Geo-PIFu: Geometry and Pixel Aligned Implicit Functions for Single-view Human Reconstruction (2020)

We propose Geo-PIFu, a method to recover a 3D mesh from a monocular color image of a clothed person. Our method is based on a deep implicit function-based representation to learn latent voxel features using a structure-aware 3D U-Net, to constrain the model in two ways: first, to resolve feature ambiguities in query point encoding, second, to serve as a coarse human shape proxy to regularize the high-resolution mesh and encourage global shape regularity. We show that, by both encoding query points and constraining global shape using latent voxel features, the reconstruction we obtain for clothed human meshes exhibits less shape distortion and improved surface details compared to competing methods. We evaluate Geo-PIFu on a recent human mesh public dataset that is $10 \times$ larger than the private commercial dataset used in PIFu and previous derivative work. On average, we exceed the state of the art by $42.7\%$ reduction in Chamfer and Point-to-Surface Distances, and $19.4\%$ reduction in normal estimation errors.
Catalysis using colloidal-supported gold-based nanoparticles (2014)

The discovery of novel m aterials that can be active, selective and stable catalysts for the efficient transformation of organic molecules to useful products is of high importance. In recent years, there has been significant interest in the utilisation of supported gold-based nanoparticles that can be effective catalysts for a broad range of chemical processes. In this paper, we describe and discuss the utilisation of gold-based nanoparticles as efficient catalysts for a range of important reactions, with particular emphasis placed on our team recent research.

Promotes highly efficient selective catalytic reduction of NOx at relatively low temperatures while not being adversely affected by presence of water vapor and sulfur oxide gases in flue gas. Apparatus utilizing catalyst of this type easily integrated into exhaust stream of power plant to remove nitrogen oxides, generated in combustion of fossil fuels and contribute to formation of acid rain and photochemical smog.
Decision Statistics for Noncoherent Signal Detection in Multi-Element Antenna Arrays (2018)

This article gives a detailed analysis of the characteristics of the exact statistic for the optimal noncoherent signal detection in multi-element antenna arrays. This task is important for reliable initial detection of User Equipment (UE) signals coming from an unknown direction in LTE random access procedure. It is shown that application of the exact statistic is complex because the thresholds of the Neyman-Pearson (NP) criterion depend on the SNR. A detailed comparison of the exact and various approximate decision statistics has been carried out. The results show that the choice of the statistic can make noticeable impact on the probability of missed detection for multi-element antenna array. A new combined decision statistic has been proposed, whose characteristics are close to the exact statistic.
In Vitro and In Vivo Characterization of a Dual-Function Green Fluorescent Protein–HSV1-Thymidine Kinase Reporter Gene Driven by the Human Elongation Factor 1α Promoter (2002)

Toward the goal of monitoring activity of native mammalian promoters with molecular imaging techniques, we stably transfected DU145 prostate carcinoma cells with a fusion construct of enhanced green fluorescent protein (EGFP) and wild-type herpes simplex virus-1 thymidine kinase (HSV1-TK) as a reporter gene driven by the promoter for human elongation factor 1α (EF-1α-EGFP-TK). Using this model system, expression of EGFP was quantified by flow cytometry and fluorescence microscopy, while the HSV1-TK component of the reporter was quantified with 8-[ 3 H]ganciclovir (8-[ 3 H]GCV). As analyzed by flow cytometry, passage of EGFP-TK-DU145 transfected cells (ETK) in vitro resulted in populations of cells with high and low expression of EGFP over time. High and low ETK cells retained 23-fold and 5-fold more GCV, respectively, than control. While differences in uptake and retention of GCV corresponded to relative expression of the reporter gene in each subpopulation of cells as determined by both flow cytometry (EGFP) and quantitative RT-PCR, the correlation was not linear. Furthermore, in high ETK cells, net retention of various radiolabeled nucleoside analogues varied; the rank order was 8-[ 3 H]GCV &lt; 9-(4-fluoro-3-hydroxymethylbutyl)guanine ([ 18 F]FHBG) ≈ 8-[ 3 H]penciclovir (8-[ 3 H]PCV) &lt; 2′-fluoro-2′-deoxy-5-iodouracil-beta-d-arabinofuranoside (2-[ 14 C]FIAU). Xenograft tumors of ETK cells in vivo accumulated 2.5-fold more 8-[ 3 H]GCV per gram of tissue and showed greater fluorescence from EGFP than control DU145 cells, demonstrating that the reporter gene functioned in vivo. These data extend previous reports by showing that a human promoter can be detected in vitro and in vivo with a dual-function reporter exploiting optical and radiotracer techniques.

