In the context of modern mobility, topics such as smart-cities, Car2Car-Communication, extensive vehicle sensor-data, e-mobility and charging point management systems have to be considered. These topics of modern mobility often have in common that they are characterized by complex and extensive data situations. Vehicle position data, sensor data or vehicle communication data must be preprocessed, aggregated and analyzed. In many cases, the data is interdependent. For example, the vehicle position data of electric vehicles and surrounding charging points have a dependence on one another and characterize a competition situation between the vehicles. In the case of Car2Car-Communication, the positions of the vehicles must also be viewed in relation to each other. The data are dependent on each other and will influence the ability to establish a communication. This dependency can provoke very complex and large data situations, which can no longer be treated efficiently. With this work, a model is presented in order to be able to map such typical data situations with a strong dependency of the data among each other. Microservices can help reduce complexity.

Radioisotope-guided sentinel lymph node dissection (sLND) has shown high diagnostic reliability in prostate (PCa) and other cancers. To overcome the limitations of the radioactive tracers, magnetometer-guided sLND using superparamagnetic iron oxide nanoparticles (SPIONs) has been successfully used in PCa. This prospective study (SentiMag Pro II, DRKS00007671) determined the diagnostic accuracy of magnetometer-guided sLND in intermediate- and high-risk PCa. Fifty intermediate- or high-risk PCa patients (prostate-specific antigen (PSA) >= 10 ng/mL and/or Gleason score >= 7; median PSA 10.8 ng/mL, IQR 7.4–19.2 ng/mL) were enrolled. After the intraprostatic SPIONs injection a day earlier, patients underwent magnetometer-guided sLND and extended lymph node dissection (eLND, followed by radical prostatectomy. SLNs were detected in in vivo and in ex vivo samples. Diagnostic accuracy of sLND was assessed using eLND as the reference. SLNs were detected in all patients (detection rate 100%), with 447 sentinel lymph nodes SLNs (median 9, IQR 6–12) being identified and 966 LNs (median 18, IQR 15–23) being removed. Thirty-six percent (18/50) of patients had LN metastases (median 2, IQR 1–3). Magnetometer-guided sLND had 100% sensitivity, 97.0% specificity, 94.4% positive predictive value, 100% negative predictive value, 0.0% false negative rate, and 3.0% additional diagnostic value (LN metastases only in SLNs outside the eLND template). In vivo, one positive SLN/LN-positive patient was missed, resulting in a sensitivity of 94.4%. In conclusion, this new magnetic sentinel procedure has high accuracy for nodal staging in intermediate- and high-risk PCa. The reliability of intraoperative SLN detection using this magnetometer system requires verification in further multicentric studies.

In huge warehouses or stockrooms, it is often very difficult to find a certain item, because it has been misplaced and is therefore not at its assumed position. This position paper presents an approach on how to coordinate mobile RFID agents using a blackboard architecture based on Complex Event Processing.

Wie kann man den empfundenen Alltagsstress bewältigen und eigene, sinnvolle Ziele erreichen? Woher kommt die Zeitnot und was kann man tun? Gibt es Faktoren, die Glück und Erfolg fördern? Was kann man in seinem Studien- und Arbeitsalltag tun, um sich wohl zu fühlen und erfolgreich zu sein? Welche Zeitmanagement-Tools helfen bei der Organisation von Studium und Arbeitsalltag? Diese und weitere Fragen werden im Workbook beantwortet. Der Selbstmanagement-Prozesskreis wird vorgestellt, verschiedene Modelle, Prinzipien und Techniken werden vermittelt. Mit vielen Reflexionsfragen und Übungen.

In diesem Artikel werden die Zusammenhänge zwischen Gender und Kommunikation erörtert, an Fallbeispielen und Untersuchungen erläutert und reflektiert. Der Begriff Gender beschreibt das soziale Geschlecht. Der Prozess der Kommunikation besteht aus Encodieren und Decodieren auf der nonverbalen, paraverbalen und verbalen Ebene. Dies wird unter anderem von Gender beeinflusst. Durch das Konzept des Doing Gender werden Wahrnehmungen, Kommunikationsverhalten sowie die statistischen Gegebenheiten und Rahmenbedingungen, in denen sich die Kommunikation abspielt, analysiert. Geschlechtstypische kommunikative Muster werden beschrieben und deren Grenzen durch Rahmenbedingungen reflektiert.
