Identification of key recovering node for spatial networks

Many networks in the real world have spatial attributes, such as location of nodes and length of edges, called spatial networks. When these networks are subject to some random or deliberate attacks, some nodes in the network fail, which causes a decline in the network performance. In order to make the network run normally, some of the failed nodes must be recovered. In the case of limited recovery resources, an effective key node identification method can find the key recovering node in the failed nodes, by which the network performance can be recovered most of the failed nodes. We propose two key recovering node identification methods for spatial networks, which are the Euclidean-distance recovery method and the route-length recovery method. Simulations on homogeneous and heterogeneous spatial networks show that the proposed methods can significantly recover the network performance.

Research on Potential Energy Recovery System of 16T Wheeled Hybrid Excavator

The system translates the arm/boom/buck's potential energy into electrical energy and then the electrical energy is stored in a storage device.This study develops a set of energy management strategy to make the recoverable energy recycling efficiently.This energy of traditional excavator is lost in the form of heat energy,which is wasteful,and makes the component's temperature higher and higher to reduce the machine's life.Research on this system not only conforms to the current topic of energy crisis,but also mates with the actual engineering,so it is significant to research that.

Vacuum-Aided Recovery Technology of Spent Ni-Cd Batteries

Recovery of Ni-Cd batteries was studied by a self-designed vacuum-aided recovering system under laboratory conditions. The fundamental research on a process of disassembling and recovering selected materials from Ni-Cd batterieswas conducted. The impacts of temperature, pressure and time were studied respectively. The mechanism of vacuum thermal recovering was also discussed. The results show that: Ni-Cd batteries can be recovered effectively byvacuum-aided recovering system at 573~1173 K. At constant pressure, the increase of temperature can improve theseparating efficiency of cadmium. When the temperature is 1173 K, the cadmium can evaporate completely fromthe residue during 3 h at 10 Pa. The reduction of pressure in the certain range is effective to separate cadmium byvacuum distillation. Distillation time is a very important factor affecting separation of cadmium.

Effect of docosahexaenoic acid on the recovery of motor function in rats with spinal cord injury: a meta-analysis

Objective:Studies have shown that docosahexaenoic acid(DHA)has a beneficial effect in the treatment of spinal cord injury.A meta-analysis was used to study the effect of DHA on the neurological recovery in the rat spinal cord injury model,and the relationship between the recovery of motor function after spinal cord injury and the time and method of administration and the dose of DHA.Data source:Published studies on the effect of DHA on spinal cord injury animal models from seven databases were searched from their inception to January 2019,including PubMed,MEDLINE,EMBASE,the China National Knowledge Infrastructure,Wanfang,VIP,and SinoMed databases.The search terms included“spinal cord injury”“docosahexaenoic acid”,and“rats”.Data selection:Studies that evaluated the influence of DHA in rat models of spinal cord injury for locomotor functional recovery were included.The intervention group included any form of DHA treatment and the control group included treatment with normal saline,vehicle solution or no treatment.The Systematic Review Centre for Laboratory animal Experimentation’s risk of bias assessment tool was used for the quality assessment of the included studies.Literature inclusion,quality evaluation and data extraction were performed by two researchers.Meta-analysis was then conducted on all studies that met the inclusion criteria.Statistical analysis was performed on the data using RevMan 5.1.2.software.Outcome measures:The primary outcome measure was the score on the Basso,Beattie,and Bresnahan scale.Secondary outcome measures were the sloping plate test,balance beam test,stair test and grid exploration test.Results:A total of 12 related studies were included,3 of which were of higher quality and the remaining 9 were of lower quality.The highest mean Basso,Beattie,and Bresnahan scale score occurred at 42 days after DHA treatment in spinal cord injury rats.At 21 days after treatment,the mean difference in Basso,Beattie,Bresnahan scores between the DHA group and the control group was the most significant(pooled MD=4.14;95%CI=3.58–4.70;P<0.00001).In the subgroup analysis,improvement in the Basso,Beattie,and Bresnahan scale score was more significant in rats administered DHA intravenously(pooled MD=2.74;95%CI=1.41–4.07;P<0.0001)and subcutaneously(pooled MD=2.99;95%CI=2.29–3.69;P<0.00001)than in the groups administered DHA orally(pooled MD=3.04;95%CI=–1.01 to 7.09;P=0.14).Intravenous injection of DHA at 250 nmol/kg(pooled MD=2.94;95%CI=2.47–3.41;P<0.00001]and 1000 nmol/kg[pooled MD=3.60;95%CI=2.66–4.54;P<0.00001)significantly improved the Basso,Beattie,and Bresnahan scale score in rats and promoted the recovery of motor function.Conclusion:DHA can promote motor functional recovery after spinal cord injury in rats.The administration of DHA by intravenous or subcutaneous injection is more effective than oral administration of DHA.Intravenous injection of DHA at doses of 250 nmol/kg or 1000 nmol/kg is beneficial.Because of the small number and the low quality of the included studies,more high-quality research is needed in future to substantiate the results.

