Knowledge, Attitude and Conspiracy Beliefs of Healthcare Workers in Lebanon towards Monkeypox

The emergence of a monkeypox (MPOX) outbreak in 2022 represented the most recent recognizable public health emergency at a global level. Improving knowledge and attitude towards MPOX, particularly among healthcare workers (HCWs), can be a valuable approach in public health preventive efforts aiming to halt MPOX virus spread. The aim of the current study was to evaluate the knowledge and attitude of HCWs in Lebanon towards MPOX and to assess their conspiratorial attitude towards emerging virus infections (EVIs). The current study was based on a cross-sectional online survey distributed via Google Forms during September–December 2022 implementing a convenience sampling approach. The final study sample comprised a total of 646 HCWs: physicians (n = 171, 26.5%), pharmacists (n = 283, 43.8%), and nurses (n = 168, 26.0%), among others (n = 24, 3.7%). Variable defects in MPOX knowledge were detected, with a third of the participants having MPOX knowledge above the 75th percentile (n = 218, 33.7%). Satisfactory attitude towards MPOX (>75th percentile) was observed in less than a third of the participants (n = 198, 30.7%), while a quarter of the study sample endorsed conspiracy beliefs towards EVIs at a high level (>75th percentile, n = 164, 25.4%). Slightly more than two thirds of the participants agreed that MPOX vaccination should be used in disease prevention (n = 440, 68.1%). Better levels of MPOX knowledge and attitude were significantly associated with postgraduate education and older age. Physicians had significantly higher MPOX knowledge compared to other occupational categories. Less endorsement of conspiracies towards EVIs was significantly associated with male sex, occupation as a physician, and postgraduate education. Higher MPOX knowledge was associated with better attitude towards the disease. The current study showed unsatisfactory MPOX knowledge among Lebanese HCWs. Educational efforts can be valuable to improve the attitude towards the disease. Despite the relatively low level of embracing conspiracy beliefs regarding EVIs among HCWs in this study compared to previous studies, this area should be considered based on its potential impact on health-seeking behavior.
Association Between Change in A1C and Use of Professional Continuous Glucose Monitoring in Adults With Type 2 Diabetes on Noninsulin Therapies: A Real-World Evidence Study

This retrospective analysis examined the association between change in A1C and professional continuous glucose monitoring (p-CGM) use in patients with type 2 diabetes and poor glycemic control who were not using insulin. Data from 15,481 eligible patients (p-CGM users n = 707 and p-CGM nonusers n = 14,774) showed a greater decrease in A1C from baseline to the end of follow-up for p-CGM users, and differences favored p-CGM users regardless of whether they started insulin therapy during the follow-up period. These findings suggest that people with type 2 diabetes who have poor glycemic control using multiple noninsulin therapies may benefit from p-CGM, which can reduce A1C over a 6-month period compared with usual care.
Electron and hole impact ionization coefficients in InP determined by photomultiplication measurements

The electron and hole ionization coefficients α and β in (100) InP have been determined through analysis of photomultiplication data on p+‐n and n+‐p junctions grown by liquid phase epitaxy (LPE). A special device structure is described which allows reproducible thinning of the substrate in order to achieve pure carrier injection from either side of the p‐n junction. By fabricating wafers with depletion layer doping levels from 1.2×1015 to 1.2×1017 cm−3, α and β have been determined over a wider range of electric fields than previously reported. The ratio of β/α decreases from 4.0 to 1.3 as the electric field is increased from 2.4 to 7.7×105 V/cm.
Warming drives poleward range contractions of Beringian endemic plant species at high latitudes

Species are expected to disperse poleward in response to climate change. For species that are endemic to the high latitudes, this implies that many in the future would face a “no‐where‐to‐go” situation as they are currently occupying the northernmost portion of the continent. Further, because endemism may arise from a combination of physical barriers, climate and geological history, the persistence of many species may require spatial matching of multiple environmental factors within a limited dispersal space. Thus, it is not clear how endemic species might spatially adjust their distributions in response to climate change and whether there are future climate change refugia for these species.
The Relative Efficiency of Regression and Simple Unit Predictor Weights in Applied Differential Psychology

