The Theory of Projection
Authors: Posch Lennart 
Published: July 2024

Abstract
Whitehead’s process philosophy offers a wide range of speculatively generalized concepts that allow for an application in transdisciplinary research. The notion of projection is an often-overlooked detail of his philosophy that not only appears in his far-reaching theory of perception, but also constitutes an integral part of his theory of extension as the formal foundation of his metaphysical project. His perceptive theory relies on the idea of projection as the fundamental ontological relationship that lifts the past into the present. Projections of sensa describe one side of the ‘double-barreled’ theory of perception and the spatial relations of the contemporary world. The microscopic projection is just as fundamental for perception and for the integrity of a relational theory of becoming, as the perceptual projection is necessary ingredient for symbolic modes of experience. The simple projection in the mode of presentational immediacy is the basis of temporary stability of events and of any perceptual situation in the biological realm. Whitehead was aware of the possible misconceptions that this term might lead to. Discussing his remarks on the hierarchical variety of different modes of projection can resolve those misconceptions and throw a new light on the importance of projection for interdisciplinary inquiries.
Der rote Adler als brandenburgischer Erinnerungsort
Authors: Werlich Ralf-Gunnar 
Published: July 2024

Zusammenfassung
Ausgehend von der Notwendigkeit der Schaffung eines Wappens für das 1990 neu begründete Bundesland Brandenburg und die Diskussionen um das 1991 gesetzlich festgelegte heraldische Hoheitszeichen des Landes beleuchtet der Beitrag zunächst anhand einiger Schlaglichter das Verhältnis der Brandenburger zu ihrem roten Adler im neuen Bundesland. Im Anschluss wird die Geschichte des Brandenburger Adlers von seinen Anfängen als Symbol der brandenburgischen Linie der Askanier bis hin zu seiner Verwendung als Symbol der Herrschaft über die Markgrafschaft und das Kurfürstentum Brandenburg unter den Dynastien der Wittelsbacher, der Luxemburger und der Hohenzollern bis zum Ausgang des Mittelalters skizziert, um dann zu fragen, inwieweit er durch seine öffentliche Präsenz in jener Zeit und in den folgenden Jahrhunderten geeignet war, zu Herausbildung einer brandenburgischen Identität beizutragen. Thematisiert werden auch die neuzeitliche Ausstattung mit kurfürstlichen Attributen sowie die Rolle konkurrierender Wappen, wie das des Reichserbmarschallamtes und das Wappen des preußischen Königs.

Authors: Hoppe Albrecht 
Published: July 2024

Zusammenfassung
Infolge von Krieg, Flucht und Vertreibung bildeten sich nach 1945 eine Vielzahl von Heimatgemeinschaften, die sich in der Bundesrepublik zu den wichtigsten Einrichtungen heimatlos gewordener Deutscher aus den ehemaligen Ostgebieten entwickelten. In den rund 40 ostpreußischen Kreis- und Stadtgemeinschaften hat sich über einen Zeitraum von mehr als einem halben Jahrhundert ein reichhaltiges Schriftgut angesammelt, in dem sich die Aufgaben und Bemühungen um die Bewahrung der Erinnerung an die verlorenen Heimatregionen und die Rekonstruktion der Orts- und Regionalgeschichte widerspiegeln. Das im Kulturzentrum Ostpreußen in Ellingen befindliche Sammlungsgut von vier Kreisgemeinschaften wurde in einem Pilotprojekt nach archivischen Grundsätzen erschlossen und für die Benutzung bereitgestellt. Gegenstand der Erschließungsarbeiten waren die Überlieferungen der Stadtgemeinschaft Königsberg, der Kreisgemeinschaften Landkreis Königsberg und Johannisburg sowie der Stadtgemeinschaft Tilsit.

