Slipchip offers advantages such as high-throughout, low cost, and simple operation, and therefore, it is one of the technologies with the greatest potential for high-throughput, single-cell, and single-molecule analyses. Slipchip devices have achieved remarkable advances over the past decades, with its simplified molecular diagnostics gaining particular attention, especially during the COVID-19 pandemic and in various infectious diseases scenarios. Medical testing based on nucleic acid amplification in the Slipchip has become a promising alternative simple and rapid diagnostic tool in field situations. Herein, we present a comprehensive review of Slipchip device advances in molecular diagnostics, highlighting its use in digital recombinase polymerase amplification (RPA), loop-mediated isothermal amplification (LAMP), and polymerase chain reaction (PCR). Slipchip technology allows users to conduct reliable droplet transfers with high-throughput potential for single-cell and molecule analyses. This review explores the device’s versatility in miniaturized and rapid molecular diagnostics. A complete Slipchip device can be operated without special equipment or skilled handling, and provides high-throughput results in minimum settings. This review focuses on recent developments and Slipchip device challenges that need to be addressed for further advancements in microfluidics technology.

In the molecular cloud G33.92+0.11A, massive stars are forming sequentially in dense cores, probably due to interaction with accreted gas. Cold dense gas, which is likely the pristine gas of the cloud, is traced by DCN line and dust continuum emission. Clear chemical differences were observed in different source locations and for different velocity components in the same line of sight. Several distinct gas components coexist in the cloud: the pristine cold gas, the accreted dense gas, and warm turbulent gas, in addition to the star-forming dense clumps. Filaments of accreted gas occur in the northern part of the A1 and A5 clumps, and the velocity gradient along these features suggests that the gas is falling toward the cloud and may have triggered the most recent star formation. The large concentration of turbulent gas in the A2 clump seems to have formed mainly through disturbances from the outside.

Using ALMA observations of the 13CN and DCN lines in the massive star-forming region G33.92+0.11A, we investigate the CN/HCN abundance ratio, which serves as a tracer of photodissociation chemistry, over the whole observed region. Even considering the uncertainties in calculating the abundance ratio, we find high ratios (》1) in large parts of the source, especially in the outer regions of star-forming clumps A1, A2, and A5. Regions with high CN/HCN ratios coincide with the in infows of accreted gas suggested by Liu et al. (2015). We conclude that we found strong evidence for interaction between the dense gas clumps and the accreted ambient gas which may have sequentially triggered the star formation in these clumps.

The disadvantage of the current Red imported fire ants (RIFA) diagnostic is that it takes at least two days, because it is subjected to PCR amplification and DNA sequence identification process using an arthropod universal mitochondrial cytochrome oxidase I prime pair after genomic DNA extraction. In order to overcome this drawback, two RIFA specific genes were confirmed and used to develop techniques for identifying the species using various PCR methods. The conventional PCR method can be confirmed by the presence of amplified DNA, but additional time is required to confirm whether the PCR products are present or not. In contrast, SYBR green Real Time (RT) PCR or TaqMan probe RT PCR method has the advantage of confirming the results immediately after the reaction is completed. The new molecular diagnostic method has the advantage of shortening the time of two days, which is the biggest disadvantage of RIFA molecular diagnostic method, to 3 hours or less.

Recently, thanks to emerging ICT (Information and Communication Technology) such as IoT (Internet of Things), wireless telecommunication, and various sensor technologies, the concept of connected car has been highlighted in the automotive industry. In the connected car technology, one application is to diagnose and predict the car status in a real-time way based on gathered data. To this end, it is necessary to develop the diagnostics/prognostics algorithms for a specific part or component in a car. The results of diagnostics and prognostics could provide drivers with useful information used for advanced maintenance policy such as condition-based maintenance. In this study, we have reviewed the relevant previous research works before developing detailed algorithms.

The graphene oxides (GOs) were tested as a fluorescent quencher in the field of DNA-diagnostics. The various suspensions of GO nanoplates were prepared by changing the synthesis conditions. The suspensions were stable for at least 6 weeks by differing degrees of functionalization of various oxygen-containing groups of atoms. Depending on the properties of GO nanoplates, their fluorescent quenching abilities, which were determined by the amount of the tagged immobilized oligonucleotide, were also changed. GO suspension synthesized at 75 oC of reaction mixture showed the fluorescent quenching of 16.39 nmol/mg, which would be a potential substitution of molecular fluorescent quencher in test-systems for DNAdiagnostics.

We combine data from two all-sky surveys, the Swift/Burst Alert Telescope 22 Month Source Catalog and the AKARI Point Source Catalogue, in order to study the connection between the hard X-ray (> 10 keV) and infrared (IR) properties of local active galactic nuclei (AGN). We find two photometric diagnostics are useful for source classification: one is the X-ray luminosity vs. IR color diagram, in which type 1 radio-loud AGN are well isolated from other AGN. The second one uses the X-ray vs. IR color-color diagram as a redshift-independent indicator for identifying Compton-thick (CT) AGN. Importantly, CT AGN and starburst galaxies in composite systems can also be separated in this plane based upon their hard X-ray fluxes and dust temperatures. This diagram may be useful as a new indicator to classify objects in new surveys such as with WISE and NuSTAR.

