On Matching Finger-Selfies Using Deep Scattering Networks (2020)

With the advancements in technology, smartphones' capabilities have increased immensely. For instance, the smartphone cameras are being used for face and ocular biometric-based authentication. This research proposes finger-selfie based authentication mechanism, which uses a smartphone camera to acquire a selfie of a finger. In addition to personal device-level authentication, finger-selfies may also be matched with livescan fingerprints present in the legacy/national ID databases for remote or touchless authentication. We propose an algorithm which comprises segmentation, enhancement, Deep Scattering Network based feature extraction, and Random Decision Forest to authenticate finger-selfies. This paper also presents one of the largest finger-selfie database with over 19, 400 images. The images in the IIIT-D Smartphone Finger-selfie Database v2 are captured using multiple smartphones and include variations due to background, illumination, resolution, and sensors. Results and comparison with existing algorithms show the efficacy of the proposed algorithm which yields equal error rates in the range of 2.1 - 5.2% for different experimental protocols.

The role of ion channels in stomatal action, phloem physiology, and nutrient uptake – molecular and biophysical analysis (2001)

Ion uptake from the soil and distribution within the plant body requires the co-ordinate function of differentially expressed ion channels and carriers. Individual members of the K+ channel family are involved in nutrient uptake, loading into the xylem and phloem as well as the physiology of stomatal movement. After finishing the sequence of the Arabidopsis genome, information about the entire set of ion channel genes is available. To unravel the physiological role of individual ion channel genes for plant growth and development we analysed distinct loss-of-channel function mutants. In this context we studied the cell-type specific expression pattern of K+ channel genes by real-time quantitative RT-PCR and the biophysical properties using various electrophysical techniques. Guard Cell: Due to ion channel homeostasis, plants lacking the dominant K+ uptake channel, KAT1, exhibited normal stomatal function (Szyroki et al. 2001). Root hair: Pronounced phenotypes were observed with Arabidopsis root hairs, which lacked expression of distinct K+ channels (Ivashikina et al. 2001, subm.; Reintanz et al. 2001, subm.). Phloem: In order to determine the role of ion channels in phloem physiology, we identified the AKT2/3-type channels (Marten et al. 1999; Philippar et al. 1999; Bauer et al. 2000; Ache et al. accepted). Expression of AKT2/3 in Arabidopsis is controlled by CO2 and light (Deeken et al. 2000). From the photosynthate-dependency of AKT2/3 and the phenotype of the respective knockout mutant (Deeken et al. subm.) we propose that the coupling between sugar production and allocation involves this peculiar phloem K+ channel.
AIR POLLUTION EXPOSURE AND TELOMERE LENGTH IN HIGHLY EXPOSED SUBJECTS IN BEIJING, CHINA (2011)

Background and Aims. Shortened leukocyte telomere length (LTL) is a marker of cardiovascular risk that has been recently associated w ith long-term exposure to ambient particulate matter (PM). How ever, LTL is increased during acute inflammation, allow ing for rapid proliferation of inflammatory cells. Whether short-term ambient PM exposure increases LTL has not been evaluated. Methods. The Beijing Truck-Driver Air Pollution Study w as conducted shortly before the 2008 Olympic Games (June 15-July 27, 2008) and included 60 truck drivers and 60 office workers. Personal PM2.5 and Black Carbon (BC, a tracer of traffic particles) measured during work hours using portable monitors, and post-work blood samples w ere obtained on two different days separated by 1-2 weeks. Blood LTL was measured by real-time PCR and expressed in relative units. Ambient PM10 was averaged from 27 monitoring stations operating in Beijing. We have regressed log-transformed LTL over exposure variables (occupational group, personal PM2.5, personal BC, or ambient PM10) in mixed-effect models adjusted for age, gender, BMI, day of week, cigarettes/day, central heating, commuting time/day, outdoor temperature, and dew point. Results. Mean personal PM2.5 was 126.8 µg/m3 (inter-quartile range[IQR]:73.9-160.5) in drivers and 94.6 µg/m3 (IQR:48.5-126.6) in office w orkers (p&lt;0.001). Covariate-adjusted LTL means were higher in drivers (0.87, 95%CI:0.74-1.03) relative to office w orkers (0.79, 95%CI:0.67-0.93; p=0.001). In all subjects combined, w e estimated a 5.2% (95%CI:1.5-9.1, p=0.007) increase in LTL per an IQR increase in personal PM2.5. LTL w as also positively correlated with personal BC (+4.9%, 95%CI:1.2-8.8, p=0.01), and with average ambient PM10 on the study day (+7.7%, 95%CI:3.7-11.9, p=0.001) and over the tw o days before (+8.1%, 95%CI:3.1-13.3, p=0.002). Longer PM10 averages (e.g., 5-day) w ere not associated w ith LTL. Conclusions. Our study showed that short-term exposure to ambient PM is associated w ith increased LTL. LTL may favor leukocyte proliferation and sustain the inflammatory mechanisms associated w ith PM health effects.
Functional test of the heart before surgery (2021)

