Attending to classroom activities on time is the primary method in traditional educational institutions to conduct knowledge to students. This method of taking attendance is tedious and vulnerable to dishonesty. Our project goal is to develop clean devices using state-of-the-art biometric technology to make class-time more productive. Governing design factors of proposed system is privacy, security, mobility, and energy efficiency. Privacy and security is maintained by using an algorithm to maintain identity of a fingerprint without capturing any images. Mobility is enabled using Wi-Fi connectivity. Power efficiency is achieved by utilizing effective power management schemes. Based on our experience in CAPPLab, this device has potential of expansion into assisting organizations in managing security and privacy.

Background: Primary mucinous adenocarcinoma of the skin is a rare malignant sweat gland tumor, which is difficult to distinguish from metastatic adenocarcinoma. Purpose: Describe a case of mucinous adenocarcinoma of the scalp and discuss the usefulness of immunohistochemical techniques in the diagnosis of primary vs. metastatic mucinous adenocarcinoma. Case Report: A 58 year old female presented with a cyst on her scalp, which was initially diagnosed as a metastatic mucinous adenocarcinoma. After radiological evaluation the malignancy was determined to be a primary mucinous adenocarcinoma of the scalp. Treatment included wide excision and radiation therapy with no recurrence or metastasis on follow up. Conclusion: This case report describes challenges in the diagnosis of primary vs. metastatic mucinous adenocarcinoma of the skin.

There is growing interest in whether invasive species may be controlled by targeting key life stages. In this study, I test whether fire applied at potentially vulnerable life stages can increase mortality and limit the spread of the invasive legume, sericea. Although laboratory experiments indicated that fire inflicted extremely high mortality on sericea seeds, fire enhanced germination rates in the field suggesting that seeds may be protected from fire by mixing with soil. Furthermore, fire had little effect on seedling survival even for very young plants. This suggests that sericea seedlings may quickly reach a size from which they are capable of resprouting. These results illustrate that, although certain life stages are presumed to be vulnerable to disturbance, such untested assumptions can result in unanticipated outcomes due to interactions between biotic and abiotic factors.

Grammar, the order and coordination of words in the English language, is essential to useful and elegant communication. This study addresses the effect of teacher feedback on student writing. Three groups of five freshmen students wrote three essays, and following teacher critique, revised the writing. Each group received different styles of feedback: explicit grammar corrections within the text, marginal notes without specific correction, or narrative teacher response. The results showed that all students improved their writing, but the group receiving a narrative response from the teacher developed a higher level of ideas and organizational structure within their writing.
