Identifying Errors made by EFL College Students in Dictation
Authors: Afrah M. Lahad  
Published: May 2024

A test is an important device for teachers and for learners; for teachers in
that it helps to assess the students' EL performance and for learners in that it
helps them to discover the areas of weakness and strength in their
performances.

Dictation is one of the integrative tests that have proved their proficiency in
measuring different language skills, like listening comprehension and spelling .
It is a reading passage (100 to 200 words) which is read by the teacher three
times at a normal speed . The students' task is to write down what the teacher
read in the second reading . However, experienced instructors in the field of
TEFL realise that learners have many errors in writing .

Hence, the present study aims at identifying, classification and explaining
the errors that EFL college students make during applying dictation tests .

The sample of the study is 55 students randomly chosen from the second-
year students at the Department of English, College of Basic Education ,
Al-Mustansiriyah University during the academic year 2005 / 2006.

The instrument of the study is a ready test which consists of a 162- word
passage. The passage is intended to test advanced students' dictation. The test is
submitted to a jury of specialists to ensure its validity.

The test results revealed that the sample subjects have many errors which
the researcher classified into comprehension, grammatical and spelling errors.
Spelling errors formed the largest percentage of the total number of errors
which are, in turn, classified into subcategories .

In the light of the obtained results some conclusions are drawn, number of
recommendations are made, and several suggestions for further research are
presented .

Abstract
The hot, X-ray-emitting phase of the circumgalactic medium of massive galaxies is believed to be the reservoir of baryons from which gas flows onto the central galaxy and into which feedback from active galactic nuclei and stars inject mass, momentum, energy, and metals. These effects shape the velocity fields of the hot gas, which can be observed via the Doppler shifting and broadening of emission lines by X-ray integral field units. In this work, we analyze the gas kinematics of the hot circumgalactic medium of Milky Way–mass disk galaxies from the TNG50 simulation with synthetic observations to determine how future instruments can probe this velocity structure. We find that the hot phase is often characterized by outflows from the disk driven by feedback processes, radial inflows near the galactic plane, and rotation, although in some systems the velocity field is more disorganized and turbulent. With a spectral resolution of ∼1 eV, fast and hot outflows (∼200–500 km s−1) can be measured, depending on the orientation of the galaxy on the sky. The rotation velocity of the hot phase (∼100–200 km s−1) can be measured using line shifts in edge-on galaxies, and is slower than that of colder gas phases but similar to stellar rotation velocities. By contrast, the slow inflows (∼50–100 km s−1) are difficult to measure in projection with these other components, but may be detected in multicomponent spectral fits. We find that the velocity measured is sensitive to which emission lines are used. Measuring these flows will constrain theories of how the gas in these galaxies evolves.
Probing Depth Variations of Solar Inertial Modes through Normal Mode Coupling
Authors: Mandal Krishnendu , Hanasoge Shravan M. 
Published: May 2024

Abstract
Recently discovered inertial waves, observed on the solar surface, likely extend to the deeper layers of the Sun. Utilizing helioseismic techniques, we explore these motions, allowing us to discern inertial mode eigenfunctions in both radial and latitudinal orientations. We analyze 8 yr of space-based observations (2010–2017) taken by the Helioseismic and Magnetic Imager on board the Solar Dynamic Observatory using normal mode coupling. Couplings between the same and different-degree acoustic modes and different frequency bins are measured in order to capture the various length scales of the inertial modes. We detect inertial modes at high latitude with azimuthal order t = 1 and frequency ∼ −80 nHz, measured in a corotating frame with a rotation frequency of 453.1 nHz. This mode is present in the entire convection zone. The presence of Rossby modes may be seen down to a depth of ∼0.83R
⊙, and the Rossby signal is indistinguishable from noise below that depth for high azimuthal order. We find that the amplitudes of these modes increase with depth down to around 0.92R
⊙ and decrease below that depth. We find that the latitudinal eigenfunctions of Rossby modes deviate from sectoral spherical harmonics if we use a similar approach as adopted in earlier studies. We find that spatial leakage and even pure noise in the measurements of nonsectoral components can also explain the abovementioned characteristics of the latitudinal eigenfunctions. This realization underscores the necessity for careful interpretation when considering the latitudinal eigenfunctions of Rossby modes. Exploring the depth-dependent characteristics of these modes will enable us to capture interior dynamics distinctly, separate from p-mode seismology.
The Effect of Starspots on Spectroscopic Age and Mass Estimates of Nonaccreting T Tauri Stars in the Taurus–Auriga Star-forming Region

