Abstract
Purpose
Surgical documentation is an important yet time-consuming necessity in clinical routine. Beside its core function to transmit information about a surgery to other medical professionals, the surgical report has gained even more significance in terms of information extraction for scientific, administrative and judicial application. A possible basis for computer aided reporting is phase detection by convolutional neural networks (CNN). In this article we propose a workflow to generate operative notes based on the output of the TeCNO CNN.

Methods
Video recordings of 15 cholecystectomies were used for inference. The annotation of TeCNO was compared to that of an expert surgeon (HE) and the algorithm based annotation of a scientist (HA). The CNN output then was used to identify aberrance from standard course as basis for the final report. Moreover, we assessed the phenomenon of ‘phase flickering’ as clusters of incorrectly labeled frames and evaluated its usability.

Results
The accordance of the HE and CNN was 79.7% and that of HA and CNN 87.0%. ‘Phase flickering’ indicated an aberrant course with AUCs of 0.91 and 0.89 in ROC analysis regarding number and extend of concerned frames. Finally, we created operative notes based on a standard text, deviation alerts, and manual completion by the surgeon.

Conclusion
Computer-aided documentation is a noteworthy use case for phase recognition in standardized surgery. The analysis of phase flickering in a CNN’s annotation has the potential of retrieving more information about the course of a particular procedure to complement an automated report.

Abstract
In the present study, we examined what kind of parenting style groups (defined by parental warmth, behavioral control, and psychological control) can be identified among contemporary Finnish mothers and fathers and how these parenting style groups are associated with parents’ symptoms of parental burnout. Gender differences in parenting style groups, and in their associations with parental burnout, were also investigated. The survey data were gathered from 1,471 Finnish parents (91.2% mothers). The results of k-means cluster analysis identified six different parenting style groups: authoritarian (13.5%), permissive (15.2%), psychologically controlling (19.4%), uninvolved (14.4%), controlling (12.4%), and authoritative (25.1%), with the authoritative parenting style being the most common. The identified parenting style groups were equally common for mothers and fathers. The results showed further that, independently of gender, parents applying the authoritarian parenting style experienced symptoms of parental burnout the most, whereas those with the authoritative or permissive style reported these symptoms the least. Based on the results, it is suggested that child health care and family centers should pay particular attention to potential risk groups such as parents reporting symptoms of parental burnout and parents characterized by an authoritarian parenting style.
The effects of advertisement disclosure on heavy and light Instagram users
Authors: Saternus Zofia , Weber Patrick , Hinz Oliver 
Published: May 2022

AbstractThe present study investigates the moderating effect of usage intensity of the social networking site (SNS) Instagram (IG) on the influence of advertisement disclosure types on advertising performance. A national sample (N = 566) participated in a randomized online experiment including a real influencer and followers in order to investigate how different advertisement disclosure types affect advertising performance and how usage intensity moderates this effect. We find that disclosing an influencer’s postings with “#ad” increases the trustworthiness of the influencer and the general credibility of the posting for heavy users, but not for light users. Followership of a user has been found to strongly improve all researched variables (attitude toward product placement, trustworthiness of the spokesperson and general credibility of the posting). This study adds to literature the first distinction on heavy and light usage intensity, and on followership of an IG user when regarding the effects of advertisement disclosure types on advertising performance. To conclude, we present a number of recommendations regarding how advertisers, influencers, and SNS providers should develop strategies for monitoring, understanding, and responding to different social media users, e.g., to closely monitor an influencer’s audience to identify heavy users and optimally target them.

Published: May 2022

Abstract
Background
Patients with advanced salivary gland malignancies (SGCs) have few therapy options. Although results from newly published trials suggest that checkpoint inhibition may be useful in a subgroup of patients, there are no clear criteria for PD-L1 score in SGCs. Chemotherapy benefits were observed to be limited, with a dismal prognosis in unresectable and high-grade SGC. Immunotherapies have demonstrated extraordinary efficacy in a variety of cancers, including non-small cell lung cancer and malignant melanoma. Anti-PD-1 antibody pembrolizumab has been shown to have potent anti-tumor action in a number of clinical trials.

Case presentation
We report a unique case of advanced high grade mucoepidermoid carcinoma of the parotid salivary gland after Pembrolizumab treatment as a first line therapy. The tumor was downstaged as a result of the pembrolizumab treatment, allowing for a successful surgical excision with no facial nerve sacrifice and no major neoadjuvant treatment adverse effects, and the final specimen pathology was tumor-free. In these types of malignancies, a similar technique resulted in a complete response (CR) radiologically and pathologically has never been discussed before.

