Life-Add: Lifetime Adjustable Design for WiFi Networks with Heterogeneous Energy Supplies

WiFi usage significantly reduces the battery lifetime of handheld devices such as smartphones and tablets, due to its high energy consumption. In this paper, we propose "Life-Add": a Lifetime Adjustable design for WiFi networks, where the devices are powered by battery, electric power, and/or renewable energy. In Life-Add, a device turns off its radio to save energy when the channel is sensed to be busy, and sleeps for a random time period before sensing the channel again. Life-Add carefully controls the devices' average sleep periods to improve their throughput while satisfying their operation time requirement. It is proven that Life-Add achieves near-optimal proportional-fair utility performance for single access point (AP) scenarios. Moreover, Life-Add alleviates the near-far effect and hidden terminal problem in general multiple AP scenarios. Our ns-3 simulations show that Life-Add simultaneously improves the lifetime, throughput, and fairness performance of WiFi networks, and coexists harmoniously with IEEE 802.11.Comment: This is the technical report of our WiOpt paper. The paper received the best student paper award at IEEE WiOpt 2013. The first three authors are co-primary author

Dental Health Insurance in India: Need of the Hour!

India is a vast country of diverse cultures and languages. People of the Indian subcontinent lack sufficient knowledge about dentistry as a science, thus making it a necessity to provide dental care to the masses. High cost of dental treatment and lesser oral health practices among people in India predispose to altered oral hygiene. Dental Insurance in India is of great relevance in making oral care facilities available to one and all. However, it has just completed its first step, and only few insurance organizations are giving dental insurance provision, in contrast to the medical insurance companies which cover most of the Indian population. Therefore, the main objective of this review paper was to assess the provision of oral health insurance schemes in the Indian subcontinent and their knowledge and utilization by Indian public. For this, we studied the articles published in last few years from various sources regarding dental insurance in India. It was revealed that currently, there are only a few dental insurance policies, but with time and modern resources, dental insurance schemes in India will surely increase. As time progresses, a stage will be reached where each and every Indian will be protected by a trustworthy Dental Insurance scheme

Inter-Kingdom Signaling Interactions in Enterohemorrhagic Escherichia coli Infections

The overall goal of this research was to understand the role of inter-kingdom signaling in enterohemorrhagic Escherichia coli (EHEC) infections of the human gastro-intestinal (GI) tract from the perspective of both the invading pathogen and the human intestinal epithelial cells, which they colonize. Differential gene expression of EHEC was studied upon exposure to the human neuroendocrine hormones epinephrine and norepinephrine. We determined that these hormones increase EHEC chemotaxis, motility, biofilm formation, colonization of host cells, and virulence gene expression. We also studied the EHEC response to the GI tract commensal bacterial signaling molecules indole and autoinducer-2 (AI-2). We observed that indole decreases all the EHEC phenotypes that are increased by the human hormones and represses EHEC virulence. However, the effect of AI-2 was similar to that observed with hormones and opposite to that observed with indole, i.e. AI-2 increases EHEC virulence phenotypes. We studied changes in host cell transcriptome in the presence of the commensal bacterial signal indole. Indole increases expression of genes involved in tight junction and gap junction formation, and production of mucins and actin cytoskeleton genes. Indole also down-regulates genes encoding for pro-inflammatory cytokines, chemokines, and Toll-like receptors. The gene expression results were confirmed with phenotypic assays where we observed an increase in trans-epithelial resistance, increase in the anti-inflammatory cytokine IL-10, decrease in the pro-inflammatory cytokine IL-8, decrease in the activity of the pro-inflammatory transcription factor NF-κB, and decrease in colonization by EHEC of the indole-pre-treated HCT-8 cells. We established that factors secreted by epithelial cells are important determinants of EHEC virulence. Gene expression studies showed that 34 out of 41 LEE virulence genes were induced when EHEC was cultured in conditioned medium. In addition, the data showed increased expression of the shiga toxin-2 prophage 933W. These changes in gene expression were corroborated by a 5-fold increase in HCT-8 cell colonization and increased intracellular Stx2 phage titers. We determined that the HCT-8-secreted factor(s) was protein-based and that it was greater than 3 kDa in size. In conclusion, we have characterized the pathogen response to various eukaryotic and prokaryotic GI tract signals. We have established, for the first time, that the commensal bacterial signal indole is an inter-kingdom signal for the host epithelial cells. Overall, our studies provide a greater understanding of host-pathogen interactions

Ergonomics: Need of the Hour

The success in any practice is dependent on efficient workflow, with minimum risk to injury and cumulative trauma. Work in a dental office calls for deftness in cognitive abilities and can, more often than not, be physically challenging. Repeated use of movements and postures that go against the natural or anatomical alignment and limitations of the human body often lead to what is known as cumulative trauma leading to development of musculoskeletal disorders. The whole idea of ergonomics in the workplace is to avoid any such exigencies. Through this review it is intended to bring forth the widely known yet often neglected aspect of dental practice; that is the human factor in workplace efficiency

External oblique intercostal block in open nephrectomy patients - A zenith in analgesia for anterolateral upper abdominal surgeries: A case series

Open nephrectomy is a common surgery usually performed for malignant and non-malignant renal pathologies. The external oblique intercostal block (EOIB) blocks the anterior and lateral cutaneous nerves from T6 to T10 and provides somatic analgesia. We present a case series of the use of EOIB in patients undergoing open nephrectomy by subcostal incision. Ten patients were given EOIB, which included patients undergoing simple nephrectomy for non-functioning kidneys and radical nephrectomy for renal mass. The patients had satisfactory numerical rating scale scores, mostly <4 for 24 h. Post-operative opioid consumption was minimal. The external oblique fascial plain block is a novel thoracic block that provides reliable upper thoracoabdominal somatic analgesia. It can certainly be considered a suitable option in surgeries such as nephrectomies that involve an upper lateral abdominal wall incision

Sponge based CCA2 secure asymmetric encryption for arbitrary length message

OAEP and other similar schemes proven secure in Random-Oracle Model require one or more hash functions with output size larger than those of standard hash functions. In this paper, we show that by utilizing popular Sponge constructions in OAEP framework, we can eliminate the need of such hash functions. We provide a new scheme in OAEP framework based on Sponge construction and call our scheme \textit{Sponge based asymmetric encryption padding} (SpAEP). SpAEP is based on 2 functions: Sponge and SpongeWrap, and requires only standard output sizes proposed and standardized for Sponge functions. Our scheme is CCA2 secure for any trapdoor one-way permutation in the ideal permutation model for arbitrary length messages. Our scheme utilizes the versatile Sponge function to enhance the capability and efficiency of the OAEP framework. SpAEP with any trapdoor one-way permutation can also be used as a key encapsulation mechanism and a tag-based key encapsulation mechanism for hybrid encryption. Our scheme SpAEP utilizes the permutation model efficiently in the setting of public key encryption in a novel manner

Automatic Personalization of User Interfaces based on User Interaction Analytics

The default user interface (UI) of software applications is the same for all users, even though users differ in terms of their needs and preferences for using the software. UI customization is typically limited to the most advanced and/or highly active users. As a result, a significant proportion of users of a software do not reap the benefits of having a UI that is personalized to them. This disclosure describes techniques to determine and present a personalized UI to each user or an application, with the user’s permission. UI personalization is performed based on analytics of user-permitted data of user interaction and other relevant information. The analysis can be performed by a suitably trained machine learning model which outputs the optimal personalized UI for each user. Model training and execution is performed on the user device, and if the user permits, on a server that trains the model based on aggregated, non-identifiable user data
