Abstract

The present disclosure relates to a method involving a substrate having an interface layer, wherein the interface layer (IL) forms only an upper surface portion of the substrate, and a feedstock material (FM) placed on the IL. The method involves using a laser system to generate first and second beam components providing first and second power flux levels, respectively, where the second power flux level which is greater than the first. The FM is heated to a first level short of a melting point using the first beam component, at which point the particles of the FM begin to experience surface tension forces relative to the IL. Further heating the FM to a second level melts the FM and also melts the IL of the substrate, but where a portion of the IL remains unmelted by the second beam component as the particles of the FM and the IL are bonded together. The method also involves configuring the laser system such that the second beam component has a duration less than the first beam component by a factor of at least 1×10−3, and a power controlled to be sufficient only to melt the interface layer of the substrate.

Abstract

A system for time series analysis using attention models is disclosed. The system may capture dependencies across different variables through input embedding and may map the order of a sample appearance to a randomized lookup table via positional encoding. The system may capture capturing dependencies within a single sequence through a self-attention mechanism and determine a range of dependency to consider for each position being analyzed. The system may obtain an attention weighting to other positions in the sequence through computation of an inner product and utilize the attention weighting to acquire a vector representation for a position and mask the sequence to enable causality. The system may employ a dense interpolation technique for encoding partial temporal ordering to obtain a single vector representation and a linear layer to obtain logits from the single vector representation. The system may use a type dependent final prediction layer.

Methods, devices and systems for ultra-high dose radiotherapy are described that rely in-part on active switching control of a photoconductive switch when the accelerator is accelerating charged particles to produce output radiation at desired dose rates. One example method for producing output radiation in a flash radiotherapy system includes receiving, at a particle accelerator, a charged particle beam, where the particle accelerator system also includes a photoconductive switch coupled to the particle accelerator. The photoconductive switch can operate in a linear mode and includes a doped crystalline material that receives a voltage to establish an electric field across the crystalline material. The method includes producing a plurality of voltage pulses by the photoconductive switch in response to receiving light incident on the doped crystalline material, and accelerating the charged particles by the particle accelerator based on the plurality of voltage pulses to produce the output radiation beams for flash radiotherapy.

Abstract

A system is provided for background suppression and anomaly detection/classification in a sensor data field using an omnidirectional stochastic technique to expose anomalies. For each element in the sensor data field, the system identifies neighborhoods of elements that cover the various nearby parts of the sensor data field in all directions. At a specified statistical significance level for background, the system considers the element to be background if it is statistically insignificant relative to the elements in any one of the surrounding neighborhoods. The system exposes anomalous objects by applying an attenuation coefficient near zero to those background elements. The system grows anomalous objects from seed elements that correspond to local peaks in the background-suppressed sensor data field. The system can be trained to jointly learn an effective statistical significance level for background suppression and the parameters for classifying objects as of interest or not of interest.

Abstract

Carbon nanotube (CNT) forests are grown directly on a base material for an anode. The CNTs are filled with Li metal. The filling behavior of the CNTs with Li metal is governed by the density, height, and diameter of the CNTs in the forest. These parameters are controlled by modifying the chemical vapor deposition (CVD) recipe used to grow the CNT forest along with adjusting the catalyst stack design to tune the aspect ratio, density, and rigidity of the CNT forest.

Abstract

The present disclosure relates to an apparatus for additively manufacturing a product in a layer-by-layer sequence, wherein the product is formed using powder particles deposited on an interface layer of a substrate. A laser generates first and second beam components. The second beam component has a higher power level and a shorter duration than the first beam component. A mask creates a 2D optical pattern in which only select portions of the second beam components can irradiate the powder particles. The first beam component heats the powder particles close to a melting point, where the particles experience surface tension forces relative to the interface layer. While the particles are heated, the second beam component further heats the particles and also melts the interface layer before the surface tension forces can act on and distort the particles, enabling the particles and the interface layer are able to bond together.
