Published: January 2021

Spirulina platensis merupakan mikroalga hijau biru yang memiliki kandungan protein tinggi, sehingga sering dimanfaatkan sebagai pangan fungsional. Penerapan Spirulina platensis sebagai pangan fungsional sering mengalami kendala karena kandungan senyawa volatile penyebab aroma kurang sedap pada mikroalaga ini. Intervensi O. bacillicum pada S. platensis dapat mengurangi aroma kurang sedap yang ditimbulkan. Mikroenkapsulasi dilakukan untuk menjaga stabilitas nutrisi serta serta menahan aroma saat dikonsumsi. Tujuan penelitian ini adalah untuk menentukan pengaruh intervensi O. bacillicum terhadap kandungan protein S. platensis, nilai pH dan tingkat kesukaan pada serbuk dan mikrokapsul S. platensis. Spirulina sebagai sampel kontrol (SP), intervensi O. bacillicum yang dikeringakan (DSB), dan yang dilakukan mikroenkapsulasi (MSB). Hasil penelitian menunjukan bahwa intervensi O. bacillicum pada S. platensis serta dilakukan mikroenkapsulasi berpengaruh (P < 0,05) terhadap kadar protein, nilai pH dan uji hedonik. meningkatkan nilai pH, menurunkan kadar protein 19,87% pada sampel DSB dan menurun drastis pada sampel MSB. Asam amino mengalami penurunan kecuali asam aspartat dan arginin. Semakin tinggi nilai pH dari perlakuan intervensi tersebut semakin rendah kadar proteinnya. Intervensi O. bacillicum dapat meningkatkan skala hedonik pada S. platensis. Sampel DSB memberikan nilai terbaik pada aroma, sedangkan sampel MSB memberikan nilai terbaik pada warna yang dihasilkan. Oleh karena itu intervensi O. bacillicum pada S. platensis menjadi solusi dalam mengurangi aroma tidak sedap pada S. platensis.
Near-Field Strong Ground Motions from GPS-Derived Velocities for 2020 Intermountain Western United States Earthquakes
Authors: Crowell Brendan W. 
Published: January 2021

Abstract
In early 2020, four moderate sized earthquakes occurred in the Intermountain region of the western United States, two M 6.5 events in Challis, Idaho, and Monte Cristo Range, Nevada; an M 5.7 in Magna, Utah, within the Salt Lake City metropolitan area; and an M 5.8 in the Owens Valley of California. Although the Magna and Owens Valley earthquakes were well recorded in the near field with an array of seismic instrumentation, the Challis and Monte Cristo events were not densely recorded. All of the events, however, have reasonable coverage with high rate Global Positioning System (GPS) stations in the near field. Here, I report on strong-motion observations recorded at 19 regional GPS stations at 5 Hz. I compare these observations with seismic recordings where available and ShakeMap estimations of peak ground velocity to find good agreement with a natural-log residual of ±0.5. Furthermore, I compute the correlation between collocated stations and show a strong positive correlation &gt;0.65. This study highlights the utility of high-rate GPS velocity observations to strong-motion seismology.

