Controlled orientation of liquid-crystalline polythiophene semiconductors for high-performance organic thin-film transistors

The silane self-assembled monolayer (SAM) modification of a SiO2 gate dielectric surface improved the molecular ordering of organic channel semiconductor in organic thin-film transistors (OTFTs), leading to a significant improvement in transistor performance. Mobility of up to 0.18cm2∕Vs (current on∕off ratio of 107) was obtained for OTFTs with a liquid-crystalline polythiophene semiconductor built on an octyltrichlorosilane-modified SiO2 gate dielectric layer, a 450 times improvement over those built on a nonmodified dielectric layer. The mobility enhancement was attributed to the edge-on orientation of the polythiophene molecules induced by the silane SAM layer as deduced from the crystal domain structures in the atomic force microscopic images.
A 20-GHz PLL With 20.9-fs Random Jitter

This article describes an integer-<inline-formula> <tex-math notation="LaTeX">$N$ </tex-math></inline-formula> phase-locked loop (PLL) that incorporates a phase detector sampling both the rising and falling edges of the reference clock. The circuit also uses a new retiming method in the feedback divider. Optimized for the reference and oscillator phase noise and fabricated in the 28-nm CMOS technology, the experimental prototype achieves an rms jitter of 20.9 fs integrated from 10 kHz to 40 MHz with a spur level of −66 dBc while consuming 12 mW of power.
An Ensemble Model for Consumer Emotion Prediction Using EEG Signals for Neuromarketing Applications

Traditional advertising techniques seek to govern the consumer’s opinion toward a product, which may not reflect their actual behavior at the time of purchase. It is probable that advertisers misjudge consumer behavior because predicted opinions do not always correspond to consumers’ actual purchase behaviors. Neuromarketing is the new paradigm of understanding customer buyer behavior and decision making, as well as the prediction of their gestures for product utilization through an unconscious process. Existing methods do not focus on effective preprocessing and classification techniques of electroencephalogram (EEG) signals, so in this study, an effective method for preprocessing and classification of EEG signals is proposed. The proposed method involves effective preprocessing of EEG signals by removing noise and a synthetic minority oversampling technique (SMOTE) to deal with the class imbalance problem. The dataset employed in this study is a publicly available neuromarketing dataset. Automated features were extracted by using a long short-term memory network (LSTM) and then concatenated with handcrafted features like power spectral density (PSD) and discrete wavelet transform (DWT) to create a complete feature set. The classification was done by using the proposed hybrid classifier that optimizes the weights of two machine learning classifiers and one deep learning classifier and classifies the data between like and dislike. The machine learning classifiers include the support vector machine (SVM), random forest (RF), and deep learning classifier (DNN). The proposed hybrid model outperforms other classifiers like RF, SVM, and DNN and achieves an accuracy of 96.89%. In the proposed method, accuracy, sensitivity, specificity, precision, and F1 score were computed to evaluate and compare the proposed method with recent state-of-the-art methods.
Oscillatory Stokes flow in periodic porous media

The unsteady Stokes equations for the microscopic flow in model porous media subject to an oscillatory pressure gradient are solved. The media consist of periodic lattices (SC, BCC, FCC) of spheres ranging from dilute systems with isolated spheres to highly concentrated consolidated media with overlapping spheres. Detailed results are presented for the dynamic permeability and comparisons are made with previously published results, asymptotic limits, and approximate theories. The wave speed and attenuation rate for acoustic waves are evaluated.
Effects of surface ligands on energetic disorder and charge transport of P3HT:CdSe hybrid solar cells

