Nonwoven composite endowed with electromagnetic shielding performance by graphene nanosheets adherence

Abstract A nonwoven-based composite that can shield electromagnetic interference (EMI) in contemporary society was successfully fabricated by adhering graphene (GE) nanosheets to nonwoven fabric with polyvinylidene fluoride (PVDF) as the adhesive agent. A cyclic GE dispersion dipping-drying process produced nonwoven composites with increasing GE adsorption, which formed an ever more conductive network and led to improvement in EMI shielding performance. The bonding effects of PVDF between GE nanosheets and nonwoven framework were confirmed via ultrasonic vibration analysis and morphology observation. Composite shielding effects were evaluated in a wide incident frequency from 1 to 18 GHz, which revealed that the overall EMI shielding effectiveness was over 20 dB and this EMI shielding was absorption dominant. Such a composite possessed the potential to be used in household and industrial products for EMI shielding.
Charge Transport in a Quantum Dot Supercrystal

Colloidal semiconductor quantum dots connected by organic or inorganic molecules can form periodic supercrystals. These supercrystals can be used for various types of electronic and optical applications with properties superior to those of random quantum dots and organic polymer mixtures. We have used ab initio calculations to study the charge transport and carrier mobility in such supercrystals. Among the different possible charge transport mechanisms, we found that the phonon-assisted hopping is the most likely mechanism. The calculated carrier mobility agrees well with the experimentally measured results. Our predictions of the size and temperature dependences on the mobility are awaiting experimental confirmation.

Safety and efficacy of VIP152, a CDK9 inhibitor, in patients with double-hit lymphoma (DHL).

Background: PTEFb/CDK9-mediated transcription of short-lived anti-apoptotic survival proteins and oncogenes like MCL-1 and MYC plays a critical role in a variety of cancers. VIP152 (formerly BAY 1251152), a potent and highly selective CDK9 inhibitor, has been evaluated in a Phase 1 dose-escalation study in patients with advanced cancer. The maximum tolerated dose was 30 mg once weekly administered in consecutive 21-day cycles, based on neutropenia as the dose-limiting toxicity (JCO 2018;36:2507;NCT02635672). DHL is defined as dual rearrangement of the MYC gene and either the BCL2 or BCL6 genes;the resulting overexpression of MYC and BCL2/BCL6 make it particularly difficult to treat. Patients with DHL have a poor prognosis and no standard of care. Considering the impact of CDK9 inhibition on MYC, an exploratory cohort of patients with DHL was added to the study. Methods: Patients with refractory or relapsed DHL were eligible. VIP152 was administered once weekly as a 30-minute IV infusion on Days 1, 8 and 15 of a 21-day cycle. Tumor response was assessed according to the revised Cheson criteria (2007). Results: To date a total of 7 patients have been enrolled and were evaluable at the time of data cutoff (24NOV2020). The patients were mostly men (6/7 pts, 86%) with a median (range) age of 70 (58-84) years. All patients received ≥2 prior therapies, including 2 patients with bone marrow transplant. Three of 7 patients (29%) had ≥3 prior therapies. The median time on treatment was 22 days (range 8-1361 days). The most common adverse events of any grade were: constipation, fatigue, nausea (each 3/7 pts, 43%) and abdominal pain, diarrhea, lymphocyte count decrease, neutrophil count decrease, skin infection, tumor pain, and vomiting (each 2/7 pts, 29%). Most were Grade 1 and Grade 2. The Grade 3 adverse events were fatigue, lymphocyte count decrease, neutrophil count decrease (each 1/7 pts, 14%) and tumor pain (2/7 pts, 29%). One Grade 4 lymphocyte count decrease was reported. Two patients had a serious adverse event (Grade 3 syncope and Grade 3 tumor pain). Two patients had dosing held for an adverse event;however, no patient withdrew from treatment due to any adverse events. One death occurred due to disease progression. Pharmacodynamic biomarker analysis showed significant reduction of MYC, PCNA, and MCL-1 mRNA in all patients across multiple timepoints. Antitumor activity consisted of 2 complete metabolic responses in 7 patients (29%) based on investigator-assessed FDG-PET scans. Due to the COVID pandemic, the patients withdrew consent after 3.7 and 2.3 years, respectively, of treatment. Both patients were in complete metabolic response. Conclusions: VIP152 had a manageable safety profile, on-target pharmacodynamic activity and signs of durable monotherapy antitumor activity in patients with DHL. These encouraging results warrant further evaluation of VIP152 in patients with MYCdriven lymphoma and solid tumors.
Evaluation of Some Chemical and Sensory Properties of Processed Cheese Analogue with Selected Vegetable Oils

