Darrin Patrick’s Death, His Love for Pastors, and How We Need One Another

Darrin’s death is not the last word on his life. His love for pastors—and his concern for their mental health and thriving—can be part of our response today.

Darrin Patrick has died.

Darrin is probably best known for planting The Journey Church in St. Louis in 2002, eventually growing to six locations. He was a husband, father, speaker, and author.

Darrin and his spiritual mentor Greg Surratt led the Pastor's Collective podcast and he was serving as a teaching pastor at Seacoast Church.

But, most importantly, Darrin was married to Amie and they have four children.

Darrin’s Journey and Focus

Darrin was very open about his journey—and specifically asked me to help share his story a little over a year ago. His story of leaving the Journey is painful and messy, but he wanted people to know about it.

He wanted people to learn from his pain.

Darrin died from a “self-inflicted gunshot wound.” I know that has caused some people to want more details—to use language that is more precise and to provide added details. And, as you can tell from the statement, the situation is confusing. Seacoast Church shared, ““Darrin was target shooting with a friend at the time of his death. An official cause of death has not been released but it appears to be a self-inflicted gunshot wound. No foul play is suspected.”

Thus, it is important to let families communicate the way they are comfortable. Families grieve in complex ways—and right now, they owe nothing to the rest of us. We just owe them our prayers.

The family is grieving and I am respecting their grief and their communication choices.

And, from there, I am going to take Darrin’s admonition from a year ago and fast forward it until now—hoping that even this moment might be a catalyst for pastors to get help that Darrin always wanted them to get.

Darrin and I talked recently and his last ...

Generating three-color pulses in high-gain harmonic-generation free-electron lasers with a tilted electron bunch

A multi-color light source is a significant tool for nonlinear optics experiments, pump–dump/repump–probe experiments and in other fields. Here, a novel method is proposed to create three-color pulses based on a high-gain harmonic-generation (HGHG) free-electron laser with a tilted electron bunch. In this method, the initial bunch tilt is created by transverse wakefields after the bunch passes through a corrugated structure with an off-axis orbit, and is further enlarged in a following drift section. Then the tilted bunch experiences the off-axis field of a quadrupole magnet to cool down the large transverse velocity induced before. After that, it enters an HGHG configuration adopting a transverse gradient undulator (TGU) as the radiator, where only three separated fractions of the tilted bunch will resonate at three adjacent harmonics of the seed wavelength and are enabled to emit three-color pulses simultaneously. In addition, the use of the natural transverse gradient of a normal planar undulator instead of the TGU radiator to emit three-color pulses is also studied in detail. Numerical simulations including the generation of the tilted bunch and the free-electron laser radiation confirm the validity and feasibility of this scheme both for the TGU radiator and the natural gradient in the extreme-ultraviolet waveband.

X-ray free-electron laser wavefront sensing using the fractional Talbot effect

Wavefront sensing at X-ray free-electron lasers is important for quantitatively understanding the fundamental properties of the laser, for aligning X-ray instruments and for conducting scientific experimental analysis. A fractional Talbot wavefront sensor has been developed. This wavefront sensor enables measurements over a wide range of energies, as is common on X-ray instruments, with simplified mechanical requirements and is compatible with the high average power pulses expected in upcoming X-ray free-electron laser upgrades. Single-shot measurements were performed at 500 eV, 1000 eV and 1500 eV at the Linac Coherent Light Source. These measurements were applied to study both mirror alignment and the effects of undulator tapering schemes on source properties. The beamline focal plane position was tracked to an uncertainty of 0.12 mm, and the source location for various undulator tapering schemes to an uncertainty of 1 m, demonstrating excellent sensitivity. These findings pave the way to use the fractional Talbot wavefront sensor as a routine, robust and sensitive tool at X-ray free-electron lasers as well as other high-brightness X-ray sources.

Limited angle tomography for transmission X-ray microscopy using deep learning

In transmission X-ray microscopy (TXM) systems, the rotation of a scanned sample might be restricted to a limited angular range to avoid collision with other system parts or high attenuation at certain tilting angles. Image reconstruction from such limited angle data suffers from artifacts because of missing data. In this work, deep learning is applied to limited angle reconstruction in TXMs for the first time. With the challenge to obtain sufficient real data for training, training a deep neural network from synthetic data is investigated. In particular, U-Net, the state-of-the-art neural network in biomedical imaging, is trained from synthetic ellipsoid data and multi-category data to reduce artifacts in filtered back-projection (FBP) reconstruction images. The proposed method is evaluated on synthetic data and real scanned chlorella data in 100° limited angle tomography. For synthetic test data, U-Net significantly reduces the root-mean-square error (RMSE) from 2.55 × 10−3 µm−1 in the FBP reconstruction to 1.21 × 10−3 µm−1 in the U-Net reconstruction and also improves the structural similarity (SSIM) index from 0.625 to 0.920. With penalized weighted least-square denoising of measured projections, the RMSE and SSIM are further improved to 1.16 × 10−3 µm−1 and 0.932, respectively. For real test data, the proposed method remarkably improves the 3D visualization of the subcellular structures in the chlorella cell, which indicates its important value for nanoscale imaging in biology, nanoscience and materials science.