In this work, the effects of surface ligands of cadmium selenide (CdSe) nanocrystals on energetic disorder and charge transport of poly (3‐hexylthiophene‐2,5‐diyl):cadmium selenide (P3HT:CdSe) hybrid bulk heterojunction solar cells were studied. Photo‐induced current transient spectroscopy (PICTS) was employed to quantitatively characterize the trap state energies in P3HT:CdSe hybrid solar cells from pyridine (Py) and tert‐butylthiol (tBT) treated CdSe nanocrystals. A data processing workflow to extract the trap emission spectra was implemented in the form of solving an inverse problem with regularization techniques. We observed significant differences in the trap state distribution in P3HT:CdSe(tBT) compared to P3HT:CdSe(Py) solar cells, and we found that devices based on P3HT:CdSe(Py) had deeper level trap states. Additionally, transient photoconductivity measurements were performed on P3HT:CdSe solar cells for the purpose of examining the effects of ligands on charge transport. The results were self‐consistent with PICTS analysis in that P3HT:CdSe(tBT) devices exhibited a greater than three‐fold enhancement in carrier mobility relative to P3HT:CdSe(Py) devices, which we attributed to a decreased depth of trap states.
THE EFFECT OF IMPLANTABLE TRANSDUCERS ON MIDDLE EAR TRANSFER FUNCTION — A COMPARATIVE NUMERICAL ANALYSIS

Several types of middle ear implants (MEIs) have been invented as an alternative to conventional hearing aids for the rehabilitation of sensorineural hearing loss. Temporal bone and clinical studies have shown that the implantation of MEIs’ transducers influences middle ear transfer function. But there is little comparative data available about these influences. We conducted comparative studies on the influences of three principal types of MEI transducers in respect to their attachment points on the ossicular chain. To aid the investigation, a human middle ear finite element model was constructed. The model was built based on a complete set of micro-computerized tomography section images of a human ear by reverse engineering technology. The validity of the developed model was verified by comparing the motions obtained by this model with published experimental measurements on human temporal bones. The results show that the eardrum driving transducer (EDT) and the floating mass transducer (FMT) decrease stapes displacement prominently at high frequencies. The greater these transducers’ mass, the smaller is the displacement of the stapes footplate. In contrast, the incus body driving transducer (IBDT) decreases stapes displacement severely at low frequencies, and its adverse effect on residual hearing increases with increasing stiffness of the IBDT’s driving rod.
Intelligent redundant measuring circuit with primary circuit error detection

Differential amplifiers in measuring systems are often exposed to external factors, which may lead to disturbance of their proper operation. Due to the capabilities of microprocessor systems, the intelligent algorithms work well in systems for diagnosing circuit errors such as a short circuit or a circuit break. A group of switches is connected to the primary circuit which are designed to check the condition of the measurement system branches. If an error is detected, the measurement of voltage is switched to the additional system. ( Inteligentny
Thematic review series: The Immune System and Atherogenesis. Cytokine regulation of macrophage functions in atherogenesis Published, JLR Papers in Press, July 1, 2005. DOI 10.1194/jlr.R500009-JLR200

This review will focus on the role of cytokines in the behavior of macrophages, a prominent cell type of atherosclerotic lesions. Once these macrophages have immigrated into the vessel wall, they propagate the development of atherosclerosis by modifying lipoproteins, accumulating intracellular lipids, remodeling the extracellular environment, and promoting local coagulation. The numerous cytokines that have been detected in atherosclerosis, combined with the expression of large numbers of cytokine receptors on macrophages, are consistent with this axis being an important contributor to lesion development. Given the vast literature on cytokine-macrophage interactions, this review will be selective, with an emphasis on the major cytokines that have been detected in atherosclerotic lesions and their effects on properties that are relevant to lesion formation and maturation. There will be an emphasis on the role of cytokines in regulating lipid metabolism by macrophages. We will provide an overview of the major findings in cell culture and then put these in the context of in vivo studies.
Closed-form solution for generalized Vasicek dynamic term structure model with time-varying parameters and exponential yield curves

In this paper I study a generalized Vasicek dynamic term structure model with time-varying parameters, where the short rate r is unbounded and the time to maturity for the exponential yield curve model is an exponential function of the short rate. Closed-form solutions are derived for two cases by function analysis technique, with the classical Vasicek equation used as a special case. The methods employed in this paper may have significance in the study of other aspects of finance.
On the energy spectrum of relativistic electrons in the Crab Nebula

