AbstractHumans regularly interact with their surrounding objects. Such interactions often result in strongly correlated motions between humans and the interacting objects. We thus ask: “Is it possible to infer object properties from skeletal motion alone, even without seeing the interacting object itself?” In this paper, we present a fine-grained action recognition method that learns to infer such latent object properties from human interaction motion alone. This inference allows us to disentangle the motion from the object property and transfer object properties to a given motion. We collected a large number of videos and 3D skeletal motions of performing actors using an inertial motion capture device. We analyzed similar actions and learned subtle differences between them to reveal latent properties of the interacting objects. In particular, we learned to identify the interacting object, by estimating its weight, or its spillability. Our results clearly demonstrate that motions and interacting objects are highly correlated and that related object latent properties can be inferred from 3D skeleton sequences alone, leading to new synthesis possibilities for motions involving human interaction.

The present study investigated what complaints are prominent in psychologically distressed Vietnamese in Vietnam beyond standard symptoms assessed by Western diagnostic instruments for anxiety and depression. To form the initial Vietnamese Symptom and Cultural Syndrome Addendum (VN SSA), we reviewed the literature, consulted experts, and conducted focus groups. The preliminary VN SSA was then used in a general survey (N = 1004) of five provinces in Vietnam. We found that the VN SSA items were highly and significantly correlated with a measure of anxious-depressive psychopathology (a composite measure of the General Anxiety Disorder-7; Posttraumatic Diagnostic Scale; and Patient Health Questionnaire-9). The VN SSA item most highly correlated to anxious-depressive psychopathology was “thinking a lot” ( r = .54), reported by 15.8% of the sample. Many other symptoms in the addendum also were prominent, such as orthostatic dizziness (i.e., dizziness upon standing up; r = .41), reported by 22.9% of the sample. By way of comparison, somatic complaints more typically assessed to profile Western anxious-depressive distress, such as palpitations, were less prominent, as evidenced by being less strongly correlated to Western psychiatric symptoms and being less frequent (e.g., palpitations: r = .31, 7.1% of the sample). Study results suggest that to avoid category truncation when profiling anxious-depressive distress among Vietnamese that items other than those in standard psychopathology measures should also be assessed.

The Relationship

1. By establishing the relationship between linear carcass measurements and the quantitative composition of the carcass in terms of bone, muscle and fat, we have provided a scientific basis for the use of many measurements hitherto only presumed to provide an index to carcass quality.2. External carcass measurements are correlated with weight of the skeleton. The most useful for this purpose are length of tibia + tarsus and length of the fore-cannon.3. As indices of muscle, external measures are only of indirect value. Thus, both F – T and G/F × 100 are strongly correlated with weight of muscle as a percentage of skeletal weight.4. Similarly, F provides an index of fat, being negatively correlated with fat as a percentage of bone.5. For muscle and fat internal measures permit a more precise estimate to be made. A + B is the best index of the former while C + J + Y provide the most accurate estimate of the weight of fat.6. Still better indices for muscle and fat are provided by suitable combinations of external and internal measurements. Thus L/10 + A + B is very highly correlated with the weight of muscle, and L/10 × (C + J + Y) is the best index of fat in the hoggets. For bone, a most efficient single index is shown to be the weight of the fore-cannon bone.7. The weight of the skeleton can be estimated with a high degree of accuracy from the weight of the bones in either one leg or loin. Both these joints combined, however, provide a still better estimate.8. The muscle in one leg or loin + leg provides an excellent index of the weight of muscle in the whole carcass.9. The fat in one leg, loin, or both these joints combined provides a good index of the weight of the total fat in the carcass. Both joints combined give the most precise measure.10. The value of certain measurements which are not necessarily associated with the quantity of the major tissues of the carcass, but which nevertheless have important qualitative significance, is emphasized.

Sampling Times

The concentration of NH4-N, NO3-N and their sum (mineral N) were monitored 12 times in 1 or 2 weekly intervals in the soil under a sweet corn crop. The samples were taken on the fertilizer band and to depths of 200, 400 and 600 mm. The NO3-N concentration of the sap expressed from the midrib of the leaf opposite and immediately above the primary cob (sap NO3-N) and that of midrib dry matter (midrib NO3-N) were determined weekly. Under the low rainfall and optimized irrigation of this trial the concentration of mineral N in soil to the depth of 400 mm or more was a good predictor of yield response to application of N at 10 of the 12 sampling times. The concentration of either NH4-N or NO3-N in the soil to any depth and the concentration of mineral N in the surface 200 mm correlated with the yield at only a few times of sampling. The concentration of mineral N in the top 200 mm of soil 1 or 2 weeks after top-dressing of N was highly correlated to yield. The concentration of sap NOS-N and midrib NO3-N decreased continuously until harvest. Both these concentrations were significantly correlated with the rates of basal and top-dressed N in most sampling times. These were also strongly correlated to yield 1 or 2 weeks after N top-dressing. Ammonium sulfate, ammonium nitrate and urea gave similar responses in sap NO3-N and midrib NO3-N and in soil nitrogen after 5 weeks when nitrification of fertilizer NH4-N was complete. These observations indicated that soil mineral N, sap NO3-N and midrib NO3-N all offer potential as techniques to predict the yield response of sweet corn to N application. The sap NO3-N test was simpler, quicker, cheaper and more consistent than other tests.