The anti‐inflammatory effects of 1,25‐dihydroxyvitamin D3 on Th2 cells in vivo are due in part to the control of integrin‐mediated T lymphocyte homing (2004)

Abstract The fat soluble vitamin D3 metabolite 1,25‐dihydroxyvitamin D3 [1,25(OH) 2 D 3 ], and its nuclear receptor play an important role in regulating immune responses. While 1,25(OH) 2 D 3 is known to inhibit transcription of cytokine genes that are required for Th1 differentiation or are products of differentiated Th1 cells, its role in regulating differentiation of Th2 cells is less clear. In this study, we show that 1,25(OH) 2 D 3 has anti‐inflammatory effects in an in vivo Th2‐dependent asthma model. In addition, we demonstrate that 1,25(OH) 2 D 3 down‐regulates the cytoskeleton rearrangement required for promoting integrin‐mediated adhesion of naive and effector CD4 + T cells. Finally, 1,25(OH) 2 D 3 inhibits chemokine‐induced migration of naive cells and their homing to the lymph nodes. Thus, in addition to its regulation of cytokine transcription, 1,25(OH) 2 D 3 regulates migration of cells and thus controls the skewing of various Th subsets in the secondary lymphoid organs and inhibits Th function at sites of inflammation.
Impurity incorporation and exchange interactions in Co2+-doped CdSe/CdS core/shell nanoplatelets (2019)

The intentional incorporation of transition metal impurities into colloidal semiconductor nanocrystals allows an extension of the host material's functionality. While dopant incorporation has been extensively investigated in zero-dimensional quantum dots, the substitutional replacement of atoms in two-dimensional (2D) nanostructures by magnetic dopants has been reported only recently. Here, we demonstrate the successful incorporation of Co<sup>2+</sup> ions into the shell of CdSe/CdS core/shell nanoplatelets, using these ions (i) as microscopic probes for gaining distinct structural insights and (ii) to enhance the magneto-optical functionality of the host material. Analyzing interatomic Co<sup>2+</sup> ligand field transitions, we conclude that Co<sup>2+</sup> is incorporated into lattice sites of the CdS shell, and effects such as diffusion of dopants into the CdSe core or diffusion of the dopants out of the heterostructure causing self-purification play a minor role. Taking advantage of the absorption-based technique of magnetic circular dichroism, we directly prove the presence of sp-d exchange interactions between the dopants and the band charge carriers in CdSe/Co<sup>2+</sup>:CdS heteronanoplatelets. Thus, our study not only demonstrates magneto-optical functionality in 2D nanocrystals by Co<sup>2+</sup> doping but also shows that a careful choice of the dopant type paves the way for a more detailed understanding of the impurity incorporation process into these novel 2D colloidal materials.
Reversible and Irreversible Expansion of Lithium-ion Batteries Under a Wide Range of Stress Factors (2021)

Lithium-ion batteries cell thickness changes as they degrade. These changes in thickness consist of a reversible intercalation-induced expansion and an irreversible expansion. In this work, we study the cell expansion evolution under variety of conditions such as temperature, charging rate, depth of discharge, and pressure.A specialized ?fixture was used to keep the cells at a constant pressure during cycling, while measuring the thickness change both within a cycle and the cumulative growth over many cycles. The changes in positive and negative electrode capacity and stoichiometric range can be diagnosed from the evolution of the reversible expansion. The changes in the reversible expansion if combined with the voltage, lead to a higher-confi?dence estimation of cell health parameters important for lifetime prediction and adoptive battery management such as asymmetric charge/discharge power limits. This study raises the importance of monitoring the expansion for enabling advanced and more-informed health diagnostics of lithium-ion batteries.
Pneumonia recovery reprograms the alveolar macrophage pool (2020)

