Query-to-Communication Lifting for BPP

For any $n$-bit boolean function $f$, we show that the randomized communication complexity of the composed function $f\circ g^n$, where $g$ is an index gadget, is characterized by the randomized decision tree complexity of $f$. In particular, this means that many query complexity separations involving randomized models (e.g., classical vs. quantum) automatically imply analogous separations in communication complexity.Comment: 21 page

Life\u27s Form and Formlessness: Translating Yayoi Kusama\u27s Infinity Net

Yayoi Kusama is a world-renowned multidisciplinary artist from Nagano Japan. Her signature mirror rooms have flooded social media websites like Instagram and Twitter. Her strong personal brand and iconic fashion sense has helped solidify her presence as a pop cultural icon throughout the world. She has also played a role in several social movements in America and abroad. Currently, she is arguably the most popular and well-known living female artist in the world. Her captivating work is distinctive due to its trademark forms, hues, silhouettes and patterns. While her work is immediately recognizable, much of its meaning remains enigmatic. For example, in the United States where Japanese is not commonly spoken, language accessibility often limits communicative efficacy especially within fast-faced popular culture. However, there is also the intricate nature of mental illness that makes discussion of Kusama’s artwork even more complex. Regarding evocative artwork, much of an artist’s memories, desires, and fears allow for the manifestation of intimately unique pieces. Kusama’s work encapsulates the often messy, disjointed and oppressed emotions in her life, but she does so in a way that invites others to engage as well. By looking at her work and the cultures that surrounded her life experiences, one can gain a slightly more coherent understanding of the role art plays in both portraying and shaping our beliefs. One can also see how the popular forms of Kusama’s artwork today are the potent culmination of her lived experiences

Progressive retinal degeneration and glial activation in the Cln6nclf mouse model of neuronal ceroid lipofuscinosis : a beneficial effect of DHA and Curcumin supplementation

Neuronal ceroid lipofuscinosis (NCL) is a group of neurodegenerative lysosomal storage disorders characterized by vision loss, mental and motor deficits, and spontaneous seizures. Neuropathological analyses of autopsy material from NCL patients and animal models revealed brain atrophy closely associated with glial activity. Earlier reports also noticed loss of retinal cells and reactive gliosis in some forms of NCL. To study this phenomenon in detail, we analyzed the ocular phenotype of CLN6nclf mice, an established mouse model for variant-late infantile NCL. Retinal morphometry, immunohistochemistry, optokinetic tracking, electroretinography, and mRNA expression were used to characterize retinal morphology and function as well as the responses of Müller cells and microglia. Our histological data showed a severe and progressive degeneration in the CLN6nclf retina co-inciding with reactive Müller glia. Furthermore, a prominent phenotypic transformation of ramified microglia to phagocytic, bloated, and mislocalized microglial cells was identified in CLN6nclf retinas. These events overlapped with a rapid loss of visual perception and retinal function. Based on the strong microglia reactivity we hypothesized that dietary supplementation with immuno-regulatory compounds, curcumin and docosahexaenoic acid (DHA), could ameliorate microgliosis and reduce retinal degeneration. Our analyses showed that treatment of three-week-old CLN6nclf mice with either 5% DHA or 0.6% curcumin for 30 weeks resulted in a reduced number of amoeboid reactive microglia and partially improved retinal function. DHA-treatment also improved the morphology of CLN6nclf retinas with a preserved thickness of the photoreceptor layer in most regions of the retina. Our results suggest that microglial reactivity closely accompanies disease progression in the CLN6nclf retina and both processes can be attenuated with dietary supplemented immuno-modulating compounds

Psychological distress in relation to site specific cancer mortality: pooling of unpublished data from 16 prospective cohort studies

