Komi (Go)
Komi (コミ) in the game of Go are points added to the score of the player with the white stones as compensation for playing second. Black's first move advantage is generally considered to equal somewhere between 5 and 7 points by the end of the game. Standard komi is 6.5 points under the Japanese and Korean rules; under Chinese, Ing and AGA rules standard komi is 7.5 points; under New Zealand rules standard komi is 7 points. Komi typically applies only to games where both players are evenly ranked. In the case of a one-rank difference, the stronger player will typically play with the white stones and players often agree on a simple 0.5-point komi to break a tie ("jigo") in favour of white, or no komi at all. Komidashi (コミ出し) is the more complete Japanese language term. The Chinese term is 贴目 (tiē mù) and the Korean term is Deom (덤).

Topologies of T-Type Multilevel Inverters
Multilevel inverters (MLI) consist of a wide range of power converters. They have many designs and have been introduced with different circuit topologies such as neutral point clamped, diode clamped, cascaded H-bridges, and flying capacitors. Some of these MLIs have disadvantages, including design complexity, size, and losses due to the large number of switching devices required when they produce many output voltage levels. They are also bulky in size and may require several DC power sources.

Extra Virgin Olive Oil
Extra virgin olive oil (EVOO) is responsible for a large part of many health benefits associated with Mediterranean diet as it is a fundamental ingredient of this diet. The peculiarities of this golden highly valued product are in part due to the requirements that must be met to achieve this title, namely, it has to be obtained using exclusively mechanical procedures, its free acidity cannot be greater than 0.8%, it must not show sensory defects and it has to possess a fruity taste. All these characteristics are key factors to EVOO quality, thus the chemical composition of these many health-promoting compounds, such as unsaturated fatty acids (which are also the major compounds, especially oleic acid), as well as minor components such as tocopherols or phenolic compounds (which behave as natural antioxidants) must be preserved. Due to the presence of all these compounds, the daily consumption of EVOO entails health benefits such as cardioprotective, antioxidant, anti-inflammatory, anti-tumor properties or acting as regulators of the intestinal microbiota, among others. Taking all together, conserving EVOO chemical composition is essential to preserve its properties, so it is worth to control certain factors during storage like exposure to light, temperature, oxygen presence or the chosen packaging material, to maintain its quality and extend its shelf-life until its consumption.

Daisy Trees (Asteraceae) in Mexico
Mexico is floristically the fourth most species-rich country in the world, and Asteraceae is the most diverse vascular plant family in this country. The species exhibits a wide range of growth forms, but the tree-like habit, appropriately named daisy trees, is heavily underestimated, even though slightly different tree definitions are handled. Very little is known about their precise species number or conservation status in Mexico, so we update here the list of known Mexican daisy tree species, summarize their very diverse uses, present a general panorama of their present and future distribution, and discuss their conservation status.

Opportunities and Challenges in Developing Ocean Energy Sources
The optimal utilization of renewable energies is a crucial factor toward the realization of sustainability and zero carbon in a future energy system. Tidal currents, waves, and thermal and salinity gradients in the ocean are excellent renewable energy sources. Ocean tidal, osmotic, wave, and thermal energy sources have yearly potentials that exceed the global power demand of 22,848 TWh/y. It is expected that a better insight into ocean energy and a deep understanding of various potential devices can lead to a broader adoption of ocean energy. It is also clear that further research into control strategies is needed. Policy makers should provide financial support for technologies in the demonstration stage and employ road mapping to accelerate the cost and risk reductions to overcome economic hurdles.

Welfare Pluralism
Under the background of an accelerating population aging process, China is facing the issues of a weakening household pension function and an insufficient social pension service supply. It is urgent to establish a perfect diversified pension service supply model. The theory of welfare pluralism advocates the participation of multiple subjects in social old-age services and emphasizes that social organizations play an important role in the provision of old-age services.

