An Implantable Magneto-Responsive Poly(aspartamide) Based Electrospun Scaffold for Hyperthermia Treatment

When exposed to an alternating magnetic field, superparamagnetic nanoparticles can elicit the required hyperthermic effect while also being excellent magnetic resonance imaging (MRI) contrast agents. Their main drawback is that they diffuse out of the area of interest in one or two days, thus preventing a continuous application during the typical several-cycle multi-week treatment. To solve this issue, our aim was to synthesise an implantable, biodegradable membrane infused with magnetite that enabled long-term treatment while having adequate MRI contrast and hyperthermic capabilities. To immobilise the nanoparticles inside the scaffold, they were synthesised inside hydrogel fibres. First, polysuccinimide (PSI) fibres were produced by electrospinning and crosslinked, and then, magnetitc iron oxide nanoparticles (MIONs) were synthesised inside and in-between the fibres of the hydrogel membranes with the well-known co-precipitation method. The attenuated total reflectance Fourier-transform infrared spectroscopy (ATR-FTIR) investigation proved the success of the chemical synthesis and the presence of iron oxide, and the superconducting quantum interference device (SQUID) study revealed their superparamagnetic property. The magnetic hyperthermia efficiency of the samples was significant. The given alternating current (AC) magnetic field could induce a temperature rise of 5 °C (from 37 °C to 42 °C) in less than 2 min even for five quick heat-cool cycles or for five consecutive days without considerable heat generation loss in the samples. Short-term (1 day and 7 day) biocompatibility, biodegradability and MRI contrast capability were investigated in vivo on Wistar rats. The results showed excellent MRI contrast and minimal acute inflammation.
STUDY OF FACTORS AFFECTING THE LIQUIDITY OF FUTURES CONTRACTS, REGARDING ORDER-BASED CRITERIA

In a liquid market, trades could take place quickly and at a fair price. Considering the importance of liquidity as one of the main indexes of financial markets efficiency, recognizing the factors affecting this phenomenon is a great matter of importance.In this regard, the present study aimed to examine factors affecting the liquidity in Iran’s gold futures market using the data of gold coin future contracts from 2017 to 2018. Being more precise in liquidity measurement due to the concentration on the current market situation, as well as, having a better performance than trading-based criteria in such applications, two order-based criteria of “bid and ask spread” and “the depth of market” were taken into account.Considering the related literature, the most important factors on liquidity such as trade volume, volatility, and price level were identified to investigate their impacts on the liquidity criteria. Subsequently, employing the multivariate linear regression led to the conclusion thatthere is a significant and direct relationship between the volatility of futures contract prices and the depth of market in future contracts on gold coin in Iran Mercantile Exchange (IME) while, the relation between the other factors with the aforementioned criteria are negligible.

Perceived Employability and Task Performance: Examining the Impact of Occupational Self Efficacy and Turnover Intention

The aim of the study was to uncover the impact of occupational self-efficacy and employee’s turnover intention on perceived employability and task performance relationship. A sample of 80 project managers, 130 team leaders and 190 software developers working in the information technology sector were selected from Islamabad, Rawalpindi, Lahore and Karachi. The data collection was conducted through self-administered questionnaires and online survey. The results show that occupational self-efficacy has a positive influence on perceived employability and task performance relationship. It also reveals that occupational self-efficacy has a strong influence on perceived employability and turnover intention and turnover intention to task performance relationships. This research also indicates a stronger direct influence of occupational self-efficacy on perceived employability and task performance relationship as compared to the indirect influence of occupational self-efficacy on perceived employability to task performance via turnover intention relationship. The study suggests the importance of employee’s perceived employability to emphasize their intention to stay with the organization but it is often based on the perceive career guarantees from the organizations instead of their affection with the organization.
Which Factors Influence the Regional Difference of Urban–Rural Residential CO2 Emissions? A Case Study by Cross-Regional Panel Analysis in China

Residential CO2 emissions (RCE) are an important component of anthropogenic CO2 emissions. In order to formulate reasonable reduction policies and measures, it is necessary to understand the dynamics of RCE production and the factors that influence it. This paper explores the spatiotemporal evolution characteristics of RCE from the perspectives of eastern, central, and western China, as well as urban–rural areas, and analyzes the factors driving RCE based on the STIRPAT model. The results indicated that between 2010 and 2019 the eastern region contributed the greatest proportion of overall RCE and the central region saw the largest increase. Per capita RCE in urban areas was greater than in rural areas, except in eastern China. The factors affecting RCE showed regional and urban–rural differences. Population size and income per capita were two dominant factors affecting RCE for all regions. The per capita income plays a more important role in developed regions such as eastern regions and eastern urban areas. Urbanization contributed to RCE reduction in the eastern region but promoted RCE in the central and western regions. Energy structure shows a negative effect on RCE, particularly in central urban and western rural areas. Appropriate policies and measures need to be put forward to local conditions. Reduction policies and measures of each region and urban–rural area need to be based on the dominant factors driving CO2 emissions.
New Methodology for Design and Construction of Concrete Members with Complex Stress Fields Using Steel Fiber–Reinforced Concrete

