Heat Pump
The Heat Pump (HP) is an environmentally friendly and renewable energy technology that exploits renewable heat energy from the ground, air or water for building or industrial applications by reversing the natural heat flow from a lower to a higher useful temperature. HP technology is commonly classified according to its source, function, type of energy and application. The HPs in cold climate countries are accepted as one of the most outstanding technologies of heating in both residential and commercial buildings, because they provide high seasonal performance factor (SPF), 1.8–3.4 for air source heat pump (ASHP) and 2.5–5.6 for ground source heat pump (GSHP) and water source heat pump (WSHP). However, the spread is large, because of different equipment, design and installation quality as well as maintenance.

Tumor Spheroids and Organoids
Understanding and investigating tumors is carried out by researchers using a number of different methods. One exciting and promising area is 3D tumor models including spheriod and organoid models. They act in similar ways to tumors which means we can use them to gather important information. This ranges from the way tumors react through to how different treatments may work on tumors. Ultimately they may help guide us towards the types of drugs and therapies that could be used to treat tumors. This work gives an overview of these technologies, the types of 3D models available and how they can be used to improve treatments and their applications in personalized medicine.

Understanding the Education Policymaking Process in the United States
Considering the broad implications of education policy, it is important to understand the various facets of the education policymaking process. There are different stages of the process (i.e., issue definition, policy adoption, implementation, and evaluation) which, at times, can be difficult to comprehend when considering the competing goals of education and multiple stakeholders. Understanding the process can also be difficult due to the historical and contemporary influences of power and racism at play within and outside of society’s educational landscape—especially within the United States context. The process is highlighted as an iterative one which provides room for adjustments and changes across different contexts. By navigating the complex landscape of education policymaking, one can be better equipped to understand the intricacies of policymaking and its transformative capacity.

Core (Game Theory)
In cooperative game theory, the core is the set of feasible allocations that cannot be improved upon by a subset (a coalition) of the economy's agents. A coalition is said to improve upon or block a feasible allocation if the members of that coalition are better off under another feasible allocation that is identical to the first except that every member of the coalition has a different consumption bundle that is part of an aggregate consumption bundle that can be constructed from publicly available technology and the initial endowments of each consumer in the coalition. An allocation is said to have the core property if there is no coalition that can improve upon it. The core is the set of all feasible allocations with the core property.

Lusterware
Lusterware or Lustreware (respectively the US and all other English spellings) is a type of pottery or porcelain with a metallic glaze that gives the effect of iridescence. It is produced by metallic oxides in an overglaze finish, which is given a second firing at a lower temperature in a "muffle kiln", or a reduction kiln, excluding oxygen. The discovery of this technique can be traced back to the 7th century A.D. when Islam emerged in the city of Mecca. Lusterware was first created for the royal courts and the technique of lusterware on ceramic was developed originally in Iraq. Some pieces were signed by their makers, this acted as an indication of the admiration towards each craftsman. Trading in the Middle East was very popular. Abbasid lusterware was very common in trade within the Islamic world; other popular trade items were textiles and various materials for building and crafting (ivory, wood, etc.). The Abbasid period served as an era of discovery especially in relation to the production of luster. The city of Baghdad, Iran and surrounding cities were located on the Silk Road which was the hub of trading during this period. There was a movement of goods generated between Iraq and China which triggered artistic emulations both ends, as well as some transfers of technologies, notably in the realm of ceramics. Lusterware traveled along the trade routes; the production of ceramic lusterware was seen in Egypt and Syria during later centuries.

Finale
Finale is the flagship program of a series of proprietary music notation software developed and released by MakeMusic for the Microsoft Windows and macOS operating systems. First released in 1988, version 26 was released in 2018. Finale has been regarded as one of the industry standards for music notation software. Finale is one of a number of types of software used by composers, songwriters and arrangers for creating sheet music, including the score for an entire ensemble (e.g., orchestra, concert band, big band, etc.) and parts for the individual musicians. A scorewriter is to music notation what a word processor is to text, in that they both allow fast corrections (via the "undo" button), flexible editing, easy sharing of content (via the Internet or compact storage media), and production of a clean, uniform layout. In addition, most scorewriters, including Finale, are able to use software-based synthesizers to "play" the sounds of the notated music and record the music—an especially useful feature for novice composers, when no musicians are readily available, or if a composer cannot afford to hire musicians. MakeMusic also offers several less expensive versions of Finale (currently available for Microsoft Windows only), which do not contain all of the main program's features. These include PrintMusic and a freeware program, Finale Notepad, which allows only rudimentary editing. Discontinued versions include Finale Guitar, Notepad Plus, Allegro, SongWriter, and the free Finale Reader.

