Debunking the Myth of Nicaraguan Exceptionalism: Crime, Drugs and the Political Economy of Violence in a ‘Narco-state’
Authors: Rocha José Luis , Rodgers Dennis , Weegels Julienne 
Published: September 2023

AbstractNicaragua is often held up as an exception within the Central American panorama of criminal violence, widely presented as the safest country in the region due to its particular revolutionary legacies, the (supposed) absence of transnational gangs and drug-trafficking organisations, and the National Police's representation as an efficient and professional force. This commentary proposes an alternative reading of Nicaragua's contemporary political economy of violence in order to reveal the profoundly misleading nature of this prevalent view. In particular, it highlights how Nicaragua is governed through a particular political ‘settlement’ underpinned by drug trafficking, police and judicial corruption, as well as ‘mafia state’ governance. These factors have coalesced to establish a highly efficient and engrained ‘narco-state’ whose undoing is unlikely in the short term.

Abstract
The spatial and seasonal variability of the microphytoplankton and ciliates communities in relation to the environmental factors were studied in the southern coastal area of Sfax. Results revealed a striking difference between seasons regarding pH, with strong acidification in autumn generated by industrial activity. Spatial distribution of pH in autumn impacted the microorganisms in different ways: acidic stations to the south showed significant correlations with Cyanobacteria, dinoflagellates and loricate ciliates whereas higher pH values in spring (pH > 8) were linked to diatoms richness. The high availability of inorganic phosphate is associated with the high release of phosphate due to residue from a phosphate treatment manufacture along the coast; consequently, N/P ratios were low (1.34–13.43) suggesting nitrogen limitation. Microphytoplankton abundance shifted from dinoflagellates dominance in autumn to dominance of diatoms during winter and of Euglenophyceae in summer. Loricate ciliates accounted for the largest proportion of the ciliates community while aloricate ciliates were relatively scarce during all seasons. Variability of ciliate community appeared not directly linked to environmental conditions, but significant positive relationships between abundance of loricate ciliates and microphytoplankton suggest that these ciliates may feed on microphytoplankton.
Exploring the diversity of the deep-sea shrimp in the ‘Glyphocrangon spinicauda A. Milne-Edwards, 1881’ species group (Decapoda, Crustacea, Glyphocrangonidae) off Taiwan and Dongsha

Abstract
Examination of the material collected by Taiwan deep-sea cruises reveals the presence of five species of the deep-sea shrimp genus Glyphocrangon A. Milne-Edwards, 1881, representing new records for Taiwan and Dongsha (Pratas Island; under jurisdiction of Taiwan). These species are Glyphocrangon albatrossae, G. caecescens, G. indonesiensis, G. major and G. proxima, all of which belong to the informal Glyphocrangon spinicauda species group. These findings bring the total number of species in the G. spinicauda species group reported in the waters around Taiwan and Dongsha to 11. The complex ornamentation of the body surface of each species is shown using micro-computed tomography. Diagnosis and illustrations showing diagnostic characters and living colouration are provided for most, if not all, of these species. Glyphocrangon grandis is placed under the synonymy of G. major based on morphology, because it was found that diagnostic characters proposed to distinguish these two taxa are variable within the current series of specimens. The biogeographical distributions of these species are presented, and a key is provided to help identify the 11 known species in this region.
Speaking for Others from the Bench
Authors: Salkin Wendy 
Published: September 2023

AbstractIn this article, I introduce and examine the novel concept of bench representation. Jurists and scholars have extensively examined whether judges are or ought to be considered symbolic representatives of abstract concepts (for instance, the law, equality, or justice), representatives of society as a whole, or descriptive representatives of the social groups from which they hail. However, little attention has been paid to the question whether judges act as representatives for the parties before them through their everyday work on the bench. This article examines that question. Bench representation occurs when a judge, through statements or actions undertaken during the performance of official duties, speaks or acts for a party to the proceeding before them. I argue that serving as a bench representative is a common and valuable feature of what it is to be a judge and, despite appearances, usually undermines neither impartiality nor fairness.

