Dawn chorus interpretation differs when using songs or calls: the Dupont’s Lark Chersophilus duponti case
Authors: Pérez-Granados Cristian , Osiejuk Tomasz S. , López-Iborra Germán M. 
Published: July 2018

Background
Territorial songbirds vocalise intensively before sunrise and then decrease their vocal activity. This creates a communication network that disseminates essential information for both males and females. The function of dawn chorus in birds has been frequently interpreted according to seasonal variation of singing as the breeding season advances, but potential differences in seasonal variation of song and calls for the same species have not been taken into account.

Methods
We chose Dupont’s Lark as a model species to study whether the seasonal pattern of dawn chorus differs between singing and calling activity, because in this species most daily songs and calls are uttered at dawn. We registered vocal activity of Dupont’s Lark before and around dawn in three different populations, through repeated sampling over the entire breeding season of two consecutive years.

Results
We found that dawn singing parameters remained constant or presented an increasing trend while dawn calling activity decreased as breeding season advanced. We also found different daily patterns for singing and calling, with birds calling mostly during the first 30 minutes of dawn choruses and singing peaking afterwards.

Discussion
The different time patterns of songs and calls may indicate that they serve diverse functions at dawn in the Dupont’s Lark. Relaxation of dawn calling activity after the first month of the breeding season would suggest that dawn calling may be mainly related to mate attraction, while constant dawn singing throughout the breeding period would support a relationship of dawn singing to territorial defence. Our study highlights that the type of vocalisation used is an important factor to consider in further research on dawn choruses, since results may differ depending on whether calls or songs are analysed.
Theories of Arousal Predict a Link Between Heart Rate Variability and Reactive Aggression: Meta‐Analytic Results Disagree
Authors: McCurry Annah G. , May Robert C. , Donaldson David I. 
Published: November 2024

ABSTRACTPolyvagal theory posits that habitually aggressive individuals might have an impaired capacity to calm after arousal, which has led to the investigation of Arousal‐based biological indicators ‐ “biomarkers” ‐ of aggression, to identify individuals at high risk. The most popular approach in research examining (specifically reactive) aggression is the use of wearable technologies that can non‐invasively measure heart rate variability (HRV), a cardiovascular phenomenon impacted by activation of the parasympathetic (“rest and digest”) nervous system. But there is a problem: no one has systematically analyzed the results of these studies to determine if HRV is an effective predictor of reactive aggression. We surveyed an initial 705 articles, producing 48 effect estimates amenable to meta‐analysis. Counter to predictions derived from polyvagal theory, the results reveal no correlation between HRV and reactive aggression. We discuss the implications of this novel finding for theory and practice, considering both the complexity of identifying effective biomarkers and the practical limitations driving methodological decisions in aggression research. We conclude that there is no empirical evidence supporting HRV as a valid biomarker of aggression.

AbstractIn addressing the critical limitations associated with platelet storage, the study investigates an innovative solution aimed at preventing the unwanted activation of platelets within storage bags. This activation is a key factor that currently restricts the shelf life of platelet products to only 72 h, leading to extreme waste production and high costs. Here, highly effective surfaces are identified for minimizing surface‐induced platelet activation. Using thermal nanoimprint lithography (T‐NIL), a new method is demonstrated for patterning reproducible agarose micro/nanostructures (a natural hydrogel with anti‐platelet adhesive properties) including dots, chains, pills, and squares. The agarose (3%) structured surfaces displayed outstanding flexibility and hydrophilic behavior that prevented platelet adhesion as confirmed by confocal microscopy. Importantly, pill‐shaped structures effectively maintained their ability to prevent platelet adhesion, even after a long cell‐contacting duration. Atomic force microscopy indicated that the effectiveness of dampening platelet adherence is determined by the shape, size, height, and aspect ratio of the structures. A model is provided to explain how the different shapes affect wettability and thereby hinder platelet adherence. The developed anti‐adhesive agarose structured surfaces show promise to revolutionize platelet storage, provide vital insights into biomaterials research, and demonstrate the potential of tailored agarose surfaces in biomedical applications.

