A Domain-Independent Algorithm for Plan Adaptation
The paradigms of transformational planning, case-based planning, and plan
debugging all involve a process known as plan adaptation - modifying or
repairing an old plan so it solves a new problem. In this paper we provide a
domain-independent algorithm for plan adaptation, demonstrate that it is sound,
complete, and systematic, and compare it to other adaptation algorithms in the
literature. Our approach is based on a view of planning as searching a graph of
partial plans. Generative planning starts at the graph's root and moves from
node to node using plan-refinement operators. In planning by adaptation, a
library plan - an arbitrary node in the plan graph - is the starting point for
the search, and the plan-adaptation algorithm can apply both the same
refinement operators available to a generative planner and can also retract
constraints and steps from the plan. Our algorithm's completeness ensures that
the adaptation algorithm will eventually search the entire graph and its
systematicity ensures that it will do so without redundantly searching any
parts of the graph.Comment: See http://www.jair.org/ for any accompanying file
Boundary Spanning in Academia: Antecedents and Near-Term Consequences of Academic Entrepreneurialism
Analyzing the pathways of people who earned interdisciplinary research doctorates in the United States in 2010, we generate three main findings while controlling for gender, ethnicity, discipline, and age. First, individuals who complete an interdisciplinary dissertation display near-term income risk since they tend to earn nearly $1,700 less in the year after graduation. Second, students whose fathers earned a college degree demonstrated a .8% higher probability of pursuing interdisciplinary research. Third, the probability that non-citizens pursue interdisciplinary dissertation work is 4.7% higher when compared with US citizens. Our findings quantify the risks of interdisciplinary work and contribute to policy debates
Khaos Company
Khaos Company offers a short story written with the intent to provide Marines with the perspective of what it is like to operate and fight at the company- and small-unit levels in operations of such a large scale and scope. This is a story about how a small yet cohesive company of Marines experienced chaos, friction, uncertainty, surprise, failure, success, relationships, and executed the maneuver warfare principles outlined in the Marine Corps’ doctrinal warfighting philosophy

Biochemical and Morphological Studies of Rat Submandibular Gland: III. Effects of Testosterone Treatment on Proteins of Granule-Rich Fraction
Mature adult male rats and castrated and testosterone-treated castrated adult rats were injected with pilocarpine HGL and 3-H-lysine and sacrificed sequentially over an eight-hour time period. Following homogenization and differential centrifugation, three subcellular fractions from each group of animals were analyzed by gel electrophoresis and liquid scintillation. Two proteins in the granule-rich fraction appeared in larger amounts on the densitometric scans and appeared to represent a larger proportion of newly synthesized proteins than the other proteins.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/66712/2/10.1177_00220345770560030901.pd

Coherent Control of Causal Order of Entanglement Distillation
We present an application of indefinite causal order in quantum
communication: a compound entanglement distillation protocol which features two
steps of a basic distillation protocol applied in a coherent superposition of
two causal orders. This is achieved by using one faulty entangled pair to
control-swap two others before a fourth pair is combined with the two swapped
ones consecutively. As a result, the protocol distills the four faulty
entangled states into one of a higher fidelity. Our protocol has a higher
fidelity of distillation and probability of success for some input faulty pairs
than conventional concatenations of the basic protocol that follow a definite
distillation order. Our proposal shows advantage of indefinite causal order in
an application setting consistent with the requirements of quantum
communication
Noise-tailored Constructions for Spin Wigner Function Kernels
The effective use of noisy intermediate-scale quantum devices requires error
mitigation to improve the accuracy of sampled measurement distributions. The
more accurately the effects of noise on these distributions can be modeled, the
more closely error mitigation will be able to approach theoretical bounds. The
characterisation of noisy quantum channels and the inference of their effects
on general observables are challenging problems, but in many cases a change in
representation can greatly simplify the analysis. Here, we investigate spin
Wigner functions for multi-qudit systems. We generalise previous kernel
constructions, capturing the effects of several probabilistic unitary noise
models in few parameters
