High-Frequency Rectifiers Based on Organic Thin-Film Transistors on Flexible Substrates

Rectifier circuits featuring low threshold voltages and high cutoff frequencies based on p-channel organic thin-film transistors (TFTs) have been designed, fabricated and characterized. The TFTs and circuits were fabricated by shadow-mask lithography on flexible plastic substrates using the vacuum-deposited small-molecule organic semiconductor dinaphtho[2,3-b:<inline-formula> <tex-math notation="LaTeX">$2^\prime $ </tex-math></inline-formula>,<inline-formula> <tex-math notation="LaTeX">$3^\prime $ </tex-math></inline-formula>-f]thieno[3,2-b] thiophene (DNTT). The TFTs have a gate dielectric with a thickness of 5.3 nm and a channel length of 10 <inline-formula> <tex-math notation="LaTeX">$\mu \text{m}$ </tex-math></inline-formula>. The study considers the frequency characteristics of diode-connected transistors (transdiodes) and adopts circuit techniques from silicon CMOS technology, namely single-stage and multistage dynamic-threshold-compensated differential rectifiers. The characterization of the rectifier circuits indicates cutoff frequencies up to 4.75 MHz at a peak-to-peak input voltage of 3 V for transdiodes, up to 32 MHz at a peak-to-peak input voltage of 1.5 V for single-stage differential rectifiers and up to 7.5 MHz at a peak-to-peak input voltage of 1.5 V for two-stage rectifiers. The efficiency is 25% for a load of 10 <inline-formula> <tex-math notation="LaTeX">$\text{M}\Omega $ </tex-math></inline-formula> and below 1% for a load of 1 <inline-formula> <tex-math notation="LaTeX">$\text{M}\Omega $ </tex-math></inline-formula>.
Effects of Charge Quantity Induced by Different Forming Methods in Solid Electrolyte GeSO-Based Resistance Switching Device With Copper Electrode

In this article, two different resistance switching (RS) behaviors are demonstrated after using dc and constant bias stressed (CBS) forming methods in GeSO-based resistive random access memory (RRAM) with a copper top electrode. Electrical measurements show that the amount of charge during the forming process significantly affects their RS behaviors. Large memory windows appear when applying CBS forming, while traditional dc forming did not exhibit such characteristics. Both current–voltage ( $I-V$ ) fitting and high temperature retention test are used to further investigate the RS property and verify the stability. Finally, conduction models for devices using these different forming methods are also proposed to better illustrate their different conducting behaviors in the GeSO-based RRAM device.
Fast High Dynamic Range MRI by Contrast Enhancement Networks

HDR-MRI is a sophisticated non-linear image fusion technique for MRI which enhances image quality by fusing multiple contrast types into a single composite image. It offers improved outcomes in automatic segmentation and potentially in diagnostic power, but the existing technique is slow and requires accurate image co-registration in order to function reliably. In this work, a lightweight fully convolutional neural network architecture is developed with the goal of approximating HDR-MRI images in real-time. The resulting Contrast Enhancement Network (CEN) is capable of performing near-perfect ($\text{SSIM} =0.98$) 2D approximations of HDR-MRI in 10ms and full 3D approximations in 1s, running two orders of magnitude faster than the original implementation. It is also able to perform the approximation ($\text{SSIM} =0.93$) with only two of the three contrasts required to generate the original HDR-MRI image, while requiring no image co-registration.
Automatic segmentation of head-neck organs by Multi-mode CNNs for radiation therapy

