Abstract. Two parallel field studies were conducted simultaneously at both urban and
rural sites in Beijing from 1 to 29 November 2016. An online single-particle
chemical composition analysis was used as a tracer system to investigate the
impact of heating activities and the formation of haze events. Central
heating elevated EC-Nit (elemental carbon-nitrate), EC-Nit-Sul (EC-nitrate-sulfate), and ECOC-Nit (ECOC: internal-mixed elemental carbon and organic carbon) levels by 1.5–2.0 times
due to the increased use of coal in the urban areas. However, in the rural
areas, residential heating, which mainly consumes low-quality coal, and
biomass burning elevated ECOC-Nit-Sul, NaK-Nit, and OC-Sul levels by
1.2–1.5 times. Four severe haze events (hourly PM2.5 > 200 µg m−3) occurred at both sites during the studies. In each
event, a pattern of transport and accumulation was found. In the first
stage of the pattern, particles were regionally transported from the south
and southwest and accumulated under air stagnation, creating significant
secondary formation, then PM2.5 was elevated to 300 µg m−3.
At both sites, the severe haze occurred due to different patterns of local
emission, transport, and secondary processes. At Pinggu (PG), the sulfate-rich
residential coal burning particles were dominant. The regional transport
between PG and Peking University (PKU) was simulated using the Weather Research and Forecasting HYbrid Single-Particle
Lagrangian Integrated Trajectory (WRF-HYSPLIT) model, confirming
that the transport from PG to PKU was significant, but PKU to PG occurred
occasionally. These cases can explain the serious air pollution in the urban
areas of Beijing and the interaction between urban and rural areas. This
study can provide references for enhancing our understanding of haze
formation in Beijing.

Published: August 2020

Abstract. Ground-penetrating radar (GPR) and seismic imaging have
proven to be important tools for the characterization of rock volumes. Both
methods provide information about the physical rock mass properties and
geological structures away from boreholes or tunnel walls. Here, we present
the results from a geophysical characterization campaign that was conducted
as part of a decametre-scale hydraulic stimulation experiment in the
crystalline rock volume of the Grimsel Test Site (central Switzerland). For
this characterization experiment, we used tunnel-based GPR reflection
imaging as well as seismic travel-time tomography to investigate the volumes
between several tunnels and boreholes. The interpretation of the GPR data
with respect to geological structures is based on the unmigrated and
migrated images. For the tomographic analysis of the seismic first-arrival
travel-time data, we inverted for an anisotropic velocity model described by
the Thomsen parameters v0, ϵ and δ to account for the
rock mass foliation. Subsequently, the GPR and seismic images were
interpreted in combination with the geological model of the test volume and
the known in situ stress states. We found that the ductile shear zones are
clearly imaged by GPR and show an increase in seismic anisotropy due to a
stronger foliation, while they are not visible in the p-wave (v0)
velocity model. Regions of decreased seismic p-wave velocity, however,
correlate with regions of high fracture density. For geophysical
characterization of potential deep geothermal reservoirs, our results imply
that wireline-compatible borehole GPR should be considered for shear zone
characterization, and that seismic anisotropy and velocity information are
desirable to acquire in order to gain information about ductile shear zones
and fracture density, respectively.
Evolutionary Automata Networks: Henri Atlan’s Physical Theory of Intentionality
Authors: Senatore Mauro 
Published: August 2020

ABSTRACT
This article focuses on the project of a mechanistic and posthuman history of life as developed by one of the major figures of contemporary biological thought, the biophysicist and theorist of auto-organization Henri Atlan. In particular, it explores Atlan’s elaboration of this project in relation to the recent history of biological thought and in contrast to what he identifies as the phenomenological and humanist reduction of natural sciences. As this exploration develops, it shows that Atlan takes up a conception of language, qua natural language, as the analogical and differential code of his history of life. In doing so, it highlights two problems implicit in Atlan’s elaboration of his project: the demarcation of natural language from the artificial and metaphorical language of cultural discourses and the conception of properly called intentional auto-organization. Apropos of this second problem, it is argued that, despite Atlan’s aim of offering a physical theory of intentionality in general, including human and humanlike intentionality, his description of intentional auto-organization seems, in turn, to subscribe to what he designates as the phenomenological and humanist presupposition of sense-giving consciousness.
Transhumanist Contraceptives in June Caldwell’s “The Implant”
Authors: Romero Vanessa Roldán 
Published: August 2020

