Commutativity and Ideals in Category Crossed Products
In order to simultaneously generalize matrix rings and group graded crossed products, we introduce category crossed products. For such algebras we describe the center and the commutant of the coefficient ring. We also investigate the connection between on the one hand maximal commutativity of the coefficient ring and on the other hand nonemptyness of intersections of the coefficient ring by nonzer
Structural Study of the Photo-Mediated Growth of Silver Nanoprisms
We present a small-angle X-ray scattering (SAXS) study of the anisotropic photoinduced growth of silver (Ag) nanoprisms in aqueous dispersions. The growth of nearly spherical (<10 nm) Ag particles into large (>40 nm) and thin (<10 nm) triangular nanoprisms induced by 550 nm laser is followed in terms of particle size using indirect and direct methods for irradiation times up to 150 min. During the
Transparency, consent and trust in the use of customers' data by an online genetic testing company : an Exploratory survey among 23andMe users
23andMe not only sells genetic testing but also uses customer data in its R&D activities and commercial partnerships. This raises questions about transparency and informed consent. Based on a online survey conducted in 2017–18, we examine attitudes of 368 customers of 23andMe toward the company's use of their data. Our findings point at divides in the context of customers' awareness of the two
Members of the public in the USA, UK, Canada and Australia expressing genetic exceptionalism say they are more willing to donate genomic data
Public acceptance is critical for sharing of genomic data at scale. This paper examines how acceptance of data sharing pertains to the perceived similarities and differences between DNA and other forms of personal data. It explores the perceptions of representative publics from the USA, Canada, the UK and Australia (n = 8967) towards the donation of DNA and health data. Fifty-two percent of this p
«Genethics» and public health genomics
In this chapter, we first reflect on approaches to public health, ethical positions on public health issues, and definitions of health. We subsequently present ethical, legal, and social issues in genetics and genomics, with particular attention to public health and the historical perspective. We then discuss the issues related to the implementation of genomic technologies in public health with fo
Adsorption of 3-(triethoxysilyl)propionitrile on a rutile TiO2(110) surface : An X-ray photoelectron spectroscopy study
The adsorption of 3-(triethoxysilyl)propionitrile (TESP) on a reduced rutile TiO2(110) surface has been investigated using synchrotron-based X-ray photoelectron spectroscopy in ultrahigh vacuum (UHV). We have studied TESP adsorption on two surface preparation of rutile TiO2 (110) to explore the role of surface defects. In the first preparation, the adsorption of TESP was studied on reduced TiO2 (1
Consenting patients to genome sequencing
Obtaining informed consent for a medical intervention or testing is considered as one of the cornerstone principles in responsible medical practice, including in genetic and genomic clinical testing. The challenges of obtaining truly informed consent in this field have kept stakeholders particularly busy (if not weary) in the face of multidimensional (communication) obstacles which include: the un
How do consent forms for diagnostic high-throughput sequencing address unsolicited and secondary findings? A content analysis
Whole exome and whole genome sequencing are increasingly being offered to patients in the clinical setting. Yet, the question of whether, and to what extent, unsolicited findings (UF) and/or secondary findings (SF) should be returned to patients remains open and little is known about how diagnostic consent forms address this issue. We systematically identified consent forms for diagnostic genomic
Attitudes of publics who are unwilling to donate DNA data for research
With the use of genetic technology, researchers have the potential to inform medical diagnoses and treatment in actionable ways. Accurate variant interpretation is a necessary condition for the utility of genetic technology to unfold. This relies on the ability to access large genomic datasets so that comparisons can be made between variants of interest. This can only be successful if DNA and medi

Trust in genomic data sharing among members of the general public in the UK, USA, Canada and Australia
Trust may be important in shaping public attitudes to genetics and intentions to participate in genomics research and big data initiatives. As such, we examined trust in data sharing among the general public. A cross-sectional online survey collected responses from representative publics in the USA, Canada, UK and Australia (n = 8967). Participants were most likely to trust their medical doctor an
Analysis of VUS reporting, variant reinterpretation and recontact policies in clinical genomic sequencing consent forms
There are several key unsolved issues relating to the clinical use of next generation sequencing, such as: should laboratories report variants of uncertain significance (VUS) to clinicians and/or patients? Should they reinterpret VUS in response to growing knowledge in the field? And should patients be recontacted regarding such results? We systematically analyzed 58 consent forms in English used
Engineered MSW landfills as a future material resource and a sink for long-term storage of organic carbon
A controlled, highly engineered landfill has many similarities to natural peatlands or other natural anoxic sediment deposits. In anaerobic MSW landfills, generally about 30-50 percent of the total carbon content in the waste can be converted into biogas and be collected as resource for energy or chemical industry. Remaining long-lived organic carbon, e.g. from lignin remains un-degraded, Organic
Current Ethical Issues Related to the Implementation of Whole-Exome and Whole-Genome Sequencing
We have briefly discussed herein four of the many aspects that raise concerns in the context of implementation of whole-exome and whole-genome sequencing (mainly) in the clinical realm. Namely, we addressed issues surrounding: (1) the duty to hunt for variants known to have a health impact, (2) such “hunting” or opportunistic screening in children, (3) challenges to the consent process, and (4) th
Concentration-and pH-dependent oligomerization of the thrombin-derived C-terminal peptide TCP-25
Peptide oligomerization dynamics affects peptide structure, activity, and pharmacodynamic properties. The thrombin C-terminal peptide, TCP-25 (GKYGFYTHVFRLKKWIQKVIDQFGE), is currently in preclinical development for improved wound healing and infection prevention. It exhibits turbidity when formulated at pH 7.4, particularly at concentrations of 0.3 mM or more. We used biochemical and biophysical a

Principles and Patterns of JastAdd-Style Reference Attribute Grammars
Reference attribute grammars (RAGs) have reached a level of maturity where they are supported by several tools, and have gained traction in both academic and industrial language tool development. However, despite a lot of accumulated knowledge of how to best develop RAGs in practice, there is limited support to guide practitioners.In this paper, we address this issue by focusing on one RAG tool, J
