Modular Acquisition and Stimulation System for Timestamp-Driven Neuroscience Experiments

Dedicated systems are fundamental for neuroscience experimental protocols that require timing determinism and synchronous stimuli generation. We developed a data acquisition and stimuli generator system for neuroscience research, optimized for recording timestamps from up to 6 spiking neurons and entirely specified in a high-level Hardware Description Language (HDL). Despite the logic complexity penalty of synthesizing from such a language, it was possible to implement our design in a low-cost small reconfigurable device. Under a modular framework, we explored two different memory arbitration schemes for our system, evaluating both their logic element usage and resilience to input activity bursts. One of them was designed with a decoupled and latency insensitive approach, allowing for easier code reuse, while the other adopted a centralized scheme, constructed specifically for our application. The usage of a high-level HDL allowed straightforward and stepwise code modifications to transform one architecture into the other. The achieved modularity is very useful for rapidly prototyping novel electronic instrumentation systems tailored to scientific research.Comment: Preprint submitted to ARC 2015.

‘Doctrine Of Doli Incapax’ (Crime Committed By Minor And Their Rehabilitation)

In the present scenario, crime is increasing day by day in our society and it’s affected the upcoming generation and also affected the ideology of youth and especially of children aged between 7 to 16 years old. Further the term ‘doli incapx’ it’s a Latin language word also an obscure doctrine of ancient origin that provides a presumption that children over the age of criminal responsibility but under a certain age are incapable to commit a crime or offense, even an age category is defined under Indian penal Code in which a child up to the limit of age is incapable to commit any crime if done so then he will be exempted from the penalty for that crime committed by him and our Indian Penal law also further define a category of children which can commit a crime or has knowledge of criminal activity or having the capability to commit a crime that also known as ‘doli capax’ and there is also special category and procedure to tried that children under special law and they also kept under separate facility or observation during the trial and after the conviction. I think it is hard to regard this ancient rule about the capacity of a child between ten and fourteen as altogether satisfactory or suited to modern conditions. Nevertheless, it is clearly the law and we have to enforce it. ‘No civilized society’, says Professor Colin Howard in his book entitled Criminal Law, 4th ed. (1982), p 343, ‘regards children as accountable for their actions to the same extent as adults’.’... The wisdom of protecting young children against the full rigor of criminal law is beyond argument. The difficulty lies in determining when and under what circumstances that protection should be removed. &nbsp

Radiative Transfer for Exoplanet Atmospheres

Remote sensing of the atmospheres of distant worlds motivates a firm understanding of radiative transfer. In this review, we provide a pedagogical cookbook that describes the principal ingredients needed to perform a radiative transfer calculation and predict the spectrum of an exoplanet atmosphere, including solving the radiative transfer equation, calculating opacities (and chemistry), iterating for radiative equilibrium (or not), and adapting the output of the calculations to the astronomical observations. A review of the state of the art is performed, focusing on selected milestone papers. Outstanding issues, including the need to understand aerosols or clouds and elucidating the assumptions and caveats behind inversion methods, are discussed. A checklist is provided to assist referees/reviewers in their scrutiny of works involving radiative transfer. A table summarizing the methodology employed by past studies is provided.Comment: 7 pages, no figures, 1 table. Filled in missing information in references, main text unchange

Comparative Analgesic and Anti-inflammatory Activities of Two Polyherbal Tablet Formulations (Aujaie and Surangeen) in Rats

Purpose: To investigate the analgesic and anti-inflammatory activities of two herbal polymedicines - Aujaie and Surangeen to ascertain their therapeutic claims.Methods: A total of 96 rats were divided into two equal groups; one for determination of antiinflammatory activity and the other for analgesic activity. Anti-inflammatory and analgesic activities were evaluated by carrageenan-induced paw edema and formalin-induced paw licking test, respectively. For both studies, group I (untreated control) received 1 ml/kg, (po) of gum suspension 1 h before carrageenan injection. Aspirin (100 mg/kg, po) was given to group II (treated control) before injection. Groups III, IV and V were administered orally aujaie (3, 4 and 5 mg/kg, po, respectively), while surangeen tablets (10, 20 and 40 mg/kg, po) were given to groups VI, VII and VIII, respectively. Pain was experimentally induced by injecting 0.1 ml of 2.5 % formalin (40 % formaldehyde in distilled water) via the subplantar region of the left hind paw.Results: Significant (p < 0.05) anti-inflammatory activity for aspirin (group II as well as for groups III - VIII with paw edema inhibition (PDI) ranging from 24.6 - 90.2 %, There was significant ((p < 0.05) analgesic activity in group II, VI and VII while in groups III - V and VIII the activity was insignificant (p < 0.05).Conclusion: Aujaie and surangeen tablets exhibited pronounced analgesic and anti-inflammatory activities in rats depending on the dose employed.Keywords: Aujaie, Surangeen, Anti-inflammatory, Analgesic

Volumetric laser endomicroscopy and its application to Barrett's esophagus: results from a 1,000 patient registry.

