Water stories told in Kilimanjaro Region, such as Mami Wata narratives conveyed across Africa and the Atlantic, give horrific insights into morally problematic forms of wealth acquisition through environmental destruction. This paper approaches farmers’ water spirits management practices indices witness to their own social displacement by government-backed agribusinesses. Analysis shows that fa...

In this paper, we show that the unsoundness discovered by Amin and Tate (2016) in Java’s wildcards is avoidable, even absence of a nullness-aware type system. The key insight paper soundness systems implicitly introduce existential types through subtyping hinges on still making sure there are suitable witness when introducing existentially quantified variables. To approach viable, formalizes co...

one of unsolved problems in quantum measurement theory is to characterize coexistence of quantum effects. in this paper, applying positive operator matrix theory, we give a mathematical characterization of the witness set of coexistence of quantum effects and obtain a series of properties of coexistence. we also devote to characterizing bijective morphisms on quantum effects leaving the witness...

In this paper, we investigate a corrugated mm-scale capillary as a compact accelerating structure in a drive – witness acceleration scheme, and suggest a methodology to measure acceleration of a witness bunch. Two typical measurements and the energy gain in a witness bunch as a function of the distance between bunches are discussed. A corrugated capillary is considered as an accelerator/deceler...

Neurologists have professional, ethical, and social obligations to ensure that expert witness testimony is reliable, objective, and truthful. In the past, an absence of professional regulatory oversight combined with immunity from civil litigation allowed the partisan expert to flourish. This is no longer the case. The expert witness unquestionably faces an increasingly perilous liability clima...

Edge states lying at the edge of PPT entangled states have a very intriguing existence and their detection is equally interesting. We present here a new witness for detection of edge states. We then compare between our proposed witness operator and the witness operator proposed in [Physical Review A, 62, 052310 (2000)] in terms of the efficiency in the detection of PPT entangled states. In this...
