The piercing–stretching suture technique for the treatment of simple oral floor ranula
Authors: Gaffuri M , Torretta S , Pignataro L , Capaccio P 
Published: October 2021

AbstractBackgroundOral floor ranulas are pseudocysts located in the floor of the mouth that result from the extravasation of mucus from a sublingual gland. Historically, there has been little consensus on the ideal first-line treatment. Currently, definitive treatment involves sublingual gland excision, which can injure the lingual nerve and submandibular duct. Minimally invasive surgical techniques have been proposed, but so far have been associated with a high rate of recurrence.MethodsThe so-called piercing–stretching suture technique was performed in 14 naïve adult and paediatric patients (6 females, with a mean age of 20.3 years (range, 7–55 years)). Clinical and ultrasonographic evaluations were performed in all patients; post-operative sialendoscopy was conducted in two paediatric patients.ResultsThe surgical procedure was successful in all patients, and complete recovery of the ranula was seen in all but one of the patients who underwent suture replacement. No major or minor complications were encountered.ConclusionThis minimally invasive procedure may be considered a reliable and first-line treatment for management of simple oral floor ranulas.

Published: October 2021

AbstractWe derive an extensive catalog of low‐frequency earthquakes (LFEs) in western and central Shikoku applying an automatic, coherency‐based detection and location method to 4‐year long continuous data from selected seismic stations. Our catalog is the first LFE catalog in this area that does not rely on a priory templates and results from a homogeneous data processing scheme. It allows investigating in detail main characteristics of LFE activity in space and time. We observe clear heterogeneity of the LFE space distribution in the along‐strike direction of the subducting Philippine Sea plate corresponding to segments with different sizes, some of which are highly productive in LFE generation. More detailed statistical and correlation‐based analysis of LFE occurrence patterns allows quantification of the along‐strike segmentation and examination of the migration and event interaction during the LFE sequences and inter‐sequence periods. The analysis indicates that a strong interaction exists among LFE sources during slow slip events, but it otherwise varies significantly among the along‐strike segments. We suggest that the observed segmentation of LFE activity is related to static heterogeneity, such as structural property variations along the subduction interface, or dynamic heterogeneity, corresponding to memory‐dependent stress variations or possible fluid transients. We also confirm that regions with the highest LFE productivity correspond to spots of tectonic tremor triggered by teleseismic earthquakes' surface waves supporting a localized fluid‐rich environment with possible fluid transients. Our results illustrate how high‐resolution LFE catalog can contribute to the characterization and quantification of slow earthquake processes through detailed statistical analysis of their activity.
Response of Northern North Atlantic and Atlantic Meridional Overturning Circulation to Reduced and Enhanced Wind Stress Forcing

AbstractSurface wind stress strongly influences Atlantic meridional overturning circulation (AMOC) variability on interannual time scales. On longer time scales, however, its role in AMOC variations is less clear. Here, we show a nonlinear AMOC response to globally reduced and enhanced wind stress forcing, based on sensitivity experiments with MPI‐ESM1.2. Under reduced wind stress forcing, the AMOC strength strongly decreases. In contrast, under enhanced wind stress forcing the AMOC strength increases only in the first decades and then decreases, stabilizing at a value similar to the reference simulation. To reveal possible mechanisms underlying this response, we assess the response of the northern North Atlantic circulation and climate to the changed wind stress forcing. Initially, the response is linear: reduced wind stress forcing weakens the gyre circulation and the associated heat and salt transport, leading to larger winter sea ice extent and a shutdown of subpolar deep convection. In the Nordic Seas, the fresher and lighter subsurface state leads to a decrease in the baroclinic pressure and the overflow strength. Under enhanced wind stress forcing, initially, the opposite is happening. However, eventually, subpolar surface density anomalies are determined by warmer temperature rather than increased salinity, leading to a decrease in surface density and a weakening of subpolar deep convection. The resulting AMOC weakening reduces the Atlantic inflow salinity, and subsequently the Nordic Seas baroclinic pressure and overflow strength. The quasi‐equilibrium response of the northern North Atlantic circulation and climate under enhanced wind stress forcing differs from the reference simulation, even though the AMOC strength converges.
Characterizing Multitasking and Workflow Fragmentation in Electronic Health Records among Emergency Department Clinicians: Using Time-Motion Data to Understand Documentation Burden

