PhD position on mapping ecosystem service trade-offs

The Mediterranean Institute for Biodiversity and Ecology (IMBE, Aix-Marseille University, Aix-en-Provence, France), in its Research Group "Macroecology and Biogeography of Global Change (MacroBio)" has a 36-months PhD position open for applications. The position is funded by the European Commission through the FP7 Research Project OPERAs and affiliated to the French National Scientific Research Centre (CNRS).

The topic is the broad-scale spatial mapping and quantification of ecosystem service trade-offs following from management of agro-ecosystems in the Mediterranean basin. The context of the research includes the environment (climate, land use) as well as trends in societal demands for services. Based on scientific literature, spatial databases and the outputs from a process-based ecosystem model, the candidate will analyze, quantify and map ecosystem service trade-offs. Service valuation and indicator representation methods will be developed with the IMBE team. The approach is pan-Mediterranean: a significant part of the work will therefore consist of helping to reduce gaps in data and knowledge for the sum of countries around the Mediterranean basin. 

The research group works in close interaction with international programs such as Future Earth (through its project ecoSERVICES) and science-policy interfaces such as IPBES.

The successful candidate will have completed a Masters degree (or equivalent) in one of the environmental sciences, have experience in the handling of spatial data from databases, literature and models, have knowledge of existing concepts of ecosystem services, and be able to place results in the context of the Mediterranean basin (this includes the European, as well as North African and Eastern countries). The working language is English, appropriate skills in French or another of the Mediterranean languages will be an advantage.

The position will be filled when a suitable candidate has been identified. To apply for this position, please send a letter of application, demonstrating your ability to understand the task, and your CV as soon as possible, but before the 31st of January 2013, by e-mail to Ms. Gabriela Boéri (Gabriela.Boeri@imbe.fr). For any questions about the task, working conditions, or the OPERAs project, please contact Professor Wolfgang Cramer (Wolfgang.Cramer@imbe.fr).

UNEP-WCMC: Towards a global map of natural capital

For the first time, a composite map of the world’s ecosystem assets has been produced, covering both marine and terrestrial realms. A report for the UNEP Division of Early Warning and Assessment by UNEP-WCMC presents global maps of assets such as biodiversity, freshwater resources and soil quality.

Natural capital is fundamental to human well-being. According to the Convention on Biological Diversity, at least 40 per cent of the world’s economy and 80 per cent of the needs of the poor are derived from biological resources. We are now facing a problem where natural capital has been harvested and degraded at a rate that threatens to undermine our well-being and future economic growth.

In their latest report UNEP-WCMC have combined information about key ecosystem assets into global maps covering terrestrial and marine realms. The assets included are freshwater resources, soil quality, organic carbon, terrestrial and marine biodiversity, and global fish catch (as a proxy for marine fish stocks). The report builds on a considerable body of work in the fields of natural capital accounting and the mapping of ecosystem services.

Good Morning, News: Keith Wilson is Mayor-Elect, Bernie Offers Harsh (But True) Feedback for Dems, and Lame Ducks Gonzalez and Mapps Don't Wanna Work Anymore

by Taylor Griggs

If you’re reading this, you probably know the value of the Mercurys news reporting, arts and culture coverage, event calendar, and the bevy of events we host throughout the year. The work we do helps our city shine, but we can’t do it without your support. If you believe Portland benefits from smart, local journalism and arts coverage, please consider making a small monthly contribution, because without you, there is no us. Thanks for your support! 

Good morning, Portland. I need to keep it real with you—I'm not doing too hot on an emotional level. I know I'm not alone in that feeling. But it's going to be 60 degrees and sunny out today (ahead of cold and rain for days to come) so I recommend going outside, taking a walk, trying to breathe. Now, am I going to do that? HELL NO! Just as your elementary school teachers lived in the school, I live in the computer and I cannot get out, even when it would serve me and others to do so. Okay, fine—I will try to take a short walk today. But you have to, too. I'm going to stop talking to myself now because I know what you came here for was the NEWS, not little platitudes about self-care. But, I mean, we should take care of ourselves. 

