Year: 2012

The growth and biochemical effects of different plant hormones on virus free potato seedlings were studied in hope of providing theoretic basis for Potato Micro tuber production.The results of the study showed that the plant hormones(1)greatly improved the root growth vigor and potentials of the potato seedlings and increased the root protein content of the seedlings;(2)Evidently increased the net photosynthetic rate,dry matter,chlorophyll content as well as photosynthate accumulation of the seedlings;(3)Increased evidently the activities of SOD,POD,CAT and the free amino acid content and decreased the content of MDA;(4)Significantly promoted the potato seedlings which were better to have a mini tuber number and yield per plant.Thereinto,with NAA at 100 mg/L,IBA at 50 mg/L and boric acid at 17.5 mg/L,the photosynthetic pigment content,net photosynthetic rate,protective enzyme activities,free amino acid content of the seedlings were the most favorable and the mini tuber number and yield per plant appeared the highest as well.
Development of a High Flow Nasal Cannula and Pharmaceutical Aerosol Combination Device.
Venue: Journal of aerosol medicine and pulmonary drug delivery
Year: 2019

Aerosol drug delivery to the lungs is known to be very inefficient during all forms of noninvasive ventilation, especially when the aerosol is administered simultaneously with high flow nasal cannula (HFNC) therapy. The objective of this study was to develop a new combination device based on vibrating mesh nebulizers that can provide continuously heated and humidified HFNC therapy as well as on demand pharmaceutical aerosols with high efficiency.  The combination device implemented separate mesh nebulizers for generating humidity (humidity nebulizer) and delivering the medical aerosol (drug nebulizer) Nebulizers were actuated in an alternating manner with the drug nebulizer delivering the medication during a portion of an adult inhalation cycle. Aerosol entered a small volume mixing region where it was combined with ventilation gas flow and then entered a heating channel to produce small particles that are desirable for nose to lung administration and potentially excipient enhanced growth delivery. Three assessment methods (analytical calculations, computational fluid dynamics [CFD] simulations, and in vitro experiments in three dimensional [3D] printed devices) were used to improve the mixer heater design to minimize depositional drug losses, maintain a small device volume, ensure sufficient droplet evaporation, and control the outlet thermodynamic conditions.  For an initial configuration (Design 1) good agreement in performance metrics was found using the three assessment methods. Based on insights gained from the CFD simulations of Design 1, two new designs were developed and produced with 3D printing. Experimental analysis indicated that the new designs both achieved <5% depositional loss in the mixer heater even with cyclic operation and sufficiently dried the aerosol from an initial size of 5.3 mm to an outlet size of ~1.0 mm. A combination of the applied methods indicated that the desired thermodynamic conditions of HFNC therapy were also met.  Multiple methodological approaches were used concurrently to develop a new combination device for administering HFNC therapy and simultaneous on demand pharmaceutical aerosols to the lungs with high efficiency. The use of a small volume mixer heater <100 mL) synchronization of the drug nebulizer with inhalation, and small outlet particle size should enable high efficiency lung delivery of the aerosol.
Automatic tongue contour extraction in ultrasound images with convolutional neural networks
Year: 2018

Ultrasound imaging of the tongue can provide detailed articulatory information addressing a variety of phonetic questions. However, using this method often requires the time consuming process of manually labeling tongue contours in noisy images. This study presents a method for the automatic identification and extraction of tongue contours using convolutional neural networks, a machine learning algorithm that has been shown to be highly successful in many biomedical image segmentation tasks. We have adopted the U net architecture (Ronneberger, Fischer, Brox 2015, U Net: Convolutional Networks for Biomedical Image Segmentation, ) which learns from human annotated splines using multiple, repeated convolution and max pooling layers in the network for feature extraction, as well as deconvolution layers for generating spatially precise predictions of the tongue contours. Trained using a preliminary dataset of 8881 human labeled tongue images from three speakers, our model generates discrete tongue splines comparable to those identified by human annotators (Dice Similarity Coefficient 0.71) Although work is ongoing, this neural network based method shows considerable promise for the post processing of ultrasound images in phonetic research.
Prevention of Cognitive Decline in Alzheimer's Disease by Novel Antioxidative Supplements
Venue: International journal of molecular sciences
Year: 2020

Oxidative stress plays a crucial role in Alzheimer's disease (AD) from its prodromal stage of mild cognitive impairment. There is an interplay between oxidative stress and the amyloid b (Ab) cascade via various mechanisms including mitochondrial dysfunction, lipid peroxidation, protein oxidation, glycoxidation, deoxyribonucleotide acid damage, altered antioxidant defense, impaired amyloid clearance, inflammation and chronic cerebral hypoperfusion. Based on findings that indicate that oxidative stress plays a major role in AD, oxidative stress has been considered as a therapeutic target of AD. In spite of favorable preclinical study outcomes, previous antioxidative components, including a single antioxidative supplement such as vitamin C, vitamin E or their mixtures, did not clearly show any therapeutic effect on cognitive decline in AD. However, novel antioxidative supplements can be beneficial for AD patients. In this review, we summarize the interplay between oxidative stress and the Ab cascade, and introduce novel antioxidative supplements expected to prevent cognitive decline in AD.
The death of the author

