Summary: This paper presents a theoretical analysis of the effects of boundary conditions on the solutions of one-dimensional hemodynamics. The study shows that unphysical unbounded solutions can occur when using bounded functions as boundary conditions. The use of a periodic boundary condition leads to the correct behavior of the solution, and an effective Fourier method is proposed for analytical solutions. The obtained results expand the possibilities of using analytical methods in blood-flow simulation and can be valuable for specialists in the field.

Summary: In this study, the long-term effects of high-frequency oscillations on translational and angular motion are systematically evaluated. It is shown that rapid oscillations can cause a bias in the average direction of progression, and the impact of yawing on propulsion speed and hydrodynamic shape is quantified.

Summary: The direct simple shear (DSS) test is a commonly used method to assess soil shear strength, estimate liquefaction resistance, or calibrate constitutive models. This study found that near-frictionless vertical boundaries can approximate simple shear conditions, and the effect of top-cap tilting on the test results can be negligible. However, vertical compliance can greatly affect the stress-strain response.

Summary: This article introduces a multi-level computational pipeline using graph-based methods to study the mechanism of chemical reactions. By constructing an ensemble of molecular catalysts and considering multiple conformations, reaction selectivity can be accurately predicted. The effectiveness of this approach is demonstrated through the study of a Rh(iii) catalyzed reaction.

Summary: The study presents a 2D streamwise velocity model based on RANS for predicting boundary shear stress and velocity in free surface streams. Key aspects include treatment of boundary conditions and novel modifications for low computational cost. The model shows good agreement with experimental cases of different cross-section shapes and roughness conditions, indicating significant impact of free surface boundary layer in windy conditions on streamwise velocity and boundary shear stress.

Summary: Clinical trial data-sharing is crucial for research integrity. However, early experiences have been unsatisfactory because of improper conduct. We propose 10 rules for researchers to follow, including abiding by legal requirements, involving research participants, determining data access methods, and striving for excellence.

Summary: An experimental program on Ticino sand was conducted to investigate the influence of initial static shear stress on failure mechanism, cyclic resistance, and pore water pressure generation. The results showed that the sand exhibited two types of failure mechanisms, cyclic mobility and plastic strain accumulation, depending on the magnitude of the initial static shear stress. The cyclic resistance of the sand was found to either increase or decrease with an increasing initial static shear stress, depending on the density state of the sand. Furthermore, the study suggested that the K alpha correction factors could depend on particle gradations and grain shape.

Summary: Down syndrome (DS) is characterized by a collection of clinical features including intellectual disability, congenital malformations, and susceptibility to infections and autoimmune diseases. Growing evidence suggests that genes IFNAR1 and IFNAR2 on chromosome 21 play a key role in the pathogenesis of DS by encoding the two subunits of the receptor for type I interferons (IFN-I). This review highlights the potential for novel therapeutic avenues by comparing and contrasting DS to other IFN-mediated conditions.

Summary: This paper presents rotating periodic boundary conditions (PBCs) for simulating uniaxial stretching flow (USF) or biaxial stretching flow (BSF) in nonequilibrium molecular dynamics (NEMD). Specialized PBCs are required for such nonequilibrium flows as the simulation box deforms with the background flow. The proposed technique is simpler than previous PBCs developed for general three dimensional flows and offers better minimum lattice spacing properties.

Summary: Granular soils exhibit directional diversity in stiffness at small strains, influenced by particle shape and orientation. A series of shear wave propagation tests revealed that elongated particle shapes induce greater anisotropy in small-strain shear modulus G(0). Additionally, differences in S-wave velocities were observed based on particle orientation, affecting the anisotropy of G(0).

Summary: The simple-shear condition is more realistic than the direct-shear condition for simulating the mechanical behavior of vegetated soil slope under shallow failure. However, there is still insufficient study on the simple-shear characteristics of vegetated slopes, and there is a lack of intuitive comparison between these two shear conditions. This study conducted large-scale simple-shear and direct-shear experiments on soil permeated by roots to investigate the shear strength and stiffness.

Summary: This study focuses on the rock composition and evolution of the Himalayan core complex, demonstrating that both Greater Himalayan sequence (GHS) and Lesser Himalayan sequence (LHS) rocks in the Gurla Mandhata core complex originated from the hanging wall of the Main Central thrust (MCT) and experienced Cenozoic Himalayan metamorphism. The research highlights the importance of using isotopic analysis in conjunction with petrochronological and structural data to characterize rock units and structures in the Himalayas.

Summary: The Huai'an Complex in the North China Craton consists of TTG gneisses and granite intrusive bodies. Zircon U-Pb ages reveal three episodes of magmatism from 2.6-2.3 Ga, 2.0-1.7 Ga, and similar ages around 2.3-2.0 Ga, indicating different magma sources. The complex underwent crustal growth and reworking stages from 3.1-2.5 Ga to 1.95-1.7 Ga, with tectonic processes of compression-extension-compression during 2.6-1.7 Ga.

Summary: In this study, new zircon (U-Th)/He (ZHe) ages and zircon fission track (ZFT) ages were analyzed from an age-elevation profile in Machu Picchu, Peru. The ZFT data showed older ages compared to other thermochronological data, while the ZHe data interestingly showed ages similar to apatite (U-Th)/He (AHe). It was proposed that He retention in zircon is linked to the damage dose, with a closure temperature that varies with alpha-dose. The study suggests that the closure temperature of ZHe at low alpha-dose ranges from 6 x 10(15) to 4 x 10(16) alpha/g, and is lower than previously thought. These findings strengthen previous geological conclusions and highlight a cooling rate at Machu Picchu that is approximately twice as important as deduced from AHe and apatite fission track data alone.

Summary: Traditional strain analysis assumes that particles deform affinely with their matrix, but in reality there are opposing forces that resist particle deformation. This study investigates the effect of surface tension on the deformation of weak viscous particles and finds that capillary number plays a controlling role in particle deformation.

Summary: This study used thermochronology and thermal modeling to decipher the thermal history of the Patagonian Andes. The results revealed an Early Cretaceous cooling event in the foreland, and predominant Cenozoic cooling events in the hinterland. The study also ruled out the resetting of thermochronological systems due to the formation of an asthenospheric window, and highlighted increased cooling rates in response to enhanced glacial erosion after 7 million years ago.

Summary: This research uses various methods such as cosmogenic nuclide dating, surface creep rate quantification, and finite element modeling to investigate the Holocene development of the Bleis Marscha rock glacier. The study reveals that the formation of the rock glacier is influenced by climate change and the dynamics of older generations are less sensitive to climate. This work contributes to understanding the long-term development and climate sensitivity of rock glaciers.
