Potentially problematic

Deep learning has made brilliant achievements in detecting colonic polyps in colonoscopy videos in recent years. However, the detection of colonic polyps in colonoscopy videos is problematic because of the complex environment of the colon and the various shapes of polyps. This paper aimed to investigate the polyp detection potential of the state-of-the-art deep learning model You Only Look Once version 7.

Vaginal CO2 laser therapy is a new treatment option for genitourinary syndrome of menopause. Its potential is particularly interesting in breast cancer survivors, where existing treatment options often are insufficient as hormonal treatment is problematic in these women.

Abnormal laryngeal structures are likely to be associated with a difficult laryngoscopy procedure. Currently, laryngeal structures can be measured by ultrasonography, however, little research has been performed on the potential role of ultrasound on the evaluation of a difficult laryngoscopy. The present study investigated the value of laryngeal structure measurements for predicting a difficult laryngoscopy.

Gene expression microarrays measure the levels of messenger ribonucleic acid (mRNA) in a sample using probe sequences that hybridize with transcribed regions. These probe sequences are designed using a reference genome for the relevant species.

Because of relatively small treatment numbers together with low adverse drug reaction (ADR) reporting rates the timely identification of ADRs affecting children and young people is problematic.

Water scarcity has many negative impacts on the environment, including lakes, rivers, wetlands, and other fresh water resources. Furthermore, water shortage makes flow management in the rehabilitation of village streams problematic. Owing to poor water resource management system and climate change India faces a persistent water shortage. Indian agriculture accounts for 90% water use due to fast track ground water depletion and poor irrigation systems. Water is a critical input into agriculture in nearly all its aspects having a determining effect on the eventual yield.

Building on work detecting errors in dependency annotation, we set out to correct local dependency errors. To do this, we outline the properties of annotation errors that make the task challenging and their existence problematic for learning. For the task, we define a feature-based model that explicitly accounts for non-relations between words, and then use ambiguities from one model to constrain a second, more relaxed model. In this way, we are successfully able to correct many errors, in a way which is potentially applicable to dependency parsing more generally. ...

Once the topography is defined, the next stage is to average EPS collected from these devices during normal and peak periods. Remember that demanding all log data at the highest speed 24x7 could, in itself, become problematic, causing a potential DOS situation with network or SIEM system overload. So realistic speeds based on networking and SIEM product restrictions must also be considered in the baseline.

Birthmarks are among the most common types of anomalies encountered by the pediatrician in practice. Moreover, they are a source of significant concern for parents regardless of whether they are associated with an underlying systemic abnormality. Pediatricians are often called upon in the neonatal period to establish the diagnosis and direct management. Recognition of the types of birthmarks that require additional evaluation or herald a potentially problematic course is essential when examining an infant.

Understanding the forces that influence natural variation within and among populations has been a major objective of evolutionary biology for decades (Csilléry et al., 2010). It can be problematic, as natural populations may have complex demographic histories: size and range changes over time can lead to bottlenecks, fusions and expansions that leave signatures on the genetic composition of the population (Avise, 2004). Detection and analysis of genetic diversity can help us to understand the molecular basis of various biological phenomena in these natural systems.

Unproven but of potential benefit. Many experts favor verapamil as the first-line preventive treatment for patients with chronic cluster headache or prolonged bouts. While verapamil compares favorably with lithium in practice, some patients require verapamil doses far in excess of those administered for cardiac disorders. The initial dose range is 40–80 mg twice daily; effective doses may be as high as 960 mg/d. Side effects such as constipation and leg swelling can be problematic. Of paramount concern, however, is the cardiovascular safety of verapamil, particularly at high doses.
