Noise colour and the risk of population extinctions
A recurrent problem in ecology and conservation biology is to estimate the risk of population extinctions. Extinction probabilities are not only imperative for conservation and management, but may also elucidate basic mechanisms of the regulation of natural populations. The usual way of modelling stochastic influence on population dynamics has been to assume that the external noise is uncorrelated
Red, blue and green : Dyeing population dynamics
Numbers or densities of a natural population typically change over time. These fluctuations result from density-dependence mechanisms in the populations or external environmental variations. According to modern ecological research, time series describing population sizes and physical environments tend to be dominated by low-frequency fluctuations, whereas, contrary to this, simple population dynam
Flee or fight uncertainty : Plant strategies in relation to anticipated damage
In order to cope with damage, plants have evolved a number of strategies. We incorporate two of those strategies, compensatory regrowth and escaping damage in time, into a mathematical model in an attempt to outline under what circumstances one or the other of these phenotypic traits will evolve. Escaping damage in time is accomplished by flowering and setting seeds at a point of time when the ris
Experimental Uncertainties of the Heat Flux Method for Measuring Burning Velocities
The laminar burning velocity is a fundamental property of combustiblemixtures important for kinetic model validation as well as for practicalapplications. Many efforts are directed towards its accurate determination.The heat flux method is one of the commonly recognized methodsfor measuring laminar burning velocity, however, the information on theaccuracy of the method is scattered in the literatu

Art ventures as hybrid organisations: Tensions and conflicts relating to organisational identity
Research indicates that hybrid ventures face more complexchallenges than other ventures, due to multiple institutional logics. Institutionallogics theory suggests that this is due to different institutional backgrounds thatinfluence actor perspectives and expectations on decision making authority andventure identity, which in turn result in tensions and possible conflicts,especially over time. The
Robust time-of-arrival self calibration and indoor localization using Wi-Fi round-trip time measurements
The problem of estimating receiver-sender node positions from measured receiver-sender distances is a key issue in different applications such as microphone array calibration, radio antenna array calibration, mapping and positioning using UWB and mapping and positioning using round-trip-time measurements between mobile phones and Wi-Fi-units. Thanks to recent research in this area we have an incre

Cultivating awareness at school. Effects on effortful control, peer relations and well-being at school in grades 5, 7, and 8
Effects of a mindfulness-based program, Compassion and Attention in the Schools (Compas), were studied in 358 pupils in grades 5, 7, and 8 in Sweden. An experimental group undertook Compas practices in class three times a week during an eight-week period. A control group undertook content area academic lessons .

Amine transaminase: Process development aspects for chiral amine synthesis
Many modern drugs contain chiral amine moieties and the need for more efficient processes to synthesize these amines in high optical purity and concentration are greatly demanded by the fine chemical and pharma industry. Amine transaminases (ATA) allow for the direct asymmetric synthesis of optically pure amines from ketone substrates. Although academia and industry have been researching ATAs exte
Optimized physical broadcast channel reception
A receiver receives information from a physical broadcast channel signal, wherein the receiver includes a blind processing and decoding unit that utilizes a hypothesis about how many transmit antennas were used to transmit the signal. Received signal characteristics are detected that indicate how many transmit antennas were used.

Network Requirements for Latency-Critical Services in a Full Cloud Deployment
The end-point of the cloud trend is that all compu- tational and storage resources leave the homes and move to the cloud. We can be rather certain the future eventually looks like this as IT and telecommunications services are commoditised and the end users’ time, interest and skill to acquire and maintain electronics fade away. The network architecture suitable for such scenario will be analysed

G-CSF prevents caspase 3 activation in Schwann cells after sciatic nerve transection, but does not improve nerve regeneration
Exogenous granulocyte-colony stimulating factor (G-CSF) has emerged as a drug candidate for improving the outcome after peripheral nerve injuries. We raised the question if exogenous G-CSF can improve nerve regeneration following a clinically relevant model - nerve transection and repair - in healthy and diabetic rats. In short-term experiments, distance of axonal regeneration and extent of injury
