Fis, one of the most important nucleoid-associated proteins, functions as a global regulator transcription in bacteria that has been comprehensively studied Escherichia coli K12. Fis also influences virulence Salmonella enterica and pathogenic E. by regulating their genes, however, relevant mechanism is unclear. In this report, using combined RNA-seq chromatin immunoprecipitation (ChIP)-seq technologies, we first identified 1646 Fis-regulated genes 885 Fis-binding targets S. serovar...

Abstract Synthesis of natural electric and magnetic Time series using Interstation transfer functions time from a Neighboring site (STIN) is new approach for recovering fields reduce the influence anthropogenic noise. The proposed modifies windows local that are affected by noise with resulted modifying spectra neighboring interstation between sites. STIN method was tested artificially contaminated series. Comparison STIN‐corrected original noncontaminated shows high similarity, both in...

Understanding the interactions of soil microbial species and how they responded to disturbances are essential ecological restoration resilience in semihumid semiarid damaged mining areas. Information on this, however, remains unobvious deficiently comprehended. In this study, based high throughput sequence molecular ecology network analysis, we have investigated bacterial distribution disturbed areas across three provinces China, constructed networks reveal communities diverse locations....

Space mining robots can develop and utilize abundant mineral resources in the outer space to solve problem of depletion earth resources. However, motion errors complex environments on surface asteroids greatly hinder its applications. To bridge this research gap, a precise controller robot is proposed study. Firstly, kinematics model robot’s wheels whole vehicle dynamics soft soil are established. Then, optimal PID developed based improved African vultures optimization algorithm (IAVOA). The...

Explosion suppression and isolation apparatus act as the last barrier to minimize casualties property loss. Regrettably, present techniques, such water tubs dust barriers, cannot effectively suppress multiple continuous explosions. Being a porous medium, foam ceramics are characterized with large porosity strong resistance against high temperature shocks. Theoretical analysis experimental study suggest that, due numerous collisions walls in ceramics, free radicals –generated chemical...

The spatial resolution of digital images is the critical factor that affects photogrammetry precision. Single-frame, superresolution, image reconstruction a typical underdetermined, inverse problem. To solve this type problem, compressive, sensing, pseudodictionary-based, superresolution method proposed in study. achieves pseudodictionary learning with an available low-resolution and uses the<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"...

Abstract In recent years, China has accelerated the construction of work safety laws, reformed national supervision system, and gradually upgraded its requirements standards. Since 2003, standardization been implemented to assist enterprises in identifying main responsibility safety, strengthening foundation safety. The two key objectives this paper are following: (a) analyze current status China, (b) introduce how Beijing uses local standards promote standardization. First, reviewed...

Scanning electron microscopy (SEM) plays an important role in the intuitive understanding of microstructures because it can provide ultrahigh magnification. Tens or hundreds images are regularly generated and saved during a typical imaging process. Given subjectivity microscopist's focusing operation, blurriness is distortion that debases quality micrographs. The selection high-quality micrographs using subjective methods expensive time-consuming. This study proposes new no-reference...

Abstract Due to the sensitivity of microorganisms environment, with strong tolerance in early stage coal mining collapse will gradually move a dominant position, and plants can improve soil quality provide important carbon sources for microorganisms. The characteristics response bacteria cracks during 15 ~ 20 days were studied. Compared non-cracked farmland group (C), bulk density cracked (F) increased significantly mining,while porosity was on contrary (p &lt; 0.05). mineral elements...

State-of-the-art models like OpenAI's Whisper exhibit strong performance in multilingual automatic speech recognition (ASR), but they still face challenges accurately recognizing diverse subdialects. In this paper, we propose M2R-whisper, a novel multi-stage and multi-scale retrieval augmentation approach designed to enhance ASR low-resource settings. Building on the principles of in-context learning (ICL) retrieval-augmented techniques, our method employs sentence-level ICL pre-processing...

Awareness of the value historical neighbourhoods in China's cities is growing. But how can they be successfully integrated forward‐looking plans for urban development? URBANUS, a design practice and think‐tank based Beijing Shenzhen, has been leading way finding architectural solutions to country's challenges. Hui Wang , one its co‐founders, profiles URBANUS's approach through three recent projects that have injected new life, diversity community cohesion into Beijing's hutong districts.

Purpose The purpose of this paper is to study the breather waves, rogue waves and solitary an extended (3 + 1)-dimensional Kadomtsev–Petviashvili (KP) equation, which can be used depict many nonlinear phenomena in fluid dynamics plasma physics. Design/methodology/approach authors apply Bell’s polynomial approach, homoclinic test technique Hirota’s bilinear method find KP equation. Findings results imply that equation has wave, wave solutions. Meanwhile, provide graphical analysis such...

Under investigation in this work is a generalized nonlinear equation, which can be widely applied to describe various phenomena physical science field. The equation reduced Kadomtsev–Petviashvili-type equations and Jimbo–Miwa-type as its special cases. By using Bell’s polynomial, bilinear representation well constructed. Based on the obtained formalism, we derive solitary wave solutions of equation. We also consider kinky breather wave, rational rogue by employing extended homoclinic test...

<title>Abstract</title> Background: Understanding the interactions among soil microbial species and how they responded to disturbances are essential ecological restoration resilience in semi-humid semi-arid damaged mining areas. This information, however, remains unclear poorly understood. In this study, we investigated bacterial distribution disturbed areas across three provinces of China, constructed molecular networks reveal communities different locations. Furthermore, examined...
