Concurrent Validity and Reliability of the Core Lexicon Measure as a Measure of Word Retrieval Ability in Aphasia Narratives
Authors: Kim Hana , Wright Heather Harris
Published: November 2019

Purpose

General agreement exists in the literature that clinicians struggle with quantifying discourse-level performance in clinical settings. Core lexicon analysis has gained recent attention as an alternative tool that may address difficulties that clinicians face. Although previous studies have demonstrated that core lexicon measures are an efficient means of assessing discourse in persons with aphasia (PWAs), the psychometric properties of core lexicon measures have yet to be investigated. The purpose of this study was (a) to examine the concurrent validity by using microlinguistic and macrolinguistic measures and (b) to demonstrate interrater reliability without transcription by raters with minimal training.

Method

Eleven language samples collected from PWAs were used in this study. Concurrent validity was assessed by correlating performance on the core lexicon measure with microlinguistic and macrolinguistic measures. For interrater reliability, 4 raters used the core lexicon checklists to score audio-recorded discourse samples from 10 PWAs.

Results

The core lexicon measures significantly correlated with microlinguistic and macrolinguistic measures. Acceptable interrater reliability was obtained among the 4 raters.

Conclusions

Core lexicon analysis is potentially useful for measuring word retrieval impairments at the discourse level. It may also be a feasible solution because it reduces the amount of preparatory work for discourse assessment.

Authors: Kummer Benjamin R. , Willey Joshua Z. , Zelenetz Michael J. , Hu Yiping , Sengupta Soumitra , Elkind Mitchell S. V. , Hripcsak George
Published: November 2019

Background Neurologists perform a significant amount of consultative work. Aggregative electronic health record (EHR) dashboards may help to reduce consultation turnaround time (TAT) which may reflect time spent interfacing with the EHR.

Objectives This study was aimed to measure the difference in TAT before and after the implementation of a neurological dashboard.

Methods We retrospectively studied a neurological dashboard in a read-only, web-based, clinical data review platform at an academic medical center that was separate from our institutional EHR. Using our EHR, we identified all distinct initial neurological consultations at our institution that were completed in the 5 months before, 5 months after, and 12 months after the dashboard go-live in December 2017. Using log data, we determined total dashboard users, unique page hits, patient-chart accesses, and user departments at 5 months after go-live. We calculated TAT as the difference in time between the placement of the consultation order and completion of the consultation note in the EHR.

Results By April 30th in 2018, we identified 269 unique users, 684 dashboard page hits (median hits/user 1.0, interquartile range [IQR] = 1.0), and 510 unique patient-chart accesses. In 5 months before the go-live, 1,434 neurology consultations were completed with a median TAT of 2.0 hours (IQR = 2.5) which was significantly longer than during 5 months after the go-live, with 1,672 neurology consultations completed with a median TAT of 1.8 hours (IQR = 2.2; p = 0.001). Over the following 7 months, 2,160 consultations were completed and median TAT remained unchanged at 1.8 hours (IQR = 2.5).

Conclusion At a large academic institution, we found a significant decrease in inpatient consult TAT 5 and 12 months after the implementation of a neurological dashboard. Further study is necessary to investigate the cognitive and operational effects of aggregative dashboards in neurology and to optimize their use.
Endoscopic-Assisted Lateral Corridor to the Infratemporal Fossa: Proposal and Quantitative Comparison to the Endoscopic Transpterygoid Approach
Authors: Yacoub Abraam , Schneider Daniel , Ali Ahmed , Wimmer Wilhelm , Caversaccio Marco , Anschuetz Lukas
Published: November 2019

Objective This study was aimed to propose an expanded endoscopic-assisted lateral approach to the infratemporal fossa (ITF) and compare its area of exposure and surgical freedom with the endoscopic endonasal transptergyoid approach (EETA).

Methods Anatomical dissections were performed in five cadaver heads (10 sides). The ITF was first examined through the endoscopically assisted lateral corridor, herein referred to as the endoscopic-assisted transtemporal fossa approach (TTFA). After that, the EETA was performed and coupled with two sequential maxillary procedures (medial maxillectomy [MM], and endoscopic-assisted Denker's approach [DA]). Using the stereotactic neuronavigation, measurements of the area of exposure and surgical freedom at the foramen ovale were determined for the previously mentioned approaches.

