Abstract
Horgan, BG, Tee, N, West, NP, Drinkwater, EJ, Halson, SL, Colomer, CME, Fonda, CJ, Tatham, J, Chapman, DW, and Haff, GG. Acute performance, daily well-being and hormone responses to water immersion after resistance exercise in junior international and subelite male volleyball athletes. J Strength Cond Res 37(8): 1643–1653, 2023—Athletes use postexercise hydrotherapy strategies to improve recovery and competition performance and to enhance adaptative responses to training. Using a randomized cross-over design, the acute effects of 3 postresistance exercise water immersion strategies on perceived recovery, neuromuscular performance, and hormone concentrations in junior international and subelite male volleyball athletes (n = 18) were investigated. After resistance exercise, subjects randomly completed either 15-minute passive control (CON), contrast water therapy (CWT), cold (CWI), or hot water immersion (HWI) interventions. A treatment effect occurred after HWI; reducing perceptions of fatigue (HWI > CWT: p = 0.05, g = 0.43); improved sleep quality, compared with CON (p < 0.001, g = 1.15), CWI (p = 0.017, g = 0.70), and CWT (p = 0.018, g = 0.51); as well as increasing testosterone concentration (HWI > CWT: p = 0.038, g = 0.24). There were trivial to small (p < 0.001–0.039, g = 0.02–0.34) improvements (treatment effect) in jump performance (i.e., squat jump and countermovement jump) after all water immersion strategies, as compared with CON, with high variability in the individual responses. There were no significant differences (interaction effect, p > 0.05) observed between the water immersion intervention strategies and CON in performance (p = 0.153–0.99), hormone (p = 0.207–0.938), nor perceptual (p = 0.368–0.955) measures. To optimize recovery and performance responses, e.g., during an in-season competition phase, postresistance exercise HWI may assist with providing small-to-large improvements for up to 38 hours in perceived recovery (i.e., increased sleep quality and reduced fatigue) and increases in circulating testosterone concentration. Practitioners should consider individual athlete neuromuscular performance responses when prescribing postexercise hydrotherapy. These findings apply to athletes who aim to improve their recovery status, where postresistance exercise HWI optimizes sleep quality and next-day perceptions of fatigue.

Abstract
Coral silt foundation is deposited from marine land reclamation. Different soil types, including coral sand, silt, and clay with different particle diameters, are distributed in different areas through sorting and deposition. As a new type of fine-grained coral silt, the coral silt is made up of more than 50 % of particles with a grain diameter of less than 0.075 mm. This part of the fine-grained coral silt interlayer will affect the bearing capacity and cause uneven settlement of the coral silt foundation. To obtain the shear characteristics of coral silt, a series of consolidation undrained triaxial experiments were conducted on clean coral silt and coral silt-sand mixtures. The results show that the undrained behavior of coral silt displayed a strain-softening behavior. For clean coral silt, undrained peak strength and critical state shear strength were significantly dependent on the dry density. The undrained peak shear strength and critical state shear strength increase as the dry density increases. For coral silt-sand mixtures, as the coral sand content increased up to a threshold value (about 20 %), the undrained peak shear strength and critical state shear strength decreased. However, with a further increase in coral sand content, the undrained peak shear intensity and steady-state intensity began to increase.

