Objective and subjective measures for sleep disorders

Subjective and objective measures of sleep structure or quality could help to characterize the chronic sleep disturbances, with relation to patients＇ risk factor profiles and co-morbidities. Studies have shown that discrepancies can occur between subjective data regarding sleep disturbances and the impact of insomnia and objective assays, and surrogate markers of sleep and sleep disturbances. Both objective and subjective measures should be incorporated into clinic studies. It seems likely that sleep quality is represented by a combination of more than one subjective sleep parameter. Objective and subjective assessments of sleep quality may relate to different parameters. Future studies incorporated both subjective and objective measures could help to address the sleep disorders.

Perceptual Quality Assessment of Omnidirectional Images:Subjective Experiment and Objective Model Evaluation

Virtual reality(VR) environment can provide immersive experience to viewers.Under the VR environment, providing a good quality of experience is extremely important.Therefore, in this paper, we present an image quality assessment(IQA) study on omnidirectional images. We first build an omnidirectional IQA(OIQA) database, including 16 source images with their corresponding 320 distorted images. We add four commonly encountered distortions. These distortions are JPEG compression, JPEG2000 compression, Gaussian blur, and Gaussian noise. Then we conduct a subjective quality evaluation study in the VR environment based on the OIQA database. Considering that visual attention is more important in VR environment, head and eye movement data are also tracked and collected during the quality rating experiments. The 16 raw and their corresponding distorted images,subjective quality assessment scores, and the head-orientation data and eye-gaze data together constitute the OIQA database. Based on the OIQA database, we test some state-of-the-art full-reference IQA(FR-IQA) measures on equirectangular format or cubic formatomnidirectional images. The results show that applying FR-IQA metrics on cubic format omnidirectional images could improve their performance. The performance of some FR-IQA metrics combining the saliency weight of three different types are also tested based on our database. Some new phenomena different from traditional IQA are observed.

Influence of Subjective Knowledge, Objective Knowledge and Health Consciousness on Olive Oil Consumption—A Case Study

Unlike the case in Mediterranean countries, where olive oil consumption is driven by habit or tradition, in a population where olive oil consumption rates are considerably low, it appears reasonable to suppose that the initial decision to buy a fairly expensive product—as is the case with olive oil in the Uruguayan market—may result from an individual’s overall interest in health-related issues and/or their acquaintance with relevant nutritional properties of the particular product—in this case, olive oil. Consumer subjective and objective knowledge, interest in health-related issues, and demographic variables were studied for their potential relationship (explanatory capacity) with olive oil consumption frequency, using a sample of 256 inhabitants of Montevideo (Uruguay). Several of the studied variables were found to relate to olive oil consumption, such as subjective and objective knowledge, age, education level, marital status, and interest in health-related issues. Subjective knowledge was found to have the highest explanatory capacity. An increase in subjective knowledge is therefore expected to lead to an increase in consumption frequency among regular olive oil consumers, while it may also encourage less frequent or non-consumers to purchase olive oil and become acquainted with the product.

Efficient Spam Filtering System Based on Smart Cooperative Subjective and Objective Methods

Most of the spam filtering techniques are based on objective methods such as the content filtering and DNS/reverse DNS checks. Recently, some cooperative subjective spam filtering techniques are proposed. Objective methods suffer from the false positive and false negative classification. Objective methods based on the content filtering are time consuming and resource demanding. They are inaccurate and require continuous update to cope with newly invented spammer’s tricks. On the other side, the existing subjective proposals have some drawbacks like the attacks from malicious users that make them unreliable and the privacy. In this paper, we propose an efficient spam filtering system that is based on a smart cooperative subjective technique for content filtering in addition to the fastest and the most reliable non-content-based objective methods. The system combines several applications. The first is a web-based system that we have developed based on the proposed technique. A server application having extra features suitable for the enterprises and closed work groups is a second part of the system. Another part is a set of standard web services that allow any existing email server or email client to interact with the system. It allows the email servers to query the system for email filtering. They can also allow the users via the mail user agents to participate in the subjective spam filtering problem.

