title: Preterm Birth Initiative-Rwanda antenatal care and postnatal care providers survey

description: Background: The East Africa Preterm Birth Initiative-Rwanda began a
 cluster randomized controlled trial of group antenatal care (ANC) and
 postnatal care (PNC) in Rwanda in 2017. That trial will report its primary
 outcome, gestational length at birth, after data collection concludes in
 2019. This nested study includes providers of ANC and/or PNC at the 18
 health centers randomized to provide the group model of ANC/PNC and the 18
 health centers randomized to continue providing ANC/PNC in the
 traditional, individual visit model. The objective of this study is to
 understand the experiences of providers of group ANC/PNC and compare their
 job satisfaction and perceived stress with individual ANC/PNC providers.
 Methods: We collected both quantitative and qualitative data from
 providers (nurses and midwives) who were recruited by health center
 directors to participate as group ANC and PNC facilitators at intervention
 sites and from a similar number of providers of standard ANC and PNC at
 control sites. Quantitative data was collected with questionnaires
 administered at baseline and approximately 9 months later (follow up).
 Qualitative data was collected in 3 focus groups of group ANC/PNC
 providers conducted one year after group care began. Results: Eighty-six
 percent of nurses and midwives surveyed who implemented group ANC and PNC
 reported that they prefer group care to the traditional individual model
 of ANC and PNC. Perceived stress levels and job satisfaction results were
 similar between groups. Mixed focus group discussions among both nurses
 and midwives experienced in group ANC and PNC suggest that the group model
 of care has advantages for both service beneficiaries and providers. When
 providers described implementation challenges, their peers in the focus
 groups offered them suggestions to cope and improve service delivery.
 Discussion: These results are consistent with studies of providers of
 group ANC and PNC in other LMIC contexts with respect to the perceived
 benefits of group care. This study adds new insights into the ways peer
 providers can help one another solve implementation problems. When given
 the opportunity to meet as a group, these study participants offered one
 another peer support and shared knowledge about best practices for
 successful implementation of group ANC/PNC.   This trial is
 registered at clinicaltrials.gov as NCT03154177.

title: Emergency Intracranial Stenting in Acute Stroke: Predictors for Good Outcome and for Complications

description: Background: Stent-retriever thrombectomy (SRT) is the first-line therapy
 in acute stroke with intracranial large vessel occlusion (LVO). However,
 SRT may fail in patients with intracranial atherosclerotic stenosis or
 dissection, where rescue stent angioplasty (RSA) may be the only treatment
 option to achieve permanent recanalization. Purpose: This study aims at
 identifying predictors for good outcome and for complications in a large
 multicenter cohort of these patients. Methods: We performed a
 retrospective analysis of patients with LVO who were treated with RSA
 after SRT between 2012 and 2018 in seven neurovascular centers. We defined
 two binary outcomes (yes/no): 1) functional clinical outcome after 90 days
 (good (modified Rankin Scale (mRS) 0-2) and poor (mRS 4-6)) and 2)
 symptomatic intracerebral hemorrhage (sICH) in the immediate
 post-interventional phase. The impacts of clinical, radiological and
 interventional parameters on outcome were analysed. Results: 210 patients
 out of 4751 thrombectomies (4.4%) were included with 136 (64.8%) anterior
 circulation and 74 (35.2%) patients with posterior circulation LVO.
  In 22 patients sICH occured, 19 (86.4%) after anterior and 3
 (13.6%) after posterior circulation LVO. After 3 months 73 /163 (44.8%)
 patients had a good clinical outcome.  A higher NIHSS at
 admission (adjusted OR, 1.10, P=0.002), a higher premorbid mRS (adjusted
 OR, 2.02, P =0.049) and a mTICI (modified thrombolysis in cerebral
 infarction) score of 0-2a in the final run after stenting (adjusted OR,
 23.24 per maneuvre, P &lt;0.001) were independent predictors of poor
 functional outcome. Conclusions: The use of RSA can be considered for
 acute intracranial LVO in cases after unsuccessful SRT. The likelihood of
 sICH is higher in anterior circulation stroke.

