Spaced Retrieval Using Static and Dynamic Images to Improve Face–Name Recognition: Alzheimer's Dementia and Vascular Dementia
Authors: Viccaro Elizabeth , Sands Elaine , Springer Carolyn 
Published: June 2019

Purpose
The primary objective of this study examined whether spaced retrieval (SR) using dynamic images (video clips without audio) is more effective than SR using static images to improve face–name recognition in persons with dementia. A secondary objective examined the length of time associations were retained after participants reached criterion. A final objective sought to determine if there is a relationship between SR training and dementia diagnosis.

Method
A repeated-measures design analyzed whether SR using dynamic images was more effective than SR using static images for face–name recognition. Twelve participants diagnosed with Alzheimer's dementia or vascular dementia were randomly assigned to 2 experimental conditions in which the presentation of images was counterbalanced.

Results
All participants demonstrated improvement in face–name recognition; there was no significant difference between the dynamic and static images. Eleven of 12 participants retained the information from 1 to 4 weeks post training. Additional analysis revealed a significant interaction effect when diagnoses and images were examined together. Participants with vascular dementia demonstrated improved performance using SR with static images, whereas participants with Alzheimer's dementia displayed improved performance using SR with dynamic images.

Conclusions
SR using static and/or dynamic images improved face–name recognition in persons with dementia. Further research is warranted to continue exploration of the relationship between dementia diagnosis and SR performance using static and dynamic images.

Authors: Sánchez J.R. , Bachiller C. , Nova V. , Boria V.E. 
Published: June 2019

This Letter presents a novel continuously tunable microwave resonator based on liquid crystal (LC) material. The reconfigurable device is implemented in Decoupled Empty Substrate Integrated Waveguide (DESIW) technology. DESIW technology allows both magnetic and electric DC (or low frequency) biasing of the LC. The resonator is continuously tunable in a range of 600 MHz, resulting in a measured tunability range of 8.5% around a centre frequency of 7 GHz. Moreover, the measured insertion loss of the reconfigurable device is between 4.3 and 6.8 dB, thus obtaining a Q‐factor of 190‐172.

Published: June 2019

Significance
We uncover the presence of a new topological crystalline insulator (TCI) state in bismuth, which is protected by a twofold rotational symmetry. In contrast to the recently discovered higher-order topological phase in bismuth, the present TCI phase hosts unpinned Dirac cone surface states that could be accessed directly through photoemission experiments. Our study provides a comprehensive understanding of the rich topological electronic structure of bismuth.

Published: June 2019

Significance
Microfibers existing in the tracheary systems of plants are crucial for the plants to survive. These microfilaments are curled up, forming left-handed helices that make the contour of tubes responsible for the transport of water and nutrients from the roots to the leaves. The microfilaments present mechanical properties that vary from plant to plant despite having similar polygonal-helical shapes and cellulose skeletons. Here we show that the surface morphology of the microfilaments, sensed by nematic liquid crystal droplets, is at the origin of entanglements, which are responsible for the mechanical behavior of microfilaments. This work introduces routes for the accurate characterization of plants’ microfilaments and to produce bioinspired textiles.
Classifier use in Heritage and Hong Kong Cantonese
Authors: Nagy Naomi , Lo Samuel 
Published: June 2019

Abstract
Heritage language speakers have frequently been reported to have language skills weaker than homeland
(monolingual) speakers. For example, Wei and Lee (2001, p. 359), a study of
British-born Chinese-English bilingual children’s morphosyntactic patterns (including classifier use), report “evidence of delayed
and stagnated L1 development.” However, many studies compare heritage speaker performance to a prescriptive standard rather than
to spontaneous speech from homeland speakers. We compare spontaneous speech data from two generations of Heritage Cantonese
speakers in Toronto, Canada, and from Homeland Cantonese speakers in Hong Kong. Both groups are similar in a strong preference for
general and mass classifiers, and classifier choice being primarily governed by the noun’s number. We observe specialization of
go3 個 to singular nouns, a grammaticalization process increasing with each generation. The similarity between
homeland and heritage patterns replicates previous studies utilizing the same corpus.
Tone mergers in Cantonese
Authors: Zhang Jingwei 
Published: June 2019

