Published: November 2022

Objective Preterm birth (PTB, birth before 37 gestational weeks) is the leading cause of neonatal death and a major challenge for obstetric and neonatal care. About two-thirds of PTBs are spontaneous PTB (sPTB), of which approximately 30% start with preterm premature rupture of membranes (PPROM). The aim of the study was to investigate risk factors and maternal and perinatal outcomes in sPTB with and without PPROM.
Study Design This is a national population-based cohort study including all singleton pregnancies in nulliparous women with spontaneous onset of labor and vaginal births (n = 266,968) registered in the Swedish Medical Birth Register 2005 to 2014. sPTB with PPROM (sPTB-PPROM) and sPTB without PPROM were compared regarding risk factors and maternal and perinatal outcomes. Logistic regression was used to estimate adjusted odds ratios (aORs) with 95% confidence intervals (CIs). Adjustments were made for maternal age, body mass index, country of birth, smoking, chronic hypertension, pregestational and gestational diabetes, and gestational length.
Results sPTB-PPROM (n = 5,037), compared with sPTB without PPROM (n = 8,426), was more common in women with previous spontaneous abortions, prepregnancy urinary tract infections, chronic hypertension, and gestational diabetes and had a higher risk of postpartum endometritis (aOR: 2.78, 95% CI: 1.55–5.00). Infants born to women with sPTB-PPROM had a lower risk of birth asphyxia (aOR: 0.60, 95% CI: 0.43–0.83), respiratory distress syndrome (aOR: 0.86, 95% CI: 0.70–1.00), retinopathy of prematurity (aOR: 0.93, 95% CI: 0.92–0.94), necrotizing enterocolitis (aOR: 0.95, 95% CI: 0.94–0.96), and higher risk of hypoglycemia (aOR: 1.14, 95% CI: 1.01–1.28), and hyperbilirubinemia (aOR: 1.28, 95% CI: 1.19–1.38) compared with infants born to sPTB without PPROM.
Conclusion Our findings of risk factors and distinct differences in adverse outcomes after sPTB-PPROM compared with sPTB without PPROM are of vital importance and might serve as a basis when elaborating programs for the prevention and management of PPROM.

Published: November 2022

Objective Anemia of pregnancy is a common condition associated with adverse obstetric outcomes. However, little is known about its long-term effect on the offspring. This study aimed to evaluate a possible association between anemia during pregnancy and the long-term incidence of infectious morbidity in the offspring.
Study Design A large population-based retrospective study was conducted at the Soroka University Medical Center, the sole tertiary medical center in the south of Israel. The study included deliveries between the years 1991 and 2014 and compared long-term infectious morbidity of offspring of women with and without anemia during pregnancy (defined as hemoglobin level below 11 g/dL). The long-term incremental incidence of hospitalizations of offspring up to 18 years of age due to infectious morbidity was evaluated using Kaplan–Meier survival curves, while Cox's regression model was used to control for confounders.
Results During the study period, 214,244 deliveries met the inclusion criteria, of which 110,775 (51.7%) newborns were born to mothers with anemia during pregnancy. The overall infectious-related hospitalization rate was significantly higher in children from the exposed group (odds ratio [OR] = 1.07, 95% confidence interval [CI]: 1.04–1.10, p < 0.01). Kaplan–Meier survival curves showed a significantly higher cumulative incidence of hospitalizations due to infectious diseases as compared with children in the unexposed group (log-rank test, p < 0.01). The Cox model demonstrated a significant and independent association between maternal anemia and the long-term risk for hospitalization due to infectious diseases of the offspring (adjusted hazard ratio [aHR]: 1.09, 95% CI: 1.06–1.12, p < 0.01).
Conclusion Offspring of anemic mothers are at a greater risk for infectious-related hospitalizations in their first 18 years of life.

