The California State University is a public university system in California. Composed of 23 campuses and eight off-campus centers enrolling 437,000 students with 44,000 faculty members and staff, CSU is the largest four-year public university system in the United States. It is one of three public higher education systems in the state, with the other two being the University of California system and the California Community College system. The CSU System is incorporated as The Trustees of the California State University. The California State University system headquarters are at 401 Golden Shore in Long Beach, California.The California State University was created in 1960 under the California Master Plan for Higher Education, and it is a direct descendant of the system of California State Normal Schools. With nearly 100,000 graduates annually, the CSU is the country's greatest producer of bachelor's degrees. The university system collectively sustains more than 150,000 jobs within the state, and its related expenditures reach more than $17 billion annually.In the 2011-12 academic year, CSU awarded 52 percent of newly issued California teaching credentials, 47 percent of the state's engineering degrees, 28 percent of the state's information technology bachelor's degrees, and it had more graduates in business , agriculture , communication studies, health , education, and public administration than all other universities and colleges in California combined. Altogether, about half of the bachelor's degrees, one-third of the master's degrees, and nearly two percent of the doctoral degrees awarded annually in California are from the CSU.Furthermore, the CSU is one of the top teachers in the United States of graduates who move on to earn their Ph.D. degrees in a related field. Since 1961, nearly three million alumni have received their bachelor's, master's, or doctoral degrees from the CSU system. CSU offers more than 1,800 degree programs in some 240 subject areas.

A magnetic memory bit structure using voltage-controlled magnetic anisotropy (VCMA) for switching the state of at least one magnetic free layer (FL) is configured for inducing strain to achieve very large VCMA coefficients, toward reducing the electric field potential and/or voltage required for switching the state of the magnetic free layer (FL). The disclosed apparatus and method increases voltage-controlled magnetic anisotropy (VCMA) efficiency, which is the change of interfacial magnetic anisotropy energy per unit electric field, thus exploiting strain engineering in designing next generation MeRAM devices which operate more efficiently with lower switching thresholds.

Northridge dentists, Dr. Michel Elyson and Dr. Ramin Assili, announce that they are now offering treatments for sleep apnea and TMJ at their office. TMJ, or temporomandibular joint disorder, has long been treated at dental offices. Sleep apnea, specifically the obstructive type, is increasingly being treated at dental offices with newly developed procedures and appliances. With treatment, patients with these conditions can gain greater quality of life and reduce their health risks. Dental treatments for TMJ and sleep apnea are numerous. TMJ, characterized by jaw joint pain and debility, may be treated with oral appliances, medications, or surgery, depending on its cause and severity. Obstructive sleep apnea symptoms include frequent awakenings during sleep, daytime fatigue, and breathlessness during routine activities. Dental treatments for sleep apnea include oral appliances, which help keep the jaw and tongue from collapsing backwards and blocking the airway during sleep. Soft tissue surgery, another dental sleep apnea treatment, involves removing excess tissue from the airway to reduce risks of airway collapse during sleep. The office of Dr. Elyson and Dr. Assili offers many dental treatments in several specialties. General dental care is available, which includes routine exams and cleanings. Several restorations, such as tooth-colored fillings, dental implants and bridges, are also performed. The office provides a full range of cosmetic dentistry, including teeth whitening, porcelain veneers and smile makeovers. Patients can also receive orthodontic care with Invisalign and other appliances. The office provides sedation dentistry options for eligible patients, and welcomes children from an early age. Treatments are performed using the latest technology, including laser dentistry. Dr. Assili and Dr. Elyson both earned their undergraduate degrees from California State University, Northridge, with Dr. Assili majoring in Biochemistry and Dr. Elyson majoring in Chemistry. The dentists also both attended UCLA School of Dentistry, where they earned their DDS degrees. The dentists have continued their studies during their careers by completing many hours of postgraduate training in topics such as dental implants. Dr. Elyson and Dr. Assili are both reputable members of the American Dental Association, the California Dental Association, and several other organizations in their profession.

Northridge dentist, Dr. Assili, and Dr. Elyson announce that they are now offering several promotions for a limited time this spring. Currently, patients can get a dental implant for $999, or $200 off any dental implant procedure. Invisalign treatment is being offered for just $3,395, including a complimentary consultation. The dentists are also offering a one-hour session of Zoom whitening for $199. None of these offers can be combined with any others, and all of the offers expire on June 30, 2017. Dental implants easily beat other tooth replacements in terms of appearance, oral health, and durability. Unlike dentures and bridges, dental implants have no external hardware to distinguish them from natural teeth. Implants also help keep the jaws from deteriorating after tooth loss, are easy to clean, and can last for life if cared for properly. Invisalign is the leading discreet orthodontic treatment and can often straighten the teeth of eligible patients more quickly than metal braces can. Zoom whitening uses three bleaching cycles per session, as well as a patented gel and activation light to maximize stain elimination. Many other treatments are also available at this office near CSU Northridge. For example, the dentists offer general dentistry, including routine exams, X-rays, cleanings, root canals, and extractions. Restorations at the office include tooth-colored fillings, bonding, and bridges. Cosmetic treatments at the office, such as crowns and veneers, are available to improve the smile in virtually every way. Smile makeovers are available to patients who want to improve their smile in multiple ways. The office also provides sedation dentistry, children's dentistry, and treatments for sleep apnea and TMJ. Dr. Assili and Dr. Elyson are both graduates of California State University, Northridge, where Dr. Assili earned his undergraduate degree in Biochemistry and Dr. Elyson earned his degree in Chemistry. After graduating from CSUN, the dentists earned their DDS degrees at UCLA School of Dentistry. During their careers, both dentists have completed additional training in specialties such as dental implants. Dr. Assili and Dr. Elyson are reputable members of the American Dental Association, the California Dental Association, and several other organizations in their profession.

