| Abstract | Parts of the Kern County have high nitrate levels in groundwater. A State Water Resources Control Board commissioned report has indicated that crop land agriculture is the main source of nitrates in the groundwater. Annual rainfall is less than 20 cm, thus irrigation is necessary for optimum crop production. A project was undertaken to evaluate current nitrogen fertility and irrigation scheduling in potato production and their contribution, or lack thereof, to nitrate movement in the soil profile and potential nitrate contamination of groundwater. A line-source sprinkler plot area was established to create soil moisture regimes of 120% of target, target (optimum soil moisture for potato growth) and 80% of target. Pre-plant and post-harvest soil samples were collected to a depth of 2 meters. Plant, root and tuber samples were collected and analyzed for nitrogen content. Soil moisture and irrigation amounts were monitored. Plant dry matter and tuber yield increased with each N rate increase. The high N rate increased plant growth disproportionally to the increased tuber yield. Appropriate irrigation scheduling did not produce water movement beyond the effective potato rooting zone. Excessive irrigation moved soil nitrate deeper into the soil profile. |

| Abstract | Background: As advance healthcare directives gain clarity in state legislation in Ireland, anaesthesiologists will come across patients with resuscitation orders that will demand interpretation when encountered perioperatively. Studies show variable perceptions among anaesthesiologists towards the binding nature of resuscitation orders in the context of anaesthesia provision. Currently, knowledge, perceptions and practices of anaesthesiologists in Ireland towards such orders are not known. Methods: A cross-sectional online survey was distributed to anaesthesiologists in adult teaching hospitals. Results: In this cohort, 65.9% of those surveyed did not know if there was a local hospital policy advance healthcare directive containing, do not attempt resuscitation, decisions in the perioperative period in their current hospital; 57.7% did not know if there was a policy for not for resuscitation orders; 74.8% did not know if there are guidelines for the management of patients with resuscitation orders. Irrespective of the presence of an order stating otherwise, 43.9% would initiate resuscitation in the event of any arrest occurring in theatre, with 66.7% initiating resuscitation if secondary to iatrogenesis. Conclusions: By uncovering low self-perceived levels of knowledge and mixed perceptions towards resuscitation orders, the authors hope that the study initiates much-needed conversations on the topic, particularly at a time when advance healthcare directives find a more firm legal footing in Ireland. |

| Abstract | Introduction: Around 20% of intensive care unit (ICU) patients undergo tracheostomy insertion and expect high-quality care concentrating on patient-centered outcomes including communication, oral intake, and mobilization. The majority of data has focused on timing, mortality, and resource utilization, with a paucity of information on quality of life following tracheostomy. Methods: Single center retrospective study including all patients requiring tracheostomy from 2017 to 2019. Information collected on demographics, severity of illness, ICU and hospital length of stay (LOS), ICU and hospital mortality, discharge disposition, sedation, time to vocalization, swallow and mobilization. Outcomes were compared for early versus late tracheostomy (early = <day 10) and age category (≤ 65 vs ≥ 66 years).<br />Results: In total, 304 patients were included and 71% male, median age 59, APACHE II score 17. Median ICU and hospital LOS 16 and 56 days, respectively. ICU and hospital mortality 9.9% and 22.4%. Median time to tracheostomy 8 days, 8.55% open. Following tracheostomy, median days of sedation was 0, time to noninvasive ventilation (NIV) 1 day (94% of patients achieving this), ventilator-free breathing (VFB) 5 days (72%), speaking valve 7 days (60%), dynamic sitting 5 days (64%), and swallow assessment 16 days (73%). Early tracheostomy was associated with shorter ICU LOS (13 vs 26 days, Conclusion: Patient-centered outcomes are a worthy goal to consider when selecting patients for tracheostomy in addition to mortality or timing alone, including in older patients. |

| Abstract | In this review, we provide a detailed coverage of multi-sensor fusion techniques that use RGB stereo images and a sparse LiDAR-projected depth map as input data to output a dense depth map prediction. We cover state-of-the-art fusion techniques which, in recent years, have been deep learning-based methods that are end-to-end trainable. We then conduct a comparative evaluation of the state-of-the-art techniques and provide a detailed analysis of their strengths and limitations as well as the applications they are best suited for. |

