On the specification property and synchronization of unique q expansions
Venue: Ergodic Theory and Dynamical Systems
Year: 2020

Given a positive integer M and $q \in (1, M+1] we consider expansions in base q for real numbers $x \in [0, {M}{q 1} over the alphabet {0, \ldots M\ In particular, we study some dynamical properties of the natural occurring subshift \boldsymbol{{V}}_q, \sigma related to unique expansions in such base q. We characterize the set of $q \in \mathcal {V} \subset (1,M+1] such that \boldsymbol{{V}}_q, \sigma has the specification property and the set of $q \in \mathcal {V} such that \boldsymbol{{V}}_q, \sigma is a synchronized subshift. Such properties are studied by analysing the combinatorial and dynamical properties of the quasi greedy expansion of q. We also calculate the size of such classes as subsets of \mathcal {V} giving similar results to those shown by Blanchard 10 and Schmeling in 36 in the context of \beta transformations.
Photoorganocatalysis, small organic molecules and light in the service of organic synthesis: the awakening of a sleeping giant.
Venue: Organic biomolecular chemistry
Year: 2018

Photocatalysis, the use of light to promote organic transformations, is a field of catalysis that has received limited attention despite existing for over 100 years. With the revolution of photoredox catalysis in 2008, the rebirth or awakening of the field of photoorganocatalysis has brought new ideas and reactions to organic synthesis. This review will focus on the sudden outburst of literature regarding the use of small organic molecules as photocatalysts after 2013. In particular, it will focus on acridinium salts, benzophenones, pyrylium salts, thioxanthone derivatives, phenylglyoxylic acid, BODIPYs, flavin derivatives, and classes of organic molecules as catalysts for the photocatalytic generation of C C and C X bonds.
Organ Specific Differences in Alteration of Aquaporin Expression in Rats Treated with Sennoside A, Senna Anthraquinones and Rhubarb Anthraquinones
Venue: International journal of molecular sciences
Year: 2021

Senna and rhubarb are often used as routine laxatives, but there are differences in mechanism of action and potential side effects. Here, we studied metabolites of senna anthraquinones (SAQ) rhubarb anthraquinones (RAQ) and their chemical marker, sennoside A (SA) in a rat diarrhea model. In in vitro biotransformation experiments, SAQ, RAQ and SA were incubated with rat fecal flora solution and the metabolites produced were analyzed using HPLC. In in vivo studies, the same compounds were investigated for purgation induction, with measurement of histopathology and Aqps gene expression in six organs. The results indicated that SAQ and RAQ had similar principal constituents but could be degraded into different metabolites. A similar profile of Aqps down regulation for all compounds was seen in the colon, suggesting a similar mechanism of action for purgation. However, in the kidneys and livers of the diarrhea rats, down regulation of Aqps was found in the RAQ rats whereas up regulation of Aqps was seen in the SAQ rats. Furthermore, the RAQ rats showed lower Aqp2 protein expression in the kidneys, whilst the SA rats and SAQ rats had higher Aqp2 protein expression in the kidneys. This may have implications for side effects of SAQ or RAQ in patients with chronic kidney or liver diseases.
5 blogposts for Fotomuseum Winthertur: 'The Fire Last Time: Documentary and Politics in 1970s Britain'
Year: 2017

In a time of crisis and increasing anti capitalism, I consider the meeting of the political Left with photography in Britain in the 1970s. In the process, I insist the fortunes of documentary and the visibility of social class are entwined. Beginning from a discussion of the critical fortunes of documentary over the last 30 years, I look at the interest in Brecht and the fall out from the so called neo Brechtian moment. In the process, he re evaluates theories and practices of documentary, engaging with a range of documentary work; conceptions of skill and collective production and women and labour.

