Towards real-world complexity: an introduction to multiplex networks
Many real-world complex systems are best modeled by multiplex networks of
interacting network layers. The multiplex network study is one of the newest
and hottest themes in the statistical physics of complex networks. Pioneering
studies have proven that the multiplexity has broad impact on the system's
structure and function. In this Colloquium paper, we present an organized
review of the growing body of current literature on multiplex networks by
categorizing existing studies broadly according to the type of layer coupling
in the problem. Major recent advances in the field are surveyed and some
outstanding open challenges and future perspectives will be proposed.Comment: 20 pages, 10 figure
Robotic Sacrocolpopexy for Treatment of Prolapse of the Apical Segment of the Vagina
Abdominal sacrocolpopexy for apical prolapse repair is the gold standard treatment and is more effective and durable than the transvaginal approach. The increase in minimally invasive surgery has led to attempts at laparoscopic sacrocolpopexy, but this technique has not gained popularity due to complex procedures and a steep learning curve. Robotic sacrocolpopexy overcomes these issues and has yielded good results for more than 15Ā years, with equivalent outcomes and safety to open and laparoscopic sacrocolpopexy (LSC). LSC is still a useful procedure for experienced surgeons, but it is expected that robot-assisted sacrocolpopexy (RSC) will have better results overall due to the advantages of the robotic instrument. The most important advantage is that surgeons who are inexperienced with minimally invasive approaches can more readily master RSC compared to overcoming the steep learning curve of LSC
Synergistic multi-doping effects on the Li7La3Zr2O12 solid electrolyte for fast lithium ion conduction.
Here, we investigate the doping effects on the lithium ion transport behavior in garnet Li7La3Zr2O12 (LLZO) from the combined experimental and theoretical approach. The concentration of Li ion vacancy generated by the inclusion of aliovalent dopants such as Al(3+) plays a key role in stabilizing the cubic LLZO. However, it is found that the site preference of Al in 24d position hinders the three dimensionally connected Li ion movement when heavily doped according to the structural refinement and the DFT calculations. In this report, we demonstrate that the multi-doping using additional Ta dopants into the Al-doped LLZO shifts the most energetically favorable sites of Al in the crystal structure from 24d to 96āh Li site, thereby providing more open space for Li ion transport. As a result of these synergistic effects, the multi-doped LLZO shows about three times higher ionic conductivity of 6.14āĆā10(-4)āS cm(-1) than that of the singly-doped LLZO with a much less efforts in stabilizing cubic phases in the synthetic condition
Patome: a database server for biological sequence annotation and analysis in issued patents and published patent applications
With the advent of automated and high-throughput techniques, the number of patent applications containing biological sequences has been increasing rapidly. However, they have attracted relatively little attention compared to other sequence resources. We have built a database server called Patome, which contains biological sequence data disclosed in patents and published applications, as well as their analysis information. The analysis is divided into two steps. The first is an annotation step in which the disclosed sequences were annotated with RefSeq database. The second is an association step where the sequences were linked to Entrez Gene, OMIM and GO databases, and their results were saved as a geneāpatent table. From the analysis, we found that 55% of human genes were associated with patenting. The geneāpatent table can be used to identify whether a particular gene or disease is related to patenting. Patome is available at ; the information is updated bimonthly
Triclinic Na3.12Co2.44(P2O7)(2) as a High Redox Potential Cathode Material for Na-Ion Batteries
Two types of sodium cobalt pyrophosphates, triclinic Na3.12Co2.44(P2O7)(2) and orthorhombic Na2CoP2O7, are compared as high-voltage cathode materials for Na-ion batteries. Na2CoP2O7 shows no electrochemical activity, delivering negligible capacity. In contrast, Na3.12Co2.44(P2O7)(2) exhibits good electrochemical performance, such as high redox potential at ca. 4.3 V (vs. Na/Na+) and stable capacity retention over 50 cycles, although Na3.12Co2.44(P2O7)(2) delivered approximately 40 mA h g(-1). This is attributed to the fact that Na2CoP2O7 (similar to 3.1 angstrom) has smaller diffusion channel size than Na3.12Co2.44(P2O7)(2) (similar to 4.2 angstrom). Moreover, the electrochemical performance of Na3.12Co2.44(P2O7)(2) is examined using Na cells and Li cells. The overpotential of Na cells is smaller than that of Li cells. This is due to the fact that Na3.12Co2.44(P2O7)(2) has a smaller charge transfer resistance and higher diffusivity for Na+ ions than Li+ ions. This implies that the large channel size of Na3.12Co2.44(P2O7)(2) is more appropriate for Na+ ions than Li+ ions. Therefore, Na3.12Co2.44(P2O7)(2) is considered a promising high-voltage cathode material for Na-ion batteries, if new electrolytes, which are stable above 4.5 V vs. Na/Na+, are introduced.
Management of Hunner Lesion in Interstitial Cystitis/Bladder Pain Syndrome Patients
Interstitial cystitis/bladder pain syndrome (IC/BPS) is a chronic condition characterized by chronic pelvic pain related to the bladder. One phenotype of IC/BPS is the Hunner lesion type IC/BPS. Hunner lesion exhibits typical features such as mucosal ulceration, fibrosis, and severe inflammation. The tissue surrounding the Hunner lesion may show lymphoplasmacytic infiltrates, and mast cells are increased in the lamina propria. In this chapter, we discuss intravesical treatment, endoscopic treatment, and partial cystectomy with augmentation cystoplasty for the management of Hunner lesion in IC/BPS patients
Acupuncture Muscle Channel in the Subcutaneous Layer of Rat Skin
AbstractUsing a mixed-dye injection technique, we found a novel kind of muscle fiber with a lumen, established its precise location in the subcutaneous muscle layer along the acupuncture muscle of the bladder line, and determined its detailed ultrastructure. The channels with flowing liquid were a novel kind of muscle fibers with lumens and they were located in the subcutaneous muscle layer of rat. Their detection was realized by using chrome-hematoxylin and a mixture of fluorescent nanoparticles and commercial Pelikan ink. These acupuncture muscle channels were hidden among the neighboring skin skeletal muscle fibers and were barely distinguishable from them with light microscopes. Only with a transmission electron microscope were their characteristic features shown to be different from normal skin skeletal muscle. These features included undifferentiated muscle fibers that resembled immature myofibrils without Z-lines and reassembled telophase nuclei
Comparing Cardiopulmonary Functions of National Race Walkers by Walking and Running during Graded Exercise Testing
PURPOSE This study aimed to identify a sport-specific assessment for elite race-walking athletes by comparing physiological responses between walking and running graded exercise test (GXT) protocols. METHODS Six elite race-walking athletes completed both walking and running protocols in a randomized crossover design with 1 week interval between trials. Maximal oxygen consumption (VO2max), ventilation (VE), and heart rate (HR) were measured throughout and after each trial, and blood lactate levels were collected during the recovery period. RESULTS There were significant differences in VO2max, VE, and HR values between the walking and running protocols (p<.001). During the recovery period, VO2max, VE, HR, and blood lactate levels were significantly different in each measurement (p<.001); however, there was no difference between the walking and running protocols. CONCLUSIONS Based on these results, both the walking and running GXT protocols were inappropriate for assessing elite race-walking athletes. This study suggests that a supplement GXT protocol is required to specifically assess elite race-walking athletes
