Hamartosis of the thoracolumbar vertebral column in a 3‐month‐old Rhodesian Ridgeback
Authors: Hauer Julia , Günther Charlotte , Matiasek Kaspar , Rupp Stefan , von Klopmann Thilo 
Published: July 2023

AbstractThis case report describes the clinical presentation, imaging diagnosis and histopathological findings of multiple osseous hamartomas in the thoracolumbar vertebral column of a 3‐month‐old Rhodesian Ridgeback puppy. The dog was presented due to progressive non‐painful, non‐ambulatory upper motor neuron paraparesis. Magnetic resonance imaging revealed diffuse T2‐weighted hyperintensities in the vertebral bodies of Th12, L4, S2 and the vertebral arch of Th13, and showed irregular and hyperostotic outer borders of the cortex. The diagnosis of multiple hamartomas was confirmed by histopathology showing bone cavities containing myxoid mesenchymal material, tortuous blood vessels and lipid and cartilaginous emboli in the bone marrow. This case emphasises the importance of keeping a hamartoma in mind as cause for neurological signs, especially in young animals.

Published: July 2023

AbstractA 1‐year‐old, female, domestic shorthair cat was referred for orthopaedic evaluation of acute‐onset, non‐progressive left pelvic limb lameness of 2.5‐week duration. Orthopaedic examination revealed an abnormal gait with impaired ability to support weight on the left pelvic limb. There was marked atrophy of the quadriceps muscles. Neurological examination revealed an absent patellar reflex and decreased sensation in the cutaneous zone of the saphenous nerve of the left pelvic limb. Magnetic resonance imaging showed T2‐weighted/short‐tau inversion recovery hyperintensity and contrast enhancement in the area of the femoral nerve and within muscles innervated by this nerve. Findings were deemed consistent with traumatic nerve injury and denervation/traumatic myopathy or myositis/neuritis. Electromyography of the quadriceps muscles revealed fibrillation potentials and positive sharp waves. Follow‐up over the next 9 months revealed no changes in the neurological deficits. This was deemed to be consistent with either partial axonotmesis or partial neurotmesis of the left femoral nerve.
Serial ultrasonographic measurements of fetal parameters over three successive pregnancies in a captive Eastern black‐and‐white colobus monkey (Colobus guereza)

Published: July 2023

AbstractThis study provides ultrasonographic fetal growth charts for the Eastern black‐and‐white colobus monkey (Colobus guereza). Throughout three consecutive gestations (−162 to −2 days to parturition) in a single dam, we opportunistically obtained ultrasonographic measurements for the following parameters: biparietal diameter, head circumference, humerus length, femur length, tibia length, radius length, thoracic width, kidney length, and crown‐rump length. Biparietal diameter was the most consistently measured parameter. First detection of fetuses occurred between 96 and 162 days before parturition. This report demonstrates that voluntary transabdominal ultrasound can be well‐tolerated in the colobus monkey using operant conditioning. These findings may be useful to assess fetal development and predict parturition dates in the absence of a known conception date in this species.
Introduction: Tracing Entanglements in the Seventeenth Century Caribbean
Authors: Kullberg Christina 
Published: July 2023

AbstractThis introductory theoretical chapter makes the case for reading seventeenth-century French travel writing to the Caribbean in situ. Using Édouard Glissant’s notion of point of entanglement, it argues for a shift in perspectives that would seek to undo the colonial bias of early modern texts and seek other entangled ramifications of French Caribbean literature. In so doing, the book brings attention to ways in which enslaved and Indigenous peoples actively contributed to shaping early colonial society and, indeed, the representations of it. The first section discusses discourses of silencing around French coloniality in the period and presents the theoretical points of departures that have been guiding the work. The following section is devoted to a more thorough discussion of the notion of baroque and how this book uses it as an operative concept to read through the entanglements of travel writing. The third section gives a contextual framing for the analysis. It sketches the history of the period that the travel narratives describe and presents the population of the islands. Finally, the fourth section offers a more detailed account of the travelogues, their writers and the predicaments that dictated these texts, and ends by outlining the chapters or points of entanglement that will be approached, namely geography, the self, and language.
Searchable Symmetric Encryption
Authors: Krähenbühl Cyrill , Perrig Adrian 
Published: July 2023

AbstractSearchable symmetric encryption allows operating on encrypted data, particularly keyword-based search on documents and range-based search on spatial data. Various methods can be used in Searchable symmetric encryption, such as order-preserving or fully homomorphic encryption, for different levels of information leakage. New schemes with more efficient search operations and reduced access and search pattern leakage that support novel settings, such as dynamic data sets and multiple users, have been proposed in the last few years. Especially with the emergence of cloud storage, encrypting sensitive remote data while preserving the ability to operate efficiently is an ample opportunity for the military and industry. However, there are risks when deploying Searchable symmetric encryption that must be considered since some Searchable symmetric encryption schemes proposed in the past have been (completely) broken by the research community.

