title: How to Prevent Flight Hardware Failures During Shock Qualification Test?

description: In the last few years, there have been several recorded JPL hardware failures during shock qualification tests. These failures raised concerns amongst project management, cognizant engineers, analysts, and others stake holders. These concerns were wrongfully attributed by some to potential over-test using JPL’s tunable beam shock simulation system (TBSS), a conclusion that was not shared by experienced subject matter experts. All the failures from cases examined were traced to issues unrelated to the TBSS. The prime failure mode was traced, in most cases, to excessive sustained structural excitations occurring in mid- to high-frequency shock regions. Other issues were related to overly conservative requirements (in particular specification of the knee frequencies), over-test by test conductors, possible fixture coupling, and design deficiencies. In this paper, root causes of a few flight hardware failures are discussed in detail. A series of recommendations are provided to better prepare for shock tests and to help minimize or even eliminate flight hardware failures.

title: Predicting the Dominant Formation Mechanism of Multi-Planetary Systems

description: Most, if not all, sun-like stars host one or more planets, making multi-planetary systems commonplacein our galaxy. We utilize hundreds of multi-planet simulations to explore the origin of such systems,focusing on their orbital architecture. The first set of simulations assumes in-situ assembly of planetaryembryos, while the second explores planetary migration. After applying observational biases to thesimulations, we compare them to 250+ observed multi-planetary systems, including 13 systems withplanets in the habitable zone. For all of the systems, we calculate two of the so-called statisticalmeasures: the mass concentration (Sc) and orbital spacing (Ss). After analytic and empirical analyses,we find that the measures are related to first-order with a power law: Sc ∼ Sβs. The in-situ systemsexhibit steeper power-law relations relative to the migration systems. We show that different formationscenarios cover different regions in the Ss − Sc diagram with some overlap. Furthermore, we discoverthat observed systems with Ss &lt; 30 are likely dominated by the migration scenario, while those withSs ≥ 30 are likely dominated by the in-situ scenario. We apply these criteria to determine thata majority (62%) of observed multi-planetary systems formed via migration, whereas most systemswith currently observed habitable planets formed via in-situ assembly. This work provides methodsof leveraging the statistical measures (Ss and Sc) to disentangle the formation history of observedmulti-planetary systems based on their present-day architectures.

title: Counts of breeding seabirds and herons at Ashmore Reef and Cartier Island off the Kimberley coast, Australia (1949-2014)

description: Ashmore Reef is situated on the edge of Sahul Shelf, off the Kimberley coast, Australia. Surveys in 2010 indicate the three small islands within Ashmore Reef support approximately 100,000 breeding seabirds of 16 species and four heron species on an annual basis. That such a diversity and abundance of tropical seabirds utilize a total land area of just 55 ha for breeding purposes is exceptional in an international context Cartier Island and the surrounding reef is an isolated Australian Territory situated in the Timor Sea. This dataset summarises all known ornithological records from the Island and detail the results of twice-annual bird surveys conducted within the Cartier Island Australian Marine Park between 2010 and 2014. See cited papers for data and additional observations.

title: A Cryogenic CO2 Scrubber with an Integrated Switchable Heat Pipe

description: Human missions to explore Moon, Mars, and beyond will require reliable, compact air revitalization systems. Using a cryogenic separation system to deposit CO2 from the processed air steam and thus remove it from the air flow is a very attractive approach for long-duration missions because it eliminates the need for consumable adsorption systems. The required cryocooling power to achieve the target CO2 removal rate for a spacecraft with four crewmembers is quite high, more than tens of Watts below 125 K. A critical need for this technology is a cryogenic CO2 scrubber with an integrated heat transport mechanism to efficiently transfer heat to a remotely located active or passive cooler during the collection phase, and to thermally disconnect from the cooler during the regeneration phase to eliminate the need for two separate cryocoolers. To meet this need, we are developing a CO2 scrubber with a built-in cryogenic liquid trap switchable heat pipe to connect the scrubber with a cooler. The scrubber has enhanced heat transfer surfaces to collect CO2 snow. The enhanced surfaces are directly cooled by evaporation of heat pipe working fluid, instead of relying on thermal conduction cooling to minimize temperature gradients on the enhanced surfaces. The enhanced surfaces also have features to promote a uniform air flow and minimize impact of channel clogging as CO2 accumulates. The design of the scrubber and switchable heat pipe is built on JPL’s experience in additive manufacturing of two-phase thermal devices with porous media. This paper discusses the design of the scrubber and the switchable heat pipe, as well as the test setup and preliminary test data for the proof-of-concept switchable heat pipe.

