Efficiency of three-terminal thermoelectric transport under broken-time reversal symmetry

open access: yes, 2013
We investigate thermoelectric efficiency of systems with broken time reversal symmetry under a three-terminal transport. Using a model of Aharonov-Bohm interferometer formed with three noninteracting quantum dots, we show that Carnot efficiency can be ...

The Effects of Gas Angular Momentum on the Formation of Magnetically Arrested Disks and the Launching of Powerful Jets

open access: yesThe Astrophysical Journal Letters, 2023
In this letter, we investigate Bondi-like accretion flows with zero or low specific angular momentum by performing 3D general relativistic magnetohydrodynamic simulations.

The fate of (phantom) dark energy universe with string curvature corrections

open access: yes, 2005
We study the evolution of (phantom) dark energy universe by taking into account the higher-order string corrections to Einstein-Hilbert action with a fixed dilaton.

A Paraffin‐Based Photoresin: 3D Printing of Paraffin for Encapsulation‐Free Shape‐Stabilized Paraffin‐Based Phase Change Materials

open access: yesAdvanced Materials Technologies, Volume 10, Issue 13, July 8, 2025.
A novel approach for fabricating shape‐stabilized paraffin‐based phase change materials via digital light processing 3D printing is demonstrated. The printed components contain up to 60 wt.% paraffin within elastomeric polymer networks, exhibiting excellent shape stability and stretchability.

Wireless Network-Coded Four-Way Relaying Using Latin Hyper-Cubes

open access: yes, 2012
This paper deals with physical layer network-coding for the four-way wireless relaying scenario where four nodes A, B, C and D wish to communicate their messages to all the other nodes with the help of the relay node R.

Radio and X-Ray Emission as Probes of Type IIP Supernovae and Red Supergiant Mass Loss [PDF]

open access: yes, 2005
Type IIP (plateau) supernovae are thought to come from stars with initial mass about 8-25 solar masses that end their lives as red supergiants. The expected stellar end points can be found from evolutionary calculations and the corresponding mass loss ...

Al‐Doped LaTiO2N Prepared via Flame Spray Pyrolysis for Photocatalytic Hydrogen Evolution

open access: yesAdvanced Energy and Sustainability Research, Volume 6, Issue 7, July 2025.
Flame spray pyrolysis enables the synthesis of La–Ti oxides with a simple perovskite‐type structure, and Al doping promotes the formation of the simple perovskite‐type La–Ti oxides. The Al‐doped LaTiO2N obtained by nitridation has a reduced defect concentration due to suppressed structural change, which contributes to the improvement of hydrogen ...

A novel iheyamine A derivative L42 suppresses acute myeloid leukemia via dual regulation of the PI3K/AKT/FOXO3a axis and TNF signaling pathway

open access: yesBiomedicine & Pharmacotherapy
Acute myeloid leukemia (AML) is one of the most common hematopoietic malignancies and the development of new drugs is crucial for the treatment of this lethal disease. Iheyamine A is a nonmonoterpenoid azepinoindole alkaloid from the ascidian Polycitorella sp., and its anticancer mechanism has not been investigated in leukemias.

Development of Z‐Scheme Photocatalyst Systems Combining Nonmetal Oxide Materials for Water Splitting under Visible Light Irradiation: (CuGa)0.5ZnS2 as a H2‐Evolving Photocatalyst and TaON as an O2‐Evolving Photocatalyst

open access: yesAdvanced Energy and Sustainability Research, Volume 6, Issue 7, July 2025.
Z‐schematic water splitting under visible light irradiation using TaON as an O2‐evolving photocatalyst, (CuGa)0.5ZnS2 as a H2‐evolving photocatalyst, and reduced graphene oxide as an electron mediator is achieved. This combination of a metal oxynitride and a metal sulfide photocatalysts is new for a Z‐scheme system for water splitting under visible ...

Multipoint Observations of Magnetic Reconnection in the Martian Magnetotail Triggered by an Interplanetary Magnetic Field Rotation

open access: yesThe Astrophysical Journal Letters
The induced magnetosphere of Mars is highly dynamic, driven by both the upstream solar wind and the planet’s crustal magnetic fields. This variability can occur on timescales much shorter than a single spacecraft orbit, making it difficult to distinguish
