New technique illuminates DNA helix
DNA螺旋 细胞 运动蛋白
2023/5/23
Cornell researchers have identified a new way to measure DNA torsional stiffness – how much resistance the helix offers when twisted – information that can potentially shed light on how cells work.
Helix: A Scalable and Fair Consensus Algorithm Resistant to Ordering Manipulation
Blockchain Consensus protocol Byzantine agreement
2018/11/14
We present Helix, a Byzantine fault tolerant and scalable consensus algorithm for fair ordering of transactions among nodes in a distributed network. In Helix, one among the network nodes proposes a p...

2014/10/9
The DNA of every organism on Earth is a right-handed double helix, but why that would be has puzzled scientists since not long after Francis Crick and James Watson announced the discovery of DNA's dou...
Correlated Local Bending of a DNA Double Helix and Its Effect on DNA Flexibility in the Sub-Persistence-Length Regime
Correlated Local Bending a DNA Double Helix Effect on DNA Flexibility Sub-Persistence-Length Regime
2014/9/24
Mechanical characteristics of DNA in the sub-persistence-length (lP ≈150 base pairs) regime are vital to many of its biological functions but not well understood. Recent experimental studies in this r...
f-Eikonal helix submanifolds and f-Eikonal helix curves
Helix submanifold Eikonal function Helix line
2012/6/15
Let M{\subset}\mathbb{R}^{n} be a Riemannian helix submanifold with respect to the unit direction d{\in}\mathbb{R}^{n} and f:M{\to}\mathbb{R} be a eikonal function. We say that M is a f-eikonal helix ...
We characterize helix surfaces in the Berger sphere. In particular, we prove that, locally, a helix surface is invariant by the action of a 1-parameter group of isometries of the ambient space.
Construction of Chiral Metamaterial with a Helix Array
metamaterial helix chiral negative refractive index
2011/8/11
Abstract: Here we report the designing of chiral metamaterial with metallic helix array. The effective electric and magnetic dipoles, which originate from the induced surface electric current upon ill...
A Case Report of Bilateral Brodie Bite in Early Mixed Dentition Using Bonded Constriction Quad-helix Appliance
Brodie bite Early treatment Angle Class II malocclusion
2011/6/10
Brodie bite is a comparatively rare type of malocclusion found in primary and mixed dentition. It not only adversely affects chewing and muscle functions, but also impairs normal growth and developmen...
The Triple Helix, Quadruple Helix, . . ., and an N-tuple of Helices: Explanatory Models for Analyzing the Knowledge-based Economy?
triple helix N-tuple helices innovation system overlay model measurement
2010/12/28
Using the Triple Helix model of university-industry-government relations, one can measure the extent to which innovation has become systemic instead of assuming the existence of national (or regional)...
Nonlinear Localized Excitations in Helix Macromolecules
Pattern Formation and Solitons (nlin.PS)
2010/11/10
Physico-mechanical properties of polymers in solid state, in particular conditions of their structural transformations, are substantially defined by existence and mobility of elementary nonlinear exci...

The Triple Helix model of university-industry-government relations can be generalized from a neo-institutional model of networks to a neo-evolutionary model of how three selection environments operate...
Knowledge-Based Innovation Systems and the Model of a Triple Helix of University-Industry-Government Relations
Triple Helix University-Industry-Government Relations
2010/4/1
The (neo-)evolutionary model of a Triple Helix of University-Industry-Government Relations focuses on the overlay of expectations, communications, and interactions that potentially feed back on the in...
穿衣服的小蜗牛——Helix椅
Helix椅 小蜗牛
2009/9/10
Helix椅由南斯拉夫设计师Karmelina Martina于今年为意大利Moroso公司设计，并展出于本届米兰国际家具展。关于这件作品，设计师Martina有一个非常有趣的故事：Helix本是一只小蜗牛，有一天她厌倦了日复一日地生活在一成不变的厨房里，于是她背着行囊，带着一颗探索未知世界的心开始远行。Helix把太阳和月亮当作她的指南针，有一天她走到了一个森林里，但在继续前行时被困在了两棵树...
The Role of Knowledge Flow in the Thai GUIN Version of the Triple Helix Model

2009/7/16
The "triple helix" model is considered as being a spiral model of innovation contributing to the country and regional improvement by fostering interactions between academic, industry and government. T...
DNA may contain the blueprint for life but it takes proteins to read the plan and build an organism. The mechanism of this vital biological process has remained a mystery but now researchers in France...
