- Abstract
The Neuroscience Monoclonal Antibody Sequencing Initiative (NeuroMabSeq) is a concerted effort to determine and make publicly available hybridoma-derived sequences of monoclonal antibodies (mAbs) valuable to neuroscience research. Over 30 years of research and development efforts including those at the UC Davis/NIH NeuroMab Facility have resulted in the generation of a large collection of mouse mAbs validated for neuroscience research. To enhance dissemination and increase the utility of this valuable resource, we applied a high-throughput DNA sequencing approach to determine immunoglobulin heavy and light chain variable domain sequences from source hybridoma cells. The resultant set of sequences was made publicly available as a searchable DNA sequence database (neuromabseq.ucdavis.edu) for sharing, analysis and use in downstream applications. We enhanced the utility, transparency, and reproducibility of the existing mAb collection by using these sequences to develop recombinant mAbs. This enabled their subsequent engineering into alternate forms with distinct utility, including alternate modes of detection in multiplexed labeling, and as miniaturized single chain variable fragments or scFvs. The NeuroMabSeq website and database and the corresponding recombinant antibody collection together serve as a public DNA sequence repository of mouse mAb heavy and light chain variable domain sequences and as an open resource for enhancing dissemination and utility of this valuable collection of validated mAbs.

The millisecond pulsar(MSP) is believed to be an old neutron star(NS) having undergone spin-up by the accreting material from the donor. Whereas, the discovery of eccentric millisecond pulsars (eMSPs) in the Galactic field challenges such a scenario producing MSP-white dwarf (WD) only in the circular orbit. As orbital periods and companion mass of these eMSPs are located in a narrow range, a reasonable postulation is that they have the same origin. Although many models have been proposed to interpret their origin, however, the origin of the narrow range of the orbital period is still an open question. The accretion-induced collapse(AIC) of the ONe WD is considered to be an important pathway to form MSP, which was expected to result in the formation of MSP in the circular orbit due to tidal circularization. Here we revisited this scenario by the binary population synthesis including the specific circularization calculation. Our results indicate that binaries with insufficient circularization in this scenario can evolve into the eMSPs. The narrow initial binary parameters required by insufficient circularization can naturally account for the narrow range of the orbital period. Although the evolution of WD's AIC process has not been well understood, the characteristic of a narrow range in the orbital period of eMSPs can still set constraints on the physics of their evolution., Comment: accepted by MNRAS

The optimal treatment for stable angina patients with severe coronary artery stenosis remains unclear. This study aimed to compare interventional therapy with exercise rehabilitation in this population.Methods: Fifty stable angina patients with severe coronary stenosis who underwent stent implantation were included in the optimal medical therapy (OMT) plus percutaneous coronary intervention (PCI) group, and 50 patients who did not undergo interventional treatment were included in OMT plus CR group receiving exercise rehabilitation guidance for one year. Cardiovascular composite endpoint events, cardiopulmonary fitness, and quality of life scale scores were assessed after one year.Results: No significant difference in incidence of cardiovascular composite endpoint events was observed between OMT plus PCI group with OMT plus CR group (20.0% vs 14.6%) after one year. Cardiopulmonary fitness represented as peak VO2 (19.2± 3.5 vs 17.6± 3.2 mL/kg/min), peak load (120± 19 vs 108± 20 W), and AT (13.5± 1.5 vs 12.1± 1.3 mL/kg/min) were significantly higher in the rehabilitation group than the intervention group after one year. Both groups showed improvement in their quality of life, but the rehabilitation group improved in more scales.Conclusion: Interventional therapy did not reduce cardiovascular events compared to exercise-based rehabilitation in stable angina patients with severe coronary artery stenosis, but the rehabilitation can improve cardiovascular fitness and quality of life more.Keywords: cardiac rehabilitation, stable angina, percutaneous coronary intervention, cardiopulmonary fitness

Stigma remains a formidable barrier for women living with HIV/AIDS, hindering their access to healthcare and exacerbating health disparities. Indeed, some women living with HIV/AIDS can successfully confront and overcome stigma. There remains a paucity of qualitative research exploring the stigma coping strategies of women living with HIV/AIDS in China. This study was aimed to gain the deeper understanding of stigma experienced by women living with HIV/AIDS and coping strategies.Patients and Methods: We recruited diverse participants using snowball sampling and purposive sampling. Semi-structured personal in-depth interviews were conducted with 30 women living with HIV/AIDS from December 2022 to June 2023. The samples were from four HIV/AIDS designated hospitals. The data were analyzed using the Colaizzi seven-step model.Results: The experiences of stigma among women living with HIV/AIDS included family role (wife/mother/grandmother) collapse and disgusted by family, resignation in being shunned by others, helplessness due to social exclusion, grief at being devaluated, and resentment for experiencing injustice. The coping strategies used to deal with stigma included concealing their conditions, avoiding socialization, and attempting to retaliate against society.Conclusion: Healthcare professionals are recommended to offer women living with HIV/AIDS effective emotional support and guidance to cope with stigma. The study highlights the stigma they face, providing valuable evidence for policymakers. Recommendations emphasize the importance of developing services addressing both physical and psychological needs of women living with HIV/AIDS.Keywords: female, acquired immunodeficiency syndrome, social stigma, Asian, qualitative research

