Published: May 2022

Context. Ground-based transit observations are affected by both telluric absorption and instrumental systematics, which can affect the final retrieved transmission spectrum of an exoplanet. To account for these effects, a better understanding of the impact of different data analyses is needed to improve the accuracy of the retrieved transmission spectra.
Aims. We propose validating ground-based low-resolution transmission spectroscopy using transiting white dwarfs. These targets are selected to have transit parameters comparable with typical transiting hot Jupiters but nondetectable transmission signals due to their extremely high surface gravities. The advantage here is that we know beforehand what the final transmission spectrum should be: a featureless flat spectrum.
Methods. We analyzed two transiting white dwarfs analogous to hot Jupiters, KIC 10657664B and KIC 9164561B. We used various noise models to account for the systematic noise in their spectroscopic light curves following common procedures of transmission spectroscopy analyses. We compared the derived transmission spectra with the broadband transit depth to determine whether there are any artificial offsets or spectral features arising from light-curve fitting.
Results. The results show a strong model dependence, and the transmission spectra exhibit considerable discrepancies when they are computed with different noise models, different reference stars, and different common-mode removal methods. Nonetheless, we can still derive relatively accurate transmission spectra based on a Bayesian model comparison.
Conclusions. With current ground-based instrumentation, the systematics in transit light curves can easily contaminate a transmission spectrum, introducing a general offset or some spurious spectral features and thus leading to a biased interpretation on the planetary atmosphere. Therefore, we suggest that any wiggle within the measurement errors in a transmission spectrum should be interpreted with caution. It is necessary to determine the dependence of results on the adopted noise model through model comparison. The model inferences should be examined through multiple observations and different instruments.

Published: May 2022

Context.The primary alcohol n-propanol (i.e., normal-propanol or propan-1-ol; C3H7OH) occurs in five different conformers: Ga,Gg, Gg', Aa, andAg.All rotational spectra of the three conformers of theGfamily are well described, making astronomical search of their spectroscopic signatures possible, as opposed to those of the Aa andAgconformers.Aims.Our goal is to facilitate the astronomical detection ofAaandAgconformers of n-propanol by characterizing their rotational spectra.Methods.We recorded the rotational spectra of n-propanol in the frequency domain of 18-505 GHz. Additional double-modulation double-resonance (DM-DR) measurements were performed, more specifically with the goal to unambiguously assign weak transitions of theAaconformer and to verify assignments of theAgconformer.Results.We derived a spectroscopic quantum mechanical model with experimental accuracy (withJmax= 70 andKa,max= 6) forAa n-propanol. Furthermore, we unambiguously assigned transitions (withJmax= 69 andKa,max= 9) ofAgn-propanol; in doing so, we prove the existence of two tunneling states,Ag+and Ag−.Conclusions.The astronomical search of all five conformers of n-propanol is now possible via their rotational signatures. These are applied in a companion article on the detection of n-propanol toward the hot molecular core Sgr B2(N2).
Optimal semigroup regularity for velocity coupled elastic systems: a degenerate fractional damping case
Authors: Kuang Zhaobin , Liu Zhuangyi , Tebou Louis 
Published: May 2022

In this note, we consider an abstract system of two damped elastic systems. The damping involves the average velocity and a fractional power of the principal operator, with power θ in [0, 1], The damping matrix is degenerate, which makes the regularity analysis more delicate. First, using a combination of the frequency domain method and multipliers technique, we prove the following regularity for the underlying semigroup:

The semigroup is of Gevrey class δ for every δ > 1/2θ, for each θ in (0, 1/2).
The semigroup is analytic for θ = 1/2.
The semigroup is of Gevrey class δ for every δ > 1/2(1 — θ), for each θ in (1/2, 1).

Next, we analyze the point spectrum, and derive the optimality of our regularity results. We also prove that the semigroup is not differentiable for θ = 0 or θ = 1. Those results strongly improve upon some recent results presented in Ammari et al. [J. Evol. Equ. 21 (2021) 4973-5002].

Published: May 2022

AbstractCongenital diarrheal disorders (CDDs) are a heterogeneous group of inherited
diseases that typically occur in the first weeks of life or can present later in
life after the introduction of different nutrients; they can cause
life-threatening severe dehydration and electrolyte disturbances. This study was
conducted to characterize the causes of monogenic CDDs, and their clinical
consequences. Clinical characteristics of 31 patients with CDDs that occurred in
the first month of life and lasted more than 2 weeks were analyzed
retrospectively. The patients were divided into groups according to the current
CDD classification. The rate of consanguinity among parents was 77.4%.
Of the patients, 16 (51.6%) were female and 15 (48.4%) were
male. The underlying genetic defect was determined in 26 (83.9%)
patients. The most common etiologic factors were digestive disorders of food and
absorption and transport of electrolytes (58.1%, 18/31) (most of
them being carbohydrate malabsorption disorders, 12/18) and intestinal
immune system disorders (9.6%, 3/31). Total parenteral nutrition
(TPN) was given to 45.2% (14/31) of the patients. Mortality rate
was 28.5% (8/28). In conclusion, early diagnosis and treatment
of CDDs with high morbidity and mortality is extremely important in terms of
prognosis. Clinical and laboratory findings, stool characteristics,
histopathological findings and the effects of dietary therapy are the primary
and most important steps that lead to accurate diagnosis. In addition, advanced
diagnostic possibilities, including genetic analyses, are essential for
diagnosing underlying diseases.

