ObjectiveThe COVID-19 pandemic has placed unprecedented pressure on front-line healthcare workers, leading to poor health status, especially diet quality. This study aimed to develop a diet quality prediction model and determine the predictive effects of personality traits, socioeconomic status, lifestyles, and individual and working conditions on diet quality among doctors and nurses during the COVID-19 pandemic.MethodsA total of 5,013 doctors and nurses from thirty-nine COVID-19 designated hospitals provided valid responses in north China in 2022. Participants’ data related to social-demographic characteristics, lifestyles, sleep quality, personality traits, burnout, work-related conflicts, and diet quality were collected with questionnaires. Deep Neural Network (DNN) was applied to develop a diet quality prediction model among doctors and nurses during the COVID-19 pandemic.ResultsThe mean score of diet quality was 46.14 ± 15.08; specifically, the mean scores for variety, adequacy, moderation, and overall balance were 14.33 ± 3.65, 17.99 ± 5.73, 9.41 ± 7.33, and 4.41 ± 2.98, respectively. The current study developed a DNN model with a 21–30–28-1 network framework for diet quality prediction. The DNN model achieved high prediction efficacy, and values of R2, MAE, MSE, and RMSE were 0.928, 0.048, 0.004, and 0.065, respectively. Among doctors and nurses in north China, the top five predictors in the diet quality prediction model were BMI, poor sleep quality, work–family conflict, negative emotional eating, and nutrition knowledge.ConclusionDuring the COVID-19 pandemic, poor diet quality is prevalent among doctors and nurses in north China. Machine learning models can provide an automated identification mechanism for the prediction of diet quality. This study suggests that integrated interventions can be a promising approach to improving diet quality among doctors and nurses, particularly weight management, sleep quality improvement, work-family balance, decreased emotional eating, and increased nutrition knowledge.

Published: October 2023

ObjectiveThe present study investigated the clinical potential of managing anxiety during dental procedures to reduce acute attacks in patients with hereditary angioedema (HAE). HAE is a rare disease, little known to physicians and dentists, but with an increased hospitalization rate over the years. HAE is due to a deficiency/dysfunction of the C1 esterase inhibitor, leading to increased vascular permeability. Recommendations for HAE management include long-term and short-term prophylaxis and treatment of acute attacks, but the importance of anxiety control is underestimated.Materials and methodsThe authors reviewed the literature to provide the scientific community with an overview of possible protocols for managing anxiety in dental practice and their effectiveness. Management can be used in prosthetics, periodontal and implant surgery, endodontics, and oral surgery.DiscussionsOur analysis shows that although there are few articles in the indexed literature, protocols for managing anxiety in HAE patients in dentistry will become increasingly prevalent in the daily clinical practice of dentists due to its benefits.ConclusionsThe benefits and better control of intraoperative complications and risks may lead clinicians to use sedation, assessment, or anxiety control techniques in daily clinical practice to reduce such attacks. Clinical relevance: This study suggests that controlling and managing anxiety can help prevent and reduce acute angioedema attacks.
Simulations of Compression Ramp Shock Wave/Turbulent Boundary Layer Interaction Controlled via Steady Jets at High Reynolds Number
Authors: Dai Tingkai , Zhang Bo 
Published: October 2023

Shock wave/turbulent boundary layer interaction (SBLI) is one of the most common physical phenomena in transonic wing and supersonic aircraft. In this study, the compression ramp SBLI (CR-SBLI) was simulated at a 24° corner at Mach 2.84 using the open-source OpenFOAM improved delayed detached eddy simulation (IDDES) turbulence model and the “Rescaling and Recycling” method at high Reynolds number 1.57×106. The results of the control effect of the jet vortex generator on CR-SBLI showed that the jet array can effectively reduce the length of the separation zone. The simulation results of different jet parameters are obtained. With the increasing jet angle, the reduction in the length of the separation zone first increased and then decreased. In this work, when the jet angle was 60°, the location of the separation point was x/δ=−1.48, which was smaller than other jet angles. The different distances of the jet array also had a great influence. When the distance between the jet and the corner djet=70 mm, the location of the separation point x/δ=−1.48 was smaller than that when djet=65/60 mm. A closer distance between the jet hole and the corner caused the vortex structures to squeeze each other, preventing the formation of a complete vortex structure. On the other hand, when the jet was farther away, the vortex structures could separate effectively before reaching the shock wave, resulting in a better inhibition of SBLI. The simulation primarily focused on exploring the effects of the jet angle and distance, and we obtained the jet parameters that provided the best control effect, effectively reducing the length of the CR-SBLI separation zone.

