![]() ![]() ![]() ![]() However, conventional MIT including thermotherapy (radiofrequency ablation 13, laser ablation 14) and cryotherapy (cryoablation 15) are intended to realize large-volume efficient therapy with over 4 mm in diameter and 5 mm in depth 3, 16, which limits the applications that require localized accurate therapy.Īlthough ultrasound-based MIT offers the opportunity for localized accurate therapy, the essential point is how to emit powerful ultrasound at the needle tip to increase the therapy efficiency. MIT possesses superior advantages for tumor therapeutics 11, 12 in liver, kidney, prostate, etc. MIT can limit the size of required incisions, localize the therapeutic region, and shorten the wound healing time, associated pain and risk of infection 9, 10. Alternatively, minimally invasive energy-based treatments (MIT) can be a promising candidate, it inserts the thin needle directly to the lesion to deliver different types of energy for treatments. Such relatively large dimensions make HIFU transducers lose certain accuracy in localized therapy for deep tissues 5, 6 and some bioeffects including side burnings (by thermal-based therapies) and significant hemorrhage (by mechanical-based therapies) 7, 8 may be potentially induced. The cigar-shaped focal dimensions are usually in the order of 1–3 mm in the transverse direction and 8–15 mm in the beam axis direction. In typical ultrasound therapeutics, High Intensity Focused Ultrasound (HIFU) treatments with the frequency of 0.75 to 3 MHz and the focal intensity of over 1 kW/cm 2 are utilized to noninvasively destruct the diseased tissue by acoustic focusing from the outside of human body. Among the medical equipment, ultrasound based medical devices have been universally recognized as the low-cost and human/environmental-friendly tool for diagnostics and therapeutics, applications mainly cover from finding the source of diseases (imaging of internal body structures) 1, 2 to treatments (tissue destruction, drug delivery, gene therapy, etc.) 3, 4. Health of human beings is always the dominant concern in the modern society, which is continuously arousing further investments and development for medical devices. Since the high-power ability at high frequencies, our waveguide will also open up new research fields in medical, bio, physics and so on. This fundamental work serves as a milestone for future biomedical applications, from therapeutics to diagnostics. High-energy-density ultrasound with around 20 times amplification by two parabolic reflectors propagates through the thin waveguide between 1 to 2 MHz, and wideband large mechanical vibration at the waveguide tip from 1 kHz to 2.5 MHz accelerates the therapeutics. Here, we invent double-parabolic-reflectors acoustic waveguides, where high-power ultrasound emission and large mechanical vibration enhance the therapeutic efficiency. Although acoustic waveguides are commonly inserted into tissue for localized therapy, powerful ultrasound delivery is difficult. However, ultrasound penetration depth is shallowed with increasing frequency which limits the therapeutic accuracy for deep tissues. High intensity focused ultrasound therapeutics are widely used to noninvasively treat various types of primary tumors and metastasis. ![]() ![]() Since this approach incurs costs for Stacks miners, they are compensated accordingly. But instead of using energy to produce new blocks, Stacks miners use bitcoin - that they need to buy at the market rate - to maintain the Stacks blockchain. In a sense, Stacks’ consensus mechanism is mimicking Bitcoin’s Proof-of-Work mechanism. However, the probability of being chosen increases with the amount of bitcoin a miner transfers to the list of Bitcoin addresses. Whichever miners get to produce a block is ultimately decided by sortition. Only by transferring Bitcoin to a predetermined randomized list of Bitcoin addresses can blocks be produced within the Stacks blockchain. So, in Stacks’ case, miners that want to mine Stacks’ native coin (STX) and participate in consensus need to send a Bitcoin transaction (containing Bitcoin units) to predefined Bitcoin addresses. With Proof-of-Transfer, this mechanism is slightly amended: The cryptocurrency used is not burned (i.e., destroyed) but distributed to a set of participants that help secure the new chain. ![]() It is their way of proving that they have incurred costs for proposing new blocks. With Proof-of-Burn, miners that participate in the consensus algorithm burn a cryptocurrency of an already established blockchain (by sending it to a burn address). Proof-of-Transfer is an adaptation of Proof-of-Burn (PoB), which was originally proposed as a consensus mechanism for the Stacks blockchain. Via this consensus mechanism, Stacks is tethered to Bitcoin by settling all Stacks transactions on Bitcoin. The key concept behind Stacks and its relation to Bitcoin is its unique consensus mechanism called Proof-of-Transfer (PoX). Various projects nowadays claim that they are building on top of Bitcoin and they all seem to be doing it differently. This way, Stacks’ entire transaction and state history is unequivocally represented on the Bitcoin base layer. This transaction records the hash of a respective Stacks block and makes sure that the Stacks block is unambiguously anchored within a block on the Bitcoin blockchain. In order to create any Stacks block, a Bitcoin transaction has to be initiated on the Bitcoin blockchain