Cross-View Action Recognition via Transferable Dictionary Learning

Discriminative appearance features are effective for recognizing actions in a fixed view, but may not generalize well to a new view. In this paper, we present two effective approaches to learn dictionaries for robust action recognition across views. In the first approach, we learn a set of view-specific dictionaries where each dictionary corresponds to one camera view. These dictionaries are learned simultaneously from the sets of correspondence videos taken at different views with the aim of encouraging each video in the set to have the same sparse representation. In the second approach, we additionally learn a common dictionary shared by different views to model view-shared features. This approach represents the videos in each view using a view-specific dictionary and the common dictionary. More importantly, it encourages the set of videos taken from the different views of the same action to have the similar sparse representations. The learned common dictionary not only has the capability to represent actions from unseen views, but also makes our approach effective in a semi-supervised setting where no correspondence videos exist and only a few labeled videos exist in the target view. The extensive experiments using three public datasets demonstrate that the proposed approach outperforms recently developed approaches for cross-view action recognition.
Greater Than Average : Optimizing a Convex Upper Bound on Top-K Loss Anonymous CVPR submission

We consider the problem of class ambiguity which is widespread in scene recognition. We argue that the topK performance metric is more sensible in that domain and propose a novel loss function, which is a convex upper bound on the top-K error. Additionally, we compare performance of various loss functions in multiclass recognition and discover that multiclass losses perform significantly better than the one-vs-all scheme. Finally, we evaluate our method on four datasets, observe consistent improvement with the proposed top-K loss, and achieve state of the art results on MIT Indoor67, SUN397, and Places 205.
Transjugular liver biopsy is safe and diagnostic for patients with congenital bleeding disorders and hepatitis C infection

Summary. The prevalence of chronic hepatitis C virus (HCV) infection among patients with severe congenital bleeding disorders is as high as 98%. Advances in HCV treatment currently result in sustained virological response rates of ≥50%. Recent recommendations have reaffirmed that liver biopsy, which provides a direct histological assessment of liver inflammation and fibrosis, is still important for accurate diagnosis and therapeutic decision making. Percutaneous liver biopsy is a simple, standardized procedure that can be performed rapidly and relatively inexpensively, and has been safely performed in patients with congenital coagulopathies. However, the safety and efficacy of the transjugular approach (transjugular liver biopsy, TJLB), recommended for patients with acquired coagulopathies, has only been minimally studied in the congenital bleeding diathesis population.
Mining Top-K Path Traversal Patterns over Streaming Web Click-Sequences

Online, one-pass mining Web click streams poses some interesting computational issues, such as unbounded length of streaming data, possibly very fast arrival rate, and just one scan over previously arrived Web click-sequences. In this paper, we propose a new, single-pass algorithm, called DSM-TKP (Data Stream Mining for Top-K Path traversal patterns), for mining a set of top-k path traversal patterns, where k is the desired number of path traversal patterns to be mined. An effective summary data structure, called TKP-forest (a forest of Top-K Path traversal patterns), is used to maintain the essential information about the top-k path traversal patterns generated so far. Experimental studies show that the proposed DSM-TKP algorithm uses stable memory usage and makes only one pass over the streaming Web click-sequences.
Domain-specific development of face memory but not face perception.

How does the remarkable human ability for face recognition arise over development? Competing theories have proposed either late maturity (beyond 10 years) or early maturity (before 5 years), but have not distinguished between perceptual and memory aspects of face recognition. Here, we demonstrate a perception-memory dissociation. We compare rate of development for (adult, human) faces versus other social stimuli (bodies), other discrete objects (cars), and other categories processed in discrete brain regions (scenes, bodies), from 5 years to adulthood. For perceptual discrimination, performance improved with age at the same rate for faces and all other categories, indicating no domain-specific development. In contrast, face memory increased more strongly than non-face memory, indicating domain-specific development. The results imply that each theory is partly true: the late maturity theory holds for face memory, and the early maturity theory for face perception.
Percentage of hypochromic erythrocytes as a potential marker of iron availability