Abstract
Objective It is known that the single embryo transfer (SET) is the best choice to reduce multiples and associated risks. The practice of cryopreserving all embryos for posterior transfer has been increasingly performed for in vitro fertilization (IVF) patients at the risk of ovarian hyperstimulation syndrome or preimplantation genetic testing for aneuploidy. However, its widespread practice is still controverse. The aim of this study was to evaluate how effective is the transfer of two sequential SET procedures compared with a double embryo transfer (DET) in freeze-only cycles.
Methods This retrospective study reviewed 5,156 IVF cycles performed between 2011 and 2019, and 506 cycles using own oocytes and freeze-only policy with subsequent elective frozen-thawed embryo transfers (eFET) were selected for this study. Cycles having elective SET (eSET, n = 209) comprised our study group and as control group we included cycles performed with elective DET (eDET, n = 291). In the eSET group, 57 couples who had failed in the 1st eSET had a 2nd eFET, and the estimated cumulative ongoing pregnancy rate was calculated and compared with eDET.
Results After the 1st eFET, the ongoing pregnancy rates were similar between groups (eSET: 35.4% versus eDET: 38.5%; p = 0.497), but the estimated cumulative ongoing pregnancy rate after a 2nd eFET in the eSET group (eSET + SET) was significantly higher (48.8%) than in the eDET group (p < 0.001). Additionally, the eSET + SET group had a 2.7% rate of multiple gestations, which is significantly lower than the eDET group, with a 30.4% rate (p < 0.001).
Conclusion Our study showed the association of freeze-only strategy with until up to two consecutive frozen-thawed eSETs resulted in higher success rates than a frozen-thawed DET, while drastically reducing the rate of multiple pregnancies.

Published: May 2022

Abstract
Objective To evaluate whether colposcopy-directed biopsy is necessary to increase the accuracy of diagnosing cervical intraepithelial lesions in relation to colposcopy.
Methods We performed a retrospective, observational study by analyzing medical records obtained from Hospital de Clínicas do Paraná from February 2008 to February 2018. Patients with results of Pap tests, colposcopy, colposcopy-directed biopsy, and surgical procedures (high-frequency surgery or cold conization) were included. Data such as quadrants involved during colposcopy and age differences were also analyzed.
Results A total of 299 women were included. Colposcopy was found to have an accuracy rate of 76.25% (95% confidence interval [CI], 71.4–81.1). Among the highest-grade lesions, the accuracy rate was 80.5% (95% CI, 75.7–85.3). The accuracy rates for biopsy were 79.6% (95% CI, 75–84.2) and 84.6% (95% CI, 80–89.1) for the highest-grade lesions. High-grade lesions were accurately confirmed in 76.9% and 85% of patients with 1 and 2 or more affected quadrants, respectively. For women younger than 40 years, the accuracy rates were 77.6% and 80.8% for colposcopy and biopsy, respectively. For women 40 years or older, the accuracy rates were 72.5% and 76.3% for colposcopy and biopsy, respectively.
Conclusion There is no difference between the accuracy of colposcopy and that of biopsy in diagnosing cervical intraepithelial lesions in relation with the result of conization. The patients who received the greatest benefit when biopsy was not performed were those with high-grade lesions at colposcopy, a lesion involving 2 or more quadrants, and those younger than 40 years.

