A New Electronic Instrumentation Approach for the Acquisition of Microscopic Blood Smear Images for the Automatic Diagnosis of Anemia

Anemia is a blood abnormality that affects the quantity and quality of red blood cells in the human body. This sometimes banal sign spares no continent and no social stratum. This anomaly is generally appreciated through biological analyzes of patients’ blood. These analyzes, which boil down to the knowledge of hemato-metric constants, cannot by themselves allow the characterization of certain forms of anemia in the sense that most anemia are related to the morphology and color of red blood cells. Our work in this paper is to perform blood smears on patients and perform a morphological and colorimetric analysis of red blood cells on these smears. This approach allowed us to highlight on each erythrocyte morphological and colorimetric descriptors to accurately identify the types of anemia by image processing methods. This identification is performed in an automated environment to allow pathologists to respond quickly to anemia-related emergencies and also improve the treatment to be conducted. This automation required the implementation of a new approach to electronic instrumentation and the acquisition of microscopic blood smear images for the automatic and rapid diagnosis of anemia.
Monitoring citrus thrips, Scirtothrips aurantii Faure (Thysanoptera, Thripidae), with yellow card traps and the effect of latitude on treatment thresholds

Comparisons between fluorescent “Saturn Yellow” traps on the shady, southern side of the tree and non‐fluorescent yellow card traps on the sunny, northern side of the tree were conducted on orange trees at different latitudes in South Africa. The smaller card traps caught significantly more (P < 0.01) citrus thrips than the Saturn Yellow traps at all latitudes south of 24 ° S and this difference between trap types increased with latitude. Treatment thresholds for the card traps were estimated from regression equations relating the two different trap types by substituting previously established treatment thresholds for the Saturn Yellow traps. These card trap treatment threshold estimates were directly proportional to latitude (r2 = 0.98). The threshold estimates for the southernmost latitude (33 °S) were verified at nine orchards using yellow polyvinyl chloride card traps.
A new pinched nonlinear hysteretic structural model for automated creation of digital clones in structural health monitoring

Optimizing risk treatment of structures in post-event decision-making is extremely difficult due to the lack of information on building damage/status after an event, particularly for nonlinear structures. This work develops an automated, no human intervention, modeling approach using structural health monitoring results to create accurate digital building clones of nonlinear structures for collapse prediction assessment and optimized decision-making. Model-free hysteresis loop analysis structural health monitoring method provides accurate structural health monitoring results from which model parameters of a nonlinear computational foundation model are identified. A new identifiable nonlinear smooth hysteretic model capturing essential structural dynamics and deterioration is developed to ensure robust parameter identification using support vector machines. Method performance is validated against both numerical and experimental data of a scaled 12-story reinforced concrete nonlinear structure. Results of numerical validation show an average error of 1.5% across 18 structural parameters from hysteresis loop analysis and an average error of 2.0% over 30 identified model parameters from support vector machines in the presence of 10% added root-mean-square noise. Validation using experimental data of the scale test reinforced concrete structure also shows a good match of identified hysteresis loop analysis and predicted nonlinear stiffness changes using the digital clones created with an average difference of 1.4%. More importantly, the predicted response using the digital clones for the highly nonlinear pinched hysteretic behavior matches the measured response well, with the average correlation coefficient Rcoeff = 0.92 and average root-mean-square error of 4.6% across all cases. The overall approach takes structural health monitoring from a tool providing retrospective damage data into automated prospective prediction analysis by “cloning” the structure using computational modeling, which in turn allows optimized decision-making using existing risk analyses and tools.
Crossed induction of sex in sympatric congeneric rotifer populations

