Authors: Wulandari Eka Suci , Ernawati Ernawati , Nuswantoro Djohar
Published: August 2021

Abstract.Background : The maternal mortality rate in Indonesia is dominated by preeclampsia as the second highest cause after bleeding. Several predictors can be categorized as risk factors that can be used to increase alertness in the care of pregnant women with severe preeclampsia to avoid complications. The purpose of this study was to study the relationship between risk factors for severe preeclampsia and its complications. Methods: This study used an observational analytic method with a case control design. The sampling technique is simple random sampling. The number of samples in this study were 80 samples, with 40 samples in each group. The case group was severe preeclampsia with one complication and the control group was severe preeclampsia without complications. Statistical analysis used was chi square and multiple logistic regression analysis. Results: The results showed that there was a significant relationship between age variables (p value = 0.001 < 0.05; OR = 5.318; CI = 2.118 – 13,356), BMI (p value = 0.002 < 0.05; OR = 6.000; CI = 1.958 – 18.384 ) and gestational age (p value = 0.039 < 0.05; OR = 2.636; CI = 1.040 – 6.685). Multiple logistic regression analysis showed that BMI (p = 0.003), age (p = 0.001) and gestational age (p = 0.048) were variables included in the final modeling of the regression analysis with the incidence of severe preeclampsia complications. Conclusion: BMI is the variable that has the strongest relationship with the incidence of severe preeclampsia complications.

Published: August 2021

AbstractBackground: Quality antenatal care in the MCH program is considered to be one of the effective efforts to reduce maternal and child morbidity and mortality. An indicator of the success of ANC services can be seen from the output produced, namely in the form of K4 coverage. According to Kotler there are 5 (five) determinants of service quality that can be used as a basis for assessing the level of customer satisfaction with the quality of service received including Tangibles, Reliability, Responsiveness, Assurance and Empathy. Method: This research method is quantitative descriptive with survey approach. The total sample of 149 pregnant women with total sampling techniques. The instrument used was a questionnaire. Data analysis uses univariate analysis. Results: The most valued statements both from each dimension namely; tangible: Midwife performance reliability: recording in the MCH handbook, responsiveness: responses to complaints, assurance: the nature of the Midwife, empathy of communication between midwives and patients. The most valued statements are enough from each dimension namely; tangible: examination room, reliability: service procedures, responsieness: midwife response to patients waiting for long queues, assurance: guarantee to service, empathy: suitability of waiting time and duration of service. Conclusion: The data shows that the majority of respondents considered the quality of antenatal services at the Tambakrejo Public Health Center to be good but still needed to be improved so that the assessment was sufficiently good.

Background: Marjolin’s ulcer is malignant lesion from scar due to burn trauma, chronic osteomyelitis, chronic inflammation, or chronic fistulae. This type of ulcer is rare, usually progressively grow on unhealed wound, accompanied by chronic trauma especially burn scar. Marjolin’s ulcer can form different types of pathologies`. Squamous cell carcinoma is the most type of histology. Previously, there was 3 Marjolin’s ulcer reported in Indonesia.Case Presentation: Reporting 3 Marjolin’s ulcer case on Dr. Soetomo General Hospital since 2008 to 2016. Two patients have history of unhealed chronic wound and one patient has history of burn injury 27 years ago. From the histopathology examination, all the results are squamous cell carcinoma. All patient undergo wide excision surgery done by surgical oncologist. All the defect is closed by flap modality. One patient’s defect is closed by latissimus dorsi flap, the other with anterolateral thigh free flap, and the latter is closed by latissimus dorsi free flap. Remain raw surface close by split thickness skin graft.Conclusion: Marjolin’s ulcer is malignant lesion from scar due to burn trauma, chronic osteomyelitis, chronic inflammation, or chronic fistulae. Marjolin’s ulcer sometimes grow become squamous cell carcinoma although require a long time. Treatment this case is same the other malignancy. Diagnosis should be confirmed by clinical, radiological, and pathological.

