26Al in cores of the Keyes chondrite

Cosmogenic 26Al was measured in six samples from two cores of the Keyes chondrite, previously analyzed for spallogenic 3He, 21Ne, and 38Ar. Specific activities varied from 68.9 ± 5.4 dpm/kg near the center (depth, ∼30 cm) to 50.9 ± 3.7 near the postatmospheric surface (depth, ∼3 cm). The data are consistent with an approximately linear decrease in 26Al activity with radial distance r from the center of Keyes: (26Al)obs/(26Al)calc = 1.04 (±0.05) − 0.0104 (±0.0032)(r). The measured 26Al (dpm/kg)/21Ne(10−8 cm3/g) ratio is constant at 6.13 ± 0.18 for the six samples, corresponding to an average atomic production ratio of 0.222 for the meteorite.
Insights on Investment Psychology of Individual Investors at Dhaka Stock Exchange (DSE) During The Covid-19 Pandemic

Almost all calamities make a footmark on the financial sector, and COVID-19 is no different. On this ground, stock market investors' attitudes, thinking, and everything receives severe attention as investors' psychology is a common determinant of the trading activity and investment decisions which ultimately drive the market. Investors in developing countries like Bangladesh need a more rigorous analysis of their behavior as they are now more concerned and worried about their investments than before. They must be more vigilant in terms of preparation to eliminate the impacts of COVID-19. This paper aims at focusing on understanding how the spread of the pandemic is reshaping the psychological aspect of investors with a focus on four selected factors, risk perception, market psychology, media effect, and loss aversion. Three hundred eighty-five responses were collected through a questionnaire during the COVID-19 pandemic, where data was tested using Smart PLS 3.0 in conjunction with IBM SPSS 25. With the help of the measurement model and structural model of partial least square, the suggested framework in this paper has been studied to identify some aspects of investors' psychology that could potentially have insights and information on how countries should place themselves to respond to future epidemics. The effect size and individual t-test of the factors explain the affected state of thinking of retail investors, where loss aversion and risk perception affect investors the most. In contrast, media effects have a moderate influence, and market psychology has the least. The findings are expected to help investors and policymakers understand the behavior of the market and prepare accordingly for challenging the upcoming economic crisis in the corona war.
A case for film as an andragogical tool for business schools in Africa: Trends, challenges and prospects

ABSTRACT This article extends the work of existing studies on the development of learners to be ethical leaders in Africa. It makes a case for the use of film as an andragogical tool in the education of adult learners in Africa. Premised on social learning theory, the paper proposes that film, as an audio-visual case study that offers a cinematic experience, accommodates students’ varying learning styles. It is found to be resourceful in the dissemination of ideas or knowledge of particularly recommended subjects such as leadership and ethics. Purely based on secondary data, key themes uncovering the challenges and prospects of using film, especially in Nigeria are discussed. In addition to the systematic literature review results showing a poor trend of film usage in Africa higher education settings, a strong case was made for the use of film analysis given its practical relevance, components, and benefits. Beyond achieving the set objectives, a key contribution is the proposition for an enhanced reflective practice to accentuate the third phase of social learning theory and promote experiential learning which is more engaging for students. Future studies can gather primary data to explore how film is used in African business schools and evaluate its impact on adult learners.
Incidence and severity of pulmonary embolism in COVID-19 infection: Ancestral, Alpha, Delta, and Omicron variants

Little information is available regarding incidence and severity of pulmonary embolism (PE) across the periods of ancestral strain, Alpha, Delta, and Omicron variants. The aim of this study is to investigate the incidence and severity of PE over the dominant periods of ancestral strain and Alpha, Delta, and Omicron variants. We hypothesized that the incidence and the severity by proximity of PE in patients with the newer variants and vaccination would be decreased compared with those in ancestral and earlier variants. Patients with COVID-19 diagnosis between March 2020 and February 2022 and computed tomography pulmonary angiogram performed within a 6-week window around the diagnosis (−2 to +4 weeks) were studied retrospectively. The primary endpoints were the associations of the incidence and location of PE with the ancestral strain and each variant. Of the 720 coronavirus disease 2019 patients with computed tomography pulmonary angiogram (58.6 ± 17.2 years; 374 females), PE was diagnosed among 42/358 (12%) during the ancestral strain period, 5/60 (8%) during the Alpha variant period, 16/152 (11%) during the Delta variant period, and 13/150 (9%) during the Omicron variant period. The most proximal PE (ancestral strain vs variants) was located in the main/lobar arteries (31% vs 6%–40%), in the segmental arteries (52% vs 60%–75%), and in the subsegmental arteries (17% vs 0%–19%). There was no significant difference in both the incidence and location of PE across the periods, confirmed by multivariable logistic regression models. In summary, the incidence and severity of PE did not significantly differ across the periods of ancestral strain and Alpha, Delta, and Omicron variants.
The 2011 Mw 9.0 Tohoku Earthquake: Comparison of GPS and Strong‐Motion Data