A model of pulsars by Sturreck predicts that pulsars may be sources of large numbers of relativsitic electrons and positrons created by photon decay of high-energy r-rays in the strong magnetic fields of the pulsars. This model is investigated in detail to obtain the energy spectrum of the particles. An energy spectral index of 3/2 is found for the mildly relativistic electrons, which is in extent agreement with the spectral index of electrons that must be injected into the Crab Nebula to give the observed radio spectrum via synchrotron radiation. Further, their number is sufficient to explain the overall energeties of the Crab Nebula. The energies of the secondary particles are sufficient to explainthe optical emission, but not the X-ray flux, via a synchrotron preceas. However, their number aad spectrum strongly suggest that they may be the seed particles that arm accelerated to higher energies before radiation X-rays. (auth)
A Bowtie for a Beast: Overloading, Eta Expansion, and Extensible Data Types in F⋈

The typed merge operator offers the promise of a compositional style of statically-typed programming in which solutions to the expression problem arise naturally. This approach, dubbed compositional programming, has recently been demonstrated by Zhang et al. Unfortunately, the merge operator is an unwieldy beast. Merging values from overlapping types may be ambiguous, so disjointness relations have been introduced to rule out undesired nondeterminism and obtain a well-behaved semantics. Past type systems using a disjoint merge operator rely on intersection types, but extending such systems to include union types or overloaded functions is problematic: naively adding either reintroduces ambiguity. In a nutshell: the elimination forms of unions and overloaded functions require values to be distinguishable by case analysis, but the merge operator can create exotic values that violate that requirement. This paper presents F⋈, a core language that demonstrates how unions, intersections, and overloading can all coexist with a tame merge operator. The key is an underlying design principle that states that any two inhabited types can support either the deterministic merging of their values, or the ability to distinguish their values, but never both. To realize this invariant, we decompose previously studied notions of disjointness into two new, dual relations that permit the operation that best suits each pair of types. This duality respects the polarization of the type structure, yielding an expressive language that we prove to be both type safe and deterministic.
Thermally compensated aluminum nitride Lamb wave resonators for high temperature applications

In this letter, temperature compensation for aluminum nitride (AlN) Lamb wave resonators operating at high temperature is presented. By adding a compensating layer of silicon dioxide (SiO2), the turnover temperature can be designed for high temperature operation by varying the normalized AlN film thickness (hAlN/λ) and the normalized SiO2 film thickness (hSiO2/λ). With different designs of hAlN/λ and hSiO2/λ, the Lamb wave resonators were well temperature-compensated at 214 °C, 430 °C, and 542 °C, respectively. The experimental results demonstrate that the thermally compensated AlN Lamb wave resonators are promising for frequency control and sensing applications at high temperature.
Predicting Structure in Sparse Matrix Computations

Many sparse matrix algorithms---for example, solving a sparse system of linear equations---begin by predicting the nonzero structure of the output of a matrix computation from the nonzero structure of its input. This paper is a catalog of ways to predict nonzero structure. It contains known results for some problems, including various matrix factorizations, and new results for other problems, including some eigenvector computations.
Augmented Intelligence with Interactive Voronoi Treemap for Scalable Grouping: a Usage Scenario with Wearable Data

Interactive Voronoi Treemaps have been proposed to support arrangement and grouping tasks of data with snippet image representations. They rely on time-consuming manual actions to group data and cannot display more than a hundred images without occlusion. We propose visualizations designed to manage images visibility, evaluate group homogeneity, and shorten grouping task completion time while keeping control. It is supported by an automatic classifier forming an augmented intelligence system to tackle arrangement and grouping tasks at scale. We propose the usage scenario of a clinician using Interactive Voronoi Treemaps to group wearable data based on sleep visual patterns.
Determination of wall boundary conditions for high-speed-ratio direct simulation Monte Carlo calculations

A procedure for determining the velocity distribution function for the molecules that are reflected from an element of surface when a vehicle is moving in the transition or free-molecule flow regimes at high speed ratios is described. This distribution function could be used as the boundary condition for DSMC calculations. The method uses measurements of the momentum accommodation coefficients to determine the parameters for the Nocilla model of the reflected velocity distribution function. The use of this function as a boundary condition with the DSMC method would yield more accurate predictions of flow fields than are presently obtained using the assumption of diffuse scattering from the body surface. Several sets of Nocilla model parameters are determined as examples of the application of the procedure.
AN EXISTENCE THEOREM FOR DIFFERENCE POLYNOMIALS1

