The Aristotle-Kant tradition requires that autonomous activity must originate within the self and points toward a new type of causation (different from natural efficient causation) associated with teleology. Notoriously, it has so far proven impossible to uncover a workable model of causation satisfying these requirements without an increasingly unsatisfying appeal to extra-physical elements ta...

Despite numerous attempts to mitigate code-reuse attacks, Return-Oriented Programming (ROP) is still at the core of exploiting memory corruption vulnerabilities. Most notably, in JIT-ROP, an attacker dynamically searches for suitable gadgets in executable code pages, even if they have been randomized. JIT-ROP seemingly requires that (i) code is readable (to find gadgets at run time) and (ii) ex...

Childhood tuberculosis is one of the major causes of childhood mortality and morbidity though much neglected within our National Tuberculosis Control Program. This case control study was carried out to identify the risk factors for tuberculosis among children. Cases (n=95) and controls (n=94) were selected from Directly Observed Treatment Short Course (DOTS) centers of four upazillas of Dhaka a...

One view of causation is deterministic: A causes B means that on any occasion in which A occurs, B occurs. An alternative view is that causation is probabilistic: it means that given A, the probability of B is greater than some criterion, such as the probability of B given not A. Evidence about the induction of causal relations cannot decide between these two accounts, and so we examined how pe...

Many researchers consider cancer to have molecular causes, namely mutated genes that result in abnormal cell proliferation (e.g. Weinberg 1998). For others, the causes of cancer are to be found not at the molecular level but at the tissue level where carcinogenesis consists of disrupted tissue organization with downward causation effects on cells and cellular components (e.g. Sonnenschein and S...
