Structural Design Scheme and Performance Analysis of Urban Rail Transit No.14 Turnout

open access: yesChengshi guidao jiaotong yanjiu
[Objective] Existing urban rail transit turnouts suffer from low lateral crossing speed, which adversely affects turn-back capacity. To enable 8-car A-type metro trains to achieve a capacity of 30 pairs per hour in the long term, it is necessary to ...

Machine Learning‐Supported Analysis for Predicting and Visualizing Nonlinear Relationships Between Material Properties in Electroplated Chromium Layers

open access: yesAdvanced Engineering Materials, EarlyView.
This study applies machine learning regression to predict chromium layer thickness in decorative trivalent chromium electroplating, using 441 experiments from laboratory‐scale (1L) and pilot‐scale (14L) setups. Tree‐based models, particularly CatBoost, outperformed linear regression by capturing nonlinear parameter interactions (R2$R^2$ up to 0.77 ...

Election turnout in authoritarian regimes

open access: yes, 2020
What explains election turnout in authoritarian regimes? Despite the significant energy, resources, and time ruling parties devote to improving the participation rates of citizens, there exists extraordinary variation both within and across authoritarian

Continuously Welded Rail Design for Overtaking Lines Added at Existing Elevated Metro Stations

open access: yesChengshi guidao jiaotong yanjiu
ObjectiveTo control the variations of track/bridge forces and displacements induced by adding overtaking lines at existing elevated metro stations, it is necessary to carry out comparative research on different layout schemes of CWR (continuously welded ...

The Democratic Turnout ‘Problem’

open access: yesPolitical Studies, 2011
A number of authors, including Lijphart, Hill and Engelen, have recently advocated compulsory voting. While numerous justifications can be given for such measures, it is often said that they are necessary to realise democracy fully, for instance ensuring that everyone casts one vote (no more and no less).

On the Effect of Creep on Local Lattice Orientation in Single‐Crystal Ni‐Based Superalloy Microstructures

open access: yesAdvanced Engineering Materials, EarlyView.
During creep of a single‐crystal Ni‐based superalloy, the overall crystal orientation is observed to remain constant while the microstructure evolves. Despite the lack of macroscopic rotation, small (<1°) rotations are observed on the submicron size scale and are accommodated by counteracting rotations over the scale of several micrometers.

Stretching the Printability Metric in Direct‐Ink Writing with Highly Extensible Yield‐Stress Fluids

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces “drawability” as a new metric for assessing printability in direct‐ink writing, focusing on gap‐spanning performance and speed robustness. By designing yield‐stress fluids with high extensibility, we demonstrate that extensional strain‐to‐break significantly enhances printability.

Omnipolar Magnetic Field Detection by Superlattice‐Based Hall Sensor

open access: yesAdvanced Functional Materials, EarlyView.
Magnetic‐field‐induced electronic switching is demonstrated in unit‐cell‐engineered La0.7Sr0.3MnO3–BiFeO3 superlattices. Distinct substrate terminations modify magnetic and transport properties. Hall resistance measurements show omnipolar, hysteretic anomalous Hall switching above the Curie temperature, arising from Fe─Mn interfacial exchange, enabling

The vertical mobility of the first tarsometatarsal joint during demi-plié with forced turnout in ballet dancers

open access: yesScientific Reports
The forced turnout has a perceived risk of development of hallux valgus (HV) in ballet dancers. We determined how the forced turnout affects the sagittal mobility of the first tarsometatarsal (TMT) joint, which is one of the pathogenic factors of HV ...

Why Did Voter Turnout in the Czech General Elections Change between 1996 and 2010?

open access: yesSociologický Časopis, 2011
The aim of this study is to explain why turnout in Czech general elections exhibited considerable variation between 1996 and 2010. Using valence theory this article explores the differential turnout in terms of the expected benefits of voting for a party
