By making use of the isotope approximation; neglecting squares of relative mass differences among the isotopes, the authors derived analytically approximations to ordinary diffusion coefficients in a 3- and 4- component isotope mixture. Moreover, approximations to multi-component diffusion coefficients were given on the analogy of those to the 3- and 4-component coefficients, and these approximations were verified to satisfy constrains on the exact ordinary diffusion coefficients. For 4-component mixture of uranium hexafluoride isotopes, 234UF6-235UF6-236UF6-236UF6, composition dependences of the approximation were equal to those of the exact diffusion coefficients. In addition, relative errors between the exact and the approximations were less than 0.2% for 5-component mixture of krypton 80-82-83-84-86 isotopes.

The movable bench cultivation system is a method of increasing area productivity and minimizing the energy needed in a greenhouse. In the system, all plants pass through the same watering point every day. This point should thus be the ideal place to measure precise plant growth information. In this study, we construct an experimental system for a 3D measurement of a community of strawberries cultivated on a 1-meter-long bench. The measurement was made every two to seven days from October 23, 2013 to January 13, 2014. As a result, we obtained 31 images of 10 plant beds. The estimation error of maximum plant height ranged from −30 mm to 32 mm, and that of width ranged from −42 mm to 40 mm. To visualize the growth information effectively, a 2D histogram of the distribution of the 3D points of the plant community was also calculated.

We propose a novel user interface that enables control of a singing voice synthesizer at a live improvisational performance. The user first registers the lyrics of a song with the system before performance, and the system builds a probabilistic model that models the possible jumps within the lyrics. During performance, the user simultaneously inputs the lyrics of a song with the left hand using a vowel keyboard and the melodies with the right hand using a standard musical keyboard. Our system searches for a portion of the registered lyrics whose vowel sequence matches the current user input using the probabilistic model, and sends the matched lyrics to the singing voice synthesizer. The vowel input keys are mapped onto a standard musical keyboard, enabling experienced keyboard players to learn the system from a standard musical score. We examine the feasibility of the system through a series of evaluations and user studies.\n------------------------------This is a preprint of an article intended for publication Journal ofInformation Processing(JIP).

Background:The role of culprit plaque and related atherothrombotic components on incomplete stent apposition (ISA) occurrence after primary percutaneous coronary intervention (p-PCI) is unknown.Methods and Results:ST-segment elevation myocardial infarction (STEMI) patients undergoing p-PCI with an everolimus-eluting stent were prospectively investigated with optical coherence tomography (OCT) of the infarct-related artery before, after stenting and at 9 months. OCT data, aspirated thrombus and serum inflammatory biomarkers were analyzed. 114 patients with 114 lesions were evaluated. Acute ISA occurred in 82 lesions (71.9%), preferentially in larger vessels with a median area of 0.2 mm2. The presence of thrombus before stent implantation (odds ratio (OR) 5.5, 95% confidence interval (CI) [1.1–26.9], P=0.04) and the lipid content in the target segment (OR 1.3, 95% CI [1.0–1.5], P=0.04) independently predicted acute ISA. At 9-month follow-up, ISA persisted in 46 lesions (56.1%). The volume of acute ISA significantly predicted persistent ISA (OR 1.3, 95% CI [1.1–1.5], P=0.01). Late-acquired ISA occurred in 39 lesions (34.2%) with a median area of 0.3 mm2. Red/mixed thrombus before stent implantation (OR 3.7, 95% CI [1.0–13.3], P=0.05) and length of the underlying ruptured plaque (OR 1.7, 95% CI [1.1–2.8] P=0.02) were independently associated with late-acquired ISA.Conclusions:In STEMI patients, culprit plaque and atherothrombotic components of the infarct-related artery significantly contribute to the onset of acute and late ISA. ISA persistence at follow-up depends on the initial volume of acute ISA.

Ever since global positioning system (GPS) modules have been attached to smart phones, much research has focused on how to obtain personal trip (PT) information from them. One of the challenges is identifying activity type (or inferring the purpose of the trip) from these continuous GPS data. This paper focuses on obtaining the type of activity using several machine learning methods and comparing the results. The comparison is implemented from the perspective of accuracy and time cost in the phases of data training and prediction. After applying four machine learning methods to the data set obtained from 30 individuals in Nagoya, Japan, a classification tree method demonstrates superiority over support vector machine (SVM), neural network (NN), and discriminant analysis methods.