Astrophysics - High Energy Astrophysical Phenomena ,Astrophysics - Solar and Stellar Astrophysics - Abstract
The post-Keplerian(PK) parameters inferred from pulsar timing provide a convenient way to test Einstein's general theory of relativity. However, before obtaining a pure orbital decay $\dot{P}_b$ induced by gravitational wave radiation, which is one of the PK parameters, a number of factors need to be accounted for carefully. The effect of tidal dissipation on $\dot{P}_b$ has been thought of as negligible. Here, we investigate the data for possible effects of tidal dissipation on $\dot{P}_b$. The possibility of the tidal dissipation as a contributor to $\dot{P}_b$ in a large sample of millisecond pulsar binaries is investigated in detail. We collected a large sample of pulsar binaries with measured $\dot{P}_b$. All of the systems are millisecond pulsars. The residual $\dot{P}^{Res}_b$ of these systems was obtained by subtracting the three normal effects, that is to say the effect of Shklovskii, line-of-sight acceleration, and gravitational radiation. Assuming that tidal dissipation is responsible for such a residual $\dot{P}^{Res}_b$, the tidal parameters of these systems can be calculated and compared with the tidal models. The residual $\dot{P}^{Res}_b$ is distributed over the half positive and half negative. The dynamical tidal model can explain the residual $\dot{P}_b$ of millisecond pulsar-white dwarf binaries. And the Love number of the main-sequence companion of \object{PSR J1227-4853} can be derived as a reasonable value $k_2=0.177^{+0.098}_{-0.058}$ with the equilibrium tidal model. Those results are compatible with the scenario of tidal dissipation. Additionally, a weak correlation between the tidal parameter and orbital period is revealed, likely originating in the tidal process of the recycled stage which is worthy of further investigation.

Astrophysics - High Energy Astrophysical Phenomena - Abstract
In this study, we report on a detailed single pulse analysis of the radio emission from a rotating radio transient (RRAT) J1918$-$0449 which is the first RRAT discovered with the five hundred meter aperture spherical radio telescope (FAST). The sensitive observations were carried out on 30 April 2021 using the FAST with a central frequency of 1250 MHz and a short time resolution of 49.152 $\mu$s, which forms a reliable basis to probe single pulse emission properties in detail. The source was successively observed for around 2 hours. A total of 83 dispersed bursts with significance above 6$\sigma$ are detected over 1.8 hours. The source's DM and rotational period are determined to be 116.1$\pm$0.4 \pcm \ and 2479.21$\pm$0.03 ms, respectively. The share of registered pulses from the total number of observed period is 3.12\%. No underlying emission is detected in the averaged off pulse profile. For bursts with fluence larger than 10 Jy ms, the pulse energy follows a power-law distribution with an index of $-3.1\pm0.4$, suggesting the existence of bright pulse emission. We find that the distribution of time between subsequent pulses is consistent with a stationary Poisson process and find no evidence of clustering over the 1.8 h observations, giving a mean burst rate of one burst every 66 s. Close inspection of the detected bright pulses reveals that 21 pulses exhibit well-defined quasi-periodicities. The subpulse drifting is present in non-successive rotations with periodicity of $2.51\pm0.06$ periods. Finally, possible physical mechanisms are discussed., Comment: 11 pages, 11 figures

The understanding of the impact of FLT3 mutations on treatment decisions is limited.Methods: In this retrospective, observational study, we investigated the key epidemiological characteristics, treatment patterns and responses among adult patients with newly diagnosed (ND) AML in China, who initiated treatment from January 1, 2015, to December 31, 2019, or progressed to relapsed/refractory (R/R) AML by December 31, 2020.Results: Of the 853 ND AML patients included, 63.4% were screened for FLT3 status, and 20.1% tested positive (FLT3MUT) at initial diagnosis. Of 289 patients who progressed to R/R AML during the study period, 24.9% were screened at the diagnosis of R/R AML, and 19.4% tested positive; 20.5% of screened patients changed FLT3 status at first diagnosis of R/R AML. Initial treatment regimens or treatment responses did not seem to differ in patients with ND AML by FLT3 mutation status. In patients with R/R AML, there was an apparent difference in second-line treatment choices by FLT3 mutation status; however, the number of FLT3-mutated patients were limited to demonstrate any meaningful distinction. FLT3-mutated R/R AML was associated with shorter relapse time.Conclusion: Study findings showed that there was a lack of routine testing for FLT3 mutations at first diagnosis of R/R AML, and initial treatment decisions did not differ by FLT3 mutation status. Given the clinical burden of FLT3MUT, likelihood of FLT3 status changes, and emerging FLT3 inhibitors, further routine FLT3 screening is needed to optimize treatment of R/R AML.