AbstractThis study investigates tone mergers in the Cantonese spoken in Hong Kong, Macao, and Zhuhai. From these three cities, 150 native Cantonese speakers were recruited, stratified by gender and age. Acoustic analyses show that Hong Kong Cantonese and Macao Cantonese are actively merging T2[25] and T5[23], T3[33] and T6[22], thus becoming similar to Zhuhai Cantonese in tonal inventory. The social motivations of the changes are attributed to contact among these Cantonese-speaking communities as well as their contact with Putonghua. Responses to a questionnaire on language use in different domains shows the spread of Putonghua in Hong Kong and Macao and seems to correlate with the advance of the tone mergers. More specifically, the spread of Putonghua in Hong Kong seems to be rolling back the effects of Cantonese standardization, as shown by the tone mergers in the youngest generation in Hong Kong.

ABSTRACT
Mutations frequently occur during breeding of sake yeasts and result in unexpected phenotypes. Here, genome editing tools were applied to develop an ideal nonfoam-forming sake yeast strain, K7GE01, which had homozygous awa1∆/awa1∆ deletion alleles that were responsible for nonfoam formation and few off-target mutations. High-dimensional morphological phenotyping revealed no detectable morphological differences between the genome-edited strain and its parent, while the canonical nonfoam-forming strain, K701, showed obvious morphological changes. Small-scale fermentation tests also showed differences between components of sake produced by K7GE01 and K701. The K7GE01 strain produced sake with significant differences in the concentrations of ethyl acetate, malic acid, lactic acid, and acetic acid, while K701 produced sake with more differences. Our results indicated genuine phenotypes of awa1∆/awa1∆ in sake yeast isolates and showed the usefulness of genome editing tools for sake yeast breeding.
Exploring the write-in process in molecular quantum cellular automata: a combined modeling and first-principle approach

Published: June 2019

Abstract
The molecular quantum cellular automata paradigm (m-QCA) offers a promising alternative framework to current CMOS implementations. A crucial aspect for implementing this technology concerns the construction of a device which effectively controls intramolecular charge-transfer processes. Tentative experimental implementations have been developed in which a voltage drop is created generating the forces that drive a molecule into a logic state. However, important factors such as the electric field profile, its possible time-dependency and the influence of temperature in the overall success of charge-transfer are relevant issues to be considered in the design of a reliable device. In this work, we theoretically study the role played by these processes in the overall intramolecular charge-transfer process. We have used a Landau–Zener (LZ) model, where different time-dependent electric field profiles have been simulated. The results have been further corroborated employing density functional tight-binding method. The role played by the nuclear motions in the electron-transfer process has been investigated beyond the Born-Oppenheimer approximation by computing the effect of the external electric field in the behavior of the potential energy surface. Hence, we demonstrate that the intramolecular charge-transfer process is a direct consequence of the coherent LZ nonadiabatic tunneling and the hybridization of the diabatic vibronic states which effectively reduces the trapping of the itinerant electron at the donor group.
Entropy production for coarse-grained dynamics
Authors: Busiello D M , Hidalgo J , Maritan A 
Published: June 2019

Abstract
Systems out of equilibrium exhibit a net production of entropy. We study the dynamics of a stochastic system represented by a Master equation (ME) that can be modeled by a Fokker–Planck equation in a coarse-grained, mesoscopic description. We show that the corresponding coarse-grained entropy production contains information on microscopic currents that are not captured by the Fokker–Planck equation and thus cannot be deduced from it. We study a discrete-state and a continuous-state system, deriving in both the cases an analytical expression for the coarse-graining corrections to the entropy production. This result elucidates the limits in which there is no loss of information in passing from a ME to a Fokker–Planck equation describing the same system. Our results are amenable of experimental verification, which could help to infer some information about the underlying microscopic processes.

