Epistemic clashes in network science: Mapping the tensions between idiographic and nomothetic subcultures

This article maps a controversy in network science over the last 15 years, dividing the field about the epistemic status of a central notion, scale-freeness. The article accounts for the two main disputes, in 2005 and in 2018, as they unfolded in academic publications and on social media. This article analyzes the conflict, and the reasons why it reignited in 2018, to the surprise of many. It is argued that (1) the concept of complex networks is shared by the distinct subcultures of theorists and experimentalists; and that (2) these subcultures have incompatible approaches to knowledge: nomothetic (scale-freeness is the sign of a universal law) and idiographic (scale-freeness is an empirical characterization). Following Galison, this article contends that network science is a trading zone where theorists and experimentalists can trade knowledge across the epistemic divide.

E-mail: pauloleal@ctiveterinario.com. br The vector-borne diseases in dogs are caused by pathogens with different biological behaviors that result in different clinical and laboratory findings presentations. The diagnosis of these diseases is a challenge for veterinarians and those caused by obligate intracellular blood parasites of blood cells constitute vogeli of Babesia canis, Anaplasma platys, Erhlichia canis and Mycoplasma canis. This paper looks at the frequency of these parasites in 204 laboratory results dogs treated at the Intensive Care Unit and Emergency Veterinary through CBC and research of blood parasites in blood estiraco and concentrate platelets and leukocytes. There was one or more species of haemoparasites in 132 dogs (64.7%) through blood samples. They were observed: 7 (5.3%) dogs for B. c. vogeli, 64 (48.5%) for A. platys, 16 (12.2%) for M. canis, A. platys and E. canis in one (0.7%), A. platys and M. canis in 36 dogs (27.3%), M. canis and B. c. vogeli five (3.8%), M. canis and E. canis one (0.7%), A. platys, B. c. vogeli and M. canis in two (1.50%), confirming thus the high frequency of blood parasites in pet dogs in an urban environment, treated in the routine, the importance of viewing parasitic inclusions in leukocytes, platelets and red blood cells, It thus demonstrating the need for greater attention to the diagnosis of multiple infections by different parasitic agents in order to determine the most effective treatment.
Experimental and Numerical Quantification of the Aerodynamic Damping of a Turbine Blisk

Aerodynamic damping is the key parameter to determine the stability of vibrating blade rows in turbomachinery design. Both, the assessments of flutter and forced response vibrations need an accurate estimate of the aerodynamic damping to reduce the risk of high cycle fatigue that may result in blade loss. However, only very few attempts have been made to measure the aerodynamic damping of rotating blade rows experimentally under realistic operating conditions, but always with friction damping being present. This study closes the gap by providing an experiment in which a turbine blisk is used to eliminate friction damping at the blade roots and thereby isolate aerodynamic damping. The blades are excited acoustically and the resulting nodal diameter modes are measured using an optical tip-timing system in order to realize a fully non-intrusive setup. The measured vibration data are fitted to a single degree-of-freedom model (SDOF) to determine the aerodynamic damping. The results are in good accordance with the time-linearized CFD simulation. It is observed, however, that not only the sweep rate of the acoustic excitation but also the variation of the rotational frequency during the sweep excitation, and the excitation frequency influence the apparent damping.
α-Tocopherol Foliar Spray and Translocation Mediates Growth, Photosynthetic Pigments, Nutrient Uptake, and Oxidative Defense in Maize (Zea mays L.) under Drought Stress

A pot experiment was conducted to assess the induction of drought tolerance in maize by foliar-applied α-tocopherol at early growth stage. Experiment was comprised two maize cultivars (Agaiti-2002 and EV-1098), two water stress levels (70% and 100% field capacity), and two α-tocopherol levels (0 mmol and 50 mmol) as foliar spray. Experiment was arranged in a completely randomized design in factorial arrangement with three replications of each treatment. α-tocopherol was applied foliary at the early vegetative stage. Water stress reduced the growth of maize plants with an increase in lipid peroxidation in both maize cultivars. Contents of non-enzymatic antioxidants and activities of antioxidant enzymes increased in studied plant parts under drought, while the nutrient uptake was decreased. Foliary-applied α-tocopherol improved the growth of both maize cultivars, associated with improvements in photosynthetic pigment, water relations, antioxidative mechanism, and better nutrient acquisition in root and shoot along with tocopherol contents and a decrease in lipid peroxidation. Furthermore, the increase of tocopherol levels in roots after α-Toc foliar application confers its basipetal translocation. In conclusion, the findings confer the role of foliar-applied α-tocopherol in the induction of drought tolerance of maize associated with tissue specific improvements in antioxidative defense mechanism through its translocation.
The effect of acquisition resolution on orientation decoding from V1: comparison of 3T and 7T