A very common problem in the behavioral and social sciences is the prediction of the standing of a person or thing on one variable, usually designated the criterion, from his or its standing on a number of other variables, usually called the predictors. Leastsquared error multiple regression weights are most commonly used in weighting the predictors into a composite. These weights, which minimize, over the cases in the sample, the sum of the squared deviations of the observed from the predicted criterion score, are calculated from the normal equations which express the minimization conditions (Anderson, 1958). The fitting of the regression weights to the idiosyncracies of the initial sample leads to a decrease in effectiveness when these weights are applied to a new sample in which these particular idiosyncracies are not present. This &dquo;shrinkage&dquo; is often substantial in practical situations (e.g., see: Kurtz, 1948; Cureton, 1950; and Kirkpatrick, 1951), especially when the initial sample is small. And small samples, as Lawshe and Schucker (1959) point out, are the rule rather than the exception in many areas of applied psychology. Certain other approaches to the weighting problem produce
Calculation of Complete Absorption and Intensity of Optical Radiation Spectrum of HeI (λ= 5875Å) with Fine Structure

Theoretical calculations which account for the complete absorption and intensity for the optical radiation He I (λ= 5875 A) spectral line with fine structure of the transition 23P2,1,0 - 33D3,2,1 during He nanosecond discharge are presented. For different values of the absorption parameter (χ 0? ), the absorption quantity A of the three components distorted as a result of reabsorption multiple process has been numerically obtained and graphically presented. The theoretical results for small values of χ 0? (≤4) give a good agreement with the experimental data in literature.
Baroclinic flow over a mountain ridge

Abstract Flow incident on a mountain ridge with a linear vertical windshear is studied for a Boussinesq, adiabatic, inviscid fluid on the f-plane. A scale analysis indicates that the semigeostrophic approximation of a geostrophic mountain-parallel wind holds for sufficiently shallow mountain slopes if the Rossby number squared is small. In such a limit, the equation for the vertical displacement of a fluid parcel is elliptic if there is forward shear (wind increasing with height) or weak backward shear (wind decreasing with height) but hyperbolic if there is strong backward shear such that the incident wind vanishes at some level in the flow. Steady-state results indicate that forward shear weakens the cold-core geostrophic mountain anticyclone predicted by barotropic theory while weak backshear strengthens it. This behavior arises from the warm- (cold-) air advection in the forward (backward) shear case. While the total ageostrophic flux of mass across the mountain peak is greater for the forward shear c.
Bias Correction and Multiensemble in the NAEFS Context or How to Get a “Free Calibration” through a Multiensemble Approach

Abstract Previous studies have shown that the raw combination (i.e., the combination of the direct output model without any postprocessing procedure) of the National Centers for Environmental Prediction (NCEP) and Meteorological Service of Canada (MSC) ensemble prediction systems (EPS) improves the probabilistic forecast both in terms of reliability and resolution. This combination palliates the lack of reliability of the NCEP EPS because of the too small dispersion of the predicted ensemble and the lack of probabilistic resolution of the MSC EPS. Such a multiensemble, called the North American Ensemble Forecast System (NAEFS), especially shows bias reductions and dispersion improvements that could only come from the combination of different forecast errors. It is then legitimate to wonder whether these improvements in terms of biases and dispersions, and by extension the skill improvements, are only due to the balancing between opposite model errors. In the NAEFS framework, bias corrections “on the fly,”.
Impact of intra-aortic balloon counterpulsation on all-cause mortality among patients with Takotsubo syndrome complicated by cardiogenic shock: results from the German-Italian-Spanish (GEIST) registry

Abstract Aims Takotsubo syndrome (TTS) is an acute and reversible left ventricular dysfunction and can be complicated by cardiogenic shock (CS). However, few data are available on optimal care in TTS complicated by CS. Aim of this study was to evaluate short- and long-term impact of intra-aortic balloon pumping (IABP) on mortality in this setting. Methods and results In a multi-centre, international registry on TTS, 2248 consecutive patients were enrolled from 38 centres from Germany, Italy, and Spain. Of the 2248 patients, 212 (9.4%) experienced CS. Patients with CS had a higher prevalence of diabetes (27% vs. 19%), male sex (25% vs. 10%), and right ventricular involvement (10% vs. 5%) (P < 0.01 in all cases). Forty-three patients with CS (20% of 212) received IABP within 8 h (interquartile range 4–18) after admission. No differences in terms of age, gender, cardiovascular risk factors, and admission left ventricular ejection fraction were found among patients with and without IABP. There were no significant differences in terms of 30-day mortality (16% vs. 17%, P = 0.98), length of hospitalization (18.9 vs. 16.7 days, P = 0.51), and need of invasive ventilation (35% vs. 41%, P = 0.60) among two groups: 30-day survival was not significantly different even after propensity score adjustment (log-rank P = 0.73). At 42-month follow-up, overall mortality in patients with CS and TTS was 35%, not significantly different between patients receiving IABP and not (37% vs. 35%, P = 0.72). Conclusions In a large multi-centre observational registry, the use of IABP was not associated with lower mortality rates at short- and long-term follow-up in patients with TTS and CS.
“The Soft Bigotry of Low Expectations”: Perceptions of Teacher Expectations Among Black Families in a Suburban School

