Machine Learning for Prediction and Causal Inference
Authors: Weeks Melvyn 
Published: December 2023

This seminar explores machine learning techniques for prediction and causal inference, where a researcher or decision maker needs to make a prediction or understand the impact of an intervention in a heterogenous population. For example, researchers may want to infer the effect of an economic, educational, or public health intervention, or a firm may seek to understand how a change in pricing will impact aggregate demand. In these cases, the interest may be in an average effect, but also how the effect varies over different segments of the population (i.e., heterogeneity in the effect). This seminar will provide you with the tools to undertake such inquiry using machine learning (ML), while ensuring that you understand and can communicate how the methods work for prediction and causal inference. An official Instats certificate of completion is provided at the conclusion of the seminar. For European PhD students, the seminar offers 2 ECTS Equivalent points.

Published: December 2023

AbstractCharacterization of multilayer coatings in 3D presents many challenges, as composition can change by area and by depth. Compositional characteristics of the interior of multilayer coatings emerge during analysis, so are frequently discovered only through exacting retrospective investigations. Time‐of‐flight secondary ion mass spectrometry (ToF‐SIMS) can be used to elucidate such complex systems; however, data analysis is a challenge. In this work a detail presentation is done of 3D chemical characterization of a low emissivity (low‐E) double silver coating on glass using ToF‐SIMS and machine learning. An unsupervised machine learning technique, the self‐organizing map with relational perspective mapping, is used to visualize the chemical similarity between different layers of the low‐E film. Repeating layers are easily identified at the single‐voxel level, based on their entire mass spectra, and are classified as chemically indistinguishable. All major film components are identified, including the use of SnO2 as a dielectric, ZnO seeding layers, TiOx blocking layers, a Zn base layer, and a TiOx topcoat. The thin optically active silver layers are examined in detail, demonstrating subtle chemical changes with depth. This technique provides excellent insight into manufacturing processes and production challenges and has excellent potential in forensic applications.

Published: December 2023

AbstractAs the prevalence of electromagnetic interference (EMI) continues to rise, there is a growing demand for shielding materials, which play a crucial role in electronic devices, communication systems, health protection, etc. However, conventional EMI shielding materials encounter difficulties in effectively addressing the escalating intricacies of electromagnetic environments and diverse shielding scenarios, wherein foldability, flexibility, and lightweight are desired. In this work, a novel EMI shielding material, silver‐hollow‐fiber (AgHF), is developed by combining blow‐spinning, UV radiation, and temperature‐controlled annealing technologies. During the fabrication process, UV radiation is used to selectively reduce silver ions on the outer surface of precursor fiber, and temperature‐controlled annealing is further employed to remove the inside polymer, forming a hollow fiber structure. The AgHF exhibits superior flexibility, lightweight, remarkable mechanical stability, and excellent EMI shielding efficiency (SE). Particular, the AgHF with a thickness of 163 µm demonstrates an EMI SE of 101.65 dB, and with minimal degradation of less than 10% even after undergoing 2000 bending cycles. The remarkable EMI shielding performance, combined with the lightweight, flexibility, and mechanical stability of AgHF, positions it as a highly promising material for a wide range of EMI shielding applications in the future.

AbstractThe advent of multi‐resonance thermally activated delayed fluorescence (MR‐TADF) materials, heralding cutting‐edge emitters with superior efficiency and color fidelity, represents a momentous stride in the realm of organic light‐emitting diodes (OLEDs). In this particular investigation, substantial advancements have been made by enhancing, synthesizing, and characterizing three distinct MR‐type emitters through meticulous control of peripheral decorations using frontier molecular orbital engineering. Through strategic attachment of various pyrimidine derivatives to the positions of the lowest unoccupied molecular orbitals (LUMO) of the parent molecule, the molecular excited state attributes are meticulously tailored, leading to the development of orange‐red MR‐TADF emitters. These designed molecules have demonstrated an emission spectrum shift from orange‐red to orange, exhibiting peak wavelengths spanning the range of 585–608 nm and full width at half‐maximums (FWHM) between 36 and 43 nm. This signifies a remarkable precision in managing the emission maxima of MR‐TADF emitters. Astonishingly, the solution‐processed OLEDs have showcased vibrant orange‐red electroluminescence, characterized by peak wavelengths ranging from 587 to 611 nm, accompanied by a notable external quantum efficiency nearing 20%.

Published: December 2023

AbstractArticular cartilage injuries and osteochondral defects are a significant clinical challenge, as conventional treatments often have limited success. Articular cartilage has limited self‐regeneration ability due to the absence of blood vessels, nerves, and lymphatic vessels, making it challenging to repair tissue defects and restore motor function in injured or aging populations. Additionally, the anatomical complexity and slow regeneration capacity of hyaline cartilage at the osteochondral interface pose significant problems in repairing osteochondral defects. Melt electrowriting, a novel technology particularly suitable for polycaprolactone (PCL) is expected to overcome the common limitations of 3D‐printed scaffolds, such as poor tissue‐porosity matching, low resolution, and inflexible shapes. In recent years, melt electrowriting (MEW) has become a promising strategy for repairing cartilage and osteochondral defects. However, there is still a lack of systematic understanding regarding the comparative characteristics and application value of MEW compared with commonly used 3D printing technologies such as extrusion printing, inkjet printing, and fusion deposition modeling. This review paper compares the characteristics and advantages of MEW and common 3D printing technologies, providing a comprehensive summary of the significant progress and applications of MEW for cartilage/osteochondral repair. Finally, the challenges and key directions for future research in MEW technology will also be discussed.

