B-040 Direct Aspiration of Cryogenic Matrix Tubes on the Siemens Atellica System With Epic-Beaker Integration of External Barcode IDs for Analysis Small Volume Biobanked Specimens

Abstract Background Most core chemistry and immunochemistry clinical analyzers are designed for direct sampling of primary blood tubes with volumes ranging from 3.5-10 mL. This limits analysis of low volume pediatric specimens and biobanked aliquoted samples from clinical trials without manual technologist intervention. This work outlines a microsampling and data transmission scheme for analysis of 500 uL aliquots of biobanked serum collected for the Nutrition for Precision Health study powered by the NIH All of Us Research Program without relabeling secondary aliquot tubes after receipt. Methods Commercial plastic clip bearings sourced from IGUS (LCM-08-02) were used to stabilize the matrix tube in a standard 5 mL Sarstedt aliquot tube. 96-well format Matrix Tubes (ThermoFisher 3719-11) with pre-printed 10-digit side barcodes were programmed in the Atellica software as a custom false bottom tube with specifications height 75 mm, diameter 12 mm, bottom offset 41 mm and were loaded using a dedicated false bottom tray. Manifest files (.csv) containing the sample ID, clinical trials participant ID, collection date/time, age and sex were ingested into Epic via an Incoming Orders HL7 interface. Non-human patient records were generated using the participant ID as an external patient ID and patient name and calculating the Date of Birth based on the age in years given in the manifest file. Test orders were created based on assigned testing for the sample ID in the manifest. The sample ID corresponding the preprinted Matrix Tube barcode ID was inserted into the Epic container identifier field. Results Test orders were automatically transmitted to the Atellica Data Manger (ADM) allowing specimens to be run on the Atellica System (CH and IM modules) and results transmitted to Epic utilizing the established Data Innovations (DI) interface and processes used for patient samples without the need for Epic generated labels. Successful scanning and recognition of Matrix Tube barcodes was 100%. Complete aspiration of a Comprehensive Metabolic Panel, Lipid Panel, Iron, TIBC, hsCRP, insulin, and H, I, L indices occurred for 50% of samples tested without intervention. Approximately 250 uL of the 500 uL aliquot remained after aspiration of all tests (247.7 uL total volume) from the Matrix Tube. No probe crashes were observed despite the narrower 8 mm diameter of the Matrix Tubes versus the standard 12- or 13-mm diameter of primary blood collection tubes. Conclusions This Epic-DI-ADM data workflow and microsampling adaptation for Matrix Tube aspiration allows greater container type flexibility for the receipt and analysis of external samples delivered in non-primary blood tubes for clinical laboratories. Future work involving adjustment of the false bottom tube offset depth may reduce unusable sample volume allowing for a higher percentage of complete aspiration without intervention. This work is significant because it suggests existing clinical analyzers are easily adaptable to microsampling smaller volume tubes without significant effort.

Facial Wrinkle Detection with Multiscale Spatial Feature Fusion Based on Image Enhancement and ASFF-SEUnet

Wrinkles, crucial for age estimation and skin quality assessment, present challenges due to their uneven distribution, varying scale, and sensitivity to factors like lighting. To overcome these challenges, this study presents facial wrinkle detection with multiscale spatial feature fusion based on image enhancement and an adaptively spatial feature fusion squeeze-and-excitation Unet network (ASFF-SEUnet) model. Firstly, in order to improve wrinkle features and address the issue of uneven illumination in wrinkle images, an innovative image enhancement algorithm named Coiflet wavelet transform Donoho threshold and improved Retinex (CT-DIR) is proposed. Secondly, the ASFF-SEUnet model is designed to enhance the accuracy of full-face wrinkle detection across all age groups under the influence of lighting factors. It replaces the encoder part of the Unet network with EfficientNet, enabling the simultaneous adjustment of depth, width, and resolution for improved wrinkle feature extraction. The squeeze-and-excitation (SE) attention mechanism is introduced to grasp the correlation and importance among features, thereby enhancing the extraction of local wrinkle details. Finally, the adaptively spatial feature fusion (ASFF) module is incorporated to adaptively fuse multiscale features, capturing facial wrinkle information comprehensively. Experimentally, the method excels in detecting facial wrinkles amid complex backgrounds, robustly supporting facial skin quality diagnosis and age assessment.

