Development of Dynamic Pressure Generator Using Rotating Valve (1998)

In order to generate precise dynamic pressure, we are developing a dynamic pressure generator using a newly rotating valve. This paper describes the principle of the valve and the generator and some experimental results. The generated waveform is square whose amplitude and fundamental frequency can be changed. When the supplied difference pressure was 5kPa and the fundamental frequency was changed from 1 to 100Hz, we measured the waveform by a pressure transducer, and evaluated the amplitude and the mean value of the waveform. As an experiment result, the amplitude and the mean value of the generated pressure were almost constant in the frequency range from 1Hz to 50Hz.

Sebaceous Epithelial-Myoepithelial Carcinoma of the Salivary Gland: Clinicopathologic and Immunohistochemical Analysis of 6 Cases of a New Histologic Variant (2008)

Epithelial-myoepithelial carcinoma (EMC) of the salivary glands is an uncommon, low-grade malignant tumor. A recent report demonstrates sebaceous differentiation in this tumor even though its significance has never been documented as a precise histologic variant. Six cases of EMC exhibiting sebaceous differentiation (sebaceous EMC) of the parotid gland were analyzed for their clinicopathologic features and immunohistochemical characteristics. In addition, primary salivary sebaceous carcinomas were also examined for comparison. In our series, the incidence of sebaceous EMC was 0.2% among 3012 cases of parotid gland tumors and 14.3% of all EMC cases. The 6 patients comprised 2 men and 4 women, age ranging from 77 to 93 years (mean, 83.7 y). Neither cervical lymph node nor distant organ metastases were found in any cases of sebaceous EMC and no patients died of disease, though local recurrences developed in 1 patient. Conversely, cervical lymph node metastasis was detected in 2 of 3 patients with sebaceous carcinoma, 1 of whom died of disease at 12 months. Histologically, all 6 tumors had an area of sebaceous differentiation admixed with features of bilayered ductal structures typical of EMC. A component of sebaceous differentiation was distributed diffusely in 4 tumors and focally in 2. Cytologic atypia of sebaceous EMCs was lesser than that of sebaceous carcinomas. Immunohistochemically, putative myoepithelial markers such as alpha-smooth muscle actin, calponin, p63, cytokeratin 14, S-100 protein, and vimentin were highly expressed in sebaceous EMC. However, the expression of the latter 4 markers was also observed in primary sebaceous carcinomas, whereas these tumors were all negative for alpha-smooth muscle actin and calponin. Positive immunoreactivity for epithelial membrane antigen, adipophilin, and perilipin confirmed sebaceous differentiation in EMC. These results indicate that sebaceous EMC is a low-grade malignancy, similar to conventional EMC. Our data also suggest that immunohistochemical examination of specific myoepithelial markers is helpful in distinguishing sebaceous EMC from sebaceous carcinoma, which may occasionally be associated with an aggressive clinical course.

Temporal Dynamics of Workplace Acoustic Scenes: Egocentric Analysis and Prediction (2021)

Identification of the acoustic environment from an audio recording, also known as acoustic scene classification, is an active area of research. In this paper, we study dynamically-changing background acoustic scenes from the egocentric perspective of an individual in a workplace. In a novel data collection setup, wearable sensors were deployed on individuals to collect audio signals within a built environment, while Bluetooth-based hubs continuously tracked the individual's location which represents the acoustic scene at a certain time. The data of this paper come from 170 hospital workers gathered continuously during work shifts for a 10 week period. In the first part of our study, we investigate temporal patterns in the egocentric sequence of acoustic scenes encountered by an employee, and the association of those patterns with factors such as job-role and daily routine of the individual. Motivated by evidence of multifaceted effects of ambient sounds on human psychology, we also analyze the association of the temporal dynamics of the perceived acoustic scenes with particular behavioral traits of the individual. Experiments reveal rich temporal patterns in the acoustic scenes experienced by the individuals during their work shifts, and a strong association of those patterns with various constructs related to job-roles and behavior of the employees. In the second part of our study, we employ deep learning models to predict the temporal sequence of acoustic scenes from the egocentric audio signal. We propose a two-stage framework where a recurrent neural network is trained on top of the latent acoustic representations learned by a segment-level neural network. The experimental results show the efficacy of the proposed system in predicting sequence of acoustic scenes, highlighting the existence of underlying temporal patterns in the acoustic scenes experienced in workplace.
Development of an Aircraft Composite Propeller (1979)