Exploring Effective Factors in the Demographic and Motivation Issues of the Banking Sector of Bangladesh
Year: 2020

The paper attempted to explore the most effective factors of demographic outlined affecting employees' motivation. With a view to empirical analysis data were collected from 400 bank employees. In the demographic issues gender, age, experience, pay, type and name of the bank, present and prior designations etc. were considered. For inferential statistics there were five regression models with ANOVA and coefficients models developed in the study. The dependent variables were namely work experience, present basic and gross salary, and initial basic and gross salary and 94% 77% 68% 48% and 35% respectively explained by other independent predictors. The study found that work experience was strongly affected by age. On the other hand, present pay (basic and gross) was highly subjective by present designation and initial basic and gross salaries were prejudiced by initial or first joining designation of the employees. The study was also observed on findings that age, present and first joining designations modify employees' motivation in the banking sector of Bangladesh (showed in Table 18)
Security Assessment for Key Management in Mobile Ad Hoc Networks
Year: 2014

A mobile ad hoc network (MANET) is a kind of wireless communication system that doesn't have base stations or routers. The wireless connections can be a standard Wi Fi connection or satellite, or another medium such as a cellular transmission. Specific applications like military or public emergency require secure group communication in ad hoc environments. Good Key management is very important to get protection in any communication system. This paper presents most problems of securing key management in ad hoc networks. It presents a survey of different types of key management protocols in wired networks and in ad hoc networks. It presents the most common kinds of attacks in ad hoc networks. A new efficient approach is proposed. It is based on dividing the members into clusters. This scheme assumes a maximum allowed number of members in each cluster. This reduces the required number of encryption and decryption operations for each join operation in the cluster. This is most suitable for Mobile Ad hoc Networks.
Confirmation of thermal dose as a predictor of local control in cervical carcinoma patients treated with state of the art radiation therapy and hyperthermia.
Venue: Radiotherapy and oncology journal of the European Society for Therapeutic Radiology and Oncology
Year: 2019

Addition of deep hyperthermia results in improved local control (LC) and overall survival (OS) compared to radiotherapy alone in patients with cervical carcinoma. Previously, we showed that the thermal dose of hyperthermia significantly correlates with LC and disease specific survival (DSS) Over the last decade, new radiation techniques were introduced resulting in improved LC.  To validate the effect of thermal dose in a more recent cohort of patients treated with modern radiotherapy techniques, including image guided brachytherapy (IGBT) METHODS We analyzed primary cervical carcinoma patients treated with a combination of radiotherapy and deep hyperthermia between 2005 and 2016 at our institute. Data on patient, tumor and treatment were collected including the thermal dose parameters TRISE and CEM43T90. Follow up data on LC, disease free survival, DSS, OS as well as late toxicity data were collected. Data were analyzed using the Cox proportional hazard and Kaplan Meier analyses.  227 patients were included. In multivariate analysis, histology, FIGO stage, lymphadenopathy, TRISE, CEM43T90 and IGBT had a significant effect on LC. In the patients treated with IGBT, the thermal dose parameter TRISE remained to have a significant effect on LC in univariate analysis.  The positive association between thermal dose and clinical outcome is replicated in an independent, recent cohort of cervical carcinoma patients. Importantly, in patients receiving IGBT, the effect of thermal dose on clinical outcome is still observed.

Ultra small freestanding amorphous molybdenum sulfide colloidal nanodots for highly efficient photocatalytic hydrogen evolution reaction
Year: 2018