Near‐field ground‐motion data are available in semi‐real time either from modern strong‐motion or continuous Global Positioning System (GPS) networks, allowing robust solutions for earthquake source parameters, which are useful for rapid disaster assessment and early warning. These wide applications require the ground‐motion data to cover a very broad frequency band that, however, is usually not available. This paper presents a case study on the 2011 M w 9.0 Tohoku earthquake, showing how the ground‐motion information from geodetic and seismic instrumentations is complementary, and suggesting the joint use of both types of data, particularly when the network coverage is sparse. First the strong‐motion records from the two Japanese networks, K‐NET and KiK‐Net, are analyzed using an automatic empirical baseline correction tool. The static coseismic displacement data are obtained by double integration and then used to derive the permanent slip distribution on the earthquake fault. Comparisons with the corresponding GPS‐based solutions yield a quantitative estimation of uncertainties of the empirical baseline correction. Furthermore, a dozen nearby GPS and strong‐motion station pairs are selected to demonstrate that the information in their time series agrees with each other. Finally, methods for combining both types of ground‐motion observation systems are discussed, and the wide applicability of this approach is highlighted.
Water quality characteristics of road runoff from urban area of Guangzhou

Many kinds of pollutants such as suspended solid, oil and grease and heavy metals derived from traffic activities were enriched in urban road runoff, and they could significantly degrade the quality of the receiving waters and affect hydro-ecosystem. Water quality of the road runoff from Guangzhou urban area was analyzed with synchronous measurement of the rainfall and runoff volume. The results indicated that the contents of nutritive salts were low, but COD as well as oil and grease and heavy metals were high in the runoff, and the low ratio of BOD to COD suggested low bio-degradability of the road runoff water. Although the mean concentrations of oil and grease, suspended solid and Pb generally fell within the same range of the level from other cities in China, they were considerably higher than the developed countries’ level, reflecting the gap on environment maintenance and management of the roads between China and developed countries. Comparing with Chinese surface water quality criteria type III, the levels of oil grease, COD, suspended solids and Pb in road runoff substantially exceeded the limited concentrations, indicating that untreated discharge of road runoff from Guangzhou urban area could seriously deteriorate the water quality of receiving waters such as Pearl River.
Lenalidomide use in multiple myeloma (Review)

Lenalidomide is a second-generation new immunomodulatory medication used to treat multiple myeloma (MM). Its mechanism of action involves affecting the expression of vascular endothelial growth factor, interleukin-6, cytochrome c, caspase-8, as well as other factors including immunological modulation and the direct killing of cells, among others, rendering it a fundamental medication, useful for the treatment of MM. Combining lenalidomide with other medications such dexamethasone, bortezomib, ixazomib, carfilzomib and daratumumab can markedly alleviate MM. When autologous-hematopoietic stem cell transplantation (ASCT) cannot be utilized to treat newly diagnosed individuals with MM (NDMM), monotherapy maintenance following lenalidomide and dexamethasone may be employed. Following ASCT, single-agent maintenance with lenalidomide can be performed as an additional treatment. The combination of bortezomib and lenalidomide has been demonstrated to be associated with favorable response rates, tolerable toxicity, and therapeutic benefits although caution is warranted to prevent the onset of peripheral neuropathy with its use. A new-generation oral drug with an excellent safety profile, ixazomib, is more practical and therapeutically applicable in relapsed refractory MM. However, the frequent occurrence of cardiovascular events, hematocrit, and infections with it require flexible adjustment in its clinical application. Carfilzomib produces a rapid and profound response in patients with NDMM eligible for transplantation, but its cardiovascular side effects need to be closely monitored. The primary aim of the present review was to examine the pharmacological properties and pharmacokinetics of lenalidomide, as well as the efficacy and safety of lenalidomide-based treatments with reference to data from clinical trials and real-world studies.
IIM: an information interaction mechanism for aspect-based sentiment analysis

