The statistics of directed evolution: From library generation to high throughput screens

Directed evolution has been recognized as a powerful approach to creating enzymes and cells with desirable properties, such as growth on a new substrate, thermotolerance, or even novel reaction mechanisms. The directed evolution approach is to generate diversity through genetic mutations and screen the diversity for mutants that have improved properties compared to the parent. This diversification and screening can be repeated to generate mutants with superior properties. While the concept is straightforward, the devil is in the details. How should I create diversity (error prone PCR, mutagenic primers, transposons…)? How much diversity do I need (103, 106, 107, more??). If my high throughput screen (HTS) does not find an improved mutant, does that mean an improved mutant did not exist in the library? Or could it mean my HTS failed to isolate it? How do I identify single cells with 20% improvement, when cell-to-cell variability is more than 10 fold larger? In this workshop, we will start to answer several of these questions. We will review approaches for generating and quantifying diversity. We will develop a Bayesian framework for understanding noise due to cell-to-cell variability and be able to predict the expected enrichment achievable in fluorescence-activated cell sorting (FACS) and other HTS screens. We will discuss common pitfalls in generating libraries and screening them. If you do directed evolution on enzymes or cells, if you use FACS, droplet-based HTS, or even plate-based screening, this workshop will provide you with fundamental tools to add rigor to your directed evolution efforts and improve your likelihood of success

Statistical scene generation for polarimetric imaging systems

Little publicly available data exists for polarimetric measurements. When designing task specific polarimetric systems, the statistical properties of the task specific data becomes important. Until better polarimetric datasets are available to deduce statistics from, the statistics must be simulated to test instrument performance. Most imaged scenes have been shown to follow a power law power spectral density distribution, for both natural and city scenes. Furthermore, imaged data appears to follow a power law power spectral distribution temporally. We are interested in generating image sets which change over time, and at the same time are correlated between different components (spectral or polarimetric). In this brief communication, we present a framework and provide code to generate such data.Comment: 5 pages, 3 figures, 3 matlab function

Multipurpose tenofovir disoproxil fumarate electrospun fibers for the prevention of HIV-1 and HSV-2 infections.

Sexually transmitted infections affect hundreds of millions of worldwide. Both human immunodeficiency virus (HIV-1 and -2) and herpes simplex virus-2 (HSV-2) remain incurable, urging the development of new prevention strategies. While current prophylactic technologies are dependent on strict user adherence to achieve efficacy, there is a dearth of delivery vehicles that provide discreet and convenient administration, combined with prolonged-delivery of active agents. To address these needs, we created electrospun fibers (EFs) comprised of FDA-approved polymers, poly(lactic-co-glycolic acid) (PLGA) and poly(DL-lactide-co-ε-caprolactone) (PLCL), to provide sustained-release and in vitro protection against HIV-1 and HSV-2. PLGA and PLCL EFs, incorporating the antiretroviral, tenofovir disoproxil fumarate (TDF), exhibited sustained-release for up to 4 weeks, and provided complete in vitro protection against HSV-2 and HIV-1 for 24 hr and 2 wk, respectively. In vitro tests confirmed the safety of these fibers in vaginal and cervical cells, highlighting the potential of polymeric EFs as multipurpose next-generation drug delivery vehicles

Empirical Analysis and Automated Classification of Security Bug Reports

With the ever expanding amount of sensitive data being placed into computer systems, the need for effective cybersecurity is of utmost importance. However, there is a shortage of detailed empirical studies of security vulnerabilities from which cybersecurity metrics and best practices could be determined. This thesis has two main research goals: (1) to explore the distribution and characteristics of security vulnerabilities based on the information provided in bug tracking systems and (2) to develop data analytics approaches for automatic classification of bug reports as security or non-security related. This work is based on using three NASA datasets as case studies. The empirical analysis showed that the majority of software vulnerabilities belong only to a small number of types. Addressing these types of vulnerabilities will consequently lead to cost efficient improvement of software security. Since this analysis requires labeling of each bug report in the bug tracking system, we explored using machine learning to automate the classification of each bug report as a security or non-security related (two-class classification), as well as each security related bug report as specific security type (multiclass classification). In addition to using supervised machine learning algorithms, a novel unsupervised machine learning approach is proposed. Of the machine learning algorithms tested, Naive Bayes was the most consistent, well performing classifier across all datasets. The novel unsupervised approach did not perform as well as the supervised methods, but still performed well resulting in a G-Score of 0.715 in the case of best performance whereas the supervised approach achieved a G-Score of 0.903 in the case of best performance

Electrospun fibers and nanoparticles for the prevention of sexually transmitted infections.

