Abstract ∙ Knowledge of molt patterns and their resulting plumages is useful for aging and sexing birds and, in mono‐ chromatic species, morphometric measurements can help to discern males from females. However, these data are largely undescribed for the majority of the world’s bird species, especially in the tropics. We sought to classify the molt strategy for 10 species of Neotropical passerines during their breeding seasons and considered whether a combination of wing chord, tail length and mass could be used to determine their sex. We used banding data from three years of mark‐recapture study at Wayqecha Biological Station (2900 m a.s.l.) along the east slope of the Andes in southeastern Peru to characterize molt and estimate morphological measurements. Each of the species exhibited a complete definitive prebasic molt and either a partial (nine species) or partial‐incomplete (one species) preformative molt, which we interpreted to be consistent with a complex basic molt strategy. For five of the 10 species, we found that wing, tail, and body mass measurements were useful in distinguishing between males and females. This study contributes to our understanding of tropical bird molt by providing previously undescribed aging and sexing criteria for some tropical landbirds common to high elevations of southern Peru.Resumen ∙ Patrones de muda y criterios para categorizar sexo y edad en diez especies de aves altoandinas en el sureste de Perú Los patrones de muda en la mayoría de las aves Neotropicales son poco conocidos y en especial se desconoce si las medidas corporales pueden ser usadas para determinar el sexo en especies sin dimorfismo sexual. En este trabajo clasificamos la estrategia de muda para 10 especies de paserinos Neotropicales y también exploramos si una combi‐ nación de medidas de longitud del ala, longitud de la cola y masa corporal pueden ser usadas para la determinación del sexo. Usamos datos de anillamiento de tres años de un estudio de recaptura en la Estación Biológica Wayqecha (2900 m s.n.m.) en el flanco oriental de los Andes al sureste de Perú. Cada especie exhibió una estrategia básica compleja de muda con una muda prebásica definitiva compleja, y una muda preformativa parcial (nueve especies) o parcial‐incompleta (uno especie). Para cinco de cada 10 especies, la combinación de medidas de la longitud del ala, la cola, y la masa corporal sirvieron para distinguir entre machos y hembras. Este estudio contribuye a la creciente literatura sobre los patrones de muda en aves tropicales y provee herramientas para clasificar la edad y el sexo de aves con plumaje sexualmente monocromático.

Resumen ∙ El presente trabajo provee información sobre la dieta de subadultos de Pato Quetru no Volador (Tachyeres pteneres) en cuatro islas del sur de Chile durante los periodos estivales de los años 2007, 2009, 2012, 2013 y 2014. Se colectaron 293 fecas en cuatro islas del centro y sur de Chile: Isla Guamblin, isla Guapiquilán, isla Lacaos e isla Guafo. Se comparó el consumo de presas entre islas. Se identificaron 686 restos duros de invertebrados y vertebrados marinos y algas. Los cangrejos (Cancridae) se registraron como la presa más consumida en las cuatro islas. El número de categorías tróficas en las cuatro islas fluctuó entre 1 y 6 familias/feca. Al comparar el patrón de consumo de presas presentes en la dieta en las cuatro islas se observaron diferencias estadísticamente significativas en la composición de la dieta. Para las islas Lacaos y Guapiquilán las presas más consumidas correspondieron a cangrejos, mientras que para las islas Guafo y Guamblin las presas más consumidas fueron los moluscos (Mollusca). Abstract ∙ Diet of the Magellanic Flightless Steamer-Duck (Tachyeres pteneres) in islands of southern Chile We provide information on the diet of the Magellanic Flightless Steamer-Duck (Tachyeres pteneres) in four continental islands of southern Chile during the Austral summer periods of the years 2007, 2009, 2012, 2013, and 2014. A total of 293 feces were collected in Guamblin island, Guapiquilán island, Lacaos island and Guafo island. Based on these we identified 686 hard remains of invertebrates, marine vertebrates, and algae. Crabs (Cancridae) were the most common prey consumed across the four islands. The number of trophic categories fluctuated between 1 to 6 families/feces across the four islands. We found statistically significant differences in diet composition between the four islands. In Lacaos and Guapiquilán islands, the most consumed prey corresponded to crabs, while in Guafo and Guamblin islands the most consumed prey were mollusks (Mollusca).

