Light trapping in thin silicon waveguides by plasmon mediated mode coupling

Thin-film solar cells have many advantages over their thick counterparts. However, these cells often exhibit relatively poor light absorption. Efficient light trapping by coupling light into the discrete set of waveguide modes supported by such thin semiconductor films, enhances the absorption significantly. Here, two-dimensional metal nanoparticle arrays on top of a SOI wafer are studied, to investigate the mode coupling mechanism. The 200 nm top Si layer of the SOI wafer acts as an isolated waveguide that functions as a model system for a thin-film solar cell. Analytical calculations and finite-element simulations are used to find the waveguide modes supported by the structure, to determine their dispersion and calculate the absorption enhancement inside the waveguide due to mode coupling. Based on these calculations we describe the coupling mechanism in terms of mode overlap and momentum matching between the incoming light and the waveguide modes. Using a novel soft imprint technique, two-dimensional particle arrays with different particle diameter and pitch are fabricated on top of SOI wafers to experimentally study the mode coupling mechanism. Spectrally resolved total reflection measurements and angle-resolved specular reflection measurements are used to detect light coupling to waveguide modes. A new method to directly probe the insitensity enhancement inside semiconductor layers is presented in which optically active erbium ions that luminesce in the IR are implanted in the waveguide. The PL intensity is used as a measure of the erbium excitation rate. This method is then used to prove that light couples to waveguide modes. By changing the angle of incidence of the pump light, clear distinct peaks are observed for different angles as a result of momentum matching, that are attributed to coupling to well-defined waveguide modes. Motivated by this work, a two-dimensional network of silver nanowires is designed and fabricated to replace ITO as a transparent conducting electrode on optoelectronic devices. By changing the wire dimensions, the resonant behaviour of the wires can be tuned to optimize the transmittance. Transmission measurements and electrical I-V measurements show supernormal optical transmittance, which is higher than for commercially used ITO over the 400− 600 nm spectral range. Also, the electrical resistance of the networks has the potential to beat the ITO when scaled to large areas.
The Sexual Values and Behaviors Discrepancy Model

Founded in theory and empirical research, we developed the Sexual Values and Behaviors Discrepancy Model (SVBDM) as reflective model for counselors to follow in order to assist their clients in safely reducing discrepancies between their ideal and practiced sexual beliefs, values, and behaviors. The SVBDM is a wellness-informed and sex-positive approach to working with clients and is comprised of three steps: Identification and Operationalization of Potential Sexual Issues, Counselor’s Self-Assessment, and Reducing Discrepancies and Maintaining Safety. We note practical implications and potential limitations of this model as well as recommendations for future research.

Advertisement is a medium of communication utilized by organizations in order to convey their intended messages to their targeted audience. It can be divided into two main groups which are digital and physical advertising. As for video advertising which is the chosen business document for this paper, it belongs in the former type. Nowadays, it can be seen that more organizations are inclined towards the utilization of video advertising as it is believed as capable in reaching to maximum number of audiences in no time. Therefore, the rhetorical elements of ethos, pathos, and logos are adapted as the instrument in analysing the selected video advertisement. These aforementioned elements are categorized as appeals which serve different functions and have the ability in helping to increase the persuasiveness level. With that, the objective of this paper is to examine how the rhetorical elements are used in the video advertisement of a hijab brand. As for the findings, it shows that ethos, pathos and logos are being used synergically as the persuasive tools to influence the audience. With the presence of this study, it is hoped that it can shed some light on the effectiveness of implementing these rhetorical elements in video advertisements.
An Investigation of Applications of Hand Gestures Recognition in Industrial Robots

Hand gesture recognition (HGR) is a natural way of Human Machine Interaction and has been applied on different areas. In this paper, we discussed works done in the area of applications of HGR in industrial robots where focus is on the processing steps and techniques in gesturebased Human Robot Interaction (HRI), which can provide useful information for other researchers. We reviewed several related works in the area of HGR based on different methods including sensor based approaches and vision based approaches. After comparing the two types of approaches, we found that 3D vision-based HGR method is a challenging but promising researching area. Then concerning works of implementation of HGR in industrial scenario are discussed in detail. Pattern recognition algorithms that effectively used in HGR like k-means, DTW etc. are briefly introduced as well. Finally, after reviewing some works done in the area of designing gesture set, we proposed several principles in designing industrial hand gesture commands. 
Analyzing Learning Effects in the Newsvendor Model by Probabilistic Methods

