Modelling dynamical 3D electron diffraction intensities. I. A scattering cluster algorithm

Three-dimensional electron diffraction (3D-ED) is a powerful technique for crystallographic characterization of nanometre-sized crystals that are too small for X-ray diffraction. For accurate crystal structure refinement, however, it is important that the Bragg diffracted intensities are treated dynamically. Bloch wave simulations are often used in 3D-ED, but can be computationally expensive for large unit cell crystals due to the large number of diffracted beams. Proposed here is an alternative method, the `scattering cluster algorithm' (SCA), that replaces the eigen-decomposition operation in Bloch waves with a simpler matrix multiplication. The underlying principle of SCA is that the intensity of a given Bragg reflection is largely determined by intensity transfer (i.e. `scattering') from a cluster of neighbouring diffracted beams. However, the penalty for using matrix multiplication is that the sample must be divided into a series of thin slices and the diffracted beams calculated iteratively, similar to the multislice approach. Therefore, SCA is more suitable for thin specimens. The accuracy and speed of SCA are demonstrated on tri-iso­propyl silane (TIPS) pentacene and rubrene, two exemplar organic materials with large unit cells.

Modelling dynamical 3D electron diffraction intensities. II. The role of inelastic scattering

The strong interaction of high-energy electrons with a crystal results in both dynamical elastic scattering and inelastic events, particularly phonon and plasmon excitation, which have relatively large cross sections. For accurate crystal structure refinement it is therefore important to uncover the impact of inelastic scattering on the Bragg beam intensities. Here a combined Bloch wave–Monte Carlo method is used to simulate phonon and plasmon scattering in crystals. The simulated thermal and plasmon diffuse scattering are consistent with experimental results. The simulations also confirm the empirical observation of a weaker unscattered beam intensity with increasing energy loss in the low-loss regime, while the Bragg-diffracted beam intensities do not change significantly. The beam intensities include the diffuse scattered background and have been normalized to adjust for the inelastic scattering cross section. It is speculated that the random azimuthal scattering angle during inelastic events transfers part of the unscattered beam intensity to the inner Bragg reflections. Inelastic scattering should not significantly influence crystal structure refinement, provided there are no artefacts from any background subtraction, since the relative intensity of the diffracted beams (which includes the diffuse scattering) remains approximately constant in the low energy loss regime.

Modelling the power threshold and optimum thermal deformation of indirectly liquid-nitro­gen cryo-cooled Si monochromators

Maximizing the performance of crystal monochromators is a key aspect in the design of beamline optics for diffraction-limited synchrotron sources. Temperature and deformation of cryo-cooled crystals, illuminated by high-power beams of X-rays, can be estimated with a purely analytical model. The analysis is based on the thermal properties of cryo-cooled silicon crystals and the cooling geometry. Deformation amplitudes can be obtained, quickly and reliably. In this article the concept of threshold power conditions is introduced and defined analytically. The contribution of parameters such as liquid-nitro­gen cooling efficiency, thermal contact conductance and interface contact area of the crystal with the cooling base is evaluated. The optimal crystal illumination and the base temperature are inferred, which help minimize the optics deformation. The model has been examined using finite-element analysis studies performed for several beamlines of the Diamond-II upgrade.

Canadian Blood Services research engineer applies network modelling techniques and mentorship skills to benefit Canada’s Lifeline

Canadian Blood Services research engineer applies network modelling techniques and mentorship skills to benefit Canada’s Lifeline


Tuesday, October 22, 2024 Dr. Emily Freeman

Dr. John Blake is a research engineer at Canadian Blood Services and a Professor in the Department of Industrial Engineering at Dalhousie University. Based in Halifax, Nova Scotia, Dr. Blake and his trainees use engineering principles and various computer-based optimization techniques to inform large scale decisions at Canadian Blood Services.  

Applying network modelling to biologics  

To some, it may be surprising to learn that there is such opportunity to integrate engineering into the health-care focused setting of Canadian Blood Services. However, as Dr. Blake explains, the same engineering principles that apply to the development and quality assurance of other products also apply to biologics such as blood, stem cells and organs. One of these classic engineering approaches currently applied to improving operations at Canadian Blood Services is network modelling.  

Network modelling is a computer-based method that creates a virtual representation of objects and their relation to each other. The resulting models are particularly useful for maintaining adaptability in the collection of blood donations, as well as the distribution and inventory management strategies that allow Canadian Blood Services to remain a safe and reliable provider of life-saving products.

