Conservation and Renewal Strategies of Industrial Heritage Residential Areas from the Perspective of Heritage Protection : A Case Study of Residential Area of Wuchang Vehicle Factory

The residential area of Wuchang Vehicle Factory is taken as a case to explore the protection and renewal strategies of industrial heritage residential areas.By analyzing the current situation of the residential area,issues such as functional decline,memory loss,and weakened community vitality are revealed.Three design concepts are proposed:building renovation,historical space renovation,and the introduction of cultural and creative industries,aiming to improve the living environment,showcase historical value,cultivate cultural and creative industries,promote economic transformation,and community vitality.This paper could provide reference for the protection and renewal of similar industrial heritage residential areas,and new ideas for the research and utilization of industrial heritage.By comprehensively considering heritage protection,cultural inheritance,and community development,systematic suggestions are proposed.

Impacts of mixed litter decomposition from Robinia pseudoacacia and other tree species on C loss and nutrient release in the Loess Plateau of China

The productivity of Robinia pseudoacacia（R.p.） pure forest usually declines at the late growth stage,and reforming it into mixed forests could be a promising way to resolve this problem. When choosing a suitable tree species that can be mixed with R.p., the interspecific relationship is an important issue. Therefore, we gathered the autumn litter fall from R.p. and 10 other species from the Loess Plateau of China were mixed in dual species litterbags（R.p.＋each other species） and buried them in soil for a 345 days lab decay incubation. We measured the litter mass loss and nutrient contents to determine whether the nutrient release was affected by mixed species litter decomposition. The impacts of mixed litter decomposition on macro-elements release were more obvious than on micro-elements. The litters with similar substrate quality might show variable impacts on nutrients release in mixed decomposition. The C loss and release of nutrient was improved by descending order when R.p. litter was mixed with Hippophae rhamnoides, Ulmus pumila, Populus simonii, Larix principis-rupprechtii and Quercus liaotungensis（Q.l.）. But, except for Q.l., only the other species were recommended as suitable mix-plants for R.p. since promoting a high turnover of the nutrient in the litter compartment and a rapid availability for tree.

Analysis of Gene Expression Profiles of Rice Mutant SLR1 Based on Microarray Data

Gibberellins are an important class of plant hormones.They play an important regulatory role in all stages of growth and development of higher plants.The use of mutants to study gibberellin metabolism and signal transduction pathways is currently a research hotspot.This article takes the data of Affymetrix chips of rice as an example,bioinformatics method was used to study rice SLR1 mutant and mine differentially expressed wild-type genes,thus exploring the expression regulation network of gibberellin signaling pathway-related genes.

2D Part-Based Visual Tracking of Hydraulic Excavators

Visual tracking has been widely applied in construction industry and attracted signifi-cant interests recently. Lots of research studies have adopted visual tracking techniques on the surveillance of construction workforce, project productivity and construction safety. Until now, visual tracking algorithms have gained promising performance when tracking un-articulated equipment in construction sites. However, state-of-art tracking algorithms have unguaranteed performance in tracking articulated equipment, such as backhoes and excavators. The stretching buckets and booms are the main obstacles of successfully tracking articulated equipment. In order to fill this knowledge gap, the part-based tracking algorithms are introduced in this paper for tracking articulated equipment in construction sites. The part-based tracking is able to track different parts of target equipment while using multiple tracking algorithms at the same sequence. Some existing tracking methods have been chosen according to their outstanding performance in the computer vision community. Then, the part-based algorithms were created on the basis of selected visual tracking methods and tested by real construction sequences. In this way, the tracking performance was evaluated from effectiveness and robustness aspects. Throughout the quantification analysis, the tracking performance of articulated equipment was much more improved by using the part-based tracking algorithms.

Mulberry Biomass-Derived Nanomedicines Mitigate Colitis through Improved Inflamed Mucosa Accumulation and Intestinal Microenvironment Modulation

The therapeutic outcomes of conventional oral medications against ulcerative colitis(UC)are restricted by inefficient drug delivery to the colitis mucosa and weak capacity to modulate the inflammatory microenvironment.Herein,a fluorinated pluronic(FP127)was synthesized and employed to functionalize the surface of mulberry leaf-derived nanoparticles(MLNs)loading with resveratrol nanocrystals(RNs).The obtained FP127@RN-MLNs possessed exosome-like morphologies,desirable particle sizes(around 171.4 nm),and negatively charged surfaces(−14.8 mV).The introduction of FP127 to RN-MLNs greatly improved their stability in the colon and promoted their mucus infiltration and mucosal penetration capacities due to the unique fluorine effect.

Routine nasogastric tube placement in patients with small esophageal perforation after endoscopic foreign body removal may be unnecessary:a propensity score matching analysis

Background:Nasogastric tube(NGT)placement is part of the post-operative management of upper gastrointestinal perforation,but its routine use in esophageal perforation(EP)caused by foreign bodies remains unclear.The purpose of this research was to investigate the necessity for routine NGT placement in patients with EP after endoscopic foreign body removal.Methods:A total of 323 patients diagnosed with EP caused by foreign bodies at the First Affiliated Hospital of Nanchang University between January 2012 and December 2021 were included in this retrospective study.Patients were divided into the NGT group and the non-NGT group according to whether or not NGT placement was performed.The perforation healing rate,post-operative adverse events,hospital stay,and death rate were analysed using a 1:1 propensity score matching model.Results:Before matching,there were 263 patients in the NGT group and 60 patients in the non-NGT group.There were significant differences in the time to treatment,infection,albumin,and types of endoscopy between the two groups,while the length of hospital stay in the NGT group was significantly longer than that in the non-NGT group.After 1:1 propensity score matching,48 pairs of patients were matched between the two groups.The perforation healing rate,post-operative adverse events,length of hospital stay,and death rate did not show significant differences between the two groups.Conclusions:For patients with small EP caused by foreign bodies,routine NGT placement after endoscopic foreign body removal may be unnecessary.

Tuning Magnetic Relaxation in Square-Pyramidal Dysprosium Single-Molecule Magnets Using Apical Alkoxide Ligands

Eight square-pyramidal dysprosium complexes of the type[Dy(X)(DBP)_(2){TMG(H)}_(2)]were synthesized,where TMG(H)denotes 1,1,3,3-tetramethylguanidine,X denotes an alkoxide ligand or anionic guanidinate in the apical position,and DBP denotes 2,6-di-tert-butylphenoxide.These complexes,expressed as 5-Dy-X,are single-molecule magnets(SMMs)with properties dependent on the nature of the apical X ligand.

Air-Stable Dy(III)-Macrocycle Enantiomers:From Chiral to Polar Space Group

Magnetoelectric(ME)multiferroic materials have unique advantages in low-power and high-density information storage,because they can simultaneously display ferroelectricity and ferromagnetism.However,research on how to construct air-stable highperformance ME single-molecule magnets(SMMs)is nonexistent.Herein,by introducing homochirality while reducing molecular symmetry,two doubledecker Dy(III)enantiomers adopting the polar space group P2_(1) and exhibiting excellent thermal stability were obtained.They displayed zero field SMM behavior with an anisotropy barrier(Ueff)of ca.100 cm^(−1).This work establishes a rational chemical design strategy for crystallizing SMMs in polar space groups and elucidates the direction for future research,that is,engineering small-size high-performance SMMs.
