Multiple GABAA receptor subtypes regulate hippocampal ripple oscillations

High‐frequency oscillations (140–200 Hz) were recorded in behaving rats from the CA1 area of the hippocampus. As generation of these synchronous patterns is assumed to depend on coordinated interneuronal inhibition, we studied the interference of benzodiazepines with the fine structure and occurrence of ripple oscillations. The nonselective GABAA receptor α‐subunit agonist, diazepam, lowered the frequency of ripple oscillations and reduced their occurrence, amplitude and duration. Zolpidem, an α1‐subunit selective benzodiazepine elevated ripple duration but acted similar to diazepam in other respects. The nonselective α‐subunit benzodiazepine antagonist, flumazenil, reduced ripple numbers, amplitude and duration. Wavelet based analysis of the dynamics of intraripple frequency revealed a dramatic decay within a ripple. Only diazepam (1 mg/kg) accelerated this intraripple frequency accommodation. The effects were not due to increased behavioural activity and alertness as evident from vigilance state control. The results suggest a differential role of GABAA receptor subtype specific inhibitory mechanisms in the mediation and fine‐tuning of the network synchronization during ≈200 Hz hippocampal oscillations.
Drivers and Outcomes of Responsiveness to Technological Interruptions from Work during Nonwork TIme

Drawing on identity theory (especially the components of structural symbolic interactionism and role theory—Burke and Stets, 2009; Stryker, 1980) and interruption theory (Thoits, 1991), this dissertation proposes a model that posits identity as an important factor impacting whether or not workers respond to electronic communications from work during nonwork time, and how this relates to career and personal outcomes. Additionally, this research asks what relates to employees’ tetheredness, or their cognitive dependence on communication devices. Results indicate that relational identity, exemplification, and conscientiousness all contribute to tetheredness. Furthermore, the results of this research go against the anecdotal stories of the benefits of being “always on,” finding that greater employee responsiveness to work-nonwork technological interruptions is positively related to increased work-family conflict and job stress. Additionally, the results of this study found that both employees and family members are confronted with blurred boundaries from employee responsiveness to work-nonwork technological interruptions. WFC and job stress serve as mediators between employee responsiveness to work-nonwork technological interruptions and career as well as personal outcomes rated by the focal employee and/or a family member or significant other.
A Relativistic Escape Velocity Maximum of Light Speed

There are parallels between the time distortion equations of General and Special Relativity. The time distortion in Special Relativity limits the “Real” velocity of a particle to the speed of light |c| by slowing the velocity of bosons/energy and increasing the mass of fermion||lepton (or matter) particles. In General Relativity, the gravitational slowdown of bosons/gravitons limits the escape velocity |v Esc| to light speed. |v Esc = (2GM/r)0.5| can also be written as |v Esc2 = 2GM/r|. So an alternate grammar for the equation could be The above contests currently held properties of Schwarzschild Objects. Relativistic theory predicts the slowdown of gravitons/bosons, while their velocity only approaches zero. The different mathe-matical logic of Gravitational Force ||GF|| GF = GMm/r2 would mean no limit on the force. Matter formed through compression of bosons can escape after formation by absorbing kinetic energy from the slowing photons/bosons in its surroundings. So matter formation can occur via a steady-state mechanism. The limit on v Esc allows matter to escape in events that parallel both the Big Bang and Cyclic cosmology. Additional arguments are made as to the validity of relativity.
From In-Place Updates to In-Place Appends: Revisiting Out-of-Place Updates on Flash

Under update intensive workloads (TPC, LinkBench) small updates dominate the write behavior, e.g. 70% of all updates change less than 10 bytes across all TPC OLTP workloads. These are typically performed as in-place updates and result in random writes in page-granularity, causing major write-overhead on Flash storage, a write amplification of several hundred times and lower device longevity. In this paper we propose an approach that transforms those small in-place updates into small update deltas that are appended to the original page. We utilize the commonly ignored fact that modern Flash memories (SLC, MLC, 3D NAND) can handle appends to already programmed physical pages by using various low-level techniques such as ISPP to avoid expensive erases and page migrations. Furthermore, we extend the traditional NSM page-layout with a delta-record area that can absorb those small updates. We propose a scheme to control the write behavior as well as the space allocation and sizing of database pages. The proposed approach has been implemented under Shore- MT and evaluated on real Flash hardware (OpenSSD) and a Flash emulator. Compared to In-Page Logging [21] it performs up to 62% less reads and writes and up to 74% less erases on a range of workloads. The experimental evaluation indicates: (i) significant reduction of erase operations resulting in twice the longevity of Flash devices under update-intensive workloads; (ii) 15%-60% lower read/write I/O latencies; (iii) up to 45% higher transactional throughput; (iv) 2x to 3x reduction in overall write amplification.
Associations between tobacco and cannabis use in remote indigenous populations in Northern Australia.

