Abstract
Optoelectronic and spinoptronic technologies benefit from flexible and tunable coherent light sources combining the best properties of nano- and material-engineering to achieve favorable properties such as chiral lasing and low threshold nonlinearities. In this work we demonstrate an electrically wavelength- and polarization-tunable room temperature polariton laser due to emerging photonic spin–orbit coupling. For this purpose, we design an optical cavity filled with both birefringent nematic liquid crystal and an inorganic perovskite. Our versatile growth method of single CsPbBr3 inorganic perovskite crystals in polymer templates allows us to reach strong light–matter coupling and pump-induced condensation of exciton–polaritons resulting in coherent emission of light. The sensitivity of the liquid crystal to external voltage permits electrical tuning of the condensate energy across 7 nm; its threshold power, allowing us to electrically switch it on and off; and its state of polarization sweeping from linear to locally tilted circularly polarized emission.

Abstract
Chemical warfare agents (CWAs) are very toxic and dangerous to all forms of life. With the purpose of protecting environment and human health, it is essential to identify and eliminate these threats quickly and effectively. B38 nanocage as a sensor is rarely discussed therefore the detection of harmful CWAs (phosgene and thiophosgene) by using the B38 nanocage has been examined using density functional theory (DFT) parameters. Optimized geometries, adsorption energies, NCI, NBO, FMO and QTAIM studies have been used to analyze the interactions between CWAs and the B38 nanocage. The adsorption energy values indicate that CWAs are adsorbed on the B38 nanocage in a stable manner and the reaction is exothermic. The complex T-S@B38-B have the greatest conductivity, lowest stability and maximum sensitivity due to its narrow energy gap of 1.9648 eV while complex T-S@B38-6r, with the highest energy gap of 1.9988 eV is the most stable. The global reactivity parameters indicate that the complex T-S@B38-B has the highest electrophilicity index, the lowest chemical hardness and the highest chemical softness and resultantly leads to highest sensitivity. Van der Waals forces are present between the B38 nanocage and CWAs as shown by NCI and QTAIM studies. The formation of new energy level in PDOS of B38 results into the interaction of CWAs with the surface of B38. Nanocage sensing capacity is evaluated by measuring E
g value, sensitivity and recovery time of the complex. B38 has the highest sensitivity and shortest recovery time for T-S@B38-B and P-Cl@B38-B complex with 5.90 × 10−3 and 2.78259 × 10−12 s values which results the B38 nanocage is more effective sensor for detecting CWAs. Consequently, B38 nanocage is recommended as fine future sensor for the sensing of phosgene and thiophosgene.
A Method for Identifying Sports Behaviors in Sports Adversarial Project Training Based on Image Block Classification under the Internet of Things
Authors: Tan Li 
Published: February 2024

Abstract
There is a need to devise intelligent methods for motion-based image classification to produce accurate results for correct judgment. Existing methods cannot use the image block classification method to recognize the motion behavior of antagonistic sports training, and it is the need of the hour to devise newer methods. The recognition result is not ideal when using the traditional methods. This paper proposes an image block classification method for antagonistic sports training behavior recognition. It classifies the noise sources, quantifies the influence degree of each noise source effectively, and adjusts the noise factor in the denoising method for different noise sources and the specific weight of different noise sources. The adaptive denoising of different noise types of antagonistic sports training image sequences is realized. By using the combination of key frame template selection method and image segmentation method for behavior representation, the features are extracted well. The feature extraction is done on an image region according to the proportion of the number of foreground pixels in each block of the template to the number of pixels in the block. The feature vector is used to form the template. Aiming at the behavior representation and feature extraction based on the features of skeleton joint points, image block classification is used to extract the coordinates of skeleton joint points during human movement. K-means clustering is used to transform them into symbol sequences to represent behavior features that are used for antagonistic sports training behavior recognition. Simulation results show that the proposed method can obtain ideal recognition results and outperforms the existing methods.

Authors: Jiang Donglin 
Published: February 2024

Abstract
Aiming at the problem that traditional methods cannot meet the problem of synchronous positioning of multi-mobile robots in different motion states, a synchronous positioning method of multi-mobile robots based on visual simultaneous localization and mapping (SLAM) algorithm is proposed. Analyze the general model of SLAM problem, realize visual SLAM feature detection through scale invariant feature transform algorithm, and match image features based on active vision. A multi-mobile robot motion state estimation model is constructed, an octree model is used to construct a multi-robot synchronous localization map, and the camera pose tracking is realized by using the oriented fast accelerated segment test and rotated binary robust independent elementary features points that are not in the target bounding box. The three-dimensional points in the environment recovered by visual SLAM separate the background target and the moving target, and match the corresponding target in the previous frame through the feature to realize the synchronous positioning of the multi-mobile robot. The experimental results show that the method can realize the synchronous positioning of multi-robots under the state of multi-robot linear motion, curvilinear motion and mixed motion, and the positioning accuracy is high.

