Cracking of Wireless Networks
Cracking a wireless network is defeating the security of a wireless local-area network (back-jack wireless LAN). A commonly used wireless LAN is a Wi-Fi network. Wireless LANs have inherent security weaknesses from which wired networks are exempt. Wireless cracking is an information network attack similar to a direct intrusion. Two frequent types of vulnerabilities in wireless LANs are those caused by poor configuration, and those caused by weak or flawed security protocols.

Musical Instruments Made of Composites and Alternative Materials
The evolution of musical instrument manufacturing has been a dynamic process, with traditional materials such as wood playing a predominant role for centuries. However, the need for innovation in the musical industry has driven researchers and manufacturers to explore alternative materials that offer enhanced performance, sustainability, and versatility. The demand for different materials arises from various challenges faced by the musical instruments industry, including the lack of high-quality tonewoods, the significant variations in both mechanical and acoustical properties of wood internally within a single piece or across the same species, environmental concerns, and the quest for achieving specific acoustic properties. Composite materials, such as carbon- and graphite fiber-reinforced plastics (CFRPs and GFRPs), ceramic polymers, and nanocomposites, constitute promising alternatives that not only address these challenges, but also offer unique advantages in terms of durability, weight reduction, and customizable acoustic characteristics.

Usury
Usury (/ˈjuːʒəri/) is the practice of making unethical or immoral monetary loans that unfairly enrich the lender. The term may be used in a moral sense—condemning, taking advantage of others' misfortunes—or in a legal sense, where an interest rate is charged in excess of the maximum rate that is allowed by law. A loan may be considered usurious because of excessive or abusive interest rates or other factors defined by a nation's laws. Someone who practices usury can be called a usurer, but in contemporary English may be called a loan shark. In many historical societies including ancient Christian, Jewish, and many modern Islamic societies, usury meant the charging of interest of any kind and was considered wrong, or was made illegal. During the Sutra period in India (7th to 2nd centuries BC) there were laws prohibiting the highest castes from practicing usury. Similar condemnations are found in religious texts from Buddhism, Judaism (ribbit in Hebrew), Christianity, and Islam (riba in Arabic). At times, many nations from ancient Greece to ancient Rome have outlawed loans with any interest. Though the Roman Empire eventually allowed loans with carefully restricted interest rates, the Catholic Church in medieval Europe, as well as the Reformed Churches, regarded the charging of interest at any rate as sinful (as well as charging a fee for the use of money, such as at a bureau de change). Religious prohibitions on usury are predicated upon the belief that charging interest on a loan is a sin.

Targeted Therapeutic Sites for Non-Small Cell Lung Cancer
The advent of precision medicine has brought light to the treatment of non-small cell lung cancer (NSCLC), expanding the options for patients with advanced NSCLC by targeting therapy through genetic and epigenetic cues. Tumor driver genes in NSCLC patients have been uncovered one by one, including epidermal growth factor receptor (EGFR), mesenchymal lymphoma kinase (ALK), and receptor tyrosine kinase ROS proto-oncogene 1 (ROS1) mutants. Antibodies and inhibitors that target the critical gene-mediated signaling pathways that regulate tumor growth and development are anticipated to increase patient survival and quality of life. Targeted drugs continue to emerge, with as many as two dozen approved by the Food and Drug Administration (FDA), and chemotherapy and targeted therapy have significantly improved patient prognosis.

Forensic Photography
Forensic photography may refer to the visual documentation of different aspects that can be found at a crime scene. It may include the documentation of the crime scene, or physical evidence that is either found at a crime scene or already processed in a laboratory. Forensic photography differs from other variations of photography because crime scene photographers usually have a very specific purpose for capturing each image. As a result, the quality of forensic documentation may determine the result of an investigation, in that with the absence of good documentation, investigators may find it impossible to conclude what did or did not happen. Crime scenes can be major sources of physical evidence that is used to associate or link suspects to scenes, victims to scenes, and suspects to victims. Locard's exchange principle is a major concept that helps determine these relationships of evidence. It is the basic tenet of why crime scenes should be investigated. Anything found at a crime scene can be used as physical evidence as long as it is relevant to the case, which is why the documentation of a crime scene and physical evidence in its true form is key for the interpretation of the investigation. Knowing that crucial information for an investigation can be found at a crime scene, forensic photography is a form of documentation that is essential for retaining the quality of discovered physical evidence. Such physical evidence to be documented include those found at the crime scene, in the laboratory, or for the identification of suspects. All forensic photography must consider three elements at a crime scene: the subject, the scale, and a reference object. Also, the overall forensic photographs must be shown a neutral and accurate representation.

Void Nucleation in Metals
The research discussed about the development of micro-voids in metals, leading to ductile fracture, associated with plastic deformation, without taking into account the cleavage mechanism. Particular emphasis was placed on the results of observations and experimental studies, the characteristics of the phenomenon itself, without in-depth analysis in the field of widely used FEM modelling. The mechanism of void development as a fracture mechanism is presented. Observations of the nucleation of voids in metals from the turn of the 1950s and 1960s to the present day have been described. The nucleation mechanisms related to the defects of the crystal lattice as well as those resulting from the presence of second phase particles were characterised.

