Clinico-radiological correlation between serum calcium and acute ischemic stroke

Background: Ischemic injury in stroke leads to intracellular calcium accumulation, which activates the enzyme cascade causing cell death. Aims: To determine the correlation between serum calcium (Ca) and albumin-corrected calcium (CCa) levels with acute ischemic stroke (AIS) for short-term outcome and infarct size (IS). Methods: An observational study was carried out in 50 patients in a tertiary care hospital in India over 2 years (from December 2008 to December 2010). Patients presenting within 72 h of stroke onset and aged ≥40 years were included. Ca was measured, CCa calculated, and head computed tomography (CT) scan was done. National Institute of Health Stroke Scale (NIHSS) was calculated on admission and after 1 week, and Barthel Index (BI) was calculated at 1 week. Pearson′s correlation coefficient was calculated between NIHSS, BI, and IS with both, Ca and CCa. Also, subgroup analysis was done in lacunar, lobar, anterior circulation, posterior circulation, unilateral, and bilateral stroke subgroups. Results: Ca had a significant correlation with NIHSS, BI, and IS (all patients), with BI in lacunar and unilateral strokes and both NIHSS (admission) and BI in lobar, anterior circulation, and bilateral strokes. CCa had a significant correlation with IS and with BI in all patients and in anterior circulation strokes. NIHSS (admission) and BI had a significant correlation with IS. Conclusions: Higher Ca (CCa in some subgroups) is associated with better prognosis and recovery after AIS (except in posterior circulation strokes), and higher Ca and CCa are both associated with smaller IS.
Enhancing periocular recognition using Bayesian support vector machine attractive for recognition

Periocular recognition has been an active research area in the field of biometrics. The periocular region is normally a rectangular region localized by the eye center or the inner and outer corners of the eye. Choosing features that represent the reliable and discriminative properties of the periocular region is one of the most critical tasks in the periocular recognition problem. This project tackles this feature extraction problem and proposes a novel approach to efficiently extract discriminative properties of the periocular region with high recognition performance. The proficiency to learn robust features from the images makes the Bayesian support vector machine (BSVM) attractive for recognition. Harlick features and edge histogram descriptor is used to extract the features of training images.
Development of FEM-based simulation methods for facilitating the design process of electromagnetic vibration energy harvesters

Electromagnetic vibration energy harvesting is an emerging technology for extracting small amounts of electrical energy from vibrations. It can be used to power sensors and data transmission equipment for monitoring industrial processes and machines in hard-to-access-places without easy access to electricity, without requiring regular replacement like batteries. Methods, models and software to aid the design process of springs for electromagnetic vibration energy harvesters have been developed in this work. It has been carried out at ReVibe Energy, a company which develops such harvesters. Previous FEM simulations of eigenfrequencies in the harvesters showed poor correspondence with experiments. To investigate this, experiments to measure stiffnesses of springs were set up. This was done by suspending weights in the springs. It was found that also the stiffness of the springs corresponded poorly to finite element simulations. There were also significant differences between spring individuals that were nominally identical. Dimensional measurements were conducted on the springs, and it was found that the spring arms were generally narrower than specified in drawings for the components. There were also arm width variations between individuals, which correspond to and explain the between-individuals stiffness variations. When simulations were performed with corrections for arm width, the stiffness prediction error was reduced by approximately 50 %. The methodology employed in designing and manufacturing springs was studied, in an effort to improve spring design while making the design work less cumbersome. With the purpose of removing manual iterative design loops, which are very time-consuming, a method for automatically generating and evaluating different spring designs was conceived. It consists of automatic changes to a CAD-file in Autodesk Inventor, export of a STEP file containing the component geometry, meshing of the component with GMSH, finite element analysis on the mesh using Elmer, and finally evaluation of results. This was implemented in a software program written in Python.
Antecedents and Consequents of Brand Love in the Smartphone Market: An Extended Study of the Impact of Switching Cost

