Factors for Successful Science Learning in a Flexible Mode amid Covid-19 Educational Disruption: Students’ Assessment

Due to the educational disruption caused by the COVID-19 pandemic, educational institutions resorted to flexible learning modalities to continue the education of students and avoid learning losses. This descriptive online survey assessed different factors for successful science learning in a flexible mode utilized during the current learning setup. A total of 50 teacher education students specializing in science from the two campuses of a state university in Zambales, Philippines, responded to the researcher-crafted survey questionnaire (a=0.971). Results of the study showed that most of the respondents are using the online asynchronous learning modality. Almost all of them are using smartphones for their flexible learning. The college students strongly agree that instructor characteristics is a primary factor for successful science learning in a flexible mode, followed by internet accessibility, administrative support, course content and design, technical support, learner characteristics, and social support. Significant differences were noted in the factors for successful science learning in a flexible mode when grouped according to the learning modality used. Furthermore, positive significant moderate to high correlations were observed among factors for successful science learning in a flexible mode. The study suggests that schools may provide instructors with training and seminars about flexible education to further enhance their content knowledge and pedagogy in science, specifically in this educational disruption. Additionally, the university may craft programs and policies that address students' concerns in the current learning setup to avoid learning losses. These programs and policies could make the current learning modality more effective, efficient, and responsive to the students' needs, and more conducive for both faculty and students. Future researchers could conduct a further study to evaluate college students' experiences in flexible learning modalities in university for the past semesters.
Exposure to World Trade Center Dust Exacerbates Cognitive Impairment and Evokes a Central and Peripheral Pro-Inflammatory Transcriptional Profile in an Animal Model of Alzheimer’s Disease

Background: The terrorist attacks on September 11, 2001, on the World Trade Center (WTC) led to intense fires and a massive dense cloud of toxic gases and suspended pulverized debris. In the subsequent years, following the attack and cleanup efforts, a cluster of chronic health conditions emerged among First Responders (FR) who were at Ground Zero for prolonged periods and were repeatedly exposed to high levels of WTC particulate matter (WTCPM). Among those are neurological complications which may increase the risk for the development of Alzheimer’s disease (AD) later in life. Objective: We hypothesize that WTCPM dust exposure affects the immune cross-talking between the periphery and central nervous systems that may induce brain permeability ultimately promoting AD-type phenotype. Methods: 5XFAD and wild-type mice were intranasally administered with WTCPM dust collected at Ground Zero within 72 h after the attacks. Y-maze assay and novel object recognition behavioral tests were performed for working memory deficits and learning and recognition memory, respectively. Transcriptomic analysis in the blood and hippocampus was performed and confirmed by RT qPCR. Results: Mice exposed to WTCPM dust exhibited a significant impairment in spatial and recognition short and long-term memory. Furthermore, the transcriptomic analysis in the hippocampal formation and blood revealed significant changes in genes related to immune-inflammatory responses, and blood-brain barrier disruption. Conclusion: These studies suggest a putative peripheral-brain immune inflammatory cross-talking that may potentiate cognitive decline, identifying for the first time key steps which may be therapeutically targetable in future studies in WTC FR.
Relation Learning Using Temporal Episodes for Motor Imagery Brain-Computer Interfaces

For practical motor imagery (MI) brain-computer interface (BCI) applications, generating a reliable model for a target subject with few MI trials is important since the data collection process is labour-intensive and expensive. In this paper, we address this issue by proposing a few-shot learning method called temporal episode relation learning (TERL). TERL models MI with only limited trials from the target subject by the ability to compare MI trials through episode-based training. It can be directly applied to a new user without being re-trained, which is vital to improve user experience and realize real-world MIBCI applications. We develop a new and effective approach where, unlike the original episode learning, the temporal pattern between trials in each episode is encoded during the learning to boost the classification performance. We also perform an online evaluation simulation, in addition to the offline analysis that the previous studies only conduct, to better understand the performance of different approaches in real-world scenario. Extensive experiments are completed on four publicly available MIBCI datasets to evaluate the proposed TERL. Results show that TERL outperforms baseline and recent state-of-the-art methods, demonstrating competitive performance for subject-specific MIBCI where few trials are available from a target subject and a considerable number of trials from other source subjects.
Water waves, nonlinear Schrödinger equations and their solutions

