An efficient BF3-promoted cyclization of α-amino acetals with alkynes for the assembly of substituted pyrroles has been developed. This cascade process can be easily achieved through a simple metal-free operation under mild conditions.
A Systematic Review and Meta-Analysis Exploring Effects of Third-Wave Psychological Therapies on Hearing-Related Distress, Depression, Anxiety, and Quality of Life in People With Audiological Problems

Purpose:
There is growing evidence supporting the use of third-wave psychological therapies, such as mindfulness-based interventions (MBIs) and acceptance and commitment therapy (ACT), for people with long-term or chronic physical health conditions. We conducted a systematic review and meta-analysis to critically evaluate the effectiveness of third-wave interventions for improving hearing-related distress and psychological well-being in people with audiological problems.

Method:
We searched online bibliographic databases and assessed study quality. We conducted random-effects meta-analyses if at least two randomized controlled trials (RCTs) examined hearing-related distress, depression, anxiety, or quality of life in people with audiological problems. Findings of pre–post studies were summarized narratively.

Results:

We identified 15 studies: six RCTs and nine pre–post studies. The methodological quality of studies was mostly poor to moderate, and sample sizes were typically small (overall
n
= 750). Most studies focused on tinnitus (
n
= 12), MBIs (
n
= 8), and ACT (
n
= 6). Statistically significant improvements in hearing-related distress were found with ACT and MBIs versus controls and other treatments at post-intervention in people with tinnitus, while improvements in depression and anxiety were only found for ACT versus controls at post-intervention. However, gains were either not maintained or not examined at follow-up, and there was no evidence for improvements in quality of life.

Conclusions:
At present, there is insufficient evidence to recommend the use of third-wave interventions for improving hearing-related distress or psychological well-being in people with audiological problems. There is some evidence that ACT and MBIs may be useful in addressing hearing-related distress in people with tinnitus, but only in the short term. However, findings should be interpreted with caution given the small number of studies with generally small sample sizes and mostly poor-to-moderate methodological quality. More high-quality, adequately powered, double-blind RCTs, particularly in audiological problems other than tinnitus, are needed to draw firm conclusions and meaningful clinical recommendations.

Schwere hämolytische Krankheit beim Fetus und Neugeborenen mit ungewöhnlich hohem Anti-D-Titer und prolongiertem Anämieverlauf
Authors: Ackerstaff Stefanie , Wolf Zsuzsanna , De Rop Christiane , Holzhäuer Inci , Fischer Johannes 
Published: May 2022

ZusammenfassungWir berichten über 2 Patienten mit schwerer hämolytischer Krankheit beim Fetus und Neugeborenen. Beide Mütter wiesen neben Anti-D-Antikörpern mit ungewöhnlich hohen Titern (Patientin 1:
1 048 576, Patientin 2: 16 384) weitere Allo-Antikörper auf und sie erhielten intrauterine Transfusionen im Rahmen ihrer Schwangerschaften. Kind 1 zeigte nach Geburt in der
Schwangerschaftswoche 32 + 1 einen Apgar-Score von 6 – 8 – 9 und einen Hämoglobin-Wert (Hb-Wert) von 11,7 g/dl, das Bilirubin lag in den ersten 3 Tagen bei maximal 9,2 mg/dl. Der
Anti-D-Titer lag nach Geburt bei 65 536 und fiel postnatal langsam ab (512 an Tag 80; 1 an Tag 140). Bei Kind 2 wurde nach Geburt in der Schwangerschaftswoche 35 + 2 ein Apgar-Score von
8 – 9 – 10 gemessen. Der Hb-Wert lag bei 13,7 g/dl und das Bilirubin stieg in den ersten Lebenstagen auf ein Maximum von 11,46 g/dl. Der kindliche Anti-D-Titer lag bei 1024. Die
Hyperbilirubinämie konnte in beiden Fällen mittels Phototherapie gut beherrscht werden und die Kinder wurden nach 4 bzw. 2 Wochen in gutem Allgemeinzustand entlassen. Allerdings zeigte sich
postnatal eine prolongierte hyporegenerative Anämie, sodass über 3 Monate (Kind 1) bzw. 1,5 Monate (Kind 2) weitere Transfusionen notwendig waren. Zwei Mechanismen werden als Ursache einer
prolongierten postnatalen Anämie diskutiert: Zum einen können persistierende Anti-D-Antikörper und intrauterine Transfusionen zu einer Verminderung der Erythropoese führen. Hiervon zu
unterscheiden ist eine späte hämolytische Anämie mit regenerierendem Knochenmark bei anhaltender immunhämatologischer Hämolyse. Diese Fälle zeigen, dass eine hyporegenerative Anämie über
Wochen nach Geburt andauern kann und die Kinder sorgfältig im Hinblick auf eine anhaltende Anämie beobachtet werden sollten. Neben der Bestimmung des Hb-Wertes sind auch die Bestimmung der
Retikulozytenzahl und des Anti-D-Titers indiziert, um den weiteren Verlauf und eine mögliche Regeneration des Knochenmarks vorherzusagen.