Recently, a new study has explored and defined the AFP serological response and used it to explain the subclass of intermediate-stage hepatocellular carcinoma (IM-HCC) with “sharp-falling” AFP change after transarterial chemoembolization (TACE). It may be a new and simple tool for assessing the prognosis of patients. This study aims to explore a simplified AFP trajectory and its impact on overall survival (OS) and disease-free survival (DFS) for IM-HCC after hepatectomy.Patients and Methods: Between January 2007 and May 2012, data from the Sun Yat-sen University Cancer Center was examined in this longitudinal, retrospective cohort study. A generalized additive model was applied to distinguish potential AFP dynamic trajectories. The Kaplan-Meier method was applied to analyze OS and DFS, and multivariate Cox models were used to calculate adjusted hazard ratios (aHRs) and 95% CIs for overall survival.Results: 144 patients who had IM-HCC with at least three AFP repeat measurements were included in the study. Three similar trajectories are displayed using the generalized additive model: low-stable (35.4%; n = 51), high-rising (36.1%; n = 52), and sharp-falling (28.5%; n = 41). Compared with the low-stable class, the aHRs for death were 2.84 (1.50, 5.41) and 0.59 (0.25, 1.40) for the high-rising and sharp-falling classes, adjusted by age and log AFP. Simplified AFP trajectory had higher relative importance than sex, intrahepatic tumor number, Child-Pugh class, and baseline AFP.Conclusion: The simplified AFP trajectory is a promising biomarker for IM-HCC patients undergoing hepatectomy. In the future, it should be verified by a larger population containing various stages of HCC.Keywords: hepatocellular carcinoma, hepatectomy, AFP trajectory, AFP serological response, overall survival

This study identifies potential biomarkers of KTCN based on the characterization of autophagy-related genes (ARGs) and the construction of a diagnostic model; and explores their relevance to immune infiltrating cells in KTCN.Methods: Gene Expression Omnibus (GEO) data were downloaded and ARGs were acquired from GeneCards and Molecular Signatures Database (MSigDB). Autophagy-related differential expression genes (ARDEGs) were discovered through the integration of differentially expressed genes (DEGs) with ARGs, while hub genes of KTCN were discovered by protein-protein interaction (PPI) network analysis. The probable biological roles of these hub ARDEGs were examined using functional enrichment analysis, and a KTCN diagnostic model was generated using the least absolute shrinkage and selection operator (LASSO) regression analysis. We also employed the CIBERSORTx and ssGSEA algorithms to identify potential regulatory pathways to compare the abundance of immune cell infiltrates and their association with hub genes. Finally, the hub gene expression levels were confirmed using validation datasets as well as blood samples from KTCN and healthy individuals.Results: In this study, we identified 12 hub ARDEGs, of which 9 genes were substantially distinct between KTCN patients and normal groups. The LASSO risk score was used to generate the nomogram, and the calibration curve evaluated the model’s effective diagnostic performance (C index of 0.961). Patients with KTCN had greater percentages of M2 Macrophages and Gamma delta T cells, according to CIBERSORTx and ssGSEA. The outcomes of the bioinformatics analysis were supported by the DDIT3 and BINP3 expression levels in KTCN patients and healthy controls, according to the qRT-PCR data.Conclusion: Five biomarkers (CFTR, PLIN2, DDIT3, BAG3, and BNIP3) and diagnostic models offer fresh perspectives on identifying and managing KTCN.Keywords: keratoconus, autophagy-related genes, diagnostic model, biomarker, immune infiltration, bioinformatics analysis

However, predicting the survival of HCC patients receiving TACE remains challenging.Methods: In this retrospective study, we analyzed a total of 1805 HCC patients who received TACE. The patients were randomly divided into a training set (n = 1264) and a validation set (n = 541). We examined various prognostic factors within the training set and developed a simple ALFP (ALBI grade, AFP, and Prothrombin time) score, which was subsequently validated using the independent validation set.Results: Our multivariate analysis revealed that baseline ALBI grade 2 or 3, AFP ≥ 100 ng/mL, and PT > 13.1 s were independent unfavorable prognostic factors for HCC patients receiving TACE (p 13.1 s. The score has a range of 0 to 3, and higher scores are associated with poorer outcomes.

