Unleashing the Power of ChatGPT for Translation: An Empirical Study

The recently released ChatGPT has demonstrated surprising abilities in natural language understanding and natural language generation. Machine translation is an important and extensively studied task in the field of natural language processing, which heavily relies on the abilities of language understanding and generation. Thus, in this paper, we explore how to assist machine translation with ChatGPT. We adopt several translation prompts on a wide range of translations. Our experimental results show that ChatGPT with designed translation prompts can achieve comparable or better performance over professional translation systems for high-resource language translations but lags behind significantly on low-resource translations. We further evaluate the translation quality using multiple references, and ChatGPT achieves superior performance compared to the professional systems. We also conduct experiments on domain-specific translations, the final results show that ChatGPT is able to comprehend the provided domain keyword and adjust accordingly to output proper translations. At last, we perform few-shot prompts that show consistent improvement across different base prompts. Our work provides empirical evidence that ChatGPT still has great potential in translations

Organic solar cells based on non-fullerene acceptors.

Organic solar cells (OSCs) have been dominated by donor:acceptor blends based on fullerene acceptors for over two decades. This situation has changed recently, with non-fullerene (NF) OSCs developing very quickly. The power conversion efficiencies of NF OSCs have now reached a value of over 13%, which is higher than the best fullerene-based OSCs. NF acceptors show great tunability in absorption spectra and electron energy levels, providing a wide range of new opportunities. The coexistence of low voltage losses and high current generation indicates that new regimes of device physics and photophysics are reached in these systems. This Review highlights these opportunities made possible by NF acceptors, and also discuss the challenges facing the development of NF OSCs for practical applications

[N,N′-Bis(3-meth­oxy-2-oxidobenzyl­idene)ethyl­enediammonium-κ4 O,O′,O′′,O′′′]tris­(nitrato-κ2 O,O′)dysprosium(III)

In the title mononuclear Schiff base complex, [Dy(NO3)3(C18H20N2O4)], the DyIII ion is ten-coordinated in a distorted hexa­deca­hedral geometry by six O atoms of three nitrate anions and four O atoms of the Schiff base ligand. An intra­molecular N—H⋯O hydrogen bond occurs. The crystal structure is stabilized by inter­molecular C—H⋯O hydrogen bonds

Th17 Cells Paradoxical Roles in Melanoma and Potential Application in Immunotherapy

The progressive infiltration of immune cells is associated with the progression of melanoma. Specifically, Th17 cells in melanoma microenvironment have both antitumor and protumor effects. It is now necessary to understand the contradictory data associated with how Th17 cells play a role in melanoma. This review will summarize the current knowledge regarding the potential mechanisms that may be involved in the effects of Th17 cells in melanoma progression. Currently, since adoptive transferring Th17 cells has been successful in eradicating melanoma in mice, it offers promise for next-generation adoptive cell transfer, as ex vivo expanded stemness-like memory Th17 cells which are induced by distinct cytokines or pharmacologic reagents may be infused into melanoma patients to potentiate treatment outcome

catena-Poly[[bis­(nitrato-κO)cobalt(II)]-bis­[μ-1,4-bis­(pyridin-3-ylmeth­oxy)benzene-κ2 N:N′]]

In the title compound, [Co(NO3)2(C18H16N2O2)2]n, the CoII ion is located on an inversion center and is six-coordinated in an octa­hedral environment defined by four N atoms of the pyridine rings and two O atoms of the nitrate anions. The ligands link the CoII ions into a linear chain running along [201]. One O atom of the nitrate ligand is disordered over two positions with site-occupancy factors of 0.59 (4) and 0.41 (4)

catena-Poly[[bis­(nitrato-κ2 O,O′)cobalt(II)]-μ-4,4′-bis­(pyrazol-1-ylmeth­yl)biphenyl-κ2 N 2:N 2′]

In the title compound, [Co(NO3)2(C20H18N4)]n, the CoII atom lies on a crystallographic twofold axis and the coordination geometry can be considered as a slightly distorted tetra­hedron defined by two O atoms from two nitrate groups and two N atoms from two ligand mol­ecules. A distorted octa­hedron may be assumed when two of the symmetry-related nitrate O atoms with Co—O distances of 2.3449 (19) Å are added to the coordination environment. Another twofold axis, passing through the middle of the biphenyl bonds, is observed in the crystal structure. A chain is built up by the ligands linking the CoII ions along [101]
