Public announcement logic (PAL) is a paradigm case of dynamic epistemic logic, which models how agents’ epistemic states change when pieces of information are communicated publicly. PAL extends epistemic logic with the operator [A], where the intended reading of [A]φ is “After a public announcement that A, φ holds.” This logic has recently received two improvements. One improvement, studied in ...

Various extensions of public announcement logic have been proposed with quantification over announcements. The best-known extension is called arbitrary public announcement logic, APAL. It contains a primitive language construct ✷φ intuitively expressing that “after every public announcement of a formula, formula φ is true.” The logic APAL is undecidable and it has an infinitary axiomatization. ...

Compartmentalised extension prohibits the uptake of new technology thereby inhibiting agricultural growth. Extension services aimed at increased agricultural growth should have a market-led and evidence-based pluralistic advisory system that is coordinated by the government’s Agricultural and Technical Services division in response to the needs of farmers. This study sought to assess extension ...

Drawback of code-based public-key cryptosystems is that their publickey size is lage. It takes some hundreds KB to some MB for typical parameters. While several attempts have been conducted to reduce it, most of them have failed except one, which is Quasi-Dyadic (QD) public-key (for large extention degrees). While an attack has been proposed on QD public-key (for small extension degrees), it ca...

fundamentally, public services must be of high quality so as to satisfy the wants and needs of the beneficiaries. but it’s worrisome to discover that in uganda, public services provided are of poor quality due to unethical behaviors and wanting leadership. the purpose of this study is to show that transformational leadership can advance ethical culture to spur provision of quality services. a r...

BACKGROUND Basal cell carcinoma (BCC) is the most common malignancy with increasing incidence worldwide. The tumor invades surrounding tissues in an irregular pattern via subclinical and microscopic finger-like growths known as subclinical extension. Subclinical extension may be responsible for incomplete resection of the tumor. This study investigates the subclinical extension of BCC. METHOD...
