Good morning and happy election day, Portland! Obviously, drop off that ballot if you haven't yet. If you need a replacement, the county elections office can help you. If you're not sure who to vote for, here's our handy dandy election guide, which even includes a cheat sheet for you to refer to when filling out your ballot. If you’re monitoring results, let us keep you company on our live election night blog, and if you need to commiserate with others, or share a joke and a drink to ease the stress, join us in person at Mississippi Studios tonight for our free election night party!

In Local News: 

• Speaking of the election, voter turnout so far in Multnomah County is a little low. The number of ballots returned by Monday hovered below 46 percent. In the last presidential election, more than 73 percent of Multnomah County ballots were returned the day before the election. Some have speculated that Portland’s new ranked choice voting system and the sheer number of City Council candidates is slowing voters down, or dissuading them from filling out their ballot. BUT, people were a lot less busy in 2020, and if RCV is the culprit, why is Clackamas County–which isn’t using ranked voting– also seeing just 50 percent turnout by Monday? Similarly, Washington County’s elections office reports only 47 percent of ballots were returned by Monday. Maybe voters procrastinated, or maybe they’re just waiting to drop off their ballots in broad daylight, when there’s less likelihood of a ballot box getting blown up by some nut job. 

Turnout in Multnomah County as of November 4, 1 days before the election.

Current: 46% of accepted ballots (50% with returned ballots)
2020: 73%
2004-2020 average: 65%

• In other local election news, a few buildings downtown have boarded up their windows in preparation for potential election night protests. Portland police have been hyping up the potential for election-related violence for months now, creating a bit of hysteria that’s got some major companies spooked. At least one online flier inviting anarchist protest has circulated, but it’s unrelated to any particular candidate or party and more directed at general disdain for the state of the country.

• Portland City Council seems primed to overturn the city’s agreement with Multnomah County on managing homelessness. As we reported a few weeks ago, City Commissioners Rene Gonzalez, Mingus Mapps and Dan Ryan have all signaled support for dissolving the intergovernmental agreement that lays out which functions each government agency handles, in an effort to collaborate and tag-team the region’s most critical issue. The three stooges allege Multnomah County hasn’t kept up its end of the bargain, and they’ve got professional shit stirrer and County Commissioner Sharon Meieran egging them on. This week, Portland City Council will vote on whether to end the agreement. Jessica Vega Pederson, chair of the county’s Board of Commissioners, has called out the plan to kill the agreement as short-sighted, misinformed, chickenshit, and harmful to unhoused Portlanders who need a bevy of resources and services.

Regional executive leaders are united supporting a collaborative approach to addressing homelessness, and pushing back on this political stunt that includes no plan.

In National/World News:

• Attorneys for Elon Musk basically admitted that Musk’s election lottery scheme was more of a plot to boost the Republican party. When faced with charges of running an illegal election lottery, where he promised to pick a daily winner at random for a $1 million prize in an effort to get people registered to vote, attorneys said Musk never intended to use a lottery system to choose a winner. He instead planned to vet and select the right person to essentially be a cheerleader for Trump and the Republican party. Huh. Money can buy rocket ships and high-dollar attorneys, but it can’t buy intellect.

• Your black plastic spatula is slowly poisoning you. Recent reporting in The Atlantic reveals that many black plastic kitchen utensils are likely being made from recycled electronic waste, and leaching toxic chemicals into your food. The discovery was noted by a biochemist in 2018, who asserted that the high amount of flame retardants in black plastic products like spatulas signals the items were probably manufactured with recycled electronic parts used in computers and TVs. Because plastic is prone to leaching chemicals when it’s heated, researchers theorize it’s likely that black plastic cookware is releasing harmful compounds into cooking oil and hot foods. Might also be time to rethink all the plastic carryout containers used to store and reheat hot foods. ☣️????

