Trace Weighted Hessian-Aware Quantization

Quantization can efﬁciently assist the deployment of neural networks on mobile systems with constrained resources. However, directly quantizing a model to ultra low precision could cause signiﬁcant accuracy degradation. Most of the works addressing this problem use ﬁrst order information, along with expensive AutoML search methods to ﬁnd the bit precision for different layers. Here we introduce trace weighted Hessian-aware Quantization, a new second order based method which does not require any expensive search methods. We provide theoretical results to show that the trace of the Hessian, under certain assumption, could be used to determine sensitivity of different layers to quantization, and we use this information to perform Hessian aware ﬁne-tuning. We test our second-order approach, and show that it exceeds industry-scale results which use expensive AutoML search methods. In particular, we present quantization results on ImageNet dataset for Inception-V3 (75.68% with 7.57MB model size) and ResNet50 (75.76% with 7.99MB model size). Both results are state-of-the-art for quantized models.
The active-passive continuous-wave terahertz imaging system

Active and passive terahertz (THz) imaging have recently become essential instruments of various THz applications. In this paper the active- and passive-mode THz imaging systems are studied and the hybrid active-passive THz imaging system is suggested. The concept of image contrast was used to compare the active and passive THz imaging results. In order to achieve better image quality the hybrid system is considered to be effective. The main advantage of the proposed system is the combination of the self-emitted radiation of the object with the back scattered source radiation. The experimental results demonstrate that the active-passive modality of THz imaging system allows retrieving maximum information about the object. An approach to synthesise the active-passive THz images was proposed using the false-color representation.
PROCEEDINGS OF THE 12 th WORLD RABBIT CONGRESS REDUCING ANTIMICROBIAL CONSUMPTION IN RABBIT FARMING IS FEASABLE: THE STATE OF PLAY IN ITALY

Rabbit industrial breading is the food production system with the highest consumption of antimicrobials (AMU). A cross-over study on AMU in industrial rabbit breeding was performed in 2018-2019 in 17 out of 32 herds previously investigated in 2010-2015. Raw data on AMU were standardized according to rabbit production (kg rabbit biomass sold for slaughter) and animal daily dose per kg body weight (ADD). Herd-level antimicrobial resistance (AMR) against eight antimicrobials was assessed in commensal Escherichia coli isolated from fresh faeces (five isolates per herd). The herd level AMR indicator was the mean antimicrobial resistance index (ARI) towards: aminosidine, cefotaxime, colistin, enrofloxacin, chloramphenicol, tetracycline, sulfadiazine. MICs were interpreted according to EUCAST epidemiologic cut offs. Over the study period there was no reduction of production of rabbits at slaughter age. Results showed a statistically significant (P < 0.001) decrease from 77.6, in 2010, to 27.0, in 2019, of the overall ADD consumption (-65%). The average consumption of antimicrobials was statistically significantly (P < 0.001) declining over the time period, involving all antimicrobial classes: aminoglycosides, bacitracines, betalactams, macrolides, pleuromutilines, polymyxins, quinolones, sulfonamides and tetracyclines. Compared to all herds surveyed in 2010-2015, there was a strong and statistically significant (P < 0.001) correlation between low AMU and being among the group of 17 herds still in business and investigated in 2018. There was a slight reduction of the mean E. coli herd ARI in the 2018-2019 study, with a change of the frequency distribution towards lower ARI values. This study provides evidence that AMU can be reduced in industrial meat rabbit breading without apparent impact on the overall production. A lowering of AMR at herd level seems occurring after 10 years AMU reduction.
Opleiding Informatica Is the Linux Completely Fair Scheduler Ready for Serverless Workloads?