In this paper, we use probabilistic methods to analyze learning effects in a behavioral experiment on the newsvendor model. We argue why we should believe that suggested orders follow a multinomial logit distribution, and use the single parameter in that model to extract information on learning effects. We revisit the data, analyzed previously by Bolton et al. (2012), and show that our model predicts the pull-to-center effect in these experimental data very well.
WITH ASSUMPTION DENSITY OF C1(Rn)

In this paper, we present a sufficient condition for the density of C 0 (R ) in W 1,p(x)(Rn) with assumption that p(x) satisfying a condition such that C1(Rn) is dense inW 1,p(x)(Rn). The origin of our work comes from a similar question of Hästö [5] under the density of continuous or Hölder continuous whether it is possible to deduce the density of smooth functions.

Globally stable velocity estimation using normalized velocity measurement

The problem of estimating velocity from a monocular camera and calibrated inertial measurement unit (IMU) measurements is revisited. For the presented setup, it is assumed that normalized velocity measurements are available from the camera. By applying results from nonlinear observer theory, we present velocity estimators with proven global stability under defined conditions, and without the need to observe features from several camera frames. Several nonlinear methods are compared with each other, also against an extended Kalman filter (EKF), where the robustness of the nonlinear methods compared with the EKF are demonstrated in simulations and experiments.
BIOEROSION ON SPINICAUDATA SHELLS FROM A TRIASSIC FRESHWATER PALEOLAKE, MENDOZA, ARGENTINA

Abstract: Bioerosion by microorganisms is termed microbioerosion. In aquatic systems, microbioerosion affects various substrates, most commonly relatively soluble ones such as sulfates, phosphates, and carbonates. However, the record of microbioerosion in fossil calcareous organisms in lake environments is limited. In northern Mendoza Province, at the locality Paramillos de Uspallata, Triassic sedimentary rocks outcrop, including the Agua de la Zorra Formation, which was deposited in a deltaic and lacustrine system. This study assesses possible bioerosion by microorganisms on spinicaudata shells from the lacustrine sequence and discusses their preservation potential in lacustrine environments. Spinicaudatans from the Agua de la Zorra Formation were analyzed under a binocular microscope and via scanning electron microscopy. Traces, the product of microbioerosion, preserved as molds, were assigned as Type 1 and 2 and were then compared with those generated by cyanobacteria, bacteria, chlorophyte, and fungi that inhabit fresh and brackish water environments. Microbioerosion occurs post-mortem and enhances dissolution of the spinicaudata shells. This, together with bias in extraction methodologies and sampling, is considered the reason for the rarity of spinicaudatans with traces of bioerosion in the lacustrine record.
Detection of carbapenemase-producing Pseudomonas aeruginosa by phenotypic and genotypic methods in a tertiary care hospital of East India

Abstract BACKGROUND: Carbapenemase-producing Pseudomonas aeruginosa is a serious threat in hospital infection due to its multidrug resistance. AIM: The aim of the study was to determine the frequency of carbapenem resistance in clinical isolates of Pseudomonas aeruginosa and detect the presence of carbapenemase enzymes in carbapenem-resistant P. aeruginosa (CRPA) isolates by phenotypic and genotypic methods. MATERIAL AND METHODS: Double-disk synergy test [DDST] and combined disk synergy test [CDST]) was performed in CRPA isolates and the prevalence ofblaKPC,blaNDM-1,blaIMP,blaVIM,blaSIM,blaSPM,blaGIM, andblaOXA-48 was determined. RESULTS: Of 559 isolates included in the study, a total of 102 isolates were resistant to carbapenem that accounted for overall 18.24% (102/559) prevalence. Of these 102 isolates, 89 (87.25%) isolates were positive by DDST and 95 (93.17%) isolates were positive by CDST. Of 102 CRPA isolates,blaVIM was detected in 30 isolates (30/102, 29.1%), followed byblaNDM-1 in 29 (29/102, 28.4%) isolates andblaSIM andblaGIM in 6 isolates each (6/102, 5.8%). A combination of two carbapenemase genes was detected in 12 isolates, with six (6/102, 5.88%) CRPA isolates harboring with bothblaVIM andblaNDM-1 genes. Four isolates were found to harbor a combination of three carbapenem-resistant genes. CONCLUSION: A high rate of carbapenemase production was observed in P. aeruginosa. Coproducers of multiple carbapenemases are also a cause of concern. An in-depth understanding of molecular mechanisms of resistance will be helpful in optimizing patient management and hospital infection control.
Bone-enhanced periodontal plastic surgery: A case series

