Published: September 2023

AbstractRobust semantic segmentation of intraoperative image data could pave the way for automatic surgical scene understanding and autonomous robotic surgery. Geometric domain shifts, however – although common in real-world open surgeries due to variations in surgical procedures or situs occlusions – remain a topic largely unaddressed in the field. To address this gap in the literature, we (1) present the first analysis of state-of-the-art (SOA) semantic segmentation networks in the presence of geometric out-of-distribution (OOD) data, and (2) address generalizability with a dedicated augmentation technique termed ’Organ Transplantation’ that we adapted from the general computer vision community. According to a comprehensive validation on six different OOD data sets comprising 600 RGB and yperspectral imaging (HSI) cubes from 33 pigs semantically annotated with 19 classes, we demonstrate a large performance drop of SOA organ segmentation networks applied to geometric OOD data. Surprisingly, this holds true not only for conventional RGB data (drop of Dice similarity coefficient (DSC) by 46 %) but also for HSI data (drop by 45 %), despite the latter’s rich information content per pixel. Using our augmentation scheme improves on the SOA DSC by up to 67% (RGB) and 90% (HSI)) and renders performance on par with in-distribution performance on real OOD test data. The simplicity and effectiveness of our augmentation scheme makes it a valuable network-independent tool for addressing geometric domain shifts in semantic scene segmentation of intraoperative data.

Published: September 2023

AbstractComputational thinking (CT) is often defined as multifaceted which, on the one hand, allows researchers to embrace its complexity but, on the other hand, blurs the possibilities of its teaching. Although many models shed light on the multiple dimensions of CT, few studies investigate the benefits of combining such models when a teacher orchestrates in-class activities aiming at developing students’ CT. This position paper aims to fill this gap by describing and analysing how a teacher can base the orchestration of a pedagogical scenario on three different models: Komis et al.’s model to design ER activities in co-creative problem solving, Sentance et al.’s PRIMM model to scaffold the students’ tasks, and Chevalier et al.’s CCPS model to unscaffold the learning activities.
Mutation Breeding in Arabica Coffee
Authors: Ingelbrecht Ivan L. W. , Espinoza Noel Arrieta , Nielen Stephan , Jankowicz-Cieslak Joanna 
Published: September 2023

AbstractCoffee is a perennial (sub)tropical crop and one of the most valuable commodities globally. Coffee is grown by an estimated 25 million farmers, mostly smallholders, and provides livelihoods to about 125 million people. The Coffea genus comprises over 120 species. Two species account for nearly the entire world coffee production: C. arabica L. (Arabica coffee) and C. canephora Pierre ex A. Froehner (Canephora coffee) with the former supplying about 65% of the world’s consumption. Arabica coffee is a self-pollinated, amphidiploid species (2n = 4x = 44) whereas other Coffea species are diploid (2n = 2x = 22) and generally cross-pollinated. Induced mutagenesis using physical and chemical mutagens has been a successful strategy in producing over 3,300 mutant varieties in over 220 crop species with global impact. Spontaneous Arabica coffee mutants of significant economic importance have been found since the early 1900s, following the spread of Arabica coffee cultivation across the globe. However, Arabica coffee has so far not been improved through induced mutagenesis and studies on coffee mutagenesis are scarce. In this chapter, principles and practices of mutation-assisted breeding along with current breeding limitations of Arabica coffee are briefly reviewed, as an introduction to subsequent protocol chapters on mutation induction, advanced cell and tissue culture, Leaf Rust resistance screening and the application of novel molecular/genomics tools supporting mutation-assisted improvement and genetics research of Arabica coffee.

The Unsolved Mystery of the Gender Imbalance in IT
Authors: Corneliussen Hilde G. 
Published: September 2023

AbstractWomen are underrepresented in information technology (IT) education and work across the western world. This chapter contextualizes the topic of the book by revisiting research literature about girls’ and women’s participation in IT. Among the widely recognized barriers are gender stereotypes and gender structures in IT education and work. The chapter further reviews studies into motivational factors as well as research investigating women entering IT through non-traditional training grounds. Finally, the question of why the situation has not improved faster in the Nordic countries is discussed in light of the metaphor of a Nordic gender equality paradox. This reflects a gap between theory and practice and a myth of gender equality already in place that reduces efforts to address gender inequality in technology.
Girl Power: Reconstructing the Gendered Space of IT
Authors: Corneliussen Hilde G. 
Published: September 2023

AbstractThis chapter explores how women navigate and challenge gendered stereotypes defining IT as a masculine space. Most of the women had approached IT with limited insights. This made gender stereotypes, including a male-dominated storyline of gamers, geeks, and hackers, central to their early perceptions of the field. However, once they learnt more about IT, they started defining their own strengths and belonging in the field. The women’s experiences are analysed in light of Puwar’s metaphor of “space invaders”, highlighting how women appear as “bodies out of place” in a masculine space of IT. The space invader identity is also productive, and the women reconfigure the notion of IT as a wider and more open space where also women can be considered insiders.