Published: January 2021

The thermal conductivity (K) of Jezersko H4 meteorite was predicted by various models of rocks, using literature data on the chemical composition, porosity (P), and by relationships between thermal conductivity and porosity, and between thermal conductivity and thermal diffusivity (D). The results confirm that the porosity of the chondrite and air pressure significantly affect thermal conductivity. The thermal conductivity of the chondrite skeleton/matrix predicted by the modal composition of the meteorite and by the geometric mean model is equal to 4.35 W m−1 K−1, and by arithmetic and harmonic mean models: 4.9 W m−1 K−1at 300 K. Bulk thermal conductivity of the meteorite predicted by the geometric mean model is equal to 2.6 W m-1 K-1 for air pressure of 1 atm, and 1.0 W m−1 K−1in vacuum at 300 K. The Hashin–Shtrikman model predicts the values: 2.4 and 1.9 W m−1 K−1, the Clausius–Mossotti model: 2.2 and 1.9 W m-1 K-1, and the mean of two-layer models: 2.1 and 2.0 W m−1 K−1 at 300 K, for air pressure of 1 atm, and in vacuum, respectively. The relationships between thermal conductivity and porosity based on experimental data for ordinary chondrites indicate a mean K value for bulk thermal conductivity of the Jezersko meteorite in vacuum: 1.18 W m−1 K−1, and between thermal conductivity and thermal diffusivity the mean value: 1.12 W m−1 K−1at 200–300 K. The mean value for all predictions for bulk thermal conductivity of the meteorite for air at 1 atm is equal to 2.45 ± 0.30 W m−1 K−1 (range: 2.0–2.9 W m−1 K−1) at 300 K, and in vacuum: 1.40 ± 0.40 W m−1 K−1 (range: 0.95–2.0 W m−1 K−1) at 200–300 K. Predicted values of bulk thermal conductivity of the Jezersko meteorite, for air and in vacuum, are in the range of values recently reported by Soini et al. (2020) for the H4 group of chondrites: 2.8 ± 0.6 W m−1 K−1, mean K for air at 1 atm, and 1.9 ± 1.0 W m−1 K−1 mean K value in vacuum at 200–300 K.

The proper cleaning of the annular space before cementing is one of the most important factors affecting the proper sealing of the casing column. Inadequate or incomplete removal of the mud cake or residues of the mud may result in the formation of uncontrolled gas outflows (migration or exhalation) at the contact of the cement sheath with the rock formation and with the surface of run-down casing. It is related to the lack of compatibility in the contact of the mud and the cement. Additionally, the lack of proper cleaning of the annular space will reduce the adhesion value of the cement sheath to the contact surface. The result of the above may be the lack of adequate stabilization of the column of pipes due to its weakened connection in the lower part with the wall, and in the upper part with the previous column of larger diameter pipes. Therefore, to improve both the tightness of the borehole as well as the quality of the cementation condition, laboratory tests of the efficiency of cleaning the annular space are carried out by measuring the efficiency of washing mud removal. So far, measuring the efficiency of mud removal or the effect of washing utilization have been done using a rotary viscometer. During the test, a mud cake is produced on the rotor surface and then removed with washing liquid. Recently, the Oil and Gas Institute – National Research Institute developed a new method for measuring the efficiency of drilling mud removal by using a newly developed drilling fluid flow simulator (Patent P.423842). The device enables the simulation of the drilling fluid flow (drilling fluid, washing fluid, spacer) in the simulated annular space. It is possible to select the parameters of the flow (delivery rate) and the contact time of the liquid with the tested surface. Due to the different measurement principles during the tests with the viscometer and the simulator, it was decided to conduct a comparison and determine the degree of convergence of the discussed methods. The same rinsing liquids were tested to remove the same type of mud, but using different measurement methods. The obtained values of mud removal efficiency were subjected to the correlation analysis, which made it possible to compare the results of the analyzed measurement methods.

Update
This article was updated on May 13, 2021, because of a previous error. On page e36(1), the title that had read “Flexor Tendon Injury and Repair. The Influence of Synovial Environment on the Early Healing Response in a Canine Mode” now reads “Flexor Tendon Injury and Repair. The Influence of Synovial Environment on the Early Healing Response in a Canine Model.”
An erratum has been published: J Bone Joint Surg Am. 2021 June 16;103(12):e50

Background:
Environmental conditions strongly influence the healing capacity of connective tissues. Well-vascularized extrasynovial tendons typically undergo a robust wound-healing process following transection and repair. In contrast, avascular intrasynovial tendons do not mount an effective repair response. The current study tests the hypothesis that flexor tendons, as a function of their synovial environment, exhibit unique inflammatory, angiogenic, and metabolic responses to injury and repair.

Methods:
Flexor tendons present a distinct opportunity to test the study hypothesis, as they have proximal regions that are extrasynovial and distal regions that are intrasynovial. In an internally controlled study design, the second and fifth forepaw flexor tendons were transected and repaired in either the extrasynovial or the intrasynovial anatomical region. Histological, gene expression, and proteomics analyses were performed at 3 and 7 days to define the early biological events that drive synovial environment-dependent healing responses.

