Published: September 2022

AbstractFerroelectrets (also called piezoelectrets) are relatively young members in the family of piezo‐, pyro‐ and ferroelectric materials. They exhibit ferroic behaviour phenomenologically undistinguishable from that of traditional ferroelectrics, although the materials per se are essentially non‐polar space‐charge electrets with artificial macroscopic dipoles (i.e. internally charged cavities). Since ferroelectrets not only represent a scientific curiosity but also have great application potential, they have attracted tremendous attention from science and industry. The research and development of ferroelectrets has witnessed significant progress in the past few years. New ferroelectrets with large transverse piezoelectric activity, biodegradable ferroelectrets as well as 3‐D printed ferroelectrets are reported. Charging methods of high efficiency are proposed based on better understanding of the physico‐chemical processes during charging. New insights into the piezoelectricity of ferroelectrets are provided. The development of ferroelectret‐based piezoelectric‐magnetic multimodal transducer films opens up new avenues for the research of ferroelectrets. Particularly, more and more novel applications of ferroelectrets in flexible pressure sensors, health monitoring, energy harvesting, air‐coupled ultrasonic non‐destructive testing etc. are reported. Here, these exciting recent advancements in the field of ferroelectret research are reviewed and discussed.

Published: September 2022

AbstractSowing is an important link in agricultural production and the basis for ensuring high yields and bumper harvests. Agriculture requires precision plows with good performance and stable work. However, the seeding process is in a completely closed state, and the operator relies mainly on experience to judge the operating state and performance of the plow. The purpose of this study is to analyse the analysis and research methods of the precision planter monitoring system based on mobile communication technology. In this study, a relatively advanced target detection algorithm based on prediction and mobile communication technology is adopted. The Kalman filter is applied to the precision planter monitoring tradition, in order to realise a more complete and customisable automatic monitoring system. The intelligent monitoring system and the corn precision planter can realise the stepless regulation of the planting spacing within 10–30 cm through the experimental design of three plant spacing parameter schemes of 10 , 20 and 30 cm. Its various operational performance indicators have met the standards stipulated by the state.

Context. The star formation rate (SFR) is a key ingredient for studying the formation and evolution of galaxies. Being able to obtain accurate estimations of the SFR, for a wide range of redshifts, is crucial for building and studying galaxy evolution paths over cosmic time.
Aims. Based on a statistical sample of galaxies, the aim of this paper is to constrain a set of SFR calibrators that are able to work in a large redshift range, from z = 0 to z = 0.9. Those calibrators will help to homogenize SFR estimations of star-forming galaxies and to remove any possible biases from the study of galaxy evolution.
Methods. Using the VIMOS Public Extragalactic Redshift Survey (VIPERS), we estimated a set of SFR based on photometric and spectroscopic data. We used, as estimators, photometric bands from ultraviolet (UV) to mid-infrared (mid-IR), and the spectral lines Hβ, [O II]λ3727, and [O III]λ5007. Assuming a reference SFR obtained from the spectral energy distribution reconstructed with Code Investigating GALaxy Emission (CIGALE), we estimated the reliability of each band as an SFR tracer. We used the GALEX-SDSS-WISE Legacy Catalog (GSWLC, z <  0.3) to trace the dependence of these SFR calibrators with redshift.
Results. The far and near UV (FUV and NUV, respectively), u-band and 24 μm bands, as well as LTIR, are found to be good SFR tracers up to z ∼ 0.9 with a strong dependence on the attenuation prescription used for the bluest bands (scatter of SFR of 0.26, 0.14, 0.15, 0.23, and 0.24 dex for VIPERS, and 0.25, 0.24, 0.09, 0.12, and 0.12 dex for GSWLC). The 8 μm band provides only a rough estimate of the SFR as it depends on metallicity and polycyclic aromatic hydrocarbon properties (scatter of 0.23 dex for VIPERS). We estimated the scatter of rest-frame luminosity estimations from CIGALE to be 0.26, 0.14, 0.12, 0.15, and 0.20 dex for FUV, NUV, ugriz, Ks, and 8–24 μm-LTIR. At intermediate redshift, the Hβ line is a reliable SFR tracer (scatter of 0.19 dex) and the [O II]λ3727 line gives an equally good estimation when the metallicity from the R23 parameter is taken into account (0.17 for VIPERS and 0.20 dex for GSWLC). A calibration based on [O III] retrieves the SFR only when additional information such as the metallicity or the ionization parameter of galaxies are used (0.26 for VIPERS and 0.20 dex for GSWLC), diminishing its usability as a direct SFR tracer. Based on rest-frame luminosities estimated with CIGALE, we propose our own set of calibrations from FUV, NUV, u-band, 8, 24 μm, LTIR, Hβ, [O II], and [O III].

