Partial label learning deals with the problem where each training instance is assigned a set of candidate labels, only one of which is correct. This paper provides the first attempt to leverage the idea of self-training for dealing with partially labeled examples. Specifically, we propose a unified formulation with proper constraints to train the desired model and perform pseudo-labeling jointly. For pseudo-labeling, unlike traditional self-training that manually differentiates the ground-truth label with enough high confidence, we introduce the maximum infinity norm regularization on the modeling outputs to automatically achieve this consideratum, which results in a convex-concave optimization problem. We show that optimizing this convex-concave problem is equivalent to solving a set of quadratic programming (QP) problems. By proposing an upper-bound surrogate objective function, we turn to solving only one QP problem for improving the optimization efficiency. Extensive experiments on synthesized and real-world datasets demonstrate that the proposed approach significantly outperforms the state-of-the-art partial label learning approaches.

Annotation:
In partial multi-label learning (PML), each training example is associated with multiple candidate labels which are only partially valid. The task of PML naturally arises in learning scenarios with inaccurate supervision, and the goal is to induce a multi-label predictor which can assign a set of proper labels for unseen instance. To learn from PML training examples, the training procedure is prone to be misled by the false positive labels concealed in candidate label set. In light of this major difficulty, a novel two-stage PML approach is proposed which works by eliciting credible labels from the candidate label set for model induction. In this way, most false positive labels are expected to be excluded from the training procedure. Specifically, in the first stage, the labeling confidence of candidate label for each PML training example is estimated via iterative label propagation. In the second stage, by utilizing credible labels with high labeling confidence, multi-label predictor is induced via pairwise label ranking with virtual label splitting or maximum a posteriori (MAP) reasoning. Extensive experiments on synthetic as well as real-world data sets clearly validate the effectiveness of credible label elicitation in learning from PML examples.

Graph labeling is the mapping of elements of a graph (which can be vertices, edges, faces or a combination) to a set of numbers. The mapping usually produces partial sums (weights) of the labeled elements of the graph, and they often have an asymmetrical distribution. In this paper, we study vertex–face and edge–face labelings of two-connected plane graphs. We introduce two new graph characteristics, namely the vertex–face H-irregularity strength and edge–face H-irregularity strength of plane graphs. Estimations of these characteristics are obtained, and exact values for two families of graphs are determined.

13C isotopic labeling data were obtained by 1H-observed/13C-edited magnetic resonance spectroscopy in the human brain in vivo and analyzed using a mathematical model to determine metabolic rates in human grey matter and white matter. 22,5-cc and 56-cc voxels were examined for grey matter and white matter, respectively. When partial volume effects were ignored, the measured tricarboxylic acid cycle rate was 0.72 ± 0.22 (mean ± SD) and 0.29 ± 0.09 μmol min–1 g–1(mean ± SD) in voxels of ∼70% grey and ∼70% white matter, respectively. After correction for partial volume effects using a model with two tissue compartments, the tricarboxylic acid cycle rate in pure grey matter was higher (0.80 ± 0.10 mol min–1 g–1; mean ± SD) and in white matter was significantly lower (0.17 ± 0.01 μmol min–1 g–1; mean ± SD). In 1H-observed/13C-edited magnetic resonance spectroscopy labeling studies, the larger concentrations of labeled metabolites and faster metabolic rates in grey matter biased the measurements heavily toward grey matter, with labeling time courses in 70% grey matter appearing nearly identical to labeling in pure grey matter.

Dirichlet-multinomial (D-M) mixtures like latent Dirichlet allocation (LDA) are widely used for both topic modeling and clustering. Prior work on constructing Levin-style semantic verb clusters achieves state-of-the-art results using D-M mixtures for verb sense induction and clustering. We add a bias toward known clusters by explicitly labeling a small number of observations with their correct VerbNet class. We demonstrate that this partial supervision guides the resulting clusters effectively, improving the recovery of both labeled and unlabeled classes by 16%, for a joint 12% absolute improvement in F1 score compared to clustering without supervision. The resulting clusters are also more semantically coherent. Although the technical change is minor, it produces a large effect, with important practical consequences for supervised topic modeling in general.

