INVESTIGATING PECTORAL SHAPES AND LOCOMOTIVE STRATEGIES FOR CONCEPTUAL DESIGNING BIO-INSPIRED ROBOTIC FISH

This paper describes the performance analysis of a conceptual bio-inspired robotic fish design, which is based on the morphology similar to the boxfish (Ostracion melagris). The robotic fish prototype is driven by three micro servos; two on the pectoral fins, and one on the caudal fin. Two electronic rapid prototyping boards were employed; one for the movement of robotic fish, and one for the force sensors measurements. The robotic fish were built using fused deposition modeling (FDM), more popularly known as the 3D printing method. Several designs of pectoral fins (rectangular, triangular and quarter-ellipse) with unchanging the value of aspect ratio (AR) employed to measure the performance of the prototype robotic fish in terms of hydrodynamics, thrust and maneuvering characteristics. The analysis of the unmanned robotic system performance is made experimentally and the results show that the proposed bioinspired robotic prototype opens up the possibility of design optimization research for future work.
Selecting key traits to indicrectly assess common bean growth under water stress

Recognize water stress constraints on common bean growth may help to select tolerant genotypes, manage irrigation based on plant necessity and predict losses. This manuscript aims to select key traits that discriminate magnitudes of water stress on common bean and indicates plant growth constrains. To do so, an experiment was set in a greenhouse with two factors: crop evapotranspiration replenishment and cultivars. First factor was comprised of 25, 50, 75, 100, 125 and 150% of crop evapotranspiration replenishment starting at flowering (32 days after germination). The second factor was composed of the cultivars BRS Estilo and IPR Campos Gerais. A randomized block scheme with five replications was used, totalizing 60 experimental units. On the 55 th day after germination, we analysed morphological (steam diameter, leaf area, and number of trifoliolates) and physiological (net assimilation of CO 2 , stomatal conductance, leaf transpiration, and total content of chlorophyll) traits. A multivariate analysis of variance indicated a single effect of crop evapotranspiration replenishment. Thus, a canonical discriminant analysis was applied and the discrimination was confirmed by the Scott-Knott hierarchical clustering. We harvested the plants to correlate the selected traits with the aerial dry weight to determine its ability to assess plant growth indirectly. The traits related to leaf gas exchanges were the strongest discriminators of levels of water stress and showed a moderated correlation with common bean growth. For instance, by assessing the net assimilation of CO 2 throughout the most stressful periods of the day, such a response variable turned out to be the most promising trait to be used in order to singly integrate both objectives under scrutiny.
Deep Learning in Medical Imaging: A Review

Computer vision and machine learning techniques have usually found their way into medical image analysis as there are strong synergies between the two ﬁelds. Medical imaging professionals typically draw inspiration from computer vision techniques to register images from multiple modalities, segment the regions of interest (ROI) and measure ROIs to streamline the analysis pipeline, and from machine learning techniques to build models that are capable of integral tasks such as anomaly detection, progression tracking and recognition. Historically, we have seen fast adaptation of computer vision techniques and with the recent signiﬁcant improvements demonstrated by the use of deep learning techniques in other ﬁelds, we believe that the medical imaging professional can beneﬁt from it as well. Deep learning is a collection of techniques that consists of new as well as old algorithms from the neural networks community. Ideas such as convolutional neural networks and autoencoders go back to the 1980s and 1990s, while concepts such as deep belief networks and long short term memory in recurrent neural networks are relatively new. Since its advent, deep learning has been mostly perceived as a black-box and its adaptation to medical imaging has been relatively slow. In this report, we attempt to untangle the techniques collectively known as deep learning and present their building blocks concisely. We also present a comprehensive review of the state-of-the-art applications of deep learning techniques in medical imaging. It is our belief that we can inspire more medical professionals to adapt deep learning techniques to their analysis pipeline and further reﬁne the techniques that have surfaced so far.
Scalar Pair Production In Near Extremal Charged Black Holes