In recent years, esthetics has become apparently a crucial attribute in the periodontal treatment and is paving the way for newer modalities in the management of gingival recession. Gingival recession is one of the pivotal soft tissue problems that often constitute a challenge to a periodontist. The prognostic predictability in the management of gingival recession has been questionable when adequate bone support is not available. This case series propounds a technique that combines periodontal plastic surgery along with bone grafts, to give space for soft tissue coverage and adequate support. Case series brings a novel technique to the limelight, wherein bone substitutes are added to the conventional periodontal plastic surgical procedures, to enhance support for the soft tissue. Case series includes three patients with Millers Class II and Class III recession, involves a technique, which combines xenograft along with any one of the conventional plastic surgical procedures such as coronally advanced flap or pedicle flap. Pre- and post-operatively, clinical and radiographical parameters were evaluated. Satisfactory Clinical outcome was obtained when bone substitute were added to conventional periodontal plastic surgeries for root coverage and hence it prerequisites the need for long term evaluation.
Comparing the efficacy of a combination of artificial lymphatics in the form of silicone tube and compressive therapy versus compressive therapy only in upper limb lymphedema following axillary lymph node dissection in breast cancer patients: A randomized controlled trial

Objectives of this Trial: The objectives of this trial were to compare the treatment of lymphedema by creating artificial pathways along with standard compressive therapy versus standard therapy alone in Stage 2 and 3 lymphedema. Materials and Methods: A total of 18 patients were randomized into two groups. Silicone group (n = 8) received the placement of fenestrated silicone tubes subcutaneously from the hand to scapular region along with standard compression therapy, and the control group (n = 10) received standard compression therapy only. Follow-up was for 6 months. Results: A mean reduction of limb volume in the silicone group was 887 ml (25%), whereas in the control group, it was 250 ml (8%) (P = 0.01). All patients, 8 (100%) of silicone group and only 4 (40%) of control group, had ≥10% limb volume reduction at the end of 24 weeks with P = 0.013. More number of patients in the silicone group had a mean reduction in limb circumference of ≥2 cm as compared to the control group at almost all points of measurements along the limb with P < 0.05. There was a significant improvement in the quality of life, especially the functional domain in the silicone group with a P = 0.01. Improvement in pain-free range of motion in all major joints was observed in both the groups. No serious complications were reported. Postoperative ultrasonography and lymphoscintigraphy have shown patency of tubes, lymphatic fluid flow in silicone tubes. Postoperative indocyanine green lymphography showed decreased dermal backflow compared to preoperative. Conclusion: Combination of artificial lymphatics in the form of silicone tubes and standard care leads to a more significant reduction in the limb volume and limb circumference with improved quality of life with no serious complications.
Inadvertent carotid-jugular conduit: An uncommon yet dreaded jugular venous catheterization complication

Carotid-jugular fistula is one of the uncommon complications of internal jugular vein catheterization. It can have serious consequences such as infection, embolization, and high output cardiac failure and requires invasive repair. We describe a case of a common carotid artery-jugular vein arteriovenous fistula following the insertion of a double-lumen catheter for hemodialysis access.
Effect of high dose vitamin D supplementation in combination with weight loss diet on Glucose homeostasis, insulin resistance and matrix metalloproteinases in obese subjects with vitamin D deficiency: a double blind placebo-controlled randomized clinical trial.