Abstract Background: The percentage of hypochromic red cells (% Hypo-He) is now available on the Sysmex analyzer XE 5000 (Sysmex Corporation, Kobe, Japan). In this study the reliability of % Hypo-He in the assessment of iron status in the presence of inflammation is investigated. Methods: Ninety healthy subjects, 91 patients with iron deficiency anemia (IDA) previous to therapy, 65 patients with chronic kidney disease (CKD), 57 patients with anemia of chronic diseases (ACD) and 28 patients with storage iron deficiency (ACD/IDA) receiving therapy were analyzed. Pearson’s correlation, Independent samples t-test, receiver operating characteristic (ROC) curve analysis and Cohen’s k index were applied. Results: % Hypo-He values inversely correlated with the blood hemoglobin (Hb) (r=–0.78) and Hb content (MHC, r=–0.75). In patients with IDA and ACD/IDA the values obtained for % Hypo-He showed no statistical difference (p=0.5037). ROC analysis results for % Hypo-He in the detection of iron deficiency defined by a serum transferrin receptor (sTfR) >21 nmol/L. The area under the curve is 0.929; cut-off 3.6%, sensitivity 91.5% and specificity 80.9%. Using the threshold 3.6% the k index obtained in comparison to sTfR was 0.64. Conclusions: % Hypo-He is a reliable parameter for the detection of iron deficiency in patients with anemia in the presence of inflammation.
Contraception in premenopausal breast cancer patients on tamoxifen: Have you advised?

e11558 Background: Studies in women taking tamoxifen have confirmed that ovulation does occur and they can continue to menstruate during treatment. Therefore premenopausal women (PMW) taking tamoxifen are potentially at risk for pregnancy and must be counselled about barrier contraception. The risks of tamoxifen causing congenital malformations or late teratogenic manifestations in adulthood are unknown. In our center we treat hormone receptor positive breast cancer in PMW with tamoxifen. It is used in both adjuvant and palliative settings. It is a well-recognized good clinical practice to provide relevant information about the benefits and side effects of treatment to patients prior to its commencement. We undertook an audit to investigate if the issue of contraception was addressed with premenopausal breast cancer patients (PMBCP) prior to starting of tamoxifen by their oncologist. METHODS A retrospective review of 50 case notes of PMBCP was carried out. A search was conducted to find out if the clinician starting tamoxifen had advised these patients regarding contraception. Printed information and/or verbal advice given, provided they were recorded in notes, were taken as positive evidence. All patients who received tamoxifen for breast cancer in our audit had hormone receptor positive disease confirmed on histology. RESULTS See table. CONCLUSIONS In PMBCP taking tamoxifen, the issue of contraception is often not discussed and/or is poorly documented. This has potential ethical and legal implications for clinician in charge should a pregnancy occur during the treatment tenure. [Table: see text].
Parental Problem Drinking and Adolescent Psychological Problems

The primary aim of this study was to examine whether adolescent–parent communication moderates the relationship between parental problem drinking and adolescent psychological problems. Surveys were administered to a community sample of 1,001 adolescents in the spring of 2007. Results indicate that paternal problem drinking was associated with adolescent alcohol use, whereas maternal problem drinking was associated with adolescent depression. In addition, open adolescent–parent communication specifically acts as a protective factor for girls but not for boys. These results highlight the need to consider both the gender of the adolescent and the gender of the parent when examining the adolescent–parent relationship.
Xenopus oocytes reactivate muscle gene transcription in transplanted somatic nuclei independently of myogenic factors

Transplantation into eggs or oocytes is an effective means of achieving the reprogramming of somatic cell nuclei. We ask here whether the provision of gene-specific transcription factors forms part of the mechanism by which a gene that is repressed in somatic cells is transcribed in oocytes. We find that M1 oocytes have an extremely strong transcription-inducing activity. They cause muscle genes of nuclei from non-muscle somatic cells, after injection into oocytes, to be transcribed to nearly the same extent as muscle genes in muscle cells. We show, surprisingly, that the myogenic factor MyoD and other known myogenic factors are not required to induce the transcription of muscle genes in a range of non-muscle somatic cell nuclei after transplantation to Xenopus oocytes. The overexpression of Id, a dominant-negative repressor of MyoD, prevents maternal MyoD from binding to its consensus sequences; nevertheless, muscle genes are activated in somatic nuclei to the same extent as without Id. We conclude that M1 oocytes can reprogram somatic nuclei in a different way to other experimental procedures: oocytes do not suppress the transcription of inappropriate genes and they activate a gene without the help of its known transcription factors. We suggest that these characteristics might be a special property of amphibian oocytes, and possibly of oocytes in general.
YAC - A Recursive Chunker for Unrestricted German Text

YAC is a fully automatic recursive chunker for unrestricted German text. It is especially designed to provide a useful basis for the extraction of linguistic as well as lexicographic information. Consequently, the grammar rules of YAC are implemented such as to make the resulting analysis meet the needs of an ensuing extraction process. The chunks provided by YAC are continuous parts of intra-clausal constituents including recursion but no PP-attachment or sentential elements. The chunks are additionally enriched with information about head lemma, morpho-syntactic features and certain lexical and structural properties.
Multicentre Etest evaluation of in vitro activity of conventional antifungal drugs against European bovine mastitis Prototheca spp. isolates.

