| ○ | ○ | Article | Periodic Maxwell-Chern-Simons vortices with concentrating property | In order to study electrically and magnetically charged vortices in fractional quantum Hall effect and anyonic superconductivity, the Maxwell-Chern-Simons (MCS) model was introduced by Lee et al. (Phys Lett B 252:79-83, 1990) as a unified system of the classical Abelian-Higgs model (AH) and the Chern-Simons (CS) model. In this article, the first goal is to obtain the uniform (CS) limit result of (MCS) model with respect to the Chern-Simons parameter, without any restriction on either a particular class of solutions or the number of vortex points, as the Chern-Simons mass scale tends to infinity. The most important step for this purpose is to derive the relation between the Higgs field and the neutral scalar field. Our (CS) limit result also provides the critical clue to answer the open problems raised by Ricciardi and Tarantello (Comm Pure Appl Math 53:811-851, 2000) and Tarantello (Milan J Math 72:29-80, 2004), and we succeed to establish the existence of periodic Maxwell-Chern-Simons vortices satisfying the concentrating property of the density of superconductive electron pairs. Furthermore, we expect that the (CS) limit analysis in this paper would help to study the stability, multiplicity, and bubbling phenomena for solutions of the (MCS) model. | Ao, Weiwei; Kwon, Ohsang; Lee, Youngae | Wuhan Univ, Dept Math & Stat, Wuhan 430072, Peoples R China; Chungbuk Natl Univ, Dept Math, Chungdae Ro 1, Cheongju 362763, Chungbuk, South Korea; Kyungpook Natl Univ, Teachers Coll, Dept Math Educ, Daegu, South Korea | Lee, Youngae/GPG-2128-2022 | 56895823800; 57218663165; 58239646700 | wwao@whu.edu.cn;ohsangkwon@chungbuk.ac.kr;youngaelee@knu.ac.lcr; | MATHEMATISCHE ANNALEN | MATH ANN | 0025-5831 | 1432-1807 | 381 | 3-4 | SCIE | MATHEMATICS | 2021 | 1.334 | 26.9 | 0.45 | 2025-07-30 | 2 | 2 | 35B40; 35J20 | NONTOPOLOGICAL MULTIVORTEX SOLUTIONS; BLOW-UP SOLUTIONS; CONDENSATE SOLUTIONS; GINZBURG-LANDAU; HIGGS-MODEL; TOPOLOGICAL SOLUTIONS; BUBBLING SOLUTIONS; GLOBAL EXISTENCE; ASYMPTOTIC LIMIT; CAUCHY-PROBLEM | English | 2021 | 2021-12 | 10.1007/s00208-020-02057-7 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Enhanced photoluminescence characteristics and intrinsic ferromagnetism in Co-substituted CeO2 nanoparticles | The creation of oxide based magnetic materials has attracted a great deal of scientific attention, owing to their novel applications in optoelectronic, memory, and spintronic device applications. In this study, the authors report upon the structural, optical, and magnetic properties of Co-substituted CeO2 nanocrystals synthesized via the wet chemical precipitation method. The obtained nanoparticles show good crystallinity as well as an FCC structure with an Fm3m space group of host CeO2 lattice, as confirmed by an X-ray diffraction results. It is noted that Co substitution at low concentrations enhances the photoluminescence characteristics of CeO2 nano particles, while higher concentrations significantly reduce the intensity of PL emission, as revealed by PL studies. The estimated M H loops illustrate that pristine CeO2 shows a paramagnetic nature, while all Co-substituted samples were ferromagnetic in nature. Furthermore, magnetic parameters such as saturation magnetization (M-S) and residual magnetization (M-R) increased with the inclusion of Co content, reaching a maximum at 4 at% Co and quenching at 6 at% and 8 at% of Co-substitution. In particular, Ce1-xCoxO2 (x = 0.04) nanoparticles show better luminescence and magnetic characteristics than the remaining concentrations. | Poornaprakash, B.; Subramanyam, K.; Kumar, Mirgender; Kim, Y.

