Variable Time-Steps in the Numerical Implementation of Viscoelastic Fractional Models for Laminated Glass
Authors: Santi Lorenzo , Royer-Carfagni Gianni 
Published: January 2024

Abstract
Numerical approaches are elaborated to calculate the rheological response of laminated glass beams, whose viscoelastic interlayer is modeled via fractional calculus. This mathematical description is very effective when the relaxation function of the polymer can be expressed by continuously connected branches of power laws, as is the case for most materials used to laminate glass. The classical approach uses the Grünwald–Letnikov approximation of fractional derivatives, but it requires constant time-steps, which would become very large to reasonably cover the entire observation time, thus losing accuracy. The use of the L1 algorithm with increasing time-steps is proposed, which is well suited to the power law character of the relaxation function. This allows to follow the long-term creep response, providing a better approximation when needed. The method is implemented for beams laminated with viscoelastic interlayers whose relaxation is described by four branches of power laws, to cover most practical cases. Numerical experiments show their advantages over the Grünwald–Letnikov approach for characterizing the long-term structural response.
National Collegiate Athletic Association Coaches’ Beliefs Toward Seeking Mental Health Services for Themselves: Instrument Validation and Exploratory Investigation
Authors: Tolentino Kim , Raabe Johannes 
Published: January 2024

While the environment in which National Collegiate Athletic Association coaches operate makes them susceptible to mental health issues, many do not seek professional help. The Reasoned Action Approach posits that attitudes, perceived behavioral control, and perceived norms shape intentions for help-seeking behaviors. This study was designed to: (a) validate two commonly utilized instruments measuring psychological help-seeking beliefs for use with National Collegiate Athletic Association coaches; (b) assess coaches’ attitudes, perceived behavioral control, and perceived norms toward seeking mental health services for themselves; and (c) examine differences in beliefs based on gender, race, coaching role, age, and coaching experience. N = 1,424 National Collegiate Athletic Association Division I, II, and III coaches participated. Confirmatory factor analyses indicated the Inventory of Attitudes Toward Seeking Mental Health Services provides valid and reliable measurements for participants’ beliefs toward seeking services for themselves. Participants reported moderately positive attitudes, perceived behavioral control, and perceived norms. Male coaches indicated significantly lower positive beliefs than female coaches.

ABSTRACT

Taniborbactam (TAN; VNRX-5133) is a novel bicyclic boronic acid β-lactamase inhibitor (BLI) being developed in combination with cefepime (FEP). TAN inhibits both serine and some metallo-β-lactamases. Previously, the substitution R228L in VIM-24 was shown to increase activity against oxyimino-cephalosporins like FEP and ceftazidime (CAZ). We hypothesized that substitutions at K224, the homologous position in NDM-1, could impact FEP/TAN resistance. To evaluate this, a library of codon-optimized NDM K224X clones for minimum inhibitory concentration (MIC) measurements was constructed; steady-state kinetics and molecular docking simulations were next performed. Surprisingly, our investigation revealed that the addition of TAN restored FEP susceptibility only for NDM-1, as the MICs for the other 19 K224X variants remained comparable to those of FEP alone. Moreover, compared to NDM-1, all K224X variants displayed significantly lower MICs for imipenem, tebipenem, and cefiderocol (32-, 133-, and 33-fold lower, respectively). In contrast, susceptibility to CAZ was mostly unaffected. Kinetic assays with the K224I variant, the only variant with hydrolytic activity to FEP comparable to NDM-1, confirmed that the inhibitory capacity of TAN was modestly compromised (IC
50
0.01 µM vs 0.14 µM for NDM-1). Lastly, structural modeling and docking simulations of TAN in NDM-1 and in the K224I variant revealed that the hydrogen bond between TAN’s carboxylate with K224 is essential for the productive binding of TAN to the NDM-1 active site. In addition to the report of NDM-9 (E149K) as FEP/TAN resistant, this study demonstrates the fundamental role of single amino acid substitutions in the inhibition of NDM-1 by TAN.
Power of microbes: utilization of improvised microbial fuel cell (IMFC) as an interdisciplinary learning activity in teaching bioelectricity
Authors: Robledo Dave Arthur R. , Roleda Lydia S. 
Published: January 2024

