Soil salinization is caused by spontaneous natural processes of mineral dissolution and human activities such as inappropriate irrigation practices. Natural geological progressions like weathering of rocks, arid climate, and higher evaporation, as well as anthropogenic activities, including the use of brackish water for irrigation, and poor tillage operations, are the foremost causes of soil salinization. Typical characteristics of saline soils are salt stress, high pH, and lack of organic carbon, as well as low availability of nutrients. Disruption of precipitation patterns as well as high average annual temperatures due to climate change additionally negatively affects the process of soil salinization. Productivity and ability to support crop growth are reduced on saline soil. Salinity-induced stress reduces plant growth by modulating the antioxidative system and nutrient orchestration. The aim of this work is to show that the mentioned problems can be alleviated in several ways such as the addition of biochar, exogenous application of several elicitors, seed priming, etc. Research has shown that the addition of biochar can significantly improve the recovery of saline soil. The addition of biochar has no significant effect on soil pH, while the cation exchange capacity of the soil increased by 17%, and the electrical conductivity of the saturated paste extract decreased by 13.2% (depends on the initial salinity and the type of biochar raw material). Moreover, biochar enriched with silicon increases the resistance of bananas to salt stress. In addition, exogenous application of several elicitors helps plants to alleviate stress by inducing stress-related physicochemical and molecular changes (selenium, sulfur, silicon, salicylic acid). Finally, seed priming showed positive effects on metabolomics, proteomics and growth of plants subjected to abiotic stress. Priming usually involves immersing the seed in a solution for a period of time to induce physiological and metabolic progression prior to germination.展开更多

Despite the advances, several significant challenges remain in fusing language and its nonverbal context information. One is to generate sparse attention coefficients associated with acoustic and visual modalities, which helps locate critical emotional se-mantics. The other is fusing complementary cross‐modal representation to construct optimal salient feature combinations of multiple modalities. A Conditional Transformer Fusion Network is proposed to handle these problems. Firstly, the authors equip the transformer module with CNN layers to enhance the detection of subtle signal patterns in nonverbal sequences. Secondly, sentiment words are utilised as context conditions to guide the computation of cross‐modal attention. As a result, the located nonverbal fea-tures are not only salient but also complementary to sentiment words directly. Experi-mental results show that the authors’ method achieves state‐of‐the‐art performance on several multimodal affective analysis datasets.展开更多

Applying this approach to a pedagogical agent is an essential part to enhance the effectiveness of the teaching-learning process of an intelligent learning system. This work focuses on the design of the inference engine that will give life to the interface, where the latter is represented by a pedagogical agent. The inference engine is based on an affective-motivational model. This model is implemented by using artificial intelligence technique called fuzzy cognitive maps.展开更多

The mechanical properties of the welded structures are strongly dependent on their HAZ’s width. A model based on the behaviour of the ferritic matrix of high-Si DIs in order to make an approach in measuring their HAZ’s width is developed in this study. A series of thermal treatments on 3.35 and 3.75 wt% Si as-cast DIs and spot SMAWs is applied on these materials. The applied SMAWs are done on non-preheated and preheated samples (150℃ - 300℃). For welding we modify the amperage (100 - 140A). The micro-hardness Vickers changes in the ferrite of the as-cast samples and inside the HAZ of the welded ones can be attributed to the existence of residual stresses (RS) in the ferritic matrix and assist in estimating the HAZ’s width.展开更多

文摘BACKGROUND Panic disorder(PD)involves emotion dysregulation,but its underlying mechanisms remain poorly understood.Previous research suggests that implicit emotion regulation may play a central role in PD-related emotion dysregulation and symptom maintenance.However,there is a lack of studies exploring the neural mechanisms of implicit emotion regulation in PD using neurophysiological indicators.AIM To study the neural mechanisms of implicit emotion regulation in PD with eventrelated potentials(ERP).METHODS A total of 25 PD patients and 20 healthy controls(HC)underwent clinical evaluations.The study utilized a case-control design with random sampling,selecting participants for the case group from March to December 2018.Participants performed an affect labeling task,using affect labeling as the experimental condition and gender labeling as the control condition.ERP and behavioral data were recorded to compare the late positive potential(LPP)within and between the groups.RESULTS Both PD and HC groups showed longer reaction times and decreased accuracy under the affect labeling.In the HC group,late LPP amplitudes exhibited a dynamic pattern of initial increase followed by decrease.Importantly,a significant group×condition interaction effect was observed.Simple effect analysis revealed a reduction in the differences of late LPP amplitudes between the affect labeling and gender labeling conditions in the PD group compared to the HC group.Furthermore,among PD patients under the affect labeling,the late LPP was negatively correlated with disease severity,symptom frequency,and intensity.CONCLUSION PD patients demonstrate abnormalities in implicit emotion regulation,hampering their ability to mobilize cognitive resources for downregulating negative emotions.The late LPP amplitude in response to affect labeling may serve as a potentially valuable clinical indicator of PD severity.