Published: July 2023

AbstractAny trend assessment concerning data protection and encryption technologies constitutes a challenging task for various reasons. The swift development of security technologies brings a myriad of novel protocols, tools, and procedures whose technological readiness levels also evolve rapidly. We used a benchmarking development indicator, the attention brought by different communities, to perform the analysis. This attention was measured through a scientometric analysis of the production of scientific works, and the public attention was given to these technologies through Wikipedia pageviews. This analysis provides valuable insights into the development of data protection and encryption technologies and their impact on the security landscape.
Sporify: An Automated Tool to Quantify Spores in Z-Stacked 3D Samples

Published: July 2023

AbstractIn recent years, fungi have attracted avid interest from the research community. This interest stems from several motives, including their network creation capabilities and fundamental role in the ecosystem. Controlled laboratory experiments of fungal behaviors are crucial to further understanding their role and functionalities.In this paper, we propose a method for automating the quantification and observation of fungal spores. Our approach consists of four steps: 1) a Z-stack image acquisition of the sample is performed, 2) a detection algorithm is applied to all Z-planes, 3) clustering of spores detected in different Z-planes, 4) determination of the optimal Z-plane for each cluster through an ad-hoc focus measure. We compared the spore count obtained through the automated tool to a manual count and the count obtained by applying the detection algorithm to a single plane. The result is a highly automated, non-invasive tool to determine spore count, estimate each spore depth, and retrieve an all-in-focus image to analyze further.
On Unsteady Internal Flows of Incompressible Fluids Characterized by Implicit Constitutive Equations in the Bulk and on the Boundary
Authors: Bulíček Miroslav , Málek Josef , Maringová Erika 
Published: July 2023

AbstractLong-time and large-data existence of weak solutions for initial- and boundary-value problems concerning three-dimensional flows of incompressible fluids is nowadays available not only for Navier–Stokes fluids but also for various fluid models where the relation between the Cauchy stress tensor and the symmetric part of the velocity gradient is nonlinear. The majority of such studies however concerns models where such a dependence is explicit (the stress is a function of the velocity gradient), which makes the class of studied models unduly restrictive. The same concerns boundary conditions, or more precisely the slipping mechanisms on the boundary, where the no-slip is still the most preferred condition considered in the literature. Our main objective is to develop a robust mathematical theory for unsteady internal flows of implicitly constituted incompressible fluids with implicit relations between the tangential projections of the velocity and the normal traction on the boundary. The theory covers numerous rheological models used in chemistry, biorheology, polymer and food industry as well as in geomechanics. It also includes, as special cases, nonlinear slip as well as stick–slip boundary conditions. Unlike earlier studies, the conditions characterizing admissible classes of constitutive equations are expressed by means of tools of elementary calculus. In addition, a fully constructive proof (approximation scheme) is incorporated. Finally, we focus on the question of uniqueness of such weak solutions.

Published: July 2023

AbstractX-ray computed tomography was applied in imaging 3D-printed gyroids used for bioseparation in order to visualize and characterize structures from the entire geometry down to individual nanopores. Methacrylate prints were fabricated with feature sizes of 500 µm, 300 µm, and 200 µm, with the material phase exhibiting a porous substructure in all cases. Two X-ray scanners achieved pixel sizes from 5 µm to 16 nm to produce digital representations of samples across multiple length scales as the basis for geometric analysis and flow simulation. At the gyroid scale, imaged samples were visually compared to the original computed-aided designs to analyze printing fidelity across all feature sizes. An individual 500 µm feature, part of the overall gyroid structure, was compared and overlaid between design and imaged volumes, identifying individual printed layers. Internal subvolumes of all feature sizes were segmented into material and void phases for permeable flow analysis. Small pieces of 3D-printed material were optimized for nanotomographic imaging at a pixel size of 63 nm, with all three gyroid samples exhibiting similar geometric characteristics when measured. An average porosity of 45% was obtained that was within the expected design range, and a tortuosity factor of 2.52 was measured. Applying a voidage network map enabled the size, location, and connectivity of pores to be identified, obtaining an average pore size of 793 nm. Using Avizo XLAB at a bulk diffusivity of 7.00 × 10−11 m2s−1 resulted in a simulated material diffusivity of 2.17 × 10−11 m2s−1 ± 0.16 × 10−11 m2s−1.

