Coded Aperture Aided Navigation and Geolocation Systems
A micro air vehicle having a navigation system with a single camera to determine position and attitude of the vehicle using changes the direction to the observed features. The difference between the expected directions to the observed features versus the measured direction to the observed features is used to correct a navigation solution
Attachment and crying in patients with medically unexplained somatic symptoms
Mentalization deficits and disturbances in emotional functioning may contribute to somatization in patients with medically unexplained somatic symptoms (MUSS). The present study aimed to increase understanding the psychological factors that contribute to somatization by examining associations between attachment, crying attitudes and behavior, and somatic symptoms in these patients. Attachment security was measured with the Experiences in Close Relationships Questionnaire in sixty-eight outpatients diagnosed with MUSS. Somatic symptom severity was measured with the RAND-36, crying frequency, and attitudes with the Adult Crying Inventory. Patients were asked to evaluate photographs of crying individuals in order to assess the perception of crying and empathic responses to crying. Attachment anxiety was significantly related to somatic symptom severity and negative attitudes toward crying. In addition, somatic symptom severity was related to a more negative attitude toward crying and less awareness of the interpersonal impact of crying on others. The association between attachment anxiety and somatic symptoms was, however, not mediated by crying or negative attitude toward crying. Neither were there significant associations between attachment, somatic symptoms, and empathic responses to crying. Altered attitudes to crying may stem from a history of insecure attachment experiences and may reflect maladaptive emotion strategies in MUSS patients

Elucidating Fibroblast Growth Factor-induced kinome dynamics using targeted mass spectrometry and dynamic modeling
Fibroblast growth factors (FGFs) are paracrine or endocrine signaling proteins that, activated by their ligands, elicit a wide range of health and disease-related processes, such as cell proliferation and the epithelial-to-mesenchymal transition. The detailed molecular pathway dynamics that coordinate these responses have remained to be determined. To elucidate these, we stimulated MCF-7 breast cancer cells with either FGF2, FGF3, FGF4, FGF10, or FGF19. Following activation of the receptor, we quantified the kinase activity dynamics of 44 kinases using a targeted mass spectrometry assay. Our system-wide kinase activity data, supplemented with (phospho)proteomics data, reveal ligand-dependent distinct pathway dynamics, elucidate the involvement of not earlier reported kinases such as MARK, and revise some of the pathway effects on biological outcomes. In addition, logic-based dynamic modeling of the kinome dynamics further verifies the biological goodness-of-fit of the predicted models and reveals BRAF-driven activation upon FGF2 treatment and ARAF-driven activation upon FGF4 treatment
Spaceport Concept in Germany
DLR and partners have conducted a study to establish a spaceport in Germany. This study includes topics as the market situation/demand/viability, safety and security for the integration of operations into the airspace, the necessary licensing, the operational requirements, as well as the regulatory framework
Survival of massive allografts in segmental oncological bone defect reconstructions
Reconstructions of large segmental bone defects after resection of bone tumours with massive structural allografts have a high number of reported complications including fracture, infection and non-union. Our goal is to report the survival and complications of massive allografts in our patients. A total of 32 patients were evaluated for fracture, infection, non-union rate and survival of their massive allograft reconstructions. The average follow-up for this group was five years and three months. The total fracture rate was 13% with a total infection rate of 16%. We found a low union rate of 25%. The total survival of the allografts was 80.8% (± 18.7%) after five years. We found a five-year allograft survival of 80.8% which is comparable with other studies
