Miners' Reward Elasticity and Stability of Competing Proof‐of‐Work Cryptocurrencies

International Economic Review, EarlyView.
ABSTRACT Proof‐of‐Work cryptocurrencies employ miners to sustain the system through algorithmic reward adjustments. We develop a stochastic model of the multicurrency mining and identify conditions for stable transaction speeds. Bitcoin's algorithm requires hash supply elasticity <$<$1 for stability, while ASERT remains stable for any elasticity and ...

In Situ Analysis of Oxygen Vacancies and Band Alignment in HfO2/TiN Structure for CMOS Applications

Nanoscale Research Letters, 2017
The density of oxygen vacancies characterization in high-k/metal gate is significant for semiconductor device fabrication. In this work, a new approach was demonstrated to detect the density of oxygen vacancies by in situ x-ray photoelectron spectroscopy

Daily entry and exit triggers for open market repurchases

Journal of Financial Research, EarlyView.
Abstract Using publicly available daily data, we analyse the daily decision repurchasing firms make to enter or exit the market during open market repurchase programs. Firms enter the market to repurchase after a stock price downturn and maintain their presence in the market while stock returns remain negative. The lower the preceding overnight return,

Historic disturbance events overruled climatic factors as drivers of ruderal species distributions in the Scandinavian mountains

Nordic Journal of Botany, EarlyView.
The contemporary interaction of climate and disturbance drives vegetation composition and species distribution shifts, making their respective roles difficult to disentangle. This study describes the long‐term ruderal plant species distributions along the ‘Rallarvägen' in Abisko, subarctic Sweden.

A prototype ASIC for APD array readout of scintillating plastic fibers [PDF]

, 2002
We report on the development of custom front-end electronics for use with avalanche photodiode (APD) arrays as part of a NASA technology study for the readout of scintillating plastic fibers. APD arrays featuring 64 1 mm square pixels are used.

Beyond Compliance: The Role of Corporate Governance in Shaping Whistleblower Protection Policies

Regulation &Governance, EarlyView.
ABSTRACT This study investigates the impact of selective good corporate governance practices on the development of mandatory whistleblower protection policies in corporations. Using a coding instrument aligned with legislative requirements, we analyzed 66 whistleblower policies to assess their comprehensiveness and alignment with best practices.

Symbol‐Level GRAND‐Assisted Detection for Polar‐Coded Spatial Modulation in MIMO Systems

International Journal of Communication Systems, Volume 39, Issue 7, 10 May 2026.
This research presents an integrated polar‐coded spatial modulation (PCSM) transceiver scheme for MIMO transmission over Rayleigh fading channels. The proposed architecture employs linear spatial signal processing for antenna and symbol estimation, followed by symbol‐level guessing random additive noise decoding (symbol‐level GRAND)–assisted detection ...

pH‐Dependent Microenvironmental Ionic Signaling in Pancreatic Ductal Adenocarcinoma

Acta Physiologica, Volume 242, Issue 4, April 2026.
ABSTRACT Aim Pancreatic ductal adenocarcinoma (PDAC) develops within a uniquely dynamic pH landscape shaped by substantial acid–base fluxes produced by the exocrine pancreas. Secretion of alkaline pancreatic juice, normally linked to digestion, produces intermittent acidifications of the pancreatic interstitium, which challenges epithelial and stromal ...