Serverless computing changed the complexity of workloads on the underlying machines. Serverless workloads consist of thousands of short-running jobs, executed in either a container, or virtual machine, which was not done so extensively before. Previous research has shown that schedulers inﬂuence the performance of the workload. In this work, we introduce a novel benchmark, fc-microbenchmark , to evaluate the performance of the Linux scheduler on serverless workloads. The benchmark is built on top of AWS Firecracker, which manages microVMs for the Amazon Lambda platform. We use a Poisson arrival process to increase the realism of the benchmark. Using the benchmark, we compared the default Linux scheduler, called CFS, to other scheduling algorithms and policies available in the Linux kernel. We ﬁnd that CFS performs well on CPU-bound workloads, but is outperformed on workloads that introduce memory-intensive jobs. As such, we conclude that CFS needs further improvements to handle serverless workloads. We propose multiple pointers for further research, namely: dynamic selection of the scheduler depending on the type of the workload, the eﬀect of RR and FIFO on the preservation of locality and ﬁnally the time spent waiting by a process that is not preempted when scheduled by RR and FIFO.
Effects of vibration measurement error on remote sensing image restoration

Satellite vibrations would lead to image motion blur. Since the vibration isolators cannot fully suppress the influence of vibrations, image restoration methods are usually adopted, and the vibration characteristics of imaging system are usually required as algorithm inputs for better restoration results, making the vibration measurement error strongly connected to the final outcome. If the measurement error surpass a certain range, the restoration may not be implemented successfully. Therefore it is important to test the applicable scope of restoration algorithms and control the vibrations within the range, on the other hand, if the algorithm is robust, then the requirements for both vibration isolator and vibration detector can be lowered and thus less financial cost is needed. In this paper, vibration-induced degradation is first analyzed, based on which the effects of measurement error on image restoration are further analyzed. The vibration-induced degradation is simulated using high resolution satellite images and then the applicable working condition of typical restoration algorithms are tested with simulation experiments accordingly. The research carried out in this paper provides a valuable reference for future satellite design which plan to implement restoration algorithms.
Design and analysis of a 2-DOF RFM for the mirror sub-assembly (MSA) of ICF facility

This paper presents the design of a 2 degree-of-freedom (DOF) rotation flexure mechanism (RFM) that could be utilized as the pivot for the mirror sub-assembly (MSA) of transport mirrors in the target area of inertial confinement fusion (ICF) laser systems. The hybrid spring system is established as the analytical model of the 2-DOF RFM. With the suitable matrix in coordinate transformation, the overall compliance matrix is developed to reveal the compliance property of the mechanism and the compliance equations are obtained. The analytical results obtained from the compliance equations are validated by means of finite element analysis (FEA) with the accuracy of 1%. The compliance property and design tradeoffs of the 2-DOF RFM are discussed with the compliance equations. The 2-DOF RFM for the MSA of transport mirrors of ShenGuangIII (SGIII) facility is designed and optimized. Then, the MSA is modeled and analyzed by FEA. The analysis result shows that the 2-DOF RFM is feasible for the MSA design.
Research on Thermal Error Modeling and Prediction of Heavy CNC Machine Tools

Thermal error has been a significant factor influencing the accuracy of heavy CNC machine tools. A thermal experiment is performed on a typical heavy CNC machine tool. According to the temperature field of the machine tool, a new hierarchical clustering method is proposed to optimize temperature variables efficiently. Euler distance and correlation coefficient are both considered in the method, by which the collinearity of temperature variables is reduced. Thermal error prediction model is built based on optimized temperature variables utilizing MRA. Results show that the RMSE of thermal error prediction can be reduced to lower than 10 μ m, which has higher accuracy compared to other methods. This method is expected to be used in thermal error modeling and prediction of other heavy CNC machine tools.
Opleiding Informatica Analysis of extracted references to case law in Dutch court decisions

