Using fluorescence fluctuation spectroscopy to quantify molecular dynamics within cells

FEBS Open Bio, EarlyView.
Microscopy techniques like fluorescence correlation spectroscopy (FCS) and number and brightness analysis (N&B) allow to quantify concentrations, diffusion rates, and oligomerization of fluorescently labeled molecules in the living cell. In this protocol the principles of how to set up these types of experiments are described including calibration ...

Efficiency Without Security Trade-off: Statistically Validated Cryptographic Hash Selection for Ethereum Fraud Detection

Journal of Applied Informatics and Computing
Cryptographic hash functions form the preprocessing layer of Ethereum fraud detection pipelines, yet prior research evaluated hash performance and fraud detection as separate concerns, leaving practitioners without evidence-based guidance for selecting ...

A New Strategy for Creating Quantum Light Emitters Via Post‐Growth Hydrogen‐Ion Irradiation of III‐V Nanowires

Advanced Functional Materials, EarlyView.
A post‐growth method is demonstrated to realize energy‐tunable quantum emitters in GaAs/GaAsN/GaAs core–multishell nanowires on a Si substrate. By combining the N‐induced bandgap reduction with H‐ion irradiation, the GaAsN potential landscape is engineered, enabling isolated, narrow emission lines that function as single‐photon sources with g(2)(0) ∼ 0.

Performance Analysis Cryptography Using AES-128 and Key Encryption Based on MD5

Jurnal Masyarakat Informatika
The rampant misuse of data theft has created data security techniques in cryptography. Cryptography has several algorithms that are very strong and difficult to crack, including the AES (Advanced Encryption Standard) algorithm consisting of 128 bits, 192

GeS as an Emerging OTS Material: Atomic Structure and Modeling of ON/OFF Switching

Advanced Functional Materials, EarlyView.
The structural puzzle of glassy GeS, an advanced memory‐selector material, has finally been disentangled, revealing a patchwork of mixed tetrahedral and trigonal species. Under a high electric field, over‐ and under‐coordinated Ge and S defects, together with three‐membered rings, form an interconnected network associated with localized and extended ...

Keyed Hash Function Using Hyper Chaotic System With Time-Varying Parameters Perturbation

IEEE Access, 2019
Secure hash function plays an important role in cryptography. This paper constructs a hash algorithm using the hyperchaotic Lorenz system, which serves as a sponge function to absorb input message via multiple parameters time-varying perturbation. First,

Wet-snow avalanche interaction with a deflecting dam: field observations and numerical simulations in a case study [PDF]

Natural Hazards and Earth System Sciences, 2012
In avalanche-prone areas, deflecting dams are widely used to divert avalanches away from endangered objects. In recent years, their effectiveness has been questioned when several large and multiple avalanches have overrun such dams.
