Bottleneck in the Drug Pipeline?
Alternative Tumor Measurement-based Phase II Clinical Trial Endpoints for Predicting Overall Survival

Ming-Wen An, Vassar College

In the final stages of a long and costly drug discovery process, a drug compound is introduced into humans as part of a clinical trial. A clinical trial is a research study with a pre-defined protocol and is conducted in different phases. In oncology, as many as 60% of drug compounds that reach the last phase (Phase III) fail this final step. This high failure rate may reflect inappropriate evaluation of compounds in preceding Phase II trials, in which the primary endpoint is often binary tumor response, based on the Response Evaluation Criteria for Solid Tumors (RECIST). This motivates the search for alternative Phase II endpoints. In this talk, we will introduce clinical trials and survival analysis to contextualize the problem. Then we will describe our work evaluating alternative categorical and continuous tumor measurement-based endpoints for their ability to predict overall survival using data from real clinical trials.

Addicted to Rehab:
Race, Gender, and Drug Treatment in the Era of Mass Incarceration 

Allison McKimSociology Program

After decades of the American “war on drugs," relentless prison expansion, and rising opioid deaths, political officials are finally challenging mass incarceration. Many point to an apparently promising solution: addiction treatment. However, we know so little about what goes on inside treatment programs that scholars have called it a “black box.” Allison McKim’s ethnographic research heads inside the black box to compare two treatment programs for women – one in the criminal justice system and one in the healthcare system. There, she finds two different ways of defining and treating addiction. She reveals that the category "addiction" reflects punitive criminal justice policy and its race, class, and gender politics. Thus when we use "addiction" to understand and address complex social problems, we further stigmatize marginalized women, reproduce inequality, and extend punishment.

A Reading by Diane Ackerman

The celebrated author reads from The Zookeeper’s Wife

On Monday, October 30, at 2:30 p.m. in Weis Cinema, Bertelsmann Campus Center, Diane Ackerman reads from The Zookeeper’s Wife. Sponsored by the Innovative Contemporary Fiction Reading Series, introduced by Bradford Morrow and followed by a Q&A, the reading is free and open to the public; no tickets or reservations are required.

The Zookeeper’s Wife, a little known true story of WWII, enjoyed months as the New York Times #1 nonfiction bestseller, was the basis for the 2017 feature film of the same title, and received the Orion Book Award, which honored it as “a groundbreaking work of nonfiction, in which the human relationship to nature is explored in an absolutely original way through looking at the Holocaust. A few years ago, ‘nature’ writers were asking themselves, How can a book be at the same time a work of art, an act of conscientious objection to the destruction of the world, and an affirmation of hope and human decency? The Zookeeper’s Wife answers this question.”

Diane Ackerman’s other works of nonfiction include An Alchemy of Mind, a poetics of the brain based on the latest neuroscience; Deep Play, which considers play, creativity, and our need for transcendence; A Slender Thread, about her work as a crisis line counselor; The Rarest of the Rare and The Moon by Whale Light, in which she explores the plight and fascination of endangered animals; On Extended Wings, her memoir of flying; and her bestseller, A Natural History of the Senses. Her most recent book, The Human Age: The World Shaped by Us, a celebration of the natural world and human ingenuity, and an exploration of human-driven planetary change, received the P.E.N. Henry David Thoreau Award for Nature Writing.

Several of Ackerman's books have been Pulitzer Prize and National Book Circle Critics Award finalists. She also has the rare distinction of having a molecule named after her—dianeackerone— a pheromone in crocodilians. Her essays about nature and human nature have been appearing for decades in the New York Times, New Yorker, American Scholar, Smithsonian, National Geographic, and elsewhere.

Any supporter who donates $500 or more to Bard’s literary journal Conjunctions receives a BackPage Pass providing VIP access to any Fall 2017 or future event in the Innovative Contemporary Fiction Reading Series. Have lunch with a visiting author, attend a seminar on their work, and receive premium seating at their reading. Or you can give your BackPage Pass to a lover of literature on your gift list!