Argument Ambiguities Make Subject Relative Clause More Difficult to Process than Object Relative Clause in Mandarin

Relative clauses(RCs)processing has been a hot issue in decades.Studies from head-initial languages have found that SRCs were easier to comprehend than ORCs,and many different models were constructed to account for SRCs preference.Chinese are head-final languages and the head noun phrases are behind the internal-clause.Such a great difference in syntactic structure made Chinese to be the optimum material to test the models mentioned above.In the paper,two experiments were carried out using eye-movement tracking methods to explore the difficulty with RCs processing in mandarin,and results showed that:when the two noun phrases were both from animate category,SRCs were more difficult than ORCs,but when the noun phrases in the internal-relative-clause were inanimate and the noun phrases in the matrix were animate,the difficulties with SRCs were greatly reduced.Based on these findings,we hold that the linear syntactic distance between the gap and the filler was not the key reason to the difficulty with SRCs.On the contrary,the ambiguity in argument construction may be the most important.

Combining the Patient-Generated Subjective Global Assessment (PGSGA) and Objective Nutrition Assessment Parameters Better Predicts Malnutrition in Elderly Patients with Colorectal Cancer

Background Malnutrition is common in colorectal cancer(CRC)patients,especially in elderly patients.The Patient-Generated Subjective Global Assessment(PG-SGA)is a widely used tool developed to detect malnutrition.The aim of this study was to compare the value of the PG-SGA and objective nutrition assessment parameters,in order to identify a better predictive index for malnutrition in elderly patients with CRC.Methods A total of 131 elderly patients(age≥60 years)with CRC were included and were evaluated for their individual nutritional status using the PG-SGA.Anthropometric and serological indicators were also assayed within 48 h of admission to the hospital.Body composition analysis was implemented by bioelectrical impedance analysis(BIA)instrument.The Chi-squared test,univariate and multivariate logistic regression analysis,or Spearman’s rank correlation analysis were used to determine the differences among the above indices and parameters with regard to predicting malnutrition.Results According to the PG-SGA score,the incidence of total malnutrition in elderly patients with CRC was 80.92%(PG-SGA score≥2),which increased with age.It was found that 28%of the patients with PG-SGA classification A(PG-SGA score 0-1)had a low fat-free mass index(FFMI).Compared with those with PG-SGA A,patients with PG-SGA C PG-SGA score≥9)showed an increased neutrophil to lymphocyte ratio(NLR)and an increased platelet and lymphocyte ratio(PLR)(median=1.78 VS.2.35,P=0.015 and median=108.8 VS.141.6,P=0.001,respectively).In terms of objective nutrition assessment parameters,severely malnourished CRC patients had significantly lower values of serum albumin(ALB),and retinol conjugated protein(RBP)than those who were well-nourished[(38.35±4.84)g/L VS.(40.56±3.44)g/L,P=0.039 and(30.31±15.83)mg/L VS.(39.01±11.95)mg/L,P=0.033,respectively].The Spearman’s rank correlation analysis showed that the PG-SGA findings had positive correlations with the NLR and PLR;while it had negative correlations with the FFMI,body mass index(BMI),ALB,prealbumin,and RBP.Conclusions In clinical practice,a comprehensive nutritional diagnosis,including the PG-SGA score and these objective indicators,can avoid the underdiagnosis of malnutrition,and is more suitable to detect malnutrition(as well as its causes)in elderly patients with CRC.

In this article,I will talk about the definition and discrimination of subjective test and objective test.The strong points and weak points are also discussed.Although each has its own disadvantages,subjective test and objective test will still play important roles at present or in future.A good classroom test will usually contain both subjective and objective test items.

