Development of an all-metal vacuum bellows following twist motion (1999)

A novel all-metal vacuum bellows that can follow a twist motion around the axis was designed and developed. The bellows, called here a “twist bellows,” consists of two normal bellows sections and one special bellows section whose corrugation is oblique to the axis. A trial model with a total length of 400 mm and an inner diameter of 100 mm is able to absorb the twist up to about ±22° (44° total) within a twist torque of about 12 N m (120 kg cm) while keeping the total length constant. The twist bellows can also follow the usual bending, shifting, expanding and contracting motion easily like a conventional bellows. The twist bellows allows an unobstructed direct view along the axis and is especially useful for vacuum system of accelerators or synchrotron light beam lines.
Increase of bcr-abl chimeric mRNA expression in tumor cells of patients with chronic myeloid leukemia precedes disease progression (1995)

The translocation t(9;22) in chronic myeloid leukemia (CML) generates a bcr-abl fusion gene that codes for an aberrant chimeric mRNA. Cell lines established from CML patients in blast crisis show higher expression of this aberrant bcr-abl transcript than cells from patients in chronic phase of the disease. This observation provided the stimulus to investigate whether increased expression of the aberrant bcr-abl fusion transcript is critical to the progression of CML from chronic phase to blast crisis. We have monitored the bcr-abl mRNA expression in 25 patients by serial quantitative polymerase chain reaction analyses during a follow-up period of 12 to 156 months after diagnosis, with a median observation time of 28 months. In all patients who have shown disease progression to accelerated phase (n = 4) or blast crisis (n = 7), an increase in bcr-abl mRNA expression was detected up to 16 months before laboratory or clinical parameters showed phenotypic transformation of the malignant clone. To investigate whether the elevated levels of bcr-abl mRNA reflected an increase in the proportion of leukemic cells in the samples analyzed or primarily enhanced transcriptional activity of the bcr-abl fusion gene, we performed quantitative analyses of the bcr-abl gene at the DNA level and of the Ph chromosome at the cytogenetic level and compared these data with steady-state bcr-abl mRNA levels. We show that increased levels of the bcr-abl transcript did not reflect increased proportions of leukemic cells but elevated steady-state levels of the chimeric mRNA in the malignant cells before disease progression. Therefore, our data strongly suggest that an increase of the chimeric mRNA expression in the leukemic cells precedes the phenotypic transformation of the malignant clone.
Concepts of battery charger control using polarization voltage (1996)

A new concept is proposed for employing polarization voltage as the control variable for maintaining a proper state of charge on all cells in a battery string. The charger would take advantage of a patented technology for measuring polarization voltage, and would permit each cell to be charged only to the point at which the cell requires a charge. It is shown that, since all cells differ at least slightly in geometric, chemical, and electrical aspects, it is more appropriate to allow the cell`s individual properties to dictate its required charge level. The appearance of a polarization voltage is taken to be the point at which the cell is properly charged. Only lead acid batteries are addressed, though the technique may also apply to other types of cells. The charger concept is described, along with its benefits, applications, and required future research.
Egg White Protein Separation Development: Effect of Buffers and Untreated Fused Silica vs. Neutral Covalently Bonded Columns (1993)

Abstract A method for the separation of three egg white proteins, lysozyme, conalbumin, and ovalbumin, was developed based on desired criteria of reproducible baseline separation of all components in under 25 minutes. Fixed parameters were 50cm effective column length, 200 volts/cm field strength. Sodium phosphate, sodium borate, and phosphate/borate combination buffers were compared in different ionic strengths. The performance of bonded phase columns, CEIect(tm)-P1 and CEIect-H (patent pending) were compared to that of untreated fused silica. The optimal separation was obtained using 100mM phosphate / 60 mM borate buffer, pH 8.0 on the hydrophilic CEIect-P1 bonded phase column.
Design of a Neutral Macrocyclic Ionophore: Synthesis and Binding Properties for Nitrate and Bromide Anions (2002)