Cell Wall Polysaccharides in Gram-Positive and Gram-Negative Bacteria
Certain bacteria constitute a threat to humans due to their ability to escape host defenses as they easily develop drug resistance. Bacteria are classified into gram-positive and gram-negative according to the composition of the cell membrane structure. Gram-negative bacteria have an additional outer membrane (OM) that is not present in their gram-positive counterpart; the latter instead hold a thicker peptidoglycan (PG) layer. Bacterial resistance to these drugs continues to evolve, which calls for novel antibacterial approaches to be developed.

Inclusive Fitness
In evolutionary biology, inclusive fitness is one of two metrics of evolutionary success as defined by W. D. Hamilton in 1964. An individual's own child, who carries one half of the individual's genes, is defined as one offspring equivalent. A sibling's child, who will carry one-quarter of the individual's genes, is 1/2 offspring equivalent. Similarly, a cousin's child, who has 1/16 of the individual's genes, is 1/8 offspring equivalent. From the gene's point of view, evolutionary success ultimately depends on leaving behind the maximum number of copies of itself in the population. Prior to Hamilton's work, it was generally assumed that genes only achieved this through the number of viable offspring produced by the individual organism they occupied. However, this overlooked a wider consideration of a gene's success, most clearly in the case of the social insects where the vast majority of individuals do not produce (their own) offspring.

Chlorinated Aliphatic Hydrocarbons
Chlorinated aliphatic hydrocarbons (CAHs) are ubiquitous contaminants whose presence in groundwater has persisted for many decades, mainly due to the physical-chemical characteristics of these compounds. In particular, CAHs belong to Dense Non-Aqueous Phase Liquids (DNAPLs), for which contamination scenarios differ significantly from Light NAPLs scenarios, where the separate phase floats at the top of the water table due to its lower density than water.

Millon Clinical Multiaxial Inventory
The Millon Clinical Multiaxial Inventory - Fourth Edition (MCMI-IV) is the most recent edition of the Millon Clinical Multiaxial Inventory. The MCMI is a psychological assessment tool intended to provide information on personality traits and psychopathology, including specific psychiatric disorders outlined in the DSM-5. It is intended for adults (18 and over) with at least a 5th grade reading level who are currently seeking mental health services. The MCMI was developed and standardized specifically on clinical populations (i.e. patients in clinical settings or people with existing mental health problems), and the authors are very specific that it should not be used with the general population or adolescents. However, there is evidence base that shows that it may still retain validity on non-clinical populations, and so psychologists will sometimes administer the test to members of the general population, with caution. The concepts involved in the questions and their presentation make it unsuitable for those with below average intelligence or reading ability. The MCMI-IV authors present their test as unique compared to other personality tests in that it is based on Theodore Millon' evolutionary theory and is organized according to a multiaxial format. Updates to each version of the MCMI coincide with revisions to the DSM. The fourth edition is composed of 195 true-false questions that take approximately 25–30 minutes to complete. It was created by Theodore Millon, Seth Grossman, and Carrie Millon. The test is modeled on four categories of scales:

Composition of Nuts
The possibility that nut intake may defend human health is an interesting point of view and has been investigated worldwide. Consequently, nuts are commonly promoted as healthy. The number of investigations proposing a correlation between nut consumption and a decrease in the risk of key chronic diseases has continued to increase. Nuts are a source of intake of fiber, and dietary fiber is associated with a reduced occurrence of obesity and cardiovascular diseases. Nuts likewise provide minerals and vitamins to the diet and supply phytochemicals that function as antioxidant, anti-inflammatory, and phytoestrogens agents and other protective mechanisms.

Urinary Tract Infections
Urinary tract infections (UTIs) affect any part of the urinary tract and may spread through the urinary tract towards the urethra, bladder and even the kidneys and they are associated with an increase in morbidity and mortality. UTIs may be resolved spontaneously or treated with antibiotics. However, regular use of antibiotics is related to nephrotoxicity and  produces changes in the intestinal flora, alter immunity and metabolism, and finally, gut bacteria become a reservoir of genes for resistance to antibiotics. Regarding this concern, a new group of molecules called drug conjugates have been proposed as an alternative or a complement to de use of just antibiotics such as a new adjuvant in UTIs therapy called Itxasol©.