An anonymous assistant to President Putin has had a few meetings with winter sports coaches, during which he "in a mild form" recommended to refuse from participating in the Olympic Games in Pyeongchang. According to All Sports agency, an official from the Kremlin administration, whose name remains anonymous, specified that it would have to be the athletes themselves to make such a decision. The talks of the of the International Olympic Committee (IOC) commission with representatives of the Russian Olympic Committee (ROC) took place in Moscow this week. The meetings were devoted to the structure of the Russian delegation during the Games in South Korea. The next day it became known that a number of prominent Russian athletes with an unblemished reputation, including biathlete Anton Shipulin, skier Sergei Ustyugov and speed skater Victor An, as well as the leaders of hockey and speed skating teams were not invited to the competitions, even though those athletes were not listed either in Richard McLaren or Denis Oswald reports. On Tuesday, the press service of the Russian Ice Skating Federation said that the IOC did not allow Russian figure skaters Ksenia Stolbova and Ivan Bukin to participate in the 2018 Winter Games without explaining the reasons. Representatives for the Russian Ice Skating Federation expressed their indignation about the absurd decision and started to defend the honour and dignity of athletes in all possible ways.The Russian Olympic Committee prepares to give a hard estimate to IOC's actions and request appropriate explanations.Following those events, Russian politicians assumed that the IOC was pushing Russia to boycott the Winter Games 2018 and exit the Olympic movement."If no explanations follow, perhaps Russian athletes will have to revise their decision regarding the participation in the Olympics in Pyeongchang. They wanted to make us boycott the Games before, but as soon as they realised that we were not going to do it, they decided to suspend clean athletes with perfect reputations. This looks like political blackmail and creates conditions for unfair victories at the Olympics," chairman of the State Duma Committee on Physical Culture Mikhail Degtyarev told Sport Express newspaper. On December 5, the IOC Executive Committee decided that only clean Russian athletes would be able to perform at the 2018 Winter Olympics in Pyeongchang under the Olympic flag. Two special committees of the IOC have reduced the list of 500 applicants to 389 names so far. The final structure of the Russian delegation will be announced on January 28.

Photo credits: Wikipedia/Faren29/CC BY-SA 4.0 By Romer Cherubim, UK Anthony Joshua lost his four heavyweight boxing titles on 01 June in spectacular fashion against Andy Ruiz Jr. at Madison Square Garden, NYC, USA. Eddie Hearn's master plan to introduce Joshua to the American public and make him look good, failed. Hearn did everything in his power to help Joshua to win his first defence of his heavyweight crown on American soil. By selecting Andy Ruiz Jr. as Joshua's next opponent, with Ruiz Jr. having only six weeks' notice of the fight, Hearn was convinced that Joshua was guaranteed an easy pay day. However, the likeable Ruiz Jr. tore up the script and proved all doubters wrong by producing a skillful display of boxing and sticking to a workable game plan. This was not a one punch wonder.

By the 2020s, in spite of centuries after the Emancipation Proclamation (in 1863) and decades or generations of Black empowerment, there is still something fundamentally missing in the Black American identity, because the latter has failed to substantially "de-colonize" the violent colonial legacy (like the ruthless importation of Black slaves, not just the near-extermination of Native Americans) in the Thirteen British Colonies (and later the United States) in early American history. A good beginning for a long-term solution (de-colonization) is to understand in what ways the "average" Black American mindset has lost its average Black "African" roots, with the resultant effect of "inferiority complex" among Black Americans (involving both "self-hatred" within the oppressed and "anger" or "hatred" towards the oppressor, which vary in degree from person to person), on "average." Although this essay uses the case of Black Americans for analysis, the logical implication is much broader, since the same reasoning can be applied to Black communities around the world (outside sub-Saharan Africa), be they in Central America, South America, the Caribbean, Northern Europe, Southern Europe, North Africa, the Oceania, and the like.

The title compound was synthesized by the condensation between tri­fluoro­methyl­aniline and di­chloro­salicyl­aldehyde by nucleophilic addition, forming a hemiaminal, followed by a dehydration to generate an imine. The compound crystallizes in an ortho­rhom­bic Pbca (Z = 8) space group with a dihedral angle of 44.70 (5)° between the two aromatic rings. In the crystal, the mol­ecules pack together to form a zigzag pattern along the c axis.

The hydro­thermal synthesis and structural characterization of four novel 3D pillared-layer metal–organic frameworks are studied, revealing how the malleability of copper coordination geometries drives diverse supramolecular isomerism.