Research on the Slip Rate Control of a Power Shift Tractor Based on Wheel Speed and Tillage Depth Adjustment

The existing control methods for the slip rate of the driving wheel of a test prototype have limitations that cause low-quality tillage and finishing operations. We propose a slip rate control method based on the dual factor adjustment of wheel speed and tillage depth, taking the power shift tractor New Holland T1404 as an example to verify the algorithm. This method employs the wheel speed control principle based on the power transmission ratio calculation, throttle adjustment, and wheel speed control methods, as well as the slip rate control method, with wheel speed–slip rate control as the main factor and tillage depth–slip rate control as the secondary factor. A tractor test prototype was built to validate the method. The wheel speed control method enabled the tractor to accurately control the wheel speed under three working conditions: no load on a cemented ground, no load in a field, and subsoiling operation. For the subsoiling operation, the slip rate control method gradually reduced the tractor wheel speed when the slip rate of the tractor’s drive wheel was too high until it met the requirements. When the wheel speed was adjusted to the lower limit, suspension control was performed to reduce the tillage depth and improve vehicle trafficability. In the 130 s validation test, it took 14.1 s for the tractor with the slip rate control function to have a wheel slip rate exceeding 20%, which was 25.4% lower than that of the tractor without this function. The proposed method controls the slip rate within the optimal range while ensuring maximum operation quality (tillage depth).

Buried Layer Low Gain Avalanche Diodes

We report on the design, simulation and test of Low Gain Avalanche Diodes (LGADs) which utilize a buried gain layer. The buried layer is formed by patterned implantation of a 50-micron thick float zone substrate wafer-bonded to a low resistivity carrier. This is then followed by epitaxial deposition of a ≈ 3 micron-thick high resistivity amplification region. The topside is then processed with junction edge termination and guard ring structures and incorporates an AC-coupled cathode implant. This design allows for independent adjustment of gain layer depth and density, increasing design flexibility. A higher gain layer dopant density can also be achieved by controlling the process thermal budget, improving radiation hardness. A first set of demonstration devices has been fabricated, including a variety of test structures. We report on TCAD design and simulation, fabrication process flow, and preliminary measurements of prototype devices.

A Unified Representation of Control Logic in Human-Ultrasound Machine Interaction.

Advances in human-computer interaction (HCI) technologies have granted sonographers and radiologists a much improved user experience when operating different ultrasound (US) machines. Continued HCI improvements in US would benefit from a systematic study of the HCI control logic used in this domain. Such a study has not been presented previously and is the subject of this paper. We surveyed sonographers to determine the most frequently used controls in US machines. We standardized the representation of the US machine HCI control logic by using the unified modelling language (UML). We used UML diagrams to analyze the HCI control logic of 10 different cart-based US machines from several major manufacturers, and we discovered that the control logic for the most frequently used functions are identical. While this control logic does not follow an established standard, it has been commonly adopted. Using the UML for the visualization and formulation of control logic, we can target logically optimal interactions (whose operation steps cannot be further reduced), e.g., adjustment of B-mode gain, frequency and depth, and can derive methods to simplify logically sub-optimal interactions, e.g., the pointing and selecting operation, as well as image measurements.Our study provides insights into existing HCI approaches used in US machines and establishes a rigorous UML-based framework for future US machine design to improve interoperability, efficiency and ease-of-use.

Signal-to-noise ratio improvement of the signal immersed in the strong background noise using a bistable circuit with tunable potential-well depth

Fault detection is one of the primary tasks in aerospace engineering. A clean target signal is required to improve the detection quality. This paper introduces a bistable nonlinear circuit with tunable potential-well depth (TPWD) to improve the signal-to-noise ratio (SNR) of the signal immersed in strong noise background. The TPWD bistable circuit utilizes the tunable bifurcation feature of the nonlinear dynamics to extract the target signal under different noise conditions. The theory of the circuit is first presented. Then, under noise circumstances, the fidelity of the mathematical model of the circuit is validated through experiments. Results show that owing to the TPWD bistable circuit, the target signal can be extracted and the SNR of the target signal is enhanced under different noise conditions. In some conditions, the adjustment of potential-well depth can induce different bifurcation features of the circuit, leading to the SNR enhancement. Finally, to demonstrate the feasibility of the TPWD bistable circuit in incipient fault diagnosis, it is employed to detect a shaft bending fault. Results show that the TPWD bistable circuit with the appropriate specification can significantly enhance the SNR of the target vibration signal of the shaft which is immersed in strong background noise. This is beneficial to the detection of the symptom of the bent shaft. Hence, the study proves that the proposed circuit can show a capability in real-time fault diagnosis without complicated programmable acquisition system.

