Summary: This paper reviews the work at Idaho State University on the measurement of small worth reactivity samples using open loop oscillator techniques. The authors discuss the equivalency of open and closed loop techniques in terms of uncertainties in reactivity values and focus on the implementation of the easier open loop technique. They address the possibility of conducting meaningful measurements at sub-critical levels and describe their experiments in a critical and sub-critical reactor.

Summary: This paper proposes a novel sub-label learning mechanism (SLLM) to enhance domain adaptability in intelligent fault diagnosis. The SLLM utilizes the structural connectivity of the original sample space to guide distribution alignment. Experimental results demonstrate that the proposed SLLM significantly improves the domain adaptability of traditional DDA methods.

Summary: The study in Kishtwar region of Jammu and Kashmir, India, identified traces of active faults through geomorphic mapping, geological field investigations, and luminescence dating. Various tectonic landforms were mapped, indicating the presence of active extensional topography in the area. The active nature of faults was supported by dip-slip movement, fault scarp, and displacement in Holocene and recent sediments, confirmed with Ground Penetrating Radar survey.

Summary: In this article, a new load balancing fault-tolerant routing algorithm based on node contraction for LeTQ networks is proposed. The algorithm evaluates the priority of nodes using the node shrinkage method and adaptively adjusts the probability of forwarding packets to the neighbor node according to the priority of the neighbor node and the state of the network. The simulation results demonstrate that the fault-tolerant routing algorithm exhibits good performance in terms of throughput and delay.

Summary: This paper investigates the short-circuit fault in the DC line of HVDC transmission system and the capacitor voltage imbalance in MMC, and proposes a new type of MMC sub-module that has the abilities of self-clearing DC faults and self-balancing capacitor voltage. The proposed sub-module combines the half bridge and full bridge topology to effectively block fault currents and maintain consistent capacitor charge and discharge states. Simulation results in MATLAB/Simulink validate the effectiveness of the proposed sub-module in DC fault blocking and capacitor voltage balancing.

Summary: The stability of underground twin roadways is significantly affected by natural faults. A series of compression tests were conducted to investigate the combined effect of fault geometry and roadway cross-section shape on collapse behaviors. The results showed that strain localization zones mainly occurred near the roadways and joints, and the initiation locations and patterns of induced cracks were directly influenced by the roadway cross-section shape and joint inclination. The findings have important engineering significance for the design and construction of similar underground roadways in jointed rock masses.

Summary: The study focused on the material removal mechanism of high-speed cross scratches on quartz glass, showing that the intersection area is more damaged and enters brittle removal earlier. The cutting forces at different points of intersection result in varied fracture morphology. The reflection fracture of stress waves caused by impact load is the crucial factor leading to the cross-point effect of the intersection area.

Summary: Structural mapping and fieldwork in the western Arunachal Himalaya reveal crucial deformation fabrics in the Main Central Thrust (MCT) and Dirang Thrust (DT) zones, with shear senses developed at places where these faults swing. Seismicity in the area is influenced by the buried Bomdila Fault (BF), with landslides linked to transverse faulting along the Bhalukpong-Bomdila-Sela traverse.

Summary: Nonreciprocity originating from classical interactions among nonlinear scatterers is explored in this work, offering a promising tool for quantum information processing and quantum computing. It is shown that large nonreciprocal responses can be achieved in nonlinear systems by controlling the position and transition frequencies of the atoms, without requiring a nonreciprocal environment. The connection between this effect and the asymmetric population of a slowly decaying dark state is demonstrated.

Summary: This study statistically tests for the presence of power-law scaling in 61 naturally and experimentally deformed fault rocks, finding that log-normal distributions provide better fits to the data sets compared to power-law distributions. The results contradict the constrained comminution model and suggest that log-normal distributions offer a more useful description of fault-rock particle-size distributions, with potential implications for the mechanisms of cataclasis.

Summary: In this study, the brittle damage of buried pipelines under different dip-slip faults was investigated using peridynamics. It was found that pipeline failure is more likely to occur within the zone of three times the pipe diameter from the fault plane, and reverse faulting is more harmful to the pipeline than normal faulting.

Summary: This paper investigates the brittle cataclastic process of fault rocks, focusing on the structural evolution and mechanical behavior. A large-displacement direct shear model is proposed to simulate the process. The results indicate that the reduction in friction coefficient is caused by the crushing and rounding of rock fragments.

Summary: The study suggests that the Abor volcanic rocks in eastern Himalaya are of subalkaline tholeiitic affinity with continental intraplate characteristics. These volcanic rocks are likely sourced from the metasomatized mantle during the rifting event of the Indian subcontinent from Gondwana.

Summary: Significant variations in deformation style, crustal shortening rate, erosion, and exhumation are observed in the eastern Himalayan orogen. The Main Central Thrust is a major thrust system in the region, where significant crustal shortening has been estimated. The interplay of erosion and exhumation, as well as the role of transverse structures in dividing the mountain range into different sectors with diverse structural geometries, are key factors in understanding the geological processes in the region.

Summary: The Extra-Peninsular Gondwana rocks in the Arunachal Himalaya are a unique interbedded sequence between Sub-Himalayan Siwaliks and Lesser Himalayan Bomdila Group rocks, representing a basin affected by the Himalayan orogeny with different tectonic characteristics. Petrological and geochemical studies of these rocks reveal information about their provenance, tectonic setting, palaeoclimatic conditions, and weathering processes. Geochemical analysis suggests a passive margin basin configuration and the presence of illite and smectites indicating a palaeoalkaline environment of deposition for the Gondwana sediments.

Summary: The study of brittle deformation in collisional mountains helps explain shallow crustal tectonic evolution and paleostress regime. In the western Arunachal Himalaya, the Main Boundary Thrust zone displays complex imbrication with three phases of brittle deformation, preserving extensional deformation features from the pre-Himalayan period.

Summary: The tectonics and sedimentary history of the eastern segment of the Himalaya were studied using field data and U-Pb geochronology. The results showed that the area experienced a transition from open marine to shallow marine and deltaic environments, with sediments mainly sourced from the Indian Plate. After the India-Asian collision, a remnant ocean formed and eventually dried out, leading to a shift from marine to fluvial environments.

Summary: By studying the composition of carbonate minerals and silica in the faunal coal balls of Lower Gondwana Group of rocks in the Arunachal Himalaya, it was found that the carbonates in the coal balls contain Fe, Mg, and Mn, while silica in them shows the presence of hydroxylated nanometre sized alpha quartz-chalcedony. It is speculated that these phenomena may be due to repeated influx of sea water.