Results Bimanual exploration of the ITF through the endoscopic-assisted lateral approach was achieved in all specimens. The DA (729 ± 49 mm2) provided a larger area of exposure than MM (568 ± 46 mm2; p < 0.0001). However, areas of exposure were similar between the DA and the TTFA (677 ± 35 mm2; p = 0.09). The surgical freedom offered by the TTFA (109.3 ± 19 cm2) was much greater than the DA (24.7 ± 4.8 cm2; p < 0.0001), and the MM (15.2 ± 3.2 cm2, p < 0.0001).

Conclusion The study demonstrates the feasibility of the proposed approach to provide direct access to the extreme extensions of the ITF. The lateral corridor offers an ideal working area in the posterior compartment of the ITF without crossing over important neurovascular structures. The new technique may be used alone in selected primary ITF lesions or in combination with endonasal approaches in pathologies spreading laterally from the nose or nasopharynx.
Suppressing epidemic spreading by optimizing the allocation of resources between prevention and treatment
Authors: Li Jiayang , Yang Chun , Ma Xiaotian , Gao Yachun , Fu Chuanji , Yang Hongchun
Published: November 2019

The rational allocation of resources is crucial to suppress the outbreak of epidemics. Here, we propose an epidemic spreading model in which resources are used simultaneously to prevent and treat disease. Based on the model, we study the impacts of different resource allocation strategies on epidemic spreading. First, we analytically obtain the epidemic threshold of disease using the recurrent dynamical message passing method. Then, we simulate the spreading of epidemics on the Erdős-Rényi (ER) network and the scale-free network and investigate the infection density of disease as a function of the disease infection rate. We find hysteresis loops in the phase transition of the infection density on both types of networks. Intriguingly, when different resource allocation schemes are adopted, the phase transition on the ER network is always a first-order phase transition, while the phase transition on the scale-free network transforms from a hybrid phase transition to a first-order phase transition. Particularly, through extensive numerical simulations, we find that there is an optimal resource allocation scheme, which can best suppress epidemic spreading. In addition, we find that the degree heterogeneity of the network promotes the spreading of disease. Finally, by comparing theoretical and numerical results on a real-world network, we find that our method can accurately predict the spreading of disease on the real-world network.
DC measurement of dressed states in a coupled 100 GHz resonator system using a single quasiparticle transistor as a sensitive microwave detector
Authors: Lotkhov S. V. , Dolata R. , Khabipov M.
Published: November 2019

We report on the on-chip detection of microwaves in the frequency range around 100 GHz. For the purpose of detection, we employ a discrete transport channel triggered in a superconducting single-electron transistor by photon-assisted tunneling of quasiparticles. The technique is applied to observe the spectrum of the dressed states of a model circuit quantum electrodynamics system consisting of a superconducting coplanar resonator coupled to a Josephson oscillator. The dressed states appear as typical resonance anticrossing exhibiting, in our case, an expectedly wide frequency splitting corresponding to the Jaynes–Cummings coupling strength, g/π∼ 10 GHz. Due to the high decay rate, γ∼ 20–40 GHz, in the very transparent Josephson junctions used, the strong coupling limit, g≫γ, which is required for qubit operation, is not achieved, and the photon population in the resonator is low, ⟨n⟩< 1. Remarkably, the continuous readout of the low population states demonstrates the high microwave sensitivity of the detector.
Quantifying non-Markovianity in underdamped versus overdamped environments and its effect on spectral lineshape
Authors: Green Dale , Humphries Ben S. , Dijkstra Arend G. , Jones Garth A.
Published: November 2019

Non-Markovian effects in open quantum systems are central to understanding spectral lineshape. Here, we quantify the non-Markovianity associated with both overdamped and underdamped vibrations in terms of information flow between the bath and the system and compare this with the broadening and ellipticity of two-dimensional spectra. Using the Breuer Laine Piilo (BLP) measure, we link the well-known stochastic models for spectral lineshape with modern quantum information theory. Specifically, we study the effect of non-Markovianity in a system in contact with underdamped vibrations and examine the differences observed on increasing the damping to the overdamped limit. The open quantum system dynamics are evolved using the hierarchical equations of motion, efficiently terminated with a Markovian cutoff, where separate hierarchies are derived for the underdamped and overdamped environments. It is shown that the BLP measure is quantitatively correlated with the ellipticity of two-dimensional spectra and memory effects are more pronounced in underdamped environments, due to the long-lived feedback of information between the system and its bath, compared to overdamped environments. Environmental signatures in spectral lineshapes emerge as a result of information flow from the bath back into the system.
Thermoelectric properties improvement in quasi-one-dimensional organic crystals
Authors: Sanduleac Ionel , Pflaum Jens , Casian Anatolie
Published: November 2019

