Secondary Clustering Recommendation Algorithm Based on Information Entropy [PDF]

Jisuanji gongcheng, 2016
The accuracy of final recommendation results is always affected by less active evaluation information of webpage texts which comes from users.Therefore,a secondary clustering recommendation algorithm based on information entropy is proposed.By extracting

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

FEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

Boolean-chaos-based physical random number generator

Tongxin xuebao, 2019
A novel method for generating physical random numbers using Boolean-chaos as the entropy source was proposed.An autonomous Boolean network (ABN) without self-feedback was constructed by using two-input logic gates,and its dynamic characteristics were ...

Numerical investigation of combined buoyancy-thermocapillary convection and entropy generation in 3D cavity filled with Al2O3 nanofluid

Alexandria Engineering Journal, 2017
Heat transfer, fluid flow and entropy generation due to combined buoyancy and thermocapillary forces in a 3D differentially heated enclosure containing Al2O3 nanofluid are carried out for different Marangoni numbers and different nanoparticles ...

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

FEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Function‐driven design of a surrogate interleukin‐2 receptor ligand

FEBS Letters, EarlyView.
Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in

E-BOOT: Preventing Boot-Time Entropy Starvation in Cloud Systems

IEEE Access, 2020
Due to the impracticability of generating true randomness by running deterministic algorithms in computers, boot-loaders and operating systems undergo the lack of enough supplies of entropy at boot-time.

Extrapolation estimates for entropy numbers

Journal of Functional Analysis, 2012
Let \(\Theta \subseteq [0,1]\) be an interval, let \(Y_0,Y_1\) be Banach spaces and let \(\{ Y_\eta \}_{\eta \in \Theta}\) be an ordered family of Banach spaces, i.e., \(Y_0 \hookrightarrow Y_\theta \hookrightarrow Y_\eta \hookrightarrow Y_1\) for any \(\theta \leq \eta\) with \(\theta, \eta \in \Theta\).

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

FEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