: SARS COV-2 vaccination was a global effort to tackle the Covid-19 pandemic. During the vaccination drive, several concerns were raised about the potential adverse effects of the Covid-19 vaccines, which included the impact on menstruation and fertility in women. This study aimed to assess experiences of Indian Women with covid vaccination and its effects on their menstruation. A prospective web-based survey was conducted targeting women aged 18years and above and who had taken atleast one dose of the covid vaccine. : The total number of responses received were 363. After excluding those with missing details, 342 respondents were included in the analysis. The mean age of the participants was 38.02 ± 7.8 years. 68.1% of the respondents (233/342) reported no change in the periodicity of their cycles post vaccination and 79.5% (272/342) reported no change in the menstrual flow. Forty three women (12.6%) reported experiencing heavy flow post vaccination. In this group which experienced heavy menses, 81.5% (35/43) reported that the heavy menses was self-limiting and did not require any treatment. 9.3% (4/43) of these symptomatic women recorded that short term treatment was sought. Another 9.3% of women reported persisting menstrual changes, at the time of the survey, despite taking prescribed treatment. It was also noted that the changes in menstrual cycles were significantly more in vaccinated nulliparous women.: Covid vaccination appears to have no or little impact on menstrual cycles in two-thirds of the women taking the vaccine. 31.9% of the women in the survey reported some change in their menstrual timing or flow. Most changes were self -limiting. About 1% (4/342) may have longer standing menstrual impact, requiring treatment.

: To report a case series on corneal trauma induced by forceps assisted vaginal delivery.: Case records of six patients who had clinical features suggestive of corneal trauma induced by forceps delivery were retrospectively reviewed and analysed. Vertical to oblique corneal Descemet’s membrane (DM) tears were noted in all 6 patients which included 2 males and 4 females. Right eye was involved in all patients and one patient had bilateral involvement. The age of presentation ranged from 5 to 39 years. Three patients had visual acuity better than 6/18 and three had worse than 6/18 in their affected eyes. All patients had corneal astigmatism in the range of 1.75 to 8 diopters. : A complicated vaginal delivery should be anticipated at the earliest by the obstetrician and an apt decision on the mode of delivery has to be attempted in order to prevent avoidable ocular trauma, especially in forceps assisted vaginal deliveries. All neonates who are born by forceps assisted vaginal delivery require mandatory referral to an ophthalmologist to rule out any ocular trauma. Early intervention can prevent irreversible vision loss due to amblyopia.

Objective: Road traffic crashes are a significant health problem worldwide, causing injury, disability, and death. This study aims to identify associated factors with intensive care unit (ICU) admission and mortality among road traffic accident victims using data from a trauma registry.

Methods: This descriptive study examined 368 road traffic accident patients in the national trauma registry system from March 2021 to March 2023. Following the objectives of the study, a checklist was created that included information on age, gender, marital status, level of education, injury severity score (ISS), Glasgow coma scale (GCS), and abbreviated injury scale (AIS). The factors associated with ICU admission and mortality among road traffic accident victims were found significant according to univariate and multivariable logistic regression analyses results.
Results: 87.8% of the 368 patients included in this study were men, with a mean age of 33.54±18.95 years. Ten patients (2.71%) of total died, and 46 (12.5%) needed to be admitted to the ICU. In-hospital mortality and gender were not significantly associated (P=0.081). However, univariate logistic regression revealed several factors significantly associated with in-hospital mortality, including GCS<8 (OR: 60.05, 95% CI: 11.67,309), ISS>16 (OR: 11.39, 95% CI: 2.67,48.55), ICU admission (OR: 5,01, 95% CI: 1.36,18.50), underwent surgery (OR: 0.055, 95% CI: 0.014,0.223), respiratory rate (OR: 0.726, 95% CI: 0.630,0.836), O2 saturation (OR: 0.906, 95% CI: 00.852,0.963), systolic blood pressure (OR: 0.910, 95% CI:0.865,0.957) and temperature (OR: 0.932, 95% CI: 00.891,0.975). Furthermore, the odds of ICU admission was found to be increased with an ISS>16 (OR: 2072.12, 95% CI: 17.29,50644.09), being a pedestrian (OR: 366.53, 95% CI: 31.44,389.85), GCS<8 on admission (OR: 87.64, 95% CI: 29.04,264.43), smoking (OR: 11.92, 95% CI: 1.45,97.64), drug usage before the accident (OR: 11.47, 95% CI: 7.09,18.56), being a motorcyclist (OR: 5.72, 95% CI: 1.06,29.22), age (OR: 1.19, 95% CI: 1.05,1.34) and the time duration between the event and admission (OR: 1.01, 95% CI: 1.003,1.02).

Conclusion: This study underscores the critical role of timely and effective medical interventions, including surgical procedures, in improving the outcomes of road accident victims. It also highlights the need for targeted preventive measures and interventions for high-risk groups pedestrians and motorcyclists.
