text: No catalyst required! A highly efficient, catalyst-free process to generate
diimide in situ from hydrazine monohydrate and molecular oxygen for the selective
reduction of alkenes has been developed. The use of a gas–liquid segmented flow
system allowed safe operating conditions and dramatically enhanced this atom-economical
reaction, resulting in short processing times.

text: It's not magic! The effects observed in microwave-irradiated chemical transformations
can in most cases be rationalized by purely bulk thermal phenomena associated
with rapid heating to elevated temperatures. As discussed in this Essay, the existence
of so-called nonthermal or specific microwave effects is highly doubtful.

text: Near-surface air temperature, typically measured at a height of 2 m, is the
most important control on the energy exchange and the melt rate at a snow or ice
surface. It is distributed in a simplistic manner in most glacier melt models
by using constant linear lapse rates, which poorly represent the actual spatial
and temporal variability of air temperature. In this paper, we test a simple thermodynamic
model proposed by Greuell and Böhm in 1998 as an alternative, using a new dataset
of air temperature measurements from along the flowline of Haut Glacier d’Arolla,
Switzerland. The unmodified model performs little better than assuming a constant
linear lapse rate. When modified to allow the ratio of the boundary layer height
to the bulk heat transfer coefficient to vary along the flowline, the model matches
measured air temperatures better, and a further reduction of the root-mean-square
error is obtained, although there is still considerable scope for improvement.
The modified model is shown to perform best under conditions favourable to the
development of katabatic winds – few clouds, positive ambient air temperature,
limited influence of synoptic or valley winds and a long fetch – but its performance
is poor under cloudy conditions.

text: Parameterizations of incoming longwave radiation are increasingly receiving
attention for both low and high elevation glacierized sites. In this paper, we
test 13 clear-sky parameterizations combined with seven cloud corrections for
all-sky atmospheric emissivity at one location on Haut Glacier d'Arolla. We also
analyze the four seasons separately and conduct a cross-validation to test the
parameters’ robustness. The best parameterization is the one by Dilley and O'Brien,
B for clear-sky conditions combined with Unsworth and Monteith cloud correction.
This model is also the most robust when tested in cross-validation. When validated
at different sites in the southern Alps of Switzerland and north-western Italian
Alps, all parameterizations show a substantial decrease in performance, except
for one site, thus suggesting that it is important to recalibrate parameterizations
of incoming longwave radiation for different locations. We argue that this is
due to differences in the structure of the atmosphere at the sites. We also quantify
the effect that the incoming longwave radiation parameterizations have on energy-balance
melt modeling, and show that recalibration of model parameters is needed. Using
parameters from other sites leads to a significant underestimation of melt and
to an error that is larger than that associated with using different parameterizations.
Once recalibrated, however, the parameters of most models seem to be stable over
seasons and years at the location on Haut Glacier d'Arolla.

text: Greater Himalayan glaciers are retreating and losing mass at rates comparable
to glaciers in other regions of the world1,2,3,4,5. Assessments of future changes
and their associated hydrological impacts are scarce, oversimplify glacier dynamics
or include a limited number of climate models6,7,8,9. Here, we use results from
the latest ensemble of climate models in combination with a high-resolution glacio-hydrological
model to assess the hydrological impact of climate change on two climatically
contrasting watersheds in the Greater Himalaya, the Baltoro and Langtang watersheds
that drain into the Indus and Ganges rivers, respectively. We show that the largest
uncertainty in future runoff is a result of variations in projected precipitation
between climate models. In both watersheds, strong, but highly variable, increases
in future runoff are projected and, despite the different characteristics of the
watersheds, their responses are surprisingly similar. In both cases, glaciers
will recede but net glacier melt runoff is on a rising limb at least until 2050.
In combination with a positive change in precipitation, water availability during
this century is not likely to decline. We conclude that river basins that depend
on monsoon rains and glacier melt will continue to sustain the increasing water
demands expected in these areas10.

text: We investigate the sensitivity of a distributed enhanced temperature-index
(ETI) melt model, in order to understand which parameters have the largest influence
on model outputs and thus need to be accurately known. We use melt and meteorological
data from two Alpine glaciers and one glacier in the Andes of Chile. Sensitivity
analysis is conducted in a systematic way in terms of parameters and the different
conditions (day, night, clear-sky, overcast), melt seasons and glaciers examined.
The sensitivity of total melt to changes in individual parameters is calculated
using a local method around the optimal value of the parameters. We verify that
the parameters are optimal at the distributed scale and assess the model uncertainty
induced by uncertainty in the parameters using a Monte Carlo technique. Model
sensitivity to parameters is consistent across melt seasons, glaciers, different
conditions and the daily statistics examined. The parameters to which the model
is most sensitive are the shortwave-radiation factor, the temperature lapse rate
for extrapolation of air temperature, the albedo parameters, the temperature threshold
and the cloud transmittance factor parameters. A parameter uncertainty of 5% results
in a model uncertainty of 5.6% of mean melt on Haut Glacier d’Arolla, Switzerland.

text: When confronted with a large-field stimulus rotating around the vertical body
axis, flies display a following behavior called "optomotor response."
As neural control elements, the large tangential horizontal system (HS) cells
of the lobula plate have been prime candidates for long. Here, we applied optogenetic
stimulation of HS cells to evaluate their behavioral role in Drosophila. To minimize
interference of the optical activation of channelrhodopsin-2 with the visual perception
of the flies, we used a bistable variant called ChR2-C128S. By applying pulses
of blue and yellow light, we first demonstrate electrophysiologically that lobula
plate tangential cells can be activated and deactivated repeatedly with no evident
change in depolarization strength over trials. We next show that selective optogenetic
activation of HS cells elicits robust yaw head movements and yaw turning responses
in fixed and tethered flying flies, respectively.

text: In the fly Drosophila melanogaster, photoreceptor input to motion vision is
split into two parallel pathways as represented by first-order interneurons L1
and L2 (Rister et al., 2007; Joesch et al., 2010). However, how these pathways
are functionally specialized remains controversial. One study (Eichner et al.,
2011) proposed that the L1-pathway evaluates only sequences of brightness increments
(ON-ON), while the L2-pathway processes exclusively brightness decrements (OFF-OFF).
Another study (Clark et al., 2011) proposed that each of the two pathways evaluates
both ON-ON and OFF-OFF sequences. To decide between these alternatives, we recorded
from motionsensitive neurons in flies in which the output from either L1 or L2
was genetically blocked. We found that blocking L1 abolishes ON-ON responses but
leaves OFF-OFF responses intact. The opposite was true, when the output from L2
was blocked. We conclude that the L1 and L2 pathways are functionally specialized
to detect ON-ON and OFF-OFF sequences, respectively.

text: We derive sufficient conditions for advection-driven backward motion of the
free boundary in a chemotaxis model with degenerate mobility. In this model, a
porous-medium-type diffusive term and an advection term are in competition. The
former induces forward motion, the latter may induce backward motion of the free
boundary depending on the direction of advection. We deduce conditions on the
growth of the initial data at the free boundary which ensure that at least initially
the advection term is dominant. This implies local backward motion of the free
boundary provided the advection is (locally) directed appropriately. Our result
is based on a new class of moving test functions and Stampacchia's lemma. As a
by-product of our estimates, we obtain quantitative bounds on the spreading of
the support of solutions for the chemotaxis model and provide a proof for the
finite speed of the support propagation property of solutions.