Published: May 2022

Abstract
Background Angiography relates the residual lumen to the poststenotic distal lumen (NASCET criterion) and expresses the result in percent lumen reduction. This method is not applicable when there is a collapse of the distal lumen, as seen in severe stenosis. The purpose of this study was to evaluate whether the reduced poststenotic caliber could be an additional sonographic criterion for estimation of the degree of stenosis.
Methods We measured the caliber of the distal lumen of the extracranial internal carotid artery (ICA) in 57 patients with low-grade stenosis <50% (NASCET criterion), and in 57 patients with unilateral stenosis of ≥ 50 %. All were classified following international recommendations. The criteria used included the poststenotic velocity to discriminate moderate to high-grade stenosis (50–70%) from very high-grade (≥ 80 %) stenosis. In addition, we measured the interrater reliability of the ultrasonic measurement of the lumen in the distal ICA.
Results In the group of patients with 50% to 70% stenosis, the distal lumen was 4.3 ± 0.6 mm. In the group with very high-grade stenosis ≥ 80%, the distal lumen was 2.6±0.5mm (p<0.0001). A distal lumen of 3.2 mm or less predicted a very high-grade stenosis with a sensitivity of 0.92 and a specificity of 0.96 (AUC 0.986; 95% CI 0.97–1.00; p=0.0001).
Conclusion The distal poststenotic lumen is an additional ultrasonic criterion to discriminate a very high-grade ICA stenosis from a lesser degree of ICA stenosis. It can help avoid misinterpretation due to the high variability of intrastenotic peak systolic velocities (PSV) in very high-grade ICA stenoses.

Published: May 2022

AbstractIntroduction Choanal polyps are benign lesions arising from the sinonasal mucosa, extending through the choana into the nasopharynx. Though polyps arising from the maxillary sinus and extending to the choana are common, polyps arising from the sphenoid sinus ostium, posterior part of middle turbinate, and inferior and middle meatus are quite uncommon.Objective To document the site of origin of choanal polyps arising from unusual sites; their clinical, radiological, and histopathological characteristics, as well as diagnostic challenges and management.Methods This retrospective, single-center study included 14 patients aged 16 to 75-years-old with choanal polyps. After obtaining informed consent, their clinical, radiological and surgical details and histopathology reports were reviewed. Patients were followed for at least 6 months after surgery.Results The predominant symptoms were unilateral nasal obstruction (n = 9), snoring, rhinorrhea, and epistaxis. Though anterior rhinoscopy was unremarkable, a mass could be visualized during posterior rhinoscopy in the nasopharynx in 11 patients, and a mass could be directly visualized in the oropharynx in 2 patients. After diagnostic by nasal endoscopy, these polyps were noted to arise from the posterior aspect of the middle meatus (n = 6), middle turbinate (n = 3), posterior septum (n = 3), sphenoid sinus ostium (n = 1), and inferior meatus (n = 1). All patients were managed surgically. The histopathological examination revealed inflammatory polyp (n = 12), actinomycosis (n = 1), and rhinosporidiosis (n = 1). Patients were followed up for 6 to 22 months. We observed no complications or recurrence.Conclusion Diagnostic nasal endoscopy should be performed in all patients presenting with nasal obstruction, to rule out choanal polyps arising from unusual sites. Complete polyp removal and appropriate treatment based on histopathology prevents recurrence.
Using network analyses to examine the extent to which and in what ways psychology is multidisciplinary
Authors: Fujita Yoshiaki , Vitevitch Michael S. 
Published: May 2022

