Multilevel and ampere hour accumulation are used in paper to estimate of battery, several different range discharge current improve accuracy conventional methods. The battery estimated during each cycle by measuring voltage current. salient features that no complicated measurement required method. To verify method, experiments batteries developed. experimental...

Quantum private comparison is an important topic in quantum cryptography. Recently, the idea of semi-quantumness has been often used designing protocol, which allows some participants to remain classical. In this paper, we propose a semi scheme based on Greenberge-Horne-Zeilinger (GHZ) class states, two classical compare equality their secret with help third party (server). proposed server semi-honest who will follow protocol honestly, but he may try learn additional information from...

Crowd counting is a regression task that estimates the number of people in scene image, which plays vital role range safety-critical applications, such as video surveillance, traffic monitoring and flow control. In this paper, we investigate vulnerability deep learning based crowd models to backdoor attacks, major security threat learning. A attack implants trigger into target model via data poisoning so control model's predictions at test time. Different from image classification on most...

We examined benign and malignant mesothelial tissue samples for the presence of X-linked inhibitor apoptosis protein (XIAP), a potent constituent family caspase inhibitors. subjected 55 sections (31 mesotheliomas, 2 well-differentiated peritoneal 13 pleural hyperplasias, 9 tissues) from archival formalin-fixed, paraffin-embedded surgical blocks to citrate-based antigen retrieval then incubated them with monoclonal anti-XIAP (clone 48, dilution 1:250; BD Biosciences, San Jose, CA) at 4...

Private comparison is the basis of many encryption technologies, and several related Quantum Comparison (QPC) protocols have been published in recent years. In these existing protocols, secret information encoded by using conjugate coding or orthogonal states, all users are quantum participants. this paper, a novel semi-quantum private scheme proposed, which employs Bell entangled states as resources. Two participants compare equivalence their with help semi-honest third party (TP). Compared...

The interrelation of metaphors and metonymies often attracts the attention linguists, but combination multimodal metonymies, which are important components cognition essential for creation understanding texts, has not been sufficiently studied. purpose this study is to delineate interaction between in political cartoons identify their role forming country image. research material includes 30 on topic Sino-American trade dispute 2018-2021, selected from Yandex search engine according keywords...

Abstract Carbon and low alloy steels can suffer metal loss via a synergistic erosion-corrosion mechanism in corrosive solids-containing environments. Corrosion inhibiting chemicals are frequently used to mitigate the corrosion component hydrocarbon systems. Achieving effective inhibition high velocity systems suffering from has historically been considered difficult. Furthermore, observed lesser CRA grades(1). This led some companies issuing internal guidance that limits operating conditions...

Abstract This paper reviews the development of our company’s CO2 corrosion rate prediction model and highlights some significant differences between it other models. Topics such as calculation pH, treatment fugacity, scaling, oil wetting, acetates hydraulic diameter are discussed in detail. It discusses limits, errors uncertainty associated with so that reader may be able to consider if models can really believed. The authors hope final conclusion will trusted providing user understands...

To evaluate the effects of Moisture Chamber Goggles combined with Fluorometholone eye drops on visual function and oxidative stress in patients dry disease. A retrospective analysis was conducted 80 disease treated at Ninghai First Hospital from January 2021 to May 2023. Patients were divided into a combination group (n=40, receiving Goggles) monotherapy alone) based treatment regimens. Outcomes compared between groups included subjective symptom scores (VAS), tear film stability parameters,...

A small PCR-generated DNA fragment was introduced into a pharmaceutical grade ink as molecular taggant, and the tagged delivered onto surface of capsules by standard high-speed offset printing. The amount in on each capsule is roughly 10−12 fold lower than that allowed safe United States Food Drug Administration (FDA) WHO with regards to acceptable limits residual DNA. printed sampled swabbing, followed direct analysis DNA-swab complex, without subsequent purification. It shown recovered...
