Sanctuary of Eneolithic and Bronze Age in Western Siberia, as a source of astronomical knowledge and cosmological ideas in antiquity [PDF]

open access: yesArchaeoastronomy and Ancient Technologies, 2014
In article are considered the revealed astronomical knowledge and cosmological representations of the ancient population of the given territory on the basis of materials of excavation sanctuaries of Eneolit (Savin 1, Slobodchiki 1, Velizhany 2) and of ...

Making a case for interactive texts in language learning and teaching [PDF]

open access: yes, 2004
Hypertext has become a common reference point for CALL applications and hyperfiction is on the verge of becoming one too, it might be useful to briefly point out some of the major critical aspects of our current understanding of those ...

Holographic two-point functions for 4d log-gravity [PDF]

open access: yes, 2012
We compute holographic one- and two-point functions of critical higher-curvature gravity in four dimensions. The two most important operators are the stress tensor and its logarithmic partner, sourced by ordinary massless and by logarithmic non ...

Research on calculation of machine-tool settings and flank modification for spiral bevel gear by duplex spread blade method based on 4-axis CNC milling machine

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2020
A method is proposed to manufacture spiral bevel gear by duplex spread blade method based on 4-axis CNC milling machine. Firstly, the geometry parameters and machine-tool settings are comprehensively considered. To meet with the tooth taper, a new way is

The effect of a reference point in task difficulty: How does a task that becomes irrelevant affect effort, feelings and perceptions

open access: yesJudgment and Decision Making, 2022
We examine the effect of an irrelevant task that may become a reference point on subjects’ effort, feelings and perceptions. All subjects complete up to 25 tasks and are paid $0.10 per task solved correctly.

3D Point Cloud Denoising via Deep Neural Network based Local Surface Estimation

open access: yes, 2019
We present a neural-network-based architecture for 3D point cloud denoising called neural projection denoising (NPD). In our previous work, we proposed a two-stage denoising algorithm, which first estimates reference planes and follows by projecting ...

On running couplings in gauge theories from type-IIB supergravity [PDF]

open access: yes, 1999
We construct an explicit solution of type-IIB supergravity describing the strong coupling regime of a non-supersymmetric gauge theory. The latter has a running coupling with an ultraviolet stable fixed point corresponding to the N=4 SU(N) super-Yang ...

Reference Point Hyperplane Trees [PDF]

open access: yes, 2016
We make the simple observation that, the deeper a data item is within the tree, the higher the probability of that item being excluded from a search. Assuming a fixed and independent probability p of any subtree being excluded at query time, the probability of an individual data item being accessed is (1-p)d for a node at depth d.

A 65-nm CMOS Temperature-Compensated Mobility-Based Frequency reference for wireless sensor networks [PDF]

open access: yes, 2010
For the first time, a temperature-compensated CMOS frequency reference based on the electron mobility in a MOS transistor is presented. Over the temperature range from -55°C to 125 °C, its frequency spread is less than ±0.5% after a two-point trim and ...

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...
