Simulating diffraction photographs based on molecular dynamics trajectories of a protein crystal: a new option to examine structure-solving strategies in protein crystallography

A molecular-dynamics-based pipeline has been designed and implemented to emulate the entire process of collecting diffraction photographs and calculating crystallographic structures of proteins from them. The developed methodology should find a range of applications, such as optimizing refinement protocols to solve crystal structures and extracting dynamics information from diffraction data or diffuse scattering.
Analysis of Risk Factors of Potentially Difficult Endotracheal Intubation: A Retrospective Observational Study of 154 Patients with Scoliosis at a Single Center in China

Background Glottic entrance stenosis is an important cause of difficult airway intubation and may be potentially associated with scoliosis. This retrospective study from a single center in China aimed to investigate the parameters and risk factors associated with glottic entrance stenosis by evaluating 154 patients with scoliosis who underwent posterior surgical correction, internal fixation, and fusion. Material/Methods A total of 161 patients diagnosed with scoliosis from 2018 to 2020 were included and grouped by classification, and 7 of them were excluded from the risk factor analysis. All patients underwent posterior surgical correction, internal fixation, and fusion. Basic data, scoliosis-related information, and radiological image were collected. Sagittal and transverse diameter and cross-section area were measured. A new definition of glottic entrance stenosis was proposed based on the traditional formula for prediction of tracheal tuba diameter. Results The percentage of transverse stenosis in these patients was 35.4%, and the incidence of sagittal stenosis and area stenosis were 9.9% and 12.4% respectively, while 37.9% of scoliosis patients also have at least 1 type of glottic entrance stenosis. Longer course of disease is a proven risk factor for sagittal stenosis (P=0.037). Smaller lumbar lordosis indicates higher risk of transverse stenosis (P=0.024). Wedged vertebrae are a risk factor for area stenosis (P=0.024). Conclusions This study comprehensively measured glottic entrance parameters in patients with scoliosis, proposed a new definition of glottic entrance stenosis, and found that longer course of disease, smaller lumbar lordosis, and wedged vertebrae were risk factors for sagittal stenosis, transverse stenosis, and area stenosis, respectively.
Enhanced Biogeochemical Cycling Along the U.S. West Coast Shelf

Continental margins play an essential role in global ocean biogeochemistry and the carbon cycle; however, global assessments of this role remain highly uncertain. This uncertainty arises from the large variability over a broad range of temporal and spatial scales of the processes that characterize these environments. High‐resolution simulations with ocean biogeochemical models have emerged as essential tools to advance biogeochemical assessments at regional scales. Here, we examine the processes and balances for carbon, oxygen, and nitrogen cycles along the U.S. West Coast in an 11‐year hindcast simulation with a submesoscale‐permitting oceanic circulation coupled to a biogeochemical model. We describe and quantify the biogeochemical cycles on the continental shelf, and their connection to the broader regional context encompassing the California Current System. On the shelf, coastal and wind stress curl upwelling drive a vigorous overturning circulation that supports biogeochemical rates and fluxes that are approximately twice as large as offshore. Exchanges with the proximate sediments, submesoscale shelf currents, bottom boundary layer transport, and intensified cross‐shelf export of shelf‐produced materials further impact coastal and open‐ocean balances. While regional variability prevents extrapolation of our results to global margins, our approach provides a powerful tool to identify the dominant dynamics in different shelf setting and quantify their large‐scale consequences.
Contrastive learning–based structure preserving projection for hyperspectral images

ABSTRACT Unsupervised feature extraction methods have been widely applied to remove the huge amount of redundancy in hyperspectral images due to their effectiveness when the label information of samples is unreachable. However, because of the lack of label information, unsupervised feature extraction methods are deficient in the discriminant ability compared to supervised methods. When the number of samples is small, the effect of dimension reduction is usually not good enough. To address the problems, an unsupervised structure preserving projection method named contrastive learning based sparsity preserving projection (CL-SPP) is proposed in this paper. Firstly, CL-SPP increases the discriminant ability of samples by introducing the concept of positive and negative pairs, and adjusts the number of positive and negative pairs in the training set through a parameter. Then, by minimizing the contrastive loss function, CL-SPP makes the positive pairs more similar and the negative pairs less similar after projection. Moreover, the proposed contrastive learning-based method is also extended to the supervised case, as well as a general graph embedding model framework based on comparative learning. Experiments on three hyperspectral images demonstrate that the proposed methods have a better performance than related approaches. More impressively, the effect of CL-SPP is comparable to its supervised version.
An experimental analysis of self-Q-switching via stimulated Brillouin scattering in an ytterbium doped fiber laser

