Finite‐time local piecewise control for parabolic PDEs with ODE output feedback
Authors: Li Manna , Mao Weijie 
Published: November 2021

AbstractThis paper is devoted to the finite‐time local piecewise control for parabolic partial differential equations (PDEs) by using dynamic output feedback control strategy, where the controller is designed as an ordinary differential equation (ODE). This makes the closed‐loop system PDE‐ODE coupled, which is employed to accurately describe the dynamics of the PDE system. According to the constructed PDE‐ODE coupled model, a local piecewise dynamic feedback control law is first proposed. Sufficient conditions on finite‐time stabilisation of the parabolic PDE‐ODE coupled system by the suggested feedback controller are then developed in the sense of both complete spatial measurement and incomplete spatial measurement of the observed output of the PDE system, respectively. Finally, the issues regarding the finite‐time stabilisation of the closed‐loop system is converted into the feasibility of matrix inequalities, and some simulation studies are provided to verify the effectiveness of the proposed results.

Published: November 2021

Context. Different relationships between the Hα and Ca II chromospheric emissions have been reported in solar-type stars. In particular, the time-series of emissions in these two lines are clearly anti-correlated for a few percent of the stars, contrary to what is observed on the Sun.
Aims. Our objective is to characterise these relationships in more detail using complementary criteria, and to constrain the properties of filaments and plages that are necessary to explain the observations.
Methods. We analysed the average level and variability of the Hα and Ca II emission for 441 F-G-K stars, paying particular attention to their (anti-)correlations on both short and long timescales. We also computed synthetic Hα and Ca II time-series for different assumptions of plage and filament properties and compared them with the observations.
Results. We were not able to find plage properties that, alone, are sufficient to reproduce the observations at all timescales simultaneously, even when allowing different Hα and Ca II emission relationships for different stars. We also specified the complex and surprising relationship between the average activity levels of both indexes, in particular for low-activity stars.
Conclusions. We conclude that plages alone are unlikely to explain the observed variety of relationships between Ca II and Hα emission, and that the presence of other phenomena like filaments may help to reconcile the models with observations.

Aims. We report the detection of long-period radial velocity (RV) variations in three giant stars, HD 19615, HD 150010, and HD 174205, using precise RV measurements.
Methods. These detections are part of the Search for Exoplanets around Northern Circumpolar Stars (SENS) survey being conducted at the Bohyunsan Optical Astronomy Observatory (BOAO). The nature of the RV variations was investigated by analyzing the photometric and line shape variations. We found no variability with the RV period in these quantities and conclude that the RV variations are most likely caused by planetary companions.
Results. Orbital solutions for the three stars yield orbital periods of 402 d, 562 d, and 582 d and minimum masses of 8.5 MJ, 2.4 MJ, and 4.2 MJ, respectively. These masses and periods are typical for planets around intermediate-mass stars, although some unclear interpretations and recent studies may being calling some planet convictions into question. Nevertheless, the SENS program is contributing to our knowledge of giant planets around intermediate-mass stars.

Aims. The light curve of the microlensing event KMT-2021-BLG-0912 exhibits a very short anomaly relative to a single-lens single-source form. We investigate the light curve for the purpose of identifying the origin of the anomaly.
Methods. We model the light curve under various interpretations. From this, we find four solutions, in which three solutions are found underthe assumption that the lens is composed of two masses (2L1S models), and the other solution is found under the assumption that the source is comprised of binary stars (1L2S model). The 1L2S model is ruled out based on the contradiction that the faint source companion is bigger than its primary, and one of the 2L1S solutions is excluded from the combination of the poorer fit, blending constraint, and lower overall probability, leaving two surviving solutions with the planet/host mass ratios of q ~ 2.8 × 10−5 and ~ 1.1 × 10−5. A subtle central deviation supports the possibility of a tertiary lens component, either a binary companion to the host with a very large or small separation, or a second planet lying near the Einstein ring, but it is difficult to claim a secure detection due to the marginal improvement of the fit, lack of consistency among different data sets, and difficulty in uniquely specifying the nature of the tertiary component.
Results. With the observables of the event, it is estimated that the masses of the planet and host are ~ (6.9 M⊕, 0.75 M⊙) according to one solution and~(2.8 M⊕, 0.80 M⊙) according to the other, indicating that the planet is a super Earth around a K-type star, regardless of the solution. The fact that 16 (including the one reported in this work) out of 19 microlensing planets with M ≲ 10 M⊕ were detected during the last 6 yr nicely demonstrates the importance of high-cadence global surveys in detecting very low-mass planets.