We review the spontaneous pair production of charged scalar particles in the near horizon region of near extremal charged black holes. The pair production rate is analytically computed and its thermal interpretation is discussed. Moreover, the associated holographical correspondence has been checked at the 2-point function level by comparing the absorption cross section ratio as well as the pair production rate both from the gravity and the conformal field theories (CFTs) sides.
Equivalent Permeability Distribution for Fractured Porous Rocks: Correlating Fracture Aperture and Length

Estimating equivalent permeability at grid block scale of numerical models is a critical issue for large-scale fractured porous rocks. However, it is difficult to constrain the permeability distributions for equivalent fracture models as these are strongly influenced by complex fracture properties. This study quantitatively investigated equivalent permeability distributions for fractured porous rocks, considering the impact of the correlated fracture aperture and length model. Two-dimensional discrete fracture models are generated with varied correlation exponent ranges from 0.5 to 1, which indicates different geomechanical properties of fractured porous rock. The equivalent fracture models are built by the multiple boundary upscaling method. Results indicate that the spatial distribution of equivalent permeability varied with the correlation exponent. When the minimum fracture length and the number of fractures increase, the process that the diagonal equivalent permeability tensor components change from a power law like to a lognormal like and to a normal-like distribution slows down as the correlation exponent increases. The average dimensionless equivalent permeability for the equivalent fracture models is well described by an exponential relationship with the correlation exponent. A power law model is built between the equivalent permeability of equivalent fracture models and fracture density of discrete fracture models for the correlated aperture-length models. The results demonstrate that both the fracture density and length-aperture model influence the equivalent permeability of equivalent fracture models interactively.

Shaping Robot Gestures: The Effect of Amplitude, Speed on Users’ Perception

This study investigates the interplay between the way a robot displays different gestures with changes in amplitude and speed and the way these gestures are perceived by the users. The results with 30 participants show that, at least in some cases, there is an association between the speed and amplitude of a gesture—two parameters that account for energy and spatial extension—and the scores on the Godspeed questionnaire. It shows that the Godspeed scores tend to be different for different values of amplitude and speed. The main implication of such an observation is that, for a social robot, it is not sufficient to decide what gestures a robot should display during an interaction, but also how the gestures are performed in order to make them self-explainable.
Use of stream mouth habitats by Cottus perifretum and Leuciscus cephalus along the River Meuse (the Netherlands)

Abstract. Size-frequency data were collected for two rheophilic fish species, Cottus perifretum and Leuciscus cephalus, at the confluences of 18 lowland tributaries along the regulated River Meuse (the Netherlands) between May 2004 and April 2005. Cottus perifretum is a resident species, using these stream mouth habitats throughout its entire life: i.e. as a spawning, nursery and adult habitat. Leuciscus cephalus is a transient species that uses these stream mouth habitats only as a temporary 0+ juvenile habitat during fall and early winter. This study suggests that the stream mouth habitats along the River Meuse fulfil different ecological functions for C. perifretum and L. cephalus.
Crop rotations compared with continuous canola and wheat for crop production and fertilizer use over 6 yr

Abstract: Local economic, logistic, soil, and weather conditions have made appropriate rotations vary from one area to another. Seed yield and fertilizer use in rotations were compared with continuous cropping for 6 yr in the southeast Peace region of Alberta, Canada. Canola (C) (Brassica napus L.), wheat (W) (Triticum aestivum L.), pea (P) (Pisum sativum L.), barley (B) (Hordeum vulgare L.), and flax (F) (Linum usitatissimum L.) were grown in 12 treatments [i.e., continuous canola (CC) and wheat (WW) and rotations of W–C, P–W–W, C–W–W, C–C–W, P–C–W, C–P–W, W–B–C, B–W–C, F–W–C, and F–C–W]. Canola yield increased with 1 or 2 yr breaks from canola. Within rotations, there was a trend to lower canola yield on canola stubble compared with other crop stubbles. Wheat yield was generally lower in WW than in rotations. Among rotations, wheat yield tended to be greater on pea stubble compared with canola, wheat, barley, and flax stubbles. Averaged over 2010–2015, the canola yield benefit from rotations was 0.632 Mg ha-1 (19.4%) over CC and the wheat yield benefit from rotations was 0.313 Mg ha-1 (7.2%) over WW. Nitrogen saving was observed when pea was included in rotation.
Reproductive behavior and development in Spilotes sulphureus (Serpentes: Colubridae) from Ecuador