As there is limited and inconsistent evidence in potential role of vitamin D on insulin resistance and matrix metalloproteinases, this study aimed to examine the effect of vitamin D supplementation on glucose homeostasis, insulin resistance and matrix metalloproteinases in obese subjects with vitamin D deficiency. A total of 44 participants with serum 25(OH)D level ≤ 50 nmol/L and body mass index (BMI) 30-40 kg/m2 were randomly allocated into receiving weight reduction diet with either 50000 IU vitamin D3 pearl (n = 22) or placebo (n = 22) once weekly for 12 weeks. Primary outcomes were changes in fasting serum glucose (FSG), homeostasis model assessment insulin resistance (HOMA-IR), quantitative insulin sensitivity check index (QUICKI) and matrix metalloproteinases (MMPs). Secondary outcomes were changes in weight, body mass index (BMI), 25(OH) D, calcium, phosphorous and Parathyroid hormone (PTH). Sun exposure and dietary intakes were also assessed. Serum levels of 25(OH) D3 increased significantly with a simultaneous decrease in serum concentration of PTH in vitamin D group. Weight, BMI, FSG and MMP-9 decreased significantly in both groups; while there were found significant differences in changes in weight, serum 25(OH) D3, PTH and MMP-9 levels between the groups. Within and between groups analysis revealed no significant differences in serum calcium, phosphorous, serum insulin, HOMA-IR, QUICKI and MMP-2 after intervention. Our results indicated that improvement in vitamin D status resulted in greater reductions in weight and MMP-9 during weight loss. These preliminary results are sufficient to warrant a bigger study group.
Structure and Mechanism of P-Type ATPase Ion Pumps.

P-type ATPases are found in all kingdoms of life and constitute a wide range of cation transporters, primarily for H+, Na+, K+, Ca2+, and transition metal ions such as Cu(I), Zn(II), and Cd(II). They have been studied through a wide range of techniques, and research has gained very significant insight on their transport mechanism and regulation. Here, we review the structure, function, and dynamics of P2-ATPases including Ca2+-ATPases and Na,K-ATPase. We highlight mechanisms of functional transitions that are associated with ion exchange on either side of the membrane and how the functional cycle is regulated by interaction partners, autoregulatory domains, and off-cycle states. Finally, we discuss future perspectives based on emerging techniques and insights. Expected final online publication date for the Annual Review of Biochemistry, Volume 89 is June 22, 2020.

Noninvasive Physiological Screening for Mild Traumatic Brain Injury: Preliminary Findings of a Case Series

A preliminary case series demonstrates how the use of fine-motor-control measurements of the hands may be used for screening for mild traumatic brain injury (mTBI) symptoms. Motor and sensory control factors have been derived from rapid fine-motor-control measurements collected at 4-millisecond intervals during a total of two 1-minute periods for each hand in a repetitious squeeze-and-relax cycle. These derived control factors detect the presence of mTBI symptoms and can measure and document the rate of recovery for persons with mTBI. This information is critically important to determine the efficacy of a therapeutic or rehabilitative regimen as well as to assign the optimal time to return to work or play.
The resistome and genomic reconnaissance in the age of malaria elimination

ABSTRACT Malaria is an infectious disease caused by parasitic protozoa in the Plasmodium genus. A complete understanding of the biology of these parasites is challenging in view of their need to switch between the vertebrate and insect hosts. The parasites are also capable of becoming highly motile and of remaining dormant for decades, depending on the stage of their life cycle. Malaria elimination efforts have been implemented in several endemic countries, but the parasites have proven to be resilient. One of the major obstacles for malaria elimination is the development of antimalarial drug resistance. Ineffective treatment regimens will fail to remove the circulating parasites and to prevent the local transmission of the disease. Genomic epidemiology of malaria parasites has become a powerful tool to track emerging drug-resistant parasite populations almost in real time. Population-scale genomic data are instrumental in tracking the hidden pockets of Plasmodium in nationwide elimination efforts. However, genomic surveillance data can be useful in determining the threat only when combined with a thorough understanding of the malarial resistome – the genetic repertoires responsible for causing and potentiating drug resistance evolution. Even though long-term selection has been a standard method for drug target identification in laboratories, its implementation in large-scale exploration of the druggable space in Plasmodium falciparum, along with genome-editing technologies, have enabled mapping of the genetic repertoires that drive drug resistance. This Review presents examples of practical use and describes the latest technology to show the power of real-time genomic epidemiology in achieving malaria elimination. Summary: This Review discusses the challenges in malaria elimination and how implementation of national-scale genomic surveillance programmes in combination with resistome analyses could provide a powerful solution.
Journey to multimorbidity: longitudinal analysis exploring cardiovascular risk factors and sociodemographic determinants in an urban setting

