Perceptually smooth timbral guides by state-space analysis of phase-vocoder parameters
Sculptor is a phase-vocoder-based package of programs
that allows users to explore timbral manipulation
of sound in real time. It is the product
of a research program seeking ultimately to perform
gestural capture by analysis of the sound a
performer makes using a conventional instrument.
Since the phase-vocoder output is of high dimensionality —
typically more than 1,000 channels per
analysis frame—mapping phase-vocoder output to
appropriate input parameters for a synthesizer is
only feasible in theory
Antitrust Scrutiny of the Health Professions: Developing a Framework for Assessing Private Restraints
This Article has suggested that courts adopt an intermediate level of scrutiny, between per se and Rule of Reason analysis. Under this analysis, a rebuttable presumption of illegality attaches to those practices which in other contexts are per se illegal. The weight of this presumption varies with the familiarity of the court with the restraint, its similarity to traditional per se conduct, and the strength of the procompetitive justification.This analytical approach is desirable for two reasons. First,courts are reluctant to apply commercial per se rules of illegality to professional restraints, and with good reason. Professional practices do differ from purely commercial transactions. At the same time, however, some professionals do engage in highly anticompetitive practices. Courts ought to have a test for assessing these practices that is less cumbersome than full-blown Rule of Reason analysis. Second, a truly competitive market for health services will provide better assurance of high quality care and reasonable prices than a market controlled by dominant professional groups. Competition will create incentives for providers and insurers to disseminate more information to consumers--information about prices, availability, billing procedures, and provider qualifications. Also,competition may encourage development of alternative forms of delivering services, particularly those that have the potential for increasing efficiency and reducing costs. By focusing on the procompetitive effects of professionally imposed restraints, courts will be able to review objectively both the economic and social consequences of the challenged activity. An intermediate level of review is not a radical departure from existing case law. Nevertheless, recognizing that it exists and spelling out how it should be conducted is important for the further development of the law in this area

Magnetic actuation of microparticles for mass transfer enhancement
This paper was presented at the 4th Micro and Nano Flows Conference (MNF2014), which was held at University College, London, UK. The conference was organised by Brunel University and supported by the Italian Union of Thermofluiddynamics, IPEM, the Process Intensification Network, the Institution of Mechanical Engineers, the Heat Transfer Society, HEXAG - the Heat Exchange Action Group, and the Energy Institute, ASME Press, LCN London Centre for Nanotechnology, UCL University College London, UCL Engineering, the International NanoScience Community, www.nanopaprika.eu.The motion of magnetic microparticles (250ÎĽm diameter) in a circular microfluidic reactor with a diameter of 10 mm under time dependent magnetic field has been studied using CFD code COMSOL. The effect of actuation protocol on the local and average particle velocity has been investigated. The local Sh numbers were obtained as a function of angular particle position in the range of Re numbers between 0.05 and 10 while the particle velocity was changed over two orders of magnitude. Under time dependent magnetic field, the thickness of the boundary layer continuously changes which results in an increased mass transfer towards the particle surface under periodic particle velocity conditions as compared to steady state velocity conditions. A good agreement between numerical and experimental data has been observed
Rich Situated Attitudes
We outline a novel theory of natural language meaning, Rich
Situated Semantics [RSS], on which the content of sentential utterances
is semantically rich and informationally situated. In virtue of its situatedness,
an utterance’s rich situated content varies with the informational
situation of the cognitive agent interpreting the utterance. In virtue of its
richness, this content contains information beyond the utterance’s lexically
encoded information. The agent-dependence of rich situated content
solves a number of problems in semantics and the philosophy of language
(cf. [14, 20, 25]). In particular, since RSS varies the granularity of utterance
contents with the interpreting agent’s informational situation, it
