Malignant phyllodes tumor in a patient with hereditary retinoblastoma: a case report and literature review

Patients with hereditary retinoblastoma are at increased risk for second malignancies, most notably sarcomas, particularly after treatment with radiation. Malignant phyllodes tumor is a rare secondary malignancy in these patients. We present a review of the literature and report of a patient with hereditary retinoblastoma who developed two secondary malignancies, including malignant phyllodes tumor. The patient’s phyllodes tumor presented as a palpable breast mass with suspicious findings on mammogram and ultrasound. The mass was shown to be at least a borderline phyllodes tumor via sonographic percutaneous biopsy and confirmed malignant phyllodes tumor on final surgical excision

A DFT+U study of the structural, electronic, magnetic, and mechanical properties of cubic and orthorhombic SmCoO3

SmCoO3 is a perovskite material that has gained attention as a potential substitute for La1−xSrxMnO3−d as a solid oxide fuel cell cathode. However, a number of properties have remained unknown due to the complexity of the material. For example, we know from experimental evidence that this perovskite exists in two different crystal structures, cubic and orthorhombic, and that the cobalt ion changes its spin state at high temperatures, leading to a semiconductor-to-metal transition. However, little is known about the precise magnetic structure that causes the metallic behavior or the spin state of the Co centers at high temperature. Here, we therefore present a systematic DFT+U study of the magnetic properties of SmCoO3 in order to determine what magnetic ordering is the one exhibited by the metallic phase at different temperatures. Similarly, mechanical properties are difficult to measure experimentally, which is why there is a lack of data for the two different phases of SmCoO3. Taking advantage of our DFT calculations, we have determined the mechanical properties from our calculated elastic constants, finding that both polymorphs exhibit similar ductility and brittleness, but that the cubic structure is harder than the orthorhombic phase

Local structure change evidenced by temperature-dependent elastic measurements: Case study on Bi1/2Na1/2TiO3-based lead-free relaxor piezoceramics

The temperature-dependent Young's modulus Y(T) of the lead-free piezoceramics of 0.8Bi(1/2)Na(1/2)TiO(3)-0.2Bi(1/2)K(1/2)TiO(3) (20BKT) and 0.96(0.8Bi(1/2)Na(1/2)TiO(3)-0.2Bi(1/2)K(1/2)TiO(3))-0.04 BiZn1/2Ti1/2O3 (4BZT) is measured with the impulse excitation technique and contrasted with corresponding dielectric and structural data. While the dielectric properties suggest a phase transition, the high resolution XRD patterns remain virtually unchanged from room temperature up to high temperatures, confirming no change in their long-range order. In contrast, the elastic properties indicate a broad and diffuse ferroelastic transition denoted by a minimum in Y(T). By analogy to the elastic and dielectric data of PbZrxTi1-xO3 and PLZT, it is concluded that 20BKT and 4BZT are relaxors with polar nanoregions embedded in a metrically cubic matrix. Interestingly, no indication for the freezing temperature was reflected in any of the employed measurement techniques. From the saturation of Y(T), it is suggested that the Burns temperature may be approximated as 700 degrees C. Moreover, it is found that the modification with the ternary end-member BiZn1/2Ti1/2O3 results in an increase in Young's modulus. A comparison with the Bi1/2Na1/2TiO3-BaTiO3-K0.5Na0.5NbO3 yields the same results.open0

Advanced lost foam from casting technology

Previous research made significant advances in understanding the Lost Foam Casting (LFC) Process and clearly identified areas where additional research was needed to improve the process and make it more functional in an industrial environment. The current project focused on five areas listed as follows: Task 1: Precision Pattern Production Task 2: Pattern Coating Consistency Task 3: Sand Fill and Compaction Effects Task 4: Pattern Gating Task 5: Mechanical Properties of Castings. This report summarizes the work done under the current contract in all five areas in the period of October 1, 1994 through December 31, 1995. Twenty-eight (28) companies jointly participate in the project. These companies represent a variety of disciplines, including pattern designers, pattern producers, coating manufacturers, plant design companies, compaction equipment manufacturers, casting producers, and casting buyers