  The high degree of viscosity and the non-Newtonian fluid dynamics characterizes the process inside a glass furnace. Because the temperature is fluctuating in very short time-intervals, it is hard to determine that the status of its fluctuation is stable

There are at least three effects of the non-thermal particle bombardment on the solar atmosphere: (1) non-thermal ionization and excitation; (2) proton-hydrogen charge exchange; (3) impact line polarization. Due to the non-thermal ionization and excitation effects of electron bombardments in flares, Hα line is widely broadened and shows a strong central reversal. Significant enhancements at the line wings of Lyα and Lyβ are also predicted. In the case of proton bombardment, less strong broadening and no large central reversal are expected. However, due to proton-hydrogen charge exchange, the enhancements at the red wings of Lyα and especially of Lyβ lines at the early impulsive phase of flares are significant. Electron beam can also in some cases generates visible and UV continuum emission in white-light flares. However, at the onset phase, a negative 'black' flare may appear in several seconds, due to the increase of the H- opacity. The impact polarization of atomic lines can provide complementary information on the energetic particles, the energy transport and deposit in the solar chromosphere. New results of spectropolarimetric analysis for the major flare on July 23, 2002 are also given in the paper.

당뇨병 환자의 혈당치 측정을 위하여 다층젤라틴 필름으로 만들어진 진단막을 제조하였다. 플라즈마와 혈액 속의 글루코우즈의 농도 변화에 따른 최대확산속도를 측정하였다. 여러 가지 온도에서 3일, 2주, 4주 보관후 온도가 글루코우즈의 확산속도에 미치는 영향을 조사하였다. 다층 젤리탄 진단막의 안정성을 상대습도 80%에서 측정하였다.

Non-LTE calculations, with the non-thermal ionization effects included, indicated that for electron bombardment, the Hα line is widely broadened and shows a strong central reversal. Significant enhancements at the line wings of Lyα and Lyβ are also predicted at the beginning of the impulsive phase of flares. For the proton bombardment, no strong broadening and no large central reversal are expected. However, due to proton-hydrogen charge exchange, the enhancements at the red wings of Lyα and Lyβ lines at the early impulsive phase of flares are significant. Our results show that the electron beam can also in some cases generate visible and UV continuum emission in white-light flares. However, at the onset phase, a negative flare may appear within several seconds, due to the increase of the H- opacity. Another spectroscopic signature of energetic particles, i.e. the impact polarization of atomic lines, is also mentioned.

대향타겟트형 스파터기에서 BaO-l2Fe 복합타겟트를 사용하고 50% O2+Ar 스파터가스를 사용한 반응성 프라즈마를 스펙트로스포프법으로 검진하였다. 프라즈마의 스펙트럼은 Ba, Ba+, Fe, FeO, Fe+, Ar, Ar+, O, O+의 피크로 이루어져 있었으며 타겟트로 부터 멀어짐에 따라 이온의 상대강도는 중성원소의 그것에 비하여 더 감소하였다.

This paper is a part of the series on positron annihilation spectroscopy of two-phase diffuse gas-and-dust aggregates, such as interstellar medium and the young remnants of type II supernovae. The results obtained from prior studies were applied here to detect the relationship between the processes of the annihilation of the K-shell electrons and incident positrons, and the effects of these processes on the optical spectra of their respective atoms. Particular attention was paid to the Doppler broadening of their optical lines. The relationship between the atomic mass of the elements and the Doppler broadening, ΔλD (Å), of their emission lines as produced in these processes was established. This relationship is also illustrated for isotope sets of light elements, namely 3 6 7 7 9 10 11 2 3 3 4 4 5 5 He, Li, Li, Be, Be, B, and B. A direct correlation between the γ-line luminosity ( Eγ =1.022 MeV) and D Δλ (Å) was proved virtually. Qualitative estimates of the structure of such lines depending on the positron velocity distribution function, f(E), were made. The results are presented in tabular form and can be used to set up the objectives of further studies on active galactic nuclei and young remnants of type II supernovae.

The study investigates the validity of ‘subjecthood diagnostics’ in Korean proposed in the previous studies. Based on the studies on subjecthood diagnostics in Korean Single Subject Constructions (non-MSCs) and Multiple Subject Constructions (MSCs), the role of two subjecthood diagnostics―Honorific Agreement (HA) and Plural Copying (PC)―in these two constructions are examined through an empirical syntactic experiment. Seventy Korean native speakers participated in the experiment using acceptability judgment task designed to probe their intuition. The results show (i) that in the Non-MSCs, Honorific Agreement (HA) reliably seems to choose the subject (i.e., the only Nom-marked NP), whereas Plural Copying (PC) does not seem to pick out the subject in a less consistent manner; and (ii) that in the MSCs, neither Honorific Agreement (HA) nor Plural Copying (PC) seems to be a reliable subjecthood diagnostic. Possible reasons for these results are discussed.