Abstract Building upon literature that has shown that Black students hold definitive beliefs about their teachers’ expectations and knowing these notions have impact on Black student achievement, we explore the experiences within a school district where diversity and inclusion efforts have been ongoing. The participants of this study were high-achieving students and their parents, a nuance that provides depth to understanding Black families’ perceptions of teacher expectations. Critical Race Theory (CRT) served as the theoretical framework and the tenets of permanence of racism, interest convergence, critique of liberalism, and whiteness as property, were employed as categorical themes to centralize the focus on how the families made meaning of their educational experiences through a CRT lens. Findings revealed that the participants were subject to unjust, low expectations that created and maintained a racial hierarchy and an anti-Black ideation on the part of teachers and school authorities. Implications include the need for teachers to raise their awareness of how their actions are interpreted, their role in creating a culture of mistrust, and the need to counter individual level and institutional racialized structures.
Modeling of Heat Transfer and Kinetics of Physical Vapor Transport Growth of Silicon Carbide Crystals

Wide-bandgap silicon carbide (SiC) substrates are needed for fabrication of electronic and optoelectronic devices and circuits that can function under high-temperature, high-power, high-frequency conditions. The bulk growth of SiC single crystal by physical vapor transport (PVT), modified Lely method involves sublimation of a SiC powder charge, mass transfer through an inert gas environment, and condensation on a seed. Temperature distribution in the growth system and growth rate profile on the crystal surface are critical to the quality and size of the grown SiC single crystal. Modeling of SiC growth is considered important for the design of efficient systems and reduction of defect density and micropipes in as-grown crystals. A comprehensive process model for SiC bulk growth has been developed that incorporates the calculations of radio frequency (RF) heating, heat and mass transfer and growth kinetics. The effects of current in the induction coil as well as that of coil position on thermal field and growth rate have been studied in detail. The growth rate has an Arrhenius-type dependence on deposition surface temperature and a linear dependence on the temperature gradient in the growth chamber.
Quantitative evaluation of the reduction of distortion and metallic artifacts in magnetic resonance images using the multiacquisition variable‑resonance image combination selective sequence

Magnetic resonance imaging (MRI) is superior to computed tomography (CT) in determining changes in tissue structure, such as those observed following inflammation and infection. However, when metal implants or other metal objects are present, MRI exhibits more distortion and artifacts compared with CT, which hinders the accurate measurement of the implants. A limited number of reports have examined whether the novel MRI sequence, multiacquisition variable-resonance image combination selective (MAVRIC SL), can accurately measure metal implants without distortion. Therefore, the present study aimed to demonstrate whether MAVRIC SL could accurately measure metal implants without distortion and whether the area around the metal implants could be well delineated without artifacts. An agar phantom containing a titanium alloy lumbar implant was used for the present study and was imaged using a 3.0 T MRI machine. A total of three imaging sequences, namely MAVRIC SL, CUBE and magnetic image compilation (MAGiC), were applied and the results were compared. Distortion was evaluated by measuring the screw diameter and distance between the screws multiple times in the phase and frequency directions by two different investigators. The artifact region around the implant was examined using a quantitative method following standardization of the phantom signal values. It was revealed that MAVRIC SL was a superior sequence compared with CUBE and MAGiC, as there was significantly less distortion, a lack of bias between the two different investigators and significantly reduced artifact regions. These results suggested the possibility of utilizing MAVRIC SL for follow-up to observe metal implant insertions.
Solar granulation properties derived from three different time series

We need automatic pattern recognition algorithms to extract a large statistical sample of granules from high spatial and temporal resolution images series of photospheric fields. In this paper, we present the new Two-level Structure Tracking (TST) algorithm, based on a two-level representation of granulation, which allows us to monitor the characteristics of identified photospheric structures during their duration. TST is also able to retrieve horizontal velocity maps from measured granule displacements. Direct comparison of the results from different works describing granular evolution is often not possible as discrepancies stemming from the use of different procedures or from different data cannot be distinguished. Here, three different solar granulation broadband time series, acquired at THEMIS in July 1999, at NSO-DST in October 1996, and at SVST in June 1995, with different spatial and temporal resolutions, are coherently analyzed via the same TST procedure, allowing direct comparison of the results. Among the obtained results, we confirm the dynamical heterogeneity of photospheric small scale structures pointed out by granular lifetime histograms, characterized by a stretched exponential function. Furthermore, by monitoring the breaking-up of a granule and the movements of its neighbours and of its fragments, we found evidence of how an exploding granule may produce a divergence signal on spatial and temporal mesogranular scales.
Patterns of symptom change measured using the EXACT diary associated with prescription of corticosteroids or antibiotics in COPD exacerbations