itself. In more technical terms one could say: Stacks’ entire state settles on Bitcoin. The connection to Bitcoin is established as follows: The Stacks blockchain uses the Bitcoin base-layer blockchain as a reliable storage and broadcast medium, meaning that everything that happens on Stacks (the transaction history compiled in Stacks blocks) is recorded on Bitcoin itself. Contrary to different Bitcoin sidechains, Stack’s coin (STX) is not pegged to on-chain BTC. The project has its own nodes, its own network, its own miners as well as its own coin. While this goal might be similar to that of Bitcoin sidechains, drivechains, or second-layer solutions, being a layer-1 blockchain itself, Stacks has a unique way of achieving this. In contrast to commonly known smart-contract blockchains like Ethereum, Cardano, Solana, or Avalanche, Stacks is associated with the Bitcoin ecosystem because it aims to enhance Bitcoin’s capabilities by building on top of it. This has led to the emergence of marketplaces such as StacksArt, which offer digital art secured by Bitcoin.Stacks is a layer-1 blockchain that allows for the execution of smart contracts. In recent days, Stacks has been buoyed by non fungible tokens or NFTs. In a separate Tweet, Ali explained with the help of a hand-drawn diagram how Taproot makes Bitcoin’s limited script - Bitcoin Script - and off-chain contracts more protocol efficient.Īl’s tweet was shared on Twitter by the Stacks project on Tuesday, which pointed out that Stacks has “Fully Expressive Smart Contracts.” ![]() “I'm a big supporter of Taproot,” said Ali calling it “ by far the biggest upgrade to Bitcoin that has happened over the years.” In an interview with Yahoo Finance, Stacks CEO Muneeb Ali said that he was a big supporter of Bitcoin’s “Taproot” upgrade, which took place over the weekend.

Stacks Intraday Price Movement Chart - Courtesy CoinMarketCapĪ number of key developments have taken place surrounding the Stacks project recently. ![]() ![]() ![]() Compared to others, he was one of the more centering, ecumenical figures within the broader Reformed Scholastic tradition. ![]() ![]() Peter Van Mastricht (1630-1706) is one of the most prominent Reformed systematicians from the period of High Reformed Orthodoxy, his colossal, seven-volume magnus opus, the Theoretico-practica theologica, being the largest and most comprehensive work in that style. Thus, Bramhall, with his aggressive rejection of Hobbes’ voluntarism, and his insistence on the central role of reason in human action, is, I think it safe to say, far from being a nominalist in his theological anthropology. The intellect, then, gives to human nature its moral dimension, without which, Bramhall argues, freedom and responsibility, and therefore being human, would be impossible. The chief reason for the intellect’s primacy in human action for Bramhall is its capacity to represent to the will the Good, and to move the will (morally, not efficiently) thereto: “Reason is the root of liberty in representing the good”. “Reason is the root, the fountain, the original of true liberty”, he says, “ liberty of election… is an act of judgment and understanding”. Against this view, Bramhall argued for the centrality of reason in human agency and freedom. Hobbes, the prototypical early-modern voluntarist, argued that the will, or, desire, determines the agent to his/her act. Today, Bramhall is probably most well known for his debate with Thomas Hobbes over liberty and necessity. He was a seminal figure in the Laudinization of the Irish Church, and was a frequent source of authority and inspiration for the early Tractarians. But let’s see how this hypothesis pans out with some of the major Protestant divines in their treatment of human nature and action, focusing specifically on the doctrine of free choice.īeginning with Anglicanism, John Bramhall (1594-1663), Archbishop of Armagh following James Ussher, Primate of all Ireland, and one of William Laud’s inner circle of churchmen, is one of the most celebrated of the Caroline divines. Scotus and Ockham are famous (or rather infamous, by the standards of genealogists of modernity) voluntarists during the medieval period, and Luther, Calvin, and their theological progeny, the genealogists tell us, appropriated their voluntarism in their own thought. It is usually paired against intellectualism, which, as you might have guessed, emphasizes the intellect over the will. Broadly conceived, voluntarism is any philosophical or psychological system that holds the will as primary or superordinate over the intellect. Having addressed the issue of the difference between God’s being and ours in our previous article, we will now shift our attention to the doctrine of man–that is, theological anthropology, and the genealogists’ accusation that Protestants follow the nominalists in their voluntaristic understanding of human nature. ![]() ![]() ![]() So get ready to blast off in a rocket fuelled Starfield performance preview. We also compare the improvements over the previous showing, enhancements within the engine, and much more. The biggest question after the show(s) was: why is it 30fps on Xbox Series X and Series S and not 60fps? In this IGN Performance preview, we dive into the details shared by the team, the revealed PC minimum and recommended specifications, and how the Creation Engine 2 works, comparing the previous games to gauge some of the potential reasons why the team might have chosen 30fps.