Abstract Smartphones, whose product lifespan is relatively short, still call for a better understanding of the role played by the brands when it comes to the customer’s buying decision. The objective of the present investigation is to test, in terms of validity, an extension of the Brand Love Model by Caroll and Ahuvia (2006); more specifically for the smartphone category, with the inclusion of the constructs Brand Switching Cost and Operational System Switching costs. In this direction, a survey was carried out and 453 users of smartphones responded. The analysis or the result was done by means of structural equation modeling and the results indicated that most of the relations predicted in the model proposed were confirmed, with an emphasis placed on significant influences of Brand Switching Cost on Loyalty. Other findings and their theoretical and general contributions of the investigation were discussed.
Classical logic and the division by zero

The division by zero turned out to be a long lasting and not ending puzzle in mathematics and physics. An end of this long discussion appears not to be in sight. In particular zero divided by zero is treated as indeterminate thus that a result cannot be found out. It is the purpose of this publication to solve the problem of the division of zero by zero while relying on the general validity of classical logic. A systematic re-analysis of classical logic and the division of zero by zero has been undertaken. The theorems of this publication are grounded on classical logic and Boolean algebra. There is some evidence that the problem of zero divided by zero can be solved by today’s mathematical tools. According to classical logic, zero divided by zero is equal to one.
Split face comparative study for efficacy of microneedling alone versus microneedling combined with vitamin c in treating facial acne scars

Background: Microneedling a newer treatment modality for facial acne scars induces collagen production through mechanical stimulation of the dermis and leads to the softening of scars, realignment of collagen bundles and stimulation of new collagen. Topical vitamin C have beneficial effect on acne and improves acne scarring when used in conjunction with glycolic acid peels and post-laser resurfacing. Aims: Split face comparative assessment of the efficacy of microneedling therapy versus microneedling therapy in conjunction with topical vitamin C in facial acne scars. Materials and Methods: This study was performed on 50 patients having facial acne scars after taking informed written consent. The face was divided into right and left half from midline. On the half of face only microneedling and on other side of face microneedling therapy with topical vitamin C (5% L-ascorbic acid) has been used. A total of three session at 4 weeks interval was done in each patient. Facial scars was assessed clinically to grade the severity of scarring, as per the ECCA grading system. Results: Gradual improvement in global score & acne scar types after each sitting of Microneedling as well as Microneedling + Topical Vitamin-C observed. Overall mean percentage improvement with Microneedling + Topical Vitamin-C was more than the mean percentage improvement with Microneedling alone. Conclusion: Microneedling shows significant clinical improvement in the M type scars (rolling), and U type scars (boxcar) and modest improvement in V type scars (ice-pick). Effect of microneedling is enhanced by combining the procedure with application of topical vitamin C.
Crowding and Tail Risk in Momentum Returns

Abstract Several theoretical studies suggest that coordination problems can cause arbitrageur crowding to push asset prices beyond fundamental value as investors feedback trade on each others’ demands. Using this logic, we develop a crowding model for momentum returns that predicts tail risk when arbitrageurs ignore feedback effects. However, crowding does not generate tail risk when arbitrageurs rationally condition on feedback. Consistent with rational demands, our empirical analysis generally finds a negative relation between crowding proxies constructed from institutional holdings and expected crash risk. Thus our analysis casts both theoretical and empirical doubt on crowding as a stand-alone source of tail risk.
The policy transfer of community-based rehabilitation in Gulu, Uganda

Abstract This paper explores the influence of the community-based rehabilitation approach among international development actors in Gulu, Uganda through the lens of policy transfer. Developed by international organizations, this approach has been promoted as a meaningful way to address the needs of persons with disabilities in low-income countries. This qualitative case study consists of a questionnaire completed by representatives from 25 different organizations, in addition to semi-structured follow-up interviews with 8 development professionals. The findings indicate that the community-based rehabilitation approach has had some influence, as respondents appeared cognisant of key principles of the approach in relation to persons with disabilities. However, detailed knowledge of the approach is mainly limited to the field of health, and there were few current examples of the approach being implemented. These results illustrate the challenges of implementing community-based rehabilitation specifically, as well as broader issues related to the transfer of international policy ideas to the Global South. Points of interest Community-based rehabilitation is a way of helping people with disabilities in low-income countries where services are limited Development organizations in Gulu, Uganda (like the local government and non-governmental organizations) think that this approach is a good way to support people with disabilities Only a few of the people interviewed for this study had a strong understanding of the community-based rehabilitation approach, and these people mostly worked in the health sector There were no examples of community-based rehabilitation programs in Gulu at the time of the study, but some projects (mostly in the health field) used some ideas drawn from the approach Local development organizations find it difficult to apply policy ideas like community-based rehabilitation, especially when they do not have consistent funding
Exploration of the effects of a rehabilitation programme aiming to improve the activities and participation of people with acquired brain injury : application on kitchen activity

