    Author's details edited by Jun Zhang, Michael V. Knopp
    Abstract This book is a guide to new and emerging PET technology, instrumentation, and its place in clinical practice. PET technology is currently moving from the conventional photomultiplier tube (PMT) detector based PET to the new generation, solid state light sensor detector. This is a technological leap and holds significant implications for the use of PET imaging. This book introduces and describes the emerging and new generation of PET instrumentations and technologies across manufactures, focusing on solid-state PET detector designs, system characteristics, and clinical practices as well as future advanced Time-of-Flight (TOF) PET technologies. Organized into three sections, the basics of PET imaging; solid state digital PET instrumentation, technology, and clinical practice; and a look to the future of PET imaging, chapters present a full picture of PET imaging, where we are and where we will be. Nuclear medicine physicians, physicists, and technologists can use this book to better understand future PET systems, novel PET technologies, and potential game changes of clinical PET practice.

    Abstract What are the relationships among environmental regulations, green finance, and environmental damages in countries? Existing literature supports the impact of green finance or green innovation on environmental quality, but rare studies query the cointegration among other core variables. We thus utilize the yearly data of 25 Chinese provinces from 2003 to 2021 to empirically examine the relationships among access to clean energy and technology, environmental regulation, renewable green investment, subsidy on green energy, and green finance index in environmental damage compensation via an augmented mean group (AMG) and other estimators. However, the current empirical research also investigates the individual linkage of green finance components with explained variables. Overall, this study confirms the existence of cointegration relationships among these variables. Moreover, the results of AMG suggest that access to clean fuels and technology, environmental regulations, and green finance can inversely affect the explained variable in the long term. Furthermore, environmental regulations and renewable green investment positively affect environmental damages, while a separate proxy of green finance also negatively affects explained variables in the selected provinces with better environmental performance. Our empirical findings offer important policy implications for overall emerging economies to promote subsidies, environmental regulations, and green finance to improve environmental damages compensation.

    Abstract This study develops a model based on a general equilibrium framework to assess the excess burden of carbon taxes imposed on energy commodities (electricity and natural gas) among residential sector. The model takes into account labor market distortions from the tax and cross-price effects among energy commodities. Using data from the U.S. Residential Energy Consumption Survey, the own-price and cross-price elasticities of energy commodities are estimated. A substitution effect is found between electricity and natural gas, and omitting this effect would overestimate the excess burden of the carbon tax. The results show that the carbon tax behaves differently in affecting the excess burden for low-, middle-, and high-income households. The excess burden is lower for high-income households than for low-income households at lower pre-determined labor tax rates, but the effect is reversed at higher pre-determined labor tax rates. In addition, the empirical results show that the excess burden is different across the nine U.S. regions, while minor gas price changes have no significant effect on the excess burden.

    Abstract Writing and reading are closely related and are thus likely to have a common orthographic representation. A fundamental question in the literature on the production of written Chinese characters concerns the structure of orthographic representations. We report on a Chinese character handwriting pedagogical corpus involving a class of 22 persons, 232 composite character types, 1,913 tokens, and 13,057 stroke records, together with the inter-stroke interval (ISI), which reflects the parallel processing of multilevel orthographic representation during the writing execution, and 50 orthographic variables from the whole character, logographeme, and stroke. The results of regression analyses show that orthographic representation has a hierarchy and that different representational levels are active simultaneously. In the multilevel structure of orthographic representation, the representation of the logographeme is absolutely dominant. Writing and reading have both commonalities and individual differences in their orthographic representations. The online processing of the logographeme unit probably occurs at the ISI before the initial stroke of the current logographeme, which may also cascade to the first subsequent logographeme. In addition, we propose a new effective character structure unit for describing orthographic complexity.

