Abstract:
The concept of blockchain, widely known as virtual currencies, saw a massive surge in popularity in recent times. As far as the security of the blockchain is concerned, consensus algorithms play a vital role in the blockchain. Research has been done separately, or comparisons between a few of them have been presented previously. In this paper, we have discussed widely used consensus algorithms in the blockchain. The consensus protocols covered in this paper include PoW (Proof of Work), PoS (Proof of Stake), DPoS (Delegated Proof of Stake), PoET (Proof of Elapsed Time), PBFT (Practical Byzantin

Abstract:
The rapid evolution of blockchain technology has led to the development of various consensus algorithms (Ben-Sasson et al., 2014), each with distinct characteristics that influence the scalability, decentralization, energy efficiency, and transaction costs within decentralized public environments (Ampel et al., 2019). This study provides a comprehensive review of prominent consensus mechanisms (Block & Marcussen, 2019), including Proof of Work (PoW), Proof of Stake (PoS), Proof of Elapsed Time (PoET), and others, to elucidate their operational principles (Hu et al., 2021), strengths, and l

AbstractWe give a simpler and refined proof of some blow-up results of smooth solutions to the Cauchy problem for the Navier–Stokes equations of compressible, viscous and heat-conducting fluids in arbitrary space dimensions. Our main results reveal that smooth solutions with compactly supported initial density will blow up in finite time, and that if the initial density decays at infinity in space, then there is no global solution for which the velocity decays as the reciprocal of the elapsed time.

Abstract:
Block-chain is widely praised as an astounding advancement because of its recent development in security. Many believe that information stored in a block-chain is secure because of its decentralization and cryptographic methods. Consensus is the most important layer in block-chain architecture, and it is responsible for the network’s security and reliability. Block-chain schemes’ stabilization relies heavily on consensus-algorithms. The article provides an in-depth explanation of the most common consensus algorithms, including Proof-of-Work (PoW), Proof-of-Stake (PoS), Proof-of-Burn (PoB), Proof-of-Activity (PoA), Proof-of-Vote (PoV) and Proof-of-Elapsed-Time (PoET). An in-depth evaluation of these consensus mechanisms has been conducted, and the results have been presented. These algorithms can be measured using a variety of metrics, including security, efficiency, and scalability. A secured system that functions properly needs to identify the algorithm and its strength. According to various parameters, such as decentralization, POA has a lower level of decentralization than other protocols.

Full text
Abstract:
Multimorbidity is increasingly prevalent as the population ages and individuals with multiple long-term conditions (MLTCs) live longer. Often each condition is treated by a separate clinician, which can lead to harmful drug-drug and drug-disease interactions. Artificial Intelligence (AI) can help to identify those at risk of poor outcomes, which is particularly difficult when managing frail patients with MLTCs. We aim to analyze MLTC trajectories, but there is limited work on clustering using Electronic Health Records (EHR) and they largely ignore the time elapsed between clinical events. In this work we adapted three machine learning methods (Word2Vec, Autoencoder, TG-CNN) to allow us to cluster the entire trajectory. The proposed methods are tested on the ACT-MOOC dataset as a proof of concept, using timelines of interaction with an online course instead of an EHR. We find that clustering using the novel TG-CNN approach, which accounts for the time between events, shows a clear separation among different clusters and is better able to represent patient/user trajectories. In future work, we will apply this methodology within CPRD as part of the NIHR-funded DynAIRx project.

Abstract:
Abstract Mary sinclair was in many ways an unlikely candidate for the role of philosopher-poet. In 1886 she was living in obscurity in North Wales with her mother and Reginald, the last brother still at home, and few people knew that she was the author of Nakiketas and Other Poems, published in that year under the pseudonym ‘Julian Sinclair’. In later years Sinclair would he acclaimed as one of the few brilliant women philosophers of her time-one of the only philosophers in England to defend idealist thought against the onslaught of mathematical philosophy and logic.1 But in the late I88os that kind of recognition was far in the future. Sinclair was still not sure of her own view of the world: the intellectual and emotional perplexity that had shaped Nakiketas continued to trouble her as she searched in vain for rational proof of God’s existence.

Abstract:
The objective evidence for the deception at Piltdown was overwhelming. The frauds extended to every aspect of the discovery—geological, archaeological, anatomical, and chemical—so that proof could be adduced three or four times over. Moreover, every time a new line of investigation was applied, it confirmed, as we have seen, what all previous evidence had established. The two Piltdown ‘men’ were forgeries, the tools were falsifications, the animal remains had been planted. The skill of the deception should not be underestimated, and it is not at all difficult to understand why forty years should have elapsed before the exposure; for it needed all the new discoveries of palaeontology to arouse suspicion, and completely new chemical and X-ray techniques to prove the suspicion justified. Professor Le Gros Clark, Dr. Oakley, and I wrote in our report that ‘Those who took part in the excavation at Piltdown had been the victims of an elaborate and inexplicable deception’. Inexplicable, indeed, for the principals were known to us as men of acknowledged distinction and highly experienced in palaeontological investigation. Woodward, in 1912, was a man of established reputation. Dawson enjoyed a solid esteem. Teilhard de Chardin was, of course, only at the beginning of his palaeontological career. Knowing their place in the world of science, we felt sure that these investigators, whose integrity there was not the slightest reason to question, had been victims—like the scientific world at large—of the deception. Arthur Smith Woodward (who was of an age with Dawson) at the time of the discovery had been Keeper of the Department of Geology at the British Museum since 1901, the year of his election to the Royal Society, and had scores of papers of very great merit to his credit. His work on fossil reptiles and fishes was on a monumental scale, and he had also made discoveries in mammalian palaeontology. He was without doubt the leading authority in his own field. His position was abundantly recognized by many awards and by appointment to many high offices—for example, Secretary, and in the Piltdown years successively Vice-President and President, of the Geological Society.