Results:
Uninjured intrasynovial tendons were avascular, contained high levels of proteoglycans, and expressed inflammatory factors, complement proteins, and glycolytic enzymes. In contrast, extrasynovial tendons were well vascularized, contained low levels of proteoglycans, and were enriched in inflammation inhibitors and oxidative phosphorylation enzymes. The response to injury and repair was markedly different between the 2 tendon regions. Extrasynovial tendons displayed a robust and rapid neovascularization response, increased expression levels of complement proteins, and an acute shift in metabolism to glycolysis, whereas intrasynovial tendons showed minimal vascularity and muted inflammatory and metabolic responses.

Conclusions:
The regional molecular profiles of intact and healing flexor tendons revealed extensive early differences in innate immune response, metabolism, vascularization, and expression of extracellular matrix as a function of the synovial environment. These differences reveal mechanisms through which extrasynovial tendons heal more effectively than do intrasynovial tendons.

Clinical Relevance:
To improve outcomes after operative repair, future treatment strategies should promote features of extrasynovial healing, such as enhanced vascularization and modulation of the complement system and/or glucose metabolism.
Experimental Verification of General Validity of Non-force Interaction Formula
Authors: Teslia Iurii 
Published: January 2021

Abstract
In the present work, the physical and mathematical principles of the non-force interaction theory are presented. It is shown that in the basis of this theory there are computer experiments within which there was simulated movement and interaction of material objects through the change of their hypothetical informational contents. The formulae of transformation of the hypothetical informational contents of material objects received from the information-probabilistic interpretation of mechanical movement were used in the experimental research to demonstrate that they also correspond to the processes of speech production in a human brain. The hypothesis, objective and tasks of the experimental research were defined. The methods and software tools were developed to conduct the experiments. To compare different results of the simulation of the processes in a human brain during speech production, there was a range of methods proposed to calculate the estimate of sequence of fragments of natural language texts including the methods based on linear approximation.
The conducted experiments have proved that the formulae received from information-probabilistic interpretation of mechanical movement reflect the processes of speech production. It is shown that the offered approach can successfully be used to create systems of reactive artificial intelligence machines. Experimental and, presented in this work, practical results constitute that the non-force (informational) interaction formulae are generally valid.

Abstract
Background: Tai Chi has been proved as an effective strategy to improve cognitive function while the mechanism remains unclear. This cross-sectional study aimed to compare the brain functional connection of prefrontal cortex (PFC), motor cortex (MC) and occipital cortex (OC) in middle-aged Tai Chi practitioners and Tai Chi-naïve controls. Methods: 18 Hong chuan Tai Chi practitioners (age:55.78±2.64y) and 22 demographically matched healthy Tai Chi-naïve controls (age:54.69±3.10y) were recruited in this study. Global cognition was measured by the Montreal Cognitive Assessment Scale (MoCA), and the functional connection between PFC, MC and OC in five frequency intervals (I, 0.6-2Hz; II, 0.145-0.6Hz; III, 0.052-0.145Hz; IV, 0.021-0.052Hz; V, 0.0095-0.021Hz) was analyzed by wavelet phase coherence (WPCO). The changes in cerebral oxygenation (Δ[HbO2]) were measured by functional near-infrared spectroscopy (fNIRS). Continuous recordings of NIRS signals were obtained from the left and right prefrontal cortex (PFC), motor cortex (MC) and occipital cortex (OC) in resting state. Results: Compared with age-matched Tai Chi-naïve controls, Hong chuan Tai Chi practitioners had better global cognition and showed higher functional connection levels between left and right PFC, MC, OC in intervals I, III, VI and V in resting state. Conclusion: This study showed that middle-aged Hong chuan Tai Chi practitioners had higher functional connection between PFC, MC and OC, as well as the coordination of left and right brain in resting state, which maybe the contributing factors to higher global cognition.