Human immunodeficiency virus-1 (HIV-1) and herpes simplex virus 2 (HSV-2) affect hundreds of millions of people worldwide, with women disproportionately impacted by these infections. Currently, only oral pre-exposure prophylaxis (PrEP) is approved specifically for the prevention of HIV-1, but is challenged with adverse side effects associated with long-term use. Topical delivery platforms, such as gels and films, deliver agents directly to the female reproductive tract, but are limited in providing transient-release. The technology of polymeric electrospun fibers may serve as alternative topical delivery platform to the female reproductive tract. In these studies, we fabricated electrospun fibers comprised of different polymers or polymer blends that possess different physical attributes and fiber architectures. The goal was to provide sustained-release of agents such as the antiretroviral tenofovir disoproxil fumarate (TDF) and the antiviral lectin, Griffithsin (GRFT). We hypothesized that these delivery platforms would prevent HIV-1 and HSV-2 infections, while retaining the safety and biocompatibility of free agent. To determine the amount of GRFT loading and release from fiber formulations, ELISA was conducted, whereas TDF quantification was performed using absorbance measurements. Next, the in vitro efficacy of composites was assessed in HIV-1 and HSV-2 infectivity assays. From these initial results, multilayered fiber composites, free NPs, and hydrophilic fibers were tested for safety and antiviral efficacy within a murine model. Animal studies were conducted using 5-week-old female BALB/c mice, histology and cytokine expression were evaluated from mouse reproductive tracts and vaginal lavages collected 24 and 72 hr following platform administration. In parallel experiments, mice were administered fibers, followed by a single challenge 4 or 24 hr later with HSV-2 (LD90). Viral progression was monitored for 14 days post viral challenge to evaluate potential infection. Statistical significance for all studies was determined using one-way ANOVA with Bonferroni post hoc test (p \u3c 0.05), while log-ranked post hoc tests were used for antiviral efficacy studies. Future studies will consider encapsulation of multiple antiviral compounds to provide synergetic protection against infection

The Effect of Body Mass Index on Pedometer Accuracy in a Free-Living Environment

The purpose of this dissertation was to determine if the New Lifestyles NL-2000 (NL) and the Digi-Walker SW-200 (DW), waist-mounted devices, yield similar daily step counts as compared to the StepWatch 3 (SW), an ankle-mounted device, worn by adults and children in the free-living environment. For the first study, fifty-six adults (32.7 + 14.5 y) wore the devices for seven consecutive days. There were 20 normal weight, 18 overweight, and 18 obese participants. The NL and DW undercounted (pedometer error) similarly in the normal weight and overweight groups (-15.4% to -18.2%, respectively). However, the DW undercounted more than the NL in the obese group (-32.8% vs -23.9%, respectively). Stepwise regression revealed that both the NL and DW had more error (undercounted more) as a greater percentage steps were accumulated while walking slowly. The DW also had more error with greater BMI. Use of the DW in an obese population will result in twice the error as compared to a normal weight population and thus the DW should not be used to determine relationships between walking volume and adiposity For the second study, 74 children (13 ± 1.1 y) wore the same devices during one weekday. There were 33 normal weight, 21 overweight, and 20 obese participants. The error was determined for the NL and DW, and the values were similar in the normal weight and overweight groups (-10.8% to -15.4%, respectively). The DW undercounted more than the NL in the obese group (-27.3% vs -8.4%, respectively). The NL was very consistent regardless of BMI category, recording 89.1% (-10.8% error), 89.1% (-10.9% error), and 91.6% (-8.4% error) for the normal weight, overweight, and obese participants, respectively. Stepwise regression revealed that the DW undercounted more in participants with a high weight. Using the DW in obese children of this age group will result in significantly more undercounting when compared to normal weight children. The DW should not be used to determine relationships between walking volume and adiposity in this population. The NL undercounted by ~10%, regardless of BMI category

Design and Implementation of A Led Dot Matrix Display

Information passage and sharing is very vital in the world of communication. In recent years there have been a call to modernize the information  passage processes and going by the human aesthetics taste for colorful and beautiful things and environments, there is a need, therefore, to introduce  aesthetics into the way information are displayed on billboard especially in a dark environment which characterizes Sub-Saharan Africa. In this paper,  therefore, the design and implementation of moving message display based on microcontroller was carried out. The display units which comprise  transformers, ATMEGA microcontroller, Filtration unit, uses Light Emitting Diodes LED in a 7 × 60 arrangement to form the predetermined characters, which lights up progressively as an effect. Once the message is completely displayed, it latches for a proposed time and abruptly disappears and the  process is repeated over again with the scrolling of characters