Published: February 2023

While motmots (Momotidae) are known to feed on mammals, this information comes mainly from the analysis of stomach con- tents. On 2 November 2018, our camera trap, located in the Projeto Dacnis area in São Francisco Xavier, a district of the municipality of São José dos Campos, State of São Paulo, Brazil, recorded a Rufous-capped Motmot (Baryphthengus ruficapillus) on a perch with a small opossum (Monodelphis sp.) in its bill. Since the bird repeatedly hit the mammal ́s head against the perch, we assumed it was a predation event. This is the first video record of a B. ruficapillus preying on a mammal, as well as the first record of a motmot preying on a marsupial. Videos record- ed by camera traps are a valuable source of natural history data, as they provide records not only about dietary items, but also about the associated predatory behavior.

Abstract. Unprecedented cavity nesting among falconids: a Chimango Caracaras (Milvago chimango) population using Borruwing Parrots (Cyanoliseus patagonus) nests in Patagonia Argentina. The Chimango Caracara (Milvago chimango) is the most abundant member of raptor assemblages from Paraguay and Bolivia to the southern tip of Argentina. In Argentinian Patagonia we studied nesting and other biological aspects of a Chimango Caracaras population that exploits cavities built by marine psittacines, in a unique ornithological assemblage: 12 km of sea cliffs with 37,000 active nests of Burrowing Parrots (Cyanoliseus patagonus). During 56 days we assessed a total of 18 active Chimango Caracaras nests (11 in 2014 and 7 in 2015). All nests contained plant material inside and had some structure to facilitate landing and perching. Most were located in the upper third of the cliff and had a single entrance mouth. The average distance to the nearest nest in the same breeding season was 108.9 m ± SD 90.90 m. We document in detail for the first time the construction of Chimango Caracaras nests inside cavities. Our results document a new breeding substrate for this species and a nesting behaviour unique among falconids, which could be interpreted as evidence of adaptability and plasticity of Chimango Caracaras.
Robust Testing for Bollinger Band, Moving Average and Relative Strength Index
Authors: Lutey Matthew 
Published: February 2023

We test whether the moving average indicator is profitable in trend following and compare the result with common momentum indicators such as Relative Strength Index (RSI) and Bollinger Band (BB). Our sample runs from January 1, 1963, through December 31. 2019. We test whether the signals generated are profitable and compare their success in timing the portfolios based on the previous year's volatility using the Center for Research in Security Prices (CRSP) data. We note the portfolios sorted by volatility to be trend following and use common entry points for timing them. We find all indicators to be more profitable than the Buy and Hold (BH). The moving average (MA) has the strongest return, while BB and RSI show positive return they do worse than the MA. The results hold across all portfolio deciles sorted by both size and volatility. The indicators for RSI and BB are robust to other specifications for entry and parameters. We also show price level analysis for both RSI and BB as well as a trailing three year analysis for the volatility deciles and moving average.

Background: Cerebral palsy is a group of non-progressive disorders of movement or posture. Visual handicap in Cerebral Palsy patients can have a direct impact on psychosocial status. Refractive errors, strabismus, nystagmus, amblyopia and cortical visual impairment are observed in 50 to 90 % of patients with cerebral palsy.
Objective: To evaluate for visual impairment in CP patients at Children’s Hospital at UTHs.
Methods: A cross section study was performed on 100 Cerebral palsy patients attending the neurological clinic at the University Teaching Hospitals-Children’s Hospital from February to April 2021. The patients were sampled systematically from the register at neurology clinic and ophthalmological examination was conducted at Eye hospital which included measurement of visual acuity, ocular motility, refraction along with the evaluation of the anterior and posterior segments.
Results: Fourty nine percent (49%) of the patients seen had ocular abnormalities of which the most common abnormality was refractive error (32.5%) followed by strabismus (21.5%). Esodeviation was more commonly found than exodeviation (65.0% vs 35.0%), and hyperopia was slightly more prevalent than myopia. Astigmatism was the most common refractive error at 40.0%.
Conclusions: Children with cerebral palsy at the University Teaching Hospitals-Children’s Hospital have a high prevalence of strabismus and refractive errors. Esotropia and hyperopia are the most common ocular abnormalities. All children with cerebral palsy may require a detailed ophthalmologic evaluation.

