Triarylboranes have attracted significantly increasing research interest as a remarkable class of photoelectronic π-electron materials. Because the presence vacant p orbital on B center, boryl group is very unique electron acceptor that exhibits not only electron-accepting ability through p-π* conjugation but also high Lewis acidity to coordinate with bases and steric bulk arising from aryl substituent center get enough kinetic stability. Thus, incorporation trivalent element into...
The bis(silylene)-based SiC(sp3)Si pincer ligand N,N′-bis(LSi:)dipyrromethane [SiCH2Si] (L1; L = PhC(NtBu)2) with a C(sp3) atom anchor was synthesized, and its coordination chemistry to iron studied. Two novel hydride complexes, [SiCHSi]Fe(H)(N2)(PMe3) (1) [SiCHSi]Fe(H)(PMe3)2 (2), were synthesized in the reaction of L1 Fe(PMe3)4 via C(sp3)–H bond activation under different inert atmospheres (N2 argon). To best our knowledge, 1 2 are first examples hydrido complex produced through bond. At...
In this study, three tetracoordinated bis(silylene) iron(II) chlorides, namely, [SiCHRSi]FeCl2 (1) (R = H), (2) CH3), and (3) Ph), were synthesized through the reactions of different ligands [LSiCHRSiL] (L PhC(NtBu)2, L1 L2 L3 Ph)) with FeCl2·(THF)1.5 in THF. The Fe complexes 1–3 could be used as effective catalysts for dinitrogen silylation, complex 3 demonstrating highest turnover number (TON) 746 equiv among complexes. catalytic mechanism was explored, revealing involvement...
A white LED with a bi-component light emitting layer is reported providing emission CIE of (0.38, 0.40), CRI 71, and maximum EQE 12.5%. These are among the best for based devices.
In this paper, we have disclosed efficient room-temperature phosphorescence (RTP) in the amorphous state from a triarylborane-based biphenyl derivative, 4,4′-dibromo-2-dimesitylboryl-2′-(N,N-dimethylamino)biphenyl (Br2-BN-BPh). The quantum yields of vigorously ground powder and drop-cast film are 0.36 0.22, respectively. Owing to presence two bulky substituents at lateral positions, existence intramolecular π–π interaction B···N electronic interaction, compound is intramolecularly rigid,...
Background Early and accurate identification of lymphatic node metastasis (LNM) vascular space invasion (LVSI) for endometrial cancer (EC) patients is important treatment design, but difficult on multi‐parametric MRI (mpMRI) images. Purpose To develop a deep learning (DL) model to simultaneously identify LNM LVSI EC from mpMRI Study Type Retrospective. Population Six hundred twenty‐one with histologically proven two institutions, including 111 LNM‐positive 168 LVSI‐positive, divided into...
Endometrial Cancer (EC) is a highly heterogeneous cancer comprising both histological and molecular subtypes. Using non-invasive modality method to trigger these subtypes as early possible can aid clinicians in establishing individualized treatment.
The triarylborane<bold>o,o′-NPh2</bold>exhibits high triplet energy and can be used as an efficient host for blue green phosphorescent OLEDs.
A triarylborane exhibits significant fluorescence enhancement abruptly at a specific high temperature and can remain intensely emissive even after cooling to room temperature.
Radar specific emitter identification (SEI) involves extracting distinct fingerprints from radar signals to precisely attribute them corresponding transmitters. In view of the limited characterization fingerprint information by single-domain features, this paper proposes utilization multi-domain mixed kernel canonical correlation analysis for SEI. Initially, leveraging complementarity across diverse feature domains, features are extracted four domains including: envelope feature, spectrum...
Interrupted sampling repeater jamming (ISRJ) is an effective method in modern electronic countermeasures, but its duty ratio (SDR) should be no more than 50%. This paper proposes a distributed interrupted solution to settle this problem based on the basic principle of ISRJ. The simulation results show that can break limit SDR, and overcome inherent defects single ISRJ jammer.
In the circuit quantum electrodynamics architectures, to realize a long-range network mediated by flying photon, it is necessary shape temporal profile of emitted photons achieve high transfer efficiency between two nodes. this work, we demonstrate new single-rail and dual-rail time-bin shaped photon generator without additional flux-tunable elements, which can act as interface point-to-point network. our approach, adopt qubit-resonator-transmission line configuration, effective coupling...
Distributed interrupted sampling repeater jamming (D-ISRJ) is the application of technology within framework distributed systems. It can generate coherent false targets after passing through target radar’s matched filter, but these exhibit strong regularity in range and amplitude. Addressing this issue, a frequency-shifted method based on group teaching optimization algorithm (GTOA) proposed paper. By introducing modulation during retransmission signal, frequency shift amount unit each round...
To investigate the added value of T1-mapping to arterial spin labeling (ASL) for computer-aided early diagnosis Alzheimer’s disease (AD). A total 97 (45 AD/24 mild cognitive impairment (MCI)/38 normal control (NC)) people were enrolled retrospectively. We extracted features from 24 automatically segmented brain regions based on and ASL MR images constructed three radiomics models differentiate AD-NC/MIC-NC/AD-MCI, which achieved a favorable prediction performance with AUCs 0.921/0.764/0.727,...
We assessed the performance of diffusion models for assessing response to neoadjuvant chemotherapy (NACT) using machine learning. Firstly, features were extracted from region interest on different parametric maps esophageal squamous cell carcinoma (ESCC) patients and changes parameters (Δ parameter) before after NACT (pre-NACT post-NACT) calculated. Then Δ-NACT pre-NACT built models. The results demonstrated that may be used predict efficacy in ESCC patients.
Sinonasal mucosal melanomas (SNMM) are clinically more aggressive than its cutaneous counterpart and presented markedly poor prognosis. To differentiate sinonasal from lymphomas, a radiomics model was built using features multi-parametric MRI, including T1-weighted imaging (T1WI), T2 weighted (T2WI), DWI C-T1WI. In this multicenter retrospective study, 189 patients diagnosed with SNMMs or lymphoma were enrolled three institutions. The proposed achieved AUCs of 0.884 0.870 in the internal...
Two new triarylborane-based o,o'-substituted 2,2'-bithienyls, BT-BNMe2 and BT-BNBn2 , which contain BMes2 NMe2/NBn2 groups at the 3,3'-positions, have been synthesized. Similar to biphenyl analogues, BP-BNMe2 BP-BNBn2 2,2'-positions, steric effect of amino group has significant influence on conformation 2,2'-bithienyl skeleton. The boryl are located same side 2,2'-bithienyls axis with a short B···N distance (3.63 Å) for NMe2-substituted . On contrary, two substituents arranged different...