Objective: Accurate and fast automatic segmentation of organs is a key step for efficient planning for radiation therapy. In this paper, we propose the Multi-mode CNNs, which is for accurate and fast automatic segmentation of mandible, parotid glands, brainstem, optic nerves, cerebellum, eyes, lens, pituitary, thyroid, temporal lobes, brain and head respectively in 3D CT image of head and neck.Methods: The proposed Multi-mode CNNs consist of three convolutional neural networks. The first CNN is a simple classification network to distinguish slices of head and neck. It accelerates the next step by reducing the search space. The second network is a 3DCNN for locating the region of interest (ROI) of organs. It can enhance the robustness of the algorithm to CT images from different hospitals. The third network is a full convolution network (FCN) based on U-Net. This is a pixel-wise detailed segmented network to classify voxels in a region of interest and generate segmentation results. We used public and clinical datasets to evaluate our algorithm. The public datasets are from the MICCAI 2015 Head and Neck Auto Segmentation Grand Challenge. For the private datasets, we collected 3D CT images of 88 patients from A and B Hospital.Results: For the public datasets, our segmentation results of the nine organs in the challenge surpassed the first rank. For the private datasets, clinical trials have proved that it is effective for real image data in different hospitals. The average total segmentation time for one patient with above whole organs is less than one minute, which indicates proposed method having clinical value.Conclusion: The proposed Multi-mode CNNs can be used to accurate and fast automatic segmentation of organs in radiation therapy. It can assist doctors in outlining the organs during the planning of radiation therapy in the clinic.
The distribution, abundance and conservation status of riverine frogs in Kosciuszko National Park

A survey was conducted of the distribution and abundance of stream-breeding frogs within Kosciuszko National Park, with particular emphasis upon locating new populations of the endangered Spotted Tree Frog Litoria spenceri. Twenty-five streams were sampled within the Park. Populations of L. spenceri ware located on two streams, including one new locality for the species. This constiiutes only the second population of this species known from New South Wales. Three other riverine species ware located during the survey. The endangered Booroolong Frog L. boorooiongensis was located only along one stream and could not be found at the two historic sites within the Park. The overall abundance of riverine frogs was found to be relatively low. Frogs were found at significantly fewer sites affected by modified stream flows from the Snowy Mountains Scheme, than comparatively undisturbed sites. The potential impacts of these changes and introduced fish upon the distribution and abundance of riverine frogs within the .
Correlates of Google Search Rankings for Spine Surgeons: An Analysis of Academic Pedigree, Social Media Presence, and Patient Ratings.

STUDY DESIGN Prospective observational study. OBJECTIVE The objective of this study is to identify correlates of search ranking among academic pedigree, online ratings, and social media following. SUMMARY OF BACKGROUND DATA Patients increasingly rely on online search in selecting healthcare providers. When choosing a spine surgeon, patients typically value surgical skill and experience as well as demeanor/bedside manner. It is unclear whether current search engine ranking algorithms reflect these preferences. METHODS A Google.com search for the top 25 spine surgeon websites by search ranking was conducted for each of the largest 25 American cities. Resulting websites were then perused for academic pedigree, experience, and practice characteristics. Surgeons' research output and impact were then quantified via number of publications and H-index. Online ratings and followers in various social media outlets were also noted. These variables were assessed as possible correlates of search ranking via linear regression and multivariate analyses of variance. RESULTS A total of 625 surgeons were included. Three categorical variables were identified as significant correlates of higher mean Google search ranking-orthopaedics (vs. neurosurgery) as a surgical specialty (p = 0.023), board certification (p = 0.024), and graduation from a top 40 residency program (p = 0.046). Although the majority of the identified surgeons received an allopathic medical education, there was no significant difference in the mean rank of surgeons who had an MD vs. DO medical degree (p = 0.530). Additionally, none of the continuous variables collected, including years in practice (p = 0.947), publications (p = 0.527), H-index (p = 0.278), social media following such as on Facebook (p = 0.105), or online ratings such as on Healthgrades (p = 0.080), were significant correlates of Google search ranking. CONCLUSIONS Google search rankings do not always align with patient preferences, currently promoting orthopaedic over neurosurgical specialists, graduation from top residency programs and board certification, while largely ignoring academic pedigree, research, social media presence, and online ratings. LEVEL OF EVIDENCE 3.
The effects of microRNA-126 reduced inflammation and apoptosis of diabetic nephropathy through PI3K/AKT signalling pathway by VEGF