Recently, molybdenum sulfide with its amorphous counterpart was found to hold a high activity versus the hydrogen evolution reaction (HER) making it a high potential material to explore new HER catalysts. Here we present a facile chemical method to synthesize ultra small freestanding amorphous molybdenum sulfide (a MoSx) colloidal nanodots with diameter of lower than 2 nm. Electrocatalytic HER tests show that freestanding a MoSx colloidal nanodots exhibit an enhanced catalytic hydrogen activity in stark in contrast with in situ annealed c MoS2. When applied as a co catalyst in photocatalytic HER, ultra small a MoSx nanodots could form a compact interface with the TiO2 when assisted by a bifunctional molecular linker, as the mercaptopropionic acid (MPA) which facilitates the decrease of the interfacial Schottky barrier occurring between the two components and allows for a fast injection of photo excited electrons from the photoharvester into the co catalyst. Our results demonstrate that the drastic enhancement of the photocatalytic H2 promotion rate of a MoSx@MPA TiO2 is mainly provided by unsaturated Mo(IV) active sites generated by the in situ reduction during the photocatalytic HER process. The synergistic effect of generated unsaturated Mo(IV) sites and the presence of more exposed intrinsic active edges further promotes the enhancement of the catalytic H2 activity on a MoSx nanodots.
Persistent Sharing of Fitness App Status on Twitter
Venue: CSCW
Year: 2016

As the world becomes more digitized and interconnected, information that was once considered to be private such as one's health status is now being shared publicly. To understand this new phenomenon better, it is crucial to study what types of health information are being shared on social media and why, as well as by whom. In this paper, we study the traits of users who share their personal health and fitness related information on social media by analyzing fitness status updates that MyFitnessPal users have shared via Twitter. We investigate how certain features like user profile, fitness activity, and fitness network in social media can potentially impact the long term engagement of fitness app users. We also discuss implications of our findings to achieve a better retention of these users and to promote more sharing of their status updates.
Endogenous DNA Damage as a Source of Genomic Instability in Cancer
Venue: Cell
Year: 2017

Genome instability, defined as higher than normal rates of mutation, is a double edged sword. As a source of genetic diversity and natural selection, mutations are beneficial for evolution. On the other hand, genomic instability can have catastrophic consequences for age related diseases such as cancer. Mutations arise either from inactivation of DNA repair pathways or in a repair competent background due to genotoxic stress from celluar processes such as transcription and replication that overwhelm high fidelity DNA repair. Here, we review recent studies that shed light on endogenous sources of mutation and epigenomic features that promote genomic instability during cancer evolution.

Effects of dietary supplementation of cinnamaldehyde and formic acid on growth performance, intestinal microbiota and immune response in broiler chickens
Year: 2017

An experiment was conducted to investigate the effects of replacing antibiotic growth promoter (AGP) with a combination of essential oil and organic acids (EO OA) on growth performance, gut microbiota and immune response in broiler chickens. In Experiment 1, 320 day old broiler chicks were randomly distributed to 32 pens with 10 birds in each pen and the pens were equally allotted to four treatment groups. In Experiment 2, 120 day old chicks were divided into the same four treatment groups, each group containing three replicated pens with 10 birds in each pen. The groups were (1) Negative Control (NC) without AGP or other growth promoting feed additives; (2) AGP (NC enramycin; 125 mg/kg feed; (3) OA (NC OA; 500 mg/kg feed) and (4) EO OA (NC a combination of cinnamaldehyde and calcium formate; 500 mg/kg feed) Experiment 1 lasted for 40 days, whereas Experiment 2 continued for 28 days. In Experiment 2, all birds were orally challenged with Escherichia coli (108 bacteria/bird) on Day 14. Overall intake, growth and feed conversion ratio (FCR) on Day 40 had no difference (P 0.05) among the groups in Experiment 1. In Experiment 2, growth, feed intake and FCR were not affected by any dietary treatments until Day 14, but after being challenged with E. coli, bodyweight gain and FCR improved (P 0.05) the counts of total bacteria, E. coli and Lactobacillus in the contents of ileum and caecum. However, Salmonella counts in the ileal and caecal contents decreased (P 0.001) for AGP, OA and EO OA compared with NC group. Clostridium counts were lower for EO OA group than for NC and AGP groups in the ileum, and for AGP, OA and EO OA groups than for NC in the caeca (P 0.05) Antibody titer on Day 35 against Newcastle disease vaccine was higher in EO OA group than in NC, AGP and OA groups (P 0.001) In conclusion, EO OA did not affect growth and FCR in broilers. However, AGP and EO AO improved growth performance and FCR after being challenged with E. coli. Moreover, EO OA was effective in reducing the Clostridium count in the small intestine and caecum and increasing the villus height and antibody titer against Newcastle disease vaccine.
Semantic Enhanced Training Data Augmentation Methods for Long Tail Entity Recognition Models
Year: 2020