Palatal Fracture Fixation on Severe Panfacial Fracture: Is There Any Clinical Significance?
Authors: Prasetyo Arif Tri , Hutagalung Magda Rosalina , Zarasade Lobredia
Published: August 2021

Background: Fractures of the hard palate are infrequent. They are found in less then 10% of patients with midfacial fractures. They practically never occur in isolation and are usually part of alveolar process fractures or more complex midfacial fractures of the Le Fort type. Treatment of palatal fractures is planned and performed with the goal of restoring the transverse width of the palate, the anteroposterior projection of the maxillary arch, and the patient’s pretraumatic occlusal plane, as well as maintaining horizontal stability of the midface.Case Presentation: Reporting patient female 17 years old with panfacial fracture due to traffic accident. There was slight epidural haemorrhage on frontal area. The fractures are on upper face, midface, and lower face including the hard palate. We performed open reduction internal fixation on palate to correct the arch of the upper jaw. The other fracture site can be corrected easier. The approaches that we done are bicoronal, subsilier, and intraoral. The patient was successfully treated using bottom-up and outside-in sequence by accessing all facial injuries. Postoperatively, radiograph examination revealed good reduction and fixation of titanium plates, and physical examination revealed good functional and aesthetic outcomes.Conclusion: Palate fractures are relatively uncommon and are associated with significant rates of malocclusion and wound complications. These injuries are typically managed with plate fixation of the alveolar ridge with variable approaches to the palatal vault

Published: August 2021

Abrasion is injury to skin due to trauma that affects the surface of the epidermis or superficial epithelium, especially from friction to the depth of the dermal papillae. The basic principle of abrasion treatment is to maintain moist condition in wound surface. This study aims to compare the effectiveness of silver sulfadiazine (SSD) and gentamicin cream in the process of healing abrasions. A total of 30 samples of abrasion patients who came for treatment at the ED were sampled, and divided into 3 groups, namely wound care by providing SSD, gentamicin and tulle. The wound dimensions are assessed from the length and width measured at the 1st day, the 5th day, and the 10th day. At the 10th day assessment, SSD was found to be more effective in healing abrasions compared to other groups. The use of SSD in abrasion wound treatment is believed to have advantages in proliferation phase where SSD is a sulfonamide class antibiotic that produces synergic effects along with silver which constantly absorbs exudates and bacteria, combines chloride tissue and several other proteins in the process of wound healing.

Background: The incidence of burns in Indonesia progressively increases with the increase in its population and industries. From January to September 2000, 158 patients were treated in the burn unit of Dr Soetomo Hospital with a mortality rate reaching 5,8%. Burns have a direct effect in causing both local and systemic changes in the body, not occurring in other injuries. In severe burns, a hypermetabolic state can occur, which increases cardiac workload and causes muscle atrophy and other morbidities. The purpose of this study is to examine the effect of propranolol on the hypermetabolic state in severely burned patients by measuring various clinical & laboratory parameters.Methods : This is an experimental study using pre and post test control group design with the objective of assessing the treatment outcome with oral propranolol given in 15 consecutive days for burn patients involving 25%- 60% TBSA. Measurements were taken three times, on day 0, 7 and 14.Results : Obtained 16 samples divided into 2 groups. In the treatment group, there was a significant decrease in CRP levels on days 0, 7 and 14 (p <0.05). The Mid Arm Circumference variable did not obtain a significant decreasing on days 0, 7 and 14. The albumin level studied showed a significant decreasing on day 0 & 7 days with a value of p = 0.045. From the comparison between the two groups, there were significant differences in CRP levels on days 0 & 14, with the mean value of the treatment group -5.12 + 2.88 and the mean value of the control group 2.86 + 7.37, and the value of p = 0.019.Conclusions: This study successfully proved that the administration of propranolol can overcome the effects of hypermetabolism which is characterized by decreasing in CRP levels.

Authors: N Priscilla Valentin , Saputro Iswinarno Doso
Published: August 2021

Background: Scalp defect with exposed bones is a serious injury that is often occurred after electrical burn injury. The coverage treatment may vary from local flap to free flap. Coverage becomes a major problem when flaps fails or is contraindicated and resulting in further morbidity. In this paper we report 1 patient with large scalp defect after electrical burn injury.Methods : In this study, we report 1 patient with large scalp defect after electrical burn, which treated in our department. Fourteen days after the electrical burn injury, surgical debridement was done by the plastic surgeon, and multiple burr holes were made by the neurosurgeon in the nonviable bone. The distance between each burr holes was 15 mm. The defect was keep moist with absorbent. The scalp defects were treated with soft tissue debridement every 3 days in the policlinics to keep the wound presented viable. To date, the wound already treated for 90 days.Results : The granulation tissue appears in between the burr holes within 14 days. After the defect was covered with granulation tissues, a further closure such as skin graft application was necessary. No postoperative infection, osteomyelitis, or cranial bone sequestration was reported in this case.Conclusions: Multiple cranial burr holes can be chosen as an alternative treatment for large scalp defect. These technique, allow the formation of a vascular bed suitable for skin grafting. This technique is safe, swift and effective for cases of extensive exposure for the skull bone expose of the periosteum following trauma.