IN LOCAL NEWS: 

• THE SECOND ROUND OF CITY COUNCIL RESULTS ARE IN...and nothing has changed. Well, okay, the candidates who were leading on election night are still in good positions to win, though Multnomah County has more than 100,000 ballots left to count (and more are likely en route to the Elections Office).

Right now, it's looking like there's going to be a pretty solid progressive majority on City Council, with candidates Tiffany Koyama Lane and Mitch Green (both endorsed by the Democratic Socialists of America) in good positions to win a seat. Other notable progressive candidates in the top three of their districts include Candace Avalos (D1), Sameer Kanal (D2), and Angelita Morillo (D3). This evening's drop should bring a bit more certainty, but there's good reason for optimism.

Business poured a ton of money into these races and money was unable to compete with community, a strong ground game, and the literal power of love and friendship (yes I’m talking about me and Tiffany ????)

— Angelita for PDX (@pnwpolicyangel) November 7, 2024

BUT! I buried the lede here, because we do know one thing: Keith Wilson is going to be Portland's next mayor. Current Mayor Ted Wheeler posted his congratulations on social media, and mayoral candidate Rene Gonzalez said he conceded the race. We ranked Wilson second on our list of endorsements, and his win is a pretty resounding disapproval of our current City Council members, three of whom ran mayoral campaigns of their own. Also...our city sure has a type. 

Keith Wilson and Portland's other recent mayors. 

• Commissioners Rene Gonzelez, Mingus Mapps, and Dan Ryan have dropped their controversial, expensive plan to terminate the city's homeless services agreement with Multnomah County. Why? Well, as much as I'd like to think common sense prevailed, it seems more likely that Gonzalez and Mapps are just not in the mood for political stunts following their poor showing in Tuesday's mayoral election. The trio pulled the agenda item to consider terminating the joint homeless response agreement a little more than 24 hours before it was set to be considered by Council today.

And folks, this is a win! Terminating the Homelessness Response Services Intergovernmental Agreement between the city of Portland and Multnomah County would've cost about $40 million in cold hard cash and even more in wasted energy and political capital. Plus, with the intergovernmental agreement dissolution off the table, it's official: Gonzalez really did not do ANYTHING during his short time in Portland City Hall. (And I feel confident saying he will not be productive in his lame duck period.) No matter what happens with the new City Council, it's only uphill from here.  

Last night was a repudiation of this kind of politics. Good to pull it as 2/3 of its sponsors will not even be on the next council. I'm calling on council to also pull the Clean and Safe ESD vote from next week's agenda. Let the next council take that up. https://t.co/I0e6DXbDCB

• If you're looking for some non-election related news, our Corbin Smith has you covered with a wonderful recap and stunning photos from the Women's Flat Track Derby Association (WFTDA) Global Championship this past weekend, where Portland's roller derby squad won the day. Smith says the roller derby championship was "sports. Major sports." So READ ALL ABOUT IT RIGHT HERE

• There's really not much local news available right now that's not related to the election (which is fair and good and obviously important but I figure you guys might want to read about something else for a second of your day). But there is this: Intel is bringing back free coffee and tea for employees. This was an employee benefit it slashed during budget cuts last summer, but in an attempt to improve employee morale, it's back. The chipmaker is currently doing layoffs at its Oregon facility and has cut other, more important employee benefits that will likely not return, but I guess a cost-benefit analysis showed saving money on coffee wasn't worth the fight. If Mike Rogoway at the Oregonian deems it important, who am I to disagree? (That wasn't sarcasm, Rogoway's a great reporter.) 

IN NATIONAL/WORLD NEWS: 

• The country is reacting to the news of a second Trump presidency, and there are obviously some different takes. I took note of a few notable perspectives during the rare moments when I was able to make the outrageously difficult effort to lift my head from my pillow yesterday. Senator Bernie Sanders (of "Bernie would've won" fame) probably said it best, IMO.

Sanders wrote in a statement yesterday that "It should come as no great surprise that a Democratic Party which has abandoned working class people would find that the working class has abandoned them. While the Democratic leadership defends the status quo, the American people are angry and want change." He also acknowledged the futility of asking the "big money interests and well-paid consultants who control the Democratic Party" to "learn any real lessons from this disastrous campaign."

"Will they understand the pain and political alienation that tens of millions of Americans are experiencing? Do they have any ideas as to how we can take on the increasingly powerful Oligarchy which has so much economic and political power? Probably not," Sanders wrote. 

