Waste glass as a precursor in alkali‐activated materials: Mechanical, durability, and microstructural properties

The long‐term characteristics and durability of alkali‐activated mortars based on waste glass are crucial to better understand their performance in aggressive environments. In this regard, the performance of waste glass as a building material and its characteristics such as mechanical (compressive, flexural, and tensile strengths), durability (chloride migration coefficient, sulfate resistance, and drying shrinkage), and microstructural properties [x‐ray diffraction (XRD), Fourier transform infrared (FTIR), and scanning electron microscopy (SEM) with energy dispersive x‐ray analysis (SEM/EDX)] were evaluated. For this purpose, the specimens with different amounts of silica modulus and Na2O content were prepared. The specimens were cured at 95°C for 20 h and then kept at a relative humidity of 50% at room temperature until testing. The specimen with 10% Na2O and a silica modulus of 1.5 demonstrated the highest compressive, flexural, and tensile strengths. The specimens illustrated a lower chloride migration coefficient and lower expansion than the Portland cement one. By increasing both silica modulus and Na2O contents, the drying shrinkage of the specimens increased due to the presence of more free water. The microstructural results indicated that amorphous gels such as sodium aluminum silicate hydrate (N‐A‐S‐H) and sodium (calcium) silicate aluminum hydrate [N‐(C)‐A‐S‐H] were formed. The results of this study signify the utilization possibility of waste glass as an eco‐friendly material with desirable characteristics.
Putting the Brakes on Autonomous Vehicle Control

The assimilation of automation in commuter vehicles is rapidly increasing, as too are the concerns with these technologies. Human interaction with autonomous vehicles must be thoroughly researched to understand the quantification and qualification of interactive behaviors with these systems. We developed a study using a high-fidelity driving simulator to mimic probable breakdowns with these systems to better understand the subsequent human responses and to explore the necessary technological requirements to overcome potential problems. 30 participants engaged in a driving scenario switching between manual and autonomous vehicle control. We accounted for individual differences in braking reaction time while simultaneously engaging in a secondary cognitive task during times of autonomous vehicle control. Results show the average RT for baseline scenarios without the cognitive task was 832.1 milliseconds while the average RT for baseline scenarios with the cognitive task was 908.4 milliseconds; a 9.17% significant increase. The average RT for the autonomous scenario was 1357.0 milliseconds; a significant increase of 49.38% over the baseline scenario with the cognitive task that can be attributed to the addition of automation. We found a positive linear correlation of time spent in autonomous control and subsequent braking reaction time. Additionally, cognitive task difficulty, attention allocation, self-reported mental demand, fatigue, and heart rate affect reaction time when cued to take control of the vehicle.
Significant Modulation of Vortex Resonance Spectra in a Square-Shape Ferromagnetic Dot

The resonance property of a magnetic vortex contained within a micron-sized square Py dot was detected using an amplitude-modulated magnetic field excitation technique. We found a significant modulation of the resonant spectra as the external magnetic field changes. The Lorentzian-like spectrum changes from a peak to a dip via a transition of anti-Lorentzian-like spectra. By conducting the micromagnetic simulations, we confirmed that the transition behavior results from the unusual resistance change depending on the vortex core center position. Additionally, the power dependence of the anti-Lorentzian-like spectra revealed a fairly persistent coexistence of peak and dip. Thus, the tunable spectra suggest one way to develop an integratable radiofrequency microcircuits.
Geometric control of an under-actuated balancing robot

Ball-balancing robots, or Ballbots, are under-actuated omni-directional mobile robots that balance on top of a single ball. The under-actuated nature arises from the fact that both position and attitude of the robot are actuated by the same actuators. This thesis introduces a geometric approach to the control of ball-balancing robots. In this approach, a new full 3D model is derived using screw theory. Based on this model, a geometric observer and geometric controller are proposed. Two methodologies are implemented, a computed torque controller and a sliding mode controller, that can track the attitude of the robot on either the special orthogonal group SO(3) or the 2-sphere S^2. Position control is achieved through the use of the relation between the desired linear acceleration and the attitude of the robot. The resulting desired attitude is tracked by one of the geometric attitude controllers. Simulation results show the effectiveness of the proposed controllers. The proposed sliding mode controller is shown to be more robust to model uncertainties. The position controller is shown to be able to control the position and follow trajectories, but overall global stability is not guaranteed. Recommendations are made to improve the performance. For the geometric observer, stability is shown under a set of assumptions. The work is concluded with a set of experiments on a real platform.
Uncovering the role of consumer trust and bandwagon effect influencing purchase intention: an empirical investigation in social commerce platforms

