Summary
Globally, primates are experiencing the pressures of anthropogenic influences altering natural landscapes. Given the interconnectedness of land use and species conservation, it is vital to understand how primates move within their environments and how they may respond to future land-use changes. Herein, we used unmanned aerial vehicle (UAV) vegetation surveys and direct behavioural observations to determine how living in a degraded forest has influenced a wild siamang group in northern Sumatra. Within this population, we found a high level of folivory, relatively infrequent territorial long calls, reused routes, and a preference for areas that corresponded with canopy topography high in elevation. These results show that forest degradation can affect the ranging patterns and land-use behaviour of siamangs. To conserve this species and others that display a comparable response to changes in their environment, we need to prevent further degradation before populations are separated and unable to adapt to the limitations that come with human-mediated landscape changes.

Background:
Coronavirus Disease 2019 (COVID-19) instigated a flurry of clinical research activity. The unprecedented pace with which trials were launched left an early void in data standardization, limiting the potential for subsequent data pooling. To facilitate data standardization across emerging studies, the National Heart, Lung, and Blood Institute (NHLBI) charged two groups with harmonizing data collection, and these groups collaborated to create a concise set of COVID-19 Common Data Elements (CDEs) for clinical research.
Methods:Our iterative approach followed three guiding principles: 1) draw from existing multi-center COVID-19 clinical trials as precedents, 2) incorporate existing data elements and data standards whenever possible, and 3) alignment to data standards that facilitate data sharing and regulatory submission. We also supported rapid implementation of the CDEs in NHLBI-funded studies and iteratively refined the CDEs based on feedback from those study teams
Results:The NHLBI COVID-19 CDEs are publicly available and being used for current COVID-19 clinical trials. CDEs are organized into domains, and each data element is classified within a three-tiered prioritization system. The CDE manual is hosted publicly at https://nhlbi-connects.org/common_data_elements with an accompanying data dictionary and implementation guidance.
Conclusions:The NHLBI COVID-19 CDEs are designed to aid data harmonization across studies to achieve the benefits of pooled analyses. We found that organizing CDE development around our three guiding principles focused our efforts and allowed us to adapt as COVID-19 knowledge advanced. As these CDEs continue to evolve, they could be generalized for use in other acute respiratory illnesses.

Several application modes and methods (schemes) of using herbicides are available to control undesirable vegetation on electric transmission line rights-of-way (ROW). Preferential use of a management scheme can be based on its cost effectiveness, i.e., degree of vegetation control and treatment cost. A treatment that increases/maintains desirable plants, decreases/maintains undesirable plants, and has relatively low cost, can be considered cost effective. Three common herbicides, 2,4-D, picloram and triclopyr, were applied in the field to test treatment mode (selective and nonselective) and method (cut stump, basal, and stem-foliar) effects on cost effectiveness during initial clearing and first and second conversion cycles on one electric transmission line ROW in Upstate New York. Clear or selective cutting with no herbicide was most cost effective during initial clearing. Nonselective and selective stem-foliar schemes were most cost effective during the first and second conversion cycles, respectively.

Reduced graphene oxide (RGO) has the advantage of an aqueous and industrial-scalable production route. However, one of the main limitations that prevent the use of RGO in electronics is the high electrical resistance deviation between fabricated chips. In this article, we present the novel growth of RGO which can bridge the gaps in-between existing flakes and thus reduce the electrical resistance standard deviation from 80.5 % to 16.5 %. The average resistivity of the treated RGO of ∼ 3.8 nm thickness was 200 Ω/square. The study uses an atmospheric-pressure chemical vapour deposition (CVD) system with hydrogen and argon gas bubbling through ethanol before entering the furnace. With a treatment of 2 hours, 100 % of the silicon dioxide substrate was covered with RGO from an initial 65 % coverage. This technology could enable large-scale application of RGO use in practical electronic devices.