Cheese analogues are cheese-like products with varied compositions and functional properties which produced by partial or whole replacement of milk components, in particular milk fat, by non milk-based components. The purpose of this research was to evaluate the effect of replacement of milk fat in processed cheese with different formulations from olive, corn and sesame oils on some chemical and sensory properties. The results indicated that the peroxide values were not affected by the replacement of milk fat with vegetable oils significantly (P
Pyrolysis of Monodisperse Poly-α-Methylstyrene.

Pyrolysis of monodisperse poly-α-methylstyrene of wide molecular weight range (M:25,000-5,000,000) was studied isothermally under vacuum in the temperature range 240-280 °C. Thermogravimetric analysis was used for measuring the rate of degradation, and gel permeation chromatography for analyzing the molecular weight and molecular weight distribution as a function of conversion. The initial rate of monodisperse poly-α-methylstyrenes, and the deuterated samples (poly-α-trideuteromethyl-β, β-dideuterostyrene) increases with increasing molecular weight. At molecular weight higher than 1 × 106, the initial rate continues to increase almost linearly instead of being constant as concluded from earlier work. The molecular weight distribution ratio, M w /M n , increases as a function of conversion and approaches the most probable distribution. The results conform to a degradation mechanism with random initiation. The curves of initial rate as a function of molecular weight lead to higher zip lengths than previous estimates. Attempts at simultaneous estimation of zip length and transfer constant from the rate and molecular weight data led to inconsistent results. If the variation of termination rate with molecular weight plays a role, this variation must be less than that derived naively from melt viscosity. Bimodal molecular weight distributions were not found.
Comparison and modification of survival predicting system for breast cancer patients with bone metastases

Background: Breast cancer is the most common malignancy in the female. Survival for patients with breast cancer has improved substantially over the past two decades, accompanied by increased patients with skeletal-related events. Since surgery is most commonly needed for complete or pending pathological fractures, an accurate preoperative survival estimation for patients with symptomatic bone metastases is crucial in surgical decision making. Several prognostic models for survival estimation in metastatic cancer patients have been developed in western centers without external validation in Asian patient populations and breast cancer-specific cohorts. Methods: Seven survival prediction models were externally validated by a cohort of metastatic breast cancer patients from an Asian center. The prediction ability and accuracy were valued using receiver operating characteristic analysis and Brier score at different time points. Univariate and multivariate Cox regression was used to identify independent prognostic factors. A multivariable prediction model was further established and validated. Results: In our metastatic breast cancer patients cohort, the PathFx model demonstrated superior accuracy at predicting 3- and 6-month survival while the SSG model showed the highest accuracy at 12-month. None of these models exhibit accurate predictions beyond 12-month. Cox regression further identified five independent prognostic factors. A prognostic scoring system with breast cancer-specific prognostic factors was established. Internal validation showed consistent discrimination and accuracy. Conclusions: Current prognostic models showed inconsistent and limited accuracy in Asian metastatic breast cancer patients, especially for more prolonged estimated survival. A disease-based predicting model with cancer-specific prognostic factors would increase the prediction accuracy and help with surgical decision making.
Liquid Oxygen / Liquid Methane Testing of the RS-18 at NASA White Sands Test Facility

