Current Perspectives in Vaginal Laxity Measurement: A Scoping Review
Authors: Aulia Indri , Valeria Michelle 
Published: June 2023

AbstractThis scoping review aimed to identify and categorize the available measurement options for vaginal laxity (VL), their indications of use, and whether these measurements can sufficiently provide objective clinical judgment for cases indicated for vaginal rejuvenation with many treatment options nowadays. Systematic searches were conducted on five electronic databases, manually searching articles' bibliographies and predetermined key journals with no date or study design limitations. We included all studies involving VL in their inclusion criteria, treatment indications, and outcome parameters. We used the Arksey and O'Malley frameworks as the guideline in writing this scoping review. Of the 9,464 articles identified, 66 articles and 11,258 subjects were included in the final analysis. The majority of studies were conducted in obstetrics and gynecology (73%), followed by plastic surgery (10%), medical rehabilitation (4.5%), dermatology (4.5%), and others (8%). Most studies originated from the North American region (30%). The following measurement tools were used: (1) interviews, (2) questionnaires, (3) physical/digital examinations, (4) perineometers, and (5) others. Our results suggested that subjective perception of laxity confirmed by directed interview or questionnaire is sufficient to confirm VL. Additional evaluation of pelvic floor muscle through digital examination or perineometer or other preferred tools and evaluation of sexual function through validated questionnaire (Female Sexual Function Index, Female Sexual Distress Scale-Revised, etc.) should follow to ensure holistic care to patients. Future research on the psychometric properties (reliability and validity) of commonly used measurements and the correlation in between subjective and objective measurements should be initiated before their clinical applications.

Published: June 2023

Objective Nasal high-frequency oscillatory ventilation (nHFOV) and synchronized nasal intermittent positive pressure ventilation (sNIPPV) yield a lower partial pressure of carbon dioxide (pCO2) after extubation than nasal continuous positive airway pressure. Our aim was to clarify which of the two was superior.
Study Design We performed a crossover randomized study to evaluate pCO2 level among 102 participants from July 2020 to June 2022. Intubated preterm and term neonates with arterial lines were randomly allocated to nHFOV–sNIPPV or sNIPPV–nHFOV sequences; their pCO2 levels were measured after 2 hours in each mode. Subgroup analyses were performed for preterm (gestational age <37 weeks) and very preterm (gestational age <32 weeks) neonates.
Results The mean gestational age (nHFOV–sNIPPV, 32.8 vs. sNIPPV–nHFOV, 33.5 weeks) and median birth weight (1,850 vs. 1,930 g) did not differ between the sequences. The mean ± standard deviation pCO2 level after nHFOV (38.7 ± 8.8 mm Hg) was significantly higher than that after sNIPPV (36.8 ± 10.2 mm Hg; mean difference: 1.9 mm Hg; 95% confidence interval: 0.3–3.4 mm Hg; treatment effect [p = 0.007] but no sequence [p = 0.92], period [p = 0.53], or carryover [p = 0.94] effects). However, the difference in pCO2 level between the sequences was not statistically significant in the subgroup analyses of preterm and very preterm neonates.
Conclusion After neonatal extubation, the sNIPPV mode was associated with a lower pCO2 level than the nHFOV mode with no significant difference in preterm and very preterm neonates.

Published: June 2023

Objective Terminating pregnancy appropriately before the intrauterine infection has progressed may have an improved prognosis for preterm infants. We evaluate how the combination of histological chorioamnionitis (hCAM) and clinical chorioamnionitis (cCAM) affects the short-term prognosis of infants.
Study Design This retrospective multicenter cohort study based on the Neonatal Research Network of Japan included extremely preterm infants born weighing <1,500 g between 2008 and 2018. Demographic characteristics, morbidity, and mortality were compared between the cCAM(−)hCAM(+) and cCAM(+)hCAM(+) groups.
Results We included 16,304 infants. The progression to cCAM in infants with hCAM was correlated with the increase in home oxygen therapy (HOT) (adjusted odds ratio [aOR], 1.27; 95% confidence interval [CI], 1.11–1.44) and persistent pulmonary hypertension of the newborn (PPHN) (1.20, 1.04–1.38). Furthermore, increased progression of the hCAM stage in infants with cCAM correlated with an increase in bronchopulmonary dysplasia (BPD; 1.05, 1.01–1.11), HOT (1.10, 1.02–1.18), and PPHN (1.09, 1.01–1.18). However, it had a negative impact on hemodynamically significant patent ductus arteriosus (hsPDA; 0.87, 0.83–0.92) and death before discharge from the neonatal intensive care unit (NICU; 0.88, 0.81–0.96).
Conclusion Progression to cCAM in infants with hCAM positively correlated with HOT and PPHN. Progression of hCAM staging in infants with cCAM further increases the prevalence of BPD and the need for HOT and PPHN while reducing the prevalence of hsPDA and death before discharge from the NICU. The effects of the progressive hCAM stage in infants with cCAM vary from positive to negative by disease.