BlockQuery: Toward forensically sound cryptocurrency investigation

Cryptocurrency transaction forensic examinations need to guarantee completeness, confidentiality, and information integrity. Our work presents BlockQuery as a proof of concept blockchain query system for Bitcoin. BlockQuery is capable of detecting transactions generated by Hierarchical Deterministic (HD) wallets that many publicly available tools cannot find due to failures in their address derivation methods. Moreover, BlockQuery does not use third party servers as data providers and operates on a local copy of the blockchain to prevent information disclosure. Compared to other Bitcoin query tools, BlockQuery was designed from a forensic standpoint and meets all four of the defined querying criteria of being open source, confidential, automatically converting key representations, and allowing the manual adjustment of derivation depth.

The Adjustable Grooved Feed Extruder

Abstract Grooved feed extruders have been around since about the 1960s. These extruders offer considerable advantages over conventional extruders, such as higher throughput, better stability, and the ability to process very high molecular weight polymers. There are some important disadvantages as well, for instance, higher motor load, wear is more likely, high pressures in the grooved region, and the screw design has to be adapted. The disadvantages of the grooved feed extruder disappear when the grooved feed extruder is made with a mechanism that allows adjustment of the groove depth. This paper will report on the development of grooved feed extruders that incorporate an adjustment mechanism that allows the depth of the grooves to be changed, during actual operation, from zero to full depth. Operational data from actual extrusion experiments are presented.

Time-dependent response of the overturning circulation and pycnocline depth to Southern Ocean surface wind stress changes

Abstract Changes in the Southern Ocean (SO) surface wind stress influence both the meridional overturning circulation (MOC) and stratification not only in the SO but in the global oceans, which can take multiple millennia to fully equilibrate. We use a hierarchy of models to investigate the time-dependent response of the MOC and low-latitude pycnocline depth (which quantifies the stratification) to SO wind stress changes: a two-layer analytical theory, a multi-column model (PyMOC), and an idealized general circulation model (GCM). We find that in both the GCM and PyMOC, the MOC has a multi-decadal adjustment timescale while the pycnocline depth has a multi-centennial timescale. The two-layer theory instead predicts the MOC and pycnocline depth to adjust on the same, multi-decadal timescale. We argue that this discrepancy arises because the pycnocline depth depends on the bulk stratification, while the MOC amplitude is sensitive mostly to isopycnals within the overturning cell. We can reconcile the discrepancy by interpreting the “pycnocline depth” in the theory as the depth of a specific isopycnal near the maximum of the MOC. We also find that SO stationary eddies respond very quickly to a sudden wind stress change, compensating for most of the change in the Ekman-driven MOC. This effect is missing in the theory, where the eddy-induced MOC only follows the adjustment of the pycnocline depth. Our results emphasize the importance of depth-dependence in the oceans’ transient response to changes in surface boundary conditions, and the distinct role played by stationary eddies in the SO.

耕深自动监测控制深松机深松单体设计与试验

Aiming at solving problems that the variation of tillage depth between rows and within rows caused by the surface undulation was great, the lateral stability of tillage depth obtained by the method of adjusting at the three-point suspension was poor, and lack of subsoilers with the function of accurate detection and adjustment of single row tillage depth, a method of independent control of single row tillage depth based on ultrasonic sensor detection and hydraulic adjustment was proposed. And the tillage depth monitoring and control subsoiling assembly and the subsoiler equipped with subsoiling assemblies were designed. The key structural parameters of the hydraulic cylinder and the model of the three-position four-way magnetic exchange valve were determined. The subsoiling quality and performance comparison tests were conducted, and the results showed that the mean value of the variable coefficient of soil hardness, looseness of soil and coefficient of soil disturbance were 52.23%, 32.55% and 62.15%, respectively, and the stability coefficient of tillage depth was 92.43%, which all met the subsoiling operation requirements. The standard deviation of tillage depth belonged to the method of independent adjustment of single row and unified adjustment of each row were 38.315mm and 51.521mm, respectively. The subsoiler equipped with tillage depth monitoring and control subsoiling assemblies designed in this paper was capable of significantly improving the stability of tillage depth between rows and within rows.