A ground test article was prepared for RS-18 engine testing using liquid oxygen (LO2) and liquid methane (LCH4) propellants under simulated altitude conditions at NASA Johnson Space Center White Sands Test Facility (WSTF). This project is part of NASA Glenn Research Center’s Propulsion and Cryogenics Advanced Development (PCAD) project. "Green" propellants, such as LO2/LCH4, offer savings in both performance and safety over equivalently sized hypergolic propellant systems in lunar vehicle ascent engine applications. LO2/LCH4 testing capability at altitude conditions did not previously exist at WSTF for this size engine, and modifications were made to the Auxiliary Propulsion Systems Test Bed (APSTB) article. Altitude simulation is achieved using the WSTF Large Altitude Simulation System, which provides altitude conditions equivalent to ~90,000 ft (~27 km). For specific impulse calculations, engine thrust and propellant mass flow rates are measured. Propellant flow rate is measured using a coriolis-style mass-flow meter, and accuracy is compared with a serial turbine-style flow meter. Thrust is measured using three load cells in parallel. Igniter system capability is being developed to demonstrate two methods, a gaseous oxygen/methane spark torch igniter and solid propellant pyrotechnic igniter. Design, procurement and assembly are complete for the test article and test readiness is expected for hot-fires to begin pending completion of manifold buildup and system checkout. Test objectives for the RS-18 project are 1) conduct a shakedown of the test stand for LO2/LCH4 lunar ascent engines, 2) obtain nozzle kinetics data to anchor twodimensional kinetics codes, and 3) obtain vacuum ignition data for the torch and pyrotechnic igniters.
The vicarious effects of hate: inter-ethnic hate crime in the neighborhood and its consequences for exclusion and anticipated rejection

ABSTRACT Hate crime victimization is harmful for victims and those who share the victim’s identity. It may also be harmful for the broader community. Yet, few studies focus on the ripple effects of hate. This paper examines how secondary exposure to hate crime in the neighborhood, through witnessing or hearing about hate crime, influences individual perceptions of ethnic minorities, which in turn can harm social relations. Findings reveal that those who witness hate crime express greater anger towards ethnic minorities. Those who rely on second-hand information about hate crime in the community are more likely to anticipate rejection on the basis of their ethnicity, hold negative attitudes towards ethnic migrants and intend to take actions to exclude new migrants from their communities when compared to those who do not have such information. These findings have implications for community cohesion in multi-ethnic neighborhoods.
State Reconstruction: Generating a Reference for Improved Diagnostics

Mechanical systems across most industries are mortal instruments, they will fail due to use or otherwise. Staying ahead of such catastrophes are crucial, especially in mission critical scenarios where loss of life is a very real danger. In such cases, corrective maintenance is too risky and scheduled maintenance is often costly; thus the collective shift towards predictive maintenance. Until recent advancements in artificial intelligence and sensor networks, such a strategy would not be so achievable. The ‘predictive’ aspect of thus type of maintenance implies that anomalies and failures are expected to be forecast ahead of occurrence - this can be accomplished with well placed sensors and sufficiently trained correlation methods. However, aspects such as shifting operating modes and varying sensor ranges make it difficult to make predictions solely using raw sensor data. This paper will outline methods and technologies to estimate healthy states of the monitored system to aid in the detection of failures before they affect function.

Conservation Policy, Type of Protected Area and Deforestation in Mainland Tanzania

Protected areas are an important means of controlling deforestation. However, the effectiveness of protected areas in controlling deforestation depends on type of protected area which determines conservation policy pursued and thus how the protected area is managed. This paper reports on analysis of the relationship between deforestation and type of protected area, namely forest reserve, game reserve and national park in mainland Tanzania. The analysis used maps covering the whole of mainland Tanzania for 1995 and 2010 and applied GIS analytical techniques. Both forest reserves and game reserves had lower deforestation than areas that were not protected whereas national parks had higher deforestation than areas that were not protected. However, forest reserves had higher rate of deforestation than game reserves. These results raise questions with regards to ecological processes and policy options relevant for the three types of protected areas and their effects on deforestation. First, are the differences in deforestation due to varying levels of effectiveness of measures used to control deforestation among the three types of protected areas? Second, what is the role of natural processes such as elephants that kill trees? Third, why should national parks be associated with the highest rate of deforestation? Are forests so bad for wild animals in national parks? These questions form the basis of the discussion of the results.
Understanding customers across national cultures: the influence of national cultural differences on designers’ empathic accuracy

For engineering design to be successful, it is essential to understand customer experience and identify customer needs. However, it is challenging to understand customers, especially those from different national cultures. The empathy literature suggests that having similar experiences to another person can help understand them better. This study adopts an empathy measure from psychology for use in a project where designers attempt to understand customers’ driving experiences in different countries and identify their needs for detecting road hazards. We quantify designers’ empathic accuracy and the correctness of their rating of customers’ emotional tone. The results show that national cultural differences significantly affect the accuracy of designers’ empathic understanding but do not impact their understanding of customers’ emotional tone.
Efforts to Improve English Speaking Ability of Five to Six-Years-Old Bilingual School Students Through Hand Puppet Media