A macrocyclic neutral ionophore 8 (X = O) capable of binding weakly coordinating anions such as nitrate and bromide in DMSO solution has been designed by a stepwise, deductive approach. The optimum geometrical arrangement of the hydrogen bond donor sites in the target ionophore was determined by DFT calculations. From these data, a suitable macrocyclic molecular framework was constructed. The 24-membered macrocyclic ionophore was synthesized by standard macrocyclization methods. NMR titrations revealed molecular complexes with defined 1:1 stoichiometries in DMSO for 8 (X = O) with nitrate, hydrogensulfate, acetate, cyanide, iodide, and bromide ions, while dihydrogenphosphate, sulfate, and chloride ions yielded aggregates of higher stoichiometry. The nitrate binding constants of 8 (X = O) are substantial for a neutral ionophore with defined binding sites in pure DMSO solution. Bromide ions, which have a similar ion radius, are bound with an even higher affinity. Chloride is obviously too small, and iodine too large, to form 1:1 complexes. The binding motif of 8 (X = O) was compared with related molecules of similar structure, such as 8 (X = S) and 19. As predicted from calculations, the small structural variations give rise to a complete loss of nitrate and bromide ion binding ability in DMSO. This sensitivity to geometrical changes and the affinity of 8 (X = O) to nitrate and bromide ions, which are poor hydrogen bond acceptors, confirm the predicted complementarity of ionophore binding site and anion geometry. According to DFT and MD calculations the higher affinity of 8 (X = O) to bromide than to nitrate is mainly due to the greater flexibility of the bromide complex and thus to its higher entropy.

Measuring the Ecological Footprint of a Himalayan Tourist Center (2002)

Finding ways to assess and measure the impact of tourism and its associated development on sustainability is critical to developing long-term sustainability plans for regions such as the Indian Himalayas. Among the methods proposed is ecological footprint (EF) analysis or appropriated carrying capacity analysis. EF analysis estimates the area of productive land and water ecosystems required to produce the resources that a population consumes and to assimilate the wastes that the population produces in supporting itself. This study used EF analysis to quantify the sustainability of Manali, a rapidly growing tourist center in Kullu District, Himachal Pradesh, India. It considered the changes in the size of Manali's footprint since the advent of mass tourism in the early 1980s, the direct impact that tourists are having on the size of the footprint, and the challenges of applying this analysis in a developing world context. Data regarding land use, goods and services, and population were collected through local interviews and available data. The results indicate that between 1971 and 1995, the overall EF of Manali town grew from 2102 to 9665 ha, an increase of over 450%; the EF of Manali is now 25 times greater than its size. This indicates that Manali is increasingly relying on outside ecosystems for its sustenance. The article highlights areas of focus for future sustainability planning, including waste management, decreasing fossil fuel dependence, ecofriendly tourism, and creating greater environmental awareness, particularly among tourists.
In-fiber spectrometer using tilted fiber gratings (2003)

We demonstrate a compact in-fiber low-resolution spectrometer. Wavelength resolution of 7 nm was achieved using the core radiation-mode coupling of a tilted grating in an optical fiber with a photosensitive cladding. We applied the device to measure the powers of a multiwavelength Raman pump source.
Interconnection of solar powered mini-grids - a case study for Kythnos Island (2022)

The introduction of a substantial penetration from renewable energy sources in the power mix of the Greek islands grids is of great importance. This fact is justified because the island grids are autonomous and are mainly fed by diesel generators, that increase dramatically the energy production cost. Although the wind and solar potential in these areas is excellent, the strong seasonal demand fluctuations as well as the technical minimum restrictions of the thermal stations, pose a barrier. The implementation of a hybrid system with battery storage and an intelligent management system in Kythnos island, are considered to be an effective solution to this problem. The scope of this paper is to examine some grid impact issues for two case studies involving the increase of renewable energy source penetration in the grid of this island.
Bound simian virus 40 translocates to caveolin-enriched membrane domains, and its entry is inhibited by drugs that selectively disrupt caveolae. (1996)

Simian virus 40 (SV40) entry leading to infection occurred only after the virus was at the cell surface for 1.5 to 2 h. SV40 infectious entry was not sensitive to cytosol acidification, a treatment that blocks endocytosis via clathrin-coated vesicles. Instead, SV40 infectious entry was blocked by treating cells with the phorbol ester PMA or nystatin, which selectively disrupts caveolae. In control experiments, transferrin internalization was sensitive to cytosol acidification but was not sensitive to PMA or nystatin. Also, absorbed transferrin entered cells within minutes. Finally, bound SV40 translocated to caveolin-enriched membrane complexes isolated by a Triton X-100 insolubility protocol. Treatment with nystatin did not impair SV40 binding but did block the partitioning of virus into the caveolin-enriched complexes.
Cell cycle-dependent regulation of RNA polymerase II basal transcription activity (1995)

Regulation of transcription by RNA polymerase II (pol II) in eukaryotic cells requires both basal and regulatory transcription factors. In this report we have investigated in vitro pol II basal transcription activity during the cell cycle by using nuclear extracts from synchronized HeLa cells. It is shown that pol II basal transcription activity is low in the S and G2 phases and high in early G1 phase and TFIID is the rate limiting component of pol II basal transcription activity during the cell cycle. Further analyses reveal that TFIID exists as a less active form in the S and G2 phases and nuclear extracts from S and G2 phase cells contain a heat-sensitive repressor(s) of TATA box binding protein (TBP). These results suggest that pol II basal transcription activity is regulated by a qualitative change in the TFIID complex, which could involve repression of TBP, during the cell cycle.
Tissue‐specific alternative splicing of mouse brain type ryanodine receptor/calcium release channel mRNA (1996)

