Abstract While many of the proteins involved in the mitotic centromere and kinetochore are conserved in meiosis, they often gain a novel function due to the unique needs of homolog segregation during meiosis I (MI). CENP-C is a critical component of the centromere for kinetochore assembly in mitosis. Recent work, however, has highlighted the unique features of meiotic CENP-C. Centromere establishment and stability require CENP-C loading at the centromere for CENP-A function. Pre-meiotic loading of proteins necessary for homolog recombination as well as cohesion also rely on CENP-C, as do the main scaffolding components of the kinetochore. Much of this work relies on new technologies that enable in vivo analysis of meiosis like never before. Here, we strive to highlight the unique role of this highly conserved centromere protein that loads on to centromeres prior to M-phase onset, but continues to perform critical functions through chromosome segregation. CENP-C is not merely a structural link between the centromere and the kinetochore, but also a functional one joining the processes of early prophase homolog synapsis to late metaphase kinetochore assembly and signaling.

AbstractStability is now a critical factor in the commercialization of organic photovoltaic (OPV) devices. Both extrinsic stability to oxygen and water and intrinsic stability to light and heat in inert conditions must be achieved. Triplet states are known to be problematic in both cases, leading to singlet oxygen production or fullerene dimerization. The latter is thought to proceed from unquenched singlet excitons that have undergone intersystem crossing (ISC). Instead, we show that in bulk heterojunction (BHJ) solar cells the photo-degradation of C60 via photo-oligomerization occurs primarily via back-hole transfer (BHT) from a charge-transfer state to a C60 excited triplet state. We demonstrate this to be the principal pathway from a combination of steady-state optoelectronic measurements, time-resolved electron paramagnetic resonance, and temperature-dependent transient absorption spectroscopy on model systems. BHT is a much more serious concern than ISC because it cannot be mitigated by improved exciton quenching, obtained for example by a finer BHJ morphology. As BHT is not specific to fullerenes, our results suggest that the role of electron and hole back transfer in the degradation of BHJs should also be carefully considered when designing stable OPV devices.

The Saint with Indra's Sword: Khruubaa Srivichai and Buddhist Millenarianism in Northern Thailand

AbstractDespite a growing literature revealing the presence of millenarian movements in both Theravada and Mahayana Buddhist societies, scholars have been remarkably reluctant to consider the role of messianic beliefs in Buddhist societies. Khruubaa Srivichai (1878–1938) is the most famous monk of northern Thailand and is widely revered as atonbun, or saint. Althoughtonbunhas been depoliticized in the modern context, the term also refers to a savior who is an incarnation of the coming Maitreya Buddha. In 1920 Srivichai was sent under arrest to the capital city of Bangkok to face eight charges. This essay focuses on the charge that he claimed to possess the god Indra's sword. Although this charge has been widely ignored, it was in fact a charge of treason. In this essay, I argue that the treason charge should be understood within the context of Buddhist millenarianism. I note the saint/savior tropes in Srivichai's mytho-biography, describe the prevalence of millenarianism in the region, and detail the political economy of the decade of the 1910s prior to Srivichai's detention. I present evidence to show that the decade was characterized by famine, dislocation, disease, and other disasters of both natural and social causes. Such hardships would have been consistent with apocalyptic omens in the Buddhist repertoire portending the advent of Maitreya. Understanding Srivichai in this millenarian context helps to explain both the hopes of the populace and the fears of the state during that tumultuous decade.
