Alternative antimicrobial compounds to control potential Lactobacillus contamination in bioethanol fermentations

Antibiotics are commonly used to control microbial contaminants in yeast-based bioethanol fermentation. Given the increase in antibiotic-resistant bacteria, alternative natural antimicrobials were evaluated against the potential contaminant, Lactobacillus. The effects of nisin, ϵ-polylysine, chitosan (CS) and lysozyme were screened against 5 Lactobacillus strains. A standard broth- microdilution method was used in 96-well plates to assess the minimal inhibitory concentration (MIC). L. delbrueckii subsp lactis ATCC479 exhibited maximal MICs with CS, ϵ-polylysine and nisin (1.87, 0.3125 and 0.05 mg/mL, respectively). Nisin reduced most Lactobacillus strains by 6 log CFU/mL after 48 hours with the exception of L. casei. Synergism occurred when ethylenediaminetetraacetic acid (EDTA) was added with nisin. An MIC of 0.4 mg/mL of nisin combined with the EDTA at an MIC of 1 mg/ml markedly suppressed L . casei by 6 log CFU/mL. In conclusion, alternative antimicrobials proved to be a potential candidate for controlling bacterial contamination in the fermentation process. Synergistic effect of nisin with EDTA successfully inhibited the nisin-resistant contaminant, L. casei.
PDR and LRMAP detection tests applied to massive hyperspectral data

Recent works showed that two composite detection tests based on Maximum A Posteriori (MAP) estimates can be more powerful than the Generalized Likelihood Ratio (GLR) in the case of sparse parameters. These tests are the Posterior Density Ratio (PDR), which computes the ratio of the a posteriori distribution under each hypothesis, and the LRMAP, where the MAP replaces the Maximum Likelihood estimate. We propose here a compared analysis of the two MAP-based tests performances. The implementation details of these tests are then analyzed in the framework of massive hyperspectral data which will be acquired by the MUSE (Multi Unit Spectroscopic Explorer) integral field spectrograph. We finally improve the detection strategy proposed in [8] by better exploiting the spatial dependencies existing in the data cube.
Report on the INEX 2004 interactive track

As scientific data repositories, digital libraries and publishers increasingly use the eXtensible Markup Language (XML) for publication and storage interest has arisen in exploiting this formatting for retrieval purposes. XML is attractive because it defines the logical structure of the documents and has the potential to assist IR systems in providing more appropriate results to users, i.e., to return relevant document components (i.e. XML elements) rather than whole documents. In addition, the XML tags often have specific semantics that may be exploited purposefully in IR.
Assessment of Psychotic Risk in a Sample of Children and Adolescents with Autism Spectrum Disorder Compared to a Group of “Clinical High Risk” Patients: A Preliminary Study

1. Background: Autism spectrum disorder and psychotic risk show several overlapping symptoms, so differential diagnosis is often difficult. In addition, there is a high rate of comorbidity between the two conditions, which further complicates the work of clinicians. We evaluated the presence of subthreshold psychotic symptoms and/or defined psychotic risk syndromes in autistic children and adolescents; we compared the prevalence, type, and severity of psychotic risk symptoms with those of a group of non-autistic patients at clinical high risk for psychosis (CHR-P). 2. Methods: In total, 23 autistic patients and 14 CHR-P patients without autism (aged 8–17) were enrolled in the study. The main assessment was made through clinical interviews for autism (Autism Diagnostic Observation Schedule, Second Edition—ADOS-2, Autism Diagnostic Interview, Revised—ADI-R) and psychotic risk (Schizophrenia Proneness Instrument, Child and Youth version—SPI-CY, Structured Interview for Psychosis Risk Syndromes—SIPS). 3. Results: No above-threshold psychotic risk symptoms were detected in our autistic patients, but subthreshold psychotic symptoms were identified in all areas. Specific items from all four dimensions of SIPS appear to be more specific for psychotic risk than autism without comorbidity. 4. Conclusions: An a priori screening of psychotic risk in neurodiverse populations is fundamental to prevent more severe conditions. Research should clarify the effective specificity of the available tools to modify them to improve their detection capability.
AT&T Research at TRECVID 2010

AT&T participated in two tasks at TRECVID 2010: contentbased copy detection (CCD) and instance-based search (INS). The CCD system developed for TRECVID 2009 was enhanced for eciency and scale and was augmented by audio features [1]. As a pilot task, participation in INS was meant to evaluate a number of algorithms traditionally used for search in a fully automated setting. In this paper, we report the enhancement of our CCD system and propose a system for INS that attempts to leverage retrieval techniques from dierent audio, video, and textual cues.
Sketching subdivision surfaces

We describe a 3D modeling system that combines subdivision surfaces with sketch-based modeling in order to meet two conflicting goals: ease of use and fine-grained shape control. For the excellent control, low-poly modeling is still the method of choice for creating high-quality 3D models, e.g., in the games industry. However, direct mesh editing can be very tedious and time consuming. Our idea is to include also stroke-based techniques for rapidly modeling regular surface parts. We propose a simple and efficient algorithm for converting a 2D stroke to a control polygon suitable for Catmull/Clark subdivision surfaces. We have realized a small but reasonably rich set of interactive modeling tools to assess the expressiveness of stroke-based mesh design with a number of examples.
Treatment of non-union in fractures of long bones.