To better characterize the inflammatory response during neonatal sepsis, we compared the differences in serum cytokines and chemokines between full-term neonates with sepsis and without infection.Methods: We enrolled 40 full-term neonates with sepsis and 26 full-term neonates without infection as controls between October 2016 and June 2018. Forty cytokines /chemokines in serum were analyzed using the Luminex Bead Immunoassay System.Results: Our results showed that serum IL-6, IL-8, TNF-α, IL-1β, MIF, CXCL13, CXCL1, CXCL2, CXCL5, CXCL6, CXCL16, CCL27, CCL2, CCL8, CCL3, CCL20, CCL23, and CX3CL1 levels were significantly increased in neonates with sepsis compared to those in the control group (all p< 0.05). The levels of serum CCL20, and IL-17 were higher in late-onset sepsis (LOS) than those in early-onset sepsis (EOS) (all p< 0.05). Conversely, serum CXCL16 was lower in LOS than that in EOS (p< 0.05).Conclusion: Our findings revealed that excessive pro-inflammatory cytokines might be involved in neonatal sepsis. In addition, chemokines significantly increased the recruitment of immune cells after infection to participate in the anti-infection defense of neonates, but this could lead to damage.Keywords: neonatal sepsis, cytokines, chemokines

However, correlations between DLEU2 and kidney renal clear cell carcinoma (KIRC) and liver hepatocellular carcinoma (LIHC) have rarely been reported.Methods: We first analysed the expression of DLEU2 across cancers and the correlation between DLEU2 and the clinical features of KIRC and LIHC by using the “ggplot2” package in R and searched the Oncomine database and Timer website platform. We verified the expression of DLEU2 in the GEO dataset (GSE105261 and GSE45267). Receiver operating characteristic (ROC) curves were drawn using the “pROC” and “ggplot2” packages in R, and we constructed a DLEU2-based prognostic nomogram for KIRC and LIHC by using the “survival” and “rms” packages in R. Then, we analysed the correlation between DLEU2 expression and prognosis in R as well as the correlation between DLEU2 and immune cell infiltration in the TIMER database. Finally, we explored the causes of DLEU2 upregulation in the UCSC Xena and UALCAN databases.Results: We found that DLEU2 was upregulated in many cancers, including KIRC and LIHC. Expression of DLEU2 is associated with tumour stage, grade, lymphatic metastasis, and distant metastasis in KIRC as well as alpha-fetoprotein (AFP), tumour stage, grade, lymphatic metastasis, and distant metastasis in LIHC. DLEU2 is an adverse factor for the prognosis of KIRC and LIHC. In addition, DLEU2 has moderate accuracy in diagnosing KIRC and LIHC and predicting their prognosis. Moreover, we found that expression of DLEU2 correlated positively with immune cell infiltration in KIRC and LIHC, and upregulation of DLEU2 in KIRC and LIHC suggests a poor prognosis based on immune cells analysis. Genetic and epigenetic analyses of DLEU2 indicate that copy number variations (CNVs) and methylation contribute to the upregulation of DLEU2.Conclusion: The long noncoding RNA DLEU2 has the potential to predict the prognosis and immune infiltration of KIRC and LIHC.Keywords: DLEU2, prognosis, immune infiltration, KIRC, LIHC

The aim of the current study was to explore the role of anxiety and depression as a potential mediator between perceived stress and sleep quality among health care workers.Methods: Data were collected through an online survey using the snowball sampling method and comprised 588 current health care workers in Zhejiang and Hubei provinces, China, from February to March 2020. We administered the Sleep Quality Questionnaire (SQQ), the Perceived Stress Scale (PSS-10), the Patient Health Questionnaire (PHQ-4) and the sociodemographic characteristics and COVID-19-related characteristics questionnaire. Structural equation modelling (SEM) was used to examine the direct and indirect relationships between perceived stress, anxiety and depression, and sleep quality.Results: The average scores for sleep quality and perceived stress were 16.01 (95% CI [15.40, 16.57]) and 15.46 (95% CI [15.05, 15.87]), respectively. The positive rates of anxiety and depression symptom tests were 9.86% and 10.37%, respectively. The SEM results indicated that the original relationship between perceived stress and sleep quality was beta = 0.52 (P < 0.001) and reduced to beta = 0.25 (P = 0.045) while introducing anxiety and depression as mediating variables. Perceived stress was positively associated with anxiety and depression (beta = 0.78, P = 0.014), and anxiety and depression were positively associated with sleep quality (beta = 0.42, P < 0.001).Conclusion: Poor sleep quality and high perceived stress were common during the COVID-19 crisis. Reducing perceived stress could help reduce anxiety and depression symptoms, thereby improving sleep quality among health care workers. In an attempt to promote psychological resources, we should perhaps take multiple measures, including personal tailored intervention and organizational humanistic concern.Keywords: health care workers, sleep quality, anxiety, depression, perceived stress, COVID-19