Authors: Dittrich Tilmann , Lippert Hans-Dieter 
Published: July 2023

ZusammenfassungDer Klimawandel wird als eine der größten Herausforderungen der Gesellschaft in den nächsten Jahrzehnten bis Jahrhunderten gesehen. Ein Fokus gesetzgeberischer Aktivitäten liegt daher auf dem Themenkomplex der Nachhaltigkeit. So wurde auf EU-Ebene im Januar 2023 eine umfassende nichtfinanzielle Berichtspflicht etabliert. Im Bereich der Nachhaltigkeit in Lieferketten sind sowohl die EU als auch der nationale Gesetzgeber aktiv. Hieraus ergeben sich bereits jetzt und in Zukunft erst recht auch Rechtspflichten für die Akteure des Gesundheitswesens. Zudem zeichnet sich aufgrund einer EU-Richtlinie ein Kritis-Dachgesetz ab, das Akteure des Gesundheitswesens zu Schutzmaßnahmen vor Naturereignissen verpflichten wird. Hierüber vermittelt der Beitrag einen Überblick. Er geht außerdem auf eine mögliche Erweiterung des SGB V im Bereich der Nachhaltigkeit ein.
Early complications of percutaneous K-wire fixation in pediatric distal radius fractures—a prospective cohort study
Authors: Wasiak Michał , Piekut Maciej , Ratajczak Karol , Waśko Marcin 
Published: July 2023

Abstract
Introduction
Distal radius fractures (DRF) are the most common pediatric fractures, but the current evidence for management remains inconclusive. Closed reduction and percutaneous pinning (CRPP) provide excellent stability but are not complications-free. Therefore, a thorough evaluation of their adverse events is necessary to provide reliable information on risks and benefits in different clinical scenarios. The current literature lacks studies conducted with rigorous grading systems and uniform follow-up protocols on this topic. This prospective cohort study used a validated grading scheme to analyze complications associated with CRPP in an unselected pediatric population with displaced, unstable distal third radius fractures.

Materials and methods
One hundred and nineteen DRFs (one hundred and sixteen patients) treated with CRPP were enrolled in the study. All patients were followed 4 weeks, 5 weeks, 3 months, and 6 months after the surgery. The same protocol, comprising structured history, physical and radiological assessment, was used throughout the study. All data were prospectively abstracted. The Clavien–Dindo–Sink grading system was used to assess the complications and the Dahl score to evaluate the pin sites.

Results
Forty-two wrists (35,3%) had CDS grade I or II complications, and two (1,7%) had a grade III complication. The general complication rate for the study group was 37% (44 complications). Two patients required repeated surgery—deep bone pin-track infection treated with the Masquelet technique and surgical removal of a migrated pin. Among minor complications, pin-site inflammations were the most common—40 wrists (33,6%).

Conclusions
The CRPP is a safe treatment method for DRF in pediatric patients, with a low major complication rate. However, minor adverse events are frequent and can significantly burden the patient’s postoperative well-being. The application of rigorous definitions and grading systems should not only lead to the obtainment of high-quality data but also to higher awareness of possible pin tract infections and therefore allow for better therapeutic decisions.
Basins of Escape of the Particle’s Planar Motion in the Rectilinear (3 $$\varvec{+}$$ 1)-Body Ring Problem
Authors: Belgharbi Ibrahim , Navarro Juan F. 
Published: July 2023

AbstractThe objective of this work is to study the motion of an infinitesimal particle in the gravitational field of three big bodies in a ring configuration consisting of two peripheral and one central bodies, when the energy of the particle does not allow the escape from the potential well of the system. We have numerically determined the basins of escape using a new surface of section. Additionally, we have computed and analyzed the geometry of the set of asymptotic trajectories of the periodic orbit that governs the escape from the neighborhood of one of the two satellites, which also defines the limiting curves of the basins of escape from this region.

Published: July 2023

Abstract
Objectives
Postoperative flap monitoring is essential in oral microvascular reconstruction for timely detection of vascular compromise. This study investigated the use of attached surface probes for the oxygen-2-see (O2C) analysis system (LEA Medizintechnik, Germany) for intraoral flap perfusion monitoring.

Materials and methods
The study included 30 patients who underwent oral reconstruction with a microvascular radial-free forearm flap (RFFF) or anterolateral thigh flap (ALTF) between 2020 and 2022. Flap perfusion was measured with attached (3-mm measurement depth) and unattached surface probes (2- and 8-mm measurement depths) for the O2C analysis system at 0, 12, 24, 36, and 48 h postoperatively. Flap perfusion monitoring with attached surface probes was evaluated for cut-off values for flap blood flow, hemoglobin concentration, and hemoglobin oxygen saturation indicative of vascular compromise and for accuracy and concordance with unattached surface probes.

Results
Three RFFFs were successfully revised, and one ALTF was unsuccessfully revised. The cut-off values indicative of vascular compromise for flap perfusion monitoring with attached surface probes were for RFFF and ALTF: blood flow < 60 arbitrary units (AU) and < 40AU, hemoglobin concentration > 100AU and > 80AU (both > 10% increase), and hemoglobin oxygen saturation < 40% and < 30%. Flap perfusion monitoring with attached surface probes yielded a 97.1% accuracy and a Cohen’s kappa of 0.653 (p < 0.001).

