New Infrared Veiling Measurements and Constraints on Accretion Disk Models for Classical T Tauri Stars

We analyze K-band infrared (IR) spectra of 14 classical and nine naked T Tauri stars. Using five lines of CO, we determine v sin i and show that IR and optical measurements agree well. From this we conclude that K-band absorption lines generally form in the stellar photosphere. Using line equivalent widths, we measure K-band veiling for classical T Tauri stars in our sample. Accretion disk models constrained by existing stellar and accretion parameters yield testable predictions for K-band veiling. In the context of these models, we examine sources of IR emission from the disk. The importance of disk reprocessing of emission from the accretion shock as material strikes the stellar surface is shown. We then show that current models constrained by the most recent estimates of mass accretion have a difficult time reproducing many of our high-veiling results. We suggest that dust out of the plane of the accretion disk (possibly in the magnetospheric flow itself) may account for much of the emission missing in the models.
The highly polarized hidden quasar IRAS 09104+4109 : a double-lobed radio source in a rich cluster

IRAS 09104+4109 is the second most luminous active galactic nucleus (AGN) so far discovered by IRAS, with L bol ∼10 12.6 h -2 L ○. Kleinmann et al. have shown it to have a strong Seyfert 2 emission-line spectrum (z=0.442), with a range of excitations and very large equivalent widths but no broad lines. They suggested that this V∼19 cD galaxy hides a luminous QSO that ionizes the narrow-line region and heats dust within ∼130 pc of the central engine. Here we further investigate the geometry and environment of this extreme AGN by means of broad-band polarimetry, spectropolarimetry, new spectroscopy, and radio imaging
A Scenario for the Critical Fluctuations near the Transition of Few-Bilayer Films of High-Temperature Cuprate Superconductors

We study the critical fluctuations near the resistive transition of very thin films of high-temperature cuprate superconductors composed of a number N of only a few unit cells of superconducting bilayers. For that, we solve the fluctuation spectrum of a Gaussian–Ginzburg–Landau model for few-bilayers superconductors considering two alternating Josephson interlayer interaction strengths, and we obtain the corresponding paraconductivity above the transition. Then, we extend these calculations to temperatures below the transition through expressions for the Ginzburg number and Kosterlitz–Thouless-like critical region. When compared with previously available data in YBa2Cu3O7−δ few-bilayers systems, with N = 1 to 4, our results seem to provide a plausible scenario for their critical regime.
Applying cognitive approach to teaching prepositions in business English: A case study

The paper sets out to investigate the potential advantages of applying insights from the field of cognitive linguistics to teaching prepositions in business English over an approach relying on the traditional linguistic framework. For the study, three of the English prepositions were chosen: to, for, and at. Study participants were divided into two groups: an experimental group, which received a cognitive treatment of the three prepositions; and a control group, which received an instruction relying on traditional accounts. The participants were administered three tests in total: a pretest, an immediate posttest, and a delayed posttest. Their scores were taken on all three tests and then compared within each group and between the groups. To calculate the results, descriptive statistics, t-test of independent means and one-way ANCOVA were used. Grounding the expected results in expert literature, it was anticipated to obtain the results indicative of the advantage of the cognitive approach. According to the study results, the experimental group outperformed the control group at all levels of statistical analysis. The results suggest that a strategic incorporation of a cognitive view of the structure of language into the foreign language classroom could facilitate better understanding, more effective learning and long-term retention of the language points taught.
A ratio limit theorem for contraction projections and applications

The similarities between martingale convergence theory and pointwise ergodic theory are now well known [5, 7, 9, 10]. In [5] the similarity between the proofs of the Hopf– Dunford–Schwartz individual ergodic theorem and the martingale convergence theorem is systematically exploited to produce very general ” maximal ergodic ” inequalities for certain sequences of contractions on L1-spaces. A different approach by Rota [10] and Rao [9] leads to a unified convergence theory for martingales and Abel limits. Bishop [1] has produced ” upcrossing” inequalities which yield both theChacon-Ornstein theorem [4] and the martingale convergence theorem.
Physiotherapists’ Perceptions and Willingness to Use Telerehabilitation in Greece: A Cross-Sectional Study