The overall survival is dismal due to the high frequency of recurrence and metastasis after surgery and resistance to chemotherapy. Patients with the locally advanced or metastatic disease usually have the poorest prognosis. Herein, we report a rare highly responsive PDAC with liver metastasis.Case Presentation: A 49-year-old female presented with dull abdominal and back pain, discomfort after eating, fatigue, and recent weight loss of 5 kg. Clinical examination was normal and no relevant oncological history was observed. A routine blood test showed low red blood cell count and low hemoglobin level. Markedly increased carcinoembryonic antigen (CEA) and carbohydrate antigen (CA) 125 levels were detected. Computer tomography (CT) of the abdomen revealed a massive pancreatic tumor with the invasion of almost all important surrounding blood vessels and liver metastasis. After the genetic test and percutaneous biopsy for this tumor, a multidisciplinary team (MDT) discussion was initiated. Subsequently, oral chemotherapy (S-1) and 125I radiative seeds implantation were recommended. Surprisingly, the tumor shrank significantly after treatment. On August 14, 2019, pancreatoduodenectomy was performed. The tumor was successfully resected and liver metastasis was not detected. Based on the postoperative histopathological result, there was only fibrous tissue hyperplasia and inflammatory cell infiltration. Besides, no tumor tissue was found. Until now, through outpatient follow-up, no signs of recurrence and metastasis have been observed.Conclusion: Although the therapeutic efficacy and prognosis of PDAC are dismal, we successfully cured a patient with a metastatic disease through multidisciplinary cooperation. However, the therapeutic experience should be summarized and further research should be performed to confirm whether it is appropriate for other PDAC patients.Keywords: pancreatic ductal adenocarcinoma, metastasis, diagnosis, chemotherapy, multidisciplinary team

Present study aimed to explore the therapeutic effect and specific mechanism(s) of combination BET family protein and HDAC inhibition in chondrosarcoma.Methods: Two chondrosarcoma cells were treated with BET family protein inhibitor (JQ1) and histone deacetylase inhibitors (HDACIs) (vorinostat/SAHA or panobinostat/PANO) separately or in combination; then, the cell viability was determined by Cell Counting Kit-8 (CCK-8) assay, and the combination index (CI) was calculated by the Chou method; cell proliferation was evaluated by 5-ethynyl-2′-deoxyuridine (EdU) incorporation and colony formation assay; cell apoptosis and reactive oxygen species (ROS) level were determined by flow cytometry; protein expressions of caspase-3, Bcl-XL, Bcl-2, γ-H2AX, and RAD51 were examined by Immunoblotting; DNA damage was determined by comet assay; RAD51 and γ-H2AX foci were observed by immunofluorescence.Results: Combined treatment with JQ1 and SAHA or PANO synergistically suppressed the growth and colony formation ability of the chondrosarcoma cells. Combined BET and HDAC inhibition also significantly elevated the ROS level, followed by the activation of cleaved-caspase-3, and the downregulation of Bcl-2 and Bcl-XL. Mechanistically, combination treatment with JQ1 and SAHA caused numerous DNA double-strand breaks (DSBs), as evidenced by the comet assay. The increase in γ-H2AX expression and foci formation also consistently indicated the accumulation of DNA damage upon cotreatment with JQ1 and SAHA. Furthermore, RAD51, a key protein of homologous recombination (HR) DNA repair, was found to be profoundly suppressed. In contrast, ectopic expression of RAD51 partially rescued SW 1353 cell apoptosis by inhibiting the expression of cleaved-caspase-3.Conclusion: Taken together, our results disclose that BET and HDAC inhibition synergistically inhibit cell growth and induce cell apoptosis through a mechanism that involves the suppression of RAD51-related HR DNA repair in chondrosarcoma cells.Keywords: chondrosarcoma, JQ1, HDAC, apoptosis, RAD51, DNA repair

The quasi-periodic feature of 1-10 years exhibited in pulsar timing noise has not been well understood since 1980. The recently demonstrated correlation between timing noise and variation of pulse profile motivates us to further investigate its origins. We suggest that the quasi-periodicity feature of timing noise, with rapid oscillations lying on lower frequency structure, comes from the geodetic precession of an unseen binary system, which induces additional motion of the pulsar spin axis. The resultant change of azimuth and latitude at which the observer's line of sight crosses the emission beam is responsible for the variation of timing noise and pulse profile respectively. The first numerical simulation to both timing noise and pulse profile variation are thus performed, from which the orbital periods of these pulsars are of 1-35 minutes. Considering the existence of the ultracompact binary white dwarf of orbital period of 5.4 minute, HM Cancri, such orbital periods to pulsar binaries are not strange. The change of latitude of the magnetic moment exceeding the range of emission beam of a pulsar results in the intermittency, which explains the behavior of PSR B1931+24. Therefore, it provides not only a mechanism of the quasi-periodic feature displayed on some ``singular" pulsars, like timing noise, variation of pulse profile and intermittency; but also a new approach of searching ultra-compact binaries, possibly pulsar-black hole binary systems., Comment: 6 pages, 4 figures

The sprinkler pivots on a bearing on top of its threaded attachment nut. It is driven in a circular motion by a spring-loaded arm pushed back by the water stream which returns to "impact" the stream. The water stream can thus rotate around a fix axis. Analogously in our universe, the outflow or jet formed by the relativistic plasma corresponds to the water stream of a sprinkler; and the baryons in the tilted outer accretion disc or torus play the role of "impact arm". Then the jet aligning with the inner parts of a warped disc can directly "touch" the outer region of the disc. The resultant collision between such rapid leptons and slow baryons automatically accounts for the main features of broad-line region of active galactic nuclei. Moreover, it naturally provides a channel of dissipating the angular momentum of an accretion disc, which has long been a problem in theory of accretion disc., Comment: 10 pages, 4 figures, and 2 tables

