Sensory feedback from muscles and peripheral sensors acts to initiate, tune or reshape motor activity according to the state of the body. Yet, sensory neurons often show low levels of activity even in the absence of sensory input. Here we examine the functional role of spontaneous low-frequency activity of such a sensory neuron. The anterior gastric receptor (AGR) is a muscle-tendon organ in th...

The UV polymerization process dictates the materials that can be employed in the sheath-flow device downstream from the hydrodynamic focusing grooves. The primary requirement for UV polymerization is an integrated window through which the shaped core can be polymerized using a UV source. Possible options include the use of all PDMS parts, top and bottom, or a combination of PDMS and silicon/gla...

The wood biomass was liquefied by the pressurized hydrothermal method. The wood biomass powder in the different particle size, which was pulverized by a vibration mill, cutter mill and grinder, was used for the liquefaction. The liquefaction material was biomass slurry, which was prepared by mixing the wood biomass powder and water together (1:9). After filling the biomass slurry in a pressure ...

A MOP has five key steps: team formation; baseline analysis; benchmarking; project definition; implementation, monitoring and feedback. In the MOP approach, technical and business intellect is substituted for capital and equipment. Baseline analysis provides the current performance, variation of key production and process elements, and provides the data for cause and effect analysis. A MOP look...

background and purpose: many workers are exposed to workplace hazards. many occupational diseases are preventable by personal protective devices (ppds). though many workers do not use ppds or their protection by ppds is not sufficient. this study was designed to assess the quality of ppds usage among industrial workers. materials and methods: in a cross-sectional study, 648 workers from four ma...

There’s an old saying in Washington DC — making laws is like making sausage; you’re better off not knowing the details. Well, that same spirit often applies to the coverage of science news. The focus is on the succulent final product rather than the process required to get there. But science journalists have found the need to take a break from that approach with one big biology story: the tale ...

The resonant circuit of the impedance transformed parametric ampli er (IMPA) is based on a previous experiment with lumped-element josephson parametric ampli ers (JPAs) coupled directly to a 50Ω environment [1]. This design is shown in Fig. S1, along with a circuit diagram for the device. The circuit consists of 5 separate layers of optical lithography as well as a nal e-beam lithography step t...

A series of devices have been investigated which use acoustic radiation forces to concentrate micron sized particles. These multi-layered resonators use a quarter-wavelength resonance in order to position an acoustic pressure node close to the top surface of a fluid layer such that particles migrate towards this surface. As flow-through devices, it is then possible to collect a concentrate of p...

Rhythmic motor patterns, which underlie behaviors such as mastication, respiration and locomotion, are generated by specialized neural circuits called central pattern generators (CPGs). Although CPGs can generate their rhythmic motor output in the absence of rhythmic input, these motor patterns are modified by rhythmic sensory feedback in vivo. Furthermore, although the importance of sensory fe...