Values - reviewing the construct and drawing implications for values work in organisation and leadership. Kap. 2

I: H.Askeland, G. Espedal, B. Jelstad Løvaas & S. Sirris (Eds.), Understanding values work : Institutional perspectives in organizations and leadershipThis chapter outlines the trajectory of values, particularly within streams of organisational institutionalism, in order to analyse its application to values work in organisation and leadership. Conveying a frame for discussing values work, it aims at clarifying how to conceptualise the term values. Discussing classic and recent contributions, the chapter proposes seeing values as individual and collective conceptions of desirable trans-situational behaviours, objectives and ideals, serving to guide or valuate practice. Despite being an essential part of defining organisational institutionalism, and its sub-streams, values are seldom explicated. Utilising values in organisational and leadership research requires attention to their situatedness in contexts, and this chapter argues they are salient to organisations operating in pluralistic institutional environment. Studying values work, attention should be given to who and how such work is performed.publishedVersio

Grundfragen des Schadenersatzrechts aus rechtsvergleichender Sicht

The volume contains the critical responses from the perspective of other legal systems to the propositions Helmut Koziol puts forward in 2012 in his book “Basic Questions of Tort Law from a Germanic Perspective”. These reports not only describe the legal situation in selected legal systems, but also give a critical response to the propositions developed in respect of the Germanic legal family. Moreover, they consider the possible incorporation or rejection of the said propositions into the legal systems. This study is not only intended to promote mutual understanding between the individual legal systems but also to provide a basis for them to gradually grow together by means of both the internal development of the national legal systems and supranational elaboration of bodies of rules. English Version: http://e-book.fwf.ac.at/o:815Der vorliegende Band enthält zunächst die kritischen Stellungnahmen aus dem Blickwinkel anderer Rechtsordnungen zu Helmut Koziols Thesen, die er 2012 im Band „Basic Questions of Tort Law from a Germanic Perspective“ vorgelegt hat. In diesen Berichten wird nicht nur die Rechtslage in der jeweiligen Rechtsordnung geschildert, sondern es wird kritisch zu den im deutschen Rechtskreis entwickelten Thesen Stellung genommen, aber auch auf deren mögliche Berücksichtigung oder Ablehnung bei der Weiterentwicklung dieser Rechtsordnung eingegangen. Mit dieser Untersuchung soll nicht nur das Verständnis zwischen den einzelnen Rechtsordnungen gefördert, sondern auch eine Grundlage für ein allmähliches Zusammenwachsen durch die innere Fortentwicklung der nationalen Rechtsordnungen aber auch durch überstaatliche Ausarbeitung von Regelungswerken geschaffen werden.

The Network Structure of Childhood Psychopathology in International Adoptees

International adoptees are at an increased risk of emotional and behavioral problems, especially those who are adopted at an older age. We took a new approach in our study of the network structure and predictability of emotional and behavioral problems in internationally adopted children in Finland. Our sample was from the on-going adoption study and comprised 778 internationally adopted children (387 boys and 391 girls, mean age 10.5 (SD 3.4) years). Networks were estimated using Gaussian graphical models and lasso regularization for all the children, and separately for those who were adopted at different ages. The results showed that anxiety/depressive symptoms, social problems, and aggressiveness were the most central symptom domains. Somatic symptoms were the least central and had the weakest effect on the other domains. Similarly, aggressiveness, social problems, and attention problems were high in terms of predictability (73-65%), whereas internalizing problems were relatively low (28-56%). There were clear but local age-group differences in network structure, symptom centrality, and predictability. According to our findings, network models provide important additional information about the centrality and predictability of specific symptom domains, and thus may facilitate targeted interventions among international adoptees.Peer reviewe