Annotation:
The liver is almost unique in its capacity for regeneration after hepatectomy but the exact mechanisms are not yet fully clarified. Antioxidants have been shown to promote liver regeneration after major hepatectomy. The present study evaluated the ameliorative effect of vitamin E administration on the liver regeneration after different periods of partial hepatectomy (PH) in rats. Fifty-six adult male albino rats were divided into three groups: Control sham operated group; partially hepatectomized group which were divided into three subgroups sacrificed at 1day, 3 days and 7days after the operation respectively; Partially Hepatectomized group with vitamin E pretreatment before PH where the rats were given a daily oral dose of vitamin E until the time of sacrifice of the rats. Immunohistochemical detection of proliferating cell nuclear antigen (PCNA) and labeling index were demonstrated. After PH, the PCNA positive hepatocytes and the PCNA labeling indices were significantly high after the 1st day and then much decreased after the 3rd day, to be followed by a slight increase at the 7th day. Vitamin E pretreatment in PH rats resulted in a decrease in PCNA positive cells and its labeling indices in the 1st day with a gradual increase in the 3rd and 7th days. Vitamin E has an inhibitory effect in the first 24 hours on liver regeneration followed by stimulatory effect at the third and seventh days after PH. These data indicated that vitamin E pretreatment has an important role in regulation and enhancement of liver regeneration after PH.

In multi-view multi-label learning (MVML), each training example is represented by different feature vectors and associated with multiple labels simultaneously. Nonetheless, the labeling quality of training examples is tend to be affected by annotation noises. In this paper, the problem of multi-view partial multi-label learning (MVPML) is studied, where the set of associated labels are assumed to be candidate ones and only partially valid. To solve the MVPML problem, a two-stage graph-based disambiguation approach is proposed. Firstly, the ground-truth labels of each training example are estimated by disambiguating the candidate labels with fused similarity graph. After that, the predictive model for each label is learned from embedding features generated from disambiguation-guided clustering analysis. Extensive experimental studies clearly validate the effectiveness of the proposed approach in solving the MVPML problem.

We have previously demonstrated that a plasma natriuretic factor is present in Alzheimer’s disease (AD), but not in multi-infarct dementia (MID) or normal controls (C). We postulated that the natriuretic factor might induce the increased cytosolic calcium reported in AD by inhibiting the sodium-calcium antiporter, thereby activating the apoptotic pathway. To test for a factor in AD plasma that induces apoptosis, we exposed nonconfluent cultured LLC-PK1cells to plasma from AD, MID, and C for 2 h and performed a terminal transferase-dUTP-nick-end labeling (TUNEL) assay. The plasma from AD increased apoptosis nearly fourfold compared with MID and C. The effect was dose dependent and the peak effect was attained after a 2-h exposure. Additionally, apoptotic morphology was detected by electron microscopy, and internucleosomal DNA cleavage was found. We inhibited apoptosis by removing calcium from the medium, inhibiting protein synthesis with cycloheximide, alternately boiling or freezing and thawing the plasma, and digesting a partially purified fraction with trypsin. Heating AD plasma to 56°C did not deactivate the apoptotic factor. These results demonstrate the presence of an apoptotic factor in the plasma of patients with AD.

We describe a sensitive technique for measuring long-term islet cell proliferation rates in vivo in rats. Pancreatic islets were isolated and the incorporation of deuterium (2H) from heavy water (2H2O) into the deoxyribose moiety of DNA was measured by GC-MS. The results of heavy water labeling and BrdU staining were compared. The two methods were highly correlated ( r = 0.9581, P < 0.001). Based on long-term heavy water labeling, ∼50% of islet cells divided in rats between 8 and 15 wk of age. Of interest, long-term BrdU administration suppressed proliferation of islet cells significantly, but not of bone marrow cells. Physiological evidence further supported the validity of the method: older animals (24 wk old) had 60% lower islet cell proliferation rates than younger rats (5 wk old), and partial (50%) pancreatectomy increased proliferation by 20%. In addition, cholecystokinin-8 treatment significantly stimulated proliferation in pancreatectomized rats only. In summary, heavy water labeling is a quantitative approach for measuring islet cell proliferation and testing therapeutic agents.