Named Entity Recognition (NER) is an essential information retrieval task. It enables a wide range of natural language processing applications such as semantic search, machine translation, etc. The NER can be formulated as the task of identifying and typing words or phrases in a text that refers to certain classes of interest (e.g. disease, Adverse Drug Reactions) There are different techniques to tackle NER, such as dictionary based, rulebased, and machine learning based. Machine learning based NER techniques have shown to perform the best for entities with large amounts of human labeled training datasets. However, their performance is limited when dealing with long tail entities. Long tail entities are entities that have a low frequency in the document collections and usually have no reference to existing Knowledge Bases. Obtaining human labeled datasets is expensive and time consuming, especially for long tail entities that are scarcely available in document collections. This dissertation focuses on the problem of the lack of training data, arguably the largest bottleneck in training machine learning based NER techniques. We investigated efficient and effective ways to augment training data by enhancing their size and quality automatically. Our work aimed at showing how, by enhancing the size and quality of the training data using different techniques, it will be possible to improve the performance of Long tail Entity Recognition (L tER)

Concentrated solar power: Recent developments and future challenges
Year: 2015

With the mass manufacture and resulting low cost of silicon photovoltaics driven by Western government subsidy schemes and large scale manufacturing, concentrated solar power for electricity generation is now at a turning point. The present cost of mirrors, lenses, support structure and plant for concentrated solar thermal power, and of the high efficiency multi junction cells, concentrating optics and two axis tracking systems for concentrated photovoltaic power, has made operational concentrated solar power plants uncompetitive in most scenarios. This is changing the shape of optics as well as the materials from which they are constructed and the size of the components used. We aim to highlight the current research that is being carried out to reduce the cost of concentrated solar power and concentrate on the long term potential for cost reduction of both concentrated solar power technologies. This review concentrates first on optical and thermodynamic fundamentals, and the technology choices imposed by real world materials. We then review the broad categories of optical concentrators. Developments in solar thermal power generation and heat and thermochemical storage are discussed before briefly describing recent research on thermoelectric generation. Recent trends in concentrated photovoltaics are summarised, and we conclude by considering the present situation for concentrated solar power in the context of mass market silicon photovoltaics.
Ethnic inequalities in health between Arabs and Jews in Israel: the relative contribution of individual level factors and the living environment
Venue: International Journal of Public Health
Year: 2017

ObjectivesEthnic inequalities in health (EIH) are unjust public health problem that emerge across societies. In Israel, despite uniform healthcare coverage, marked EIH persist between Arabs and Jews.MethodsWe draw on the ecosocial approach to examine the relative contributions of individual socioeconomic status (SES) psychosocial and health behavioral factors, and the living environment (neighborhood problems, social capital, and social participation) to explaining ethnic differences in self rated health (SRH) Data were derived from two nationwide studies conducted in 2004 2005 of stratified samples of Arabs (N 902) and Jews (N 1087).ResultsPoor SRH was significantly higher among Arabs after adjustment for age and gender [odds ratio and 95% confidence interval (CI) 1.94 (1.57 2.40) This association was reversed following adjustment for all possible mediators: OR (95% CI) 0.70(0.53 0.92) The relative contribution of SES and the living environment was sizable, each attenuating the EIH by 40% psychosocial factors by 25% and health behaviors by 16%.ConclusionsArabs in Israel have poorer SRH than Jews. Polices to reduce this inequality should mainly focus on improving the SES and the living conditions of the Arabs, which might enhance health behaviors and well being.
