Usability as a Method for Assessing Discovery
Authors: Ipri Tom , Yunkin Michael , Brown Jeanne M. 
Published: February 2013

The University of Nevada Las Vegas Libraries engaged in three projects that helped identify areas of its website that had inhibited discovery of services and resources. These projects also helped generate staff interest in the Usability Working Group, which led these endeavors. The first project studied student responses to the site. The second focused on a usability test with the Libraries’ peer research coaches and resulted in a presentation of those findings to the Libraries staff. The final project involved a specialized test, the results of which also were presented to staff. All three of these projects led to improvements to the website and will inform a larger redesign.

Enhancing OPAC Records for Discovery
Authors: Griffis Patrick 
Published: February 2013

This article proposes adding keywords and descriptors to the catalog records of electronic databases and media items to enhance their discovery. The authors contend that subject liaisons can add value to OPAC records and enhance discovery of electronic databases and media items by providing searchable keywords and resource descriptions. The authors provide an examination of OPAC records at their own library, which illustrates the disparity of useful keywords and descriptions within the notes field for media item records versus electronic database records. The authors outline methods for identifying useful keywords for indexing OPAC records of electronic databases. Also included is an analysis of the advantages of using Encore’s Community Tag and Community Review features to allow subject liaisons to work directly in the catalog instead of collaborating with cataloging staff
Tagging: An Organization Scheme for the Internet
Authors: Visser Marijke A. 
Published: February 2013

How should the information on the Internet be organized? This question and the possible solutions spark debates among people concerned with how we identify, classify, and retrieve Internet content. This paper discusses the benefits and the controversies of using a tagging system to organize Internet resources. Tagging refers to a classification system where individual Internet users apply labels, or tags, to digital resources. Tagging increased in popularity with the advent of Web 2.0 applications that encourage interaction among users. As more information is available digitally, the challenge to find an organizational system scalable to the Internet will continue to require forward thinking. Trained to ensure access to a range of informational resources, librarians need to be concerned with access to Internet content. Librarians can play a pivotal role by advocating for a system that supports the user at the moment of need. Tagging may just be the necessary system.

Authentication and Access: Accommodating Public Users in an Academic World
Authors: Weber Lynne , Lawrence Peg 
Published: February 2013

In the fall of 2004, the Academic Computing Center, a division of the Information Technology Services Department (ITS) at Minnesota State University, Mankato took over responsibility for the computers in the public areas of Memorial Library. For the first time, affiliated Memorial Library users were required to authenticate using a campus username and password, a change that effectively eliminated computer access for anyone not part of the university community. This posed a dilemma for the librarians. Because of its Federal Depository status, the library had a responsibility to provide general access to both print and online government publications for the general public. Furthermore, the library had a long tradition of providing guest access to most library resources, and there was reluctance to abandon the practice. Therefore the librarians worked with ITS to retain a small group of six computers that did not require authentication and were clearly marked for community use, along with several standup, open-access computers on each floor used primarily for searching the library catalog. The additional need to provide computer access to high school students visiting the library for research and instruction led to more discussions with ITS and resulted in a means of generating temporary usernames and passwords through a Web form. These user accommodations were implemented in the library without creating a written policy governing the use of open-access computers.
The Next Generation Library Catalog: A Comparative Study of the OPACs of Koha, Evergreen, and Voyager
Authors: Yang Sharon Q. , Hofmann Melissa A. 
Published: February 2013

Open source has been the center of attention in the library world for the past several years. Koha and Evergreen are the two major open-source integrated library systems (ILSs), and they continue to grow in maturity and popularity. The question remains as to how much we have achieved in open-source development toward the next-generation catalog compared to commercial systems. Little has been written in the library literature to answer this question. This paper intends to answer this question by comparing the next-generation features of the OPACs of two open-source ILSs (Koha and Evergreen) and one proprietary ILS (Voyager’s WebVoyage).

