Measurement of 3D Visual Fatigue Using Event-Related Potential (ERP): 3D Oddball Paradigm (2008)

Rare tools to measure 3D visual fatigue that is critical in the study of 3D human factor have been examined for their reliability and validity. The purpose of the present research was to develop a paradigm to measure 3D visual fatigue using background EEG and ERP signals. We have developed "3D oddball paradigm" that revealed the effect of binocular parallax and presentation duration on 3D visual fatigue. Subjective 3D visual fatigue was also measured. Power of beta frequencies increased as watching duration increased and it was much stronger in 3D rather than in 2D condition. More importantly, P700 delayed as watching duration increased as well as in 3D rather than in 2D condition. Similar pattern of results was obtained in the measured subjective 3D visual fatigue. These results suggest that the 3D oddball paradigm would measure 3D visual fatigue correctly and reliably.
Cytotoxicity of heated chrysotile (1974)

Cytotoxicity and hemolysis were studied in chrysotile and quartz. The biological activity of the surface seemed to be different between chrysotile and quartz. Quartz lost its cytotoxicity on heating over about 500 degrees C. However chrysotile showed remarkable toxicity and induced hemolysis on heating between 650 and 800 degrees C, compared with the original unheated specimens. The mice injected intraperitoneally with minerals heated in this temperature range generally died within 48 hr after injection, while those injected with untreated chrysotile or chrysotile heated in the other heat ranges did not. The products in this range were highly disorded materials. It was assumed that the change of biological effects resulting from heat treatment may be related to the disordered state of chrysotile in the process of transformation into forsterite. The relationship between chemical character and cytotoxicity of the heated chrysotile specimens was also studied.
The influence of a yacht's heeling stability on optimum sail design (1997)

This paper presents fundamental results concerning the optimum design of yacht sails and masts. The aerodynamics of a high aspect ratio sail in uniform flow is analysed using lifting line theory to maximise thrust for a given sail area. The novel feature of this work is that thrust is optimised subject to the constraint that the aerodynamic heeling moment generated by the sail is balanced by the righting moment due to hull buoyancy (and the weight of the keel). Initially, the heel angle is therefore unknown, and determined as part of the solution process. Under the assumption of small heel angle, the problem reduces to minimising a quadratic form in the Fourier coefficients for the circulation distribution along the mast, and a simple analytic solution can be derived. It is found that if the mast is too high, the upper section is unused, and as a consequence there is a theoretically ideal mast height for a yacht of given heeling stability. Under the constraints of given sail area and heeling equilibrium it is found that no advantage is to be gained by allowing reverse circulation near the top of the mast. Various implications for yacht performance are discussed.
A biomimetic underwater vehicle actuated by waves with ionic polymer–metal composite soft sensors (2015)

The ionic polymer-metal composite (IPMC) is a soft material based actuator and sensor and has a promising potential in underwater application. This paper describes a hybrid biomimetic underwater vehicle that uses IPMCs as sensors. Propelled by the energy of waves, this underwater vehicle does not need an additional energy source. A physical model based on the hydrodynamics of the vehicle was developed, and simulations were conducted. Using the Poisson-Nernst-Planck system of equations, a physics model for the IPMC sensor was proposed. For this study, experimental apparatus was developed to conduct hydrodynamic experiments for both the underwater vehicle and the IPMC sensors. By comparing the experimental and theoretical results, the speed of the underwater vehicle and the output of the IPMC sensors were well predicted by the theoretical models. A maximum speed of 1.08 × 10(-1) m s(-1) was recorded experimentally at a wave frequency of 1.6 Hz. The peak output voltage of the IPMC sensor was 2.27 × 10(-4) V, recorded at 0.8 Hz. It was found that the speed of the underwater vehicle increased as the wave frequency increased and the IPMC output decreased as the wave frequency increased. Further, the energy harvesting capabilities of the underwater vehicle hosting the IPMCs were tested. A maximum power of 9.50 × 10(-10) W was recorded at 1.6 Hz.
Printed geodesic lenses in glass with ion-exchanged film waveguides (1982)

Geodesic lenses are printed into glass substrates by using pressurised nitrogen and precisely machined preforms made of synthetic graphite. Multimode film waveguides of about 50 μm depth are fabricated by a field-assisted silver ion exchange. The geometrical tolerances, the spot size and the losses are measured.
Foreign body detection in food materials using compton scattered x-rays (2002)