Reproductive behavior and development in Spilotes sulphureus (Serpentes: Colubridae) from Ecuador. The Birdsnake Spilotes sulphureus is a large-sized species that occurs from the Amazon region to the Atlantic forest of South America. Despite the wide distribution little is known about its natural history. Here we report, for the frst time, reproductive behavior displayed by this species observed in a pair of Ecuadorian specimens in captivity. A ritualized pre-copulatory behavior followed a colubrine pattern similar to the congeneric species Spilotes pullatus. The repertoire included chin-rubbing, continuous tongue ficking, head raising, body jerking, cloacal gaping, and partial mounting. Oviposition occurred 86–98 days after of the frst copulation. Females lay clutches of 7–14 eggs. Juvenile coloration is remarkably different from adults. Newborns have a dorsum with transverse brown or gray bands, and white or pale gray interspaces; young of 1–2 years have green bands and yellow-green interspaces; adults have dark green bands. Ontogenetic color changes are presumably associated with antipredator strategies, change in size, vulnerability or habitat and microhabitat selection.
A Thermal Study on Joule-Heating Induced Effects in Dielectrophoretic Microfilters

Dielectrophoretic filters are used for separation and detection of cells or microorganisms suspended in liquid media and are based on particles migration in non-uniform electric field provided by microfabricated electrodes. In this paper, thermal effects induced by Joule heating on flow profile and particles distribution by mean of parameter variation with temperature are investigated. The equation system with boundary condition for solving physical quantities such as electric field is described by taking into account the temperature gradient. The models are applied to a microfilter with planar castellated electrodes placed on a channel separation, and numerically solved with simulation software packages. The analyses were made for various set of parameters (as applied voltage and particles size). The results are discussed and compared in terms of temperature influence on electric field, dielectroforetic force, flow profile and spatial concentration distribution of particles inside the separation microchannel.
New classes of solutions of an alternative Cauchy equation

In this paper we consider the alternative Cauchy equation g(x + y) 6= g(x)g(y) implies f(x + y) = f(x)f(y) where f, g are unknown functions from R into a group (S, · ). Assuming a slightly different hypothesis than in [1] we describe new classes of solutions.
Jurkat T Cell Detectability and Toxicity Evaluation of Low-Temperature Synthesized Cadmium Quantum Dots

Early and highly accurate detection of diverse diseases is in urgent demand than ever, especially for cancers and infectious ones. Among possibilities, biosensing by utilizing conjugated nanoparticles is still a method of choice. However, the toxicity of quantum dots remains a big matter of concern in those biooriented applications. In this study, mercaptosuccinic acid-coated cadmium selenide quantum dots of approximately 2.3 nm were synthesized with a simple green method at low temperature and cost-saving chemicals. The influence of synthesis factors was investigated with different spectroscopic methods. The toxicity issue was evaluated on the NIH-3T3 cell line (ATCC® CRL-1658™) and an MTT assay, revealing a secure threshold of 20 μg/ml. Consequently, successful conjugation to the CD3 antibody including an A/G protein bridge was implemented and verified with fluorescent methods. Finally, Jurkat T cell detectability of conjugated CdSe was successfully validated with fluorescent microscopy. The CdSe-based products are accessible for future biosensing applications.
A STATISTICAL ANALYSIS FOR THE CAR KEY FOB CROWDSOURCED DESIGN EVALUATION RESULTS BASED ON THE CDESIGN FRAMEWORK

