Significant advances have been made in the research of all-fiber speckle spectrometers, and various planar scattering media have also garnered the attention of many researchers. In this study, we designed a compact speckle spectrometer employing a femtosecond laser to induce double-sided nanostructures on a quartz glass as a scattering medium.

Enhancing the magnetic properties of Dy(III) single-molecule magnets in octahedral coordination symmetry by tuning the equatorial ligands.

Conventionally, octahedral () coordination symmetry of lanthanide centers is not ideal for constructing high-performance single-molecule magnets (SMMs). However, introducing a strong ligand field in the axial direction to increase crystal field splitting can potentially overcome this limitation. Herein, we successfully obtained two dysprosium(III) single-molecule magnets, [Dy(OCBu)X(py)] (X = Cl (1), I (2), py = pyridine), in coordination symmetry.

A Novel Low-Density-Biomass-Carbon Composite Coated with Carpet-like and Dandelion-Shaped Rare-Earth-Doped Cobalt Ferrite for Enhanced Microwave Absorption.

A novel low-density composite for the absorption of microwaves was prepared by loading La-doped spinel cobalt ferrite (La-CFO) onto biomass carbon (BC) derived from corn stalks using a hydrothermal method. This composite (La-CFO@BC) not only maintained the advantageous properties of low density and abundant porosity, but also exhibited a unique morphology, with La-CFO displaying a carpet-like structure interspersed with dandelion-shaped particles. The incorporation of La-CFO effectively tuned the electromagnetic parameters of the composite, thereby improving its impedance-matching attributes and its ability to absorb microwave radiation.

In this paper, we investigate the energy efficiency optimization for a parallel relay-assisted underwater wireless optical communication (UWOC) system with simultaneous lightwave information and power transfer (SLIPT) over an aggregate channel. In this system, relay nodes are equipped with energy harvesting devices, getting energy from the direct current component of the received signal transmitted by the source node. These nodes utilize the harvested energy to transmit the signal to the destination node with the decoding and forwarding strategy.

Thoracic endovascular aortic repair of an anastomosis pseudoaneurysm after the Bentall procedure assisted by rapid ventricular pacing: A case report.

Background: Although commonly used for the treatment of descending aortic dissection, endovascular repair is challenging for ascending aortic pseudoaneurysms. Rapid ventricular pacing (RVP), a method that temporarily impedes cardiac output by stopping ventricular activity, heralds potential benefits for thoracic endovascular aortic repair (TEVAR) during precision landing. Recently, we successfully treated an anastomosis pseudoaneurysm after the Bentall procedure using TEVAR assisted by RVP.

Quantum hash function based on controlled alternate lively quantum walks.

Quantum hash function is an important area of interest in the field of quantum cryptography. Quantum hash function based on controlled alternate quantum walk is a mainstream branch of quantum hash functions by virtue of high efficiency and flexibility. In recent development of this kind of schemes, evolution operators determined by an input message depend on not only coin operators, but also direction-determine transforms, which usually are hard to extend.

Understanding the Magnetic Relaxation Mechanism in Mixed-Valence Dilanthanide Complexes with Metal-Metal Bonding: A Theoretical Investigation.

Theoretical investigations on mixed-valence dilanthanide complexes (Cp)LnI (Ln = Tb, Dy, and Ho) indicate that the total spin of the 4f shell couples preferentially to the σ electron spin and then to the orbital angular momentum, improving the strength of spin-orbit coupling (SOC) for each magnetic center. On the other hand, the concentration of negative charges containing the delocalized σ electron in the axial direction leads to a large crystal-field (CF) splitting. Both strong SOC and large CF splitting lead to the largest energy barrier of such complexes up to now.

To tackle this problem, the optimal transmission scheme is decomposed into subchannel assignment and power allocation.

Microwave photonics broadband unambiguous frequency measurement based on a Sagnac loop and a linear optical filter.

We propose an instantaneous frequency measurement (IFM) scheme featured with unambiguous measurement utilizing a Sagnac loop with an embedded bi-directional phase modulator and an optical filter with a linear frequency response. The frequency of the microwave signal to be measured is instantaneously estimated by calculating an amplitude comparison function (ACF) of photocurrents from the upper and lower branches of the proposed structure. Compared to previous IFM schemes, the ACF in the proposed scheme is monotonic, by which the frequency of the unknown microwave signal can be uniquely confirmed without ambiguity.

Endovascular therapy versus medical treatment for spontaneous isolated dissection of the superior mesenteric artery.

Background: Spontaneous isolated dissection of the superior mesenteric artery (SIDSMA) occurs when a tear in the inner layer of the superior mesenteric artery (SMA) allows blood to flow between the layers of the SMA, forcing the layers apart, and creating two lumens. Abdominal pain is the most prevalent clinical manifestation. Other people may have no symptoms or experience nausea, vomiting, diarrhea, or blood in their stools.

Photocontrollable Magnetism and Photoluminescence in a Binuclear Dysprosium Anthracene Complex.

By incorporating photoreactive anthracene moieties into binuclear DyO motifs, we obtain two new compounds with the formulas [Dy(SCN)(L)(dmpma)] () and [Dy(SCN)(L)(dmpma)(CHCN)] (), where HL is 4-methyl-2,6-dimethoxyphenol and dmpma is dimethylphosphonomethylanthracene. Compound contains face-to-face π-π interacted anthracene groups that meet the Schmidt rule for a [4 + 4] photocycloaddition reaction, while stacking of the anthracene groups in compound does not meet the Schmidt rule. Compound undergoes a reversible single-crystal-to-single-crystal structural transformation upon UV-light irradiation and thermal annealing, forming a one-dimensional coordination polymer of [Dy(SCN)(L)(dmpma)(dmpma)] ().

Slow magnetic relaxation in a Dy triangle and a bistriangular Dy cluster.

Two lanthanide single-molecule magnets (SMMs) [Dy(μ-OH)(HL-1)(HO)](NO)·3HO (1, HL-1 = ()-3-(((8-hydroxyquinolin-2-yl)methylene)amino)propane-1,2-diol) and [Dy(μ-OH)(HL-2)(HL-2)(L-2)] (2, HL-2 = ()-2-hydroxy-'-(2-hydroxy-3-methoxybenzylidene)benzohydrazide) were synthesized and characterized structurally and magnetically. Complex 1 contains a triangular Dy core in which the three Dy ions share a μ-OH anion and the deprotonated ligands of (HL-1) serve both capping and bridging functions, while 2 displays a centrosymmetric hexanuclear Dy structure with two similar Dy triangular cores ligated by two fully deprotonated (L-2) ligands, each of which shares two μ-OH anions. All the Dy ions are eight-coordinated with quasi or symmetry.