Abstract Equations governing modulations of weakly nonlinear water waves are described. The modulations are coupled with wave-induced mean flows except in the case of water deeper than the modulation length scale. Equations suitable for water depths of the order the modulation length scale are deduced from those derived by Davey and Stewartson [5] and Dysthe [6]. A number of ases in which these equations reduce to a one dimensional nonlinear Schrödinger (NLS) equation are enumerated. Several analytical solutions of NLS equations are presented, with discussion of some of their implications for describing the propagation of water waves. Some of the solutions have not been presented in detail, or in convenient form before. One is new, a “rational” solution describing an “amplitude peak” which is isolated in space-time. Ma's [13] soli ton is particularly relevant to the recurrence of uniform wave trains in the experiment of Lake et al.[10]. In further discussion it is pointed out that although water waves are unstable to three-dimensional disturbances, an effective description of weakly nonlinear two-dimensional waves would be a useful step towards describing ocean wave propagation.
Developing Context-Based Teaching Competencies of Chemistry Teachers: Designing and Implementing Context-Based Activities

Context-based teaching is the use of contexts as a starting point for the development of scientific ideas in learning environments. Teachers can use this teaching approach to increase students' motivation and willingness to learn science. The focus of this research was to develop context-based teaching competencies of teachers. With this in mind, this research aimed to determine the effects of feedback on the development of teachers' context-based teaching competency and the factors affecting the teaching process. In the study, collective case study design was employed. The study was carried out with two chemistry teachers who participated in the In-Service Training Course on Context-Based Chemistry Teaching conducted by the researcher. The data of the research were collected through field notes, semi-structured interview, follow up interviews and video recordings. As a result of the research, it was determined that the feedback had a positive effect on the development of chemistry teachers' context-based teaching competency. It was revealed that teacher anxiety, professional knowledge, difficulty in designing materials and lack of interest of students affected the teaching process.

Moringa oleifera and Propolis in Cattle Nutrition: Characterization of Metabolic Activities in the Rumen In Vitro

Moringa oleifera by-products such as seed cake and leaves are protein-rich ingredients, while raw propolis has the potential to influence ruminal protein metabolism. These substances are also known to be sources of functional compounds. With these properties, they could modulate ruminal fermentation activities. Using the rumen simulation technique, we investigated ruminal fermentation and the antioxidant properties of four dietary treatments. These included a control diet (CON) without supplementation; the CON diet top-dressed on a dry matter (DM) basis, either with moringa seed cake (MSC, containing 49% crude protein (CP)), moringa leaf powder (ML, containing 28% CP), or raw propolis (PRO, 3% CP). MSC, ML, and PRO accounted for 3.8, 7.4, and 0.1% of the total diet DM, respectively. Both ML and MSC resulted in 14 and 27% more ammonia concentration, respectively than CON and PRO (p < 0.05). MSC increased the propionate percentage at the expense of acetate (p < 0.05). Both ML and MSC decreased methane percentages by 7 and 10%, respectively, compared to CON (p < 0.05). The antioxidant capacity of the moringa seed cake, moringa leaf powder, and raw propolis were 1.14, 0.56, and 8.56 mg Trolox/g DM, respectively. However, such differences were not evident in the fermentation fluid. In conclusion, the supplementation of moringa seed cake desirably modulates rumen microbial activities related to protein and carbohydrate metabolism.
Violence Against Paramedics: Protocol for Evaluating 2 Years of Reports Through a Novel, Point-of-Event Reporting Process

Background Violence against paramedics has been described as a serious public health problem with the potential for significant physical and psychological harm, but the organizational culture within the profession encourages paramedics to consider violence as just “part of the job. ” Therefore, most incidents of violence are never formally documented. This limits the ability of researchers and policy makers to develop strategies that mitigate the risk and enhance paramedic safety. Objective Following the development and implementation of a novel, point-of-event violence reporting process in February 2021, our objectives are to (1) estimate the prevalence of violence and generate a descriptive profile for incidents of reported violence; (2) identify potentially high-risk service calls based on characteristics of calls that are generally known to the responding paramedics at the point of dispatch; and (3) explore underpinning themes, including intolerance based on gender, race, and sexual orientation, that contribute to incidents of violence. Methods Our work is situated in a single paramedic service in Ontario, Canada. Using a convergent parallel mixed methods approach, we will retrospectively review 2 years of quantitative and qualitative data gathered from the External Violence Incident Report (EVIR) system from February 1 2021 through February 28, 2023. The EVIR is a point-of-event reporting mechanism embedded in the electronic patient care record (ePCR) developed through an extensive stakeholder engagement process. When completing an ePCR, paramedics are prompted to file an EVIR if they experienced violence on the call. Our methods include using descriptive statistics to estimate the prevalence of violence and describe the characteristics of reported incidents (Objective 1), logistic regression modeling to identify high-risk service calls (Objective 2), and qualitative content analysis of incident report narratives to identify underpinning themes that contribute to violence (Objective 3). Results As of January 1, 2023, 377 paramedics—approximately 1 in 5 active-duty paramedics in the service—have filed a total of 975 violence reports. Early analysis suggests 40% of reports involved a physical assault on the reporting paramedic. Our team is continuing to collect data with more fulsome analyses beginning in March 2023. Our findings will provide much-needed epidemiological data on the prevalence of violence against paramedics in a single paramedic service, its contributing themes, and potential risk factors. Conclusions Our findings will contribute to a growing body of literature demonstrating that violence against paramedics is a complex problem that requires a nuanced understanding of its scope, risk factors, and contributing circumstances. Collectively, our research will inform larger, multisite prospective studies already in the planning stage and inform organizational strategies to mitigate the risk of harm from violence.

