λ-ADJUST scheduling algorithm for optical switches with reconfiguration delay (2004)

Using optical technology brings with it advantages such as scalability, high bandwidth and power consumption for the design of switches/routers. However, reconfigurating the optical fabric of these switches requires significant time under current technology. Conventional slot-by-slot scheduling may severely cripple the performance of these switches due to its frequent request for fabric reconfiguration. A more appropriate way is to use a time slot assignment (TSA) scheduling approach. The switch gathers the incoming traffic periodically and schedules them in batches, while trying to minimize the transmission time. This optical switch scheduling (OSS) problem is defined in this paper and it is NP-complete. Earlier TSA algorithms normally assume the reconfiguration delay to be either zero or infinity for simplicity. To this end, we propose a /spl lambda/-ADJUST algorithm, which breaks this limitation and self-adjusts with different reconfiguration delay values. The algorithm runs at O(/spl delta/N/sup 2/logN) time complexity, guarantees a 100% throughput and a bounded worst case delay. In addition, it outperforms existing TSA algorithms across a large spectrum of reconfiguration values.
An LTCC Interference Cancellation Device for Closely Spaced Antennas Decoupling (2018)

A compact interference cancellation device (ICD) offering a great decoupling for a pair of closely overlapped antennas and enhancing the throughput of the multi-input-multi-output (MIMO) system is proposed. The device is implemented using semi-lumped components with a compact size of 1.6 mm <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\times \,\, 0.8$ </tex-math></inline-formula> mm <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\times \,\, 0.6$ </tex-math></inline-formula> mm with the help of the low temperature co-fired ceramics multilayer fabrication technology. The proposed topology is applied to enhance the overall data throughput of a MIMO system with two overlapped antennas sharing a reduced clearance region. A MIMO antenna system consisting of two conventional coupled antennas locating at the same plane, and its counterpart containing two overlapped antennas integrated with the ICD chip are fully investigated. The experimental results demonstrate that around 10% overall throughput improvement of the MIMO system is obtained across the 2.4 GHz band while the ground clearance area of the antennas has been shrunk by 50%. It is also proved that the presented ICD device is a good candidate in applications of mobile terminals and wireless communication devices with very compact volumes.
Tranexamic Acid for Acute Hemorrhage: A Narrative Review of Landmark Studies and a Critical Reappraisal of Its Use Over the Last Decade (2019)

The publication of the Clinical Randomization of an Antifibrinolytic in Significant Hemorrhage-2 (CRASH-2) study and its intense dissemination prompted a renaissance for the use of the antifibrinolytic agent tranexamic acid (TXA) in acute trauma hemorrhage. Subsequent studies led to its widespread use as a therapeutic as well as prophylactic agent across different clinical scenarios involving bleeding, such as trauma, postpartum, and orthopedic surgery. However, results from the existing studies are confounded by methodological and statistical ambiguities and are open to varied interpretations. Substantial knowledge gaps remain on dosing, pharmacokinetics, mechanism of action, and clinical applications for TXA. The risk for potential thromboembolic complications with the use of TXA must be balanced against its clinical benefits. The present article aims to provide a critical reappraisal of TXA use over the last decade and a "thought exercise" in the potential downsides of TXA. A more selective and individualized use of TXA, guided by extended and functional coagulation assays, is advocated in the context of the evolving concept of precision medicine.

Nutrition Interventions in Aging and Age‐Associated Disease (2001)