Pig farmers’ willingness to recover their production under COVID-19 pandemic shock in China-Empirical evidence from a farm survey

Pig farmers’willingness to recover production under the COVID-19 pandemic shock is significant to recover live pigs’supply in China in 2020.Increasing farmers’willingness to recover pig production contributes to enhance pig supply,stabilize the pig and pork market,and to improve pig farmers’income.This research studies the determinants of pig farmers’willingness to recover production under COVID-19 pandemic shock by applying survey data of 201 farmers in Huai’an City and Lin’an City and a logit regression model.The estimation results show that a farmer’s risk perception,the duration time of a farmer’s feed supply under COVID-19 pandemic shock,whether or not being a cooperative member,and a farmer’s knowledge on government’s policy designed to encourage pig production,a farmer’s education level and production experience are the key determinants to a farmer’s willingness to recover pig production.Thus,it’s important for policymakers to solve the problems for farmers to get access to feed during the pandemic,to encourage the development of cooperatives,as well as to issue and advocate policies to encourage pig production.The study contributes to the scant literature by providing fresh empirical evidences on determinants of farmers’willingness to recover pig production.It has significance to farmers and governments to enhance farmers’willingness to recover production,which contributes to secure pig supply in China after the COVID-19 pandemic.

Predictive Factors for Persistent Pain and Poor Recovery of Health Status 1 Year after Whiplash Injury (Quebec Grade 1 and 2): Results from the ESPARR Cohort

Background: A large number of studies have addressed whiplash injury, and many meta-analyses have sought to highlight chronicity factors;the implicated processes, however, remain a matter of debate. The present study used data from the ESPARR cohort (an on-going prospective study of a representative cohort of road accident victims in the Rh?ne administrative département of France). The objectives were to describe the consequences of whiplash injury and to determine prognostic factors for poor recovery and persistent pain at 1 year post-accident. Methods: The cohort included 255 “pure” whiplash victims, 173 of whom responded to the 1-year follow-up questionnaire. Correlations between explanatory variables and health and pain status were explored by modified Poisson regression to provide adjusted relative risk (RR) values. Results: Half of the victims had not fully recovered health status by 1 year. The main factor associated with non-recovery was pain (RR = 1.3;1.0-1.7). A birth in the family preceding the accident emerged as another factor (RR=1.5;1.2-1.9). Victims responsible for their accident were twice as likely to report being free of pain as those not responsible (RR = 0.5;0.3-0.8). No correlation emerged with accident-related characteristics or PTSD. Conclusions: The present results extend our understand- ing of whiplash injury. Residual pain is the fundamental factor causing whiplash victims to feel that they have not recovered good health. Our findings suggest this may be bound up with physical factors (gender susceptibility);external factors such as having to carry weights (such as a baby) and with perceiving oneself as a victim are not incompatible with this hypothesis.