Three new RelE‐homologous mRNA interferases of Escherichia coli differentially induced by environmental stresses (2009)

Prokaryotic toxin - antitoxin (TA) loci encode mRNA interferases that inhibit translation, either by cleaving mRNA codons at the ribosomal A site or by cleaving any RNA site-specifically. So far, seven mRNA interferases of Escherichia coli have been identified, four of which cleave mRNA by a translation-dependent mechanism. Here, we experimentally confirmed the presence of three novel TA loci in E. coli. We found that the yafNO, higBA (ygjNM) and ygiUT loci encode mRNA interferases related to RelE. YafO and HigB cleaved translated mRNA only, while YgiU cleaved RNA site-specifically at GC[A/U], independently of translation. Thus, YgiU is the first RelE-related mRNA interferase that cleaves mRNA independently of translation, in vivo. All three loci were induced by amino acid starvation, and inhibition of translation although to different degrees. Carbon starvation induced only two of the loci. The yafNO locus was induced by DNA damage, but the transcription originated from the dinB promoter. Thus, our results showed that the different TA loci responded differentially to environmental stresses. Induction of the three loci depended on Lon protease that may sense the environmental stresses and activate TA loci by cleavage of the antitoxins. Transcription of the three TA operons was autoregulated by the antitoxins.
Palladium‐Catalyzed Synthesis of Furans from Double Carbonylative Coupling of Aryl Halides with Terminal Alkynes (2013)

Carbonylations and celebrations: A palladium-catalyzed carbonylative coupling of aryl halides with aliphatic alkynes to produce furans has been developed. Aryl iodides and aryl bromides can be applied in this reaction by changing the ligand phosphine ligand from P(o-tolyl)3 for aryl iodides to Xantphos for aryl bromides.

Processor Speed Control With Thermal Constraints (2009)

We consider the problem of adjusting speeds of multiple computer processors, sharing the same thermal environment, such as a chip or multichip package. We assume that the speed of each processor (and associated variables such as power supply voltage) can be controlled, and we model the dissipated power of a processor as a positive and strictly increasing convex function of the speed. We show that the problem of processor speed control subject to thermal constraints for the environment is a convex optimization problem. We present an efficient infeasible-start primal-dual interior-point method for solving the problem. We also present a distributed method, using dual decomposition. Both of these approaches can be interpreted as nonlinear static control laws, which adjust the processor speeds based on the measured temperatures in the system. We give numerical examples to illustrate performance of the algorithms.
Direct Deposition of Micron-Thick Aligned CeramicTiO2Nanofibrous Film on FTOs by Double-Needle Electrospinning Using Air-Turbulence Shielded Disc Collector (2011)

One-dimensional (1D) metal oxides, typically nanowires and nanorods, have unique electronic and optical properties due to quantum phenomena that find applications in modern energy and electronic devices. We present here the electrospinning method that produces the aligned TiO 2 nanofibres directly on the fluorine-doped tin oxide (FTO) substrates mounted rotating disc collector. The aligned TiO 2 ceramic nanofibres mat of 6 μ m thickness is achieved in 4 h using a nonconductive enclosed-air-shield with air-hood design over the FTO mounted rotating disc collector. The aligned TiO 2 nanofibers are found to retain its integrity and binding on FTO surface even after sintering at 500°C. SIMON 8 modeling package is used to determine the behaviour of the charged polymer/TiO 2 jet when single and double needles are used for electrospinning process. The simulation study reveals that the repulsive force of the charged fibers from the double needle exerts stronger electric field distribution along the flow of stream that results in the reduction of the fibers diameter, which is about 28 nm than that of using single-needle system.

