Gloss, Color, and Topography Scanning for Reproducing a Painting’s Appearance Using 3D Printing

High fidelity reproductions of paintings provide new opportunities to museums in preserving and providing access to cultural heritage. This article presents an integrated system that is able to capture and fabricate color, topography and gloss of a painting, of which gloss capturing forms the most important contribution. A 3D imaging system, utilizing stereo imaging combined with fringe projection, is extended to capture spatially varying gloss, based on the effect of specular reflectance polarization. The gloss is measured by sampling the specular reflection around Brewster’s angle, where these reflections are effectively polarized and can be separated from the unpolarized, diffuse reflectance. Off-center gloss measurements are calibrated relative to the center measurement. Off-specular gloss measurements, following from local variation of the surface normal, are masked based on the height map and corrected. Shadowed regions, caused by the 3D relief, are treated similarly. The area of a single capture is approximately 180 × 90 mm at a resolution of 25 × 25 µm. Aligned color, height, and gloss tiles are stitched together off-line, registering overlapping color regions. The resulting color, height, and gloss maps are inputs for the poly-jet 3D printer. Two paintings were reproduced to verify the effectiveness and efficiency of the proposed system. One painting was scanned four times, consecutively rotated by 90 degrees, to evaluate the influence of the scanning system geometric configuration on the gloss measurement. Experimental results show that the method is sufficiently fast for practical application, i.e., to scan a whole painting within eight hours, during closing hours of a museum. The results can well be used for the purpose of physical reproduction and other applications needing first-order estimates of the appearance (e.g., conservation diagnostics and condition reports). Our method to extend appearance scanning with gloss measurements is a valuable addition in the quest for realistic reproductions, in terms of its practical applicability—number of images needed for reconstruction and speed—and its perceptual added value, when added to color and topography reproduction.
Real-World Image Datasets for Federated Learning

Federated learning is a new machine learning paradigm which allows data parties to build machine learning models collaboratively while keeping their data secure and private. While research efforts on federated learning have been growing tremendously in the past two years, most existing works still depend on pre-existing public datasets and artificial partitions to simulate data federations due to the lack of high-quality labeled data generated from real-world edge applications. Consequently, advances on benchmark and model evaluations for federated learning have been lagging behind. In this paper, we introduce a real-world image dataset. The dataset contains more than 900 images generated from 26 street cameras and 7 object categories annotated with detailed bounding box. The data distribution is non-IID and unbalanced, reflecting the characteristic real-world federated learning scenarios. Based on this dataset, we implemented two mainstream object detection algorithms (YOLO and Faster R-CNN) and provided an extensive benchmark on model performance, efficiency, and communication in a federated learning setting. Both the dataset and algorithms are made publicly available.
Superhorizon effects on the gauge invariant effective energy density in 
f(R)
 gravity

In this article we study the gauge invariant effective energy momentum tensor for cosmological perturbations in f(R) gravity during the inflationary epoch. Considering the super-horizon regime, we derive the effective energy density up to the one-loop corrections. It describes the back-reaction effect of the fluctuations on the background space-time.
Leche materna: composición y factores condicionantes de la lactancia

INTRODUCCION En los ultimos anos se han destacado los beneficios inigualables para la madre y el nino que representa la alimentacion al pecho; aspectos biologicos, psicoafectivos, economicos y sociales. Sin embargo, muchos factores alentaron la disminucion de la lactancia materna, que marcaron uno de los cambios mas importantes en cuanto a la alimentacion de los bebes. Entre ellos, la administracion de otros liquidos azucarados en la mamadera, la gran difusion de formulas lacteas que acompanaron el crecimiento de la industria, la gran disponibilidad de biberones y tetinas, la introduccion temprana de otros alimentos y la incorporacion de la mujer al ambiente laboral, facilitaron este fenomeno. Actualmente la promocion de la lactancia ha tomado nuevo impulso. El reconocimiento creciente del valor incomparable de la leche humana en el desarrollo y maduracion del sistema nervioso central, en la proteccion inmunologica y de diferentes patologias en el nino otorga fundamentos mas que validos para recobrar la cultura del amamantamiento. El primer ano del nino constituye una de las etapas mas vulnerables de la vida con respecto a la nutricion. La lactancia es la alimentacion optima del recien nacido. Los ninos amamantados por madres sanas y bien nutridas pueden alimentarse exclusivamente al pecho durante los seis primeros meses.1,2 Ademas, cuando la lactancia ocurre a libre demanda, el bebe mantiene un equilibrio hidrico adecuado, aun en climas calidos, sin necesidad de ingerir otros liquidos para mitigar la sed.
Sensitivity Pattern Of Salmonella typhi And Paratyphi A Isolates To Chloramphenicol And Other Anti-Typhoid Drugs: An In Vitro Study