Published: December 2023

AbstractHand gesture plays an important role in many circumstances, which is one of the most common interactive methods in daily life, especially for disabled people. Human–machine interaction is another popular research topic to realize direct and efficient control, making machines intelligent and maneuverable. Here, a special human–machine interaction system is proposed and namedas computer‐vision (CV) based gesture‐metasurface interaction (GMI) system, which can be used for both direct beam manipulations and real‐time wireless communications. The GMI system first needs to select its working mode according to the gesture command to determine whether to perform beam manipulations or wireless communications, and then validate the permission for further operation by recognizing unlocking gesture to ensure security. Both beam manipulation and wireless communication functions are validated experimentally, which show that the GMI system can not only realize real‐time switching and remote control of different beams through gesture command, but also communicate with a remote computer in real time by translating the gesture language to text message. The proposed non‐contact GMI system has the advantages of good interactivity, high flexibility, and multiple functions, which can find potential applications in community security, gesture‐command smart home, barrier‐free communications, and so on.

Published: December 2023

AbstractA 24%‐efficient single‐junction GaAs solar cell grown directly on a faceted, spalled (100) GaAs substrate after in situ planarization growth by hydride vapor phase epitaxy (HVPE) is achieved. Controlled spalling, a promising low‐cost substrate reuse technique, produces large facets in (100)‐oriented GaAs substrates due to the orientation of the fracture planes used for lift‐off. Planarization by HVPE offers a path toward direct use of these spalled substrates without costly polishing steps. Here, the growth rate anisotropy enabling planarization arising from diffusion and differences in the adsorption of growth species on {n11}B‐type facets relative to (100) is determined. Consecutive planarization and device growth that results in a solar cell with a minimal performance difference relative to a control cell grown on an epitaxy‐ready substrate are demonstrated. These results show that controlled spalling coupled with HVPE planarization is a viable pathway for lowering the cost of III‐V photovoltaics.

AbstractRecently, due to its flexibility and ease of integration into wearable electronics, interest in fiber‐shaped batteries (FSBs) is burgeoning. While there is much research focused on improving the electrochemical performance of FSBs, little work is done to evaluate the safety and comfort of integrated FSBs for wearable electronics, which will significantly hinder the further development of high‐performance FSBs and their commercialization. In this review, the design, integration, and evaluation of FSBs incorporated in common textiles are fully discussed. Traditional textile characterization techniques and modern methods to evaluate its durability are also summarized. Finally, in view of developing commercial wearable battery textiles, a perspective toward improving the design of high‐performance FSB is presented.

Published: December 2023

AbstractDescribed herein presents a kind of multisite hybrid ionic liquid‐catalysts and establishes a novel strategy for H2S utilization, which has been characterized by multiaspects to reveal internal structural characterization. Through chemical modification, the D101‐based hybrid ILs were used for the direct synthesis of thioamides from the addition of H2S and nitriles. D101‐[PMDETA][DMG] can achieve an impressive activity of quantitative conversion for benzonitrile. Reaction kinetics, adsorption thermodynamics, substrate universality, and catalyst cycling experiments have been systematically studied. A first‐order kinetic model was constructed and studied experimentally for the reaction of nitriles with H2S to produce thioamides. The internal mechanism was proposed through experiments and confirmed by DFT‐based theoretical calculations. Moreover, D101‐based hybrid ILs can be easily recovered, thus completing the cyclic process of thioamide multiplication. This work not only offers an effective method for the construction of organic‐inorganic hybrid materials but also provides a novel insight into efficient H2S conversion.

Published: December 2023

AbstractThe treatment of purified terephthalic acid wastewaters via anaerobic methods poses a significant challenge due to the slow degradation rate and extended reaction time required for the most recalcitrant terephthalic acid (TA). To address this challenge, this study investigated the efficacy of various semiconductors in promoting TA degradation and determined their respective functional roles. Results showed that the addition of g‐C3N4 increased methane production by 28.38%, indicating its potential as a replacement for TiO2 in TA degradation. The improvement was attributed to the intensified direct interspecies electron transfer (DIET) process, facilitated by microorganisms that directly utilize conductive TiO2/g‐C3N4 as intermediaries to accelerate the electron transfer rate. The unfavorable methanogenesis performances of CeO2 and Fe2O3 were accredited to agglomeration phenomena and toxic effects. This study provides insights into the roles of exogenous materials in promoting or limiting the DIET process, and offers an environmentally friendly and highly‐effective strategy for treating industrial purified‐terephthalic acid wastewater.