AbstractThermally conductive polymer composites hold great potential for thermal management applications in the electronics industry, but achieving metal‐like thermal conductivity (>200 W m−1 K−1) remains challenging due to the inevitable phonon scattering and the thermal resistance at filler‐filler and filler‐matrix interfaces. Herein, an efficient approach is presented to overcome this long‐standing barrier by designing a densified interconnecting filler framework, featuring a macro‐level carbon fiber (CF) array welded with a high‐quality, self‐assembled graphene network. In this framework, vertically aligned continuous CFs function as primary through‐plane thermal conduction paths, minimizing phonon scattering and thermal resistance. Meanwhile, the secondary graphene network interconnects the CFs into a more integrated and densified framework while introducing supplementary thermal conduction paths. Following polymer backfilling, the resulting epoxy nanocomposite exhibits an unprecedented through‐plane thermal conductivity of 262 W m−1 K−1 at a filler loading of 23.3 vol%, establishing a new benchmark among the thermally conducting polymer composites. When employed as a thermal interface material, this composite offers a 68.2% enhancement in cooling efficiency compared to standard commercial counterparts. Furthermore, the functional composite presents excellent Joule heating and interfacial adhesion properties, making it promising for thermal interface healing and multifunctional thermal management applications in complex environments.

Published: November 2024

AbstractQuasi‐2D perovskites are widely used in solar cells, photodetectors, and light‐emitting diodes (LEDs) due to their excellent optoelectronic properties and stability. However, much fewer all‐optical devices are realized based on quasi‐2D perovskites. Although perovskites have large nonlinear optical coefficients, the relaxation progress of excitons and carriers will slow down the response time and reduce the signal contrast of the all‐optical devices. In this paper, the exciton dynamics are investigated under off‐resonance excitation in quasi‐2D perovskite PEA2(FAPbBr3)2PbBr4. The spin‐selective optical Stark effect (OSE) is observed through circularly polarized transient absorption measurements, and a Stark shift of 3.3 meV is achieved under 1.11 eV excitation. The hot‐biexciton cooling process induced by two‐photon absorption is also observed. A spin‐based XNOR gate is demonstrated with a response time of ≈180 fs, and the logical signal contrast is enhanced through the competition of the OSE and the hot‐biexciton effect.

Published: November 2024

AbstractHerein, we report the development of photoredox‐catalyzed N−H insertion of sulfoxonium ylides with amines via oxidative single‐electron transfer (SET). These reactions exhibit broad substrate scope (32 examples) and offer operationally simple, scalable procedures for accessing α‐ketoamides in a single step. Mechanistic studies and control experiments confirm the participation of a photogenerated carbon radical in facilitating the oxidative single‐electron transfer (SET) from the sulfoxonium ylides to initiate the reaction.

Published: November 2024

AbstractAdvancing and deploying Fenton‐inactive Cd that combines excellent catalytic activity, selectivity, and stability remains a serious challenge, predominantly owing to the difficulty in regulating the intrinsic electronic states and local geometric structures of such fully occupied d10s2 configuration. In this work, a combination of experiments and theoretical calculations reveals that the incorporation of boron (B) enables the tuning of the average oxidation state of Cd0 to Cdδ+, facilitating electron localization and implementing a different electrocatalytic preference compared to conventional d10‐electron configurations. The resulting Cd(B) catalyst demonstrates high selectivity (>90% on average) in the O2‐to‐H2O2 conversion, negligible activity loss over 100 h, and a superior H2O2 production rate (15.5 mol∙gcat−1 h−1 at −100 mA). More unexpectedly, the in situ generated H2O2 exhibits a unique advantage over commercial products, selectively oxidizing cinnamaldehyde to benzaldehyde by modulating the practical current.

AbstractRapid and intelligent identification of prostate cancer (PCa) is critical for early diagnosis. Herein, a convenient, reliable, and intelligent strategy is proposed to screen PCa individuals through indirectly quantifying sarcosine (Sar), an early indicator of PCa, in clinical urine samples. Success is achieved by integrating sarcosine oxidase (SOX) as a specific recognition unit; nanozyme‐assisted multicolor intelligent visualization platform as a signal reporter. With the Fe‐MOFs and peroxidase, the synergetic action of SOX and response gold nanorods (Au NRs) is controlled etched to exhibit a multicolored signal. The sensor exhibits excellent linearity with Sar within 1–60 × 10−6 m, boasting a remarkable detection limit of 0.12 × 10−6 m. The RGB value of the display color can be directly extracted using a mobile phone camera. PCa diagnosis can be swiftly made (within 15 min) and directly by identifying two RGB colors (R < 175 or B > 135). The enzyme‐assisted multicolor intelligent visualization platform is adept at detecting minute differences in Sar concentration in urine samples between PCa patients and healthy individuals. The concept of enzyme‐assisted multicolor sensing can be further expanded by modifying the type of immobilized enzymes, providing a valuable guideline for the rational design of multiple probes to measure specific biomarkers in biological samples.