Purpose To investigate the antimicrobial sensitivity pattern of commonly prescribed antimicrobials (chloramphenicol, cefixime, ofloxacin, azithromycin, and ceftriaxone) against Salmonella enterica isolates. Methods Blood culture positive isolates of S. typhi and S. paratyphi A (N = 251) received at Metropolis Healthcare Limited (Mumbai, India) from four zones of India (North, South, West, and East) between April and August 2018 were tested for antimicrobial susceptibility by E-test method. Based on the minimum inhibitory concentration (MIC), the organism was categorized as sensitive, intermediate, and resistant against the respective antibiotics as per Clinical and Laboratory Standards Institute criteria 2018. Results Out of 251 Salmonella isolates, 192 (76.5%) were S. typhi and 59 (23.5%) were S. paratyphi A. All 251 (100%) Salmonella isolates were sensitive to cefixime, ceftriaxone, and azithromycin; 237/251 (94.4%) isolates to chloramphenicol and only 9/251 (3.6%) isolates were sensitive to ofloxacin. Based on average MIC and MIC breakpoints, Salmonella isolates were found to be sensitive to chloramphenicol (MIC: 3.89±6.94 µg/mL), cefixime (MIC: 0.13±0.11 µg/mL), azithromycin (MIC: 3.32±2.19 µg/mL), and ceftriaxone (MIC: 0.11±0.18 µg/mL) and resistant to ofloxacin (MIC: 2.95±6.06 µg/mL). More than 20% of Salmonella isolates had MICs of chloramphenicol as 1.5 µg/mL (27.85% isolates) and 2 µg/mL (29.53% isolates). Conclusion Our study confirms the re‑emergence of susceptibility of Salmonella isolates to chloramphenicol. Further, the concern about fluoroquinolone-decreased susceptibility as indicated by the intermediate susceptibility or resistance was reiterated in this study. Though cefixime, azithromycin, and ceftriaxone showed susceptibility, the possibility of antibiotic resistance with the irrational use of these antibiotics cannot be deterred. This study thus emphasizes the need for continuous evaluation and judicious use of antimicrobials, considering the ever-changing landscape.
Accelerated GPU Based Protein Sequence Alignment – An optimized database sequences approach

Smith-Waterman (S-W) algorithm is the perfect sequence alignment method for the biological database but practically this algorithm lacks pace due to high computational complexity. FASTA, BLAST and other heuristics approaches are faster in computations but less accurate. Volume and length variation of sequences require restructuring the database. Acceleration of Smith-Waterman algorithm on proper modern hardware brings perfection and accuracy. This paper presents a high-performance sequence alignment algorithm implemented on Kepler’s architecture graphic processor unit. This new implementation is improved version having reduced memory accesses to eliminate bandwidth congestion. The implementation is performed on Kepler’s architecture graphics processing unit on which the performance was raised to 51 Giga Cells updates per second GCPUS which is 138.3% increase than the previous implementation on GTX275 GPU. In this implementation protein database is converted into equal length sequence sets on advanced GPU. By this workload is distributed among GPU microprocessor threads. This results in improved implementation than previous implementations.
Effect of humidiy on long fatigue life more than 107 cycles in high strength steel

Long-term fatigue tests have been conducted in order to clarify the effect of humidity on the fracture mechanism in long life region more than 10 7 cycles. The material used was a low alloy steel, JIS SNCM439 (AISI4340). Tests were performed using cantilever-type rotating bending fatigue testing machines operating at a frequency of 3150rpm in laboratory air and in dry air. The dew point of dry air was – 60°C In laboratory air, fatigue failure occurred at stress levels below the conventional fatigue limit, leading to a step-wise S-N curve. Also in dry air, the similar step-wise S-N curve was obtained, but the position of the horizontal line in the S-N curve shifted to high stress level i.e. short life region. Fracture mode at stress levels below the horizontal line was fish-eye type in both environments, i.e. cracks were initiated from a nonmetallic inclusion at subsurface. Since two different fracture modes, i. surface slip type and fish-eye type, coexisted, fatigue life distribution was scattered at the stress level of the horizontal line. Therefore, it is concluded that the appearance of horizontal line was due to the scatter of fatigue life corresponding to the fracture mode.
Access Point Reconfiguration Using OpenWrt

