Data Encryption in HDFS

open access: yes, 2023
Hadoop’s Hadoop Distributed File System (HDFS) faces security challenges such as internode communication vulnerabilities, replication storage mode vulnerabilities, and user access monitoring. Traditional encryption techniques can increase data size and slow down performance.

HDF: Introduction and Motivation

open access: yes, 1997
Although it is just over a year since the data was made public, the HDF exposure has stimulated considerable progress towards our understanding of the faint galaxy population. I present a brief personal account of the history of faint galaxy studies culminating in the HDF, and describe what I consider to be the main highlights thus far from this ...

Circulant Matrix‐Based Box–Behnken Designs With Economic Run Sizes

open access: yesQuality and Reliability Engineering International, Volume 42, Issue 6, Page 3326-3334, October 2026.
ABSTRACT We introduce Circulant Matrix‐Based Box–Behnken Designs (CBBDs), a new class of three‐level, second‐order response surface designs constructed using circulant matrix structures. These designs satisfy an enhanced orthogonal minimally aliased (OMA∗${\rm OMA}^*$) property: they retain the classical OMA property—where main effects are orthogonal ...

Discovery and Engineering of a Rat Endogenous Retrovirus Reverse Transcriptase for Efficient Prime Editing

open access: yesAdvanced Science, Volume 13, Issue 49, 3 September 2026.
We screened 558 reverse transcriptases and engineered an optimized rat endogenous retrovirus‐derived variant, enRERV‐RT, via structure‐guided engineering and deep mutational scanning. This enhanced prime editor, based on the engineered RT, outperforms conventional M‐MLV‐RT systems across plant and animal cells, particularly at hard‐to‐edit loci ...

Electrical‐Stimulation Hydrogel Electronic Skin for Sustainable Hybrid Biomechanical–Electromagnetic Energy Harvesting and Accelerating Wound Healing

open access: yesAdvanced Science, Volume 13, Issue 49, 3 September 2026.
A hybrid biomechanical–electromagnetic energy‐harvesting e‐skin is developed using a gelatin‐based outer matrix with a zwitterionic conductive inner layer. The e‐skin autonomously generates stable electrical stimulation from daily body motion and ambient electronics, enabling significantly enhanced wound healing bothin vitro and in vivo.

Comparison of biomarkers in children on high-flux HD and HDF.

open access: yes, 2018
(A) Markers of oxidative stress (ox-LDL, AGEs) were significantly reduced in addition to improvement in total antioxidant capacity, however nitrosative stress (nitrotyrosine) was not changed on HDF compared to HD. (B) Markers of inflammation (ß2M, hsCRP)

Sporadic Retinal Astrocytic Hamartoma Mimicking Retinoblastoma in a Child: A Case Report and Literature Review

open access: yesClinical Case Reports, Volume 14, Issue 9, September 2026.
ABSTRACT Retinal astrocytichamartoma (RAH) is a rare benign glial neoplasm most commonly associated with tuberous sclerosis complex (TSC). Sporadic cases, occurring in the absence of systemic phakomatosis, are uncommon and may closely mimic retinoblastoma, particularly when presenting with a calcified intraocular mass, creating a diagnostic challenge ...

Effect of inhibition of Akt, ERK, or JNK on LLLT-induced HDF proliferation.

open access: yes, 2017
(A) HDF proliferation was measured by the MTS assay after pretreatment with the inhibitor of Akt and subsequent LLLT irradiation (1.0 J/cm2). (B) HDF proliferation assay after pretreatment with the inhibitor of ERK and subsequent LLLT irradiation (1.0 J ...