The transition from asexual to sexual reproduction in rotifers of the genus Brachionus (Monogononta) is triggered by a chemical signal produced and released by the rotifers themselves; the signal accumulates in the environment as population density increases. The response to this signal has been hypothesized to be speciesspecific. If not, the timing of sex and final diapausing egg production of a species might not be optimized. In this study, a set of experiments—based on individual and mass culture approaches—was carried out to investigate the differentiation in sex induction signals between sympatric and allopatric congeneric Brachionus populations by analyzing the capability of the medium conditioned by the growth of a population (i.e., medium containing the inducing signal) to induce sex in a different one. We found that populations induce sex in response to medium conditioned by congeneric populations. Results suggest differences among species in their production and responsiveness to sex‐inducing signals, as well as slight differentiation in these signals. The observed lack of strong differentiation between sympatric populations is proposed to have implications in avoidance of competition.
Phylogenetic Analyses using Molecular Markers Reveal Ecological Lineages in Medetera (Diptera: Dolichopodidae)

Abstract Medetera Fischer von Waldheim is the most speciose genus in the Medeterinae, with a nearly ubiquitous global distribution. Phylogenetic relationships within Medetera and between Medetera and four other medeterine genera were investigated using mitochondrial (COI, 16S) and nuclear (18S) markers to test morphological hypotheses. Our results confirm most of Bickel's hypotheses. Thrypticus Gerstäcker shows a sister-group relationship with Medetera + Dolichophorus Lichtwardt. The Medetera species included here split into two clades. One clade corresponds to the M. diadema L. — veles Loew species group sensu Bickel. The second clade is largely composed of the M. apicalis (Zetterstedt) species group sensu Bickel and the M. aberrans Wheeler species group sensu Bickel + Dolichophorus. Although most Medeterinae are associated with plants (mainly trees), species in at least two separate lineages demonstrate a secondary return to terrestrial habitats. The implication of this evolutionary phenomenon is briefly discussed.
An integrated intrusion detection system using correlation‐based attribute selection and artificial neural network

Serious concerns regarding vulnerability and security have been raised as a result of the constant growth of computer networks. Intrusion detection systems (IDS) have been adopted by network administrators to provide essential network security. Commercial IDS in the market do not have the capability to identify novel attacks but generate false alarms for legitimate user activities. Neural networks can be applied for the solution of these issues and for providing improved accuracy. Correlation‐based attribute selection ranks the features according to the highest correlation between the attributes and class label. In this article, the authors propose a correlation‐based feature selection integrated with neural network for identifying anomalies. Experimental analysis performed on NSL‐KDD and UNSW‐NB datasets, which are benchmark datasets of intrusion detection with current attacks. The results show that the proposed model is superior in terms of accuracy, sensitivity, and specificity in comparison with some of the state‐of‐the‐art techniques. With the emergence of the Internet of Things Technology, such IDS can be deployed for securing the IoT servers in future. Wireless payment systems can be secured by building and deploying IDS. A secure integrated network management can be achieved which is error‐free and thereby improving performance.
A spectinomyciin resistance determinant from the spectinomycin producerStreptomyces flavopersicus

Summary: The spectinomycin (Sp) resistance determinant from Streptomyces flavopersicus was cloned into Streptomyces lividans using the plasmid vector pIJ699. A plasmid, pDGL15, with a 3.65 kb insert from S. flavopersicus conferring resistance to Sp was isolated. DNA sequence analysis of the 3651 bp DNA insert revealed four open reading frames (ORFs). The amino acid sequence deduced from one ORF (SpcN) showed a high degree of similarity to an aminoglycoside phosphotransferase (StrN) and from a second one (SpcR) to a regulatory protein (StrR) of the streptomycin biosynthesis gene cluster from S. griseus. The two other ORFs were incomplete and the deduced amino acid sequences showed similarities to an amidinotransferase encoded in the streptomycin biosynthesis gene cluster of S. griseus and to the transposase of IS112, respectively. Expression of the spcN gene in E. coli under the control of tac promoter conferred Sp resistance to the cells. An enzymic assay confirmed that the gene product of spcN is an ATP-dependent aminoglycoside phosphotransferase which phosphoryiates Sp and actinamine, the aminocyclitol moiety of Sp.
Characterization of Aerosol Hygroscopicity Over the Northeast Pacific Ocean: Impacts on Prediction of CCN and Stratocumulus Cloud Droplet Number Concentrations