Birth and Death in the Milky Way

 

David Helfand, Columbia University

Over the past ten years, my colleagues and I have been using the Very Large Array radio telescope to construct by the far highest resolution survey yet made of our Galaxy at centimeter wavelengths. The images reveal thousands of Galactic radio emitters which mark the places of stellar birth in cold clouds of  gas and dust, and stellar death in the violent explosions of supernove. Combining this survey with data from other wavelengths, particularly the Spitzer Space Observatory's Infrared survey of the Galaxy provides a spectacular new multi-colored view of the Milky Way and reveals a number of unexpected surprises.

Digital Topology:
A Smooth Introduction

Nicholas A. ScovilleUrsinus College 

Digital images surround us. They are found in our computers, iPhones, televisions, and more. Because they are so integrated into our lives, there is a constant need to manipulate and investigate these images. Anything that one might want to do with a digital image will inevitably involve some kind of mathematics, whether it be linear algebra, geometry, or topology. In this talk, we will introduce not only the topology of digital images, but topology in general. We'll discuss some of the main ideas in topology and use them to figure out what topology would mean in a digital setting. Our newfound knowledge of digital topology will then allow us to dene a digital version of the Hopf fibration, a function between spheres of different dimensions which links together circles in a beautiful and profound way. This talk will be accessible to undergraduates.

Harlem and the Roots of Gentrification, 1965-2003

Brian Goldstein, Swarthmore College

In the last four decades of the twentieth century, Harlem, New York—America’s most famous neighborhood—transformed from the archetypal symbol of midcentury “urban crisis” to the most celebrated example of “urban renaissance” in the United States. Once a favored subject for sociologists studying profound poverty and physical decline, by the new millennium Harlem found itself increasingly the site of refurbished brownstones, shiny glass and steel shopping centers, and a growing middle-class population. Drawing from Brian Goldstein’s new book, The Roots of Urban Renaissance: Gentrification and the Struggle Over Harlem (Harvard University Press, 2017), this lecture will trace this arc by focusing on competing visions for Harlem's central block. In doing so, it will reveal the complicated history of social and physical transformation that has changed this and many American urban centers in the last several decades. Gentrification is often described as a process controlled by outsiders, with clear winners and losers, victors and victims. In contrast, this talk will explore the role that Harlemites themselves played in bringing about Harlem’s urban renaissance, an outcome that had both positive and negative effects for their neighborhood.

      A lecture by
      Maria Belk
      Mathematics program
      Why are some structures rigid, but others fall down?  We'll look at some simple structure and examine their rigidity.  We'll start by considering bar frameworks - place the vertices of a graph in 2 or 3 dimensions, and think of the edges of the graph as bars, forced to maintain their length.  After examining the rigidity of bar frameworks, we'll move to consider tensegrities.  In a tensigrity framework, some of the edges are called struts and are allowed to increase in length while others are called cables and are allowed to decrease in length.  These are tensegrities where the struts are suspended in the air by the cables, and yet the entire structure is rigid.

      A lecture by
      Sven Anderson
      Computer Science program
      Telling the difference between human and automated programs such as Web-bots has become important in preventing Web-bot access to e-mail addresses, private information and limited electronic resources. CAPTCHAs, programs that can accurately judge whether a user is human or machine, are the primary line of defense against Web-bot access. For example, Google's Mail program uses CAPTHCAs to prevent Web-bots from creating bogus user accounts from which to launch spam messages. Every day humans solve about 60 million CAPTHCAs. The human "computation" expended has an unintended benefit: it can be recycled to help digitize old printed texts that are unrecognizable using optical character recognizers. This talk, intended for a general audience, will explore the vanishing difference between humans and computer programs on current text CAPTCHAs and outline efforts to keep one step ahead of the intelligent Web-bots. We will also consider other efforts to recycle human computation.