Community-acquired pneumonia is a widespread disease with significant morbidity and mortality. Alveolar macrophages are tissue-resident lung cells that play a crucial role in innate immunity against bacteria that cause pneumonia. We hypothesized that alveolar macrophages display adaptive characteristics after resolution of bacterial pneumonia. We studied mice 1 to 6 months after self-limiting lung infections with Streptococcus pneumoniae, the most common cause of bacterial pneumonia. Alveolar macrophages, but not other myeloid cells, recovered from the lung showed long-term modifications of their surface marker phenotype. The remodeling of alveolar macrophages was (a) long-lasting (still observed 6 months after infection), (b) regionally localized (observed only in the affected lobe after lobar pneumonia), and (c) associated with macrophage-dependent enhanced protection against another pneumococcal serotype. Metabolomic and transcriptomic profiling revealed that alveolar macrophages of mice that recovered from pneumonia had new baseline activities and altered responses to infection that better resembled those of adult humans. The enhanced lung protection after mild and self-limiting bacterial respiratory infections includes a profound remodeling of the alveolar macrophage pool that is long-lasting; compartmentalized; and manifest across surface receptors, metabolites, and both resting and stimulated transcriptomes.
Preparation and Characterization of La x C60 Thin Films Fabricated by Layer-by-Layer Deposition (1998)

Abstract A modification of physical properties of solid-state C60 when La was doped to C60 thin film as a trivalent metal was examined. the thin film was fabricated by using Layer-by-Layer deposition technique with the multi-sources evaporation system. We found that the C60 film changes its electrical character from the insulator to the semiconductor rapidly upon La doping. the temperature dependence of the electrical conductivity is semiconductive with the activation energy of about 0.3eV.
Charge transfer between plastocyanin and iron hexacyanide (1984)

The electron exchange kinetics between plastocyanin and iron hexacyanide has been studied by laser temperature jump. A general kinetic scheme assuming weak binding of the iron hexacyanide to a distant (10 Å) site has been used to extract intrinsic exchange rates of 68±20 s−1 for Cu(2+) to Cu(1+) reduction, and 200±100 s−1 for the reverse reaction. These intrinsic rates have been compared to simple nonadiabatic tunneling theories and found to be in reasonable agreement.
The Disk and Environment of the Herbig B[CLC]e[/CLC] Star HD 100546 (2001)

Coronagraphic imaging of the nearest Herbig Be star with the Space Telescope Imaging Spectrograph (STIS) on board the Hubble Space Telescope, Ks (2.15 μm) imaging with ADONIS at the 3.6 m telescope at La Silla, and mid-infrared imaging with OSCIR using the 4 m Blanco Telescope at Cerro Tololo Inter-American Observatory confirm the detection of the disk reported by Pantin et al. and map the disk out to 5'' (∼515 AU) in the optical and at Ks. While the source is unresolved at 10 and 18 μm, it can be traced to 15 at 11.7 μm. We confirm the change in the radial dependence of the disk surface brightness near 27 seen at 1.6 μm by Augereau et al. at Ks. No such break in the power law is seen in the optical. The STIS data reveal spiral dark lane structure, making HD 100546 the third near–zero-age main-sequence Herbig Ae/Be star with structure more than 100 AU from the star. We also optically detect a low surface brightness envelope extending 10'' (1000 AU) from the star, in addition to nebulosity, which is probably associated with DC 292.6-7.9. The survival of the envelope through essentially the entire pre–main-sequence lifetime of the star, coupled with the absence of physical companions within 1500 AU of the star, suggests that envelope lifetimes owe more to the star-forming environment than to mass-loss activity from the Herbig Ae/Be star.