Published: November 2022

Objective This study aimed to evaluate the association of induction method on delivery mode in pregnancies complicated by oligohydramnios with and without fetal growth restriction (FGR).
Study Design This was a secondary analysis of a National Institutes of Health funded retrospective cohort study of singleton deliveries at a tertiary-care hospital between 2002 and 2013 with diabetes, mild hypertension, and/or FGR. Chart abstraction was performed by trained research nurses. Patients with a diagnosis of fetal oligohydramnios with and without FGR were identified. Our analytic cohort was further stratified into three groups per initial induction agent: prostaglandins (PGEs) alone, PGE plus mechanical ripening, or oxytocin only. Primary outcome was mode of delivery. Secondary outcomes included indications for cesarean delivery and neonatal morbidity.
Results Out of 4,929 patients in the original database, 546 subjects with fetal oligohydramnios were identified; of these, 270 were induced and included for analysis. Outcomes were compared between 171 patients who had fetuses with isolated oligohydramnios and 99 patients who had fetuses with oligohydramnios and FGR. There were no significant differences in demographic characteristics between the groups. Patients with fetuses with isolated oligohydramnios had similar rates of spontaneous vaginal delivery (SVD) when PGEs were used (n = 44/79, 55.7% PGE alone, n = 44/76, 57.9% PGE with mechanical ripening) and when they were not used (n = 5/13, 38.5% oxytocin alone; p = 0.43). Similarly, the majority of patients in both cohorts underwent SVD regardless of induction method (n = 30/44, 68.2% PGE alone, n = 30/44, 68.2% PGE with mechanical ripening, and n = 6/10, 60% oxytocin alone; p = 0.90). There was no significant difference in composite neonatal morbidity.
Conclusion In patients with fetuses with oligohydramnios with and without FGR, most patients delivered by SVD regardless of induction method. In this population, PGE use was associated with a high chance of SVD in patients with fetuses with suspected placental insufficiency regardless of the presence of absence of FGR.

Authors: Vazquez-Martel Clara , Mainik Philipp , Blasco Eva 
Published: November 2022

Photoinitiating systems (PISs) are key components in photocurable formulations (inks) for three-dimensional (3D) printing. Natural PISs are promising and more environmentally friendly alternatives to conventional photoinitiators. These systems offer enhanced features such as less toxicity and therefore, higher biocompatibility. Furthermore, they can be found in a large “color palette” variety (absorbing in the different regions of the UV-visible spectrum) enabling new possibilities in the field of 3D printing. In this review, we outline the current efforts to implement natural and naturally derived PISs in light-based 3D printing. First, recently applied natural PISs and their performance for light-based 3D printing are discussed. In a second part, an overview of naturally derived PISs including the most common synthetic strategies are provided. Last, current challenges as well as future perspectives of the field are discussed.IntroductionNatural Photoinitiating SystemsNaturally Derived Photoinitiating SystemsConclusions and Outlook

Abstract
Background Multiple sclerosis (MS) has a negative effect on employment status.
Objective To present the preliminary results of a special questionnaire designed to collect employment information on patients with MS.
Methods The questionnaire on the impact of MS on employment status was completed by 63 patients. Fatigue, cognition, and depression were also evaluated, and 33 healthy participants were recruited as a control group.
Results Regarding the patients' employment status, we found rates of 31.7% of full-time employment, 28.6% of part-time employment, 7.9% of unemployment due to MS, 4.8% of housewives, 1.6% retirement due to age, 15.9% of retirement due to disability, 7.9% of medical leave due to MS, and 1.6% of medical leave for other reasons. The rate of unemployment among the patients was significantly higher compared with that of the control group. Out of 38 working patients, 31% had been absent from work for the previous 3 months due to MS, and 50% had to make changes in their work to remain employed. Out of the 19 unemployed patients, 78% said that walking difficulties were the cause of unemployment, while 52% thought cognitive impairment was the cause.
Conclusions The questionnaire provides a record of the employment status of patients with MS and describes the impact on work from their point of view.

Abstract
Objective Dentists in Indonesia as health workers have a role to play in improving the quality of life of others; thus, dentists' participation in growth stunting prevention is essential. It is also supported by the fact that growth stunting correlates with dental and oral health. Therefore, a dentist's knowledge and perception of growth stunting and its prevention affect the success of a dentist's role in the community.This study aimed to explore the knowledge and perceptions of growth stunting and its prevention in dentists in Bandung.
Materials and Methods A descriptive study was conducted on general dental practitioners and dental specialists in Bandung. The number of participants gathered were 76 general dental practitioners and 30 dental specialists, which, if added all together, are 106 dentists as the study participants. Data was collected using a knowledge-based questionnaire containing three dimensions: knowledge about nutrition, growth and development, and health behavior. In addition, a perception questionnaire contains statements categorized into four dimensions: awareness, adoption, implementation, and maintenance. The questionnaire was distributed online using Google Form. A descriptive analysis was then done on the collected data.
Results Analysis of the findings showed that 80.19% of the participants have good knowledge of growth stunting and its prevention, 16.98% moderate, and 2.83% have poor knowledge. As for the perception category, the number of participants with positive perceptions is 53.77%, while the number of participants with negative perceptions is 46.23%.
Conclusion Most dentists in the city of Bandung have an excellent knowledge of growth stunting and its prevention and positively perceive growth stunting and its prevention.