Astrophysics - Astrophysics of Galaxies - Abstract
Short precession periods like 164d of SS433 can be well determined by observations of time scales longer or much longer than the precession period. However, it doesn't work for sources with precession periods of millions of years. This paper utilizes the particular morphologies of X-shaped sources, so that the 3 dimension kinematics of lobes can be obtained. Thus, for the first time, the million-year precession period of X-shaped sources by observer on the Earth can be determined elegantly: $(6.1\pm 1.5)$Myr, $(1.8\pm 0.5)$Myr, and $(3.2\pm 1.2)$Myr for 3C52, 3C223.1 and 4C12.03 respectively. The result naturally explains the asymmetry displayed in the morphology of these sources, and the effect of propagation time on the diversity of morphologies is well demonstrated. The precession period may originate from long-term effects of a binary super-massive black hole system, which is a potential source of gravitational wave radiation., Comment: 19 pages, 4 figures, Accepted to ApJ Letters

Astrophysics - Cosmology and Nongalactic Astrophysics - Abstract
Context. We present evidence that parsec-scale jets in BL Lac objects may be significantly distinct in kinematics from their counterparts in quasars. We argued this previously for the BL lac sources 1803+784 and 0716+714, report here a similar pattern for another well-known BL Lac object, PKS 0735+178, whose nuclear jet is found to exhibit kinematics atypical of quasars. Aims. A detailed study of the jet components' motion reveals that the standard AGN paradigm of apparent superluminal motion does not always describe the kinematics in BL Lac objects. We study 0735+178 here to augment and improve the understanding of the peculiar motions in the jets of BL Lac objects as a class. Methods. We analyzed 15 GHz VLBA (Very Long Baseline Array) observations (2cm/MOJAVE survey) performed at 23 epochs between 1995.27 and 2008.91. Results. We found a drastic structural mode change in the VLBI jet of 0735+178, between 2000.4 and 2001.8 when its twice sharply bent trajectory turned into a linear shape.We further found that this jet had undergone a similar transition sometime between December 1981 and June 1983. A mode change, occurring in the reverse direction (between mid-1992 and mid-1995) has already been reported in the literature. These structural mode changes are found to be reflected in changed kinematical behavior of the nuclear jet, manifested as an apparent superluminal motion and stationarity of the radio knots. In addition, we found the individual mode changes to correlate in time with the maxima in the optical light curve. The last two transitions occurred before a (modest) radio flare. The behavior of this pc-scale jet appears to favor a scenario involving non-ballistic motions of the radio knots, produced by the precession of a continuous jet within the ambient medium., Comment: Accepted for publication in A&A (Abstract reduced for astro-ph)

In this study, researchers conducted an examination of the consequences, both positive and in need of improvement, of a large college of education's student support process (SSP). The SSP was put in place by college of education leaders in order to better support the teacher education students enrolled throughout its teacher education program, through both their coursework and student teaching experiences. Researchers used multiple methods to examine the SSP's purposes and objectives, the SSP's strengths and challenges, and the typical students being served via the SSP (e.g. in terms of demographics, also to understand impacts). Researchers collected and analyzed institutional data as well as data derived via the self-reported perspectives of faculty and staff engaged throughout all stages of the SSP. Findings are offered, as are implications for internal as well as external audiences including but not limited to college of education faculty, staff, and leaders, potentially within and well beyond the United States (US).

Epimedium is a common traditional Chinese herbal medicine that is widely used to relieve POI in China. To systematically explore the pharmacological mechanism of epimedium on POI therapy, a network pharmacology approach was conducted at the molecular level.Methods: In this study, we adopt the network pharmacology method, which mainly includes active ingredients prescreening, target prediction, gene enrichment analysis and network analysis.Results: The network analysis revealed that 6 targets (ESR1, AR, ESR2, KDR, CYP19A1 and ESRRG) might be the therapeutic targets of epimedium on POI. In addition, gene-enrichment analysis suggested that epimedium appeared to play a role in POI by modulating 6 molecular functions, 5 cellular components, 15 biological processes and striking 52 potential targets involved in 13 signaling pathways.Conclusion: This study predicted the pharmacological and molecular mechanism of epimedium against POI from a holistic perspective, as well as provided a powerful tool for exploring pharmacological mechanisms and rational clinical application of traditional Chinese medicine.Keywords: network pharmacology, premature ovarian insufficiency, epimedium, infertility, GO, KEGG