AbstractThe emerging field known as the “science of science” uses a variety of quantitative techniques to (among other things) understand how a specific field changes over time. The tools of network science were used to quantify the extent to which Psychology is multidisciplinary, and how the extent to which it is multidisciplinary changed over time. Citation networks were created from all of the articles published in journals identified by the Web of Science as Multidisciplinary-Psychology for each year from 2008 to 2018. Nodes in the networks represented Multidisciplinary-Psychology journals, and connections were placed to other journals (i.e., nodes) that were cited in the Multidisciplinary-Psychology articles for each year. The citation networks showed that about 25% of the citations were to other Multidisciplinary-Psychology journals, about 50% of the citations were to Psychology journals in other sub-fields, and about 25% of the citations were to journals in other disciplines. This distribution of citations remained fairly consistent across the years examined. To identify the ways in which Psychology is multidisciplinary, clusters of nodes (known as modules) in each citation network were detected to identify possible research themes that were examined further with co-word networks made from the author-provided keywords in each of the Multidisciplinary-Psychology articles that appeared in each Module. Some research topics persisted in the years examined, whereas other topics were more transient. Given that multidisciplinary research did not increase over time but instead changed in areas of research focus, ways for academic and research administrators to foster and continually renew multidisciplinary research are discussed. The discussion also describes how individual researchers might use the techniques here to identify areas of research that are less commonly explored and may prove to be fruitful areas to shift their research focus. The same techniques can be used to provide insight in to other disciplines in the Humanities and Social Sciences.

Published: May 2022

The exploration of non-collinear spin texture in the f-electron-based rare-earth magnets has attracted fascinating interest for its fundamental physics and potential spintronic applications. Here, the real-space observation of nanometric helical spin order with the period down to 20 nm in centrosymmetric TbGa magnets was presented by Lorentz transmission electron microscopy. It was found that the helical period and the initial temperature for the appearance of the periodic helix can be tuned by the thickness of single-crystal TbGa plates (71–169 nm). Furthermore, the domain evolution under the perpendicular magnetic fields and with the shape constriction reveals the high stability of the stripe domains.
Unlocking Gippsland reserves with a minimum kit solution – West Barracouta
Authors: Kubik John , Shaw Grant , Vicario Melissa 
Published: May 2022

The West Barracouta (BTW), field one of the largest proven undeveloped gas fields off the south-eastern Australian coast, commenced production in April 2021. The project was developed by Esso-BHP Gippsland Basin Joint Venture (JV), a 50–50 JV between ExxonMobil’s subsidiary Esso Australia and BHP Petroleum. The BTW gas field is situated ~6 km south west of the existing Barracouta gas field and platform, the first Gippsland Basin Joint Venture platform in Bass Strait. The BTW development involved drilling two subsea production wells, installation of umbilical controls from the existing platform and installation of a ~6 km subsea flowline to connect to existing gas pipeline via a hot tap. The BTW team will share insights on how it: (1) utilised minimum kit solution and verification of existing asset condition; subsea hot tap into operational gas pipeline and re-use of existing platform J-tube to minimise works on and around the Barracouta Platform (including diving work). (2) Managed an Operator first – co-mingled wet gas subsea pipelines while operating in hydrate regions; via detailed water detection metre/software solution, downhole zone isolation and systematic operating guidelines. (3) Leveraged Installation Contractor competitive Front End Engineering and Design (FEED) enabling optimisation of facilities design/execution strategies to align with strengths and maximise overall project value. (4) Leveraged the OneSubsea/Subsea 7 Subsea Integration Alliance and global worldwide network to execute the subsea design (including qualification), manufacture and installation. (5) Utilised the incumbent Engineering, Procurement and Construction (EPC) contractor to integrate the subsea and topsides control systems to support a single operation system linked to the existing to Distributed Control System (DCS).
Gaze following requires early visual experience

Published: May 2022

SignificanceEarly in life, humans spontaneously learn to extract complex visual information without external guidance. Current vision models fail to replicate such learning, relying instead on extensive supervision. A classic example is gaze understanding, an early-learned skill useful for joint attention and social interaction. We studied gaze understanding in children who recovered from early-onset near-complete blindness through late cataract surgery. Following treatment, they acquired sufficient visual acuity for detailed pattern recognition, but they failed to develop automatic gaze following. Our computational modeling suggests that their learning is severely limited due to reduced availability of internal self-supervision mechanisms, which guide learning in normal development. The results have implications to understanding natural visual learning, potential rehabilitation, and obtaining unsupervised learning in vision models.
Rotating hybrid stars with color-flavor-locked quark matter
Authors: Sen Debashree , Chaudhuri Gargi 
Published: May 2022