      A lecture by
      Lisa Scheifele
      candidate for the position in Biology
      Mobile DNA presents a considerable challenge to genome stability due to its presence as dispersed repeats.  Could this instability enable adaption and thereby explain why genomes retain high levels of mobile DNA?  Indeed, we have found that following experimental evolution, strains with higher levels of repetitive DNA contain a broader variation in chromosome structure.  The abundance of repetitive DNA must therefore be fine-tuned so that benefit of chromosome rearrangements in promoting genome evolution outweights the potential for lethal damage.

      A lecture by
      Keith O'Hara
      candidate for the position in Computer Science

      Just as special purpose mainframe computers grew into general purpose personal computers, special purpose industrial robots are evolving into general purpose personal robots.  Drawing on ideas from computer systems architecture such as parallelism, redundancy, heterogeneity, locality, and scaling laws, we propose a "robot systems architecture" perspective on the design of robot computing systems.  From this perspective, two distributed robot systems built for tasks as varied as computing education and mobile robot navigation will be presented.

      A lecture by Jane Liu,  candidate for the open position in Chemistry.

      Due to their central role in regulating bacterial pathogenesis, small non-coding RNAs (sRNAs) represent targets with therapeutic potential.  To investigate the entire repertoire of sRNAs in the human pathogen, Vibrio cholerae, we developed a method, sRNA-Seq, to directly clone and analyze whole populations of V. cholerae transcripts, 14 to 200 nucleotides, by high-throughput pyrosequencing.  From over 680,000 reads, 500 new intergenic sRNAs and 127 antisense sRNAs were identified.

      If you draw a grid on the plane and then zoom out, the empty squares between the gridlines become smaller and smaller until they are lost to sight.  The result is that the large-scale geometry of the plane is essentially the same as the large-scale geometry of an infinite grid.  In the same way, many non-Euclidean geometries can be understood on a large scale using infinite graphs.  In this talk, we will explore the geometry of several graphs that arise in this fashion, and we will discuss the sorts of questions that one might ask about the geometry of an infinite graph.


      Biology search candidate lecture - "Npl3: At the Interface of Transcription and mRNA processing"

      November 20
      Reem-Kayden Center Laszlo Z. Bito '60 Auditorium

      A lecture by Tracy Kress, candidate for the position in Biology.

      From the beginning of transcription, mRNAs are processed in a myriad of ways to specify the correct timing, localization, and quantity of protein synthesized. To ensure the efficiency and accuracy of gene expression, transcription and mRNA processing steps are tightly coordinated both spatially and temporally. Despite their critical importance, few factors that regulate this coordination are known. I identified Npl3 as one such factor, and my work aims to uncover the mechanism of Npl3, and other factors, in this coordination.

      Biology seminar - "The zebrafish as a model for heart disease"

      November 20
      Reem-Kayden Center Laszlo Z. Bito '60 Auditorium

      A lecture by Patrick Page-McCaw, Rensselaer Polytechnic Institute

      I will present two stories on how the zebrafish can be used as a model of heart disease.  In the first story, our lab has used genetic, pharmacological and surgical tools to dissect the affect of stress on cardiac output.  In the second story, we have discovered that Serum Amyloid A is required for cholesterol transport early in embryogenesis and that the failure to transport cholesterol results in defects in Hedgehog signaling.


      Chemistry search candidate lecture - "Electrostatics and Ribonuclease Biology"

      November 17
      Reem-Kayden Center Laszlo Z. Bito '60 Auditorium

      A lecture by Jeremy Johnson, candidate for the open position in Chemistry

      The mechanism of ribonuclease toxicity toward cancerous cells involves multiple steps, including cellular uptake and evasion of the ribonuclease inhibitor protein. Both of these steps of ribonuclease cytotoxicity are proposed to be controlled by the cationic nature of the ribonuclease and its interactions with the anionic cell membrane and anionic inhibitor. To understand the role that electrostatics play in ribonuclease biology, I investigated the effect that the positive charge of ribonuclease have on their cytotoxicity.

