Trustworthy Network Anomaly Detection Based on an Adaptive Learning Rate and Momentum in IIoT

While the industrial Internet of Things (IIoT) brings convenience to the industry, it also brings security problems. Due to the massive amount of data generated by the surge of IIoT devices, it is impossible to ensure whether these data contain an attack or untrustworthy data, therefore, how to ensure the security and trustworthiness of IIoT devices has become an urgent problem to solve. In this article, we design a new hinge classification algorithm based on mini-batch gradient descent with an adaptive learning rate and momentum (HCA-MBGDALRM) to minimize the effects of security attacks. The algorithm significantly improves the performance of deep network training compared with traditional neural networks, decision trees and logistic regression in terms of scale and speed. In addition, we have solved the data skew problem in the shuffle phase, and we implement a parallel framework for HCA-MBGDALRM to accelerate the processing speed of very large traffic data sets.
Vision based Chang’E-4 landing point localization

On December 8, 2018, China launched the Chang’E-4 lunar probe and implemented soft landing and patrol exploration on the lunar farside for the first time. Fast and high-precision positioning of the landing point is a critical step of the mission, and also an important prerequisite for surface operations of the lander and rover. Based on the high-precision image matching and geometric transformation methods, and considering the engineering requirements, the landing point location of the Chang’E-4 lander was initially determined using the near real-time high compression ratio descent sequence images. Then, the position was refined using the replayed low compression ratio descent images, and the landing point position was calculated to be (177.5884°E, 45.4565°S). The landing point localization method and result have been successfully applied to actual engineering tasks for the first time in China, thus providing important support to the topographic analysis of the landing area and mission planning of the follow-up teleoperations.
The students’ career development association in a Chinese university: A qualitative study

This qualitative study investigated key features of the Students’ Career Development Association (SCDA) in a Chinese mainland university. This university has been recognized for its pioneering achievements in career guidance. The operations and development of the SCDA were explored to determine how career guidance provided by the association enhances students’ career competencies. Results provided a paradigm that other universities could use for reference when developing career guidance services operated by students. The study contributes to the exploration of career guidance in university contexts.
Using multiple character strengths to inform young adults’ self-compassion: The potential of hope and forgiveness

ABSTRACT Self-compassion is an adaptive means of relating to the self during times of distress. Character strengths include a set of traits and values that ultimately uplift the self and others. Although self-compassion is known to be associated with multiple character strengths, there remain opportunities to address whether particular strengths uniquely inform individual differences in self-compassion. Using three studies, strengths of curiosity, grit, gratitude, hope, and forgiveness were considered to determine which strengths provided unique information for reports of self-compassion. Results showed that hope and forgiveness were robustly associated with self-compassion when these strengths were studied simultaneously (Studies 1 and 2) and alongside Big Five covariates (Study 2). Study 3 showed that the effects of hope and forgiveness on self-compassion were comparable between college- and community-recruited young adults. Overall, findings suggest that hope and forgiveness may be promising targets to further understand, and ultimately promote, self-compassion.
Prophets, pastors and profiteering: exploring external providers’ enactment of pastoral power in school wellbeing programs

ABSTRACT This paper explores the governance practices that external providers of school wellbeing programs employ in their contribution to the subjectification function of education. In neoliberal times where this ‘game’ of subjectification has become more open, governmentality scholars have been challenged to provide more robust insight into how discourses permeate individual subjectivities. In response, we draw on recent theorising of Foucault's pastoral power concept and a resulting analytic framework of four interlinked practices to explore external providers’ endeavours to ‘shepherd’ students, teachers and parents in the practices and responsibilities of personal wellbeing. Our data revealed that discourse tension and conflict emerges within school communities’ increasingly ‘messy’ pastoral terrain. In conclusion, we suggest that more empirical and theoretical insight into actors’ resistance and agency within the pastoral power landscape of schools offers a vital contribution to our understanding of external providers’ influence on education policy and enactment.
'Het zit allemaal tussen mijn oren!': De neuropsychologie van verslavingsproblematiek bij mensen met een lichte verstandelijke beperking ['It's all between my ears!': The neuropsychology of substance use disorders in individuals with mild to borderline intellectual disability]