Authors: Ninenko S. I. , Brazhkin V. V. 
Published: November 2022

A setup with a working volume of more than 10 mm3 has been fabricated to experimentally study the optical properties of gases, liquids, and solutions in a wide range of temperature (from 200 to 500 K) at hydrostatic pressures up to 1 GPa. The experimental parameters can be maintained with an accuracy of 0.1 K and 1.5 MPa for up to 3–4 h. To introduce laser radiation and to record spectra, high-temperature optical fibers of increased strength in a metal sheath are introduced directly into the working chamber. The primary goal of experiments is to study the Raman radiation at vibron frequencies in supercritical fluids of molecular substances (N2, CO2, CH4, etc.).

Published: November 2022

We demonstrate a method to efficiently load a pair of 40Ca+–27Al+ ion crystals with sympathetic cooling and pulsed laser ablation, serving as a starting step for the 27Al+ clock. We achieved a technique to rapidly detect the loading of hot ions by monitoring the 2S1/2 → 2D5/2 narrow transition of 40Ca+ that couples to the shared motional modes between the two ions. The sympathetic cooling time of the 40Ca+–27Al+ ion pair is measured. Two traps are employed to compare the loading time from two directions and it was found that the loading from the axial direction takes much shorter time than loading from the radial direction of the trap. With the help of adaptively controlled trap potential, our method reduced the average loading time of a 40Ca+–27Al+ pair from 26 to 1 min. This research is an important step for increasing the uptime ratio of the 27Al+ optical clock and is useful for other mixed-species ion crystals based on sympathetic cooling.
Regimenting Circulation: A Case Study of Mediatization in Corporate Communication
Authors: Koh Kyung-Nan 
Published: November 2022

AbstractCommunication is necessary work and imagined want in corporations. Using firsthand data from a midsize corporation, this essay discusses the professional practices of corporate communication as a metadiscursive project of proleptically shaping the circulation of representations of the corporation. In corporate work, activities spoken of as “communication” are segmented and ritualized with respect to who the corporation seeks to engage in discursive and semiotic frameworks of participation and which communicative media it employs. The ways in which various communicative scenarios are imagined and framed in the design and use of corporate media are examined, as is the manner in which the boundary of the corporation’s communicative activity is drawn and (re)defined through metapragmatic regimentations of future participatory encounters. The expertise of corporate communication practitioners involves the ability to formulate the corporation as the mediatized center of the groups with which it communicates and to devise messages that target diverse groups as addressees.
On the uniqueness of supersymmetric AdS(5) black holes with toric symmetry
Authors: Lucietti James , Ntokos Praxitelis , Ovchinnikov Sergei G 
Published: November 2022

Abstract
We consider the classification of supersymmetric AdS5 black hole solutions to minimal gauged supergravity that admit a torus symmetry. This problem reduces to finding a class of toric Kähler metrics on the base space, which in symplectic coordinates are determined by a symplectic potential. We derive the general form of the symplectic potential near any component of the horizon or axis of symmetry, which determines its singular part for any black hole solution in this class, including possible new solutions such as black lenses and multi-black holes. We find that the most general known black hole solution in this context, found by Chong, Cvetic, Lü and Pope (CCLP), is described by a remarkably simple symplectic potential. We prove that any supersymmetric and toric solution that is timelike outside a smooth horizon, with a Kähler base metric of Calabi type, must be the CCLP black hole solution or its near-horizon geometry.
TCFHs, hidden symmetries and M-theory backgrounds
Authors: Papadopoulos G , Pérez-Bolaños E 
Published: November 2022

AbstractWe present the twisted covariant form hierarchy (TCFH) of 11-dimensional supergravity and so demonstrate that the form bilinears of supersymmetric solutions satisfy a generalisation of the conformal Killing-Yano equation with resepct to the TCFH connection. We also compute the Killing-Stäckel, KY and closed conformal Killing-Yano tensors of all spherically symmetric M-branes that include the M2-brane, M5-brane, KK-monopole and pp-wave and demonstrate that their geodesic flows are completely integrable by giving all independent conserved charges in involution. We then find that all form bilinears of pp-wave and KK-monopole solutions generate (hidden) symmetries for spinning particle probes propagating on these backgrounds. Moreover, there are Killing spinors such that some of the 1-, 2- and 3-form bilinears of the M2-brane solution generate symmetries for spinning particle probes. We also explore the question on whether the form bilinears are sufficient to prove the integrability of particle probe dynamics on 11-dimensional supersymmetric backgrounds.
Multi-dimensional particle filter-based estimation of phase line biases for single-differenced ambiguity resolution in GNSS-based attitude determination
Authors: Wu Mingkui , He Yan , Wu Hao , Liu Wanke 
Published: November 2022