DAMN. That's harsh but real. I hope others will join Bernie in calling on the Democratic Party to meet the moment instead of handing their ass to the increasingly fascistic Republicans. I do believe the election results also need to fall on the MAGA fools who have sold their soul to the devil in exchange for the promise of cheaper gas, but we aren't going to win by further alienating the working class. The Democrats better start bringing something to the table, or it'll be even more Joever than it is right now. 

• Among the MANY deep concerns I have about Trump's reelection, the climate crisis ranks at the top. Trump is a known climate denier and has stated his desire to boost oil production, get rid of subsidies for electric cars, and overall do a bunch of damage to any small amount of progress we've been able to make on the climate crisis in the last four years. So I'm freaking out, because this issue isn't exactly something we have time to fuck around on. 

Something that made me feel a bit better: Clean energy analysts and activists say though a second Trump administration will make it harder to transition to renewable and clean energy, it won't make it impossible. The market has already embraced clean energy for its financial benefits and the economic devastation that climate change is and will continue to cause. And that's not changing. (Obviously, the free market is not going to solve the climate crisis, but that reality would remain the same under any capitalist president.) 

Also, there are a lot of climate activists and scientists and lawyers who are a lot smarter than I am and already planning their resistance to Trump's inevitably horrible policies. If you, too, are deeply worried about climate action under Trump, consider supporting or joining an environmental organization or law group. Also, ride your bike more. Even if it won't solve the climate crisis on its own, it'll make you feel a little better.

Now, topic change needed for my sanity. Sorry.

A federal labor judge ruled Amazon workers in Alabama should get a third chance to vote on unionizing. The first time warehouse workers at a facility in Bessemer voted about unionizing in 2021, they voted no, but labor officials ruled that Amazon influenced the vote and the result shouldn't be expected. Workers voted again in 2022, but the election was too close to call and has remained in limbo. Now, a National Labor Relations Board (NLRB) judge has ordered a third election. But Amazon, AKA Union Busters R US, will surely contest the decision and continue to stomp union activity wherever it can. And under a Trump NLBR...ugh. The doom is creeping in. Sorry. Just here to report the news. 

There's a major wildfire in Southern California, just northwest of Los Angeles, prompting evacuation orders for more than 10,000 people. Powerful winds are fanning the flames and the fire has already destroyed dozens of homes and blanketed neighborhoods in smoke. Hoping for more favorable fire-fighting conditions soon.

• Finally, there's this. Happy Thursday. TTYL.

Many people will continue struggling to come to terms with the election results, but there’s still a lot you can do:

1) Be irritable at work
2) Withdraw from people who love you/need you
3) Make an impulsive and self destructive major life decision

Mapping domain structures near a grain boundary in a lead zirconate titanate ferroelectric film using X-ray nanodiffraction

Direct measurements have been taken of nanoscale domain structure in ferroelectric lead zirconate titanate around a grain boundary. Characterizing the evolution of this structure under an electric field is critical for predicting dielectric and piezoelectric response.

Mapping domain structures near a grain boundary in a lead zirconate titanate ferroelectric film using X-ray nanodiffraction

The effect of an electric field on local domain structure near a 24° tilt grain boundary in a 200 nm-thick Pb(Zr0.2Ti0.8)O3 bi-crystal ferroelectric film was probed using synchrotron nanodiffraction. The bi-crystal film was grown epitaxially on SrRuO3-coated (001) SrTiO3 24° tilt bi-crystal substrates. From the nanodiffraction data, real-space maps of the ferroelectric domain structure around the grain boundary prior to and during application of a 200 kV cm−1 electric field were reconstructed. In the vicinity of the tilt grain boundary, the distributions of densities of c-type tetragonal domains with the c axis aligned with the film normal were calculated on the basis of diffracted intensity ratios of c- and a-type domains and reference powder diffraction data. Diffracted intensity was averaged along the grain boundary, and it was shown that the density of c-type tetragonal domains dropped to ∼50% of that of the bulk of the film over a range ±150 nm from the grain boundary. This work complements previous results acquired by band excitation piezoresponse force microscopy, suggesting that reduced nonlinear piezoelectric response around grain boundaries may be related to the change in domain structure, as well as to the possibility of increased pinning of domain wall motion. The implications of the results and analysis in terms of understanding the role of grain boundaries in affecting the nonlinear piezoelectric and dielectric responses of ferroelectric materials are discussed.