ResumoO principal objetivo desta pesquisa foi fazer uma comparação intraindividual dos resultados entre as técnicas de incisão ulnar aberta e retinaculótomo de Paine com incisão palmar em pacientes com síndrome do túnel do carpo (STC) bilateral. Os pacientes foram submetidos à cirurgia aberta em uma mão e cirurgia com retinaculótomo de Paine na mão contralateral. Os pacientes foram avaliados com o Boston carpal tunnel questionnaire, escala visual analógica para dor e força de preensão palmar, pinça lateral, pinça polpa-polpa e trípode. As duas mãos foram examinadas antes da cirurgia e 2 semanas, 1 mês, 3 e 6 meses após a cirurgia. Dezoito pacientes (36 mãos) foram avaliados. As pontuações da escala de gravidade dos sintomas (EGS) foram maiores no pré-operatório nas mãos submetidas à cirurgia com retinaculótomo de Paine (p = 0,023), mas menores no 3° mês após o procedimento (p = 0,030). As pontuações da escala de estado funcional (EEF) foram menores às 2 semanas, 3 meses e 6 meses (p = 0,016) nas mãos submetidas à cirurgia com retinaculótomo de Paine. Em um estudo de módulo de diferença de dois grupos, o grupo submetido à cirurgia com retinaculótomo de Paine apresentou pontuações médias de EGS na 2ª semana e 1° mês e de EEF na segunda semana inferiores a 0,8 e 1,2 pontos, respectivamente, em comparação ao grupo submetido ao procedimento aberto. As mãos submetidas à cirurgia com retinaculótomo de Paine apresentaram escores significativamente menores de EGS em 3 meses e de EEF em 2 semanas, e aos 3 e 6 meses após a cirurgia em comparação a técnica aberta.

Published: May 2022

AbstractPreconception care (PCC) involves a wide-ranging set of interventions to optimize health prior to pregnancy. These interventions seek to enhance conception rates, pregnancy outcomes, childhood health, and the health of future generations. To assist health care providers to exercise high-quality clinical care in this domain, clinical practice guidelines from a range of settings have been published. This systematic review sought to identify existing freely accessible international guidelines, assess these in terms of their quality using the AGREE II tool, and assess the summary recommendations and the evidence level on which they are based. We identified 11 guidelines that focused on PCC. Ten of these were classified as moderate quality (scores ranging from 3.5 to 4.5 out of 7) and only one was classified as very high quality, scoring 6.5. The levels of evidence for recommendations ranged from the lowest possible level of evidence (III) to the highest (I-a): the highest quality evidence available is for folic acid supplementation to reduce risk of neural tube defects and the role of antiviral medication to prevent HIV transmission. This systematic review identified that high-quality guidelines on PCC are lacking and that few domains of PCC recommendations are supported by high-quality evidence.
Interventional Pulmonology and Esophagus: Combined Endobronchial Ultrasound and Endoscopic Ultrasound for Mediastinal Staging
Authors: Khalid Sameeha , Hegde Pravachan 
Published: May 2022

AbstractEndoscopic ultrasound (EUS) techniques in addition to endobronchial ultrasound (EBUS) can lead to diagnosis and complete accurate staging of the mediastinum in a single session. This allows for decreased health care costs, less delay in diagnosis and treatment, reduced patient discomfort, and decreased morbidity compared with invasive surgical staging techniques. In comparison to conventional mediastinoscopy, the cost-effectiveness and reduced complication profile of the endoscopic approach has made this a superior initial step in the staging and diagnosis of lung cancer. Moreover, compared with EBUS alone, combined EUS and EBUS has significantly increased yield, as well as diagnostic sensitivity making a combined approach preferable as the emerging gold-standard technique for initial minimally invasive mediastinal staging. We discuss the advantage of using EUS in combination with EBUS and highlight techniques, lymph node landmarks, utility in staging and restaging of the mediastinum, roles in diagnosing mediastinal infections and granulomatous lesions, and future directions in endosonography.
Wake-up-free properties and high fatigue resistance of HfxZr1−xO2-based metal–ferroelectric–semiconductor using top ZrO2 nucleation layer at low thermal budget (300 °C)

Published: May 2022

Ferroelectricity and crystallinity of TiN/ZrO2/HfxZr1−xO2 (Hf:Zr = 0.43:0.57; HZO)/SiO2/Si metal–ferroelectric–semiconductor (MFS) capacitors with a top ZrO2 nucleation layer fabricated by low-temperature processes at 300 °C of atomic layer deposition and post-metallization annealing (PMA) were systematically investigated. The HZO (10 nm)-based MFS capacitors without (w/o) and with 2- and 10-nm-thick ZrO2 films (ZrO2-2 nm and ZrO2-10 nm, respectively) were found to form an extremely thin SiO2 interfacial layer (SiO2-IL) with a thickness of one or two monolayers. The HZO film in the TiN/ZrO2/HZO/SiO2/Si capacitors formed the ferroelectric orthorhombic phase even with a low thermal budget of 300 °C; in contrast, that of the w/o capacitor exhibited a predominantly amorphous structure. This result is attributed to the polycrystalline ZrO2 film acting as a nucleation layer for the crystallization of an amorphous HZO film during PMA treatment. Therefore, the remnant polarization (2Pr) increased in the order of w/o (2.2 µC/cm2) &lt; ZrO2-2 nm (6.8 µC/cm2) &lt; ZrO2-10 nm (15 µC/cm2). The endurance properties of the ZrO2-10 nm capacitor were free from the wake-up effect and exhibited less degradation because of the insertion of a thick ZrO2 film of 10 nm at the TiN/HZO interface, which promoted the preferential formation of the ferroelectric orthorhombic phase and prevented the formation of oxygen vacancies at the ZrO2/HZO interface. These results suggest that superior ferroelectricity with wake-up-free properties and higher fatigue resistance of HZO-based MFS capacitors can be achieved by a low-temperature fabrication technique (300 °C) using a top ZrO2 nucleation layer.
Characterization of the incense sacrificed to the sarira of Sakyamuni from Famen Royal Temple during the ninth century in China
Authors: Ren Meng , Ren Xinlai , Wang Xinyi , Yang Yimin 
Published: May 2022