Abstract
Global navigation satellite systems (GNSSs) have been widely used to provide real-time and high-precision attitude information for land vehicles, ships and aircraft over the past few decades. With the joint use of emerging multi-GNSS common-clock receivers and the single-differenced (SD) model, the accuracy of pitch and roll can be significantly improved to the same level as that of yaw. However, the prerequisite is that the frequency-dependent phase line biases (LBs) in multiple GNSS systems and frequencies are accurately and rapidly estimated. In this contribution, we intend to solve this problem by using a multi-dimensional particle filter (PF)-based approach. We first investigate the relationship between the ratio value and the multi-dimensional phase LBs. Results have revealed that the ratio value can be used to judge the quality of multi-dimensional phase LBs and represent the likelihood function of the observations. We then present the procedure of multi-dimensional PF-based phase LBs estimation for SD ambiguity resolution and attitude determination. An improved strategy is also proposed to reduce the computation time. Finally, we take the two-dimensional case as a representative example to evaluate the performance of the proposed method in aspects of the convergence and accuracy of phase LB estimates, the attitude determination accuracy, and the computation time. Experimental results from two static datasets have demonstrated that the two-dimensional phase LBs basically rapid converge within 20 epochs. Moreover, compared with the double-differenced method, the proposed multi-dimensional PF-based SD method could provide comparable yaw accuracy and much better pitch accuracy. The pitch accuracy is improved to the same level as yaw by approximately 42.9%–50.0%. With regard to the computation time, it is found that with the proposed modification strategy, the single-epoch computation times are significantly reduced by approximately 90.7%–93.5%, and they are mostly within 0.05 s for most of the epochs on a personal computer.

Abstract
The visual simultaneous localization and mapping (SLAM) system is prone to tracking failure in complex and variable environments and lighting change environments. Therefore, an adaptive S-piecewise from an accelerated segment test (FAST) and boosted efficient binary local image descriptor or BEBLID (ASFB) feature extraction algorithm is proposed to obtain better matching results and more accurate poses. The algorithm designs a segment function adaptive thresholding FAST feature extraction algorithm based on the sigmoid function trajectory. It also calculates different thresholds for each pixel point in the image to complete the feature extraction, which adaptively calculates the threshold value for different luminance environments, to improve the quality of feature points, and uses BEBLID instead of binary robust independent elementary feature (BRIEF) to complete the description of feature points, which improves the accuracy of description information. The experiment selects KITTI and Euroc datasets, and the results show that the ASFB feature extraction algorithm performs better than the oriented FAST and rotated BRIEF algorithm in both the illumination changing environment and the normal environment. In addition, the bit pose accuracy is also improved. Moreover, it can meet the operational efficiency requirements of the SLAM algorithm.
Failure of the geometric approach prediction of excess work scaling for open and isolated quantum systems
Authors: Soriani Artur , Miranda Eduardo , Bonança Marcus V S 
Published: November 2022

Abstract
The task of finding optimal protocols that minimize the energetic cost of thermodynamic processes of long yet finite duration τ is a pressing one. We approach this problem here in a rigorous and systematic fashion by means of the adiabatic perturbation theory of closed Hamiltonian quantum systems. Our main finding is a 1/τ
2 scaling of the excess work for large τ in gapped systems. This result is at odds with the asymptotic 1/τ prediction of the geometric approach to optimization, which is predicated on the slow evolution of open systems close to canonical equilibrium. In contrast, our approach does not lead to an obvious geometric interpretation. Furthermore, as the thermodynamic work does not depend on how an isolated quantum system is split into a system of interest and its environment, our results imply the failure of the geometric approach prediction even for open systems. Additionally, we provide alternative optimization procedures, both for slowly-varying processes described by adiabatic perturbation theory and for weakly-varying processes described by linear response theory. Our findings are benchmarked and confirmed through the application to the driven transverse-field Ising chain.