During the Marine Aerosol Cloud and Wildfire Study (MACAWS) in June and July of 2018, aerosol composition and cloud condensation nuclei (CCN) properties were measured over the N.E. Pacific to characterize the influence of aerosol hygroscopicity on predictions of ambient CCN and stratocumulus cloud droplet number concentrations (CDNC). Three vertical regions were characterized, corresponding to the marine boundary layer (MBL), an above‐cloud organic aerosol layer (AC‐OAL), and the free troposphere (FT) above the AC‐OAL. The aerosol hygroscopicity parameter (κ) was calculated from CCN measurements (κCCN) and bulk aerosol mass spectrometer (AMS) measurements (κAMS). Within the MBL, measured hygroscopicities varied between values typical of both continental environments (~0.2) and remote marine locations (~0.7). For most flights, CCN closure was achieved within 20% in the MBL. For five of the seven flights, assuming a constant aerosol size distribution produced similar or better CCN closure than assuming a constant “marine” hygroscopicity (κ = 0.72). An aerosol‐cloud parcel model was used to characterize the sensitivity of predicted stratocumulus CDNC to aerosol hygroscopicity, size distribution properties, and updraft velocity. Average CDNC sensitivity to accumulation mode aerosol hygroscopicity is 39% as large as the sensitivity to the geometric median diameter in this environment. Simulations suggest CDNC sensitivity to hygroscopicity is largest in marine stratocumulus with low updraft velocities (<0.2 m s−1), where accumulation mode particles are most relevant to CDNC, and in marine stratocumulus or cumulus with large updraft velocities (>0.6 m s−1), where hygroscopic properties of the Aitken mode dominate hygroscopicity sensitivity.
Simulation Study on On-Line MTPA/MTPV Trajectory Tracking in PMSMs with Power Management

Abstract This paper proposes an on-line maximum torque per ampere (MTPA)/maximum torque per voltage (MTPV) trajectory tracking method in permanent magnet synchronous machines (PMSMs) with power management. The on-line MTPA/MTPV machine current trajectory tracking algorithm is developed from PMSM model. Maximum source current and machine current are regulated to enhance hardware protection during machine current trajectory tracking. The maximum source current management is achieved by iterating within the current trajectory tracking algorithm over continuous torque command modifications based on power flow analysis, and the maximum machine current management is achieved by torque command limiting based on current angle modulation. Different from the existing techniques in literature, the proposed method has an unique feature of providing on-line regulation of source current, while maintaining on-line MTPA/MTPV trajectory tracking in PMSMs. It also provides machine and inverter overcurrent regulation to enhance their protection. In addition, the proposed method is flexible to tune and does not require off-line calibration. The effectiveness of the proposed method is confirmed by simulation results in MATLAB.
Do Progressive Sensorimotor Training Devices Produce A Graded Increase in Centre of Mass Displacement During Unipedal Balance Exercises in Athletes

Progression of the difficulty of agility exercises in sport is often achieved by changing the stability of the support surface via graded sensorimotor training devices. However, little is known about the challenge imposed to postural equilibrium by these graded devices. This study quantified the instability provided by four sensorimotor training devices typically used to enhance athletic performance; three progressively unstable balance pads (ST1–3) and an oscillatory platform (PM). Twenty-five (13 female, 12 male) young adults (age, 26 ± 3 yr; height, 1.76 ± 0.10 m; and weight, 69 ± 12 kg), completed seven unipedal balance conditions involving stable and progressively unstable surfaces that involved four sensorimotor training devices (ST1-3, PM) and their combination (PM-ST1, PM-ST2). An inertial sensor, mounted over the lumbar spine, was used to monitor Centre of Mass (COM) displacement in each condition. Potential differences in COM displacement between conditions were assessed using a mixed-model analysis of variance. COM displacement differed between training devices; with a progressive, though non-linear, increase in COM displacement from the most (ST1) to the least (ST3) stable balance pad. However, there was no significant difference in COM displacement between the least stable balance pad (ST3) and the oscillatory platform used in isolation (PM) or in combination with balance pads (PM-ST1, PM-ST2). These novel findings have important practical implications for the design of progressive sensorimotor training programs in sport.
Segmenting Excessive Alcohol Consumers: Implications for Social Marketing

