Published: September 2024

Abstract
The increase in staff shortage, particularly in urgently needed care professions, is becoming an immense problem in the German healthcare system. This critical issue is further intensified by the fact that the healthcare system is still a strongly human-dependent and often insufficiently interconnected environment. Automation, medical robotics and the concept of model-based medicine can play a key role not only in addressing these issues and supporting clinical staff, but also in enabling new applications to improve patient care. While many existing approaches aim to tackle these challenges, they are generally based on current network architectures and standards and are thus constrained by the limitations of these networks. This article highlights the need for a new network approach such as 6G, which offers flexible, dynamic structures, new communication classes and many other new features in order to leverage the true potential of these new technologies.

Authors: Schrüfer Katrin V. , Noortwijck Pascal , Junger Denise , Burgert Oliver 
Published: September 2024

Abstract
This paper describes how automatic speech recognition (ASR) can be used to explore electronic patient records (EPR) in a sterile environment. As an information display, we used a system that was developed for the presentation of patient data and for supporting surgical hand disinfection. The speech recognition was performed using the Mozilla Web Speech API. A room microphone, a Jabra Box, and a directional microphone, a RØDE NT-USB Mini, were tested at various positions. Interactions with the EPR are triggered with a list of commands. The interaction was working as indented and test persons reported the system as intuitive.
Robot-assisted Neuroendoscopy: Surgeon’s Third Hand – a Proof of Concept Study
Authors: Karnam Murali , Rychen Jonathan , Guzman Raphael , Cattin Philippe C. , Rauter Georg , Gerig Nicolas 
Published: September 2024

Abstract
In neuroendoscopy, an assistant surgeon holds the endoscope while the operating surgeon performs brain surgery using surgical instruments in both hands. The assistant surgeon’s task can be strenuous over time, especially in long surgeries, and unsteadiness or tremor might affect the visualization quality that the operating surgeon depends upon. Existing mechanical and pneumatic arms offer limited flexibility. We propose a robotic assistant as a third hand to the surgeon. It holds the endoscope and can be moved freely or held in place. As a proof of concept, we attached a neuroendoscope to an offthe- shelf robot with a custom handle, including a force/torque (F/T) sensor. We qualitatively identified the requirements for the third hand with a surgeon as a participant. We also quantitatively identified the range of forces applied by the endoscope to act as a retractor on two brain phantoms while visualizing the surgical site. With our proof of concept study, we could show the feasibility of robotic assistance in neuroendoscopy. Based on our observations, we found that an intuitive input device to switch the different robot modes, a second F/T sensor to measure the surgeon’s input and tissue interaction separately, and a differently shaped precision grip handle represent promising improvements to our third hand prototype.

Authors: Schicker Martina , Tu Ha Thanh , Luder Yann , Morawska Marta , Röthlisberger Michel 
Published: September 2024

Abstract
The surgical procedure known as optic nerve unroofing plays a vital role in skull base surgery. This critical intervention focuses on relieving pressure and decompressing the optic nerve to safeguard vision, restore optimal nerve function, and enhance the surgical view during aneurysm therapy. Nevertheless, the surgical procedure presents inherent challenges and risks due to factors like limited working space, restricted surgical view, and the proximity to critical anatomical structures, including the optic nerve, carotid artery and oculomotor nerve. Significant advancements in medical robotics technology hold promise for addressing these challenges and potentially enhancing multiple aspects of neurosurgery. The objective of this study was to evaluate the feasibility and precision of utilizing CARLO© (Cold Ablation Roboterguided Laser Osteotome) for delineating the boundaries of the optical canal. Additionally, the investigation involved the insertion of a thermal probe into the optical canal to assess the occurrence of significant heat damage resulting from the removal of the optic roof. Success was defined as the accurate excavation of the optical canal, which was confirmed through post-experimental CT scans and photographic documentation. The experiment utilized five fresh frozen skulls, securely fixed in a Mayfield clamp to ensure a stable experimental setup. Prior to the procedure, preoperative planning was conducted using NeuroPlan©, which accurately segmented crucial anatomical structures and devised trajectories with a safety margin of 2mm from high-risk areas. A navigation system and additional referencing screws were employed to achieve precise bone ablation. The target structure was accessed through a pterional craniotomy and the optical canal was prepared extradurally. While data evaluation is ongoing, preliminary results indicate a successful delineation of the optical roof without significant heat damage while preserving vital anatomical structures. These initial findings have the potential to stimulate further investigation into the applications of robotic and laser technologies in the realm of neurosurgery. The study emphasizes the feasibility and exceptional precision of robotic technology, which can be utilized to advance the development of additional procedures to improve patient outcomes and reduce perioperative risks in neurosurgical interventions.
Radial–axial runner blade design using the coordinate slice technique
Authors: Koudelka Libor 
Published: September 2024