Peat revegetation is an effort to reduce the rate of areas reduction and the decreasing of storing capability of carbon and to restore the ecological function of peatlands. The purpose of this study was to analyze the cost components of peatland revegetation activities and to analyze the cost of each peat revegetation activity component. The research location taked place in 2 (two) villages, Haur Gading District, HSU Regency, South Kalimantan. The components of revegetation costs were grouped into: transportation costs, tools and mateials, payment and other costs. Data obtained from surveys and field observations and interviews. The data analysis used were a tabulation matrix and a comparison of each cost component for revegetation activities from the 2 compared villages. The total cost of Village A peatland revegetation activities is 10,851,018/ha. The characteristics of the community in Village A are very participatory and willing to cooperate with outside parties so that revegetation activities in this Village run well. The very high value of mutual cooperation and the desire to put common interests first became the basis for their actions. Village B revegetation activity costs Rp.12,117,883.00/ha. The very large costs involved in the procurement of seedlings due to the addition of 3,500 seedlings/21ha as replacements for dead, damaged or lost seedlings. The difference in the cost of revegetation activities is IDR 1,266,865/ha. This shows that a high level of participation and cooperation is able to reduce the cost of revegetation of peatlands.
Climate Change, Uncertainty and Policy
Authors: Hopster Jeroen
Published: August 2021

While the foundations of climate science and ethics are well established, fine-grained climate predictions, as well as policy-decisions, are beset with uncertainties. This chapter maps climate uncertainties and classifies them as to their ground, extent and location. A typology of uncertainty is presented, centered along the axes of scientific and moral uncertainty. This typology is illustrated with paradigmatic examples of uncertainty in climate science, climate ethics and climate economics. Subsequently, the chapter discusses the IPCC’s preferred way of representing uncertainties and evaluates its strengths and weaknesses from a risk management perspective. Three general strategies for decision-makers to cope with climate uncertainty are outlined, the usefulness of which largely depends on whether or not decision-makers find themselves in a context of deep uncertainty. The chapter concludes by offering two recommendations to ease the work of policymakers, faced with the various uncertainties engrained in climate discourse.
Level lines of a polynomial in the plane
Authors: Bruno Alexander Dmitrievich , Batkhin Alexander Borisovich
Published: August 2021

We propose a method for computing the position of all level lines of a real polynomial in the real plane. To do this, it is necessary to compute its critical points and critical curves, and then to compute critical values of the polynomial (there are finite number of them). Now finite number of critical levels and one representative of noncritical level corresponding to a value between two neighboring critical ones enough to compute. We propose a scheme for computing level lines based on polynomial computer algebra algorithms: Gröbner bases, primary ideal decomposition. Software for these computations are pointed out. Nontrivial examples are considered.

Lower-Limb Ischemia at Birth Because of Spontaneous Arterial Thrombosis
Authors: Vaidya Sandeep V. , Pinto Deepika A. , Mehta Rujuta , Agashe Mandar V. , Aroojis Alaric
Published: August 2021

Case:

A full-term neonate presented with right lower extremity ischemia at birth because of spontaneous thrombosis of the right common iliac artery. He was initially managed with supportive treatment, anticoagulation, and dressings; however, advanced gangrenous changes precluded salvage of the ischemic limb. A guillotine amputation was performed at day 15 of life, and the stump went on to heal well by secondary intention.

