Abstract
Background
Superior mesenteric artery plexus (SMAP) injury is reported to cause postoperative intractable diarrhea after pancreatic/colonic surgery with extended lymphadenectomy. This study aims to describe the SMAP microanatomy and extent of injury after right colectomy with extended D3 mesenterectomy for cancer.

Methods
Three groups (I) anatomical dissection, (II) postmortem histology, and (III) surgical specimen histology were included. Nerve count and area were compared between groups II and III and paravascular sheath thickness between groups I and II. 3D models were generated through 3D histology, nanoCT scanning, and finally through 3D printing.

Results
A total of 21 specimens were included as follows: Group (I): 5 (3 females, 80–93 years), the SMAP is a complex mesh surrounding the superior mesenteric artery (SMA), branching out, following peripheral arteries and intertwining between them, (II): 7 (5 females, 71–86 years), nerve count: 53 ± 12.42 (38–68), and area: 1.84 ± 0.50 mm2 (1.16–2.29), and (III): 9 (5 females, 55–69 years), nerve count: 31.6 ± 6.74 (range 23–43), and area: 0.889 ± 0.45 mm2 (range 0.479–1.668). SMAP transection injury is 59% of nerve count and 48% of nerve area at middle colic artery origin level. The median values of paravascular sheath thickness decreased caudally from 2.05 to 1.04 mm (anatomical dissection) and from 2.65 to 1.17 mm (postmortem histology). 3D histology models present nerve fibers exclusively within the paravascular sheath, and lymph nodes were observed only outside. NanoCT-derived models reveal oblique nerve fiber trajectories with inclinations between 35° and 55°. Two 3D-printed models of the SMAP were also achieved in a 1:2 scale.

Conclusion
SMAP surrounds the SMA and branches within the paravascular sheath, while bowel lymph nodes and vessels lie outside. Extent of SMAP injury on histological slides (transection only) was 48% nerve area and 59% nerve count. The 35°–55° inclination range of SMAP nerves possibly imply an even larger injury when plexus excision is performed (lymphadenectomy). Reasons for later improvement of bowel function in these patients can lie in the interarterial nerve fibers between SMA branches.
An extension of a theorem of Bers and Finn on the removability of isolated singularities to the Euler–Lagrange equations related to general linear growth problems
Authors: Bildhauer Michael , Fuchs Martin 
Published: April 2022

AbstractA famous theorem of Bers and Finn states that isolated singularities of solutions to the non-parametric minimal surface equation are removable. We show that this result remains valid, if the area functional is replaced by a general functional of linear growth depending on the modulus of the gradient.

AbstractNutrient inputs to northern freshwaters are changing, potentially altering aquatic ecosystem functioning through effects on primary producers. Yet, while primary producer growth is sensitive to nutrient supply, it is also constrained by a suite of other factors, including light and temperature, which may play varying roles across stream and lake habitats. Here, we use bioassay results from 89 lakes and streams spanning northern boreal to Arctic Sweden to test for differences in nutrient limitation status of algal biomass along gradients in colored dissolved organic carbon (DOC), water temperature, and nutrient concentrations, and to ask whether there are distinct patterns and drivers between habitats. Single nitrogen (N) limitation or primary N-limitation with secondary phosphorus (P) limitation of algal biomass was the most common condition for streams and lakes. Average response to N-addition was a doubling in biomass; however, the degree of limitation was modulated by the distinct physical and chemical conditions in lakes versus streams and across boreal to Arctic regions. Overall, algal responses to N-addition were strongest at sites with low background concentrations of dissolved inorganic N. Low temperatures constrained biomass responses to added nutrients in lakes but had weaker effects on responses in streams. Further, DOC mediated the response of algal biomass to nutrient addition differently among lakes and streams. Stream responses were dampened at higher DOC, whereas lake responses to nutrient addition increased from low to moderate DOC but were depressed at high DOC. Our results suggest that future changes in nutrient availability, particularly N, will exert strong effects on the trophic state of northern freshwaters. However, we highlight important differences in the physical and chemical factors that shape algal responses to nutrient availability in different parts of aquatic networks, which will ultimately affect the integrated response of northern aquatic systems to ongoing environmental changes.