Volumetric laser endomicroscopy (VLE) uses optical coherence tomography (OCT) for real-time, microscopic cross-sectional imaging. A US-based multi-center registry was constructed to prospectively collect data on patients undergoing upper endoscopy during which a VLE scan was performed. The objective of this registry was to determine usage patterns of VLE in clinical practice and to estimate quantitative and qualitative performance metrics as they are applied to Barrett's esophagus (BE) management. All procedures utilized the NvisionVLE Imaging System (NinePoint Medical, Bedford, MA) which was used by investigators to identify the tissue types present, along with focal areas of concern. Following the VLE procedure, investigators were asked to answer six key questions regarding how VLE impacted each case. Statistical analyses including neoplasia diagnostic yield improvement using VLE was performed. One thousand patients were enrolled across 18 US trial sites from August 2014 through April 2016. In patients with previously diagnosed or suspected BE (894/1000), investigators used VLE and identified areas of concern not seen on white light endoscopy (WLE) in 59% of the procedures. VLE imaging also guided tissue acquisition and treatment in 71% and 54% of procedures, respectively. VLE as an adjunct modality improved the neoplasia diagnostic yield by 55% beyond the standard of care practice. In patients with no prior history of therapy, and without visual findings from other technologies, VLE-guided tissue acquisition increased neoplasia detection over random biopsies by 700%. Registry investigators reported that VLE improved the BE management process when used as an adjunct tissue acquisition and treatment guidance tool. The ability of VLE to image large segments of the esophagus with microscopic cross-sectional detail may provide additional benefits including higher yield biopsies and more efficient tissue acquisition.

Assess the effectiveness of structured teaching program regarding Human Milk Banking in terms of knowledge among BSc nursing students

Background: Breastfeeding is the most effective way to feed infants since it is particularly tailored to the infant's needs. In Vienna, Austria, the first human milk bank was created in 1909. In 1989, Lokmanya Tilak Municipal Hospital established Asia's inaugural human milk bank. The "National guidelines on Lactation Management Centres in Public Health facilities" which were published in 2017, include guidelines for setting up Comprehensive Lactation Management Centres (CLMCs) for the purpose of collecting, storing, processing, and dispensing donor human milk for infants admitted to public health facilities as well as offering lactation support to mothers at all delivery points. Nursing students play a crucial role in addressing the complex needs of individuals with structured teaching program on human milk banking.\Methodology: A quasi- experimental one group pretest posttest design was employed for the sample was selected using a convenience sampling technique. The intervention consisted of structured teaching program on human milk banking. The analysis of the data was conducted using both descriptive and inferential statistics with SPSS version 20.Result: The study included 80 BSc Nursing students. Pre-intervention knowledge scores ranged from 3 to 19, with a mean score of 11.5 ± 3.2. Following the structured teaching program, post-test scores ranged from 9 to 20, with a significantly higher mean of 16.7 ± 2.4. The mean difference of -5.1 was statistically significant (t = -11, p < 0.01), indicating substantial improvement in knowledge. Among demographic variables, only religion showed a statistically significant association with pre-test knowledge levels (p = 0.01); other variables such as age, gender, and prior exposure to human milk banking showed no significant influence.Conclusion: Structured teaching program was effective in enhancing the competency knowledge on human milk banking of nursing students. As the study findings showed that the mean posttest scores of nursing students were higher rather than pre test.Recommendations: A similar study can be conducted with large sample size in different settings should be conducted to determine the effect of structured teaching program on human milk banking on students competency

Implantable Doppler Probe as a Vascular Monitoring Device in Kidney Transplant Patients: Investigation of Use at a Single Center.

OBJECTIVES: Vascular complications account for 30% to 35% of total kidney grafts lost during the first 3 months posttransplant. Early detection of vascular complications allows an opportunity for prompt intervention, which is critical to reducing graft loss. In this study, we evaluated the usefulness of an implantable Doppler probe as a vascular monitoring device in kidney transplant patients. MATERIALS AND METHODS: An implantable Doppler probe is used intermittently for postoperative monitoring of kidney transplant patients at our center. In this retrospective study, we analyzed prospectively maintained medical data in which we compared clinical outcomes of kidney transplant recipients who had postoperative implantable Doppler probe monitoring versus standard care clinical observation. Between January 2016 and October 2021, 324 kidney transplant patients were seen at our center. Patients were divided into 2 groups: group 1 (n = 194; 60%) included kidney transplant recipients with postoperative implantable Doppler probe monitoring and group 2 (n = 129; 40%) included kidney transplant recipients with standard care clinical observation. We compared number of vascular complications, number of departmental ultrasonographic scans required posttransplant, and graftloss at 3 months between the 2 groups. RESULTS: Vascular complications were identified in 13.5% of total patients, with graft loss identified in 2.1%. Both groups were similar in demographical characteristics. Group 1 had more vascular complications (17.5% vs 9.3%; relative risk = 1.88), fewer ultrasonographic scans during the first 24 hours posttransplant (71.1% vs 83.7%; relative risk = 0.84), and lower graft loss (1.5% vs 3.1%; relative risk = 0.48) than group 2. All probes were removed safely after 72 hours, and no complications related to the device were reported. CONCLUSIONS: The monitoring device may be used as an additional adjunct for graft monitoring in kidney transplant patients. Further controlled studies are warranted to evaluate this device in clinical practice

Measurement of CP-violation asymmetries in D0 to Ks pi+ pi-

We report a measurement of time-integrated CP-violation asymmetries in the resonant substructure of the three-body decay D0 to Ks pi+ pi- using CDF II data corresponding to 6.0 invfb of integrated luminosity from Tevatron ppbar collisions at sqrt(s) = 1.96 TeV. The charm mesons used in this analysis come from D*+(2010) to D0 pi+ and D*-(2010) to D0bar pi-, where the production flavor of the charm meson is determined by the charge of the accompanying pion. We apply a Dalitz-amplitude analysis for the description of the dynamic decay structure and use two complementary approaches, namely a full Dalitz-plot fit employing the isobar model for the contributing resonances and a model-independent bin-by-bin comparison of the D0 and D0bar Dalitz plots. We find no CP-violation effects and measure an asymmetry of ACP = (-0.05 +- 0.57 (stat) +- 0.54 (syst))% for the overall integrated CP-violation asymmetry, consistent with the standard model prediction.Comment: 15 page