title: Detecting an effect of group size on individual responses to neighboring groups in gray-cheeked mangabeys (Lophocebus albigena)

description: Evolutionary game theory posits that competitive ability affects the
 initiation of conflicts. When contests occur among groups, competitive
 ability is generally measured as the size of the group and larger groups
 are expected to win against smaller groups. However, in some cases,
 individual participation during intergroup conflicts appears unaffected by
 competitive ability. To test whether these instances might be due to an
 unduly strict definition of participation, I re-evaluate the responses of
 grey-cheeked mangabeys (Lophocebus albigena) to the calls of real and
 simulated neighboring groups. In contrast with previous analyses, I
 consider multiple measures of group size, treat movement responses as a
 continuous variable, and evaluate individual responses (N = 201 focal
 follows). Males made stronger approaches toward calling neighbors than
 females, though both sexes tended to retreat from groups that were
 &lt;500m away and to approach more distant neighbors. Individuals in
 small groups retreated while those in large groups both approached and
 retreated. There was no evidence of a collective action problem: in fact,
 approaches were more likely within large groups than small groups, and
 approaches were stronger when at least one other individual within the
 focal group made a dramatic approach toward the caller. The absence of a
 group size effect is attributable to coarse methods in some contexts, and
 to a stronger effect of collective behavior or resource-related motivation
 in other contexts.

title: Temporal Inflection Points in Decorated Pottery: a Bayesian Refinement of the Late Formative Chronology in the Southern Lake Titicaca Basin, Bolivia

description: The Late Formative Period immediately precedes the emergence of Tiwanaku,
 one of the earliest South American states, yet is one of the most poorly
 understood periods in the southern Lake Titicaca Basin (Bolivia). In this
 paper, we refine this period’s ceramic chronology with large sets of dates
 from eight sites, focusing on temporal inflection points in decorated
 ceramic styles. These points, estimated here by Bayesian models, index
 specific moments of change: (1) cal AD 140 (110–170, 68% probability) –
 first deposition of Kalasasaya red-rimmed and zonally-incised styles, (2)
 cal AD 210 (170–240, 68% probability) – final deposition of
 Kalasasaya zonally-incised vessels, (3) cal AD 420 (390–440, 68%
 probability) – final deposition of Kalasasaya red-rimmed vessels, and (4)
 cal AD 590 (550–630, 68% probability) – first deposition of
 Tiwanaku Redwares. These four modeled boundaries anchor an updated Late
 Formative chronology, which includes the Initial Late Formative phase, a
 newly identified decorative hiatus between the Middle and Late Formative
 periods. The models place Qeya and transitional vessels between inflection
 points 3 and 4 based on regionally consistent stratigraphic sequences.
 This more precise chronology will enable researchers to explore the
 trajectories of other contemporary shifts during this crucial period in
 Lake Titicaca Basin’s prehistory.

title: Sex-specific floral attraction traits in a sequentially hermaphroditic species

description: The examination of sexual dimorphism in plants has primarily been
 restricted to dioecious taxa. However, most angiosperms produce cosexual
 flowers in which male and female function are separated temporally, which
 may also generate sexual dimorphism (between the male and female stages of
 floral lifespan). The temporal separation between male and female function
 in such flowers may be associated with variation in traits that influence
 pollinator attraction and may function to minimize self-fertilization or
 to maximize sex-specific fitness. In this study, we describe variation in
 floral color, pattern and size across discrete functional sex stages
 within flowers, and between individuals of Clarkia unguiculata
 (Onagraceae).  In addition, we examine the effects of these
 floral traits on pollen receipt (female fitness). We use a combination of
 photographic techniques and image analysis to measure floral attributes in
 225 greenhouse grown individuals across stages of floral development
 associated with functional sex. We use ~180 individuals in experimental
 arrays in the field to determine the independent effects of each floral
 trait on pollen receipt. Male-phase and female-phase flowers of C.
 unguiculata display distinct pollinator attraction traits. Petal area,
 Ultraviolet (UV) nectar guide area, and flower color differ significantly
 across the functional sex stages of C. unguiculata. Flowers with large
 UV-absorbing nectar guides receive more pollen than those with small
 nectar guides. Flowers with blue and green mean reflectance values that
 differ most from background foliage also receive more pollen than those
 with reflectance values that are similar to foliage.

title: Rhythm of Attention

description: Modulation patterns are known to carry critical predictive cues to signal
 detection in complex acoustic environments.  The current study
 investigated the persistence of masker modulation effects on
 post-modulation detection of probe signals.  Hickok et al. (2015)
 demonstrated that thresholds for a tone pulse in stationary noise follow a
 predictable periodic pattern when preceded by a 3-Hz amplitude modulated
 masker.  They found entrainment of detection patterns to the
 modulation envelope lasting for approximately 2 cycles after termination
 of modulation.  The current study extends these results to a wide
 range of modulation rates by mapping the temporal modulation transfer
 function for persistent modulatory effects.  We found significant
 entrainment to modulation rates of 2 and 3 Hz, a weaker effect at 5 Hz,
 and no entrainment at higher rates (8 to 32 Hz).  The effect
 seems critically dependent on attentional mechanisms, requiring temporal
 and level uncertainty of the probe signal.  We also investigated
 whether entrainment extends to more complex periodic patterns by using
 driving modulators comprising two simultaneous rates (2 & 3 Hz or
 3 & 5 Hz).  No persistence was observed for these complex
 patterns.  Our findings suggest that the persistence of
 modulatory effects on signal detection is lowpass in nature and attention
 based, extending only to simple envelope patterns.