Background:In the setting of elective percutaneous coronary intervention (PCI), intravascular ultrasound (IVUS)-guided PCI is associated with a reduction in the incidence of target vessel revascularization (TVR), but the impact of IVUS on long-term clinical outcome in the setting of emergency PCI for ST-segment elevation acute myocardial infarction (STEMI) is still unclear.Methods and Results:The subjects consisted of 3,028 STEMI patients who underwent primary PCI within 24 h of symptom onset in the CREDO-Kyoto acute myocardial infarction registry. Of these, 932 patients (31%) underwent IVUS-guided PCI. Compared with the angiography-guided PCI without IVUS, IVUS-guided PCI was associated with significantly lower incidences of TVR (primary outcome measure; 22% vs. 27%, log-rank P<0.001) and definite stent thrombosis (ST; 1.2% vs. 3.1%, log-rank P=0.003). The cumulative incidence of all-cause death was not significantly different between the 2 groups. After adjusting for confounders, however, there were no significant differences between the 2 groups in risk for TVR (adjusted HR, 1.14; 95% CI: 0.86–1.51, P=0.38) and definite ST (adjusted HR, 0.58; 95% CI: 0.19–1.72, P=0.33).Conclusions:IVUS-guided PCI was not associated with a lower risk for TVR or ST in STEMI patients undergoing primary PCI.

The title compound, a chain adduct of rhodium(II) benzoate with 1,4-diazabicyclo[2.2.2]octane (dabco), catena(tetrakis(μ-benzoato-O,O′)(μ-1,4-diazabicyclo[2.2.2]octane-N,N′)dirhodium(II)-acetonitrile(1/4)), [Rh2(C6H5CO2)4(dabco)]n·4nCH3CN, was isolated. The crystal structure was determined by the single-crystal X-ray diffraction method at 293 K. It crystallizes in the tetragonal space group P4/n with a = 21.3695(18)Å, c = 9.6278(12)Å, V = 4396.6(8)Å3, Dx = 1.468 g/cm3, and Z = 4. The R1 [I > 2σ(I)] and wR2 (all data) values are 0.0417 and 0.0825, respectively, for all 5185 independent reflections. The molecule has a linear chain with an alternating arrangement of Rh2(C6H5CO2)4 [Rh-Rh 2.4062(11)Å, 2.4110(11)Å] and dabco. The adsorption property was confirmed for N2 gas with a specific surface area of 387.8 m2 g-1 estimated from an N2 adsorption isotherm.

We present a method for detecting on-screen markers to identify physical displays and to estimate camera poses against these displays. It is difficult for humans to perceive the variation of two alternating colors when these colors switch in a frequency higher than the flicker fusion threshold. On the other hand, the variation is detectable by of-the-shelf rolling shutter cameras which have certain frame rate setting. Leveraging on the difference between the human visual characteristics and the camera characteristics, imperceptible markers can be embedded onto a display screen. In this paper, we introduce our technique in mobile device based user interfaces for manipulating digital content on large distributed displays. Furthermore, we show that our prototype system enables an augmented reality application on a mobile device using the marker embedded displays. Lastly, we discuss potential scenarios and applications.

Little information is available regarding triple-phase computed tomography (CT) of canine pancreatic insulinoma. A few case reports with small numbers of cases have indicated that hyper-attenuation in the arterial phase was a common finding on multi-phasic CT in dogs with insulinoma. Our purpose was to clarify the characteristic findings of dogs with insulinoma on triple-phase CT. Nine dogs with insuolinoma that underwent triple-phase CT were included in the present study. Attenuation patterns in the arterial phase indicated hypo-attenuation in 4 cases and hyper-attenuation in 2 cases. In the remaining 3 cases, 1 case showed hypo-attenuation and 1 case showed hyper-attenuation in the pancreatic phase, and 1 case presented hyper-attenuation in the later phase. Altogether, 5 cases showed hypo and 4 cases showed hyper-attenuation in at least one phase. The enhancement pattern was homogenous in 7 cases and heterogeneous in 2 cases. Tumor margins were well-defined in 5 cases and ill-defined in 4 cases. Capsule formation was present in 5 cases and absent in 4 cases. In conclusion, it is important to note that hypo-attenuation was as common as hyper-attenuation in dogs with insulinoma in triple-phase CT in at least one phase. Additionally, mass lesions were most conspicuous not only in the arterial phase but in the pancreatic and later phases in some cases. Therefore, it is important to perform triple-phase CT and notice about variable findings for the detection of canine pancreatic insulinoma.