Contributing to efficiency and sustainability in Canada’s Lifeline  

For Dr. Blake’s team, modelling is not about the data acquired but rather how they can turn existing data into real life change. Part of this approach is ensuring that Canadian Blood Services is asking the right questions when it comes to allocating resources. For example, Dr. Blake has worked on models to assess how changing stem cell donor recruitment will affect the number of matches for Canadian patients. By modelling things such as recruitment approaches, Dr. Blake’s work assists Canadian Blood Services to consistently identify ways to improve Canada’s Lifeline.

Recently, Dr. Blake has also been applying this method to optimize the number and location of mobile and permanent donor facilities across the nation. This redesign of the donation facility network will address the growing demand for donations by bringing Canadian Blood Services’ facilities closer to the donors. 

“I have waited my entire career for a problem of this type – it is truly a once in a lifetime opportunity.”

Dr. John Blake, Canadian Blood Services Research Engineer

Securing the future of Canada’s Lifeline  

To sustain a safe and effective blood system in Canada for years to come, network modelling and optimization is a never-ending process. This is one of the reasons that Dr. Blake is committed to securing the future of transfusion and transplantation systems by training and mentoring the next generation of engineers. In fact, seeing his former students join Canadian Blood Services and dedicate their talents to improving the future of Canada’s Lifeline is one of Dr. Blake’s proudest achievements.  

One of Dr. Blake’s former students, Matt Nelson, is now an industrial engineer at Canadian Blood Services.  

“In my role, I use systematic thinking to build and run complex models; collect and analyze the required data; produce useful results; and explain these results to non-technical leaders on a regular basis,” Matt says. Recently, Matt contributed to the launch and expansion of pathogen-reduced platelets, a new product that was implemented across Canadian Blood Services production sites starting in 2022. The implementation of pathogen-reduced platelets has provided an additional layer of safety for recipients by reducing the risk of potential transfusion-transmitted pathogens without compromising the quality of the component. Matt credited Dr. Blake in helping him develop the necessary skills he now dedicates to safeguarding Canada’s Lifeline:  

“Dr. Blake was the professor who introduced me to the uses of simulation to understand complex non-linear systems. This type of system is very common in situations that have a lot of variability – like the blood system – and simulation allows for exploration of the response of the system to changes.” 

Matt Nelson, Canadian Blood Services Industrial Engineer

Over the years, Dr. Blake’s ongoing modelling work and mentorship activities have also led to many recognitions and awards, but he is most proud of being recognized as Professor of the Year by Dalhousie Undergraduate students, and with awards for his contributions to the Canadian Operational Research Society. He has even the earned the distinction of being Dalhousie’s first engineer to be awarded grant funding from the tri-council agency, Social Sciences and Humanities Research Council (SSHRC). 

“I am proud to work on projects that have a measurable impact on people’s health and well-being,” Dr. Blake says. “I am forever grateful to Dr. Dana Devine for first giving me the opportunity to serve Canadians in this role at Canadian Blood Services.”

Ridiculous value for a monitor with these specs, even with no stand and shipping costs - paid $38 for StarTrack to Brisbane area, so $237 total, ordered Sunday arrived today.

Should go without saying it's not an ideal monitor for gaming, but honestly it would be plenty enjoyable for many titles imo (just not competitive shooters etc).

The screen was well packed and works perfectly, has a great picture and there were no scratches or dead pixels on my unit.

Specs:

Size & Resolution: 34-inch, UltraWide, 3440 x 1440 (WQHD)
Aspect Ratio: 21:9
Panel Type: IPS
Colour Coverage: 99% sRGB

Weight: 8.2kg without stand

Pros:

  • good bit newer than popular U3415W from recent deals
  • decent brightness at 300 cd/m²
  • USB-C with solid power delivery at 90W
  • USB hub and KVM switch
  • excellent overall value

Cons:

  • 60Hz peasantry
  • useless "fast" overdrive mode (visible overshoot like if mouse trails were enabled, just don't)

Before anyone has a sook about the "free shipping over $199" like on that last thread, it's a pretty heavy unit at 8.2kg (not incl. packaging) and the exclusion is clearly stated on BPC's shipping policy page.

Cheers for the mad bargain BPC, couldn't be happier.
