The Importance of Ergonomics on Urban Squares: Case from Istanbul
There is a close relationship between the creation of urban spaces and ergonomics. To make new stimulating and satisfying urban spaces, ergonomics criteria should consider. In this study, two main urban squares from Istanbul examined. Selected urban squares evaluated by site observation according to the classified ergonomics criteria. Strong and weak points of chosen squares discussed and some suggestions proposed. The results demonstrated the fact that urban equipment meets the individual ergonomic criteria are not sufficient in the use of both squares, and they need to be re-planned.Keywords: Ergomomics; urban squares, IstanbuleISSN: 2398-4287 © 2019.

SppC based energy frontier lepton-proton colliders: luminosity and physics
In this study, main parameters of Super proton-proton Collider (SppC) based
lepton-proton colliders are estimated. For electron beam parameters, highest
energy International Linear Collider (ILC) and Plasma Wake Field
Accelerator-Linear Collider (PWFA-LC) options are taken into account. For muon
beams, 1.5 TeV and 3 TeV center of mass energy Muon Collider parameters are
used. In addition, ultimate p collider which assumes construction of
additional 50 TeV muon ring in the SppC tunnel is considered as well. It is
shown that can be achieved with
moderate upgrade of the SppC proton beam parameters. Physics search potential
of proposed lepton-proton colliders is illustrated by considering small Bjorken
x region as an example of SM physics and resonant production of color octet
leptons as an example of BSM physics.Comment: 11 pages, 3 figures, 8 table
Investigating Urban Ergonomics Features through Healthy City Approach: The Case of Istanbul and Singapore
This study aims to investigate urban ergonomics features through the healthy city approach. Analytic Hierarchy Process (AHP) is adopted to make a pairwise comparison and ranking of multiple features of urban ergonomics. A small online panel was organized with ten experts of architecture and urban design with a minimum of 10 years of experience. Findings from the literature were shared with these experts, and they were asked to compare the ergonomics features pairwise and rank them. For the next step, two main urban squares from Istanbul and two main public spaces of Singapore are examined.

Investigating the Single Production of Vector-Like Quarks Decaying into Top Quark and W Boson through Hadronic Channels at the HL-LHC
We investigate the single production of vector-like quarks at the High
Luminosity LHC (HL-LHC). With the assumed (enhanced) couplings to third
generation quarks of the standard model, vector-like quarks are produced
in association with a bottom () or top () quark, which correspond to
and production modes, including an additional soft forward jet
from the spectator quark (). This study focuses on high-mass vector-like
quarks decaying into a top quark and a boson, resulting in the final
state jets emerging from hadronically decaying top quark () and
boson (). The events with boson and quark have been
analysed using tagging techniques for large-radius jets. The scan ranges of the
mass ( GeV) for the relative width
of vector-like quarks have been investigated. From the results of the
analysis, the masses of vector like quarks B (X) up to 2550 (2450) GeV can be
excluded at CL depending on the type and branching scenarios at
integrated luminosity projection of ab at the HL-LHC.Comment: 18 pages, 5 Tables, 6 Figure
Alcohol consumption leads to loss of healthy life, but the ADH1B*2 allele may still protect from NASH
Nonalcoholic fatty liver disease (NAFLD) is now the most common cause of chronic liver disease worldwide, affecting almost a quarter of the world population (1,2), and is a main cause of severe hepatic complications such as cirrhosis and liver cancer. In histological assessment NAFLD and alcoholic liver disease (ALD) are difficult to distinguish; NAFLD diagnosis thus requires a limit of alcohol intake. However, NAFLD and ALD very frequently coexist in the same patient, making it difficult to identify the exact cause of liver complications. Almost 5?6% of all worldwide deaths (~3 million) are caused by the harmful use of alcohol (https://www.who.int/publications/i/item/9789241565639), therefore alcohol represents a major health problem at a global scale. There is an association between the amount of alcohol consumption and ALD, however, only 30% of chronic drinkers develop alcoholic hepatitis, and 10?20% progress to advanced fibrosis or cirrhosis (3), underscoring the role of genetic factors involved in disease severity and progression. Any level of alcohol consumption, regardless of the amount, leads to loss of healthy life. The recommendation in clinical practice should be to avoid alcohol intake, particularly in the presence of any liver disease. Moderate alcohol consumption has been reported by many studies to be associated with less severe NAFLD, although some of these cross-sectional studies may be affected by selection bias (4-6). In contrast a longitudinal analysis of liver biopsies from patients with NAFLD showed that modest alcohol consumption was associated with lower NASH resolution in comparison with nondrinkers (7). Recently, Chang et al. showed that the risk of liver steatosis in low and moderate alcohol consumers (MACs) was lower in comparison with nondrinkers (8); however, the proportion of hepatic steatosis plus fibrosis was higher in drinkers. The exact mechanism of the deleterious effect of alcohol consumption on NAFLD in obese patients is still unclear. When combined with free fatty acids the polyphenol resveratrol resulted in the stimulation of profibrogenic effects in hepatic stellate cells (key cells for induction and propagation of hepatic fibrosis) instead of any protective role (9). Therefore, it is important to shed light on the exact role of alcohol intake in addition to NAFLD to solve the currently rather conflicting data on this issue. The work published by Vilar-Gomez et al. in Gastroenterology (10) clarifies some knowledge gaps about alcohol metabolism and consumption, and the severity of NAFLD by studying the role of alcohol dehydrogenase (ADH)-1B, in particular ADH1B*2, in this context. The authors started from a finding generated in a previous work by Sookoian et al., where they observed that patients with low alcohol intake and the ADH1B*2 allele showed a less severe NAFLD by histology compared to other patients studied (11). Vilar-Gomez et al. studied 1,697 patients enrolled into various studies conducted by the Nonalcoholic Steatohepatitis Clinical Research Network (NASH CRN) over a period of 10 years [2009?2019]; the NASH CRN Pathology committee reviewed all liver biopsies, and comprehensive alcohol consumption was obtained by AUDIT and LDH questionnaire, binge and heavy drinkers were excluded (170 patients). Remarkably, the frequency of ADH1B*2 carriage varied across race being high in Asians/Pacific Islanders/Hawaiians (86%) and low in non-Hispanic whites (8%), Hispanics (14%), and Blacks (4%), but the study was focused on the 1,153 non-Hispanic whites, which were mainly female, obese, and hypertensive. Among the 1,153 patients, 30% had advanced fibrosis, and 60% had definite NASH. The cohort included 720 non-drinkers and 433 moderate drinkers, but no heavy alcohol consumers. ADH1B*2 carriers were more likely to be male, and moderate alcohol consumption was similar between ADH1B*1 and ADH1B*2 carriersFil: Mazzolini Rizzo, Guillermo Daniel. Universidad Austral.

