Chaotic dynamics in memristive circuits with different ϕ − q characteristics

There are two ideal memristive devices, first‐order memristor and second‐order memristor, which could be widely applied in nonlinear electronic circuits. The main difference between them is their ϕ − q characteristics. However, there are only a few studies available in the literature about the different dynamic behavior that can be observed when they are connected in the same circuit in turns. In this paper, to demonstrate the different consequences for the above situation, the complex dynamics of a memristive band‐pass filter (BPF) are analyzed in detail as one of the classical first‐order circuits. Also, the existence of coexisting attractors, hysteretic dynamics, and antimonotonicity are confirmed. Subsequently, the impact of memristor coefficients on the working dynamics of BPF is revealed. The conclusion is that a higher‐order memristor can lead to a greater number of chaotic attractors and more complex nonlinearity, which is the basis to determine that substitutability and interchangeability of equivalent memristance do not apply for memristor devices with the different ϕ − q relationship when analyzing memristive circuits. Finally, the experimental simulations are presented to further prove the above theoretical analysis. Additionally, other circuits, such as the Chua circuit and the Jerk circuit, are also investigated in order to verify our analysis. In particular, a full Feigenbaum tree is demonstrated in the Chua circuit.
Random Topology and Random Multiscale Mapping: An Automated Design of Multiscale and Lightweight Neural Network for Remote-Sensing Image Recognition

With the proposal of neural architecture search (NAS), automated network architecture design gradually becomes a new way in deep learning research. Due to its high capability regarding automated design, some pioneers have made an attempt to apply NAS in remote sensing and made some achievements, like 1-D/3-D Auto-convolutional neural network (CNN) and polarimetric synthetic aperture radar (PolSAR)-tailored Differentiable Architecture Search (PDAS). However, there are still some areas to be improved for existing NAS in remote-sensing field. In this article, we propose a random topology and random multiscale mapping (RTRMM) method to generate a multiscale and lightweight architecture for remote-sensing image recognition. First, a random topology generator generates the topology through random graph. Second, during the experiment, we find remote-sensing image features extracted by a multiscale network are more appropriate, compared with features extracted by a single-scale model. Nevertheless, the complexity inevitably increases with the introduction of a multiscale concept. Consequently, we design a variable search space consisting of decomposition convolution units under the guidance of mathematical analysis. The mapping of each neuron is then determined by a random multiscale mapping sampler. After that, we assemble the topology and mappings into blocks and construct three RTRMM models. Experiments on four scene classification datasets confirm the feature extraction capability and lightweight performance of RTRMM models. Moreover, we also observe that our approach achieves a better tradeoff between floating-point operations (FLOPs) and accuracy than some current well-behaved methods. Furthermore, the results on Vaihingen dataset verify the high feature-transfer capability.
Longitudinal trajectories of brain volume in combined antiretroviral therapy treated and untreated simian immunodeficiency virus-infected rhesus macaques

Supplemental Digital Content is available in the text Objectives: We used simian immunodeficiency virus (SIV)-infected nonhuman primates to investigate longitudinal changes of brain volume caused by SIV and the effect of combined antiretroviral therapy (cART). In addition, the relation between viral load, immune status, and brain volume were explored. Design: A longitudinal study of two healthy controls, five SIVmac239-infected macaques received cART (SIV+cART+) at 40 days postinnoculation, and five SIVmac239-infected macaques received no therapy (SIV+cART−). Methods: Structural T1-weighted MRI, blood and cerebrospinal fluid testing were acquired at multiple time points for 48 weeks postinfection (wpi). Brain volume was estimated using region of interest (ROI)-based analysis. Volume differences were compared among three groups. Linear regression models tested the associations between brain volumes and biomarkers (viral load, CD4+ T-cell count, CD4+/CD8+ ratio). Results: In our model, brain volume alteration in SIV-infected macaques can be detected at 12 wpi in several brain regions. As the infection progresses, the SIV+cART− macaques displayed generalized gray matter atrophy at the endpoint. Though initiate cART right after acute infection, SIV+cART+ macaques still displayed brain atrophy but showed signs of reversibility. Plasma viral load is mainly associated with subcortical nucleus volume whereas CD4+ T-cell count and CD4+/CD8+ ratio in plasma were associated with widespread cortical volume. Conclusion: The SIVmac239-infected Chinese origin macaque is a valid model for neuroHIV. Brain atrophy caused by SIV infection can be relieved, even reversed, by cART. Our model also provides new insights into understanding the pathogenesis of brain injury in people with HIV (PWH).
HybridTabNet: Towards Better Table Detection in Scanned Document Images