Published: September 2023

AbstractFreezing damage is a major limiting factor to Pistachio cultivation in cold climates. Assessment of pistachio genotypes to freezing stress is important for the selection of tolerance cultivars in these regions. In this study, nine genotypes belong to six Pistacia species (P. terebinthus L., P. atlantica Desf., P. atlantica subsp. kurdica P. atlantica subsp. mutica, P. khinjuk Stocks., P. vera var. Sarakhs, P. vera cv. Badami-Riz-Zarand I, P. vera cv. Badami-Riz-Zarand II) and an interspecies hybrid named UCB1 (P. atlantica × P. integrrima) were evaluated to freezing stress at temperatures of −4, −8, −12 and, −16°C in the months of December, January and February. Results showed that electrolyte leakage (EL) percentage and means of eco-physiological parameters varied among genotypes with the highest soluble carbohydrates and phenolic compounds observed in species of P. atlantica subsp. kurdica and P. vera var. Sarakhs respectively. In February, the highest calcium and potassium concentrations of shoot were observed in P. terebinths and P. vera var. Sarakhs genotypes respectively. The highest EL percentage was observed at −16°C in P. atlantica and P. khinjuk and the lowest in P. terebinthus and P. vera var. Sarakhs.
Evading National Identity: On Translocal Irish Folk Music in Austria
Authors: MORGENSTERN FELIX 
Published: September 2023

AbstractThis article assesses how translocal Irish folk-music practices and their consumption in Austria elide the traumatic legacy of extreme nationalism in modern European history. Furthermore, it teases out the degree to which the affinity of Austrian performers and audiences with Irish folk music might provide an alternative sphere of cultural identification to indigenous Austrian folk-music practices. Combining ethnographic and historical inquiry, the article unravels how various nostalgically sustained imaginaries of Irishness find complex refractions in the Austrian present, while also interrogating the stakes of an emerging insistence upon the primacy of “the music itself” in ethnographic voices.

Published: September 2023

AbstractEquatorial plasma bubble (EPB) development during different phases of the geomagnetic storm of 3–4 November 2021 (SYMHmin = −118 nT) was examined using observations and simulations. The initial phase of the storm coincided with postsunset (about 30 min after sunset) at Fortaleza (FZ) and São Luís (SL) with longitudes of ∼38.45°W and ∼44°W respectively on November 3 while the recovery phase of the storm started at 12:45 UT on November 4. GOLD shows the longest (shortest) extension of EPBs on November 3 (4) compared to days before and after November 3 and 4, including quiet days. This indicates an intensification (weakening) of EPBs on November 3 (4). From ionosondes at FZ and SL, a strong (weak) range spread F (SSF (RSF)) was observed on November 3 (4). The postsunset peak F layer height on November 3 reached 450 km and exceeded the preceding and succeeding days by ∼50–100 km at SL indicating the presence of a Prompt Penetration Electric Field (PPEF) which enhanced EPB development via the favorable postsunset vertical E x B and Rayleigh‐Taylor instability (RTI) mechanisms on November 3. The lower‐than‐quiet time F layer height observed on November 4 during Pre‐reversal enhancement (PRE) indicates the presence of a westward‐oriented Disturbance Dynamo Electric Field (DDEF) that undermined RTI growth and led to the weakening of EPB development. Simulation results confirm that the storm‐time electric fields modified the evening‐time ionosphere and influenced the magnitude of vertical E x B drift required for the development of EPBs.

Published: September 2023

AbstractEvery planet or moon with an ionosphere is thought to generate a weak electrical potential which helps ions overcome gravity and escape to space. A pilot study at Venus by Collinson et al. (2016, https://doi.org/10.1002/2016GL068327) indicated a planetary potential an order of magnitude stronger than expected. Here we present a statistical study of the electrical potential drop in the ionosphere of Venus, which was found to be an average of 7.04 ± 2.19 V. However, these strong potentials measured by Venus Express are likely atypical and extreme outliers associated with a transient phenomenon in the Venusian ionosphere. We posit they are associated with transient and sporadic density cavities in the ionosphere and may be the result of sporadic electrostatic double layer formation in the dayside ionosphere.
Maxillary sinus floor augmentation: a review of current evidence on anatomical factors and a decision tree
Authors: Lyu Mingyue , Xu Dingyi , Zhang Xiaohan , Yuan Quan 
Published: September 2023