Recent data indicate that cell cycle transcription in many alpha-Proteobacteria is executed by at least three conserved functional modules in which pairs of antagonistic regulators act jointly, rather than in isolation, to control transcription in S-, G2- or G1-phase. Inactivation of module components often results in pleiotropic defects, ranging from cell death and impaired cell division to fairly benign deficiencies in motility. Expression of module components can follow systemic (cell cycle) or external (nutritional/cell density) cues and may be implemented by auto-regulation, ancillary regulators or other (unknown) mechanisms. Here, we highlight the recent progress in understanding the molecular events and the genetic relationships of the module components in environmental, pathogenic and/or symbiotic alpha-proteobacterial genera. Additionally, we take advantage of the recent genome-wide transcriptional analyses performed in the model alpha-Proteobacterium Caulobacter crescentus to illustrate the complexity of the interactions of the global regulators at selected cell cycle-regulated promoters and we detail the consequences of (mis-)expression when the regulators are absent. This review thus provides the first detailed mechanistic framework for understanding orthologous operational principles acting on cell cycle-regulated promoters in other alpha-Proteobacteria. © FEMS 2015.

Conspectus Over the last to decades, radical chemistry of propargyl systems as developed into a potent synthetic field providing access to classes of organic compounds that are otherise hardly accessible. The levels of diastereoselection thus achieved (up to 100%) are unprecedented for free propargyl radicals, as ell as for organic radicals π-bonded to transition metals. These advances ere enabled by the coordination of the triple bond to a Co2(CO)6 core that precluded an acetylene-allene rearrangement, stabilized requisite propargyl cations, created conformational constraints at the carbon-carbon bond formation site, configurationally altered the acetylenic moiety alloing for 1,3-steric induction upon the nely formed stereocenters, increased bulkiness of propargyl triads thus controlling the spatial orientation of converging radicals, and alloed for α-to-γ projection of the reaction site and alteration of the transiency of radical intermediates.In the course of these studies, a number of popular beliefs ere proven to be untrue. First, cobalt-complexed propargyl cations, hich have long been considered to be thermally labile species, ere engaged in synthetically meaningful transformation at temperatures as high as 147 °C. Second, in radical dimerization reactions, higher reaction temperatures did not adversely impact the yields and levels of d,l-diastereoselectivity. Third, π-bonded organometallic radicals, deemed unruly, ere effectively controlled ith complementary mechanistic tools, thus achieving the highest levels of stereoselectivity (up to 100%) in inter- and intramolecular reactions. Fourth, meso stereoisomers, being thermally labile and kinetically disfavored, ere discovered to be major products in intramolecular cyclizations induced by cobaltocene. Fifth, propargyl cations ere synthesized in the absence of strong acids, thus increasing the functional tolerance and achieving a long sought after compatibility ith acid-sensitive functionalities. A concept of sequestered propargyl radicals as introduced to explain disparity in diastereoselectivity data: heterogeneous reducing agents allegedly produce free radicals, hile homogeneous reductants generate sequestered radicals associated ith reductant-derived oxidized species. Among mechanistic tools, a 1,3-steric induction as found to be most efficient for controlling the stereoselectivity of radical reactions (up to 100% d,l). In intramolecular reactions, a d,l-to-meso reversal of stereoselectivity as discovered ith zinc being replaced ith cobaltocene as a reductant. Among efficient tools for controlling the stereoselectivity in intramolecular cyclizations is a rigidity of the carbon tether that provides for an exclusive formation of d,l-diastereomers.To novel reactions that belong to a ne field of unorthodox organometallic radical chemistry ere discovered: the spontaneous conversion of cobalt-complexed propargyl cations to radicals and the THF-mediated process herein a THF molecule assumes a ne role of an initiator in radical reactions. A multistep mechanism involves a THF-induced alteration of propargyl cations that facilitates a redox process beteen metal clusters. Novel stereoselective methods provide access to topologically and functionally diverse 3,4-diaryl and 3,4-dialkyl-1,5-alkadiynes, 3,4-disubstituted 1,5-cycloalkadiynes (C8-C12), 3,4-dialkoxy-1,5-(cyclo)alkadiynes, and 3,7-diene-1,9-alkadiynes, hich can be used in targeted syntheses of organic assemblies of relevance to medicinal chemistry, materials science, and natural product syntheses. Novel mechanistic tools and methodologies for controlling stereoselectivity in radical reactions can be expanded toard ne types of π-bonded unsaturated units (dienes, arenes, diynes, and enynes) and transition metals other than cobalt (Fe, Cr, Mo, , and Mn). © 2015 American Chemical Society.

