Electron accelerator's production of technetium-99m for nuclear medicine (2002)

At present Technetium-99m provides up to 90% isotopic products used in nuclear medicine. The generator Molybdenum-99 is mainly produced in fission reactors. Most of reactors used for this production are approaching the end of their working life. One suggests to use photonuclear reactions in /sup 100/Mo under influence of bremsstrahlung of a powerful electron accelerator as an alternative method of /sup 99m/Tc production. Report contents both an analysis, of some technical, economical and ecological aspects of method and the results of experimental production of /sup 99m/Tc with KIPT electron linac, as well as results of medical test of produced radiopharmaceuticals.
Comparing Once- versus Twice-Weekly Yoga Classes for Chronic Low Back Pain in Predominantly Low Income Minorities: A Randomized Dosing Trial (2013)

Background. Previous studies have demonstrated that once-weekly yoga classes are effective for chronic low back pain (cLBP) in white adults with high socioeconomic status. The comparative effectiveness of twice-weekly classes and generalizability to racially diverse low income populations are unknown. Methods. We conducted a 12-week randomized, parallel-group, dosing trial for 95 adults recruited from an urban safety-net hospital and five community health centers comparing once-weekly (n = 49) versus twice-weekly (n = 46) standardized yoga classes supplemented by home practice. Primary outcomes were change from baseline to 12 weeks in pain (11-point scale) and back-related function (23-point modified Roland-Morris Disability Questionnaire). Results. 82% of participants were nonwhite; 77% had annual household incomes <$40,000. The sample's baseline mean pain intensity [6.9 (SD 1.6)] and function [13.7 (SD 5.0)] reflected moderate to severe back pain and impairment. Pain and back-related function improved within both groups (P < 0.001). However, there were no differences between once-weekly and twice-weekly groups for pain reduction [-2.1 (95% CI -2.9, -1.3) versus -2.4 (95% CI -3.1, -1.8), P = 0.62] or back-related function [-5.1 (95% CI -7.0, -3.2) versus -4.9 (95% CI -6.5, -3.3), P = 0.83]. Conclusions. Twelve weeks of once-weekly or twice-weekly yoga classes were similarly effective for predominantly low income minority adults with moderate to severe chronic low back pain. This trial is registered with ClinicalTrials.gov NCT01761617.
Intrinsic Fabry-Perot interferometric fiber sensor based on ultra-short Bragg gratings for quasi-distributed strain and temperature measurements (2006)

The health monitoring of smart structures in civil engineering is becoming more and more important as in-situ structural monitoring would greatly reduce structure life-cycle costs and improve reliability. The distributed strain and temperature sensing is highly desired in large structures where strain and temperature at over thousand points need to be measured simultaneously. It is difficult to carry out this task using conventional electrical strain sensors. Fiber optic sensors provide an excellent opportunity to fulfill this need due to their capability to multiplex many sensors along a single fiber cable. Numerous research studies have been conducted in past decades to increase the number of sensors to be multiplexed in a distributed sensor network. This dissertation presents detailed research work on the analysis, design, fabrication, testing, and evaluation of an intrinsic Fabry-Perot fiber optic sensor for quasi-distributed strain and temperature measurements. The sensor is based on two ultra-short and broadband reflection fiber Bragg gratings. One distinct feature of this sensor is its ultra low optical insertion loss, which allows a significant increase in the sensor multiplexing capability.

Distance enhancing codes for E/sup 2/PRML: performance comparison using spinstand data (1997)

Two new RLL encoding schemes for the E/sup 2/PR4 recording channel are analyzed experimentally. These codes, employing a d=0 run length constraint, simplify the detector complexity while achieving a higher code rate than the traditional (1,7) recording code. They also maintain the same minimum squared distance, d/sup 2/=10, as the (1,7) code. Using spin-stand data from an MR head, the new codes show an order of magnitude improvement in BER over (1,7) coded data in the range of UBD=2.2 to 2.6.
Towards a Notion of Transaction in Graph Rewriting (2008)