ABSTRACT
The rise of new and increasingly sophisticated technology in Western society has not left the West’s social relations and philosophies unaffected. One trend of thought inspired by technological advances is transhumanism, which defends the further “evolution” of the human species through direct technological interventions to provide the human body with a new functionality. Among the endless possibilities for prosthetic and other interventions in the human body is the use of prosthetic contraceptives to control female bodies and fertility. The use and exploration of prostheses as contraceptives can be traced in the Irish former journalist June Caldwell’s collection of short stories Room Little Darker (Caldwell 2018). She explores a number of social issues in a conservative and rather patriarchal fictional twenty-first-century Dublin, paying close attention to the genderization of bodies through sophisticated technology. In “The Implant,” the short story analyzed in this paper, the body female protagonist undergoes an operation that will implant a prosthetic contraceptive as a kind of self-punishment after her long-term boyfriend commits adultery. The aim of this paper is to find evidence of how the prosthetic contraceptive reconfigures the female protagonist into a transhuman subject and the possible consequences—that is, to discern whether the prosthetic contraceptive empowers or oppresses her under the new transhuman or not.

Published: August 2020

The knowledge of the radiative characteristics of an area is essential to understanding the flows of matter and energy. The value of the Light Extinction Coefficient (K) is a parameter that describes the efficiency of the interception of light in a given canopy, being required, as input, for several SWAP (Soil-Water-Atmosphere-Plant) models, which allow the characterization of the interactive properties among soil, plant and atmosphere concerning these exchanges of matter and energy. This study aimed to obtain the light extinction coefficient (K) for a savanna fragment located in the urban area of Cuiabá. The used data correspond to one measurement each month, totaling twelve measurements in 30 points during the period from October 2014 to September 2015. The measured variables were the LAI (Leaf Area Index), the photosynthetically active incident radiation (PARinc) and the transmitted radiation (PARtrans), and the calculated ones were the zenith angle (Zh) and the extinction coefficient (K). Was observed an annual variability for the light extinction coefficient between 0.49 and 0.69. There are seasonal changes that interfere with the canopy geometry and the position of the study area in relation to the solar radiation incidence, concluding that the K variability is predominantly temporal.

Authors: Mishra Archana , Soren Narendra Nath , Ganguly Sristi 
Published: August 2020

Aims: To study the clinical profile of HIV infected children and correlate them with the CD4 count at the time of presentation.
Study Design: Hospital based observational study
Place and Duration of Study: ART centre of SCBMCH and Department of Pediatrics, SVPPGIP, Cuttack, Odisha during the period October 2017 to September 2019.
Methodology: All children aged between 1.5 to 15 years who were confirmed to be HIV positive by ELISA or immunocomb II, either at present or past were included in the study. They were subjected to CD4 count testing, along with nutritional assessment and screened for opportunistic infections, apart from their socio-demographic details. All quantitative variables including age, weight, height, were compared by unpaired t-test. Categorical variables like sex mode of transmission were compared by chi-square test. Variables like clinical staging, immunological staging and CD4 counts were measured at presentation and analyzed with repeated ANOVA at 5% level of significance to allow for multiple comparisons. P<0.05 was considered significant and inferences were drawn.
Results: Out of 103 cases, majority belonged to age 4- 7 years and 59.2% were malnourished. 24.3% were asymptomatic, with the most common clinical features noted were fever (65%), cough (47.8%), recurrent diarrhoea (41.8%) and weight loss (40.8%). The incidence of opportunistic infections was 24.3%, with tuberculosis (40%) and herpes zoster (36%) leading the list. Most cases (37.87%) came under WHO clinical stage-III. A significant correlation was found between CD4 count and age, WHO clinical staging, opportunistic infections in the population. Lower CD4 counts were associated with younger age, lower staging and less risk for symptoms and infections.
Conclusion: CD4 count is a reliable market to assess the staging and risk for opportunistic infections in pediatric HIV and thus can be used as screening tool for complications/ deterioration in the child, for better management.