Conclusions
In pretreated patients with high-grade salivary gland mucoepidermoid carcinoma, pembrolizumab showed good anticancer activity and provided a clinically, radiologically, and pathological response with a viable treatment choice. More research is needed to bring Pembrolizumab to the front-line of treatment. The time and duration of medication should be compared to the time required for surgery in these investigations.
A new mechanism for friction-induced vibration and noise
Authors: Chen Fang , Ouyang Huajiang , Wang Xiaocui 
Published: May 2022

AbstractFor years, friction-induced vibration and noise (FIVN) has puzzled many researchers in academia and industry. Several mechanisms have been proposed for explaining its occurrence and quantifying its frequencies, notably for automotive brake squeal, clutch squeal, and even rail corrugation. However, due to the complex and complicated nature of FIVN, there is not yet one fundamental mechanism that can explain all phenomena of FIVN. Based on experimental results obtained on a simple test structure and corresponding numerical validation using both complex eigenvalue analysis (CEA) and transient dynamic analysis (TDA), this study attempts to propose a new fundamental mechanism for FIVN, which is the repeated cycles of partial detachment and then reattachment of the contact surfaces. Since friction is ubiquitous and FIVN is very common, the insight into FIVN reported in this paper is highly significant and will help establish effective means to control FIVN in engineering and daily life.

AbstractThe paper describesanywayin the Irish component of the International Corpus of International English (ICE-IRL) and similarities and differences in its use compared with other varieties of English represented in the ICE-Corpus. The findings showed thatanywaywas most frequent in ICE-IRL closely followed by the Canadian component of the ICE-Corpus. It was least frequent in the Santa Barbara Corpus of Spoken American English. The present analysis has demonstrated thatanywayin Irish English has a distinctive pragmatic profile which is based on its position in the peripheries and what it is doing there.Anywayin the left periphery was placed after an intrusive topic, a digression, a correction, interruption by the hearer and permits the speaker to resume the topic in an explicit way. In Irish Englishanywayin the right periphery was above all an attenuating politeness marker.Anywaywas found with a hedging meaning in contexts where it restricted the validity of a proposition by making a correction or adjustment of some kind. The high frequency ofanywayin the right periphery as a hedging pragmatic marker can be analysed in terms of its capacity to index a special kind of Irishness characterized by the absence of self-promotion and avoidance of social distance

Professional Help-Seeking in Men Experiencing Sexual Problems – The Role of Sexual Identity and Minority Stress
Authors: Grabski Bartosz , Kasparek Krzysztof , Koziara Karolina , Mijas Magdalena 
Published: May 2022

ABSTRACT

Background
Only a minority of men experiencing sexual problems will seek professional help and the proportion of gay or bisexual men can be even lower.

Aim
To investigate if sexual identity and minority stress are related to professional help-seeking in Polish gay and bisexual men.

Methods
Sexual identity was measured with the standard question: “Do you consider yourself to be heterosexual, gay, or bisexual?” Men who provided a complete set of answers to the study tools and replied “yes” to the question: “Have you ever had a problem with sexual functioning that lasted at least several months?” were included (Ntotal =644, Nstraight = 203, Ngay = 324, Nbi = 117). A simple question on help-seeking was: “Did you seek professional assistance then?” Other data were gathered with the use of a self-constructed questionnaire. Minority stress processes, that is, internalized homophobia, expectations of rejection, and identity concealment, were measured with the subscales of the Sexual Minority Stress Scale.
Bivariate analyses and multivariate logistic regressions were performed to test the statistical significance of sexual identity and minority stress processes as predictors of professional help-seeking.

Outcomes
Contacting a specialist when experiencing a sexual problem.

Results
A total of 84.5% of all men did not seek professional help. Gay identity (OR = 0.58, P = .045), as opposed to bisexual identity, was significantly related to reduced odds of consulting a specialist. Age (OR = 1.03, P = .005), number of doctor’s visits per year (OR = 1.51, P &lt; .001), and a psychiatric diagnosis (OR = 1.65, P = .043) were positively related to help-seeking behaviors. Identity concealment significantly decreased the likelihood of consulting a specialist (OR = 0.94, P = .017).

Clinical Translation
Specialists need to be aware that gay identity and identity concealment may prevent a proportion of men from seeking their help and thus should be publicly explicit about their inclusive and nonpathologizing approach to sexual diversity.