The shock wave structure by model equations of capillarity

We investigate the influence of the capillarity terms on the shock wave structure. To this end we compare the shock structures derived from the viscosity-capillarity model and from the Navier-Stokes equations, i.e. the viscosity model. Let A and e characterize the values of the capillarity and viscosity effects, respectively. First, we prove that if the ratio A/e 2 > 1 then the viscosity-capillarity shock waves are oscillatory, whereas the viscosity waves are never such. Thirdly, to investigate the intermediate case of A/e 2 ≃ 1 we study numerically so-called impending shock splitting. This effect consists in that the shock profile has two inflection points, under suitably chosen data, instead of one, what is usual.
InterEvo-TR: Interactive Evolutionary Test Generation With Readability Assessment

Automated test case generation has proven to be useful to reduce the usually high expenses of software testing. However, several studies have also noted the skepticism of testers regarding the comprehension of generated test suites when compared to manually designed ones. This fact suggests that involving testers in the test generation process could be helpful to increase their acceptance of automatically-produced test suites. In this paper, we propose incorporating interactive readability assessments made by a tester into EvoSuite, a widely-known evolutionary test generation tool. Our approach, InterEvo-TR, interacts with the tester at different moments during the search and shows different test cases covering the same coverage target for their subjective evaluation. The design of such an interactive approach involves a schedule of interaction, a method to diversify the selected targets, a plan to save and handle the readability values, and some mechanisms to customize the level of engagement in the revision, among other aspects. To analyze the potential and practicability of our proposal, we conduct a controlled experiment in which 39 participants, including academics, professional developers, and student collaborators, interact with InterEvo-TR. Our results show that the strategy to select and present intermediate results is effective for the purpose of readability assessment. Furthermore, the participants’ actions and responses to a questionnaire allowed us to analyze the aspects influencing test code readability and the benefits and limitations of an interactive approach in the context of test case generation, paving the way for future developments based on interactivity.
Molecular Classification of Appendiceal Adenocarcinoma

PURPOSE Appendiceal adenocarcinomas (ACs) are rare, histologically diverse malignancies treated as colorectal cancers despite having distinct biology and clinical behavior. To guide clinical decision making, we defined molecular subtypes of AC associated with patient survival, metastatic burden, and chemotherapy response. PATIENTS AND METHODS A comprehensive molecular analysis was performed in patients with AC to define molecular subtypes. Associations between molecular subtype and overall survival, intraoperative peritoneal cancer index, and first-line chemotherapy response were assessed adjusting for histopathologic and clinical variables using multivariable Cox proportional hazards, linear regression, and logistic regression models. RESULTS We defined distinct molecular lineages of mucinous appendiceal adenocarcinoma (MAAP) from co-occurring mutations in GNAS, RAS, and TP53. Of 164 MAAP tumors, 24 were RAS-mutant (mut) predominant (RAS-mut/GNAS-wild-type [wt]/TP53-wt) with significantly decreased mutations and chromosomal alterations compared with tumors with GNAS mutations (GNAS-mut predominant) or TP53 mutations (TP53-mut predominant). No patient with RAS-mut predominant subtype metastatic MAAP died of cancer, and overall survival in this subgroup was significantly improved compared with patients with GNAS-mut (P = .05) and TP53-mut (P = .004) predominant subtypes. TP53-mut predominant subtypes were highly aneuploid; increased tumor aneuploidy was independently (P = .001) associated with poor prognosis. The findings retained significance in patients with any metastatic AC. RAS-mut predominant metastases exhibited reduced peritoneal tumor bulk (P = .04) and stromal invasion (P < .001) compared with GNAS-mut or TP53-mut predominant tumors, respectively. Patients with RAS-mut predominant MAAP responded more to first-line chemotherapy (50%) compared with patients with GNAS-mut predominant tumors (6%, P = .03). CONCLUSION AC molecular patterns identify distinct molecular subtypes: a clinically indolent RAS-mut/GNAS-wt/TP53-wt subtype; a chemotherapy-resistant GNAS-mut predominant subtype; and an aggressive, highly aneuploid TP53-mut predominant subtype. Each subtype exhibits conserved clinical behavior irrespective of histopathology.
Isomorphism of modular group algebras of totally projective abelian groups