title: Shock Model and Test Correlation for Structural Response Prediction

description: When defining hardware shock environments, it is typical to assume a reduction of shock levels through structural joints – nominally, a 30% reduction per joint up to a maximum of three joints. However, review of shock test data from a flight-like test article demonstrates that attenuation across interfaces is not always realized. Across a single joint, significant amplification is observed at various locations on the composite shell of the test article throughout the entire frequency range, with maximum amplification of ~12dB. Responses across a second joint still shows low frequency amplification coupled with mid- to high-frequency attenuation. While empirical scaling of shock inputs may be appropriate for most applications, its failure to account for potential amplification may result in an underestimate of a hardware’s shock environment. The effect of mass loading on hardware responses was also investigated, which demonstrated the complexities of mass attenuation, including frequency and location dependencies. This contrasts with the Barrett Method for mass scaling of vibroacoustic responses. An analytical framework for deriving shock environments and accurately predicting the degree of attentions and amplifications where structural modes are from system-level specifications would be beneficial to qualifying hardware for flight shock environments.

title: The High Energy X-ray Probe (HEX-P): Constraining Supermassive Black Hole Growth with Population Spin Measurements

description: Constraining the primary growth channel of supermassive black holes (SMBH) remains one the most actively debated questions in the context of cosmological structure formation. Owing to the expected connection between SMBH spin parameter evolution and the accretion and merger history of individual black holes, population spin measurements offer a rare observational window into the SMBH cosmic growth. As of today, the most common method for estimating SMBH spin relies on modeling the relativistically broaden atomic profiles in the reflection spectrum observed in X-rays. In this paper, we study the observational requirements needed to confidently distinguish between the primary SMBH growth channels, based on their distinct spin-mass distributions predicted by the Horizon-AGN cosmological simulation. In doing so, we characterize outstanding limitations associated with the existing measurements and discuss the landscape of future observational campaigns, which can be planned and executed with future X-ray observatories. We focus our attention on the High-Energy X-ray Probe (HEX-P), a concept probe-class mission aimed to serve the high-energy community in the 2030s.

title: Feasibility of non-intubated anesthesia and regional block for thoracoscopic surgery under spontaneous respiration: a prospective cohort study

description: Data about the feasibility and safety of thoracoscopic surgery under non-intubated anesthesia and regional block are limited. In this prospective study, 57 consecutive patients scheduled for thoracoscopic surgery were enrolled. Patients were sedated with dexmedetomidine and anesthetized with propofol and remifentanil. Ropivacaine was used for intercostal nerve and paravertebral block. Lidocaine was used for vagal block. The primary outcomes were mean arterial pressure (MAP), heart rate (HR), oxygen saturation, and end-tidal carbon dioxide partial pressure (ETCO2) at T0 (pre-anesthesia), T1 (immediately after laryngeal mask/nasopharyngeal airway placement), T2 (immediately after skin incision), T3 (10 min after opening the chest), T4 (end of surgery), and T5 (immediately after laryngeal mask/nasopharyngeal airway removal). One patient required conversion to intubation, 15 developed intraoperative hypotension, and two had hypoxemia. MAP at T0 and T5 was higher than at T1–T4; MAP at T3 was lower (P&lt;0.05 vs other time points). HR at T0 and T5 was higher (P&lt;0.05 vs other time points). ETCO2 at T2 and T3 was higher (P&lt;0.05 vs other time points). Arterial pH, PCO2, and lactic acid at T1 differed from values at T0 and T2 (P&lt;0.05). The Quality of Recovery-15 (QoR-15) score at 24 h was lower (P&lt;0.05). One patient experienced dysphoria during recovery. Thoracoscopic surgery with regional block under direct thoracoscopic vision is a feasible and safe alternative to conventional surgery under general anesthesia, intubation, and one-lung ventilation.