&lt;div class="htmlview paragraph"&gt;The current aircraft noise regulations effected the design of propellers where tip speeds were reduced to meet these regulations. Reduced tip speeds were accomplished by reducing propeller rpm and/or propeller diameter. To retain propeller performance, diameters were increased, or the number of blades increased, respectively. These changes effected the propeller weight drastically.&lt;/div&gt; &lt;div class="htmlview paragraph"&gt;A composite propeller blade has been developed that is significantly lighter than a blade fabricated from aluminum.&lt;/div&gt; &lt;div class="htmlview paragraph"&gt;Additional advantages of the composite blade is strength and maintenance characteristics.&lt;/div&gt; &lt;div class="htmlview paragraph"&gt;Considerable testing was accomplished to demonstrate the strength and fatigue characteristics of the blade.&lt;/div&gt;
Corner rounding for increased quality factor of cavity resonators (2006)

In this paper, it is shown, that the quality factor of cavity resonators can be increased through proper arrangement of corner roundings. To overcome numerical uncertainties of the Q-factor calculation, parametric sweeps and polynomial curve fitting are applied. A corresponding analysis is performed for combline resonators and filters by introduction of a base rounding. As a result, the Q-factor is increased by 5%.

Study of the genetic diversity of Korean, Chinese and Japanese landraces of barley (Hordeum vulgare L.) using microsatellites (2011)

Study of the genetic diversity of Korean, Chinese and Japanese landraces of barley ( Hordeum vulgare L.) using microsatellites Barley ( Hordeum vulgare L.) is one of important winter cereals in the world and has been the subject of numerous genetic investigations. Studies of its genetic diversity based on germplasm have a significant impact on crop breeding and conservation of genetic resources. This study was conducted to reveal the genetic diversity in barley landraces from Korean, Chinese and Japanese populations and evaluate the discrimination ability of SSR markers, distributed uniformly throughout the barley genome. Seven SSR primers were used to screen a set of 737 diverse barley landraces from Korea, China and Japan. The observed number of alleles per locus (Na), the effective number of alleles (Ne), and the mean gene diversity (He) were 11.14, 3.6245 and 0.7048, respectively. The number of alleles per locus was highest in Chinese landraces (8.9 alleles), followed by Korean (8.6) and Japanese (6.4). In this regard, HVKASI primer may be useful to distinguish Japanese landraces from others, as this unique allele was only detected at 175 bp in Japanese landraces. The average value of genetic distance was D=0.935. The largest genetic distance (D=1.209) among the three regional (representing each country in general) populations was found between Korean and Japanese populations. Based on the UPGMA dendrogram, four major groups can be distinguished at the similarity value of 0.43. The scatter plot showed overlapping in the central part amongst 3 groups of barley landraces. SSR markers are a powerful tool to examine functional diversity. Rich barley gene pool can be very useful for meeting current and future challenges in barley raising.
Coordination of Overvoltage Protection in Low-Voltage Residential Systems (1978)

This paper was presented as a summary tutorial aimed at the French-speaking Canadian community to solicit their comments on the development of the IEEE Std 587 Guide. The paper has been translated into English by the author to make the English-speaking community aware of that paper, which served at that time as one output for the release of the extensive test results that were reported in the 35-page GE Memo Report – still proprietary at that time – “Lightning protection in residential AC wiring” (see Part 4 of the anthology).
Phosphorus characterization in feces from broiler chicks fed low‐phytate barley diets (2007)

Abstract The inclusion of low phytate grains in poultry diets can reduce the phosphorus (P) content of poultry feces, but their influence on fecal P composition is not well established. To assess this, 100 male broiler chicks (21 days old) were fed dietary treatments based on either a wild‐type barley or one of three low phytate mutant barleys with 59, 62 and 99% reductions in phytate P, compared with the normal barley diet. The birds were housed in raised‐floor battery cages with mesh grate floors above fecal collection trays with five birds per pen and five pens per treatment. The birds were fed for 9 days and feces were collected twice a day during the last 2 days of the experiment. Total P concentrations were 14–24% lower in feces from birds fed low phytate barley diets compared with those fed the normal barley diet. Phosphorus digestibility increased ( P &lt; 0.05) as phytate in the barley diet decreased. Phosphate was the major P fraction in the feces (69–75% extracted P) regardless of the type of barley fed. Phytate constituted only 3–12% of the P in the feces, indicating its hydrolysis in the bird. Overall, these results suggest that feeding low‐phytate barley diets can reduce P concentrations in poultry feces without causing significant changes in P composition.