Annotation:
A 65-kD glycoprotein (gp65) of Trypanosoma (Duttonella) vivax was identified using a murine monoclonal antibody (mAb 4E1) that had been raised against formalin-fixed, in vitro-propagated, uncoated forms. Intracellular localization studies utilizing the mAb in immunofluorescence on fixed, permeabilized T. vivax bloodstream forms and immunoelectron microscopy on thin sections of Lowicryl K4M-embedded cells revealed labeling of vesicles and tubules in the posterior portion of the parasite. Some mAb-labeled vesicles contained endocytosed 10 nm BSA-gold after incubation of the parasites with the marker for 5-30 min at 37 degrees C, and the greatest degree of colocalization was observed after 5 min. Double labeling experiments using the mAb and a polyclonal anti-variant surface glycoprotein (VSG) antibody to simultaneously localize both gp65 and VSG demonstrated that there was little overlap in the distribution of these antigens. Thus, gp65 is associated with tubules and vesicles that are involved in endocytosis but which appear to be distinct from VSG processing pathways within the cell. Using the mAb for immunoblot analyses, gp65 was shown to be enriched in a fraction of solubilized membrane proteins eluted from either immobilized Con A or Ricinus communis agglutinin and was found to possess carbohydrate linkages cleaved by both endoglycosidase H and O-glycosidase, suggesting the presence of N- and O-linked glycans. Protease protection and crosslinking experiments suggest that gp65 is a transmembrane protein with trypsin cleavage and NH2-crosslinking sites on the lumenal face of the vesicles.

In a study often referred to as “classic,” Condry and Condry (1976) showed a videotaped infant to participants, telling half of them the infant was a boy and half it was a girl. Participants who thought they were viewing a boy rated the infant's reaction to a jack-in-the-box as anger; those who thought they were viewing a girl rated the reaction as fear. Participants in the present partial replication of the Condrys' study did not rate the infant differently based on the infant's gender label, although there was evidence that participants' own sex affects their perception of an infant's emotionality. Results were discussed in light of inconsistent results among other gender-labeling studies and relevant methodological, historical, and theoretical issues.

PURPOSE: To investigate the influence of partial colectomy associated with hepatectomy on the biodistribution of the 99mTc-phytate, on metabolic parameters, as well as labeling and morphology of red blood cells. METHODS: Wistar rats were distributed into three groups (each with six), nominated as colectomy, colectomy+hepatectomy and sham. In the 30th postoperative day all rats were injected with 99mTc-phytate 0.1mL i.v. (radioactivity 0.66 MBq). After 15 minutes, liver sample was harvested and weighed. Percentage radioactivity per gram of tissue (%ATI/g) was determined using an automatic gamma-counter. Serum AST, ALT, alkaline phosphatase and red blood cells labeling were determined. RESULTS: The liver %ATI/g and red blood cells labeling were lower in colectomy and colectomy+hepatectomy rats than in sham rats (p <0.05), and no difference was detected comparing the colectomy and colectomy+hepatectomy groups. Red blood cells morphology did not differ among groups. Serum levels of AST, ALT and alkaline fosfatase were significantly higher in colectomy+hepatectomy than in colectomy rats (p<0.001). CONCLUSION: Hepatectomy associated with colectomy lowered the uptake of radiopharmaceutical in liver and in red blood cells in rats, coinciding with changes in liver enzymatic activity.

This analytical descriptive research aims to find out the relationship between the investigated variables. These variables had been previously tested hence this study made several modifications. The data consisted of primary data and involved 150 students of Ahmad Dahlan Economics School as the respondents. The research variables were divided into exogenous variables (i.e., eco labeling, eco knowledge, green product, green packaging and green advertising) and endogenous variables (i.e., purchase intention and green customer). The data analysis technique was the Partial Least Square (PLS) by using SmartPls software. Based on the results of hypothesis testing, it can be concluded that: eco-knowledge has a significant negative influence on purchase intention; eco-knowledge has a significant negative influence on green customers; eco-labeling has a significant positive influence on purchase intention; eco-labeling has a significant negative influence on green customer; green product has a significant positive influence on purchase intention; green product has a significant positive influence on green customer; green packaging has an insignificant influence on purchase intention; green packaging has an insignificant influence on green customer; green advertising has a significant negative influence on purchase intention; green advertising has a significant positive influence on green customer; and purchase intention has a significant positive influence on green customer.

Various modifications to the immunofluorescent labeling procedures for microtubules in plant cells have been compared using cell cultures of Vicia hajastana Grossh. Using serial section electron microscopic reconstructions as a reference, we have chosen as our standard procedure a method that maximizes both the preservation of the cytoskeleton and the proportion of cells staining, while minimizing the degree of nonspecific staining. The critical steps of the procedure include stabilization of the cytoskeleton, cell wall permeabilization, and cell extraction. To maintain structural integrity during the procedure, it is necessary to stabilize the cytoskeleton with paraformaldehyde. To facilitate antibody penetration into the cell, it was necessary that the walls be made permeable via partial enzymatic digestion. Detergent extraction of cells increased the proportion of cells staining and decreased the level of nonspecific binding of the antibodies. The procedures detailed in this article provide a good starting point for the application of immunofluorescent labeling techniques to other plant systems.