Dialectique de l’homogénéité et de la différence
Authors: Laflamme Simon 
Published: February 2013

Deux grandes visions s’affrontent au XXe siècle : l’une veut que les sociétés humaines évoluent en se diversifiant, l’autre maintient que ces sociétés tendent vers la similitude. Mais ces visions sont nourries beaucoup plus par l’observation sommaire et l’autoréflexion que par l’analyse empirique. Les travaux empiriques qui se penchent sur cette problématique inclinent à relever une évolution double. Dans cet article, nous faisons état du positionnement contradictoire des visions en sciences humaines, nous tentons de fournir une explication de la double tendance que mettent en relief les travaux empiriques en en dialectisant les éléments et nous reprenons quelques-uns de nos travaux qui témoignent par l’observation de cette dialectique.

Published: February 2013

AbstractThe objective of this study is to discuss the effective factors on morbidity and mortality in patients who were operated on for acute mesenteric ischemia. Between 2006 and 2011, 95 patients, who underwent emergent surgery for acute mesenteric ischemia, were analyzed retrospectively. The study group consisted of 56 men (58.9%) and 39 women (41.1%), with an average age of 68.4 ± 14.4 years. Elapsed time between the onset of the symptoms and the surgical operation was less than 24 hours in 47 (49.5%) cases, and more than 24 hours in 48 cases (50.5%) (P &lt; 0.001). Although all of the patients had intestinal necroses, colon involvement was seen in 38 patients, and mortality was higher in this group of patients (P &lt; 0.001). Mortality rate was 42.1%. This was higher in older patients, those with increased leukocyte levels, increased elapsed time to laparotomy, and when the colon was involved.

Abstract
A 62-year-old man was referred to our hospital because of pain in the right upper quadrant. Laboratory tests revealed normal levels of tumor markers. Abdominal ultrasonography showed a hypoechoic mass of approximately 9 cm in diameter in the right lobe of the liver. Computed tomography revealed a low-density mass with peripheral enhancement in the posterior segment of the right lobe. Magnetic resonance imaging showed a low-intensity mass on T1-weighted images and a high-intensity mass on T2-weighted images. Abdominal angiography showed enhanced staining only at the periphery of the tumor. An open biopsy was performed and intraoperative examination of frozen sections indicated malignant lymphoma. The histopathologic diagnosis was malignant T-cell lymphoma. After combined chemotherapy, the tumor shrank to 4 cm in diameter. To our knowledge, only 15 cases of malignant T-cell lymphoma have been reported previously. Diagnosis is particularly challenging because this type of tumor has no distinctive imaging characteristics or signs or symptoms. This case emphasizes the need to include malignant T-cell lymphoma in the differential diagnosis and demonstrates the importance of open biopsy in patients with a suspected liver tumor.
Effects of Natural and Recombinant Hirudin on VEGF Expression and Random Skin Flap Survival in a Venous Congested Rat Model
Authors: Yingxin Guo , Guoqian Yin , Jiaquan Li , Han Xiao 
Published: February 2013

Abstract
We aim to investigate the effects of locally injected natural and recombinant hirudin on vascular endothelial growth factor (VEGF) expression and flap survival in venous congested skin flaps using a rat model. A dorsal random skin flap (10 × 3 cm) was prepared on each of 30 Wistar rats to establish a venous congested model. The rats were randomly divided into 2 treatment groups [receiving subcutaneous injection of either natural hirudin (6 U) or recombinant hirudin (6 U)] and a control group, which received subcutaneous injection of physiologic saline. After treatment, skin flap survival rates were calculated. VEGF messenger RNA levels and VEGF-positive vessel density as a marker for VEGF levels were measured in the flaps during and after treatment. The skin flap VEGF messenger RNA levels increased in the natural hirudin-treated group. The VEGF-positive vessel density was increased in all 3 groups. Statistically significant increases of VEGF levels were observed in the natural and recombinant hirudin-treated groups compared with the control group (P &lt; 0.05). The skin flap survival rates were improved in both hirudin treated groups. Natural and recombinant hirudin can increase VEGF expression in random skin flaps, which can potentially improve random skin flap survival in rats through angio genic mechanisms. Our results showed that hirudin treatment led to an increase in VEGF expression in the congested skin flaps. Natural hirudin demonstrated more pronounced effects than recombinant hirudin. Further studies are needed to understand the specific mechanisms.