Social preferences and well-being: theory and evidence
Authors: Iwasaki Masaki 
Published: June 2023

AbstractMany studies have shown that individuals engage in prosocial behaviors, such as pro-environmental and charitable behaviors, on the basis of their social preferences. But the nature of social preferences has not been well studied, and it has been unclear how they relate to individual well-being. It is important to clarify this linkage so that various policies and laws can maximize social welfare. This study explores the hypothesis that social preferences are in general positively correlated with subjective well-being and that individuals who are more prosocial are happier than individuals who are more proself. This study first presents a theoretical model that mathematically describes the relationship between social preferences and subjective well-being. Then it uses survey data from the United States to empirically examine the relationship between the two. Regression analysis finds a statistically significant positive correlation between prosociality and total well-being, a correlation driven primarily by eudaimonic well-being and hedonic well-being, subdomains of total well-being. The effect size of prosociality on well-being is similar to the effect sizes of parenthood, income, and education, which are important determinants of well-being, thus confirming that prosociality is a crucial determinant of individual well-being.
HF trimer: 12D fully coupled quantum calculations of HF-stretch excited intramolecular and intermolecular vibrational states using contracted bases of intramolecular and intermolecular eigenstates
Authors: Felker Peter M. , Bačić Zlatko 
Published: June 2023

We present the computational methodology, which for the first time allows rigorous twelve-dimensional (12D) quantum calculations of the coupled intramolecular and intermolecular vibrational states of hydrogen-bonded trimers of flexible diatomic molecules. Its starting point is the approach that we introduced recently for fully coupled 9D quantum calculations of the intermolecular vibrational states of noncovalently bound trimers comprised of diatomics treated as rigid. In this paper, it is extended to include the intramolecular stretching coordinates of the three diatomic monomers. The cornerstone of our 12D methodology is the partitioning of the full vibrational Hamiltonian of the trimer into two reduced-dimension Hamiltonians, one in 9D for the intermolecular degrees of freedom (DOFs) and another in 3D for the intramolecular vibrations of the trimer, and a remainder term. These two Hamiltonians are diagonalized separately, and a fraction of their respective 9D and 3D eigenstates is included in the 12D product contracted basis for both the intra- and intermolecular DOFs, in which the matrix of the full 12D vibrational Hamiltonian of the trimer is diagonalized. This methodology is implemented in the 12D quantum calculations of the coupled intra- and intermolecular vibrational states of the hydrogen-bonded HF trimer on an ab initio calculated potential energy surface (PES). The calculations encompass the one- and two-quanta intramolecular HF-stretch excited vibrational states of the trimer and low-energy intermolecular vibrational states in the intramolecular vibrational manifolds of interest. They reveal several interesting manifestations of significant coupling between the intra- and intermolecular vibrational modes of (HF)3. The 12D calculations also show that the frequencies of the v = 1, 2 HF stretching states of the HF trimer are strongly redshifted in comparison to those of the isolated HF monomer. Moreover, the magnitudes of these trimer redshifts are much larger than that of the redshift for the stretching fundamental of the donor-HF moiety in (HF)2, most likely due to the cooperative hydrogen bonding in (HF)3. The agreement between the 12D results and the limited spectroscopic data for the HF trimer, while satisfactory, leaves room for improvement and points to the need for a more accurate PES.
Removal of toxic arsenic(iii) from an old endemic black-foot disease groundwater by oxidative electrosorption

