Orbit and clock products for quad-system satellites with undifferenced ambiguity fixing approach
Satellite NavigationInteger Ambiguity Resolution (IAR) can significantly improve the accuracy of GNSS Precise Orbit Determination (POD). Traditionally, the IAR in POD is achieved at the Double Differenced (DD) level.

Reference dependence and lottery participation
Economic Inquiry, EarlyView.Abstract We assume that lottery participants are poor relative to their target income. Reference dependence with loss aversion can render the marginal utility of income non‐monotonic in line with the Friedman–Savage hypothesis. As a result, lottery participation can be rationalized without invoking probability weighting.

Do Banks Learn From Natural Disasters? Evidence From the U.S. Financial Sector
European Financial Management, EarlyView.ABSTRACT This paper examines whether U.S. banks learn from natural disasters. We explore several potential channels of adjustment and find that exposed banks primarily respond by adopting precautionary capital measures. This behaviour is evident both in the long run, when assessing divergent trends in the evolution of equity over time, and in the short

From Regression to Reasoning: Predicting M&A Announcement Returns With Large Language Models
European Financial Management, EarlyView.ABSTRACT This study investigates whether large language models (LLMs) can predict short‐term market reactions to M&A announcements. We prompt OpenAI's latest reasoning models (o3, GPT‐5, and GPT‐5.1) to forecast whether the combined market value of acquirer and target will increase or decrease, drawing on deal‐, firm‐, and macroeconomic data for large ...

A baseline constrained LAMBDA method for integer ambiguity resolution of GNSS attitude systems.
, 2008 In this paper, an efficient integer ambiguity resolution method for GNSS attitude determination system is described. The proposed method solves the integer least-squares with quadratic equality constraints(ILSQE) problem and shows an expansion of the ...

Rational Expectations Fools' Bubbles
International Economic Review, EarlyView.ABSTRACT We develop a rational, Walrasian model of speculative bubbles inspired by the Kindleberger–Minsky view, which describes bubbles as wave‐like market processes. Touched off by an initial shock, price booms are initially self‐reinforcing but become self‐destructive later when prices surpass fundamental value.

International Transactions in Operational Research, EarlyView.Abstract Despite increasing demands for resilient and sustainable supply chains, inventory management often relies on outdated single‐criterion analyses. While multi‐criteria ABC (MCABC) analyses provide a theoretically mature assessment of resilience‐sustainability‐benefit trade‐offs in inventory, their adoption remains limited due to fragmented ...

International Transactions in Operational Research, EarlyView.Abstract We address the scheduling conflicting jobs on parallel identical machines problem with makespan minimization, a classical and computationally challenging variant of parallel machine scheduling. We develop and evaluate three distinct solution methodologies: a novel constraint programming (CP) formulation, and two metaheuristics: a multi ...

The Volume of the GPS Ambiguity Search Space and its Relevance for Integer Ambiguity Resolution
, 1996 In the theory of integer least-squares ambiguity estimation and validation, a central role is played by the ambiguity search space. In this contribution, the significance of the volume of the ambiguity search space is discussed and analyzed.