In the Dutch legal system, a judge may cite a previous judgment in his judgment for a great number of reasons. The citing of these previous judgments, sometimes referred to as jurisprudence or case law, is a common occurrence in judicial decisions. These judicial decisions are available in digital form on the website ‘ Rechtspraak.nl ’. A software framework to recognize and resolve the references to case law in these digital judicial decisions exists. The fruits of this framework can be seen on the website ‘ Linkeddata.overheid. nl ’. On here, one can view the processed judicial decisions along with the detected references marked in the text. A dump of the database behind the site has been made available to the public. The primary goal of this thesis is to analyse the extracted references in that database. Therefore, I will ﬁrst go over the framework itself and how it works. Subsequently, I will describe the characteristics of the judicial decisions that we are working with. Furthermore, I will be explaining the methods that I have used for the preprocessing, extraction and analysis of the data. Finally, I will extensively describe all types of errors I came across. I will be giving special attention to the type of error that occurs when a text is falsely detected as a reference; the false positives.
Opleiding Informatica CHAD-net: Continuous Human Action Detection in RGB video

In this paper, the problem of Human Action Detection (HAD) in live video feeds is studied. A novel architecture for Continuous Human Action Detection (CHAD) is introduced that diﬀers from traditional HAD algorithms, in that the CHAD-net is trained on sub-actions that make up larger actions. This enables the network to start detecting actions taking place before they have been completed, giving it an edge in Human-Robot Interaction (HRI) scenarios or when larger videos consisting of more than a single action are processed. The CHAD-net architecture uses ShuttleNet to detect sub-actions, and an Action Deducer (AD) to detect which action is taking place based on the detected sub-actions. This approach is evaluated on a HAD dataset (UCF101) and a specially selected subset C UCF101 that is more themed towards continuous human actions. Finally, experimental results show that state-of-the-art solutions for HAD outperform CHAD-net on the UCF101 dataset, but CHAD-net shows promising results on the C UCF101 dataset.
UNIFORM BOUND ON THE NUMBER OF PARTITIONS FOR 1 OPTIMAL CONFIGURATIONS OF THE OHTA-KAWASAKI 2 ENERGY IN 3 D ∗ 3

We study a 3D ternary system which combines an interface energy with a long range 5 interaction term. Several such systems were derived as a sharp-interface limit of the Nakazawa- 6 Ohta density functional theory of triblock copolymers. Both the binary case in 2D and 3D, and 7 the ternary case in 2D, are quite well understood, while very little is known about the ternary case 8 in 3D. In particular, it is even unclear whether minimizers are made of ﬁnitely many components. 9 In this paper we provide a positive answer to this, by proving that the number of components in 10 a minimizer is bounded from above by a computable quantity depending only on the total masses 11 and the interaction coeﬃcients. There are two key diﬃculties, namely the impossibility to decouple 12 the long range interaction from the perimeter term, and the absence of a quantitative isoperimetric 13 inequality with two mass constraints in 3D. Therefore, the actual shape of minimizers is unknown, 14 even for small masses, making the construction of suitable competing conﬁgurations signiﬁcantly 15 more delicate. 16
Steady-state performance of a grid-connected rooftop hybrid wind-photovoltaic power system with battery storage

Summary form only given, as follows. This paper reports the performance of a 4-kW grid-connected residential wind-photovoltic system (WPS) with battery storage located In Lowell, MA, USA. The system was originally designed to meet a typical New-England (TNE) load demand with a loss of power supply probability (LPSP) of one day in ten years as recommended by the utility company. The data used in the calculation was wind speed and irradiance of Logan Airport Boston (LAB) obtained from the National Climate Center In North Carolina. The present performance study is based on two-year operation (May 96-Apr 98) of the WPS. Unlike conventional generation, the wind and the sunrays are available at no cost and generate electricity pollution-free. Around noontime, the WPS satisfies its load and provides additional energy to the storage or to the grid. On-site energy production is undoubtedly accompanied with minimization of environmental pollution, reduction of losses in power systems transmission and distribution equipment, and supports the utility in demand side management (DSM). This paper includes discussion on system reliability, power quality, loss of supply, and effects of the randomness of the wind and the solar radiation on system design.
MTM at MediaEval 2014 Violence Detection Task