Strained Silicon-on-Insulator Platform for Cointegration of Logic and RF—Part I: Implant-Induced Strain Relaxation (2021)

The relaxation of tensile strain in fully depleted (FD) strained silicon-on-insulator (SSOI) by means of ion implantation is experimentally demonstrated in this work. This could enable SiGe p-channel field-effect transistors (pFETs) with high compressive strain (after ion implantation and Ge condensation) to be formed together with Si n-channel field-effect transistors (nFETs) with high tensile strain on the same substrate. From simulations in advanced technology node, 0.8% strain of nFETs and -0.9% strain of pFETs in fin structures can provide saturation drain current and peak G <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">m</sub> enhancements of ~20%-30%. f <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">T</sub> and f <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">max</sub> benefit greatly from strain across the entire range of V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">G</sub> , with their peak values increasing significantly, thus allowing SSOI devices to meet 5G targets.

Hence, the ability to form highly strained nFETs and pFETs together on a common FD-SSOI substrate paves the way for it to become the ultimate high-performance complementary metal-oxide-semiconductor (CMOS) platform for 5G RF and logic circuits. The relaxation of the tensile strain is demonstrated and documented in Part I. A novel Comb-like device architecture to further enhance the SSOI electrical and RF performance is provided in Part II.
2,3-Diphenylthieno[3,4-b]pyrazines as Hole-Transporting Materials for Stable, High-Performance Perovskite Solar Cells (2022)

High-performance and durable perovskite solar cells (PSCs) have advanced rapidly, enabled in part by the development of superior interfacial hole-transporting layers (HTLs). Here, a new series of 2,3-diphenylthieno[3,4-b]pyrazine (DPTP)-based small molecules containing bis- and tetrakis-triphenyl amino donors (1–3) was synthesized from simple, low-cost, and readily available starting materials. The matched energy levels, ideal surface topographies, high hole mobilities of 8.57 × 10–4 cm2 V–1 S–1, and stable chemical structures of DPTP-4D (3) make it an effective hole-transporting material, delivering a PCE of 20.18% with high environmental, thermal, and light-soaking stability when compared to the reference HTL materials, doped Spiro-OMeTAD and PTAA in PSC n-i-p planar devices. Overall, these DPTP-based molecules are promising HTM candidates for the fabrication of stable PSCs.
The candidate guidance molecule, Semaphorin 5B, is over-expressed in kidney cancers (2005)

1523 Semaphorins are a family of secreted and transmembrane proteins with roles in axonal guidance, vasculogenesis, and cellular immunity. Recently, members of this family have been implicated in human cancers. Expression of the transmembrane semaphorin, Sema5B, is elevated in various kidney cancers, including clear cell carcinoma and renal adenocarcinoma; expression is low in all normal adult tissues examined. The predicted extracellular domain of Sema5B comprises sema and PSI domains and a series of juxtamembrane thrombospondin type I repeats. We have found that the expression of Sema5B is regulated by oxygen tension and is enhanced by loss of function of pVHL (the von Hippel Lindau protein), a common feature of renal cancers. Additionally, the expression of Sema5B in renal cell carcinomas correlates strongly with the expression of vascular endothelial growth factor (VEGF), a protein known to be up-regulated by hypoxia and a key mediator of angiogenesis in malignancy. The mouse putative ortholog, SemaG, is expressed through embryonic day 12 in a broad mesodermal and ectodermal pattern, consistent with a role in vasculogenesis during development; expression in the brain is also observed, as previously reported. Together, these data suggest an angiogenic and/or migratory function of Sema5B in renal cancer.
Novel Nematic Compounds Incorporating Two Conjugated Carbon-Carbon Double Bonds in the Terminal Chain (1999)