We detected alternative splicing of the mouse brain type ryanodine receptor (RyR3) mRNA. The splicing variant was located in the transmembrane segment. The non-splicing type (RyR3-II) included a stretch of 341 bp, and that of the 13th codon was stop codon TAA. Reverse transcription-polymerase chain reaction (RT-PCR) analysis shows that RyR3-II mRNA was expressed in various peripheral tissues and brain at all developmental stages. However, interestingly, the splicing type (RyR3-I) mRNA was detected only in the cerebrum. These findings suggest that the splicing variants RyR3-I and RyR3-II may generate functional differences of RyR3 in a tissue-specific manner.
A Comparison of High Precision FO Extraction Algorithms for Sustained Vowels (1999)

Perturbation analysis of sustained vowel waveforms is used routinely in the clinical evaluation of pathological voices and in monitoring patient progress during treatment. Accurate estimation of voice fundamental frequency (F0) is essential for accurate perturbation analysis. Several algorithms have been proposed for fundamental frequency extraction. To be appropriate for clinical use, a key consideration is that an F0 extraction algorithm be robust to such extraneous factors as the presence of noise and modulations in voice frequency and amplitude that are commonly associated with the voice pathologies under study. This work examines the performance of seven F0 algorithms, based on the average magnitude difference function (AMDF), the input autocorrelation function (AC), the autocorrelation function of the center-clipped signal (ACC), the autocorrelation function of the inverse filtered signal (IFAC), the signal cepstrum (CEP), the Harmonic Product Spectrum (HPS) of the signal, and the waveform matching function (WM) respectively. These algorithms were evaluated using sustained vowel samples collected from normal and pathological subjects. The effect of background noise and of frequency and amplitude modulations on these algorithms was also investigated, using synthetic vowel waveforms.
Bloqueio divisional ântero-medial intermitente em paciente com insuficiência coronária (1997)

We report the case of a 69 year-old male who developed congestive heart failure functional class IV (NYHA). The admission electrocardiogram (EKG) revealed sinus rhythm, PR interval of 240ms, QRS interval of 110ms, the QRS vector of 0o, Q waves from V 1 to V 6 , tall R waves from V 1 to V 4 that decreased to V 5 and V 6 . The vectocardiogram had anteriorization of the electral forces of QRS, with vector half area in the horizontal plane at +60o. After two years the patient had a myocardial infarction, the EKG at the admision had the same pattern and after two days developed important changes: enlargement of QRS interval with length of 160ms, QRS vector of +100o, R waves at D 2 , D 3 e AVF that increase from D 2 to D 3 , QS at D 1 , AVL, AVR and V 1 , rS at V 2 and V 3 , R wave is notched and thicked at V 5 and V 6 , that return to the initial pattern after one day. The patient progressed to death in the eighth day after infarction. This case reported a intermitent pattern of EKG that is an uncontestable proof to the existence of the left middle fascicular block. Homem de 69 anos, apresentando insuficiencia cardiaca congestiva, classe funcional IV (NYHA). Ao eletrocardiograma (ECG) apresentava ritmo sinusal, intervalo PR de 240ms, duracao de QRS 110ms, eixo de QRS em 0o, ondas Q de V 1 a V 6 , ondas R amplas de V 1 a V 4 que decresciam em direcao a V 5 e V 6 . Ao vetorcardiograma apresentava anteriorizacao das forcas de QRS, com vetor meia area no plano horizontal em +60o. Apos dois anos, reinternou com episodio de infarto agudo do miocardio (IAM), mas o ECG de entrada apresentava padrao semelhante ao da 1a internacao. No 3o dia pos-infarto, o ECG evolui com alteracoes importantes: alargamento do QRS com duracao de 160ms, eixo de QRS de +100o, presenca de ondas R em D 2 , D 3 e AVF que cresciam de D 2 para D 3 , QS em D 1 , AVL, AVR e V 1 , rS em V 2 e V 3 , onda R espessada e entalhada em V 5 e V 6 , que retornou ao padrao apos um dia. No 8o dia apos o infarto, o paciente evolui para obito. Neste caso a intermitencia do padrao do ECG e uma prova inequivoca para confirmar a existencia do bloqueio divisional ântero-medial.