Published: September 2022

Context. The electrodynamic interaction between the Galilean satellites and the Jovian magnetosphere generates Alfvén wings that connect the satellites to the polar atmosphere of Jupiter and induce auroral radiation through the cyclotron-maser instability. The satellite control of the Jovian decametric emission is widely known and has been studied since the 1960s, being first discovered with regard to Io and, more recently, Ganymede. The partial control of these emission by Europa and Callisto, however, has not yet been confirmed, however, hints of this control have already been found.
Aims. The goal of this work is to search for evidence of control of the Jovian decametric emission by the satellite Europa.
Methods. For this purpose, we analyzed the extensive digital catalog of Jovian decametric emission detected by the Nançay Decameter Array from 1990 to 2020. We analyzed distributions of the occurrence probability of the emission not induced by Io nor by Ganymede as a function of Europa phase and of the Array’s longitude with regard to the Jovian central meridian of longitude.
Results. As a result, we selected 267 possible Europa-induced emission, from which 186 are from source A (Eu-A), 56 are from source C (Eu-C), and 25 are from source D (Eu-D). The general maximum frequency and duration of these emission are presented and compared to those of the other emission in the catalog and their average power is estimated as a function of the average power of the Io-induced emission.
Conclusions. We conclude that Europa, just as in the case of Io and Ganymede, induces a portion of the Jovian decametric emission.

Zusammenfassung
Ziel der Arbeit Menschen mit Paraplegie, Angehörige und
professionell Versorgende können mit ihrer Erfahrung und praktischen
Kenntnissen zur Entwicklung patientenorientierter, versorgungsrelevanter
Forschungsfragen beitragen. Um sie in die Entwicklung einer Forschungsagenda
einzubeziehen, hat die James Lind Alliance (JLA) einen etablierten Ansatz
entwickelt. Das Ziel dieser Studie ist die Entwicklung einer Forschungsagenda zu
Paraplegie infolge einer traumatischen Querschnittlähmung, in Anlehnung
an diesen Ansatz.
Methodik Es wurden vier aufeinander aufbauende Online-Befragungen unter
Menschen mit einer traumatisch bedingten Paraplegie, ihren Angehörigen
und professionell Versorgenden durchgeführt. In der ersten haben die
Teilnehmenden aus ihrer Sicht unbeantwortete Fragen frei formuliert. Diese
wurden zusammengefasst und dahingehend geprüft, ob sie bereits durch
Forschung beantwortbar sind. Die unbeantworteten Fragen wurden in weiteren
Befragungen schrittweise priorisiert: In der zweiten wurden sie auf einer
fünfstufigen Rating-Skala (1–5) hinsichtlich ihrer Relevanz
bewertet, um eine Shortlist aus den Fragen zu entwickeln, die mit einem
Mittelwert von über 4 bewertet wurden. In der dritten Umfrage wurden
daraus die Top 10 bestimmt, deren Rangordnung in der vierten Befragung ermittelt
wurde.
Ergebnisse Es wurden 38 unbeantwortete Forschungsfragen identifiziert (1.
Befragung; n=52). Davon wurden 26 Fragen als wichtig bewertet (2.
Befragung; n=53), aus denen 10 Fragen ausgewählt (3. Befragung;
n=17) und in eine Rangordnung gebracht wurden (4. Befragung;
n=12). Vier Prioritäten betreffen
Behandlungsmöglichkeiten der Querschnittlähmung oder damit
verbundener Gesundheitsprobleme, drei die Gestaltung der Gesundheitsversorgung
im Bereich der Hilfsmittel und der Implementierung von Forschung, zwei
adressieren Patientenfaktoren, die zur Verbesserung der eigenen Situation
beitragen und eine die Erforschung des Krankheitsverlaufs.
Schlussfolgerung Es wurden neun Fragestellungen priorisiert, die auf
Forschung zur Verbesserung der Lebens- und Versorgungssituation mit einer
Querschnittlähmung abzielen, während eine Frage die Heilung
adressiert. Die priorisierten Fragen sollten durch Forschung aufgegriffen
werden, damit Problemstellungen adressiert werden, die für Betroffene,
Angehörige und professionell Versorgende relevant sind.

