regression models, to obtain better out-of-sample performance for LDR applied to MSLP. Computational experiments show that the overfit threat is non-negligible when using classical non-regularized LDR to solve the LHDP, one of the most studied MSLP with relevant applications. Our analysis highlights the following benefits of the proposed framework in comparison to the non-regularized benchmark: 1) significant reductions in the number of non-zero coefficients (model parsimony), 2) substantial cost reductions in out-of-sample evaluations, and 3) improved spot-price profiles.

Attributed Graph Modeling with Vertex Replacement Grammars

Subjects: subject: Social and Information Networks (cs.SI)

description: Recent work at the intersection of formal language theory and graph theory has explored graph grammars for graph modeling. However, existing models and formalisms can only operate on homogeneous (i.e., untyped or unattributed) graphs. We relax this restriction and introduce the Attributed Vertex Replacement Grammar (AVRG), which can be efficiently extracted from heterogeneous (i.e., typed, colored, or attributed) graphs. Unlike current state-of-the-art methods, which train enormous models over complicated deep neural architectures, the AVRG model is unsupervised and interpretable. It is based on context-free string grammars and works by encoding graph rewriting rules into a graph grammar containing graphlets and instructions on how they fit together. We show that the AVRG can encode succinct models of input graphs yet faithfully preserve their structure and assortativity properties. Experiments on large real-world datasets show that graphs generated from the AVRG model exhibit substructures and attribute configurations that match those found in the input networks.

description: We consider the possibility that dark matter (DM) only interacts with the Standard Model leptons, but not quarks at tree level, and analyze the future lepton collider prospects of such leptophilic DM in the monophoton and mono-$Z$ (both leptonic and hadronic) channels. Adopting a model-independent effective field theory framework, we consider all possible dimension-six operators of scalar-pseudoscalar (SP), vector-axial vector (VA), and tensor-axial tensor (TAT) types for a fermionic DM and derive the collider sensitivities on the effective cutoff scale $Λ$ as a function of the DM mass. As a concrete example, we take the beam configurations of the International Linear Collider with $\sqrt s=1$ TeV and $8$ ab$^{-1}$ integrated luminosity, including the effect of beam polarization, and show that it can probe leptophilic DM at $3σ$ level up to $Λ$ values of $6.6$, $8.8$, and $7.1$ TeV for the SP-, VA- and TAT-type operators, respectively. This is largely complementary to the direct and indirect searches for leptophilic DM and can potentially provide the best-ever sensitivity in the low-mass DM regime.

Effect of Blend ratio and Extrusion Operating Conditions on Product Quality of Sorghum/Soybean Extrudate
Creators: name: Tefera, Chernet
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2012

description: In this work, the effects of full fat soybean flour addition and extrusion operating conditions (barrel temperature and feed moisture) on quality characteristics of sorghum flour extrudates were studied, with the objective of developing ready-to-eat extruded product. A pilot scale twin screw food extruder was used for the extrusion. Full factorial design was employed to investigate the effect of blend ratio (95:05, 90:10 and 85:15 sorghum and soybean respectively), barrel temperature (120, 135 and 150 °C) and feed moisture levels (14, 16 and 18%) on the physical (radial expansion ratio and bulk density) and functional (water absorption index and water solubility index) properties of the extrudates. Maximum radial expansion ratio (two times) and minimum bulk density extrudate was obtained at 90:10 blend ratio. In addition to this lower blend ratio (95:05) registered lower water absorption index and higher water solubility index. Taking into consideration the extrusion operating conditions, increasing barrel temperature (120-150 °C) and feed moisture (14-18%) decreased the radial expansion ratio and water solubility index while increasing the water absorption index. Later on, the results of the sensory evaluation (color, flavor, texture and overall acceptability) revealed that increased blend ratio, barrel temperature and feed moisture content decreased the level of acceptance yet the results also showed that the extruded product from 90:10 blend ratio, 120 °C barrel temperature and 14% feed moisture is still an acceptable product with an overall acceptability of 7.1. It was then demonstrated from the optimization result that it is possible to produce good extruded product. The extruded product from 91.8:8.2 (sorghum and soybean respectively), 120 °C barrel temperature and 14% feed moisture was selected as best formulation to yield a protein rich extruded product with desirable attributes like higher radial expansion ratio (2.02), lower bulk density (0.072), higher water absorption index (4.53) and higher sensory acceptability (7.327).

description: The study of tunneling splitting is fundamental to get insight into the dynamics of a multitude of molecular systems. In this paper, a novel approach to the analysis of the ground-state tunneling splitting is presented and explicitly applied to one-dimensional systems. The isomorphism between the Fokker-Planck-Smoluchowski operator and the Born-Oppenheimer quantum Hamiltonian is the key element of this method. The localization function approach, used in the field of stochastic processes to study the Kramers problem, leads to a simple, yet asymptotically justified, integral approximation for the tunneling splitting. The comparison with exact values of the tunneling splittings shows a much better accuracy than WKB semiclassical estimates.