Published: October 2021

Abstract
Background The impact of electronic health records (EHRs) in the emergency department (ED) remains mixed. Dynamic and unpredictable, the ED is highly vulnerable to workflow interruptions.
Objectives The aim of the study is to understand multitasking and task fragmentation in the clinical workflow among ED clinicians using clinical information systems (CIS) through time-motion study (TMS) data, and inform their applications to more robust and generalizable measures of CIS-related documentation burden.
Methods Using TMS data collected among 15 clinicians in the ED, we investigated the role of documentation burden, multitasking (i.e., performing physical and communication tasks concurrently), and workflow fragmentation in the ED. We focused on CIS-related tasks, including EHRs.
Results We captured 5,061 tasks and 877 communications in 741 locations within the ED. Of the 58.7 total hours observed, 44.7% were spent on CIS-related tasks; nearly all CIS-related tasks focused on data-viewing and data-entering. Over one-fifth of CIS-related task time was spent on multitasking. The mean average duration among multitasked CIS-related tasks was shorter than non-multitasked CIS-related tasks (20.7 s vs. 30.1 s). Clinicians experienced 1.4 ± 0.9 task switches/min, which increased by one-third when multitasking. Although multitasking was associated with a significant increase in the average duration among data-entering tasks, there was no significant effect on data-viewing tasks. When engaged in CIS-related task switches, clinicians were more likely to return to the same CIS-related task at higher proportions while multitasking versus not multitasking.
Conclusion Multitasking and workflow fragmentation may play a significant role in EHR documentation among ED clinicians, particularly among data-entering tasks. Understanding where and when multitasking and workflow fragmentation occurs is a crucial step to assessing potentially burdensome clinician tasks and mitigating risks to patient safety. These findings may guide future research on developing more scalable and generalizable measures of CIS-related documentation burden that do not necessitate direct observation techniques (e.g., EHR log files).
On the isochronous center of planar piecewise polynomial potential systems

This paper is devoted to the isochronicity of two kinds of planar piecewise polynomial potential systems separated by

-axis and

y
y

-axis, respectively. By means of the expansion of the period function near the infinity, we obtain in this paper that for these two cases, the piecewise potential system has an isochronous center at the origin if and only if the subsystems are linear. It is however not true in the analytic scenario; one can find in the paper by F. Mañosas and P. J. Torres [Proc. Amer. Math. Soc. 133 (2005), pp. 3027–3035] that the isochronicity of the center of the piecewise analytic potential system cannot imply the linearity of the two subsystems.
Roots and rootlessness
Authors: Ratner-Rosenhagen Jennifer 
Published: October 2021

Abstract
‘Roots and rootlessness’ examines the period from the end of World War I to the end of World War II, which was marked by intellectual daring and profound antimodernism. The Roaring Twenties yielded new insights into human nature and experiments in modernist poetry, art, and literature. The decade also witnessed fears about loose sexual mores, racial mongrelization, and deicide. In the aftermath of victory in World War I, American thinkers from diverse backgrounds and viewpoints participated in a common project of finding new terms and modes of expression for understanding America. They examined America’s unfinished revolution for freedom and equality and provided new inspiration for finding unity in its diversity.
Epilogue

Published: October 2021

Abstract
‘Epilogue’ traces the turn-of-the-twenty-first century interest in globalization and its implication for addressing intellectual problems in the United States. The perils and possibilities of globalization for American life vexed thinkers on how globalization intensified nationalism around the world. Globalization was a new framework and scale for long-standing and familiar ways of thinking about the boundaries of moral communities. It also refashioned identities in the face of a diverse world and uncertain future.
Jewish and Christian readings of the Binding of Isaac
Authors: Riches John 
Published: October 2021

Abstract
‘Jewish and Christian readings of the Binding of Isaac’ assesses some of the readings of the Bible by believers, both Jews and Christians. It focuses on the Akedah, the story of Abraham’s binding of Isaac in Genesis 22. The Akedah is a story of strange violence and tenderness, of a father ordered by his God to sacrifice ‘his only son’. For Jews, this is a story read in the light of the history of Jewish persecution. Remarkable retellings of the story are to be found from Rabbis in the Rhineland during the Crusades. For Christians, the themes of the Akedah are largely subsumed in their reading of the Passion. Nevertheless, the story has continued to exert its spell, remaining a story which raises profound questions about the nature of faith and suffering. Its use by philosophers (Kierkegaard) and poets (Wilfred Owen) is examined.