This classroom action research was motivated by the five to six-year-old students’ low English speaking ability in bilingual schools, especially in pronouncing, adding vocabulary, and forming sentences. This research aims to improve the English language skills of five to six-year-old students using hand puppets. This research was conducted from April 9 to May 4, 2018, at the TK IT Al Ikhlas Islamic Bilingual School by employing Kemmis's and Mc Taggart’s model in two cycles with three meetings each. The subjects of this research consisted of twelve students (seven males and five females). Based on the research results, there was an increase in English language skills through hand puppet media. In conclusion, the factors affecting students’ English speaking skills are familiar vocabulary, clear and easy to imitate teacher's pronunciation, exciting and varied media, and opportunities for them to use hand puppets while imitating the teacher. The researchers concluded that the hand puppet media could improve the five to six-year-old students' language skills.
Novel Structure and Thermal Design and Analysis for CubeSats in Formation Flying

The CANYVAL-C (CubeSat Astronomy by NASA and Yonsei using a virtual telescope alignment for coronagraph) is a space science demonstration mission that involves taking several images of the solar corona with two CubeSats—1U CubeSat (Timon) and 2U CubeSat (Pumbaa)—in formation flying. In this study, we developed and evaluated structural and thermal designs of the CubeSats Timon and Pumbaa through finite element analyses, considering the nonlinearity effects of the nylon wire of the deployable solar panels installed in Pumbaa. On-orbit thermal analyses were performed with an accurate analytical model for a visible camera on Timon and a micro propulsion system on Pumbaa, which has a narrow operating temperature range. Finally, the analytical models were correlated for enhancing the reliability of the numerical analysis. The test results indicated that the CubeSats are structurally safe with respect to the launch environment and can activate each component under the space thermal environment. The natural frequency of the nylon wire for the deployable solar panels was found to increase significantly as the wire was tightened strongly. The conditions of the thermal vacuum and cycling testing were implemented in the thermal analytical model, which reduced the differences between the analysis and testing.
System modeling and characterization of enhanced valveless micropumps

Abstract This article provides a comprehensive analytical and numerical modeling procedure for characterizing the dynamics of flow fields in both the traditional circular and the new, efficiency- enhanced chambers of valveless micropump systems. The flow dynamics of the traditional circular valveless micropump system are analytically modeled and experimentally verified by comparing the results with data measured directly from a real-world system that has been discussed in the literature. The validated comprehensive modeling procedure is then extended to model the efficiency- enhanced micropump system in order to increase net flow rate and expanding the operational working range of the back pressure for possible micro devices aimed at applications for many high-performance industrial applications. A comparison of the associated system frequencies in both micropump systems shows, that the resonance frequency of the efficiency- enhanced micropump system is increased from 31 Hz to 38 Hz. The maximum net flow rate of the new system is also increased dramatically to a level of 1.74 ml/min, which is approximately 50% higher than that of the conventional setup. As long as the same input driving power is applied to both systems, the overall operating efficiency of the proposed micropump system is increased by approximately 58%. Meanwhile, the best- efficiency point (BEP) is stepped up from 0.56 ml/min to 1.1 ml/min. The enhancement of the BEP thus makes it possible for the back pressure to be operate more effectively in the range of 64 ∼ 100 Pa.
Optimizing landscape‐scale monitoring programmes to detect the effects of megafires

By virtue of their spatial extent, landscape‐scale monitoring programmes may be well‐suited to support before‐after/control‐impact (BACI) studies of major disturbances such as megafires, but they may only have a few affected sites, reducing statistical power. I tested whether a variety of hypothetical but logistically plausible survey designs could provide statistically powerful assessments of hypothetical but empirically based population responses to megafire.
Environmental shocks, civil conflict and aid effectiveness

Do natural disasters promote conflict or peace? A series of analyses of longitudinal data between 1971 and 2011 shows the modest but significant impact of natural disasters on the likelihood of conflict, conditional on the level of foreign aid in developing countries. This paper argues that frequent natural disasters, through the legitimacy effect and monitoring effect, allow foreign aid to be channeled to marginalized groups and used for its intended development purpose, eventually lowering the likelihood of conflict. This study is the first to incorporate an examination of foreign aid into an analysis of natural disasters and civil conflicts.