OBJECTIVE:  To examine the role of psychological distress (anxiety and depression) as a potential predictor of site specific cancer mortality. DESIGN:  Pooling of individual participant data from 16 prospective cohort studies initiated 1994-2008. SETTING:  Nationally representative samples drawn from the health survey for England (13 studies) and the Scottish health survey (three studies). PARTICIPANTS:  163 363 men and women aged 16 or older at study induction, who were initially free of a cancer diagnosis, provided self reported psychological distress scores (based on the general health questionnaire, GHQ-12) and consented to health record linkage. MAIN OUTCOME MEASURE:  Vital status records used to ascertain death from 16 site specific malignancies; the three Scottish studies also had information on cancer registration (incidence). RESULTS:  The studies collectively contributed an average of 9.5 years of mortality surveillance during which there were 16 267 deaths (4353 from cancer). After adjustment for age, sex, education, socioeconomic status, body mass index (BMI), and smoking and alcohol intake, and with reverse causality (by left censoring) and missing data (by imputation) taken into account, relative to people in the least distressed group (GHQ-12 score 0-6), death rates in the most distressed group (score 7-12) were consistently raised for cancer of all sites combined (multivariable adjusted hazard ratio 1.32, 95% confidence interval 1.18 to 1.48) and cancers not related to smoking (1.45, 1.23 to 1.71), as well as carcinoma of the colorectum (1.84, 1.21 to 2.78), prostate (2.42, 1.29 to 4.54), pancreas (2.76, 1.47 to 5.19), oesophagus (2.59, 1.34 to 5.00), and for leukaemia (3.86, 1.42 to 10.5). Stepwise associations across the full range of distress scores were observed for colorectal and prostate cancer. CONCLUSION:  This study contributes to the growing evidence that psychological distress might have some predictive capacity for selected cancer presentations, in addition to other somatic diseases

Adapting Urban Water Systems to Manage Scarcity in the 21st Century: The Case of Los Angeles.

Acute water shortages for large metropolitan regions are likely to become more frequent as climate changes impact historic precipitation levels and urban population grows. California and Los Angeles County have just experienced a severe four year drought followed by a year of high precipitation, and likely drought conditions again in Southern California. We show how the embedded preferences for distant sources, and their local manifestations, have created and/or exacerbated fluctuations in local water availability and suboptimal management. As a socio technical system, water management in the Los Angeles metropolitan region has created a kind of scarcity lock-in in years of low rainfall. We come to this through a decade of coupled research examining landscapes and water use, the development of the complex institutional water management infrastructure, hydrology and a systems network model. Such integrated research is a model for other regions to unpack and understand the actual water resources of a metropolitan region, how it is managed and potential ability to become more water self reliant if the institutions collaborate and manage the resource both parsimoniously, but also in an integrated and conjunctive manner. The Los Angeles County metropolitan region, we find, could transition to a nearly water self sufficient system

Selective loss of GABAB receptors in orexin/hypocretin-producing neurons results in disrupted sleep/wakefulness architecture

We generated mice with a selective loss of GABAB receptors in orexin neurons. Orexin neurons in these GABAB1<sup>-/-(orexin)</sup> mice showed reduced responsiveness to GABA<sub>A</sub> receptor agonists due to a compensatory increase in GABAA receptor-mediated inhibition. This increased GABA<sub>A</sub> receptor-mediated inhibition of orexin neurons is due to orexin-1 receptor-mediated activation of local GABAergic interneurons. Surprisingly, orexin neurons were also less responsive to glutamate, apparently because the augmented GABA<sub>A</sub> receptor-mediated inhibition increases the membrane conductance and shunts excitatory currents. These observations indicate that absence of GABA<sub>B</sub> receptors decreases the sensitivity of orexin neurons to both excitatory and inhibitory inputs. GABAB1<sup>-/-(orexin)</sup>mice exhibited severe fragmentation of sleep/wake states during both the light and dark periods without affecting total sleep time or inducing cataplexy, indicating that GABA<sub>B</sub> receptors are crucial regulators of orexin neurons and that "fine tuning" of orexin neurons by inhibitory and excitatory inputs is important for the stability of sleep/waking states