Objective To study the social determinants and cardiovascular risk factors for multimorbidity and the acquisition sequence of multimorbidity. Design Longitudinal study based on anonymised primary care data. Setting General practices in an urban multiethnic borough in London, UK. Participants 332 353 patients aged ≥18 years. Main outcome measures Clinical and sociodemographic characteristics of patients with multimorbidity, defined as ≥3 of 12 long-term conditions (LTCs) selected according to high predicted healthcare use. Multilevel logistic regression was used to model social determinants and cardiovascular risk factors. Alluvial plots were constructed to illustrate multimorbidity acquisition sequences according to age, ethnicity and social deprivation. Results 5597 (1.7%) patients had ≥3 selected LTCs, the ‘multimorbidity cohort’. The the most common LTCs were diabetes (63.0%) and chronic pain (CP) (42.8%). Social deprivation and ethnicity were independent determinants of multimorbidity: most compared with the least deprived quintile (adjusted OR (AOR) 1.56 (95% CI 1.41 to 1.72)); South Asian compared with white ethnicity (AOR 1.44 (95% CI 1.29 to 1.61)); and black compared with white ethnicity (AOR 0.86 (95% CI 0.80 to 0.92)). The included cardiovascular risk factors were relatively strong determinants of multimorbidity: hypertension (AOR 5.05 (95% CI 4.69 to 5.44)), moderate obesity (AOR 3.41 (95% CI 3.21 to 3.63)) and smoking (AOR 2.30 (95% CI 2.16 to 2.45)). The most common initial onset conditions were diabetes and depression; diabetes particularly in older and black ethnic groups; and depression particularly in younger, more deprived and white ethnicity groups. CP was less common as an initial condition. Conclusion Our findings confirm the importance of age, social deprivation and ethnicity as determinants of multimorbidity. Smoking, obesity and hypertension as cardiovascular risk factors were stronger determinants of multimorbidity than deprivation or ethnicity. The acquisition sequence of multimorbidity is patterned by sociodemographic determinants. Understanding onset conditions of multimorbidity and cardiovascular cardiovascular risk factors may lead to the development of interventions to slow the progression of multimorbidity.
An endocannabinoid-regulated basolateral amygdala-nucleus accumbens circuit modulates sociability.

Deficits in social interaction (SI) are a core symptom of Autism Spectrum Disorders (ASD), however treatments for social deficits are notably lacking. Elucidating brain circuits and neuromodulatory signaling systems that regulate sociability could facilitate a deeper understanding of ASD pathophysiology and reveal novel treatments for ASD. Here we found that in vivo optogenetic activation of the basolateral amygdala-nucleus accumbens (BLA-NAc) glutamatergic circuit reduced SI and increased social avoidance in mice. Furthermore, we found that 2-arachidonoylglycerol (2-AG) endocannabinoid (eCB) signaling reduced BLA-NAc glutamatergic activity, and that pharmacological 2-AG augmentation via administration of JZL184 blocked SI deficits associated with in vivo BLA-NAc stimulation. Additionally, optogenetic inhibition of the BLA-NAc circuit significantly increased SI in the Shank3B-/-, an ASD model with substantial SI impairment, without affecting SI in wild-type mice. Finally, we demonstrated that JZL184 delivered systemically or directly to the NAc also normalized SI deficits in Shank3B-/-mice, while ex vivo JZL184 application corrected aberrant NAc excitatory and inhibitory neurotransmission and reduced BLA-NAc-elicited feedforward inhibition of NAc neurons in Shank3B-/- mice. These data reveal circuit-level and neuromodulatory mechanisms regulating social function relevant to ASD and suggest 2-AG augmentation could reduce social deficits via modulation of excitatory and inhibitory neurotransmission in the NAc.