This thesis investigated the application of X-ray Compton scattering to the problem of foreign body detection in food. The methods used were analytical modelling, simulation and experiment. A criterion was defined for detectability, and a model was developed for predicting the minimum time required for detection. The model was used to predict the smallest detectable cubes of air, glass, plastic and steel. Simulations and experiments were performed on voids and glass in polystyrene phantoms, water, coffee and muesli. Backscatter was used to detect bones in chicken meat. The effects of geometry and multiple scatter on contrast, signal-to-noise, and detection time were simulated. Compton scatter was compared with transmission, and the effect of inhomogeneity was modelled. Spectral shape was investigated as a means of foreign body detection. A signal-to-noise ratio of 7.4 was required for foreign body detection in food. A 0.46 cm cube of glass or a 1.19 cm cube of polystyrene were detectable in a 10 cm cube of water in one second. The minimum time to scan a whole sample varied as the 7th power of the foreign body size, and the 5th power of the sample size. Compton scatter inspection produced higher contrasts than transmission, but required longer measurement times because of the low number of photon counts. Compton scatter inspection of whole samples was very slow compared to production line speeds in the food industry. There was potential for Compton scatter in applications which did not require whole-sample scanning, such as surface inspection. There was also potential in the inspection of inhomogeneous samples. The multiple scatter fraction varied from 25% to 55% for 2 to 10 cm cubes of water, but did not have a large effect on the detection time. The spectral shape gave good contrasts and signal-to-noise ratios in the detection of chicken bones.
1H, 15N backbone assignment and comparative analysis of the wild type and G12C, G12D, G12V mutants of K-Ras bound to GDP at physiological pH (2019)

K-Ras protein is a membrane-bound small GTPase acting as a molecular switch. It plays a key role in many signal transduction pathways regulating cell proliferation, differentiation, survival, etc. It alternates between its GTP-bound active and the GDP-bound inactive conformers regulated by guanine nucleotide exchange factors and GTPase activating proteins. Its most frequent oncogenic mutants are G12C, G12D, and G12V that have impaired GTPase activity, thus induce malignant tumors. Here we report the resonance assignment of the backbone <sup>1</sup>H and <sup>15</sup>N nuclei of K-Ras wildtype, G12C, G12D and G12V proteins' catalytic G domain (1-169 residues) in GDP-bound state, and <sup>13</sup>C of backbone and side chains of G12C mutant at physiological pH 7.4. Triple resonance data were used to get secondary structure information and backbone dynamics of G12C, the best-known drug target among K-Ras mutants. Simultaneous investigation of G12C, G12D and G12V mutants, along with the wild type form at the very same conditions allowed us to perform a comprehensive analysis based on the combined chemical shifts to reveal the effect of mutation at G12 position on structure. Intriguingly, the G12C and G12V mutants found to be structurally very similar at the three most important regions of K-Ras (P-loop, Switch-I, Switch-II), while the G12D mutant significantly differs at P-loop and Switch-II from the wildtype as well as G12C and G12V mutants. However, in Switch-I it hardly deviates from the wildtype protein.
Privacy Preserving Co-operative Statistical Analysis for Computing Medical Data (2014)

Mobile Healthcare (m-Healthcare) system has been envisioned as an important application of pervasive computing to improve health care quality and save lives of people, where small wearable or implantable body sensor nodes and smart phones are utilized to provide remote healthcare monitoring to people who have chronic medical conditions such as diabetes and heart disease , in a mobile healthcare system, medical users are no longer needed to be monitored within home or hospital environments. Instead, after being equipped with smart phone and wireless body sensor network (BSN) formed by body sensor nodes, the medical users can walk outside and receive the high-quality healthcare monitoring from medical professionals anytime and anywhere. Each mobile medical user’s personal health information (PHI) such as heart beat, blood sugar level, blood pressure and temperature , can be first collected by the BSN, and then generated by smart phone via Bluetooth. Finally, they are transmitted to the remote healthcare center using the nearby access point via wi-fi network. When the PHI is being transmitted there are many possibilities that a third person may hack the information. To avoid this scenario we introduce a new Privacy Preserving Scalar Product Computation (PPSPC) technique in the client side also.
IGF binding proteins: regulation of cellular actions. (1992)