Tables in the document image are one of the most important entities since they contain crucial information. Therefore, accurate table detection can significantly improve information extraction from tables. In this work, we present a novel end-to-end trainable pipeline, HybridTabNet, for table detection in scanned document images. Our two-stage table detector uses the ResNeXt-101 backbone for feature extraction and Hybrid Task Cascade (HTC) to localize the tables in scanned document images. Moreover, we replace conventional convolutions with deformable convolutions in the backbone network. This enables our network to detect tables of arbitrary layouts precisely. We evaluate our approach comprehensively on ICDAR-13, ICDAR-17 POD, ICDAR-19, TableBank, Marmot, and UNLV. Apart from the ICDAR-17 POD dataset, our proposed HybridTabNet outperforms earlier state-of-the-art results without depending on pre and post-processing steps. Furthermore, to investigate how the proposed method generalizes unseen data, we conduct an exhaustive leave-one-out-evaluation. In comparison to prior state-of-the-art results, our method reduces the relative error by 27.57% on ICDAR-2019-TrackA-Modern, 42.64% on TableBank (Latex), 41.33% on TableBank (Word), 55.73% on TableBank (Latex + Word), 10% on Marmot, and 9.67% on UNLV dataset. The achieved results reflect the superior performance of the proposed method.
Microscopy and DNA‐based characterization of sinking particles at the Bermuda Atlantic Time‐series Study station point to zooplankton mediation of particle flux

Plankton‐derived, microscopic, and macroscopic sinking aggregates constitute most of the particulate organic carbon (POC) flux in the oceans. While the flux of particulate organic matter and associated elements has been quantified at the Bermuda Atlantic Time‐series Study (BATS) station for several decades, we lack an understanding of the source and composition of sinking particles, as well as the fate of predominant phytoplankton taxa. We determined the composition of individual sinking particles and their microbial communities in the upper 300 m depth at the BATS station in fall 2017 and spring 2018 by image analysis and V4 amplicon sequencing of the 16S and 18S rRNA genes. The sinking particles were primarily composed of phytodetrital aggregates, fecal aggregates, and fecal pellets. In the fall, phytodetrital aggregates were numerically dominant and drove the majority of the POC flux; however, in the spring, particle flux of all particle categories declined below 150 m, and the POC flux at 200 m shifted to one driven by fecal aggregates. The relative composition of the microbial communities associated with phytodetrital and fecal aggregates were statistically indistinguishable in both seasons, and prokaryotic taxa known to be associated with the gut microbiomes of zooplankton were indicators of the sinking particles. Our results point to the utilization and modification of sinking particles by resident midwater zooplankton populations, and to fecal pellets as the predominant mechanism transporting picophytoplankton to depth.
Does Diabetes Alter CSF Total Protein Levels? A Retrospective Cohort Study

Background and Purpose: Elevation of total protein level in cerebrospinal fluid (CSF-TP) in diabetic patients is often disregarded by clinicians. However, existing studies on the topic have significant limitations, and therefore we aimed to explore the relationship between diabetes and CSF-TP in a large database of CSF samples. Methods: Retrospective review of all diagnostic lumbar punctures at the Ottawa Hospital between 1996-2016. Patients were excluded if they had elevated CSF cell counts, or a condition known to elevate CSF-TP. Multivariate linear regression modeling considered the effects of age, sex, and diabetes. Results: Among 6124 patients (746 with diabetes, 5378 without), mean CSF-TP did not differ significantly between groups (0.39 and 0.35 mmol/L, p = 0.2). When controlled for age and sex, there was no significant effect of diabetes on CSF-TP and no significant correlation between mean serum glucose and CSF-TP (R2 = 0.12). Conclusions: CSF-TP did not differ significantly between diabetic and non-diabetic groups, once the influence of age and sex was controlled. Elevated CSF-TP should be regarded as pathologic, even in the setting of diabetes.
Mediating Role of Satisfaction with Life in the Effect of Self-Esteem and Education on Social Media Addiction in Turkey