ÖZET
Mühimmat aerodinamiği çalışmaları, uçuş süresi boyunca çok farklı akış rejimlerinden geçen ve çok yüksek manevra kabiliyetine sahip olması gereken bir hava aracının oldukça sınırlı bir aerodinamik yüzey ile kontrol edilebilmesini gerektirmektedir. Bu zor hedefler tipik olarak, ön tasarım sürecinde basitleştirilmiş bir ön tasarım aracı ile binlerce farklı kanat-gövde seçeneğinin denenmesi ile gerçekleştirilmeye çalışılmaktadır. Bu aşamada, bulunan alternatif mühimmat geometrileri detaylı tasarım aşamasında HAD analizleri ile incelenmeye başlanmaktadır. Ancak bu aşama uzun ve maliyetli bir ön işlemleme iş yükünü içermektedir. Bu sebeple, ön tasarımdan gelen mühimmat geometrileri sınırlı sayıda tutulmaktadır. Ön tasarım araçlarının yeterince hassas çözüm veremediği düşünüldüğünde bu geçişin daha az maliyetli ancak çok daha hassas yöntemlerle yapılması gerektiği ortaya çıkmaktadır. Bu çalışmada popüler bir mühimmat aerodinamiği hızlı analiz programı olan Missile-DATCOM formatını kullanan, tamamen otomatik olarak çözüm hacmi ve çözüm ağı oluşturabilen yeni bir teknoloji geliştirilmiştir. Bu teknoloji ile mühimmat çevresi çok yüksek kalitede yapısal ağlarla örülmektedir. Kontrol kanatçıklarına istenilen açılar verilebilmekte ve istenilen uçuş şartlarında analiz koşulabilmesini sağlamaktadır. HAD analizleri Chimera ağ çözüm yeteneği bulunan ve laboratuvarımızda geliştirilmekte olan sıkıştırılabilir HAD çözücü ile gerçekleştirilmiş ve deney sonuçları ile çok iyi bir uyum gözlenmiştir.

The genetic etiology of critical congenital heart disease
Authors: Mendha Aishwarya 
Published: April 2023

Congenital Heart Disease (CHD) is the most common kind of birth defect. Congenital heart disease is the most common birth defect and the leading cause of death in newborns. The causes of CHD are complicated and involve both genes and the environment. Congenital heart disease includes problems with the septum, the valves, and the outflow tract. Correctional heart surgery and new strategies for managing CHD have massively enhanced life expectancy. 490 percent of CHD newborns who live through their first year will become adults. Studies of the molecular genetics of humans and animal models of development are enhancing our understanding of normal heart development and cardiac diseases. A recent study demonstrates that microRNAs are implicated in congenital heart diseases. Epigenetic variables were eventually revealed to influence heart development. Several genes are responsible for congenital cardiac abnormalities as well as genetic disorders. This paper describes the categorization, environmental, and genetic causes of Coronary Heart Disease (CHD), the role of key CHD-causing genes, and potential options for preventing CHD.

The consumption of electricity in Malaysia increase in demand as one of the driving forces of economic development. The main source of electric power generation in Malaysia depends on fossil fuels which lead to air pollution currently and a shortage of natural resources (fossil) in the future if this method continues. Moreover, this will cause a serious problem such as sustainability of energy choice and will harm the environment. This study investigates the relationship between climate variables and electric power consumption in Malaysia. The important climate variables included such as average temperature, average rainfall, forest area, carbon dioxide emission and arable land over a period of 1991 to 2015. Augmented Dickey-Fuller unit root test shows that average rainfall, average temperature, and electrical power consumption stationary at their level. However, forest area, carbon dioxide emission, and arable land stationary after first differences. The result of this study indicates that electric power consumption has a long-run relationship between average temperature and average rainfall. This indicates that electric power consumption has an impact on climate change in Malaysia. These studies also find evidence that unidirectional causality between electric power consumption and climate factors. Overall, the wise consumption of electricity and adopting renewable energy to generate electricity will reduce carbon emission in Malaysia.
Determination of site amplification in the Los Angeles urban area from inversion of strong-motion records
Authors: Harmsen Stephen C. 
Published: April 2023