Verslavingsproblematiek gaat gepaard met allerlei neuropsychologische veranderingen in de hersenen. Dit artikel presenteert de conclusies van een onderzoeksproject gericht op deze veranderingen bij problematische drinkers met een lichte verstandelijke beperking (LVB). Gebaseerd op dit onderzoek wordt het gebruik van indirecte maten (zoals computertaken) voor klinische doeleinden afgeraden. Het verdient aanbeveling om vroeg in het behandeltraject een uitgebreid neuropsychologisch onderzoek te doen en het behandeltraject hierop aan te passen. De complexiteit van verslavingsproblematiek bij deze doelgroep vraagt om een gespecialiseerde aanpak, waarbij kennis van de LVB en van verslavingsproblematiek noodzakelijk is. Samenwerking tussen verstandelijk-gehandicaptenzorg en verslavingszorg is daarom essentieel. Dit artikel is een bewerking van Van Duijvenbode et al. (2016). 'Het zit allemaal tussen mijn oren!

Is the Taylor rule optimal? Evaluation using a wavelet-based control model

ABSTRACT This paper extends the wavelet-based control (WBC) model of Crowley and Hudgins (2015) to compare the simulated performance of jointly optimal fiscal and monetary policy, where the policymakers place emphasis on a variety of macroeconomic targets, with the case where monetary policy follows a modified Taylor rule. The results show that the Taylor rule is likely to render higher interest rates, diminished investment, and appreciated real exchange rates compared with an unconstrained baseline simulation. We therefore find that the Taylor rule is suboptimal since it results in higher fiscal deficits due to substitution by policy authorities, thus confirming recent research on the interaction of fiscal and monetary policies. The analysis also compares the baseline and Taylor rule simulated forecasts when the central bank adopts a ‘hawkish’ inflation policy compared to a more ‘dovish’ policy stance.
Making health social: Effects of health PSA videos on social media

In the digital age, social networking sites are an essential tool for health educators to promote and spread awareness about health issues that may be plaguing society. Internet communications, such as social media, offer tremendous opportunities for modifying health because it allows people of all demographics to access health information. The present study examined the effectiveness of health public service announcement (PSAs) videos on social media and examined how the heuristics of social media “likes” may play a role in how social media users perceive these health messages. To assess how health messages on social media are perceived, this thesis used an experimental design (N = 272). This study could not find statistical support for the hypotheses that subjects were likely to show more favorable attitudes, self-efficacious behaviors, perceived norms, or intentions when exposed to health messages that displayed a high amount of social media “likes. ” Results indicated, however, that attitudes (F(1, 270) = 162.38, p < . 001) perceptions of selfefficacy (F(1, 270) = 347.69, p < . 001), and perceived social norms (F(1,270) = 139.25, p < . 001) were related to intentions to exercise, as predicted by the Theory of Planned Behavior. The results of this study indicate that health messages in the context of social media are extremely complex, and deserve future attention in literature.

Estimation of Genetic Diversity in Seven Races of Native Maize from the Highlands of Mexico

Characterizing the genetic diversity of maize (Zea mays L.) populations by their morphological and molecular attributes makes it possible to place populations into specific groups; thus, facilitating the design of procedures for their optimum and sustainable use. In this study, data from two lines of evidence were analyzed simultaneously to robustly classify maize populations and to determine their genetic relationships. Seven maize races of the central high plateau of Mexico were characterized using a combined analysis of 13 morphological traits and 31 microsatellite loci. The germplasm assessed included samples of 119 accessions held at Mexican germplasm banks. Cluster and principal component analyses were performed. Also, genetic and geographic relationships among the accessions were determined. Principal component analysis separated the different accessions into well-defined groups using first three principal components. The accessions of Arrocillo Amarillo and Elotes Conicos races did not exhibit a grouping pattern, indicating greater genetic complexity. Better grounded grouping and phylogenetic relationships were obtained when traits of both lines of evidence were used simultaneously.

Simulation-based Investigation on Massive Multi-Antenna System as to Spatial Channel Hardening for Mobile Single User in a Controlled Multipath Environment

This paper brings up the concept of spatial hardening of massive MIMO radio channel in a controlled multipath cavity. The motivation is that, for a mobile user being active in certain area, the massive multi-antenna system shall guarantee the channel hardening in that area. This paper simulates the radio channel confined in a controllable indoor cavity using ray tracing, where the propagation environment contains reflecting and absorbing walls. The multipath channels composing of direct paths and specularly reflected paths up to a second order are analyzed as function of the large scale array topology and configuration in the cavity. We analyze the area focusing performance using a novel spatial channel hardening metric. This study is instructive for massive MIMO system design targeting at steadily hardened channel in an area for user with mobility. Different from the existing work on “separability of close users” and “serving dense users”, this paper is to understand the spatial focusing and spatial hardening, as well as how different antenna topologies impact both under different multipath conditions.
A fractional-order model on the dynamic mechanical behavior of magnetorheological elastomers