Abstract
Background: The study presents an analysis of selected psychomotor abilities of female handball players at different levels of experience. Methods: Studies were performed using Test2Drive computer tests. The following four tests were used to measure psychomotor fitness: Simple Reaction Time, Choice Reaction Time, Hand-Eye Coordination and Spatial Anticipation. The study covered a group of 118 female handball players (age: 19.6 ± 3.16),who play in the PGNiG Polish Women’s Superliga, Polish 1st and 2nd handball league, for the following positions: goalkeepers, centre players, pivot players and wing players. The study also included the body composition analysis and the aerobic capacity level with the use of the multistage 20 metre shuttle run test. In addition, the level of psychomotor abilities of female handball players has been analysed depending on their competition class (league), position on the court and dominant hand. Results: The analysis of the reaction time and movement time showed statistically significant differences between the results (SIRT MT, CHORT RT,HECOR MT) obtained by the female handball players from different competition classes. Additionally, on the basis of the linear Pearson correlation were determined statistically significant relationship between psychomotor abilities and elements of body composition or the aerobic capacity level. Conclusions: The analysis showed that the female players from Polish Women’s Superliga had the highest level of reaction time (SIRT, CHORT and SPANT tests). The study also revealed a significant impact of the body mass index and the percentage of fat content on the movement time (SIRT, CHORT and SPANT tests). The aerobic capacity level (measured in the multistage 20 metre shuttle run test) had a significant influence on the reaction time.

Abstract
BackgroundAs an H3K27me3 demethylase and counteracts polycomb-mediated transcription repression, KDM6B has been implicated in the development and malignant progression in various types of cancers. However, its potential roles in esophageal squamous cell carcinoma (ESCC) have not been explored. MethodsThe expression of KDM6B in human ESCC tissues and cell lines was examined using qRT-PCR, immunohistochemical staining and immunoblotting. The effects of KDM6B on the proliferation and metastasis of ESCC were examined using in vitro and in vivo functional tests. RNA-seq and ChIP-seq assay were used to demonstrate the molecular biological mechanism of KDM6B in ESCC.ResultsWe show that the expression level of KDM6B increased significantly in patients with lymph node metastasis. Furthermore, we confirmed that KDM6B knockdown reduces proliferation and metastasis of ESCC cells, while KDM6B overexpression has the opposite effects. Mechanistically, KDM6B regulates TNFA_SIGNALING_VIA_NFκB signalling pathways, and H3K27me3 binds to the promoter region of C/EBPβ, leading to the promotion of C/EBPβ transcription. Besides, we show that GSK-J4, a chemical inhibitor of KDM6B, markedly inhibits proliferation and metastasis of ESCC cells. ConclusionsThe present study demonstrated that KDM6B promotes ESCC progression by increasing the transcriptional activity of C/EBPβ depending on its H3K27 demethylase activity.
Big batteries on wheels: converting diesel trains to battery electric can provide significant economic, environmental, and grid resilience benefits
Authors: Popovich Natalie , Phadke Amol , Tasar Elif 
Published: January 2021

Abstract
Nearly all locomotives in the U.S. are propelled by an electric drive that is powered by a diesel generator, the air pollution from which contributes to more than 1,000 premature deaths every year. Dramatic improvements in battery technology plus access to cheap renewable electricity open the possibility of battery-electric rail. Given that locomotives already have an electric drive, converting them to battery-electric primarily requires a battery car, which can be connected directly to the drivetrain. We examine the case for a battery-electric U.S. freight rail sector and find that one heavy-duty battery car can power a typical locomotive for 450 miles, three times the average daily distance travelled by U.S. freight trains. We find that battery-electric trains can achieve cost parity with diesel trains with electricity charging costs under 6 cents/kWh. We illustrate how these costs can be achieved with access to wholesale electricity rates. Converting the fleet to battery-electric would remove 37 million metric tons of carbon dioxide and generate total sector cost savings of $250 billion over 20 years, while introducing 238 GWh of mobile batteries that could address location-specific grid constraints during extreme events.