If the bone does not heal, a weak electric current applied to the bone ends (bone stimulation) may promote healing. Pins are placed in the bone, and the bone ends are held in place by pulleys and weights until union occurs. Skeletal traction may be used instead of a cast or external fixator for certain fractures, such as femoral shaft fractures. The bone may then be immobilized by external fixation until the wound heals. When the wound is clean, a sterile dressing is secured by a bandage. ![]() If the area is grossly contaminated, mild soap solution may be used provided it is thoroughly washed away with generous amounts of sterile saline. The wound is then washed and cleaned with sterile saline. Initially, the open fracture should be covered with a clean or sterile dressing and the fracture site immobilized. In open or compound fractures, bleeding must be arrested before the fracture is treated. Afterwards the limb is restored to complete function by physical therapy and exercise. The bone is kept in position by a cast or splint until union has taken place. Radiography should be used to identify the fracture and the exact position of the bone fragments. Applying a cold pack to the fracture site and elevating it above the level of the heart may limit pain and swelling. Immediate first aid includes splinting of the fracture site and joints above and below it to limit further movement and displacement. Signs include loss of the power of movement, pain with acute tenderness over the site of fracture, swelling and bruising, deformity and possible shortening, unnatural mobility, and crepitus or grating heard when the ends of the bone rub together. In a fracture due to muscular contraction, the bone breaks from a sudden, violent contraction of the muscles. In a fracture due to indirect violence, the bone is fractured by a force applied at a distance from the site of fracture and transmitted to the fractured bone, as a fracture of the clavicle by a fall on an outstretched hand. In a fracture due to direct violence, the bone breaks at the spot where the force was applied, as in fracture of a crushed tibia. ![]() In a pathological fracture, bones break, spontaneously and without trauma, due to certain diseases and conditions like cancer, osteomalacia, syphilis, and osteomyelitis.

This access is limited to the PPU license holder and other colleagues who also have a PPU license. A Power BI PPU license unlocks access to a variety of features, capabilities, and types of content that are only available through Premium. Premium per user (PPU) licenseĪ PPU per-user license provides the license holder with all of the capabilities of Power BI Pro plus access to most Premium capacity-based features. If a Power BI Premium capacity hosts the content, then Pro users can share content and collaborate with free and PPU users too. Only Power BI Pro users can publish or share content with other Pro users or consume content that's created by other Pro users, unless a Power BI Premium capacity hosts that content. Users with this license type can share content and collaborate with other Power BI Pro users. Power BI Pro is an individual per-user license that lets users create content and also read, and interact with content that others have published to the Power BI service. To learn more about features available to users with a free license, see Power BI service feature list. To learn more about workspaces, see Types of workspaces. However, Pro and PPU users can share content and collaborate with free users if the content is saved in workspaces hosted in Premium capacity. ![]() They can't use the Power BI sharing or collaborating features with others, or publish content to other people's workspaces. Users with free licenses can use the Power BI service to connect to data and create reports and dashboards for their own use. When you combine the features and capabilities of each type of per-user license with the use of a Premium capacity, that is where Pro, PPU, and free license holders gain access to additional features and capabilities - such as sharing, collaboration, and more. Each of the three per-user licenses is unique, and each grants access to certain Power BI service features and capabilities. The important distinction to understand about licenses is that there are licenses that apply to an individual (per-user) and a license (often also referred to as a subscription) that applies to the type of storage capacity that an organization purchases. A Premium Per User (PPU) workspace is not the same as a Premium capacity workspace. ![]() |