A Brief Report Investigating Subjective and Objective Memory Pre- and Post-Memory Training in 70- to 96-Year-Old Individuals with Mild Memory Deficit

Subjective memory impairment is a major complaint among older adults;however, research is conflicting regarding the relationship between subjective memory impairment and objectively measured memory loss. Here, individuals with mild memory impairment completed the memory subscale of the Cognistat as a measure of objective memory, and the Memory Complaint Questionnaire (MCQ) as a measure of subjective memory, prior to and following a 3-month memory training program. Results revealed that individuals with more, compared with fewer, memory complaints performed worse on the Cognistat. Additionally, increased Cognistat performance fol-lowing the memory training procedure was associated with decreased MCQ measured complaints. There was suggestive evidence that the memory training procedure improved memory, and thus future research is warranted. These findings imply that older, memory-impaired, adults, despite their memory impairment, are indeed able to judge, and may be accurately concerned with, the extent of their own memory loss. It should be noted that serious statistical limitations here indicate the need for replication to confirm the validity of the findings.

Enhancing Dense Small Object Detection in UAV Images Based on Hybrid Transformer

Transformer-based models have facilitated significant advances in object detection.However,their extensive computational consumption and suboptimal detection of dense small objects curtail their applicability in unmanned aerial vehicle(UAV)imagery.Addressing these limitations,we propose a hybrid transformer-based detector,H-DETR,and enhance it for dense small objects,leading to an accurate and efficient model.Firstly,we introduce a hybrid transformer encoder,which integrates a convolutional neural network-based cross-scale fusion module with the original encoder to handle multi-scale feature sequences more efficiently.Furthermore,we propose two novel strategies to enhance detection performance without incurring additional inference computation.Query filter is designed to cope with the dense clustering inherent in drone-captured images by counteracting similar queries with a training-aware non-maximum suppression.Adversarial denoising learning is a novel enhancement method inspired by adversarial learning,which improves the detection of numerous small targets by counteracting the effects of artificial spatial and semantic noise.Extensive experiments on the VisDrone and UAVDT datasets substantiate the effectiveness of our approach,achieving a significant improvement in accuracy with a reduction in computational complexity.Our method achieves 31.9%and 21.1%AP on the VisDrone and UAVDT datasets,respectively,and has a faster inference speed,making it a competitive model in UAV image object detection.

Masked Autoencoders as Single Object Tracking Learners

Significant advancements have beenwitnessed in visual tracking applications leveragingViT in recent years,mainly due to the formidablemodeling capabilities of Vision Transformer(ViT).However,the strong performance of such trackers heavily relies on ViT models pretrained for long periods,limitingmore flexible model designs for tracking tasks.To address this issue,we propose an efficient unsupervised ViT pretraining method for the tracking task based on masked autoencoders,called TrackMAE.During pretraining,we employ two shared-parameter ViTs,serving as the appearance encoder and motion encoder,respectively.The appearance encoder encodes randomly masked image data,while the motion encoder encodes randomly masked pairs of video frames.Subsequently,an appearance decoder and a motion decoder separately reconstruct the original image data and video frame data at the pixel level.In this way,ViT learns to understand both the appearance of images and the motion between video frames simultaneously.Experimental results demonstrate that ViT-Base and ViT-Large models,pretrained with TrackMAE and combined with a simple tracking head,achieve state-of-the-art(SOTA)performance without additional design.Moreover,compared to the currently popular MAE pretraining methods,TrackMAE consumes only 1/5 of the training time,which will facilitate the customization of diverse models for tracking.For instance,we additionally customize a lightweight ViT-XS,which achieves SOTA efficient tracking performance.