AbstractMaxillary sinus floor augmentation using lateral window and crestal technique is considered as predictable methods to increase the residual bone height; however, this surgery is commonly complicated by Schneiderian membrane perforation, which is closely related to anatomical factors. This article aimed to assess anatomical factors on successful augmentation procedures. After review of the current evidence on sinus augmentation techniques, anatomical factors related to the stretching potential of Schneiderian membrane were assessed and a decision tree for the rational choice of surgical approaches was proposed. Schneiderian membrane perforation might occur when local tension exceeds its stretching potential, which is closely related to anatomical variations of the maxillary sinus. Choice of a surgical approach and clinical outcomes are influenced by the stretching potential of Schneiderian membrane. In addition to the residual bone height, clinicians should also consider the stretching potential affected by the membrane health condition, the contours of the maxillary sinus, and the presence of antral septa when evaluating the choice of surgical approaches and clinical outcomes.
Novel neurosteroid therapeutics for post-partum depression: perspectives on clinical trials, program development, active research, and future directions

Published: September 2023

AbstractThis article reviews novel neurosteroid therapeutics for post-partum depression, with a focus on their development, clinical trial data, current practices, and future directions in this exciting field. We discuss the clinical impact of brexanolone and several other neurosteroids, particularly as they relate to the treatment of postpartum depression (PPD) and major depressive disorders outside of the perinatal period. There has been increasing interest in GABA signaling and modulation as it pertains to the development of altered circuity and depressive states. This scientific underpinning served as the rationale for the initial development of brexanolone. We review the clinical trials supporting its Food and Drug Administration (FDA) approval as the first rapidly acting antidepressant specific for PPD, and the subsequent development of a clinical brexanolone program at an academic medical center, highlighting new research and data from that site as well as the challenges with the delivery of this I.V. drug. In addition to the GABA signaling hypothesis, we discuss the new evidence demonstrating that brexanolone inhibits inflammatory signaling post-infusion, suggesting that inflammatory signaling may contribute to the etiology of PPD. Finally, we describe new and future directions in neurosteroid therapeutics, including the development of an oral agent, zuranolone, and the IV and oral formulations of ganaxolone. Ultimately, the hope is that these novel neurosteroid therapeutics will provide fast-acting treatment for these impairing disorders and improve our understanding of the underlying mechanisms of depressive disorders.

AbstractGranular biofilms producing medium-chain carboxylic acids (MCCA) from carbohydrate-rich industrial feedstocks harbor highly streamlined communities converting sugars to MCCA either directly or via lactic acid as intermediate. We investigated the spatial organization and growth activity patterns of MCCA producing granular biofilms grown on an industrial side stream to test (i) whether key functional guilds (lactic acid producing Olsenella and MCCA producing Oscillospiraceae) stratified in the biofilm based on substrate usage, and (ii) whether spatial patterns of growth activity shaped the unique, lenticular morphology of these biofilms. First, three novel isolates (one Olsenella and two Oscillospiraceae species) representing over half of the granular biofilm community were obtained and used to develop FISH probes, revealing that key functional guilds were not stratified. Instead, the outer 150–500 µm of the granular biofilm consisted of a well-mixed community of Olsenella and Oscillospiraceae, while deeper layers were made up of other bacteria with lower activities. Second, nanoSIMS analysis of 15N incorporation in biofilms grown in normal and lactic acid amended conditions suggested Oscillospiraceae switched from sugars to lactic acid as substrate. This suggests competitive-cooperative interactions may govern the spatial organization of these biofilms, and suggests that optimizing biofilm size may be a suitable process engineering strategy. Third, growth activities were similar in the polar and equatorial biofilm peripheries, leaving the mechanism behind the lenticular biofilm morphology unexplained. Physical processes (e.g., shear hydrodynamics, biofilm life cycles) may have contributed to lenticular biofilm development. Together, this study develops an ecological framework of MCCA-producing granular biofilms that informs bioprocess development.

Published: September 2023

AbstractMultisensory integration is a salient feature of the brain which enables better and faster responses in comparison to unisensory integration, especially when the unisensory cues are weak. Specialized neurons that receive convergent input from two or more sensory modalities are responsible for such multisensory integration. Solid-state devices that can emulate the response of these multisensory neurons can advance neuromorphic computing and bridge the gap between artificial and natural intelligence. Here, we introduce an artificial visuotactile neuron based on the integration of a photosensitive monolayer MoS2 memtransistor and a triboelectric tactile sensor which minutely captures the three essential features of multisensory integration, namely, super-additive response, inverse effectiveness effect, and temporal congruency. We have also realized a circuit which can encode visuotactile information into digital spiking events, with probability of spiking determined by the strength of the visual and tactile cues. We believe that our comprehensive demonstration of bio-inspired and multisensory visuotactile neuron and spike encoding circuitry will advance the field of neuromorphic computing, which has thus far primarily focused on unisensory intelligence and information processing.