Throughout in this work, F and Fp will denote an arbitrary field of charF = p and a simple field of charF, = p (i.e. the fiinite field with pelements), respectively, and G will denote an arbitrary abelian group which will be written multiplicatively. For G such a group, Go denotes its torsion part with pprimary component Gp. For the most part, the notations and terminology from the abelian group theory are standard and are in agreement with L.Fuchs [9]. Besides, ordinary are also the notations and terminologies to the set theory [15] and commutative group algebras theory 1141. For the last theory, as well iB for the important techniques, the reader is also referred to [16,17] or to some other original sources such as [5] and [4,6]. Now, for n a natural number, it will be tacitly assumed throughout that <, are primitive qn-th roots of unity in the algebraic cover Fp of Fp, where q # p is a prime integer. Then, following Mollov (cf. [2]), the set s, (Fp) = {n E IN U ( 0 ) ( IFp(<,) # Fp(<n+l)) we shall call a spectrum of IFp about q.
Near-infrared CCD photometry of Cygnus X-3

The first photometric observations capable of resolving the 4.8-hr period at near-infrared wavelengths of the extraordinary X-ray source Cygnus X-3 have been obtained using a CCD at the Perkins 1.8-m telescope. The data show that the 4.8-hr light curve at I band exhibits a variety of forms ranging from being relatively quiescent within the photometric errors to showing fluctuations exceeding 1 mag on time scales of tens of minutes to several hours. There is a suggestion that the variations may be correlated with phase of the 4.8-hr infrared and X-ray period, but the pulsed fraction of the I band fluctuations is about 90 percent compared to 10-25 percent for the infrared and X-ray variations. If confirmed, these vairations may represent important new information concerning the origin of the 4.8-hr cycle and of the nature of the binary system. The mean I-magnitude of Cygnus X-3 is found to be 20.0 + or - 0.2. 23 refs.
DFT Simulation-Based Design of 1T-MoS2 Cathode Hosts for Li-S Batteries and Experimental Evaluation

The main challenge in lithium sulphur (Li-S) batteries is the shuttling of lithium polysulphides (LiPSs) caused by the rapid LiPSs migration to the anode and the slow reaction kinetics in the chain of LiPSs conversion. In this study, we explore 1T-MoS2 as a cathode host for Li-S batteries by examining the affinity of 1T-MoS2 substrates (pristine 1T-MoS2, defected 1T-MoS2 with one and two S vacancies) toward LiPSs and their electrocatalytic effects. Density functional theory (DFT) simulations are used to determine the adsorption energy of LiPSs to these substrates, the Gibbs free energy profiles for the reaction chain, and the preferred pathways and activation energies for the slow reaction stage from Li2S4 to Li2S. The obtained information highlights the potential benefit of a combination of 1T-MoS2 regions, without or with one and two sulphur vacancies, for an improved Li-S battery performance. The recommendation is implemented in a Li-S battery with areas of pristine 1T-MoS2 and some proportion of one and two S vacancies, exhibiting a capacity of 1190 mAh/g at 0.1C, with 97% capacity retention after 60 cycles in a schedule of different C-rates from 0.1C to 2C and back to 0.1C.
On the median residual lifetime and its aging properties: A characterization theorem and applications

This paper is devoted to study several aspects of the median residual life function (MERLF). In reliability studies, it is well known that, although the MERLF have several advantages over the mean residual life function (MRLF), the MRLF has the good property of uniquely determine a life distribution whereas either the median residual life function (MERLF) or an α‐percentile residual life do not have such good property. We shall give a characterization result where knowledge of both the MERLF and the survival function on an interval does uniquely determine the distribution. Moreover, in order to apply this characterization in practical situations, we propose a method to estimate the necessary information of the survival function. Relationships between analytical properties of the survival function and its associated MERLF are also obtained. Bryson and Siddiqui [J Am Statist Assoc 64 (1969), 1472–1483] proved relationships among seven criteria for aging, out of which two contained the MRLF (decreasing MRLF and net decreasing MRLF). In this paper, we prove that the same pattern of relationships holds if the MRLF is replaced by the MERLF. We also examine the aging criteria corresponding to an increasing MERLF and show that there is no relation between the behavior (increasing or decreasing) of the MERLF and of the MRLF. © 2005 Wiley Periodicals, Inc.