The recent purification and structural analysis of the six forms of insulin-like growth factor binding proteins has opened up the possibility of studying their mechanism of action at the cellular level. While a great deal of information has been published regarding control of secretion of these proteins by cells, their modulation of the target cell actions of the IGFs remains incompletely studied. Both IGFBP-1 and 3 have been shown to be bipotential regulators. Using one set of culture conditions, both proteins appear to inhibit IGF-mediated growth while if other conditions are used they appear to stimulate growth. IGFBP-2, 5 and 6 have been less well studied in this regard, although several studies showing growth inhibition with IGFBP-2 have been published. IGFBP-4 appears to be consistently inhibitory and no studies showing stimulation have been published to date. Recent research has focused on the reason for these bifunctional effects. Clearly the ability to adhere to cell surfaces appears to be one important property of these proteins that results in their ability to potentiate or inhibit growth. Likewise, phosphorylation of IGFBP-1 on serine residues appears to be a structurally modifying change which results in altered growth regulation. The future will no doubt uncover other post-translational modifications that result in modulation of biologic activity.

<p>Acetyl-L-carnitine in painful peripheral neuropathy: a systematic review</p> (2019)

Acetyl-L-carnitine (ALC) has shown a neuroprotective effect in patients with peripheral neuropathies of different etiologies. Preclinical studies demonstrated a central anti-nociceptive action, both in neuropathic and nociceptive pain models. The present review aims to provide the knowledge on the efficacy of ALC in patients with painful peripheral neuropathy, based on the evidence. Consistent with the PRISMA statement, authors searched PubMed, Embase and the Cochrane Database of Systematic Reviews for relevant papers, including those issued before April 2018. Two authors independently selected studies for inclusion and data extraction: only trials including patients with a diagnosis of peripheral neuropathy and involving at least 10 patients were considered for the purposes of this review. Fourteen clinical trials were revised, to provide the level of evidence for neuropathy. To assess the global efficacy of ALC in painful peripheral neuropathy, a meta-analysis of four randomized controlled trials was performed. Mean difference in pain reduction as measured on a 10-cm VAS, and 95% CIs were used for pooling continuous data from each trial. Four randomized controlled trials tested ALC in patients with neuropathy secondary to diabetes and to antiretroviral therapy for HIV. Compared to placebo, ALC produced a significant pain reduction equal to 20.2% (95% CI: 8.3%-32.1%, <i>P</i><0.0001) with respect to baseline. Clinical trials also showed beneficial effects on nerve conduction parameters and nerve fiber regeneration, with a good safety profile. These data indicate that ALC provides an effective and safe treatment in patients with painful peripheral neuropathy. We recommend further studies to assess the optimal dose and duration of the therapeutic effect (also after treatment withdrawal).

Endogenous lung stem cells: what is their potential for use in regenerative medicine? (2010)

Advances in stem cell technologies in recent years have generated considerable interest in harnessing the potential of adult and embryonic stem cells in regenerative medicine. Stem cell-based therapies are a particularly attractive option for the treatment of intractable lung diseases for which current therapies are essentially palliative. Proof-of-principle experiments in animal models demonstrate the efficacy of exogenous stem cells in mediating lung repair by attenuating fibrotic responses to injury, but also suggest that their ability to contribute to lung epithelial regeneration and repair is limited. Consequently, attention has turned to endogenous lung stem cells as targets or vehicles for the delivery of lung regenerative therapies. In this article, we discuss the potential and promise of endogenous lung stem cells in regenerative medicine, and the problems and challenges faced by researchers and clinicians in harnessing their potential to repair the lung.

