CoCoFormer: A controllable feature-rich polyphonic music generation method
This paper explores the modeling method of polyphonic music sequence. Due to
the great potential of Transformer models in music generation, controllable
music generation is receiving more attention. In the task of polyphonic music,
current controllable generation research focuses on controlling the generation
of chords, but lacks precise adjustment for the controllable generation of
choral music textures. This paper proposed Condition Choir Transformer
(CoCoFormer) which controls the output of the model by controlling the chord
and rhythm inputs at a fine-grained level. In this paper, the self-supervised
method improves the loss function and performs joint training through
conditional control input and unconditional input training. In order to
alleviate the lack of diversity on generated samples caused by the teacher
forcing training, this paper added an adversarial training method. CoCoFormer
enhances model performance with explicit and implicit inputs to chords and
rhythms. In this paper, the experiments proves that CoCoFormer has reached the
current better level than current models. On the premise of specifying the
polyphonic music texture, the same melody can also be generated in a variety of
ways
3,5-Di-O-benzoyl-1,2-O-isopropylidene-α-d-ribo-hexos-3-ulo-1,4:3,6-difuranose
The title compound, C23H22O8, is a binary benzoyl ester whose nucleus consists of a fused system made up of a methylenedioxy ring and two tetrahydrofuran rings. One of the benzoyl ester groups is attached at the junction of the two tetrahydrofuran rings. The other is attached to the outer tetrafuran ring. Both the benzoyl ester groups are in an axial conformation with respect to the outer tetrhydrofuran ring. In the crystal, molecules are linked by two weak C—H⋯O hydrogen bonds, forming a chain running parallel to the a axis

The correlation between the expression of differentiated embryo-chondrocyte expressed gene l and oral squamous cell carcinoma
BACKGROUND: This study aims to explore the correlation between expression of differentiated embryo-chondrocyte expressed gene l (DEC1) and oral squamous cell carcinoma (OSCC), which could provide the reference for treatment and prognosis assessment of OSCC. METHODS: The expression of DEC1 in tissues from 56 primary OSCC patients and 20 normal oral mucosa samples were detected using real-time polymerase chain reaction and immunohistochemical methods, respectively. RESULTS: The results showed that the positive expression rate of DEC1 in the OSCC group was significantly higher than that in the normal group (P <0.05); further, the expression of DEC1 in different OSCC groups was statistically significant (P <0.05). The expression of DEC1 in the 1-year recurrence OSCC group was significantly higher than other groups. The expression of DEC1 in the 3-years no recurrence OSCC group was the lowest. CONCLUSIONS: The expression of DEC1 was associated with the incidence of OSCC and there was a negative correlation between the expression of DEC1 and the prognosis of OSCC
Developmental potential of non- and mono-pronuclear zygotes and associated clinical outcomes in IVF cycles
PurposeThis study aims to evaluate the developmental potential of 0PN, 1PN, and 2PN zygotes in IVF cycles and compare their clinical outcomes.MethodsWe conducted a retrospective cohort study involving IVF patients. Blastocyst formation rates were assessed with 0PN, 1PN, and 2PN zygotes. Subsequently, we collected clinical outcome data following the transfer of these zygotes.ResultsThe overall blastulation rate was similar between 0PN (29.6%) and 2PN (32.1%) zygotes, but 1PN zygotes exhibited a significantly lower blastulation rate (17.0%) compared to both 0PN and 2PN zygotes. Similarly, the overall rate of good-quality blastulation was comparable between 0PN (15.3%) and 2PN (17.5%) zygotes, while 1PN zygotes showed a significantly lower rate (7.0%) compared to both 0PN and 2PN. Clinical pregnancy, ectopic pregnancy, implantation, and live birth rates were similar among single blastocyst frozen embryo transfers (FET) of 0PN, 1PN, and 2PN. Additionally, no significant differences were observed between single- and double-blastocyst FET of 0PN and 2PN.ConclusionsOur findings suggest that 0PN and 2PN zygotes have comparable developmental potential, while 1PN embryos exhibit lower developmental potential. Blastocyst FET outcomes appear similar among 0PN, 1PN, and 2PN zygotes