      Biology search candidate lecture - "Small non-coding RNAs in the bacterium Shewanella oneidensis: Computational prediction and experimental validation"

      November 13
      Reem-Kayden Center Laszlo Z. Bito '60 Auditorium

      A lecture by Brett Pellock, candidate for the open position in Biology.

      Bacteria use small, non-coding RNAs (ncRNAs) to rapidly alter gene expression in response to changing conditions. Bacterial ncRNAs are small and difficult to identify experimentally. We are synthesizing computational and experimental methods to predict and validate the existence of ncRNAs in Shewanella oneidensis, a bacterium that can reduce a wide variety of substrates when grown anaerobically. Of particular interest is the ability of Shewanella to reduce soluble, toxic heavy metals to insoluble, much less toxic forms.



      Biology seminar - "A Visual Narrative about Fruit Flies"

      November 13
      Reem-Kayden Center Laszlo Z. Bito '60 Auditorium

      A lecture by Alexis Gambis, The Rockefeller University

      Alexis Gambis will speak about the importance of visual imagery and narrative in both science understanding and communication. He will give insight into his current thesis work explaining the mechanisms of cellular death, how to use the fruit fly as a genetic model to study human neurodegenerative diseases, and the fluorescent toolkit to visualize neurons in the fruit fly eye . Using the camera eye, Alexis has also been actively making films with scientific themes during his graduate career. Alexis will talk about his recent films and the importance of visual storytelling in science communication, show a few clips of his film "A Fruit Fly in New York", and share his recent experience pioneering the first science film festival in New York.


      Science on the Edge lecture-"New Insights into the Chemistry of Depression"

      November 12
      Reem-Kayden Center Laszlo Z. Bito '60 Auditorium

      A lecture by Richard A. Gordon, Professor of Psychology.

      After the discovery of antidepressant drugs in the 1950s and the burst of research on neurotransmitters that took place in the 1960s, a scientific hypothesis about depression became firmly established in the community of researchers and clinicians: depression was rooted in depleted brain amines, such as norepinephrine and serotonin, a deficit that the antidepressants corrected. The amine hypothesis (known popularly and in pharmaceutical advertising as “chemical imbalance”) guided research throughout the rest of the 20th century. However, by the late 1990s it had become clear that direct research on the metabolism of depressed patients had failed to support the hypothesis. In this lecture I will discuss some exciting recent research that uses sophisticated techniques of brain imaging and has lent new support to the possibility that depleted amines are importantly involved in the chemistry of depression. Further commentary will be offered on the limitations and promise of this work, as well as some of the current thinking on the underpinnings of depression in the brain.

      Chemistry search candidate lecture - "Understanding Nucleic Acid Structure and its Interactions with Small Molecules"

      November 12
      Reem-Kayden Center Laszlo Z. Bito '60 Auditorium

      A lecture by Swapan Jain, candidate for the open position in Chemistry.

      According to RNA World hypothesis, early life used RNA for information storage and chemical catalysis. Small molecules may have played an important role in this endeavor by assembling nucleic acids during prebiotic evolution. Our results with proflavine and coralyne (small organic ligands) show that reactions carried out by protein enzymes today could have been achieved by non-enzymatic means. Mechanistic studies using hydroxyl radical footprinting have also been instrumental in our understanding of RNA structure. Future work aims to understand the structural changes that occur in riboswitches (noncoding region of mRNA) upon ligand binding. I would also like to investigate whether RNA can be regulated simultaneously by multiple pathways.

      Math seminar - "Reflexive Polytopes, Comples Tori, and Elliptic Curves"

      November 6
      RKC 111

      A lecture by Charles Doran, University of Alberta.