Published: September 2023

AbstractPurposeTo compare patient‐reported pain scores and assess the influence of neuropathy and co‐morbidity, on knee pain following cemented and cementless medial unicompartmental knee replacement (UKR) 5 years after surgery.MethodIn this longitudinal study, 262 cemented and 262 cementless Oxford UKR performed for the same indications and with the same techniques were recruited. Patients were reviewed at five years, evaluating patient‐reported pain and association with clinical outcomes. Intermittent and Constant Osteoarthritis Pain (ICOAP), PainDETECT (PD), Charnley score, Oxford Knee Score (OKS) and American Knee Society Score (AKSS) were compared.ResultsIn both cohorts, intermittent pain was more common than constant pain (47% vs 21%). Cementless knees reported significantly less pain than cemented (ICOAP‐Total 5/100 vs 11/100, p < 0.0001). A greater proportion of cementless knees experienced no pain at all (ICOAP = 0/100, 61% vs 43%, p < 0.0001) and 75% fewer experienced severe or extreme pain. Pain sub‐scores in PD, OKS and AKSS follow this trend. Pain was unlikely to be neuropathic (PD positive: 5.26%), but patients reporting high levels of ‘strongest’ pain were three times more likely to be neuropathic. Patients with co‐morbidities (Charnley C) experienced greater pain than those without (Charnley A+B) across all knee‐specific scores, despite scores being knee specific.ConclusionBoth cemented and cementless UKR in this study had substantially less pain than that reported in literature following TKR. Cementless UKR had significantly less pain than cemented UKR in all scores. Two‐thirds of patients with a cementless UKR had no pain at all at 5 years, and pain experienced was most likely to be mild and intermittent with no patients in severe or extreme pain. Patients with cementless UKR that had higher levels of pain were more likely to have co‐morbidity or evidence or neuropathic pain. It is unclear why cementless UKR have less pain than cemented; further study is necessary.

Published: September 2023

Abstract
Introduction
Even though shoulder dislocation is thought to be the most common dislocation treated in the Emergency Department, inferior ones, known as Luxatio Erecta, comprise only 0.5% of them. Taking into consideration the rareness of unilateral Luxatio Erecta, bilateral cases should be even fewer.
The purpose of this paper is to identify the reported number of cases of Traumatic Bilateral Luxatio Erecta in the literature over the last 100 years and to summarize the mechanism of injury, the initial management, and the complications of these patients.

Materials and methods
We performed a systematic review of the literature regarding Traumatic Bilateral Luxatio Erecta. All articles published until 31st of December 2022 in PubMed and Google Scholar databases were searched using the terms “luxatio erecta”, ‘inferior dislocation”, and “bilateral”.

Results
Eighty-two articles were retrieved from PubMed and Google Scholar search. Forty-four of them were initially included in our review. Six additional articles meeting the inclusion criteria were found from cross-references.

Conclusion
The presence of this injury is extremely rare with only 51 cases in the literature. The incidence of concomitant injuries and complications seems to be extremely high and neurological deficits were detected on 42.8% of patients with Bilateral Luxatio Erecta. To our knowledge, this is the first systematic review of the literature regarding Traumatic Bilateral Luxatio Erecta that includes articles not only in English, a fact that provides more reliability on the estimation of the real number of cases of this rare injury compared to any other review on this subject to date.

Abstract
Purpose
To analyse the degree of pneumatisation of the temporal bone when there is an association between dehiscence of the superior semicircular canal and dehiscence of the tegmen tympani.

Materials and methods
We analysed a retrospective CT study of 124 selected cases. A single inclusion criterion was applied: the presence of a dehiscence of the tegmen tympani. On the other hand, the degree of temporal pneumatisation was assessed by axial and coronal planes, and has been divided into the following grades O, I, II and III, according to the status and relationship of the mastoid, the bony labyrinth, the petrous segment of the carotid canal and sigmoid sinus.