AbstractReinforced concrete members with significant geometric discontinuities or D-regions experience complex stress fields under loading, which require considerable analytical effort and usually complicated reinforcement detailing. Large openings in RC members can interrupt the direct load transfer provided by concrete struts, thereby leading to overstressed localized regions and unexpected failure modes. Empirically based strut-and-tie models (STMs) are generally used to design the reinforcement detailing of these RC members. However, many prior studies indicate that the resulting details can be very complicated while the actual stress fields deviate significantly from that assumed by STMs, thereby leading to unpredictable failure modes. This study investigates the feasibility of using steel fibers to replace the majority of conventional reinforcing bars in RC deep beams with significant D-regions. The test beams have two large openings, which are located between the loading point and the supports, thu.

Estimating freeway travel time and its reliability using radar sensor data

ABSTRACT Travel time and its reliability are intuitive system performance measures for freeway traffic operations. This paper proposes a method to estimate travel times based on data collected from roadside radar sensors, considering spatially correlated traffic conditions. Link-level and corridor-level travel time distributions are estimated using these travel time estimates and compared with the ones estimated based on probe vehicle data. The maximum likelihood estimation is used to estimate the parameters of Weibull, gamma, normal, and lognormal distributions. According to the log-likelihood values, lognormal distribution is the best fit among all the tested distributions. Corridor-level travel time reliability measures are extracted from the travel time distributions. The proposed travel time estimation model can well capture the temporal pattern of travel time and its distribution.
Do Smartphone Applications Aid in Weight Loss? A Study on the Efficacy of Apps as a Supplemental Weight-Loss Aid

Over the past decade, mobile technology has been developed in the hopes of improving health outcomes, especially related to weight loss. The purpose of this study was to evaluate the effectiveness of a smartphone application as a supplementary weight loss tool among highly motivated individuals . Twenty-five individuals over the age of 1 8 were included in the study based on BMI and participation in a Midwest weight-loss clinic . Intervention group participants (n = 1 3 ) were instructed to use the MyFitnessPal app to monitor food intake and receive SMS-style nutritional messages. The control group (n = 1 2) received no mobile-based intervention, but was not limited on their own use of the technology. All participants attended weekly nutrition counseling sessions at the clinic . Qualitative and quantitative measures were used to evaluate the effectiveness of the intervention. At the end of the four-week study, the amount of weight lost compared between groups was minimal . App use decreased among intervention group participants ; however, more than half of the control group (n = 7) reported app use throughout the study. The nutritional messages were well-received by the intervention group and a positive correlation was found between message use and weight loss. Although varied outcomes were determined, mobile technology should not be disregarded as an effective weight loss tool . Many participants reported positive feedback in regards to the app and more notably the nutritional messages, suggesting that mobile­ based weight-loss interventions should consider the motivation levels and preferences of the individuals who are using them.
Interplay between Young Stars and Molecular Clouds in the Ophiuchus Star-forming Complex

We present spatial and kinematic correlation between the young stellar population and the cloud clumps in the Ophiuchus star-forming region. The stellar sample consists of known young objects at various evolutionary stages, taken from the literature, some of which are diagnosed with Gaia EDR3 parallax and proper-motion measurements. The molecular gas is traced by the 850 μm Submillimetre Common-User Bolometer Array-2 image, reaching ∼2.3 mJy beam−1, the deepest so far for the region, stacked from the James Clerk Maxwell Telescope/Transient program aiming to detect submillimeter outburst events. Our analysis indicates that the more evolved sources, namely the class II and III young stars, are located further away from clouds than class I and flat-spectrum sources that have ample circumstellar matter and are closely associated with natal clouds. Particularly the class II and III population is found to exhibit a structured spatial distribution indicative of passage of shock fronts from the nearby Sco–Cen OB association thereby compressing clouds to trigger star formation, with the latest starbirth episode occurring now in the densest cloud filaments. The young stars at all evolutionary stages share similar kinematics. This suggests that the stellar patterns trace the relics of parental cloud filaments that now have been dispersed.
Doing More With Less: Teacher Professional Learning Doing More With Less: Teacher Professional Learning Communities in Resource-Constrained Primary Schools in Rural Communities in Resource-Constrained Primary Schools in Rural China China

Abstract Teacher professional learning communities provide environments in which teachers engage in regular research and collaboration. They have been found effective as a means for connecting professional learning to the day-to-day realities faced by teachers in the classroom. In this article, the authors draw on survey data collected in primary schools serving 71 villages in rural Gansu Province as well as transcripts from in-depth interviews with 30 teachers. Findings indicate that professional learning communities penetrate to some of China’s most resource-constrained schools but that their nature and development are shaped by institutional supports, principal leadership, and teachers’ own initiative.

