Abstract
Probing the diffusion of molecules has become a routine measurement across the life sciences, chemistry and physics. It provides valuable insights into reaction dynamics, oligomerisation, molecular (re-)organisation or cellular heterogeneities. Fluorescence correlation spectroscopy (FCS) is one of the widely applied techniques to determine diffusion dynamics in two and three dimensions. This technique relies on the temporal autocorrelation of intensity fluctuations but recording these fluctuations has thus far been limited by the detection electronics, which could not efficiently and accurately time-tag photons at high count rates. This has until now restricted the range of measurable dye concentrations, as well as the data quality of the FCS recordings, especially in combination with super-resolution stimulated emission depletion (STED) nanoscopy.
Here, we investigate the applicability and reliability of (STED-)FCS at high photon count rates (average intensities of more than 1 MHz) using novel detection equipment, namely hybrid detectors and real-time gigahertz sampling of the photon streams implemented on a commercial microscope. By measuring the diffusion of fluorophores in solution and cytoplasm of live cells, as well as in model and cellular membranes, we show that accurate diffusion and concentration measurements are possible in these previously inaccessible high photon count regimes. Specifically, it offers much greater flexibility of experiments with biological samples with highly variable intensity, e.g. due to a wide range of expression levels of fluorescent proteins. In this context, we highlight the independence of diffusion properties of cytosolic GFP in a concentration range of approx. 0.01–1 µm. We further show that higher photon count rates also allow for much shorter acquisition times, and improved data quality. Finally, this approach also pronouncedly increases the robustness of challenging live cell STED-FCS measurements of nanoscale diffusion dynamics, which we testify by confirming a free diffusion pattern for a fluorescent lipid analogue on the apical membrane of adherent cells.

Abstract
Detailed investigations of Ni substituted Fe0.994Ni0.007Te0.66Se0.34 and unsubstituted Fe0.99Te0.66Se0.34 crystals were performed at ambient pressure and under hydrostatic pressure in order to understand the complex relationship between structure, magnetism, and superconductivity in iron selenides. The aim of the investigations was to determine the structural and superconducting state properties and study their evolution under pressure, up to 11 kbar. A comparison of Fe0.99Te0.66Se0.34, a material with much less developed phase separation, with FeTe0.5Se0.5, a material exhibiting pronounced nanoscale phase separation, was also performed. Under ambient pressure, a weakening of superconducting state properties was observed in the Fe0.994Ni0.007Te0.66Se0.34 crystal, with disorder introduced by Ni substitution, as compared with those in Fe0.99Te0.66Se0.34. For Fe0.994Ni0.007Te0.66Se0.34, the x-ray diffraction studies have revealed a degradation of crystal quality under applied elevated pressure. Superconducting state properties of the single phase Fe0.99Te0.66Se0.34 crystal, such as upper and lower critical fields, were found to be poorer, at both ambient and hydrostatic pressure, than those observed for FeTe0.5Se0.5 crystals exhibiting pronounced nanoscale phase separation. Comprehensive studies of the impact of pressure on crystal structure and on superconducting state properties confirm that enhancement of superconductivity correlates with the appearance of mosaicity under pressure. The above observation leads to the expectation of a pressure-induced increase in inhomogeneity, leading to the enhancement of superconducting properties in other sulpho-iron seleno-tellurides of anti-PbO-type structure.

Abstract
Galactic Cosmic ray (CR) origin is still a mystery. Measuring the knees of the CR spectra for individual species is a very important approach to solve the problem. ARGO-YBJ and LHAASO-WFCTA[1] combined experiment made the first step by measuring the spectrum of hydrogen plus helium nuclei and finding the knee around 0.7 PeV[2]. A significant boost is expected by using LHAASO experiment[3] to measure the spectra and their knees for pure proton and other species in few years. The key is to separate the specific species from all CR samples. In this paper, a multi variate analysis (MVA) approach for the CR composition analysis in LHAASO experiment is discussed. Preliminary results of the analysis and expectations are presented.
Hyperon Structure and CP tests at BESIII
Authors: Adlarson Patrik 
Published: January 2020