Results
Of the 124 cases studied, 35 (28.2%) presented both dehiscences. In 26 of the 35 (47.3%), grade II pneumatisation, 4 (14,8%), grade I, and 5 (11,9%) grade III was observed, with a statistically significant relationship (p < 0.001). On the other hand, we did not find a significant relationship when relating both dehiscences in any age or sex group. However, when relating the degree of pneumatisation to sex, among those with grade III pneumatisation, the proportion of men (52.4%) was significantly higher than that of women (47.6%) (p = 0.017).

Conclusion
We have detected a statistically significant relationship between the coexistence of grade II pneumatisation and the presence of both dehiscences in the temporal bone.

AbstractCryptosporidium is a major cause of diarrhoeal disease and mortality in young children in resource-poor countries, for which no vaccines or adequate therapeutic options are available. Infection in humans is primarily caused by two species: C. hominis and C. parvum. Despite C. hominis being the dominant species infecting humans in most countries, very little is known about its growth characteristics and life cycle in vitro, given that the majority of our knowledge of the in vitro development of Cryptosporidium has been based on C. parvum. In the present study, the growth and development of two C. parvum isolates (subtypes Iowa-IIaA17G2R1 and IIaA18G3R1) and one C. hominis isolate (subtype IdA15G1) in HCT-8 cells were examined and compared at 24 h and 48 h using morphological data acquired with scanning electron microscopy. Our data indicated no significant differences in the proportion of meronts or merozoites between species or subtypes at either time-point. Sexual development was observed at the 48-h time-point across both species through observations of both microgamonts and macrogamonts, with a higher frequency of macrogamont observations in C. hominis (IdA15G1) cultures at 48-h post-infection compared to both C. parvum subtypes. This corresponded to differences in the proportion of trophozoites observed at the same time point. No differences in proportion of microgamonts were observed between the three subtypes, which were rarely observed across all cultures. In summary, our data indicate that asexual development of C. hominis is similar to that of C. parvum, while sexual development is accelerated in C. hominis. This study provides new insights into differences in the in vitro growth characteristics of C. hominis when compared to C. parvum, which will facilitate our understanding of the sexual development of both species.

Published: September 2023

AbstractThe corrosion behavior of electrodeposited nickel-based coatings with W, Mo, and TiOx as potential catalytic material for hydrogen evolution reaction (HER) in highly aggressive media, 0.5 M H2SO4 and 6 M KOH, is presented. A wide range of electrochemical and spectroscopic methods have been used, such as linear sweep voltammetry, open-circuit potential (OCP), electrochemical impedance spectroscopy (EIS), X-ray diffraction (XRD), X-ray fluorescence spectroscopy (XRF), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and energy-dispersive spectroscopy (EDS) to characterize the coatings before and after a residence time of 336 h in the model corrosion environment. The NiW alloy and the NiWTiOx composite coating demonstrate the best corrosion resistance in an acidic environment due to the stable tungstate phase formation (H0.33O3W and H2O4W) on the surface. In alkaline environments, all the systems studied show enviable resistance, but the alloys containing molybdenum stand out.
Accelerated multi-hillshade hierarchic clustering for automatic lineament extraction
Authors: Kaas Ondřej , Šilhavý Jakub , Kolingerová Ivana , Čada Václav 
Published: September 2023

AbstractThe lineaments are linear features reflecting mountain ridges or discontinuities in the geological structure. Lineament extraction is not an easy problem. Recently, an automatic approach based on multi-hillshade hierarchic clustering (MHHC) has been developed; the approach is based on line extraction from a raster image. An essential part of this approach is spatial line segment clustering, a powerful but relatively slow tool. This paper presents a modification of MHHC, which solves the spatial line segment clustering as a facility location problem. The proposed modification is faster than MHHC while not changing the method’s core.

Abstract
Purpose
In Japan, Japan’s Ministry of Health, Labor, and Welfare decided to suspend govermental recommendation for HPV vaccination in FY 2013. The HPV vaccination rate for those born in FY 2000 or thereafter declined dramatically. In 2021, the “suspension of recommendation” ended. The catch-up vaccinations for the unvaccinated have been offered nationwide from FY 2022 to FY 2024. We aimed to quantify the vaccination intentions and characteristics of those young women now eligible for catch-up vaccination.