Abstract
There is a lack of information about the geometric description of radial–axial runner blades. The article aims to fill this gap using a method that exploits modern differential geometry for the description and shape modification of the runner blade. Three-dimensional Euclidean space with a curvilinear coordinate system serves as a basic manifold object, and the technique of coordinate slice gives the blade camber surface a submanifold. The camber surface definition given in the article is suitable for interactive design and optimization of the shape in a computer program optimization loop. Geometric entities and maps can be viewed as objects and methods of a computer object-oriented in-house program. The Francis runner blade serves as an example. Complete blade design contains the camber surface wrapped up with an airfoil surface, but this is not dealt with here. Basic knowledge of differential geometry and spline theory is expected.
The use of the narrative final vowel -á by the Lingala-speaking youth of Kinshasa: from anterior to near/recent past
Authors: Motingea Mangulu André 
Published: September 2024

Abstract
The aim of this paper is to try to understand why young people in Kinshasa prefer the construction with a subject marker, the verbal base, and the suffix -á (SM-VB-á) to the recent past. After looking at the narrative tense in some local languages, we first look at how this SM-VB-á tense is described for Standard Lingala, before examining its use in the Lingala youth language of Kinshasa. Finally, we investigate whether there are any manipulations at the morphosyntactic level. Without excluding the possibility of a natural shift or substrate interference, it can be postulated that a probable source of this is the French simple past with the suffix -a. The same scenario has been demonstrated with -é in the infinitive and in the perfect/recent tense with all verbs borrowed from French.
Analysis of a generalized proportional fractional stochastic differential equation incorporating Carathéodory's approximation and applications
Authors: Sultana Sobia 
Published: September 2024

Abstract
Fractional stochastic differential equations (FSDEs) with fractional derivatives describe the anomalous diffusion processes by incorporating the memory effects and spatial heterogeneities of the porous medium. The stochastic component addresses the random nature of the fluid flow due to the variability in pore sizes and connectivity. The first objective of this research is to prove the well-posedness of a class of generalized proportional FSDEs, and we acquire the global existence and uniqueness of findings under certain settings that are coherent with the classic SDEs. The secondary purpose is to evaluate the continuity of findings in fractional-order formulations. The Carathéodory approximation is taken into account for a class of generalized proportional FSDEs, which is pivotal and provides well-known bounds on the norm of the solutions. Carathéodory’s approximation aids in approximating the FSDEs governing turbulent flows, ensuring the solutions are mathematically robust and physically meaningful. As is widely documented, the existence and uniqueness of solutions to certain types of differential equations can be formed under Lipschitz and linear growth conditions. Furthermore, a class of generalized proportional FSDEs with time delays is considered according to certain new requirements. With the aid of well-known inequalities and Itô isometry technique, the Ulam–Hyers stability of the analyzed framework is addressed utilizing Lipschitz and non-Lipschitz characteristics, respectively. Additionally, we provide two illustrative examples as applications to demonstrate the authenticity of our interpretations. The demonstrated outcomes will generalize some previously published findings. Finally, this deviation from fractional Brownian motion necessitates a model that can capture the subdiffusive or superdiffusive behavior.

Abstract

99Tc has a long half-life, high fission yield, and good environmental mobility, posing a significant threat to the environment and human health. Therefore, removing technetium from radioactive wastewater is a very important and urgent task. For laboratory safety reasons, ReO4
− is often used as a non-isotopic substitute for 99TcO4
−. From this point of view, the study of the separation behavior of Re in the aqueous phase can provide a reference value for the removal of 99Tc. Here, a new type of extraction chromatography resin was prepared by impregnating the functionalized ionic liquid into the macroporous resin, whose imidazolium cations modified by amide functional groups which can effectively capture ReO4
−/TcO4
− from simulated radioactive wastewater. The results show the resin has good adsorption performance and fast adsorption kinetics (the adsorption equilibrium is about 20 min). The adsorption mechanism was investigated using Fourier transform infrared (FT-IR) spectra and X-ray photoelectron spectroscopy (XPS). It shows that the adsorption process is an anion exchange between Cl− in the resin and ReO4
− in the solution.