Low-concentration poly(ethylene oxide) exhibit the polymorph-dependent effects on both the surface and bulk crystal growth of carbamazepine polymorphs. These polymorph-dependent effects of PEO were mainly attributed to the polymer enrichment at the interface and different crystal surface-polymer interactions.

Accurate modeling of conformational energies is key to the crystal structure prediction of conformational polymorphs. Focusing on molecules XXXI and XXXII from the seventh blind test of crystal structure prediction, this study employs various electronic structure methods up to the level of domain-local pair natural orbital coupled cluster singles and doubles with perturbative triples [DLPNO-CCSD(T1)] to benchmark the conformational energies and to assess their impact on the crystal energy landscapes. Molecule XXXI proves to be a relatively straightforward case, with the conformational energies from generalized gradient approximation (GGA) functional B86bPBE-XDM changing only modestly when using more advanced density functionals such as PBE0-D4, ωB97M-V, and revDSD-PBEP86-D4, dispersion-corrected second-order Møller–Plesset perturbation theory (SCS-MP2D), or DLPNO-CCSD(T1). In contrast, the conformational energies of molecule XXXII prove difficult to determine reliably, and variations in the computed conformational energies appreciably impact the crystal energy landscape. Even high-level methods such as revDSD-PBEP86-D4 and SCS-MP2D exhibit significant disagreements with the DLPNO-CCSD(T1) benchmarks for molecule XXXII, highlighting the difficulty of predicting conformational energies for complex, drug-like molecules. The best-converged predicted crystal energy landscape obtained here for molecule XXXII disagrees significantly with what has been inferred about the solid-form landscape experimentally. The identified limitations of the calculations are probably insufficient to account for the discrepancies between theory and experiment on molecule XXXII, and further investigation of the experimental solid-form landscape would be valuable. Finally, assessment of several semi-empirical methods finds r2SCAN-3c to be the most promising, with conformational energy accuracy intermediate between the GGA and hybrid functionals and a low computational cost.

Brucella ovis is an etiologic agent of ovine epididymitis and brucellosis that causes global devastation in sheep, rams, goats, small ruminants and deer. There are no cost-effective methods for the worldwide eradication of ovine brucellosis. B. ovis and other protein targets from various Brucella species are currently in the pipeline for high-throughput structural analysis at the Seattle Structural Genomics Center for Infectious Disease (SSGCID), with the aim of identifying new therapeutic targets. Furthermore, the wealth of structures generated are effective tools for teaching scientific communication, structural science and biochemistry. One of these structures, B. ovis leucine-, isoleucine-, valine-, threonine- and alanine-binding protein (BoLBP), is a putative periplasmic amino acid-binding protein. BoLBP shares less than 29% sequence identity with any other structure in the Protein Data Bank. The production, crystallization and high-resolution structures of BoLBP are reported. BoLBP is a prototypical bacterial periplasmic amino acid-binding protein with the characteristic Venus flytrap topology of two globular domains encapsulating a large central cavity containing the peptide-binding region. The central cavity contains small molecules usurped from the crystallization milieu. The reported structures reveal the conformational flexibility of the central cavity in the absence of bound peptides. The structural similarity to other LBPs can be exploited to accelerate drug repurposing.

The effect of boron in BxGa1−xN/SiC heteroepitaxy was established by X-ray diffraction reciprocal-space maps on symmetric 0002 and asymmetric 11 {overline 2} 4 reflections. The density of screw and edge threading dislocations was quantified in the framework of the mosaic model.

RAPID (RAtio method Pattern InDexing) is an ImageJ macro script developed for the quick determination of sample orientation and indexing of calibrated and uncalibrated zone axis aligned electron diffraction patterns from materials with a cubic crystal structure. In addition to SAED and NBED patterns, the program is also capable of handling zone axis TEM Kikuchi patterns and FFTs derived from HR(S)TEM images. The software enables users to rapidly determine whether materials are cubic, pseudo-cubic, or non-cubic, and to distinguish between P, I, and F Bravais lattices. It can also provide lattice parameters for material verification and aid in determining the camera constant of the instrument, thus making the program a convenient tool for on-site crystallographic analysis in the TEM laboratory.