ABSTRACT

Bioelectricity is an interdisciplinary concept that encompasses the fields of chemistry, physics, and biology. It is the scientific study of membrane transport mechanisms that govern the formation and dissipation of ion gradients. Teaching and learning across disciplines, such as bioelectricity, are known among science teachers to be challenging and complex. One of the critical problems is that only a few teaching materials and learning resources specifically support interdisciplinary teaching, especially in science. This paper described the development of an improvised microbial fuel cell (iMFC) as an alternative activity that addresses scientific concepts of cellular respiration, reduction-oxidation reaction, and electricity generation in an interdisciplinary approach. In this activity, students designed, constructed, and tested their iMFCs. The learning gains of the students were measured using parallel pretest/post-test and analyzed using descriptive statistics and dependent
t
-tests. The perceptions of teachers and students on using the iMFC activity in teaching-learning bioelectricity were obtained from a survey questionnaire and interviews. Results revealed that the iMFC activity significantly improved students’ learning gains in bioelectricity, for the topics cellular respiration (
t
(239)=45.03;
P
< 0.01), reduction-oxidation reaction (
t
(239)=39.85;
P
< 0.01), and electricity (
t
(239)=31.1;
P
< 0.01), with computed normalized gains of 0.45, 0.50, and 0.39, respectively. Furthermore, seven subthemes emerged from the teachers’ and students’ perceptions, namely, knowledge acquisition, student engagement, academic emotions, affordability, student satisfaction, distractions, and cleanliness. Overall results indicated that the iMFC activity can be an effective teaching material for providing an authentic learning experience in a multidisciplinary topic like bioelectricity. Future investigations on the iMFC activity and its impact on other aspects of learning, such as students’ motivation, self-efficacy, and engagement, are recommended.

Simultaneous measurements on cosmic curvature and opacity using latest HII regions and H(z) observations

Published: January 2024

AbstractThe different spatial curvatures of the universe affect the measurement of cosmological distances, which may also contribute to explaining the observed dimming of type Ia supernovae. This phenomenon may be caused by the opacity of the universe. Similarly, the opacity of the universe can lead to a bias in our measurements of curvature. Thus, it is necessary to measure cosmic curvature and opacity simultaneously. In this paper, we propose a new model-independent method to simultaneously measure the cosmic curvature and opacity by using the latest observations of HII galaxies acting as standard candles and the latest Hubble parameter observations. The machine learning method-Artificial Neural Network is adopted to reconstruct observed Hubble parameter H(z) observations. Our results support a slightly opaque and flat universe at $$1\sigma $$

Survey on Recommender Systems for Biomedical Items in Life and Health Sciences
Authors: Pato Matilde , Barros Márcia , Couto Francisco M. 
Published: January 2024

The generation of biomedical data is of such magnitude that its retrieval and analysis have posed several challenges. A survey of recommender system (RS) approaches in biomedical fields is provided in this analysis, along with a discussion of existing challenges related to large-scale biomedical information retrieval systems. We collect original studies, identify entities and models, and discuss how knowledge graphs (KGs) can improve results. As a result, most of the papers used model-based collaborative filtering algorithms, most of the available datasets did not follow the standard format < user, item, rating >, and regarding qualitative evaluations of RSs use mainly classification metrics. Finally, we have assembled and coded a unique dataset of 60 papers — Sur-RS4BioT, available for download at DOI:10.34740/kaggle/ds/2346894
A phylogeny of Carrerapyrgota Aczél (Diptera, Pyrgotidae)
Authors: Cordeiro Maria Leidiane Alves , Mello Ramon Luciano 
Published: January 2024

Carrerapyrgota Aczél, 1956 is a Neotropical Diptera genus within Pyrgotidae. Currently, the genus comprise four species: C. miliaria Aczél, 1956 (type species), C. personata (Lutz & Lima, 1918), C. aczeli Mello, Lamas & Rafael, 2010, and C. bernardii Mello, Lamas & Rafael, 2010. This study investigates the phylogenetic relationships among Carrerapyrgota species, aiming to establish their monophyly as a genus. To achieve this, we conducted phylogenetic analyses based on 22 external morphological characters of adults, emploing the principle of parsimony. Analyses using both equal and implied character weighting support the monophyly of the genus, based on the following apomorphies: absence of the postscutellum, R₂₊₃ with spurious apical vein, lower calypter with a longitudinal row of bristles, and the presence of a posterior longitudinal groove on the female fore femur. The species C. aczeli, C. bernardii, and C. miliaria form a monophyletic group, supported by the synapomorphic condition of a spot on the forehead. Within this group, C. bernardii and C. miliaria are sister species, sharing the synapomorphic condition of a less sclerotized M vein, after dm-cu compared to the anterior region, as well as the homoplastic condition of a spot on the median occipital sclerite. This phylogenetic analysis reaffirms the synonymy proposed by Bernardi (1990), which treats Anapyrgota Steyskal, 1967, as a junior synonym of Carrerapyrgota. The evolutionary relationship among the species of the genus is represented as (C. personata (C. aczeli (C. bernardii, C. miliaria))). Furthermore, this study includes an updated distributional map for the genus, featuring the first record of Pyrgotinae in the Andean region.