title: Effect of fasudil on experimental autoimmune neuritis and its mechanisms of action

description: This study aimed to investigate the therapeutic effect of fasudil on treating experimental autoimmune neuritis (EAN). Twenty-four EAN mice were randomly assigned to fasudil treatment (Fasudil group) or saline treatment (EAN model group) for 28 days. Clinical symptom score was evaluated every other day; inflammatory cell infiltration, demyelination, anti-myelin basic protein (MBP), inflammatory cytokines, inducible nitric oxide synthase (iNOS), and arginase-1 were detected in sciatic nerves at day 28. Th1, Th2, Th17, and Tregs proportions in splenocytes were detected at day 28. Clinical symptom score was found to be attenuated in the Fasudil group compared to the EAN model group from day 12 to day 28. Sciatic nerve inflammatory cell counts by HE staining and demyelination by luxol fast blue staining were both reduced, while MBP was increased in the Fasudil group compared to the EAN model group at day 28. Interferon γ (IFN-γ) and interleukin (IL)-17 were reduced, while IL-4 and IL-10 were elevated in the Fasudil group at day 28. Sciatic nerve M1 macrophages marker iNOS was decreased while M2 macrophages marker arginase-1 was increased in the Fasudil group at day 28. CD4+IFN-γ+ (Th1) and CD4+IL-17+ (Th17) cell proportions were both decreased, CD4+IL-4+ (Th2) cell proportion was similar, while CD25+FOXP3+ (Treg) cell proportion in splenocytes was increased in the Fasudil group. In summary, fasudil presented a good therapeutic effect for treating EAN by attenuating Th1/Th17 cells and promoting Tregs activation as well as M2 macrophages polarization.

title: Use of flash glucose-sensing technology in patients with type 2 diabetes treated with liraglutide combined with CSII: a pilot study

description: Glycemic variability (GV) may be linked to the development of diabetic complications by inducing inflammation, oxidative stress, and endothelial dysfunction. Flash glucose monitoring (FGM) provides a novel method of continuously monitoring interstitial glucose levels for up to 14 days. This study randomly assigned poorly controlled type 2 diabetes mellitus patients treated with metformin and multiple daily injections of insulin (n=60) to either continuous subcutaneous insulin infusion (CSII) treatment or CSII in combination with liraglutide (CSII+Lira) treatment for 14 days during hospitalization. GV was assessed using a FGM system; weight and cardiometabolic biomarkers were also evaluated. The coefficient of variation was significantly reduced in the CSII+Lira group (P&lt;0.001), while no significant change was observed in the CSII group. The changes differed significantly between the two groups in mean amplitude of glycemic excursions (P=0.004), standard deviation (P=0.006), and the percentage of time in the target range (4–10 mmol/L, P=0.005 and &gt;10 mmol/L, P=0.028). The changes in mean of daily differences, interquartile range, and percentage of time in hypoglycemia (&lt;3.3 mmol/L) and hyperglycemia (&gt;13.9 mmol/L) identified by FGM showed no difference. Treatment with liraglutide increased serum adiponectin [33.5 (3.5, 47.7) pg/mL, P=0.003] and heme oxygenase-1 levels [0.4 (–0.0, 1.8) ng/mL, P=0.001] and reduced serum leptin levels [–2.8 (3.9) pg/mL, P&lt;0.001]. Adding the glucagon-like peptide-1 analog liraglutide improved GV, weight, and some cardiometabolic risk markers. The FGM system is, therefore, shown to be a novel and useful method for glucose monitoring.

title: Total Panax notoginseng saponin inhibits balloon injury-induced neointimal hyperplasia in rat carotid artery models by suppressing pERK/p38 MAPK pathways

description: Total Panax notoginseng saponin (TPNS) is the main bioactivity compound derived from the roots and rhizomes of Panax notoginseng (Burk.) F.H. Chen. The aim of this study was to investigate the effectiveness of TPNS in treating vascular neointimal hyperplasia in rats and its mechanisms. Male Sprague-Dawley rats were randomly divided into five groups, sham (control), injury, and low, medium, and high dose TPNS (5, 10, and 20 mg/kg). An in vivo 2F Fogarty balloon-induced carotid artery injury model was established in rats. TPNS significantly and dose-dependently reduced balloon injury-induced neointimal area (NIA) (P&lt;0.001, for all doses) and NIA/media area (MA) (P&lt;0.030, for all doses) in the carotid artery of rats, and PCNA expression (P&lt;0.001, all). The mRNA expression of smooth muscle (SM) α-actin was significantly increased in all TPNS groups (P&lt;0.005, for all doses) and the protein expression was significantly increased in the medium (P=0.006) and high dose TPNS (P=0.002) groups compared to the injury group. All the TPNS doses significantly decreased the mRNA expression of c-fos (P&lt;0.001). The medium and high dose TPNS groups significantly suppressed the upregulation of pERK1/2 protein in the NIA (P&lt;0.025) and MA (P&lt;0.004). TPNS dose-dependently inhibited balloon injury-induced activation of pERK/p38MAPK signaling in the carotid artery. TPNS could be a promising agent in inhibiting cell proliferation following vascular injuries.