BGaN epilayers with boron contents up to 5.6% were grown on SiC substrates by metal–organic chemical vapor deposition. The effects of boron incorporation on the structural and optical properties were studied by high-resolution X-ray diffraction (XRD), atomic force microscopy (AFM), Raman spectroscopy and photoluminescence (PL) spectroscopy. XRD reciprocal-space maps around the symmetric 0002 and asymmetric 11 {overline 2} 4 reflections allowed evaluation of the lattice constants and lattice mismatch with respect to the underlying substrate. XRD rocking curves and AFM measurements indicated the mosaic microstructure of the epilayer. The impact of boron content on crystallite size, tilt and twist is evaluated and the correlation with threading dislocation density is discussed. The deterioration of optical properties with increasing boron content was assessed by Raman and PL spectroscopy.

Third- and fourth-generation synchrotron light sources with high fluxes and beam energies enable the use of innovative X-ray translucent experimental apparatus. These experimental devices access geologically relevant conditions whilst enabling in situ characterization using the spatial and temporal resolutions accessible at imaging beamlines. Here, Heitt Mjölnir is introduced, a heated miniature triaxial rig based on the design of Mjölnir, but covering a wider temperature range and larger sample volume at similar pressure capacities. This device is designed to investigate coupled thermal, chemical, hydraulic and mechanical processes from grain to centimetre scales using cylindrical samples of 10 mm × 20 mm (diameter × length). Heitt Mjölnir can simultaneously reach confining (hydraulic) pressures of 30 MPa and 500 MPa of axial stress with independently controlled sample pore fluid pressure < 30 MPa. This internally heated apparatus operates to temperatures up to 573 K with a minimal vertical thermal gradient in the sample of <0.3 K mm−1. This new apparatus has been deployed in operando studies at the TOMCAT (Swiss Light Source), I12 JEEP (Diamond Light Source) and PSICHÉ (Synchrotron SOLEIL) beamlines for 4D X-ray microtomography with scan intervals of a few minutes. Heitt Mjölnir is portable and modular, allowing a wide range of 4D characterizations of low-grade metamorphism and deformational processes. It enables spatially and temporally resolved fluid–rock interaction studies at conditions of crustal reservoirs and is suitable for characterization of material properties in geothermal, carbonation or subsurface gas storage applications. Technical drawings and an operation guide are included in this publication.

Coherent X-ray imaging is an active field at synchrotron sources. The images rely on the available coherent flux over a limited field of view. At many synchrotron beamlines a double-crystal monochromator (DCM) is employed in a standard nondispersive arrangement. For coherent diffraction imaging it is advantageous to increase the available field of view by increasing the spatial coherence length (SCL) of a beam exiting such a DCM. Here, Talbot interferometry data together with ray-tracing simulations for a (+ − − +) four-reflection experimental arrangement are presented, wherein the first two reflections are in the DCM and the final fourth reflection is asymmetric at grazing exit. Analyses of the interferometry data combined with the simulations show that compared with the beam exiting the DCM a gain of 76% in the SCL was achieved, albeit with a factor of 20 reduction in flux density, which may not be a severe penalty at a synchrotron beamline. Previous efforts reported in the literature to increase the SCL that employed asymmetric crystal diffraction at grazing incidence are also discussed. A much reduced SCL is found presently in simulations wherein the same asymmetric crystal is set for grazing incidence instead of grazing exit. In addition, the present study is compared and contrasted with two other means of increasing the SCL. These are (i) focusing the beam onto an aperture to act as a secondary source, and (ii) allowing the beam to propagate in vacuum an additional distance along the beamline.

The differentially pumped rare-gas filter at the end of the VUV beamline of the Swiss Light Source has been adapted to house a windowless absorption cell for gases. Absorption spectra can be recorded from 7 eV to up to 21 eV photon energies routinely, as shown by a new water and nitrous oxide absorption spectrum. By and large, the spectra agree with previously published ones both in terms of resonance energies and absorption cross sections, but that of N2O exhibits a small shift in the { ilde{f D}} band and tentative fine structures that have not yet been fully described. This setup will facilitate the measurement of absorption spectra in the VUV above the absorption edge of LiF and MgF2 windows. It will also allow us to carry out condensed-phase measurements on thin liquid sheets and solid films. Further development options are discussed, including the recording of temperature-dependent absorption spectra, a stationary gas cell for calibration measurements, and the improvement of the photon energy resolution.