Calcipotriol ointment in nail psoriasis: a controlled double-blind comparison with betamethasone dipropionate and salicylic acid (1998)

This double-blind randomized study was designed to compare the efficacy and safety of calcipotriol ointment (50 microg/g) with betamethasone dipropionate (64 mg/g) and salicylic acid (0.03 g/g) ointment in the treatment of nail bed psoriasis. Fifty-eight patients applied the given drug to the affected nails twice a day for 3-5 months, depending on clinical response. Efficacy was assessed monthly on the basis of nail thickness, measured in millimetres. Photographs of the treated nails were taken at baseline, and after 3 and 5 months. Tolerability was assessed at 3 and 5 months. In patients with fingernail psoriasis, after 3 months of treatment subungual hyperkeratosis was reduced from 2.3 +/- 0.1 mm (mean +/- SEM) to 1.5 +/- 0.1 mm (-26.5%) in the calcipotriol group and from 2.3 +/- 0.1 mm to 1.6 +/- 0.1 mm (-30.4%) in the betamethasone dipropionate and salicylic acid group [not significant (NS) between treatments, analysis of variance (ANOVA)]. After 5 months, responders showed a 49.2% reduction in hyperkeratosis in the calcipotriol group (from 2.8 +/- 0.1 mm to 1.4 +/- 0.2 mm) and 51.7% (from 2.1 +/- 0.1 mm to 1.0 +/- 0.1 mm) in the betamethasone dipropionate and salicylic acid group (P < 0.001 from baseline, NS between treatments, ANOVA). In patients with toenail psoriasis, after 3 months of treatment there was an overall reduction in hyperkeratosis from 2.6 +/- 0.1 mm to 2.1 +/- 0.1 mm (-20.1%) in the calcipotriol group and from 3.0 +/- 0.1 mm to 2.3 +/- 0.1 mm (-22. 9%) in the betamethasone dipropionate and salicylic acid group (P < 0.001 from baseline, NS between treatments, ANOVA). By the end of the fifth month there was a 40.7% reduction in hyperkeratosis in the calcipotriol group (from 2.1 +/- 0.1 mm to 1.2 +/- 0.1 mm) and 51.9% in the betamethasone dipropionate and salicylic acid group (from 2.7 +/- 0.1 mm to 1.3 +/- 0.1 mm; P < 0.0001 from baseline, NS between treatments, ANOVA). The results of the study show that calcipotriol is as effective as a combination of a topical steroid with salicylic acid in the treatment of nail psoriasis and represents a safe alternative in the topical treatment of nail psoriasis.
Localization dominance in the median-sagittal plane: Effect of stimulus duration (2004)

Localization dominance is an aspect of the precedence effect (PE) in which the leading source dominates the perceived location of a simulated echo (lagging source). It is known to be robust in the horizontal/azimuthal dimension, where binaural cues dominate localization. However, little is known about localization dominance in conditions that minimize binaural cues, and most models of precedence treat the phenomena as "belonging" to the binaural system. Here, localization dominance in the median-sagittal plane was studied where binaural cues are greatly reduced, and monaural spectral/level cues are thought to be the primary cues used for localization. Lead-lag pairs of noise bursts were presented from locations spaced in 15 degrees increments in the frontal, median-sagittal plane, with a 2-ms delay in their onsets, for source durations of 1, 10, 25, and 50-ms. Intermixed with these trials were single-speaker trials, in which lead and lag were summed and presented from one speaker. Listeners identified the speaker that was nearest to the perceived source location. With single-speaker stimuli, localization improves as signal duration is increased. Furthermore, evidence of elevation compression was found with a dependence on duration. With lead-lag pairs, localization dominance occurs in the median plane, and becomes more robust with increased signal duration. These results suggest that accurate localization of a co-located lead-lag pair is necessary for localization dominance to occur when the lag is spatially separated from the lead.
Studies on Heterologous Antilymphocyte and Antithymocyte Sera (1972)

Abstract The immunosuppressive properties of rabbit and burro anti-mouse lymphocyte sera (ALS) before and after absorption with sheep erythrocytes (SRBC) have been studied. Five out of nine absorbed sera retained their ability to depress splenic plaque-forming cells (PFC) and serum hemagglutinin and hemolysin titers of mice immunized with SRBC. Four sera completely lost their immunosuppressive activity. Seven of the nine ALS had low titer anti-SRBC antibodies, but their complete removal by absorption did not reduce the potency of five of these sera indicating that their immunosuppressive activity was independent of passively transferred heterophile antibodies. The ability of absorbed ALS to prolong mean survival time of A/J to C57BL/6 skin allografts was significantly reduced when compared to that recorded in mice treated with unabsorbed ALS (16.2 vs 23.8 days). These findings are most consistent with the interpretation that immunosuppressive antilymphocytic antibodies had been removed from ALS by absorption with SRBC.
Reply to Kargar and Aazami (2006)