AIMS To assess whether cannabis use, recently taken up by many indigenous Australians in remote communities, has reinforced tobacco use. DESIGN Cross-sectional study. SETTING Three eastern Arnhem Land communities (Northern Territory, NT); total population = 3384, in 2001. PARTICIPANTS From 1247 people aged 17-36 years, 190 (120 males, 70 females) were opportunistically recruited. MEASUREMENTS Self-reported life-time and current tobacco, cannabis and other substance use were confirmed by local health workers and using clinic records. Participants reported level of substance use, frequency and duration (years used). Associations with tobacco use were calculated (odds ratios: OR) using logistic regression with age, sex, alcohol use and a history of petrol sniffing as confounders. FINDINGS In univariate analyses current tobacco users were more likely than non-users to be using cannabis (OR = 3.1, 1.5-6.2, P = 0.002) and this association remained in multivariate analyses (OR = 3.0, 1.4-6.8, P = 0.006). Tobacco use was associated with the number of years of cannabis use (P = 0.035). The likelihood that tobacco users were also cannabis users increased as quantity of cannabis used increased (P = 0.008). Current tobacco use was no more likely in those who initiated cannabis from 1998 onwards than in those who initiated cannabis before 1998 (OR = 1.1, 0.4-3.2, P = 0.881). One-third of life-time users of both tobacco and cannabis initiated their use at or near the same time, and very few of these (12%) had discontinued either cannabis or tobacco. CONCLUSIONS Cannabis appears to have influenced the continued use of tobacco in these populations with possible additional burdens for cardiovascular and respiratory diseases and challenges for interventions.
Can Life Satisfaction be predicted by Emotional Intelligence, Job Satisfaction and Personality type?

The present study examines the role of Emotional Intelligence, Personality and Job Satisfaction in determination of Life Satisfaction. Data was collected using a battery of tests from two hundred middle and senior level managers who completed the MSCEIT test of EI, NEO Personality scale, Satisfaction with Life Scale and the Index of Job Satisfaction. Results indicated that there was no significant correlation between aspects of Emotional Intelligence and Life Satisfaction scores. A significant positive correlation was seen between Life satisfaction and Job Satisfaction (r= 0.34, p<01), Extraversion (r= 0.31, p<01) as well as Conscientiousness (r=0.22, p<01). Neuroticism was found to have significant negative correlation with Life Satisfaction scores (r= - 0.24, p<01). Multiple regressions analysis results led to emergence of Job Satisfaction (Adj R2 = 0.11) and Extraversion (Adj R2 = 0.17) as positive predictors of Life Satisfaction.
Eye-tracking and corpus-based analyses of syntax-semantics interactions in complement coercion

ABSTRACT Previous work has shown that the difficulty associated with processing complex semantic expressions is reduced when the critical constituents appear in separate clauses as opposed to when they appear together in the same clause. We investigated this effect further, focusing in particular on complement coercion, in which an event-selecting verb (e.g. began) combines with a complement that represents an entity (e.g. began the memo). Experiment 1 compared reading times for coercion versus control expressions when the critical verb and complement appeared together in a subject-extracted relative clause (SRC) (e.g. The secretary that began/wrote the memo) compared to when they appeared together in a simple sentence. Readers spent more time processing coercion expressions than control expressions, replicating the typical coercion cost. In addition, readers spent less time processing the verb and complement in SRCs than in simple sentences; however, the magnitude of the coercion cost did not depend on sentence structure. In contrast, Experiment 2 showed that the coercion cost was reduced when the complement appeared as the head of an object-extracted relative clause (ORC) (e.g. The memo that the secretary began/wrote) compared to when the constituents appeared together in an SRC. Consistent with the eye-tracking results of Experiment 2, a corpus analysis showed that expressions requiring complement coercion are more frequent when the constituents are separated by the clause boundary of an ORC compared to when they are embedded together within an SRC. The results provide important information about the types of structural configurations that contribute to reduced difficulty with complex semantic expressions, as well as how these processing patterns are reflected in naturally occurring language.
Anti-angiogenic Property of Edible Berries

