Discriminating between Parallel, Anti-Parallel and Hybrid G-Quadruplexes
G-quadruplexes (G4) are now extensively recognised as a peculiar non-canonical DNA geometry that plays a prime importance role in processes of biological relevance whose number is increasing continuously. The same is true for the less-studied RNA G4 counterpart. G4s are stable structures; their geometrical parameters may be finely tuned not only by the presence of particular sequences of nucleotides but also by the salt content of the medium or by a small molecule that may act as a peculiar topology inducer.

Electromagnetic Vibrational Energy Harvesting Principles
As industries need more real-time monitoring and interconnected systems, the demand for wireless sensors expands. Vibrational energy harvesters are a potential solution for powering these sensors, as vibrations commonly exist where monitoring occurs. Developments in low-power circuitry have also led to the feasibility of these types of harvesters. Electromagnetic harvesters are a standout among various types of vibrational harvesters due to their ability to capture kinetic energy in a low-frequency range. This leads to these devices being more applicable in real-world applications where ambient vibrations are typical of having low frequencies.

Carbon Nanomaterials
Being a member of nanofamily, carbon nanomaterials exhibit specific properties that mostly arise from their small size. They have proved as very promising for the application in the technical and biomedical fields. A wide spectrum of use implies the inevitable presence of carbon nanomaterials in the environment, thus potentially endangering the whole nature. Although scientists worldwide have conducted researches investigating the impact of these materials, it is evident that there are still significant gaps concerning the knowledge of their mechanisms, as well as prolonged and chronic exposure and effects. Thinking small can greatly help us improve our lives, but also obliges us to deeply and comprehensively investigate all the possible consequences that could arise from our pure-hearted scientific ambitions and work.

Friction Stir Welding
Friction stir welding is a method of materials processing that enables the joining of similar and dissimilar materials. The process, as originally designed by The Welding Institute (TWI), provides a unique approach to manufacturing—where materials can be joined in many designs and still retain mechanical properties that are similar to, or greater than, other forms of welding. This process is not free of defects that can alter, limit, and occasionally render the resulting weld unusable.

Householder (Buddhism)
In English translations of Buddhist texts, householder denotes a variety of terms. Most broadly, it refers to any layperson, and most narrowly, to a wealthy and prestigious familial patriarch. In contemporary Buddhist communities, householder is often used synonymously with laity, or non-monastics. The Buddhist notion of householder is often contrasted with that of wandering ascetics (Pali: Pāḷi: samaṇa; Sanskrit: śramaṇa) and monastics (bhikkhu and bhikkhuni), who would not live (for extended periods) in a normal house and who would pursue freedom from attachments to houses and families. Upāsakas and upāsikās, also called śrāvakas and śrāvikās - are householders and other laypersons who take refuge in the Three Jewels (the Buddha, the teachings and the community) and practice the Five Precepts. In southeast Asian communities, lay disciples also give alms to monks on their daily rounds and observe weekly uposatha days. In Buddhist thought, the cultivation of ethical conduct and dāna or "almsgiving" will themselves refine consciousness to such a level that rebirth in one of the lower heavens is likely even if there is no further "Noble" Buddhist practice (connected with the Supramundane goal of Nibbana, "Unbinding"). This level of attainment is viewed as a proper aim for laypersons. In some traditional Buddhist societies, such as in Myanmar and Thailand, people transition between householder and monk and back to householder with regularity and celebration as in the practice of shinbyu among the Bamar people. One of the evolving features of Buddhism in the West is the increasing dissolution of the traditional distinction between monastics and laity.

