Isomeric Effect of a π Bridge in an IDT-Based Nonfused Electron Photovoltaic Acceptor.

A pair of isomers, IDT-BOF containing S⋅⋅⋅O/F⋅⋅⋅H noncovalently configurational locks and IDT-BFO containing F⋅⋅⋅H/O⋅⋅⋅H noncovalently configurational locks, with an acceptor-π-donor-π-acceptor (A-π-D-π-A) structure have been designed and synthesized by choosing 4,9-dihydro-s-indaceno[1,2-b : 5,6-b']dithiophene (IDT) as the D unit, an F/n-hexyloxy substituted phenyl ring as π bridge, and 3-(dicyanomethylidene)indan-1-one as the A unit. Owing to the S⋅⋅⋅O/F⋅⋅⋅H or F⋅⋅⋅H/O⋅⋅⋅H noncovalently configurational locks, both IDT-BOF and IDT-BFO have a completely planar structure. IDT-BOF exhibits a similar LUMO to IDT-BFO, but higher HOMO energy levels, leading to a smaller optical bandgap and red-shifted absorption.

A Recognition Method of Ewe Estrus Crawling Behavior Based on Multi-Target Detection Layer Neural Network.

There are some problems with estrus detection in ewes in large-scale meat sheep farming: mainly, the manual detection method is labor-intensive and the contact sensor detection method causes stress reactions in ewes. To solve the abovementioned problems, we proposed a multi-objective detection layer neural network-based method for ewe estrus crawling behavior recognition. The approach we proposed has four main parts.

Semiconducting Copolymers with Naphthalene Imide/Amide π-Conjugated Units: Synthesis, Crystallography, and Systematic Structure-Property-Mobility Correlations.

In a series of n-type semiconducting naphthalene tetracarboxydiimide (NDI)-dithiophene (T2) copolymers, structural and electronic properties trends are systematically evaluated as the number of NDI carbonyl groups is reduced from 4 in NDI to 3 in NBL (1-amino-4,5-8-naphthalene-tricarboxylic acid-1,8-lactam-4,5-imide) to 2 in NBA (naphthalene-bis(4,8-diamino-1,5-dicarboxyl)-amide). As the NDI-T2 backbone torsional angle falls the LUMO energy rises. However, the thienyl attachment regiochemistry also plays an important role in less symmetric NBL and NBA.

Evaluation on the application of transcranial Doppler (TCD) and electroencephalography (EEG) in patients with vertebrobasilar insufficiency.

Background: To evaluate the diagnostic value of transcranial Doppler (TCD) and electroencephalography (EEG) in patients with vertebrobasilar insufficiency (VBI) during clinical diagnosis and treatment METHODS: Eighty patients diagnosed with VBI in our hospital from June 2018 to December 2019 were randomly selected as the observation group, and 80 healthy people who received physical examination in the same period were selected as the control group. The abnormal rate, main performance and results, and the peak velocity of blood flow and vertebrobasilar artery blood flow of the two groups were compared.

Results: The abnormal rate of EEG and TCD in VBI patients was 38.

A Cohort Study on Associations between Fundus/intraocular Pressure Abnormality and Medical Check-up Items.

Purpose: To evaluate the associations between medical check-up items (MCI) for fundus and intraocular pressure abnormality (FIPA) diseases in the Department of Health Management Centre, the Fifth Affiliated Hospital of Sun Yat-sen University (DHMC-FHS).

Patients And Methods: Individuals who visited DHMC-FHS and underwent MCI between June 2017 to May 2019 were included, 3237 subjects. A total of 356 participants were diagnosed as FIPA and enrolled.

[Meta-analysis of calcium chemotherapeutic effect of anterior cervical subtotal vertebroplasty and posterior laminoplasty].

Objective: To systematically assess the efficacy of anterior cervical corpectomy and fusion (ACCF) versus posterior laminoplasty (LAMP) for cervical ossification of posterior longitudinal ligament (OPLL).

Methods: PubMed and EMBASE, Cochrane Library, CBM, CNKI, Wanfang and VIP were collected from 7 databases of ACCF, LAMP from 1970 to May 2018. According to the criteria, the articles were included and independently screened by two authors.

[Auxiliary analgesic effect of wrist-ankle acupuncture on patients undergoing transforaminal endoscope surgery].

Objective: To observe the auxiliary analgesic effect of wrist-ankle acupuncture on patients undergoing transforaminal endoscope surgery.