Previously published results indicate that the accuracy of decoding visual orientation from 7 Tesla fMRI data of V1 peaks at spatial acquisition resolutions that are routinely accessible with more conventional 3 Tesla scanners. This study directly compares the decoding performance between a 3 Tesla and a 7 Tesla dataset that were acquired using the same stimulation paradigm by applying an identical analysis procedure. The results indicate that decoding models built on 3 Tesla data are comparatively impaired. Moreover, we found no evidence for a strong coupling of BOLD signal change magnitude or temporal signal to noise ratio (tSNR) with decoding performance. Direct enhancement of tSNR via multiband fMRI acquisition at the same resolution did not translate into improved decoding performance. Additional voxel selection can boost 3 Tesla decoding performance to the 7 Tesla level only at a 3 mm acquisition resolution. In both datasets the BOLD signal available for orientation decoding is spatially broadband, but, consistent with the size of the BOLD point-spread-function, decoding models at 3 Tesla utilize spatially coarser image components.
Epidemiology of meningitis in children in a Brazilian northeastern state

To describe the epidemiological profile of meningitis in children under the age of five resident in the State of Paraiba between 2007 and 2017. A time series analysis in a descriptive epidemiological study, whose population comprised all the cases confirmed by the Executive Management of Health Surveillance of Paraiba. The obtained sample was analyzed through statistical resources using the SPSS software version 18.0. The age group indicated an increased concentration in children under the age of 1year old, corresponding to a coefficient of incidence of 24.1/10.000 habitants. The criteria of confirmation indicated 44.3% by means of the chemical and cytological examination, 77.6% progressed to hospital discharge and 9.8% to death. Regarding the temporal distribution of the cases, the year 2012 appears with the highest number of confirmed cases 20.06% and 2015 presented the lowest incidence 3.61%, within the period studied. The combat of Meningitis is still characterized as a relevant issue in the State, despite the declining tendency of confirmed cases, the incidence may still be considered as being high due to the vaccine protection that is available.
Sensory evaluation and antioxidant capacity as quality parameters in the development of a banana, strawberry and juçara smoothie

Abstract In the present study a banana, strawberry and jucara smoothie was developed using an experimental mixture design. The jucara proportion was kept constant while the banana:strawberry ratio varied and the main responses were the sensory acceptability and the antioxidant capacity. From five formulations, only the one with the highest percentage of strawberry was rejected, most likely due to its lower sugar content and higher acidity. In general, panelists chose the sweeter formulations, which were those with a higher percentage of banana. Relating to the consistency, the best formulation was the one containing the same proportion of strawberry and banana pulp, which provided a better flow to the product. Additionally, this sample showed intermediate values of phenolic compounds and antioxidant capacity, as well as desirable physicochemical characteristics. In spite of being possible to obtain four formulations with good sensory acceptance, the one with equal amounts of banana and strawberry pulp is highlighted due to its antioxidant capacity and sensory characteristics, statistically corroborated by the desirability function.
Spindle assembly checkpoint strength is governed by cell size and PAR-mediated cell fate determination in C. elegans

The spindle assembly checkpoint (SAC) is a conserved mitotic regulator that preserves genome stability. Despite its central role in preserving the fidelity of mitosis, the strength of the SAC varies widely between cell types. How the SAC is adapted to different cellular contexts remains largely unknown. Here we show that both cell size and cell fate impact SAC strength. While smaller cells have a stronger SAC, cells with a germline fate show increased SAC activity relative to their somatic counterparts across all cell sizes. We find that enhanced SAC activity in the germline blastomere P1 requires proper specification of cell fate downstream of the conserved PAR polarity proteins, supporting a model in which checkpoint factors are distributed asymmetrically during early germ cell divisions. Our results indicate that size scaling of SAC activity is modulated by cell fate and reveal a novel interaction between asymmetric cell division and the SAC.
Ecological comparison between duckweeds in central Italy: The invasive Lemna minuta vs the native L. minor