Non-union of a long bone presents a formidable prospect to the patient. Eight months or more have, by d e f i n i t i ~ n , ~ elapsed since his injury and he is faced with a further period of prolonged treatment before he can return to a normal way of life. This series of 113 patients (one with 2 nonunions) was treated by rigid stabilization, where possible using compression by means of internal fixation. The principle of compression of a non-union to secure healing was described by Dank' in 1949. A series of 100 uninfected non-unions treated by rigid internal fixation was reported in 1966.4 The present series combines the further experience of one of the authors (Muller) with that of the resident staff of the Inselspital, Berne. It is the practice of Swiss Study Group Clinics to consider surgical intervention if a fracture shows evidence of delayed healing at 3-4 months and many cases of potential non-union are thus aborted. These cases are not included in this series, which is confined to long bones excluding non-unions of the femoral neck. The recorded results are
Involvement of Sex Steroid Hormones in the Early Stages of Spermatogenesis in Japanese Huchen (Hucho perryi )1

Abstract In higher vertebrates, considerable progress has been made in understanding the endocrine regulation of puberty; however, in teleosts, the regulatory mechanisms of spermatogenesis during the first annual cycle remain unclear. The present study was conducted to understand the regulatory mechanisms of spermatogenesis throughout the different stages of the first spermatogenic cycle and to check the ability of various steroids and hormones to induce in vitro spermatogonial proliferation in Japanese huchen (Hucho perryi ). The results indicate that the serum level of 11-ketotestosterone (11-KT) was positively associated with germ cell type; the level first began to rise with the appearance of late-type B spermatogonia and continued to increase gradually throughout the active spermatogenic stages and spermiogenesis, reaching a peak value 2 wk before spawning, and then declined. During the spermatogenic stages, the serum concentration of 17α,20β-dihydroxy-4-pregnen-3-one (17α,20β-DP) was undetectable. Only a small peak was detected with the appearance of spermatocytes and spermatids, and at the time of spawning, the level increased dramatically, reaching its maximum value with the onset of milt production. Despite the high variation in serum levels of 17β-estradiol (E2) both between months and among the individuals, E2 was found during the whole reproductive cycle. From these results, we concluded that 1) 11-KT is necessary for the initiation of spermatogenesis and sperm production, and it probably plays a role in spermiation, 2) 17α,20β-DP is essential for the final maturation stage, could play a significant role in the mitosis phase and meiosis process, and probably participates in the regulation of spawning behavior, and 3) estrogen is an indispensable male hormone that plays a physiological role in some aspects of testicular functions, especially during the mitotic phase. The three steroids were also able to induce DNA synthesis, spermatogonial renewal, and/or spermatogonial proliferation in vitro.
A satellite remote-sensing multi-index approach to discriminate pelagic Sargassum in the waters of the Yucatan Peninsula, Mexico

ABSTRACT Recently, the need for quantitative information on the spatiotemporal distribution of floating macroalgae, particularly the two species of genus Sargassum, has grown because of blooms of these species in the Gulf of Mexico and Caribbean Sea. Remote sensing is one of the most frequently used tools to assess pelagic Sargassum distribution. The purpose of this study was to implement a methodological approach to detect floating algae in an efficient and replicable manner at a moderate cost. We analyzed Landsat 8 imagery, from which we calculated four vegetation indices and one floating-algae index to implement a supervised classification, together with the bands 2 and 5, using the Random Forest algorithm. The analysis was performed monthly from 2014 to 2015 for the northeastern Yucatan Peninsula, Mexico, with a total of 91 analyzed images. The quantitative performance metrics of the classifier (overall, Kappa and Tau) were greater than 80%, whereas bands 2 and 5 as well as the atmospherically resistant vegetation index made the greatest contributions to the classifications. During summer 2015, more than 4,000 ha of Sargassum coverage per image were observed, which was substantially greater than that over the rest of the period. This approach constitutes a transferable alternative for the systematic detection of Sargassum, which enables a quantitative semi-automated time series comparison.
Exercise‐induced hyperkalaemia can be reduced in human subjects by moderate training without change in skeletal muscle Na, K‐ATPase concentration