AbstractA repeat expansion in the C9orf72 (C9) gene is the most common genetic cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Here we investigate single nucleus transcriptomics (snRNA-seq) and epigenomics (snATAC-seq) in postmortem motor and frontal cortices from C9-ALS, C9-FTD, and control donors. C9-ALS donors present pervasive alterations of gene expression with concordant changes in chromatin accessibility and histone modifications. The greatest alterations occur in upper and deep layer excitatory neurons, as well as in astrocytes. In neurons, the changes imply an increase in proteostasis, metabolism, and protein expression pathways, alongside a decrease in neuronal function. In astrocytes, the alterations suggest activation and structural remodeling. Conversely, C9-FTD donors have fewer high-quality neuronal nuclei in the frontal cortex and numerous gene expression changes in glial cells. These findings highlight a context-dependent molecular disruption in C9-ALS and C9-FTD, indicating unique effects across cell types, brain regions, and diseases.

AbstractMolybdenum supported on zeolites has been extensively studied as a catalyst for methane dehydroaromatization. Despite significant progress, the actual intermediates and particularly the first C-C bond formation have not yet been elucidated. Herein we report evolution of methyl radicals during non-oxidative methane activation over molybdenum single sites, which leads selectively to value-added chemicals. Operando X-ray absorption spectroscopy and online synchrotron vacuum ultraviolet photoionization mass spectroscopy in combination with electron microscopy and density functional theory calculations reveal the essential role of molybdenum single sites in the generation of methyl radicals and that the formation rate of methyl radicals is linearly correlated with the number of molybdenum single sites. Methyl radicals transform to ethane in the gas phase, which readily dehydrogenates to ethylene in the absence of zeolites. This is essentially similar to the reaction pathway over the previously reported SiO2 lattice-confined single site iron catalyst. However, the availability of a zeolite, either in a physical mixture or as a support, directs the subsequent reaction pathway towards aromatization within the zeolite confined pores, resulting in benzene as the dominant hydrocarbon product. The findings reveal that methyl radical chemistry could be a general feature for metal single site catalysis regardless of the support (either zeolites MCM-22 and ZSM-5 or SiO2) whereas the reaction over aggregated molybdenum carbide nanoparticles likely facilitates carbon deposition through surface C-C coupling. These findings allow furthering the fundamental insights into non-oxidative methane conversion to value-added chemicals.

AbstractLocal deformation of atomically thin van der Waals materials provides a powerful approach to create site-controlled chip-compatible single-photon emitters (SPEs). However, the microscopic mechanisms underlying the formation of such strain-induced SPEs are still not fully clear, which hinders further efforts in their deterministic integration with nanophotonic structures for developing practical on-chip sources of quantum light. Here we investigate SPEs with single-photon purity up to 98% created in monolayer WSe2 via nanoindentation. Using photoluminescence imaging in combination with atomic force microscopy, we locate single-photon emitting sites on a deep sub-wavelength spatial scale and reconstruct the details of the surrounding local strain potential. The obtained results suggest that the origin of the observed single-photon emission is likely related to strain-induced spectral shift of dark excitonic states and their hybridization with localized states of individual defects.

AbstractAnti-Stokes photoluminescence (PL) is light emission at a higher photon energy than the excitation, with applications in optical cooling, bioimaging, lasing, and quantum optics. Here, we show how plasmonic nano-cavities activate anti-Stokes PL in WSe2 monolayers through resonant excitation of a dark exciton at room temperature. The optical near-fields of the plasmonic cavities excite the out-of-plane transition dipole of the dark exciton, leading to light emission from the bright exciton at higher energy. Through statistical measurements on hundreds of plasmonic cavities, we show that coupling to the dark exciton leads to a near hundred-fold enhancement of the upconverted PL intensity. This is further corroborated by experiments in which the laser excitation wavelength is tuned across the dark exciton. We show that a precise nanoparticle geometry is key for a consistent enhancement, with decahedral nanoparticle shapes providing an efficient PL upconversion. Finally, we demonstrate a selective and reversible switching of the upconverted PL via electrochemical gating. Our work introduces the dark exciton as an excitation channel for anti-Stokes PL in WSe2 and paves the way for large-area substrates providing nanoscale optical cooling, anti-Stokes lasing, and radiative engineering of excitons.