ABSTRACT Term polarity co-extraction is an aspect-based sentiment analysis task, which has been widely used in the fields of user opinions extraction. It consists of two subtasks: aspect term extraction and aspect sentiment classification. Most existing studies solve aforesaid subtasks as independent tasks or simply unify the two subtasks without making full use of the relationship between tasks to mine the interaction of text information, which leads to low performance for practical applications. Meanwhile, the learning framework for these studies has a label drift phenomenon (LDP) in the process of predictive learning, increasing the learning error rate. To address the above problems, this study unifies subtasks and proposes a Unified framework based on the information interaction mechanism framework, called IIM. Specifically, we design an Information Interaction Channel (IIC) to construct closer semantic features to extract preliminary term-polarity unified labels from the perspective of basic semantics. For label inconsistency between aspect terms, a Position-aware Module (SAM) is proposed to alleviate the Label Drift Phenomenon (LDP). Moreover, we introduce a syntax-attention graph neural network (Syn-AttGCN) to model the syntactic structure of text and strengthen the emotional connection between aspect terms. The experimental results show that IIM outperforms most baselines. Meanwhile, the SAM module has a certain slowing effect on LDP.
Distribution, Abundance and Diversity of Benthic Macroinvertebrates on the Canadian Continental Shelf and Slope of Southern Davis Strait and Ungava Bay

Stations in a survey of benthic invertebrates on the Canadian continental shelf and slope of southeastern Baffin Island, in Ungava Bay, and on the northern Labrador Shelf, fell into definite groups as a result of an objective analysis of similarity in species composition. The groupings were shown to correspond to major water masses in the area. Groups corresponding to cold surface water masses, to the deep Irminger Atlantic water mass, and to mixtures of these with adjacent water masses were observed. The Irminger Atlantic group dominated on the Baffin Island continental shelf. Species diversity, also measured in the study, was high, with large numbers of species present in low abundance. Key words: marine, benthos, invertebrates, distribution, shelf, slope, Davis Strait, Ungava Bay, subartic

Ship Wave-Induced Sedimentation of a Tidal Creek in Galveston Bay

During the summer of 2005, a tidal creek (“Pine Gully”) within a few kilometers of the Houston Ship Channel was completely blocked by a 200 m long and 1.5 m deep plug of silt and fine sand. This paper documents and explains this unusual sedimentation event. It then presents a new method for calculating ship wave-induced sediment transport into tidal creeks. Between November 2005 and January 2006, measurements of velocity, pressure, and suspended sediment concentration were taken in the creek approximately 150 m seaward of the plug. The data indicated ship wave-induced bores (one per ship). Each bore caused a net sediment transport of approximately 0.4 m3 toward the plug, enough to explain the observed rate of sediment accumulation. Cores of the plug showed that the plug material was consistent throughout, suggesting a single pathway (from the bay). During the period of plug formation, rainfall and creek discharge were relatively low indicating a likely factor for the plugging. Model calculations showed th.
Age of the Lava Creek supereruption and magma chamber assembly at Yellowstone based on 40Ar/39Ar and U‐Pb dating of sanidine and zircon crystals

The last supereruption from the Yellowstone Plateau formed Yellowstone caldera and ejected the >1000 km3 of rhyolite that composes the Lava Creek Tuff. Tephra from the Lava Creek eruption is a key Quaternary chronostratigraphic marker, in particular for dating the deposition of mid Pleistocene glacial and pluvial deposits in western North America. To resolve the timing of eruption and crystallization history for the Lava Creek magma, we performed (1) 40Ar/39Ar dating of single sanidine crystals to delimit eruption age and (2) ion microprobe U‐Pb and trace‐element analyses of the crystal faces and interiors of single zircons to date the interval of zircon crystallization and characterize magmatic evolution. Sanidines from the two informal members composing Lava Creek Tuff yield a preferred 40Ar/39Ar isochron date of 631.3 ± 4.3 ka. Crystal faces on zircons from both members yield a weighted mean 206Pb/238U date of 626.5 ± 5.8 ka, and have trace element concentrations that vary with the eruptive stratigraphy. Zircon interiors yield a mean 206Pb/238U date of 659.8 ± 5.5 ka, and reveal reverse and/or oscillatory zoning of trace element concentrations, with many crystals containing high U concentration cores that likely grew from highly evolved melt. The occurrence of distal Lava Creek tephra in stratigraphic sequences marking the Marine Isotope Stage 16–15 transition supports the apparent eruption age of ∼631 ka. The combined results reveal that Lava Creek zircons record episodic heating, renewed crystallization, and an overall up‐temperature evolution for Yellowstone's subvolcanic reservoir in the 103−104 year interval before eruption.
Quantitative palaeoclimate GCM validation: Late Jurassic and mid-Cretaceous case studies