Published: June 2019

Abstract
In mechanical system where spring and damper are used often create unwanted vibration, due to external forces. Unwanted vibration may cause further noise and other damages such as engine break, etc. To reach system stability, we model of coupling series of freight car and analyze them using root loci and plot waves. From the result we can analyze what is the maximum stability by altering spring and damper constant. It is found when the spring and damper constant increase, the stability will be fast.
Two-Stage Algorithm for the Open Vehicle Routing Problem
Authors: Imran A 
Published: June 2019

Abstract
Open Vehicle Routing Problem (OVRP) is a problem that is often found in transportation/distribution problems. On this issue it is known that some consumers are served by several homogeneous vehicles that depart from the depot where after visiting the last consumer the vehicle does not go back to the depot as in the OVRP the vehicle is not possessed by the company. The distribution cost is calculated from the depot until delivery to the last consumer. OVRP will be solved using the 2-stage method. The first stage is the initial construction phase of the solution while the second stage is the quality improvement phase of the solution. The Nearest Neighbor and 2-Opt algorithm are applied to generate the initial solution. The second stage uses Multi-Level Algorithm. The algorithm is equipped with four local searches. The data set from the literature is used to test the algorithm.
Effect of adhesive thickness on the strength of steel-composite joints aged in wet environment
Authors: Sugiman S , Salman S , Setyawan P D , Sulardjaka S 
Published: June 2019

Abstract
This paper presents the effect of adhesive layer thickness on the static strength of adhesively bonded steel-glass fiber-reinforced unsaturated polyester resin (GFRP) lap joints after being aged in water at a temperature of 60°C for 15 days. The adhesive thickness was varied from 0.1 mm to 0.5 mm. It was found that for the dry joints, the static strength increased with the increase of adhesive thickness. However, in wet condition, water really had a significant detrimental effect on the strength of the joints, as most of the strengths of wet joints were much lower than those of the dry joints. In dry condition, mode of failure changed from interfacial (at the adhesive thickness of 0.1 mm) to mix failure; however, for the wet joints; most of failures were at the interface of adhesive/steel.

Authors: Sugiman S , Setyawan P D , Anshari B 
Published: June 2019

Abstract
The paper presents the effect of fiber length on the mechanical properties and water absorption of bamboo fiber/polystyrene-modified unsaturated polyester composites. The fiber length varied from 2.5 mm to 15 mm at the fiber volume fraction of 0.2, 0.25 and 0.3. For water absorption, the specimens were immersed in distilled water at temperature of 40°C. The results showed that for all volume fractions, the tensile, flexural, and the impact properties tended to increase with the increase of fiber length; however, there was an optimum fiber length for the tensile and flexural properties. The water uptake increased with the increase of both fiber length and volume fraction. In wet condition, for all volume fractions, the flexural properties degraded, whereas, the impact strength did not indicate degradation, even; it significantly increased for all fiber lengths.

Published: June 2019

Abstract
Biomass from empty fruit bunch (EFB) is considered as potential renewable energy sources to be developed in Indonesia. EFB can be efficiently converted into valuable and useful fuel products through gasification. Gasification is a process of biomass conversion into syngas. Syngas is a raw material for most other chemical products, such as Methanol, Ammonia, and DME. One of the biomasses that has big potential to be utilized is palm EFB waste. Research about DME synthesis from various biomass has been done, though little research about DME production based on EFB gasification. The aim of this research is to simulate single stage DME Plant Model based on gasification of EFB by assuming that the gasification reaction and DME synthesis reaction are under equilibrium condition. Method encompasses step to perform simulation of the model and DME plant design. The model predicts yield of DME product in agreement with published real DME plant operation. The result shows flow rate of DME produced is 50% of EFB feed flowrate and 73% energy efficiency obtained for pre-treated EFB. Electric power requirement has been investigated at 4096 kW and can be fulfilled by DME Plant through steam generation cycle and internal combustion engine fuelled by DME product. The model developed will be used as a basis for techno-economic analysis of DME plant based on EFB gasification.