Tiva-C LaunchPad
The Tiva-C (a.k.a. TM4C) LaunchPads are inexpensive self-contained, single-board microcontrollers, about the size of a credit card, featuring an ARM Cortex-M4F 32-bit CPU operating at 80 to 120 MHz, manufactured by Texas Instruments. The TM4C Series TM4C123G LaunchPad is an upgrade from TI's Stellaris LaunchPad adding support options for motion control PWMs and USB Host functionality. The more recently released TM4C1294 Connected LaunchPad is the first cloud-connected offering in TI's LaunchPad ecosystem and provides a solid foundation for beginning and evaluating embedded IoT designs. There are many I/O pins (40 to 80 depending upon version) that have multi-personality. This means that they can be easily configured as digital inputs or outputs, analog inputs and outputs or other functions, allowing a great variety of applications, are just the multiple serial ports have the ability to interface with more items such as test cards or other communication modules, etc. Among those pins there are included the GND and POWER (3.3 V) pins. The clock is 80 or 120 MHz (vers based), which makes them 5 to over 7 times faster than the Arduino Uno's 16 MHz ATmega328P microcontroller. As with any Cortex M4, the CPU has some DSP (digital signal processor) instructions, with some limitations. One can do signal processing, for example, sampling a human voice with a good quality, able to be processed in MATLAB. The CPU contains the optional floating-point unit with single-precision floating point operations supported. They have an additional USB port which can act as USB host, allowing the connection of multiple devices and the "Connected" one has an integrated 10/100 Ethernet MAC+PHY for Internet connectivity. They also have a temperature sensor and on-board LED(s) and RGB LED(s), which allows you to generate various colors by combining the three basic colors (red, blue and green) of the additive color synthesis. The Tiva/TM4C LaunchPads come preloaded with software to demonstrate many of the capabilities of the ARM microcontroller and with a quickstart application to get up and running within minutes.

Cell Lines from Strawberry Fruits
Fleshy fruits are crucial in a healthy human diet but highly perishable due to their delicate texture at full ripe stage. Tomato and strawberry are leading crops which belongs to this fleshy fruit category, as well as models for ripening of climacteric and non-climateric fruits, respectively. In this regard, cell cultures derived from strawberry fruit at different developmental stages have been obtained to evaluate their potential use to study different aspects of strawberry ripening. Callus from leaf and cortical tissue of unripe-green, white, and mature-red strawberry fruits were induced in a medium supplemented with 11.3 M 2,4-dichlorophenoxyacetic acid (2,4-D) under darkness. This 2,4-D chemical reagent is an herbicide which mimics the action of the natural plant hormone auxin, widely used in plant cell culture. The transfer of the established callus from darkness to light induced the production of anthocyanin. The replacement of 2,4-D by abscisic acid (ABA) noticeably increased anthocyanin accumulation in green-fruit callus. Cell walls were isolated from the different fruit cell lines and from fruit receptacles at equivalent developmental stages and sequentially fractionated to obtain fractions enriched in soluble pectins, ester bound pectins, xyloglucans (XG), and matrix glycans tightly associated with cellulose microfibrils. These fractions were analyzed by cell wall carbohydrate microarrays. In fruit receptacle samples, pectins were abundant in all fractions, including those enriched in matrix glycans. The amount of pectin increased from green to white stage, and later these carbohydrates were solubilized in red fruit. Apparently, XG content was similar in white and red fruit, but the proportion of galactosylated XG increased in red fruit. Cell wall fractions from callus cultures were enriched in extensin and displayed a minor amount of pectins. Stronger signals of extensin antibodies were detected in sodium carbonate fraction, suggesting that these proteins could be linked to pectins. Overall, the results obtained suggest that fruit cell lines could be used to analyze hormonal regulation of color development in strawberry but that the cell wall remodelling process associated with fruit softening might be masked by the high presence of extensin in callus cultures.

Vascular Endothelial Dysfunction-Related Disease
Oxidative stress and chronic inflammation play an important role in the pathogenesis of atherosclerosis. Atherosclerosis develops as the first step of vascular endothelial dysfunction induced by complex molecular mechanisms. Vascular endothelial dysfunction leads to oxidative stress and inflammation of vessel walls, which in turn enhances vascular endothelial dysfunction. Vascular endothelial dysfunction and vascular wall oxidative stress and chronic inflammation make a vicious cycle that leads to the development of atherosclerosis.