Similarity score for screening phase-retrieved maps in X-ray diffraction imaging – characterization in reciprocal space

X-ray diffraction imaging (XDI) is utilized for visualizing the structures of non-crystalline particles in material sciences and biology. In the structural analysis, phase-retrieval (PR) algorithms are applied to the diffraction amplitude data alone to reconstruct the electron density map of a specimen particle projected along the direction of the incident X-rays. However, PR calculations may not lead to good convergence because of a lack of diffraction patterns in small-angle regions and Poisson noise in X-ray detection. Therefore, the PR calculation is still a bottleneck for the efficient application of XDI in the structural analyses of non-crystalline particles. For screening maps from hundreds of trial PR calculations, we have been using a score and measuring the similarity between a pair of retrieved maps. Empirically, probable maps approximating the particle structures gave a score smaller than a threshold value, but the reasons for the effectiveness of the score are still unclear. In this study, the score is characterized in terms of the phase differences between the structure factors of the retrieved maps, the usefulness of the score in screening the maps retrieved from experimental diffraction patterns is demonstrated, and the effective resolution of similarity-score-selected maps is discussed.

Mapping of lithium ion concentrations in 3D structures through development of in situ correlative imaging of X-ray Compton scattering-computed tomography

Understanding the correlation between chemical and microstructural properties is critical for unraveling the fundamental relationship between materials chemistry and physical structures that can benefit materials science and engineering. Here, we demonstrate novel in situ correlative imaging of the X-ray Compton scattering computed tomography (XCS-CT) technique for studying this fundamental relationship. XCS-CT can image light elements that do not usually exhibit strong signals using other X-ray characterization techniques. This paper describes the XCS-CT setup and data analysis method for calculating the valence electron momentum density and lithium-ion concentration, and provides two examples of spatially and temporally resolved chemical properties inside batteries in 3D. XCS-CT was applied to study two types of rechargeable lithium batteries in standard coin cell casings: (1) a lithium-ion battery containing a cathode of bespoke microstructure and liquid electrolyte, and (2) a solid-state battery containing a solid-polymer electrolyte. The XCS-CT technique is beneficial to a wide variety of materials and systems to map chemical composition changes in 3D structures.

Deep-learning map segmentation for protein X-ray crystallographic structure determination

When solving a structure of a protein from single-wavelength anomalous diffraction X-ray data, the initial phases obtained by phasing from an anomalously scattering substructure usually need to be improved by an iterated electron-density modification. In this manuscript, the use of convolutional neural networks (CNNs) for segmentation of the initial experimental phasing electron-density maps is proposed. The results reported demonstrate that a CNN with U-net architecture, trained on several thousands of electron-density maps generated mainly using X-ray data from the Protein Data Bank in a supervised learning, can improve current density-modification methods.

Validation of electron-microscopy maps using solution small-angle X-ray scattering

The determination of the atomic resolution structure of biomacromolecules is essential for understanding details of their function. Traditionally, such a structure determination has been performed with crystallographic or nuclear resonance methods, but during the last decade, cryogenic transmission electron microscopy (cryo-TEM) has become an equally important tool. As the blotting and flash-freezing of the samples can induce conformational changes, external validation tools are required to ensure that the vitrified samples are representative of the solution. Although many validation tools have already been developed, most of them rely on fully resolved atomic models, which prevents early screening of the cryo-TEM maps. Here, a novel and automated method for performing such a validation utilizing small-angle X-ray scattering measurements, publicly available through the new software package AUSAXS, is introduced and implemented. The method has been tested on both simulated and experimental data, where it was shown to work remarkably well as a validation tool. The method provides a dummy atomic model derived from the EM map which best represents the solution structure.

