3D Cell Cultures
The 3D cell cultures allow cells to growth and interact between them and with the extracellular matrix in three dimensions. This conforms a culture structure closer to physiological conditions than the cell monolayers (2D) traditionally employed in cell biology, and it can be achieved by using extracellular matrix hydrogels derived from decellularized tissues, bio-printed scaffolds made of different materials, or by forcing the cells to interact between each other without physical support. 3D culture models provide a powerful tool to understand cell-to-cell interactions when used in co-cultures, and to determine the involvement of extracellular vesicles as major key interactors in cellular crosstalk.

Local Strong Sandstorms
The local strong sandstorms (LSS), similar to haboobs in Sahara and the North America, often occur suddenly, in tens of minutes during the late afternoon, and before dusk in deserts in China, causing a significant impact on the local atmospheric environment. The Sudan haboob or American haboob often appears in the wet season, followed by thunderstorm events. In contrast, the LSS in China appears most frequently in relatively dry season. The lack of observational data in weather conditions before their formation, during their development and after their disappearance have hindered our understanding of the evolution mechanism of LSS/haboobs.

Meloidogyne graminicola
Rice (Oryza sativa L.) is one of the main cultivated crops worldwide and represents a staple food for more than half of the world population. Root-knot nematodes (RKNs), Meloidogyne spp., and particularly M. graminicola, are serious pests of rice, being, probably, the most economically important plant-parasitic nematode in this crop. M. graminicola is an obligate sedentary endoparasite adapted to flooded conditions. Until recently, M. graminicola was present mainly in irrigated rice fields in Asia, parts of the Americas, and South Africa. However, in July 2016, it was found in Europe, in northern Italy in the Piedmont region and in May 2018 in the Lombardy region in the province of Pavia.

E-Commerce in Agri-Food Sector
Agricultural e-commerce (AE) has attracted substantial attention within various research disciplines for several years. In this paper, we present a literature review of the recent state of AE research published from 2000 through to 2021 in 83 journals. Based on Service-Dominant Logic (S-D logic) and Qualitative Comparative Analysis (QCA), we identify six research themes, and a theoretical continuum is applied to reveal how research themes and scholarly approaches fit into the S-D logic framework. A general increasing trend in the number of articles confirms the escalating interest in AE research; however, different themes perform unevenly with S-D logic. Even though research themes such as Consumer Willingness are getting closer to S-D logic premises, and ideologies that are increasingly approaching S-D logic have been applied to analyzing AE topics, unfortunately, there remains a paucity of papers that wield S-D logic in the AE field. Our research focuses on an innovative emerging AE field and, simultaneously, provides an approach of integrating S-D logic into analyzing academic papers in the AE domain. This research may shed some light on future possibilities that S-D logic could support the co-creation of value between consumers and agribusiness managers, and other broader disciplines such as management and marketing.

Fibroblast Growth Factor 23 and Osteoporosis
Osteoporosis is a chronic debilitating disease caused by imbalanced bone remodeling processes that impair the structural integrity of bone. Over the last ten years, the association between fibroblast growth factor 23 (FGF23) and osteoporosis has been studied in both pre-clinical and clinical investigations. FGF23 is a bone-derived endocrine factor that regulates mineral homeostasis via the fibroblast growth factor receptors (FGFRs)/αKlotho complex. These receptors are expressed in kidney and the parathyroid gland. Preclinical studies have supported the link between the local actions of FGF23 on the bone remodeling processes. In addition, clinical evidence regarding the effects of FGF23 on bone mass and fragility fractures suggest potential diagnostic and prognostic applications of FGF23 in clinical contexts, particularly in elderly and patients with chronic kidney disease. However, inconsistent findings exist and there are areas of uncertainty requiring exploration.

Mechanisms of Cathepsins in Hepatocellular Carcinoma
Cathepsins are lysosomal proteases that are essential to maintain cellular physiological homeostasis and are involved in multiple processes, such as immune and energy regulation. Cathepsins are also involved in pathological situations, especially when they are secreted and enter the extracellular space. Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer and it is the third leading cause of cancer-related deaths worldwide. Cathepsins are involved in the pathology of HCC through acting in proliferation, apoptosis, angiogenesis, invasion and metastasis, metabolism and immunity.

Supplemental Security Income
Supplemental Security Income (SSI) is a United States means-tested tax payer funded program that provides cash payments to individuals residing in the United States who have paid into social security and are eligible to retire. This is not SSD. SSI was created by the Social Security Amendments of 1972 and is incorporated in Title 16 of the Social Security Act. The program began operations in 1974. SSI was created to replace federal-state adult assistance programs that served the same purpose, but were administered by the state agencies and received criticism for lacking consistent eligibility criteria. The restructuring of these programs was intended to standardize the eligibility requirements and level of benefits. Although administered by the Social Security Administration, SSI is funded from the U.S. Treasury general funds, not the Social Security trust fund. Today, the program provides benefits to approximately eight million Americans.