Methods
In February of 2022, we conducted an internet survey targeted women who were born in 1997–2004 but who had not yet been HPV vaccinated.

Results
We received 1,648 valid responses. 41.6% of the respondents wanted to uptake the catch-up HPV vaccination, 29.7% were undecided, and 28.7% did not want to be vaccinated. The intention to uptake catch-up HPV vaccination was associated with a good history of gynecological visits, intention to receive cervical cancer screening, sexual activity, degree of anxiety about cervical cancer, familiarity with problems associated with cervical cancer, experience with vaccination recommendations, and knowledge about cervical cancer (p < 0.05, respectively). In the vaccinated generation, the proportion of the group that did not want to be vaccinated was significantly higher (p < 0.05). In the vaccine-suspended generation, the proportion of the group that wanted to be vaccinated was significantly higher (p < 0.05).

Conclusion
Our survey revealed that catch-up vaccination intentions differed depending on the vaccination environment. It is necessary for all organizations involved with HPV vaccination, such as government, medical institutions, and educational institutions, to make recommendations based on an understanding of the characteristics of the “vaccinated generation” and the “vaccine-suspended generation”.
Sedimentary phosphorus burial in three contrasting boreal lakes in Finland
Authors: Laakso Johanna , Jilbert Tom , Saarinen Timo 
Published: September 2023

AbstractPermanent phosphorus (P) burial in sediment regulates lake trophic state over long timescales, but the controls on P burial are only partially understood. A diversity of biogeochemical settings may be found in lake sediments, which may have a strong impact on the processes controlling P burial from one location to another. Here, we investigate early diagenesis of P in three contrasting lakes in Southwest Finland. Eutrophic Lake Köyliönjärvi and mesotrophic Lake Pyhäjärvi have a history of nutrient loadings from agriculture, while Lake Vähäjärvi is an oligotrophic small forest lake, leading to potentially contrasting sediment biogeochemical dynamics. We combined porewater data and solid-phase sediment geochemical data to identify P phases in each system and investigate the dominant processes controlling P burial. Porewater profiles showed opposite gradients between the oligotrophic and the mesotrophic/eutrophic systems, implying net diffusive fluxes into and out of the sediments, respectively. Furthermore, sediment P data showed contrasting P speciation. Reactive P is buried in all systems, but the role of reducible iron (Fe) oxides in P retention is greater in mesotrophic/eutrophic lakes. In the oligotrophic system, aluminium (Al) oxides controlled P sorption into the sediment after diffusion from lake water. Evidence for vivianite formation was found only in the mesotrophic Lake Pyhäjärvi sediment, where 42–47% of total P was released in a Fe(II)-P specific extraction from the deeper part of the sediment column and vivianite crystals could be isolated from sediment samples.
An ALNS-based matheuristic algorithm for a multi-product many-to-many maritime inventory routing problem
Authors: Heidari Nooshin , Hemmati Ahmad 
Published: September 2023

AbstractIn this paper, we propose an adaptive large neighborhood search-based matheuristic algorithm to solve a multi-product many-to-many maritime inventory routing problem. The problem addresses a short sea inventory routing problem that aims to find the best route and distribution plan for multiple products with a heterogeneous fleet of vessels through a network including several producers and customers. Each port can be visited a given number of times during the planning horizon, and the stock level for each product should lie within the predefined bound limits. The problem was introduced by Hemmati et al. (Eur J Oper Res 252:775–788, 2016). They developed a mixed integer programming formulation and proposed a matheuristic algorithm to solve the problem. Although their proposed algorithm worked well in terms of running time, it suffers from disregarding a part of the solution space. In this study, we propose a new matheuristic algorithm to find better solutions by exploring the entire solution space for the same problem. In our solution methodology, we split the variables into routing and non-routing variables. Then in an iterative process, we determine the values of the routing variables with an adaptive large neighborhood search algorithm, and we pass them as input to a penalized model which is a relaxed and modified version of the mathematical model introduced in Hemmati et al. (2016). The information from solving the penalized model, including the values of the non-routing variables, is then passed to the adaptive large neighborhood search algorithm for the next iteration. Several problem-dependent operators are defined. The operators use the information they get from the penalized model and focus on decreasing the penalty values. Computational results show up to 26% improvement in the quality of the solutions for the group of instances with a large feasible solution space. We get the optimal value for the remaining instances matched with the reported results.
