Saint Peter, King of Bulgaria (970)

"Saint Peter was a humble, devout and peace-loving man, unlike his father, Tsar Symeon the Warrior (d. 927), during whose reign there had been perpetual warfare. By contrast, Peter's long reign was peaceful, and notable for the restoration of good relations with Byzantium and with the West. Peter married Maria, the grand-daughter of the Emperor Romanus Lecapenus, who recognized him as basileus (tsar or king), and he obtained independence from Constantinople for the Bulgarian Church with its own Patriarch. He had a great love for Saint John of Rila (19 Oct.), whom he would often consult, and he kept in touch with renowned ascetics of the time like Saint Paul of Latros (15 Dec.). The King acted energetically against the Bogomil heresy, an offshoot of Manicheism, by which some of his people, lacking sufficient instruction in the faith, were being misled. He called a council in order to condemn the heresy and reassert Christian principles. Nevertheless, the infection was to remain active for many years in Bulgaria. Following the invasion of the north of his Kingdom by Prince Svyatoslav of Kiev in 969, Peter abdicated and became a monk. He died in the following year, having consecrated his final days to God alone." (Synaxarion)   A note on the Bogomils: The Bogomils flourished in the Eastern Europe as an organized church from the 10th to the 15th century. In theology they were dualistic, incorporating some Manichean and Gnostic ideas from the Paulicians. They were nationalistic and gained much support through their opposition to Byzantine dominance over the Slavic peoples. They disappeared as an organized body around the fifteenth century, but elements of their beliefs persisted in popular thinking for many centuries afterward.

Blessed Equal-to-the-Apostles Olga, princess of Russia, in holy baptism called Helen (969).

"Saint Olga, renowned for her wisdom and sobriety, in her youth became the wife of Igor, Great Prince of Kiev, who ruled during the tenth century. After her husband's death, she herself ruled capably, and was finally moved to accept the Faith of Christ. She travelled to Constantinople to receive Holy Baptism. The Emperor, seeing her outward beauty and inward greatness, asked her to marry him. She said she could not do this before she was baptized; she furthermore asked him to be her Godfather at the font, which he agreed to do. After she was baptized (receiving the name of Helen), the Emperor repeated his proposal of marriage. She answered that now he was her father, through Holy Baptism, and that not even among the heathen was it heard of a man marrying his daughter. Gracefully accepting to be outwitted by her, he sent her back to her land with priests and sacred texts and holy icons. Although her son Svyatoslav remained a pagan, she planted the seed of faith in her grandson Vladimir (see July 15). She reposed in peace in 969." (Great Horologion)

Holy Tsar Boris-Michael of Bulgaria (907)

A son of the Bulgarian Khan Presian, he was instructed in the faith by St Photios, Patriarch of Constantinople. He labored throughout his reign to establish and spread the Christian faith in Bulgaria. When the disciples of Ss Cyril and Methodius were driven from Moravia and came to Bulgaria, he greatly assisted them in their missionary work there. He retired to a monastery, leaving rule of his country in the hands of his son Vladimir. But when he learned that Vladimir was persecuting Christians and trying to re-establish paganism, he left the monastery, took up the sword, overthrew his son, put his younger son Symeon on the throne and, when he was confident that the country was again in Christian hands, returned to the monastery, where he ended his life in peace and piety.

Adam DeVille on Self-Care as Asceticism (not self-indulgence)

Join Fr. Anthony in Hartwell, GA as he talks with Professor Adam DeVille (University of Saint Francis, Fort Wayne, IN) about proper and improper ways of framing self-care, why it is so easy to get it wrong, and why it is important to get it right. They also spend quite a bit of time talking about reconciliation and polarization. Dr. DeVille is the author of Everything Hidden Shall Be Revealed: Ridding the Church of Abuses of Sex and Power. He blogs (prolifically and well) at “Eastern Christian Books.” There’s a bit of ironically timed electronic mischief in the middle, but the worst of it has been edited out. This is the audio from Fr. Anthony’s YouTube livestream (12/21/2020). Professor DeVille’s article on this topic is available here.

The Morning After: LG’s new twisty display tech can stretch up to 50 percent

LG Display’s new free-form screen technology can expand from 12 to 18 inches, with a resolution of 100ppi. The display also uses a micro-LED light source smaller than 40 micrometers, so it can apparently be stretched over 10,000 times. While this probably isn’t your next smartphone, we could see the tech in clothing, car panels and more.

