Superconducting H5S2 phase in sulfur hydrogen system under high pressure
Venue: Scientific reports

Recently, hydrogen sulfide was experimentally found to show the high superconducting critical temperature (Tc) under high pressure. The superconducting Tc shows 30 70 K in pressure range of 100 170 GPa (low Tc phase) and increases to 203 K, which sets a record for the highest Tc in all materials, for the samples annealed by heating it to room temperature at pressures above 150 GPa (high Tc phase) Here we present a solid H5S2 phase predicted as the low Tc phase by the application of the genetic algorithm technique for crystal structure searching and first principles calculations to sulfur hydrogen system under high pressure. The H5S2 phase is thermodynamically stabilized at 110 GPa, in which asymmetric hydrogen bonds are formed between H2S and H3S molecules. Calculated Tc values show 50 70 K in pressure range of 100 150 GPa within the harmonic approximation, which can reproduce the experimentally observed low Tc phase. These findings give a new aspect of the excellent superconductivity in compressed sulfur hydrogen system.
High pressure induced distortion in face centered cubic phase of thallium
Venue: Proceedings of the National Academy of Sciences

The III A metals (i.e. Al, Ga, and In) have displayed complexity of structural phase transitions under high pressure. The contribution of d electrons to valence states has been investigated previously and has been suggested to be responsible for that behavior. Here, another III A metal, Tl, is predicted to be an unusual distorted f.c.c. structure (b.c.t. at high pressure and then is confirmed by using the angle dispersive X ray diffraction method. The enhancement of sp d mixing states at valence bands with the increasing pressure is suspected to be the cause of distortion in Tl. The transformation pathway of Tl is intended to be h.c.p f.c.c b.c.t. under compression. Tl is an important element in high temperature superconducting compounds; thus the present study has great implications in the area of superconductivity. The complex and unusual high pressure phase transition of III A (i.e. Al, Ga, and In) metals have been investigated in the last several decades because of their interesting periodic table position between the elements having metallic and covalent bonding. Our present first principles based electronic structure calculations and experimental investigation have revealed the unusual distortion in face centered cubic (f.c.c. phase of the heavy element thallium (Tl) induced by the high pressure. We have predicted body centered tetragonal (b.c.t) phase at 83 GPa using an evolutionary algorithm coupled with ab initio calculations, and this prediction has been confirmed with a slightly distorted parameter (2 x a c)/c lowered by 1% using an angle dispersive X ray diffraction technique. The density functional theory (DFT) based calculations suggest that s p mixing states and the valence core overlapping of 6s and 5d states play the most important roles for the phase transitions along the pathway h.c.p f.c.c. b.c.t.
AppGrouper: Knowledge graph based Interactive Clustering Tool for Mobile App Search Results

A relatively new feature in Google Play Store presents mobile app search results grouped by topic, helping users to quickly navigate and explore. The underlying Search Results Clustering (SRC) system faces several challenges, including grouping search results in topical coherent clusters as well as finding the appropriate level of granularity for clustering. We present AppGrouper, an alternative approach to algorithmic only solutions, incorporating human input in a knowledge graph based clustering process. AppGrouper provides an interactive interface that lets domain experts steer the clustering process in early, mid, and late stages. We deployed and evaluated AppGrouper with internal experts. We found that AppGroup improved quality of algorithm generated app clusters on 56 out of 82 search queries. We also found that the internal experts made more changes in early and mid stages for lower quality algorithmic results, focusing more on narrow queries. Our result suggests, in some contexts, machine learning systems can greatly benefit from steering from human experts, creating a symbiotic working relationship.

On thermal stability and catalytic reactivity of Zr based metal organic framework (UiO 67) encapsulated Pt catalysts

Pt nanoparticles (NPs, 0.5 wt. encapsulated in a zirconium based metal organic framework (UiO 67 MOF) were synthesized via a linker design method. Thermal behavior of Pt in UiO 67 composite materials was compared with UiO 67 using thermogravimetric and differential thermal analysis (TG DTA) The results showed that Pt insertion can impair the thermal stability of bulk UiO 67, resulting in a ca. 14% drop in the critical temperature of the thermal decomposition. Temperature programmed oxidation of materials showed that calcination at 450 K was essential to provide a clean framework. Temperature programmed reduction of materials revealed that the chemisorption of H 2 on UiO 67 (at 323 K) was evidently enhanced owing to the incorporation of Pt NPs, thus making PtNP@UiO 67 suitable for hydrogenation reactions and hydrogen storage. PtNP@UiO 67 catalyst was evaluated by the oxidation and hydrogenation of 5 hydroxymethylfurfural in aqueous solutions at 363 K, showing improved activity and selectivity in hydrogenation reactions.
Performance and Egg Quality of Laying Hens Fed Diets Supplemented with Herbal Extracts and Flaxseed

