- Description:
- Living organisms undergo morphogenesis as they develop and change shape to fit their evolved niche in natural ecosystems. The biological processes underlying morphogenesis involve sophisticated feedback loops between spatiotemporal release of morphogenic molecules that diffuse and signal cell differentiation, as well as contextual interaction with the physical surroundings of the...

- Description:
- Subchalcogenides are rare compounds that have both metal-metal and metal-chalcogenide (sulfur, selenium, tellurium) interactions. Unlike conventional semiconductors, the metals do not obey the so-called 8-N octet rule for oxidation states, often resulting in low or zero valent metal atoms. The presence of both metal-metal and metal-chalcogenide bonding can also lead...

- This dissertation offers a novel interpretation of Aristotle’s notion of teaching (didaskalia). In Part I, I defend my claim that we can find in Aristotle’s works a conception of teaching, which is a crucial yet under-explored part of his theory of education. In Part II, I use this interpretation to...

- Description:
- The staggered (or imbricated) lamellar ``brick-and-mortar" nanostructure of nacre endows nacre with strength and fracture toughness values exceeding by an order of magnitude those of the constituents, and inspires the advent of new robust biomimetic materials. While many deterministic studies clarified these advantageous features in the mean sense, a closed-form...

- Description:
- The mammalian retina contains three classes of photoreceptors: rods, cones and the recently discovered intrinsically photosensitive retinal ganglion cells (ipRGCs). ipRGCs express the photopigment melanopsin and were initially thought to be a homogeneous population of cells that drive subconscious visual behaviors such as circadian photoentrainment and pupil constriction. However, recent...

- This study is a response to the observation that people articulate meanings of rules in flexible and context-specific ways, but that literature on international legal, norm-based, strategic-logical, and ethical/moral rules typically treats them as pregiven, stable objects. By examining people’s evolving justifications of practices related to firefighting (protecting against and...

LM cells can be separated into three molecularly and functionally distinct cell populations based on the expression pattern of CD34 and CD49b: stem (LSC, CD34+/CD49b+), intermediate (LIC, CD34+/CD49b-), and differentiated cells (LDC, CD34-/CD49b-). Progesterone via progesterone receptor (PR/PGR)...