Abstract
Purpose This study compared the functional and radiological outcomes and complications of single- (SS) and two-stage (TS) bilateral high tibial osteotomy (HTO).
Methods From 2014 to 2018, 48 patients underwent bilateral HTO surgery for osteoarthritis. The outcomes of SS in 28 knees and TS in 32 knees were compared using the Knee Injury and
Osteoarthritis Outcome Score (KOOS) and Oxford Knee Score (OKS) as functional outcomes, and the medial proximal tibial (MPTA), hip-knee-ankle (HKA), tibial slope (TSA) angles, and mechanical
axis deviation (MAD) as radiological outcomes. We also evaluated the estimated blood loss (EBL).
Results No significant differences in the pre- and postoperative mean OKS and KOOS were found between the groups. There was a significant difference between the groups in the last
postoperative HKA angle (− 0.9 ± 3.9 and 1.8 ± 4.3°, respectively). In SS and TS, the respective total mean surgical time was 108 ± 28 and 143 ± 36 min (p < 0.001). The mean calculated
EBL was 612 ± 267 and 544 ± 357 mL, respectively, (p = 0.5), and the mean length of stay (LOS) was 2.2 ± 0.83 and 3.5 ± 1.0 days, respectively, (p = 0.01).
Conclusion SS bilateral HTO is a safe reasonable option for certain patients with bilateral knee osteoarthritis because it involves a single hospitalization, one-time exposure to
anesthesia risks, accelerated rehabilitation, earlier return to expected life status, reduced total hospital stay, and a likely decrease in total cost.
Die erste niedergelassene Praxis für nierenkranke Kinder und Jugendliche in Deutschland
Authors: Kolzem Tanja 
Published: November 2021

ZUSAMMENFASSUNGIn Deutschland sind rund 1000 Kinder und Jugendliche von einer chronischen Nierenerkrankung betroffen. Nierenkranke Kinder benötigen eine besondere Versorgung. Neben der Behandlung durch Kindernephrologen ist eine multiprofessionelle Mitbetreuung durch weitere Fachabteilungen erforderlich. Während erwachsene nierenkranke Patienten überwiegend durch niedergelassene Nephrologen behandelt werden, war dieses für Kinder bislang nur in Universitätskinderkliniken oder größeren Kinderkrankenhäusern möglich. Im Frühjahr 2020 wurde die erste niedergelassene Praxis für nierenkranke Kinder und Jugendliche in Bonn eröffnet.

HÄ und deren Perspektiven auf digitale Lösungen.
Methodik Eine fragebogenbasierte Querschnittstudie unter 600
zufällig ausgewählten HÄ in Sachsen-Anhalt.
Ergebnisse Die Antwortquote war 20% (n=114). Das mittlere
Alter der teilnehmenden HÄ lag bei 53 Jahren, zwei Drittel waren Frauen
(65%). HÄ nutzen hauptsächlich Fax (92%) oder
Telefon (87%) zur Kommunikation mit Pflegeheimen. Digitale

arbeiten. 33% der HÄ haben vollständig digitale
Patientenakten. Nur 9% arbeiten ausschließlich auf
Papierbasis.
Schlussfolgerung Obwohl HÄ eine Offenheit für
digitalisierte Kommunikation mit Pflegeheimen zeigen, werden fast
ausschließlich Fax und Telefon genutzt. HÄ bevorzugen es,
weniger komplexe Aufgaben, wie Medikationsplanänderung und
Überweisungen, digital zu bearbeiten. Wenige HÄ können
es sich vorstellen, komplexere Prozeduren wie die Versorgung akuter
Gesundheitsprobleme und Kurvenvisiten digital abzuwickeln. Nur 8%

Published: November 2021

Abstract
Objective To investigate whether patients with a previous recombinant follicle stimulating hormone (rFSH)-stimulated cycle would have improved outcomes with rFSH + recombinant luteinizing hormone (rLH) stimulation in the following cycle.
Methods For the present retrospective case-control study, 228 cycles performed in 114 patients undergoing intracytoplasmic sperm injection (ICSI) between 2015 and 2018 in an in vitro fertilization (IVF) center were evaluated. Controlled ovarian stimulation (COS) was achieved with rFSH (Gonal-f, Serono, Geneva, Switzerland) in the first ICSI cycle (rFSH group), and with rFSH and rLH (Pergoveris, Merck Serono S.p.A, Bari, Italy) in the second cycle (rFSH + rLH group). The ICSI outcomes were compared among the groups.
Results Higher estradiol levels, oocyte yield, day-3 high-quality embryos rate and implantation rate, and a lower miscarriage rate were observed in the rFSH + rLH group compared with the rFSH group. In patients < 35 years old, the implantation rate was higher in the rFSH + rLH group compared with the rFSH group. In patients ≥ 35 years old, higher estradiol levels, oocyte yield, day-3 high-quality embryos rate, and implantation rate were observed in the rFSH + rLH group. In patients with ≤ 4 retrieved oocytes, oocyte yield, mature oocytes rate, normal cleavage speed, implantation rate, and miscarriage rate were improved in the rFSH + rLH group. In patients with ≥ 5 retrieved oocytes, higher estradiol levels, oocyte yield, and implantation rate were observed in the rFSH + rLH group.
Conclusion Ovarian stimulation with luteinizing hormone (LH) supplementation results in higher implantation rates, independent of maternal age and response to COS when compared with previous cycles stimulated with rFSH only. Improvements were also observed for ICSI outcomes and miscarriage after stratification by age and retrieved oocytes.