Full text
Abstract:
Racial immutability of Jews and blacks was proved through the unchanging features of the Jewish and negro face over thousands of years. From the time of Johann Kaspar Lavater, the Swiss Protestant poet and pastor from Zurich, it became almost axiomatic that there was something unique about the Jewish and negro face and head. Some argued that there was something goat-like about the Jewish face and something ape-like about the negro face. Jewish and negro eyes were considered special. Robert Knox discussed the racial face with respect to negroes and Jews, finding commonalities. For Frederic William Farrar, too, it was the overlapping categories of blacks and Jews that provided the best proof of the immutability of racial types. The indelibility of African blackness and the indelibility of Jewishness were common themes that linked Jews and negroes from medieval times to the twentieth century. Alfred Russell Wallace made the critical linkage between Jews and blacks that had underlined much racial speculation for the previous five hundred years and that would continue long after his death, particularly with respect to their unchanging, ancient pedigree and appearance. While many scholars opined that the Egyptian monuments offered the best proofs of the immutability of the Jewish and negro face, Alfred Cort Haddon considered that the Assyrian depictions of Jews were the most reliable as far as Jewish faces were concerned. Jewish faces were even to be found in west Africa.

Abstract:
On 18 December 1912 Arthur Smith Woodward and Charles Dawson announced to a great and expectant scientific audience the epoch-making discovery of a remote ancestral form of man—The Dawn Man of Piltdown. The news had been made public by the Manchester Guardian about three weeks before, and the lecture room of the Geological Society at Burlington House was crowded as it has never been before or since. There was great excitement and enthusiasm which is still remembered by those who were there; for, in Piltdown man, here in England, was at last tangible, well-nigh incontrovertible proof of Man’s ape-like ancestry; here was evidence, in a form long predicted, of a creature which could be regarded as a veritable confirmation of evolutionary theory. Twenty years had elapsed since Dubois had found the fragmentary remains of the Java ape-man, but by now in 1912 its exact evolutionary significance had come to be invested with some uncertainty and the recent attempt to find more material by the expensive and elaborate expedition under Mme. Selenka had proved entirely unsuccessful. Piltdown man provided a far more complete and certain story. The man from Java, whose geological age was unclear, was represented by a skull cap, two teeth, and a disputed femur. Anatomically there was a good deal of the Piltdown skull and, though the face was missing, there was most of one side of the lower jaw. The stratigraphical evidence was quite sufficient to attest the antiquity of the remains; and to support this antiquity there were the animals which had lived in the remote time of Piltdown man; there was even evidence of the tool-making abilities of Piltdown man. In every way Piltdown man provided a fuller picture of the stage of ancestry which man had reached perhaps some 500,000 years ago. Dawson began by explaining how it came about that he had lighted on the existence of the extremely ancient gravels of the Sussex Ouse: . . . ‘I was walking along a farm-road close to Piltdown Common, Fletching (Sussex), when I noticed that the road had been mended with some peculiar brown flints not usual in the district. . . .

Abstract:
Abstract OF the three and a half years with which we are now concerned Milton himself says nothing at all directly in the long autobiographical account in his Defensio Secunda. Though his History of Britain must have been worked on during these years, he even implies that the writing of the first four books was a labour of the single month between the publication of The Tenure of Kings (1649) and his appointment as Secretary for Foreign Languages-an unintentional deception that misled Toland and perhaps Phillips (and certainly some later biographers). Milton gives no dates; events of 1646, 1647, and 1648 are simply ignored in his narrative. It is a fair inference that he was doing little or nothing in those years that he could report later as proof of his patriotism. Yet three and a half years are a long time, and one turns expectantly to other sources of information, trusting to learn what he was studying or writing. The Commonplace Book, so suggestive for earlier periods, becomes abruptly silent; entries are extremely few. A notebook of Samuel Hartlib, dated r648, confirms what we had already inferred-that Milton had started a history of England. John Aubrey ‘s notes are of even less help; though they speak of his father ‘s age and burial in 1647, they contain not another word about these three and a half years. The anonymous biographer, although he is greatly confused about the time and sequence of certain events (e.g., the date of Mary ‘s return), does recall various happenings up to and including the burial of Milton ‘s father (15 March 1647), which he puts ‘about thirty years before ‘ the poet ‘s own death (in 1674).
