Cancer vaccines typically depend on cumbersome and expensive manipulation of cells in the laboratory, and subsequent cell transplantation leads to poor lymph-node homing and limited efficacy. We propose that materials mimicking key aspects of bacterial infection may instead be used to directly control immune-cell trafficking and activation in the body. It is demonstrated that polymers can be de...

In diesem Bericht werden verschiedene Imputationsmechanismen f ur fehlende Kovariablen in einem linearen Regressionsmodell mit zwei Ko variablen untersucht Hierbei ist eine der Kovariablen vollst andig beobach tet die andere nur teilweise Die betrachteten Imputationsmechanismen sind Zero Order Regression ZOR First Order Regression FOR First Order Regression plus random noise FOR und Modi ed Fir...

The purpose of introducing ultrasonic vibrations in the tube hydroforming process is to create more formability by obtaining a lower corner radius, improve thickness distribution of the wall and provide good tribological conditions at the tube and the die interface. Vibrations imposed on the die create alternating gaps which improve the formability in the tube hydroforming process in the presen...

Zusammenfassung. Wir präsentieren die integrierte Visualisierung von linksventrikulären Funktionsparametern, First-Pass (FP) Perfusionsund Late Enhancement (LE) Daten für die Diagnostik der Koronaren Herzkrankheit (KHK). Die Visualisierung basiert auf einem 3dModell des linken Ventrikels und einfachen geometrischen Primitiven (Glyphen), deren Farbe und Größe in Abhängigkeit von den Datenwerten ...

In aluminum extrusion, a work-piece (billet) is pressed through a die with an opening that closely resembles the desired shape of a profile. By this process, long profiles with an enormous variety of cross-sections can be produced to serve different markets such as building, construction and transport industry. When the shape of a profile does not conform to the specifications defined by the cu...

Short-range, point-to-point communications for mobile users enjoy increasing popularity, particularly with the rise in Bluetooth-equipped mobile devices. Unfortunately, virus writers have begun exploiting lax security in many mobile devices and subsequently developed malware exploiting proximity-based propagation mechanisms (e.g. Cabir or CommWarrior). So, if given an ad-hoc network of such mob...

Das Thema Testen spielt derzeit in der Grundausbildung der Softwareentwicklung oft nur eine untergeordnete Rolle. Entsprechend entwickeln die Studierenden wenig Erfahrung im Erstellen von Unit-Tests und kaum Bewusstsein für deren Bedeutung. Durch den Ansatz “Objects first, Tests second“ rückt die Thematik des automatisierten Testens in den Vordergrund der Ausbildung in Softwareentwicklung. 1 Mo...

Because of the energy load imbalance of cluster nodes in wireless sensor networks, this causes cluster heads tend to die earlier in the case of more tasks and routing problem such as larger energy loss, so an adaptive energy optimization clustering routing algorithm is proposed. The node residual energy and distance are taken into full consideration by the measure coefficient on the cluster-hea...

direct regenerations by using mature cotyledonary node as a explants has been shown to be time-saving and convenient strategy for micropropagation of soybean. so we have evaluated regeneration protocol through single shoot using cotyledonary node as a rapid and efficient protocol for two soybean cultivars and one mutant line. cotyledonary nodes explants obtained from 7-days-old in vitro seedlin...