Published: September 2022

Abstract
Objective To identify early available predictors for the long-term outcome
of patients after transsphenoidal surgery (TSS) in the management of
Cushing’s disease.
Methods This single-center, retrospective study included 93 consecutive
patients with Cushing’s disease (follow-up 12–129 months, mean
48, median 38) who underwent TSS (21 had previous operations elsewhere). Six
cases had early re-operation, and the resulting data were evaluated instead of
the respective first operation. During the postoperative course, serum cortisol
levels were assessed every four hours at least until the next morning. An
association of parameters with long-term outcomes was tested using binary
logistic regression. Receiver operating characteristic curves were used to
determine sensitivity, specificity, positive predictive value, and negative
predictive value of different cut-off values of serum cortisol in the
postoperative course in the event of recurrence after remission.
Results Eighty out of 93 patients (86%) showed postoperative
remission (after primary treatment, 60 out of 72 patients, 90.3%). Of
these, 8 patients (10%) developed recurrence of hypercortisolism.
Compared to patients with persisting long-term remission, those with recurrence
differed in cortisol levels starting from 4 pm on the day of surgery
plus an event of increasing cortisol during the early postoperative course
(“peak”). Binary logistic regression showed the association
between a peak of serum cortisol in the early postoperative course with an
increased probability of recurrence.
Conclusions Patients with a peak of serum cortisol in the early
postoperative course show an increased recurrence rate. A cut-off value of serum
cortisol for clear identification of patients with later recurrence could not be
determined.

Zusammenfassung
Ziel der Studie Es mangelt hierzulande an Erkenntnissen bzgl. der
Inanspruchnahme von und den Einstellungen zu Tests zum Nachweis von SARS-CoV-2.
Unsere Arbeit zielt darauf ab, diese Lücke zu verringern.
Methodik Die Daten entstammen einer
bevölkerungsrepräsentativen Onlinebefragung (24. August bis 3.
September 2021, n=3.075; mittleres Alter 44,5 Jahre). Die
Inanspruchnahme von und die Einstellungen zu den Covid-19-Tests wurden im Detail
quantifiziert.
Ergebnisse 79,1% der Befragten haben schon einmal einen
entsprechenden Test zum Nachweis von SARS-CoV-2 (primär
Antigen-Schnelltests im Schnelltestzentrum und Selbsttests) bzw. einen
Antikörpertest durchführen lassen. Mit Ausnahme der
Durchführung eines PCR-Tests wurde die Durchführung
entsprechender Tests nur selten als unangenehm empfunden. Am ehesten
würden die Befragten einen Antigen-Schnelltest im Schnelltestzentrum
bevorzugen. Hauptgründe für die Inanspruchnahme von Selbsttests
und auch von Antigen-Schnelltests in Schnelltestzentren waren jeweils: (i)
Schutz anderer Menschen, (ii) zur eigenen gesundheitlichen Vorsorge und (iii)
Reisen. Hingegen waren Hauptgründe für den Verzicht auf
Selbsttests/Antigen-Schnelltests im Betrieb/Ausbildungszentrum:
(i) Bereits geimpft gegen Covid-19/genesen von Covid-19, gefolgt von
(ii) dem Arbeitsplatz im Home-Office, und einem (iii) fehlenden wahrgenommenen
Nutzen. Mit dem Zugang zu den Testmöglichkeiten im
Betrieb/Ausbildungszentrum und den Schnelltestzentren waren jeweils
knapp 80% eher bzw. sehr zufrieden.
Schlussfolgerung Unsere Arbeit hat die Inanspruchnahme und einige Aspekte
der Einstellungen bzgl. der Tests zum Nachweis von SARS-CoV-2 in Deutschland im
Spätsommer 2021 beschrieben. Damals wurden derartige Testangebote schon
genutzt und überwiegend als wenig unangenehm empfunden. Der Schutz
anderer Menschen war dabei ein Hauptgrund für die Nutzung derartiger
Testangebote. Künftige Forschung in diesem Bereich ist
wünschenswert (z. B. bei Hochaltrigen und in Zeiten
entgeltlicher Corona-Schnelltests).
123-Iodine MIBG in the Assessment of Sympathetic Denervation in Ogilvie's Syndrome
Authors: Bhoil Amit , Vinjamuri Sobhan 
Published: September 2022

Abstract123-Iodine metaiodobenzylguanidine (I-123 MIBG) imaging is frequently used in the assessment of sympathetic innervation and autonomic dysfunction in patients with cardiac failure, neurodegenerative Parkinson's syndrome, multiple system atrophy, myotonic dystrophy, and diabetic mellitus. The etiology of pseudo-obstruction remains unknown with likely imbalance between sympathetic and parasympathetic innervation proposed as a hypothesis. We present a case demonstrating the utility of I-123 MIBG scintigraphy for evaluating a case of pseudo-obstruction requiring frequent hospitalization due to progressive complex autoimmune neurological disorder.