We define transactional graph transformation systems (t-gtss), a mild extension of the ordinary framework for the double-pushout approach to graph transformation, which allows to model transactional activities. Generalising the work on zero-safe nets, the new graphical formalism is based on a typing discipline which induces a distinction between stable and unstable items. A transaction is then a suitably defined minimal computation which starts and ends in stable states. After providing the basics of t-gtss, we illustrate the expected results, needed to bring the theory to full maturity, and some possible future developments.
Selective suppression of insulin-induced proliferation of cultured human hepatoma cells by somatostatin. (1987)

The effects of somatostatin (SRIF), insulin, and triiodothyronine (T3) on the growth of human hepatoma cells were investigated on the well-differentiated human hepatoma cell line Hep3B. Results showed that both insulin and T3 can stimulate cell growth of serum starved Hep3B cells at physiological concentrations. SRIF alone showed little growth-promoting activity. When added concurrently with insulin, however, SRIF suppressed the insulin-induced cell proliferation in a dose-dependent manner. On the other hand, SRIF had no inhibitory effect on T3-induced cell proliferation. SRIF is labile in the medium, with a half-life of about 2 h during culture incubation. SRIF did not disturb the insulin binding to its surface receptors nor inhibit the insulin-dependent receptor kinase activity of Hep3B cells in vitro. These results suggest that postreceptor regulation may be involved. The selective suppression by SRIF of insulin-induced cell growth provides an unique approach to the study of insulin actions on proliferation of human hepatoma cells.
Better proposal distributions: object tracking using unscented particle filter (2005)

Tracking objects involves the modeling of non-linear non-Gaussian systems. On one hand, variants of Kalman filters are limited by their Gaussian assumptions. On the other hand, conventional particle filter, e.g., CONDENSATION, uses transition prior as the proposal distribution. The transition prior does not take into account current observation data, and many particles can therefore be wasted in low likelihood area. To overcome these difficulties, unscented particle filter (UPF) has recently been proposed in the field of filtering theory. In this paper, we introduce the UPF framework into audio and visual tracking. The UPF uses the unscented Kalman filter to generate sophisticated proposal distributions that seamlessly integrate the current observation, thus greatly improving the tracking performance. To evaluate the efficacy of the UPF framework, we apply it in two real-world tracking applications. One is the audio-based speaker localization, and the other is the vision-based human tracking. The experimental results are compared against those of the widely used CONDENSATION approach and have demonstrated superior tracking performance.
Dehydroepiandrosterone for women in the peri- or postmenopausal phase (2015)

There is no evidence that DHEA improves quality of life but there is some evidence that it is associated with androgenic side effects. There is uncertainty whether DHEA decreases menopausal symptoms, but DHEA may slightly improve sexual function compared with placebo.
[The role of seminal vesicles in male reproduction and sexual function]. (2007)

The present review is intended to give an outlook on the relationship between male reproduction and seminal vesicles, which are an important subsidiary gonad of males and play a key role in male fertility process. Seminal vesicle secretion is important for semen coagulation and may promote sperm motility, increase stability of sperm chromatin, and suppress the immune activity in the female reproductive tract. Furthermore, the sexual function of males is closely related to the swelling degree of seminal vesicles. The abnormal function of seminal vesicles may give rise to sexual dysfunction and infertility of males.
Untersuchung 5 (1978)

In diesem Versuch wird der Einfluß der Dimension Aktivität-Passivität -wie oben beschrieben — auf die Geschlechtsidentifikation, sowie auf Exploration überprüft. Aufgrund der Schwierigkeiten, Methoden der Aktivitätserfassung aus einer Theorie zu deduzieren, wird hier ein deskriptiver Ansatz verfolgt. Ausgehend von Überlegungen, in welchen Bereichen sich Aktivität überhaupt äußern kann, kamen wir zur folgenden Aufstellung: einmal interessierte hier ein Gesamtmaß der Aktivität, wie es etwa überdauerndes (habituelles) Maß der Emotionalität von Janke und Debus (1970) in der Eigenschaftswörterliste (EWL) operationalisiert wurde; zum anderen kam hier in Frage Aktivität im Leistungsbereich (meßbar als Leistungsmotivation), geistige Aktivität und soziale Aktivität (meßbar als Extraversion). Wir formulieren die folgenden Hypothesen:

Fast Approach for Battery Impedance Identification Using Pseudo-Random Sequence Signals (2019)

Online measurements of the battery impedance provide valuable information on the battery state-of-charge and state-of-health, which can be utilized for improving the safety and the performance of the associated system. The electrochemical-impedance spectroscopy (EIS) is widely used for battery impedance measurements, but it is not the most applicable solution for online measurements due to its slowness and complexity. These drawbacks can be improved using broadband signals, such as pseudorandom sequences (PRS), which are fast and easily implementable. However, the nonlinear behavior of batteries have a significant effect on the impedance measurements and the selection of the PRS signal. Majority of the PRS signals are applicable for measurements of linear systems, but also signals for nonlinear system identification do exist. Moreover, the reduced accuracy and signal-to-noise ratio of the PRS signals compared to the EIS make the filtering of the results as well as the amplitude design important aspects. This paper demonstrates the use of two PRS signals, the pseudorandom binary sequence (PRBS), and a ternary sequence with better toleration to battery nonlinear effects, with comprehensive amplitude and filtering design for battery impedance measurements. It is shown that the ternary sequence provides accurate measurements and the effects of nonlinear dynamics of the battery impedance are reduced with respect to the PRBS measurements. The results are referenced and validated to practical EIS measurements in various operating conditions for lithium-iron-phosphate (LiFePO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</sub> ) cell.
High-Efficiency Nondoped Deep-Blue-Emitting Organic Electroluminescent Device (2010)

A new blue emitter, 9,9-bis-(3- (9-phenyl-carbazoyl))-2,7-dipyrenylfluorene (DCDPF), has been synthesized and characterized. Organic light-emitting devices (OLEDs) using DCDPF as a nondoped emitter exhibits deep-blue emission with a peak at 458 nm and CIE coordinates of (0.15, 0.15). The maximum efficiency of the device is 4.4 cd/A (3.1 lm/W). The results suggest that the introduction of carbazole units at the 9-position of fluorene provides an effective way to suppress molecular aggregation which would cause red shift in emission.
Synthesis of novel side‐chain triphenylamine polymers with azobenzene moieties via RAFT polymerization and investigation on their photoelectric properties (2012)

Abstract Two novel and well‐defined polymers, poly[6‐(5‐(diphenylamino)‐2‐((4‐methoxyphenyl)diazenyl)phenoxy)hexyl methacrylate] (PDMMA) and poly[6‐(4‐((3‐ethynylphenyl)diazenyl) phenoxy)hexyl methacrylate] (PDPMMA), which bear triphenylamine (TPA) incorporated to azobenzene either directly (PDMMA) or with an interval (PDPMMA) as pendant groups were successfully prepared via reversible addition‐fragmentation chain transfer polymerization technique. The electrochemical behaviors of PDPMMA and PDMMA were investigated by cyclic voltammograms (CV) measurement. The hole mobilities of the polymer films were determined by fitting the J ‐V (current‐voltage) curve into the space‐charge‐limited current method. The influence of photoisomerization of the azobenzene moiety on the behaviors of fluorescence emission, CV and hole mobilities of these two polymers were studied. The fluorescent emission intensities of these two polymers in CH 2 Cl 2 were increased by about 100 times after UV irradiation. The oxidation peak currents ( I OX ) of the PDMMA and PDPMMA in CH 2 Cl 2 were increased after UV irradiation. The photoisomerization of the azobenzene moiety in PDMMA had significant effect on the electrochemical behavior, compared with that in PDPMMA. The changes of the hole mobility before and after UV irradiation were very small for both polymers. The HOMO energies ( E HOMO , HOMO: the highest occupied molecular orbital) of side chain moieties of TPA incorporated with cis ‐isomer and trans ‐isomer of azobenzene in PDMMA and PDPMMA were obtained by theoretical calculation, which are basically consistent with the experimental results. © 2012 Wiley Periodicals, Inc.