Published: November 2021

AbstractMalalignment of total knee arthroplasty (TKA) components affects function and survivorship. Common practice is to set coronal alignment prior to adjusting slope. With improper jig placement, adjustment of the slope may alter coronal alignment. The purpose of this study was to quantify the change in coronal alignment with increasing posterior tibial slope while comparing two methods of jig fixation. A prospective consecutive series of 100 patients underwent TKA using computer navigation. Fifty patients had the extramedullary cutting jig secured proximally with one pin and 50 patients had the jig secured proximally with two pins. Coronal alignment (CA) was recorded with each increasing degree of posterior slope (PS) from 0 to 7 degrees. Mean CA and change in CA were compared between cohorts. Utilizing one pin, osteotomies drifted into varus with an average change in CA of 0.34 degrees per degree PS. At 4 degrees PS, patients started to have >3 degrees of varus with 12.0% having >3 degrees of varus at 7 degrees PS. Utilizing two pins, osteotomies drifted into valgus with an average change of 0.04 degrees in CA per degree PS. No patients in the two-pin cohort fell outside 3 degrees varus/valgus CA. CA was significantly different at all degrees of PS between the cohorts. Changes in PS influenced CA making verification of tibial cut intraoperative critical. Use of >1 pin and computer navigation were beneficial to prevent coronal plane malalignment. This relationship may explain why computer navigation has been shown to improve alignment as well as survivorship and outcomes in some patients, especially those <65 years.

Published: November 2021

Objective The aim of the study is to evaluate whether values and the shape of the glucose curve during the oral glucose tolerance test (OGTT) in pregnancy identify women at risk of developing hypertension (HTN) later in life.
Study Design This category includes the secondary analysis of a follow-up from a mild gestational diabetes mellitus (GDM) study that included a treatment trial for mild GDM (n = 458) and an observational cohort of participants with abnormal 1-hour glucose loading test only (normal OGTT, n = 430). Participants were assessed at a median of 7 (IQR 6–8) years after their index pregnancy, and trained staff measured their blood pressure (systolic blood pressure [SBP]; diastolic blood pressure [DBP]). The association between values and the shape of the glucose curve during OGTT in the index pregnancy and the primary outcome defined as elevated BP (SBP ≥120, DBP ≥80 mm Hg, or receiving anti-HTN medications), and secondary outcome defined as stage 1 or higher (SBP ≥130, DBP ≥80 mm Hg, or receiving anti-HTN medications) at follow-up were evaluated using multivariable regression, adjusting for maternal age, body mass index, and pregnancy-associated hypertension during the index pregnancy.
Results There was no association between fasting, 1-hour OGTT, and the outcomes. However, the 2-hour OGTT value was positively associated (adjusted odds ratio [aRR] per 10-unit increase 1.04, 95% CI 1.01–1.08), and the 3-hour was inversely associated (aRR per 10-unit increase 0.96, 95% CI 0.93–0.99) with the primary outcome. When the shape of the OGTT curve was evaluated, a monophasic OGTT response (peak at 1 hour followed by a decline in glucose) was associated with increased risk of elevated BP (41.3vs. 23.5%, aRR 1.66, 95% CI 1.17–2.35) and stage 1 HTN or higher (28.5 vs. 14.7%, aRR 1.83, 95% CI 1.15–2.92), compared with a biphasic OGTT response.
Conclusion Among persons with mild GDM or lesser degrees of glucose intolerance, the shape of the OGTT curve during pregnancy may help identify women who are at risk of HTN later in life, with biphasic shape to be associated with lower risk.