Recent studies show that edible berries may have potent chemopreventive properties. Anti-angiogenic approaches to prevent and treat cancer represent a priority area in investigative tumor biology. Vascular endothelial growth factor (VEGF) plays a crucial role for the vascularization of tumors. The vasculature in adult skin remains normally quiescent. However, skin retains the capacity for brisk initiation of angiogenesis during inflammatory skin diseases such as psoriasis and skin cancers. We sought to test the effects of multiple berry extracts on inducible VEGF expression by human HaCaT keratinocytes. Six berry extracts (wild blueberry, bilberry, cranberry, elderberry, raspberry seed, and strawberry) and a grape seed proanthocyanidin extract (GSPE) were studied. The extracts and uptake of their constituents by HaCaT were studied using a multi-channel HPLC-CoulArray approach. Antioxidant activity of the extracts was determined by ORAC. Cranberry, elderberry and raspberry seed samples were observed to possess comparable ORAC values. The antioxidant capacity of these samples was significantly lower than that of the other samples studied. The ORAC values of strawberry powder and GSPE were higher than cranberry, elderberry or raspberry seed but significantly lower than the other samples studied. Wild bilberry and blueberry extracts possessed the highest ORAC values. Each of the berry samples studied significantly inhibited both H 2 O 2 as well as TNF f induced VEGF expression by the human keratinocytes. This effect was not shared by other antioxidants such as f -tocopherol or GSPE but was commonly shared by pure flavonoids. Matrigel assay using human dermal microvascular endothelial cells showed that edible berries impair angiogenesis.

Applying path analysis method, the study explores the relationships among the influential factors in mathematical modeling academic achievement of 208 high school students. The results showed that all seven factors—academic achievement (MMAA) mathematical modeling self-monitoring ability (MMS-MA), creativity level (CL), the cognitive structure of mathematics and science subjects (CSMSS), mathematical modeling emotion (MME), creative inclination (CI), cognitive style (CS) and mathematical modeling belief (MMB) have significant positive correlation with mathematical modeling.
The Properties of Supernova 1997cy Associated with GRB 970514

The extraordinary SN 1997cy associated with GRB 970514 has been observed photometrically and spectroscopically for nearly 2 yr. At the time of discovery, SN 1997cy was the brightest supernova (SN) ever observed (MV ≤ -20.1, vhel = 19,140 km s-1, H0 = 65 km s-1 Mpc-1). Up to the last available observations (600 days after the gamma-ray burst), the total time-integrated flux was equal to or larger than that expected from the complete thermalization of the γ-rays produced by 2.3 M☉ of 56Co. However, starting already on day 60 the luminosity decline is slower than the 56Co decay rate, indicating that the SN ejecta was interacting with circumstellar material (CSM). The interaction appeared to weaken around day 550. The spectra of SN 1997cy are dominated at all epochs by Hα emission, which shows at least three components of different widths, as in SN 1988Z. Several other lines with different widths are also visible, especially at early epochs. The entire light curve of SN 1997cy is reproduced by a model of the interaction of the very energetic (E = 3 × 1052 ergs) ejecta of a massive star (25 M☉) with the CSM, with some contribution from radioactive decays. The CSM could have been ejected with a mass-loss rate of ≈ 4 × 10-4 M☉ yr-1 as the progenitor star evolved from a blue to a red supergiant about 104 yr before the explosion. The lack of oxygen and magnesium lines in the spectra at nebular phases poses a problem for models requiring high-mass progenitors. The possibility that most of the core material of the progenitor has fallen onto a massive black hole so that the reverse shock dies at the inner edge of the H/He envelope is discussed.
Cot‐nursing using a heated, water‐filled mattress and incubator care: a randomized clinical trial