OBJECTIVES Bovine mammary protothecosis is a serious pathology that entails high economic losses in the dairy industry. The disease, the frequency of which has recently been increasing worldwide, is caused by unicellular, achlorophyllous, yeast-like algae of two species: Prototheca zopfii and Prototheca blaschkeae. The objective of this study was to investigate the in vitro activity of a panel of conventional antifungal drugs against Prototheca spp. isolates. METHODS A total of 144 P. zopfii genotype 2 and P. blaschkeae strains isolated from milk of mastitic cows were subjected to drug susceptibility testing by Etest methodology. RESULTS Five out of ten antifungal drugs tested exhibited no activity against Prototheca spp. isolates. The best activity against Prototheca spp. was demonstrated by amphotericin B (MIC₉₀ of 1.5 mg/L). The MICs differed significantly (P < 0.01) between P. zopfii genotype 2 and P. blaschkeae, with the latter species being more susceptible to amphotericin B and azoles. Marked differences (P < 0.05) in azole and amphotericin B activities were noted among Prototheca spp. isolates originating from different European countries. Based on the correlation coefficients, a considerable cross-interaction was found among MICs of azoles and between MICs of azoles and amphotericin B for Prototheca spp. (P < 0.03). CONCLUSIONS This study represents the largest, cross-European evaluation of antifungal activity against Prototheca spp. to date. The activity of amphotericin B against Prototheca spp. validates its potential use as a therapeutic agent against bovine protothecosis. For laboratory testing of drug activity against Prototheca spp. , the Etest method is encouraged, due to its technical simplicity, rapidity and high intra- and inter-laboratory reproducibility.
Design and testing of a four-phase fault-tolerant permanent-magnet machine for an engine fuel pump

This paper discusses the design and testing of an aircraft electric fuel pump drive. The drive is a modular, four-phase, fault-tolerant system which is designed to meet the specification with a fault in any one of the phases. The motor employed has a permanent-magnet rotor with the magnets arranged in a Halbach array to maximize the air-gap flux density. Exceptionally high electric loadings are obtained by flooding the entire motor with aircraft fuel, which acts as an excellent cooling agent. Theoretical results are compared with test results gained in conditions approaching those found in an aircraft. Tests are carried out on the unfaulted drive and with one of several fault scenarios imposed. The electrical and thermal performance of the drive is assessed, showing how the flooded fuel cooling has excellent performance without introducing significant drag on the rotor.

Evaluating the validity of clustering results based on density criteria and multi-representatives

Although the goal of clustering is intuitively compelling and its notion arises in many fields, it has been difficult to define a unified approach to address the clustering problem and thus diverse clustering approaches abound in the research community. These approaches are based on different clustering principles and assumptions and they often lead to qualitatively different results. As a consequence the results of clustering algorithms (i.e. data set partitionings) need to be evaluated as regards their validity based on widely accepted criteria. In this paper a cluster validity index, CDbw, is introduced which assesses compactness and separation of the partitions generated by a clustering algorithm. The cluster validity index, given a data set and a set of clustering algorithms, enables: i) the selection of the input parameter values that lead an algorithm to the best possible partitioning of the data set, and ii) the selection of the algorithm that provides the optimal partitioning of the data set. CDbw handles efficiently arbitrarily shaped clusters by representing each cluster with a number of points rather than by a single representative point. The properties of the validity index are theoretically justified. A full implementation and experimental results confirm the reliability of the validity index showing also that its performance compares favorably to that of several others.
Assessment of Minimum 124I Activity Required in Uptake Measurements Before Radioiodine Therapy for Benign Thyroid Diseases

