DES Y3 + KiDS-1000: Consistent cosmology combining cosmic shear surveys Open
We present a joint cosmic shear analysis of the Dark Energy Survey (DES Y3) and the Kilo-Degree Survey (KiDS-1000) in a collaborative effort between the two survey teams. We find consistent cosmological parameter constraints between DES Y3…

The Mediating Effect of Herd Behavior and Brand Attitude towards the Impact of Spokesman Credibility, Source Fit, and Online Word-of-Mouth on Purchase Intention Open
Product endorsement has become a common marketing method. Many companies hire a famous person to act as the spokesman for the product and brand. They want to use the celebrity’s fame and attractiveness to promote their products and brands.…

SDSS-IV MaNGA: Unveiling Galaxy Interaction by Merger Stages with Machine Learning Open
We use machine-learning techniques to classify galaxy merger stages, which can unveil physical processes that drive the star formation and active galactic nucleus (AGN) activities during galaxy interaction. The sample contains 4690 galaxie…

KiDS-1000 catalogue: Redshift distributions and their calibration Open
We present redshift distribution estimates of galaxies selected from the fourth data release of the Kilo-Degree Survey over an area of ∼1000 deg 2 (KiDS-1000). These redshift distributions represent one of the crucial ingredients for weak …

AM PWM Driving Circuit for Mini-LED Backlight in Liquid Crystal Displays Open
This work proposes a mini-LED driving circuit that adopts the pulse-width modulation (PWM) driving method for use in a liquid-crystal display (LCD) backlight. The proposed circuit can compensate for the threshold voltage () variation in a …

KiDS-1000 cosmology: Cosmic shear constraints and comparison between two point statistics Open
We present cosmological constraints from a cosmic shear analysis of the fourth data release of the Kilo-Degree Survey (KiDS-1000), which doubles the survey area with nine-band optical and near-infrared photometry with respect to previous K…

KiDS+VIKING-450 and DES-Y1 combined: Mitigating baryon feedback uncertainty with COSEBIs Open
We present cosmological constraints from a joint cosmic shear analysis of the Kilo-Degree Survey (KV450) and the Dark Energy Survey (DES-Y1), which were conducted using Complete Orthogonal Sets of E / B -Integrals (COSEBIs). With COSEBIs, …

Validation of Approximate Likelihood and Emulator Models for Computationally Intensive Simulations Open
Complex phenomena in engineering and the sciences are often modeled with computationally intensive feed-forward simulations for which a tractable analytic likelihood does not exist. In these cases, it is sometimes necessary to estimate an …

The Percussive Character and the Lyrical Quality in Bartók’s Piano Music Open
The purpose of this study is to explore the percussive character and the lyrical quality in Bartók’s piano works. Bartók realized the nature of the piano as a percussion instrument. He used this idea in his piano works, and through differe…

Quantifying systematics from the shear inversion on weak-lensing peak counts Open
Weak-lensing peak counts provide a straightforward way to constrain cosmology by linking local maxima of the lensing signal to the mass function. Recent applications to data have already been numerous and fruitful. However, the importance …

On the realistic validation of photometric redshifts Open
Two of the main problems encountered in the development and accurate\nvalidation of photometric redshift (photo-z) techniques are the lack of\nspectroscopic coverage in feature space (e.g. colours and magnitudes) and the\nmismatch between …

Cosmology with weak-lensing peak counts Open
Weak gravitational lensing (WL) causes distortions of galaxy images and probes massive structures on large scales, allowing us to understand the late-time evolution of the Universe. One way to extract the cosmological information from WL i…

Cosmological constraints with weak lensing peak counts and second-order statistics in a large-field survey Open
Peak statistics in weak lensing maps access the non-Gaussian information contained in the large-scale distribution of matter in the Universe. They are therefore a promising complement to two-point and higher-order statistics to constrain o…
