Emerging technologies present both challenges and opportunities for national technology strategies. National governments may therefore want to monitor the technological horizon on a systematic basis. This article outlines quantitative approaches available such monitoring. Among standard types of bibliometric data, proposals publications are most likely be useful this purpose since they capture information earlier in cycle development. Patents, contrast, trail behind. Analysis can proceed...

We investigated the mechanism by which cannabinoid receptors-1 (CB1) and -2 (CB2) modulate inflammatory activities of macrophages. Real-time polymerase chain reaction showed predominant CB2 expression in freshly isolated human monocytes. PMA, a potent inducer differentiation, upregulated CB1 increased CB1:CB2 transcript ratio from 1:17.5 to 1:3 5 days culture. Immunohistochemistry that protein was colocalized CD68- CD36-positive macrophages atheroma. Through selective or...

A new protocol for preparing thioesters from the corresponding methyl esters was developed using i PrMgCl and odorless 1-dodecanthiol, n C12H25SH, under mild reaction conditions, during which in situ-generated C12H25SMgCl selectively reacted with carbonyl group of esters. variety aromatic aliphatic were readily converted up to 99% yield excellent functional tolerance. Furthermore, based on quantitative formation thioesters, we successfully applied our method a one-pot synthesis ketones aldehydes

Finely resolved fluorescent images can be generated from a non-fluorescent precursor polymer film via photolithography. The synthesis of the methyl methacrylate and t-BOC-protected quinizarin monomer shown in Figure is reported as method for subsequent deprotection generation patterned color images.

In the post-COVID-19 era, virology-related research, which not only depends on governments as its main source of funding but also requires international and interdisciplinary collaborations, is recognized an essential defense for sustainability. Few published studies have examined trend, certain viruses before mid-2010s. Moreover, it challenging to define generally accepted research fields due broad spectrum. Thus, time that we confront unprecedented pandemic understand status nationally...

Building a pattern detection model using deep learning algorithm for data collected from manufacturing sites is an effective way to perform decision-making and assess business feasibility enterprises, by providing the results implications of patterns analysis big occurring at sites. To identify threshold abnormal requires collaboration between analysts process experts, but it practically difficult time-consuming. This paper suggests how derive setting without manual labelling offers...

Many countries define policies to manage oceans and coastal areas in order utilize marine ecosystems strategically. When we reviewed the strategies of various relation ocean sustainability, found that biodiversity preservation is a key issue for related sustainable development. We investigated research trends collaboration status China, Japan South Korea regarding through analysis scientific articles using bibliometric analysis. The results showed collaborated most with other compared China...

Here, we describe an enantioselective intramolecular oxidative aminoacetoxylation reaction using a palladium catalyst and aryl-substituted internal alkene compound as the substrate under mild conditions in several hours. The triazole-oxazoline ligand was selected for asymmetric catalyst. A range of enantioenriched pyrrolidine-derived vicinal amino acetate compounds were synthesized, showing yields from 47% to 84%, diastereomer ratios 57:43 95:5, enantiomer excesses 67% 92%.

Objectives : Trend of R&D herbal medicine for dementia treatment was examined based on the quantitative information analysis establishing national strategy research with oriental medicine. Methods Definition made to clarify technology development treatment. Based initial keyword provided by experts in field, queries were compounded conduct search engines WoS and DWPI. The raw data (papers or patents) extracted from expert-review before objects determined. Then, accumulated analyzed terms...

We proposed the systematic monitoring process for identifying competitors' patents which competitors have currently been implemented. Two kinds of factors were considered to compare with similarities between a pair (2-dimensional hybrid similarity calculation method). One is technology-terms described in claim-part patent document; other technology classification patent. To verify this method, 4 cases legally argued past adopted and applied.

Infectious diseases have been continuously and increasingly threatening human health welfare due to a variety of factors such as globalisation, environmental, demographic changes, emerging pathogens. In order establish an interdisciplinary approach for coordinating R&D via funding, it is imperative discover research trends in the field. this paper, we apply machine learning methodologies network analyses understand how European Union (EU) United States (US) invested their funding...

In this paper, a computationally efficient stack-based iterative detection algorithm is proposed for V-BLAST systems. To minimize the receiver's efforts as much possible, scheme employs tree search complexity reduction and storage saving. After an M-ary structure by QR decomposition of channel matrix constructed, full depth divided into first remaining ones. At one, finds M candidate symbols. Based on these symbols, it iteratively searches symbols at second-to-last depth, until finding...

Time-frequency-selective, equivalently time-variant multipath, fading channels in orthogonal frequency division multiplexing (OFDM) systems introduce intercarrier interference (ICI), resulting severe performance degradation. To suppress the effect of ICI, several symbol detection methods have been proposed, all which are based on observation that most ICI's power is distributed near desired subcarrier. However, these usually ignore channel variation a OFDM block by fixing number considered...

The space-time block coding (STBC) and space-frequency (SFBC) are considered for of OFDM signals. A proper scheme selected based on estimated normalized delay spread Doppler spread. selection criterion derived empirically. It shown through computer simulations proposed switching improve bit error rate (BER) performance...

Abstract An aerated vessel with Simcar type surface aerator was studied to estimate its significant performance characteristics i.e., oxygen transfer rate, mixing time and power consumption.

We present a computationally efficient sequential detection scheme using modified Fano algorithm (MFA) for V-BLAST systems. The proposed consists of the following three steps: initialization, tree searching, and optimal selection. In first step, chooses several candidate symbols at level one. Based on these symbols, MFA then finds remaining transmitted from second in original structure. Finally, an symbol sequence is decided among most likely sequences searched previous step. Computer...

There have been many discussions on the globalisation of SMEs, but it is true that there not enough academic achievement after such study Born global (BG) ventures. The internationalisation SMEs (Small and Medium Enterprises) easy because they lack resources or capabilities compared to multinational corporations. This investigated role government in assisting SMEs. In particular, lacked ability acquire market-oriented information, so we’ve established scheme efficient information...
