Gertrude Mitchell Carson Papers - Accession 1479 - M724 (780)
No full textThis collection consists of 11 letters on Winthrop Letterhead from Gertrude Mitchell (Carson) (1877-1928) to her cousin, Alice Mitchell of Richardsonville, S.C. (Saluda County) concerning her life as a student at Winthrop. Gertrude graduated from Winthrop College in 1900 with a B.A. degree in the Four-Year Normal Course (education). Also included is a Commencement program for the Class of 1897 and a Commencement Invitation for the Class of 1899. This collection is great resource for a glimpse into the life of a female college student in the late 1890s.https://digitalcommons.winthrop.edu/manuscriptcollection_findingaids/2458/thumbnail.jp

Longitudinally diode-pumped Nd: YAG double-clad planar waveguide laser
No full textWe report the demonstration of a near-diffraction-limited, compact, diode-end-pumped double-clad planar waveguide Nd:YAG laser. Efficient laser operation was achieved for the three dominant Nd3+ transitions at 1.064µm 0.946µm, and 1.32µm, with TE polarised output powers of 1.33W, 0.57W, and 0.33W for the available output couplers. The output beam from the monolithic plane-plane laser cavity had measured M2 values of 1.0 and 1.8, perpendicular and parallel to the plane of the waveguide respectively
15W diode-side-pumped Tm:YAG waveguide laser at 2µm
No full textThe high-power side-pumped operation of a double-clad Tm:YAG waveguide laser at 2.02µm, using two proximity-coupled 20W diode pump lasers, is reported. A slope efficiency of 43% was observed with respect to incident diode power, giving a maximum output power of 15W. The double-clad geometry ensures diffraction-limited output in the guided plane
Natural Variation of the Circadian Clock in Neurospora
No full textMost living organisms on earth experience daily and expected changes from the rotation of the earth. For an organism, the ability to predict and prepare for incoming stresses or resources is a very important skill for survival. This cellular process of measuring daily time of the day is collectively called the circadian clock. Because of its fundamental role in survival in nature, there is a great interest in studying the natural variation of the circadian clock. However, characterizing the genetic and molecular mechanisms underlying natural variation of circadian clocks remains a challenging task. In this chapter, we will summarize the progress in studying natural variation of the circadian clock in the successful eukaryotic model Neurospora, which led to discovering many design principles of the molecular mechanisms of the eukaryotic circadian clock. Despite the success of the system in revealing the molecular mechanisms of the circadian clock, Neurospora has not been utilized to extensively study natural variation. We will review the challenges that hindered the natural variation studies in Neurospora, and how they were overcome. We will also review the advantages of Neurospora for natural variation studies. Since Neurospora is the model fungal species for circadian study, it represents over 5 million species of fungi on earth. These fungi play important roles in ecosystems on earth, and as such Neurospora could serve as an important model for understanding the ecological role of natural variation in fungal circadian clocks.Advances in Genetics, Vol. 99

Towards the Holy Grail: combining system dynamics and discrete-event simulation in healthcare
No full textThe idea of combining discrete-event simulation and system dynamics has been a topic of debate in theoperations research community for over a decade. Many authors have considered the potential benefits ofsuch an approach from a methodological or practical standpoint. However, despite numerous examples ofmodels with both discrete and continuous parameters in the computer science and engineering literature,nobody in the OR field has yet succeeded in developing a genuinely hybrid approach which truly integratesthe philosophical approach and technical merits of both DES and SD in a single model. In this paperwe consider some of the reasons for this and describe two practical healthcare examples of combinedDES/SD models, which nevertheless fall short of the “holy grail” which has been so widely discussed inthe literature over the past decade
Continuous-wave and passively Q -switched cladding-pumped planar waveguide lasers
No full textGreater than 12W of average output power has been generated from a diode-pumped YbYAG cladding-pumped planar waveguide laser. The laser radiation developed is linearly polarized and diffraction limited in the guiding dimension. A slope efficiency of 0.5WW with a peak optical optical conversion efficiency of 0.31WW is achieved. In a related structure, greater than 8W of Q -switched average output power has been generated from a NdYAG cladding-pumped planar waveguide laser by incorporation of a Cr 4+ YAG passive Q switch monolithically into the waveguide structure. Pulse widths of 3ns and pulse-repetition frequencies as high as 80kHz have been demonstrated. A slope efficiency of 0.28WW with a peak optical optical conversion efficiency of 0.21WW is achieved