Introduction. The abstract varieties (also called manifolds) of difference algebra [2], [3] have not heretofore had a realization as sets of functions comparable to the realization provided for differential manifolds by the analytic existence theorem for differential equations (see [4], particularly p. 23). It is the purpose of this Note to provide such a realization by means of an existence theorem yielding solutions of difference equations as complex-valued functions defined, except for isolated singularities, on the non-negative real axis. Since the abstract varieties consist by definition of elements lying in integral domains, these functions are required to generate difference rings which are integral domains. This distinguishes the existence theorem from the mere use of the difference equation as a recursion relation. In addition, the functions studied here are piecewise analytic, though discontinuous. There is no reason to regard the class of functions selected in this Note as definitive: other choices may better repay fur-ther study. It would,

2022 WUOF/SIU International Consultation on Urological Diseases: Genetics and Tumor Microenvironment of Renal Cell Carcinoma

Renal cell carcinoma is a diverse group of diseases that can be distinguished by distinct histopathologic and genomic features. In this comprehensive review, we highlight recent advancements in our understanding of the genetic and microenvironmental hallmarks of kidney cancer. We begin with clear cell renal cell carcinoma (ccRCC), the most common subtype of this disease. We review the chromosomal and genetic alterations that drive initiation and progression of ccRCC, which has recently been shown to follow multiple highly conserved evolutionary trajectories that in turn impact disease progression and prognosis. We also review the diverse genetic events that define the many recently recognized rare subtypes within non-clear cell RCC. Finally, we discuss our evolving understanding of the ccRCC microenvironment, which has been revolutionized by recent bulk and single-cell transcriptomic analyses, suggesting potential biomarkers for guiding systemic therapy in the management of advanced ccRCC.
Smoothie Drinks: Possible Source of Resistant and Biofilm-Forming Microorganisms

Smoothie drinks are currently very popular drinks sold especially in fast food establishments. However, smoothies are a significant source of microorganisms. The aim of this study was to evaluate the microbiological quality of smoothies purchased in Eastern Bohemia. A higher prevalence of mesophilic aerobic bacteria (5.4–7.2 log CFU/mL), yeast (4.4–5.9 log CFU/mL) and coliform bacteria (3.1–6.0 log CFU/mL) was observed in vegetable smoothies, in which even the occurrence of enterococci (1.6–3.3 log CFU/mL) was observed. However, the occurrence of S. aureus, Salmonella spp. and Listeria spp. was not observed in any samples. Nevertheless, antimicrobial resistance was observed in 71.8% of the isolated strains. The highest level of resistance was found in isolates from smoothie drinks with predominantly vegetable contents (green smoothie drinks). Considerable resistance was observed in Gram-negative rods, especially to amoxicillin (82.2%) and amoxicillin with clavulanic acid (55.6%). Among enterococci, only one vancomycin-resistant strain was detected. The vast majority of isolated strains were able to form biofilms at a significant level, which increases the clinical importance of these microorganisms. The highest biofilm production was found in Pseudomonas aeruginosa, Kocuria kristinae and Klebsiella pneumoniae. Overall, significant biofilm production was also noted among isolates of Candida spp.
A Geometric Approach

We consider a general pursuit-evasion differential game with three or more pursuers and a single evader, all with simple motion (fixed-speed, infinite turn rate). It is shown that traditional means of differential game analysis is difficult for this scenario. But simple motion and min-max time to capture plus the two-person extension to Pontryagin’s maximum principle imply straight-line motion at maximum speed which forms the basis of the solution using a geometric approach. Safe evader paths and policies are defined which guarantee the evader can reach its destination without getting captured by any of the pursuers, provided its destination satisfies some constraints. A linear program is used to characterize the solution and subsequently the saddle-point is computed numerically. We replace the numerical procedure with a more analytical geometric approach based on Voronoi diagrams after observing a pattern in the numerical results. The solutions derived are open-loop optimal, meaning the strategies are a saddle-point equilibrium in the open-loop sense.
List 2-distance Δ + 3-coloring of planar graphs without 4,5-cycles