It takes skill to change a person's attitude, even slightly, especially when that person is, like me, obdurate by nature and past middle age in the life cycle. But Professor David Ellis, author of the lucid and moving Death and the Author: How D H Lawrence Died, and Was Remembered ( 2008) has caused me to revise upwards my opinion of Lawrence, at least as a man if not as a writer. Lawrence died from tuberculosis, of course, as did many other writers. So many of them, in fact, died from the disease that one is inclined to suppose that it was an occupational hazard of a devotion to literature: proof, no doubt, of the danger of
Effects of potato resistant starch intake on insulin sensitivity, related metabolic markers and appetite ratings in men and women at risk for type 2 diabetes: a pilot cross over randomised controlled trial
Venue: Journal of human nutrition and dietetics the official journal of the British Dietetic Association
Year: 2020

The intake of certain types of resistant starch (RS) has been associated in some studies with increased whole body insulin sensitivity. This randomised, cross over pilot trial evaluated the effect of consuming cooked, then chilled potatoes, a source of RS, compared to isoenergetic, carbohydrate (CHO) containing control foods, on insulin sensitivity and related markers.  Nineteen adults with body mass index 27.0 39.9 kg m 2 consumed 300 g day 1 RS enriched potatoes (approximately two potatoes; ~18 g RS) or CHO based control foods, as part of lunch, evening and snack meals, over a 24 h period. After an overnight fast, insulin sensitivity, CHO metabolism markers, free fatty acids, breath hydrogen levels and appetite were assessed for up to 5 h after the intake of a standard breakfast. The primary endpoint was insulin sensitivity, assessed with the Matsuda index. P 0.05 (one sided) was considered statistically significant.  Insulin sensitivity was not significantly different between the potato and control conditions. The potato intervention resulted in higher postprandial breath hydrogen (P 0.037) lower postprandial free fatty acid concentrations (P 0.039) and lower fasting plasma glucose (P 0.043) compared to the control condition. Fullness ratings were significantly lower after potato versus control (P 0.002) No other significant effects were observed; however, there was a trend toward lower fasting insulin (P 0.077) in the potato versus the control condition.  The results of this pilot study suggest RS enriched potatoes may have a favourable impact on carbohydrate metabolism and support the view that additional research in a larger study sample is warranted.
Saber on ESP 32
Year: 2019

Saber, a CCA secure lattice based post quantum key encapsulation scheme, is one of the second round candidate algorithms in the post quantum cryptography standardization process of the US National Institute of Standards and Technology (NIST) in 2019. In this work, we provide an efficient implementation of Saber on ESP32, an embedded microcontroller designed for IoT environment with WiFi and Bluetooth support. RSA coprocessor was used to speed up the polynomial multiplications for Kyber variant in a CHES 2019 paper. We propose an improved implementation utilizing the big integer coprocessor for the polynomial multiplications in Saber, which contains significant lower software overhead and takes a better advantage of the big integer coprocessor on ESP32. By using the fast implementation of polynomial multiplications, our single core version implementation of Saber takes 1639K, 2123K, 2193K clock cycles on ESP32 for key generation, encapsulation and decapsulation respectively. Benefiting from the dual core feature on ESP32, we speed up the implementation of Saber by rearranging the computing steps and assigning proper tasks to two cores executing in parallel. Our dual core version implementation takes 1176K, 1625K, 1514K clock cycles for key generation, encapsulation and decapsulation respectively.

Biochemical Composition and Shelf Life Study of Mixed Fruit Juice from Orange Pineapple
Year: 2015

In present study, fruit juice has been produced in different ratio of pineapple and orange juice. Juices were pasteurized at 97 o C for 5 mins and stored for 35 days in PET bottles at refrigerated temperature. The TSS and pH of the different types of juice were found in the range of 7.73 to 8.53 and 4.33 to 4.53 respectively. Maximum acidity (0.785% and vitamin C (37.1 mg/100 ml) were found in the sample A (in a ratio 1:1) Aerobic plate count was found within the range of (92 x 10 6 to 233x 10 6 cfu/ml. The produced juice blends were subjected to chemical and sensory evaluation at one week interval for five weeks storage time. The chemical analysis showed that, there is a gradual decrease in titratable acidity and Vitamin C along the storage period. TSS and pH increased progressively during storage period. The mean overall acceptability scores of more than 8 for juice samples indicated the commercial scope for manufacturing good and nutritious pineapple juice blended with orange juice. From all the analysis, it can be observed that the juice blend can be kept conveniently for three weeks without preservatives and 28 days with sodium benzoate at the rate of 0.6 mg/L.  2014
Illusory correlations in preschoolers
Year: 2014