Published: November 2021

Background The ‘Down to Test (DTT)’ campaign is a sexually transmissible infection (STI) social marketing intervention delivered through outdoor music festival activations and supported by digital media communications in New South Wales, Australia. This paper investigates whether and how the tailored messages reached the intended audience. Methods Data was collected through three annual rounds of online surveys post campaign exposure, targeting young people (aged 15–29 years) attending 14 music festivals in NSW from October 2017 to March 2020. Descriptive statistics, principal component analysis and multivariable logic regression were applied to identify the key client segment and factors associated with a strong intention for future STI screening. Results Of the 10 044 participants with a valid urine specimen submitted, 261 (2.8%) tested positive for chlamydia. Altogether, 1776 participants (median age = 22) self-completed the evaluation surveys online with more being female (73.4%) than male (26.2%). Participants were mostly Australian-born (89.5%), heterosexual (82.6%) and the majority being sexually active (96.7%). Rates of self-reported lifetime STI testing (70.4%) and intention for future STI screening (‘definitely yes’ in the next 12 months, 39.0%) were also high. The most significant factor associated with future intention for STI testing is the Sexual Experience and Perception Factor (adjusted odds ratio [AOR] = 2.02; 95%CI 1.76–2.32; P < 0.001), followed by the Sexual Beliefs and Attitudes Factor (AOR = 1.14; 95% CI 1.01–1.30; P < 0.05). Conclusions The NSW state-wide DTT campaign has largely reached sexually active youth who are attentive to sexual health promotion messages and contributed to enhanced STI screening in a fun and peer-supportive environment.
Heme auxotrophy in abundant aquatic microbial lineages
Authors: Kim Suhyun , Kang Ilnam , Lee Jin-Won , Jeon Che Ok , Giovannoni Stephen J. , Cho Jang-Cheon 
Published: November 2021

SignificanceHeme is essential for respiration. As a cofactor of cytochromes, heme functions as a main electron carrier in all respiratory electron transport chains. Therefore, it is natural to expect all respiring and free-living microorganisms to make heme. Against this expectation, here we show that the acI lineage, one of the most abundant bacterial groups in freshwater environments, is unable to biosynthesize heme and requires exogenous heme. Furthermore, we provide genomic evidence for putative heme auxotrophy among many not-yet-cultured aquatic microbial groups. Heme should be the focus of future research on the metabolic dependency among microorganisms and the role of exchangeable metabolites in structuring diverse ecosystems, and would also be a media component that must be considered when cultivating novel microbes.
Infinitival complement clauses

Abstract
Assuming the Feature Reassembly Hypothesis (FRH) (Lardiere 2008, 2009), we argue that the acquisition of Exceptional Case Marking (ECM), Inflected Infinitive Structures (IIS) and Prepositional Infinitival Structures (PIC) by Spanish learners of European Portuguese (EP) presents different challenges. Two Acceptability Judgment Tasks show that identifying and reconfiguring the specific features associated with the PIC is a difficult task and that Spanish native speakers perform better in the case of ECM, whose properties can, for the most part, be transferred from the L1. However, the absence of an overt morphosyntactic counterpart for features related to Differential Object Marking (DOM) in EP represents a challenge. Finally, the results for the IIS present an interesting case study, since they force us to question the usual descriptions of the native grammar.
Brazilian and European Portuguese and Holmberg’s 2005 typology of null subject languages
Authors: Martins Ana Maria , Nunes Jairo 
Published: November 2021

Abstract
This paper rethinks Holmberg’s (2005) characterization of partial vs. consistent null subject languages (NSL) based on data from Brazilian and European Portuguese, the former a partial, the latter a consistent NSL. The paper proposes that rather than overt morphological distinctions, what is relevant for null subject licensing is the underlying feature specification of the verbal inflection, after agreement between T and a pronominal subject values the relevant person/number/gender/Case feature. Hence, only close inspection of the pronominal and agreement systems of individual NSLs permits an adequate characterization of them, for the same language may behave as a ‘partial’, ‘consistent’, or ‘radical’ NSL depending on the morphological feature specification of its nominative pronouns and T heads.
Prefaces in Soviet translations of Robert Burns’s poetry as ideological tools
Authors: Kaloh Vid Natalia 
Published: November 2021

AbstractThis article focuses on the ideological content and function of the prefaces that accompany the translations of foreign literature made in the Soviet Union. The aim of the article is to demonstrate how these translations use paratexts to comply with the target system’s ideological constraints. It shows how the ways in which the Soviet authorities used paratexts to manipulate representations of the author of the source text and the text itself reflect the power structures within the target system. The empirical investigation draws on a close lexical analysis of ideologemes in two prefaces that accompanied Soviet translations of Robert Burns’s poetry.