Abstract Gene expression microarray and reverse transcription-quantitative polymerase chain reaction (RT-qPCR) was used to measure the expression of miR-126. In model of diabetic nephropathy, we demonstrated that miR-126 expression was down-regulated, compared with control group. Down-expression of miR-126 promoted cell apoptosis and increased inflammation (as indicated by the levels of IL-1β, IL-6, IL-18 and TNF-α) of diabetic nephropathy in vitro. miR-126 over-expression led to significant inhibition of cell apoptosis and suppressed inflammation (IL-1β, IL-6, IL-18 and TNF-α). However, the down-expression of miR-126 suppressed the protein expression of VEGF, PI3K and p-AKT in diabetic nephropathy in vitro. On the contrary, over-expression of miR-126 induced the protein expression of VEGF, PI3K and p-AKT in diabetic nephropathy in vitro. The inhibition of VEGF increased the effect of miR-126 down-expression on apoptosis and inflammation in diabetic nephropathy in vitro. We investigated the specific function of miR-126 in patients with diabetic nephropathy and its possible mechanism.
Understanding Online Impulse Buying Behavior in Social Commerce: A Systematic Literature Review

In the past few years, online impulse purchase has garnered attention from researchers in various fields, especially noted in the relatively new field of social commerce (S-commerce). This interactive envronment is a full of impulse buying stimulators. However, no previous studies have been conducted to evaluate the status of the research about online impulse buying behavior (IBB) in S-commerce. Hence, the authors reviewed studies published between 2005 and 2019, to gain an insight into IBB. The authors used an input-moderator-mediator-output model for identifying and classifying factors that influence consumer’s online IBB in S-commerce. The authors adopted a review protocol that involved two stages (i.e., automatic and manual), and identified 68 studies that addressed online IBB, of which 24 studies focused on IBB in S-commerce. The systematic review results indicated that survey-based studies (83%) and experiment methods (17%) were prevalent in online IBB in S-commerce. The authors also noted that a majority of existing studies adopted stimulus-organism-response. In this study, the factors that influence online IBB in S-commerce were classified, and a causal-chain framework for online impulse buying was developed. Finally, the authors made recommendations for future research in this field.
A Revision of the Genus Cystidicola Fischer, 1798 (Nematoda: Spiruroidea) of the Swim Bladder of Fishes

The systematics of the species of the genus Cystidicola Fischer, 1798, parasites of the swim bladder of physostomous fishes, is revised. Cystidicola farionis Fischer, 1798, C. cristivomeri White, 1941, and C. stigmatura (Leidy, 1886) Ward and Magath, 1917, are considered to be the only valid species in the world. These three species are redescribed. Cystidicola farionis is morphologically indistinguishable from C. stigmatura but the two species are tentatively regarded as distinct until more data on their biology are available. Cystidicola brevicauda Fujita, 1939, and C. mesopi Fujita, 1940, are not members of Cystidicola but they cannot be assigned to any other genus. Cystidicola lepisostei Hunter and Bangham, 1933, is a member of Cystidicola but should be regarded as a species inquirendae. Cystidicola minuta Rhodhain and Vuylsteke, 1934, and C. serratus (Wright, 1879) Railliet, 1916, are regarded as species inquirendae of the genus Rhabdochona. The literature on numerous other species assigned at variou.
Seasonal patterns of weight, hematology, and serum characteristics of free-ranging female white-tailed deer in Minnesota