Published: September 2024

Rett syndrome (RTT), a severe neurodevelopmental disorder caused by mutations in the MeCP2 gene, is characterized by cognitive and social deficits. Previous studies have noted hypoactivity in the medial prefrontal cortex (mPFC) pyramidal neurons of MeCP2-deficient mice (RTT mice) in response to both social and nonsocial stimuli. To further understand the neural mechanisms behind the social deficits of RTT mice, we monitored excitatory pyramidal neurons in the prelimbic region of the mPFC during social interactions in mice. These neurons' activity was closely linked to social preference, especially in wild-type mice. However, RTT mice showed reduced social interest and corresponding hypoactivity in these neurons, indicating that impaired mPFC activity contributes to their social deficits. We identified six mPFC neural ensembles selectively tuned to various stimuli, with RTT mice recruiting fewer neurons to ensembles responsive to social interactions and consistently showing lower stimulus-ON ensemble transient rates. Despite these lower rates, RTT mice exhibited an increase in the percentage of social-ON neurons in later sessions, suggesting a compensatory mechanism for the decreased firing rate. This highlights the limited plasticity in the mPFC caused by MeCP2 deficiency and offers insights into the neural dynamics of social encoding. The presence of multifunctional neurons and those specifically responsive to social or object stimuli in the mPFC emphasizes its crucial role in complex behaviors and cognitive functions, with selective neuron engagement suggesting efficiency in neural activation that optimizes responses to environmental stimuli.Significance StatementUnlike previous studies that have only shown altered prefrontal activity in response to stimuli in MeCP2 deficient models, our study identifies specific stimulus-tuned ensembles in the prefrontal cortex and their dysregulated activity patterns underlying social deficits in Rett syndrome. Utilizing innovate neural activity visualization tools, we revealed circuit-level evidence of the impairment caused by MeCP2-deficiency. The current research not only adds to the field of neurodevelopmental disorders and insights into the neurocircuitry of social behavior, but sheds light on the circuit-level mechanisms underlying a key behavioral phenotype of Rett syndrome.

En este trabajo se estimó el rendimiento y costo de mano de obra, del material y del equipo en la aplicación de repello con mortero industrializado, estos datos son importantes para la determinación de la factibilidad de un proyecto ya que impactan directamente su costo y duración total. Las mediciones fueron realizadas en tres proyectos habitacionales de mampostería de uno y dos niveles, ubicados en Alajuela, Heredia, San José o Cartago de Costa Rica. En los primeros dos se utilizaron morteros de diferentes marcas, sin embargo, la metodología de aplicación fue manual en ambos casos. En el tercer proyecto se utilizó el mismo mortero que uno de los proyectos anteriores, pero se aplicó mecánicamente. Para el análisis de los datos obtenidos, se utilizó la prueba estadística t de student con una confiabilidad de 90%. Cabe destacar que los resultados son válidos solo para proyectos con características similares.De acuerdo con los resultados obtenidos, el costo de la actividad de repello aplicado manualmente es muy similar al aplicado con lanzadora ya que, el ahorro en el costo de mano de obra obtenido equivale aproximadamente al monto necesario para cubrir la amortización del equipo lanzador y el costo adicional del material proyectado.
Requerimientos de graduación para un agregado grueso con tamaño máximo nominal de 16 mm
Authors: Rojas Einer Rodríguez , Muñoz Umaña Flor de María , Chacón Bolívar Valeria 
Published: September 2024

En Costa Rica, la normativa de mayor empleo en materia de especificaciones para valorar la calidad de los agregados para concreto hidráulico, corresponde a la de la Sociedad Americana de Pruebas y Materiales (ASTM, por sus siglas en inglés), las cuales constituyen la base de las normas del Instituto de Normas Técnicas de Costa Rica (INTECO).
Por ende, los requerimientos de graduación de los agregados que se sigue en el país provienen de la norma ASTM C33 Especificación normalizada para agregados para concreto (INTE C15:2014). Para el diseño de mezclas, esta norma proporciona especificaciones granulométricas para tamaños máximos nominales de 90 mm, 63 mm, 50 mm, 37,5 mm, 25 mm, 19 mm, 12,7 mm y 9,5 mm.
No obstante, en estudios recientes, Hernández (2018) y Delgado (2018), utilizaron un agregado con tamaño máximo nominal de 16 mm en la elaboración de concreto hidráulico para obtener curvas estándar de desarrollo de resistencia para diferentes tipos de cemento portland que se comercializan en el país. En sus trabajos, tanto Hernández como Delgado, utilizaron agregado grueso de río y agregado grueso de tajo. Para cada caso se usó como referencia granulométrica las especificaciones para tamaños máximos nominales de 12,7 mm y 19 mm que proporciona la norma ASTM C33 (INTE C15:2014), dado que en esta norma no existen especificaciones para agregado de 16 mm.
Fuentes productoras de agregados a nivel nacional están generando una cantidad importante de agregado de 16 mm, por lo que resultó de interés realizar un estudio experimental con muestras estadísticamente válidas, que permitan comprobar con un grado de certeza adecuado la validez de usar la granulometría que mejor se ajuste (tamaño máximo nominal: 12,7 mm o 19 mm) cuando se emplea agregado de 16 mm. Pero también, como parte del estudio, se generó una propuesta de límites granulométricos para un tamaño de 16 mm.
Plotinus on perceptual memory
Authors: Lautner Péter 
Published: September 2024