Optimization of Heat and Mass Transfer Process in Single Screw Floating Fish Feed Extruder
Authors: Odunayo Ogundana , Ajiboye Oyerinde 
Published: August 2020

To optimize the extrusion conditions of locally developed single screw floating fish feed extruder. A factorial experiment in completely randomized design was employed to study the effect of extrusion variables: feed moisture content (20, 30, and 40% wet basis), screw speed (158.5, 245, 334 rpm), die size (4, 6, 8, mm) while checking for their effect on Product temperature of the feed produced. Product temperature is strongly related to the extrusion process parameters under study. Product temperature decreased with increasing moisture content. Optimum condition was found at 74.11⁰C at the feed section, 80.83⁰C at compression section and 85.15⁰C at metering section, screw speed at 330.5 rpm, feed rate at 0.6 kg/min, die size at 7.47 mm, moisture content at 39.87%, particle size at 1.1., and the coefficient for the final model is 0.93 which indicated that the model is good. The extruder was found to be cost efficient for floating fish feed production. Thus, model-fitting using response surface methodology was performed to examine their effect on product temperature. Quadratic coefficients fit the extrusion data very well, better than linear models. The equations relating the various dependent and independent variables were established to predict the performance of the machine.
The Influence of CEO’s Demographic Characteristics on Tax Aggressiveness in Family Firm
Authors: Astutik Dwi , Venusita Lintang 
Published: August 2020

This research aims to analyze how the educational background, tenure, and gender of Chief Executive Officer (CEO) affect tax aggressiveness in a family firm. Independent varia­bles comprise the educational background, tenure, and gender of CEO while tax aggres­sive­­ness plays as dependent variable. In addition to those three parameters, the controlled variable also includes leverage and profitability. Population and sample of this research were taken from family firms registered in the Indonesian Stock Exchange during 2013 - 2016. With the purposive sampling, the number of total samples and sampling units in this research are 42 and 168, respectively. Furthermore, documentation techniques manifested in financial state­ment and annual report are used as data collection method where panel data regression with a fixed effect model is employed for statistical analysis. The present results demonstrate that the educational background and profitability significantly give a negative effect on the tax aggressiveness whereas the tenure and leverage considerably contribute to a positive conse­quence in the tax aggressiveness. Interestingly, it is shown that the gender factor does not substantially influence the tax aggressiveness.
When peer norms work? Coherent groups facilitate normative influences on cyber aggression
Authors: Dang Jianning , Liu Li 
Published: August 2020

AbstractDue to the impersonal and anonymous nature of cyberspace, past work underscored the pivotal role of social influence processes in cyberbullying among adolescents. However, there was also evidence revealing the weak influences that some referent groups yield on youth. The current study argues that the strength of normative influences on cyberbullying depends on the properties of the referent groups. In the school context, we examined whether class entitativity—the extent to which a class is a unified and coherent group, rather than a mere aggregation of students—moderated the relationship between class norms and cyberbullying. A total of 474 adolescent students responded to measures of descriptive and injunctive class norms about cyberbullying, perceived class entitativity, and cyberbullying. The results indicated that pro‐cyberbullying descriptive and injunctive class norms were positively correlated with cyber aggression. Most importantly, higher levels of pro‐cyberbullying class norms predicted increases in cyber aggression when students perceived their classes as highly entitative. In contrast, this effect was not significant when students perceived their classes having low entitativity. These findings promote an understanding of how peer norms work and provide an alternative strategy for interventions into cyber aggression in schools.