Background: Cognitive and behavioural difficulties following acquired brain injury (ABI) may lead to severe limitations in activities and restrictions in participation. A specific ABI, holistic and multidisciplinary rehabilitation program was developed at the Salpetriere hospital (Paris, France). Over a 7-week period, the program aims to improve participants’ participation by combining individual rehabilitation and environmental scenarios such as meal preparation, transportation etc. Program effects have never been investigated. Objectives: 1) to define and validate the rehabilitation program by a multidisciplinary team using a logic model and 2) to document the program's effect on the activity "prepare meals. " Method: Repeated measurements pre-program (T1 and T2) and post-program (T3, T4, T5 up to 6 months) with 7 subjects using the Cooking Task (CT) (Chevignard, 2000), Instrumental Activities of Daily Living (IADL) (Bottari, 2009), and Measure of Life Habits (LIFE-H) (Noreau, 2002). Results: Using the two standard deviation band method and “non-overlap of all pairs” (NAP) methods for small n design, significant differences in pre and post program measures were found for the total number of errors in CT (6/7 subjects), the need of assistance (IADL). The results of the LIFE-H suggest an effect of improving the preparation of meals for 4/7 subjects. Discussion: The combined results from the CT (fewer errors), IADL and LIFE-H suggest an overall improvement in the activity "preparing a meal" after the rehabilitation program.
Segmented Thrust Faulting: Example From the Northeastern Margin of the Tibetan Plateau

Seismogenic faults are commonly composed of a series of segments, revealed by geometric barriers and along‐strike gradients in fault activity. At the northeastern margin of the Tibetan Plateau, the Minle‐Damaying Fault (MDF), bounding a portion of the eastern Qilian Shan, illustrates segmented paleoseismic behavior of a major seismogenic reverse fault. Field surveys, trench excavations, and drone‐surveyed topography along the MDF reveal scarps with diverse cumulative displacements. Multiple events, with timing constrained by radiocarbon dating, are identified by both trench exposures and analysis of deformed landforms. Both individual coseismic displacements and slip rates taper toward the ends, revealing repeated rupture of the western MDF segment. Not all events present at the center of this segment appear at sites closer to the fault tips, suggesting that some earthquakes did not everywhere rupture to the surface. Isolated rupture of the western segment would produce a Mw7.0 earthquake. However, we cannot rule out correlation of some paleo‐earthquakes between two segments, corresponding to larger events. A cluster of two 7‐m slip events occurred on the eastern segment in the past 1,000 years, one of which may correspond to a multisegment event.

Serum Occludin as a Biomarker to Predict the Severity of Acute Ischemic Stroke, Hemorrhagic Transformation, and Patient Prognosis

Blood-brain barrier (BBB) damage plays an important role in overall brain injury following acute ischemic stroke (AIS). We investigated the potential utility of serum occludin, a BBB damage biomarker, in predicting the severity of AIS, hemorrhagic transformation (HT) and patient prognosis. A total of 243 patients, suspected of suffering an AIS and admitted to the emergency room at Xuanwu Hospital between November 2018 to March 2019, were enrolled in this study. Serum occludin levels were measured by enzyme linked immunosorbent assay and clinical data were collected from each patient. Receiver operating characteristic curves (ROC) were used to analyze the relationship between serum occludin and AIS. Multiple logistic regression analysis was used to analyze the relationship between serum occludin and stroke prognosis. Serum occludin levels were significantly elevated in acute stroke cases compared with those with stroke-like symptoms (P<0.001). In the moderate and severe cerebral infarction (CI) groups, serum occludin levels were significantly higher than those in the mild CI group (P<0.001). Patients with HT had higher occludin levels than non-HT patients (P<0.05). In addition, serum occludin level of patients with poor prognosis was significantly higher than that of the patients with good prognosis for non-reperfusion therapy. The ROC curve showed that serum occludin could reasonably predict HT and poor prognosis. Moreover, serum occludin were independently associated with 90-day poor prognosis. These findings suggest that the serum occludin levels could be used to identify early acute stroke cases and may predict the severity of AIS and HT as well as the prognosis at 90 days.
CCN characteristics during the Indian Summer Monsoon over a rain-shadow region