title: Salinity and Velocity in Lower South San Francisco Bay

description: In order to measure salinity gradients in the longitudinal, lateral, and
 vertical directions, a mesh of nine Ruskin RBR XR-420 CTDs and two Seabird
 SBE-37's were placed in various positions in all three dimensions.
 Lines 1, 2, 3, and 4 were placed in the channel. Lines 5 and 6 were placed
 in the shallows, lateral to line 2. Line 1 has two CTD's attached at
 the top and bottom of the water column. Lines 2 and 3 have a top, middle,
 and bottom CTD. Line 4 has one CTD located near the surface of the water
 column. Lines 5 and 6 each have a Seabird attached at the surface of the
 water column. The RBRs and Seabirds measured conductivity, pressure
 (depth), and temperature, and calculated salinity, at one minute
 intervals. The RBR XR-420 CTDs (Seabird SBE 37s) have a temperature
 accuracy of  +/-0.002 deg C and pressure accuracy of 0.05%. Two
 Teledyne RD Instruments (RDI) 1200 kHz Workhorse Monitor Acoustic Doppler
 Current Profilers (ADCP) were deployed at locations 2 and 3, and were
 tethered to the CTD lines by a bottom cable. The moored ADCPs were
 programmed to measure over a 12 meter water column with a vertical
 resolution of 0.25 meters with the first bin located 0.81 meters from the
 sea floor. The ADCPs, like the RBRs and Seabirds, collect ensemble
 averages every minute.

title: Data from: Forest-type specialization strongly predicts avian responses to tropical agriculture

description: Species’ traits influence how populations respond to land-use change.
 However, even in well-characterized groups such as birds, widely studied
 traits explain only a modest proportion of the variance in response across
 species. Here, we show that associations with particular forest types
 strongly predict the sensitivity of forest-dwelling Amazonian birds to
 agriculture. Incorporating these fine-scale habitat associations into
 models of population response dramatically improves predictive performance
 and markedly outperforms the functional traits that commonly appear in
 similar analyses. Moreover, by identifying habitat features that support
 assemblages of unusually sensitive habitat-specialist species, our model
 furnishes straightforward conservation recommendations. In Amazonia,
 species that specialize on forests along a soil–nutrient gradient (i.e.
 both rich-soil specialists and poor-soil specialists) are exceptionally
 sensitive to agriculture, whereas species that specialize on floodplain
 forests are unusually insensitive. Thus, habitat specialization per se
 does not predict disturbance sensitivity, but particular habitat
 associations do. A focus on conserving specific habitats that harbour
 highly sensitive avifaunas (e.g. poor-soil forest) would protect a
 critically threatened component of regional biodiversity. We present a
 conceptual model to explain the divergent responses of habitat specialists
 in the different habitats, and we suggest that similar patterns and
 conservation opportunities probably exist for other taxa and regions.

title: Model weights for Lymphoid Aggregates Segmentation (in Pytorch 1.0.1)

description: Allograft rejection is a major concern in kidney transplantation.
 Inflammatory processes in patients with kidney allografts involve various
 patterns of immune cell recruitment and distributions. Lymphoid aggregates
 (LAs) are commonly observed in patients with kidney allografts and their
 presence and localization may correlate with severity of acute rejection.
 Alongside with other markers of inflammation, LAs assessment is currently
 performed by pathologists manually in a qualitative way, which is both
 time consuming and far from precise. Here we present the first automated
 method of identifying LAs and measuring their densities in whole slide
 images of transplant kidney biopsies. We trained a deep convolutional
 neural network based on U-Net on 44 core needle kidney biopsy slides,
 monitoring loss on a validation set (n=7 slides). The model was
 subsequently tested on a hold-out set (n=10 slides). We found that the
 coarse pattern of LAs localization agrees between the annotations and
 predictions, which is reflected by high correlation between the annotated
 and predicted fraction of LAs area per slide (Pearson R of 0.9756).
 Furthermore, the network achieves an auROC of 97.78 ± 0.93% and an IoU
 score of 69.72 ± 6.24 % per LA-containing slide in the test set. Our study
 demonstrates that a deep convolutional neural network can accurately
 identify lymphoid aggregates in digitized histological slides of kidney.
 This study presents a first automatic DL-based approach for quantifying
 inflammation marks in allograft kidney, which can greatly improve
 precision and speed of assessment of allograft kidney biopsies when
 implemented as a part of computer-aided diagnosis system.