Way of the Five Pecks of Rice
The Way of the Five Pecks of Rice (Chinese: 五斗米道; pinyin: Wǔ Dǒu Mǐ Dào) or the Way of the Celestial Master, commonly abbreviated to simply The Celestial Masters, was a China Taoist movement founded by the first Celestial Master Zhang Daoling in 142 CE. At its height, the movement controlled a theocratic state in the Hanzhong valley, north of Sichuan. In 215 CE, the state was incorporated into Cao Cao's Kingdom of Wei, and the followers of the Celestial Master were dispersed all over China. The Celestial Masters believed that qi pervaded everything, and in order to achieve immortality, the correct balance of qi had to be present within the body. Having a poor quantity of qi in the body, would result in illness, and eventually death. Meditation could be used to restore qi to the body, but sex was to be avoided, as it could result in the loss of qi. If there was the correct balance of qi within the body upon death, an adherent could 'feign death' and be reborn. If not, an adherent would be transported to an earthly prison where he would face eternal torment. The Hanzhong state was divided into 24 regions which were led by an official. Each district had a civil register which recorded people's names and ranks. Three times a year, the registers were updated at the same time as an important feast. While a child's rank rose automatically, adults had to raise their own rank through religious achievement or marriage. Higher ranked people had more divine generals at their command, which could be used to fight demons that caused bad luck or disease. The state had a system of law that encouraged confession and benevolence rather than strict punishment. Criminals were asked to confess their crimes and meditate, and were given public work to do as a sentence. Few texts written by the Hanzhong Celestial Masters survive, with the most important being the Xiang'er commentary to the Dao De Jing. While the Hanzhong state lasted for only twenty-five years, their beliefs influenced all subsequent Daoist movements.

Aesthetic Education in Chinese Schools
Since the promulgation of the first school education regulations in the early 20th century, Chinese school aesthetic education has gone through its first century of history. Six stages of development have been formed in this century of vicissitudes, namely, the budding period, the starting period, the salvation movement period, the tortuous development period, the reconstruction period, and the modernization period of the new era. Aesthetic education in Chinese schools places a prominent place on “establishing, cultivating and clarifying morality”, emphasizes the role of “beauty” in “goodness”, and follows the aesthetic guideline of “unity of beauty and goodness”. Art education and its practical activities are the main content of school aesthetic education. The formation mechanism, laws, and characteristics of the sustainable development of school aesthetic education in China are summarized from the perspective of the century-old school aesthetic education policy, which is of theoretical guidance for the study of the future development of school aesthetic education in China.

Nonlocal Elasticity for Nanostructures: A Review of Recent Achievements
Recent developments in modeling and analysis of nanostructures are illustrated and discussed in this paper. Starting with the early theories of nonlocal elastic continua, a thorough investigation of continuum nano-mechanics is provided. Two-phase local/nonlocal models are shown as possible theories to recover consistency of the strain-driven purely integral theory, provided that the mixture parameter is not vanishing. Ground-breaking nonlocal methodologies based on the well-posed stress-driven formulation are shown and commented upon as effective strategies to capture scale-dependent mechanical behaviors. Static and dynamic problems of nanostructures are investigated, ranging from higher-order and curved nanobeams to nanoplates. Geometrically nonlinear problems of small-scale inflected structures undergoing large configuration changes are addressed in the framework of integral elasticity. Nonlocal methodologies for modeling and analysis of structural assemblages as well as of nanobeams laying on nanofoundations are illustrated along with benchmark applicative examples.

Dagor Dagorath
The Dagor Dagorath (Sindarin for Battle of Battles) is a fictional battle described in the legendarium of J. R. R. Tolkien. As Tolkien's works were conceived as a fictional "forgotten history" of the world, the Dagor Dagorath represents the coming End of the World, and is often referred to as simply "The End". As Tolkien originally wrote it, The Silmarillion ends with a prophecy by Mandos about the end of the world. The published Silmarillion ends instead with the last paragraph of Valaquenta. This was because Tolkien had abandoned the idea of the "second prophecy of Mandos", and the Valaquenta text, much later, contradicted it openly. However, references to the final battle remain in the published Silmarillion, such as a statement at the end of the Akallabêth that Ar-Pharazôn and his mortal warriors who had set foot on Aman were buried by falling hills, imprisoned in the Caves of the Forgotten until the "Last Battle and Day of Doom". Christopher Tolkien sees the account as similar to the Nordic legend of Ragnarök and J. R. R. Tolkien also made this connection in some of his letters.

Multiple-Output DC–DC Converters
Multiple-output DC–DC converters are essential in a multitude of applications where different DC output voltages are required. The interest and importance of this type of multiport configuration is also reflected in that many electronics manufacturers currently develop integrated solutions. Traditionally, the different output voltages required are obtained by means of a transformer with several windings, which are in addition to providing electrical isolation. However, the current trend in the development of multiple-output DC–DC converters follows general aspects, such as low losses, high-power density, and high efficiency, as well as the development of new architectures and control strategies.