Conclusions
Flap perfusion monitoring with attached surface probes for the O2C analysis system detected vascular compromise accurately and concordantly with unattached surface probes.

Clinical relevance
Attached surface probes for the O2C analysis system are a feasible option for intraoral flap perfusion monitoring.
Electrochemical studies of catechol at ordinary and mesoporous platinum electrodes via convolutive voltammetry and numerical simulation methods
Authors: El-Hallag Ibrahim S. , Al-Owais Ahmed A. , El-Mossalamy Elsayed H. 
Published: July 2023

AbstractOn the normal platinum electrode and mesoporous Pt electrode, the electrochemical behaviour of catechol was studied using convolutive cyclic voltammetry and numerical simulation. The nanostructured mesoporous platinum structure was electrochemically deposited from the hexadic liquid crystalline template of C16EO8 surfactant. The electrocatalytic feature and reversibility of the mesoporous platinum electrode within the oxidation of catechol in 1.0 M HClO4 have been found to be extraordinary. At ordinary and mesoporous platinum electrodes, the separation between the peaks (∆Ep) became reduced from 430 to 75 mV vs. SCE. Catechol cyclic voltammograms show one anodic peak inside the forward scan, but the corresponding cathodic one disappears in the reverse direction, and a new peak is observed at a lower potential value at the ordinary Pt electrode. In the case of the mesoporous Pt electrode, the voltammogram gives one anodic peak inside the first scan of potential and one cathodic peak inside the reverse direction. On the basis of the electrochemical behaviour, we conclude an ECEC mechanism for the electrochemical oxidation of catechol in 1.0 M HClO4 at each electrode. A numerical simulation was used to verify the proposed electrode response.

Retrospective analysis of COVID-19 patients with Guillain–Barre, Miller–Fisher, and opsoclonus–myoclonus–ataxia syndromes—a case series
Authors: Olbert Elisabeth , Alhani Naela , Struhal Walter 
Published: July 2023

Summary
Background
In accordance with the rising number of SARS-CoV‑2 infections, reports of neurological complications have also increased. They include cerebrovascular diseases but also immunological diseases such as Guillain–Barre syndrome (GBS), Miller–Fisher syndrome (MFS), and opsoclonus–myoclonus–ataxia syndrome (OMAS). While GBS and MFS are typical postinfectious complications, OMAS has only recently been described in the context of COVID-19. GBS, MFS, and OMAS can occur as para- and postinfectious, with different underlying pathomechanisms depending on the time of neurological symptom onset. The study aimed to describe clinical features, time between infection and onset of neurological symptoms, and outcome for these diseases.

Methods
All COVID-19 patients treated in the neurological ward between January 2020 and December 2022 were screened for GBS, MFS, and OMAS. The clinical features of all patients, with a particular focus on the time of onset of neurological symptoms, were analyzed.

Results
This case series included 12 patients (7 GBS, 2 MFS, 3 OMAS). All GBS and one MFS patient received immunomodulatory treatment. Three patients (2 GBS, 1 OMAS) had a severe COVID-19 infection and received mechanical ventilation. In patients with OMAS, only one patient received treatment with intravenous immunoglobulin and cortisone. The remaining two patients, both with disease onset concurrent with SARS-COV‑2 infection, recovered swiftly without treatment. In all subgroups, patients with concurrent onset of neurological symptoms and COVID-19 infection showed a trend toward shorter disease duration.

Conclusion
All patient groups displayed a shorter disease duration if the onset of neurological symptoms occurred shortly after the COVID-19 diagnosis. In particular, both the OMAS patients with symptom onset concurrent with COVID-19 showed only abortive symptoms followed by a swift recovery. This observation would suggest different pathomechanisms for immune-mediated diseases depending on the time of onset after an infection.
Can I speak to the manager? The gender dynamics of decision-making in Kenyan maize plots

Published: July 2023

AbstractGender and social inclusion efforts in agricultural development are focused on making uptake of agricultural technologies more equitable. Yet research looking at how gender relations influence technology uptake often assumes that men and women within a household make farm management decisions as individuals. Relatively little is understood about the dynamics of agricultural decision-making within dual-adult households where individuals’ management choices are likely influenced by others in the household. This study used vignettes to examine decision-making related to maize plot management in 698 dual-adult households in rural Kenya. The results indicated a high degree of joint management of maize plots (55%), although some management decisions—notably those related to purchased inputs—were slightly more likely to be controlled by men, while other decisions—including those related to hiring of labor and maize end uses—were more likely to be made by women. The prevalence of joint decision-making underscores the importance of ensuring that both men’s and women’s priorities and needs are reflected in design and marketing of interventions to support maize production, including those related to seed systems, farmer capacity building, and input delivery.