Essential viral and cellular zinc and iron containing metalloproteins as targets for novel antiviral and anticancer agents: implications for prevention and therapy of viral diseases and cancer. (2001)

In this review the authors summarize the experimental data on the role of a selected group of metalloproteins, particularly viral (v) and cellular (c) zinc finger proteins (ZFP) and iron containing proteins which are involved in cell proliferation, neovascularization, apoptosis, and viral infection. Furthermore, this review summarizes the data embracing the hypothesis that disruption of certain metalloproteins by novel pharmacological agents is a key factor in controlling viral and proliferative diseases. The primary goal of this review is to show the potential therapeutic applications of ZFP disrupting agents, zinc chelators and iron chelators in the control of viral diseases and cancer. It is known that zinc or iron deficiency, resulting from exposure of culture cells to membrane-permeable Zn2+ or Fe(2+)-chelators, can induced apoptosis in virally transformed cells while normal cells remain unaffected under these conditions. Apoptosis is possibly due to simultaneous inactivation of vZFP, cZFP, and/or iron containing proteins, which are essential for maintenance of cellular and viral structure and which are activated in virally transformed cells. New insights concerning apoptosis, viral metalloproteins, and novel antiviral agents will also be reviewed. From the evidence reviewed, one can infer that development of a variety of drugs that control or neutralize vZFP may lead to a new therapeutic approach directed at controlling and preventing a wide spectrum of viral diseases and cancer. Furthermore, the results suggest that these agents may be useful to prevent transmission of viral diseases. Finally, this review not only points out the limits of our understanding of this system, but also directs scientists to opportunities for future research.

Research Directions for Principles of Data Management (Dagstuhl Perspectives Workshop 16151) (2017)

In April 2016, a community of researchers working in the area of Principles of Data Management (PDM) joined in a workshop at the Dagstuhl Castle in Germany. The workshop was organized jointly by the Executive Committee of the ACM Symposium on Principles of Database Systems (PODS) and the Council of the International Conference on Database Theory (ICDT). The mission of this workshop was to identify and explore some of the most important research directions that have high relevance to society and to Computer Science today, and where the PDM community has the potential to make significant contributions. This report describes the family of research directions that the workshop focused on from three perspectives: potential practical relevance, results already obtained, and research questions that appear surmountable in the short and medium term.
Cell Mechanics and Mechanobiology in the Intervertebral Disc (2004)

Information on the mechanisms that govern cell responses to mechanical stimuli in the intervertebral disc are just emerging. Studies must address determination of the factors that control micromechanical stimuli, but also mechanisms by which mechanics may interact with genetic factors to regulate expression and remodeling of extracellular matrix molecules, cytokines and mediators of pain and inflammation in degenerating tissue.
Androgens Are Necessary for the Development of Fructose-Induced Hypertension (2004)

Hyperinsulinemia and insulin resistance are closely associated with hypertension in humans and in animal models. Gender differences have been found in the development of hypertension in fructose-fed rats. The objectives of the present study were, first, to clarify whether androgens are required in the development of hyperinsulinemia, insulin resistance, and hypertension in fructose-fed rats, and second, to determine if cyclooxygenase-1 and cyclooxygenase-2 are also increased in the arteries of these rats. Male rats were gonadectomized or sham-operated and fed a 60% fructose diet beginning at age 7 weeks. Blood pressure was measured by a tail-cuff method, and an oral glucose tolerance test was performed to assess insulin sensitivity after 8 weeks of fructose feeding. Cyclooxygenase-1 and cyclooxygenase-2 mRNA expression was also assessed in the thoracic aortae and mesenteric arteries. Gonadectomy prevented hypertension from developing in the fructose-fed rats, but hyperinsulinemia and insulin resistance developed. There was an increase in cyclooxygenase-2 expression in the thoracic aortae and mesenteric arteries of the fructose-fed sham-operated rats while the expression of cyclooxygenase-1 remained unchanged. Gonadectomy prevented the mRNA overexpression of vascular cyclooxygenase-2 in the fructose-fed rats. These results suggest that the presence of androgens is necessary for the development of fructose-induced hypertension. Androgens apparently act as a link between hyperinsulinemia/insulin resistance and hypertension in fructose-hypertensive rats. Furthermore, an increase in the expression of cyclooxygenase-2 is implicated in the development of hypertension. The mechanisms involved require further study.
The Assessment of Risk of Bias on Randomised Controlled Trials of Oriental Medicine in Korea (2011)