Introduction Coronavirus disease 2019 (COVID-19) has affected the healthcare system and the practice of physiotherapists. Telerehabilitation is an alternative method of delivering physiotherapy services. The aim of this study was to investigate physiotherapists’ knowledge, beliefs, and willingness to use telerehabilitation in Greece during the COVID-19 pandemic. Materials and methods In this cross-sectional study, Greek physiotherapists completed an online survey between January and February 2022. A questionnaire was distributed via the Panhellenic Physiotherapy Association (PSF). The questionnaire involved 26 items on demographic background, use of technology, overall perceptions, the experience of telerehabilitation, and their opinion on the future of telerehabilitation. The study protocol was approved by the Ethical Committee of the University of Patras, Greece. Results Participants in this study were 213 physiotherapists (female 57.7%; mean age 39.84±8 years). Most physiotherapists (n=118; 55.4%) were working in a private clinic in the areas of outpatient orthopedics, geriatrics, and neurorehabilitation. Overall, most participants (55%) reported increased use of telerehabilitation strategies during the COVID-19 pandemic. A total of 130 physiotherapists (n=61.3%) believed that telerehabilitation may be beneficial as a supplementary way of patient management. Greek physiotherapists made use of low-cost and easily accessible digital technologies, such as mobile phones and online meeting tools (e.g., Skype, Zoom). Although most physiotherapists (79.8%) reported that they wanted to receive more information about digital technology and telerehabilitation, only 42.1% of them did intend to work remotely after the pandemic. Conclusion Most of the participants were willing to deliver physiotherapy via telerehabilitation. Specific education and training programs need to be provided to physiotherapists during and after the pandemic. Healthcare managers should consider the use of telerehabilitation and design guidelines and policies to manage telerehabilitation practices in Greece.
Tardive Dyskinesia Following Low-Dose Risperidone

Tardive dyskinesia is an involuntary athetoid or choreiform movement lasting a minimum of a few weeks. It is associated with the use of neuroleptic medication for at least three months and persists beyond four to eight weeks. Tardive dyskinesia usually occurs as a result of the long-term use of dopamine receptor-blocking agents, mainly first-generation antipsychotics or a high-dose, second-generation antipsychotic. We present a case of a 28-year-old female with osteogenesis imperfecta presented later with major depressive disorder with psychotic features. She was given a low-dose second-generation antipsychotic, namely, risperidone (2 mg) for psychosis for a cumulative duration of three months. As a result, she developed extrapyramidal symptoms in the form of akathisia, axial dystonia, involuntary movement of the right hand, and smacking movement of the lips. Symptoms persisted for more than eight weeks despite discontinuing risperidone and switching to quetiapine. After the exclusion of other differential diagnoses, she was labeled as a case of tardive dyskinesia. More studies are needed to assess whether undiscovered contributing factors to tardive dyskinesia exist and to understand how second-generation antipsychotics (SGAs) contribute to the development of tardive dyskinesia.
Timescales of Dike Growth and Chamber Deflation Constrain Magma Storage and Transport Pathways During Kīlauea's 2018 Lower East Rift Zone Intrusion

The intrusion of magma into Kīlauea's lower East Rift Zone in May 2018 led to the largest eruption along this segment of the volcano in over 200 years. As magma drained from the rift zone, leading to the collapse of Pu'u ‘Ō‘ō, pressure at the summit initially remained elevated and dropped at a slower rate compared to historical intrusion events. The anomalously long timescale of summit deflation suggests that the dike was fed from multiple sources. Here we show that dikes can serve as “dipsticks” of magma reservoirs and that the co‐evolution of dike growth and reservoir deflation constrains key magma transport parameters. Using coupled dike‐chamber models constrained by ground deformation and seismicity, we test four configurations of magma plumbing in order to illuminate which reservoirs and transport pathways were activated during the intrusion phase (30 April to 3 May) of the 2018 event. Slow summit deflation relative to the rate of dike propagation is best explained by a model in which the dike initiates from a compressible magma reservoir in the East Rift Zone, which then drains magma upstream from the Halema'uma'u reservoir through a shallow transport system. We use a Bayesian Markov chain Monte Carlo (MCMC) approach to estimate storage parameters for both reservoirs as well as the effective conductivity of the shallow magma transport system in the East Rift Zone, finding good agreement with independent estimates. Our results suggest that the rupture of reservoirs from within the East Rift Zone presents a unique hazard at Kīlauea.
Investigation of academic motivation in medical students and its association with clinical education quality, academic achievement, and academic burnout