| ○ | ○ | Article | First-principles investigation of the physical properties of indium based fluoroperovskites InAF3 (A = Ca, Cd and Hg) | The theoretical study is performed to investigate the structural, elastic, electronic and optical properties of Indium based fluoroperovskites InAF(3) (A = Ca, Cd, and Hg) based on the Density Functional Theory (DFT) using the Full-Potential Linearized Augmented Plane Wave (FP-LAPW) method implemented in WIEN2K. Generalized Gradient Approximation (GGA) with Hubbard term (GGA + U) is employed for the incorporation of exchangecorrelation energy. The optimized lattice constants are found in the range of 4.51 angstrom to 4.69 angstrom. The calculated values of elastic constants show that compounds satisfy the stability criteria for a cubic system. It has also been observed that all the compounds are ductile and show anisotropic behavior. Calculated bandgaps of InCaF3 and InCdF3 are 3.66 eV and 3.29 eV, respectively, exhibiting direct band nature. The InHgF3 is found to be an indirect bandgap material having the value of 1.59 eV. The significance of states contributed by each element is inferred from the total and partial density of state plots. The optical characteristics are discussed and analyzed in a broad energy range (with specific range shown 0-30 eV) using important parameters such as optical conductivity and reflectivity, refractive index, extinction coefficient, and absorption coefficient. The results are communicated for the first time for understudy Indium based compounds. | Khan, Sajid; Ahmad, Rashid; Mehmood, Nasir; Hina, Faryal; Rehman, Alatf Ur; Zaman, Shams U.; Kim, H.

| ○ | ○ | Article | Mn and Al co-doped CdS:Cr nanoparticles for spintronic applications | Nowadays, diluted magnetic semiconductors with improved ferromagnetic feature is utterly seeking for use in modern spintronic applications.We describe the optical as well as magnetic properties of CdS, CdS:Cr, CdS:(Cr + Al), and CdS:(Cr + Mn) co-doped samples. The substitution of Cr dopant and co-dopant ions (Al and Mn) in the host sites were confirmed through structural analysis. Declining of energy band gap with the incorporation of Cr dopant and co-dopant ions (Al and Mn) into the CdS host lattice was estimated through optical studies. Roomtemperature magnetic hysteresis curves revealed that pure CdS exhibited paramagnetic nature due to its surface defects, whereas CdS:Cr, CdS:(Cr + Al), and CdS:(Cr + Mn) co-doped nanoparticles showed better ferromagnetic characteristics. Among all synthesized nanoparticles, CdS:(Cr + Al) semiconductor sample exhibited enhanced ferromagnetic nature and may benficial for spintronic applications. | Poornaprakash, B.; Subramanyam, K.; Cheruku, Rajesh; Kim, Y.

| ○ | ○ | Article | Thallium lead iodide (TlPbI3) single crystal inorganic perovskite: Electrical and optical characterization for gamma radiation detection | TlPbI3 has been suggested as a candidate semiconductor material for room temperature gamma ray and charged particle detection, motivated by its wide bandgap (2.17-2.3 eV), and high density (6.6 gm/cm(3)) required for low noise and high intrinsic detection efficiency. In this work, we studied the optical and electronic properties of Bridgeman-grown TlPbI3 single crystal using ultraviolet-visible-infrared absorption spectroscopy, low temper-ature cathodoluminescence, temperature dependent current-voltage measurements, and charge carriers' mobility-lifetime measurements. The fabricated Ag/TlPbI3/Ag device showed Ohmic behavior in temperatures ranging between-7 degrees C to 22 degrees C and exhibited high resistivity (similar to 2 x 10(11) Omega.cm at RT). Fermi level pinning at 0.72 eV above valence band minimum or below conduction band maximum was calculated from the temperature dependent resistivity measurement, and the 2.17 eV bandgap was determined from ultraviolet-visible-infrared absorption spectroscopy. The cathodoluminescence spectrum of TlPbI3 was resolved to two peaks at 1.45 eV and 1.48 eV indicating deep level traps. The mobility-lifetime product was estimated to be 3.43 x 10(-5) cm(2)/V and 2.29 x 10(-6) cm(2)/V for electrons and holes, respectively. Possible interpretations are presented suggesting the presence of vacancy type defects. Our results provide new essential information for developing such a new class of room temperature radiation detector material for a wide range of applications. | Hany, Ibrahim; Yang, Ge; Phan, Quoc Vuong; Kim, Hong Joo | North Carolina State Univ, Dept Nucl Engn, Raleigh, NC 27695 USA; Kyungpook Natl Univ, Dept Phys, Daegu 41566, South Korea | ; Yang, Ge/G-1354-2011; Kim, Hong Joo/AAE-1178-2022; Hany, Ibrahim/AAS-2210-2020 | 57210345895; 57203587369; 57202820686; 59051568100 | gyang9@ncsu.edu; | MATERIALS SCIENCE IN SEMICONDUCTOR PROCESSING | MAT SCI SEMICON PROC | 1369-8001 | 1873-4081 | 121 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2021 | 4.644 | 27.0 | 1.61 | 2025-07-30 | 17 | 25 | Perovskites; Radiation detector; Cathodoluminescence; UV-Vis-IR absorption spectroscopy | ELECTRONIC-STRUCTURE; GROWTH | Cathodoluminescence; Perovskites; Radiation detector; UV-Vis-IR absorption spectroscopy | Absorption spectroscopy; Carrier mobility; Cathodoluminescence; Charged particles; Chemical detection; Electric currents; Electronic properties; Energy gap; Gamma rays; Infrared absorption; Layered semiconductors; Light absorption; Perovskite; Semiconducting lead compounds; Single crystals; Temperature; Thallium compounds; Wide band gap semiconductors; Cathodoluminescence spectra; Charged particle detection; Current voltage measurement; Lifetime measurements; Mobility-lifetime products; Optical and electronic properties; Optical characterization; Temperature-dependent resistivity; Iodine compounds | English | 2021 | 2021-01 | 10.1016/j.mssp.2020.105392 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Unusual shift in the visible absorption spectrum of an active ctenophore photoprotein elucidated by time-dependent density functional theory | Active hydromedusan and ctenophore Ca2+-regulated photoproteins form complexes consisting of apoprotein and strongly non-covalently bound 2-hydroperoxycoelenterazine (an oxygenated intermediate of coelenterazine). Whereas the absorption maximum of hydromedusan photoproteins is at 460-470 nm, ctenophore photoproteins absorb at 437 nm. Finding out a physical reason for this blue shift is the main objective of this work, and, to achieve it, the whole structure of the protein-substrate complex was optimized using a linear scaling quantum-mechanical method. Electronic excitations pertinent to the spectra of the 2-hydroperoxy adduct of coelenterazine were simulated with time-dependent density functional theory. The dihedral angle of 60 degrees of the 6-(p-hydroxy)-phenyl group relative to the imidazopyrazinone core of 2-hydroperoxycoelenterazine molecule was found to be the key factor determining the absorption of ctenophore photoproteins at 437 nm. The residues relevant to binding of the substrate and its adopting the particular rotation were also identified. | Tomilin, Felix N.; Rogova, Anastasia V.; Burakova, Ludmila P.; Tchaikovskaya, Olga N.; Avramov, Pavel V.; Fedorov, Dmitri G.; Vysotski, Eugene S. | Fed Res Ctr Krasnoyarsk Sci Ctr SB RAS, Kirensky Inst Phys SB RAS, Akademgorodok 50-38, Krasnoyarsk 660036, Russia; Siberian Fed Univ, Svobodny 79 Pr, Krasnoyarsk 660041, Russia; Natl Res Tomsk State Univ, Lenin Ave 36, Tomsk 634050, Russia; Fed Res Ctr Krasnoyarsk Sci Ctr SB RAS, Photobiol Lab, Inst Biophys SB RAS, Akademgorodok 50-50, Krasnoyarsk 660036, Russia; Kyungpook Natl Univ, 80 Daehakro, Daegu 41566, South Korea; Natl Inst Adv Ind Sci & Technol, Res Ctr Computat Design Adv Funct Mat CD FMat, Cent 2,Umezono 1-1-1, Tsukuba, Ibaraki 3058568, Japan | Rogova, Anastasia/ADS-6671-2022; Tomilin, Felix/F-3763-2014; Burakova, Lyudmila/O-1262-2016; Vysotski, Eugene/I-1761-2013; Tchaikovskaya, Olga/O-6715-2014 | 6602246772; 57214097579; 24821226500; 6602638099; 7004322420; 56842563500; 6603777201 | d.g.fedorov@aist.go.jp;eugene.vysotski@gmail.com; | PHOTOCHEMICAL & PHOTOBIOLOGICAL SCIENCES | PHOTOCH PHOTOBIO SCI | 1474-905X | 1474-9092 | 20 | 4 | SCIE | BIOCHEMISTRY & MOLECULAR BIOLOGY;BIOPHYSICS;CHEMISTRY, PHYSICAL | 2021 | 4.328 | 27.1 | 0.5 | 2025-07-30 | 6 | 6 | LIGHT-SENSITIVE PHOTOPROTEIN; SEQUENCE-ANALYSIS; CA2+-BINDING LOOPS; CRYSTAL-STRUCTURE; SPATIAL STRUCTURE; BEROE ABYSSICOLA; BIOLUMINESCENCE; EXPRESSION; CLONING; OBELIN | Absorption spectra; Absorption spectroscopy; Blue shift; Dihedral angle; Substrates; Absorption maxima; Covalently bound; Electronic excitation; Linear scaling; Mechanical methods; Substrate complexes; Time dependent density functional theory; Visible absorption spectra; Density functional theory | English | 2021 | 2021-04 | 10.1007/s43630-021-00039-5 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | A robust scheme for unidirectional emission from a hybrid whispering gallery cavity system based on transformation optics | Using the transformation cavity, a gradient index cavity designed by transformation optics, we propose a hybrid resonator system to extract unidirectional narrow-beam emission from high-Q whispering gallery modes by embedding a transformation cavity inside a deformed uniform index cavity that exhibits unidirectional narrow-beam emission. For effective mode coupling between the transformation cavity and enclosing cavity, the embedded transformation cavity is designed to have bidirectional evanescent emission, which enables most of the emission from the transformation cavity to be laterally incident on the rim of the enclosing deformed cavity. Consequently, ultrahigh-Q resonances of this system can provide a sharp free-space light output, which is difficult to achieve by embedding a homogeneous disk cavity instead of the transformation cavity.