In order to describe the dynamic behavior of magnetorheological elastomers (MREs) for the realization of vibration control, this study proposes a constitutive model containing a fractional element and nonlinear springs attributed to the viscoelastic and the rheological properties, respectively. The viscoelastic behavior in various magnetic fields was studied experimentally to develop this fractional-order nonlinear model, and the model parameters were identified through experimental data fitting of dynamic modulus in frequency domain. The model predictions were subsequently obtained with the predictor-corrector approach to validate the proposed model by comparing with the experimental results on the stress-strain hysteresis. In addition, the efficiency of the proposed model of MRE was also evaluated by comparing the numerical solution with the results of the revised Bouc–Wen model.
Refractive meridional corneal collagen cross-linking: a new modified technique for treatment of astigmatism

Purpose The aim of the study was to evaluate the efficacy and safety of using corneal collagen cross-linking as a refractive procedure to correct corneal astigmatism. Setting This study was conducted in Sohag University Hospital (Egypt). Design This is a prospective, nonrandomized, clinical trial study. Patients and methods Fifteen eyes of 11 patients complaining of astigmatism were treated with refractive meridional cross-linking (RMCXL). Group A included eight eyes that had undergone previous cross-linking and implantation of intracorneal rings that failed to correct the astigmatic component of keratoconus. Group B included seven eyes with astigmatism without corneal ectasia. All eyes were subjected to examination of the preoperative and postoperative uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), and manifest refraction, as well as slit lamp examination of the anterior segment, keratometry, and pachymetry by corneal topographies at 1 week and at 1, 3, and 6 months′ follow-up. Results In group A, the preoperative mean UDVA was 0.90 ± 0.33 (log MAR ± SD), whereas the postoperative mean UDVA was 0.78 ± 0.27. The preoperative mean CDVA was 0.60 ± 0.38, whereas the postoperative mean CDVA was 0.48 ± 0.26. The mean postoperative astigmatic correction was 1.8 ± 0.36. In group B, the preoperative mean UDVA was 0.78 ± 0.53, whereas the postoperative mean UDVA was 0.52 ± 0.23. The preoperative mean CDVA was 0.52 ± 0.26, whereas the postoperative mean CDVA was 0.30 ± 0.15. The mean postoperative astigmatic correction was 0.90 ± 0.29. Conclusion RMCXL showed good refractive correction for astigmatism in both ectatic and nonectatic corneas. RMCXL proved to be a promising new simple, effective, and safe procedure for the treatment of corneal astigmatism with reasonable patient satisfaction.
Teaching practices for differentiating mathematics instruction for middle school students

ABSTRACT Three iterative, 18-episode design experiments were conducted after school with groups of 6–9 middle school students to understand how to differentiate mathematics instruction. Prior research on differentiating instruction (DI) and hypothetical learning trajectories guided the instruction. As the experiments proceeded, this definition of DI emerged: proactively tailoring instruction to students’ mathematical thinking while developing a cohesive classroom community. Analysis of 10 episodes across experiments yielded five teaching practices that facilitated DI: using research-based knowledge of students’ mathematical thinking, providing purposeful choices and different pathways, inquiring responsively during group work, attending to small group functioning, and conducting whole class discussions across different thinkers. The latter three practices, at times, impeded DI. This study is a case of using second-order models of students’ mathematical thinking to differentiate instruction, and it reveals that inquiring into research-based knowledge and inquiring responsively into students’ thinking are at the heart of differentiating mathematics instruction.
Off-policy Bandits with Deficient Support

Learning effective contextual-bandit policies from past actions of a deployed system is highly desirable in many settings (e.g. voice assistants, recommendation, search), since it enables the reuse of large amounts of log data. State-of-the-art methods for such off-policy learning, however, are based on inverse propensity score (IPS) weighting. A key theoretical requirement of IPS weighting is that the policy that logged the data has "full support", which typically translates into requiring non-zero probability for any action in any context. Unfortunately, many real-world systems produce support deficient data, especially when the action space is large, and we show how existing methods can fail catastrophically. To overcome this gap between theory and applications, we identify three approaches that provide various guarantees for IPS-based learning despite the inherent limitations of support-deficient data: restricting the action space, reward extrapolation, and restricting the policy space. We systematically analyze the statistical and computational properties of these three approaches, and we empirically evaluate their effectiveness. In addition to providing the first systematic analysis of support-deficiency in contextual-bandit learning, we conclude with recommendations that provide practical guidance.
Nutritive value of sugarcane silages with different bacterial additives and fermentation periods

