Heart rate variability as an assessment of cardiovascular status (1996)

In summary, HRV is a useful tool for cardiovascular risk stratification and assessment of sympathovagal balance. It has been shown to be a useful investigative tool in anesthesia to study autonomic balance and dysfunction but has limitations with regard to a depth-of-anesthesia monitor because of the confounding effects of multiple drugs and surgical stimuli. When assessing HRV, it is important to understand the limitations of the methodology. In particular, absolute power is not a surrogate of autonomic tone, but the relationship between the power in the different frequency bands may better reflect autonomic balance.
Influence of Picking Stage and Storage Type on the Fruit Respiration Change and Panel Test in 'Wonhwang', 'Hwasan', and 'Mansoo' Pear (2004)

Three kinds of Asian pear fruits were harvest at conventional ripening stage and several days earlier than ripening ones including ‘Wonhwang’, ‘Hwasan’ and ‘Mansoo’ represented the early-season, mid-season, and late-season mature cultivars, respectively. In the ambient temperature storage, respiratory pattern of ‘Wonhwang’ cultivar showed some climacteric, but ‘Hwasan’ and ‘Mansoo’ showed non-climacteric. So, the controlled atmosphere (CA) effect was not clear in ‘Hwasan’ and ‘Mansoo’. The fruit firmness of ‘Wonhwang’ pear was well-maintained in CA storage compared with low temperature storage. According to the fruit firmness, incidence of core breakdown, and value of sensory test, the proper storage periods of ‘Wonhwang’ pear was 15­20 days in ambient temperature, 120 days in low temperature, and 160 days in CA storage. And marketable quality was kept properly for 20­30 days in ambient, 120­160 days in low temperature, and 160­180 days in CA storage of ‘Hwasan’ pear. Storage periods was longer in ‘Mansoo’ fruit that ‘Hwasan’ pear stored at ambient temperature. But in low temperature storage, the proper storage periods was about the same as ‘Hwasan’ pear. The storage periods of ‘Mansoo’ pear was 200 days in CA storage.
Voltage-tuning in multi-color quantum well infrared photodetector stacks (1996)

A systematic study of stacked quantum well infrared photodetectors is undertaken to improve the understanding of the voltage-tunable multi-color spectral response. The multi-color capability is achieved by sequentially growing conventional one color detectors, separated by conducting layers. The behavior of the stacked devices is proven to correspond to the individual detectors simply acting in series with each other. The dc resistance, photocurrent and dynamic resistance characteristics of the individual detectors are examined and correlated with the voltage-tuning in the stack.
A Brief Commentary: Electroacupuncture May Relax the Contraction of Sphincter of Oddi (2001)

Animal studies have shown that acupuncture can affect the function of the sphincter of Oddi, a smooth muscle encircling major papilla located at the second portion of the duodenum that regulates the flow of bile and pancreatic juice. This study of thirteen patients was the first to observe the effects of acupuncture on sphincter of Oddi motility in humans. Stimulation of the acupuncture point GB-34, which is known to Oriental medicine as an acupoint with effect on the biliary system, showed reversible inhibition of sphincter of Oddi contractions. In contrast, stimulation of a nonspecific control acupoint did not induce significant change. This study suggests that acupuncture may be one alternative treatment for patients with sphincter of Oddi dysfunction.

Expert system and integer programming formulations of an NP-complete constraint satisfaction problem are contrasted in terms of performance, ability to encode complex preferences, control of reasoning, and supporting incremental modification of solutions in response to changing input data.
The airborne open system interconnection data link test facility (2003)

The author describes the activities of the US Federal Aviation Administration (FAA) Technical Center in the joint government-industry Aeronautical Telecommunications Network (ATN) project. The ATN is defined as a network architecture that allows use of multiple communication subnetworks and provides a path for oceanic, international, and domestic data link services. A major goal of the design process is the separation of the user applications from the communications and interoperability among diverse data link subnetworks. This project is oriented toward the eventual provision of a world-wide packet switched architecture for the networking of International Organization for Standardization (ISO) Open System Interconnection (OSI) conformant host computer and systems and router intermediate systems.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Enhancement of Nuclear Fusion in Plasma Oscillation Systems (2022)