Abstract
Hyperons are a powerful diagnostic tool that can shed light on some of the most intriguing questions in contemporary physics. Electromagnetic form factors (EMFFs) are currently the best way to study hyperon structure. In the time-like region the EMFFs can be complex with a relative phase. A non-zero phase polarizes the final state even when the initial state is unpolarized. A dedicated data sample collected by the BESIII experiment allowed for a first complete reconstruction of Λ in the time-like region. The ratio, R and relative phase between the electric and magnetic form factor, ΔΦ are measured to be 0.96±0.14(stat)±0.002(syst) and 37°±12°(stat)±6°(syst), respectively. In addition, the BESIII experiment has collected the world’s largest J/ψ data sample. Due to symmetric excellent detector conditions and low hadronic background, the experiment offers a clean environment for CP-violation tests using

Abstract
Marine plastic debris floating on the ocean surface is a major environmental problem. However, its distribution in the ocean is poorly mapped, and most of the plastic waste estimated to have entered the ocean from land is unaccounted for. Better understanding of how plastic debris is transported from coastal and marine sources is crucial to quantify and close the global inventory of marine plastics, which in turn represents critical information for mitigation or policy strategies. At the same time, plastic is a unique tracer that provides an opportunity to learn more about the physics and dynamics of our ocean across multiple scales, from the Ekman convergence in basin-scale gyres to individual waves in the surfzone. In this review, we comprehensively discuss what is known about the different processes that govern the transport of floating marine plastic debris in both the open ocean and the coastal zones, based on the published literature and referring to insights from neighbouring fields such as oil spill dispersion, marine safety recovery, plankton connectivity, and others. We discuss how measurements of marine plastics (both in situ and in the laboratory), remote sensing, and numerical simulations can elucidate these processes and their interactions across spatio-temporal scales.

Published: January 2020

Abstract
Problems encountered in traditional fish smoking was the inconsistency in the quality of the smoked fish produced, and so making the product provided less quality assurance to consumers. The type of fire-wood used as smoke fuel was also uncertain because it depended on the availability of the wood surrounding the smoking activity area. The aim of the research was to describe the method of traditional fish smoking and to determine the best typical wood used to produce smoked fish in the Province of Riau, Indonesia. The experimental method was used to examine the use of different kinds of fire-wood as the smoke source for selais catfish (Cryptopterus bicirchis) smoking. Several fire-woods used were kandis (Garcinia xanthochymus), laban (Vitex pinnata), ubar (Eugenia sp.) and timah-timah (Elaeocarpaecae sp.). The result showed that the catfish smoking in the province was applying direct hot smoking method. Smoked catfish produced was showing somewhat blackish brown, shiny, dry and clay textured, and weight reduction up to 25% from initial weight. The best wood used as smoke source was ubar wood, but not significantly different to laban wood. The best smoked fish produced was containing moisture, total phenolic and acid compound at 11.26%, 0.745%, and 0.92%, respectively.

Published: January 2020

Abstract
In heat stress conditions, E. coli will produce EF-Tu protein abundantly under the regulation of str promoter. The str promoter from E. coli is known to have sequences that are recognized by two sigma factors (σ70 and σS). The aim of this research was to isolate and characterize str promoter from E. coli DH5a using reporter gene AmilCP. The str promoter from E. coli DH5α (289 bp) had been isolated by Colony PCR using specific primers. Bioinformatics analysis of str promoter showed high conserved areas (100%) for some kinds of E. coli strains. The str promoter was constructed in pSB1C3 vector by modifying OEPC to regulate reporter gene AmilCP. Qualitatively, the ability of str promoter constructs in regulating AmilCP gene was observed as purple-blue colonies of E. coli. Quantitative analysis was performed by measuring cell extract of E. coli at a wavelength of 588 nm after treated at different temperatures (4, 24, 37, 45, 50, 55 and 60 °C) for 1 hour. The ability of str promo ter to express reporter gene AmilCP was compared to one powerful promoter which is the lacUV5 promoter. The results show that both promoters are functional promoters and can be induced by temperature (50 °C).