Strengths and Limitations
The major strengths of the study include the use of a relatively large sample size and data from the little recognized Polish context characterized by a predominantly hostile anti-LGBT social climate, and exploration of a neglected topic of substantial significance at the public and individual levels. The major limitations are the use of nonprobability sampling, cross-sectional self-report design, and a single question to capture the presence of sexual problems with no measurement of associated distress.

Conclusion
Gay men are at risk of avoiding help-seeking when experiencing sexual problems because of identity concealment.
Inter-academic cooperation in the Arctic during the 1898–1901 Swedish–Russian Arc-of-Meridian expedition: Based on materials from the Russian Academy of Sciences Archives

Published: May 2022

Abstract
The article analyses the experience of international scientific cooperation in the Arctic in organising and conducting an academic Swedish–Russian Arc-of-Meridian expedition to the Spitsbergen archipelago in 1898–1901. This was one of the largest projects of its kind in history. The military and naval government agencies of the two countries were extremely interested in measuring the meridian arc near the Geographic North Pole. The fulfilment of this task made it possible to more accurately determine the shape of the Earth as a geoid. This was the significant and fundamental result of testing the hypothesis of the Newton–Huygens spheroid and was of applied importance. Funding for the expeditionary activities was carried out on a parity basis from the budgets of the two nations. The study of archival documents from the collections of the Russian Academy of Sciences Archives enabled an understanding of the unprecedented financial and physical costs of preparing and carrying out expeditionary work. Analysing inter-academic research of the late nineteenth – early twentieth centuries is valuable for understanding the potential interactions between the government and academic structures of international scientific cooperation in the Arctic during the modern era.
Quantifying and Reducing Uncertainty in Global Carbon Cycle Predictions: Lessons and Perspectives From 15 Years of Data Assimilation Studies With the ORCHIDEE Terrestrial Biosphere Model

AbstractPredicting terrestrial carbon, C, budgets and carbon‐climate feedbacks strongly relies on our ability to accurately model interactions between vegetation, C and water cycles, and the atmosphere. However, C fluxes simulated by global, process‐based terrestrial biosphere models (TBMs) remain subject to large uncertainties, partly due to unknown or poorly calibrated parameters. This is because TBMs have not routinely been confronted against C cycle related datasets within a statistical data assimilation (DA) system. In this review, we present 15 years' development of a C cycle DA system for optimizing C cycle parameters of the ORCHIDEE TBM. We analyze the impact of assimilating multiple different C cycle related datasets on regional to global‐scale gross and net CO2 fluxes. We find that assimilating atmospheric CO2 data is crucial for improving (increasing) ORCHIDEE predictions of the terrestrial land C sink. The improvement is predominantly due to the global‐scale constraint these data provide for optimizing initial soil C stocks, which are likely in error due to inaccurate assumptions about steady state spin‐up and incomplete knowledge of land use change histories. When comparing the data‐constrained ORCHIDEE land C sink estimates to the CAMS atmospheric inversion, we show that while the two approaches agree on the global C sink magnitude, they continue to differ in how the global C sink is partitioned between the northern hemisphere and tropics. We also discuss technical challenges faced in our C cycle DA studies, in particular the difficulty in characterizing the error covariance matrix due to unknown observation biases and/or model‐data inconsistencies. We offer our perspectives on how to tackle these challenges that we hope can serve as a roadmap for other TBM groups wishing to develop C cycle DA systems.
Optimal Precursor Triggering Kuroshio Large Meander Decay Obtained in a Regional Ocean Model
Authors: Liu Xia , Wang Qiang , Zhang Hui 
Published: May 2022

AbstractThis study investigates the optimal precursor (OPR) triggering Kuroshio large meander (LM) decay using a conditional nonlinear optimal perturbation (CNOP) approach and a regional ocean modeling system (ROMS). The results show that the large amplitudes of the OPR are mainly concentrated at 1,000–2,500 m in the LM upstream region (west of 137°E), and their propagation downstream along the Kuroshio axis contributes to triggering the transition from the LM path to the nonlarge meander (NLM) path. Using the growth of the OPR, it is found that baroclinic instability contributes to the fast vertical development of the perturbations in the early stage of the LM decay, while barotropic processes play a leading role during the cyclonic ring shedding of the LM decay. In particular, the LM decay process is evaluated by the depth‐integrated vorticity equation, implying that the advection term dominates over the beta effect in the LM decay. Furthermore, the vorticity balance associated with the cyclonic eddy indicates that the advection and divergence terms represent a main balance in the spin‐down process of the cyclonic eddy. Under the effects of both, high potential vorticity water flows out from the LM meander tip and then the amplitude of the LM experiences a remarkable decrease. With the detachment of a cyclonic ring, a transition from the LM path to the NLM path occurs. This study further deepens our understanding of the LM decay and provides us some useful hints about designing the observation system of the LM.