The nutritional status and needs of elderly people are associated with age-related biological and often socioeconomic changes. Decreased food intake, a sedentary lifestyle, and reduced energy expenditure in older adults altogether become critical risk factors for malnutrition, especially protein and micronutrients. Surveys indicate that the elderly are particularly at risk for marginal deficiency of vitamins and trace elements. Changes in bodily functions, together with the malnutrition associated with advancing age, increase the risk of developing a number of age-related diseases. Chronic conditions pose difficulties for the elderly in carrying out the activities of daily living and may increase the requirements for certain nutrients due to changes in absorptive and metabolic capacity. Free radicals and oxidative stress have been recognized as important factors in the biology of aging and of many age-associated degenerative diseases. In this regard, modulation of oxidative stress by calorie restriction, as demonstrated in animal models, is suggested as one mechanism to slow the aging process and the decline of body functions. Therefore, dietary components with antioxidant activity have received particular attention because of their potential role in modulating oxidative stress associated with aging and chronic conditions. Several studies have indicated potential roles for dietary antioxidants in the reduction of degenerative disease such as vascular dementia, cardiovascular disease, and cancer. In support of epidemiological studies, our recent studies indicate that the antioxidant properties of vitamin E and polyphenols present in green tea may contribute to reducing the risk of cardiovascular disease, in part by reducing the susceptibility of low density lipoproteins to oxidation, decreasing the vascular endothelial cell expression of pro-inflammatory cytokines, and decreasing the expression of adhesion molecules and monocyte adhesion. Recently, we also demonstrated that these dietary antioxidants may have a preventive role in cancer, potentially through the suppression of angiogenesis by inhibiting interleukin-8 production and the cell junction molecule VE-cadherin. These findings concur with epidemiologic, clinical, and animal studies suggesting that the consumption of green tea and vitamin E is associated with a reduced risk of cardiovascular disease and cancer, the leading causes of morbidity and mortality among the elderly.
Ru(II) Complexes of N-Alkylated TsDPEN Ligands in Asymmetric Transfer Hydrogenation of Ketones and Imines (2009)

N-Alkylated TsDPEN derivatives bearing a small alkyl group act as highly efficient ligands in Ru(II) complexes for the asymmetric transfer hydrogenation of imines and ketones. A larger alkyl group serves to significantly reduce the activity of the catalyst; however, high enantiomeric excesses are still obtained. An X-ray crystal structure of the N-benzyl derivative reveals a conformation that permits hydrogen transfer through a six-membered transition state. A transition state structure for the imine reduction process is proposed.
Analyses of metalorganic chemical-vapor-deposition-grown AlxGa1−xAs/GaAs strained superlattice structures by backscattering spectrometry and x-ray rocking curves (1985)

Backscattering spectrometry with channeling and x-ray rocking curves have been employed to analyze metalorganic chemical-vapor-deposition-grown AlxGa1−xAs/GaAs strained superlattice structures in significant detail. Both techniques complement each other in the precise determination of composition, thickness, and strain in the individual layers of the superlattices. In addition, the sensitivity of the two techniques allows quantitative measurements of transition regions at the interfaces of various layers. Such fine probing into thin layered superlattice structures provides essential feedback in controlling their growth.

A Survey of Operating Problems Associated with Sewage Treatment Plants in Japan. (1996)

A questionaire survey was carried out in two trials to examine the overall situation on both the general operating problems of 785 sewage treatment plants in Japan and the corresponding solid-liquid failure caused by filamentous microorganisms. The results showed that operating problems had obviously occurred at about 80% of sewage treatment plants in Japan. About onethird of all operating problems experienced over the past five years was “filamentous bulking” followed by “abnormal foaming and scum”. The change of temperature, the sidestreams from the sludge treatment facilities, a large quantity of SS in pipes and the fluctuation of influent loading were regarded as the causes of “filamentous bulking”. The causes of “abnormal foaming and scum” were not as easily identified as those of “filamentous bulking”, but they were related to sludge level and nitrification in the aeration tank. From the point of the present situation of plants and their maintenance methods, the need for integrated management of both sewage and sludge treatment facilities was discussed in order to prevent the solid-liquid failure.
Cepharanthine inhibits angiogenesis and tumorigenicity of human oral squamous cell carcinoma cells by suppressing expression of vascular endothelial growth factor and interleukin-8 (2009)

Cepharanthine is a biscoclaurine alkaloid extracted from Stephania cepharantha Hayata, which is widely used for the treatment of many acute and chronic diseases, and can exert antitumor effects on several human cancer cell lines. However, little is known about the detailed mechanisms of the antitumor activity of Cepharanthine. In the present study, we determined whether Cepharanthine could suppress angiogenesis and growth of human oral squamous cell carcinoma (OSCC) cells in vitro and in vivo. Cepharanthine significantly inhibited expression of two major pro-angiogenic molecules, vascular endothelial growth factor (VEGF) and interleukin-8 (IL-8), in cultured cells and in cells implanted into the subcutaneous tissue of nude mice. Also, Cepharanthine inhibited the nuclear factor-kappaB (NF-kappaB) activity in human OSCC cells in vitro and in vivo. The decreased expression of VEGF and IL-8 correlated with decreased tumor cell growth and decreased vascularization in vitro and in vivo. These findings suggest that Cepharanthine can suppress angiogenesis and growth of OSCC cells by inhibiting expression of VEGF and IL-8 involved in the blockade of NF-kappaB activity.
Deterioration of Thermal Sprayed Aluminum Coatings on Hot Risers Due to Thermal Cycling (2004)

