Spontaneous electromagnetic fluctuations in unmagnetized plasmas. V. Relativistic form factors of weakly damped/amplified thermal modes

Closed analytical expressions for the spontaneously emitted fluctuation spectra of weakly damped/amplified fluctuations in unmagnetized plasmas are derived using fully relativistic dispersion functions and form factors for the important class of isotropic thermal plasmas. Especially, an electron-proton plasma is investigated in the limits of nonrelativistic and ultrarelativistic plasma temperatures. The results confirm the earlier nonrelativistic approach for positive values of the imaginary frequency γ and complete the nonrelativistic treatment for negative values of γ<0. The well known electrostatic, collective Langmuir mode also occurs within the relativistic theory of spontaneously emitted fluctuations and is analytically and graphically identified. For the first time, the ultrarelativistic temperature limit is analyzed for subluminal phase speeds, which leads to the identification of an additional, so far unknown, longitudinal subluminal collective mode.
Association between B-lines on lung ultrasound, invasive haemodynamics, and prognosis in acute heart failure patients

Abstract Aims Increased left atrial pressure leads to pulmonary congestion. Although the B-lines in lung ultrasound (LUS) are useful in detecting pulmonary congestion, data regarding the association between B-lines and invasive haemodynamics are inconsistent. This study aimed to explore the correlation of the B-line count by LUS with pulmonary capillary wedge pressure (PCWP) stratified for preserved and reduced ejection fraction (EF) in acute heart failure patients. Methods and results We performed a prospective observational study on 116 hospitalized patients with acute heart failure (mean age, 75.2 ± 10.3 years), who underwent right heart catheterization before discharge. LUS was performed in eight zones within 4 h of right heart catheterization and compared with PCWP separately in each EF group. Cardiac events were recorded 1 year after discharge. PCWP revealed a clear pivot point at which the B-lines began to increase in the overall cohort and each EF. Specific thresholds of the increase in B-lines were identified at 19 and 25 mmHg for preserved and reduced EF, respectively. Residual congestion at discharge was defined as the presence of ≥6 B-lines. Patients with residual congestion had a higher risk for cardiac events than those without residual congestion (hazard ratio, 12.6; 95% confidence interval, 4.71–33.7; log-rank, P < 0.0001). Conclusion A clear pivot point was associated with increased B-lines count in PCWP at 19 and 25 mmHg for preserved and reduced EF, respectively. Moreover, the increased B-line count above the defined cut-off used to quantify residual congestion was associated with significantly worse outcomes.
Astrocyte L-Lactate Signaling in the ACC Regulates Visceral Pain Aversive Memory in Rats

Pain involves both sensory and affective elements. An aspect of the affective dimension of pain is its sustained unpleasantness, characterized by emotional feelings. Pain results from interactions between memory, attentional, and affective brain circuitry, and it has attracted enormous interest in pain research. However, the brain targets and signaling mechanism involved in pain remain elusive. Using a conditioned place avoidance (CPA) paradigm, we show that colorectal distention (CRD magnitude ≤ 35 mmHg, a subthreshold for pain) paired with a distinct environment can cause significant aversion to a location associated with pain-related insults in rats. We show a substantial increase in the L-lactate concentration in the anterior cingulate cortex (ACC) following CPA training. Local exogenous infusion of lactate into the ACC enhances aversive memory and induces the expression of the memory-related plasticity genes pCREB, CREB, and Erk1/2. The pharmacological experiments revealed that the glycogen phosphorylation inhibitor 1,4-dideoxy-1,4-imino-D-arabinitol (DAB) impairs memory consolidation. Furthermore, short-term Gi pathway activation of ACC astrocytes before CPA training significantly decreases the lactate level and suppresses pain-related aversive learning. The effects were reversed by the local infusion of lactate into the ACC. Our study demonstrates that lactate is released from astrocytes in vivo following visceral pain-related aversive learning and memory retrieval and induces the expression of the plasticity-related immediate early genes CREB, pCREB, and Erk1/2 in the ACC. Chronic visceral pain is an important factor in the pathophysiology of irritable bowel syndrome (IBS). The current study provides evidence that astrocytic activity in the ACC is required for visceral pain-related aversive learning and memory.
Assessing the efficacy of extruded seed pellets and microbial amendments for native revegetation