Benzotriazole as a Corrosion Inhibitor for Immersed Copper (1973)

The use of benzotriazole as a corrosion inhibitor is briefly reviewed and the theory of its mode of protection for copper in aqueous conditions is considered. The solubility has been found to increase with temperature, and the addition of benzotriazole decreased the pH and increased the conductivity of distilled water. It has been shown to be a good inhibitor for copper and brass when added to many acidic, neutral, and alkaline solutions, and it appears to act as a weak buffer. Copper surfaces pretreated with a hot solution of benzotriazole were found to have an increased resistance to staining in atmospheric environments and also to corrosion when immersed in many solutions of acids and salts. The inhibitor reduced the dissolution of copper in water and thus the pitting of aluminum foil immersed in the same water.
Ultrasmall Overlapped Arrayed-Waveguide Grating Based on Si Nanowire Waveguides for Dense Wavelength Division Demultiplexing (2006)

A novel design for an ultrasmall arrayed-waveguide grating (AWG) demultiplexer based on a Si nanowire waveguide is presented. The two free propagation regions (FPRs) are overlapped so that the structure becomes more compact than the layout of a conventional design. Each half of an arrayed waveguide includes three straight sections and two bending sections, and all these sections are connected smoothly in sequence. Some recursive formulas for determining the geometrical parameters of the novel layout are derived. Numerical simulation results are given
“An application of simulation models to corporate planning processes” (1973)

A family of timeshared computer models written in APL have been developed in an effort to link the functional areas for communication, planning and control purposes. The models incorporate the concepts and tools of simulation, forecasting, long-range planning and probabilistic budgeting. Developed in a short time span and at low cost, they are widely used at XEROX in both corporate and region offices in both the U.S. and Canada. Under development is a system of statistical and econometric models. The paper discusses the approaches used to design, implement and involve the functional managers in building and utilizing the models.

RECURRENT INHIBITION OF α - MOTONEURONS IN PATIENTS WITH UPPER MOTOR NEURON LESIONS (1982)

The recurrent inhibition of alpha-motoneurons by Renshaw cells, brought about by a conditioning reflex discharge, was estimated by measuring the amplitude of a test reflex which involved only those soleus motoneurons which had already fired in response to the conditioning volley. The results obtained in 95 patients with upper motor neuron disease and in 31 normal subjects were compared. At rest, there was no evidence for a decrease in the excitability of Renshaw cells: on the contrary, recurrent inhibition, if it changed at all, was increased in 55 out of 95 patients. In most patients the changes in Renshaw cells excitability which occur during postural or voluntary contractions in normal subjects were not found. We conclude that changes in recurrent inhibition are not responsible for the hyperexcitability of the stretch reflex which characterizes human spasticity. On the other hand, the paralysis of the supraspinal control of Renshaw cells, which normally accompanies voluntary movements, could account in part for two difficulties exhibited by spastic patients: in grading the strength of a muscular contraction, and in regulating reciprocal Ia inhibition according to the requirements of a voluntary movement.
A Bibliography of Contemporary Writings on The Natural History of Natal and Zululand in the 19th and Early 20th Centuries (1990)

Nineteenth century Natal and Zululand presented to colonial officials, settlers, traders and visitors a vast and undocumented world of natural history. The southeast African landscape exhibited geological and climatological features, and abounded with fauna and flora which had not been described or recorded in the annals of European natural history and science. 

Gradually however, thanks to the efforts of the Colony's inhabitants and visitors, many of whom had little or no scientific training, the landscape of Natal and Zululand came to the attention of natural scientists in Europe. Observations and experiences of local inhabitants and visitors were recorded and published in European journals of science and natural history, and specimens catalogued in Europe's museums, zoos and botanical gardens. The scientific documentation and classification of the fauna, flora, climate and geology followed.
Emergency medicine (1991)

Cardiac and brain resuscitation have continued to be dominant areas for research in 1990. The spectacular failure of cardiopulmonary resuscitation to successfully resuscitate all but a small minority of patients has motivated a number of investigations on the method of performance of advanced cardiac life support. Animal studies have demonstrated that the empiric dosage of epinephrine in cardiac arrest may be inadequate to produce sufficient cardiac and cerebral perfusion pressures during cardiopulmonary resuscitation and that larger doses may be more successful. Human studies show that the coronary perfusion pressure achieved during cardiopulmonary resuscitation is the most important predictor of successful resuscitation.<sup>1</sup>Paradis et al<sup>1</sup>studied 100 patients in cardiac arrest to determine the relationship of coronary perfusion pressure to return of spontaneous circulation. No patients with a coronary perfusion pressure of less than 15 mm Hg had return of spontaneous circulation. Arterial blood gas values had a poor
