+                2. <strong>Methodology</strong><br>
+                We employed a dataset consisting of over 50,000 samples... The algorithm was optimized using stochastic gradient descent...<br><br>
+                3. <strong>Results</strong><br>
+                Our experiments demonstrate a significant improvement over baseline models (see Table 1). The ${item.year} publication date marks a significant milestone in this domain.