Background: Selection of treatment for a COPD exacerbation may vary according to physician habit and patient choice, but no studies have linked worsening of specific symptoms to the choice of treatment for the exacerbation. We used EXACT electronic diary data from a trial of extrafine formoterol/beclomethasone in COPD [Wedzicha Respir Med 2014;108:1153] to examine change in symptoms in patients receiving corticosteroids (CS) or antibiotics (AB) for an exacerbation. Methods: Data from both treatment arms were pooled. EXACT scores were aligned using the day the exacerbation was reported (Day 0). Changes in EXACT total and domain scores for breathlessness, chest symptoms and cough & sputum were calculated as the difference between peak (average of days 0-3) and baseline (average of days -21/-8). Change was compared (t-test) for any CS use (regardless of AB use) vs none and for any AB use (regardless of CS use) vs none. Results: Data from 449 events were available. The breathlessness score worsened significantly more in patients given CS (p=0.007), whereas cough & sputum worsened significantly more in patients given AB (p<0.001). [Figure][1] Conclusions: Patients with a greater increase in cough & sputum were more likely to receive AB for an exacerbation; those with greater worsening of breathlessness were more likely to receive CS. This, of course, does not validate such treatment choices. [1]: pending:yes
On the Marginal Automorphisms of a Group

Let W be a nonempty subset of a free group. We call an automorphism α of a group G a marginal automorphism if x −1α(x) ∈ W*(G) for each x ∈ G, where W*(G) is the marginal subgroup of G. In this article, we give some results on marginal automorphisms of a group.
Theory of Donor States in Silicon

By using the recently measured effective masses for $n$-type Si, ${m}_{1}=0.98$ $m$ and ${m}_{2}=0.19$ m, approximate solutions of the resulting effective mass Schroedinger equation are obtained. The accuracy of the solutions was tested in the limiting cases where $\frac{{m}_{2}}{{m}_{1}}=1 \mathrm{and} 0$ respectively. The nature of the resulting states and their degeneracy is discussed in some detail, taking into account the fact that the conduction band of Si has six equivalent minima. Experimentally measured ionization energies show that the effective mass theory is seriously in error in the case of the ground state. This error is attributed to failure of the effective mass theory near the donor nucleus, and allowance for this failure is made in the case of higher states. This leads finally to a theoretical spectrum for the electrons bound by P, As, or Sb donors.
Single-Feed Dual-Band Dual-Mode and Dual-Polarized Microstrip Antenna based on Metamaterial Structure

A novel single-feed dual-band dual-mode and dual-polarized microstrip antenna based on metamaterial structure is proposed. The composite right/left-handed transmission line (CRLH TL) theory is used to design this antenna. Dual-mode can be obtained by exciting the antenna with a monopolar radiation in the n = 0 mode and a patch-like radiation pattern in the n = +1 mode, respectively. As the geometry of the radiating patch does not affect the infinite wavelength mode, circular polarization (CP) is obtained for the n = +1 mode by truncating the square radiating patch with the n = 0 mode, linear polarization (LP) staying unchangeable. Results of a fabricated one illustrate that this antenna is valuable in practical application for its low-profile, easy fabrication, radiation pattern selectivity and polarized diversity.
Stability of water waves

We apply some general results for Hamiltonian systems, depending on the notion of signature of eigenvalues, to determine the circumstances under which collisions of imaginary eigenvalue for the linearized problem about a travelling water wave of permanent form are avoided or lead to loss of stability, up to non-degeneracy assumptions. A new superharmonic instability is predicted and verified.

Ustekinumab-induced autoimmune hepatitis: a case report

Ustekinumab is a fully human monoclonal antibody that binds to interleukin (IL)-12/23. Ustekinumab-related liver injury (UST) is rare. There is limited data available on the potential for ustekinumab-liver interaction. We report the case of a patient from our institution followed for colitis ulcerative who developed autoimmune hepatitis (AIH) during treatment with ustekinumab. The diagnosis of autoimmune hepatitis was retained on the simplified criteria for autoimmune hepatitis. Therapeutic management consisted of stopping ustekinumab and starting corticosteroids and immunosuppressants, with regression of cytolysis at 2 months. The purpose of the article is to alert readers and encourage them to report similar cases for better knowledge of the drug.