An experimental study of self-Q-switching (SQS) in an ytterbium doped fiber laser (YDFL) arranged using a twin-core GTWave assembly is reported. The main mechanisms that initiate, amplify, and limit SQS pulses in amplitude are revealed to be stimulated Brillouin and Raman scattering (SBS/SRS) and Yb3+ amplified spontaneous emission. The parameters featuring SQS oscillation in terms of efficiency and stability of pulsing are found to be intra-cavity loss and feedback strength. An analysis of the YDFL SQS regime’s features—pulsing time series, optical and RF spectra, amplitude and timing jitter—is provided for the two experimental situations: (i) when SQS pulsing stochastically intermits with regular active Q-switching pulses, given by the action of an intra-cavity acousto-optical modulator, and (ii) when a pure SQS mode is intentionally implemented in the YDFL without a modulator. The close relationship of the processes involved and SQS parameters in these two circumstances is demonstrated. Giant pulses with durations of 70–80 ns are shown to be generated at threshold intra-cavity powers of around 250 W (SBS threshold) and limited at approximately 2 kW of peak power (SRS threshold). At SBS-SQS, we show that at high values of intra-cavity loss, and thus reduced feedback, the amplitude and timing jitter values can be reduced to 5% and 7%, respectively.
Electromagnetic Wave Propagation Along a Buried Insulated Wire

Propagation along a thin dielectric coated wire parallel to the interface between two homogeneous halfspaces is considered. The solution accounts for the presence of the interface provided the coating radius is small compared with the distance to the interface. The final results are simplified in form when dealing with long insulated antennas buried in the earth and operating at low frequencies. Some numerical data are provided for a representative set of conditions. It is found that the presence of the airlearth interface will modify the propagation constant; in some cases the attenuation rate may be increased over that for an infinite medium. On considere la propagation le long d'un fil mince recouvert d'un dielectrique et parallele a I'interface de deux demi-espaces homogknes. La solution tient compte de la presence de I'interface la condition que le rayon du revetement soit petit par rapport la distance a I'interface. La formulation des resultats finals se simplifie pour de longues antennes isolees plongees en terre et fonctionnant aux basses frequences. Des resultats numeriques sont fournies pour un ensemble de conditions typiques. On trouve que la presence de I'interface airlterre modifie la constante de propagation; dans certains cas, le taux d'attknuation peut devenir plus grand que dans un milieu infini.

Impedance spectroscopy as a probe for the degradation of organic light-emitting diodes

Impedance spectroscopy is a powerful method for characterizing the electrical properties of materials and their interfaces. In this study we use capacitance measurements to investigate the degradation of electrically aged bottom-emitting organic light-emitting diodes with different polymeric hole injection layers. The devices comprise a heterojunction between a hole transporting triphenyl-diamine and an electron transporting and green emitting aluminum chelate complex [Alq3, tris-(8-hydroxyquinoline) aluminum]. A detailed analysis of the capacitance as function of frequency and dc bias yields information about trapped and interfacial charges as well as the dynamics of injected charges. We find that the loss of luminance and the increase in drive voltage of stressed devices is accompanied by a deterioration of hole injection and the formation of positively charged quenching centers at or close to the organic heterojunction. Using a new polymeric hole injection layer leads to improved device stability.
Kano: Efficient Cloud Native Network Policy Verification

Cloud-native computing has become a prevailing paradigm with lightweight runtime-level isolation and fast delivery for scalable applications. Cloud-native network policies (CNNPs) are used to realize network isolation with respect to security and availability. Due to the dynamic environment, CNNPs are label-based instead of IP-based and take the form of attribute-based access control (ABAC) to obtain good expressivity. To ensure the correctness of network isolation, CNNP verification is an essential but challenging problem given the large scale and frequent updates of cloud-native environments and the operation automation demand. Thus, we design Kano, an efficient, i.e., easy-to-use and fast-to-execute, system for verifying large scale CNNPs at runtime. Kano is operation-friendly, with a proposed intent-based verification language. A bit matrix model with a prefiltration algorithm and a partial-update method is proposed to support fast complete and incremental verification. Kano also generates fix plans for violations to assist operators. Kano is implemented as a CNNP verification system that is used in ABAC cloud-native platforms and is integrated into the popular Kubernetes orchestrator. An evaluation on a large scale network of 100k nodes and about 68k policies shows the efficiency of Kano, with 12.51 seconds for all reachable invariant verification and 0.299 milliseconds for policy addition verification.
Dynamic Changes in Disney Stock Return under the Uncertain Situation