Published: October 2023

Background and Objectives: Tamarind-seed polysaccharide (TSP) and hyaluronic acid (HA) have mucoadhesive properties that improve drug absorption and delay in drug elimination from the ocular surface. We aimed to evaluate TSP/HA-containing formulation for its efficiency in dry-eye symptoms induced by adverse environments and the interaction between mucomimic polymer and tear-film parameters. Materials and Methods: The participants were exposed to 5% relative humidity (RH) in a Controlled Environment Chamber (CEC) under constant room temperature (21 °C). Tear-film parameters were assessed at 40% RH and 5% RH. Rohto Dry Eye Relief drops were used in the two treatment modalities, protection (drops instilled before exposure to the dry environment) and relief (drops instilled after exposure to the dry environment). The HIRCAL grid, Servomed EP3 Evaporimeter, and Keeler’s TearScope-Plus were used to screen for non-invasive tear break-up time (NITBUT), tear evaporation rate, and lipid-layer thickness (LLT) using protection and relief treatment methodology. Results: LLT was found to be significantly thinner at 5% RH compared with at 40% RH (p = 0.007). The median LLT dropped from 50–70 nm (grade 3) at 40% RH to 10–50 nm (grade 2) at 5% RH. TSP/HA eye drops significantly augment LLT in both treatment modalities, protection (p = 0.01) and relief (p = 0.004) at 5% RH. The mean evaporation rate doubled from 40.93 at 40% RH to 82.42 g/m2/h after exposure to 5% RH. In protection mode, the TSP/HA allowed the average evaporation rate to be much lower than when no TSP/HA was used at 5% RH (p < 0.008). No alteration in evaporation rate was recorded when the TSP/HA drop was used after exposure (relief). The mean NITBUT was reduced from 13 s in normal conditions to 6 s in the dry environment. Instillation of TSP/HA eye drops resulted in significant improvement (p = 0.006) in tear stability, where the NITBUT increased to 8 s in both protection (before exposure) and relief (after exposure) (p = 0.001). Although improved, these values were still significantly lower than NITBUT observed at 40% RH. Conclusions: Significant protection of tear-film parameters was recorded post instillation of TSP/HA eye drop under a desiccating environment. Both treatment methods (protection and relief) were shown to be effective. The presence of TSP/HA enhances the effectiveness of teardrops in protecting the tear-film parameters when exposed to adverse environments.

Aim. To study the efficacy and safety of laparoscopic mechanical renal denervation.Methods. Thirty sheep with mean weight 92.3±2.1 kg were divided in 2 groups: control group (group I, n=15) and mechanical laparoscopic renal denervation group (group II, n=15). The follow-up period was 6 months. The following parameters were assessed: blood pressure in response to high-frequency electrical intraluminal stimulation, creatinine, blood urea nitrogen test (BUN), damage to the renal arteries according to the result of angiography, the degree of destruction of nerve fibers according to histological examination.Results. All animals were alive during the entire observation period. The creatinine and BUN were within the normal ranges during the observation period. Angiography of the renal arteries did not reveal iatrogenic stenotic lesions. After 6 months in group 2 there was hypertensive response of blood pressure to high-frequency electrical stimulation (in-creased systolic blood pressure ∆70.27±5.31 (p>0.005), diastolic blood pressure ∆49.87±6.05 (p>0.005)). After 6 months, the animals were euthonised, further histological examination was completed. Histological examination: in the group II, there was swelling and vacuolization of the nerve fiber without signs of demyelination.Conclusions. Laparoscopic mechanical renal denervation is a safe technique. However, the hypotensive effect is short-term.