ABSTRACT Owing to the increased use of social media and networking, social commerce is gaining popularity among industry experts and academia. As a result, there are ongoing concerns about creating high-quality buyer-seller relationships in social commerce. To aid this conversation, the present research investigates the influence of several factors – mainly, social presence and trusting beliefs – on sellers’ trustworthiness. It also considers the impact of the bandwagon effect on purchase intention in the field of social commerce, as well as the role of gender differences in the relationship between trust and purchase intention. To validate the measures, the paper applied structural equation modeling to a data set of 204 online consumers in India. The study found that social bonding and bandwagon effect have a strong influence on trust and purchase intention, respectively. The results may encourage social commerce managers to develop better strategies for interacting and communicating with site users.
Correlation between hot carrier stress, oxide breakdown and gate leakage current for monitoring plasma processing induced damage on gate oxide

In this paper, we compare the HC stress and oxide breakdown results with the fast and commonly used gate leakage current measurement A clear correlation is found between low levels of gate leakage and both HC degradation and oxide breakdown. We, for the first time, demonstrate that the value of the gate leakage current is not only a failure indicator in the region about 1 nA but also a good indicator of the reliability of the devices in the region between 1 pA and 1 nA. Thus, from the value of gate leakage current one can estimate the reliability of the devices, saving precious measurement time.
Results from an international interlaboratory study on light‐ and elevated temperature‐induced degradation in solar modules

This paper reports the results of an international interlaboratory comparison study on light‐ and elevated temperature‐induced degradation (LETID) on crystalline silicon photovoltaic (PV) modules. A large global network of PV module manufacturers and PV testing laboratories collaborated to design a protocol for LETID detection and screen a large and diverse set of prototype modules for LETID. Results across labs indicate the reproducibility of LETID testing is likely within ±1% of maximum power (PMP). In intentionally engineered LETID‐sensitive modules, mean degradation after the prescribed detection stress is roughly 6% PMP. In other module types the LETID sensitivity is smaller, and in some we observe essentially negligible degradation attributable to LETID. In LETID‐sensitive modules, both open‐circuit voltage (VOC) and short‐circuit current (ISC) degrade by a roughly similar magnitude. We observe, as do previous studies, that LETID affects each cell in a module differently. An investigation of the potential mismatch losses caused by nonuniform LETID degradation found that mismatch loss is insignificant compared to the estimated loss of cell ISC, which drives loss of module ISC. Overall, this work has helped inform the creation of a forthcoming standard technical specification for LETID testing of PV modules, IEC TS 63342 ED1, and should aid in the interpretation of results from that and other LETID tests.
Association between CD8+ Tumor Infiltrating Lymphocytes and the Clinical Outcome of Patients with Operable Breast Cancer Treated with Adjuvant Dose-Dense Chemotherapy—A 10 Year Follow-Up Report of a Hellenic Cooperative Oncology Group Observational Study

Simple Summary Tumor-infiltrating lymphocytes (TILs) have been reported to contribute to breast cancer (BC) prognosis. The aim of our study was to investigate the prognostic impact of CD8+ TILs and their subtypes in patients with early breast cancer treated with sequential, dose-dense adjuvant chemotherapy. Tumors of 627 patients were examined for total (t), stromal (s), and intratumoral (i) CD8 lymphocyte density (counts/mm2). Our results showed that high expression of sCD8, iCD8, and tCD8 correlated with higher Ki67, TILs density, ER/PgR negativity, and higher histological grade. We confirmed that patients with high iCD8+ and tCD8+ TILs had longer DFS and OS, as compared to those with low counts/mm2. Survival benefit was retained when adjusting for classical clinical and pathological characteristics, but was not correlated to specific BC subtype. More data are needed to empower the prognostic role of TILs and establish their use in clinical practice. Abstract Tumor-infiltrating lymphocytes (TILs) contribute to breast cancer (BC) prognosis. We investigated the prognostic impact of CD8+ TILs in patients with early breast cancer treated with adjuvant chemotherapy in a large observational clinical trial. Along with a 10 year follow-up, considering the efficacy and safety, we report the results of the translational part of our study. We examined the patients’ tumors for total (t), stromal (s), and intratumoral (i) CD8 lymphocyte density (counts/mm2) on tissue-microarray cores. The impact of CD8+ TILs counts on DFS and OS, and its correlation with breast cancer subtypes and standard clinicopathological parameters, were investigated, along with efficacy and safety data. Among the 928 eligible patients, 627 had available CD8+ data. Of which, 24.9% had a high expression of sCD8, iCD8, and total CD8, which were correlated with higher Ki67, TILs density, ER/PgR negativity, and higher histological grade. The 5year DFS and OS rates were 86.1% and 91.4%, respectively. Patients with high iCD8 and tCD8 had longer DFS and OS compared to those with low counts/mm2 (DFS: HR = 0.58, p = 0.011 and HR = 0.65, p = 0.034 and OS: HR = 0.63, p = 0.043 and HR = 0.58, p = 0.020, respectively). Upon adjustment for clinicopathological parameters, iCD8 and tCD8 retained their favorable prognostic significance for DFS and OS, whereas high sCD8 was only prognostic for DFS. Menopausal status, tumor size, and nodal status retained their prognostic significance in all examined multivariate models. CD8+ TILs, and especially their intratumoral subset, represent a potential favorable prognostic factor in early BC.
A social media intervention for the families of young Black men with obstructive sleep apnoea