Published: May 2024

Abstract
Accurate age and mass determinations for young pre-main-sequence stars are made challenging by the presence of large-scale starspots. We present results from a near-infrared spectroscopic survey of 10 T-Tauri Stars in Taurus-Auriga that characterize spot-filling factors and temperatures, the resulting effects on temperature and luminosity determinations, and the consequences for inferred stellar masses and ages. We constructed composite models of spotted stars by combining BTSettl-CIFIST synthetic spectra of atmospheres to represent the spots and the photosphere along with continuum emission from a warm inner disk. Using a Markov Chain Monte Carlo algorithm, we find the best-fit spot and photospheric temperatures, spot-filling factors, as well as disk-filling factors. This methodology allowed us to reproduce the 0.75–2.40 μm stellar spectra and molecular feature strengths for all of our targets, disentangling the complicated multicomponent emission. For a subset of stars with multiepoch observations spanning an entire stellar rotation, we correlate the spectral variability and changes in the filling factors with rotational periods observed in K2 and AAVSO photometry. Combining spot-corrected effective temperatures and Gaia distances, we calculate luminosities and use the Stellar Parameters of Tracks with Starspots models to infer spot-corrected masses and ages for our sample of stars. Our method of accounting for spots results in an average increase of 60% in mass and a doubling in age with respect to traditional methods using optical spectra that do not account for the effect of spots.

Abstract
On 2023 March 6, the Gaia telescope alerted a 2 mag burst from Gaia23bab, a young stellar object in the Galactic plane. We observed Gaia23bab with the Large Binocular Telescope obtaining optical and near-infrared spectra close in time to the peak of the burst, and collected all public multiband photometry to reconstruct the historical light curve. The latter shows three bursts in 10 years (2013, 2017, and 2023), whose duration and amplitude are typical of EXor variables. We estimate that, due to the bursts, the mass accumulated on the star is about twice greater than if the source had remained quiescent for the same period of time. Photometric analysis indicates that Gaia23bab is a class II source with age ≲1 Myr, spectral type G3−K0, stellar luminosity ∼4.0 L
⊙, and mass ∼1.6 M
⊙. The optical/near-infrared spectrum is rich in emission lines. From the analysis of these lines we measured an accretion luminosity and mass accretion rate (L

Anxiety conditions and disorders are common in the general population, and patients suffering from them often seek the services of emergency departments. Anxiety is a psychopathological symptom that accompanies not only psychiatric conditions, but a wide range of somatic diseases, and a combination of both. The biochemical and pathophysiological mechanisms of psychosomatic interrelationship and comorbidity are complex and multi-layered. Thus, diagnosing the root cause of anxiety is a clinical challenge. Early, and on time, recognition of an anxiety disorder helps to avoid unnecessary investigations, ensures correct treatment and saves hospital resources. Careful use of medications, psychoeducation and referral to a specialist improves patient outcome with this potentially debilitating disease.
In this article, the authors aim to present in a synthesized form the main epidemiological data on the prevalence of anxiety symptoms and disorders, anatomical localization and biochemical mechanisms and relationships in the pathogenesis of anxiety symptoms, as well as to derive the main guidelines for recognizing and differentiating clinicopathological constellations in somatic conditions in emergency medical practice.
Materials and methods. Existing published studies from an international database, related to the subject of the article, have been thoroughly studied.
Results. Anxiety symptoms, in particular panic attacks and disorders, are widespread in primary care and occupy a significant part of the work process, especially at times of peak loads, natural disasters and situations of mass traumatism.
Conclusions. Timely training and good preparation for recognition and adequate assessment of anxiety conditions in primary and emergency medical care significantly shorten the therapeutic route of patients. They receive competent help on time, and the cost of their treatment is significantly reduced.
Discussion. Modern medical science, including psychiatric, offers advanced drug and non-drug methods for the treatment and prevention of anxiety conditions and disorders.

A large-scale high-resolution numerical model for sea-ice fragmentation dynamics

Published: May 2024

Abstract. Forecasts of sea-ice motion and fragmentation are of vital importance for all human interactions with sea ice, ranging from those involving indigenous hunters to shipping in polar regions. Sea-ice models are also important for simulating long-term changes in a warming climate. Here, we apply the Helsinki Discrete Element Model (HiDEM), originally developed for glacier calving, to sea-ice breakup and dynamics. The code is highly optimized to utilize high-end supercomputers to achieve an extreme time and space resolution. Simulated fracture patterns and ice motion are compared with satellite images of the Kvarken region of the Baltic Sea from March 2018. A second application of HiDEM involves ice ridge formation in the Gulf of Riga. With a few tens of graphics processing units (GPUs), the code is capable of reproducing observed ice patterns that in nature may take a few days to form; this is done over an area of ∼100km×100km, with an 8 m resolution, in computations lasting ∼10 h. The simulations largely reproduce observed fracture patterns, ice motion, fast-ice regions, floe size distributions, and ridge patterns. The similarities and differences between observed and computed ice dynamics and their relation to initial conditions, boundary conditions, and applied driving forces are discussed in detail. The results reported here indicate that the HiDEM has the potential to be developed into a detailed high-resolution model for sea-ice dynamics at short timescales, which, when combined with large-scale and long-term continuum models, may form an efficient framework for forecasts of sea-ice dynamics.