The “power of the crowd” has been repeatedly demonstrated and various Internet platforms have been used to applied collaborative intelligence to areas that range from open innovation to conceptual design. However, crowdsourcing applications in the fields of design research and creative innovation have been much slower to emerge. In this paper, the statistical analysis methods (i.e., normal probability plots) were used to validate the crowdsourced design evaluation results in the authors’ previous crowdsourced design case study (i.e., car key fob design task). The discussion about the ranking distributions and results suggested that standard distribution trendlines and r2 results proved the effects of the ranking evaluation method used in the case study. The distribution determined that the evaluation process and results matched a normal distribution. As the contribution to knowledge, this paper applied the statistical analysis method to measure and approve the crowdsourced design evaluation method and its results.
Transmitter Components for THz Applications and a Simple Setup for THz Spectroscopy

During the last two decades, fast pulsed lasers with pulse durations below 1000 fs have prepared the ground for the generation of short electromagnetic pulses. In such femtosecond laser systems a pulse duration of 1000 fs corresponds to a frequency of f = 1THz (10 Hz), that is unattainable with typical electrical microwave circuits. From an optics point of view, THz radiation with wavelengths between 1mm and 100μm is often called “far infrared”. Not only this term indicates that in optics THz radiation was for a long period out of scope. Hence THz technology is a relatively new and challenging field in research.
Sympatry among Three Suid Species (Family Suidae) on the North Coast of Kenya

ABSTRACT Three species of suids occur on the broad coastal plain of Kenya east and north of the Tana River; desert warthog Phacochoerus aethiopicus, common warthog Phacochoerus africanus, and bushpig Potamochoerus larvatus. Systematic cameratrap surveys, comprising 9229 camera-trap days on grids at six study sites, were used to determine the distribution and relative abundance of these three suids in the Boni-Dodori Forest Complex (ca. 4000 km2) and in Arabuko-Sokoke Forest Reserve (416 km2) on Kenya's north and central coasts, respectively. In the Boni-Dodori Forest Complex, desert warthog was captured at one camera site, common warthog at four camera sites, and bushpig at 33 camera sites. In Arabuko-Sokoke Forest Reserve, only bushpig was captured (seven camera sites). Sympatry of desert warthog and common warthog seems limited in the Boni-Dodori Forest Complex. Here, desert warthog appears to be narrowly sympatric with bushpig whereas common warthog is broadly sympatric with bushpig. Sympatry of the three suids in this region was not previously reported. This sympatry is absent in Arabuko-Sokoke Forest Reserve.
Correlates, predictors, reference ranges and agreement between percent body fat measured using bioelectric impedance analysis and skinfold-thickness measurements in young nigerian adults

Background: Establishment of population specific normative databases for body composition is important in determining clinically useful cut-points for definition of excessive body fat or obesity for preventive or treatment programmes. This study provides the correlates, predictors, reference ranges and agreement between Percent Body Fat (PBF) measured using Bioelectric Impedance Analysis (BIA) and SkinfoldThickness Measurements (STM) in young Nigerian adults. Materials and Methods: A total of 531 apparently healthy individuals who were within ages 18 and 30 years were consecutively recruited in this study. BIA and STM (from three anatomical sites) were used to estimate PBF while anthropometric parameters were assessed following standard procedures. PBF computation was based on standard formulae. Socio-demographic characteristics were obtained using a proforma. Data were analysed using descriptive and inferential statistics at 0.05 alpha level. Results: There was significant difference in PBF measured by BIA and STM (20.69±9.97 vs. 13.4±9.37; t=12.28, p=0.001). There was significant correlation between PBF assessed by BIA and STM (r=0.912; p=0.001). The socio-demographic and anthropometric variables were significantly correlated with PBF (p <0.05) measured by BIA and STM respectively. The variability of the predictive of models for PBF from age, weight and height was 34.0% (R2 =34.0) and 50.9% (R2 =50.9) for males and females using BIA, while, the variability for PBF assessed using STM was 49.1. 0% (R2 =49.1) and 40.4% (R2 =40.4) for males and females. Conclusion: This study provides reference values for PBF using BIA and STM in young Nigerian adults. BIA method compared with STM overestimated PBF, although these two methods correlates strongly in the acceptable and moderately overweight range and not among the lean and obese participants. Age, gender and anthropometric factors were significantly determinants of the PBF. Age, height and weight seems to be moderate predictors of PBF but not without significant errors.
A Mechanistic Study on the Non-genotoxic Carcinogenicity of the Food Contaminant Semicarbazide