This study aimed to assess a hypothetical minimum administered activity of 124I required to achieve comparability between pretherapeutic radioiodine uptake (RAIU) measurements by 124I PET/CT and by 131I RAIU probe, the clinical standard. In addition, the impact of different reconstruction algorithms on 124I RAIU and the evaluation of pixel noise as a parameter for image quality were investigated. Methods: Different scan durations were simulated by different reconstruction intervals of 600-s list-mode PET datasets (including 15 intervals up to 600 s and 5 different reconstruction algorithms: filtered-backprojection and 4 iterative techniques) acquired 30 h after administration of 1 MBq of 124I. The Bland–Altman method was used to compare mean 124I RAIU levels versus mean 3-MBq 131I RAIU levels (clinical standard). The data of 37 patients with benign thyroid diseases were assessed. The impact of different reconstruction lengths on pixel noise was investigated for all 5 of the 124I PET reconstruction algorithms. A hypothetical minimum activity was sought by means of a proportion equation, considering that the length of a reconstruction interval equates to a hypothetical activity. Results: Mean 124I RAIU and 131I RAIU already showed high levels of agreement for reconstruction intervals of as short as 10 s, corresponding to a hypothetical minimum activity of 0.017 MBq of 124I. The iterative algorithms proved generally superior to the filtered-backprojection algorithm. 124I RAIU showed a trend toward higher levels than 131I RAIU if the influence of retrosternal tissue was not considered, which was proven to be the cause of a slight overestimation by 124I RAIU measurement. A hypothetical minimum activity of 0.5 MBq of 124I obtained with iterative reconstruction appeared sufficient both visually and with regard to pixel noise. Conclusion: This study confirms the potential of 124I RAIU measurement as an alternative method for 131I RAIU measurement in benign thyroid disease and suggests that reducing the administered activity is an option. CT information is particularly important in cases of retrosternal expansion. The results are relevant because 124I PET/CT allows additional diagnostic means, that is, the possibility of performing fusion imaging with ultrasound. 124I PET/CT might be an alternative, especially when hybrid 123I SPECT/CT is not available.
SORPTION OF 99mTc RADIOPHARMACEUTICAL COMPOUNDS BY SOILS

Study of the sorption of 99mTc radiopharmaceutical compounds by soils has assessed the fate of these compounds in the event of a surface spill and examined the potential of these compounds as hydrologic tracers. Sorption from deionized water, filtered Missouri River water, and artificial seawater by five surface soils was investigated. For all water types, the Tc radiopharmaceutical compounds showed greater sorption than the uncomplexed pertechnetate. The most lipophilic complexes showed the highest sorption on soils.
Psychometric Properties of the Turkish Version of the Frontal Assessment Battery in Patients with Schizophrenia

Objectives: In this study, we aimed to test reliability and validity of the the Turkish version of Frontal Assessment Battery (FAB) in the patient with schizophrenia. Methods: The study was carried out with 47 patients with schizophrenia who were recruited from Black-Sea Technical University (BTU) and 20 healthy controls. Internal consistency and test-retest of FAB was evaluated for reliability. Separate discriminant analyses were performed using the total score of FAB and the score of individual subblocks of FAB. Concurrent validity was evaluated using Color Trail Test (CTT) and Verbal Şuency Test (VFT). Results: Criterion related to validity of the FAB was shown with significant correlation between the CTT first trial (CTT-1), CTT second trial (CTT-2), VFT on letters (VFT-L), VFT on category/animal (VFT-C) and VFT on mental control (VFT-MC) (between: 0.53-0.69). Regarding a validity of discriminating power for specific groups, the FAB showed that schizophrenic individuals performed significantly worse than healthy controls. The FAB showed acceptable test-retest reliability (r=0.71) and internal consistency (alpha: 0.65). Item total correlations were in the range 0.15 between 0.72. Conclusions: Internal reliability, test-retest and item-total score correlation, discriminating power for specific groups and criterion related to validity of the FAB indicated that the scale has acceptable reliability and validity for the patients with schizophrenia.

Strong cosmic censorship for solutions of the Einstein–Maxwell field equations with polarized Gowdy symmetry

A proof of strong cosmic censorship is presented for a class of solutions of the Einstein–Maxwell equations, those with polarized Gowdy symmetry. A key element of the argument is the observation that by means of a suitable choice of variables the central equations in this problem can be written in a form where they are identical to the central equations for general (i.e. non-polarized) vacuum Gowdy spacetimes. Using this, it is seen that the deep results of Ringström on strong cosmic censorship in the vacuum case have implications for the Einstein–Maxwell case. Working out the geometrical meaning of these analytical results leads to the main conclusion.
Entwicklung und Erträge der jüngeren empirischen Bildungsforschung

Was der Beitrag leisten will, ist eine knappe und an vielen Stellen verkurzte Ruckschau auf die Entwicklung der jungeren empirischen Bildungsforschung seit Beginn der 1990er-Jahre [. ]. Dabei soll ihr institutioneller und struktureller Ausbau berucksichtigt werden, ebenso wie eine Beschreibung und Bewertung ihrer wissenschaftlichen Ertrage, Letztere verzerrt durch die subjektive Sicht des Autors. Konzediert werden muss weiterhin, dass der Beitrag keine Gesamtdarstellung anstrebt, sondern sich vorwiegend auf zentrale, in der Fachoffentlichkeit prominente und gewissermasen strukturbildende Fordermasnahmen der Deutschen Forschungsgemeinschaft (DFG), des Bundesministeriums fur Bildung und Forschung (BMBF) und der Kultusministerkonferenz (KMK) konzentriert.
