Blind image super-resolution (blind SR) aims to restore a high-resolution (HR) image from a low-resolution (LR) image with unknown degradation. Many existing methods explicitly estimate degradation information from various LR images. However, in most cases, image degradations are independent of image content. Their estimations may be influenced by the image content resulting in inaccuracy. Unlike existing works, we design a dual-encoder for degradation representation (DEDR) to preclude the influence of image content from LR images. This benefits in extracting the intrinsic degradation represen

Animal waste represents a&nbsp;significant threat to the environment. Degradation of waste from dead animals is in general carried out in specialized facilities (rendering plants) under specific rules and guidelines. In plant proximity, undesirable malodour is usually produced during the combustion process. This odour can be effectively reduced so that it does not negatively affect the environment and society. Degradation of animal waste malodour can be processed in ozonisers, thermal combustion devices or in bio washers. The purpose of this paper is to determine the limits of exhausts tha

All living cells regulate the content and composition of their resident proteins, but the mechanisms by which this is accomplished are not understood. The process of protein degradation has an important role in determining steady state and fluctuations of protein concentrations in mammalian cells. This process may be regulated by innate properties of the protein substrates, by factors that interact or "brand" proteins for degradation or by the degradative machinery of the cell. For a specific protein, there appears to be a committed step, an irreversible event that leads to rapid and extensive

Emerging high-quality face restoration (FR) methods often utilize pre-trained GAN models (i.e., StyleGAN2) as GAN Prior. However, these methods usually struggle to balance realness and fidelity when facing various degradation levels. Besides, there is still a noticeable visual quality gap compared with pre-trained GAN models. In this paper, we propose a novel GAN Prior based degradation-aware feature interpolation network, dubbed Panini-Net, for FR tasks by explicitly learning the abstract representations to distinguish various degradations.

Medical stents are tubes made of a metal or plastic wire mesh. They are inserted into a hollow structure of a body part to keep an anatomic vessel or passageway open. Stents placed in the body can cause toxic effects by releasing metal ions into the body, and can also cause harmful effects on the body by creating corrosion products. In this study, the decomposition rate and release of corrosion products in artificial body fluid (PBS) of a stent sample with a nitinol structure produced for medical purposes were examined.

Abstract: Heat treatment of inulin at 135 to 190°C leads to a decrease in the measurable amount of the fructan, when quantified as fructose after enzymatic hydrolysis. Using high-performance anion-exchange chromatography with pulsed amperometric detection, degradation of the fructan chains and concomitant formation of low-molecular products was observed, most likely representing di-D-fructose dianhydrides. Heat-induced degradation of inulin during thermal processing of foods like bakery products must be taken into account within the discussion about possible prebiotic properties of the fructan

Degradation and axial deformations of railway ballast bed are highly influenced by stresses induced by moving trains. Hence, this study evaluate the influence of train axle load on the rate of degradation and axial deformation of railway ballast bed. Series of cyclic loading test were conducted at intervals of 200,000 load cycles up to 1,000,000 cycles. Two trains with capacities of 30 ton and 24 tons for freight and passengers respectively were simulated at a typical moving speed of 120 km/hr which is equivalent to a frequency of 16.5 Hz. It was observed that with an increase in both axle loa

Recently, microplastics have emerged as a major environmental pollutant and have been documented globally. Several studies have shown that microplastics can accumulate heavy metals and persistent organic pollutants as they pass through the environment due to their functional groups interacting with and complex these substances. While conventional wastewater treatment methods can reduce a significant amount of microplastics, many still make their way into rivers and oceans worldwide from their effluents. One of the promising approaches to wastewater cleaning is photocatalysis. Although it has d

The degradation rate of 3-hydroxy-3-methylglutaryl CoA reductase (HMG-R), a key enzyme of the mevalonate pathway, is regulated through a feedback mechanism by the mevalonate pathway. To discover the intrinsic determinants involved in the regulated degradation of the yeast HMG-R isozyme Hmg2p, we replaced small regions of the Hmg2p transmembrane domain with the corresponding regions from the other, stable yeast HMG-R isozyme Hmg1p. When the first 26 amino acids of Hmg2p were replaced with the same region from Hmg1p, Hmg2p was stabilized. The stability of this mutant was not due to mislocalizati

This article focuses on the effect of the heavy ions irradiations on the electrical characteristics of VDMOSFET (Vertical Diffusion Metal Oxide Semiconductor Field Effect Transistor) devices. A summary of the total dose effects and the single event effects is covered to evaluate the experimental observations. Device degradations due to the hot carriers junction avalanche are studied by a physical parameters extraction method, leading to an understanding of the degradation processes. Results show that a protective resistor load can reduce the degradation effect in the device.

In the Langendorff isolated perfused rat heart, 36% of total basal protein degradation was inhibited by the lysosomal inhibitor chloroquine (30 microM), after elimination of rapid turnover proteins during a 3 h preliminary degradation period. Prior inhibition of degradation with chloroquine was additive to the 30% inhibition caused by simultaneous infusion of 50-200 nM-isoprenaline. This additivity suggests that the adrenergic-controlled process is independent of the lysosomal degradative pathway. After discontinuation of drug infusions, the isoprenaline-inhibited degradation rate returned to

Alveolar macrophages degrade surfactant protein (SP) A and saturated phosphatidycholine [dipalmitoylphosphatidylcholine (DPPC)]. To clarify this process, using rabbit alveolar macrophages, we analyzed the effect of drugs known to affect phagocytosis, pinocytosis, clathrin-mediated uptake, caveolae, the cytoskeleton, lysosomal pH, protein kinase C, and phosphatidylinositol 3-kinase (PI3K) on the degradation of SP-A and DPPC. We found the following: 1) SP-A binds to the plasma membrane, is rapidly internalized, and then moves toward degradative compartments. Uptake could be clathrin mediated, wh

Autonomous driving plays a crucial role to prevent accidents and modern vehicles are equipped with multimodal sensor systems and AI-driven perception and sensor fusion. These features are however not stable during a vehicle’s lifetime due to various means of degradation. This introduces an inherent, yet unaddressed risk: once vehicles are in the field, their individual exposure to environmental effects lead to unpredictable behavior. The goal of this paper is to raise awareness of automotive sensor degradation. Various effects exist, which in combination may have a severe impact on the AI-base

Abstract This work investigates the efficiency of LED and UV-C photo-reactors for paracetamol degradation using advanced oxidative processes. Among the evaluated processes, photo-Fenton was the most efficient for both radiations. Degradations greater than 81% (λ 197 nm) and 91% (λ 243 nm) were obtained in the kinetic study. These degradations were also observed by means of the reduction in the peaks in both spectral scanning and high-performance liquid chromatography analysis. The good fit of the Chan and Chu kinetic model shows that the degradation reaction has pseudo-first order behavior. To

ABSTRACT In order to see if the biodegradative pathways for morpholine and thiomorpholine during degradation by Mycobacterium aurumMO1 could be generalized to other heterocyclic compounds, the degradation of piperidine by this strain was investigated by performing1H-nuclear magnetic resonance directly with the incubation medium. Ionspray mass spectrometry, performed without purification of the samples, was also used to confirm the structure of some metabolites during morpholine and thiomorpholine degradation. The results obtained with these two techniques suggested a general pathway for degrad