Published: June 2023

Environmental context Naturally occurring arsenic was the likely cause of endemic black foot disease in groundwaters in Taiwan, and levels still exceed Taiwan EPA water quality standards. A method for the clean-up of these groundwaters that is both feasible and environmentally friendly is urgently needed. Oxidation of As(III) as H3AsO3 to the less toxic As(V)− and removal of As in groundwater was performed quantitatively by electrosorption using materials derived from agricultural wastes; this shows that this method has the potential to be a novel, green remediation method. Rationale Naturally occurring arsenic in the groundwater caused black-foot disease (BFD) in the 1950s on the southwest seashore of Taiwan. Recently, we found that the concentration of arsenic in groundwater taken from currently sealed wells in areas previously affected by BFD remained higher than the Taiwan (EPA) water quality standard. Although clean tap water is available in that area, removal of arsenic from the groundwater is of great importance to expand possible utilisation. Methodology Removal of arsenic from two old endemic BFD groundwaters with activated carbon (AC) electrodes recycled from agricultural wastes by electrosorption using capacitive deionisation (CDI) processes was studied. A better understanding of arsenic electrochemistry involved in electrosorption was investigated by in situ X-ray absorption near-edge structure spectroscopy. Results Arsenic removal efficiencies (61–93%) remained high across concentrations (5 and 196 mg/L). A high oxidation rate constant (0.93 h−1) for As(III)0 to As(V)− was found, allowing the electrosorption of As(V)− onto the meso- and micro-pores of the AC CDI electrodes with rate constants of 0.021 and 0.0013 h−1, respectively. Removal of arsenic from contaminated groundwater for drinking water was achieved with six CDI reactors in series. Moreover, in the presence of other ions (such as Na+, Mg2+ and Ca2+), 60–73% of As(III)0 and As(V)− ions were removed from the groundwaters by electrosorption. Discussion We have developed an engineering-feasible method for converting As(III)0 to less toxic As(V)−, enabling its removal by electrosorption, which demonstrates the feasibility for green remediation of BFD waters as well as other arsenic-contaminated groundwaters.

From bacterial quorum sensing to human language, communication is essential for social interactions. Nematodes produce and sense pheromones to communicate among individuals and respond to environmental changes. These signals are encoded by different types and mixtures of ascarosides, whose modular structures further enhance the diversity of this nematode pheromone language. Interspecific and intraspecific differences in this ascaroside pheromone language have been described previously, but the genetic basis and molecular mechanisms underlying the variation remain largely unknown. Here, we analyzed natural variation in the production of 44 ascarosides across 95 wild
Caenorhabditis elegans
strains using high-performance liquid chromatography coupled to high-resolution mass spectrometry. We discovered wild strains defective in the production of specific subsets of ascarosides (
e.g.
, the aggregation pheromone icas#9) or short- and medium-chain ascarosides, as well as inversely correlated patterns between the production of two major classes of ascarosides. We investigated genetic variants that are significantly associated with the natural differences in the composition of the pheromone bouquet, including rare genetic variants in key enzymes participating in ascaroside biosynthesis, such as the peroxisomal 3-ketoacyl-CoA thiolase,
daf-22
, and the carboxylesterase
cest-3
. Genome-wide association mappings revealed genomic loci harboring common variants that affect ascaroside profiles. Our study yields a valuable dataset for investigating the genetic mechanisms underlying the evolution of chemical communication.
Annotation uncertainty in the context of grammatical change

Published: June 2023

AbstractThis paper elaborates on the notion of uncertainty in the context of annotation in large text corpora, specifically focusing on (but not limited to) historical languages. Such uncertainty might be due to inherent properties of the language, for example, linguistic ambiguity and overlapping categories of linguistic description, but could also be caused by a lack of annotation expertise. By examining annotation uncertainty in more detail, we identify the sources, deepen our understanding of the nature and different types of uncertainty encountered in daily annotation practice, and discuss practical implications of our theoretical findings. This paper can be seen as an attempt to reconcile the perspectives of the main scientific disciplines involved in corpus projects, linguistics and computer science, to develop a unified view and to highlight the potential synergies between these disciplines.

Published: June 2023

Abstract

Soybean,
Glycine
max (Fabaceae), is considered one of the world’s most important crops. Planted on millions of hectares worldwide, the management of soybean pests usually requires large amounts of chemicals. Currently, integrated pest management (IPM) is one way to protect crops through the integration of different pest control tools based on plant tolerance, adoption of economic thresholds (ETs), scouting procedures, use of selective insecticides, biological control, and other sustainable pest management tools, which helps to maintain environmental quality in an ecological and economical manner. This soybean-IPM case study in Brazil is an example of how it is possible to manage soybean fields sustainably, preserving or even increasing productivity and reducing production costs, consequently, maximizing profits. In this case, we discuss the advantages and benefits as well as possible challenges for soybean-IPM adoption. We provide examples of how to reinforce the importance of IPM by focusing on experiences from Brazil, one of the major soybean producers and exporters in the world. We analyse IPM case studies to illustrate the importance for farmers to have easy and fast access to information on medium- and long-term benefits of IPM. Overall, this case highlights both the successful achievements of the Parana State in Brazil and how important IPM is for soybean sustainability.