Conclusion:

Thromboembolic events occurring in infancy are well-recognized phenomena; however, it is far rarer to encounter a neonate born with “congenital gangrene”. We discuss the etiology, approach to diagnosis, and treatment of this rare but devastating condition.
Expression and secretion of active Moringa oleifera coagulant protein in Bacillus subtilis
Authors: Arnett Clint , Lange Justin , Boyd Ashley , Page Martin , Cropek Donald
Published: August 2021

Cationic polypeptide proteins found in the seeds of the tropical plant Moringa oleifera have coagulation efficiencies similar to aluminum and ferric sulfates without their recalcitrant nature. Although these proteins possess great potential to augment or replace traditional coagulants in water treatment, harvesting active protein from seeds is laborious and not cost-effective. Here, we describe an alternative method to express and secrete active M. oleifera coagulant protein (MO) in Bacillus subtilis. A plasmid library containing the MO gene and 173 different types of secretory signal peptides was created and cloned into B. subtilis strain RIK1285. Fourteen of 440 clones screened were capable of secreting MO with yields ranging from 55 to 122 mg/L of growth medium. The coagulant activity of the highest MO secreting clone was evaluated when grown on Luria broth, and cell-free medium from the culture was shown to reduce turbidity in a buffered kaolin suspension by approximately 90% compared with controls without the MO gene. The clone was also capable of secreting active MO when grown on a defined synthetic wastewater supplemented with 0.5% tryptone. Cell-free medium from the strain harboring the MO gene demonstrated more than a 2-fold reduction in turbidity compared with controls. Additionally, no significant amount of MO was observed without the addition of the synthetic wastewater, suggesting that it served as a source of nutrients for the effective expression and translocation of MO into the medium.
Bacterial N4-methylcytosine as an epigenetic mark in eukaryotic DNA
Authors: Rodriguez Fernando , Yushenova Irina , DiCorpo Daniel , Arkhipova Irina
Published: August 2021

In eukaryotes, 5-methylcytosine is the predominant DNA base modification, followed by N6-methyladenine. However, N4-methylcytosine (4mC) is confined to bacteria. Here we report that 4mC can serve as an epigenetic mark in eukaryotes. Bdelloid rotifers, freshwater invertebrates with transposon-poor genomes that are rich in foreign genes, lack C5-methyltransferases but encode an amino-methyltransferase, N4CMT, captured from bacteria >60 Mya. N4CMT introduces 4mC into DNA, and its chromodomain shapes the "histone-read-DNA-write" architecture together with a "DNA-read-histone-write" SETDB1/eggless H3K9me3 histone methyltransferase variant preferentially binding 4mC-DNA, to maintain 4mC and silent chromatin at transposons and tandem repeats. Our results bring the third base modification into the eukaryotic repertoire, demonstrate how non-native DNA methyl groups can reshape complex epigenetic systems to suppress transposon proliferation, and establish horizontal gene transfer as the source of regulatory innovation in eukaryotes.

Authors: Hamedi Hemad , Kamyabi-Gol ATA
Published: August 2021

Carbon fiber reinforced polymer (CFRP) materials have been effectively used as externally bonded sheets to repair damaged steel structures such as airplanes and ships. In this study, a series of double strap joints with different bonding lengths are considered and examined to experimentally and theoretically assess the effective bond length. Various models exist in the literature which are used to predict the strength of steel and CFRP joints under various loading conditions. Non-linear Lagrange stress method (NLS) which is a novel stress-based method for predicting the failure load values is presented for the first time. This approach is based on 2D and 3D linear elastic finite element analysis. Relying only on two experimental tests, the new approach proposed here can quickly and easily predict the failure load in steel/CFRP samples. In this methodology, it is assumed that the adhesive joint will fail as the normal stress along the adhesive mid-line reaches a predetermined value at a critical distance. In addition, experimental data on steel/CFRP joints gathered from the literature are compared to predictions using the NLS method. It was found that results from the theoretical predictions (NLS) were in good agreement with experimental tests conducted on double strap joints. It was also revealed that the average accuracy of the NLS method is superior to other methods such as cohesive zone model and Hart-Smith. The results revealed that under the best conditions, the NLS model is 5 times more accurate than existing models.