Concepts of dynamic oscillations of positive and negative ions to enhance fusion reactions are examined in this paper. Collective oscillations of positive and negative ions produce large oscillating electrostatic fields and could provide a significant reduction of the Coulomb potential barrier between the two interacting species (such as hydrogen anion H− and B+ in the hydrogen-boron fusion reaction). The negative hydrogen ions can be produced by populating low-temperature electrons around the neutral hydrogen atoms in a rotation chamber. The existence of H− ensures the stability of the plasma and the effectiveness of fusion interactions between H− and B+. In this paper, theoretical analyses of such oscillations systems will be presented and the conditions for fusion enhancement are discussed.
Unsupervised learning of generalized names (2002)

We present an algorithm, NOMEN, for learning generalized names in text. Examples of these are names of diseases and infectious agents, such as bacteria and viruses. These names exhibit certain properties that make their identification more complex than that of regular proper names, NOMEN uses a novel form of bootstrapping to grow sets of textual instances and of their contextual patterns. The algorithm makes use of competing evidence to boost the learning of several categories of names simultaneously. We present results of the algorithm on a large corpus. We also investigate the relative merits of several evaluation strategies.

The Role of Intracellular Linkers in Gating and Desensitization of Human Pentameric Ligand-Gated Ion Channels (2014)

It has recently been proposed that post-translational modification of not only the M3-M4 linker but also the M1-M2 linker of pentameric ligand-gated ion channels modulates function in vivo. To estimate the involvement of the M1-M2 linker in gating and desensitization, we engineered a series of mutations to this linker of the human adult-muscle acetylcholine receptor (AChR), the α3β4 AChR and the homomeric α1 glycine receptor (GlyR). All tested M1-M2 linker mutations had little effect on the kinetics of deactivation or desensitization compared with the effects of mutations to the M2 α-helix or the extracellular M2-M3 linker. However, when the effects of mutations were assessed with 50 Hz trains of ∼1 ms pulses of saturating neurotransmitter, some mutations led to much more, and others to much less, peak-current depression than observed for the wild-type channels, suggesting that these mutations could affect the fidelity of fast synaptic transmission. Nevertheless, no mutation to this linker could mimic the irreversible loss of responsiveness reported to result from the oxidation of the M1-M2 linker cysteines of the α3 AChR subunit. We also replaced the M3-M4 linker of the α1 GlyR with much shorter peptides and found that none of these extensive changes affects channel deactivation strongly or reduces the marked variability in desensitization kinetics that characterizes the wild-type channel. However, we found that these large mutations to the M3-M4 linker can have pronounced effects on desensitization kinetics, supporting the notion that its post-translational modification could indeed modulate α1 GlyR behavior.
Allergic rhinitis in northern vietnam: increased risk of urban living according to a large population survey (2011)

Allergic rhinitis ever was considerably more common in the urban area. Nasal blocking and runny nose was each reported by about one third of the studied sample with no major urban-rural difference. Further, exposure to air pollution at work was significantly associated with allergic rhinitis ever, nasal blocking and runny nose.
Automatic Optical Inspection for Surface Mounting Devices with IPC-A-610D compliance (2011)

Automated Optical Inspection (AOI) Systems are commonly used on Printed Circuit Boards (PCB) manufacturing process. The use of this technology has been proved to be highly efficient on process improvements and quality achievements. The most difficult point on Surface Mounting Devices (SMD) inspection is the solder joint due to their specular reflections. Several studies have been made to improve this situation. In this paper, it is presented a solder joint classification system based on IPC-A-610D (Acceptability of Electronics Assemblies).
Chip-based adaptive skin color detection using trajectory constraints on hue (2014)