We thank Kargar and Aazami [1] for their interest in our recent article on flow dynamics and wall shear stress (WSS) in the left internal thoracic artery (LITA) [2]. In this study we show that the LITA has a marked adaptability to flow dynamics with a clear propension to adequate WSS and crosssectional area to flow requirements. Two modifications take place into proximal LITA used as a composite Y-graft: (1) a ‘passive’ increase in blood flow due to the lower resistance of the parallel vascular circuit represented by the Y-graft, as expressed by the Kirchoff’s 2nd law, and (2) an ‘active’ increase of proximal LITA diameter related to the higher average peak velocity and blood flow that stimulate the synthetic and secretory functions of endothelial cells, modulating the production of nitric oxide and endothelin-1 to obtain proximal LITA dilatation. Finally also the flow pattern could have a role in the production of vasoactive substances by vascular endothelial cells, presenting the proximal part of LITAY-graft a diastolic-predominant peak of flow velocity, probably related to the reduced vascular resistance of the parallel vascular circuit. In conclusion our study shows that in composite Y-graft the proximal LITA is able to actively adapt its dimension to the flow demand, probably through the release of endothelial vasoactive mediators, consequence of higher values of WSS. This process of adaptation begins immediately after the operation because of the passive increase of blood flow due to the lower vascular resistance of the Y-graft system. Kargar and Aazami seem to be skeptical about the adaptability of the LITA to increased myocardial blood flow requirements. However we have shown that soon after the operation the LITA used as a Y-graft can significantly increase blood flow in response to conditions of increased MVO2, keeping normal the O2 supply-to-demand ratio. We obtained these data measuring blood flow in Y-graft both at rest and during atrial pacing at the 85% of the patient age-predicted maximum, considering the heart rate-systolic blood pressure product an indirect index of MVO2 [3]. Both the afore mentioned functional data and the favourable clinical results coming from LITA used as a Y-graft [4] should comfort Kargar and Azami about the safety and afficacy of the LITA in Y-graft configuration. We thank again Kargar and Aazami for their interest in our paper.
A mucosal vaccine against Chlamydia trachomatis generates two waves of protective memory T cells (2015)

Genital Chlamydia trachomatis (Ct) infection induces protective immunity that depends on interferon-γ-producing CD4 T cells. By contrast, we report that mucosal exposure to ultraviolet light (UV)-inactivated Ct (UV-Ct) generated regulatory T cells that exacerbated subsequent Ct infection. We show that mucosal immunization with UV-Ct complexed with charge-switching synthetic adjuvant particles (cSAPs) elicited long-lived protection in conventional and humanized mice. UV-Ct-cSAP targeted immunogenic uterine CD11b(+)CD103(-) dendritic cells (DCs), whereas UV-Ct accumulated in tolerogenic CD11b(-)CD103(+) DCs. Regardless of vaccination route, UV-Ct-cSAP induced systemic memory T cells, but only mucosal vaccination induced effector T cells that rapidly seeded uterine mucosa with resident memory T cells (T(RM) cells). Optimal Ct clearance required both T(RM) seeding and subsequent infection-induced recruitment of circulating memory T cells. Thus, UV-Ct-cSAP vaccination generated two synergistic memory T cell subsets with distinct migratory properties.
Breath biomarkers in environmental health science: exploring patterns in the human exposome (2011)

The human genome is the counterpart to the human exposome with respect to the gene × environment interaction that describes health state and outcome. The genome has already been sequenced and is in the process of being assessed for specific functionality; to similarly decode the exposome will require the measurement and interpretation of suites of biomarker compounds in biological media such as blood, breath and urine. Of these, exhaled breath provides some important advantages for community or population-based studies in that the supply is essentially unlimited, the sampling procedures are non-invasive and can be self-administered, and there are little, if any, infectious wastes generated. The main concerns are to document a variety of compounds in breath, to assess what compounds and concentrations are considered statistically 'normal' in the healthy or unremarkably exposed population, and what graphic and mathematical approaches can be applied to assess outlier measurements as perturbations to the healthy exposome. In this paper, we explore a data set of exhaled breath measurements of exogenous exposures to jet fuel and develop summary statistics and variable clustering methods to establish between-group and intrinsic within-sample patterns that could be used to assess the status of random subjects.