The increasing use of social media due to various individual and social reasons may trigger some psycho-social issues. What can be effective in reducing social media addiction, which causes social and economic problems, is an important issue today. This study aimed to investigate the mediation effect of satisfaction with life in the impact of self-esteem and education level on social media addiction in individuals. The study was designed as cross-sectional, and the sample consists of 952 volunteers over the age of 15 using social media in Turkey. A personal information form, the Bergen Social Media Addiction Scale, the Rosenberg Self-Esteem Scale, and the Satisfaction with Life Scale were used as data collection tools in the study. The data were analyzed with SPSS 23.0 Program and PROCESS macro plug-in. Demographic questions such as age, gender, and marriage were used as control variables. As a result of the research, it was determined that satisfaction with life had a mediation role in the effect of self-esteem and education level on social media addiction. Self-esteem and education level improved satisfaction with life, and increased satisfaction with life resulted in less social media addiction. These results demonstrate the importance of implementing specific practices based on self-esteem and education, especially for vulnerable groups, to minimize the problems that may arise with the excessive use of digital apps and social media.
Immune response in Santa Inês sheep during Fasciola hepatica infection

In the present study, we describe the proliferative response and the IFN-γ, IL-10, IL-4 cytokine expression profiles in peripheral blood, and IgG production, after the experimental infection of Santa Inês sheep with 250 Fasciola hepatica metacercariae that were evaluated at 60 and 210 days post-infection(dpi). The cytokine expression profile at 60 dpi was characterized by the production of IFN-γ and IL-10, which is indicative of an initial mixed Th1/Th2 response. The modulation of the response occurred at 210 dpi with a predominance of IL-10 and IL-4 over IFN-γ. Mononuclear cells from peripheral blood stimulated with F. hepatica antigen exhibited proliferative capacity at 60 dpi, whereas the response was consistent with modulation from Th1 to Th2 in the chronic phase. The IgG antibody response was more marked at 60 days than at 210 dpi, confirming the mixed-response profile. The late modulation of the T lymphocyte response in association with the predominance of IL-10 and IL-4 at 210 dpi suggests the involvement of these cytokines after the establishment of the parasites in the bile ducts. The transition from a mixed to a regulatory response in the chronic phase was also accompanied by a reduced number of eggs per gram of feces.
Performances of Crossbred Chickens Fed Fermented Papaya Leaf and Seed Powder at High Stocking Density

The study evaluated the influence of fermented papaya leaf and seed powder (FPLS) and/or multienzymes on the growth, physiology, antioxidant, and gut ecology of the Indonesian crossbred chicken (ICC) at high stocking density. Three hundred and seventy ICC were randomly allotted to LSD (chicks fed conventional feed at low stocking density), HSD (chicks fed conventional feed at high stocking density), HSD+mE (chicks fed conventional feed plus multienzyme at high stocking density), HSD+FPLS (chicks fed FPLS at high stocking density) and HSD+FPLS+mE (chicks fed FPLS plus multienzyme at high stocking density). Body weight and feed intake were determined weekly. Two ICC were taken from each pen (10 chicks per treatment group) at week 10 for sampling. The study was arranged based on a completely randomized design with five treatment groups, each consisted of five replicates. Except for performance, analysis of variance was conducted on two chicks from each replicate (10 chicks per treatment group). Chicks in LSD consumed more (p<0.05) feed and had a higher (p<0.05) feed conversion ratio. Platelet distribution width (PDW) was lower (p<0.05) in HSD, HSD+FPLS, and HSD+FPLS+mE chicks than in LSD chicks. Lymphocyte counts were lower (p<0.05) in HSD relative to HSD+mE chicks. Superoxide dismutase (SOD) was higher (p<0.05) in HSD and HSD+FPLS+mE chicks than in LSD, HSD+mE, and HSD+FPLS chicks. High-density lipoprotein was smaller (p<0.05) in HSD+mE chicks than in LSD, HSD, and HSD+FPLS chicks. Compared to the other treatment groups of chicks, HSD+FPLS chicks had a lower (p<0.05) albumin level. Creatinine level was lower (p<0.05) in HSD chicks than in the other group of chicks. Enterobacteriaceae counts were lower (p<0.05) in HSD+FPLS cecal content of chicks than in LSD and HSD chicks. The redness values of breast meats were lower (p<0.05) in HSD+FPLS chicks than the chicks in HSD+mE and HSD+FPLS+mE dietary treatments. LSD chicks had higher (p<0.05) redness values of thigh meat than the other treatment groups of chicks. LSD chicks also had higher (p<0.05) yellowness values than HSD+mE and HSD+FPLS+mE chicks. In conclusion, high stocking density resulted in mild stress conditions, as was demonstrated by the increased SOD and decreased PDW and redness meat values. A combination of FPLS and multienzyme ameliorated the adverse influence of high stocking density in ICC.
Between Practice and Perception: Formative Assessment Used by EFL Novice Teachers and Students’ Responses toward the Implementation in Offline Classroom Mode

