Synthetic APIs: Enabling Language Models to Act as Interlocutors Between Natural Language and Code

Large language models (LLMs) can synthesize code from natural language descriptions or by completing code in-context. In this paper, we consider the ability of LLMs to synthesize code, at inference time, for a novel API not in its training data, and specifically examine the impact of different API designs on this ability. We find that: 1) code examples in model training data seem to facilitate API use at inference time; 2) hallucination is the most common failure mode; and 3) the designs of both the novel API and the prompt affect performance. In light of these findings, we introduce the concept of a Synthetic API: an API designed to be used by LLMs instead of by humans. Synthetic APIs for LLMs offer the potential to further accelerate development of natural language interfaces to arbitrary tools and services

Deviations from early--time quasilinear behaviour for the quantum kicked rotor near the classical limit

We present experimental measurements of the mean energy for the atom optics kicked rotor after just two kicks. The energy is found to deviate from the quasi--linear value for small kicking periods. The observed deviation is explained by recent theoretical results which include the effect of a non--uniform initial momentum distribution, previously applied only to systems using much colder atoms than ours

Maximizing The Value Of Your Small Business

This paper offers business owners a step-by-step valuation process for establishing the fair market value of their firms and stresses the importance of preparing for the due diligence process

The Role Of Due Diligence In The Business Valuation Process

The due diligence process enables investors to do a better job of determining the appropriate price to pay for a privately held firm.  This article delineates some factors that a prospective buyer should investigate thoroughly to determine the value of a small, privately held business under consideration for purchase

Pedagogical Strategies For Incorporating Behavioral Finance Concepts In Investment Courses

The traditional approach to teaching a course in investments is predicated upon the efficient market hypothesis, modern portfolio theory, and the assumption that decision-makers are rational, wealth optimizing entities.  Recent developments in the arena of behavioral finance (BF) have raised questions about this approach. Although the idea of efficient markets is widely accepted in academic circles, financial markets often fail to behave as predicted by the theory. For the teacher of undergraduate investments, these divergent views create significant pedagogical challenges and opportunities. BF has particular implications for investing in financial markets, where the faith in rational behavior is perhaps the greatest.  This paper identifies alternative strategies for dealing with these issues in the classroom

Strongly aligned and oriented molecular samples at a kHz repetition rate

We demonstrate strong adiabatic laser alignment and mixed-field orientation at kHz repetition rates. We observe degrees of alignment as large as cos\Theta=0.94 at 1 kHz operation for iodobenzene. The experimental setup consist of a kHz laser system simultaneously producing pulses of 30 fs (1.3 mJ) and 450 ps (9 mJ). A cold 1 K state-selected molecular beam is produced at the same rate by appropriate operation of an Even-Lavie valve. Quantum state selection has been obtained using an electrostatic deflector. A camera and data acquisition system records and analyzes the images on a single-shot basis. The system is capable of producing, controlling (translation and rotation) and analyzing cold molecular beams at kHz repetition rates and is, therefore, ideally suited for the recording of ultrafast dynamics in so-called "molecular movies".Comment: 6 pages, 4 figures, in press in Mol.

Two-state wave packet for strong field-free molecular orientation

We demonstrate strong laser-field-free orientation of absolute-ground-state carbonyl sulfide molecules. The molecules are oriented by the combination of a 485-ps-long non-resonant laser pulse and a weak static electric field. The edges of the laser pulse create a coherent superposition of two rotational states resulting in revivals of strong transient molecular orientation after the laser pulse. The experimentally attained degree of orientation of 0.6 corresponds to the theoretical maximum for mixing of the two states. Switching off the dc field would provide the same orientation completely field-free

Knife edge skimming for improved separation of molecular species by the deflector

A knife edge for shaping a molecular beam is described to improve the spatial separation of the species in a molecular beam by the electrostatic deflector. The spatial separation of different molecular species from each other as well as from atomic seed gas is improved. The column density of the selected molecular-beam part in the interaction zone, which corresponds to higher signal rates, was enhanced by a factor of 1.5, limited by the virtual source size of the molecular beam.Comment: 3 pages, 2 figure