      We'll start by investigating the combinatorial properties of certain lattice polytopes in R^n, specifically reflexive polygons. By reinterpreting these as Newton polygons, we will relate these combintorial objects to algebraic equations naturally defined on complex tori. The vanishing loci of these equations are then elliptic curves, whose basic geometric and topological properties we will discuss. If time permits, we may also describe an application to string theory.

      Biology search candidate lecture - "Bacterial surface binding: Sweet attachments"

      November 6
      Reem-Kayden Center Laszlo Z. Bito '60 Auditorium

      A lecture by Brooke A. Jude, candidate for the open position in Biology.

      Investigation into Vibrio cholerae revealed that this organism colonizes both chitinous aquatic surfaces and the human small intestine via GbpA. Sequence analysis has revealed a GbpA homolog in all other Vibrio species that have been sequenced to date. We hypothesize that other aquatic Vibrio, such as Vibrio fluvialis, Vibrio vulnificus, or Vibrio parahemolyticus may also utilize GbpA to bind to environmental and intestinal surfaces. Current investigations include screening of aquatic isolates for attachment potential via GbpA.

      Computer science lecture - "Creating Realistic Graphical Agent Populations: An Integrated Artificial Intelligence (AI) Challenge"

      October 27
      Reem-Kayden Center Laszlo Z. Bito '60 Auditorium

      A lecture by Peter G. Selfridge, Ph.D.

      Virtual graphical environments (think Second Life or World Of Warcraft) have a number of real-world applications including training first responders, urban planning, and military training. Technology for creating both “geo-typical” terrain (e.g., a generic small city) and “geo-specific” terrain (e.g., downtown Kingston) has improved dramatically in recent years. What is missing is the ability to create realistic populations of regular people to populate the landscape: people commuting, going to lunch, taking their kids to daycare, et cetera.

      This talk will first review some motivating applications, the current state-of-the-art in terrain generation, and the general problem. Approaches to creating realistic agent populations will be reviewed, including crowd modeling, game technologies, and work in AI-style cognitive architectures. Two key challenges will then be described: the creation and maintenance of realistic behaviors, and the idea of scalable cognition or cognition on demand. Some research ideas to address these challenges will be briefly sketched.

      Bio:
      Peter Selfridge received his Ph.D. in Artificial Intelligence at the University of Rochester and spent 19 years at Bell Labs and then AT&T Bell Labs doing research into sensory robotics, artificial intelligence, knowledge representation, software visualization, interactive database exploration, 3D web technologies, and more. For the last 5 years he has supported the Defense Advanced Research Projects Agency (DARPA) in their mission of funding revolutionary R&D to help maintain the technological superiority of the United States. He also does independent research in Artificial Intelligence.



      Science on the Edge lecture-"The LHC: Testing the Standard Model and Beyond"

      October 21
      Reem-Kayden Center Laszlo Z. Bito '60 Auditorium

      A lecture by Matthew Deady, Physics program
      The Large Hadron Collider at the CERN laboratory in Switzerland has just been turned on for initial testing. The "Standard Model" of particles and fields has successfully matched theory and experiment for more than 30 years, and results from the LHC will put the model to its most stringent tests yet. The large energies available will also undoubtedly answer questions about extensions of and alternatives to the Standard Model, including supersymmetry, dark matter, dark energy, and string theory. In this lecture, these theories and what might be learned about them from the LHC will be explored. We will also discuss the spurious concerns that the LHC might cause a black hole that would swallow the universe.

      This talk will focus on the theories of particles, as a complement to the October 2007 talk which focused on the accelerator technology itself. An edited version of that talk appears in the latest issue of the Bardian.

      Math seminar - "The Mathematics of Fairness"

      October 16
      RKC 111

      Lecture by Allison Pacelli, Williams College.