Aim. To evaluate the possibility to use parameters of global, segmental longitudinal left ventricle (LV) strain and LV mechanical dispersion (MD) as new possible markers of malignant ventricular tachyarrhythmias (MVT) in patients with structural heart disease and reduced and intermediate LV ejection fraction (EF).Methods. The study included 113 patients (105 male, age 66 [59;73] year) with ischemic (n=89) or non-ischemic (n=24) dilated cardiomyopathy and LVEF<50%, implanted cardioverter-defibrillators, cardiac resynchronization therapy devices-defibrillators, pacemakers or documented MVT. All patients underwent transthoracic echocardiography with an assessment of speckle-tracking echocardiography parameters (global and segmental longitudinal LV strain, LV MD). Comparative univariate and ROC-analyses were performed between patients with and without MVT separately for patients with LVEF <35% (n=60) and LVEF 36-50% (n=53) LVEF.Results. The group of patients with LVEF ≤35% with MVT (n=30) was characterized by lower values of longitudinal strain of the basal segment of the LV septum wall (-5[-6,5;-0,5] vs -6,8[-11;-4.4], р=0,01, respectively) and the middle segment of the LV inferior wall (-3[-6;2] vs -6[-9;-1,5], р=0,04, respectively). The group of patients with LVEF 36-50% with MVT (n=33) was distinguished by a large value of LV end-diastolic volume (166,5[146,3;193] vs 156[133,8;165,5], р=0,04, respectively). The greater values of LV MD were noted in both groups of patients with MVT. The optimal cut-off value of LV MD was 120 ms (area under the ROC curve 0.817, sensitivity-73,3%, specificity-80%) for patients with LVEF≤35%, and 90 ms (area under the ROC curve 0.761, sensitivity-72.7%, specificity-75%) for patients with LVEF 36-50%.Conclusion. Speckle-tracking echocardiography parameters may serve as additional markers of increased risk of MVT in patients with structural heart disease and impaired LVEF. Only LV MD is useful for risk stratification of MVT in patients with either reduced or intermediate LVEF.

Published: October 2023

Abstract
We investigated the resonant tunneling of a two-spin system through the double quantum dots in Al–N-implanted silicon tunnel FETs (TFETs) by electrical-transport measurements and Landau–Zener–Stückelberg–Majorana interferometry with and without magnetic fields. Our experimental results revealed the coexistence of spin-conserving and spin-flip tunneling channels in the two-spin system in non-zero magnetic fields. Additionally, we obtained the spin-conserving/spin-flip tunneling rates of the two-spin system through the double quantum dots in the TFET. These findings will improve our understanding of the two-spin system in silicon TFET qubits and may facilitate the coherent control of quantum states through all-electric manipulation.

АНАЛІТИЧНИЙ РОЗРАХУНОК ГЛИБИНИ ПОШИРЕННЯ ТЕМПЕРАТУРНОЇ ХВИЛІ ПРИ ПОБУДОВІ ГЕОТЕРМАЛЬНИХ ТЕПЛОНАСОСНИХ СИСТЕМ
Authors: Морозов Ю. П. , Зур’ян О. В. 
Published: October 2023