An experimental study on thermal catalytic decomposition of inulin to 5 hydroxymethylfurfural and levulinic acid and the effect of C6 on furfural during the decomposition process
Authors: Fachri B A 
Published: June 2019

Abstract
The attractive biobased platform chemicals, 5-Hydroxymethylfurfural (HMF) and Levulinic Acid (LA), are commonly produced by the conversion of monomeric sugars. Nevertheless, a polymeric sugar such as inulin shows promising. This work reports the study on the thermal catalytic decomposition of inulin to HMF and LA. This work also investigated the effect of furfural during the process. The decomposition reactions were conducted in a batch reactor in a temperature (153-187)°C, an inulin loading (0.03- 0.12) g mL−1 and reaction times (18 -74 minutes) using a central composite experimental design. Furthermore, to study the effect of fructose and glucose on furfural, some additional experiments were also performed in the batch system. The decomposition process gained 35 wt% yield of HMF and 13 wt % yield of LA. The HMF and the LA model were statistically formulated and showed a good fit to the experimental data. The fructose particularly plays a role in furfural disappearance during the process.

Published: June 2019

AbstractOne of the ester product of glycerol and acetic acid is triacetin which has wide industrial aplication. In this study the esterification of glycerol with acetic acid over Lewatite catalyst to produce triacetin, were carried out. Lewatite is one of ion exchange resin, the use of ion exchange resins as catalyst will not produce waste, not corrosive, high thermal stability and has good selectivity. The esterification reaction of glycerol with acetic acid were performed in a three-neck flask with stirrer (175 rpm) at temperature (90 °C, 100 °C and 110 °C) and atmosphere pressure. A 9.66 % selectivity of triacetin with conversion (77.4 %) was achieved at 100 °C within 90 minutes of reaction time. This research aimed to report experimental data and kinetic modeling of glycerol esterification with acetic acid to evaluate and compare model performance and capability. A kinetic model was developed using a first order pseudo-homogeneous model according to the experimental data. The surface reaction of acetic acid with glycerol was assumed to be rate-controlling. The effect of temperature to rate of reaction constants can be expressed as follows:kr=8.138 x 1011 exp(−57,176.47RT)(1s)
A Kinetics study of 2-ethyl-2-hexenal hydrogenation to 2-ethyl-hexanol over Nickel based catalyst
Authors: Virgana S , Subagjo  , Gunawan M L 
Published: June 2019

Abstract
The 2-ethyl-hexanol was much-needed in the plasticizer industry as a precursor for the synthesis of bis diesters (2-ethyl hexyl) phthalate (DEHP). This compound can be synthesized by oxo reaction, where one of the steps isa consecutive hydrogenation of the 2-ethyl-2-hexenal to 2-ethyl-hexanol. This reaction required metal-based catalyst. This research aimed to develop the formula and procedure of catalyst synthesized and get a kinetics of the reaction. The catalyst was synthesized with a nickel content of 50%-w. The support consists of γ-alumina and SiO2(cab-osil) in variations of 0%-w up to 100 %-w of cab-o-sil towards support. The activity of synthesized catalysts were tested at 120°C and 30 bars in the fixed bed reactor. The results showed that the best performing catalyst was NiO50-Cab50 with 98.29% 2-ethyl-2-hexenal conversion and selectivity to 2-ethyl-hexanol 87.41 %. By varying the reaction temperature of 100-120°C in the best catalyst, it is found that the consecutive reaction was the first order with the activation energy of 2-ethyl-2-hexenal hydrogenation to 2-ethyl-hexanal was 33.66 kJ/mol and hydrogenation 2-ethyl-hexanal to 2-ethyl-hexanol was 58.39 kJ/mol. This showed that the hydrogenation of C = C bonds was easier than the C = O bond.