BACKGROUND: Improving the quality of clinical education requires continuous review of the current situation, identifying strengths, and correcting weaknesses. This study aimed to investigate the association between academic motivation with quality of clinical education, academic achievement, and burnout. MATERIALS AND METHODS: This cross-sectional study was done in 2020 on all of the 140 internship students of Shahrekord University of Medical Sciences, using the consensus method. The data collection tools included standard questionnaires such as Herman's Academic Motivation, Clinical Education Quality, Maslach Modified Academic Burnout, Pham and Taylor Academic Achievement, Satisfaction of Educational Welfare Facilities. Data were analyzed using SPSS (ver. 22) software and descriptive statistics (mean, standard deviation, frequency and percentage of frequency), Spearman rank, correlation coefficient and Mann–Whitney and Kruskal–Wallis statistical tests. P < 0.05 is considered statistically significant. FINDINGS: The mean ± SD of age was 25.68±2.03. 86 (61.4%) of the internship were female and 87 (62.1%) were single. Mean± SD of academic motivation and quality of clinical education were 81.51± 8.73 and 28/99± 11/52 respectively. Also, the Mean± SD of academic achievement and academic burnouts were 147/61± 14/94 and 42/37± 10/42 respectively. RESULTS: Academic motivation had a meaningful and positive relationship with academic achievement and satisfaction of welfare facilities but a negative correlation with academic burnout. Also, academic achievement and academic burnout had a negative correlation but a positive correlation was seen between the quality of clinical education and satisfaction of welfare facilities. CONCLUSION: Considered the results, recommended improving welfare education facilities by using up-to-date training aids, upgrading educational infrastructure, and employ young staff in the education office. For improving the quality of clinical education, appropriate educational methods, conducting developmental assessments continuously, using simulated environments, and improving students' motivation.
A meta-analysis and of clinical values of 11 blood biomarkers, such as AFP, DCP, and GP73 for diagnosis of hepatocellular carcinoma

Abstract Background Hepatocellular carcinoma lacks ideal diagnostic biomarkers. There is a lack of scientific evaluation of relevant promising biomarkers as well. Therefore this study reanalyzes the related studies of 11 blood biomarkers of HCC, and compares the diagnostic value of these biomarkers for HCC systematically. Methods The relevant literatures on the diagnostic value in HCC of 11 blood indexes in recent 5 years were searched in PubMed, Embase, and Cochrane libraries. Data were extracted and analyzed. Results Finally, 83 literature studies were brought into meta-analysis. The pooled sensitivity and specificity of AFP were 0.61 and 0.87, respectively. The AUC of AFP were 0.78. The AUC and sum of sensitivity and specificity of the combination of AFP and other biomarkers were all significantly higher than that of AFP, including AFP + AFP-L3 + DCP, AFP + DCP, AFP/DCP, AFP + GPC3. Among other biomarkers, the AUC and sum of sensitivity and specificity of biomarkers including DCP, GPC3, GP73, Hsp90alpha, midkine, and OPN were significantly higher than that of AFP. In this study, GP73 had the highest sum of sensitivity and specificity (1.78) and AUC (0.95). Conclusions The pooled sensitivity and specificity of AFP were 0.61 and 0.87, respectively. The AUC of AFP were 0.78. The combination of AFP and other biomarkers improved the diagnostic efficiency. The diagnostic value of biomarkers including DCP, GPC3, GP73, Hsp90alpha, midkine, and OPN was higher than that of AFP. GP73 had the best diagnostic value for HCC with the highest sum of sensitivity and specificity (1.78) and AUC (0.95). KEY MESSAGES The pooled sensitivity and specificity of AFP were 0.61 and 0.87, respectively. The AUC of AFP were 0.78. The combination of AFP and other biomarkers improved the diagnostic efficiency of HCC. The diagnostic value of biomarkers including DCP, GPC3, GP73, Hsp90alpha, midkine, and OPN was higher than that of AFP. GP73 had the best diagnostic value for HCC.
Guillain–Barre/Miller–Fisher overlap syndrome or acute, motor and sensory, axonal neuropathy with cranial nerve involvement?