A critical assessment of the potential for Structure‐from‐Motion photogrammetry to produce high fidelity 3D dental models
Authors: Silvester Christopher Martin , Hillson Simon 
Published: August 2020

AbstractObjectivesThe recent proliferation of methods of 3D model generation has enabled the development of new approaches to the analysis of dental form, function and wear. This article assesses whether Structure‐from‐motion (SfM) photogrammetry is capable of producing virtual 3D models of teeth of adequate quality for assessing fine scale surface details, such as dental macrowear patterns. Reference models were generated using a high resolution structured light scanner to assess the accuracy of the photogrammetric models generated.Materials and MethodsDental gypsum models of the molar teeth of human individuals from St. Michael's Litten, Chichester, Post‐medieval assemblage (n = 17) were used for 3D model generation. Photogrammetry was performed using Agisoft Metashape and reference 3D models were generated using a GOM ATOS 80 scanner. Focus stacking was explored as a method of enhancing 3D model detail. Differences between the photogrammetric and reference models were assessed using CloudCompare and the quality of the surface detail was examined quantitatively using Occlusal Fingerprint Analysis.ResultsPhotogrammetric model generation was highly replicable and the tooth models produced closely approximated the overall geometry of those derived from the structured light scanner. Dental wear facet area measurements on the photogrammetric models differed significantly, however, from those derived from the structured light scanning reference models.DiscussionPhotogrammetry can create virtual dental models from which crude quantitative size and shape data can be obtained. Finer scale surface details are not accurately reproduced on SfM models using the methods outlined in the current article due to high levels of surface noise.
Prevalence of internal carotid artery stenosis in ambulatory patients presenting for non‐emergent percutaneous coronary angiogram in a single Australian centre
Authors: O'Brien Andrew J. , Donlan John , Vrazas John I. 
Published: August 2020

AbstractIntroductionAssociation between coronary artery disease (CAD) and internal carotid artery stenosis (ICAS) could prove clinically relevant. However, evidence defining this association is currently inconclusive. Our study investigates the prevalence of ICAS in non‐emergent, ambulatory patients presenting for PCA with suspected CAD in an Australian context.MethodsBetween February 2019 and June 2019, 121 consecutive participants were verbally consented and enrolled in our study. The data were analysed retrospectively. PCA and CUS were performed within 24 h of each other. Multinomial logistic regression assessed independent predictors for ICAS, with statistical significance set at P value < 0.05. Linear regression analysis correlated CAD and ICAS severity, with significance of a P‐value < 0.05. Analysis was conducted using IBM SPSS 26 software (Chicago, Illinois).ResultsThe final study included 121 patients (age 73 ± 9 years, 76.9% male). ICAS on CUS was present in 55.4% of participants for PCA. CAD was an independent risk factor for ICAS on multinomial logistic regression odds ratio 3.87 (P = 0.023). CAD severity (multi vessel disease) showed significant correlation with ICAS r = 0.22 (P = 0.014) using linear regression analysis.ConclusionCAD is an independent predictor of ICAS, and severity of ICAS is correlated with CAD disease. However, most participants had only minor ICAS (16–49% diameter stenosis). Our findings are consistent with internationally published studies, suggesting their data are generalisable to the Australian population. Larger studies are needed to address the applicability of CUS screening in patients with advanced CAD.
Scaling Platinum‐Catalyzed Hydrogen Dissociation on Corrugated Surfaces

Published: August 2020

AbstractWe determine absolute reactivities for dissociation at low coordinated Pt sites. Two curved Pt(111) single‐crystal surfaces allow us to probe either straight or highly kinked step edges with molecules impinging at a low impact energy. A model extracts the average reactivity of inner and outer kink atoms, which is compared to the reactivity of straight A‐ and B‐type steps. Local surface coordination numbers do not adequately capture reactivity trends for H2 dissociation. We utilize the increase of reactivity with step density to determine the area over which a step causes increased dissociation. This step‐type specific reactive area extends beyond the step edge onto the (111) terrace. It defines the reaction cross‐section for H2 dissociation at the step, bypassing assumptions about contributions of individual types of surface atoms. Our results stress the non‐local nature of H2 interaction with a surface and provide insight into reactivity differences for nearly identical step sites.