Abstract Background In a construction site, the safety of workers can be better secured if vehicle or robot can be properly maneuvered by using image-based gesture guidance. This kind of semi-automatic motion control is based on the features extracted in colors, outlines, textures, and motion intentions. Among these features, detecting worker’s skin color on face and hands could serve as an essential method for enabling robot to determine the region of interest (ROI). However, the performance of skin detection is usually unreliable due to interferences from reflections and shadows. Although many efficient skin color detection methods had been developed in past years, those are mostly based on complicated learning and statistical processes and are unsuitable for embedded systems. The exploration of a concise and efficient skin color detector, therefore, becomes a challenge for applications in mobile robots. Method In this paper, we propose a novel adaptive skin detector on face and hands as a fundamental capability of a gesture tracking system. This approach enhances the detection performance of traditional HSV color space but only requires a low computing power. For the design criteria of small size, low-power, low-cost, and minimum computing resource usages on mobile robots, the entire detecting system is built on single field-programmable-gate-array (FPGA) chip. Meanwhile, besides the contributions of adaptive algorithms and FPGA chip designs, the proposed skin detector also employs a touch screen to designate expected skin color of worker as the human-robot interaction (HRI) in real-time. Results The chip design of the FPGA is based on hardware circuits in register-transfer-level (RTL) for real-time image processing. A reasonable amount of hardware resource usages of FPGA have consumed 8% of logic elements (LEs) and 1.4% for embedded random access memory (RAM). Demonstrations with various pictures had indicated that sufficient ROI can be efficiently identified by using the proposed adaptive skin color detector. Conclusions According to our experimental results, the proposed adaptive skin detection can work well for non-ideal illumination. It has demonstrated the reliability and feasibility on supporting the embedded robotic control in the future.
Design techniques for soft-error mitigation (2010)

In nanometric technologies, circuits are increasingly sensitive to various kinds of perturbations. Soft-errors, a concern in the past for space applications, became a reliability issue at ground-level. Alpha particles and atmospheric neutrons induce single event upsets (SEU) affecting memory cells, latches and flip-flops, and single event transients (SET) initiated in the combinational logic and captured by the associated latches and flip-flops. To face this challenge, a designer must dispose a variety of soft-error mitigation schemes adapted to various circuit structures, design architectures and design constraints. In this paper, we describe several SEU and SET mitigation schemes that could help designers to meet their reliability constraints.
Neurobiology, Pathophysiology, and Treatment of Melatonin Deficiency and Dysfunction (2012)

Melatonin is a highly pleiotropic signaling molecule, which is released as a hormone of the pineal gland predominantly during night. Melatonin secretion decreases during aging. Reduced melatonin levels are also observed in various diseases, such as types of dementia, some mood disorders, severe pain, cancer, and diabetes type 2. Melatonin dysfunction is frequently related to deviations in amplitudes, phasing, and coupling of circadian rhythms. Gene polymorphisms of melatonin receptors and circadian oscillator proteins bear risks for several of the diseases mentioned. A common symptom of insufficient melatonin signaling is sleep disturbances. It is necessary to distinguish between symptoms that are curable by short melatonergic actions and others that require extended actions during night. Melatonin immediate release is already effective, at moderate doses, for reducing difficulties of falling asleep or improving symptoms associated with poorly coupled circadian rhythms, including seasonal affective and bipolar disorders. For purposes of a replacement therapy based on longer-lasting melatonergic actions, melatonin prolonged release and synthetic agonists have been developed. Therapies with melatonin or synthetic melatonergic drugs have to consider that these agents do not only act on the SCN, but also on numerous organs and cells in which melatonin receptors are also expressed.

Atmospheric excitation of polar motion (2010)

The polar motion excited by the fluctuation of global atmospheric angular momentum (AAM) is investigated. Based on the global AAM data, numerical results demonstrate that the fluctuation of AAM can excite the seasonal wobbles (e.g., the 18-month wobble) and the Chandler wobble, which agree well with previous studies. In addition, by filtering the dominant low frequency components, some distinct polar wobbles corresponding to some great diurnal and semi-diurnal atmospheric tides are found.
Carbon Capture and Storage (CCS) policy for China: Implications from Some Representative Countries and Regions (2014)