Use of GlideScope in Patients Undergoing NIM Thyroidectomy.

Thyroidectomy and parathyroidectomy using the nerve integrity monitor (NIM) require proper placement of the endotracheal tube with electrodes aligned correctly within the larynx. The purpose of this study is to determine the percentage of patients who require positional adjustments of the endotracheal tube prior to beginning surgery and to understand the value of using the GlideScope to assure proper NIM tube placement within the larynx. This prospective study examines operative data from 297 patients who underwent NIM thyroidectomy and parathyroidectomy. After routine orotracheal intubation by an anesthesiologist and positioning of the patient for surgery, a GlideScope was used to check the position of the tube in 2 planes: depth of tube placement and rotation of the tube within the larynx assuring proper placement of the electromyogram electrodes within the glottis. Tube adjustment was required for 66.5% of patients. In 48.1% of cases, tube retraction or advancement to a proper depth was needed. Tube rotation was required for 30.1% of patients, and 11.8% of patients required both adjustment of tube depth and tube rotation to properly align electrodes. After the anesthesiologist places the NIM endotracheal tube, and the patient is positioned for surgery, additional tube adjustment is often needed prior to the start of surgery. The GlideScope is readily available in the operating suite, its use adds little time to the procedure, and assures proper NIM tube placement. The use of the GlideScope is recommended.

In vivo localization of chronically implanted electrodes and optic fibers in mice

Electrophysiology provides a direct readout of neuronal activity at a temporal precision only limited by the sampling rate. However, interrogating deep brain structures, implanting multiple targets or aiming at unusual angles still poses significant challenges for operators, and errors are only discovered by post-hoc histological reconstruction. Here, we propose a method combining the high-resolution information about bone landmarks provided by micro-CT scanning with the soft tissue contrast of the MRI, which allowed us to precisely localize electrodes and optic fibers in mice in vivo. This enables arbitrating the success of implantation directly after surgery with a precision comparable to gold standard histology. Adjustment of the recording depth with micro-drives or early termination of unsuccessful experiments saves many working hours, and fast 3-dimensional feedback helps surgeons avoid systematic errors. Increased aiming precision enables more precise targeting of small or deep brain nuclei and multiple targeting of specific cortical or hippocampal layers.

Periprocedural Predictors of New-Onset Conduction Abnormalities After Transcatheter Aortic Valve Replacement.

New-onset conduction abnormalities (CAs) following transcatheter aortic valve replacement (TAVR) are associated with hospital rehospitalization and long-term mortality, but available predictors are sparse. This study sought to determine clinical predictors of new-onset left bundle branch block (LBBB) and new permanent pacemaker (PPM) implantation in patients undergoing TAVR. We enrolled 290 patients who received SAPIEN 3 (Edwards Lifesciences, Irvine, CA, USA; n=217) or Evolut R (Medtronic, Minneapolis, MN, USA; n=73) from a prospective registry at Nouvel Hôpital Civil, Strasbourg, France between September 2014 and February 2018. Of 242 patients without pre-existing LBBB, 114 (47%) experienced new-onset LBBB and/or new PPM implantation. A difference between membranous septal length and implantation depth (∆MSID) was the only predictor of CAs for both types of valves. In the multivariate analysis, PR interval and ∆MSID remained as sole predictors of CAs. The risk for adverse clinical events, including all-cause death, myocardial infarction, stroke, and heart failure hospitalization, was higher for patients with CAs as compared with patients without CAs (hazard ratio: 2.10; 95% confidence interval: 1.26 to 3.57; P=0.004). Computed tomography assessment of membranous septal anatomy and implantation depth predicted CAs after TAVR with new-generation valves. Future studies are required to identify whether adjustment of the implantation depth can reduce the risk of CAs and adverse clinical outcomes.