Weights, hematology, and serum profiles of white-tailed does in the central Superior National Forest of northeastern Minnesota were examined year-around to determine seasonal patterns of nutritional condition and metabolism. Deer were initially captured by Clover trap or rocket net. Between 15 February 1989 and 23 January 1990, we recaptured 12 adult (> 1.5 years) female deer 1–9 times each (a total of 59 recaptures) using a radio-controlled capture collar. Monthly weights of deer exhibited a cyclic seasonal pattern. Mean weight declined 22% from February to an annual minimum during May, then steadily increased 45% to a maximum in October. Seasonal patterns were most evident for hemoglobin concentration, red blood cells, packed cell volume, serum total protein, urea nitrogen, creatinine, the urea N to creatinine ratio, triiodothyronine, cortisol, and potassium. Wide seasonal variations of these characteristics were indicative of shifts in the deer's metabolic physiology. Although seasonal metabolic shifts.
Environmental factors shape cloacal bacterial assemblages in great tit Parus major and blue tit P. caeruleus nestlings

Despite their potential ecological and evolutionary importance, factors shaping the composition of bacterial communities in wild vertebrate populations remain poorly understood. The goal of this study was to examine the relative contributions of environmental factors and genetic factors (e.g. species and common origin) to the variation of cloacal bacterial assemblages in wild bird nestlings. We conducted a partial cross-fostering experiment with two passerine species, the great tit Parus major and the blue tit P caeruleus, sharing similar habitats and breeding biology. Nestlings of the two species were exchanged four days after hatching and cloacal bacteria were sampled nine days later. The structure of cloacal bacterial communities was determined by Ribosomal Intergenic Spacer Analysis. Our results showed that each nestling displayed a unique bacterial community. Furthermore, nestlings raised in the same nest shared significantly similar bacterial communities. The similarity of bacterial community was higher among heterospecific siblings raised within the same nest than between biological siblings raised in separate nests. Effects of common origin between species could not be detected and, if present, were dominated by nest-based short-term environmental effects. Our results show that growth conditions within nests and individually based endogenous factors have significant effects on cloacal bacteria assemblages and could affect post-fledging condition.
Influences of CD8+ Tregs on Peripheral Blood Mononuclear Cells from Allergic Rhinitis Patients

CD8+(or CD4+) CD25+fork‐head box transcription factor (Foxp3)+ regulatory T cells (CD8+ or CD4+ Tregs) all play a significant role in immune homeostasis and tolerance. However, the role of CD8+ Tregs in allergic rhinitis (AR) have not been clearly elucidated. The present study was aimed to assess the influence of CD8+ Tregs on peripheral blood mononuclear cells (PBMCs) from AR patients.
Enhancement-/Depletion-Mode TiO2 Thin-Film Transistors via O2/N2 Preannealing

Metal-oxide thin-film transistors (TFTs) promise to enable lightweight and low-power applications, such as ultrathin active matrix displays and low-cost RF identification tags. However, most reported high-performance metal-oxide TFTs contain high-cost indium and gallium elements, leading to constraints in cost-sensitive application. Herein, we present enhancement-/depletion-mode (E-/D-mode) TiO<sub>2</sub> TFTs via <inline-formula> <tex-math notation="LaTeX">$\text{O}_{{2}}/\text{N}_{{2}}$ </tex-math></inline-formula> preannealing of TiO<sub>2</sub> channel material prior to device fabrication process. It is found that the O<sub>2</sub>-annealed TiO<sub>2</sub> TFTs exhibit improved performances compared to N<sub>2</sub>-annealed TiO<sub>2</sub> TFTs, including increased mobility (<inline-formula> <tex-math notation="LaTeX">$\mu $ </tex-math></inline-formula>), higher ON-/OFF-current ratio (I<sub>ON</sub>/I<sub>OFF</sub>), and lower subthreshold swing (SS). This can be attributed to the passivation effects of O<sub>2</sub> annealing, which leads to less oxygen vacancies at the channel and channel/oxide interface. On the other hand, the ionized oxygen vacancies result in the increased electron concentration in N<sub>2</sub>-annealed films and, thus, the negative shift of <inline-formula> <tex-math notation="LaTeX">${V}_{\text {th}}$ </tex-math></inline-formula> in the TFT performance. This article delivers a possible approach to improve oxide TFT performance by passivation of oxygen vacancies. Furthermore, the controlled annealing process has a great potential in the logic inverter applications when both E- and D-mode TFTs are implemented.
A history of weed control in the United States and Canada—a sequel