    Abstract Atom typing is the first step for simulating molecules using a force field. Automatic atom typing for an arbitrary molecule is often realized by rule-based algorithms, which have to manually encode rules for all types defined in this force field. These are time-consuming and force field-specific. In this study, a method that is independent of a specific force field based on graph representation learning is established for automatic atom typing. The topology adaptive graph convolution network (TAGCN) is found to be an optimal model. The model does not need manual enumeration of rules but can learn the rules just through training using typed molecules prepared during the development of a force field. The test on the CHARMM general force field gives a typing correctness of 91%. A systematic error of typing by TAGCN is its inability of distinguishing types in rings or acyclic chains. It originates from the fundamental structure of graph neural networks and can be fixed in a trivial way. More importantly, analysis of the rationalization processes of these models using layer-wise relation propagation reveals how TAGCN encodes rules learned during training. Our model is found to be able to type using the local chemical environments, in a way highly in accordance with chemists' intuition.

    Abstract Endothelial activation and dysfunction is an important contributor to atherosclerosis, cardiovascular diseases and cardiorenal syndrome. Endothelial dysfunction is also linked with metabolic syndrome and type II diabetes. The search for specific and sensitive biomarkers of endothelial activation and dysfunction may have important clinical implications. This review pinpoints the differences in biomarkers between endothelial activation and endothelial dysfunction in cardiovascular diseases, and then briefly describes the most relevant biomarkers of endothelial activation. Biomarkers of endothelial activation include endothelial adhesion molecules, cytokines, C-reactive protein, CD62E+/E-selectin activated endothelial microparticles, oxidation of low density lipoproteins, asymmetric dimethylarginine and endocan. This review also presents an update on the novel biomarkers of endothelial dysfunction, such as matrix metalloproteinases (e.g., MMP-7, MMP-9), ANGPTL2, endogdlin, annexin V+ endothelial apoptotic microparticles, and serum homocysteine. Finally, this review emphasizes the limitations of biomarkers of endothelial activation and dysfunction in clinical setting.

    Abstract Background: Telomere maintenance is increasingly being considered as fundamental to the progression of immune-mediated inflammatory diseases. However, the causality underlying the purported relationship has not been fully elucidated. In the present work, we applied Mendelian randomization (MR) analysis to obtain estimates of the causal effect of telomere length (TL) on the risk of juvenile idiopathic arthritis (JIA) and JIA-associated iridocyclitis.
    Methods: Two-sample MR analysis was conducted using summary-level data from the largest genome-wide association studies concerning TL (78,592 individuals), JIA (6056 cases and 25,086 controls), and JIA-associated iridocyclitis (1430 cases and 9,2767 controls). All the participants were of European ancestry. The inverse variance weighted (IVW) method was applied to estimate the causal effects. Sensitivity analyses incorporating multiple complementary MR approaches were implemented to test the robustness of the association and examine potential bias from pleiotropy.
    Results: In our MR analysis, genetically predicted shorter TL was associated with an increased risk of JIA (IVW: odds ratio=1.68, 95% CI: 1.13-2.48,
    Conclusion: This work provides evidence of a negative association between TL and JIA risk, but not for the association between TL and the risk of JIA-associated iridocyclitis, in a European population. Future studies with larger sample sizes are warranted to elucidate the underlying role of TL in these diseases.

    Abstract Power side-channel attacks, have become a serious threat to embedded computing devices in cyber-physical systems because of the ability of deducing secret data using statistical analysis. A common strategy for designing countermeasures against power-analysis-based side-channel attacks uses random masking techniques to remove the statistical dependency between secret data and side-channel information. Although existing techniques can verify whether a piece of cryptographic software code is perfectly masked, they are limited in accuracy and scalability. In order to eliminate such limitations, a refinement-based method for verifying masking countermeasures is proposed. This method is more accurate than prior type-inference based approaches and more scalable than prior model-counting based approaches using satisfiability (SAT) or satisfiability modulo theories (SMT) solvers. Indeed, this method uses a set of semantic type-inference rules to reason about distribution type. These rules are kept abstract initially to allow fast deduction, and then specified when the abstract version is not able to resolve the verification problem. This method is implemented in a software tool called SCVerify and is evaluated on cryptographic benchmarks including advanced encryption standard (AES) and message authentication code Keccak (MAC-Keccak). The experimental results show that the method significantly outperforms state-of-the-art techniques in terms of accuracy and scalability.