      How do you divide a candy bar fairly between two people? The most popular solution is known by many and can even be found in the bible: one person divides the bar in half, the other gets to choose which piece she wants. But what happens if three people are dividing the candy? Worse yet, what do you do if you're dividing a collection of indivisible goods? Things like TV's and pianos are not much use cut in half! The idea of fairness itself is considerably more complicated when more than two people are involved, but mathematics can be surprisingly useful in these situations.

      Biology Seminar - "Invasion Ecology and Metacommunity Dynamics"

      October 16
      Reem-Kayden Center Laszlo Z. Bito '60 Auditorium

      A lecture by Martha F. Hoopes, Mount Holyoke College

      Early metacommunity theory emphasized four distinct models to explain the spatial structure, dynamics, and species composition of communities: species sorting, patch dynamics, mass effects, and the neutral model. Several tests of metacommunity theory have focused on these models and on determining their relative importance in explaining spatial community structure. Applying metacommunity theory to invasion ecology redirects the focus to examine how theory on spatial community dynamics can inform our understanding of spatial interactions when all species are not considered equal. This talk examines how a focal species approach affects the interpretation of processes critical to metacommunity dynamics. I offer some preliminary thoughts on conceptual differences between the four conceptual metacommunity models and explore these with three invasion case studies.

      Math & Computer Science seminar-"Losing L'Hopital for Limits through Lazy Logic"

      October 2
      RKC 111

      A lecture by Robert McGrail, Computer Science program.

      L'Hopital's Rule is a useful tool for computing limits with indeterminate forms. In fact, it is too useful. The speaker demonstrates how some of these limits can be computed without this rule. This talk is a shamless ruse designed to introduce the 0-1 law of finite mondel theory as well as expose the unwitting members of the audience to some very beautiful mathematics.



      Math & Computer Science lecture-"Calculus, Supersized"

      September 25
      RKC 111

      A lecture by Gregory Landweber, Mathematics program.
      In calculus, we teach you how to take derivatives, and then once you're good at that, we tell you about second derivatives. But how do we go in the other direction and try to take HALF a derivative? It turns out that to take a half derivative, your functions need to come in pairs, analogously to how a complex number can be thought of as a pair of numbers, one real and another imaginary. Supersymmetry is the study of such pairings. This talk will discuss different ways that supersymmetry arises, both through explicit constructions, and through the notion of superspace.
      **Some exposure to multivariable calculus and linear algebra will be assumed**

      Biology seminar-"Phenotypic plasticity as an adaptive host response to parasitic infection"

      September 25
      Reem-Kayden Center Laszlo Z. Bito '60 Auditorium

      A lecture by Dr. Lisa Schwanz, Cary Institute of Ecosystem Studies.

      Parasites negatively impact their host’s fitness, potentially damaging host tissues and impairing host physiological or behavioral performance. In response to parasitic infection, hosts may alter their physiology, behavior or life history in ways that minimize the costs of infection. In this talk, I examine the optimal life history response of hosts when infected with parasites that have varying impacts. In addition, I explore the impacts of schistosome infection in deer mice by examining host physiology, survival and reproductive investment. In accordance with predictions, deer mice infected with this parasite increase their investment in offspring.



      Science on the Edge lecture-"Finding the genes that make us human"

      September 24
      Reem-Kayden Center Laszlo Z. Bito '60 Auditorium

      A lecture by Michael Tibbetts, Biology program.
      What are the genetic bases of the qualities that we think of as uniquely human? Is there a set of “humaness” genes? Large-scale genome sequencing projects in multiple species are generating the kind of data that allow us, for the first time, to seriously ask such big questions. An article published in the September 5 issue of Science Magazine (Human-specific gain of function in a developmental enhancer, by Prabhakar, S. et al.) describes a gene whose human-specific activity may be necessary to form an opposable thumb. The nature of the differences between the human and chimpanzee versions of the gene they identify supports a popular model for how small modifications in genomes can lead to significant changes in physical characteristics. The methodologies employed by these researchers may lead to the discovery of genes important for other human-specific characteristics.