ABSTRACT The objective of this study was to evaluate the nutritive value of sugarcane silage with or without inoculation with P. acidipropionici or L. buchneri, over three fermentation periods. The experimental design was completely randomized in a 3 x 3 inoculant by fermentation period factorial arrangement (without inoculant, inoculant 1, inoculant 2; x three fermentation periods, 10, 60, 90 days). Values of pH, dry matter (DM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), hemicellulose (HEM) and lignin were determined and in situ DM degradability profiles were modelled for parameters a, b and c, potential degradation (A) and effective degradability (ED). The 90 day fermentation yielded a lower pH for both inoculants. There was an interaction between inoculant and fermentation period (P < 0.05) for DM content, with a reduction in silage DM without the additive at 90 days. The CP, HEM, ADF and lignin contents of sugarcane were not influenced by the treatments. The addition of P. acidipropionici provided the lowest NDF content at 10 days and presented a higher fraction a, potential degradation and ED. At 60 days, there was no variation in soluble fraction, the control silage showed a higher fraction b, higher potential degradation and ED. At 90 days of fermentation, L. buchneri silages presented a higher fraction a, degradation rate and DE and a higher b value was obtained in the silage without inoculant. Inoculants are effective in maintaining the silage DM content and nutritional value during prolonged fermentation periods.
Toward a better understanding of the relationship between influenza vaccine efficacy against specific and non-specific endpoints and vaccine efficacy against influenza infection

In influenza vaccination studies assessing vaccine efficacy (VE), both specific and non-specific endpoints (outcomes) are used. We present a formula for the relationship between VE against influenza-related outcomes (VEO), specific and non-specific, and that against influenza infection (VEI). In its simplest form, the formula comprises two additional parameters: the influenza attack rate among unvaccinated subjects, and the relative risk of the outcome for influenza infected subjects versus non-infected subjects. Both parameters may show large between-seasonal variation, which translates to a large between-seasonal variation of VEO estimates. With the full form of the formula it can be shown that, contrary to popular believe, VEO may be greater than VEI. We argue that interpreting VEO estimates in terms of “low” or “high” is not possible without taking the costs of an outcome case into account. We conclude that the decision to use a non-specific endpoint as surrogate for influenza infection should be taken in the awareness of these limitations.

The role of Pim-1 in breast cancer metastasis

Breast cancer is the most common cancer in women. Despite advances in treatment options, the spread of breast cancer to distant organs (metastasis) remains the major cause of morbidity and mortality in breast cancer patients. This is attributed primarily to the impairment of function in affected organs. Thus, there remains a vital need for better-targeted treatments that more effectively inhibit the development or progression of metastases. Pim-1 is a serine/threonine survival kinase that has been implicated in the development of metastasis in several haematological and solid cancers. However, little is known about its role in breast cancer. In our laboratory, we previously identified Pim-1 as upregulated in brain metastatic 4T1Br4 syngeneic mouse cells and tumours compared to parental 4T1 cells. This led us to propose that Pim-1 may play a role in mediating breast cancer brain metastasis. Therefore, the overall objective of this project was to examine the expression and functional role of Pim-1 in breast cancer metastasis, with a focus on organspecific metastasis. We interrogated public databases to show that Pim-1 expression is low to absent in normal breast tissue and increased in breast tumour tissue. Furthermore we show that the murine (4T1Br4) and human (MDA-MB-231Br) brain metastatic breast cancer cell lines and tumours demonstrate the highest expression of Pim-1 mRNA and protein. To investigate the function of Pim-1 in breast cancer metastasis we tested the impact of inhibiting Pim-1, either by gene knock down using short hairpin RNAs or the pharmacological inhibitor SGI-1776, on the ability of 4T1Br4 and MDA-MB-231Br cells to migrate and invade in vitro. 4T1Br4 cells displayed increased migration and invasion propensity after Pim-1 knock down and this was coupled with a decrease in β4 integrin expression. Conversely, MDA-MB231Br cells showed a decreased ability to migrate and invade after Pim-1 KD, as well as decreased cell surface expression of β1 and β3 integrins.