A Contrastive Study on the C-E Translation of the Verb of Perception zhijian from the Perspective of Subjective Consciousness and Objective Consciousness

Verbs of perception include sight,hearing,smell,taste and touch,of which zhijian belongs to sight is very common in literary works,and its semantic meaning also begins to change with the development of time.Based on the original text and two translated versions of the Water Margin,this paper makes a comparative analysis of the translation strategies of zhijian on the basis that Chinese emphasizes subjective consciousness and the mixed consciousness of subjectivity and objectivity,while English stresses objective consciousness with a clear boundary between subjectivity and objectivity.According to previous studies,this paper regroups the appearance of zhijian and divides it into two categories,namely zhijian at the beginning of a sentence and at the beginning of a minor sentence.On the basis of the context and the changing function of zhijian,that is,the function of being a verb and being a discourse marker,it can be concluded that as the meaning of a verb,the real action,the meaning of zhijian is expressed by“seeing”,so translators usually adopt literal translation;while as a discourse marker,it is no longer the main component of sentence structure,but to highlight the following information,translators will adopt deletion,conversion and retaining.It can be seen that translators often need to convert Chinese characterized by subjective consciousness into English dominated by objective consciousness,thus conforming to various meaning of zhijian.

What is the subject and object of social security？

The subject and the object are a pair of concepts within the philosophical category. Dialectical materialism takes practice as the medium, and holds that subject is the existence of an active objective world, and that the object is the object of practical activity. Under certain conditions, the subject and object can In terms of social security, the main body of responsibility is the government that allows the transfer of citizens＇ rights. Thereforethe government is the main body of production and providers of public goods, and the object is the main body＇s guaranteed rights and obligations. Commonly pointed objects or things generally refer to specific material information in practical operations, abstract information economy, legal norms, and the entire practice process.

Subjectivity Versus Objectivity in Teaching Foreign Language

In this paper we propose to discuss the issue of subjectivity versus objectivity teaching practice of foreign language, especially English, in Brazil. Starting from the short story ＂The Parrot and Descartes＂ by Pauline Melville, we argue that Cartesianism has influenced a view on education which tends to consider good and valuable what is ＂scientific＂, ＂objective＂ and ＂universal＂. The subjective and the local seem to be considered undesirable and unreliable. Brazilian scholars on the education field, such as Coracini and Souza are important support for our argument.

Subjectivities of the Scientific Endeavor:Noting the Illusion of Objectivity in the History of Science and Medicine

The history of science and medicine has long been steeped in the notion that they are objective(untainted by the philosophical and ideological ebbs and flows of society)and utilitarian(doing what is best for the greater good).Because of this,scientific and medical epistemologies and praxis are often held to an esteem that is unquestioned,celebrated,and occasionally unchecked.A closer look at the history of science and medicine,however,readily reveal the extent to which the milieu of society has informed scientific and medical endeavors.As such,an understanding of how the subjectivities of scientific and medical endeavors situate within our contemporary disciplines and practices is significant to one’s ability to truly understand said disciplines.Likewise,such an evaluation will provide insight into our role in perpetuating the illusion of objectivity in these fields.With this in mind,this paper provides a philosophical and historical examination of the concept of objectivity(in contrast to subjectivity)in science and medicine.

Salient Object Detection Based on a Novel Combination Framework Using the Perceptual Matching and Subjective-Objective Mapping Technologies

The integrity and fineness characterization of non-connected regions and contours is a major challenge for existing salient object detection.The key to address is how to make full use of the subjective and objective structural information obtained in different steps.Therefore,by simulating the human visual mechanism,this paper proposes a novel multi-decoder matching correction network and subjective structural loss.Specifically,the loss pays different attentions to the foreground,boundary,and background of ground truth map in a top-down structure.And the perceived saliency is mapped to the corresponding objective structure of the prediction map,which is extracted in a bottom-up manner.Thus,multi-level salient features can be effectively detected with the loss as constraint.And then,through the mapping of improved binary cross entropy loss,the differences between salient regions and objects are checked to pay attention to the error prone region to achieve excellent error sensitivity.Finally,through tracking the identifying feature horizontally and vertically,the subjective and objective interaction is maximized.Extensive experiments on five benchmark datasets demonstrate that compared with 12 state-of-the-art methods,the algorithm has higher recall and precision,less error and strong robustness and generalization ability,and can predict complete and refined saliency maps.