AbstractWarthin's tumor is a benign and frequently encountered salivary gland neoplasm. Bilaterality and multifocality are rare in Warthin's tumor. Synchronous cervical lymph nodal metastasis with unknown primary in a case of Warthin's tumor can raise a suspicion of primary malignancy of the parotid gland. We present a case of bilateral multifocal Warthin's tumor with synchronous squamous cell carcinoma metastasis to the cervical lymph node. 18F-fluorodeoxyglucose whole body positron emission tomography/computed tomography imaging showed hypermetabolic bilateral multifocal parotid lesions and metastatic cervical lymph node with unknown primary malignancy.
Synthesis of Linear Tetraquinanes by [3+2] Cycloaddition, Chemoselective Allylation of 7-Ketonorbornene, and Ring-Rearrangement Metathesis as Key Steps

Published: September 2022

AbstractA nine-step synthetic sequence to linear tetraquinanes involving [3+2] cycloaddition, chemoselective allylation, and ring-rearrangement metathesis as key steps is reported. A chemoselective allylation of 7-ketonorbornene was realized for the first time by using indium powder and allyl bromide. By this method, norbornene ketones can be selectively allylated in the presence of a cyclopentanone moiety to give good yields of monoallylated Barbier-type products.

Published: September 2022

AbstractPrimary central nervous system lymphomas (PCNSLs) are extranodal variant forms of non-Hodgkin lymphoma arising within the brain parenchyma, leptomeninges, or spinal cord. PCNSL can present with varied neurological symptoms and imaging findings, making diagnosis without biopsy difficult. PCNSLs are highly aggressive, causing rapid deterioration, but are responsive to chemotherapy and radiotherapy making early diagnosis important.Crossed cerebellar diaschisis (CCD) is mostly seen with cerebral cortex vascular insults and is rarely reported with thalamic lesions and even rarer with thalamic lymphoma. However, CCD has also been described in other brain tumors (including primary glioma), chronic subdural hematoma, congenital insults, intracranial infections, and various dementia subtypes.We present a rare case of thalamic lymphoma evaluated with positron emission tomography/computed tomography that showed hypermetabolism of thalamus and associated hypometabolism in ipsilateral cerebral cortex and contralateral cerebellum representing CCD.

Published: September 2022

AbstractLeptomeningeal carcinomatosis is a manifestation in which tumor cells migrate into meninges. Breast carcinoma presenting with leptomeningeal metastases is a rare phenomenon that can occur in an isolated form as well as with coexistent parenchymal brain metastases. The gold standard for diagnosis is cerebrospinal fluid analysis, while contrast-enhanced magnetic resonance imaging is the most commonly used imaging modality. Nuclear medicine imaging with flourine-18-fluorodeoxyglucose positron emission tomography/computed tomography has proved to be useful in detecting leptomeningeal metastases and, at times, even before anatomical changes occur. Here, we present a case of breast carcinoma presenting with both pachymeningeal and leptomeningeal metastases 10 years after treatment.
p-type to n-type conductivity transition in thermoelectric CoSbS
Authors: Kousar H. Sajida , Srivastava Divya , Karttunen Antti J. , Karppinen Maarit , Tewari Girish C. 
Published: September 2022

We demonstrate a p-type to n-type conductivity transition for thermoelectric CoSbS achieved by precisely controlling the sulfur vapor pressure during the sample synthesis. The p–n transition is experimentally confirmed by both the Seebeck coefficient and the Hall effect measurements. From the crystal structure refinements, the increase in the sulfur vapor pressure in the synthesis is weakly but steadily reflected in the occupancy factor of sulfur in the CoSbS lattice, while the p–n transition is seen as a peak in all the three lattice parameters, a, b, and c. Computationally, the situation could be simulated with first principle DFT calculations on compressed CoSbS. Without compression, DFT presents CoSbS as a p-type semiconductor with an indirect bandgap of 0.38 eV, while the pressure application results in an n-type semiconductor with decreased lattice parameters but the same indirect bandgap as in the uncompressed case. Experimentally, the thermal conductivity is strongly enhanced for sulfur-deficient samples, which could be due to larger phonon mean free paths. The sulfur loading significantly enhances the electrical conductivity while moderately decreasing the Seebeck coefficient such that the overall power factor is improved by a factor of 9 for the n-type sample and by a factor of 6 for the p-type sample, owing to the increased charge carrier density, although the performance is still relatively low. Thus, this study highlights CoSbS as a promising building block for thermoelectric devices based on its bipolar semiconductor nature with the possibility for both p-type and n-type doping with enhanced power factor.

Published: September 2022

Abstract
Effects of in-plane and out-of-plane external stress anisotropy of ferromagnetic thin film with in-plane and out-of-plane uniaxial anisotropy on the ferromagnetic resonance frequencies have been theoretically investigated by using ferromagnetic resonance method. It is shown that resonance frequency can be enhanced by increasing in-plane external stress anisotropy field and uniaxial anisotropy field, decreasing out-of-plane uniaxial anisotropy field. For out-of-plane external stress case, however, the resonance frequency and two critical fields have no significant change. Also, compared with the case of the in-plane external stress anisotropy, the FMR frequencies are smaller. Additionally, interesting features are obtained for the stress case and compared with the case of without stress. The obtained results provide further insights on the effect of external stress on the properties of ferromagnetic thin film.