Published: August 2021

Endophytes have recently garnered importance worldwide and multiple studies are being conducted to understand their important role and mechanism of interaction inside plants. But before we indulge in their functions it is necessary to dig into the microbiome. This will help to get a complete picture of the microbes intrinsic to their host and understand changes in community composition with respect to their habitats. To fulfil this requirement in our study we have attempted to dissect the endophytic diversity in roots of rice plant grown across the various agro-ecological zones of West Bengal by undergoing amplicon analysis of their 16S rRNA gene. We found that the agro-ecological zones can be divided into two groups: nutrient dense (GAZ, NHZ and TTAZ) and nutrient low groups (CSZ, RLZ and VAZ). Few genera (Aeromonas, Sulfurospirillum, Uliginosibacterium, etc.) are present in samples cultivated in all the zones representing the core microbiome of rice in West Bengal while some other genera like Lactococcus, Dickeya, Azonexus, Pectobacterium, etc. are unique to specific zone. It can be concluded that understanding which particular endophytes cohabit with the internal plant environment can play an important role in endophyte-based stress management strategy.
Degradation Mechanism of Methyl Orange by Pyrite-Activated Persulfate
Authors: Liu Hui , BI Wenlong
Published: August 2021

This paper took methyl orange (MO), a typical azo dye, as the target substance to explore the degradation mechanism of pyrite (FeS2)-activated persulfate (PS) by advanced oxidation technology, and response surface methodology was used to determine the optimal dosage of FeS2 and PS. The related experiments were conducted focused on different factors and degradation mechanisms. The results showed that when the initial concentration of MO was 0.1 mM, the pyrite was 1.6 g/L and PS was 1.0 mM, the degradation rate of MO could reach 92.94% in 150 min. In the FeS2/PS system, the main free radical was sulfate radical, which contributed about 22.43% to the degradation of MO, but the hydroxyl radical contributed little. Both pH ≤ 2 and pH ≥ 10 would have an inhibitory effect on the system, and the removal effect of MO was the best at initial pH of 4. The Cl−, HCO3− and H2PO4− might play an important role in the treatment of actual wastewater. This study had shown that HCO3− in a low concentration and Cl− had little effect on the system; H2PO4− and high concentration of HCO3− could inhibit the reaction of the system. By exploring the influence of different water matrices such as tap water, river water, and distilled water, it was found that HCO3− would have a negative impact on the experiment, and the degradation effect was obviously observed when the pH was adjusted to 4. The results can provide technical support for the degradation of pyrite-activated persulfate system in printing and dyeing wastewater.
Contamination of the slit-lamp breath shield under face-masking conditions: a prospective clinical study
Authors: Sato Ken-ichi
Published: August 2021

Objective Ophthalmologists have installed breath shields on slit-lamp microscopes to block droplets produced by patients and prevent infection with severe respiratory syndrome coronavirus 2, the cause of the coronavirus disease 2019 pandemic. This study measured the contamination of one such shield used in clinical practice under face-masking conditions and examined its significance in preventing infection.Methods In this single-center prospective study, measurements were taken at an ophthalmology outpatient unit on 10 weekdays: 5 consultation days and 5 closed days. All patients were required to use face masks, including surgical masks, commercially available cloth masks, and homemade cloth masks. A breath shield, made of polyethylene terephthalate, was hung on the eyepieces of the slit-lamp microscope. Measurement areas of 25 cm2 were set on the patient-side surface of the shield, as well as on the slit-lamp table, where touching was not forbidden. Samples were collected after wiping with 78 vol% ethanol at 9 a.m., at the beginning of office hours. Touching the shield was forbidden during office hours, and the samples were collected again at 5 p.m., at the end of office hours. The total amount of adenosine triphosphate + adenosine diphosphate + adenosine monophosphate was measured as an indicator of the degree of contamination.Results Contamination of the shield had increased by the end of office hours on the consultation days, although the p-value from a paired t-test was slightly above 0.05. In contrast, on days when the department was closed, no difference was observed in the level of contamination between morning and evening. Similarly, the slit-lamp table was significantly contaminated on consultation days, whereas there was no difference in contamination between morning and evening on closed days.Conclusions This study suggests that droplets from patients can still reach the shield even when the patients are wearing a mask.

Authors: Sartin Emma B , Ruggieri Dominique G. , Diogo Adrian , O’Malley Lauren , London Lakhaya , Curry Allison E.
Published: August 2021

Objective

To determine whether and how non-driving related (NDR) license suspensions impacts affected individuals’ economic and financial stability, social and community relationships, and health and well-being.
Methods

We conducted semi-structured phone interviews with 14 adults in [BLINDED] between September 2020 and January 2021. Participants had an NDR suspension and were primarily recruited through community partners. A directed content analysis approach informed the development of the coding scheme. Coded transcripts were reviewed to identify themes.
Results

We identified five themes: loss of autonomy disrupting everyday quality of life; compromised health; employment challenges; compromised social and community relationships; and the experience of having a license suspension. Participants reported a cascade of negative consequences across several aspects of their lives; as one aspect was affected, others worsened.
Conclusion

NDR suspensions appear to create or exacerbate unemployment and financial instability, isolation, and health issues (primarily mental health and substance abuse problems).
Policy implications:

This study provides insight into how NDR suspension policies harm individuals and are potential examples of systemic racism/classism; our conclusion supports ongoing state- and federal-level efforts to end this practice.

