“…Some literatures have mentioned that the mechanochemical method can easily create defects (such as dislocations) to afford non-stoichiometric compounds, and the reaction process/mechanism can be material-dependent [7,[35][36][37]. Among iron phosphide alloys, to the best of our knowledge, FeP 4 single phase has not been synthesized through the mechanochemical method yet, as other impurity phases such as FeP and/or FeP 2 are always found [14,38,39]. This might be due to the partial sublimation of phosphorus during the high energy ball-milling, as well as the special thermodynamic equilibrium achieved by this specific reaction.…”

Fe-P alloys with high phosphorous content have been targeted as promising anode materials because of their high theoretical capacity. However, the synthesis and cycling performance remain great challenges. Hereby FeP y (3≤y≤4) nanoparticles are facilely synthesized through a dry mechanochemical method by reacting iron and red phosphorus powders in an inert atmosphere. The morphology and crystal structure of this material are characterized by SEM and XRD, respectively, while the electrochemical performance is evaluated by a number of different techniques. The 1 st and 2 nd discharge capacity of FeP y reaches 1984 mAh/g and 1486 mAh/g, respectively, and after 10 cycles at 0.03 mA cm-2 (20 mA g-1 , 0.03 C), the capacity remains 1089 mAh/g with a coulombic efficiency of 97%, much higher than the reported results to date. The cyclability of this material becomes fairly better at a higher current density, but the specific capacity is lower compared to that of the smaller current density. By adding fluoroethylene carbonate (FEC) to the electrolyte, the cycling performance of this material was improved. The EIS analysis has also been performed in order to better understand the capacity fade mechanism of FeP y .

“…copulation calls: Semple, 2001), interindividual signals in solitary species (e.g. estrus calls: Buesching, Heistermann, Hodges, & Zimmermann, 1998), or on mate defense and the strengthening of pair-bonds (Caselli et al, 2014;Cowlishaw, 1996;Geissmann & Orgeldinger, 2000). Historically, sexual signals have been defined in part by their sexual dimorphism (Darwin, 1871;Andersson, 1982).…”

“…Historically, sexual signals have been defined in part by their sexual dimorphism (Darwin, 1871;Andersson, 1982). Although callitrichine long calls are not canonically dimorphic, ornamented sexual signals, nor are they overtly different to the human ear, they do differ significantly by sex (Masataka, 1987;Norcross & Newman, 1993;Robakis et al, 2018). Given that long calls can and do serve multiple socially important functions in primates, such as intragroup coordination and resource defense (Wich & Nunn, 2002), it is possible that callitrichine long calls act as sexual signals in addition to other performing other functions (Bergman & Sheehan, 2013;Casselli et al, 2018).…”

“…Visual scanning of the environment and attention toward the speaker were both regarded as reactive behaviors, as they are common callitrichid reactions to startling or potentially dangerous stimuli and are often used to assess reactions during playback experiments (Barros et al, 2004;Caine 1984;Kirchhof & Hammerschmidt 2004;Koenig 1998). Following earlier research, we also included scentmarking, and approaches toward or retreats away from the speaker as reactive behaviors (Masataka, 1987;Waser, 1977;. Foraging, grooming, resting, and lateral, undirected movement neither toward nor away from the speaker were classified as non-reactive behaviors.…”

Vocal Transmission of Breeding Status May Facilitate Dispersal in a Cooperative Breeding Primate

Social complexity may drive complexity in communicative systems due to an individual's need to navigate unpredictable interactions with multiple conspecifics. Cooperative breeding primates (marmosets and tamarins; family: Callitrichidae) live in groups with moderate to high reproductive skew, particularly in females, whereby sexually mature individuals are frequently prevented from breeding. Remarkably, dispersal from natal groups is not stereotyped upon reaching reproductive maturity. Individuals are often observed remaining in their natal groups until the same-sex breeder in their group or a neighboring group dies, experiencing hormonal reproductive suppression, aggression, and limited access to potential mates. Here we examined whether emperor tamarins (Saguinus imperator) might use vocal signals to reduce dispersal risks and maximize the likelihood of attaining a breeding position. Using six consecutive years of mark-recapture data, we showed that sexually mature non-breeders (herein "secondary breeders") are more likely to leave their groups from one year to the next than sexually mature breeders ("primary breeders"). This confirmed that, unlike primary breeders who do not need to disperse in order to reproduce, secondary breeders are choosing to accept the risks associated with dispersal and emigrating from their natal groups. We used neural networks to classify vocalizations according to individual breeding status, and conducted a series of playback experiments which demonstrated that tamarins discriminated between the calls of primary and secondary breeders. Our data support the hypotheses that secondary breeders disperse to increase mating opportunities and use vocalizations to signal their availability to potential mates. This species of cooperative breeder appears to use vocalization to navigate its social and reproductive systems, minimizing risks of dispersal and in turn increasing the likelihood of reproductive success. This research has important implications for our understanding of sexual signaling, partner choice, and reproductive success in cooperative breeders.

“…The different relation of AX and AV to mood-related psychiatric burden could be attributed to the contrasting coping strategies connected to these attachment dimensions: Dysfunctional emotional regulation [42] and heightened distress resulting from hyperactivating strategies [25] likely underlie the connection between AX and mood-related psychiatric burden. Conversely, the deactivating strategies associated with AV that are defined by a lack of visible negative emotions, as well as a high level of unconscious distress [43], might explain the missing connection between AV and mood-related psychiatric burden.…”

The relationship between existential well-being and mood-related psychiatric burden in Indian young adults with attachment deficits: a cross-cultural validation study

Background: Attachment and spirituality are thought to have deep evolutionary roots but are always interpreted within the framework of culture, religion and personal beliefs. While insecure attachment has been observed to be positively related with psychopathology, a positive mental health effect has often been described for spirituality. To examine the cross-cultural validation of previous research focused on Austrian young adults with Western socialization, we attempt to replicate our study examining the influence spirituality has on the connection between insecure attachment and mood-related psychiatric burden with Indian young adults. Methods: We investigated Avoidant (AV) and Anxious (AX) Attachment (ECR-RD), Religious (RWB) and Existential (EWB) Well-Being (MI-RSWB), and mood-related psychiatric burden (Anxiety, Depression, Somatization; BSI-18) in 443 (31% female) Indian young adults (age range: 18-30 years) with a Hindu upbringing. Results: Compared to young adults with a Roman Catholic upbringing in a Western socialization, Indian participants did not differ in AX and EWB but scored higher in mood-related psychiatric burden (eta 2 = .04), AV (eta 2 = .14), as well as RWB (eta 2 = .28; all p < .01). As in previous research only AX (β = .40) positively predicted mood-related psychiatric burden (ΔR 2 = .15, all p < .01), while EWB was an additional negative predictor (β = −.11, p < .05). Conclusions: Our findings emphasize the universal importance of attachment and spirituality for mental health as well as the potential influence of socialization on their development. Furthermore, they underline that Existential Well-Beingincluding hope for a better future, forgiveness, and the experience of sense and meaningappears to have a compensating effect on the relation between insecure attachment and impaired mental health.
