Segmentation of extracellular microelectrode recordings with equal power

In this article we consider a problem of reliable modeling of echo signals and angle noise of distributed objects using twodimensional geometric models with random statistically unrelated signals. The conditions that ensure the invariance of distribution parameters of the angle noise generated by an arbitrary N-point configuration of a two-dimensional geometric model are obtained. In the particular case of a model whose emitters are supplied with signals of equal power, the conditions of invariance are reduced to the location of the model points on the plane in the form of a regular polygon. These results can be used to synthesize mathematical models used for simulating reflections from distributed objects and for developing a hardware-software complex for the simulation of electromagnetic fields reflected from the Earth surface, atmospheric inhomogeneities, the sea surface, etc.

Critical Aspects

Two commonly articulated goals of engaged anthropology include: 1) creating equal power relations with research participants; and 2) producing scholarship that critiques inequality. Though these seem commensurate, this article discusses how working toward both goals can lead to conflict when collaborators vehemently disagree with the critical aspects of your research findings. This article argues that writing about the ethnographic backstage — the background negotiations that rarely make it to the printed page — can help engaged anthropologists foster more egalitarian relations when it comes to ethnographic representation and can sharpen our sociocultural critiques. Because engaged anthropology, by definition, is shaped by negotiations with research participants, examining the ethnographic backstage helps us better understand an important axis in the production of anthropological knowledge.

AbstractIn this paper, a tunable balanced-to-balanced in-phase filtering power divider (FPD) is designed, which can realize a two-way equal power division with high selectivity and isolation. A differential-mode (DM) passband with a steep filtering performance is realized by applying microstrip stub-loaded resonators (SLRs). Meanwhile, six varactors are loaded to the SLRs to achieve the center frequency (CF) and bandwidth adjustment, respectively. U-type microstrip lines integrated with stepped impedance slotline resonators are utilized as the differential feedlines, which suppress the common-mode (CM) intrinsically, making the DM responses independent of the CM ones. A tuning center frequency from 3.2 to 3.75 GHz and a fractional bandwidth (12.1–17.6%) with more than 10 dB return loss and less than 2.3 dB insertion loss can be achieved by changing the voltage across the varactors. A good agreement between the simulated and measured results is observed. To the best of authors' knowledge, the proposed balanced-to-balanced tunable FPD is first ever reported.

In this paper, we advocate a collaborative approach to investigating past human–environment interactions in southwest Madagascar. We do so by critically reflecting as a team on the development of the Morombe Archaeological Project, initiated in 2011 as a collaboration between an American archaeologist and the Vezo communities of the Velondriake Marine Protected Area. Our objectives are to assess our trajectory in building collaborative partnerships with diverse local, indigenous, and descendent communities and to provide concrete suggestions for the development of new collaborative projects in environmental archaeology. Through our Madagascar case study, we argue that contemporary environmental and economic challenges create an urgency to articulate and practice an inclusive environmental archaeology, and we propose that environmental archaeologists must make particular efforts to include local, indigenous, and descendent communities. Finally, we assert that full collaboration involves equal power sharing and mutual knowledge exchange and suggest an approach for critical self-evaluation of collaborative projects.