Objectives: To examine the current status of clinical research in oriental medicine, and to assess 'risk of bias'(ROB) of randomized clinical trials(RCTs) in oriental medicine in Korea. Methods: Special committee for EBM, KOMS(Korean Oriental Medicine Society) reviewed 17 journals related to oriental medicine in Korea (from the first issue to May 2010), the Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 2, 2010), and PubMed (1966 to May 2010). Then we selected eligible RCTs in terms of oriental medicine, and assessed 'risk of bias'. Results: We reviewed 12,653 articles from the 17 journals, and 41 articles from CENTRAL and PubMed. After non-clinical articles were excluded, 1,004 articles were left. Among them, the number of eligible studies in terms of oriental medicine was 306. In these eligible studies, 130 were RCTs. Of RCTs, 69 were on acupuncture, 25 on herbal medicine. The proportion of 'unclear' is high in the criteria of 'Allocation concealment', 'Blinding of participants and personnel', 'Blinding of outcome assessment' and 'Other bias'. On the other hand, 'low' has high in the criteria of 'Incomplete outcome data' and 'Selective reporting'. Conclusions: Risk of bias on oriental medicine is unclear in terms of 'allocation concealment' and 'blinding'. For high-quality research in oriental medicine, further research should be needed on randomization and blinding in the RCTs.
Realistic wave-optics simulation of X-ray phase-contrast imaging at a human scale (2015)

X-ray phase-contrast imaging (XPCI) can dramatically improve soft tissue contrast in X-ray medical imaging. Despite worldwide efforts to develop novel XPCI systems, a numerical framework to rigorously predict the performance of a clinical XPCI system at a human scale is not yet available. We have developed such a tool by combining a numerical anthropomorphic phantom defined with non-uniform rational B-splines (NURBS) and a wave optics-based simulator that can accurately capture the phase-contrast signal from a human-scaled numerical phantom. Using a synchrotron-based, high-performance XPCI system, we provide qualitative comparison between simulated and experimental images. Our tool can be used to simulate the performance of XPCI on various disease entities and compare proposed XPCI systems in an unbiased manner.
Performance Analysis of Resonantly Driven Piezoelectric Sensors Operating in Amplitude Mode and Phase Mode (2023)

Piezoelectric layers coupled to micromechanical resonators serve as the basis for sensors to detect a variety of different physical quantities. In contrast to passive sensors, actively operated sensors exploit a detuning of the resonance frequency caused by the signal to be measured. To detect the time-varying resonance frequency, the piezoelectric resonator is resonantly excited by a voltage, with this signal being modulated in both amplitude and phase by the signal to be measured. At the same time, the sensor signal is impaired by amplitude noise and phase noise caused by sensor-intrinsic noise sources that limit the reachable detectivities. This leads to the question of the optimum excitation frequency and the optimum readout type for such sensors. In this article, based on the fundamental properties of micromechanical resonators, a detailed analysis of the performance of piezoelectric resonators in amplitude mode and phase mode is presented. In particular, the sensitivities, the noise behavior, and the resulting limits of detection (LOD) are considered and analytical expressions are derived. For the first time, not only the influence of a static measurand is analyzed, but also the dynamic operation, i.e., physical quantities to be detected that quickly change over time. Accordingly, frequency-dependent limits of detection can be derived in the form of amplitude spectral densities. It is shown that the low-frequency LOD in phase mode is always about 6 dB better than the LOD in amplitude mode. In addition, the bandwidth, in terms of detectivity, is generally significantly larger in phase mode and never worse compared with the amplitude mode.