ImportanceUntil now, other than complex neurologic tests, there have been no readily accessible and reliable indicators of neurologic dysfunction among patients with Parkinson disease (PD). This study was conducted to determine the role of fundus photography as a noninvasive and readily available tool for assessing neurologic dysfunction among patients with PD using deep learning methods.ObjectiveTo develop an algorithm that can predict Hoehn and Yahr (H-Y) scale and Unified Parkinson’s Disease Rating Scale part III (UPDRS-III) score using fundus photography among patients with PD.Design, Settings, and ParticipantsThis was a prospective decision analytical model conducted at a single tertiary-care hospital. The fundus photographs of participants with PD and participants with non-PD atypical motor abnormalities who visited the neurology department of Kangbuk Samsung Hospital from October 7, 2020, to April 30, 2021, were analyzed in this study. A convolutional neural network was developed to predict both the H-Y scale and UPDRS-III score based on fundus photography findings and participants’ demographic characteristics.Main Outcomes and MeasuresThe area under the receiver operating characteristic curve (AUROC) was calculated for sensitivity and specificity analyses for both the internal and external validation data sets.ResultsA total of 615 participants were included in the study: 266 had PD (43.3%; mean [SD] age, 70.8 [8.3] years; 134 male individuals [50.4%]), and 349 had non-PD atypical motor abnormalities (56.7%; mean [SD] age, 70.7 [7.9] years; 236 female individuals [67.6%]). For the internal validation data set, the sensitivity was 83.23% (95% CI, 82.07%-84.38%) and 82.61% (95% CI, 81.38%-83.83%) for the H-Y scale and UPDRS-III score, respectively. The specificity was 66.81% (95% CI, 64.97%-68.65%) and 65.75% (95% CI, 62.56%-68.94%) for the H-Y scale and UPDRS-III score, respectively. For the external validation data set, the sensitivity and specificity were 70.73% (95% CI, 66.30%-75.16%) and 66.66% (95% CI, 50.76%-82.25%), respectively. Lastly, the calculated AUROC and accuracy were 0.67 (95% CI, 0.55-0.79) and 70.45% (95% CI, 66.85%-74.04%), respectively.Conclusions and RelevanceThis decision analytical model reveals amalgamative insights into the neurologic dysfunction among PD patients by providing information on how to apply a deep learning method to evaluate the association between the retina and brain. Study data may help clarify recent research findings regarding dopamine pathologic cascades between the retina and brain among patients with PD; however, further research is needed to expand the clinical implication of this algorithm.

ObjectiveRacial and ethnic disparities in rheumatoid arthritis (RA) disease activity measures have been documented. We compared racial and ethnic differences in disease activity using multiple composite measures, including an objective measure, the multi‐biochemical disease activity (MBDA) score.MethodsData are derived from the University of California, San Francisco RA Cohort, a longitudinal observational cohort. Participants with at least one MBDA measure and self‐reported race and ethnicity were included. Multivariable linear regression evaluated the association between race and ethnicity groups and mean MBDA score, adjusting for potential confounders, including symptom duration and medication use. Sensitivity analyses substituted the Clinical Disease Activity Index (CDAI) and the Disease Activity Score‐28 joints with erythrocyte sedimentation rate (DAS28‐ESR) for the MBDA in multivariable models.ResultsWe included 267 participants (86% female, mean age 52.7 ± 13.3 years). The majority were Latinx (n = 137; 51%), followed by Asian (n = 91; 34%). After adjustment, Latinx participants had the highest mean MBDA score (40.6 ± 2.1) compared with White participants at (32.8 ± 6.7). Black participants had the second highest mean MBDA score, followed by Asian participants (36.3 ± 5.3, 36.0 ± 2.7, respectively), although neither were significantly different from White participants. The trends observed for the CDAI and DAS28‐ESR were similar to those for the MBDA.ConclusionWe found significantly higher disease activity measured by the MBDA and DAS28‐ESR in Latinx participants compared with White participants. We also found significantly higher disease activity in Asian participants compared with White participants with the DAS28‐ESR. Our findings, although limited by the small number of White participants in the referent group, suggest that RA disease activity measures may be influenced by external factors that have differential impacts by racial and ethnic group.