Integrated demand-responsive scheduling of maintenance and transportation operations in military supply chains

The management of a military supply chain (SC) involves the integration of production, packaging, warehousing, repair, maintenance and transportation of army supplies. In this paper, we focus on the integrated demand-responsive scheduling of maintenance and transportation operations within the SC. We consider a modular representation of a SC, in which the maintenance and transportation operations constitute the corresponding modules. An efficient integration of these operations is carried out by an additional controlling (commanding) module. We describe and analyse the optimisation problems arising in each module. The main contribution of the paper is that the analysis and optimisation of the controlling module permit to enhance the performance of the entire SC. Computational experiments prove the validity and effectiveness of the suggested models.
Characterization of autonomic symptom burden in long COVID: A global survey of 2,314 adults

Background Autonomic dysfunction is a known complication of post-acute sequelae of SARS-CoV-2 (PASC)/long COVID, however prevalence and severity are unknown. Objective To assess the frequency, severity, and risk factors of autonomic dysfunction in PASC, and to determine whether severity of acute SARS-CoV-2 infection is associated with severity of autonomic dysfunction. Design Cross-sectional online survey of adults with PASC recruited through long COVID support groups between October 2020 and August 2021. Participants 2,413 adults ages 18–64 years with PASC including patients who had a confirmed positive test for COVID-19 (test-confirmed) and participants who were diagnosed with COVID-19 based on clinical symptoms alone. Main measures The main outcome measure was the Composite Autonomic Symptom 31 (COMPASS-31) total score, used to assess global autonomic dysfunction. Test-confirmed hospitalized vs. test-confirmed non-hospitalized participants were compared to determine if the severity of acute SARS-CoV-2 infection was associated with the severity autonomic dysfunction. Key results Sixty-six percent of PASC patients had a COMPASS-31 score >20, suggestive of moderate to severe autonomic dysfunction. COMPASS-31 scores did not differ between test-confirmed hospitalized and test-confirmed non-hospitalized participants [28.95 (15.62, 46.60) vs. 26.4 (13.75, 42.10); p = 0.06]. Conclusions Evidence of moderate to severe autonomic dysfunction was seen in 66% of PASC patients in our study, independent of hospitalization status, suggesting that autonomic dysfunction is highly prevalent in the PASC population and independent of the severity of acute COVID-19 illness.
Effects of boosted mRNA and adenoviral‐vectored vaccines on immune responses to omicron BA.1 and BA.2 following the heterologous CoronaVac/AZD1222 vaccination

The coronavirus 2019 omicron variant has surged rapidly and raises concerns about immune evasion even in individuals with complete vaccination, because it harbors mutations. Here we examine the capability of booster vaccination following CoronaVac/AZD1222 prime to induce neutralizing antibodies (NAbs) against omicron (BA.1 and BA.2) and T‐cell responses. A total of 167 participants primed with heterologous CoronaVac/AZD1222 for 4–5 months were enrolled, to receive AZD1222, BNT162b2, or mRNA‐1273 as a third dose. Reactogenicity was recorded. Immunogenicity analyses of severe acute respiratory syndrome coronavirus 2‐binding antibodies were measured using enzyme‐linked immunosorbent assay. The NAb titers against omicron BA.1 and BA.2 were determined using the focus reduction neutralization test (FRNT50) and total interferon‐γ responses were measured to observe the T‐cell activation. A substantial loss in neutralizing potency to omicron variant was found at 4–5 months after receiving the heterologous CoronaVac/AZD1222. Following booster vaccination, a significant increase in binding antibodies and neutralizing activities toward delta and omicron variants was observed. Neutralization to omicron BA.1 and BA.2 were comparable, showing the highest titers after boosted mRNA‐1273 followed by BNT162b2 and AZD1222. In addition, individuals boosted with messenger RNA (mRNA) vaccines develop a T‐cell response to spike protein, whereas those boosted with AZD1222 did not. Reactogenicity was mild to moderate without serious adverse events. Our findings demonstrated that mRNA booster vaccination is able to overcome waning immunity to provide antibodies that neutralize omicron BA.1 and BA.2, as well as a T‐cell response.