The charge and energy transport in highly conducting quasi-one-dimensional organic crystals of p-type tetrathiotetracene-iodide, TTT2I3, and of n-type tetrathiotetracene-tetracyanoquinodimethane, TTT(TCNQ)2, is studied. Two electron-phonon interactions are considered simultaneously. One interaction is of the acoustic deformation potential type and the other one is of polaronic character. Charge transport along the conducting molecular chains is bandlike, whereas in the transversal directions, it is of the hopping type. It is shown that due to a partial compensation of these interactions for a narrow interval of states in the one-dimensional conduction band, the relaxation time is of Lorentzian shape and shows a distinct dependence on carrier energy with a pronounced maximum. The scattering of charge carriers on adjacent molecular chains and by impurities and structural defects limits the height of this maximum. However, rather high relaxation times might be anticipated in the case of perfect single crystals. As the carriers in these states show an enhanced mobility, this will lead to a simultaneous increase of electrical conductivity and Seebeck coefficient. It is proposed that, if the above-mentioned crystals could be accomplished by means of sufficient purification and by optimization of the carrier concentration, so that the Fermi level is close to energetic states for which the relaxation time has a maximum, one might achieve values for the thermoelectric figure of merit ZT∼5 in crystals of tetrathiotetracene-iodide and ZT∼1.5 in those of tetrathiotetracene-tetracyanoquinodimethane.
Intensification of shock damage through heterogeneous phase transition and dislocation loop formation due to presence of pre-existing line defects in single crystal Cu
Authors: Reddy K. Vijay , Deng Chuang , Pal Snehanshu
Published: November 2019

In general, shock wave deformation studies of perfect single crystals may cause disagreement with the experimental findings as the complete elimination of all defects in the metallic system is not possible in reality. Here, we have studied the influence of edge and screw dislocations on the intensification of damage produced during the propagation of shock at various velocities. Various analyses have been performed such as common neighbor analysis, atomic strain analysis, stress analysis, and kinetic energy mapping to investigate the underlying plastic deformation mechanisms. Results have revealed that the presence of edge dislocations has caused intensified damage through localized amorphization and phase transition. In comparison with the perfect crystal, the presence of pre-existing edge dislocations has incurred an additional damage of ∼17% to the specimen region. On the other hand, the presence of screw dislocations in the specimen causes damage through shear bands and dislocation loop formation, which is found to constitute greater than 80% of the specimen region.
Single-layer CdPSe3: A promising thermoelectric material persisting in high temperatures
Authors: Yun Won Seok , Lee J. D.
Published: November 2019

Searching for two-dimensional (2D) functional semiconductors with excellent performance is a central issue in the field of 2D materials. Using the first-principles calculation combined with the Boltzmann transport theory, we survey the thermodynamic stabilities, electronic transports, and thermoelectric performances of single-layer (1L-) CdPSe3, which is a transition-metal phosphorus trichalcogenide. Through an investigation of the cleavage energy, we reveal that an isolation into 1L-CdPSe3 from the bulk form is guaranteed, which is in addition thermodynamically stable, as confirmed by both the first-principles molecular dynamics and the phonon spectrum. Electron and hole mobilities of 1L-CdPSe3 are calculated and found to be ∼390 and ∼300 cm2 V−1 s−1, respectively. The lattice thermal conductivity of 1L-CdPSe3 is shown to be as low as ∼1.25 W m−1 K−1 at room temperature. Finally, the thermoelectric figure of merit of 1L-CdPSe3 is calculated to be ∼1.2 under the p-type optimal doping at a high temperature (1200 K). This suggests that 1L-CdPSe3 could be a promising candidate for pursuing an excellent thermoelectric functionality, in particular, valid even at high temperatures.
A double-beam piezo-magneto-elastic wind energy harvester for improving the galloping-based energy harvesting
Authors: Yang Kai , Wang Junlei , Yurchenko Daniil
Published: November 2019

