Conventional acetone-butanol-ethanol (ABE) fermentation is severely limited by low solvent titer and productivities. Thus, this study aims at developing an improved Clostridium acetobutylicum strain possessing enhanced ABE production capability followed by process optimization for high ABE productivity. Random mutagenesis of C. acetobutylicum PJC4BK was performed by screening cells on fluoroace...

We propose adaptively secure attribute-based encryption (ABE) schemes for boolean formulas over large universe attributes from the decisional linear (DLIN) assumption, which allow attribute reuse in an available formula without the previously employed redundant multiple encoding technique. Thus our KP-(resp. CP-)ABE has non-redundant ciphertexts (resp. secret keys). For achieving the results, w...

The prothrombinase complex converts prothrombin to α-thrombin through the intermediate meizothrombin (Mz-IIa). Both α-thrombin and Mz-IIa catalyze factor (F) XI activation to FXIa, which sustains α-thrombin production through activation of FIX. The interaction with FXI is thought to involve thrombin anion binding exosite (ABE) I. α-Thrombin can undergo additional proteolysis to β-thrombin and γ...

Traditionally, in attribute-based encryption (ABE), an access structure is constructed from a linear secret sharing scheme (LSSS), a boolean formula or an access tree. In this work, we encode the access structure as their minimal sets, which is equivalent to the existence of a smallest monotonic span program for the characteristic function of the same access structure. We present two leakage-re...

During recovery from even a brief period of exercise, metabolic rate remains elevated above resting levels for extended periods. The intensity and duration of exercise as well as body temperature and hormone levels can influence this excess post-exercise oxygen consumption (EPOC). We examined the influence of activity before exercise (ABE), commonly termed warm-up in endotherms, on EPOC in the ...

A number of software cost estimation methods have been presented in literature over the past decades. Analogy based estimation (ABE), which is essentially a case based reasoning (CBR) approach, is one of the most popular techni...

We present simpler and improved constructions of unbounded attribute-based encryption (ABE) schemeswith constant-size public parameters under static assumptions in bilinear groups. Concretely, we obtain: – a simple and adaptively secure unbounded ABE scheme in composite-order groups, improving upon a previousconstruction of Lewko and Waters (Eurocrypt ’11) which only achieves selective ...

Readily available inexpensive substrate with high product yield is the key to restoring acetone-butanol-ethanol (ABE) fermentation to economic competitiveness. Lactose-replete cheese whey tends to favor the production of butanol over acetone. In the current study, we investigated the fermentability of milk dust powder with high lactose content, for ABE production by Clostridium acetobutylicum a...

Artificial bandwidth extension (ABE) methods have been developed to enhance the quality and intelligibility of bandlimited speech transmitted over a telephone connection. Subjective listening tests are the most reliable way of evaluating the quality of ABE, but listening tests are time-consuming and expensive to arrange. Instrumental measures have also been used to estimate the subjective quali...