Present an architecture for batch process management with particular emphasis on the simulation tools contained in the environment. Within the architecture are a suite of high-level tools that interface with a user to obtain a high level of batch processing flexibility. These high-level tools are being developed in a modular fashion. Two simulation assistants have been proposed for a complete batch process management architecture. These include a batch sequencing simulation assistant and a control specification simulation assistant. It is felt that these tools will significantly increase the batch process management life-cycle time and increase process plant flexibility. >
Isomerization and Peroxidizing Phytotoxicity of Thiadiazolidine-thione Compounds (1995)

Eight 5-arylimino-3,4-tetramethylene-1,3,4-thiadiazolidine-2-thiones and eight 4-aryl-1,2- tetramethylene-1,2,4-triazolidine-3,5-dithiones were synthesized and their phytotoxic activities were investigated using sawa millet (Echinochloa utilis), green microalgae (Scenedesmus acutus) and protoporphyrinogen-IX oxidase isolated from etiolated corn (Zea mays) seedlings. 5-Arylimino-3,4-tetramethylene-1,3,4-thiadiazolidine-2-thiones showed strong phytotoxic activities and the same herbicidal mode of action as known for peroxidizing herbicides. 5-Arylimino-3,4-tetramethylene-1,3,4-thiadiazolidine-2-thiones were not or very little converted into 4-aryl-1,2-tetram ethylene-1,2,4-triazolidine-3,5-dithiones either with E. utilis seedlings present for 7 days, with S. acutus cells, or using glutathione 5-transferase (GST) and glutathione (GSH). The phytotoxic activities of 4-aryl-1,2-tetram ethylene-1,2,4-triazolidine- 3,5-dithiones were stronger than those of 5-arylimino-3,4-tetram ethylene-1,3,4-thiadiazolidine- 2-thiones [cf. Sato, Y., et al., Z. Naturforsch. 49c, 49-56 (1994)].
Theory of Thermal Hologram Fixing and Application to LiNbO3:Cu (1987)

Volume phase holograms in an electrooptic crystal like LiNbO3 must be fixed so that they are not destroyed upon reading. By heating up the crystal mobilized ions may partially compensate the electronic space charge field, and a subsequent development procedure fixes the hologram. A general theory of this thermal fixing process is developed and applied to LiNbO3:Cu. Charge transport by the photovoltaic effect, by drift in a space charge field and by diffusion is taken into account. It is unlikely that mobile protons alone are responsible for the fixing effect. Volumenphasenhologramme in einem elektrooptischen Kristall wie LiNbO3 müssen fixiert werden, so daß sie nach dem Lesen nicht zerstört werden. Die durch Aufheizen der Kristalle mobilisierten Ionen können partiell das elektronische Raumladungsfeld kompensieren und ein darauffolgendes Entwicklungsverfahren fixiert das Hologramm. Eine allgemeine Theorie dieses thermischen Fixierungsprozesses wird aufgestellt und auf LiNbO3:Cu angewendet. Ladungstransport durch den photovoltaischen Effekt, durch Drift in einem Raumladungsfeld und durch Diffusion werden berücksichtigt. Es ist unwahrscheinlich, daß bewegliche Protonen allein für den Fixierungseffekt verantwortlich sind.
Balancing the Trade-Offs between Query Delay and Data Availability in MANETs (2011)

In mobile ad hoc networks (MANETs), nodes move freely and link/node failures are common, which leads to frequent network partitions. When a network partition occurs, mobile nodes in one partition are not able to access data hosted by nodes in other partitions, and hence significantly degrade the performance of data access. To deal with this problem, we apply data replication techniques. Existing data replication solutions in both wired or wireless networks aim at either reducing the query delay or improving the data availability, but not both. As both metrics are important for mobile nodes, we propose schemes to balance the trade-offs between data availability and query delay under different system settings and requirements. Extensive simulation results show that the proposed schemes can achieve a balance between these two metrics and provide satisfying system performance.
Phenolic Compound Contents and Antioxidative Effects on Dutch Coffee by Extraction Time (2013)