Likelihood-based interactive local docking into cryo-EM maps in ChimeraX

The interpretation of cryo-EM maps often includes the docking of known or predicted structures of the components, which is particularly useful when the map resolution is worse than 4 Å. Although it can be effective to search the entire map to find the best placement of a component, the process can be slow when the maps are large. However, frequently there is a well-founded hypothesis about where particular components are located. In such cases, a local search using a map subvolume will be much faster because the search volume is smaller, and more sensitive because optimizing the search volume for the rotation-search step enhances the signal to noise. A Fourier-space likelihood-based local search approach, based on the previously published em_placement software, has been implemented in the new emplace_local program. Tests confirm that the local search approach enhances the speed and sensitivity of the computations. An interactive graphical interface in the ChimeraX molecular-graphics program provides a convenient way to set up and evaluate docking calculations, particularly in defining the part of the map into which the components should be placed.

Refinement of cryo-EM 3D maps with a self-supervised denoising model: crefDenoiser

Cryogenic electron microscopy (cryo-EM) is a pivotal technique for imaging macromolecular structures. However, despite extensive processing of large image sets collected in cryo-EM experiments to amplify the signal-to-noise ratio, the reconstructed 3D protein-density maps are often limited in quality due to residual noise, which in turn affects the accuracy of the macromolecular representation. Here, crefDenoiser is introduced, a denoising neural network model designed to enhance the signal in 3D cryo-EM maps produced with standard processing pipelines. The crefDenoiser model is trained without the need for `clean' ground-truth target maps. Instead, a custom dataset is employed, composed of real noisy protein half-maps sourced from the Electron Microscopy Data Bank repository. Competing with the current state-of-the-art, crefDenoiser is designed to optimize for the theoretical noise-free map during self-supervised training. We demonstrate that our model successfully amplifies the signal across a wide variety of protein maps, outperforming a classic map denoiser and following a network-based sharpening model. Without biasing the map, the proposed denoising method leads to improved visibility of protein structural features, including protein domains, secondary structure elements and modest high-resolution feature restoration.

MatchMaps: non-isomorphous difference maps for X-ray crystallography

Conformational change mediates the biological functions of macromolecules. Crystallographic measurements can map these changes with extraordinary sensitivity as a function of mutations, ligands and time. A popular method for detecting structural differences between crystallographic data sets is the isomorphous difference map. These maps combine the phases of a chosen reference state with the observed changes in structure factor amplitudes to yield a map of changes in electron density. Such maps are much more sensitive to conformational change than structure refinement is, and are unbiased in the sense that observed differences do not depend on refinement of the perturbed state. However, even modest changes in unit-cell properties can render isomorphous difference maps useless. This is unnecessary. Described here is a generalized procedure for calculating observed difference maps that retains the high sensitivity to conformational change and avoids structure refinement of the perturbed state. This procedure is implemented in an open-source Python package, MatchMaps, that can be run in any software environment supporting PHENIX [Liebschner et al. (2019). Acta Cryst. D75, 861–877] and CCP4 [Agirre et al. (2023). Acta Cryst. D79, 449–461]. Worked examples show that MatchMaps `rescues' observed difference electron-density maps for poorly isomorphous crystals, corrects artifacts in nominally isomorphous difference maps, and extends to detecting differences across copies within the asymmetric unit or across altogether different crystal forms.

High-transmission spectrometer for rapid resonant inelastic soft X-ray scattering (rRIXS) maps

The design and first results of a high-transmission soft X-ray spectrometer operated at the X-SPEC double-undulator beamline of the KIT Light Source are presented. As a unique feature, particular emphasis was placed on optimizing the spectrometer transmission by maximizing the solid angle and the efficiencies of spectrometer gratings and detector. A CMOS detector, optimized for soft X-rays, allows for quantum efficiencies of 90% or above over the full energy range of the spectrometer, while simultaneously offering short readout times. Combining an optimized control system at the X-SPEC beamline with continuous energy scans (as opposed to step scans), the high transmission of the spectrometer, and the fast readout of the CMOS camera, enable the collection of entire rapid resonant inelastic soft X-ray scattering maps in less than 1 min. Series of spectra at a fixed energy can be taken with a frequency of up to 5 Hz. Furthermore, the use of higher-order reflections allows a very wide energy range (45 to 2000 eV) to be covered with only two blazed gratings, while keeping the efficiency high and the resolving power E/ΔE above 1500 and 3000 with low- and high-energy gratings, respectively.
