To do so, a possibility is to evaluate the considered LLM on a set of task instances and train an assessor to predict its performance based on features of the instances. However, this ap... | https://arxiv.org/abs/2409.03563v1 |
Pre-training is notoriously compute-intensive and academic researchers are notoriously under-resourced. It is, therefore, commonly assumed that academics can't pre-train models. In this paper, we seek to clarify this assumption. We first survey academic researchers to learn about their available compute and then empiri... | https://arxiv.org/abs/2410.23261v1 |
A target using a paisley pattern generates 100-kT-level magnetic fields. Laser irradiation induces local charge separation on the target, which creates surface currents along the concave surface, generating a magnetic field. For a laser intensity of $10^{21}$ W/cm$^2$, the target generates a 150-kT magnetic field. We d... | https://arxiv.org/abs/2202.00193v1 |
Long-context capability is considered one of the most important abilities of LLMs, as a truly long context-capable LLM enables users to effortlessly process many originally exhausting tasks -- e.g., digesting a long-form document to find answers vs. directly asking an LLM about it. However, existing real-task-based lon... | https://arxiv.org/abs/2505.19293v1 |
An efficient error reconciliation scheme is important for post-processing of
quantum key distribution (QKD). Recently, a multi-matrix low-density
parity-check codes based reconciliation algorithm which can provide remarkable
perspectives for high efficiency information reconciliation was proposed. This
paper concerns t... | http://arxiv.org/abs/2001.07979v1 |
Metrics can be used by businesses to make more objective decisions based on data. Software startups in particular are characterized by the uncertain or even chaotic nature of the contexts in which they operate. Using data in the form of metrics can help software startups to make the right decisions amidst uncertainty a... | https://arxiv.org/abs/1901.04819v1 |
Based on the dual-chirped optical parametric amplification and type-I BiB$_3$O$_6$(BiBO) crystals, the generation of $>$100 mJ, 10.4 fs, 10 Hz, carrier-to-envelope phase (CEP)-stable laser pulses, which are centered at 1.7 $\mu$m, is demonstrated; it produces a peak power of 10 TW. CEP-dependent high harmonic generatio... | https://arxiv.org/abs/2202.03658v2 |
A scintillating bolometer technology based on $^{100}$Mo-enriched lithium
molybdate (Li$_2$$^{100}$MoO$_4$) crystals has been developed by LUMINEU to
search for neutrinoless double-beta ($0\nu 2\beta$) decay of $^{100}$Mo. The
results of several low temperature tests at underground environments have
proved the reproduc... | http://arxiv.org/abs/1709.07846v1 |
As a consequence of their work on average Selmer ranks of elliptic curves with marked points, Bhargava and Ho proved that $100\%$ of elliptic curves over $\mathbb{Q}$ with an additional marked point have positive rank. In this note we provide an alternate proof which extends the result to global fields of characteristi... | https://arxiv.org/abs/2504.01965v1 |
We study the universal family of odd hyperelliptic curves of genus $g \geq 1$ over $\mathbb{Q}$. We relate the heights of $\mathbb{Q}$-points of Jacobians of curves in this family to the reduction theory of the representation of $\mathrm{SO}_{2g+1}$ on self-adjoint $(2g + 1) \times(2g + 1)$-matrices. Using this theory,... | https://arxiv.org/abs/2405.10224v1 |
We consider a specific family of analytic functions $g_{\alpha,T}(s)$, satisfying certain functional equations and approximating to linear combinations of the Riemann zeta-function and its derivatives of the form $c_0\zeta(s)+c_1\frac{\zeta'(s)}{\log T}+c_2\frac{\zeta''(s)}{(\log T)^2}+\dots+c_{K}\frac{\zeta^{(K)}(s)}{... | https://arxiv.org/abs/1805.07741v6 |
Throughout this manuscript the zeros are counted with multiplicity. We denote by $N(T)$ the number of zeros $\rho$ of $\zeta(s)$ in the critical strip upto height $T$ where $T>3$ is not an ordinate of zero of $\zeta(s)$. Denote by $N_0(T)$ the number of zeros $\rho$ of $\zeta(s)$ on the critical line upto height $T$. W... | https://arxiv.org/abs/2205.00811v10 |
Quantum many-body systems present substantial technical challenges from both analytical and numerical perspectives. Despite these difficulties, some progress has been made, including studies of interacting atomic gases and interacting quantum spins. Furthermore, the potential for criticality to enhance engine performan... | https://arxiv.org/abs/2502.01469v1 |
100 prisoners and a light bulb is a long standing mathematical puzzle. The problem was studied mostly in 2002 [5], 2003 [1], and 2004 [3]. Solutions in published articles had average number of visits above 3850, but best solutions on forums had (declared) average number of visits around 3500. I spent some time in 2007-... | https://arxiv.org/abs/2208.00771v1 |
We describe the results of observations with the 100m Robert C. Byrd Green Bank Telescope (GBT) in the HI line of 105 nearby dwarf galaxies, 60 of which were discovered recently in the DESI Legacy Imaging Surveys. Of 105 objects observed, we detected 77 galaxies with the following median parameters: an HI-flux of 0.69 ... | https://arxiv.org/abs/2505.19248v1 |