Abstract Thermal Sprayed Aluminum (TSA) has been widely used by the oil industry for corrosion protection of steel components in submerged, splash zone, and marine atmosphere service on offshore facilities. Excellent performance of TSA coatings on hot risers has been well documented for the Hutton TLP (installed 1984), Jolliet TLWP (1989), and in accelerated laboratory testing. Recently, rapid deterioration of TSA coatings occurred on hot marine export risers in a 2-meter segment exposed to the wave zone that induced high frequency thermal cycling. Laboratory tests have shown that this failure mechanism is enhanced by excess coating thickness and retarded by higher quality sealer.
Viscoelastic effects in small-scale indentation of biological materials (2007)

Modern developments in instrumentation and analysis have vastly increased the popularity of instrumented indentation and nanoindentation techniques for mechanical characterisation of materials. However, these techniques have been developed primarily for materials exhibiting time-independent mechanical behaviour and therefore have had limited applicability in the mechanical analysis of time-dependent biological tissues. Following a brief introduction on elastic and elastic-plastic indentation, the current paper reviews the existing analytical machinery available for indentation analysis of viscoelastic materials (as developed in the context of polymeric materials). Recent works are reviewed in which the application of viscoelastic indentation techniques is extended to small-scale testing of biological tissues.
Ecodesign of Surface Coatings: How to Conciliate Environmental and Technical Performances? (2009)

Abstract The aim of this study is to propose coatings that could potentially replace hard chromium as a means of corrosion and wear protection. Two NiCrBSi coatings are evaluated, one produced by laser cladding, the other by atmospheric plasma spraying with a post-laser treatment. Although laser-clad NiCrBSi exhibits the best technical properties, the APS coatings were found to be more environmentally justifiable based on the use of life cycle assessment (LCA) software.
Palladium-catalyzed silylation of alcohols with hexamethyldisilane (2006)

The combination of hexamethyldisilane and a catalytic amount of [PdCl(eta3-C3H5)]2-PPh3 was found to be effective for the trimethylsilylation of alcohols, where both of the two trimethylsilyl groups of hexamethyldisilane were transferred to alcohols without coproduction of any stoichiometric amount of byproduct but H2.

Thermal hydraulics in FBR cover gas related to component development. (1988)

Temperature of an upper surface of a roof slab or a shield plug of FBR should be maintained to room temperature from a view point of accessability. It is necessary to clarify the heat transfer characteristics in cover gas space, vertical annulus and insulation structure for evaluation of the design items i.e. the thermal loading, displacement, stress and so on.On the other hand many upper structural components should also be required to have movable functions. Since there is a fear that sodium is continuing to accumulate and solidification occurs in the gap of movable components, it is necessary to clarify the mass transfer characteristics and develop preventive methods.This report summarizes basic experimental results and experiences concerning the technology above mentioned.
Experiments of Microwave Ablation Based on Dual-Frequency Antenna Under Pulsed Mode (2022)

In this letter, we review the microwave ablation (MWA) under pulsed wave (PW) mode and perform the experiments by using a dual-frequency antenna. Parameters such as frequency (915 MHz or 2450 MHz), excitation power (40 W or 60 W), duty cycle (40%–60%), cycle (10 ms–100 s), and durations (5 min or 10) min are variably combined in different experimental schemes for investigation. Based on the results of these experiments, which use our super compact dual-frequency antenna and egg white as a reference tissue environment, it can be seen that PW MWA may reduce backward heating and increase ablation roundness to 0.964 (compared to a traditional continuous wave (CW) ablation roundness of 0.5). For further verification of these results and for comparison, a single-frequency antenna is also used under PW mode and the achieved ablation roundness is 0.91, which is also greater than that of 0.55 under CW mode. PW MWA can thus be considered as an effective candidate for tissue ablation during the treatment of tumors.