Abstract. In 15 conscripts, venous plasma potassium was followed during exercise on a training bicycle before and after 10 weeks of moderate physical training and a putative relationship with skeletal muscle Na, K‐ATPase was evaluated. Peak plasma potassium concentration obtained at exhaustion was 61 pM 0.2 and 5.6 pM 0.2 mmol l‐1 (mean pM SEM, n= 14, P < 0.05) before and after training, respectively. Throughout the exercise period and within the first minutes of rest plasma potassium concentration was 0.2–0.5 mmol l‐1 higher before than after training. Neither peak values nor peak rises in plasma potassium concentration before nor after training were correlated to the 3H‐ouabain binding site (Na, K‐ATPase) concentration in vastus lateralis muscle. The results indicate that net loss of potassium from the skeletal muscle pool during exercise is reduced after training, that the heart during exercise may be exposed to a smaller rise in plasma potassium concentration after training than before, and that moderate improvement of capacity to clear extracellular potassium during exercise may be due to increased activity of existing Na, K‐pumps in resting skeletal muscle fibres. This may reduce muscle fatigue, increase physical performance and explain the paradoxical observation that, despite an increased catecholamine response, there is a reduced risk of cardiac events after training.
Formation and growth of silicon nitride particles in a laser-driven aerosol reactor investigated with photon correlation spectroscopy and electron microscopy

ABSTRACT This paper investigates the formation and growth of silicon nitride particles in a laser-driven aerosol reactor. This investigation is done on-line with photon correlation spectroscopy (PCS) and off-line with electron microscopy. The results of the measurements are compared with each other and with a monodisperse growth model that incorporates the influence of particle shape. PCS proved to be a good and fast monitoring technique, but it provides limited information: the intensity-weighted average particle size and approximate velocity. Electron microscope studies of samples showed good agreement with both the spectroscopy and the modeling results. The incorporation in the model and in the determination of the PCS diameter of the extra information about particle size and phase from the electron microscope photographs increases their accuracy. This is necessary if PCS combined with growth model are to be used for process control. Although the analysis techniques and the model are applied to a speci.
B-myc inhibits neoplastic transformation and transcriptional activation by c-myc

B-myc is a recently described myc gene whose product has not been functionally characterized. The predicted product of B-myc is a 168-amino-acid protein with extensive homology to the c-Myc amino-terminal region, previously shown to contain a transcriptional activation domain. We hypothesized that B-Myc might also function in transcriptional regulation, although its role in regulating gene expression is predicted to be unique, because B-Myc lacks the specific DNA-binding motif found in other Myc proteins. To determine whether B-Myc could interact with the transcriptional machinery, we studied the transcriptional activation properties of a chimeric protein containing B-Myc sequences fused to the DNA-binding domain of the yeast transcriptional activator GAL4 (GAL4-B-Myc). We found that GAL4-B-Myc strongly activated expression of a GAL4-regulated reporter gene in mammalian cells. In addition, full-length B-Myc was able to inhibit or squelch reporter gene activation by a GAL4 chimeric protein containing the c-Myc transcriptional activation domain. We also observed that B-Myc dramatically inhibited the neoplastic cotransforming activity of c-Myc and activated Ras in rat embryo cells. Because B-Myc inhibits both neoplastic transformation and transcriptional activation by c-Myc, we suggest that the transforming activity of c-Myc is related to its ability to regulate transcription. Whether B-Myc functions biologically to squelch transcription and/or to regulate transcription through a specific DNA-binding protein remains unestablished.

ENHANCEMENT OF SECURITY FEATURE IN GRAPHICAL PASSWORD AUTHENTICATION

The notion of the paper is to provide an efficient and secure graphical password system with the use of colour images. The images will be the base for the password scheme for the users. The two main features of graphical passwords are usability and security while designing any graphical approach. Hence we need to maintain a balance between both the features. On the basis of the study of the previous algorithms we have analyzed the security features of the algorithms, we added the concept of graining (adding noise to the image) and processed the image using variation in the RGB colour scheme of the image along with rotation and resizing scheme used earlier[1]. Here the images will be concatenated along with the text to enhance the security feature of the approach and this concatenation of the text will serve against shoulder surfing attack.
A Configurable Motion Estimation Architecture for Block-Matching Algorithms