AbstractA pandemic poses particular challenges to decision-making because of the need to continuously adapt decisions to rapidly changing evidence and available data. For example, which countermeasures are appropriate at a particular stage of the pandemic? How can the severity of the pandemic be measured? What is the effect of vaccination in the population and which groups should be vaccinated first? The process of decision-making starts with data collection and modeling and continues to the dissemination of results and the subsequent decisions taken. The goal of this paper is to give an overview of this process and to provide recommendations for the different steps from a statistical perspective. In particular, we discuss a range of modeling techniques including mathematical, statistical and decision-analytic models along with their applications in the COVID-19 context. With this overview, we aim to foster the understanding of the goals of these modeling approaches and the specific data requirements that are essential for the interpretation of results and for successful interdisciplinary collaborations. A special focus is on the role played by data in these different models, and we incorporate into the discussion the importance of statistical literacy and of effective dissemination and communication of findings.
Are subjective cognitive complaints associated with executive functions and mental health of older adults?
Authors: Fastame Maria Chiara 
Published: April 2022

AbstractSubjective cognitive complaints are used to detect detrimental age-related variations in cognitive efficiency before cognitive decline occurs in late adulthood. Despite this, there is controversial evidence on the relationship between the aforementioned metacognitive measure and the actual cognitive efficiency of older individuals. Instead, subjective cognitive complaints seem to be related to perceived mental health. This study aimed to investigate the nature of the relationships between subjective cognitive failures, mental health, and executive functioning. An additional goal was to examine whether there were significant differences in perceived mental health and executive functions efficiency by comparing older people who exhibited fewer subjective cognitive complaints with a group who reported more cognitive complaints. Eighty-nine community-dwellers (Mage = 78.6 years, SD = 6.5 years; age range = 66–95 years), 42 males and 47 females, were recruited and completed a battery of tools assessing cognitive failures, depressive symptoms, psychological well-being, optimism, global cognitive functioning, vocabulary, and several executive functions. Significant relationships were only found between self-reported cognitive failures, depressive symptoms, optimism, and psychological well-being. Moreover, participants who reported more cognitive failures also exhibited less optimism and psychological well-being and showed more depressive symptoms than older respondents who exhibited fewer cognitive complaints. Finally, no differences in the measures of executive functioning were found between groups exhibiting low vs. high levels of subjective cognitive complaints. In conclusion, the concurrent objective assessment of cognitive functioning and self-reported evaluation of cognitive processes and mental health of older people should be encouraged, to detect possible threats to their well-being.
Data-driven de-smearing of DSC signals
Authors: Sommer Andreas , Hohenauer Wolfgang , Barz Tilman 
Published: April 2022

AbstractIn heat flux differential scanning calorimetry, a pair of identical crucibles, one empty as reference and the other filled with the sample, is heated in a furnace with a prescribed rate. The (empty) reference crucible heats faster, resulting in a temperature difference that is detected by thermocouples. Slow heating of the furnace results in weak and noisy signals; higher heating rates induce strong signals but lead to smearing if applied to materials undergoing a phase transition: The recorded peak signal is shifted toward higher temperatures. To determine the peak, the onset/endset temperatures, and the phase transition enthalpy, multiple heating rates are used to find a trade-off between noise and smearing. When plotting the melting peaks over temperature and heating rate, the visual similarity to the time evolution of a probability density under drift and diffusion catches the eye. Such a density evolution can be described by the Fokker–Planck equations. In this analogon, the de-smeared signal corresponds to the initial distribution. We propose a data-driven de-smearing approach, based on an extrapolation to a (hypothetical) zero heating rate signal. This zero rate signal is low-dimensionally parameterized and its parameters together with the drift and diffusion of the Fokker–Planck equation are fitted against the calorimetric measurements. The method is successfully tested on heat capacity data of a technical-grade high-density polyethylene (HDPE) using mid-range heating rates. The data are strongly affected by smearing, and the proposed de-smearing method $${FPEX}_{0}$$

Quantum Byzantine Agreement for Any Number of Dishonest Parties
Authors: Cholvi Vicent 
Published: April 2022

AbstractReaching agreement in the presence of arbitrary faults is a fundamental problem in distributed computation, which has been shown to be unsolvable if one-third of the processes can fail, unless signed messages are used. In this paper, we propose a solution to a variation of the original BA problem, called Detectable Byzantine Agreement (DBA), that does not need to use signed messages. The proposed algorithm uses what we call Q-correlated lists, which are generated by a quantum source device. Once each process has one of these lists, they use them to reach the agreement in a classical manner. Although, in general, the agreement is reached by using $$m+1$$

rounds (where m is the number of processes that can fail), if less than one-third of the processes fail it only needs one round to reach the agreement.

Published: April 2022

AbstractIn this review we discuss all the relevant solar/stellar radiation and plasma parameters and processes that act together in the formation and modification of atmospheres and exospheres that consist of surface-related minerals. Magma ocean degassed silicate atmospheres or thin gaseous envelopes from planetary building blocks, airless bodies in the inner Solar System, and close-in magmatic rocky exoplanets such as CoRot-7b, HD 219134 b and 55 Cnc e are addressed. The depletion and fractionation of elements from planetary embryos, which act as the building blocks for proto-planets are also discussed. In this context the formation processes of the Moon and Mercury are briefly reviewed. The Lunar surface modification since its origin by micrometeoroids, plasma sputtering, plasma impingement as well as chemical surface alteration and the search of particles from the early Earth’s atmosphere that were collected by the Moon on its surface are also discussed. Finally, we address important questions on what can be learned from the study of Mercury’s environment and its solar wind interaction by MESSENGER and BepiColombo in comparison with the expected observations at exo-Mercurys by future space-observatories such as the JWST or ARIEL and ground-based telescopes and instruments like SPHERE and ESPRESSO on the VLT, and vice versa.