The research project Mobile mEsh Network to Aid in CountEring drug TRAffiCKing (M.E.N.A.C.E-TRACK) proposes the creation of a dynamic mesh network, intended to interconnect field personnel to a base of operations whenever possible. This type of network accepts the dynamic disconnection and reconnection of nodes. To configure a mesh node using, for instance, an access point, usually a modified firmware is needed. In this paper we present the first steps to build the M.E. N.A. C.E-TRACK infrastructure concerning the configuration of the access point, the chosen firmware and some configuration scenarios on an infrastructured network in order to demonstrate its flexibility.
X-Armed Bandits: Optimizing Quantiles, CVaR and Other Risks.

We propose and analyze StoROO, an algorithm for risk optimization on stochastic black-box functions derived from StoOO. Motivated by risk-averse decision making fields like agriculture, medicine, biology or finance, we do not focus on the mean payoff but on generic functionals of the return distribution. We provide a generic regret analysis of StoROO and illustrate its applicability with two examples: the optimization of quantiles and CVaR. Inspired by the bandit literature and black-box mean optimizers, StoROO relies on the possibility to construct confidence intervals for the targeted functional based on random-size samples. We detail their construction in the case of quantiles, providing tight bounds based on Kullback-Leibler divergence. We finally present numerical experiments that show a dramatic impact of tight bounds for the optimization of quantiles and CVaR.
A Survey on Linking of Cell Tracks Using Segmentation

In maximum of image process algorithms Segmentation is a key technique. It splits a digital image into several regions so as to examine them. Once segmentation is done, linking of frames is additionally a very important task. It is additionally accustomed distinguish completely different objects within the image. Several image segmentation techniques are developed by the researchers so as to form pictures swish and simple to judge. It is troublesome to process parallel algorithms in serial processors. This paper presents a literature review of basic image segmentation techniques, linking algorithms and want to process in hardware tools.

Doubly Salient Synchronous Generator for Gas Turbine Engines

A novel generator topology with stationary field windings is proposed for use as a synchronous generator. The generator is initially intended to be directly mounted to the power turbine shaft of an aviation-class gas turbine engine. This topology also has several attributes which make it well suited to be “embedded” (integrated within) aircraft, land or sea based gas turbines onto the high or low pressure rotor shafts. In the initial application, the combination of the generator and engine forms a very compact, portable power source for applications that require power in the range of 150-300kW. A mathematical model of the machine is presented. Predicted performance is then compared to experimental results from a proof-of-concept prototype machine.
A Study on the Influence of Self-concept and Social Support on Occupational Choice Intention

As enterprises have raised the requirements on the educational background and professional degree of job seekers, new graduates are facing raised employment requirements and ever increasing competitors, while whether their academic performance can meet the requirements of enterprises is no longer determined by their workplace competitiveness after the graduation. Rather, they need to develop a concrete understanding of cultivating professional competence, actively enrich their professional competence during school, enhance their self-concept through interactions with families, friends, teachers, and peers, and acquire the required academic performance to establish their future career options. The main purpose of this study is to investigate the corelation among colege students’ self-concept, social support, academic performance, and occupational choice intention. The research framework was established based on literature review and the correlation among research variables. This study conducted a questionnaire survey on college students in Taiwan, and retrieved 1,406 effective samples. The data were analyzed with statistical analysis using Amos. Linear structural equation models and multi-group analysis were also used for analysis. Analysis on the factors of self-concept and their differences found that, the importance level of relationship with parents was rated the highest by the students. Analysis on the factors of social supports and their differences showed that, relationship with peers has the highest rating. Moreover, social support has a positive and direct effect on academic performance. Self-concept has positive and direct effects on occupational choice intention. Self-concept and social support have significant effects on occupational choice intention through the mediating effect of academic performance. The multi-group analysis showed that academic performance
Quantity Measurement and Balanced Growth in Multi–Sector Growth Models∗

