How to Achieve High Spatial Resolution in Organic Optobioelectronic Devices?

open access: yesAdvanced Materials Interfaces, EarlyView.
This study explores how the optoelectronic properties of organic semiconductors impact on the resolution of light‐activated bioelectronic interfaces. Using photovoltage and photocurrent microscopy techniques, the authors show that H2PC/PTCDI heterojunctions enable a resolution down to 6.5 µm due to low carrier mobility along the heterojunction.

Nucleosynthesis constraints on the faint vector portal

open access: yesEPJ Web of Conferences, 2015
New Abelian U(1)′ gauge bosons Vμ can couple to the Standard Model through mixing of the associated field strength tensor Vμν with the one from hypercharge, FμνY.

Scientific Visualization in Astronomy: Towards the Petascale Astronomy Era [PDF]

open access: yes, 2011
Astronomy is entering a new era of discovery, coincident with the establishment of new facilities for observation and simulation that will routinely generate petabytes of data. While an increasing reliance on automated data analysis is anticipated, a critical role will remain for visualization-based knowledge discovery.

Organic Ferroelectric Synaptic Transistors for Neural Image Recognition Networks

open access: yesAdvanced Materials Interfaces, EarlyView.
All organic transistors, where both the dielectric and semiconducting layers are polymeric, are developed as electrical synaptic devices. Two copolymers of PVDF as the dielectric layer with large differences in their saturation polarizability and memory window are chosen.

Big Bang in dipole cosmology

open access: yesEuropean Physical Journal C: Particles and Fields
We continue the study of dipole cosmology framework put forward in Krishnan et al. (JCAP 07:020, 2023), a beyond FLRW setting that has a preferred direction in the metric which may be associated with a cosmological tilt, a cosmic dipole.

Fourth Time's a XARM [PDF]

open access: yesarXiv, 2018
Arguably, no mission changed X-ray astronomy in as short a time as did Hitomi. The planned X-ray Astronomy Recovery Mission, XARM, will carry its legacy forward.

High Energy Cosmic Ray and Neutrino Astronomy [PDF]

open access: yes, 2011
Cosmic-rays with energies exceeding 10^{19} eV are referred to as Ultra High Energy Cosmic Rays (UHECRs). The sources of these particles and their acceleration mechanism are unknown, and for many years have been the issue of much debate. The first part of this review describes the main constraints, that are implied by UHECR observations on the ...

All-flavour high-energy neutrino astronomy with KM3NeT/ARCA

open access: yes, 2016
The recent discovery by the IceCube collaboration of a high-energy neutrino flux of extraterrestrial origin has opened a new observational window on the Universe.

Contactless Tracking of Decomposition in Self‐Reporting Ceramic Cr‐Al‐B Coatings

open access: yesAdvanced Materials Interfaces, EarlyView.
Proof of concept for contactless tracking of decomposition in self‐reporting ceramic Cr‐Al‐B coatings in extreme environments by contactless resistivity measurements is demonstrated. To verify the results, high resolution in situ and ex situ methods are employed.

Yield estimation of summer maize based on multi‐source remote‐sensing data

open access: yesAgronomy Journal, Volume 114, Issue 6, Page 3389-3406, November/December 2022., 2022
Abstract Accurately estimating regional‐scale crop yields is substantial in determining current agricultural production performance and effective agricultural land management. The Yuncheng Basin is an important grain‐producing area in the Shanxi Province. This paper used Sentinel 2A with a spatial resolution of 10 m and MODIS with a temporal resolution