Abstract The American duckweed Lemna minuta shows an invasive behaviour in Europe, causing weed problems in aquatic habitats there. Few studies addressed this species’ ecological requirements for a suitable establishment in a site. In this paper, L. minuta populations were analysed through field surveys so as (1) to define the autoecology of this duckweed as regards the main environmental factors characterizing invaded habitats, and (2) to identify possible overlaps/differences in ecological requirements between the alien L. minuta and the common native L. minor, with which it is often associated and in direct competition. The occurrence/abundance of the two species and environmental data were collected from 41 wetlands in central Italy. Currently, L. minuta is more common and abundant than L. minor in the study-area, despite its recent arrival there (2007). The two species have a partially overlapped autoecology. However, L. minuta differs from L. minor since it occurs in waters which are less alkaline, slightly less warm, and richer in nitrates. It shows tolerance for environmental conditions which are limiting for most of macrophytes, including L. minor, such as high shading and low water oxygenation. This enables L. minuta to increase its invasion potentiality and thus to enlarge its distribution area.
Bionic Drag Reduction for Box Girders Based on Ostracion cubicus

With the development trend of large-scale and flexible structures in engineering, the research on drag reduction of structures becomes more urgent. This paper presents a drag reduction design method for box girders based on the bionic method. Through the analysis of the Ostracion cubicus body shape, three features of the “fish mouth”, which were helpful for drag reduction were extracted. Then the bionic design model with the height of the box girder (D) as the design variable was obtained. By attaching lightweight materials to the windward side, the bionic shape of the structure can be realized without changing the loading characteristics of the original structure. Taking a box girder (rectangular cylinder, side ratio B/D = 0.6) as a prototype, the flow around two structures (rectangular cylinder and bionic attachment cylinder) was numerically simulated. The results show that the drag coefficient of the bionic attachment structure is reduced by 66.5%. The reduction of wind-load means that this method can save energy consumption of the equipment. Meanwhile, the aerodynamic parameter oscillation of the structure is weakened, which represents that the bionic attachment structure can effectively reduce the wind-induced vibration on the structure and improve the stability of the structure in the wind field.
Cellulose micro‐ and nanofibrils (CMNF) manufacturing ‐ financial and risk assessment

Conversion economics, risk, and financial analyses for an industrial facility manufacturing cellulose micro‐ and nanofibrils (CMNF) from wood pulp is presented. Process data is based on mass and energy balances from a pilot facility in the University of Maine. Here, CMNF is produced from untreated wood pulp by using disk refining, with an assumed production capacity of 50 t (dry metric ton equivalent) per day. Stand‐alone and co‐location manufacturing facilities were simulated and assessed. Minimum product selling prices (MPSP, estimated to achieve a 16% hurdle rate) for different scenarios ranged from USD 1893/t CMNF to USD 2440/t CMNF (dry equivalent). Pulp and energy consumption were identified as major cost drivers. Consequently, it was found that the use of alternative feedstock, in addition to co‐location configuration, can reduce MPSP by 37%. Since estimated MPSP of CMNF is lower than cellulose nanocrystals (CNC) – both estimated to achieve a 16% hurdle rate, we believe market adoption of CMNF in the near term is more promising, regardless of specific applications. This study provides state of the art business intelligence information on the conversion economics, risk, and financial analyses for CMNF manufacturing. Thus, the data represents valuable information to entrepreneurs, R&D scientists, and product developers who plan to adopt CMNF in their processes and products. © 2017 Society of Chemical Industry and John Wiley & Sons, Ltd
Nota sobre la dieta de la Lechucita Bigotona, Xenoglaux loweryi en Yambrasbamba, Amazonas

We present results of an analysis of faecal samples from the long whiskered owlet (Xenoglaux loweryi), a species endemic to Peru and considered Endangered by the IUCN. It inhabits humid montane forests on the eastern slopes of the Andean cordillera. We collected four faecal samples from different individuals during ecological monitoring. Monitoring was carried out between January and September 2014 in the area known locally as “La Jalca” in the Yambrasbamba community, Amazonas. Samples were collected in May, June, August and September, respectively. Analysis revealed fragments characteristic of the orders Coleoptera, Hymenoptera, Ortoptera and Lepidoptera. Results confirm that small insects form part of the diet of the long whiskered owlet, similar to other small Strigidos.
Chemometric Characterization of Eight Monovarietal Algerian Virgin Olive Oils