Semicarbazide was brought to the forefront of scientific discussions by the scientific community in the early 2000’s as the substance was discovered in several food products from both synthetic and natural sources. Although semicarbazide was processed through several toxicological assays and classified as a non-genotoxic carcinogen, underwhelming amounts of toxicological data exists for the compound. The present study is one of the first in-vitro studies to examine the relationship between sub-pathophysiological concentrations of reactive oxygen species and the anomalous non-genotoxic carcinogenicity induced by semicarbazide through the upregulation of intracellular signalling pathways. A novel finding of the present study was where NRK cells were exposed to micromolar concentrations of semicarbazide, an inverse relationship between protein kinase C activity, and free radical concentration proportionally increases > 2-fold. It is the hypothesis of the present study that the >2-fold increase in free radical concentration and upregulation of protein kinase C from the 0.01mM treatment of semicarbazide has the capacity to alter physiological signaling mechanisms into a subpathophysiological state. These changes in the cellular environment could be the initiation mechanism that facilitates the manifestation of cancer in a cell population. The induced upregulation of protein kinase C activity within NRK cells by semicarbazide can be extrapolated to downstream mediators of the Ca2+ dependent signaling pathway and the mitogen activated protein kinase signaling pathway. The hypothesis of the present study concludes by highlighting the importance of these pathways in the manifestation of semicarbazide induced non-genotoxic carcinogenicity. In conclusion, this study classifies semicarbazide as an intracellular signaling mitogen based on its capacity to modulate protein kinase C activity and the concentrations of intracellular reactive oxygen species.
ChaLearn Looking at People 2015: Apparent Age and Cultural Event Recognition datasets and results

Following previous series on Looking at People (LAP) competitions [14, 13, 11, 12, 2], in 2015 ChaLearn ran two new competitions within the ﬁeld of Looking at People: (1) age estimation, and (2) cultural event recognition, both in still images. We developed a crowd-sourcing application to collect and label data about the apparent age of people (as opposed to the real age). In terms of cultural event recognition, one hundred categories had to be recognized. These tasks involved scene understanding and human body analysis. This paper summarizes both challenges and data, as well as the results achieved by the participants of the competition. Details of the ChaLearn LAP competitions can be found at http://gesture.chalearn. org/.
Simulating ‘‘Soft’’ Electronic Devices

A combination of classical molecular dynamics simulations and very large scale semiempirical molecular orbital calculations has been used to simulate field-effect transistors in which both the dielectric layer and the semiconductor are incorporated in a self-assembled monolayer of suitable functionalized alkylphosphonic acids. In such simulations, both the dynamics of the flexible organic molecules and the electronic properties of the molecular aggregates must be taken into account. First steps towards realistic simulations of such devices are described.

The aim of the paper is the application of evolutionary non-stationary random vibration theory in the classic statistical solution vibrations. The dynamic model parameters are the deterministic function. The evolutionary non-stationary random function will be modelled by changeable speed of the vehicle model and vertical irregularity of track. It’ll assume evolutionary Gaussian process.