Let χ 2 ( G ) and χ l 2 ( G ) bethe2-distancechromaticnumberandlist2-distance chromatic number of a graph G , respectively. Wegner conjectured that for each planar graph G with maximum degree Δ at least 4, χ 2 ( G ) ≤ Δ + 5 if 4 ≤ Δ ≤ 7, and χ 2 ( G ) ≤ (cid:3) 3 Δ 2 (cid:4) + 1 if Δ ≥ 8. Let G be a planar graph without 4,5-cycles. We show that if Δ ≥ 26, then χ l 2 ( G ) ≤ Δ + 3. There exist planar graphs G with girth g ( G ) = 6 such that χ l 2 ( G ) = Δ + 2 for arbitrarily large Δ . In addition, we also discuss the list L ( 2 , 1 ) -labeling number of G , and prove that λ l ( G ) ≤ Δ + 8 for Δ ≥ 27.
Occurrence of ectoparasites on Nile Tilapia (Oreochromis niloticus) from South Sulawesi Lakes, and Aquaculture facility

Nile tilapia, whether cultivated or living in the wild, is susceptible to various parasite’ infection. A parasitology investigation was conducted to identify parasites of Nile tilapia in Lakes and from aquaculture facilities. The fish examined from aquaculture facility in Bantaeng has a total length of 15 to 20 cm (n= 30) and the hybrid-tilapia from a mini hatchery consist of three groups of fish size. Fish from Towuti Lake range from 7.0 to 21.8 cm in total length (n= 35), and the fish from Tempe Lake range from 10 to 16 cm in total length (n= 40). Parasites found from Nile tilapia in Tempe Lake were monogenean: Cichlidogyrus spp. and Scutogyrus longicornis, and Crustacea; Argulus indicus. Parasites found from Aquaculture facility in Bantaeng were Trichodina magna, Gyrodactylus cichlidarum, Cichlidogyrus spp. and S. longicornis. Trichodinids from Nile tilapia in Towuti Lake were Paratrichodina sp. , T. heterodentata, Trichodinella sp. , and Tripartiella sp. Parasites found from red hybrid tilapia were Trichodina spp. , Cichlidogyrus spp. , and G. cichlidarum. The prevalence and mean intensity of the parasite’s infection were discussed. In this study, we present for the first time the presence of some genera of Trichodinids in Nile tilapia in Towuti Lake.
Scalloped Hammerhead (Sphyrna lewini) Movement Behavior toward Diver in Banda Waters, Maluku

Shark diving tourism opens opportunities to study shark behavior towards diver. As one of the popular attractions for the marine tourism in Indonesia, shark diving play significant role for the conservation in the eastern part of Indonesia. Banda Sea, as well as Morotai, Derawan, Raja Ampat, Nabire and Teluk Cenderawasih, Bali, Lombok, Komodo, and Gorontalo, is famous for its shark diving attraction. Despite its famous status as a tourism attraction, little is known about the behavior of scalloped hammerhead shark during the interaction with Self-Contained Underwater Breathing Apparatus (SCUBA) diver. The information of scalloped hammerhead shark movement behavior during interaction with SCUBA diver is important for developing ecological assessment, safe diving practice, and shark tourism carrying capacity. This research involves DOV (Diver Operated Video) to record the movement patterns of shark while interacting with SCUBA Diver. Evaluation of approximately 457 photos and 32 videos of the Sphyrna lewini during 14 days of observations has been analyzed during SCUBA diving shows the most common shark agonistic display: pectoral fins depression - apart from other displays such as tail slapping, flank displaying, charging, snout raise, and jaw gapping. It also reveals three (3) new shark agonistic postures which were never been recorded previously: charging, snout raise, and jaw gapping. This study showed that there are consistent behaviors observed while meeting with SCUBA divers and this may be beneficial for development of safety diving management, as well as conservation efforts.