AbstractUganda continues extensive mobilization and administration of the Covid 19 vaccine to its people albeit some vaccine hesitancy with in the population. Amongst the health workers however, approximately 70% had received their first dose while 40% had received their second dose of the Covid-19 vaccine by September 2021 respectively. These figures represent a recognizable acceptance rate among health workers. Exploring motivators to vaccine uptake among health workers is vital for the government’s general population vaccine rollout plan.We conducted 12 focus group discussions and 20 in-depth interviews with health workers (vaccinated and unvaccinated) to understand motivators to vaccine acceptance in their own perspective in central and eastern Uganda. Reported motivators to vaccine acceptance included; risk susceptibility/protection, fear of death and/or cost of treatment and experiences of Covid related grief. Other were trust in the vaccine, call to government policy and vaccine success stories elsewhere, real or perceived benefits of vaccination and peer influence.We recommend intensified dissemination of health worker tailor made tools/guides for information, education and communication about the Covid 19 vaccine. The tools need to emphasize the elicited themes/motivators. We also recommend use of peers who have taken up the vaccine and survived Covid-19 or got a mild form of the disease to elicit positive peer influence about the vaccine amongst health workers. The information dissemination and peer narratives could be done through the health worker’s social media platforms, union or association websites, personal statements, editorials or other media.

AbstractBackgroundPlacental malaria (PM) is associated with a higher susceptibility of infants to Plasmodium falciparum (Pf) malaria. A hypothesis of immune tolerance has been suggested but no clear explanation has been provided so far. Our goal was to investigate the involvement of inhibitory receptors LILRB1 and LILRB2, known to drive immune evasion upon ligation with pathogen and/or host ligands, in PM-induced immune tolerance.MethodsInfants of mothers with or without PM were enrolled in Allada, southern Benin, and followed-up for 24 months. Antibodies with specificity for five blood stage parasite antigens were quantified by ELISA, and the frequency of immune cell subsets was quantified by flow cytometry. LILRB1 or LILRB2 expression was assessed on cells collected at 18 and 24 months of age.ResultsInfants born to PM-mothers had a higher risk of developing clinical malaria than those born to mothers without PM (IRR=1.53, p=0.040), and such infants displayed a lower frequency of non-classical monocytes (OR=0.74, p=0.01) that overexpressed LILRB2 (OR=1.36, p=0.002). Moreover, infants born to PM-mothers had lower levels of cytophilic IgG and higher levels of IL-10 during active infection.ConclusionModulation of IgG and IL-10 levels could impair monocyte functions (opsonisation/phagocytosis) in infants born to PM-mothers, possibly contributing to their higher susceptibility to malaria. The long-lasting effect of PM on infants’ monocytes was notable, raising questions about the capacity of ligands such as Rifins or HLA-I molecules to bind to LILRB1 and LILRB2 and to modulate immune responses, and about the reprogramming of neonatal monocytes/macrophages.KEY POINTSInfants of mothers with placental malaria were more susceptible to clinical malaria than those born to mothers without placental malaria and they displayed a lower frequency of non-classical monocytes that overexpressed LILRB2.
Robot obstacle avoidance system using deep reinforcement learning
Authors: Zhu Xiaojun , Liang Yinghao , Sun Hanxu , Wang Xueqian , Ren Bin 
Published: October 2021

Purpose
Most manufacturing plants choose the easy way of completely separating human operators from robots to prevent accidents, but as a result, it dramatically affects the overall quality and speed that is expected from human–robot collaboration. It is not an easy task to ensure human safety when he/she has entered a robot’s workspace, and the unstructured nature of those working environments makes it even harder. The purpose of this paper is to propose a real-time robot collision avoidance method to alleviate this problem.