文摘As the frontier of intelligent computing technology,affective computing has been used in border inspection,case investigation,crime assessment,public opinion management,traffic management and other scenarios of public governance.However,there are still public risks associated with its failure to meet the basic requirements of modern public governance,and these risks are rooted in its technical characteristics.The technical characteristics of turning emotions into signals can give rise to such problems as degrading the right to informed consent,de-governance,and undermining human dignity when applied in public governance,and consequently can lead to social rights anxiety.Additionally,the affective modeling characteristics of affective computing tend to incur the rights risks of insufficient algorithm accuracy,algorithmic discrimination,and algorithmic black boxes.To avoid these risks,it is necessary to adopt the dynamic consent model as the premise for applying affective computing in public governance,and to regulate the auxiliary application of affective computing in public governance in a hierarchical manner,to achieve a balance between the application of affective computing technology and the protection of citizens'rights and the maintenance of public ethics.
文摘Affective factors and cognitive factors are two important parts of English learning, However, English teaching in recent years have taken into special consideration the necessity of knowledge and intelligence and comparatively ignored the development of affection. It may greatly reduce students＇ English learning capacity and limit the whole development of students. This paper will discuss the definition and the importance of affection and some main affective factors, and illustrate some implications of how to implement practical affective activities.
文摘To generate a further understanding of the impact of positive affective variables on foreign language learning efficiency, a theoretical analysis was conducted, from second language acquisition and cognitive psychology perspectives. Second language acquisition process is inevitably influenced by individual affective variables residing within the learner. To improve language learning efficiency, positive and facilitative affect should be enhanced in language learning.