As the Federal Reserve raises the key interest rate, the exchange rate and the financial market will change. This paper studies how exchange rate change will influence one of the largest entertainment companies’ stock returns. This paper builds VAR model and ARMA-GARCH model to show the influence and finds that the stock return will increase in the short term but significantly shows fluctuations in response to exchange rate changes. So, the paper gives some suggestions for this discovery. The policymakers of the central bank should treat the volatility seriously and think carefully about adjusting the interest rate and the Disney company should create more good products to attract consumers and investors to keep the increase of the return and avoid loss of revenues because of exchange rate changes and fluctuation of the stock return. Investors should also treat the changes in money and financial markets carefully to avoid losses. This research provides some methods to predict the stock return in the future and find the influence of several variables, which can be used in many areas.
Future Diamond UV Imagers For Solar Physics

Despite their steady improvement over the last decades, the UV imaging detectors exhibit some limitations ± inherent to their silicon technology ± that become critical in the context of space missions where the highest spatial resolution, temporal cadence, and photometric accuracy are required. The use of diamond imagers would allow to overcome many of the drawbacks, opening new perspectives in particular for solar observations. It will also make the instruments cheaper. As for projects like the Solar Probe of NASA or the Solar Orbiter of ESA, the case for diamond UV detectors is even stronger, since these missions approach very near to the Sun where the temperature and the radiation fluxes are extremely high. These are the main motivations behind the new R&T programme approved by the French space agency (CNES) in August 1999 which is dedicated to demonstrate the feasability of UV imagers made of semiconducting diamond. In this paper, we report on recent experiments led at the Super-ACO synchrotron facility of LURE in the 150 to 600 eV photon energy range in order to address the influence of surface effects and electrode geometries on the detector behaviour. Quantum Efficiency (QE) values as high as 20% have been measured on prototype detectors over the investigated energy range.
Analisis Infektivitas Simian-Human Immunodeficiency Virus pada Peripheral Blood Mononuclear Cell Macaca fascicularis dan M. nemestrina Secara In Vitro

Development of human immunodeficiency virus type 1 (HIV-1) vaccines and anti-retroviral treatmentis currently hindered by the lack of models representing prominent symptoms of HIV-1 infections seen in humans. Simian-human immunodeficiency virus (SHIV) was constructed to resolve the limitations of SIVmac model and has been used in nonhuman primate model ofviral infections, particularly infections by the close relatives of HIV-1. Macaca fascicularis and M. nemestrina are being developed as model HIV/AIDS, by using chimeric virus SHIV produced by replacing the nucleotide structure of cyclophilin A binding region, vif gene and nef of HIV-1 with cyclophilin A binding region, vif gene and nef from SIV. The research aims to study the model of HIV/AIDS on nonhuman primates PBMC in vitro using SHIV. In particular, the study aims to obtain information about the capability of SHIV replication in PBMC of M. fascicularis and M. nemestrina. Results showed a cytopathic effect (CPE) in the form of multinucleated giant cells and expression of p24 protein in PHA-stimulated PBMC cultures of M. fascicularis and M. nemestrina after SHIV infection. The conclusion of this study is that SHIV can infect PBMC M. fascicularis and M. nemestrina in vitro based on CPE and expression of p24 protein.
Recruitment of TRIM33 to cell‐context specific PML nuclear bodies regulates nodal signaling in mESCs

TRIM33 is a chromatin reader required for mammalian mesendoderm differentiation after activation of Nodal signaling, while its role in mESCs is still elusive. Here, we report that TRIM33 co‐localizes with promyelocytic leukemia nuclear bodies (PML‐NBs) specifically in mESCs, to mediate Nodal signaling‐directed transcription of Lefty1/2. We show that TRIM33 puncta formation in mESCs depends on PML and on specific assembly of PML‐NBs. Moreover, TRIM33 and PML co‐regulate Lefty1/2 expression in mESCs, with both PML protein and formation of mESCs‐specific PML‐NBs being required for TRIM33 recruitment to these loci, and PML‐NBs directly associating with the Lefty1/2 loci. Finally, a TurboID proximity‐labeling experiment confirmed that TRIM33 is highly enriched only in mESCs‐specific PML‐NBs. Thus, our study supports a model in which TRIM33 condensates regulate Nodal signaling‐directed transcription in mESCs and shows that PML‐NBs can recruit distinct sets of client proteins in a cell‐context‐dependent manner.
Efficient removal of phosphorus by adsorption