У процесі вирішення завдань ґрунтового акумулювання й вилучення теплоти з приповерхневих шарів Землі, виникає потреба одержати інформацію щодо глибини добових та річних змін температури в ґрунті, яка визначає шар земної поверхні, що активно взаємодіє з навколоземною атмосферою. У холодну пору року температура в ній знижується, а в теплу – підвищується. Відомо, що ефективність теплонасосної системи залежить як від різниці температур на виході з конденсатора теплового насоса та вході в його випарник, так і від стабільності температури джерела теплової енергії. Температура на вході у випарник теплового насоса визначається температурою ґрунту в місці встановлення колектора теплової енергії. Відомо, що найбільш економічно рентабельною є інсталяція геотермальних теплообмінників, розташованих горизонтально в ґрунті на невеликій глибині, за рахунок менших витрат на земельні роботи та відсутності необхідності буріння глибоких свердловин. Водночас ці системи найвразливіші до перепаду температур, що відбувається в приповерхневих шарах. Тож виникає потреба в дослідженні теплофізичних процесів, що відбуваються в ґрунті під впливом екзогенних факторів. Відомо, що температура ґрунту має добову та річну періодичність. Ступінь нагрівання ґрунту залежить від його теплопровідності, під якою розуміють здатність ґрунту проводити тепло з більш нагрітих шарів у шари менш нагріті. А коливання температури ґрунту може суттєво залежати від рослинного покриву ґрунту, характеру та висоти його протягом року. Разом з тим залишаються недостатньо дослідженими системи теплообмінник–ґрунт, ефективність використання яких безпосередньо залежить від розподілу температури в ґрунті та факторів, які на цей розподіл впливають. Головною особливістю системи добування геотермальної теплової енергії є поєднання технічних і природного елементів таких систем. При цьому природнє джерело теплової енергії перебуває в середовищі, яке малодоступне для спостережень. Метою дослідження є розроблення прикладної методології як сукупності принципів та підходів математичного моделювання на основі запропонованого математичного апарату аналітичного розрахунку глибини поширення температурної хвилі при побудові геотермальних теплонасосних систем. Основний математичний апарат для опису таких процесів включає в себе диференціальні рівняння, що враховують залежність температури від часу та просторових координат. Мають перспективу подальші дослідження щодо розрахунку можливості застосування сонячної системи для отримання теплової енергії для зменшення девіації температури теплоносія на вході в випарник теплового насоса, що поступає від горизонтального ґрунтового теплообмінника, змонтованого в ґрунті нижче глибин промерзання та вище нейтрального шару температур.

Spectral Retrieval with JWST Photometric data: a Case Study for HIP 65426 b
Authors: Wang 王 Ji 吉 
Published: October 2023

Abstract
Half of the JWST high-contrast imaging objects will only have photometric data as of Cycle 2. However, to better understand their atmospheric chemistry that informs formation origin, spectroscopic data are preferred. Using HIP 65426 b, we investigate to what extent planet properties and atmospheric chemical abundance can be retrieved with only JWST photometric data points (2.5–15.5 μm) in conjunction with ground-based archival low-resolution spectral data (1.0–2.3 μm). We find that the data is consistent with an atmosphere with solar metallicity and C/O ratios at 0.40 and 0.55. We rule out 10× solar metallicity and an atmosphere with C/O = 1.0. We also find strong evidence of silicate clouds but no sign of an enshrouding featureless dust extinction. This work offers guidance and cautionary tales on analyzing data in the absence of medium-to-high-resolution spectral data.

Abstract
In this paper, using the latest Pantheon+ sample of Type Ia supernovae, baryon acoustic oscillation measurements, and observational Hubble data, we carry out a joint constraint on the Hubble constant H
0, the spatial curvature ΩK, and the sound horizon at the end of the drag epoch r
d. To be model-independent, four cosmography models—i.e., the Taylor series in terms of redshift y
1 = z/(1 + z),

, and the Padé approximants—are used without the assumption of a flat Universe. The results show that H
0 is anticorrelated with ΩK and r
d, indicating that smaller ΩK or r
d would be helpful in alleviating the Hubble tension. The values of H
0 and r
d are consistent with the estimate derived from the Planck cosmic microwave background data based on the flat ΛCDM model, but H
0 is in 2.3 ∼ 3.0σ tension with that obtained by Riess et al. in all these cosmographic approaches. Meanwhile, a flat Universe is preferred by the present observations under all approximations except the third order of y
1 and y
2 of the Taylor series. Furthermore, according to the values of the Bayesian evidence, we found that the flat ΛCDM remains to be the most favored model by the joint data sets, and the Padé approximant of order (2,2), the third order of y
3 and y
1 are the top three cosmographic expansions that fit the data sets best, while the Taylor series in terms of y
2 are essentially ruled out.