AbstractThe paper has a dual purpose, one historical and one theoretical. It aims to show, first, that Plotinus' notion of perceptual memory heavily draws on Stoic views insofar as both regard memory as a linguistic phenomenon. Furthermore, it aims to answer two questions, both are intimately connected to the Plotinian thesis of the impassibility of the soul. How could it happen that a present tense perceptual judgment changes into a past tense memory judgment and what explains that our judgments on perceived objects change, and occasionally fade, over time, that is, how can we remember in a way different from sense-perception?

Published: September 2024

Background: Maize landraces show remarkable diversity and environmental adaptability in Mexico. Nevertheless, few studies have explored physiological mechanisms used by different maize landraces to grow and yield in a particular agroecological region.
Question: How do three landrace maize populations from contrasting maize races in southeastern Mexico, differ in their responses in terms of growth, chlorophyll fluorescence, and gas exchange?
Studied species: Zea mays L.
Study site and date: Yucatan, Mexico; 2017.
Methods: The field experiment followed a complete randomized block design, with six replicates. Three contrasting maize landraces were evaluated as treatments. Response variables were vegetative traits, dry matter allocation, yield components, and maize physiological responses. Data were analyzed by one-way ANOVA and post hoc Tukey multiple comparison test (P ≤ 0.05).
Results: Maize landraces showed differences in cycle length, plant morphology, and yield performance. The long cycle maize landrace Xnuc-naal, had tall plants that accumulated 17 and 21 % more dry matter than Xmejen-naal and Elotillo, respectively. The short-cycle maize landraces Elotillo and Xmejen-naal exhibit superior physiological responses leading to higher grain yields compared to the Xnuc-naal.
Conclusions: The landrace Xnuc-naal stood out for its ability in forage production, whereas Elotillo and Xmejen-naal exhibited notable physiological efficiency in grain production in southeastern Mexico.
Primary retroperitoneal choriocarcinoma with lung metastasis: Case report
Authors: Vekariya Ruta Gordhanbhai , Kanhere Shubhada 
Published: September 2024

Extragonadal germ cell tumor with choriocarcinoma in males is a rare tumor. Usually, Choriocarcinoma occurs in the midline of the body, such as the retroperitoneum and mediastinum. The B-hCG is used for diagnosis and monitoring treatment response. It is an aggressive and highly metastatic tumor with poor outcome.A 24-year-old male patient was admitted in our hospital with abdominal pain that had progressively worsened over two months andwas associated with a weight loss of 7 Kg over 2 months. Patient had no significant medical, personal, and family histories.The ultrasound abdomen showed mild hepatosplenomegaly and hepatic hemangioma. A CT scan of the thorax and whole abdomen showed multiple bilateral lung lesions with areas of arterial phase hyperenhancement. The largest lesion measured 60 x 42 mm in the left basal lung, and abdominal images showed an 86 x 68 x 90 mm lobulated left para-aortic lesion in the infrarenal location.An excision of the right lower lobe lung with nodule was done, and the histopathological findings were consistent with those of a germ cell tumor with a component of choriocarcinoma.Tumor markers, particularly serum beta human chorionic gonadotropin (B-hCG) was significantly raised with level of 917950 mIU/mL. Other tumor markers done were Lactate dehydrogenase (LDH) - 725 U/L and Alpha feto protein (AFP) -0.762 IU/ml.Patient was diagnosed with a primary retroperitoneal choriocarcinoma with metastasis to lungs and was started on urgent inpatient chemotherapy.Extragonadal choriocarcinoma always has a late presentation when these bulky tumors cause compression symptoms and metastasize to other places. Diagnosis of extragonadal choriocarcinomas requires the exclusion of metastatsis from a primary tumor in the testes and distinguishing an extragonadal GCT from another poorly differentiated cancer via histopathological and immunohistochemical examination.