| ○ | ○ | Article | Birefringent whispering gallery cavities designed by linear transformation opticss | It was reported that whispering gallery cavities designed by conformal transformation optics can support high-Q resonant modes with emission directionality. Intrinsically, these cavities have gradient index profiles implementing conformal mappings in physical space. In this paper, using the linear coordinate transformation, we propose another design scheme of whispering gallery cavities with (piecewise-) homogeneous, anisotropic index profile. We numerically show that so-designed cavities are also able to support high-Q whispering gallery modes with directional far-field emission patterns. We verify such characteristics by using a phase space representation (called the Poincare Husimi function) of the intracavity wave function.

| ○ | ○ | Article | Emergence and dynamics of unconfined self-organised vortices in active magnetic roller liquids | Actively driven colloids demonstrate complex out-of-equilibrium dynamics often rivaling self-organized patterns and collective behavior observed in living systems. Recent studies revealed the emergence of steady macroscopic states with multiple interacting vortices in an unconfined environment that emerge from the coupling between microscale particle rotation and translation. Yet, insights into the microscopic behavior during the vortex emergence, growth, and formation of a multi-vortical state remain lacking. Here, we investigate in experiments and simulations how the microscale magnetic roller behavior leads to the emergence of seed vortices, their aggregation or annihilation, and the formation of stable large-scale vortical structures. We reveal that the coupling of roller-induced hydrodynamic flows guides the local self-densifications and self-organization of the micro-rollers into seed vortices. The resulting multi-vortical state is sensitive to the external magnetic field amplitude and allows tuning the rollers' number density in a vortex and its characteristic size. | Han, Koohee; Glatz, Andreas; Snezhko, Alexey | Argonne Natl Lab, Mat Sci Div, Lemont, IL 60439 USA; Kyungpook Natl Univ, Dept Chem Engn, Daegu, South Korea; Northern Illinois Univ, Dept Phys, De Kalb, IL 60115 USA | Glatz, Andreas/S-2121-2017; Snezhko, Alexey/S-3758-2017 | 57192061329; 7003760363; 55939956300 | snezhko@anl.gov; | SOFT MATTER | SOFT MATTER | 1744-683X | 1744-6848 | 17 | 46 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, MULTIDISCIPLINARY;POLYMER SCIENCE | 2021 | 4.046 | 27.2 | 0.35 | 2025-07-30 | 6 | 6 | DRIVEN; FLOCKS; STATES; ORDER | Magnetism; Vortex flow; Collective behaviour; Living systems; Macroscopic state; Micro-scale particles; Organized vortex; Out-of-equilibrium dynamics; Particle rotations; Particle translations; Self-organised; Self-organized patterns; article; destruction; hydrodynamics; magnetic field; plant seed; simulation; Rollers (machine components) | English | 2021 | 2021-12-01 | 10.1039/d1sm01086g | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Flat-top supercontinuum generation via Gaussian pulse shaping | We present the flat-top supercontinuum source with high repetition rate over a broad bandwidth. The flatness and high repetition rate are achieved by iterative optical line-by-line spectrum shaping on electro-optic optical frequency combs. By applying Gaussian apodized pulse train to a highly nonlinear medium with optimized Gaussian coefficient and nonlinear polarization rotation techniques, we implemented here a flat-top supercontinuum with a 47.7 nm bandwidth at 3 dB and 30 GHz repetition rate. The generation of high repetition rate supercontinuum sources with smooth and coherent spectrum is the critical challenging task for many applications such as optical communications and the optical arbitrary waveform generation. This work leads us to new possibilities for generating hundreds or thousands of flattened coherent optical carriers with a simple configuration.