Differences in triacylglycerol, fatty acid, squa-lene, and tocopherol compositions were demonstrated between 8 varieties of virgin olive oils (Aberkane, Aguenaou, Aharoun, Aimel, Bouchouk Guergour, Bouichret, Chemlal, and Sigoise) from Petite Kabylie area, north eastern Algeria. Fatty acid and triacylglycerol morphotypes characterized each variety. A principal component analysis, based on tria-cylglycerol, fatty acid, and squalene compositions, differentiates between varieties. Minor fatty acids and squalene, usually not taken into account individually in authentication studies, are strongly involved in this differentiation, whereas the discriminant power of tocopherols is weak. Soft Independent Modeling of Class Analogy classification using chemical compositions as variables showed a high potential to authenticate the varietal origin of Algerian virgin olive oils.
Preliminary study of Endomycodiversity among three ethnomedicinal plants family Meliaceae in Nigeria

The natives as well as the ethnic tribes inhabiting the study area of this research work value the plants as a source of medicine to cure some of the ailments. Many of the pharmaceutical compounds produced by medicinal plants are reportedly produced by their endophytic fungi. Hence, it is important to study endophytic fungi of ethnomedicinal plants and their biodiversity. Modified surface sterilization techniques using 3% surfactant and 70% sterilant was applied for the explants before culturing, various biochemical tests such as wet mount using methylene blue, dalamau and urease test was employed for macro and microscopic endophytic fungal identification. Altogether 756 segments of which 26 segments each from leaves (young) and stem (twig) tissues of the respective plants was screened using modified surface sterilization techniques. Thirty one species of endophytic fungi was isolated. Based on taxonomical classification 26 belongs to Ascomycetes 2 Basidiomycetes and 5 species were recorded unidentified. The highest species richness as well as overall frequency of colonization was showed on stems of P. kotschi (20.7%) by Cladosporium species and Fusarium manilliforme from leaves (18%); Rhizoctonia species proved highest frequency of colonization on K. senegalensis stems (15.6%) followed by Cladosporium species on leaves (13.9%). Cryptococcus species showed the highest frequency of colonization on stems of A. indica (14.9%) while Cladosporium species showed the highest colonization on leaves (11%).
Correlating Heart Rate Variability to Glucose Levels

A study has been undertaken under the umbrella of a project focusing on noninvasive electrocardiogram (ECG) monitoring. The main goal of the study is to figure out which heart-rate variability parameter has the ability to give the most accurate information for the Glucose level of a patient. The results show that for short term continuous measurements (minimum five minutes) and without extrasystoles or noise in the ECG signal the Root Mean Square Successive Differences parameter has demonstrated better correlation capabilities with a glucose level compared to other parameters. On the other hand, for long term measurements (hourly lengths), the better indicator came to be Standard Deviation of Normal to Normal intervals however, not the combined Standard Deviation of Normal to Normal intervals but the averages of Standard Deviations of Normal to Normal intervals calculated on separate sequences.
Predictors for Remission after Transsphenoidal Surgery in Acromegaly: A Dutch Multicenter Study

Abstract Context Transsphenoidal surgery (TSS) is the primary treatment of choice in acromegaly. It is important to identify patients in whom surgical cure is not attainable at an early stage, both to inform patients on expected treatment outcome and to select those who are more likely to need additional therapy. Objective To identify predictors for remission after TSS in acromegaly. Methods Large multicenter study with retrospective data collection from 3 tertiary neurosurgical referral centers in The Netherlands. We analyzed clinical data since 2000 from 3 cohorts (Groningen, Nijmegen, and Rotterdam, total n = 282). Multivariate regression models were used to identify predictors of early biochemical remission (12 weeks to 1 year postoperatively) according to the 2010 consensus criteria, long-term remission (age- and sex-normalized insulin-like growth factor 1 [IGF-1] and the absence of postoperative treatment until last follow-up), and relative IGF-1 and growth hormone [GH] reduction. Results A larger maximum tumor diameter (odds ratio [OR] 0.91, 95% CI 0.87-0.96, P ≤ .0001) was associated with a lower chance of early biochemical remission. A larger maximum tumor diameter (OR 0.93, 95% CI 0.89-0.97, P = .0022) and a higher random GH concentration at diagnosis (OR 0.98, 95% CI 0.96-0.99, P = .0053) were associated with a lower chance of long-term remission. Conclusion Maximum tumor diameter and random GH concentration at diagnosis are the best predictors for remission after TSS in acromegaly.