Letter to the Editor With interest, we read the article by Liang et al. about a 64 y-old male with Guillain–Barre syndrome (GBS) Miller–Fisher syndrome (MFS) overlap syndrome starting 11 d after the second jab of the Sinovac-CoronaVac vaccine. Intravenous immunoglobulins (IVIG) and acupuncture resulted in complete recovery at the last followup, 54 d after dismissal. The study is attractive but raises concerns that require further discussion. We disagree with the diagnosis GBS-MFS overlap syndrome. According to the nerve conduction studies (NCSs) the patient had axonal, sensorimotor neuropathy. Because there was obvious dissociation cyto-albuminique, the patient should be classified as acute, motor and sensory, axonal neuropathy (AMSAN) with cranial nerve involvement rather than GBS-MFS overlap. Cranial nerves affected in the index patient were the 6 and 7th cranial nerve. AMSAN is more prevalent in the Eastern compared to the Western hemisphere, where acute, inflammatory demyelinating polyneuropathy (AIDP) prevails. Arguments against MFS are that the patient had facial palsy and that ophthalmoparesis was incomplete. Only bulb abduction was impaired, whereas in MFS there is usually ophthalmoparesis for all degrees of eye movements. Missing are the cytokine and chemokine levels and the titers of the glial acidic fibrillary protein (GAFP) in the CSF. These parameters have been found elevated in GBS or central nervous system disease following a SARS-CoV-2 vaccination. We disagree with the notion that the index is the first presenting with MFS-GBS overlap syndrome. Though rare, GBS-MFS has been previously reported in single patients. Missing is the information whether the autonomic innervation of the heart was impaired or not. AMSAN commonly is associated with autonomic dysfunction, which is why we should know if blood pressure regulation was impaired or not and whether supra-ventricular or ventricular arrhythmias were detected on long-term electrocardiogram (ECG) recordings or telemetry. Particularly, we should know if the Valsalva maneuver was positive or negative, if there was postural tachycardia syndrome (POTS), increased or decreased heart rate variability on frequency analysis of long-term (ECG) recordings, and an abnormal tilt test. We should also know if there were clinical or echocardiographic signs of heart failure and if troponin or pro-brain natriuretic peptide (pro-BNP) were elevated or not. The term “right facial diplegia” is misleading. Do the authors mean facial diplegia with right-sided predominance or do they truly mean right-sided facial palsy without affection of the contralateral side? Overall, the study carries obvious limitations that require reevaluation and discussion. Clarifying these weaknesses would strengthen the conclusions and could improve the study. MFS is questionable if the facial nerves are affected in addition to cranial nerves innervating extra-ocular eye muscles.
Forward‐reverse shock pairs associated with transient disturbances in the solar wind at 1 AU

While relatively common in the outer heliosphere, forward-reverse shock pairs occur rarely in the solar wind at 1 AU. Using the combined solar wind plasma and magnetic field data from ISEE 3 for the interval from August 1978 through February 1980 we have identified several examples of such shock pairs at 1 AU. Two of these shock pair events were clearly associated with transient disturbances rather than with corotating streams. Strong bidirectional electron heat flux events, which we identify as the coronal mass ejecta (CME) driving the shocks, were detected during both of these disturbances. In the stronger of the two disturbances the reverse shock was found within the CME and was separated from the forward shock by ∼0.2 AU; the pressure was nearly constant between the two shocks. On the other hand, in the weaker of the two disturbances the reverse shock had propagated entirely through the CME and trailed the forward shock by ∼0.3–0.4 AU; the pressure declined substantially and monotonically between the two shocks. The overall disturbance profiles for these two events compare favorably with the results of previously published numerical simulations. On the basis of those simulations we suggest that these two events are prototypes of “driven” and “blast” disturbances, wherein the time scale of the initial velocity perturbation near the Sun is, or is not, short compared to the transit time to 1 AU. Our observations support the notion that reverse shocks in transient disturbances are most likely to be found near the central axes of such disturbances.
Carbon Nanotubes as Carriers in Drug Delivery for Non-Small Cell Lung Cancer, Mechanistic Analysis of Their Carcinogenic Potential, Safety Profiling and Identification of Biomarkers