Abstract
Renal cell carcinoma (RCC) often presents with tumor thrombus (TT) in the inferior vena cava (IVC), posing significant therapeutic challenges, particularly in cases of metastatic or inoperable disease. While surgical excision remains the standard treatment approach, recent advancements in radiotherapy techniques may offer alternative strategies. We present the clinical picture of a 74-year-old male with metastatic RCC, who presented with recurrent IVC-TT, detected by surveillance computed tomography imaging, and complained of mild lower leg edema. This was successfully managed with stereotactic body radiotherapy (SBRT), resulting in a slow but continuous shrinkage of the IVC-TT with almost complete regression of most lung, liver, and lymph node metastases, obtaining a full resolution of the mild bilateral leg edema. The case described here highlights the possibility of using radiotherapy as a safe and tolerable treatment for inoperable or metastatic patients with IVC-TT. Additionally, we conducted a literature review looking for evidence of the effectiveness of radiotherapy in RCC patients with IVC-TT across different treatment settings. This case-based review ultimately aims to shed light on the emerging evidence supporting the usefulness of radiotherapy in such complex clinical challenges, hopefully paving the way for well-organized trials.
Influencing Factors and Training Strategies for Boulder and Lead Athletes' Competitive Performance: A Narrative Review
Authors: Liu Sheng , Li Yuan 
Published: July 2024

ABSTRACT
With the introduction of sport climbing in the Olympics, there have been increased opportunities for refining and enhancing the sport. Improving competitive performance is a crucial objective of national development strategies. This narrative review aims to analyze the influencing factors and training strategies for the competitive performance of boulder and lead athletes, providing a reference for improving their competitive performance. Conditioning for boulder and lead involves physical, psychological, and technical training. The competitive performance of boulder and lead athletes is primarily influenced by upper-limb strength, endurance, aerobic capacity, climbing efficiency, route previewing, and psychological elements like confidence, anxiety, and focus. To improve physical fitness and competitive performance, athletes should prioritize enhancing upper-limb strength and endurance. Athletes can enhance their climbing skills and progress by engaging in various international standard climbing routes with varying levels and styles of difficulty, thereby expanding their repertoire of techniques. In addition, there should be an increased emphasis on providing psychological counseling to athletes before competition. In future research, the differences between varying training methods for athletes of different levels and genders should be further explored, along with investigating training and recovery strategies.

Amenorrhea as a presentation of Cushing’s syndrome
Authors: Alhajeri Aishah , Hajji Sulaiman , Aljenaee Khalid 
Published: July 2024

Summary
Menstrual cycle abnormalities are common in premenopausal females with Cushing’s syndrome, although the underlying mechanism is poorly understood. Signs and symptoms found in Cushing’s syndrome overlap with polycystic ovarian syndrome (PCOS). The patient is a 33-year-old female previously diagnosed by a gynecologist with PCOS and treated with oral contraceptive pills (OCPs) for 2 years. She then discontinued her OCPs without consulting a clinician, resulting in amenorrhea for 6 months, for which she presented. She also had symptoms of depression and anxiety but had no other signs and symptoms of Cushing’s syndrome, except a plethoric face. Initial lab work showed evidence of central hypogonadism (low luteinizing hormone, follicle-stimulating hormone, and estrogen), so a complete anterior pituitary hormone workup was done. Her thyroid-stimulating hormone was also low with a low free T4 level. Prolactin level was normal, but surprisingly, her AM cortisol level was high. The Cushing’s syndrome workup revealed non-suppressed cortisol after a 1 mg dexamethasone suppression test and positive 24-h urine cortisol with suppressed adrenocorticotrophic hormone. A CT scan of her adrenal glands revealed a left adrenal adenoma. She underwent a left adrenalectomy, after which her menstrual cycles became regular again, and pituitary function has recovered.

Learning points

In Cushing's syndrome, female patients can have menstrual abnormalities due to the high cortisol levels, which can affect gonadotrophin levels.

We encourage clinicians to include Cushing's syndrome in the differential diagnosis of patients with central hypogonadism.
Life-threatening airway obstruction by Riedel’s thyroiditis: a rare presentation and diagnostic dilemma
Authors: Guia Lopes Maria Leonor , Cidade José Pedro , Cunha Clara , Limbert Clotilde , Sequeira Duarte João 
Published: July 2024

Summary
Riedel’s thyroiditis is the rarest form of thyroiditis, occasionally resulting in rapid thyroid enlargement and potential tracheal obstruction. Here, we detail the case of an 81-year-old woman with a medical history including Hodgkin lymphoma, Hashimoto’s thyroiditis, and multinodular goiter. She presented to the emergency room with stridor, cervical swelling, and breathing difficulties for over 2 days. CT scans revealed substantial thyroid enlargement causing significant glottal and tracheal compression, to a minimum tracheal diameter of 7 mm. Due to the severity of the compressive symptoms, orotracheal intubation and mechanical ventilation were deemed necessary. Surprisingly, despite the initial suspicion of malignancy given the rapid growth in the elderly, subsequent cytological and histological evaluations indicated a benign form of invasive fibrous thyroiditis – Riedel’s thyroiditis. Although surgical intervention was advised, the patient declined and opted for endobronchial treatment with a prosthetic stent and subsequent treatment with systemic glucocorticoids. Following successful treatment, she was discharged within a week and resumed normal activities without respiratory distress. This case is noteworthy for its rapid benign mass growth, rare emergent presentation, and the patient’s advanced age.