SignificanceIncense has been linked to ceremonies, religions, medicines, and cosmetics worldwide for thousands of years. While Chinese texts in the Tang dynasty (618 to 907 CE) indicate that numerous exotic aromatic substances were already being introduced into China through the land and maritime Silk Road, this has been rarely demonstrated archaeologically. This study identifies three types of incense associated with the sacred sarira of Sakyamuni Budda from the underground palace of Famen Royal Temple in central China, providing direct evidence of aromatics including elemi, agarwood, and frankincense as well as their composite product, namelyHexiang(blending of aromatics), in Buddhist activities, which may have promoted the spread of incense and the development of aromatic knowledge systems in medieval China.
Mars’ emitted energy and seasonal energy imbalance

Published: May 2022

SignificanceThe radiant energy budget is a fundamental metric for planets. Based on the observations from multiple missions, we provide a global picture of Mars’ emitted power. Furthermore, we estimate the radiant energy budget of Mars, which suggests that there are energy imbalances at the time scale of Mars’ seasons. Such energy imbalances provide a new perspective to understanding the generating mechanism of dust storms. Mars’ radiant energy budget is assumed to be balanced at all time scales in current models and theories, but our analyses show that the energy budget is not balanced, at least at the time scale of Mars’ seasons. Therefore, current theories and models should be revisited with the newly revealed energy characteristics.
Sojourner experiences and spatial repertoires
Authors: Sandbulte Jade , Canagarajah Suresh 
Published: May 2022

AbstractResearch on translingual repertoires has highlighted the diverse semiotic resources that individuals access in communication, but little research has considered how spatial factors permit or limit access to these resources. Furthermore, as translingual studies have predominantly focused on interactional analysis, there is a paucity of studies on how social networks shape the repertoires of users. To fill this gap, we examine the communicative practices of an international spouse temporarily living in the United States. Through interview data and mobility maps, we analyze the participant’s subject positioning and its relation to his use of spatial resources in different spaces. Despite the participant’s low English proficiency, he engaged in conversations in many spaces through strategic employment of semiotic resources, including multiple languages and material objects. He also adopted certain positionings that afforded him more opportunities to interact. Thus, we argue that the usefulness of semiotic resources is tied to the spaces in which they are employed and that access to these resources is shaped by subject positioning.
Doing penance as a nexus of practice
Authors: Izadi Dariush 
Published: May 2022

Abstract
Funeral and mourning rites capture so many aspects of the Iranian traditional and religious rituals and provide
members of society with cultural tools of lamenting the dead. The study presents socio-cultural considerations in connection with
social space and action, linguistic interactions, and semiotic resources of rituals used in mourning ceremonies for Shiite Muslims
in the city of Nur, Iran. The paper relies on a mediated discourse analysis approach as a theoretical framework from which to
develop a semiotic analysis of the linguistic practices and mediational means that appear in the mourning events. To this end, I
shall draw upon video and audio recorded interactions of mourning rituals personally collected at funerals. The paper demonstrates
that while mourning rituals are culturally and religiously framed in Shiite Muslims, one must also include the social space, the
discourse cycle, the trajectories of the material resource of individual’s historical bodies and of text.
The sound of absent-presence
Authors: Deumert Ana 
Published: May 2022

AbstractThis article engages with the theme of the proposed special issue in a perhaps unexpected way: for me, the ‘translinguistic movement’ is a pertinent reminder to move beyond the boundaries of language and other visible/audible modalities that are involved in semiosis. It also encourages us to move beyond the naïve empiricism that has shaped sociolinguistic work over the decades. The ‘sociolinguistics of the spectre’ that I develop in this article is rooted in philosophies of radical empiricism; it acknowledges the sensuous and affective nature of social life, and refuses to work with the ‘boundaries, binaries and demarcations’ that are located within the temporal ‘linearity of modernity’ (Garuba, 2013). In doing so, I will look at a particular time-space: the postcolony. It is a time-space where the ghosts of the past are ever-present and shape translinguistic practices; a time-space where time is always somehow ‘out-of-joint’.