In recent years carbon capture and storage (CCS) emerged as a promising low-carbon technology to tackle climate change by storing the captured CO2 underground. Varied countries and regions have promulgated or proposed specific CCS policies to accommodate with CCS development in their jurisdictions. However, CCS policies seem to be in a vacancy in China. Presented in this paper is a general overview for CCS policies in some representative countries and regions including the United States, Canada, United Kingdom and Australia that are making substantial contributions to the establishment of CCS policy framework in their own jurisdictions as well as their implications for construction of CCS policy framework in China. CCS policies in China are also reviewed and compared with those of the typical economic entities in detail. The result demonstrates that prescriptive standards and regulations, economic incentives as well as supportive measures are not sufficient to smooth CCS deployment in China. Policy recommendations are thus raised to guide CCS progress in China, with a suggested policy package including enactment of CCS regulatory framework, multi-source funding mechanism, elaborated measures to raise public awareness of CCS. The outcome has essential policy implications supportive to a further expansion of CCS deployment in China.
Anticytotoxin activity of bovine sera and body fluids against Pasteurella haemolytica A1 cytotoxin. (1984)

Toxin neutralizing activity of bovine sera and body fluids against Pasteurella haemolytica type A1 cytotoxin was evaluated by 51Cr release assay using bovine peripheral blood mononuclear leukocytes as the target cells. Sera collected from precolostral calves did not exert anticytotoxin activity at 10(-1) or higher dilutions, whereas randomly selected complement fixing antibody-negative sera neutralized on average over 90% of cytotoxin activity at the 10(-1) dilution and less than 50% of the toxin activity at 10(-2) or higher serum dilutions. Nasal secretions and lung washings of some of the cattle tested also contained cytotoxin neutralizing activity. The antibody nature of the cytotoxin neutralizing activity was demonstrated by its neutralization with bovine immunoglobulin G2 purified from pooled seropositive sera. Sera from a group of cattle which were vaccinated with a potassium thiocyanate extract of P. haemolytica, but which subsequently developed fibrinous pneumonia after aerosol challenge with bovine herpesvirus 1 and P. haemolytica, had significantly lower anticytotoxin activity than sera from another group of cattle which did not develop the disease after similar vaccination and challenge. Cattle which survived a natural outbreak of shipping fever had higher anticytotoxin activity than those having fibrinous pneumonia in the aforementioned experimental group, although there was no statistical difference between them and a randomly selected CF seronegative group. It is probable that this cytotoxin neutralizing antibody exerts a beneficial effect in protection of cattle against pneumonic pasteurellosis.

Blind source separation of convolutive mixtures (2002)

When a priori information about the propagation or the geometry of the array are not available, the model can be generalized to a blind source separation problem. It supposes the statistical independence of the sources and their non-Gaussianity. The observed signals are assumed to be convolutive mixtures of wide-band sources. Several criteria of source separation are studied which are based on the cancellation of different fourth-order cross-cumulants. For these criteria, we show in which conditions the separation is achieved. Results on real data illustrate the proposed methods.
Temporal Evolution of Pleural Fibrosis Induced by Intrapleural Minocycline Injection (1995)

Minocycline is as effective as tetracycline in inducing pleural fibrosis, but the long-term pleural changes induced by minocycline are unknown. The objective of this study was to evaluate in rabbits the evolution of the pleural changes induced by the intrapleural instillation of minocycline. Under light anesthesia, minocycline at 10 mg/kg in a total volume of 2 ml of bacteriostatic saline solution was injected into the right pleural space of 25 male rabbits. The animals were sacrificed in groups of five at 15 d and 1, 2, 4, and 6 mo. Macroscopic and microscopic examinations of the pleura were performed for evidence of pleural fibrosis and inflammation. Similarly, the underlying lung was also examined for microscopic alveolar fibrosis and inflammation. During the 6-mo observation period there was no significant change in the degree of pleural fibrosis. In contrast, microscopic pleural inflammation, alveolar fibrosis, and alveolar inflammation all decreased significantly over the observation period. In conclusion, intrapleural minocycline injection results in persistent pleural fibrosis at 6 mo. It remains to be determined whether the pleural fibrosis will persist beyond this period.
