noc St Innocent, enlightener of Alaska and Siberia (1879) By www.ancientfaith.com Published On :: 2020-01-21T21:42:30+00:00 He was born in Siberia in 1797 to a clerical family, and became a married parish priest in Irkutsk. A devout explorer, John Kriukov, told him of the great spiritual needs among the Russian and native peoples in Alaska, then Russian territory. Moved to serve Christ in this very difficult environment, he and his family arrived in Alaska in 1824. He quickly learned the Aleut language and worked humbly and tirelessly among the Aleuts. His spiritual classic, An Indication of the Way to the Kingdom of Heaven, was originally written in Aleut and later translated into many languages. While he was visiting Russia in 1838, his wife died; one year later he was tonsured a monk and given the name of Innocent (he had been Fr John Veniamov). Almost immediately after his tonsuring he was, without warning, raised to the rank of Bishop of all Eastern Siberia and Russian America, probably the largest diocese in the world at that time. Returning to Alaska, he continued his missionary work with vigor, often traveling among Aleut and Tlingit settlements in his own kayak. Wherever he went, he found the Alaskan people hungry for the faith, and his labors bore rich fruit which is still obvious today: Alaska has more Orthodox churches per capita than any other state. In old age he was made Metropolitan of Moscow, head of the entire Russian Orthodox Church. His concern for Christian mission was undiminished, and as Metropolitan he created the Orthodox Missionary Society. He reposed on Holy Saturday of 1879. Full Article
noc Our Holy Father Innocent, Bishop of Irkutsk (1731) By www.ancientfaith.com Published On :: 2020-01-22T04:34:16+00:00 He was descended from a noble family near Chernigov. He became a monk at the Lavra of the Kiev Caves in 1706 and in 1721 was consecrated bishop. He was sent as a missionary to China but, due to political complications, could not gain entry into the country and settled temporarily near Lake Baikal in Siberia. He and his companions soon ran out of money and were forced to live for a time on alms and by day- labor. Rather than become discouraged, Saint Innocent made use of this time to learn the native language and found a school for the local Mongol people, many of whom he brought to the faith. In 1722 he was appointed Bishop of Irkutsk, a diocese that covered all the huge area of eastern Siberia. At the time of his appointment there were only about thirty churches in the whole diocese. For ten years the bishop devoted himself to converting the Mongol peoples, preaching to them and catechizing them in their own language. At the same time he worked for moral reform among the Russian Orthodox people of the region. As bishop, he lived in the Monastery of the Ascension in Irkutsk, where he established a firm ascetical life, in which he himself took a full part. He spent every night in prayer, meditation on the writings of the Fathers, and preparing sermons in both Russian and the local languages. Under the strain of the cruel Siberian climate the Saint fell ill and reposed in 1731. Many miracles take place to this day at his tomb. Among the people of Siberia he is honored as highly as Saint Nicholas and counted as the Enlightener of their land. Full Article

This is a classic example of the self-destructiveness of power politics in the long term, when power is unchecked in wreaking havoc on others for short-term "feel good" gains, under the temptation of unrealistic goals (wishful thinking). 1. Introduction: Israel, the United States, and Western Power Politics There are 3 important factors contributing to the unconditional support of Israel by the United States in recent decades.

noc Permissible domain walls in monoclinic ferroelectrics. Part II. The case of MC phases By journals.iucr.org Published On :: 2024-04-29 Monoclinic ferroelectric phases are prevalent in various functional materials, most notably mixed-ion perovskite oxides. These phases can manifest as regularly ordered long-range crystallographic structures or as macroscopic averages of the self-assembled tetragonal/rhombohedral nanodomains. The structural and physical properties of monoclinic ferroelectric phases play a pivotal role when exploring the interplay between ferroelectricity, ferroelasticity, giant piezoelectricity and multiferroicity in crystals, ceramics and epitaxial thin films. However, the complex nature of this subject presents challenges, particularly in deciphering the microstructures of monoclinic domains. In Paper I [Biran & Gorfman (2024). Acta Cryst. A80, 112–128] the geometrical principles governing the connection of domain microstructures formed by pairing MAB type monoclinic domains were elucidated. Specifically, a catalog was established of `permissible domain walls', where `permissible', as originally introduced by Fousek & Janovec [J. Appl. Phys. (1969), 40, 135–142], denotes a mismatch-free connection between two monoclinic domains along the corresponding domain wall. The present article continues the prior work by elaborating on the formalisms of permissible domain walls to describe domain microstructures formed by pairing the MC type monoclinic domains. Similarly to Paper I, 84 permissible domain walls are presented for MC type domains. Each permissible domain wall is characterized by Miller indices, the transformation matrix between the crystallographic basis vectors of the domains and, crucially, the expected separation of Bragg peaks diffracted from the matched pair of domains. All these parameters are provided in an analytical form for easy and intuitive interpretation of the results. Additionally, 2D illustrations are provided for selected instances of permissible domain walls. The findings can prove valuable for various domain-related calculations, investigations involving X-ray diffraction for domain analysis and the description of domain-related physical properties.

noc Deep learning to overcome Zernike phase-contrast nanoCT artifacts for automated micro-nano porosity segmentation in bone By journals.iucr.org Published On :: 2024-01-01 Bone material contains a hierarchical network of micro- and nano-cavities and channels, known as the lacuna-canalicular network (LCN), that is thought to play an important role in mechanobiology and turnover. The LCN comprises micrometer-sized lacunae, voids that house osteocytes, and submicrometer-sized canaliculi that connect bone cells. Characterization of this network in three dimensions is crucial for many bone studies. To quantify X-ray Zernike phase-contrast nanotomography data, deep learning is used to isolate and assess porosity in artifact-laden tomographies of zebrafish bones. A technical solution is proposed to overcome the halo and shade-off domains in order to reliably obtain the distribution and morphology of the LCN in the tomographic data. Convolutional neural network (CNN) models are utilized with increasing numbers of images, repeatedly validated by `error loss' and `accuracy' metrics. U-Net and Sensor3D CNN models were trained on data obtained from two different synchrotron Zernike phase-contrast transmission X-ray microscopes, the ANATOMIX beamline at SOLEIL (Paris, France) and the P05 beamline at PETRA III (Hamburg, Germany). The Sensor3D CNN model with a smaller batch size of 32 and a training data size of 70 images showed the best performance (accuracy 0.983 and error loss 0.032). The analysis procedures, validated by comparison with human-identified ground-truth images, correctly identified the voids within the bone matrix. This proposed approach may have further application to classify structures in volumetric images that contain non-linear artifacts that degrade image quality and hinder feature identification.
