Abstract. A puzzle box (also known as a trick box) is a box that may be opened by solving some obstacles originally designed by the manufacturer. Some puzzle boxes may be opened with a few moves, while others call for problem-solving and decision-making skills to unlock all the blocks inside the box. Puzzle boxes have existed throughout the ancient ages of the east and west, and their popularity has grown significantly since the 17th century. Chinese puzzle boxes are classified into four types based on the first movement during the initial opening stage: whole-box rotation, mechanical-member s

In spite of being based on drastic simplifications, the H?ckel molecular orbital (HMO) quantum-mechanical model provides a reasonably good description of the properties of ?-electrons in conjugated molecules. The HMO approach is found to be particularly successful in the case of the total ?-electron energy (E), by means of which it is possible to calculate enthalpies of formation and similar thermodynamic characteristics of conjugated compounds. In this paper it is shown that expressions equivalent to E can be deduced within much more accurate quantum mechanical considerations. This might expl

This paper takes one step towards this larger goal by studying how Exhaustive Procedural Content Generation (EPCG) can be used for analysis of incremental changes of existing game levels.

New insights have come from the unconventional myosins, especially myosin V. Myosin V is kinetically tuned to allow movement on actin filaments as a single molecule, which has led to new kinetic, mechanical and structural data that have filled in miss

In recent years, several automated analysers that prepare and stain blood smears have been introduced in clinical laboratories. Despite the use of instrumental settings based on physical characteristic of individual samples, traumatic injuries of neutrophil and lymphocytes can be observed. Some samples present a very high percentage of damaged cells, allowing the speculation that a cellular susceptibility may enhance mechanical traumatism. These artefacts can puzzle morphological evaluation in both traditional and digitised microscopy; in addition, unskilled operators can be misled.

The extent and distribution of particle agglomeration were theoretically and experimentally investigated by zeta potential and particle si

Abstract:

There is a long-standing puzzle concerning whether polyethylene blends are a suitable substitution for cable-insulation-used crosslinking polyethylene (XLPE) especially at elevated temperatures. In this paper, we investigate temperature dependence of mechanical, electrical properties of blends with 70 wt % linear low density polyethylene (LLDPE) and 30 wt % high density polyethylene (HDPE) (abbreviated as 70 L-30 H). Our results show that the dielectric loss of 70 L-30 H is about an order of magnitude lower than XLPE, and the AC breakdown strength is 22% higher than XLPE at 90 °C. Moreover, th

Abstract:

The study on property degradation of damaged composite laminates is extended to anisotropic laminates with matrix cracking. In Part 1 of the paper, an idea of “stiffness partition” is proposed to deal with the puzzle that the in-plane normal response is coupled with the shear response of the laminates. For (θ m/90 n), laminates containing transversely cracked layers under general in-plane loading, the constitutive relations are derived and the effective stiffnesses are expressed as the functions of crack density.

Abstract:

Historically, solving the Rubik's Cube has been a challenging puzzle for both enthusiasts and researchers. An innovative electronic Rubik’s Cube solver has been developed, incorporating advanced algorithms and robotic arms that rotate the cube to expose each face for scanning by a camera. The scanned data is processed by a Rubik’s Cube-solving algorithm running on a Nios II processor. This algorithm determines the necessary moves to solve the cube, and these instructions are sent to the FPGA. The FPGA generates PWM signals that control servo motors, which in turn rotate the cube to

Abstract:

AbstractTopology optimization is a pioneer design method that can provide various candidates with high mechanical properties. However, high resolution is desired for optimum structures, but it normally leads to a computationally intractable puzzle, especially for the solid isotropic material with penalization (SIMP) method. In this study, an efficient, high-resolution topology optimization method is developed based on the superresolution convolutional neural network (SRCNN) technique in the framework of SIMP. SRCNN involves four processes, namely, refinement, path extraction and representation

Abstract:

The polygonal shape of cells in proliferating epithelia is a result of the tensile forces of the cytoskeletal cortex and packing geometry set by the cell cycle. In the larval Drosophila epidermis, two cell populations, histoblasts and larval epithelial cells, compete for space as they grow on a limited body surface. They do so in the absence of cell divisions. We report a striking morphological transition of histoblasts during larval development, where they change from a tensed network configuration with straight cell outlines at the level of adherens junctions to a highly folded morphology.

Nutshells achieve remarkable properties by optimizing structure and chemistry at different hierarchical levels. Probing nutshells from the cellular down to the nano- and molecular level by microchemical and nanomechanical imaging techniques reveals insights into nature's packing concepts. In walnut and pistachio shells, carbohydrate and lignin polymers assemble to form thick-walled puzzle cells, which interlock three-dimensionally and show high tissue strength. Pistachio additionally achieves high-energy absorption by numerous lobes interconnected via ball-joint-like structures. By contrast, t

Hypoxia, particularly hypobaric hypoxia, is a multifaceted entity which includes certain molecular, patho-physiological and biochemical aspects. Any single aspect in itself cannot help us elucidate hypobaric hypoxia in its entirety. We observed three crucial lacunae within the existing literature. These include a lack of high-throughput investigations into redox PTMs, particularly NO-based PTMs; a prophylactic supplement with proven efficacy and safety which doesn’t involve medical supervision and is not contraindicated in hepatic, renal and cardiac insufficiencies; and a clinically validated

Abstract:

Cardiac metabolism represents a crucial and essential connecting bridge between the healthy and diseased heart. The cardiac muscle, which may be considered an omnivore organ with regard to the energy substrate utilization, under physiological conditions mainly draws energy by fatty acids oxidation. Within cardiomyocytes and their mitochondria, through well-concerted enzymatic reactions, substrates converge on the production of ATP, the basic chemical energy that cardiac muscle converts into mechanical energy, i.e., contraction. When a perturbation of homeostasis occurs, such as an ischemic eve