Stable Immune Response Induced by Intradermal DNA Vaccination by a Novel Needleless Pyro-Drive Jet Injector

DNA vaccination can be applied to the treatment of various infectious diseases and cancers; however, technical difficulties have hindered the development of an effective delivery method. The efficacy of a DNA vaccine depends on optimal antigen expression by the injected plasmid DNA. The pyro-drive jet injector (PJI) is a novel system that allows for adjustment of injection depth and may, thus, provide a targeted delivery approach for various therapeutic or preventative compounds. Herein, we investigated its potential for use in delivering DNA vaccines. This study evaluated the optimal ignition powder dosage, as well as its delivery effectiveness in both rat and mouse models, while comparing the results of the PJI with that of a needle syringe delivery system. We found that the PJI effectively delivered plasmid DNA to intradermal regions in both rats and mice. Further, it efficiently transfected plasmid DNA directly into the nuclei, resulting in higher protein expression than that achieved via needle syringe injection. Moreover, results from animal ovalbumin (OVA) antigen induction models revealed that animals receiving OVA expression plasmids (pOVA) via PJI exhibited dose-dependent (10 μg, 60 μg, and 120 μg) production of anti-OVA antibodies; while only low titers (< 1/100) of OVA antibodies were detected when 120 μg of pOVA was injected via needle syringe. Thus, PJI is an effective, novel method for delivery of plasmid DNA into epidermal and dermal cells suggesting its promise as a tool for DNA vaccination.

Study on flexible two-axis roll-bending process for component with non-circular section

Two-axis roll-bending technology, with the advantages of small curvature radius, short straight section and high efficiency, is widely used in fields of aerospace and automobile. By adjusting indentation depth in two-axis roll-bending process, different curvature radius of circular and elliptic component can be formed. Roll-bending experiments and numerical simulations for component with circular and elliptic section are conducted. The results show that the forming curvature radius of circular component and its deviation both decrease with ascending indentation depth. The relationship between forming curvature radius and indentation depth is polynomial fitted. On this basis, ellipse parameter equation is established and different curvature radius at different position of the ellipse is achieved by adjustment of indentation depth. The relationship between indentation depth and forming time is obtained for elliptic component. Elliptic components with different sizes are formed. The stress distribution is uniform after roll-bending process and it increases with ascending indentation depth.

Surgical Stereo X-Ray Navigation

Hardware and software for surgical instrument navigation using stereo X-ray imaging were developed. The developed surgical stereo X-ray navigation system provides 3D imaging in the process of surgery or during diagnostic examination of deep-lying abnormal foci or structural abnormalities of organs and tissues. Application of the developed system makes it possible to reduce considerably the duration of surgery. The obtained 3D X-ray images are automatically processed to provide accurate real-time guidance of the medical instrument (i.e., adjustment of the penetration depth, position, and orientation of the instrument). The developed technique of stereo X-ray navigation can be used for purposes of upgrading medical X-ray equipment, such as C-arch (Arcoscope) surgical X-ray devices.

Deployable cylindrical phased-array applicator mimicking a concentric-ring configuration for minimally-invasive delivery of therapeutic ultrasound

A novel design for a deployable catheter-based ultrasound applicator for endoluminal and laparoscopic intervention is introduced. By combining a 1D cylindrical ring phased array with an expandable paraboloid or conical-shaped balloon-based reflector, the applicator can be controllably collapsed for compact delivery and deployed to mimic a forward-firing larger diameter concentric ring array with tight focusing and electronic steering capabilities in depth. Comprehensive acoustic and biothermal parametric studies were employed to characterize the capabilities of the applicator design as a function of transducer dimensions, phased array configuration, and balloon reflector geometry. Modeling results indicate that practical balloon sizes (43–57 mm expanded diameter), transducer array configurations (e.g. 1.5 MHz, 10 mm OD × 20 mm length, 8 or 16 array elements), and sonication durations (30 s) are capable of producing spatially-localized acoustic intensity focal patterns and ablative thermal lesions (width: 2.8–4.8 mm; length: 5.3–40.1 mm) in generalized soft tissue across a 5–100 mm depth range. Larger focal intensity gain magnitudes and narrower focal dimensions are attainable using paraboloid-shaped balloon reflectors with natural geometric focal depths of 25–55 mm, whereas conical-shaped reflectors (angled 45–55°) produce broader foci and extend electronic steering range in depth. A proof-of-concept phased array applicator assembly was fabricated and characterized using hydrophone and radiation force balance measurements and demonstrated good agreement with simulation. The results of this study suggest that combining small diameter cylindrical phased arrays with expandable balloon reflectors can enhance minimally invasive ultrasound-based intervention by augmenting achievable focal gains and penetration depths with dynamic adjustment of treatment depth.