Design/methodology/approach
In this paper, a model is trained to learn the direct control commands from the raw depth images through self-supervised reinforcement learning algorithm. To reduce the effect of sample inefficiency and safety during initial training, a virtual reality platform is used to simulate a natural working environment and generate obstacle avoidance data for training. To ensure a smooth transfer to a real robot, the automatic domain randomization technique is used to generate randomly distributed environmental parameters through the obstacle avoidance simulation of virtual robots in the virtual environment, contributing to better performance in the natural environment.

Findings
The method has been tested in both simulations with a real UR3 robot for several practical applications. The results of this paper indicate that the proposed approach can effectively make the robot safety-aware and learn how to divert its trajectory to avoid accidents with humans within the workspace.

Research limitations/implications
The method has been tested in both simulations with a real UR3 robot in several practical applications. The results indicate that the proposed approach can effectively make the robot be aware of safety and learn how to change its trajectory to avoid accidents with persons within the workspace.

Originality/value
This paper provides a novel collision avoidance framework that allows robots to work alongside human operators in unstructured and complex environments. The method uses end-to-end policy training to directly extract the optimal path from the visual inputs for the scene.
Cyclic deformation behavior of Mg–SiC nanocomposites on the macroscale and nanoscale

Published: October 2021

AbstractMetal‐ceramic nanocomposites are promising candidates for applications necessitating light weight and excellent fatigue resistance. We produced Mg–SiC nanocomposites from mechanically milled powders, yielding a homogeneous nanocrystalline structure and excellent quasistatic strength values. Little is known, however, about the fatigue behavior of such composites. Here, we used load increase tests on the macroscale to yield estimation values of the fatigue endurance limit. Fatigue strength increased significantly for the materials processed by the powder metallurgical route. We further investigated the cyclic deformation behavior under stress‐controlled conditions on the macroscale and nanoscale. Cyclic nanoindentation showed that indentation depth and cyclic plastic deformation decreased with increasing reinforcement content, hinting to a higher cyclic strength and corroborating the results from the macroscopic load increase tests. Our results therefore show that cyclic nanoindentation reliably determines the plastic deformation behavior of Mg nanocomposites offering the possibility of fast material analysis.
Luteal expression of factors involved in the metabolism and sensitivity to oestrogens in the dog during pregnancy and in non‐pregnant cycle

Published: October 2021

AbstractThe canine corpus luteum (CL) is the main source of reproductive steroids during dioestrus in the dog and remains active even in the absence of pregnancy (non‐pregnant dioestrus, physiological pseudopregnancy). Whereas the biological effects of 17β‐oestradiol (E2) in the canine CL remain unclear, the transcriptional availability of oestrogen receptors, ESR1 and ESR2, as well as other modulators of local availability of E2, for example, HSD17B7 (converts oestrone into oestradiol), SULT1E1 (inactivates E2 binding capacity to its own receptors through sulphonation) and STS (reverts E2 sulphonation), were previously detected in the CL of non‐pregnant bitches. The aim of the present work was to evaluate the mRNA amounts of these factors involved in luteal sensitivity and metabolism of E2 in the canine CL during the course of non‐pregnant dioestrus (days 10, 20, 30, 40, 50 and 60 post‐ovulation, n = 5/group) and at different stages of pregnancy (n = 4‐6/group): pre‐implantation (days 8–12), post‐implantation (days 18–25), mid‐gestation (days 35–40) and prepartum luteolysis. During pregnancy, the availability of ESR1, HSD17B7, SULT1E1 and STS decreased from mid‐pregnancy to prepartum luteolysis. The main findings during non‐pregnant dioestrus were as follows: increased ESR2:ESR1 ratio on days 40 and 50 after ovulation, decreasing during luteal regression (day 60); increased STS at day 30 when SULT1E1 levels decreased; increased availability of SULT1E1 transcripts during luteal regression; and decreased amounts of HSD17B7 mRNA in early dioestrus, increasing towards later stages. These results suggest that E2 signalling and biologically active local concentrations could diverge in response to time and pregnancy status of the bitch.