While extant studies have mainly investigated differences between drinkers and non-drinkers, the literature on segmenting heavy drinkers and profiling them is surprisingly scarce. This study makes a significant contribution to the social marketing literature by illustrating a novel way of targeting heavy drinkers by utilizing their health management styles and provides useful insights into understanding how segmentation could be a valuable tool for developing effective social marketing programmes that are aimed at reducing excessive alcohol consumption. Analysis of data collected through the HINTS study reveals a two-cluster segmentation model. The two segments of heavy drinkers distinctly differ in terms of the extent of reliance and trust they place on health service professionals. Hence, the segmentation analysis provides interesting and novel insights into the level of dependence of heavy drinkers on the health care system and their health management styles. The study provides an actionable perspective for future research, public policy and social marketing.
Nasal carriage and methicillin resistance of Staphylococcus aureus in patients and hospital staff in a tertiary referral center setting

The prevalence of nasal carriage of Staphylococcus aureus and methicillin-resistant S. aureus (MRSA) were studied from June 2006 – 2007 among in-patients and hospital staff in a tertiary referral center setting in Ankara, Turkey. Methicillin resistance was evaluated by Kirby-Bauer disc diffusion method. Of 438 people, 106 (24.2%) were nasal carriers of S. aureus. The prevalence of nasal carriers for S. aureus were not significantly different between the hospital staff, in-patients and out-patients (p>0.05). The overall prevalence of MRSA was 23.6%. The prevalence of MRSA carrier hospital staffs and in-patients was not significantly different (p>0.05). However, the prevalence of MRSA was higher in the medical staffs and in-patients compared to out-patients (p<0.01). The prevalence of nasal carriers is higher in the hospital staff and in-patients compared to out-patients. Therefore, even a tertiary referral hospital can be the source of methicillin resistance as well as transmission of the resistance. Key words: Nasal carrier, methicillin-resistant Staphylococcus aureus in-patients and hospital staff.
A More Social Science: Barriers and Incentives for Scientists Engaging in Policy

Scientists are increasingly called upon to engage in policy formulation, but the literature on engagement is strong on speculation and weak on evidence. Using a survey administered at several broadly “ecological” conferences, we investigated: (1) the extent to which respondents engage in policy-related activities (including reporting scientific results, interpreting science for policy makers, integrating science into decision making, taking a position on a policy issue, and acting as a decision maker); (2) what factors best explain these types of engagement; and (3) whether respondents' activity levels match their stated beliefs on such activities. Different factors explain different forms of participation. Past negative experience was identified as a barrier to taking part in policy, while self-perceived competence in navigating the science–policy interface was consistently important in explaining activity across all engagement types, highlighting the importance of training programs linking scientists to policy. Many respondents believed that scientists should interpret, integrate, and advocate, which contrasts with previous research and relatively low levels of self-reported participation in policy.
The complete mitochondrial genome of Macrourus whitsoni (Gadiformes, Macrouridae)

