Mammalian female reproduction requires preovulatory surges of gonadotropin-releasing hormone (GnRH) from neurons in the preoptic area (POA) of the hypothalamus, initiated by elevated estradiol (E₂). Rising E₂ activates a subset ofsexually dimorphic Kisspeptin neurons in the female, located in the anteroventralperiventricular nuclei (AVPV). Conversely, E₂ negative feedback is mediated by...

Ovulation requires preovulatory surges of gonadotropin-releasing hormone (GnRH) from preoptic hypothalamic neurons, initiated by elevated ovarian estradiol (E₂). Rising estradiol activates a subset of sexually dimorphic kisspeptin (Kiss-1) neurons in the female, located in the anteroventral periventricular nuclei (AVPV). Conversely, estradiol negative feedback on GnRH secretion is mediated by a...

The story of Leo Szilard has not been told in its full complexity. This is especially so of the role imagination played in Szilard’s worldview. Szilard, like many other scientists in the mid-twentieth century, worked on the Manhattan Project. Like these other wartime participants, the work and relationships formed during...
These essays are an attempt to rebuild memories that explore the nature of work and family. They explore how work knocks against the joints of the body and against the joints between family members, and, as time passes, how the next generation inherits the family line of work only to...
Affective reactions to daily stressors are known mechanisms through which daily stressors impact health and well-being (e.g., Charles et al., 2013; Piazza et al., 2013; Sin et al., 2015; Stawski et al., 2019). Therefore, understanding what may promote resilience or vulnerability to such affective reactions is imperative. Theoretical perspectives (Almeida,...
Daily social stressors are important everyday experiences that influence an individual’s daily health and well-being across the lifespan. One pathway through which daily social stressors influence health and well-being is through changes in positive and negative affect. The vast majority of previous research has focused on individual difference characteristics to...
This paper deals with finite abstract Witt rings in the case where
-1 = 1 in the square class group.
The results also apply to Witt rings
of quadratic forms over fields where √-1
is in the field.
The concept
of relative rigidity is studied in finite abstract Witt rings...
Artificial lipid bilayer technologies are effective models for studying cell membrane properties. Droplet bilayers rely on microfluidics and provide advantages over other bilayer methods due to their compatibility with automated development systems that increase yield while minimizing cost. This paper describes the implementation of bilayer technologies using membrane protein channels...
Over the last 60 years, supplemental strength and conditioning for improving sport performance has gone from being nearly non-existent to a cornerstone feature of elite collegiate, amateur, and professional athletics. Concurrent with this profession-related evolution, technologies for monitoring and tracking physical performance have become more prevalent and useful. As an...
Ian Angell, in the New Barbarian Manifesto, said “A ‘brave new world’ is being forced upon unsuspecting societies by advances in information technology.” It would seem then, that technological advances happen automatically and have a life of their own. There is a logic to technological advancements that is outside human...
People involved in a nuclear activity, whether they are developing it, benefiting from it, or opposing it, see inherent connections between various aspects of nuclear science and technology. This thesis investigates three nuclear sites: a university research reactor, a dual-purpose reactor that produced plutonium for the U.S. military and electricity...
The atomic age was enacted by many scientists as a way to realize health and human rights. Human rights were conceived in this context as rights to economic development, science education, and nuclear medicine. The United States Atomic Energy Commission (AEC) acted hand in hand with UN agencies and educators...
Beginning in the late-nineteenth century, several dialogues emerged concerning life on Mars. Some supported the notion of an inhabited Mars, citing recent observations of the planet, while others, pointing to a lack of concrete evidence, denied the validity of such a bold hypothesis. The dialogues within and between different...
The Second World War was not just a military struggle but also a struggle between two different agriculture, food distribution, and nutrition systems in the United Kingdom and Nazi Germany. At the start of the war, both countries understood that food and nutrition would play an important role and carefully...
In 1947, scientists from the University of California departed for a fifteen-month expedition to Africa. Jessie Camp, wife of the head paleontologist Dr. Charles L. Camp, had no official position on the expedition. Yet in performing her traditional domestic duties, she greatly contributed to the overall success of the expedition....
The Hanford Nuclear Reservation drew public ire during the 1980s and 1990s when activist groups forced the declassification of 19,000 documents and discovered proof of accidental and intentional releases of radioactive materials into the environment. These releases had been kept from the public. Although many locals had for decades wondered...