This study investigates the performance of a double-beam piezo-magneto-elastic wind energy harvester (DBPME-WEH) when exhibiting a galloping-based energy harvesting regime under wind excitation. The DBPME-WEH comprises two piezoelectric beams, each of which supports a prism bluff body embedded with a magnet at the tip. The magnets are oriented to repulse each other to introduce a bistable nonlinearity. Wind tunnel tests were conducted to compare performances of the DBPME-WEH and a double-beam piezoelectric wind energy harvester (DBP-WEH) that does not comprise the magnet-induced nonlinearity. The results reveal that compared to the DBP-WEH, the critical wind speed to activate the galloping vibration of DBPME-WEH can be reduced up to 41.9%. Thus, the results corroborate the significant performance enhancement by the DBPME-WEH. It can also be found that the distance of the two magnets affects the performance and the distance that achieves the weakly bistable nonlinearity is beneficial to energy harvesting in reducing the critical wind speed and improving the output voltage.
The effect of phase purification on photovoltaic performance of perovskite solar cells
Authors: Qi Xingnan , Tan Furui , Gao Yueyue , Wu Tianli , Liu Rong , Dong Chen , Yue Gentian , Li Shengjun , Zhang Lisheng
Published: November 2019

Organic-inorganic hybrid perovskite solar cells (PSCs) have witnessed a rapid rising in power conversion efficiency (PCE) over the past few years; however, they still suffer from recombination loss via interface defects in perovskite films. In this study, we implement an efficient phase purification strategy by incorporating isopropyl alcohol (IPA) post-treatment of perovskite films that reduces defect states and improves charge transport. It is found that the DMSO-PbI2-MAI complex in the perovskite film is eliminated after IPA post-treatment. A suit of opto-electric characterizations demonstrates that the nonradiative recombination is greatly diminished, and charge extraction is effectively boosted in the modified perovskite films. The perovskite solar cells with phase-pure MAPbI3 achieve an impressively larger PCE of 18.78% than that of 17.1% for the control devices. Our work presents a facile and efficient path to performance improvement of PSCs.

Published: November 2019

Rice with double mutation of starch synthase IIIa and branching enzyme IIb (ss3a/be2b) has much higher amounts of apparent amylose and resistant starch (RS) than usual varieties. In this study, we conducted two randomized, single-blind, crossover trials to investigate the effect of single ingestion of two processed foods composed of ss3a/be2b mutant rice on postprandial blood glucose and insulin response in healthy adults, compared to those of usual cultivar. In trial 1, of ingestion of rice crackers, the incremental area under the curves of glucose (IAUCglc) and insulin (IAUCins) in RS group was significantly lower than in the control group. In trial 2, of the ingestion of cooked rice, IAUCglc in the RS group was significantly lower than in the control group. These results showed that the ss3a/be2b-mutant rice cracker and cooked rice having high RS can attenuate postprandial blood glucose and insulin response.

In order to take full advantage of the three-dimensional digital design data and solve the traditional construction schemes’ problems better, characteristics of three-dimensional digital data and the shortcomings of traditional construction management methods in the paper are analyzed. The organization management mode of 3D digital results is studied to construct a full information 3D model library by combing the relationship between models, attributes, documents, drawings, etc. On the basis of this, combined with the construction process of transmission engineering, a three-dimensional auxiliary construction application platform for transmission engineering based on three-dimensional digital design results is established. Through the software platform to manage, process, analyze and mine massive data, on the one hand, the integration, interaction and sharing of multi-source heterogeneous data are realized; on the other hand, the three-dimensional digital technology is applied to the construction process to realize the three-dimensional visualization of the construction process of the transmission engineering, thus providing a new solution for solving the construction problem.

Authors: Wang Kun , Xu Lamei , Lv Cong
Published: November 2019

In order to optimize makespan and total tardiness for re-entrant hybrid flow shop scheduling problems simultaneously, this paper proposes a novel Shuffled Frog Leaping Algorithm. The algorithm relies on the lexicographic method to process total tardiness and makespan. A suitable crossover operator is introduced. During the searching process of memeplex, instead of worst solution, multiple best solutions are used to generate new solutions. Further with that, the process of generating random solution is replaced with the neighborhood search. Then as indicated by the simulation based on a group of instances, the novel SFLA is superior in addressing hybrid flow shop scheduling problem.