Dago Dazzler
A dago dazzler is an elaborately decorated document used to identify its bearer, usually an academic, as someone with an official association with an institution, usually a university or college, with the purpose of impressing low-level bureaucrats, usually of a foreign nation, so that they will allow the bearer to gain access to archived material or to perform some other action. The document is given more than the usual amount of decoration—often with colored ribbons and shiny seals—solely for the purpose of impressing bureaucrats. The term, used by academics and sometimes by government officials, is meant to disparage the bureaucrats, who are usually located in another country. The first word (dago) is an ethnic slur for Italians (and sometimes Spaniards and Latin Americans), but dago dazzlers have been used in other countries, including China . Dago dazzlers were created as early as the late 19th century in the United States , but examples have been referred to in recent decades. Published references nowadays are often accompanied by a statement by the writer that the word "dago" in the term is an ethnic slur.

Lossy Mode Resonance-Based Fiber Optic Sensors
Fiber optic sensors (FOSs) based on the lossy mode resonance (LMR) technique have gained substantial attention from the scientific community. The LMR technique displays several important features over the conventional surface plasmon resonance (SPR) phenomenon, for planning extremely sensitive FOSs. Unlike SPR, which mainly utilizes the thin film of metals, a wide range of materials such as conducting metal oxides and polymers support LMR.

Electrochemical RAM
Electrochemical Random-Access Memory (ECRAM) is a type of non-volatile memory (NVM) with multiple levels per cell (MLC) designed for deep learning analog acceleration. An ECRAM cell is a three-terminal device composed of a conductive channel, an insulating electrolyte, an ionic reservoir, and metal contacts. The resistance of the channel is modulated by ionic exchange at the interface between the channel and the electrolyte upon application of an electric field. The charge-transfer process allows both for state retention in the absence of applied power, and for programming of multiple distinct levels, both differentiating ECRAM operation from that of a field-effect transistor (FET). The write operation is deterministic and can result in symmetrical potentiation and depression, making ECRAM arrays attractive for acting as artificial synaptic weights in physical implementations of artificial neural networks (ANN). The technological challenges include open circuit potential (OCP) and semiconductor foundry compatibility associated with energy materials. Universities, government laboratories, and corporate research teams have contributed to the development of ECRAM for analog computing. Notably, Sandia National Laboratories designed a lithium-based cell inspired by solid-state battery materials, Stanford University built an organic proton-based cell, and International Business Machines (IBM) demonstrated in-memory selector-free parallel programming for a logistic regression task in an array of metal-oxide ECRAM designed for insertion in the back end of line (BEOL). In 2022, researchers at Massachusetts Institute of Technology built an inorganic, CMOS-compatible protonic technology that achieved near-ideal modulation characteristics using nanosecond fast pulses

Role of Macrophages in Tendon-Bone Healing
Tendon-bone healing comprises three stages: the inflammatory stage, the repair stage, and the remodeling stage. Macrophages appear in substantial populations in the early stages of tendon-bone healing and persist throughout the healing process, regulating cell proliferation, differentiation, and extracellular matrix formation by secreting various inflammatory factors and growth factors. The importance of macrophages in tendon-bone healing has been progressively emphasized in recent years, and the processes by which they affect tendon-bone healing have gradually been uncovered.

Cardioprotective Role of Vascular Endothelial Growth Factor B
Coronary heart disease (CHD) is the leading cause of death around the world. Based on the roles of vascular endothelial growth factor (VEGF) family members to regulate blood and lymphatic vessels and metabolic functions, several therapeutic approaches have been attempted. However proangiogenic therapies based on classical VEGF-A have been disappointing. Therefore, it has become important to focus on other VEGFs, like VEGF-B, which is a novel member of the VEGF family.

Self-Supervised Learning (SSL) in Deep Learning Contexts
Self-supervised learning (SSL) is a potential deep learning (DL) technique that uses massive volumes of unlabeled data to train neural networks. SSL techniques have evolved in response to the poor classification performance of conventional and even modern machine learning (ML) and DL models of enormous unlabeled data produced periodically in different disciplines. However, the literature does not fully address SSL’s practicalities and workabilities necessary for industrial engineering and medicine. Accordingly, this thorough review is administered to identify these prominent possibilities for prediction, focusing on industrial and medical fields. This extensive survey, with its pivotal outcomes, could support industrial engineers and medical personnel in efficiently predicting machinery faults and patients’ ailments without referring to traditional numerical models that require massive computational budgets, time, storage, and effort for data annotation.

Climate-Change Impact on Florida’s Water Resources
Emerging changes in water availability in the U.S. state of Florida have been recognized as a combined result of human perturbations, natural variability, and climate change. Florida is particularly susceptible to the impacts of the sea level rise due to its extensive coastline, low elevation, and lack of topographic relief to promote drainage. Owing to the porous nature of the state’s aquifer systems, saltwater intrusion into coastal areas is an evolving threat. Additionally, anthropogenic intervention has increased the contribution of nutrients and sediments to many lakes, reservoirs, and rivers, subsequently causing eutrophication and sedimentation problems.
