Abstract:

Vertebrate kinetochores contain over 50 different proteins organized into three distinct regions: the inner plate, outer plate, and fibrous corona. The present study characterizes numerous precursors of kinetochore assembly in a system free of centromeric chromatin, Xenopus extracts. Hydrodynamic analysis suggests there are a minimum of two monomeric proteins and six preassembled complexes that accumulate on centromeres to form the kinetochore. The inner and outer kinetochore assemble from at least two distinct kinetochore complexes containing the proteins Mis12, Zwint, and Ndc80, all of which

Abstract:

In this paper, we firstly present a classification framework of assembly systems. Then, models of such assembly systems structures are divided into classes on the basis of the numbers of initial components to be assembled. Subsequently, selected scenarios for measuring a structural complexity of assembly systems structures based on demand are employed. Finally, a relationship between complexity and usability is analyzed and future research is recommended.

Abstract:

Standard impact noise insulation testing is based on measuring the average sound level in a reverberant field in order to estimate the incident and/or radiated sound power. While this method is straightforward, the variation under reproducibility conditions is significant, and a significant portion of the uncertainty is due to the complications of measuring the sound field in the receiving space. This variation is largest at low frequencies, where the effects of spatial variation and modes in the receiving room are well documented.

Abstract Active galactic nuclei (AGNs) are promising environments for the assembly of merging binary black hole (BBH) systems. Interest in AGNs as nurseries for merging BBHs is rising, following the detection of gravitational waves from a BBH system from the purported pair-instability mass gap, most notably GW190521. AGNs have also been invoked to explain the formation of the high-mass-ratio system GW190814. We draw on simulations of BBH systems in AGNs to propose a phenomenological model for the distribution of black hole spins of merging binaries in AGN disks. The model incorporates distinct

Electromagnetic actors (solenoids) are used in automotive and automation technology as valve actors for pneumatics and hydraulics or as actuating and pressure solenoids. During assembly there are often press-in and caulking processes used. A central quality aspect of the final control elements is the adherence to defined actuating force ranges in order to ensure the switching process and at the same time to keep wear within limits. These defined force ranges can currently only be maintained by additional heat treatment of the parts. The hysteresis of the assembled unit can be influenced by the

To do this, eukaryotic cells employ an arsenal of regulatory proteins to control microtubule dynamics spatially and tempo

Abstract:

The standard tapping machine used for the ASTM and ISO tests does not require the test engineer to measure the input force in the system, instead, just relies on measuring the sound pressure level (SPL) output. However, the input force depends on the assembly itself being tested. The input force levels are lower for lightweight assemblies like hardwood floors as compared to heavyweight assemblies like concrete. Without knowledge of this input force, the output SPL levels cannot and should not be compared using the IIC (Impact Insulation Class) rating. In this work, we measured the input force

Abstract:

In this paper, the authors present the design of an experimental device for measuring small flow rates of gaseous media. For the design and construction, materials were used to create a local pressure resistance and thus allow the pressure gradient to be measured upstream and downstream of the measuring element. The proposed measuring devices can serve as an alternative to actual measuring devices for detecting the instantaneous quantity flowing in the measuring assembly. The results obtained from the experimental measurements are used to determine the characteristics of the proposed measuring

Abstract:

The basic principle of the hydrogen storage alloy PCT (Pressure-Composition-Temperature) measuring apparatus is introduced in this article. And the method of 3D virtual design in the hydrogen storage alloy PCT measuring apparatus based on SolidWorks software is described. The conceptual design of the system is conducted by Visio software. And the design, assembly, commissioning and optimization of parts is conducted by SolidWorks and the valve, gas piping, sample room, measuring apparatus are improved. Eventually it is found that the reliability and development efficiency of the measuring syst

Abstract:

The effect of the tooth contact and alignment error of the hypoid gear assembly on transmission error was investigated with a new measuring apparatus which can measure the transmission errors of loaded hypoid gears assembled into a final drive unit. Measurements indicate that transmission error predictions made with the TCA and LTCA — analytical tools developed by Gleason Works for a no-load and loaded state, respectively — have sufficient accuracy when actual data on the gear tooth surface and alignment error of the gear assembly are used in the calculations. A systematic examination has also

This paper addresses the development of an image analysis technique using the Fourier transform of the image to evaluate orientation in a fibrous assembly. The algorithms are evaluated using simulated images presented in Part I of the series. The results are compared with those for the tracking method presented in Part II.

Abstract:

The shaft hoist assembly is the base of underground mining plant. Its efficiency and correct operation is subject to restrictive legal regulations and is controlled on a daily visual assessment by shaft crew and energomechanics. In addition, in the regular interval, the shaft hoist assembly is subject to a thorough inventory, which includes the determination of the geometrical relationships between the hoisting machine, the headframe and the shaft with its housing. Inventory measurements for shaft and headframe are used for years of conventional geodetic methods including mechanical or laser p

Abstract:

Engineering formulas are presented for calculating the value of methodological error in measuring the distances from the ultrasonic sensor to the surface of the irradiated fuel assembly of WWER-1000 caused by decay heat from the fuel assembly. The methodical error arises due to the water temperature gradient along ultrasonic wave path. This is due to the presence of natural convection at the surface of the fuel assembly discharged from the reactor into cooling pool at nuclear power plant. The paper presents a methodology for calculating the methodical error. It is assumed that the water temper

Evaluation method of assembly yield in three-dimension single-station assembly process is presented based on Number-Theoretical Net (NT-net) and 3DCS. Firstly, based on the analysis of fixture deviation affect assembly deviation under arbitrary layout, the three dimensional single-station assembly deviation model under arbitrary layout is developed. Then, the principle of generating good lattice point (GLP) based on NT-net method is introduced. Afterwards, taking fixture locating variations which are sampled using NT-net method for input vectors, the samples are substituted into assembly devia

Abstract:

Protein-protein interactions at the cell surface are important in the activity of bacterial toxins such as colicins. We have developed methods to study these events using tethered lipid bilayers, which can be probed by impedance spectroscopy and surface plasmon resonance. Recently we have attached the receptor proteins directly to gold electrodes and this offers new possibilities for measuring protein-protein interactions on solid supports.