Abstract1,3‐Dioxolane (DOL), with its broad liquid phase temperature window and low Li+‐solvent binding energy, stands out as an ideal solvent candidate for the wide‐temperature and high‐rate electrolytes. Unfortunately, DOL is susceptible to undergo ring‐opening polymerization under common lithium salts, which markedly retards the reaction kinetics. This work introduces the organic basic additive 1,8‐Diazabicyclo[5.4.0]undec‐7‐ene (DBU) to effectively suppress the polymerization, thus achieving compatibility between LiFSI, LiDFOB lithium salts, and DOL. Furthermore, density functional theory (DFT) calculations are utilized to elucidate the underlying mechanisms of DOL polymerization and to clarify how DBU inhibits its polymerization. The resulting electrolyte, devoid of polymer chain formation, forms a weak solvation structure rich in anions, which demonstrates rapid ion transport kinetics in the bulk electrolyte and excellent electrochemical stability at the electrolyte–electrode interfaces (EEIs) simultaneously. When applied to the LiFePO4||graphite full cell, it exhibits exceptional wide‐temperature and high‐rate performance, with specific capacities reaching 101.2 mAh g −1 at room temperature (20 C), 36.9 mAh g−1 at −40 °C (0.5 C), and 118.0 mAh g−1 at 60 °C (20 C). This study significantly guides the development of wide‐temperature, high‐rate electrolytes.

AbstractThe mammalian target of rapamycin (mTOR) is a critical signaling hub for sustaining cancer survival. Targeting mTOR and inducing autophagic cell death downstream of it represent promising therapeutic strategies for cancer prevention. A US Food and Drug Administration‐approved drug library containing 616 small molecules is used to screen anticancer drugs against colorectal cancer (CRC) cells that rely on mTOR. This led to the identification of an antipsychotic drug aripiprazole, which significantly induced mTOR inhibition and autophagic apoptosis in CRC, in vitro and in vivo. The use of drug affinity response target stability identified lysosome‐associated membrane protein 2A (LAMP2a) as a direct target of aripiprazole. LAMP2a‐deficient CRC cells are refractory to aripiprazole. High LAMP2a expression is associated with poor survival of patients with CRC and negatively correlated with expression of ribonuclease inhibitor 1 (RNH1), which is later confirmed as a novel substrate of LAMP2a. Mechanistically, aripiprazole bound to the Lys401–His404 of LAMP2a and repressed its activity, subsequently inactivating RNH1/miR‐99a/mTOR signaling and inducing autophagy‐mediated apoptosis, thereby suppressing tumorigenesis. Liposome‐mediated delivery of aripiprazole in combination with fluorouracil elicited superior therapeutic benefits in CRC, as compared to single treatments, thereby highlighting that aripiprazole may be repurposed as a novel therapeutic agent for CRC treatment.

AbstractThe electric dipoles of proteins in a biolayer determine their dielectric properties through the polarization density P. Hence, its reproducibility is crucial for applications, particularly in bioelectronics. Biolayers encompassing capturing antibodies covalently bound at a biosensing interface are generally preferred for their assumed higher stability. However, surface physisorption is shown to offer advantages like easily scalable fabrication processes and high stability. The present study investigates the effects of electric‐field (EF)‐cycling of anti‐Immunoglobulin M (anti‐IgM) biolayers physisorbed on Au. The impact of EF‐cycling on the dielectric, optical, and mechanical properties of anti‐IgM biolayer is investigated. A reduction of the dispersion (standard deviation over a set of 31 samples) of the measured P values is observed, while the set median stays almost constant. Hence, physisorption combined with EF cycling, results in a biolayer with highly reproducible bioelectronic properties. Additionally, the study provides important insights into the mechanisms of dielectric rearrangement of dipole moments in capturing biolayers after EF‐cycling. Notably, EF‐cycling acts as an annealing process, driving the proteins in the biolayer into a statistically more probable and stable conformational state. Understanding these phenomena enhances the knowledge of the properties of physisorbed biolayers and can inform design strategies for bioelectronic devices.