Abstract. This study aims to 1) investigate the ways of EFL novice secondary school teachers conducted Formative Assessment (FA) in offline classroom mode 2) investigate its implementation based on the five key strategies of FA 3) reveal students’ responses toward teachers’ implementation of FA in the classroom. The participants of this study were five EFL novice teachers and five students of several secondary schools in East Java, Indonesia. This study employed qualitative research and semi-structured interview to collect the data. Results showed that teachers use various ways to conduct the FA in the classroom, such as giving quizzes, observing the students’ attitudes, asking the students to make learning diary, and asking them to do self-assessment. It is also noted that the teachers employed the five keys strategies of FA, even though there is still a limitation found in the first strategy. Furthermore, students perceive the teachers’ implementation of FA both in positive and negative ways. Students also found that there are benefits of FA that they can grasp such as the awareness of their capability, as well as the sense of achievement that maybe helpful to grow their sense of responsibility to their learning experience.Keywords: EFL Classroom; EFL Novice Teachers; Formative Assessment; Students’ Perception
The effectiveness of 3D multiple object tracking training on decision-making in soccer

ABSTRACT Background Soccer requires athletes to make quick decisions in dynamic environments. Several off-court technology-based interventions have been developed to train these perceptual cognitive skills. However, the evidence for training transfer using technologies to athletic performance has been sparse. Previous research found 3-dimensional multiple object tracking (3D MOT) training to cause a significant increase in quality of passing decision-making. Limitations to the research warrant further investigation of this association. Purpose To re-examine the effectiveness of 3D MOT on training decision-making. Methods Thirty-one NCAA Division III soccer players (female n = 16) were randomized to 3D MOT training or a control task. The experimental group received 10 training sessions over a span of 4 weeks. Results The manipulation check indicated a significant training effect in 3D MOT performance for the intervention but not the control group (F(1,29) = 21.46, p < . 001, np 2 = . 43). Non-significant changes with small effect sizes (np 2 = .01-.03) in decision-making and measures of near-transfer were found. Conclusion The findings challenge the association between 3D MOT training and increased quality of decision-making in soccer.
Study of the Antimicrobial Effect of an Ethanolic Extract of Propolis in Periodontal Disease

Periodontal disease encompasses gingivitis and periodontitis and is one of the most common chronic infections in the adult population. This study aimed to evaluate the influence of Spanish propolis extract (EEP) on the effect of the clinical and microbiological parameters as an adjuvant to scaling and root planning in patients undergoing supportive periodontal therapy (SPT). Forty chronic periodontitis patients were randomly assigned into two groups for the treatment. In the control group (n = 20), the sites were treated by scaling and root planing followed by gingival irrigation with physiological saline and in the test group (n = 20), the sites were treated by scaling and root planing followed by subgingival placement of EEP. At baseline (BL), bleeding on probing positive (BOP+) sites with probing pocket (PPD) ≥ 4 mm were defined as study sites. Plaque index, PPD, BOP, clinical attachment level (CAL), and subgingival plaque were evaluated at BL and 1 month later. The results showed a significant clinical improvement (p < 0.05) in the PPD, CAL and BOP+ comparing them with BL and one month after the periodontal treatment and a significant reduction (p < 0.05) for Tannerella forsythensis, Porphyromonas gingivalis, Prevotella intermedia and Treponema denticola in both groups. In addition, the improvement of clinical parameters was observed with subgingival use of EEP and also statistically significant differences between groups were observed (p < 0.05) such as reductions of BOP+ % and reduced counts of T. forsythensis and P. gingivalis, considered as the “key pathogens” for the periodontal diseases. Our results suggest prophylactic and therapeutic potential for EEP against periodontal diseases, improving clinical parameters, reducing gingival bleeding and decreasing bacterial counts of T. forsythensis and P. gingivalis. The subgingival use of EEP represents a promising modality as an adjuvant in periodontal therapy to avoid microbial resistance and other adverse effects.
Robert Torrens and the dynamics of wages in a growing economy