Published: August 2021

Background: Understanding the intention of receiving COVID-19 vaccines is important to inform effective vaccination strategies. This study aimed to investigate such intention, identify the key influencing factors, and determine the most important intention predictors using a theoretically principled model. Methods: An online, cross-sectional survey method was implemented in Macao in May 2021. People aged 18 years or above and residing in Macao for 12 months prior to the study were recruited through social media. Intention to receive COVID-19 vaccines and the main constructs of the protection motivation theory and the health belief model were the main measures.Descriptive statistics, Pearson correlation and multiple linear regression were used for data analysis.Results: A total of 552 valid responses were received. Among the respondents, 79.5% aged between 25 and 54 years old, 59.4% were female, and 88% had a bachelor degree or above; 62.3% of the respondents indicated their intention to receive COVID-19 vaccination while 19.2% were hesitant and 18.5% did not have any intention. While 67.0% believed COVID-19 infection was life-threatening, only 19.0% thought they were at risk of getting infected. Control variables such as age, gender, education level, and having travel plans were significantly correlated with intention. Significant associations between intention with perceived severity, perceived susceptibility, maladaptive response reward, self-efficacy, response-efficacy, response cost, social attitude, social norm, past experience and information seeking behaviorwere identified (p<0.05). The most important positive predictors of intention were “being able to make arrangement to receive the vaccine” (β=0.333, P<0.001), “a sense of social responsibility” (β = 0.326, P<0.001), and “time off from work after vaccination” (β = 0.169, P<0.001), whereas “concerns over vaccine safety” (β = - 0.124, P < 0.001) and“relying on online resources for vaccine information” (β = -0.065, P <0.05)were negative predictors. Perceived severity was not a predictor of intention.Conclusion: Multi-component strategies to enhance health literacy that supports well-informed decision-making, increase vaccination convenience, promote social responsibility, and provide time-off incentivesareamong the key considerations in designing and improve vaccination campaigns in Macao.
Prepaid Domestic Gas Metering System & Reduction of System Loss in the Energy Sector of Bangladesh: A Case Study on Titas Gas Transmission & Distribution Company Limited
Authors: Nargis
Published: August 2021

Titas Gas Transmission and Distribution Company Limited (TGTDCL) is the largest gas transmission and distribution company in Bangladesh. The company undertook a pilot project in July 2005 to implement pre-paid metering on a limited scale. The outcomes of the pilot project are analyzed and presented in this paper. Most of the customers under the project appear to be indifferent to the new system. The revenue of TGTDCL was less compared to the same number of un-metered customers. The pilot project has a lack of design, planning, and implementation errors. Calculations are therefore made based on the assumed parameters. Clear and conclusive results regarding the reduction of gas wastage and financial benefits are hard to determine.
An inhibited laser

Published: August 2021

Traditional lasers function using resonant cavities, in which the round-trip optical path is exactly equal to an integer multiple of the intracavity wavelengths to constructively enhance the spontaneous emission rate. By taking advantage of the resonant cavity enhancement, the narrowest sub-10-mHz-linewidth laser and a 10^-16-fractional-frequency-stability superradiant active optical clock (AOC) have been achieved. However, never has a laser with atomic spontaneous radiation being destructively inhibited in an anti-resonant cavity where the atomic resonance is exactly between two adjacent cavity resonances been proven. Herein, we present the first demonstration of the inhibited stimulated emission, which is termed an inhibited laser. Compared with traditional superradiant AOCs exhibiting superiority for the high suppression of cavity noise in lasers, the effect of cavity pulling on the inhibited laser's frequency can be further suppressed by a factor of (2F/π)^2. This study of the inhibited laser will guide further development of superradiant AOCs with better stability, and may lead to new searches in the cavity quantum electrodynamics (QED) field.
