n order to make attribute grammars useful for complicated analysis tasks, a number of extensions to the original Knuth formalism have been suggested. One such extension is the collection attribute mechanism, which allows the value of an attribute to be defined as a combination of contributions from distant nodes in the abstract syntax tree. Another extension that has proven useful is circular attr
This paper investigates the explanatory power of development, prosperity and regulatory capability as proximate causes of non-indigenous species (NIS) occurrence in different countries, doing this by statistically analysing a global cross-sectional data set. Since the quantification of development is subject to much discussion, two different indicators are tested: gross domestic product (GDP) per
Apart from being applied as an energy carrier, hydrogen is in increasing demand as a commodity. Currently, the majority of hydrogen (H2) is produced from fossil fuels, but from an environmental perspective, sustainable H2 production should be considered. One of the possible ways of hydrogen production is through fermentation, in particular, at elevated temperature, i.e. thermophilic biohydrogen pr
Techniques for searching for good quasi-cyclic (QC) LDPC block codes of short and moderate lengths which are suitable for practical purposes are studied. To facilitate implementations only codes whose parity-check matrices having bidiagonal structure of their submatrices and consequently having low encoding complexity are considered. The problem of finding QC LDPC codes with the near-optimum frame
It is a well known fact that since the 1960s, Sweden and Holland have developed completely different types of drug policy. But there are a number of misconceptions as to what the differences consist in and how they have arisen. My contribution to this anthology involves elucidating these differences. In the context of international discussions of drug policy, the policies followed by Sweden and Ho
Plasmodium falciparum dihydroorotate dehydrogenase (PfDHODH) has been clinically validated as a target for antimalarial drug discovery, as a triazolopyrimidine class inhibitor (DSM265) is currently undergoing clinical development. Here, we have identified new hydroxyazole scaffold-based PfDHODH inhibitors belonging to two different chemical series. The first series was designed by a scaffold hoppi
The determination of the CP nature of the Higgs coupling to top quarks is addressed in this paper, using tt-h events produced in s=13 TeV proton-proton collisions at the LHC. Dileptonic final states are employed, with two oppositely charged leptons and four jets, corresponding to the decays t→bW+→b+ν, t-→b-W-→b--ν-, and h→bb-. Pure scalar (h=H), pure pseudoscalar (h=A), and CP-violating Higgs boso
One of the aims of outdoor lighting in public spaces, such as pathways and subsidiary roads, is to help pedestrians to evaluate the intentions of other people. This paper discusses how a pedestrians' appraisal of another persons' intentions in artificially lit outdoor environments can be studied. We review the visual cues that might be used, and the experimental design with which effects of change
An analysis on selecting cutting speed, cutting feed and depth of cut when collecting data for the Colding Tool Life Model based on Woxen's Equivalent Chip Thickness was performed to achieve the lowest possible model error. All possible combinations of a large data set were evaluated with regard to model error. This work shows that an increase of ratio between the highest and lowest cutting speed,
(Z, Z)-3, 9-cis-6, 7-Epoxyheptadecadiene, and (Z, Z)-6, 9-cis-3, 4-epoxyheptadecadiene were identified by gas chromatography/flame ionization detection-electroantennographic detection (GC/FID-EAD) and coupled gas chromatography-mass spectrometry (GC-MS) from abdominal tip extracts of Tephrina arenacearia (Lepidoptera: Geometridae), an alfalfa pest. In gas chromatography/flame ionization—single sen
The conflict-driven clause learning (CDCL) paradigm has revolutionized SAT solving over the last two decades. Extending this approach to pseudo-Boolean (PB) solvers doing 0-1 linear programming holds the promise of further exponential improvements in theory, but intriguingly such gains have not materialized in practice. Also intriguingly, most PB extensions of CDCL use not the division rule in cut
We present a new analog-to-digital converter (ADC)-based architecture of a phase-tracking receiver (PT-RX) optimized for ultra-low-power (ULP) and ultra-low-voltage (ULV) operations for the Internet of Things (IoT). The RX employs a type-II loop configuration that offers improved stability compared with the previous type-I PT-RX solutions. In addition, the type-II loop is also very tolerant of lon
Conflict-driven pseudo-Boolean solvers optimize 0-1 integer linear programs by extending the conflict-driven clause learning (CDCL) paradigm from SAT solving. Though pseudo-Boolean solvers have the potential to be exponentially more efficient than CDCL solvers in theory, in practice they can sometimes get hopelessly stuck even when the linear programming (LP) relaxation is infeasible over the real
Hayek sees poverty in its absolute sense as a factual problem, which the society has an obligation to deal with. Relative poverty, on the other hand, is not a problem with which the state should be concerned. Hayek approves the use of redistribution to decrease absolute poverty. However, redistribution of income for the sake of greater material equality would necessarily imply unequal treatment of
Should parents aim to make their children as normal as possible to increase their chances to "fit in"? Are neurological and mental health conditions a part of children's identity and if so, should parents aim to remove or treat these? Should they aim to instil self-control in their children? Should prospective parents take steps to insure that, of all the children they could have, they choose the
A variety of alkyl and aryl glycosides were investigated as substrates for almond β-glucosidase catalysed synthesis of hexyl-β-D-glycosides in low aqueous hexanol media. The rate-limiting step in the organic media was determined to be the glycosylation of the enzyme. The kinetic constants V max , K m (glycosyl donor) and V max /K m were all influenced by the water activity and they all increased