Change of electrostatic field polarity in the melt-blown polypropylene electret fabrics with corona charging
Authors: Zhang Jianfeng , Chen Gangjin , Gao Xiaoli 
Published: June 2023

Abstract
Corona-charged melt-blown polypropylene (MBPP) electret fabrics are promising candidates for air filtration, wearable sensing and energy harvesting applications. However, the underlying corona charging mechanism still needs further exploration to enhance the charge storage performance of electret fabrics. Herein, the phenomenon of surface electrostatic field polarity change in corona-charged MBPP electret fabrics is reported. By using negative corona charging and altering charging conditions such as sample size, charging time, charging voltage, discharge electrode shape and ground electrode contacting sample mode, three electrostatic field distribution modes can be formed on the two sides of samples, including (i) both front and back sides are negative; (ii) the front side is negative, and the back is positive; (iii) the front side is positive, and the back is negative. A corona charging mechanism based on plasma sheath is proposed as an explanation. The origin location and thickness of plasma sheath, which are affected by charging conditions, determine the electrostatic field polarity of MBPP fabrics. MBPP electrets with different electrostatic field polarities do not differ substantially in charge storage stability.

Published: June 2023

Abstract
The visualization of electronic products is essential for the digitization and visualization of human-computer exchange in the future smart world. However, due to its large non-translucent aperture, the conventional hologram metasurface urgently needs transparency for wide scene usage. In this paper, an optically transparent holographic impedance metasurface with a low profile is investigated for generating orbital angular momentum (OAM) vortex waves in the radio-frequency domain for the first time. Indium tin oxide is applied to perform the metal functionality, which is featured by high optical transparency, and polymethyl methacrylate is proposed as the substrate material in the meta-atom design. By virtue of classic optical metasurface theory and leaky-wave principle, holographic impedance mapping is achieved, so the surface wave generated by the monopole port is effectively converted into a radiating vortex wave at 15 GHz. The prototype has been manufactured and fabricated, and the experiment results exhibit good agreements with theory and simulation analyses, showing a good prospect for OAM vortex wave launch in visualized applications.
Pion-mediated Cooper pairing of neutrons: beyond the bare vertex approximation
Authors: Zhu Hao-Fu , Liu Guo-Zhu 
Published: June 2023

Abstract
In some quantum many particle systems, the fermions could form Cooper pairs by exchanging intermediate bosons. This then drives a superconducting phase transition or a superfluid transition. Such transitions should be theoretically investigated by using proper non-perturbative methods. Here we take the neutron superfluid transition as an example and study the Cooper pairing of neutrons mediated by neutral π-mesons in the low-density region of a neutron matter. We perform a non-perturbative analysis of the neutron–meson coupling and compute the pairing gap Δ, the critical density ρ

c
, and the critical temperature T

c
by solving the Dyson–Schwinger equation of the neutron propagator. We first carry out calculations under the widely used bare vertex approximation and then incorporate the contribution of the lowest-order vertex correction. This vertex correction is not negligible even at low densities and its importance is further enhanced as the density increases. The transition critical line on density-temperature plane obtained under the bare vertex approximation is substantially changed after including the vertex correction. These results indicate that the vertex corrections play a significant role and need to be seriously taken into account.

Published: June 2023

Abstract
To ensure the nanometer-level running accuracy of the ultra-precision spindle, the radial error motion should be precisely measured. However, the asynchronous errors induced by the measurement instrument will mix in the measured data and significantly deteriorate the measurement precision. In this study, a novel adaptive digital filter method (ADFM) is proposed to suppress the asynchronous errors and lower requirements for the precision of measurement instruments based on the Donaldson reversal method. Specifically, the Gaussian mixture model is first used to investigate the characteristics of asynchronous errors and obtain appropriate initial filter parameters. The least mean square algorithm is utilized to adaptively optimize the filter parameters. Monte Carlo simulation results indicate that ADFM can suppress asynchronous errors by more than 90% compared with the traditional methods. Experimental results show that the standard deviation uncertainty is reduced by more than 60%. Besides, the measurement results of two sensors with different precision verify the feasibility of ADFM.