Abstract
In the present work we achieve phase transition from β stable hadronic matter to color-flavor locked (CFL) quark matter with Maxwell construction. The hybrid equation of state (EoS), obtained for different values of bag pressure B and gap parameter Δ, have been used to compute the speed of sound in hybrid star (HS) matter. The structural properties of HSs in both static and rotating conditions have been calculated in light of various constraints from different astrophysical and empirical perspectives. The effects of B and Δ on the EoS and structural properties have been investigated. At a certain density, shortly after phase transition, the HSs become unstable. In static conditions, the mass-radius solutions satisfy the constraints from GW190425, NICER experiment for PSR J0030+0451 and PSR J0740+6620 and from massive pulsars like PSR J0348+0432 and PSR J0740+6620. In rapidly rotating conditions at Kepler frequency, the constraints on maximum mass from the secondary component of GW190814 and that on rotational frequency from fast pulsars like PSR B1937+21 and PSR J1748−2446ad are all satisfied. In slowly rotating conditions, the universality relations in terms of normalized moment of inertia also hold quite well for most of our HS configurations.
Antenna designing for efficient rectenna solar cells
Authors: Muhibbullah M , Alhazime Ali A , Amin Muhammad , El-Zohary Salah E 
Published: May 2022

Abstract
The rectenna solar cell is considered to be one of the best photovoltaic devices due its effective light to electric energy conversion performance. New ideas are needed to improve the design of efficient rectenna solar cells. In this paper, we have described a novel design of an antenna associated with a rectifier. Solar spectrum contains radiation of different wavelengths and intensities. The intensity of solar radiation is maxima at around the 500 nm wavelength. The monopole antenna of the length 125 nm (dipole of the length 250 nm) converts the maximum energy of the solar spectrum. Metallic behaving nano rods may be better as the antenna. The carriers of the nano rod should remain free from any bias for highly efficient rectenna solar cells. The pn junction should be used as a rectifier in the rectenna solar cells to get better receiving power. The rectifier(s) position may keep a role to increase the receiving power. Furthermore, we proposed some important analytical investigations that could help to optimize the antenna carrier density.

NPs were noticed. The spherical morphologies and particle sizes were observed using scanning electron microscopy (SEM), and the elemental composition was found using energy dispersive x-ray (EDX) spectroscopy. The FT-IR spectra showed significant absorption bands, and the values of Debye temperature (θ
D) increased with the doping of Mn2+ content and an increase in the lattice vibrations. UV-visible diffuse reflectance spectroscopy (DRS) was used to find the optical energy bandgap values from 1.87 to 1.98 eV. The magnetic properties were evaluated using a vibrating sample magnetometer (VSM). Significant variations between the experimental and theoretical magnetic moments were observed, suggesting that the present system showed Yafet-Kittel type magnetic ordering.
Reionization process dependence of the ratio of CMB polarization power spectra at low-ℓ
Authors: Kitazawa Noriaki 
Published: May 2022

Abstract
We investigate
how much the ratio of cosmic microwave background (CMB) polarization power spectra CBB
ℓ
/CEE
ℓ
at low-ℓ (ℓ ≲ 10) depends on the process of reionization.
Both such low-ℓ B-mode and E-mode polarization powers
are dominantly produced by Thomson scattering of CMB photons off the free electrons
which are produced in the process of reionization.
Since the reionization should be finished until at least the redshift z ≃ 6
and the low-ℓ polarization powers are produced at late time,
the ratio is rather insensitive by the ionization process at higher redshifts,
but it is sensitive to the value of optical depth.
The value of the ratio at ℓ = 2, however,
is almost insensitive to the reionization process including the value of optical depth,
and the value is approximately half of the value of tensor-to-scalar ratio.
This fact can be utilized for future determination of tensor-to-scalar ratio
in spite of the ambiguity due to cosmic variance.
Deciphering signatures of Bardeen black holes from the observed quasi-periodic oscillations
Authors: Banerjee Indrani 
Published: May 2022

Abstract
Quasi-periodic oscillations (QPOs) observed in the power spectrum of black holes are unique observational probes to the background spacetime since they can be directly related to the timescales associated with the motion of matter orbiting in the vicinity of the black hole horizon. In this regard, the high frequency QPOs (HFQPOs) are particularly interesting as they occur in commensurable pairs, the most common ratio being the 3:2 twin peak QPOs. The theoretical models which aim to explain these QPOs express the observed frequencies in terms of the epicyclic motion of test particles in a given background spacetime. In this work, we study the signatures of Bardeen spacetime from the observed QPOs in the black hole power spectrum. Bardeen black holes are rotating, regular black holes with a magnetic monopole charge. Such regular backgrounds are theoretically interesting as they can potentially evade the curvature singularity, otherwise unavoidable in general relativistic black holes. We perform a χ2 analysis by comparing the available observations of the quasi-periodic oscillations from black hole sources with the relevant theoretical models and note that the Kerr black holes in general relativity are observationally more favored compared to black holes with a monopole charge. Our analysis reveals that black holes with very high monopole charges are disfavored from QPO related observations.
