Java Mission Evaluation Workstation System
The Java Mission Evaluation Workstation System (JMEWS) is a collection of applications designed to retrieve, display, and analyze both real-time and recorded telemetry data. This software is currently being used by both the Space Shuttle Program (SSP) and the International Space Station (ISS) program. JMEWS was written in the Java programming language to satisfy the requirement of platform independence. An object-oriented design was used to satisfy additional requirements and to make the software easily extendable. By virtue of its platform independence, JMEWS can be used on the UNIX workstations in the Mission Control Center (MCC) and on office computers. JMEWS includes an interactive editor that allows users to easily develop displays that meet their specific needs. The displays can be developed and modified while viewing data. By simply selecting a data source, the user can view real-time, recorded, or test data

Sustainable development and airport surface access: the role of technological innovation and behavioural change.
Sustainable development reflects an underlying tension to achieve economic growth whilst addressing environmental challenges, and this is particularly the case for the aviation sector. Although much of the aviation-related focus has fallen on reducing aircraft emissions, airports have also been under increasing pressure to support the vision of a low carbon energy future. One of the main sources of airport-related emissions is passenger journeys to and from airports (the surface access component of air travel), which is the focus of this paper. Two aspects associated with the relationship between sustainable development and airport surface access are considered. Firstly, there is an evaluation of three technological innovation options that will enable sustainable transport solutions for surface access journeys: telepresence systems to reduce drop-off/pick-up trips, techniques to improve public transport and options to encourage the sharing of rides. Secondly, the role of behavioural change for surface access journeys from a theoretical perspective, using empirical data from Manchester airport, is evaluated. Finally, the contribution of technology and behavioural intervention measures to improvements in sustainable development are discussed
Targeting firing rate neuronal homeostasis can prevent seizures
Manipulating firing-rate neuronal homeostasis, which enables neurons to regulate their intrinsic excitability, offers an attractive opportunity to prevent seizures. However, to date, no drug-based interventions have been reported that manipulate this type of neuronal homeostatic mechanism. Here, we use a combination of Drosophila and mouse and, in the latter, both a pentylenetetrazole (PTZ) induced seizure model, and an electrically induced seizure model for refractory seizures to evaluate anticonvulsant efficacy of a novel class of anticonvulsant compounds, based on 4-tert-butyl-benzaldehyde (4-TBB). The mode-of-action includes increased expression of the firing rate homeostatic regulator PUMILIO (PUM). Knock-down of PUM expression, in Drosophila, blocks anticonvulsive effects of 4-TBB, whilst analysis of validated PUM targets in mouse brain show significant reductions following exposure to this compound. A structure-activity study identifies the active parts of the molecule and, further, shows the pyrazole analogue demonstrates highest efficacy, being active against both PTZ-, and electrically-induced, seizures. This study provides a proof-of-principle that anticonvulsant effects can be achieved through regulation of firing rate neuronal homeostasis and identifies a possible chemical compound for future development

Molecular Pharmacology of Selective Na<sub>V</sub>1.6 and Dual Na<sub>V</sub>1.6/Na<sub>V</sub>1.2 Channel Inhibitors that Suppress Excitatory Neuronal Activity Ex Vivo
Voltage-gated sodium channel (NaV) inhibitors
are used
to treat neurological disorders of hyperexcitability such as epilepsy.
These drugs act by attenuating neuronal action potential firing to
reduce excitability in the brain. However, all currently available
NaV-targeting antiseizure medications nonselectively inhibit
the brain channels NaV1.1, NaV1.2, and NaV1.6, which potentially limits the efficacy and therapeutic
safety margins of these drugs. Here, we report on XPC-7724 and XPC-5462,
which represent a new class of small molecule NaV-targeting
compounds. These compounds specifically target inhibition of the NaV1.6 and NaV1.2 channels, which are abundantly expressed
in excitatory pyramidal neurons. They have a > 100-fold molecular
selectivity against NaV1.1 channels, which are predominantly
expressed in inhibitory neurons. Sparing NaV1.1 preserves
the inhibitory activity in the brain. These compounds bind to and
stabilize the inactivated state of the channels thereby reducing the
activity of excitatory neurons. They have higher potency, with longer
residency times and slower off-rates, than the clinically used antiseizure
medications carbamazepine and phenytoin. The neuronal selectivity
of these compounds is demonstrated in brain slices by inhibition of
firing in cortical excitatory pyramidal neurons, without impacting
fast spiking inhibitory interneurons. XPC-5462 also suppresses epileptiform
activity in an ex vivo brain slice seizure model, whereas XPC-7224
does not, suggesting a possible requirement of Nav1.2 inhibition in
0-Mg2+- or 4-AP-induced brain slice seizure models. The
profiles of these compounds will facilitate pharmacological dissection
of the physiological roles of NaV1.2 and NaV1.6 in neurons and help define the role of specific channels in disease
states. This unique selectivity profile provides a new approach to
potentially treat disorders of neuronal hyperexcitability by selectively
downregulating excitatory circuits