AbstractThe growing usage and consumption of electronics‐integrated items into the daily routine has raised concerns on the disposal and proper recycling of these components. Here, a fully sustainable and green technology for the fabrication of different electronics on fruit‐waste derived paper substrate, is reported. The process relies on the carbonization of the topmost surface of different cellulose‐based substrates, derived from apple‐, kiwi‐, and grape‐based processes, by a CO2 laser. By optimizing the lasing parameters, electronic devices, such as capacitors, biosensors, and electrodes for food monitoring as well as heart and respiration activity analysis, are realized. Biocompatibility tests on fruit‐based cellulose reveal no shortcoming for on‐skin applications. The employment of such natural and plastic‐free substrate allows twofold strategies for electronics recycling. As a first approach, device dissolution is achieved at room temperature within 40 days, revealing transient behavior in natural solution and leaving no harmful residuals. Alternatively, the cellulose‐based electronics is reintroduced in nature, as possible support for plant seeding and growth or even soil amendment. These results demonstrate the realization of green, low‐cost and circular electronics, with possible applications in smart agriculture and the Internet‐of‐Thing, with no waste creation and zero or even positive impact on the ecosystem.

Published: February 2023

AbstractI‐III‐VI2 semiconductor nanocrystals have been explored in countless optoelectronics and green energy applications. While indium‐based compounds are arguably the best‐known variants of these semiconductors and have been widely studied for their photophysical properties, other I‐III‐VI2 semiconductors are emerging as serious competitors. This review focuses on the current state of the art and recent progress made in the research and technology of one of the most promising competitors to indium‐based I‐III‐VI2 semiconductor nanocrystals, CuFeS2 nanocrystals. CuFeS2 is a promising alternative to indium‐based systems, mostly because many properties are competitive and because iron is much more abundant than indium. Replacing In(III) with Fe(III) would thus significantly alleviate the issue of raw material availability. The article highlights new synthesis approaches and summarizes and discusses advanced optical properties including surface plasmon resonance and luminescence properties. Moreover, potential applications in thermoelectric, photodetection, photothermal, and photovoltaics are illustrated and discussed. Finally, future perspectives for materials development, upscaling, and application in new processes and devices, such as self‐assembly, patterning, or plasmonic catalysis, are presented as well.

AbstractChiral hybrid organic−inorganic perovskites (HOIPs) with intrinsic noncentrosymmetry have shown great potentials for chiroptoelectronic applications including second‐order nonlinear optics (NLO). Ideal NLO materials should simultaneously feature a large NLO coefficient, wide optical transparency, high laser damage threshold, and physicochemical stability. However, the development of applicable second‐order NLO materials has been largely restricted due to their strict requirement on structural noncentrosymmetry. Here, chiral amino acids abundant in nature have been adopted to synthesize hybrid lead halide perovskites (D‐/L‐Pro)PbI3·H2O (Pro = Proline) with resonance enhanced second‐harmonic generation (SHG). Their crystals feature balanced NLO performances with a large NLO coefficient, wide transparent region, high laser damage threshold, and high polarization ratio. This work demonstrates the promise of naturally abundant amino acids for the construction of hybrid chiral metal halide perovskites for next generation optoelectronic materials.

Published: February 2023

AbstractSemitransparent organic photovoltaics (ST‐OPVs) have great application potential in photovoltaic buildings and wearable devices. Studies have proved that power conversion efficiency (PCE) and average visible transmittance (AVT) reveal more balanced in pseudoplanar heterojunction (PPHJ) structure than in bulk heterojunction (BHJ) structure. An interesting approach named low temperature sequential deposition (LTSD)—spin‐coating the small molecule acceptor (A) Y6 on polymer donor (D) PM6—is proposed to form an efficient PPHJ structure. In the LTSD process, small molecule Y6 will diffuse through amorphous PM6 layer which means that Y6 finally aggregates at the bottom of active layer and results in vertical gradient concentration distribution. In this structure, adjustment of D:A ratio can achieve higher AVT with maintaining less PCE loss compared with BHJ structure. The fabricated LTSD devices provide PCE of 12.36% (AVT of 23.19%) at 45:40 nm (D:A layer thickness) and PCE of 11.26% (AVT of 25.10%) at 40:40 nm (D:A), while BHJ devices provide PCE of 11.43% (AVT of 21.32%) at 85 nm (D:A = 1:1.2 w). Besides, the LTSD devices are more stable than BHJ devices due to smoother surface. LTSD strategy provides a new approach for achieving PPHJ structure and high‐performance ST‐OPVs.
