Governance Obstacles to Geothermal Energy Development in Indonesia
Despite having 40 per cent of the world’s potential for geothermal power production, Indonesia exploits less than five per cent of its own geothermal resources.

330 mJ single-frequency Ho:YLF slab amplifier [PDF]
We report on a double-pass Ho:YLF slab amplifier which delivered 350 ns long single-frequency pulses of up to 330 mJ at 2064 nm, with a maximum M-2 of 1.5 at 50 Hz.

Robust Spot Melting by 3D Spot Arrangements in Electron Beam Powder Bed Fusion
This work proposes an approach to replace separately melted contours for spot melting in electron beam powder fusion. Adapting the spot arrangements close to the contour combined with stacking yields a comparable surface quality without the inherent challenges of separate contours, as demonstrated, by electron optical images and roughness measurements.

Resilience of the Communist Party of Vietnam’s Authoritarian Regime since Doi Moi
Unlike communist parties in the former Soviet Union and Eastern and Central Europe, the Communist Party of Vietnam (CPV) has overcome crises to remain in power for the last 30 years and will most likely continue ruling in the coming decades.

This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.

The study presents biodegradable and recyclable mixed‐matrix membranes (MMMs), hydrogels, and cryogels using luminescent nanoscale metal‐organic frameworks (nMOFs) and biopolymers. These bio‐nMOF‐MMMs combine europium‐based nMOFs as probes for the status of the materials with the biopolymers agar and gelatine and present alternatives to conventional ...

ASEAN’s Preferential Trade Agreements (PTA) Strategy
This paper provides a diversification explanation in order understand the development of PTAs in Southeast Asia. I argue that an important reason why ASEAN states participate in PTAs has been to diversify existing trade ties and to reduce overdependence ...

An Inefficient Representation of the Empty Word [PDF]
We show that Post's system of tag with alphabet $\{0,1\}$, deletion number 3, productions $0\rightarrow 00$ and $1\rightarrow 1101$, and initial string $111\cdots 1$ (330 times) converges to the empty word after a very large number of rewriting ...

Laser‐Induced Graphene from Waste Almond Shells
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.