In this experiment, the effects of fennel and thyme extracts with and without flaxseed were investigated on performance and egg quality of Leghorn type laying hens (Hy Line W 36) 200 laying hens from 26 to 38 weeks of age were assigned to five dietary treatments with five replications. The treatment groups were: 1) Control (a diet without any additives) 2) control diet plus fennel (40 mg/kg feed) 3) control diet plus thyme (40 mg/kg feed) 4) a diet containing flaxseed and fennel; and 5) a diet containing flaxseed plus thyme. There were significant differences in feed intake and egg weight between the treatments (p 0.05) The egg yolk color index in hens that received thyme extract and flaxseed treatment was significantly higher than other treatments (p 0.05) Hens fed control diet had lower Haugh unit compared to other treatments that contained herbal extracts. The eggshell strength was significantly higher in hens that received thyme extract and flaxseed treatments than control (p 0.05) The eggshell weight in treatments containing flaxseed was significantly higher compared to the other treatments (P 0.05) The lowest egg yolk cholesterol concentration was found in hens fed thyme and flaxseed treatment. The hens fed plant extracts and flaxseed diets had eggs with low palmitic and stearic acids and high a linolenic acid. It is concluded that thyme and fennel extracts, as well as flaxseed, improved the performance and egg quality of laying hens. The use of flaxseed and thyme extract improved egg yolk omega 3 fatty acids and decreased yolk cholesterol content.

Lexical Verbs in Malaysian University English Test Argumentative Essays: A Corpus based Structural Analysis

Argumentative writing is regarded as an essential form of written discourse in Malaysia, specifically in Malaysian University English Test (MUET) Accordingly, there are numerous studies on argumentative essays which demonstrate the increased interest in linguistic features. Conversely, limited studies have been conducted on the written discourse of the MUET argumentative essay at pre university level. For this purpose, using a compiled representative learner corpus, a preliminary study is conducted to investigate the linguistic features; lexical verbs used in Band 5 and Band 3 argumentative essays produced by students of a pre university college in Malaysia. Subsequently, the lexical verbs utilized in the respective essays were compared. As a descriptive analysis and corpus based study, the use of lexical verb forms was examined via a computer assisted corpus analysis, for short (CACA) reflecting the learners' knowledge of applying this linguistic constituent into their written essays. Albeit, this analysis revealed that both Band 5 and Band 3 essays employed four types of lexical verbs, namely past tense (VVD) 'ing' form (VVG) past participle (VVN) and s form (VVZ) it was apparent that the lexical verb form of past tense (VVD) was underused by both groups (11 and 20 occurrences respectively) Surprisingly, both groups had avoided the base form of lexical verb (VVO) in their essays. Thus, the findings of this study might render some pedagogical implications for both teachers and learners, especially in writing argumentative essays, and ideas for future research.

Predictors of Recurrent AKI.
Venue: Journal of the American Society of Nephrology JASN

Recurrent AKI is common among patients after hospitalized AKI and is associated with progressive CKD. In this study, we identified clinical risk factors for recurrent AKI present during index AKI hospitalizations that occurred between 2003 and 2010 using a regional Veterans Administration database in the United States. AKI was defined as a 0.3 mg/dl or 50% increase from a baseline creatinine measure. The primary outcome was hospitalization with recurrent AKI within 12 months of discharge from the index hospitalization. Time to recurrent AKI was examined using Cox regression analysis, and sensitivity analyses were performed using a competing risk approach. Among 11,683 qualifying AKI hospitalizations, 2954 patients (25% were hospitalized with recurrent AKI within 12 months of discharge. Median time to recurrent AKI within 12 months was 64 (interquartile range 19 167) days. In addition to known demographic and comorbid risk factors for AKI, patients with longer AKI duration and those whose discharge diagnosis at index AKI hospitalization included congestive heart failure (primary diagnosis) decompensated advanced liver disease, cancer with or without chemotherapy, acute coronary syndrome, or volume depletion, were at highest risk for being hospitalized with recurrent AKI. Risk factors identified were similar when a competing risk model for death was applied. In conclusion, several inpatient conditions associated with AKI may increase the risk for recurrent AKI. These findings should facilitate risk stratification, guide appropriate patient referral after AKI, and help generate potential risk reduction strategies. Efforts to identify modifiable factors to prevent recurrent AKI in these patients are warranted.
Prevention of cardiac surgery associated AKI by implementing the KDIGO guidelines in high risk patients identified by biomarkers: the PrevAKI randomized controlled trial
Venue: Intensive Care Medicine