ABSTRACTBackgroundLaw enforcement workers face a higher risk of cardiovascular disease (CVD), however, employment factors impacting CVD remain systematically understudied, particularly in a national US sample. We describe temporal trends in prevalent CVD including coronary heart disease (CHD), angina, myocardial infarction (MI) and other heart disease; and investigate associations of select employment factors with CVD among law enforcement workers using the National Health Interview Survey (NHIS) from 2006 to 2018.MethodsWe analyzed prevalent CVD in law enforcement workers employed in local, state, and federal establishments using the NHIS, a nationally representative sample of US workers. We estimated odds ratios (OR [95% confidence interval, CI]) of CVD in relation to employment factors using survey‐weighted multivariable logistic regression models adjusted for sociodemographic and traditional CVD risk factors.ResultsAmong 2177 law enforcement workers, mean age 46 years, 19% female, prevalence of CVD was higher among disabled (OR = 5.37; 95% CI: 2.53, 11.38 for aggregate CVD outcome) and retired (OR = 2.14; 95% CI: 1.18, 3.88 for aggregate CVD outcome) workers compared to currently employed workers. Workers employed in smaller (1–24 employees) or larger (≥ 500 employees) departments and those with tenure > 20 years also demonstrated higher prevalence odds of select CVD outcomes. Although not statistically significant, higher prevalence odds across CVD outcomes were observed in local government employees, hourly paid workers, and workers with 10–19 years of tenure.ConclusionsOur study highlights that select employment factors, some previously underexplored, may be associated with prevalent CVD in law enforcement workers. Leveraging national surveys and worker cohorts to enhance surveillance of identified groups in this high‐risk population could help elucidate the role of employment on CVD development and inform workplace interventions.

ABSTRACTThe recent upsurge in the use of common marmosets (Callithrix jacchus) as a desirable model for high‐priority biomedical research has challenged local and global suppliers struggling to provide sufficient numbers of marmosets for large‐scale projects. In laboratories, random male‐female pairings are often unsuccessful, with intervals of several months before attempting alternate pairings. Here we address this challenge through a behavioral task that promotes self‐directed female selection of potential mates to increase the efficiency of breeding in captive marmosets. We created a partner preference test in which nulliparous females (n = 12) had the opportunity to select between two eligible males (n = 23) at a time, in a forced choice test. In this test, both males and females displayed sexual solicitations. However, the females displayed a clear preference for one male by directing affiliative behaviors toward him including proceptive tongue‐flicking, approach, and grooming. Her preference remained consistent across three consecutive test sessions. This method resulted in a 2.5‐fold improvement in breeding success within 90 days compared to random pairings. This cost‐effective and straightforward pairing practice can be used to enhance breeding efficiency in both small and large marmoset colonies.

ABSTRACTIn group‐living primates, male investment in infants is highly variable. Previous research on polygynandrous primates found that male care of infants, whether direct or indirect, may be a means to increase offspring survival, increase social status, invest in future mating opportunities, and/or invest in future social or coalition partners, any of which may increase fitness outcomes. Relationships between male white‐faced capuchins (Cebus imitator) and infants are highly variable, ranging from neutral to highly affiliative during periods of group stability to lethal during times of instability. We used genetic paternity analysis and behavioral observations to investigate the impact of paternity status, female dominance rank, male dominance rank, and infant sex on changes in rates of affiliation (contact and proximity) between capuchin males and females following the birth of an infant (n = 92 dyads). We used generalized linear mixed models and an information theory approach to select models for averaging. We found that overall rates of male‐female affiliation increased following the birth of an infant (contact change: +1.09 ± 2.55%; proximity change: +1.16 ± 3.08%). Infant sex was the only significant explanatory variable; dyads that included males and females who gave birth to male infants experienced a significant increase in their time in contact and proximity in comparison to dyads with females who gave birth to female infants (contact change: p < 0.05 in 2/3 models; proximity change: p < 0.001 in 3/3 models). These findings add to previous data indicating that male capuchins do not recognize their offspring or have the motivation to preferentially invest in their care. We suggest that the observed sex bias may be a form of sex‐specific socialization connected to the importance of forming long‐term cooperative male bonds that are maintained via male parallel dispersal in this species.