Abstract Non-small cell lung cancer (NSCLC) is a global burden leading to millions of deaths worldwide every year. Nanomedicine refers to the use of materials at the nanoscale for drug delivery and subsequent therapeutic approaches in cancer. Carbon nanotubes (CNTs) are widely used as nanocarriers for therapeutic molecules such as plasmids, siRNAs, antisense agents, aptamers and molecules related to the immunotherapy for several cancers. They are usually functionalized and loaded with standard drug molecules to improve their therapeutic efficiency. Functionalization and drug loading possibly decrease the genotoxic and carcinogenic potential of CNTs. In addition, the targeted cytotoxic properties of the drug improve and undesired toxicity decreases after drug loading and/or conjugation with proteins, including antibodies. For intended drug delivery, a lysosomal pH of 5.5 is more suitable and effective for the slow and extended release of cytotoxic drugs than a physiological of pH 7.4. Remarkably, CNTs possess intrinsic antitumor properties and are usually internalized by endocytosis. After being internalized, several mechanisms are involved in the therapeutic and carcinogenic effects of CNTs. They are generally safe for therapy, and their toxicity profile remains dependent on their physicochemical properties. Moreover, the dose, route, duration of exposure, surface properties and degradative potential determine the toxicity outcomes of CNTs locally or systemically. In summary, the use of CNTs in drug delivery and NSCLC therapy, as well as their genotoxic and carcinogenic potential and the possible mechanisms, has been discussed in this review. The therapeutic index is generally high for NSCLC cells treated with drug-loaded CNTs; therefore, they are effective carriers in implementing targeted therapy for NSCLC.
Analysis of the Effect of Leadership Style and Motivation on the Performance of Health Workers at UPT PKM Dlanggu, Mojokerto Regency in 2021

An organization must have good performance to be able to exist and excel in the competition. Performance is an indicator of good or bad management decisions in decision making. Performance is influenced by leadership style and employee motivation. Good or high performance can help the organization make a profit, and vice versa if the performance decreases it can harm the organization. The purpose of the study was to analyze the influence of leadership style and motivation on the performance of the employees of the Technical Service Unit of the Dlanggu Public Health Center, Mojokerto Regency in 2021. This research was carried out for 1 month. The population in this study were all employees of the Technical Service Unit of the Dlanggu Public Health Center, Mojokerto Regency. The sample in this study was 67 people. The results obtained show that Based on the results of the Logistics Regression test, shows that for the leadership style variable on the performance variable p value = 0.003 which means that there is an influence of leadership style on the performance variable and on the motivation variable on performance, p value of = 0,035 which means that there is an influence of motivation on performance. The Omnibus law sig value of 0.000 is smaller than 0.05 which indicates that there is a significant influence of Leadership Style and Motivation simultaneously on the Performance variable. It can be concluded that there is an influence of leadership style and motivation on employee performance.
Transverse Vibrations of Double‐Tapered Cantilever Beams

The differential equation is developed from the Bernoulli‐Euler equation for the free vibrations of a double‐tapered cantilever beam. The beam tapers linearly in the horizontal and in the vertical planes simultaneously. From a computer solution of this equation, a table has been developed from which the fundamental frequency, second, third, fourth, and fifth harmonic can easily be obtained for various taper ratios. Charts are plotted for selected taper ratios in the vertical plane to show the effect of taper ratios on frequency.
Macroecological and biogeographical patterns of limb reduction in the world's skinks

Limb reduction is a dramatic evolutionary transition, yet whether it is achieved in similar trajectories across clades, and its environmental drivers, remain unclear. We investigate the macroevolutionary and biogeographical patterns of limb reduction in skinks, where limb reduction occurred more often than in any other tetrapod clade, and test their associations with substrate categories using a global database. We test for habitat associations of body shapes in a group of Australian skinks using quantitative habitat data.