The structure of the title complex, [Zn2(C2H3O2)4(C11H9N3O)2], is triclinic containing half of the mol­ecule in the asymmetric unit. Each zinc atom is coordinated to a pyridyl and oxime nitro­gen from one di-2-pyridyl ketone oxime (dpko) ligand and a third nitro­gen from the other dpko pyridyl ring. Additionally, each zinc is coordinated to two acetato anions, one of which is bidentate and the other monodentate. The uncoordinated oxygen of the monodentate acetato group is involved in a hydrogen bond with the oxime hydrogen. The packing in the crystal is assisted by weak C—H⋯O inter­actions between acetato groups and neighboring pyridyl rings.

The structure of the title compound, [RuCl2(C7H10N2)2(C2H6OS)2], has monoclinic (P21/n) symmetry. The Ru—N distances of the coordination compound are influenced by the trans chloride or di­methyl­sulfoxide-κS ligands. The mol­ecular structure exhibits disorder for two of the terminal methyl groups of a dimethyl sulfoxide ligand.

The title SiIV complex, C16H21NO3Si, is built up by a tridentate dinegative Schiff base ligand bound to a sila­cyclo­hexane unit. The coordination geometry of the penta­coordinated SiIV atom is a distorted trigonal bipyramid. The presence of the sila­cyclo­hexane ring in the complex leads to an unusual coordination geometry of the SiIV atom with the N atom from the Schiff base ligand and an alkyl-C atom in apical positions of the trigonal bipyramid. There is a disorder of the methyl group at the imine bond with two orientations resolved for the H atoms [major orientation = 0.55 (3)]. In the crystal, C—H⋯O inter­actions are found within corrugated layers of mol­ecules parallel to the ab plane.

The title compound, (C2H10N2)2[(C10H12N2O8)(MoO3)2]·4H2O, which crystallizes in the monoclinic C2/c space group, was obtained by mixing molybdenum oxide, ethyl­enedi­amine and ethyl­enedi­amine­tetra­acetic acid (H4edta) in a 2:4:1 ratio. The complex anion contains two MoO3 units bridged by an edta4− anion. The midpoint of the central C—C bond of the edta4− anion is located on a crystallographic inversion centre. The independent Mo atom is tridentately coordin­ated by a nitro­gen atom and two carboxyl­ate groups of the edta4− ligand, together with the three oxo ligands, producing a distorted octa­hedral coordination environment. In the three-dimensional supra­molecular crystal structure, the dinuclear anions, the organo­ammonium counter-ions and the solvent water mol­ecules are linked by N—H⋯Ow, N—H⋯Oedta and O—H⋯O hydrogen bonds.

The title compound, C19H15BrN2O, crystallizes with two similar mol­ecules in the asymmetric unit. The extended structure features dimers linked by pairs of N—H⋯O and C—H⋯O hydrogen bonds. The HNCNO moiety of the title compound shows delocalization over the N—C—N part, as evidenced by the similar C—N bond distances.

The mol­ecular structure of the title compound, C20H26N2O2 reveals non-co-planarity between the central formamidine backbone and each of the outer meth­oxy- and i-propyl- substituted benzene rings with dihedral angles of 7.88 (15) and 81.17 (15)°, respectively, indicating significant twists in the mol­ecule. In the crystal, inter­molecular C—H⋯O inter­actions, forming an R34(30) graph set, occur within a two-dimensional layer that extends along the ac plane.

In the title solvate, C16H18N2O2·CH4O, the dihedral angles between the formamidine backbone and the pendant 2-meth­oxy­phenyl and 2,6-di­methyl­phenyl groups are 14.84 (11) and 81.61 (12)°, respectively. In the crystal, the components are linked by C—H⋯O, O—H⋯O and C—H⋯ π hydrogen bonds, generating a supra­molecular chain that extends along the crystallographic a-axis direction.