Abstract The rule of law research agenda is in many ways still in its infancy. This is reflected, inter alia, in the fact that no attempt has been made to investigate the empirical relationship between sub-components of the rule law. In this article, we set out to make such an appraisal. We take our cue from a recent attempt to get at this relationship with a typology of ‘defective’ subtypes of the rule of law. Insofar as the underlying radial logic characterizes the relationship between constituent units of the rule of law, it would mean that countries tend to be situated in a range of so-called diminished subtypes, i.e., combinations defined by the presence of all attributes save one. The upshot of this is that we cannot simply aggregate the sub-component scores into composite indices. However, our analyses show that the scores on different rule of law attributes are highly correlated and that – if less fine-grained distinctions are used – cases tend to be characterized by either the presence of all attributes, by moderate scores on all attributes, or by severe shortcomings in every regard. These findings can be taken to support, first, that the value of constructing diminished subtypes of the rule of law is limited, and, second, that the creation of composite measures by aggregating across the rule of law subcomponents is not hampered by multidimensionality. At the end of the article, we use the extant literature on democratization and state formation to identify some potential reasons for the high co-variation between rule of law attributes.

Tax Changes

Tax competition is the quintessential example of policy interdependence. The general idea is that tax changes in one jurisdiction lead to similar changes in others. However, research has shown that institutional and political constraints limit competition. This article develops another argument: that socialization among policy makers attenuates competitive dynamics by setting limits to the extent of competition that is considered acceptable. Using fine-grained Swiss data and spatial econometric techniques, it shows that personal income tax rates are more strongly correlated among competitors that do not participate in the same intergovernmental organizations. This finding implies that, to some extent, the detrimental consequences of competition can be mitigated by fostering institutionalized forms of interaction among policy makers.

AbstractObjectiveTo assess the relative validity and repeatability of a sixty-four-item FFQ for estimating dietary intake of Zn and its absorption modifiers in Saudi adults. In addition, we used the FFQ to investigate the effect of age and gender on these intakes.DesignTo assess validity, all participants completed the FFQ (FFQ1) and a 3 d food record. After 1 month, the FFQ was administered for a second time (FFQ2) to assess repeatability.SettingJeddah, Saudi Arabia.SubjectsOne hundred males and females aged 20–30 years and 60–70 years participated.ResultsMean intakes of Zn and protein from FFQ1 were significantly higher than those from the food record while there were no detectable differences between tools for measurement of phytic acid intake. Estimated intakes of Zn, protein and phytate by both approaches were strongly correlated (P<0·001). Bland–Altman analysis showed for protein that the difference in intake as measured by the two methods was similar across the range of intakes while for Zn and phytic acid, the difference increased with increasing mean intake. Zn and protein intakes from FFQ1 and FFQ2 were highly correlated (r>0·68,P<0·001) but were significantly lower at the second measurement (FFQ2). Older adults consumed less Zn and protein compared with young adults. Intakes of all dietary components were lower in females than in males.ConclusionsThe FFQ developed and tested in the current study demonstrated reasonable relative validity and high repeatability and was capable of detecting differences in intakes between age and gender groups.

Abstract Recognizing irregular text in real industrial scenes is a challenging task due to the background clutter, low resolutions or distortions. In this work, an attention-based text detection and recognition method for terminals of current transformer’s secondary circuit is proposed. It consists of three major components: pre-processing, text detection and text recognition. In text recognition module, a novel spatial temporal embedding is designed to better utilize the positional information. During training, the proposed framework only requires sequence-level annotations, instead of extra fine-grained character-level boxes or segmentation masks as in previous work. Despite its simplicity, the proposed method achieves good performance on the dataset collected in actual working scene.

Several fitness watches have developed tests to estimate VO2max to provide important data and save money by reducing the need for a metabolic cart. Some watches provide results based on heart rate (HR) while others combine HR data with global positioning satellite (GPS) data. The purpose of this study was to validate VO2max from the fitness test on a Garmin Forerunner 920XT (HR and GPS-based) and a Polar RS300X (HR-based) fitness watch against a maximal graded exercise test (GXT) using a metabolic cart. 10 male and 7 female college students (age = 21.5 ± 2.9 years) participated in this study. Session 1 consisted of completing the Informed Consent, PAR-Q, and Garmin fitness test. Session 2 comprised the Polar fitness test and a maximal Bruce treadmill test using the metabolic cart. Maximal performance during the Bruce test was validated by obtaining age-predicted HRmax. Data were analyzed using one-way ANOVA with a significance level of p < 0.05. Secondary analysis was conducted using Pearson correlations. VO2max from the Garmin, Polar, and metabolic cart tests were 47.82 (± 9.60), 45.53 (± 5.42), and 45.63 (± 8.84) ml/kg/min, respectively. ANOVA tests revealed no significant differences between any of the tests (p = 0.6 between the Garmin and the metabolic cart; p = 0.3 between the Polar and the metabolic cart). Pearson correlations revealed that the Garmin test was highly correlated with r = 0.83 (p < 0.001) while the Polar test was strongly correlated (r = 0.65, p < 0.001). The findings indicate that Garmin and Polar fitness tests may serve as an adequate substitute for testing using a metabolic cart. The Garmin test may be a more appropriate choice as the correlation was stronger and the Polar test tended to overestimate VO2max.