Abstract The release of excessive amounts of phosphorus into water bodies causes growth of algae, eutrophication, death of fish and plants, reduction in water quality, depletion of dissolved oxygen, and other serious environmental problems. Technology with high-efficiency treatments is used to alleviate eutrophication in aquatic ecosystems caused by the release of excessive amounts of phosphorus. Amongst the chemical, physical and biological methods used for removing phosphates from water, adsorption technology has proven to be effective even at low concentrations. Even though different adsorbents have been developed with excellent properties, many shortcomings were observed. The first aim of this review is to provide facts on novel adsorbents (including biochar, carbonaceous adsorbent, zeolites, calcium silicate hydrate, and metal oxides) used for phosphate removal. Second, various adsorbents applied for phosphate removal have been compared. Third, based on the aforementioned criteria, the best adsorbents are proposed and this is the key novelty of this review work. Moreover, future aspects and challenges regarding nitrate and phosphate removal are presented. Graphical Abstract
Functional and Taxonomic Traits of the Gut Microbiota in Type 1 Diabetes Children at the Onset: A Metaproteomic Study

Type 1 diabetes (T1D) is a chronic autoimmune metabolic disorder with onset in pediatric/adolescent age, characterized by insufficient insulin production, due to a progressive destruction of pancreatic β-cells. Evidence on the correlation between the human gut microbiota (GM) composition and T1D insurgence has been recently reported. In particular, 16S rRNA-based metagenomics has been intensively employed in the last decade in a number of investigations focused on GM representation in relation to a pre-disease state or to a response to clinical treatments. On the other hand, few works have been published using alternative functional omics, which is more suitable to provide a different interpretation of such a relationship. In this work, we pursued a comprehensive metaproteomic investigation on T1D children compared with a group of siblings (SIBL) and a reference control group (CTRL) composed of aged matched healthy subjects, with the aim of finding features in the T1D patients’ GM to be related with the onset of the disease. Modulated metaproteins were found either by comparing T1D with CTRL and SIBL or by stratifying T1D by insulin need (IN), as a proxy of β-cells damage, showing some functional and taxonomic traits of the GM, possibly related to the disease onset at different stages of severity.
Development of a Real-Time Knee Extension Monitoring and Rehabilitation System: Range of Motion and Surface EMG Measurement and Evaluation

In this paper, a real-time knee extension monitoring and rehabilitation system for people, such as patients, the elderly, athletes, etc., is developed and tested. The proposed system has three major functions. The first function is two-channel surface electromyography (EMG) signal measurement and processing for the vastus lateralis (VL) and vastus medialis (VM) muscles using a developed EMG device set. The second function is the knee extension range of motion (ROM) measurement using an angle sensor device set (i.e., accelerometer sensor). Both functions are connected and parallelly processed by the NI-myRIO embedded device. Finally, the third function is the graphical user interface (GUI) using LabVIEW, where the knee rehabilitation program can be defined and flexibly set, as recommended by physical therapists and physicians. Experimental results obtained from six healthy subjects demonstrated that the proposed system can efficiently work with real-time response. It can support multiple rehabilitation users with data collection, where EMG signals with mean absolute value (MAV) and root mean square value (RMS) results and knee extension ROM data can be automatically measured and recorded based on the defined rehabilitation program. Furthermore, the proposed system is also employed in the hospital for validation and evaluation, where bio-feedback EMG and ROM data from six patients, including (a) knee osteoarthritis, (b) herniated disc, (c) knee ligament injury, (d) ischemic stroke, (e) hemorrhagic stroke, and (f) Parkinson are obtained. Such data are also collected for one month for tracking, evaluation, and treatment. With our proposed system, results indicate that the rehabilitation people can practice themselves and know their rehabilitation progress during the time of testing. The system can also evaluate (as a primary treatment) whether the therapy training is successful or not, while experts can simultaneously review the progress and set the optimal treatment program in response to the rehabilitation users. This technology can also be integrated as a part of the Internet of Things (IoT) and smart healthcare systems.