The highly cytotoxic macrocyclic trichothecene Isororidin A (C29H40O9) was isolated from the fungus Myrothesium verrucaria endophytic on the wild medicinal plant `Datura' (Datura stramonium L.) and was characterized by one- (1D) and two-dimensional (2D) NMR spectroscopy. The three-dimensional structure of Isororidin A has been confirmed by X-ray crystallography at 0.81 Å resolution from crystals grown in the ortho­rhom­bic space group P212121, with one mol­ecule per asymmetric unit. Isororidin A is the epimer of previously described (by X-ray crystallography) Roridin A at position C-13' of the macrocyclic ring.

The crystal structures of 16 boron sub­phthalo­cy­an­ines (BsubPcs) with structurally diverse axial groups were analyzed and com­pared to elucidate the impact of the axial group on the inter­molecular π–π inter­actions, axial-group inter­actions, axial bond length and BsubPc bowl depth. π–π inter­actions between the iso­indole units of adjacent BsubPc mol­ecules most often involve concave–concave packing, whereas axial-group inter­actions with adjacent BsubPc mol­ecules tend to favour the convex side of the BsubPc bowl. Furthermore, axial groups that contain O and/or F atoms tend to have significant hy­dro­gen-bonding inter­actions, while axial groups containing arene site(s) can participate in π–π inter­actions with the BsubPc bowl, both of which can strongly influence the crystal packing. Bulky axial groups did tend to disrupt the π–π inter­actions and/or axial-group inter­actions, preventing some of the close packing that is seen in BsubPcs with less bulky axial groups. The atomic radius of the heteroatom bonded to boron directly influences the axial bond length, whereas the axial group has minimal impact on the BsubPc bowl depth. Finally, the crystal growth method did not generally appear to have a significant impact on the solid-state arrangement, with the exception of water occasionally being incorporated into crystal structures when hygroscopic solvents were used. These insights can help with the design and fine-tuning of the solid-state structures of BsubPcs as they continue to be developed as functional materials in organic electronics.

Phenuiviridae nucleoprotein is the main structural and functional component of the viral cycle, protecting the viral RNA and mediating the essential replication/transcription processes. The nucleoprotein (N) binds the RNA using its globular core and polymerizes through the N-terminus, which is presented as a highly flexible arm, as demonstrated in this article. The nucleoprotein exists in an `open' or a `closed' conformation. In the case of the closed conformation the flexible N-terminal arm folds over the RNA-binding cleft, preventing RNA adsorption. In the open conformation the arm is extended in such a way that both RNA adsorption and N polymerization are possible. In this article, single-crystal X-ray diffraction and small-angle X-ray scattering were used to study the N protein of Toscana virus complexed with a single-chain camelid antibody (VHH) and it is shown that in the presence of the antibody the nucleoprotein is unable to achieve a functional assembly to form a ribonucleoprotein complex.

The application of grazing-incidence total X-ray scattering (GITXS) for pair distribution function (PDF) analysis using >50 keV X-rays from synchrotron light sources has created new opportunities for structural characterization of supported thin films with high resolution. Compared with grazing-incidence wide-angle X-ray scattering, which is only useful for highly ordered materials, GITXS/PDFs expand such analysis to largely disordered or nanostructured materials by examining the atomic pair correlations dependent on the direction relative to the surface of the supporting substrate. A characterization of nanocrystalline In2O3-derived thin films is presented here with in-plane-isotropic and out-of-plane-anisotropic orientational ordering of the atomic structure, each synthesized using different techniques. The atomic orientations of such films are known to vary based on the synthetic conditions. Here, an azimuthal orientational analysis of these films using GITXS with a single incident angle is shown to resolve the markedly different orientations of the atomic structures with respect to the planar support and the different degrees of long-range order, and hence, the terminal surface chemistries. It is anticipated that orientational analysis of GITXS/PDF data will offer opportunities to extend structural analyses of thin films by providing a means to qualitatively determine the major atomic orientation within nanocrystalline and, eventually, non-crystalline films.
