4CH TX/RX Surface Coil for 7T: Design, Optimization and Application for Cardiac Function Imaging
(2010)
Practical impediments of ultra high field cardiovascular MR (CVMR) can be catalogued in exacerbated magnetic field and radio frequency (RF) inhomogeneities, susceptibility and off-resonance effects, conductive and dielectric effects in tissue, and RF power deposition constraints, which all bear the potential to spoil the benefit of CVMR at 7T. Therefore, a four element cardiac transceive surface coil array was developed. Cardiac imaging provided clinically acceptable signal homogeneity with an excellent blood myocardium contrast. Subtle anatomic structures, such as pericardium, mitral and tricuspid valves and their apparatus, papillary muscles, and trabecles were accurately delineated.

Fan sein bedeutet für viele Menschen unterschiedliche Dinge. Viele würden sich selber vielleicht nicht mal als Solche bezeichnen. Nichtsdestotrotz gibt es etwas, das diese Gruppe von Menschen verbindet: Die gemeinsame Leidenschaft für eine bestimmte Sache, die sie im Alltag nicht missen wollen. In Deutschland alleine würden sich 47.900.000 Menschen selber als Fußball-Fan bezeichnen. Und natürlich lässt sich nicht jeder dieser Menschen in den selben Topf werfen. Die Publikation „59 von 47.900.00 Fußball-Fans“ beschäftigt sich mit 59 dieser Fans, verschiedenen Wissenschaftler*innen und Psycholog*innen, um dem Fan-Sein auf den Grund zu gehen. Warum sind Menschen überhaupt Fußball-Fans? Was macht Fan-Sein aus? Und wer sind diese Ultras?

[NON]HUMAN
(2022)
"[NON]HUMAN“ ist ein 3D-animierter Kurzfilm, der in einer Zombieapokalypse spielt und sich mit dem Thema der Menschlichkeit befasst. Welche Taten können gerechtfertigt werden und welche nicht? Die Handlungsmöglichkeiten der Menschen im Zuge des Ausbruchs eines neuen Virus werfen viele moralische Fragen auf, mit denen zwischen den Zeilen gerungen wird. Denn in diesem Film bestimmen sie Leben und Tod.
Das Ziel dieser Arbeit war es, eine simple Geschichte spannend zu erzählen, indem das Publikum durch eindrucksstarke Bilder gefesselt wird. Dabei eröffnen 3D-Animationen neue Möglichkeiten, die insbesondere in den Aufnahmen der zerstörten Stadt zur Geltung kommen. Diese Arbeit zeigt spielerisch, wie sich mit etwas technischem Know-How auch ohne großem Budget hochwertige Filme drehen lässt, indem man das Potential smart ausschöpft.

(2005)
Background:
Additional stabilization of the “comma sign” in anterosuperior rotator cuff repair has been proposed to provide biomechanical benefits regarding stability of the repair.
Purpose:
This in vitro investigation aimed to investigate the influence of a comma sign–directed reconstruction technique for anterosuperior rotator cuff tears on the primary stability of the subscapularis tendon repair.
Study Design:
Controlled laboratory study.
Methods:
A total of 18 fresh-frozen cadaveric shoulders were used in this study. Anterosuperior rotator cuff tears (complete full-thickness tear of the supraspinatus and subscapularis tendons) were created, and supraspinatus repair was performed with a standard suture bridge technique. The subscapularis was repaired with either a (1) single-row or (2) comma sign technique. A high-resolution 3D camera system was used to analyze 3-mm and 5-mm gap formation at the subscapularis tendon-bone interface upon incremental cyclic loading. Moreover, the ultimate failure load of the repair was recorded. A Mann-Whitney test was used to assess significant differences between the 2 groups.
Results:
The comma sign repair withstood significantly more loading cycles than the single-row repair until 3-mm and 5-mm gap formation occurred (P≤ .047). The ultimate failure load did not reveal any significant differences when the 2 techniques were compared (P = .596).
Conclusion:
The results of this study show that additional stabilization of the comma sign enhanced the primary stability of subscapularis tendon repair in anterosuperior rotator cuff tears. Although this stabilization did not seem to influence the ultimate failure load, it effectively decreased the micromotion at the tendon-bone interface during cyclic loading.
Clinical Relevance:
The proposed technique for stabilization of the comma sign has shown superior biomechanical properties in comparison with a single-row repair and might thus improve tendon healing. Further clinical research will be necessary to determine its influence on the functional outcome.
Macroporous silicon has been etched from n-type Si, using a vertical etching cell where no rear side contact on the silicon wafer is necessary. The resulting macropores have been characterised by means of Scanning Electron Microscopy (SEM). After etching, SiO₂ was thermally grown on the top of the porous silicon as an insulating layer and Si₃N₄ was deposited by means of Low Pressure Chemical Vapour Deposition (LPCVD) as transducer material to fabricate a capacitive pH sensor. In order to prepare porous biosensors, the enzyme penicillinase has been additionally immobilised inside the porous structure. Electrochemical measurements of the pH sensor and the biosensor with an Electrolyte/Insulator/Semiconductor (EIS) structure have been performed in the Capacitance/Voltage (C/V) and Constant capacitance (ConCap) mode.
Manufacturing companies across multiple industries face an increasingly dynamic and unpredictable environment. This development can be seen on both the market and supply side. To respond to these challenges, manufacturing companies must implement smart manufacturing systems and become more flexible and agile. The flexibility in operational planning regarding the scheduling and sequencing of customer orders needs to be increased and new structures must be implemented in manufacturing systems’ fundamental design as they constitute much of the operational flexibility available. To this end, smart and more flexible solutions for production planning and control (PPC) are developed. However, scheduling or sequencing is often only considered isolated in a predefined stable environment. Moreover, their orientation on the fundamental logic of the existing IT solutions and their applicability in a dynamic environment is limited. This paper presents a conceptual model for a task-based description logic that can be applied to factory planning, technology planning, and operational control. By using service-oriented architectures, the goal is to generate smart manufacturing systems. The logic is designed to allow for easy and automated maintenance. It is compatible with the existing resource and process allocation logic across operational and strategic factory and production planning.
South Africa in recent years is the establishment of a number of research hubs involved in AI activities ranging from mobile robotics and computational intelligence, to knowledge representation and reasoning, and human language technologies. In this survey we take the reader through a quick tour of the research being conducted at these hubs, and touch on an initiative to maintain and extend the current level of interest in AI research in the country.