The results show that the available B in western Jilin is in a middle level,the content in Nong'an is higher than that in the others; the available Mn is extremely abundant; the available Cu in Nong'an is obviously higher than other areas,and the content in Da'an differs greatly; the available Zn is in a middle level; the severe shortage of available Mo differs between different areas; and the available Fe is extremely abundant. The available Mn,Cu and Fe have significantly positive correlation with their total content; the available B has significantly positive correlation with pH,and Zn has obviously negative correlation with pH; the available Mn and Fe had significantly positive correlation with soil organic matter.
文摘Objective To compare the clinical therapeutic effects on scapulohumeral periarthritis between kinetic acupuncture on the distal points of the affected meridians and shoulder three-needle therapy.Methods Fifty cases of scapulohumeral periarthritis were randomly divided into an observation group and a control group,25 cases for each.The cases in observation group were treated with kinetic acupuncture on the distal points of the affected meridians.For example,the case of Hand-Taiyin type was treated with Yújì （鱼际 LU 10） and the case of Hand-Yangming type was treated with Hégǔ （合谷 LI 4）,etc.The cases in control group were treated with shoulder three-needle therapy,in which,Jiānqián （肩前 Extral）,Jiānyú （肩髃 LI 15） and Jiānliáo （肩髎 TE 14） were selected;7 days of treatment made one session,totally 2 sessions were required.Results In observation group,the curative rate based on ROM of shoulder joint was 72.0% （18/25）,which was superior to that of 40.0% （10/25） in control group （P0.05）.After treatment,the improvements of McGill SF-MPQ score,VAS and PPI in observation group were all superior to those in control group （all P0.05）.Conclusion The kinetic acupuncture on the distal points of the affected meridians is advantageous at analgesia and motor improvements of shoulder joint in treatment of scapulohumeral periarthritis as compared with shoulder three-needle therapy.
文摘This research is framed within the affective computing, which explains the importance of emotions in human cognition (decision making, perception, interaction and human intelligence). Applying this approach to a pedagogical agent is an essential part to enhance the effectiveness of the teaching-learning process of an intelligent learning system. This work focuses on the design of the inference engine that will give life to the interface, where the latter is represented by a pedagogical agent. The inference engine is based on an affective-motivational model. This model is implemented by using artificial intelligence technique called fuzzy cognitive maps.
文摘BACKGROUND A recent meta-analysis has confirmed that the effects of psychotherapy on patients with borderline personality disorders(BPD)are still insufficiently understood.Evidence of differences between different types of therapies has been questioned.AIM To study repetitive interaction patterns in patients with BPD undergoing either psychoanalysis or psychodynamic therapy.METHODS Psychoanalysis(PSA)or psychodynamic psychotherapy(PDT)was administered to 10 patients each,the two groups were matched.Therapy regimens were applied according to care as usual/manualized including quality control and supervision as usual.Randomization to one of the groups was done after baseline assessment.During classical PSA(n=10)and PDT(n=10),semiannually,recordings(audio or video)of five consecutive therapy sessions were taken over three years for an ex-post analysis.The patients'characteristics,such as affect parameters[Affect regulation and experience Q-sort(AREQ)],quality of object relations(quality of object relations scale)and personality traits[Shedler-Westen Assessment Procedure(SWAP-200)]were analyzed retrospectively by independent raters.Therapeutic action(psychotherapy process Q-sort)and affective(re)actions of the patients(AREQ)were then analyzed in relation to changes found in the patients'characteristics.RESULTS During the first year of therapy(PSA:n=10;PDT:n=9),the therapeutic method PSA was associated with significant improvements in the variable"SWAP Borderline",while in PDT change was not significantly different to baseline(PSA:P=0.04;PDT:P=0.33).Long-term results and follow up was available for seven participants in PSA and for five in PDT after three years;change in SWAP borderline for the whole sample was not significant at this time point when confronting to baseline(P=0.545).However,differences between PSA and PDT were significant when analyzing the“mean change”in the SWAP Borderline variable after one year of therapy(P=0.024):PSA led to slightly increased BPD symptoms,while PDT to a decrease;for the long run,variance of observed change was higher in PSA than in PDT(SDPSA±9.29 vs SDPDT±7.94).Our assumption that transference interpretations,closely followed by affective changes in the patient,could be useful modes of interaction was reproducible in our findings,especially when looking at the descriptive findings in the long-term data.The analysis of repetitive interaction structures demonstrated a very specific"time-lag"between therapeutic intervention and a corresponding increase in positive affect in successful therapy cases.CONCLUSION Exploring the change processes in the patients'characteristics and linking these changes to specific treatment strategies is of clinical importance when starting treatment and for its long-term progress.
文摘In English teaching and learning,listening ability is an important part of communicative competence,is a very practical integrated skill.It has been a difficult skill in second language acquisition for many students.Many Chinese students are skilled in reading,but often they tend to neglect the listening.However,owing to the higher requirements of many English tests and the great importance in communication,students begin to pay attention to develop their English listening skills.But there are many factors affecting listening,the paper mainly focuses on linguistic factors and non-linguistic factors that affect listening,to provide a theoretical basis to help exploring ways of improving listening and comprehension skills.
文摘The new curriculum standard points out that affection is one of the most important goals of fundamental education. The non-target language environment is easier to cause the affective change of middle school students who are changeable in their affective state. Based on the affective filter hypothesis, this paper deals with the adjustment to affective factors in English learning by using Internet English Curriculum Resource, such as attitude and motivation, anxiety and inhibition, self-esteem and self-confidence. At last, some suggestions are offered to judge Internet English Curriculum Resource.
文摘Shielded Metal Arc Welding (SMAW) in Ductile Irons (DI) is often required by foundries for practical manufacturing reasons. The mechanical properties of the welded structures are strongly dependent on their HAZ’s width. A model based on the behaviour of the ferritic matrix of high-Si DIs in order to make an approach in measuring their HAZ’s width is developed in this study. A series of thermal treatments on 3.35 and 3.75 wt% Si as-cast DIs and spot SMAWs is applied on these materials. The applied SMAWs are done on non-preheated and preheated samples (150℃ - 300℃). For welding we modify the amperage (100 - 140A). The micro-hardness Vickers changes in the ferrite of the as-cast samples and inside the HAZ of the welded ones can be attributed to the existence of residual stresses (RS) in the ferritic matrix and assist in estimating the HAZ’s width.