Using quantitative proxy models of peat and bauxite formation, based upon modern analogues, predictions of the distribution of peats (coals) and bauxites for both the Late Jurassic (Kimmeridgian) and mid-Cretaceous (Cenomanian) have been made using a General Circulation Model (GCM). The predictions have been compared with the known distribution of these deposits. Such an approach provides a means of identifying and isolating which components of the GCM accurately reflect palaeoclimate. The prediction of peats and bauxites for the Jurassic and Cretaceous show good correspondence with known coals and bauxites and provides otherwise elusive quantitative estimates of high latitude climate. The GCM is thus successfully replicating precipitation and mean annual temperatures for both the Kimmeridgian and Cenomanian. Investigations of Mesozoic palaeoclimate using General Circulation Models (GCMs) have often focused on qualitative evaluation of results (e.g. Barron & Washington 1982; Valdes et al. 1995; Chandler et al. 1992). A number of recent studies have, however, highlighted the need for GCM predictions to be quantitatively validated against the sedimentological and palaeobiological record (e.g. Poore & Chandler 1994; Pollard & Schulz 1994; Price et al. 1995). Quantitative estimates of terrestrial climate have been produced by physiognomic analysis of floras (e.g. Herman & Spicer 1996; Wolfe & Upchurch 1987), and have also been derived from organisms such as crocodiles (e.g. Markwick 1994). Comparable results have been used effectively for validating GCM predictions (e.g. Sloan & Barron 1992), but data tend to be restricted to North America and are often Latest Cretaceous, or younger, in age.
A Novel Therapy for Cisplatin-Induced Allodynia and Dysfunctional and Emotional Impairments in Male and Female Mice

Patients undergoing chemotherapy with cisplatin (CIS) develop neuropathy in addition to other symptoms such as, anxiety, depression, muscle wasting and body weight loss. This symptomatology greatly weakens patients and may even lead to adjournment of chemotherapy. The protecting actions of molecular hydrogen in many neurological illnesses have been described, but its effect on the functional and emotional deficiencies caused by CIS has not been assessed. In C57BL/6J male and female mice injected with CIS, we examined the impact of the prophylactic treatment with hydrogen-rich water (HRW) on: (i) the tactile and cold allodynia, (ii) the deficits of grip strength and weight loss, (iii) the anxiodepressive-like behaviors and (iv) the inflammatory and oxidative reactions incited by CIS in the dorsal root ganglia (DRG) and prefrontal cortex (PFC). The results demonstrate that the mechanical allodynia and the anxiodepressive-like comportment provoked by CIS were similarly manifested in both sexes, whereas the cold allodynia, grip strength deficits and body weight loss produced by this chemotherapeutic agent were greater in female mice. Nonetheless, the prophylactic treatment with HRW prevented the allodynia and the functional and emotional impairments resulting from CIS in both sexes. This treatment also inhibited the inflammatory and oxidative responses activated by CIS in the DRG and PFC in both sexes, which might explain the therapeutic actions of HRW in male and female mice. In conclusion, this study revealed the plausible use of HRW as a new therapy for the allodynia and physical and mental impairments linked with CIS and its possible mechanism of action.
The mediation role of safety training between risk perception and safety behaviors among non-medical hospital staff

The relationship between risk perception and safety outcomes has been extensively studied in the past, but there is scarce research on the mediating effect of safety training on risk perception and both safety dimensions of safety behaviors in hospital settings. This study investigates the role of safety training as a mediator in the relationship between risk perception and safety behavior, as measured by compliance and participation in safety measures. The cross-sectional data from one big private hospital in Saudi Arabia was examined using the most recent iteration of Smart Partial Least Squares (PLS4). A 71% response rate was achieved on surveys that were personally handed out to 155 non-medical staff in hospitals. In this study, the significance level for Percentile Bootstrapping with a 95% confidence interval and p ≤ 0.05 was utilized to analyze mediation. Safety training served as a full mediating variable in the link between risk perception and safety compliance. Surprisingly, safety training did not act as a mediator in the relationship between risk perception and safety participation. This study fills a gap in the body of knowledge about non-medical staff's attitudes toward risk, safety training, and safety behaviors. Additionally, it helps us comprehend how safety training can help people perceive risks and behave safely. Considering that hospital management and safety officials receive high-quality training on safety concerns, more workers follow safety precautions, and the number of workplace accidents is reduced. The results of this study can be used as a foundation for future studies to enhance occupational safety practices.