I propose a technique for reading the base sequence of a single DNA molecule using a graphene nanogap to read the DNA's transverse conductance. Because graphene is a single atom thick, single-base resolution of the conductance is readily obtained. The nonlinear current-voltage characteristic is used to determine the base type Independent of nanogap-width variations that cause the current to change by 5 orders of magnitude. The expected sequencing error rate is 0 % up to a nanogap width of 1.6 nm. © 2010 American Chemical Society.

In this work, we study exact solutions of a generalized nonautonomous cubic-quintic nonlinear Schrödinger equation with higher-order terms, and the dispersion and the nonlinear coefficients engendering temporal dependency. Similarity transformations are used to convert the nonautonomous equation into autonomous one and then we present solutions in a general way. These solutions are obtained for the first class by using the F-expansion method and for the second class constituted by most general bright, dark and front by a direct substitution. We also generalize the external potential which traps the system and the nonlinearities. Finally, the stability of the soliton solutions under slight disturbance of the constraint conditions and initial perturbation of white noise is discussed analytically and numerically. The results reveal that solitons can propagate in a stable way under slight disturbance of the constraint conditions and initial perturbation of a 10% white noise. © 2012 Elsevier B.V.

Scholars and practitioners have reported the positive outcomes of a flipped, or inverted, approach to instruction (Baker, 2000; Lage, Platt, & Treglia, 2000; Bergmann, 2011; Wright, 2011; Pearson, 2012; Butt, 2012; Bates, 2012). While many of the reports are anecdotal, the sheer number of instructors that have reported successful implementation of the strategy provides some evidence of its powerful use as an instructional method. This study provides a detailed case in which one approach of the Flipped Classroom Model of Instruction was applied in two classes at California State University Northridge. Student reports suggest that the approach provided an engaging learning experience, was effective in helping students learn the content, and increased self-efficacy in their ability to learn independently. Additionally, challenges and potential solutions to those challenges are discussed. © 2013 Association for Educational Communications and Technology.

In this study, size-based matrix models for the reef-building coral Orbicella annularis at 14-m depth on the Tektite reef in St. John, U.S. Virgin Islands, were used to: (1) explore the demography of changing coral cover over 25yr, (2) test for spatial homogeneity in demographic properties through a contrast with a previous study (at Yawzi Point, Edmunds and Elahi 2007), and (3) evaluate the potential for future population stability. During three, five year intervals from 1988 to 2002, St. John was affected by hurricanes and bleaching, yet coral cover at Tektite increased from 33% to 49%; from 2002 to 2007, it declined to 27%; and from 2010 to 2013, it stabilized at ~ 28%. Over a quarter-century, colonies>50cm2 became rare, the abundance of colonies≤50cm2 increased from 58% (1988) to 92% (2013), and population density doubled to 67 colonies m-2 by 2013. Population growth (λ) was greater at Tektite (1.152≥λ≥1.018) than Yawzi Point (0.679≥λ≥0.586), and while population size at Tektite declined due to bleaching and disease in 2005 (λ=0.753 over 2003-2008), it recovered between 2008 and 2013 (λ=0.966); the population at Yawzi Point declined from 1988 to 2003 without signs of recovery. Projections suggest a continuation of recent conditions could allow O. annularis at Tektite to retain ~ 9% cover after 100yr, but with a return to the rates of growth and survival of 1993-1998, it could attain coverage similar to that of 1988 (33%) in ~ 15yr. © 2015 Association for the Sciences of Limnology and Oceanography.

I tested the hypothesis that the effects of high pCO 2 and temperature on massive Porites spp. (Scleractinia) are modified by heterotrophic feeding (zooplanktivory). Small colonies of massive Porites spp. from the back reef of Moorea, French Polynesia, were incubated for 1 month under combinations of temperature (29.3°C vs. 25.6uC), pCO 2 (41.6 vs. 81.5 Pa), and feeding regimes (none vs. ad libitum access to live Artemia spp.), with the response assessed using calcification and biomass. Area-normalized calcification was unaffected by pCO 2, temperature, and the interaction between the two, although it increased 40% with feeding. Biomass increased 35% with feeding and tended to be higher at 25.6°C compared to 29.3°C, and as a result, biomass-normalized calcification statistically was unaffected by feeding, but was depressed 12-17% by high pCO 2, with the effect accentuated at 25.6°C. These results show that massive Porites spp. has the capacity to resist the effects on calcification of 1 month exposure to 81.5 Pa pCO 2 through heterotrophy and changes in biomass. Area-normalized calcification is sustained at high pCO 2 by a greater biomass with a reduced biomass-normalized rate of calcification. This mechanism may play a role in determining the extent to which corals can resist the long-term effects of ocean acidification. © 2011, by the Association for the Sciences of Limnology and Oceanography, Inc.
