Gravitational wave, collider and dark matter signals from a scalar singlet electroweak baryogenesis

We analyse a simple extension of the SM with just an additional scalar singlet coupled to the Higgs boson. We discuss the possible probes for electroweak baryogenesis in this model including collider searches, gravitational wave and direct dark matter detection signals. We show that a large portion of the model parameter space exists where the observation of gravitational waves would allow detection while the indirect collider searches would not.Ankit Beniwal, Marek Lewicki, James D.

Periodic Peritoneal Dialysis in End Stage Renal Disease: Is it Still Relevant? A Single Center Study from India

Background: High cost of maintenance hemodialysis (HD) and continuous ambulatory peritoneal dialysis (PD) in India has made renal replacement therapy out of reach of many patients with end stage renal disease (ESRD). Repeated puncture PD although inferior to HD biochemically, is easily and freely available across Rajasthan, India, and is simple to perform, and does not require sophisticated machines, thus making it an attractive option for dialysis for ESRD. Aim: To analyze the outcomes of periodic PD in patients with ESRD requiring dialysis support. Subjects and Methods: A prospective study analyzing the data of patients who underwent PD between August 2010 and January 2013 in Sawai Man Singh Hospital, Jaipur, India was conducted. Patients were divided into three groups based on the time period between first and second session of PD. Detailed demographic and clinical data during the study period were collected along with PD related complications. The main outcome studied was technique survival 1 year post initiation of PD. Results: 234 patients received an initial session of PD, of which 174 had a good response and were included in the study. 19 patients received the second PD within 7 days of first (Group 1), 45 patients within 8–14 days (Group 2) and 110 patients within 15–21 days (Group 3). The overall 1 year technique survival was 68.4% (91/133), with a rate of 50% (5/10), 56.8% (21/37), and 75.6% (65/86) for Group 1, Group 2, and Group 3, respectively. The time duration between first and second PD proved to be reliable indicator of the subsequent response, with a technique survival rate significantly lower in Group 1 patients compared to Groups 2 and 3 (P = 0.04). Median dialysis free days were 11, 16 and 21 days in Group 1, Group 2, and Group 3, respectively. Peritonitis rate observed was 2.1% (49/2261) during the study period. Conclusion: Periodic PD is a simple, safe and cheap procedure, which can be considered as used as a palliative measure in terminal uremia in underprivileged areas.Keywords: Peritoneal dialysis, End stage renal disease, Renal replacement therap

Eco-friendly textile-based wearable humidity sensor with multinode wireless connectivity for healthcare applications

Textile-based wearable humidity sensors are of great interest for human healthcare monitoring as they can provide critical human-physiology information. The demand for wearable and sustainable sensing technology has significantly promoted the development of eco-friendly sensing solutions for potential real-world applications. Herein, a biodegradable cotton (textile)-based wearable humidity sensor has been developed using fabsil-treated cotton fabric coated with a poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) sensing layer. The structural, chemical composition, hygroscopicity, and morphological properties are examined using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), contact angle measurement, and scanning electron microscopy (SEM) analysis. The developed sensor exhibited a nearly linear response (Adj. R-square value observed as 0.95035) over a broad relative humidity (RH) range from 25 to 91.5%RH displaying high sensitivity (26.1%/%RH). The sensor shows excellent reproducibility (on replica sensors with a margin of error ±1.98%) and appreciable stability/aging with time (>4.5 months), high flexibility (studied at bending angles 30°, 70°, 120°, and 150°), substantial response/recovery durations (suitable for multiple applications), and highly repeatable (multicyclic analysis) sensing performance. The prospective relevance of the developed humidity sensor toward healthcare applications is demonstrated via breathing rate monitoring (via a sensor attached to a face mask), distinguishing different breathing patterns (normal, deep, and fast), skin moisture monitoring, and neonatal care (diaper wetting). The multinode wireless connectivity is demonstrated using a Raspberry Pi Pico-based system for demonstrating the potential applicability of the developed sensor as a real-time humidity monitoring system for the healthcare sector. Further, the biodegradability analysis of the used textile is evaluated using the soil burial degradation test. The work suggests the potential applicability of the developed flexible and eco-friendly humidity sensor in wearable healthcare devices and other humidity sensing applications

Reduction in seed cotton yield corresponding with symptom severity grades of cotton leaf curl disease (CLCuD) in upland cotton (Gossypium hirsutum L.)

Not AvailableCotton leaf curl disease is the major constraint in cotton production in the Indian subcontinent. A field study (2012-2017) was conducted to assess seed cotton yield on Bt cotton cultivars analogous to the symptom rating scales (DRS) of CLCuD. The DRS is used to derive the percent disease intensity (PDI). Presently, percent disease index (PDI) for resistance screening ranges between 0.1 to 50%, corresponding to the DRS 1 to 6, which is lower than the mathematical midpoint value ranging between 8.4 to 91.8% and breeding material with good yield potential may be ignored during screening. The average yield loss corresponding to the DRS 1, 2, 3, 4, 5, and 6 was 15, 28, 38.6, 49.1, 59.1 and 72.1%. Hence, the newly proposed disease response scale would be much more justifiable and reliable for decision-making and determining the level of resistance or susceptibility in the genotypes, because the estimated severity may be much lower than the actual severityNot Availabl

The ScotoSinglet Model: a scalar singlet extension of the Scotogenic Model

The Scotogenic Model is one of the most minimal models to account for both neutrino masses and dark matter (DM). In this model, neutrino masses are generated at the one-loop level, and in principle, both the lightest fermion singlet and the lightest neutral component of the scalar doublet can be viable DM candidates. However, the correct DM relic abundance can only be obtained in somewhat small regions of the parameter space, as there are strong constraints stemming from lepton flavour violation, neutrino masses, electroweak precision tests and direct detection. For the case of scalar DM, a sufficiently large lepton-number-violating coupling is required, whereas for fermionic DM, coannihilations are typically necessary. In this work, we study how the new scalar singlet modifies the phenomenology of the Scotogenic Model, particularly in the case of scalar DM. We find that the new singlet modifies both the phenomenology of neutrino masses and scalar DM, and opens up a large portion of the parameter space of the original model.Ankit Beniwal, Juan Herrero-García, Nicholas Leerdam, Martin White and Anthony G.

Role Of An Eriophyid Mite Aceria Cajani (Acari: Eriophyidae) In Transmission And Spread Of Sterility Mosaic Of Pigeonpea

Sterility mosaic (SM) is one of the most important diseases of pigeonpea (Cajanus cajan (L.) Millsp.) in India causing an annual loss of 205,000 tonnes of grain, especially in the states of Bihar, Gujarat, Karnataka and Uttar Pradesh (Kannaiyan el ai, 1984). The disease is presumed to be caused by a virus, although the causal agent is yet to be determined (Capoor, 1952). Selh (1962) and Nene (1972) reported that the eriophyid mite, Acer/a cajant ChannaBasavanna could transmit SM. However, in spite of the lack of evidence of the viral nature of this pathogen and its association with the diseased plants, mite toxaemia could be the possible cause of SM (Slykhuis, 1980). There is also no information on the nature and extent of spread of the disease under field conditions and the relationship between the mite vector and SM pathogen. In this paper, results of the studies on the possibility of a mite-transmitted pathogen being the cause of SM, relationship between the mile vector and SM pathogen, and spread of the disease and the mite vector under field conditions are reported