Abstract In 2018, Taro Hisamatsu published in this journal a reconstruction of the dynamic theory of economic growth that Torrens developed in On the Means of Improving the Condition of the Labouring Classes (1829). However, on a couple of important issues—the exogeneity and constancy of the minimum of wages; and the tendency of population to increase faster than capital—, Hisamatsu’s model appears to be at variance with Torrens’s genuine point of view. The aim of my paper is then to provide an alternative to Hisamatsu’s reconstruction of Torrens’s dynamic vision of a growing economy.
Asexuality and epistemic injustice: a gendered perspective

ABSTRACT Drawing on original qualitative research, I argue that the concept of ‘epistemic injustice’ proposed by the feminist philosopher Miranda Fricker, and located within a long genealogy of Black feminist scholarship, can be used sociologically to help understand the lived experiences of asexual people. I show how participants’ accounts of their asexual subjectivities were frequently denied, dismissed and over-written. However, I argue that these experiences were heavily gendered, in that asexual women were subject to epistemic injustices to a degree and in ways that their male counterparts were not, and that this must be understood within the power relations of hetero-patriarchy. These epistemic injustices revolved around old yet prevailing constructions of femininity and womanhood as ‘naturally’ asexual, passive, and lacking agency. When asexual men experienced epistemic injustice, this was rooted in familiar understandings of masculinity as necessitating an active and desiring sexuality. Using Fricker’s elucidation of hermeneutical and testimonial forms of epistemic injustice, I show how asexuality remains a culturally unfamiliar hermeneutical frame in a context of ‘compulsory sexuality’ but also how stories of asexuality are ‘heard’ based on the gendered (and unequal) distribution of testimonial credibility.
New evidence for active talus-foot rock glaciers at Øyberget, southern Norway, and their development during the Holocene

Synthetic aperture radar interferometry (InSAR) measurements demonstrate that lobate, blocky depositional landforms, located in southern Norway at an altitude of ~530 m above sea level, with an estimated mean annual air temperature of ~1.6°C, currently exhibit deformation attributed to viscous creep. Five years of InSAR measurements for six lobes demonstrate average surface velocities of 1.2–22.0 mm/year with maximum rates of 17.5–55.6 mm/year. New Schmidt-hammer exposure-age dating (SHD) of two proximal lobes reveals mid-Holocene ages (7.6 ± 1.3 ka and 6.0 ± 1.2 ka), which contrast with the early-Holocene SHD and 10Be ages obtained previously from distal lobes, and late-Holocene SHD ages presented here from two adjacent talus slopes (2.3 ± 1.0 ka and 2.4 ± 1.0 ka). Although passive transport of boulders on the surfaces of these small, slow-moving rock glaciers affected by compressive flow means that the exposure ages are close to minimum estimates of the time elapsed since lobe inception, disturbance of boulders on rock glaciers is a source of potentially serious underestimates of rock-glacier age. Rock-glacier development at Øyberget began shortly after local deglaciation around 10 ka before present and continued throughout the Holocene in response to microclimatic undercooling within the coarse blocky surface layer of the talus and rock-glacier lobes. We suggest this enhanced cooling lowers mean annual surface-layer temperature by at least ~3.6°C, which is needed at such a low altitude to sustain sporadic permafrost and avoid fast thawing as atmospheric temperatures rise. Our results point to circumstances where inferences about rock glaciers as indicators of regional climate should be interpreted with caution, and where they may be less useful in palaeoclimatic reconstruction than previously thought.