This paper is an attempt to examine the psychoanalytic method of literatureinterpretation by Sigmund Freud in Der Wahn und die Träume in W. Jensens Gradivaand intends to confirm the failures in his applied psychoanalysis. However, this paperdoes not reject psychoanalysis itself, but rather aims to highlight its theoreticalproblems and to utilize its marvelous analytic power more effectively. The method of testing this hypothesis is confronting Jensen’s Gradiva with Freud’sDer Wahn und die Träume in detail in order to emphasize the strangeness,insufficiency and forced nature of Freud’s interpretation which arises from theapplication of the theoretical apparatus of psychoanalysis. Especially it is proved withmorphological survey of images that the delusion and the dreams of the hero are notevoked by the repression of the infantile sexus but by his fascination on theembodiment of a classical ideal in a relief. Thereby this paper shows an alternativereading of Gradiva to that of Freud, and demonstrates a new interpretation on thepsychoanalytic basis.

Caffeine (1,3,7-trimethylxanthine) is a popular mild central nervous system stimulant found in the leaves, seeds and fruits of various plants and in foodstuffs such as coffee, tea, and chocolate, among others. Caffeine is widely used and is not associated with severe side effects when consumed at relatively low doses. Although rarely observed, overdoses can occur. However, only a few fatal caffeine intoxication cases have been reported in the literature. Herein, we report the pathological examination results and information on caffeine concentrations in the blood, urine and main organs in a fatal caffeine intoxication case. Even though high caffeine concentrations were found in the systemic organs, no caffeine-related pathological changes were detected.

Meta-analyses have revealed that the relative risk of hip fractures in patients with type 1 and type 2 diabetes mellitus is higher than that in non-diabetic subjects. The risk of fracture in patients with diabetes mellitus increases along with a decrease in bone mineral density (BMD) similarly to those in non-diabetic patients. However, the observed risk of fracture is higher than expected one by BMD in both type 1 and type 2 diabetic patients, indicating that precise estimation of bone fragility by BMD values in patients with diabetes is difficult. Bone strength consists of BMD and bone quality, for this reason, poor bone quality is a most suitable and explicable cause for elevated fracture risk in this population. This bone fragility observed in patients with diabetes mellitus is caused by unique pathogenesis in diabetes, suggesting that osteoporosis in diabetic patients may be one of the diabetic complications and that specific diagnostic criteria for this osteoporosis is required. Bone quality indicators closely related to bone fragility are required to be identified to establish a diagnostic method for osteoporosis in patients with diabetes mellitus.

Speech scrambling aims to eliminate intelligibility of original speech in order to preventing eavesdropping and copyright infringement. There is, however, a problem in that completely recovering scrambled speech into the original speech cannot be achieved with conventional methods. In this paper, we propose a speech scrambling method that uses the random-bit-shift of quantization bits with common keys. We evaluated the confidentiality and efficiency of the proposed method by using two objective measures, SER and PESQ. As a result we confirmed that speech signals can be scrambled into completely unintelligible sounds with the proposed method. Moreover, it is possible to restore a scrambled speech signal into the original one completely. In addition, we also confirmed that the scrambled speech signal could not be descrambled correctly with the wrong key.

Prohibitin is an antiproliferative protein that is a product of a putative tumor suppressor gene. However, there is little information on prohibitins in companion animals. In this study, we cloned canine prohibitin mRNA using RT-PCR and 3′-RACE (Rapid Amplification of cDNA Ends). The sequence was well conserved compared with those of other mammals, including human. The deduced amino acid sequence translated from the open reading frame completely corresponded to the human sequence. Canine prohibitin mRNA was expressed in all normal mammary and tumor samples examined. These results suggest that this protein plays a vital role in cell growth mechanisms and may be related to the occurrence of canine mammary tumors.
