A global manufacturer of a broad line of electronic interconnect solutions worked with us to dispense conductive adhesive EpoTek H20E-FC. EpoTek H20E-FC is a two-component, electrically conductive, snap curing epoxy for photovoltaic thin film module stringing, semiconductor packaging and PCB circuit assembly. The primary goal was filling a rectangular cavity on a connector. The epoxy needed to fill the connector to the top of the walls in less than three seconds.

One of our defense customers planned to dispense underfill material for small and large die, using Hysol FP4545FC epoxy encapsulant. This process dissipates stress on solder joints and prevents cracking and fracturing between the bottom of the die and the surface of the substrate.

In electronics manufacturing, 'Underfill' refers to a material that is applied to fill the gap between a semiconductor device, such as flip-chip assemblies, Ball Grid Arrays (BGA), or Chip Scale Packages (CSP), and the substrate, such as a PCB or flex circuit.

The rat lungworm, Angiostrongylus cantonensis, is an emerging veterinary and public health concern. We describe A. cantonensis infections in a zoo-housed parma wallaby and free-ranging Virginia opossums and roof rats in San Diego, California, USA. Angiostrongyliasis should be considered in central nervous system disease in humans and animals in this region.

The Tintina fault is a major ∼1,000‐km‐long geologic fault in the Yukon Territory of northwestern Canada, previously believed to have last been active around 40 million years ago, but speculated to remain capable of generating large earthquakes. Using new high‐resolution topographic data collected from satellites, airplanes, and drones, we have identified a 130‐km‐long segment of the fault where 2.6 million‐year‐old, and 132 thousand‐year‐old geological formations are laterally shifted across the fault by ∼1,000 and 75 m, respectively. From this, we surmise that the Tintina fault has ruptured in numerous large earthquakes in the recent geologic past, and continues to accumulate strain at an average rate of 0.2–0.8 mm/yr. We further show that the fault has not ruptured in a major earthquake for at least 12 thousand years, and could generate an earthquake of at least magnitude 7.5 in the future. The Tintina fault therefore represents an important, previously unrecognized, seismic hazard to the region.

Color quantization is an image processing operation that attempts to reduce the number of distinct colors used to represent an image without significant loss of quality. This operation is useful as an initial step to perform further processing on the image. The interest in this operation has led to several solution methods being proposed over the years. Within these methods several swarm-based methods have been used in recent years to solve the problem. This article discusses the application of one of these methods, called grey wolf optimization, to perform color quantization. This algorithm has generated good results when applied to a variety of optimization problems. Among the features that differentiate this algorithm from other swarm algorithms are its ability to converge toward better solutions, its speed, and the existence of a single control parameter. The article describes in detail how the grey wolf optimization method should be adapted to perform color quantization, so that it generates a quantized palette that allows the quantized image to be represented. In this case, each individual in the group represents a quantized palette, which is improved with the information provided by the group. The detailed description of the algorithm is complemented by an extensive testing section that compares the results of the proposed method to those of 16 others techniques. The results, based on the comparison of MSE, MAE, PSNR, SSIM, and runtime, show that grey wolf optimization can generate good quality images, better than most of the compared methods.