Ghost Brides and Crime Networks in Rural China
Authors: Lo T. Wing 
Published: April 2022

AbstractThe custom of ghost marriages has been passed down since the ancient times in China. Adults who died before marriage could not be buried with their ancestors. Their families did not want to leave bodies outside, as they believed that the spirits would become lonely. Instead, they wished to find husbands or wives for their dead relatives to continue the family tree. The custom has spawned a large ghost bride market, resulting in the trading of female corpses. This industry and its profits have driven criminals to kidnap and murder women, raid tombs and morgues, steal and traffic corpses. The study demonstrates that while in the folklore the stigma of being unmarried should apply to both men and women, the corpses trafficked are mainly women and in poorer provinces. While ghost marriages create a market of supply and demand in booming rural China, the market also indicates income and gender inequality behind the crime.
Comparative Public Policy Analysis: Shortcomings, Pitfalls, and Avenues for the Future
Authors: Wenzelburger Georg , Jensen Carsten 
Published: April 2022

AbstractComparative public policy is a blooming research area. It also suffers from some curious blind spots. In this paper we discuss four of these: (1) the obsession with covariance, which means that important phenomena are ignored; (2) the lack of agency, which leads to underwhelming explanatory models; (3) the unclear universe of cases, which means the inferential value of theories and the empirical results are unclear; and (4) the focus on outputs, even though most theories contain strong assumptions about the political process leading to certain outputs. Following this discussion, we then outline how a closer integration of policy process theories may be fruitful for future research.
Exploring the adoption and expression of subcultural identities among gay, bisexual, and queer-identifying men in Australia
Authors: Franklin Jake D. , Lyons Anthony , Bourne Adam 
Published: April 2022

AbstractGay, bisexual, and queer-identifying (GBQ) communities tend to comprise various subcultural identity groups based around shared practices and intersectional identities, but little research has sought to qualitatively understand how these identities are situated within communities and enacted in everyday life. Further understanding subcultural identities is important as they reflect the diversity of GBQ men and potential health risks/differences between groups of men that may otherwise not be considered. This study aimed to advance understanding of GBQ subcultural identities in Australia by investigating how GBQ men come to adopt and express subcultural identities, such as ‘Bear’, ‘Twink’, or ‘Daddy’. Fifteen gay, bisexual, and queer-identifying men living in Australia who identified with one or more GBQ subcultures participated in semi-structured in-depth interviews between September and November 2019. An inductive thematic analysis with semantic coding and a realist framework was used to assess patterns of meaning within the data. Two higher level themes emerged relating to discovering identity and evolving practices of identification, with sub-themes related to self-guided exploration, identification by others, and contextual changes in expressing identity. These findings highlight that adopting subcultural identities involved elements of exploring language and discourse and embracing or resisting identification. The ways in which subcultural identities were integrated and expressed appeared to evolve over time and shift within different contexts, including emphasising or suppressing aspects of identity. This knowledge expands understanding of GBQ subcultural identities and help inform culturally-sensitive considerations for health promotion, policy, and research that engages GBQ men.

AbstractEmotion dysregulation is a transdiagnostic factor in the development of various mental and behavioral disorders, thus requiring ample evidence for prevention and intervention approaches. The aim of the current systematic review and meta-analysis was to investigate the association between parenting dimensions/styles and emotion dysregulation in childhood and adolescence. Following the PRISMA guidelines, the review was registered (PROSPERO CRD42021251672) and search terms were entered in Web of Science, Scopus, PsycINFO, and PubMed in May 2021. Articles needed to report on empirical studies that examined the association between parenting dimensions/styles and emotion dysregulation in children/adolescents with primary data, and be published in English in a peer-reviewed journal. Additionally, articles were excluded based on certain designs and focus on special populations. The narrative synthesis includes 30 articles, and of which 27 are included in the meta-analysis. An NHLBI tool with 14 items (e.g., validity) was utilized for assessing the quality of the included studies. General trends indicate that positive parenting (e.g., warmth, supportiveness) is negatively associated with emotion dysregulation, whilst negative parenting (e.g., psychological control, authoritarian) is positively associated. The meta-analysis reveals an overall small yet significant effect, however, the heterogeneity of the studies is moderate to high. A funnel plot demonstrated no evidence of publication bias. Limitations include the varying conceptualizations of emotion dysregulation, as well as a lacking focus on specific types of emotion. Although more research is needed, addressing factors such as culture, gender, and age, the review provides first indications of the significance of parenting dimensions/styles for emotion dysregulation.