Multi–sector models typically rely on a numeraire to aggregate quantities whereas NIPA uses the chain index. For three popular versions of the multi–sector growth model, we provide analytical expressions for the growth of aggregate quantities under both measurement methods and establish that the compound differences are sizeable over long horizons. We show that using the chain index captures more accurately the aggregate effects of secular changes in relative prices. For example, in a standard model of structural transformation, measuring GDP growth with the chain index captures that Baumol’s disease reduces welfare growth, which using a numeraire misses.
The Effectiveness of Inspiratory Muscle Training in Weaning Critically Ill Patients from Mechanical Ventilation

BACKGROUND: Inspiratory muscle weakness is a consequence of mechanical ventilation that contributes to weaning failure in critical ill patients. Since 1980, case reports of inspiratory muscle training (IMT) in ventilated, difficult to be weaned patients have proposed that this training strategy is associated with successful weaning. OBJECTIVE: We evaluated the efficacy of the inspiratory muscle training on the weaning process. METHODS: We conducted a literature search in the following databases: PubMed, EMBASE, Scopus and Google scholar. Selected keywords included inspiratory/ respiratory muscle training, weaning/failure, mechanical ventilation, critically ill, threshold load, intubated/ tracheostomy. RESULTS: In our analysis we included three randomized control trials involving 150 patients. The studies used different devices of training and training protocols. Inspiratory muscle training significantly increased inspiratory muscle strength in relation to sham or no training. CONCLUSION: Although IMT leads to significant increase of respiratory muscle strength, it has not yet been clearly demonstrated that this also leads to successful weaning. Further large randomized studies are needed to determine the beneficial effect of IMT in weaning patients from ventilatory support.
An Efficient Routing Protocol design and Optimizing Sensor Coverage Area in Wireless Sensor Networks

Wireless sensor networks (WSN) represent a new paradigm shift in ad-hoc networks. Wireless Sensor Networks consists of small nodes with sensing, computation and communication capabilities. The sensor networks task is to sense the environment, and relay the information back to a remote base station using multi-hop infrastructure less architecture, where the user can access it. Also since power awareness is an essential design issue in designing a routing protocol for Wireless Sensor Networks, a novel hierarchical based clustering protocol called Efficient Routing Protocol (ERP) for data gathering and aggregation is also proposed for long-lived sensor networks. This proposed protocol handles the redundancy of data problem by using a proper routing tree construction method, thus, ensuring that only effective data is being transmitted through the network. Also it ensures good performance in terms of lifetime by minimizing power consumption for in-network communications and balancing the power load among all the nodes.
Comparing the Osteogenic Potentials and Bone Regeneration Capacities of Bone Marrow and Dental Pulp Mesenchymal Stem Cells in a Rabbit Calvarial Bone Defect Model

The bone regeneration efficiency of bone marrow mesenchymal stem cells (BMSCs) and dental pulp mesenchymal stem cells (DPSCs) combined with xenografts in the craniofacial region remains unclear. Accordingly, this study commenced by comparing the cell morphology, cell proliferation, trilineage differentiation, mineral synthesis, and osteogenic gene expression of BMSCs and DPSCs in vitro. Four experimental groups (empty control, Bio-Oss only, Bio-Oss+BMSCs, and Bio-Oss+DPSCs) were then designed and implanted in rabbit calvarial defects. The BMSCs and DPSCs showed a similar morphology, proliferative ability, surface marker profile, and trilineage-differentiation potential in vitro. However, the BMSCs exhibited a higher mineral deposition and expression levels of osteogenic marker genes, including alkaline phosphatase (ALP), runt related transcription factor 2 (RUNX2), and osteocalcin (OCN). In the in vivo studies, the bone volume density in both MSC groups was significantly greater than that in the empty control or Bio-Oss only group. Moreover, the new bone formation and Collagen I / osteoprotegerin protein expressions of the scaffold+MSC groups were higher than those of the Bio-Oss only group. Finally, the Bio-Oss+BMSC and Bio-Oss+DPSC groups had a similar bone mineral density, new bone formation, and osteogenesis-related protein expression. Overall, the DPSCs seeded on Bio-Oss matched the bone regeneration efficacy of BMSCs in vivo and hence appear to be a promising strategy for craniofacial defect repair in future clinical applications.