Galactic Model Parameters and Space Density of Cataclysmic Variables in Gaia Era: New Constraints to Population Models
The spatial distribution, Galactic model parameters and luminosity function
of cataclysmic variables (CVs) are established using re-estimated trigonometric
parallaxes of {\it Gaia} DR3. The data sample of 1,587 CVs in this study is
claimed to be suitable for Galactic model parameter estimation as the distances
are based on trigonometric parallaxes and the {\it Gaia} DR3 photometric
completeness limits were taken into account when the sample was created.
According to the analysis, the scale height of All CVs increases from 2482
to 4304 pc towards shorter periods near the lower limit of the period gap
and suddenly drops to 3002 pc for the shortest orbital period CVs. The
exponential scale heights of All CVs and magnetic systems are found to be
3752 and 2813 pc, respectively, considerably larger than those
suggested in previous observational studies. The local space density of All CVs
and magnetic systems in the sample are 10 and
pc, respectively. Our measurements
strengthen the 1-2 order of magnitude discrepancy between CV space densities
predicted by population synthesis models and observations. It is likely that
this discrepancy is due to objects undetected by CV surveys, such as the
systems with very low and the ones in the period gap. The comparisons
of the luminosity function of white dwarfs with the luminosity function of All
CVs in this study show that 500 times the luminosity function of CVs fits very
well to the luminosity function of white dwarfs. We conclude that the
estimations and data sample in this study can be confidently used in further
analysis of CVs.Comment: 23 pages, including 12 figures and 6 tables, accepted for publication

A phase 2, randomized, double‐blind, placebo‐controlled study of GS‐9450 in subjects with nonalcoholic steatohepatitis
In nonalcoholic steatohepatitis (NASH), the extent of hepatocyte apoptosis correlates with disease severity. Reducing hepatocyte apoptosis with the selective caspase inhibitor GS‐9450 has a potential for altering the course of the liver disease. In this phase 2, double‐blind study, 124 subjects with biopsy‐proven NASH were randomized to once‐daily placebo or 1, 5, 10, or 40 mg GS‐9450 for 4 weeks. Absolute and percent changes from baseline in ALT levels, AST levels, and caspase‐3–cleaved cytokeratin (CK)‐18 fragments at week 4 were assessed by an analysis of covariance model with adjustment for baseline values. In the 40‐mg group, mean (SD) ALT decreased by 47 (43) U/L from baseline to week 4 ( P < 0.0001 versus placebo), and the proportion of subjects with normal ALT increased from 0% to 35% at week 4. In the 40‐mg group, mean AST decreased by 13 U/L from baseline (not significant), and the proportion with normal AST increased from 20% at baseline to 48% at week 4. By week 4, mean CK‐18 fragment levels had decreased to 393 (723) U/L in the GS‐9450 10‐mg group and 125 (212) U/L in the 40‐mg group, but these reductions were not statistically significant. No serious adverse events were reported during treatment, and the percentage of subjects with at least one treatment‐emergent grade 3 or 4 laboratory abnormality ranged from 11.5% to 17% across the GS‐9450 treatment groups versus 35% in the placebo group. Conclusion : GS‐9450 treatment induced significant reductions in ALT levels in NASH patients. Reductions in CK‐18 fragment levels also occurred, although they were not statistically significant. At appropriate therapeutic indices, selective caspase inhibitors may be a promising treatment option in patients with NASH.