To examine the role of the early changes occurring in the liver within the first hours after a partial hepatectomy and in an attempt to demonstrate the involvement of subsequent regulatory mechanisms, the size of the remnant liver was modified at various times and by different surgical techniques. Male Wistar rats were submitted to a two-thirds “temporary partial hepatectomy” produced by a 3-h occlusion of the pedicle of the anterior lobes protected by local hypothermia. Various indexes of cell proliferation ([3H]thymidine uptake and 5-bromo-2′-deoxyuridine and proliferating cell nuclear antigen labeling) were not increased despite a c- myc expression as high as that observed after a two-thirds partial hepatectomy. The temporary partial hepatectomy and a sham operation induced modifications of the hepatocytes, allowing rapid DNA synthesis after a subsequent two-thirds partial hepatectomy. After this initial nonspecific response, the extent of the regenerative response is determined according to the size of the liver mass present approximately from the 10th to the 18th hour after the initial stimulus. For instance, when a one-third partial hepatectomy was converted into a two-thirds partial hepatectomy at the 10th hour, the DNA synthesis at the 24th hour reached the value observed after a straightforward two-thirds partial hepatectomy. Inversely, the regenerative response was significantly reduced when additional liver lobes were connected to neck vessels between the 14th and the 18th hour after a two-thirds partial hepatectomy. In conclusion, the actual liver mass present during the period corresponding to mid- to late G1 appears to control the magnitude of the proliferative response, which is not the simple consequence of the early changes following a partial hepatectomy.

Semantically enhanced information retrieval (IR) is aimed at improving classical IR methods and goes way beyond plain Boolean keyword matching with the main goal of better serving implicit and ambiguous information needs. As a de-facto pre-requisite to semantic IR, different information extraction (IE) techniques are used to mine unstructured text for underlying knowledge. In this paper we present a method that combines both IE and IR to enable semantic search in natural language texts. First, we apply semantic role labeling (SRL) to automatically extract event-oriented information found in natural language texts to an RDF knowledge graph leveraging semantic web technology. Second, we investigate how a custom flavored graph traversal spreading activation algorithm can be employed to interpret user’s information needs on top of the prior-extracted knowledge base. Finally, we present an assessment on the applicability of our method for semantically enhanced IR. An experimental evaluation on partial WikiQA dataset shows the strengths of our approach and also unveils common pitfalls that we use as guidelines to draw further work directions in the open-domain semantic search field.

A face recognition method on mobile terminals based on manifold learning was proposed. Firstly, the modified Snake model was set in order to improve the accuracy and effectiveness of facial feature point labeling. Then, the partial mapping method was carried out to map the face images to a subspace for further analysis. Finally, the nearest neighbor classifier was enhanced to show the recognition results. The experimental results indicate that the performance of this method is excellent. It is boasts a higher accuracy rate and bigger robustness than the ordinary methods.

SummaryPrevious studies had shown that when gel-filtered or washed human platelets were incubated at pH 5.3, the cells secreted their granule-stored materials suggesting that low pH can act as a platelet activator. We determined here whether the effects of low pH on platelet protein phosphorylation and on platelet lipid metabolism were consistent with this view. When washed human platelets were incubated for 20 min at pH 5.3 and electrophoresed on SDS-PAGE, there was a great increase in 32P-label in the 20,000 and 47,000 dalton protein bands. There was also an increase in the labeling of phosphatidic acid and a small decrease in phosphatidyl inositol. When the platelets were returned to pH 7.6, the 32P labeling of the 20,000 and 47,000 dalton bands was greatly reduced, and that of phosphatidic acid reduced to the control value, while the labeling of phosphatidyl inositol was increased above control. Incubation at pH 5.3 for 60 min gave the same pattern, but return to pH 7.6 resulted in only partial reversal of labeling of the two protein bands and little decrease in the label associated with phosphatidic acid, but the radioactivity in phosphatidyl inositol was greatly increased. The changes in the 32P-labeling of phospholipids and proteins after incubation of platelets at pH 5.3 may reflect an increase in cytoplasmic Ca++ resulting from leakage of Ca++ from intracellular storage sites, a process which becomes irreversible after longer time exposure to the low pH. The activation of human platelets at pH 5.3 is a slow process which may not be directly comparable to the fast events in the normal stimulation-response coupling, but which is accompanied by changes common to platelet activation. Most interesting in this respect is that a return to physiological conditions will reverse these events, although prolonged exposure will make them irreversible. These studies may therefore present a way to study the boundary between reversible and irreversible processes in platelets.