People form illusory correlations (ICs) such that they will at times perceive a relationship between variables even when no such relationship exists. Three experiments with undergraduates (N 20) 5 year olds (N 71) and 3 year olds (N 52) explored the origins of ICs: When, and under what conditions, does the disposition to form ICs emerge? Results showed that, like adults, 5 year olds formed ICs for large samples of evidence (Experiment 1) but 5 year olds did not do so for smaller samples (Experiment 2) Three and 5 year olds formed ICs for small samples when the evidence was presented in a way that promoted an attention shift from one category to the other during category learning (Experiment 3) These results suggest ICs are due, in large part, to limitations in processing capacity and biases in attentional learning mechanisms. The results provide insights regarding the conditions that influence children's ability to detect and use regularities in the available input and thus have implications for understanding their performance on a broad range of cognitive tasks.
Circumventing iOS security mechanisms for APT forensic investigations: A security taxonomy for cloud apps
Venue: Future Gener. Comput. Syst.
Year: 2018

Mobile devices and apps such as cloud apps are a potential attack vector in an advanced persistent threat (APT) incident, due to their capability to store sensitive data (e.g. backup of private and personal data in digital repositories) and access sensitive resources (e.g. compromising the device to access an organisational network) These devices and apps are, thus, a rich source of digital evidence. It is vital to be able to identify artefacts of forensic interest transmitted to/from and stored on the devices. However, security mechanisms in mobile platforms and apps can complicate the forensic acquisition of data. In this paper, we present techniques to circumvent security mechanisms and facilitate collection of artefacts from cloud apps. We then demonstrate the utility of the circumvention techniques using 18 popular iOS cloud apps as case studies. Based on the findings, we present the first iOS cloud app security taxonomy that could be used in the investigation of an APT incident.

Trait changes in a harvested population are driven by a dynamic tug of war between natural and harvest selection
Venue: Proceedings of the National Academy of Sciences
Year: 2007

Selective harvest of large individuals should alter natural adaptive landscapes and drive evolution toward reduced somatic growth and increased reproductive investment. However, few studies have simultaneously considered the relative importance of artificial and natural selection in driving trait changes in wild populations. Using 50 years of individual based data on Windermere pike (Esox lucius) we show that trait changes tracked the adaptive peak, which moved in the direction imposed by the dominating selective force. Individual lifetime somatic growth decreased at the start of the time series because harvest selection was strong and natural selection was too weak to override the strength of harvest selection. However, natural selection favoring fast somatic growth strengthened across the time series in parallel with the increase in pike abundance and, presumably, cannibalism. Harvest selection was overridden by natural selection when the fishing effort dwindled, triggering a rapid increase in pike somatic growth. The two selective forces appear to have acted in concert during only one short period of prey collapse that favored slow growing pike. Moreover, increased somatic growth occurred concurrently with a reduction in reproductive investment in young and small female pike, indicating a tradeoff between growth and reproduction. The age specific amplitude of this change paralleled the age specific strength of harvest pressure, suggesting that reduced investment was also a response to increased life expectancy. This is the first study to demonstrate that a consideration of both natural selection and artificial selection is needed to fully explain time varying trait dynamics in harvested populations.
The Open Society and coach education: a philosophical agenda for policy reform and future sociological research
Year: 2015

The realisation of the strategic importance of high quality coaching to the achievement of national sport policy objectives is resulting in extensive movements to professionalise the coaching industry. Interest in coach education is therefore growing among academics and policy makers alike. A recent review of literature in this field, however, reveals a troubling problem situation: formal coach education is important for coach learning but tends to be expensive, inflexible and overly technical and therefore has little real impact on coaching practice. The solutions offered by many academics are, unfortunately, vague and often philosophically flawed. This is particularly so when the descriptive model of communities of practice (CoP) is suggested as a prescriptive model for coach education. The first part of the paper, therefore, ends with an extended critique of the use of CoP as a model for coach education.  To provide a clear philosophical argument for the direction of reform for coach education, drawing on a normative theory of the ideal conditions for the growth of knowledge.  Starting with the argument that any descriptive (or 'evidence based' model is inherently conservative, the second part of the paper offers an alternative solution to the problem of coach education that is openly prescriptive (or normative) It is the Popperian ideal type of an Open Society (OS) It is argued that the concept of an OS is a better prescriptive model for coach learning for a number of reasons. First, it is based on a logically sound epistemological theory of the ideal social conditions for the growth of knowledge. Second, it is simple and easy for lay people to understand. Third, as an ideal type, it offers a target or goal against which progress towards a better method of coach education can be measured. In this final sense, it also offers a clear agenda for policy reform and future sociological research.  The paper makes a series of practical recommendations for reforming coach education and its institutions based on the model of the OS. Foremost among these are making learning resources free at the point of use and using Web 2.0 technologies to democratise educational episodes and widen participation in coach education programmes of all kinds.
