Abstract:

This work presents an information-theoretic examination of diffusion-based purification methods, the state-of-the-art adversarial defenses that utilize diffusion models to remove malicious perturbations in adversarial examples. By theoretically characterizing the inherent purification errors associated with the Markov-based diffusion purifications, we introduce LoRID, a novel Low-Rank Iterative Diffusion purification method designed to remove adversarial perturbation with low intrinsic purification errors. LoRID centers around a multi-stage purification process that leverages multiple rounds o

Abstract The solid-phase DNA probe method is a well-established technique for tRNA purification. We have applied this method for purification and analysis of other non-coding RNAs. Three columns for purification of tRNAPhe, transfer-messenger RNA (tmRNA) and 16S rRNA from Thermus thermophilus were connected in tandem and purifications were performed. From each column, tRNAPhe, tmRNA and 16S rRNA could be purified in a single step. This is the first report of purification of native tmRNA from T. thermophilus and the purification demonstrates that the solid-phase DNA probe method is applicable t

Abstract:

The path of enlightenment consists imitating of Jesus by practicing the virtues, especially the supernatural ones. The condition for this development of virtues is a some purity of heart. Man has to put his passions in order and fight with his major weaknesses. Then comes self-control, order in everyday life, deep conviction of the truths of faith, and more time to talk with the Lord during prayer. To achieve this state, a Christian must to pass a process of passive purification, which leads him into the mystical life. All imperfections must be removed. Therefore, God’s intervention is needed,

In the present paper, TiB2/Al composite with 5% volume fraction of TiB2 was fabricated by LSM method. The effects of purification and degassing methods on TiB2/Al composite were examined by means of X-ray diffraction (XRD) and image analysis. Hydrogen contents in the molten composites were detected and compared among flux, inert gas and vacuum purification processes. The experimental results indicate that under general cast condition a majority of the TiB2 particles distribute on grain boundary, and only a few particles disperse within grains. The flux and vacuum purifications have no virtual

Abstract:

Amine purification have for long been dominated by tedious stepwise processes involving the generation of large amounts of undesired waste. Inspired by recent work on out of equilibrium molecular machinery, using trichloroacetic acid (TCA), we disclose a purification technique considerably decreasing the number of operations and the waste generation required for such purifications. At first, TCA triggers the precipitation of the amines through their protonated salt formation, enabling the separation with the impurities. From these amine salts, simple decarboxylation of TCA liberates volatile C

Correlations between states in a general quantum ensemble can be encoded in a Gram matrix that depends on a prescribed joint purification. This allows to establish an upper bound for the Holevo quantity χ. Optimizing over joint purifications is a hard problem. For small ensembles the connection with matrices of fidelities is investigated. General bounds are obtained for a linearized version of χ.

Abstract:

Water Purification is often an important methodological tool in low radioactivity experiments. A variety of techniques have been exploited in the frame of the Borexino experiment to the goal of using water as a high purity shielding and as a reagent for cleaning and purification processes. This paper describes the water purification strategies and the purification results obtained in Borexino.

Abstract:

Scholars often take purification (κάθαρσις) to be a concept that persists the same throughout Plato’s dialogues. Generally, they take it to mean the separation of the soul from the body, picking up on Socrates’s account at Phaedo 67c–d. I do not find that this account of purification endures throughout the dialogues. In this paper, I argue that in Symposium Diotima describes purification differently. I argue that her account of purification emphasizes preparedness for encountering the forms, not the eradication of the corporeal. I present this account in three steps. First, I discuss Diotima’s

Abstract:

This paper presents an overview of biogas purification technology and industry status, studies the purified rules in biogas purification processing and a lot of experiments are made to verify the influence of purification efficiency by various influencing factors. Carbon dioxide in biogas, which occupies at least 30%, can be absorbed by the lye based on the acid-base neutralization reaction and the absorption efficiency can be improved by controlling the inlet pressure and other factors in the biogas purification processing. The experimental results show the purification rules that purificatio

Abstract:

The article is dedicated to the assessment of the experience in drainage water purification from radionuclides using ion-selective purification method on Units 1,2 Novovoronezh-2 NPP. Application of an ion-selective sorbent based on nickel ferrocyanide, as well as the preliminary oxidation of corrosive origin radiongjuclides, allow to achieve a satisfactory quality of purification from Cs-134, Cs-137, Co-60, Co 58, Mn-54, Cr-51. However, this method turned out to be ineffective for drainage water purification from Be-7, Sb-124, Sb-125. The article presents a possible method for drainage water

Abstract:

Aquatic plants are an effective ecological restoration method for water purification. This article reviews the importance and role of plants in water purification, and explores their research progress in the purification mechanisms of pollutants such as nitrogen and phosphorus, their impact on water ecosystems, and their applications in water pollution prevention and control. The importance and future research directions of aquatic plants in water pollution control were analyzed based on their adaptability and biodiversity. Research has found that aquatic plants have significant purification e

Marine diesel engine lubricating oil after long-term use, due to pollution and chemical activity, internal impurities increased, lubrication effect gradually deteriorated. The lubricating oil purification device based on balanced charge agglomeration (BCA) can realize the on-line purification of lubricating oil. In order to further improve the purification efficiency, a purification control system based on PLC is designed in this paper. The system consists of a complex electromechanical integration equipment composed of oil purification equipment, PLC control equipment and touch screen. The pr

Abstract:

Recently, a new simple and fast method for the synthesis of InP quantum dots by using phosphine as phosphorous precursor and myristic acid as surface stabilizer was reported. Purification after synthesis is necessary to obtain samples with good optical properties. Two methods of purification were compared and the surface processes which occur during purification were studied. Traditional precipitation with acetone is accompanied by a small increase in photoluminescence. It occurs that during the purification the hydrolysis of the indium precursor takes place, which leads to a better surface pa