Worldwide, there is a strong need for new, innovative, large‐scale approaches to restoring diverse native vegetation. Seed‐based revegetation, while often employed, can suffer from low plant establishment. Various seed coating technologies have been widely employed for decades to promote efficient agricultural planting; however, a significant obstacle to the implementation of this technology for native species revegetation is the limited access to the expertise and techniques which are mostly confidential to and specialized for the agrochemical industry. Here we investigated whether the seeds of Australian native species may benefit from extruded pelleting, measuring both seedling emergence and early growth, and testing the pellets with and without the addition of a commercial plant probiotic. A manipulative glasshouse experiment was carried out with three treatments (bare seeded; standard pellets; pellets amended with a probiotic) for four native plant species. Incorporation of seeds within standard pellets was shown to maintain high percentages of emergence and improve growth of three of the tested species (Daviesia ulicifolia, Hardenbergia violacea, and Indigofera australis) in the glasshouse setting, with increases in mean biomass of 83, 385, and 1,002%, respectively. However, emergence in the fourth species (Bursaria spinosa) was low in all seed treatments, perhaps due to excessive sowing depth (bare seeds), while combined with being encased inside a pellet. Relative to the standard pellets, probiotic amended pellets did not impart further detectable emergence or growth benefits. Ultimately, these results highlight exciting prospects for the application of extruded seed pellets in facilitating efficient use of seed in the revegetation of some native species.
Cloud Collision-induced Star Formation in Sagittarius B2. I. Large-Scale Kinematics

We present maps of a ~ 14 pc × 20 pc region covering the Sgr B2 molecular cloud complex in the 13CO (1-0) and CS (1-0) lines with high angular resolution. A more restricted central area was also mapped in the C18O (1-0) line. The 13CO cloud consists of two components: a compact core of ~ 3 pc in diameter roughly centered on Sgr B2(M) and an extended plateau of ~ 17 pc × 7.5 pc area containing the maser sources and most of the H II regions. Compact, massive (~ 3 × 105 M☉) C18O cores are associated with Sgr B2(M) and Sgr B2(N). The obtained intensity distributions are compared with those of molecular masers and compact H II regions reported in the literature. Low-velocity (40-65 km s-1) masers, with positions roughly aligned in the north-south line connecting the three major compact H II region complexes, are located near the eastern margin of a large hole in the low-velocity molecular cloud. In contrast, most of the high-velocity (65-80 km s-1) masers are distributed near the center of a compact molecular cloud at higher velocity, where a shock seems to have occurred. These results provide further evidence supporting the cloud-cloud collision hypothesis based on limited 13CO (1-0) data. In addition, this hypothesis appears to be consistent with a wide range of new observations that have appeared in the literature.
Open-Label Placebo Effects on Psychological and Physical Well-Being: A Conceptual Replication Study

Background Contrary to traditional placebos, open-label placebos (OLP) abstain from deception, i.e., participants are openly informed to receive an inert substance. Studies in clinical and healthy samples evidence the efficacy of OLPs. This study aims to conceptually replicate and expand findings of a recent OLP study in healthy participants while implementing a within-subject design and daily instead of retrospective assessments. Additionally, the effect of a brand name on the medicine container is tested and possible predictors of the OLP effects are explored. Method Healthy participants (N = 75) received OLP and no placebo for 5 days each (randomized sequence) and answered daily questionnaires on sleep quality, bodily symptoms, mental well-being, and psychological distress. The medicine container of half the participants had a brand name, the remaining did not. Different personality traits and situational factors were assessed. Results Mental and physical well-being did not differ between OLP and control phase, i.e., overall, no OLP effect emerged. Contrast analysis indicated that an OLP effect emerged for sleep quality and psychological distress when no brand name was present. Further, an OLP effect emerged in persons with higher expectations for bodily symptoms (r = .23, p = .046) and psychological distress (r = .24, p = .037). Conclusions Methodological differences to the original study are discussed as an explanation for the failure to induce overall OLP effects. Future studies should continue to replicate previous findings and determine the exact conditions of successful implementation of OLP effects in healthy as well as clinical samples.

Additionally, the majority of the studied nurses (88.6%) had unsatisfactory practice level compared with vast majority (92%) of them had satisfactory level of practice post educational program and there were high statistical improvement on critically ill patients’ clinical outcomes during intra-hospital transportation. Conclusion: A well designed safe intra-hospital transportation education program could positively affect the nurses' knowledge and practice and decline the patients' adverse events and complication during transportation Recommendation : It was recommended that encouraging nurses' in-service training program can improve critically ill patients' safety during intra-hospital transportation.
Observation of the anomalous current–voltage characteristics of GaAs/n+‐InGaAs/GaAs doped‐channel structure

A GaAs/n+‐In0.2Ga0. 8As/GaAs doped‐channel field‐effect transistor structure has been fabricated and studied. A typical transistor performance with a threshold voltage of about −3.0 V and transconductance of up to 160 mS/mm is obtained in the lower gate‐source voltage (VGS <−1.0 V) regime. However, for some devices, the three‐terminal‐controlled N‐shaped negative‐differential‐resistance (NDR) behavior is observed at the saturation regime of current–voltage characteristics under higher gate‐source bias (VGS≥−1.0 V) condition. The interesting NDR phenomenon is believed to be attributed to the real‐space transfer and deep‐level electron trapping effect.
Different Dosage Regimens of Tanezumab for the Treatment of Chronic Low Back Pain: A Meta-analysis of Randomized Controlled Trials