Baseline Stroke Risk and Efficacy of Dual-Antiplatelet Therapy: A Post Hoc Analysis of the POINT Trial
Authors: Daghlas Iyas , Johnston S. Claiborne , Easton J. Donald , Kim Anthony S. 
Published: January 2024

BACKGROUND:
High-risk transient ischemic attacks and minor ischemic strokes are followed by a variable risk of ischemic stroke. We aimed to determine how baseline stroke risk modified the efficacy of clopidogrel-aspirin (referred to here as dual-antiplatelet therapy [DAPT]) for transient ischemic attack and minor ischemic stroke.

METHODS:

We performed an unplanned secondary analysis of the POINT trial (Platelet-Oriented Inhibition in New Transient Ischemic Attack and Minor Ischemic Stroke). We first evaluated the associations of the CHA
2
DS
2
-VASc and stroke prognosis instrument II (SPI-II) scores with the risk of incident ischemic stroke and major hemorrhage (intracranial hemorrhage or major systemic hemorrhage). We then tested for heterogeneity of the relative and absolute treatment effect of DAPT relative to aspirin across low- and high-risk patient subgroups.

RESULTS:

A total of 4841 trial participants were included in this analysis, with 2400 participants assigned to treatment with short-term DAPT and 2430 participants to treatment with aspirin and placebo. The dichotomized SPI-II score, but not the CHA
2
DS
2
-VASc score (
P
=0.18), was associated with the risk of incident ischemic stroke. A high-risk SPI-II score (>3) was associated with greater risk of incident ischemic stroke (hazard ratio of incident ischemic stroke relative to low-risk SPI-II score of 1.84 [95% CI, 1.44–2.35];
P
<0.001) and numerically greater risk of major hemorrhage though not meeting statistical significance (hazard ratio, 1.80 [95% CI, 0.90–3.57];
P
=0.10). The relative risk reduction with DAPT was similar across SPI-II strata (
P
interaction
=0.31). The absolute risk reduction for ischemic stroke with DAPT compared with aspirin was nearly 4-fold higher (2.80% versus 0.76%; number needed to treat, 31 versus 131) in the high-risk SPI-II stratum relative to the low-risk stratum. The absolute risk increase for major hemorrhage with DAPT compared with aspirin was 3-fold higher (0.84% versus 0.30%; number needed to harm, 119 versus 331) in the high-risk SPI-II stratum relative to the low-risk stratum.

CONCLUSIONS:
Stratification by baseline stroke risk identifies a patient subgroup that derives greater absolute benefit from treatment with DAPT.

Published: January 2024

BACKGROUND:
Atrial fibrillation (AF) is a frequent underlying cause of cryptogenic stroke (CS) and its detection can be increased using implantable cardiac monitoring (ICM). We sought to evaluate different risk scores and assess their diagnostic ability in identifying patients with CS with underlying AF on ICM.

METHODS:

Patients with CS, being admitted to a single tertiary stroke center between 2017 and 2022 and receiving ICM, were prospectively evaluated. The CHA
2
DS
2
-VASc, HAVOC, Brown ESUS-AF, and C
2
HEST scores were calculated at baseline. The primary outcome of interest was the detection of AF, which was defined as at least 1 AF episode on ICM lasting for 2 consecutive minutes or more. The diagnostic accuracy measures and the net reclassification improvement were calculated for the 4 risk scores. Stroke recurrence was evaluated as a secondary outcome.