This paper describes the team MTM participation in Violent Scenes Detection (VSD) task of the MediaEval 2014 campaign. We propose an approach to the problem of detecting violence, which is based on probabilistic graphical models using Mel-frequency cepstral coefficients (MFCCs) as audio feature. In our approach, we employ Dynamic Bayesian Networks (DBNs) to represent a violent scene as an dynamic system.
A low-cost and very small wireless terminal integrated on the back of a flat panel array for 26 GHz band fixed wireless access systems

A compact wireless terminal (WT) with a high gain planar array has been developed for the Wireless IP Access System (WIPAS), which is a point-to-multipoint FWA (fixed wireless access) system in 26 GHz frequency band. Drastic cost reduction and downsizing are realized by using an alternating phase fed single layer waveguide array antenna and MMIC (microwave monolithic IC) technologies. This terminal is 190/spl times/190/spl times/55 mm/sup 3/ in volume and less than 2.0 kg in weight which accommodates over 31 dBi very high efficiency antenna with radome, RF module, IF modules, ASIC (application specific IC) for modem, TDMA (time division multiple access) equipment control, and MAC (medium. access control). Only an Ethernet cable with 24 DC power supply is attached on the terminal. This paper describes the design of WT with the focus upon the unique antenna and RF module.
High quality genome assembly of the anhydrobiotic midge provides insights on a single chromosome-based emergence of extreme desiccation tolerance

Abstract Non-biting midges (Chironomidae) are known to inhabit a wide range of environments, and certain species can tolerate extreme conditions, where the rest of insects cannot survive. In particular, the sleeping chironomid Polypedilum vanderplanki is known for the remarkable ability of its larvae to withstand almost complete desiccation by entering a state called anhydrobiosis. Chromosome numbers in chironomids are higher than in other dipterans and this extra genomic resource might facilitate rapid adaptation to novel environments. We used improved sequencing strategies to assemble a chromosome-level genome sequence for P. vanderplanki for deep comparative analysis of genomic location of genes associated with desiccation tolerance. Using whole genome-based cross-species and intra-species analysis, we provide evidence for the unique functional specialization of Chromosome 4 through extensive acquisition of novel genes. In contrast to other insect genomes, in the sleeping chironomid a uniquely high degree of subfunctionalization in paralogous anhydrobiosis genes occurs in this chromosome, as well as pseudogenization in a highly duplicated gene family. Our findings suggest that the Chromosome 4 in Polypedilum is a site of high genetic turnover, allowing it to act as a ‘sandbox’ for evolutionary experiments, thus facilitating the rapid adaptation of midges to harsh environments.
Comparison of Repair Index in Cigarette and Waterpipe Smokers: A Bio-Monitoring Assessment Using Human Exfoliated Buccal Mucosa Cells

Background: Repair index (RI) using DNA changes reveals the activity of carcinogenesis. Cigarette and waterpipe smoking are important contributors to oral cavity malignancy. The RI in cigarette and waterpipe smokers has not been compared so far. The aim of this study was to compare the RI in cigarette and waterpipe smokers using the human exfoliated buccal mucosa cells. Methods: The exfoliated buccal mucosa cells of 60 cigarette and waterpipe smokers and 20 nonsmokers were evaluated in a case-control study. The number of micronuclei (MN), broken egg (BE), karyorrhexis (KR), and karyolysis (KL) were counted in 1000 cells from randomly selected fields. The RI = (KL + KR)/(MN + BE) was calculated and compared between subjects and controls. Data were analyzed by one-way analysis of variance (ANOVA), Tukey's Honest Significant Difference (HSD), and Spearman's correlation coefficient test at P < 0.05 probability level. Results: The difference of MN (P < 0.0001), BE (P < 0.0001), KR (P < 0.0001), and KL (P < 0.0001) count was significant between cigarette smokers, waterpipe smokers, and nonsmokers. The RI was significantly different between groups (P = 0.007). The RI was significantly higher in cigarette smokers compared to waterpipe smokers (P = 0.04) and nonsmokers (P = 0.009). Conclusions: The RI was significantly higher in cigarette smokers compared to waterpipe smokers. The finding suggests that due to higher interrupted cellular hemostasis, the risk of carcinoma in waterpipe smokers can be greater than that in cigarette smokers.
Mycobacterium avium subsp. paratuberculosis and microbiome profile of patients in a referral gastrointestinal diseases centre in the Sudan