Objectives: This study was conducted to investigate change of the antioxidative activity and phenolic compounds contents in Dutch coffee by different extraction times. Methods: Chemical characteristics and DPPH radical scavenging activity in dutch coffee with different extraction times were analyzed. Results: Cold water dissolved more coffee ingredients in the early extacts. Crude protein, crude lipid, soluble solids, crude ash in 0-3 hour extracts were 2 times more than in the latter extracts. However, total phenolic compounds were not changed durng the extractoin time of 0 ∼6 hous. The latter extracts had high DPPH radical scavenging activity. Conclusion: Dutch coffee extracts had enough antioxidative and bioactive ingredients.
A 20Mbps 5.8mw QPSK transmitter based on injection locking and Class-E PA for wireless biomedical applications (2017)

This paper presents a power-efficient, high data rate QPSK transmitter for wireless biomedical applications at the frequency of 430MHz. The transmitter architecture is based on a sub-harmonic injection-locked voltage-controlled oscillator (VCO) and the phase modulation is realized by directly modifying the VCO self-resonant frequency. A single-ended Class-E power amplifier (PA) is adopted in the transmitter with an efficiency of 46% (including pre-driver). Implemented in 0.18μm CMOS technology, the proposed transmitter consumes 5.8mw with 20Mbps data rate and 0.11dBm output power.
Morphology of pyramidal neurones in monkey motor cortex and the synaptic actions of their intracortical axon collaterals. (1988)

1. Pyramidal neurones in the precentral motor area of the monkey were studied using intracellular techniques. Pyramidal tract neurones (PTNs) were identified by antidromic activation from the cerebral peduncles or medullary pyramids. Orthodromic responses were recorded in PTNs and in other pyramidal neurones when antidromic volleys were set up by stimulation of the peduncles or pyramids. The neurones were then labelled by intracellular ionophoresis of horseradish peroxidase and their morphology examined. All neurones studied were identified as pyramidal cells according to their morphology. 2. Six pyramidal neurones located in lamina V were well stained; they included two fast PTNs and two slow PTNs. The morphology of all pyramidal neurones in this lamina (fast PTNs, slow PTNs and those pyramidal cells that were not antidromically characterized) was essentially similar. A single apical dendrite branched as it ascended and its terminals arborized subpially. Numerous lateral and oblique dendrites branched from the apical dendrites in lamina V and near its border with lamina III: short basal dendrites arborized in the vicinity of the soma in lamina V. Long basal dendrites had a wider field of arborization in lamina V and sometimes extended into lamina VI. 3. Three to five collaterals arose from the axon of lamina V cells in the cortex and arborized in laminae V and VI. Short collateral branches arborized in the vicinity of the soma in the region of the basal and lateral dendrites. Long collateral branches could be traced over long distances (often more than 1 mm). One pyramidal neurone in this lamina (a fast PTN) lacked short collateral branches from the axon. 4. Four pyramidal neurones in lamina III were stained well. The dendritic morphology of all these neurones was similar. Apical dendrites branched as they ascended and terminated subpially. Lateral and basal dendrites formed a column of dendritic branches around the soma. No long basal dendrites were seen. 5. The number and arborization of intracortical collaterals from the axon of lamina III cells varied widely; from three to twelve collaterals arose from the axon. The biggest arbor of collateral branches involved all the cortical laminae and was about 3 mm wide mediolaterally, while the smallest arbor was restricted mainly to lamina III in the vicinity of the soma. One neurone in this lamina also lacked short collateral branches from the axon. 6. Antidromic volleys from the pyramidal tract evoked excitatory responses in fast PTNs, predominantly inhibitory responses in slow PTNs and either excitatory or inhibitory responses in other pyramidal neurones in lamina V.(ABSTRACT TRUNCATED AT 400 WORDS)
Poster: Compiler-assisted Automatic Checkpointing for Transiently-powered Embedded Devices (2017)

We present compiler-assisted automatic checkpoint strategies to allow transiently-powered embedded sensing devices efficiently save the system’s state onto non-volatile memory before energy is exhausted. Our solution operates at compile-time with no developer intervention based on the control-flow graph (CFG) of a program, while adapting to varying levels of remaining energy and all possible program executions at run-time. In addition, the underlying design rationale allows the system to spare the energy-intensive probing of the energy buffer whenever possible.
Getting the most out of PRHO shadowing (2004)

Shadowing placements are often seen as an extension of the summer holiday, but if done wisely they can actually be one of the most useful preparations for preregistration house officer (PRHO) survival. Here are our tips.