AbstractThe hydroclimate of the Tibetan Plateau (TP) and Central Asia (CA) plays a crucial role in sustaining surface water reservoirs and thus water resources in the respective regions. In this study, we investigate the changes in Asian hydroclimate and its driving forces during specific time intervals in the last 3 Ma. We conduct high‐resolution (∼0.75° per grid cell) general circulation model ECHAM‐5 experiments with boundary conditions for the mid‐Pliocene (∼3 Ma), the Last Glacial Maximum (LGM; ∼21 ka), the mid‐Holocene (∼6 ka), and the pre‐industrial. Results suggest that seasonally relatively high precipitation rates (>1 mm day−1) were longer in the mid‐Pliocene and shorter in the LGM, relative to the pre‐industrial. We calculate different monsoon indices to detect changes in the intensity, strength and duration of the East Asian summer monsoon (EASM), South Asian summer monsoon (SASM), and the Indian summer monsoon (ISM), and construct climatologies of mid‐latitude high‐level westerly jet (WJ) stream occurrences based on the ECHAM5 wind fields. Our results suggest that in warm periods (e.g., mid‐Pliocene or interglacial), the WJ migrates northward earlier in the year (April) and reaches higher latitudes than in the pre‐industrial, resulting in a wetter TP and CA. During cooler periods (e.g., LGM or glacial), the WJ migrates northward later in the year (June) and remains over lower latitudes, resulting in a drier TP and CA. Increased/decreased local precipitation in TP and CA for the mid‐Pliocene/LGM experiments correlates strongly with (a) intensity, strength and duration of the EASM, SASM, and the ISM and (b) WJ latitudinal position.
Selective Csp3–F Bond Functionalization with Lithium Iodide

Published: May 2022

AbstractA highly efficient method for C–F bond functionalization of a broad variety of activated and unactivated aliphatic substrates with inexpensive lithium iodide is presented. Primary, secondary, tertiary, benzylic, propargylic and α-functionalized alkyl fluorides react in chlorinated or aromatic solvents at room temperature or upon heating to give the corresponding iodides, which are isolated in 91–99% yield. The reaction is selective for aliphatic monofluorides and can be coupled with in situ nucleophilic iodide replacements to install carbon–carbon, carbon–nitrogen, and carbon–sulfur bonds with high yields. Alkyl difluorides, trifluorides, even in activated benzylic positions, are inert under the same conditions and aryl fluoride bonds are also tolerated.

Published: May 2022

We describe a merged beams experiment to study ion-neutral collisions at the Cryogenic Storage Ring of the Max Planck Institute for Nuclear Physics in Heidelberg, Germany. We produce fast beams of neutral atoms in their ground term at kinetic energies between 10 and 300 keV by laser photodetachment of negative ions. The neutral atoms are injected along one of the straight sections of the storage ring, where they can react with stored molecular ions. Several dedicated detectors have been installed to detect charged reaction products of various product-to-reactant mass ranges. The relative collision energy can be tuned by changing the kinetic energy of the neutral beam in an independent drift tube. We give a detailed description of the setup and its capabilities, and present proof-of-principle measurements on the reaction of neutral C atoms with D2+ ions.
Eccentric self-forced inspirals into a rotating black hole
Authors: Lynch Philip , van de Meent Maarten , Warburton Niels 
Published: May 2022

Abstract
We develop the first model for extreme mass-ratio inspirals (EMRIs) into a rotating massive black hole driven by the gravitational self-force (GSF). Our model is based on an action angle formulation of the method of osculating geodesics for eccentric, equatorial (i.e., spin-aligned) motion in Kerr spacetime. The forcing terms are provided by an efficient spectral interpolation of the first-order GSF in the outgoing radiation gauge. We apply a near-identity (averaging) transformation to eliminate all dependence of the orbital phases from the equations of motion, while maintaining all secular effects of the first-order GSF at post-adiabatic order. This implies that the model can be evolved without having to resolve all

orbit cycles of an EMRI, yielding an inspiral model that can be evaluated in less than a second for any mass-ratio. In the case of a non-rotating central black hole, we compare inspirals evolved using self-force data computed in the Lorenz and radiation gauges. We find that the two gauges generally produce differing inspirals with a deviation of comparable magnitude to the conservative self-force correction. This emphasizes the need for including the (currently unknown) dissipative second order self-force to obtain gauge independent, post-adiabatic waveforms.