Objective: To address positive airway pressure (PAP) adherence in adolescents diagnosed with obstructive sleep apnoea (OSA) by pilot testing a novel, online, facilitated, peer-support and health education programme for families. Design, setting, and methods: Families participated in separate Facebook peer-groups (adolescent [n = 6] and parent [n = 6]) for 4 weeks, followed by face-to-face interviews. Participants received OSA and PAP educational videos and posts, engaged with questions and polls, and viewed de-identified postings of peer PAP use data. Results: Adolescent participants were young Black men aged 13–17 years (n = 6) with obesity (n = 5), severe sleep apnoea (100%) and 4–15 months of prior PAP use. Parent participants were mothers (n = 4) and fathers (n = 2). Four of six young men increased their mean PAP use during the intervention period. Overall, parents were more engaged with the Facebook group page than adolescents, but interviews revealed the online group/peer-support and education provided was highly regarded and appreciated by families. Parents were particularly appreciative of being involved in care and diagnosis in this way. Conclusion: Results of this pilot trial provide important data regarding intervention design, content and delivery approaches to be considered in the development of future interventions aiming to engage families and improve adolescent PAP adherence.
Religiosity dynamics among recently arrived Turkish marriage migrants in Germany

ABSTRACT Using mini-panel data from the SCIP (Causes and Consequences of Early Socio-Cultural Integration Processes among New Immigrants in Europe) project, this article contributes to the literature on marriage migration by investigating the dynamic role played by the religiosity of migrating partners. Specifically, we assess (1) how migrating partners differ from those who migrate for reasons other than marriage, in terms of their religiosity, to discuss the benefit system that the marriage migration offers to receiving partners and (2) how religiosity changes over the years for both migrating wives and husbands. Results from a series of linear mixed effects models reveal that, net of all controls, migrating wives are more likely to be religious than migrating husbands upon resettlement, as receiving husbands may prefer more traditional wives, and that receiving wives may prefer the opposite, to secure more self-dependence and power in the household. At the same time, it is found that migrating husbands become more religious than migrating wives two years after the resettlement, presumably as a way to reaffirm and restore their status loss as a result of various resettlement challenges and strain domestic relations. These findings suggest a nuanced image of the mechanisms behind marriage migration and religiosity.

Model-Based Iterative Reconstruction (MBIR) for ASPECT Scoring in Acute Stroke Patients Selection: Comparison to rCBV and Follow-Up Imaging

Background: To compare a model-based iterative reconstruction (MBIR) versus a hybrid iterative reconstruction (HIR) for initial and final Alberta Stroke Program Early Ct Score (ASPECT) scoring in acute ischemic stroke (AIS). We hypothesized that MBIR designed for brain computed tomography (CT) could perform better than HIR for ASPECT scoring. Methods: Among patients who had undergone CT perfusion for AIS between April 2018 and October 2019 with a follow-up imaging within 7 days, we designed a cohort of representative ASPECTS. Two readers assessed regional-cerebral-blood-volume-ASPECT (rCBV-ASPECTS) on the initial exam and final-ASPECTS on the follow-up non-contrast-CT (NCCT) in consensus. Four readers performed independently MBIR and HIR ASPECT scoring on baseline NCCT. Results: In total, 294 hemispheres from 147 participants (average age of 69.59 ± 15.63 SD) were analyzed. Overall raters’ agreement between rCBV-map and MBIR and HIR ranged from moderate to moderate (κ = 0.54 to κ = 0.57) with HIR and moderate to substantial (κ = 0.52 to κ = 0.74) with MBIR. Overall raters’ agreement between follow-up imaging and HIR/MBIR ranged from moderate to moderate (κ = 0.55 to κ = 0.59) with HIR and moderate to almost perfect (κ = 0.48 to κ = 0.82) with MBIR. Conclusions: ASPECT scoring with MBIR more closely matched with initial and final infarct extent than classical HIR NCCT reconstruction.
Determinants of Nutritional Differences in Mediterranean Rural Spain, 1840–1965 Birth Cohorts: A Comparison between Irrigated and Dry Farming Agriculture