Nonparametric Estimation for I.I.D. Paths of a Martingale Driven Model with Application to Non-Autonomous Financial Models
Creators: name: Marie, Nicolas
Publisher: name: arXiv
Year: 2021
Subjects: subject: Statistics Theory (math.ST)

description: This paper deals with a projection least squares estimator of the function $J_0$ computed from multiple independent observations on $[0,T]$ of the process $Z$ defined by $dZ_t = J_0(t)d\langle M\rangle_t + dM_t$, where $M$ is a continuous and square integrable martingale vanishing at $0$. Risk bounds are established on this estimator, on an associated adaptive estimator and on an associated discrete-time version used in practice. An appropriate transformation allows to rewrite the differential equation $dX_t = V(X_t)(b_0(t)dt +σ(t)dB_t)$, where $B$ is a fractional Brownian motion of Hurst parameter $H\in [1/2,1)$, as a model of the previous type. So, the second part of the paper deals with risk bounds on a nonparametric estimator of $b_0$ derived from the results on the projection least squares estimator of $J_0$. In particular, our results apply to the estimation of the drift function in a non-autonomous Black-Scholes model and to nonparametric estimation in a non-autonomous fractional stochastic volatility model.

Evaluation and optimization of process conditions for Lime saccharate clarification in the manufacture of plantation white sugar:The case of Metahara sugar Factory
Creators: name: Bazezew, Abayneh
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2011

description: This paper analyses the possibility to adopt lime saccharate clarification in Metahara Sugar Factory and also tries to find optimum process conditions for better juice purification. Mixed juice samples of 5 l each were taken from weighed mixed juice pumps' return line and pretreated so as to be used for settling test. To get the targeted P2O5 content in juice, calculated amount of phosphoric acid was added to the sample and subjected to heating to 750C.Then, the pH was raised to the pH of 8.5-9.5 by the addition of lime or lime saccharate, heated to the boiling point. The prepared sample was taken and poured in to the 1000 ml graduated cylinder containing flocculant (separan).The required parameters were determined from the clarified juice sample. The data obtained from the comparative experiments were subjected to statistical analysis using design expert software whereby the significance was set at 5% level. The result of the experiment has shown that mixed juice sample from different combinations of cane varieties did not show any significant variation in quality parameters at 5% significance level. At P2O5 content of 300ppm and separan concentration of 3ppm, the upper limit of the preliming pH of 9.5 gave better results for lime saccharate such as purity of 84.7%, CaO of 936ppm, and turbidity of 477TU. But, when the P2O5 content was increased to 350ppm, at separan concentration at 3 ppm, the mid value, pH of 9, gave better results i.e, purity of 84.8%, turbidity of 163 Tu, settling rate of 10 cm/min, reducing content of 0.52%. On the other hand, when the P2O5 content was raised to 350 ppm with a separan concentration lowered to 1ppm, the lower limit value of PH=8.5 gave better values. Furthermore, analysis of data of both treatments using the design expert software has proved to be significant for all the parameters except that of CaO. The analysis had also shown that the optimum process parameters of clarification were identified to be pH=8.87, P2O5=321.15 and separan concentration of 3 ppm, which gave acceptable values of the response variables considered. Using the optimum pH, evaluation of the chemical consumption revealed that there is about 71% reduction in lime consumption which can be taken as a positive outcome to bring cost reduction and increased profitability to Metahara Sugar Factory in particular and all other sugar factories in general. Key words:Sugar,Clarification,Lime saccharate,Optimization.

description: Fixed $F$-numbers reduce grating lobe artifacts in fast pulse-echo ultrasound imaging. Such $F$-numbers result in dynamic receive subapertures whose widths vary with the focal position. These subapertures, however, ignore useful low-frequency components in the excluded radio frequency (RF) signals and, thus, reduce the lateral resolution. Here, we propose a frequency-dependent $F$-number to simultaneously suppress grating lobe artifacts and maintain the lateral resolution. This $F$-number, at high frequencies, reduces the receive subaperture to remove spatially undersampled components of the RF signals and suppress grating lobes. The $F$-number, at low frequencies, enlarges the receive subaperture to use the components of all RF signals and maintain the lateral resolution. Experiments validated the proposed $F$-number and demonstrated improvements in the contrast and the widths of wire targets of up to 3.2 % and 12.8 %, respectively.