This paper introduces a configurable motion estimation architecture for a wide range of fast block-matching algorithms (BMAs). Contemporary motion estimation architectures are either too rigid for multiple BMAs or the flexibility in them is implemented at the cost of reduced performance. The proposed architecture overcomes both of these limitations. The configurability of the proposed architecture is based on a new BMA framework that can be adjusted to support the desired set of BMAs. The chosen framework configuration is implemented by an intelligent control logic which is integrated to an efficient parallel memory system and distortion computation unit. The flexibility of the framework is demonstrated by mapping five different BMAs (BBGDS, DS, CDS, HEXBS, and TSS) to the architecture. The total execution time of the mapped BMAs is shown to be almost directly proportional to the number of tested checking points in the search area, so the architecture is very tolerant of different BMA-specific search strategies and search patterns. In addition, a run-time switching between supported BMAs can be done without performance compromises. With a 0.13-mum CMOS technology, the proposed architecture configured for HEXBS, BBGDS, and TSS requires only 14.2 kgates and 2.5 KB of memory at 200 MHz operating frequency. A performance comparison to the reference programmable architectures reveals that only the proposed implementation is able to process real-time (30 fps) fixed block-size motion estimation (1 reference frame) at full HDTV resolution (1920 times1080).
Effectiveness of Alternative Methods for Toothbrush Disinfection: An In Vitro Study

Objective. This study aimed to evaluate the effectiveness of alternative methods for toothbrush disinfection. Methods. Two-hundred eighty toothbrushes were included in the study. The toothbrushes were divided into 7 groups and were contaminated by standardized suspensions of Lactobacillus rhamnosus (L. rhamnosus), Streptococcus mutans (S. mutans), Staphylococcus aureus (S. aureus), and Escherichia coli (E. coli). The following disinfectants were tested: 1% sodium hypochlorite (NaOCl), 100% and 50% white vinegar, microwave (MW) oven, ultraviolet (UV) sanitizer, and mouth rinse-containing propolis (MCP). Data were analyzed with Kruskal Wallis and Dunn's tests. Results. Statistically significant differences were found between different methods and control group for all tested bacteria. There were statistically significant differences between all test groups for all microorganisms. MW was the most effective for L. rhamnosus and 100% white vinegar was the most effective method for S. mutans and S. aureus. NaOCl was the most effective for E. coli. Conclusion. This study showed that 100% white vinegar was considered to be effective for tested microorganisms. Similarly, 1% NaOCl is cost-effective, easily accessible, and comparatively effective for toothbrush disinfection. Because these agents are nontoxic, cost-effective and easily accessible, they may be appropriate for household use.
Approximate arguments for efficiency in logical argumentation

There are a number of frameworks for modelling argumentation in logic. They incorporate a formal representation of individual arguments and techniques for comparing conflicting arguments. A common assumption for logic-based argumentation is that an argument is a pair 〈Φ, α〉 where Φ is minimal subset of the knowledgebase such that Φ is consistent and Φ entails the claim α. Different logics are based on different definitions for entailment and consistency, and give us different options for argumentation. For a variety of logics, in particular for classical logic, the computational viability of generating arguments is an issue. Here, we propose ameliorating this problem by using approximate arguments.
Stabilization and georegistration of aerial video over mountain terrain by means of lidar

Stabilization and georegistration of aerial video are important problems that can be difficult to solve, especially over mountainous regions. We introduce an approach that registers video frames to images predicted from a digital elevation model derived from LIDAR. It does not require reference imagery, because three-dimensional features such as rocks and vegetation can be predicted and registered with the corresponding features in the video imagery. The algorithm recovers the exterior and interior camera orientations with accuracy, and it accomplishes stabilization, georegistration and orthorectification of the video. This enables many applications, including fusion with satellite imagery, overlay of map graphics, and detection of moving objects. After describing the algorithm, we present results on several motion imagery datasets, including infrared and color video, and several types of elevation data.
Integrated Path Following and Lateral Stability Control of Distributed Drive Autonomous Unmanned Vehicle

Intelligentization is the development trend of the future automobile industry. Intelligentization requires that the dynamic control of the vehicle can complete the trajectory tracking according to the trajectory output of the decision planning the driving state of the vehicle and ensure the driving safety and stability of the vehicle. However, trajectory limit planning and harsh road conditions caused by emergencies will increase the difficulty of trajectory tracking and stability control of unmanned vehicles. In view of the above problems, this paper studies the trajectory tracking and stability control of distributed drive unmanned vehicles. This paper applies a hierarchical control framework. Firstly, in the upper controller, an adaptive prediction time linear quadratic regulator (APT LQR) path following algorithm is proposed to acquire the desired front-wheel-steering angle considering the dynamic stability performance of the tires. The lateral stability of the DDAUV is determined based on the phase plane, and the sliding surface, in the improved sliding mode control (SMC), is further dynamically adjusted to obtain the desired additional yaw moment for coordinating the path following and lateral stability. Then, in the lower controller, considering the slip and the working load of four tires, a comprehensive cost function is established to reasonably distribute the driving torque of four in-wheel motors (IWMs) for producing the desired additional yaw moment. Finally, the proposed control algorithm is verified by the hardware-in-the-loop (HIL) experiment platform. The results show the path following and lateral stability can be coordinated effectively under different driving conditions.