Abstract
A 38-year-old woman presented for evaluation of a firm mass (measuring 20 × 20 mm) in the upper outer quadrant of her left breast. On the basis of the clinical and radiologic findings, we diagnosed a benign breast tumor and scheduled removal by a hand-held vacuum-assisted biopsy device (VABD) under ultrasonographic guidance. Because the first specimen removed from the tumor was white, flaky, and waxy material, we strongly suspected that the lesion was an epidermal cyst. We continued VABD treatment until the tumor was invisible on real-time ultrasonography. Histologic examination demonstrated that the tumor was composed of mature stratified squamous epithelium and laminated layers of keratin, findings consistent with a diagnosis of epidermal cyst. These cysts rarely occur in the breast and are sometimes difficult to distinguish from breast cancer. To our knowledge, this is the first report of an epidermal cyst treated by VABD.
To cascade feedback loops, or not?
Authors: Eitelberg Eduard 
Published: July 2024

AbstractLinear time invariant (LTI) block diagrams—and the associated transfer functions—are profoundly inadequate for multi‐loop control system design. A practitioner has to have a thorough understanding of the physical uncertainties—and of their inter‐dependencies—in the different parts of an interconnected system, or in a given block diagram. Lack of attention to, or understanding of, such causal interactions has led to ill‐advised reliance on cascaded control in practice—and to consternation when cascading fails to yield the expected improvement over a single‐loop design.
Laser‐Inscribable, Moisture‐Responsive Cellulosic Supramolecular Structures with Tunable Broadband Coloration

Published: July 2024

AbstractAdaptive photonic films in response to external stimuli have broad applications in optical communications, sensing, and anticounterfeiting. Yet, it remains challenging to develop photonic structures with tailorable fine patterns that display broadband color changing under ambient conditions. Here a hydrogen‐bonded supramolecular cholesteric liquid crystalline polymer (CLCP) that is mediated by a binary solvent consisting of citric acid (CA) and water is presented. The incorporation of CA not only improves the long‐range order of CLCPs through evaporation‐induced self‐assembly but is also capable of tuning their helical pitch across the entire visible spectrum. The extent of hydration‐induced pitch expansion can be further manipulated by thermal crosslinking, enabling a unique patterning strategy based on mask‐free, programmable laser inscription. High‐precision photonic patterns are created onto CLCPs, which reveal themselves upon hydration in high visual contrast. The study offers a feasible and up‐scaling route toward tailoring environmentally adaptive CLCPs with tunable broadband coloration and highly programmable photonic patterns.

AbstractIncorporating noble‐metal plasmonic nanoparticles (NPs) enhances the optoelectronic properties of perovskite solar cells (PSCs) but at a higher cost. In this work, the overlooked potential of refractory plasmonic materials is highlighted as a cost‐effective alternative additive in PSC research. This investigation aims to stimulate interest in this area by showcasing the theoretical and practical impacts of TiN plasmonic NPs when integrated into PSCs. TiN plasmonic NPs present a cost‐effective yet underexplored option. This study explores the impact of TiN NPs on PSCs through theoretical and experimental approaches. Finite‐difference time‐domain (FDTD) optical simulations and empirical data indicate that TiN NPs increase absorption and reduce reflectance in PSCs, driven by surface plasmon resonance and the significant growth of perovskite grains from 450 to 1400 nm. These NPs also regulate the perovskite crystallization rate by adsorbing DMF/DMSO, fostering larger grain formation. Improved band alignment and decreased trap states enhance charge transport and diminish non‐radiative recombination losses. As a result, PSC efficiency with optimal TiN NP concentration increased from 19.07% to 21.37%. Additionally, TiN‐enhanced PSCs display better stability, retaining 98.1% of their original PCE after 31 days under ambient conditions.

