Particle swarm optimization for a variational quantum eigensolver.

In the field of finding ground and excited states, where quantum computation holds significant promise, using a variational quantum eigensolver (VQE) is a typical approach. However, the success of this approach is vulnerable to two factors: classical optimization for the ansätz parameters and noise from quantum devices. To address these challenges, we adopted particle swarm optimization (PSO) based on swarm intelligence for VQE and presented its performance.

Factors affecting do-not-attempt-resuscitation (DNAR) decisions among adult patients in the emergency department of a general tertiary teaching hospital in China: a retrospective observational study.

Objective: Do-not-attempt-resuscitation (DNAR) orders are designed to allow patients to opt out of receiving cardiopulmonary resuscitation in the event of a cardiac arrest. While DNAR has become a standard component of medical care, there is limited research available specifically focusing on DNAR orders in the context of emergency departments in China. This study aimed to fill that gap by examining the factors related to DNAR orders among patients in the emergency department of a general tertiary teaching hospital in China.

Collagen changes in rabbit conjunctiva after conjunctival crosslinking.

This study aims to determine the ultrastructural changes in collagen fibrils in rabbit conjunctiva after conjunctival crosslinking using riboflavin and ultraviolet A (UVA) light at an irradiation intensity of 45 mW/cm. Conjunctival crosslinking may increase conjunctival stiffness. The supertemporal quadrants of the right eyes of 24 adult rabbits were treated with a topical riboflavin solution (0.

Visual analysis of image-guided radiation therapy based on bibliometrics: A review.

Radiation therapy plays an important role in tumor treatment. The development of image-guided radiation therapy (IGRT) technology provides a strong guarantee for precise radiation therapy of tumors. However, bibliometric studies on IGRT research have rarely been reported.

A unified framework of transformations based on the Jordan-Wigner transformation.

Quantum simulation of chemical Hamiltonians enables the efficient calculation of chemical properties. Mapping is one of the essential steps in simulating fermionic systems on quantum computers. In this work, a unified framework of transformations mapping fermionic systems to qubit systems is presented and many existing transformations-such as Jordan-Wigner, Bravyi-Kitaev, and parity transformations-are included in this framework.

Parallel subgenome structure and divergent expression evolution of allo-tetraploid common carp and goldfish.

How two subgenomes in allo-tetraploids adapt to coexistence and coordinate through structure and expression evolution requires extensive studies. In the present study, we report an improved genome assembly of allo-tetraploid common carp, an updated genome annotation of allo-tetraploid goldfish and the chromosome-scale assemblies of a progenitor-like diploid Puntius tetrazona and an outgroup diploid Paracanthobrama guichenoti. Parallel subgenome structure evolution in the allo-tetraploids was featured with equivalent chromosome components, higher protein identities, similar transposon divergence and contents, homoeologous exchanges, better synteny level, strong sequence compensation and symmetric purifying selection.

The associations between the contents of different PUFAs and the polymorphisms of and have not been studied.

Prognostic Model to Predict Overall Survival for Metastatic Non-Small Cell Lung Cancer Patients Treated With Chemotherapy Combined With Concurrent Radiation Therapy to the Primary Tumor: Analysis From Two Prospective Studies.

Purpose: The role of radiotherapy, in addition to chemotherapy, has not been thoroughly determined in metastatic non-small cell lung cancer (NSCLC). The purpose of the study was to investigate the prognostic factors and to establish a model for the prediction of overall survival (OS) in metastatic NSCLC patients who received chemotherapy combined with the radiation therapy to the primary tumor.

Methods: The study retrospectively reviewed 243 patients with metastatic NSCLC in two prospective studies.

Mid-term results of total hip arthroplasty with modified trochanteric osteotomy in Crowe type IV developmental dysplasia of the hip.

Background: This study aimed to explore mid-term clinical results of cementless total hip arthroplasty (THA) with modified trochanteric osteotomy in Crowe type IV developmental dysplasia of the hip (DDH).