The focus of the present study was to adapt the Self-Compassion Scale (SCS) into Chinese, assess the validity and reliability of the measure and test measurement invariance (MI) across nursing students and medical workers.Methods: The current study assessed the psychometric properties and invariance of the SCS-Short Form (SCS-SF) in two samples of 2676 from nursing students and medical workers. For construct validity, confirmatory and exploratory factor analyses (CFAs and EFAs) were conducted. Using Perceived Stress Questionnaire , Short Form-8 Health Survey (SF-8) and Goldberg Anxiety and Depression Scale, we evaluated concurrent validity and convergent/divergent validity. For reliability, internal consistency and test–retest analysis were employed. Multi-group analyses were conducted to examine MI of the different SCS-models across populations.Results: CFA showed that the proposed six-factor second‐order model could not be replicated and the six-factor first‐order model was a reasonable to mediocre fitting model in both samples. EFA supported a three-factor structure which consisted of one positive and two negative factors. CFA confirmed that the hypothesized three-factor structure with 10 items ultimately was considered as the optimal model on the fitted results. The SCS-SF‐10 (10 items form) also demonstrated acceptable internal consistency and test–retest reliability, as well as strong concurrent validity with measures of stress perception, health status, anxious and depressive symptoms. Convergent/divergent validity was not satisfactory. Multi-group CFAs provided support for the validity of the established models.Conclusion: The Chinese version of the SCS-SF‐10 has sound psychometric properties and can be applied to efficiently assess self-compassion in Chinese-speaking populations. The current study contributes to the identification and measurement of self-compassion after adversities.Keywords: medical workers, nursing students, self-compassion, Chinese, measurement invariance, psychometric assessment

Astrophysics - Abstract
An extreme Kerr black hole (BH) surrounded by a precessing disk is invoked to explain the light curves of gamma-ray bursts (GRBs) based on the coexistence of the Blandford-Znajek (BZ) and the magnetic coupling (MC) processes. The overall shape of the light curves and the duration of GRBs are interpreted by the evolution of the half-opening angle of the magnetic flux on the BH horizon, and the complex temporal structures are modulated by the precession and nutation of the jet powered by the BZ process. The time profile of the emission exhibits a fast rise and a slow decay due to the effect of the evolution of the half-opening angle. The light curves of several GRBs are well fitted by this model with only six free parameters., Comment: 8 pages, 8 figures. Accepted for publication in A&A

An inverse solution strategy using linear element of Boundary Element Method(BEM)was developed, which will become a novel application base to potentially reflect the equivalent mechanical effect around reservoir corresponding to CO2 spreading during its injection process. Firstly, a linear-element BEM code was studied to improve the accuracy in analyzing the connection between induced ground minute deformations and underground inner loading. Secondly, the space regularization was adopted to deal with the ill-posed problem during the optimization to inverse problem solution. The boundary conditions of a near-field structure as active source were reversely figured out in an efficient numerical way based on its passive deformation that was sampled at a few specific positions at far field. Meanwhile, the effectiveness of linear-element BEM in solving inverse problems was demonstrated. Finally, based on the implementation of hydraulic fracturing in a coal seam in Alberta, Canada, the monitored data of its induced surface displacements was input to invert the equivalent internal pressure onto are-opened fracture within reservoir. The results show that the proposed inverse solution workflow and programmed algorithm are applicable to effectively guiding hydraulic fracturing interpretation so as to further facilitating coal bed methane recovery.

Astrophysics - Abstract
There are four puzzles on 1E 1207.4-5209: (1) the characteristic age of the pulsar is much higher than the estimated age of the supernova remnant; (2) the magnetic field inferred from spin-down is significantly different from the value obtained from the cyclotron absorption lines; (3) the spinning down of the pulsar is non-monotonic; (4) the magnitude of the frequency's first derivative varies significantly and its sign is also variable. The third puzzle can be explained by a wide binary system, with orbital period from 0.2 to 6 yr. This letter proposes that all four puzzles can be explained naturally by an ultra-compact binary with orbital period of between 0.5 and 3.3 min. With the shortest orbital period and a close distance of 2 kpc, the characteristic amplitude of gravitational waves is $h\sim3\times10^{-21}$. It would be an excellent source of gravitational-wave detectors such as the Laser Interferometer Space Antenna., Comment: 8 pages, 3 figures, 1 Table

43. Systematic variation of the residual of PSR B1937+21, the trace of its companion star?

Astrophysics - Abstract
PSR B1937+21 was the first millisecond pulsar ever measured. Which has been appeared as a singular pulsar. The high-precision observation of this pulsar shows systemic long-term variation in the residual of time of arrivals. This paper modelled the secular variation by the orbital precession induced time delay of a binary pulsar system. The fitting requires that as a binary pulsar, PSR B1937+21 should have small companion star, $m_2\sim 10^{-2}M_{\odot}$, and projected semi-major axis, $x\sim 10^{-4}$s to $10^{-3}$s. Which corresponds to ignorable radial velocity of the pulsar to the line of sight. This might explain why it has been measured as a singular pulsar instead of a binary pulsar., Comment: 15 pages, 6 tables, 3 figures

