Background: The perceived language barrier in English is said to hinder, and in certain instances, impede the global dissemination of knowledge, including medical information, to non-native English speakers within medical institutions. As English for medical purposes instructors, we contend that the issue persists in medical universities across various EFL contexts. Medical students face the challenge of presenting their research findings in English for international journals and conferences. Given this, the present research study aimed to compile a comprehensive catalog of high-frequency errors and examine them in recurring linguistic patterns commonly found in the writing of Iranian medical students.
Methods: In conducting the present study, we developed a learner corpus of 1,040 essays (339,040 words and 18,235 sentences in total). Through using the results obtained from Wordsmith Tools 8 and sifting the leaner corpus, we identified 11 high-frequency errors and five commonly used linguistic patterns.
Results: Only five out of 11 high-frequency errors account for 61% of the total number of errors. Results also showed that a majority of errors were of grammatical nature. In this regard, cohesion and cohesive devices (16%) were the most prevalent errors followed by omission/misusing of articles/determiners (14%). Additionally, results showed that discourse markers were extensively used in the corpus (22.07%), followed by hedges (11.42%).
Conclusions: The outcomes of this study are expected to assist English for medical purposes instructors in designing focused lesson plans and classroom activities. Ultimately, these efforts might contribute to enhancing medical education in non-English speaking universities.

This study establishes a quantitative framework using field observations and normal mode theory to reveal wind field control mechanisms over ambient noise vertical directionality in shallow water. Acoustic data from a vertical line array in the northern South China Sea, combined with sound speed profiles, seabed properties, and multi-source wind fields (ERA5 reanalysis/Weibull-distributed synthetics), demonstrate: (1) A 20-km spatial noise-energy threshold (>90% energy contribution), challenging conventional near-field assumptions (1-2 km); (2) frequency-dependent distribution: low-frequency (50-200 Hz) directionality depends on near-field sources, while high-frequency (>400 Hz) energy shifts seaward due to modal cutoff variations; (3) model validation shows 0.96 correlation at 100 Hz/100 km (stratified medium accuracy), but seabed interface waves induce 3.

This study evaluated the agreement between markerless motion capture and criterion methods for estimating mechanical work (external and internal) performed during tennis strokes. Sixteen tennis players performed 10 serve, forehand and backhand movements whilst motion data were captured concurrently with a custom 3D markerless system (utilising open-source pose estimation; HRNet and OpenPose) and two criterion methods: marker-based motion capture and ground reaction forces. Centre of mass kinetic and potential energy were calculated and used to compute external mechanical work from all methods, whilst segment kinetic energies were calculated and used to compute internal mechanical work from the kinematic approaches only.

Neural operators have emerged as powerful surrogates for modeling complex physical problems. However, they suffer from spectral bias making them oblivious to high-frequency modes, which are present in multiscale physical systems. Therefore, they tend to produce over-smoothed solutions, which is particularly problematic in modeling turbulence and for systems with intricate patterns and sharp gradients such as multi-phase flow systems.

For individuals with agrammatic aphasia, producing sentences with non-canonical word orders is a challenging feat. Studies on different languages report deficits in this area of sentence production: some citing problems related to retrieval of verb morphology while others pursue a more holistic approach by attributing the root of the deficit towards the process of thematic role assignment. It has been shown that agrammatic speakers of Standard Indonesian are relatively unimpaired in the use (in spontaneous speech) and comprehension of passive constructions.

The quantification of movable shale oil is crucial for the effective exploration and development of shale oil resources. Nuclear magnetic resonance (NMR), a nondestructive and noninvasive technique, has become an indispensable tool for evaluating movable oil saturation. However, the small core sizes, high-frequency instrumentation, costly measurements, and significant losses of light hydrocarbons pose substantial challenges in accurately assessing movable oil.