| ○ | ○ | Article | Tensile elasticity of a freely jointed chain with reversible hinges | Many biopolymers exhibit reversible conformational transitions within the chain, which affect their bending stiffness and their response to a stretching force. For example, double stranded DNA may have denatured "bubbles" of unzipped single strands which open and close randomly. In other polymers, the transitions may be due to the reversible attachment and detachment of ligands on ligand-receptor complexes along the backbone. Semiflexible bundles under tension formed by the reversible attachment of cross-linkers, on a coarse-grained level, exhibit similar behaviour. The simplest theoretical model which captures what the above mentioned systems have in common is a freely jointed chain (FJC) with reversible hinges. Each hinge can be open, as in the usual FJC, or closed forcing the adjacent segments to align (stretch). In this article, we analyse it in the Gibbs ensemble. Remarkably, even though the usual FJC in the thermodynamic limit exhibits ensemble equivalence, the reversible FJC exhibits ensemble inequivalence. Even though a mean field treatment suggests a continuous phase transition to a fully hinged state at a certain force, the generating function method ("necklace model") shows that there is no phase transition. However, there is a crossover between the two states with clearly different responses. In the low force (linear response) regime, the reversible FJC has higher tensile compliance than its usual counterpart. In contrast, in the strong force regime, the tensile compliance of the reversible FJC is much lower than that of the usual FJC. | Noh, Geunho; Benetatos, Panayotis | Kyungpook Natl Univ, Dept Phys, 80 Daehakro, Daegu 41566, South Korea | ; Benetatos, Panayotis/AAT-5957-2021 | 57222632648; 6507575810 | pben@knu.ac.kr; | SOFT MATTER | SOFT MATTER | 1744-683X | 1744-6848 | 17 | 12 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, MULTIDISCIPLINARY;POLYMER SCIENCE | 2021 | 4.046 | 27.2 | 0.42 | 2025-07-30 | 9 | 9 | Biopolymers; DNA; Elasticity; Molecular Conformation; Thermodynamics; Biopolymers; Hinges; Ligands; biopolymer; DNA; Attachment and detachments; Conformational transitions; Continuous phase transitions; Ensemble inequivalence; Freely jointed chains; Ligand-receptor complex; Mean-field treatments; Theoretical modeling; conformation; elasticity; thermodynamics; Phase transitions | English | 2021 | 2021-03-28 | 10.1039/d1sm00053e | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Wide-viewing full-color depthmap computer-generated holograms | An efficient synthesis algorithm for wide-viewing full-color depthmap computer-generated holograms is proposed. We develop a precise computational algorithm integrating wave-optic geometry-mapping, color-matching, and noise-filtering to multiplex multiview elementary computer-generated holograms (CGHs) into a single high-definition CGH without three-dimensional perspective distortion or color dispersion. Computational parallelism is exploited to achieve significant computational efficiency improvement in the production through-put of full-color wide-viewing angle CGHs. The proposed algorithm is verified through the full-color binary hologram reconstruction experiments utilizing an off-axis R.G.B simultaneous illumination method, which suggests the feasibility of the full-color sub-wavelength binary spatial light modulator technology.

| ○ | Article | Incidence of and risk factors for short stature in children with chronic kidney disease: results from the KNOW-Ped CKD | Background: Preserving optimal growth has long been a significant concern for children with chronic kidney disease (CKD). We aimed to examine the incidence of and risk factors for short stature in Asian pediatric patients with CKD. Methods: We analyzed growth status by height, weight, and body mass index (BMI) standard deviation scores (SDSs) for 432 participants in the KoreaN cohort study for Outcome in patients With Pediatric Chronic Kidney Disease. Results: The median height, weight, and BMI SDSs were − 0.94 (interquartile range (IQR) − 1.95 to 0.05), − 0.58 (IQR − 1.46 to 0.48), and − 0.26 (IQR − 1.13 to 0.61), respectively. A high prevalence of short stature (101 of 432 patients, 23.4%) and underweight (61 of 432 patients, 14.1%) was observed. In multivariable logistic regression analysis, CKD stages 4 and 5 (adjusted odds ratio (aOR) 2.700, p = 0.001), onset before age 2 (aOR 2.928, p < 0.0001), underweight (aOR 2.353, p = 0.013), premature birth (aOR 3.484, p < 0.0001), LBW (aOR 3.496, p = 0.001), and low household income (aOR 1.935, p = 0.030) were independent risk factors associated with short stature in children with CKD. Conclusions: Children with CKD in Korea were shorter and had lower body weight and BMI than the general population. Short stature in children with CKD was most independently associated with low birth weight, followed by premature birth, onset before age 2, CKD stages 4 and 5, underweight, and low household income. Among these, underweight is the only modifiable factor. Therefore, we suggest children with CKD should be carefully monitored for weight, nutritional status, and body composition to achieve optimal growth.