PurposeCare bundles are recommended in patients at high risk for acute kidney injury (AKI) although they have not been proven to improve outcomes. We sought to establish the efficacy of an implementation of the Kidney Disease Improving Global Outcomes (KDIGO) guidelines to prevent cardiac surgery associated AKI in high risk patients defined by renal biomarkers.MethodsIn this single center trial, we examined the effect of a "KDIGO bundle" consisting of optimization of volume status and hemodynamics, avoidance of nephrotoxic drugs, and preventing hyperglycemia in high risk patients defined as urinary [TIMP 2][IGFBP7] 0.3 undergoing cardiac surgery. The primary endpoint was the rate of AKI defined by KDIGO criteria within the first 72 h after surgery. Secondary endpoints included AKI severity, need for dialysis, length of stay, and major adverse kidney events (MAKE) at days 30, 60, and 90.ResultsAKI was significantly reduced with the intervention compared to controls [55.1 vs. 71.7% ARR 16.6% (95 CI 5.5 27.9% p 0.004] The implementation of the bundle resulted in significantly improved hemodynamic parameters at different time points (p 0.05) less hyperglycemia (p 0.001) and use of ACEi/ARBs (p 0.001) compared to controls. Rates of moderate to severe AKI were also significantly reduced by the intervention compared to controls. There were no significant effects on other secondary outcomes.ConclusionAn implementation of the KDIGO guidelines compared with standard care reduced the frequency and severity of AKI after cardiac surgery in high risk patients. Adequately powered multicenter trials are warranted to examine mortality and long term renal outcomes.
Incidence, risk factors and outcomes of acute kidney injury (AKI) in patients with acute on chronic liver failure (ACLF) of underlying cirrhosis
Venue: Hepatology International

kidney injury (AKI) is a life threatening complication in patients with acute on chronic liver failure (ACLF) of underlying cirrhosis. However, the characteristics of AKI in these patients have not been clarified. Our aim was to determine the incidence and risk factors of AKI and the association between AKI severity and 180 day transplant free survival.MethodsWe performed a retrospective cohort analysis of patients with ACLF of underlying cirrhosis in a single center from January 2009 through December 2014. AKI was defined by the criteria proposed by International Club of Ascites (ICA) The incidence and risk factors of AKI development and its relationship to 180 day transplant free survival rates were evaluated.ResultsOf 1032 patients with ACLF of underlying cirrhosis, 121 (11.72 had AKI at admission, and 319 (30.9 developed AKI during hospitalization. We established a logistic regression model including four independent factors with AKI development: MELD score [odds ratio (OR) 1.1; 95 confidence interval (CI) 1.07 1.14] presence of ascites (OR, 3.80; 95 CI, 2.13 6.78) sepsis/infection (OR, 2.25; 95 CI, 1.66 3.03) and acute variceal bleed (OR, 1.78; 95 CI, 1.00 3.19) The area under receiver operating characteristics of the model in internal and external validations were 0.95 and 0.85, respectively. Patients with mild A AKI had a higher 180 day transplant free survival rate (23.8 than patients with mild B AKI (19.0 or marked AKI (5.9 (all p 0.001) AKI patients with a peak value of sCr <1.5 mg/dl had higher 180 day transplant free survival rates compared to those with a peak value of sCr =1.5 mg/dl (23.8 vs. 14.7 p 0.001).ConclusionsWe developed a clinical risk model for predicting development of AKI with great accuracy. Combining the ICA AKI criteria and the peak value of sCr with 1.5 mg/dl provides a good prognostic method for patients with ACLF of underlying cirrhosis.

Experimental Analysis of a Gas Micro Cogeneration Based on Internal Combustion Engine and Calibration of a Dynamic Model for Building Energy Simulation

Internal combustion engine (ICE) based micro cogeneration (uCHP) covers a wide range of capacities and recent developments increased the efficiency through condensing exhaust device and variable speed pumps. This type of equipment is suitable for residential and commercial buildings and is usually integrated in a system with back up boiler. A dynamic model is required to investigate the seasonal energy performance of these equipments. A generic grey box model with few and easily accessible parameters has been developed to simulate the dynamics of the heat and electricity productions of an ICE based uCHP. The unit under scope develops an electrical power of 7.5 kW and a thermal power of 20 kW. The test facility is described and the uncertainty of the measurement chain is assessed. The static and dynamic parameters of the micro cogeneration model have been identified based on a set of experimental data representative of all operating conditions. The model will be used to undertake building energy simulation studies in various cases such as collective housing, commercial buildings, hotels to identify the optimal sizing of components (uCHP, back up, storage) and controls for various tariffs (self consumption, feed in, sale back)
