PAD4 has been strongly implicated in the pathogenesis of autoimmune, cardiovascular and oncological diseases through clinical genetics and gene disruption in mice. New selective PAD4 inhibitors ...binding a calcium-deficient form of the PAD4 enzyme have validated the critical enzymatic role of human and mouse PAD4 in both histone citrullination and neutrophil extracellular trap formation for, to our knowledge, the first time. The therapeutic potential of PAD4 inhibitors can now be explored.
Barbara went on to affirm teaching as a developmental process, much more than mere learning of pedagogic tricks, and that there is so much benefit to such development being undertaken as inquiry in ...partnership with others, in particular with university colleagues.

In textbooks we see these definitions (figure 7): although the following interpretation of exterior angle is plausible in the light of the provided definition of interior angle (figure 8): I see one ...text proclaims, "This is not an exterior angle". In response to a task asking for the distance a ball is thrown and which is found from a quadratic equation with solutions -300 and 67, students who are aware that the negative value has to be ignored, sometimes write, "The distance is 67m. Learners may be told that a solution to a quadratic equation should not be written x = 3 and x = 2, on logical grounds, but as x = 3 or x = 2, as seen in the texts, although on the next line the text announces, "So the solutions are x = 3 and x = 2", returning from logical to everyday. Which of the subtleties and refinements can be deferred until later, without actually misleading, in order to make the broad ideas accessible to beginners? (p. 221) Perhaps Thornton has it about right, there is no single answer, decisions about everyday and mathematical classroom talk being, to turn a phrase, "horses for cases".

Ian Benson and Jim Thorpe report on the activities of the functional programming and computer algebra working group (FPCA). The Functional Programming and Computer Algebra (FPCA) Working Group brings ...together mathematics and computer science teachers, software developers, researchers and educationists to investigate the implications of ubiquitous computing for school mathematics. Statutory computer science is traditionally taught without programming ('unplugged'), by dragging and dropping code fragments (Scratch, Blockly) or with industry standard imperative languages (Python, P5·js).

How are we assessing learners' achievements and progress without the use of levels? - In what ways might the emphasis on fluency mean much more than rote learning, if we are to realise the other aims ...of problem solving, mathematical reasoning and conceptual understanding? - How do we enable learners to think mathematically, as an aspect of learning which pervades the entire curriculum? - How can we ensure a meaningful and rich experience of the additional content in the primary curriculum for example large numbers, algebra, ratio and proportion, Roman numerals? - What strategies are you using to ensure that statistical reasoning is developed through opportunities across the curriculum? - ...

This paper investigates the impact of different iron (Fe) buffer doping profiles on trapping effects in microwave AlGaN/gallium nitride (GaN) high electron mobility transistors (HEMTs). We ...characterize not only the current collapse due to trapping in the buffer, but also the recovery process, which is important in the analysis of suitable linearization schemes for amplitude modulated signals. It is shown that the simple pulsed dc measurements of current transients can be used to investigate transient effects in the RF power. Specifically, it is revealed that the design of the Fe-doping profile in the buffer greatly influences the recovery time, with the samples with lower Fe concentration showing slower recovery. In contrast, traditional indicators, such as S-parameters and dc as well as pulsed I-V characteristics, show very small differences. An analysis of the recovery shows that this effect is due to the presence of two different detrapping processes with the same activation energy (0.6 eV) but different time constants. For highly doped buffers, the faster process dominates, whereas the slower process is enhanced for less doped buffers.
