Devil's Garden (Grand Staircase-Escalante National Monument)
The Devil's Garden of the Grand Staircase-Escalante National Monument (GSENM) in south central Utah, the United States, is a protected area featuring hoodoos, natural arches and other sandstone formations. The United States Geological Survey (USGS) designated the name Devils Garden—without an apostrophe according to USGS naming conventions—on December 31, 1979. The area is also known as the Devils Garden Outstanding Natural Area within the National Landscape Conservation System. The formations in the Devils Garden were created, and continue to be shaped, by various weathering and erosional processes. These natural processes have been shaping sandstone layers formed more than 166 million years ago during the Jurassic period's Middle epoch. The Bureau of Land Management (BLM) administers the Devils Garden and the entire GSENM which is the first national monument assigned to the BLM.

Inversion (Meteorology)
In meteorology, an inversion is a deviation from the normal change of an atmospheric property with altitude. It almost always refers to an inversion of the air temperature lapse rate, in which case it is called a temperature inversion. Normally, air temperature decreases with an increase in altitude, but during an inversion warmer air is held above cooler air. An inversion traps air pollution, such as smog, close to the ground. An inversion can also suppress convection by acting as a "cap". If this cap is broken for any of several reasons, convection of any moisture present can then erupt into violent thunderstorms. Temperature inversion can notoriously result in freezing rain in cold climates.

Organophosphate Esters in Aquatic Environment
Organophosphate esters (OPEs) are increasingly used as flame retardants and plasticizers in various products. Most of them are physically mixed rather than chemical bonded to the polymeric products, leading to OPEs being readily released into the surrounding environment. Due to their relatively high solubility and mobility, OPEs are ubiquitous in the aquatic environment and may pose potential hazards to human health and aquatic organisms.

Karate Women’s Embodied Subjectivities
Karate can be both a martial art and a combat sport. Male and female karate athletes attended the Tokyo Olympic Games 2020 (2021). Elite sport often portrays female athletes through the sexualization of their bodies, while the martial environment leaves them open to accusations of masculinization. In the process of constructing themselves as fighters, karateka women do produce new ways of performing femininities and masculinities, which is a hard-work process of negotiations, leading them to the construction of a particular habitus strictly linked to their performativity within the environment. They take part in a contested terrain that mixes several elements that are often contrasting.

Anti-Cancer Potential of Cinnamaldehyde
Cinnamaldehyde has anti-cancer effects through a number of different mechanisms that are interconnected with one another. These effects reduce some of the most severe symptoms of abnormally rapid cell growth. Some of the mechanistic approaches include the induction of apoptosis, cell cycle arrest, interruption in angiogenesis, free radical scavenging, inhibition of inflammation, and interference with cellular invasion and metastasis. According to the types, doses and duration of treatment of cancer, the mechanisms involved could change.

Human Papillomavirus Oncoproteins and Ubiquitin Proteasome System
Papillomaviridae is a diverse family of small, non-enveloped DNA viruses, approximately 50–60 nm in diameter that infect all homoeothermic vertebrates including humans. Human papillomavirus (HPV) E6 and E7 oncoproteins are critical for development and maintenance of the malignant phenotype in HPV-induced cancers. These two viral oncoproteins interfere with a plethora of cellular pathways, including the regulation of cell cycle and the control of apoptosis, which are critical in maintaining normal cellular functions. E6 and E7 bind directly with certain components of the Ubiquitin Proteasome System (UPS), enabling them to manipulate a number of important cellular pathways.

Vertebral Fractures in HIV-Infected Patients
HIV-infected patients show high risk of fracture. The aims of our study were to determine the prevalence of vertebral fractures (VFs) and their associations with vitamin D in HIV patients. 100 patients with HIV infection and 100 healthy age- and sex-matched controls were studied. Bone mineral density was measured by quantitative ultrasound at the non-dominant heel. Serum osteocalcin and C-terminal telopeptide of collagen type 1 served as bone turnover markers. Bone ultrasound measurements were significantly lower in patients compared with controls (Stiffness Index (SI): 80.58 ± 19.95% vs. 93.80 ± 7.10%, respectively, p < 0.001). VFs were found in 16 patients and in 2 controls. HIV patients with vertebral fractures showed lower stiffness index (SI) (70.75 ± 10.63 vs. 83.36 ± 16.19, respectively, p = 0.045) and lower vitamin D levels (16.20 ± 5.62 vs. 28.14 ± 11.94, respectively, p < 0.02). The majority of VFs (87.5%) were observed in HIV-infected patients with vitamin D insufficiency, and regression analysis showed that vitamin D insufficiency was significantly associated with vertebral fractures (OR 9.15; 95% CI 0.18–0.52, p < 0.04). VFs and are a frequent occurrence in HIV-infected patients and may be associated with vitamin D insufficiency.

Semantic Search and SemSime
This paper presents SemSime, a semantic similarity method for searching over a setof digital resources previously annotated by means of concepts from a weighted reference ontology.It is based on a frequency approach for weighting the ontology, and refines both the user request and the annotations of the digital resources with rating scores. Such scores are High, Medium, and Low and, in the user request, indicate the preferences assigned by the user to each of the concepts representing the searching criteria whereas, in the annotations of the digital resources, they represent the levels of quality associated with each concept in describing the resources. The experiment we have performed shows that SemSime outperforms the previous semantic search method SemSim.