| Abstract | A comprehensive review of medical examiner data was undertaken of all hanging deaths in the Canadian Maritime province of Newfoundland and Labrador from 1982 to 2021. A total of 811 cases were identified representing suicidal, accidental, and undetermined manners of death. Variables examined included age; sex; seasonality; ligature type; location; time since death; prior attempts/suicidal ideation; presence/absence of a suicide note; and presence/absence of alcohol and drugs. Data subsets were generated, and additional analysis was conducted for hangings involving females; suicidal hangings occurring in the region of Labrador; and those who hanged themselves outdoors. Results indicate that females are choosing to kill themselves by hanging in rapidly increasing numbers. Outdoor suicides by hanging were more common in Newfoundland and Labrador (22.1%) than previously reported in Alberta (11.5%), Texas (5%), and Turkey (12-13%). Unique trends in seasonality were revealed, as were repeated incidents of suicidal clusters. The age distribution was skewed strongly toward youths (10 to 22 years of age), particularly in Labrador. Although Labrador represents only 5% of the total provincial population, it produced 20.1% of the total suicidal hangings in the study. The suicide rate in Canada has decreased by 24% over the past 40 years, yet the rates of suicidal hangings nationally and in Newfoundland and Labrador have increased during the same time period. With a better understanding of the circumstances under which people commit suicide by hanging within the province, it may be possible to target at-risk groups to prevent future cases. |

| Abstract | The placenta is the interface between mother and fetus in all eutherian species. However, our understanding of this essential organ remains incomplete. A substantial challenge has been the syncytial cells of the placenta, which have made dissociation and independent evaluation of the different cell types of this organ difficult. Here, we address questions concerning the ontogeny, specification, and function of the cell types of a representative hemochorial placenta by performing single nuclei RNA sequencing (snRNA-seq) at multiple stages of mouse embryonic development focusing on the exchange interface, the labyrinth. Timepoints extended from progenitor-driven expansion through terminal differentiation. Analysis by snRNA-seq identified transcript profiles and inferred functions, cell trajectories, signaling interactions, and transcriptional drivers of all but the most highly polyploid cell types of the placenta. These data profile placental development at an unprecedented resolution, provide insights into differentiation and function across time, and provide a resource for future study. |

| Abstract | High-resolution digital topographic data permit morphological analyses of glacial processes in detail that was previously infeasible. High-level glaciofluvial erosional scars in central Pennsylvania, identified and delimited using LiDAR data, define the approximate ice depth during a pre-Wisconsin advance, >770,000BP, on a landscape unaffected by Wisconsin glaciation. Distinctive scars on the prows of anticlinal ridges at 175â350m above the valley floor locate the levels of subice meltwater channels. A two-component planar GIS model of the ice surface is derived using these features and intersected with a digital model of contemporary topography to create a glacial limit map. The map is compared to published maps, demonstrating the limits of conventional sediment-based mapping. Additional distinctive meltwater features that were cut during deglaciation are modeled in a similar fashion. |

| Abstract | The human placenta contains two specialized regions: the villous chorion where gases and nutrients are exchanged between maternal and fetal blood, and the smooth chorion (SC) which surrounds more than 70% of the developing fetus but whose cellular composition and function is poorly understood. Here, we use single cell RNA-sequencing to compare the cell types and molecular programs between these two regions in the second trimester human placenta. Each region consists of progenitor cytotrophoblasts (CTBs) and extravillous trophoblasts (EVTs) with similar gene expression programs. While CTBs in the villous chorion differentiate into syncytiotrophoblasts, they take an alternative trajectory in the SC producing a previously unknown CTB population which we term SC-specific CTBs (SC-CTBs). Marked by expression of region-specific cytokeratins, the SC-CTBs form a stratified epithelium above a basal layer of progenitor CTBs. They express epidermal and metabolic transcriptional programs consistent with a primary role in defense against physical stress and pathogens. Additionally, we show that SC-CTBs closely associate with EVTs and secrete factors that inhibit the migration of the EVTs. This restriction of EVT migration is in striking contrast to the villous region where EVTs migrate away from the chorion and invade deeply into the decidua. Together, these findings greatly expand our understanding of CTB differentiation in these distinct regions of the human placenta. This knowledge has broad implications for studies of the development, functions, and diseases of the human placenta. |