AbstractThe amplification of strong ground motion at sites in the greater Los Angeles, California, region is determined using the generalized-inverse method of Andrews (1986). Site-amplification estimates are determined at 281 strong-motion sites that provided horizontal-component accelerograms from the 1971 San Fernando, 1987 Whittier Narrows, 1991 Sierra Madre, or 1994 Northridge mainshocks. The estimates are determined relative to the spectral level recorded at a single reference site. In a second inversion, a source-site interaction term is added to Andrews's (1986) model to quantify the effect selected mainshock records have on site-amplification estimates. The source-site interaction term is applied to the San Fernando Valley sites' records of the Northridge earthquake and to three Los Angeles basin sites' records of the Whittier Narrows mainshock.Site-amplification spectra are averaged within two frequency bands: the intermediate-frequency band (IFB) from 0.5 to 1.5 Hz and the high-frequency band (HFB) from 2 to 6 Hz. Results are displayed on maps of surficial geology. Average spectral levels are correlated with average shear-wave velocity in the uppermost 30 m, a geotechnical parameter used by the National Earthquake Hazards Reduction Program (NEHRP) to characterize site amplification. Statistically significant correlation is found in both frequency bands. Average spectral amplification levels for NEHRP class B, C, and D sites in the LA urban area are determined. These averages display an expected increase in spectral amplification with category, with a more pronounced variation in the IFB than in the HFB. Considerable overlap in the one-standard-deviation range of the C and D site levels is found in both IFB and HFB, suggesting that site-specific spectral amplification is influenced by more than just near-surface shear-wave velocity. Average site-amplification levels are compared with those obtained from Northridge aftershock records at 28 collocated sites and are found to be in reasonably good agreement in both frequency bands. Some interesting outliers, that is, sites for which the mainshock- and aftershock-determined amplifications differ significantly, are identified as sites that experienced ground failure during the Northridge mainshock.
Estimating the diminution of shear-wave amplitude with distance: Application to the Los Angeles, California, urban area
Authors: Harmsen Stephen C. 
Published: April 2023

AbstractThe rate of decay with distance of shear-wave amplitude, computed from 20-sec S-wave spectra, is determined from TERRAscope records of small earthquakes in the greater Los Angeles area. Piecewise log-linear interpolation functions and traditional diminution functions are used to fit spectral decay to a maximum distance of 150 km. Simultaneously, isotropic source and receiver terms are determined. Separate branches of the spectral decay function are found for two categories of source depth: greater than 10 km and less than 10 km. In the hypocentral distance range of 20 to 150 km and in the frequency range of 0.5 to 8.0 Hz, an important result of the investigation is that the horizontal-component decay rate associated with deeper-crustal sources is generally greater than that associated with shallower sources and is greater than that which is estimated using more traditional models of spectral decay with distance. The same behavior generally holds for vertical-component spectra. The variation in apparent attenuation rate with source depth should affect seismic-hazard estimates associated with the rupture of blind thrust faults in the Los Angeles basin and vicinity. The results of the inversions suggest that interpolation function representations of spectral decay are sensitive to perturbations of S-wave amplitude due to crustal reflectors, such as post-critical S-wave arrivals from mid-crustal to deep-crustal velocity interfaces.
Approximation of rupture directivity in regional phases using upgoing and downgoing wave fields
Authors: Saikia Chandan K. , Helmberger D. V. 
Published: April 2023

AbstractRecent broadband modeling of regional events suggests that vertical directivity is particularly important at high frequency. Conventionally, such directivity is obtained by summing a grid of point sources. This relatively time-consuming procedure can be greatly reduced by introducing directivity time histories appropriate for the various crustal phases in terms of upgoing and downgoing paths that are calculated at only one depth. To achieve this, we formulated frequency-wavenumber solutions for a simultaneous computation of surface displacement for three wave fields, upgoing, downgoing, and the total from a seismic source buried in a layered medium (Appendix A). The concept of upgoing and downgoing wave field is introduced in the source layer matrix explicitly before allowing the source coefficients to interact with the propagation of the stress-displacement vector. Using this new algorithm, we generated a set of upgoing and downgoing wave fields at a fixed depth for different crustal models. We also simulated the effects of rupture propagation using distributed point-source summations and predicted the same effect by summing the upgoing and downgoing wave fields calculated at a single depth, each convolved with a separate analytical boxcar function representing the far-field rupture. A library of these new Green's functions should prove much more effective in modeling recorded motions than using point-source Green's functions alone.
The fault ruptures of the 1976 Tangshan earthquake sequence inferred from coseismic crustal deformation
Authors: Huang Bor-Shouh , Tein Yeh Yeong 
Published: April 2023