The Exeter Short Revision Stem for Cement-in-Cement Femoral Revision: A Five to Twelve Year Review

BackgroundCement-in-cement femoral revision is a proven technique in revision total hip arthroplasty, with excellent results reported using standard-sized Exeter stems. The Exeter 44/00/125 short revision stem was introduced in 2004 to facilitate cement-in-cement revision. The stem is 25-mm shorter and has a slimmer body than standard stems to facilitate adjustment of depth of insertion and stem version. It is not known if this change in stem size affects its long-term performance. We therefore reviewed the outcome of all Exeter short revision stems used for cement-in-cement revision in our unit, with a minimum of 5 years of follow-up. MethodOne hundred sixty-six cases were performed between 2004 and 2010. Mean follow-up of surviving patients was 8.1 years (range 5.0-11.7). The fate of all 166 hips were known and included in the survival analysis. ResultsMedian clinical scores improved significantly. Sixteen hips required re-revision (infection 6, loose cup 3, periprosthetic fracture 3, instability 2, stem fracture with chronic infection 1, and pain 1). Kaplan-Meier survival analysis at 10 years revealed 100% survival for aseptic stem loosening, 96.8% survival for stem failure, and 88.9% survival for all causes. ConclusionThe Exeter short revision stem performed as well as standard length stems for cement-in-cement revision in this the largest and longest review of their use. Larger registry-based studies may provide additional information on the performance of this stem.

Awake Testing during Deep Brain Stimulation Surgery Predicts Postoperative Stimulation Side Effect Thresholds.

Despite substantial experience with deep brain stimulation for movement disorders and recent interest in electrode targeting under general anesthesia, little is known about whether awake macrostimulation during electrode targeting predicts postoperative side effects from stimulation. We hypothesized that intraoperative awake macrostimulation with the newly implanted DBS lead predicts dose-limiting side effects during device activation in clinic. We reviewed 384 electrode implants for movement disorders, characterized the presence or absence of stimulus amplitude thresholds for dose-limiting DBS side effects during surgery, and measured their predictive value for side effects during device activation in clinic with odds ratios ±95% confidence intervals. We also estimated associations between voltage thresholds for side effects within participants. Intraoperative clinical response to macrostimulation led to adjustments in DBS electrode position during surgery in 37.5% of cases (31.0% adjustment of lead depth, 18.2% new trajectory, or 11.7% both). Within and across targets and disease states, dose-limiting stimulation side effects from the final electrode position in surgery predict postoperative side effects, and side effect thresholds in clinic occur at lower stimulus amplitudes versus those encountered in surgery. In conclusion, awake clinical testing during DBS targeting impacts surgical decision-making and predicts dose-limiting side effects during subsequent device activation.

Potential limitations of behavioral plasticity and the role of egg relocation in climate change mitigation for a thermally sensitive endangered species.

Anthropogenic climate change is widely considered a major threat to global biodiversity, such that the ability of a species to adapt will determine its likelihood of survival. Egg‐burying reptiles that exhibit temperature‐dependent sex determination, such as critically endangered hawksbill turtles (Eretmochelys imbricata), are particularly vulnerable to changes in thermal regimes because nest temperatures affect offspring sex, fitness, and survival. It is unclear whether hawksbills possess sufficient behavioral plasticity of nesting traits (i.e., redistribution of nesting range, shift in nesting phenology, changes in nest‐site selection, and adjustment of nest depth) to persist within their climatic niche or whether accelerated changes in thermal conditions of nesting beaches will outpace phenotypic adaption and require human intervention. For these reasons, we estimated sex ratios and physical condition of hatchling hawksbills under natural and manipulated conditions and generated and analyzed thermal profiles of hawksbill nest environments within highly threatened mangrove ecosystems at Bahía de Jiquilisco, El Salvador, and Estero Padre Ramos, Nicaragua. Hawksbill clutches protected in situ at both sites incubated at higher temperatures, yielded lower hatching success, produced a higher percentage of female hatchlings, and produced less fit offspring than clutches relocated to hatcheries. We detected cooler sand temperatures in woody vegetation (i.e., coastal forest and small‐scale plantations of fruit trees) and hatcheries than in other monitored nest environments, with higher temperatures at the deeper depth. Our findings indicate that mangrove ecosystems present a number of biophysical (e.g., insular nesting beaches and shallow water table) and human‐induced (e.g., physical barriers and deforestation) constraints that, when coupled with the unique life history of hawksbills in this region, may limit behavioral compensatory responses by the species to projected temperature increases at nesting beaches. We contend that egg relocation can contribute significantly to recovery efforts in a changing climate under appropriate circumstances.