Abstract Anthropometric studies have given much attention to the impact of industrialization and urbanization on the biological standards of living of urban populations. Instead, we know less about the evolution of height and the disparities within the rural world and how they have changed during the modern economic growth process. This article analyzes the evolution and the determining factors that would explain the inequality of the biological welfare of a group of rural populations in Mediterranean Spain. Using a database of the heights of military conscripts (N = 146,041) of the study area, a comparison is made of the biological well-being of the cohorts born between 1840 and 1965 in different rural environments (irrigated vs. dry farming). The results show that the recruits residing in irrigated areas were taller than those in dry farming areas and that the nutritional differences were greater among the latter. The advantage of the heights in irrigated areas widened with the development of commercial agriculture at the end of the nineteenth century and, although it began to reduce from the early decades of the twentieth century, the anthropometric gap persisted throughout the period analyzed. The data also suggest that the distribution of income was also more unequal in the dry farming areas, where the diet was less varied and rich than in the irrigated areas. This situation could be largely explained by the existence of low productivity agriculture in these dry farming areas, among other possible factors.
CD123 and More: How to Target the Cell Surface of Blastic Plasmacytoid Dendritic Cell Neoplasm

Simple Summary Until recently, there were no approved therapies for the aggressive blood cancer blastic plasmacytoid dendritic cell neoplasm (BPDCN). Survival for patients diagnosed with BPDCN is under two years, and improved treatments are needed. In 2018, tagraxofusp became the first approved drug for BPDCN. Tagraxofusp is an interleukin 3-dipththeria toxin recombinant fusion protein that targets CD123, a component of the interleukin 3 receptor, on the surface of BPDCN cells. Here, we discuss the development of tagraxofusp and other newer agents that also target CD123. We also present rationale for several other cell surface proteins, expressed on BPDCN, that are targets for therapies already in development for other cancers and that might be also considered for evaluation in BPDCN. Abstract Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare and aggressive leukemia derived from plasmacytoid dendritic cells (pDCs). It is associated with a remarkably poor prognosis and unmet need for better therapies. Recently, the first-in-class CD123-targeting therapy, tagraxofusp, was approved for treatment of BPDCN. Other CD123-targeting strategies are in development, including bispecific antibodies and combination approaches with tagraxofusp and other novel agents. In other blood cancers, adoptive T-cell therapy using chimeric antigen receptor (CAR)-modified T cells represents a promising new avenue in immunotherapy, showing durable remissions in some relapsed hematologic malignancies. Here, we report on novel and innovative therapies in development to target surface molecules in BPDCN currently in clinical trials or in preclinical stages. We also discuss new cell surface targets that may have implications for future BPDCN treatment.
Organizational Factors, ICT Support, and Affective Commitment: The Case of Bangladesh-Based Service Organizations

This paper investigates the influence of organizational factors on affective commitment, exploring the moderating role of information and communication technology (ICT) on their relationships. The study is based on empirical findings administered on 200 managerial personnel using the PLS-SEM. Team orientation, transformational leadership, transactional leadership and decentralization have a direct influence on affective commitment. The theoretical framework presented in this study focused on the integrated effect of organizational factors on affective commitment along with the moderating effect of ICT ICT support moderates the relationship between team orientation and affective commitment. The findings would provide managers an understanding of the factors influencing affective commitment in Bangladesh’s service organizations. The results indicate that ICT can be an effective tool to strengthen teamwork and employee commitment. Evidence from this study would help managers to to formulate strategies accordingly and provide new knowledge to researchers to look further into this field.
Money under the Mattress: Inflation and Lending of Last Resort

Central banks create money to lend during credit crunches, which might lead to inﬂation. We examine whether the two key functions of central banks— price stability and last-resort lending— conﬂict. We develop a nominal model of bank runs à la Diamond and Dybvig (1983) in which individuals can store the money they withdraw “under the mattress” or use it to buy assets. This feature allows for lending of last resort without creating inﬂation. Our analysis also provides a new rationale for the “Bagehot rule”: High interest rates prevent inﬂation, rather than mitigate the risk of lending during credit crunches.
