On Gauge Equivalence of Tachyon Solutions in Cubic Neveu-Schwarz String Field Theory
Full text linkSimple analytic solution to cubic Neveu-Schwarz String Field Theory including
the sector is presented. This solution is an analog of the
Erler-Schnabl solution for bosonic case and one of the authors solution for the
pure case. Gauge transformations of the new solution to others known
solutions for the string tachyon condensation are constructed explicitly.
This gauge equivalence manifestly supports the early observed fact that these
solutions have the same value of the action density.Comment: 8 pages, LaTe
High-contrast dark resonance on the D2 - line of 87Rb in a vapor cell with different directions of the pump - probe waves
Full text linkWe propose a novel method enabling to create a high-contrast dark resonance
in the 87Rb vapor D2-line. The method is based on an optical pumping of atoms
into the working states by a two-frequency, linearly-polarized laser radiation
propagating perpendicularly to the probe field. This new scheme is compared to
the traditional scheme involving the circularly-polarized probe beam only, and
significant improvement of the dark resonance parameters is found. Qualitative
considerations are confirmed by numerical calculations.Comment: 7 pages, 4 figure
PENGARUH STRES DAN MOTIVASI KERJA TERHADAP PRESTASI KERJA KARYAWAN DI PT. BANK TABUNGAN NEGARA (PERSERO) TBK KANTOR CABANG BANDUNG
Get PDFABSTRAK
Penelitian ini berawal dari ditemukannya masalah prestasi kerja yang belum optimal yang disebabkan oleh adanya stres kerja dan rendahnya motivasi kerja. Tujuan penelitian ini adalah untuk mengetahui dan menganalisa pengaruh stres kerja dan motivasi kerja terhadap prestasi kerja karyawan baik secara simultan maupun parsial di PT. Bank Tabungan Negara Kantor Cabang Bandung.
Penelitian ini menggunakan pendekatan kuantitatif. Teknik pengumpulan data yang digunakan adalah penelitian lapangan (field research), studi kepustakaan (library research), dan angket penelitian. Metode analisis data yang digunakan adalah metode analisis linier regresi berganda, korelasi berganda, dan koefisien determinasi. Hasil penelitian ini menunjukan bahwa stres kerja berpengaruh negatif dan signifikan terhadap prestasi kerja karyawan. Motivasi kerja berpengaruh positif dan signifikan terhadap prestasi kerja karyawan. Sementara itu variabel stres dan motivasi berpengaruh signifikan bersama-sama terhadap prestasi kerja karyawan di PT. Bank Tabungan Negara Kantor Cabang Bandung.

Design of Allosteric Stimulators of the Hsp90 ATPase as New Anticancer Leads
Get PDFAllosteric compounds that stimulate Hsp90 adenosine triphosphatase (ATPase) activity were rationally designed, showing anticancer potencies in the low micromolar to nanomolar range. In parallel, the mode of action of these compounds was clarified and a quantitative model that links the dynamic ligand-protein cross-talk to observed cellular and in vitro activities was developed. The results support the potential of using dynamics-based approaches to develop original mechanism-based cancer therapeutics
New Loop Representations for 2+1 Gravity
Get PDFSince the gauge group underlying 2+1-dimensional general relativity is
non-compact, certain difficulties arise in the passage from the connection to
the loop representations. It is shown that these problems can be handled by
appropriately choosing the measure that features in the definition of the loop
transform. Thus, ``old-fashioned'' loop representations - based on ordinary
loops - do exist. In the case when the spatial topology is that of a two-torus,
these can be constructed explicitly; {\it all} quantum states can be
represented as functions of (homotopy classes of) loops and the scalar product
and the action of the basic observables can be given directly in terms of
loops.Comment: 28pp, 1 figure (postscript, compressed and uuencoded), TeX,

Pengaruh Penggunaan Beberapa Mulsa Plastik Dan Varietas Terhadap Serangan Penyakit Antraknosa (Colletotrichum Capsicii Sydow.) Pada Tanaman Cabai (Capsicum Annum L.) Di Lapangan
Full text linkHe influence of the use of plastic mulchs and Chili varieties on the attack of antracnose(Colletotrichum capsicii Sydow.) on Chili plants (Capsicum annum L.) in the field. The aim of the research was to know the appropriate type of mulchs which could be used to curbthe attack of antracnose and which Chili varieties are resistant against antracnose. The researchused Cluster Random Design (CRD) Factorial which consisted of two factors and threerepetitions. The first factor was plastic mulchs: non mulch (M0). silver (M1). and black (M2) the second factor was varieties: Lado F1 (V1). Lembang 1 (V2). Tanjung 2 (V3). The resultshowed that silver black mulch was the best to inhibite antracnose (1.08 %) with Lado F1(1.12%) and the highest on no mulch (7.82 %) with Tanjung 2. Interaction of no mulch andTanjung 2 were lowest (1.70%) and the highest (11.46%) on no mulch and Tanjung 2. Thehighest production (0.72 ton/ha) on silver black mulch with Lado F1 (0.63 to/ha) and the loweston no mulch (0.20 ton/ha) with Tanjung 2 (0.17 ton/ha). Interaction of black silver mulch andLado F1 were highest (0.89 ton/ha) and the lowest (0.15 ton/ha) on no mulch and Tanjung 2
