We analyze one-loop vacuum stability, perturbativity, and phenomenological constraints on a complex singlet extension of the Standard Model (SM) scalar sector containing dark matter candidate. study stability considerations using gauge-invariant approach compare with conventional gauge-dependent procedure. show that, if new physics exists at TeV scale, analysis experimental from sector, electroweak precision data, LEP allow both Higgs-like in mass range allowed by latest results CMS ATLAS...
Abstract A method to directly collect negatively charged nucleic acids, such as DNA and RNA, in the biosamples simply by applying an electric field between sample collection buffer separated nanofilter membrane is proposed. The was made of low-stress silicon nitride with a thickness 100 nm, multiple pores were perforated highly arranged pattern using nanoimprint technology pore size 200 nm density 7.22 × 10 8 /cm 2 . electrophoretic transport hsa-mir-93-5p across confirmed pure microRNA...
Abstract Postsurgical intraocular lens (IOL) infection caused by pathogenic bacteria can result in blindness and often requires a secondary operation to replace the contaminated lens. The incorporation of an antibacterial property onto IOL surface prevent bacterial postoperative endophthalmitis. This study describes polymeric nanopillar array (NPA) integrated IOL, which captures eradicates rupturing membrane. is accomplished changing behavior elastic nanopillars using bending, restoration,...
High sulfur content polymers (HSCPs) are regarded as promising materials for infrared (IR) optics, especially the long-wave IR range, due to intrinsic properties of sulfur, but poor thermal stability HSCPs limits their reliable utilization in wider applications. We herein present a new HSCP, poly(sulfur-co-hexavinyl disiloxane) (pSHVDS), prepared directly from elemental through vapor chemical deposition (sCVD). By employing hexavinyl disiloxane (HVDS) comonomer with high functionality (f =...
Polyhydroxyalkanoates (PHAs) have gained much attention as a potential alternative to conventional plastic bone scaffolds due their biocompatibility and biodegradability, among diverse range of advantageous properties. However, the water resistance PHA creates an environment that can interfere with cell interactions. In this study, three-dimensional-printed scaffold was fabricated through fused deposition modeling printing considering physical properties PHA. The were then coated...
This paper proposes a new ringing-artifact reduction method for image resizing in block discrete cosine transform (DCT) domain. The proposed reduces ringing artifacts without further blurring, whereas previous approaches must find compromise between blurring and artifacts. consists of DCT-domain filtering image-domain post-processing, which ripples on smooth regions as well overshoot near strong edges. By generating mask map the regions, we combine ripple-reduced an overshoot-reduced...
Abstract Many electrochemical biosensors are developed and widely used for the detection of biological responses. However, there is a limitation like increasing surface area working electrode improvement sensitivity. Nanoimprint lithography (NIL) simple method that uses stamp UV or thermally curable resins fabricating nanopatterns nanostructures at low cost with high throughput resolution. Therefore, fabrication nanostructure on using nanoimprint can improve not only sensitivity biosensor to...
To achieve an effective surface-enhanced Raman scattering (SERS) sensor with periodically distributed “hot spots” on wafer-scale substrates, we propose a hybrid approach combining physical nano-imprint lithography and chemical deposition method to form silver microbead array. Nano-imprint (NIL) can lead mass-production high throughput, but is not appropriate for generating strong “hot-spots.” However, when apply electrochemical NIL substrate the reaction time was increased 45 s, periodical...
Surface-enhanced Raman spectroscopy (SERS) detection in microfluidics is an interesting topic because of its high sensitivity, miniaturization, and ability to perform online detection. However, the difficulties generating SERS-based microfluidic devices with uniform signal reproducibility sensitivity have hindered their widespread application. In addition, recyclability can contribute broad commercialization, but possible contamination area cumbersome cleaning procedures remain a challenge....