Abstract The weed science discipline has changed significantly since 1970. New herbicides have been introduced, many herbicide-resistant weeds have been documented, herbicide-resistant crops have been introduced, federal laws affecting pesticides and weeds have been modified, the number of companies discovering and developing herbicides has been drastically reduced, basic studies on weed biology have received more emphasis, and integrated methods of controlling weeds with nonchemical as well as chemical methods have received increasing attention.
An Exploration of Precancer and Post-Cancer Diagnosis and Health Communication Among African American Prostate Cancer Survivors and Their Families

Prostate cancer is the second most common cancer among American men, with Black men at the highest risk for the disease. Few studies have been published on how communication between Black prostate cancer survivors and their family members affect health outcomes and subsequent health communication. The purpose of this study was to understand cancer and health communication among Black prostate cancer survivors and their families before and after disclosing their diagnosis. Through a mixed method design, 11 Black prostate cancer survivors participated from the Southeastern region of the United States, completed questionnaires, and took part in a focus group. The study utilized 4 focus groups of Black prostate cancer survivors ranging in age from 51 to 76 years. Descriptive statistics revealed 91% (n = 10) of participants indicated they could openly discuss health issues in their family and 82% (n = 9) indicated a female relative as the person responsible for teaching about health. An analysis of the transcripts revealed four themes utilizing thematic network: (a) communication over the life course of the prostate cancer survivor, (b) parents’ communication with family, (c) disclosing prostate cancer diagnosis, and (d) treatment options for prostate cancer. Results suggested the participants recognized the importance of discussing prostate cancer with their families to reduce fears and misconceptions about the disease. Through the exploration of cancer and health communication within Black families, solutions can be derived for increasing health behaviors and health knowledge among men.
Supply Chain Management – Models And New Trends

Nowadays, supply chain management is becoming more relevant problematic. Supply chains are complex and dynamic systems in which information, materials and cash flows are interconnected. Each product has its own supply chain, some supply chains can be short and simple and some quite long and complex. Supply chain activities cover everything from product development, sourcing and production to logistics, as well as the information systems needed to coordinate these activities. Considering the numerous activities in the supply chain it is necessary to manage it. Supply chain management (SCM) is the active management of supply chain activities to maximize customer value and achieve a sustainable competitive advantage. The subject of research in this paper will be the models of supply chain management, and at the end of the paper an analyses of new trends of supply chain management will be performed.
Some doubts about (yet another) view of species

I ®nd that I agree with many of the facts that Wu presents but with fewer of the conclusions he draws from them. In particular, I agree that molecular and ecological work suggests that selection, whether natural or sexual, is the most important force shaping species differences. I also agree that `genomes during (or even after) speciation can be quite ``porous''', with some loci ̄owing freely between sympatric taxa and others not at all. [Neither of these facts is, however, terribly novel. The last one in particular has been talked about for quite some time in both the hybrid zone and plant literature (Barton & Hewitt, 1985; Harrison, 1990; Rieseberg & Whitton et al. 1999). ] But I fail to see why these facts pose a profound problem for the biological species concept (BSC), much less demand its `major revision', leaving us with something `close to Darwin's original concept of speciation. ' Indeed I have come to the conclusion that Wu's claims to the contrary hinge on two problems in his analysis. One is that he confuses a straw man with the BSC. The other is that he ignores problems with the alternative Darwinian view of speciation.
Causes and Temporal Patterns of Cotton Fruit Abscission

The causes of cotton fruit abscission were monitored throughout the growing season in three fields as a means of finding patterns in fruit mortality. Almost all fruit abscission occurred during one of two normally distributed pulses. The first pulse was largely the result of insect injury. The second pulse was primarily caused by physical stresses. Although many fruit abscised because of insect injury, much of this shedding did not constitute economic loss because plants could compensate for the damage.