solves the problem of finding suitably fine- or coarse-grained objects for
the content of propositional attitudes. In virtue of this variation, a layman
will reason with more propositions than an expert
Structural Polymorphism of the Cytoskeleton: A Model of Linker-Assisted Filament Aggregation
The phase behavior of charged rods in the presence of inter-rod linkers is
studied theoretically as a model for the equilibrium behavior underlying the
organization of actin filaments by linker proteins in the cytoskeleton. The
presence of linkers in the solution modifies the effective inter-rod
interaction and can lead to inter-filament attraction. Depending on the
system's composition and physical properties such as linker binding energies,
filaments will either orient perpendicular or parallel to each other, leading
to network-like or bundled structures. We show that such a system can have one
of three generic phase diagrams, one dominated by bundles, another by networks,
and the third containing both bundle and network-like phases. The first two
diagrams can be found over a wide range of interaction energies, while the
third occurs only for a narrow range. These results provide theoretical
understanding of the classification of linker proteins as bundling proteins or
crosslinking proteins. In addition, they suggest possible mechanisms by which
the cell may control cytoskeletal morphology.Comment: 17 pages, 3 figure

Vivaldi 1991 - A study of the formation, circulation and ventilation of Eastern North Atlantic Central Water
31 páginas, 10 figuras, 1 tablaA synoptic, hydrographic data set comprising 32 full depth CTD casts and 2500
CTD/SeaSoar profiles to 500 m is used to describe the 0/S properties and circulation of Central
Water east of the mid-Atlantic Ridge and between 39°N and 54°N. Eastward transport of 20 x
10 ~ m 3 s l in the North Atlantic Current turns entirely northwards to the west of 54°N, 20°W.
This transport consists in the upper layers of Western North Atlantic Water freshened at
temperatures below 10°C by mixing with SubArctic Intermediate Water. Northern and
Southern branches of the North Atlantic Current are well defined and both turn northwards west
of 20°W. A further l0 x l0 s m 3 s "1 of Eastern North Atlantic Water forms and recirculates
anticyclonicaily to the west of Spain south of the North Atlantic Current and north of 40°N.
Eastern North Atlantic Water is most weakly stratified east of 20°W and there is clear
correlation between weakly stratified pycnostads and positive salinity anomalies relative to
Western North Atlantic Water. Thus Eastern North Atlantic Water is a winter Mode Water in
which strong winter cooling has increased the density and hence also the salinity anomaly at
a given temperature. Near the southern entrance to the Rockall Trough there is evidence that
salinities are also increased by Mediterranean Water influence. Circulation south of the North
Atlantic Current is complex. There is no evidence for direct ventilation southwards across 40°N
where water properties (0/S, potential vorticity and CFC-113) and historical data all indicate
westward ventilation east of 24°W, with weak southward ventilation occurring further west, in
the vicinity of the Azores. The circulation pattern suggested is remarkably similar to that
proposed by Helland-Hansen and Nansen in 1926 (The eastern North Atlantic, Geophysiske
Publicajoner, 4, 1-76), with anticyclonic circulation of colder Eastern North Atlantic Water
north of 40°N meeting warmer water from south of 40°N circulating cyclonically north of the
Azores Current. The distribution of pycnostads and 0IS properties between 20°W and 35°W
north of the Azores indicates alternate bands of Western and Eastern North Atlantic Water
moving eastward and westward respectively, including evidence for westward motion immediately
south of the Southern branch of the North Atlantic Current, possibly by westward propagation of
anticyclonic eddies containing deep pycnostadsPeer reviewe
A Qualitative Exploration of Using Experiential Groups to Train Future Group Counselors
As counselors routinely provide both individual and group-based services, it is important to prepare trainees to effectively utilize both approaches. One popular method for engaging students in group work training requires them to participate in experiential small groups. Although this requirement meets CACREP’s (2015) standard that students engage in 10 hours of group membership, less specific focus is placed on engaging students in active group facilitation training. This study analyzes qualitative interviews with seven counseling graduates who participated in experiential small groups during their training. Five emergent themes provide insight for counselor educators and accreditors into students’ group training experiences