Parallel instance discrete-event simulation using a vector uniprocessor (1991)

The authors examine the possibility of running simulations in parallel on a vector processor. In such a system each instance of execution runs identical code but with a different input data set. The main problem addressed is the choice of block selection policy, that is, the choice of which indivisible block of code to execute next. The authors investigate four block selection policies by simulating the execution of such a system. A stochastic flow-graph representation was chosen to model the execution of a simulation. A two-level block selection policy was found to have the best potential speedup of the four block selection policies. The speedup levels achieved were not large, and decreased when there are a large number of unique event types (and therefore handlers) in the simulated system. >

Flow graph reducibility (1972)

The structure of programs can often be described by a technique called “interval analysis” on their flow graphs. Here, we characterize the set of flow graphs that can be analyzed in this way in terms of two very simple transformation on graphs. We then give a necessary and sufficient condition for analyzability and apply it to “goto-less programs,” showing that they all meet the criterion.
A Method Using Optical Contactless Displacement Sensors to Measure Vibration Stress of Small-Bore Piping (2013)

In nuclear power plants, vibration stress of piping is frequently evaluated to prevent fatigue failure. A simple and fast measurement method is attractive to evaluate many piping systems efficiently. In this study, a method to measure the vibration stress using optical contactless displacement sensors was proposed, the prototype instrument was developed, and the instrument practicality for the method was verified. In the proposed method, light emitting diodes (LEDs) were used as measurement sensors and the vibration stress was estimated by measuring the deformation geometry of the piping caused by oscillation, which was measured as the piping curvature radius. The method provided fast and simple vibration estimates for small-bore piping. Its verification and practicality were confirmed by vibration tests using a test pipe and mock-up piping. The stress measured by both the proposed method and an accurate conventional method using strain gauges were in agreement, and it was concluded that the proposed method could be used for actual plant piping systems.
Absolute scale in structure from motion from a single vehicle mounted camera by exploiting nonholonomic constraints (2009)

In structure-from-motion with a single camera it is well known that the scene can be only recovered up to a scale. In order to compute the absolute scale, one needs to know the baseline of the camera motion or the dimension of at least one element in the scene. In this paper, we show that there exists a class of structure-from-motion problems where it is possible to compute the absolute scale completely automatically without using this knowledge, that is, when the camera is mounted on wheeled vehicles (e.g. cars, bikes, or mobile robots). The construction of these vehicles puts interesting constraints on the camera motion, which are known as “nonholonomic constraints”. The interesting case is when the camera has an offset to the vehicle's center of motion. We show that by just knowing this offset, the absolute scale can be computed with a good accuracy when the vehicle turns. We give a mathematical derivation and provide experimental results on both simulated and real data over a large image dataset collected during a 3 Km path. To our knowledge this is the first time nonholonomic constraints of wheeled vehicles are used to estimate the absolute scale. We believe that the proposed method can be useful in those research areas involving visual odometry and mapping with vehicle mounted cameras.
The DIVA model: A neural theory of speech acquisition and production (2010)

The DIVA model of speech production provides a computationally and neuroanatomically explicit account of the network of brain regions involved in speech acquisition and production. An overview of the model is provided along with descriptions of the computations performed in the different brain regions represented in the model. The latest version of the model, which contains a new right-lateralized <i>feedback control map</i> in ventral premotor cortex, will be described, and experimental results that motivated this new model component will be discussed. Application of the model to the study and treatment of communication disorders will also be briefly described.
Nucleotide sequence of alkalophilic Bacillus oligo-1,6-glucosidase gene and the properties of the gene product by Escherichia coli HB 101. (1990)

The nucleotide sequence of alkalophilic Bacillus oligo-1, 6-glucosidase gene was determined . The coding sequence on a 3.1 kb DNA fragment in pMC21 showed an open reading frame of 1527 by encoding 509 amino acids. The amino acid sequence from position 2 to 11 corresponds exactly to the NH2-terminal sequence of the purified enzyme protein from strain F5. The molecular weight (60, 142) of the protein derived from 1524 by open reading frame coincided with the molecular weight (60, 000) of the parent strain. On the other hand, the molecular weight of purified oligo-1, 6-glucosidase produced by E. coli HB101 carrying plasmid pMC21 showed 65, 000 by SDS-PAGE. The enzymatic properties, i. e., pH and temperature optima, pH and thermal stabilities, and substrate specificities, were almost the same as those obtained from an alkalophilic Bacillus sp. (strain F5).
A Note on the Ate Pairing. (2007)

Abstract. The Ate pairing has been suggested since it can be computed efficiently on ordinary elliptic curves with small values of the traces of Frobenius t. However, not all pairing-friendly elliptic curves have this property. In this paper, we generalize the Ate pairing and find a series of variations of the Ate pairing. We show that the shortest Miller loop of the variations of the Ate pairing can possibly be as small as r 1/ϕ(k) on more pairing-friendly curves generated by the method of complex multi-plications, and hence speed up the pairing computation significantly.