description: The computing device deployment explosion experienced in recent years, motivated by the advances of technologies such as Internet-of-Things (IoT) and 5G, has led to a global scenario with increasing cybersecurity risks and threats. Among them, device spoofing and impersonation cyberattacks stand out due to their impact and, usually, low complexity required to be launched. To solve this issue, several solutions have emerged to identify device models and types based on the combination of behavioral fingerprinting and Machine/Deep Learning (ML/DL) techniques. However, these solutions are not appropriated for scenarios where data privacy and protection is a must, as they require data centralization for processing. In this context, newer approaches such as Federated Learning (FL) have not been fully explored yet, especially when malicious clients are present in the scenario setup. The present work analyzes and compares the device model identification performance of a centralized DL model with an FL one while using execution time-based events. For experimental purposes, a dataset containing execution-time features of 55 Raspberry Pis belonging to four different models has been collected and published. Using this dataset, the proposed solution achieved 0.9999 accuracy in both setups, centralized and federated, showing no performance decrease while preserving data privacy. Later, the impact of a label-flipping attack during the federated model training is evaluated, using several aggregation mechanisms as countermeasure. Zeno and coordinate-wise median aggregation show the best performance, although their performance greatly degrades when the percentage of fully malicious clients (all training samples poisoned) grows over 50%.

description: By highlighting the regions of the input image that contribute the most to the decision, saliency maps have become a popular method to make neural networks interpretable. In medical imaging, they are particularly well-suited to explain neural networks in the context of abnormality localization. However, from our experiments, they are less suited to classification problems where the features that allow to distinguish between the different classes are spatially correlated, scattered and definitely non-trivial. In this paper we thus propose a new paradigm for better interpretability. To this end we provide the user with relevant and easily interpretable information so that he can form his own opinion. We use Disentangled Variational Auto-Encoders which latent representation is divided into two components: the non-interpretable part and the disentangled part. The latter accounts for the categorical variables explicitly representing the different classes of interest. In addition to providing the class of a given input sample, such a model offers the possibility to transform the sample from a given class to a sample of another class, by modifying the value of the categorical variables in the latent representation. This paves the way to easier interpretation of class differences. We illustrate the relevance of this approach in the context of automatic sex determination from hip bones in forensic medicine. The features encoded by the model, that distinguish the different classes were found to be consistent with expert knowledge.
The Effect of Blend Proportion and Baking Condition on the Quality of Cookie Made from Taro and Wheat Flour Blend
Creators: name: Tekle, Abinet
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2009

description: The influence of blending proportion of taro and wheat flour and baking temperature on the physicochemical characteristics and sensory qualities of cookie made from taro-wheat flour blend was investigated. Taro and wheat flour were blended using 33.33, 66.67 and 100% proportion using mixture simplex lattice design whereas 140, 150 and 160°C baking temperature was used for baking. The physicochemical characteristics of cookies were evaluated in terms of proximate composition, energy value, water absorption capacity (WAC), oil absorption capacity (OAC), cookie diameter and thickness, spread ratio and cookie breaking strength (texture). The cookie sensory qualities were evaluated in terms of color, flavor, crispiness and overall acceptability. Increase in the taro flour proportion increased the crude fiber, carbohydrate and ash content of the cookies and resulted in a decrease in the protein, fat, moisture content and energy value of the cookie. Temperature only had a significant effect on the moisture and carbohydrate content of the cookies and not on protein, fat, crude fiber and ash content of the cookies. Breaking strength of the cookies significantly (p<0.05) increased whereas cookie diameter, thickness and spread ratio significantly decreased with an increase in taro flour proportion. On the other hand, increase in baking temperature, significantly (p<0.05) increased cookie diameter and thickness. The WAC and OAC were observed to increase with an increase in taro flour proportion in the composite. The sensory quality scores of cookie decreased significantly with increase in taro flour proportion. Moreover, cookies baked at 1600C had low sensory scores for color and flavor as compared those baked at 140 and 150°C. The results of overall acceptability confirmed that replacing of wheat flour with taro flour up to 33.33% for cookie baking was fairly acceptable. Significant decrease in the oxalate content of the cookies with an increase in the taro flour proportion was also observed. The 33.33% taro flour cookie was found not to be significantly different from the control cookies with all quality parameters except with protein, ash, carbohydrate, gross energy and crude fiber content. viii In general, the study indicated that blending taro up to 33.33% with wheat flour and 150°C baking temperature could result in cookies of acceptable quality.

description: The equation of state of the triclinic compound 1,3,5-triamino-2,4,6-trinitrobenzene (TATB) as well as its second-order isothermal elastic tensor were computed through classical molecular dynamics simulations under various temperature and pressure conditions. Hydrostatic pressures similar to previous diamond anvil cell experiments were imposed within the range [0, 66] GPa and temperatures chosen between 100 and 900 K in conjunction with the most recent version of an all-atom fully-flexible molecule force field. The isothermal elastic constants were computed using the generalized Hooke's law by fitting Cauchy stress vs. linear strain curves. Along isobaric pathways, TATB single crystal stiffness is found to undergo linear softening, less pronounced at high pressure, while maintaining its elastic anisotropy. On the other hand, along an isothermal pathways, a non-linear increase is observed in the elastic constants with a significant decrease in anisotropy. Towards a precise mesoscopic modeling of TATB single crystal mechanical behavior, we provide "ready to plug-in" analytical formulations of the P,V,T equation of state and pressure-temperature dependent non-linear elasticity.