Abstract The position and configuration of a carbon-carbon double bond strongly influence the transition temperatures, elastic and dielectric constants, viscosity, birefringence, etc of nematic liquid crystals incorporating them. This behaviour can probably be attributed to conformational effects and anisotropic π electron density distribution and can be used to improve the optical performance of STN-LCDs. However, relatively few liquid crystals incorporating two carbon-carbon double bonds have been reported[1–3]. Therefore, we have synthesised a wide variety of new compounds incorporating two conjugated trans-carbon-carbon double bonds in the same terminal chain. The effects on their physical properties on the presence of two double bonds have been compared with those of the corresponding material either without a carbon-carbon double bond or with just one carbon-carbon double bond in the same position. Strong non-additive effects were found and of the dienes prepared exhibit high birefringence and nematic clearing points as well as being of surprisingly low viscosity.

Toughening polylactide with a catalyzed epoxy‐acid interfacial reaction (2017)

Polylactide (PLA) is a promising material, with favorable modulus, renewable sources, and biodegradability. However, its low extension at break (4–7%) and toughness (notched Izod, 26 J/m) limit its applications (Anderson et al., Polym. Rev., 48, 85 (2008)). PLA toughening has been the subject of recent reviews, and is the basis for several commercial products. This work aims to increase PLA toughness using rubbery, linear low‐density polyethylene (LLDPE), glycidyl methacrylate functional PE compatibilizer (EGMA), and novel catalysts that promote copolymer formation at the interface of immiscible blends of PLA and EGMA/LLDPE. Droplet size was reduced from 2.7 µm to 1.7 µm with addition of 5 wt% EGMA, and further to 1.0 µm with the addition of cobalt octoate catalyst. Extension at break of 200% is achieved with only 5 wt% EGMA, 15 wt% LLDPE, and 0.01 M cobalt octoate, leading to an increase in tensile toughness of over an order of magnitude (compared to neat PLA). This work demonstrates that catalysts can reduce the amount of reactive compatibilizer necessary to achieve a given PLA toughness. POLYM. ENG.

Total syntheses of natural (+)-(4R,6R)-4-hydroxy-6-pentylvalerolactone and of (–)-(6R)-massoialactone (1991)

An asymmetric total synthesis and hence a confirmation of the absolute configuration of naturally occurring (+)-(4R,6R)-4-hydroxy-6-pentylvalerolactone 10, a metabolite of Cephalosporium recifei, is described, starting from the yeast reduction product methyl (3R)-3-hydroxyhex-5-enoate 5. The key step is a highly trans-selective kinetic iodolactonization of the unsaturated acid 16e. Dehydration of the lactone 10 leads to natural (–)-(6R)-massoialactone 11.
CMB Analysis of Boomerang & Maxima & the Cosmic Parameters {Omega_tot,Omega_b h^2,Omega_cdm h^2,Omega_Lambda,n_s} (2000)

We show how estimates of parameters characterizing inflation-based theories of structure formation localized over the past year when large scale structure (LSS) information from galaxy and cluster surveys was combined with the rapidly developing cosmic microwave background (CMB) data, especially from the recent Boomerang and Maxima balloon experiments. All current CMB data plus a relatively weak prior probability on the Hubble constant, age and LSS points to little mean curvature (Omega_{tot} = 1.08\pm 0.06) and nearly scale invariant initial fluctuations (n_s =1.03\pm 0.08), both predictions of (non-baroque) inflation theory. We emphasize the role that degeneracy among parameters in the L_{pk} = 212\pm 7 position of the (first acoustic) peak plays in defining the $\Omega_{tot}$ range upon marginalization over other variables. Though the CDM density is in the expected range (\Omega_{cdm}h^2=0.17\pm 0.02), the baryon density Omega_bh^2=0.030\pm 0.005 is somewhat above the independent 0.019\pm 0.002 nucleosynthesis estimate. CMB+LSS gives independent evidence for dark energy (Omega_\Lambda=0.66\pm 0.06) at the same level as from supernova (SN1) observations, with a phenomenological quintessence equation of state limited by SN1+CMB+LSS to w_Q<-0.7 cf. the w_Q=-1 cosmological constant case.