AbstractEngineering oxygen vacancies (Vo) in metal–organic framework (MOF) is considered as an effective strategy to improve the hydrazine oxidation reaction (HzOR) performance. However, the role of Vo and the metal sites for HzOR is still not fully understood. Herein, this study reports the synthesis of a well‐defined bimetallic VO‐rich benzene dicarboxylic acid‐based MOF (NiIr0.03‐BDC) as a model to clarify the intricate catalytic mechanism. Operando characterizations demonstrate that the Vo‐rich environment favors the adsorption of OH− on the catalyst surface during the HzOR process, leading to the formation of Ni(OH)x active species. Theoretical calculations reveal that the introduced Ir at metal nodes not only boosts the HzOR activity of the Ni sites by tuning their electronic structure but also serves as the active sites for hydrogen evolution. As a result, the two‐electrode electrolyzer with NiIr0.03‐BDC || NiIr0.03‐BDC configuration achieved 10 mA cm−2 at an ultralow cell voltage of 0.046 V. This work provides new insights into oxygen vacancy defect engineering of MOFs and paves a solid step for low‐energy consumption hydrogen production.
Hydrogen Sensor with a Thick Catalyst Layer Anchored on Polyimide Film

Published: July 2024

AbstractHydrogen sensors are important in a hydrogen‐driven society to prevent explosions caused by hydrogen leaks into the atmosphere. In previous studies, resistive hydrogen sensors on polymer films have metal oxide nanostructures decorated with novel metals that enable good responses at room temperature. However, the in situ growth process of sensing nanostructures has the disadvantage of ineffective fabrication, particularly when preparing a thick catalyst layer to produce reliable readouts from the catalytic hydrogen combustion. This work presents a catalytic combustion hydrogen sensor with a thick catalyst layer anchored in a UV resin layer on polyimide film. Catalyst anchoring channels are made by UV imprinting with a glass mold. The sensor consists of a sensing electrode and a microheater, both made of Au within an area of 1.2 mm diameter. UV imprinting produces a UV resin layer of 27 µm thick and catalyst anchoring channels of 14 µm deep and 20–30 µm wide, which are filled with Pt/TiO2 as a catalyst. The sensing response is 7.9% for 1% H2 under ambient conditions, and the detection range is 0.1–3% H2. The UV‐resin microstructures can effectively retain a thick catalyst layer to enhance sensitivity, and their low thermal conductivity reduces heat loss.

AbstractPhase change materials (PCM) have greatly contributed to optics with applications ranging from rewritable memories to smart windows. This is possible thanks to the variation in optical properties that PCMs undergo upon thermally‐induced phase change. However, this behavior is accompanied by a loss of optical transparency in one (or more) of their phases, posing a major limitation for transmission‐based functionalities. Here this challenge is addressed by producing PCM‐based composites that remain transparent in the visible spectrum during their phase transition. The cornerstone of this innovative material is the use of 30 nm‐in‐size nanoparticles of paraffin as PCMs, which minimizes the scattering within the polymer host matrix regardless of the paraffin's phase. To demonstrate the potential of this approach, it is shown that thin composite layers can modulate the phase of the incident visible light using temperature, achieving uniform phase profiles with maximum phase shifts up to π radians. Notably, the composites studied exhibit up to threefold larger phase changes for the same input power over reference thermo‐optical materials like polydimethylsiloxane. These findings position paraffin‐based composites as promising materials for various thermo‐optical applications, including wavefront shaping and aberration correction, with the potential to significantly impact a variety of optical technologies.