AbstractThe Tangshan, China, earthquake with magnitude MS = 7.8 occurred on 28 July 1976. Two large aftershocks (called the Luanxian and Ningho earthquakes) followed within a few months. The three major events and other small aftershocks make up the complete Tangshan earthquake sequence. Trilateration measurements and precise levelings were made in the Tangshan area before and after these shocks. In this study, the coseismic surface deformation of the Tangshan area is modeled by the finite-element method to infer the fault geometries and slip distributions of the sequence. Results show that most of the crustal deformation of the Tangshan area was associated with right-lateral slip on a NNE-striking mainshock fault rupture plane together with the ruptures of the two major aftershocks. The fault associated with the mainshock rupture can be divided into southern and northern subfaults with different strikes, dips, and rakes, and inhomogeneous slip distributions. The rupture processes are reconstructed here by the complement of source time functions determined by teleseismic waveform modeling. The Luanxian earthquake was associated with pure normal faulting on a plane dipping 53° N, while the Ningho earthquake was associated with a left-lateral strike-slip faulting with a small normal component. The focal mechanisms of the Tangshan earthquake sequence are consistent with regional tectonics, that is, extensive right-lateral strike-slip fault movement in a NNE direction and associated NE-SW-directed compression. The rupture lengths are 48 km for the mainshock, 18 km for the Luanxian earthquake, and 20 km for the Ningho earthquake. The averaged stress drops are 45 ± 5.5 bar for the mainshock, 34 ± 3.2 bar for the Luanxian earthquake, and 15 ± 1.9 bar for the Ningho earthquake. The high stress drop of the Tangshan earthquake, as compared with other intraplate earthquakes, can be correlated to its long return period inferred from Chinese historical earthquake catalogs.
The Greenland earthquake of 11 July 1987 and postglacial fault reactivation along a passive margin
Authors: Chung Wai-Ying , Gao Hong 
Published: April 2023

AbstractIntraplate earthquakes, in many cases, occur near continental margins. This observation applies very well to the case of Greenland, a stable continental region with low seismicity. The seismicity of Greenland is nearly totally concentrated along the coastlines of the island, where it is relatively free of ice cover. On 11 July 1987, the largest Greenland earthquake of instrumental record (mb = 5.5, Mw = 5.4) occurred in continental crust off the northeastern coast in the Wandel Sea. Waveforms of long- and short-period teleseismic P and long-period teleseismic SH waves have been modeled to estimate the source parameters for this earthquake. The focal mechanism determined is a normal faulting with a strike-slip component (strike = 148°, dip = 59°, and rake = −131°). The strike direction of one of the nodal planes was found to be consistent with the direction of the dominant structural trend observed in the area. A previous normal faulting mechanism with very different strike directions for this event was found to have inferior waveform fit and is not consistent with the fault strike directions from the local geological setting. The seismic moment of the July 1987 earthquake is 1.75 × 1024 dyne-cm. The focal depth and stress drop are 5 km and 389 bars, respectively. The high stress drop may relate to the relatively long earthquake repeat time in the region. The observed normal faulting of this earthquake can be interpreted as a rupture due to an extensional stress field at the forebulge outside of the ice sheet because of deglaciation flexure in the region. Another major earthquake (26 November 1971; mb = 5.1) 311 km to the south of the 11 July 1987 event was likewise determined to be normal faulting and can be explained as another event triggered by deglaciation. In addition, we find that the sparse general seismicity of Greenland can also be related to postglacial rebound.