Learning points

The rapid enlargement of the thyroid gland in elderly patients poses a diagnostic challenge, stemming from the higher occurrence of aggressive thyroid carcinomas.

Despite the clinical presentation, a comprehensive diagnostic workup, including fine-needle aspiration and core-needle biopsy, is crucial for accurately distinguishing between benign and malignant causes of thyroid nodule enlargement.

This case report illustrates diverse treatment options for Riedel’s thyroiditis, and the importance of individualized treatment plans based on the degree of airway obstruction, patient preferences, and response to initial interventions.

Clinicians should contemplate the inclusion of glucocorticoids in the therapeutic regimen for Riedel’s thyroiditis, particularly in cases where surgical intervention is not feasible or declined by the patient.
A post-irradiation-induced replication stress promotes RET proto-oncogene breakage

Published: July 2024

Objective
Ionizing radiation generates genomic instability by promoting the accumulation of chromosomal rearrangements. The oncogenic translocation RET/PTC1 is present in more than 70% of radiation-induced thyroid cancers. Both RET and CCDC6, the genes implicated in RET/PTC1, are found within common fragile sites – chromosomal regions prone to DNA breakage during slight replication stress. Given that irradiated cells become more susceptible to genomic destabilization due to the accumulation of replication-stress-related double-strand breaks (DSBs), we explored whether RET and CCDC6 exhibit DNA breakage under replicative stress several days post-irradiation of thyroid cells.

Methods
We analyzed the dynamic of DNA replication in human thyroid epithelial cells (HThy-ori-3.1) 4 days post a 5-Gy exposure using molecular DNA combing. The DNA replication schedule was evaluated through replication-timing experiments. We implemented a ChIP-qPCR assay to determine whether the RET and CCDC6 genes break following irradiation.

Results
Our study indicates that replicative stress, occurring several days post-irradiation in thyroid cells, primarily causes DSBs in the RET gene. We discovered that both the RET and CCDC6 genes undergo late replication in thyroid cells. However, only RET’s replication rate is notably delayed after irradiation.

Conclusion
The findings suggest that post-irradiation in the RET gene causes a breakage in the replication fork, which could potentially invade another genomic area, including CCDC6. As a result, this could greatly contribute to the high prevalence of chromosomal RET/PTC rearrangements seen in patients exposed to external radiation.

Published: July 2024

Let F be a nonempty family of graphs. A graph 𝐺 is called F -free if it contains no graph from F as a subgraph. For a positive integer 𝑛, the planar Turán number of F, denoted by exp (𝑛, F), is the maximum number of edges in an 𝑛-vertex F -free planar graph.Let Θ𝑘 be the family of Theta graphs on 𝑘 ≥ 4 vertices, that is, graphs obtained by joining a pair of non-consecutive of a 𝑘-cycle with an edge. Lan, Shi and Song determined an upper bound exp (𝑛, Θ6) ≤ 18𝑛/7−36𝑛/7, but for large 𝑛, they did not verify that the bound is sharp. In this paper, we improve their bound by proving exp (𝑛, Θ6) ≤ 18𝑛/−48𝑛/7 and then we demonstrate the existence of infinitely many positive integer 𝑛 and an 𝑛-vertex Θ6-free planar graph attaining the bound.