Abstract. Continuous aerosol and Cloud Condensation Nuclei (CCN) measurements carried out at the ground observational facility situated in the rain-shadow region of the Indian sub-continent are illustrated. These observations were part of the Cloud-Aerosol Interaction Precipitation Enhancement EXperiment (CAIPEEX) during the Indian Summer Monsoon season (June to September) of 2018. Observations are classified as dry-continental (monsoon break) and wet-marine (monsoon active) according to air mass history. CCN concentrations measured for a range of supersaturations (0.2–1.2 %) are parameterized using Twomey's empirical relationship. CCN concentrations even at low (0.2 %) supersaturation (SS) were high (> 1,000 cm-3) during continental conditions associated with high black carbon (BC~2,000 ng m-3) and columnar aerosol loading. During the marine air mass conditions, CCN concentrations diminished to ~ 350 cm-3 at 0.3 % SS and low aerosol loading persisted (BC~900 ng m-3). High CCN activation fraction (AF) of ~ 0.55 (at 0.3 % SS) were observed before the monsoon rainfall, which reduced to ~ 0.15 during the monsoon and enhanced to ~ 0.32 after that. Mostly mono-modal aerosol number-size distribution (NSD) with a mean geometric mean diameter (GMD) of ~ 85 nm, with least (~ 9 %) contribution from nucleation mode (
Modifying the Jackson index to quantify the relationship between geology, landscape structure, and water transit time in steep wet headwaters

The relationship between stream water mean transit time (MTT), catchment geology, and landscape structure is still poorly characterized. Here, we present a new simple index that builds on the Jackson, Bitew, and Du (2014) index that focuses specifically on permeability contrasts at the soil–bedrock interface and digital elevation model‐based physical flow path measurements to identify broad landscape trends of moisture redistribution in the subsurface of steep wet headwater catchments. We use this index to explore the relationship between geology, landscape structure, and water transit time through the lens of landscape anisotropy. We hypothesize that catchments with a greater tendency to shed water laterally will correlate with younger stream water MTT and catchments with a greater tendency to infiltrate water vertically will correlate with older stream water MTT. We tested the new index at eight geologically diverse Pacific Rim catchments in Oregon, Japan, and New Zealand. The new index explained 77% of the variability in measured stream water MTT across these varied sites. These findings suggest that critical zone anisotropy and catchment form are first‐order controls on the time scales over which catchments store and release their water and that a simple index may usefully capture this relationship.
Global output tracking by state feedback for high-order nonlinear systems with time-varying delays

Abstract This paper focuses on the problem of global practical output tracking for a class of high-order non-linear systems with time-varying delays (via state feedback). Under mild growth conditions on the system nonlinearities involving time-varying delays, we construct a state feedback controller with an adjustable scaling gain. With the aid of a Lyapunov–Krasovskii functional, the scaling gain is adjusted to dominate the time-delay nonlinearities bounded by the growth conditions and make the tracking error arbitrarily small while all the states of the closed-loop system remain to be bounded. Finally, a simulation example is given to illustrate the effectiveness of the tracking controller.
Do Football Players Train Hard? Difference in Intensity Between Small-Big Sided Games and Matches Through GPS Data

The aim of the study is to compare external load parameters in football when measured during games and in diﬀ erent forms of training (e.g., small and big sided games). Data were collected from 35 football players from a U17 and U19 teams playing for a premier league football academy. All external load parameters were divided into two categories, those related to changes in velocity and those related to diﬀ erent speed zones. Parameters related to changes in velocity were signiﬁ cantly higher in small-sided games compared to matches. Parameters related to speed zones were mostly signiﬁ cantly higher in big sided games compared to matches, except for the parameters weighted total intensity, repeated sprints, ratio of repeated sprints and walking meters. The results show that these parameters are part of the match and are practiced in every training session, and by increasing their intensity in training, these parameters should increase in the matches. Findings can be used to enhance the periodization of training and ultimately player performance.