Astrophysics - Abstract
The measurability of the spin--orbit (S--L) coupling induced orbital effect is dependent on the orientation and magnitude of the orbital precession velocity, ${\bf \Omega}_0$. This paper derives ${\bf \Omega}_0$ in the case that both spins in the binary system contribute to the spin--orbit (S--L) coupling, which is suitable for the most popular binary pulsars, Neutron star--White Dwarf star (NS--WD) binaries (as well as for NS--NS binaries). This paper shows that from two constraints, the conservation of the total angular momentum and the triangle formed by the orbital angular momentum, ${\bf L}$, the sum the spin angular momenta of the two stars, ${\bf S}$, and the total angular momentum, ${\bf J}$, the orbital precession velocity, ${\bf \Omega}_0$, along ${\bf J}$ is inevitable. Moreover, by the relation, $S/L\ll 1$, which is satisfied for a general binary pulsar, a significant ${\bf \Omega}_0$ (in magnitude) is inevitable, 1.5 Post Newtonian order (PN). Which are similar to the case of one spin as discussed by many authors. However unlike the one spin case, the magnitude of the precession velocity of ${\bf \Omega}_0$ varies significantly due to the variation of the sum the spin angular momenta of the two stars, ${\bf S}$, which can lead to significant secular variabilities in binary pulsars., Comment: 6 pages, 1 figure

45. Variation of dispersion measure: evidence of geodetic precession of binary pulsars

Astrophysics - Abstract
Variations of dispersion measure (DM) have been observed in some binary pulsars, which can not be well explained by the propagation effects, such as turbulence of the interstellar media (ISM) between the Earth and the pulsar. This paper provides an alternative interpretation of the phenomena, the geodetic precession of the orbit plane of a binary pulsar system. The dynamic model can naturally avoid the difficulties of propagation explanations. Moreover the additional time delay represented by the DM variation of two binary pulsars can be fitted numerically, through which some interesting parameters of the binary pulsar system, i.e., the moment of inertia of pulsars can be obtained, $I_1=(2.0\pm0.6)\times 10^{45}$g cm$^{2}$. The elimination of the additional time delay by the dynamic effect means that ISM between the these pulsars and the Earth might also be stable, like some other binary pulsars., Comment: 3 figures, 1 table

46. Secular variability, geodetic precession and moment of inertia of binary pulsars

Astrophysics - Abstract
More and more binary pulsars show significant secular variations, in which the measured projected semi-major axis, $\dot{x}^{obs}$, and the first derivative of orbital period, $\dot{P}_{b}^{obs}$, are several order of magnitude larger than the prediction of general relativity (GR). This paper shows that the geodetic precession induced orbital effects can explain both $\dot{x}$ and $\dot{P}_{b}$ measured in binary pulsars. Moreover, by this model we can automatically estimate the magnitude of the spin angular momenta of the pulsar and its companion star, and therefore the moment of inertia ($10^{44}$g cm$^2$ to $10^{45}$g cm$^2$) of pulsar of binary pulsar systems, which agrees well with theoretical predictions. In other words, the contamination (residual represented by $\dot{x}$ and $\dot{P}_{b}$) in pulsar timing measurements might be caused by geodetic precession, an interesting gravitational effect we have been seeking for.

50. Inclusion formation in Huntington's disease models

616.8 - Abstract
Huntington's disease (HD) is a progressive genetic neurodegenerative disease caused by the expansion of the CAG repeat in the HD gene and by the expression of pathological polyglutamine tracts in the huntingtin protein. Abnormal aggregates of protein (known as neuronal intranuclear inclusions) are found in the brains of HD patients and mouse models of HD. However, the role of inclusions in HD is controversial. To understand better the role of inclusions in HD, aggregate formation was studied using two well-established transgenic models of HD: an in vitro PCI 2 cell model carrying inducible transgenes with normal or pathological length CAG repeats and a transgenic mouse model, the R6/2 line. For the first time, time-lapse microscopy of inducible transgenic HD cells made it possible to visualise a disease-associated process in living cells. The experiments described in Chapter 3 showed that HD aggregate formation was dynamic, complicated and inversely related to cell death. Further investigations with these cells in Chapters 4-7 showed that some mechanisms underlying HD aggregate formation include proteasome dysfunction, calcineurin inhibition and cell differentiation. HD aggregate formation was also studied in R6/2 mouse brain. The experiments described in Chapter 8 showed that in vivo aggregate formation was dynamic and strikingly similar to that seen in vitro. Huntingtin aggregation was an early and ordered event that could occur as early as two weeks after birth, considerably earlier than that reported previously and well before any observable R6/2 phenotype. Huntingtin aggregation preceded ubiquitin labelling in vitro and in vivo, suggesting that the timing of ubiquitin labelling may be a determinant in the onset of HD pathology. Together, the work presented here suggests that aggregating huntingtin may not be immediately recognised by HD cells as 'toxic'. Thus, these studies support the idea that aggregate formation may have bimodal effects in HD, by being protective and toxic at different stages of aggregate development.