LG Display has pushed the boundaries of screen tech for a while, revealing folding screens before foldable phones appeared, roll-up TVS before roll-up TVs went on sale and transparent displays before they appeared in fancy stores, theme parks and elsewhere. So expect to see this Bop-it of displays somewhere, eventually.

Fujifilm

Fujifilm is developing a medium-format, 102-megapixel cinema camera, the company said in a surprise announcement. Due next year, the GFX Eterna will carry a boxy, modular design reminiscent of Sony’s FX6. The new camera will have a medium format GFX 102-megapixel (MP) CMOS II HS sensor, the same one used on the GFX100 II. That sensor is 43.8mm x 32.9 mm in size — that’s 1.7 times larger than the full-frame sensor on the FX.

The benefits will be extra dynamic range, potentially high resolution and a very shallow depth of field, which should enable cinematic shots with the right lens. Having said that, Fujifilm currently has no GFX glass designed specifically for film production. It’s working on it, though.

A New Approach to Water Flow Algorithm for Text Line Segmentation

This paper proposes a new approach to water flow algorithm for the text line segmentation. Original method assumes hypothetical water flows under a few specified angles to the document image frame from left to right and vice versa. As a result, unwetted image frames are extracted. These areas are of major importance for text line segmentation. Method modifications mean extension values of water flow angle and unwetted image frames function enlargement. Results are encouraging due to text line segmentation improvement which is the most challenging process stage in document image processing.

Nondeterministic Query Algorithms

Query algorithms are used to compute Boolean functions. The definition of the function is known, but input is hidden in a black box. The aim is to compute the function value using as few queries to the black box as possible. As in other computational models, different kinds of query algorithms are possible: deterministic, probabilistic, as well as nondeterministic. In this paper, we present a new alternative definition of nondeterministic query algorithms and study algorithm complexity in this model. We demonstrate the power of our model with an example of computing the Fano plane Boolean function. We show that for this function the difference between deterministic and nondeterministic query complexity is 7N versus O(3N).

Least Slack Time Rate first: an Efficient Scheduling Algorithm for Pervasive Computing Environment

Real-time systems like pervasive computing have to complete executing a task within the predetermined time while ensuring that the execution results are logically correct. Such systems require intelligent scheduling methods that can adequately promptly distribute the given tasks to a processor(s). In this paper, we propose LSTR (Least Slack Time Rate first), a new and simple scheduling algorithm, for a multi-processor environment, and demonstrate its efficient performance through various tests.

Algorithms for the Evaluation of Ontologies for Extended Error Taxonomy and their Application on Large Ontologies

Ontology evaluation is an integral and important part of the ontology development process. Errors in ontologies could be catastrophic for the information system based on those ontologies. As per our experiments, the existing ontology evaluation systems were unable to detect many errors (like, circulatory error in class and property hierarchy, common class and property in disjoint decomposition, redundancy of sub class and sub property, redundancy of disjoint relation and disjoint knowledge omission) as defined in the error taxonomy. We have formulated efficient algorithms for the evaluation of these and other errors as per the extended error taxonomy. These algorithms are implemented (named as OntEval) and the implementations are used to evaluate well-known ontologies including Gene Ontology (GO), WordNet Ontology and OntoSem. The ontologies are indexed using a variant of already proposed scheme Ontrel. A number of errors and warnings in these ontologies have been discovered using the OntEval. We have also reported the performance of our implementation, OntEval.

Multi-agent Q-learning algorithm-based relay and jammer selection for physical layer security improvement

Physical Layer Security (PLS) and relay technology have emerged as viable methods for enhancing the security of wireless networks. Relay technology adoption enhances the extent of coverage and enhances dependability. Moreover, it can improve the PLS. Choosing relay and jammer nodes from the group of intermediate nodes effectively mitigates the presence of powerful eavesdroppers. Current methods for Joint Relay and Jammer Selection (JRJS) address the optimisation problem of achieving near-optimal secrecy. However, most of these techniques are not scalable for large networks due to their computational cost. Secrecy will decrease if eavesdroppers are aware of the relay and jammer intermediary nodes because beamforming can be used to counter the jammer. Consequently, this study introduces a multi-agent Q-learning-based PLS-enhanced secured joint relay and jammer in dual-hop wireless cooperative networks, considering the existence of several eavesdroppers. The performance of the suggested algorithm is evaluated in comparison to the current algorithms for secure node selection. The simulation results verified the superiority of the proposed algorithm.