Sex Differences in Humans
Sex differences in humans have been studied in a variety of fields. In humans, biological sex is determined by five factors present at birth: the presence or absence of a Y chromosome, the type of gonads, the sex hormones, the internal reproductive anatomy (such as the uterus), and the external genitalia. Genetic sex is determined solely by the presence or absence of a Y chromosome. A child's presumed sex is determined at birth by observation of the external genitalia. Sex differences generally refer to traits that are sexually dimorphic. A subset of such differences is hypothesized to be a product of the evolutionary process of sexual selection.

Actinopterygii
Actinopterygii (/ˌæktɪnɒptəˈrɪdʒiaɪ/; from actino- 'having rays', and grc πτέρυξ (ptérux) 'wing, fins'), members of which are known as ray-finned fishes, is a clade (traditionally class or subclass) of the bony fishes. They comprise over 50% of living vertebrate species. The ray-finned fishes are so-called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they comprise nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from Paedocypris, at 8 mm (0.3 in), to the massive ocean sunfish, at 2,300 kg (5,070 lb), and the long-bodied oarfish, at 11 m (36 ft). The vast majority of Actinopterygii (~95%) are teleosts.

Isatis tinctoria L. (Woad)
Isatis tinctoria L. (Brassicaceae), which is commonly known as woad, is a species with an ancient and well-documented history as an indigo dye and medicinal plant. Currently, I. tinctoria is utilized more often as medicinal remedy and also as a cosmetic ingredient. In 2011, I. tinctoria root was accepted in the official European phytotherapy by introducing its monograph in the European Pharmacopoeia. The biological properties of raw material have been known from Traditional Chinese Medicine (TCM). Over recent decades, I. tinctoria has been investigated both from a phytochemical and a biological point of view. The modern in vitro and in vivo scientific studies proved anti-inflammatory, anti-tumour, antimicrobial, antiviral, analgesic, and antioxidant activities. The phytochemical composition of I. tinctoria has been thoroughly investigated and the plant was proven to contain many valuable biologically active compounds, including several alkaloids, among which tryptanthrin, indirubin, indolinone, phenolic compounds, and polysaccharides as well as glucosinolates, carotenoids, volatile constituents, and fatty acids. This article provides a general botanical and ethnobotanical overview that summarizes the up-to-date knowledge on the phytochemistry and biological properties of this valuable plant in order to support its therapeutic potential. Moreover, the biotechnological studies on I. tinctoria, which mainly focused on hairy root cultures for the enhanced production of flavonoids and alkaloids as well as on the establishment of shoot cultures and micropropagation protocols, were reviewed. They provide input for future research prospects.

Conductive Heat Transfer in Thermal Bridges
A thermal bridge is a component of a building that is characterized by a higher thermal loss compared with its surroundings. Their accurate modeling is a key step in energy performance analysis due to the increased awareness of the importance of sustainable design. Thermal modeling in architecture and engineering is often not carried out volumetrically, thereby sacrificing accuracy for complex geometries, whereas numerical textbooks often give the finite element method in much higher generality than required, or only treat the case of uniform materials. Despite thermal modeling traditionally belonging exclusively to the engineer’s toolbox, computational and parametric design can often benefit from understanding the key steps of finite element thermal modeling, in order to inform a real-time design feedback loop. In this entry, these gaps are filled and the reader is introduced to all relevant physical and computational notions and methods necessary to understand and compute the stationary energy dissipation and thermal conductance of thermal bridges composed of materials in complex geometries. The overview is a self-contained and coherent expository, and both physically and mathematically as correct as possible, but intuitive and accessible to all audiences. Details for a typical example of an insulated I-beam thermal bridge are provided.

Flake Powder Metallurgy
Flake powder metallurgy (FPM) including different processing routes, conventional FPM (C-FPM), slurry blending (SB), shift-speed ball milling (SSBM), and high-shear pre-dispersion and SSBM (HSPD/SSBM). The name of FPM was derived from the use of flake metal powders obtained by low-speed ball milling (LSBM) from spherical powder. The uniformity of reinforcement distribution leads to increased strength and ductility. Powder is the basic unit in PM, especially advanced PM, and its control is key to various new PM technologies. The FPM is a typical method for finely controlling the powder shape through low-energy ball milling (LEBM) to realize the preparation of advanced material structures.