Combined strategies for the improvement of heterologous expression of a His-tagged Yarrowia lipolytica lipase Lip2 in Pichia pastoris (2011)

Yarrowia lipolytica lipase Lip2 (YlLip2) is an important biocatalyst for ester synthesis, biodiesel production and enantiomer resolution. The YlLip2 with an N-terminal histidine-tag (His 6-YlLip2) was successfully expressed in Pichia pastoris . Three different cultivation strategies had been compared for the production of His 6-YlLip2 by P. pastoris using a 10-l bioreactor. The results showed that His 6-YlLip2 activity and cell viability could be greatly improved by employing the combined strategies. Using a low salt medium (LSM) instead of the basal salt medium (BSM) and lowering the temperature from 28 to 25°C, the maximum His 6-YlLip2 activity and volumetric productivity were respectively increased by 55.3 and 79.8%. The production of His 6-YlLip2 and cell viability was further improved by combining sorbitol co-feeding with methanol. In this culture strategy, the maximum activity of His 6-YlLip2 reached 15,600 U/ml after 114 h of induction. The cell mortality decreased by 11.2% (while the control decreased about 27.6%) after 120 h methanol induction. The N-terminal histidine-tag brought convenience to purification. The molecular weight of His 6-YlLip2 was about 38 kDa. The pure His 6-YlLip2 presented a specific activity of 4,830 U/mg when olive oil was used as the substrate.
Active electrocaloric demonstrator for direct comparison of PMN-PT bulk and multilayer samples (2016)

One potential use of ferroelectrics is as active material in electrocaloric cooling systems. These systems promise a more energy efficient cooling process than vapor compression, thermoelectric or other current cooling systems. Currently different design types of electrocaloric cooling devices are in the focus of research. In this paper, we present an electrocaloric cooling device demonstrator working as “Active Electrocaloric Regenerator” (AER) and employing relaxor ferroelectric elements as active material. The device design is such that it allows the integration of different material systems and regenerator designs as well as a broad variation of operational parameters.
Studies on the Effect of In-cylinder flow on stratified HCCI Combustion (2017)

This article shows a research on the effect of in-cylinder flow on thermal stratified homogeneous charge compression ignition (HCCI) combustion to extend a high load limit of HCCI combustion. The study was conducted by three dimensional computational fluid dynamics coupled with simulation of chemical reactions. The in-cylinder temperature distribution was set as an initial condition. The in-cylinder flow was added before low temperature oxidation (LTO) and during high temperature oxidation (HTO), respectively. The results show that the in-cylinder flow before LTO leads to slow combustion due to heat loss to combustion chamber walls. The results also show that the in-cylinder flow during HTO is effective in fast combustion. This is mainly because in-cylinder flow expands hot burned mixture to unburned mixture, which accelerates the combustion.
"Sniffin' sticks": screening of olfactory performance. (1996)

"Sniffin' Sticks" is a new test of nasal chemosensory performance based on pen-like odour-dispensing devices. This portable test is suited for repetitive, inexpensive screening of odour identification. The test includes a forced odour-identification task for seven odours performed by means of a list of four items (multiple-choice). In 146 subjects the basic screening test was compared to a down-scaled version of the UPSIT (CC-SIT). Sniffin' Sticks exhibited a relatively higher coefficient of correlation with the subjects' age; they also demonstrated the women's superior olfactory sensitivity more pronounced when compared to men. In addition, the coefficient of correlation between age and olfactory performance was slightly higher when the sticks were used. Preliminary investigations in nine patients with impaired olfactory function (i.e., anosmic or hyposmic patients) revealed significantly lower scores in patients compared to healthy controls matched for age and sex (p < 0.001). It is concluded that Sniffin' Sticks may be useful in the routine clinical assessment of olfactory performance where both time and costs matter.
Systems research for agricultural development (2017)

Farmers in high-income countries (HICs) have historically been effective in articulating their needs–not only technological but also institutional–via more responsive research and extension systems, commodity-based groups and lobbying platforms. Since the 1970s the 'top-down' agricultural research/developmental paradigm has been criticised for excluding the farmers. It was this need that led to the emergence of farming systems research (FSR). This chapter examines the origins of FSR and the path and reasons for its evolution and transformation into what is called integrated systems research (ISR). Until the 1960s, there was little research collaboration between technical agricultural scientists, economists and anthropologists/sociologists. Methodologies for eliciting the attitudes and expertise of smallholder farmers have evolved greatly since the 1970s, thus creating more avenues for their involvement in identifying and implementing relevant research and development initiatives.