Abstract The complete mitochondrial genome of Macrourus witsoni was determined in this study by the Long-read Technology, such as PacBio Sequel System. The Long-read Technology, which can sequence continuously the whole vertebrate mitochondrial genome, allows more accurate genomes to be completed. The circular form of its mitochondrial genome was 16,714bp, which contained 13 protein-coding genes, 22 tRNA, and 2 rRNA. The gene orders of M.witsoni was identical to that of the other species of Macrouridae family. Phylogenetic analysis indicated M. witsoni was mostly close to C.kishinouyei in the Macrouridae family.
Impacts of airborne pollutants on soil fauna

▪ Abstract The impacts of airborne pollutants have been studied in only a few groups of soil animals, notably protozoans, nematodes, potworms, earthworms, mites, and collembolans. Pollutants in the form of acid depositions, which contain SO42−, NOx, H+, heavy metals, and some organic compounds, are not homogeneously distributed on the landscape. Deposition patterns depend mainly on landscape configuration and plant cover. Airborne pollutants affect soil animals both directly and indirectly. Direct toxic effects are associated with uptake of free acidic water from the environment by some soil animals and with consumption of polluted food by others. Indirect effects are mediated primarily through disappearance or reduction of the food resources (microflora and microfauna) of soil animals, changes in organic matter content, and modification of microclimate. In the field, changes in competition among species are probably important factors that influence the soil animal community structure as well as the react.
An Analysis of the Perception of Psoriasis Symptoms and the Impact on Willingness to Seek Medical Attention

Background: Most people with psoriasis do not have a medical visit for psoriasis within a given year. Objective: To assess individuals’ perceptions of the impact of psoriasis symptoms and how this impact affects willingness to seek medical attention. Methods: A total of 302 subjects with self-reported psoriasis were recruited through Amazon Mechanical Turk and surveyed via Qualtrics to assess the impact of psoriasis on their daily lives and willingness to seek medical care. Comparisons were made between subjects presented with either an image of mild psoriasis or severe psoriasis. Outcome measures were evaluated on a 10-point Likert scale and compared using 1-way analysis of variance and 2-group t tests. Results: In the mild and severe psoriasis groups, those who rated the impact on their daily life ≥8 (1-10 scale) reported a greater willingness to seek medical attention for their psoriasis (M = 9.1, SD = 1.5) compared to those who rated the impact between 6 and 7 (M = 7.5, SD = 1.9, P < .01) and between 1 and 5 (M = 6.4, SD = 2.4, P < .01). Those who rated the impact between 6 and 7 (M = 7.5, SD = 1.9) reported a greater willingness to seek medical attention compared to those who rated the impact between 1 and 5 (M = 6.4, SD = 2.4, P < .01). Conclusion: Patients with psoriasis may not visit a dermatologist in part due to not viewing their symptoms as severe enough to seek medical attention.
Selective depletion of riboflavine from beer using membranes incorporating imprinted polymer particles

The synthesis and characterization of imprinted polymer composite membranes and use of the membranes for depleting riboflavine from beer are hereby reported. The membranes were prepared by phase inversion of a suspension of imprinted polymer particles, which had previously been shown to exhibit selective recognition of vitamin B2 in aqueous media in a solution of poly-methylmethacrylate and polyethylenglycol in acetone. Membranes with different loads of imprinted particles were prepared and characterized by scanning electron microscopy, Fourier-transform infrared chemical imaging and permeability measurements. Subsequently they were tested in both static and dynamic partitioning experiments concerning their ability to bind riboflavine versus other competing solutes such as lumichrome and uridine. The membranes exhibited a pronounced selectivity for riboflavine and were capable of partially depleting nearly 80% of the vitamin from beer. Meanwhile, a membrane prepared identically using nonimprinted particles resulted in a maximum removal of nearly 50%, however, with low selectivity. PRACTICAL APPLICATIONS Membranes incorporating molecularly imprinted polymer particles is a new tool for food processing allowing the traceless removal of preselected substances, e.g., flavors, spoilage agents or impurities. As suggested by the results presented in this contribution, such membranes could potentially find use in the brewing industry for selective depletion of riboflavine thus leading to enhanced beer stability.