Methods: Thirteen patients (13 hips) with Crowe type IV DDH who underwent THA with modified trochanteric osteotomy between May 2013 and October 2015 were retrospectively analyzed. The mean follow-up duration was 5.

The results of screw augmentation of acetabular cement spacers for the treatment of periprosthetic hip joint infection.

Introduction: Prosthesis of antibiotic-loaded acrylic cement (PROSTALAC) is widely used in two-stage revision arthroplasty in periprosthetic joint infection (PJI) after total hip arthroplasty (THA). In our institution, we encountered several cases of acetabular cement spacer dislodgement. The aim of this study was to compare the results of two-stage revision arthroplasties with antibiotic-loaded cement spacers with or without screws on the acetabulum for PJI.

Simultaneous integrated boost of intensity-modulated radiation therapy to Stage II-III non-small cell lung cancer with metastatic lymph nodes.

Local tumor failure remains a major problem after radiation-based nonsurgical treatment for unresectable locally advanced nonsmall cell lung cancer (NSCLC）and inoperable stage II NSCLC. The aim of this study was to evaluate the feasibility of simultaneous integrated boost of intensity-modulated radiation therapy (SIB-IMRT) to stage II-III NSCLC with metastatic lymph nodes (ChiCTR 2000029304). Patients were diagnosed by pathology or PET-CT.

[Distribution Characteristics of Disinfection By-Products and the Effects of Booster Chlorination in Long-Distance Water Supply Systems].

It is difficult for waterworks that add chlorine into finished water once to maintain sufficient residual chlorine at unfavorable points of the pipe network that supply water for large areas of coverage. Therefore, booster chlorination was employed for a long-distance water distribution system. The study was performed in H City with a water supply system serving about 400 km of downtown and rural areas.

[Distribution of Four Artificial Sweeteners in Water Treatment and Water Supply System in City H of Zhejiang Province].

Taking the sewage and drinking water treatment system of two cities in Zhejiang Province as the main research target, a systematic investigation on the common artificial sweeteners was carried out by solid phase extraction-high performance liquid chromatography (SPE-HPLC). The results showed that SPE-HPLC can accurately determine micro acesulfame (ACE), saccharin (SAC), aspartame (ASP), and neotame (NEO) in water. The detection limits were 57, 120, 170, and 47 μg·L, and the quantification limits were 190, 400, 567, and 157 μg·L, respectively.

The occurrence of 18 types of disinfection by-products (DBPs) in two waterworks and the corresponding water supply networks of H City in Zhejiang Province was determined by gas chromatography coupled with electron capture detector (GC-ECD). The correlation between DBPs and organic precursors, and health risks caused by DBPs, were discussed. Results showed that the disinfection by-products detected in drinking water in H City mainly include trihalomethanes (THMs), haloacetic acid (HAAs), haloacetonitrile (HANs) and trichloronitromethane (HNMs), with highest concentrations of THMs followed by HAAs.

Randomized phase II study of pemetrexed-cisplatin or docetaxel-cisplatin plus thoracic intensity-modulated radiation therapy in patients with stage IV lung adenocarcinoma.

Systemic chemotherapy is the standard treatment modality for stage IV lung adenocarcinoma patients with EGFR wild-type or unknown mutation status. Recent years, there is increasing evidence showed that selected patients with stage IV disease could benefit from aggressive thoracic radiotherapy. Either pemetrexed or docetaxel, combined with cisplatin, can be used for patients with stage IV lung adenocarcinoma.

Quercetin is the Active Component of Yang-Yin-Qing-Fei-Tang to Induce Apoptosis in Non-Small Cell Lung Cancer.

Yang-Yin-Qing-Fei-Tang (YYQFT) is a well-known traditional Chinese medicine used in the treatment of chronic obstructive pulmonary emphysema, bronchitis, cytomegaloviral pneumonia, but the mechanisms of the medicine are not clear. This study aimed to identify the active components of YYQFT and elucidate the underlying mechanism on non-small cell lung cancer.
