Neural Shading Fields for Efficient Facial Inverse Rendering

open access: yesComputer Graphics Forum, Volume 42, Issue 7, October 2023., 2023
Abstract Given a set of unstructured photographs of a subject under unknown lighting, 3D geometry reconstruction is relatively easy, but reflectance estimation remains a challenge. This is because it requires disentangling lighting from reflectance in the ambiguous observations.

Dust Deposition at Zhurong Landing Site From Multispectral Camera Observations

open access: yesGeophysical Research Letters, Volume 50, Issue 13, 16 July 2023., 2023
Abstract Dust deposition is one of the most predominant processes occurring on Mars. Until now, just a few in situ observations have been conducted to investigate the Martian dust. The Multispectral Camera (MSCam) onboard the Zhurong rover with its calibration target can be used to monitor dust deposition, providing a new ground observation.

Pitfalls of using sequence databases for heterologous expression studies – a technical review

open access: yesThe Journal of Physiology, Volume 601, Issue 9, Page 1611-1623, 1 May 2023., 2023
Abstract figure legend Projects involving heterologous gene expression are often characterised by similar steps. Initially, database research (A) is necessary to retrieve information of full or partial sequences of a gene of interest. A multitude of genome assemblies are annotated and deposited in public databases or are available for refined search ...

Finding SEIS North on Mars: Comparisons Between SEIS Sundial, Inertial and Imaging Measurements and Consequences for Seismic Analysis

open access: yesEarth and Space Science, 2021
In this paper, we present the results obtained in the determination of the true north direction on Mars by using a gnomon on the InSight mission and compare the measurements with either the North determination from the Inertial Measurement Unit and ...

The Mastcam‐Z Radiometric Calibration Targets on NASA's Perseverance Rover: Derived Irradiance Time‐Series, Dust Deposition, and Performance Over the First 350 Sols on Mars

open access: yesEarth and Space Science, Volume 9, Issue 12, December 2022., 2022
Abstract The Mastcam‐Z radiometric calibration targets mounted on the NASA's Perseverance rover proved to be effective in the calibration of Mastcam‐Z images to reflectance (I/F) over the first 350 sols on Mars. Mastcam‐Z imaged the calibration targets regularly to perform reflectance calibration on multispectral image sets of targets on the Martian ...

A Study on the Sundials of the Kang Family of Jinju [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2010
In this paper, we investigate the sundials made by the Kang Family of Jinju in the later period of the Joseon dynasty in terms of their characteristics, functions and the manufacturing technique. One of the characteristics of these sundials is that the

The bronze-age astronomical finds in the territory of Serbia [PDF]

open access: yesSerbian Astronomical Journal, 2001
In the present paper it is shown that among the archeological finds at Vatin some 50 km north-east of Belgrade, there are primeval astronomical instruments: gnomon, metron along with the calendar records, belonging to the proto-astronomic age, which by ...

Fixing the shadows while moving the gnomon [PDF]

open access: yes, 2015
It is a common practice to fix a vertical gnomon and study the moving shadow cast by it. This shows our local solar time and gives us a hint regarding the season in which we perform the observation.

Complex evolutionary dynamics of massively expanded chemosensory receptor families in an extreme generalist chelicerate herbivore [PDF]

open access: yes, 2016
While mechanisms to detoxify plant produced, anti-herbivore compounds have been associated with plant host use by herbivores, less is known about the role of chemosensory perception in their life histories.