Aims: To evaluate the thermal responses and weight gain in preterm infants nursed in a cot on a heated, water‐filled mattress (HWM) compared with infants receiving care in an air‐heated incubator and to compare mothers' stress, anxiety levels and perceptions of their infants in the two groups. Methods: Stable preterm infants weighing 1300 to 1500 g were enrolled, being randomly allocated to either the study group (n= 41) receiving care in a cot on an HWM, or the control group (n= 33) receiving incubator care. The mean daily body temperature and episodes of cold stress and hyperthermia were recorded. Weight gain (g kg−1 body weight d−1) was also calculated. The mothers completed questionnaires on their perceptions of their infants, and their anxiety and stress levels before randomization, and 2–3 wk later during the trial. Results: The mean body temperature was similar for the first week of the trial (study group 36.9°C vs controls 36.9°C). There were no significant differences in the incidence of cold stress, while more hyperthermic episodes were seen in the study group (p= 0.03). There were no significant differences in weight gain during the first (study group 21.4 g vs controls 19.6 g) or second weeks of the trial (study group 20.5 g vs controls 19.2 g). Neonatal morbidity did not differ between the groups. There were no differences in mothers' perceptions of their babies, or feelings of stress or anxiety.
MSEE: Stochastic Cognitive Linguistic Behavior Models for Semantic Sensing

Abstract : This report summarizes the major findings from our research on a semantic information representation framework (SIRF) for visual sensing scenarios. First, the concept and architecture of a cognitive linguistic (CL) based SIRF is introduced. Two levels of information abstraction are proposed within this framework. At the syntactic level, a probabilistic contest free grammar (PCFG) method is employed for information compression and summarization. At the semantic level, a Bayesian network approach is used to achieve semantic concept inference and reasoning. To facilitate the functions of this SIRF, several conceptual primitive modeling methods are proposed, which include a dynamic structure preserving map (DSPM) for individual human action recognition, a Gaussian Process Dynamic Model with Social Network Analysis (GPDM-SNA) for a small human group action recognition, an extended GPDM-SNA method for human object interaction (HOI) recognition, and a pyramid histogram of gradient (pHOG) method for human object recognition based on gait images. In addition to these conceptual primitive models, two quantities sensing modality utility assessment methods are introduced. They are essentially feature selection methods, one is based sparse imputation and one is based on 11 graph. Extensive experiments on publicly available datasets have been conducted to assess the effectiveness of the proposed methods, and highly competitive and promising results have been observed.
Personality traits as correlates of suicidal ideation, suicide attempts, and suicide completions: a systematic review

Objective: Involvement of personality traits in susceptibility to suicidality has been the subject of research since the 1950s. Because of the diversity of conceptual and methodological approaches, the extent of their independent contribution has been difficult to establish. Here, we review conceptual background and empirical evidence investigating roles of traits in suicidal behaviors.
Contingency Management for Patients with Cooccurring Disorders: Evaluation of a Case Study and Recommendations for Practitioners

Research indicates that contingency management (CM) has potential to improve a number of outcomes (e.g. substance use, treatment attendance, quality of life) among individuals with substance use and cooccurring disorders. However, multiple factors must be considered on a case-by-case basis in order to promote optimal treatment effects. The present study describes an individualized CM protocol for a US Veteran with substance dependence and cooccurring severe mental illness. CM targeted attendance at outpatient appointments and appropriate use of hospital resources. Effects of CM were assessed by comparing the 3-month baseline and CM periods. The CM intervention marginally reduced unnecessary hospital admissions, resulting in cost savings to the medical center of over $5,000 in three months for this individual. However, CM did not affect outpatient attendance. Several complications arose, highlighting challenges in using CM in populations with substance use and cooccurring disorders. Practical suggestions are offered for maximizing the effects of CM.
Graph Topologies, Gap Metrics, and Robust Stability for Nonlinear Systems

Graph topologies for nonlinear operators which admit coprime factorizations are defined w.r. t. a gain function notion of stability in a general normed signal space setting. Several metrics are also defined and their relationship to the graph topologies are examined. In particular, relationships between nonlinear generalizations of the gap and graph metrics, Georgiou-type formulae, and the graph topologies are established. Closed loop robustness results are given w.r. t. the graph topology, where the role of a coercivity condition on the nominal plant is emphasized.

Studies on the living cornea in vitro. II. The active transport of sodium across the epithelium.

It is generally believed that the normal corneal stroma has a tendency to swell in vivo and that this tendency is countered by some metabolic process in the epithelium, or endothelium, or both. 1-10 One way that this process could act is through the removal of one or more of the constituents of the tissue fluid of the stroma across the cellular surface layers of the cornea. The active transport of water or of any single solute present to the extent of 5 millimoles per liter could be effective in overcoming the swelling force of the stroma. 11 Harris 12,13 has presented some evidence that water itself is actively moved, but others 1,11,14 have suggested that the active transport out of the stroma of an ion such as Na might be a more efficient mechanism. The isolated corneal preparation described in the previous paper has been used to study the