Objective The aim of this study was to assess the efficacy of different dosage regimens of tanezumab among individuals living with chronic low back pain (CLBP). Methods PubMed, Embase, The Cochrane Library, and other databases were searched from inception until August 2021. Randomized controlled trials investigating the efficacy and safety of tanezumab in individuals with CLBP were included. Data were extracted independently by 2 investigators and assessed the study quality by the Cochrane risk-of-bias tool. The measurements include low back pain intensity and Roland-Morris Disability Questionnaire. The incidence of adverse events and serious adverse events was set to assess the safety of tanezumab for CLBP. Results and Discussion Three high-quality randomized controlled trials with 3414 patients were finally included in our analysis. Tanezumab, respectively, led to a notable decrease compared with placebo in low back pain intensity (mean difference, −0.62; 95% confidence interval [CI], −0.77 to −0.46; P < 0.01) and Roland-Morris Disability Questionnaire (mean difference, −0.64; 95% CI, −0.80 to −0.47; P = 0.01). In addition, no significant difference existed between tanezumab and placebo groups (risk ratio, 1.10; 95% CI, 0.81–1.49; P = 0.55) in the adverse events and (risk ratio, 1.06; 95% CI, 0.34–3.27; P = 0.93) serious adverse events. Conclusions Intravenous and subcutaneous tanezumab injections as treatment for improving CLBP have promising clinical application as its great improvement on all efficacy and its controllable safety issues. Furthermore, intravenous and subcutaneous tanezumab injections were proved to achieve excellent and long-term curative effect on CLBP through our subgroup analysis and comparison.

Analytical solutions of in-plane static problems for non-uniform curved beams including axial and shear deformations

Exact analytical solutions for in-plane static problems of planar curved beams with variable curvatures and variable cross-sections are derived by using the initial value method. The governing equations include the axial extension and shear deformation effects. The fundamental matrix required by the initial value method is obtained analytically. Then, the displacements, slopes and stress resultants are found analytically along the beam axis by using the fundamental matrix. The results are given in analytical forms. In order to show the advantages of the method, some examples are solved and the results are compared with the existing results in the literature. One of the advantages of the proposed method is that the high degree of statically indeterminacy adds no extra difficulty to the solution. For some examples, the deformed shape along the beam axis is determined and plotted and also the slope and stress resultants are given in tables.
Perception of noise-vocoded speech sounds: Sentences, words, accents and melodies

Recent works on perception of noise-vocoded speech sound (NVSS) have revealed that amplitude envelope information is very important for speech perception when spectral information is not sufficiently available. Basically, the fundamental frequency information is not available and formant peaks cannot not be identified in NVSS. However, we can even recognize accent and distinguish male voice from female voice in NVSS. More, melody can be created from lyrics once lyrics are intelligible. In the present study, findings from fMRI measurement are introduced to show neural activities in the central nervous system during listening to NVSS. The present data indicate that various sites in the brain, which are not ordinarily used for speech recognition, participate in making NVSS intelligible. Applications of the present work include an innovative speech processor and a training system for hearing impaired people.
Quantum field theory and composite fermions in the fractional quantum Hall effect

We derive a composite fermion model for the fractional quantum Hall effect from relativistic quantum electrodynamics. With simple arguments it is shown that a special Chern Simons transformation of the Dirac electrons in four spacetime dimensions leads in the low energy limit to a single particle Hamiltonian for composite fermions in three dimensions with correction terms such as Rashba‐ or Dresselhaus‐spin‐orbit coupling and zitterbewegung. Furthermore we provide a mechanism to quantum‐mechanically project the quantum fields defined in the four dimensional Minkowski space to three dimensions. This leads to a relativistic field theory and especially a composite fermion field theory in three dimension. This projection map can be combined with the projection onto a Landau level or composite fermion Landau level respectively. This results in a quasi relativistic quantum field theory on a noncommutative plane. The phenomenological models resulting from this approach are discussed and allow a systematical exploration of the effects of the spin and the condensation in a Landau level. We expect from the relativistic approach corrections in terms of spin‐orbit coupling effects. From the projection onto Landau levels we expect a modification of the dispersion relation and a modified composite fermion mass. Furthermore, the BRST quantization for Chern Simons theories with compact gauge group is reviewed and the phenomenological consequences within a composite fermion model with spin are discussed. The connection to Wess Zumino Witten theories is recalled and a possible link between the corresponding central charge of the related affine Lie algebra and the composite fermion filling factor is pointed out.