Methods: A total of 64 patients with lumbar disc herniation who underwent percutaneous lateral transforaminal endoscope surgery were randomly divided into an observation group and a control group, 32 cases in each group. The patients in the control group were treated with injection of 1% lidocaine for routine local infiltration anesthesia.

The First Complete Genome Sequence of a Novel RNA Virus-1 (TbRV-1).

The complete sequence of a novel RNA virus isolated from (TbRV-1) was determined to be 12,239 nucleotides in length with five non-overlapping, linearly arranged coding sequences (CDS), potentially encoding nucleoproteins, hypothetical proteins, matrix proteins, glycoproteins, and RNA-dependent RNA polymerases. Sequence analysis indicated that the RNA-dependent RNA polymerase of TbRV-1 shares a 65% nucleotide and 67% amino acid sequence identity with Hubei dimarhabdovirus 2, suggesting that TbRV-1 is a member of the dimarhabdovirus supergroup. This corresponded to the result of the phylogenetic analysis.

Isomers of Dithienocyclopentapyrene-Based Non-Fullerene Electron Acceptors: Configuration Effect on Photoelectronic Properties.

One pair of isomers, centrosymmetric anti-Py-1 and axisymmetric syn-Py-2, was designed and synthesized with an acceptor-donor-acceptor (A-D-A) structure by choosing dithienocyclopentapyrene with four 4-hexylphenyl side chains as the D unit, and 2-(5,6-difluoro-3-oxo-2,3-dihydro-1H-inden-1-ylidene) malononitrile as the A unit. In-depth structure-property relationship studies revealed that the isomers have similar UV/Vis absorption, fluorescence emission, and energy levels but significant differences in molecular shape, polarity, and charge mobility. Solution-processed bulk-heterojunction (BHJ) small-molecule organic solar cells with Py-1 as the electron-acceptor material and PTB7-Th as the electron-donor material exhibit a power conversion efficiency (PCE) of 6.

Metal-Free Decarboxylative Alkoxylation of 2-Picolinic Acid and Its Derivatives with Cyclic Ethers: One Step Construction of C-O and C-Cl Bonds.

A new strategy for the metal-free decarboxylative alkoxylation of 2-picolinic acid and its derivatives is described. The three-component reaction of 2-picolinic acid or its derivatives, cyclic ethers, and BuOCl proceeded smoothly in the presence of a catalytic amount of p-chloranil to produce 2-alkoxylated pyridines with an ω-chlorine atom in satisfactory to excellent yields. New C-O and C-Cl bonds were generated in one step.

Synthesis of 3H-Benzo[e]indoline and Its Application to Small-Molecule Organic Solar Cells.

A squaraine-based small molecule (USQ-BI) bearing 3H-benzo[e]indoline was synthesized as an electron donor, and the corresponding organic solar cells show power conversion efficiency of 5.35 % with an excellent short circuit current of over 15 mA cm . The hole mobility of USQ-BI was about 5 times (9.

Photovoltaic Devices Prepared through a Trihydroxy Substitution Strategy on an Unsymmetrical Squaraine Dye.

A series of unsymmetrical arene-1,3-squaraine (USQ) derivatives with two, three, or four hydroxy (-OH) substituents, namely, USQ-2-OH, USQ-3-OH, or USQ-4-OH, respectively, were designed and synthesized, and the effect of the number of hydroxy groups on the optoelectronic properties of USQs were investigated. Despite the three compounds having similar UV/Vis absorption and HOMO energy levels, solution-processed bulk-heterojunction (BHJ) small-molecule organic solar cells with USQ-3-OH as electron-donor materials exhibit the highest power conversion efficiency of 6.07 %, which could be mainly attributed to the higher hole mobility and smaller phase separation.

An Azulene-Containing Low Bandgap Small Molecule for Organic Photovoltaics with High Open-Circuit Voltage.

A simple azulene-containing squaraine dye (AzUSQ) showing bandgap of 1.38 eV and hole mobility up to 1.25×10(-4)  cm(2)  V(-1)  s(-1) was synthesized.

[Analysis of polymorphic RAPD fragments in P. Taiwanensis Hayata using an integrated microflluidic chip-based system].

Randomly amplified polymorphic DNA (RAPD) markers quickly provide linkage information, especially in conifers where haploid megagametophytes can be used for genotyping. Traditionally use of slab gel electrophresis results in qualitative data that can be manually manipulated to gain semiquantitative information about the polymorphic RAPD fragments. We have proposed the use of an integrated microfluidic chip-based system as a new tool in the analysis of polymorphic RAPD fragments.