Sales forecast is an indispensable link in the business activities of enterprises, and the accuracy of prediction is directly related to the effectiveness of enterprise sales and operation activities. In order to improve the prediction accuracy, a sales forecasting model based on LSTM is proposed. The model uses SA to optimize the initial connection weights of LSTM neural network, which solves the problem that the LSTM neural network converges to the local optimal, thus improving the network performance, and then makes an empirical analysis of the construction of the sales forecasting model based on SA-LSTM. The results show that the sales forecasting model improves the prediction accuracy, also reduces the number of iterations, and obtains a good prediction effect.

Authors: Hanafi R , Mangngenre S , Asmal S , Setiawan I , Gloryantho C
Published: November 2019

Production scheduling in the industrial sector has a crucial role as the optimization of sources. The companies attempt to have an effective and efficient scheduled to increase the productivity with minimum lead time and cost. The objective of this research is to determine the production schedule of the machines at the minimum level in a manufacturing company to obtain the minimum makespan value. The planning with minimum makespan value will implement in the production process. Production scheduling performed by a PVC pipe factory named PT J during the time based on the longest production time. During the production process, ineffective production planning usually occurred, which caused longer lead time to create a massive production. This research aims to provide the optimal solution for appropriate job sequence to obtain the lowest makespan value as a result. In this research, the authors use two comparative methods, namely Campbell Dudek Smith (CDS) method and Dannebring method to determine the optimal job sequence. According to data processing, by implementing those methods, it obtained the makespan results.

SSM is a large training unit, which focuses on selling the spare parts for the vehicle. Their current problems were the unwell-organized warehouse layout and the lack of distance of the shelves causing the warehouseman facing the difficultness in terms of inventorying the goods management. The overstocked supply usually occurs at the end of the year because of oversupply. This study used the ABC classification method for the rearrangement of their facility layout based on the demand. As a result, brake pad, outer tire, and engine oil, which were classified in A group (fast-moving), must be relocated closer to the access gate. By this arrangement, it could minimize the movement of the personnel up to 133,318.55 m annually. Moreover, using the Economic Order Quantity (EOQ) method, the order period, safety stock, and Re-Order Point (ROP) could be optimized, and the total supply would minimize cost.

A research was carried out to study the morphophysiological response of cocoa plant leaves to different application of microbes formulation in the farmer’s cocoa plantations in Gantarangkeke village, Gantarangkeke district, Bantaeng Regency, South Sulawesi Province from July to December 2016. The experiment was set using Randomized Block Design with nine combinations of dosages and frequencies of the application of microbe formulation as treatments. The formula was sprayed on cocoa leaves using bio-mineral liquid fertilizer with dosages of 0.5, 1.0, and 1.5 mL.L-1 applied once, twice and three times during the experiment. The first application was at the start of the experiment, and the second was at the age of 2 months after planting, respectively. For the three times application treatment, plants were sprayed by the formula every two months. The experiment used three replications, and each experimental unit consisted of four selected plants which were relatively uniform. Results show that the application of microbial formulations through leaves could increase some morphophysiological properties of the leaves of cocoa plants. The application of microbial formulations of 1.5 mL.L-1 of water every two months during the study showed an increase in leaf area growth, leaf water content, chlorophyll a, b and total chlorophyll content of cocoa leaves.

Walanae Protection Forest Management Unit (KPHL) is one of the early Forest Management Unit (KPH) that implementing a forest partnership scheme. There is a community empowerment program through the agroforestry partnership group in the Minangatellue village, Maniangpajo district, Wajo regency with an area of 25 ha. KPH has not often experienced problems in the development of institutional partnership of farmer groups. Many things cover the birth of these obstacles. One of them is how to focus on the agreed principles in the management of the forest partnership scheme. The objective of this study is to analyze the performance of the forest partnership scheme management in the KPHL area. The data obtained were identified and reviewed through a table of criteria and indicators developed by researchers based on four partnership criteria formulated by Piltan and Sowlati and reviewing the text of the cooperation agreement between partners. The results of the performance evaluation show that the value of the average index of the process, the product and the result is 1.9. The value of the index is in the middle category, which means that the implementation of the agroforestry forest partnership scheme management is not good enough. We identified some root problems such as the absence of direct communication with the district government, the absence of decision-making related to the operational activities of the partnership, the absence of an agreement to share unexpected risks and lack of improvement in human resources capacity.