Mycobacterium avium subsp. paratuberculosis (MAP) causes Johne’s disease in animals with zoonotic potential; it has been linked to many chronic diseases in humans, especially gastrointestinal diseases (GID). MAP has been extensively studied in Europe and America, but little reports were published from Africa. Sudan is a unique country with close contact between humans and livestock. Despite such interaction, the one health concept is neglected in dealing with cases of humans with GID. In this study, patients admitted to the reference GID hospital in the Sudan over a period of 8 months were screened for presence of MAP in their faeces or colonic biopsies. A total of 86 patients were recruited for this study, but only 67 were screened for MAP, as 19 did not provide the necessary samples for analysis. Both real-time PCR and culture were used to detect MAP in the collected samples and the microbial diversity in patients´ faecal samples was investigated using 16S rDNA nanopore sequencing. In total, 27 (40.3%) patients were MAP positive: they were 15 males and 12 females, of ages between 21 and 80 years. Logistic regression analysis revealed no statistical significance for all tested variables in MAP positive patients (occupation, gender, contact with animal, milk consumption, chronic disease, etc.). A unique microbiome profile of MAP-positive patients in comparison to MAP-negative was found. These findings suggest that a considerable proportion of the population could be MAP infected or carriers. Therefore, increase awareness at community level is urgently needed to decrease the risk of MAP at human/animal interface. This study represents the first report of MAP in humans in the Sudan; nevertheless, a better view of the situation of MAP in humans in the country requires a larger study including patients with other conditions.
Individual and community-level factors associated with animal source food consumption among children aged 6-23 months in Ethiopia: Multilevel mixed effects logistic regression model

Background Diversified diet in childhood has irreplaceable role for optimal growth. However, multi-level factors related to low animal source food consumption among children were poorly understood in Ethiopia, where such evidences are needed for decision making. Objectives To investigate the magnitude and individual- and community-level predictors of animal source food (ASF) consumption among children aged 6–23 months in Ethiopia. Methods We utilized a cross-sectional pooled data from 2016/19 Ethiopia Demographic and Health Surveys. A stratified two-stage cluster design was employed to select households with survey weights were applied to account for complex sample design. We fitted mixed-effects logit regression models on 4,423 children nested within 645 clusters. The fixed effect models were fitted and expressed as adjusted odds ratio with their 95% confidence intervals and measures of variation were explained by intra-class correlation coefficients, median odds ratio and proportional change in variance. The deviance information criterion and Akaike information Criterion were used as model fitness criteria. Result in Ethiopia, only 22.7% (20.5%-23.9%) of children aged 6–23 months consumed ASF. Younger children aged 6–8 months (AOR = 3.1; 95%CI: 2.4–4.1), home delivered children (AOR = 1.8; 1.4–2.3), from low socioeconomic class (AOR = 2.43; 1.7–3.5); low educational level of mothers (AOR = 1.9; 95%CI: 1.48–2.45) and children from multiple risk pregnancy were significant predictors of low animal source consumption at individual level. While children from high community poverty level (AOR = 1.53; 1.2–1.95); rural residence (AOR = 2.2; 95%CI: 1.7–2.8) and pastoralist areas (AOR = 5.4; 3.4–8.5) significantly predict animal source food consumption at community level. About 38% of the variation of ASF consumption is explained by the combined predictors at the individual and community-level while 17.8% of the variation is attributed to differences between clusters. Conclusions This study illustrates that the current ASF consumption among children is poor and a multiple interacting individual- and community level factors determine ASF consumption. In designing and implementing nutritional interventions addressing diversified diet consumption shall give a due consideration and account for these potential predictors of ASF consumption.