RESULTS:

A total of 250 patients with CS were included, and AF was detected by ICM in 20.4% (n=51) during a median monitoring period of 16 months. Patients with CS with AF detection were older compared with the rest (
P
=0.045). The median HAVOC, Brown ESUS-AF, and C
2
HEST scores were higher among the patients with AF compared with the patients without AF (all
P
<0.05), while the median CHA
2
DS
2
-VASc score was similar between the 2 groups. The corresponding C statistics for CHA
2
DS
2
-VASc, HAVOC, Brown ESUS-AF, and C
2
HEST for AF prediction were 0.576 (95% CI, 0.482–0.670), 0.612 (95% CI, 0.523–0.700), 0.666 (95% CI, 0.587–0.746), and 0.770 (95% CI, 0.699–0.839). The C
2
HEST score presented the highest diagnostic performance based on C statistics (
P
<0.05 after correction for multiple comparisons) and provided significant improvement in net reclassification for AF detection (>70%) compared with the other risk scores. Finally, stroke recurrence was documented in 5.6% of the study population, with no difference regarding the 4 risk scores between patients with and without recurrent stroke.

CONCLUSIONS:

The C
2
HEST score was superior to the CHA
2
DS
2
-VASc, HAVOC, and Brown ESUS-AF scores for discriminating patients with CS with underlying AF using ICM.
Mixed-Reality-Based Teleoperation Grasping Control
Authors: Zheng Dekun , Wang Ting , Jian Gao , Li Liang , Ji Xiangjun , Madani Kurosh 
Published: January 2024

Abstract
Traditionally, teleoperation means that the system sends a series of signal commands from the master while the slave manipulator receives and realizes the desired control operations. For the purpose of implementing more dexterous and complex tasks, we propose a novel framework with dual-hand master teleoperation systems under time-varied delays. In this paper, we emphasize studying the bilateral grasping teleoperation control, as the time delay causes a communication outage. Combining a wave-variable structure with a four-channel framework, an event-trigger-based bilateral sliding mode teleoperation control and an adaptive neural network are designed to effectively achieve master-slave trajectory tracking. In the virtual 3D environment, we created a mixed-reality interface based on dual-hand master teleoperation control that effectively responded to the two Omni manipulators' position transformation of the virtual manipulator. The time delay between the real slave force feedback and the virtual interface is addressed by designed event-trigger-based control in order to efficiently reduce the impact of time communication outage. The system's stability is analyzed and robot experiments are performed. From the experimental results, the telepresence platform innovatively applied virtual force feedback to reveal the soft target grasping and to accurately estimate the interactive force, enabling sensorless force feedback control.
Evaluation of Parametric Tropical Cyclone Surface Winds over the Eastern Australian Region
Authors: O’Grady Julian , Ramsay Hamish , McInnes Kathleen , Gregory Rebecca 
Published: January 2024

Abstract
Hazard studies based on thousands of synthetic tropical cyclone (TC) events require a validated model representation of the surface wind field. Here, we assess three different TC parametric vortex models with input from four along-track parameter studies of the TC size and shape, based on statistical formulation of the relationships to observed TC intensity, geographic location, and forward transition speed. The 12 model combinations are compared to in situ 10-min observed surface mean wind speeds for 10 TCs that made landfall over Queensland, Australia, which occurred over the period 2006–17. Empirical wind reduction factors to reduce gradient winds to the surface are recalculated for the more recent TCs at both offshore (ocean, small islands, reefs, and moorings) and onshore (land) locations. To improve the wind comparisons over ocean and land, a secondary reduction factor was developed based on an inland decay function. Pearson correlations for the unadjusted modeled peak wind speed from 118 instances of a TC passing a weather station sit between a range of 0.57 and 0.65 for the 12 model combinations. Using the secondary reduction factor based on the inland decay function increases the range of correlation to 0.74–0.81. Based on the assessment of the instances of peak surface wind speed correlations, bias, and root-mean-square error, along with the correlation 48 h around the peak, the top-ranked performing model combination for the region was an along-track parameter study with a double-vortex model, both previously tested for the South Pacific basin.

Significance Statement
When assessing tropical cyclone hazards, users are presented with several simplified parametric models to describe the surface wind field of tropical cyclones. These parametric models are used routinely for risk assessment of cyclonic winds, as well as for input to surge and wave models used in coastal hazard assessments. Differences between the models include the formulation of the parametric cyclone model, the way winds above the boundary layer are specified at the surface and along-track parameters that describe the cyclones’ size and shape. Of the 12 model combinations investigated in this study, the top-ranked performing model combination for the region was an along-track parameter equation with a double-vortex model, which were both tested previously for the South Pacific basin. Analysis is performed to show unadjusted modeled winds overestimate observed 10-min surface winds over the ocean by around 13% (median) and over land by around 73.9% (median), which is resolved in this study with a secondary empirical wind reduction factor. These findings will support future modeling of tropical cyclone winds for multiple applications, including regional risk assessment and coastal hazard studies.
