An n-p-n transistor at room temperature is configured with its emitter disconnected. A voltage of \( 10 \, \text{V} \) is applied between the collector and base, with the collector being positive. Under this condition, a current of \( 0.25 \, \mu\text{A} \) flows. When the base is disconnected and the same voltage is applied between the collector and emitter, the current increases to \( 25 \, \mu\text{A} \). Determine the values of \( \alpha \), \( I_E \), and \( I_B \) if the collector current is \( 1 \, \text{mA} \).