Published: July 2024

Abstract
Resonance frequency and seismic-wave velocity monitoring are both important for structural health monitoring (SHM). However, the limited number of vibration sensors or seismometers in most buildings necessitates the study of the sensitivity of monitoring indicators to ensure effective monitoring while reducing data acquisition costs and processing time. This study compares the changes in resonance frequency and seismic-wave velocity under ambient noise and a regional seismic event. Resonance frequency is calculated by power spectral density, whereas seismic-wave velocity is estimated using impulse response function and moving-window cross-spectrum methods. The results indicate that relative resonance frequency changes are more suitable for overall SHM due to its higher sensitivity and lower instrument requirements. Moreover, the time–frequency analysis method provides higher resolution results in resonance frequency during seismic events, a precision that seismic velocity methods cannot achieve.
Estudio experimental del desempeño termodinámico y ambiental en motores diésel operando con mezclas de diésel y biodiésel verde de palma/girasol
Authors: Orjuela Abril Martha 
Published: July 2024

Introducción— En la actualidad, el consumo de recursos fósiles cada vez es mayor debido a los procesos industriales y el crecimiento económico. Esto ha provocado graves problemas ambientales y un riesgo de agotamiento de estos recursos.
Objetivos— En este estudio se evalúa la influencia de diferentes mezclas de biodiesel producidas a partir de los residuos de aceite de girasol y los residuos líquidos industriales de aceite de palma, en las características del proceso de combustión, rendimiento y emisiones contaminantes de CO2, HC, NOx y opacidad de humo.
Metodología— Se desarrollaron pruebas experimentales en un motor diesel monocilíndrico. En el cual, se probaron dos mezclas de biodiesel PB2SB4 y PB4SB4. El motor funcionó en cuatro modos diferentes. Además, se realizó un modelo de diagnóstico para monitorear el efecto del biodiesel en la presión del proceso de combustión y en las tasas de liberación de calor.
Resultados— Las curvas de presión en el cilindro disminuyen a medida que aumenta el porcentaje de biodiesel en el combustible. Del mismo modo, los resultados mostraron una disminución en la tasa de liberación de calor para las mezclas de biodiesel. Este efecto se puede apreciar al considerar la eficiencia de freno, en el cual las mezclas PB2SB4 y PB2SB4 muestran una reducción de 3.8% y 5.4% en comparación con diésel. El análisis de las emisiones contaminantes mostró que el biodiesel procedente de los residuos de aceite de palma y girasol permite una disminución en las emisiones de CO2, HC y opacidad de humo en un 21%, 18.5% y 10% al compararlo con el diésel comercial, respectivamente. Sin embargo, se observó un incremento en las emisiones de NOx.
Conclusiones— Las mezclas de biodiesel procedentes de los residuos de aceite de palma y aceite de girasol no producen un cambio significativo en el proceso de combustión, consumo, y en el rendimiento del motor, siempre que el porcentaje de sustitución se mantenga en un nivel inferior al 8%. Adicionalmente, este tipo de biodiesel permite reducciones en las emisiones de CO2, HC y opacidad de humo.
Framework para la elicitación de requisitos de interoperabilidad en el contexto de sistemas organizacionales
Authors: Paz Perafán Daniel Eduardo , Pino Correa Francisco José , Buitrón Ruiz Sandra Lorena 
Published: July 2024

Introducción— Dentro de la elicitación de requisitos los stakeholders generalmente no logran articular requisitos de interoperabilidad (RI) acordes a las necesidades del negocio, debido a que las organizaciones se enfocan en aspectos técnicos de las soluciones en lugar de realizar sistemáticamente un análisis holístico de la interoperabilidad y su relación con aspectos del negocio.
Objetivo: Describir un framework que orienta desde la perspectiva de negocio, la captura y especificación de RI que pueden presentarse entre los sistemas organizacionales que componen los procesos de una organización.
Metodología— Fue utilizado el método de investigación-acción para definir y aplicar cada uno de los componentes del framework propuesto a partir de cuatro ciclos de investigación y tres ciclos de resolución de problemas en los cuales se aplicó la técnica de estudios de caso.
Resultados— El marco está constituido por cuatro componentes, un conjunto de heurísticas que permiten identificar RI, un modelo que describe los atributos que constituyen la interoperabilidad a nivel de negocio, un proceso que orienta la captura de RI, y una guía para especificar los RI. Por otra parte, los RI desde la perspectiva del negocio se plantean como partida para el desarrollo de los aspectos que se deben abordar en los niveles inferiores de interoperabilidad correspondientes a procesos, servicios y datos.
Conclusiones— A través de tres estudios de caso, se describe la experiencia en la aplicación de la propuesta en dos organizaciones. Los resultados iniciales muestran que el framework es útil, práctico y adecuado para abordar la elicitación de RI.
